Description

Camera module and array camera module based on integrated packaging technology

Technical Field

The invention relates to the field of camera modules, in particular to a camera module and an array camera module based on an integrated packaging process.

Background

The camera module is one of the parts of the intelligent electronic device that cannot be obtained, for example, but not limited to, the intelligent electronic device such as a smart phone, a camera, a computer device, and a wearable device. And along with the continuous development and the popularization of various smart machines, the requirement to the module of making a video recording is also higher and higher.

In recent years, the development of intelligent electronic devices has been rapidly increased, and the smart electronic devices are increasingly light and thin, and the camera module is adapted to the development of the smart electronic devices, and is also increasingly required to be multifunctional, light, thin and small, so that the smart electronic devices can be thinner and thinner, and the imaging requirements of the devices on the camera module are met. Therefore, manufacturers of camera modules are continuously dedicated to designing and manufacturing camera modules satisfying these requirements.

The molding packaging technology is a packaging technology which is newly developed on the basis of the traditional COB packaging technology. As shown in fig. 1A, is a circuit board packaged using existing molded package technology. In this structure, the mold part 1 is mold-sealed to the circuit board 2, the chip 3 is then connected to the circuit board 2, and the optical filter 4 is mounted on the mold part 1. Wherein the electronic component 5 on the cladding circuit board of mould portion 1 to reduce the independent space that occupies of the electronic component 5 of the module of making a video recording, make the size of the module of making a video recording reduce, and solve the problem that the formation of image quality of the module of making a video recording is influenced to the dust that adheres to on the electronic component.

Referring to fig. 1B, a conventional COB-packaged circuit board has a chip attached to the circuit board 2, and a lens holder 7 attached to the circuit board 2. More specifically, the mirror base 7 has a support leg 701 at the bottom, and the mirror base 7 is adhered to the circuit board 2 through the support leg 701. However, since the lens holder 7 needs to avoid the electronic component 5, the bottom side area of the supporting leg 701 is small, so that the contact area between the supporting leg 701 and the circuit board 2 is small, and accordingly, the bonding area between the supporting leg 701 and the circuit board 2 is also limited, so that the supporting leg 701 is easily separated from the circuit board 2 based on the camera module obtained by the conventional COB packaging technology, and the connection between the lens holder 7 and the circuit board 2 is not firm. Moreover, the lens mount 7 generally needs to be matched with a lens or a lens assembly having a driver or a fixed lens barrel, so that the stress of the lens or the lens assembly on the lens mount 7 is transmitted to the supporting leg 701 with a smaller size, which easily causes the supporting leg 701 to be damaged due to too much stress concentration. In addition, the supporting legs 701 and the portion above the supporting legs 701 of the conventional lens holder 7 for mounting the optical filter all need to have a predetermined thickness, so that the thickness of the conventional lens holder 7 is relatively large, and is generally higher than 0.7 mm.

Compared with the conventional COB packaging technology, the molding packaging technology has numerous advantages, such as the molding part 1 replaces the lens base 7, the independent occupied space of the electronic element 5 is reduced, and the camera module ruler is reduced; the dust attached to the electronic element 5 is prevented from influencing the imaging quality of the camera module, and the like, but the structure brings new problems.

The optical filter is an important element in a modern camera module, and filters infrared light in light, so that the light is closer to the effect observed by human eyes. The optical filter is easily damaged, occupies a large proportion in the manufacturing cost of the whole camera module, is more expensive when the area is larger, and is more difficult to control the manufacturing precision when the area of the optical filter is larger, so the optical filter becomes a difficult implementation in the molding and packaging technology.

First, compared to the conventional COB package method, the mold package method uses the molding part to cover the electronic component 5, and utilizes the spatial position of the electronic component 5, but the molding part increases the installation space of the upper filter 4 relative to the lens holder of the COB, that is, the area of the filter 4 required by the mold package is larger.

Specifically, referring to fig. 1B, the conventional COB filter is mounted on the lens holder 7, and since the lens holder 7 is mounted on the circuit board 2 at a later stage, the conventional COB filter can be manufactured into different shapes, such as extending inward, so that the area of the filter can be reduced as much as possible on the basis of ensuring that the photosensitive area is not blocked, and thus the conventional COB filter is more convenient to mount on the basis of ensuring the use requirement, and the price of the filter with a small area is lower, so that the cost of the whole camera module is reduced, and in the molding package, the molding part 1 is integrally formed on the circuit board 2 through a mold, and the molding part integrally extends from bottom to top, so that the area of the filter 4 is determined by the opening of the molding part 1, and the area of the required filter 4 is larger.

Secondly, in the mold encapsulation manner, referring to fig. 1A, the optical filter 4 needs to be installed in the groove 6 of the mold part 1, and based on the mold encapsulation process, the shape of the corner opening is difficult to control, that is, the groove walls forming the groove 6, especially the positions where the groove walls meet, may be deformed, such as burrs, so that good installation conditions cannot be provided for the optical filter 4, flatness cannot be ensured, and the optical filter is easily damaged. And for the conventional lens holder 7, an inner groove 8 is provided, that is, the lens holder 7 can extend inwards, so as to provide a position for mounting the optical filter 4 and reduce the installation area of the optical filter 4. Since the molding process is a one-step molding process, there is a problem of mold drawing during the manufacturing process by a mold, so that the conventional lens holder structure cannot be manufactured by molding, and the molded package is limited to some specific structures, such as the molded part 1 without the inner recess 8. The conventional lens holder and the molded package lens holder have relative advantages and disadvantages and the corresponding forming process, so that the advantages of the two are combined.

Third, even if the mold part 1 is formed in a flat shape without forming the recess 6, it is possible to ensure good flatness of the surface and provide good mounting conditions for the optical filter 4. However, in this structure, on one hand, the optical filter 4 needs to be coordinated with other components such as a lens or an actuator to distribute the package portion, which has a high requirement on the mounting accuracy, and the other components can easily damage the optical filter during the mounting process; on the other hand, the distance between the optical filter and the lens is short, the lens in the lens is easy to touch the optical filter, and the back focal length of the lens is increased.

In addition, the circuit board is required to be provided with the photosensitive element, the electronic element and the molding part, the layout mode of the components influences the area of the circuit board, and the width of the molding mode based on the packaging part is usually larger than that of the traditional mirror seat, so the occupied area on the circuit board is increased.

The mold packaging process is an important application process recently developed in the field of camera modules, and although it is a well-known technology in other fields, in the field of camera modules, especially for multi-lens and high-pixel camera modules which are popular recently, the mold packaging process shows more advantages and importance, and enters a stage suitable for application. Compared with the traditional COB-packaged camera module, the camera module based on the molding packaging process has the advantages that the lens base is formed through molding packaging, the traditional independent lens base is replaced, the size of the camera module can be reduced, the flat mounting surface is provided, and the like. As mentioned above, the lens holder formed by the molded package is not suitable for directly mounting the filter element. On the other hand, the layout mode of the photosensitive elements and the electronic components on the circuit board can influence the size of the camera module. According to the invention, the camera module and the array camera module based on the integrated packaging process and the filter element lens base thereof are provided, wherein the filter element lens base is introduced into the camera module and the array camera module based on the integrated packaging process, so that the filter element lens base is matched with the integrated base to play a role of the traditional lens base, and on the basis of applying the integrated packaging process, such as a molding integrated forming process, good mounting conditions can be provided for a filter element, a driver or a lens, mounting problems caused by the integrated packaging process are compensated, all parts on a circuit board are more reasonably arranged, the space of the circuit board is fully utilized, and the size of the camera module is further reduced.

As shown in fig. 2 to 4, the present invention is a camera module according to a first preferred embodiment of the present invention. The camera module 100 can be applied to various electronic devices, such as but not limited to smart phones, wearable devices, computer devices, televisions, vehicles, cameras, monitoring devices, and the like, and the camera module 100 is used with the electronic devices to capture and reproduce images of a target object.

As shown in fig. 2 to 4, the present invention is a camera module according to a first preferred embodiment of the present invention. The camera module 100 includes an integrated base assembly 10, a photosensitive element 20, a lens 30, a filter lens holder 40 and a filter element 50.

The integrated base assembly 10 includes an integrated base 11 and a circuit board 12, the integrated base 11 is integrally packaged on the circuit board 12, for example but not limited to, integrally molded on the circuit board 12, and the filter lens base 40 is mounted on the integrated base 11, so that the integrated base 11 and the filter lens base 40 cooperate with each other to replace a lens base or a bracket of a conventional camera module, and the lens base or the bracket does not need to be attached to the circuit board through glue like in a conventional packaging process. The light sensing element 20 is operatively connected to the circuit board 12. The photosensitive element 20 is electrically connected to the circuit board 12 of the integrated base assembly 10, the filter element lens holder 40 is mounted on the integrated base assembly 10, and the lens 30 is located in a photosensitive path of the photosensitive element 20.

The integrated base 11 has an optical window 111 and a base main body 112 forming the optical window 111, the optical window 111 provides a light path for the photosensitive element 20, and the base main body 112 is integrally encapsulated in the circuit board 12 by molding. In particular, in this embodiment, the light window 111 is a closed-loop structure so as to provide a closed inner environment for the lens 30. The circuit board 12 includes a substrate 121, and a plurality of electronic components 122 formed on the substrate 121, such as mounted by SMT, wherein the electronic components 122 include, but are not limited to, resistors, capacitors, driving devices, and the like. In this embodiment of the present invention, the integrated base 11 is integrally packaged on the substrate 121 and integrally covers the electronic component 122, so as to prevent dust and impurities from adhering to the electronic component 122 and contaminating the photosensitive element 20 to affect the imaging effect, similar to that in a conventional camera module. It is understood that in another modified embodiment, it is also possible that the electronic component 122 is embedded in the substrate 121, i.e., the electronic component 122 may not be exposed. The substrate 121 of the circuit board 12 may be a hard PCB, a soft PCB, a rigid-flex board, a ceramic substrate, etc. It should be noted that, in the preferred embodiment of the present invention, since the integrated base 11 can completely cover the electronic components 122, the electronic components 122 may not be embedded in the substrate 121, and the substrate 121 is only used for forming the conductive traces, so that the finally manufactured integrated base assembly 10 has a smaller thickness.

It should be noted that, in some embodiments, the electronic component 122 is disposed around the photosensitive element 20, and in different embodiments, the disposition position of the electronic component 122 may be designed and arranged as required, for example, concentrated on one side or two sides, and may be matched with the disposition position of the photosensitive element 20, the subsequent disposition position of the electrical connection element 203, and the shape of the filter element lens holder 40, so as to more reasonably utilize the spatial position on the substrate 122 and reduce the size of the camera module as much as possible, and those skilled in the art should understand that the disposition position and the type of the electronic component 122 are not a limitation of the present invention. It should be noted that in the actual cross-sectional view, due to the different arrangement positions of the electronic components 122, the electronic components may not be visible or may only be seen on one side in the cross-sectional view, but in the drawings of the present invention, the electronic components 122 are visible in the cross-sectional view for the convenience of understanding and explanation, and the present invention is not limited in this respect.

More specifically, the substrate 121 has an upper surface 1211 and a lower surface 1212, the upper surface 1211 is opposite to the lens 30, and the lower surface 1212 is opposite to the lens 30. The photosensitive element 20 includes a front surface 201 and a back surface 202, the front surface 201 is opposite to the lens 30 for performing a photosensitive action, and the back surface 202 is opposite to the lens 30 for being attached to the upper surface 1211 of the substrate 121. The photosensitive element 20 is electrically connected to the substrate 121 through at least one electrical connection element 203. The electrical connection element 203 is exemplified by, but not limited to, gold wire, silver wire, copper wire, aluminum wire. The electrical connection elements 203 may be disposed on one side, two sides, three sides, or four sides of the photosensitive element 20, and in some drawings of the present invention, an embodiment in which the electrical connection elements 203 are disposed on four sides is taken as an example for illustration, but in other embodiments, the electrical connection elements 203 may be disposed on one side, two sides, or three sides as needed, and it should be understood by those skilled in the art that the number, location, and type of the disposed electrical connection elements 203 are not a limitation of the present invention.

The photosensitive element 20 is mounted On the substrate 121 by, for example, but not limited to, a Surface Mount Technology (SMT), and is electrically connected to the substrate 121 by a cob (chip On board) gold wire bonding method. Of course, in other embodiments of the present invention, the photosensitive element 20 may be mounted on the substrate 121 in other manners, such as embedded, FC (Flip Chip), etc., and it should be understood by those skilled in the art that the connection and mounting manner of the photosensitive element 20 and the circuit board 12 is not limited by the present invention.

More specifically, the front surface 201 of the photosensitive element 20 has a photosensitive region 1311 and a non-photosensitive region 1312, and particularly, the non-photosensitive region 1312 surrounds the photosensitive region 1311. The photosensitive region 1311 is used for performing a photosensitive action to convert an optical signal into an electrical signal, and the non-photosensitive region 1312 is electrically connected to the circuit board 12 through the electrical connection element 203 to transmit the electrical signal to the circuit board 12. The lens 30 is aligned with the photosensitive element 20, and the optical axes are the same, so that the light passing through the lens 30 can reach the photosensitive element 20 through the optical window 111, and further after photoelectric conversion of the photosensitive element 20, an electrical signal can be transmitted to the circuit board 12, so that the image information can be acquired by the camera module 100.

As shown in fig. 2 and 3, the camera module 100 includes a filter element 50 for filtering the light passing through the lens 30. The filter element 50 is exemplified by, but not limited to, an infrared cut filter, a blue glass filter, a wafer level infrared cut filter, a total transmittance film, a visible light filter. The filter element 50 is mounted on the filter element mount 40 and is located in a light path of the photosensitive element 20. The camera module may further include a driver 60, such as a voice coil motor, a piezoelectric motor, etc. The lens 30 is mounted to the actuator 60 so as to form a moving focus camera module, i.e., an af (auto focus) camera module. The driver 60 includes at least one pin 61, and the driver 60 is operatively connected to the circuit board 12 through the pin 61. The pins 61 may be one of single pins, double pins, single row pins, or double row pins. In some of the drawings of the present invention, a two-pin example is illustrated, but not limited. The pin 61 is normally located close to the edge, in a cross-section taken from a position corresponding to line a-a in the position of fig. 3, corresponding to the cross-sectional view of fig. 2, while the pin 61 is not actually visible in the cross-sectional view corresponding to fig. 2, but for ease of understanding and explanation the presence of the pin 61 is indicated by a dashed line in the corresponding cross-section. It will be understood by those skilled in the art that the type, shape and placement of the pins 61 are not a limitation of the present invention.

As shown in fig. 2 to 4, the filter element 50 is mounted on the filter element mount 40 and is sunk in the optical window 111 of the integrated base 11. The unitary base 11 of the unitary base assembly 10 has a top surface 113, the filter mount 40 is mounted to the top surface 113 of the unitary base 11, and the actuator 60 is mounted to the filter mount 40. According to this embodiment of the invention, the top surface 113 of the integral base 11 extends planarly. In other words, the integrated base 11 forms a platform structure without a step protrusion, and the filter element mount 40 is mounted to the platform structure. It is worth mentioning that in this manner, the top surface 113 of the integrated base 11 extends planarly without significant bending angles, so that a more even and burr-free mounting surface can be obtained during the integrated packaging process, such as molding, to provide a flat mounting condition for the filter element lens holder 40.

It is worth mentioning that the filter element 50, such as a blue glass filter, is a relatively fragile and relatively expensive element that is easily broken, and therefore protecting the filter element 50 is also an extremely important aspect in the camera module manufacturing process. In the present invention, the integrated base 11 is manufactured by a molding process such as injection molding or mold pressing, and the material of the filter element mount 40 is not limited as long as it has sufficient strength to carry the filter element 50. Preferably, the filter element holder 40 and the integrated base 11 can be manufactured by different manufacturing processes, such as an injection molding process to manufacture the filter element holder 40, and a transfer molding process to manufacture the integrated base 11, so that different materials can be used, thereby making the filter element holder 40 and the integrated base 11 have different hardness and different surface flexibility, such as better flexibility of the filter element holder 40, so that when the filter element 50 is mounted on the filter element holder 40, the stress applied to the filter element holder 40 is smaller than that applied to the integrated base 11, thereby more suitably mounting the filter element 50, and causing damage or chipping of the filter element 50. That is, the filter element mount 40 relieves external stresses to which the filter element 50 may be subjected, such as stresses to which it is directly bonded to the unitary base 11.

Further, the filter element mount 40 has at least one supporting slot 41 and at least one engaging slot 42, the supporting slot 41 is used for mounting the filter element 50, and the engaging slot 42 is used for mounting to the integrated base 11. The supporting slot 41 is connected to the light window 111 to form an accommodating opening 411 for accommodating the filter element 50. The engaging groove 42 surrounds the bottom periphery of the filter element lens holder 40. In other words, the filter element mount 40 has the receiving opening 411 for receiving the filter element 50, so that the filter element 50 is located in the photosensitive path of the photosensitive element 20.

It should be noted that the filter element 50 is mounted in the supporting groove 41, and the relative height between the filter element mount 40 and the filter element 50 is reduced, so that the filter element 50 does not protrude or protrudes less from the filter element mount 40, and the height of the camera module 100 is not increased, and the lens 50 or the driver 60 is not easily touched.

In other words, the supporting groove 41 forms an inner loop so as to mount the filter element 50 inside the filter element mount 40 and located in the light path of the photosensitive element 20. The engaging groove 42 forms an outer loop for engaging the integrated base 11, and provides a mounting position for the filter element mount 40 through the integrated base 11.

More specifically, the shape of the engagement groove 42 matches the shape of the integrated base 11, so that the filter element holder 40 is stably mounted to the integrated base 11.

Further, referring to fig. 2 to 4, the filter holder 40 includes a filter holder main body 43, at least one inward extending arm 44, and at least one sinking arm 45, and the sinking arm 45 extends integrally in a longitudinal direction and turns from the filter holder main body 43, so that the mounting position of the filter element 50 is sunk into the optical window 111. The inwardly extending arm 44 is integrally extended in a direction turning and transverse direction from the sinking arm 45 so as to provide a horizontal mounting position for the filter element 50, so that the optical axes of the filter element 50 and the photosensitive element 20 are coincident. In the example shown, the filter element mount 40 includes four integrally connected inner arms 44 and four integrally connected lower arms 45, each of the inner arms 44 and each of the lower arms 45 extending at different positions to form the annular integral filter element mount 40.

In other words, the sinking arm 45 is integrally extended longitudinally inside the filter holder body 43, the engaging groove 42 is formed at the bottom side of the filter holder body 43 so as to be engaged with the integrated base 11, the inwardly extending arm 44 is transversely extended inside the sinking arm 45, and the supporting groove 41 is formed at the top side of the inwardly extending arm 44 so as to support the filter 50.

In one embodiment, the engaging groove 42 of the filter element mount 40 has a shape corresponding to the shape of the optical window 111 formed by the integrated base 11, and the supporting groove 41 has a shape corresponding to the shape of the filter element 50. Specifically, the filter element 50 has a square structure, and the top view of the supporting groove 41 has an annular structure, such as a square ring.

The filter element mount 40 has the receiving opening 411 for receiving the filter element 50, so that the filter element 50 is located in the photosensitive path of the photosensitive element 20. Specifically, the lens holder main body 43 and the inwardly extending arm 44 form the receiving opening 411, that is, the extending length of the inwardly extending arm 44 determines the minimum area required by the filter element 50. It is worth mentioning that in the molding and packaging process, the inwardly extending arms 44 cannot be formed, so that the area of the filter element is larger, or the area of the filter element is increased relative to that required by the conventional lens holder, whereas in the present invention, the inwardly extending arms 44 extend inwardly, so that the required area of the filter element 50 is reduced, and the advantages of the filter element lens holder 40 and the advantages of the integrated package are combined.

For example, referring to fig. 2, the distance between the inwardly extending arms 44 on opposite sides is marked as L, and the diameter of the filter element 50 only needs to be larger than L, so that the filter element 50 can be mounted on the inwardly extending arms 44 without being mounted on the base main body 112, thereby reducing the required area of the filter element 50.

It is worth mentioning that the extension distance of the sinking arm 45 affects the sinking depth of the filter element 50 in the light window 111, and the extension distance of the inner extending arm 44 affects the size of the area of the filter element 50 installed. For example, when the sinking arm 45 extends a greater distance, the filter element 50 sinks in the light window 111, the distance from the light sensing element 20 is smaller, and the back focal length of the corresponding camera module 100 is smaller; when the extending distance of the inner extending arm 44 is longer, the smaller the receiving opening 411 of the filter element lens holder 40 is, the smaller the area of the filter element 50 is required to be, so that the filter element 50 is more suitable to be obtained, the installation is convenient, and the cost of the camera module 100 is reduced. Certainly, the extending distance of the sinking arm 45 needs to be combined with the imaging effect of the camera module, for example, dark spots such as dust images are not generated on the basis of reducing the back focus; the extending distance of the inner extending arm 44 needs to take into consideration factors such as the light path of the camera module 100, the photosensitive region 1311 and the non-photosensitive region 1312 of the photosensitive element 20, and the remaining width of the circuit board 12, for example, when the inner extending arm 44 extends inward, the inner extending arm 44 does not block the photosensitive region 1311 of the photosensitive element 20 and does not block the incoming light flux too much under the condition that the filter element 50 is small, and the inner extending arm can extend more at the position where the package of the circuit board 12 is wide and extend less at the position where the package of the circuit board 12 is small, so that the area of the filter element 50 is reduced as much as possible under the condition that the imaging quality is ensured.

The shape of the filter element mount 40 is matched to the shape of the integral base 11. In some embodiments, the integral base 11 is approximately regular symmetrical, such as a square ring, and accordingly, the filter element mount 40 is symmetrical, the filter element mount body 43 is regular, the inwardly extending arms 44 are uniform, and the downwardly extending arms 45 are uniform. In other embodiments, because the electronic component 122 to be encapsulated is located at a different position, the interior of the integrated base 11 has an inward protruding position and a different width, and accordingly, the filter element mount body 43 may be provided with a corresponding groove or protruding position, or the lengths of the inner extending arms 44 are different to adapt to the shape of the integrated base 11, the position of the photosensitive element 20, and the installation of the filter element 50 is facilitated.

In some embodiments, the filter element mount 40 may be mounted on the integrated base 11 by means of glue bonding, and the flatness of the filter element mount 40 may be adjusted by the thickness of the glue.

It should be noted that, in this embodiment of the present invention, the integrated base 11 is encapsulated on the upper surface 1211 of the circuit board 12, while in other embodiments of the present invention, the integrated base 11 may extend to the side and/or bottom surface of the circuit board 12, and it should be understood by those skilled in the art that the integrally molded scope of the integrated base 11 is not limited by the present invention.

In an embodiment, in the assembling process of the integrated base assembly 10 and the filter element mount 40 of the camera module 100, referring to fig. 4, the integrated base 11 is formed on the substrate 121, then the filter element 50 is mounted on the filter element mount 40, and further the filter element mount 40 with the filter element 50 is mounted on the integrated base 11, so that the mounting process of the filter element 50 is relatively conveniently completed.

It should be noted that, in the embodiment of the present invention, the substrate 121 is a flat plate, and the photosensitive element 20 is attached to the upper surface 1211 of the substrate 121. In another embodiment, the substrate 121 may have an inner groove, and the photosensitive element 20 is received in the inner groove to reduce the height of the photosensitive element 20 protruding from the substrate 121. In another embodiment, the substrate 121 may have a through hole communicating with both sides of the substrate 121, and the photosensitive element 20 is accommodated in the through hole, so that the relative position between the photosensitive element 20 and the substrate 121 is adjustable, for example, the upper surface of the photosensitive element 20 is disposed in correspondence with the upper surface 1211 of the substrate 121 or the lower surface of the photosensitive element 20 is disposed in correspondence with the lower surface 1212 of the substrate 121. In another embodiment, the substrate 121 may have a via with a stepped structure, and the photosensitive element 20 is flip-chip mounted in the via. In another embodiment, the base plate 121 may have a reinforcing hole into which the integrated base 11 extends, enhancing the structural strength of the integrated base 11 assembly 10. In another embodiment, the circuit board 12 includes a back plate laminated on the bottom of the substrate 121 to enhance the structural strength and heat dissipation performance of the integrated base assembly 10, such as but not limited to a metal plate. In another embodiment, the integrated base assembly 10 includes an electromagnetic shielding layer, which is wrapped outside or surrounds the integrated base 11 to enhance the electromagnetic interference resistance of the camera module 100. In other embodiments of the present invention, the circuit board 12 may have other various modifications to enhance or enhance the different properties of the integrated base assembly 10, and those skilled in the art will appreciate that the above-described structural modifications of the circuit board 12 are not limitations of the present invention.

In the above-described embodiment of the present invention, the filter element mount 40 is mounted to the integrated base 11, and the actuator 60 is mounted to the filter element mount 40, that is, the filter element mount 40 is disposed between the actuator 60 and the integrated base 11. In yet another variant embodiment of the invention, with reference to fig. 5, both the filter element mount 40 and the actuator 60 are mounted to the top surface 113 of the unitary base 11. Further, the filter element mount 40 is mounted adjacent to the inside of the unitary base 11, and the actuator 60 is mounted adjacent to the outside of the unitary base 11, so that the actuator 60 and the filter element mount 40 cooperatively distribute the top surface 113 of the unitary base 11.

It should be noted that in the above preferred embodiment of the present invention, the camera module 100 includes the actuator 60, and the lens 30 is mounted on the actuator 60, so as to form a moving focus camera module AF capable of automatically adjusting the focal length, while in another embodiment of the present invention, referring to fig. 6, the camera module 100 does not include the actuator 60, and forms a fixed focus camera module, i.e., ff (fix focus) camera module, and the lens 30 is directly mounted on the filter base 40. It should be understood by those skilled in the art that the type of camera module 100 is not a limitation of the present invention.

It will be appreciated by those skilled in the art that the filter element mount 40 of the present invention can be manufactured in a conventional mount manufacturing manner, with the size of the filter element mount 40 being designed according to the size of the integral base 11. For example, the filter element mount 40 can be produced by injection molding, or can be produced in a combined manner, for example by adhesive bonding.

It should be noted that each part of the filter holder 40, that is, the filter holder main body 43, the inward extending arm 44, and the sinking arm 45, may be integrally formed of the same material, or may be made of different materials. In the drawings, for clarity of explanation, various components are shown with different line shading, but not limitation of material or structure.

It should also be noted that the filter mount 40 may be used to mount the filter element 50, and may also be used to mount the lens 30 or the actuator 60, and it should be understood by those skilled in the art that the mounting component on the filter mount 40 is not a limitation of the present invention.

As shown in fig. 7, is a first variant of the integrated base assembly and filter element mount according to the first preferred embodiment of the invention. In this embodiment, the integral base 11A extends obliquely upward inside to form the light window 111A with an opening gradually increasing. More specifically, the integrated base 11A has an inner side surface 114A, and the inner side surface 114A forms an inclined angle α with the central optical axis of the camera module 100, so that the opening of the optical window 111A is gradually enlarged, thereby facilitating the manufacturing and molding of the integrated base 11A. Wherein α ranges in size from 3 ° to 30 °, and in some embodiments, the value of α is selected from 3 ° to 15 °, 15 ° to 20 °, or 20 ° to 30 °. Accordingly, the engaging groove 42A of the filter element mount 40A has an engaging angle α 1, and the engaging angle α 1 corresponds to the inclination angle α, so that the shape of the engaging groove 42A is adapted to the inclination shape of the inner side surface 114A, so that the filter element mount 40A is more stably mounted.

In other words, the dip arm 45A extends obliquely downward from the filter element holder body 43A in a direction of rotation, so as to form the engagement angle α 1 corresponding to the inclination angle α. Further, in one embodiment, the inwardly extending arm 44A extends angularly and horizontally at the sunken arm 45A to form a support angle β, the support angle β being greater than 90 ° to facilitate mounting of the filter element 50. Of course, the filter element mount 40 without the engagement angle α 1 and the support angle β can also be mounted on the integrated base 11 with the inclination angle α.

Fig. 8A shows a second variant of the integrated base assembly and filter element mount according to the first preferred embodiment of the invention. The filter element mount 40B has a supporting slot 41B, and the supporting slot 41B is communicated with the optical window 111 of the integrated base 11B to provide an installation position for the filter element 50. In other words, the filter element 50 is mounted to the support groove 41B.

Further, the filter holder 40B includes a filter holder main body 43B and at least one inward extending arm 44B, and the inward extending arm 44B extends laterally and integrally inward from a lower portion of the filter holder main body 43B to form the supporting groove 41B. The filter element mount main body 43B is joined to the integrated base 11.

That is, the filter element mount 40B does not include the sinking arm 45 and does not have the engaging groove 42, and therefore, with respect to the above-described embodiment, the mounting position of the filter element 50 is not sunk in the optical window 111, but the area of the filter element 50 required can also be reduced by the extending distance of the inward extending arm 44B, and the filter element 50 is accommodated in the supporting groove 41B, so that the relative height of the filter element 50 and the filter element mount main body 43B is reduced.

Fig. 8B is a modified example of the second modified embodiment of the filter element mount according to the first preferred embodiment of the present invention. The filter element mount 40B1 has a support slot 41B1 and a mounting slot 48B1 that provide mounting locations for the lens 30 and the filter element 50, respectively.

Further, the filter element holder 40B1 includes a filter element holder main body 43B1 and at least one inward extending arm 44B1, and the inward extending arm 44B1 extends transversely and integrally inward from the lower portion of the filter element holder main body 43B1 to form the supporting groove 41B1 and the mounting groove 48B 1. The filter mount 40B1 also includes a lens portion 49B1, the lens portion 49B1 extending integrally upward from the filter mount body 43B1 to accommodate the lens 30. In this embodiment of the invention, the filter element 50 is mounted in a reverse manner to the inwardly extending arm 44B 1.

Further, in this embodiment of the invention, the lens portion 49B1 is flat and internally unthreaded and is adapted to receive an unthreaded lens 30.

That is, when the camera module 100 is a fixed-focus camera module, the lens 30 can be directly installed inside the filter lens holder 40B1, so as to limit the lens 30. In particular, the lens portion 49B1 has a gap between it and the lens 30 to facilitate installation and adjustment of the lens 30 before being secured in place.

Fig. 8C is another variant of the second variant of the filter element mount according to the first preferred embodiment of the invention. The filter element mount 40B2 has a support slot 41B2 and a mounting slot 48B2 that provide mounting locations for the lens 30 and the filter element 50, respectively.

Further, the filter element holder 40B2 includes a filter element holder main body 43B2 and at least one inward extending arm 44B2, and the inward extending arm 44B2 extends transversely and integrally inward from the lower portion of the filter element holder main body 43B2 to form the supporting groove 41B2 and the mounting groove 48B 2. The filter mount 40B2 also includes a lens portion 49B2, the lens portion 49B2 extending integrally upward from the filter mount body 43B2 to accommodate the lens 30. In this embodiment of the invention, the filter element 50 is mounted in a reverse manner to the inwardly extending arm 44B 2.

Further, in this embodiment of the present invention, the lens portion 49B1 has a threaded configuration therein adapted to receive the threaded lens 30.

That is, when the camera module 100 is a fixed-focus camera module, the lens 30 can be directly installed inside the filter lens holder 40B2, so as to limit the lens 30.

It should be noted that, the above two embodiments are only used as examples to illustrate possible modifications of the filter holder, and the lens 30 can be directly mounted inside the filter holders 40B1 and 40B2, but are not limited thereto.

Fig. 9A shows a third variant of the filter element mount according to the first preferred embodiment of the invention. In this embodiment, the filter element holder 40 has at least one corner opening 441C, and the corner opening 441C is disposed at a corner position of the filter element holder 40, so as to facilitate the installation of the filter element 50 and reduce edge shadows caused by sharp corners in the imaging of the camera module. More specifically, two adjacent inwardly extending arms 44C form a corner opening 441C, and the corner opening 441C extends outwardly so as to increase the luminous flux of the camera module at the corner position of the filter element holder 40. In other words, the corner opening 441C is formed to extend outward adjacent to the inwardly extending arm 44C, so as to increase the light flux of the filter element holder 40 at the position of the corner opening 441C and reduce the edge shadow.

Specifically, in one embodiment, the corner openings 441C may be expanded square corners, for example, but not limited to, four corresponding expanded square corners disposed at four corner positions of the filter element mount 40. In other embodiments, the corner opening 441C may be a circular corner to increase the light flux at the corner of the filter element mount 40. Of course, in some embodiments, the corner openings 441C may not be provided, and those skilled in the art should understand that the shape, number and position of the corner openings 441C are not a limitation of the present invention.

As shown in fig. 9B, is a modified embodiment of the first preferred embodiment according to the present invention. The filter mount 40 includes at least one retention bump 46P, the retention bump 46P extending at least partially, convexly upward from the top of the filter mount 40. Further, the limiting protrusion 46P extends upwards from the top surface of the filter element holder main body 43 at least partially and convexly, so as to limit the mounted element and prevent dust or light from entering the inside of the camera module. The position-limiting protrusion 46P limits the driver 60 or the lens 30 by way of example but not limitation. In particular, in one embodiment, the position-limiting protrusion 46P is disposed at the middle of the lens holder main body 43, and divides the top of the lens holder main body 43 into two parts, the outer side is used for mounting the driver 60, and the lens 30 is located at the inner side. In this manner, the stop projection 46P can position the driver 60, reducing the deflection of the driver 60. And the glue mounting the actuator 60 can be prevented from overflowing to the inside to contaminate the lens or the internal components during the assembly process. In particular, the stop projection 46P may be an annular projection, so as to position the actuator 60 as a whole, blocking the glue from overflowing to the inside.

It should be noted that in other embodiments of the present invention, the surface of the position-limiting protrusion 46P may be provided with threads to facilitate direct installation of the lens 30. And when the outer side of the limit projection 46P is provided with a thread, the lens 30 with a larger aperture is suitable.

Fig. 10A to 11 show a camera module and its integrated base assembly and filter element lens holder according to a second preferred embodiment of the present invention. The integrated base 11D includes a base body 112D forming at least one light window 111D for providing light path to the photosensitive element 20. Further, the base main body 112D has at least one opening 1121D, the opening 1121D communicates with the optical window 111D and the outside, and the filter element lens holder 40D is supplemented to the opening 1121D, so as to form the optical window 111D with a side surface closed.

In other words, in such an embodiment, the base body 112D is not in a closed configuration, but rather is in an open configuration, and the base body 112D is closed by the addition of the filter element mount 40D.

The filter lens mount 40D includes at least one extension leg 433D, and the extension leg 433D integrally extends from the filter lens mount main body 43D to the substrate 121, so as to close the opening 1121D. By way of example and not limitation, the extension legs 433D are attached to the base plate 121 and/or the base body 112 by bonding.

Specifically, the base body 112D forms a U-shaped structure, the filter lens holder body 43 is connected to the U-shaped structure of the base body 112D, and the extension leg 433D of the filter lens holder 40D is supplemented to the opening position of the U-shaped structure, so that the integrated base 11D is closed to form a closed internal environment.

In other words, in this embodiment, the integral base 11D and the filter element mount 40D share the function of the mount of the camera module, so that the advantages of integral packaging are combined with the function of the filter element mount 40D.

It is worth mentioning that, as the size requirement of the camera module is higher and higher, the arrangement of the electronic components 122 of the circuit board 12, the arrangement position of the electrical connection component 203, the packaging position of the integrated base 11, and the like need to be reasonably arranged, so that the occupied area of the component layout is the minimum while the substrate 121 is fully utilized, thereby further reducing the size of the camera module. According to this embodiment of the present invention, the electronic component 122 is integrally packaged in the direction in which the electronic component 122 is arranged, the electronic component 122 is encapsulated, the spatial position of the electronic component 122 is utilized, and the electromagnetic influence between the electronic component 122 and the electrical connection element 203 is reduced, whereas the extension leg 433D of the filter element holder 40D is provided on the side where the electronic component 122 is not provided, and the remaining position on the substrate 121 is fully utilized. On the other hand, through the bonding process of the filter element lens holder 40D, the flatness of the integrated base 11D can be adjusted and supplemented, and good installation conditions are provided for the camera module.

It should be further noted that the substrate 121 needs to be provided with the photosensitive element 20, the electronic component 122, the electrical connection element 203, the integrated base 11D, and the filter element lens holder 40D, and the electronic component 122, the electrical connection element 203, the integrated base 11D, and the filter element lens holder 40D are disposed around the photosensitive element 20. In other words, the substrate 121 has a plurality of mounting regions 1213, the mounting regions 1213 surrounding the outside of the photosensitive element 20. In order to improve the space utilization on the substrate 121, in some embodiments, the electronic components 122 are collectively disposed on the mounting area 1213 on one side or the mounting areas 1213 on both sides of the substrate 121, the mounting area 1213 on which the electronic components 122 are disposed is integrally packaged by the integral base 11D, and the electronic components 122 are covered by the integral base 11D, and the filter element mount 40D is connected to the area where the electronic components 122 are not disposed and/or the mounting area 1213 adjacent to the electrical connection element 203, so that the filter element mount 40D and the integral base 11D are matched and form the optical window 111D by the filter element mount 40D at a narrower position on the substrate 121, thereby providing a light path for the photosensitive element 20. That is, the photosensitive element 20 may not be disposed at the center of the substrate 121, but may be biased to one side to form the mounting regions 1213 of different widths, thereby facilitating the concentrated arrangement of the electronic components 122. Further, the extension leg 433D of the filter element lens holder 40D is connected to a narrower position where the electronic component 122 and the electrical connection element 203 are not disposed, and the wider mounting area 1213 mounts the electronic component 122 and the electrical connection element 203, and the integrated base 11D is integrally formed to cover the electronic component 122. For example, the widths of the two sides of the photosensitive element are W1 and W2, W1 is smaller than W2, the extension leg 433D of the filter element holder 40D is connected to the narrower W1 side, and the electronic component 122 is provided on the wider W2 side, so that the electronic component 122 is intensively provided on the wider side.

For example, but not limited to, in some embodiments, the assembly process of the integrated base assembly 10 may be to attach the photosensitive element 20 to the substrate 121, mount the mounting regions 1213 with different widths at the mounting position where the photosensitive element 20 is designed, such as adjacent to one side, then mount the electronic component 122 at the mounting regions 1213, such as the wider mounting regions, further integrally package the mounting regions 1213 with at least the electronic component to form the integrated base 11D, and then mount the filter element lens holder 40D to the integrated base 11D. In another embodiment, the electronic component 122 may be attached to the predetermined position, such as the predetermined mounting region 1213, and then the integrated base 11D is formed, and then the photosensitive element 20 is mounted.

It is also worth mentioning that the filter element mount 40D can be manufactured by injection molding, so that a smaller wall thickness can be obtained compared to the molding of the integrated base 11D, i.e. the thickness D1 of the extension leg of the filter element mount 40D can be smaller than the thickness D2 of the integrated base, so that the mounting areas 1213 of different widths of the substrate 121 can be more reasonably utilized.

As shown in fig. 12A to 13A, are variant embodiments of an integrated base assembly and filter element mount according to a second preferred embodiment of the present invention. The integrated base 11E includes a base main body 112E, and the base main body 112E forms at least one light window 111E for providing a light path for the light sensing element 20. Further, the integrated base 11E has two openings 1121E, each of the openings 1121E is communicated with the optical window 111E and the outside, and the filter element lens holder 40E supplements the two openings 1121E to close the side surface of the optical window 111E.

The filter element mount 40E includes two extension legs 433E, and each of the extension legs 433E integrally extends downward from the filter element mount main body 43E to the substrate 121, so as to close each of the openings 1121E. By way of example and not limitation, each of the extension legs 433E is connected to the base plate 121 and/or the base body 112E by bonding.

More specifically, in one embodiment, the base body 112E is a parallel structure, the filter element holder body 43E is coupled to the parallel structure of the base body 112E, and the extension leg 433E of the filter element holder 40E is complementary to the two open ends of the parallel structure, so that the base body 112E is closed to form a closed internal environment.

Fig. 13B and 13C show another variant of the integrated base assembly and filter element mount according to the second preferred embodiment of the present invention. In this embodiment, the integrated base 11Q includes a base main body 112Q, and the base main body 112Q forms at least one light window 111Q for providing a light path for the photosensitive element 20. Further, the integrated base 11Q has two openings 1121Q, each of the openings 1121Q is communicated with the optical window 111Q and the outside, and the filter element mount 40Q is supplemented to the two openings 1121Q to close the periphery of the optical window 111Q. Unlike the above embodiment, the two openings 1121Q are opposite and have an inverted trapezoid structure, so as to facilitate positioning and mounting of the filter element mount 40Q. In other words, the two openings 1121Q partition the base body 112Q into two opposite portions, and when the filter holder 40Q is mounted to the base body 112Q, the two portions of the base body 121Q are closed by the filter holder 40Q.

Accordingly, the filter element mount 40Q includes two extension legs 433Q, and each of the extension legs 433Q integrally extends downward from the filter element mount main body 43Q to the substrate 121, so as to close the opening 1121Q. Specifically, the two extending legs 433Q are disposed oppositely, and have an inverted trapezoid structure, which is suitable for being supplemented to the opening 1121Q. For example, when the filter element mount 40Q is mounted, the extension leg 433Q is limited to the opening 1121Q. That is, each of the openings 1121Q is gradually enlarged from bottom to top, and the extension leg 433Q is gradually widened from bottom to top to supplement the opening 1121Q, so that the opening 1121Q is closed.

It should be understood by those skilled in the art that the shape and size of the opening 1121Q in the embodiments of the present invention are only used as examples to illustrate the way that the present invention can be implemented, and are not limited thereto.

In particular, in some embodiments, the electronic components 122 may be collectively disposed on one side and covered by at least a portion of the base body 112Q and by the wider base body 112Q, while the side where the electronic components 122 are not disposed corresponds to the narrower base body 112Q. The filter mount 40Q is mounted on the base body 43Q, and the extension leg 433Q complements the opening 1121Q between the two portions.

Further, the base body 112Q has at least one opening surface 1122Q, and the opening 1121Q is formed opposite to the two opening surfaces 1122Q. The opening surface 1122Q integrally extends upward from the base plate 121 at an inclination so as to form the opening 1121Q of an inverted trapezoid. Accordingly, the extension leg 433Q has at least one complementary surface 4331Q, and the complementary surface 4331Q corresponds to the opening surface 1122Q, so that the extension leg 433Q is complementary to the opening 1121Q in shape, and the periphery of the optical window 111Q is closed. It is understood that a gap may exist between the supplemental face 4331Q of the extension leg 433Q and the opening face 1122Q of the opening 112Q to facilitate the application of an adhesive medium, such as glue, but the size or presence of the gap is not a limitation of the present invention.

In particular, the extension leg 433Q and the supplemental surface 4331Q and the open surface 1122Q of the base body 112Q may be fixed or sealed by gluing.

Fig. 14 shows a camera module, a base assembly and a filter holder according to a third preferred embodiment of the present invention. The integrated base 11F has a mounting groove 115F, and the mounting groove 115F is communicated with the optical window 111F. According to this embodiment of the present invention, the mounting groove 115F is an annular communicating groove, and the filter element mirror holder 40 is mounted to the mounting groove 115F.

Specifically, the engagement groove 42 of the filter element mount 40 is engaged with the mounting groove 115F of the integrated base 11F, so that the filter element mount main body 43 of the filter element mount 40 is supported to be accommodated in the groove 115F.

The filter holder body 43 of the filter holder 40 has a predetermined thickness so that it is not easily touched to an upper component such as the actuator 60 or the lens 30.

The photo sensor is mounted On the substrate 121 by, for example, but not limited to, a Surface Mount Technology (SMT), and is electrically connected to the substrate 121 by a cob (chip On board) gold wire bonding method. Of course, in other embodiments of the present invention, the photosensitive element 20 may be mounted on the substrate 121 in other manners, such as embedded, FC (Flip Chip), etc., and it should be understood by those skilled in the art that the connection and mounting manner of the photosensitive element 20 and the circuit board 12 is not limited by the present invention.

More specifically, the front surface 201 of the photosensitive element 20 has a photosensitive region 1311 and a non-photosensitive region 1312, and particularly, the non-photosensitive region 1312 surrounds the photosensitive region 1311. The photosensitive region 1311 is used for performing a photosensitive action to convert an optical signal into an electrical signal, and the non-photosensitive region 1312 is connected to the circuit board 12 through the electrical connection element 203 to transmit the electrical signal to the circuit board 12. The lens 30 is aligned with the photosensitive element 20, and the optical axes are the same, so that the light passing through the lens 30 can reach the photosensitive element 20 through the optical window 111, and further after photoelectric conversion of the photosensitive element 20, an electrical signal can be transmitted to the circuit board 12, so that the image information is collected by the camera module.

As shown in fig. 25A to 26, the single camera module 100 includes the filter element 50 for filtering the light passing through the lens 30. The filter element 50 is exemplified by, but not limited to, an infrared cut filter element 50, a blue glass filter. The filter element 50 is mounted on the filter element mount 40 and is located in a light path of the photosensitive element 20. The camera module unit 100 may further include a driver 60, such as a voice coil motor, a piezoelectric motor, etc. The lens 30 is mounted to the actuator 60 so as to form a moving focus camera module. The driver 60 includes at least one pin 61, and the driver 60 is operatively connected to the circuit board 12 through the pin 61. The pins 61 may be one of single pins, double pins, single row pins, or double row pins. In the drawings of the present invention, a two-pin is taken as an example for illustration, but not as a limitation. The leads 61 are generally located near the edges, as viewed from a position corresponding to the cross-center line in the position of fig. 26, corresponding to the cross-sectional views of fig. 25A and 25B, while the leads 61 are not actually visible in the cross-sectional views corresponding to fig. 25A and 25B, but for ease of understanding and explanation, the existence of the leads 61 is indicated by dashed lines in the corresponding cross-sectional views, not to indicate the actual positions of the leads 61, as is the case in the subsequent figures. It will be understood by those skilled in the art that the type, shape and placement of the pins 61 are not intended to be limiting.

As shown in fig. 25A to 27, the filter element 50 is mounted on the filter element mount 40 and is sunk in the optical window 111 of the integrated base 11. The unitary base 11 of the unitary base assembly 10 has a top surface 113, the filter mount 40 is mounted to the top surface 113 of the unitary base 11, and the actuator 60 is mounted to the filter mount 40. According to this embodiment of the invention, the top surface 113 of the integrated base 11 extends planarly, in other words, the integrated base 11 forms a platform structure, without step projections, to which the filter element mount 40 is mounted. It is worth mentioning that in this manner, the top surface 113 of the integrated base 11 extends planarly without significant bending angles, so that a more even and burr-free mounting surface can be obtained during the integrated packaging process, such as molding, to provide a flat mounting condition for the filter element lens holder 40.

Further, the filter element mount 40 has a supporting groove 41 and an engaging groove 42, the supporting groove 41 is used for mounting the filter element 50, and the engaging groove 42 is used for mounting on the integrated base 11. The supporting slot 41 is connected to the light window 111 to form an accommodating opening 411 for accommodating the filter element 50. The engaging groove 42 surrounds the periphery of the filter element mount 40.

Further, the filter holder 40 includes a filter holder main body 43, at least one inwardly extending arm 44, and at least one depressed arm 45, and the depressed arm 45 extends integrally from the filter holder main body 43 in a turning and longitudinal direction so that the installation position of the filter is depressed into the optical window 111. The inward extending arm 44 is bent and transversely integrally extended from the sinking arm 45 so as to provide a horizontal installation position for the filter element 50, so that the optical axes of the filter element 50 and the photosensitive element 20 are consistent. In particular, the filter element mount 40 includes four integrally connected inwardly extending arms 44 and four integrally connected downwardly depending arms 45, each of the inwardly extending arms 44 and each of the downwardly depending arms 45 extending at different locations to form the annular integral filter element mount 40.

In one embodiment, the engaging groove 42 of the filter element mount 40 has a shape corresponding to the shape of the optical window 111 formed by the integrated base 11, and the supporting groove 41 has a shape corresponding to the shape of the filter element 50. In particular, the filter element 50 has a square structure, and the supporting groove 41 has a ring shape, such as a square ring shape, in a top view.

It is worth mentioning that the extension distance of the sinking arm 45 affects the sinking depth of the filter in the light window 111, and the extension distance of the inward-extending arm 44 affects the size of the area of the filter to be installed. For example, when the sinking arm 45 extends a greater distance, the filter sinks in the light window 111 more, the distance from the light sensing element 20 is smaller, and the back focal length of the corresponding image capturing module unit is smaller; when the extending distance of the inner extending arm 44 is longer, the smaller the accommodating opening 411 of the filter element lens holder 40 is, the smaller the area of the filter element 50 is required to be, so that the filter element 50 is more suitable to be obtained, the installation is convenient, and the cost of the single camera module is reduced. Certainly, the extending distance of the sinking arm 45 needs to be combined with the imaging effect of the camera module, for example, dark spots such as dust images are not generated on the basis of reducing the back focus; the extending distance of the inner extending arm 44 needs to consider factors such as the light path of the camera module, the photosensitive region 1311 and the non-photosensitive region 1312 of the photosensitive element 20, and the remaining width of the circuit board 12, for example, when the inner extending arm 44 extends inward, the inner extending arm 44 does not block the photosensitive region 1311 of the photosensitive element 20 and does not block the incoming light flux too much under the condition that the filter element 50 is small, and the inner extending arm can extend more at the position where the package of the circuit board 12 is wide and extend less at the position where the package of the circuit board 12 is small, so that the area of the filter element 50 is reduced as much as possible under the condition that the imaging quality is ensured.

For example, referring to fig. 25B, the distance between the inwardly extending arms 44 on opposite sides is marked as L, and the diameter of the filter element 50 only needs to be larger than L, so that the filter element 50 can be mounted on the inwardly extending arms 44 without being mounted on the base main body 112, thereby reducing the required area of the filter element 50.

The shape of the filter element mount 40 is matched to the shape of the integral base 111A. In some embodiments, the integral base 11 is approximately regular symmetrical, such as a square ring, and accordingly, the filter element mount 40 is symmetrical, the filter element mount body 43 is regular, the inwardly extending arms 44 are uniform, and the downwardly extending arms 45 are uniform. In other embodiments, because the electronic component 122 to be encapsulated is located at a different position, the interior of the integrated base 11 has an inward protruding position and a different width, and accordingly, the filter element mount body 43 may be provided with a corresponding groove or protruding position, or the lengths of the inner extending arms 44 are different to adapt to the shape of the integrated base 11, the position of the photosensitive element 20, and the installation of the filter element 50 is facilitated.

In some embodiments, the filter element mount 40 may be mounted on the integrated base 11A by means of glue bonding, and the flatness of the filter element mount 40 may be adjusted by the thickness of the glue.

Furthermore, the two camera module single bodies are connected in a connected mode to form an array structure. Specifically, the two integrated base assemblies 10 of the two camera module units 100 are connected to form a connected base assembly 1100. Two of the circuit boards 12 are integrally connected to form a one-piece circuit board 1120. The two integrated bases 11 are integrally connected to form an integrated base 1110. The two filter element lens mounts 40 are connected together to form a connected filter element lens mount 1400. That is, the connected base 1110 formed in the integrated packaging process forms two light windows 111 to provide light paths for the two photosensitive elements 20, respectively. Alternatively, the two filter element mounts 40 may be separate mounts that are not integrally connected and are separately mounted to the conjoined base 1110. The two integral bases 11 may also be two separate bases.

Specifically, the connected base 1110 is integrally packaged in the connected circuit board 1120, and the connected base 1110 has two light windows 111 for providing light paths for the two photosensitive elements 20 and the lens 30, respectively. The conjoined filter element lens base 1400 has two support grooves 41 for mounting the filter element 50, respectively.

It should be noted that the two camera module single bodies 100 are integrally arranged, which is helpful to improve the consistency of the two camera module single bodies 100 and save space. For example, the one-piece filter element mount 1400 may provide mounting locations for two filter elements 50 at the same time, and during the manufacturing process, the uniformity of the two supporting slots 41 may be controlled by the area, so as to provide a uniform mounting environment for the filter elements 50.

The integrated base 1110 includes an integrated portion 1111, and the integrated portion 1111 integrally connects adjacent integrated bases 11. The conjoined filter element mount 1400 includes a bridging portion 1410, and the bridging portion 1410 integrally connects the two filter element mounts 40 and is adapted to bridge the conjoined portion 1111 of the conjoined base 1110. More specifically, two adjacent sides of the base main body 112 of the two integrated bases 11 are integrally connected to form the integrated part 1111. Two adjacent sides of the filter element holder main body 43 of the two filter element holders 40 are integrally connected to form the bridging portion 1410.

It should be noted that, in this embodiment of the present invention, referring to fig. 25A and 25B, both of the camera module units 100 include the driver 60, that is, both of the camera module units 100 are moving-focus camera modules, and the two moving-focus camera modules cooperate with each other to acquire an image. In other embodiments of the present invention, the array camera module 1000 may also be a combination of other types of camera module monomers. In an embodiment, referring to fig. 28A and 28B, neither of the two single camera modules 100 includes the driver 60, that is, both of the two single camera modules 100 are fixed-focus camera modules, and the two fixed-focus camera modules cooperate with each other to acquire an image. In an embodiment, referring to fig. 29A and 29B, one single camera module 100 of the array camera module 1000 includes one driver 60 to form a moving-focus camera module, and the other single camera module 100 does not include the driver 60 to form a fixed-focus camera module, where the moving-focus camera module and the fixed-focus camera module cooperate to acquire an image.

In this embodiment, the integral filter element mount 1400 is mounted to the integral base 1110 and each of the actuators 60 is mounted to the integral filter element mount 1400, i.e., the integral filter element mount 1400 is disposed between the actuator 60 and the integral base 1110. In yet another alternative embodiment, referring to FIGS. 30A and 30B, both the unitary base 1110 and the driver 60 are mounted to the top surface 113 of the unitary base 1110. Further, the unitary filter mount 1400 is mounted adjacent to the inside of the unitary base 11 and the actuator 60 is mounted adjacent to the outside of the unitary base 1110 such that the actuator 60 and the unitary filter mount 1400 cooperate to dispense the top surface 113 of the unitary base 1110.

As shown in fig. 31, is a first variant embodiment of a unitary base and a unitary filter element mount according to an eleventh preferred embodiment of the present invention. In this embodiment, each of the integrated bases 11A extends obliquely upward inside to form the light window 111A whose opening gradually increases. More specifically, each of the integrated bases 11A has an inner side surface 114A, and the inner side surface 114A forms an inclined angle α with the central optical axis of the camera module, so that the opening of the optical window 111A is gradually enlarged, thereby facilitating the manufacturing and molding of the integrated base 11A. Wherein α ranges in size from 3 ° to 30 °, and in some embodiments, the value of α is selected from 3 ° to 15 °, 15 ° to 20 °, or 20 ° to 30 °. Accordingly, the engaging groove 42A of each filter element mirror holder 40A has an engaging angle α 1, and the engaging angle α 1 corresponds to the inclination angle α, so that the shape of the engaging groove 42A is adapted to the inclined shape of the inner side surface 114A, so that the filter element mirror holder 40A is more stably mounted.

In other words, the dip arm 45A extends obliquely downward from the filter element holder body 43A in a direction of rotation, so as to form the engagement angle α 1 corresponding to the inclination angle α. Further, in one embodiment, the inwardly extending arm 44A extends angularly and horizontally at the sunken arm 45A to form a support angle β, the support angle β being greater than 90 ° to facilitate mounting of the filter element 50. Of course, the filter element mount 40A without the joining angle α 1 and the supporting angle β may be mounted on the integrated base 11A with the inclination angle α.

FIG. 32A shows a second variant embodiment of a unitary base assembly and a unitary filter element mount according to an eleventh preferred embodiment of the present invention. Each of the filter element lens holders 40B has a supporting groove 41B, and the supporting groove 41B communicates with the corresponding optical window 111B of the integrated base 11B to provide an installation position for the filter element 50. In other words, the filter element 50 is mounted to the support groove 41B.

Further, the filter holder 40B includes a filter holder main body 43B and at least one inward extending arm 44B, and the inward extending arm 44B extends laterally and integrally inward from a lower portion of the filter holder main body 43B to form the supporting groove 41B. The filter element mount main body 43B is joined to the integrated base 11B.

That is, the filter element mount 40B does not include the sinking arm 45 and does not have the engagement slot 42, and thus the mounting position of the filter element 50 is not sunk in the optical window 111B, as compared to the above embodiment. However, the required area of the filter element 50 can also be reduced by the extension distance of the inwardly extending arms 44B.

FIG. 32B is a modified example of a second modified embodiment of a one-piece filter element mount according to an eleventh preferred embodiment of the present invention. Each of the filter element mounts 40B1 has a support slot 41B1 and a mounting slot 48B1 that provide mounting locations for the lens 30 and the filter element 50, respectively.

Further, each of the filter element mirror bases 40B1 includes a filter element mirror base main body 43B1 and at least one inward extending arm 44B1, and the inward extending arm 44B1 integrally extends inward in a transverse direction from a lower portion of the filter element mirror base main body 43B1 to form the supporting groove 41B1 and the attaching groove 48B 1. The filter mount 40B1 also includes a lens portion 49B1, the lens portion 49B1 extending integrally upward from the filter mount body 43B1 to accommodate the lens 30. In this embodiment of the invention, the filter element 50 is mounted in a reverse manner to the inwardly extending arm 44B 1.

That is, when the camera module unit 100B1 is a fixed focus camera module, the lens 30 can be directly mounted inside the filter holder 40B1, so as to limit the position of the lens 30. In particular, the lens portion 49B1 has a gap with the lens 30 to facilitate mounting and adjustment of the lens 30.

FIG. 32C is another variation of the second variation of the integral filter element mount according to the eleventh preferred embodiment of the present invention. Each of the filter element mounts 40B2 has a support slot 41B2 and a mounting slot 48B2 that provide mounting locations for the lens 30 and the filter element 50, respectively.

Further, each of the filter element mirror bases 40B2 includes a filter element mirror base main body 43B2 and at least one inward extending arm 44B2, and the inward extending arm 44B2 integrally extends inward in a transverse direction from a lower portion of the filter element mirror base main body 43B2 to form the supporting groove 41B2 and the attaching groove 48B 2. The filter mount 40B2 also includes a lens portion 49B2, the lens portion 49B2 extending integrally upward from the filter mount body 43B2 to accommodate the lens 30. In this embodiment of the invention, the filter element 50 is mounted in a reverse manner to the inwardly extending arm 44B 2.

That is, when the camera module unit 100B2 is a fixed focus camera module, the lens 30 can be directly mounted inside the filter holder 40B2, so as to limit the position of the lens 30.

It should be noted that the above two embodiments are only illustrative of possible modifications of the filter lens holder 40, and the lens 30 can be directly mounted inside the filter lens holders 40B1 and 40B2, but are not limited thereto.

As shown in fig. 33A, it is a third modified embodiment of the array camera module according to the eleventh preferred embodiment of the present invention. In this embodiment, each of the filter element lens holders 40C has at least one corner port 441C, and the corner port 441C is disposed at a corner position of the filter element lens holder 40, so as to facilitate installation of the filter element 50 and reduce edge shadows caused by sharp corners in imaging by the camera module. More specifically, two adjacent inwardly extending arms 44C form a corner opening 441C, and the corner opening 441C extends outwardly so as to increase the luminous flux of the camera module at the corner position of the filter element holder 40C.

Specifically, in one embodiment, the corner openings 441C may be expanded square corners, such as, but not limited to, four corresponding expanded square corners disposed at four corner locations of the filter element mount 40C. In other embodiments, the corner opening 441C may also be rounded to increase the light flux at the corner of the filter element mount 40C. Of course, in some embodiments, the corner openings 441C may not be provided, and those skilled in the art will appreciate that the shape, location and number of the corner openings 441C are not limitations of the present invention.

As shown in fig. 33B, is a modified embodiment of the eleventh preferred embodiment according to the present invention. In this embodiment of the present invention, each of the filter lens holders 40P includes a limiting protrusion 46P, and the limiting protrusion 46P extends upward from the top surface of the filter lens holder main body 43P at least partially and convexly, so as to limit the mounted components and prevent dust or light from entering the camera module. The position-limiting protrusion 46P limits the driver 60 or the lens 30 by way of example but not limitation. In particular, in this embodiment of the present invention, the integral filter element mount 1400P includes two of the limiting protrusions 46P, each forming an annular protrusion for limiting the corresponding actuator 60. In another embodiment, the bridging portion 1410P may be provided with the limiting protrusion 46P only around the connected filter element lens holder 1400P without the limiting protrusion 46P at the middle portion of the connected filter element lens holder 1400P formed by the two filter element lens holders 40P.

In this embodiment of the present invention, the stopper projection 46P can position the actuator 60, reduce the offset of the actuator 60, and prevent the glue mounting the actuator 60 from overflowing to the inside to contaminate the lens 50 or internal components during the assembly process.

As shown in fig. 34A to 35, the present invention is an array camera module according to a twelfth preferred embodiment of the present invention. Each of the integrated bases 11D includes a base body 112D forming at least one light window 111D for providing a light path for the photosensitive element 20. Further, the base main body 112D has at least one opening 1121D, the opening 1121D communicates the optical window 111D and the outside, and the filter element lens holder 40D is supplemented to the opening, so as to form the optical window 111D with a side surface closed.

Each of the filter lens mounts 40D includes at least one extension leg 433D, and the extension leg 433D integrally extends from the filter lens mount main body 43D downward to the substrate 121D so as to close the opening 1121D. By way of example and not limitation, the extension legs 433D are attached to the base plate 121D and/or the base body 112D by bonding.

The base body 112D forms a U-shaped structure, the filter element holder body 43D is joined to the U-shaped structure of the base body 121D, and the extension leg 433D of the filter element holder 40D is supplemented to the opening position of the U-shaped structure, so that the integrated base 11D is closed to form a closed internal environment.

It is worth mentioning that, as the size requirement of the camera module is higher and higher, the arrangement of the electronic components 122D on the circuit board 12D, the arrangement position of the electrical connection component 203, the packaging position of the integrated base 11D, and the like need to be reasonably arranged, so that the occupied area of the component layout is the minimum while the substrate 121D is fully utilized, thereby further reducing the size of the camera module. In contrast, according to this embodiment of the present invention, the electronic component 122D is integrally packaged in the direction in which the electronic component 122D is arranged, the electronic component 122D is covered, the electromagnetic influence between the electronic component and the electrical connection element 203 is reduced while utilizing the spatial position of the electronic component, and the filter holder 40D is provided in a manner in which the electronic component is not provided, and the remaining position on the substrate 121D is fully utilized. On the other hand, through the bonding process of the filter element lens holder 40D, the flatness of the integrated base 11D can be adjusted and supplemented, and good installation conditions are provided for the camera module.

Fig. 36A to 36C show modified embodiments of the conjoined base and the conjoined filter element lens holder of the array camera module according to the twelfth preferred embodiment of the present invention. The integrated base 11E includes a base main body 112E, and the base main body 112E forms at least one light window 111E for providing a light path for the light sensing element 20. Further, the integrated base 11E has two openings 1121E, each of the openings 1121E is communicated with the optical window 111E and the outside, and the filter element lens holder 40E supplements the two openings 1121E to close the side surface of the optical window 111E.

The filter element holder 40E includes two extension legs 433E, and each of the extension legs 433E integrally extends downward from the filter element holder main body 43E to the substrate 121E so as to close each of the openings. By way of example and not limitation, each of the extension legs 433E is connected to the base plate 121E and/or the base body 112E by bonding. More specifically, in one embodiment, the base body 112E is a parallel structure, the filter element mount 40E is coupled to the parallel structure of the base body 112E, and the extension legs 433E of the filter element mount 40E are complementary to the two open ends of the parallel structure, so that the base body 112E is closed to form a closed internal environment. In some embodiments, two adjacent extension legs 433E are integrally connected to form a common extension leg, i.e., a common leg. In particular, the common leg is spaced apart from the two optical windows 111E, and isolates the light paths of the two camera module units. That is, in this embodiment, the conjoined filter element mount 1400E includes three of the extension legs 433E, which are arranged in parallel, wherein the extension leg 433E in the middle separates two of the optical windows 111E, and the other two of the extension legs 433E respectively supplement the openings 1121E of the conjoined base 1110E, thereby forming two closed and independent optical windows 111E. In other words, in the array camera module 1000E, the two optical windows 111E of the two camera module units 100E are communicated with each other, and the conjoined base 1110E is supplemented by the conjoined filter element lens holder 1400E, so as to form two separated and closed optical windows 111E. And the adjacent extension legs 433E of the filter element mount 40E form a common portion instead of the link portion 1111E of the link base 1110E. In one embodiment, two adjacent extension legs 433E are integrally connected.

As shown in fig. 37A and 37B, is another variant embodiment of the unitary base assembly and filter element mount according to the twelfth preferred embodiment of the present invention. In this embodiment, each of the integrated bases includes a base body 112Q, and the base body 112Q forms at least one light window 111E for providing a light path for the photosensitive element 20. Further, the integrated base 11Q has at least one opening 1121Q, each of the openings is communicated with the optical window 111Q and the outside, and the filter element lens holder 40Q is supplemented to the opening 1121Q to close the periphery of the optical window 111Q. Unlike the above embodiments, in the integrated base assembly 1100Q, the two openings 1121Q of the two integrated base bodies 112Q are opposite to each other, so as to facilitate the position limitation of the integrated filter element lens holder 1400Q from two sides.

Further, each of the openings 1121Q has an inverted trapezoidal structure, so as to facilitate positioning and mounting of the filter element mount 40Q. Accordingly, the filter element holder includes at least one extending leg 433Q, and each of the extending legs 433Q integrally extends from the filter element holder main body 43Q to the substrate 121, so as to close the opening 1121Q. Specifically, the two extending legs 433Q are disposed oppositely, and have an inverted trapezoid structure, which is suitable for being supplemented to the corresponding opening 1121Q. For example, when the filter element mount 40Q is mounted, the extending legs are limited in the openings 1121Q, and respectively enclose the two optical windows 111Q.

In particular, in some embodiments, the electronic component 122Q may be collectively disposed on one side and covered by at least a portion of the base body 112Q and by a wider base body 112Q, while the side where the electronic component 122Q is not disposed corresponds to the narrower base body 112Q. The filter mount is mounted 40Q to the base body 43Q, and the extension leg 433Q complements the opening 1121Q between the two portions.

Further, the base body 112Q has at least one opening surface 1122Q, and the opening 1121Q is formed opposite to the two opening surfaces. The opening surface 1121Q integrally extends upward from the base plate 121 at an inclination so as to form the trapezoidal opening 1121Q. Accordingly, the extension leg 433Q has at least one complementary surface 4331Q, and the complementary surface 4331Q corresponds to the opening surface 1122Q, so that the extension leg 433Q is complementary to the opening 1121Q in shape, and the periphery of the optical window 111Q is closed.

Specifically, the extension leg 433Q and the supplement surface 4331Q and the opening surface 1122Q of the base main body 112Q may be fixed by gluing.

As shown in fig. 38A to 39, the present invention is an array camera module according to the thirteenth preferred embodiment of the present invention. Each of the integrated bases 11F has a mounting groove 115F and at least one notch 117F, and the mounting groove 115F is communicated with the optical window 111F. In this embodiment of the present invention, the notch 117F is disposed at a position adjacent to the two integrated bases, i.e., above the connection portion 1111F of the one-piece base 1110F, and is communicated with both sides. That is, the gap 117F communicates with the two mounting grooves 115 to accommodate the bridging portion 1410F of the conjoined filter element lens holder 1400F.

Each of the filter element mirror bases 40F is mounted to the mounting groove 115F. More specifically, the mounting groove 115F is a U-shaped groove, and the U-shaped opening corresponds to the notch 117F. In particular, the U-shaped grooves of the filter element mounts 40F are butted to form an internally connected closed structure. When the integrated filter lens holder 1400 is mounted on the integrated base 1110, the bridging portion 1410 of the integrated filter lens holder 1400 bridges the gap 117F located in the middle.

Specifically, the engagement groove 42F of the filter element mount 40F is engaged with the attachment groove 115F of the integrated base 111F, so that the filter element mount main body 43F of the filter element mount 40F is supported in the support groove 41F.

The filter holder body 43F of the filter holder 40F has a predetermined thickness so that it is not easily touched to an upper component such as the actuator 60 or the lens 30. Preferably, when the filter element mount 40F is mounted in the mounting groove 115F, the top surface of the filter element mount 40F and the top surface of the base main body 112F are coincident, so that the filter element mount 40F does not or less protrude from the base main body 112F and does not easily touch the driver 60 or the lens 30 located above.

More specifically, each of the integrated bases 11F includes a plurality of protruding steps 116F protruding from the base main body 112F. Each of the protruding steps 116F extends upward partially from the base main body 112F to form the mounting groove 115F. At least one side of the integrated base 11F does not have the raised step 116F, forming the notch 117F.

According to this embodiment of the present invention, each of the integrated bases 11F includes three raised steps 116F, and the raised steps 116F are turnably integrally connected to form the mounting groove 115F in a U shape. That is, the side without the raised step 116F forms the notch 117F.

In other words, the extended edge 432F extends into the gap 117F such that the gap 117F is filled, thereby forming a closed internal environment. In this embodiment, the extending edge 432F forms the bridge 1410F.

According to this embodiment of the present invention, the filter holder main body 43F of the filter holder 40F includes three joining sides 431F and one extending side 432F, and each of the joining sides 431F and the extending side 432F is turnably integrally connected so as to be adapted to the shape of the mounting groove 115F.

The sinking arm 45F is turned integrally downward from the engaging edge 431F and the extending edge 432F, respectively, to form the engaging groove 42F. The inwardly extending arm 44F extends laterally in one piece from the inwardly extending arm 44F in a turned manner, thereby forming the support groove 41F.

It is worth mentioning that the electronic component 122F is disposed at different positions of the main body of the circuit board 12F, and the integrated base 11F covers the electronic component 122F. At the position where the electronic component is arranged, the thickness required by the integrated base 11F is large, and the mounting groove 115F is conveniently provided, but the position without the electronic component 122F can be provided with a small thickness, so that the size of the circuit board 12F is reduced, and the mounting groove 115F is not suitable to be provided. According to this embodiment of the present invention, the electronic component 122F is disposed on the integrated base 11F corresponding to three of the joining edges 431F, the integrated base 11F has a larger lateral thickness, the mounting groove 115F is provided, and the integrated base 11F on the side corresponding to the extended edge 432F has a smaller lateral thickness, the mounting groove 115F is not provided, and the notch 117F is filled with the extended edge 432F, and plays a role of the protruding step 116F.

The actuator 60 is at least partially mounted to the raised step 116F to form a moving focus camera module. The driver 60 is operatively connected to the circuit board 12 by at least one pin 61. In other embodiments, the lens 30 is mounted on the raised step 116F or the filter mount 40F to form a fixed focus camera module.

More specifically, three sides of the actuator 60 are mounted to the raised step 116F, while the remaining side is mounted to the extended side 432F of the filter mount 40F. In some embodiments, there is a gap between the driver 60 and the extended edge 432F, and the gap is sealed with glue to form a closed internal environment for the camera module. In other words, the surface height of the extended edge 432F is lower than the surface height of the raised step 116F, and the height difference can be supplemented by glue. Specifically, the actuator 60 may be mounted to the protruding step 116F by bonding, and make the optical axes of the lens 30 and the photosensitive element 20 coincide.

As shown in fig. 40A to 41, the present invention is an array camera module according to a fourteenth preferred embodiment of the present invention.

Each of the integrated bases 11R includes a base main body 112R forming at least one light window 111R for providing a light path for the photosensitive element 20. Further, the base main body 112R has at least one opening 1121R, the opening 1121R communicates with the optical window 111R and the outside, and the filter element lens holder 40R is supplemented to the opening, so as to form the optical window 111R with a side surface closed. In this embodiment, the two openings 1121R of the two integrated bases 11R of the one-piece base 1110R communicate with each other.

Each of the filter lens mounts 40R includes at least one extension leg 433R, and the extension leg 433R integrally extends from the filter lens mount main body 43R downward to the substrate 121R so as to close the opening 1121R. By way of example and not limitation, the extension legs 433R are connected to the base plate 121R and/or the base body 112R by bonding.

In some embodiments, two adjacent extension legs 433R are integrally connected to form a common extension leg, i.e., a common leg, and particularly, the common leg is spaced apart from the two optical windows 111R to isolate the light paths of the two camera modules. That is, in this embodiment, the conjoined filter element mount 1400R includes two integrally connected extending legs 433R located in the middle of the two middle light windows 111R to separate the two light windows 111R, thereby forming two closed and independent light windows 111R.

The integrated base 11R has at least one mounting groove 115R and an opening 117R, the mounting groove 115R communicates with the optical window 111R, and the opening 117R communicates with the optical windows 111R on both sides. The filter element mount 40R is mounted to the mounting groove 115R.

That is, in this embodiment, the notches 117R of the one-piece bases are disposed at adjacent positions of two of the one bases 11R, and communicate with each other. The extended edges 432R of the conjoined filter element lens base are arranged at corresponding adjacent positions and integrally connected to form the bridging portion 1410R.

The sinking arm 45R is formed to be turned from the coupling rim 431R to integrally extend downward to form a coupling groove 42R so as to be coupled to the mounting groove 115R. The inwardly extending arm 44R is formed to extend laterally and integrally with the support groove 41R in a direction turned from the depressed arm 45R so as to provide a mounting position for the filter element 50. It is worth mentioning that the electronic component 122R is disposed at different positions of the circuit board main body 121R, and the integrated base 11R covers the electronic component 122R. At the position where the electronic component is arranged, the thickness required for the integrated base 11R is large and is convenient for forming the mounting groove 115R, and the position without the electronic component 122R can be set to a small thickness, thereby reducing the size of the circuit board 12R and being unsuitable for forming the mounting groove 115R. According to this embodiment of the present invention, the electronic component 122R is arranged on the integrated base 11R corresponding to the two joining edges 431R, the lateral thickness of the integrated base 11R is larger, the mounting groove 115R is provided, and the lateral thickness of the integrated base 11R on the side corresponding to the raised step 116R where the mounting groove 115R is not formed is smaller.

The actuator 60 is at least partially mounted to the raised step 116R to form a moving focus camera module. The driver 60 is operatively connected to the circuit board 12R via at least one of the pins 61. In other embodiments, the lens 30 is mounted on the raised step 116R or the filter holder 40R to form a fixed focus camera module.

More specifically, the driver 60 is mounted to the raised step 116R, wherein two sides are supported to the raised step 116R where the mounting groove 115R is formed, while the remaining one side is mounted to the raised step 116R where the mounting groove 115R is not formed, and the remaining one side is supported to the extended side 432R.

The adjacent position of the two integrated bases 11H does not include the raised step 116H, forming a gap 117H. That is, the connected base 1110H forms two parallel mounting grooves 115H, and the gap 117H is located between the two mounting grooves 115H. Accordingly, each of the filter element lens holders 40H forms a U-shaped structure, and an opening of the U-shaped structure is opposite to the protruding step 116H where the mounting groove 115H is not formed. That is, the integral filter lens holder 1400H is viewed as an E-shaped structure in plan, the middle portion of the E-shaped middle structure is bridged over the connecting portion 1111H of the connecting base 1110H, and the openings at the two ends are blocked by the protruding step 116H.

In the integral filter element lens base 1400I, two adjacent extension edges 432I are integrally connected to form the bridging portion 1410I, which is adapted to the connecting portion 1111I of the integral base 1110I. According to another variant embodiment, the two raised steps 116I of the integral base 11I are adjacent to the two joining edges 431I, and the two notches 117I are adjacent to each other. That is, the two protruding steps 116I form an L-shaped structure, so as to form an L-shaped mounting groove 115I. The notches 117I are adjacent to each other, thereby forming an L-shaped extension. Accordingly, the two joining edges 431I of the filter lens holder 40I are adjacent and adapted to be joined to the L-shaped mounting groove 115I, and the two extending edges 432I are adjacent and adapted to fill the L-shaped gap 117I, thereby forming a closed inner environment.

As shown in fig. 46A and 47, a modified embodiment of the array camera module according to the fifteenth preferred embodiment of the present invention is shown. In this embodiment of the present invention, the position where the raised step 116J is provided is different from the above-described preferred embodiment. In the connected base 1110J of the array camera module, the protruding steps 116J of the two integrated bases 11J are opposite to each other to form a parallel structure, and each protruding step 116J and the corresponding base main body 111 form the mounting groove 115J. That is, the two mounting grooves 115J on the connected base 1110J are disposed at opposite positions to each other. In contrast to the fifteenth embodiment, in this modified embodiment, the two raised steps 116J of the connected base 1110J are changed from a straight arrangement to a relatively parallel arrangement.

As shown in fig. 48A, 48B and 49, it is an implementation of the array camera module according to the sixteenth preferred embodiment of the present invention. Unlike the preferred embodiment, each of the integral bases 11K includes one raised step 116K and has three notches 117K. The raised step 116K extends partially and integrally upward from the base main body 112K to form the mounting groove 115K. That is, the notch 117K is formed on three sides without the raised step 116K.

According to this embodiment of the present invention, the filter holder main body 43K of the filter holder 40K includes an engaging edge 431K and three extending edges 432K, and each of the engaging edge 431K and the extending edges 432K is turnably integrally connected so as to be adapted to the shape of the mounting groove 115K and the notch 117K. The two adjacent extending edges 432K are integrally connected to form the bridging portion 1410K of the connected filter element lens holder 1400, and bridge the connecting portion 1111K of the connected base 1110K.

In other embodiments, the lens 30 is mounted on the raised step 116K or the filter holder 40K to form a fixed focus camera module.

It should be noted that in this embodiment of the present invention, the two raised steps 116K of the two integrated bases 11K are offset in parallel, so as to limit the installation position of the conjoined filter element lens holder 1400, and in other embodiments of the present invention, the relative position of the raised steps 116K may be in other layouts, for example, in parallel or perpendicular directions. It should be understood by those skilled in the art that the layout structure of the two raised steps 116K is not a limitation of the present invention.

As shown in fig. 50A to 51, it is an array camera module according to the seventeenth preferred embodiment of the present invention. Unlike the preferred embodiment, each filter element mount 40L includes an upper extension wall 46, and the upper extension wall 46 extends upwardly and rotatably from the filter element mount body 43L to form a limiting opening 461L. The position-limiting opening 461L is used for limiting the mounted components, such as but not limited to the driver 60 and the lens 30. That is, when the array camera module 1000L is assembled, each of the drivers 60 or the lenses 30 is installed in the position-limiting opening 461L of each of the filter element lens holders 40L, and the drivers 60 or the lenses 30 are limited, so that the optical axes of each of the drivers 60 or each of the lenses 30 and each of the photosensitive elements 20 coincide with each other. The size of the limiting opening 461L may be determined according to the size of the component to be mounted.

In other words, the extending wall 46L has a frame restraining function, so that when the components such as the actuator 60 or the lens 30 are mounted on the filter holder 40L, excessive deviation is not generated, and the consistency of the optical system of the camera module is ensured. Meanwhile, the upper extension wall 46L may shield a mounted component, such as the driver 60 or the lens 30, from an external unnecessary touch, so that the driver 60 or the lens 30 is stably mounted. And can shield external dust from entering the interior of each of the camera module units 100L.

Further, when the camera module unit 100L is a moving focus camera module, the filter lens holder 40L has at least one pin hole 462L for passing through the pin 61. That is, when the driver 60 is mounted in the position-limiting opening 461L of the filter lens holder 40L, the pins of the driver 60 pass through the pin openings 462L and are electrically connected to the circuit board 12L. Of course, when the camera module unit 100L is a fixed-focus camera module, the filter lens holder 40L may not be provided with the pin port 462L.

It should be noted that the pin opening 462L may not be visible in the actual sectional view, but for convenience of illustration and understanding, the pin opening 462L is illustrated in the figure by a dotted line, and the position is not limited to the corresponding actual arrangement position.

It should be noted that the driver 60 or the lens 30 of the array camera module 1000L is limited by the extending wall 46L, which helps to restrict the consistency of the optical axes of the camera module units 100L, and simultaneously facilitates control of the consistency of the camera module units 100L.

Unlike the preferred embodiment, each filter lens holder 40M includes an upper extension wall 46M and a lower extension wall 47M, the upper extension wall 46M extends upward from the filter lens holder main body 43M in a direction opposite to the direction of rotation to form a retaining opening 461M, and the lower extension wall 47M extends downward from the filter lens holder main body 43M in a direction opposite to the direction of rotation to form a bag-in opening 471M. In particular, the lower extension wall 47M extends integrally from the upper extension wall 46M to form an integral outer abutment wall.

The position limiting opening 461M is used for limiting the mounted component, such as but not limited to the lens 30. The under-wrap port 471M is used for accommodating the integrated base 11M, that is, when the array camera module 1000M is assembled, the driver 60 or the lens 30 is installed in the limiting port 461M of the filter element lens seat 40M, the integrated base 11M is accommodated in the under-wrap port 471M, the upward extending wall 46M limits and shields the lens 30, so that the optical axes of the lens 30 and the photosensitive element 20 are consistent, and the downward extending wall 47M shields the integrated base 11M, so that the array camera module 1000M has a regular overall structure, is convenient to install, and has an attractive appearance. The size of the limiting opening 461M and the size of the under-wrap opening 471M can be determined according to the size of the components to be mounted, for example, but not limited to, the size of the driver 60, the lens 30 and the integrated base 11M.

In one embodiment, the lower wall 47M may extend to the circuit board 12M, for example, but not limited to, by being fixedly connected to the circuit board 12M by gluing, so that the filter element base 40M is more stably mounted.

Each of the integrated bases 11N includes a lens wall 118N, and the lens wall 118N extends at least partially upward from the raised step 116N to form a lens chamber 1181N adapted to mount the lens 30, thereby forming a fixed focus camera module.

Further, the raised step 116N and the base main body 112N form the mounting groove 115N for mounting the filter element mount 40N. The lens wall 118N and the raised step 116N form another mounting slot 115N for providing a mounting location for the lens 30.

It is to be noted that each of the individual filter element mounts 40T may also be configured in any of the configurations described above in the first to tenth embodiments.

It should be noted that, in the above embodiment, a dual-lens array camera module formed by two camera module units 100 is taken as an example for description, and in other embodiments, the array camera module 1000 may further include more camera module units 100.

On the other hand, the filter element lens holder can be integrally formed, for example, by injection molding, so that the filter element lens holder has better flatness, and more preferably, the reflectivity of incident light can be reduced by using the characteristics of the material itself. Furthermore, it can be seen from the above embodiments that, in combination with the shape of the integral base, the filter element mount can have a variety of variations, is simple in molding structure and easy to process, and more preferably, when a suitable plastic material is selected, does not require etching or the like, and does not require blackening or roughening treatment, so that the reflectance of incident light can be reduced and stray light can be avoided.

The photosensitive element 321 includes a photosensitive region 3212 and a non-photosensitive region 3213, wherein the photosensitive region 3212 and the non-photosensitive region 3213 of the photosensitive element 321 are integrally formed, the photosensitive region 3212 is located in the middle of the photosensitive element 321, the non-photosensitive region 3213 is located outside the photosensitive element 321, and the non-photosensitive region 3213 surrounds the photosensitive region 3212. After the light reflected by the object enters the inside of the camera module through the optical lens 310, the light can be received by the photosensitive area 3212 of the photosensitive element 321 and photoelectrically converted to obtain an image associated with the object.

As can be understood by those skilled in the art, each of the die connectors 3211 of the light-sensing element 321 is disposed in the non-light-sensing region 3213 of the light-sensing element 321. In addition, the non-photosensitive region 3213 of the photosensitive element 321 has a chip inner side 32131, a chip connection portion 32132, and a chip outer side 32133, wherein the chip inner side 32131 surrounds the photosensitive region 3212, and two sides of the chip connection portion 32132 extend and are connected to the chip inner side 32131 and the chip outer side 32132, respectively. That is, a region of the non-photosensitive region 3213 from a position where the chip connector 3211 is disposed to a position of an edge of the photosensitive region 3212 is defined as the chip inner portion 32131, a region of the non-photosensitive region 3213 where the chip connector 3211 is disposed is defined as the chip connection portion 32132, and a region of the non-photosensitive region 3213 from a position where the chip connector 3211 is disposed to a position of an outer edge of the photosensitive element 321 is defined as the chip outer portion 32132. In other words, from the top view of the light sensing element 321, the light sensing element 321 includes the chip outer side portion 32133, the chip connection portion 32132, the chip inner side portion 32131, and the light sensing region 3212 in order from the outside to the inside.

In addition, the circuit board 322 includes a flat chip mounting region 3222 and an edge region 3223, wherein the edge region 3223 is integrally formed with the chip mounting region 3222, and the edge region 3223 is located around the chip mounting region 3222. The chip mounting region 3222 is used for mounting the photosensitive element 321, and the circuit board connecting member 3221 is disposed in the edge region 3223. The edge area 3223 of the circuit board 322 has a circuit board inner portion 32231, a circuit board connecting portion 32232 and a circuit board outer portion 32233, wherein the circuit board inner portion 32231 surrounds the chip mounting area 3222, and two sides of the circuit board connecting portion 32232 extend and are connected to the circuit board inner portion 32231 and the circuit board outer portion 32233, respectively. That is, a region of the edge region 3223 from the position where the wiring board connector 3221 is disposed to the position of the edge of the chip mounting region 3222 is defined as the wiring board inner side portion 32231, a region of the edge region 3223 where the wiring board connector 3221 is disposed is defined as the wiring board connecting portion 32232, and a region of the edge region 3223 from the position where the wiring board connector 3221 is disposed to the position of the outer edge of the edge region 3223 is defined as the wiring board outer side portion 32233. In other words, the wiring board 322 is, in order from the inside to the outside in a top view of the wiring board 322, the wiring board outer side portion 32233, the wiring board connecting portion 32232, the wiring board inner side portion 32231, and the chip mounting region 3222A. The type of the lead 324 is not limited in the camera module of the present invention, for example, in a specific example, the lead 324 may be implemented as a gold wire, that is, the light sensing element 321 and the circuit board 322 can be connected together by a gold wire, so that after the light sensing element 321 converts an optical signal into an electrical signal, the electrical signal can be further transmitted to the circuit board 322 through the lead 324. It will be understood by those skilled in the art that in other examples of the camera module, the leads 324 may be made of any material, such as silver wire, copper wire, etc., which can transmit the electrical signal between the photosensitive element 321 and the circuit board 322.

In addition, in one example, the camera module may be implemented as a fixed focus camera module, wherein the camera module allows the optical lens 310 to be held on the photosensitive path of the photosensitive element 321 by a lens holder assembled to the mold base 323.

In another example, the camera module may be implemented as a zoom camera module, wherein the camera module adjusts the focal length of the camera module by changing the distance between the optical lens 310 and the light sensing element 321. Specifically, in the example shown in fig. 62, the camera module further includes at least one driver 330, wherein each optical lens 310 is correspondingly disposed on each driver 330, each driver 330 is assembled on each mold base 323, and each driver 330 is electrically connected to each circuit board 322, so that after the circuit boards 322 transmit electric power and control signals to the drivers 330, the drivers 330 can drive the optical lenses 310 to move back and forth along the photosensitive paths of the photosensitive elements 321, thereby adjusting the focal length of the camera module. That is, the optical lens 310 is drivably provided to the driver 330.

It should be noted that the type of the driver 330 is not limited in the camera module of the present invention, for example, in a specific example, the driver 330 may be implemented as any driver, such as a voice coil motor, capable of driving the optical lens 310 to displace along the photosensitive path of the photosensitive element 321, wherein the driver 330 is capable of receiving power and a control signal to be in an operating state.

Further, referring to fig. 62, the image capturing module further includes at least one filter element 340, wherein each filter element 340 is assembled to each mold base 323, and each filter element 340 is located in a photosensitive path of each photosensitive element 321. The light reflected by the object enters the camera module from the optical lens 310, and is filtered by the filter 340, and then can be received by the light sensing element 321 and photoelectrically converted. That is, the filter element 340 can filter stray light, for example, infrared light, from light entering the camera module from the optical lens 310 and reflected by an object, and in this way, the imaging quality of the camera module can be changed.

It will be understood by those skilled in the art that, in different examples of the camera module, the filter element 340 can be implemented in different types, for example, the filter element 340 can be implemented as an ir-cut filter, a full-transmittance filter, and other filters or a combination of filters, for example, the filter element 340 can be implemented as a combination of an ir-cut filter and a full-transmittance filter, that is, the ir-cut filter and the full-transmittance filter can be switched to be selectively located on the photosensitive path of the photosensitive element 321, for example, when the camera module is used in an environment with sufficient light, such as daytime, the ir-cut filter can be switched to the photosensitive path of the photosensitive element 321 to filter the ir in the light reflected by the object entering the camera module by the ir-cut filter, when the camera module is used in a dark environment such as at night, the full-transmittance spectral filter can be switched to the photosensitive path of the photosensitive element 321 to allow the infrared part of the light reflected by the object entering the camera module to transmit.

Referring to fig. 62, the molded photosensitive component 320 of the camera module further includes a supporting element 325, wherein the supporting element 325 is disposed in the non-photosensitive region 3213 of the photosensitive element 321 before the molding base 323 is molded, so that after the molding base 323 is molded, the molding base 323 covers the circuit board 322, the non-photosensitive region 3213 of the photosensitive element 321 and a portion of the supporting element 325 to form the molded photosensitive component 320, wherein the supporting element 325 can effectively improve the yield of the camera module and improve the imaging quality of the camera module, and features and advantages of the supporting element 325 will be further described and disclosed in the following description.

Further, the support element 325 has a top surface 32501, an inner side surface 32502 and an outer side surface 32503, wherein two sides of the top surface 32501 are connected to the inner side surface 32502 and the outer side surface 32503, respectively. It is worth mentioning that the side of the supporting member 325 facing the photosensitive member 321 is defined as the inner side surface 32502 of the supporting member 325, and the side of the supporting member 325 facing the circuit board 322 is defined as the outer side surface 32503 of the supporting member 325.

Referring to fig. 62, the molded photo sensor module 320 of the camera module further includes a plurality of electronic components 326, wherein each of the electronic components 326 may be attached to the edge region 3223 of the circuit board 322 by a process such as smt (surface Mount technology). Preferably, each of the electronic components 326 is attached to the circuit board outer side portion 32233 of the edge region 3223. The light sensing element 321 and each of the electronic components 326 may be attached to the same side or opposite sides of the circuit board 322, for example, in a specific example, the light sensing element 321 and each of the electronic components 326 are attached to the same side of the circuit board 322, the light sensing element 321 is attached to the chip attachment region 3222 of the circuit board 322, and each of the electronic components 326 is attached to the edge region 3223 of the circuit board 322. After the mold base 323 is integrally formed on the circuit board 322, the mold base 323 covers each of the electronic components 326, so that the adjacent electronic components 326 are isolated from each other by the mold base 323, and the electronic components 326 and the photosensitive elements 321 are isolated from each other by the mold base 323, therefore, in the camera module of the present invention, even when the distance between the adjacent electronic components 326 is short, the mold base 323 can prevent the adjacent electronic components 326 from contacting or interfering with each other, and the way that the mold base 323 covers the electronic components 326 can prevent the photosensitive regions 3212 of the photosensitive elements 321 from being contaminated by contaminants generated on the surfaces of the electronic components 326, thereby reducing the volume of the camera module and improving the imaging quality of the camera module. That is, in the camera module of the present invention, the electronic component 326 is covered by the mold base 323, so that more electronic components 326 can be mounted on the circuit board 322 with a small area. It is worth mentioning that the types of the electronic components 326 include, but are not limited to, resistors, capacitors, driving devices, and the like.

In addition, it can be understood by those skilled in the art that although the manufacturing steps of the camera module and the manufacturing steps of the molded photosensitive element 320 are disclosed in fig. 56 to 62 by taking a single camera module as an example, in this example shown in fig. 8, the camera module can also be implemented as a dual-lens camera module or an array camera module, and the invention is not limited in this respect.

The manufacturing steps of the camera module and the molding photosensitive member 320 are described in the examples shown in fig. 56 to 62.

Referring to fig. 56, the photosensitive element 321 is attached to the chip attachment region 3222 of the circuit board 322, and each of the chip connectors 3211 of the non-photosensitive region 3213 of the photosensitive element 321 and each of the circuit board connectors 3221 of the edge region 3223 of the circuit board 322 are connected by a set of the leads 324. In addition, each of the electronic components 326 is attached to the circuit board outer side portion 32233 of the edge area 3223 of the circuit board 322. That is, two ends of a group of the leads 324 are respectively connected to the photosensitive element 321 and the circuit board 322, wherein each of the leads 324 protrudes out of the upper surface of the photosensitive element 321 in an upward arc shape. It is understood that, limited by the wire bonding process using the wire 324 to connect the photosensitive element 321 and the circuit board 322 and the characteristics of the wire 324 itself, the two ends of the wire 324 need to protrude upward in an arc shape from the upper surface of the photosensitive element 321 after each of the chip connectors 3211 connected to the non-photosensitive region 3213 of the photosensitive element 321 and each of the circuit board connectors 3221 connected to the outer region 223 of the circuit board 322. In addition, the curvature of each lead 324 is kept smooth, which is beneficial to ensure the ability of the lead 324 to transmit the electrical signal between the photosensitive element 321 and the circuit board 322. Wherein each of the leads 324 is arranged between the photosensitive element 321 and the circuit board 322, for example, each of the leads 324 may be equally spaced. It will be understood by those skilled in the art that maintaining each of the leads 324 in an initial state during the manufacturing process of the camera module and during the use of the camera module is advantageous for ensuring the ability of the leads 324 to transmit the electrical signals between the photosensitive element 321 and the circuit board 322, thereby ensuring the imaging quality of the camera module.

It can be understood by those skilled in the art that although the manufacturing steps of the camera module and the manufacturing steps of the molded photosensitive assembly 320 of the camera module are illustrated in fig. 56 by taking an example in which one photosensitive element 321 is attached to one circuit board 322, in another example, a plurality of photosensitive elements 321 may be attached to different positions of one circuit board 322 to subsequently manufacture a dual-lens camera module or an array camera module, in another example, a plurality of circuit boards 322 may be attached together to form a circuit board assembly, and then each photosensitive element 321 is attached to the corresponding position of the circuit board assembly to subsequently separate the circuit board assembly. The invention is not limited in this respect.

Referring to fig. 57A and 57B, the supporting element 325 is disposed in the non-photosensitive region 3213 of the photosensitive element 321 to form a semi-finished molded photosensitive assembly from the photosensitive element 321, the circuit board 322 and the supporting element 325, wherein the supporting element 325 is disposed to cover the chip inner portion 32131, the chip connecting portion 32132 and the chip outer portion 32133 of the non-photosensitive region 3213 of the photosensitive element 321. That is to say. The supporting element 325 can cover a portion of each lead 324, so that the supporting element 325 can cover the leads 324 in the subsequent process of manufacturing the camera module and the process of molding the photosensitive assembly 320, so as to improve the imaging quality of the camera module. As will be understood by those skilled in the art, in this embodiment of the camera module of the present invention, the supporting element 325 covers the chip connector 3211 of the photosensitive element 321. Further, the supporting member 325 includes a frame-shaped supporting body 3251 and a through hole 3252, wherein the supporting body 3251 is disposed on the non-photosensitive region 3213 of the photosensitive member 321, so that the photosensitive region 3212 of the photosensitive member 321 corresponds to the through hole 3252 of the supporting member 325, and thus the supporting body 3251 can protect the photosensitive region 3212 of the photosensitive member 321 when the molding process is performed. The molded base 323, after molding, encapsulates the outer side surface 32503 and at least a portion of the top surface 32501 of the support body 3251. It is worth mentioning that the inner side surface 32502 of the support element 325 is adapted to form the through hole 3252 of the support element 325.

Preferably, the supporting body 3251 covers the chip inner portion 32131, the chip connecting portion 2131 and the chip outer portion 32133 of the photosensitive element 321, that is, the supporting body 3251 can cover the chip connecting member 3211, so that the supporting body 3251 can prevent the connecting position of the lead 324 and the chip connecting member 3211 from contacting with the molding material for forming the molding base 323 to prevent the lead 324 from falling off from the chip connecting member 3211. It is understood that when the supporting body 3251 covers the connecting positions of the leads 324 and the chip connector 3211, the supporting body 3251 can isolate the connecting positions of the leads 324 and the chip connector 3211 from the molding material, so as to prevent the molding material from causing deformation of the end portions of the leads 324 for connecting the chip connector 3211 or separation of the leads 324 from the chip connector 3211 during the molding process. In one embodiment, the support body 3251 can be formed by disposing glue on the non-photosensitive region 3213 of the photosensitive element 321 and curing the glue to make the support body 3251 elastic, wherein the inner side surface 32502 of the support body 3251 forms the through hole 3252 after the support body 3251 is formed, and the photosensitive region 3212 of the photosensitive element 321 corresponds to the through hole 3252. In addition, the supporting body 3251 formed by glue may also have viscosity for adhering contaminants such as dust, etc. subsequently, so as to prevent the contaminants from contaminating the photosensitive region 3212 of the photosensitive element 321 and causing a dirty spot on the photosensitive region 3212 of the photosensitive element 321, thereby further ensuring the imaging quality of the camera module. For example, the support body 3251 is disposed between the photosensitive region 3212 of the photosensitive element 321 and the electronic component 326, so that contaminants such as solder powder generated when the electronic component 326 is mounted on the circuit board 322 are adhered to the support body 3251, thereby preventing the contaminants such as solder powder from contaminating the photosensitive region 3212 of the photosensitive element 321.

Preferably, the support body 3251 may be formed by applying glue in a glue state to the non-photosensitive region 3213 of the photosensitive element 321 and curing the glue, so as to prevent the glue from flowing after being applied to the non-photosensitive region 3213 of the photosensitive element 321 and contaminating the photosensitive region 3212 of the photosensitive element 321. In other words, the glue has good plasticity before curing to form the support body 3251, so as to avoid the glue from being coated on the non-photosensitive region 3213 of the photosensitive element 321 and deforming during curing. It can be understood by those skilled in the art that the supporting body 3251 formed by glue can cover the lead 324 by applying the glue in a glue state to the non-photosensitive region 3213 of the photosensitive element 321, and damage to the lead 324 can be avoided during the process of applying the glue to the non-photosensitive region 3213 of the photosensitive element 321.

Referring to fig. 58, when the molding process is performed, the molding material is solidified by a molding die 3100 to form the molding base 323 integrally molded with at least the circuit board 322, so that the size of the camera module and the assembly error of the camera module can be reduced, thereby making the structure of the camera module more compact and improving the imaging quality of the camera module.

Specifically, the molding die 3100 includes an upper die 3101 and a lower die 3102, wherein at least one of the upper die 3101 and the lower die 3102 can be moved to enable the upper die 3101 and the lower die 3102 to be subjected to a mold closing operation, and at least one molding space 3103 is formed between the upper die 3101 and the lower die 3102, wherein the molding base 323 is formed by the molding material added to the molding space 3103 and after being cured. For example, in one embodiment, the lower die 3102 is generally fixed and the upper die 3101 is capable of movement relative to the lower die 3102 along guide posts to clamp when the upper die 3101 is moved toward the lower die 3102, thereby forming the forming space 3103 between the upper die 3101 and the lower die 3102, and to draw when the upper die 3101 is moved away from the lower die 3102. Or in another example, the upper die 3101 is fixed and the lower die 3102 is movable relative to the upper die 3101 along guide posts to clamp when the lower die 3102 is moved toward the upper die 3101, thereby forming the molding space 3103 between the lower die 3102 and the upper die 3101, and to draw when the lower die 3102 is moved away from the upper die 3101.

Forming the molded semi-finished photosensitive assembly after the photosensitive element 321 and the wiring board 322 are connected by a set of the leads 324 and the support body 3251 is formed at the non-photosensitive region 3213 of the photosensitive element 321 to cover a portion of the leads 324, placing the molded semi-finished photosensitive assembly on the lower mold 3102 of the molding mold 3100, operating the upper mold 3101 and/or the lower mold 3102 of the molding mold 3100 to close the upper mold 3101 and the lower mold 3102 to form the molding space 3103 between the upper mold 3101 and the lower mold 3102, and the photosensitive element 321, the wiring board 322, and the support element 325 are respectively partially the molding space 3103 of the molding mold 3100, wherein a press-fit surface 31011 of the upper mold 3101 is in contact with the top surface 32501 of the support body 3251 to support the upper mold 3101 upwardly by the support body 3251, so as to prevent the press-fit surface 31011 of the upper mold 3101 from pressing the lead 324. For example, in this particular example of the present invention, such as that shown in fig. 62, the exterior of the circuit board 322, the non-photosensitive region of the photosensitive element 321, and a portion of the support element 325 are located in the forming space 3103 of the forming mold 3100, such that the molding base 323 covers the exterior of the circuit board 322, the non-photosensitive region of the photosensitive element 321, and a portion of the support element 325 after the molding base 323 is formed in the forming space 3103.

Accordingly, it will be understood by those skilled in the art that the forming space 3103 of the forming mold 3100 may be an annular space to form the annular molding base 323 after the molding material is introduced into the forming space 3103 and cured.

It is worth mentioning that the support body 3251 has elasticity, so that when the molding die 3100 is subjected to a die closing operation, an impact force generated at a moment when the press-fit surface 31011 of the upper die 3101 of the molding die 3100 contacts the top surface 32501 of the support body 3251 is absorbed by the support body 3251 to prevent the impact force from being further transmitted to the photosensitive element 321, thereby preventing the photosensitive element 321 from being damaged or preventing the photosensitive element 321 from being displaced relative to the photosensitive element 321 due to the force. As will be understood by those skilled in the art, the supporting body 3251 can absorb the impact force to prevent the impact force from being further transmitted to the photosensitive element 321, so as to ensure that the flatness of the photosensitive element 321 when the photosensitive element 321 is attached to the circuit board 322 is not affected, thereby ensuring the imaging quality of the camera module.

It is worth mentioning that the shore hardness of the support main body 3251 ranges from a50 to a80, and the elastic modulus ranges from 0.1Gpa to 1 Gpa.

Preferably, in this example of the invention such as that shown in fig. 62, the height of the support body 3251 may be implemented to be higher than or equal to the height at which the lead 324 protrudes upward, so that the support body 3251 can support the upper mold 3101 upward while preventing the upper mold 3101 from pressing the lead 324 when the press-fit surface 31011 of the upper mold 3101 of the molding mold 3100 is in contact with the top surface 32501 of the support body 3251 when the molding mold 3100 is subjected to a mold clamping operation. For example, in one example, the support body 3251 has a height equal to a height of the lead 324 protruding upward, so that when the upper mold 3101 and the lower mold 3102 of the molding die 3100 are clamped, the support body 3251 supports the upper mold 3101 upward so that the press-fit surface 31011 of the upper mold 3101 can contact the lead 324 but the press-fit surface 31011 of the upper mold 3101 cannot press the lead 324. In another example, the support body 3251 has a height higher than a height at which the lead 324 protrudes upward, so that when the upper mold 3101 and the lower mold 3102 of the molding mold 3100 are clamped, the support body 3251 supports the upper mold 3101 upward so that the press-fit surface 31011 of the upper mold 3101 does not contact the lead 324, thereby preventing the press-fit surface 31011 of the upper mold 3101 from pressing the lead 324. That is, the support body 3251 can support the upper mold 3101 upward to reserve a safety distance between the press-fit surface 31011 of the upper mold 3101 and the lead 324.

In addition, the support body 3251 has elasticity, and after the upper mold 3101 and the lower mold 3102 of the molding mold 3100 are subjected to a mold closing operation, the press-fit surface 31011 of the upper mold 3101 is brought into contact with the top surface 32501 of the support body 3251 to press the top surface 32501 of the support body 3251, wherein the pressure applied to the top surface 32501 of the support body 3251 by the press-fit surface 31011 of the upper mold 3101 can cause the support body 3251 to be slightly deformed so as to prevent a gap from being generated between the press-fit surface 31011 of the upper mold 3101 and the top surface 32501 of the support body 3251. That is, the upper mold 3101 of the molding module 100 can be closely attached to the support body 3251 so that the photosensitive region of the photosensitive element 321 corresponding to the through hole 3252 of the support element 325 is in a sealed environment to prevent the molding material from entering the sealed environment and contaminating the photosensitive region of the photosensitive element 321 during the molding process.

In a modified embodiment of the molded photosensitive assembly 320 of the present invention, in a process, the supporting element 325 may be made of a hard material, that is, when the supporting body 3251 of the supporting element 325 is formed on at least a portion of the non-photosensitive region 3213 of the photosensitive element 321, and the pressing surface 31011 of the upper mold 3101 of the forming mold 3100 presses the top surface 32501 of the supporting body 3251, the supporting body 3251 is not deformed, so as to ensure good electrical performance of the leads 324, thereby ensuring yield of the camera module in subsequent processes and further ensuring imaging quality of the camera module.

It is worth mentioning that the shore hardness of the support body 3251 is greater than D70, and the elastic modulus is greater than 1 Fpa.

The molding die 3100 further includes a cover film 3106, so that when the upper die 3101 and the lower die 3102 are clamped, the cover film 3106 is positioned between the press-fit surface 31011 of the upper die 3101 and the top surface 32501 of the support body 3251, and preferably, the cover film 3106 may be first provided on the press-fit surface 31011 of the upper die 3101 between the upper die 3101 and the lower die 3102 being clamped. By providing the cover film 3106 between the press-fit surface 31011 of the upper mold 3101 and the support body 3251, it is possible to prevent a gap from being generated between the press-fit surface 31011 of the upper mold 3101 and the support body 3251, and to absorb an impact force generated when the upper mold 3101 and the lower mold 3102 are clamped, thereby preventing the photosensitive element 321, the wiring board 322, and the lead wire 324 from being damaged when the upper mold 3101 and the lower mold 3102 are clamped.

Referring to fig. 59, after the molding material in a fluid state is added to the molding space 3103 of the molding die 3100, the molding material fills the entire molding space 3103, wherein the support body 3251 formed in the non-photosensitive region 3213 of the photosensitive element 321 is capable of preventing the molding material from entering the photosensitive region 3212 of the photosensitive element 321 at a contact position of the support body 3251 and the non-photosensitive region 3213 of the photosensitive element 321, in addition, the support body 3251 is deformed to prevent a gap from being generated between the press-fit surface 31011 of the upper mold 3101 and the top surface 32501 of the support body 3251, so that the molding material can be prevented from entering the sealed environment at a contact position between the top surface 32501 of the support body 3251 and the press-fit surface 31011 of the upper mold 3101, and the occurrence of "flash" after the molding material is cured can be prevented.

It is worth mentioning that the fluid-like forming material according to the present invention may be a liquid material or a solid particulate material or a mixture of liquid and solid particulate material, it being understood that whether the forming material is embodied as a liquid material or as a solid particulate material or as a mixture of liquid and solid particulate material, it is capable of solidifying to form the molding base 323 after being introduced into the forming space 3103 of the forming mold 3100. For example, in this specific example of the invention, the molding material in fluid form is embodied as a thermoplastic material, such as a liquid, wherein the molding material solidifies after being introduced into the molding space 3103 of the molding die 3100 to form the molding base 323. It should be noted that the way of solidifying the fluid molding material after the fluid molding material is added into the molding space 3103 of the molding die 3100 is not intended to limit the scope and content of the present invention.

Referring to fig. 60, the supporting body 3251 is disposed along the non-photosensitive region 3213 of the photosensitive element 321, after the molding material is added into the forming space 3103 of the forming mold 3100, the supporting body 3251 can prevent the molding material from entering the photosensitive region 3212 of the photosensitive element 321, so that after the molding material is solidified to form the molding base 323, the molding base 323 further forms a light window 3231 to correspond to the photosensitive region 3212 of the photosensitive element 321, so that subsequently, the light window 3231 of the molding base 323 allows light to pass through to be received by the photosensitive region 3212 of the photosensitive element 321 and perform photoelectric conversion. That is, the molding material added to the molding space 3103 of the molding die 3100 forms a molded body 3232 of the molding base 323 and the light window 3231 in the middle of the molding base 323 after being cured. In other words, the mold base 323 includes the mold body 3232 and the light window 3231, the light window 3231 provides a light path for the optical lens 310 and the light sensing element 321, so that after the light reflected by the object enters the inside of the camera module from the optical lens 310, the light is received and photoelectrically converted by the light sensing region 3212 of the light sensing element 321 through the light window 3231 of the mold base 323.

It should be noted that after the mold base 323 is formed, the mold base 323 covers each electronic component 326, so as to isolate each electronic component 326 by the mold base 323 and isolate the electronic component 326 and the photosensitive element 321 by the mold base 323, in this way, even if the adjacent electronic components 326 are close to each other, the mold base 323 can prevent the adjacent electronic components 326 from contacting each other, and the mold base 323 can prevent the contaminants generated by the electronic components 326 from contaminating the photosensitive area of the photosensitive element 321, so as to improve the imaging quality of the camera module.

Referring to fig. 61, the filter element 340 is assembled on the top surface of the mold base 323, so that the filter element 340 closes the optical window 3231 of the mold base 323, so that the subsequent light entering the interior of the camera module from the optical lens can be further filtered by the filter element 340 to improve the imaging quality of the camera module.

Further, the top surface of the mold base 323 forms an inner side surface 3233 and an outer side surface 3234, wherein in one example, the inner side surface 3233 and the outer side surface 3234 of the mold base 323 are in the same plane, so that the top surface of the mold base 323 forms a flat plane, wherein the filter element 340 is assembled to the inner side surface 3233 of the mold base 323, the driver 330 or the lens mount is assembled to the outer side surface 3234 of the mold base 323, or the optical lens 310 is directly assembled to the outer side surface 3234 of the mold base 323. In another example, the plane of the inner side surface 3233 of the mold base 323 may be lower than the plane of the outer side surface 3234, so that the top surface of the mold base 323 forms a step-like surface, that is, the plane of the inner side surface 3233 of the mold base 323 is lower than the plane of the outer side surface 3234 to form a groove 3235 of the mold base 323, wherein the filter element 340 assembled to the inner side surface 3233 of the mold base 323 is accommodated in the groove 3235 of the mold base 323, and the driver 330 is assembled to the outer side surface 3234 of the mold base 323, so that the optical lens 310 assembled to the driver 330 is further maintained in the photosensitive path of the photosensitive element 321, as shown in fig. 62, thereby obtaining the camera module.

Referring to fig. 64A, a first modified embodiment of the camera module of the present invention is shown, and unlike the above-described embodiment of the camera module of the present invention, each of the leads 324 of the molded photosensitive member 320 of the camera module of the present invention is entirely covered inside the support body 3251.

Specifically, the support body 3251 covers at least a part of the chip inner portion 32131, the chip connecting portion 32132, the chip outer portion 32133, the wiring board inner portion 32231, the wiring board connecting portion 32232, and at least a part of the wiring board outer portion 32233, so that the support body 3251 covers not only the catch of the lead 324 but also the connecting position of the lead 324 and the chip connecting member 3211 of the photosensitive element 321 and the connecting position of the wiring board connecting member 3221 covering the lead 324 and the wiring board 322 to pre-fix the lead 324 by the support body 3251. Thus, when the molding base 323 is formed by a subsequent molding process, the press-fit surface 31011 of the upper mold 3101 is in contact with the top surface 32501 of the support body 3251 during the process of closing the upper mold 3101 and the lower mold 3102 of the molding mold 3100, so that the press-fit surface 31011 of the upper mold 3101 is prevented from directly pressing the lead 324, thereby preventing the lead 324 from being deformed or damaged by a force.

In addition, the lead wires 324 are entirely covered inside the support body 3251, so that the support body 3251 can prevent the molding material added to the molding space 3103 formed between the upper mold 3101 and the lower mold 3102 from directly contacting the lead wires 324, thereby preventing the molding material having a high temperature from damaging the lead wires 324. Preferably, the support body 3251 has good thermal insulation properties to prevent the support body 3251 from transferring the temperature of the molding material to the lead 324. More preferably, the support body 3251 has a height higher than that of the protruding portion of the lead 324, so that the support body 3251 supports the upper mold 3101 upward to reserve a safety distance between the press-fit surface 31011 of the upper mold 3101 and the protruding portion of the lead 324 when the molding process is performed.

In addition, the supporting body 3251 covers the chip outer side portion 32133 of the photosensitive element 321 and the circuit board inner side portion 32231 of the circuit board 322, so that the supporting body 3251 covers the mounting positions of the photosensitive element 321 and the circuit board 322, and in this way, the supporting body 3251 can not only pre-fix the photosensitive element 321 and the circuit board 322, so that the supporting body 3251 can prevent the photosensitive element 321 and the circuit board 322 from being displaced due to uneven stress when a molding process is performed, but also prevent the molding material from contacting the positions of the photosensitive element 321 and the circuit board 322, so as to ensure the flatness of the photosensitive element 321 and improve the mounting quality of the camera module.

It will be understood by those skilled in the art that the supporting body 3251 is disposed along the mounting position of the light-sensing element 321 and the circuit board 322, so that the supporting body 3251 is in a square frame shape, so that the supporting body 3251 can prevent the molding material from entering the light-sensing region 3212 of the light-sensing element 321 when the molding process is performed, so that the molding material forms the molding body 3232 covering the edge region 3223 of the circuit board 322 and the outer side surface 32503 of the supporting body 3251 after being cured, and forms the light window 3231 in the middle of the molding body 3232, wherein the light-sensing region 3212 of the light-sensing element 321 corresponds to the light window 3231 of the molding base 323, so that the light window 3231 provides a light path for the optical lens 310 and the light-sensing element 321. Preferably, the molded body 3232, after molding, encases at least a portion of the edge region 3223 of the circuit board 322, the outer side surface 32503 of the support body 3251, and the top surface 32501.

In a second modified embodiment of the imaging module according to the present invention shown in fig. 64B, the support main body 3251 covers at least a part of the chip outer portion 32133 of the photosensitive element 321, the wiring board inner portion 32231 of the wiring board 322, the wiring board connecting portion 32232, and the wiring board outer portion 32233. That is, in this example of the image pickup module shown in fig. 64B, the support body 3251 may not cover the chip connecting portion 32132 of the photosensitive element 321. In the third embodiment of the imaging module according to the present invention shown in fig. 64C, the support main body 3251 covers the chip connecting portion 32132 and the chip outer portion 32133 of the photosensitive element 321 and the wiring board inner portion 32231 and the wiring board connecting portion 32232 of the wiring board 322. That is, in the embodiment of the image pickup module of the present invention shown in fig. 64C, the support main body 3251 may not cover the chip inner portion 32131 of the photosensitive element 321 and the wiring board outer portion 32233 of the wiring board 322. That is, in the several modified embodiments of the camera module shown in fig. 64A, 64B and 64C, the support body 3251 can cover the mounting positions of the photosensitive element 321 and the circuit board 322 at the same time, so as to pre-fix the photosensitive element 321 and the circuit board 322 by the support body 3251, and prevent gaps from being generated at the mounting positions of the photosensitive element 321 and the circuit board 322 by the support body 3251, so that the support body 3251 can prevent the photosensitive element 321 and the circuit board 322 from being displaced due to uneven stress at each part during the molding process, and the support body 3251 can prevent the molding material from entering between the photosensitive element 321 and the circuit board 322 to ensure the flatness of the photosensitive element 321.

Referring to fig. 65A, a fourth modified embodiment of the camera module according to the present invention is shown, in which the supporting body 3251 covers at least a portion of the inner portion 32231, the connecting portion 32232 and at least a portion of the outer portion 32233 of the circuit board of the edge region 22 of the circuit board 322, that is, the supporting body 3251 covers the circuit board connector 3221 of the circuit board 322, so that during the molding process, on one hand, the lead 324 is pre-fixed by the supporting body 3251, and on the other hand, the lead 324 and the circuit board connector 3221 are prevented from contacting with the molding material by the supporting body 3251, thereby preventing the lead 324 from falling off the circuit board connector 3221.

Fig. 65B shows a fifth modified embodiment of the camera module according to the present invention, in which the support body 3251 covers only the chip inner side portion 32131 of the photosensitive element 321, so that when the molding process is performed, the support body 3251 prevents the molding material from entering the photosensitive region 3212 of the photosensitive element 321, thereby forming the molding body 3232 covering the edge region 3223 of the circuit board 322 and the chip outer side portion 32133 of the photosensitive element 321 and the chip connecting portion 32132 after the molding material is cured, and forming the optical window 3231 at a position corresponding to the photosensitive region 3212 of the photosensitive element 321.

Referring to fig. 66, a sixth variant embodiment of the camera module of the invention is shown, differing from the previous embodiment of the invention in that the molded body 3232 is not formed to cover the top surface 32501 of the support body 3251. In this particular example, as shown for example in fig. 66, the molded body 3232, after molding, encases the edge region 3223 of the wiring board 322 and the outer side surface 32503 of the support body 3251.

It should be noted that although fig. 56 to 66 all show that the height of the support body 3251 is higher than the height of the protruding portion of each lead 324, in other examples of the camera module of the present invention, the height of the support body 3251 may be equal to the height of the protruding portion of each lead 324, or in other examples, the height of the support body 3251 may be lower than the height of the protruding portion of each lead 324, as long as the pressing surface 31011 of the upper mold 3101 of the forming mold 3100 is in contact with the top surface of the support body 3251 and the pressing surface of the upper mold 3101 does not directly press each lead 324 when the molding process is performed.

Fig. 67 shows a variant embodiment of the camera module, in which the filter element 340 is not directly assembled to the molded body 3232, but at least one support 370 is provided by the camera module, i.e. the molded photosensitive assembly further comprises at least one support 370, the filter element 340 is assembled to the support 370, and then the support 370 is assembled to the top surface 3236 of the molded body 3232, so that the filter element 340 is held between the optical lens 310 and the photosensitive element 321, in such a way that it is directly attached to the molded body 3232 with respect to the filter element, and a buffer is provided by the support 370 so that the filter element 340 is not easily damaged and chipped, and the size of the filter element 340 can be reduced, and the height of the camera module can be reduced. Further, the top surface 3236 of the molded body 3232 may be a flat surface, so that after the molded base 323 is formed, the support 370 is assembled to the top surface 3236 of the molded body 3232, and then a lens carrier, such as the driver 330 or the lens barrel, is assembled to the support 370, or the lens 10 is directly assembled to the support 370. That is, the driver 330, or the lens barrel, or the lens 10 may not be directly assembled to the top surface 3236 of the molded body 3232, but may be assembled to the holder 370.

The holder 370 has a ring structure with a through hole formed in the middle, and includes a holder body 371 having a ring structure and an inwardly extending arm 372, the inwardly extending arm 372 integrally extending inwardly from the inner surface of the holder body 371 to form a supporting groove 373 at the top side of the inwardly extending arm 372 for mounting the filter element 340. That is, the holder 370 corresponds to the filter element holder 40 mentioned in the above-mentioned embodiment, the holder body 371 corresponds to the filter element holder body 43, and the inwardly extending arm 372 corresponds to the inwardly extending arm 44 mentioned in the above-mentioned embodiment.

In the present invention, the support 370 is a filter element holder, which may be implemented as the structure of the filter element holder in the embodiment illustrated in fig. 2 to 23, the mold base 323 may be implemented as the structure of the integrated base in the embodiment illustrated in fig. 2 to 23, and the structure of the support 370 and the mold base 323 cooperating with each other may also be implemented as the structure of the filter element holder and the integrated base illustrated in fig. 2 to 23 cooperating with each other.

In the present invention, the molding base 323 of the camera module is integrally packaged in the circuit board 322 and at least a part of the non-photosensitive area 3213 of the photosensitive element 321, so that the molding base 323 has a top surface with a larger area than that of the circuit board 322, so as to provide a mounting surface with a larger size for the support 370.

More specifically, the photosensitive element 321 has a photosensitive element connector 3211, the circuit board 322 has a circuit board connector 3221, the photosensitive element connector 3211 and the circuit board connector 3221 are connected by a set of connecting wires 324 so that the photosensitive element 321 is operatively connected to the circuit board 322, and the molding base 323 and the supporting element 325 further embed the photosensitive element connector 3211, the circuit board connector 3221 and the connecting wires 324. The mold base 323 integrally encapsulates the wiring board 322 and the photosensitive element 321 and integrally embeds the connecting wire 324, thereby preventing stray light from being reflected to the photosensitive element 321 due to the exposed connecting wire 324.

The holder 370 is supported on the top surface 3236 of the mold base 323, and the holder 370 forms an optical window with the mold base 323 to provide a light path for the photosensitive element 321, wherein an inner edge 3237 of the top surface 3236 of the mold base 323 is closer to the optical axis X of the camera module than an outer edge 32211 of the circuit board connector 3221, that is, the inner edge 3237 of the top surface 3236 of the mold base 323 is closer to the optical axis X of the camera module, so as to increase the area of the top surface 3236 of the mold base 323 for supporting the holder 370 serving as a filter element mount. As shown in the drawing, in the sectional view, the distance between the inner edge 3237 of the top surface 3236 of the mold base 323 and the optical axis X is shown as D1, and the distance between the outer edge 32211 of the wiring board connector 3221 and the optical axis X is shown as D2, where D1 is not greater than D2, so that the inner edge 3237 of the top surface 3236 of the mold base 323 is located further inside the camera module, thereby increasing the area of the top surface 3236 of the mold base 323.

It is understood that, as shown in fig. 67, a top surface area S of the mold base 323 corresponding to between the outer edge 32211 of the wiring board connector 3221 and the inner edge 3237 of the top surface 3236 of the mold base 323 is equivalent to an area where the mold base 323 is integrally encapsulated only at the edge of the wiring board 322 and not at least the photosensitive element 321 and the connecting wire 324 can be increased, so that the support 370 can be more stably supported, and a flatter enlarged mounting surface is provided for the support 370, and assembly tolerance is reduced.

In addition, it is understood that, in order to facilitate the demolding operation of the molding process and avoid stray light, the inner surface of the molding base 323 generally extends obliquely to form an optical window with an opening gradually increasing from bottom to top, which may cause the area of the top surface of the molding base 323 to tend to decrease and not to provide a sufficient mounting area, compared to the integrated base that is only integrally packaged at the edge of the circuit board in fig. 2 to 23, the integrated packaging of this embodiment of the present invention at the circuit board 322 and the photosensitive element 321 and embedding the circuit board connecting part 3221 and the connecting wire 324, the molding base 323 can make full use of the position space above the photosensitive element connecting part 3211, the circuit board connecting part 3221 and the connecting wire 324, so that the part extending obliquely corresponding to the inner surface of the molding base 323 is mainly concentrated at the parts 3211, and the connecting wire 324, The connecting wires 324 and the circuit board connecting piece 3221 are arranged above, so that the end of the inner surface of the molding base 323 extending obliquely away from the photosensitive element 321, namely the inner edge 3237 of the top surface 3236 of the molding base 323, does not exceed the outer edge of the circuit board connecting piece 3221, and thus a larger area of the top surface 3236 can be obtained for the top side of the molding base 323, and a larger area of a mounting surface can be provided.

In addition, compared to the conventional camera module illustrated in fig. 1B, the mirror base 7 is adhered to the circuit board 2 through the supporting leg 701, and the bottom surface of the supporting member 370, which is collocated with the filter element 340, provides a larger adhering area with the mold base 323, as shown in fig. 12, the adhering area of the supporting member 370 in contact with the mold base 323 is the top surface 3236 of the mold base 323, so that the supporting member 370 can be more firmly combined with the mold base 323, and the adhering area is increased, thereby more effectively avoiding the inclination of the supporting member 370, which causes the influence on the imaging quality.

In addition, the combination of the mold base 323 and the support 370 can replace the conventional lens holder 7 in fig. 1B, the mold base 323 has a larger connection strength because it is integrally combined with the circuit board 322, and the support 370 is a structural member for carrying the filter element 340. The two-part combination can thus provide greater support for the upper lens 310, or lens assembly with actuator 330 or barrel, relative to the lens mount 7 illustrated in fig. 1B. That is, the stress applied to the support member 370 can be more effectively transmitted to the mold base 323 and the wiring board 322. Also, since the mold base 323 and the wiring board 322 are integrally encapsulated, the bonding is more secure and the stress can be more effectively dispersed.

Moreover, the combination of the support 370 and the molded base 323 replaces the conventional mirror base 7 of FIG. 1B, so that the thickness of the support 370 is significantly reduced relative to the conventional mirror base 7 to which the filter element is mounted, and the thickness of the support 370 is below 0.7mm in the present invention.

Fig. 68 shows another modified embodiment of the camera module, in which the top surface 3236 of the molded body 3232 has two stepped surfaces 32361 and 32362, the groove 3235 is formed on the top side of the first stepped surface 32361, and the holder 370 assembled to the first stepped surface 32361 of the top surface 3236 of the molded body 3232 is received in the groove 3235 to further reduce the height dimension of the camera module. The holder 370 has a ring structure with a through hole formed in the middle, and includes a holder body 371 having a ring structure and an inwardly extending arm 372, the inwardly extending arm 372 integrally extending inwardly from the inner surface of the holder body 371 to form a supporting groove 373 at the top side of the inwardly extending arm 372 for mounting the filter element 340. At this time, the driver 330, or the lens barrel, or the lens 10 may be directly assembled to the second stepped surface 32362 of the top surface 3236 of the molded body 3232. It is understood that in other modified embodiments, the driver 330, or the lens barrel, or the lens 10 may also be assembled to the molded body 3232 and the holder 370.

However, it can be understood by those skilled in the art that in other examples of the camera module of the present invention, the optical lens 310 can also be directly assembled on the top surface of the molded body 3232 or the optical lens 310 can also be directly assembled on the top surface of the support 370.

The mold base 323 of the camera module is integrally encapsulated in the circuit board 322 and at least a portion of the non-photosensitive area 3213 of the photosensitive element 321, such that the mold base 323 has a top surface 3236 with a larger area than that of the circuit board 322 to provide a larger size mounting surface for the support 370. For example, in the embodiment shown in the figure, the support member 370 provides a mounting surface, which is partially the second stepped surface 32362 for supporting the actuator 330 of the lens assembly, and partially the first stepped surface 32361 for supporting the support member 370.

More specifically, the photosensitive element 321 has a set of photosensitive element connectors 3211, the circuit board 322 has a set of circuit board connectors 3221, the photosensitive element connectors 3211 and the circuit board connectors 3221 are connected by a set of connecting wires 324 so that the photosensitive element 321 is operatively connected to the circuit board 322, and the molding base 323 and the supporting element 325 further embed the photosensitive element connectors 3211, the circuit board connectors 322 and the connecting wires 324; wherein the holder 370 is supported on the top surface 3236 of the mold base 323, and the holder 370 forms an optical window in cooperation with the mold base 323 to provide a light path for the photosensitive element 321, wherein an inner edge 3237 of the top surface 3236 of the mold base 323 is closer to the optical axis X of the camera module than an outer edge 32211 of the circuit board connector 3221 to increase the area of the top surface 3236 of the mold base 323, and particularly, a first step surface 32361 is provided for supporting the holder 370 as a filter element mount. As shown in the drawings, in a cross-sectional view, the inner edge 3237 of the top surface 3236 of the mold base 323 is an inner edge of the first step surface 32361, a distance from the optical axis X is shown as D1, and a distance from the outer edge 32211 of the board connector 3221 to the optical axis X is shown as D2, where D1 is not greater than D2, so that the inner edge 3237 of the top surface 3236 of the mold base 323 is located further inside the camera module, thereby increasing an area of the top surface 3236 of the mold base 323.

As shown in fig. 68, a top surface area S of the mold base 323 corresponding to a space between the outer edge 32211 of the wiring board connector 3221 and the inner edge 3237 of the top surface 3236 of the mold base 323 is at least an area that can be increased corresponding to an area where the mold base 323 is integrally encapsulated only in the edge of the wiring board 322, so that the support member 370 can be more stably supported, and a flatter enlarged mounting surface is provided for the support member 370, and assembly tolerance is reduced.

The end of the inner surface of the mold base 323 extending obliquely away from the photosensitive element 321, that is, the inner edge of the first step face 32361 of the top surface 3236 of the mold base 323 does not exceed the outer edge of the wiring board connector 3221, so that a larger area of the top surface 3236 can be obtained for the top side of the mold base 323, and a larger area of the mounting surface can be provided.

In addition, compared to the conventional camera module illustrated in fig. 1B, the mirror base 7 is attached to the outer side of the electronic components of the circuit board 2 through the supporting legs 701, the space thereof is limited, and the bottom surface of the supporting member 370 matching with the filter element 340 provides a larger bonding area with the mold base 323, as shown in fig. 13, the bonding area of the supporting member 370 contacting with the mold base 323 is the first step surface 32361 of the mold base 323, because it is not limited to be located only at the outer side of the electronic components 326 of the circuit board 322, and the mold base 323 does not need to avoid the electronic components 326, so that the larger first step surface 32361 can be provided to support the supporting member 370. So that the supporting member 370 can be more firmly combined with the mold base 323 and the adhesion area is increased, the inclination of the supporting member 370, which may affect the image quality, can be more effectively prevented. Also in this embodiment, the supporting member 370 is supported only on the first step surface 32361, and compared to the conventional lens holder 7 which needs to support the outer side of the electronic component 326, the outer edge of the conventional lens holder is farther from the optical axis X, and the conventional lens holder 7 having a ring-shaped top surface needs a larger area.

In addition, like fig. 67, the combination of the mold base 323 and the supporting member 370 can replace the conventional lens holder 7 in fig. 1B, and the mold base 323 has a greater connection strength because it is integrally combined with the circuit board 322, and can provide a stronger support for the lens 310 above or the lens assembly having the driver 330 or the lens barrel. That is, the stress applied to the mold base 323 by the upper lens 310, or the actuator 330 or the lens barrel can be directly transmitted to the circuit board 322 through the mold base 323. Also, since the mold base 323 and the wiring board 322 are integrally encapsulated, the bonding is more secure and the stress can be more effectively dispersed.

Moreover, in the embodiment illustrated in fig. 68, the second step surface 32361 is used for supporting the driver 330, and the top surface 3701 of the support member 370 can provide an overflow surface for the adhesion between the driver 330 and the second step surface 32361, i.e. the adhesive between the driver 330 and the second step surface 32361 can extend to the top surface 3701 of the support member 370, which is equivalent to that the mold base 323 and the support member 370 together can provide a more firm supporting effect for the driver 330.

Similarly, in this embodiment, the combination of the support 370 and the molded base 323 replaces the conventional mirror base 7 of FIG. 1B, such that the thickness of the support 370 is significantly reduced relative to the conventional mirror base 7 to which the filter element is mounted, and the thickness of the support 370 of the present invention is below 0.7 mm.

As shown in fig. 69 to 71, is a camera module according to a twenty-third preferred embodiment of the present invention. The camera module comprises an integrated base assembly 210, a photosensitive element 220, a lens 230, a filter element lens base 240 and a filter element 250, wherein the integrated base assembly 210, the photosensitive element 220, the filter element lens base 240 and the filter element 250 form a photosensitive assembly.

The lens 230 includes a carrier 231 and one or more lenses 232 assembled in the carrier 231. The integrated base assembly 210 includes an integrated base 211 and a circuit board 212, the integrated base 211 is integrally packaged in the circuit board 212 and the photosensitive element 220, for example but not limited to, integrally packaged in the circuit board 212 and the photosensitive element 220 by molding, and the filter lens holder 240 is mounted in the integrated base 211, so that the combined body formed by the integrated base 211 and the filter lens holder 240 cooperating with each other can replace the lens holder or the bracket of the conventional camera module, and does not need to attach the lens holder or the bracket to the circuit board through glue like in the conventional packaging process. The photosensitive element 220 is operatively connected to the circuit board 212. The photosensitive element 220 is electrically connected to the circuit board 212 of the integrated base assembly 210, the filter element holder 240 is mounted on the integrated base assembly 210, and the lens 230 is located in a photosensitive path of the photosensitive element 220.

The integrated base 211 has an optical window 2111 and a base main body 2112 forming the optical window 2111, the optical window 111 provides a light path for the light sensing element 220, and the base main body 2112 is integrally encapsulated in the circuit board 212 and the light sensing element 220 by molding. In this embodiment, the light window 2111 is a circumferentially closed ring-shaped structure so as to provide a closed inner environment for the lens 230. The circuit board 212 includes a substrate 2121 and a plurality of electronic components 2122 formed on the substrate 2121, for example, mounted by an SMT process, wherein the electronic components 2122 include, but are not limited to, resistors, capacitors, driving devices, and the like. In this embodiment of the present invention, the integrated base 211 is integrally packaged on the substrate 2121 and integrally covers the electronic component 2122, so as to prevent dust and impurities from adhering to the electronic component 2122 to contaminate the photosensitive element 220 and affect the imaging effect, similar to the conventional camera module. It is understood that in alternative embodiments, it is also possible for the electronic component 2122 to be embedded in the substrate 2121. The circuit board 212 is a circuit board, and may be a hard PCB, a soft PCB, a rigid-flex board, a ceramic substrate, or the like.

It should be noted that in some embodiments, the electronic component 2122 is disposed around the photosensitive element 220, and in different embodiments, the arrangement position of the electronic component 2122 may be designed and arranged as required, for example, arranged on one side or two or more sides, and may be matched with the arrangement position of the photosensitive element 220, the arrangement position of the structure where the photosensitive element 220 is connected to the circuit board 212, and the shape of the filter lens holder 240, so as to more reasonably utilize the spatial position on the substrate 2122 and reduce the size of the camera module as much as possible.

Preferably, these electronic components 2122 are arranged on a pair of opposite sides of the photosensitive element 220, i.e. on two wing sides 2121a of the substrate 2121, and the electronic components 2122 are not arranged on two end sides 2121b of the substrate 2121, so that the integrated base 211 has a wider portion corresponding to the two wing sides 2121a of the substrate 2121 and a narrower portion corresponding to the two end sides 2121b of the substrate 2121. In particular, when the circuit board 212 is a rigid-flex board, it includes a hard board portion 21211 and a soft board portion 21212, and the electronic component 2122 is not disposed on the side away from the soft board portion 21212, so that the edge of the substrate 2121 on the side away from the soft board portion 21212 has a reduced size.

The photosensitive element 220 is mounted On the substrate 2121 by, for example, but not limited to, SMT (surface mount technology), and is electrically connected to the substrate 2121 by cob (chip On board) wire bonding. Of course, in other embodiments of the present invention, the photosensitive element 220 may be mounted on the substrate 2121 by other methods, such as embedding, FC (flip chip), etc., and it should be understood by those skilled in the art that the connection and mounting manner of the photosensitive element 220 and the circuit board 212 is not limited by the present invention.

More specifically, the photosensitive element 220 has a photosensitive region 2201 and a non-photosensitive region 2202, the non-photosensitive region 2202 surrounds the photosensitive region 2201, and the integrated base is integrally combined with the circuit board 212 and at least a portion of the photosensitive element 220, the non-photosensitive region 2202. The photosensitive region 2201 is configured to perform a photosensitive action and convert an optical signal into an electrical signal, and the non-photosensitive region 2202 is electrically connected to the circuit board 212 through the connection line 2203 and transmits the electrical signal to the circuit board 212. The lens 230 and the photosensitive element 220 are aligned optically, and the optical axes are the same, so that the light passing through the lens 230 can reach the photosensitive element 220 through the optical window 2111, and further after photoelectric conversion of the photosensitive element 220, an electrical signal can be transmitted to the circuit board 212, so that the image information is collected by the camera module.

As shown in fig. 69 and 70, the filter element 250 of the camera module is used for filtering the light passing through the lens 230. The filter element 250 is exemplified by, but not limited to, an infrared cut filter, a blue glass filter, a wafer level infrared cut filter, a total transmittance sheet, a visible light filter, and the like. The filter element 250 is mounted on the filter element mount 240 and located in the light path of the photosensitive element 220. The camera module may further include a driver 260, such as a voice coil motor, a piezoelectric motor, etc. The lens 230 is mounted on the driver 260 to form a lens assembly 2300, thereby forming a moving focus camera module, i.e., an af (auto focus) camera module. The driver 260 includes at least one pin 261, and the driver 260 is operatively connected to the circuit board 212 through the pin 261. The pin 261 may be one of a single pin, a double pin, a single row pin, or a double row pin. In some of the drawings of the present invention, a two-pin example is illustrated, but not limited. The pin 261 is generally located near the edge, as viewed in cross-section from a location corresponding to line B-B, corresponding to the cross-sectional view of fig. 70, while the pin 261 is not actually visible in the corresponding cross-sectional view, but for ease of understanding and explanation, the presence of the pin 261 is indicated in the corresponding cross-sectional view by dashed lines. It should be understood by those skilled in the art that the type, shape and placement of the pins 261 are not intended to limit the present invention. It is understood that the camera module may be a fixed focus camera module without the above-mentioned actuator 260, i.e. above the integrated base 211 and the filter holder 240 is the lens 230 or the lens assembly 2300 holding the lens with a lens barrel.

As shown in fig. 69 to 71, in this preferred embodiment, the filter element 250 is mounted to the filter element mount 240 and is sunk in the optical window 2111 of the integral base 211. The unitary base 211 of the unitary base assembly 210 has a top surface 2113, the filter element mount 240 is mounted to the top surface 2113 of the unitary base 211, and the actuator 260 is mounted to the filter element mount 240. According to this embodiment of the invention, the top surface 2113 of the integral base 211 extends planarly. In other words, the top surface of the integrated base 211 forms a flat surface without step protrusions, and the filter element holder 240 is mounted on the flat surface. It is worth mentioning that in this manner, the top surface 2113 of the integrated base 211 extends planarly without significant bending angles, so that a more even, burr-free mounting surface can be obtained during the integrated packaging process, such as molding, to provide a flat mounting condition for the filter element base 240.

It is worth mentioning that the filter element 250, such as a blue glass filter, is a relatively fragile and expensive element that is easily broken, and therefore protecting the filter element 250 is also an extremely important aspect in the camera module manufacturing process. In the present invention, the integrated base 211 is manufactured by a molding process such as injection molding or mold pressing, and the material of the filter element mount 240 is not limited as long as it has sufficient strength to carry the filter element 250. Preferably, the filter element holder 240 and the integrated base 211 can be manufactured by different manufacturing processes, such as an injection molding process to manufacture the filter element holder 240, and a transfer molding process to manufacture the integrated base 211, so that different materials can be used, so that the filter element holder 240 and the integrated base 211 have different hardness and different surface flexibility, for example, the filter element holder 240 can have better flexibility, so that when the filter element 250 is mounted on the filter element holder 240, the stress applied to the filter element holder 240 is smaller than that of the filter element holder 211, and the filter element 250 can be mounted more conveniently, and the filter element 250 is prevented from being damaged or cracked. That is, the filter element mount 240 relieves stresses to which the filter element 250 may be subjected, such as stresses to which it is directly bonded to the unitary base 211.

Further, referring to fig. 69 to 71, the filter element holder 240 has a supporting groove 241 on the inner side and an engaging groove 242 on the outer side of the bottom, the supporting groove 241 is used for mounting the filter element 250, and the engaging groove 242 is used for mounting to the integrated base 211. The supporting groove 241 is communicated with the light window 2111. The engaging groove 242 surrounds the bottom periphery of the filter element base 240.

It should be noted that the filter element 250 is mounted in the supporting groove 241, and the relative height between the filter element mount 240 and the filter element 250 is reduced, so that the filter element 250 does not protrude or protrudes less from the filter element mount 240, and the height of the camera module is not increased, and the lens 250 or the driver 260 is not easily touched.

In other words, the supporting groove 241 is implemented as an inner groove, so as to mount the filter element 250 inside the filter element holder 240 and in the light path of the photosensitive element 220. The engaging groove 242 forms an outer ring groove at an outer side of the bottom of the filter element holder 240 so as to be engaged with the integrated base 211, and provides a mounting position for the filter element holder 240 through the integrated base 211.

More specifically, the shape of the engagement groove 242 matches the shape of the integrated base 211, so that the filter element holder 240 is stably mounted to the integrated base 211.

Further, referring to fig. 69 to 71, the filter element holder 240 is preferably a ring-shaped structure including a filter element holder body 243 in a ring-shaped structure, an inwardly extending arm 244 and a sinking arm 245, the sinking arm 245 integrally extending downward from the bottom side of the filter element holder body 243 to facilitate the installation position of the filter element 250 to sink into the optical window 2111. The inwardly extending arm 244 extends integrally laterally from the depressed arm 245 to provide a horizontally oriented mounting location for the filter element 250. It will be appreciated that in a possible variant, the filter element mount 240 does not present a closed annular configuration, such as a U-shaped configuration, and then provides a closed environment by cooperating with the integral base 211.

In other words, the sinking arm 245 integrally extends longitudinally inside the filter holder body 243, the engaging groove 242 is formed at the bottom side of the filter holder body 243 so as to be engaged with the integrated base 211, the inwardly extending arm 244 extends transversely inside the sinking arm 245, and the supporting groove 241 is formed at the top side of the inwardly extending arm 244 so as to support the filter element 250.

In the present invention, the integrated base 211 of the camera module is integrally packaged in the circuit board 212 and at least a part of the non-photosensitive area 2202 of the photosensitive element 220, so that the integrated base 211 has a top surface with a larger area than that of the circuit board 212, so as to provide a mounting surface with a larger size for the filter element lens holder 240.

In addition, as shown in fig. 70, the photosensitive element 220 has a set of photosensitive element connectors 221, the circuit board 212 has a set of circuit board connectors 222, the photosensitive element connectors 221 and the circuit board connectors 222 are connected by a set of connecting wires 223, and the integrated base 211 further embeds the photosensitive element connectors 221, the circuit board connectors 222 and the connecting wires 223. It is to be understood that, in this illustrative specific example of the present invention, the photosensitive-element connectors 221, the wiring-board connectors 222 may be implemented as lands provided protrudingly, respectively. The integrated base 211 is integrally packaged with the circuit board 212 and the photosensitive element 220 and integrally embeds the connecting line 223, thereby preventing stray light from being reflected to the photosensitive element 220 due to the exposed connecting line 223.

The filter element mirror seat 240 is supported on the top surface 2113 of the integrated base 211, and the filter element mirror seat 240 is matched with the integrated base 211 to provide a light path for the photosensitive element 220, wherein an inner edge 21131 of the top surface 2113 of the integrated base 211 is located inside an outer edge 2221 of the circuit board connector 222 and does not exceed the edge 2221 of the circuit board connector 222, so that the inner edge 21131 of the top surface 2113 of the integrated base 211 is closer to the optical axis X of the camera module than the outer edge 2221 of the circuit board connector 222, thereby increasing the area of the top surface 2113 of the integrated base 211 to provide a flat mounting surface with a larger area for optical devices above the camera module. As shown in fig. 72A, the integrated base 211 may have a substantially square ring shape, the inner edge 21131 of the top surface 2113 of the integrated base 211 includes four portions, a distance between a straight line along which a portion of the edge extends and the optical axis X is shown as D1, and a distance between the outer edge 2221 of the circuit board connector 222 and the optical axis X is shown as D2, where D1 is not greater than D2, so that at least a portion of the inner edge 21131 of the top surface 2113 of the integrated base 211 is located further inside the camera module, thereby increasing the area of the top surface 2113 of the integrated base 211. In fig. 72A, all of the portions of the inner edge 21131 of the top surface 2113 of the unitary base 211 are located further inboard of the camera module, thereby increasing the area of the top surface 2113 of the unitary base 211 that can be used to provide a mounting surface.

The optical devices that the flat mounting surface may be used to mount may be, for example, the filter element mount 240, the lens 230, a lens assembly 2300. In the example of fig. 70, the flat mounting surface provided by the area of the top surface 2113 of the unitary base 211 is used to support the filter element mount 240, the actuator 260 and the lens 230 form the lens assembly 2300 supported to the filter element mount 240, and the actuator 260 assembled to the filter element mount 240.

That is, the inner edge 21131 of the top surface 2113 of the integrated base 211 extends toward the direction of the optical axis X of the camera module and beyond the position of the outer edge 2221 of the board connector 222. It is understood that, as shown in fig. 70, a top surface area S of the integrated base 211 corresponding to between the outer edge 22021 of the circuit board connector 222 and the inner edge 21131 of the top surface 2113 of the integrated base 211 is equivalent to an area where the integrated base 211 is integrally packaged only in the circuit board 212 and is not packaged in the photosensitive element 220 and the connecting line 223 which can be increased at least, so that the filter element base 240 can be more stably supported. Also, referring to the case where the integrated base 11 is integrally packaged only with the circuit board 12 and not with the photosensitive element 220 and the connecting line 223 as shown in fig. 7, in such a manner that a space for wire bonding the circuit board 12 and the photosensitive element 20 is required, the integrated base 11 extends obliquely upward from the circuit board 12, which facilitates the mold releasing operation in the molding process, however, allows the area of the top surface of the integrated base 11 to be reduced. Thus, the integral base 211 of this embodiment of the present invention can actually provide an increased top surface area that is significantly greater than the top surface area S described above relative to the integral base 11 of FIG. 7. In this illustrative embodiment of the invention, the top surfaces 2113 of the integral base 211 may both serve as mounting surfaces, i.e., providing a flatter enlarged mounting surface for the filter element mount 240, allowing the filter element mount 240 to be more smoothly assembled to the integral base 211 and enhancing the strength of the connection therebetween.

Compared with the conventional camera module illustrated in fig. 1B, the lens holder 7 is attached to the circuit board 2 through the supporting leg 701, and the bottom surface of the filter element lens holder 240 matching with the filter element 340 provides a larger bonding area with the integrated base 211, as shown in fig. 70, the bonding area of the filter element lens holder 240 contacting with the integrated base 211 is the top surface 2113 of the integrated base 211, so that the filter element lens holder 240 can be more stably combined with the integrated base 211, the bonding area is increased, the inclination of the filter element lens holder 240 can be more effectively avoided, and the imaging quality is improved.

The filter element lens holder 240 may be mounted on the integrated base 211 by means of glue bonding, and the bonding area is large, and the flatness of the filter element lens holder 240 may be adjusted by the thickness of the glue. It should be noted that the filter element 250 may be first attached to the filter element mount 240, and then the filter element mount 240 is attached to the integrated base 211. The filter element lens holder 240 may be formed by an injection molding process, and has a hardness different from that of the integrated base 211, and the size of the filter element 250 is small, so that when the filter element 250 bearing the filter element lens holder 240 is attached to the integrated base 211, the filter element lens holder 240 may provide a stress buffering function, and thus the filter element 250 is not easily broken. Compared with the method of directly attaching the filter element 250 to the integrated base 211, the filter element 250 has a larger size and no stress buffer, so that the filter element 250 is easy to break in the attachment process, and the attachment method has higher requirements on the attachment process.

In addition, the combination body of the integrated base 211 and the filter element lens base 240 can replace the conventional lens base 7 in fig. 1B, the integrated base 211 has a larger connection strength because it is integrally combined with the circuit board 212, and the filter element lens base 240 is a structural member for carrying the filter element 340. The combination of these two parts thus provides greater support for the overlying optical assembly, such as the actuator 260 illustrated in the figure, relative to the mirror mount 7 illustrated in figure 1B. That is, the stress applied to the filter element holder 240 can be transmitted to the integrated base 211 and the circuit board 212 more effectively. Moreover, since the integrated base 211 and the circuit board 212 are integrally packaged, the bonding is more secure, and stress can be more effectively dispersed.

Moreover, the assembly of the filter element mount 240 and the integral base 211 replaces the conventional mount 7 of fig. 1B, so that the thickness of the filter element mount 240 is significantly reduced relative to the conventional mount 7 to which the filter element is mounted, and the thickness of the filter element mount 240 of the present invention is below 0.7 mm.

In addition, in a more preferable scheme, the integrated base 211 has an inner side surface 2114 obliquely extending from the light sensing element 220 to form the light window 2111 having an inner diameter gradually increasing toward a direction away from the light sensing element 220 and an opening gradually increasing. And at the bottom side of the filter element 250, the inner surface 2441 of the inwardly extending arm 244 of the filter element mount 240 extends obliquely and has an increased inner diameter toward the direction adjacent to the light sensing element 220, so that the obliquely extending inner surface 2441 of the inwardly extending arm 244 of the filter element mount 240 can prevent stray light with respect to the vertically extending inner surface. Further, as shown in fig. 72B, below the filter element 250, the filter element mirror holder 240 and the integrated base 211 form an inner chamfered structure, so that when the stray light L1 reaches the inner side surface 2114 of the integrated base 214, it is reflected to further reach the inclined inner surface 2441 of the inwardly extending arm 244 of the filter element mirror holder 240, and is further reflected to avoid the light L1 from reaching the photosensitive element 220 to affect the imaging quality.

It is worth mentioning that, in the present invention, the surface reflectivity of the integral base 211 is below 5%, and the wavelength range of the reflected light is 435 to 660 nm. That is, most of the light incident on the surface of the integrated base 211 cannot be reflected to form interference stray light reaching the light sensing element 220, thereby further reducing the influence of the reflected stray light.

It is worth mentioning that in the molding and packaging process, the area of the filter element is larger or increased compared to the area required by the conventional lens holder because the inward extending arm 244 cannot be formed, whereas in the present invention, the inward extending arm 244 extends inward, so that the required area of the filter element 250 is reduced, and the advantages of the filter element lens holder 240 and the advantages of the integrated package are combined.

For example, referring to fig. 70, the distance between the inwardly extending arms 244 on opposite sides is marked as L, and the diameter of the filter element 250 only needs to be larger than L and is mounted on the inwardly extending arms 244 without being mounted on the base body 2112, so that the required area of the filter element 250 is reduced. In this embodiment of the invention, the filter element 250 is disposed on the filter element bezel 240 such that the outer edge 2501 of the filter element 250 is positioned inward of the inner edge 21131 of the top surface 2113 of the unitary base 211, such that assembly of the filter element 250 to the filter element bezel 240 reduces the area of the filter element 250 relative to the unitary base 211

In this embodiment of the present invention, the extension distance of the sinking arm 245 affects the sinking depth of the filter element 250 in the optical window 2111, and the extension distance of the inward extending arm 244 affects the size of the area of the filter element 250 mounted. For example, when the extension distance of the sinking arm 245 is larger, the position of the filter element 250 in the optical window 2111 sinks downwards, the distance from the photosensitive element 220 is smaller, and the back focal length of the corresponding camera module is smaller; when the extension distance of the inner extension arm 244 is longer, the area of the filter element 250 is smaller, so that the filter element 250 is more suitable to be obtained, the installation is convenient, and the cost of the camera module is reduced. Of course, the extending distance of the sinking arm 245 needs to be combined with the imaging effect of the camera module, for example, dark spots such as dust images are not generated on the basis of reducing the back focus; the extending distance of the inner extending arm 244 needs to consider the camera module light path, the photosensitive area 2201 and the non-photosensitive area 2202 of the photosensitive element 220, the remaining width of the circuit board 212, and other factors, for example, when the inner extending arm 244 extends inward, the inner extending arm 244 does not block the photosensitive area 2201 of the photosensitive element 220 and does not block the entering light flux too much under the condition that the filter element 250 is small.

It should be noted that, in this embodiment of the present invention, the integrated base 211 is packaged on the upper surface of the circuit board 212, while in other embodiments of the present invention, the integrated base 211 may extend to the side and/or bottom surface of the circuit board 212, and it should be understood by those skilled in the art that the integrated forming scope of the integrated base 211 is not limited by the present invention.

In the above embodiment of the present invention, the filter lens holder 240 is mounted on the integrated base 211, the actuator 260 is mounted on the filter lens holder 240, that is, the filter lens holder 240 is disposed between the actuator 260 and the integrated base 211, the imaging module formed is a moving focus imaging module, and the integrated base 211 and the filter lens holder 240 integrally combined with the circuit board 212 and the photosensitive element 220 can provide a strong support for the lens assembly 2300 having the actuator 260 and the lens 230 thereon. As shown in fig. 73, the camera module does not include the driver 260, which forms a fixed focus camera module, the lens assembly 2300 formed by the lens 230 and a fixed lens barrel 270 is directly mounted on the filter element lens holder 240, and the integrated base 211 and the filter element lens holder 240 integrally combined with the circuit board 212 and the photosensitive element 220 can provide a strong support for the lens assembly 2300 having the fixed lens barrel 270 and the lens 230 thereon. As shown in fig. 74A, the lens 230 is directly mounted on the filter element mount 240, and the integrated base 211 and the filter element mount 240 integrally coupled to the circuit board 212 and the light sensing element 220 can provide a strong support for the lens 230 above.

As shown in fig. 74B, in this modified embodiment, the filter element holder 240 may have a plurality of step surfaces on the top side, and in the structure shown in the figure, the filter element holder 240 has three

step surfaces

2401, 2402 and 2403, and has a support groove 241 and an assembly groove 248, the support groove 241 is used for mounting the filter element 250 so that the filter element 250 is supported on the first step surface 2401, the assembly groove 248 is located on the outer side of the support groove 241 so that the lens 230 is assembled on the second step surface 2402, so that the position of the lens 230 is further lowered to reduce the overall height of the camera module, and the protruding step portion corresponding to the outermost step surface 2403 located on the outer side of the lens 230 can play a role in limiting the lens 230. It is understood that the assembly groove 248 may be used to assemble the lens assembly 2300 with the driver 260 or the fixed barrel 270 in another variant embodiment.

In a further variant embodiment of the invention, as shown in fig. 75A, both the filter element mount 240 and the actuator 260 are mounted to the top surface 2113 of the integral base 211. Further, the filter element mirror mount 240 is mounted at a position inside the top surface 2113 of the unitary base 211, and the actuator 260 is mounted at a position outside the top surface 2113 of the unitary base 211, such that the actuator 260 and the filter element mirror mount 240 cooperatively dispense the top surface 2113 of the unitary base 211. In a further variant embodiment of the invention, as shown in fig. 75B, both the filter element mount 240 and the fixed barrel 270 are mounted to the top surface 2113 of the integral base 211. Further, the filter element mount 240 is mounted at a position inside the top surface 2113 of the unified base 211, and the fixed barrel 270 is mounted at a position outside the top surface 2113 of the unified base 211, so that the fixed barrel 270 and the filter element mount 240 cooperatively distribute the top surface 2113 of the unified base 211. In a further variant embodiment of the invention, as shown in fig. 75C, both the filter element mount 240 and the lens 230 are mounted to the top surface 2113 of the integral base 211. Further, the filter mirror mount 240 is mounted at a position inside the top surface 2113 of the unitary base 211, and the lens 230 is mounted at a position outside the top surface 2113 of the unitary base 211, so that the lens 230 and the filter mirror mount 240 cooperatively distribute the top surface 2113 of the unitary base 211. That is, the mounting surface provided by the top surface 2113 of the integral base 211 is fully utilized and its area is capable of supporting two optical devices.

More specifically, in fig. 75A to 75C, the inner edge 21131 of the top surface 2113 of the integrated base 211 is closer to the optical axis X of the camera module than the outer edge 2221 of the circuit board connector 222, that is, the inner edge 21131 of the top surface 2113 of the integrated base 211 is located at a more inner side position, and in the horizontal direction perpendicular to the optical axis X illustrated in the drawing, the inner edge 21131 of the top surface 2113 of the integrated base 211 and the outer edge 2221 of the circuit board connector 222 have a predetermined distance therebetween, so as to increase the area of the top surface 2113 of the integrated base 211, thereby providing a flat mounting surface with a larger area for the optical device above the camera module. In this embodiment, the area of the top surface 2113 is utilized as a mounting surface, and the optical devices that the flat mounting surface may be used to mount may be, for example, the filter element mount 240 and the driver 260 or the fixed barrel 260 or the lens 230.

In the example of FIG. 69, the flat mounting surface provided by the area of the top surface 2113 of the unitary base 211 is used to support the filter element mount 240, the actuator 260 and the lens 230 form a lens assembly 2300, and the actuator 260 is assembled to the filter element mount 240. In the example shown in fig. 75A to 75C, the top surface 2113 of the integrated base 211 provides a portion of the mounting surface 21131 on the inner side for mounting the filter element mount 240, and the integrated base 211 provides a portion of the mounting surface 21132 on the outer side for mounting the driver 260 or the fixed barrel 260 or the lens 230. Thus, the top surface 2113 of the integrated base 211 can provide a sufficiently large attachment surface for the filter element mount 240 and the driver 260 or the fixed barrel 260 or the lens 230 at the same time.

That is, the integrated base 211 of the present invention is integrally combined with the circuit board 212 and the photosensitive element 220, and the integrated base 211 integrally embeds the photosensitive element connector 221, the circuit board connector 222 and the connecting wire 223. In the embodiment illustrated in fig. 2 to 56, the integrated base 11 does not embed the corresponding photosensitive-element connectors, the circuit-board connectors and the connecting wires, so that a large mounting surface is formed on the top side of the integrated base 11 by the spatial position above the photosensitive-element connectors, the circuit-board connectors and the connecting wires. Also, it is understood that the integrated base 11 is usually made by molding process of upper and lower molds, and in the embodiment shown in fig. 2 to 56, not only the space for wire bonding the circuit board 12 and the photosensitive element 20 is left, but also the further modification is that, for the convenience of demolding, the inner surface of the integrated base 11 is usually extended obliquely to form an optical window with an opening gradually increasing from bottom to top, as shown in fig. 7, which may cause the area of the top surface of the integrated base 11 to be further reduced and not provide a sufficient mounting area. In this embodiment of the present invention, the inner surface 2114 of the integrated base 211 is also obliquely extended to facilitate the mold releasing operation of the molding process and to avoid stray light, and the obliquely extended inner surface 2114 of the integrated base 211 causes the top area of the integrated base 211 to tend to be reduced. In contrast to the embodiment shown in fig. 7, the integrated base 211 embeds the photosensitive element connector 221, the circuit board connector 222 and the connecting wire 223, thereby making full use of the space above the photosensitive element connector 221, the circuit board connector 222 and the connecting wire 223, and making the portion of the integrated base 211 corresponding to the inner surface 2114 extending obliquely from the photosensitive element 220 mainly concentrate above the photosensitive element connector 221, the connecting wire 223 and the circuit board connector 222, so that the end of the integrated base 211 along the inner surface 2114 extending obliquely away from the photosensitive element 220, i.e. the position corresponding to the inner edge 21131 of the top surface 2113, in the horizontal direction perpendicular to the optical axis X shown in the figure, does not exceed the outer edge 2221 of the circuit board connector 222, thereby making it possible to obtain a larger area of the top surface 2113 for the top side of the integrated base 211, thereby providing a larger area of flat mounting surface to mount the filter element mount 240 or to mount the filter element mount 240 and the lens 230 or the lens assembly 2300.

In addition, in the structure of this embodiment, the lens 230 or the lens assembly 2300 may be directly attached to the flat top surface 2113 of the integrated base 211, which may reduce assembly tolerances and offset of the lens 230 or the lens assembly 2300 relative to the assembly to the filter mount 240.

As shown in fig. 76, in accordance with another variation of the above-described preferred embodiment of the present invention, the optical element mount 240 includes at least one limiting protrusion 246, and the limiting protrusion 246 extends at least partially and convexly upward from the top of the main body of the optical filter element mount 240. Further, the limiting protrusion 246 extends upward from the top surface of the filter element holder main body 243 at least partially and convexly, so as to limit the mounted element and prevent dust or light from entering the inside of the camera module. The position-limiting protrusion 246 limits the driver 260 or the lens 230 by way of example but not limitation. More specifically, in an embodiment, the limiting protrusion 246 is disposed in the middle of the main body 243 of the mirror base, and divides the top of the main body 243 of the mirror base into two parts, the outer side is used for mounting the driver 260, and the lens 230 is located at the inner side. In this manner, the stop tab 246 may position the driver 260, reducing the deflection of the driver 260. And the glue mounting the actuator 260 can be prevented from overflowing to the inside to contaminate the lens or the internal components during the assembly process. Preferably, the limit projection 426 may be an annular projection, thereby integrally positioning the driver 260 to block the glue from overflowing to the inside.

As shown in fig. 77, according to another modified embodiment of the above preferred embodiment of the present invention, the integrated base 211 is formed with a mounting groove 2115 on the top side, and the filter element holder 240 is mounted to the mounting groove 2115. More specifically, the integrated base 211 may have a plurality of step surfaces at a top side, and as shown in fig. 77, the top surface 2113 of the integrated base 211 has a first step surface 2113a at an inner side and a second step surface 2113b at an outer side, and the mounting groove 2115 is formed at the top side of the first step surface 2113a and the inner side of the second step surface 21132. The first step surface 2113a and the second step surface 2113b of the integrated base 211 serve as a part of a flat mounting surface of the integrated base 211 formed by a molding process, respectively, to support the filter element mount 240 and the driver 260, respectively.

More specifically, the first stepped surface 2113a of the integrated base 211 is engaged with the engaging groove 242 on the bottom outside of the filter element holder 240, so that the filter element holder main body 243 of the filter element holder 240 is supported to be accommodated in the mounting groove 2115. In this embodiment, when the filter element holder 240 is mounted to the mounting groove 2115, the top surface of the filter element holder 240 coincides with the top surface of the base-body integrated base 211, so that the filter element holder 240 does not protrude from the base body 2112F and the lens 230 and the actuator 260 located above are not easily touched. In a further variant embodiment, the upper surface of the filter element mount 240 may protrude slightly above the top surface 2113 of the unitary base 211, so as to cooperate to retain the actuator 260 and prevent glue from overflowing to the inside when the actuator 260 is installed.

In this embodiment, the integral base 211 includes an annular raised step 2116 projecting from the base body 2112. The raised step 2116 extends partially upward from the base body 2112 to form the mounting slot 2115 on the inside thereof. The top side of the projecting step 2116 forms the second step face 2113 b. The driver 260 is at least partially mounted to the raised step 2116, thereby forming a moving focus camera module. It is understood that in other embodiments, the lens 230 or the fixed barrel 270 is at least partially mounted on the raised step 2116 to form a focus camera module.

In this embodiment of the present invention, the photosensitive element 220 and the wiring board 212 are connected by the photosensitive element connector 221, the wiring board connector 222 and the connecting line 223, and the photosensitive element connector 221, the wiring board connector 222 and the connecting line 223 are connected to be embedded in the integrated base 211. Wherein an inner edge of the first step face 2113a is an inner edge of the top surface 2113 of the integrated base 211.

The inner edge 21131 of the first step surface 2113a at the innermost side of the top surface 2113 of the integrated base 211 is closer to the optical axis X of the camera module with respect to the outer edge 2221 of the circuit board connector 222, that is, the inner edge 21131 of the first step surface 2113a at the innermost side of the top surface 2113 of the integrated base 211 is located at a more inner side position, and in the horizontal direction of the vertical optical axis X illustrated in the drawing, a predetermined distance is provided between the inner edge 21131 of the first step surface 2113a at the innermost side of the top surface 2113 of the integrated base 211 and the outer edge 2221 of the circuit board connector 222, so as to increase the area of the top surface 2113 of the integrated base 211, and provide a flat mounting surface with a larger area for an optical device above the camera module. In this implementation, the area of the top surface 2113 is utilized as a mounting surface, and the optical devices that the flat mounting surface may be used to mount may be, for example, the filter element mount 240 and the actuator 260. More specifically, the top surface 2113 of the integrated base 211 provides a first stepped surface 2113a at an inner side position shifted down as a first partial mounting surface for mounting the filter element mirror base 240, and the integrated base 211 provides a second stepped surface 2113b at an outer side position on a top side of the raised step 2116 as a second partial mounting surface for mounting the driver 260. Such that the first step surface 2113a and the second step surface 2113b of the top surface 2113 of the integrated base 211 can simultaneously provide a sufficiently large mounting surface for the filter element mirror mount 240 and the driver 260. The first step surface 2113a of the integrated base 211 above the photosensitive element attachment 221, the circuit board attachment 222, and the connection line 223 is fully utilized, thereby providing a mounting surface for mounting the filter element base 240. In addition, the glue bonding between the driver 330 and the second stepped surface 32361 can extend to the top surface of the filter mount 240, which is equivalent to the integral base 211 and the filter mount 240 together providing a more secure support for the driver 260. It is to be understood that, as another conceivable modification, the lens barrel 270 or the lens 230 is directly attached to the second step surface 2113b of the top surface 2113 of the integrated base 211, and the top surface 2113 of the integrated base 211 can simultaneously provide a sufficiently large attachment area for the filter element holder 240 and the lens barrel 270 or the lens 230.

Fig. 78 to 80 show the camera module according to the twenty-fourth preferred embodiment of the present invention, wherein the camera module includes an integrated base assembly 210, a photosensitive element 220, a lens 230, a filter element holder 240 and a filter element 250, wherein the integrated base assembly 210, the photosensitive element 220, the filter element holder 240 and the filter element 250 constitute a photosensitive assembly. The integrated base assembly 210 comprises an integrated base 211 and a circuit board 212, the integrated base 211 is integrally packaged on the circuit board 212 and the photosensitive element 220, and the filter element lens base 240 is mounted on the integrated base 211, so that the integrated base 211 and the filter element lens base 240 are matched with each other to replace a lens base or a support of a traditional camera module, and the lens base or the support does not need to be attached to the circuit board through glue in a similar traditional packaging process. The photosensitive element 220 is operatively connected to the circuit board 212. The photosensitive element 220 is electrically connected to the circuit board 212 of the integrated base assembly 210, the filter element holder 240 is mounted on the integrated base assembly 210, and the lens 230 is located in a photosensitive path of the photosensitive element 220. The integrated base 211 has an optical window 2111 and a base main body 2112 forming the optical window 2111, the optical window 111 provides a light path for the light sensing element 220, and the base main body 2112 is integrally encapsulated in the circuit board 212 and the light sensing element 220 by molding.

The circuit board 212 includes a substrate 2121 and a plurality of electronic components 2122 formed on the substrate 2121, where the electronic components 2122 include, but are not limited to, resistors, capacitors, driving devices, and the like. In this embodiment of the present invention, the integrated base 211 is integrally packaged on the substrate 2121 and integrally covers the electronic component 2122. Moreover, in some embodiments, the electronic component 2122 is disposed around the photosensitive element 220, and in different embodiments, the disposition position of the electronic component 2122 may be designed and arranged as needed, for example, disposed on one side or two or more sides, and may be matched with the disposition position of the photosensitive element 220, the disposition position of the structure connecting the photosensitive element 220 and the circuit board 212, and the shape of the filter element lens holder 240, so as to more reasonably utilize the spatial position on the substrate 2122 and reduce the size of the camera module as much as possible.

The photosensitive element 220 has a photosensitive region 2201 and a non-photosensitive region 2202, the non-photosensitive region 2202 surrounds the photosensitive region 2201, and the integrated base is integrally combined with the circuit board 212 and at least a part of the photosensitive element 220, the non-photosensitive region 2202.

The filter element holder 240 has a supporting groove 241, and the filter element 250 is mounted in the supporting groove 241, so that the filter element 250 is moved downward. It is understood that the filter element holder 240 is a ring structure with a through hole in the middle, and after the filter element 250 is assembled, the filter element 250 can allow the light transmitted through the lens 230 to pass through the filter element 250 and reach the photosensitive element 220.

Further, the filter element holder 240 includes an annular filter element holder main body 243 and an annular inward extending arm 244, and the inward extending arm 244 extends transversely and integrally inward from a lower portion of the filter element holder main body 243 to form the supporting groove 241. The filter element mount body 243 is supported by the integral base 211. The filter element mount 240 does not include the sinking arm 245 in the above embodiments, and does not have the engaging groove 242, and the bottom side of the filter element mount 240 is a flat surface.

In this preferred implementation, the filter element 250 is mounted to the filter element mount 240, as shown in fig. 78-80. The unitary base 211 of the unitary base assembly 210 has a top surface 2113, the filter element mount 240 is mounted to the top surface 2113 of the unitary base 211, and the lens 230 is mounted to the filter element mount 240. According to this embodiment of the invention, the top surface 2113 of the integral base 211 extends planarly. In other words, the top surface of the integrated base 211 forms a flat surface without step protrusions, and the filter element holder 240 is mounted on the flat surface. It is worth mentioning that in this manner, the top surface 2113 of the integrated base 211 extends planarly without significant bending angles, so that a more even, burr-free mounting surface can be obtained during the integrated packaging process, such as molding, to provide a flat mounting condition for the filter element base 240.

In addition, as shown in fig. 78 to 80, the photosensitive element 220 has a photosensitive element connector 221, the circuit board 212 has a circuit board connector 222, the photosensitive element connector 221 and the circuit board connector 222 are connected by a set of connecting wires 223 therebetween, and the integrated base 211 further embeds the photosensitive element connector 221, the circuit board connector 222 and the connecting wires 223. It is to be understood that, in this illustrative specific example of the present invention, the photosensitive-element connectors 221, the wiring-board connectors 222 may be implemented as lands provided protrudingly, respectively.

The filter lens holder 240 is supported on the top surface 2113 of the integrated base 211, and the filter lens holder 240 fits the integrated base 211 to provide a light path for the photosensitive element 220, wherein an inner edge 21131 of the top surface 2113 of the integrated base 211 is closer to the optical axis X of the camera module than an outer edge 2221 of the circuit board connector 222, so as to increase the area of the top surface 2113 of the integrated base 211, and provide a larger area of flat mounting surface for the optical device above the camera module. The flat mounting surface may be used to mount the optical device-for example in this embodiment, the area of the top surface 2113 of the integral base 211 provides the flat mounting surface for supporting the filter element bezel 240.

That is, the inner edge 21131 of the top surface 2113 of the integrated base 211 extends toward the direction of the optical axis X of the camera module and may pass over the position of the outer edge 2221 of the board connector 222. It is understood that, as shown in fig. 78 to 80, the top surface area S of the integrated base 211 corresponding to the space between the outer edge 22021 of the circuit board connector 222 and the inner edge 21131 of the top surface 2113 of the integrated base 211 corresponds to an area at which the structure in which the integrated base 211 is integrally packaged only at the edge of the circuit board 212 without being packaged at the photosensitive element 220 and the connecting wire 223 can be increased, so that the filter element holder 240 can be more stably supported. Also, referring to the case where the integrated base 11 is integrally packaged only at the edge of the wiring board 12 as shown in fig. 8A, the integrated base 211 of this embodiment of the present invention can actually provide an increased top surface area significantly larger than the above-mentioned top surface area S with respect to the integrated base 11 of fig. 8A. In this illustrative embodiment of the invention, the top surface 2113 of the integral base 211 serves as a mounting surface, i.e., provides a flatter enlarged mounting surface for the filter element mount 240, allowing the filter element mount 240 to be more smoothly assembled to the integral base 211 and enhancing the strength of the connection therebetween.

Compared with the conventional camera module illustrated in fig. 1B, the lens holder 7 is attached to the circuit board 2 through the support leg 701, and the bottom surface of the filter lens holder 240 matching with the filter element 340 provides a larger bonding area with the integrated base 211, as shown in fig. 78 to 80, the bonding area of the filter lens holder 240 contacting with the integrated base 211 is the top surface 2113 of the integrated base 211, so that the filter lens holder 240 can be more stably combined with the integrated base 211, the bonding area is increased, and the inclination of the filter lens holder 240 can be more effectively avoided to improve the imaging quality.

In addition, the combination body of the integrated base 211 and the filter element lens base 240 can replace the conventional lens base 7 in fig. 1B, the integrated base 211 has a larger connection strength because it is integrally combined with the circuit board 212, and the filter element lens base 240 is a structural member for carrying the filter element 340. The combination of these two parts thus provides greater support for the overlying optical components, such as the lens 230 illustrated in the figure, relative to the lens holder 7 illustrated in figure 1B. That is, the stress applied to the filter element holder 240 can be transmitted to the integrated base 211 and the circuit board 212 more effectively. Moreover, since the integrated base 211 and the circuit board 212 are integrally packaged, the bonding is more secure, and stress can be more effectively dispersed.

In addition, in a more preferable scheme, the integrated base 211 has an inner side surface 2114 obliquely extending from the light sensing element 220 to form the light window 2111 having an inner diameter gradually increasing toward a direction away from the light sensing element 220 and an opening gradually increasing. Whereas at the bottom side of the filter element 250, the inner surface 2441 of the inwardly extending arm 244 of the filter element mirror mount 240 extends obliquely and has an increasing inner diameter toward the direction adjacent to the light sensing element 220, so that, as shown in fig. 80, below the filter element 250, the filter element mirror mount 240 and the integral base 211 form an inner chamfered structure, so that when stray light L2 reaches the inner side surface 2114 of the integral base 214, it is reflected further to the inclined inner surface 2441 of the inwardly extending arm 244 of the filter element mirror mount 240 and is further reflected to avoid light L2 from reaching the light sensing element 220 to affect the imaging quality.

As shown in fig. 81, according to another modified embodiment of the above-described embodiment of the present invention, the integrated base 211 is formed at the top side with a mounting groove 2115, and the filter element mirror holder 240 is mounted to the mounting groove 2115. More specifically, the integrated base 211 may have a plurality of step surfaces at a top side, and as shown in fig. 81, the top surface 2113 of the integrated base 211 has a first step surface 2113a at an inner side and a second step surface 2113b at an outer side, and the mounting groove 2115 is formed at the top side of the first step surface 2113a and the inner side of the second step surface 21132. The first step surface 2113a and the second step surface 2113b of the integrated base 211 are respectively used as a part of a flat mounting surface formed by a molding process of the integrated base 211 to respectively support the filter element mount 240 and the lens 230.

More specifically, the first stepped surface 2113a of the integrated base 211 supports the flat bottom surface of the filter element holder 240 such that the filter element holder 240 is received in the mounting groove 2115. In this embodiment, when the filter element holder 240 is mounted to the mounting slot 2115, the top surface of the filter element holder 240 and the top surface of the base body 2112C are substantially coincident, so that the filter element holder 240 does not protrude above the top surface 2113 of the unitary base 211 and the lens 230 positioned above is not easily touched. Of course, in the variant embodiment illustrated in fig. 82, the upper surface of the filter element mount 240 may protrude slightly above the top surface 2113 of the integral base 211, so as to cooperate to limit the lens 230 and prevent the glue from overflowing to the inside when the lens 230 is mounted.

In this embodiment, the integral base 211 includes an annular raised step 2116 projecting from the base body 2112. The raised step 2116 extends partially upward from the base body 2112 to form the mounting slot 2115 on the inside thereof. The top side of the projecting step 2116 forms the second step face 2113 b. The lens 230 is at least partially mounted to the raised step 2116, thereby forming a fixed focus camera module.

In this embodiment of the present invention, the photosensitive element 220 and the wiring board 212 are connected by the photosensitive element connector 221, the wiring board connector 222 and the connecting line 223, and the photosensitive element connector 221, the wiring board connector 222 and the connecting line 223 are connected to be embedded in the integrated base 211. Wherein an inner edge of the first step face 2113a is an inner edge 21131 of the top surface 2113 of the unitary base 211.

The inner edge 21131 of the first step surface 2113a at the innermost side of the top surface 2113 of the integrated base 211 is closer to the optical axis X of the camera module with respect to the outer edge 2221 of the circuit board connector 222, that is, the inner edge 21131 of the first step surface 2113a at the innermost side of the top surface 2113 of the integrated base 211 is located at a more inner side position, and in the horizontal direction of the vertical optical axis X illustrated in the drawing, a predetermined distance is provided between the inner edge 21131 of the first step surface 2113a at the innermost side of the top surface 2113 of the integrated base 211 and the outer edge 2221 of the circuit board connector 222, so as to increase the area of the top surface 2113 of the integrated base 211, and provide a flat mounting surface with a larger area for an optical device above the camera module.

It is understood that the end of the portion of the inner surface of the integrated base 211 extending obliquely from the photosensitive element 220 toward the side away from the photosensitive element 220, i.e., the inner edge of the first step surface 2113a, does not extend beyond the outer edge 2221 of the circuit board connector 222, thereby increasing the area of the top surface 2113 of the integrated base 211.

In this embodiment, the area of the top surface 2113 is utilized as a mounting surface, and the optical devices that the flat mounting surface may be used to mount may be, for example, the filter element mount 240 and the lens 230. More specifically, the top surface 2113 of the integrated base 211 provides a first stepped surface 2113a at a position shifted down at an inner side as a first partial mounting surface for mounting the filter element bezel 240, and the integrated base 211 provides a second stepped surface 2113b at a top side of the raised step 2116 at an outer side as a second partial mounting surface for mounting the lens 230. Such that the first step 2113a and the second step 2113b of the top surface 2113 of the integrated base 211 can simultaneously provide a sufficiently large mounting surface for the filter element mount 240 and the lens 30. The first step surface 2113a of the integrated base 211 above the photosensitive element attachment 221, the circuit board attachment 222, and the connection line 223 is fully utilized, thereby providing a mounting surface for mounting the filter element base 240. In addition, the adhesive glue between the actuator 330 and the second stepped surface 32361 can extend to the top surface of the filter mount 240, which is equivalent to the integral base 211 and the filter mount 240 together providing a more secure support effect for the lens.

That is, the mounting groove 2115 is an open communication groove and is not a closed structure. The filter element mount 240 is mounted to the mounting slot 2115. More specifically, in this embodiment, a pair of opposite sides of the mounting groove 2115 are provided with the above-mentioned notch 2117, respectively, i.e., the multi-sectional protruding step 2116 includes steps on a pair of opposite sides. It will be appreciated that in alternative variations, the notch 2117 may be provided such that the multi-part raised step 2116 comprises a three-part step and is of a generally U-shaped configuration. In another modified embodiment, two of the notches 2117 may be adjacently disposed, and the multi-part protruding step 2116 includes two steps and has a substantially L-shaped configuration.

In this embodiment, the filter element holder 240 is attached to the mounting groove 2115 of the integrated base, and the filter element holder main body 243 of the filter element holder 240 includes an engaging portion 2431 and two extensions 2432, the engaging portion 2431 is located in the mounting groove 2115, and the extensions 2432 are used for filling the gap 2117. In other words, the extension 2432 extends into the notch 2117, such that the notch 2117 is filled, thereby forming a closed inner environment, such that the light window 2111 is in a sealed state.

As shown in fig. 85, is an image pickup module according to another modified embodiment of the above preferred embodiment of the present invention. Unlike the preferred embodiment described above, the filter element mount 240 includes an upwardly extending wall 247, and the upwardly extending wall 247 extends upwardly and convexly from the filter element mount body 243 to form a limiting cavity 2471. The retaining cavity 2471 is used to retain a mounted component, such as but not limited to a lens assembly 2300 or a lens 230, such as the lens assembly 2300 having the driver 260 and the lens 230.

That is, when the camera module is assembled, the lens assembly 2300 is mounted in the limiting cavity 2471 of the filter element mount 240, and the lens assembly 2300 is limited so that the optical axis of the lens assembly 2300 coincides with the optical axis of the photosensitive element 220. The size of the spacing cavity 2471 may be determined according to the size of the component to be mounted.

In other words, the extending wall 247 has a frame constraint function, so that when the components such as the driver 260 or the lens 230 are mounted on the filter holder 240, excessive deviation is not generated, and the consistency of the optical system of the camera module is ensured. Meanwhile, the upper extension wall 247 may protect the mounted components, such as the lens assembly 2300 or the lens 230, from external unnecessary touch, so that the driver 260 or the lens 230 is stably mounted. And can shelter from outside dust and get into inside the module of making a video recording.

Further, when the camera module is a moving focus camera module, the filter lens holder 40 has at least one pin port for passing through the pin 261 of the driver 260.
