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 and rapidly increased, and the camera module is increasingly required to be multifunctional, light, thin and small to meet the development of the intelligent electronic devices, so that the intelligent electronic devices can be thinner and meet the imaging requirements of the devices on the camera module. 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. Compared with the driving COB packaging technology, the molding packaging technology has a plurality of 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 method, 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 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 parts can affect the area of the circuit board, and the thickness 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 13, a lens 30 and a filter element holder 40.

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 13 is operatively connected to the circuit board 12.

The photosensitive element 13 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 13.

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 light sensing element 13, 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 ring 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 13 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 13, but 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 13, the subsequent disposition position of the electrical connection element 133, 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 13 includes a front surface 131 and a back surface 132, the front surface 131 is opposite to the lens 30 for performing a photosensitive function, and the back surface 132 is opposite to the lens 30 for being mounted on the upper surface 1211 of the substrate 121. The photosensitive element 13 is electrically connected to the substrate 121 through at least one electrical connecting element 133. The electrical connection element 133 is exemplified by, but not limited to, a gold wire, a silver wire, a copper wire, an aluminum wire. The electrical connection elements 133 may be disposed on one side, two sides, three sides, or four sides of the photosensitive element 13, and in some drawings of the present invention, an embodiment in which the electrical connection elements 133 are disposed on four sides is taken as an example for illustration, but in other embodiments, the electrical connection elements 133 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, position, and type of the disposed electrical connection elements 133 are not a limitation of the present invention.

The photosensitive element 13 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 13 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 13 and the circuit board 12 is not limited by the present invention.

More specifically, the front surface 131 of the photosensitive element 13 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 133 to transmit the electrical signal to the circuit board 12. The lens 30 and the photosensitive element 13 are arranged in optical alignment, and the optical axes are the same, so that the light passing through the lens 30 can reach the photosensitive element 13 through the optical window 111, and further after photoelectric conversion of the photosensitive element 13, 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 13. 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 13.

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 13. 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 13 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 integrally extends in the longitudinal direction inside the filter holder body 43, the engaging groove 42 is formed at the bottom sides of the filter holder body 43 and the sinking arm 45 so as to be engaged with the integrated base 11, the inwardly extending arm 44 transversely extends inside the sinking arm 45, and the supporting groove 41 is formed at the top sides of the filter holder body 43 and the inwardly extending arm 44 so as to support the filter element 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 13. 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, since the inwardly extending arms 44 cannot be formed, the area of the filter element required is larger, or increased relative to the area required by the conventional lens holder, whereas in the present invention, the inwardly extending arms 44 extend inwardly, thereby reducing the required area of the filter element 50, and thus combining the advantages of the filter element lens holder 40 with the advantages of the integral package.

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 between 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 optical window 111, the distance from the photosensitive element 13 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 consider 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 13, 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 13 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 with different widths, and accordingly, the filter element lens holder main body 43 may be provided with a corresponding groove or protruding position, or the lengths of the inward extending arms 44 are different to adapt to the shape of the integrated base 11, to adapt to the position of the photosensitive element 13, and to facilitate installation of the filter element 50.

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 13 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 13 is received in the inner groove to reduce the height of the photosensitive element 13 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 light sensing element 13 is accommodated in the through hole, so that the relative positions of the light sensing element 13 and the substrate 121 are adjustable, such as the upper surface 1211 or the lower surface 1212 being uniformly arranged. In another embodiment, the substrate 121 may have a via with a stepped structure, and the photosensitive element 13 is flip-chip mounted in the via. In another embodiment, the base plate 121 may have a reinforcement hole into which the molding extends to enhance 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 a shielding layer, which is wrapped outside or around the integrated base 11 to enhance the anti-electromagnetic interference capability 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 unitary base 11 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 distance, 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, that is, 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 by different lines, but are not limited to materials or structures.

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, so that the mounting position of the filter element 50 is not sunk in the optical window 111 as compared with the above embodiment, but the required area of the filter element 50 can also be reduced by the extending distance of the inward extending arm 44B, and the filter element 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 lens mount 40B1 includes a filter lens mount main body 43B1 and at least one inward extending arm 44B1, and the inward extending arm 44B1 transversely and integrally extends inward from a lower portion of the filter lens mount 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 with the lens 30 to facilitate mounting and adjustment of the lens 30.

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 lens mount 40B2 includes a filter lens mount main body 43B2 and at least one inward extending arm 44B2, and the inward extending arm 44B2 transversely and integrally extends inward from a lower portion of the filter lens mount 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. 9 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 441C, and the corner 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 the edge shadow caused by a sharp corner in the imaging of the camera module. More specifically, two adjacent inwardly extending arms 44C form a corner 441C, and the corner 441C extends outwardly so as to increase the light flux of the camera module at the corner position of the filter element holder 40. In other words, the corner 441C extends outward and is formed adjacent to the inwardly extending arm 44C, so as to increase the luminous flux of the filter element mount 40 at the corner 441C and reduce the edge shadow.

Specifically, in one embodiment, the corners 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 stage 40. In other embodiments, the corner 441C may be a circular arc angle to increase the light flux at the corner of the filter element mount 40. Of course, in some embodiments, the corner 441C may not be provided, and those skilled in the art should understand that the shape, number and position of the corner 441C are not limitations of the present invention.

As shown in fig. 56, is a modified embodiment according to the first preferred embodiment of 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 a light path for the light sensing element 13. 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 element lens holder 40 body is coupled to the U-shaped structure of the base body 112D, and the extension leg 433D of the filter element lens holder 40D complements an opening 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 on the circuit board 12, the arrangement position of the electrical connection element 133, the packaging position of the integrated base 11, and the like need to be reasonably arranged, so that the occupied area of the element layout is the minimum while the substrate 121 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 122 is integrally packaged in the direction in which the electronic component 122 is arranged, the electronic component 122 is encapsulated, the electromagnetic influence between the electronic component 122 and the electrical connection element 133 is reduced while utilizing the spatial position of the electronic component 122, and 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 noted that the substrate 121 needs to be provided with the photosensitive element 13, the electronic component 122, the electrical connection element 133, the integrated base 11D, and the filter element lens holder 40D, and the electronic component 122, the electrical connection element 133, the integrated base 11D, and the filter element lens holder 40D are disposed around the photosensitive element 13. In other words, the substrate 121 has a plurality of mounting regions 1213, the mounting regions 1213 surrounding the photosensitive elements 13. 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 further covered by the integral base 11D, and the filter element mount 40D is connected to the mounting area 1213 on which the electronic components 122 and/or the electrical connection element 133 are not disposed, so that the filter element mount 40D and the integral base 11D form the optical window 111D by matching with each other through the filter element mount 40D at a narrower position on the substrate 121, thereby providing a light path for the photosensitive element 13. That is, the photosensitive element 13 is not disposed at the center of the substrate 121, but is biased to one side, forming 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 mount 40D is connected to a narrow position where the electronic component 122 and the electrical connection element 133 are not disposed, and the wider mounting region 1213 mounts the electronic component 122 and the electrical connection element 133, 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 to the wider W2 side, so that the electronic component 122 is intensively provided to 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 13 to the substrate 121, mount the mounting regions 1213 with different widths at the mounting positions where the photosensitive element 13 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 photosensitive element 13 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 on the substrate 121 can be more reasonably utilized.

As shown in fig. 12A to 13, 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 111F for providing a light path for the light sensing element 13. Further, the integrated base 11E has two openings 1121F, each of the openings 1121F communicates with the optical window 111F and the outside, and the filter element lens holder 40E supplements the two openings 1121F to close the side surface of the optical window 111F.

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 1121F. By way of example and not limitation, each of the extension legs 433E is attached to the base plate 121 and/or the base body 112 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. 58 and 59 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 light sensing element 13. 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 face 4331Q and the open face 1122Q of the base body 112Q may be secured or sealed by glue bonding therebetween.

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. Preferably, when the filter lens holder 40 is mounted in the mounting groove 115F, the top surface of the filter lens holder 40 is identical to the top surface of the base body 112F, so that the filter lens holder 40 does not protrude from the base body 112F and the driver 60 or the lens 30 located above is not easily touched. Of course, in other embodiments of the present invention, the upper surface of the filter element lens holder 40 may protrude from the base body 112F, so as to fit different sizes of the driver 60, limit the driver 60, and prevent the glue from overflowing to the inside when the driver is installed, which is not limited in this respect.

More specifically, the integrated base 11F includes a plurality of raised steps 116F protruding from the base body 112F. The raised step 116F extends upward from the base body 112F partially to form the mounting groove 115F.

In other embodiments of the present invention, the width of the raised step 116F can be changed as required, and accordingly, the width of the main body of the filter element lens holder 40 can be designed according to the width of the mounting groove 115F.

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

According to this embodiment of the present invention, the integrated base 11G includes three raised steps 116G, and the raised steps 116G are turnably integrally connected to form the mounting grooves 115G. That is, the side without the raised step 116G forms the notch 117G. More specifically, three of the raised steps 116G are rotationally integrally connected to form a U-shaped raised structure.

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

It should be noted that the electronic components 122 are disposed at different positions of the main body of the circuit board 12, and the integrated base 11G covers the electronic components 122. In the position of arranging electronic component 122, the thickness that integrative base 11G needs is great, and conveniently sets up mounting groove 115G, and does not have electronic component 122's position can set up less thickness, thereby it is right to reduce circuit board 12 size, is unsuitable to set up mounting groove 115G.

In some embodiments, there is a gap between the driver 60 and the extended edge 432G, and the gap is sealed with glue to form a closed internal environment for the camera module. In other words, the extended edge 432G has a surface height lower than that of the raised step 116G, and the height difference can be supplemented by glue. Specifically, the actuator 60 may be mounted to the protruding step 116G by bonding, and make the optical axes of the lens 30 and the photosensitive element 13 coincide.

As shown in fig. 16A and 16B, is a camera module according to a fifth preferred embodiment of the present invention. The integrated base 11H has at least one mounting groove 115H, and the mounting groove 115H is communicated with the optical window 111H. The filter element mount 40H is mounted to the mounting groove 115H. More specifically, each of the mounting grooves 115H forms a U-shaped structure, and the U-shape has no opening.

Specifically, the engagement groove 42H of the filter element mirror holder 40H is engaged with the attachment groove 115H of the integrated base 11H, so that the filter element mirror holder main body 43HH of the filter element mirror holder 40HH is supported in the support groove 41H.

Further, the filter lens mount 40HH has a U-shaped structure with an opening, and the U-shaped structure of the filter lens mount 40HH matches the shape formed by each of the mounting grooves 115H.

The filter base main body 43HH of the filter base 40HH has a predetermined thickness so that it is not easily touched to the components located above, such as the driver 60 or the lens 30.

The inner extension arm 44HH is formed to extend laterally and integrally with the extension bus arm in a direction of rotation to form a supporting groove 41H for providing a mounting position for the filter element 50. And unlike the above-described embodiment, the engagement groove 42HH and the support groove 41H are both of a U-shaped structure having an opening on one side, and are not of a closed structure. That is, when the filter element 50 is mounted on the filter element base 40HH, only three sides are fixed, and one side directly abuts against the protruding step 116HH where the mounting groove 115H is not formed.

It is worth mentioning that the electronic components 122 are arranged at different positions of the main body of the circuit board 12, and the integrated base 11H covers the electronic components 122. Arranging electronic components 122's position, the thickness that integrative base 11H needs is great, and conveniently sets up mounting groove 115H, and does not have electronic components 122H's position can set up less thickness to reduce circuit board 12 size, unsuitable setting mounting groove 115H.

Unlike the preferred embodiment, the integrated base 11I includes two raised steps 116I and two notches 117I, and the raised steps 116I are integrally connected in a turned manner to form the mounting groove 115I. That is, the notch 117I is formed on both sides without the raised step 116I.

Unlike the preferred embodiment described above, the integral base 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, when the camera module is assembled, the driver 60 or the lens 30 is installed in the position-limiting opening 461L of the filter element mount 40, and the driver 60 or the lens 30 is limited, so that the optical axis of the driver 60 or the lens 30 is consistent with the optical axis of the photosensitive element 13. 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 40, 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 shelter from outside dust and get into inside the module of making a video recording.

The under-wrap port 471M is used for accommodating the integrated base 11, that is, when the camera module 100 is assembled, the driver 60 or the lens 30 is installed in the limiting port 461M of the filter element lens holder 40M, the integrated base 11 is accommodated in the under-wrap port 471M, the upper extension wall 46M limits and shields the lens 30, so that the optical axes of the lens 30 and the photosensitive element 13 are consistent, and the lower extension wall 47M shields the integrated base 11, so that the camera module 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 11.

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 12 by gluing, so that the filter element holder 40 is more stably mounted.

In the figure, the camera module 100 is applied to a smart phone to assist the smart phone in acquiring and reproducing image information.

Fig. 25A to 27 show an array camera module according to an eleventh preferred embodiment of the present invention. The array camera module 1000 comprises a plurality of camera module units 100, and the camera module units 100 are matched with each other to realize image acquisition. The array camera module 1000 may be applied to various electronic devices 300, for example, but not limited to, smart phones, wearable devices, computer devices, televisions, vehicles, cameras, monitoring devices, and the like, and the array camera module 1000 is used with the electronic devices 300 to capture and reproduce images of a target object.

It should be noted that, for convenience of description, in the following embodiments and the accompanying drawings of the present invention, the array camera module 1000 formed by two camera module units 100, i.e. a dual-camera array camera module, is taken as an example for description, but in other embodiments of the present invention, the array camera module 1000 may include more units, e.g. three or more, and each camera module unit 100 is arranged in an array to form the array camera module 1000, e.g. arranged in parallel.

It should be noted that the image capturing module 100, the image capturing module formed by combining the features of the image capturing module 100, and the image capturing module implemented equivalently in the first to tenth preferred embodiments can be used as the image capturing module unit 100 to form the array image capturing module 1000.

Specifically, the camera module unit 100 includes an integrated base assembly 10, the photosensitive element 13, the lens 30, and a filter element holder 40.

The photosensitive element 13 is electrically connected to 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 13.

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 being integrally packaged on the circuit board 12 by molding, and the filter element lens base 40 is mounted on the integrated base 11, so that the integrated base 11 and the filter element 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 13 is operatively connected to the circuit board 12.

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 light sensing element 13, and the base main body 112 is integrally encapsulated in the circuit board 12 by molding. In particular, the light window 111 is a closed ring 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 further contaminating the photosensitive element 13, which affects the imaging effect, like 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, or the like. 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.

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 13 includes a front surface 131 and a back surface 132, the front surface 131 is opposite to the lens 30 for performing a photosensitive function, and the back surface 132 is opposite to the lens 30 for being mounted on the upper surface 1211 of the substrate 121. The photosensitive element 13 is electrically connected to the substrate 121 through at least one electrical connecting element 133. The electrical connection element 133 is exemplified by, but not limited to, a gold wire, a silver wire, a copper wire, an aluminum wire. The photo sensor is mounted on the substrate 121 by, but not limited to, a Surface Mount Technology (SMT) process, and is electrically connected to the substrate 121 by a COB (Chip 0n Board) gold bonding process. Of course, in other embodiments of the present invention, the photosensitive element 13 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 13 and the circuit board 12 is not limited by the present invention.

More specifically, the front surface 131 of the photosensitive element 13 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 133 to transmit the electrical signal to the circuit board 12. The lens 30 and the photosensitive element 13 are arranged in optical alignment, and the optical axes are the same, so that the light passing through the lens 30 can reach the photosensitive element 13 through the optical window 111, and further after photoelectric conversion of the photosensitive element 13, an electrical signal can be transmitted to the circuit board 12, so that the image information can be acquired by the camera module.

As shown in fig. 25A and 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 13. 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 light 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 13 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, the distance from the light sensing element 13 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 13, 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 13 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 between 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 with different widths, and accordingly, the filter element lens holder main body 43 may be provided with a corresponding groove or protruding position, or the lengths of the inward extending arms 44 are different to adapt to the shape of the integrated base 11, to adapt to the position of the photosensitive element 13, and to facilitate installation of the filter element 50.

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.

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 13 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 d1, 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, thereby making the installation of the filter element mirror holder 40A more stable.

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 slot 41B, and the supporting slot 41B is communicated with the corresponding optical window 111 of the integrated base 11 to provide an installation position for the filter element 50.

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 engagement slot 42, and thus the mounting position of the filter element 50 is not sunk in the optical window 111, 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 inner extending arm 44B1, and the inner extending arm 44B1 transversely and integrally extends inward from a lower portion of the filter element mirror base 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.

That is, when the camera module unit 100 is a fixed-focus camera module, the lens 30 can be directly mounted inside the filter lens holder 40B1, so as to limit 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.

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 inner extending arm 44B2, and the inner extending arm 44B2 transversely and integrally extends inward from a lower portion of the filter element mirror base 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.

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

In this embodiment, each of the filter element lens holders 40 has at least one corner 441C, and the corner 441C is disposed at a corner position of the filter element lens 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 441C, and the corner 441C extends outwardly so as to increase the light flux of the camera module at the corner position of the filter element holder 40.

Specifically, in one embodiment, the corners 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 stage 40. In other embodiments, the corner 441C may also be rounded to increase the light flux at the corner of the filter mount 40. Of course, in some embodiments, the corners 441C may not be provided, and those skilled in the art will understand that the shape, position and number of the corners 441C are not a limitation of the present invention.

In this embodiment of the present invention, each of the filter element mounts 40 includes a retention projection 46P, and the retention projection 46P extends at least partially, convexly upward from the top of the filter element 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 this embodiment of the present invention, the integral filter element mount 1400 includes two of the limiting protrusions 46P, each forming an annular protrusion for limiting the corresponding actuator 60. In another embodiment, the bridge 1410, which is the middle portion of the connected filter element lens base 1400 formed by the two filter element lens bases 40, may not be provided with the limiting protrusion 46P, and only the limiting protrusion 46P may be provided around the connected filter element lens base 1400.

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

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 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 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.

In other words, in this embodiment, the integral base 11D and the filter element mount 40D collectively assume the function of the lens mount of the camera module, so that the advantages of the integral package 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 on the circuit board 12, the arrangement position of the electrical connection component 133, 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 smallest while the substrate 121 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 122 is integrally packaged in the direction in which the electronic component 122 is arranged, the electronic component 122 is covered, the electromagnetic influence between the electrical component and the electrical connection element 133 is reduced while utilizing the spatial position of the electronic component, and the filter element holder 40D is provided in a manner in which the electrical 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 37 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 13. 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 1121F to close the side surface of the optical window 111F.

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 121F so as to close each of the openings. By way of example and not limitation, each of the extension legs 433E is attached to the base plate 121 and/or the base body 112 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 111F, and isolates the light paths of the two camera modules. That is, in this embodiment, the 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 111F, and the other two extension legs 4333E respectively supplement the openings 1121E of the base 1110, thereby forming two closed and independent optical windows 111E. In other words, in the array camera module 1000, the two optical windows 111F of the two camera module units 100 are communicated with each other, and the conjoined base 1110 is supplemented by the conjoined filter element lens seat 1400 to form two separated and closed optical windows 111F. And the adjacent extension legs 433E of the filter element mount 40E form a common portion instead of the conjoined portion 1111 of the conjoined base 1110. In one embodiment, two adjacent extension legs 433E are integrally connected.

Unlike the above embodiments, in the integrated base assembly 1100, 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 1400 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, and are adapted to supplement the corresponding openings 1121Q. For example, when the filter element mount 40Q is mounted, the extending leg is limited to the opening 1121Q, and respectively closes the two optical windows 111F.

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 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 two bases, i.e., the connection portion 1111 of the one-piece base 1110, and is connected to both sides. That is, the gap 117F communicates with the two mounting grooves 115, so as to accommodate the bridging portion 1410 of the conjoined filter element lens holder 1400.

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 holders 40F are butted to form a 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 1410.

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 components 122 are arranged at different positions of the main body of the circuit board 12, and the integrated base 11F covers the electronic components 122. At the position where the electronic component is arranged, the thickness required for the integrated base 11F is large, and the installation groove 115F is conveniently provided, but the position without the electronic component 122 can be provided with a small thickness, so that the size of the circuit board 12 is reduced, and the installation groove 115F is not suitable to be provided. According to this embodiment of the present invention, the electronic component 122 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 13 coincide.

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

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.

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 11, that is, when the array camera module 1000 is assembled, the driver 60 or the lens 30 is installed in the limiting port 461M of the filter element lens holder 40M, the integrated base 11 is accommodated in the under-wrap port 471M, the upper extension wall 46M limits and shields the lens 30, so that the optical axes of the lens 30 and the photosensitive element 13 are consistent, and the lower extension wall 47M shields the integrated base 11, so that the array camera module 1000 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 11.

In one embodiment, the lower wall 47M may extend to the circuit board 12, for example, but not limited to, by being fixedly connected to the circuit board 12 by gluing, so that the filter element holder 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 40. The lens wall 118N and the raised step 116N form another mounting slot 115N for providing a mounting location for the lens 30.
