Background
With the popularization of mobile electronic devices, technologies related to camera modules applied to mobile electronic devices for helping users to obtain images (such as videos or images) have been rapidly developed and advanced. Particularly, with the development of smart phones, the pursuits of consumers for shooting functions are more and more diversified, the requirements for imaging quality are higher and higher, effects such as background blurring and night shooting are required to be achieved, and the demand for telephoto shooting is also provided.
To achieve the telephoto function, the mobile electronic device starts to introduce a camera module with a telephoto lens, and in order to avoid the development trend that the longer optical total length of the telephoto lens makes the size of the camera module too large to be compatible with the miniaturization of the electronic device, a prism or a mirror is usually adopted to fold the optical path of the camera module, so that the camera module can be transversely placed in the electronic device, and the camera module is called a "periscopic camera module".
For promoting the performance of periscopic camera module, periscopic camera module still includes the motor that is used for moving optical lens to realize functions such as optics anti-shake, auto focus or optics zoom. In the existing periscopic camera module, for example, in the periscopic camera module disclosed in chinese patents CN201920034728.4 and CN201910770361.7, the periscopic camera module includes a U-shaped carrier for carrying an optical lens, the optical lens is mounted in the U-shaped carrier, and a motor drives the U-shaped carrier to move to implement the above-mentioned optical adjustment function.
In the assembling process, the optical lens is installed into the U-shaped carrier from the direction of light rays entering the periscopic camera module, and the lens is fixed in the U-shaped carrier through a large amount of glue. However, the arrangement of the glue greatly affects the performance of the optical lens and the stability of the position of the lens in the periscopic camera module, which results in the serious degradation of the imaging quality of the periscopic camera module.
Therefore, an optimized periscopic camera module structure design scheme and an optimized packaging scheme are needed.

Detailed Description
Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein.
Summary of the application
As mentioned above, in the existing periscopic camera module, for example, in the periscopic camera modules disclosed in chinese patents CN201920034728.4 and CN201910770361.7, the periscopic camera module includes a U-shaped carrier for carrying an optical lens, the optical lens is mounted in the U-shaped carrier, and the motor drives the U-shaped carrier to move to implement the above-mentioned optical adjustment function.
In the assembling process, the optical lens is installed into the U-shaped carrier from the direction of light incidence periscopic camera module, and the lens is fixed in the U-shaped carrier through a large amount of glue. However, the arrangement of the glue greatly affects the performance of the optical lens and the stability of the position of the lens in the periscopic camera module, which results in the serious degradation of the imaging quality of the periscopic camera module.
Through research, the inventor of the present application finds that, in the process of curing the glue, the glue shrinks to generate tensile stress on the optical lens, so that a certain stress is generated inside the lens, and the stress can cause surface deformation or position deviation of the optical lens located inside the optical lens, so that the resolving power of the optical lens is reduced.
In addition, in the process of baking, curing and cooling the periscopic camera module, the glue arranged between the lens barrel of the optical lens and the U-shaped carrier can cause different shrinkage of the lens barrel and the glue due to different thermal expansion coefficients of the glue and the lens barrel, so that the relative position relationship between the optical lens and the U-shaped carrier is deviated. Moreover, a certain stress is generated inside the lens, which affects the surface shape of the optical lens in the optical lens, and reduces the imaging quality of the periscopic camera module.
In some existing periscopic camera modules, in order to reduce the overall height dimension of the periscopic camera module, a D-CUT optical lens is adopted, the D-CUT lens does not have an approximately circularly symmetric shape like the optical lens in a conventional module, and the D-CUT lens or the D-CUT lens has different sizes in two perpendicular radial dimensions, so that the D-CUT lens or the D-CUT lens is affected by more uneven stress, and particularly, the face shape change is more serious due to the stress in the direction of the shorter radial dimension of the D-CUT lens.
In view of the above technical problems, the present application is based on the idea of positioning and limiting the relative position of an optical lens with respect to a lens carrier by other limiting mechanisms to reduce (even eliminate) the amount of adhesive applied to fix the optical lens to the lens carrier, thereby reducing (even avoiding) the relative position of the optical lens with respect to the lens carrier and/or the deformation of the optical lens inside the optical lens due to curing shrinkage of the adhesive.
Based on this, this application provides a periscopic module of making a video recording, and it includes: an outer housing; the light turning module is positioned in the outer shell and comprises a light turning unit for turning the imaging light; be located in the shell and corresponding to the camera lens module of light turn module, the camera lens module be equipped with along the length direction's of periscopic camera module group optical axis, wherein, the camera lens module includes: the optical lens comprises an optical lens, a lens carrier and a limiting device, wherein the lens carrier is provided with a mounting cavity and an opening formed in the top area of the lens carrier, and the opening is communicated with the mounting cavity so that the optical lens is suitable to be mounted into the mounting cavity from the top of the lens carrier through the opening; the limiting device comprises a first limiting mechanism and a second limiting mechanism, wherein the first limiting mechanism is arranged between the lens carrier and the optical lens and used for limiting the optical lens to move along the optical axis; the second limiting mechanism is arranged on the lens carrier, and the inner surface of the second limiting mechanism is suitable for abutting against the upper surface of the optical lens and is used for limiting the optical lens to move towards the opening, so that the optical lens is kept in the installation cavity; and a photosensitive module corresponding to the lens module, wherein the photosensitive module includes a photosensitive unit for imaging.

As shown in fig. 1, the package housing 12 further has an opening formed through the cover plate 13, and the opening forms an optical window 101 corresponding to the light turning module 20, for allowing external imaging light to enter the outer housing 10 through the optical window 101.
It should be noted that, in the embodiment of the present application, the base plate 11 may have an integrated structure, which simultaneously carries the lens module 30 and the light turning module 20 thereon. Of course, in other examples of the present application, the base plate 11 may have a split structure, for example, it includes a first base plate and a second base plate separated from each other, where the first base plate carries the lens module 30, and the second base plate carries the light turning module 20, which is not limited in this application.

That is, in the embodiment of the present application, the lens carrier 32 has an opening 321 facing a direction in which light is incident on the optical window 101, and the position of the opening 321 is set so that the optical lens 31 can be mounted in the mounting cavity 320 of the lens carrier 32 from above the lens carrier 32. That is, in the embodiment of the present application, the posture of the optical lens 31 may be adjusted from above the lens carrier 32 so that the relative positional relationship between the optical lens 31 and the lens carrier 32 satisfies a preset requirement.

It should be understood that, in the embodiment of the present application, when the optical lens 31 is installed in the installation cavity 320 from the opening 321, at least one protrusion 335 protrudingly formed on the inner surface of the lens carrier 32 is engaged with at least one groove 336 concavely formed on the outer surface of the optical lens 31, so as to pre-position the optical lens 31 in the installation cavity 320 and limit the optical lens 31 from moving along the optical axis.
As shown in fig. 4 to 6 and fig. 8, in the embodiment of the present application, the at least one protrusion 335 is circumferentially formed on the inner surface of the lens carrier 32, and the at least one groove 336 is circumferentially formed on the outer surface of the optical lens 31, so that when the optical lens 31 is installed in the installation cavity 320 from the opening 321, the degree of freedom of the optical lens 31 relative to the lens carrier 32 in the X, Y direction is restricted by the first limiting mechanism 331.
Preferably, in the embodiment of the present application, the at least one protrusion 335 has a curved strip shape, and the at least one groove 336 has a curved strip shape, so as to increase the contact area between the at least one protrusion 335 and the at least one groove 336, and the curved strip-shaped matching medium can more effectively prevent the optical lens 31 from moving along the optical axis direction.
It should be noted that, in the embodiment of the present application, the number of the at least one protrusion 335 and the at least one groove 336 is not limited in the present application, and several of the at least one protrusion 335 and the at least one groove 336 may be appropriately disposed to enhance the limiting effect, which is not limited in the present application.
In an embodiment, marks (for example, as shown in fig. 4 to 6 as L marks) may be made on the lens carrier 32 and the optical lens 31, so as to identify and judge the relative posture between the optical lens 31 and the lens carrier 32 according to the states of the marks, and further, by identifying the direction of the marks, the optical lens 31 may be installed in the installation cavity 320 of the lens carrier 32 from the opening 321 in a correct direction, and the at least one protrusion 335 is engaged with the at least one groove 336 in a matching manner.
Of course, in other examples of the present application, the relative position relationship between the at least one protrusion 335 and the at least one groove 336 may be adjusted, for example, the at least one protrusion 335 is formed protrudingly on the outer surface of the optical lens 31, and the at least one groove 336 is formed concavely on the inner surface of the lens carrier 32, that is, the first limiting mechanism 331 includes at least one groove 336 formed concavely on the inner surface of the lens carrier 32 and at least one protrusion 335 formed protrudingly on the outer surface of the optical lens 31, which is not limited in this application.
In order to further limit the movement of the optical lens 31 in the X and Y directions, in the embodiment of the present application, as shown in fig. 9A, the position limiting device 33 further includes an adhesive 334 disposed between the lens carrier 32 and the optical lens 31. That is, in the embodiment of the present application, the optical lens 31 is pre-fixed in the lens carrier 32 by the first position-limiting mechanism 331 and the adhesive 334, wherein the adhesive 334 is disposed between the first retaining arm 323 and the optical lens 31 and/or between the second retaining arm 324 and the optical lens 31 and/or between the optical lens 31 and the carrier base 322.
In the embodiment of the present application, the adhesive 334 with a lower elastic modulus is used to prevent the adhesive 334 from having a large influence on the optical lens 31. More specifically, in the embodiment of the present application, the elastic modulus of the adhesive 334 is equal to or less than 1.2Gpa, and preferably, the elastic modulus of the adhesive 334 is equal to or less than 0.6Gpa. In the present embodiment, the elastic modulus of the adhesive 334 means the elastic modulus of the adhesive 334 after curing.
In particular, when the optical lens 310 in the optical lens 31 is implemented as a side cut lens, the application position of the adhesive 334 is preferably that the adhesive 334 is disposed between the first retaining arm 323 and the optical lens 31 and/or between the second retaining arm 324 and the optical lens 31 because when the lens is a side cut lens, the lens barrel is more adjacent to the optical area of the optical lens 310 in the optical lens 31 on the side of the side cut thereof, whereas in the present embodiment, the side cut of the optical lens 31 corresponds to the carrier base 322, so that if the adhesive 334 is applied between the optical lens 31 and the carrier base 322, the adhesive 334 has a greater influence on the side cut of the side cut lens.
It should be noted that, in the embodiment of the present application, the edge-cutting lens includes the lens barrel and at least one edge-cutting optical lens 310 accommodated in the lens barrel, wherein the edge-cutting optical lens 310 has at least one edge. In the embodiment of the present application, the number of the cut edges is preferably 2 or 4. The edge-cut optical lens 310 may be formed by grinding or cutting the lens after the optical lens 310 is molded, or may be directly shaped by the shape of the mold when the lens is molded. The barrel also has at least one cut edge corresponding to the cut edge of the cut edge optical lens 310.
As one of ordinary skill in the art will appreciate, the optical lens 310 on the image side in the optical lens 31 has a low sensitivity, and here, the low sensitivity of the optical lens 310 means that the influence of moving the position of the optical lens 310 or changing the shape of the optical lens 310 on the resolution of the optical lens 31 is relatively low compared to other optical lenses 310. That is, the optical lens 310 of the optical lens 31 near the light exit side 312 of the optical lens 31 has a lower optical lens 310 sensitivity, while the optical lens 310 of the optical lens 31 near the light entrance side 311 of the optical lens 31 has a higher optical lens 310 sensitivity. Therefore, preferably, in the embodiment of the present application, the adhesive 334 is disposed at a position close to the light-emitting side 312 of the optical lens 31, that is, preferably, the adhesive 334 is disposed at a second portion of the lens carrier 32 close to the light-emitting side 312 of the optical lens 31.
It is worth mentioning that in other examples of the present application, the first position-limiting mechanism 331 alone may be used to pre-position the optical lens 31 without using the adhesive 334; alternatively, in other examples of the present application, the adhesive 334 may be used alone to pre-position the optical lens 31, that is, in this example, the first limiting mechanism 331 may be implemented as the adhesive 334.
It should be understood that after the optical lens 31 is limited by the first limiting mechanism 331, the optical lens 31 is limited in movement in the X, Y direction, but can be moved in the Z direction, i.e., toward the opening 321 of the lens carrier 32. Accordingly, the second limiting mechanism 332 is used for limiting the movement of the optical lens 31 toward the opening 321, i.e., limiting the degree of freedom of the optical lens 31 in the Z direction.
As shown in fig. 4 to 6, and fig. 8 and 9A, the second limiting mechanism 332 includes a blocking plate 337 adapted to be engaged with the lens carrier 32, and when the blocking plate 337 is engaged with the lens carrier 32, a lower surface of the blocking plate 337 abuts against an upper surface of the optical lens 31, so as to limit the optical lens 31 from moving toward the opening 321.
Specifically, in the embodiment of the present application, the barrier 337 includes a barrier main body 3371 and first and second engaging arms 3372 and 3373 extending downward from both sides of the barrier main body 3371, respectively, wherein the lens carrier 32 includes a first engaging groove 3231 concavely formed on an upper surface of the first holding arm 323 and a second engaging groove 3241 concavely formed on an upper surface of the second holding arm 324, and wherein the first and second engaging arms 3372 and 3373 of the barrier 337 are adapted to be engaged with the first and second engaging grooves 3231 and 3241, respectively, in such a manner that the barrier 337 is engaged with the lens carrier 32. When the baffle 337 is engaged with the lens carrier 32, the lower surface of the baffle 337 contacts the upper surface of the optical lens 31 to provide a contact force for preventing the optical lens 31 from falling off from the opening 321. That is, in the embodiment of the present application, when the baffle 337 is engaged with the lens carrier 32, there is contact (for example, point contact, line contact, or surface contact, preferably surface contact) between the baffle 337 and the optical lens 31 carrier to restrict the optical lens 31 from moving toward the opening 321 by the baffle 337.
As will be appreciated by those skilled in the art, in the periscopic camera module, in order to increase the light-entering amount of the periscopic camera module and increase the aperture of the periscopic camera module, the optical lens 310 of the optical lens 31 near the object side has a larger size, and the optical lens 310 thereof near the image side has a relatively smaller size, that is, in the applied embodiment, the first portion of the lens carrier 32 has a relatively larger size, and the second portion of the lens carrier 32 has a relatively smaller size. Preferably, in the embodiment of the present application, the baffle 337 is engaged with a second portion of the lens carrier 32 close to the light incident side 311 of the optical lens 31, so that a larger contact area can be provided between the upper surface of the optical lens 31 and the lower surface of the baffle 337, so as to improve the position limiting effect.
Moreover, since the first position-limiting mechanism 331 is disposed at the first portion of the lens carrier 32 close to the light-emitting side 312 of the optical lens 31, a pair of balanced position-limiting forces is formed by the position-limiting forces provided by the first position-limiting mechanism 331 and the baffle 337 to a certain extent, so as to achieve better positioning and position-limiting effects.
In order to make the baffle 337 more firmly limit the optical lens 31, the baffle 337 has to have sufficient strength. In a specific implementation, when the baffle 337 is made of a plastic material (e.g., injection molded from a plastic material such as polycarbonate), the thickness of the baffle 337 is greater than or equal to 0.4mm, for example, the thickness of the baffle 337 may be set to 0.5mm. Of course, the thicker baffle 337 may affect the height dimension of the periscopic camera module, and therefore, in the embodiment of the present application, preferably, the baffle 337 is made of a metal material (e.g., steel, iron, copper, aluminum, etc.), and the thickness of the baffle 337 may range from 0.1mm to 0.2mm, for example, the thickness of the baffle 337 made of a metal material may be set to 0.15mm, which may ensure that the optical lens 31 does not fall off, and may also avoid the height of the periscopic camera module being too large.
In order to prevent the blocking plate 337 from falling off the lens carrier 32, in the embodiment of the present invention, as shown in fig. 9A, an adhesive 334 may be applied in the first engaging groove 3231 and the second engaging groove 3241 to firmly fix the blocking plate 337 on the upper surface of the lens carrier 32.
Of course, in other examples of the present application, the bezel 337 and the lens carrier 32 may be fixed by a mechanical structure without passing through the adhesive 334, so as to avoid the position shift of the bezel 337 caused by the curing shrinkage or baking curing variation of the adhesive 334. Specifically, as shown in fig. 9B to 9C, the lens carrier 32 further has female fasteners respectively disposed in the first engaging groove 3231 and the second engaging groove 3241, and the first engaging arm 3372 and the second engaging arm 3373 of the blocking plate 337 respectively include male fasteners formed at end portions thereof, so that the blocking plate 337 is stably fixed to the lens carrier 32 by engagement between the male fasteners and the female fasteners.
Of course, in other examples of the present application, the mechanical structure (i.e., a male buckle and a female buckle as illustrated in fig. 9B and 9C, for example) may also be used in cooperation with the adhesive 334, that is, the adhesive 334 may be further applied in the first and second engaging grooves 3231 and 3241, as shown in fig. 9D, so as to more stably ensure the relative positional relationship between the bezel 337 and the lens carrier 32 by the mechanical structure and the adhesive 334.
Of course, in other examples of the present application, the position of the female buckle of the mechanical structure may not be in the first and second engaging grooves 3231 and 3241 of the lens carrier 32, for example, as shown in fig. 9E and 9F, and the position of the female buckle is provided on the outer and inner side walls of the first and second holding arms 323 and 324 of the lens carrier 32, which is not limited by the present application.
Fig. 9G illustrates a schematic diagram of yet another variant implementation of the lens module 30 according to an embodiment of the present application. As shown in fig. 9G, in this modified embodiment, the second limiting mechanism 332 further includes a buffer layer 338 overlapping the lower surface of the blocking plate 337, wherein the buffer layer 338 is used to suitably reduce the interference force of the blocking plate 337 on the optical lens 31, and reducing the pressure of the blocking plate 337 on the optical lens 31 is beneficial to reduce the deformation degree of the optical lens 310 in the optical lens 31; meanwhile, the baffle 337 can also appropriately reduce the impact of the optical lens 31 on the baffle 337.
That is, in this modified embodiment, the buffer layer 338 is also provided between the upper surface of the optical lens 31 and the lower surface of the barrier 337. In a specific implementation, the buffer layer 338 may be integrally formed on the lower surface of the baffle 337, or may be provided separately from the baffle 337, which is not limited in this application. In terms of material selection, the buffer layer 338 can be made of foam or the like.
Fig. 9H illustrates a schematic diagram of a further variant implementation of the lens module 30 according to an embodiment of the present application. As shown in fig. 9H, in this modified embodiment, the position-limiting device 33 further includes a third position-limiting mechanism 333 disposed between the baffle 337 and the upper surface of the optical lens 31, and the third position-limiting mechanism 333 includes at least one position-limiting hole 3331 concavely formed on the lower surface of the baffle 337 and at least one position-limiting post 3332 convexly formed on the upper surface of the optical lens 31, wherein when the baffle 337 is locked to the lens carrier 32, the at least one position-limiting hole 3331 is engaged with the at least one position-limiting post 3332.
In this way, when the baffle 337 is fixed to the lens carrier 32, the at least one position-limiting post 3332 disposed on the upper surface of the optical lens 31 passes through the at least one position-limiting hole 3331 of the baffle 337, so that the position of the optical lens 31 relative to the baffle 337 is not easily moved after the baffle 337 is mounted, and further, the reliability of the lens module 30 in the periscopic camera module is improved.
Preferably, the number of the at least one limiting hole 3331 and the at least one limiting post 3332 is preferably at least two.
In summary, it is clarified that the periscopic camera module and the lens module 30 thereof according to the embodiment of the present application locate and limit the relative position of the optical lens 31 with respect to the lens carrier 32 by other limiting mechanisms to reduce (even eliminate) the amount of the adhesive 334 applied for fixing the optical lens 31 to the lens carrier 32, so as to reduce (even avoid) the relative position of the optical lens 31 with respect to the lens carrier 32 from shifting and/or the optical lens 31 inside the optical lens 31 from deforming due to the curing and shrinking of the adhesive 334.
It should be noted that, in the embodiment of the present application, the periscopic camera module further includes a driving element (not shown in the figure) for driving the lens module 30 and/or the light turning module 20. For example, in the embodiment of the present application, the light turning module 20 may further include a first driving element for moving the light turning element 21 carrier to drive the light turning element 21, for example, the first driving element is used for rotating the light turning element 21 carrier to rotate the light turning element 21 to achieve the purpose of optical anti-shake.
