Abstract
Description
Technical Field
[0001] The present application relates to the field of camera modules, and more specifically to a housing, a camera module, an assembly method and an electronic device. Background Art
[0002] Camera modules are an indispensable part of mobile electronic devices. With the further development of camera module technology, users' demands for camera modules have become more and more refined and have higher requirements. The development of camera products not only needs to meet the requirements of high performance, but also needs to meet the requirements of miniaturization, lightness, and compactness. The internal space of electronic devices such as mobile phones and tablets is becoming more and more compact, and the space for accommodating camera modules is very limited, so higher and higher requirements are placed on the size of camera modules.
[0003] The camera module usually includes a lens and a photosensitive component. The incident light beam passes through the lens to the photosensitive component and forms an image in the photosensitive component. The lens and the photosensitive component are usually assembled to the base to form a part of the camera module. The periscope camera module or telephoto camera module also includes a prism, which can bend the direction of the light beam at least once, which is used to fold the light path and achieve telephoto shooting.
[0004] The camera module also includes a housing and a bracket. The housing is mounted on the outside of the base or above the base of the photosensitive component to cover at least part of the internal structure of the base. The bracket is further mounted on the outside of the housing. Generally speaking, the housing covers the internal structure of the camera module. The bracket is assembled to the outside of the housing and is suitable for fixing to the electronic device. The bracket usually has a positioning hole, which is aligned with the corresponding positioning hole on the electronic device and then screwed to fix it, so that the camera module is assembled to the electronic device.
[0005] When assembling the camera module, it is necessary to first assemble the outer shell to the base of the camera module, and then assemble the bracket to the outside of the outer shell. There are many assembly steps and calibration steps, and there are many assembly gaps between multiple components, which easily cause interference or tolerance accumulation.
[0006] Furthermore, since the bracket and the housing are two independent parts, when the bracket is assembled to the outer periphery of the housing, glue needs to be set between the bracket and the housing for curing. At the same time, the optical lens and motor assembly are further assembled inside the housing, which are also often cured with glue. Since the glue shrinks after curing, it will pull the housing to cause it to deform, thereby affecting the properties or position of the components of the camera module in the housing, and may also pull the bracket to cause it to deform, thereby affecting the performance and production yield of the camera module and the entire machine. At the same time, the amount of glue used increases, the glue coating area increases, and problems such as glue cracking and glue overflow are prone to occur, which may also cause reliability problems in the camera module.
[0007] In addition, there is an accommodation relationship between the housing and the bracket, and there is an overlapping part in space. Both the housing and the bracket have a certain thickness. This overlapping part plus the assembly gap reserved to avoid interference will further increase the size of the camera module. With the current demand for miniaturization of camera modules and the increasingly compact internal space of electronic equipment, it is also very important to reasonably compress and control the size of the camera module. Summary of the invention

[0011] One advantage of the present application is that it provides a housing, a camera module, an assembly method and an electronic device, wherein the bracket and the housing of the camera module are integrated to reduce the weight of the camera module.
[0012] One advantage of the present application is that it provides a shell, a camera module, an assembly method and an electronic device, wherein the bracket and the shell of the camera module are integrally formed, eliminating the step of gluing and fixing between the bracket and the shell, thereby simplifying the process.
[0013] One advantage of the present application is that it provides a shell, a camera module, an assembly method and an electronic device, wherein the bracket and the shell of the camera module are integrally formed, and there is no need to apply glue between the bracket and the shell to fix them, thereby reducing the risk of glue cracking.
[0014] One advantage of the present application is that it provides a shell, a camera module, an assembly method and an electronic device, wherein the bracket and the shell of the camera module are integrally formed, and the number of parts of the camera module is reduced and the manufacturing cost is reduced by covering the receiving space of the camera module and installing the camera module in the electronic device at the same time.
[0015] One advantage of the present application is that it provides a housing, a camera module, an assembly method and an electronic device, wherein the bracket and the housing of the camera module are integrated, thereby reducing the materials used and lowering the production cost.
[0016] One advantage of the present application is that it provides a shell, a camera module, an assembly method and an electronic device, wherein the bracket and the shell of the camera module are integrally formed, which simplifies the process, reduces the assembly tolerance and improves the yield of the camera module.

[0035] According to the instruction manual Figures 1 to 10 The present application provides a camera module 1, which includes a housing 10 and a semi-finished camera module 70. The semi-finished camera module 70 further includes a base 20, a lens assembly 30, a photosensitive assembly 40, and a circuit assembly 60. The lens assembly 30 is installed in a receiving space 200 of the base 20, the photosensitive assembly 40 is fixed to the base 20, and the circuit assembly 60 is fixed to the base 20. The housing 10 is disposed at least partially around the base 20 to cover the lens assembly 30 located in the receiving space 200.
[0036] The shell 10 and the base 20 may be connected by various methods such as gluing, welding, interference fit, snap-fit, mechanical connection, threading, and hinge. In one optional embodiment, the shell 10 and the base 20 are connected by gluing.
[0037] The housing 10 includes an outer shell 11 and a bracket 12. In some optional embodiments, the outer shell 11 and the bracket 12 are integrally formed to form a whole.
[0038] The base 20 has a light opening 202, and the exit side of the lens assembly 30 faces the light opening 202. The photosensitive component 40 is installed on the base 20, and faces the light opening 202. The photosensitive component 40 is located on the exit side of the lens assembly 30. The light beam emitted from the lens assembly 30 reaches the photosensitive component 40 for imaging.
[0039] Furthermore, the semi-finished camera module 70 of the camera module 1 may further include a lens driving assembly, which is used to drive the lens assembly 30 to move, so as to adjust the focus and achieve the purpose of automatic focusing and / or zooming. The lens driving assembly includes a first driving unit and a second lens driving unit, the first driving unit is installed on the base 20, and the second driving unit is installed on the lens assembly 30, and the first driving unit and the second lens driving unit interact with each other to drive the lens assembly 30 to move relative to the base 20.
[0040] In one embodiment of the driving form of the present application, the lens driving assembly is implemented as a voice coil motor drive, one of the first driving unit and the second lens driving unit is implemented as a magnet, and the other is implemented as a coil.
[0041] In other embodiments of the driving form of the present application, the lens driving assembly is implemented as a piezoelectric motor drive, an SMA (Shape Memory Alloys) drive, a stepper motor or other driving methods.
[0042] For the purpose of convenience of description only, the height or thickness direction of the camera module 1 is defined as the Z axis, and the height direction of the camera module 1 is the thickness direction of the electronic device on which the camera module 1 is installed. The horizontal and vertical directions that are orthogonal to the height direction of the camera module 1 and perpendicular to each other are defined as the X axis and the Y axis, respectively.
[0043] The types of the camera module 1 include upright camera modules, periscope camera modules, other types of telephoto camera modules and other forms.
[0044] In one embodiment of the present application, the camera module 1 is implemented as a periscope camera module as an example for explanation. Figure 1-4 As shown, the semi-finished camera module 70 of the camera module 1 may further include an optical path turning component 50, which is disposed in the receiving space 200 of the base 20, and the exit side of the optical path turning component 50 is disposed opposite to the incident side of the lens assembly 30. The optical path turning component 50 turns the direction of the incident light, and then passes through the lens assembly 30 to reach the photosensitive assembly 40 for imaging.
[0045] The optical path turning component 50 turns the incident light beam along the height direction (first direction Z axis) to be emitted in the direction toward the photosensitive component 40. The optical path turning component 50 and the lens component 30 are sequentially arranged along the propagation direction of the light beam from the light incident side to the light exit side (second direction Y axis).
[0046] The camera module semi-finished product 70 of the camera module 1 may further include an optical path turning drive component for driving the optical path turning component 50 to move, thereby realizing the movement of the optical path turning component 50 in at least one direction. Schematically, the optical path turning drive component drives the optical path turning component 50 to rotate around the horizontal direction (the third direction X-axis) to achieve a nodding motion, correct the position of the optical path turning component 50, and achieve anti-shake; the optical path turning drive component drives the optical path turning component 50 to rotate around the height direction (the first direction Z-axis) to achieve a shaking motion, correct the position of the optical path turning component 50, and achieve anti-shake; the optical path turning drive component drives the optical path turning component 50 to rotate around the light beam propagation direction (the second direction Y-axis), correct the position of the light path turning component 50, and achieve anti-shake; the optical path turning drive component drives the optical path turning component 50 to move along the light beam propagation direction (the second direction Y-axis) to achieve focus adjustment movement; the optical path turning drive component drives the optical path turning component 50 to achieve the aforementioned rotation or movement in one or more directions to achieve anti-shake and / or focus adjustment movement.
[0047] The above example illustrates an example in which the optical path deflection component 50 is disposed on the incident side of the lens assembly 30. In other periscope camera modules, the optical path deflection component 50 is disposed between the lens assembly 30 and the photosensitive assembly 40 to deflect the direction of the light beam at least once after the light beam is emitted from the lens assembly 30 and before it is incident on the photosensitive assembly 40.
[0048] In other parts of the periscope camera module, multiple optical path deflection components 50 are included, at least one of which can be arranged in front of the incident side of the lens assembly 30 to deflect the direction of the light beam at least once before the light beam is incident on the lens assembly 30, and at least one of which can be arranged between the lens assembly 30 and the photosensitive component 40 to deflect the direction of the light beam at least once after the light beam is emitted from the lens assembly 30 and before it is incident on the photosensitive component 40.
[0049] In other periscope camera modules, other lenses may be arranged in front of the incident side of the optical path turning component 50 so that the light beam passes through the lens before entering the optical path turning component 50 .
[0050] In addition, each of the optical path turning components 50 can realize one or more turns on the direction of the light beam, and the present application does not impose any limitation on this.
[0051] The optical path turning drive assembly includes a first optical path turning drive unit and a second optical path turning drive unit. The first optical path turning drive unit is disposed on the base 20, and the second optical path turning drive unit is disposed on the optical path turning assembly 50. The first optical path turning drive unit and the second optical path turning drive unit interact with each other to drive the optical path turning assembly 50 to move.
[0052] In one embodiment of the driving form of the present application, the optical path turning drive component can be implemented as a voice coil motor drive, one of the first optical path turning drive unit and the second optical path turning drive unit can be implemented as a magnet, and the other can be implemented as a coil.
[0053] In other embodiments of the driving form of the present application, the optical path deflection driving component is implemented as a piezoelectric motor drive, an SMA (Shape Memory Alloys) drive, a stepper motor or other driving methods.
[0054] The lens driving assembly and the optical path deflection driving assembly may adopt the same driving form or different driving forms.
[0055] In conjunction with the instruction manual Figures 1 to 10, the housing 10 includes a shell 11 and a bracket 12, and the shell 11 and the bracket 12 together form a component. Among them, the shell 11 is suitable for covering the base 20 to cover at least a part of the internal structure of the semi-finished camera module 70, and the bracket 12 is suitable for the camera module 1 and the electronic device to be installed, so that the camera module 1 is fixed to the electronic device. In an optional embodiment of the present application, the shell 11 of the housing 10 mainly plays the role of controlling stray light and covering the top surface, and the bracket 12 plays the role of peripheral protection. In a specific implementation, the minimum thickness of the bracket 12 is not less than the minimum thickness of the shell 11. Further, it can be implemented that the minimum thickness of the shell 11 corresponds to the material covered and the bracket 12 corresponds to the material covered, which is different, and is formed based on different processing methods, so as to ensure that the minimum thickness of the bracket 12 is not less than the minimum thickness of the shell 11. The housing 10 of the present application integrates the functions of the shell and the bracket of the camera module of the prior art, improves production efficiency, and saves some size, which is conducive to the miniaturization of the camera module 1.
[0056] In the following text, the unnumbered housing and bracket refer to the housing and bracket in the prior art, and the numbered housing 11 and bracket 12 refer to the housing 11 and bracket 12 in the present application.
[0057] During the assembly process of the shell 10 and the semi-finished camera module 70, the fully enclosed shell 10 will block the area on the semi-finished camera module 70 where the circuit component 60 and the photosensitive component 40 need to be connected. If the connection is made first and then the shell 10 is assembled, the debris generated by the assembly and the connection will enter the internal space of the semi-finished camera module 70, which is prone to stains. The solution of directly opening a groove on the shell 10 to expose the area to be connected will affect the structural strength of the shell 10 to a certain extent.
[0058] The present application provides a housing 10, which is divided into two parts: a main body 1001 and a tail 1002. The main body 1001 is firstly sleeved on the outside of at least a part of the internal structure of the semi-finished camera module 70, exposing the area of the circuit component 60 and the photosensitive component 40 to be connected, and then the connection step is performed, and finally the tail 1002 is connected to the main body 1001 and fixed on the base 20. The housing 10 of the present application can shield at least a part of the internal structure of the semi-finished camera module 70 before the connection, so as to prevent debris from entering the internal space of the base 20 for accommodating the internal structure during the assembly and connection process, and reduce the risk of stains.
[0059] The structure of the housing 10 of the present application is described in detail.
[0060] In conjunction with the instruction manual Figures 1 to 10The shell 10 of the present application includes a main body 1001 and a tail 1002. The main body 1001 includes a main body bracket and a main body shell. The main body bracket has a main body side wall, which is suitable for being mounted on the outside of at least a part of the internal structure of the semi-finished camera module 70. The main body shell is provided with a light inlet 104; the tail 1002 is arranged on the light-emitting side of the camera module 1 and surrounds at least a part of the circumference of the semi-finished camera module 70, and is suitable for avoiding the photosensitive component 40 of the camera module 1.
[0061] The main body 1001 and the tail 1002 are arranged along the propagation direction of the light beam from the light incident side to the light exiting side, and are connected to each other to form the housing 10, and the housing 10 has a shell 11 and a bracket 12. The main body 1001 and the tail 1002 can be connected by gluing, welding, interference fit, snap connection, mechanical connection and other methods.
[0062] Specifically, the tail portion 1002 includes a tail bracket, and the main body side wall of the main body bracket and the tail bracket are connected to each other to form the bracket 12 of the shell 10.
[0063] More specifically, the thickness of the main body shell is smaller than the thickness of the bracket 12 of the housing 10 .
[0064] In some embodiments of the present application, the main body shell of the main body 1001 is the shell 11 of the housing 10 .
[0065] In some optional embodiments, the tail portion 1002 includes a tail shell and a tail bracket, the main body side wall of the main body bracket and the tail bracket are interconnected to form the bracket 12 of the shell 10, and the main body shell and the tail shell together form the shell 11 of the shell 10.
[0066] The main body 1001 and the tail 1002 are connected to form a complete housing 10, and the housing 10 includes a cover portion 101 and a side wall portion 102, wherein the cover portion 101 is suitable for covering the base 20, and the side wall portion 102 is suitable for surrounding the outside of the base 20. Further, the cover portion 101 is suitable for covering the opening and / or at least a part of the internal structure of the base 20. From the perspective of the accompanying drawings, the cover portion 101 extends along the plane where the diameter of the light entrance 104 is located or extends approximately along the plane where the diameter of the light entrance 104 is located, and the side wall portion 102 is bent from the outer periphery of the cover portion 101 and extends along the height direction (the first direction Z axis) or approximately along the height direction (the first direction Z axis).
[0067] The cover portion 101 and the side wall portion 102 jointly define a shell covering space 1000 of the shell 10. The shell 10 also has an installation opening. The shell covering space 1000 is connected to an external space through the installation opening. The shell 10 covers the base 20 through the installation opening, and the base 20 is accommodated in the shell covering space 1000.
[0068] The cover portion 101 has a thickness H1 along the height direction (first direction Z axis), and the side wall portion 102 has a thickness H2 along the horizontal direction (third direction X axis) or along the longitudinal direction of the light beam propagation direction (second direction Y axis). The thickness H1 is smaller than the thickness H2, so that the size of the camera module 1 in the height direction (first direction Z axis) is as small as possible to reduce the height of the camera module 1, and can be adapted to the smaller thickness of the electronic device, meeting the requirements of miniaturization of the camera module. Furthermore, the thickness of any position of the cover portion 101 does not exceed the thickness of any position of the side wall portion 102. Since the main function of the cover portion 101 is to cover the internal structure of the camera module, its thickness dimension only needs to ensure that the cover portion 101 can be formed, so H1 can be as small as possible while ensuring strength, so as to reduce the size of the camera module 1. The side wall portion 102 has a certain thickness to ensure its mechanical strength.
[0069] The side wall portion 102 is sleeved on the outside of the base 20. Further, in some examples of the present application, at least a portion of the bottom of the side wall portion 102 is flush with at least a portion of the bottom of the base 20. In other words, there is a flush portion of the lower end surface of the side wall portion 102 that is flush with the lower end surface of the base 20, so as to bias the installation of the housing 10 on the base 20 and improve the assembly accuracy in the height direction (first direction Z axis). In other examples of the present application, at least a portion of the bottom of the side wall portion 102 further protrudes downward relative to the bottom of the base 20.
[0070] The side wall portion 102 is provided with a mounting structure 103, and the mounting structure 103 is suitable for the camera module 1 to be installed on the electronic device, and / or suitable for fixing the camera module and other camera modules to form a multi-camera module.
[0071] The mounting structure 103 is suitable for the camera module 1 to be mounted on the electronic device, or is suitable for fixing the camera module 1 and other camera modules to form a multi-camera module.
[0072] In one embodiment of the present application, the housing 10 is installed on the base 20 of one camera module 1 to form a housing 11 of the camera module 1; in one embodiment of the present application, the housing 10 is installed on the bases 20 of multiple camera modules, that is, the housing covering space 1000 can accommodate multiple camera modules 1 to form multiple housings 11 of the camera modules 1. In other words, the housing 11 and the bracket 12 of a single camera module can be designed in an integrated manner, and the housing 11 and the bracket 12 of multiple camera modules can also be designed in an integrated manner.
[0073] The mounting structure 103 includes a positioning portion and a positioning hole 1031. The positioning portion is formed by protruding outward from the outer surface of the side wall portion 102, and the positioning hole 1031 is opened in the positioning portion to form a through hole. The positioning hole 1031 is aligned with the mounting hole on the electronic device, and then fixed by a fixing member (such as a screw) so that the camera module 1 is fixed to the electronic device. Similarly, the positioning hole 1031 can be aligned with the positioning hole of the bracket of other camera modules and fixed so that the camera module 1 is connected to other camera modules.
[0074] In other examples, the mounting structure 103 can also be a snap-fit structure, and the electronic device can be positioned and snap-fitted. In other examples, the camera module 1 and the electronic device can be snapped together at corresponding positions and fixed by glue. In other examples, other suitable fixing methods can also be implemented.
[0075] The housing 10 also has a light inlet 104, and the incident light beam enters the interior of the camera module 1 from the light inlet 104 and passes through the lens assembly 30. In some examples, the housing 10 also has a light outlet 105, and the light beam is emitted from the light outlet 105 to reach the photosensitive component 40, and an image is formed at the photosensitive component 40. The lens assembly 30 is installed between the light inlet 104 and the light outlet 105, and the light outlet 105 is located between the lens assembly 30 and the photosensitive component 40. Furthermore, the optical path turning component 50 is located between the light inlet 104 and the light outlet 105, and before the light beam reaches the photosensitive component 40, the light beam can be folded by the optical path turning component 50 to achieve optical path folding.
[0076] The housing 10 has an inner surface 106 and an outer surface 107, wherein the inner surface 106 faces the internal structure of the camera module 1, and the outer surface 107 faces the outside of the camera module 1. An inner connection structure is formed between the inner surface 106 and the internal structure of the camera module 1, and an inner and outer connection structure is formed between the outer surface 107 and the external structure of the camera module 1. When the housing 10 and the base 20 are fixed, the inner connection structure is formed between the inner surface 106 and the base 20, so that the camera module 1 forms a whole; when the housing 10 and the electronic device are fixed, the outer connection structure is formed between the outer surface 107 and the electronic device, so that the camera module 1 is installed in the electronic device. Thus, the position of the camera module 1 in the electronic device is positioned by the cooperation of the inner and outer surfaces of the housing 10, thereby improving the accuracy of assembly positioning.
[0077] The inner surface 106 is defined by the inner surface of the housing 11 and the inner surface of the bracket 12 , and the outer surface 107 is defined by the outer surface of the housing 11 and the outer surface of the bracket 12 .
[0078] In some examples, the inner surface 106 provides at least one bonding surface for cooperating with the base 20 for bonding and fixing, so that the housing 10 and the base 20 are fixed. Further, the bonding surface can be formed on the portion of the inner surface 106 located on the side wall portion 102.
[0079] Next, the specific structures of the shell 11 and the bracket 12 of the housing 10 are further described.
[0080] like Figures 5 to 8 As shown, the main body 1001 includes the main body shell and the main body bracket, and the tail 1002 includes the tail bracket. The main body shell forms the shell 11 of the shell 10, and the main body bracket and the tail bracket are interconnected to form the bracket 12 of the shell 10.
[0081] The housing 11 includes an integrally formed housing cover wall 111 and a housing side wall 112, at least a portion of the housing side wall 112 is insert-molded to form the main body bracket, and the housing cover wall 111 extends along the plane where the diameter of the light entrance 104 is located or substantially along the plane where the diameter of the light entrance 104 is located. The housing side wall 112 extends from the outer periphery of the housing cover wall 111 along the height direction (first direction Z axis).
[0082] The housing cover wall 111 of the main housing forms the aforementioned cover portion 101, which is suitable for covering the receiving space 200 of the base 20. The light inlet 104 is opened on the housing cover wall 111, facing the direction of light incidence.
[0083] The bracket 12 and the shell cover wall 111 are stacked along the height direction (first direction Z axis) to form the aforementioned side wall portion 102 so as not to overlap with the shell side wall 112 to avoid increasing the thickness of the shell side wall 112 at the bracket 12 .
[0084] The connection between the bracket 12 and the housing 11 is formed between the top of the bracket 12 and the bottom of the housing side wall 112 of the housing 11, wherein the top of the bracket 12 faces the side of the housing cover wall 111. A bending portion 113 is formed between the housing cover wall 111 and the housing side wall 112, and the thickness of the housing cover wall 111 and the housing side wall 112 are close or the same, so that the bending portion 113 has a smooth transition, reducing the difficulty of molding. Furthermore, the thickness of the housing side wall 112 is less than the thickness of the bracket 12, reducing the wall thickness of a part of the side wall portion 102 of the housing 10, which is conducive to reducing the weight of the housing 10.
[0085] In another embodiment of the present application, the top of the bracket 12 is formed at the outer periphery of the housing cover wall 111 of the housing 11, that is, the housing 11 does not have the housing side wall 112. Compared with the prior art, the thickness of the housing side wall 112 of the housing 11 is omitted at the bracket 12.
[0086] Therefore, when the shell 11 and the bracket 12 are integrally formed to form the housing 10, the thickness of the shell 11 can be omitted at the overlap of the bracket 12 and the shell 11, or the bracket 12 and the shell 11 are stacked in the height direction (first direction Z axis), saving the thickness of the shell 11 in the horizontal and vertical dimensions. Further, since the shell 11 and the bracket 12 are integrally formed, compared with the separate bracket and shell in the prior art, the use of the shell 10 eliminates the step of assembling the bracket 12 to the shell 11, and also eliminates the glue between the bracket 12 and the shell 11.
[0087] That is to say, in terms of size, the use of an integrated shell 10 is conducive to reducing the size of the camera module 1, especially the lateral size (third direction X-axis) and longitudinal size (second direction Y-axis) of the light beam propagation direction; in terms of assembly, the use of an integrated design of the shell 10 simplifies the assembly process and improves production efficiency; in terms of reliability, the use of an integrated design of the shell 10 eliminates the need for glue and avoids reliability risks brought by glue, such as but not limited to problems such as bracket falling off, glue cracking, bracket deformation, and shell 11 deformation.
[0088] Specifically, regarding the reliability risk of glue, the cracking of glue will cause the glue to break or fail, which will cause the structure originally connected by glue to lose stability, and reduce the strength, rigidity, durability, etc. of the connection structure. If the camera module 1 is assembled on an electronic device, and the bracket and the electronic device are fixed, the connection structure between the bracket and the housing 11 fails, the camera module 1 may become loose or displaced, resulting in a degradation of the performance of the camera module 1 or even failure. By utilizing the integrated housing 10 of the present application, the functions of the housing 11 and the bracket 12 of the camera module 1 are realized, and the glue between the bracket and the housing 11 is omitted, which can reduce the risk points of the camera module 1 and help improve the finished product yield of the camera module 1.
[0089] Furthermore, the glue between the bracket and the housing 11 is omitted, which can specifically omit the glue selection and verification, glue position selection and verification, glue quantity (such as total glue quantity, glue width, glue length, glue thickness, etc.) verification, tooling and jig production and verification of the glue drawing process, glue coating and curing time, etc., and also eliminates the problem of glue seepage affecting the appearance. Therefore, omitting the glue between the bracket and the housing 11 can save time for design and development, verification, production, assembly, etc., improve the design and development efficiency, production efficiency and production yield of the camera module 1, and improve the appearance yield of the camera module 1.
[0090] In addition, in the camera module of the prior art, the glue will be pulled on the shell and the bracket due to the shrinkage rate after curing, and the shell is relatively thin, which will cause the shell to be pulled and deformed. The shell is arranged on the outside of the base, and the shell is pulled and deformed, which may cause the base to be deformed by force, thereby affecting the shape of the receiving space of the base, and the position and / or shape of the components located in the receiving space, etc., affecting the performance of the camera module. Therefore, after avoiding the glue between the bracket and the shell, the deformation problem caused by the shrinkage of the glue curing is also avoided, the assembly tolerance is reduced, and the yield rate of the camera module is improved.
[0091] Specifically in terms of assembly, first, the assembly process is simplified, and the two assemblies of the housing and the bracket in the prior art are optimized to a single assembly of the housing 10 of the present application, eliminating the glue setting and glue curing processes, and reducing assembly tolerances. In addition, the integration of the housing 11 and the bracket 12 can also optimize the eccentricity problem of the camera module caused by the bracket assembly in the prior art.
[0092] Specifically, in the camera module of the prior art, there is an assembly gap between the bracket and the housing, which will cause the housing together with the base of the camera module and its internal structure to be offset in the bracket, causing the light hole provided on the housing to be offset relative to the bracket. Therefore, when the bracket is assembled to the housing, the light hole of the camera module may have been offset. After the camera module is assembled to the electronic device, the offset may be more serious, which causes the light hole of the electronic device and the light hole of the camera module to be offset, resulting in an eccentricity problem of the camera module. In addition, the glue between the bracket and the housing will also affect the relative position between the bracket and the housing, aggravating the offset problem between the light hole and the bracket, making the final light hole of the electronic device and the light hole of the camera module offset more serious.
[0093] The housing 10 of the present application adopts an integrated design of the shell 11 and the bracket 12, and the light inlet 104 of the shell 11 is fixed at the position of the shell 10, and the relative position between the light inlet 104 and the bracket 12 remains unchanged, thereby avoiding the offset problem of the shell 11 and the bracket 12 in the camera module of the prior art. In other words, the relative position between the light inlet 104 of the shell 10 and the mounting structure 103 remains unchanged. Therefore, when the camera module 1 is installed on the electronic device, the alignment of the light inlet 104 of the camera module 1 and the light hole of the electronic device can be achieved through the precise alignment of the mounting structure 103 and the electronic device, thereby avoiding the eccentricity problem of the camera module 1 caused by the offset of the light inlet 104, thereby improving the assembly yield of the camera module 1. Furthermore, the assembly eccentricity problem of the camera module 1 can be controlled by controlling the manufacturing tolerance of the distance between the light inlet 104 and the mounting structure 103; the assembly eccentricity problem of the camera module 1 can be controlled by controlling the manufacturing tolerance of the distance between the light inlet 104 and the bracket 12.
[0094] It is understandable that, according to the design requirements of the camera module 1, the shell 10 and the housing 11 may be subjected to certain surface treatments, including but not limited to electroplating, laser engraving, black coating, spraying, silk screen printing, coating, etc., to meet the requirements of optical performance, magnetic shielding, stray light improvement, structural reinforcement, and extended service life. For example, surface treatments such as laser engraving and black coating may be performed on specific areas of the surface of the housing cover wall 111 to improve stray light. Figure 5 As shown, the inner surface of the housing 11 has a surface treatment area 109 .
[0095] The bracket 12 is sleeved on the outside of the base 20 and surrounds the base 20 for one week to form a protective structure outside the camera module 1, which can provide physical protection for the camera module 1 and prevent damage caused by dropping, impact or other external forces. The bracket 12 is used to fix the camera module 1 at a specific position in the electronic device, ensure its accurate relative position with other components, and thus ensure the accuracy and stability of image capture. When the camera module 1 is working, heat may be generated, and the bracket 12 can assist in heat dissipation, help the camera module 1 work at an appropriate temperature, and extend its service life. The bracket 12 can enhance the structural stability of the camera module 1. In some possible implementation manners, the bracket 12 can provide a certain degree of electromagnetic shielding to prevent electromagnetic interference from affecting the imaging quality.
[0096] In some examples of the present application, the bracket 12 is formed by surrounding for one week and includes a first side wall portion 121, a second side wall portion 122, a third side wall portion 123 and a fourth side wall portion 124 that are sequentially connected. From the perspective of the accompanying drawings of the specification, the first side wall portion 121 and the third side wall portion 123 extend and are distributed along the longitudinal direction (the second direction Y-axis) of the light beam propagation direction, and are opposite to each other in the transverse direction (the third direction X-axis) and the second side wall portion 122 and the fourth side wall portion 124 extend and are distributed along the transverse direction (the third direction X-axis) and are opposite to each other in the longitudinal direction (the second direction Y-axis) of the light beam propagation direction. The first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124 respectively have heights that extend and are distributed along the height direction (the first direction Z-axis).
[0097] Among them, the specific shape of the bracket 12 can be determined in combination with the design requirements of the camera module 1 and the adaptation requirements of the electronic device.
[0098] In other examples of the present application, the bracket 12 is not formed by surrounding for one week. The bracket 12 has at least one opening and is arranged on three sides of the housing 11. Further, in some examples, the position of the opening is adapted to the position of the photosensitive component 40. In some examples, the position of the opening is different from the position of the photosensitive component 40.
[0099] The shape of the bracket 12 can be frame type, L type, U type, "mouth" type, etc.
[0100] In some embodiments of the present application, the housing 10 can be implemented as two parts sequentially arranged along the light beam propagation direction, including a main body portion 1001 and a tail portion 1002. From the perspective of the accompanying drawings of the specification, such as Figures 2 to 7As shown, the main body 1001 covers at least a portion of the internal structure of the semi-finished camera module 70, and the tail 1002 surrounds the photosensitive component 40 located on the light-emitting side, wherein a portion of the outer shell 11 and a portion of the bracket 12 forming the main body 1001 jointly define a main space 1100, and another portion of the outer shell 11 and another portion of the bracket 12 forming the tail 1002 jointly define a receiving space 1200. During assembly, the internal structure assembly of the base 20 covered by the main space 1100 and the internal structure assembly of the base 20 covered by the receiving space 1200 can be carried out simultaneously. After the internal structure assembly is completed, the main body 1001 and the tail 1002 are assembled, so that the shell 10 is more compatible with the actual assembly operation, thereby further improving the assembly efficiency of the camera module 1.
[0101] Among them, whether the assembly of the main body 1001 and the tail 1002 is synchronized is determined by the completion time of the internal structure assembly of the main space 1100 and the completion time of the internal structure assembly of the accommodating space 1200, and can be adjusted in combination with the actual assembly operation process of the camera module 1.
[0102] like Figure 2-4 As shown, the main body 1001 is the portion of the shell 10 along the longitudinal direction (second direction Y axis) of the light beam propagation direction from the second side wall portion 122 to the light opening 202, that is, the first side wall portion 121, the third side wall portion 123 and the shell 11 along the longitudinal direction (second direction Y axis) of the light beam propagation direction from the second side wall portion 122 to the light opening 202, and the second side wall portion 122 extending and distributed along the transverse direction (third direction X axis) are integrally formed; the tail portion 1002 is the portion of the shell 10 along the longitudinal direction (second direction Y axis) of the light beam propagation direction from the light opening 202 to the fourth side wall portion 124, that is, the first side wall portion 121, the third side wall portion 123 and the shell 11 along the longitudinal direction (second direction Y axis) of the light beam propagation direction from the light opening 202 to the fourth side wall portion 124, and the fourth side wall portion 124 extending and distributed along the transverse direction (third direction X axis) are integrally formed. The heights of the main body 1001 and the tail 1002 extending in the height direction (the first direction Z axis) remain unchanged.
[0103] Specifically, the main body 1001 and the tail 1002 are connected by being nested along the optical path direction, and are fixed by injecting glue at the nesting position. Figure 3 and Figure 7As shown, the main body bracket of the main body 1001 located at the connection is protruded toward the tail part 1002 along the tail end of the optical path to form an embedded part 10011 of the main body 1001, and the tail bracket of the tail part 1002 located at the connection is provided with a nesting part 10021 matched with the embedded part 10011 along the head end of the optical path. When the main body 1001 and the tail part 1002 are connected, the nesting part 10021 is aligned with the embedded part 10011, nested and injected with glue for curing, so as to realize the positioning and assembly of the tail part 1002 on the main body 1001.
[0104] Among them, after the nesting part 10021 is nested and connected with the embedded part 10011, the inner side surface of the nesting part 10021 is connected to the outer side surface of the embedded part 10011, and the outer side surface of the nesting part 10021 is flush with the inner side surface and the outer side surface of the bracket 12 of the main body 1001, that is, the thickness of the nesting connection between the nesting part 10021 and the embedded part 10011 in the horizontal direction (third direction X-axis) is equal to the thickness of the bracket 12 in the horizontal direction (third direction X-axis), so as to ensure the mechanical strength of the shell 10 formed after the nesting connection and avoid increasing the thickness of the shell 10 at the nesting connection.
[0105] Specifically, the thickness of the embedded portion 10011 is consistent with the thickness of the main shell, that is, it is smaller than the thickness of the bracket 12 of the shell 10, so as to control the thickness after the nested connection to be consistent with the thickness of the bracket 12 of the shell 10.
[0106] In some examples, the embedding portion 10011 of the main body 1001 and the nesting portion 10021 of the tail 1002 are nested and bonded, and then welded to enhance the connection strength between the main body 1001 and the tail 1002. The welding process may be laser welding, solder ball welding, etc.
[0107] The light inlet 104 is arranged on the main body 1001, and the light outlet 105 is arranged on the rear end of the main body 1001. From the perspective of the drawings in the specification, the light inlet 104 is arranged on the cover part 101 of the main body 1001, and the light outlet 105 is arranged between the rear end of the main body 1001 along the longitudinal direction (the second direction Y axis) of the light beam propagation direction and the photosensitive component 40.
[0108] In some examples, the base 20 has a mounting seat 204 at the rear of the optical path, the light port 202 is formed on the mounting seat 204, that is, the light outlet 105 is arranged on the mounting seat 204, and the photosensitive component 40 is installed on the light outlet side of the mounting seat 204, such as Figure 2-5 As shown, the light beam is emitted from the light outlet 105 , reaches the photosensitive component 40 , and forms an image on the photosensitive component 40 .
[0109] Among them, the mounting seat 204 is located at the rear end of the main body 1001 and is connected to the cover part 101 of the main body 1001, forming a closed space from the light inlet 104 to the light outlet 105, so as to isolate the material flow between the internal structure of the camera module 1 and the outside world, and avoid the entry of debris and dust into the internal space of the base 20 during the subsequent processing of assembly and welding, causing the risk of stains, and ultimately affecting the imaging of the camera module 1.
[0110] In other examples of the present application, the shell 10 is the main body 1001, excluding the tail portion 1002. The tail end of the main body 1001 along the optical path abuts against the light incident side of the mounting seat 204 of the base 20 to form a closed space from the light entrance 104 to the light exit 105 to accommodate the internal structure on the base 20 except for the photosensitive component 40. The photosensitive component 40 is installed on the light exit side of the mounting seat 204 to constitute the camera module 1.
[0111] In order to further cooperate with the actual assembly operation of the camera module 1, the bracket 12 portion where the main body 1001 and the tail 1002 are connected is provided with a groove suitable for avoiding the structure to be welded. From the perspective of the accompanying drawings, the groove formed between the main body 1001 and the tail 1002 is Figure 9-10 The connection area 15 shown is suitable for avoiding the pins of the circuit assembly 60 and the connection area of the circuit board 41 in the photosensitive assembly 40. In the embodiment where the main body 1001 and the tail 1002 are welded after being nested, the welding of the nested connection and the welding of the connection area 15 can be performed simultaneously, further improving the assembly efficiency.
[0112] The positional relationship between the housing side wall 112 of the housing 11 and the bracket 12 is specifically described. The housing 11 has a first side surface 1101. In the embodiment in which the housing 11 has the housing side wall 112, the first side surface 1101 is formed on the inner side surface of the housing side wall 112 and faces the base 20. The bracket 12 has a second side surface 1201. The second side surface 1201 is formed on the inner side surface of the bracket 12 and faces the base 20.
[0113] In some examples, the first side surface 1101 and the second side surface 1201 are flush and aligned along the height direction (first direction Z axis), so that the housing 10 provides a flat inner surface 106, and the inner surface 106 is suitable for matching with the base 20, and the base 20 provides an outer peripheral side surface 201 without step difference, and the inner surface 106 and the outer peripheral side surface 201 are adapted. Further, the first side surface 1101 and the second side surface 1201 are flush, which is conducive to the molding and demolding of the housing 10. In the integrated die-casting molding method, the first side surface 1101 and the second side surface 1201 are flush, which is convenient for demolding, and is conducive to simplifying mold design, improving production yield, and reducing costs.
[0114] In some examples, the first side surface 1101 and the second side surface 1201 are not flush, forming a step difference, and the first side surface 1101 is closer to the outside than the second side surface 1201, that is, farther away from the base 20. The gap between the first side surface 1101 and the base 20 is smaller than the gap between the second side surface 1201 and the base 20.
[0115] In one embodiment of the manufacturing of the housing 10 of the present application, the shell 11 and the bracket 12 of the housing 10 are integrally formed by combining metal material and plastic material. Further, the shell 11 is made of metal material, and injection molding is performed around a portion of the shell 11 to form the bracket 12, thereby obtaining the housing 10 integrally formed as a single part.
[0116] The housing side wall 112 of the housing 11 is provided with a coupling hole 1120, and the coupling hole 1120 runs through the housing side wall 112, and the number of the coupling holes 1120 can be multiple. The molding material used to mold the bracket 12 is combined with the inner wall of the coupling hole 1120 to strengthen the bonding strength between the two parts, that is, to strengthen the connection strength between the housing 11 and the bracket 12.
[0117] In one embodiment of the housing 11 of the present application, the housing side wall 112 includes a first housing side wall 1121, a second housing side wall 1122, and a third housing side wall 1123, and the first housing side wall 1121, the second housing side wall 1122, and the third housing side wall 1123 are sequentially connected, formed around three sides of the housing cover wall 111, and embedded to form the main body bracket, thereby forming the main body 1001. At least one or all of the first housing side wall 1121, the second housing side wall 1122, and the third housing side wall 1123 are provided with the combining hole 1120, and further, a plurality of the combining holes 1120 are provided.
[0118] In another embodiment of the housing 11 of the present application, the housing side wall 112 includes a first housing side wall 1121, a second housing side wall 1122, a third housing side wall 1123 and a fourth housing side wall 1124, and the first housing side wall 1121, the second housing side wall 1122, the third housing side wall 1123 and the fourth housing side wall 1124 are formed around the four sides of the housing cover wall 111. The bracket 12 is formed around the first housing side wall 1121, the second housing side wall 1122, the third housing side wall 1123 and the fourth housing side wall 1124. At least one or all of the first housing side wall 1121, the second housing side wall 1122, the third housing side wall 1123 and the fourth housing side wall 1124 are provided with the combining hole 1120.
[0119] like Figure 8 As shown, the shell side wall 112 includes a combining portion 1125, and the combining hole 1120 is arranged on the combining portion 1125. After the shell 11 is molded, the bracket 12 is molded around the combining portion 1125, so that the molding material enters the combining hole 1120, the molding material and the inner wall of the combining hole 1120 are combined, and the bracket 12 is molded together on the surface of the combining portion 1125 and the combining hole 1120.
[0120] In some examples, the bracket 12 is molded on both the inner and outer sides of the shell side wall 112. That is, a portion of the bracket 12 is molded on both the inner and outer surfaces of the shell side wall 112. At least a portion of the shell side wall 112 is wrapped in the bracket 12. The molding material passes through the coupling hole 1120, and the bracket 12 is molded on the inner surface, the outer surface of the coupling portion 1125, and the coupling hole 1120. In some examples, the bracket 12 is molded on the outer side of the shell side wall 112. That is, the molding material molds the bracket 12 on the outer surface of the coupling hole 1120 and the coupling portion 1125.
[0121] The inner side of the shell side wall 112 faces the interior of the shell 10 , that is, toward the internal structure of the camera module 1 , and the outer side of the shell side wall 112 faces the outside of the shell 10 , that is, toward the external space of the camera module 1 .
[0122] From the perspective of the drawings of the specification, the first shell side wall 1121 and the third shell side wall 1123 extend and distribute along the longitudinal direction (second direction Y axis) of the light beam propagation direction, and are opposite to each other along the transverse direction (third direction X axis). The second shell side wall 1122 extends and distributes along the transverse direction (third direction X axis). In the example where the fourth shell side wall 1124 is provided, the second shell side wall 1122 and the fourth shell side wall 1124 are opposite to each other along the longitudinal direction (second direction Y axis) of the light beam propagation direction.
[0123] In the example where the fourth shell side wall 1124 exists in the shell 11, the bracket 12 forms the first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124 on the first shell side wall 1121, the second shell side wall 1122, the third shell side wall 1123 and the fourth shell side wall 1124, respectively, so that the first shell side wall 1121, the second shell side wall 1122, the third shell side wall 1123 and the fourth shell side wall 1124 are respectively embedded in the first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124 to form an embedded relationship.
[0124] Furthermore, in some examples of the present application, the shell 10 includes a main body 1001 and a tail portion 1002 arranged along the propagation direction of the light beam, and the main body 1001 and the tail portion 1002 are both obtained by injection molding by the above-mentioned embedded molding method using the shell 11 as an inlay. The shell 11 has a fourth shell side wall 1124, and the shell 11 is interrupted at the position of the first shell side wall 1121 and the third shell side wall 1123 corresponding to the light outlet 105 to form a main body shell and a tail shell. The main body shell and the tail shell are molded around the circumference of the camera module semi-finished product 70, and are respectively used for embedded injection molding of the main body 1001 and the tail portion 1002 to form the main body 1001 and the tail portion 1002.
[0125] Among them, the main body shell and the tail shell are respectively embedded in the injection molding cavity of the main body 1001 and the injection molding cavity of the tail 1002, and the injection molding of the main body 1001 and the tail 1002 can be carried out simultaneously, further improving the production efficiency.
[0126] Specifically, the main shell includes the second shell side wall 1122 and a part of the shell cover wall 111 from the second shell side wall 1122 to the light outlet 105, the first shell side wall 1121 and the third shell side wall 1123, and the tail shell includes the fourth shell side wall 1124 and another part of the shell cover wall 111.
[0127] More specifically, when the first shell side wall 1121 and the third shell side wall 1123 of the main body shell form the first side wall portion 121 and the third side wall portion 123, a portion of the first shell side wall 1121 and the third shell side wall 1123 along the tail end of the optical path is retained without being surrounded by injection molding to form the embedded portion 10011 of the main body 1001, and an insert with the same shape and thickness as the embedded portion 10011 is added to the head end of the tail portion 1002 of the tail shell before injection molding to form the nested portion 10021 of the tail portion 1002.
[0128] In some embodiments, the portion of the main body shell that is retained but not surrounded by injection molding can be used as an injection molding inlay for the nested portion of the tail portion 1002. A metal release agent is applied to the retained portion so that the nested portion 10021 can be injection molded and demolded in the shape of the embedded portion 10011.
[0129] In the example where the fourth shell side wall 1124 does not exist in the shell 11, the bracket 12 forms the first side wall portion 121, the second side wall portion 122 and the third side wall portion 123 on the first shell side wall 1121, the second shell side wall 1122 and the third shell side wall 1123, respectively, so that the first shell side wall 1121, the second shell side wall 1122 and the third shell side wall 1123 are respectively embedded in the first side wall portion 121, the second side wall portion 122 and the third side wall portion 123 to form an embedded relationship.
[0130] Specifically, in the example where the shell 10 does not have the tail portion 1002, the shell 10 is the main body 1001, and the shell 11 does not have a tail shell, that is, the bracket 12 forms the first side wall portion 121, the second side wall portion 122 and the third side wall portion 123 of the main body 1001 on the first shell side wall 1121, the second shell side wall 1122 and the third shell side wall 1123 respectively.
[0131] In some examples of the present application, there is no embedding relationship between the fourth side wall portion 124 and the housing side wall 112 of the housing 11. Specifically, there is a gap between the fourth side wall portion 124 and the housing cover wall 111 of the housing 11 to form a gap space 108.
[0132] Furthermore, in the example where the housing 10 includes the main body 1001 and the tail 1002, the housing 11 does not have the fourth housing side wall 1124, and the bracket 12 forms the first side wall 121, the second side wall 122 and the third side wall 123 of the main body 1001 respectively with the first housing side wall 1121, the second housing side wall 1122 and the third housing side wall 1123 of the housing 11, and there is no embedding relationship between the tail 1002 and the housing side wall 112 of the housing 11, that is, the tail 1002 does not have a tail housing, and the tail 1002 is directly obtained by injection molding. Specifically, after the main body 1001 and the tail 1002 are connected, they are enclosed together to form a spacing space 108, which is suitable for accommodating the photosensitive component 40 of the camera module 1.
[0133] It can be understood that the "integrated molding" in the present application refers to forming a single component, such as the shell 10 is a single component, and is not limited to one-time molding during the manufacturing process. It can be molded once or multiple times to obtain the integrally molded shell 10 of the present application.
[0134] Next, the embodiment of the combining portion 1125 of the present application is further described. The combining portion 1125 is a portion of the housing 11 suitable for combining with the bracket 12 .
[0135] The above content introduces an implementation of the combination portion 1125, and the combination portion 1125 is located on the shell side wall 112 of the shell 11. The shell side wall 112 is a portion located on the periphery of the shell cover wall 111, and at least a portion of the shell side wall 112 is the combination portion 1125. The shell cover wall 111 and the shell side wall 112 jointly define the light outlet 105. The bracket 12 is formed around the combination portion 1125 to form the first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124 that surround the periphery and are connected in sequence. Among them, a spacing space 108 is formed between the shell 11 and the fourth side wall portion 124, which is suitable for avoiding the photosensitive component 40. Further, a portion of the first side wall portion 121, the shell 11, a portion of the third side wall portion 123 and the first side wall portion 121 are connected in sequence to define the spacing space 108.
[0136] The mounting structure 103 is formed by injection molding to form the positioning portion and the positioning hole 1031. The number of the mounting structure 103 can be one or more. In the example where the number is multiple, the mounting structure 103 can be distributed in one or more of the first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124 of the bracket 12, and multiple mounting structures 103 can be set in the same one of the first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124.
[0137] In another embodiment of the present application, refer to the attached Figure 8 As shown in the figure, the combining portion 1125 includes a first combining portion 11251 and a second combining portion 11252, and the first combining portion 11251 is provided with the combining hole 1120. The first combining portion 11251 is formed on the side wall 112 of the housing. The second combining portion 11252 is integrally extended from the first combining portion 11251. Further, the spacing space 108 is defined between the second combining portion 11252 and the housing 11. That is to say, unlike the aforementioned embodiment, the second combining portion 11252 is added, which is suitable for combining with the fourth side wall portion 124, the first side wall portion 121 and the third side wall portion 123 of the bracket 12. The second combining portion 11252 and the photosensitive component 40 avoid each other.
[0138] The combining portion 1125 also includes a third combining portion 11253, which is arranged on the first combining portion 11251 and / or the second combining portion 11252. Further, the third combining portion 11253 protrudes from the first combining portion 11251 and / or the second combining portion 11252, and its extension direction is perpendicular to the height direction (first direction Z axis), and can be implemented to extend horizontally (third direction X axis) and / or longitudinally along the propagation direction of the light beam (second direction Y axis).
[0139] The positioning hole 1031 of the mounting structure 103 is arranged on the third combining part 11253, and the positioning portion of the mounting structure 103 is formed around the third combining part 11253. The positioning portion surrounds at least a portion of the third combining part 11253, exposing the positioning hole 1031. Furthermore, a portion of the third combining part 11253 surrounding the positioning hole 1031 is exposed from the positioning portion. When the third combining part 11253 is made of metal material, that is, the mating surface of the inner wall defining the positioning hole 1031 is a metal surface. When the camera module 1 is fixed to the electronic device, the mating surfaces of the fixing part and the metal cooperate to avoid the chipping problem caused by the plastic material.
[0140] The number of the third combining portion 11253 may be one or more. In the example where the number is multiple, the third combining portion 11253 may be distributed in one or more of the first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124 of the bracket 12, and multiple third combining portions 11253 may be provided in the same one of the first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124.
[0141] In the embodiment where the shell 10 is implemented as the main body 1001 and the tail part 1002, the first combining portion 11251 and the second combining portion 11252 are respectively located on the main body shell and the tail shell, and a plurality of the third combining portions 11253 are arranged on the main body shell and the tail shell.
[0142] Among them, there are at least two third combining parts 11253 on the first combining part 11251 of the main body shell, which are respectively located on the second shell side wall 1122 extending and distributed along the transverse direction (the third direction X-axis) and the first shell side wall 1121 and / or the third shell side wall 1123 extending and distributed along the longitudinal direction (the second direction Y-axis) of the light beam propagation direction, so as to ensure that there is at least one positioning hole 1031 of the mounting structure 103 on the main body 1001 formed by injection molding along the transverse direction (the third direction X-axis) and the longitudinal direction (the second direction Y-axis) of the light beam propagation direction; there is at least one third combining part 11253 on the second combining part 11252 of the tail shell, so as to ensure that there is at least one positioning hole 1031 of the mounting structure 103 on the tail 1002 formed by injection molding.
[0143] Specifically, the multiple mounting structures 103 on the main body 1001 and the tail portion 1002 are arranged at different heights in the height direction (first direction Z axis), that is, the multiple third combining parts 11253 are arranged at different heights in the height direction (first direction Z axis), so that the injection-molded main body 1001 and the tail portion 1002 can position the height of the shell 10 in the height direction (first direction Z axis) through the positioning hole 1031 during assembly.
[0144] The bracket 12 is also provided with the connection area 15. In some embodiments of the present application, the connection area 15 is located between the main body 1001 and the tail portion 1002, and is surrounded by a pair of relatively arranged notches respectively located at the tail side of the main body 1001 and the front side of the tail portion 1002. Before injection molding, inserts are placed in the injection cavity of the main body 1001 and the injection cavity of the tail portion 1002 at positions corresponding to the notches, so that the connection area 15 is integrally formed with the shell 10.
[0145] In some examples, the injection cavity of the main body 1001 and the injection cavity of the tail 1002 are arranged in the same mold, and the two injection cavities are independent of each other and not connected, so that the embedding injection molding process of the main body 1001 and the tail 1002 can be carried out simultaneously.
[0146] In other examples, the injection cavity of the main body 1001 and the injection cavity of the tail 1002 are connected to each other, and corresponding barriers are placed at the connection position between the main body 1001 and the tail 1002 before injection molding, and after the main body shell and the tail shell are embedded, the main body 1001 and the tail 1002 are injection molded in sequence.
[0147] In the aforementioned process, the housing 11 is first formed by a metal material forming process, and then the bracket 12 is injection molded around the housing 11 to obtain the housing 10. Therefore, an insert molding process can be used to injection mold around the metal material to obtain the housing 10 of the present application. Among them, the metal material can be but not limited to steel-containing materials, aluminum alloys, phosphor bronze, titanium alloys, iron-based materials, zinc alloys, magnesium alloys, tin-based alloys, copper alloys, etc. The steel-containing material can be but not limited to stainless steel, SPCC (Steel Plate Cold Commercial, cold-rolled carbon steel sheet), etc. The process of forming the metal material can include but is not limited to metal stamping, integrated die casting, metal casting, metal forging, powder metallurgy, metal injection molding (MIM, Metal Injection Molding), stretching, secondary stretching, etc. Further, the metal stamping process can be used to form the housing 11, so that the housing 11 can have a thinner wall thickness and minimize the size of the camera module 1.
[0148] Taking the use of stainless steel material to stamp and form the housing 11 as an example, the wall thickness of the housing 11 can be controlled at about 0.2 mm. On the basis of ensuring the molding of the housing 11, the wall thickness is reduced as much as possible to reduce the size of the camera module 1 in the height direction (first direction Z axis). At the same time, since the housing 11 and the bracket 12 are integrally formed, the wall thickness of the housing 11 can be saved on one side in the horizontal direction (third direction X axis) and the longitudinal direction of the light beam propagation direction (second direction Y axis), that is, the size is reduced by 0.2 mm, so that the camera module 1 can reduce the wall thickness of the housing 11 on one side in the horizontal direction (third direction X axis) and the longitudinal direction of the light beam propagation direction (second direction Y axis).
[0149] Compared with the bracket made by the metal material forming process, the bracket 12 formed by injection molding has a smaller thickness. For example, the thickness of the bracket made by the metal material forming process is about 0.5 mm, while the thickness of the bracket 12 formed by injection molding is about 0.35 mm. In this way, the single-side dimensions of the lateral direction (the third direction X-axis) and the longitudinal direction of the beam propagation direction (the second direction Y-axis) are further saved by about 0.15 mm.
[0150] Therefore, combined with the integrated design and embedded molding process, the shell 10 of the present application saves about 0.35mm in single-side dimension in the horizontal direction (third direction X-axis) and the longitudinal direction of light beam propagation (second direction Y-axis), thereby further reducing the size of the camera module 1 of the present application.
[0151] The above data is only used to illustrate the advantages of the integrated design and embedded molding process adopted by the shell 10 of the present application. Depending on the design of the camera module 1, the size that can be saved is different. More size can be saved, or less size can be saved. However, on the basis of the integrated design, the wall thickness of the shell of the prior art can be at least reduced, and a portion of the wall thickness of the bracket 12 can be further saved.
[0152] In addition, the bracket 12 of the housing 10 obtained by the insert molding process is embedded in a part of the outer shell 11, so that even if the wall thickness of the bracket 12 is reduced, its strength can be guaranteed.
[0153] Next, the formation method of the aforementioned separation space 108 is described in detail.
[0154] The main body 1001 and the tail 1002 are connected to form a separation space 108 suitable for accommodating the photosensitive component 40 in the semi-finished camera module 70.
[0155] In one embodiment of the present application, the housing 11 is formed on one side of the first side wall portion 121, the second side wall portion 122 and the third side wall portion 123 along the height direction (first direction Z axis). There is a spacing space 108 between the fourth side wall portion 124 and the housing 11. The spacing space 108 is formed between the light outlet 105 and the fourth side wall portion 124, surrounded and defined by a portion of the first side wall portion 121, the fourth side wall portion 124 and a portion of the third side wall portion 123, and formed on the side of the housing 11. After the camera module 1 is assembled, the photosensitive component 40 is accommodated in the spacing space 108.
[0156] Specifically, taking the camera module 1 as a periscope camera module as an example, the light port 202 is located at the exit side of the lens assembly 30, and the photosensitive component 40 is installed on one side of the light port 202, so that the light beam can reach the photosensitive component 40 for imaging after passing through the lens assembly 30. The photosensitive component 40 and the base 20 are fixed to remain on one side of the light port 202. After the housing 10 is installed outside the base 20, the bracket 12 is sleeved on the outside of the photosensitive component 40.
[0157] Furthermore, the end of the base 20 defines an installation space 203 for installing the photosensitive component 40, and the light port 202 is located between the receiving space 200 and the installation space 203. In this embodiment of the housing 10, the photosensitive component 40 is installed in the installation space 203, and after being fixed to the base 20, the housing 10 is installed outside the base 20, and the housing 10 surrounds the base 20 and the photosensitive component 40. Among them, the shell 11 of the housing 10 covers the receiving space 200, and the photosensitive component 40 located in the installation space 203 can be exposed through the spacing space 108 to avoid interference between the installation of the housing 10 and the photosensitive component 40.
[0158] Furthermore, a mounting seat 204 is provided at the rear end of the base 20 along the optical path direction, and the light opening 202 is provided on the mounting seat 204, that is, the mounting seat 204 is located between the receiving space 200 and the installation space 203, and divides the shell covering space 1000 into the main space 1100 and the receiving space 1200. During assembly, the main space 1100 corresponds to the receiving space 200, forming a space that is closed to the internal structure on the base 20, and the receiving space 1200 corresponds to the installation space 203, forming a space suitable for installing the photosensitive component 40.
[0159] like Figure 3-4 As shown, the mounting base 204 is perpendicular to the bottom surface of the base 20 and the direction of light beam propagation, and the light incident side thereof and the main body 1001 of the shell 10 together form a closed space from the light inlet 104 to the light outlet 105, so as to isolate the internal structure of the camera module 1 placed in the receiving space 200 from the physical contact with the outside world, and avoid the entry of debris and dust into the receiving space 200 during the subsequent processing of assembly and welding, causing the risk of stains and affecting the imaging of the camera module 1; the photosensitive component 40 is installed on the light outlet side of the mounting base 204, so that the assembly process in the two spaces can be carried out synchronously, further simplifying the assembly steps of the camera module 1.
[0160] Among them, the photosensitive component 40 includes a photosensitive chip, a circuit board 41, a connecting belt 42 and a connector 43. The photosensitive chip is connected to the circuit board 41 in a circuit, the connecting belt 42 extends from the circuit board 41, and the connector 43 is located on one side of the connecting belt 42. The circuit board 41, the connecting belt 42 and the connector 43 are connected in sequence, and the connector 43 and the electronic device can be conductively connected to conduct the camera module 1 and the electronic device. According to the different adaptation requirements of the electronic device, the connecting belt 42 will be configured with different bending methods so that the connector 43 is located in an appropriate position and fixed to the electronic device. For example, but not limited to, the connecting belt 42 is bent 90° relative to the circuit board 41, so that the connector 43 is located on the side of the camera module 1, that is, located on one side of the camera module 1 in the horizontal direction (third direction X-axis), or located on one side of the camera module 1 in the height direction (first direction Z-axis); the connecting belt 42 is bent 180° relative to the circuit board 41, and the connector 43 is located on one side of the camera module 1 in the longitudinal direction of the light beam propagation direction (second direction Y-axis).
[0161] Depending on the different orientations of the connector 43 relative to the bracket 12, different installation methods of the housing 10 need to be considered to avoid interference with the connector 43. When the connector 43 is located below the bracket 12, the connecting belt 42 extends from the bottom of the bracket 12, so that the connector 43 is closer to the electronic device than the bracket 12, and the housing 10 is installed from top to bottom to the outside of the base 20 and the photosensitive component 40 without interference with the connector 43. When the connector 43 is located above the bracket 12, the connecting belt 42 extends from the top of the bracket 12, and the housing 10 is installed from top to bottom to the outside of the base 20 and the photosensitive component 40, it is necessary to consider avoiding interference between the housing 10 and the connector 43.
[0162] It is understandable that both the upper and lower sides of the photosensitive component 40 along the height direction (first direction Z axis) can be exposed through the spacing space 108, so that the connection belt 42 can be connected at both the upper and lower sides. In the embodiment where the connector 43 is located on one side of the longitudinal direction (second direction Y axis) of the camera module 1 that is not the light beam propagation direction, the connection belt 42 can be connected from the bottom to avoid interference with the assembly of the housing 10.
[0163] In one embodiment of the present application, the aforementioned separation space 108 exists between the outer shell 11 and the fourth side wall portion 124 , and the outer shell 11 is formed on the top of the first side wall portion 121 , the second side wall portion 122 and the third side wall portion 123 .
[0164] In some examples, the aforementioned partition space 108 exists between the housing 11 and the tail portion 1002, and the partition space 108 is connected to the accommodating space 1200 of the tail portion 1002 and the installation space 203 on the base 20, forming an installation cavity for the photosensitive component 40 on the camera module 1. The photosensitive component 40 is installed on the light-emitting side of the mounting seat 204, and the tail end of the connecting belt 42 thereof extends from the partition space 108 to connect the camera module 1 and the electronic device.
[0165] In another embodiment of the present application, the housing 11 is formed on the top of the first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124, and the aforementioned spacing space 108 does not exist between the housing 11 and the fourth side wall portion 124. The housing 11 integrally covers the receiving space 200 and the installation space 203 of the base 20, and the connecting belt 42 of the photosensitive component 40 can be connected from the direction opposite to the housing 11 along the height direction (first direction Z axis), that is, from the bottom, so that the connector 43 is located at the bottom and does not interfere with the assembly of the housing 10.
[0166] Among them, the attachment position of the connecting belt 42 after positioning the connector 43 after adopting the housing 10 of the present application is specifically introduced. In some examples, the connecting belt 42 is attached between the fourth side wall portion 124 of the bracket 12 and the photosensitive component 40, or in other words, the connecting belt 42 is fixed on the back of the photosensitive component 40. The connector 43 is led out from the inner side of the fourth side wall portion 124 above or below the height direction (first direction Z axis). In some examples, the connecting belt 42 is attached between the first side wall portion 121 or the third side wall portion 123 of the bracket 12 and the base 20, and the connector 43 can be led out from the inner side of the first side wall portion 121 or the third side wall portion 123 below the height direction (first direction Z axis). In other examples, the connecting belt 42 can be attached to the bottom of the camera module 1 so that the connector 43 is located at the bottom of the camera module 1.
[0167] As mentioned above, the shell 10 has an installation opening, and the shell 10 defines a shell covering space 1000. The shell covering space 1000 is connected to the external space through the installation opening. The shell 10 covers the base 20 through the installation opening, and the base 20 is accommodated in the shell covering space 1000.
[0168] In one embodiment of the present application, the mounting opening is surrounded and defined by the bracket 12. Specifically, the bracket 12 defines the lower end of the housing 10 (i.e., the end close to the mainboard of the electronic device), and the shell 11 defines the upper end of the housing 10 (i.e., the end close to the light hole of the electronic device). The shell 11 extends from the upper end of the housing 10 to the bracket 12, and the bracket 12 continues to verify and define the lower end of the housing 10.
[0169] In another embodiment of the present application, the installation opening is surrounded and defined by the end of the shell 11. The shell 11 extends integrally from the upper end of the housing 10 to the lower end of the housing 10, and the bracket 12 surrounds the shell 11 and is formed outside the shell 11.
[0170] In another embodiment of the present application, the mounting opening is defined by the bracket 12 and the housing 11. A portion of the housing 11 extends integrally from the upper end of the housing 10 to the lower end of the housing 10, and another portion extends to the bracket 12, and then continues to extend from the bracket 12 to the lower end of the housing 10.
[0171] In the housing 10 , the thickness of the portion formed by the shell 11 does not exceed the thickness of the portion formed by the bracket 12 . Furthermore, the thickness of the portion formed by the shell 11 is much smaller than the thickness of the portion formed by the bracket 12 .
[0172] The housing 10 is provided with a hollow area 13, and the hollow area 13 is located at the bracket 12, so that the bracket 12 is partially hollowed out, the wall thickness of a part of the housing 10 is reduced, and the weight of the housing 10 is reduced. The hollow area 13 can be provided by hollowing out a part of the housing 10, or by reducing the wall thickness of a part of the housing 10, but still retaining a part of the wall thickness. Further, the hollow area 13 is provided at the side wall portion 102.
[0173] In some examples of the present application, the shell 10 is also provided with a positioning area 14, which is suitable for cooperating with a corresponding structure of the base 20, such as a matching structure 205, to assist in installing the shell 10 to the base 20. The positioning area 14 can be opened in the shell 11 and / or the bracket 12, and is located at the side wall portion 102 of the shell 10. Further, it is located at the end of the side wall portion 102 so as to cooperate with the matching structure 205 of the base 20. Among them, the positioning area 14 can be implemented as an avoidance space, and the matching structure 205 can be implemented as a boss structure so that the two can cooperate with each other. Further, the positioning area 14 can be set in the hollow area 13, and the matching structure 205 can be a boss set for the hollow area 13.
[0174] In order to further simplify the assembly steps of the camera module 1, a groove-shaped connection area 15 is provided on the bracket 12 to expose the connection area between the pins of the circuit component 60 and the circuit board 41 of the photosensitive component 40. Figure 6 , Fig. 9 and Fig.10 As shown, the connection area 15 is formed on the bracket 12 near the photosensitive component 40 to cooperate with the welding of the pin and the circuit board 41. It can be understood that the connection area 15 is set on the bracket 12 corresponding to the projection area of the installation space 203.
[0175] Among them, among the four shell side walls that constitute the bracket 12, the first side wall portion 121 and the third side wall portion 123 are the positions for fixing the camera module 1 by glue, the second side wall portion 122 is suitable for positioning the prism, and the fourth side wall portion 124 corresponds to the assembly of the photosensitive component 40. Combined with the functions of each shell side wall, the connecting area 15 is preferably arranged on the first side wall portion 121 and / or the third side wall portion 123 to reduce the glue area on the two shell side walls of the bracket 12, reduce the mass and glue amount of the bracket 12, thereby reducing the deformation of the internal structure of the module caused by excessive glue area, especially the bending of the position and path of the lens and focus motor, and further avoiding the eccentricity problem of the camera module 1.
[0176] Specifically, the connection area 15 is arranged on the rear side of the first side wall portion 121 along the direction of the optical path and on the rear side of the third side wall portion 123 along the direction of the optical path. In some examples, the connection area 15 is arranged between the main body portion 1001 and the rear portion 1002 to accommodate the layout of the circuit component 60 embedded in the outer side surface of the base 20 and the assembly orientation of the photosensitive component 40 on the camera module 1, and to expose the connection area between the pin and the circuit board 41 to avoid the two.
[0177] More specifically, a pair of notches are provided at the connection between the main body bracket and the tail bracket. A portion of the tail side of the main body bracket along the light beam propagation direction extends in the opposite direction to form a first notch 151, and a portion of the head side of the tail bracket along the light path direction continues to extend along the light beam propagation direction to form a second notch 152. The first notch 151 and the second notch 152 are arranged opposite to each other and enclose a groove, i.e., forming the connection area 15, which is used to expose the connection area between the pins of the circuit component 60 of the camera module 1 and the circuit board 41 of the photosensitive component 40.
[0178] Furthermore, any side of the connection area 15 does not contact the shell 11 and its junction with the bracket 12, and avoids the area of thickness H1 as much as possible to prevent the processing and forming of the connection area 15 or the welding operation performed in the connection area 15 from causing the shell 11 to deform and affecting the mechanical strength of the shell 10.
[0179] Attach Figure 6-7 From the perspective of , the housing 11 has the partition space 108, and the connecting belt 42 extends outward from the partition space 108 to connect the camera module 1 and the electronic device. In some embodiments, the partition space 108 is formed between the tail end of the housing 11 portion of the main body 1001 along the optical path and the top of the tail 1002, that is, the tail 1002 is formed only by the bracket 12, and does not have the housing 11.
[0180] In some embodiments of the present application, the first notch 151 at the bottom is located at the bottom of the embedded portion 10011 of the main body 1001, and the second notch 152 is located at the bottom of the nested portion 10021 of the tail portion 1002, that is, the embedded portion 10011 and the nested portion 10021 separate the spacing space 108 and the connecting area 15, thereby preventing the mechanical strength of the bracket 12 from being affected due to too large a space occupation after the connection, and preventing the bracket 12 from being deformed due to external force during the assembly process. At the same time, the nested connection between the embedded portion 10011 and the nested portion 10021 further enhances the structural strength of the connecting area 15.
[0181] Among them, the size of the notch has a certain influence on the structural strength of the corresponding opening sides on the main body 1001 and the tail 1002. From the perspective of the drawings in the specification, the first notch 151 and the second notch 152 are preferably notches with a larger length in the height direction (first direction Z axis), enclosing a groove with a larger length in the height direction (first direction Z axis), that is, the connecting area 15 with a larger length in the height direction (first direction Z axis).
[0182] Furthermore, the connection area 15 is formed by a notch and a side edge, that is, the first notch 151 on the main body 1001 is enclosed by the side edge of the tail 1002, or the second notch 152 of the tail 1002 is enclosed by the side edge of the main body 1001, to form the connection area 15.
[0183] In some examples, the embedded portion 10011 and the nested portion 10021 are welded after being nested and connected, which further enhances the connection strength between the main body portion 1001 and the tail portion 1002 and improves the structural strength of the shell 10 and the connection area 15 .
[0184] Preferably, the height of the connection area 15 in the height direction (first direction Z axis) does not exceed half of the height of the bracket 12 in the height direction (first direction Z axis) so as to reduce the influence of the opening of the groove on the bracket 12 on the connection strength between the main body 1001 and the tail 1002 and the structural strength of the shell 10.
[0185] In another specific embodiment of the present application, the housing 11 does not have the spacing space 108, and the connecting belt 42 extends from the gap between the bracket 12 and the base 20 to connect the camera module 1 and the electronic device.
[0186] like Figure 7-10 As shown, the connection area 15 is provided on the bracket 12. When the height of the connection area 15 in the height direction (first direction Z axis) is not less than the height of the bracket 12 in the height direction (first direction Z axis), the mounting structure 103 is arranged on the bracket 12 away from the connection area 15 to avoid the two being too close to each other and interfering with each other during the welding and positioning and fixing operations.
[0187] In some examples of the present application, the bracket 12 of the main body 1001 has at least three mounting structures 103, which are respectively located on the first side wall 121, the second side wall 122 and the third side wall 123, to position the three sides of the main body 1001, and the tail portion 1002 has at least one mounting structure 103, which cooperates with the nested connection between the tail portion 1002 and the main body 1001 to determine the assembly positioning of the tail portion 1002.
[0188] In some examples, the number of the connection area 15 is one, and at least two of the mounting structures 103 are respectively arranged at the two end points of the diagonal of the bracket 12. When the connection area 15 is located at the tail of the first side wall portion 121 close to the fourth side wall portion 124, one of the mounting structures 103 is arranged at the junction or connecting corner of the first side wall portion 121 and the second side wall portion 122, and the other is arranged at the junction or connecting corner of the third side wall portion 123 and the fourth side wall portion 124; when the connection area 15 is located at the tail of the third side wall portion 123 close to the fourth side wall portion 124, one of the mounting structures 103 is arranged at the junction or connecting corner of the second side wall portion 122 and the third side wall portion 123, and the other is arranged at the junction or connecting corner of the first side wall portion 121 and the fourth side wall portion 124.
[0189] In some examples, there are two connecting areas 15, which are located at the tail of the second side wall portion 122 close to the fourth side wall portion 124 and the tail of the third side wall portion 123 close to the fourth side wall portion 124, respectively. At least two of the mounting structures 103 are symmetrically arranged on the first side wall portion 121 and the third side wall portion 123, and at least one of the mounting structures 103 is arranged on the first side wall portion 121 to avoid mutual interference between the mounting structure 103 and the connecting area 15, so as to ensure the mechanical strength of the bracket 12 and the installation stability of the camera module 1 on the electronic device.
[0190] In one embodiment of the present application, the main body 1001 and the tail portion 1002 jointly enclose the connection area 15, and the mounting structure 103 located near the connection between the main body 1001 and the tail portion 1002 and the connection area 15 are not located in the same height direction (first direction Z axis), so as to avoid the fixing operation on the mounting structure 103 affecting the connection strength between the main body 1001 and the tail portion 1002.
[0191] When the height of the connection area 15 in the height direction (first direction Z axis) is less than half of the height of the bracket 12 in the height direction (first direction Z axis), the size of the connection area 15 is relatively small, and the mounting structure 103 and the connection area 15 can be implemented as being arranged in sequence along the height direction (first direction Z axis) of the bracket 12 to simplify the welding positioning within the connection area and the fixed positioning of the shell 10.
[0192] In some examples of the present application, the mounting structure 103, the connection area 15 and the nested connection between the main body 1001 and the tail 1002 are located in the same height direction (first direction Z axis), and the mounting structure 103 and the connection area 15 are both located at the bottom of the nested connection, so that the connection strength of the nested connection ensures the structural strength of the connection area 15. From the perspective of the accompanying drawings, the positioning hole 1031 of the mounting structure 103 and the connection area 15 are not located in the same height direction (first direction Z axis) of the bracket 12, which further reduces the influence of the fixing operation on the connection strength and structural strength.
[0193] Among all the mounting structures 103 on the housing 10, at least two of the mounting structures 103 are arranged at different heights in the height direction (first direction Z axis) to determine the positioning of the housing 10 as a whole in the height direction (first direction Z axis). In one embodiment of the present application, at least two of the mounting structures 103 on the main body 1001 are arranged at different heights in the height direction (first direction Z axis) to determine the positioning of the main body 1001 in the height direction (first direction Z axis); and at least one of the mounting structures 103 on the tail 1002 is arranged to determine the positioning of the tail 1002 in the height direction (first direction Z axis).
[0194] Furthermore, when there are at least two mounting structures 103 on the same side wall of the bracket 12, at least two of the mounting structures 103 are set at different heights in the height direction (first direction Z axis) to further determine the positioning of the side wall of the bracket 12 in the height direction (first direction Z axis).
[0195] In some embodiments, at a corner of the bracket 12 or at two corners located on its diagonal line, a mounting structure 103 may be provided on both sides of each corner to determine the positioning of the corner on the side of the bracket 12, further improving the installation stability of the camera module 1 on the electronic device.
[0196] In one embodiment of the present application, the camera module 1 is an upright camera module, including the shell 10 and the base 20, the shell 10 includes the cover portion 101 and the side wall portion 102, the extended distribution planes of which are perpendicular to each other, a portion of the top of the side wall portion 102 and the cover portion 101 together constitute the outer shell 11, and the other portions of the side wall portion 102 constitute the bracket 12, the outer shell 11 has a light opening 202, a portion of the lens assembly 30 extends from the accommodating space 200 between the shell 10 and the base 20 along the opposite direction of the optical path, and extends out of the shell 10 through the light opening 202 of the outer shell 11 to connect the camera module 1 and the electronic device.
[0197] There is a certain gap between the bracket 12 and the photosensitive component 40. In the example where the bracket 12 is sleeved on the outside of the photosensitive component 40, the gap between the bracket 12 and the photosensitive component 40 can prevent the bracket 12 and the photosensitive component 40 from interfering with each other and affecting the photosensitive component 40.
[0198] The lens driving assembly and the optical path turning driving assembly form a driving mechanism of the camera module 1 of the present application, wherein one of the first optical path turning driving unit and the second optical path turning driving unit, and one of the first lens driving unit and the second lens driving unit are electronic components, and the electronic components need to be connected to the circuit.
[0199] The driving mechanism of the camera module 1 also includes a position sensing component, which is used to sense the position of the lens assembly 30 and / or the optical path turning assembly 50 to improve the accuracy of motion position control.

[0200] The camera module 1 also includes a circuit component 60, which connects the electronic component and the photosensitive component 40.

[0203] Since the circuit assembly 60 is embedded in the base 20, the circuit assembly 60 does not need to occupy additional space, and the camera module 1 is smaller in size compared to the form of an independent circuit structure (such as a circuit board). In addition, the circuit connection of the camera module 1 is designed to be embedded, which can protect the circuit structure, avoid the assembly difficulties and reliability problems caused by the exposed independent circuit structure, simplify the assembly process, and improve the reliability of the camera module 1.
