Description

Technical Field

[0001] The present application relates to the field of camera modules, and in particular to camera modules, multi-camera modules, assembly methods and electronic devices thereof. 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.

[0008] At present, the number of camera modules in electronic devices is increasing, usually equipped with multiple cameras, and multiple camera modules are compactly arranged together to achieve better shooting functions. The phase position relationship between multiple camera modules and the setting position in the electronic device need to meet the design requirements of the electronic device to avoid offset and reduce assembly tolerance.

[0009] When two or more camera modules are installed independently, they need to be positioned and installed separately. Since the multiple camera modules are arranged compactly, interference may occur during positioning, affecting the installed camera modules and making it inconvenient to continue positioning and installing new camera modules in a compact space.

[0010] Furthermore, terminal manufacturers currently have an increasing demand for periscope camera modules, and there is a demand for the configuration of dual periscope camera modules. The relative position relationship between the dual periscope camera modules and the position setting requirements in electronic equipment are higher, requiring more precise assembly and reduced assembly tolerance to ensure the imaging effect of the camera module.

[0046] According to the instruction manual Figures 1 to 13 The present application provides a camera module 1, which includes a shell 10 and a semi-finished camera module 70. The semi-finished camera module 70 is installed in the shell 10. The shell 10 includes an integrally formed outer shell 11 and a bracket 12. The bracket 12 has at least two integrally formed bracket parts, at least one of which is integrally formed with the shell 11 to form a covering space 1000 located on at least the outer peripheral side of the semi-finished camera module 70, providing installation positioning and internal structure protection for the semi-finished camera module 70, and at least one of the bracket parts encloses an installation space 2000 for providing installation positioning space for other semi-finished camera modules 70, and the extension direction of at least one of the bracket parts is different from that of at least one of the other bracket parts.

[0047] The camera module semi-finished product 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 the 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 on at least a portion of the outer peripheral side of the base 20 to cover the lens assembly 30 located in the receiving space 200.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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 achieve focus adjustment 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 lens 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.

[0052] 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.

[0053] In other embodiments of the driving form of the present application, the lens driving component is implemented as a piezoelectric motor drive, an SMA (Shape Memory Alloys) drive, a stepper motor or other driving methods.

[0054] 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.

[0055] The types of the camera module 1 include upright camera module 1, periscope camera module 1, other types of telephoto camera modules 1 and other forms.

[0056] In one embodiment of the present application, the camera module 1 is implemented as a periscope camera module 1 as an example for explanation. Figure 1-6As 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.

[0057] 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).

[0058] 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.

[0059] The above example illustrates an instance in which the optical path deflection component 50 is disposed on the incident side of the lens assembly 30. In other periscope camera modules 1, 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.

[0060] In other parts of the periscope camera module 1, 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 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.

[0061] In other periscope camera modules 1, 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 it is incident on the optical path turning component 50.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] The lens driving assembly and the optical path deflection driving assembly may adopt the same driving form or different driving forms.

The extension direction of at least one bracket part is different from that of at least one other bracket part, so as to avoid magnetic interference between the semi-finished camera module 70 installed in the at least two bracket parts, thereby providing an integrated bracket with smaller magnetic interference to control the spatial dimensions of multiple semi-finished camera module 70 during installation.

[0069] More specifically, the first shell area 2001 and the second shell area 2002 are separated by the two integrally formed areas of the bracket parts belonging to these two areas, so as to divide the assembly operation area of ​​the multi-camera module 2 into areas to avoid operational interference between at least two of the camera module semi-finished products 70 and / or at least one of the shells 11 interconnected with the bracket parts during assembly.

[0070] In some embodiments of the present application, the multi-camera module 2 is implemented to include a housing 10 and two camera module semi-finished products 70, such as Figure 4-6 As shown, the two shells 11 are implemented as a first shell 11001 and a second shell 11002, the two bracket parts of the bracket 12 are implemented as an integrally formed first bracket part 121 and a second bracket part 122, and the two camera module semi-finished products 70 are implemented as a first semi-finished product 71 and a second semi-finished product 72.

The second shell 11002 and the second bracket part 122 are split structures, and the two are interconnected and fixed to form the second shell area 2002. The second semi-finished product 72 of the camera module semi-finished product 70 is installed in the second shell area 2002.

[0071] Specifically, each bracket portion of the shell 10 is installed on at least a portion of the outer peripheral side of a semi-finished product 70 of the camera module, the first bracket portion 121 is installed on the first semi-finished product 71, and the second bracket portion 122 is installed on the second semi-finished product 72, so as to ensure the accuracy of the assembly and simplify the assembly process.

[0072] Furthermore, the light inlets 104 of the two camera module semi-finished products 70 are arranged adjacent to each other, such as Figure 4-6As shown, the light entrance port 104 of the first semi-finished product 71 is arranged adjacent to the light entrance port 104 of the second semi-finished product 72, thereby reducing the change in viewing angle and depth perception caused by switching the camera module 1 and avoiding a jump phenomenon when switching the function of the camera module 1.

[0073] In some embodiments of the present application, the two camera module semi-finished products 70 are arranged in a Z shape, such as Figure 4-6 As shown, the light inlet 104 of the first semi-finished product 71 and the light inlet 104 of the second semi-finished product 72 are adjacently arranged in the transverse direction (the third direction X-axis), and the arrangement direction of the first semi-finished product 71 and the arrangement direction of the second semi-finished product 72 both extend along the light beam propagation direction (the second direction Y-axis) but in opposite directions, that is, the light beam propagation direction of the first semi-finished product 71 is parallel to but opposite to the light beam propagation direction of the second semi-finished product 72 to form a Z-shaped arrangement.

[0074] In some optional embodiments, the two camera module semi-finished products 70 are arranged in an L shape, the light inlet 104 of the first semi-finished product 71 and the light inlet 104 of the second semi-finished product 72 are arranged adjacent to each other in the transverse direction (the third direction X-axis), the arrangement direction of the first semi-finished product 71 extends along the light beam propagation direction (the second direction Y-axis), and the arrangement direction of the second semi-finished product 72 extends along the light beam propagation direction (the second direction Y-axis), that is, the light beam propagation direction of the first semi-finished product 71 and the light beam propagation direction of the second semi-finished product 72 are perpendicular to each other to form an L shape arrangement, such as Fig.11 As shown, the first semi-finished product 71 is correspondingly arranged in the first bracket part 121, and the second semi-finished product 72 is correspondingly installed in the second bracket part 122. According to the L-shaped arrangement of the first bracket part 121 and the second bracket part 122, the L-shaped arrangement between the first semi-finished product 71 and the second semi-finished product 72 is determined.

[0075] In some optional embodiments, two of the camera module semi-finished products 70 are arranged side by side in an equal sign arrangement, the light inlet 104 of the first semi-finished product 71 and the light inlet 104 of the second semi-finished product 72 are adjacently arranged in the transverse direction (third direction X axis), and the arrangement direction of the first semi-finished product 71 and the arrangement direction of the second semi-finished product 72 both extend along the light beam propagation direction (second direction Y axis), that is, the light beam propagation direction of the first semi-finished product 71 is parallel to the light beam propagation direction of the second semi-finished product 72, so as to form a side-by-side equal sign arrangement, such as Fig.10 As shown, the first semi-finished product 71 is correspondingly arranged in the first bracket part 121, and the second semi-finished product 72 is correspondingly installed in the second bracket part 122. According to the equal sign parallel arrangement of the first bracket part 121 and the second bracket part 122, the equal sign parallel arrangement between the first semi-finished product 71 and the second semi-finished product 72 is determined.

[0076] Furthermore, the driving components in the two semi-finished camera module 70 are staggered, and the driving components are composed of the lens driving assembly and the optical path turning driving assembly in the semi-finished camera module 70. The arrangement is such that there is a certain distance between the driving components in the two semi-finished camera module 70 to avoid magnetic interference.

[0077] When the two semi-finished products 70 of the camera module are arranged in a Z shape or an L shape, the first semi-finished product 71 is arranged and extended along the light beam propagation direction (the second direction Y axis), and is adjacent to a portion of the second semi-finished product 72 on one side thereof extending along the light beam propagation direction (the second direction Y axis). The driving components of the first semi-finished product 71 and the driving components of the second semi-finished product 72 are alternately arranged to avoid adjacent areas as much as possible to avoid magnetic interference.

[0078] In some optional embodiments, each bracket portion of the shell 10 corresponds to the installation of at least two of the camera module semi-finished products 70, and a partition structure is arranged in the same bracket portion to separate and position the installation of two adjacent camera module semi-finished products 70, so that the installation space 2000 or the covering space 1000 surrounded by a single bracket portion can provide positioning installation and internal structure protection for multiple camera module semi-finished products 70 at the same time.

[0079] Reference Manual Attached Figures 9 to 11 The shell 11 and the bracket 12 of the housing 10 are integrally formed to form one component. That is to say, the housing 10 is an integrally formed component.

[0080] 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 a light entrance 104 is opened on the shell 11; the bracket 12 has at least two integrally formed bracket parts, at least one of which is used to surround at least a part of the circumference of the semi-finished camera module 70, and is integrally formed with the shell 11, and the thickness of the bracket 12 is not less than the thickness of the shell 11, and is suitable for the installation of the camera module 1 and the electronic device, so that the camera module 1 is fixed to the electronic device.

[0081] In an optional embodiment of the present application, the shell 11 of the housing 10 mainly plays a role in controlling stray light and covering the top surface, and the bracket 12 plays a role in peripheral protection. Specifically, the minimum thickness of the bracket 12 is not less than the minimum thickness of the shell 11.

[0082] Furthermore, the minimum thickness of the shell 11 may correspond to a different covered material than the support 12 , and they may be formed based on different processing methods, thereby ensuring that the minimum thickness of the support 12 is not less than the minimum thickness of the shell 11 .

[0083] The shell 10 of the present application adopts an integrated design, integrating the functions of the outer shell and the bracket of the camera module 1 in the prior art, reducing the number of parts, simplifying the assembly process, improving production efficiency, and saving some size, which is conducive to the miniaturization of the camera module 1.

[0084] The unnumbered shells and brackets in the following text refer to the shells and brackets in the prior art, the numbered shells 11 and brackets 12 refer to the shells 11 and brackets 12 in the present application, and the integration of the shells 11 and brackets 12 refers to the integration between the integrally formed shells 11 and a bracket portion of the bracket 12, which is specifically implemented as the integration between the first shell 11001 and the first bracket portion 121.

[0085] In some embodiments of the present application, the housing 10 includes an integrally formed shell 11 and a bracket 12, the bracket 12 having at least two integrally formed bracket parts, wherein at least one of the bracket parts is integrally formed with the shell 11 to form a covering space 1000 installed on at least part of the outer peripheral side of a semi-finished camera module 70, and at least one of the bracket parts of the semi-finished camera module 70 forms an installation space 2000 for installing another semi-finished camera module 70. The extension direction of at least one of the bracket parts is different from that of at least one of the other bracket parts, so as to avoid magnetic interference between the semi-finished camera modules 70 installed in the at least two bracket parts, thereby providing an integrated bracket with smaller magnetic interference to limit the spatial size of multiple semi-finished camera modules 70 when they are installed.

[0086] like Figures 4 to 13 As shown, the shell 11 is implemented as a first shell 11001, and the bracket 12 is implemented as a first bracket part 121 and a second bracket part 122. The first shell 11001 and the first bracket part 121 are integrally formed to form a covering space 1000, covering at least part of the outer peripheral side of the first semi-finished product 71 to provide internal structure protection for the first semi-finished product 71. The first semi-finished product 71 is installed in the covering space 1000, and the second bracket part 122 encloses an installation space 2000 to provide installation positioning for other camera module semi-finished products 70.

[0087] The first bracket portion 121 and the second bracket portion 121 both extend along the light beam propagation direction from the light incident side to the light exit side in the corresponding camera module semi-finished product 70, that is, the light beam propagation direction in the camera module semi-finished product 70 corresponding to the covering space 1000 or the installation space 2000 is used as the extension direction. The extension directions of the first bracket portion 121 and the second bracket portion 122 are inconsistent, thereby providing an integrated bracket with smaller magnetic interference for at least two of the corresponding camera module semi-finished products 70 and limiting the installation size of at least two of the camera module semi-finished products 70.

[0088] In some embodiments of the present application, the arrangement direction of the first bracket portion 121 and the arrangement direction of the second bracket portion 122 are parallel to or perpendicular to each other. Figures 7 to 11 As shown, the first bracket portion 121 and the second bracket portion 122 are arranged in a Z shape, in parallel with equal signs, or in an L shape to accommodate rapid positioning and assembly of different camera module semi-finished products 70 in different bracket portions.

[0089] In one embodiment of the production and manufacturing of the shell 10 of the present application, the shell 11 and the bracket 12 of the shell 10 are integrally formed, that is, the shell 11 and the bracket 12 are integrally formed using the same material, wherein the material may be a high-strength plastic material or a metal material.

[0090] In one embodiment of the production and manufacturing of the shell 10 of the present application, the shell 11 and the bracket 12 are made of the same metal material, and the shell 10 is formed in one piece using a metal material molding process. Among them, the molding processes that can be used include but are not limited to integrated die casting, metal casting, metal forging, metal stamping, powder metallurgy, metal injection molding (MIM, Metal Injection Molding), stretching, secondary stretching, etc. Among them, the metal materials that can be used include but are 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 is not limited to stainless steel, SPCC (Steel Plate Cold Commercial, cold-rolled carbon steel sheet), etc.

[0091] In an optional embodiment of the present application, the housing 11 and the bracket 12 are made of aluminum alloy material, and the housing 10 is formed in one piece by aluminum alloy integrated die-casting. Aluminum alloy integrated die-casting, such as aluminum-magnesium alloy, is used to achieve a weight reduction effect by utilizing the lightweight characteristics of the material, thereby reducing the weight of the housing 10 and the camera module 1. In addition, aluminum alloy materials have good comprehensive properties, high strength and good toughness. The housing 10 produced thereby has good mechanical strength, which is beneficial to improving the reliability of the housing 10 and the camera module 1. The use of an integrated design allows the same part to integrate multiple functions, improves the functionality and integration of components, and also reduces machining and assembly steps, thereby reducing production costs.

[0092] Among them, the wall thickness of the traditional shell 11 is about 0.2 mm. In the present application, the shell 11 and the bracket 12 are integrally formed. In the horizontal and vertical directions of the camera module 1, the wall thickness of the shell 11 can be saved on one side, that is, the size is reduced by 0.2 mm. The horizontal and vertical dimensions of the camera module 1 are reduced, and more design space can also be provided when components such as motors and lenses become further larger.

[0093] The above data is only used to illustrate the advantages of the integrated design adopted by the shell 10 of the present application, that is, the advantages of the integrated design of the first shell 11001 and the first bracket part 121. 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 may be saved. However, on the basis of the integrated design, the wall thickness of the shell in the prior art can at least be reduced.

[0094] In addition, integrated die-casting technology can manufacture parts with complex shapes and fine details; it can accurately control the size of parts, reduce the need for subsequent processing, thereby improving dimensional accuracy; and it can mold multiple parts at one time, improving production efficiency.

[0095] In other examples of the present application, other materials such as zinc alloy, magnesium alloy, tin-based alloy, copper alloy, etc. may also be used for integrated die-casting to manufacture the shell 10 of the present application.

[0096] In one embodiment of the manufacturing of the housing 10 of the present application, the housing 11 and the bracket 12 can be made of different metal materials, and the different metal materials are combined together to form the housing 10 in an integral manner. Among them, the metal materials that can be used include but are not limited to steel-containing materials, aluminum alloys, phosphor bronze, titanium alloys, iron-based materials, etc. Further, the appropriate metal material can be selected based on the comprehensive cost, light weight, mechanical strength, corrosion resistance, etc.

[0097] Taking the case where the housing 11 is made of stainless steel and the bracket 12 is made of aluminum alloy as an example, the stainless steel and aluminum alloy can be integrally formed by a casting process. For example, a suitable mold is designed, and then the two metals are poured into the mold in a certain proportion and order, and the metals are melted at high temperature, and an integral part is formed after cooling. Alternatively, the stainless steel and the aluminum alloy are connected together using welding technology, and welding technologies such as argon arc welding or laser welding can be used to ensure the strength and quality of the welding. Alternatively, the housing 11 made of stainless steel is first formed by stamping, and when the aluminum alloy of the bracket 12 is cast, the housing 11 can be placed in the mold as a stainless steel insert, and then cast to form a mechanical or metallurgical bond between the aluminum alloy and the stainless steel to obtain the housing 10.

[0098] The above content introduces an embodiment of using metal material to integrally form the housing 10. In other embodiments of the present application, the housing 10 may be integrally formed using non-metal material.

[0099] 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.

[0100] Next, the structure of the housing 10 of the present application is described in detail.

[0101] The housing 10 includes a cover portion 101 and a side wall portion 102, wherein the cover portion 101 is suitable for covering at least a portion of the internal structure of the semi-finished camera module 70, and the side wall portion 102 is suitable for surrounding at least a portion of the circumference of the base 20 and is provided with the light inlet 104, wherein, from the perspective of the accompanying drawings, the cover portion 101 is distributed along the plane where the diameter of the light inlet 104 is located or approximately along the plane where the diameter of the light inlet 104 is located, that is, it extends in the horizontal direction, and at least a portion of the side wall portion 102 is bent from the outer periphery of the cover portion 101 and extends and distributed along the height direction (first direction Z axis) or approximately along the height direction (first direction Z axis). Refer to the attached Figure 1-7 It can be understood that at least part of the side wall portion 102 surrounds the outer side of the base 20, and the cover portion 101 is the top surface of the shell 10 that is located on or approximately on the plane where the diameter of the light entrance 104 is located, covering the top opening formed by the base 20 and at least part of the side wall portion 102.

[0102] The cover portion 101 and at least part of the side wall portion 102 jointly define a covering space 1000 of the housing 10. The housing 10 also has an installation opening 100. The covering space 1000 is connected to the external space through the installation opening 100. The housing 10 covers the base 20 through the installation opening 100, and the base 20 is accommodated in the covering space 1000. The installation opening 100 is surrounded and defined by the first bracket portion 121 of the bracket 12. Specifically, in the height direction (first direction Z axis), the first bracket portion 121 of the bracket 12 defines the lower end of the housing 10 (i.e., the end close to the mainboard side of the electronic device), and the first shell 11001 of the housing 11 defines the upper end of the housing 10 (i.e., the end close to the light through hole side of the electronic device). The first shell 11001 of the housing 11 extends from the upper end of the shell body 10 to the first bracket portion 121 of the bracket 12 , and the lower end of the shell body 10 is further verified and defined by the first bracket portion 121 of the bracket 12 .

[0103] 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 direction (third direction X axis) or along the longitudinal direction (second direction Y axis), and the thickness H1 is less 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 1. In some optional embodiments, 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 1, its thickness size 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. In some optional embodiments, the thickness H1 is implemented as the minimum thickness of the cover portion 101, and the thickness H2 is implemented as the minimum thickness of the side wall portion 102.

[0104] 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 with the lower end surface of the base 20, so as to facilitate the positioning 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.

[0105] refer to Figure 7 As shown, the shell 10 has a shell 11 and a bracket 12, the shell 11 is implemented as a first shell 11001, and the bracket 12 is implemented as an integrally formed first bracket portion 121 and a second bracket portion 122, the first shell 11001 and the first bracket portion 121 are integrally formed, wherein the first bracket portion 121 and the second bracket portion 122 form the side wall portion 102 of the shell, and the portion of the first shell 11001 that is not overlapped and combined with the first bracket portion 121 forms the cover portion 101 of the shell 10.

[0106] In some specific embodiments of the present application, the side wall portion 102 is provided with a positioning structure 103. Specifically, the positioning structure 103 is arranged on the outside of the bracket 12, suitable for the camera module 1 to be installed on the electronic device, and / or suitable for fixing the camera module 1 and other camera modules 1 to form a multi-camera module 2.

[0107] The cover portion 101 , the side wall portion 102 and the positioning structure 103 are formed in one piece by a metal material forming process, so as to integrate the functions of the housing 11 and the bracket 12 .

[0108] 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 1, that is, the 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 a multi-camera module 2 can also be designed in an integrated manner.

[0109] In some embodiments of the multi-camera module 2, the shell 11 of the shell 10 is implemented as the first shell 11001, and the bracket 12 of the shell 10 has more than two integrally formed bracket parts, at least one of the bracket parts is integrally formed with the first shell 11001, and the other bracket parts are interconnected or integrally formed with other shells 11 to form a multi-camera module 2, thereby simplifying the installation and positioning of multiple camera module semi-finished products 70 during the assembly process of the multi-camera module 2.

[0110] In some embodiments of the multi-camera module 2, at least one bracket portion of the bracket 12 is integrally formed with the first shell 11001 to form the covering space 1000, covering at least two of the camera module semi-finished products 70, and a partition structure for separating two adjacent camera module semi-finished products 70 is provided in the bracket portion. Furthermore, the light entrance ports 104 of two adjacent camera module semi-finished products 70 located in the same bracket portion are arranged adjacent to each other, and the driving components are arranged alternately.

[0111] In some embodiments of the present application, the positioning structure 103 includes a positioning portion and a positioning hole, the positioning portion is formed by protruding outward from the outer surface of the side wall portion 102, and the positioning hole is opened in the positioning portion to form a through hole. The positioning hole 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 can be aligned with the positioning hole of the bracket 12 of other camera modules 1 and fixed, so that the camera module 1 is connected to other camera modules 1.

[0112] In other examples, the positioning structure 103 can also be a buckle structure, and the electronic device is positioned and fixed by buckle 205. In other examples, the corresponding positions of the camera module 1 and the electronic device can be buckled and fixed by glue. In other examples, other suitable fixing methods can also be implemented.

[0113] In the embodiment where the housing 10 has at least two bracket parts, the bracket parts enclosing the installation space 2000 are provided with positioning structures 103, such as Figure 7-11 As shown, a positioning structure 103 is provided on the second bracket portion 122 that encloses the installation space 2000. When the first bracket portion 121 of the shell 10 is installed to the first semi-finished product 71, the second bracket portion 122 is fixed by the positioning structure 103 to provide precise installation positioning for the subsequent second semi-finished product 72.

[0114] In some optional embodiments, a positioning structure 103 is provided on the bracket portion that forms the covering space 1000 and the bracket portion that encloses the installation space 2000, that is, the first bracket portion 121 and the second bracket portion 122 are both provided with a positioning structure 103. During the assembly process of the shell 10, the positions of the first bracket portion 121 and the second bracket portion 122 are fixed by the positioning structure 103. The first shell 11001 and the first bracket portion 121 of the shell 10 are installed to at least part of the outer peripheral side of the first semi-finished product 71, and the second bracket portion 122 encloses an installation space 2000 for installing other semi-finished products 70 of the camera module.

[0115] Since the housing 10 is made of metal material, if the camera module 1 is fixed to the electronic device by using a fixing member and a positioning hole, the metal material and the fixing member are not prone to friction and chips when they are matched, thus avoiding the generation of foreign matter.

[0116] The housing 10 also has a light inlet 104, and the incident light beam enters the interior of the camera module 1 and / or the camera module semi-finished product 70 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, reaches the photosensitive component 40, and forms an image 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 transmission routes of the light inlet 104 and the light outlet 105. 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.

[0117] 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.

[0118] The inner surface 106 is defined by the inner surface of the housing 11 and the inner surface of the first bracket portion 121 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 .

[0119] 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.

[0120] Next, the specific structures of the shell 11 and the bracket 12 included in the housing 10 are further described.

[0121] The housing 11 includes a housing cover wall 111, which forms the aforementioned cover portion 101 and is suitable for covering the receiving space 200 of the base 20. The light inlet 104 is opened in the housing cover wall 111, facing the direction of light incidence.

[0122] In one embodiment of the present application, the housing 11 further includes a housing side wall 112, and the housing side wall 112 is disposed around the housing cover wall 111. Specifically, the housing cover wall 111 extends along the plane where the diameter of the light entrance 104 is located, or is roughly distributed along the plane where the diameter of the light entrance 104 is located, and the housing side wall 112 is bent from the outer periphery of the housing cover wall 111 and extends along the height direction (first direction Z axis).

[0123] The bracket 12 and the housing 11 are stacked along the height direction (the first direction Z axis). Specifically, at least a portion of the housing side wall 112 extends toward the bracket 12 and is coupled to the bracket 12 .

[0124] Furthermore, the bracket 12 and the shell side wall 112 are stacked in the height direction so as not to overlap with the shell side wall 112, thereby avoiding increasing the thickness of the shell side wall 112 at the bracket 12, that is, the thickness of the shell side wall 112 is not increased within the length range in the height direction covered by the bracket 12.

[0125] In order to ensure that the bracket 12 and the shell side wall 112 of the shell 11 are stacked and non-overlapping along the height direction (first direction Z axis), the connection between the bracket 12 and the shell 11 is formed between the top of the bracket 12 and the bottom of the shell side wall 112 of the shell 11, wherein the top of the bracket 12 faces the side of the shell cover wall 111. A bending portion 113 is formed between the shell cover wall 111 and the shell side wall 112, and the thickness of the shell cover wall 111 and the shell 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 shell 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 shell 10, which is conducive to reducing the weight of the shell 10.

[0126] 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 stacked housing side wall 112 of the housing 11 is omitted at the bracket 12.

[0127] Therefore, when the shell 11 and the bracket 12 are integrally formed to form the housing 10, the overlapping portion of the bracket 12 and the shell 11 can save the thickness of 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. Furthermore, 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 saves the process of assembling the bracket 12 to the shell 11, and also saves the glue between the bracket 12 and the shell 11.

[0128] 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 and / or longitudinal size; 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 deformation.

[0129] 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, after the bracket 12 and the electronic device are fixed, the connection structure between the bracket 12 and the housing 11 fails, the camera module 1 may become loose or displaced, resulting in a degradation in 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 12 and the housing 11 is omitted, which can reduce the risk points of the camera module 1 and improve the reliability of the camera module 1.

[0130] Furthermore, the glue between the bracket 12 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 painting 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 12 and the housing 11 can save production, assembly and other processes and engineering, improve the production efficiency and production yield of the camera module 1, and can improve the appearance yield of the camera module 1.

[0131] In addition, in the camera module 1 of the prior art, the glue will be pulled due to the shrinkage rate after curing, and the shell 11 is relatively thin, which will cause the shell 11 to be pulled and deformed. The shell 11 is arranged on the outside of the base 20. The shell 11 is pulled and deformed, which may cause the base 20 to be deformed by force, thereby affecting the shape of the receiving space 200 of the base 20, and the position and / or shape of the components located in the receiving space 200, etc., affecting the performance and reliability of the camera module 1. Therefore, after avoiding the glue between the bracket 12 and the shell 11, the deformation problem caused by the shrinkage of the glue curing is also avoided, reducing the assembly tolerance, which is conducive to improving the yield rate of the finished product.

[0132] 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 1 caused by the bracket assembly in the prior art.

[0133] Specifically, in the camera module 1 of the prior art, there is an assembly gap between the bracket 12 and the housing 11, which will cause the housing 11, together with the base 20 of the camera module 1 and its internal structure, to be offset in the bracket 12, so that the light hole provided on the housing 11 is offset relative to the bracket 12. Therefore, when the bracket 12 is assembled to the housing 11, the light hole of the camera module 1 may have been offset. After the camera module 1 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 1 to be offset, resulting in the eccentricity problem of the camera module 1. In addition, the glue between the bracket 12 and the housing 11 will also affect the relative position between the bracket 12 and the housing 11, aggravating the offset problem between the light hole and the bracket 12, making the final light hole of the electronic device and the light hole of the camera module 1 offset more seriously.

[0134] The shell 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 1 of the prior art. In other words, the relative position between the light inlet 104 of the shell 10 and the positioning 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 positioning 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 and 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 positioning 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.

[0135] It is understandable that, according to the design requirements of the camera module 1, the housing 10 and the shell 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, extended service life, etc. For example, surface treatments such as laser engraving, black coating, etc. may be performed on specific areas of the surface of the shell cover wall 111 to improve stray light.

[0136] 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 to ensure the accurate relative position with other components, thereby ensuring 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 to 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.

[0137] In some examples, the bracket 12 is formed by surrounding the outer periphery of the semi-finished camera module 70 for one week, and includes a first side wall portion 12001, a second side wall portion 12002, a third side wall portion 12003 and a fourth side wall portion 12004 located on different sides. The first side wall portion 12001, the second side wall portion 12002, the third side wall portion 12003 and the fourth side wall portion 12004 surround the semi-finished camera module 70 for one week and enclose to form the bracket 12. From the perspective of the accompanying drawings of the specification, the first side wall portion 12001 and the third side wall portion 12003 are distributed along the longitudinal direction (the second direction Y-axis) and are opposite in the transverse direction (the third direction X-axis). The second side wall portion 12002 and the fourth side wall portion 12004 are distributed along the transverse direction (the third direction X-axis) and are opposite in the longitudinal direction (the second direction Y-axis) of the light beam propagation direction. The fourth side wall portion 12004 is located on the light-emitting side of the camera module 1. The first side wall portion 12001, the second side wall portion 12002, the third side wall portion 12003 and the fourth side wall portion 12004 respectively have heights extending and distributed along the height direction (the first direction Z-axis), and jointly enclose to form the bracket 12.

[0138] 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.

[0139] 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 provided 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.

[0140] The shape of the bracket 12 can be frame type, L type, U type, "mouth" type, etc.

[0141] Further, the bracket 12 has at least two integrally formed bracket parts, and the extension directions of the at least two bracket parts are different. Each bracket part is formed around at least one peripheral edge of the camera module semi-finished product 70, and includes a first side wall part 12001, a second side wall part 12002, a third side wall part 12003 and a fourth side wall part 12004 located on different sides, such as Figure 7-11 As shown, the first bracket portion 121 and the second bracket portion 122 both have a first side wall portion 12001, a second side wall portion 12002, a third side wall portion 12003 and a fourth side wall portion 12004 located on different sides, wherein the side wall portion of the first bracket portion 121 extending along the propagation direction of its own optical path is integrally formed with a side wall portion of the second bracket portion 122. It can also be understood that the extension direction of the side wall portion of the first bracket portion 121 integrally formed with a side wall portion of the second bracket portion 122 is the extension direction of the first bracket portion 121.

[0142] In some specific embodiments of the present application, on the basis of the adjacent arrangement of the light inlets 104 of the two corresponding camera module semi-finished products 70, when the first bracket part 121 and the second bracket part 122 are arranged in a Z shape, the first bracket part 121 extends along the light beam propagation direction (second direction Y axis) in the corresponding first semi-finished product 71, and the second bracket part 122 extends along the light beam propagation direction (second direction Y axis) in the corresponding second semi-finished product 72, and the extension direction of the first bracket part 121 and the extension direction of the second bracket part 122 are parallel to each other but in opposite directions. The first side wall part 12001 and the third side wall part 12003 of the first bracket part 121 extend along the light beam propagation direction (on the second direction Y axis) of the first bracket part 121, that is, the first side wall part 12001 or the third side wall part 12003 of the first bracket part 121 is integrally formed with a side wall part of the second bracket part 122.

[0143] In some optional embodiments, on the basis of the adjacent arrangement of the light entrance ports 104 of the two corresponding camera module semi-finished products 70, when the first bracket portion 121 and the second bracket portion 122 are arranged in parallel with an equal sign, the first bracket portion 121 extends along the light beam propagation direction (second direction Y axis) in the corresponding first semi-finished product 71, and the second bracket portion 122 extends along the light beam propagation direction (second direction Y axis) in the corresponding second semi-finished product 72, and the extension direction of the first bracket portion 121 and the extension direction of the second bracket portion 122 are parallel to each other but in the same direction.

[0144] like Figures 4 to 11As shown, on the basis of the adjacent arrangement of the light entrance ports 104 of the two corresponding semi-finished camera module 70, when the first bracket portion 121 and the second bracket portion 122 are arranged in a Z shape or in parallel with an equal sign, the light beam propagation direction of the first bracket portion 121 is parallel to the light beam propagation direction of the second bracket portion 122, and the first side wall portion 12001 and the third side wall portion 12003 of the first bracket portion 121 and the first side wall portion 12001 and the third side wall portion 12003 of the second bracket portion 122 are all extended and distributed along the light beam propagation direction (the second direction Y axis). When the third side wall portion 12003 of the first bracket portion 121 and the third side wall portion 12003 of the second bracket portion 122 are integrally formed, the first bracket portion 121 and the second bracket portion 122 are arranged in a Z shape; when the third side wall portion 12003 of the first bracket portion 121 and the first side wall portion 12001 of the second bracket portion 122 are integrally formed, the first bracket portion 121 and the second bracket portion 122 are arranged in parallel with an equal sign.

[0145] In some examples, the first side wall portion 12001 of the first bracket portion 121 and the third side wall portion 12003 of the second bracket portion 122 are integrally formed, or the first side wall portion 12001 of the first bracket portion 121 and the first side wall portion 12001 of the second bracket portion 122 are integrally formed to form a Z-shaped arrangement or an equal-sign parallel arrangement of the two.

[0146] like Fig.11 As shown, on the basis of the adjacent arrangement of the light entrance ports 104 of the two corresponding camera module semi-finished products 70, when the first bracket portion 121 and the second bracket portion 122 are arranged in an L shape, the first bracket portion 121 extends along the light beam propagation direction (the second direction Y axis) in the corresponding first semi-finished product 71, and the second bracket portion 122 extends along the light beam propagation direction (the third direction X axis) in the corresponding second semi-finished product 72, and the extension direction of the first bracket portion 121 and the extension direction of the second bracket portion 122 are perpendicular to each other. The first side wall portion 12001 and the third side wall portion 12003 of the first bracket portion 121 extend and are distributed along the propagation direction of the light beam (the second direction Y axis), and the first side wall portion 12001 and the third side wall portion 12003 of the second bracket portion 122 extend and are distributed in the transverse direction (the third direction X axis). The third side wall portion 12003 of the first bracket portion 121 and the second side wall portion 12002 of the second bracket portion 122 are integrally formed, and the first bracket portion 121 and the second bracket portion 122 are arranged in an L shape.

[0147] Specifically, the side wall portion of the first bracket portion 121 extending along the propagation direction of its own optical path is integrally formed with a side wall portion of the second bracket portion 122 except the fourth side wall portion 12004, forming a molding area 123 located between the two side wall portions of the two bracket portions, and the projection of the molding area 123 in the light beam propagation direction (the second direction Y axis) covers the projection of the light inlet 104 in the light beam propagation direction (the second direction Y axis), as shown in FIG. Figures 9 to 11 As shown, the first bracket portion 121 and the first shell 11001 are integrally formed, and the molding area 123 is located between the third side wall portion 12003 of the first bracket portion 121 and a side wall portion of the second bracket portion 122 except the fourth side wall portion 12004, and the projection of the area in the beam propagation direction (second direction Y axis) covers the projections of the light entrance port 104 on the first shell 11001 and the light entrance port 104 on other shells 11 in the beam propagation direction (second direction Y axis), so that the molding area 123 is located between the light entrance ports 104 of the multi-camera module 2 to ensure the adjacent setting of two adjacent light entrance ports 104, fix the relative positions of the two adjacent light entrance ports 104, and avoid the small displacement between the two bracket portions affecting the switching effect of different camera modules 1. The molding area 123 may also be implemented as being located between the first side wall portion 12001 of the first bracket portion 121 and a side wall portion of the second bracket portion 122 except the fourth side wall portion 12004 .

[0148] Among them, the end portion of the second bracket portion 122 that semi-encloses the light entrance port 104 of the second shell 11002 is the light entrance end portion, a portion of the first side wall portion 12001 on the second bracket portion 122, a portion of the third side wall portion 12003 and the second side wall portion 12002 together constitute the light entrance end portion of the second bracket portion 122, and the other end portion is the light exit end, and the first side wall portion 12001 of the first bracket portion 121 and a portion of the light entrance end on the second bracket portion 122 are integrally formed to form the molding area 123, that is, the first side wall portion 12001 of the first bracket portion 121 and a portion of the first side wall portion 12001 of the second bracket portion 122 constituting the light entrance end, and a portion of the third side wall portion 12003 of the second bracket portion 122 or the second side wall portion 12002 of the second bracket portion 122 are integrally formed to form the molding area 123.

[0149] More specifically, the molding area 123 is located between the front portion of the first side wall portion 12001 or the third side wall portion 12003 of the first bracket portion 121 in the light beam propagation direction (the second direction Y axis) and the light incident end portion of the second bracket portion 122, such as Figures 9 to 11As shown, no matter the first bracket portion 121 and the second bracket portion 122 are arranged in a Z shape, in parallel with equal signs, or in an L shape, the projection of the molding area 123 in the light beam propagation direction (the second direction Y-axis) simultaneously covers the projection of the light entrance port 104 on the first shell 11001 in the light beam propagation direction (the second direction Y-axis) and the projection of the light entrance end portion of the second bracket portion 122 in the light beam propagation direction (the second direction Y-axis), so as to ensure the stability of the relative positions of the two adjacent light entrance ports 104 on the multi-camera module 2.

[0150] Furthermore, the extension direction of the first bracket part 121 is different from the extension direction of the second bracket part 122, in order to reduce the magnetic interference generated between the driving components of the first semi-finished product 71 and the driving components of the second semi-finished product 72. On this basis, the driving components of the first bracket part 121 and the driving components of the second bracket part 122 are arranged alternately to further reduce the magnetic interference. The driving components include the light deflection driving component and the lens driving component. When the first bracket part 121 and the second bracket part 122 are arranged in a Z-shape, the lens driving components located in the two bracket parts are kept at a certain distance to avoid mutual interference, and the light deflection driving component is arranged on the side wall part without the molding area 123; when the first bracket part 121 and the second bracket part 122 are arranged in an L-shape, the lens driving components located in the two bracket parts and the light deflection driving components can maintain a certain distance because of the L-shaped arrangement, and the magnetic interference generated is relatively small.

[0151] In some optional embodiments, when the first bracket portion 121 and the second bracket portion 122 are arranged in parallel with an equal sign, the light deflection driving components located in the two bracket portions are arranged adjacent to but not opposite to each other, the lens driving component adopts unilateral drive, and the lens driving components located in the two bracket portions are arranged relatively to maintain a certain distance to avoid mutual interference.

[0152] Furthermore, at least one side wall of the bracket portion of the bracket 12 is provided with an avoidance area 1202, and the avoidance area 1202 corresponds to the conductive area between the pin 61 of the circuit assembly 60 and the circuit board 41 of the photosensitive component 40. After the housing 10 is installed, at least one bracket portion is integrally formed with a shell 11, covering at least part of the base 20, the lens assembly 30 and the photosensitive component 40 to form a closed space, so that the optical system and the drive system are located in the closed space, and then the pin 61 exposed in the avoidance area 1202 and the circuit board 41 of the photosensitive component 40 are welded to form a conductive connection, thereby reducing the risk of dirt generated by welding entering the interior and reducing the impact on the module assembly yield.

[0153] Among them, on the same bracket part, the positioning structure 103 and the avoidance area 1202 are arranged at different positions of the bracket part to avoid each other. Further, along the top view angle of the height direction (first direction Z axis), defined as the projection direction, the positioning structure 103 and the avoidance area 1202 are arranged at different positions of the side wall part 102 of the bracket 12 along the projection direction. The above design can prevent the positioning structure 103 from affecting the assembly process of the avoidance area 1202, and the staggered avoidance setting can further optimize the risk of the overall structural strength of the shell 10 being reduced due to the avoidance area 1202.

[0154] 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 formed in one piece by combining metal material and plastic material, that is, the first shell 11001 and the first bracket portion 121 of the housing 10 are formed in one piece by combining metal material and plastic material. Specifically, 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, and the bracket 12 is formed with at least a portion of the shell side wall 112 of the shell 11, that is, the first bracket portion 121 is formed in one piece with the second bracket portion 122, and the first bracket portion 121 is formed with at least a portion of the first shell 11001, to obtain the housing 10 formed in one piece to form a single part.

[0155] In the following production and manufacturing implementation scheme in which at least a portion of the shell 11 is combined with the bracket 12 for embedding molding, the shell 11 is implemented as the first shell 11001, and the bracket 12 is implemented as having at least two bracket parts, wherein the bracket 12 mainly refers to the first bracket part 121 combined with the first shell 11001 for embedding molding.

[0156] More specifically, at least a portion of the housing side wall 112 of the housing 11 used for injection molding is a joint area of ​​the housing side wall 112 of the housing 11. The joint area of ​​the housing side wall 112 is injected to form the bracket 12. The joint areas of the housing side wall 112 of the housing 11 located on different sides are injected to form different side wall portions of the bracket 12 located on different sides. The bracket 12 and the remaining area of ​​the housing side wall 112 together form the side wall portion 102 of the housing 10, and the housing cover wall 111 of the housing 11 forms the cover portion 101 of the housing 10.

[0157] 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.

[0158] 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 and formed around three sides of the housing cover wall 111. 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.

[0159] 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, 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 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. 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 are provided with the combining hole 1120.

[0160] like Fig.14 As shown, the shell side wall 112 includes a combining portion, and the combining hole 1120 is arranged in the combining portion. After the shell 11 is molded, the bracket 12 is molded around the combining portion so that the molding material enters the combining hole 1120, and the molding material is combined with the inner wall of the combining hole 1120, and the bracket 12 is molded together on the surface of the combining portion and the combining hole 1120.

[0161] 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 part, 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 coupling hole 1120 and the outer surface of the coupling part.

[0162] 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 .

[0163] 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 is provided, the second shell side wall 1122 and the fourth shell side wall are opposite to each other along the longitudinal direction (second direction Y axis) of the light beam propagation direction.

[0164] In the example where the fourth shell side wall exists in the shell 11, the bracket 12 forms the first side wall portion 12001, the second side wall portion 12002, the third side wall portion 12003 and the fourth side wall portion 12004 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 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 are respectively embedded in the first side wall portion 12001, the second side wall portion 12002, the third side wall portion 12003 and the fourth side wall portion 12004 to form an embedded relationship.

[0165] In the example where the fourth shell side wall does not exist in the shell 11, the bracket 12 forms the first side wall portion 12001, the second side wall portion 12002 and the third side wall portion 12003 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 12001, the second side wall portion 12002 and the third side wall portion 12003 to form an embedded relationship.

[0166] 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 an embodiment in which the housing 11 has the housing side wall 112, the first side surface 1101 is formed on the inner 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 surface of the bracket 12 and faces the base 20.

[0167] 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 1001, and the inner surface 1001 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 1001 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 embodiment of integrated die-casting, the first side surface 1101 and the second side surface 1201 are flush for easy demolding, and are conducive to simplifying mold design, improving production yield, and reducing costs.

[0168] 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.

[0169] In some examples, the bonding surface on the inner surface 106 of the housing 10 is provided on the first side surface 1101 of the housing side wall 112 of the housing 11 and on the second side surface 1201 of the bracket 12, for bonding and fixing the housing 10 and the base 20. Further, the bonding surface is only provided on the second side surface 1201 of the bracket 12 to ensure that the relative position between the housing 10 and the internal structure of the camera module 1 is fixed.

[0170] In one embodiment of the present application, the first housing 11001 is formed on one side of the first side wall portion 12001, the second side wall portion 12002 and the third side wall portion 12003 along the height direction (first direction Z axis). There is a spacing space 108 between the fourth side wall portion 12004 and the housing 11, and the spacing space 108 is formed between the light outlet 105 and the fourth side wall portion 12004, surrounded and defined by a portion of the first side wall portion 12001, the fourth side wall portion 12004 and a portion of the third side wall portion 12003, 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. The light outlet 105 is surrounded and defined by the inner surface of the first side wall portion 12001, the end of the housing cover wall 111 of the housing 11 and the inner surface of the third side wall portion 12003, and communicates with the partition space 108. The housing 11 is implemented as the first housing 11001.

[0171] Specifically, taking the camera module 1 as a periscope camera module 1, 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 be maintained 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.

[0172] Furthermore, the end of the base 20 defines an external packaging space 203 for installing the photosensitive component 40, and the light port 202 is located between the receiving space 200 and the external packaging space 203. In this embodiment of the housing 10, the photosensitive component 40 is installed in the external packaging 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 first shell 11001 of the housing 10 covers the receiving space 200, and the photosensitive component 40 located in the external packaging 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.

[0173] Specifically, the base 20 has a mounting seat 204 at the rear end in the direction of the optical path, the light opening 202 is formed on the mounting seat 204, the external packaging space 203 is formed between the light emitting side of the mounting seat 204 and the fourth side wall portion 12004, and is surrounded and defined by a portion of the first side wall portion 12001, the fourth side wall portion 12004, a portion of the third side wall portion 12003 and the mounting seat 204, and the photosensitive component 40 is installed in the external packaging space 203, so that the light beam emitted from the lens assembly 30 passes through the light opening 202 on the mounting seat 204 and reaches the photosensitive component 40 for imaging.

[0174] In some examples, the two sides of the mounting base 204 extend toward the inner surface of the first side wall portion 12001 and the inner surface of the third side wall portion 12003, respectively, and extend along the height direction (first direction Z axis) to abut the side of the first shell 11001, that is, abut the side of the shell 11 on the partition space 108. From the perspective of the drawings in the specification, the mounting base 204 is perpendicular to the bottom surface of the base 20 and the direction of light beam propagation to separate the receiving space 200 and the outer packaging space 203, so that the assembly process in the two spaces can be carried out simultaneously, further simplifying the assembly steps of the camera module 1.

[0175] Specifically, the top of the mounting base 204 is connected to the side of the first shell 11001 on the partition space 108 toward the receiving space 200, that is, there is no gap between the mounting base 204 and one side of the first shell 11001, and a sealed protective film is provided on the light entrance 104 on the cover portion 101 of the shell 10. Therefore, the receiving space 200 between the shell 10 and the base 20 is a closed space to isolate the internal structure of the camera module 1 placed in the receiving space 200 from the outside world, thereby reducing the risk of stains caused by debris and dust entering the receiving space 200 during the subsequent processing of assembly and welding, and avoiding the risk of affecting the imaging of the camera module 1.

[0176] Furthermore, the side wall of the mounting seat 204 facing the external packaging space 203 is provided with a mounting foot 2041. Figure 3 From the perspective of , the mounting foot 2041 on the mounting seat 204 is symmetrically arranged along the horizontal direction (the third direction X-axis), and a mounting groove for installing the photosensitive component 40 is formed between the mounting foot 2041 and the side wall of the mounting seat 204 facing the external packaging space 203, so as to further simplify the positioning, alignment and assembly process of the photosensitive component 40.

[0177] Furthermore, the mounting foot 2041 extends toward the outside of the base 20 to form an outer angle, which protrudes from the outer surface of the base 20 and abuts against a portion of the first side wall portion 12001 or a portion of the third side wall portion 12003 that forms the separation space 108, so that the shell 10 can be quickly positioned and assembled on the base 20, thereby avoiding assembly displacement between the shell 10 and the base 20, thereby causing eccentricity of the camera module 1.

[0178] The photosensitive component 40 includes a photosensitive chip, a circuit board 41 and a connecting belt 42. The photosensitive chip is connected to the circuit board 41. One side of the circuit board 41 is connected to the connecting belt 42. The connecting belt 42 extends from the circuit board 41 and is conductively connected to the electronic device through a connector 43 at the tail end, so that the circuit board 41 is conductively connected to the electronic device, thereby achieving conductivity between the camera module 1 and the electronic device. According to different adaptation requirements of the electronic device, the connecting belt 42 will be configured with different bending methods so that the connector 43 at the tail end is located in the most suitable position for welding 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 at its tail end is located on the side of the camera module 1, that is, on one side of the camera module 1 in the horizontal direction (third direction X-axis), or 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 at its tail end is located on one side of the camera module 1 in the longitudinal direction of the light beam propagation direction (second direction Y-axis), that is, in the length direction.

[0179] Depending on the different orientations of the connector 43 at the tail end of the connecting belt 42 relative to the bracket 12, different installation methods of the housing 10 need to be considered to avoid interference with the tail end connector 43 on the connecting belt 42. When the tail end connector 43 on the connecting belt 42 is located below the bracket 12, the connecting belt 42 extends from the bottom of the bracket 12, so that the connector 43 at its tail end is closer to the electronic device than the bracket 12, 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 tail end connector 43 on the connecting belt 42 is located above the bracket 12, the connecting belt 42 extends from the top of the bracket 12, the housing 10 is installed from top to bottom to the outside of the base 20 and the photosensitive component 40, and it is necessary to consider avoiding interference between the housing 10 and the connector 43.

[0180] 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 tail connector 43 on the connection belt 42 is located on one side of the longitudinal direction (second direction Y axis) of the non-light beam propagation direction of the camera module 1, the connection belt 42 can be connected from the bottom to avoid interference with the assembly of the housing 10.

[0181] In one embodiment of the present application, the first housing 11001 is formed on the top of the first side wall portion 12001, the second side wall portion 12002, the third side wall portion 12003 and the fourth side wall portion 12004, and the aforementioned spacing space 108 does not exist between the housing 11 and the fourth side wall portion 12004. The first housing 11001 integrally covers the receiving space 200 and the outer packaging 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 first housing 11001, that is, from the bottom, so that the connector 43 at the tail end thereof is located at the bottom and does not interfere with the assembly of the housing 10.

[0182] Among them, the attachment position of the connecting belt 42 after positioning the tail connector 43 after adopting the shell 10 of the present application is specifically introduced. In some examples, the connecting belt 42 is attached between the fourth side wall portion 12004 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 12004 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 12001 or the third side wall portion 12003 of the bracket 12 and the base 20, and the connector 43 at the tail end thereof can be led out from the inner side of the first side wall portion 12001 or the third side wall portion 12003 below the height direction (first direction Z axis). In other examples, the connecting strip 42 may be attached to the bottom of the camera module 1 so that the connector 43 at its tail end is located at the bottom of the camera module 1 .

[0183] In one embodiment of the present application, the connecting belt 42 extends from the circuit board 41 and is bent 180° on the side close to the bracket 12, extending from one side of the circuit board 41 to the other side from the bending point, and the bent extension surface is attached to the inner surface of the fourth side wall portion 12004, and the bent extension surface passes through the spacing space 108 at the top and is bent outward 90°, forming a secondary bend of the connecting belt 42, and extending to the connector 43 at the tail end, and the connector 43 at the tail end is located on the outside of the fourth side wall portion 12004.

[0184] Among them, the internal structure of the camera module 1 has some electronic components that need to be connected to the circuit, for example, one of the units of the lens drive component and the optical path turning drive component has electronic components. The camera module 1 also includes a circuit component 60 connecting the electronic components and the photosensitive component 40. Specifically, the circuit component 60 is arranged on the base 20 and has a pin 61 at the tail, and the pin 61 is exposed on the outer surface of the base 20. The circuit component 60 is welded to the circuit board 41 in the photosensitive component 40 through the pin 61.

[0185] In the prior art, the split housing 11 and the bracket 12 both have four housing side walls 112. The housing 11 has a certain assembly gap between the inner side of the housing side wall 112 and the base 20, and a certain assembly gap between the outer side of the housing side wall 112 and the bracket 12. The assembly gaps inside and outside the two housing side walls 112 parallel to the optical path are suitable for dispensing. The assembly gaps inside and outside the housing side wall 112 at the tail end of the optical path correspond to the photosensitive component 40 installed at the end of the optical path, and are suitable for accommodating the connection soft board that conducts the inside of the camera module 1 with the electronic device. Before the housing 11 and the bracket 12 are assembled to the base 20, the electronic components on the base 20 and the photosensitive component 40 are first welded, and the connection soft board is connected to the welding points. During the assembly stage, the connection soft board passes through the assembly gap between the base 20 and the housing 11 and the assembly gap between the housing 11 and the bracket 12 in turn, extends outward and connects the electronic device to conduct the camera module 1 and the electronic device.

[0186] The present application adopts a shell 10 in which a shell 11 and one of the bracket parts of a bracket 12 are integrally formed, and the thickness of the bracket 12 is retained in the thickness direction of the four side wall parts of the bracket part of the shell 10, thereby eliminating the thickness of the shell 11 and the assembly gap between the shell 11 and the bracket part of the bracket 12, and at the same time eliminating the amount of glue required for assembly glue, simplifying the assembly steps, and avoiding the offset problem of the shell 11 and the bracket 12 in the camera module 1 of the prior art and the eccentricity problem of the camera module 1.

[0187] In order to further simplify the assembly steps of the camera module 1, a groove-shaped avoidance area 1202 is provided on at least one bracket portion of the bracket 12, which is suitable for avoiding the connection area between the pin 61 and the circuit board 41. The avoidance area 1202 is formed in an area of ​​the bracket portion close to the photosensitive component 40 to cooperate with the welding of the pin 61 and the circuit board 41. It can be understood that the avoidance area 1202 is provided on the bracket portion of the bracket 12 corresponding to the projection area of ​​the external packaging space 203. Among the four side wall portions of the bracket portion constituting the bracket 12, the first side wall portion 12001 and the third side wall portion 12003 are the positions where the camera module 1 is fixed by glue, the second side wall portion 12002 is suitable for positioning the prism, and the fourth side wall portion 12004 corresponds to the assembly of the photosensitive component 40. In combination with the functions of each side wall portion, the avoidance area 1202 is preferably arranged on the first side wall portion 12001 and / or the third side wall portion 12003, such as Fig.12 and Fig.13As shown, the avoidance area 1202 is arranged at one end of the first side wall portion 12001 close to the fourth side wall portion 12004 and / or one end of the third side wall portion 12003 close to the fourth side wall portion 12004, so as to reduce the glue area on these two side wall portions 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.

[0188] Specifically, the avoidance zone 1202 is arranged at one end of the first side wall portion 12001 and / or one end of the third side wall portion 12003 close to the fourth side wall portion 12004, or the avoidance zone 1202 is arranged on the fourth side wall portion 12004, that is, it is arranged on the rear side of the first side wall portion 12001 along the optical path direction, the rear side of the third side wall portion 12003 along the optical path direction, or on the fourth side wall portion 12004, so as to adapt to the laying of the circuit component 60 arranged on the base 20 and the assembly orientation of the photosensitive component 40 on the camera module 1, and expose the connection area between the pin 61 and the circuit board 41 to achieve avoidance of the two.

[0189] More specifically, the avoidance zone 1202 extends from the bottom edge of the bracket portion of the bracket 12 and does not contact the bottom edge of the opposite side of the bracket 12, that is, a portion corresponding to the outer packaging space 203 extends toward the junction between the first shell 11001 and the bracket portion of the bracket 12, forming a groove that opens toward the bottom edge of the bracket portion of the bracket 12 and penetrates the bracket portion of the bracket 12 in the thickness direction, that is, forming the avoidance zone 1202, and the avoidance zone 1202 does not contact the first shell 11001 and the junction between the first shell 11001 and the bracket portion of the bracket 12.

[0190] In some embodiments, the avoidance area 1202 is formed by extending in the reverse direction from the bottom edge of the opposite side of the bracket portion of the bracket 12, that is, from a top portion of the bracket portion of the bracket 12, to the bottom edge of the bracket 12.

[0191] Among them, the thickness of the cover part 101 of the shell 10 along the height direction (first direction Z axis) and the thickness of the upper part of the side wall part 102 along the horizontal direction (third direction X axis) or along the longitudinal direction of the light beam propagation (second direction Y axis) are both the thickness H1 of the first shell 11001, and the thickness of the middle and lower part of the side wall part 102 along the horizontal direction (third direction X axis) or along the longitudinal direction of the light beam propagation (second direction Y axis) is the thickness H2 of the first bracket part 121 of the bracket 12. The thickness H1 is less than the thickness H2, while reducing the height of the camera module 1 while maintaining the mechanical strength of the shell 10. Therefore, in order to prevent the groove on the bracket 12 from affecting the mechanical strength of the shell 10, the extended tail end of the avoidance area 1202 does not contact the first shell 11001 and the junction between the first shell 11001 and the first bracket part 121 of the bracket 12, and avoids the area of ​​thickness H1 as much as possible to prevent the avoidance area 1202 from being processed and formed or the welding operation performed in the avoidance area 1202 from causing deformation of the first shell 11001.

[0192] Furthermore, the plane where the light entrance 104 on the first housing 11001 is located is perpendicular to the extension direction of the bottom edge of the avoidance area 1202 toward the first bracket portion 121 of the bracket 12. Figure 7 As shown, the plane where the light entrance 104 is located is the plane where the shell cover wall 111 on the first shell 11001 is located, so the extension direction of the bottom edge of the avoidance area 1202 facing the first bracket part 121 of the bracket 12 is perpendicular to the plane where the shell cover wall 111 is located.

[0193] In some examples, the bending structure of the connecting band 42 is located in the groove of the avoidance area 1202. At this time, the pin 61 and the circuit board 41 are arranged between a part of the first side wall portion 12001 / the third side wall portion 12003 and the bending structure of the connecting band 42. The avoidance area 1202 is arranged at the tail of the first side wall portion 12001 / the third side wall portion 12003 close to the fourth side wall portion 12004, and the pin 61, the circuit board 41 and the bending structure of the connecting band 42 are avoided at the same time to increase the welding operation space between the pin 61 and the circuit board 41.

[0194] The manufacturing process of the avoidance area 1202 is further explained. The processing of the avoidance area 1202 can be achieved by adding an inlay corresponding to the avoidance area 1202 during the integrated die-casting process. In one embodiment of the production and manufacturing of the shell 10 of the present application, the shell 11 and the bracket 12 are made of the same material. Taking aluminum alloy as an example, in the aluminum alloy integrated die-casting mold, an integrated mold with a raised inlay is pre-customized to form a corresponding position of at least one bracket part of the bracket 12, so that the avoidance area 1202 is formed synchronously with other structures of the shell 10.

[0195] In another embodiment of the production and manufacturing of the shell 10 of the present application, the shell 11 and the bracket 12 are made of different materials, and the two materials are integrally formed by a casting process. For example, in a manufacturing method in which a suitable mold is designed, two metals are poured into the mold for integral molding or are separately molded and then connected, a raised insert is set in advance at a corresponding position inside the molding mold of the bracket 12 to form the avoidance area 1202 of at least one bracket part on the bracket 12. In a manufacturing method in which the shell 11 is first obtained by stamping and then the shell 11 is used as an inlay of the molding mold of the shell 10, a raised insert is set in advance at a corresponding position inside the molding mold of the shell 10, or a detachable raised inlay is loaded into the molding mold of the shell 10 together with the shell 11, and then cast to obtain the shell 10 and the avoidance area 1202 of at least one bracket part on the bracket 12.

[0196] Reference Figure 12-13 The avoidance area 1202 is arranged at the rear side of the first side wall portion 12001 and / or the third side wall portion 12003 close to the fourth side wall portion 12004, and the avoidance area 1202 is composed of a portion of the first side wall portion 12001 / the third side wall portion 12003 along (the first direction Z axis), a portion of the fourth side wall portion 12004 along (the first direction Z axis), and a avoidance area connecting portion 1203 connecting the two. The height position of the avoidance area connecting portion 1203 can be determined according to the design requirements of the camera module 1, such as the upper part, the middle part, the lower part, etc., to match the position of the pin 61.

[0197] Specifically, the avoidance zone connection portion 1203 extends along or approximately along the lateral direction (third direction X-axis) and / or longitudinal direction (second direction Y-axis) of the camera module 1 in the direction of light beam propagation, so that the bracket 12 maintains its integrity around the base 20, thereby reducing the impact on the mechanical strength of the shell 10.

[0198] The avoidance zone connection portion 1203 is in a straight line, L-shaped, or other shape that can achieve a corner connection. Fig.12 and Fig.13 From the perspective of, the avoidance area connecting portion 1203 extends from the first side wall portion 12001 / the third side wall portion 12003 along the longitudinal direction of the light beam propagation direction (the second direction Y axis), and bends to connect to the fourth side wall portion 12004 when it reaches the plane where the fourth side wall portion 12004 is located.

[0199] Furthermore, the inner surface of the avoidance zone connecting portion 1203 or the inner surface of the fourth side wall portion 12004 forms a receiving groove close to the fourth side wall portion 12004, which is suitable for receiving a part of the bending structure of the connecting belt 42 to attach Fig.12From the perspective of , since the connecting belt 42 is arranged closely against the fourth side wall portion 12004 and the outermost side of its bending structure protrudes from the outer surface of the second side wall portion 12002, the avoidance area connecting portion 1203 is bent outward in two sections at the position corresponding to the bending structure of the connecting belt 42, forming a U-shaped groove with an opening toward the bending structure of the connecting belt 42, so as to accommodate the top of the bending structure of the connecting belt 42.

[0200] 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. The avoidance area connecting portion 1203 is located between the partition space 108 and the avoidance area 1202 to separate the partition space 108 from the avoidance area 1202, so as to prevent the bracket 12 from affecting the mechanical strength of the bracket 12 due to the large space occupied by the connected space, and to prevent the bracket 12 from being deformed due to external force during the assembly process.

[0201] 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 a bracket portion of the bracket 12 and the base 20 to connect the camera module 1 and the electronic device.

[0202] In some examples, the gap between the base 20 and the fourth side wall portion 12004 can be implemented to be connected to the avoidance area 1202 located on the fourth side wall portion 12004. During the processing and molding process, the connected gap and the avoidance area 1202 can be formed by adding a single inlay die-casting in the molding mold of the bracket 12 to simplify the hollow structure on the fourth side wall portion 12004 and its manufacturing and molding operations, thereby achieving avoidance of the pin 61, the connection area of ​​the circuit board 41, and the connecting band 42.

[0203] When the avoidance area 1202 is not set on the bracket 12, the positioning structure 103 is usually respectively arranged on four parts of the bracket 12, that is, the first side wall portion 12001, the second side wall portion 12002, the third side wall portion 12003 and the fourth side wall portion 12004 are each provided with at least one positioning structure 103 to ensure a stable connection between the camera module 1 and the electronic device. After the avoidance zone 1202 is set on the bracket 12, the positioning structure 103 is set on the bracket 12 away from the avoidance zone 1202 to avoid the two being too close to interfere with each other. When the two are too close, the force applied to the positioning structure 103 during fixed installation may cause the avoidance zone 1202 to deform, thereby affecting the avoidance effect and interfering with subsequent welding operations. At the same time, the hollow structure of the avoidance zone 1202 will affect the mechanical strength of the positioning structure 103 and the adjacent parts of the bracket 12 that are too close, and it is even possible that the positioning structure 103 will break during the fixed installation stage.

[0204] Specifically, when the avoidance area 1202 is located on the first side wall portion 12001 / the third side wall portion 12003 , the positioning structure 103 on the same side as the avoidance area 1202 is disposed on the first side wall portion 12001 / the third side wall portion 12003 .

[0205] More specifically, the avoidance zone 1202 and the positioning structure 103 on the same side are not located in the same height direction (first direction Z axis), so that the positioning structure 103 avoids the avoidance zone 1202 to prevent the fixed installation operation from having an adverse effect on the structural strength of the avoidance zone 1202.

[0206] Furthermore, when the number of the positioning structures 103 is not greater than four, at least two of the positioning structures 103 are respectively arranged at the two end points of the diagonal of at least one bracket portion of the bracket 12, or at least two of the positioning structures 103 are symmetrically arranged on the second side wall portion 12002 and the third side wall portion 12003, and at least one of the positioning structures 103 is arranged on the first side wall portion 12001, so that the positioning structure 103 is arranged as far away from the avoidance area 1202 as possible to avoid mutual interference between the two and affect the mechanical strength of the bracket 12.
