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

Camera module
[0040] The shell 10 and the base 20 may be connected by various methods such as gluing, welding, interference fit, snap connection, mechanical connection, threading, and hinge. In one optional embodiment, the shell 10 and the base 20 are connected by gluing.
[0041] 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.
[0042] 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.
[0043] Furthermore, the semi-finished camera module 70 of the camera module 1 may further include a lens driving assembly, which is used to drive the lens assembly 30 to move, so as to adjust the focus and achieve the purpose of automatic focusing and / or zooming. The lens driving assembly includes a first driving unit and a second lens driving unit, the first driving unit is installed on the base 20, and the second driving unit is installed on the lens assembly 30, and the first driving unit and the second lens driving unit interact with each other to drive the lens assembly 30 to move relative to the base 20.
[0044] 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. In other embodiments of the driving form of the present application, the lens driving assembly is implemented as a piezoelectric motor drive, an SMA (Shape Memory Alloys) drive, a stepper motor or other drive methods.
[0045] For the purpose of convenience of description, the height or thickness direction of the camera module is defined as the Z axis, and the height direction of the camera module is the thickness direction of the electronic device on which the camera module is installed. The horizontal and vertical directions that are orthogonal to the height direction of the camera module and perpendicular to each other are defined as the X axis and the Y axis, respectively.
[0046] The types of camera modules include upright camera modules, periscope camera modules, other types of telephoto camera modules and other forms.
[0047] In one embodiment of the present application, the camera module 1 is implemented as a periscope camera module for example. The camera module semi-finished product 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 faces the incident side of the lens assembly 30. After the optical path turning component 50 turns the direction of the incident light, it passes through the lens assembly 30 to reach the photosensitive component 40 for imaging.
[0048] The optical path turning component 50 turns the incident light beam along the first direction (Z axis) in the height direction 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 (second direction Y axis) of the light beam from the light incident side to the light exit side.
[0049] 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 horizontally (the third direction X-axis) to achieve 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 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 motion; 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 motion.
[0050] The above example illustrates an example in which the optical path deflection component 50 is disposed on the incident side of the lens assembly 30. In other periscope camera modules, the optical path deflection component 50 is disposed between the lens assembly 30 and the photosensitive assembly 40 to deflect the direction of the light beam at least once after the light beam is emitted from the lens assembly 30 and before it is incident on the photosensitive assembly 40.
[0051] In other parts of the periscope camera module, multiple optical path deflection components 50 are included, at least one of which can be arranged in front of the incident side of the lens assembly 30 to deflect the direction of the light beam at least once before the light beam is incident on the lens assembly 30, and at least one of which can be arranged between the lens assembly 30 and the photosensitive component 40 to deflect the direction of the light beam at least once after the light beam is emitted from the lens assembly 30 and before it is incident on the photosensitive component 40.
[0052] In other periscope camera modules, other lenses may be arranged in front of the incident side of the optical path turning component 50 so that the light beam passes through the lens before entering the optical path turning component 50 .
[0053] 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.
[0054] 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.
[0055] 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.
[0056] 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.
[0057] The lens driving assembly and the optical path deflection driving assembly may adopt the same driving form or different driving forms.
[0058] [Housing 10] Reference Manual Attached Figures 1 to 8 , the shell 11 and the bracket 12 of the shell 10 are integrally formed to form a single component. That is to say, the shell 10 is an integrally formed component. Among them, the shell 11 is suitable for covering the base 20 to cover at least a portion of the internal structure of the semi-finished camera module 70, and a light inlet 104 is opened on the shell 11; the bracket 12 has at least four side walls and is used to surround at least a portion of the circumference of the semi-finished camera module 70, and is connected to the shell 11, and the thickness of the bracket 12 is not less than the thickness of the shell 11, which is suitable for the installation of the camera module and the electronic device, so that the camera module is fixed to the electronic device. In an optional embodiment of the present application, the shell of the shell 10 mainly plays the role of controlling stray light and covering the top surface, and the bracket 12 plays the role of peripheral protection. Specifically, the minimum thickness of the bracket 12 is not less than the minimum thickness of the shell. Furthermore, the minimum thickness of the shell may correspond to a different material than the material covered by the bracket 12, and the materials may be formed based on different processing methods, thereby ensuring that the minimum thickness of the bracket 12 is not less than the minimum thickness of the shell. The housing 10 of the present application adopts an integrated design, integrating the functions of the shell and bracket 12 of the camera module of 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.
[0059] In the following text, the unnumbered housing and bracket refer to the housing and bracket in the prior art, and the numbered housing 11 and bracket 12 refer to the housing 11 and bracket 12 in the present application.
[0060] Among them, at least one side wall 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 assembly 40. After the housing 10 is installed, it covers at least part of the base 20, the lens assembly 30 and the photosensitive assembly 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 assembly 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.
[0061] 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.
[0062] 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.
[0063] 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. By using aluminum alloy integrated die-casting, such as aluminum-magnesium alloy, etc., the lightweight characteristics of the material are utilized to achieve a weight reduction effect, thereby reducing the weight of the housing 10 and the camera module. 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. 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.
[0064] 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 lateral and longitudinal directions of the camera module, the wall thickness of the shell 11 can be saved on one side, that is, the size is reduced by 0.2 mm. The lateral and longitudinal dimensions of the camera module are reduced, and more design space can also be provided when components such as motors and lenses become further larger.
[0065] The above data is only used to illustrate the advantages of the integrated design adopted by the shell 10 of the present application. Depending on the design of the camera module, the size that can be saved is different. More size can be saved, or less size can be saved. However, the wall thickness of the shell of the prior art can at least be reduced based on the integrated design.
[0066] 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.
[0067] In other examples of the present application, other materials such as zinc alloy, magnesium alloy, tin-based alloy, copper alloy, etc. can also be used for integrated die-casting to manufacture the shell 10 of the present application.
[0068] 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.
[0069] 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.
[0070] 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.
[0071] 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.
[0072] Next, the structure of the housing 10 of the present application is described in detail.
[0073] 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, extending in the horizontal direction, and the side wall portion 102 is bent from the outer periphery of the cover portion 101 and extends and distributes along the height direction (first direction Z axis) or approximately along the height direction (first direction Z axis). Figure 1-5 It can be understood that 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 the side portion.
[0074] The cover portion 101 and the side wall portion 102 jointly define the housing covering space 1000 of the housing 10. The housing 10 also has an installation opening 100. The housing 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 housing covering space 1000. The installation opening 100 is surrounded and defined by the bracket 12. Specifically, the bracket 12 defines the lower end of the housing 10 (i.e., the end close to the mainboard side of the electronic device), and the shell 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 shell 11 extends from the upper end of the housing 10 to the bracket 12, and the bracket 12 continues to verify and define the lower end of the housing 10.
[0075] The cover part 101 has a thickness H1 along the height direction (first direction Z axis), and the side wall part 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 in the height direction (first direction Z axis) is as small as possible to reduce the height of the camera module, which can be adapted to the smaller thickness of the electronic equipment and meet the requirements of miniaturization of the camera module. In some optional embodiments, the thickness of any position of the cover part 101 does not exceed the thickness of any position of the side wall part 102. Since the main function of the cover part 101 is to cover the internal structure of the camera module, its thickness size only needs to ensure that the cover part 101 can be formed, so H1 can be as small as possible while ensuring strength to reduce the size of the camera module. The side wall part 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 part 101, and the thickness H2 is implemented as the minimum thickness of the side wall part 102.
[0076] The side wall portion 102 is sleeved on the outside of the base 20. Further, in some examples of the present application, at least a portion of the bottom of the side wall portion 102 is flush with at least a portion of the bottom of the base 20. In other words, there is a flush portion of the lower end surface of the side wall portion 102 that is flush with the lower end surface of the base 20, so as to bias the installation of the housing 10 on the base 20 and improve the assembly accuracy in the height direction (first direction Z axis). In other examples of the present application, at least a portion of the bottom of the side wall portion 102 further protrudes downward relative to the bottom of the base 20.
[0077] refer to Figure 8 As shown, the side wall portion 102 is provided with a mounting structure 103. Specifically, the mounting structure 103 is arranged on the outside of the bracket 12, suitable for the camera module to be installed on the electronic device, and / or suitable for the camera module and other camera modules to be fixed to form a multi-camera module. Among them, the mounting structure 103 and the avoidance area 1202 are arranged at different positions of the bracket 12 to avoid each other. Further, the top view along the height direction (first direction Z axis) is defined as the projection direction, and the mounting structure 103 and the avoidance area 1202 are arranged at different positions of the side wall portion 102 of the bracket 12 along the projection direction. The above design can prevent the mounting structure 103 from affecting the assembly process of the avoidance area 1202, and the staggered avoidance setting can further optimize the risk of decreased overall structural strength of the shell 10 caused by the avoidance area 1202.
[0078] The cover portion 101 , the side wall portion 102 and the mounting 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 .
[0079] In one embodiment of the present application, the housing 10 is installed on the base 20 of one camera module to form a housing 11 of the camera module; in one embodiment of the present application, the housing 10 is installed on the bases 20 of multiple camera modules, that is, the housing covering space 1000 can accommodate multiple camera modules to form multiple housings 11 of the camera modules. In other words, the housing 11 and the bracket 12 of a single camera module can be designed in an integrated manner, and the housing 11 and the bracket 12 of multiple camera modules can also be designed in an integrated manner.
[0080] The mounting 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 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 and fixed so that the camera module is connected to other camera modules.
[0081] In other examples, the mounting 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 and the electronic device can be buckled and fixed by glue. In other examples, other suitable fixing methods can also be implemented.
[0082] Since the housing 10 is made of metal material, if the camera module 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 chipping when they are matched, thus avoiding the generation of foreign matter.
[0083] 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.
[0084] 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, and the outer surface 107 faces the outside of the camera module. An inner connection structure is formed between the inner surface 106 and the internal structure of the camera module, and an inner and outer connection structure is formed between the outer surface 107 and the external structure of the camera module. 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 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 is installed in the electronic device. Thus, the position of the camera module 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.
[0085] The inner surface 106 is defined by the inner surface of the housing 11 and the inner surface of the bracket 12 , and the outer surface 107 is defined by the outer surface of the housing 11 and the outer surface of the bracket 12 .
[0086] 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.
[0087] Next, the specific structures of the shell 11 and the bracket 12 included in the housing 10 are further described.
[0088] 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.
[0089] 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 a plane where the diameter of the light entrance 104 is located, or is approximately distributed along a 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 (the first direction Z axis).
[0090] 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 .
[0091] 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.
[0092] 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.
[0093] 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.
[0094] Therefore, when the shell 11 and the bracket 12 are integrally formed to form the housing 10, the thickness of the shell 11 can be omitted at the overlap of the bracket 12 and the shell 11, or the bracket 12 and the shell 11 are stacked in the height direction (first direction Z axis), saving the thickness of the shell 11 in the horizontal and vertical dimensions. Furthermore, since the shell 11 and the bracket 12 are integrally formed, compared with the separate bracket 12 and shell in the prior art, the use of the shell 10 saves the process of assembling the bracket 12 to the shell, and also saves the glue between the bracket 12 and the shell.
[0095] 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, 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.
[0096] 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 is assembled on an electronic device, after the bracket and the electronic device are fixed, the connection structure between the bracket and the housing 11 fails, the camera module may become loose, displaced, etc., resulting in a decrease in the performance of the camera module 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 are realized, and the glue between the bracket and the housing 11 is omitted, which can reduce the risk points of the camera module and improve the reliability of the camera module.
[0097] Furthermore, the glue between the bracket and the housing 11 is omitted, which can specifically omit the glue selection and verification, glue position selection and verification, glue quantity (such as total glue quantity, glue width, glue length, glue thickness, etc.) verification, tooling and jig production and verification of the glue 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 and the housing 11 can save production, assembly and other processes and engineering, improve the production efficiency and production yield of the camera module, and can improve the appearance yield of the camera module.
[0098] In addition, in the camera module of the prior art, the glue will be pulled by 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 of the base 20, and the position and / or shape of the components located in the receiving space, etc., affecting the performance and reliability of the camera module. Therefore, after avoiding the glue between the bracket 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.
[0099] Specifically in terms of assembly, first, the assembly process is simplified, and the two assemblies of the housing and the bracket in the prior art are optimized to a single assembly of the housing 10 of the present application, eliminating the glue setting and glue curing processes, and reducing assembly tolerances. In addition, the integration of the housing 11 and the bracket 12 can also optimize the eccentricity problem of the camera module caused by the bracket assembly in the prior art.
[0100] Specifically, in the camera module of the prior art, there is an assembly gap between the bracket and the housing 11, which will cause the housing 11, together with the base 20 of the camera module and its internal structure, to be offset in the bracket, causing the light hole provided on the housing 11 to be offset relative to the bracket. Therefore, when the bracket is assembled to the housing 11, the light hole of the camera module may have been offset. After the camera module is assembled to the electronic device, the offset may be more serious, which causes the light hole of the electronic device and the light hole of the camera module to be offset, resulting in an eccentricity problem of the camera module. In addition, the glue between the bracket and the housing 11 will also affect the relative position between the bracket and the housing 11, aggravating the offset problem between the light hole and the bracket, making the final light hole of the electronic device and the light hole of the camera module offset more serious.
[0101] 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 in the camera module of the prior art. In other words, the relative position between the light inlet 104 of the shell 10 and the mounting structure 103 remains unchanged. Therefore, when the camera module is installed on the electronic device, the alignment of the light inlet 104 of the camera module and the light hole of the electronic device can be achieved through the precise alignment of the mounting structure 103 and the electronic device, thereby avoiding the eccentricity problem of the camera module caused by the offset of the light inlet 104, thereby improving the assembly yield of the camera module. Furthermore, the assembly eccentricity problem of the camera module can be controlled by controlling the manufacturing tolerance of the distance between the light inlet 104 and the mounting structure 103; the assembly eccentricity problem of the camera module can be controlled by controlling the manufacturing tolerance of the distance between the light inlet 104 and the bracket 12.
[0102] It is understandable that, according to the design requirements of the camera module, 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, and extended service life. For example, surface treatments such as laser engraving and black coating may be performed on specific areas of the surface of the shell cover wall 111 to improve stray light.
[0103] The bracket 12 is sleeved outside the base 20 and surrounds the base 20 for one week to form a protective structure outside the camera module, which can provide physical protection for the camera module and prevent damage caused by dropping, impact or other external forces. The bracket 12 is used to fix the camera module at a specific position in the electronic device to ensure the accurate relative position with other components, so as to ensure the accuracy and stability of image capture. When the camera module is working, heat may be generated, and the bracket 12 can assist in heat dissipation to help the camera module work at an appropriate temperature and extend its service life. The bracket 12 can enhance the structural stability of the camera module. In some possible implementation manners, the bracket 12 can provide a certain degree of electromagnetic shielding to prevent electromagnetic interference from affecting the camera quality.
[0104] 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 121, a second side wall portion 122, a third side wall portion 123 and a fourth side wall portion 124 located on different sides. The first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124 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 121 and the third side wall portion 123 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 122 and the fourth side wall portion 124 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 124 is located on the light-emitting side of the camera module. The first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124 respectively have heights extending and distributed along the height direction (the first direction Z-axis), and jointly enclose to form the bracket 12.
[0105] Among them, the specific shape of the bracket 12 can be determined in combination with the design requirements of the camera module and the adaptation requirements of the electronic device.
[0106] 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.
[0107] The shape of the bracket 12 can be frame type, L type, U type, "mouth" type, etc.
[0108] 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. 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, that is, the bracket 12 is molded with at least a portion of the shell side wall 112 of the shell 11 to obtain the housing 10 formed in one piece as a single part.
[0109] 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.
[0110] 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.
[0111] 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.
[0112] 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.
[0113] like Figure 9-10 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.
[0114] 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 and the coupling hole 1120 of the coupling portion. 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 portion.
[0115] Among them, 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, 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.
[0116] 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.
[0117] In the example where the fourth shell side wall exists in the shell 11, the bracket 12 forms the first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124 on the first shell side wall 1121, the second shell side wall 1122, the third shell side wall 1123 and the fourth shell side wall, 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 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124 to form an embedded relationship.
[0118] 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 121, the second side wall portion 122 and the third side wall portion 123 on the first shell side wall 1121, the second shell side wall 1122 and the third shell side wall 1123, respectively, so that the first shell side wall 1121, the second shell side wall 1122 and the third shell side wall 1123 are respectively embedded in the first side wall portion 121, the second side wall portion 122 and the third side wall portion 123 to form an embedded relationship.
[0119] The positional relationship between the housing side wall 112 of the housing 11 and the bracket 12 is specifically described. The housing 11 has a first side surface 1101. In the embodiment in which the housing 11 has the housing side wall 112, the first side surface 1101 is formed on the inner side surface of the housing side wall 112 and faces the base 20. The bracket 12 has a second side surface 1201. The second side surface 1201 is formed on the inner side surface of the bracket 12 and faces the base 20.
[0120] 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.
[0121] 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.
[0122] In some examples, the adhesive 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 adhesively fixing the housing 10 and the base 20. Further, the adhesive 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 is fixed.
[0123] In one embodiment of the present application, the housing 11 is formed on one side of the first side wall portion 121, the second side wall portion 122 and the third side wall portion 123 along the height direction (first direction Z axis). There is a spacing space 108 between the fourth side wall portion 124 and the housing 11, and the spacing space 108 is formed between the light outlet 105 and the fourth side wall portion 124, and is surrounded and defined by a part of the first side wall portion 121, the fourth side wall portion 124 and a part of the third side wall portion 123, and is formed on the side of the housing 11. After the camera module is assembled, the photosensitive component 40 is accommodated in the spacing space 108. Among them, the light outlet 105 is surrounded and defined by the inner surface of the first side wall portion 121, the end of the housing cover wall 111 of the housing 11 and the inner surface of the third side wall portion 123, and is connected to the spacing space 108.
[0124] Specifically, taking the camera module as a periscope camera module as an example, the light port 202 is located at the exit side of the lens assembly 30, and the photosensitive component 40 is installed on one side of the light port 202, so that the light beam can reach the photosensitive component 40 for imaging after passing through the lens assembly 30. The photosensitive component 40 and the base 20 are fixed to remain on one side of the light port 202. After the housing 10 is installed outside the base 20, the bracket 12 is sleeved on the outside of the photosensitive component 40.
[0125] Furthermore, the end of the base 20 defines an installation space 203 for installing the photosensitive component 40, and the light port 202 is located between the receiving space 200 and the installation space 203. In this embodiment of the housing 10, the photosensitive component 40 is installed in the installation space 203, and after being fixed to the base 20, the housing 10 is installed outside the base 20, and the housing 10 surrounds the base 20 and the photosensitive component 40. Among them, the shell 11 of the housing 10 covers the receiving space 200, and the photosensitive component 40 located in the installation space 203 can be exposed through the spacing space 108 to avoid interference between the installation of the housing 10 and the photosensitive component 40.
[0126] 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 mounting space 203 is formed between the light emitting side of the mounting seat 204 and the fourth side wall portion 124, and is surrounded and defined by a portion of the first side wall portion 121, the fourth side wall portion 124, a portion of the third side wall portion 123 and the mounting seat 204, and the photosensitive component 40 is installed in the installation 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.
[0127] In some examples, the two sides of the mounting seat 204 extend toward the inner surface of the first side wall portion 121 and the inner surface of the third side wall portion 123, respectively, and extend along the height direction (first direction Z axis) to abut the side of the outer shell 11, that is, abut the side of the outer shell 11 on the partition space 108. From the perspective of the drawings in the specification, the mounting seat 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 installation 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.
[0128] Specifically, the top of the mounting base 204 is connected to the side of the outer shell 11 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 outer shell 11, 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 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.
[0129] Furthermore, the side wall of the mounting seat 204 facing the mounting space 203 is provided with mounting feet 2041. Figure 5 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 mounting space 203, so as to further simplify the positioning, alignment and assembly process of the photosensitive component 40.
[0130] 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 121 or a portion of the third side wall portion 123 that forms the separation space 108, so that the shell 10 can be quickly positioned and assembled on the base 20, avoiding assembly displacement between the shell 10 and the base 20, thereby causing an eccentricity problem of the camera module.
[0131] 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 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, that is, on one side of the camera module in the horizontal direction (third direction X-axis), or on one side of the camera module 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 (second direction Y-axis) of the light beam propagation direction, that is, in the length direction.
[0132] 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.
[0133] 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, the connection belt 42 can be connected from the bottom to avoid interference with the assembly of the housing 10.
[0134] In one embodiment of the present application, the housing 11 is formed on the top of the first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124, and the aforementioned spacing space 108 does not exist between the housing 11 and the fourth side wall portion 124. The housing 11 integrally covers the receiving space 200 and the installation space 203 of the base 20, and the connecting belt 42 of the photosensitive component 40 can be connected from the direction opposite to the housing 11, 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.
[0135] Among them, the attachment position of the connecting belt 42 after positioning the tail connector 43 after adopting the housing 10 of the present application is specifically introduced. In some examples, the connecting belt 42 is attached between the fourth side wall portion 124 of the bracket 12 and the photosensitive component 40, or in other words, the connecting belt 42 is fixed on the back of the photosensitive component 40. The connector 43 is led out from the inner side of the fourth side wall portion 124 above or below the height direction (first direction Z axis). In some examples, the connecting belt 42 is attached between the first side wall portion 121 or the third side wall portion 123 of the bracket 12 and the base 20, and the connector 43 at the tail end thereof can be led out from the inner side of the first side wall portion 121 or the third side wall portion 123 below the height direction (first direction Z axis). In other examples, the connecting belt 42 can be attached to the bottom of the camera module so that the connector 43 at the tail end thereof is located at the bottom of the camera module.
[0136] 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 extended surface after the bending is attached to the inner surface of the fourth side wall portion 124, and the extended surface after the bending 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 124.
[0137] Among them, the internal structure of the camera module 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 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.
[0138] In the prior art, the split housing 11 and the bracket 12 both have four housing side walls. The housing 11 has a certain assembly gap between the inner side of its housing side wall and the base 20, and a certain assembly gap between the outer side of its housing side wall and the bracket 12. The assembly gaps on the inner and outer sides of the two housing side walls parallel to the optical path are suitable for dispensing. The assembly gaps on the inner and outer sides of the housing side wall 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 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 and the electronic device.
[0139] The present application adopts a shell 10 in which the outer shell 11 and the bracket 12 are integrally formed, and the thickness of the bracket 12 is retained in the thickness direction of the four side wall portions of the bracket 12 of the shell 10, thereby eliminating the thickness of the outer shell 11 and the assembly gap between the outer shell 11 and the bracket 12, and at the same time eliminating the amount of glue required for assembly painting glue, thereby simplifying the assembly steps and avoiding the offset problem of the outer shell 11 and the bracket 12 in the camera module of the prior art and the eccentricity problem of the camera module.
[0140] In order to further simplify the assembly steps of the camera module, a groove-shaped avoidance area 1202 is provided on 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 the area of the bracket 12 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 12 corresponding to the projection area of the installation space 203. Among them, among the four side wall portions constituting the bracket 12, the first side wall portion 121 and the third side wall portion 123 are the positions for fixing the camera module by gluing, the second side wall portion 122 is suitable for positioning the prism, and the fourth side wall portion 124 corresponds to the assembly of the photosensitive component 40. In combination with the functions of each side wall portion, the avoidance area 1202 is preferably provided on the first side wall portion 121 and / or the third side wall portion 123, such as Figure 6 and Figure 7 As shown, the avoidance area 1202 is arranged at one end of the first side wall portion 121 close to the fourth side wall portion 124 and / or one end of the third side wall portion 123 close to the fourth side wall portion 124, so as to reduce the glue area on the 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 the excessive glue area, especially the bending of the position and path of the lens and the focus motor, and further avoiding the eccentricity problem of the camera module.
[0141] Specifically, the avoidance area 1202 is arranged at one end of the first side wall portion 121 and / or one end of the third side wall portion 123 close to the fourth side wall portion 124, or the avoidance area 1202 is arranged on the fourth side wall portion 124, that is, it is arranged on the trailing side of the first side wall portion 121 along the optical path direction, on the trailing side of the third side wall portion 123 along the optical path direction, or on the fourth side wall portion 124, 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, and to expose the connection area between the pin 61 and the circuit board 41 to achieve avoidance of the two.
[0142] More specifically, the avoidance area 1202 extends from the bottom edge of the bracket 12 and does not contact the bottom edge of the opposite side of the bracket 12, that is, a portion of the corresponding installation space 203 extends toward the junction of the shell 11 and the bracket 12, forming a groove that opens toward the bottom edge of the bracket 12 and penetrates the bracket 12 from the thickness direction, that is, forming the avoidance area 1202, and the avoidance area 1202 does not contact the shell 11 and the junction of the shell 11 and the bracket 12.
[0143] In some embodiments, the avoidance zone 1202 is formed by extending in the opposite direction from the bottom edge of the opposite side of the bracket 12, that is, from a portion of the top of the bracket 12, to the bottom edge of the bracket 12.
[0144] 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 direction (second direction Y axis) are all the thickness H1 of the shell 11, 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 direction (second direction Y axis) is the thickness H2 of the bracket 12. The thickness H1 is less than the thickness H2, and the mechanical strength of the shell 10 is maintained while reducing the height of the camera module. Therefore, in order to avoid the groove on the bracket 12 affecting the mechanical strength of the shell 10, the extended tail end of the avoidance area 1202 does not contact the shell 11 and the junction between it and the bracket 12, and avoids the area of thickness H1 as much as possible, so as to avoid the processing and forming of the avoidance area 1202 or the welding operation performed in the avoidance area 1202 causing the shell 11 to deform.
[0145] Furthermore, the plane where the light entrance 104 of the housing 11 is located is perpendicular to the extension direction of the avoidance area 1202 toward the bottom edge of the bracket 12. Figure 2 As shown, the plane where the light entrance 104 is located is the plane where the shell cover wall 111 of the shell 11 is located, so the extension direction of the avoidance area 1202 towards the bottom edge of the bracket 12 is perpendicular to the plane where the shell cover wall 111 is located.
[0146] Furthermore, the diameter direction of the light entrance 104 of the housing 11 is perpendicular to the extension direction of the avoidance area 1202 toward the bottom edge of the bracket 12 .
[0147] 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 portion of the first side wall portion 121 / the third side wall portion 123 and the bending structure of the connecting band 42. The avoidance area 1202 is arranged at the tail of the first side wall portion 121 / the third side wall portion 123 close to the fourth side wall portion 124, 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.
[0148] 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 set at the corresponding position of the bracket 12 is pre-customized to form the avoidance area 1202 synchronously with the other structures of the shell 10.
[0149] 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 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 on the bracket 12.
[0150] Reference Figure 6-7The avoidance area 1202 is arranged at the rear side of the first side wall portion 121 and / or the third side wall portion 123 close to the fourth side wall portion 124, and the avoidance area 1202 is composed of a portion of the first side wall portion 121 / the third side wall portion 123 along (the first direction Z axis), a portion of the fourth side wall portion 124 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, such as the upper part, the middle part, the lower part, etc., to match the position of the pin 61.
[0151] 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.
[0152] The avoidance zone connection portion 1203 is in a straight line, L-shaped, or other shape that can achieve a corner connection. Figure 6 and Figure 7 From the perspective of , the avoidance area connecting portion 1203 extends from the first side wall portion 121 / the third side wall portion 123 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 124 when it reaches the plane where the fourth side wall portion 124 is located.
[0153] Furthermore, the inner surface of the avoidance zone connecting portion 1203 or the inner surface of the fourth side wall portion 124 forms a receiving groove close to the fourth side wall portion 124, which is suitable for receiving a part of the bent structure of the connecting belt 42 to attach Figure 6 From the perspective of, since the connecting belt 42 is arranged closely against the fourth side wall portion 124 and the outermost side of its bending structure protrudes from the outer surface of the second side wall portion 122, 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.
[0154] Attach Figure 6-7 From the perspective of FIG. 1 , 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 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 the influence of external force during the assembly process.
[0155] In another specific embodiment of the present application, the housing 11 does not have the spacing space 108, and the connecting belt 42 extends from the gap between the bracket 12 and the base 20 to connect the camera module and the electronic device.
[0156] In some examples, the gap between the base 20 and the fourth side wall portion 124 can be implemented to be connected to the avoidance area 1202 located on the fourth side wall portion 124. 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 124 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.
[0157] When the avoidance area 1202 is not set on the bracket 12, the mounting structure 103 is usually respectively arranged on four parts of the bracket 12, that is, the first side wall portion 121, the second side wall portion 122, the third side wall portion 123 and the fourth side wall portion 124 are each provided with at least one mounting structure 103 to ensure a stable connection between the camera module and the electronic device. After the avoidance zone 1202 is set on the bracket 12, the installation position of the installation structure 103 on the bracket 12 is away from the avoidance zone 1202 to avoid the two from interfering with each other due to being too close. When the two are too close, the force applied to the installation 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 installation structure 103 and the adjacent parts of the bracket 12 that are too close, and may even cause the installation structure 103 to break during the fixed installation stage.
[0158] Specifically, when the avoidance area 1202 is located on the first side wall portion 121 / the third side wall portion 123 , the mounting structure 103 on the same side as the avoidance area 1202 is disposed on the first side wall portion 121 / the third side wall portion 123 .
[0159] More specifically, the avoidance area 1202 and the mounting structure 103 on the same side are not located in the same height direction (first direction Z axis), so that the mounting structure 103 avoids the avoidance area 1202 to prevent the fixed installation operation from having an adverse effect on the structural strength of the avoidance area 1202.
[0160] Furthermore, when the number of the mounting structures 103 is not greater than four, at least two of the mounting structures 103 are respectively arranged at the two end points of the diagonal of the bracket 12, or at least two of the mounting structures 103 are symmetrically arranged on the second side wall portion 122 and the third side wall portion 123, and at least one of the mounting structures 103 is arranged on the first side wall portion 121, so that the mounting 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.
[0161] In some examples, the number of the avoidance zone 1202 is one, and at least two of the mounting structures 103 are respectively disposed at two end points of a diagonal line of the bracket 12, such as Figure 8 As shown, when the avoidance area 1202 is located at the tail of the first side wall portion 121 close to the fourth side wall portion 124, one of the mounting structures 103 is arranged at the border or connecting corner between the first side wall portion 121 and the second side wall portion 122, and the other is arranged at the border or connecting corner between the third side wall portion 123 and the fourth side wall portion 124; when the avoidance area 1202 is located at the tail of the third side wall portion 123 close to the fourth side wall portion 124, one of the mounting structures 103 is arranged at the border or connecting corner between the second side wall portion 122 and the third side wall portion 123, and the other is arranged at the border or connecting corner between the first side wall portion 121 and the fourth side wall portion 124.
[0162] In some examples, the number of the avoidance zones 1202 is two, which are located at the tail of the second side wall portion 122 close to the fourth side wall portion 124 and the tail of the third side wall portion 123 close to the fourth side wall portion 124, respectively. Figure 8 As shown, at least two of the mounting structures 103 are respectively arranged on the first side wall portion 121 and the third side wall portion 123, and at least one of the mounting structures 103 is arranged on the first side wall portion 121, so as to avoid mutual interference between the mounting structure 103 and the avoidance area 1202, so as to ensure the mechanical strength of the bracket 12 and the installation stability of the camera module on the electronic device.
[0163] In some examples, at one corner of the bracket 12 or at two corners located on its diagonal line, one mounting structure 103 may be provided on both sides of each corner to further enhance the mounting stability of the camera module on the electronic device.
[0164] In one embodiment of the present application, the camera module is an upright camera module, including the shell 10 and the base 20, the shell 10 includes the cover portion 101 and the side wall portion 102 whose extended distribution planes are perpendicular to each other, a portion of the top of the side wall portion 102 and the cover portion 101 together constitute the shell 11, and the other portion of the side wall portion 102 constitutes the bracket 12, the shell 11 has a light opening 202, a portion of the lens assembly 30 extends from the receiving space 200 between the shell 10 and the base 20 in the opposite direction of the optical path, and extends out of the shell 10 through the light opening 202 of the shell 11, A buckle structure for positioning is also provided between the bracket 12 and the base 20. The positioning structure includes a matching buckle hole 1204 and a buckle 205. Figure 6-7 As shown, the bracket 12 is provided with a clamping hole 1204, and the base 20 is provided with a buckle 205, so as to further simplify the alignment and assembly between the housing 10 and the base 20. Among the four side walls of the bracket 12, at least three side walls have the clamping hole 1204.
[0165] Combined with the functions of the four side walls of the bracket 12, the first side wall portion 121 and the third side wall portion 123 parallel to the optical path are the positions for fixing the camera module by gluing, the second side wall portion 122 is suitable for positioning the prism, and the fourth side wall portion 124 corresponds to the assembly of the photosensitive component 40. Therefore, it is preferred that the first side wall portion 121, the second side wall portion 122 and the third side wall portion 123 are provided with the clamping hole 1204, and the clamping hole 1204 on the first side wall portion 121 and / or the third side wall portion 123 cooperates with the buckle 205 on the base 20 to limit the displacement of the shell 10 relative to the base 20 in the longitudinal direction (the second direction Y axis) of the light beam propagation direction; the clamping hole 1204 on the second side wall portion 122 cooperates with the buckle 205 on the base 20 to limit the displacement of the shell 10 relative to the base 20 in the transverse direction (the third direction X axis).
[0166] In some examples, the number of the latch holes 1204 located on the first side wall portion 121 / the third side wall portion 123 is not less than two. Since the avoidance area 1202 is located on the same side wall portion, the extended area after the avoidance area 1202 is removed from the first side wall portion 121 / the third side wall portion 123 is used as the distribution area of the latch holes 1204. No less than two latch holes 1204 are evenly distributed in the distribution area or symmetrically distributed in the distribution area to achieve quick alignment and assembly between the shell 10 and the base 20.
[0167] In some examples, the latch hole 1204 may be disposed on the base 20 , and the buckle 205 may be disposed on the bracket 12 .
[0168]
Circuit structure
[0169] The driving mechanism of the camera module also includes a position sensing component, which is used to sense the position of the lens assembly 30 and / or the optical path turning assembly 50 to improve the accuracy of motion position control.
