Description

Camera assembly structure and electronic equipment Technical Field

[0001] The present application relates to the technical field of cameras, and more specifically, to an assembly structure of a camera and an electronic device. Background Art

[0002] Electronic devices such as mobile phones, tablets, and smartwatches typically have a front-facing camera, which is positioned on the midframe via a front-facing camera bracket. During assembly, the front-facing camera is secured to the bracket, which is then secured to the midframe. Finally, a press-fit bracket secures the camera, bracket, and midframe together.

[0003] Because the front camera bracket has a shell-like structure, part of the thickness space between the front camera and the middle frame is occupied by the front camera bracket. In addition, the press-fit bracket also occupies part of the thickness space, which causes the overall assembly structure of the front camera to occupy a large space in the thickness direction. It not only squeezes the installation space of other components, but also cannot meet the development needs of increasingly thin and light smartphones.

[0004] Summary of the Invention

[0005] The purpose of this application is to provide a camera assembly structure and electronic equipment, and to improve the shape structure of the camera bracket, as well as the connection method of the camera body, camera bracket, and middle frame, so that the overall thickness of the camera assembly structure is reduced, avoiding excessive occupation of the internal space of the electronic device, and meeting the development needs of lighter and thinner electronic equipment.

[0006] In a first aspect, the present application provides an assembly structure of a camera, including a camera body, a camera bracket and a middle frame.

[0007] The camera body comprises a shell, a lens and a mounting portion arranged on two opposite sides of the shell, and an edge of the mounting portion extends out of the shell.

[0008] The camera bracket is a ring-shaped frame structure, and the middle part of the camera bracket is hollowed out.

[0009] The middle frame is provided with a avoidance hole for avoiding the lens.

[0010] The mounting portion, the camera bracket and the middle frame are stacked and connected in sequence. The outer shell is located in the hollow part of the camera bracket, and the lens is located in the avoidance hole.

[0011] The assembly structure of the camera in the present application, by designing the camera bracket into a ring-shaped frame structure, the outer shell of the camera body can be completely placed in the hollow part of the camera bracket, so that the outer shell and the middle frame are directly opposite to each other, avoiding the camera bracket being sandwiched between the outer shell and the middle frame to increase the overall thickness of the assembly structure; by providing an extended mounting portion at the bottom of the outer shell, the mounting portion can be directly connected to the camera bracket. After the camera bracket is connected to the middle frame, the mounting portion can form a pressing cover effect, so that the outer shell and the lens are pressed and fixed on the middle frame, which can eliminate the pressing bracket in the related art, thereby reducing the overall thickness of the assembly structure.

[0012] In summary, the assembly structure of the camera in the embodiment of the present application is improved with respect to the shape structure of the camera bracket, as well as the connection method among the camera body, the camera bracket and the middle frame, so that the overall thickness of the camera assembly structure is reduced, thereby avoiding excessive occupation of the internal space of the electronic device and meeting the development demand of lighter and thinner electronic devices.

[0013] In one possible design, the camera bracket is bonded to the mounting portion.

[0014] By fixing the camera bracket and the mounting part by bonding, there is no need to design a connection structure on the camera bracket and the mounting part. It has the advantages of simple structure, easy processing, and low assembly cost. In addition, the appearance of the camera bracket and the mounting part after bonding is consistent, and there are no screws or other connecting parts protruding from the surface.

[0015] In one possible design, a glue groove is provided on a side of the camera bracket opposite to the mounting portion, and the glue groove is filled with adhesive.

[0016] The adhesive groove can control the filling amount of the adhesive, thereby ensuring the bonding strength between the camera bracket and the mounting part, while also preventing the adhesive 40 from overflowing, thereby reducing the difficulty of assembly implementation.

[0017] In one possible design, the camera bracket is bonded to the middle frame.

[0018] Fixing the camera bracket and the middle frame by bonding has the advantages of simple structure, easy processing, and low assembly cost. In addition, the appearance of the camera bracket and the middle frame after bonding is consistent, and there are no screws or other connecting parts protruding from the surface.

[0019] In one possible design, a support structure is provided on the side of the camera bracket opposite to the middle frame, and the support structure is used to support the opposite surfaces of the camera bracket and the middle frame to form a glue space, and the glue space is filled with adhesive.

[0020] It can prevent the adhesive between the camera bracket and the middle frame from being squeezed out, thereby preventing the adhesive from overflowing and reducing the difficulty of assembly implementation.

[0021] In a possible design, the supporting structure includes a boss that is annular and arranged along an edge of the hollow portion.

[0022] The support structure designed in this way has four main functions: first, it is used to support the opposite surfaces of the camera bracket and the middle frame to form a glue-containing space; second, it is arranged along the edge of the hollow part, which can form the largest glue-containing space compared to other positions, and thus has a larger amount of adhesive dispensing, thereby ensuring the bonding strength between the camera bracket and the middle frame; third, the glue-containing space supported by the annular boss is also annular on the surface of the middle frame, and the adhesive filled is also annular, so that the adhesive also forms an effect similar to an annular sealing ring, which can play a waterproof sealing role; fourth, the annular boss can also block the glue, which can prevent the adhesive from overflowing toward the avoidance hole of the middle frame.

[0023] In one possible design, the outer shell is connected to the middle frame.

[0024] This enables the middle frame to establish a direct connection with the camera body, thereby further improving the connection strength between the camera body, camera bracket and middle frame, making the three as a whole structure reliable and highly shock-resistant.

[0025] In a possible design, the area of ​​the housing adjacent to the lens and the area of ​​the middle frame adjacent to the avoidance hole are sealedly connected via an annular sealing member.

[0026] It can play a good waterproof sealing role and prevent external liquid from entering the interior of the camera body through the avoidance hole.

[0027] In one possible design, there is a gap between the inner peripheral side wall of the camera bracket and the outer peripheral side wall of the shell, and a filling piece is provided in the gap to tighten the shell and the camera bracket.

[0028] The outer shell and the camera bracket can be positioned by the filling piece, which can reduce the processing difficulty of the camera bracket and reduce the manufacturing cost of the camera bracket.

[0029] In a possible design, the filling piece is formed by a supporting block provided on the inner peripheral side wall of the camera bracket.

[0030] The filling piece is formed by the supporting block on the inner peripheral side wall of the camera bracket, and there is no need to install the filling piece separately, so that the camera bracket and the supporting block can be assembled with the camera bracket as a whole, thereby reducing the difficulty of assembly.

[0031] In one possible design, the camera bracket has a rectangular cutout, and the housing is shaped like the cutout;

[0032] The camera body also includes a flexible transmission component, the shell has a first side wall and a second side wall that are orthogonal to each other, the flexible transmission component is located on the side of the shell facing the first side wall, and the supporting block is located on the inner peripheral side wall of the camera bracket facing the second side wall.

[0033] The supporting block is only provided on the inner peripheral side wall of one side of the camera bracket, so that the housing and the camera bracket can be accurately positioned, which can save the material cost for forming the supporting block and reduce the manufacturing difficulty and cost of the camera bracket.

[0034] In a possible design, an end of the supporting block facing the mounting portion is provided with a chamfered surface.

[0035] In the initial stage of placing the shell into the hollow part of the camera bracket, the elastic reset force of the flexible transmission part will not be affected, so that the shell has a certain lowering margin in the hollow part, which can meet the positioning of the shell by the flexible transmission part; in addition, the beveled surface also has a chamfering effect, so that the shell can be smoother during the lowering process, and the shell is easier to be installed into the hollow part of the camera bracket.

[0036] In one possible design, the gap is filled with adhesive.

[0037] The outer shell is also bonded and fixed to the camera bracket by adhesive, which can further improve the connection strength between the camera body and the camera bracket, thereby further improving the connection strength between the camera body, the camera bracket and the middle frame, making the three as a whole structure with reliable strength.

[0038] In one possible design, the mounting portion and the camera bracket are provided with an anti-fouling mechanism.

[0039] When assembling the camera body and the camera bracket, the assembly efficiency and accuracy can be improved.

[0040] In a possible design, there are three notches at the corners of the mounting portion, and the camera bracket is provided with bosses at positions corresponding to the three notches, and the notches and the bosses form an anti-fool mechanism.

[0041] In one possible design, the camera body includes a substrate, and the mounting portion is formed by the substrate.

[0042] By reusing the substrate to form the mounting portion, the processing cost of the mounting portion is reduced, there is no need to set up a separate mounting portion, and the overall structure of the camera body can be made compact.

[0043] In one possible design, the camera body includes a filter holder, and the mounting portion is formed by the filter holder.

[0044] By reusing the filter bracket to form the mounting portion, the processing cost of the mounting portion is reduced, there is no need to set up a separate mounting portion, and the overall structure of the camera body can be made compact.

[0045] In a second aspect, the present application also provides an electronic device comprising an assembly structure of any of the above-mentioned cameras.

[0046] The assembly structure of the camera in this application is improved with respect to the shape structure of the camera bracket, as well as the connection method among the camera body, the camera bracket and the middle frame, so that the overall thickness of the camera assembly structure is reduced, thereby avoiding excessive occupation of the internal space of the electronic device and meeting the development demand of lighter and thinner electronic devices.

DETAILED DESCRIPTION

[0064] The following is an illustrative introduction to the relevant contents that may be involved in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments.

[0065] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or mutual communication; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0066] In the description of this application, it should be understood that the terms "upper", "lower", "side", "inside", "outside", "top", "bottom", etc. indicate orientations or positional relationships based on the installation, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0067] It should also be noted that, in the embodiments of the present application, the same reference numerals are used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or parts as an example. It should be understood that the reference numerals are also applicable to other identical parts or parts.

[0068] In the description of this application, it should be noted that the term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone.

[0069] Fig. 1 is a schematic diagram of a smartphone in the related art. Fig. 2 is a cross-sectional view taken along line AA in Fig. 1 .

[0070] As shown in Figures 1 and 2, in related art, the front camera 400 is typically secured within the installation space enclosed by the display screen 100 and the battery cover 200 by components such as the front camera bracket 500 and the middle frame 20. Specifically, when assembling the front camera 400 of a smartphone, the front camera 400 is first secured to the front camera bracket 500, then the front camera bracket 500 is secured to the middle frame 20, and finally, the front camera 400, front camera bracket 500, and middle frame 20 are pressed together using the pressing bracket 300.

[0071] Since the front camera bracket 500 in the related art is a shell-like structure, it will occupy a part of the space in the thickness direction. For example, as shown in the position indicated by B in Figure 2, there is a front camera bracket 500 between the front camera 400 and the middle frame 20, so that the front camera bracket 500 occupies a part of the thickness space. In addition, the press-fit bracket 300 also occupies a part of the thickness space, which causes the overall assembly structure of the front camera 400 to occupy a large space in the thickness direction, which not only squeezes the installation position of other components, but also fails to meet the development demand of increasingly thin and light smartphones.

[0072] In view of this, in order to solve the above-mentioned technical problems, the present application provides a camera assembly structure and electronic equipment, which improves the shape structure of the camera bracket, as well as the connection method of the camera body, the camera bracket and the middle frame, so that the overall thickness of the camera assembly structure is reduced, avoiding excessive occupation of the internal space of the electronic device, and meeting the development needs of lighter and thinner electronic devices.

[0073] The present application first provides an electronic device, which may also be referred to as a mobile device, terminal device, mobile terminal, or terminal. The electronic device includes, but is not limited to, a handheld device, an in-vehicle device, a wearable device, a computing device, or other processing device connected to a wireless modem. For example, the electronic device may include a smart watch, a smart wristband, a smart phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, an in-vehicle computer, smart glasses, a handheld game console, and other electronic devices that have a camera and require a camera assembly structure to achieve a lightweight design.

[0074] In order to more conveniently explain the electronic device provided in the embodiment of the present application, as an example rather than a limitation, the following will take the electronic device being a smart phone as an example to explain in detail the technical solution of the present application.

[0075] The smartphone provided in an embodiment of the present application includes a display screen 100, a housing, and a camera body 10. The housing further includes a middle frame 20 and a battery cover 200. The display screen 100 is fixed to the front face of the middle frame 20, and the battery cover 200 is fixed to the rear face of the middle frame 20. The display screen 100, the middle frame 20, and the battery cover 200 together define a housing space for the smartphone, which is used to install various functional components of the smartphone, such as the camera body 10 described in the embodiments below, as well as other functional components such as the battery, microphone, and processor.

[0076] Optionally, the battery cover 200 can be screwed or snapped onto the middle frame 20, and a sealing ring can be provided between the battery cover 200 and the middle frame 20 to improve the sealing and waterproof effect at the junction of the battery cover 200 and the middle frame 20. The sealing ring can be made of a highly elastic material such as silicone or rubber.

[0077] Optionally, the camera body 10 can be a rear camera or a front camera. Therefore, the camera assembly structure in this application can be used for rear camera assembly or front camera assembly.

[0078] Since the high-magnification zoom of the rear cameras of smartphones currently on the market is basically "jump-type" zoom, that is, hybrid optical zoom is achieved by equipping two or more lenses with different focal lengths12 with algorithm-based digital zoom.

[0079] Therefore, the number of camera bodies 10 installed is not limited to one, and can also be two or even more, for example, four rear cameras are installed on the back of a smartphone. That is, the embodiment of the present application does not impose any limitation on the number of camera bodies 10 installed.

[0080] In order not to affect the appearance of the smartphone and to protect the camera, the smartphone further includes a camera decoration (Deco), which is a hollow shell-shaped decoration made of metal or plastic.

[0081] In addition, a smartphone may also include functional components such as a processor, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, a microphone, a mobile communication module, an antenna, a wireless communication module, an audio module, a headphone interface, a sensor module, buttons, and a subscriber identification module (SIM) card interface.

[0082] These functional elements can be changed according to user needs. It can be understood that the specific embodiment introduced above is only a specific implementation method of the present application. Other ways to implement the solution of the present application are also within the scope of protection of the present application and will not be described in detail here.

[0083] The assembly structure of the camera provided in this application is now described in detail with reference to the accompanying drawings.

[0084] Figure 3 is a schematic diagram of the assembly structure of a camera provided in an embodiment of the present application. Figure 4 is an exploded view of the assembly structure of the camera in Figure 3. Figure 5 is an exploded view of the assembly structure of the camera in Figure 3 from another perspective.

[0085] As shown in FIG3-FIG5 , an embodiment of the present application provides an assembly structure of a camera, including a camera body 10 , a middle frame 20 and a camera bracket 30 .

[0086] The camera body 10 includes a housing 11 , and lenses 12 and a mounting portion 13 disposed on opposite sides of the housing 11 . The edge of the mounting portion 13 extends out of the housing 11 .

[0087] The camera bracket 30 is an annular frame structure, and the middle part of the camera bracket 30 is hollow.

[0088] The middle frame 20 is provided with a relief hole 21 for evading the lens 12 .

[0089] The mounting portion 13 of the camera body 10 , the camera bracket 30 and the middle frame 20 are stacked and connected in sequence. The housing 11 is located in the hollow portion 31 of the camera bracket 30 , and the lens 12 is located in the avoidance hole 21 .

[0090] The assembly structure of the camera in the embodiment of the present application, by designing the camera bracket 30 as a ring-shaped frame structure, the shell 11 of the camera body 10 can be completely placed in the hollow part 31 of the camera bracket 30, so that the shell 11 and the middle frame 20 are directly opposite to each other, avoiding the camera bracket 30 being sandwiched between the shell 11 and the middle frame 20 to increase the overall thickness of the assembly structure; by providing an extended mounting portion 13 at the bottom of the shell 11, the mounting portion 13 can be directly connected to the camera bracket 30. After the camera bracket 30 is connected to the middle frame 20, the mounting portion 13 can form a pressure cover effect, so that the shell 11 and the lens 12 are pressed and fixed on the middle frame 20, and the pressing bracket 300 in the related art can be omitted, thereby reducing the overall thickness of the assembly structure.

[0091] In summary, the assembly structure of the camera in the embodiment of the present application is improved with respect to the shape structure of the camera bracket 30, as well as the connection method among the camera body 10, the camera bracket 30, and the middle frame 20, so that the overall thickness of the camera assembly structure is reduced, thereby avoiding excessive occupation of the internal space of the smartphone, and being able to meet the development demand for thinner and lighter smartphones.

[0092] Fig. 6 is a schematic diagram of the camera body 10 provided in an embodiment of the present application. Fig. 7 is a schematic diagram of the camera body 10 in Fig. 6 from another perspective.

[0093] As shown in Figures 6 and 7, in an embodiment provided in the present application, in addition to the housing 11, the lens 12 and the mounting portion 13, the camera body 10 also includes a substrate 14, a photosensitive chip, a filter holder 15, a filter, a flexible transmission component 16, a connector 17, etc.

[0094] The lens 12 is used to send outgoing light to the photosensitive chip, that is, to form a light signal of the subject and reflect it to the photosensitive chip. Among them, the lens 12 can be composed of multiple spherical or aspherical lenses with optical properties.

[0095] The photosensitive chip can be installed on the substrate 14, or it can be installed on the bracket of other components. The photosensitive chip is used to receive the output light of the lens 12, that is, the photosensitive chip is used to perform photoelectric conversion and analog signal / digital signal (Analog / Digital, A / D) conversion on the light signal corresponding to the subject, thereby outputting image data for display on a display unit such as the display screen 100.

[0096] Optionally, the photosensitive chip includes but is not limited to a complementary metal oxide semiconductor (CMOS) image sensor or a charge coupled device (CCD) image sensor.

[0097] The substrate 14 may be a printed circuit board (PCB). Alternatively, the substrate 14 may be made of direct bond ceramic (DBC), active metal brazing (AMB), or direct bond aluminum (DBA).

[0098] The filter is placed between the lens 12 and the photosensitive chip. The main function of this filter is to filter out some stray light such as infrared light and visible red light, which can further improve the image quality of the lens 12 on the photosensitive chip. The filter can be a blue glass (GB) filter.

[0099] The filter holder 15 is arranged between the substrate 14 and the housing 11. A light hole is provided in the middle of the filter holder 15. On the side close to the lens 12, the opening of the light hole is recessed inward to form a groove, and the filter is fixed in the groove.

[0100] The housing 11 is connected to the filter holder 15, and together they define a housing space, which can be used to install a lens holder, a focusing mechanism, an anti-shake mechanism, etc. The housing 11 is also provided with a hole for avoiding the lens 12, and the lens 12 extends outward from the hole.

[0101] The flexible transmission member 16 is connected between the substrate 14 and the connector 17. The connector 17 is used to connect to the motherboard of the smartphone, thereby establishing a communication route among the substrate 14, the flexible transmission member 16, the connector 17, and the motherboard, so that the battery of the smartphone can power the camera body 10. A system-on-chip (SoC) is provided on the motherboard, and the shooting function of the camera body 10 can be controlled by the SoC chip. In addition, the camera body 10 can transmit the captured images or video data to the SoC chip.

[0102] Optionally, the flexible transmission member 16 can be any one of an electric wire, a bare wire, a flexible flat cable (FFC), and a flexible printed circuit (FPC); or, the flexible transmission member 16 can also be a combination of at least two of an electric wire, a bare wire, a flexible flat cable, and a flexible printed circuit.

[0103] Specifically, the wires in the embodiments of the present application refer to conventional wires, which are composed of conductors and insulation layers, wherein the conductors include various metals such as copper and aluminum and composite metal round single wires, and the conductors are wrapped with rubber, plastic and other non-metallic insulation layers.

[0104] Specifically, the bare wire in the embodiment of the present application refers to a product having only a conductor but no insulation layer, and only includes various metals such as copper, aluminum, and composite metal round single wires.

[0105] Specifically, the flexible flat cable in the embodiment of the present application can arbitrarily select the number and spacing of conductors, making wiring more convenient. It is most suitable for use as a data transmission cable between two printed circuit boards and in miniaturized electrical equipment.

[0106] Specifically, the flexible circuit board in the embodiment of the present application is a highly reliable and excellently flexible circuit board made of polyimide or polyester film as a base material.

[0107] Whether it is a bare wire, a conventional wire, a flexible flat cable or a flexible circuit board, it has bendable flexibility. During the assembly stage of the camera body 10, after the connector 17 is assembled to the main board, the flexible transmission part 16 will not restrict the position movement of the substrate 14 and the shell 11, so that the shell 11 can be freely adjusted on the camera bracket 30, thereby reducing the difficulty of assembling the camera body 10.

[0108] Optionally, the connector 17 may be a zero insertion force connector (ZIF), a wire-to-board connector (WTB), a board-to-board connector (BTB), or the like.

[0109] Specifically, the zero insertion force connector in the embodiment of the present application is characterized in that no forced insertion force is required during connection, but a smooth connection is achieved by loosening the buckle.

[0110] Specifically, the wire-to-board connector in the embodiment of the present application is a connector that connects wires to a circuit board.

[0111] Specifically, the board-to-board connector in the embodiment of the present application has the advantages of high precision and small size, supports large current or dense pins, and has strong transmission capability.

[0112] As mentioned above, the camera body 10 has a mounting portion 13 extending from the bottom of the housing 11, which allows the mounting portion 13 to be directly connected to the camera bracket 30. After the camera bracket 30 is connected to the middle frame 20, the mounting portion 13 forms a pressure-locking effect, firmly securing the housing 11 and lens 12 to the middle frame 20, eliminating the need for the press-fit bracket 300 used in related art. The mounting portion 13 can be a separate component added to the camera body 10; alternatively, it can be formed by reusing the filter bracket 15 or the substrate 14, as described in the following embodiments.

[0113] As shown in FIG. 6 and FIG. 7 , in an embodiment provided in the present application, the mounting portion 13 is formed by a filter holder 15 .

[0114] In this embodiment, the filter holder 15 is reused to form the mounting portion 13 , thereby reducing the processing cost of the mounting portion 13 , eliminating the need to separately provide the mounting portion 13 , and enabling the overall structure of the camera body 10 to be compact.

[0115] In another embodiment provided in the present application, the mounting portion 13 is formed by a substrate 14 .

[0116] In this embodiment, the mounting portion 13 is formed by reusing the substrate 14 , thereby reducing the processing cost of the mounting portion 13 , eliminating the need to separately provide the mounting portion 13 , and enabling the overall structure of the camera body 10 to be compact.

[0117] Optionally, when the mounting portion 13 of the camera body 10 is fixedly connected to the camera bracket 30, they can be bonded by adhesive 40, or locked by screws, or plugged by a socket structure, or snapped by a snap structure, or a groove can be opened on the opposite surface of the camera bracket 30 and the mounting portion 13, and the mounting portion 13 can be embedded and fixed in the groove.

[0118] In an embodiment provided in the present application, the camera bracket 30 is bonded to the mounting portion 13 .

[0119] In this embodiment, the camera bracket 30 and the mounting part 13 are fixed by bonding. Compared with screw locking, socket structure insertion, snap structure clamping and other methods, there is no need to design a connection structure between the camera bracket 30 and the mounting part 13. It has the advantages of simple structure, easy processing, and low assembly cost. In addition, the appearance of the camera bracket 30 and the mounting part 13 after bonding is more consistent, and there will be no screws or other connecting parts protruding from the surface.

[0120] Fig. 8 is a schematic diagram of the camera bracket 30 provided in an embodiment of the present application. Fig. 9 is a schematic diagram of the camera bracket 30 in Fig. 8 from another perspective.

[0121] As shown in FIG. 8 and FIG. 9 , in an embodiment provided in the present application, a glue groove 32 is provided on a side of the camera bracket 30 opposite to the mounting portion 13 , and the glue groove 32 is filled with adhesive 40 .

[0122] In this embodiment, the filling amount of the adhesive 40 can be controlled by designing the adhesive groove 32, thereby ensuring the bonding strength between the camera bracket 30 and the mounting portion 13, while also preventing the adhesive 40 from overflowing, thereby reducing the difficulty of assembly implementation.

[0123] Optionally, the adhesive 40 may be a light-curing adhesive, such as an ultraviolet (UV) curing adhesive. The UV curing adhesive is also called shadowless adhesive or photosensitive adhesive, which refers to a type of adhesive that must be cured by ultraviolet light.

[0124] Optionally, the adhesive 40 may also be a heat-curing adhesive, such as polyurethane adhesive, which is an adhesive that is cured by a heat source, has good stability, produces no by-products after curing, and has good bonding strength and sealing properties.

[0125] Optionally, when the camera bracket 30 is fixedly connected to the middle frame 20, it can be bonded by adhesive 40, or locked by screws, or plugged by a socket structure, or snapped by a snap structure, or grooves can be opened on the opposite surfaces of the middle frame 20 and the camera bracket 30, and the camera bracket 30 can be embedded and fixed in the groove.

[0126] In one embodiment provided in the present application, the camera bracket 30 is bonded to the middle frame 20 .

[0127] In this embodiment, the camera bracket 30 and the middle frame 20 are fixed by bonding, which has the advantages of simple structure, easy processing, and low assembly cost compared with screw locking, socket structure insertion, and snap structure clamping. In addition, the appearance of the camera bracket 30 and the middle frame 20 after bonding is more consistent, and there are no screws or other connecting parts protruding from the surface.

[0128] Figure 10 is a cross-sectional view of the assembly structure of the camera provided in an embodiment of the present application. Figure 11 is a cross-sectional view of the assembly structure of the camera provided in an embodiment of the present application from another perspective.

[0129] As shown in Figures 10-11, and again as shown in Figure 9, in an embodiment provided in the present application, a support structure 33 is provided on the side of the camera bracket 30 opposite to the middle frame 20, and the support structure 33 is used to support the opposite surfaces of the camera bracket 30 and the middle frame 20 to form a glue space, and the glue space is filled with adhesive 40.

[0130] In this embodiment, the support structure 33 is designed to support the adhesive space, which can prevent the adhesive 40 between the camera bracket 30 and the middle frame 20 from being squeezed out, thereby preventing the adhesive 40 from overflowing, and reducing the difficulty of assembly implementation.

[0131] Optionally, the support structure 33 may be a convex point, and the shape of the convex point includes one or more of a hemisphere, a cylinder, a truncated cone, a prism, and a pyramid.

[0132] As shown in FIG. 9 , in one embodiment provided in the present application, the support structure 33 includes a boss 331 . The boss 331 is annular and arranged along the edge of the hollow portion 31 .

[0133] In this embodiment, the support structure 33 is an annular boss 331, and the annular boss 331 is arranged along the edge of the hollow part 31. The support structure 33 designed in this way has four main functions: first, it is used to open the opposite surfaces of the camera bracket 30 and the middle frame 20 to form a glue-containing space; second, it is arranged along the edge of the hollow part 31. Compared with being arranged in other positions, it can form the largest glue-containing space, and thus have a larger amount of glue 40, thereby ensuring the bonding strength between the camera bracket 30 and the middle frame 20; third, the glue-containing space opened by the annular boss 331 is also annular on the surface of the middle frame 20, and then the filled adhesive 40 is also annular, such as the case shown in Figure 4, so that the adhesive 40 also forms an effect similar to an annular sealing ring, which can play a waterproof sealing role; fourth, the annular boss 331 can also block glue, which can prevent the adhesive 40 from overflowing toward the avoidance hole 21 of the middle frame 20.

[0134] In an embodiment provided in the present application, the outer shell 11 is connected to the middle frame 20 .

[0135] In this embodiment, the outer shell 11 is connected to the middle frame 20, so that the middle frame 20 and the camera body 10 can establish a direct connection relationship, thereby further improving the connection strength between the camera body 10, the camera bracket 30, and the middle frame 20, so that the three as an integral structure have reliable strength and strong shock resistance.

[0136] Optionally, when the shell 11 and the middle frame 20 are fixedly connected, they can be bonded by an adhesive 40, or locked by screws, or plugged by a socket structure, or snapped by a snap structure.

[0137] As shown in Figures 10-11 and Figure 5, in one embodiment provided in the present application, the area of ​​the housing 11 adjacent to the lens 12 and the area of ​​the middle frame 20 adjacent to the avoidance hole 21 are sealed via an annular seal 22.

[0138] The seal 22 can be fixed between the outer shell 11 and the middle frame 20 by bonding, which can provide a good waterproof sealing effect and prevent external liquid from entering the interior of the camera body 10 through the avoidance hole 21.

[0139] Optionally, the sealing member 22 may be made of rubber, resin, foam, elastomer, etc.

[0140] Optionally, the seal 22 can also be directly formed by the adhesive 40, so that the boss 331 has two functions: one is to open up a space for glue between the camera bracket 30 and the middle frame 20; the other is to open up a space for glue between the shell 11 and the middle frame 20.

[0141] FIG12 is a schematic diagram of an assembly example of the camera bracket 30 and the camera body 10 provided in an embodiment of the present application.

[0142] As shown in FIG12 , in one embodiment provided in the present application, there is a gap 35 between the inner peripheral side wall of the camera bracket 30 and the outer peripheral side wall of the housing 11 , and a filling piece 36 is provided in the gap 35 to tighten the housing 11 and the camera bracket 30 .

[0143] Ideally, there is no gap 35 between the inner circumferential sidewall of the camera bracket 30 and the outer circumferential sidewall of the housing 11. However, this requires that the hollow portion 31 of the camera bracket 30 be completely compatible with the dimensions of the housing 11, which in turn places high demands on the processing precision of the camera bracket 30, thereby increasing the processing difficulty and manufacturing cost of the camera bracket 30. Therefore, in order to reduce the processing difficulty and manufacturing cost of the camera bracket 30, a slightly larger hollow portion 31 can be roughly formed in the camera bracket 30, which does not need to completely match the dimensions of the housing 11. In this way, after the housing 11 is placed in the hollow portion 31 of the camera bracket 30, a gap 35 will exist between the two. Therefore, a filler 36 is used to fill the gap 35 to tighten the housing 11 and the camera bracket 30, thereby achieving the positioning of the housing 11 and the camera bracket 30.

[0144] FIG13 is a schematic diagram of another example of assembly of the camera bracket 30 and the camera body 10 provided in an embodiment of the present application.

[0145] As shown in FIG. 13 , in one embodiment provided in the present application, the gap 35 is filled with adhesive 40 .

[0146] In this embodiment, in addition to tightening the outer shell 11 and the camera bracket 30 through the filling piece 36, the outer shell 11 and the camera bracket 30 are also bonded and fixed by the adhesive 40, which can further improve the connection strength between the camera body 10 and the camera bracket 30, thereby further improving the connection strength between the camera body 10, the camera bracket 30, and the middle frame 20, so that the strength of the three as a whole structure is reliable.

[0147] Optionally, the filling member 36 may be made of rubber, resin, foam, elastomer, etc.

[0148] Optionally, the hollow portion 31 of the camera body 10 may be circular, for example, as shown in FIG. 12 and FIG. 13 .

[0149] Optionally, the hollow portion 31 of the camera body 10 may also be rectangular, which will be described in detail in the embodiments described below.

[0150] FIG14 is a schematic diagram of an exploded view of the camera bracket 30 and the camera body 10 provided in an embodiment of the present application.

[0151] As shown in FIG. 14 , in one embodiment provided in the present application, the filling piece 36 is formed by a supporting block 361 provided on the inner peripheral side wall of the camera bracket 30 .

[0152] In this embodiment, the filling piece 36 is formed by the supporting block 361 on the inner peripheral side wall of the camera bracket 30. There is no need to install the filling piece 36 separately, so that the camera bracket 30 and the supporting block 361 are assembled with the camera bracket 30 as a whole, thereby reducing the difficulty of assembly.

[0153] Optionally, the supporting blocks 361 may be provided along the inner peripheral side wall of the camera bracket 30 .

[0154] FIG15 is a schematic diagram of the assembly of the camera bracket 30 and the camera body 10 in FIG14 .

[0155] As shown in FIG15 and further in FIG14 , in one embodiment provided herein, the hollow portion 31 of the camera bracket 30 is rectangular, and the housing 11 is shaped similarly to the hollow portion 31. The camera body 10 further includes a flexible transmission member 16. The housing 11 has a first sidewall 111 and a second sidewall 112 that are orthogonal to each other. The flexible transmission member 16 is located on the side of the housing 11 facing the first sidewall 111. The abutment block 361 is located on the inner peripheral sidewall of the camera bracket 30 facing the second sidewall 112.

[0156] In addition to being flexible, the flexible transmission member 16 also has a certain elastic reset capability. When the connector 17 is connected to the motherboard, the flexible transmission member 16 is bent and deformed to align the housing 11 with the hollow portion 31 of the camera bracket 30. When the housing 11 is then placed inside the camera bracket 30, the flexible transmission member 16 naturally expands and resets, causing the housing 11 to abut against the inner sidewall of the camera bracket 30. In this way, the flexible transmission member 16 effectively forms a single-sided positioning of the housing 11 inside the camera bracket 30. In FIG. 15 , the sidewall of the housing 11 facing away from the first sidewall 111 abuts and is positioned against the camera bracket 30. The second sidewall 112 of the housing 11 abuts against the abutting block 361, causing the sidewall of the housing 11 facing away from the second sidewall 112 to abut and be positioned against the camera bracket 30. In this way, by cooperating with the single-sided support block 361 and the elastic reset ability of the flexible transmission member 16, the housing 11 can be accurately positioned in the hollow portion 31 of the camera bracket 30.

[0157] For a better understanding, the dynamic assembly process will be described in detail below with reference to the accompanying drawings.

[0158] As shown in FIG14 , when the camera body 10 is mounted downwardly on the camera bracket 30 along the Z direction, the connector 17 is first connected to the mainboard, the flexible transmission member 16 is bent and deformed through the shell 11, and then the shell 11 is placed in the hollow portion 31 of the camera bracket 30. At this time, the flexible transmission member 16 will naturally expand and push the shell 11 in the X direction, so that the shell 11 abuts against the camera bracket 30 in the X direction; then the shell 11 is pressed down further, so that the shell 11 contacts the abutting block 361, and in the process of gradually pressing down the shell 11, the abutting block 361 will gradually push the shell 11 in the Y direction, so that the shell 11 abuts against the camera bracket 30 in the Y direction; as shown in FIG15 , finally, the shell 11 is accurately positioned in the X and Y directions at the hollow portion 31 of the camera bracket 30, thereby accurately positioning the lens 12 on the camera bracket 30, paving the way for the accurate positioning of the lens 12 and the avoidance hole 21 in the subsequent assembly process.

[0159] In this embodiment, the supporting block 361 is only provided on the inner peripheral side wall of one side of the camera bracket 30 , which can save the material cost for forming the supporting block 361 and reduce the manufacturing difficulty and cost of the camera bracket 30 .

[0160] Optionally, in order to prevent the housing 11 from deflecting, at least two abutting blocks 361 are arranged on the inner peripheral side wall of the camera bracket 30 opposite to the second side wall 112 .

[0161] As mentioned above, in the process of gradually pressing down the housing 11, the abutting block 361 will gradually push the housing 11 in the Y direction. In the initial stage of placing the housing 11 into the hollow portion 31 of the camera bracket 30, the abutting block 361 does not push the housing 11 until it abuts against the camera bracket 30. This is to prevent the abutting block 361 from generating excessive friction and affecting the elastic restoring force of the flexible transmission member 16, thereby preventing the flexible transmission member 16 from being unable to push the housing 11 in the Y direction. To achieve this effect, the upper edge of the abutting block 361 can be designed to have a height difference with the upper edge of the camera bracket 30, that is, the upper edge of the abutting block 361 is lower than the upper edge of the camera bracket 30, or it can also be implemented as in the design scheme of the following embodiment.

[0162] As shown in FIG. 14 , in one embodiment provided in the present application, a chamfered surface 362 is provided at the end of the supporting block 361 facing the mounting portion 13 .

[0163] In this embodiment, by designing a bevel surface 362 on the supporting block 361, the shell 11 can be placed in the hollow part 31 of the camera bracket 30 in the initial stage without affecting the elastic reset force of the flexible transmission component 16, so that the shell 11 has a certain lowering margin in the hollow part 31, which can meet the positioning of the shell 11 in the X direction by the flexible transmission component 16; in addition, the bevel surface 362 also has a chamfering effect, so that the shell 11 can be smoother during the descending process, and the shell 11 is easier to be installed in the hollow part 31 of the camera bracket 30.

[0164] FIG16 is a schematic diagram of another example of assembly of the camera bracket 30 and the camera body 10 provided in an embodiment of the present application.

[0165] As shown in Figure 16, in an embodiment provided in the present application, an adhesive 40 is filled in the gap 35, so that the housing 11 and the camera bracket 30 can be tightened by the supporting block 361 while also being able to establish a further bonding relationship to improve the connection strength between the camera body 10 and the camera bracket 30.

[0166] In an embodiment provided in the present application, the mounting portion 13 and the camera bracket 30 are provided with an anti-fool mechanism 50 .

[0167] In this embodiment, the mounting portion 13 and the camera bracket 30 are provided with a fool-proof mechanism 50 , which can improve assembly efficiency and accuracy when the camera body 10 and the camera bracket 30 are assembled.

[0168] Optionally, the foolproof mechanism 50 can be a pin and a slot, a bump and a groove, etc. respectively provided on the camera body 10 and the camera bracket 30.

[0169] As shown in Figures 6 and 8, in an embodiment provided in the present application, there are three notches 131 at the corners of the mounting portion 13, and the camera bracket 30 is respectively provided with bosses 37 at the positions corresponding to the three notches 131. The notches 131 and the bosses 37 form an anti-mistake mechanism 50.

[0170] Finally, it should be noted that the above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
