Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to an electronic device and a circuit board assembly. Background Technology

[0002] With the advancement of technology, electronic devices are becoming increasingly functional, and cameras are an indispensable component. A camera is a component in electronic devices used to capture images and convert light signals into corresponding electrical signals.

[0003] Typically, to install a camera, a certain amount of space needs to be reserved on a printed circuit board (PCB), and a specific bracket needs to be set up in the reserved space to fix the camera.

[0004] However, brackets take up space on the circuit board that is used to house other electronic components, resulting in low space utilization of the circuit board. Utility Model Content

[0005] This application provides an electronic device and a circuit board assembly that can solve the problem of low space utilization in existing circuit boards.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, this application provides an electronic device, including: a circuit board, a bracket, a fixing member, and a camera assembly; a connector is disposed on the circuit board; the bracket is disposed on the circuit board, at least a portion of the bracket being located on the side of the connector opposite to the circuit board; the fixing member is disposed on the side of the bracket opposite to the circuit board, and the fixing member is connected to the bracket; the camera assembly is located on the side of the fixing member opposite to the circuit board, and the camera assembly is disposed on the fixing member.

[0008] The bracket can secure the connector. By utilizing the structural characteristics of this bracket, the camera assembly is mounted on the side of the bracket away from the circuit board via a fastener, effectively securing the camera assembly. Since there is no need for a separate bracket specifically for securing the camera assembly, it does not occupy space on the circuit board used for other electronic components, thereby increasing the effective area of ​​the circuit board available for electronic components and improving the space utilization rate of the circuit board.

[0009] In one possible implementation, at least a portion of the bracket contacts the side of the connector away from the circuit board to limit the displacement of the connector in the thickness direction of the circuit board.

[0010] By making at least a portion of the bracket contact the side of the connector away from the circuit board, the displacement of the connector in the thickness direction of the circuit board can be further restricted, thereby enhancing the stability of the connector connection and preventing connection loosening or signal interruption caused by external forces.

[0011] In one possible implementation, the fastener includes a connected support plate and a first protrusion, the support plate being disposed between the bracket and the camera assembly, and the first protrusion bending relative to the support plate toward the camera assembly to abut against the camera assembly.

[0012] The first protrusion bends towards the camera assembly and presses against it, creating a compressive force that effectively restricts the camera assembly's displacement. This ensures the camera assembly is securely fixed to the mounting bracket, thus improving the overall structural stability. The design of the first protrusion also simplifies the installation of the camera assembly, eliminating the need for additional tools or materials.

[0013] In one possible implementation, the first protrusion includes a first segment and a second segment connected together; the first segment is connected to a support plate and extends in a direction away from the circuit board, and the second segment bends relative to the first segment toward the camera assembly and contacts the camera assembly. In the thickness direction of the circuit board, the projection of the second segment at least partially overlaps with the camera assembly.

[0014] Because at least a portion of the second segment's orthographic projection in the circuit board thickness direction (Z direction) overlaps with the orthographic projection of the camera assembly, and the second segment can abut against the camera assembly, it effectively limits the camera assembly in the Z direction. Simultaneously, the first segment, connecting to the support plate and extending outward, can cooperate with the camera assembly from the side to achieve lateral limiting. Through this structure, the camera assembly is limited in multiple directions, further improving its installation stability.

[0015] In one possible implementation, the fastener includes three first protrusions, namely a first sub-protrusion, a second sub-protrusion, and a third sub-protrusion. The support plate has a plate-like structure; wherein the first and second sub-protrusions are distributed on the support plate along a first direction, and the first and third sub-protrusions are distributed on the support plate along a second direction, the first and second directions intersecting.

[0016] Three first protrusions are respectively located at the three corners of the support plate, forming a limiting structure with a single-sided opening. This enables multi-directional limiting of the camera assembly, improving its installation stability; on the other hand, it facilitates the quick insertion of the camera assembly through the fourth corner without the first protrusion, thereby improving assembly efficiency and reducing manufacturing costs.

[0017] In one possible implementation, the fastener further includes a second protrusion connected to the support plate and bent toward the circuit board, the second protrusion being fixedly connected to the bracket.

[0018] By setting a second protrusion on the fastener and bending it towards the circuit board to achieve a fixed connection with the bracket, not only is the connection strength between the fastener and the bracket enhanced, making the connection between the fastener and the bracket more stable, but it also helps to improve the installation stability of the camera assembly fixed on the fastener.

[0019] In one possible implementation, the second protrusion has an L-shaped structure, including a third segment and a fourth segment connected together. The third segment is connected to the support plate and extends in a direction away from the camera assembly, while the fourth segment is mounted on the bracket and fixedly connected to the bracket.

[0020] The fourth section of the second protrusion is fixedly connected to the bracket, which can more firmly fix the fastener to the bracket and effectively prevent the fastener from deforming or loosening during use, thereby significantly improving the structural stability of the camera assembly installation and the reliability of long-term operation.

[0021] In one possible implementation, the fourth segment of the second protrusion has a first snap-fit ​​portion, the bracket has a second snap-fit ​​portion, and the first snap-fit ​​portion and the second snap-fit ​​portion snap-fit ​​each other.

[0022] The precise matching and snap-fit ​​between the first and second snap-fit ​​parts ensures a reliable mechanical connection between the fastener and the bracket. This snap-fit ​​structure not only improves the overall mechanical strength of the electronic device but also enhances its resistance to external vibrations or impacts. Furthermore, compared to traditional screws or other fixing methods, this snap-fit ​​structure eliminates the need for additional tools during assembly, effectively simplifying installation steps, reducing assembly complexity, and thus improving assembly efficiency and ease of operation.

[0023] In one possible implementation, the first snap-fit ​​portion and the second snap-fit ​​portion each include a positioning hole and a positioning post, with at least a portion of the positioning post located within the positioning hole.

[0024] By embedding the positioning pin into the positioning hole, displacement of the fastener during use can be effectively prevented, thereby improving the stability of the connection between the fastener and the bracket. Furthermore, the clear mating relationship between the positioning pin and the positioning hole guides the accurate alignment and installation of the fastener, avoiding misalignment and improving assembly efficiency.

[0025] In one possible implementation, the fastener includes a fourth sub-protrusion and a fifth sub-protrusion. Specifically, in a first direction, the fourth sub-protrusion is distributed between the first and second sub-protrusions; in a second direction, the fifth sub-protrusion is located between the first and third sub-protrusions and is arranged opposite to them.

[0026] By setting two second protrusions on the support plate, which serve as the fourth and fifth sub-protrusions respectively, the fasteners can be positioned and fixed simultaneously in the first and second directions. This significantly improves the structural stability of the fasteners in multiple directions, enhances the overall connection strength, and effectively prevents the fasteners from shifting or loosening due to external forces, further improving the stability of the camera assembly installation.

[0027] In one feasible configuration, the support plate, the first protrusion, and the second protrusion are integrally formed.

[0028] The fasteners, manufactured using a one-piece molding process, enable seamless connection of the overall structure, eliminating the need for additional splicing or assembly of multiple parts. This simplifies the assembly process while ensuring structural strength.

[0029] In one possible implementation, the electronic device also includes a gel portion located between a support plate and a bracket, the support plate being connected to the bracket via the gel portion.

[0030] This not only ensures a secure connection between the fastener and the bracket through the fourth and fifth sub-protrusions, but also allows for the installation of a colloid between the support plate and the bracket, further enhancing the overall connection strength between the fastener and the bracket. The colloid also effectively buffers external vibrations or impact stresses, preventing structural loosening caused by mechanical deformation and improving the stability and reliability of the entire fastening structure.

[0031] In one possible implementation, the electronic device further includes a back cover and a decorative assembly. The back cover has a mounting slot, and the decorative assembly is connected to the back cover at the mounting slot. The decorative assembly has multiple positioning protrusions that abut against the camera assembly.

[0032] After the back cover is installed, the four positioning protrusions abut against the peripheral surfaces of the camera assembly to achieve circumferential positioning of the camera assembly. In this way, in addition to the main fixation of the camera assembly by the fasteners, the decorative components further provide auxiliary positioning, thereby effectively improving the installation accuracy of the camera assembly and the stability of the overall structure.

[0033] Secondly, this application provides a circuit board assembly, including: a circuit board, a bracket, and a fixing member; a connector is disposed on the circuit board;

[0034] The bracket is mounted on the circuit board, with at least a portion of the bracket located on the side of the connector away from the circuit board; the fastener is mounted on the side of the bracket away from the circuit board and is connected to the bracket; the fastener is used to fix the camera assembly.

[0035] The bracket can secure the connector. By utilizing the structural characteristics of this bracket, the camera assembly is mounted on the side of the bracket away from the circuit board via a fastener, effectively securing the camera assembly. Since there is no need for a separate bracket specifically for securing the camera assembly, it does not occupy space on the circuit board used for other electronic components, thereby increasing the effective area of ​​the circuit board available for electronic components and improving the space utilization rate of the circuit board.

[0036] In one possible implementation, at least a portion of the bracket contacts the connector to limit the connector's displacement in the thickness direction of the circuit board.

[0037] By making at least a portion of the bracket contact the side of the connector away from the circuit board, the displacement of the connector in the thickness direction of the circuit board can be further restricted, thereby enhancing the stability of the connector connection and preventing connection loosening or signal interruption caused by external forces.

[0038] In one possible implementation, the fastener includes a connected support plate and a first protrusion, the support plate being disposed between the bracket and the camera assembly, and the first protrusion bending relative to the support plate toward the camera assembly to abut against the camera assembly.

[0039] The first protrusion bends towards the camera assembly and presses against it, creating a compressive force that effectively restricts the camera assembly's displacement. This ensures the camera assembly is securely fixed to the mounting bracket, thus improving the overall structural stability. The design of the first protrusion also simplifies the installation of the camera assembly, eliminating the need for additional tools or materials.

[0040] In one possible implementation, the first protrusion includes a first segment and a second segment connected together; the first segment is connected to a support plate and extends in a direction away from the circuit board, and the second segment bends relative to the first segment toward the camera assembly and contacts the camera assembly. In the thickness direction of the circuit board, the projection of the second segment at least partially overlaps with the camera assembly.

[0041] Because at least a portion of the second segment's orthographic projection in the circuit board thickness direction (Z direction) overlaps with the orthographic projection of the camera assembly, and the second segment can abut against the camera assembly, it effectively limits the camera assembly in the Z direction. Simultaneously, the first segment, connecting to the support plate and extending outward, can cooperate with the camera assembly from the side to achieve lateral limiting. Through this structure, the camera assembly is limited in multiple directions, further improving its installation stability.

[0042] In one possible implementation, the fastener includes three first protrusions, namely a first sub-protrusion, a second sub-protrusion, and a third sub-protrusion. The support plate has a plate-like structure; wherein the first and second sub-protrusions are distributed on the support plate along a first direction, and the first and third sub-protrusions are distributed on the support plate along a second direction, the first and second directions intersecting.

[0043] Three first protrusions are respectively located at the three corners of the support plate, forming a limiting structure with a single-sided opening. This enables multi-directional limiting of the camera assembly, improving its installation stability; on the other hand, it facilitates the quick insertion of the camera assembly through the fourth corner without the first protrusion, thereby improving assembly efficiency and reducing manufacturing costs.

[0044] In one possible implementation, the fastener further includes a second protrusion connected to the support plate and bent toward the circuit board, the second protrusion being fixedly connected to the bracket.

[0045] By setting a second protrusion on the fastener and bending it towards the circuit board to achieve a fixed connection with the bracket, not only is the connection strength between the fastener and the bracket enhanced, making the connection between the fastener and the bracket more stable, but it also helps to improve the installation stability of the camera assembly fixed on the fastener.

[0046] In one possible implementation, the second protrusion has an L-shaped structure, including a third segment and a fourth segment connected together. The third segment is connected to the support plate and extends in a direction away from the camera assembly, while the fourth segment is mounted on the bracket and fixedly connected to the bracket.

[0047] The fourth section of the second protrusion is fixedly connected to the bracket, which can more firmly fix the fastener to the bracket and effectively prevent the fastener from deforming or loosening during use, thereby significantly improving the structural stability of the camera assembly installation and the reliability of long-term operation.

[0048] In one possible implementation, the fourth segment of the second protrusion has a first snap-fit ​​portion, the bracket has a second snap-fit ​​portion, and the first snap-fit ​​portion and the second snap-fit ​​portion snap-fit ​​each other.

[0049] The precise matching and snap-fit ​​between the first and second snap-fit ​​parts ensures a reliable mechanical connection between the fastener and the bracket. This snap-fit ​​structure not only improves the overall mechanical strength of the electronic device but also enhances its resistance to external vibrations or impacts. Furthermore, compared to traditional screws or other fixing methods, this snap-fit ​​structure eliminates the need for additional tools during assembly, effectively simplifying installation steps, reducing assembly complexity, and thus improving assembly efficiency and ease of operation.

[0050] In one possible implementation, the first snap-fit ​​portion and the second snap-fit ​​portion are respectively a positioning hole and a positioning post, with at least a portion of the positioning post located inside the positioning hole.

[0051] By embedding the positioning pin into the positioning hole, displacement of the fastener during use can be effectively prevented, thereby improving the stability of the connection between the fastener and the bracket. Furthermore, the clear mating relationship between the positioning pin and the positioning hole guides the accurate alignment and installation of the fastener, avoiding misalignment and improving assembly efficiency.

[0052] In one possible implementation, the fastener includes a fourth sub-protrusion and a fifth sub-protrusion. Specifically, in a first direction, the fourth sub-protrusion is distributed between the first and second sub-protrusions; in a second direction, the fifth sub-protrusion is located between the first and third sub-protrusions and is arranged opposite to them.

[0053] By setting two second protrusions on the support plate, which serve as the fourth and fifth sub-protrusions respectively, the fasteners can be positioned and fixed simultaneously in the first and second directions. This significantly improves the structural stability of the fasteners in multiple directions, enhances the overall connection strength, and effectively prevents the fasteners from shifting or loosening due to external forces, further improving the stability of the camera assembly installation.

[0054] In one feasible configuration, the support plate, the first protrusion, and the second protrusion are integrally formed.

[0055] The fasteners, manufactured using a one-piece molding process, enable seamless connection of the overall structure, eliminating the need for additional splicing or assembly of multiple parts. This simplifies the assembly process while ensuring structural strength. Attached Figure Description

[0077] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0078] This application provides an electronic device, such as a mobile phone, tablet, laptop, smart home device, smart wearable device (e.g., smartwatch, smart bracelet, smart glasses, smart helmet), virtual reality (VR) electronic device, augmented reality (AR) electronic device, etc. The electronic device can also be a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, an electronic device in a 5G network, or an electronic device in a future evolved public land mobile network (PLMN), etc. This application does not specifically limit the type of electronic device.

Figure 2 yes Figure 1 A cross-sectional view at point A-A' Figure 3 yes Figure 2 A magnified view of a section at point D.

[0080] Electronic devices may include a camera assembly 400, which can be used to capture images and convert light signals caused by light into corresponding electrical signals. The camera assembly 400 is widely used in various electronic devices with image acquisition capabilities, such as smartphones, tablets, smart wearable devices, and security monitoring systems.

[0081] In some examples, camera assembly 400 may include a variable aperture, a lens assembly, and a motor. In other examples, camera assembly 400 may also include other structural components.

[0082] This application provides a circuit board assembly that can be used in the aforementioned electronic device, which can reliably fix the camera assembly 400. For example... Figure 3 As shown, the circuit board assembly may include a circuit board 100, on which a connector 101 is provided. For example, the connector 101 may be a board-to-board connector (B2B connector) for achieving electrical connection and signal transmission with another circuit board. The board-to-board connector typically consists of a male connector and a female connector, which complete the secure connection between the two circuit boards through a plug-in mating process.

[0083] To ensure the reliability of the electrical connection of connector 101, a bracket 200 can be provided on the circuit board 100. At least a portion of the bracket 200 can be located on the side of connector 101 away from the circuit board 100. By limiting and fixing connector 101, it can prevent connector 101 from loosening due to external forces (such as vibration or impact), thereby improving the structural stability of connector 101 connection and ensuring the reliability of signal transmission.

[0084] Figure 4 This is a schematic diagram of the structure of another electronic device provided in an embodiment of this application. For example... Figure 3 and Figure 4 As shown, the circuit board assembly may further include a fixing member 300, which may be disposed on the side of the bracket 200 opposite to the circuit board 100, and the fixing member 300 may be connected to the bracket 200. The camera assembly 400 may be located on the side of the fixing member 300 opposite to the circuit board 100, and the camera assembly 400 is mounted on the fixing member 300.

[0085] In this embodiment, the bracket 200 can fix the connector 101. By utilizing the structural characteristics of the bracket 200, the camera assembly 400 is positioned on the side of the bracket 200 away from the circuit board 100 via the fixing member 300, thus achieving effective fixation of the camera assembly 400. Since there is no need to set up an additional independent bracket specifically for fixing the camera assembly 400, it does not occupy the space on the circuit board 100 used for arranging other electronic devices, thereby increasing the effective area of ​​the circuit board 100 that can be used to arrange electronic devices, and thus improving the space utilization rate of the circuit board 100.

[0086] In some examples, at least a portion of the bracket 200 contacts the side of the connector 101 away from the circuit board 100 to limit the displacement of the connector 101 in the thickness direction of the circuit board 100.

[0087] By bringing at least a portion of the bracket 200 into contact with the side of the connector 101 away from the circuit board 100, the displacement of the connector 101 in the thickness direction of the circuit board 100 can be further restricted, thereby enhancing the stability of the connector 101 connection and preventing connection loosening or signal interruption caused by external forces.

[0088] Figure 5 This is a structural schematic diagram of a fastener provided in an embodiment of this application. Figure 6 This is an assembly diagram of a fastener and camera assembly provided in an embodiment of this application. Figure 5 and Figure 6 As shown, the fastener 300 may include a support plate 301 and a first protrusion 302 connected to each other. The support plate 301 is disposed between the bracket 200 and the camera assembly 400. The first protrusion 302 bends relative to the support plate 301 toward the camera assembly 400 and abuts against the camera assembly 400.

[0089] The first protrusion 302 bends towards the camera assembly 400 and abuts against it, creating a compressive force between the first protrusion 302 and the camera assembly 400. This effectively restricts the displacement of the camera assembly 400, ensuring that it is securely fixed to the fixing member 300, thereby improving the overall structural stability. The design of the first protrusion 302 also simplifies the installation of the camera assembly 400, eliminating the need for additional fixing tools or materials.

[0090] For example, such as Figure 6 As shown, the first protrusion 302 in the fastener 300 may include a first segment 3021 and a second segment 3022 connected to each other. The first segment 3021 may be connected to the support plate 301 and extends in a direction away from the circuit board 100. The second segment 3022 bends relative to the first segment 3021 toward the camera assembly 400 and contacts the camera assembly 400. For example, the second segment 3022 may abut against the camera assembly 400.

[0091] In the thickness direction of the circuit board 100, the projection of the second segment 3022 at least partially overlaps with the camera assembly 400.

[0092] Since at least a portion of the second segment 3022 overlaps with the orthographic projection of the camera assembly 400 in the thickness direction (Z direction) of the circuit board 100, and the second segment 3022 can abut against the camera assembly 400, it effectively limits the camera assembly 400 in the Z direction. Simultaneously, the first segment 3021 connects to the support plate 301 and extends outward, enabling it to cooperate with the camera assembly 400 from the side for lateral limiting. Through this structure, the camera assembly 400 is limited in multiple directions, further improving its installation stability.

[0093] Figure 7 This is a schematic diagram of another fastener provided in an embodiment of this application. (See attached diagram.) Figure 7 As shown, the fastener 300 may include three first protrusions 302, namely a first sub-protrusion 302a, a second sub-protrusion 302b and a third sub-protrusion 302c.

[0094] The support plate 301 in the fastener 300 has a plate-like structure. First sub-protrusions 302a and 302b are distributed on the support plate 301 along a first direction, and first sub-protrusions 302a and 302c are distributed on the support plate 301 along a second direction. The first and second directions intersect. For example, the first direction can be the X-direction in a Cartesian coordinate system, and the second direction can be the Y-direction in a Cartesian coordinate system, and the two are perpendicular to each other in the Cartesian coordinate system.

[0095] It should be noted that the "first direction is perpendicular to the second direction" in this application is not limited to a strict 90° angle. In practical applications, there may be certain manufacturing or assembly errors. For example, any angle between 88° and 92° is considered to be approximately perpendicular.

[0096] In some examples, the support plate 301 can be a rectangular plate structure. The support plate 301 has a first side L1 and a second side L2 arranged opposite to each other, and a third side L3 and a fourth side L4 arranged opposite to each other, with the first side L1, the third side L3, the second side L2 and the fourth side L4 connected end to end in sequence. Among them, the first sub-protrusion 302a and the second sub-protrusion 302b are located at both ends of the first side L1, and the third sub-protrusion 302c is located at one end of the second side L2 and is arranged opposite to the first sub-protrusion 302a.

[0097] In this embodiment, three first protrusions 302 are respectively disposed at the three corners of the support plate 301, forming a limiting structure with a single-sided opening. This enables multi-directional limiting of the camera assembly 400, improving its installation stability; on the other hand, it facilitates the quick insertion of the camera assembly 400 through the fourth corner without a fixing part, thereby improving assembly efficiency and reducing manufacturing costs.

[0098] In the embodiments of this application, such as Figure 5 As shown, the fastener 300 may further include a second protrusion 303, which can be connected to the support plate 301 and bent relative to the support plate 301 toward the circuit board 100. The second protrusion 303 can be fixedly connected to the bracket 200.

[0099] By providing a second protrusion 303 on the fixing member 300 and bending it toward the circuit board 100 to achieve a fixed connection with the bracket 200, not only is the connection strength between the fixing member 300 and the bracket 200 enhanced, making the connection between the fixing member 300 and the bracket 200 more stable, but it also helps to improve the installation stability of the camera assembly 400 fixed on the fixing member 300.

[0100] For example, such as Figure 5 As shown, the second protrusion 303 in the fastener 300 can be L-shaped, and the second protrusion 303 can include a third segment 3031 and a fourth segment 3032 connected to each other. For example, the third segment 3031 and the fourth segment 3032 can be perpendicular to each other.

[0101] The third segment 3031 of the second protrusion 303 can be connected to the support plate 301 and extend in the direction away from the camera assembly 400. The fourth segment 3032 of the second protrusion 303 can be set on the bracket 200 and fixedly connected to the bracket 200.

[0102] The fourth segment 3032 in the second protrusion 303 is fixedly connected to the bracket 200, which can more firmly fix the fastener 300 to the bracket 200, effectively preventing the fastener 300 from deforming or loosening during use, thereby significantly improving the structural stability of the camera assembly 400 installation and the reliability of long-term operation.

[0103] Figure 8 This is an assembly diagram of a bracket and fastener provided in an embodiment of this application. (In conjunction with...) Figure 5 and Figure 8 As shown, the fourth segment 3032 in the second protrusion 303 may have a first snap-fit ​​portion 30321, and the bracket 200 may have a second snap-fit ​​portion 201. The first snap-fit ​​portion 30321 and the second snap-fit ​​portion 201 snap-fit ​​each other.

[0104] Through the precise matching and snap-fitting of the first snap-fit ​​part 30321 and the second snap-fit ​​part 201, a reliable mechanical connection is achieved between the fastener 300 and the bracket 200. This snap-fit ​​structure not only improves the overall mechanical strength of the electronic device but also enhances its resistance to external vibrations or impacts. Furthermore, compared to traditional screws or other fixing methods, this snap-fit ​​structure allows for assembly without additional tools, effectively simplifying installation steps, reducing assembly complexity, and thus improving assembly efficiency and ease of operation.

[0105] In some examples, such as Figure 5 and Figure 8 As shown, the first snap-fit ​​portion 30321 and the second snap-fit ​​portion 201 can be a positioning hole P and a positioning post Q, respectively, with at least a portion of the positioning post Q located inside the positioning hole P.

[0106] By embedding the positioning pin Q into the positioning hole P, displacement of the fastener 300 during use can be effectively prevented, thereby improving the stability of the connection between the fastener 300 and the bracket 200. Simultaneously, because the positioning pin Q and the positioning hole P have a clear mating relationship, the fastener 300 can be guided to accurate alignment during installation, avoiding misalignment and improving assembly efficiency.

[0107] In this application example, the first latching portion 30321 and the second latching portion 201 can be flexibly designed as complementary forms that match each other. That is, the first latching portion 30321 and the second latching portion 201 can be interchanged as positioning holes P or positioning posts Q. If the first latching portion 30321 is designed as a positioning hole P, then the second latching portion 201 matches as a positioning post Q; conversely, if the first latching portion 30321 is designed as a positioning post Q, then the second latching portion 201 is adapted to be a positioning hole P. For clarity, this application uses the example of the first latching portion 30321 as a positioning hole P and the second latching portion 201 as a positioning post Q for explanation.

[0108] In the embodiments of this application, such as Figure 7 As shown, the fastener 300 may include two second protrusions 303, namely a fourth sub-protrusion 303a and a fifth sub-protrusion 303b.

[0109] In the first direction, the fourth sub-protrusion 303a is distributed between the first sub-protrusion 302a and the second sub-protrusion 302b; in the second direction, the fifth sub-protrusion 303b is located between the first sub-protrusion 302a and the third sub-protrusion 302c, and is arranged opposite to them.

[0110] In some examples, such as Figure 7 As shown, the fourth sub-protrusion 303a is connected to the support plate 301 at the first side L1 and is distributed between the first sub-protrusion 302a and the second sub-protrusion 302b. The fifth sub-protrusion 303b is connected to the support plate 301 at the third side L3.

[0111] By providing two second protrusions 303 on the support plate 301, which serve as the fourth sub-protrusion 303a and the fifth sub-protrusion 303b respectively, the fastener 300 can be positioned and fixed simultaneously in the first and second directions, thereby significantly improving the structural stability of the fastener 300 in multiple directions, enhancing the overall connection strength, and effectively preventing the fastener 300 from shifting or loosening due to external forces, further improving the stability of the camera assembly 400 installation.

[0112] In the embodiments of this application, such as Figure 5As shown, the support plate 301, the first protrusion 302, and the second protrusion 303 in the fastener 300 can be integrally formed. For example, they can be manufactured using processes such as stamping, casting, computer numerical control machining, or 3D printing.

[0113] The fastener 300, manufactured using a one-piece molding process, enables seamless connection of the overall structure without the need for additional splicing or assembly of multiple parts. This simplifies the assembly process while ensuring structural strength.

[0114] Figure 9 This is a structural schematic diagram of another fastener provided in an embodiment of this application. Figure 10 This is a partial schematic diagram of an electronic device provided in an embodiment of this application. For example... Figure 9 and Figure 10 As shown, the circuit board assembly may also include an adhesive portion 500 located between the support plate 301 and the bracket 200, and the support plate 301 can be connected to the bracket 200 through the adhesive portion 500.

[0115] For example, the colloid portion 500 may be an adhesive material used to secure the connection between the support plate 301 and the bracket 200, such as adhesive backing, epoxy resin, UV-curable adhesive or other adhesives suitable for industrial applications.

[0116] This not only ensures a secure connection between the fastener 300 and the bracket 200 through the fourth sub-protrusion 303a and the fifth sub-protrusion 303b, but also further enhances the overall connection strength between the fastener 300 and the bracket 200 by providing an adhesive portion 500 between the support plate 301 and the bracket 200. The adhesive portion 500 also effectively buffers external vibrations or impact stresses, preventing structural loosening caused by mechanical deformation and improving the stability and reliability of the entire fixing structure.

Figure 12 yes Figure 11 A cross-sectional view at B-B' Figure 13 yes Figure 12 A magnified view of a section at point E. (See attached image.) Figure 13 As shown, the electronic device may also include a back cover 600 and a decorative component 700.

[0118] Figure 14 This is a schematic diagram of the structure of a back cover provided in an embodiment of this application. Figure 15 This is a schematic diagram of the structure of a back cover provided in an embodiment of this application from another perspective. For example... Figure 14 and Figure 15 As shown, the back cover 600 may have a mounting slot, and the decorative component 700 is connected to the back cover 600 at the mounting slot.

[0119] The decorative component 700 has multiple positioning protrusions 701 that can abut against the camera component 400. For example, there are four positioning protrusions 701.

[0120] After the back cover 600 is installed, multiple positioning protrusions 701 abut against the peripheral surface of the camera assembly 400 to achieve circumferential positioning of the camera assembly 400. In this way, based on the main fixation of the camera assembly 400 by the fastener 300, the decorative component 700 provides an auxiliary positioning function, thereby effectively improving the installation accuracy of the camera assembly 400 and the stability of the overall structure.

[0121] In some examples, the thickness of the fastener 300 ranges from 0.1 mm to 0.3 mm. For example, the thickness of the fastener 300 can be 0.2 mm. By controlling the thickness of the fastener 300 within this range, not only can the structural strength and overall reliability of the machine be guaranteed, but manufacturing costs can also be effectively controlled.

[0122] The circuit board assembly provided in this application can be used not only in the aforementioned electronic devices, but also in automotive or medical devices.

[0123] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
