Abstract
Description
Technical Field
[0001] This application relates to the field of communication-related technology, specifically to an electronic device. Background Technology
[0002] As existing mobile phones, tablets, and other devices become increasingly feature-rich, the demands on the design and utilization of internal space and components also rise. For example, the area occupied by the circuit board in a mobile phone, and the impact of components like cameras and microphones on the phone's thickness, all contribute to this challenge. Therefore, improving the utilization of internal space in electronic devices is an urgent problem to be solved. Utility Model Content
[0003] Embodiments of this application provide an electronic device that makes full use of its internal structure and improves the utilization rate of internal space.
[0004] Please provide an electronic device, the electronic device including a circuit board, a connector, a camera bracket, and a clamping bracket. The circuit board includes a front side, the connector and the camera bracket are connected to the front side, and the connector and the camera bracket are disposed adjacent to each other. The camera bracket includes a bracket body and an extension, the extension extending away from the bracket body from one side and extending towards the connector. The clamping bracket includes a main body and a first connecting end, the first connecting end being located on one side of the main body in the length direction. In the thickness direction of the electronic device, the first connecting end of the clamping bracket is stacked on the front side of the circuit board, and the first connecting end is fixed to the circuit board by screws. The main body abuts against the side of the connector facing away from the circuit board, and in the thickness direction of the electronic device, the extension is stacked and abuts against the portion of the clamping bracket facing away from the first connecting end.
[0005] In existing technologies, the connector's clamping bracket is screwed to the circuit board on both sides, or screwed on one side and clamped to the other side with an auxiliary bracket. This method occupies circuit board area and requires space for the auxiliary bracket, which is not conducive to the utilization of electronic device space. In this embodiment, the existing camera bracket is used, with an extension provided on the camera bracket to press against one end of the clamping bracket in the thickness direction, while the other end of the clamping bracket is screwed to the circuit board. This not only limits the connector's position but also eliminates the need for two screw holes on the circuit board and the need to reserve space for the auxiliary bracket, saving circuit board area and improving utilization. Moreover, using the camera bracket adjacent to the connector improves space compactness and saves materials and assembly steps.
[0006] In one embodiment, the extension overlaps with and abuts against the end of the main body facing away from the connector. This reduces the length dimension of the clamping bracket, as the extension is located on the clamping bracket and overlaps with the main body, eliminating the need for additional space on the circuit board and significantly saving circuit board area; thus improving the utilization rate of internal space in electronic devices.
[0007] In one embodiment, the clamping bracket further includes a second connecting end, which is located at both ends of the first connecting end in a first direction, and the extension is stacked and presses against the second connecting end, wherein the first direction is perpendicular to the thickness direction of the electronic device.
[0008] In one embodiment, the main body includes a first surface and a second surface facing away from each other. The first connecting end is formed by bending one end of the main body away from the first surface and then away from the main body. The second connecting end is formed by bending the other end of the main body away from the first surface and then away from the main body. In the thickness direction of the electronic device, the second connecting end is spaced apart from the circuit board. The second connecting end is spaced apart from the circuit board and close to the extension in the thickness direction, which facilitates the placement of the extension in the bracket body.
[0009] In one embodiment, the surface of the extension facing the second connecting end is provided with a retaining groove. In the first direction, the second connecting end extends into the retaining groove and is retained by the retaining groove in the thickness direction of the electronic device. In this embodiment, the height of the extension protruding from the circuit board is greater than the height of the connector protruding from the circuit board. The extension is located above the main body of the clamping bracket and presses against the main body, thereby pressing the connector. This reduces the length dimension of the clamping bracket. The extension is located on the clamping bracket and overlaps with the main body, eliminating the need to occupy additional space on the circuit board and greatly saving the area of the circuit board; thus improving the utilization rate of the internal space of the electronic device.
[0010] In one embodiment, in the first direction, the end of the main body away from the first connecting end protrudes from the connector, and in the thickness direction of the electronic device, the orthographic projection of the portion of the main body protruding from the connector lies entirely on the extension. In this embodiment, having the end of the main body away from the first connecting end protrude from the connector increases the contact area between the camera bracket and the clamping bracket.
[0011] In one embodiment, a first buffer is provided between the body and the connector. The first buffer may be a cushioning foam, which is clamped between the surfaces of the body and the connector, and can buffer the impact force generated by the clamping bracket on the connector, and also avoid friction between the clamping bracket and the connector.
[0012] In one embodiment, a second buffer is provided between the extension and the portion of the clamping bracket that overlaps. The second buffer is used to buffer the stress between the camera bracket and the clamping bracket.
[0013] In one embodiment, the electronic device further includes a rear shell and a camera assembly. The camera assembly is connected to the circuit board via a camera bracket. The rear shell includes a camera decorative element, which is recessed from the inner side to the outer side of the rear shell to form a recess. The camera assembly protrudes from the rear shell, and the camera decorative element surrounds the camera assembly. The camera bracket is located in the recess. In this embodiment, the recess is used to accommodate part of the camera assembly structure and cover the camera bracket. The recess can also accommodate part of the clamping bracket, reducing the space occupied by the clamping bracket in the thickness direction of the electronic device and further improving the utilization of the internal space of the electronic device.
[0014] In one embodiment, the electronic device includes a screen, and the connector includes a female connector disposed on a circuit board and a male connector connected to a flexible circuit board. The flexible circuit board is electrically connected to the screen, the male connector is inserted into the female connector, and a clamping bracket presses the male connector and the female connector together. The connector in this embodiment is used to connect the circuit board and the screen, enabling electrical communication between them. The connector can also be a camera module connector, a speaker connector, or a connector for other devices. Attached Figure Description

For ease of explanation, this application uses a mobile phone as an example of an electronic device for illustration.
[0029] For ease of description below, let's establish... Figure 1The XYZ coordinate system is shown. The width direction of the electronic device 1000 is defined as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. The X, Y, and Z axes are mutually perpendicular. It is understood that the coordinate system of the electronic device 1000 can be flexibly set according to actual needs. This application only provides... Figure 1 The example shown is not intended to constitute a particular limitation on this application.
[0030] Electronic device 1000 includes a mid-frame 200, a screen 300, a housing 400, a circuit board 100, a battery (not shown), and a processor (not shown), as well as electronic components such as a camera assembly 50, a speaker module, and connectors 60. The housing 400 and screen 300 are located on opposite sides of the mid-frame 200 in the thickness direction. The circuit board 100, camera assembly 50, multiple connectors 60, and battery (not shown) are all mounted on the mid-frame 200 and covered by the housing. The camera assembly 50, speaker module, connectors 60, and processor can be mounted on the circuit board. The multiple connectors 60 are used to connect the electronic components and the circuit board of the electronic device. The multiple connectors 60 can be screen connectors, camera connectors, power connectors, etc., for electrical connection and data transmission. The processor can be the CPU (central processing unit) of the electronic device 1000. The battery provides power to the components that enable the electronic device to perform its functions.
[0031] In this embodiment, the mid-frame 200 includes a battery slot and a mounting slot, which are arranged adjacent to each other. The battery is housed in the battery slot. Electronic components such as the circuit board 100, camera assembly 50, and speaker module are located in the mounting slot. The circuit board is fixedly connected to the mid-frame 200, and can be fixed by a circuit board bracket or the like. The circuit board 100 has holes cut out to avoid the camera assembly 50. Of course, if necessary, the camera assembly 50 can also be mounted on the circuit board 100. The camera assembly 50 includes a main camera and an auxiliary camera. The screen 300 is located on the side of the mid-frame 200 facing away from the mounting slot and is electrically connected to the circuit board via a connector.
[0032] Please see Figure 3 , Figure 3 for Figure 1The diagram shows a simplified internal structure of an embodiment of the electronic device. A connector 60, a first bracket 66, and a second bracket 67 are provided on the surface of a circuit board 100. The connector 60 is fixed and connected to the surface of the circuit board 100 and is electrically connected to the circuit board. The first bracket 66 includes a first end 661 and a second end 662. The first end 661 and the second end 662 are located on opposite sides of the length direction of the first bracket 66. In the height direction (Z-axis) of the first bracket 66, the distance from the first end 661 to the circuit board 100 is less than the distance from the second end 662 to the circuit board. In this embodiment, the first bracket 66 is a cover structure. The second bracket 67 can be a metal structure or a plastic structure. The second bracket 67 includes a fixed end 671 and a retaining end 672, which are arranged in the thickness direction of the second bracket 67. The fixed end 671 of the second bracket 67 is fixed to the surface of the circuit board 100 by welding or screws. In the Z-axis direction, the retaining end 672 is spaced apart from the circuit board and the fixed end 671.
[0033] In the X-axis or Y-axis direction, the second bracket 67 is located at one end of the first bracket 66 and is spaced apart from the second end 662; the height of the second bracket 67 is less than the height of the first bracket 66. The first bracket 66 covers the end face of the connector 60 facing away from the circuit board 100. Screws pass through the first end 661 and the circuit board 100 to fix the first end 661 to the circuit board. The second end 662 is located between the fixed end 671 and the retaining end 672. In the thickness direction, the second end 662 and the retaining end 672 retain each other. The second bracket 67 and the screw cooperate to fix the first bracket 66 to the circuit board 100 and press against the connector 60 to prevent the connector 60 from detaching from the circuit board 100.
[0034] Please see Figure 4 and Figure 5 , Figure 4 for Figure 1 A partial structural schematic diagram of one embodiment of the electronic device shown; Figure 5 for Figure 4 An exploded view of a portion of the structure of the electronic device is shown. Figure 4 Only a portion of the internal structure of the electronic device 1000 is shown. The circuit board 100 includes a front side 1001 and a back side (not shown). The camera assembly 50, connector 60, and camera bracket 55 are located on the front side 1001. The connector 60 is located on the circuit board 100 and around the camera assembly 50. Furthermore, the connector 60 on the circuit board 100 has a clamping bracket to ensure stable insertion between the connector 60 and the circuit board 100.
[0035] In this embodiment, connector 60 is used as an example to connect the screen and the circuit board. Connector 60 includes a male connector 61 and a female connector 62. The male connector 61 is connected to a flexible circuit board 63, and the female connector 62 is fixed and connected to the front side 1001 of the circuit board 100, and is electrically connected to the circuit board. The other end of the flexible circuit board 63 is connected to the screen 300. The flexible circuit board 63 passes through the middle frame 200 and is connected and electrically connected to the connector or bonding area of the screen 300. The flexible circuit board 63 is flexible and can utilize the space between components inside the middle frame 200. The male connector 61 and the female connector 62 are inserted to electrically connect the flexible circuit board 63 to the circuit board 100.
[0036] The electronic device further includes a clamping bracket 70 and a camera bracket 80. The camera bracket 80 may include one or more brackets for matching multiple cameras within the camera assembly 50, thereby supporting and fixing the camera assembly 50 to the circuit board 100 and the mid-frame 200. The camera bracket 80 may be a single independent structure or several independent structures. In this embodiment, only one camera bracket 80 located on the front 1001 is described as an example. Other parts of the camera bracket 80 are not shown in this embodiment and are not limited thereto. The camera bracket 80 is fixed to the circuit board 100 located on the front 1001. In this embodiment, the camera bracket 80 includes a bracket body 81, a limiting groove 82, and a clearance groove 83. The limiting groove 82 is formed on the surface of the bracket body 81 in the thickness direction for the camera assembly 50 to pass through, thereby limiting the camera assembly 50. The bracket body 81 also has a protruding support foot 86 in the thickness direction, which is used for fixed connection with the circuit board 100 and the mid-frame. Typically, the support foot 86 is fixedly connected to the circuit board 100 and the mid-frame by screws. The clearance groove 83 is provided on the support foot 86 or other parts of the bracket body 81 to avoid functional devices such as resistors and connectors located on the front side 1001 of the circuit board 100. The camera bracket 80 also includes an extension 87, which is formed by extending from one side of the bracket body 81 away from the bracket body 81.
[0037] The clamping bracket 70 includes a main body 71, a first connecting end 72, and a second connecting end 73. In this embodiment, the main body 71 is a strip-shaped plate, including a first surface 711 and a second surface 712, which are two surfaces along the thickness direction of the clamping bracket 70. The first connecting end 72 and the second connecting end 73 are located at opposite ends along the length direction (first direction) of the main body 71. The first connecting end 72 is formed by bending away from the first surface 711 and away from the main body 71 from the other end of the main body 71. The first connecting end 72 and the second connecting end 73 extend in opposite directions. A through hole 721 is provided on the first connecting end 72 for a screw to pass through. The clamping bracket 70 can be formed by stamping metal.
[0038] Connector 60 is located on one side of camera bracket 80. Clamping bracket 70 covers connector 60. In the thickness (Z-axis) direction, body 71 is located on the side of connector 60 facing away from circuit board 100. First surface 711 faces and contacts connector 60. First connecting end 72 is screwed into screw hole 1003 of circuit board 100 by screw 74, and abuts against front surface 1001. Second connecting end 73 faces camera bracket 80 and is engaged with extension 87 to prevent detachment from circuit board. First connecting end 72 and second connecting end 73 cause body 71 to press against connector 60, thus clamping male head 61 and female head 62. Specifically, in the Z-axis direction, the surface of second connecting end 73 facing away from circuit board 100 and the surface of extension 87 facing circuit board 100 are engaged in the Z-axis direction. The fixing of first connecting end 72 and second connecting end 73 further limits and fixes body 71 to press against connector 60. In the thickness direction, the second connecting end 73 is lower than the first surface 711 of the main body 71 compared to the front surface 1001. It can be understood that the second connecting end 73 partially overlaps with the extension 87 in the Z-axis direction. The length of the second connecting end 73 is less than the length of the first connecting end 72.
[0039] In this embodiment, the clamping bracket 70 is fixed to the circuit board 100 by screws and the camera bracket 80, clamping the male connector 61 and female connector 62 and ensuring they are properly connected. This limits the connector 60 in the thickness direction of the electronic device 1000, preventing it from loosening or failing during use and ensuring the stability of the connection between the connector 60 and the circuit board 100. Simultaneously, one end of the clamping bracket 70 is fixed to the circuit board 100 by the camera bracket 80, meaning the second connection end 73 is fixed using the camera bracket 80, rather than... Figure 3In the embodiment shown, both the first connecting end 72 and the second connecting end 73 are fixed with screws, avoiding the need to drill holes on the circuit board for the screws to pass through. This saves the area of the circuit board in the width or length direction of the circuit board 100, thereby improving the utilization rate of the circuit board area. In addition, it also makes full use of the original camera bracket 80 in the electronic device, making reasonable use of the space of the electronic device.
[0040] In this embodiment, the bracket body 81 is located on one side of the connector 60. The height of the extension protruding from the front surface 1001 of the circuit board 100 is greater than the height of the second connecting end 73 of the clamping bracket protruding from the front surface 1001 of the circuit board 100. The extension and the second connecting end 73 are stacked to reduce the area occupied by the circuit board 100.
[0041] like Figure 6 As shown, Figure 6 for Figure 4 The schematic diagram of the electronic device structure shown illustrates one embodiment where the bracket body 81 is located on one side of the connector 60. The second connecting end 73 of the clamping bracket 70 can be omitted. The height of the extension protruding from the front surface 1001 of the circuit board 100 is greater than the height of the connector 60 protruding from the front surface 1001 of the circuit board 100. The extension 87 is located above the first surface 711 of the body 71 of the clamping bracket 70 and presses against the end of the body 71 away from the first connecting end 72, thereby clamping the connector 60. This reduces the length dimension of the clamping bracket 70. The extension is located on the clamping bracket 70 and overlaps and abuts against the body 71, eliminating the need for additional space on the circuit board and greatly saving the area of the circuit board. This improves the utilization rate of the internal space of the electronic device.
[0042] In this embodiment, in the length direction of the clamping bracket 70, the end of the main body 71 away from the first connecting end 72 protrudes from the connector 60, that is, it extends out of the connector, which can be understood as having an extension section. In the thickness direction of the electronic device 1000, the orthographic projection of the part of the main body 71 protruding from the connector 60 (the extension section) is completely located on the extension 87, that is, the protruding part of the main body 71 is completely covered by the extension 87, which can increase the contact area between the camera bracket 80 and the clamping bracket 70, and facilitate the disassembly of the connector 60.
[0043] In one embodiment, the extension 87 has a retaining groove 871 on its surface facing the connector 60. The second connecting end 73 extends into the retaining groove 871 and is retained by the retaining groove 871 to prevent the second connecting end 73 from shifting position, thereby further ensuring the stability of the connection between the second connecting end 73 and the extension 87.
[0044] like Figure 6As shown, in one embodiment, a first buffer 68 is provided between the main body 71 and the connector 60. The first buffer 68 may be a buffer foam, which is sandwiched between the first surface 711 of the main body 71 and the surface of the connector 60, and can buffer the impact force generated by the clamping bracket 70 on the connector 60, and can also avoid friction between the clamping bracket 70 and the connector 60.
[0045] In one embodiment, a second buffer 69 may also be provided between the second connecting end 73 and the extension 87. The second buffer 69 is used to buffer the stress between the camera bracket 80 and the second connecting end 73.
[0046] like Figure 2 As shown, in this embodiment, the rear shell 400 is further provided with a camera decorative element 90, which protrudes from the rear shell 400 and surrounds the camera assembly. The camera decorative element is recessed from the inner side to the outer side of the rear shell to form a recess. The portion of the camera decorative element 90 facing the mid-frame has a recess. In the thickness direction of the electronic device, the recess is used to accommodate part of the structure of the camera assembly 50 and to cover the camera bracket 80. The recess can also accommodate part of the clamping bracket 70, reducing the space occupied by the clamping bracket 70 in the thickness direction of the electronic device and further improving the utilization of the internal space of the electronic device.
[0047] The above are exemplary embodiments of this application. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
