Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art
[0002] Some structural parts in electronic devices such as mobile phones and tablets are positioned with circuit boards and middle frames. For example, the structural parts can be camera modules, speaker modules, etc. The structural parts are assembled inside the electronic device and need to be limited. The circuit board usually needs to be opened with holes to match the limit of the structural parts. In addition, the circuit board itself and the middle frame also need holes to fix the circuit board and the middle frame. In this way, there are more holes on the circuit board, which will reduce the area on the circuit board where other electronic devices can be laid out, and then reduce the effective use area of the circuit board. Utility Model Content
[0003] An embodiment of the present application provides an electronic device for reducing openings in a circuit board to increase the effective use area of the circuit board.
[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:
[0005] The embodiment of the present application provides an electronic device, which includes a first wall panel, a circuit board, a first structural member and a connecting member. The circuit board is stacked with the first wall panel, the circuit board has a first through hole, and the arrangement direction of the first wall panel and the circuit board is a first direction. The first structural member is arranged on the side of the circuit board away from the first wall panel, one of the first structural member and the first wall panel has a limiting column, and the other has a second through hole, the limiting column has a third through hole, and the first through hole, the second through hole, and the third through hole are opposite in the first direction. The connecting member is connected to the third through hole, and the connecting member and the limiting column are integrally penetrated through the first through hole and the second through hole to connect the first wall panel, the circuit board and the first structural member.
[0006] In this way, the limiting column can play two roles. First, the first structural member is limited by the limiting column. The limitation here includes the limitation of the first structural member in its own width direction, length direction and thickness direction by the limiting column, and then the first structural member is fixed to the first wall panel through the limiting column; second, the limiting column passes through the first through hole to limit the circuit board. The limitation here includes the limitation of the circuit board in its own length direction and width direction by the limiting column, and after the first structural member and the first wall panel are connected by the connecting member, the circuit board located between the first structural member and the first wall panel is limited in its own thickness direction by means of the first structural member and the first wall panel.
[0007] In summary, both the first structural member and the circuit board can be fixed to the first wall plate by means of the limiting column, and the first structural member and the circuit board are fixed to the first wall plate by sharing the first through hole. Therefore, the number of holes on the circuit board used to fix itself and the number of holes used to fix the first structural member are reduced, and the area on the circuit board used to connect other electronic components is increased, thereby increasing the effective area of the circuit board. The reduction in the number of holes on the circuit board is also conducive to improving the structural strength of the circuit board itself, thereby improving the reliability and stability of the circuit board.
[0008] In some possible implementations, at least part of the limiting column is located in the first through hole. In this way, the circuit board realizes its own limiting through the cooperation between the first through hole and the limiting column. The inner wall of the first through hole can be a smooth inner wall, and the outer peripheral surface of the limiting column is also a smooth inner wall. The limiting column is located in the first through hole to realize the limiting of the circuit board. Therefore, the inner wall of the first through hole and the outer peripheral surface of the limiting column are both smooth wall surfaces, making the limiting of the circuit board more precise. Furthermore, the length of the limiting column is at least the length that can be extended into the first through hole, and the matching area between the limiting column and the connecting member can be increased. In this way, the connection between the limiting column and the connecting member is more stable, and the connection between the first structural member, the circuit board, and the first wall panel is also more stable.
[0009] In some possible implementations, at least part of the limiting column is also located in the second through hole. In this way, the first structural member realizes its own limiting through the cooperation between the second through hole and the limiting column. The inner wall of the second through hole can be a smooth inner wall, and the outer peripheral surface of the limiting column is also a smooth inner wall. The limiting column is located in the second through hole to realize the limiting of the first structural member. Therefore, the inner wall of the second through hole and the outer peripheral surface of the limiting column are both smooth wall surfaces, making the limiting of the first structural member more precise. Furthermore, the length of the limiting column is at least the length that can be extended into the second through hole, and the matching area between the limiting column and the connecting member can be increased. In this way, the connection between the limiting column and the connecting member is more stable, and the connection between the first structural member, the circuit board, and the first wall panel is also more stable.
[0010] In some possible implementations, the limiting post is disposed on the first wall plate, and the second through hole is disposed on the first structural member. When assembling the electronic device, usually the first wall plate is used as a reference for assembly, the limiting post can be disposed on the first wall plate, and the circuit board and the first structural member are installed in sequence, so as to facilitate the assembly of the electronic device.
[0011] In some possible implementations, the connector includes a first connecting rod and a fixing plate, the fixing plate is connected to one end of the first connecting rod, the first connecting rod is connected to the third through hole, the first connecting rod and the limiting column are integrally inserted into the first through hole and the second through hole, and the fixing plate is located on the side of the second through hole away from the circuit board. The connector is connected to the limiting column through the first connecting rod, and the fixing plate of the connector is used to fix the first structural member, the first structural member is fixed to the first wall panel by means of the connecting member and the limiting column, and also forms a limit to the circuit board in the first direction. The connector has a simple structure and is easy to process. In addition, the assembly method of the first connecting member, the limiting column, and the first structural member is also relatively simple, which is conducive to improving the assembly efficiency of the electronic device.
[0012] In some possible implementations, the limiting column is provided on the first wall plate, the second through hole is provided on the first structural member, and the first structural member contacts the fixing plate. In this way, the connecting member fixes the first structural member to the first wall plate through the fixing plate and the first connecting rod. The structure of the connecting member is simple, which facilitates the assembly of the circuit board and the first structural member, thereby improving the assembly efficiency of the circuit board and the first structural member. In addition, the connection between the connecting member and the first structural member, the circuit board and the first wall plate is relatively stable.
[0013] In some possible implementations, the limiting column is arranged on the first wall panel, and the second through hole is arranged on the first structural member. The electronic device also includes a second structural member, which is arranged on the side of the first structural member facing away from the circuit board, and the second structural member has a fourth through hole, and the fourth through hole is opposite to the third through hole. The first connecting rod is passed through the fourth through hole, and the fixing plate is located on the side of the second structural member facing away from the first structural member and contacts with the second structural member. In this way, the connecting member fixes the first structural member and the second structural member to the first wall panel through the fixing plate and the first connecting rod. The structure of the connecting member is simple, which facilitates the assembly of the circuit board, the first structural member and the second structural member, thereby improving the assembly efficiency of the circuit board, the first structural member and the second structural member. In addition, the connection method between the connecting member and the first structural member, the second structural member, the circuit board and the first wall panel is relatively stable.
[0014] In some possible implementations, the second structural member is a circuit board bracket, and the circuit board bracket connects the first wall plate and the circuit board.
[0015] In some possible implementations, the first through hole, the second through hole, and the third through hole are coaxial, so as to facilitate the assembly of the connecting member with the first structural member, the circuit board, and the first wall plate.
[0016] In some possible implementations, the first structural member is a metal structure, the surface of the circuit board has a grounding point, and the first structural member contacts and is electrically connected to the grounding point. In this way, the connector fixes the first structural member to the first wall plate, and the first structural member is fixed in the thickness direction, that is, the first direction. The first structural member contacts the circuit board, and the circuit board can be fixed in the first direction with the help of the first structural member. In addition, the limiting column is located in the first through hole of the circuit board, which realizes the limitation of the circuit board in its own length direction and width direction, and the circuit board is also fixed in all directions.
[0017] In some possible implementations, the surface of the first structural member has an elastic protrusion, and the elastic protrusion abuts against the grounding point. The protrusion is a portion of the fourth wall plate that protrudes toward the circuit board. The first structural member is fixed to the first wall plate through a connector. There is a locking force for fixing between the first structural member and the connector. When the fourth wall plate contacts the circuit board, the fixing portion squeezes the protrusion through this locking force. The setting of the protrusion can avoid the fourth wall plate from being in contact with the circuit board, thereby ensuring the stability of the electrical connection between the first structural member and the circuit board. In addition, by directly contacting the first structural member with the circuit board to achieve electrical connection, the electronic device can omit the setting of the grounding spring, thereby making room for the assembly of other structural members in the electronic device, thereby facilitating the assembly of other structural members in the electronic device.
[0018] In some possible implementations, a third structural member is provided on the surface of the circuit board facing the first structural member, the first structural member has a first notch that is recessed away from the circuit board, and at least a portion of the third structural member is accommodated in the first notch. In this way, the first notch leaves installation space for the second structural member, thereby increasing the area of the circuit board for arranging electronic components, thereby increasing the effective area of the circuit board.
[0019] In some possible implementations, the connector and the limiting column are threadedly matched. In this way, the first connecting rod and the limiting column are connected in a detachable manner, which facilitates the disassembly of various structural components in the electronic device during subsequent maintenance of the electronic device. In addition, compared with other connection methods such as bonding and welding, the first connecting rod and the limiting column are connected by threads, which is simple to assemble, easy to control the installation accuracy between the connector and the limiting column, and also easy to improve the assembly efficiency of the electronic device.
[0020] In some possible implementations, the connecting member is a screw, and the third through hole is a threaded hole that cooperates with the screw. In this way, the first connecting rod and the limiting column are connected in a detachable manner, which facilitates the disassembly of various structural parts in the electronic device during subsequent maintenance of the electronic device. In addition, compared with other connection methods such as bonding and welding, the first connecting rod and the limiting column are connected by threads, and the assembly method is simple, which is convenient for controlling the installation accuracy between the connecting member and the limiting column, and is also convenient for improving the assembly efficiency of the electronic device. In addition, the screws are usually standard parts, so there is no need to specially produce non-standard parts, which can also reduce the production cost of the electronic device.
[0021] In some possible implementations, the electronic device further includes a camera module, the camera module includes a camera body and a first bracket, the first bracket is arranged around the camera body and connected to the camera body, and the first structural member is the first bracket. In this way, only the connection structure between the first bracket and the connecting member needs to be designed, and there is no need to design the connection structure between the camera module and the connecting member, so that the camera module can be used in electronic devices of different models.
[0022] In some possible implementations, the electronic device further includes a middle frame, which includes a border and a first wall panel, and the border is arranged around an edge of the first wall panel to facilitate assembly of the first structural member. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] See also Figure 1 , Figure 1 A three-dimensional diagram of an electronic device 100 provided for some embodiments of the present application. This embodiment and the embodiments below are exemplified by taking the electronic device 100 as a mobile phone. The electronic device 100 is approximately in the shape of a rectangular plate. On this basis, in order to facilitate the description of the embodiments below, an XYZ coordinate system is established, and the width direction of the electronic device 100 is defined as the X-axis direction, the length direction of the electronic device 100 is defined as the Y-axis direction, and the thickness direction of the electronic device 100 is defined as the Z-axis direction. It can be understood that the coordinate system setting of the electronic device 100 can be flexibly set according to actual needs, and no specific limitation is made here. In some other embodiments, the shape of the electronic device 100 can also be a square flat plate, a circular flat plate, an elliptical flat plate, etc., which are not specifically limited here.
[0056] See also Figure 1 and Figure 2 , Figure 2 for Figure 1 The exploded structural diagram of the electronic device 100 is shown. In this embodiment, the electronic device 100 includes a screen 10, a housing 20, a circuit board 30 and a first structural member 40.
[0057] Understandably, Figure 1 and Figure 2 Only some components of the electronic device 100 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 and Figure 2 In some other examples, the electronic device 100 may not include the screen 10.
[0058] The screen 10 is used to display images, videos, etc. The screen 10 includes a light-transmitting cover plate 11 and a display screen 12 (English name: panel 1, also called a display panel). The light-transmitting cover plate 11 and the display screen 12 are stacked. The light-transmitting cover plate 11 is mainly used to protect the display screen 12 and prevent dust. The material of the light-transmitting cover plate 11 includes but is not limited to glass.
[0059] The housing 20 forms the housing of the electronic device 100 and is used to protect the internal electronic components of the electronic device 100. The housing 20 may include a back cover 21 and a frame 22. The back cover 21 is located on the side of the display screen 12 away from the light-transmitting cover plate 11, and is stacked and spaced with the light-transmitting cover plate 11 and the display screen 12. The frame 22 is located between the back cover 21 and the light-transmitting cover plate 11. The frame 22 is fixed on the back cover 21, and the light-transmitting cover plate 11, the back cover 21 and the frame 22 enclose an internal accommodation space of the electronic device 100. The internal accommodation space accommodates the display screen 12, the circuit board 30 and the first structural member 40.
[0060] In some embodiments, see Figure 2 The shell 20 may further include a middle plate 23. The middle plate 23 is disposed in the above-mentioned internal accommodating space, and the middle plate 23 is located on the side of the display screen 12 away from the light-transmitting cover plate 11. The edge of the middle plate 23 is fixed to the frame 22. The middle plate 23 divides the above-mentioned internal accommodating space into two independent spaces. One of the spaces is located between the light-transmitting cover plate 11 and the middle plate 23, and the display screen 12 is located in this part of the space. The other space is located between the middle plate 23 and the back cover 21, and the circuit board 30 and the first structural member 40 are accommodated in this part of the space. It should be noted that the whole formed by connecting the middle plate 23 and the frame 22 is also called the middle frame.
[0061] The middle plate 23 is a wall plate of the housing of the electronic device 100. In some embodiments, the middle plate 23 can form the first wall plate of the housing of the electronic device 100. In some other embodiments, the housing 20 may not include the middle plate 23. The back cover 21 is a wall plate of the housing of the electronic device 100. In this case, the back cover 21 can form the first wall plate of the housing of the electronic device 100. This application is described by taking the middle plate 23 as the first wall plate as an example, but this does not represent a special limitation on this application, that is, in some other embodiments, the back cover 21 can also be the first wall plate.
[0062] The circuit board 30 can be a host circuit board or other circuit boards. The circuit board 30 is fixed inside the electronic device 100 and is stacked with the back cover 21 and spaced apart. Figure 2 The circuit board 30 is located between the middle plate 23 and the back cover 21 and is fixed on the middle plate 23. The circuit board 30 has a first surface 31 and a second surface that are arranged opposite to each other, wherein the first surface 31 faces the back cover 21.
[0063] The circuit board 30 is used to set electronic components and realize electrical connection between the electronic components. The electronic components can be set on the first surface 31 or on the second surface 32. Among them, the electronic components can be, for example, a central processing unit (CPU), a graphics processing unit (GPU), a universal storage (UFS), a receiver, a speaker module, a camera module, and a flash module. The first structural member 40 can be one of the above electronic components, and the first structural member 40 is located on the first surface 31. The following is an example of the first structural member being a camera module.
[0064] The camera module 40 is used to realize the shooting of videos or images. The camera module 40 includes but is not limited to a main camera, a wide-angle camera and a telephoto camera, and the structural form of the camera module 40 includes but is not limited to an upright type and a periscope type. The camera module 40 can be a front camera or a rear camera. When the camera module 40 is a rear camera, the camera module 40 is located between the middle plate 23 and the back cover 21. When the camera module 40 is a front camera, the camera module 40 is located between the middle plate 23 and the screen 10. The embodiment of the present application is described by taking the camera module 40 as a rear camera as an example.
[0065] See also Figure 3 , Figure 3 for Figure 2A structural schematic diagram of the connection of the camera module 40, the circuit board 30 and the middle plate shown. The camera module 40 includes a camera body 41 and a first bracket 42, and the first bracket 42 is used to fix the camera body 41 in the accommodating space of the electronic device 100. Among them, the camera body 41 is a main body for realizing video or image shooting. The camera body 41 has a light incident surface, and the light incident surface can be the light incident surface of the optical lens in the camera body 41. The light incident surface of the camera body 41 faces the back cover 21. On this basis, a light-transmitting portion 211 is provided on the back cover 21, and the light incident surface of the camera body 41 faces the light-transmitting portion 211, so that the external scene light can pass through the light-transmitting portion 211 into the camera body 41, so as to realize the shooting of external video or image of the electronic device.
[0066] The following is a detailed description of how the camera module 40 is installed in the housing 20. The camera module 40 is fixed to the middle plate, and the circuit board 30 is also fixed to the middle plate. For example, the circuit board 30 has a through hole, and the camera module 40 is inserted into the through hole and fixed to the middle plate.
[0067] See also Figure 4 , Figure 4 for Figure 3 The schematic diagram of the structure of the first bracket 42 in the camera module 40 is shown. The first bracket 42 can be annular, and the camera body 41 can be arranged in the inner cavity 425 of the first bracket 42. In some embodiments, the first bracket 42 can be processed by a two-color injection molding process, that is, by injecting two plastics with different degrees of hardness into the same mold, wherein the hardness of the side wall of the part close to the inner cavity 425 is less than the hardness of the rest of the part, thereby improving the assembly performance of the first bracket 42. On this basis, the outer peripheral wall of the camera body 41 and the inner peripheral wall of the first bracket 42 are interference fit to install and fix the camera body 41 on the first bracket 42.
[0068] In some other embodiments, the first bracket 42 may also be a metal structure, and the camera body 41 may be connected to the first bracket 42 by conductive glue, welding, or the like. In this way, the first bracket 42 may be electrically connected to adjacent structural parts and the circuit board 30 to achieve grounding of the camera module 40.
[0069] For details, please continue to refer to Figure 4 The first bracket 42 may include a first side wall 421 and a second side wall 422 that are opposite and spaced apart, and a third side wall 423 and a fourth side wall 424 that are opposite and spaced apart. The first side wall 421, the second side wall 422, the third side wall 423 and the fourth side wall 424 surround an inner cavity 425 of the first bracket 42. Figure 4In the illustrated embodiment, the first side wall 421 and the second side wall 422 are arranged along the Y-axis direction, and the third side wall 423 and the fourth side wall 424 are distributed along the X-axis. Of course, in other embodiments, the first side wall 421, the second side wall 422, the third side wall 423 and the fourth side wall 424 may also be arranged along other directions, and the present application does not limit this. In other embodiments, the shape of the first bracket 42 may not be annular, and the first bracket 42 may also be fixed to the outer peripheral side of the camera body 41 by glue or tape. The following text takes the first bracket 42 as an annular shape as an example for introduction.
[0070] The first bracket 42 also has a second through hole 427, and the number of the second through holes 427 can be one, two, three, four, etc. In some embodiments, the second through hole 427 is disposed on the surface of the first side wall 421 facing the circuit board 30, and the surface of the second side wall 422 facing the circuit board 30. The thickness of the first side wall 421 and the thickness of the second side wall 422 need to meet the thickness required to set the second through hole 427. In this way, the greater thickness of the first side wall 421 can ensure the structural strength of the first bracket 42.
[0071] However, due to the development of electronic devices 100 being thinner and lighter, the first side wall 421 needs to be thinned. Figure 4 The second connection part 426 can be arranged on the outer wall surface of the first side wall 421, and the outer wall surface of the first side wall 421 refers to the wall surface of the first side wall 421 that is away from the inner cavity 425 of the first bracket 42. The second connection part 426 protrudes from the outer wall surface of the first side wall 421, and a second through hole 427 is arranged on the connection part. In this way, the thickness of the first side wall 421 does not need to adapt to the arrangement of the second through hole 427, so as to realize the lightness and thinness of the first bracket 42.
[0072] See also Figure 5 , Figure 5 for Figure 3 The schematic diagram of the structure of the first wall plate 24 is shown. The first wall plate 24 includes a third surface 241 and a fourth surface 242 which are arranged opposite to each other, wherein the third surface 241 is the surface of the first wall plate 24 facing the circuit board 30. The limiting posts 243 are arranged on the third surface 241, and the number of the limiting posts 243 is equal to the number of the second through holes 427. The number of the limiting posts 243 can also be one, two, three, four, and so on. This embodiment is described by taking the number of the limiting posts 243 as two as an example, and taking the second through holes 427 arranged on the first side wall 421 and the second side wall 422 as an example. One of the second through holes 427 is arranged at one end of the first side wall 421 close to the third side wall 423, and the other second through hole 427 is arranged at one end of the second side wall 422 close to the fourth side wall 424. In this way, the accuracy of positioning the camera module 40 can be further improved.
[0073] The limiting column 243 may be columnar or block-shaped. The embodiment of the present application is described by taking the limiting column 243 as a columnar shape as an example, and the axis of the limiting column 243 is perpendicular to the third surface 241. In some embodiments, the limiting column 243 and the first wall plate 24 are an integral structure. In some other embodiments, the limiting column 243 and the first wall plate 24 may also be independent structures, and the limiting column 243 may be connected to the first wall plate 24 by bonding, welding, etc. The embodiment of the present application is described by taking the limiting column 243 and the first wall plate 24 as an integral structure as an example.
[0074] To ensure the cooperation between the limiting column 243 and the second through hole 427, please refer to Figure 6 , Figure 6 for Figure 3 The schematic diagram of the structure of the circuit board 30 is shown. A first through hole 33 is provided on the circuit board 30 at a position opposite to the limiting column 243. When the camera module 40 is assembled, the limiting column 243 passes through the first through hole 33 and cooperates with the second through hole 427 to complete the limiting of the camera module 40. The limiting here includes limiting in two directions. The limiting column 243 limits the limiting of the camera module 40 in the X-axis direction and the Y-axis direction.
[0075] Please also read Figure 5 and Figure 6 The circuit board 30 and the middle plate also need to be fixedly connected. The first wall plate 24 has a first threaded hole 244, and the circuit board 30 has a second threaded hole 34 opposite to the first threaded hole 244. Screws, bolts and other threaded connectors 50 are arranged in the first threaded hole 244 and the second threaded hole 34 to fix the circuit board 30 to the middle plate. Figure 5 The first wall plate 24 shown only shows a first threaded hole 244. Figure 6 The circuit board 30 shown also only illustrates one second threaded hole 34 , and the number of the first threaded holes 244 may also be two, three, four, etc. The number of the first threaded holes 244 is consistent with the number of the first threaded holes 244 .
[0076] From the above content, it can be known that there are many openings on the circuit board 30, including holes for avoiding the limit posts 243 and holes for fixing the circuit board 30. In this way, the effective area on the circuit board 30 that can be used to set electronic components is greatly reduced, and the structural strength of the circuit board 30 will also be affected.
[0077] In order to solve the above problems, the embodiment of the present application further provides an electronic device 100, which aims to reduce the openings on the circuit board 30 to increase the effective area on the circuit board 30, and also improve the structural strength of the circuit board 30. The difference between the embodiment of the present application and the above embodiment is mainly that the structure of the limit post 243 in the present embodiment is different from the structure of the limit post 243 in the above embodiment.
[0078] For details, please refer to Figure 7 , Figure 7 for Figure 2 Another structural schematic diagram of the camera module 40, the circuit board 30 and the middle plate is shown. The electronic device 100 includes a housing 20, a circuit board 30, a first structural member 40 and a connecting member 50. The housing 20 includes a first wall plate 24. The circuit board 30 is stacked with the first wall plate 24. The circuit board 30 has a first through hole 33. The arrangement direction of the first wall plate 24 and the circuit board 30 is a first direction, that is, Figure 7 The first structural member 40 is located on the side of the circuit board 30 away from the first wall plate 24. One of the first structural member 40 and the first wall plate 24 has a limiting column 243, and the other has a second through hole. At least part of the limiting column is located in the first through hole 33. This part of the technical features of the embodiment of the present application is consistent with the above content. This embodiment and the following embodiments are also introduced by taking the first structural member 40 as a camera module 40 as an example, and also taking the limiting column set on the first wall plate 24 and the second through hole set on the first structural member 40 as an example for explanation.
[0079] It is worth noting that the following contents are the differences between the embodiments of this application and the above contents, please refer to Figure 8 , Figure 8 for Figure 7 The first wall plate 24 is shown in the structural diagram. The limiting column 243 has a third through hole 2431. Fig. 9 and Fig.10 , Fig. 9 for Figure 7 Cross-sectional view at AA in the middle; Fig.10 for Fig. 9 The exploded view of the first structural member 40, the circuit board 30 and the first wall plate 24 at AA is shown. The axis of the first through hole 33, the axis of the second through hole 427 and the axis of the third through hole 2431 are parallel to each other. The connecting member 50 passes through the second through hole 427 and extends into the third through hole 2431, and the connecting member 50 connects the housing 20 and the first structural member 40.
[0080] In this way, the limiting column 243 can play two roles. First, the first structural member 40 is limited by the limiting column 243. The limiting here includes the limiting of the first structural member 40 in the width direction, length direction and thickness direction by the limiting column 243. Figure 8 The first structural member 40 is fixed to the first wall plate 24 through the limiting column 243. Second, the limiting column 243 and one of the connecting members 50 pass through the first through hole 33 to limit the circuit board 30. The limiting here includes the limiting of the circuit board 30 by the limiting column 243 in its own length direction and width direction. Figure 8 In the first direction, the circuit board 30 is in contact with at least part of the first structural member 40. After the first structural member 40 is connected to the housing 20 through the connecting member 50, the circuit board 30 located between the first structural member 40 and the first wall plate 24 is limited in its thickness direction by means of the first structural member 40 and the first wall plate 24. Figure 8 The X-axis direction.
[0081] In summary, the first structural member 40 is fixed to the first wall plate 24 through the limiting column 243, and the circuit board 30 can also be fixed to the first wall plate 24 through the limiting column 243, and the first structural member 40 and the circuit board 30 can be fixed to the first wall plate 24 by sharing the first through hole 33. Therefore, the number of holes on the circuit board 30 used to fix itself and the number of holes used to fix the first structural member 40 are reduced, and the area on the circuit board 30 used to connect other electronic components is increased, thereby increasing the effective area of the circuit board 30. The reduction in the number of holes on the circuit board 30 is also conducive to improving the structural strength of the circuit board 30 itself, thereby improving the reliability and stability of the circuit board 30.
[0082] Please continue reading Fig. 9 In some embodiments, at least part of the limiting column 243 is located in the first through hole 33. In this way, the circuit board 30 can achieve its own limiting through the cooperation between the first through hole 33 and the limiting column 243. The inner wall of the first through hole 33 can be a smooth inner wall, and the outer peripheral surface of the limiting column 243 is also a smooth inner wall. The limiting column 243 is located in the first through hole 33 to achieve the limiting of the circuit board 30. Therefore, the inner wall of the first through hole 33 and the outer peripheral surface of the limiting column 243 are both smooth wall surfaces, so that the limiting of the circuit board 30 is more accurate. Further, the length of the limiting column 243 is at least the length that can be inserted into the first through hole 33, and the matching area between the limiting column 243 and the connecting member 50 can be increased. In this way, the connection between the limiting column and the connecting member 50 is more stable, and the connection between the first structural member 40, the circuit board 30, and the first wall plate 24 is also more stable.
[0083] Please continue reading Fig. 9In some embodiments, at least part of the limiting column 243 is also located in the second through hole 427. In this way, the first structural member 40 realizes its own limiting through the cooperation between the second through hole 427 and the limiting column 243. The inner wall of the second through hole 427 can be a smooth inner wall, and the outer peripheral surface of the limiting column 243 is also a smooth inner wall. The limiting column 243 is located in the second through hole 427 to realize the limiting of the first structural member 40. Therefore, the inner wall of the second through hole 427 and the outer peripheral surface of the limiting column 243 are both smooth wall surfaces, so that the limiting of the first structural member 40 is more accurate. Further, the length of the limiting column 243 is at least the length that can be extended into the second through hole 427, and the matching area between the limiting column 243 and the connecting member 50 can be increased. In this way, the connection between the limiting column and the connecting member 50 is more stable, and the connection between the first structural member 40, the circuit board 30, and the first wall plate 24 is also more stable.
[0084] The following is a detailed description of the connection method of the connector 50 with the housing 20 and the first structural member 40. The connector 50 and the limiting column 243 can be connected by bonding, welding, interference fit, or threaded connection. The embodiment of the present application is described by taking the connector 50 and the limiting column 243 being connected by threaded connection as an example.
[0085] See also Fig.11 , Fig.11 for Fig. 9 An enlarged view of point A is shown. Specifically, the connecting member 50 includes a first connecting rod 51 and a fixing plate 52. The first connecting rod 51 may be rod-shaped, column-shaped, or block-shaped. The fixing plate 52 may be plate-shaped. The fixing plate 52 is connected to one end of the first connecting rod 51. In some embodiments, the first connecting rod 51 and the fixing plate 52 may be an integral structural member. In other embodiments, the first connecting rod 51 and the fixing plate 52 may also be independent structural members, and the first connecting rod 51 and the fixing plate 52 are connected by welding, bonding, or the like.
[0086] Part of the first connecting rod 51 is located in the third through hole 2431, and the fixing plate 52 is located on the side of the second through hole 427 away from the circuit board 30. The first structural member 40 also includes a second wall plate 428 surrounding the second through hole 427, the second wall plate 428 is located between the limiting column 243 and the fixing plate 52, and the second wall plate 428 is in contact with the fixing plate 52. The definition of "contact" here includes, first, the second wall plate 428 is connected to the fixing plate 52 and there is no relative squeezing force between the second wall plate 428 and the fixing plate 52; second, the second wall plate 428 is connected to the fixing plate 52 and there is a relative squeezing force between the second wall plate 428 and the fixing plate 52, that is, the second wall plate 428 is in contact with the fixing plate 52.
[0087] A part of the connector 50 is connected to the limiting column 243, that is, connected to the limiting column 243 through the first connecting rod 51. The first connecting rod 51 and the limiting column 243 can be connected by bonding, welding, threaded connection, etc. In this embodiment, the first connecting rod 51 and the limiting column 243 are connected by threaded connection as an example. Specifically, a thread is provided on the outer peripheral surface of the first connecting rod 51, and a thread matching with the first connecting rod 51 is provided on the inner wall of the third through hole 2431, so as to achieve the threaded matching between the first connecting rod 51 and the third through hole 2431. In this way, the first connecting rod 51 and the limiting column 243 are connected by a detachable connection method, and it is convenient to disassemble various structural parts in the electronic device 100 in the subsequent maintenance of the electronic device 100. In addition, compared with other connection methods such as bonding and welding, the first connecting rod 51 and the limiting column 243 are connected by threading, and the assembly method is simple, which is convenient for controlling the installation accuracy between the connector 50 and the limiting column 243, and is also convenient for improving the assembly efficiency of the electronic device 100.
[0088] The other part of the connecting portion is connected to the first structural member 40, that is, connected to the second wall plate 428 through the fixing plate 52. The second wall plate 428 is the end surface of the first structural member 40 facing away from the circuit board 30, and the second wall plate 428 is arranged around the second through hole 427, and the fixing plate 52 contacts the second wall plate 428.
[0089] In summary, the connector 50 fixes the first structural member 40 to the first wall plate 24 through the fixing plate 52 and the first connecting rod 51. The connector 50 has a simple structure and is convenient for assembling the circuit board 30 and the first structural member 40, thereby improving the assembly efficiency of the circuit board 30 and the first structural member 40. In addition, the connection between the connector 50 and the first structural member 40, the circuit board 30 and the first wall plate 24 is relatively stable. The connector 50 fixes the first structural member 40 to the first wall plate 24, and realizes the all-round limitation of the first structural member 40, that is, the limitation of the first structural member 40 in its own width direction, length direction and thickness direction, that is, Fig.11 The X-axis direction, Y-axis direction and Z-axis direction of the circuit board 30. The circuit board 30 can also be fixed to the first wall plate 24 by the cooperation of the limiting column 243 and the first structural member 40, and the first structural member 40 and the circuit board 30 can be fixed to the first wall plate 24 by sharing the first through hole 33. Therefore, the number of openings on the circuit board 30 for fixing itself and the number of openings for fixing the first structural member 40 are reduced, and the area on the circuit board 30 for connecting other electronic components is increased, thereby increasing the effective area of the circuit board 30. The reduction in the number of openings on the circuit board 30 is also conducive to improving the structural strength of the circuit board 30 itself, thereby improving the reliability and stability of the circuit board 30.
[0090] Please continue reading Fig.11In some embodiments, the first structural member 40 further includes a fourth wall plate 429 surrounding the limiting column 243, and the fourth wall plate 429 has a fourth wall plate 429 facing the circuit board 30, and the fourth wall plate 429 contacts the circuit board 30. In this way, the connecting member 50 fixes the first structural member 40 to the first wall plate 24, and the first structural member 40 is fixed in the thickness direction, that is, the first direction. The first structural member 40 contacts the circuit board 30, and the circuit board 30 can be fixed in the first direction with the help of the first structural member 40, and the limiting column 243 is located in the first through hole 33 of the circuit board 30, which also realizes the limitation of the circuit board 30 in the length direction and width direction, and the circuit board 30 is also fixed in all directions.
[0091] Therefore, only the first through hole 33 is provided on the circuit board 30, so that the first structural member 40 and the circuit board 30 can be fixed, the number of openings on the circuit board 30 for fixing itself and the number of openings for fixing the first structural member 40 can be reduced, and the area on the circuit board 30 for connecting other electronic components can be increased, thereby increasing the effective area of the circuit board 30. The reduction in the number of openings on the circuit board 30 is also conducive to improving the structural strength of the circuit board 30 itself, thereby improving the reliability and stability of the circuit board 30.
[0092] See also Fig.12 , Fig.12 for Fig. 9 Another enlarged view of A is shown. In some embodiments, when the first structural member 40 is a metal structure, in order to ensure the electrical connection between the first structural member 40 and the circuit board 30 and realize the grounding of the first structural member 40, the fourth wall plate 429 has a protrusion 430, and the protrusion 430 is an elastic material structure, and the protrusion 430 is in contact with the circuit board 30. The protrusion 430 is a portion of the fourth wall plate 429 that protrudes toward the circuit board 30. The first structural member 40 is fixed to the first wall plate 24 through the connecting member 50. There is a locking force for fixing between the first structural member 40 and the connecting member 50. When the fourth wall plate 429 contacts the circuit board 30, the fixing portion squeezes the protrusion 430 through this part of the locking force. The setting of the protrusion 430 can avoid the fourth wall plate 429 from being in contact with the circuit board 30, and ensure the stability of the electrical connection between the first structural member 40 and the circuit board 30. Furthermore, by directly contacting the first structural member 40 with the circuit board 30 to achieve electrical connection, the electronic device 100 can omit the provision of a grounding spring, thereby freeing up space for assembling other structural members in the electronic device 100 and facilitating the assembly of other structural members in the electronic device 100.
[0093] See also Fig.13 , Fig.13 for Fig. 9A is shown in an enlarged view. In some embodiments, a third structural member 70 is provided on the circuit board 30, and the third structural member 70 can be a central processing unit (CPU), a graphics processing unit (GPU), a universal storage (UFS), a receiver, a speaker module, and a flash module. The fourth wall plate 429 has a first notch 431 that is recessed away from the circuit board 30, and the third structural member 70 is located in the first notch 431. In this way, the first notch 431 is used to avoid the installation space for the third structural member 70, thereby increasing the area of the circuit board 30 for setting electronic components, thereby increasing the effective area of the circuit board 30.
[0094] See also Fig.14 , Fig.15 and Fig.16 , Fig.14 for Figure 2 Another structural schematic diagram of the camera module 40, the circuit board 30 and the middle board connected as shown; Fig.15 for Fig.14 Cross-section at the middle BB; Fig.16 for Fig.15 In some possible implementations, the electronic device 100 further includes a second structural member 60, which is located on a side of the first structural member 40 away from the circuit board 30. In the first direction, the second structural member 60 is in contact with at least part of the first structural member 40. The second structural member 60 has a fourth through hole 61, and the axis of the fourth through hole 61 is parallel to the axis of the third through hole 2431. The second structural member 60 has a third wall plate 62, which is located between the first structural member 40 and the fixing plate 52. One side surface of the third wall plate 62 is in contact with the first structural member 40, and the other side surface of the first wall plate 24 is in contact with the fixing plate 52.
[0095] The second structural member 60 can be a circuit board 30 bracket 42, and the circuit board 30 bracket 42 is located on one side of the circuit board 30. The circuit board 30 is located between the circuit board 30 bracket 42 and the first wall panel 24, forming a limit for the circuit board 30 in its own thickness direction. The circuit board 30 bracket 42 is fixed by the cooperation of the connecting member 50 and the limiting column 243, thereby improving the stability of the circuit board 30 bracket 42.
[0096] In this way, the connecting member 50 fixes the first structural member 40 and the second structural member 60 to the first wall plate 24 through the fixing plate 52 and the first connecting rod 51. The structure of the connecting member 50 is simple, which facilitates the assembly of the circuit board 30, the first structural member 40 and the second structural member 60, thereby improving the assembly efficiency of the circuit board 30, the first structural member 40 and the second structural member 60. In addition, the connection method of the connecting member 50 with the first structural member 40, the second structural member 60, the circuit board 30 and the first wall plate 24 is relatively stable.
[0097] In some embodiments, the first through hole 33, the second through hole 427 and the third through hole 2431 are coaxial. In this way, the assembly of the connecting member 50 with the first structural member 40, the circuit board 30 and the first wall plate 24 is facilitated.
[0098] In some other embodiments, the limiting column 243 can be arranged on the first structural member 40, and the second through hole 427 can be arranged on the first structural member 40. In this way, the flexibility of the setting position of the limiting column 243 and the second through hole 427 is improved, and the setting position of the limiting column 243 and the second through hole 427 can be determined according to the actual assembly situation of the electronic device 100. Specifically, when the electronic device 100 is assembled, when the housing 20 is used as a reference, the limiting column can be arranged on the first wall plate 24, and the circuit board 30 and the first structural member 40 are installed in sequence, which is convenient for the assembly of the electronic device 100. When the electronic device 100 is assembled, when the first structural member 40 is used as a reference, the limiting column can be arranged on the first structural member 40, and the circuit board 30 and the housing 20 are installed in sequence, which is convenient for the assembly of the electronic device 100.
