Description

An electronic device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on March 30, 2024, with application number 202420670289.7 and utility model name “An Electronic Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art

[0003] Some structural components in electronic devices such as mobile phones and tablets are positioned in conjunction with circuit boards and midframes. For example, these components can be camera modules or speaker modules. These components are assembled within the electronic device and need to be positioned. This requires holes in the circuit board to accommodate these positioning. Furthermore, holes are also required to secure the circuit board to the midframe. Consequently, the large number of holes in the circuit board reduces the area available for placement of other electronic components, further reducing the effective usable area of ​​the circuit board.

[0004] Utility Model Content

[0005] An embodiment of the present application provides an electronic device for reducing openings in a circuit board to increase the effective usable area of ​​the circuit board.

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

[0007] An embodiment of the present application provides an electronic device comprising a first wall panel, a circuit board, a first structural member, and a connector. The circuit board is stacked with the first wall panel, the circuit board having a first through hole, and the first wall panel and the circuit board are arranged in a first direction. The first structural member is disposed on a side of the circuit board facing away from the first wall panel. One of the first structural member and the first wall panel has a limiting post, and the other has a second through hole. The limiting post has a third through hole, and the first through hole, the second through hole, and the third through hole are opposed to each other in the first direction. The connector is connected to the third through hole, and the connector and the limiting post are integrally disposed through the first through hole and the second through hole to connect the first wall panel, the circuit board, and the first structural member.

[0008] 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 the 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 achieve the limitation of the circuit board. The limitation here includes the limitation of the circuit board in the 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 the thickness direction with the help of the first structural member and the first wall panel.

[0009] In summary, both the first structural member and the circuit board can be secured to the first wall panel via the retaining posts, and the first structural member and the circuit board share a common first through-hole for securing the first wall panel. Consequently, the number of holes on the circuit board used to secure the circuit board itself and the number of holes used to secure the first structural member are reduced, increasing the area available for connecting other electronic components and thereby increasing the effective area of ​​the circuit board. This reduction in the number of holes on the circuit board also helps improve the structural strength of the circuit board, thereby enhancing its reliability and stability.

[0010] In some possible implementations, at least a portion of the limiting post is located within the first through-hole. In this way, the circuit board achieves its own positional limitation through the cooperation between the first through-hole and the limiting post. The inner wall of the first through-hole can be a smooth inner wall, and the outer peripheral surface of the limiting post is also a smooth inner wall. The limiting post is located within the first through-hole to limit the circuit board. Therefore, the inner wall of the first through-hole and the outer peripheral surface of the limiting post are both smooth wall surfaces, making the positioning of the circuit board more precise. Furthermore, the length of the limiting post is at least the length that can be inserted into the first through-hole, and the mating area between the limiting post and the connector can be increased. In this way, the connection between the limiting post and the connector is more stable, and the connection between the first structural member, the circuit board, and the first wall panel is also more stable.

[0011] In some possible implementations, at least a portion of the limiting post is also located within the second through-hole. In this way, the first structural member achieves its own positioning through the cooperation between the second through-hole and the limiting post. The inner wall of the second through-hole can be a smooth inner wall, and the outer peripheral surface of the limiting post is also a smooth inner wall. The limiting post is located within the second through-hole to achieve positioning of the first structural member. Therefore, both the inner wall of the second through-hole and the outer peripheral surface of the limiting post are smooth wall surfaces, making positioning of the first structural member more precise. Furthermore, the length of the limiting post is at least the length that can be inserted into the second through-hole, and the matching area between the limiting post and the connector can be increased. In this way, the connection between the limiting post and the connector is more stable, and the connection between the first structural member, the circuit board, and the first wall panel is also more stable.

[0012] In some possible implementations, the limiting post is provided on the first wall panel, and the second through hole is provided on the first structural member. When assembling the electronic device, which is usually assembled based on the first wall panel, the limiting post can be provided on the first wall panel, and the circuit board and the first structural member can be installed in sequence, thereby facilitating the assembly of the electronic device.

[0013] 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 facing 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 with the aid of the connector and the limiting column, and also forms a limit for 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 connector, the limiting column, and the first structural member is also relatively simple, which is conducive to improving the assembly efficiency of the electronic device.

[0014] In some possible implementations, the limiting post is provided on the first wall panel, the second through-hole is provided on the first structural member, and the first structural member contacts the fixing plate. In this manner, the connector secures the first structural member to the first wall panel via the fixing plate and the first connecting rod. The connector has a simple structure, facilitating assembly of the circuit board and the first structural member, thereby improving assembly efficiency. Furthermore, the connection between the connector, the first structural member, the circuit board, and the first wall panel is relatively stable.

[0015] In some possible implementations, the limiting column is provided on the first wall panel, and the second through hole is provided on the first structural member. The electronic device also includes a second structural member, which is provided on the side of the first structural member facing away from the circuit board. 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 the second structural member. In this way, the connecting member fixes both 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.

[0016] In some possible implementations, the second structural member is a circuit board bracket, which connects the first wall panel and the circuit board.

[0017] In some possible implementations, the first through hole, the second through hole, and the third through hole are coaxial, so as to facilitate assembly of the connecting member with the first structural member, the circuit board, and the first wall panel.

[0018] In some possible implementations, the first structural member is a metal structure, and the surface of the circuit board has a grounding point, with the first structural member in contact with and electrically connected to the grounding point. In this way, the connector secures the first structural member to the first wall panel, securing the first structural member in its thickness direction, i.e., the first direction. The first structural member contacts the circuit board, securing the circuit board in the first direction with the aid of the first structural member. Furthermore, the limiting post is located within the first through-hole of the circuit board, thereby limiting the circuit board in both its length and width directions, achieving full-scale fixation of the circuit board.

[0019] In some possible implementations, the surface of the first structural member includes an elastic protrusion that abuts a grounding point. The protrusion is a portion of the fourth wall panel that protrudes toward the circuit board. The first structural member is secured to the first wall panel via a connector. A locking force is exerted between the first structural member and the connector to secure the connection. When the fourth wall panel contacts the circuit board, the fixing portion compresses the protrusion through this locking force. The provision of the protrusion prevents incomplete contact between the fourth wall panel and the circuit board, thereby ensuring the stability of the electrical connection between the first structural member and the circuit board. Furthermore, by achieving electrical connection through direct contact between the first structural member and the circuit board, the electronic device can omit the provision of a grounding spring, thereby freeing up space for the assembly of other structural components within the electronic device, thereby facilitating the assembly of other structural components within the electronic device.

[0020] 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 recessed away from the circuit board, and at least a portion of the third structural member is accommodated within the first notch. In this way, the first notch provides mounting space for the second structural member, increasing the area of ​​the circuit board for mounting electronic components and, in turn, increasing the effective area of ​​the circuit board.

[0021] In some possible implementations, the connecting member and the retaining post are threadedly engaged. This allows for a detachable connection between the first connecting rod and the retaining post, facilitating disassembly of various components within the electronic device during subsequent repairs. Furthermore, compared to other connection methods such as bonding and welding, the threaded connection between the first connecting rod and the retaining post simplifies assembly, facilitates control over the installation precision between the connecting member and the retaining post, and improves assembly efficiency of the electronic device.

[0022] 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 via a detachable connection method, 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 via a threaded connection, which simplifies the assembly method, facilitates the control of the installation accuracy between the connecting member and the limiting column, and also facilitates improving the assembly efficiency of the electronic device. In addition, screws are generally standard parts, eliminating the need to specially produce non-standard parts, which can also reduce the production cost of the electronic device.

[0023] In some possible implementations, the electronic device further includes a camera module, which includes a camera body and a first bracket. The first bracket is disposed around a perimeter of the camera body and connected to the camera body, and the first structural member is the first bracket. In this manner, only the connection structure between the first bracket and the connector needs to be designed, eliminating the need to design the connection structure between the camera module and the connector. This allows the camera module to be universally compatible with different models of electronic devices.

[0024] In some possible implementations, the electronic device further includes a middle frame, which includes a border and a first wall panel. 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

[0049] Please refer to Figure 1, which is a three-dimensional diagram of the electronic device 100 provided in 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.

[0050] 1 and 2 , FIG2 is a schematic diagram of the exploded structure of the electronic device 100 shown in FIG1 . In this embodiment, the electronic device 100 includes a screen 10 , a housing 20 , a circuit board 30 and a first structural member 40 .

[0051] 1 and 2 only schematically illustrate some components of the electronic device 100, and the actual shape, size, position, and structure of these components are not limited by FIG1 and 2. In other examples, the electronic device 100 may not include the screen 10.

[0052] Screen 10 is used to display images, videos, and the like. Screen 10 includes a translucent cover plate 11 and a display screen 12 (also known as a display panel). Translucent cover plate 11 and display screen 12 are stacked. Translucent cover plate 11 primarily protects display screen 12 and provides dust protection. Translucent cover plate 11 can be made of, but is not limited to, glass.

[0053] 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 transparent cover plate 11, and is stacked with the transparent cover plate 11 and the display screen 12 and spaced apart. The frame 22 is located between the back cover 21 and the transparent cover plate 11. The frame 22 is fixed to the back cover 21, and the transparent cover plate 11, the back cover 21 and the frame 22 form an internal storage space of the electronic device 100. The internal storage space accommodates the display screen 12, the circuit board 30 and the first structural member 40.

[0054] In some embodiments, referring to FIG2 , the shell 20 may further include a middle plate 23. The middle plate 23 is disposed in the above-mentioned internal accommodation 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 accommodation 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.

[0055] The middle plate 23 is a wall panel of the housing of the electronic device 100. In some embodiments, the middle plate 23 can form the first wall panel of the housing of the electronic device 100. In other embodiments, the housing 20 may not include the middle plate 23. The back cover 21 is a wall panel of the housing of the electronic device 100. In this case, the back cover 21 can form the first wall panel of the housing of the electronic device 100. This application uses the middle plate 23 as the first wall panel as an example for description, but this does not constitute a special limitation of this application. That is, in other embodiments, the back cover 21 can also be the first wall panel.

[0056] The circuit board 30 can be a host circuit board or another circuit board. The circuit board 30 is fixed inside the electronic device 100 and is stacked and spaced apart from the back cover 21. In some embodiments, as shown in FIG2 , the circuit board 30 is located between the middle plate 23 and the back cover 21 and is fixed to the middle plate 23. The circuit board 30 has a first surface 31 and a second surface that are disposed opposite each other, with the first surface 31 facing the back cover 21.

[0057] The circuit board 30 is used to mount electronic components and achieve electrical connections between them. The electronic components can be mounted on either the first surface 31 or the second surface 32. Examples of these electronic components include a central processing unit (CPU), a graphics processing unit (GPU), a universal flash storage (UFS), an earpiece, a speaker module, a camera module, and a flash module. The first structural member 40 can be one of these electronic components, and is located on the first surface 31. The following description uses a camera module as an example.

[0058] The camera module 40 is used to capture 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 forms of the camera module 40 include but are not limited to upright and periscope types. The camera module 40 can be a front-facing camera or a rear-facing camera. When the camera module 40 is a rear-facing 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-facing camera, the camera module 40 is located between the middle plate 23 and the screen 10. The embodiments of the present application are described using the example of the camera module 40 being a rear-facing camera.

[0059] Please refer to Figure 3, which is a structural diagram of the connection between the camera module 40, the circuit board 30 and the middle plate shown in Figure 2. 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 body for realizing video or image shooting. The camera body 41 has a light incident surface, which 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 light of the external scene 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.

[0060] The following describes the specific method for installing the camera module 40 within the housing 20. The camera module 40 is fixed to the midboard, and the circuit board 30 is also fixed to the midboard. 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 midboard.

[0061] Please refer to Figure 4, which is a schematic diagram of the structure of the first bracket 42 in the camera module 40 shown in Figure 3. The first bracket 42 can be annular, and the camera body 41 can be disposed 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 hardness into the same mold, wherein the hardness of the side wall near the inner cavity 425 is less than that of the remaining 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.

[0062] 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.

[0063] Specifically, referring to FIG. 4 , the first bracket 42 may include a first sidewall 421 and a second sidewall 422 disposed opposite and spaced apart from each other, as well as a third sidewall 423 and a fourth sidewall 424 disposed opposite and spaced apart from each other. The first sidewall 421, the second sidewall 422, the third sidewall 423, and the fourth sidewall 424 enclose an inner cavity 425 of the first bracket 42. In the embodiment shown in FIG. 4 , the first sidewall 421 and the second sidewall 422 are arranged along the Y-axis, while the third sidewall 423 and the fourth sidewall 424 are arranged along the X-axis. Of course, in other embodiments, the first sidewall 421, the second sidewall 422, the third sidewall 423, and the fourth sidewall 424 may be arranged along other directions, and this is not limited in this application. In other embodiments, the shape of the first bracket 42 may not be annular, and the first bracket 42 may be secured to the outer periphery of the camera body 41 using glue or tape. The following description uses the annular shape of the first bracket 42 as an example.

[0064] The first bracket 42 further has second through holes 427 , and the number of second through holes 427 can be one, two, three, four, etc. In some embodiments, the second through holes 427 are provided on the surface of the first side wall 421 facing the circuit board 30 , and on 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 be sufficient to accommodate the second through holes 427 . In this way, the greater thickness of the first side wall 421 can ensure the structural strength of the first bracket 42 .

[0065] However, due to the increasing trend toward thinner and lighter electronic devices 100, it is necessary to reduce the thickness of the first sidewall 421. In other embodiments, referring to FIG. 4 , a second connecting portion 426 may be provided on the outer surface of the first sidewall 421. The outer surface of the first sidewall 421 refers to the surface of the first sidewall 421 facing away from the inner cavity 425 of the first bracket 42. The second connecting portion 426 protrudes from the outer surface of the first sidewall 421 and is provided with a second through hole 427. This eliminates the need for the thickness of the first sidewall 421 to accommodate the second through hole 427, thereby achieving a thinner and lighter first bracket 42.

[0066] Please refer to Figure 5, which is a schematic diagram of the structure of the first wall panel 24 shown in Figure 3. The first wall panel 24 includes a third surface 241 and a fourth surface 242 disposed opposite each other, wherein the third surface 241 is the surface of the first wall panel 24 facing the circuit board 30. Limiting posts 243 are disposed on the third surface 241. The number of limiting posts 243 is equal to the number of second through holes 427. The number of limiting posts 243 can also be one, two, three, four, etc. This embodiment is described using the example of two limiting posts 243 and the example of second through holes 427 disposed on the first side wall 421 and the second side wall 422. One of the second through holes 427 is disposed on the end of the first side wall 421 near the third side wall 423, and the other second through hole 427 is disposed on the end of the second side wall 422 near the fourth side wall 424. This further improves the positioning accuracy of the camera module 40.

[0067] The limiting post 243 can be cylindrical or block-shaped. The embodiments of the present application are described using a cylindrical limiting post 243 as an example. The axis of the limiting post 243 is perpendicular to the third surface 241. In some embodiments, the limiting post 243 and the first wall panel 24 are an integral structural component. In other embodiments, the limiting post 243 and the first wall panel 24 can also be independent structural components. The limiting post 243 can be connected to the first wall panel 24 by bonding, welding, or other connection methods. The embodiments of the present application are described using an example in which the limiting post 243 and the first wall panel 24 are an integral structural component.

[0068] To ensure proper fit between the limiting post 243 and the second through hole 427, refer to Figure 6, which illustrates the structure of the circuit board 30 shown in Figure 3. A first through hole 33 is provided on the circuit board 30 opposite the limiting post 243. When the camera module 40 is assembled, the limiting post 243 passes through the first through hole 33 and engages with the second through hole 427 to limit the position of the camera module 40. This limiting action is achieved in two directions: the limiting post 243 defines the position of the camera module 40 in both the X-axis and Y-axis directions.

[0069] Please refer to Figures 5 and 6 together. The circuit board 30 and the midplane 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 the first threaded hole 244. Threaded connectors 50, such as screws or bolts, are disposed in the first and second threaded holes 244 to secure the circuit board 30 to the midplane. The first wall plate 24 shown in Figure 5 only illustrates one first threaded hole 244, and the circuit board 30 shown in Figure 6 also illustrates only one second threaded hole 34. The number of first threaded holes 244 can also be two, three, four, etc., and the number of first threaded holes 244 is the same as the number of second threaded holes 244.

[0070] As can be seen from the above, the circuit board 30 has a large number of openings, including holes for accommodating the limit posts 243 and holes for securing the circuit board 30. This significantly reduces the effective area available for mounting electronic components on the circuit board 30, and also affects the structural strength of the circuit board 30.

[0071] To address the above-mentioned issues, an embodiment of the present application further provides an electronic device 100, which aims to reduce the number of openings on a circuit board 30, thereby increasing the effective area of ​​the circuit board 30 and improving the structural strength of the circuit board 30. The main difference between the embodiment of the present application and the above-mentioned embodiment is that the structure of the limiting post 243 in this embodiment is different from the structure of the limiting post 243 in the above-mentioned embodiment.

[0072] For details, please refer to Figure 7, which is a schematic diagram of another structural connection between the camera module 40, circuit board 30, and midboard shown in Figure 2. The electronic device 100 includes a housing 20, a circuit board 30, a first structural member 40, and a connector 50. The housing 20 includes a first wall panel 24. The circuit board 30 is stacked with the first wall panel 24. The circuit board 30 has a first through hole 33. The first wall panel 24 and the circuit board 30 are arranged in a first direction, which is the Z-axis direction in Figure 7. The first structural member 40 is located on the side of the circuit board 30 facing away from the first wall panel 24. One of the first structural member 40 and the first wall panel 24 has a retaining post 243, and the other has a second through hole. At least a portion of the retaining post is located within the first through hole 33. The technical features of this embodiment of the present application are consistent with those described above. This embodiment and the following embodiments will also be described using the example of the first structural member 40 being a camera module 40, and the example of the retaining post being located in the first wall panel 24 and the second through hole being located in the first structural member 40.

[0073] It is worth noting that the following content is the difference between the embodiment of the present application and the above content. Please refer to Figure 8, which is a structural schematic diagram of the first wall panel 24 shown in Figure 7. The limiting column 243 has a third through hole 2431. Please refer to Figures 9 and 10. Figure 9 is a cross-sectional view at AA in Figure 7; Figure 10 is an exploded view of the first structural member 40, the circuit board 30 and the first wall panel 24 shown in Figure 9 at AA. 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. The connecting member 50 connects the shell 20 and the first structural member 40.

[0074] In this way, the limiting posts 243 can serve two purposes. First, the first structural member 40 is limited by the limiting posts 243. This limitation includes limiting the first structural member 40 in its own width, length, and thickness directions, that is, limiting the first structural member 40 in the X-axis, Y-axis, and Z-axis directions in Figure 8 . Furthermore, the first structural member 40 is fixed to the first wall panel 24 via the limiting posts 243. Second, the limiting posts 243 and one of the connectors 50 pass through the first through-holes 33 to limit the circuit board 30. This limitation includes limiting the circuit board 30 in its own length and width directions, that is, limiting the circuit board 30 in the X-axis and Y-axis directions in Figure 8 . Moreover, 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 shell 20 through the connecting member 50, the circuit board 30 located between the first structural member 40 and the first wall panel 24 is limited in its own thickness direction by means of the first structural member 40 and the first wall panel 24, that is, the X-axis direction in Figure 8.

[0075] In summary, the first structural member 40 is secured to the first wall panel 24 via the retaining posts 243, and the circuit board 30 is also secured to the first wall panel 24 via the retaining posts 243. Furthermore, the first structural member 40 and the circuit board 30 can share the first through-hole 33 for securing to the first wall panel 24. Consequently, the number of holes on the circuit board 30 used to secure itself and the number of holes used to secure the first structural member 40 are reduced, increasing the area on the circuit board 30 available for connecting other electronic components, thereby increasing the effective area of ​​the circuit board 30. This reduction in the number of holes on the circuit board 30 also helps improve the structural strength of the circuit board 30, thereby enhancing its reliability and stability.

[0076] Continuing with FIG9 , in some embodiments, at least a portion of the limiting post 243 is located within the first through-hole 33. This allows the circuit board 30 to be positioned by the cooperation between the first through-hole 33 and the limiting post 243. The inner wall of the first through-hole 33 can be smooth, and the outer circumference of the limiting post 243 is also smooth. The limiting post 243 is located within the first through-hole 33 to limit the position of the circuit board 30. Therefore, both the inner wall of the first through-hole 33 and the outer circumference of the limiting post 243 are smooth, making the positioning of the circuit board 30 more precise. Furthermore, the limiting post 243 is at least long enough to extend into the first through-hole 33, thereby increasing the mating area between the limiting post 243 and the connector 50. This provides a more stable connection between the limiting post and the connector 50, and a more stable connection between the first structural member 40, the circuit board 30, and the first wall panel 24.

[0077] Continuing with FIG9 , in some embodiments, at least a portion of the limiting post 243 is further positioned within the second through-hole 427. Thus, the first structural member 40 is positioned by the cooperation between the second through-hole 427 and the limiting post 243. The inner wall of the second through-hole 427 can be smooth, and the outer circumference of the limiting post 243 is also smooth. The limiting post 243 is positioned within the second through-hole 427 to limit the first structural member 40. Therefore, both the inner wall of the second through-hole 427 and the outer circumference of the limiting post 243 are smooth, making the positioning of the first structural member 40 more precise. Furthermore, the limiting post 243 is at least long enough to extend into the second through-hole 427, thereby increasing the mating area between the limiting post 243 and the connector 50. This provides a more stable connection between the limiting post and the connector 50, and a more stable connection between the first structural member 40, the circuit board 30, and the first wall plate 24.

[0078] The following describes in detail the connection method between the connector 50, 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 uses the connector 50 and the limiting column 243 being connected by threaded connection as an example.

[0079] Please refer to Figure 11, which is an enlarged view of point A in Figure 9. Specifically, the connector 50 includes a first connecting rod 51 and a fixing plate 52. The first connecting rod 51 can be rod-shaped, column-shaped, or block-shaped, while the fixing plate 52 is plate-shaped and connected to one end of the first connecting rod 51. In some embodiments, the first connecting rod 51 and the fixing plate 52 can be an integral structural member. In other embodiments, the first connecting rod 51 and the fixing plate 52 can be independent structural members, connected by welding, bonding, or other methods.

[0080] A portion of the first connecting rod 51 is located within the third through-hole 2431, and the fixing plate 52 is located on the side of the second through-hole 427 facing 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 post 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 in contact with the fixing plate 52 and there is no relative extrusion force between the second wall plate 428 and the fixing plate 52; second, the second wall plate 428 is in contact with the fixing plate 52 and there is a relative extrusion 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.

[0081] A portion of the connector 50 is connected to the limiting post 243, specifically, via a first connecting rod 51. The connection between the first connecting rod 51 and the limiting post 243 can be achieved through bonding, welding, or threading. In this embodiment, the threaded connection between the first connecting rod 51 and the limiting post 243 is used as an example. Specifically, threads are provided on the outer circumference of the first connecting rod 51, and threads that mate with the first connecting rod 51 are provided on the inner wall of the third through hole 2431, thereby achieving threaded engagement between the first connecting rod 51 and the third through hole 2431. In this manner, the first connecting rod 51 and the limiting post 243 are detachably connected, facilitating the disassembly of various components within the electronic device 100 during subsequent repairs. Furthermore, compared to other connection methods such as bonding and welding, the threaded connection between the first connecting rod 51 and the limiting post 243 simplifies assembly, facilitates accurate control of the installation between the connector 50 and the limiting post 243, and improves assembly efficiency of the electronic device 100.

[0082] The other portion 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 is in contact with the second wall plate 428.

[0083] In summary, the connector 50 secures the first structural member 40 to the first wall panel 24 via the fixing plate 52 and the first connecting rod 51. The connector 50 has a simple structure and facilitates assembly of the circuit board 30 and the first structural member 40, thereby improving assembly efficiency. Furthermore, the connector 50 provides a relatively stable connection between the first structural member 40, the circuit board 30, and the first wall panel 24. The connector 50 secures the first structural member 40 to the first wall panel 24, enabling full positioning of the first structural member 40, specifically limiting the first structural member 40 in its width, length, and thickness directions (i.e., the X-axis, Y-axis, and Z-axis directions in FIG. 11 ). The circuit board 30 can also be secured to the first wall panel 24 via the engagement of the limiting post 243 with the first structural member 40. Furthermore, the first structural member 40 and the circuit board 30 can share the first through-hole 33 for securing to the first wall panel 24. Therefore, the number of openings on the circuit board 30 used to secure the circuit board 30 and the number of openings used to secure 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. Reducing the number of openings on the circuit board 30 also helps to improve the structural strength of the circuit board 30 itself, thereby improving the reliability and stability of the circuit board 30.

[0084] Continuing with FIG. 11 , in some embodiments, the first structural member 40 further includes a fourth wall panel 429 surrounding the limiting post 243. The fourth wall panel 429 has a fourth wall panel 429 facing the circuit board 30, and the fourth wall panel 429 contacts the circuit board 30. In this way, the connector 50 secures the first structural member 40 to the first wall panel 24, securing the first structural member 40 in its thickness direction, i.e., the first direction. The first structural member 40 contacts the circuit board 30, and the circuit board 30 can be secured in the first direction with the aid of the first structural member 40. Furthermore, the limiting post 243 is located within the first through hole 33 of the circuit board 30, thereby limiting the circuit board 30 in its length and width directions, and securing the circuit board 30 in all directions.

[0085] Therefore, by providing only the first through-holes 33 on the circuit board 30, the first structural member 40 and the circuit board 30 can be secured. This reduces the number of openings on the circuit board 30 used to secure the circuit board 30 itself and the number of openings used to secure the first structural member 40. This increases the area of ​​the circuit board 30 available for connecting other electronic components, thereby increasing the effective area of ​​the circuit board 30. Reducing the number of openings on the circuit board 30 also helps improve the structural strength of the circuit board 30 itself, thereby enhancing the reliability and stability of the circuit board 30.

[0086] Please refer to Figure 12, which is another enlarged view of point A shown in Figure 9. In some embodiments, when the first structural member 40 is a metal structure, to ensure electrical connection between the first structural member 40 and the circuit board 30 and achieve grounding of the first structural member 40, the fourth wall plate 429 has a raised portion 430. The raised portion 430 is made of an elastic material and contacts the circuit board 30. The raised portion 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 via a connector 50. A locking force is exerted between the first structural member 40 and the connector 50 to secure the connection. When the fourth wall plate 429 contacts the circuit board 30, the fixing portion compresses the raised portion 430 through this locking force. The provision of the raised portion 430 prevents inadequate contact between the fourth wall plate 429 and the circuit board 30, thereby ensuring 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 the assembly of other structural members within the electronic device 100 and facilitating the assembly of other structural members within the electronic device 100.

[0087] Please refer to Figure 13, which is an enlarged view of point A shown in Figure 9. In some embodiments, a third structural member 70 is provided on the circuit board 30. The third structural member 70 can be a central processing unit (CPU), a graphics processing unit (GPU), a universal flash storage (UFS), an earpiece, 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 makes way for the installation space of 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.

[0088] Please refer to Figures 14, 15, and 16. Figure 14 is a schematic diagram of another structure of the camera module 40, circuit board 30, and midboard shown in Figure 2. Figure 15 is a cross-sectional view at point BB in Figure 14. Figure 16 is an enlarged view of point B in Figure 15. In some possible implementations, the electronic device 100 further includes a second structural member 60. The second structural member 60 is located on a side of the first structural member 40 facing away from the circuit board 30. In a first direction, the second structural member 60 contacts at least a portion of the first structural member 40. The second structural member 60 has a fourth through hole 61, the axis of which is parallel to the axis of the third through hole 2431. The second structural member 60 has a third wall panel 62 located between the first structural member 40 and the fixing plate 52. One side surface of the third wall panel 62 contacts the first structural member 40, while the other side surface of the first wall panel 24 contacts the fixing plate 52.

[0089] The second structural member 60 can be a circuit board 30 bracket 42. 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.

[0090] In this way, the connector 50 secures both the first structural member 40 and the second structural member 60 to the first wall panel 24 via the fixing plate 52 and the first connecting rod 51. The connector 50 has a simple structure, facilitating assembly of the circuit board 30, the first structural member 40, and the second structural member 60, thereby improving assembly efficiency of the circuit board 30, the first structural member 40, and the second structural member 60. Furthermore, the connection between the connector 50, the first structural member 40, the second structural member 60, the circuit board 30, and the first wall panel 24 is relatively stable.

[0091] In some embodiments, the first through hole 33 , the second through hole 427 and the third through hole 2431 are coaxial, so as to facilitate the assembly of the connector 50 with the first structural member 40 , the circuit board 30 and the first wall plate 24 .

[0092] In some other embodiments, the limiting post 243 can be provided on the first structural member 40, and the second through hole 427 can be provided on the first structural member 40. In this way, the flexibility of the setting position of the limiting post 243 and the second through hole 427 is improved, and the setting position of the limiting post 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 post can be provided on the first wall panel 24, and the circuit board 30 and the first structural member 40 can be installed in sequence, so as to facilitate 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 post can be provided on the first structural member 40, and the circuit board 30 and the housing 20 can be installed in sequence, so as to facilitate the assembly of the electronic device 100.

[0093] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
