Description

Technical Field

[0001] This application relates to the field of terminal equipment technology, and in particular to a bracket holder and electronic device. Background Technology

[0002] As electronic devices continue to become thinner and lighter, their internal space is shrinking, limiting the space available for electronic components. For example, some electronic components need to be fixed to circuit boards using brackets. Due to space constraints, the soldering area between the bracket and the circuit board is reduced, resulting in lower connection strength and affecting the reliability of the electronic components mounted on the circuit board. Summary of the Invention

[0003] This application provides a bracket holder and an electronic device to solve the problem that limited internal space in electronic devices reduces the welding area between the bracket holder and the circuit board, lowers the connection strength, and affects the reliability of electronic devices mounted on the circuit board.

[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0005] In a first aspect, a bracket holder is provided, which includes a cover plate and a base. The base includes a seat body and a protrusion. The protrusion is fixed to the bottom surface of the seat body and is used to extend into a notch opened on a circuit board. There are multiple bases, and the multiple bases are respectively engaged with the edge of the cover plate.

[0006] The bracket holder provided in the first aspect of this application has a protrusion on the bottom surface of the base so that the protrusion can be inserted into the notch on the circuit board. The surface of the protrusion and the inner wall of the notch form a contact surface between the base and the circuit board, which increases the contact area between the base and the circuit board, thereby increasing the welding area between the base and the circuit board to ensure the connection strength between the base and the circuit board.

[0007] In one possible implementation of the first aspect of this application, a plurality of protrusions are provided on the bottom surface of the base, and the plurality of protrusions are spaced apart. In this structure, the plurality of protrusions can further increase the contact area between the base and the circuit board, thereby helping to further improve the connection strength between the two and reducing the size of the base.

[0008] In one possible implementation of the first aspect of this application, the base includes a base plate and a snap-fit ​​portion. A protrusion is fixed to the bottom surface of the base plate, and the snap-fit ​​portion is disposed on the surface of the base plate away from the protrusion. A cover plate is stacked on top of the base plate and snaps into the snap-fit ​​portion. In this structure, the snap-fit ​​portion is used to fix the cover plate, and the base plate and the protrusion disposed on the base plate are used for connection with the circuit board, for example, by soldering, to ensure the connection strength between the base and the circuit board.

[0009] In one possible implementation of the first aspect of this application, the snap-fit ​​part includes an elastic wall plate with snap-fit ​​holes, and the edge of the cover plate snaps into the snap-fit ​​holes. In this structure, the elastic wall plate can undergo elastic deformation. When installing the cover plate, an external force can be applied to deform the elastic wall plate away from the cover plate, so that the edge of the cover plate aligns with the snap-fit ​​holes. Then, the external force is removed, and the elastic wall plate returns to its original position under the action of the elastic force, allowing the edge of the cover plate to insert into the snap-fit ​​holes, making installation more convenient.

[0010] In one possible implementation of the first aspect of this application, the elastic wall panel includes a guide region and a connecting region. The connecting region is fixed to the base plate, and a snap-fit ​​hole is formed in the connecting region. The guide region is located on the side of the connecting region away from the base plate and extends in a direction away from the base plate and away from the cover plate.

[0011] In this structure, during the installation of the cover plate, the cover plate is pressed down along the stacking direction of the cover plate and the base plate, causing the edge of the cover plate to abut against the guide area. Based on the inclined guide area, the cover plate exerts a component force on the guide area away from the cover plate, causing the elastic wall panel to elastically deform. Continuing to press the cover plate, when the edge of the cover plate separates from the guide area, i.e., when the edge of the cover plate aligns with the snap-fit ​​hole, the component force disappears, the elastic wall panel returns to its original position, and the edge of the cover plate inserts into the snap-fit ​​hole. This further reduces the difficulty of installing the cover plate.

[0012] In one possible implementation of the first aspect of this application, the snap-fit ​​hole penetrates the edge of the connecting area near the guide area. With this structure, when the cover plate is separated from the guide area, it aligns with the snap-fit ​​hole, saving the external force applied to the cover plate during installation and further reducing installation difficulty.

[0013] In one possible implementation of the first aspect of this application, the snap-fit ​​part includes a limiting plate and a connecting plate, the connecting plate being connected between the limiting plate and the base plate, and the edge of the cover plate being snapped between the limiting plate and the base plate. With this structure, one end of the cover plate can be inserted between the limiting plate and the base plate first, and then the other end of the cover plate can be pressed to snap into the aforementioned snap-fit ​​hole, thereby further reducing the difficulty of installation.

[0014] In one possible implementation of the first aspect of this application, the seat includes a limiting part disposed on the surface of the base plate away from the protrusion and along the width direction of the cover plate, on one side of the base plate. This structure can prevent the cover plate from moving along the width direction, thereby improving the limiting effect on the cover plate.

[0015] In one possible implementation of the first aspect of this application, the base includes two limiting parts, which are respectively disposed on both sides of the base plate along the width direction of the cover plate. With this structure, the limiting effect on the cover plate can be further enhanced by the two limiting parts.

[0016] In one possible implementation of the first aspect of this application, the limiting portion and the protrusion are spaced apart along the width direction of the cover plate. In this structure, the space between them forms a crack-resistant area, reducing the risk of tearing in the area between the limiting portion and the protrusion on the base plate.

[0017] In one possible implementation of the first aspect of this application, two bases are provided, located at both ends of the cover plate along its length. This structure ensures the cover plate is securely fixed while reducing costs.

[0018] In one possible implementation of the first aspect of this application, the two bases are staggered along the width direction of the cover plate. This structure facilitates avoidance of other components on the circuit board and contributes to the overall rationality of the layout.

[0019] In one possible implementation of the first aspect of this application, the cover plate includes a plate body and a snap-fit ​​plate. Multiple snap-fit ​​plates are provided and spaced apart along the edge of the plate body. Each snap-fit ​​plate snaps into a corresponding seat. In this structure, the snap-fit ​​plate snaps into the snap-fit ​​hole of the elastic arm or is inserted between the limiting plate and the base plate, thereby effectively limiting the cover plate.

[0020] In one possible implementation of the first aspect of this application, the snap-fit ​​plate includes a first plate and a second plate. The first plate extends towards the base plate and is fixed between the second plate and the plate body. The second plate is snapped into the base. In this structure, the first plate can be perpendicular to both the plate body and the first plate, i.e., the second plate is parallel to the plate body. When the second plate is inserted into the snap-fit ​​hole or between the limiting plate and the base plate, forces in other directions can be avoided, thereby reducing the risk of the second plate separating from the snap-fit ​​part and improving the overall structural reliability.

[0021] In one possible implementation of the first aspect of this application, the cover plate further includes an abutment plate extending towards the base plate and opposite to the seat. In this way, the abutment plate can abut against the base, thereby forming a length-direction limiting effect on the cover plate, further enhancing the limiting effect.

[0022] Secondly, an electronic device is provided, comprising a housing, a circuit board, electronic components, and a bracket holder. The circuit board is disposed within the housing and has mounting holes. The electronic components are disposed on the circuit board. The bracket holder is as described in any of the above technical solutions, with a base body disposed on the circuit board and a protrusion of the base extending into the mounting holes. A cover plate abuts against the side of the electronic components away from the circuit board.

[0023] The electronic device provided in the second aspect of this application, by including the bracket and card slot as described in any of the above technical solutions, is able to solve the same technical problem and achieve the same technical effect.

[0024] In one possible implementation of the second aspect of this application, the electronic device includes a board-to-board connector. Attached Figure Description

Detailed Implementation

[0049] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0050] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0051] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0052] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0053] This application provides an electronic device. Specifically, the electronic device can be a portable electronic device or other types of electronic devices. For example, the electronic device can be a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), monitor, camera, personal computer, laptop computer, wearable device, etc.

[0054] Furthermore, electronic devices can also be terminal devices with foldable screens, such as foldable screen phones. For ease of explanation, the following examples will use foldable screen phones as an example.

[0055] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 This is a structural diagram of an electronic device 01 provided in an embodiment of this application. Figure 2 This is a front view of an electronic device 01 provided in an embodiment of this application. The electronic device 01 may include a foldable screen 10 and a support device 20. The foldable screen 10 is supported and attached to the support device 20, and the support device 20 is capable of driving the foldable screen 10 to rotate between an unfolded state and a folded state. It is understood that... Figure 1 and Figure 2 Only some components of electronic device 01 are shown schematically; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 and Figure 2 The limitations of the structure shown.

[0056] For ease of description in the following embodiments, an XYZ coordinate system is established. When the electronic device 01 is in an unfolded or folded state, the width direction of the electronic device 01 is defined as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. It should be noted that this XYZ coordinate system can be flexibly transformed according to actual needs. The embodiments in this application only provide one possible example and should not be considered as a special limitation of this application.

[0057] The aforementioned foldable screen 10 is used to display images, videos, etc. The foldable screen 10 may include multiple first display areas 11 and at least one second display area 12, with the second display area 12 disposed between two adjacent first display areas 11. When the electronic device 01 is in a folded state, the second display area 12 of the foldable screen 10 is bent, and the multiple first display areas 11 are stacked. At least the second display area 12 of the foldable screen 10 uses a flexible screen. The first display areas 11 of the foldable screen 10 may use flexible screens, non-flexible screens, or a combination of both. Therefore, this application does not impose specific limitations in this regard.

[0058] Among them, the aforementioned foldable screen 10 can be an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MLED) display, a micro organic light-emitting diode (MOLED) display, a quantum dot light-emitting diode (QLED) display, a liquid crystal display (LCD), etc.

[0059] The aforementioned support device 20 is used to support the foldable screen 10. This support device 20 may include multiple housings 21 and at least one pivot mechanism 22, with the pivot mechanism 22 connecting two adjacent housings 21. The first display area 11 of the foldable screen 10 is supported and attached to the corresponding housing 21, and the second display area 12 of the foldable screen 10 is supported and attached to the corresponding pivot mechanism 22. Adjacent housings 21 are rotatably connected via a rotating mechanism, allowing the electronic device 01 to rotate between the unfolded and folded states. In the following embodiments, the following description uses the example of two housings 21, one pivot mechanism 22, two corresponding first display areas 11, and one second display area 12 of the foldable screen 10.

[0060] With electronic device 01 in the unfolded state, please continue reading. Figure 1 and Figure 2 , Figure 1 and Figure 2The diagram shows the structure of electronic device 01 in its unfolded state. In this state, the folding screen 10 can be fully unfolded, meaning that the two first display areas 11 and one second display area 12 of the folding screen 10 are on the same plane, ensuring the flatness of the folding screen 10. In this state, a large-screen display is achieved by electronic device 01, providing a better user experience. For example, when watching a movie, the large screen enhances the viewing experience.

[0061] When electronic device 01 is in a folded state, please refer to Figure 3 , Figure 3 This is a front view of an electronic device 01 in a folded state, as provided in an embodiment of this application. In this state, the two first display areas 11 of the folded screen 10 are opposite each other, the second display area 12 is bent, and the support device 20 protects the folded screen 10 from damage; that is, the folded screen 10 is positioned between the two housings 21 of the support device 20. In this state, the folded screen 10 is invisible to the user, preventing scratches or damage and thus providing effective protection for the folded screen 10. For example, when the phone is not needed, the electronic device 01 can be folded to avoid screen damage.

[0062] In some embodiments, please continue reading Figure 3 The electronic device 01 may also include an external screen 30 (also referred to as a secondary screen), which is located on the side of any of the housings 21 away from the folding screen 10. When the electronic device 01 is in the folded state, the external screen 30 can be used to display images, allowing users to operate it with one hand, thus making the use scenarios of the electronic device 01 more diverse. For example, when a user is riding public transportation, one hand needs to hold the handrail. At this time, the external screen 30 can be used to display images for one-handed operation, which helps to further improve the user experience.

[0063] Based on this, please refer to Figure 4 , Figure 4 This is an exploded view of an electronic device 01 provided in an embodiment of this application. The electronic device 01 also includes a circuit board 40 and electronic components 50. The circuit board 40 is used to realize electrical connections between the electronic components 50. The circuit board 40 can be fixed in the housing 21 by means of adhesive, threaded connection, welding, snap-fit, etc.

[0064] For example, each of the two housings 21 is provided with a circuit board 40, and the two circuit boards 40 can be electrically connected through an FPC board (Flexible Printed Circuit Board), so that different electronic devices 50 can be set on different circuit boards 40 according to actual needs, and can be electrically connected through the two circuit boards 40.

[0065] The aforementioned electronic device 50 is used to implement various functions of the electronic device 01. For example, the electronic device 50 can be a control chip (e.g., a system-on-chip, SOC), a graphics processing unit (GPU), universal flash storage (UFS), a camera module, a flash module, a battery, and capacitors, resistors, inductors, etc.

[0066] In some embodiments, the electronic device 50 can be fixed to the circuit board 40 by welding, bonding, or other methods, and is electrically connected to the circuit board 40. Alternatively, please refer to... Figure 5 , Figure 5 The diagram shows the structure of the connector 51 and the bracket holder 60 provided in the embodiment of this application. The electronic device 50 can also be electrically connected to the circuit board 40 through the connector 51. For example, the connector 51 can be a BTB connector (Board-to-board Connector). The connector 51 can include a plug and a socket. One of the plug and socket can be electrically connected to the electronic device 50 through the FPC board. The other of the plug and socket is soldered and fixed to the circuit board 40. The electronic device 50 and the circuit board 40 can be electrically connected by plugging and socketing each other.

[0067] To ensure the reliability of the interlocking of the plug and socket of the connector 51, the electronic device 01 may also include a bracket holder 60, which includes multiple bases 61 and a cover plate 62. The multiple bases 61 are soldered and fixed to the circuit board 40, and the multiple bases 61 are distributed at intervals around the connector 51.

[0068] For example, two bases 61 can be provided, with the two bases 61 distributed at both ends of the connector 51 along the length direction of the connector 51. The two ends of the cover plate 62 are respectively engaged with the two bases 61, and the cover plate 62 abuts against the surface of the connector 51 away from the circuit board 40, so that the connector 51 abuts between the cover plate 62 and the circuit board 40, thereby ensuring that the plug and socket of the connector 51 are stably connected, so as to ensure a stable electrical connection between the electronic device 50 and the circuit board 40.

[0069] It should be noted that the length and width directions of the cover plate 62 and connector 51 are parallel to the XY plane. For example, the length and width directions of the cover plate 62 and connector 51 can be parallel to the X-axis and Y-axis directions respectively, or they can intersect the X-axis and Y-axis directions. Therefore, this application does not impose any special limitations on this. In the following embodiments, the length direction of the cover plate 62 and connector 51 is taken as the Y-axis direction, and the width direction of the cover plate 62 is taken as the X-axis direction for illustration.

[0070] However, with the trend of electronic devices becoming increasingly thinner and lighter, the thickness of electronic devices is constantly decreasing, that is... Figure 4 As the thickness of the housing 21 decreases, the internal space of the housing 21 also decreases. This compresses the mounting space for the electronic components 50 within the housing 21, necessitating a continuous reduction in the size of some electronic components 50. For example, please refer to [further details omitted]. Figure 5 and in conjunction with reference Figure 6 , Figure 6 This is a bottom view of the bracket holder 60 provided in this embodiment. The size of the base 61 needs to be reduced. Reducing the size of the base 61 will cause the base 61 to face the surface of the circuit board 40 (e.g., Figure 6 The area of ​​the shaded part is reduced, which means the welding area between the two is reduced, resulting in a decrease in the welding strength between the base 61 and the circuit board 40, affecting the insertion reliability of the connector 51.

[0071] To resolve the above issues, please refer to [link / reference]. Figure 7 and Figure 8 , Figure 7 This is a structural diagram of a bracket holder 60 provided in an embodiment of this application. Figure 8 This is a cross-sectional view of an assembly structure of a bracket holder 60 and a circuit board 40 provided in an embodiment of this application. The bracket holder 60 can be applied to the aforementioned electronic device 01. The bracket holder 60 includes the aforementioned cover plate 62 and a plurality of bases 61, with the edges of the cover plate 62 engaging with the bases 61.

[0072] The base 61 includes a seat body 100 and a protrusion 200. The protrusion 200 is fixed to the bottom surface of the seat body 100. The circuit board 40 has a notch 41. The seat body 100 is disposed on the circuit board 40, that is, the bottom surface of the base 61 abuts against the circuit board 40, and the protrusion 200 extends into the notch 41.

[0073] The aforementioned protrusion 200 can be provided as a single part or as multiple parts. When multiple protrusions 200 are provided, they can be distributed at intervals on the bottom surface of the base 61. Correspondingly, multiple notches 41 can be provided on the circuit board 40 so that the multiple protrusions 200 can be inserted into the multiple notches 41.

[0074] In this way, inserting the protrusion 200 at the bottom of the base 100 into the notch 41 on the circuit board 40 increases the contact area between the base 61 and the circuit board 40, thereby increasing the welding area between the base 61 and the circuit board 40 and improving the connection strength between the base 61 and the circuit board 40. This ensures the clamping strength of the bracket holder 60 on the connector 51, ensuring the stable insertion of the connector 51, and thus helps to ensure a stable electrical connection between the electronic device 50 and the circuit board 40.

[0075] In some embodiments, the protrusion 200 can be a protrusion structure or a plate structure formed on the bottom surface of the base 100, for example, a protrusion structure formed on the bottom surface of the base 100 by a cutting process. Alternatively, the protrusion 200 can also be a plate structure formed at the edge of the bottom surface of the base 100 by a bending process. Or, the protrusion 200 can also be fixed to the bottom surface of the base 100 by welding, bonding or other methods.

[0076] For example, the protrusion 200 can extend along the Z-axis direction, and the notch 41 on the circuit board 40 also extends along the Z-axis direction, so that the protrusion 200 can be inserted into the notch 41. Furthermore, the length of the protrusion 200 along the Z-axis direction and the depth of the notch 41 along the Z-axis direction can be determined based on the thickness of the circuit board 40. For example, the depth of the notch 41 can be half the thickness of the circuit board 40. Alternatively, the notch 41 can also penetrate the circuit board 40 along the Z-axis direction, etc. Therefore, this application embodiment does not impose any special limitations in this regard.

[0077] Alternatively, please see Figure 9 , Figure 9 This is a cross-sectional view of another protrusion 200 provided in an embodiment of this application. The protrusion 200 can also extend along the Z-axis direction while tilting in any direction parallel to the XY plane, i.e., the protrusion 200 forms an angle with the Z-axis direction. Correspondingly, the notch 41 on the circuit board 40 can extend tilted in the same direction. In this way, when the protrusion 200 is inserted into the notch 41, the base 61 and the circuit board 40 can only separate from each other along the extending directions of the protrusion 200 and the notch 41. That is, the protrusion 200 and the notch 41 form a limiting structure between the base 61 and the circuit board 40, thereby further reducing the risk of separation between the base 61 and the circuit board 40 and improving the connection strength between the base 61 and the circuit board 40.

[0078] For example, when the protrusion 200 forms a plate structure, the protrusion 200 can extend obliquely as a whole, so that the protrusion 200 forms an angle with the Z-axis direction. For example, the above-described bending process can be used to form an angle between the protrusion 200 and the Z-axis direction. Alternatively, when the protrusion 200 forms a bump structure, one or more sidewalls of the protrusion 200 can extend obliquely, so that the sidewalls of the protrusion 200 form an angle with the Z-axis direction. For example, the above-described cutting process can be used to form an angle between the sidewalls of the protrusion 200 and the Z-axis direction.

[0079] In other examples, please refer to Figure 10 , Figure 10 This is a cross-sectional view of another protrusion 200 provided in an embodiment of this application. The protrusion 200 may further include a first portion 210 and a second portion 220. The first portion 210 is fixedly connected to the base 100 and can extend along the Z-axis direction. The second portion 220 is fixed to the end of the first portion 210 away from the base 100, and the extension direction of the second portion 220 can intersect the Z-axis direction. For example, the second portion 220 can extend along the Y-axis direction, meaning the cross-section of the protrusion 200 along the YZ plane can form an approximately "L"-shaped structure.

[0080] Correspondingly, the notch 41 includes a first region 41a and a second region 41b. The first region 41a extends along the Z-axis direction so that the protrusion 200 can extend into the first region 41a. The second region 41b communicates with the first region 41a so that the second portion 220 of the protrusion 200 can extend into the second region 41b. Furthermore, the second region 41b can extend in any direction parallel to the XY plane, for example, along the Y-axis direction.

[0081] Furthermore, along the extension direction of the second region 41b, i.e. the Y-axis direction, the width of the first region 41a is greater than the size of the protrusion 200, so that the protrusion 200 can extend into the first region 41a and the second part 220 of the protrusion 200 can be inserted into the second region 41b.

[0082] In addition, along the Y-axis direction, the second region 41b of the notch 41 is located on the side of the first region 41a away from the connector 51, so that the notch 41 will not occupy the area where the connector 51 contacts the circuit board 40, thereby saving the layout space of the circuit board 40.

[0083] When installing the base 61, the protrusion 200 of the base 61 can be inserted into the first region 41a of the notch 41 along the Z-axis direction, and then the protrusion 200 can be moved along the Y-axis direction so that the second part 220 of the protrusion 200 is inserted into the second region 41b. This forms a limiting structure between the second part 220 of the protrusion 200 and the second region 41b of the notch 41, thereby reducing the risk of separation between the base 61 and the circuit board 40 and improving the connection strength between them.

[0084] For some other possible examples, please refer to Figure 11 , Figure 11 This is a cross-sectional view of another protrusion 200 provided in an embodiment of this application. When the notch 41 penetrates the circuit board 40 along the Z-axis, the protrusion 200 of the base 61 can extend into the notch 41 along the Z-axis, and the end of the protrusion 200 away from the base 100 extends out of the notch 41 from the other side of the circuit board 40, i.e., the end of the protrusion 200 is located on the side of the circuit board 40 away from the base 100. Furthermore, by bending the end of the protrusion 200 using the aforementioned bending process, the end of the protrusion 200 abuts against the surface of the circuit board 40 away from the base 100, thereby effectively limiting the base 61 and improving the connection strength between the base 61 and the circuit board 40.

[0085] It is understood that the base 61 and the circuit board 40 are fixed together by welding, and the protrusion 200 of the base 61 and the notch 41 of the circuit board 40 can also be fixed together by welding. For example, solder paste can be used to fix the base 61 and the circuit board 40 together. Alternatively, the base 61 and the circuit board 40 can also be fixed together by adhesive or snap-fit. Therefore, this application embodiment does not impose any special limitations on this.

[0086] The above is a description of the specific structure of the protrusion 200 of the base 61. The following is a detailed description of the structure of the base body 100 of the base 61. Please refer to [link / reference]. Figure 12 and Figure 13 , Figure 12 This is a structural diagram of a base 61 provided in an embodiment of this application. Figure 13 An exploded view of a base 61 and a cover plate 62 provided in an embodiment of this application.

[0087] The base 100 may include a base plate 110 and a snap-fit ​​portion 120. The snap-fit ​​portion 120 is disposed on the surface of the base plate 110 away from the protrusion 200. The cover plate 62 is stacked with the base plate 110 along the Z-axis direction, and the cover plate 62 snaps into the snap-fit ​​portion 120. In this way, the cover plate 62 is snapped into the snap-fit ​​portion 120, which facilitates the installation and removal of the cover plate 62, thereby facilitating the disassembly or replacement of the connector 51 between the cover plate 62 and the circuit board 40, and reducing the difficulty of maintenance.

[0088] In some embodiments, please continue reading Figure 12 and Figure 13 The aforementioned snap-fit ​​portion 120 may include an elastic wall plate 121, on which a snap-fit ​​hole 121a is provided. The edge of the cover plate 62 can snap into the snap-fit ​​hole 121a. In this structure, the cover plate 62 can be pressed along the Z-axis direction, causing the elastic wall plate 121 to undergo elastic deformation, thereby allowing the cover plate 62 to approach the base plate 110 along the Z-axis direction and causing the edge of the cover plate 62 to insert into the snap-fit ​​hole 121a. At the same time, the elastic wall plate 121 returns to its original position under the action of elastic force, so as to achieve mutual snap-fit ​​between the cover plate 62 and the base 61.

[0089] To facilitate the interlocking of the cover plate 62 and the elastic wall plate 121, the elastic wall plate 121 may include a guide region 121b and a connecting region 121c. The connecting region 121c is fixed to the base plate 110, and the interlocking hole 121a is formed in the connecting region 121c. The guide region 121b is fixed to the side of the connecting region 121c away from the base plate 110. The guide region 121b extends away from the base plate 110 and away from the cover plate 62, that is, the guide region 121b forms an angle with the Z-axis direction.

[0090] For example, the elastic wall panel 121 can be formed by bending the edge area of ​​the base plate 110 through the bending process described above. Alternatively, the elastic wall panel 121 can also be disposed on the base plate 110 by cutting or welding. Therefore, the embodiments of this application do not impose any special limitations on this.

[0091] In this way, when the cover plate 62 is installed, the cover plate 62 moves towards the base plate 110 along the Z-axis direction. The edge of the cover plate 62 abuts against the guide area 121b, applying pressure to the guide area 121b. Since the guide area 121b extends at an angle, a component force away from the cover plate 62 can be generated on the guide area 121b, causing the elastic wall plate 121 to deform away from the cover plate 62, so that the cover plate 62 can continue to move towards the base plate 110 along the Z-axis direction. When the cover plate 62 moves to the connecting area 121c and is opposite to the snap-fit ​​hole 121a, that is, the cover plate 62 separates from the guide area 121b, the elastic wall plate 121 returns to its original position under the action of the elastic force, and the elastic wall plate 121 moves towards the cover plate 62, so that the edge of the cover plate 62 is inserted into the snap-fit ​​hole 121a, so that the cover plate 62 and the base 61 are snapped together.

[0092] For some possible examples, please refer to [link / reference needed]. Figure 12 and Figure 13 The aforementioned snap-fit ​​hole 121a can penetrate the edge of the connecting area 121c near the guide area 121b, so that after the edge of the cover plate 62 is separated from the guide area 121b, it can be opposite to the snap-fit ​​hole 121a, so that the elastic wall plate 121 is reset under the action of elastic force, and the cover plate 62 and the elastic wall plate 121 are snapped together, which helps to shorten the relative movement time of the cover plate 62 and the elastic wall plate 121, thereby helping to reduce the installation difficulty.

[0093] Furthermore, the aforementioned snap-fit ​​hole 121a can also extend to the guide region 121b, or the snap-fit ​​hole 121a can also be formed on the guide region 121b, thereby further shortening the relative movement time between the cover plate 62 and the elastic wall plate 121. Therefore, the embodiments of this application do not impose any special limitations in this regard.

[0094] In other embodiments, please refer to Figure 14 , Figure 14 This is a partial structural diagram of another base 61 and cover plate 62 provided in an embodiment of this application. The snap-fit ​​portion 120 of the base 61 may further include a limiting plate 122 and a connecting plate 123. The connecting plate 123 is connected between the limiting plate 122 and the base plate 110, and the edge of the cover plate 62 is snapped between the limiting plate 122 and the base plate 110. Exemplarily, the limiting plate 122 and the connecting plate 123 can both be formed by bending the sheet material twice through a bending process to form the base plate 110, the connecting plate 123, and the limiting plate 122 connected in sequence.

[0095] In other possible embodiments, the aforementioned snap-fit ​​portion 120 can also have other structures. For example, the snap-fit ​​portion 120 includes two elastic arms that can be distributed along the X-axis direction. The end of the cover plate 62 can be snapped between the two elastic arms, thereby achieving mutual snap-fit ​​between the cover plate 62 and the base 61. In this structure, by pressing the end of the cover plate 62, the end of the cover plate 62 can be clamped between the two elastic arms, which helps to further reduce the difficulty of installation.

[0096] Based on the above embodiments, please refer to Figure 15 and Figure 16 , Figure 15 This is a structural diagram of another base 61 provided in an embodiment of this application. Figure 16 This is a structural diagram of another type of base 61 provided in an embodiment of this application. The bracket holder base 61 may further include a limiting portion 124, which is disposed on the surface of the base plate 110 away from the protrusion 200 and along the X-axis direction, on one side of the base plate 110. In this way, the limiting portion 124 can limit the cover plate 62 along the X-axis direction, thereby improving the reliability of the overall structure.

[0097] Furthermore, the base 100 may include two limiting parts 124, which are distributed on both sides of the base plate 110 along the X-axis direction, thereby further improving the limiting effect on the cover plate 62.

[0098] Furthermore, the angle formed between the limiting part 124 and the base plate 110 can be a right angle, that is, the limiting part 124 and the base plate 110 are perpendicular to each other. Alternatively, the angle formed between the limiting part 124 and the base plate 110 can be an acute angle, that is, the angle between the two is less than 90°, so that the limiting part 124 can prevent the cover plate 62 from moving along the Z-axis direction. Thus, while the limiting part 124 limits the cover plate 62 in the X-axis direction, it can also limit the cover plate 62 in the Z-axis direction, which is beneficial to further improve the limiting effect on the cover plate 62.

[0099] In some embodiments, please continue reading Figure 17 and Figure 18 , Figure 17 This is another structural view of a different base 61 provided in an embodiment of this application. Figure 18 This is another structural view of a base 61 provided in an embodiment of this application. Along the X-axis, the limiting portion 124 and the protrusion 200 are spaced apart to form a crack-prevention area between them, such as... Figure 17 and Figure 18 Area A is shown in the diagram.

[0100] In this way, since the protrusion 200 and the limiting part 124 of the seat body 100 are both formed by the above-mentioned bending process, since the protrusion 200 and the limiting part 124 are bent towards both sides of the base plate 110 along the Z-axis direction, in order to avoid tearing of the area between the protrusion 200 and the limiting part 124 on the base plate 110 during bending, the protrusion 200 and the limiting part 124 can be spaced apart to form the above-mentioned anti-crack area. This can increase the size of the base plate 110 along the X-axis direction between the protrusion 200 and the limiting part 124, thereby improving the tensile strength of the base plate 110 and thus reducing the risk of the base plate 110 being torn during bending.

[0101] Based on this, please refer to Figure 19 and Figure 20 , Figure 19 This is a structural diagram of another bracket holder 60 provided in an embodiment of this application. Figure 20 This is an exploded view of another bracket holder 60 provided in an embodiment of this application. The base 61 with the snap-fit ​​portion 120 formed by the elastic wall plate 121 can be referred to as the first base 61a, and the base 61 with the snap-fit ​​portion 120 formed by the limiting plate 122 and the connecting plate 123 can be referred to as the second base 61b. To facilitate the installation of the cover plate 62, one of the two bases 61 provided at both ends of the cover plate 62 can be the first base 61a, and the other can be the second base 61b.

[0102] When installing the cover plate 62, firstly insert the first end of the cover plate 62 between the limiting plate 122 and the base plate 110 of the second base 61b. Then, press the second end of the cover plate 62 so that the second end of the cover plate 62 abuts against the elastic wall plate 121 of the first base 61a. Continue pressing the second end of the cover plate 62. Under the action of the guide area 121b of the elastic wall plate 121, the second end of the cover plate 62 pushes the elastic wall plate 121 to deform away from the cover plate 62. The second end of the cover plate 62 continues to move towards the base plate 110 of the first base 61a. When the second end of the cover plate 62 is opposite to the snap-fit ​​hole 121a, the elastic wall plate 121 resets under the action of elastic force, so that the second end of the cover plate 62 is inserted into the snap-fit ​​hole 121a, thereby completing the installation of the cover plate 62. In this way, when installing the cover plate 62, there is no need to bend or squeeze the cover plate 62. Both ends of the cover plate 62 can be snapped into the first base 61a and the second base 61b respectively, which helps to reduce the difficulty of installation.

[0103] Alternatively, the two bases 61 described above can adopt the exact same structure. For example, the snap-fit ​​portion 120 of the base 61 is composed of two elastic arms. When installing the cover plate 62, press the first end and the second end of the cover plate 62 respectively so that the first end and the second end of the cover plate 62 snap between the corresponding two elastic arms.

[0104] It is understood that the snap-fit ​​portion 120 of the first base 61a and the second base 61b can also be flexibly selected with appropriate structure based on actual design and usage requirements. Therefore, this application does not impose any special limitations on this.

[0105] Based on this, please continue to refer to Figure 19 and Figure 20 The cover plate 62 may include a board body 300 and a snap-fit ​​plate 400. The snap-fit ​​plate 400 is fixed to the board body 300. Multiple snap-fit ​​plates 400 may be provided and are distributed at intervals along the edge of the board body 300. The snap-fit ​​plate 400 snaps into the corresponding base 61. In this way, by snapping the snap-fit ​​plate 400 of the cover plate 62 into the base 61, the board body 300 of the cover plate 62 can abut against the surface of the connector 51 away from the circuit board 40. This allows the cover plate 62 to be fixed to the circuit board 40 by the base 61, and the connector 51 abuts between the board body 300 of the cover plate 62 and the circuit board 40. This reduces the risk of the plug and socket of the connector 51 separating along the Z-axis, thereby improving the reliability of the overall structure.

[0106] In some embodiments, the snap-fit ​​plate 400 may include a first plate 410 and a second plate 420. The first plate 410 extends toward the base plate 110 and is fixed between the second plate 420 and the plate body 300. The second plate 420 is snapped into the snap-fit ​​hole 121a, thereby realizing the snap-fit ​​plate 400 and the base 61 snapping together.

[0107] For example, the first plate 410 can be perpendicular to the plate body 300, and the second plate 420 can be perpendicular to the first plate 410, that is, the second plate 420 can be parallel to the plate body 300, thereby facilitating the insertion of the second plate 420 into the snap-fit ​​hole 121a of the first base 61a, or between the base 61 of the second base 61b and the limiting plate 122. Furthermore, since the second plate 420 is parallel to the plate body 300, the insertion of the second plate 420 into the snap-fit ​​hole 121a can limit the plate body 300 along the Z-axis direction, thereby reducing the risk of the plate body 300 moving away from the base 61.

[0108] It is understood that in other possible examples, the included angles formed between the first plate 410 and the plate body 300, and between the second plate 420 and the first plate 410, may also be acute or obtuse. Therefore, this application does not impose any special limitations on this.

[0109] In addition, two snap-fit ​​plates 400 can be provided, namely a first snap-fit ​​plate 400a and a second snap-fit ​​plate 400b, and the first snap-fit ​​plate 400a and the second snap-fit ​​plate 400b are respectively provided at both ends of the plate body 300 along the length direction, that is, the first snap-fit ​​plate 400a is snapped with the first base 61a, and the second snap-fit ​​plate 400b is snapped with the second base 61b.

[0110] Therefore, the second plate 420 of the first snap-fit ​​plate 400a is inserted into the snap-fit ​​hole 121a of the first base 61a, and the second plate 420 of the second snap-fit ​​plate 400b is inserted between the bottom plate 110 and the limiting plate 122 of the second base 61b, thereby achieving the limiting of the cover plate 62 along the Z-axis direction. The second plate 420 of the first snap-fit ​​plate 400a is located between the two limiting parts 124 of the first base 61a, and the second plate 420 of the second snap-fit ​​plate 400b is located between the two limiting parts 124 of the second base 61b, thereby achieving the limiting of the cover plate 62 along the X-axis direction.

[0111] Based on this, please refer to Figure 21 and Figure 22 , Figure 21 This is a structural diagram of another bracket holder 60 provided in an embodiment of this application. Figure 22 This is an exploded view of another bracket holder 60 provided in an embodiment of this application. The cover plate 62 of the bracket holder 60 may further include an abutment plate 500, which extends towards the base plate 110 and is opposite to the seat body 100. For example, the abutment plate 500 may be disposed at the same end of the plate body 300 as the first snap-fit ​​plate 400a. When the first snap-fit ​​plate 400a is snapped into the snap-fit ​​hole 121a, the abutment plate 500 is opposite to the elastic wall plate 121 of the first base 61a. Furthermore, the first plate body 410 of the second snap-fit ​​plate 400b may be opposite to the side wall of the limiting plate 122 of the second base 61b. That is, when the abutment plate 500 abuts against the connection area 121c of the elastic arm plate, and the first plate body 410 of the second snap-fit ​​plate 400b abuts against the side wall of the limiting plate 122 of the second base 61b, the cover plate 62 can be limited along the Y-axis direction.

[0112] In this way, the cover plate 62 is limited along the X-axis, Y-axis and Z-axis directions to ensure that the cover plate 62 will not move in any direction, thereby improving the fixing effect of the cover plate 62 on the connector 51, which is conducive to further improving the connection stability of the connector 51 and the stability of the electrical connection between the electronic device 50 and the circuit board 40.

[0113] Based on this, please refer to Figure 23 , Figure 23This is a structural diagram of another bracket holder 60 provided in an embodiment of this application. The plate body 300 of the bracket holder 60 has a center line A parallel to the X-axis direction. The first latching plate 400a and the second latching plate 400b can be symmetrically distributed at both ends of the plate body 300 along the center line A. That is, the first base 61a and the second base 61b are also symmetrically distributed on both sides of the center line A, which helps to reduce the space occupied by the bracket holder 60 on the circuit board 40, so as to ensure that it does not affect the setting of other electronic devices 50.

[0114] In some possible embodiments, the first snap-fit ​​plate 400a and the second snap-fit ​​plate 400b can also be staggered along the X-axis direction, that is, the first base 61a and the second base 61b are also staggered along the X-axis direction. In this way, the placement of the first base 61a and the second base 61b can be more flexible, so as to avoid other electronic devices 50 that are close to the connector 51, which helps to improve the rationality of the layout.

[0115] It is understood that the staggered distribution of the first latching plate 400a and the second latching plate 400b along the X-axis means that the first latching plate 400a and the second latching plate 400b are not in the same position along the X-axis. That is, the first latching plate 400a and the second latching plate 400b are distributed sequentially along the X-axis, and they may partially overlap, or they may be distributed at intervals so that the line connecting them intersects the Y-axis (i.e., they are not parallel). Similarly, the relative positions of the first base 61a and the second base 61b are correspondingly set, therefore, they will not be described again.

[0116] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0117] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
