[0003] In related technologies, the circuit board is fixed to one side of the backplate by multiple screws. This fixing method requires not only machining threaded holes or riveting threaded posts at the corresponding mounting locations, but also repeatedly tightening each screw during board assembly. This results in low assembly efficiency for the circuit board. Summary of the Invention

The resilient buckle includes a connector, an elastic member, and a stop member connected in sequence. The connector is connected to the circuit board. The stop member is configured to pass through the first through hole when the elastic member is in a compressed state, and to engage with the bracket to stop when the elastic member rebounds.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0039] Before introducing the flexible snap-fit, circuit board, and electronic device provided by the embodiments of this application, the relevant technologies of this application will be introduced first.
[0040] In related technologies, a circuit board is included, which is fixed to a bracket of an electronic device. The circuit board is fixed to the bracket by multiple screws. This fixing method not only requires machining threaded holes in the bracket or riveting post with threaded holes, but also requires tightening each screw multiple times during circuit board assembly. As a result, the assembly efficiency of the circuit board is low.
[0041] In addition, if the screws are tightened too much, the threads that mate with the screws on the bracket may be damaged. Furthermore, excessive tightening force may cause dents or even cracks at the point where the circuit board meets the screw head, thus affecting the lifespan of the circuit board.
[0042] Based on this, this application provides a circuit board and electronic device that connects the circuit board to the bracket through elastic clips. This not only avoids many problems associated with screw connections, but also allows for a direct assessment of whether the circuit board and bracket are properly assembled, thereby improving the yield rate of the circuit board.
[0043] Meanwhile, the circuit board provided in the embodiments of this application can be directly mounted on the back panel of an electronic device, and correspondingly, the bracket is part of the back panel of the electronic device. The circuit board can also be fixed to the back panel of the electronic device via an adapter, that is, a bracket is provided between the back panel of the electronic device and the circuit board, with one side of the bracket used to fix the circuit board and the other side connected to the back panel.
[0044] The following is a detailed description of an elastic clip, board, and electronic device provided in the embodiments of this application.
[0045] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of board 2 provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of the elastic buckle 1 provided in the embodiments of this application. Figure 3 This is a partially enlarged view of the circuit board and the elastic snap-fit connection provided in an embodiment of this application. An embodiment of this application provides a circuit board 2, applied to an electronic device. The circuit board 2 includes a circuit board 22 and an elastic snap-fit 1. The circuit board 22 is configured to be connected to a bracket 21 of the electronic device. The bracket 21 is provided with a first through hole 212. The elastic snap-fit 1 includes a connector 11, an elastic element 12, and a stop 13 connected in sequence. The connector 11 is connected to the circuit board 22. The stop 13 is configured to pass through the first through hole 212 when the elastic element 12 is in a compressed state, and to engage with the bracket 21 to stop the elastic element 12 when it rebounds. Figure 4 As shown, Figure 4 A partial structural diagram showing the connection between the board 2 and the bracket 21 provided in an embodiment of this application.
[0046] Specifically, when the elastic member 12 rebounds, the stop member 13 and the bracket 21 engage in a blocking engagement along a first direction. The first direction is perpendicular to the circuit board 22 and parallel to the direction in which the stop member 13 passes through the first through hole 212.
[0047] It is understood that the bracket 21 can be the back panel of an electronic device, or it can be an adapter added between the back panel and the circuit board. The electronic device can be a smart interactive flat panel, a display device, etc.
[0048] It is understood that the axis of the first through hole 212 is perpendicular to the plane where the circuit board 22 is located, and the stop 13 can pass through the first through hole 212 along the axis of the first through hole 212.
[0049] Alternatively, connector 11 can be located on the side of circuit board 22 closer to bracket 21, or it can be located on the side of circuit board 22 away from bracket 21, such as... Figure 2 As shown.
[0050] For example, the elastic element 12 can be a metal spring, such as a "U-shaped" metal spring, or an S-shaped metal spring. The elastic element 12 can also be a coil spring, with its two axial ends connected to the connecting member 11 and the stop member 13, respectively.
[0051] When removing the circuit board 22 from the bracket 21, the elastic member 12 is compressed so that the stop member 13 is opposite to the first through hole 212. Then, the circuit board 22 is moved in the opposite direction of the through hole so that the circuit board 22 and the bracket 21 are moved away from each other until the stop member 13 is removed from the first through hole 212, thereby realizing the disassembly between the circuit board 22 and the bracket 21.
[0052] In this embodiment, by setting the elastic buckle 1, the elastic element 12 can be compressed so that the stop 13 passes through the first through hole 212. Then, the elastic element 12 rebounds so that the stop 13 engages with the bracket to complete the assembly of the board 2. In this way, the assembly process of the board 2 can be simplified, eliminating the need for repeated tightening of screws, and the operation is simple and direct, thereby improving the assembly efficiency of the board 2.
[0053] In addition, compared with the use of screws to fasten the board 2, the board 2 provided in the embodiments of this application can also avoid the situation where the screw threads of the board 2 are damaged or the connection is unstable due to excessive or insufficient tightening force of the screws. In this way, the reliability of the connection between the board 2 and the bracket 21 can be improved.
[0054] Please see Figure 2 In some embodiments, the elastic element 12 is a "U-shaped" elastic arm, which is connected to the connector 11 and the stop 13 respectively.
[0055] For example, the elastic member 12, the connector 11, and the stop member 13 can be integrally formed.
[0056] In this embodiment, by using a "U-shaped" elastic arm as the elastic element 12, on the one hand, the elastic element 12 can bear the compressive force evenly when subjected to force, thereby providing good elastic recovery performance and maintaining stable elastic performance; on the other hand, the structure of the elastic element 12 is simple and occupies less space, making it suitable for space-constrained applications.
[0057] In some embodiments, the "U-shaped" elastic arm includes a first arm 121, a bending portion 122, and a second arm 123 connected in sequence. The end of the first arm 121 is connected to a connector 11. A stop 13 is connected to the side of the second arm 123 opposite to the first arm 121. The distance between the first arm 121 and the second arm 123 gradually decreases in the direction close to the bending portion 122.
[0058] It is understood that the first arm 121 and the second arm 123 are arranged opposite to each other. The first arm 121 and the bent part 122, as well as the second arm 123 and the bent part 122, are smoothly connected to reduce stress concentration at the corners.
[0059] In this embodiment, by gradually reducing the distance between the first arm 121 and the second arm 123, the smaller end of the elastic member 12 can provide guidance for the engagement between the elastic member 12 and the first through hole 212, thereby improving the smoothness of the elastic member 12 passing through the first through hole 212, thus improving assembly efficiency and ease of operation.
[0060] Please see Figure 2 In some embodiments, the elastic member 12 has a first through hole 124 on the side near the stop member 13. A portion of the periphery of the stop member 13 is connected to the wall of the first through hole 124, and another portion of the periphery is configured to engage with the bracket 21. This ensures that, except for the periphery that abuts against the bracket 21, the remaining periphery of the stop member 13 is connected to the elastic member 12, thereby improving the reliability of the connection between the stop member 13 and the elastic member 12 and preventing damage to the connection between the stop member 13 and the elastic member 12 due to contact between the stop member 13 and the bracket 21. This improves the structural reliability of the elastic buckle 1.
[0061] The first through hole 124 is provided in the second arm 123.
[0062] Please see Figure 2 In some embodiments, the end of the second arm 123 away from the bend 122 is a contact portion 125. The contact portion 125 is configured to at least partially abut against the bracket 21 to prevent the stop 13 from disengaging from the stop engagement with the bracket 21.
[0063] For example, the contact portion 125 is parallel to the surface of the bracket 21 that contacts it, so as to increase the contact area between the contact portion 125 and the bracket 21, thereby improving the stress state of the contact portion 125.
[0064] In this embodiment, by abutting the contact portion 125 against the bracket 21, the area of the contact surface between the elastic buckle 1 and the bracket 21 can be increased to improve the stress state of the elastic buckle 1; and, under the combined effect of the connection between the connector 11 and the circuit board 22 and the contact portion 125 against the bracket 21, the connection stability between the circuit board 22 and the bracket 21 can be improved.
[0065] Please see Figure 5 , Figure 5 This is a schematic diagram of the elastic snap fastener 1 from another perspective, provided by an embodiment of this application. In some embodiments, the elastic snap fastener 1 further includes a connecting pin 14. One end of the connecting pin 14 is connected to the connector 11, and the other end is configured to be inserted into the circuit board 22.
[0066] For example, when the connector 11 is located on the side of the circuit board 22 close to the bracket 21, the connecting foot 14 can be interference-fitted with the circuit board 22 to ensure the reliability of the connection between the elastic buckle 1 and the circuit board 22; in addition, when the connector 11 is located on the side of the circuit board 22 away from the bracket 21, the connecting foot 14 is inserted into the circuit board 22 from the surface of the connector 11. At this time, the connector 11 limits the circuit board 22. Correspondingly, the connecting foot 14 can be interference-fitted with the circuit board 22, or it can be clearance-fitted or transition-fitted.
[0067] In this embodiment, by providing the connecting foot 14, not only can the ease of operation of the connection between the elastic buckle 1 and the circuit board 22 be improved, but the elastic buckle 1 can also be made simple in structure and easy to manufacture, thereby reducing production costs.
[0068] Please see Figure 5 In some embodiments, there are multiple connecting pins 14. The multiple connecting pins 14 are connected to the edge of the connector 11.
[0069] Specifically, there are four connecting feet 14, with each pair of connecting feet 14 forming a group. Along the arrangement direction of the connector 11 and the elastic member 12, the two groups of connecting feet 14 are located on both sides of the connector 11.
[0070] In this embodiment, by providing multiple connecting pins 14, the reliability of the connection between the elastic buckle 1 and the circuit board 22 can be improved.
[0071] In some embodiments, the elastic buckle 1 is a one-piece molded part. In this way, on the one hand, the elastic buckle 1 has good manufacturability, thereby improving its manufacturing efficiency; on the other hand, it can improve its strength and durability, and can also mean that it has good elastic recovery performance.
[0072] Specifically, the elastic buckle 1 is formed by repeatedly bending a metal sheet. For example, the various parts of the elastic buckle 1 are first punched out on the base material. Then, the connecting leg 14 is bent relative to the connector 11 so that the connecting leg 14 is perpendicular to the connector 11; at the same time, the part of the forming elastic element 12 is bent multiple times to form a "U-shaped" elastic arm structure. The stop 13 can be formed directly during punching.
[0073] Please see Figures 6 to 8 , Figure 6 This is a schematic diagram of the structure of the board 2 provided in the embodiments of this application, installed in an electronic device. Figure 7 yes Figure 6 Enlarged view of point A in the middle. Figure 8 yes Figure 7A cross-sectional view of BB. Accordingly, embodiments of this application also provide an electronic device. The electronic device includes a bracket 21 and the aforementioned board 2. The bracket 21 is provided with a first through hole 212. The bracket 21 is at least a part of the back panel of the electronic device, or the bracket 21 is disposed on the back panel of the electronic device. A circuit board 22 is connected to one side of the bracket 21. One end of the elastic member 12 and the stop member 13 pass through the first through hole 212, and the end of the stop member 13 away from the elastic member 12 is engaged with the bracket 21 in a first direction for blocking.
[0074] The electronic devices can be computer hosts, display devices, etc. Specifically, display devices include, but are not limited to, smart interactive flat panels, smart interactive blackboards, and smart interactive whiteboards.
[0075] In this embodiment, by employing the board 2 provided in some embodiments of this application, the board 2 can be detachably fixed inside the electronic device. The board can be a motherboard or power board of a display device, etc. Thus, compared to a screw-based connection method, assembling the board 2 using the elastic clip 1 not only improves the ease of assembly and efficiency of the electronic device but also enhances its structural reliability, preventing damage to the screw threads or poor internal fixation due to excessive or insufficient screw tightening force.
[0076] Please see Figure 7 and Figure 8 In some embodiments, the circuit board 22 is provided with a second through hole 221. The bracket 21 includes a first body 211 and a support base 2141 protruding upward from the first body 211 (i.e., along a first direction); the first through hole 212 is provided on the top surface of the support base 2141, one side of the top surface of the support base 2141 contacts the circuit board 22 to support the circuit board 22, and the other side extends upward to form a through portion 213. One end of the through portion 213 away from the first body 211 passes through the second through hole 221. A limiting groove 2134 is provided on one side of the through portion 213. The stop member 13 is located in the limiting groove 2134 and is engaged with the groove wall of the limiting groove 2134 away from the first body 211.
[0077] Specifically, the support base 2141 protrudes outward from the surface of the first body 211 along a first direction.
[0078] It can be understood that the axis of the second through hole 221 is perpendicular to the plane where the circuit board 22 is located; the through part 213 can pass through the second through hole 221 along the axis of the second through hole 221.
[0079] In this embodiment, the part where the bracket 21 and the elastic buckle 1 stop and cooperate is set on the side of the circuit board 22 away from the bracket 21, so that after the assembly is completed, the relevant personnel can directly visually inspect and judge whether the assembly between the elastic buckle 1 and the bracket 21 is in place, so as to ensure the convenience of assembly.
[0080] Furthermore, by setting the support base 2141 to contact the circuit board 22, the circuit board 22 can be supported by the support base 2141, so that the circuit board 22 and the bracket 21 are spaced apart to facilitate airflow between them. In this way, the heat generated by the circuit board 22 can be dissipated through the gap between it and the bracket 21, thereby improving the heat dissipation efficiency of the circuit board 22 and enhancing the operational reliability of the board 2.
[0081] Please see Figure 8 In some embodiments, the side of the limiting groove 2134 near the first body 211 communicates with the first through hole 212, and the wall of the first through hole 212 near the limiting groove 2134 smoothly transitions to the inner wall of the limiting groove 2134. This reduces the number of corners on the bracket 21 around the first through hole 212, thereby improving stress concentration and enhancing the stress state of the bracket 21.
[0082] Specifically, along the direction away from the connecting part, the side of the contact part 125 opposite to the connecting member 11 abuts against the through part 213.
[0083] Please see Figures 8 to 12 , Figure 9 This is a schematic diagram of the structure of the bracket 21 provided in an embodiment of this application. Figure 10 yes Figure 9 Enlarged view at point C in the middle. Figure 11 This is a schematic diagram of the structure of the circuit board 22 provided in an embodiment of this application. Figure 12 yes Figure 11 Enlarged view at point D. In some embodiments, the bracket 21 is provided with a first positioning structure 214, such as... Figure 10 As shown. Circuit board 22 is provided with a second positioning structure 222, as follows. Figure 12 As shown. The first positioning structure 214 and the second positioning structure 222 are inserted along a first direction, wherein the first direction is perpendicular to the plane where the circuit board 22 is located, as shown. Figure 8 As shown.
[0084] It can be understood that in the first positioning structure 214 and the second positioning structure 222, one is a groove or hole structure, and the other is a male connector that mates with it.
[0085] Specifically, the first positioning structure 214 is a column, and the second positioning structure 222 is a hole. One side wall of the hole is connected to one side wall of the second through hole 221.
[0086] Specifically, along the thickness direction of the circuit board 22, the second positioning structure 222 is disposed opposite to the connector 11. Correspondingly, the first positioning structure 214 is disposed adjacent to the first through hole 212.
[0087] Optionally, the first positioning structure 214 is disposed on the top surface of the support 2141 and in contact with the circuit board 22.
[0088] In this embodiment, by setting the first positioning structure 214 and the second positioning structure to be inserted, not only can the reliability of the connection between the circuit board 22 and the bracket 21 be improved, but also the positioning of the circuit board 22 and the bracket 21 can be improved based on the insertion, so as to avoid one of them moving relative to the other in any direction perpendicular to the insertion direction, thereby improving the structural reliability of the board 2.
[0089] Please see Figure 6 and Figure 13 , Figure 13 yes Figure 6 In the enlarged view at point E, in some embodiments, the bracket 21 further includes a third positioning structure 215 connected to the first body 211. The third positioning structure 215 and the elastic buckle 1 can be located on opposite sides of the circuit board 22 in the length or width direction, respectively. The third positioning structure 215 is provided with an insertion hole 2151. A plug-in portion 224 is formed on the circuit board 22, at least a portion of which is inserted into the insertion hole 2151 to restrict movement of the circuit board 22 along the first direction.
[0090] The first direction is perpendicular to the plane where the circuit board 22 is located.
[0091] It can be understood that the circuit board has a rectangular plate-like structure, and the third positioning structure 215 and the elastic buckle 1 can be located on both sides of the length direction of the circuit board 22, or on both sides of the width direction of the circuit board 22. Correspondingly, the insertion hole 2151 is provided on the side of the third positioning structure 215 facing the elastic buckle 1.
[0092] Specifically, the insertion part 224 and the socket 2151 are fitted with a clearance. The fitting clearance between the part of the circuit board 22 that inserts into the socket 2151 and the socket 2151 is 0.1-0.3mm.
[0093] It is understood that the remaining edges of the circuit board 22 near the third positioning structure 215 are engaged with the third positioning structure 215.
[0094] Specifically, during assembly, first connect the connector 11 of the elastic buckle 1 to the circuit board 22. Then, insert the plug 224 obliquely into the socket 2151. Here, oblique insertion means that the circuit board 22 and the bracket 21 form an acute angle, and the elastic buckle 1 does not interfere with the bracket 21 during the engagement of the plug 224 and the socket 2151. Next, after the plug 224 and the socket 2151 are in place, rotate the circuit board 22 around the part where the plug 224 and the socket 2151 are engaged, until one end of the elastic member 12 passes through the first through hole 212, and the elastic member 12 is in a compressed state, so that the stop member 13 passes through the first through hole 212; finally, the elastic member 12 springs back, so that the stop member 13 engages with the bracket 21.
[0095] In this embodiment, by providing the third positioning structure 215 and the corresponding insertion part 224, not only can the mating structure between the circuit board 22 and the bracket 21 be improved, thereby enhancing the stability of the circuit board 22 fixed to the bracket 21, but also the circuit board 22 and the third positioning structure 215 engage in a stop-fitting engagement along their insertion direction with the insertion hole 2151, so that one side of the circuit board 22 abuts against the third positioning structure 215, and the other side abuts against the bracket 21 via the elastic member 12. This makes the installation of the circuit board 22 convenient, thereby improving assembly efficiency.
[0096] In conjunction with the foregoing embodiments, the first positioning structure 214 and the second positioning structure 222 cooperate to prevent the circuit board 22 from dislodging in the opposite direction to its insertion into the socket 2151.
[0097] Please see Figure 15 , Figure 15 yes Figure 11 Enlarged view of point G. In some embodiments, the edge of the circuit board 22 is provided with a clearance opening 223. A plug-in portion 224 is disposed in the clearance opening 223. One end of the plug-in portion 224 is connected to the circuit board 22, and the other end is inserted into the socket 2151.
[0098] In this embodiment, by providing a clearance opening 223 and placing the insertion part 224 in the clearance opening 223, the overall size of the circuit board 22 can be controlled, thereby reducing its installation requirements and improving assembly efficiency.
[0099] Please see Figure 14 , Figure 14 yes Figure 13 A cross-sectional view of FF. In some embodiments, an abutment portion 2152 is provided on the wall of the socket 2151 away from the first body 211. The abutment portion 2152 abuts against the portion of the insertion portion 224 inserted into the socket 2151. In this way, the mating portion between the circuit board 22 and the bracket 21 can be increased, thereby improving the positional stability of the circuit board 22 mounted on the bracket 21, and thus improving the reliability of the board 2.
[0100] Please see Figure 6 In some embodiments, there are two third positioning structures 215 and two elastic latches 1. The two third positioning structures 215 are located at two corners on one side of the circuit board 22, and the two elastic latches 1 are located at two corners on the other side of the circuit board 22. In this way, not only can the structure of the board 2 be made symmetrical to improve the stress state of the board 2, but also the reliability of the connection between the circuit board 22 and the bracket 21 can be improved by connecting the circuit board 22 and the bracket 21 through multiple third positioning structures 215 and elastic latches 1, thereby improving the reliability of the board 2.
[0101] Specifically, the circuit board 22 is a rectangular plate structure, with two third positioning structures 215 located at the two corners of one wide side of the circuit board 22, and two elastic buckles 1 located at the two corners of the other wide side of the circuit board 22.
[0102] The circuit board 22 has a connection hole group adjacent to the second socket 2151, and the connection hole group includes multiple pin sockets 225. Multiple connection pins 14 mate with multiple pin sockets 225 in the same connection hole group.
[0103] Please see Figure 2 In some embodiments, the circuit board 22 is provided with a second through hole 221. The connector 11 is located on the side of the circuit board 22 opposite to the first body 211. The elastic member 12 passes through the second through hole 221 and the first through hole 212 on the side away from the connector 11. In this way, not only can the connection status between the metal clip and the circuit board 22 be directly observed during assembly, so as to facilitate smooth assembly; but also during disassembly, the elastic member 12 can be directly compressed from the side of the circuit board 22 opposite to the bracket 21 to disengage the stop member 13 from the bracket 21, making disassembly simple and easy to operate, thereby improving the convenience of maintenance.
