[0058] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0060] Furthermore, although the terminology used in this application is selected from commonly known and used terms, some terms mentioned in this application specification may have been selected by the applicant at his or her own discretion, and their detailed meanings are explained in the relevant sections of this description.

[0061] Furthermore, this application is required to be understood not only through the actual terms used, but also through the meaning implied by each term.

[0062] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0063] This application provides an electronic device. (See reference...) Figures 1 to 29 The electronic device 1 provided in this application embodiment includes: a bracket 100, an elastic buckle 200, a mounting frame 300, and a first circuit board 400.

[0064] refer to Figure 4 , Figures 10 to 13 The bracket 100 is provided with a first connecting groove 110, and the elastic buckle 200 is connected to the first connecting groove 110. The elastic buckle 200 is provided with a first elastic protrusion 211, which protrudes from the outer surface of the bracket 100.

[0065] refer to Figure 3 The mounting frame 300 is provided with a receiving groove 310 that is open along the thickness direction of the electronic device 1. (Reference) Figure 17 and Figure 18 The accommodating groove 310 has a second connecting groove 311 on its groove wall.

[0066] refer to Figure 1 , Figure 2 , Figure 17 and Figure 18The bracket 100 is housed in the receiving groove 310, and the first elastic protrusion 211 is inserted into the second connecting groove 311. The first elastic protrusion 211 abuts against the groove wall of the second connecting groove 311 along the thickness direction of the electronic device 1 to prevent the bracket 100 from moving along the thickness direction of the electronic device 1. The first circuit board 400 is disposed on the side of the bracket 100 facing the bottom of the receiving groove 310, and the elastic buckle 200 is disposed on the side of the first circuit board 400 away from the bottom of the receiving groove 310.

[0067] In this way, in the embodiments of this application, the elastic buckle 200 provided at the first connecting groove 110 of the bracket 100 can be used to confine the bracket 100 within the receiving groove 310 of the mounting frame 300, thereby eliminating the need for screws that would otherwise be required to connect there. This also avoids the need to create a clearance recess on the first circuit board 400 opposite to the elastic buckle 200. Therefore, it can increase the area of ​​the first circuit board 400, thereby increasing the area of ​​the component placement area on the circuit board.

[0068] The above embodiments mainly provide a solution for limiting the bracket 100 in the receiving groove 310 by using the elastic buckle 200. Below, a solution that can improve the ease of disassembly of the bracket 100 is also provided.

[0069] refer to Figure 19 and Figure 20 In some embodiments, the elastic buckle 200 is further provided with a driving sub-part 212. The driving sub-part 212 is connected to the first elastic protrusion sub-part 211. When the driving sub-part 212 is driven by an external force, the driving sub-part 212 drives the first elastic protrusion sub-part 211 to move away from the second connecting groove 311, so as to separate from the second connecting groove 311.

[0070] For example, a driving force can be applied to the drive sub-part 212 via the first disassembly tool 800, causing the drive sub-part 212 to move the first elastic protruding sub-part 211 in a direction away from the second connecting groove 311. For example, the drive sub-part 212 can be a disassembly baffle. The first disassembly tool 800 can be tweezers, a pin, or a screwdriver, etc. Figure 19 and Figure 20 The first disassembly tool 800 can press down on the drive sub-part 212, thereby causing the first elastic protruding sub-part 211 to move to the right and separate from the second connecting groove 311.

[0071] refer to Figures 10 to 12 In some embodiments, the bracket 100 is provided with a through hole 115 communicating with the first connecting groove 110. When the elastic buckle 200 is connected to the first connecting groove 110, the end of the first elastic protrusion 211 is exposed to the outer surface of the bracket 100 through the through hole 115.

[0072] refer to Figure 19 and Figure 20 In some embodiments, when the bracket 100 is confined within the receiving groove 310, the side of the first elastic protrusion 211 facing away from the first circuit board 400 is spaced apart from the wall of the through hole 115. The distance between the side of the first elastic protrusion 211 facing away from the first circuit board 400 and the wall of the through hole 115 is L1. It should be noted that the size of L1 can be flexibly set according to actual conditions. In this way, by spaced apart from the wall of the through hole 115 on the side of the first elastic protrusion 211 facing away from the first circuit board 400, the first elastic protrusion 211 can move to the upper right when the driving part 212 is driven by an external force, thereby separating from the second connecting groove 311.

[0073] It should be noted that in some embodiments, the driving part 212 may not be provided. For example, the first elastic protrusion 211 can be retracted by disrupting the shape of the elastic buckle 200, thereby separating the first elastic protrusion 211 from the second connecting groove 311. For example, the shape of the elastic buckle 200 can be disrupted by using pliers to deform it, thereby causing the first elastic protrusion 211 to retract.

[0074] refer to Figure 13 In some embodiments, the elastic buckle 200 is further provided with a second elastic protrusion 213, which is opposite to the first elastic protrusion 211. The groove wall of the first connecting groove 110 is provided with a first recess 111, and the second elastic protrusion 213 engages with the first recess 111.

[0075] In this way, the elastic buckle 200 can be confined in the first connecting groove 110 along the thickness direction of the electronic device 1 by engaging the second elastic protrusion 213 with the first recess 111. Furthermore, by engaging the second elastic protrusion 213 with the first recess 111, the elastic buckle 200 can be prevented from shifting relative to the groove wall of the first connecting groove 110 along the line connecting the second elastic protrusion 213 and the first elastic protrusion 211.

[0076] refer to Figure 14 In some embodiments, the elastic buckle 200 further includes a third elastic protrusion 214 and a fourth elastic protrusion 215, which are opposite to each other. The groove wall of the first connecting groove 110 is provided with a second recess 112 and an abutment wall 113. The third elastic protrusion 214 engages with the second recess 112, and the fourth elastic protrusion 215 abuts against the abutment wall 113.

[0077] In this way, the elastic buckle 200 can be confined in the first connecting groove 110 along the thickness direction of the electronic device 1 by engaging the third elastic protrusion 214 with the second recess 112. Furthermore, by engaging the third elastic protrusion 214 with the second recess 112 and abutting the fourth elastic protrusion 215 against the abutting wall 113, the elastic buckle 200 can be prevented from shifting relative to the groove wall of the first connecting groove 110 along the line connecting the third elastic protrusion 214 and the fourth elastic protrusion 215.

[0078] refer to Figure 14 In some embodiments, the elastic buckle 200 also includes a folded edge 216. A clearance portion 114 is provided on the side wall of the first connecting groove 110 opposite to the folded edge 216, and the folded edge 216 and the clearance portion 114 are spaced apart. Figure 4 For example, the clearance portion 114 can be a clearance slope provided on the side wall of the first connecting groove 110. The distance between the folded edge 216 and the clearance portion 114 is L2. It should be noted that the size of L2 can be flexibly set according to the actual situation.

[0079] In this way, the elastic buckle 200 can be removed from the first connecting groove 110 by inserting the second disassembly tool under the folded edge 216 and prying the folded edge 216 upward. This facilitates the replacement of the elastic buckle 200 if it is damaged.

[0080] In some embodiments, the resilient buckle 200 is a metal buckle. (See reference) Figure 16 The first circuit board 400 has a conductor portion 410, and the elastic buckle 200 is electrically connected to the conductor portion 410. The conductor portion 410 is electrically connected to the mounting frame 300. For example, the elastic buckle 200 has a fifth elastic protrusion 217. The fifth elastic protrusion 217 elastically abuts against the conductor portion 410. Further, the conductor portion 410 can be electrically connected to the mounting frame 300 via a metal screw or a metal spring. This allows the metal buckle to be electrically connected to the mounting frame 300 via the conductor portion 410 of the first circuit board 400.

[0081] It should be noted that, generally speaking, the mounting frame 300 serves as the "ground" of the electronic device 1. Using the solution provided in this application embodiment, the metal buckle can be grounded by electrically connecting it to the mounting frame 300. This prevents the metal buckle from generating interference signals when the electronic device 1 is in operation. Specifically, when signal cables are present near the metal buckle, the signals in the cables may be AC ​​signals, which can induce an electric field on the metal buckle. This induced electric field on the metal buckle can be considered as interference. In the embodiments of this application, grounding the metal buckle prevents the generation of an induced electric field.

[0082] This application also provides another type of flexible buckle 200. (See reference...) Figure 21 and Figure 22 In some embodiments, the elastic buckle 200 includes a latching portion 210 and a cable connecting portion 220 connected together. The latching portion 210 is inserted into the first connecting groove 110, and the first elastic protrusion 211 is disposed in the latching portion 210. It is understood that, in combination with... Figure 21 and Figure 5 It can be seen that, Figure 21 The elastic buckle 200 shown is equivalent to... Figure 5 Based on the elastic buckle 200 shown, a cable connection part 220 is further added.

[0083] refer to Figures 23 to 29 In some embodiments, the electronic device 1 further includes a connecting cable 500. The connecting cable 500 is electrically connected to the first circuit board 400, and the connecting cable 500 includes a shielding sleeve 510, which is electrically connected to the cable connection portion 220. In this way, by electrically connecting the shielding sleeve 510 to the cable connection portion 220, the connecting cable 500 can be indirectly grounded via the elastic buckle 200, thereby improving the anti-interference performance of the connecting cable 500.

[0084] refer to Figures 23 to 27 In some embodiments, the bracket 100 is embedded with a metal insert 120. The cable connector 220 is fixedly connected to and electrically connected to the metal insert 120. Exemplarily, the cable connector 220 and the metal insert 120 can be fixedly connected and electrically connected by welding. The cable connector 220 is provided with a clamping sub-part 221, and a shielding sleeve 510 is connected to the clamping sub-part 221. Exemplarily, the shielding sleeve 510 includes an exposed area 511, which can be clamped to the clamping sub-part 221.

[0085] It should be noted that, generally, the outermost layer of the connecting cable 500 is covered with an insulating layer. This insulating layer can be removed from the exposed area 511, exposing this area of ​​the shielding sleeve 510 to the outer surface of the connecting cable 500, thus forming the exposed area 511. Furthermore, the clamping part 221 can be connected to the shielding sleeve 510 of the connecting cable 500 via the exposed area 511. Further, the elastic buckle 200 can be electrically connected to the mounting frame 300, allowing the shielding sleeve 510 of the connecting cable 500 to be indirectly grounded via the elastic buckle 200.

[0086] refer to Figures 24 to 27In some embodiments, the bracket 100 is provided with a insertion slot 130. One end of the cable connector 220 opposite to the latching part 210 is inserted into the insertion slot 130. In this way, the cable connector 220 can be limited along the thickness direction of the electronic device 1 by inserting one end of the cable connector 220 opposite to the latching part 210 into the insertion slot 130.

[0087] In some embodiments, the first circuit board 400 is an antenna circuit board. The bracket 100 is a speaker bracket. (Reference) Figure 2 and Figure 3 The electronic device 1 also includes a second circuit board 600, which is disposed on the side of the bracket 100 facing the bottom of the receiving groove 310. Exemplarily, the second circuit board 600 is a sub-board of the electronic device 1.

[0088] Further, refer to Figure 1 The electronic device 1 also includes a third circuit board 710. For example, the third circuit board 710 is the main board of the electronic device 1. Exemplarily, the antenna circuit board can be electrically connected to both the main board and the sub-board. For example, the electronic device 1 can supply power to the antenna circuit board via the sub-board, and the signals generated by the antenna circuit board can be transmitted to the main board.

[0089] In addition, the electronic device 1 also includes a battery 720. For example, in the case where the electronic device 1 is a mobile phone, the mounting frame 300 is the mobile phone's mid-frame. The mounting frame 300 may have three receiving slots. The three receiving slots are respectively used to receive the motherboard, the battery, and the sub-board.

[0090] In some embodiments, when the resilient buckle 200 is a metal buckle, the metal buckle can be manufactured by a stamping process or a bending process. For example, refer to... Figure 9 The first elastic protrusion 211 is formed by a first bent segment 2111 and a second bent segment 2112. The angle between the first bent segment 2111 and the vertical line is α1. For example, combined with... Figure 11 The angle between the first bent section 2111 and the vertical line can be less than 45 degrees, so that the first elastic protrusion 211 can be inserted into the through hole 115. (Continue to refer to...) Figure 9 The angle between the second bending segment 2112 and the vertical line is a2. For example, combined with... Figure 18 The angle between the second bent section 2112 and the vertical line can be greater than 60 degrees, so as to prevent the first elastic protrusion 211 from accidentally exiting the second connecting groove 311.

[0091] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0092] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the embodiments of this application, the scope of which is defined by the appended claims and their equivalents.
