The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0034] like Figures 1-10 As shown, this application discloses a Bluetooth key. Figures 1-5 As shown, the Bluetooth key includes a bottom shell 1, a top cover 2, and a control button 4. The top cover 2 is positioned on top of the bottom shell 1, and the top cover 2 and the bottom shell 1 together form a cavity 3. The top cover 2 has a mounting opening 20 that communicates with the cavity 3. The control button 4 is movable up and down and is inserted into the mounting opening 20.

[0035] like Figure 2 , Figure 6 and Figure 7 As shown, the control button 4 includes a button body 41 and an elastic arm 42. The button body 41 is inserted into the mounting opening 20, and the elastic arm 42 is located in the cavity 3. There are at least two elastic arms, which are arranged radially with the button body 41 as the center. The first end of the elastic arm 42 is connected to the outer peripheral wall of the button body 41, and the second end of the elastic arm 42 is fixedly connected to the lower surface of the upper cover 2.

[0036] Understandably, at least two elastic arms 42 are arranged radially, providing sufficient elastic deformation when the button body 41 is pressed, thus preventing the control button 4 from malfunctioning due to insufficient elastic deformation. Furthermore, the at least two elastic arms 42 can apply pressure to different circumferential positions of the button body 41, resulting in more even force distribution on the button body 41. This improves the reliability of the button body 41's up-and-down movement and the pressing feel, while also extending the service life of the control button 4.

[0037] In one implementation, such as Figure 6 and Figure 7 As shown, the aforementioned elastic arm 42 includes an arc-shaped arm 421 extending circumferentially along the button body 41 and arching in a direction away from the button body 41. A gap 43 exists between the inner wall surface of the arc-shaped arm 421 and the outer peripheral surface of the button body 41. The first end of the arc-shaped arm 421 has an extension portion 422 extending towards and connecting to the button body 41. Thus, all the elastic arms 42 are arranged in a clockwise or counterclockwise spiral pattern.

[0038] It is understandable that the elastic arm 42 adopts the form of an arc arm 421. When the button body 41 is in the pressed state, each elastic arm 42 has sufficient elastic deformation, which can improve the reliability of the up and down movement of the button body 41 and extend the service life of the control button 4.

[0039] In one embodiment, the gap 43 between the inner wall surface of the arc-shaped arm 421 and the outer peripheral surface of the button body 41 gradually increases along the circumference of the button body 41. In this embodiment, as... Figure 6 and Figure 7 As shown, along the circumference of the button body 41, the gap 43 between the inner wall surface of the arc-shaped arm 421 and the outer circumferential surface of the button body 41 is of equal size. It can be understood that when the button body 41 moves up and down, the pressure exerted by each arc-shaped arm 421 on the button body 41 is more uniform, making the up and down movement of the button body 41 more reliable.

[0040] In one embodiment, the arc-shaped arms 421 are arranged sequentially along the circumference of the button body 41, with adjacent arc-shaped arms 421 staggered in the radial direction of the button body 41. In this embodiment, the arc-shaped arms 421 are arranged at intervals along the circumference of the button body 41. It is understood that the design of each arc-shaped arm 421 allows for reliable elastic deformation when the control button 4 is in the downward pressing state, thereby providing sufficient movement stroke for the button body 41, improving the movement reliability of the button body 41, increasing the service life of the control button 4, and avoiding the problem of control button 4 failure due to elastic failure.

[0041] like Figure 5 and Figure 7 As shown, the button body 41 includes a button portion 411 located within the mounting opening 20 and a protruding plate 412 extending laterally outward from the bottom periphery of the button portion 411. The protruding plate 412 is located below the mounting opening 20, and its outer periphery is located outside the mounting opening 20. The first end of the elastic arm 42 is connected to the outer periphery of the protruding plate 412. It can be understood that the presence of the protruding plate 412 restricts the control button 4 from being dislodged upward from the mounting opening 20.

[0042] In one embodiment, the second end of the elastic arm 42 is provided with an upwardly extending protrusion, and the lower surface of the upper cover 2 has a socket for inserting the protrusion. The second end of the elastic arm 42 is constrained to the upper cover 2 by the insertion of the protrusion into the socket. In this embodiment, as... Figures 4-7As shown, the lower surface of the upper cover 2 is provided with a downwardly extending extension post 25. The second end of the elastic arm 42 has a socket 423 for inserting the extension post 25, and the extension post 25 is constrained within the socket 423. There are various ways to constrain the extension post 25 to the socket 423, such as welding. In this embodiment, it is fixedly connected to the peripheral wall of the socket 423 by hot riveting. Thus, the installation of the second end of the elastic arm 42 is achieved.

[0043] In addition, such as Figure 5 and Figure 9 As shown, a PCB board 6 is provided inside the cavity 3. The PCB board 6 is constrained to one of the bottom shell 1 and the top cover 2. When the button is in the pressed state, it is electrically connected to the PCB board 6, so that the Bluetooth key works.

[0044] In this embodiment, the PCB board 6 is constrained to the upper cover 2. To facilitate the fixing of the PCB board 6, such as... Figure 9 As shown, the lower surface of the upper cover 2 is provided with a second latch 23 for engaging the PCB board 6. The second latch 23 and the lower surface of the upper cover 2 enclose a limiting groove 7 for the corresponding position of the PCB board 6 to be located therein. The second latch 23 has a second latching foot 231, which is located below the PCB board 6 when the PCB board 6 is engaged with the upper cover 2. There are at least two of the aforementioned second latches 23, which are arranged at intervals along the circumference of the upper cover 2. In this embodiment, there are two second latches 23. The second latching feet 231 of both second latches 23 face the PCB board 6 and are arranged opposite to the first latching feet 221. In other embodiments, there are three or more second latches 23.

[0045] like Figure 2 and Figure 3 As shown, the bottom shell 1 and the top cover 2 are connected by a snap-fit ​​structure 5, and the lower surface of the top cover 2 is provided with a downwardly extending flange 21 near the outer periphery. The inner wall surface of the bottom shell 1 is provided with a support rib 111 at the position corresponding to the flange 21. When the bottom shell 1 and the top cover 2 are in the installed state, the bottom surface of the flange 21 abuts against the top surface of the support rib 111.

[0046] Understandably, the bottom shell 1 and the top cover 2 are connected by a snap-fit ​​structure 5, facilitating their assembly and disassembly. Since the cavity 3 enclosed by the bottom shell 1 and the top cover 2 typically houses the battery, the ease of battery replacement saves time and effort. Because the supporting rib 111 abuts against the flange 21, the contact between the supporting rib 111 and the flange 21 is even tighter when the key is dropped or falls, making the connection between the bottom shell 1 and the top cover 2 more reliable and preventing cracks, openings, or uneven gaps between them.

[0047] like Figure 2 and Figure 3 As shown, the aforementioned snap-fit ​​structure 5 includes a first snap-fit ​​portion and a second snap-fit ​​portion that snaps into the first snap-fit ​​portion. The first snap-fit ​​portion is located on the upper cover 2, and the second snap-fit ​​portion is located on the bottom shell 1. The bottom surface of the first snap-fit ​​portion abuts against the top surface of the support rib 111. It can be understood that the abutment between the bottom surface of the first snap-fit ​​portion and the top surface of the support rib 111 improves the uniformity and reliability of the circumferential connection between the bottom shell 1 and the upper cover 2. In the event of a key being dropped or falling, it further increases the reliability of the connection between the bottom shell 1 and the upper cover 2, and further avoids cracks, openings, or uneven gaps between the bottom shell 1 and the upper cover 2.

[0048] In one embodiment, the first latching portion is a latching inlet, and the second latching portion is a latching insertion portion. Specifically, a protruding plate 412 extends downward from the periphery of the upper cover 2, and the latching inlet is formed on the inner peripheral wall of the protruding plate 412. In this embodiment, as... Figure 2 , Figure 3 and Figure 8 As shown, the bottom shell 1 includes a bottom plate 11 and an extension plate 12 extending upward from the periphery of the bottom plate 11. The first engaging part is a first latch 22, and the second engaging part is a slot 121 formed on the inner peripheral wall of the extension plate 12. The first latch 22 includes a first latching foot 221 that can be engaged into the slot 121. The support rib 111 is located on the upper surface of the bottom plate 11 and below the slot 121.

[0049] like Figure 8 As shown, there are at least three first snap-fit ​​portions, arranged at intervals along the circumference of the upper cover 2. At least one flange 21 is provided between two adjacent first snap-fit ​​portions, and the flange 21 extends along the circumference of the upper cover 2. The following description uses the example shown in the figure with four first snap-fit ​​portions. Two flanges 21 are provided between two adjacent first snap-fit ​​portions, arranged at intervals along the circumference of the upper cover 2.

[0050] In one embodiment, support ribs 111 are provided at positions corresponding to both the flange 21 and the first engaging portion. In this embodiment, as... Figure 2 , Figure 3 and Figure 10 As shown, the bottom shell 1 is provided with a ring of support ribs 111, which extend circumferentially along the bottom shell 1. This facilitates the installation of the support ribs 111, which is not limited by the number of flanges 21 and the first snap-fit ​​portion. One ring of support ribs 111 can abut against each flange 21 and the first snap-fit ​​portion, making processing more convenient.

[0051] In this embodiment, the cross-sections of the bottom shell 1, the top cover 2, and the button body 41 are all circular.

[0052] like Figure 1 and Figure 10As shown, the top edge of the extension plate 12 of the bottom shell 1 has at least two notches 122 for installing the lanyard 8, spaced apart along the length of the extension plate 12. Thus, when installing the lanyard 8, it is only necessary to slip the lanyard 8 onto the portion between the two notches 122, with the portion of the lanyard 8 located within the corresponding notch 122. Furthermore, when the battery needs to be replaced or repaired, the notches 122 can also serve as pry openings to open the top cover 2 and the bottom shell 1, making the disassembly of the Bluetooth key more convenient.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
