[0001] This application relates to the field of key technology, and in particular to a remote control key. Background Technology
[0002] Existing remote control keys can control the opening / locking of door locks, enabling remote opening and locking of doors. A remote control key typically consists of a base and a top cover. The space enclosed by the base and top cover houses the battery, PCB board, and other components.
[0003] In existing remote control keys, the bottom shell and top cover are fixed together with screws. When the battery needs to be replaced or repaired, special tools are required to remove the screws, which is cumbersome. After replacing the battery, the screw holes on the bottom shell and top cover must be aligned before the screws can be installed using special tools, making the entire installation process cumbersome and causing great inconvenience to users. In addition, when the remote control key is dropped or fallen, it can easily cause uneven gaps between the top cover and the bottom shell. Utility Model Content
[0004] Therefore, it is necessary to provide a remote control key that is easy and quick to assemble and disassemble and is reliable in assembly.
[0005] This application provides a remote control key, including a bottom shell and a top cover disposed on the bottom shell. The top cover is provided with a control button. The bottom shell and the top cover are connected by a snap-fit structure. The lower surface of the top cover is provided with a downwardly extending flange near the outer periphery. The inner wall surface of the bottom shell is provided with a support rib at the position corresponding to the flange. When the bottom shell and the top cover are in the installed state, the bottom surface of the flange abuts against the top surface of the support rib.
[0006] In one embodiment, the snap-fit structure 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 disposed on the upper cover, and the second snap-fit portion is disposed on the bottom shell. The bottom surface of the first snap-fit portion abuts against the top surface of the support rib.
[0007] In one embodiment, the bottom shell includes a bottom plate and an extension plate extending upward from the periphery of the bottom plate. The first snap-fit portion is a first buckle, and the second snap-fit portion is a slot formed on the inner peripheral wall of the extension plate. The first buckle includes a first snap foot portion that can snap into the slot. The support rib is located on the upper surface of the bottom plate and below the slot.
[0008] In one embodiment, there are at least three first snap-fit portions, which are arranged at intervals along the circumference of the upper cover, and at least one flange is provided between two adjacent first snap-fit portions, the flange extending along the circumference of the upper cover.
[0009] In one embodiment, the bottom shell and the top cover together form a cavity, and a PCB board that can be electrically connected to the control button is disposed in the cavity. The PCB board is constrained to one of the bottom shell and the top cover.
[0010] In one embodiment, the lower surface of the upper cover is provided with a second buckle for engaging the PCB board, and the second buckle and the lower surface of the upper cover form a limiting groove for the corresponding position of the PCB board to be located therein.
[0011] In one embodiment, there are at least two second buckles, which are arranged at circumferential intervals along the top cover.
[0012] In one embodiment, a positioning post and a positioning hole are provided between the upper surface of the bottom shell and the lower surface of the top cover, and one of the positioning post and the positioning hole is provided on the upper surface of the bottom shell, and the other of the positioning post and the positioning hole is provided on the lower surface of the top cover.
[0013] In one embodiment, the bottom shell includes a bottom plate and an extension plate extending upward from the periphery of the bottom plate.

[0030] like Figures 1-6 As shown, this application discloses a remote control key. Figures 1-3 As shown, the remote control key includes a bottom shell 1 and an upper cover 2 covering the bottom shell 1. The upper cover 2 is provided with a control button 4. The bottom shell 1 and the upper cover 2 are connected by a snap-fit structure 5. The lower surface of the upper 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 upper cover 2 are installed, the bottom surface of the flange 21 abuts against the top surface of the support rib 111.
[0031] 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.
[0032] 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.
[0033] 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 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. In this embodiment, as shown... Figure 2 and Figure 3 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.
[0034] 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 an example with four first snap-fit portions as shown in the figure. Figure 4 As shown, two flanges 21 are provided between two adjacent first snap-fit portions, arranged circumferentially along the upper cover 2.
[0035] 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 6 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.
[0036] like Figure 2 and Figure 3 As shown, the bottom shell 1 and the top cover 2 together form a cavity 3. A PCB board 6, electrically connected to the control button 4, is disposed within the cavity 3. The PCB board 6 is constrained to one of the bottom shell 1 and the top cover 2. In one embodiment, the PCB board 6 is constrained to the bottom shell 1. When the control button 4 is arranged to move up and down relative to the top cover 2, and is in a downward-pressed state, it is electrically connected to the PCB board 6, and the remote control key operates.
[0037] 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... Figures 2-5 As shown, the lower surface of the upper cover 2 is provided with a second latch 23 for engaging the PCB board 6. The aforementioned flange 21 and the first latch 22 are both located around the second latch 23. 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. 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 second latches 23, 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 aforementioned first latching feet 221. In other embodiments, there are three or more second latches 23.
[0038] like Figure 5 and Figure 6As shown, a positioning pin 24 and a positioning hole 13 are provided between the upper surface of the bottom shell 1 and the lower surface of the top cover 2, which are designed to interlock. One of the positioning pin 24 and the positioning hole 13 is located on the upper surface of the bottom shell 1, and the other is located on the lower surface of the top cover 2. It can be understood that the precise positioning of the bottom shell 1 and the top cover 2 can be achieved through the cooperation of the positioning pin 24 and the positioning hole 13. After positioning, only pressing the bottom shell 1 and the top cover 2 is required to assemble them. The entire process is convenient, quick, and saves time and effort.
[0039] In one embodiment, the positioning post 24 is located on the upper surface of the upper cover 2 and extends upward, and the positioning hole 13 is located on the upper surface of the bottom shell 1. In this embodiment, the positioning post 24 is located on the lower surface of the upper cover 2 and extends downward, and the positioning hole 13 is located on the lower surface of the bottom shell 1.
[0040] like Figure 1 and Figure 6 As 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 removal of the remote control key more convenient.
[0041] In this embodiment, the cross-sections of both the bottom shell 1 and the top cover 2 are circular.
[0042] 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.
[0043] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are 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.
