[0025] The present invention provides a key structure 100 .

[0026] See also Figures 1 to 6 In one embodiment of the present invention, the key structure 100 includes a key base 1 and a PCB board 2, and the key base 1 is provided with a slot 11; the PCB board 2 passes through the notch of the slot 11 and is slidably limited in the slot 11.

[0027] In the technical solution of the present invention, the PCB board 2 is slid into the notch of the card slot 11 and is limitedly installed in the card slot 11, thereby completing the quick installation of the PCB board 2; when the PCB board 2 needs to be replaced or maintained, the PCB board 2 is pulled out from the notch of the card slot 11 to complete the disassembly of the PCB board 2, which greatly reduces the difficulty of disassembling and assembling the PCB board 2, simplifies the assembly process of the PCB board 2, and improves the convenience of maintenance; the card slot 11 can be a plate provided on both sides of the button seat 1, and each plate has a card slot 11 on the opposite side, so that the two sides of the PCB board 2 are limited to slide in the card slot 11, or a card slot 11 is provided on one side of the button seat 1, and the inner peripheral wall of the installation groove is provided with a card slot 11, so that the PCB board 2 is limited to slide in the card slot 11. The present invention does not impose any restrictions on this.

[0028] Specifically, see Figure 2In the technical solution of the present utility model, two positioning plates 12 are provided on one side of the button seat 1, and a support column 19 and an elastic limiting arm 14 are provided on each positioning plate 12. The elastic limiting arm 14 and the support column 19 enclose the card slot 11. The support columns 19 on each positioning plate 12 provide support on both sides of the PCB board 2, which can effectively prevent the PCB board 2 from shaking or deflecting in the key seat 1, ensuring the stability and normal function of the structure; the elastic limiting arms 14 and the support columns 19 clamp and limit the PCB board 2 through the formed slots 11. The elastic characteristics of the elastic limiting arms 14 allow them to automatically adjust during the clamping process to adapt to slight size changes or thickness differences of the PCB board 2, ensuring the stable positioning of the PCB board 2 in the key seat 1. The design of the elastic limiting arms 14 can also reduce the pressure on the PCB board 2, thereby preventing the PCB board 2 from being subjected to excessive mechanical stress during the fixing process and reducing the risk of damage; this structural design makes the installation and maintenance process of the PCB board 2 simpler. The user can easily insert the PCB board 2 into the slots 11, and the elastic limiting arms 14 will automatically clamp the PCB board 2 and maintain its position, avoiding tedious fixing operations; the support columns 19 can be set on each positioning plate 12, or multiple can be set on each positioning plate 12, and the present invention does not impose any restrictions on this.

The positioning protrusion 13 is snapped into the positioning groove 21. The precise fit between the positioning protrusion 13 and the positioning groove 21 can effectively prevent the PCB board 2 from being misplaced or tilted, ensuring its correct position within the button base 1 and improving the accuracy of the installation process. By using the positioning protrusion 13 and the positioning groove 21, the user only needs to align the PCB board 2 with the positioning protrusion 13 and the positioning groove 21 when installing it, and automatic alignment is achieved, simplifying the installation process. The snap-fit ​​mechanism of the positioning protrusion 13 and the positioning groove 21 provides additional physical fixing force, ensuring the stability of the PCB board 2 during use and preventing the PCB board 2 from moving due to vibration or other external factors. This design also simplifies maintenance and replacement processes. Because the positioning protrusion 13 and the positioning groove 21 provide clear docking points, maintenance personnel can more easily and accurately install or replace the PCB board 2.
