[0033] The present invention provides a connecting rod type anti-tilting automatic rebound key switch 10, which mainly realizes press-slide control through a sliding bracket 6 arranged in an installation cavity 4 of a main body 1, and combines a connecting rod assembly 7 and a reset spring 11 to provide a vertical thrust to the sliding bracket 6 to achieve reset.

[0034] The main body 1 has an installation cavity 4 inside, and its left and right ends are respectively integrally provided with mutually symmetrical guide grooves 5. A sliding groove 12 that penetrates the wall thickness of the main body 1 is provided at the position of the guide groove 5. The guide groove 5 and the sliding groove 12 are connected to each other. A limiting hole 18 is also provided below the sliding groove 12. A plurality of positioning grooves 15 are provided in the front and rear side walls of the main body 1. A push rod 9 is integrally provided inside the main body 1, and a return spring 11 is provided on the outside of the push rod 9.

[0035] The sliding mechanism 2 is installed in the installation cavity 4 of the main body 1. It includes a sliding bracket 6 and a connecting rod assembly 7. Sliders 8 that cooperate with the guide chute 5 are provided at both the left and right ends of the sliding bracket 6. Moreover, a fastening block 13 is further provided on the slider 8. A number of positioning protrusions 14 that cooperate with the positioning card slots 15 are integrally formed on both the front and rear sides of the sliding bracket 6. The sliding bracket 6 is slidably clamped in the guide chutes 5 at both ends of the main body 1 through the sliders 8 at both ends, and the fastening block 13 is slidably fastened in the sliding card slot 12, preventing the sliding bracket 6 from coming off during the pressing process as a whole. At the same time, the positioning protrusions 14 of the sliding bracket 6 are respectively clamped in the positioning card slots 15, further enabling the sliding bracket 6 to be accurately installed in the main body 1.

[0036] A number of clamping blocks 16 are provided at the bottoms of both the front and rear side walls of the sliding bracket 6. The connecting rod assembly 7 is composed of two independent and identically shaped reset connecting rods 17. The connecting rod assembly 7 is clamped by the clamping blocks 16. A detachable outer cover 26 is provided on each clamping block 16 to prevent the reset connecting rod 17 from falling off the clamping block 16, enabling the two reset connecting rods 17 to be symmetrically arranged at the bottoms of both the front and rear side walls of the sliding bracket 6 respectively.

When the key switch 10 is idle, the sliding bracket 6 stops at the stop position on the main body 1. At this time, the reset spring 11 and the connecting rod assembly 7 still have a certain amount of compressive deformation to provide the required pre-tightening force. When controlling by pressing the touch panel module 23, under the action of the pressing force, the sliding bracket 6 slides along the guide chute 5 in the main body 1. At the same time, the reset spring 11 and the connecting rod assembly 7 are both deformed under the pressing force. When the pressing force disappears, the reset spring 11 will, together with the connecting rod assembly 7, provide a thrust in the vertical direction, enabling the bracket to slide back to its original position smoothly and completing the operation of automatic reset.
