Abstract

The invention discloses a key structure, which comprises a key cap, a trigger component, a switch circuit board and an elastic component, wherein the trigger component is located on the switch circuitboard, and the elastic component is located between the key cap and the trigger component, which can push against the trigger component due to the moving key cap; and the elastic component is provided with a recessed portion, which is located on the top end of the elastic component and can deform due to pushing of the key cap to increase the distance the key cap moves. Therefore, the key structure of the present invention can improve the touch feeling of a user touching the key cap.

Description

technical field [0001] The invention relates to a key structure, in particular to a key structure with a light and thin appearance. Background technique [0002] Common computer peripheral input devices include a mouse, a keyboard, and a trackball. The keyboard can directly input text and symbols to the computer, so it is highly valued by users and input device manufacturers. Among them, the more common one is a keyboard that includes a scissor-type connecting element. [0003] Next, the architecture of the key structure in the keyboard including the scissor-type connection elements is described. see figure 1 , which is a schematic cross-sectional side view of an existing button structure. The existing button structure 1 includes a button cap 11, a scissors-type connecting element 12, an elastic rubber body 13, a membrane switch circuit 14 and a bottom plate 15, and the bottom plate 15 is used to carry the key cap 11, the scissors-type connecting element 12, the elastic r...
