Title:
ULTRA-THIN BALANCE KEY
Document Type and Number:
WIPO Patent Application WO/2023/201449
Kind Code:
A1
Abstract:
Disclosed in the present invention is an ultra-thin balance key, which is used for triggering an electronic element arranged on a PCB to generate a signal. The ultra-thin balance key comprises a keycap, a bottom board, and a linkage component arranged between the keycap and the bottom board, wherein the linkage component comprises a linkage wing and a trigger wing, which are pivoted to each other; two sides of the linkage wing and the trigger wing each extend to form pivoting arms; tail ends of the pivoting arms of the linkage wing are pivoted to tail ends of the pivoting arms of the trigger wing, and each pivoting arm is provided with a limiting structure; the bottom board is provided with a support component matching the limiting structure to limit the linkage component; and a prizing pivot abutting against the bottom board is formed on one side, which faces the bottom board, of the position of each pivoting arm that is close to the tail end. By means of using the trigger wing and the linkage wing, which are pivoted to each other, structures such as a limiting cover plate are reduced. On the premise of ensuring balanced and stable compression, the up-down moving stroke is further reduced, the linkage components are positioned and cooperate stably, and therefore the key structure can save more materials, and is thinner.
