Title:
ULTRA-THIN KEY
Document Type and Number:
WIPO Patent Application WO/2022/266782
Kind Code:
A1
Abstract:
Disclosed in the present invention is an ultra-thin key. The key is configured to cooperate with an electrical element to output a switch signal, and comprises a key base fitted and provided with a keycap and a triggering element, wherein an elastic reset member is arranged between the triggering element and the key base, and a linkage mechanism for stable stress of the key is arranged between the key base and the keycap. According to the ultra-thin key of the present application, a balancing and tilting rod and a linkage member are used to match each other, so that an ultra-thin structure is achieved, the occurrence of edge warping is effectively reduced by pressing the keycap at any position, the overall stable stress of the keycap is reduced, and triggering is sensitive; and the balancing and tilting rod consisting of a linkage portion, a tilting portion and a transverse connection portion is used, and can achieve stable tilting linkage during a pressing process, and in addition, in cooperation with a perpendicularly arranged limiting groove, the linkage member is not likely to wear out, and has a relatively good linkage stability.
