Abstract

The invention discloses a key structure, which comprises a key cap, a bottom plate, an elastic body, a thin film switching circuit, a first supporting seat, a second supporting seat, a first metal supporting piece and a second metal supporting piece, wherein the first supporting seat and the second supporting seat are arranged on the bottom plate and are respectively provided with a first side wall and a second side wall; and the first pressing part and the second pressing part of the first metal supporting piece and the second metal supporting piece are connected with the key cap and are rotatably connected with the first side wall and the second side wall via a first L-shaped bending part and a second L-shaped bending part respectively. When the key cap is pressed, the key cap abuts against the first pressing part and the second pressing part from an un-pressed position, the first metal supporting piece and the second metal supporting piece are driven to rotate around the first side wall and the second side wall respectively, and the first supporting and leaning part of the first metal supporting piece and the second metal supporting piece lean mutually and rotate in a linked mode. When the key cap is released, the elastic body provides an upward recovery force to drive the key cap to be recovered to the un-pressed position. Due to arrangement of the thin first metal supporting piece and the second metal supporting piece, thin applications of the key structure is facilitated.

Description

technical field [0001] The invention relates to a key structure, in particular to a thin key structure. Background technique [0002] With the popularization of electronic devices, various input devices are widely used and become a medium for communication between users and electronic devices. Thinning of electronic devices has also become one of the current trends in the industry. In response to this trend, thinning the input device is also one of the directions that researchers are striving to pursue. [0003] Taking a push-operated input device as an example, the traditional key structure uses a supporting structure made of plastic to support the key cap. However, such a support structure requires a large height space, which is not conducive to thinning the input device. Contents of the invention [0004] In order to meet the requirement of thinning the above-mentioned key structure, the present invention provides a key structure. [0005] The above button structure ...
