Document Type and Number:
WIPO Patent Application WO/2016/183982
Kind Code:
A1
Abstract:
Disclosed is a key structure of a scissor keyboard, comprising: a base (1), a thin film circuit board (2) arranged on the base (1), an elastic member (3) arranged on the thin film circuit board (2), a scissor support (4) arranged above the elastic member (3) and mounted on the base (1), and a key cap (5) mounted on the scissor support (4), wherein the scissor support (4) comprises an inner support (41), and an outer support (42) rotatably connected to the outer side of the inner support (41); an overhead portion (43) is formed below a rotating joint of the inner support (41) and the outer support (42), and the elastic member (3) is located in the overhead portion (43); and the inner support (41) and the outer support (42) of the scissor support (4) form a dual-lever mechanism, a protrusion (415) is arranged at one side of the inner support (41) facing the elastic member (3), the thin film circuit board (2) is provided with a circuit contact, the elastic member (3) correspondingly covers the circuit contact, and when the key cap (5) is pressed, the protrusion (415) of the scissor support (4) presses the elastic member (3), and the elastic member (3) presses the thin film circuit board (2) so as to make the circuit contact of the thin film circuit board conduct by contact. The scissor dual-lever mechanism is used to arrange a pressing point of a press elastic member on the inner support of the scissor support, such that the overall key is thinner, the stroke is larger, and the hand feel is better, thereby meeting the requirements of being ultra-portable for electronic products, and the striking force at each position of the key cap is small and balanced when in use, the hand feel is comfortable, the sound is low, and the structure is simple.
