Abstract
The invention relates to a key and a keyboard. The key comprises a bottom plate, a key cap and a supporting device, wherein the supporting device is arranged between the bottom plate and the key cap and comprises a first supporting piece and a second supporting piece which are movably connected with the key cap and the bottom plate. A stop piece is formed on one of the first supporting piece and the key cap. An elastic piece is formed at the place, corresponding to the stop piece, on the other one of the first supporting piece and the key cap, and the elastic piece abuts against the stop piece. When the key cap is not pressed, the stop piece abuts against the elastic piece to maintain the key cap to be in the un-pressed place. When the key cap is pressed and moves to the pressed place along with pivoting of the first supporting piece and the second supporting piece, the key cap and the first supporting piece slide relatively to enable the stop piece to press the elastic piece in a biasing mode to cause the elastic piece to be elastically deformed. When the key cap is released, the elastic piece provides resilience to drive the key cap and the first supporting piece to slide relatively, and the key cap moves to the un-pressed place. The purpose of driving the key cap to be automatically reset as the elastically-deformed elastic piece provides resilience can be achieved.
