Keyboard key having a haptic elastic piece abutting the return spring

Abstract

A key structure is provided, including a key housing, a keycap, an elastic piece and a spring. The key housing comprises an interfering portion. The keycap is movably assembled to the key housing along a pressing axial direction. The elastic piece is movably assembled to the keycap along the pressing axial direction. The elastic piece comprises a protrusion, and the interfering portion is located on a movement path of the protrusion. The spring abuts between the keycap and the elastic piece. When in an initial position, the protrusion is stopped at the interfering portion. When an external force is applied to the keycap, in a pressing process, the keycap is moved relative to the key housing, and drives the protrusion to surmount and cross over the interfering portion. An elastic restoring force of the elastic piece causes the protrusion to hit the interfering portion to make a sound.
