THIN NOTEBOOK COMPUTER MECHANICAL KEYBOARD

WIPO Patent Application WO/2016/138803

A1

Provided in the invention is a thin notebook computer mechanical keyboard. The keyboard comprises: a reinforcement iron plate, a scissor foot, a keycap, a base, a pressing stopper, a spring and a cover. The reinforcement iron plate is arranged on a circuit board and provided with a hollow groove and a plurality of clamping parts at corners thereof. The scissor foot is provided with a plurality of first positioning parts and a plurality of second positioning parts. The first positioning parts are vertically and movably clamped on the clamping parts, and the scissor foot is hollow. The keycap is provided with a plurality of fastening parts. The fastening parts are fastened on the second positioning parts. When the keycap is pressed to a certain extent, an action between a hand touch and a fourth terminal produces a sound of an upward impact against the cover. Moreover, when the keycap is pressed, the scissor foot maintains the balance of the whole keycap without catching the keycap, ensuring a favorable touch feeling; a switch is directly installed on a PCB and passes through the reinforcement iron plate; thus, the scissor foot structure maintains the balance of the keycap, and balanced movement is achieved without falling short of thinning requirements.
