A key structure and a keyboard using it

Abstract

Disclosed are a keying structure and a keyboard applying same. The keying structure includes a switch button, a heavy load spring, a switch shell, a striking pillar, a light load spring and a thin film circuit, wherein the switch button is clamped at the upper end of the switch shell, the heavy load spring is arranged underneath the switch button, the striking pillar is arranged within the switch shell, and the striking pillar is arranged under the heavy load spring, the light load spring is arranged underneath the striking pillar and the thin film circuit is arranged underneath the light load spring. During use, the switch button is pressed with a hand and, depressed under pressure, transfers a down force to the heavy load spring; the heavy load spring transfers the down force to the striking pillar, and the striking pillar depresses the light load spring to make the lower part of the striking pillar contact with the thin film circuit, thus making the thin film circuit conduct. The sensitivity of the present invention is high, the invention also has a downward idle motion, improving the feel to the hand for the player, and is low in cost.

Description

technical field [0001] The present invention relates to the technical field of keys used in computers or game machines, and more specifically relates to a key structure and a keyboard using the same. Background technique [0002] At present, computer keyboards mostly use a combination structure of a single key switch. A single key is usually composed of a keycap, a push rod, a silicone elastic piece and a thin film circuit. The thin-film circuit is set under the silicone elastic piece. When in use, the push rod is pressed down by pressing the keycap, and then pressed down on the thin-film circuit through the silicone elastic piece, so that the thin-film circuit is turned on, thereby When the input effect is reached, let go of the keycap, and under the elastic force of the silicone elastic piece, the push rod goes up to disconnect the membrane circuit. The button with this structure has only two states, one is off and the other is on. After the push rod is turned on, there i...

Problems solved by technology

If the button of this structure is applied to the game keyboard, it has the following disadvantages: one, the player's hand feeling is relatively poor; two, the sensitivity is not high

[0003] Another existing game-specific keyboard can also have an empty stroke to go down after it is turned on, but its cost is high and the price is expensive.
