key structure

Abstract

The invention relates to a button structure. The button structure comprises a keycap, balance rods, a base plate, and a buffer plate, wherein the keycap comprises combination portions and a lower surface, the combination portions protrude from the lower surface, and when the keycap is pressed, the keycap moves downwardly to a decrease position; the balance rods are connected to the combination portions, and when the keycap is positioned at the decrease position, the lower points of the combination portions are lower than the balance rods; the base plate is arranged below the keycap, the base plate comprises recessed spaces corresponding to the combination portions, the buffer plate is arranged on the base plate, the buffer plate covers the recessed spaces and comprises deformable portions corresponding to the recessed spaces, and when the keycap moves to a lower position towards the base plate, the lower points of the combination portions are abutted against the deformable portions, and the deformable portions extend into the recessed spaces. According to the buffer design of the button structure, buffer elasticity can be provided during button operation, noises generated by direct collision with the base plate of the keycap can be avoided or reduced, and a multilayer structure of a membrane switch forms the buffer design so that the material cost is not increased, and the function of noise reduction can be effectively performed.

Description

technical field [0001] The present invention relates to a key structure, in particular, the present invention relates to a key structure with mute design and a keyboard device with the key structure. Background technique [0002] The keycaps of multiple keys (such as space (Space) key, carriage return (Enter) key, uppercase and lowercase switching (CapsLock) key, displacement (Shift) key, etc.) A balance bar is provided to improve the structural strength of the keycap. Furthermore, with the setting of the balance bar, even if the user presses the non-central position of the keycap, the multiplier key will not be tilted during the pressing process. The balance bar is generally connected to the bottom of the keycap by engaging with the joint part protruding from the lower surface of the keycap. When the user presses the keycap, along with the downward movement of the keycap, usually the protruding joint portion below the keycap collides with the bottom plate to generate nois...

AI Technical Summary

Problems solved by technology

When the user presses the keycap, with the downward movement of the keycap, usually the protruding joint under the keycap will collide with the bottom plate and generate noise, which will affect the smoothness and comfort of the operation
