Key structure

Abstract

The invention discloses a key structure. The key structure comprises a bottom plate, a key cap, a first support, a second support, a first magnetic piece, a second magnetic piece and first buffer denoising materials, wherein the first magnetic piece is arranged on the bottom plate and is arranged between the first support and the second support, the second magnetic piece is corresponding to the first magnetic piece and is arranged on the first support, the first magnetic piece is provided with a first part, the second support is provided with a second central end, the first part is adjacent tothe second central end, the first magnetic piece and the second magnetic piece are close relative to each other when the key cap is arranged at a relatively high position, the second magnetic piece is provided with a second part and a third part, the second part props against to the first part, the third part props against the second central end, and the first buffer denoising materials are arranged between the first part and the second part and between the second central end and the third part. A buffer denoising material is arranged at an interference position or a friction position of twomembers, collision or friction is prevented, noise generated by relative action of the members is reduced, and the quietness during key pressing is improved.

Description

technical field [0001] The present invention relates to a key structure, and in particular to a key structure with noise reduction function. Background technique [0002] The keyboard is a hand-type input device that is often used. In order to allow users to use the keyboard flexibly, the magnetic keys are usually equipped with supports and / or balance bars to improve the structural strength of the keycaps, and the keycaps can move up and down relative to the base plate through the supports and / or balance bars. However, when the keycap moves up and down, usually the supporting member or the balance bar will collide with the base plate to generate noise. In addition, friction will be generated at the junction of the support member or the balance bar and the base plate, which may easily generate noise. In addition, the structural interference between the magnetic part and the supporting part is also likely to cause collision and generate noise, which needs to be further improv...

Problems solved by technology

However, when the keycap moves up and down, usually the support or balance bar will collide with the bottom plate to generate noise. In addition, friction will be generated at the junction of the support or balance bar and the bottom plate, which is easy to generate noise

In addition, the structural interference between the magnetic part and the supporting part is also prone to collision and noise, which needs further improvement
