Button structure and keyboard

Abstract

The invention relates to a key structure and a keyboard. The key structure comprises a supporting plate, a key cap, a frame and a pair of second magnetic areas. The supporting plate is provided a first fitting part which is extended along the direction of the Z axis. The key cap is provided with a second fitting part which is extended along the direction of the Z axis and movably inserted in the first fitting part. When pressure is applied on the key cap, the key cap moves toward the supporting plate, and the first fitting part and the second fitting part relatively move along the direction of the Z axis. The frame is provided with a space and a pair of first magnetic areas located on the opposite sides of the space, and the key cap can move up and down in the space. The pair of second magnetic areas are arranged on the opposite sides of the key cap and respectively correspond to the pair of first magnetic areas, and when pressure is released, the key cap moves away from the supporting plate along the direction of the Z axis by means of the magnetic force provided by the interaction between the pair of second magnetic areas and the pair of first magnetic areas. By utilizing a magnetization process to form the frame with the first magnetic areas, the number of the second magnetic areas is effectively reduced and the complexity of assembly is simplified, so that the efficiency of assembly is increased.

Description

technical field [0001] The invention relates to a key structure and a keyboard, in particular, the invention relates to a key structure with a frame of a magnetic area and a keyboard. Background technique [0002] The conventional button structure usually utilizes an elastic body to provide the power for the keycap to rise and return after being pressed, and uses a scissor-like support to support the stability of the keycap's lifting. However, as the requirement for thinner and thinner is getting higher and higher, the conventional button structure is limited by the volume of the elastic body and the lifting characteristics of the scissor-type supporting member, so the size limit has been reached. In addition, when the scissor support is assembled, the four supporting ends of the scissor support must be respectively connected to the keycap and the support plate, which makes the assembly work very complicated. [0003] Furthermore, how to reduce the number of assembled compo...
