Key structure

Abstract

The invention relates to a key structure. The key structure comprises a base, a keycap, a lifting mechanism and a magnetic part; the keycap can move vertically relative to the base through the lifting mechanism; the lifting mechanism comprises a support; one lateral side portion of the support comprises a magnetic portion; the lateral side portion is in abutting joint with the base through a sharp edge; the magnetic portion extends outward from the lateral side portion; the support is flexibly connected with the keycap through an opposite lateral side portion; the magnetic part is arranged on the base corresponding to the magnetic portion; the magnetic suction force is produced between the magnetic part and the magnetic portion; when the keycap is pressed by the external force, the support rotates relative to the base through the sharp edge to enable the magnetic portion to be far away from the magnetic part and the keycap to be close to the base; when the external force is released, the support is driven by the magnetic suction force to rotate relative to the base through the sharp edge to enable the keycap to be far away from the base; the base can be provided with a magnetic part, wherein the magnetic suction force can be applied to the other magnetic portion of the support to drive the lateral side portion to be in abutting joint with the base.

Description

technical field [0001] The invention relates to a key structure, in particular to a mechanical key structure. Background technique [0002] The distance of the up and down movement of the traditional key is longer, so it is easy to set the bowl-shaped rubber body under the key cap, so that when the key cap is pressed down, the bowl-shaped rubber body is also compressed downward to generate elasticity, and When the keycap is released, the elastic force generated by the bowl-shaped rubber body drives the keycap to move upward to return to its original position. However, with the trend of thinner keyboards, when the height of the keyboard’s up and down movement is required to be reduced, the height of the bowl-shaped rubber body must also be reduced. However, when the height of the bowl-shaped rubber body is reduced, the characteristics of life and elasticity will deteriorate. . In addition, for longer keys (also known as multiple keys), usually a plurality of connecting rods...

However, with the trend of thinner keyboards, when the height of the keyboard’s up and down movement is required to be reduced, the height of the bowl-shaped rubber body must also be reduced. However, when the height of the bowl-shaped rubber body is reduced, the characteristics of life and elasticity will deteriorate.

In addition, for longer keys (also known as multiple keys), usually a plurality of connecting rods are arranged at the bottom of the key cap so that when the user presses any position on the key cap, it can indeed keep moving up and down horizontally and allow the user to feel To achieve a clear resilience (or feel), but as the height of the keyboard is required to be lowered, due to space constraints, this design is not easy to implement
