Problems solved by technology

However, as the requirements for thinner and thinner are getting higher and higher, the conventional button structure is limited by the volume of the elastic body and the lifting characteristics of the support member, so it has reached the limit of size restriction.

Embodiment Construction

[0038] The present invention provides a button structure, which can be applied to any push-type input device, such as a keyboard, so as to effectively reduce the height of the buttons, simplify assembly complexity and satisfy the user's pressing habits. The structure and operation of each element of the key structure according to the embodiment of the present invention will be described in detail below with reference to the drawings.

[0039] Figure 1A It is a top exploded view of the button structure of the first embodiment of the present invention, Figure 1B for Figure 1A The upward exploded view of the key structure. Such as Figure 1A and Figure 1B As shown, the key structure 100 includes a bottom plate 110, a keycap 120, a frame 130, a first magnetic member 140, and a movable plate 160, wherein the keycap 120 is arranged above the bottom plate 110 and can move relative to the bottom plate 110, and the frame 130 corresponds to the keycap The key cap 120 is disposed a...

Abstract

The invention relates to the key structure. The key structure comprises a bottom plate, a key cap, a frame, a first magnetic part and a moving plate, wherein the key cap is movably arranged above the bottom plate relative to the bottom plate, the frame with a key opening is arranged in correspondence to the key cap, the first magnetic part and the moving plate are arranged in the frame, and the key cap moves in the key opening relative to the bottom plate. The moving plate is provided with a first end and a second end which corresponds to the key cap and the first magnetic part, the second end is provided with a second magnetic part, and the second magnetic part and the first magnetic part can generate magnetic attraction. When the key cap is pressed to move towards the bottom plate, the key cap drives the moving plate to rotate relative to the frame so that the second magnetic part is distant from the first magnetic part. When the pressure is released, the moving plate can reversely rotate relative to the frame by the aid of the magnetic attraction, so that the second magnetic part is close to the first magnetic part so as to drive the key cap to move away from the bottom plate.

Description

technical field [0001] The invention relates to a button structure, in particular, the invention relates to a magnetic suction button structure. Background technique [0002] The conventional key structure usually utilizes an elastic body to provide the power for the keycap to rise and return after being pressed, and supports the stability of the keycap to lift up and down through the supporting member. 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 supporting member, so the limit of size restriction has been reached. [0003] Furthermore, how to achieve the familiar pressing feel of users under the requirement of thinning and lightening has become the focus of the key structure research and development. Contents of the invention [0004] The purpose of the present invention is to provide a key structure, which uses magne...
