Problems solved by technology

[0004] However, due to the scissor foot mechanism design adopted by the support device 16, it requires a larger height space, thereby further increasing the overall height of the key 1, which is not conducive to the application of thin keyboards.
In addition, the elastic member 18 is usually made of rubber, and the rubber will be fatigued under long-term use, thereby shortening the service life of the button 1

Embodiment Construction

[0038] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0039] see figure 2 , which is a perspective view of the keyboard 100 proposed according to the first embodiment of the present invention. Such as figure 2 As shown, the keyboard 100 includes a base plate 102 and a plurality of keys 104 , the keys 104 are disposed on the base plate 102 , and the keys 104 are used for pressing by a user to execute functions desired by the user. The keyboard 100 is preferably a keyboard commonly used in personal computers, but not limited thereto. For example, the keyboard 100 can also be applied to portable electronic devices (such as notebook computers or folding keyboards) generally having an opening and closing mechanism composed of an upper cover and a lower casing.

Abstract

The invention provides a key and a keyboard comprising the key. The key comprises a bottom plate, a key cap, a sliding way, a protruding part and two magnetic parts, wherein the key cap can move between the pressing position and the releasing position relative to the bottom plate and is provided with the protruding part, the sliding way is arranged between the bottom plate and the key cap, and the two magnetic parts abut between the protruding part and the sliding way and are arranged oppositely in a magnetic attraction mode. When the key cap is pressed by external force and moves to the pressing position, the protruding part pushes the two magnetic parts to be away from each other along the sliding way. When the key cap is released, the two magnetic parts get close along the sliding way due to the magnetic attraction force of the two magnetic parts, and the protruding part is pushed to drive the key cap to move back to the releasing position. The magnetic attraction force generated between the two magnetic parts serves as the driving force for resetting of the key cap, the structure of the key is simplified, and the service life is prolonged.

Description

technical field [0001] The present invention relates to a key and its keyboard, in particular to a key and its keyboard using magnetic attraction force as the driving force required for keycap reset. Background technique [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Not only that, but all consumer electronic products or large-scale processing equipment used in the industry need to be provided with a key structure as an input device to operate the above-mentioned electronic products and processing equipment. [0003] see figure 1 , which is a schematic cross-sectional view of the button 1 in the prior art. Such as figure 1 As shown, the button 1 includes a bottom plate 10 , a keycap 12 , a circuit board 14 , a supporting device 16 and an elastic member 18 . The circuit board 14 is disposed on the base plate 10 . The supporting device 16 is dispo...
