Magnetic attraction keyboard and key thereof

Abstract

The invention provides a magnetic-absorbing keyboard and its keys, which include a keycap, a bottom plate, a thin-film circuit, a frame, a first magnetic-absorbing part, a second magnetic-absorbing part and a third magnetic-absorbing part. Among them, the keycap is used to provide the pressing operation; the thin film circuit is arranged on the bottom plate; the frame is arranged on the bottom plate and the thin film circuit, and has a first concave portion, a second concave portion and an opening, and the keycap is movable through the opening, and the frame also There is an accommodating space; the first magnetic attraction is arranged on the bottom plate and is located in the first recess; the second magnetic attraction is arranged on the bottom plate and is located in the second recess; the third magnetic attraction is arranged under the keycap and is located in the accommodation space. A first magnetic attraction force and a second magnetic attraction force are respectively formed between the third magnetic attraction part and the first magnetic attraction part and between the third magnetic attraction part and the second magnetic attraction part, so as to drive the keycap to protrude from the opening. The present invention resets the key caps by means of the lateral or horizontal magnetic suction force, which can reduce the thickness and volume of the keys and facilitate thinning production.

Description

technical field [0001] The present invention relates to a keyboard and its keys, and in particular to a magnetic suction keyboard and its keys. Background technique [0002] Modern people often use computers in their daily life, and whether it is a desktop computer (or personal computer (PC)) or a notebook computer, the keyboard plays an important role in providing users with character input or operation control. Generally speaking, a keyboard is composed of many keys, and each key is arranged at a specific position. In addition, many electronic devices or motor-operated devices are also provided with related buttons, which are used as operation interfaces for various specified functions. [0003] In order to provide users with input and control, the application characteristic of this aspect of the button is that it can be designed to return to its original position after a one-time press, and at the same time, a trigger signal can be generated in response to the press.

Problems solved by technology

Therefore, for the above-mentioned type of magnetic keyboard keys, it is designed to superimpose the magnet on the outer edge of the keycap and the magnet on the keyboard frame in the pressing direction of the keycap, plus the necessary pressing buffer space, As a result, the thickness and volume of the overall key structure will be relatively large, which will limit the requirements for thinning the keyboard or electronic devices.
