keyboard

Abstract

The invention provides a keyboard. The keyboard comprises a first bottom plate, a second bottom plate and keys, wherein the second bottom plate is glidingly arranged on the first bottom plate and forms a convex bending arm; the keys are arranged on the first bottom plate, comprising key caps, lifting supporting devices, teeterboard components, and magnetic conductive material blocks arranged on the first bottom plate; the lifting supporting devices are connected between the key caps and the first bottom plate and enable the key caps to move up and down; each teeterboard component is equipped with a pivoting arm part, a magnetic conductive material arm part and a supporting propping part, wherein each pivoting arm part is pivoted to each key cap; ach supporting propping part is glidingly arranged on each magnetic conductive material block; each magnetic conductive material arm part is propped to the convex bending arm; when the two bottom plates slide opposite to each other, the convex bending arm pushes the magnetic conductive material arms to tilt to enable the caps to move downwards, or the magnetic conductive material arms are absorbed to the magnetic conductive material blocks to enable the pivoting arm parts to push the key caps to move upwards; therefore, the keyboard can be closed to enter the state that the height of the key caps is reduced, and as a result, the overall height of the keyboard can be further reduced.

Description

technical field [0001] The present invention relates to a keyboard, in particular to a design in which a seesaw member abuts against a protruding bent arm on the bottom plate and is detachably adsorbed on a block of magnetically permeable material so that the keycap can follow the relative movement between the bottom plates. Swipe to move the keyboard up and down. Background technique [0002] As far as the current usage habits of notebook computers are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Recently, due to the thinning trend of notebook computers, there is also a demand for thinner keyboards used in notebook computers. [0003] The conventional key is often provided with an elastic element, such as a rubber washer (Rubber Dome), etc., to serve as a source of elastic force for the keycap to reset when the key is used. However, the known elastic element has a specific height, so when the top cover and...

AI Technical Summary

Problems solved by technology

However, the known elastic element has a specific height, so when the top cover and the bottom casing of the notebook computer are folded, in order to prevent the keycaps on the bottom casing from damaging the display screen on the top cover, the upper There is always a clearance between the cover and the lower case

In other words, because the conventional button is provided with an elastic element, it will limit the appearance and size design of the notebook computer, which is not conducive to the thinning trend of the notebook computer.
