Embodiment Construction

[0049]Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0050] An embodiment of the present disclosure provides a keyboard, which includes one or more keys. Please refer to figure 1 , which shows a schematic structural view of keys of a keyboard according to an exemplary embodiment. Such as figure 1 As shown, the key includes a keycap 101 , a keycap iron core 102 , a key base 103 and a rebound mechanism 104 .

Abstract

The embodiment of the invention discloses a keyboard, which comprises a keycap, a keycap iron core, a key holder, a springback mechanism and a control circuit, wherein the keycap is arranged on the keycap iron core, the key holder is provided with multiple turns of closed coils, and the keycap iron core is located in an area surrounded by the closed coils. The springback mechanism is used for enabling the pressed keycap to spring back to the original position. When the keycap is pressed, the keycap iron core goes deep into the area surrounded by the closed coils, induced current is generated in the closed coils, and the total current inside the closed coil is enabled to be reduced; and when the keycap springs back to the original position under the action of the springback mechanism, the keycap iron core moves upward and gradually breaks away from the closed coils, induced current is generated in the closed coils, and the total current in the closed coils is enabled to be increased. The operated key is recognized according to variation conditions of the current in the closed coils. The keycap and the key holder are not provided with a closed circuit therebetween, and the keycap and the key holder are not directly contacted, so that a pressure effect does not exist, the key is not worn, and thus the service life of the keyboard can be prolonged.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a keyboard and a key recognition method. Background technique [0002] The keyboard is the standard input device for computers. In the keyboard in the related art, a soft key is arranged under each key cap, and the soft key is equivalent to a switch. When the key cap is pressed, the soft key under the key cap will be close to the circuit in the keyboard to close the circuit. ; When the keycap bounces upwards, the soft key bounces upwards to disconnect the circuit in the keyboard. If the soft keys are used for a long time, there will be wear, aging and deformation, which will affect the sensitivity of the keyboard and reduce the service life of the keyboard. Contents of the invention [0003] In order to overcome the problems existing in the related technologies, the present disclosure provides a keyboard and a key recognition method. [0004] In order to solve the...
