Keyboard and key thereof

Abstract

The invention provides a keyboard and a key thereof. The key comprises a key cap, a pedestal, a film circuit board, a first part, a first spring and a second spring, and the first part comprises a contact portion; a first end of the first spring abuts against the key cap, a second end of the first spring abuts against the first part, the second spring sleeves the contact portion, a third end of the second spring abuts against the first part and a fourth end of the second spring abuts against the pedestal; when the key cap moves from an initial position to the pedestal along a first direction, the key cap drives the first part to move towards the pedestal and the first part to press the second spring till the key cap moves to a first position and the contact portion presses the film circuit board; and when the key cap continues to move from the first position to the pedestal along the first direction, the key cap presses the first spring and the first spring is compressed till the key cap moves to a second position, and in the process that the key cap moves from the first position to the second position, the contact portion continues to press the film circuit board. The keyboard and the key thereof are low in the cost, and solve the problems that the hand feeling is not good and the precision is low.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to a keyboard key comprising two springs and a keyboard using the keyboard key. Background technique [0002] Along with the rising of people to the requirement of daily necessities, people are also more and more higher to the requirement of computer keyboard commonly used when particularly operating computer. [0003] figure 1 It is a sectional view of a keyboard key in the prior art when it is in a free state, such as figure 1 As shown, the keyboard key 200 includes a keycap 201, a rubber dome 202, a film circuit board 203 and a base 204, wherein the rubber dome 202 is used to support the keycap and provide elastic recovery when the user presses the keycap 201 force. The rubber dome 202 is usually made of silicon rubber (Silicon Rubber) injection molded as a whole piece or the silicon rubber is pasted on the plastic through a multi-cavity process. However, the cost of silico...

AI Technical Summary

Problems solved by technology

However, the cost of silicone rubber is high, and the corners of the silicone dome 202 manufactured by the process of one mold with multiple holes or the corners of the whole piece are different from the center material, resulting in a deviation in hand feeling. In addition, the adhesion accuracy can only be controlled at plus / minus 0.3 mm (millimeter) leads to low precision, and after the thin film circuit board is turned on, there is no key stroke or the key stroke is too short, resulting in poor hand feeling
