Key and keyboard thereof

Abstract

The invention relates to a key which comprises a bottom plate, a keycap, a first supporting part and a second supporting part. The keycap is provided with a clamping groove provided with rotating space and a clamping opening. The first supporting part is provided with a first pivotal connection shaft connected into the clamping groove in a pivotal mode, and a first combination mechanism movably connected to the bottom plate. The second supporting part and the first supporting part intersect and are connected in a pivotal mode. When the first pivotal connection shaft is passing through the clamping groove opening, the first pivotal connection shaft is extruded through the clamping groove so that a groove of the first pivotal connection shaft can be deformed, and the first pivotal connection shaft can have the first dimension. When the first pivotal connection shaft has passed through the clamping groove opening and enters the rotating space, deformation of the groove is reduced so that the first pivotal connection shaft can have the second dimension. The second dimension is larger than the first dimension and the clamping groove opening gap of the clamping groove opening so that the first pivotal connection shaft can be restrained in the clamping groove. The key solves the problems that the keycap is uneasy to install and supporting parts can be damaged easily in the process of assembling in the prior art.

Description

technical field [0001] The present invention relates to a key and its keyboard, in particular to a key and its keyboard with a groove formed on the pivot shaft of the supporting member. 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 in daily life or large-scale processing equipment used in the industry need to be equipped 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 key 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 bottom board 10 , and the supporting device 16 and ...

AI Technical Summary

Problems solved by technology

However, the above method tends to cause excessive assembly resistance between the first pivot shaft 25 and the first slot 13 when the key cap 12 is assembled with the support device 16, which makes it difficult to install the key cap 12 and the first slot 13 Problems that are prone to damage during assembly

[0005] Although the above problems can be solved by increasing the distance between the openings 31, this will reduce the pull-out force between the keycap 12 and the supporting device 16, causing the keycap 12 to easily fall off from the supporting device 16.
