Keypress and keyboard with same

Abstract

The invention discloses a keypress, comprising a key cap and a contact piece, wherein, the key cap comprises a key cap cover, a key cap sidewall and a key cap base; the key cap base and the key cap cover are separately connected with the corresponding two sides of the key cap sidewall, a through-hole is arranged in the middle of the key cap base, the contact piece is connected with one side face of the key cap cover and arranged in a cavity which is formed by the key cap cover and the side face of the key cap, the contact piece is penetrated through the through-hole and the outer sidewall of the key cap base is inclined inwardly along the positive pressure direction of the keypress. When keypress undertakes a lateral pressure, the distance between the outer sidewall of the key cap base on the raised end and a lining board of the keyboard can not be reduced when the keypress declines, thus avoiding the problem that the keypress is blocked owning to the contact between the side wall of the key cap base and the lining board of the keyboard. The invention also provides a keyboard with the keypress.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a keyboard key and a keyboard having the keyboard key. Background technique [0002] In today's society with rapid information flow, computers have become an indispensable tool in various industries. The types and styles of computers are also changing with each passing day as their functions increase. However, no matter what kind of computer it is, the interface it has to communicate with the user is still the keyboard, and the keys on the keyboard are usually pressed repeatedly and frequently. How to increase the durability of the keys and the operation time? The comfort level has become the goal of research and development by major manufacturers. [0003] figure 1 3D exploded schematic diagram for a traditionally designed keyboard, such as figure 1 As shown, the keyboard includes a keyboard panel 201 , keyboard keys 204 , a keyboard backing plate 202 , waterproof silicone 203 , a...

AI Technical Summary

Problems solved by technology

When the keyboard key 204 moves downward around the corresponding rotation center after being stressed, the distance d2 between the keyboard backing plate 202 and the keyboard key 204 becomes smaller as the keyboard key 204 is pressed down, and the waterproof silicone 203 produces an impact on the keyboard key 204 Rebound resistance, when the side is pressed, as the distance d2 between the keyboard liner 202 and the keyboard keys 204 decreases, the keyboard keys 204 will get stuck and cannot be pressed down

In addition, because there are processing errors between the keyboard panel 201 and the keyboard backing plate 202 and there are certain errors during assembly, the situation of stuck keys will be more serious.

In order to avoid stuck keys, the traditional design only enlarges the distance d1 between the keyboard panel 201 and the keyboard keys 204 and the distance d2 between the keyboard backing plate 202 and the keyboard keys 204 on the basis of the normal value, which will cause the keyboard keys 204 to become loose and at the same time Unresponsiveness when side pressure occurs

[0008] 2. Analysis of dust prevention problems

[0009] like Figure 2a-2b As shown, no matter whether the keyboard is in the working state or the non-working state, dust can enter through the distance d1 between the keyboard panel 201 and the keyboard keys 204, and accumulate in the gap between the keyboard backing plate 202 and the keyboard keys 204, as shown in the figure As shown by the dotted line, when dust accumulates on the A side or B side of the key, press the side pressure direction, as shown by the arrow a, or the positive pressure direction, that is, the direction perpendicular to the key surface, as shown by the arrow e. When the keyboard is pressed 204 times, there may be phenomena such as key stuck and key failure, which shortens the normal service life of the keyboard
