A keyboard button and a keyboard with the keyboard button

Abstract

The invention discloses a keyboard key, which comprises a key cap and a contact block. The key cap includes a key cap cover, a key cap side wall and a key cap base. The keycap base and the keycap cover are respectively connected to opposite sides of the keycap side wall, a through hole is provided in the middle part of the keycap base, and the contact block is connected to one side of the keycap cover and is located at the gap formed by the keycap cover and the keycap side wall. In the cavity, the contact block protrudes from the through hole, the outer side wall of the keycap base is inclined inwardly along the positive pressure direction of the keyboard keys, and the outer side wall of the keycap base is inwardly aligned with the positive pressure direction of the keyboard keys. The included angle is twice the maximum offset angle of the key. When the keyboard key is subjected to side pressure, the distance between the outer side wall of the keycap base at the tilted end and the keyboard liner will not decrease as the keyboard key descends, thereby avoiding the The key stuck problem occurs due to the contact of the keyboard backing. The invention also discloses a keyboard with the keyboard keys.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a keyboard key and a keyboard with the keyboard key. Background technique [0002] In today's society where information flows rapidly, computers have become an indispensable tool for 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 based on the keyboard, and the keys on the keyboard are usually pressed repeatedly and frequently. How to increase the durability and operation time of the keys? The level of comfort has become the goal of research and development by major manufacturers. [0003] figure 1 3D exploded diagram of keyboard designed for traditional, such as figure 1 As shown, the keyboard includes a keyboard panel 201 , keyboard keys 204 , keyboard backing 202 , waterproof silicone 203 , binding l...

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
