Description

Key switch and keyboard

Technical Field

The utility model belongs to the technical field of computer input equipment, and particularly relates to a key switch and a keyboard.

Background

With the increase of computer users, the users of computer keyboards also increase, and higher demands are gradually put on the use experience of the keyboards. For electronic contestants, game febrile friends and professional word workers, the hand feeling of the keys is a very important consideration, for example, a key switch (also called an axis) of a mechanical keyboard can be divided into a green axis, a tea axis, a linear axis and the like, and the corresponding hand feeling of each axis is inconsistent due to different structures. The green shaft can generate obvious paragraph sense in the pressing process and is accompanied with knocking sound; the tea shaft has friction force in the pressing process, can generate friction hand feeling, but has no knocking sound; the linear axis produces a "linear" feel because there is no obstruction in the pressing down of the handle.

The hand feeling of the key switch is determined by the structure of the switch, and once the structure is fixed, the corresponding hand feeling cannot be changed, so that how to meet the DIY requirement of a user is a problem to be solved urgently. The prior art provides a push-button switch comprising a torsion spring, wherein the position of the torsion spring is changed by adopting a sliding switching piece and a spring part limiting block, and the switching between sound and silence and between linear handfeel and paragraph handfeel is realized according to whether the torsion spring knocks a base or not and the knocking time. This prior art, while addressing some of the DIY needs of the user, also has the drawback of being apparent: firstly, more components are required to be arranged in the key switch, so that the structure of the switch is complex, the production and assembly cost is increased, and the torsion spring is easy to deform after long-time use, so that the hand feeling is not switched accurately; secondly, the hand feeling and the sound producing effect of the device depend on the torsion spring, the design requirements on the material and the shape of the device are higher, and the sound producing effect of the torsion spring as a knocking element is thinner; finally, the hand-feel switching technology realized by changing the internal structure of the switch causes that the hand-feel switching technology can only be adjusted one by one, and the requirement of simultaneously adjusting a plurality of switches, even all switches of the keyboard, cannot be met.

Referring to fig. 1 and 2, a key switch 100 and a keyboard according to the present utility model will now be described. The key switch 100 includes a housing 10, a pressing handle 20 and an adjusting mechanism 30, where the pressing handle 20 is disposed in the housing 10 and can move up and down relative to the housing 10, the pressing handle 20 is provided with an impact portion 21, the adjusting mechanism 30 is movably disposed in the housing 10, and the position relationship between the adjusting mechanism 30 and the housing 10 is variable, i.e., at least two relative positions between the adjusting mechanism 30 and the housing 10 can be changed by moving the adjusting mechanism 30 or the housing 10, and the moving mode can cover sliding or rotating, so long as the switching of the position relationship between the adjusting mechanism 30 and the housing 10 can be realized. When the shell 10 and the adjusting mechanism 30 are in a first relative position, the striking part 21 moves downwards along with the pressing handle 20 and can strike the adjusting mechanism 30, when the shell 10 and the adjusting mechanism 30 are in a second relative position, the striking part 21 moves downwards along with the pressing handle 20 but can not strike the adjusting mechanism 30, that is, the adjusting mechanism 30 or the shell 10 is moved, when the shell 10 and the adjusting mechanism 30 are in the first relative position, the pressing handle 20 is pressed, the pressing handle 20 moves downwards, the striking part 21 on the pressing handle 20 also moves downwards along with the pressing handle 20, and at the moment, the striking part 21 can strike the adjusting mechanism 30 when moving downwards, so that the key switch 100 can generate striking sound; when the housing 10 and the adjusting mechanism 30 are in the second relative positional relationship, the pressing handle 20 is pressed, the striking portion 21 on the pressing handle 20 moves smoothly downward along with the pressing handle 20, the adjusting mechanism 30 is not struck in the whole stroke, at this time, the push switch 100 does not generate striking sound, that is, the downward moving stroke of the pressing handle 20 can be adjusted by changing the relative positional relationship between the adjusting mechanism 30 and the housing 10, the using feel of a user is improved, meanwhile, the sounding and silencing functions of the push switch 100 can be adjusted, namely, the pressing handle 20 moves in a sounding mode when moving in a short stroke, and moves in a silencing mode when moving in a long stroke, so that two different requirements of the push switch 100 for sounding and silencing can be met in different using scenes of the user are met, and the convenience of switching the two modes of the user is improved due to the structural arrangement of the push switch 100. It should be noted that, the key switch 100 in the present utility model may be a mechanical switch, an optoelectronic switch, a magnetic induction switch, an electric induction switch, etc., and the type of the key switch 100 is not limited.

Compared with the prior art, the key switch 100 provided by the utility model further comprises the adjusting mechanism 30, the position relation between the adjusting mechanism 30 and the shell 10 is variable, and the relative position relation between the adjusting mechanism 30 and the shell 10 can be changed after the shell 10 or the adjusting mechanism 30 is moved. When the shell 10 and the regulating mechanism 30 are in a first relative position relation, the impact part 21 can impact the regulating mechanism 30 in the downward movement stroke of the handle 20, and the impact can also generate impact sound, so that the short-stroke hand feeling is realized and the sound can be generated; when the housing 10 and the adjusting mechanism 30 are in the second relative positional relationship, the striking portion 21 cannot strike the adjusting mechanism 30 in the entire stroke of the downward movement of the pressing handle 20, thereby realizing a long-stroke feeling and a mute effect. That is, by changing the relative positional relationship between the adjusting mechanism 30 and the housing 10, the downward movement stroke of the push button 20 can be adjusted to improve the user's hand feeling, and the sounding and silencing functions of the push button switch 100 can be adjusted, that is, the sounding mode when the push button 20 moves for a short stroke and the silencing mode when the push button 20 moves for a long stroke, so as to meet two different requirements of the user on the sounding and silencing of the push button switch 100 in different use scenarios.
