Abstract
A key structure includes a base plate, a keycap, a scissors-type connecting member, and an elastic element. The scissors-type connecting member is connected with the base plate and the keycap. After the key structure is assembled and the keycap is not assembled, the elastic element provides an upward first elastic force, and the scissors-type connecting member is bent to provide a downward second elastic force. By exerting a small force on the keycap, the key structure can be triggered.
Claims13
A key structure with a scissors-type connecting member, the key structure comprising:
- a base plate;
- a keycap disposed over the base, wherein when the keycap is depressed, the keycap is moved relative to the base plate;
- the scissors-type connecting member arranged between the base plate and the keycap for connecting the base plate with the keycap, thereby allowing the keycap to be moved upwardly or upwardly respective to the base plate;
- and
- an elastic element arranged between the base plate and the keycap and penetrated through the scissors-type connecting member, wherein the elastic element is contacted with the keycap and provides an elastic force to the keycap, wherein when the keycap is not depressed, the scissors-type connecting member is bent.
A key structure with a scissors-type connecting member, the key structure comprising:
- a base plate;
- a keycap disposed over the base, wherein when the keycap is depressed, the keycap is moved relative to the base plate;
- the scissors-type connecting member arranged between the base plate and the keycap for connecting the base plate with the keycap, thereby allowing the keycap to be moved upwardly or upwardly respective to the base plate, wherein the scissors-type connecting member comprises:
- a first frame comprising a first sidewall, wherein a first end of the first sidewall is connected with the keycap, and a second end of the first sidewall is connected with the base plate;
- and
- a second frame pivotally coupled to the first frame, wherein the second frame is rotatable relative to the first frame by using a pivotal point between the first frame and the second frame as a rotating shaft, wherein the second frame comprises a second sidewall, a first end of the second sidewall is connected with the base plate, and a second end of the second sidewall is connected with the keycap;
- and
- an elastic element arranged between the base plate and the keycap and penetrated through the scissors-type connecting member, wherein the elastic element is contacted with the keycap and provides an elastic force to the keycap,
- wherein the first end of the first sidewall is thinner than the second end of the first sidewall, and the first end of the second sidewall is thicker than the second end of the first sidewall.
