Abstract
The present invention relates to a stroke-limited key structure and a keyboard including the key. The key structure includes a base, a scissors-shaped member, and a cap. The scissors-shaped frame is disposed on the base, and the cap is disposed on the scissors-shaped member. The scissors-shaped frame includes a first frame and a second frame that is rotatably coupled to the first frame. The first and second frames include a first protrusion and a second protrusion. The stroke of the key is limited by using the engagement between the first and second protrusions.
Claims15
A key structure comprising:
- a base;
- a scissors-shaped member disposed on and connected with said base, said scissors-shaped member including a first frame and a second frame rotatably coupled to said first frame, said first frame including a first protrusion, and said second frame including a second protrusion;
- and
- a cap disposed on and connected with said scissors-shaped member;
- wherein said cap moves vertically relative to said base due to a relative rotation between said first frame and said second frame, said first protrusion engages with the second protrusion to stop said cap when said cap is elevated to a first position.
