Abstract
A key structure includes a base plate, a keycap and a connecting element. The connecting element includes a first frame and a second frame. The first frame is connected with the base plate and the keycap. The first frame includes a first linking part. The second frame is connected with the base plate and the keycap. The second frame includes a second linking part. The second linking part is contacted with the first linking part. When a depressing force from the user is applied to the keycap, the first frame is swung relative to the second frame. Moreover, in response to a friction between the first linking part and the second linking part, the keycap is correspondingly moved.

A key structure, comprising:
- a base plate;
- a keycap disposed over the base plate, wherein when a depressing force is received by the keycap, the keycap is moved relative to the base plate;
- and
- a connecting element arranged between the base plate and the keycap, wherein the base plate and the keycap are connected with each other through the connecting element, wherein as the connecting element is swung, the keycap is correspondingly moved relative to the base plate, wherein the connecting element comprises:
- a first frame located at a first side of the key structure, wherein a first end of the first frame is connected with the base plate, a second end of the first frame is connected with the keycap, the first frame comprises a first linking part, and the first linking part is formed on the second end of the first frame;
- and
- a second frame located at a second side of the key structure, wherein a first end of the second frame is connected with the base plate, a second end of the second frame is connected with the keycap, the second frame comprises a second linking part, and the second linking part is formed on the second end of the second frame and contacted with the first linking part, wherein when the depressing force is received by the keycap, the first frame is swung relative to the second frame, and the keycap is correspondingly moved in response to a friction between the first linking part and the second linking part;
- wherein the first frame further comprises a first coupling part formed on the second end of the first frame, wherein the first coupling part is connected with a first bulge of the keycap, and the first coupling part is rotatable relative to the first bulge, wherein the first linking part is formed on an outer surface of the first coupling part;
- and wherein the second frame further comprises a second coupling part formed on the second end of the second frame, wherein the second coupling part is connected with a second bulge of the keycap, and the second coupling part is rotatable relative to the second bulge, wherein the second linking part is formed on an outer surface of the second coupling part.
A key structure, comprising:
- a base plate;
- a keycap disposed over the base plate, wherein when a depressing force is received by the keycap, the keycap is moved relative to the base plate, wherein the keycap comprises a first linking part, and the first linking part is disposed on a bottom surface of the keycap;
- and
- a connecting element arranged between the base plate and the keycap, wherein the base plate and the keycap are connected with each other through the connecting element, wherein as the connecting element is swung, the keycap is correspondingly moved relative to the base plate, wherein the connecting element comprises at least one frame, the at least one frame is located at a side of the key structure, a first end of the at least one frame is connected with the base plate, a second end of the at least one frame is connected with the keycap, the at least one frame comprises a second linking part, and the second linking part is formed on the second end of the at least one frame and contacted with the first linking part, wherein when the depressing force is received by the keycap, the second linking part is rotated with the first linking part and the at least one frame is swung, so that the keycap is correspondingly moved.
