Abstract
Claims
1. A button structure, comprising: Keycaps have a prominent structure; A bottom fixing component is located below the keycap; A lifting assembly is connected between the keycap and the bottom fixing member and is adapted to move along the lifting direction; and a spring assembly is disposed on the bottom fixing member and includes opposing first electrical contact and second electrical contact, wherein when the keycap approaches the bottom fixing member along the lifting direction, the protruding structure pushes the spring assembly so that the first electrical contact contacts or moves away from the second electrical contact.
2. The key structure as claimed in claim 1, wherein the protruding structure includes a cylindrical body and a protrusion extending from the lower surface of the keycap, the protrusion being adapted to contact the spring assembly.
3. The button structure as claimed in claim 2, wherein the lifting assembly includes an elastic element disposed between the keycap and the bottom fixing member, and at least a portion of the elastic element is received in an accommodating space within the cylinder.
4. The button structure as claimed in claim 2, wherein the protrusion has a bevel adapted to contact and push the spring assembly.
5. The button structure as described in claim 4, wherein the cylinder and the protrusion are connected to each other, and the inclined surface faces away from the cylinder.
6. The button structure as claimed in claim 4, wherein the cylinder and the protrusion are separate from each other, and the inclined surface faces the cylinder.
7. The button structure as described in claim 2, wherein the spring assembly further includes a first spring and a second spring, the first spring and the second spring respectively having a first electrical contact portion and a second electrical contact portion, and the first spring having a notch corresponding to the protrusion.
8. The key structure as described in claim 2, wherein when the keycap approaches the bottom fixing member along the lifting direction, the protrusion pushes the first electrical contact away from the second electrical contact along the moving direction; when the keycap moves away from the bottom fixing member along the lifting direction, the protrusion moves away from the first electrical contact, the first electrical contact resets and contacts the second electrical contact, and the moving direction is perpendicular to the lifting direction.
9. The key structure as described in claim 2, wherein when the keycap approaches the bottom fixing member along the lifting direction, the protrusion pushes the first electrical contact to approach and contact the second electrical contact along the moving direction; when the keycap moves away from the bottom fixing member along the lifting direction, the protrusion moves away from the first electrical contact, the first electrical contact is reset and separates from the second electrical contact, and the moving direction is perpendicular to the lifting direction.
10. The key structure as claimed in claim 2, wherein the first electrical contact portion at least partially overlaps the second electrical contact portion in the lifting direction, and when the keycap approaches the bottom fixing member in the lifting direction, the protrusion pushes the first electrical contact portion to approach and contact the second electrical contact portion in the lifting direction.
