Key structure

Abstract

A key structure includes a keycap, a base plate, and a connecting assembly. The connecting assembly includes a first connector, a second connector, and a resilient member. The first connector includes a limiting frame, a first side, and a second side. The limiting frame is disposed on the first side. The first side is connected to the keycap, and the second side is connected to the base plate. The second connector is pivotally connected to the first connector. The two opposite sides of the second connector are respectively connected to the keycap and the base plate. The resilient member includes a fixed end and a first spring arm. The fixed end is fixed to the first connector. One end of the first spring arm is connected to the fixed end, and the other end passes through the limiting frame.

Claims

1. A button structure, comprising: One-click cap; One base plate; And a connecting component, including: a first connector, including a limiting frame, a first side and a second side opposite to each other, the limiting frame being disposed on the first side, the first side being connected to the keycap, and the second side being connected to the base plate; a second connector, pivotally connected to the first connector, the two opposite sides of the second connector being connected to the keycap and the base plate respectively; and an elastic member, including a fixed end and a first spring arm, the fixed end being fixed to the first connector, one end of the first spring arm being connected to the fixed end, and the other end passing through the limiting frame.

2. The button structure as described in claim 1, wherein the other end of the first spring arm passes through the limiting frame and is located above the second connector or the base plate.

3. The key structure as described in claim 2, wherein the limiting frame includes a top side and a bottom side, and when the keycap is pressed, the first spring arm is interfered with by the second connector or the base plate, causing the first spring arm to abut against the top side of the limiting frame; when the second connector and the first spring arm do not interfere with each other, the first spring arm rebounds and contacts the bottom side of the limiting frame.

4. The button structure as described in claim 2, wherein the limiting frame includes a top side, a bottom side and a guide portion, the guide portion being located between the bottom side and the top side, and the width of the guide portion gradually increasing from the bottom side to the top side.

5. The key structure as described in claim 1, wherein the base plate further includes an interference structure that protrudes toward the keycap, and the other end of the first spring arm passes through the limiting frame and is located above the interference structure.

6. The button structure as described in claim 1, wherein the first connector further includes a fixed shaft, one side of which is connected to a side wall of the first connector, and the fixed end of the elastic member is sleeved on the fixed shaft.

7. The button structure as described in claim 6, wherein the fixed shaft includes a limiting portion located on the side of the fixed shaft away from the sidewall of the first connector, and the fixed end of the elastic member is located between the sidewall of the first connector and the limiting portion.

8. The button structure as described in claim 6, wherein the elastic element further includes a second spring arm, one end of which is connected to the fixed end, so that the elastic element forms a torsion spring structure.

9. The button structure as described in claim 8, wherein the second spring arm is closer to the sidewall of the first connector than the first spring arm.

10. The button structure as described in claim 1, wherein the first connector further includes a fixing part connected to one side wall of the first connector, the elastic member is a spring sheet, and the fixing end of the elastic member is connected to the fixing part.

11. The button structure as described in claim 1, wherein the first connector is an outer frame, the second connector is an inner frame, and the limiting frame and the elastic member are disposed on the side wall of the first connector facing the second connector.

12. The button structure as described in claim 1, wherein the first connector is an inner frame, the second connector is an outer frame, and the limiting frame and the elastic member are disposed on the side wall of the first connector facing the second connector.

13. The key structure as described in claim 1, wherein when the keycap is pressed, the first side of the first connector slides relative to the keycap.

14. The button structure as described in claim 1, wherein the elastic element is made of metal.
