Abstract

A hinge structure is described. A hollow cylinder has a positioning slot in an inner wall thereof. A movable part has a positioning convex portion and a plurality of engraved portions. The positioning convex portion engages with the positioning slot such that the movable part slides within the hollow cylinder. A cover is fixed to the hollow cylinder to secure the movable part and the resilient part within the hollow cylinder. A resilient part is disposed between the cover and the movable part so as to provide the movable part a resilient recovery force. The engraved portions of the movable part are for engaging a rotatable member.

Claims

1. A hinge, comprising:

a hollow cylinder, having a positioning slot in an inner wall thereof;

a movable part, having a positioning convex portion and a plurality of engraved portions, wherein the positioning convex portion engages with the positioning slot such that the movable part slides within the hollow cylinder, the engraved portions are radially arranged on the movable part;

a resilient part, disposed within the hollow cylinder; and

a cover, fixed to the hollow cylinder to secure the movable part and the resilient part within the hollow cylinder, the resilient part being disposed between the cover and the movable part so as to provide the movable part a resilient recovery force, the engraved portions of the movable part are for engaging a rotatable member.

2. The hinge module of claim 1, wherein the movable part, the resilient part and the cover all have a hole, and all the holes are aligned.

3. The hinge module of claim 1, wherein the movable part is a disk-shaped movable part.

4. A device having a hinge module, comprising:

a stationary member;

a rotatable member, having a bar; and

a hinge module interconnecting the stationary member and the rotatable member such that the rotatable member rotates relative to the stationary member, wherein the hinge module comprising;

a hollow cylinder, having a positioning slot in an inner wall thereof;

a movable part, having a positioning convex portion and a plurality of engraved portions, wherein the positioning convex portion engages with the positioning slot such that the movable part slides within the hollow cylinder, the engraved portions are radially arranged on the movable part;

a resilient part, disposed within the hollow cylinder; and

a cover, fixed to the hollow cylinder to secure the movable part and the resilient part within the hollow cylinder, the resilient part being disposed between the cover and the movable part so as to provide the movable part a resilient recovery force, the bar of the rotatable member engaging with one of the engraved portions of the movable part.

5. The device of claim 4, wherein the movable part, the resilient part and the cover all have a hole, and all the holes are aligned.

6. The device of claim 5, wherein the rotatable member comprises a screw hole.

7. The device of claim 6, wherein the stationary member comprises an opening.

8. The device of claim 7, further comprising a screw to be led through the opening of the stationary member and the aligned holes of the hinge module, and secured into the screw hole of the rotatable member.

9. The device of claim 8, wherein the stationary member comprises a circular concave section for accommodating the hinge module, and the opening is disposed in the circular concave section.

10. The device of claim 8, further comprising a washer disposed between the screw and the stationary member.

11. The device of claim 10, wherein the stationary member comprises another circular concave section where the washer is disposed within.

12. The device of claim 5, wherein the rotatable member comprises a connection interface having a plurality of input and output ports.
