Abstract

A hinge assembly includes a shaft, a fixing bracket, a revolving bracket, a resilient member, and a fastening member. The fixing bracket comprises a contact surface, and is sleeved on the shaft. The revolving bracket comprises a contact surface matching the contact surface of the fixing bracket. The resilient member is sleeved on the shaft. The fastening member is fixed on the shaft. The contact surface of the fixing bracket defines at least two positioning recesses, in one of which a positioning protrusion formed on the contact surface of the revolving bracket is selectively received.

Claims

1. A hinge assembly comprising:

a pivot shaft;

a fixing bracket comprising a contact surface, and sleeved on the pivot shaft;

a revolving bracket comprising a contact surface matching the contact surface of the fixing bracket, the revolving bracket sleeved on the pivot shaft;

a resilient member sleeved on the pivot shaft; and

a fastening member fixed on the pivot shaft;

wherein the contact surface of the fixing bracket defines at least two positioning recesses, and the contact surface of the revolving bracket forms a positioning protrusion selectively received in one of the positioning recesses.

2. The hinge assembly of claim 1, wherein the fixing bracket further defines a pivot hole, a center of the pivot hole shares a circumference at which the positioning recesses are aligned.

3. The hinge assembly of claim 1, wherein the positioning recess is arcuate, and the positioning protrusion corresponds in shape to and is smaller than the positioning recess.

4. The hinge assembly of claim 1, wherein the fixing bracket further comprises a restricting protrusion protruding out of the contact surface, the revolving bracket defines a curved restricting slot in the contact surface, and the restricting protrusion is received in the curved restricting slot.

5. The hinge assembly of claim 1, wherein the revolving bracket comprises a rotary portion and a swing arm extending therefrom, wherein the rotary portion defines a through hole through which the pivot shaft passes.

6. The hinge assembly of claim 5, further comprising a protective member defining a receiving slot in which the swing arm is securely received.

7. The hinge assembly of claim 6, wherein the protective member comprises a main body and an engaging portion at an end of the main body, the receiving slot defined in the main body, and the engaging portion formed at an end of the main body away from the rotary portion.

8. The hinge assembly of claim 7, wherein the engaging portion is a silicone gasket.

9. The hinge assembly of claim 1, wherein the revolving bracket and the fixing bracket are the same materials.

10. The hinge assembly of claim 1, further comprising a washer positioned between the resilient member and the fastening member.

11. A hinge assembly comprising:

a shaft;

a fixing bracket comprising a contact surface, and sleeved on the shaft;

a revolving bracket comprising a contact surface matching with the contact surface of the fixing bracket, the revolving bracket sleeved on the shaft;

a resilient member sleeved on the shaft; and

a fastening member fixed on the shaft;

wherein the contact surface of the revolving bracket defines at least two positioning recesses, and the contact surface of the fixing bracket forms a positioning protrusion selectively engaging with one of the positioning recesses.

12. The hinge assembly of claim 11, wherein the revolving bracket further defines a through hole, a center of the through hole shares a circumference at which the positioning recesses are aligned.

13. The hinge assembly of claim 11, wherein the positioning recess is arcuate, and the positioning protrusion corresponding in shape to and smaller than the positioning recess.

14. The hinge assembly of claim 11, wherein the fixing bracket further comprises a restricting protrusion protruding out of the contact surface, and the revolving bracket defines a curved restricting slot in the contact surface in which the restricting protrusion is received.

15. The hinge assembly of claim 11, wherein the revolving bracket comprises a rotary portion and a swing arm extending from the rotary portion, the rotary portion defining a through hole through which the shaft passes.

16. The hinge assembly of claim 15, further comprising a protective member defining a receiving slot in which the swing arm is securely received.

17. The hinge assembly of claim 16, wherein the protective member comprises a main body and an engaging portion at an end of the main body, wherein the receiving slot is defined in the main body and the engaging portion is formed at an end of the main body away from the rotary portion.

18. The hinge assembly of claim 17, wherein the engaging portion is a silicone gasket.

19. The hinge assembly of claim 11, wherein the revolving bracket and the fixing bracket are the same materials.

20. The hinge assembly of claim 11, further comprising a washer positioned between the resilient member and the fastening member.
