Abstract

An electronic device includes a first body, a second body, two hinge assemblies, two resilient members, and two latching members. The hinge assemblies hinge the first body on the second body. The resilient members are received in the second body and connect with the second body elastically. Opposite ends of the resilient member resist the second body and the hinge assembly, so that the hinge assembly and the first body move relative to the second body.

Claims

1. An electronic device, comprising:

a first body comprising a first connecting portion and a second connecting portion;

a second body connecting to the first body;

a hinge assembly hinging the first body on the second body, the hinge assembly comprising a sleeve connected to the first body, wherein the sleeve comprises a receiving portion, and the second body defines a mounting slot receiving the receiving portion, the first connecting portion and the second connecting portion received in the mounting slot; and

the receiving portion of the sleeve being positioned between the first connecting portion and the second connecting portion; and

a resilient member received in the second body, sliding the hinge assembly and the first body a predetermined distance relative to the second body.

2. The electronic device of claim 1, wherein the sleeve further comprises a guiding portion extending from the receiving portion;

the second body forms a receiving chamber communicating with the mounting slot; and

the guiding portion is received in the receiving chamber.

3. The electronic device of claim 2, wherein the guiding portion defines a guiding hole in which the resilient member is received and resists the receiving chamber of the second body.

4. The electronic device of claim 1, wherein the hinge assembly further comprises a shaft extending through the first connecting portion, the receiving portion of the sleeve, and the second connecting portion.

5. The electronic device of claim 4, wherein the first body further defines a positioning slot;

and the hinge assembly further comprises a fastener forming a positioning protrusion engaging in the positioning slot.

6. The electronic device of claim 5, wherein the hinge assembly further comprises a friction member sleeved in the shaft and received in the receiving portion of the sleeve.

7. The electronic device of claim 1, wherein the first body comprises a first surface and a hook formed on the first surface and engaged by a latching member.

8. The electronic device of claim 7, wherein the second body comprises a locking slot comprising an entrance and a locking portion into which the hook enters through the entrance to be locked by the locking portion.

9. The electronic device of claim 8, wherein the second body defines a receiving slot communicating with the locking slot;

and the latching member comprises a latching portion and a resilient portion resisting the latching portion.

10. The electronic device of claim 9, wherein the latching member further comprises a resisting hook engaging with the hook of the first body.

11. The electronic device of claim 1, wherein the resilient member is a helical compression spring.

12. An electronic device, comprising:

a first body comprising a first connecting portion and a second connecting portion;

a second body connecting to the first body;

a hinge assembly hinging the first body on the second body, the hinge assembly comprising a sleeve connected to the first body, wherein the sleeve comprises a receiving portion, and the second body defines a mounting slot receiving the receiving portion, the first connecting portion and the second connecting portion received in the mounting slot; and

the receiving portion of the sleeve being positioned between the first connecting portion and the second connecting portion; and

a resilient member elastically positioned between the first body and the second body, sliding the first body relative to the second body.

13. The electronic device of claim 12, wherein the hinge assembly further comprises a shaft extending through the first connecting portion, the receiving portion of the sleeve, and the second connecting portion.

14. The electronic device of claim 13, wherein the first body further defines a positioning slot;

and the hinge assembly further comprises a fastener, the fastener forming a positioning protrusion engaging in the positioning slot.
