Abstract

An electronic device includes a main body, a cover, and two support legs. The main body defines two receiving portions. The cover is rotatably connected to the main body. Two resisting portions are formed on the cover. The support legs are rotatably received in the receiving portions of the main body respectively. When the cover rotates relative to the main body, the resisting portions resist the support legs to rotate, thus driving the support legs protruding out from the main body.

Claims

1. An electronic device, comprising:

a main body defining at least one receiving portion, the at least one receiving portion comprising two opposite first sidewalls;

at least one connecting shaft connected to the first sidewalls;

a cover rotatably connected to the main body, wherein at least one resisting portion is formed on the cover;

at least one support leg rotatably received in the at least one receiving portion of the main body via the at least one connecting shaft;

a positioning pole formed on the main body; and

an elastic member sleeved on the positioning pole and compressed between the support leg and the main body;

wherein when the cover rotates relative to the main body, the at least one resisting portion causes the at least one support leg to rotate and protrude out from the main body.

2. The electronic device of claim 1, wherein a fixing piece is formed on each first sidewall;

the at least one connecting shaft is fixedly connected to the fixing piece.

3. The electronic device of claim 2, wherein the positioning pole is formed on the first sidewall.

4. The electronic device of claim 3, wherein the elastic member is a torsion spring.

5. The electronic device of claim 4, wherein the at least one receiving portion further comprises a second sidewall connecting with the first sidewalls, a first positioning hook is formed on the second sidewall;

a second positioning hook is formed on the at least one support leg;

one end of the elastic member engages with the first positioning hook, the other end of the elastic member engages with the second positioning hook.

6. The electronic device of claim 1, wherein the at least one support leg comprises two support legs;

the at least one resisting portion comprises two resisting portions;

when the cover rotates relative to the main body, the resisting portions resist the support legs respectively.

7. The electronic device of claim 6, wherein the at least one receiving portion comprises two receiving portions;

the support legs are received in the receiving portions respectively.

8. The electronic device of claim 1, wherein the at least one support leg comprises a support portion and a contacting portion aslant extending from an end of the support portion.

9. The electronic device of claim 1, further comprising at least one pivot shaft;

the main body comprises an assembling portion;

the at least one pivot shaft extends through the at least one resisting portion of the cover, and engages in the assembling portion, to rotatably connect the cover to the main body.

10. The electronic device of claim 1, wherein the electronic device is a notebook computer.

11. An electronic device, comprising:

a main body defining at least one receiving portion, the at least one receiving portion comprising two opposite first sidewalls;

at least one connecting shaft connected to the first sidewalls;

a cover rotatably connected to the main body, wherein a resisting portion is formed on the cover;

a support leg rotatably connected to the main body via the at least one connecting shaft, wherein the support leg is received in the main body;

a positioning pole formed on the main body; and

an elastic member sleeved on the positioning pole and compressed between the support leg and the main body;

wherein when the cover is rotated relative to the main body, the resisting portion causes the support leg to rotate, so that the main body is supported by the support leg.

12. The electronic device of claim 11, wherein the support leg comprises a support portion and a contacting portion slantingly extending from an end of the support portion.

13. The electronic device of claim 11, further comprising a pivot shaft;

the main body comprises an assembling portion;

the cover comprises a resisting portion;

the pivot shaft extends through the resisting portion of the cover, and engages in the assembling portion, to rotatably connect the cover to the main body.

14. The electronic device of claim 11, wherein the electronic device is a notebook computer.
