Abstract

An exemplary electronic device (30) includes a main body (40) and two supporting mechanisms (60). The supporting mechanisms are formed at two adjacent corners of the main body respectively. Each supporting mechanism includes a support leg (62), a positioning leg (64), and an elastic member (65). The support leg is rotatably connected to the main body, and configured for supporting the main body. The positioning leg is rotatably connected to the support leg, and configured for supporting the support leg. The elastic member is resisted between the support leg and the positioning leg, thus producing an elastic force to drive the positioning leg away from the support leg.

Claims

1. An electronic device, comprising:

a main body;

at least one supporting mechanism mounted on the main body, the at least one supporting mechanism comprising;

a support leg being rotatably connected to the main body, configured for supporting the main body;

a positioning leg configured for supporting the support leg;

a shaft, the shaft extending through the support leg and the positioning leg, thus rotatably connecting the positioning leg to the support leg, and

a first elastic member resisted between the support leg and the positioning leg, thus producing an elastic force to drive the positioning leg away from the support leg.

2. The electronic device as claimed in claim 1, wherein the at least one supporting mechanism further comprises a second elastic member disposed between the support leg and the main body to produce an elastic force to drive the support leg to rotate to the main body.

3. The electronic device as claimed in claim 2, wherein the main body comprises a housing, the housing comprises a base plate and a plurality of side plates, the side plates are substantially perpendicularly extending from an edge of the base plate.

4. The electronic device as claimed in claim 3, wherein the base plate defines at least one through hole, two flanges are formed on opposite sides of the at least one through hole, each flange defines an assembling groove thereof, the at least one supporting mechanism further comprises a first shaft, the first shaft extends through the support leg, and two ends of the first shaft are received in the assembling grooves of the flanges respectively.

5. The electronic device as claimed in claim 4, wherein the at least one supporting mechanism further comprises a cover, the cover is fixed to the base plate and opposite to the support leg.

6. The electronic device as claimed in claim 5, wherein the cover defines a receiving groove in a surface opposite to the support leg, and the receiving groove is configured for receiving an end of the positioning leg.

7. The electronic device as claimed in claim 6, wherein the cover further defines a first limiting groove and a second limiting groove on opposite ends thereof, a first limiting piece and a second limiting piece are formed at opposite ends of the at least one through hole of the base plate respectively, the first limiting piece engages with the first limiting groove of the cover, and the second limiting piece engages with the second limiting groove of the cover.

8. The electronic device as claimed in claim 1, wherein the first elastic member is a torsion spring sleeved on the second shaft.

9. The electronic device as claimed in claim 1 being a notebook computer.

10. An electronic device, comprising:

a main body;

a display body rotatably connected to the main body;

at least one supporting mechanism comprising;

a support leg being rotatably connected to the main body, configured for supporting the main body;

a positioning leg being rotatably connected to the support leg, configured for supporting the support leg; and

a resilient member disposed between the support leg and the main body, to produce a resilient force to drive the support leg rotating to the main body.

11. The electronic device as claimed in claim 10, wherein the main body comprises a housing, the housing comprises a base plate and a plurality of side plates, the side plates are substantially perpendicularly extending from an edge of the base plate.

12. The electronic device as claimed in claim 11, wherein the base plate defines at least one through hole, two flanges are formed on opposite sides of the at least one through hole, each flange defines an assembling groove thereof, the at least one supporting mechanism further comprises a first shaft, the first shaft extends through the support leg, and two ends of the first shaft are received in the assembling grooves of the flanges respectively.

13. The electronic device as claimed in claim 12, wherein the at least one supporting mechanism further comprises a cover, the cover is fixed to the base plate and opposite to the support leg.

14. The electronic device as claimed in claim 13, wherein the cover defines a receiving groove in a surface opposite to the support leg, and the receiving groove is configured for receiving an end of the positioning leg.

15. The electronic device as claimed in claim 14, wherein the cover further defines a first limiting groove and a second limiting groove on opposite ends thereof, a first limiting piece and a second limiting piece are formed at opposite ends of the at least one through hole respectively, the first limiting piece engages with the first limiting groove of the cover, and the second limiting piece engages with the second limiting groove of the cover.

16. The electronic device as claimed in claim 10, wherein the at least one supporting mechanism further comprises a second shaft, the second shaft extends through the support leg and the positioning leg, thus the positioning leg is rotatably connected to the support leg.

17. The electronic device as claimed in claim 10 being a notebook computer.
