Abstract

An electronic device includes a main body and a leg. The main body includes a restriction portion. The leg is rotatably connected to the main body for supporting the main body. The leg defines grooves for being engageable with the restriction portion. When the leg rotates relatively to the main body, the restriction portion is operable to be selectively engaged with any one of the grooves to adjust a predetermined angle defined by the leg and the main body.

Claims

1. An electronic device, comprising:

a main body comprising a restriction portion partly exposed from the main body; and

a leg, the leg rotatably connected to the main body for supporting the main body, the leg defining grooves for being engageable with the exposed part of the restriction portion;

wherein when the leg rotates relatively to the main body and the restriction portion is engaged with one of the grooves, by adjusting the angle between the leg and the main body to a predetermined angle, the restriction portion is deformed and engaged with another one of the grooves to keep the leg and the main body in the predetermined angle.

2. The electronic device of claim 1, wherein the grooves are substantially aligned in an arc.

3. The electronic device of claim 2, wherein the leg comprises a wheel member and a shaft, the shaft is operable to rotate relative to the main body, the wheel member is coaxial with the shaft, the grooves are defined on the surface of the wheel member.

4. The electronic device of claim 3, wherein the wheel member is gear-shaped, and comprises a plurality of cogs radially extending from thereof, the grooves are further defined between each two adjacent cogs.

5. The electronic device of claim 1, wherein the leg comprises a brake portion, the brake portion is operable to abut the main body to define the maximum predetermined angle.

6. The electronic device of claim 1, wherein the main body comprises a front body and a rear cover covering the back of the front body, the rear cover comprises an elastic restriction member rotatably connected with the leg, the restriction portion is formed on the elastic restriction member.

7. The electronic device of claim 6, wherein the rear cover further comprises an outer surface and an inner surface opposite to the outer surface, the inner surface faces the front body, while the outer surface faces away from the front body, the rear cover has a hole for receiving the restriction portion.

8. The electronic device of claim 7, wherein the elastic restriction member further comprises a fixing portion and a connecting portion, the fixing portion protrudes from the inner surface and adjacent to the hole, the connecting portion perpendicularly extends from the fixing portion and faces the hole, the restriction portion is formed on the end of the connecting portion and extends into the hole.

9. The electronic device of claim 8, wherein the rear cover further defines a receiving portion used for receiving the leg, the hole is adjacent to a side of the receiving portion and defined at the bottom of the receiving portion, the restriction portion are partly exposed from the receiving portion through the hole.

10. The electronic device of claim 9, wherein the receiving portion further defines a pair of pivot holes which are coaxially located at two opposite sides thereof, the hole is positioned between the two pivot holes, the leg comprises two pivots as a shaft of the leg, the two pivots of the shaft are received in the two pivot holes respectively so that the leg is rotatably connected with the rear cover.

11. An electronic device, comprising:

a main body comprising an elastic restriction member, the elastic restriction member having a restriction portion partly exposed from the main body; and

a leg connected to the main body for supporting the main body, the leg comprising a plurality of cogs, each of two adjacent cogs being operable to hold the exposed part of the restriction portion, by adjusting the angle between the leg and the main body to a predetermined angle, the restriction portion is pressed by the corresponding cog, and the elastic restriction member is deformed to make way for the cog rotating, thus the restriction portion is held by another two adjacent cogs for keeping the leg and the main body in the predetermined angle.

12. The electronic device of claim 11, wherein grooves are defined by each two adjacent cogs, the restriction portion is selectively engaged with any one of the grooves to keep the leg and the main body in the predetermined angle.

13. The electronic device of claim 11, wherein the plurality of cogs is substantially aligned in an arc.

14. The electronic device of claim 11, wherein the leg comprises wheel member and a shaft, the shaft is operable to rotate relative to the main body, the wheel member is coaxial to the shaft, the plurality of cogs is formed on the surface of wheel member.

15. The electronic device of claim 11, wherein the plurality of cogs is gear-shaped.

16. The electronic device of claim 12, wherein the leg comprises a brake portion, the brake portion is operable to be blocked by the main body to define the maximum predetermined angle.

17. The electronic device of claim 11, wherein the main body further comprises a housing for receiving the leg, the housing defines a hole, the restriction portion is received in the hole and partly expose from the main body through the hole.

18. The electronic device of claim 17, wherein the elastic restriction member further comprises a fixing portion and a connecting portion, the fixing portion protrudes from the housing and adjacent to the hole, the connecting portion perpendicularly extends from the fixing portion and faces the hole, the restriction portion is formed on the end of the connecting portion and extends into the hole.

19. The electronic device of claim 18, wherein the elastic restriction member is received in the hole.

20. An electronic device, comprising:

a main body;

a leg rotatably connected to the main body for supporting the main body; and

an adjusting device for adjusting a predetermined angle defined by the leg and the main body, the adjusting device comprising a first member and a second member which is rotatably engaged with the first member;

wherein the first member defines grooves, the second member comprises an elastic restriction portion corresponding to the grooves, and the restriction portion is engaged with one of the grooves of the first member;

by adjusting the angle between the leg and the main body to a predetermined angle, the restriction portion is deformed and engaged with another one of the grooves to keep the leg and the main body in the predetermined angle.
