Abstract

A portable electronic device (100) is described including a housing (10) and a supporting mechanism (30) supporting the housing. The supporting mechanism includes a shaft (32) secured relative to the housing, a gear (34) rotatably secured with the shaft, a supporting rod (36) secured with the gear, and a rack (38) secured relative to the housing, and further relative to the gear and supporting rod by a meshing of the gear with the rack. The meshing can be changed to drive the supporting rod to rotate relative to the rack and the shaft along with a rotation of the gear about the shaft and along the rack.

Claims

1. A supporting mechanism, comprising:

a shaft;

a gear rotatably connected with the shaft;

a supporting rod connected with the gear; and

a rack secured relative to the gear and the supporting rod by a meshing of the gear with the rack, the meshing being changed to drive the supporting rod to rotate relative to the rack and the shaft along with a rotation of the gear about the shaft and along the rack.

2. The supporting mechanism as claimed in claim 1, wherein the gear comprises a plurality of gear teeth, the rack comprises at least one rack tooth, and the rack tooth meshes with one of the gear teeth and can be adjusted to mesh with another one of the gear teeth by the rotation of the gear along the rack.

3. The supporting mechanism as claimed in claim 2, wherein the rotation of the gear about the shaft and along the rack is driven by a rotation of the supporting rod about the shaft.

4. The supporting mechanism as claimed in claim 3, wherein:

the gear comprises a gear portion and a shaft portion;

the plurality of gear teeth are arranged on the gear portion; and

the supporting rod defining a through slot securing the shaft portion therein.

5. The supporting mechanism as claimed in claim 4, wherein the gear defines a shaft hole through the gear portion and the shaft portion, the shaft hole rotatably securing the shaft therein.

6. The supporting mechanism as claimed in claim 4, wherein the supporting rod comprises a body, a securing head and a supporting foot, the body connecting the securing head with the supporting foot, the through slot defined through the securing head.

7. The supporting mechanism as claimed in claim 6, wherein the supporting rod further comprises another supporting foot, the two supporting feet arranged from the same end of the body, a combination of the two supporting feet and the body is generally Y-shaped.

8. The supporting mechanism as claimed in claim 2, wherein the rack is L-shaped around the gear, and the rack tooth is arranged above the gear.

9. A portable electronic device, comprising:

a housing;

a supporting mechanism supporting the housing, comprising;

a shaft secured relative to the housing;

a gear rotatably secured with the shaft;

a supporting rod secured with the gear; and

a rack secured relative to the housing, and further relative to the gear and supporting rod by a meshing of the gear with the rack, the meshing being changed to drive the supporting rod to rotate relative to the rack and the shaft along with a rotation of the gear about the shaft and along the rack.

10. The portable electronic device as claimed in claim 9, wherein:

the housing defines a through groove and comprises two bulges, the through groove positioned between the bulges;

the shaft secured on the bulges and above the through groove; and

the gear is secured between the bulges;

the supporting rod having a part passing through the through groove to be secured to the gear.

11. The portable electronic device as claimed in claim 10, wherein the rack is secured to the housing and adjacent to the budges.

12. The portable electronic device as claimed in claim 11, wherein the gear comprises a plurality of gear teeth, the rack comprises at least one rack tooth, and the rack tooth meshes with one of the gear teeth and can be adjusted to mesh with another one of the gear teeth by the rotation of the gear along the rack.

13. The portable electronic device as claimed in claim 12, wherein the rotation of the gear about the shaft and along the rack is drived by a rotation of the supporting rod about the shaft.

14. The portable electronic device as claimed in claim 13, wherein:

the gear comprises a gear portion and a shaft portion;

the plurality of gear teeth are arranged on the gear portion; and

the supporting rod defining a through slot securing the shaft portion therein.

15. The portable electronic device as claimed in claim 14, wherein the gear defines a shaft hole through the gear portion and the shaft portion, the shaft hole rotatably securing the shaft therein.

16. The portable electronic device as claimed in claim 14, wherein the supporting rod comprises a body, a securing head and a supporting foot, the body connecting the securing head with the supporting foot, the through slot defined through the securing head, the securing head passes through the through groove.

17. The portable electronic device as claimed in claim 15, wherein the supporting rod further comprises another supporting foot, the two supporting feet arranged from the same end of the body, a combination of the two supporting feet and the body is generally Y-shaped.

18. The portable electronic device as claimed in claim 11, wherein the rack is L-shaped around the gear, and the rack tooth is arranged above the gear.
