Abstract

A charging device used in a handheld device comprises a main body, a coupling portion connected to an end of the main body and the coupling portion has a connector, and a battery unit connected to another end of the main body. When the charging device is in a first status, the battery unit and the connector are coupled together; when it is in a second status, the battery unit is detached from the connector so that the connector is electrically connected with the handheld device in order to have the handheld device charged.

Claims

1. A charging device used in a handheld device:

comprising;

a main body;

a coupling portion connected to a first end of the main body and the coupling portion having a connector; and

a battery unit connected to a second end of the main body, wherein when the charging device is in a non charging status, the battery unit and the connector are coupled together;

when the charging device is in a charging status, the battery unit is detached from the connector so that the connector is electrically connected with the handheld device in order to have the handheld device charged.

2. The charging device used in the handheld device as claimed in claim 1, wherein a bent portion is disposed between the main body and the battery unit.

3. The charging device used in the handheld device as claimed in claim 2, wherein the bent portion is flexible.

4. The charging device used in the handheld device as claimed in claim 3, wherein a rigidity of the bent portion is lower than rigidity of the main body and the battery unit.

5. The charging device used in the handheld device as claimed in claim 1, wherein the battery unit has a coupling groove for coupling with the connector in the non charging status.

6. The charging device used in the handheld device as claimed in claim 1, wherein the coupling portion is flexible.

7. The charging device used in the handheld device as claimed in claim 1, wherein the connector is a universal serial bus.

8. The charging device used in the handheld device as claimed in claim 1, wherein the battery unit can be overturned relative to the main body in order to be used as a supporting structure.

9. A charging device used in a handheld device comprising:

a main body having a first end and a second end;

a battery unit; and

a flexible bent portion connected to the first end of the main body and the battery unit,

wherein when the charging device is in a first status, the battery unit and a connector of a coupling portion at the second end of the main body are coupled together;

when the charging device is in a second status, the battery unit is detached from the connector so that the connector is electrically connected with the handheld device for charging the handheld device.

10. The charging device used in the handheld device as claimed in claim 9, wherein the first status is a non charging status, and the second status is a charging status.

11. The charging device used in the handheld device as claimed in claim 9, wherein a rigidity of the bent portion is lower than rigidity of the main body and the battery unit.

12. The charging device used in the handheld device as claimed in claim 9, wherein the battery unit has a coupling groove for coupling with the connector in the first status.

13. The charging device used in the handheld device as claimed in claim 9, wherein the coupling portion is flexible.

14. The charging device used in the handheld device as claimed in claim 9, wherein the connector is a universal serial bus.

15. The charging device used in the handheld device as claimed in claim 9, wherein the battery unit can be overturned relative to the main body in order to be used as a supporting structure.

16. A charging device used in a handheld device comprising:

a main body having a first end and a second end;

a battery unit; and

a flexible bent portion connected to the first end of the main body and the battery unit,

wherein when the charging device is in a non charging status, the battery unit and a connector of a coupling portion at the second end of the main body are coupled together;

when the charging device is in a charging status, the battery unit is detached from the connector so that the connector is electrically connected with the handheld device for charging the handheld device.
