Abstract

A charging device applied to a portable mobile communication device is disclosed in the present invention. The charging device includes a base, a supporter and a transmission module. The supporter and the transmission module are disposed on the base in a detachable manner. The transmission module includes a first connector, a second connector and a transmission cable. The first connector is disposed on an opening on the supporter for electrically connecting to a terminal of the portable mobile communication device. The second connector disposed inside an accommodating structure of the base for electrically connecting to an external electronic device. Two ends of the transmission cable are respectively connected to the first connector and the second connector, so that the external electronic device and the portable mobile communication device can transmit electric power via the transmission module.

Claims

1. A charging device applied to a portable mobile communication device, the portable mobile communication device having a connecting interface, the charging device comprising:

a base, the base comprising an accommodating structure;

a supporter detachably disposed on the base, the portable mobile communication device being held by the supporter; and

a transmission module, the transmission module being optionally detachably combined with the accommodating structure of the base to be electrically connected to the portable mobile communication device, or separated from the base and the supporter to be electrically connected to the portable mobile communication device directly and individually, the transmission module comprising;

a first connector capable of being fixed on the supporter, the first connector being for electrically connecting to the connecting interface of the portable mobile communication device;

a second connector capable of being fixed inside the accommodating structure of the base, the second connector being for electrically connecting to an external power supply device or an electronic datum processing device; and

a transmission cable, two ends of the transmission cable being electrically connected to the first connector and the second connector respectively.

2. The charging device of claim 1, wherein the base further comprises a first constraining structure, the supporter comprises a second constraining structure, the second constraining structure is slidably combined with the first constraining structure.

3. The charging device of claim 2, wherein the first constraining structure is a constraint protrusion, the second constraining structure is a constraint slot, and the constraint protrusion slidably inserts into the constraint slot.

4. The charging device of claim 2, wherein the base further comprises a constraining plank whereon a constraint hole is formed, the first constraining structure is formed on the constraining plank, the supporter further comprises a constraining baffle accordingly, the constraining baffle can buckle the constraining hole when the supporter is combined with the first constraining structure via the second constraining structure, so as to constrain a movement of the supporter relative to the base.

5. The charging device of claim 4, wherein the constraining baffle is a resilient unit, and an end of the resilient unit buckles the constraining hole.

6. The charging device of claim 1, wherein the base further comprises a first restraining structure, the second connector comprises a second restraining structure, the second restraining structure is slidably combined with the first restraining structure.

7. The charging device of claim 6, wherein the first restraining structure is a restraint protrusion, the second restraining structure is a restraint slot, and the restraint protrusion slidably inserts into the restraint slot.

8. The charging device of claim 1, wherein the base further comprises a restraint hole formed on an inner wall of the accommodating structure, the second connector further comprises a restraining plank, an end of the restraining plank buckles the restraining hole in a resiliently oscillatory manner to restrain a movement of the second connector relative to the base.

9. The charging device of claim 1, further comprising:

a fixing component detachably disposed between the first connector and the supporter, the fixing component fixing and constraining a movement of the first connector relative to the supporter.

10. The charging device of claim 9, wherein the first connector comprises a first engaging structure, the supporter comprises a second engaging structure, the fixing component slidably inserts into the first engaging structure and the second engaging structure.

11. The charging device of claim 10, wherein the fixing component is an engaging protrusion, the first engaging structure and the second engaging structure respectively are engaging slots, two ends of the engaging protrusion slidably insert into the engaging slots respectively.

12. The charging device of claim 9, wherein the fixing component comprises a resilient arm, the supporter further comprises a contacting portion, an end of the resilient arm buckles the contacting portion to fix and constrain a movement of the fixing component relative to the supporter.

13. The charging device of claim 1, wherein the supporter comprises a holding structure, a contour of the holding structure substantially corresponds to a shape of the portable mobile communication device.

14. The charging device of claim 1, wherein the base further comprises:

a first opening structure disposed on a side of the accommodating structure and adjacent to the supporter, the transmission cable piercing through the accommodating structure via the first opening structure; and

a second opening structure disposed on the other side of the accommodating structure, the second connector being disposed on the second opening structure to be electrically connected to the external power supply device or the electronic datum processing device.

15. The charging device of claim 1, wherein the transmission module further comprises a magnetic component disposed on the first connector, the first connector utilizes the magnetic component to connect to a magnetic unit disposed on the connecting interface of the portable mobile communication device.

16. The charging device of claim 1, wherein the transmission module further comprises an auxiliary charging outputting connector, and the base further comprises:
