Abstract

A portable electrical power source configured to provide power for a portable electronic device includes a base, a chargeable battery, a connector, and at least one locking structure. The base includes a first surface and a second surface facing away from the first surface. The base defines a receiving room between the first surface and the second surface and at least one cavity. The chargeable battery is received in the receiving room. The locking structures are rotatably received in the cavities to lock the portable electronic device onto the first surface of the base. The connector is positioned on the first surface and is electrically connected to the chargeable battery and the portable electronic device. The chargeable battery charges the portable electronic device through the connector.

Claims

1. A portable electrical power source configured to provide power for a portable electronic device, the portable electrical power source comprising:

a base comprising a first surface and a second surface facing away from the first surface, the base defining a receiving room between the first surface and the second surface, and at least one cavity, the base further comprising a bottom surface connected between the first surface and the second surface, the base further comprising a supporting substrate extending upward from an end of the first surface adjacent to the bottom surface, the supporting substrate defining a receiving cavity for receiving the connector, the receiving cavity comprising a first receiving cavity and a second receiving cavity communicating with the first receiving cavity;

a chargeable battery received in the receiving room;

at least one locking structure rotatabley received in the at least one cavity and configured for locking the portable electronic device onto the first surface of the base; and

a connector positioned on the first surface and electrically connected to the chargeable battery, the connector configured to electrically connected to the portable electronic device, the chargeable battery charging the portable electronic device through the connector, the connector comprising a supporting portion and a connecting portion connected to the supporting portion, the supporting portion completely received in the second receiving cavity, one end of the connecting portion fixedly connected to the supporting portion and received in the first receiving cavity, the other end of the connecting portion extending out of the first receiving cavity.

2. The portable electrical power source of claim 1, wherein the base comprises a power button, when the power button is pressed, the portable electronic device is charged by the portable electrical power source, when the portable electronic device is pressed again, the portable electrical power source stop charging the portable electronic device.

3. The portable electrical power source of claim 2, wherein the base comprises power indicator configured to display the amount of power remaining in the chargeable battery.

4. The portable electrical power source of claim 3, wherein both the power button and the power indicator are positioned on the second surface.

5. The portable electrical power source of claim 1, wherein a height of the supporting portion is shorter than a height of the second receiving cavity, and the supporting portion is capable of moving in the second receiving cavity to adjust a position of the connector with respect to the supporting substrate.

6. The portable electrical power source of claim 1, wherein each locking structure comprises a locking portion, a torsion spring and a fixed pole, the locking portion is rectangular, and each of the locking portions is rotatably received in the cavity by the torsion spring and the fixed pole.

7. The portable electrical power source of claim 6, wherein the cavity is rectangular and comprises three sidewalls, the three sidewalls of each cavity defines a blind hole, a first through hole aligning with the blind hole, and a first receiving hole, one end of each of the locking portions defines a third receiving cavity, the third receiving cavity is rectangular, and comprises three internal sidewalls, each of the three internal sidewalls of the third receiving cavity defines a second through hole corresponding to the blind hole, a second receiving hole corresponding to the first receiving hole, and a third through hole corresponding to the first through hole, the first through hole runs through the bottom surface, one end of the torsion spring is inserted into the second receiving hole and the other end of the torsion spring is inserted into the first receiving hole, one end of the fixed pole runs through the first through hole, the torsion spring is received in the blind hole.

8. The portable electrical power source of claim 7, wherein one end of the first through hole in the bottom surface forms internal threads, the fixed pole comprises external threads formed on formed on an end of it, a length of the fixed pole is equal to a distance between the bottom surface and a bottom of the blind hole, and the external threads engage with the internal threads of the first through hole.

9. The portable electrical power source of claim 6, wherein each of the locking structures comprises a plastic plate positioned on an internal sidewall of the locking portion.

10. The portable electrical power source of claim 1, wherein the base comprises a top surface facing away from the bottom surface, and two opposite sidewalls connected between the first surface and the second surface, each of the top surface and the two opposite sidewalls defines a cavity, and the number of the locking structure corresponds to the number of the cavity.

11. The portable electrical power source of claim 10, wherein the base comprises a first charging port for charging the chargeable battery.

12. The portable electrical power source of claim 11, wherein the first charging port is positioned on the top surface.
