Abstract

A wireless charging apparatus includes a charging unit configured to transmit power wirelessly to a mobile device, and a power supply unit configured to supply power to the charging unit. The wireless charging apparatus further includes a connecting unit configured to connect the charging unit to the power supply unit such that a position and an angle of the charging unit are adjustable.

Claims

1. A wireless charging apparatus comprising:

a charging unit configured to transmit power wirelessly to a mobile device;

a power supply unit configured to supply power to the charging unit; and

a connecting unit configured to connect the charging unit to the power supply unit such that an angle between the charging unit and the power supply unit is adjustable,

wherein the connecting unit is adjustable flexibly to adjust an arrangement of the charging unit and the power supply unit freely.

2. The wireless charging apparatus of claim 1, wherein a resonator of the mobile device is disposed on a resonator of the charging unit in a face-to-face arrangement to maximize an efficiency of the transmission.

3. The wireless charging apparatus of claim 1, wherein the connecting unit is further configured to connect the charging unit to the power supply unit such that an angle between a plane of the charging unit and a plane of the power supply unit is adjustable.

4. The wireless charging apparatus of claim 1, wherein the connecting unit is further configured to connect the charging unit to the power supply unit such that the charging unit is rotatable clockwise or counterclockwise.

5. The wireless charging apparatus of claim 1, wherein a length of the connecting unit is adjustable.

6. The wireless charging apparatus of claim 1, wherein the mobile device is disposed horizontally or vertically on the charging unit.

7. The wireless charging apparatus of claim 1, wherein the charging unit comprises an inductor or a resonator configured to transmit the power wirelessly to the mobile device.

8. The wireless charging apparatus of claim 1, wherein the charging unit comprises a holder configured to prevent movement of the mobile device disposed on the charging unit.

9. The wireless charging apparatus of claim 1, wherein a resonator of the mobile device is disposed on a resonator of the charging unit, and an angle between the resonator of the mobile device and the resonator of the charging unit is 0 degrees.

10. A wireless charging apparatus comprising:

a charging unit configured to transmit power wirelessly to a device disposed on the charging unit and in parallel to the charging unit;

a power supply unit configured to supply power to the charging unit; and

a connecting unit configured to connect the charging unit to the power supply unit such that an angle between the charging unit and the power supply unit is adjustable,

wherein the connecting unit is adjustable flexibly to adjust an arrangement of the charging unit and the power supply unit freely.

11. The wireless charging apparatus of claim 10, wherein a resonator of the device is disposed on a resonator of the charging unit, and an angle between the resonator of the device and the resonator of the charging unit is 0 degrees.

12. The wireless charging apparatus of claim 10, wherein the connecting unit is further configured to connect the charging unit to the power supply unit such that the position of the charging unit is adjustable and the device is maintained in parallel to the charging unit.

13. The wireless charging apparatus of claim 10, wherein the charging unit comprises a holder configured to hold the device in a position on the charging unit.

14. The wireless charging apparatus of claim 10, wherein the connecting unit comprises a second joint unit configured to connect the charging unit to the power supply unit such that an angle between a plane of the charging unit and a plane of the power supply unit is adjustable.

15. The wireless charging apparatus of claim 10, wherein the connecting unit comprises a first joint unit configured to connect the charging unit to the power supply unit such that the charging unit is rotatable clockwise or counterclockwise.

16. The wireless charging apparatus of claim 10, wherein the connecting unit comprises an extension unit configured to connect the charging unit to the power supply unit such that a length of the connecting unit is adjustable.

17. The wireless charging apparatus of claim 10, wherein the charging unit comprises grooves, and holders disposed in the grooves and configured to hold the device horizontally or vertically in an adjustable position on the charging unit.
