Abstract

Disclosed herein are a power receiving device for wireless charging and a portable electronic device having the same. The power receiving device for wireless charging includes a body having a receiving space formed therein; and a charging kit detachably received in the receiving space, and including a coil formed to receive power by magnetic coupling with a power supplying device and a charging circuit configured to charge a battery by electromotive force induced in the coil.

Claims

1. A power receiving device for wireless charging comprising:

a body having a receiving space formed therein; and

a charging kit detachably received in the receiving space, and comprising a coil formed to receive power by magnetic coupling with a power supplying device and a charging circuit configured to charge a battery by electromotive force induced in the coil.

2. The power receiving device for wireless charging of claim 1, wherein the body comprises a battery cover coupled with a portable electronic device which covers the battery mounted in the portable electronic device.

3. The power receiving device for wireless charging of claim 1, wherein the receiving space is formed so that the charging kit is received through a side of the battery cover.

4. The power receiving device for wireless charging of claim 1, wherein the receiving space comprises a surface in parallel with a main surface of the battery cover.

5. The power receiving device for wireless charging of claim 1, wherein the charging kit further comprises

a frame enclosing the coil and the charging circuit and forming an exterior.

6. The power receiving device for wireless charging of claim 5, wherein the coil is formed to have any one of a substantially circular shape, a substantially rectangular shape, a substantially track shape, substantially oval shape, and a combination thereof.

7. The power receiving device for wireless charging of claim 5, wherein the charging circuit comprises a charging terminal connected to a first terminal of the battery.

8. The power receiving device for wireless charging of claim 5, wherein the charging kit further comprises a shielding member disposed in the frame leakage of magnetic force of the coil.

9. The power receiving device for wireless charging of claim 5, wherein the frame comprises first and second parts coupled with each other to form an internal space with which the coil and the charging circuit are disposed.

10. The power receiving device for wireless charging of claim 9, wherein the frame further comprises a shaft which protrudes from at least one of the first and second parts to support the coil.

11. The power receiving device for wireless charging of claim 9, wherein

the charging circuit comprises a charging terminal formed to be connected to a terminal of the battery, and

any one of the first and second part comprises a terminal slot exposing the charging terminal.

12. The power receiving device for wireless charging of claim 1, wherein the body comprises a portable electronic device within which the battery is mounted.

13. A portable electronic device comprising:

a body comprising a display and a battery supplying power to the display; and

the power receiving device for wireless charging of claim 1 which supplies the power to the battery.

14. The portable electronic device of claim 13, wherein the body further comprises a wireless communication module.

15. The portable electronic device of claim 13, wherein the battery comprises:

a first terminal connected to the power receiving device for wireless charging; and

a second terminal connected to a terminal of the body.
