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 include 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 recess formed at a side of the body and an exposing hole formed at a portion of the body which defines the receiving recess; and

a charging kit detachably mounted in the receiving recess, and comprising a coil formed to receive power by magnetic coupling with a power supplying device, a charging circuit configured to charge a battery by electromotive force induced in the coil and having a charging terminal configured to be contacted with a first terminal of the battery, and a frame having a closed space accommodating the coil and the charging circuit and a terminal slot configured to receive the charging terminal and disposed to correspond to the exposing hole.

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,

wherein the battery cover includes, a main surface where the exposing hole is formed, a side surface where the entrance of the receiving recess is formed, and a hook configured to be coupled with the portable electronic device.

3. The power receiving device for wireless charging of claim 1, wherein the coil is formed to have any one of a circular shape, a rectangular shape, a track shape, a oval shape, and a combination thereof.

4. The power receiving device for wireless charging of claim 1, wherein the charging kit further comprises a shielding member disposed in the frame leakage of magnetic force of the coil.

5. The power receiving device for wireless charging of claim 1, wherein the frame comprises first and second parts coupled with each other to form the closed space.

6. The power receiving device for wireless charging of claim 5, wherein the frame further comprises a shaft which protrudes from at least one of the first part and the second part to support the coil.

7. 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.

8. The portable electronic device of claim 7, wherein the body further comprises a wireless communication module.

9. The portable electronic device of claim 7, wherein the battery comprises:

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

a second terminal connected to a power terminal of the body.
