Abstract

According to one embodiment, a power relay stand which supports an electronic device includes a receiver, a transfer module and a transmitter. The receiver is provided so as to face a charging stand and receives power transmitted from the charging stand through contactless power transmission. The transfer module transfers the power received by the receiver. The transmitter is provided so as to face the electronic device and transmits the power transferred from the transfer module to the electronic device through the contactless power transmission.

Claims

1. A power relay stand which supports an electronic device, the stand comprising:

a receiver which is provided so as to face a charging stand and receives power transmitted from the charging stand through contactless power transmission;

a transfer module which transfers the power received by the receiver; and

a transmitter which is provided so as to face the device and transmits the power transferred from the transfer module to the device through the contactless power transmission.

2. The power relay stand of claim 1, wherein

the contactless power transmission is performed by electric field coupling,

the receiver comprises a first reception electrode and a second reception electrode which are provided so as to face a first transmission position of the charging stand,

the transmitter comprises a first transmission electrode and a second transmission electrode which are provided so as to face a reception position of the device, and

the transfer module comprises a first relay line electrically connecting the first reception electrode and the first transmission electrode, and a second relay line electrically connecting the second reception electrode and the second transmission electrode.

3. The power relay stand of claim 2, further comprising a first inductor inserted into the first relay line.

4. The power relay stand of claim 3, further comprising a second inductor inserted into the second relay line.

5. The power relay stand of claim 1, wherein the contactless power transmission is performed by electromagnetic induction or magnetic resonance,

the receiver comprises a reception coil provided so as to face a first transmission position of the charging stand, and

the transmitter comprises a transmission coil provided so as to face a reception position of the electronic device.

6. A system comprising an electronic device and a power relay stand supporting the electronic device, wherein

the power relay stand comprises:

a receiver which is provided so as to face a charging stand and receives power transmitted from the charging stand through contactless power transmission;

a transfer module which transfers the power received by the receiver; and

a transmitter which is provided so as to face the electronic device and transmits the power transferred from the transfer module to the electronic device through the contactless power transmission.

7. An electronic device allowed to be supported by a power relay stand, wherein

the power relay stand comprises:

a first receiver which is provided so as to face a charging stand and receives power transmitted from the charging stand through contactless power transmission;

a transfer module which transfers the power received by the receiver; and

a transmitter which is provided so as to face the electronic device and transmits the power transferred from the transfer module to the electronic device through the contactless power transmission, and

the electronic device comprises a second receiver which is provided so as to face the transmitter and which receives the power transmitted through the contactless power transmission.
