Abstract

A non-contact power reception apparatus is provided, in which a power reception coil for a charging system and a loop antenna for an electronic settlement system are mounted on a battery pack and a cover case of a portable terminal such that the power reception coil is arranged in the center thereof and the loop antenna is disposed outside the power reception coil, so that a mode of receiving a wireless power signal and a mode of transmitting and receiving data are selectively performed, thereby preventing interference from harmonic components and enabling non-contact charging and electronic settlement using a single portable terminal. A jig for fabricating a core to be mounted to the non-contact power reception apparatus is provided.

First claim

The invention claimed is:

1. An apparatus, comprising:
a common module that includes a power reception coil capable of receiving a wireless power signal from a non-contact power transmission apparatus and a communication antenna capable of transmitting or receiving a wireless data signal;
a connection unit configured to couple the power reception coil to a rectification block and couple the communication antenna to a data processing block;
the data processor configured to process the wireless data signal transmitted or received by the communication antenna of the common module; and
the rectification block configured to rectify the wireless power signal received by the power reception coil of the common module.

2. The apparatus of claim 1 , wherein the power reception coil is first wound wire of a secondary core and wherein communication antenna is a second wound wire forming a loop antenna.

3. The apparatus of claim 2 , wherein the communication antenna is used for an electronic payment based on the wireless data signal, the wireless data signal including information related to the electronic payment.

4. The apparatus of claim 1 , further comprising:
a mode control unit configured to:
detect a received voltage of the power reception coil, and control a mode switching unit of the connection unit based, at least in part, on the received-voltage of the power reception coil, wherein the mode switching unit enables the connection unit to alternatively couple the power reception coil to the rectification block for a first operation mode or couple the communication antenna to the data processing block for a second operation mode.

5. The apparatus of claim 4 , further comprising:
the mode control unit configured to:
cause the mode switching unit to couple the power reception coil to the rectification block if the detected received voltage is higher than a reference voltage; and
cause the mode switching unit to couple the communication antenna to the data processing block if the detected received voltage is lower than the reference voltage.

6. The apparatus of claim 4 , wherein the mode switching unit is configured to disable the second operation mode when the first operation mode is enabled.

7. The apparatus of claim 1 , further comprising:
a battery cell which is rechargeable and supplies an electric energy to components in the apparatus, wherein the power reception coil and the communication antenna are positioned at a same side of the battery cell and are positioned in parallel with the battery cell.

8. The apparatus of claim 7 , further comprising:
a charging control block which controls a charging of the battery cell using the rectified wireless power signal from the rectification block.

9. The apparatus of claim 1 , wherein communication antenna is a loop antenna that loops outside the power reception coil.

10. The apparatus of claim 1 , further comprising a double-structure core that includes both the communication antenna and the power reception coil.

11. The apparatus of claim 1 , wherein the power reception coil forms a circular shape and the communication antenna forms a rectangular shape.

12. The apparatus of claim 1 , wherein the power reception coil and the communication antenna are arranged on the same plane.

13. A method in a portable terminal, comprising:
connecting, by a connection unit of the portable terminal, first wound wire to a rectification block and a communication antenna to a data processing block, the power reception coil capable of receiving a wireless power signal from a non-contact power transmission apparatus, the communication antenna capable of transmitting or receiving or transmitting a wireless data signal, wherein the power reception coil and the communication antenna are in a common module of the portable terminal;
processing, in a data processing block, the wireless data signal received or transmitted by the communication antenna of the common module; and
rectifying, in a rectification block, the wireless power signal when the mode control unit selects the second operation mode received by the power reception coil of the common module.

14. The method of claim 13 , wherein further comprising:
detecting a received voltage of the power reception coil;
controlling, by a mode control unit of the portable terminal, a mode switching unit of the connection unit based, at least in part, on the received voltage of the power reception coil, wherein the mode switching unit enables the connection unit to alternatively couple the power reception coil to the rectification block for a first operation mode or couple the communication antenna to the data processing block for a second operation mode.

15. The method of claim 14 , wherein controlling the mode switching unit includes:
causing the mode switching unit to couple the power reception coil to the rectification block if the detected received voltage is higher than a reference voltage; and
causing the mode switching unit to couple the communication antenna to the data processing block if the detected received voltage is lower than the reference voltage.

16. The method of claim 13 , wherein the power reception coil is a power reception coil for receiving the wireless power signal and the communication antenna is a communication antenna for transmitting or receiving the wireless data signal.

17. The method of claim 16 , wherein the communication antenna is used for an electronic payment based on the wireless data signal, the wireless data signal including information related to the electronic payment.

18. The method of claim 14 , further comprising:
disabling the second operation mode when the first operation mode is enabled.

19. The method of claim 13 , wherein communication antenna is a loop antenna that loops outside the power reception coil, and wherein the power reception coil and the communication antenna are arranged on the same plane.

20. The method of claim 13 , wherein the power reception coil forms a circular shape and the communication antenna forms a rectangular shape.
