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.

Claims

1. A common module for selectively operating between a non-contact charging and a wireless communication, the common module comprising:

a power reception coil arranged on a plane, and configured to receive a wireless power signal from a non-contact power transmission apparatus;

a communication antenna arranged on a plane which loops outside the power reception coil, and is configured to wirelessly transmit or receive data with an external electronic device; and

a connector configured to connect a portable terminal with at least the power reception coil or the communication antenna,

wherein the power reception coil and the communication antenna are arranged within the common module such that the power reception coil and the communication antenna are positioned at a same side of a battery cell in the portable terminal, and the power reception coil and the communication antenna are positioned in parallel with the battery cell in the portable terminal.

2. The common module of claim 1, wherein the communication antenna is used for an electronic payment based on the data transmitted or received with the external electronic device, and the data includes information related to the electronic payment.

3. The common module of claim 1, wherein the power reception coil is configured to be connected with a rectification block of the portable terminal, and the communication antenna is configured to be connected with a data processor of the portable terminal.

4. The common module of claim 1, wherein the power reception coil is a circular shape made with a thin metal wire.

5. The common module of claim 1, wherein the power reception coil and the communication antenna are arranged on a same plane within the common module.

6. A portable terminal comprising:

a common module configured to selectively operate between a non-contact charging and a wireless communication including;

a power reception coil arranged on a plane, and configured to receive a wireless power signal from a non-contact power transmission apparatus; and

a communication antenna arranged on a plane which loops outside the power reception coil, and is configured to wirelessly transmit or receive data with an external electronic device;

a battery cell which is rechargeable and supplies an electric energy to components in the portable terminal;

a data processor connected to the communication antenna to process the data;

a rectification block which rectifies the wireless power signal and supplies a power to the battery cell;

a charging control block which controls a charging of the battery cell; and

a shield sheet which is mounted on one side of the power reception coil to protect electric circuit elements in the portable terminal from electromagnetic waves,

wherein the power reception coil and the communication antenna are arranged within the common module such that the power reception coil and the communication antenna are positioned at a same side of the battery cell, and the power reception coil and the communication antenna are positioned in parallel with the battery cell.

7. The portable terminal of claim 6, wherein the communication antenna is used for an electronic payment based on the data transmitted or received with the external electronic device, and the data includes information related to the electronic payment.

8. The portable terminal of claim 6, wherein the power reception coil is connected to the rectification block.

9. The portable terminal of claim 6, wherein the power reception coil is a circular shape made with a thin metal wire.

10. The portable terminal of claim 6, wherein the power reception coil and the communication antenna are arranged on a same plane within the common module.

11. The portable terminal of claim 6, wherein, when the portable terminal operates in a first mode, which the portable terminal receives the wireless power signal by the power reception coil, the portable terminal disables a second mode which the portable terminal processes an electric payment based on the data wirelessly transmitted or received by the communication antenna.
