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 non-contact power reception apparatus comprising:

a common transmission and reception block selectively performing a mode of receiving a wireless power signal and a mode of transmitting and receiving a data;

a rectification block rectifying the power signal received by the common transmission and reception block in the mode of receiving the wireless power signal;

a received-power control block controlling the power signal rectified by the rectification block;

a charging control block controlling charging of a battery pack using electric energy of the power signal controlled by the received-power control block; and

a data processing block transmitting and receiving the data via the common transmission and reception block in the mode of transmitting and receiving data,

wherein the common transmission and reception block includes;

a power reception coil receiving the wireless power signal;

a loop antenna for the transmission and reception of the data;

a mode switching unit selecting either one of the power reception coil and the loop antenna and allowing electrical connection to either one of the rectification block and the data processing block; and

a mode control unit detecting a received-voltage of the power reception coil and controlling a switching operation of the mode switching unit.

2. The non-contact power reception apparatus according to claim 1, wherein the mode control unit performs a control operation so that,

if the detected received-voltage is higher than a reference voltage, the mode switching unit performs the switching operation to electrically connect the power reception coil and the rectification block, and

if the detected received-voltage is lower than the reference voltage, the mode switching unit performs the switching operation to electrically connect the loop antenna and the data processing block.

3. The non-contact power reception apparatus according to claim 2, wherein the mode control unit includes a voltage detector for detecting the received-voltage of the power reception coil, comparing the detected received-voltage with the reference voltage and outputting the comparison result.

4. The non-contact power reception apparatus according to claim 1, wherein the data is the data for electronic settlement with an external electronic device.
