Therefore, when clothes, which are objects, are attached to the body, the shield 630 may protect the body from the wireless power transmission signal. The shield 630 may be configured using a conventionally known conductive material for shielding electromagnetic waves. For example, materials, such as copper, aluminum, iron, lead, and a conductive polymer, are processed into a thin plate shape, or the fiber impregnated with these materials is mentioned.

In addition, in order to increase the charging efficiency of the wireless power, it is advantageous that the position of the transmission inductor unit of the portable terminal and the position of the reception inductor unit 120 of the wireless power receiver 100 are as close as possible. However, since the size and shape of the accommodating part 110, the size and shape of the portable terminal, and the positions of the transmitting inductor part of the portable terminal vary greatly, when the portable terminal is actually placed in the accommodating part 110, the transmitting inductor part and the receiving inductor The unit 120 may be separated so that power reception may not be good.

Therefore, according to an embodiment of the present invention, since the mobile terminal is generally located at the lower end of the accommodating part 110 by gravity, the receiving inductor part 120 is also the accommodating part 110 as shown in FIG. 7. It can be located at the bottom of the.

In general, the position of the transmission inductor of the mobile terminal can be divided into upper, middle, and lower positions. When the mobile terminal is turned 180 degrees, the upper and lower positions can be changed. It is preferable.

According to an embodiment of the present invention, the electronic circuit unit 130 may further include a short range communication module for communicating with a short range communication module provided in the portable terminal. Hereinafter, for convenience of description, a short range communication module included in the electronic circuit unit 130 will be referred to as a "first short range communication module" and a short range communication module provided in the portable terminal will be referred to as a "second short range communication module". .

In this case, according to the first embodiment of the present invention, when detecting the first short range communication module through the second short range communication module, the portable terminal may transmit a wireless power transmission signal.

That is, when the second short range communication module of the portable terminal does not detect the first short range communication module of the wireless power receiver 100 (for example, when the portable terminal is not stored in the accommodating unit 100), The portable terminal does not transmit the wireless power transmission signal. However, when the second short range communication module detects the first short range communication module, the portable terminal transmits a wireless power transmission signal.

Therefore, according to the second embodiment of the present invention, when the portable terminal operates in the scan mode, that is, when neither the first short range communication module nor the second short range communication module detects each other, the at least one light emitting element is periodically You can repeat on and off with. Here, for the scan mode, there is no first short range communication module, or if there is a transmission inductor for wireless power transmission and the inductor for the first short distance communication module must be different from each other, and the two inductors are located at a distance not connected to each other at the same time. Should be

In contrast, when the mobile terminal operates in the sink mode, that is, when the first short range communication module and the second short range communication module communicate with each other, the at least one light emitting device may be always turned on. This utilizes the periodicity of the scan mode / sink mode of the portable terminal.

In addition, according to the third embodiment of the present invention, when the electrical and electronic device is at least one light emitting device, the electronic circuit unit 130 may further include a light emitting device controller for controlling the on / off of at least one light emitting device. have.

Here, according to an embodiment of the present invention, the first short-range communication module of the electronic circuit unit 130 receives the light emitting device on / off control signal from the second short-range communication module of the portable terminal and transmits to the light emitting device controller, The device controller may control on / off of at least one light emitting device based on the light emitting device control signal.

For example, the portable terminal may generate a light emitting device control signal through a pre-installed mobile app and transmit it to the first short range communication module through the second short range communication module. In this case, since the light emitting device control signal is generated through the mobile app, various patterns or characters may be expressed in various colors through a combination of dots, lines, and surfaces of at least one light emitting device.

In short, the present invention provides a portable terminal by providing a storage unit 110 having an induction coil (receiving inductor unit 120) to a wearable item such as clothes or a bag to which a smart device is applied, without a heavy and complicated device such as a generator. Just by putting it there is an advantage that can drive electric and electronic devices such as LED. Therefore, there is an advantage that does not secure a separate space for adding a power supply device, and does not reduce the fit of the wearable item due to the flexible material. In addition, when the housing 110 is removed from the object by the fixing unit, the receiving inductor unit 120 and the electronic circuit unit 130 may be removed when washing clothes. In addition, it is possible to waterproof the receiving inductor unit 120 and the electrical and electronic devices to be waterproof from snow / rain / water has an advantage of excellent environmental resistance. In this case, the method of coating the polymer inductor 120 and the electrical and electronic device to the waterproof treatment method is universal, but a variety of published methods are also applicable.
