Description
A wireless charging device is disclosed. More particularly, the present invention relates to a wireless charging apparatus having an information transmission function.
Portable devices such as smart phones and tablets have built-in rechargeable batteries. A separate charger is required to charge the battery of the portable device. Generally, the charger is connected to the commercial power line by wire, and charges the battery by the power supplied from the commercial power source.
However, since the connection terminal of the rechargeable battery is exposed to the outside, there is a high possibility that the connection terminal is contaminated by foreign substances such as dust. However, if the connection terminal is contaminated, the charging can not be normally performed.
In order to solve such a problem, a wireless charging technology has recently been developed and used in portable devices. If the portable device is placed on a wireless charger, the battery inside the portable device can be charged without a cable.
However, since the conventional wireless charger simply has a charging function, its utilization is limited.
A wireless charging apparatus having an information transmission function is disclosed.
According to an aspect of the present invention, there is provided a wireless charging apparatus having an information transmission function, including: a body in which a portable device is placed for wireless charging; A first surface of a first printed circuit board on which a wireless charging module for wireless charging is mounted, and a second surface of the first printed circuit board on which a beacon for transmitting information to the portable device is mounted, Wherein a first coil of the wireless power transmission unit included in the wireless charging module is disposed on a second surface of the first printed circuit board, A shielding member is disposed between the second surface of the first printed circuit board and the primary coil, and the power supply unit and the control unit of the wireless charging module are disposed at positions corresponding to the power supply unit and the control unit of the beacon module, respectively.

The wireless charging module 110 is a module for wirelessly transmitting power to the
The near field wireless power transmission technique can be classified into a magnetic induction (MI) method, a magnetic resonance (MR) method, and a microwave radiation method. The magnetic induction method is a method of transmitting electric power by using a magnetic field induced between a primary coil (transmission coil) and a secondary coil (receiving coil). The magnetic resonance method uses a resonance phenomenon between the primary coil (transmission coil) connected to the source coil and the secondary coil (reception coil) connected to the device coil to transmit power.
The wireless charging module 110 delivers power wirelessly to one of the illustrated schemes. The wireless charging module 110 includes a
