Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless charging apparatus capable of aligning a transceiver, and more particularly, to a wireless charging apparatus capable of aligning a transmitter and a receiver by magnetic force, will be.
Recently, interest in energy-IT convergence technology is increasing. Energy-IT fusion technology is a fusion of IT technology that is rapidly developing into conventional energy technology, and there is Wireless Power Transfer (WPT) technology as a field of such energy-IT fusion technology. The term "wireless power transmission" refers to a technique of supplying power to household electric appliances or electric vehicles wirelessly instead of the conventional wired electric power lines. Conventionally, in order to charge household electric appliances, a power cable, which is wired from a power outlet to an electric appliance or a charger, Related researches have been actively carried out because of the advantage of being able to charge household appliances and the like wirelessly without connection.
Wireless power transmission technologies that are currently being commercialized or researched can be broadly divided into four types. One of them is a high power microwave radiation system. Since this system can transmit high power using a frequency of several GHz band, it can not be commercialized due to problems such as harmfulness to human body and straightness. The other is a radiative short-range transmission method, which uses an RFID / USN frequency band of UHF (Ultra High Frequency)
Band or 2.4 GHz ISM band. Currently, it is commercialized in certain fields such as distribution and logistics fields, and has a disadvantage that it can transmit power of up to several tens of mW due to radiation loss. On the other hand, the contact-type transmission method using inductive coupling is a method of transmitting a few W of electric power by touching at distances of several mm to several centimeters, and uses frequencies such as 125 kHz or 135 kHz. Currently, , Electric toothbrushes, and the like.
The non-radiated magnetic resonance method is based on a resonant coupling method. Here, resonance coupling refers to a phenomenon in which electromagnetic waves move from one medium to another through a near magnetic field when two media resonate at the same frequency in the case of magnetic resonance. Such a non-radiative magnetic resonance method has an advantage that large power transmission of several tens of watts can be performed at a distance of several meters or less.
A technique related to a wireless power charging method capable of charging the
Since the dual capsule endoscope is manufactured to be small enough to be inserted into the inside of the human body, charging by the magnetic resonance method is more effective than charging by a separate charger. The wireless power charging scheme using the magnetic resonance method improves the charging efficiency when the position of the receiver and the transmission period are aligned horizontally.
However, in the conventional magnetic resonance type wireless power transmitting / receiving device, a technique of horizontally aligning a magnetic field in a receiver using a magnet has been proposed. However, for example, there is a wireless power receiver installed in a capsule endoscope inserted into a human body, There is a problem in that the charging efficiency is inferior even if the direction of the magnetic field is matched by using the magnet in the receiver because the position is not matched in the transmission period.
A first object of the present invention to solve such problems is to provide a transmitter and a magnetic body in a reception period so as to selectively align positions of a transmitter and a reception period, And a wireless charging device capable of aligning a transceiver using a magnetic body.
It is a second object of the present invention to provide a wireless charging device capable of reducing the volume of a transmitter and a receiver of a wireless charging device by installing electromagnets in the transmitter and the receiver using electric energy, .
A third object of the present invention is to provide a wireless charging device having a shielding device and capable of aligning a transceiver capable of selectively aligning a position of a transmission / reception period by a magnetic force according to need.
Accordingly, in order to accomplish the first object, the present invention provides a wireless communication system including a controller for controlling transmission of a wireless power signal; A transmitter for transmitting a wireless power signal under the control of the controller; And a receiver for receiving the wireless power signal transmitted from the transmitter and for charging the battery, wherein the transmitter and the receiver are capable of aligning the transceiver having the magnetic body so that the positions are aligned by the magnetic force.
In the above embodiment, the magnetic body is a ferromagnetic substance provided in a shielding portion that can shield an electromagnet or a magnetic force formed by power sources of different polarities supplied to a transmitting antenna and a receiving antenna provided in a transmitter and a receiver.
Therefore, the wireless charging apparatus capable of aligning the transceiver of the present invention has an effect that the transmitter and the receiver can attract each other by the magnetic force by the magnetic body, and the transmitter and the receiver can be horizontally aligned, thereby improving the wireless charging efficiency.
In addition, since the electromagnet is formed by supplying power to the transmitter and the receiver having different polarities, the volume of the wireless charging device can be reduced, and a wireless charging device with a smaller size can be manufactured.
Further, the present invention provides a ferromagnetic body and a shielding device, so that the user can selectively align the position as needed, thereby providing the user with convenience.
