Abstract

Provided is a wireless power transmission apparatus for wirelessly transmitting the power to portable electronic appliances using power or batteries charging power and supplying operation power to the portable electronic appliances. The wireless power transmission apparatus includes first and second source resonators, which are included inside a plurality of resonator bodies and which generates and wirelessly transmits the resonant power to a target resonator. The resonator bodies are formed to be folded to each other on an axis of a hinge.

Claims

1. An wireless power transmission apparatus transmitting a resonant power in a magnetic resonance, comprising:

a first source resonator body;

a second source resonator body;

a hinge making the first source resonator body and the second source resonator body be rotated so that the first source resonator body and the second source resonator body face a less power receiving device;

first and second resonator bodies that are foldable with respect to one another on an axis of a hinge; and

first and second source resonators configured to wirelessly transmit power to a target resonator of a wireless power reception apparatus, wherein the first and second source resonators are disposed inside the first and second resonator bodies, respectively, and configured to generate a resonant power according to a power of a predetermined frequency, which is supplied by a resonant controller, wherein the resonant controller alternatively supplies the power of the predetermined frequency to the first and the second resonator, to form a rotating magnetic field around the target resonator so that the target resonator can resonates in a rotational direction of the rotating magnetic field to receive the resonant power,

wherein the resonant controller alternatively supplies the power of the predetermined frequency to the first and the second resonators, to form a rotating magnetic field around the target resonator so that the target resonator can resonates in a rotational direction of the rotating magnetic field to receive the resonant power.

2. The wireless power transmission apparatus of claim 1, further comprising:

a controller body encasing the resonant controller and being configured to engage the first and second resonator bodies to enable the first and second resonator bodies to be foldable with respect to each other by the hinge.

3. The wireless power transmission apparatus of claim 1, wherein the resonant controller alternatively supplies the power of the predetermined frequency to the first and second source resonators.

4. The wireless power transmission apparatus of claim 1, wherein the first and second source resonators respectively comprise:

source coils, which are included inside the first and second resonator bodies, respectively, and to which the power of the predetermined frequency is applied; and

resonant coils, which are included inside the first and second resonator bodies, respectively, and which generate the resonant power by induction of the power of the predetermined frequency applied to the source coils and resonate.
