Title:
WIRELESS POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2015231329
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a wireless power transmission device.SOLUTION: A wireless power transmission device according to an embodiment includes: a transmission coil configured to change a magnetic field in response to an AC current; a shielding unit configured to restrict radio waves of the magnetic field generated from the transmission coil; and a case configured to surround the transmission coil and the shielding unit. The transmission coil is formed in a single layer by winding a wire along the sides of an isosceles triangle having a height greater than a base in the same plane. The transmission coil may have an outside height of 52±0.5 mm, an inside height of 34±0.5 mm, an outside width of 46±0.5 mm, an inside width of 28±0.5 mm, and a thickness of 1.1±0.3 mm. The transmission coil may be formed by winding the wire on the sides or the like of the isosceles triangle eight times.
