Abstract
In the power transmission unit, a first coil pattern includes first inner side patterns, and first outer side patterns provided on the outer side of the first inner side patterns. A second coil pattern includes second inner side patterns, and second outer side patterns provided on the outer side of the second inner side patterns. The first and second coil patterns are configured such that the first inner side patterns and the second outer side pattern are connected, and the first outer side patterns and the second inner side patterns are connected. Then, the first and second coil patterns transfer power to the power transmission coil pattern of a power receiving unit in a contactless manner.
Claims4
A power transmission unit, comprising:
- a substrate configured to include:
- a first layer that includes a first base material formed in a flat shape and a first coil pattern formed in the first base material in a spiral shape about an axis line;
- and
- a second layer that includes a second base material formed in a flat shape and a second coil pattern formed in the second base material in a spiral shape about the axis line, and is stacked in the first layer, wherein
- the first coil pattern includes a first inner side pattern, and a first outer side pattern provided on an outer side of the first inner side pattern,
- the second coil pattern includes a second inner side pattern, and a second outer side pattern provided on an outer side of the second inner side pattern, and
- the first coil pattern and the second coil pattern are configured such that the first inner side pattern and the second outer side pattern are connected, and the first outer side pattern and the second inner side pattern are connected, and transfer power to a counterpart power transmission coil pattern in a contactless manner.
