Abstract
A shield member and a power transmission unit each include a shielding wall formed annularly about an axis so as to surround a power transmission coil at a position extending along an intersecting direction. The shielding wall shields a magnetic force generated by the power transmission coil. The shielding wall is formed such that a distance between wall faces facing each other in the intersecting direction is wider at a longer distance from a first side toward a second side in an axial direction.
Claims8
A shield member comprising:
- a shielding wall that is formed annularly around a longitudinal axis, and shields a magnetic force generated by a power transmission coil disposed inside the shielding wall, wherein
- the shielding wall includes wall faces facing each other in an intersecting direction that intersects the longitudinal axis,
- the wall faces shield a magnetic force generated by the power transmission coil and are formed such that a distance between the wall faces on a first side of the shielding wall than a distance on a second side of the shielding wall in the longitudinal axis.
A power transmission unit, comprising:
- a power transmission coil that transmits electric power to a counterpart side power transmission coil in a non-contact manner;
- and
- a shield member that includes a shielding wall that is formed annularly around a longitudinal axis, and shields a magnetic force generated by the power transmission coil disposed inside the shielding wall, wherein
- the shielding wall includes wall faces facing each other in an intersecting direction that intersects the longitudinal axis,
- the wall faces shield a magnetic force generated by the power transmission coil and are formed such that a distance between the wall faces on a first side of the shielding wall than a distance on a second side of the shielding wall in the longitudinal axis.
