POWER SUPPLY APPARATUS

摘要

In the power supply apparatus (100), on an upper surface (202a), which is the surface opposing the power-receiving unit (153) of a cabinet (103b), in the portion where a power supply coil (103a) is projected when the power supply coil (103a) is projected on the cabinet (103b) toward the direction of the power-receiving unit (153), a first inclined part (203) gradually approaching the power supply coil (103a) from the top section (205) toward the inner edge section (211) of the power supply coil (103a) is formed in the radial direction of the power supply coil (103a), and in the portion where the power supply coil (103a) is projected, a second inclined part (204) gradually approaching the power supply coil (103a) from the top section (205) toward the outer periphery (212) of the power supply coil (103a) is formed in the radial direction of the power supply coil (103a).

主权项

1. An electric supply apparatus that contactlessly supplies electric power using electromagnetic induction to an electric reception section provided in a vehicle, the apparatus comprising:
a ring-shaped electric supply coil that faces the electric reception section and that supplies electric power to the electric reception section; and a casing that houses the electric supply coil, wherein the casing includes a first incline portion, a second incline portion, and a recessed portion on an upper surface of the casing, the upper surface being a surface facing the electric reception section: the first incline portion being formed in a portion of the upper surface where the electric supply coil is projected when the electric supply coil is projected on the casing toward the electric reception section, and gradually approaching the electric supply coil from a top portion on the upper surface toward an inner edge portion of the electric supply coil in a radial direction of the electric supply coil; the second incline portion being formed in the portion of the upper surface where the electric supply coil is projected, and gradually approaching the electric supply coil from the top portion toward an outer circumference of the electric supply coil in the radial direction of the electric supply coil; and a recessed portion being in contact with an end portion of the first incline portion located in a direction different from the top portion.
