COIL UNIT AND CONTACTLESS POWER SUPPLYING APPARATUS

摘要

In a power supplying side core around which a power supplying side resonant coil is wound that contactlessly supplies power to a power receiving side resonant coil, a pair of protrusion portions is provided that protrudes from central axis direction both sides of the power supplying side resonant coil toward the power receiving side resonant coil. Further, in a power receiving side core around which the power receiving side resonant coil is wound that contactlessly receives power from the power supplying side resonant coil, a pair of protrusion portions is provided that protrudes from central axis direction both sides of the power receiving side resonant coil toward the power supplying side resonant coil.

主权项

1. A coil unit comprising a coil that performs contactless power supplying with another coil, and a core around which the coil is wound, a central axis of the coil being disposed to be vertical to a separation direction of the other coil and the coil at a time of the power supplying,
wherein the core is provided with a pair of protrusion portions that protrudes from central axis direction both sides of the coil toward the other coil, wherein the core is provided to be divided into a center portion around which the coil is wound and both end portions respectively provided with the pair of protrusion portions, wherein the core is divided such that the both end portions are overlapped with respective end surfaces of the central axis direction both sides of the coil of the center portion, and wherein protrusion amounts of the pair of protrusion portions are adjusted depending on an inclination of the other coil.
