Title:
非接触電力伝送装置および送電装置
Document Type and Number:
Japanese Patent JP6909026
Kind Code:
B2
Abstract:
A power transmission device is configured to transmit power to an instrument comprising a first case, a power reception coil arranged to generate an induced current due to magnetic flux in a first direction intersecting a gravitational direction, and a holder configured to hold the power reception coil at a predetermined distance from an outer surface of the first case in the first case, in a noncontact manner. The device comprises a conductive second case, a power transmission coil, and an elastic body. The conductive second case has an opening into which the instrument is inserted and in which the instrument is stored. A power transmission coil is disposed in the second case so as to generate magnetic flux in the first direction, and is arranged to generate an induced current in the power reception coil. The elastic body is disposed in the second case, and is arranged to maintain a distance between the power transmission coil and the power reception coil to be constant, and to support the power transmission coil.
