Power supply system and power supply method for transport vehicles

Abstract

To provide a power supply system and a power supply method of a transport vehicle capable of performing a stable contactless power supply to the transport vehicle without being affected by foreign matters or the like.SOLUTION: A power supply system for a transport vehicle that supplies power to the transport vehicle in a contactless manner includes: a power supply unit that is installed in an upright position for a horizontal surface and supplies power to the transport vehicle; and a power receiving unit that is provided to the transport vehicle when it is in the upright position for the horizontal surface and performs reception of power from the power supply unit when it is in a position facing the power supply unit.SELECTED DRAWING: Figure 1

Claims

1. A power supply system for transport vehicles that supplies power to transport vehicles in a non-contact manner, A power supply unit is installed in an upright position relative to the horizontal plane and supplies power to the transport vehicle, A power receiving unit is provided on the transport vehicle in an upright position relative to the horizontal plane and, when positioned opposite the power supply unit, receives power supplied from the power supply unit. The power receiving unit is provided with a spacing adjustment unit that adjusts the distance between the power supply unit and the power receiving unit when the power supply unit and the power receiving unit are in opposing positions, The spacing adjustment unit is provided on the opposite side of the power supply unit from the power supply unit when the power supply unit and the power receiving unit are in opposing positions, and includes an elastic member that applies pressure in a direction that brings the power receiving unit closer to the power supply unit, and a spacer member that extends from the power receiving unit toward the power supply unit and separates the power receiving unit and the power supply unit. The elastic member is a spring member, and the spacer member has a guide wheel at its tip that can rotate along the direction of travel of the transport vehicle. The system further includes a guide member for positioning the guide wheel in the vertical direction. Power supply system for transport vehicles.
