Tumbler mechanism wireless energy transfer coil device and method capable of resisting lateral deviation

Abstract

The invention provides a tumbler mechanism wireless energy transfer coil device and method capable of resisting lateral deviation. When a first magnetic force control module at a transmitting coil receives the magnetic force of a second magnetic force control module at a receiving coil, a tumbler module for fixing the transmitting coil is driven to deflect by taking the gravity center of the tumbler as an axis, so that the transmitting coil generates angular deflection and position movement to achieve the purpose of tracking of the position of the receiving coil. When the receiving coil is misplaced, the tumbler mechanism wireless energy transfer coil device and method provided by the invention can optimize the relative positions of the transmitting coil and the receiving coil during energy transmission to greatly improve the energy transmission efficiency. The tumbler mechanism wireless energy transfer coil device and method partially overcome the defects that the transmission distance is low and the transmission efficiency is low caused by malposition of the coils and improve the lateral deviation resistance of the wireless power transmission system.
