Embodiment Construction

[0036] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

[0037] The present invention considers that the transmitting coil tracks the offset of the receiving coil, so as to improve the decrease in transmission efficiency caused by misalignment between the transmitting and receiving coils. For this reason, a wireless energy transmission coil device with a tumbler mechanism is proposed. Using the magnetic force and the tumbler mechanism, a transmitting coil structure that can automatically track with the offset of the receiving coil is designed to reduce the attenuation of the coupling coefficient caused by the offset of the coil, and then compare Significantly improve the energy transmission efficiency of the system.

[0038] Such as Figure 4 As shown, the wireless power transmission coil device of the present invention includes: a first magnetic force control module 1 , a seco...

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.

Description

technical field [0001] The invention relates to the technical field of wireless energy transmission, and provides a technical solution for wireless energy transmission adapted to coil misalignment. Background technique [0002] Wireless energy transmission technology has become an ideal technical solution for charging equipment, and has broad application prospects in consumer electronics, medical electronics, and industrial electronics. Magnetic induction coupling and magnetic resonance coupling are currently the most widely used technologies in wireless energy transfer, and they transmit electric energy through the electromagnetic coupling between the transmitting coil and the receiving coil. [0003] The efficiency of wireless power transfer is largely determined by the coupling coefficient between coils. The larger the coupling coefficient, the higher the transmission efficiency. The coupling coefficient between the transceiver coils is affected by many factors such as ...
