Abstract

The invention discloses a UAV charging device based on magnetic coupling wireless power transmission. The UAV charging device comprises a wireless charging module and an energy receiving module installed in an UAV. The wireless charging module comprises a rectifying and filtering circuit, a high-frequency inverter circuit, a transmitting coil, and a relay coil which are connected successively. The relay coil is located in the plane of the transmitting coil and has an axis coinciding with the axis of the transmitting coil. The energy receiving module comprises a receiving coil, a rectifying and voltage stabilizing circuit and a power supply control circuit which are connected successively. The power supply control circuit is connected with a rechargeable battery. The relay coil and the receiving coil have the same size. The wireless charging module and the energy receiving module transmit energy through electromagnetic resonance generated between the relay coil and the receiving coil. The UAV charging device does not need manual charging, can enable the UAV to automatically return and automatically identify and search the wireless charging module when the power of the rechargeable battery is insufficient in order to accurately land to be charged, and greatly improves the using efficiency and the application fields of the UAV.

Description

technical field [0001] The invention relates to the technical field of unmanned aircraft product manufacturing, in particular to an unmanned aerial vehicle charging device based on magnetic coupling wireless power transmission technology. Background technique [0002] Since the invention of multi-axis unmanned aerial vehicles, its advantages of easy control, less difficult flight, stronger stability, and wider application range have attracted widespread attention. Has great potential. However, restricted by the development of battery technology, the problem of shorter flight time compared with fixed-wing aircraft is very prominent. Most of the existing multi-rotor UAV charging technologies adopt the mode of battery replacement. Due to structural design and other reasons, the charging steps are relatively cumbersome, and frequent docking is likely to affect the reliability of the system. Dirt will lead to poor contact or electrical connection failure; if it is in a humid o...
