Problems solved by technology

[0004] In terms of wireless charging for UAVs, most of the researches of domestic and foreign scholars focus on magnetic field coupling. Although wireless charging can be realized, it still has the following disadvantages: 1) The coupling coil and magnetic core of the system increase the weight of the coupling mechanism, and Higher cost; 2) In the working state, the electromagnetic interference to the surrounding environment is relatively large; 3) When there is a metal conductor between or around the magnetic field coupling mechanism, it is easy to cause eddy current loss in the conductor

Embodiment 2

[0049] At present, UAV, as a mobile device with weak battery life, needs to be charged and discharged frequently. During the frequent moving in and out, it may cause damage to the ECPT circuit system. This embodiment aims to propose a new type of wireless charging system for drones based on electric field coupling while meeting the charging requirements of drones. The system selects a suitable coupling mechanism and resonant network to ensure that no excessive voltage and current impacts are generated during the moving in and out of the UAV, and when the UAV moves in, the system can efficiently and stably provide the required power for the load. Power; when the drone is removed, the system can automatically enter standby mode and maintain low power consumption.

[0050] This embodiment provides a UAV wireless charging system based on electric field coupling (Double T UAV ECPT system), including a transmitting circuit and a receiving circuit, and the transmitting circuit includ...

Embodiment 3

Abstract

The invention relates to the technical field of unmanned aerial vehicle wireless charging, and in particular discloses an unmanned aerial vehicle electric field coupling mechanism, a wireless chargingsystem, a platform and an unmanned aerial vehicle. The unmanned aerial vehicle electric field coupling mechanism comprises a transmitting end and a receiving end, the transmitting end comprises a transmitting end upper circular truncated cone and a transmitting end lower circular truncated cone which are separated from each other by a first preset height, and the receiving end comprises a receiving end hollow upper circular truncated cone and a receiving end hollow lower circular truncated cone which are separated from each other by a second preset height; the transmitting end is made of solid insulating materials, the outer side face is covered with first metal foil, the receiving end is made of light insulating materials, and the inner side face is covered with second metal foil. Insulating isolation layers are arranged on the outer surface of the first metal foil or / and the outer surface of the second metal foil. The coupling mechanism can improve the anti-offset capability of thecharging system and reduce the flight power consumption of the unmanned aerial vehicle, the cost is low, too high voltage and current impact is not generated in the moving-in and moving-out processesof the unmanned aerial vehicle, and when metal conductors exist between the coupling mechanisms or around the coupling mechanisms, eddy current loss of the conductors cannot be caused.
