Coupling charging device and system for charging unmanned aerial vehicle

Abstract

The invention provides a coupling charging device and system for charging an unmanned aerial vehicle, transmitting polar plates of a transmitting plate assembly of the device are arranged at intervals, and a cylindrical sleeve type metal polar plate group in a receiving plate assembly sleeves a takeoff and landing cross frame of the unmanned aerial vehicle and is connected with an airborne circuit of the unmanned aerial vehicle to charge the unmanned aerial vehicle; and the grouping control circuit is electrically connected with the transmitting plate assembly, controls the transmitting plate assembly to form two different plate electrode groups, and is electrically connected with a terminal of the excitation source, so that the unmanned aerial vehicle is charged through a coupling electric field formed by the transmitting plate assembly and the receiving plate assembly when the excitation source is in a high-voltage excitation condition. It can be seen that by applying the device, the appearance structure of the unmanned aerial vehicle does not need to be changed, the cost of refitting the appearance of the unmanned aerial vehicle can be avoided, meanwhile, the grouping control circuit can change the free combination of the emitting polar plates, it is ensured that coupling capacitance formed by the unmanned aerial vehicle at different landing positions and in different landing directions is kept constant, and the dislocation tolerance capacity is improved.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a coupling charging device and system for charging drones. Background technique [0002] At present, insufficient endurance and limited cruising range have become an important factor restricting the development of UAVs. In the context of high energy density batteries still unable to obtain breakthrough research progress, wireless charging technology has become an important means to deal with the problem of drone endurance. [0003] In the prior art, although the magnetic field-coupled UAV wireless charging technology can help realize high-power and high-efficiency power transmission, it also has defects such as high cost and heavy weight of the receiving mechanism. In contrast, the electric field coupled UAV wireless charging system only uses metal plates as the coupling mechanism for power transmission, which has obvious advantages such as low cost and light weight of the receiv...
