Abstract

The invention provides a single-capacitor coupling mechanism and system for wireless charging of an unmanned aerial vehicle and the unmanned aerial vehicle, the coupling mechanism comprises a transmitting end and a receiving end, the transmitting end is provided with a charging circular truncated cone with a small upper part and a large lower part, and the side surface of the charging circular truncated cone forms a primary side transmitting polar plate by laying a metal film; the receiving end is provided with a circular-truncated-cone-shaped receiving cover matched with the charging circular truncated cone, and the side face of the circular-truncated-cone-shaped receiving cover forms a secondary side receiving polar plate by laying a metal film. And the primary side transmitting polar plate and the secondary side receiving polar plate form a single-capacitor electric field coupling mechanism to realize wireless charging. In a system formed by the system, the transmitting end is further provided with a direct-current power supply, an inverter and a primary side circuit topological structure, and the receiving end is further provided with a rectifying and filtering device and a rechargeable battery pack. The single-capacitor coupling mechanism has the advantages that the structure is simple, the weight is light, the coupling capacitance value can be greatly improved, deviation can be corrected through the gravity of the unmanned aerial vehicle, the anti-deviation capacity of the system is improved, and meanwhile the requirements for frequent load switching and portability of the small unmanned aerial vehicle can be met.

Description

technical field

[0001] The invention relates to wireless energy transmission technology, in particular to a single capacitive coupling mechanism and system for wireless charging of drones and drones. Background technique

[0002] An unmanned aircraft is an aircraft that is controlled by radio real-time remote control or its own pre-stored programs, has the ability to carry multiple functional devices to perform various tasks, and can be used multiple times. Aerial Vehicle is abbreviated as UAV).

[0003] Due to the advantages of small size, flexible use, and strong adaptability, UAVs are widely used in surveying, reconnaissance, and early warning, covering scientific research, civil, and military fields. Among the various indicators for evaluating the performance of drones, one of the important indicators is the endurance of drones, and long range is also one of the main development trends of drones in the future. From the energy point of view, there are two main ways to i...
