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.

    本发明提供一种用于无人机无线充电的单电容耦合机构、系统及无人机,耦合机构包括发射端和接收端,发射端设置有上小下大的充电圆台,该充电圆台的侧面通过敷设金属薄膜形成原边发射极板;接收端设置有与充电圆台相互配合的圆台状接收罩,该圆台状接收罩的侧面通过敷设金属薄膜形成副边接收极板;原边发射极板与副边接收极板构成单电容电场耦合机构实行无线充电。在其构成的系统中,发射端还设置有直流电源、逆变器和原边电路拓扑结构,接收端还设置有整流滤波装置和充电电池包。其效果是:结构简单,重量较轻,可极大提升耦合电容值,能利用无人机自身重力修正偏差,提高系统的抗偏移能力,同时可以满足小型无人机频繁切换负载和轻便性的需求。
