Unmanned aerial vehicle charging system

The invention relates to an unmanned aerial vehicle (UAV) charging system. The UAV charging system includes a main UAV and an energy UAV, wherein the main UAV and the energy UAV have electric propulsion powered by a rechargeable battery. The energy UAV battery has a relatively greater capacity than the main UAV battery, and the energy UAV includes a charging element connected at one end to the battery charger and having a charging connector at the other end. The primary UAV has a complementary connector for connection to the charging connector. The system also includes a guidance controller that controls movement of the UAV and, when desired, moves the UAV to a charging position where the charging connector engages the complementary connector and charges the primary UAV battery from the energy UAV battery by the charging system. 本发明涉及无人航空器(UAV)充电系统。UAV充电系统包括主UAV和能量UAV，其中主UAV和能量UAV具有由可再充电电池供电的电推进。能量UAV电池具有比主UAV电池相对更大的容量，并且能量UAV包括充电元件，该充电元件在一端连接到电池充电器，并且在另一端处具有充电连接器。主UAV具有用于连接到充电连接器的互补连接器。系统还包括引导控制器，其控制UAV的移动，并
