Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an autonomous charging device for unmanned aerial vehicles. Background Art

[0002] Unmanned aerial vehicles, referred to as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. Drones are actually a general term for unmanned aerial vehicles. From a technical point of view, they can be divided into several categories: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, and unmanned paragliders. After the use of the drone, the drone needs to be charged using a wireless charging device that allows the drone to park autonomously.

[0003] Drones have played a very good application effect in indoor inspections. While greatly improving the inspection efficiency and inspection quality, they have greatly reduced operation risks and labor intensity. They are a good helper for power inspections. However, the batteries of drones must be fully charged to operate normally, and they need to be charged frequently in actual use. When charging, the charging connector and charger must be connected manually, and someone is required to be on duty, which wastes manpower and material resources. In addition, the existing drone charging devices are not easy to move, which reduces the applicability of the device. Therefore, it is necessary to improve the existing devices to meet actual needs.
