Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a unmanned aerial vehicle charging and disconnecting structure used in an unmanned aerial vehicle hangar. Background Art

[0002] With the rapid development of the Internet and the Internet of Things, drone products have been widely used in many fields in modern society, such as forestry, power grid, sea area, surveying and mapping and other related industries. Drones can complete tasks such as reconnaissance, detection, and inspection. However, a single drone operation system still needs to rely on a lot of personnel to ensure it, and the professional level of the support personnel is required to be high. This means that a single drone operation system has not achieved true unmanned operation. Therefore, a drone operation system that can operate without human participation, that is, a drone hangar system, was born.

[0003] In recent years, drone hangar systems have gradually entered the public's field of vision. Drone hangars refer to drone systems that can automatically return drones to their original positions, store them, maintain them, and charge them. The entire process of drone operations is controlled by the system itself, without the need for human involvement. Currently, drone hangar systems are mainly used for multi-rotor drone hangars, and most of them are consumer-grade drone hangar systems.

[0004] In view of the size, weight and endurance requirements of vertical take-off fixed-wing UAVs, the aerodynamic shape of the aircraft is very important. When the aircraft is used in conjunction with the UAV hangar, the location of the required charging and disconnecting mechanism is very important. It must meet the charging and disconnecting functions and be as small as possible or even not affect the aerodynamic shape. When the UAV lands on the hangar, the charging and disconnecting mechanism often has poor contact with the UAV when charging, resulting in poor charging effect. Utility Model Content
