Abstract

The invention discloses an induction power take hook applicable to a micro unmanned aerial vehicle and relates to the technical field of electromechanical design. The induction power take hook comprises a connecting rod mechanism, a driving system and a control system. By reasonable design, the connecting rod mechanism can realize that the unmanned aerial vehicle can be hooked on a power transmission line to acquire power, the driving system is used for driving the connecting rod mechanism to fold and unfold, and the control system is used for controlling the working status of the driving system. By the foldable design, the induction power take hook can be folded at ordinary times and unfolded in use, and accordingly flight resistance is reduced beneficially; automatic hooking action and gravity-based self-locking can be realized. Meanwhile, the induction power take hook is compact and simple in structure, and structural weight is reduced beneficially. The unmanned aerial vehicle is supplemented with energy from the power transmission line through induction power take, and an airborne mission system can work normally; the connecting rod mechanism can be extended independently for use, and the capability of largely capturing the target power transmission line is realized.

Description

technical field [0001] The invention relates to the field of electromechanical design, in particular to an inductive power-taking hook suitable for micro-miniature unmanned aerial vehicles. Background technique [0002] At present, unmanned aerial vehicle systems are playing an increasingly important role in both civilian and military fields. Among them, micro-miniature drones refer to drones with a maximum take-off weight of less than 50kg. Due to their small size and light weight, micro-miniature drones have the advantages of easy portability, simple take-off and landing. In use, according to the requirements of the task, the UAV is usually required to have a higher battery life or a longer flight distance. However, due to the limited amount of energy carried by the UAV itself, micro-UAVs face problems such as short battery life and small flight distance, which limit their further wide application. [0003] Therefore, it is very necessary to try to improve the flight tim...
