Empennage folding mechanism of folding-wing unmanned aerial vehicle

Abstract

The invention discloses an empennage folding mechanism of folding-wing unmanned aerial vehicle. The empennage folding mechanism comprises a fixed part, a torsional spring, a fixed part gland and a rotary movable part, the rotary movable part is connected into the fixed part in a sleeved mode, the torsional spring is connected into the rotary movable part in a sleeved mode, one end of the torsionalspring is fixedly connected with the middle of the fixed part, and one end of the rotary movable part is connected with the middle part of the fixed part gland in a penetrating manner. The folding mechanism is simple in structure, convenient to install, small in occupied space, capable of being used when the empennage is rotated and folded along a certain rotating shaft of any plane of the fuselage and wider in application range, in the using process, the empennage can be rapidly unfolded under the torsion effect of the torsion spring, the unfolding efficiency of the empennage is effectivelyimproved, and extra electric losses are avoided.

Description

technical field [0001] The invention relates to a tail folding mechanism of an unmanned aerial vehicle, in particular to an tail folding mechanism of a folding wing unmanned aerial vehicle, which belongs to the technical field of unmanned aerial vehicles. Background technique [0002] At present, the application of drones in society is more and more extensive, and the take-off methods are becoming more and more diversified. Due to the high requirements for the take-off site of taxi take-off and landing drones, vertical take-off and landing, ejection, barrel launch, and aerial UAVs with multiple take-off and landing methods such as throwing and throwing. [0003] In many cases, when performing complex tasks, a single aircraft cannot complete independently, and the idea of ​​​​cluster UAV coordination came into being. The launch methods of cluster UAVs mostly choose tube shooting and air throwing, and this kind of launch method requires UAVs It occupies a small space, and eac...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a tail folding mechanism for a folding-wing UAV to solve the problem that the electric drive proposed in the above background technology can drive the movement of the wing surface by controlling the steering gear or the motor, but the disadvantages are obvious, the deployment speed is relatively slow, and Problems requiring additional battery loss during flight
