Abstract

The invention discloses a small unmanned aerial vehicle recovery mechanism, which provides buffer deceleration damping for the recovery process of the unmanned aerial vehicle through a hydraulic damping brake disc. By adjusting the braking pressure of the brake disc, it can provide satisfactory deceleration damping force for drones with different recovery overload requirements. Through the hydraulic actuator, the recovery net support can be automatically folded to facilitate transportation. This mechanism is composed of net body, net body support, hydraulic system, brake device and so on. The invention is suitable for narrow spaces such as mountains, sea islands, and ships, and has the characteristics of low cost, simple operation, convenient use and maintenance, and the like.

Description

technical field [0001] The invention relates to a recovery mechanism for a small unmanned aerial vehicle, which is used to realize the recovery of the small unmanned aerial vehicle. Background technique [0002] At present, the domestic research on the UAV recovery blocking net is mainly to provide damping force through the turbine mechanism. The selection of the damping medium in the turbine mechanism and the design of the turbine blade size directly affect the damping effect. Turbine damping simulation calculation is relatively complicated, and the test cost is relatively high, resulting in relatively high design cost and long design cycle. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a small unmanned aerial vehicle recycling mechanism with low cost, simple operation and convenient maintenance. [0004] The present invention includes following technical solutions: [0005] A small ...
