Land launching and recycling trolley of unmanned aerial vehicle

Abstract

The invention provides a land launching and recycling trolley of an unmanned aerial vehicle. The land launching and recycling trolley comprises a trolley body, a platform, lifting mechanisms and a tail fixing device. Vehicle wheels are arranged on the bottom surface of the trolley body, a motor used for driving the vehicle wheels to advance and retreat is arranged in the trolley body, the platform is arranged on the top surface of the trolley body and the width of the platform is greater than a wing span of the unmanned aerial vehicle, and oblique supporting rods fixed with the trolley body are arranged on the two sides of the bottom surface of the platform correspondingly; the lifting mechanisms are arranged on the two sides of the top surface of the platform correspondingly, each lifting mechanism comprises two lifting rods and a cushion block, the bottom ends of each two lifting rods are mutually fixed together and connected with the platform in a movable mode, the top ends of the lifting rods are connected with the cushion blocks, and the top ends of each two lifting rods move in the corresponding cushion block in the opposite direction correspondingly; the tail fixing device comprises a spring arranged on the trolley body and an annular lock fixed at the top end of the spring, the annular lock comprises an upper lock ring and a lower lock ring, and a cover plate is arranged on the end portion of the upper lock ring; and the annular lock and the cover plate are connected through a rotating shaft, and the cover plate can rotate around the axis of the rotating shaft.

Description

technical field [0001] The invention relates to the technical field of UAV auxiliary equipment, in particular to a UAV ground launch and recovery trolley. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and its own program control device. Due to its large wingspan, it is necessary to reduce the structural weight of the aircraft as much as possible. The take-off and landing of UAVs often require the installation of more complex landing gear to achieve safe launch and recovery. The launch methods mainly include taxi take-off, rocket-assisted launch, catapult take-off, hand throw launch, air launch, and vertical take-off. etc.; and the recovery methods mainly include net impact recovery, parachute recovery and self-landing recovery. [0003] For the launch method of ground roll take-off, the UAV uses the thrust of its own engine to accelerate the launch on the runway through the landing gear during ground roll take-off, whic...

AI Technical Summary

Problems solved by technology

[0003] For the launch method of ground roll take-off, the UAV uses the thrust of its own engine to accelerate the launch on the runway through the landing gear during ground roll take-off, which requires less ground supporting equipment and low use cost, but its It needs better ground environment conditions, poor maneuverability, and the landing gear will increase the weight of the aircraft structure, which will reduce the flight performance to a certain extent. For other methods, it is often necessary to set different settings according to different launch and recovery tasks. The device increases the complexity of ground support
