Launch and withdraw device of unmanned aerial vehicle and method for launch and withdraw device

Abstract

The invention provides a launch and withdraw device of an unmanned aerial vehicle and a method for the launch and withdraw device, and the device comprises a base, wherein the base is connected with a support platform through a support frame; an angle adjustment mechanism is further arranged between the base and the support platform; the support platform is slidingly provided with a withdraw platform and a catapult platform; the catapult platform comprises a second connecting plate; a groove is formed in the second connecting plate; a clamping plate is slidingly connected onto the second connecting plate; a hole is formed in the second connecting plate; an elastic rope passes through the hole to be fixedly connected onto the support platform; the withdraw platform comprises a lower jaw and an upper jaw; the upper jaw is arranged at the upper part of the lower jaw; the upper jaw is provided with a flexible buffer strip; the end, close to the catapult platform, of the lower part of the lower jaw is provided with a hook; the lower jaw is internally provided with a recovery rack; the recovery rack is provided with an unmanned aerial vehicle attitude adjustment mechanism and an unmanned aerial vehicle pushing mechanism; a wedge-shaped block is arranged on the end, close to the catapult platform, of the support platform; a cam corresponding to the hook is arranged on the end, far away from the catapult platform, of the support platform. By adopting the launch and withdraw device of the unmanned aerial vehicle, straight path launch can be realized, the catapult launch efficiency is high, a withdraw process is accurate and stable, and the launch and the withdraw can be realized at the same time.

Description

Technical field: [0001] The invention relates to the technical field of unmanned aerial vehicle control, in particular to an unmanned aerial vehicle launch and recovery device and method thereof. Background technique: [0002] With the development of science and technology, the application of unmanned aerial vehicle is more and more extensive. Unmanned aerial vehicle is referred to as "unmanned aerial vehicle", which is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. There is no cockpit on board, but equipment such as autopilot and program control device are installed. Personnel use radar and other equipment to track, locate and remotely control it. The UAV can be launched and taken off like an ordinary aircraft, it can automatically land and recover like an ordinary aircraft, and it can also be recovered with a parachute or block by remote control. [0003] The launch and recovery of drones are two essential lin...
