Take-off assistance device for unmanned aerial vehicle

Abstract

The invention relates to the related technical field of unmanned aerial vehicles, and particularly relates to a take-off assistance device of an unmanned aerial vehicle which is used for providing take-off pushing force for the unmanned aerial vehicle. The take-off assistance device of the unmanned aerial vehicle comprises a base, a bearing seat, an ejection device and an adjusting mechanism, wherein the bearing seat is mounted on the base; the ejection device is hinged to the bearing seat; the adjusting mechanism is mounted on the bearing seat, is connected with the ejection device and is used for adjusting the rotating angle of the ejection device relative to the bearing seat; the ejection device comprises a guide rail hinged to the bearing seat and a bearing assembly which is installedon the guide rail in a sliding mode and connected with the guide rail through an elastic assembly, and the bearing assembly conducts movement limiting through a clamping and placing assembly arrangedon the guide rail; a pushing assembly is installed on the bearing assembly in a sliding mode, and the pushing assembly and a locking mechanism arranged on the bearing assembly conduct force storage limiting on the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field related to unmanned aerial vehicles, in particular to an auxiliary device for unmanned aerial vehicles to take off. Background technique [0002] Unmanned aircraft, referred to as UAV, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but it is equipped with autopilot, program control device and other equipment. Or the personnel at the remote control station of the parent aircraft can track, locate, remote control, telemetry and digital transmission through radar and other equipment, and can take off like an ordinary aircraft under radio remote control or launch it into the air with a booster rocket, or it can be brought into the air by the parent aircraft. flight. [0003] Existing small UAVs are widely used in daily life, but they also encounter some problems during use. Most of the take-off devices for launching UAVs use...

AI Technical Summary

Problems solved by technology

[0004] However, during the ejection process of the existing UAV ejection device, the ejection stroke is short, and only a single ejection can be performed under the action of the spring, and the degree of assistance for UAVs with higher starting speed requirements is poor.
