A four-rotor UAV take-off assisting device

Abstract

The invention discloses a take-off assisting device for a quadrotor unmanned aerial vehicle. The take-off assisting device for the quadrotor unmanned aerial vehicle comprises a shell; a pressure box is fixedly connected to the top of the cavity of the shell; a liquid injection box is in communication with the center of the top of the pressure box; the top end of the liquid injection pipe runs through the top of the shell and extends above the shell; a liquid injection nozzle is in communication with the top end of the liquid injection pipe; a liquid leaking plate is fixedly connected with theinterior of the liquid injection nozzle; a first spring is fixedly connected to the top of the liquid leaking plate; and a sealing ball is movably connected to one position, at the top end of the first spring, in the liquid injection nozzle. The invention relates to the technical field of unmanned aerial vehicles. According to the take-off assisting device for the quadrotor unmanned aerial vehicle, a piston is pressed down by using pressure in the pressure box so as to push the center of an elastic plate by using a pressing rod so that the center of the elastic plate is sunken, the elastic plate cannot clamp a clamping block after the transverse width of the elastic plate is reduced, a first outrigger can be ejected downwards by using the elastic force of a second spring and then the unmanned aerial vehicle can be ejected by using the counter-acting force of the ground; therefore, an effect of assisting the takeoff is achieved and the take-off of the unmanned aerial vehicle is easier.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a four-rotor unmanned aerial vehicle take-off assisting device. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid demand for drones; currently, they are used in aerial photography, agriculture, plant protection, miniature selfies, express transportation, disaster relief, observing wild animals, mon...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a four-rotor UAV take-off assist device, which solves the problem that the man-machine cannot take off easily due to the low height, and when there are weeds on the ground, it is unsafe to take off the UAV. The problem that the wing is easy to hinge to weeds and cause damage
