Ejection rack for unmanned aerial vehicle launching

Abstract

The invention belongs to the technical field of unmanned aerial vehicles and relates to an ejection rack for unmanned aerial vehicle launching. An existing fixing frame cannot be stopped in time, theejection rack is easy to damage and inconvenient to move, and adjustment is too complex and strenuous. In order to solve the above problems, the following scheme is provided. A support frame is included. The supporting frame is composed of two fixing plates which are arranged in parallel. The two ends of each fixing plate are fixed through iron rods. Chain wheels are symmetrically arranged on an inner wall of one end of the supporting frame, ratchet wheel assemblies are arranged on the two sides of the inner wall of the end, away from the chain wheels, in the supporting frame, the edges of thechain wheels are in transmission connection with the ratchet wheel assemblies through chains, driven gears are fixedly connected to the sides, close to the fixing plates, of the chain wheels, and transmission gears are rotatably engaged with the bottoms of the driven gears. The ejection rack has advantages that an unmanned aerial vehicle fixing device can be stopped slowly, collision is prevented, steering movement is performed automatically, and labor is saved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a catapult rack for launching unmanned aerial vehicles. Background technique [0002] There are already a large number of UAV enthusiasts in our country. There are many types of small UAVs. Traditional fixed-wing UAVs usually need external force to take off. Traditional takeoff methods usually use catapults or hand-throwing to take off. When taking off, it needs to be in an open place. When launching, the fixed frame drives the aircraft to move, and when it reaches the end of the track, it separates. [0003] The structure of the traditional UAV ejection frame is too simple. After separation, the fixed frame will continue to move under the inertia of the motor or other power. At this time, it is necessary to set up a blocking device to stop the fixed frame through impact. During the use process, it will cause damage and deformation of the fixing frame, resulting...
