Anti-falling structure for oblique photogrammetry unmanned aerial vehicle

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and in particular, relates to an anti-falling structure for an oblique photogrammetry unmanned aerial vehicle, wherein the anti-falling structure comprises a buffer box; a connecting hole is formed in the buffer box, a connecting bolt is inserted in the connecting hole, a spring is sleeved on the connecting bolt, an air bag groove is formed in the buffer box, and an air bag is inserted in the air bag groove. According to the technical scheme, the buffer box is in threaded connection with an aircraft body, and when an aircraft falls and touches the ground, rolling wheels are squeezed by the aircraft body and move outwards; meanwhile, an eccentric wheel is jacked upwards, and the air bag on the buffer box can be jacked out of the air bag groove to make contact with the aircraft body, so that the buffering effect can be achieved to a great extent, and the aircraft body is protected; and when the connecting bolt is extruded by the aircraft body, the connecting bolt moves downwards, so that a spring on the bolt is extruded and compressed, and the downward impact force of the aircraft body can be buffered, so that an auxiliary buffering effect is achieved, the buffering device is protected, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an anti-fall structure for inclined photogrammetry unmanned aerial vehicles. Background technique [0002] With the development of science and technology, the application of drones is becoming more and more extensive, and drones can be seen in various fields. In photography operations, in order to capture beautiful scenery from various angles, the help of drones is indispensable. , but in some news, it is often seen that the UAV has control problems and falls. Once it falls, it means that the UAV is damaged. The manufacturing cost of the UAV is very high. It will bring huge economic losses. Under the existing technology, in order to prevent the crash of the UAV, it is often added a parachute to the UAV, and the speed reactor is used to control the opening of the parachute, but even so, there will be A certain damage to the bottom of the fuselage will also bring ...
