Unmanned aerial vehicle landing shock-proof device utilizing gear transmission principle

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and discloses an unmanned aerial vehicle landing shock-proof device utilizing the gear transmission principle. The device comprises a first shell and a second shell, an air bag is movably connected to the exterior of the first shell, a first spring is movably connected into the first shell, a connecting rod is movably connected to the exterior of the first spring, a toothed rod is movably connected to the end, away from the first spring, of the connecting rod, a ratchet wheel is movably connected into the second shell, afirst gear is movably connected to the exterior of the ratchet wheel, and a spring strip is movably connected to the exterior of the first gear. Under the interaction of the first shell, the second shell, the air bag, the first spring, the connecting rod and the toothed rod, vibration during landing can be absorbed through movement deformation of the first spring during landing of the unmanned aerial vehicle, collision between a vehicle body and the ground during landing of the unmanned aerial vehicle is avoided, transmission between structures can provide a power source for later air bag buffering and shock absorption, so the unmanned aerial vehicle better conforms to use of actual conditions.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a landing shock absorber for drones using the principle of gear transmission. 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. [0003] 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 needs of drones; the current applications in the fields of aerial photography, agriculture, plant protection, miniature selfies, etc. have greatly expanded the use of drones themse...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a UAV landing shock absorber using the gear transmission principle, which has the advantages of shock absorption and stable landing, and solves the problem that the UAV is affected by the quality of its fuselage. During the process, the UAV needs to land from a higher altitude, so that the landing will often be unstable, which may cause collisions between the UAV fuselage and the ground and other landing sites. The more protruding parts of the man-machine collide with the ground, such as the wings. Damage to the wings will make the drone unable to fly again. Even if it can fly, the flight direction may be difficult to be controlled by the operator. question
