[0002] Unmanned aerial vehicle, also known as UAV, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or operated completely or intermittently autonomously by an on-board computer. Compared with manned aircraft, it has the advantages of small size, low cost, easy use, low requirements for the combat environment, and strong battlefield survivability.

[0003] According to a shock absorbing device for landing gear for unmanned aerial vehicles disclosed on the patent website (authorization announcement number: CN213384690U), "the utility model belongs to the technical field of unmanned aerial vehicles, and in particular, it is a shock absorbing device for landing gear for unmanned aerial vehicles, including an unmanned aerial vehicle body, a rotating shaft is arranged on the surface of the unmanned aerial vehicle body, a propeller is arranged on the surface of the rotating shaft, and a fixing ring is arranged on the top of the rotating shaft. When the unmanned aerial vehicle lands, the weight of the unmanned aerial vehicle when falling is reduced by the second spring arranged inside the telescopic cylinder, so that when the unmanned aerial vehicle lands, the second spring will reduce the diving force generated by the fuselage of the unmanned aerial vehicle under the action of gravity, thereby reducing the impact force generated by the unmanned aerial vehicle when landing on the ground, preventing the fuselage of the unmanned aerial vehicle from being damaged, thereby increasing the service life. At the same time, the first spring is arranged on the surface of the support column to reduce the gravity of the unmanned aerial vehicle falling, thereby sharing the vibration and impact force generated by the unmanned aerial vehicle on the second spring when falling, thereby protecting the second spring and increasing the service life of the second spring."
