[0002] Unmanned aerial vehicle, abbreviated as UAV, is an aircraft controlled by radio remote control equipment and self-contained program control device. UAV is a general term for unmanned aerial vehicles. Compared with general manually piloted aircraft, UAV has the advantages of small size, low cost, easy use, low requirements for combat environment, strong battlefield survivability, etc. UAV is therefore more convenient in performing tasks. UAVs are mainly divided into unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, unmanned paragliders, etc. UAVs are used in aerial photography, agriculture, plant protection, micro selfies, express transportation, disaster relief, wildlife observation, monitoring of infectious diseases, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting and other fields.
[0003] During the landing process of a drone, the drone's bracket is prone to collide with the ground and vibrate. This vibration is transmitted to the drone body, which will damage the drone's internal components in the long run and reduce the drone's service life. Since the drone will be equipped with instruments used for the corresponding tasks during the execution of the mission, such as the surveying and mapping instruments equipped in the surveying and mapping drone, this vibration will be transmitted to the surveying and mapping instruments at the same time as the drone body, which will not only reduce the accuracy of the surveying and mapping instruments but also reduce the service life of the surveying and mapping instruments.
