Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a shock absorbing device carried on an UAV and having a real-time dynamic positioning function. Background Art

[0002] A drone is an aircraft that can be remotely controlled or flown autonomously. A drone is an autonomous system capable of performing tasks without human intervention. There are many different types of drones and their applications include reconnaissance, surveillance, traffic control, firefighting, agriculture, and entertainment.

[0003] However, the existing technology for drones also has the disadvantage of being difficult to improve the landing stability of the drone. When in use, the bottom of the drone is easily unstable when landing on the ground, and there is no cushioning, which causes the drone to roll over and be damaged. Moreover, the existing technology for drones also has the disadvantage of being difficult to improve the service life of the locator. When in use, rainwater falls on the surface of the locator on rainy days, which easily causes it to age, resulting in a reduction in the service life of the locator. Utility Model Content
