[0002] An unmanned aerial vehicle (UAV) is an aircraft that can perform aerial missions without the need for direct control by a pilot. UAVs are usually controlled by computer systems and can execute preset programs or fly autonomously through navigation systems such as GPS. They can perform a variety of tasks, including reconnaissance, surveillance, photography, search and rescue, and cargo transportation.

[0003] Existing drone landing gear mostly uses carbon fiber composite tube splicing or special-shaped bent plates and bent tubes. The connection between the landing gear and the fixed part of the drone bottom is inconvenient. At the same time, the drone lacks a certain shock absorption and buffering capacity. Under the action of large impact force, it will cause a large recoil force on the landing gear, and in severe cases, it may even cause damage to the drone structure. Utility Model Content
