Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a landing buffer device for an unmanned aerial vehicle. Background Art

[0002] Aircraft refers to aircraft that can fly in the atmosphere. Any aircraft must generate a lift greater than its own weight in order to rise into the air. Based on the principle of generating lift, aircraft can be divided into two categories: lighter-than-air aircraft and heavier-than-air aircraft. The former relies on the static buoyancy of air to rise into the air; the latter relies on aerodynamic force to overcome its own gravity to rise into the air. Aircraft is a large category of aircraft, and refers to any machine that obtains aerodynamic force to rise into the air through the relative movement of the fuselage and the air, that is, not the reaction of air to the ground. Including balloons, airships, airplanes, gliders, gyroplanes, helicopters, flapping-wing aircraft, tilt-rotor aircraft, etc., and unmanned aerial vehicles are also a relatively special category of aircraft.

[0003] When the unmanned aerial vehicle is landing, the plastic hardware landing gear can easily cause the entire unmanned aerial vehicle to overturn due to its rigid collision with the ground, resulting in damage to the wing collision and fracture and the landing gear collision and fracture. The hard landing of the unmanned aerial vehicle itself is also a phenomenon of great loss. It is common for children to operate drones and violently land the aircraft. Utility Model Content
