Abstract

The invention relates to a damping undercarriage of a quadrotor, and belongs to an unmanned plane undercarriage with damping function. According to the damping undercarriage, a support is utilized for fixing a motor, the motor drives two belts to make transmission along different directions through a group of gears, and further drives the undercarriage to deploy and retract through the belts. The undercarriage is hinged with a fastening connector, and the upper end of the undercarriage is connected with the fastening connector via an extension spring. The undercarriage comprises an upper arm and a lower arm which are in connection via s crossbeam and are respectively inside provided with springs. The advantages comprise that the damping undercarriage is novel in structure, can be deployed and retracted according to flight states, reduces air resistance in the flight process, and substantially improve the stability of an unmanned plane. In landing process, the undercarriage is telescopic, the shock loading coefficient is reduced, and the safety of the unmanned plane is improved.

Description

technical field [0001] The invention belongs to a landing gear of an unmanned aerial vehicle with a shock-absorbing function, and specifically relates to a landing gear with a freely retractable and telescopic function, which is mainly used for reducing resistance during flight and slowing down the impact of the ground on the fuselage during descent force. Background technique [0002] Quadrotor UAV is a kind of miniature UAV, which is popular because of its advantages of high flexibility, strong stability, simple operation and low cost. However, the current four-rotor UAVs increase the resistance due to their fixed landing gear when flying in the air. In addition, when landing, the ground will cause a strong rigid impact on the fuselage. In this regard, four-rotors have no Human-machine still faces great challenges. Contents of the invention [0003] The invention provides a shock-absorbing landing gear of a four-axis aircraft to solve the problems of flight resistance ...
