Abstract

The invention discloses an unmanned aerial vehicle deceleration and damping undercarriage. The unmanned aerial vehicle deceleration and damping undercarriage comprises a fuselage installation plate, a steering arm, a flange connecting assembly, a steering shaft, a tension spring, a plurality of bolts, an unmanned aerial vehicle wheel bracket and an unmanned aerial vehicle wheel. The flange connecting assembly is arranged on the fuselage installation plate. The steering shaft is connected to the flange connecting assembly in an insertion mode. The steering arm is fixedly connected to the steering shaft through the bolts. The steering shaft is fixedly connected to the unmanned aerial vehicle wheel bracket through the bolts. The unmanned aerial vehicle wheel is arranged on the unmanned aerial vehicle wheel bracket. One end of the tension spring is fixedly connected to the steering shaft, and the other end of the tension spring is fixedly connected to the unmanned aerial vehicle wheel bracket. According to the unmanned aerial vehicle deceleration and damping undercarriage, the lever principle is applied, and the upward pressure of the unmanned aerial vehicle wheel is buffered through the tension spring; when the pressure exceeds the tensile force of the tension spring, the tension spring pulls the steering shaft to move downwards; and the lower end of the steering shaft which is pressed to be low is lower than the bottom of the unmanned aerial vehicle wheel and in direct friction with the ground, so that a deceleration effect is achieved, and the landing run distance is greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of landing gear for unmanned aerial vehicles, and in particular relates to a decelerating and shock-absorbing landing gear for unmanned aerial vehicles. Background technique [0002] UAV is an unmanned flying device controlled by radio remote control equipment and self-contained program control device. UAV has the advantages of small size, low cost and convenient use. At present, drones are widely used in aerial photography, agricultural plant protection, surveying and mapping and other fields. The UAVs used in aerial surveys are special types of UAVs. This kind of UAVs has a large load capacity and a long flight time. The main working place is mountainous or high-altitude areas. The aerial survey UAV generally adopts the flight mode of skid lift and landing during the take-off and landing process. During the take-off and landing process, the UAV landing gear is an important device in the process of aircraf...
