Abstract

The invention discloses a decelerating and shock-absorbing undercarriage for an unmanned aerial vehicle, which comprises a fuselage mounting plate, a steering arm, a flange connection assembly, a steering shaft, a tension spring, several bolts, a wheel bracket and a wheel. The flange connection assembly is arranged on the fuselage mounting plate, and the steering shaft is plugged on the flange connection assembly. The steering arm is fixedly connected to the steering shaft by bolts, and the steering shaft is fixedly connected to the wheel bracket by bolts. The wheel bracket is provided with a wheel, and one end of the extension spring is fixedly connected to the steering shaft, and the other end is fixedly connected to the wheel bracket. In this case, the principle of leverage is used to make the tension spring buffer the upward pressure of the wheel. When the pressure exceeds the tension of the tension spring, the tension spring will pull the steering shaft to move downward, and the lower end of the depressed steering shaft will be lower than the bottom of the wheel and directly rub against the ground. , so as to play a role in deceleration, greatly shortening the landing roll distance.

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...
