Vibration reduction type undercarriage of unmanned aerial vehicle

Abstract

The invention discloses a vibration reduction type undercarriage of an unmanned aerial vehicle. The vibration reduction type undercarriage comprises a hydraulic damper installed on the unmanned aerialvehicle, a wheel carrier hinged to a piston rod of the hydraulic damper and movably connected with an aircraft wheel, and a tension spring with the two ends connected with a cylinder body of the hydraulic damper and the wheel carrier correspondingly. Impact borne by all parts of the unmanned aerial vehicle can be greatly damped through the damping structures of the three parts so as to guaranteesafe rising and falling of the unmanned aerial vehicle, the two ends of the tension spring are arranged on the plug pins in a sleeving mode, and therefore the tension spring, the hydraulic damper andthe wheel carrier can be rapidly connected together. During disassembly, the tension spring can be quickly disassembled only by separating the end of the tension spring from a bolt, so that the disassembly and the replacement are convenient and quick. In addition, the bearing range of the undercarriage can be adjusted by replacing different tension springs and hydraulic dampers according to the total weight of the unmanned aerial vehicle, matched bearing is made to be within the permitted range, use is flexible, and the range is wide.

Description

technical field [0001] The invention relates to a landing gear, in particular to a vibration-damping landing gear of an unmanned aerial vehicle. Background technique [0002] The landing gear supports the aircraft when the drone takes off, lands, and taxis on the ground. The main function of the landing gear is to attenuate the shock vibration transmitted by the ground to the UAV. It is a necessary support device for the UAV to take off, land, slide, move on the ground and park. Effectively protect the drone from damage. [0003] The landing gear of the existing unmanned aerial vehicle has the following disadvantages: 1. The existing landing gear only relies on tension springs for vibration reduction. Although this method can play a certain damping effect, it will produce aftershocks of a certain magnitude when the tension springs rebound. Make the UAV in potential danger; 2. The structure design of the damping module of the existing landing gear is relatively complicated,...

[0003] The landing gear of the existing unmanned aerial vehicle has the following disadvantages: 1. The existing landing gear only relies on tension springs for vibration reduction. Although this method can play a certain damping effect, it will produce aftershocks of a certain magnitude when the tension springs rebound. Put the UAV in potential danger; 2. The structure design of the vibration-damping module of the existing landing gear is relatively complicated. When it is damaged, it cannot be quickly disassembled and replaced, and maintenance is troublesome and time-consuming.
