Unmanned aerial vehicle undercarriage

Abstract

The invention provides an unmanned aerial vehicle undercarriage. The undercarriage is composed of a plurality of damping structures; and each damping structure comprises an anti-wear plug, a sponge damping column and a foot seat, wherein the upper portion of the foot seat is fixed to an unmanned aerial vehicle rack, the lower portion of the foot seat is of a cavity structure, the upper portion ofthe sponge damping column is embedded into a cavity of the foot seat, the lower portion of the sponge damping column is of a cavity structure, the anti-wear plug is embedded into a cavity of the sponge damping column, and the bottom of the anti-wear plug protrudes out of the bottom surface of the sponge damping column. Due to the structural design of the unmanned aerial vehicle undercarriage, thecharacteristics of buffering and anti-collision, improving the structural bearing capacity of an unmanned aerial vehicle arm, improving the wear resistance of the undercarriage and the like are achieved, and the technical problems that in the prior art, an unmanned aerial vehicle metal undercarriage does not have the capability of buffering and vibration avoiding, and a sponge pad wrapped around the undercarriage is prone to wear are solved.

Description

technical field [0001] The invention relates to the technical field of UAV shape design, in particular to a UAV landing gear design. Background technique [0002] Multi-rotor UAVs have developed rapidly in recent years and have been widely used in the fields of maritime police and border defense, power line inspection, agricultural plant protection, etc. With the continuous increase and refinement of demands in various fields, higher requirements have been put forward for the performance of UAVs. requirements such as safety and reliability. [0003] At present, the landing gear of small multi-rotor drones is mostly made of metal materials, which have a certain structural strength, but most of them do not have the ability to buffer and shock absorb, and cannot achieve the effect of protecting airborne equipment. UAVs with shock-absorbing requirements usually adopt the shock-absorbing method of wrapping the sponge pad outside the landing gear, but the shock-absorbing effect o...
