Unmanned aerial vehicle undercarriage

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 prob
