The invention discloses an unmanned aerial vehicle undercarriage which comprises a mounting plate, a U-shaped rod and a damping device. The damping device comprises a cylinder, a connecting piece, a sliding block, a rubber cap, compression springs and a coil assembly. A limiting plate is arranged in the cylinder, and a cavity is formed in one side of the limiting plate; the sliding block is spherical and is arranged in a mounting cavity in a sliding manner, and a strong magnet is arranged in the sliding block; the compression springs comprise a first compression spring arranged between the sliding block and the limiting plate and a second compression spring arranged above the sliding block. The lower end of the connecting piece is in threaded connection with the upper end of the cylinder.The upper end of the second compression spring makes contact with the lower end face of the connecting piece. The bottom of the rubber cap is fixed with the upper end of the connecting piece. The endof the U-shaped rod sequentially penetrates through the rubber cap, the connecting piece and the second compression spring and then is fixedly connected with the sliding block. The coil assembly is sleeved on the outer side of the cylinder. By the adoption of the novel structure, a good damping effect is achieved, better protection is provided for high-precision equipment on the unmanned aerial vehicle, and carried parts are prevented from being loosened and damaged.
