The invention discloses an undercarriage damping structure for an unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicle parts. The damping device comprises a damping support and an undercarriage, the damping support comprises a damping top plate, a door-shaped bottom frame and a pair of buffering mechanisms, and the damping top plate comprises a lower plate and a protruding plate connected to the upper end of the lower plate; the two sides of the lower plate are in sliding fit with the corresponding side plates of the door-shaped bottom frame respectively, limiting blocks are arranged on the two sides of the upper end of the door-shaped bottom frame respectively, the limiting blocks can limit the corresponding side of the lower plate in the door-shaped bottom frame, an arc-shaped notch is formed in the bottom end of a top plate of the door-shaped bottom frame, and the arc-shaped notch is meshed with a ball joint of the undercarriage; the buffering mechanisms are arranged between the lower plate and the top plate of the door-shaped bottom frame, the outer sides of the buffering mechanisms are connected with the side plates corresponding to the door-shaped bottom frame, and due to the damping support, the door-shaped bottom frame and the pair of buffering mechanisms, when the unmanned aerial vehicle ascends or descends, the impact force generatedby the ground on the unmanned aerial vehicle can be effectively buffered.

    本发明公开了一种无人机用起落架减震结构,属于无人机零部件技术领域。包括减震支架和起落架,其中,减震支架包括避震顶板、门型底架和一对缓冲机构,避震顶板包括下板和连接在下板上端的凸板;下板的两侧分别与门型底架对应的侧板滑动配合,且门型底架的上端的两侧分别设有限位块,限位块能够将下板对应的一侧限定在门型底架内,门型底架的顶板的底端上开设有弧形凹口,弧形凹口与起落架的球关节相咬合;缓冲机构设置在下板与门型底架的顶板之间,且缓冲机构的外侧与门型底架对应的侧板相连,由于本发明的减震支架、门型底架和一对缓冲机构,因而在无人机上升或降落时,本发明能够对地面对无人机产生的冲击力进行有效缓冲。
