The invention relates to the related technical field of unmanned aerial vehicle undercarriage processes, in particular to an undercarriage which is arranged on a vehicle body and comprises a main undercarriage and a front undercarriage, the main undercarriage comprises a frame body detachably installed at the bottom of the vehicle body, and first roller structures and the front undercarriage are symmetrically arranged at the end, away from the vehicle body, of the frame body; comprising a supporting column and a piston rod arranged in the supporting column in a sliding mode, and a second roller structure is installed at the end, away from the supporting column, of the piston rod; according to the invention, through the special profile design of the structures on the main undercarriage and the front undercarriage, the ground impact energy during landing and sliding of the aircraft is absorbed by adopting a deformation energy absorption mode, so that the stress concentration on the main undercarriage and the front undercarriage is eliminated, and the safety of the aircraft is improved. The main landing gear and the front landing gear are prevented from being broken or damaged, and the service life of the main landing gear and the front landing gear is prolonged.
本发明涉及无人机起落架工艺相关技术领域,具体是一种起落架,设置在机体上,包括主起落架及前起落架,主起落架,包括架体,可拆卸安装在所述机体底部,所述架体远离所述机体的一端上对称设置有第一滚轮结构,前起落架,包括支柱及滑动设置在所述支柱内的活塞杆,所述活塞杆远离所述支柱的一端上安装有第二滚轮结构;扭力臂,一端转动安装在所述支柱上,另一端与所述活塞杆转动连接,本发明中通过主起落架及前起落架上结构的特殊形面设计,采用变形吸能方式,吸收飞机着陆、滑行时的地面冲击能量,以消除主、前起落架上的应力集中,防止主、前起落架发生断裂或损坏现象,提高了主、前起落架的的使用寿命。
