The invention discloses a passenger plane lengthened main undercarriage staggered structure and a folding method thereof.The passenger plane lengthened main undercarriage staggered structure comprises a plate body installed in a cabin, the plate body is provided with at least two turnover mechanisms, the output ends of the turnover mechanisms are sleeved with connecting rods, the axial ends of the connecting rods extend out of the cabin and are fixedly provided with rod bodies, groove bodies are formed in the lower end faces of the rod bodies, rotating shafts are arranged in the groove bodies, rotating rods are hinged to the rotating shafts, damping mechanisms are fixed to ends of the rotating rods and comprise damping cylinders connected to the rotating rods, tilt angle sensors are fixed to the damping cylinders, bearing mechanisms are arranged in the damping cylinders, the bearing mechanisms comprise lengthened undercarriages arranged in the damping cylinders, and pulleys are fixed to the lengthened undercarriages. The problem that certain potential safety hazards exist due to the fact that an existing passenger plane undercarriage is short in length and a plane body and wings are close to the ground is solved.

    本发明公开了一种客机加长主起落架交错式结构及其收起方法,包括安装在机舱内的板体,所述板体上设有至少两个翻转机构,所述翻转机构的输出端套设有连接杆,所述连接杆轴向的一端延伸至所述机舱外并固定有杆体,所述杆体的下端面开设有槽体,所述槽体内设有转轴,所述转轴上铰接有转动杆,所述转动杆的一端固定有减震机构,所述减震机构包括连接在所述转动杆上的减震筒,所述减震筒上固定有倾角传感器,所述减震筒内设有承载机构,所述承载机构包括设置在所述减震筒内的加长起落架,所述加长起落架上固定有滑轮。解决了现有的客机起落架长度较短,机身与机翼距离地面距离较近,导致存在着一定安全隐患的问题。
