The invention discloses a surveying and mapping unmanned aerial vehicle undercarriage assembly for surveying and mapping geographic information, and the undercarriage assembly comprises a fixed frame fixed below an unmanned aerial vehicle, a chassis is arranged below the fixed frame, wing plates are rotatably arranged on the periphery of the chassis, a plurality of rectangular holes are formed in the chassis, and third sliding rails are fixed on the inner walls of the two sides of the rectangular holes; a first sliding block is slidably arranged in the third sliding rail, a second spring is connected between the first sliding block and the third sliding rail, an air bag is arranged in the rectangular hole, one end of the air bag is fixed to the inner wall of the rectangular hole, the other end of the air bag is fixed to the first sliding block, and a plurality of inflation devices used for inflating the air bag are fixed to the lower portion of the base plate. According to the undercarriage assembly, a contraction electric cylinder drives a plurality of first racks to be sequentially meshed with corresponding third gears so that wing plates can sequentially rotate to be horizontal, air resistance can be increased, meanwhile, a first connecting rod pushes a push rod on a dynamic air cylinder to move so as to inflate an air bag, and the air resistance is further increased; and the impact force with the ground during landing is reduced.
本发明公开一种测绘地理信息用测绘无人机起落架组件,起落架组件包括固定在无人机下方的固定架,固定架的下方设有底盘,底盘的四周均转动设有翼板,底盘上设有多个矩形孔,矩形孔的两侧内壁均固定有第三滑轨,第三滑轨内滑动设有第一滑块,第一滑块与第三滑轨之间连接有第二弹簧,矩形孔内设置有气囊,气囊的一端固定在矩形孔的内壁,另一端固定在第一滑块上,底盘的下方固定有多个用于气囊充气的充气装置。本发明起落架组件通过收缩电缸带动多个第一齿条依次与对应的第三齿轮啮合使翼板依次转动为水平,能够增加空气阻力,同时第一连接杆推动动气筒上的推杆移动,用于将对气囊进行充气,进一步的增加了空气阻力,减小了着陆时与地面的冲击力。
