The invention discloses an air-ground amphibious multi-rotor unmanned aerial vehicle, and belongs to the field of unmanned aerial vehicles. The UAV comprises an upper fuselage and a lower fuselage which are fixedly connected in a laminated manner; at least two pairs of arms are symmetrically mounted on the side surface of the upper fuselage about the central axis; arm tips of the arms are rotatably connected with tilting bases, steering engines are further connected between the arms and the tilting bases, the rotating axes of the tilting bases are horizontal and perpendicular to the central axis of the upper fuselage, ducted propellers are fixedly mounted on the tilting bases, and the axes of the ducted propellers are perpendicular to the rotating axes of the tilting bases; at least two pairs of foot stools are symmetrically mounted on the side surface of the lower fuselage about the central axis, and rollers are mounted at the bottom ends of the foot stools; and the foot stools are made of an elastic deformable material, and a combined type spring damping device is further connected between the two foot stools arranged in pairs. The unmanned aerial vehicle can slide on the ground, the impact force during landing can be buffered, the stability of the unmanned aerial vehicle is improved, and airborne electronic equipment is protected.

    本发明公开了一种陆空两栖多旋翼无人机,属于无人机领域,包括以层叠状固定连接的上机身和下机身;上机身的侧面关于中轴线对称安装有至少两对机臂;机臂的臂梢处均可转动连接有倾转底座,机臂与所述倾转底座之间还连接有舵机,倾转底座的转动轴线水平且垂直于上机身的中轴线,倾转底座上均固定安装有涵道螺旋桨,涵道螺旋桨的轴线垂直于倾转底座的转动轴线;下机身的侧面关于中轴线对称安装有至少两对脚架,脚架的底端均安装有滚轮;脚架由弹性可变形材料制造,且成对布置的两个脚架之间还连接有复合式弹簧减震装置。本发明能够使无人机在地面上滑行,还能够缓冲降落时冲击力,提高无人机的稳定性,保护机载电子设备。
