The invention provides a low-altitude flight unmanned aerial vehicle. The low-altitude flight unmanned aerial vehicle comprises a main body, a supporting arm is fixedly arranged on the outer side of the main body, and a propeller driven by a motor is arranged at the tail end of the supporting arm; an integrated circuit board is arranged in the main body; a center block is arranged at the bottom ofthe body, a bearing arc-shaped strip extending to the position below the supporting arm is arranged on the outer side of the center block, a buffer spring is arranged in the center block, and a roller bead extending to the position below the center block is movably connected to the bottom of the buffer spring; and an air inlet communicated with the cavity is formed in the side face of the main body, and a plurality of sets of air outlet pipes penetrating through the bottom of the main body are evenly arranged in the cavity. According to the low-altitude flying unmanned aerial vehicle, in thetakeoff and landing process of the unmanned aerial vehicle, the contact area between the four sets of bearing arc-shaped strips and the bottom face is uniform, so that the unmanned aerial vehicle is more stable in the takeoff and landing process, and the appearance of the unmanned aerial vehicle cannot deviate; and the air inlet, the cavity and the air outlet pipes form an air channel, so that theinfluence of air resistance on the flight of the unmanned aerial vehicle is effectively reduced.

    本发明提供了一种低空飞行无人机,包括主体,主体外侧固定设置有支撑臂,支撑臂末端设置有由电机驱动的螺旋桨;主体内部设置有集成电路板;主体底部设置有中心块,中心块外侧设置有延伸至支撑臂下方的承重弧形条,中心块内部设置有缓冲弹簧,缓冲弹簧的底部活动连接有延伸至中心块下方的辊珠;主体侧面开设有与空腔相连通的进风口,所述空腔内均匀设置有多组贯穿主体底部的出风管。本发明所述的一种低空飞行无人机,在无人机起飞和降落的过程中,四组承重弧形条与底面的接触面积较为均匀,使无人机在起飞和降落的过程中更加稳定,仪态不会发生偏移;还通过进风口、空腔和出风管形成风通道的方式有效的降低了风阻对无人机飞行时候的影响。
