The invention relates to an air bag type unmanned aerial vehicle falling protection device which is suitable for a four-rotor unmanned aerial vehicle. The protection device comprises a cross protection frame, a control system and an air bag system. The cross protection frame comprises four protection arms; a gas cylinder bin used for containing a gas cylinder is arranged on each protection arm in the axis direction of the protection arm; the control system comprises a steering engine, a cross-shaped control frame and a rectangular sliding block; the cross-shaped control frame comprises four rocker arms; the air bag system comprises an air bag, an air bottle and an inflation spring. When the unmanned aerial vehicle falls, the unmanned aerial vehicle body is wrapped in all directions through the air bag which is rapidly inflated and expanded, the unmanned aerial vehicle falls to the ground through multiple buffering of the air bag, the damage possibility and degree of the unmanned aerial vehicle body are reduced, the unmanned aerial vehicle floats through the air bag when falling to a water area, equipment is prevented from being soaked in water, and the unmanned aerial vehicle can be repeatedly used by replacing an air bottle and folding the air bag.

    本发明涉及一种气囊式无人机坠落保护装置,适用于四旋翼无人机。保护装置包括十字保护架、控制系统和气囊系统;十字保护架包括四个保护臂;每个保护臂上沿其轴线方向均设有一用于容纳气瓶的气瓶仓;控制系统包括舵机、十字控制架和矩形滑块;十字控制架包括四个摇臂;气囊系统包括气囊、气瓶和充气弹簧。本发明通过快速充气膨胀的气囊在无人机坠落时,将无人机主体全方位包裹,无人机坠落地面时依靠气囊多次缓冲,降低无人机主体损坏的可能性和程度,落入水域时依靠气囊漂浮,避免设备浸水,可以通过更换气瓶和折叠气囊重复使用。
