The invention relates to the field of unmanned aerial vehicle accessories, and discloses a multifunctional protective undercarriage for an unmanned aerial vehicle, which comprises a main supporting frame fixed to the bottom of an unmanned aerial vehicle, a main supporting rod is fixed to the lower side of the main supporting frame, and connecting balls are rotationally arranged on the two sides of the main supporting rod; supporting blocks capable of being detached are symmetrically arranged on the two sides of the main supporting frame, mounting cavities with openings facing the sides close to the main supporting frame are formed in the supporting blocks, mounting assemblies are arranged in the mounting cavities, and limiting cavities are formed in the end walls of the upper side and the lower side of each mounting cavity in a communicating mode. According to the multifunctional protective undercarriage for the unmanned aerial vehicle, when the unmanned aerial vehicle is about to fall into water from the high altitude due to a fault, the unmanned aerial vehicle can stably float on the water surface in the mode that the stabilizing plates are unfolded and the air bags are inflated to be expanded and unfolded, so that the unmanned aerial vehicle is prevented from entering the water; therefore, the problem that the unmanned aerial vehicle is easy to damage when falling into water is solved.

    本发明涉及无人机配件领域,且公开了一种无人机多功能防护起落架,包括固定在无人机底部的主支撑架,所述主支撑架的下侧固定有主支撑杆,所述主支撑杆的两侧转动设置有连接球,所述主支撑架的两侧对称设置有能够进行拆卸的支撑块,所述支撑块内设置有开口朝向靠近主支撑架一侧的安装腔,所述安装腔内设置有安装组件,所述安装腔的上下两侧端壁内连通设置有限位腔。该一种无人机多功能防护起落架能够在无人机出现故障从高空即将坠入水中时,通过展开稳定板和对气囊进行充气使气囊膨胀展开的方式,来使无人机能够稳定漂浮在水面上,从而避免无人机进水,进而解决了无人机掉入水中易损坏的问题。
