The invention discloses a high-stability undercarriage for an unmanned helicopter, and belongs to the field of unmanned helicopters. Two outer undercarriages and two inner undercarriages are symmetrically arranged on the lower portion of an unmanned helicopter fuselage, each of the outer undercarriages comprises a hinge seat and an inclined supporting plate, the hinge seat is fixed to the side face of the unmanned helicopter fuselage, the hinge seat and the inclined supporting plate are installed in a hinged mode through a rotating shaft, a first anti-skid bottom plate is installed at the bottom ends of the two inclined supporting plates in a hinged mode, each of the two inner undercarriages comprises a fixing plate and an anti-impact plate, and the top end of the fixing plate is fixed to the bottom of the unmanned helicopter fuselage. According to the invention, the outer undercarriages and the inner undercarriages are arranged for primary and secondary buffering, and on the basis, inclined push plates and a buffering mechanism which are linked with the inner undercarriages are used for auxiliary supporting for the inner undercarriages, so that the stability of the inner undercarriages is improved, the buffering effect is improved, the unmanned helicopter is ensured to be stable and shake-free in the landing process, and safety accidents are avoided.

    本发明公开了一种无人直升机用稳定性高的起落架,属于无人直升机领域,无人直升机机身,所述无人直升机机身的下部对称设有两个外起落架和两个内起落架,两个所述外起落架均包括铰接座和斜撑板,所述铰接座与无人直升机机身的侧面固定,所述铰接座与斜撑板通过转轴铰接安装,两个所述斜撑板的底端均铰接安装有第一防滑底板,两个所述内起落架均包括固定板和抗冲击板,所述固定板的顶端与无人直升机机身的底部固定。本发明通过设置外起落架和内起落架进行初次和二次缓冲,并在上述基础上利用与内起落架联动的斜推板和缓冲机构对内起落架辅助支撑,增加内起落架的稳定性,提升了缓冲效果,确保无人直升机起落过程平稳无晃动,避免安全事故。
