The invention discloses an undercarriage facilitating stable rising and falling of an unmanned helicopter, and belongs to the field of unmanned helicopters, an unmanned helicopter fuselage is characterized in that two outer undercarriages and two inner undercarriages are symmetrically arranged on the lower portion of the unmanned helicopter fuselage, and each outer undercarriage comprises a hinge seat and an inclined supporting plate; the hinge seat is fixed to the side face of the unmanned helicopter body, the hinge seat and the inclined supporting plates are installed in a hinged mode through rotating shafts, first anti-skid bottom plates are installed at the bottom ends of the two inclined supporting plates in a hinged mode, the two inner undercarriages comprise fixing plates and anti-impact plates, and the top ends of the fixing plates are fixed to the bottom of the unmanned helicopter body. According to the invention, the outer undercarriage and the inner undercarriage are arranged for primary and secondary buffering, and on the basis, the inclined push plate linked with the inner undercarriage and the buffering mechanism are used for auxiliary supporting of the inner undercarriage, so that the stability of the inner undercarriage 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.

    本发明公开了一种便于无人直升机稳定起落的起落架,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。
