The invention discloses a stable anti-seismic undercarriage for a fixed-wing aircraft, and relates to the technical field of unmanned aerial vehicle undercarriages. For improving a damping effect, theundercarriage specifically comprises a first mounting base, a second mounting base and a buffer chamber, the first mounting base and the second mounting base are mounted on a machine body through a first mounting shaft and a second mounting shaft correspondingly, a fixing rod is integrally arranged on the outer wall of the bottom of the first mounting base, and an electric telescopic rod is fixedto the outer wall of one side of the second mounting base through screws; the output end of the electric telescopic rod is rotationally connected to the outer wall of one side of the fixing rod through a rotating shaft. By arranging a metal plug body, a rubber layer, an annular sealing ring and other structures, the buffering and damping effects can be achieved by compressing air on the top of the buffering chamber, in addition, due to the fact that the number of the pressure relief holes distributed in the annular sealing ring is sequentially decreased in the vertical direction, the effect that the reaction force on the metal plug body is gradually increased can be achieved, and stable cushioning is realized.

    本发明公开了一种固定翼式飞机用的稳固抗震型起落架,涉及无人机起落架技术领域;为了提升减震效果;具体包括第一安装座、第二安装座和缓冲室,所述第一安装座和第二安装座分别通过第一安装轴和第二安装轴安装于机体上,第一安装座底部外壁一体式设置有固定杆,第二安装座一侧外壁通过螺丝固定有电动伸缩杆,电动伸缩杆的输出端通过转动轴转动连接于固定杆一侧外壁。本发明通过设置金属塞体、橡胶层、环形密封圈等结构,能够通过压缩缓冲室顶部空气,达到缓冲减震的效果,此外,由于泄压孔在环形密封圈上分布的数量沿竖直向上方向依次递减,因此能够达到对金属塞体的反作用力逐步提升的效果,实现平稳的缓冲减震。
