The invention relates to a memory alloy planet detection lander based on a negative poisson ratio structure. The memory alloy planet detection lander comprises a lander body and a buffer structure. The lander body is used for containing effective loads, and the buffer structures are connected with the side wall of the lander body at equal intervals in the circumferential direction. The buffer structure comprises a mechanical leg assembly, a main shock absorber and a foot pad. The mechanical leg assembly comprises a landing leg which is made of memory alloy of a negative poisson ratio structure. One end of the main shock absorber is connected with the lander body, and the other end of the main shock absorber is hinged to the spherical hinge at the upper end of the landing leg to form a revolute pair of the main shock absorber relative to the mechanical leg assembly. The memory alloy planet detection lander has the beneficial effects that through the memory alloy landing supporting leg of the negative poisson ratio structure and the revolute pair of the main shock absorber relative to the mechanical leg assembly, the planet detection lander has high landing buffer performance, attitude control capacity and shape restorability, and after the buffer performance and attitude control capacity are enhanced, the lander can carry heavy loads.

    本发明涉及一种基于负泊松比结构的记忆合金行星探测着陆器,包括着陆器主体和缓冲结构。着陆器主体用于容纳有效载荷,缓冲结构周向等间隔地连接在着陆器主体的侧壁。缓冲结构包括:机械腿组件,主减震器以及足垫;机械腿组件包括着陆支腿,着陆支腿为负泊松比结构的记忆合金。主减震器的一端与着陆器主体连接,另一端与着陆支腿上端的球形铰链相铰接,形成主减震器相对机械腿组件的转动副。本发明的有益效果是:通过负泊松比结构的记忆合金着陆支撑腿和主减震器相对机械腿组件的转动副,使得行星探测着陆器具备较强的着陆缓冲性能、姿态控制能力以及形状可恢复性,且在缓冲性能和姿态调控能力增强后,着陆器还可以携带较重的载荷。
