The landing device foot structure comprises a servo electric cylinder and a landing system foot end, the landing system foot end comprises an upper portion, a ground contact foot pad and other components, the upper portion foot pad is made of metal rubber materials with porosity distributed in a gradient mode, the structure is constructed through the selective laser melting technology, and stress redistribution is achieved through cooperation of reinforcing ribs; according to the foot pad, through multi-scale topological optimization and functional modularization integration, the foot pad is divided into two functional units for dispersing stress, prolonging the service life of parts, making contact with the ground, mixing patterns on the bottom face of the foot pad and regulating and controlling the friction coefficient, so that a lander can stably reside in a special-shaped terrain, and can actively penetrate through the surface of a complex medium in cooperation with landing legs, expand the detection space and reside on a slope surface; all the parts are cooperatively adjusted, the posture is precisely restrained, safety and stability are guaranteed, after residence, the spring insertion rod and the telescopic liquid bag are reset, reset hindrance is overcome, maneuverability is improved, lunar dust is vibrated and removed when the foot pad is separated, and performance is maintained.

    本发明公开了一种具有足底花纹的着陆器足部结构,包括伺服电缸和着陆系统足端,着陆系统足端含上部、触地足垫等部件,上部足垫用孔隙率梯度分布的金属橡胶材料,经激光选区熔融技术构建结构,配合加强筋实现应力再分配;该足垫通过多尺度拓扑优化与功能模块化集成,将足垫分为两大功能单元分散应力,延长部件寿命,触地足垫底面混合花纹,调控摩擦系数,使着陆器能在异形地形稳定驻留,配合着陆腿可在复杂介质表面主动穿越,拓展探测空间,坡面驻留时,各部件协同调节,精准约束姿态,保障安全稳定,驻留后,弹簧插杆与伸缩液囊复位,克服复位阻碍,提高机动性,且足垫分离时振除月尘,维持性能。
