Abstract

The invention discloses a landing buffer leg structure which comprises a thigh part, a shank part and a buffer mechanism, wherein the thigh part is rotationally connected with the shank part, the first end of the buffer mechanism is rotationally connected with the thigh part, and the second end of the buffer mechanism is rotationally connected with the shank part. By arranging the buffer mechanism, the buffer landing and moving functions are integrated, and the technical problems of repeated landing and moving can be solved; the landing buffer leg structure can be switched into a buffer action mode when landing, the passive buffer capacity is provided for the legs under the action of the buffer mechanism, so that the peak value of impact loads borne by the driving mechanisms on the legs is weakened; and the landing buffer leg structure is switched to a sleep mode when walking, the buffer mechanism does not work and enters the sleep mode, and the dynamic response capability of the legs can be improved.

Description

technical field [0001] The application belongs to the field of space detection technology, and in particular relates to a landing buffer leg structure. Background technique [0002] Aluminum honeycomb buffers or hydraulic buffers are often used in the legs of legged landers used in current space exploration to absorb the impact energy during landing. When the aluminum honeycomb legs land, the irreversible deformation of the aluminum honeycomb is used to absorb energy. The hydraulic buffer legs use the internal damping holes to generate damping force buffering. Due to the sealing and temperature control problems of the hydraulic system, the existing legged landers mostly use the aluminum honeycomb leg structure. . At present, the aluminum honeycomb leg structure has the following limitations: on the one hand, the irreversible compression of the aluminum honeycomb leg structure after landing makes the legs unable to repeatedly land; on the other hand, the position of the legs...
