Abstract

An extraterrestrial adversity lander capable of automatically adjusting a foot end grounding point comprises a main structure box body and self-adaptive landing leg mechanisms arranged on the four side faces of the main structure box body, each landing leg mechanism comprises a main branch chain, two auxiliary branch chains and adjusting locking joints corresponding to the main branch chain and the two auxiliary branch chains, and in the stage of adjusting the foot end grounding point, the locking joint is adjusted to only drive the two auxiliary branch chains to move, the main branch chain is not driven, and the leg mechanism keeps the attribute of the fixed truss structure in real time in the adjusting process; in the landing buffering stage, the locking joints are adjusted to be fixed without deformation, and the main branch chains achieve buffering energy absorption through deformation. The novel landing leg mechanism based on the adjusting locking joint is innovatively designed, and the hooke joint of the buffering branch chain is always attached to the side wall of the main structure box body in the process of adjusting the foot end contact point, so that the real-time movable truss attribute in the adjusting process is guaranteed. And when the locking joint is locked when adjusted, the landing leg is changed into a fixed truss structure again.

Description

technical field [0001] The invention relates to a technology in the field of space probes, in particular to an alien adversity lander capable of autonomously adjusting the contact point of feet. Background technique [0002] Landing detection on the alien surface is an important technical means to understand the evolution of the planet and the composition of the surface. The existing leg-type landing technology makes the leg mechanism expand and lock after entering the stage, and the whole lander becomes a truss structure, so that the configuration of a single leg cannot be changed, that is, the position of the touch point of the foot relative to the fuselage is fixed. Therefore, the existing landing plan strictly restricts the site selection of the landing site to ensure safety and reliability. It is required to land in an area with a small slope and a flat surface such as an alien plain. For example, the landing sites of the lunar lander are distributed outside the lunar m...
