Abstract

The invention provides a multi-spring constrained quadrilateral foldable and extendable suspension type six-wheel vehicle-mounted mechanism, relating to a foldable and extendable six-wheel vehicle-mounted mechanism. By adopting the mechanism, the problem that a probe vehicle can not simultaneously have a good folding function and superior mobility performance at present is solved. The mechanism is characterized in that a second rod, a third rod, a fourth rod, a seventh rod and a first extension spring form a first spring constrained quadrilateral mechanism; a fifth rod, a sixth rod, an eighth rod, a seventh rod and a second extension spring form a second spring constrained quadrilateral mechanism; the side wall of the seventh rod is fixedly connected with one end of a guide rail; the guide rail and a slider are locked by a locking pin; and a tenth rod, an eleventh rod, a twelfth rod, a thirteenth rod and a third extension spring form a third spring constrained quadrilateral mechanism. The mechanism is used for planetary exploration.

Description

technical field [0001] The invention relates to a foldable six-wheel vehicle-mounted mechanism. Background technique [0002] At present, researches on planetary exploration vehicles at home and abroad are mainly focused on the mobile performance of its mobile mechanism, and rarely consider the folding function of the vehicle body. Under the constraints of rocket space and launch costs at the current stage, the folding function is of great significance for the rover, which can solve the contradiction between functional diversity and volume. With the implementation of my country's lunar exploration project, the vehicle-mounted mechanism with folding function and superior mobility is receiving more and more attention. Contents of the invention [0003] In order to solve the problem that the current probe car cannot have excellent mobility while having a good folding function, the present invention provides a multi-spring-constrained quadrilateral foldable suspension type si...
