Abstract

The invention provides a combined 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 sixth rod, a seventh rod and a third rod form a closed rectangle; one end of a fourth rod is hinged with the middle of the sixth rod and the other end thereof is hinged with the middle of the third rod; the second rod and the fourth rod are arranged in parallel; one end of the seventh rod is hinged with one end of a ninth rod by a second rotary locking device; the other end of the ninth rod is hinged with a second wheel; the side wall of the fourth rod is fixedly connected with one end of a guide rail; the guide rail and a slider are locked by a locking pin; the side wall of the slider is fixedly connected with the side wall of a tenth rod; and the tenth rod, an eleventh rod, a twelfth rod, a thirteenth rod and an extension spring form a 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 vehicle cannot simultaneously have a good folding function and superior mobility, the present invention provides a combined foldable suspension type six-wheel vehicle-mount...
