Embodiment Construction

[0012] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0013] exist figure 1 Among them, the slider 1 can slide on the slideway of the center bracket 2, and drives the connecting rod mechanism of the telescopic folding leg 3 to make it fold or unfold. The suspension spring 4 can make the lunar landing vehicle adapt to rough road conditions. Three stepping motors 5. Control the attitude adjustment of the wheels 6, so that the wheels 6 can have a higher degree of spatial freedom during travel, so that the lunar lander can turn freely.

[0014] exist Figure 5 Among them, the central support 2 supports and arranges various functional components; when jumping, the servo motor 7 starts to pull the steel wire rope 8, so that it drives the slider 1 to slide toward the end on the central support 2 and stretches the jumping spring 10 at the same time, and the slider 1 can pass ...

Abstract

The invention discloses a lunar surface walking device for a lunar rover, and belongs to the technical field of aerospace and mechanical designs. The lunar surface walking device is characterized by being supported by a central bracket and controlled to perform jumping and wheel-type movement. During jumping work, a servo motor pulls a steel wire rope to drive a sliding block to slide towards the end of the central bracket; a jumping spring is stretched to fold telescopic folding legs; when reaching the end of the central bracket, the sliding block is hooked by a locking hook; when the servo motor is powered off, and the locking hook releases the sliding block, the jumping spring is quickly shortened, and the telescopic folding legs are unfolded quickly; and therefore, a reacting force of the ground to wheels makes the lunar rover jump. During wheel-type movement, the telescopic folding legs are unfolded; the wheels are turned to be moving postures under the adjustment of stepping motors; motors arranged in the wheels drive the lunar rover; and therefore, the lunar rover can adapt to a rugged road surface through suspension springs arranged on the legs. The lunar surface walking device for the lunar rover has the beneficial effects that: due to the two modes of jumping and wheel-type movement, the variety of moving modes of the lunar rover is increased; and the adaptability of the lunar rover to the ground is improved.

Description

technical field [0001] The invention belongs to the technical field of aerospace and mechanical design, and relates to a new type of walking part of a lunar landing vehicle, in particular to a lunar surface walking device of the lunar landing vehicle with the functions of folding, bouncing and normal walking. Background technique [0002] At present, all countries in the world are researching and developing extraterrestrial detection equipment. The walking device of the probe has always been designed as an important part of the probe, including the six-wheel suspension of the Opportunity Mars rover developed by NASA, and the spider-type probe designed by Italy. Multi-legged, there are others such as crawler and jumping and so on. However, the current detectors all use a single lunar surface operation mode, which has insufficient ground adaptability and is not enough to adapt to the changeable lunar surface environment. Contents of the invention [0003] The purpose of the...
