Travelling and folding system of moon rover

Abstract

The invention relates to a travelling and folding system of a moon rover, comprising a wheel driving unit, wheel steering units, a steering frame, a front rocker arm, a rover body, a rover body transmission shaft, a rear rocker arm, a middle rod and a swing rod; wherein the wheel driving unit is connected with wheel steering unit; two wheel steering units are fixed with the steering frame and the other steering unit is fixed with the swing rod; the steering frame is connected with the front rocker arm by a rotating shaft; the swing rod is connected with the middle rod by a rotating shaft; the middle rod is fixed with the rear rocker arm; the front rocker arm and the rear rocker arm are respectively connected with the rover body transmission shaft; the transmission shaft is connected with the rover body. The folding mode is simple, convenient and fast; the folding state is beautiful in appearance; the using amount of the motors is less, a steering motor is fully utilized, only two swing motors are really designed for the folding function and the other six steering motors also can be used for normal travelling and turning; the folding ratio is high, namely 214 percent, thus effectively shortening the initial placement volume of the moon rover.

Description

technical field [0001] The invention relates to a device in the field of mechanical technology, in particular to a lunar rover walking and folding system. Background technique [0002] The focus of the exploration of space beyond the earth is various planetary / satellite celestial bodies, and an important way to detect these celestial bodies is to send a mobile rover that can land to conduct close-range exploration on the surface. In order to save the cost of rocket launch and aircraft operation, it is required that the initial placement volume of the rover must be as small as possible. Therefore, the rover should have a foldable function. When it is installed in the spacecraft, it should be in a folded state. After reaching the surface of the planet / satellite, it will be fully unfolded and resume normal walking and working state. [0003] Carried out literature search to prior art, the result is as follows. Many scientific research institutions at home and abroad have rese...

Problems solved by technology

However, they did not fully consider the folding function from the beginning of the design, or did not fully design the folding function according to the characteristics of the walking system and body mechanism, so the folding ratio of these models is not high
