The technical scheme adopted for solving the technical problems is as follows: the utility model provides a prevent mechanical structure of moon rover every single move, including rotating the unit, rotating the unit and including the set square, connecting rod one, connecting rod two and connecting rod three, the summit in the set square and the fixed axle normal running fit on the automobile body back lateral wall of moon rover, and the face and the automobile body back lateral wall parallel arrangement of set square, the one end of connecting rod one links to each other with the summit two in the set square is fixed, the other end of connecting rod one and the one end of connecting rod two pass through ball connection and realize normal running fit, the one end of connecting rod three links to each other with the mount that is used for fixed moon rover rear wheel is fixed, the other end of connecting rod three and the other end of connecting rod two pass through ball connection and realize normal running fit, it has connecting rod four to articulate between the summit three in the set square in two and two rotating the unit.
The triangle is an isosceles triangle, the first vertex and the third vertex are two base angles of the isosceles triangle, and the second vertex is the vertex angle of the isosceles triangle.
The connecting rod IV comprises a straight rod and U-shaped blocks connected with two ends of the straight rod, through holes are formed in two side walls of the U-shaped blocks oppositely, the straight rod is vertically connected with the bottom wall of the U-shaped block, and the vertex III of the triangular plate is arranged between the two side walls of the U-shaped block and forms running fit through bolts.
The beneficial effects are that: when the lunar rover climbs the slope, the fixing frame of the lunar rover rear wheel can have certain fluctuation, the lunar rover body is subjected to certain traction through the two rotating units, 360-degree rotation angles can be realized at the ball connecting positions inside the rotating units so as to adapt to different slopes, the lunar rover body and the slope are parallel in the climbing or descending process, the balance of the lunar rover is ensured, and the lunar rover has a simple whole structure and low cost.
