specific Embodiment approach 1

[0007] Specific embodiment 1: This embodiment is described in conjunction with Fig. 1 to Fig. 3. This embodiment is composed of a front sprocket 1, a crawler 2, a connecting rod 3, a rotating shaft 4, a fixed shaft 5 and a rear sprocket 7, and the crawler 2 is arranged on the front On the sprocket 1 and the rear sprocket 7, the two ends of the connecting rod 3 are respectively fixed in the central holes of the front sprocket 1 and the rear sprocket 7, the connecting rod 3 is provided with a through hole 31, and the rotating shaft 4 is arranged on the connecting rod 3 In the through hole 31 on the top and installed on the connecting rod 3, one end of the fixed shaft 5 is fixed on the rotating shaft 4. During use, referring to Fig. 4 and Fig. 5, the fixed shaft 5 is fixed on the lunar vehicle body 8, and when advancing, after the engine on the lunar vehicle starts, the front wheel 9 and the rear wheel 10 of the lunar vehicle rotate and drive the vehicle body 8, and the vehicle B...

specific Embodiment approach 2

[0008] Specific embodiment two: this embodiment is described in conjunction with Fig. 1, the difference between this embodiment and specific embodiment one is: this embodiment also adds a coil spring 6, and one end of the coil spring 6 is fixed on the middle and upper part of the connecting rod 3, The other end of the coil spring 6 is fixed on the fixed shaft 5 and is close to the end on one side of the rotating shaft 4 . When the obstacle-climbing mechanism contacts an obstacle, the coil spring 6 can play the role of buffering and vibration reduction. When an obstacle acts between the fixed shaft 5 and the front sprocket 1, the rotating shaft 4 rotates counterclockwise, and the force arm of the coil spring 6 on the rotating shaft 4 becomes smaller and smaller, and it is easier to rotate, that is, it is easy to overcome the obstacle; When an obstacle acts between the fixed shaft 5 and the rear sprocket 7, the rotating shaft 4 rotates clockwise, and the force arm of the coil sp...

Abstract

The invention relates to an over-obstacle mechanism of a moonbuggy, and aims at solving the problem of limited over-obstacle height in the existing moonbuggy. The over-obstacle mechanism comprises a front chain wheel (1), caterpillar bands (2), a connecting rod (3), a rotating shaft (4), a fixing shaft (5) and a rear chain wheel (7), wherein, the caterpillar bands (2) are arranged on the front chain wheel (1) and the rear chain wheel (7), both ends of the connecting rod (3) are respectively fixed in the central holes of the front chain wheel (1) and the rear chain wheel (7), the connecting rod (3) has a through hole (31), the rotating shaft (4) is arranged in the through hole (31) of the connecting rod (3) and mounted on the connecting rod (3), and one end of the fixing shaft (5) is fixed on the rotating shaft (4). The over-obstacle mechanism utilizes the fixing shaft to drive the connecting rod then to force the front chain wheel and the rear chain wheel to move forward, so that the over-obstacle mechanism can cross the subject higher than the radius and even the diameter of the wheel of the moonbuggy.

Description

technical field [0001] The invention relates to an obstacle-surmounting mechanism. Background technique [0002] The topography of the lunar surface is relatively complex. From an overall point of view, there are lunar craters, highlands, lunar seas, cliffs, and ravines; from a local point of view, there are soft lunar soil, slopes, small pits, and lumps (such as moon rocks), etc. . The mountains, cliffs, and steep slopes inside the impact craters on the lunar surface are generally greater than 30°; the outer slopes of the impact craters are relatively gentle, generally less than 25°; the high and low areas on the lunar surface have undulating terrain, and the average slope is less than 30°; The terrain is flat and the maximum slope can reach 17°. There are a large number of rock fragments exposed on the surface of the moon, and the diameter of these rock fragments is generally less than 25cm. The traditional lunar rover relies on wheels to overcome obstacles, and the obs...
