In the process of ascending or climbing steps, under the action of the plate spring 14, the middle part of the first crawler belt 10 protrudes downwards, so that the first crawler belt 10 contacts the ground to a greater extent; during a downhill descent or a step, the middle portion of the first track 10 is raised upward by the plate spring 14 to make the first track 10 contact the ground to a greater extent.

When a higher obstacle is encountered during walking, the first crawler belt 10 runs over the obstacle, at this time, the middle part of the frame 1 moves to the position of the obstacle, the driving mechanism 5 drives the second driving wheel 15 to rotate, the second driving wheel 15 drives the second crawler belt 11 to rotate, and the frame 1 stably runs over the obstacle under the action of the second crawler belt 11. Effectively prevent to make the barrier contact with frame 1 bottom surface because of the barrier is higher to damage the chassis of frame 1, do benefit to the device and adapt to various comparatively complicated topography.

The method further comprises a combination method of the all-terrain carrying vehicle, the length of the first vehicle frame 1 and the length of the second vehicle frame 3 are both preset to be L, and the method comprises the following steps:

when the length of the required carrying vehicle is 0-L, the carrying vehicle consists of 1 unit of driving units;

when the length of the required carrying vehicle is L-2L, the carrying vehicle consists of two driving units, and the total number of the driving units is 2;

when the length of the required carrying vehicle is 2L-3L, the carrying vehicle combination mode comprises 3 units of a driving unit, a supporting unit and a driving unit from left to right in sequence;

when the length of the required carrying vehicle is 3L-4L, the carrying vehicle combination mode comprises 4 units of a driving unit, a supporting unit and a driving unit from left to right in sequence;

when the length of the required carrier vehicle is 4L-5L, the carrier vehicle combination mode sequentially comprises 5 units of a driving unit, a supporting unit, a driving unit, a supporting unit and a driving unit from left to right;

when the length of the carrier vehicle is 5L-6L, the carrier vehicle combination mode comprises 6 units from left to right in turn, namely a driving unit, a supporting unit, a driving unit, a supporting unit and a driving unit or the driving unit, the supporting unit and the driving unit;

when the length of the required carrier vehicle is 6L-7L, the carrier vehicle combination mode sequentially comprises 7 units of a driving unit, a supporting unit, a driving unit, a supporting unit and a driving unit from left to right;

when the length of the carrier vehicle is 7L-8L, the carrier vehicle combination mode sequentially comprises a driving unit, a supporting unit, a driving unit, a supporting unit, a driving unit or a driving unit, a supporting unit, a driving unit, a supporting unit and a driving unit from left to right, and the total number of the units is 8;

in the method for combining the all-terrain carrier vehicle, any adjacent units are detachably connected, and in consideration of the integral support and strength of the device, at most two support units are arranged between any adjacent drive units.

While embodiments of the invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
