The AGV provided with the supporting leg mechanism has two use states, namely an unfolding state of the supporting leg mechanism and a folding state of the supporting leg mechanism.

FIG. 1 shows an AGV with a leg mechanism deployed.

FIG. 2 shows the folded configuration of an AGV with a leg mechanism.

As shown in fig. 1-7, the AGV includes a body 1 and a leg mechanism, the leg mechanism includes 4 legs including a first leg 3, a second leg 11, a fifth leg 14 and a fourth leg 13, and one end of each of the four legs is hinged to the body 1 and can rotate within a predetermined angle range around the hinge. The first leg 3 and the second leg 11 are provided on one side of the vehicle body, and the fourth leg 13 and the fifth leg 14 are provided on the other side of the vehicle body. The supporting legs on the two sides are symmetrically arranged.

Every landing leg all includes swing arm 8, hydraulic cylinder 9, the one end and the articulated connection of automobile body 1 of swing arm 8, the other end vertically is provided with hydraulic cylinder 9, hydraulic cylinder 9's piston rod sets up down, and its lower extreme is provided with the stabilizer blade, the piston rod tip is universal bulb, the stabilizer blade is connected with the tip is articulated.
