[0028] Wheel carriers are arranged at both sides below the vehicle body, which are respectively a left wheel carrier 41 and a right wheel carrier 42.
[0029] Among them, the left wheel carrier 41 is respectively provided with a first left guide shaft 411 and a second left guide shaft 412 at both ends, the first left guide shaft 411 passes through the vehicle body 11 upwards (the first left guide shaft is movable up and down), and is connected with the front groove 23 (the front groove on the left side) through a first left rocker 411a, the second left guide shaft 412 passes through the vehicle body 11 upwards (the second left guide shaft is movable up and down), and is connected with the rear groove 33 (the rear groove on the left side) through a second left rocker 412a.
[0030] The right wheel bracket 42 is provided with a first right guide shaft 421 and a second right guide shaft 422 at both ends, respectively. The first right guide shaft 421 passes through the vehicle body 11 upwardly (the first right guide shaft can move up and down) and is connected to the front groove 23 (the front groove on the right side) through a first right rocker 421a. The second right guide shaft 422 passes through the vehicle body 11 upwardly (the second right guide shaft can move up and down) and is connected to the rear groove 33 (the rear groove on the right side) through a second right rocker 422a.
[0031] A horizontal sensor and a controller are arranged on the vehicle body. The front motor, the rear motor, and the horizontal sensor are connected to the controller.
[0032] When working on a horizontal ground, the vehicle body remains in a horizontal state, and the front motor and the rear motor are not working (in an initial state).
[0033] When the vehicle body is tilted, the horizontal sensor transmits a signal to the controller, and the controller controls the front motor and the rear motor to work, so that the front follower and the rear follower rotate to the tilted side to adjust the state of the vehicle body until it is horizontal.
[0034] For example, when the vehicle body tilts to the left side, the controller controls the front motor to rotate so that the front follower rotates to the left side, and controls the rear motor to rotate so that the rear follower rotates to the left side. The first left rocker and the first left guide shaft move downward (the first right rocker and the first right guide shaft move upward), the second left rocker and the second left guide shaft move downward (the second right rocker and the second right guide shaft move upward), and the vehicle body gradually becomes horizontal. When the vehicle body tilts to the right side, the adjustment method is the same.
