The rollover-resistant reinforced smart car according to claim 6, characterized in that: Each group of the sliding components comprises two second connecting rods (502), a sliding block (503) and two movable connecting rods (504); one end of each of the second connecting rods (502) is hinged to the top of the outer wall of the movable block (406), and the other end of each of the second connecting rods (502) is hinged to one side of the outer wall of the sliding block (503); the sliding block (503) and the mounting frame (401) are slidably matched; the top end of each of the movable connecting rods (504) is hinged to one side of the outer wall of the sliding block (503), and the bottom end of each of the movable connecting rods (504) is hinged to one side of the outer wall of the support rod (501).

8. The rollover-resistant reinforced smart car according to claim 7, characterized in that: Each group of the supporting components comprises a placement frame (505) and a rotating shaft (506); the placement frame (505) is fixedly arranged on the top of the outer wall of the installation frame (401); the rotating shaft (506) is fixedly arranged on one side of the outer wall of the placement frame (505); and the top end of each support rod (501) is movably sleeved on the outer wall of the rotating shaft (506).

9. A control method for a rollover-resistant reinforced intelligent vehicle, characterized in that: The method is applied to the anti-rollover reinforced smart car according to claim 8, comprising the following steps: S1: Switching the track wheels: When the smart car needs to travel on a rough or soft ground, the hydraulic cylinder (202) is activated to move the moving rod (203) at the bottom of the smart car body (1), drive the scissor-type connecting rod (204) to unfold, and make the bottom end of the scissor-type connecting rod (204) drive the moving block (206) to slide in the mounting frame (205), so as to drive the track base (201) to move downward, lift the smart car body (1) as a whole, make the normal wheels on the smart car body (1) leave the ground, and rely on the track wheels on the track base (201) to drive the smart car body (1) to move, thereby improving the grip and stability of the smart car on the rough or soft ground, and reducing and preventing the occurrence of rollover; S2: Adjusting the center of gravity position: The monitoring device (3) detects the posture and acceleration changes of the smart car in real time to predict the risk of rollover. When it is detected that rollover is about to occur, one of the forward and reverse motors (404) can be started to drive the first bidirectional threaded rod (405) to rotate in the installation frame (401), so that the two movable blocks (406) drive the first connecting rod (407) to move. The first connecting rod (407) pulls the movable frame (402) on the connecting member (408) to slide in the installation frame (401), thereby changing the position of the iron block (403) and adjusting the center of gravity of the smart car to prevent the smart car from rolling over. S3: Supporting the smart car: When it is detected that rollover is about to occur, the two movable blocks (406) move, which also drives the second connecting rod (502) to move, so that the second connecting rod (502) pulls the sliding block (503) to slide on the mounting frame (401), and the sliding block (503) drives the moving connecting rod (504) to move. One end of the moving connecting rod (504) lifts the supporting rod (501), so that when the smart car rolls over, the side of the smart car is supported, which can quickly stabilize the posture of the smart car, prevent the smart car from further rolling or sliding, and reduce the impact of the rollover on the structure and internal parts of the smart car; S4: Installing and fixing the iron block (403): placing the iron block (403) in each movable frame (402) as required, and manually rotating the second bidirectional threaded rod (410) to rotate it between the two fixing frames (409), thereby driving the two fixing plates (411) to approach each other, and installing and fixing the iron block (403), so that the iron blocks (403) of different weights can be replaced as required to meet the needs of adjusting the center of gravity of the intelligent car.
