s3, in the running process of the transport vehicle, the running direction of the transport vehicle needs to be controlled by rotating a steering wheel (407), the tail end of the output end of an angle sensor (305) is attached to the bottom of a steering arm (301) through a connecting column, when the steering arm (301) rotates, the output end of the angle sensor (305) rotates along with the rotation, the steering characteristic of the steering arm (301) can be converted into a quantity unit, when the steering arm (301) and a rotating rod (304) are in a vertical state, the initial value of the angle sensor (305) is zero, when a user sits in a space I and rotates the steering wheel (407) to the left side, the rotating rod (401) is driven to rotate, then a spur gear (4) is driven to perform circular motion, a tooth groove on the outer surface of the spur gear is mutually embedded with a tooth groove of a rack (303), and when the transport vehicle rotates, the rack (303) is driven to be pushed to the rotating direction of the transport vehicle, the two are mutually matched, so that the circular motion applied along with the straight gear (4) is conveniently converted into the linear motion of the rack (303), then the driving force generated by the forward and backward motion of the rack (303) can be transmitted to the wheel carrier (1) through the steering pull rod (302) and the steering arm (301), and the wheel carrier (1) is enabled to deflect towards the same direction;

s4, the electric push rod (6) can change the length of the electric push rod under the control of electric power, the electric push rod is electrically connected with the distance sensor (504), when the distance sensor (504) senses that the distance between the obstacle and the electric push rod is within a set range, the electric push rod (6) can be started and outwards extend the length of the electric push rod to push a part on one side of the electric push rod outwards, the anti-collision plate (603) is of a rigid structure and has certain hardness, when the vehicle head (5) is impacted, the pushing force generated by the impact can be transmitted to the spring group (602) through the anti-collision plate (603), the spring group (602) is installed between the electric push rod (6) and the anti-collision plate (603), the spring group (602) has high elastic deformation capacity, and when the vehicle head (5) is impacted, the force generated by the impact can be absorbed by the spring group (602), so that the vehicle head (5) is prevented from directly impacting the obstacle and absorbing the impact force, the damage to the vehicle body can be reduced.
