[0031] The damping block 315 is located on the displacement track of the sliding block 312, the damping block 315 is provided with a plurality of damping blocks 315, and is linearly arrayed on the side of the vertical plate 314, the side of the sliding block 312 close to the damping block 315 is provided as a circular arc surface, and the plurality of damping blocks 315 are beneficial to increase the resistance when the extension rod 38 rebounds.

[0032] The telescopic rods 38 and the springs 39 are provided in pairs and symmetrically along the vertical central axis of the trolley body 1, the bottom of the trolley body 1 is provided with infrared sensing stop probes 36, and the infrared sensing stop probes 36 are provided, which is beneficial to sensing in time when the trolley is blocked, remote control, and preventing damage.

[0033] The infrared sensing stop probes 36 are provided in pairs and symmetrically along the vertical central axis of the trolley body 1, the wheels 31 are provided in pairs, and the vertical central axes of the computer mainboards 34 are symmetrically arranged, and the trolley is controlled and operated by the computer mainboard 34.

[0035] In this embodiment, the system inside the computer motherboard 34 is used for intelligent control, and a remote control is designed for remote control. The double lines 35 control the front and rear motors 33, and the four-wheel drive motor 33. The motor 33 is independently operated. The output shaft of the motor 33 can drive the gear transmission assembly inside the rotating disc 5 to rotate. The gear transmission assembly drives the round rod 32 to rotate. The round rod 32 drives the wheels 31 to rotate. By adjusting the bolts 37, the connection between the wheels 31 and the round rod 32 can be loosened, and the wheel track of the wheels 31 can be adjusted at will. After adjustment, the adjustment bolts 37 are tightened again, so that the wheels 31 and the round rod 32 are in a state of tight connection. The front and rear are equipped with this infrared sensing stop probe 36, which automatically stops. The function of the remote control can control the forward and backward movement of the transport vehicle body 1, and has the function of walking when pressed and stopping when released. In order to prevent the transport vehicle body 1 from being damaged by vibration during movement, a shock absorbing assembly 3 is designed. When the transport vehicle body 1 moves and is subjected to vibration, the spring 1 39 and the telescopic rod 38 will be squeezed, the telescopic end of the telescopic rod 38 will be squeezed up and down, the spring 1 39 will be squeezed, the vibration of the wheels 31 will be reduced, and the telescopic rod 38 will move downward, driving the cross rod 310, the rectangular frame 311, the sliding block 312 and the spring 2 313 to move downward. When the sliding block 312 moves downward, it will contact the damping block 315. The damping block 315 is made of rubber material. When the sliding block 312 moves downward, the arc surface of the sliding block 312 will contact the damping block 315 first. The design of the arc surface makes the resistance small at this time. When the sliding block 312 moves downward, the speed of the sliding block 312 following the telescopic rod 38 will be too fast. However, when the telescopic rod 38 is not subjected to compression and rebound, it will drive the cross rod 310, the rectangular frame 311, the sliding block 312 and the spring 2 313 to move upward. When the sliding block 312 moves upward, the side of the non-arc surface will contact the damping block 315 first. Then, the resistance between the sliding block 312 and the damping block 315 will be increased, the friction will be increased, the speed of the sliding block 312 following the telescopic rod 38 will be slowed down when rebounding upward, the rebound speed of the telescopic rod 38 will be slowed down when not subjected to vibration, and the vibration of the transport vehicle during rebound will be reduced. Through the design of the telescopic rod 38, the sliding block 312 and the damping block 315, the movement speed and resistance can be effectively adjusted when the vehicle body is vibrating. When the telescopic rod 38 rebounds, the increase of resistance can reduce the rebound speed, so as to avoid the possible additional impact or vibration on the vehicle body caused by too fast rebound, which helps to maintain the stability of the vehicle body. For the transport vehicle during turning, it is very important to slow down the rebound speed, because too fast rebound may cause the vehicle body to lose control or turn unstably.
