As shown in fig. 1-2, a concave groove 2 is formed on the upper end surface of the base 1, and wheels 23 are correspondingly mounted at four corners of the concave groove. The base 1 is used for supporting and installing a display frame 3 on the upper part of the base and installing a detection device 6, and a stepping motor 7, a limiting device 9 and a controller 11 are installed in the concave groove 2.

Wherein, a wheel 23 is installed at each angular position of the base 1, and the two wheels 23 at the rear part of the base 1 are connected through the same transmission shaft, and the wheels 23 at the front part of the base 1 are independently connected.

Specifically, the wheels 23 on the left side of the front portion of the base 1 are connected with the base 1 through a transmission shaft, and the wheels 23 on the right side of the front portion of the base 1 are connected with the base 1 through another transmission shaft.

As shown in FIGS. 1-3, the display frame 3 is fixedly disposed on the upper end surface of the base 1 for increasing the aesthetic feeling of the information display device of the intelligent park enterprise and displaying the contents to be displayed.
