5G demonstration display device in 5G test vehicle

The utility model belongs to the technical field of information display, and particularly relates to a 5G demonstration display device in a 5G test vehicle, which comprises a display body, a rotating column is rotatably connected in the display body, a support base is arranged below the display body, one side of the support base is fixedly connected with a linkage plate, and the linkage plate is fixedly connected with the display body. Clamping blocks are rotationally connected to the two sides of the linkage plate, and a dispersion plate is arranged above the supporting base; the gravity center is lowered by rotating the display body, so that the phenomenon that the display body topples over due to the too high center in the bumping process is prevented, the receiving surface, subjected to bumping acting force, of the display body is enlarged through cooperation of a dispersion plate and a spring, and the acting force is smaller; parts in the display body are protected from being extruded and damaged in a ma
