The first support rod 51 is fixedly connected to the display screen module 1, and the second support rod 52 is connected to the battery pack module 2. The first support rod 51 and the second support rod 52 are hinged. When retracted, the first support rod 51 and the second support rod 52 are in a folded state, and when unfolded, the first support rod 51 and the second support rod 52 are in a flat state. The opening and closing support rod 5 adopts the structure of a hydraulic support rod, and the hydraulic structure is used to control the switching of the folding and flattening processes of the first support rod 51 and the second support rod 52. When the opening and closing support rod 5 is folded, the battery pack module 2 and the display screen module 1 can fit each other for easy transportation. When the opening and closing support rod 5 is flat, the battery pack module 2 and the display screen module 1 are relatively open, and the length of the opening and closing support rod 5 limits the opening angle of the battery pack module 2 and the display screen module 1. Under the condition of supporting the advertising machine, the display screen module 1 will not be too tilted to affect the display.

[0031] When the outdoor LED display advertising machine is displaying advertisements, the battery pack module 2 and the display screen module 1 are propped open along the hinge 4 until the opening and closing support rod 5 is laid flat to form a "human" shape structure, and the entire advertising machine can stand upright. The power switch 32 is turned on, and the energy storage battery 22 supplies power to the LED screen 12, and the required advertising content is displayed on the LED screen 12. The user can connect to the main board 31 through the wireless module 35 through the APP to switch the advertising content; when transporting, the battery pack module 2 and the display screen module 1 are folded and attached along the hinge 4. At this time, the opening and closing support rod 5 is in a folded state, and the entire advertising machine is tilted so that only the moving wheels 6 touch the ground. The user holds the handle 8 to push the entire advertising machine to move.

[0032] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
