[0007] The display screen module comprises an LCD display screen, a screen interface board and a screen body structure assembly.

[0008] The controller module comprises a network communication module, a main controller, a power supply, a backlight plate, a main control interface board and a main control cover plate.

[0009] A protective cover is further arranged on the display screen module, and the protective cover covers the surface of the female connector.

[0010] A slot buckle is further arranged on the protective cover, and a buckle slot is arranged on the shell of the display screen module corresponding to the position of the slot buckle.

[0011] In summary, the application includes at least one of the following beneficial technical effects: the dynamic map rear cover modular structure completely separates the screen module and the control system, and is designed as two independent modules, an LCD display module and a controller module, which can be replaced individually. The display screen module and the controller module are quickly replaced by using a sliding slot opening mode. The module circuit is connected by using a plug connector, which realizes quick disassembly and is easy to maintain and install. BRIEF DESCRIPTION OF DRAWINGS
