The back plate 112 and the cover plate 111 are parallel at this time, and there is a space between the back plate 112 and the cover plate 111. The open state refers to that when the terminal device 200 is in a use state, the back plate 112 and the cover plate 111 form a preset included angle, so that the included angle between the display surface of the terminal device 200 and the cover plate 111 forms a preset angle (for example, 120 degrees, 130 degrees, or 135 degrees, etc.).

Backplane 112 is for connecting terminal device 200, and when terminal device 200 is connected to backplane 112, backplane 112 is located on the back of terminal device 200.
