The switch blocking piece 131 is located on the bottom surface 134 of the door cover 130, and the switch blocking piece 131 corresponds to the position of the recess 1721 of the off switch in the sliding direction of the door cover 130. The switch flap 131 can trigger the photoelectric switch 172 to make the photoelectric switch 172 output a third level signal or a fourth level signal, wherein the third level signal and the fourth level signal are opposite level signals. Specifically, when the door cover 130 is closed, the switch blocking piece 131 extends into the groove 1721 of the photoelectric switch 172, so that the switch blocking piece 131 triggers the photoelectric switch 172, and the photoelectric switch 172 outputs a third level signal corresponding to the closed state of the door cover 130, for example, outputs a high level signal or a low level signal, so that a test instrument or a third party device can determine that the door cover 130 is in the closed state. When the door 130 is opened, the switch flap 131 moves out of the recess 1721 of the photoelectric switch 172, and the switch flap 131 triggers the photoelectric switch 172. The photoelectric switch 172 outputs a fourth level signal corresponding to the opened state of the door cover 130, for example, outputs a low level signal or a high level signal. So that the test instrument or the third party equipment determines that the door 130 is in the open state.

Specifically, the top surface 133 and the bottom surface 134 of the door cover 130 are both provided with crash pads 180, and the crash pads 180 are made of an elastic material, for example, the crash pads 180 are made of sponge or rubber, so as to prevent the door cover 130 from being damaged by hitting the upper and lower edges of the housing 110 during frequent opening and closing processes, and reduce the impact noise generated by opening and closing the door cover 130.
