[0021] The card scanning assembly 4 is disposed on the rear side of the rear cover 2 . The card scanning assembly 4 located on the rear side of the rear cover 2 can identify the access control card 7 in the rear cover 2 .

[0022] The intercom component 6 , the password component 5 , and the card scanning component 4 are distributed from top to bottom at the front end of the front cover 1 , and the card swiping component 3 is located on the top surface of the front cover 1 .

[0023] The rear cover 2 is embedded in the front cover 1 from the back to the front and is interference-connected with the front cover 1. When the front cover 1 and the rear cover 2 are closed, a closed box structure is formed.

[0024] There are multiple access control cards 7, which are distributed in a linear array along the front-to-back direction. The access control cards 7 are plate-like structures. The access control cards 7 are placed vertically, and the front ends of the top and bottom surfaces of the rear cover 2 are both tilted downward.

[0025] The pop-up assembly includes a pop-up spring 10 and a relay 11. The relay 11 is fixed to the side wall inside the back cover 2. The pop-up spring 10 is an arc-shaped spring sheet. The relay 11 is located on the inner arc side of the pop-up spring 10. The access card 7 is located on the outer arc side of the pop-up spring 10.

[0026] The upper part of the rear cover 2 is an electric control cavity 12, in which a control circuit is embedded. The card swiping component 3, the card scanning component 4, the password component 5, and the intercom component 6 are all electrically connected to the control circuit. The lower part of the rear cover 2 is a power connection cavity 13, in which a lithium battery is embedded. The card swiping component 3, the card scanning component 4, the password component 5, the intercom component 6, and the control circuit are powered by the lithium battery.
