[0021] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the utility model provides a kind of technical scheme: a hidden access control unlocking device, including machine body 1, cover plate 2 and control button 3, the inside of machine body 1 is provided with cover plate 2 extending to outside, the inside of cover plate 2 is installed with control button 3, the inside of cover plate 2 is welded with limit gear ring 4, the inside of machine body 1 is installed with servo motor 5 by bolt, the output end of servo motor 5 is connected with first support rod 501 by shaft coupling, the end of first support rod 501 away from servo motor 5 is connected with second support rod 502 by pivot, the end of second support rod 502 away from first support rod 501 is connected with third support rod 503 by pivot, the inner wall of machine body 1 is installed with guide frame 504 by bolt, which is sleeved on the outside of third support rod 503.

[0022] Please refer to Figure 2 It can be known that the end of third support rod 503 away from second support rod 502 is connected with fixed rod 505 by pivot, and fixed rod 505 is welded with one side of cover plate 2, the outer wall of third support rod 503 and the inner wall of guide frame 504 are slidably connected.

[0023] In practical implementation, when maintenance is required on the interior of the concealed access control unlocking device, the servo motor 5 is activated in forward rotation mode. The output end of the servo motor 5 drives the first support rod 501 to rotate via a coupling. The end of the first support rod 501 away from the servo motor 5 pushes the second support rod 502 to move. The movement of the second support rod 502 pushes the third support rod 503 to move. The third support rod 503 slides on the inner wall of the guide frame 504. The third support rod 503 pushes the fixed rod 505 to move. The movement of the fixed rod 505 pushes the cover plate 2 to separate from the body 1, and the fixed rod 505 flips the cover plate 2 upward, opening the interior of the body 1. This makes the interior of the concealed access control unlocking device easier to inspect and maintain, thereby reducing replacement costs due to equipment damage, extending the service life of the access control unlocking device, and ensuring the normal operation of the access control system.
