[0002] The smart access control face recognition device is an advanced technical device applied to the access control system. It combines face recognition technology and access control system to achieve safer and more convenient access control management. This device usually includes a camera for capturing facial images, an artificial intelligence algorithm for analyzing and identifying faces, and an access control system for controlling the opening and closing of doors.

[0003] Smart access control face recognition devices are currently usually fixed on one side of the protective door. However, due to the different heights of different people, some problems arise during use. For example, taller people need to bend over or squat to be recognized, while shorter people need to stand on tiptoe to complete the recognition, which makes the recognition process inconvenient. This situation may cause inconvenience and may even cause the recognition speed to slow down or errors when used during peak hours.

[0004] Therefore, we provide intelligent access control facial recognition devices. Utility Model Content

The sliding groove 211 provides a sliding path for the sliding block 3. When an external force indirectly drives the sliding block 3 to slide inside the sliding groove 211, it can slide along the path of the sliding groove 211.

Through the abutment of the two groups of springs 32, when the sliding block 3 is not operated by external force, the sliding block 3 can always maintain a fixed position, so that it can reset itself after the operating lever 4 is manually turned.

[0026] Furthermore, a slide rail 214 is welded to one side of the sliding seat 21, and a connecting block 33 is welded to one side of the sliding block 3. Pulleys 34 are installed on both sides of the connecting block 3 through short shaft rotation, and the pulleys 34 are slidably installed inside the slide rail 214. During the sliding process of the sliding block 3, the pulleys 34 slide inside the slide rail 214, making the sliding of the sliding block 3 smoother.

When the gear 6 rotates, it can drive the connecting shaft 7 to rotate inside the fixed seat 2.

[0030] Working principle: During access control recognition, the pitch angle of the face recognition machine 8 can be adjusted according to different heights. In the first step, when the height is short, the joystick 4 can be manually pressed, and the joystick 4 indirectly drives the sliding block 3 to slide in the sliding groove 211. The sliding block 3 drives the moving rack 5 to move downward through the connecting block 33. During the downward movement of the moving rack 5, the gear 6 meshing with it will be driven to rotate counterclockwise, and the gear 6 drives the connecting shaft 7 to rotate synchronously, thereby driving the face recognition machine 8 to tilt downward. In the third step, when the height is high, the joystick 4 can be manually lifted to operate. The rod 4 indirectly drives the sliding block 3 to slide in the sliding groove 211, and the sliding block 3 drives the moving rack 5 to move upward through the connecting block 33. During the upward movement of the moving rack 5, it will drive the gear 6 meshing with it to rotate clockwise, and the gear 6 drives the connecting shaft 7 to rotate synchronously, thereby driving the face recognition machine 8 to rotate upward. In the fourth step, when the joystick 4 loses external force, the springs 32 located at both ends of the sliding block 3 restore their deformation, thereby resetting the sliding block 3, and the sliding block 3 indirectly drives the face recognition machine 8 to return to its position, thus completing the use process of the intelligent access control face recognition device.
