Description

Technical Field

[0001] The present invention relates to the technical field of intelligent access control, and in particular to a face recognition access control with a monitoring function. Background Art

[0002] The face recognition access control system is a security management device based on artificial intelligence and biometric technology. It uses cameras to capture and identify facial features to achieve identity authentication and access control. Compared with traditional access control methods, the face recognition system does not require a physical card or password. Users can enter and exit by simply scanning their faces, which improves convenience and security. Most face recognition access control systems have a touch screen on the panel, providing an intuitive interactive interface for easy system settings, function selection, and user information management. Users can use the touch screen to perform operations other than identity authentication, such as password input, identity selection, etc.

[0003] Some face recognition access control panels are provided with some protective covers to protect the touch screen. When the user needs to operate the touch screen, the user needs to lift up the protective cover to expose the touch screen. After the access control is unlocked, the protective cover is reset again. However, the face recognition access control panel protective cover in the prior art lacks a self-resetting structure of the protective cover. The user easily forgets to reset the protective cover, thereby exposing the touch screen, increasing the risk of screen damage and aging, and reducing the security and cleanliness of the system. In addition, the protective cover lacks a cleaning component for the touch screen. When the user triggers the touch screen multiple times, dirt will accumulate on the surface of the touch screen, affecting the display effect and touch sensitivity. Summary of the invention

[0039] When the locking spring 10 is at its original length, the locking bevel block 9 is at the farthest distance from the output end of the release electric push rod 13. When the locking bevel block 9 is under pressure, the locking bevel block 9 will be close to the output end of the release electric push rod 13, and the release electric push rod 13 will be connected to the control circuit of the access control body 3. When the access control body 3 is unlocked, the release electric push rod 13 will retract.

[0040] The cleaning assembly includes an active roller 17, a driven roller 18, a cleaning cloth 16, and a flattening roller 15. A follower winding assembly is provided on the top of the active roller 17 for automatically winding the dirty cleaning cloth 16 when the protective cover 6 moves upward. The bottom surface of the locking bevel block 9 and the top surface of the driven bevel block 35 are both arranged as inclined surfaces. The bottom surface of the locking bevel block 9 and the top surface of the driven bevel block 35 are parallel to each other. When the locking bevel block 9 is pushed by the driven bevel block 35, the locking bevel block 9 will be forced to move laterally, compressing the locking spring 10.

[0041] The follower winding assembly includes a driven gear 34, a one-way bearing 31, a horizontal column 33, a vertical bevel gear 32, a horizontal bevel gear 24, and a vertical column 21. The inverted U frame 23 is vertically fixed on the top of the installation box 61. The active roller 17 is rotatably connected to the bottom center of the inverted U frame 23. A front locking frame 19 is fixedly arranged on the front side of the inner cavity of the installation box 61. The front locking frame 19 is provided with a bottom groove 20 at the bottom of the rotating shaft of the driven roller 18. A bottom plate 28 is fixedly arranged at the bottom of the rotating shaft of the driven roller 18. The top of the bottom plate 28 has a hemispherical hole 29 in a circular array. The user can insert a rod-shaped tool into the hemispherical hole 29 to control the rotation of the driven roller 18.

[0042] A rear locking frame 14 is fixedly arranged on the rear side of the inner cavity of the installation box 61, and a flattening roller 15 is symmetrically rotatably connected inside the rear locking frame 14, and the two flattening rollers 15 are in a parallel state. The front locking frame 19 is rotatably connected to a driven roller 18 on one side of the active roller 17, and the outer wall of the active roller 17 is bonded to one end of the cleaning cloth 16, and the outer wall of the driven roller 18 is bonded to the other end of the cleaning cloth 16. The two flattening rollers 15, the driven roller 18, and the active roller 17 are commonly sleeved with a cleaning cloth 16, and the cleaning cloth 16 on one side of the two flattening rollers 15 is parallel to the touch screen on the side of the access control body 3, and is in a state of being in contact with the touch screen on the side of the access control body 3.

[0043] A vertical column 21 is fixedly provided on the top of the rotating shaft of the active roller 17, a horizontal bevel gear 24 is fixedly provided on the bottom of the outer wall of the vertical column 21, a horizontal column 33 is rotatably connected to the side of the inverted U-frame 23, a vertical bevel gear 32 is fixedly provided at one end of the horizontal column 33, a one-way bearing 31 is provided on the outer wall of the other end of the horizontal column 33, a driven gear 34 is fixedly provided on the outer ring of the one-way bearing 31, and the side of the driven gear 34 is stably meshed with the side of the vertical gear rod 38, so the vertical gear rod 38 can only push the active roller 17 to rotate in one direction through the driven gear 34 and the one-way bearing 31, and a certain amount of cleaning cloth 16 is wound around it, and a locking component is provided on the top of the outer wall of the vertical column 21 to maintain the active roller 17 wrapped with a certain amount of cleaning cloth 16.

[0044] The locking assembly includes a locking ratchet 22, a locking rod 42, and a holding spring 30. The locking ratchet 22 is fixedly arranged on the outer wall of the vertical column 21. The locking rod 42 is movably inserted into the wheel groove of the locking ratchet 22 in the inner cavity of the installation box 61. The head of the locking rod 42 is arranged to be an inclined surface. The holding spring 30 is fixedly arranged on the side of the locking rod 42 in the inner cavity of the installation box 61. The side of the holding spring 30 is pressed to the side of the locking rod 42. The holding spring 30, the locking rod 42 and the locking ratchet 22 constitute a one-way non-return structure of the active roller 17, so that the active roller 17 can only actively wrap around the cleaning cloth 16 without releasing the cleaning cloth 16.

[0045] The head of the locking rod 42 is rotatably connected to the top of the inner cavity of the installation box 61, and a composite release component for releasing the locking ratchet 22 and releasing the driven roller 18 at the same time is arranged on the top of the locking rod 42 rotating shaft. The composite release component includes a release handle 39, a first connecting column 40, a second connecting column 41, an extension rod 26, and a damping column 25. One end of the second connecting column 41 is rotatably connected to the bottom of the locking rod 42 rotating shaft, and the other end of the second connecting column 41 is rotatably connected to the first connecting column 40, and the other end of the first connecting column 40 is rotatably connected to the end of the release handle 39. The release handle 39 is movably inserted into the side of the inverted U frame 23. When the release handle 39 moves laterally, the locking rod 42 is pulled to rotate by the first connecting column 40 and the second connecting column 41, and one end of the locking rod 42 moves out from the wheel groove of the locking ratchet 22. During this process, the holding spring 30 is bent, and the locking ratchet 22 can rotate freely.

[0046] An extension rod 26 is fixedly provided on the side of the release handle 39, and a damping column 25 is fixedly provided on the other end of the extension rod 26. A damping cylinder 27 is fixedly provided on the inner cavity of the mounting box 61 and the outer wall of the rotating shaft of the driven roller 18. The damping column 25 is movably inserted into the damping cylinder 27. When the damping column 25 is inserted into the damping cylinder 27, the end contacts the outer wall of the rotating shaft of the driven roller 18, applying damping to the rotation of the driven roller 18, so that the driven roller 18 releases the cleaning cloth 16.

[0047] It should be supplemented that the elastic stiffness of the vertical spring 36 is not greater than the elastic stiffness of the locking spring 10 . When the driven bevel block 35 is blocked by the locking bevel block 9 , the vertical gear rod 38 will be forced to move downward first.

[0048] The specific implementation steps and principles of the present invention are as follows: In the initial state, the protective cover 6 is on the side of the protective access control body 3. At this time, the locking spring 10 and the vertical spring 36 are both in their original length state. At this time, the locking rod 42 is inserted into the wheel groove of the locking ratchet 22, and the damping column 25 is inserted into the damping cylinder 27. The rotation of the driven roller 18 is subject to a certain damping, and the active roller 17 can only rotate in one direction, that is, it is in a state where it can only wrap around the cleaning cloth 16.

[0049] When the user lifts the protective cover 6 to the top of the side of the access control body 3, the driven bevel block 35 will be blocked by the locking bevel block 9, and the vertical gear rod 38 will drive the active roller 17 to wrap a certain amount of cleaning cloth 16 through the driven gear 34, the one-way bearing 31, the vertical bevel gear 32, and the horizontal bevel gear 24. The driven roller 18 releases a certain amount of cleaning cloth 16, and finally the bottom of the vertical gear rod 38 contacts the bottom of the inner cavity of the installation box 61. At this time, the top of the driven bevel block 35 will push the locking bevel block 9 to move horizontally, and finally the driven bevel block 35 will pass over the locking bevel block 9. The locking spring 10 will drive the locking bevel block 9 to return to the initial position, hold up the driven bevel block 35, and maintain the protective cover 6 at an appropriate height at the top of the side of the access control body 3. When the user unlocks the door through the access control body 3, releasing the electric push rod 13 will drive the locking bevel block 9 to retract, and the entire protective cover 6 will automatically fall back to the initial state due to its own weight.

[0050] When it is necessary to clean the cleaning cloth 16 inside the installation box 61, the installation box 61 is removed from the protective cover 6, and the release handle 39 is pulled horizontally by manpower. The release handle 39 drives the locking rod 42 through the first connecting column 40 and the second connecting column 41 to overcome the elastic force of the pressing spring sheet 30 and rotate, and move out from the wheel groove of the locking ratchet 22. At this time, the active roller 17 can rotate in the opposite direction. At the same time, the damping column 25 on the side of the extension rod 26 does not contact the rotating shaft of the driven roller 18, and the rotation resistance of the driven roller 18 is reduced. The worker rotates the driven roller 18 through the hemispherical hole 29 of the bottom plate 28, wraps the cleaning cloth 16, and releases the old cleaning cloth 16, so that the user can fully clean the cleaning cloth 16.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
