[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figure 1-5 As shown, a smart access control system includes a fixed housing 1 and a door 2. The fixed housing 1 is U-shaped, and the door 2 is located inside the fixed housing 1. One side of the fixed housing 1 is rotatably connected to the door 2. Vertically distributed lead screws 7 are rotatably connected to both sides inside the fixed housing 1. Slider 8, which is slidably connected to the inner wall of the fixed housing 1, is threaded onto the lead screws 7. Two through slots 6 are symmetrically distributed about the slider 8 on opposite inner sides of the fixed housing 1. A pin 11 is rotatably connected through the side of the slider 8. Cleaning slot plates 5 are fixed to the pin 11 on both sides of the slider 8. The slot openings of the cleaning slot plates 5 face the door 2. A cleaning plate 14 for cleaning the door 2 is inserted into the slot of the cleaning slot plate 5. An electric push rod 15 is fixedly connected to the slot of the cleaning slot plate 5. The telescopic end of the electric push rod 15 is fixed to the cleaning plate 14. Connecting plates 16 are fixedly connected to the top of the two cleaning slot plates 5 located on both sides of the slider 8.

[0020] In this technical solution, a fixed housing 1 is set up to install the door 2 and the cleaning components. The cleaning components include a cleaning groove plate 5 and a lead screw 7. A slider 8 and a lead screw 7 are set up. The slider 8 is raised and lowered by the rotation of the lead screw 7, which in turn raises and lowers the cleaning groove plate 5. The cleaning plate 14 is used to wipe the surface of the door 2. In the non-working state, the cleaning groove plate 5 is in a vertically distributed state, which drives the cleaning plate 14 to be located inside the fixed housing 1. In the working state, the cleaning groove plate 5 is rotated to a horizontal state. Then, the electric push rod 15 extends to drive the cleaning plate 14 to approach the door 2 and stick tightly to the door 2. A connecting plate 16 is set up to fix the two cleaning groove plates 5 to enhance the structural stability.

[0021] like Figure 4 As shown, a first motor 10 is fixedly connected to the bottom of the slider 8. Gears 12 are fixedly connected to one end of the main shaft and the pin 11 of the first motor 10, and the two gears 12 mesh.

[0022] In this technical solution, a first motor 10 is set to drive the gear 12 to rotate. Under the drive of the two meshing gears 12, the pin shaft 11 is driven to rotate, which in turn drives the cleaning tank plate 5 to rotate.

[0023] like Figure 2 As shown, a second motor 9 is fixedly connected to the bottom of the fixed housing 1. The main shaft of the second motor 9 is fixed to one of the lead screws 7. Synchronous pulleys 13 are sleeved on the outside of the two lead screws 7. The two synchronous pulleys 13 are driven by a synchronous belt.

[0024] In this technical solution, a second motor 9 is set to drive the lead screw 7 to rotate. Through the transmission of the synchronous pulley 13 and the synchronous belt, the two lead screws 7 rotate synchronously, thereby driving the slider 8 to rise and fall, which in turn drives the cleaning trough plate 5 to rise and fall. The cleaning plate 14, which is in close contact with the door body 2, wipes the surface of the door body 2, thereby cleaning the door body 2.

[0025] like Figure 1 As shown, a mounting base 4 is fixedly connected to one end of the top of the fixed housing 1, and a face recognition device 3 is installed on the mounting base 4.

[0026] like Figure 2 As shown, a pin 18 is fixedly connected to one side of the door body 2, and the door body 2 is rotatably connected to the fixed box 1 through the pin 18. A third motor 17 is fixedly connected to the other side of the top of the fixed box 1, and the main shaft of the third motor 17 is fixed to the pin 18.

[0027] In this technical solution, a third motor 17 is set to drive the bolt 18 to rotate, thereby driving the door body 2 to rotate when the bolt 18 rotates.

[0028] Working principle: Personnel complete identity verification in front of the face recognition device 3 on the top of the fixed box 1. After successful verification, the third motor 17 drives the pin 18 to rotate, causing the door 2 to rotate around the fixed box 1 and open. After personnel pass through, the door automatically resets and closes. During cleaning, the first motor 10 drives the gear 12 to mesh and drive the pin 11 to rotate, rotating the cleaning tray 5 from a vertical position to a horizontal extension. The electric push rod 15 extends and pushes the cleaning plate 14 to press against the surface of the door 2. The second motor 9 drives the lead screw 7 to rotate, and through the synchronous pulley 13 and synchronous belt, the lead screws 7 on both sides rotate synchronously, causing the slider 8 to slide vertically along the inner wall of the fixed box 1. The cleaning plate 14 moves up and down with the cleaning tray 5 to wipe the surface of the door 2. After cleaning, the electric push rod 15 retracts, causing the cleaning plate 14 to retract into the cleaning tray 5. The first motor 10 drives the cleaning tray 5 to rotate to a vertical position, and it is hidden inside the fixed box 1 along with the slider 8.

[0029] Furthermore, the first motor 10 can be a stepper motor, the second motor 9 can be a three-phase asynchronous motor, and the third motor 17 can be a DC motor.

[0030] The wiring diagrams of the first motor 10, the second motor 9, the third motor 17, and the electric push rod 15 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring arrangements of the first motor 10, the second motor 9, the third motor 17, and the electric push rod 15 will not be explained in detail.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
