Description

Technical Field

[0001] The utility model relates to the technical field of access control, in particular to a multi-modal access control device. Background Art

[0002] A multimodal access control device is usually a type of access control device that supports multiple authentication methods. For example, it may support multiple authentication methods such as passwords, fingerprint recognition, facial recognition, or IC cards. This type of device can ensure that only authorized personnel can enter specific areas through access control and improve access control security. In addition, multimodal access control devices can also record the identity information and time of people entering and leaving, helping companies or organizations to conduct access control management and statistical analysis.

[0003] However, the traditional multimodal access control devices currently on the market are generally fixed at a certain position on the wall at a fixed height when in use. When the access control adopts iris recognition or facial recognition technology, the user's iris or face needs to be located at a specific collection position to better collect the image. So for people of different heights, when using it, shorter people may need to tiptoe or use external objects to increase their height to align the recognizer, while taller people may need to bend over or lower their heads to make their face and the recognizer on the same level. Such adjustment actions may cause certain inconveniences to body posture and user experience.

[0004] Therefore, it is necessary to provide a multimodal access control device to solve the above technical problems. Utility Model Content

[0029] The working principle of the utility model is:

[0030] Reference Figures 1 to 5When in use, the specific structure of the access control body 3 can refer to the prior art, which can be easily implemented by those skilled in the art. The electrical components appearing in this application are all externally connected to the power supply and the control switch when in use. When the access control body 3 is in use, the motor 11 can be controlled by the switch to start working. The driving end of the motor 11 drives the adjusting screw rod 4 to rotate. By adjusting the threaded transmission between the screw rod 4 and the adjusting block 9 and the sliding relationship between the adjusting block 9 and the limiting groove 5, the adjusting block 9 can be stably moved vertically. The movement of the adjusting block 9 drives the fixing frame 10 to move. The movement of the fixing frame 10 drives the electric telescopic rod 6 to move. The connecting plate 16 moves with the fixing frame 10. The movement of the connecting plate 16 drives the access control body 3 to move. Therefore, the vertical adjustment effect of the access control body 3 is achieved through the drive of the motor 11, so it is suitable for people of different heights. When using the access control body 3, the user can adjust the vertical position of the access control body 3 so that the user's face and the recognition part on the access control body 3 are on the same horizontal line. The user can easily be at the collection position of the access control body 3, which is convenient for the access control body 3 to quickly recognize the user and improve the convenience of people's use. At the same time, when the vertical height of the access control body 3 is adjusted, the electric telescopic rod 6 can be controlled by the switch to start working, the extension of the driving end of the electric telescopic rod 6, and the angle of the connecting plate 16 can be adjusted through the hinged relationship between the connecting plate 16 and the fixing frame 10. Therefore, the inclination angle of the access control body 3 can be adjusted by driving the electric telescopic rod 6, thereby improving the adjustment range of the access control body 3, making it more convenient for users of different heights to use, improving the applicability of the device, and meeting the use needs of people of different heights.

[0031] Reference Figures 1 to 5When in use, the door control body 3 is inevitably covered with dust. When dust is found on the front of the door control body 3, the cleaning frame 12 can be directly pulled, and the movement of the cleaning frame 12 drives the limit block 24 to slide horizontally on the slide groove 17. The movement of the cleaning frame 12 drives the limit frame 14 to move through the slider 15, and the movement of the limit frame 14 drives the cleaning cloth 13 to move. When the cleaning cloth 13 moves to the front of the door control body 3, the front of the door control body 3 can be directly wiped to clean the dust on the door control body 3 and keep the door control body 3 clean. The cleaning structure on the front of the connecting plate 16 is convenient for quickly cleaning the dust on the door control body 3. There is no need to manually clean the door control body 3 with a rag. The practicability is high. After being wiped many times, the cleaning cloth 13 will adhere to dust. When there is a large amount of dust and the cleaning cloth 13 needs to be replaced, the limiting frame 14 can be directly pressed. The movement of the limiting frame 14 drives the slider 15 to slide on the positioning groove 25 and squeeze the spring 26, so that the limiting frame 14 loses the squeezing effect on the cleaning cloth 13 by cooperating with the inner wall of the cleaning frame 12, and the cleaning cloth 13 can be easily removed from the limiting frame 14, and then a new cleaning cloth 13 can be replaced and wrapped, and then the limit on the limiting frame 14 is slowly released. Under the elastic action of the spring 26, the limiting frame 14 is moved closer to the front side of the inner wall of the cleaning frame 12 through the slider 15, and the cleaning cloth 13 is firmly pressed on the outer surface of the limiting frame 14. Therefore, the disassembly and assembly structure of the cleaning cloth 13 is simple and easy to operate, which is convenient for regular and quick replacement of the cleaning cloth 13 in use, convenient for people to use, and ensures the cleaning effect of the access control body 3.
