Technical Field

[0001] The utility model relates to the technical field of access control, and particularly relates to an intelligent access control device. Background Art

[0002] Intelligent access control devices are widely installed at the entrances of buildings such as office buildings and dormitories. They can quickly identify the identities of visitors and open the baffle for visitors to pass through. With the increasing popularity of intelligent recognition technology, the intelligence level of intelligent access control devices is also getting higher and higher, and generally integrates functions such as face recognition and ID card recognition.

[0003] In the prior art, the internal transmission structure of the intelligent access control device is quite complex, and the quality of its rocker is relatively large, resulting in a slow swinging speed of the baffle, making the opening and closing process of the baffle not fast enough, which affects the passing speed of personnel. In addition, the disassembly and assembly of its housing cover are relatively complex and cumbersome. Once the internal components of the access control device fail and need to be repaired, it is often difficult to easily remove the cover, delaying the repair of the access control device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an intelligent access control device, which can improve the swinging speed of the baffle, make the opening and closing process of the baffle faster, and in addition, its cover can be easily removed for easy maintenance.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0038] Specifically, the inner side edges of the lower parts of the rocker 27 and the baffle 28 are fixedly connected.

[0039] Specifically, see Figure 2 、 Figure 3 、 Figure 7 、 Figure 8, the housing includes a bottom frame 12 and a top frame 13. Both the bottom frame 12 and the top frame 13 are in the shape of a shuttle. Both ends and both sides of the middle part of the bottom frame 12 are fixedly connected to the top frame 13 through connecting vertical plates 11. A slit 111 is provided on the inner connecting vertical plate 11. A cover plate 14 is provided between two adjacent connecting vertical plates 11. A plurality of connecting buckles 141 are fixedly connected to the inner side of the bottom edge of the cover plate 14. A hanging strip 121 is fixedly connected to the edge of the bottom frame 12.

[0042] The working principle of the intelligent access control device of the present utility model is as follows:

[0043] The camera 321 of the screen 32 can perform face recognition on visitors, and the screen 32 can display relevant information. Visitors can also swipe an access card at the access card sensor 33 to pass authentication, or swipe a temporarily authorized ID card at the ID card sensor 34 to pass authentication.

[0044] After passing authentication, refer to Figure 5 , the opening and closing motor 24 drives the upper rotating shaft 251 to rotate, thereby driving the crank 26 to swing downward, so that the head of the lever 261 slides downward relative to the annular notch 2721, thereby driving the rocker 27 and the baffle 28 to swing inward, so that the baffle 28 retracts into the housing.

[0045] The transmission chain structure from the opening and closing motor 24 to the baffle 28 is simple, with high transmission efficiency, fast corresponding speed, and the rocker 27 is provided with a lower long slot 273, so that the mass of the rocker 27 is lighter. Therefore, the rocker 27 can swing at a faster speed, making the opening and closing process of the baffle 28 more rapid and ensuring the passing speed of personnel.

[0046] A hanging strip 121 is fixedly connected to the edge of the bottom frame 12. The connecting buckle 141 can be hung on the hanging strip 121. A plurality of lock cores 142 are provided at the upper side edge of the cover plate 14. A rotating lock hook 1421 is provided at the inner end of the lock core 142. The top frame 13 is provided with a plurality of longitudinal bars 131 and transverse bars 132. The rotating lock hook 1421 can rotate to hook a certain transverse bar 132, so as to facilitate the loading and unloading of the cover plate 14, and thus can quickly repair components such as the opening and closing motor 24.

[0047] A proximity sensor 143 is embedded in the upper part of the cover plate 14. The proximity sensor 143 is strip-shaped and horizontally arranged. The proximity sensor 143 is electrically connected to the circuit board 31. During the process of a visitor passing through the access control, the two pairs of proximity sensors 143 cooperate with each other. When it is determined that the visitor has passed through the slit 111, the opening and closing motor 24 will drive the baffle 28 to turn out and reset to avoid accidentally clamping the visitor.

Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention.
