[0016] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.
[0017] like Figures 1-3 As shown, the access control device according to an embodiment of this application includes a housing 1, an identification module 5, an NFC module 4, and a sign cover. The housing 1 has a mounting cavity and a viewing window 1111 communicating with the mounting cavity. The identification module 5 is installed in the mounting cavity and includes a camera 51 opposite to the viewing window 1111. The camera 51 is used to identify QR codes and faces. The NFC module 4 is installed in the mounting cavity. The sign cover is connected to the housing 1 and has a first mark 23 opposite to the identification module 5 and a second mark 31 opposite to the NFC module 4.
[0018] According to the access control device of this application embodiment, an identification module 5 and an NFC module 4 are installed inside the housing 1. The camera 51 of the identification module 5 is positioned opposite the window 1111 of the housing 1. The camera 51 can identify QR codes and faces through the window 1111 to complete the QR code identification and face recognition functions. At the same time, the NFC module 4 can also identify NFC on the work card or mobile phone to complete the NFC identification function. Thus, the access control device can have three identification functions at the same time, which improves its functionality. Combined with the first mark 23 on the housing 1 opposite to the identification module 5 and the second mark 31 opposite to the NFC module 4, users can easily use appropriate means to quickly open the access door controlled by the access control device in enterprise scenarios to achieve the purpose of fast passage.
[0019] It should be noted that in this embodiment of the access control device, the camera 51 of the identification module 5 can also identify only QR codes or only faces as needed to meet different usage requirements. In addition, the window 1111 is a through hole penetrating the wall of the housing 1. After the sign cover is connected to the housing 1, the window 1111 is closed to ensure the waterproof sealing performance of the mounting cavity and to ensure the service life of the internal NFC module 4 and identification module 5.
[0020] In some embodiments of this application, the camera 51 and the window 1111 are arranged along a first direction, and the identification module 5 and the NFC module 4 are arranged along a second direction, which is perpendicular to the first direction.
[0021] At this time, the sensing area on the housing 1 that is opposite to the identification module 5 and the sensing area that is opposite to the NFC module 4 are located on the same side of the housing 1 and arranged along the second direction, such as both being located on one side of the housing 1 in the first direction. Thus, the size of the housing 1 in other directions can be designed to be smaller, the access control device is smaller, and the manufacturing cost is lower.
[0022] Specifically, the first direction is the thickness direction and the front-to-back direction of the housing 1, and the second direction is the length direction of the housing 1. The front surface of the housing 1 forms the two sensing areas mentioned above. Depending on the specific scenario, the second direction can be the left-to-right direction of the housing 1 for better application in scenarios with wider walls, or it can be the up-to-down direction of the housing 1 for better application in scenarios with narrower walls.
[0023] It should be noted that, such as Figure 2 and Figure 3 As shown, when the second direction is left-right, the NFC module 4 is located to the right of the identification module 5; when the second direction is up-down, the identification module 5 is located above the NFC module 4.
[0024] In some embodiments of this application, such as Figures 1-3 As shown, the sign cover includes a first cover body 2 and a second cover body 3. The first cover body 2 and the second cover body 3 are arranged along a second direction. The first cover body 2 is provided with a first mark 23, and the second cover body 3 is provided with a second mark 31.
[0025] That is, the first cover 2 and the second cover 3 are set independently. When different first marks 23 or second marks 31 are needed according to different scenario requirements, only the first cover 2 with the new first mark 23 or the second cover 3 with the new second mark 31 needs to be replaced. The replacement of the first mark 23 and the second mark 31 is more flexible and the replacement cost is lower.
[0026] Specifically, the different scenario requirements mentioned above include the following: recognition module 5 only recognizes QR codes, recognition module 5 only recognizes faces, recognition module 5 recognizes both QR codes and faces simultaneously, and when the first mark 23 and the second mark 31 are text, the corresponding language is used according to the country or region of application. Furthermore, the first mark 23 and the second mark 31 can be paint printed on the first cover 2 and the second cover 3, or they can be grooves machined on the first cover 2 and the second cover 3.
[0027] In some embodiments of this application, such as Figure 1As shown, the housing 1 includes a front shell 11 and a rear cover 12. The front shell 11 and the rear cover 12 are detachably connected and surround each other to form a mounting cavity. The front shell 11 includes a front panel 111 opposite to the first direction, and a viewing window 1111 is provided on the front panel 111.
[0028] The detachable connection between the front shell 11 and the rear cover 12 facilitates the secure installation of the identification module 5 and the NFC module 4 within the mounting cavity. At the same time, placing the viewing window 1111 on the front panel 111 of the front shell 11 makes it easier for users to perform QR code recognition and face recognition while facing the access control device.
[0029] Specifically, the front cover 11 and the rear cover 12 are connected by multiple threaded parts, and the identification module 5 and the NFC module 4 are installed on the front side of the rear cover 12 by threaded parts. The first cover 2 and the second cover 3 are both connected to the front side of the front panel 111 and are arranged at intervals along the second direction.
[0030] In some embodiments of this application, each of the first cover 2 and the second cover 3 is bonded and / or snapped to the front panel 111.
[0031] That is, the first cover 2 and the second cover 3 can be bonded to the front panel 111, so that the connection between the first cover 2 and the second cover 3 and the front panel 111 is convenient and reliable. The first cover 2 and the second cover 3 can also be snapped onto the front panel 111, thereby making it easy to disassemble and assemble the first cover 2 and the second cover 3, and facilitating the replacement of the first cover 2 and the second cover 3.
[0032] It should be noted that the first cover 2 and the second cover 3 can also be connected to the front panel 111 via threaded parts.
[0033] In some embodiments of this application, such as Figure 1 As shown, the outer surface of the front panel 111 is provided with a first limiting groove 1112 and a second limiting groove 1113 arranged along the second direction. The first cover 2 is fitted in the first limiting groove 1112 and the second cover 3 is fitted in the second limiting groove 1113.
[0034] The setting of the first limiting groove 1112 and the second limiting groove 1113 effectively achieves relative fixation of the first cover 2 and the second cover 3 in directions other than the first direction. Combined with the bonding and / or snap-fitting of the first cover 2 and the second cover 3 with the front panel 111, the reliability of the connection between the first cover 2 and the second cover 3 and the front panel 111 is further guaranteed.
[0035] Specifically, the first limiting groove 1112 and the second limiting groove 1113 are both square grooves and are arranged at intervals along the second direction, and the first cover 2 and the second cover 3 are both square plates with rounded corners.
[0036] In some embodiments of this application, the NFC module 4 includes an NFC chip and an NFC coil. The NFC chip is mounted on the back cover 12, and the NFC coil is communicatively connected to the NFC chip.
[0037] When a work card or mobile phone with an NFC coil approaches or touches the second cover 3, the NFC coil in the NFC module 4 is sensed and transmits data to the NFC chip to complete NFC identification.
[0038] Specifically, the NFC chip is mounted on the back cover 12 via a threaded fitting, and the NFC coil is located on the side of the NFC chip facing the front panel 111, so that the NFC coil is close to the front panel 111. The back cover 12 is provided with a cable exit hole, through which the communication cable connected to the NFC chip protrudes from the housing 1.
[0039] In some embodiments of this application, the identification module 5 further includes an electronic control board, which is mounted on the rear cover 12, and the camera 51 is mounted on the side of the electronic control board facing the front panel 111.
[0040] The electronic control board of the identification module 5 can receive and process the QR code or facial data identified by the camera 51, and control the access door to open via a communication cable after identification is completed. At this time, the identification module 5 and the NFC module 4 are set up independently, which facilitates the installation and replacement of the identification module 5 and the NFC module 4 in the mounting cavity.
[0041] Specifically, the control board is connected to the rear cover 12 via a threaded component, and the communication cable electrically connected to the control board protrudes out of the housing 1 through the cable hole of the rear cover 12.
[0042] In some embodiments of this application, such as Figure 1 As shown, the first cover 2 includes a light-transmitting plate 21 and a light-shielding layer 22. The light-transmitting plate 21 is connected to the housing 1 and closes the viewing window 1111. The light-shielding layer 22 is disposed on the inner or outer surface of the light-transmitting plate 21. On the projection plane perpendicular to the first direction, the projection of the light-shielding layer 22 does not overlap with the projection of the viewing window 1111. The light-shielding layer 22 is provided with a first mark 23.
[0043] The portion of the light-transmitting panel 21 that is not obstructed by the light-shielding layer 22 is opposite to the viewing window 1111, so that the camera 51 can recognize the QR code and face through the viewing window 1111 and the light-transmitting panel 21. The light-shielding layer 22 improves the aesthetic appearance of the first cover 2 and facilitates the placement of a prominent first mark 23 for easy identification by the user.
[0044] Specifically, without affecting the camera 51's ability to recognize QR codes and faces, circular outlines can be set on the light-transmitting layer to remind users to accurately align the QR code and face with the viewing window 1111, thereby improving the recognition efficiency of the recognition module 5 in recognizing QR codes and faces.
[0045] Furthermore, the light-transmitting plate 21 is a colorless and transparent plastic plate, and the light-shielding layer 22 is a black coating that can be coated or adhered to the inner or outer surface of the light-transmitting plate 21. The light-shielding layer 22 blocks the edge of the light-transmitting plate 21. Alternatively, the first cover 2 in this embodiment may also include a connected light-transmitting part and a light-shielding part, with the light-shielding part connected to the outer edge of the light-transmitting part. The second cover 3 is an opaque plastic plate.
[0046] In some embodiments of this application, the first mark 23 and the second mark 31 include at least one of an image and text.
[0047] Images and / or text can more intuitively represent the functions of the corresponding areas of the first cover 2 and the second cover 3, effectively improving the recognizability of the functional areas of the access control equipment and making it easier for users to quickly identify them, so as to achieve the purpose of rapid passage in enterprise scenarios.
[0048] like Figure 2 and Figure 3 As shown, the first mark 23 can be a text mark such as "Please scan the code", "Please scan the face", or "Please scan the code or scan the face", and the second mark 31 can be a combination of a text mark such as "Please swipe the card" and an image mark containing card and finger features.
[0049] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
