Description

Technical Field

[0001] This utility model relates to the field of access control equipment technology, and more specifically to a face recognition access control device with a protective structure. Background Technology

[0002] The facial recognition access control system is a facial recognition access control and attendance product that can be used offline or online. It is positioned in the mid-to-high-end access control and attendance market and replaces card-swiping and fingerprint access control and attendance machines on the market.

[0003] Currently, facial recognition access control equipment can be divided into indoor and outdoor environments based on the installation space. For outdoor facial recognition access control equipment installed in the open air, it is exposed to rain and strong sunlight during use. Under these conditions, the equipment will age faster and reduce the accuracy and lifespan of the internal light-sensing components.

[0004] In view of this, the present invention proposes a face recognition access control device with a protective structure to solve this problem. Utility Model Content

A light intensity sensor and an infrared sensor are fixedly installed on the front and bottom sides of the face recognition access control device, respectively. The positions of the light intensity sensor and the infrared sensor correspond to the recognition window.

[0007] Furthermore, a limiting slide bar is fixedly installed on the inner wall of the protective box, and the movable seat is slidably connected to the limiting slide bar.

[0008] As a further description of the above technical solution: by setting a limit slide bar, the stability of the moving seat during movement can be improved.

[0009] Furthermore, a balance slide bar is fixedly installed on the top of the connecting box, and the balance slide bar is slidably connected to the connecting plate.

[0011] Furthermore, the face recognition access control device and the connecting box are movably connected, and an angle adjustment component is provided between the connecting box and the face recognition access control device. The angle adjustment component includes a horizontal shaft rotatably connected to the surface of the connecting box. The face recognition access control device is fixedly installed on the surface of the horizontal shaft, and a second electric push rod for driving the horizontal shaft to deflect to adjust the pitch angle of the face recognition access control device is embedded on the surface of the connecting box. The telescopic end of the second electric push rod extends into the interior of the connecting box and is fixedly installed with a rack. A gear plate is fixedly installed on the surface of the horizontal shaft, and the rack meshes with the gear plate.

[0012] As a further description of the above technical solution: By setting an angle adjustment component, when the face recognition access control device is working, if no face is recognized within a certain period of time, the second electric push rod can be automatically controlled to extend and retract to drive the rack to move.

Detailed Implementation

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The face recognition access control device with protective structure involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1 to 5 This utility model provides a face recognition access control device with a protective structure, including a protective box 1, a column 18 fixedly installed at the bottom of the protective box 1, a base 19 welded to the bottom of the column 18, and mounting holes 20 opened on the surface of the base 19.

A threaded screw 2 is rotatably connected to the top of the inner cavity 6. A forward and reverse motor 3 is fixedly installed on the back of the protective box 1. The output shaft of the forward and reverse motor 3 is coaxially fixedly connected to the end of the threaded screw 2. A movable seat 4 is threadedly connected to the surface of the threaded screw 2.

[0033] A connecting plate 5 is fixedly installed at the bottom of the movable base 4. A first electric push rod 7 is fixedly installed at the bottom of the connecting plate 5. A connecting box 8 is fixedly installed at the telescopic end of the first electric push rod 7. A face recognition access control device 9 is installed on the surface of the connecting box 8. The face recognition access control device 9 is connected to the external access control system. A light intensity sensor 10 and an infrared sensor 11 are fixedly installed on the front and bottom sides of the face recognition access control device 9, respectively. The light intensity sensor 10 and the infrared sensor 11 correspond to the positions of the recognition window.

[0034] When the face recognition access control device with a protective structure is installed and used outdoors, the face recognition access control device 9 is protected from rain by the protective box 1.

[0035] It is worth noting that when the entire equipment is idle, the light intensity sensor 10 senses the external light intensity and controls the face recognition access control device 9 to be located in a high and deep position inside the protective box 1 to avoid damage to the light sensing element caused by strong external light when idle. When working, the infrared sensor 11 senses moving objects in the vicinity and controls the forward and reverse motor 3 to drive the threaded screw 2 to rotate, so that the moving base 4 and the face recognition access control device 9 move forward. At the same time, the first electric push rod 7 extends and drives the face recognition access control device 9 to move down and be exposed from the recognition window position, so as to facilitate the face recognition operation for visitors.

[0036] A limiting slide rod 12 is fixedly installed on the inner wall of the protective box 1, and the movable seat 4 is slidably connected to the limiting slide rod 12.

[0042] The telescopic end of the second electric push rod 15 extends into the interior of the connecting box 8 and is fixedly installed with a rack 16. A gear plate 17 is fixedly installed on the surface of the horizontal shaft 14, and the rack 16 meshes with the gear plate 17.

[0043] It is worth noting that by setting an angle adjustment component, when a face is not recognized within a certain period of time during the operation of the overall face recognition access control device, the second electric push rod 15 can be automatically controlled to extend and retract to drive the rack 16 to move. Based on the meshing of the rack 16 and the toothed disc 17, the horizontal axis 14 can be driven to deflect to slightly adjust the tilt angle of the face recognition access control device 9, so as to adapt to people of different heights and make it highly adaptable.

[0047] Furthermore, by setting ventilation grilles 22, the ventilation inside the protective box 1 can be ensured to guarantee the heat dissipation of the face recognition access control device 9. By setting heat-conducting fins 23, the heat exchange speed between the protective box 1 and the external environment can be improved, ensuring the safe use of the face recognition access control device 9.
