[0002] With the rapid development of artificial intelligence technology, facial recognition technology has been widely used in many fields such as security, access control, and attendance.

[0003] Existing AI facial recognition devices face significant challenges due to varying user heights and positions across different usage scenarios. Most facial recognition devices have fixed camera heights, limiting their flexibility and making it difficult to accurately capture facial information in certain situations. This reduces recognition accuracy and efficiency. Furthermore, facial recognition cameras are constantly exposed to the external environment, making them susceptible to dust, moisture, and impacts, which shortens their lifespan and affects recognition accuracy. For instance, in outdoor environments or dusty locations, camera lenses quickly become covered in dust, resulting in blurry facial images and impacting recognition performance. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses an artificial intelligence facial recognition device. The technical solution adopted is as follows: a base plate is included, a column is fixedly installed on the top of the base plate, a top plate is fixedly installed on the top of the column, a control module is fixedly installed on the bottom of the top plate, a height adjustment mechanism is installed on the column, a facial recognition module is fixedly connected to the height adjustment mechanism, and a camera protection mechanism is installed on the facial recognition module.

[0005] The facial recognition module includes a camera, a housing, and a display screen. The camera and the display screen are respectively fixedly installed in two grooves on the side of the housing.

[0006] The camera protection mechanism includes a rack, a rotating rod, a protective plate, gears, a protective motor, and a guide plate.

[0007] As a preferred embodiment of this utility model, the height adjustment mechanism includes a laser ranging module, a moving block, a slide groove, a lead screw, and an adjusting motor. The laser ranging module is fixedly installed at the bottom of one end of the top plate. The slide groove is formed on the side of the column, and the side walls at both ends of the slide groove are rotatably connected to the two ends of the lead screw. One end of the lead screw passes through a screw hole on the side of the moving block.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses a laser ranging module to measure the distance to a target object in real time. When users of different heights approach, the control module controls the adjusting motor based on the feedback from the laser ranging module, causing the lead screw to rotate and the moving block to move up and down within the slide groove. This adjusts the height of the facial recognition module, ensuring that the camera is in the optimal shooting position regardless of the user's height, accurately capturing facial information and greatly improving the accuracy and efficiency of recognition. This adapts to diverse usage needs in different scenarios. When the facial recognition device is not in use, the control module can start the protective motor, causing the rotating rod and the gear fixed on the rotating rod to rotate. Because the gear meshes with the rack on the back of the protective plate, the protective plate can slide along the side of the outer shell under the guidance of the guide plate, effectively preventing damage to the camera from dust, moisture, and collisions, extending the camera's service life, and ensuring that the camera can always clearly capture facial images during long-term use, guaranteeing the accuracy of facial recognition.

[0020] Example 1

[0021] like Figures 1 to 5As shown, this utility model discloses an artificial intelligence facial recognition device. The technical solution includes a base plate 1, a column 2 fixedly installed on the top of the base plate 1, and fixing holes 10 at the four corners of the top of the base plate 1. A top plate 3 is fixedly installed on the top of the column 2, and a control module 6 is fixedly installed on the bottom of the top plate 3. A height adjustment mechanism 5 is installed on the column 2. The height adjustment mechanism 5 includes a laser ranging module 51, a moving block 52, a sliding groove 53, a lead screw 54, and an adjusting motor 55. The laser ranging module 51 is fixedly installed at the bottom of one end of the top plate 3. The sliding groove 53 is opened on the side of the column 2, and the side walls at both ends of the sliding groove 53 are respectively connected to the lead screw. The two ends of 54 are rotatably connected. One end of the lead screw 54 passes through the screw hole on the side of the moving block 52. The moving block 52 is slidably installed in the slide groove 53. The end of the moving block 52 located outside the slide groove 53 is fixedly connected to the back of the outer shell 42. The adjusting motor 55 is fixedly installed in the cavity at the lower end of the column 2. The output shaft of the adjusting motor 55 is fixedly connected to one end of the lead screw 54. The laser ranging module 51 and the adjusting motor 55 are electrically connected to the control module 6. A face recognition module 4 is fixedly connected to the height adjustment mechanism 5. A camera protection mechanism 7 is installed on the face recognition module 4. Fill lights 9 are fixedly installed in the two grooves on the side of the column 2. The supplementary lights 9 are located on both sides of the face recognition module 4. These lights provide ample illumination to the face, enabling the camera 41 to clearly capture facial features and enhancing the device's adaptability and stability in complex lighting environments. The laser ranging module 51 measures the distance to the target object in real time. When users of different heights approach, the control module, based on feedback from the laser ranging module, controls the adjusting motor 55 to rotate the lead screw 54, causing the moving block 52 to move up and down within the slide groove 53. This adjusts the height of the face recognition module 4, ensuring the camera is in the optimal shooting position regardless of the user's height. Accurately capturing facial information greatly improves the accuracy and efficiency of recognition, adapting to diverse usage needs in different scenarios; the facial recognition module 4 includes a camera 41, a housing 42, and a display screen 43. The camera 41 and the display screen 43 are fixedly installed in two grooves on the side of the housing 42, respectively. A light shield 8 is fixedly installed on the top of the housing 42. The light shield 8 is U-shaped and located above the camera 41. The light shield 8 can effectively block light from directly shining on the lens of the camera 41, avoiding facial reflection caused by strong light, making the captured facial image clearer, and improving the success rate of facial recognition in strong light environments;The camera protection mechanism 7 includes a rack 71, a rotating rod 72, a protective plate 73, a gear 74, a protective motor 75, and a guide plate 76. The guide plate 76 is L-shaped, and two guide plates 76 are provided. The two guide plates 76 are fixedly installed on the side of the upper end of the housing 42. The protective plate 73 is slidably installed inside the two guide plates 76, located outside the camera 41. Two racks 71 are fixedly installed on the back of the protective plate 73. A through groove is provided on the side wall of the upper end of the housing 42 to mate with the two racks 71, extending to the outer side of the housing 42. The protective motor 75 is fixedly installed in a groove on the inner wall of the housing 42. The output shaft of the protective motor 75 is fixedly connected to one end of the rotating rod 72, and the other end of the rotating rod 72 is rotatably connected to the other inner wall of the housing 42. Next, two gears 74 are fixedly installed on the rotating rod 72. The two gears 74 mesh with two racks 71 respectively. The camera 41, display screen 43, and protective motor 75 are electrically connected to the control module 6. When the facial recognition device is not in use, the control module 6 can control the protective motor 75 to start, driving the rotating rod 72 and the gears 71 fixed on the rotating rod 72 to rotate. Because the gears 71 mesh with the racks 71 on the back of the protective plate 73, the protective plate 73, guided by the guide plate 76, can slide along the side of the outer shell 42, shielding the camera 41. This effectively prevents damage to the camera 41 from dust, moisture, and impacts, extending the service life of the camera 41 and ensuring that the camera 41 can always clearly capture facial images during long-term use, guaranteeing the accuracy of facial recognition.

[0022] The working principle of this utility model is as follows: In use, the base plate 1 is fixed in the position of use through the fixing hole 10. When the external power supply is connected, when people perform facial recognition, they will stand on the base plate 1 and be located in front of the facial recognition module 4. At this time, the laser ranging module 51 starts to measure the distance to the target person and transmits the measurement data to the control module 6 in real time. The control module 6 controls the adjustment motor 55 to work according to the received distance data, so that its output shaft drives the lead screw 54 to rotate. The rotation of the lead screw 54 causes the moving block 52 to move up and down along the slide groove 53. The moving block 52 drives the facial recognition module 4 to move up and down as a whole, so that the camera 41 is at the optimal shooting height for facial recognition.

[0023] During the process of laser ranging module 51 detecting people's height, control module 6 automatically controls the protective motor 75 to start. Its output shaft drives the rotating rod 72 to rotate, which in turn drives the gear 74 to rotate. The rotation of gear 74 causes the rack 71, which meshes with it, to move linearly. Since the protective plate 73 is fixedly connected to the rack 71, and the protective plate 73 can only slide along the side of the outer shell 42 under the guidance of the two L-shaped guide plates 76, when the rack 71 moves, the protective plate 73 will slide along the side of the outer shell 42 under the guidance of the guide plates 76, thereby exposing the camera 41. Conversely, after facial recognition is completed, the protective motor 75 rotates in the opposite direction, causing the protective plate 73 to move downwards and block the camera 41. In this way, when the device is not in use, the protective plate 73 can block the camera 41, effectively preventing damage to the camera 41 from dust, moisture, collisions, etc., extending the service life of the camera 41, and ensuring the accuracy of facial recognition.
