Description

Technical Field

[0001] This utility model relates to the technical field of facial recognition, and more specifically, to a facial recognition device. Background Technology

[0002] Facial recognition technology, a biometric identification method based on computer vision, achieves identity verification and recognition by collecting facial feature data. With breakthroughs in neural network algorithms, this technology has been deeply integrated into modern security monitoring systems, smart terminal devices, and financial payment systems. Typical applications include airport security gates, smart building access control systems, and mobile payment terminals. In the public safety sector, this technology can effectively build personnel access control systems; in smart city construction, it can be integrated into city-level identity verification networks; and in the fintech field, it can be used as a biometric key for payment verification.

[0003] Existing facial recognition devices typically place the facial recognition machine in various indoor and outdoor working environments at a fixed height, relying solely on a wide-angle camera and the angle of the facial recognition machine itself to identify people. At the same time, due to the accumulation of static electricity generated by the screen during long-term operation, dust and small objects in the air will float and adhere to the screen of the facial recognition machine, resulting in a decrease in the clarity of the images captured by the camera and displayed on the screen, thus affecting the recognition effect of facial recognition.

[0032] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0033] like Figure 1 and Figure 2 , Figure 3 , Figure 4 As shown, a face recognition device according to one embodiment of the present invention includes:

[0034] The support frame 100 has an internal adjustment and lifting assembly 200. The adjustment and lifting assembly 200 includes a slide groove 201 disposed in the support frame 100. A lifting plate 202 is slidably disposed in the slide groove 201. An identification display screen 101 is disposed at the end of the lifting plate 202.

[0035] The mobile cleaning component 300 is disposed on the identification display screen 101 and includes a guide slot frame 301 disposed on both sides of the identification display screen 101, and a first sliding block 302 and a second sliding block 303 respectively slidably disposed in the guide slot frame 301.

[0036] A cleaning component 400 is disposed between the first sliding block 302 and the second sliding block 303, and the cleaning component 400 is used to clean the recognition display screen 101.

[0037] The aforementioned face recognition device adjusts the height of the recognition display screen 101 by adjusting the height of the lifting plate 202 relative to the slide 201, thereby adapting to the height of different users. At the same time, the first sliding block 302 and the second sliding block 303 slide on the guide slot frame 301 to clean the dust on the screen of the recognition display screen 101, thereby ensuring the recognition effect and improving the recognition efficiency.

[0038] In one embodiment, the adjusting lifting assembly 200 further includes an arc-shaped portion 206 located on the side of the support frame 100. The arc-shaped portion 206 has an arc-shaped groove 203 that communicates with the sliding groove 201. A rotating gear 204 is rotatably connected within the arc-shaped groove 203, and the lifting plate 202 has a rack portion that meshes with the rotating gear 204 for transmission. Specifically, the arc-shaped portion 206 and the support frame 100 are integrally formed. Thus, by rotating the rotating gear 204, the meshing transmission between the rotating gear 204 and the rack portion of the lifting plate 202 causes the identification display screen 101 on the lifting plate 202 to move relatively up and down.

[0039] In one embodiment, the adjusting lifting assembly 200 further includes a drive handwheel 205 at the side end of the arc-shaped portion 206, one end of which is connected to the hub of the rotating gear 204. Thus, rotating the drive handwheel 205 causes the rotating gear 204 to rotate, making operation convenient and reliable.

[0040] In one embodiment, the mobile cleaning assembly 300 further includes a transmission screw 305 and a guide seat 304 respectively disposed on the guide slot frame 301; the first sliding block 302 is tractively connected to the transmission screw 305, and the second sliding block 303 is slidably connected to the guide seat 304. Specifically, the transmission screw 305 is rotatably connected to the guide slot frame 301 via a bearing seat, and the first sliding block 302 is provided with a transmission thread portion adapted to the transmission screw 305. Thus, by rotating the transmission screw 305, the transmission screw 305 and the transmission thread portion of the first sliding block 302 rotate relative to each other, thereby driving the first sliding block 302 to move up and down; at the same time, the guiding effect of the guide seat 304 prevents the second sliding block 303 from deviating during the sliding process.

[0041] In one embodiment, the mobile cleaning assembly 300 further includes a drive motor 103 mounted on the guide rail 301, the output end of which is connected to the hub of the lead screw 305. Thus, the drive motor 103 drives the lead screw 305 to rotate, achieving an automated cleaning function.

[0042] In one embodiment, the cleaning component 400 further includes a cleaning unit disposed between the first sliding block 302 and the second sliding block 303.

[0043] like Figure 3 and Figure 4As shown, in one embodiment, the cleaning unit includes a cleaning block 401 with a groove 403, a movable plate 404 slidably disposed in the groove 403, and a cleaning brush 405 disposed on the movable plate 404; the cleaning brush 405 is disposed outside the groove 403 and is used to contact the identification display screen 101.

[0044] In one embodiment, the cleaning unit further includes a spring-loaded member 402 disposed within the groove 403. One end of the spring-loaded member 402 presses against the inner wall of the groove 403, and the other end presses against the movable plate 404. Specifically, the spring-loaded member 402 is a spring. Thus, by using the spring-loaded member 402 to press against the inner wall of the groove 403, the movable plate 404 is brought closer to the recognition display screen 101, and elastic support is provided during the sliding contact between the cleaning brush 405 and the recognition display screen 101, preventing the cleaning brush 405 from making hard contact with the recognition display screen 101 and causing damage to the recognition display screen 101.

[0045] In one embodiment, the recognition display screen 101 is equipped with a detection camera 102. Thus, the detection camera 102 facilitates facial analysis.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
