[0002] Face recognition is a biometric identification technology that identifies a person's identity based on the person's facial feature information. Face recognition uses a camera or webcam to collect images or video streams containing human faces, and automatically detects and tracks human faces in the images. Technically, it includes image acquisition, feature positioning, identity confirmation and search, etc. However, common face recognition devices are all fixed, and it is not convenient to adjust the tilting angle according to the needs of the operator, resulting in taller operators having to bend down to perform face recognition, which is not only laborious but also inconvenient for users.

[0003] For example, the existing Chinese publication number is: CN214475207U, a face recognition intelligent access control integrated machine, which: "comprises a machine body, a face recognition device is arranged on the front surface of the machine body, digital buttons are arranged on the front surface of the machine body, a display screen is fixedly connected to the front surface of the machine body, a card reader is fixedly connected to the front surface of the machine body, a protective cover is fixedly connected to the front surface of the machine body, a front and rear through empty groove is opened inside the protective cover, an up and down through moving groove is opened inside the protective cover, and a baffle is movably inserted inside the moving groove."

Detailed implementation manners

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0024] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the figure shown by the present utility model, and are hereby explained together.

[0025] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0026] As Figures 1 to 4 shown, a face recognition machine convenient for adjusting the angle includes the main body 1 of the face recognition machine. A U-shaped bracket 2 is provided on the outer periphery of the main body 1 of the face recognition machine. A support leg 15 for supporting the main body 1 of the face recognition machine is welded to the bottom surface of the bracket 2. A plurality of bolts for installing the support leg 15 are threadedly connected to the top surface of the support leg 15, and the main body 1 of the face recognition machine can be installed in the required area.

[0027] The inner cavity of the bracket 2 is provided with an empty groove 4. Both side surfaces of the face recognition machine body 1 are respectively rotatably connected by a pin shaft with a rotating shaft 3 for adjusting the angle. One of the rotating shafts 3 is also rotatably connected to the inner side wall of the bracket 2 by a pin shaft. The free end of the other rotating shaft 3 penetrates into the inner cavity of the empty groove 4 and is connected with a gear 5. The inner bottom surface of the empty groove 4 is provided with a rack 6 meshing with the gear 5. Both side surfaces of the rack 6 are connected with springs 7. The free ends of the two springs 7 are respectively connected with the two inner side walls of the empty groove 4. By moving the rack 6, the rack 6 can drive the meshing gear 5 to rotate, and squeeze and stretch the two springs 7, so that the two springs 7 are deformed under pressure to buffer the pressure received, so as to achieve the damping effect. When the gear 5 rotates, it will drive the face recognition machine body 1 to rotate through the rotating shaft 3, so as to adjust the angle of the face recognition machine body 1, which is convenient for face recognition at different angles. After the recognition is completed, release the rack 6, and the rack 6 can be reset by the rebound of the spring 7. When the rack 6 is reset, it will drive the gear 5 to rotate in the opposite direction, so that the face recognition machine body 1 can be reset to the initial state, which is convenient for subsequent users to adjust the angle, reducing the situation that users need to bend down due to their relatively high height. It is not only labor-saving, but also brings convenience to the use of the face recognition machine.

[0028] Both side surfaces of the rack 6 are welded with connecting blocks 8. One side surface of each of the two connecting blocks 8 is welded with a vertical rod 9. The free ends of the two vertical rods 9 penetrate to one side of the bracket 2. One ends of the two vertical rods 9 located on one side of the bracket 2 are connected with a pulling handle 10. By pulling the pulling handle 10 by personnel, the pulling handle 10 can drive the two vertical rods 9 to move, so that the two vertical rods 9 can drive the rack 6 to move through the connecting blocks 8, so that the user can realize the angle adjustment of the face recognition machine body 1 only by pulling or pushing the pulling handle 10.

[0029] Both side surfaces of the face recognition machine body 1 and both inner side walls of the bracket 2 are provided with a limiting component for limiting the angle adjustment of the face recognition machine body 1. The limiting component includes two limiting grooves 11 and two limiting blocks 12. The two limiting grooves 11 are respectively opened on both inner side walls of the bracket 2. The two limiting blocks 12 are respectively installed on both side surfaces of the face recognition machine body 1. The two limiting blocks 12 are respectively slidably matched with the two limiting grooves 11, and the two limiting grooves 11 and the two limiting blocks 12 are both arranged in a circular array. When the face recognition machine body 1 rotates, it will drive the limiting blocks 12 to rotate in the inner cavity of the limiting grooves 11, so that the limiting grooves 11 and the limiting blocks 12 can assist the face recognition machine body 1 to rotate and improve the stability.

[0030] The inner bottom surface of the empty groove 4 is horizontally provided with a transverse groove 13 for limiting the position of the rack 6. The bottom surface of the rack 6 is connected with a sliding block 14 slidably matched with the transverse groove 13.

[0031] Working principle:

[0032] For this face recognition machine with adjustable angle, when the user needs face recognition, pull the pull handle 10. Let the pull handle 10 drive the rack 6 to move horizontally through the vertical rod 9 and the connecting block 8, and let the rack 6 compress the spring 7. When the rack 6 moves, it will drive the meshing gear 5 to rotate. Thus, the rotating gear 5 drives the angle of the face recognition machine body 1 to be adjusted through the rotating shaft 3, so that the face recognition machine body 1 performs face recognition at a suitable angle. After the recognition, release the pull handle 10, and the rack 6 can return to its original position by the rebound of the spring 7. When the rack 6 returns to its original position, it will drive the gear 5 to rotate in the opposite direction, and then the face recognition machine body 1 can return to the initial state, which is convenient for subsequent users to adjust the angle, reduces the situation that users need to bend down due to their relatively high height, not only saves effort, but also brings convenience to the use of the face recognition machine.
