Description

Technical Field

[0001] The utility model relates to the technical field of integrated access control machines, and in particular to an integrated access control machine for face recognition. Background Art

[0002] The face recognition access control integrated machine is an intelligent security device that combines face recognition technology and access control system for managing and controlling entry and exit. It usually includes a camera, a face recognition algorithm, an access control controller and related software. Its working principle is to capture the user's facial image through a camera, and then use the face recognition algorithm to process and compare the image, identify the user's identity, and ultimately control the opening or closing of the access control device.

[0003] Some existing all-in-one machines are usually placed in an external environment. When adjusting the height of the display screen, a screw rod is usually used to adjust the height of the display screen. At this time, the screw rod is exposed to the outside, and other substances are easily attached to the surface of the screw rod, so that the screw rod cannot normally drive the slider to move up and down. In addition, for such all-in-one machines, rainwater can easily damage the display screen during rain, reducing the service life of the display screen.

[0004] Therefore, those skilled in the art provide a facial recognition access control integrated machine to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a face recognition access control integrated machine is proposed. A first shielding plate and a second shielding plate are arranged to shield the first screw rod to prevent other substances from adhering to the surface of the first screw rod, thereby ensuring the normal operation of the first screw rod. By arranging a shielding mechanism, the display screen can be shielded by a waterproof cloth when it rains, thereby preventing damage to the display screen and increasing its service life.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a face recognition access control integrated machine, comprising a base, a fixed block, a lifting mechanism, a shielding mechanism and a first motor, the lifting mechanism comprising a support plate, a slider, two sliding grooves, two slide plates, two first shielding plates, two second shielding plates and a first screw rod, two arc blocks are fixedly arranged on the lower side of the rear end surface of the slider, a frame plate is fixedly arranged on the front end surface of the slider, a display screen is fixedly arranged between the inner walls on both sides of the frame plate, a camera is embedded on the upper side of the front end surface of the frame plate, and three return springs are fixedly arranged between the two slide plates and the two sliding grooves;

[0007] The shielding mechanism includes a first fixed plate, a second motor, a second screw rod, a waterproof cloth and a second fixed plate. A brush plate is slidably arranged on the upper side near the rear side between the inner walls on both sides of the first fixed plate, and a plurality of bristles are fixedly arranged on the rear end surface of the brush plate.

[0008] Through the above technical scheme, the slider is driven to move downward by the first screw rod, and during the downward movement of the slider, the arc block on the rear side of the slider squeezes the second baffle plate, thereby driving the slider to slide in the inner wall of the sliding groove. At this time, a piece of the first baffle plate on the front side is driven to move by the slider, so that the first baffle plate on the front side does not block the slider. At this time, the slider can move up and down in the inner wall of the support plate under the action of the first screw rod, and the second screw rod is driven to rotate by the second motor. The second screw rod drives the brush plate to move downward, and during the movement of the brush plate, the surface of the camera and the display screen is wiped by the bristles on the surface of the brush plate, and the brush plate drives the waterproof cloth to move, thereby blocking the display screen.

[0009] Furthermore, the lower end surface of the fixing block is fixedly arranged at the middle position of the upper end surface of the base, the support plate is fixedly connected to the base, the first fixing plate is fixedly connected to the support plate, and the second fixing plate is fixedly connected to the first fixing plate;

[0010] Through the above technical solution, the support plate is supported by the base, so that the display screen can be hung in the air, which is convenient for facial recognition.

[0011] Furthermore, the lower end surface of the first motor is fixedly arranged at the middle position of the inner bottom surface of the fixed block, the first screw rod is rotatably arranged between the inner top surface and the inner bottom surface of the lifting plate, the output end of the first motor is fixedly connected to the first screw rod, and the middle inner wall of the slider is threadedly sleeved on the upper side of the outer end surface of the first screw rod;

[0012] Through the above technical solution, the first motor drives the first screw rod to rotate, and during the rotation process, the first screw rod drives the slider to move up and down.

[0013] Furthermore, the two sliding grooves are respectively provided on the end surfaces of both sides of the support plate, the two slide plates are respectively slidably sleeved on the inner walls of the two sliding grooves on opposite sides, and the two first shielding plates and the two second shielding plates are respectively fixedly connected to the two slide plates;

[0014] Through the above technical solution, when the slider moves downward, the arc-shaped block on the surface of the slider is used to resist the second shielding plate on the rear side, thereby driving the slide plate to slide in the sliding groove.

[0015] Furthermore, the second screw is rotatably arranged on one side of the upper end surface of the first fixed plate, the second motor is fixedly connected to the first fixed plate, the output end of the second motor is fixedly connected to the second screw, and the middle position of the inner wall of one side of the brush plate is threadedly sleeved on the upper side of the outer end surface of the second screw;

[0016] Through the above technical solution, the second motor drives the second screw rod to rotate, and during the rotation process, the second screw rod drives the brush plate to move up and down.

[0017] Furthermore, one end of the waterproof cloth is fixedly connected to the brush plate, and the other end of the waterproof cloth is connected to the second fixing plate through an elastic rope;

[0018] Through the above technical solution, when the brush plate moves upward, the waterproof cloth is driven to move upward by the resilience of the elastic rope, so that the waterproof cloth can be restored to its original position.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model proposes a facial recognition access control integrated machine, in which a first motor drives a first screw rod to rotate, and the first screw rod drives a slider to move downward during the rotation. During the movement of the slider, the arc block on the rear side abuts against the second shielding plate, thereby driving the slider to slide in the sliding groove. At this time, the first shielding plate on the front side does not shield the front end of the first screw rod. The first shielding plate and the second shielding plate are set to shield the first screw rod, so as to prevent other substances from adhering to the surface of the first screw rod, thereby ensuring the normal operation of the first screw rod.

[0021] 2. The utility model proposes a facial recognition access control integrated machine, in which the second motor drives the second screw rod to rotate, and the second screw rod drives the brush plate to move downward. During the movement of the brush plate, the bristles on the surface of the brush plate wipe the surface of the camera and the display screen. During the movement of the brush plate, the waterproof cloth is driven to move downward, thereby shielding the front side of the display screen. By setting a shielding mechanism, the display screen can be shielded by the waterproof cloth when it rains, thereby avoiding damage to the display screen and increasing its service life.
