Description

Technical Field

[0001] The utility model relates to the field of iris recognition equipment, in particular to an iris recognition device. Background Art

[0002] Iris recognition is a biometric identification technology that uses the human iris as a carrier and means of identification. The iris's highly unique, stable, and unchangeable characteristics are the material basis for its use in identity verification. Existing iris recognition devices generally only recognize the subject at very close range, facing the iris camera.

[0003] According to the iris recognition device disclosed in the existing patent document with publication number CN216014329U, it includes an interactive display module and an acquisition module and a fill light module arranged on both sides of the interactive display module in the horizontal direction. The interactive display module includes a display and a processor. The acquisition module includes an iris camera, a face camera and a ranging sensor. The fill light module includes a near-infrared fill light. The acquisition module and the fill light module are connected to the interactive display module through a horizontal rotation axis. When used, this technical solution automatically tracks the object to be identified without the need for the object to be identified to actively cooperate. It can adapt to longer distances and larger angle ranges and can reduce the angle requirements and distance requirements of the object to be identified. Regarding the above technical solution, although this solution realizes iris recognition, the camera cannot be stored and protected after the recognition is completed, which is inconvenient when used.

[0004] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide an iris recognition device to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. When in use, the support base pushes the mounting base to move upward. After the movable disk is exposed upward, the fill light is turned on by the switch to illuminate the face. In addition, driven by the movable disk, the mounting base moves up and down inside the observation window, and the up and down movement completes the adjustment of the camera height, completing iris recognition for users of different heights. After recognition, it moves to the inside of the cavity for shielding and protection.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solution: an iris recognition device, including a fixing seat, a fixing block welded to one side of the fixing seat, a fixing plate movably installed between the fixing blocks, movable plates movably installed on the sides of the fixing plates, the movable plates movably contact the fixed blocks, an observation window is provided on the fixing seat, a display mechanism is installed on the side of the observation window, a button is installed at the bottom of the display mechanism, a cavity is provided inside the fixing seat, and a movable disk is movably installed inside the cavity.

[0006] Furthermore, a limiting block is welded to one end of the fixed block, a limiting groove is opened on the side of the movable plate, and the limiting groove is movably mounted on the limiting block.

[0007] Furthermore, an arc-shaped groove is formed on the fixing plate, a fixing bolt is movably installed inside the arc-shaped groove, and a limiting plate is welded to one end of the fixing bolt.

[0008] Furthermore, a rotating column is fixed on one side of the fixing seat, a torsion spring is installed on the rotating column, a fixing hole is opened on the fixing plate, and the rotating column is installed inside the fixing hole through the torsion spring.

[0009] Furthermore, a sealing ring is fixed on the inner wall of the cavity, a fill light is fixedly installed on the side of the movable disk, and a connecting rod is fixed on the bottom of the movable disk.

[0010] Furthermore, a mounting seat is fixed to one end of the connecting rod, and a camera is fixedly mounted on the mounting seat.

[0011] Furthermore, a support base is fixed to the bottom of the mounting base, and a switch is installed on the support base.

[0012] Furthermore, a slide groove is opened on the inner wall of the cavity, a slider is movably installed inside the slide groove, a support mechanism is fixed between the slider and the slide groove, and one end of the slider is fixed on the mounting seat.

[0013] Beneficial effects of the utility model:

[0014] 1. This iris recognition device, when in use, pushes the mounting base upward through the support base. After the movable disk is exposed upward, the fill light is turned on by a switch to illuminate the face. In addition, driven by the movable disk, the mounting base moves up and down inside the observation window, and the up and down movement completes the adjustment of the camera height to complete iris recognition for users of different heights. After recognition, it moves into the cavity for shielding and protection.

[0015] 2. In this iris recognition device, the rotation of the fixed plate limits the fixing bolt to be installed inside the arc groove, and the movable plate is installed on the side of the fixed plate to limit the fixed plate, so that the fixed plate limits and fixes the fixing bolt. After the movable plate is removed later, the fixed plate rotates, and the fixed plate and the fixing bolt are separated after rotation, which facilitates the rapid disassembly of the fixing base later.
