Technical Field

[0001] The utility model relates to the technical field of face recognition equipment, in particular to a face recognition equipment with a lens protection function. Background Art

[0002] A facial recognition device is a hardware device that uses computer vision and pattern recognition technology to identify faces. It has a wide range of applications and relies on photographing and identifying faces to determine the identity of the corresponding person. However, during use, this device will have corresponding problems due to the height of the person. That is, the device cannot fully identify people who are lower than the height of the camera, which will cause abnormal recognition. In addition, when there is sufficient light, the person's face will be backlit, which can easily affect the camera's imaging to a certain extent.

[0003] Therefore, a face recognition device with a lens protection function is now developed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices that cannot fully identify people who are below the height of the camera, thus causing abnormal identification, and that the person's face is backlit when there is sufficient light, which easily affects the camera's imaging to a certain extent, the utility model provides a face recognition device with a lens protection function.

[0006] Furthermore, it also includes an L-shaped plate, the L-shaped plate is connected to the front side of the lower part of the face recognition device, two second guide members that are symmetrical on the left and right are connected inside the L-shaped plate, a first limit member is slidably connected between the second guide members, two second springs are connected between the first limit member and the L-shaped plate, the left and right parts of the first limit member are both slidably connected to the second limit member, the second limit member is connected to the L-shaped plate in a through-type connection, and a third spring is connected between the second limit member and the first limit member.

[0007] Furthermore, it also includes a mounting column, the mounting column is slidably connected to the lower side of the mounting frame, a third limiting member is threadedly connected between the mounting column and the mounting frame, and the third limiting member has a screw handle.

[0008] Furthermore, L-shaped rubber pads are connected to both left and right sides of the installation frame.

[0010] Furthermore, each of the second limiting members is provided with a power assist rod.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] The utility model can take into account the different heights of users during use. For some people who are not tall enough, the lower side of the face recognition device can be pushed to make the first guide member slide, thereby compressing the first spring, and then flipping the face recognition device, so that the face recognition device can recognize the face of the person, thereby improving the flexibility of face recognition. During use, light can be blocked to avoid the influence of strong light on face recognition. At the same time, it has a stronger protection effect and can prevent the equipment from being damaged.

DETAILED DESCRIPTION

[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] A face recognition device with lens protection function, such as Figure 1-Figure 5As shown, it includes a mounting frame 1, L-shaped rubber pads are connected to the left and right sides of the mounting frame 1, a first guide member 21 is slidably connected inside the mounting frame 1, a first spring 22 is connected between the first guide member 21 and the mounting frame 1, a face recognition device 2 is connected to the front end of the first guide member 21, a shielding plate 3 for protecting the camera position of the face recognition device 2 from strong light is rotatably connected to the front side of the upper part of the mounting frame 1, two symmetrical torsion springs 4 are connected between the shielding plate 3 and the mounting frame 1, a protective plate 5 for covering and protecting the face recognition device 2 is rotatably connected to the top of the mounting frame 1, a buckle 6 is connected to the rear side of the protective plate 5, a snap-on plate is connected to the top of the mounting frame 1, the snap-on plate is snap-on with the buckle 6, and the face recognition device 2 An L-shaped plate 7 is connected to the front side of the lower part, and two second guide members 9 are connected to the inside of the L-shaped plate 7 which are symmetrical on the left and right. A first limit member 8 for locking and limiting the protective plate is slidably connected between the second guide members 9, and two second springs 10 are connected between the first limit member 8 and the L-shaped plate 7. The left and right parts of the first limit member 8 are slidably connected to second limit members 11, and the second limit member 11 is through-connected to the L-shaped plate 7. The second limit members 11 are provided with power assist rods, and third springs 12 are connected between the second limit members 11 and the first limit members 8. A mounting column 13 is slidably connected to the lower side of the mounting frame 1, and a third limit member 14 is threadedly connected between the mounting column 13 and the mounting frame 1, and the third limit member 14 is provided with a screwdriver.

[0021] It should be noted that the face recognition device is a hardware device that uses computer vision and pattern recognition technology to recognize faces. It has a wide range of applications, and the present device is mainly suitable for similar directions such as students clocking in or employees clocking in. When in use, the third limit member 14 is rotated according to the commonly used range, so that the mounting column 13 and the mounting frame 1 are no longer in a locked state, and then the mounting frame 1 is pulled upward to achieve the effect of adjusting the height of the face recognizer 2. After the adjustment is completed, it is put into use normally. However, due to the different heights between people, some people's heights are not enough to reach the height position of the camera of the face recognizer 2, which will cause the recognition and authentication to fail. At this time, the corresponding personnel can push the lower side of the face recognizer 2 to make the first guide member 21 slide, so that the first spring 22 is compressed, and then the face recognizer 2 is flipped, so that the face recognizer 2 can recognize the face of the person, and the face recognizer 2 is released after the recognition is completed. Under the action of the first spring 22, the face recognizer 2 will automatically reset.

[0022] It should be noted that during use, in order to prevent strong light from affecting face recognition, the baffle plate 3 is used to block and protect the camera of the face recognition device 2 to improve the efficiency of face recognition. After use, the buckle 6 is disengaged from the clamping piece on the mounting frame 1, and then the protective plate 5 is flipped downward 180 degrees so that the protective plate 5 can completely block the face recognition device 2. In this process, the protective plate 5 will push the baffle plate 3, so that the baffle plate 3 rotates 90 degrees, and then the camera on the face recognition device 2 is blocked and protected. After the blocking is completed, the second limit member 11 is pushed inward, so that the third spring 12 is compressed. At this time, the first limit member 8 is no longer locked. In the initial state, the second spring 10 is in a compressed state. Under the action of the second spring 10, the first limit member 8 will slide upward, thereby locking and limiting the protective plate 5. At the same time, the L-shaped plate 7 will lock and fix the second limit member 11 to prevent the second limit member 11 from resetting.

[0023] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
