All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a face recognition identity authentication device, including a face recognition instrument 10, a housing 20 is arranged outside the face recognition instrument 10, a fixing plate 30 is arranged on the housing 20, a mounting plate 31 is arranged on the back of the face recognition instrument 10, a top plate 3001 is arranged on one side of the fixing plate 30, a motor 3003 is arranged on the back of one side of the top plate 3001, a lead screw 3004 is arranged on the output shaft of the motor 3003, two movable blocks 3005 are arranged outside the lead screw 3004, a power supply module 3011 is arranged on the fixing plate 30, a supplementary light 3007 is arranged on the front of one side of the fixing plate 30, a controller 3008 is arranged on the front of one side of the top plate 3001, a photosensitive sensor 3009 is arranged on the front of one side of the top plate 3001, the power supply module 3011 is electrically connected to the controller 3008, the controller 3008 is respectively electrically connected to the supplementary light 3007 and the photosensitive sensor 3009, a signal transmission end of the photosensitive sensor 3009 sends a signal to a signal receiving end of the controller 3008, two fixing brackets 3102 are arranged on one side of the mounting plate 31, and hinge rods 3103 are hinged between the two fixing brackets 3102 and the two movable blocks 3005.

[0025] Among them, a fixing block 3006 is arranged at the center of one side of the fixing plate 30, a fixing hole is opened on one side of the fixing block 3006, the model of the photosensitive sensor 3009 is one of STK3331-A, OLGA-8, GL5516, MJ4537, ZXM363348. When the light is too strong, the photosensitive sensor 3009 converts the optical signal into an electrical signal and transmits it to the controller 3008. The controller 3008 controls the motor 3003 to start, and drives the lead screw 3004 to rotate to make the two movable blocks 3005 move towards the opposite side. The face recognition instrument 10 is driven to move backward into the interior of the housing 20 through the hinge rod 3103, and part of the light is blocked by the housing 20 to avoid exposure. When the light is insufficient, the photosensitive sensor 3009 converts the optical signal into an electrical signal and transmits it to the controller 3008. The controller 3008 controls the supplementary light 3007, and the supplementary light 3007 supplements the light to improve the recognition success rate of the face recognition instrument 10.

[0026] At the same time, the supplementary light 3007 is located between the controller 3008 and the photosensitive sensor 3009, and the fixing plate 30 is designed in a "T" shape.

[0027] In addition, the thread directions at the upper and lower ends of the outer surface of the lead screw 3004 are opposite. A threaded hole is provided on one side of the movable block 3005. The lead screw 3004 passes through the threaded hole and is threadedly connected to the threaded hole. When the motor 3003 is started, the lead screw 3004 rotates to drive the two movable blocks 3005 to move towards the opposite side. When the motor 3003 drives the lead screw 3004 to rotate in the reverse direction, the two movable blocks 3005 move towards the opposite sides. At this time, the articulated rod 3103 pushes the face recognition device 10 to reset.

[0028] In addition, the lead screw 3004 passes through the fixing hole. The fixing block 3006 is made of rubber or soft silicone. The fixing block 3006 can prevent the face recognition device 10 from hitting structures such as the motor 3003 and the lead screw 3004 when the face recognition device 10 moves backward into the interior of the housing 20.

[0029] It should be noted that a bottom plate 3002 is provided on the other side of the fixing plate 30. Two limiting grooves 3010 are provided on one side of the bottom plate 3002. Limiting blocks 3101 that cooperate with the limiting grooves 3010 are provided on both sides at one end of the mounting plate 31.

[0030] It can be understood that the two limiting grooves 3010 are symmetrically distributed left and right. The bottom plate 3002 is designed in a "U" shape. The other end of the lead screw 3004 is rotatably connected to the bottom plate 3002.

[0031] Finally, the two limiting blocks 3101 are respectively inserted into the two limiting grooves 3010 and are slidably connected to the limiting grooves 3010. The limiting blocks 3101 are designed in an "L" shape. The cooperation between the limiting blocks 3101 and the limiting grooves 3010 can support and limit the face recognition device 10, improving the stability of the face recognition device 10 during the movement process.

[0032] Specifically, the working principle of this face recognition identity authentication device is as follows:

[0033] When in use, a person stands directly in front of the face recognition device 10. The face can be recognized through the camera on the face recognition device 10. During the use process, when the light is too strong, the photosensitive sensor 3009 converts the optical signal into an electrical signal and transmits it to the controller 3008. The controller 3008 controls the motor 3003 to start and drives the lead screw 3004 to rotate, causing the two movable blocks 3005 to move towards the opposite side. The articulated rod 3103 drives the face recognition device 10 to move backward into the interior of the housing 20, and the housing 20 blocks part of the light to avoid overexposure. When the light is insufficient, the photosensitive sensor 3009 converts the optical signal into an electrical signal and transmits it to the controller 3008. The controller 3008 controls the fill light 3007 to supplement the light and improve the recognition success rate of the face recognition device 10;

[0034] It should be noted that the specific model specifications of the face recognition device 10, the motor 3003, the fill light 3007, the controller 3008, the photosensitive sensor 3009, and the power supply module 3011 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0035] The power supply and its principle of the face recognition device 10, the motor 3003, the fill light 3007, the controller 3008, the photosensitive sensor 3009, and the power supply module 3011 are clear to those skilled in the art and will not be described in detail here.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0037] In addition, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", "third", and "fourth" may explicitly or implicitly include at least one of such features.
