[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0025] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please see the appendix Figure 1 - Appendix Figure 7This utility model discloses a face recognition device that provides shading. It includes a main body 1 with a light-shielding component 2 carefully positioned on the front. The light-shielding component 2 contains two sets of light-shielding plates 21. A first locking block 22 is securely mounted on the back of the light-shielding plate 21 and movably connected to a first locking slot 2201 on the front of the main body 1. This design allows the light-shielding plate 21 to be precisely positioned above the lens 4, easily blocking excess light interference. Two sets of positioning blocks 24 are installed on the front of the first locking slot 2201. Inside the movable groove of the positioning block 24, one end of a first spring 25 is connected to the bottom surface of the movable groove, and the other end is connected to the bottom surface of a fixed block 26. The fixing block 26 fits perfectly into the fixing groove of the light shield 21, and together with the pull rod 27 that passes through the positioning block 24, a flexible locking system is formed. During daily use, the light shield 21 is firmly fixed; when it needs to be retracted, the pull rod 27 is pulled to compress the first spring 25, and the first locking block 22 disengages from the first locking slot 2201, so the light shield 21 can be quickly removed. Moreover, the second locking slots 2301 on both sides of the identifier body 1 are perfectly matched with the second locking block 23 on the bottom surface of the light shield 21. After the light shield 21 is removed, it can be easily installed on both sides of the identifier body 1, which greatly reduces the space occupied when idle and avoids the loss of parts.

[0027] In Embodiment 1, a groove is provided on the inner side of the right light shield 21, and an embedded block is installed on the inner side of the left light shield 21. The embedded block is adapted to the groove. An installation assembly 3 is provided on the back of the identifier body 1. The installation assembly 3 includes an installation plate 31, an installation block 32, a second spring 33, a locking block 34, a button 35, and a fixing bracket 36. The installation plate 31 is installed on the back of the identifier body 1. Two sets of slots are provided on the surface of the installation plate 31. Two sets of installation blocks 32 are provided. The installation blocks 32 are adapted to the slots. A placement groove is provided on one side of the installation block 32. One end of the second spring 33 is installed on the bottom surface of the placement groove. The other end of the second spring 33 is fixedly connected to the bottom surface of the locking block 34. A through hole is provided on the inner wall of the slot, and the through hole passes through one side of the installation plate 31. The locking block 34 is adapted to the through hole. The button 35 is installed in the through hole. The fixing bracket 36 is fixedly connected to the back of the two sets of installation blocks 32.

[0028] Specifically, the groove on the inner side of the right light shield 21 is precisely matched with the embedded block of the left light shield 21, further ensuring the light shielding effect, preventing light leakage after splicing, and improving the accuracy of face recognition. In the installation component 3, the mounting plate 31 is tightly attached to the main body 1 of the recognizer, and its two sets of slots are matched with the mounting block 32. One side of the mounting block 32 is placed in the slot, and the second spring 33 presses the locking block 34. The locking block 34 is matched with the through hole in the inner wall of the slot, and the button 35 is embedded in the through hole for easy operation. The fixing bracket 36 is connected to the mounting block 32. During installation, the mounting block 32 is inserted into the slot, and the second spring 33 helps the locking block 34 to lock into the through hole, and the device is instantly and stably mounted on the wall or shelf without complicated tools. During disassembly, the button 35 is pressed, and the locking block 34 retracts, making it easy to disassemble, making installation and disassembly quick and effortless.

[0029] In embodiment 2, limit slots are provided on both sides of the inner wall of the placement groove, and limit blocks are installed on both sides of the outer wall of the locking block 34. The limit blocks are movably installed in the limit slots. A lens 4 is provided on the front of the main body 1 of the identifier, an indicator light is provided below the lens 4, a speaker is provided on the surface of the indicator light, and an interface is provided on one side of the main body 1 of the identifier.

[0030] Specifically, limiting grooves are opened on both sides of the inner wall of the placement slot, and correspondingly, the two sides of the outer wall of the locking block 34 are equipped with flexible limiting blocks. The two are precisely matched, making the displacement of the locking block 34 more stable and reinforcing the overall installation structure. On the front of the main body 1 of the identifier, the lens 4 is responsible for accurate capture, the indicator light below intuitively reflects the status, and the speaker next to it can also give timely sound prompts. The interface opened on one side also provides convenience for expanding the function of the device and connecting external devices.

[0031] Working principle:

[0032] First, when blocking light, the two sets of light-blocking plates 21 are movably connected to the first slot 2201 on the front of the identifier body 1 via the first locking block 22 on their backs, and positioned above the lens 4. Under the action of the first spring 25, the fixing block 26 is inserted into the fixing slot of the light-blocking plate 21, so that the light-blocking plate 21 is firmly in place and blocks excess light. If light blocking is not needed, pull the lever 27 to compress the first spring 25, causing the first locking block 22 to disengage from the slot, and remove the light-blocking plate 21. Then, insert the second locking block 23 on the bottom of the light-blocking plate 21 into the second slots 2301 on both sides of the identifier body 1 to complete the storage. The embedding blocks and grooves of the left and right light-blocking plates 21 are precisely aligned. The mounting plate 31 is attached to the back of the main body 1 of the identifier. The mounting block 32 is inserted into the slot of the mounting plate 31. The second spring 33 in the slot of the mounting block 32 pushes the locking block 34 into the through hole of the slot. The device is then securely mounted on the wall or mounting rod by the fixing bracket 36. When disassembling, press the button 35 to retract the locking block 34 and pull out the mounting block 32. At this time, the lens 4 on the front of the main body 1 of the identifier captures the face image for recognition. The indicator light below provides intuitive feedback according to the recognition result. The speaker on the side provides sound prompts as needed. The side interface is used to expand the functions. The entire workflow is now complete.
