In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0051] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0052] Real person verification: An identity verification method that requires users to perform real-time face verification to confirm their true identity. During the real person verification process, users are usually asked to perform facial recognition in front of a camera to ensure that the identity information provided matches the real face. This method can prevent the use of imposter or forged identity information to carry out fraudulent or illegal activities. Real person verification is often used in scenarios such as online account registration, financial transactions, and identity authentication, and can improve the accuracy and security of identity verification.

[0053] Facial recognition (Face Recognition): A biometric technology that identifies or verifies a person's identity by analyzing and recognizing features and patterns on the face. This technology uses computer vision and pattern recognition algorithms to extract facial features such as eyes, nose, mouth, etc. from photos, videos or live cameras, and then compares these features with pre-stored face templates to determine whether there is a match. Facial recognition is commonly used in security systems, face unlocking, identity verification and other fields.

[0054] Camera: A device used to capture images and record videos. It usually consists of components such as a camera, lens, sensor, and image processor. The camera converts light into electrical signals through a photosensitive element (sensor), which is processed by an image processor to ultimately generate a visual image or video.

[0055] See also Figure 1-5 , an embodiment of a facial recognition device with a protective plate provided in the present application comprises: a protective plate 2 and an instrument body 1 equipped with a camera 5;

[0056] At least two plug-in ports 205 are formed on the side wall of the protection plate 2, and the front and rear sides of each plug-in port 205 are formed with an assembly port 206;

[0057] The instrument body 1 is provided with a plug-in block 101 plugged into the plug-in port 205, and each plug-in block 101 is internally slidably connected with two assembly blocks 4 arranged front and back;

[0058] The protection plate 2 is disposed on the upper surface of the instrument body 1 , and the protection plate 2 and the instrument body 1 are detachably connected through the cooperation of the assembly opening 206 and the assembly block 4 .

[0059] It can be understood that the camera 5 is electrically connected to the upper surface of the instrument body 1, and the protective plate 2 is used to protect the instrument body 1, thereby preventing the camera 5 from being damaged; wherein, the number of plug-in blocks 101 can be set according to actual applications, and the specifications of the plug-in blocks 101 and the plug-in interfaces 205 are set correspondingly; if the number of plug-in interfaces 205 is two, the two plug-in interfaces 205 can be respectively set at the middle position of the left and right side walls of the protective plate 2.

[0060] In actual operation, the plug-in block 101 on the instrument body 1 is inserted into the plug-in interface 205 of the protective plate 2, and then the assembly block 4 in the plug-in block 101 is slid so that the assembly block 4 is inserted into the assembly port 206, and the assembly limit of the protective plate 2 is realized by the assembly block 4, thereby completing the assembly of the protective plate 2 on the instrument body 1; correspondingly, when the protective plate 2 needs to be removed, the assembly block 4 is slid so that the assembly block 4 is moved out from the assembly port 206, and the protective plate 2 can be directly removed from the instrument body 1 at this time.

[0061] In the utility model, the protective plate 2 and the instrument body 1 are detachably connected through the cooperation of the assembly port 206 and the assembly block 4, so that the protective plate 2 can be quickly assembled and disassembled. When the instrument body 1 fails or needs to be repaired, the protective plate 2 can be quickly disassembled to facilitate the operator to inspect the instrument body 1.

[0062] In a preferred embodiment, see Figure 3 The front and rear sides of the plug-in block 101 are both provided with square openings 102 , and the inner end faces of the square openings 102 are both provided with movable openings 103 ; the side wall of the plug-in block 101 is provided with two sliding openings 104 ; each sliding opening 104 is connected with the adjacent movable opening 103 to form a strip opening 105 .

[0063] It should be noted that in order to achieve stable assembly, the plug-in block 101 has two square openings 102 that cooperate with the two assembly blocks 4, and the sliding area of ​​the assembly block 4 in the plug-in block 101 is the internal area of ​​the square openings 102; wherein, the diameter of the movable opening 103 is larger than the diameter of the square openings 102.

[0064] In a preferred embodiment, see Figure 2 and Figure 4 A baffle 401 is fixedly installed at the end of the assembly block 4 close to the movable opening 103 to limit the sliding range of the assembly block 4; a positioning spring 404 is fixedly connected to the end of the baffle 401 away from the assembly block 4, and one end of the positioning spring 404 is fixedly connected to the inner side surface of the movable opening 103.

[0065] It can be understood that the baffle 401 is slidably arranged at the movable opening 103, and the movable opening 103 is used to limit the movable area of ​​the baffle 401, thereby limiting the sliding area of ​​the assembly block 4; the positioning spring 404 provides an automatic reset function for the assembly block 4. When the plug-in block 101 is plugged into the plug-in interface 205, the positioning spring 404 will provide elastic force for the assembly block 4, so that the assembly block 4 slides into the assembly opening 206. At the same time, the positioning spring 404 will also apply a continuous elastic force to the assembly block 4, so that the contact between the assembly block 4 and the assembly opening 206 is closer, so as to improve the assembly stability of the protective plate 2 and the instrument body 1.

[0066] In a preferred embodiment, the side wall of the baffle 401 is provided with a slider 402 passing through the strip-shaped opening 105 ; the end of the slider 402 is provided with a square bar 403 , which is slidably arranged at the sliding opening 104 to adjust the sliding position of the assembly block 4 .

[0067] It can be understood that the square bar 403 is pulled at the sliding opening 104 to drive the slider 402 to slide in the strip opening 105, thereby controlling the sliding position of the assembly block 4 to achieve the cooperation between the assembly block 4 and the assembly opening 206 to complete the loading and unloading of the instrument body 1 and the protective plate 2.

[0068] When assembling the protective plate 2, first pull the square bar 403 to slide in the direction of the positioning spring 404, and then drive the assembly block 4 to move inside the square opening 102, until the assembly block 4 is completely moved to the inner area of ​​the square opening 102, at which time the assembly block 4 will compress the positioning spring 404; then plug the protective plate 2 into the instrument body 1, and finally release the control of the square bar 403, the positioning spring 404 will push the baffle 401 to reset, and then drive the assembly block 4 to insert into the inner area of ​​the assembly opening 206, so as to complete the assembly of the protective plate 2 on the instrument body 1. Correspondingly, when disassembling the protective plate 2, it is only necessary to pull the square bar 403 to slide in the direction of the positioning spring 404, and then drive the assembly block 4 to move inside the square opening 102, until the assembly block 4 is completely moved to the inner area of ​​the square opening 102, at which time the assembly block 4 will no longer limit the assembly of the protective plate 2, and the disassembly of the protective plate 2 is completed, and finally the protective plate 2 can be directly removed from the instrument body 1.

[0069] After long-term use, the existing facial recognition device is prone to retain a lot of dirt on the surface of the camera 5. When the facial recognition device performs facial recognition, the dirt on the camera 5 will make it difficult for the facial recognition device to perform facial recognition accurately. Based on this, the utility model is designed with a wiping strip 3 on the protective plate 2 to clean the camera 5.

[0070] In a preferred embodiment, see Figure 1 , Figure 5 and Figure 6An operating port 202 is provided in the middle of the protective plate 2, and a wiping strip 3 is slidably connected to the operating port 202; a cleaning block 301 in contact with the upper surface of the instrument body 1 is detachably connected to the lower surface of the wiping strip 3 for cleaning the camera 5.

[0071] The camera 5 is arranged in the middle of the instrument body 1 , and the setting position of the operation port 202 should correspond to the position of the camera 5 , and should not block the camera 5 to prevent affecting the normal recognition work of the camera 5 .

[0072] It should be noted that the wiping strip 3 and the cleaning block 301 are detachably connected to facilitate replacement of the cleaning block 301; the cleaning block 301 is driven by the wiping strip 3 to wipe the camera 5, thereby achieving standardized wiping and reducing the risk of damage or displacement of the camera 5 caused by manual direct use of the cleaning block 301 to wipe the camera 5.

[0073] In a preferred embodiment, in order to facilitate the movement of the wiping strip 3, please refer to Figure 5 and Figure 6 The lower surface of the protective plate 2 is provided with a movable square opening 201 connected to the operation opening 202 ; both ends of the wiping strip 3 are inserted into the movable square opening 201 .

[0074] It is understandable that when the camera 5 needs to be wiped, the operator controls the wiping block to move back and forth at the moving square opening 201, and the wiping block then drives the cleaning block 301 to move back and forth, so as to wipe the surface of the camera 5, thereby avoiding the presence of dirt on the surface of the camera 5, and the facial recognition device cannot accurately perform facial recognition.

[0075] In a preferred embodiment, see Figure 6 Two limiting rods 303 are symmetrically arranged on the rear side wall of the wiping strip 3; a circular plate 305 is arranged at one end of the limiting rod 303; two limiting holes 204 are arranged on the rear side surface of the movable square opening 201 to allow the limiting rods 303 to pass through; an adjustment hole 203 is arranged on the inner end surface of the limiting hole 204 to allow the circular plate 305 to slide.

[0076] It is understandable that the combination of the limiting rod 303 , the circular plate 305 , the limiting hole 204 and the adjusting hole 203 can control the movement range of the wiping strip 3 , thereby limiting the wiping area of ​​the cleaning block 301 .

[0077] In a preferred embodiment, a return spring 304 is sleeved around the limiting rod 303 ; one end of the return spring 304 is connected to the front end surface of the circular plate 305 , and the other end of the return spring 304 is connected to the front end surface of the adjustment hole 203 .

[0078] Specifically, when the wiping block moves at the movable square opening 201, the wiping block will drive the limiting rod 303 to slide at the limiting hole 204, and the limiting rod 303 will then drive the circular plate 305 to slide at the adjusting hole 203, and the circular plate 305 will compress the reset spring 304. After the operator releases the wiping strip 3, the reset spring 304 will push the circular plate 305 to reset and slide in the adjusting hole 203, and drive the wiping block to move back to the rear side of the movable square opening 201 through the limiting rod 303.

[0079] It can be understood that when the camera 5 is working normally, the reset spring 304 can ensure that the wiping strip 3 is located on the rear side of the movable square opening 201, and prevent the wiping strip 3 from moving to affect the normal shooting of the camera 5; when there is dirt on the camera 5, the operator moves the wiping strip 3 from the rear side of the movable square opening 201 to the front side of the movable square opening 201, and the circular plate 305 will compress the reset spring 304. At this time, the operator can release the wiping strip 3, and the reset spring 304 will push the circular plate 305 to reset and slide in the adjustment hole 203, and then drive the wiping strip 3 to move back to the rear side of the movable square opening 201 through the limit rod 303.

[0080] In a preferred embodiment, see Figure 1 In order to facilitate the operator to control the wiping strip 3, two symmetrically arranged notches 302 are provided on the top of the wiping strip 3.

[0081] In a preferred embodiment, the diameter of the circular plate 305 is greater than the diameter of the limiting hole 204 .

[0082] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
