[0003] Facial recognition devices are used in different scenarios. In some scenarios where facial recognition devices are used, there are scenes with large flow of people. When facial recognition devices are used in places with dense flow of people, pedestrians may accidentally touch or scratch the device when passing by quickly, especially during peak hours. The flow of people is dense and moves fast, which increases this risk. When the facial recognition device is scratched frequently or with great force, the device's casing, lens or other components may be damaged, thereby reducing the device's recognition accuracy or causing damage, which in turn affects the speed of pedestrians' passage.

[0010] As a preferred embodiment, a slider is fixedly connected to the outer wall of the face recognition machine, a slide groove is provided inside the fixed tube, and the outer wall of the slider fits in the slide groove provided in the fixed tube.

[0011] The beneficial effect of adopting the above further scheme is: by setting a slider and a slide groove, the positioning of the face recognition machine is achieved.

[0020] A method for using a self-protection face recognition device, applied to any of the above-mentioned self-protection face recognition devices, comprises the following steps: S1: When pedestrians pass through the face recognition gate, they may touch the face recognition machine unconsciously. When the face recognition machine is touched, it will cause a twisting force on the rotating block through the fixed tube. At this time, the rotating block drives the linkage block and the connecting block to rotate. The rotation of the connecting block will drive the rotating plate and the ball to rotate on the limit plate, so that the face recognition machine rotates after the force is applied, so as to avoid damage to the face recognition machine after the impact force. At the same time, when the rotating plate and the connecting rod rotate on the limit plate, one side of the rotating plate will not be separated from the side of the limit plate. At this time, the rotation of the rotating plate will cause the two extension rods to have opposite results under the action of the two first springs, one extension rod moves up and the other extension rod moves down. When the pedestrian passes through the face recognition gate, the first spring will apply force to the extension rod to restore the extension rod to its original position. After the extension rod returns to its original position, the connecting block will drive the linkage block and the rotating block to rotate, so that the face recognition machine returns to its original position after rotation, so as to facilitate subsequent face recognition.

[0021] S2: When pedestrians pass through the face recognition gate and touch the face recognition machine unconsciously, they will first squeeze the L-shaped plate. At this time, the L-shaped plate will shrink under the action of the second spring. Under the action of the second spring, the shrinking L-shaped plate will absorb part of the impact force to avoid excessive impact force, thereby avoiding damage to the face recognition machine. At the same time, by using the first soft pad and the second soft pad in coordination with each other, when the L-shaped plate is moving, the first soft pad will first contact the second soft pad to avoid damage to the face recognition machine under the impact of the L-shaped plate, thereby avoiding affecting the passage speed of pedestrians.

[0022] S3: Disengage the handle from the clamping ring, and use the handle to rotate the rotating ring, so that the clamping rod is clamped with the Yiduoli fixed frame. After the clamping rod is disengaged from the fixed frame, the round rod is moved through the clamping rod, so that the round rod drives the plug-in block to move out of the range of the through opening. After the plug-in block is within the range of the through opening, the face recognition machine can be disassembled as a whole, so as to achieve rapid replacement of the face recognition machine, thereby avoiding the face recognition machine being replaced slowly after being damaged, which affects the use of the face recognition gate.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are: 1. When pedestrians pass through the face recognition gate, they may unconsciously touch the face recognition machine. At this time, the face recognition machine will rotate through the rotating block after being touched. The rotation of the rotating block will cause the connecting block and the rotating plate to rotate, thereby causing the ball to rotate on the limit plate. When the rotating plate rotates, it will affect the two extension rods, causing the two extension rods to change under the action of the two first springs. After the pedestrian passes through the face recognition gate, the extension rod will return to its original position under the action of the first spring, thereby causing the face recognition machine to rotate to its original position.

[0024] 2. The quick disassembly of the quick-release structure can be achieved through the mutual cooperation of the fixed tube, the through-port, the fixed frame, the plug-in block, the round rod, the rotating ring and the clamping rod. When the face recognition machine needs to be replaced or is damaged during long-term use, the clamping rod can be used to make the round rod drive the plug-in block to move, so that the plug-in block is out of the range of the through-port, thereby achieving quick disassembly of the face recognition machine, thereby avoiding the face recognition machine affecting the use of the face recognition gate after being damaged.

[0025] 3. Through the cooperation of the connecting ring, the fixing sleeve, the second spring and the L-shaped plate, the face recognition machine can be further protected. When a pedestrian touches the face recognition device while moving, he will touch the L-shaped plate next, so that the second spring can offset the force of the touch in advance, thereby avoiding the face recognition machine from rotating too much, thereby avoiding affecting the speed of the face recognition machine returning to its original position.

[0037] A method for using a self-protection face recognition device, applied to any of the above-mentioned self-protection face recognition devices, comprises the following steps: S1: When pedestrians pass through the face recognition gate 1, they may unconsciously touch the face recognition machine 4. When the face recognition machine 4 is touched, it will cause a twisting force on the rotating block 204 through the fixed tube 301. At this time, the rotating block 204 drives the linkage block 205 and the connecting block 207 to rotate. The rotation of the connecting block 207 will drive the rotating plate 209 and the ball 210 to rotate on the limit plate 211, so that the face recognition machine 4 rotates after being subjected to force, so as to avoid damage to the face recognition machine 4 after being subjected to impact force. At the same time, when the rotating plate 209 and the connecting rod 201 rotate on the limit plate 211, one side of the rotating plate 209 will not Separated from one side of the limit plate 211, the rotation of the rotating plate 209 at this time will cause the two extension rods 208 to have opposite results under the action of the two first springs 206, one extension rod 208 moves up and the other extension rod 208 moves down. When the pedestrian passes through the face recognition gate 1, the first spring 206 will apply force to the extension rod 208 to restore the extension rod 208 to its original position. After the extension rod 208 returns to its original position, the connecting block 207 will drive the linkage block 205 and the rotating block 204 to rotate, so that the face recognition machine 4 returns to its original position after rotation, thereby facilitating subsequent face recognition.

[0038] S2: When a pedestrian passes through the face recognition gate 1 and touches the face recognition machine 4 unconsciously, the L-shaped plate 504 will be squeezed first. At this time, the L-shaped plate 504 will shrink under the action of the second spring 503. Under the action of the second spring 503, the shrinking L-shaped plate 504 will absorb part of the impact force to avoid excessive impact force, thereby avoiding damage to the face recognition machine 4. At the same time, by using the first soft pad 505 and the second soft pad 506 in coordination with each other, when the L-shaped plate 504 is moving, the first soft pad 505 will first contact the second soft pad 506 to avoid damage to the face recognition machine 4 under the impact of the L-shaped plate 504, thereby avoiding affecting the passage speed of pedestrians.

[0039] S3: Disengage the handle 308 from the clamping connection of the clamping ring 309, and rotate the rotating ring 306 through the handle 308, so that the clamping rod 307 can overflow the clamping connection of the fixed frame 303. After the clamping rod 307 is disengaged from the clamping connection of the fixed frame 303, the round rod 305 is moved through the clamping rod 307, so that the round rod 305 drives the plug block 304 to move out of the range of the through opening 302. After the plug block 304 is within the range of the through opening 302, the user can disassemble the face recognition machine 4 as a whole, so as to realize the rapid replacement of the face recognition machine 4, thereby avoiding the face recognition machine 4 being replaced slowly after being damaged, which affects the use of the face recognition gate 1.

[0040] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the self-protection face recognition device and the method of using the same, when a pedestrian passes through the face recognition gate 1, he may unconsciously touch the face recognition machine 4, and the object that touches the face recognition machine 4 will next touch the L-shaped plate 504. After being touched, the L-shaped plate 504 moves inward under the action of the second spring 503, thereby preliminarily reducing the touch force. When the touch force is large, the L-shaped plate 504 contracts inward. The first soft pad 505 will contact the second soft pad 506, thereby protecting the face recognition machine 4. At the same time, when the first soft pad 505 and the second soft pad 506 contact, the face recognition machine 4 will rotate the rotating block 204 after being subjected to the touch force. The rotation of the rotating block 204 will drive the linkage block 205 and the connecting block 207 to rotate, thereby driving the rotating plate 209 to rotate on the limit plate 211 through the ball 210. At this time, the rotation of the rotating plate 209 will affect the extension rod 208, and the extension rod 208 will shrink or expand under the action of the first spring 206. When a pedestrian passes through the face recognition gate 1, the expanded or contracted first spring 206 will affect the extension rod 208, causing the extension rod 208 to push the rotating plate 209, so that the face recognition machine 4 can return to its original position under the action of the rotating plate 209, thereby avoiding affecting the subsequent pedestrian's passage efficiency.

[0041] When the face recognition machine 4 needs to be replaced after being used for a long time, the staff moves the handle 308 to make the handle 308 disengage from the clamping of the clamping ring 309, and then uses the handle 308 to make the fixing rod 307 disengage from the clamping of the fixed frame 303, so that the round rod 305 is driven to move by the fixing rod 307, and the plug block 304 is driven to disengage from the inside of the through hole 302 by the round rod 305, thereby realizing the disassembly of the face recognition machine 4. After the face recognition machine 4 is disassembled, the staff replaces the new face recognition machine 4 and fixes the face recognition machine 4 through the above operations.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.

9. A method for using a self-protection face recognition device, applied to a self-protection face recognition device according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1: When a pedestrian passes through the face recognition gate (1), the pedestrian may unconsciously touch the face recognition machine (4). When the face recognition machine (4) is touched, the fixed tube (301) causes a twisting force to be applied to the rotating block (204). At this time, the rotating block (204) drives the linkage block (205) and the connecting block (207) to rotate. The connecting block (207) drives the rotating plate (209) and the ball (210) to rotate on the limit plate (211), so that the face recognition machine (4) rotates after being subjected to the force, thereby preventing the face recognition machine (4) from being damaged after being subjected to the impact force. At the same time, when the rotating plate (209) and the connecting rod (201) rotate on the limit plate (211), one side of the rotating plate (209) It will not separate from one side of the limit plate (211). At this time, the rotation of the rotating plate (209) will cause the two extension rods (208) to produce opposite results under the action of the two first springs (206), one extension rod (208) moves up, and the other extension rod (208) moves down. When a pedestrian passes through the face recognition gate (1), the first spring (206) will apply a force to the extension rod (208) so that the extension rod (208) returns to its original position. After the extension rod (208) returns to its original position, the connecting block (207) will drive the linkage block (205) and the rotating block (204) to rotate, so that the face recognition machine (4) returns to its original position after the rotation, thereby facilitating subsequent face recognition. S2: When a pedestrian passes through the facial recognition gate (1), when the pedestrian touches the facial recognition machine (4) unconsciously, the L-shaped plate (504) is first squeezed. At this time, the L-shaped plate (504) contracts under the action of the second spring (503). Under the action of the second spring (503), the contracted L-shaped plate (504) absorbs part of the impact force, thereby preventing the impact force from being too large, thereby preventing the facial recognition machine (4) from being damaged. At the same time, by using the first soft pad (505) and the second soft pad (506) to cooperate with each other, when the L-shaped plate (504) moves, the first soft pad (505) will first contact the second soft pad (506), thereby preventing the facial recognition machine (4) from being damaged under the impact of the L-shaped plate (504), thereby avoiding affecting the pedestrian's passing speed; S3: The handle (308) is separated from the clamping connection of the clamping ring (309), and the rotating ring (306) is rotated by the handle (308), so that the clamping rod (307) is clamped to the Yiduoli fixed frame (303). After the clamping rod (307) is separated from the clamping connection of the fixed frame (303), the round rod (305) is moved by the clamping rod (307), so that the round rod (305) drives the plug (304) to move out of the range of the opening (302). After the plug (304) moves out of the range of the opening (302), the user can disassemble the face recognition machine (4) as a whole, so as to achieve rapid replacement of the face recognition machine (4), thereby avoiding the face recognition machine (4) being replaced slowly after being damaged, which affects the use of the face recognition gate (1).
