Two L-shaped guide rods 8 are fixedly connected to the top of the support block.

The guide blocks 9 cooperate with the L-shaped guide rods 8 to play a vertical guiding effect on the vertical rod 5. The front side of the mounting seat 100 is fixedly connected with an infrared sensor 13;

[0028] A first controller 12 is fixed and electrically connected to the right side of the driving motor 7, and an infrared sensor 13 is electrically connected to the first controller 12. The infrared sensor 13 is used to sense whether there is a person, and its sensing principle is a prior art and is not specifically described here. A first touch switch 10 is embedded and fixed on the bottom inner wall of the protective box 1, and the top of the first touch switch 10 is in active contact with the bottom of the face recognition device 105.

[0029] Working principle: The entire device is fixed at a desired position by a support base. When the face recognition device 105 is not in use, the shielding plate 4, the mounting base 100 and the protective box 1 cooperate to provide comprehensive shielding protection, which can effectively reduce the risk of accidental damage when not in use;

[0030] During use, when the infrared sensor 13 senses someone, it transmits a signal to the first controller 12, and the first controller 12 controls the drive motor 7 to turn on in the forward direction. The output shaft of the drive motor 7 drives the screw 6 to rotate. Under the action of the threaded hole on the vertical rod 5, the screw 6 rotates and drives the vertical rod 5 to move upward. The vertical rod 5 drives the face recognition device 105 to move upward. The vertical rod 5 also drives the two guide blocks 9 to slide upward on the corresponding L-shaped guide rods 8. When the guide block 9 on the right moves upward until it contacts the bottom of the second touch switch 11, the face recognition device 105 is completely removed from the first slot 2 and the protective box 1, and the second touch switch 11 is triggered to turn on. A signal to turn off is passed to the first controller 12, and the first controller 12 controls the drive motor 7 to turn off. At this time, the face recognition device 105 can recognize the face of the pedestrian and analyze the recognized face. If it is a person being entered, the information is passed to the second controller, and the second controller controls the brake motor 104 to open in the forward direction. The output shaft of the brake motor 104 drives the rotating block 103 to rotate backward through the rotating shaft, and the rotating block 103 drives the access control baffle 102 to rotate backward to release the access control. When a person passes by, the brake motor 104 starts in the reverse direction, and the access control baffle 102 is driven to rotate forward and reset to continue to block. The specific principle of driving the access control baffle 102 is the existing technology and is not specifically explained here.

[0031] During the face recognition process, the shielding plate 4 is always on the top of the face recognition device 105 to block. When an object falls from a high place, the impact force of the falling object drives the shielding plate 4 to move downward, and the shielding plate 4 drives the two guide rods 15 to slide downward in the corresponding guide tubes 14 respectively. When the shielding plate 4 moves downward, it compresses the buffer spring 16. The elastic force of the buffer spring 16 can effectively buffer and unload the impact force of the object falling from a high place, thereby achieving the effect of shielding and protecting the face recognition device 105 when in use;

[0032] After the person has passed, when the infrared sensor 13 senses that there is no one, the first controller 12 controls the drive motor 7 to start in reverse, which is the opposite of the movement process of the drive motor 7 starting in the forward direction, so that the face recognition device 105 is transformed to move downward into the protective box 1. When the bottom of the face recognition device 105 contacts the top of the first touch switch 10, the face recognition device 105 is completely moved into the protective box 1, and the first touch switch 10 is triggered to turn on. The first touch switch 10 transmits a closing signal to the first controller 12, and the first controller 12 controls the drive motor 7 to turn off. At this time, the mounting seat 100 and the protective box 1 continue to fully surround and block the face recognition device 105. By automatically storing and protecting the face recognition device 105 when not in use, the risk of the face recognition device 105 being accidentally touched and damaged when not in use can be effectively reduced, thereby achieving effective protection for the face recognition device 105 and improving the safety of the face recognition device 105.

[0033] When the face recognition device 105 is moved upward or stored downward, its front side will rub against the wiping cotton. The friction force can effectively wipe and clean the dust on the front side of the face recognition device 105, thereby improving the clarity of the face recognition device 105.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
