Description

Technical Field

[0001] The utility model relates to the field of face recognition equipment, in particular to a face recognition device with adjustable storage. Background Art

[0002] Face recognition is a biometric technology that identifies people based on their facial features. It uses a camera or camcorder to collect images or video streams containing faces, and automatically detects and tracks faces in images, and then performs a series of face-related technologies on the detected faces. It is usually also called portrait recognition or facial recognition. Face recognition is mainly used for identity recognition.

[0003] The application number is CN202320592941.3, and the patent name is a patent application for a face recognition terminal with adjustable camera angle. A connecting ball is fixedly installed on the back of the face recognition device, and a locking ball sleeve that cooperates with the connecting ball is set on the frame. The connecting ball is configured in the locking ball sleeve. There is a certain friction between the connecting ball and the locking ball sleeve. This structure achieves adjustment by manually rotating the face recognition device, which is very inconvenient.

[0004] The application number is CN202122517874.2, and the patent name is a patent application for an adjustable angle facial recognition device. A worm gear is installed on the back of the device recognition body, and a worm is installed on the front of the frame. The worm gear is meshed with the worm gear, and the angle of the device recognition body is adjusted by manually rotating the worm gear. This structure still requires manual adjustment of the angle, which is still inconvenient. In addition, the worm gear will affect the storage of the entire device recognition body, causing damage when placed. In addition, the adjustment mechanism is located in a visible position, which is not beautiful.

[0005] Therefore, it is urgent to design a face recognition device that can automatically adjust the face recognition device body and can also be stored. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an adjustable and storable face recognition device, which can automatically adjust the recognition angle of the face recognition device body and can also be stored with high aesthetics.

[0007] In order to solve the above technical problems, the technical solution of the present invention is: an adjustable and retractable face recognition device, comprising:

[0008] The identification instrument mounting platform is provided with a sliding groove penetrating in the up-down direction, a sliding block slides in the sliding groove, and the lower end of the sliding block passes through the sliding groove from top to bottom;

[0009] The face recognition device body has a bottom hinged on the recognition device mounting platform, and a fixing block is fixed in the middle or top;

[0010] A linkage rod, one end of which is hinged to the sliding block, and the other end of which is hinged to the fixed block;

[0011] The power mechanism is installed on the back of the recognition device installation platform and is connected to the lower end of the sliding block, and is used to drive the sliding block to slide so that the sliding block drives the face recognition device body to rotate through the linkage rod.

[0012] A specific structure of a power mechanism that is easy to implement and can be hidden is further provided. The power mechanism includes a motor, a belt, and two pulleys. A motor seat and two pulley seats are fixed to the back of the identification instrument mounting table, and each pulley is rotatably mounted on a pulley seat; the belt is sleeved on the two pulleys and connected to the lower end of the sliding block; the motor is mounted on the motor seat and connected to one of the pulleys.

[0013] In order to facilitate cleaning of the portion of the belt that cannot be rotated to the lower side, a cleaning gap is left between the upper surface of the upper half of the belt and the back side of the identification device mounting platform.

[0014] In order to conveniently hinge the face recognition device body on the recognition device mounting platform, two fixing seats are fixed on the recognition device mounting platform, and two connecting seats are fixed on the bottom of the back side of the face recognition device body. Each connecting seat is hinged to a fixing seat through a hinge axis, and the fixing block is fixed at the middle position of the back side of the face recognition device body.

[0015] In order to further adjust the height of the face recognition device body, the adjustable and retractable face recognition device also includes at least three power telescopic rods that are not in the same straight line, and the telescopic ends of the power telescopic rods are connected to the recognition device mounting platform to drive the recognition device mounting platform to rise and fall.

[0016] Furthermore, the adjustable and retractable face recognition device also includes a base plate, and the fixed end of the power telescopic rod is installed on the base plate.

[0017] In order to facilitate the movement of the entire device, the base plate is further equipped with a plurality of universal wheels.

[0018] In order to enable the sliding block to smoothly link with the face recognition device body, two linkage rods are configured, and the two linkage rods are symmetrically arranged in the left and right directions.

[0019] After adopting the above technical solution, the present invention has the following beneficial effects:

[0020] 1. The power mechanism drives the sliding block to slide, and the sliding block drives the fixed block and the face recognition device body to rotate around the hinge axis between the face recognition device body and the recognition device mounting platform through the linkage rod, so that the face recognition device body can be adjusted to a suitable recognition angle according to the posture of the person to be recognized.

[0021] 2. The entire power mechanism is hidden on the back of the recognition device installation platform, which can improve the aesthetics, reduce the floor space, and will not affect the rotation range of the face recognition device. When not in use, the sliding block can drive the fixed block and the face recognition device body to rotate through the linkage rod until the face recognition device is in a storage state with an angle of 0 degrees or close to 0 degrees with the horizontal plane, thereby avoiding damage during placement.

[0022] 3. The bottom of the face recognition device body is hinged on the recognition device mounting platform. Therefore, when the face recognition device is in the storage state, the overall height of the face recognition device body and the recognition device mounting platform can be as small as possible, almost close to the sum of the thickness of the face recognition device body and the recognition device mounting platform, so as to reduce the storage space as much as possible.

[0031] The face recognition device body 3 has its bottom hinged on the recognition device mounting platform 1, and a fixing block 4 is fixed in the middle or on the top;

[0032] A linkage rod 5, one end of which is hinged to the sliding block 2, and the other end of which is hinged to the fixed block 4;

[0033] The power mechanism is installed on the back of the recognition device mounting platform 1 and is connected to the lower end of the sliding block 2. It is used to drive the sliding block 2 to slide so that the sliding block 2 drives the face recognition device body 3 to rotate through the linkage rod 5.

[0034] Specifically, the power mechanism drives the sliding block 2 to slide, and the sliding block 2 drives the fixed block 4 and the face recognition device body 3 to rotate around the hinge axis of the face recognition device body 3 and the recognition device installation platform 1 through the linkage rod 5, so that the face recognition device body 3 can be adjusted to a suitable recognition angle according to the posture of the person to be recognized. In addition, the entire power mechanism is hidden on the back of the recognition device installation platform 1, which can improve the aesthetics, reduce the floor space, and will not affect the rotation range of the face recognition device body 3. When not in use, the sliding block 2 can drive the fixed block 4 and the face recognition device body 3 to rotate through the linkage rod 5 until the face recognition device 3 is in a storage state with an angle of 0 degrees or close to 0 degrees with the horizontal plane, thereby avoiding damage when placed. In addition, the bottom of the face recognition device body 3 is hinged on the recognition device installation platform 1. Therefore, when the face recognition device is in the storage state, the overall height of the face recognition device body 3 and the recognition device installation platform 1 can be as small as possible, almost close to the sum of the thickness of the face recognition device body 3 and the recognition device installation platform 1, so as to reduce the storage space as much as possible.

[0035] The structure of the power mechanism can be various, as long as it can drive the sliding block 2 to slide along the sliding groove 6 in the horizontal direction. It can be an electric cylinder, an electric push rod, or a Figure 1 and Figure 3 In the structure shown, the power mechanism includes a motor 7, a belt 8, and two pulleys 9.

[0040] Even if dust is accumulated on the belt 8 after long-term use, the dust can be easily cleaned after the corresponding part of the belt 8 is rotated to the lower side. Considering that the part of the belt 8 connected to the sliding block 2 cannot be rotated to the lower side, a cleaning gap is left between the upper surface of the upper half of the belt 8 and the back of the identification instrument mounting table 1. The dust can be removed from the cleaning gap by wiping with a rag or high-pressure blowing, which reduces the difficulty of cleaning and effectively avoids dust accumulation.
