Description

Technical Field

[0001] The utility model relates to the technical field of face recognition devices, in particular to a face recognition device with a protection function. Background Art

[0002] Access control facial recognition devices are intelligent access control systems that incorporate facial recognition technology. They are primarily used to identify users' facial features and automatically open and close doors. How it works: Access control facial recognition devices capture facial images of users with high-definition cameras, process and analyze them using facial recognition algorithms, and compare the results with facial information in a database to identify the user. This process primarily involves four steps: face detection, face alignment, feature extraction, and identity verification.

[0003] The existing facial recognition device consists of a mounting bracket and a main body (taking the access control facial recognition device of the brand Entropy Technology and model xface700 as an example). In actual application, its main body is fixed to the wall by a mounting bracket. Its position is fixed when in use. It is not friendly to taller or shorter people because it is not easy to collect facial information of such people. At the same time, the front of its main body is composed of a complete screen and an outer frame. The screen is completely exposed to the outside and lacks a protective mechanism. It is easy to be damaged by accidental touch. Therefore, a facial recognition device with a protective function is proposed. Utility Model Content

The outer surfaces of the two rotating shafts are fixedly sleeved with winding wheels, and the outer surfaces of the two winding wheels are fixedly wound with a pull rope, and the ends of the pull ropes pass through the shell and are fixedly connected to the metal protective shell. A spring assembly is installed between the two rotating shafts and the shell;

[0007] The outer walls of the two adjacent sides of the shells are both connected to support shafts for limited rotation, and a mounting frame is fixedly connected between the two support shafts.

[0008] Furthermore, both side outer walls of the auxiliary sleeve are provided with sliding grooves, and the sliding grooves match the metal protective shell, and the end of the pull rope is located on the inner side of the sliding groove.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 3 As shown, it relates to a face recognition device with a protective function, including a face recognition device body 1, an auxiliary sleeve 5 is fixedly sleeved on the outer surface of the face recognition device body 1, and the outer walls on both sides of the auxiliary sleeve 5 are jointly limited and slid with a metal protective shell 4, and the outer walls on both sides of the auxiliary sleeve 5 are provided with a slide groove 13, and the slide groove 13 matches the metal protective shell 4. The slide groove 13 has a limiting effect on the metal protective shell 4, which can ensure the stability of the movement of the metal protective shell 4, and the top and bottom of the outer wall of one side of the metal protective shell 4 are fixedly connected with an auxiliary bar 6. The setting of the auxiliary bar 6 can assist the user in pushing or pulling the metal protective shell 4 to move.

[0024] The outer surface of the face recognition device body 1 is fixedly connected to the shell 3 on both sides, and the inner walls of the two sides of the two shells 3 are jointly limited and rotatably connected to the rotating shaft 11. The outer surfaces of the two rotating shafts 11 are fixedly sleeved with the winding wheel 14. The outer surfaces of the two winding wheels 14 are fixedly wound with a pull rope 10, and the end of the pull rope 10 passes through the shell 3 and is fixedly connected to the metal protective shell 4, and the end of the pull rope 10 is located on the inner side of the slide groove 13. A spring assembly is installed between the two rotating shafts 11 and the shell 3. The two spring assemblies include an annular cover 12, and the annular cover 1 2 is sleeved on the outer surface of the rotating shaft 11, and the annular cover 12 is fixedly installed on the inner wall of one side of the shell 3. A volute spring 9 is provided on the inner side of the annular cover 12, and the volute spring 9 is sleeved on the outer surface of the rotating shaft 11. The annular cover 12 has a limiting effect on the volute spring 9, which is beneficial to the installation of the volute spring 9. The two ends of the volute spring 9 are respectively fixedly connected to the annular cover 12 and the rotating shaft 11. When the rotating shaft 11 rotates, a torque is generated on one end of the volute spring 9. Under the action of the torque, the spring material generates bending elastic deformation, causing the spring to twist in the plane.

[0025] The outer walls of the adjacent sides of the two shells 3 are both connected to the support shaft 7 for limited rotation, and the mounting frame 2 is fixedly connected between the two support shafts 7. The outer surfaces of the two support shafts 7 are both covered with rubber sleeves 8, and the two ends of the rubber sleeves 8 are respectively in contact with the mounting frame 2 and the shell 3. The rubber sleeves 8 can increase the rotation resistance of the shell 3, making it difficult to rotate without the action of external force.

[0026] The outer surface of the mounting frame 2 is provided with a plurality of mounting holes, and the arrangement of the mounting holes facilitates the mounting frame 2 to be wall-mounted.

[0027] Working principle: When face recognition is required, the auxiliary bar 6 is used to assist in pushing up or pulling down the metal protective shell 4, and the metal protective shell 4 moves along the slide groove 13, while also pulling one end of the pull rope 10 to move. When one end of the pull rope 10 is pulled and moved, it will passively drive the winding wheel 14 to rotate, thereby driving the rotating shaft 11 to rotate, and the rotating shaft 11 drives one end of the vortex spring 9 to move, causing the vortex spring 9 to undergo elastic deformation until the screen and camera and other mechanisms of the face recognition device body 1 are exposed, and then assists in pushing the face recognition device body 1 to swing around the support shaft 7 as the axis, and performs face recognition operation after reaching the appropriate angle; after the face recognition is completed, the metal protective shell 4 is released, and the vortex spring 9 drives the rotating shaft 11 to reset and rotate under its own elastic force, and the rotating shaft 11 drives the winding wheel 14 to reel the pull rope 10, thereby driving the metal protective shell 4 to reset and move along the slide groove 13 until it is completely reset.
