[0025] Example

[0026] See Figure 1-4 As shown:

[0027] This utility model provides an external protective structure for biometric access control, including: a protective box 10 and a moving component.

[0028] The protective box 10 has a cavity for installing the access control device A, and a transparent cover 20 that can open and close the cavity opening is provided at the opening of the cavity.

[0029] In practical applications, the top of the transparent cover 20 is hinged to the edge of the open top of the protective box 10 via the hinge 21, and the side of the transparent cover 20 is provided with a protrusion 22, which becomes the force point for lifting the transparent cover 20, thereby facilitating the opening of the transparent cover 20.

[0030] Access control device A is equipped with a facial recognition camera a1, a keypad a2, a fingerprint scanner a3, and a display screen a4 for controlling the opening and closing of the entrance / exit door. The facial recognition camera a1, keypad a2, fingerprint scanner a3, and display screen a4 are positioned at the opening of the protective box 10. In use, the facial recognition camera a1 directly recognizes the user's face through the transparent cover 20 and displays the recognized information on the display screen a4. If the facial recognition camera a1 fails to recognize the user, the operator can open the transparent cover 20 and use the keypad a2 or fingerprint scanner a3 to open the entrance / exit door. This design protects access control device A from moisture and dust, extending its lifespan.

[0031] In practical use, the transparent cover 20 can prevent dust and moisture from entering the access control device A, thereby ensuring the stability of the face recognition camera a1, password button a2, fingerprint recognition a3 and display screen a4 on the access control device A, improving the accuracy of the access control device A, and thus improving the usage effect.

[0032] One end of the movable component is slidably connected to the wall next to the entrance / exit, and the other end is hinged to the protective box 10. This allows the height and angle of the access control device A in the protective box 10 to be adjusted during use, improving the accuracy of the face recognition camera a1. If the face recognition camera a1 fails to pass the first time, users can quickly pass the recognition by simply adjusting the position of the protective box 10.

[0033] The movable component includes a fixed part and a connecting part; the fixed part is installed in the wall next to the entrance / exit and is arranged vertically along the wall. One end of the connecting part is slidably connected to the fixed part, and the other end is hinged to the protective box 10.

[0034] The connecting part mainly consists of a first connecting rod 31, a second connecting rod 32, and a movable seat 33. One end of the first connecting rod 31 is perpendicularly connected to one side of the protective box 10, generally the back of the protective box 10, and the other end is hinged to one end of the second connecting rod 32. The other end of the second connecting rod 32 is hinged to the movable seat 33; the movable seat 33 is slidably connected to the fixed part. The movable seat 33 is provided with two hinge notches 331; the end of the second connecting rod 32 is rotatably connected to the sidewalls of the two hinge notches 331.

[0035] With this configuration, both ends of the second connecting rod 32 can be adjusted to change the operating angle of the protective box 10, i.e., the operating angle of the access control device A. Furthermore, when not in use, the protective box 10 can be parallel to the wall, resulting in a more aesthetically pleasing appearance. To ensure the protective box 10 maintains its position after angle adjustment, both ends of the second connecting rod 32 have strong damping at their rotating joints. This means that external force is required to bend the protective box 10 to adjust its operating angle, thus ensuring stability during use.

[0036] The fixing part includes a mounting box 40 and an elastic limiting member.

[0037] In practical use, the mounting box 40 is embedded in the wall next to the entrance. The mounting box 40 has a guide groove 41 along the vertical direction, and the connecting part can be stored in the guide groove 41, so that the mounting box 40 can fit snugly against the wall, making it more aesthetically pleasing. Mounting grooves 43 are provided on both sides of the guide groove 41; elastic limiting members are installed in the mounting grooves 43. Sliding rods 332 are provided on both sides of the movable base 33; elongated holes are provided along the length of the side walls on both sides of the guide groove 41, connecting the guide groove 41 and the mounting groove 43, and the ends of the sliding rods 332 pass through the elongated holes and connect with the elastic limiting members in the mounting groove 43.

[0038] In practical use, the elastic limiting component is set as an upper spring 431. One end of the upper spring 431 is connected to the inner wall of the top of the mounting groove 43, and the other end of the upper spring 431 is connected to the end of the slide rod 332 located in the mounting groove 43.

[0039] With this setup, the entire protective box 10 is positioned in the middle of the mounting slot 43. When in use, simply pull down or push up the protective box 10 to adjust the position of the access control device A in the vertical direction, so that the face recognition camera a1 can accurately recognize the face of the user.

[0040] To ensure greater stability of the protective box 10 when not in use, a lower spring 432 is provided. One end of the lower spring 432 is connected to the inner wall of the bottom of the mounting groove 43, and the other end is connected to the end of the slide rod 332 located in the mounting groove 43. Both the upper spring 431 and the lower spring 432 are in a stretched state. In use, simply pulling down or pushing up the protective box 10 adjusts the vertical position of the access control device A, enabling the face recognition camera a1 to accurately recognize the user's face.

[0041] After being pulled down or pushed up, the protective box 10 can still return to its original position, improving the stability of use.

[0042] At the top of the guide groove 41, there is a through hole 411 through which the power cord passes. In actual use, the power cord passes through the through hole 411 from the wall and is electrically connected to the access control device A. The power cord can be extended or set as a spiral-shaped automatically retractable power cord to adapt to the movement of the protective box 10.

[0043] It also includes a cover plate 42, which is designed with an opening to close the opening of the mounting slot 43 and forms a detachable connection with the mounting box 40. This design allows for the installation or replacement of the flexible connectors during actual use, improving the convenience of daily installation and maintenance of the entire biometric access control external protection structure and extending its service life.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
