Technical Field
[0001] This utility model relates to the field of face and palm print recognition technology, specifically an access control machine based on face and palm print recognition. Background Technology
[0002] The key function of an access control system is to identify personnel information. Only after facial recognition or palm print verification is the door opening signal triggered. This signal controls the door lock to open, making it part of the door lock control system. For example, in a smart office environment, after the access control system identifies employee information, it sends an opening command to the electronic door lock, which then opens.
[0003] Most currently used access control systems cannot adjust the height of the primary display screen according to the user's height. Since users of different heights vary, the inability to adjust the height makes it unsuitable for children or shorter individuals, limiting the system's applicability and flexibility. Furthermore, the system is inconvenient to install on a wall. A cumbersome installation process can lead to lengthy setup times or errors by installers, resulting in an unstable installation. Overall, the access control system suffers from poor installation convenience and durability. Utility Model Content

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example: Figure 1 As shown, the present invention provides the following technical solution, including a housing 1, a lifting mechanism 2 at the bottom of the housing 1, a second display screen 4 fixedly connected to one end of the housing 1, the vertical center line of the second display screen 4 coinciding with the vertical center line of the housing 1, a palm print collection window 5 fixedly connected to one end of the housing 1, a second lens 6 fixedly connected to one end of the housing 1, and a mounting and fixing mechanism 3 on one side of the housing 1.
[0025] Specifically: When the access control unit is needed, it must first be installed and fixed on the wall. The housing 1 is installed and fixed on the wall using the installation and fixing mechanism 3. After the access control unit is installed and fixed, it can be used. People of normal height can scan their fingerprints using the second lens 6 and the second display screen 4 or the palm print collection window 5 on the housing 1. When children or shorter users are using the unit, the height of the first display screen 209 and the first lens 210 needs to be adjusted according to the user's height to facilitate scanning. The height of the first display screen 209 and the first lens 210 is adjusted according to the user's height using the lifting mechanism 2 to complete the operation.
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a lifting mechanism 2 is provided at the bottom of the housing 1. The lifting mechanism 2 includes a bracket 201. The bracket 201 is fixedly connected to the bottom of the housing 1. A motor 202 is fixedly connected to the inner side of the bracket 201. The output shaft of the motor 202 is fixedly connected to a rotating shaft 203 via a coupling. A ball screw 204 is fixedly connected to the bottom end of the rotating shaft 203. A ball nut 205 is movably connected to the outer wall of the ball screw 204. A connecting rod 206 is fixedly connected to the outer wall of the ball nut 205. A slide rail 207 is fixedly connected to the bottom of the housing 1. The outer wall of the slide rail 207 is connected to the inner wall of the connecting rod 206. The sliding connection includes a baffle 208 fixedly connected to the bottom of the slide rail 207, a ball screw 204 rotatably connected to the top of the baffle 208, a first display screen 209 fixedly connected to one side of the connecting rod 206, a first lens 210 fixedly connected to one side of the first display screen 209, two brackets 201 symmetrically arranged about the vertical center line of the motor 202, and a through hole opened inside the connecting rod 206. The shape and size of the through hole match the shape and size of the slide rail 207, and the connecting rod 206 is slidably connected to the slide rail 207 through the through hole.
[0027] Specifically: When children or shorter users are using the device, the height of the first display screen 209 and the first lens 210 needs to be adjusted according to the user's height to facilitate scanning. At this time, the motor 202 is started, causing the rotating shaft 203 to rotate. The rotating shaft 203 drives the ball screw 204 to rotate, and the ball screw 204 drives the ball nut 205 to rise and fall within the ball screw 204. The ball nut 205 drives the connecting rod 206 to rise and fall, allowing the connecting rod 206 to slide in the slide rail 207, making the rise and fall of the connecting rod 206 more stable and smooth. The connecting rod 206 drives the first display screen 209 and the first lens 210 to rise and fall to a suitable height for children or shorter users, thus completing the lifting and lowering operation.
[0028] like Figure 1 , Figure 5 and Figure 6 As shown, a mounting and fixing mechanism 3 is provided on one side of the housing 1. The mounting and fixing mechanism 3 includes a mounting plate 301. The mounting plate 301 is fixedly connected to one side of the housing 1. A threaded hole 302 is opened inside the mounting plate 301. A bolt 303 is threadedly connected to the inner wall of the threaded hole 302. There are two mounting plates 301. The two mounting plates 301 are symmetrically arranged with the vertical center line of the housing 1 as the axis of symmetry.
[0029] When the access control unit is needed, it must first be installed and fixed on the wall. At this time, one side of the mounting plate 301 on the housing 1 should be tightly attached to the wall. Then, the threaded hole 302 on the mounting plate 301 should be aligned with the threaded hole 302 on the wall. Then, the bolt 303 should be rotated and inserted into the threaded hole 302 to fix the mounting plate 301 to the wall, thus completing the installation and fixing work.
[0030] The working principle of this utility model is as follows: When the access control unit is needed, it must first be installed and fixed on the wall. At this time, one side of the mounting plate 301 on the housing 1 is pressed tightly against the wall. Then, the threaded hole 302 on the mounting plate 301 is aligned with the threaded hole 302 on the wall. The bolt 303 is then rotated and inserted into the threaded hole 302, fixing the mounting plate 301 to the wall. This completes the installation and fixing. After the access control unit is installed and fixed, it can be used. People of normal height can be scanned through the second lens 6 and the second display screen 4 or the palm print collection window 5 on the housing 1. When children or shorter users are using the unit, adjustments need to be made according to the user's height. The user adjusts the height of the first display screen 209 and the first lens 210 according to their height to facilitate scanning. At this time, the motor 202 is started, which drives the rotating shaft 203 to rotate. The rotating shaft 203 drives the ball screw 204 to rotate. The ball screw 204 drives the ball nut 205 to rise and fall within the ball screw 204. The ball nut 205 drives the connecting rod 206 to rise and fall, allowing the connecting rod 206 to slide in the slide rail 207, making the rise and fall of the connecting rod 206 more stable and smooth. The connecting rod 206 drives the first display screen 209 and the first lens 210 to rise and fall to a suitable height for use by children or users of shorter stature, thus completing the lifting and lowering operation.
[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
