Description

Technical Field

[0001] This application belongs to the field of identity recognition technology, specifically an adjustable-angle identity recognition device. Background Technology

[0002] Identity recognition mainly includes biometric recognition, such as facial recognition which identifies identity by capturing facial feature points, fingerprint recognition which relies on unique fingerprint patterns, iris recognition which is based on the complex texture structure of the human iris, and voiceprint recognition which is based on the timbre, tone, and other characteristics of the voice.

[0003] For example, utility model patent CN221323875U discloses an adjustable-angle identity recognition device, including a support structure and an image recognition device. The support structure includes a slide rail, an elastic clamping member, and a sliding frame. The slide rail is a flat structure fixed to the ground or wall, and the sliding direction is perpendicular to the ground. The sliding frame is fitted into the slide rail and can slide along the slide rail. An elastic clamping member for clamping the slide rail is fixedly connected below the sliding frame. The image recognition device is fixedly connected above and below the sliding frame. When the index finger and thumb are used to pinch the U-shaped spring plate inward, the fixing claws and fixing teeth are disengaged from their interlocking state. At this time, the image recognition device can be pulled down directly. When the pressure of the index finger and thumb on the U-shaped spring plate is released, the U-shaped spring plate, under the action of elasticity, will embed the two fixing claws into the fixing teeth on both sides of the through groove. When the image recognition device needs to move upward, it can be pushed upward directly without pressing the U-shaped spring plate.

[0004] However, in actual use, it was found that the elastic force of the U-shaped spring plate of the device would decrease over time or with frequent use, resulting in a loose engagement between the fixing claw and the fixing tooth. This could cause the image recognition device to loosen or shift during long-term use, affecting the recognition accuracy. Furthermore, it requires the user to pinch the U-shaped spring plate with their index finger and thumb and pull the device, which is difficult for users with weak hand strength. Therefore, an adjustable-angle identity recognition device is provided. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] refer to Figures 1-4As shown, an adjustable-angle identity recognition device includes a fixed vertical plate 1, a U-shaped fixing frame 11 fixedly installed on the rear side of the fixed vertical plate 1, a plurality of through holes 12 opened on one side of the U-shaped fixing frame 11, and a flexible protective pad 15 fixedly installed on the side of the U-shaped fixing frame 11 away from the fixed vertical plate 1. The plurality of through holes 12 facilitate the fixing of the device to different mounting surfaces by means of bolts or other connecting parts, thereby improving the flexibility and applicability of the device installation. The rubber pad 15 can protect the mounting surface from being scratched during installation and also plays a certain role in buffering and shock absorption.

[0022] refer to Figures 1-4 As shown, an L-shaped support plate 2 is fixedly installed on the front side of the fixed vertical plate 1, and an adjusting slider 3 is provided on the front side of the fixed vertical plate 1. Two L-shaped limiting plates 4 are fixedly installed on the front side of the adjusting slider 3. Through the cooperation of the adjusting slider 3 and the L-shaped limiting plates 4, the adjusting slider 3 can slide along the fixed vertical plate 1, which facilitates the subsequent position adjustment of the identity recognition device. The L-shaped limiting plates 4 can further limit the sliding of the adjusting slider 3 to prevent it from detaching from the fixed vertical plate 1 during the sliding process, thus ensuring the safety and reliability of the device operation.

[0023] refer to Figures 1-4 As shown, a mounting plate 5 is fixedly installed on the top surface of the adjusting slider 3. Two triangular reinforcing plates 13 are fixedly installed on the front side of the L-shaped limiting plate 4 near the corner, and the top surfaces of the two triangular reinforcing plates 13 are fixed to the bottom surface of the mounting plate 5. A fixing seat 6 is hinged to the top surface of the mounting plate 5. An identity recognition camera 7 is fixedly installed on the front side of the fixing seat 6. An angle adjustment mechanism 8 connected to the fixing seat 6 is provided on the top surface of the mounting plate 5. The triangular reinforcing plates 13 can effectively enhance the connection strength between the mounting plate 5 and the adjusting slider 3, improve the stability of the overall structure, and withstand greater external forces. The angle adjustment mechanism 8 can realize the vertical angle adjustment of the fixing seat 6 and the identity recognition camera 7, meet the diverse needs of the identity recognition camera 7 shooting angle in different usage scenarios, and improve the accuracy and effectiveness of identity recognition.

[0024] refer to Figures 1-4As shown, the angle adjustment mechanism 8 includes a connecting block 801, an internal threaded rod 802, an external threaded adjusting rod 803, a connecting rotating seat 804, and a bearing 805. The connecting block 801 is fixedly installed on the top surface of the adjusting slider 3. The internal threaded rod 802 is fixedly installed through one side of the connecting block 801. The internal thread of the internal threaded rod 802 is connected to the external threaded adjusting rod 803. The connecting rotating seat 804 is rotatably connected to one side of the fixed seat 6. The bearing 805 is fixedly installed at one end of the external threaded adjusting rod 803. The bearing 805 is hinged to one side of the connecting rotating seat 804. By rotating the external threaded adjusting rod 803, the extension length of the external threaded adjusting rod 803 can be precisely controlled by its threaded engagement with the internal threaded rod 802, thereby achieving fine adjustment of the angle of the fixed seat 6 and the identity recognition camera 7. The bearing 805 reduces the rotational friction between the connecting rotating seat 804 and the external threaded adjusting rod 803, making the angle adjustment process smoother and improving the service life of the angle adjustment mechanism 8.

[0025] refer to Figures 1-4 As shown, a rack 9 is fixedly installed on the front side of the L-shaped support plate 2. An adjusting limiting mechanism 10 connected to the rack 9 is provided on one side of the L-shaped limiting plate 4. The adjusting limiting mechanism 10 includes a hinge seat 101, a limiting rod 102, a base plate 103, and a spring 104. Two hinge seats 101 are fixedly installed on the front side of the L-shaped limiting plate 4, and the sides of the two hinge seats 101 that are close to each other are rotatably connected to the limiting rod 102. Through the cooperation of the rack 9 and the adjusting limiting mechanism 10, when the adjusting slider 3 slides to the desired position, the bottom end of the limiting rod 102, under the elastic force of the spring 104, can accurately insert between the two protruding teeth of the rack 9, like a slot design, firmly locking the adjusting slider 3 and effectively resisting external interference such as collisions and vibrations. The slider 3 is free from displacement, ensuring that the identity recognition camera 7 mounted on it remains in a stable position and guaranteeing the accuracy of identity recognition. At the same time, the spring 104 continuously provides a reset force to the limit rod 102, keeping the limit rod 102 engaged with the rack 9 at all times. During the upward adjustment of the slider 3, the user does not need to manually operate the limit rod 102 to lock it. Simply push the slider 3 to the target position, and the limit rod 102 will automatically engage with the rack 9 under the action of the spring force, simplifying the cumbersome adjustment steps. When further adjustment is needed, apply external force to overcome the spring force and lift the limit rod 102 to easily unlock it. The entire operation process is convenient and efficient, significantly improving the ease of use of the device and the user experience.

[0026] refer to Figures 1-4As shown, a base plate 103 is fixedly installed on the front side of the L-shaped limiting plate 4. A spring 104 is fixedly installed on one side of the base plate 103. The end of the spring 104 away from the base plate 103 is fixed to one side of the limiting rod 102. A flexible pad 14 is fixedly installed on the side of the limiting rod 102 away from the spring 104. The base plate 103 provides a stable mounting base for the spring 104, ensuring that the spring 104 can function normally. The flexible pad 14 increases the comfort of personnel when pressing the limiting rod 102.

[0027] The implementation principle of an adjustable-angle identity recognition device according to this application is as follows: During installation, the device is fixed in a suitable position through the through hole 12 on the U-shaped fixing bracket 11. When it is necessary to adjust the horizontal position of the identity recognition camera 7, the adjusting slider 3 can be manually pushed to slide along the fixed vertical plate 1. The L-shaped limiting plate 4 limits the adjusting slider 3 during the sliding process. When the adjusting slider 3 slides to the desired position, the bottom end of the limiting rod 102 can be precisely inserted between the two protruding teeth of the rack 9 under the elastic force of the spring 104. Like a slot design, the adjusting slider 3 is firmly locked, effectively resisting... External forces such as collisions and vibrations prevent the adjustment slider 3 from shifting, thus ensuring that the identity recognition camera 7 installed on it maintains a stable position and guarantees the accuracy of identity recognition. At the same time, the spring 104 continuously provides a reset force to the limit rod 102, so that the limit rod 102 always maintains the engagement tendency with the rack 9. During the upward adjustment of the adjustment slider 3, the user does not need to manually operate the limit rod 102 to lock it. He only needs to push the adjustment slider 3 to the target position, and the limit rod 102 will automatically engage with the rack 9 under the action of the spring force, simplifying the cumbersome adjustment steps.

[0028] When readjustment is needed, the user presses the limit rod 102 to apply external force to overcome the elastic force of the spring 104 and lift the limit rod 102, easily releasing the lock. The entire operation process is convenient and efficient, significantly improving the ease of use and user experience of the device. If the vertical angle of the identity recognition camera 7 needs to be adjusted, the external threaded adjustment rod 803 can be rotated. The external threaded adjustment rod 803 and the internal threaded rod 802 are threaded together, driving the connecting rotating seat 804 and the fixed seat 6 to rotate, thereby realizing the vertical angle adjustment of the identity recognition camera 7 to meet the identity recognition needs in different scenarios. The device adopts a cooperative structure of spring 104, limit rod 102 and rack 9, which can maintain stable and durable elastic support and locking performance, and can maintain a reliable fixing effect for a long time. It realizes automatic locking of the slider by pushing it in one step, reducing the difficulty of operation and improving practicality and user experience.
