However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0025] The following describes the specific embodiments of the present utility model in combination with the attached drawings. Specific Embodiment 1:

[0027] Referring to Figures 1-4 , an interactive device for real-time face angle information, includes an arc-shaped guide rail 1 and a face interaction device 6. A right-angle mounting flap 2 is provided at the back edge of the arc-shaped guide rail 1, and both side edges of the right-angle mounting flap 2 are bolted to the back of the arc-shaped guide rail 1. A storage groove 3 is provided at the position where the inner bottom surface of the right-angle mounting flap 2 abuts against the arc-shaped guide rail 1. When the entire arc-shaped guide rail 1 is in use, it is installed on an external building through the right-angle mounting flap 2. The right-angle mounting flap 2 is fixed by being bolted to the arc-shaped guide rail 1. The entire device can be installed at the corner position or on the plane of the building surface through the right-angle mounting flap 2. By inserting screws through the bolt holes on the surface of the right-angle mounting flap 2 to connect with the building, the fixation of the entire device is realized. The storage groove 3 provided on the surface is used to store positioning parts such as installation screws, bolts, and nail-free glue, so that the right-angle mounting flap 2 can be directly fixed to the wall by bolts or bonding, realizing the multi-scenario and multi-mode installation of the entire device.

[0028] When the entire device, the face interaction device 6, is adjusted in angle, it is mainly achieved through the arc-shaped track and the adjustment shaft arm 14. The specific structure is that a guiding arc block 4 is slidably arranged inside the arc-shaped guide rail 1. The arc-shaped guide rail 1 provides a guiding track for the movement of the guiding arc block 4 to ensure the normal movement of the guiding arc block 4. An electric control moving wheel 5 is arranged on the bottom surface of the guiding arc block 4, and a motor is arranged between the motor moving wheels. The motor drives the electric moving wheel to move, thereby driving the guiding arc block 4 to move along the arc-shaped guide rail 1, realizing the movement of the entire face interaction device 6 at multiple angles in the position of the entire arc-shaped guide rail 1. A support shaft arm 13 is pivotally connected to the top of the guiding arc block 4. At the same time, an angle adjustment motor 18 is embedded inside the guiding arc block 4, and the output shaft of the angle adjustment motor 18 is connected to the bottom surface of the support shaft arm 13. The outer edges of the adjustment shaft arm 14 and the support shaft arm 13 are both processed with rounded corners. The two side contours of the guiding arc block 4 are the same as the two side contours of the inner wall of the arc-shaped guide rail 1. The support shaft arm 13 can be rotated at an angle on the surface of the guiding arc block 4 by the angle adjustment motor 18. After the entire support shaft arm 13 can move inside the arc-shaped guide rail 1 through the guiding arc block 4, different positions can be adjusted. When passing, the angle of the face interaction device 6 can be adjusted by the angle adjustment motor 18 for self-rotation. Through the adjustment of the two channels, the scanning and recognition range of the face interaction device 6 is increased, and the flexibility of angle recognition is increased. For the movement adjustment inside the arc-shaped track, it can be used for the face information collection at multiple positions and multiple angles when the user keeps the position unchanged, ensuring that the angles between the recognition probe 8 and the user's face are all directly facing angles, increasing the accuracy of information entry. For the self-rotation adjustment of the support shaft arm 13, it can be used for the verification of the user's face and the dynamic verification of face use, etc.

[0029] When the height of the face interaction device 6 is adjusted and used, a plurality of adjustment shaft arms 14 with axially connected ends are arranged at the top end of the support shaft arm 13. A micro-motor rotating shaft 15 is arranged at the end of the adjustment shaft arm 14. A U-shaped shaft rod 16 is arranged at the end of the adjustment shaft arm 14 far from the support shaft arm 13. Both ends of the U-shaped shaft rod 16 are pivotally connected to both sides of the face interaction device 6. A plurality of adjustment shaft arms 14 are provided, and the ends of adjacent adjustment shaft arms 14 are pivotally connected, and the pivotally connected positions of the ends of the adjustment shaft arms 14 are all connected to the micro-motor rotating shaft 15 for driving. The micro-motor rotating shaft 15 drives the adjustment shaft arm 14 to perform precise angle and height adjustment. The plurality of adjustment shaft arms 14 are connected by a pivotal connection method to form a flexible adjustment structure, realizing the face recognition detection in a wide range, improving the recognition accuracy and efficiency, and the flexible adjustment structure adapts to the use requirements of different users.

[0030] When the entire face interaction device 6 is in use, a display panel 7 is provided on the front of the face interaction device 6. Multicolor supplementary lights 9 are provided on both sides of the display panel 7. An identification probe 8 is provided near the center position of the top surface of the display panel 7. The user's face is identified through the identification probe 8, and the information after the user's face recognition is displayed through the display panel 7. An infrared detection probe 17 is embedded at the center position of the front surface of the arc-shaped guide rail 1. The infrared detection probe 17 is electrically connected to the face interaction device 6. The infrared detection probe 17 is used to detect the approach of the user and trigger the activation of the face interaction device 6. A control main board 11 is provided inside the face interaction device 6. A power supply 12 is provided on the back of the control main board 11. The power supply 12 is electrically connected to both the multicolor supplementary lights 9 and the display panel 7. Face recognition is performed through the identification probe 8, and face verification can be performed simultaneously during the recognition. To increase the security of the verification, different colors of ambient light can be provided by the multicolor supplementary lights 9 for verification. The color control and flashing time of the multicolor supplementary lights 9 are controlled by the control main board 11. A control switch 10 is provided on the top surface of the face interaction device 6. The control switch 10 controls the opening and closing of the face interaction device 6. The control switch 10 is electrically connected to the display panel 7. The control main board 11 receives the signal from the infrared detection probe 17 and controls the activation and various functions of the face interaction device 6. The power supply 12 provides stable power. Specific Embodiment Two:

[0032] Referring to Figures 1-4 , for the installation and connection method of the micro motor rotating shaft 15 and the adjusting shaft arm 14, the number of adjusting shaft arms 14 is set according to the actual use adjustment requirements. The micro adjusting motor rotating shaft corresponds to the adjusting shaft arm 14. As Figure 3 shown, the rotating end of the micro motor rotating shaft 15 at the top of the support shaft arm 13 is fixed to the adjusting shaft arm 14 and is pivotally connected to the surface of the adjusting shaft arm 14. The motor bolt at the control end of the micro motor rotating shaft 15 is bolted to the outer surface of the support shaft arm 13. Through the rotation of the micro motor rotating shaft 15, the adjusting shaft arm 14 and the multiple adjusting shaft arms 14 and the face interaction device 6 connected to its surface are driven to rotate and fold, realizing angle and height adjustment. The connection method of the remaining multiple adjusting shaft arms 14 to the micro motor rotating shaft 15 is the same as the above principle. During actual adjustment, according to the detection position, multiple micro motor rotating shafts 15 rotate at different parameter angles simultaneously to realize the height adjustment and front-back distance adjustment of the face interaction device 6. Specific Embodiment Three:

[0034] Referring to Figures 1-4 , based on the content of the above Specific Embodiment One and Two, the following technical content is further disclosed:

[0035] When a user approaches the device, the infrared detection probe 17 will detect the infrared rays emitted by the human body. The infrared detection probe 17 converts the detected signal into an electrical signal and sends it to the control main board 11. The control main board 11 receives the electrical signal from the infrared detection probe 17 and, according to the preset logic, if the signal indicates that a user is approaching, it sends a start instruction to the face interaction device 6. At the same time, the control main board 11 activates the recognition probe 8 and the display panel 7 to prepare for face recognition and information display. The recognition probe 8 starts to work under the instruction of the control main board 11, captures the user's face image, and sends the captured image data to the control main board 11 for further processing. The display panel 7 displays relevant information, such as operation prompts, recognition results, etc. under the instruction of the control main board 11. If the recognition is successful, the display panel 7 can display the user's identity information or other preset content. If the recognition fails or the user needs to perform other operations, the display panel 7 will also display the corresponding prompt information accordingly.

[0036] The control main board 11 receives signals from the infrared detection probe 17, the recognition probe 8, and other possible sensors such as the angle sensor, position sensor, etc., analyzes the received signals, extracts key information such as the user's position, face angle, device status, etc. According to the analyzed information, the control main board 11 calculates the parameters of the micro motor shaft 15 that need to be adjusted, including the rotation angle, rotation speed, rotation direction, etc. These parameters can be preset or dynamically adjusted according to the specific application scenario and requirements. The control main board 11 sends the calculated adjustment parameters to the control units of each micro motor shaft 15, such as the motor driver, in the form of instructions. After receiving the instructions, the control unit of each micro motor shaft 15 drives the motor to rotate according to the specified parameters, thereby driving the adjustment shaft arm 14 or the support shaft arm 13 to adjust the angle and position. During the adjustment process, the control main board 11 may receive feedback signals from the micro motor shaft 15 or other sensors to monitor the progress and effect of the adjustment. According to the feedback signals, the control main board 11 can adjust the adjustment parameters in real time to ensure the accuracy and stability of the adjustment. For the simultaneous adjustment of multiple micro motor shafts 15, the control main board 11 will perform coordinated control to ensure that the actions of each shaft are coordinated and consistent, avoiding mutual interference or conflict.
