[0002] With the development of smart terminal technology, interactive intelligent recommendation advertising terminals have been widely used in commercial scenarios and public services. Existing advertising terminals typically integrate functions such as voice recognition and touchscreen interaction, allowing users to query desired information via voice commands or touch operations. Simultaneously, they can push highly relevant advertising information based on user search content and behavioral data. For example, by setting up a scrolling advertising bar on the side of the screen, advertising information can be dynamically displayed without affecting the user's main interface operation, balancing interactive experience and commercial value.

[0003] However, current technical solutions still have significant shortcomings: the display height of existing advertising terminals is usually a fixed value or only supports manual adjustment, failing to automatically adapt the display height to the usage needs of users of different body types (such as adults, children, and people with disabilities with significant height differences). This non-adjustable height design may lead to problems such as poor screen viewing angles and inconvenient touch positions for users, especially for those whose height exceeds the device's preset range, easily causing neck fatigue and decreased operating efficiency. Although some terminals have attempted to achieve manual height adjustment through mechanical structures, this method relies on active user operation and lacks sufficient adjustment precision, making it difficult to meet the personalized needs of diverse scenarios.

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] It also includes an image acquisition module, which is installed on the front side of the display component 3. The image acquisition module is connected to the central processing unit via a data cable. The support component is set as an electric telescopic module, which is connected to the central processing unit via a data cable.

[0026] When a user uses the interactive intelligent recommendation advertising terminal of this utility model, when the user interaction module of the advertising terminal recognizes the interaction information, the user interaction module, which includes a voice recognition module and a display screen touch module, will send the interaction information to the central processing unit. At this time, the central processing unit will send a recognition command to the image acquisition module. The image acquisition module will perform image recognition on the user's height and then send the image back to the central processing unit. The central processing unit will analyze the image information and send execution information to the electric telescopic module according to the analysis results. After receiving the execution information, the electric telescopic module will start to extend and adjust to change the height of the display component 3 so that the height of the display component 3 matches the user's height. At this time, the automatic adjustment process of the display component 3 is completed. The bottom power cord 2 design ensures that the device is continuously powered.

[0027] As a preferred embodiment of the above, the electric telescopic module includes a first sleeve 4 and a second sleeve 5.

[0030] Ease of installation: The modular sleeve structure supports quick on-site assembly, and the connection between the display component 3 and the base can be completed without the need for professional tools.

[0031] As a preferred embodiment of the above, the electric actuator includes a servo motor 6, a current detection module is provided inside the servo motor 6, a fixing plate 7 is installed at the bottom of the servo motor 6, the fixing plate 7 is fixedly installed on the top inner side wall of the first sleeve 4, the output shaft of the servo motor 6 rotates through the fixing plate 7, and a threaded rod 8 is provided at the end of the output shaft of the servo motor 6.

[0032] Precise positioning: The servo motor 6 has high adjustment precision to meet the viewing distance needs of users of different heights;

[0033] Transmission efficiency: The threaded rod 8 transmission is more efficient than the belt transmission and has no risk of slippage, making it suitable for frequent lifting and lowering scenarios;

[0034] Overload protection: The servo motor 6 has a built-in current detection module that automatically cuts off the power supply when the threaded rod 8 gets stuck, preventing the motor from burning out.

[0035] As a preferred embodiment of the above embodiments, the image acquisition module is equipped with a monocular camera 10;

[0036] Cost advantage: Monocular solutions are less expensive than binocular solutions, making them suitable for mass deployment of commercial advertising terminals.

[0037] As a preferred embodiment of the above, the bottom of the fixing plate 7 is provided with a guide shaft 11, and the power plate 9 is provided with a guide hole, which is slidably fitted with the guide shaft 11.

[0038] Smoothness of movement: The guide shaft 11 can greatly improve the longitudinal sliding smoothness of the first sleeve 4 and the second sleeve 5, reduce the wear between the first sleeve 4 and the second sleeve 5, and improve the service life. At the same time, it can also further prevent radial shaking when the threaded rod 8 rotates.

[0039] As a preferred embodiment of the above, a reinforcing ring 12 is provided at the bottom end of the fixing plate 7, and a reinforcing bearing 13 is provided inside the reinforcing ring 12. The reinforcing bearing 13 is mounted on the output shaft of the servo motor 6.

[0040] The reinforcing ring 12 and the reinforcing bearing 13 work together to reduce the longitudinal force on the output shaft of the servo motor 6 inside the servo motor 6, thus protecting the servo motor 6 and reducing the bending deformation caused by long-term stress on the output shaft of the servo motor 6.

[0041] As a preferred embodiment of the above embodiment, the bottom end of the display component 3 is provided with a wire groove 14, the wire groove 14 is located inside the first sleeve 4 and the bottom of the wire groove 14 extends into the second sleeve 5, and the bottom of the wire groove 14 is connected to a corrugated wire hose 15, the bottom of the corrugated wire hose 15 extends and is installed on the top of the placement base 1.

[0043] As a preferred embodiment of the above embodiment, a limiting piece 16 is provided at the bottom of the guide shaft 11;

[0044] The limiting piece 16 is installed on the guide shaft 11, which can prevent the guide shaft 11 and the threaded rod 8 from slipping off the power plate 9 and causing the first sleeve 4 and the second sleeve 5 to separate, thus protecting the advertising terminal.

[0045] The central processing unit of the interactive intelligent recommendation advertising terminal of this invention adopts a single-chip integrated design, and high-performance chips and medium-performance chips are selected according to the actual needs of the advertising terminal.

[0046] During image acquisition and preprocessing: the hardware uses a monocular camera 10, which can be configured with infrared fill lights as needed. The ISP module of the central processing unit performs image denoising and distortion correction, and then outputs RGB format images. At the same time, after the camera acquires images, the central processing unit detects human movement through frame difference method, triggers the height recognition process, performs histogram equalization on the target frame, enhances the contrast of human body edges, and improves the accuracy of subsequent key point detection.

[0047] Human feature extraction and height calculation in the central processing unit:

[0048] Object detection: YOLOv8n lightweight model detects human bounding boxes;

[0049] Key point identification: The OpenPose algorithm extracts 18 key points (top of the head, shoulders, ankles, etc.), and the PAF (part affinity field) algorithm is used to associate the joints.

[0050] Height estimation is based on a monocular visual geometric model, which calculates the actual height by combining the pixel distance between the top of the head and the heel with the camera's installation height and focal length.

[0051] Optimization techniques:

[0052] A sliding window smoothing filter is used to average the height data from five consecutive frames to eliminate random noise.

[0053] By incorporating prior knowledge of human body proportions, outliers are logically corrected.

[0054] Intelligent decision-making and height adjustment of the central processing unit:

[0055] Ergonomic model: The central processing unit calculates the optimal viewing distance based on the height H, and then converts the target height on the display screen using trigonometric functions;

[0056] Motor control: The central processing unit controls the speed of servo motor 6 through PWM signal and calculates the number of pulses in combination with the lead of threaded rod 8.

[0057] This solution achieves adaptive height adjustment of the advertising terminal by integrating cross-domain technologies including monocular vision, deep learning, and precision mechanical transmission. YOLOv8 and OpenPose form the core of visual recognition, while servo motor 6 and threaded rod 8 enable millimeter-level execution, ultimately forming a closed-loop system of "perception-analysis-execution." This system meets the practical needs of commercial scenarios while maintaining controllable costs.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
