These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0032] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Existing advertising displays typically have screens at a fixed height, making them unsuitable for various usage scenarios and lacking flexibility. While many existing advertising devices do possess height-adjusting capabilities to accommodate different heights and viewing angles, most of these devices rely on manual adjustment using handles, cranks, or screws. This method is not only cumbersome, time-consuming, and labor-intensive, but also potentially unstable and poses safety hazards during the adjustment process.

[0034] To address the aforementioned technical problems, this embodiment provides a dual-screen advertising machine. (See reference...) Figures 1 to 3 As shown, Figure 1 This is a perspective view of the dual-screen advertising machine in the embodiments of this application. Figure 2 This is a schematic diagram of the internal structure of the dual-screen advertising machine in an embodiment of this application. Figure 3 This is an exploded view of the dual-screen advertising machine structure in the embodiments of this application.

[0035] The dual-screen advertising machine includes: base 1, guide rail 2, lifting seat 3, slider 4, screen assembly 5, and lifting mechanism 6.

[0036] The base 1 serves as the supporting foundation for the entire dual-screen advertising machine, and is fixed to the ground to ensure the stability of the equipment.

[0037] The guide rail 2 is fixedly connected to the base 1, such as by bolts, and extends along the height direction; the guide rail 2 provides a sliding track for the lifting seat 3, ensuring that the lifting seat 3 moves smoothly in the vertical direction.

[0038] The lifting base 3 is a key component connecting the screen assembly 5 and the lifting mechanism 6. The lifting base 3 is equipped with a slider 4, which cooperates with the guide rail 2, allowing the lifting base 3 to slide up and down along the guide rail 2.

[0039] The screen assembly 5 is connected to the lifting base 3 and has two screens 52 facing opposite directions; the screen assembly 5 can be an LCD display, an LED display or other types of display devices.

[0040] The lifting mechanism 6 is mounted on the base 1 and connected to the lifting seat 3. It drives the lifting seat 3 to move up and down along the guide rail 2 to adjust the height of the screen assembly 5. The lifting mechanism 6 is the power source that drives the lifting seat 3 to move up and down along the guide rail 2, and its operation achieves the adjustment of the height of the screen assembly 5. The lifting mechanism 6 can be an existing linear motion module, and its moving end is connected to the lifting seat 3, such as by bolt fixing.

[0041] It is understandable that, in order to make the lifting seat 3 move more smoothly, the number of guide rails 2 can be increased appropriately, such as setting two guide rails 2 at intervals on the base 1, and the lifting seat 3 is connected to the two guide rails at the same time through two sliders 4.

[0042] The dual-screen advertising machine described above can control the height of the screen component 5 via the lifting mechanism 6. When the user needs to adjust the height of the screen component 5, the lifting mechanism 6 is first activated. Driven by the lifting mechanism 6, the lifting seat 3 begins to slide up and down along the guide rail 2. The tight cooperation between the slider 4 and the guide rail 2, as well as the stable operation of the lifting mechanism 6, ensures the stability and reliability of the screen component 5 during height adjustment. As the lifting seat 3 moves, the height of the screen component 5 connected to it also changes. The user can adjust the height of the screen component 5 by controlling the movement stroke of the lifting mechanism 6 according to actual needs. When the screen component 5 reaches the desired height, the lifting mechanism 6 stops working, fixing the lifting seat 3 and the screen component 5 at the corresponding height. This dual-screen advertising machine, through the coordinated work of the base 1, guide rail 2, lifting seat 3, slider 4, screen component 5, and lifting mechanism 6, achieves flexible height adjustment of the screen component 5, adapting to different usage scenarios and providing users with more convenient and efficient advertising and display services.

[0043] The aforementioned lifting mechanism 6 is a lifting motor, and the drive end of the lifting motor is connected to the lifting base 3. For example, see [reference needed]. Figure 2 As shown, the lifting motor is a screw-driven lifting motor with a self-locking function. After the lifting motor stops working, the lifting platform 3 can maintain its current height. The number of lifting mechanisms 6 can be set according to their driving power and target load; three are shown in the figure.

[0044] To ensure the cleanliness of the lifting platform 3 and screen assembly 5 during movement, please refer to... Figure 1 and Figure 2As shown, the base 1 has a cavity for accommodating the lifting seat 3 and the screen assembly 5. An opening 11 is provided at the top of the cavity, allowing the lifting seat 3 and screen assembly 5 to pass through during lifting. A brush 12 is provided on the opening 11 of the base 1. The brush 12 is located on the moving path of the lifting seat 3 and screen assembly 5 and is used to clean them. For example, the brush 12 is made of a soft and wear-resistant material. When the lifting seat 3 and screen assembly 5 rise or fall through the opening 11, the brush 12 can gently clean their surfaces, removing dust and stains, ensuring the clarity of the promotional content and the viewing experience for the audience.

[0045] For example, see Figure 1 and Figure 2 As shown, screen assembly 5 includes a screen back panel 51 and two screens 52. The screen back panel 51 is connected to the lifting base 3, and the two screens 52 are respectively mounted on the front and back surfaces of the screen back panel 51. Viewers can view the promotional content from two different directions. This greatly improves the coverage and display effect of the promotional content. When specifically selecting screens 52, screen types with different brightness, resolution, and viewing angles can be chosen according to the usage environment and needs.

[0046] To ensure the stability and secure mounting of screen 52 on screen back panel 51, refer to Figure 1 and Figure 2 As shown, the front and back surfaces of the screen back panel 51 are provided with limiting grooves 501 that fit the screen 52, and the screen 52 is fixed in the limiting grooves 501. During installation, the screen 52 can be embedded into the limiting grooves 501 and secured using clips, screws, or other methods. The limiting grooves 501 not only improve the stability of the screen 52 but also facilitate its replacement and maintenance. When the screen 52 needs to be replaced, simply remove the fixing parts to easily remove the screen 52 from the limiting grooves 501. Furthermore, the limiting grooves 501 prevent the screen 52 from shifting or deforming during movement, ensuring accurate display of the promotional content.

[0047] In practical applications, to meet the needs of viewers to view promotional content from different angles and heights, please refer to... Figure 4 As shown, Figure 4 This is a schematic diagram of the rotating structure of the dual-screen advertising machine in this embodiment. The bottom of the screen back panel 51 has a rotating shaft 53 extending along the height direction, and is rotatably connected to the lifting base 3 via the rotating shaft 53. For example, the lifting base 3 has a shaft hole adapted to the rotating shaft 53, and the rotating shaft 53 is rotatably fitted into the shaft hole, with the bottom of the shaft hole serving as support. With this configuration, after the screen back panel 51 protrudes from the base 1, it can rotate within a certain range relative to the lifting base 3, thereby adjusting the display angle of the two screens 52.

[0048] For example, a damping structure is provided between the pivot 53 and the base 1. The damping structure enables the pivot 53 to be fixed in the current position after rotation, thereby achieving the effect of quickly fixing the angle of the screen back panel 51 and the screen 52.

[0049] Further, see Figure 4 As shown, the rotating shaft 53 has a wiring hole 502 inside, which is used to accommodate the wiring of the screen 52. The design of the wiring hole 502 can be adjusted according to the number and type of wiring on the screen 52 to ensure that the wiring is not squeezed or pulled during rotation. In a specific implementation, the connector of the wiring can be fixed to the outside of the rotating shaft 53, and then the wiring can be introduced into the screen back plate 51 through the wiring hole 502 to connect with the screen 52.

[0050] To limit the rotation angle of screen 52, see [link / reference]. Figure 4 As shown, a protrusion 503 is provided on the outer side of the rotating shaft 53, and a stop block 30 is provided on the lifting seat 3. The stop block 30 is on the rotation path of the protrusion 503 and is used to limit the rotation range of the rotating shaft 53, so that the screen 52 can rotate within a preset range, avoid pulling the lines, and quickly position the initial position.

[0051] In some embodiments, the dual-screen advertising machine further includes a proximity sensor 7 fixed to the base. The proximity sensor 7 generates an electrical signal when a user approaches and feeds the signal back to the control device. The control device then changes the content displayed on the screen based on the electrical signal. For example, in standby mode, the screen displays an advertisement. When a user approaches, the proximity sensor 7 is triggered to generate an electrical signal, and the control device then controls the screen to display the user interface based on the signal. This eliminates the need for the user to manually wake the screen, making it more convenient to use.

[0052] In some embodiments, the dual-screen advertising machine also includes a camera 8 mounted on a lifting platform. The camera 8 acquires user images and feeds the image information back to an image processing module, which calculates the number of users based on the user images. For example, the advertising machine is equipped with a high-definition camera 8 to capture real-time images. These images contain information about people in the scene and form the basis for subsequent processing. To obtain clearer images, the camera 8 typically uses high resolution and may be mounted at specific positions and angles to ensure comprehensive and accurate capture of the target area. The acquired images are fed into a built-in, existing image processing module. This module utilizes existing deep learning algorithms to analyze and identify people in the images. These algorithms can identify different people in the image and distinguish the boundaries between them, working effectively even in densely populated or overlapping crowds. Deep learning algorithms simulate the human brain's neural network, performing multi-layered neural network learning and training to analyze and understand complex images. Based on image processing, the advertising machine employs target detection and tracking technology. These technologies, based on visual neural networks, can detect each person in the image in real time and continuously track their movement trajectories. By tracking the movement of people, the advertising machine can more accurately count the number of people passing through a specific area. While tracking the movement of people, the propaganda machine counts the number of people passing through a designated area (such as a specific area in front of the propaganda machine). This is typically achieved by analyzing the direction and speed of the people's movement. When a person enters from one side of the designated area and leaves from the other side, the propaganda machine considers this action a valid count.

[0053] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
