Technical Field
[0001] This utility model relates to the field of cultural and tourism interactive technology, specifically a two-dimensional interactive all-in-one machine. Background Technology
[0002] With the upgrading of the cultural tourism industry and the surge in demand for interactive experiences, 2D interactive devices have become core equipment in stage performances, outdoor light shows, exhibition halls, and other scenarios. Through real-time linkage between light and shadow output and human movement, they break the limitations of traditional static displays, creating an immersive interactive environment for users. The core value of these devices lies in achieving full coverage of the interactive area and instant feedback of movements through precise angle adjustment and signal response. They are currently widely used in diverse scenarios such as cultural venues, commercial complexes, and outdoor cultural tourism projects, becoming a key carrier for enhancing the attractiveness and experience of these scenarios. However, current 2D interactive devices have fixed installation locations, strict requirements on projection distance and angle, and cumbersome debugging processes, potentially leading to issues such as image distortion or insufficient brightness. Fixed installation limits the size and location of the interactive area, potentially affecting user experience and failing to meet diverse interactive needs. Furthermore, the structural stability of these devices is poor; the bases are mostly simple frame designs with limited load-bearing capacity, and the overall center of gravity is relatively high, making them susceptible to shaking or tilting during the rotation of the main unit, reducing the safety of equipment operation and the stability of light and shadow output. Therefore, we propose a 2D interactive all-in-one machine. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a two-dimensional interactive all-in-one machine. The interactive host can accurately track human body movements and disperse loads through a rigid structure to prevent deformation and improve the anti-overturning ability, which can effectively solve the problems in the background technology.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a two-dimensional interactive all-in-one machine, including a base and an interactive host; Base: Its top wall is rotatably connected to a rotating platform via a hollow shaft. Symmetrically distributed triangular frames are fixedly connected between the upper and lower inner walls of the base. A mounting plate is fixedly connected between the two triangular frames. The upper side of the mounting plate is fitted with the hollow shaft. A counterweight is installed on the bottom wall of the base. The upper side of the counterweight and the lower side of the mounting plate are provided with evenly distributed support tubes. A microcontroller is installed on the front side of the base. The input terminal of the microcontroller is electrically connected to an external power supply. Evenly distributed support legs are fixedly connected to the lower side of the base. Interactive host: It is rotatably connected to the upper left and right inner walls of the rotating platform and works in conjunction with the microcontroller. The front end of the interactive host is equipped with a capture camera. The capture camera works in conjunction with the microcontroller to enable the interactive host to accurately track human movements. This breaks through the limitations of traditional interactive devices with fixed angles and limited coverage. The triangular frame and the mounting plate form a rigid load-bearing structure to distribute the load and prevent deformation. With the help of counterweights and support tubes, the center of gravity is lowered, the anti-overturning ability is improved, and the stable operation of the equipment is ensured.
[0005] Furthermore, a multi-channel conductive slip ring is provided in the middle of the upper side of the mounting plate. The multi-channel conductive slip ring is located inside the hollow shaft. The stator end of the multi-channel conductive slip ring is bidirectionally electrically connected to the microcontroller. The multi-channel conductive slip ring is located inside the hollow shaft and the stator end is bidirectionally electrically connected to the microcontroller, which not only realizes the bidirectional stable transmission of control signals and feedback signals, but also saves installation space by utilizing the hollow shaft structure.
[0006] Furthermore, the input terminals of the interactive host and the capture camera are both electrically connected to the output terminal of the rotor end of the multi-channel conductive slip ring, and the output terminal of the capture camera is electrically connected to the input terminal of the rotor end of the multi-channel conductive slip ring. This ensures that both can continuously obtain power and transmit signals when rotating with the rotating components, completely solving the cable tangling problem and ensuring continuous and stable interactive functions.
[0007] Furthermore, a first worm gear is fixedly connected to the lower end of the outer arc surface of the hollow shaft, and a first worm is provided at the right end of the mounting plate. The first worm is meshed with the first worm gear. The horizontal rotation driving force is improved through the deceleration and torque amplification characteristics of the worm gear transmission, and the reverse self-locking function can accurately lock the position of the hollow shaft to prevent angular deviation caused by external forces.
[0008] Furthermore, the interactive host and the rotating platform are rotatably connected via a rotating shaft. A second worm gear is fixedly connected to a portion of the outer arc surface inside the right side of the rotating platform. A second worm is rotatably connected inside the right side of the rotating platform. The second worm meshes with the second worm gear. The high transmission precision of the worm gear enables fine-tuning control of the pitch angle of the interactive host. At the same time, the self-locking characteristic ensures the stability of the pitch angle and avoids screen shaking.
[0009] Furthermore, a first stepper motor is installed on the right end of the upper side of the mounting plate. The output shaft of the first stepper motor is fixedly connected to the center of the right end face of the first worm gear. The input end of the first stepper motor is electrically connected to the output end of the rotor end of the multi-channel conductive slip ring for stable driving.
[0010] Furthermore, a mounting plate is fixedly connected to the inside of the right side of the rotating platform. The second worm gear is rotatably connected to the upper side of the mounting plate. A second stepper motor is mounted on the lower side of the mounting plate. The output shaft of the second stepper motor is fixedly connected to the center of the lower end face of the second worm gear. The input end of the second stepper motor is electrically connected to the output end of the rotor end of the multi-channel conductive slip ring for stable driving.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This two-dimensional interactive all-in-one machine has the following advantages: 1. The rotating platform and interactive host can rotate 360° horizontally, and the interactive host can be adjusted ±150° to fully cover the interactive needs of different directions and heights. At the same time, the camera captures motion data in real time, enabling the interactive host to accurately track human movements, breaking through the limitations of traditional interactive devices with fixed angles and limited coverage.
[0012] 2. The triangular frame inside the base and the mounting plate form a rigid load-bearing structure, which can effectively distribute the upper load and prevent the base from deforming. The counterweight is connected to the mounting plate through the support tube. With the evenly distributed support legs, the center of gravity of the equipment is greatly reduced, the anti-overturning ability is improved, and the stable and reliable operation of the equipment is ensured.

[0015] 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.
[0016] Please see Figure 1-6 This embodiment provides a technical solution: a two-dimensional interactive all-in-one machine, including a base 1 and an interactive host 4; Base 1: Its top wall is rotatably connected to a rotating platform 3 via a hollow shaft 2 (the hollow shaft 2 and the top wall of base 1 are rotatably connected via a first sealed bearing). A first worm gear 12 is fixedly connected to the lower end of the outer arc surface of the hollow shaft 2. A first worm 13 is provided at the right end of the mounting plate 10. The first worm 13 is meshed with the first worm gear 12. Symmetrically distributed triangular frames 9 are fixedly connected between the upper and lower inner walls of base 1. A mounting plate 10 is fixedly connected between the two triangular frames 9. The upper side of the mounting plate 10 is fitted with the hollow shaft 2 (a bearing is installed in the middle of the upper side of the mounting plate 10 via a bearing seat. The outer arc surface of the outer ring of the bearing is fixedly connected to the lower end of the inner arc surface of the hollow shaft 2). When the first worm gear 13 rotates, it meshes with the first worm wheel 12 at the lower end of the outer arc surface of the hollow shaft 2. The rotational motion of the first worm gear 13 is converted into the circular motion of the first worm wheel 12, which in turn drives the hollow shaft 2 to rotate around its own axis. The top of the hollow shaft 2 is fixedly connected to the rotating platform 3. Therefore, the rotation of the hollow shaft 2 directly drives the rotating platform 3 and the interactive host 4 installed on it to achieve 360° horizontal rotation (adapting to a large area of interactive coverage). At the same time, the transmission between the first worm wheel 12 and the first worm gear 13 has "reverse self-locking property", which can lock the position of the hollow shaft 2 when the first worm gear 13 stops rotating, avoiding rotational deviation caused by external forces (such as a slight breeze). A counterweight 19 is installed on the bottom wall of the base 1. The upper side of the counterweight 19 and the lower side of the mounting plate 10 are provided with evenly distributed support tubes 20. The symmetrical triangular frame 9 inside the base 1 and the mounting plate 10 form a rigid load-bearing structure, providing a stable installation foundation. At the same time, the geometric stability of the triangular frame 9 can distribute the gravity load on the upper part of the equipment and prevent the base 1 from deforming. The counterweight 19 on the bottom wall of the base 1 is connected to the mounting plate 10 through the evenly distributed support tubes 20, which further lowers the overall center of gravity of the equipment and greatly improves the anti-overturning ability of the equipment during horizontal rotation and pitch adjustment, ensuring the structural stability when interactive actions are performed. A microcontroller 6 is mounted on the front side of the base 1. The input terminal of the microcontroller 6 is electrically connected to an external power supply. The microcontroller 6 provides core control for the entire device. A multi-channel conductive slip ring 11 is provided in the middle of the upper side of the mounting plate 10. (The rotor end of the multi-channel conductive slip ring 11 consists of multiple sets of mutually insulated conductive rings arranged coaxially. Each metal ring corresponds to an independent channel and can carry power or different types of signals. The stator end is equipped with a brush assembly matching the number of conductive rings. Each brush is individually and tightly attached to the surface of its corresponding conductive ring through an elastic structure to avoid interference between channels. These conductive rings are isolated and cured layer by layer by insulating materials such as epoxy resin, fitted onto the hollow rotating shaft, and then encapsulated by a sealed shell.) The stability of simultaneous transmission of multiple channels is ensured by independent rings and brushes, and electrical isolation of each channel is achieved by insulation structure and matching components, ultimately achieving uninterrupted transmission of multi-loop signals and power in the rotating state. The multi-channel conductive slip ring 11 is located inside the hollow shaft 2. The stator end of the multi-channel conductive slip ring 11 is bidirectionally electrically connected to the microcontroller 6. Due to the sliding contact structure of the brush and conductive ring built into the multi-channel conductive slip ring 11, 360° uninterrupted transmission of power and control signals is achieved, fundamentally avoiding the cable tangling problem when traditional equipment rotates. A first stepper motor 14 is installed on the upper right side of the mounting plate 10. The output shaft of the first stepper motor 14 is fixedly connected to the center of the right end face of the first worm 13. The input end of the first stepper motor 14 is electrically connected to the output end of the rotor end of the multi-channel conductive slip ring 11. After receiving the control signal from the microcontroller 6, the first stepper motor 14 starts to run. Its output shaft drives the first worm 13 to rotate synchronously, providing a stable driving force for the first worm 13. Interactive host 4: It is rotatably connected to the upper left and right inner walls of the rotating platform 3 and works in conjunction with the microcontroller 6 (the microcontroller 6 can be equipped with an encoder and sensor to monitor the position and status of the interactive host 4 in real time, ensuring the accuracy and stability of the movement). The interactive host 4 and the rotating platform 3 are rotatably connected through a rotating shaft 7 (the rotating shaft 7 and the rotating platform 3 are rotatably connected through a second sealed bearing). The rotating shaft 7 is fixedly connected to a second worm gear 15 on a part of the outer arc surface inside the right side of the rotating platform 3. The rotating shaft 16 is rotatably connected to the inside of the right side of the rotating platform 3. The second worm gear 16 is meshed with the second worm gear 15. The rotation of the second worm gear 16 drives the second worm gear 15 to rotate synchronously under the meshing action. The rotation of the second worm gear 15 causes the rotating shaft 7 to rotate accordingly, thereby causing the interactive host 4 to undergo a tilt angle change of ±150°. At the same time, the "reverse self-locking" property of the second worm gear 15 and the second worm gear 16 can lock the position of the rotating shaft 7 when the second worm gear 16 stops rotating, avoiding rotational deviation caused by external force. The rotation of the rotating shaft 7 is directly driven. The front end of the interactive host 4 is equipped with a capture camera 5, which works in conjunction with the microcontroller 6. The input ends of both the interactive host 4 and the capture camera 5 are electrically connected to the output end of the rotor end of the multi-channel conductive slip ring 11, and the output end of the capture camera 5 is electrically connected to the input end of the rotor end of the multi-channel conductive slip ring 11. The capture camera 5 at the front end of the interactive host 4 collects human motion data (such as limb swings, positional movements, etc.) in the surrounding environment in real time, and converts the collected image / motion signals into electrical signals. The electrical signals are transmitted to the rotor end of the multi-channel conductive slip ring 11 through wires, and then transmitted to the stator end through the signal path inside the slip ring, and finally fed back to the microcontroller 6. This allows for the adjustment of the pitch angle of the interactive host 4 (such as changing from horizontal projection to upward tilt projection). With the real-time signal feedback from the capture camera 5, the effect of "the interactive host 4 accurately chasing human motion" can be achieved. A mounting plate 18 is fixedly connected to the inside of the right side of the rotating platform 3. The second worm gear 16 is rotatably connected to the upper side of the mounting plate 18. A second stepper motor 17 is mounted on the lower side of the mounting plate 18. The output shaft of the second stepper motor 17 is fixedly connected to the center of the lower end face of the second worm gear 16. The input end of the second stepper motor 17 is electrically connected to the output end of the rotor end of the multi-channel conductive slip ring 11. After receiving the control signal from the microcontroller 6, the second stepper motor 17 starts to run. Its output shaft drives the second worm gear 16 to rotate synchronously, providing a stable driving force for the second worm gear 16. The lower side of the base 1 is fixedly connected with evenly distributed support legs 8, which provide support for the equipment.
[0017] The working principle of the two-dimensional interactive all-in-one machine provided by this utility model is as follows: After the device is connected to an external power source, the current is first delivered to the microcontroller 6 on the front side of the base 1. At the same time, the output end of the microcontroller 6 is connected to the stator end (fixed) of the multi-channel conductive slip ring 11 through wires, while the rotor end of the conductive slip ring 11 (rotating with the hollow shaft 2) is connected to the input ends of the interactive host 4, the capture camera 5, the first stepper motor 14, and the second stepper motor 17, respectively. Due to the sliding contact structure between the built-in brush and the conductive ring in the multi-channel conductive slip ring 11, even if the hollow shaft 2 and the rotating platform 3 rotate subsequently, the power and control signals can still be transmitted 360° uninterruptedly through this "rotation bridge", thus fundamentally avoiding the cable entanglement problem during the rotation of traditional devices. The interactive host 4 uses a front-end camera 5 to capture real-time motion data of the human body in the surrounding environment (such as limb swings and positional movements). The captured image / motion signals are converted into electrical signals, which are transmitted via wires to the rotor end of a multi-channel conductive slip ring 11. From there, the signals are transmitted through the slip ring's internal signal path to the stator end, and finally fed back to the microcontroller 6. The microcontroller 6 has a built-in preset interactive algorithm that quickly analyzes the received motion signals (such as identifying the direction, amplitude, and speed of the motion) and generates corresponding control commands based on the analysis results (including horizontal rotation commands for the rotating platform 3 and pitch adjustment commands for the interactive host 4). When the microcontroller 6 outputs a horizontal rotation command, the control signal is transmitted via the multi-channel conductive slip ring 11 to the first stepper motor 14, triggering... When the first stepper motor 14 starts, its output shaft drives the first worm gear 13, which is fixedly connected to it, to rotate synchronously. Since the first worm gear 13 meshes with the first worm wheel 12 at the lower end of the outer arc surface of the hollow shaft 2, the rotational motion of the first worm gear 13 is converted into the circular motion of the first worm wheel 12, thereby driving the hollow shaft 2 to rotate around its own axis. The top of the hollow shaft 2 is fixedly connected to the rotating platform 3. Therefore, the rotation of the hollow shaft 2 directly drives the rotating platform 3 and the interactive host 4 mounted on it to achieve a 360° horizontal rotation (suitable for large-area interactive coverage). Simultaneously, the transmission between the first worm wheel 12 and the first worm gear 13 has a "reverse self-locking property," which locks the position of the hollow shaft 2 when the first stepper motor 14 stops working, preventing damage from external forces (such as…). The rotational offset caused by a slight breeze is controlled by the microcontroller 6 when it outputs a pitch adjustment command. The control signal is transmitted to the second stepper motor 17 via the multi-channel conductive slip ring 11, which drives the second stepper motor 17 to start. The output shaft of the second stepper motor 17 drives the second worm gear 16 (mounted on the mounting plate 18 inside the rotating platform 3) which is fixedly connected to it to rotate. The second worm gear 16 meshes with the second worm wheel 15 on the outer arc surface of the rotating shaft 7, converting the rotational motion of the second stepper motor 17 into the rotation of the second worm wheel 15, which in turn drives the rotating shaft 7 to rotate around its own axis. Since the interactive host 4 is rotatably connected to the left and right inner walls of the rotating platform 3 through the rotating shaft 7, the rotation of the rotating shaft 7 directly drives the interactive host 4 to achieve pitch angle adjustment (such as changing from horizontal projection to upward tilt projection).With the real-time signal feedback from the capture camera 5, the interactive host 4 can precisely track human movements. The symmetrical triangular frame 9 inside the base 1 and the mounting plate 10 form a rigid load-bearing structure, providing a stable mounting foundation for the hollow shaft 2, multi-channel conductive slip ring 11, and first stepper motor 14. The geometric stability of the triangular frame 9 can distribute the gravitational load on the upper part of the device, preventing deformation of the base 1. Simultaneously, the counterweight 19 on the bottom wall of the base 1 is connected to the mounting plate 10 through evenly distributed support tubes 20, further lowering the overall center of gravity of the device. Combined with the support feet 8 on the lower side of the base 1 (increasing the ground contact area), this significantly improves the device's anti-tipping ability during horizontal rotation and pitch adjustment, ensuring structural stability during interactive actions.
[0018] It is worth noting that the capture camera 5 disclosed in the above embodiments can be model C920, the first stepper motor 14 and the second stepper motor 17 can both be model 42BYGH4001, and the microcontroller 6 can be model STC89C52RC. The microcontroller 6 controls the capture camera 5, the first stepper motor 14 and the second stepper motor 17 using methods commonly used in the prior art.
