Description

Technical Field

[0001] This invention relates to the field of intelligent display device technology, specifically to an intelligent digital exhibition hall interactive display device and its usage method. Background Technology

[0002] In today's era of sweeping digitalization, the integration of technology and culture is becoming increasingly close. Intelligent digital exhibition halls, as important venues for showcasing cutting-edge technologies and disseminating cultural knowledge, are gradually becoming key windows for various industries to demonstrate their image and strength. With the rapid development of information technology, traditional display methods can no longer meet people's increasingly diverse needs. Audiences are no longer satisfied with simple static displays and passively receiving information; instead, they crave more vivid and interactive display experiences. Intelligent digital exhibition hall interactive display devices have emerged to address this need. They break through the limitations of traditional displays, integrating advanced technologies such as virtual reality, augmented reality, and artificial intelligence to bring audiences an immersive interactive experience. In the field of cultural dissemination, intelligent digital exhibition hall interactive display devices can present historical artifacts and works of art in a more vivid and intuitive way. In the field of technology display, they can present complex scientific principles and technological achievements through interactive demonstrations, allowing audiences to learn and understand in a relaxed and enjoyable atmosphere. At the same time, with the improvement of people's living standards and changes in consumption concepts, there are also higher requirements for the quality and experience of the display environment. Intelligent digital exhibition hall interactive display devices not only provide high-quality visual effects but can also intelligently adjust according to the behavior and needs of the audience, achieving personalized display services.

[0003] However, existing technologies still have some shortcomings. In terms of cleaning, traditional interactive display devices severely lack automatic cleaning functions. During daily use, smart displays easily attract a large amount of dust due to static electricity. When users operate on the screen with writing tools, each press causes the dust to rub violently against the screen surface. Over time, the screen surface will gradually be covered with fine scratches. These scratches not only severely reduce the screen's display clarity, making the displayed content blurry and affecting the viewer's experience, but also, in terms of writing experience, existing devices lack good writing feedback. Users often unconsciously increase the writing pressure to ensure effective operation, causing the screen to endure more friction. After prolonged use, scratches will gradually appear on the screen surface, exacerbating the scratch problem and seriously affecting the device's lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent digital exhibition hall interactive display device and its usage method to solve the problems mentioned in the background art.

[0009] Furthermore, the upper end of the ventilation duct slides at the center of the top slide, and an air outlet is provided at the upper end of the ventilation duct. The bottom end of one side of the ventilation duct is located inside the auxiliary slide, and a slot is provided on the bottom surface of the auxiliary slide. The bottom end of the ventilation duct passes through the slot on the bottom surface of the auxiliary slide.

[0010] Furthermore, the dust collection box is internally connected to the dust collection box. An air inlet is provided on one side surface of the dust collection box, and a small fan is installed inside the air inlet. A fine mesh plate is installed inside the dust collection box, and multiple connecting springs are provided on one side surface of the fine mesh plate. One end of each connecting spring is connected to one side surface of the fine mesh plate, and the other end is connected to the inner side surface. A flip plate is provided inside the dust collection box, and a torsion spring is provided at the connection between the flip plate and the dust collection box. A striking rod shaft is also provided on the inner side surface of the dust collection box, and multiple striking hammers are provided on the surface of the striking rod shaft.

[0011] Furthermore, one end of the buffer duct is provided with a sensing tube body, the surface of the sensing tube body is provided with multiple shielding blocks, the interior of the air outlet is provided with a miniature telescopic rod for driving the shielding blocks to extend and retract, the upper surface of the sensing tube body is also provided with a sensing groove, the interior of the sensing groove is provided with a sensing fan blade, the sensing fan blade is electrically connected to the miniature telescopic rod inside the sensing tube body, and one side surface of the sensing tube body is provided with a contact ball head.

[0012] Furthermore, the additional mechanism also includes a side plate component, which includes two connecting side blocks, which are respectively disposed on the left and right sides of the smart display screen. A fixed connecting plate is provided on one side surface of each of the two connecting side blocks, and a reinforcing bracket is provided on one side surface of the fixed connecting plate. The reinforcing bracket is connected to the top or bottom surface of the smart display screen.

[0013] Furthermore, each of the two connecting side blocks is provided with an electric shaft on both sides, and a light-blocking plate is provided on one side surface of the electric shaft. An infrared sensor and a capacitive proximity sensor are respectively provided on one side surface of the two connecting side blocks.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This solution addresses the pain points of traditional exhibition hall screen cleaning, such as reliance on manual labor and easy surface scratching, by incorporating a cleaning component. When the user removes the pen from the support buffer plate, the mechanical trigger structure of the fixing buckle activates the sensor inside the top carriage, initiating a collaborative positioning system using infrared and capacitive sensors. The infrared sensor adjusts its monitoring angle in real time via an electric turntable to accurately locate the user's pen-holding position and transmits the coordinate data to the drive motor. The capacitive sensor then confirms the writing area boundary a second time through changes in the electric field, ensuring that the cleaning range covers the pen tip's trajectory. Upon receiving the positioning signal, the drive motor drives the engaging thread. The rotating rod drives the ventilation duct to move laterally along the auxiliary slide to the target position. First, a high-pressure airflow is sprayed out from the air outlet, using the impact force of the airflow to break the electrostatic adsorption structure of the dust on the screen surface, causing it to suspend. Then, the micro fan in the dust collection box generates negative pressure through the air inlet, sucking the dust into the dust collection box. The fine mesh plate adopts an elastic connection design. When the dust accumulation causes the wind resistance to increase, the fine mesh plate compresses the connecting spring and triggers the rotating of the striking rod shaft, causing the striking hammer to periodically vibrate the fine mesh plate, shaking the dust into the dust collection box, realizing the self-cleaning of the filter, reducing the frequency of manual intervention, and avoiding physical contact that scratches the screen, thus extending the service life of the equipment.

[0016] 2. In this solution, by incorporating a writing component, the touch writing experience and screen protection are optimized. When the pen tip approaches the screen, the sensing fan blades inside the sensing tube rotate under the influence of external airflow, triggering the extension of the micro telescopic rod and unfolding the shielding block of the air outlet. At this time, the micro air pump inside the buffer duct draws in ambient air through the air inlet slot and sprays it out directionally through the air outlet, forming an airflow buffer layer opposite to the direction of pen tip movement. This airflow not only assists the cleaning component in removing residual dust from the screen, but also provides the user with resistance feedback that simulates paper writing through the reaction force, allowing the user to complete writing without excessive force, thereby reducing the risk of scratches on the screen surface caused by friction. In handwriting mode, after the user presses the power button, the infrared sensor dynamically adjusts the detection threshold by detecting changes in the distance between the button and the screen. After removing the sensing ring and wearing it on the finger, the system ensures that the triggering accuracy of finger writing and pen writing is consistent by recognizing the close-range signal of the sensing ring.

[0017] 3. In this solution, the side panel component resolves the conflict between ambient light interference and equipment stability. Infrared sensors on both sides of the side panel component monitor ambient light intensity in real time. When the lateral light intensity exceeds a preset threshold, the electric shaft is driven to rotate the light-blocking plate to the optimal angle, forming an oblique light-blocking barrier that effectively blocks strong lateral light and avoids display blurring caused by screen reflection. At the same time, the capacitive sensor accurately tracks the user's position through changes in the electric field, activating the cleaning component only when the user enters the writing area, reducing ineffective running time and lowering energy consumption. In terms of structural stability, the reinforcing bracket and connecting side block adopt an integrated aluminum alloy molding process to form a triangular stable structure that can withstand strong impact and resist the risk of collisions with people in the exhibition hall.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figures 1 to 8 An intelligent digital exhibition hall interactive display device and its usage method, comprising:

[0029] The intelligent display screen 1, as the core component of the entire interactive display device, possesses basic functions such as high-definition display and touch interaction. It can smoothly display various information, images, and video content, providing users with an intuitive and rich visual experience. Additional mechanisms are provided on both sides of the intelligent display screen 1. These additional mechanisms include a cleaning component, a writing component, and a side panel component. The cleaning component includes a top slide 24, which is securely mounted above the intelligent display screen 1. One side of the top slide 24 is tightly connected to the upper surface of the intelligent display screen 1 via a connecting strip. This connection method ensures the stability of the top slide 24 without interfering with the normal use of the intelligent display screen 1. The top slide 24 is positioned above the intelligent display screen 1. A connecting strip is provided on one side surface of the top slide 24, and the bottom surface of the connecting strip is connected to the upper surface of the smart display screen 1. A top baffle 2 is provided on one side surface of the top slide 24, and a connecting frame 26 is provided on one side surface of the bottom surface of the smart display screen 1. The connecting frame 26 serves as the supporting foundation for the bottom structure. A bottom baffle 3 is provided on one side surface of the connecting frame 26. The bottom baffle 3 has multiple functions. A load-bearing buffer plate 25 is provided on one side surface of the bottom baffle 3, providing a platform for placing the writing component. The writing component is placed on top of the load-bearing buffer plate 25. A fixing buckle 4 is also provided on one side surface of the bottom baffle 3 for securing the writing component. After the writing component is placed, it is firmly secured by the fixing buckle 4 to prevent the writing component from being accidentally placed. The bottom baffle 3, facing away from the supporting buffer plate 25, is equipped with a dust collection groove 27. During the cleaning process, some dust will naturally fall into the dust collection groove 27 for easy subsequent centralized cleaning. The intelligent display screen 1, facing away from the bottom baffle 3, is equipped with a sliding frame 9, which provides support and guidance for the entire sliding cleaning structure. An auxiliary sliding frame 10 is provided on one side of the sliding frame 9, which further enhances the stability and smoothness of the structure. The sliding frame 9 is equipped with a drive motor 11, which serves as a power source and provides strong and stable power for the entire cleaning process. The output end of the drive motor 11 is equipped with a threaded rod 12, and the surface of the threaded rod 12 is engaged with a meshing block 1. 5. A ventilation pipe 13 is provided on the upper surface of the meshing block 15. The upper end of the ventilation pipe 13 slides at the center of the top slide 24. An air outlet 14 is provided at the upper end of the ventilation pipe 13. The air outlet 14 can accurately spray airflow onto the surface of the smart display screen 1 to blow away the dust on the surface. The bottom end of one side of the ventilation pipe 13 is located inside the auxiliary slide 10. A slot is opened on the bottom surface of the auxiliary slide 10. The bottom end of the ventilation pipe 13 passes through the slot on the bottom surface of the auxiliary slide 10. A dust collection box 16 is provided at the bottom end of the ventilation pipe 13. A dust collection box 23 is provided on the bottom surface of the dust collection box 16. The interiors of the dust collection box 16 and the dust collection box 23 are connected to form a complete dust collection system. An air inlet 17 is provided on one side surface of the dust collection box 16.The air inlet 17 houses a small fan, and the dust collection box 16 contains a fine mesh screen 18. The fine mesh screen 18 effectively traps dust, preventing it from entering subsequent components and causing damage. Multiple connecting springs 21 are located on one side of the fine mesh screen 18, with one end connected to one side surface and the other side connected to the inner side surface. The dust collection box 16 contains a flip-up plate 22, with a torsion spring at the connection between the flip-up plate 22 and the dust collection box 16. A striking rod shaft 19 is also located on the inner side surface of the dust collection box 16, and multiple striking hammers 20 are mounted on its surface.

[0030] During use, the user writes and operates on the surface of the smart display screen 1 using the writing component. During writing, the device automatically cleans and vacuums dust using cleaning components on the top and bottom sides of the smart display screen 1. The device detects the user's position via the side panel components and automatically activates the cleaning components to clean one side of the writing area when the user uses the writing component. This prevents the writing component from pressing on dust that is statically attracted to the surface of the smart display screen 1, causing friction and scratches on the surface after prolonged use. The cleaning components are activated when the user removes the writing component from the upper surface of the support buffer plate 25. When removing the writing component, the user needs to lift the retaining clip 4. Lifting the clip 4 activates the touch button inside its slide. After activation, the infrared sensor 6 and capacitive proximity sensor 7 of the cleaning component begin to operate. The angle of the capacitive proximity sensor 7 remains fixed, while the infrared sensor 6, after locking onto the writing component held by the user, can adjust its angle via electric turntables at its upper and lower ends, ensuring it remains locked in position. When the user brings the writing component close to a certain distance, a writing operation is detected. At this point, the infrared sensor 6 uses its internal signal controller to control the drive motor 11, which in turn drives the threaded rod 12 to move... The device rotates, causing the ventilation duct 13 to slide inside the auxiliary slide 10 until it reaches the position of the corresponding writing component. During this time, the capacitive proximity sensor 7 continuously monitors the area. When the sensor detects the front end of the writing component, it determines that the writing component is approaching the smart display screen 1 in preparation for writing. At this point, a small fan inside the air inlet 17 draws in air, which is then forced through the ventilation duct 13 and expelled through the air outlet 14. This sprays air onto the pre-writing area of ​​the smart display screen 1, blowing away dust attracted by electrostatic charge and ensuring the writing area of ​​the screen remains clean. After the dust is blown away, it falls to the bottom of the smart display screen 1. The dust enters the air inlet 17 as the dust collection box 16 operates, eventually reaching the interior of the dust collection box 16. Once inside, the dust is intercepted by the fine mesh plate 18. As air passes through the fine mesh plate 18, it drives the striking rod shaft 19, causing multiple striking hammers 20 on its surface to rotate. Over time, dust accumulates on the surface of the fine mesh plate 18, increasing wind resistance and causing it to compress the connecting spring 21 and move to one side. When one side of the fine mesh plate 18 contacts the side of the striking rod shaft 19, the multiple striking hammers 20 on its surface strike that side, shaking off the dust layer.When the fine mesh plate 18 moves, the adhesion between the fine mesh plate 18 and the drive motor 11 disappears. Dust can fall through the opening between the fine mesh plate 18 and the flip plate 22 into the dust collection box 23 for storage. After a period of use, the dust collection box 23 can be disassembled and the dust inside can be cleaned.

[0031] The writing component is used for writing and operating on the surface of the smart display screen 1. The writing component includes a screen writing pen 5, which is the core of the writing component. One end of the screen writing pen 5 is provided with a handle, and the upper surface of the handle is provided with an activation button 28. One end of the activation button 28 is provided with a detachable sensor ring 29. The end of the screen writing pen 5 away from the handle is provided with a buffer air duct 30. One end of the buffer air duct 30 has multiple air inlet slots 31. These air inlet slots 31 are evenly distributed and can effectively draw in surrounding air. The other end of the buffer air duct 30 is provided with an air outlet 33 that communicates with the air inlet slots 31. The buffer air duct 30 is equipped with multiple miniature air pumps. The air inlet and air outlet of the miniature air pumps are respectively connected to the air inlet slots 31 and the air outlet 33. One end of the buffer duct 30 is provided with a sensor tube body 35. The surface of the sensor tube body 35 is provided with multiple shielding blocks 34. The interior of the air outlet 33 is provided with a miniature telescopic rod for driving the shielding blocks 34 to extend and retract. The upper surface of the sensor tube body 35 is also provided with a sensor groove. The interior of the sensor groove is provided with a sensor fan blade 36. The sensor fan blade 36 is made of lightweight and high-strength material and can rotate rapidly under the drive of airflow. There is an electrical connection between the sensor fan blade 36 and the miniature telescopic rod inside the sensor tube body 35. One side surface of the sensor tube body 35 is provided with a contact ball head 32. The contact ball head 32 is the part that directly contacts the screen writing pen 5 and the smart display screen 1. It is made of highly elastic and wear-resistant material, and the surface is specially treated to have good friction and conductivity.

[0032] The writing component assists the user in writing on the surface of the smart display screen 1, thereby achieving the effect of operating the smart display screen 1. During use, the user holds the screen writing pen 5 and writes on the surface of the smart display screen 1 through the contact ball head 32 at one end. While writing, as the contact ball head 32 gradually approaches the screen of the smart display screen 1, the sensing fan blades 36 inside the sensing slot at the center of the sensing tube 35 on its side surface begin to rotate due to the airflow from the air outlet 14. As the sensing fan blades 36 begin to rotate, a miniature telescopic rod inside the sensing tube 35 extends, pushing multiple blocking blocks 34 outwards and exposing multiple air outlets 33 on the side surface of the buffer air duct 30. At this time, the miniature air pump inside the buffer air duct 30 draws in air from the outside through the air inlet slot 31 and ejects it through the air outlets 33, allowing the airflow to directly spray onto the surface of the smart display screen 1. This, combined with the upper airflow of the cleaning component, achieves a better dust removal effect. When the wind blows onto the surface of the smart display screen 1, it generates a certain reaction force, providing the user with a stronger tactile feedback. This ensures that when the user writes on the surface of the smart display screen 1, the sufficient tactile feedback prevents excessive pressure during writing, thus protecting the smart display screen 1. When the user needs to write with their finger, they can press the power button 28 on the upper surface of the screen writing pen 5 to activate the handwriting mode. At this time, because the power button 28 is closer to the smart display screen 1 during handwriting than when writing normally with the screen writing pen 5, the distance detected by the infrared sensor 6 for the power button 28 will change. Subsequently, the user removes the sensing ring 29 from one end of the screen writing pen 5 and wears it on their finger. At this time, when the infrared sensor 6 detects the proximity of the sensing ring 29, it will trigger the detection function of the subsequent capacitive proximity sensor 7 at a closer distance than before, thus ensuring that the detection effect of handwriting is consistent with that of normal writing.

[0033] The side panel component includes: two connecting side blocks 37, which are made of high-strength, lightweight engineering plastic. The two connecting side blocks 37 are respectively located on the left and right sides of the smart display screen 1. A fixing connecting plate 8 is provided on one side surface of each of the two connecting side blocks 37. The fixing connecting plate 8 is made of metal, possessing high strength and stability. A reinforcing bracket 38 is provided on one side surface of the fixing connecting plate 8, and the reinforcing bracket 38 is connected to the top or bottom surface of the smart display screen 1. An electric shaft 40 is provided on both sides of each of the two connecting side blocks 37. The electric shaft 40 is a key component for enabling the light-blocking plate 39 to rotate flexibly. One side of the electric shaft 40... The surface is provided with a light-blocking plate 39, and one side surface of the two connecting side blocks 37 is respectively provided with an infrared sensor 6 and a capacitive proximity sensor 7. The infrared sensor 6 uses the physical properties of infrared light to measure. It can emit and receive infrared signals. By detecting the intensity and time difference of the reflected infrared signals, it can determine the distance and position of surrounding objects. The capacitive proximity sensor 7 works based on the principle of capacitance change. It can detect the approach of objects without contacting them. When the user's hand or other conductive objects approach the smart display screen 1, the capacitive proximity sensor 7 will detect the change in capacitance and transmit the signal to the control system.

[0034] The side panel component is used to fix the smart display screen 1 and to provide auxiliary effects during use. During installation, the user installs the smart display screen 1 on the wall using two fixed connecting plates 8. The infrared sensors 6 and capacitive proximity sensors 7 on the left and right sides of the side panel component are used to monitor the position of the writer in real time during use and to activate the cleaning component. When the infrared sensor 6 observes the position of the user, it can detect the ambient light and control the electric shafts 40 on the left and right sides to rotate according to the intensity of the light, so as to flip out the light blocking plate 39 to prevent the strong side light from affecting the observation effect of the smart display screen 1.

[0035] The working principle of this invention is:

[0036] When the user wants to perform a writing operation, the writing component—the screen writing pen 5—must be removed from the support buffer plate 25. When removing it, the fixing buckle 4 is lifted to activate the touch button in its slide. At this time, the infrared sensor 6 and the capacitive proximity sensor 7 of the cleaning component start to work. After the infrared sensor 6 locks the writing component, it adjusts the angle through the electric turntables at the upper and lower ends to continuously lock its position. When the writing component gets close to a certain distance, it is determined to be a writing operation. The infrared sensor 6 controls the drive motor 11 through the internal signal controller to drive the meshing threaded rod 12 to rotate, so that the ventilation pipe 13 slides in the auxiliary slide 10 to the corresponding writing component position.

[0037] The capacitive proximity sensor 7 continuously detects the writing component. When it detects the front end of the writing component, it determines that writing is about to begin. A small fan in the air inlet 17 draws in air, which is then sprayed out from the air outlet 14 through the ventilation pipe 13, blowing away the dust that is electrostatically attracted on the surface of the smart display screen 1, ensuring that the writing position is clean. The dust falls and enters the interior with the suction of the dust collection box 16, where it is intercepted by the fine mesh plate 18. The air passes through the fine mesh plate 18, which drives the striking rod shaft 19 and the striking hammer 20 to rotate. After long-term use, dust accumulates on the fine mesh plate 18, increasing the wind resistance. The compression connecting spring 21 moves and contacts the striking rod shaft 19. After contact, the striking hammer 20 strikes the fine mesh plate 18, shaking off the dust. The dust falls into the dust collection box 23 through the opening between the fine mesh plate 18 and the flip plate 22. The staff can periodically disassemble the dust collection box 23 to remove the dust.

[0038] When writing, the contact ball head 32 is brought close to the screen, the sensing fan blades 36 are rotated by the air outlet 14, the mini telescopic rod extends to expose the air outlet 33, the mini air pump draws in air and sprays it out, and the cleaning component removes dust, while providing contact feedback and protecting the screen. If you need to write with your finger, press the start button 28 to start the handwriting mode, remove the sensing ring 29 and wear it on your finger. The infrared sensor 6 triggers the capacitive proximity sensor 7 at a closer distance to detect the function, keeping the detection effect of handwriting and normal writing consistent.

[0039] The side panel component mounts the smart display screen 1 on the wall via a fixed connecting plate 8. The infrared sensor 6 and the capacitive proximity sensor 7 monitor the position of the writer in real time and activate the cleaning component. The infrared sensor 6 can also detect ambient light and control the electric shaft 40 to rotate the light-blocking plate 39 to prevent strong side light from affecting the observation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
