[0002] Digital exhibition hall refers to a form of display that uses digital technology and network platforms to digitize the content of traditional physical exhibition halls and display them online. Digital exhibition halls can present rich exhibit information and interactive experiences through multimedia means such as virtual reality (VR), augmented reality (AR), panoramic display, video, audio, etc., allowing visitors to visit and learn online.

[0003] Among them, four-sided screen display cabinets are commonly used equipment in digital exhibition halls. After long-term use, a large amount of dust and impurities will adhere to the surface of the display screen, which will affect its surface clarity. Therefore, manual cleaning is required, which makes the use and maintenance of the display cabinet more troublesome. In addition, when the display screen is idle, it will be directly exposed to the external environment without effective protection. Dust is also easily adhered to its surface, which increases the workload of cleaning and maintenance.

[0004] Therefore, a display screen control device for a digital exhibition hall is proposed. Utility Model Content

[0027] like Figures 1 to 6 As shown, a display screen control device for a digital exhibition hall includes a fixed box 1 and a top plate 5. The inner wall of the fixed box 1 is slidably connected with a display box 2. The four sides of the display box 2, front, back, left, and right, are all fixedly installed with an interactive display screen 3. The bottom of the display box 2 is provided with a lifting control component 4 for controlling the up and down movement of the display box 2. The surface of the fixed box 1 is provided with a cleaning component 6 for cleaning the surface of the interactive display screen 3. The surface of the top plate 5 is provided with a dust collecting component 7. More specifically, through the operation of the interactive display screen 3, interactive display can be performed with users from multiple directions. When dust and impurities adhere to the surface of the interactive display screen 3, the cleaning component 6 is operated to wipe and clean the dust and impurities on the surface of the interactive display screen 3. The dust collecting component 7 is operated to absorb and process the wiped dust and impurities. When the device is idle, the lifting control component 4 is operated to control the display box 2 and the interactive display screen 3 to move downward until they enter the interior of the fixed box 1. Finally, the top plate 5 is pressed on the top surface of the fixed box 1. The fixed box 1 and the top plate 5 form a closed environment together to protect the interactive display screen 3.

[0028] The lifting control assembly 4 includes a mounting frame 401, and the mounting frame 401 is fixedly connected to the bottom surface of the display box 2. A first motor 402 is fixedly installed on the inner wall of the mounting frame 401. A rotating shaft 403 is fixedly connected to the output end of the first motor 402, and the end of the rotating shaft 403 is rotatably connected to the mounting frame 401. A driving gear 404 is fixedly sleeved on the surface of the rotating shaft 403. A mounting groove 405 is provided on the inner wall of the fixed box 1. A rack 406 is fixedly connected to the inner wall of the mounting groove 405, and the rack 406 is meshed with the driving gear 404. It should be noted that the first motor 402 is operated to drive the rotating shaft 403 and the driving gear 404 to rotate. Since the driving gear 404 is meshed with the rack 406, the driving gear 404 will move up and down under the action of the rack 406, thereby driving the rotating shaft 403 and the mounting frame 401 to rise and fall, thereby controlling the vertical movement of the display box 2.

[0029] The cleaning assembly 6 includes a second motor 601, and the second motor 601 is fixedly installed inside the front side wall of the fixed box 1. The output end of the second motor 601 is fixedly connected to a screw rod 602, the surface of the screw rod 602 is threadedly connected to a support frame 603, the top of the support frame 603 is fixedly connected to a mounting frame 604, and the inner wall of the mounting frame 604 is fixedly connected to a cleaning block 605. More specifically, the screw rod 602 is driven to rotate by the second motor 601, and the support frame 603 is driven to rise under the action of the surface thread, thereby pushing the mounting frame 604 to rise, and then driving the cleaning block 605 to slide along the surface of the interactive display screen 3, and the dust on the surface of the interactive display screen 3 is wiped and cleaned by the cleaning block 605.

[0030] The dust collection assembly 7 includes a dust collector 701, and the dust collector 701 is fixedly mounted on the top surface of the top plate 5, the suction end of the dust collector 701 is fixedly connected to a suction pipe 702, the end of the suction pipe 702 is fixedly connected to an air diffuser 703, a groove 704 is provided on the bottom surface of the top plate 5, and the air diffuser 703 is fixedly mounted on the inner wall of the groove 704. It should be noted that the dust and impurities pushed to the highest position by the cleaning block 605 will be sucked into the interior of the air diffuser 703 by the suction force generated by the operation of the dust collector 701, and then sent into the interior of the dust collector 701 through the suction pipe 702, thereby playing a dust collection role and preventing the cleaning assembly 6 from generating dust during the cleaning process.

[0031] There are two sets of driving gears 404 and racks 406, and the two sets of driving gears 404 and racks 406 are symmetrically distributed with the vertical center line of the front of the fixed box 1 as the symmetry axis. More specifically, by symmetrically arranging the two sets of driving gears 404 and racks 406, the bottom of the display box 2 is stably supported, making the display box 2 more stable during the lifting process.

[0032] Rollers 8 are provided at the four corners of the bottom of the fixed box 1, and the rollers 8 are universal wheels with a self-locking structure. It should be noted that by providing the rollers 8, it is convenient to carry and move the device, and by locking the rollers 8, the device can be placed more stably and not easy to shake.

[0033] In summary: through the operation of the interactive display screen 3, interactive display can be carried out with users from multiple directions. When dust and impurities adhere to the surface of the interactive display screen 3, the cleaning component 6 is operated to wipe and clean the dust and impurities on the surface of the interactive display screen 3, and the dust suction component 7 is operated to absorb and process the wiped dust and impurities. When the device is idle, the lifting control component 4 is operated to control the display box 2 and the interactive display screen 3 to move downward until they enter the interior of the fixed box 1. Finally, the top plate 5 is pressed against the top surface of the fixed box 1. The fixed box 1 and the top plate 5 together form a closed environment to protect the interactive display screen 3. During use, the effect of automatic cleaning of the exhibition hall display screen is achieved, and there is no need to arrange special personnel for cleaning and maintenance. The use and maintenance are more convenient, and the display screen can be stored and protected when it is idle to avoid dust adhesion or damage when idle.
