Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically a modular intelligent display screen. Background Technology

[0002] Display screens, which use semiconductor light-emitting diodes to display various information such as text, graphics, images, animations, and videos, are widely used in commercial advertising, school notices, and other fields.

[0003] Existing displays are exposed both when in use and when not in use, making it easy for dust to accumulate on the screen surface, which affects the user's visual experience. Currently, cleaning the screen requires manual wiping with towels or paper towels. Moreover, for some taller screens, it is difficult to clean the upper surface manually, which is not only laborious but also not very effective. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a modular intelligent display screen to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular intelligent display screen, including a base, a frame on the top of the base, a screen assembly on the outer surface of the frame, a winding box on the top of the frame, a servo motor on one side of the winding box, a drive shaft connected to the output end of the servo motor, a winding roller on the outer surface of the drive shaft, a dustproof cloth on the outer surface of the winding roller, a counterweight box connected to the bottom of the dustproof cloth, a sponge strip inside the counterweight box, a cushioning strip on the back of the dustproof cloth, and the drive shaft... One end is fixed with an active bevel gear, and a drive shaft is installed on the upper side of one side of the frame. The top and bottom ends of the drive shaft are respectively provided with a driven bevel gear and a drive gear. A liquid storage tank is provided on the lower side of one side of the frame, and a piston box is installed on the top of the liquid storage tank. A lead screw is installed on the top of the piston box, and a threaded seat is provided on the outer surface of the lead screw. A piston rod is fixed at the bottom of the threaded seat, and the bottom end of the piston rod extends into the interior of the piston box and fixes a piston block. One side of the piston box is connected to a counterweight box through an infusion tube, and a suction tube extending into the interior of the liquid storage tank is provided at the bottom of the piston box.

[0006] Furthermore, the screen assembly includes a first screen, a second screen, and a third screen.

[0007] By adopting the above technical solution, different video content can be played simultaneously through the combination of the first screen, the second screen, and the third screen.

[0008] Furthermore, a control panel is provided on the lower outer surface of the frame, and the servo motor, the first screen, the second screen and the third screen are all electrically connected to the control panel.

[0009] By adopting the above technical solution, users can control the servo motor, the first screen, the second screen and the third screen respectively through the control panel.

[0010] Furthermore, the outer surface of the frame is provided with sliding rods on both sides, and the counterweight box is provided with two sets of sliding sleeves, and the counterweight box slides with the sliding rods through the sliding sleeves.

[0011] By adopting the above technical solution, the counterweight box moves up and down more stably under the action of the slider and the sliding sleeve, and the sponge strip always adheres to the screen component, ensuring the cleaning effect.

[0012] Furthermore, the outer surface of the liquid storage tank is provided with an observation window, and a liquid filling port is provided on one side of the top of the liquid storage tank.

[0013] By adopting the above technical solution, users can check the liquid level inside the storage tank at any time through the observation window. When the cleaning fluid is insufficient, users can add cleaning fluid to the storage tank through the filling port.

[0014] Furthermore, guide rollers are installed on the outer surface of the winding box.

[0015] By adopting the above technical solution, the friction between the dustproof cloth and the buffer strip and the winding box is reduced under the action of the guide roller.

[0016] Furthermore, the driving bevel tooth meshes with the driven bevel tooth, the driving gear meshes with the driven gear, and the diameter of the driving bevel tooth is smaller than the diameter of the driven bevel tooth, and the diameter of the driving gear is smaller than the diameter of the driven gear.

[0017] By adopting the above technical solution, the rotation of the active bevel gear can drive the rotation of the driven bevel gear, and the rotation of the active gear can drive the rotation of the driven gear. Through the principle of the small gear driving the large gear, the speed reduction effect can be achieved. The purpose is to ensure that when the counterweight box is moved to the top or bottom, the piston block is located exactly above or below the inside of the piston block.

[0018] Furthermore, the buffer strip is provided in several groups, and the buffer strips are made of silicone material.

[0019] By adopting the above technical solution, several sets of silicone material buffer strips can play a certain buffering role when the screen is hit, which can effectively prevent damage to the screen components.

[0020] Furthermore, the infusion tube is a rubber hose, and both the infusion tube and the suction tube are equipped with one-way valves on their outer surfaces.

[0021] By adopting the above technical solution, the rubber hose has flexibility and extensibility, which allows the infusion tube to move in conjunction with the counterweight box.

[0022] Furthermore, the base has fixing holes on both sides of its top.

[0023] By adopting the above technical solution, the display screen can be installed on the ground through the fixing holes, making the display screen more stable.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model includes a servo motor, a winding box, a counterweight box, a drive shaft, a winding roller, a dustproof cloth, and a buffer strip. When the screen assembly is not in use, the user operates the servo motor to rotate, which in turn causes the drive shaft to rotate the winding roller. Under the gravity of the counterweight box, the dustproof cloth slowly moves downward, thus protecting the screen assembly from dust and effectively reducing dust accumulation on the screen assembly. Furthermore, when the screen is accidentally bumped, the buffer strip can cushion the impact force, thereby reducing the risk of damage to the screen assembly and improving the screen's lifespan.

[0026] 2. Based on the above-mentioned configuration, this utility model further includes a sponge strip, a driving bevel gear, a driven bevel gear, a driving gear, a driven gear, a piston rod, a piston box, a piston block, an infusion tube, a suction tube, and a lead screw. When the drive shaft drives the take-up roller to rotate and causes the counterweight box to move downward, the drive shaft can also drive the driving bevel gear to rotate, which in turn drives the driven bevel gear to rotate. This causes the transmission shaft to drive the driving gear to rotate, and the driving gear to drive the lead screw to rotate. Consequently, the threaded seat drives the piston block downward through the piston rod. During the downward movement of the piston block, the cleaning fluid in the piston box can be... The cleaning solution is delivered to the counterweight box via an infusion tube, where it is absorbed by a sponge strip. This allows the sponge strip to clean and remove dust from the screen components. When the counterweight reaches its maximum depth, the piston block also reaches the bottom of the piston box. When the screen needs to be used, the servo motor controls the drive shaft to rotate in the opposite direction, causing the counterweight to move upwards. As the piston block moves upwards, the suction tube draws the cleaning solution from the reservoir into the piston box for future cleaning. This design provides ideal cleaning results, a more thorough cleaning, and reduces the workload for users. Attached Figure Description

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1: A modular smart display screen, such as Figures 1-7As shown, the device includes a base 1, a frame 2 on top of the base 1, and a screen assembly 3 on the outer surface of the frame 2. The screen assembly 3 includes a first screen 301, a second screen 302, and a third screen 303. Different video content can be played simultaneously through the combination of the first screen 301, the second screen 302, and the third screen 303. A winding box 7 is located on the top of the frame 2. A guide roller 30 is installed on the outer surface of the winding box 7. Under the action of the guide roller 30, the friction between the dustproof cloth 18 and the buffer strip 19 and the winding box 7 is reduced. A servo motor 20 is located on one side of the winding box 7. The output end of the servo motor 20 is connected to a drive shaft 27. A winding roller 28 is located on the outer surface of the drive shaft 27. A dustproof cloth 18 is located on the outer surface of the winding roller 28. A counterweight box 6 is connected to the bottom of the dustproof cloth 18. A sponge strip 26 is located inside the counterweight box 6. A buffer strip 19 is located on the back of the dustproof cloth 18. A main... A driven bevel gear 29 is provided. A drive shaft 17 is mounted on the upper side of one side of the frame 2. The top and bottom ends of the drive shaft 17 are respectively provided with a driven bevel gear 21 and a drive gear 22. A liquid storage tank 10 is provided on the lower side of one side of the frame 2. An observation window 11 is provided on the outer surface of the liquid storage tank 10, and a liquid filling port 12 is provided on the top side of the liquid storage tank 10. Users can check the liquid level inside the liquid storage tank 10 at any time through the observation window 11. When the cleaning fluid is insufficient, users can add liquid to the liquid storage tank through the liquid filling port 12. The reservoir 10 is replenished with cleaning fluid, and a piston box 13 is installed on the top of the reservoir 10. A lead screw 15 is installed on the top of the piston box 13. A threaded seat 16 is provided on the outer surface of the lead screw 15. A piston rod 24 is fixed at the bottom of the threaded seat 16, and the bottom end of the piston rod 24 extends into the interior of the piston box 13 and fixes a piston block 25. One side of the piston box 13 is connected to the counterweight box 6 through an infusion tube 14. A suction tube 31 extending into the interior of the reservoir 10 is provided at the bottom of the piston box 13.

[0038] See Figure 1 In the above embodiment, a control panel 8 is provided below the outer surface of the frame 2, and the servo motor 20, the first screen 301, the second screen 302 and the third screen 303 are all electrically connected to the control panel 8. Users can control the servo motor 20, the first screen 301, the second screen 302 and the third screen 303 respectively through the control panel 8.

[0039] See Figures 1-4In the above embodiment, the active bevel tooth 29 meshes with the driven bevel tooth 21, and the active gear 22 meshes with the driven gear 23. The diameter of the active bevel tooth 29 is smaller than the diameter of the driven bevel tooth 21, and the diameter of the active gear 22 is smaller than the diameter of the driven gear 23. The rotation of the active bevel tooth 29 can drive the driven bevel tooth 21 to rotate, and the rotation of the active gear 22 can drive the driven gear 23 to rotate. By using the principle of a small gear driving a large gear, a speed reduction effect can be achieved. The purpose is to ensure that when the counterweight box 6 moves to the top or bottom, the piston block 25 is located exactly above or below the interior of the piston block 25.

[0040] See Figure 3 and Figure 6 In the above embodiment, the buffer strip 19 is provided in several groups, and the several groups of buffer strips 19 are made of silicone material. The several groups of silicone material buffer strips 19 can play a certain buffering effect when the screen is hit, which can effectively prevent the screen assembly 3 from being damaged.

[0041] See Figures 1-2 In the above embodiment, the infusion tube 14 is a rubber hose, and both the outer surfaces of the infusion tube 14 and the suction tube 31 are provided with one-way valves. The rubber hose is flexible and extensible, so that the infusion tube 14 can move in conjunction with the counterweight box 6.

[0042] See Figure 1 In the above embodiment, the base 1 has fixing holes 9 on both sides of its top, which allow the display screen to be installed on the ground, making the display screen more stable.

[0043] Example 2: To make the vertical movement of the counterweight box more stable, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 1 The frame 2 has sliding rods 4 on both sides of its outer surface, and the counterweight box 6 has two sets of sliding sleeves 5. The counterweight box 6 slides with the sliding rods 4 through the sliding sleeves 5. Under the action of the sliding rods 4 and the sliding sleeves 5, the counterweight box 6 moves up and down more stably, and the sponge strip 26 is always attached to the screen assembly 3, ensuring the cleaning effect.

[0044] The implementation principle of this utility model is as follows: When the screen assembly 3 is not in use, the user operates the servo motor 20 to rotate, thereby causing the drive shaft 27 to drive the take-up roller 28 to rotate. Under the gravity of the counterweight box 6, the dustproof cloth 18 slowly moves downward. Furthermore, when the drive shaft 27 drives the take-up roller 28 to rotate and causes the counterweight box 6 to move downward, the drive shaft 27 can also drive the active bevel gear 29 to rotate. The active bevel gear 29 drives the driven bevel gear 21 to rotate, thereby causing the transmission shaft 17 to drive the active gear 22 to rotate. The active gear 22 drives the lead screw 15 to rotate, which in turn causes the threaded seat 16 to drive the piston block 25 to move downward through the piston rod 24. During the downward movement of the piston block 25, the cleaning fluid in the piston box 13 can be delivered through the infusion tube. 14 is delivered to the counterweight box 6, and the sponge strip 26 absorbs the cleaning fluid, thereby enabling the sponge strip 26 to clean and remove dust from the screen assembly 3. When the counterweight moves to its maximum limit, the piston block 25 also moves to the bottom of the piston box 13. The dustproof cloth 18 can cover the screen assembly 3 to prevent dust, effectively reducing the amount of dust adhering to the screen assembly 3. When the screen is accidentally hit, the buffer strip 19 can cushion the impact force. When the screen needs to be used, the servo motor 20 controls the drive shaft 27 to rotate in the opposite direction, the counterweight moves upward, and the piston block 25 moves upward. During the movement, the suction pipe 31 can draw the cleaning fluid in the storage tank 10 into the piston box 13 for the next cleaning use.
