[0019] 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.

[0020] Please see Figures 1 to 4 This embodiment of a display screen with a protective film structure includes a screen 1, a protective film 2 attached to the front of the screen 1, and an extension block 3 connected to the back of the screen 1. The extension block 3 provides structural support and space expansion. Through its own extension design, it provides sufficient space for the brush plate 12 to be folded and stored behind the screen 1, avoiding interference with the screen 1 or other structures when the cleaning components are stored, and enhancing the integrity and stability of the back structure of the screen 1. An electric slide rail 4 is installed on the back of the extension block 3, providing linear drive power. It is slidably connected to a sliding block 5, and can drive the sliding block after activation. 5 moves smoothly laterally along the slide rail, providing basic power support for the cleaning action of the brush plate 12. A sliding block 5 is slidably connected to the electric slide rail 4. A first connecting block 6 is connected to the sliding block 5. A first electric push rod 7 is installed on the upper surface of the first connecting block 6. A second connecting block 8 is connected to the output end of the first electric push rod 7. A second electric push rod 9 is installed on the front of the second connecting block 8. A mounting block 10 is connected to the output end of the second electric push rod 9. A first motor 11 is installed on the front of the mounting block 10. The brush plate 12 is connected to the output end of the first motor 11. The back of the brush plate 12 is in contact with the front of the protective film 2.

[0021] The screen 1 is provided with a base 13 below it. A second motor 14 is installed on the base 13. The output end of the second motor 14 is connected to a support plate 15. The support plate 15 provides a support installation function. Its top surface is connected to a support block 22. The screen 1 is connected through the support block 22, support frame 23, and adjustment block 25, providing a stable support foundation for the overall structure of the screen 1, the back extension block 3, and the cleaning components.

[0022] The upper surface of the base 13 has a rotating groove 16, and a protective frame 17 is rotatably connected inside the rotating groove 16. The protective frame 17 provides protection and is fitted outside the second motor 14 to prevent dust, debris and other objects from entering the motor. It also prevents the human body from directly contacting the operating second motor 14, thus playing a role in safety protection and component protection, and enhancing rotational stability. Its bottom surface is rotatably connected to the rotating groove 16 of the base 13, and its top surface is fixed to the support plate 15 to form a vertical support structure. In conjunction with the rollers 21, it further restricts the shaking of the support plate 15 and ensures the stability of the screen 1 when it turns. The upper surface of the protective frame 17 is connected to the bottom surface of the support plate 15, and the protective frame 17 is set outside the second motor 14.

[0023] The base 13 has a circular groove 18 on its upper surface. The bottom surface of the support plate 15 is connected to two connecting rods 19. The bottom end of each connecting rod 19 is connected to a rotating frame 20. Each rotating frame 20 has a roller 21 rotatably connected to it via a pin. The outer surfaces of the two rollers 21 are in contact with the inner bottom wall of the circular groove 18. The rollers 21 reduce rotational friction. They are connected to the bottom surface of the support plate 15 through the rotating frame 20 and the connecting rods 19, and their outer surfaces are in contact with the inner bottom wall of the circular groove 18 of the base 13. This converts the sliding friction between the support plate 15 and the base 13 into rolling friction, reducing rotational resistance and improving support stability. The two rollers 21 are symmetrically distributed, providing balanced support for the support plate 15. Together with the protective frame 17, they limit the vertical displacement and swaying of the support plate 15 during rotation, ensuring the stability of the screen 1 when it turns.

[0024] The support plate 15 is connected to a support block 22, and the support block 22 is connected to a support frame 23. The support frame 23 is rotatably connected to a rotating shaft 24, and the outer surface of the rotating shaft 24 is connected to an adjusting block 25. The adjusting block 25 realizes the tilt angle adjustment of the screen 1. Its front is fixedly connected to the back of the screen 1, and its side is connected to the rotating shaft 24. It can rotate synchronously with the rotating shaft 24, driving the screen 1 to rotate around the rotating shaft 24 to meet different viewing angle requirements. Its structural design can provide a reliable installation and fixing point for the screen 1, enhance the firmness of the connection between the screen 1 and the support frame 23 and the rotating shaft 24, and prevent the screen 1 from loosening during angle adjustment or use. The front of the adjusting block 25 is connected to the back of the screen 1.

[0025] The support frame 23 has a fixed plate 26 connected to its side wall. A third motor 27 is mounted on the fixed plate 26. The output end of the third motor 27 is connected to the left end of the rotating shaft 24.

[0026] The extension block 3 is equipped with cooling fans 28 on both its upper and lower surfaces. These cooling fans 28 actively dissipate heat and cool the screen 1. When activated, they accelerate airflow around the screen 1, quickly removing the heat generated during operation and preventing localized overheating. This ensures a balanced temperature distribution. The dual cooling fans 28 are symmetrically arranged, creating a bidirectional airflow circulation that evenly dissipates heat from the back of the screen 1, preventing overheating and accelerated component aging, and extending the lifespan of the device. The base 13 is equipped with a controller 29 on its upper surface. The controller 29 coordinates the operation of the components, precisely controlling the start-up sequence, operating speed, and stopping time of each component. For example, during cleaning, it controls the movement of the electric slide rail 4 and the brush plate 12, and during turning, it synchronously coordinates the operation of the second motor 14 and the roller 21, ensuring smooth connection of all functions.

[0027] The working principle of the above embodiments is as follows:

[0028] When cleaning the protective film 2, the electric slide rail 4 is first activated by the controller 29. The electric slide rail 4 drives the sliding block 5 to move laterally, and then the brush plate 12 moves horizontally along the front of the screen 1 through the first connecting block 6, the second connecting block 8, and the mounting block 10. The brush plate 12 contacts the protective film 2 and wipes off the surface stains. When the brush plate 12 needs to be folded and stored after cleaning, the controller 29 first activates the first motor 11 to rotate the brush plate 12 90 degrees, then controls the second electric push rod 9 to retract and move the brush plate 12 backward. Finally, the first electric push rod 7 retracts and pulls the second connecting block 8 and the brush plate 12 downward, finally folding the brush plate 12 behind the screen 1. When the screen 1 needs to be turned, the controller 29 activates the second motor 14 on the base 13, whose output drives the brush plate 12 to rotate. The carrier plate 15 rotates, and the carrier plate 15 drives the screen 1 to rotate synchronously through the carrier block 22, support frame 23, and adjustment block 25, so as to realize the horizontal direction of the screen 1. During the rotation, the connecting rod 19 at the bottom of the carrier plate 15 drives the rotating frame 20 and roller 21 to roll in the circular groove 18 of the base 13. At the same time, the protective frame 17 rotates synchronously in the rotating groove 16 to provide support and protection for the carrier plate 15. When the angle of the screen 1 is adjusted, the third motor 27 on the fixed plate 26 is activated. Its output end drives the rotating shaft 24 to rotate in the support frame 23. The rotating shaft 24 drives the screen 1 to rotate around the rotating shaft 24 through the adjustment block 25, thereby adjusting the tilt angle of the screen 1 to adapt to different viewing needs. The cooling fan 28 can dissipate heat from the screen 1 to ensure stable operation of the equipment.

[0029] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
