Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1 - Figure 9The multi-module combined billboard shown includes a screen mounting box 10, a screen mounting plate 29 inside the screen mounting box 10, multiple display screens 11 mounted on the screen mounting plate 29, and a protective device outside the screen mounting box 10. The protective device includes a top storage box 1 at the top of the screen mounting box 10 and a bottom storage box 2 at the bottom of the screen mounting box 10. A winding roller 14 is installed inside the top storage box 1, and a protective cloth 4 for protecting the multiple display screens 11 is wound around the outside of the winding roller 14. Steel wires 19 are installed at both ends of the extended end of the protective cloth 4. A winding device 131 for winding the steel wires 19 is installed inside the bottom storage box 2.

[0029] The winding device 131 includes a bearing seat 20, a winding shaft 18 is provided on one side of the bearing seat 20, the extension end of the steel wire 19 is fixed to the outside of the winding shaft 18, a second motor 17 is also provided on one side of the bearing seat 20, an installation cavity 13 is opened inside the bottom storage box 2, the winding device 131 is located in the installation cavity 13, and a base 3 is also provided at the bottom of the bottom storage box 2; in specific implementation, starting the output shaft of the second motor 17 will drive the winding shaft 18 to rotate, and the winding shaft 18 will wind the steel wire 19 during rotation, thereby achieving the purpose of pulling the protective cloth 4;

[0030] Both ends of the top storage box 1 are provided with protective covers 8. Inside the protective cover 8, there is a support block 12. The top of the support block 12 is provided with a first motor 15. The output shaft end of the first motor 15 is connected to the end of the take-up roller 14. Inside the top storage box 1, there is a guide roller 16. The protective cloth 4 can extend downward after passing through the guide roller 16. The protective cloth 4 and the take-up roller 14 form a protective assembly.

[0031] The bottom of the top storage box 1 has a rectangular opening through which the protective cloth 4 can move downward. During the release of the protective cloth 4, the first motor 15 is started. The output shaft of the first motor 15 drives the winding roller 14 to rotate, and the winding roller 14 begins to release the protective cloth 4. At the same time, the second motor 17 is started. The output shaft of the second motor 17 drives the winding shaft 18 to rotate and wind the steel wire 19. The steel wire 19 pulls both ends of the protective cloth 4 downward. The protective cloth 4 will not fold during the movement and will not cause friction to the display screen 11. The protective cloth 4 moves downward until it covers the front surface of the screen mounting box 10 and protects the display screen 11.

[0032] like Figure 8 and Figure 9As shown, an airbag 27 is provided inside the screen mounting box 10 on the rear surface of the screen mounting plate 29. A mounting base 9 is provided at the rear of the screen mounting box 10. A groove 25 is opened on the front surface of the mounting base 9, and a first air pump 21 and a second air pump 22 are provided in the groove 25. Gas pipes 23 are provided at the output ends of the first air pump 21 and the second air pump 22. The extended end of the gas pipe 23 is connected to the airbag 27. The gas pipe 23 is also connected to a solenoid valve 24. A spring 28 is provided on the rear surface of the screen mounting plate 29, and a rear cover 26 is provided on the rear surface of the screen mounting box 10. The extended end of the spring 28 is fixedly connected to the rear cover 26. The mounting base 9 and the screen mounting box 10 form a support device. The internal structure of the screen mounting box 10 is a support component for supporting the display screen 11.

[0033] Specifically, when there is no gas inside the airbag 27, the spring 28 is in its original state. During the inflation process inside the airbag 27, the airbag 27 begins to expand, and the screen mounting plate 29 moves forward towards the screen mounting box 10 due to the thrust of the airbag 27. At the same time, the display screen 11 also moves forward towards the screen mounting box 10 until the front surface of the display screen 11 is level with the front end of the screen mounting box 10. Inflation into the airbag 27 stops, and the passage of the solenoid valve 24 is closed. The gas inside the airbag 27 will not be released. The airbag 27 continues to support the screen mounting plate 29 and the display screen 11, thereby keeping the display screen 11 static.

[0034] After the protective cloth 4 is placed in front of the screen mounting box 10, because the protective cloth 4 is a soft structure, even if it is stretched, external objects touching the surface of the protective cloth 4 will cause the protective cloth 4 to deform inward towards the screen mounting box 10. This deformation is not obvious, but it will touch the surface of the display screen 11. In order to solve this problem, in this application, the first air pump 21 and the second air pump 22 are used to extract the gas inside the airbag 27. The airbag 27 is deflated, and the spring 28 has a tendency to return to its original shape and slowly shortens. During the shortening process, the screen mounting plate 29 moves the display screen 11 a certain distance behind the screen mounting box 10 so that there is a safe distance between the display screen 11 and the protective cloth 4, so that external objects, such as hail, branches and other impurities, will not hit the display screen 11, thereby achieving the purpose of protecting the display screen 11.

[0035] like Figure 1As shown, a solar panel 6 is installed on the top of the top storage box 1. A wiring conduit 7 is installed on one side of the solar panel 6, and an energy storage device 5 is installed at one end of the wiring conduit 7. The solar panel 6 and the energy storage device 5 constitute a power supply device. The energy storage device 5 is equipped with a controller, which is an intelligent programmable controller used to control the operation of the electrical equipment in this application. The combined billboard of this application should be installed outdoors in specific use. It absorbs solar energy through the solar panel 6 to generate electricity and stores it in the energy storage device 5. The solar power generation and energy storage technologies and principles have been maturely applied in the prior art and will not be elaborated here. After storing electricity, the energy storage device 5 can be used as a power source to provide power to the controller, display screen 11, solenoid valve 24, first motor 15 and second motor 17 of this application to ensure normal operation.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
