Description

Technical Field

[0001] This invention relates to the field of outdoor display technology, and more particularly to an outdoor display that facilitates module replacement. Background Technology

[0002] Outdoor displays are electronic display devices used in outdoor environments. They achieve high stability and reliability through super grayscale control technology, modular structure, and ultra-large-scale integrated circuit design. They mainly consist of dedicated computer equipment, a display screen, video input ports, and system software. They support real-time synchronous display, multi-standard signal input, and 3D animation playback. They feature high brightness, high resolution, strong environmental adaptability, and diverse functions, and are widely used in advertising, government publicity, and traffic information. With technological advancements and increasing market demand, the market prospects for outdoor displays are broad. A search revealed Chinese patent publication number 202211664037.5, which discloses an outdoor display device with easily replaceable modules, including an outdoor display frame and an outdoor display... The display screen body is fixedly installed at the front end of the screen frame. A closing device is provided at the rear end of the outdoor display screen frame. A screen refresh component is provided on the front surface of the outdoor display screen frame. The closing device includes a closing cover, a fixed support plate, a guide slide box, a guide slider, a height adjustment screw, a height adjustment sleeve, and a drive motor. A fixed support plate is provided on one side surface of the closing cover, and one end of the fixed support plate is fixedly installed at the side edge of the closing cover. A guide slide box is provided on one side surface of the outdoor display screen frame and is welded and fixed to the side of the outdoor display screen frame. A guide slider is provided on one side surface of the fixed support plate, and one end of the guide slider is fixedly installed on the inner surface of the fixed support plate. A height adjustment screw passes through the inside of the closing cover, and a height adjustment sleeve is fitted on the surface of the height adjustment screw. A drive motor is provided at the lower end of the height adjustment screw.

[0003] The aforementioned patent has the following shortcomings: When this device is in use, the screen cleaning component cannot independently wipe and clean the display screen. It can only clean the display screen body during the opening and closing of the closed cover. This makes the wiping and cleaning of the display screen body affected by the replacement cycle of the control module. As a result, it cannot wipe and clean the surface of the display screen during normal operation of the device. At the same time, when replacing the control module, the closed cover needs to be opened as a whole. It cannot be opened partially on one side, which means that the closed cover cannot be opened partially on one side when replacing the control module.

[0004] Therefore, there is an urgent need to improve an outdoor display screen that allows for easy module replacement in order to solve the aforementioned problems. Summary of the Invention

[0005] This invention provides an outdoor display screen that facilitates module replacement. The invention utilizes a combination of a single-sided rear cover independent operating structure and an independent screen cleaning structure to enable independent wiping and cleaning of the display screen. This allows for dust removal of the display screen even during the opening and closing of the sealed door, ensuring that wiping and cleaning of the display screen is unaffected by the control module replacement cycle. This allows for wiping and cleaning of the display screen surface during normal operation of the device. Furthermore, when replacing the control module, it is not necessary to completely open the closed cover; it can be partially opened on one side, allowing the sealed door to be partially opened on one side during control module replacement.

[0006] This invention provides an outdoor display screen with easily replaceable modules, comprising: A single-sided independent rear cover operating structure is slidably installed on the back of the support and fixing frame.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] like Figures 1-6As shown, an outdoor display screen with an easily replaceable module provided by an embodiment of the present invention includes: The independent operation structure 1 with a single rear cover can be slidably installed on the back of the support frame 2. The independent operation structure 1 with a single rear cover can be opened on one side of the support frame 2 for replacing and maintaining the control module 3 inside. Independent screen cleaning structure 4 is installed at the edge of the front face of the support frame 2. The display body 5 is installed on the front face of the support frame 2. The independent screen cleaning structure 4 is used to wipe and clean the outer surface of the display body 5. The support frame 2 facilitates the fixed support of the independent operation structure 1 with a single-sided back cover, the independent screen refresh structure 4, and the control module 3. The control module 3 here refers to the existing structural module, and the display body 5 is also an existing module, so its working principle is the existing technology, so it will not be described in detail here. The main function of the control module 3 is to cooperate with the display body 5 to carry out the operation. The independent operation structure 1 and the independent screen cleaning structure 4 work together to enable the display screen to be wiped and cleaned independently. This allows the display screen to be cleaned even when the sealed door is not being opened or closed, and the wiping and cleaning of the display screen is not affected by the replacement cycle of the control module. This allows the display screen surface to be wiped and cleaned during normal operation of the device. At the same time, when replacing the control module, it is not necessary to open the closed cover as a whole. It can be opened partially on one side, and the sealed door can be opened partially on one side when replacing the control module.

[0023] Furthermore, such as Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the independent operation structure 1 with a single rear cover includes two sealing doors 6 and a drive assembly 7. The drive assembly 7 is used to drive the two sealing doors 6 to move relative to each other. The supporting and fixing frame 2 is provided with a receiving cavity 8. The two side walls of the receiving cavity 8 are symmetrically provided with sliding track cavities 9 suitable for the sealing sliding of the sealing doors 6. The opposite ends of the two sealing doors 6 are respectively provided with sealing protrusions 10 and sealing grooves 11. The sealing protrusions 10 and sealing grooves 11 are mutually engaged. The two sealing doors 6 can be partially separated to close the rear opening of the receiving cavity 8. The drive assembly 7 can provide driving force for opening and closing the sealing doors 6. The receiving cavity 8 can accommodate several control modules 3. The sliding track cavity 9 can provide a limiting receiving cavity for the sealing doors 6. The sealing protrusions 10 and sealing grooves 11 cooperate with each other to improve the sealing performance of the opposite ends of the two sealing doors 6.

[0024] Furthermore, such as Figure 3 , Figure 4 as well as Figure 5As shown, the sliding track cavity 9 includes a sliding cavity groove 12 and limiting grooves 13 symmetrically opened on the upper and lower end faces of the inner wall of the sliding cavity groove 12. Limiting sliders 14 are provided on both the upper and lower end faces of the sealing door 6. The limiting sliders 14 and the limiting grooves 13 slide in contact with each other. The sliding cavity groove 12 can easily accommodate the sealing door 6. The limiting grooves 13 and the limiting sliders 14 cooperate with each other to make the sealing door 6 be limited and embedded in the sliding track cavity 9.

[0025] Furthermore, such as Figure 4 As shown, the drive assembly 7 includes a dual-axis motor 15 embedded in the side wall of the receiving cavity 8, a drive gear 16 installed at the output end of the dual-axis motor 15, and several linkage grooves 17 formed inside the sealing door 6 and meshing with the drive gear 16. Several cross-shaped limiting grooves 18 are provided at the bottom of the dual-axis motor 15, and cross-shaped limiting blocks 19 are provided on the side wall of the receiving cavity 8 and interlocking with the cross-shaped limiting grooves 18. The dual-axis motor 15 provides driving force to the drive gear 16. The drive gear 16 and the several linkage grooves 17 cooperate with each other to enable the dual-axis motor 15 to drive the sealing door 6 to open and close when it is working. The cross-shaped limiting grooves 18 and the cross-shaped limiting blocks 19 cooperate with each other to enable the dual-axis motor 15 to be embedded in the side wall of the receiving cavity 8.

[0026] Furthermore, such as Figure 4 As shown, a mounting block 20 is provided at the output end of the dual-axis motor 15. The drive gear 16 is mounted on the mounting block 20 by bolts. Several weight-reducing slots 21 are evenly spaced on the drive gear 16. A mounting bracket 22 is provided in the receiving cavity 8. Several control modules 3 are embedded and mounted on the mounting bracket 22. The mounting block 20 facilitates the mounting of the drive gear 16 on the output shaft end of the dual-axis motor 15 by bolts. The weight-reducing slots 21 help to reduce the workload of the dual-axis motor 15. The mounting bracket 22 facilitates the support and fixation of several control modules 3.

[0027] Furthermore, such as Figure 2 and Figure 5As shown, the independent screen refresh structure 4 includes electric guide rails 23 installed on both sides of the front end of the support frame 2, a support mounting rod 24 disposed between the movable seats in the two electric guide rails 23, a flexible cleaning brush block 25 installed on the support mounting rod 24, a protective enclosure 26 disposed around the electric guide rails 23, and a sealing cover 27 installed at the upper opening of the protective enclosure 26. The two electric guide rails 23 facilitate the driving force for the up-and-down reciprocating movement of the support mounting rod 24. Here, the electric guide rails 23 are existing structures, so the working principle of the electric guide rails 23 is existing technology, and therefore will not be described in detail here. The support mounting rod 24 facilitates the support and fixation of the flexible cleaning brush block 25, and the flexible cleaning brush block 25 facilitates the wiping and cleaning of the surface of the display body 5. The protective enclosure 26 and the sealing cover 27 facilitate the protection of the drive unit of the independent screen refresh structure 4.

[0028] Furthermore, such as Figure 5 As shown, the display body 5 is snapped into the front mounting frame 28, which is bolted onto the support frame 2. Several polygonal snap-fit ​​slots 29 are distributed through the front mounting frame 28, and polygonal snap-fit ​​blocks 30 are provided on the support frame 2 to fit into the polygonal snap-fit ​​slots 29. The front mounting frame 28 facilitates the fixing of the display body 5 onto the support frame 2, and the polygonal snap-fit ​​slots 29 and polygonal snap-fit ​​blocks 30 cooperate to allow the front mounting frame 28 to be snapped into the support frame 2.

[0029] Furthermore, such as Figure 1 , Figure 3 as well as Figure 4 As shown, an anti-slip strip 31 is provided on the inner side of the sealing door 6 away from the drive assembly 7. Scraping assemblies 32 are provided on both sides of the receiving cavity 8 near the outer side of the sealing door 6. A support mounting bracket 33 is provided on the lower end face of the support and fixing frame 2. The anti-slip strip 31 prevents the sealing door 6 from slipping off the end of the sliding track cavity 9 when it is opened. The scraping assembly 32 facilitates wiping the outer surface of the sealing door 6. The support mounting bracket 33 facilitates fixing the device in a designated location.

[0030] Furthermore, such as Figure 3 As shown, the scraping assembly 32 includes a scraping cleaning block 34 and a drain outlet 35 located on the support frame 2 and directly below the side of the scraping cleaning block 34. The scraping cleaning block 34 is installed on the support frame 2 by bolts. The scraping cleaning block 34 facilitates wiping the floating dust on the outer surface of the sealing door 6, and the drain outlet 35 facilitates the rapid flow of rainwater that has been scraped off.

[0031] Furthermore, such as Figure 6As shown, the support mounting frame 33 includes support fixing columns 36 symmetrically arranged on the lower end face of the support fixing frame 2, mounting fixing plate 37 arranged at the end of the support fixing column 36, and a plurality of bolt fixing holes 38 evenly spaced and drilled through the mounting fixing plate 37. The support fixing column 36 facilitates raising the device and supports the device. The mounting fixing plate 37 and the bolt fixing holes 38 cooperate with each other to facilitate the installation of the device in a designated location.

[0032] In this embodiment, as Figures 1-6 As shown, the working principle and usage process of this invention are as follows: S1. When using this device, it should first be moved to the required location, and then the device should be installed at the required location using fixing bolts. Subsequently, the display screen body 5 and several control modules 3 required should be installed on the mounting bracket 22. At this time, an overall control module of the device should be installed in the mounting bracket 22. The working principle of this module is existing technology, which will not be elaborated here. The purpose of this module is to facilitate connection to the control terminal computer, so that the device can be controlled to operate normally through the control terminal computer. S2. When the device needs to wipe and clean the outer surface of the display screen body 5, the control terminal computer will issue a work command to the independent screen-wiping structure 4. At this time, the moving seats on the two electric guide rails 23 will move up and down synchronously. Then, the support mounting rod 24 will start to move up and down under the action of the moving seats on the two electric guide rails 23. At this time, the flexible cleaning brush block 25, which is bolted to the support mounting rod 24, will wipe and clean the outer surface of the display screen body 5. Because the independent screen-wiping structure 4 is not synchronized with the independent operation structure 1 with the single-sided rear cover, the wiping and cleaning of the display screen body 5 is not controlled by the control module. The replacement cycle allows the device to wipe and clean the surface of the display screen body 5 during normal operation. After the surface of the display screen body 5 is wiped and cleaned, the control terminal computer will issue a stop operation command to the independent screen refresh structure 4. At this time, the moving seats on the two electric guide rails 23 will return to the initial state with the support mounting rod 24 on which the flexible cleaning brush block 25 is installed. In order to ensure the synchronous movement of the moving seats on the two electric guide rails 23, a synchronization controller is installed between the two electric guide rails 23. This synchronization controller is an existing module, so its working principle is also existing technology, which will not be elaborated here. S3. When the device needs to replace the control module 3, it should first be determined whether the control module 3 is on the left or right side of the mounting bracket 22. Then, the control terminal computer should be selected to control the opening of the corresponding sealing door 6 according to the bias. At the same time, the two sealing doors 6 can be opened through the control terminal computer as needed. S4. When it is necessary to open one side of the sealing door 6, the control terminal computer needs to issue a work command to the dual-axis motor 15 on that side. Then, the output shaft of the dual-axis motor 15 will drive the drive gear 16 to rotate. At this time, under the action of the drive gear 16 and several linkage grooves 17, the sealing door 6 on this side will slowly open. When the operator observes that the sealing door 6 has been opened to a suitable extent, the operator will issue a stop work command to the dual-axis motor 15 on that side through the control terminal computer. At this time, the sealing door 6 will no longer move. Then, the operator will take out the replacement control module 3 to be replaced and then install the replacement control module 3 to be installed. The installation can be completed by placing the mounting bracket 22 on the platform. Once the installation is complete, the operator will issue a work command to the dual-axis motor 15 on this side via the control terminal computer. At this time, the output shaft of the dual-axis motor 15 will drive the drive gear 16 to rotate in the opposite direction. The sealing door 6 on this side will then slowly close. After the operator observes that the sealing door 6 on this side is completely closed, the operator will issue a stop work command to the dual-axis motor 15 on this side via the control terminal computer. Then the sealing door 6 on this side will stop moving. If it is necessary to open the sealing door 6 on the other side, the steps are the same as above. At the same time, the sealing doors 6 on both sides can be opened together by following the above steps.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
