Description

Technical Field

[0001] This invention relates to the field of LED information board technology, specifically to a wind-resistant LED information board that is easy to assemble and disassemble. Background Technology

[0002] With economic development, the mileage and scale of expressways are constantly increasing, and the level of intelligence of expressways is also getting higher and higher. The application of full-color LED information boards in highways, bridges, waterways and other fields has become commonplace. Since full-color LED information boards usually have a large display area, and there are strong winds in open areas such as expressways and bridges, as well as long gantry spans and certain load-bearing limitations, most of the current products on the market are lightweight, thin, wind-resistant full-color LED information boards. The information board display modules can be independently disassembled and installed at the front and back. This design means that during maintenance, there is no need to disassemble the entire information board on a large scale. Only the display module with the problem needs to be operated, which greatly improves the convenience and efficiency of maintenance.

[0003] In the prior art, such as the wind-resistant and energy-saving LED information board disclosed in CN213366013U, an information board is fixedly installed on the front of the box; the left and right side walls of the box are evenly spaced and machined with connecting holes; a control box is fixedly installed in the center of the box; a positioning plate is symmetrically fixedly installed on the bottom and top surfaces of the box; an electric telescopic rod is horizontally fixedly installed on the outer side wall of the positioning plate; a push plate is vertically fixedly installed at the front end of the electric telescopic rod; connecting blocks are evenly spaced and machined on the outer side wall of the push plate; water pumps are symmetrically fixedly installed on the left and right sides of the bottom surface of the box; a water suction pipe is connected to the water suction end of the water pump; a water suction plate is fixedly connected to the water inlet end of the water suction pipe; and water suction holes are evenly spaced and machined on the lower outer side wall of the water suction plate. To address the issues of poor wind resistance, heat dissipation, and water drainage capabilities of existing information boards, the aforementioned document proposes a solution using a combination of water-absorbing trays and cooling fans. However, in practical use, it is not possible to easily disassemble and assemble the independent display modules. Furthermore, the traditional display modules and frame have insufficient support strength and a simple structure. Under strong winds, the modules are easily subjected to wind pressure and stretching, resulting in deformation. This affects the display quality and the overall structural stability of the information board, impacting not only the flatness of the information board's appearance but also potentially causing damage to the internal display modules and electrical components due to pressure or stretching. Moreover, traditional display modules are not easy to disassemble and maintain.

[0004] Therefore, this invention proposes a wind-resistant LED information board that is easy to assemble and disassemble, in order to solve the problems of insufficient support strength and simple structure of existing display modules, which are easily squeezed and deformed under strong winds, thus affecting display quality, and are inconvenient to assemble and disassemble.

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figures 1-19This invention provides a technical solution: a wind-resistant LED information board that is easy to assemble and disassemble, comprising an information board mounting frame 1, a square hole 10 on the information board mounting frame 1, and an LED display module 2 movably mounted inside the square hole 10. The LED display module 2 consists of a lamp body mounting back plate 21, a central connecting plate 22, an LED display panel 23, and a light-transmitting panel 24. Circular air vents are correspondingly provided on the inner walls of the LED display panel 23 and the light-transmitting panel 24. LED beads are evenly distributed on the LED display panel 23, and LED bead slots are provided on the inner wall of the light-transmitting panel 24. Air can pass through the evenly distributed circular air vents, through the hollowed-out inner support plate 25, and through the hollowed-out back side of the lamp body mounting back plate 21 to form natural convection, avoiding heat accumulation between the screens and thus affecting the display effect; the inner wall of the back side of the lamp body mounting back plate 21 is provided with... A reserved slot 210 is provided, and an active air guiding unit is provided on the inner side of the reserved slot 210. An inner support unit center connecting plate 22 is provided between the lamp body mounting back plate 21 and the LED display panel 23 and is fixedly installed in the center of the lamp body mounting back plate 21. An active cavity is opened on the inner surface of the center connecting plate 22, and a locking member is provided on the inner side wall of the active cavity. A docking groove 2200 and an unlocking member mounting groove 2220 that communicate with the active cavity are respectively opened on the inner wall of the center connecting plate 22 away from the LED display panel 23. An inner snap-fit ​​member is movably installed on the inner side of the docking groove 2200, and an unlocking member is provided on the inner side of the unlocking member mounting groove 2220. The inner snap-fit ​​member includes a snap-fit ​​block 231, and the snap-fit ​​block 231 is fixedly installed on the inner surface of the LED display panel 23. The outer surface of the snap-fit ​​block 231 away from the LED display panel 23 is movably snapped with the inner surface of the docking groove 2200. In this embodiment, through optimized design of the LED display module 2 structure, the LED display module 2 adopts a multi-layer structure design, and an inner support plate 25 with a hollowed-out pattern is added to the inner side. While ensuring structural stability, it reduces the weight of the module, facilitates disassembly and transportation, and allows air to flow smoothly between the screens, effectively reducing wind resistance and minimizing the impact of wind on the information board. Furthermore, through the cooperation of internal connectors, locking components, and unlocking components, convenient and independent disassembly and maintenance of the LED display panel 23 and the light-transmitting panel 24 with the central connecting plate 22 are achieved. In addition, by combining the active air guiding unit with the inner support plate 25, active and passive heat dissipation of the internal structure of the display module is realized, effectively reducing wind resistance and further increasing the overall service life of the LED display module.

[0021] Example 2, see attached document Figures 1-19 Based on Example 1, in order to ensure the overall structural strength of the LED display module while satisfying air convection between the screens and achieving natural heat dissipation: The back surface of the lamp body mounting back plate 21 is movably engaged with the inner surface of the square hole 10, and the lamp body mounting back plate 21 is fixedly connected to the information board mounting frame 1 by bolts. The back surface of the lamp body mounting back plate 21 has evenly spaced perforated grooves, and limit posts 211 are fixedly installed on the inner surface of the lamp body mounting back plate 21. The inner support unit includes an inner support plate 25, which consists of an outer support frame, an inner support frame 251, and a reinforcing side plate 252. Limit holes 2510 are evenly spaced on the inner wall of the inner support frame 251, and the inner surface of the limit holes 2510 is engaged with the outer surface of the limit posts 211. The reinforcing side plate 252 is movably fitted into one side of the outer support frame, and the reinforcing side plate 252 is fixedly installed on both sides of the central connecting plate 22. The outer ring surface of the outer support frame is provided with an air guide groove 250, the inner wall of one side of the air guide groove 250 is provided with a connecting groove 2500, and the inner walls of both sides of the air guide groove 250 are provided with a through side ring hole 2501. The inner walls of both ends of the reinforcing side plate 252 are respectively provided with air guide round holes 2520, and the inner walls of both ends of the central connecting plate 22 are respectively provided with mating round holes 220 corresponding to the air guide round holes 2520. In this embodiment, refer to Figure 7 , Figure 8 and Figure 12 As shown, an inner support plate 25 is added between the lamp mounting back plate 21 and the LED display panel 23 to increase the overall structural strength. The inner support plate 25 is guided and limited by the corresponding fit of the limiting post 211 and the limiting hole 2510, ensuring stable positioning of the inner support plate 25 on the lamp mounting back plate 21. The hollow design of the inner support plate 25 reduces the overall weight of the display module support structure without affecting natural airflow. Air enters between the lamp mounting back plate 21 and the LED display panel 23 through evenly spaced circular vents on the LED display panel 23 and the light-transmitting panel 24, and flows through the hollow groove on the back side of the lamp mounting back plate 21, further reducing wind resistance. It should also be noted that, referring to… Figure 10 , Figure 11 As shown, side ring holes 2501 are opened on the sides of the inner support plate 25 and the outer support frame. With this design, some air is guided along the side ring holes 2501 on both sides and flows along the path of the air guide groove 250 opened on the outer periphery of the outer support frame, so as to realize the heat dissipation of the outer periphery of the inner support plate 25. It is worth noting that the inner walls of the reinforced side plate 252 and the central connecting plate 22 are respectively provided with air guide round holes 2520 and docking round holes 220, which will not affect the natural flow of air.

[0022] Example 3, refer to Appendix Figures 1-19 Based on Embodiment 2, in order to achieve passive heat dissipation between the screens: A working box 11 is fixedly installed on the side of the information board mounting frame 1 away from the LED display module 2. A box cover 12 is hinged to the outer surface of the working box 11. An active air guiding unit is set inside the working box 11. The active air guiding unit includes a main air duct 13, a branch air duct 14 and a fan 15. The fan 15 is fixedly installed on the lower outer surface of the main air duct 13. The air inlet end of the branch air duct 14 is connected to the inner wall of the main air duct 13, and the air outlet end of the branch air duct 14 is sealed to the inner wall of the reserved groove 210. A duct groove 100 is opened on the inner wall of the information board mounting frame 1. The inner surface of the duct groove 100 is movably engaged with the outer surface of the branch air duct 14. In this embodiment, refer to Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in hot, windless weather, the heat between the display module screens is difficult to dissipate on its own. By turning on the fan 15, the airflow is guided through multiple sets of branch ducts 14 to the inside of the lamp mounting backplate 21, specifically as follows: Figure 10 As shown, the airflow is introduced through the connecting groove 2500 and the side ring hole 2501, flows along the path of the air guide groove 250 distributed on the outer periphery of the outer support frame, and then is discharged through the hollow groove on the back side of the lamp body mounting back plate 21 and the evenly distributed circular air holes on the LED display panel 23 and the light-transmitting panel 24. This achieves passive heat dissipation from the inside of the lamp body mounting back plate 21 and the LED display panel 23, further avoiding heat accumulation in the display module and extending the overall service life of the equipment.

[0023] Example 4, see attached document Figures 1-19 Based on Embodiment 3, in order to achieve quick and convenient assembly and disassembly between the independent LED display panel 23 and the light-transmitting panel 24 and the lamp mounting back plate 21: The locking mechanism includes a fixed hook 221, which is fixedly installed on the side wall of the movable cavity away from the LED display panel 23. A rubber sleeve 2311 is fitted onto the outer surface of the end of the locking block 231 away from the LED display panel 23, and the outer surface of the rubber sleeve 2311 is movably fitted into the inner surface of the mating groove 2200. An installation groove 2310 is provided on the inner wall of the locking block 231, and a swing hook 232 is rotatably connected to the inner surface of the installation groove 2310 via a pin. The swing hooks 232 are mirror-distributed about the central axis of the locking block 231. Two sets of swing hooks 232... An elastic flap 233 is fixedly connected between the inner sides, and the outer surfaces of the two sets of elastic flaps 233 are movably engaged with the inner surface of the fixed hook 221; the unlocking component includes a force plate 222, which has an "L"-shaped plate structure. The inner surface of the force plate 222 is movably abutted against the outer surface of the swing hook 232. The force plate 222 is slidably installed on the inner surface of the unlocking component mounting groove 2220, and a force-bearing spring block 2221 is fixedly connected to the inner surface of the force plate 222. The other end of the force-bearing spring block 2221 is fixedly connected to the inner side wall of the unlocking component mounting groove 2220. In this embodiment, when installing the independent LED display panel 23 and the light-transmitting panel 24 with the lamp mounting back plate 21, the corresponding LED beads of the LED display panel 23 and the light-transmitting panel 24 are matched and installed. The assembled whole is pushed towards one side of the lamp mounting back plate 21. At this time, the two sides of the LED display panel 23 are respectively embedded into the inner side of the lamp mounting back plate 21. When the LED display panel 23 and the light-transmitting panel 24 are pushed forward, refer to... Figure 14 , Figure 15 and Figure 17 As shown, the snap-fit ​​block 231 connected to the inner side of the LED display panel 23 enters from the front side of the central connecting plate 22 and continues to advance until the rubber sleeve 2311 is snapped into the docking groove 2200, achieving the initial positioning of the LED display panel 23. At this time, the two sets of swing hooks 232 installed inside the mounting groove 2310 are pressed inward by the fixed hooks 221, and the elastic flap 233 is elastically compressed by the pressure from both sides. After the snap-fit ​​block 231 is fully snapped into the docking groove 2200, the swing hooks 232 also automatically snap into the fixed hooks 221 inside the central connecting plate 22. In this way, the quick snap-fit ​​between the individual LED display panel 23 and the light-transmitting panel 24 and the lamp mounting back plate 21 is achieved. Only inward pushing is required, without additional tools. When it is necessary to disassemble and maintain the independent LED display panel 23 and the light-transmitting panel 24, refer to Figure 15As shown, the operator presses the force plate 222 on the back of the lamp mounting back plate 21 simultaneously. At this time, the force plate 222 squeezes the swing hook 232 on the inside, and the elastic flap 233 is compressed. Under this step, the fixed hook 221 releases the restriction on the swing hook 232. The operator can then pull the LED display panel 23 and the light-transmitting panel 24 away from the lamp mounting back plate 21. Then, the force plate 222 is released, and the LED display panel 23 and the light-transmitting panel 24 return to their original positions under the reverse elastic force of the force-bearing spring block 2221. This allows for the quick removal of the LED display panel 23 and the light-transmitting panel 24, making the operation convenient.

[0024] Example 5, see attached document Figures 1-19 Based on Embodiment 4, in order to achieve interlocking between the display modules and avoid displacement between modules in strong winds that could affect the display effect: The lower center inner wall of the adjacent central connecting plate 22, LED display plate 23 and light-transmitting panel 24 is provided with grooves respectively, and the side of the central connecting plate 22, LED display plate 23 and light-transmitting panel 24 away from the groove is provided with a protrusion, and the outer surface of the protrusion is movably engaged with the inner wall of the groove. In this embodiment, refer to Figures 1-3 As shown, each set of central connecting plate 22, LED display plate 23 and light-transmitting panel 24 has matching grooves and protrusions on both sides. When adjacent structures are installed, the protrusions and grooves are interlocked, which can prevent the lateral displacement of LED display module 2 when subjected to extreme weather, further improve the stability of LED display module 2 installation and improve the overall display quality.

[0025] The working principle and usage process of this invention are as follows: In actual use, firstly, the LED display module is installed, and the LED beads between the corresponding LED display panel 23 and the light-transmitting panel 24 are matched and installed. The assembled whole is pushed towards the lamp body mounting back plate 21, so that the two sides of the LED display panel 23 are respectively embedded into the inner side of the lamp body mounting back plate 21. The snap-fit ​​block 231 connected to the inner side of the LED display panel 23 enters from the front side of the central connecting plate 22 and continues to push until the rubber sleeve 2311 on the snap-fit ​​block 231 is snapped into the docking groove 2200, achieving initial positioning. At this time, the two sets of swing hooks 232 installed inside the mounting groove 2310 are squeezed inward by the fixed hooks 221, and the elastic flap 233 is elastically compressed by the squeezing force on both sides. After the snap-fit ​​block 231 is completely snapped into the docking groove 2200, the swing hooks 232 and the fixed hooks 221 are automatically snapped together, completing the individual LED display panel 23 and the The light-transmitting panel 24 is quickly snapped into place with the lamp mounting back plate 21. Then, adjacent display modules are installed. Adaptive grooves and protrusions are set on both sides of each group of central connecting plates 22, LED display panels 23, and light-transmitting panels 24. When adjacent structures are installed, the protrusions and grooves are staggered to prevent displacement between modules in strong winds. When it is necessary to disassemble and maintain the independent LED display panels 23 and light-transmitting panels 24, the operator presses the force plate 222 on the back of the lamp mounting back plate 21 at the same time. The force plate 222 squeezes the swing hook 232 on the inner side, compresses the elastic flap 233, and releases the restriction of the swing hook 232 by the fixed hook 221. The operator can then pull the LED display panels 23 and light-transmitting panels 24 away from the lamp mounting back plate 21. Then, the force plate 222 is released, and the panels return to their original positions under the reverse elastic force of the force spring block 2221.
