Description

Technical Field

[0001] This utility model relates to the field of LED display module technology, and in particular to an impact-resistant traffic direct-insertion LED display module. Background Technology

[0002] In the transportation sector, LED display modules are widely used in traffic lights, guidance screens, and other facilities, playing a crucial role in ensuring traffic safety and improving traffic efficiency. Traffic through-hole LED display modules, as an important type, require high reliability and stability in complex outdoor environments. Especially when facing various potential impacts, such as vehicle collisions, falling objects, and severe weather, the structural integrity and display function of the module must be effectively guaranteed, which places high demands on its impact resistance.

[0003] Existing direct-plug LED display modules for traffic applications typically employ a simple outer casing to encapsulate core components such as the PCB board and LED beads. Their technical principles primarily revolve around basic circuit connections and the LED light-emitting principle, ensuring the display module can properly receive signals and display corresponding information. For casing fixation, screws are commonly used to assemble the various components, while some also employ adhesive bonding to enhance sealing and stability.

[0004] However, this traditional mechanical structure and fixing method has some drawbacks. In actual use, when maintenance or repair of the display module is required, the disassembly and installation of its outer casing is inconvenient. Due to the use of complex screw fixing or gluing methods, the operation steps are cumbersome and time-consuming, and maintenance personnel need to use various tools for disassembly. Slight carelessness can easily lead to scratches or damage to the outer casing, and may even damage internal components such as the PCB board and LED beads, thereby increasing maintenance costs, reducing the lifespan of the display module, and affecting the stable operation of the traffic display equipment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an impact-resistant traffic direct-plug LED display module, which aims to improve the problem that the housing of traditional traffic direct-plug LED display modules is difficult to disassemble and install. In the past, the housing of the module may be fixed with complex screws or glued, which is cumbersome, time-consuming and easy to damage the housing or internal components due to improper operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an impact-resistant traffic direct-insertion LED display module, comprising a housing, a module body fixedly connected to the inner wall of the housing, a PCB board slidably connected to the outer wall of the module body, a second housing slidably connected to the outer wall of the housing, a disassembly assembly provided on the inner wall of the module body, and a replacement assembly provided on the inner wall of the PCB board.

[0007] The disassembly assembly includes a fixing ball, the outer wall of which is disposed on the inner wall of a first outer shell. A connecting cylinder is fixedly connected to the inner wall of the first outer shell. A switch is slidably connected to the inner wall of the connecting cylinder. A spring is fixedly connected to the inner wall of the switch. A fixing post is fixedly connected to one end of the spring. A push platform is fixedly connected to one end of the switch. A compression ball is fixedly connected to the lower surface of the push platform. A second push platform is fixedly connected to the lower surface of the push platform. A second spring is fixedly connected to the lower surface of the second push platform. A fixing cylinder is fixedly connected to the outer wall of the second outer shell. A tempered glass screen is fixedly connected to the outer wall of the first outer shell.

[0008] Furthermore, the disassembly assembly includes a fixing block, the outer wall of which is slidably connected to the inner wall of the PCB board, a connecting column fixedly connected to the outer wall of the module body, a sliding column fixedly connected to the outer wall of the fixing block, a spring three fixedly connected to the outer wall of the sliding column, a support platform slidably connected to the outer wall of the sliding column, and a spring four fixedly connected to the outer wall of the support platform.

[0009] Furthermore, one end of the spring is fixedly connected to the outer wall of the support platform, and the spring is used to push the sliding column to move.

[0010] Furthermore, the outer wall of the fixing block is slidably connected to the inner wall of the connecting column, and the fixing block is used to limit the position of the connecting column.

[0011] Furthermore, one end of the spring is fixedly connected to the inner wall of the PCB board, and the spring is used to push the support platform to move.

[0012] Furthermore, the outer wall of the fixed ball is slidably connected to the inner wall of the connecting cylinder, and the fixed ball is used to connect the fixed cylinder and the connecting cylinder.

[0013] Furthermore, the outer wall of the extrusion ball is slidably connected to the inner wall of the connecting cylinder, and the extrusion ball is used to push the fixed ball to move.

[0014] Furthermore, the outer wall of the fixing column is slidably connected to the inner wall of the connecting cylinder, and the fixing column is used to limit the switch.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when installing the outer shell, pressing the switch moves the pusher platform, pushing the squeezing ball to move the fixed ball out from the connection position, thus realizing the installation of the outer shell. When disassembling, pressing the fixing post triggers the spring to rebound, pushing the relevant structure to smoothly separate the outer shell. This solves the problem that the outer shell of traditional traffic direct-insert LED display modules is difficult to disassemble and install. In the past, the module outer shell may have used complex screw fixing or gluing methods, which were cumbersome, time-consuming, and prone to damage to the outer shell or internal components due to improper operation. This invention achieves the effects of convenient disassembly and installation of the outer shell, improved maintenance efficiency, reduced maintenance costs, reduced risk of component damage, and ensured stable operation of the display module.

[0017] 2. In this utility model, when the module body is installed, pressing causes the connecting column to squeeze the fixing block, which in turn drives the sliding column to compress the spring. The spring rebounds and allows the fixing block to fit against the connecting column. When disassembling, the PCB board is pulled, and separation is achieved due to the inclined surface of the fixing block. This achieves convenient installation and disassembly, facilitates replacement or maintenance, improves the maintainability of the module, and ensures that the display module can operate stably for a long time.

[0025] 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.

[0026] Reference Figure 1 - Figure 5 The present invention provides an embodiment of an impact-resistant traffic direct-insertion LED display module, comprising a housing 1 2, a module body 1 fixedly connected to the inner wall of the housing 1 2, a PCB board 15 slidably connected to the outer wall of the module body 1, a housing 2 3 slidably connected to the outer wall of the housing 1 2, a disassembly assembly provided on the inner wall of the module body 1 for separating the housing 1 2 from the housing 2 3 for easy maintenance, and a replacement assembly provided on the inner wall of the PCB board 15 for quickly replacing the module body 1.

[0027] The disassembly assembly includes a fixing ball 12, which connects the fixing cylinder 6 and the connecting cylinder 7. The installation and disassembly of the outer shell 2 and the outer shell 3 are achieved by changing the position of the fixing ball 12. The outer wall of the fixing ball 12 is set on the inner wall of the outer shell 2. The connecting cylinder 7 is fixedly connected to the inner wall of the outer shell 2. The switch 5 is slidably connected to the inner wall of the connecting cylinder 7. The spring 8 is fixedly connected to the inner wall of the switch 5. The fixing post 9 is fixedly connected to one end of the spring 8. The push platform 10 is fixedly connected to one end of the switch 5. The compression ball 11 is fixedly connected to the lower surface of the push platform 10. The push platform 2 13 is fixedly connected to the lower surface of the push platform 10. The spring 2 14 is fixedly connected to the lower surface of the push platform 2 13. The fixing cylinder 6 is fixedly connected to the outer wall of the outer shell 3. The tempered glass screen 4 is fixedly connected to the outer wall of the outer shell 2 and is installed on the outer wall of the outer shell 2. It is mainly used to resist the scratches of sharp objects and the impact of a certain strength.

[0028] Specifically, when installing outer casing 1 2 and outer casing 2 3, press switch 5. Switch 5 slides inside connecting cylinder 7. The fixed column 9 is squeezed, causing spring 1 8 to compress. Switch 5 drives push platform 1 10 to move. The compression ball 11 pushes the fixed ball 12 out of the connection position between fixed cylinder 6 and connecting cylinder 7. The fixed column 9 slides the limit switch 5 inside connecting cylinder 7. When push platform 1 10 moves, push platform 2 13 moves down to compress spring 2 14. When disassembling, manually press the fixed column 9. After the fixed column 9 moves to a suitable distance, spring 2 14 rebounds and pushes push platform 2 13. Push platform 2 13 pushes the fixed ball 12 to slide, causing fixed cylinder 6 to separate from connecting cylinder 7.

[0029] Reference Figure 1 , Figure 4 and Figure 5The disassembly assembly includes a fixing block 17, which is inclined to facilitate separation from the connecting post 16. The outer wall of the fixing block 17 is slidably connected to the inner wall of the PCB board 15. The connecting post 16 is fixedly connected to the outer wall of the module body 1. A sliding post 18 is fixedly connected to the outer wall of the fixing block 17. A spring 19 is fixedly connected to the outer wall of the sliding post 18. A support platform 21 is slidably connected to the outer wall of the support platform 21. A spring 20 is fixedly connected to the outer wall of the support platform 21. One end of the spring 19 is fixedly connected to the outer wall of the support platform 21. The spring 19 is used to push the sliding post 18 to move. The outer wall is slidably connected to the inner wall of the connecting column 16. The fixing block 17 is used to limit the connecting column 16. One end of the spring 4 20 is fixedly connected to the inner wall of the PCB board 15. The spring 4 20 is used to push the support platform 21 to move. The outer wall of the fixing ball 12 is slidably connected to the inner wall of the connecting cylinder 7. The fixing ball 12 is used to connect the fixing cylinder 6 and the connecting cylinder 7. The outer wall of the extrusion ball 11 is slidably connected to the inner wall of the connecting cylinder 7. The extrusion ball 11 is used to push the fixing ball 12 to move. The outer wall of the fixing column 9 is slidably connected to the inner wall of the connecting cylinder 7. The fixing column 9 is used to limit the switch 5.

[0030] Specifically, when replacing or maintaining the module body 1, the connecting post 16 on the module body 1 cooperates with the fixing block 17 inside the PCB board 15. The outer wall of the fixing block 17 acts as a limit inside the connecting post 16. When the module body 1 is pressed inward, the connecting post 16 squeezes the fixing block 17. The fixing block 17 drives the sliding post 18 to move and compress the spring 19. The sliding post 18 slides inside the support platform 21. The support platform 21 squeezes the spring 20. After installation, the spring 19 and the spring 20 rebound and push the sliding post 18, causing the fixing block 17 to fit tightly with the connecting post 16. When disassembling, because the fixing block 17 is inclined, the PCB board 15 can be pulled out directly to achieve separation.

[0031] Working Principle: When an impact-resistant traffic-grade through-hole LED display module is required, and when installing housing 2 and housing 3, pressing switch 5 causes switch 5 to slide within connecting cylinder 7. This compresses the fixing post 9, which in turn compresses spring 8. Simultaneously, switch 5 moves push platform 10, causing the compression ball 11 on the lower surface of push platform 10 to push the fixing ball 12 to slide, moving it out of the connection position between fixing cylinder 6 and connecting cylinder 7. The sliding of fixing post 9 within connecting cylinder 7 limits the movement of switch 5, ensuring stable sliding and enabling the installation of housing 3 and housing 2. As push platform 10 moves... When the device moves, the second pushing platform 13 will also move down, compressing the second spring 14. When it is necessary to separate the outer shell 2 from the outer shell 3, first press the fixing post 9 manually. When the fixing post 9 moves to the appropriate distance, the second spring 14 rebounds and pushes the second pushing platform 13 to move. At this time, the second pushing platform 13 pushes the fixing ball 12 to slide. When the fixing ball 12 moves to the appropriate distance, the fixing cylinder 6 and the connecting cylinder 7 automatically separate, so that when the outer shell 2 and the outer shell 3 are disassembled, it is convenient to carry out internal maintenance. The tempered screen 4 can resist the scratches of sharp objects and the impact of a certain strength, providing direct protection for the front of the module body 1.

[0032] Furthermore, when the module body 1 needs to be replaced or maintained, the connecting post 16 on the module body 1 cooperates with the fixing block 17 inside the PCB board 15. The outer wall of the fixing block 17 is inside the connecting post 16, which plays a limiting role. When the module body 1 is pressed inward, the connecting post 16 squeezes the fixing block 17, and the fixing block 17 drives the sliding post 18 to move. The sliding post 18 compresses the spring 19. At this time, the sliding post 18 slides inside the support platform 21. The support platform 21 squeezes the spring 20. The rebound of the spring 19 and the spring 20 pushes the sliding post 18 to drive the fixing block 17 to move. At this time, the fixing block 17 and the connecting post 16 are tightly fitted, so that the module body 1 is installed on the PCB board 15. When disassembling, because the fixing block 17 is inclined, the PCB board 15 can be pulled out directly to achieve separation, making it convenient to remove the module body 1 from the upper PCB board 15 for replacement or maintenance.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
