Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a high-perforation curved LED outdoor display screen. Background Technology

[0002] High-perforation curved LED outdoor displays are outdoor display devices that combine a special structure with LED technology. Their high-perforation design provides a sense of transparency and lightweight characteristics, while the curved structure can conform to irregular scene shapes and possesses the weather resistance required for outdoor environments. Widely used in architectural decoration, transportation hubs, cultural and tourism landmarks, and large-scale events, they enhance visual aesthetics through high integration with the environment, reduce wind resistance and lower installation and maintenance costs. Furthermore, the curved design enhances the immersive experience of information delivery, balancing functionality and artistry, and achieving a harmonious coexistence between outdoor displays and the environment.

[0003] A search revealed Chinese Patent Publication No. CN203573586U, which discloses an outdoor LED display screen. The screen includes a connecting strip, a power distribution box, and multiple LED display modules arranged side-by-side. Each LED display module is rectangular, with multiple light-emitting elements on its front and connecting terminals on its back, which are electrically connected to the LED display panel. The power distribution box has multiple mating terminals that engage with the connecting terminals of the LED display modules. The multiple LED display modules are arranged side-by-side along their width. The connecting strip extends along the width of the LED display modules and secures them. The power distribution box extends along the width of the LED display modules and is fixed to the back of the modules. The mating terminals of the power distribution box are electrically connected to the connecting terminals of the LED display modules. This outdoor LED display screen features a simple structure, small size, low manufacturing cost, and ease of installation and maintenance after disassembly.

[0004] The aforementioned patent specification mentions that "when it is necessary to disassemble and repair a single display module, simply remove the fixing bolts of the single display module, and then push the display module from the front of the distribution box towards the front of the display module, so that the connection terminals of the LED display module are disengaged from the mating terminals of the distribution box, thus completing the disassembly work. This disassembly process is simple and convenient, thereby making this utility model easy to maintain later." Although the aforementioned patent facilitates later maintenance, it cannot achieve multi-angle adjustment. Therefore, a high-perforation curved LED outdoor display screen is proposed to solve the above problem. Utility Model Content

[0015] 2. In this utility model, by using a limiting plate and a connecting plate, the connecting plate and the limiting plate, the limiting plate and the spring, and the spring and the pressing plate, the position of the module is avoided from being offset during installation. Mechanical logic replaces manual judgment, and the limiting plate and the connecting plate establish a rigid benchmark to ensure positioning accuracy. The elastic adjustment of the spring and the pressing plate is compatible with the tolerance of the components. This not only eliminates the screen defects and long-term chain failures caused by module installation offset, but also reduces the dependence on manual skill. Attached Figure Description

[0018] Example: A high-perforation curved outdoor LED display screen, referenced Figure 1 The system includes a display panel 1, which is the basic load-bearing component of the overall structure, providing an installation reference for other mechanisms and ensuring that all parts work together. A frame mechanism 2 is slidably connected inside the display panel 1. The frame mechanism 2 can flexibly adjust its relative position to the display panel 1 by sliding inside the display panel 1, which facilitates precise docking and provides a stable frame for installation. An auxiliary mechanism 3 is slidably connected to the outside of the display panel 1. The auxiliary mechanism 3 slides outside the display panel 1 and can cooperate with the installation action of the frame mechanism 2 to provide external auxiliary positioning of the parts and improve the positional accuracy during installation. Specifically, the display panel 1 serves as the basic load-bearing component. Its internal frame mechanism 2 achieves precise docking by sliding and adjusting its position, providing a stable frame. The external auxiliary mechanism 3 slides and cooperates to assist in limiting the position and improve the installation accuracy. The three work together to ensure the overall installation is accurate and stable.

[0019] Reference Figure 3 , Figure 4 The frame mechanism 2 includes a module 21, which is the core component of the display function. Its structural design is adapted to the installation process, laying the foundation for subsequent cooperation with the fixed frame 22. The outer side of the module 21 is slidably connected to the inside of the display panel 1, and its position can be adjusted to accurately align with the installation position, facilitating subsequent cooperation with the fixed frame 22. The other side of the module 21 is slidably connected to the fixed frame 22, providing installation support for the module 21 and ensuring the stability of the module 21 during installation. The top of the fixed frame 22 is fixedly connected to a positioning pin 25, which can provide accurate positioning for the docking of the fixed frame 22 and the component, reducing positional deviation during installation. The top of the fixed frame 22 is fixedly connected to a middle fixing rod 24, which can enhance the connection stability between the fixed frame 22 and related components and prevent loosening after installation. The fixed frame 22 is slidably connected to a control mechanism 23. The control mechanism 23 slides inside the fixed frame 22 and can be flexibly adjusted to adapt to the installation of the module 21, ensuring power and signal transmission. The outside of the fixed frame 22 is fixedly connected to a detachable arc-shaped locking seat 28, which can help the fixed frame 22 adapt to arc-shaped installation requirements and improve the adaptability of the structure and the scene. The outside of the fixed frame 22 is slidably connected to a middle lower lock 29, which can cooperate with the component by sliding to further strengthen the connection of the fixed frame 22 and enhance the overall stability. The outer side of the fixed frame 22 is fixedly connected with a lower locking piece 210, and the middle lower lock 29 can cooperate with the lower locking piece 210 by sliding to further strengthen the connection of the fixed frame 22 and enhance the overall stability. The top of the fixed frame 22 is rotatably connected with a handle lock 26. The handle lock 26 can quickly lock and unlock the fixed frame 22 by rotating, which is convenient for installation and disassembly. The outer side of the fixed frame 22 is fixedly connected with corner protectors 27. The corner protectors 27 can protect the edges and corners of the fixed frame 22 and reduce damage caused by collisions during installation or use. Specifically, in frame mechanism 2, module 21 serves as the display core.

Corner guards 27 provide protection. Detachable arc lock seat 28 adapts to arc installation requirements. Control mechanism 23 slides within fixed frame 22 to ensure power and signal transmission. All components work together to ensure accurate, stable, and convenient installation and operation of module 21.

[0020] Reference Figure 5 , Figure 6 The control mechanism 23 includes a control box 231, which is the core carrier for control and power supply. It integrates various components to form a complete functional link and supports the operation of the module 21. The outer side of the control box 231 is slidably connected to the inside of the fixed frame 22. By sliding inside the fixed frame 22, the control box 231 can be adjusted to precisely align with the installation position, ensuring smooth cooperation with the parts. The bottom of the control box 231 is fixedly connected to a power socket 232, which provides an interface for external power supply, ensuring the stability and convenience of power transmission. A signal connector 233 is fixedly connected to the bottom of the control box 231. The signal connector 233 is used to connect external signal lines to realize the stable transmission of external signals to the control box 231. A signal fixing line 235 is fixedly connected to the top of the control box 231. The signal fixing line 235 transmits the signals in the control box 231 to the module 21 to ensure the stable transmission of display signals. A power fixing line 236 is fixedly connected to the top of the control box 231. The power fixing line 236 delivers the power in the control box 231 to the module 21 to provide power support for the operation of the module 21. A power supply 239 is fixedly connected inside the control box 231. The power supply 239 provides power to the control box 231 and connected components and is the power source for the entire control mechanism 23. A signal connector 237 is fixedly connected inside the control box 231. The signal connector 237 is used to relay signals and ensure stable transmission and connection of signals inside the control box 231. Two hinges 234 are fixedly connected to the outside of the control box 231. The hinges 234 enable the control box 231 to open and close, which facilitates the inspection and maintenance of internal components. Multiple power copper pin seats 238 are fixedly connected inside the control box 231. The power copper pin seats 238 are used to stably connect the power lines and ensure reliable power transmission inside the control box 231. Specifically, the control mechanism 23 is centered on the control box 231. It slides and adjusts its position within the fixed frame 22 to achieve precise docking. The power supply 239 provides power, which is transmitted to the module 21 via the power copper pin seat 238 and the power fixed line 236. The power socket 232 ensures external power access. The signal is transmitted through the signal socket 233 and transmitted to the module 21 via the signal connector 237 and the signal fixed line 235. The hinge 234 facilitates the opening and closing of the control box 231 for maintenance. All components work together to achieve stable power supply and signal transmission, supporting the operation of the module 21.

[0021] Reference Figure 1 , Figure 2 The auxiliary mechanism 3 includes a limiting plate 31, which is a reference component for auxiliary positioning and provides basic support for the coordinated operation of subsequent components. The inner side of the limiting plate 31 is slidably connected to the outer side of the display plate 1. By sliding on the outer side of the display plate 1, the limiting plate 31 can be adjusted to adapt to the installation requirements of the fixed frame 22 and establish a positioning reference. The outer side of the limiting plate 31 is rotatably connected to two connecting plates 33. The connecting plates 33 can be rotated to adjust their angle and drive the limiting plate 34 to move, thereby guiding the installation trajectory of the module 21. The end of the connecting plate 33 away from the limiting plate 31 is rotatably connected to the limiting plate 34. The limiting plate 34 moves under the drive of the connecting plate 33 to form a space to accommodate the module 21 and perform initial positioning of the module 21. Multiple springs 35 are fixedly connected inside the limiting plate 34. The springs 35 provide elastic force and clamp the module 21 stably through the extrusion plate 36, buffering the position deviation during installation. The extrusion plate 36 is fixedly connected to the other side of the multiple springs 35. Under the action of the springs 35, the extrusion plate 36 fits against the side of the module 21 to achieve elastic clamping of the module 21 and ensure its position is stable during installation. The outer side of the extrusion plate 36 is slidably connected inside the limiting plate 34 and can flexibly adjust its position with the extension and retraction of the springs 35 to enhance the clamping adaptability of the module 21 and ensure a tight fit. Two connecting plates 32 are rotatably connected to one side of the limiting plate 31 to assist the limiting plate 31 in accurately positioning on the outside of the display plate 1 and to work with the connecting plates 33 to optimize the movement trajectory of the limiting plate 34. Specifically, in auxiliary mechanism 3, the limiting plate 31 slides and adjusts its position on the outside of the display plate 1 to establish a positioning reference. It drives the limiting plate 34 to move through the connecting plate 2 33, forming a accommodating space to initially limit the module 21. The spring 35 inside the limiting plate 34 provides elastic force to push the squeezing plate 36 to elastically clamp the module 21, buffering deviations and ensuring that the module 21 is stable in position during installation. All components work together to assist the module 21 in accurate installation.

[0022] Working principle: When the operator needs to install the module 21 and the fixed frame 22, the two limiting plates 31 can be pulled to place the limiting plates 31 on the outside of the fixed frame 22. Then, the limiting plates 34 on both sides are pulled outward together, and the module 21 is placed inside the two limiting plates 34. This causes the two pressing plates 36 on the inside of the limiting plates 34 to press to both sides. The module 21 is clamped by the multiple springs 35 set on the inside. Then, the limiting plates 34 are moved to the outside of the fixed frame 22, causing the connecting plate 23 to retract. After the module 21 slides to the outside of the fixed frame 22, the module 21 is installed through the components on the outside of the fixed frame 22.

[0023] The power supply 239 inside the control box 231 powers the components. The control box 231 is designed with many heat dissipation teeth to enhance heat dissipation. The cabinet frame is thin and simple in structure, with good strength and high precision, and can be used for long-term indoor fixed installation. The LED display module 21 is fixed to the cabinet by magnetic attraction and screws that do not come loose. Individual modules 21 can be quickly disassembled and replaced, and can also achieve quick maintenance of modules 21 in the later stage.
