Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of LED display, in particular to a small-pitch LED display module. Background Art
[0002] A small-pitch LED display module is a display unit that uses a high-density LED (light-emitting diode) dot matrix arrangement. Its pixel pitch (i.e., the distance between adjacent pixels) is usually less than 2mm. This display module achieves high pixel density, high resolution, and high-definition display effects through sophisticated circuit design, advanced packaging technology, and precise manufacturing processes. Multiple LED display modules are spliced to form a complete display screen. Screws are usually used for installation and disassembly. During the installation process, if the screws are installed improperly or with too much force, it is easy to damage the display module, affecting the display effect and increasing the cost of use. If the screws are not fixed correctly, it may also cause the display module to loosen or fall off, causing damage to it. In addition, screw installation can easily make the spacing between display modules too large or too small, resulting in an incoherent image during use, affecting the use effect.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] In order to solve the problem that the installation and removal of the fine pitch display module 22 is cumbersome and easy to cause damage to it, please refer to Figure 1-Figure 4, a small-pitch LED display module provided in this embodiment can reduce installation time and installation steps and improve installation efficiency. And reduce damage to the small-pitch display module 22 during installation and disassembly, including a shell 1, a display component 2 is detachably installed in the shell 1, and a fixing component 3 for fixing the display component 2 is provided in the shell 1. The display component 2 includes a chassis 21, and a small-pitch display module 22 is fixedly connected to the chassis 21. Card slots 23 are provided at all four ends of the chassis 21. The card slots 23 are adapted to the card blocks 33, the insert blocks 342 and the slots 351. The card slots 23 are used to connect the card blocks 33 to support the chassis 21. A connecting block 231 adapted to the slot 351 and the card slot 23 is slidably connected in one of the card slots 23 in the length direction of the chassis 21. The connecting block 231 is used to connect the card slot 23 of another chassis 21. A third spring 232 is fixedly connected between the connecting block 231 and the inner wall of the slot 23, and is used to restrict the movement of the connecting block 231. The fixing assembly 3 includes a bidirectional screw 31 rotatably mounted on the inner wall of the housing 1. The bidirectional screw 31 provides a movement path for a first fixing block 34 and a second fixing block 35. A symmetrically arranged clamping plate 32 is threadedly connected to the bidirectional screw 31 and slides within the housing 1. Multiple clamping blocks 33 are fixedly connected to the clamping plate 32. The clamping plate 32 is used to move the clamping blocks 33 toward or away from the chassis 21 to secure and release it, and to provide vertical support for the chassis 21. A first fixing block 34 is fixedly mounted on the inner wall of the housing 1, and a second fixing block 35 is slidably connected within the housing 1. The first and second fixing blocks 34, 35 provide lateral support for the chassis 21. A symmetrically arranged first spring 36 is fixedly connected between the first and second fixing blocks 34, 35, and is used to restrict the second fixing block 35. The first fixed block 34 is provided with a mounting slot 341, into which an insert block 342 is slidably connected. A second spring 343 is fixedly connected between the insert block 342 and the inner wall of the mounting slot 341, and the second spring 343 is used to limit the movement of the insert block 342. The second fixed block 35 is provided with a slot 351, which is used to connect with the connecting block 231. The length of the insert block 342 is greater than the depth of the mounting slot 341 and the slot 351. One end of the bidirectional screw 31 extends out of the housing 1, and a turning handle 37 is fixedly connected to the extended end of the bidirectional screw 31, which provides a force point for rotating the bidirectional screw 31.When installing the fine-pitch display module 22, first rotate the handle 37 to drive the bidirectional screw 31, so that the clamping plates 32 open up enough space for installation. Then, pull the second fixing block 35, and under the action of the first spring 36, open up enough space for installation in the horizontal direction. Then, place the first fine-pitch display module 22 in the installation space formed between the clamping plates 32. During placement, the insert block 342 is squeezed by the chassis 21 and retracted under the elastic force of the second spring 343. When the chassis 21 is lowered to the appropriate height and the slot 23 is flush with the insert block 342, the insert block 342 is no longer restricted by the chassis 21 and slides into the slot 23 under the action of the second spring 343, supporting it. Then, place the second fine-pitch display module 22, so that its slot 23 aligns with the connecting block 231 of the first fine-pitch display module 22. Under the action of the third spring 232, the connecting block 231 is positioned within the slot 23 of the second fine-pitch display module 22. The fine-pitch display modules 22 are installed in this manner. When the installation is complete, release the second fixing block 35 and retract it under the action of the first spring 36. At this time, the connecting block 231 of the small-pitch display module 22 is located in the slot 351. Under the elastic force of the first spring 36, the small-pitch display module 22 in the installation space is clamped in the horizontal direction. Then, turn the handle 37 so that the clamping plate 32 drives the clamping block 33 close to the chassis 21 to the slot 23. Under the restriction of the bidirectional screw 31, the clamping block 33 supports the chassis 21 in the vertical direction. Through simple operation, there is no need to install and remove screws tediously when installing and disassembling the small-pitch display module 22, and no other tools are required during installation and disassembly, which reduces installation time and installation steps and improves installation efficiency. It also reduces damage to the small-pitch display module 22 during installation and disassembly, reduces waste of resources and environmental pollution, ensures that the display effect of the display screen is consistent, and thus improves the display effect. Furthermore, it is possible to reduce installation errors, ensure that the spacing between the small-pitch display modules 22 is tight, reduce display disconnection, improve the continuity of color display, and thus improve the display effect.
[0028] Considering that the fine pitch display module 22 is prone to generate high temperature when used for a long time, and the closed environment makes it difficult to reduce the temperature, which easily affects its use effect, it is necessary to cool it down when the temperature is too high. Figure 1-Figure 4The outer shell 1 is provided with a heat dissipation component 4 for dissipating heat from the display component 2. The heat dissipation component 4 includes a plurality of heat sinks 41 fixedly mounted on the chassis 21 and connected to the small-pitch display module 22. The heat sinks 41 are made of materials with good thermal conductivity, such as aluminum alloy. First vents 42 are provided at both ends of the length direction of the outer shell 1, and multiple groups of second vents 45 are provided at both ends of the width direction of the outer shell 1. The first vents 42 and the second vents 45 are used to ventilate the interior of the outer shell 1 so that air can flow in and out of the interior. The second vents 45 are parallel to the heat sink 41. The gap between the heat sinks 41 is greater than the spacing between the lamp beads on the small-pitch display module 22. The length and width of the first vents 42 and the second vents 45 are both greater than the heat sink 41, ensuring that enough air can enter the interior of the outer shell 1 and blow toward the surface of the heat sink 41. When the fine-pitch display module 22 is in use, the heat generated is transferred to the heat sink 41 through heat conduction. The heat sink 41 increases the heat dissipation area, dissipating the heat and conducting it into the air, improving heat dissipation efficiency. Air can flow in and out of the housing 1 through the first and second vents 42 and 45, dissipating the heat as it circulates. This prevents the fine-pitch display module 22 from overheating during use, maintains stable brightness output, and prevents overheating, which can cause blurring or flickering, thereby ensuring safe operation of the device.
[0029] Considering that when the air enters and leaves the housing 1 to cool the temperature on the heat sink 41, hot air is likely to remain in the housing 1, resulting in poor air circulation and making it difficult for the temperature to drop quickly, it is necessary to guide the air so that it can be discharged quickly. Figure 1 - Figure 4 shows an air inlet fan 43 and an air outlet fan 44 fixedly mounted on the inner wall of the housing 1, located on one side of the first vent 42. When installing the fine-pitch display module 22, the power supply to the air inlet fan 43 and the air outlet fan 44 is connected. When the fine-pitch display module 22 is in use, the power is turned on, causing the air inlet fan 43 and the air outlet fan 44 to operate. The air inlet fan 43 draws in external air, and the air outlet fan 44 rapidly exhausts the air inside the housing 1, allowing the air inside to circulate and convert quickly, accelerating the flow of air. This allows the temperature on the heat sink 41 to dissipate rapidly under the flow of air, thereby preventing the fine-pitch display module 22 from overheating, improving heat dissipation efficiency, and maintaining a stable temperature. This ensures that the fine-pitch display module 22 maintains stable image quality output and display effects during long-term operation, thereby extending the module's service life and improving the reliability of the device.
