Description

Technical Field

[0001] This utility model belongs to the field of LED display technology, and more specifically, it relates to a modular combined LED display module. Background Technology

[0002] As a core carrier of modern information display, LED display modules are widely used in advertising media, stage performances, traffic guidance, and other fields, effectively achieving high-brightness and wide-color-gamut dynamic image presentation. However, traditional LED display modules typically adopt an integrated monolithic structure design, integrating LED chips, driver circuits, and other components onto the same substrate to form a complete display unit. In practical applications, to ensure the consistency and stability of display effects, this structure often employs an integrated packaging and connection method to ensure stable operation of the display module. However, when a part of the LED display module malfunctions, due to its integrated design, maintenance personnel cannot replace the damaged part individually; they must disassemble and replace the entire display module. This not only increases maintenance costs but also prolongs maintenance time, leading to increased downtime for the display equipment. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a modular combined LED display module, which solves the technical problem in the prior art that traditional LED display modules cannot individually disassemble and replace partially damaged parts.

[0004] The purpose and effect of this modular combined LED display module are achieved by the following specific technical means:

[0005] A modular combined LED display module includes a mounting frame and multiple display units. The mounting frame has multiple sets of dividing rods forming multiple sets of mounting grids. The mounting frame has multiple sets of mounting brackets located within the mounting grids, and the display units are mounted within the mounting grids. Each display unit includes a substrate and a display body. The substrate is located within the mounting grid and mounted on the mounting bracket. The display body is mounted on one side of the substrate and contacts the display bodies of adjacent display units, forming a display surface through the multiple sets of display bodies.

[0006] According to a preferred embodiment, an installation frame is provided at the edge of the installation grid, the substrate is fitted inside the installation frame, an installation platform is provided inside the installation grid, an installation groove is provided on the installation platform, a first magnetic ring is provided inside the installation grid, and the first magnetic ring is fitted inside the installation groove; a second magnetic ring is provided on one side of the substrate, and the first magnetic ring and the second magnetic ring attract each other.

[0007] According to a preferred embodiment, a limiting frame is provided at the edge of the substrate, and a positioning frame is provided on one side of the substrate. The positioning frame is located inside the limiting frame, and the height of the limiting frame is greater than the height of the positioning frame. A component part is provided on one side of the display screen body, and the component part is engaged in the positioning frame. One side of the display screen body contacts the limiting frame to form a sealed cavity, and the positioning frame is located inside the sealed cavity.

[0008] According to a preferred embodiment, a plurality of fixing members are provided on one side of the substrate, each fixing member including a pull rod. A plurality of fixing sleeves are provided on one side of the substrate. The mounting bracket has fixing through holes corresponding to the fixing sleeves, and the fixing sleeves pass through the fixing through holes. A fixing block is provided at one end of the pull rod, and the fixing block is engaged in the fixing sleeve. Limiting rods are provided on both sides of the fixing sleeve, and limiting plates are provided on both sides of the fixing block. The limiting plates have through holes, and the limiting plates are sleeved on the limiting rods through the through holes. The limiting plates are slidably connected to the limiting rods.

[0009] According to a preferred embodiment, the fixing member further includes multiple sets of fixing claws, the fixing claws being rotatably connected to the fixing sleeve, one end of the fixing claw contacting the fixing block, and the other end contacting the mounting bracket; the fixing block is provided with a fixing buckle, and the fixing sleeve is provided with a first slot and a second slot corresponding to the fixing buckle, the first slot being located between the base plate and the second slot, and the fixing buckle being engaged in the second slot.

[0010] According to a preferred embodiment, the substrate has multiple sets of heat dissipation through holes, which are hexagonal in shape, forming a honeycomb structure. The mounting frame has multiple sets of heat dissipation grooves corresponding to the heat dissipation through holes.

[0011] According to a preferred embodiment, a sealing ring is provided between the substrate and the mounting frame, and a positioning groove is provided on the substrate. The sealing ring is engaged in the positioning groove and contacts the opening surface of the mounting frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The mounting frame is divided into multiple independent mounting squares by dividing the space into distinct sections. Each square contains a precisely positioned mounting bracket equipped with a magnetic mounting structure. The first and second magnetic rings in this structure attract each other, ensuring quick positioning and secure fixation of the display unit. When a partial display unit malfunctions, the operator only needs to press the fixing claw to disengage it from the second slot and simultaneously release the magnetic connection to easily remove the damaged module individually. This eliminates the need to disassemble the entire display screen, significantly reducing repair difficulty and time costs, and improving maintenance efficiency.

[0014] 2. The dual-sealing structure formed by the limiting frame and the positioning frame, together with the sealing ring set in the positioning groove of the substrate and the waterproof rubber ring at the magnetic connection part, constitutes multiple protective barriers to effectively resist the intrusion of dust and moisture, making it suitable for use in complex environments. At the same time, the honeycomb heat dissipation holes distributed in a hexagonal array on the substrate, which are connected vertically with the heat dissipation grooves opened on the mounting frame, form a three-dimensional high-efficiency heat conduction channel, which can quickly dissipate the heat generated by the LED beads, effectively reduce the module operating temperature, and extend the service life.

Detailed Implementation

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0026] Example:

[0027] like Figures 1 to 8 As shown, this utility model provides a modular combined LED display module, including a mounting frame 11 and display units. The mounting frame 11 serves as the basic support structure for the entire LED display module, providing a mounting carrier for other components. Multiple sets of dividing rods 12 internally divide the internal space of the mounting frame 11 into multiple mounting squares. These dividing rods 12 not only serve as spatial dividers but also enhance the overall structural strength of the mounting frame 11, making it less prone to deformation under external forces, thus ensuring the stability of the entire display module. Multiple sets of mounting brackets 13 are provided on the mounting frame 11, located within the mounting squares. The main function of the mounting brackets 13 is to provide mounting positions and support for the display units. They are securely connected to the mounting frame 11, capable of bearing the weight of the display units, and after installation, evenly distribute the weight of the display units onto the mounting frame 11, avoiding excessive local stress. Simultaneously, the position and shape of the mounting brackets 13 are rationally planned, allowing the display units to be accurately installed within the mounting squares, ensuring the relative positional relationship between each display unit and laying the foundation for the subsequent formation of a complete display surface.

[0028] The display unit is the core component that realizes the display function of the LED display screen, and it includes a substrate 21 and a display screen body 22. The substrate 21 is located within the mounting grid and mounted on the mounting bracket 13. The substrate 21 serves as a carrier for the display screen body 22 and other electronic components, playing a role in fixing and connecting them. It provides a stable mounting surface for the display screen body 22, and various circuit lines are also arranged on the substrate 21 for transmitting electrical signals, transmitting externally input signals to the display screen body 22, and ensuring that the display screen body 22 can display content normally as required. In addition, the substrate 21 also needs to have a certain strength and heat dissipation performance to bear the weight of the display screen body 22 and other components, and to dissipate the heat generated during operation in a timely manner to ensure the normal operation of the entire display unit.

[0029] The display screen body 22 is mounted on one side of the substrate 21 and is a key component for displaying images and text. The display screen body 22 consists of multiple LED beads and other light-emitting elements. By controlling the on / off state and intensity of these elements, different images and text information are displayed. When multiple display units are combined, the display screen body 22 in each unit contacts the display screen body 22 in adjacent units. Through the cooperation of multiple sets of display screen bodies 22, a complete display surface is formed. This combination method allows the size of the display screen to be flexibly adjusted according to actual needs. It can be used to form smaller displays for indoor information display or to splice together large outdoor displays for advertising and other purposes. Each display screen body 22 undertakes a corresponding display task within the display surface. They work closely together to convert the input signal into a clear and continuous image, thereby realizing the information display function of the LED display screen.

[0030] like Figure 2 , Figure 4 , Figure 5 , Figure 8 As shown, in the LED display module, the mounting frame 14 at the edge of the mounting grid provides a basic positioning boundary for the substrate 21. When the substrate 21 is engaged within the mounting frame 14, the mounting frame 14 can initially limit the substrate 21, preventing it from moving freely in the horizontal direction, thus keeping the substrate 21 in a relatively fixed position within the mounting grid, providing a stable foundation for subsequent installation and splicing operations. The mounting platform 15 within the mounting grid serves as a support and load-bearing element, providing a platform for placing the first magnetic ring 17. The mounting groove 16 on the mounting platform 15 is sized to match the first magnetic ring 17, and the first magnetic ring 17 is engaged within the mounting groove 16. This arrangement effectively prevents the first magnetic ring 17 from shifting or falling off during use, ensuring the stability of the first magnetic ring 17's position.

[0031] The first magnetic ring 17 and the second magnetic ring 23 disposed on one side of the substrate 21 attract each other. This characteristic plays an important role in the installation process of the display unit. When the display unit needs to be installed, the operator brings the substrate 21 close to the mounting grid. Within a certain distance, the magnetic force between the first magnetic ring 17 and the second magnetic ring 23 automatically guides the substrate 21 to move to the correct installation position, reducing the manual alignment steps. At the same time, the magnetic force maintains a certain connection between the substrate 21 and the mounting frame 11. While initially fixing the display unit, it also provides convenient conditions for subsequent more stable fixing operations, making the installation process of the display unit within the mounting grid more convenient and efficient. Furthermore, it can maintain a relatively stable positional relationship during use, ensuring the normal operation of the display module.

[0032] like Figure 3 , Figure 6 , Figure 7 As shown, the limiting frame 24 and positioning frame 25 at the edge of the substrate 21 provide dual protection for the installation of the display body 22. The limiting frame 24 is higher than the positioning frame 25, forming a stepped structure. The positioning frame 25 is located inside the limiting frame 24, and its main function is to provide space for the components of the display body 22. When the display body 22 is installed, the components can be locked in the positioning frame 25, thereby initially limiting the display body 22 in the horizontal direction and preventing it from shifting left or right. The limiting frame 24 further enhances the fixing effect on the display body 22. When one side of the display body 22 contacts the limiting frame 24, a sealed cavity is formed between them, and the positioning frame 25 and the components of the display body 22 are all located in this sealed cavity. This sealed cavity can prevent external dust, moisture, etc. from entering, providing a certain degree of protection for the components of the display body 22 and reducing the interference of external environmental factors on the normal operation of the display body 22. Meanwhile, the limiting frame 24 also limits the display body 22 in the vertical direction. Together with the positioning frame 25, it fixes the display body 22 from multiple directions, ensuring that the display body 22 is stably installed on the substrate 21, thus guaranteeing the display effect and service life of the LED display module.

[0033] Multiple sets of fixing components arranged on one side of the substrate 21 play a crucial role in securely mounting the substrate 21 onto the mounting bracket 13. The fixing sleeve 26 among the fixing components works in conjunction with the fixing through hole 18 on the mounting bracket 13. When installing the display unit, the fixing sleeve 26 passes through the fixing through hole 18, initially connecting the substrate 21 to the mounting bracket 13 and providing basic positioning. A fixing block 32 at one end of the pull rod 31 is engaged within the fixing sleeve 26. Pulling the pull rod 31 moves the fixing block 32 within the fixing sleeve 26. Limiting rods 33 on both sides of the fixing sleeve 26 cooperate with limiting plates 34 on both sides of the fixing block 32. Through holes on the limiting plates 34 fit onto the limiting rods 33, and the limiting plates 34 can slide along the limiting rods 33. During the pulling of the pull rod 31, the limiting plates 34 slide on the limiting rods 33, making the movement of the fixing block 32 within the fixing sleeve 26 more stable and preventing displacement or wobbling. When the fixing block 32 moves to the appropriate position, it can generate a pulling force on the substrate 21, so that the substrate 21 is fixed on the mounting frame 13, which enhances the connection strength between the substrate 21 and the mounting frame 13, prevents the substrate 21 from loosening or falling off the mounting frame 13 during use, and ensures the structural stability and reliability of the entire LED display module.

[0034] The fixing claw 35 in the fastener further enhances the stability of the connection between the substrate 21 and the mounting bracket 13. The fixing claw 35 is rotatably connected to the fixing sleeve 26. This connection allows the fixing claw 35 to rotate around the fixing sleeve 26 as an axis, achieving different working states. When the substrate 21 needs to be installed, the fixing claw 35 is first retracted inward. At this time, the fixing buckle 36 on the fixing block 32 can smoothly engage into the first slot 37 of the fixing sleeve 26. The cooperation between the fixing buckle 36 and the first slot 37 temporarily keeps the fixing claw 35 in the retracted state, making it convenient for the operator to insert the fixing sleeve 26 on the substrate 21 into the fixing through hole 18 of the mounting bracket 13.

[0035] After the substrate 21 is initially positioned, the fixing claw 35 is rotated outward so that one end contacts the fixing block 32 and the other end contacts the mounting bracket 13. At this time, the pull rod 31 is pulled to move the fixing block 32. When the fixing block 32 moves to the appropriate position, the fixing buckle 36 disengages from the first slot 37 and engages in the second slot 38. The fixing buckle 36 is engaged in the second slot 38 to prevent the fixing claw 35 from rotating accidentally, ensuring that the fixing claw 35 is stably pressed between the fixing block 32 and the mounting bracket 13, forming an additional clamping force on the substrate 21, further firmly fixing the substrate 21 to the mounting bracket 13, effectively preventing the substrate 21 from loosening during use, and ensuring the structural stability of the LED display module during operation.

[0036] During the operation of the LED display module, the multiple sets of heat dissipation holes 27 on the substrate 21 play a crucial role in heat dissipation. These heat dissipation holes 27 are hexagonal in shape and arranged in multiple sets to form a honeycomb structure. This layout increases the surface area of ​​the substrate 21, allowing the heat on the substrate 21 to exchange with the outside air more quickly. The heat generated when the LED display is working can be quickly transferred to the outside of the module through these heat dissipation holes 27. At the same time, the mounting frame 14 has multiple sets of heat dissipation grooves 19 corresponding to the heat dissipation holes 27. The heat dissipation grooves 19 are connected vertically to the heat dissipation holes 27, further expanding the heat dissipation path, allowing air to circulate more smoothly, accelerating heat dissipation, effectively reducing the operating temperature of the substrate 21 and the display body 22, and ensuring the stable operation of the LED display module.

[0037] The sealing ring 28, located between the substrate 21 and the mounting frame 14, serves a protective function. A positioning groove 29 on the substrate 21 is used to hold the sealing ring 28. After the sealing ring 28 is engaged in the positioning groove 29, it contacts the opening surface of the mounting frame 14. In actual use, the sealing ring 28 can prevent external dust, moisture, and other impurities from entering the mounting grid, avoiding these impurities from affecting the normal operation of the electronic components on the substrate 21 and the display screen body 22, reducing the probability of malfunctions caused by external factors, and improving the dustproof and waterproof performance and lifespan of the LED display module.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
