Description

Technical Field

[0001] This invention relates to the technical field of LED displays, and more specifically to an LED display module that is easy to assemble. Background Technology

[0002] LED display modules, as the basic building blocks of LED displays, are widely used in outdoor advertising, stage backdrops, information dissemination, and other display scenarios. With the continuous expansion of LED display applications, increasingly higher demands are being placed on the assembly efficiency and ease of maintenance of these displays.

[0003] In existing technologies, LED display modules are typically assembled using screws or magnetic attachment. While screws provide a more secure connection, the assembly and disassembly process requires operators to use screwdrivers and other tools to tighten each screw individually or in large quantities. This is cumbersome, labor-intensive, and severely impacts the assembly efficiency and maintenance speed of the display screen.

[0004] Magnetic adsorption simplifies operation to some extent, eliminating the need for tools. However, the magnetic structure typically only provides adsorption force perpendicular to the module surface, offering weaker control over the module in the direction parallel to the surface. When subjected to external vibration or impact, the module is prone to displacement, affecting the display effect. Furthermore, disassembly using the same magnetic structure is difficult due to the tight fit between the modules, leaving little room for maneuver and potentially damaging the module frame or the LEDs.

[0005] Therefore, existing technologies suffer from problems such as low assembly efficiency and difficulty in disassembly and maintenance of LED display modules. Summary of the Invention

[0006] The main objective of this invention is to provide an LED display module that is easy to assemble, thereby solving the problems of cumbersome assembly, difficult disassembly, and insufficient connection stability of LED display modules in related technologies.

[0007] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0008] An easy-to-assemble LED display module includes a mounting frame and multiple display modules disposed within the mounting frame. The mounting frame is provided with a first limiting plate, a second limiting plate, and a drive component for moving both.

[0009] The display module includes a display panel and a limiting rod disposed on the display panel, and the limiting rod is provided with a limiting component; the limiting plate 2 is provided with a plurality of limiting holes that are adapted to the limiting rod;

[0010] When the limiting component is configured to be assembled, the limiting rod is inserted into the limiting hole and then prevented from retracting; the second limiting plate is moved to make the display module abut against the first limiting plate, thus completing the assembly of the display module;

[0011] A cover plate is provided on the side of the mounting frame away from the display module. Multiple reset components and elastic components are located on the cover plate corresponding to the limiting holes. The elastic components are configured to drive the limiting rod out of the limiting holes. During disassembly, the driving limiting plate moves away from the display module, pushing the target display module to move so that the reset components abut against the limiting components, thereby releasing the limitation components from restricting the limiting rod. The display module is then pushed out of the mounting frame by the action of the elastic components.

[0012] Specifically, the limiting component includes an elastic element and a limiting block. A receiving groove is provided on the limiting rod. The limiting block is slidably disposed in the receiving groove and the sliding direction is perpendicular to the extension direction of the limiting rod. The elastic element is disposed between the limiting rod and the limiting block to drive the limiting block away from the limiting rod. One side of the limiting block along the extension direction of the limiting rod is set as an inclined surface so that the limiting block can pass through the limiting hole.

[0013] Specifically, the reset assembly includes a trigger rod and a positioning element. The trigger rod corresponds to a limit block, and the positioning element corresponds to a receiving groove. The trigger rod abuts against the inclined surface of the limit block to press the limit block into the receiving groove, and the positioning element restricts the position of the limit block in the receiving groove.

[0014] Specifically, the positioning component includes an elastic element two and a baffle. A sliding groove one communicating with the receiving groove is provided on the limiting rod, and the baffle is slidably disposed in the sliding groove one. The elastic element two is disposed between the baffle and the limiting rod to drive the baffle to move toward the receiving groove, so as to limit the limiting block when the limiting block retracts into the receiving groove.

[0015] Specifically, the end face of the baffle is flush with the end face of the limiting rod so that the baffle can pass through the limiting hole.

[0016] Specifically, a second sliding groove communicating with the receiving groove is provided on one side of the limiting rod corresponding to the receiving groove; when the limiting rod moves toward the trigger rod, the trigger rod is slidably disposed in the second sliding groove so as to press the limiting block against the baffle and the receiving groove.

[0017] Specifically, the elastic component includes an elastic element three and a push block. The push block is slidably disposed on the cover plate and the sliding direction is the same as the extension direction of the limiting rod. The positions of the push block and the limiting rod correspond one-to-one. The elastic element three is disposed between the cover plate and the push block to drive the push block to move toward the limiting rod.

[0018] Specifically, the limiting plate has several through slots so that the limiting rod passes through the through slots and the display plate abuts against the limiting plate.

[0019] Specifically, an extension block is provided on the mounting frame, and a three-way groove is provided in the extension block to communicate with the interior of the mounting frame. An extension plate adapted to the three-way groove is provided on a first limiting plate and a second limiting plate, and the extension plate is slidably disposed in the three-way groove.

[0020] Specifically, the drive assembly includes two lead screws, both rotatably mounted within the slide groove three, with one end extending beyond the extension block; through holes adapted to the lead screws are provided on the extension plates of both the first and second limiting plates, and the extension plates are threadedly connected to the lead screws. The two lead screws correspond to the extension plates of the first and second limiting plates, respectively.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. By using the limit rod, limit hole and limit component together, during assembly, simply insert the limit rod into the limit hole and the limit component will automatically lock the limit rod to prevent it from coming out. Then, the drive component moves the limit plate to press the display module, which realizes the quick installation and stable fixation of the display module without the need for screws or other tools, which greatly improves the assembly efficiency.

[0023] 2. During disassembly, the limit plate is driven backward by the drive component, and the locking is released by the cooperation of the reset component and the limit component. At the same time, the elastic component automatically pushes the display module out of the mounting frame, making the disassembly process easy and effortless, without the need for manual prying, and effectively avoiding damage to the display module or LED beads during disassembly.

[0024] 3. By pushing the target display module to trigger the corresponding reset component, a single display module can be precisely disassembled without affecting other adjacent display modules, facilitating targeted maintenance and replacement. Attached Figure Description

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] Reference Figures 1 to 11 An easy-to-assemble LED display module includes a mounting frame 1, a display module 2, a first limiting plate 31, a second limiting plate 32, a driving component 4, a limiting component 5, a reset component 6, and an elastic component 7. The display module 2, the first limiting plate 31, and the second limiting plate 32 are sequentially arranged within the mounting frame 1.

[0046] The drive assembly 4 is used to drive the first limiting plate 31 and the second limiting plate 32 to move horizontally within the mounting frame 1. The first limiting plate 31 and the second limiting plate 32 cooperate to guide the installation of the display module 2 and cooperate with the limiting assembly 5 to fix the display module 2, thereby facilitating the assembly of the display module 2.

[0047] The reset component 6 is used to release the limiting component 5 from the display module 2 when it is being disassembled. It also works with the elastic component 7 to push the display module 2 out of the mounting frame 1, facilitating the disassembly of the display module 2.

[0048] Reference Figures 1 to 4 An extension block 12 is provided on the mounting frame 1, and the extension block 12 is fixedly installed on the side of the mounting frame 1. A groove 321 communicating with the interior of the mounting frame 1 is provided inside the extension block 12. Limiting plates 1 and 2 are adapted to the mounting frame 1, that is, limiting plates 1 and 2 are arranged parallel to each other within the mounting frame 1. An extension plate 33 is provided at the edge of the limiting plates 1 and 2. The extension plate 33 is adapted to the groove 321, that is, the extension plate 33 is slidably disposed within the groove 321, so that the limiting plates 1 and 2 32 can slide smoothly relative to the mounting frame 1. A guide rod 43 is fixedly installed within the groove 321 above the mounting frame 1. A guide hole adapted to the guide rod 43 is provided on the extension plate 33 within the groove 321, that is, the guide rod 43 passes through the guide hole.

[0049] In this embodiment, two extension blocks 12 are provided, and the two extension blocks 12 are respectively located on the upper and lower sides of the mounting frame 1. An extension plate 33 is provided on each of the two extension blocks 12 on both the first limiting plate 31 and the second limiting plate 32 to improve the stability of the movement of the first limiting plate 31 and the second limiting plate 32.

[0050] Reference Figures 1 to 5 The drive assembly 4 includes two lead screws 41. Both lead screws 41 are rotatably mounted within the slide groove 121. One end of each lead screw 41 extends to the outside of the front end of the extension block 12. A handwheel 42 is fixedly mounted at the end of the lead screw 41 outside the extension block 12, allowing the operator to drive the lead screw 41 to rotate via the handwheel 42. Through holes adapted to the lead screws 41 are provided on the extension plates 33 of both the first limiting plate 31 and the second limiting plate 32, and the extension plates 33 and the lead screws are threaded together. The two lead screws 41 correspond to the extension plates 33 on the first limiting plate 31 and the second limiting plate 32, respectively. In this embodiment, the lead screws 41 are mounted in the slide groove 121 located below the mounting frame 1.

[0051] By rotating the lead screw 41, the thread transmission principle is utilized to precisely control the movement of the first limit plate 31 and the second limit plate 32 along the direction of the third slide groove 121.

[0052] Reference Figures 2 to 6 The display module 2 includes a display panel 21 and a limiting rod 22 located on the back of the display panel 21. The front surface of the display panel 21 faces the outside of the mounting frame 1. An array of LED beads is distributed on the front surface of the display panel 21. The limiting rod 22 is set perpendicular to the display panel 21 to cooperate with the second limiting plate 32 and the first limiting plate 31 to achieve the positioning and fixation of the display module 2. The second limiting plate 32 has multiple limiting holes 321 adapted to the limiting rod 22, through which the limiting rod 22 can pass. The first limiting plate 31 has multiple through slots 311, the positions of which correspond to the limiting holes 321 and the limiting rod 22, so that the limiting rod 22 can pass through the through slots 311. Finally, the back of the display panel 21 abuts against the side of the first limiting plate 31 closest to the display panel 21.

[0053] The end of the limiting rod 22 away from the display panel 21 is chamfered to facilitate the insertion of the limiting rod 22 into the limiting hole 321.

[0054] Reference Figures 5 to 8 A limiting component 5 is disposed on the limiting rod 22. The limiting component 5 is configured to prevent the limiting rod 22 from retracting out of the limiting hole 321 after it is inserted into the limiting hole 321 during assembly. The limiting component 5 includes an elastic element 51 and a limiting block 52. A receiving groove 221 is formed on the limiting rod 22. The limiting block 52 is slidably disposed within the receiving groove 221, and its sliding direction is perpendicular to the extension direction of the limiting rod 22. The elastic element 51 is disposed between the limiting rod 22 and the limiting block 52, specifically between the bottom of the receiving groove 221 and the limiting block 52. This drives the limiting block 52 away from the limiting rod 22, i.e., the limiting block 52 extends out of the receiving groove 221. One side of the limiting block 52 along the extension direction of the extending rod is configured as an inclined surface. In this embodiment, the elastic element 51 is configured as a spring.

[0055] During assembly, the operator pushes the display module 2 into the mounting frame 1. When the limiting rod 22 is inserted into the corresponding limiting hole 321, the wall of the limiting hole 321 presses against the inclined surface of the limiting block 52. Under the action of the inclined surface, the pressing force generates a component force perpendicular to the inclined surface to overcome the elastic force of the elastic element 51. The limiting block 52 is pressed into the receiving groove 221 so that the limiting block 52 can pass smoothly through the limiting hole 321. After the limiting block 52 has completely passed through the limiting hole 321, the pressing force disappears, and under the action of the elastic element 51, the limiting block 52 automatically pops out of the receiving groove 221. At this time, the limiting block 52 is stuck on the side surface of the limiting plate 32 facing away from the display panel 21, forming an inverted structure to prevent the limiting rod 22 from exiting. This achieves initial locking of the display module 2, preventing the previously assembled display module 2 from shifting and causing the display module 2 to move out of the mounting frame 1 when assembling other display modules 2. In this implementation, the number of display modules 2 is set to 9.

[0056] After all display modules 2 are installed into the mounting frame 1, the lead screw 41 is rotated to drive the second limiting plate 32 to move away from the first limiting plate 31. That is, the second limiting plate 32 drives the display panel 21 to move towards the first limiting plate 31 through the limiting block 52 until the display panel 21 abuts against the first limiting plate 31. The display panel 21 is positioned by the first limiting plate 31 and the second limiting plate 32 to achieve a stable assembly of the display modules 2.

[0057] Reference Figures 3 to 6 A cover plate 13 is fixedly installed on the side of the mounting frame 1 away from the display module 2. The cover plate 13 is located on the side of the limiting plate 22 away from the display panel 21. In this embodiment, the reset component 6 and the elastic component 7 are provided with multiple corresponding limiting holes 321, specifically nine.

[0058] The reset assembly 6 includes a trigger rod 61 and a positioning element 62. The trigger rod 61 is fixedly mounted on the cover plate 13 on the side facing the display panel 21. The trigger rod 61 corresponds one-to-one with the limiting block 52. That is, when the limiting rod 22 moves the limiting block 52 toward the trigger rod 61, the trigger rod 61 abuts against the inclined surface of the limiting block 52, pushing the limiting block 52 back into the receiving groove 221. The positioning element 62 corresponds one-to-one with the receiving groove 221, thus limiting the position of the limiting block 52 when it retracts into the receiving groove 221.

[0059] Reference Figure 7 and Figure 8 The positioning element 62 includes an elastic element 63 and a baffle 64. A groove 222 communicating with the receiving groove 221 is formed on the limiting rod 22. The baffle 64 is slidably disposed within the groove 222. The elastic element 63 is disposed between the baffle 64 and the limiting rod 22, and is used to drive the baffle 64 to move towards the receiving groove 221. When the limiting block 52 is extended out of the receiving groove 221, the baffle 64 abuts against the side of the limiting block 52, and the elastic element 63 is in a compressed state. When the limiting block 52 retracts into the receiving groove 221, that is, when the limiting block 52 no longer blocks the baffle 64, under the action of the elastic element 63, the baffle 64 extends to the receiving groove 221 to limit the limiting block 52. This prevents the limiting block 52 from extending out of the receiving groove 221 after the trigger rod 61 disengages from the limiting block 52. To ensure that the limiting rod 22 can pass smoothly through the limiting hole 321, the end face of the baffle 64 is flush with the corresponding end face of the limiting rod 22, so that the baffle 64 can pass over the limiting hole 321. In this embodiment, the elastic element 63 is set as a spring.

[0060] A second sliding groove 223, communicating with the receiving groove 221, is also provided on one side of the limiting rod 22. The bottom of the second sliding groove 223 is lower than the bottom of the first sliding groove 222. When the trigger rod 61 abuts against the limiting block 52, the trigger rod 61 slides within the second sliding groove 223, thereby pressing the limiting block 52 into the receiving groove 221 at a position between the baffle 64 and the receiving groove 221.

[0061] Reference Figure 5 and Figure 6 The elastic component 7 includes an elastic element 71 and a push block 72. A limiting groove 131 is formed on the cover plate 13, and the push block 72 is slidably disposed within the limiting groove 131. The sliding direction of the push block 72 is the same as the sliding direction of the limiting plate 32. Multiple push blocks 72 correspond one-to-one with multiple limiting rods 22. The elastic element 71 is disposed between the cover plate 13 and the push block 72, and is used to drive the push block 72 to move toward the limiting rod 22. In the assembled state, the position of the display module 2 is fixed, the push block 72 is compressed between the cover plate 13 and the end of the limiting rod 22, and the elastic element 71 is in a compressed state so that when the limiting block 52 no longer restricts the position of the limiting rod 22 relative to the limiting plate 32, the elastic element 71 pushes the limiting rod 22 to move the display plate 21 out of the mounting frame 1, which is convenient for the operator to disassemble. In this embodiment, the elastic element 71 is set as a spring.

[0062] Specific work process:

[0063] Reference Figure 9 Preliminary assembly:

[0064] When installing display module 2, adjust the second limiting plate 32 to a position close to the first limiting plate 31.

[0065] The operator inserts the limiting rod 22 into the corresponding limiting hole 321 until the limiting block 52 moves to the side of the limiting block 52 away from the limiting plate 31. The limiting block 52 restricts the limiting rod 22 to prevent the previously installed display module 2 from detaching from the limiting hole 321 when installing other display modules 2.

[0066] Reference Figure 10 Assembly complete:

[0067] After all display modules 2 are installed, drive the second limiting plate 32 away from the first limiting plate 31 until the display plate 21 abuts against the first limiting plate 31. This ensures the stable installation of the display modules 2. During this process, the end face of the limiting rod 22 abuts against the push block 72, and the elastic element 71 is in a compressed state.

[0068] Reference Figure 11 Disassemble display module 2:

[0069] When disassembling display module 2, drive limiting plate 31 to move towards limiting plate 32, so that limiting plate 31 disengages from display panel 21, allowing limiting rod 22 to move towards push block 72. At this time, the operator presses down on the display panel 21 to be disassembled. Limiting rod 22 moves towards trigger rod 61, so that trigger rod 61 presses against limiting block 52, pressing limiting block 52 into receiving groove 221, and limiting limiting block 52 by baffle 64. Under the action of elastic element 71, push the corresponding limiting rod 22 to move display panel 21 out of mounting frame 1, and the operator can then remove display module 2. Repeating the above operation can disassemble multiple display modules 2.

[0070] The insertion locking function is achieved by limiting component 5, and the pressing unlock function is achieved by the cooperation of reset component 6 and limiting component 5. Combined with the automatic ejection of elastic component 7, the disassembly and assembly process of LED display module is greatly simplified, solving the problems of cumbersome assembly and difficult disassembly in the existing technology.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
