Description

Technical Field

[0001] This application relates to the field of display module installation technology, and in particular to a display module connection device. Background Technology

[0002] A display module, also known as an LED display module or simply a unit board, is the main component of an LED display screen. It consists of LED light-emitting diodes, driving circuits, driving ICs, and plastic components. Display module connections are one of the commonly used components in modern electronic devices, especially in large-scale display devices. It is necessary to splice various display modules together to present a super-large LED display screen to meet the growing needs of people's development. Many LED displays on the market are composed of multiple display modules spliced ​​together, that is, a large screen is formed by splicing multiple module units together.

[0003] The existing technology still has the following problems:

[0004] 1. When splicing display modules, it is necessary to install frame strips of the specified dimensions on the outer frame box to facilitate the uniform fixing of the display modules inside the outer frame box. The existing frame is installed by measuring manually, which affects the connection efficiency of the display modules.

[0005] 2. The quality of the splicing effect of each display module directly affects the display effect of the entire LED display screen. Unevenness at the connection points between LED display modules prevents the LED display screen from being installed flat and seamlessly on the outer frame, affecting the display effect of the LED display modules. Furthermore, gaps can also affect the aesthetics of the LED display screen.

[0006] 3. After the display module is installed, it is difficult to see the flatness of the display module by visual inspection alone. When it is found that there is a difference in the flatness of the module components after installation, a lot of time is required for adjustment and maintenance, which affects the connection efficiency of the display module.

[0020] 2. By employing an adjustment component, the problem of unevenness at the connection points between LED display modules, which directly affects the overall display effect of the LED screen, is effectively solved.

[0039] The manual measurement and installation of the frame affects the connection efficiency of the display module. This invention uses a mounting bracket assembly to quickly and evenly distribute the frame strips on the outer frame box, avoiding uneven distribution and wasted time caused by manual measurement. For unevenness at the connection points between LED display modules, this invention uses an adjustment component to adjust the height and tilt of the installed display module, ensuring that the contact points between the display modules are aligned. For the flatness of the display module, which is difficult to observe visually, this invention uses a detection component to detect whether the display module is flat after connection, facilitating quick adjustment of the display module.

[0040] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0041] Example 1

[0042] Please see Figure 1 and Figure 15 As shown, a display module connection device includes an outer frame box 1, an inner cavity of which is provided with a mounting bracket assembly 2, an adjustment assembly 3 fixedly mounted on the outer surface of the mounting bracket assembly 2, a storage groove 4 formed on the upper surface of the outer frame box 1, a cover 5 slidably connected to the upper surface of the storage groove 4, a third sliding groove 6 formed on the outer surface of the outer frame box 1, and a detection assembly 7 slidably connected to the inner cavity of the third sliding groove 6. The mounting bracket assembly 2 is used to quickly divide the outer frame box 1 into equal parts, the adjustment assembly 3 is used to adjust the height and angle between the display modules, the storage groove 4 is used to store the detection mechanism 75, the cover 5 is used to cover the storage groove 4, and the detection assembly 7 slides on the third sliding groove 6 to perform flatness detection on the display modules.

[0043] Please see Figure 2 , Figure 3 and Figure 4 As shown, the mounting bracket assembly 2 includes a limiting frame 21. A first sliding groove 22 is formed on the outer surface of the limiting frame 21. A first slider 23 is slidably connected to the inner cavity of the first sliding groove 22. An adjusting plate 24 is fixedly installed at the bottom end of the first slider 23. An adjusting groove 25 is formed on the outer surface of the adjusting plate 24. A sliding rod 26 is slidably connected to the inner cavity of the adjusting groove 25. A first frame strip 27 is fixedly installed on the outer surface of the sliding rod 26. A second sliding groove 28 is formed in the middle of the first frame strip 27. An adjusting mechanism 29 is slidably connected to the inner cavity of the second sliding groove 28. A second threaded rod 210 is sleeved inside the inner cavity of the first slider 23. A limiting block 211 is sleeved on the outer surface of the second threaded rod 210. The limiting frame 21 and the outer frame box 1 are fixedly connected. The limiting block 211 and the outer frame box 1 are fixedly connected. The second threaded rod 210 and the limiting block 211 are rotatably connected. The first slider 23 and the second threaded rod 210 are connected by threads, facilitating the connection of the second threaded rod. When 210 rotates, it can drive the first slider 23 to move. There are nine adjustment slots 25, and the adjustment slots 25 are symmetrically distributed about the middle part of the adjustment plate 24. The distance between adjacent adjustment slots 25 decreases uniformly from top to bottom. When adjusting the distance between the first frame bars 27, the first slider 23 moves in the inner cavity of the first slide groove 22 by rotating the second threaded rod 210. The movement of the first slider 23 drives the adjustment plate 24 to move. The movement of the adjustment plate 24 drives the adjustment slot 25 to drive the slide rod 26 to move. The movement of the slide rod 26 drives the first frame bars 27 to move. The movement of the first frame bars 27 changes the distance between the first frame bars 27, quickly and evenly separating the first frame bars 27. The second frame bars 291 slide in the inner cavity of the second slide groove 28, and the second frame bars 291 are evenly separated, so that the first frame bars 27 and the second frame bars 291 form a fixed frame, which facilitates the quick connection of the display module.

[0044] Please see Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the adjusting mechanism 29 includes a second frame bar 291. A connecting rod 292 is fixedly installed on the middle part of the outer surface of the second frame bar 291. A connector 293 is fixedly installed on the outer surface of the second frame bar 291. An adjusting groove 294 is formed on the outer surface of the connector 293. A second slider 295 is slidably connected to the inner cavity of the adjusting groove 294. A first threaded rod 296 is provided in the inner cavity of the connector 293. A communicating groove 297 is formed on the outer surface of the first frame bar 27, and the communicating groove 297 is only formed on the middle part of the first frame bar 27. A limiting mechanism 298 is fixedly installed on the outer surface of the second frame bar 291, and the limiting mechanism 298 is only installed on the uppermost second frame bar 291. First inserts are formed on both sides of the communicating groove 297. Hole 299, bottom end of connector 293 is fixedly connected to second frame bar 291, connecting rod 292 and adjusting groove 294 are slidably connected, first threaded rod 296 and connector 293 are threadedly connected, limiting mechanism 298 includes first connecting block 2981, fixedly connected to the uppermost second frame bar 291, elastic rod 2982 is slidably connected to the inner cavity of first connecting block 2981, first connecting plate 2983 is fixedly installed on the outer surface of elastic rod 2982, first spring 2984 is sleeved on the outer surface of elastic rod 2982, first spring 2984 is located between elastic rod 2982 and inner wall of first connecting block 2981, first insert rod 2985 is fixedly installed at both ends of first connecting plate 2983, first insert rod 2985 and first... One insertion hole 299 is engaged, and the connecting parts 293 slide in pairs. By pulling the first connecting plate 2983, the first insertion rod 2985 is disengaged from the first insertion hole 299. At this time, the first connecting block 2981 is moved, causing the uppermost second frame bar 291 to move. The movement of the second frame bar 291 drives the connecting rod 292 to move. The connecting rod 292 slides in the adjusting groove 294. When the connecting rod 292 contacts the second slider 295, it drives the connecting part 293 to move as a whole. Under the action of the connecting part 293, the second frame bars 291 are evenly distributed. When the first connecting plate 2983 is released at the appropriate position, the first insertion rod 2985 is engaged with the first insertion hole 299 again under the elastic force of the first spring 2984. At this time, the second slider 295 is evenly distributed. The connecting rod 292 is in close contact with the second frame strip 291 to ensure equal spacing. The position of the first threaded rod 296 within the adjusting groove 294 can be changed by rotating it. This change in position alters the contact position between the connecting rod 292 and the second slider 295 during the movement of the connector 293. In other words, the spacing between the second frame strips 291 can be fine-tuned according to actual conditions. Combined with the adjustment of the first frame strip 27, the first frame strip 27 and the second frame strip 291 are fixedly welded together after adjustment to improve the stability of the resulting frame. The frame formed between the first frame strip 27 and the second frame strip 291 is used to fix the adjusting assembly 3, and then the display module is fixedly spliced ​​onto the adjusting assembly 3.This creates a super-large screen display.

[0045] Example 2

[0046] Please see Figure 10 and Figure 11 As shown, the adjusting assembly 3 includes a fixed plate 31. A first fixed block 32 is fixedly mounted on the outer surface of the fixed plate 31. A third slider 33 is slidably connected to the inner cavity of the first fixed block 32. An adjusting rod mechanism 34 is provided in the inner cavity of the third slider 33. A first movable strip 35 is movably connected to both sides of the third slider 33. A second connecting block 36 is movably connected to the end of the first movable strip 35 away from the third slider 33. A rotating mechanism 37 is fixedly mounted on the outer surface of the second connecting block 36. Adjusting mechanisms 38 are provided at both ends of the fixed plate 31. A third fixed block 39 is fixedly mounted on both sides of the fixed plate 31. A second movable strip 310 is rotatably connected to the inner cavity of the third fixed block 39. There are two second connecting blocks 36, and the inner cavity of the second connecting block 36 is provided with a movable long groove 311. There are two first fixed blocks 32, which are symmetrically distributed about the middle part of the fixed plate 31. The second movable strip 310 is away from the third fixed block 32. One end of the fixed block 39 is movably connected to the first movable strip 35. The adjusting mechanism 38 is used to fix the first frame strip 27 with bolts. The display module is used to fix the rotating mechanism 37. The left and right tilt angles of the rotating mechanism 37 are adjusted by rotating the adjusting rod mechanism 34. The rotation of the adjusting rod mechanism 34 drives the third slider 33 to move in the inner cavity of the first fixed block 32. The movement of the first fixed block 32 causes the angle of the first movable strip 35 to change, thereby changing the distance between the second connecting block 36 and the fixed plate 31, that is, adjusting the distance of the rotating mechanism 37. The second connecting block 36 on one side can be adjusted by rotating the adjusting rod mechanism 34, or the second connecting blocks 36 on both sides can be adjusted simultaneously. The movable long groove 311 facilitates the movement of the first movable strip 35 in the movable long groove 311 when adjusting only one of the second connecting blocks 36, that is, the first movable strip 35 will not lock when adjusting only one of the second connecting blocks 36.

[0047] Please see Figure 11As shown, the adjusting rod mechanism 34 includes a third threaded rod 341. A slot 342 is provided on one side of the third threaded rod 341. A retaining rod 344 is inserted into the inner cavity of the slot 342. A fourth threaded rod 343 is sleeved on the outer surface of the retaining rod 344. Both the third threaded rod 341 and the fourth threaded rod 343 are threadedly connected to the third slider 33. Both the third threaded rod 341 and the fourth threaded rod 343 are rotatably connected to the first fixed block 32. The third threaded rod 341 and the fourth threaded rod 343 are symmetrically distributed about the middle part of the fixed plate 31. By rotating the third threaded rod 341 and the fourth threaded rod 343 respectively, the adjustment mechanism can be adjusted. 41 and the fourth threaded rod 343 can adjust one of the second connecting blocks 36 individually. At this time, the angle of one end of the rotating mechanism 37 changes, thereby changing the angle of one end of the display module. By inserting the locking rod 344 into the inner cavity of the locking slot 342, the two second connecting blocks 36 can be adjusted simultaneously. That is, by rotating the adjusting rod mechanism 34, the height of the rotating mechanism 37 will change, and the angles on both sides of the rotating mechanism 37 can be adjusted at the same time. This makes it easy for all the display modules to be flush when connected, forming a neat large screen.

[0048] Please see Figure 12 , Figure 13 and Figure 14As shown, the rotating mechanism 37 includes a second connecting plate 371. Second fixing blocks 372 are fixedly installed at both ends of the second connecting plate 371. A rotating rod 373 is rotatably connected to the inner cavity of the second fixing block 372. A limit groove 374 is formed in the middle of the rotating rod 373. An adjusting head 375 is fixedly installed at one end of the rotating rod 373. A second insertion hole 376 is formed on the outer surface of the second fixing block 372 near the adjusting head 375. The adjusting head 375 slides near the outer surface of the rotating rod 373. A second insertion rod 377 is connected, and the second insertion rod 377 is inserted into the second insertion hole 376. A sleeve 378 is sleeved on the outer surface of the rotating rod 373. A limit plate 379 is fixedly installed in the inner cavity of the sleeve 378. A placement plate 3710 is fixedly installed on the outer surface of the sleeve 378. A second spring is provided between the adjusting head 375 and the second insertion rod 377. By pressing the second insertion rod 377, the second spring is compressed. At this time, the second insertion rod 377 is partially pressed into the inner cavity of the adjusting head 375. 77 and the second insertion hole 376 are disengaged. The adjusting head 375 is rotated to drive the rotating rod 373 to rotate. The rotation of the rotating rod 373 drives the limiting plate 379 in the inner cavity of the limiting groove 374 to rotate. The rotation of the limiting plate 379 drives the sleeve 378 to rotate. The rotation of the sleeve 378 drives the placement plate 3710 to rotate, thereby driving the display module fixed on the placement plate 3710 to rotate. Holes can be made in the placement plate 3710, and the display module can be fixed to the placement plate 3710 with bolts or by welding. When the appropriate position is reached, the second insertion rod 377 and the second insertion hole 376 are re-inserted. At this time, the placement plate 3710 remains relatively stable. With the adjustment rod mechanism 34, the overall adjustment of the rotating mechanism 37 is made so that the display module on the placement plate 3710 can be adjusted in any direction, so that all display modules are finally presented on the same plane, and the spliced ​​display modules present a clear and good picture.

[0049] Please see Figure 3 , Figure 10 and Figure 11As shown, the adjustment mechanism 38 includes a fixed frame 381 located at both ends of the fixed plate 31. A third insert rod 382 is slidably connected to the inner cavity of the fixed frame 381. A third spring 383 is sleeved on the outer surface of the third insert rod 382. A movable plate 384 is slidably connected to the inner cavity of the bottom end of the fixed plate 31. A third insertion hole 385 is formed on the outer surface of the movable plate 384. The third insert rod 382 and the third insertion hole 385 are inserted into each other. When fixing the adjustment mechanism 38 and the first frame bar 27, the movable plate 384 and the first frame bar 27 are fixed with bolts. After the spacing of the first frame bar 27 is adjusted, the spacing of the movable plate 384 is adjusted accordingly. The movable plate 384 is adapted to the spacing of the first frame strip 27. The third spring 383 is extended and retracted by pulling the third insert rod 382. At this time, the third insert rod 382 and the third insert hole 385 are disengaged. The movable plate 384 is moved to the position inside the fixed plate 31 so that the two movable plates 384 at both ends of the fixed plate 31 can extend and retract. When the appropriate position is reached, the third insert rod 382 is released, and the third insert rod 382 and the third insert hole 385 are re-inserted to maintain the stability of the movable plate 384 inside the fixed plate 31. Multiple adjustment components 3 are installed on the first frame strip 27 in sequence, and then the display module is fixed on the adjustment components 3 to form a spliced ​​large screen.

[0050] Please see Figure 1 , Figure 15 and Figure 16As shown, the detection assembly 7 includes a fourth slider 71, with movable frames 72 fixedly mounted at both ends of the fourth slider 71. The movable frames 72 are slidably connected to the third slide groove 6. A movable groove 73 is provided in the middle of the fourth slider 71. A movable block 74 is slidably connected to the inner cavity of the movable groove 73. A detection mechanism 75 is provided in the inner cavity of the movable block 74. The detection mechanism 75 includes a detection frame 751. A movable rod 752 is fixedly mounted on the outer surface of the detection frame 751. A movable strip 753 is slidably connected to the inner cavity of the detection frame 751. Both ends of the test frame 751 are fixedly installed with inclined blocks 754. Pressure rods 755 are slidably connected to both ends of the test frame 751. A pressure block 756 is provided in the middle of the pressure rod 755. The inclined blocks 754 and the pressure block 756 are in contact. A test disc 757 is fixedly installed at one end of the pressure rod 755. A fourth spring 758 is sleeved on the outer surface of the pressure rod 755. The fourth spring 758 is located between the test frame 751 and the test disc 757. A movable rod 752 and a moving block 74 are sleeved together. A test block is fixedly installed on the outer surface of the pressure rod 755. The test block is flush with the outer surface of the test frame 751. The moving frame 72 slides within the inner cavity of the third slide groove 6, and the moving block 74 slides within the inner cavity of the moving groove 73, allowing the test mechanism 75 to move to any position on the outer surface of the outer frame box 1. At this time, the test mechanism 75 performs flatness testing on the connected display modules. The two test discs 757 contact the two adjacent display modules respectively. When the display module is uneven, the force of the fourth spring 758 causes the pressure rod 755 to move. At this time, the pressure block 7 within the inner cavity of the pressure rod 755... 56. Press the inclined block 754 and observe the position of the detection block on the pressure rod 755. If the two pressure rods 755 are uneven, it indicates that there is an unevenness between the display modules. Adjust the display modules by adjusting the component 3 until all the display modules fall on a horizontal plane to improve the connection effect of the display modules. At the same time, the movable rod 752 and the moving block 74 are movably connected to ensure that the detection plate 757 can make close contact with the display module. The detection mechanism 75 can be taken out and stored in the storage slot 4.

[0051] In summary, the mounting bracket assembly 2 quickly divides the outer frame box 1 into equal parts; the adjusting assembly 3 is used to adjust the height and angle between the display modules; the storage slot 4 is used to store the detection mechanism 75; the cover 5 is used to cover the storage slot 4; the detection assembly 7 slides on the third slide 6 to perform flatness detection on the display modules; when adjusting the spacing of the first frame strips 27, the spacing between the first frame strips 27 changes by rotating the second threaded rod 210, quickly and evenly separating the first frame strips 27; and the second frame strip 291 is located in the second slide 28. The inner cavity slides, evenly separating the second frame strip 291, so that the first frame strip 27 and the second frame strip 291 form a fixed frame, facilitating the quick connection of the display module. The left and right tilt angles of the rotating mechanism 37 can be adjusted by rotating the adjusting rod mechanism 34. One of the second connecting blocks 36 can be adjusted individually by rotating the third threaded rod 341 and the fourth threaded rod 343 respectively. Both second connecting blocks 36 can be adjusted simultaneously by inserting the locking rod 344 into the inner cavity of the locking slot 342. The second spring is retracted by pressing the second insert rod 377. At this time, the second insert rod 377 part The second insertion rod 377 and the second insertion hole 376 are disengaged from the inner cavity of the adjusting head 375. Rotating the adjusting head 375 causes the placement plate 3710 to rotate, thereby driving the display module fixed on the placement plate 3710 to rotate. When fixing the adjusting mechanism 38 and the first frame bar 27, the moving plate 384 and the first frame bar 27 are fixed with bolts. After the spacing of the first frame bar 27 is adjusted, the spacing of the moving plate 384 is adjusted to adapt to the spacing of the first frame bar 27. The moving frame 72 slides in the inner cavity of the third slide groove 6, and the moving block 74 moves in the moving groove. The sliding of the inner cavity of 73 allows the detection mechanism 75 to move at any position on the outer surface of the outer frame box 1. At this time, the flatness of the connected display module is detected by the detection mechanism 75. The two detection disks 757 contact the two adjacent display modules respectively. When the display module is not flat, the pressure rod 755 moves under the elastic force of the fourth spring 758. At this time, the pressure block 756 in the inner cavity of the pressure rod 755 squeezes the inclined block 754. Observe whether the position of the detection block on the pressure rod 755 changes. If the detection block moves, the display modules are not flat and need to be adjusted by the adjustment component 3.
