Description

Technical Field

[0001] This invention relates to the field of display device technology, specifically to a MINILED small-pitch dot matrix display device. Background Technology

[0002] Dot matrix display devices are display devices that use a large number of tiny light-emitting units arranged in rows and columns to form a dot matrix. The images and text are displayed by switching on or adjusting the brightness of individual units. The core of the display is to achieve information display by driving the dot matrix units in an orderly manner. It has the characteristics of high brightness, large size adaptability and splicing. It is widely used in commercial large screens, outdoor advertising screens and monitoring screens. In order to improve the clarity and use effect of dot matrix display, MINILED small pitch dot matrix display devices are needed.

[0003] MiniLED small-pitch dot matrix display devices are display devices that use 50-200μm MiniLED lamp beads, densely arranged into a dot matrix with a dot pitch of P1.0 to P2.0. They are packaged in SMD and IMD forms, and the on / off state and brightness of the lamp beads are controlled by the driving circuit. They have the advantages of high brightness and high contrast, can achieve fine image quality, and are suitable for ultra-large screens of 110 inches and above and professional scenarios, such as large monitoring screens and medical imaging displays.

[0004] Currently available MINILED small-pitch dot matrix display devices consist of display modules and mounting frames. During use, they are assembled using a splicing structure to facilitate the combination and installation of multiple units. To improve connection stability, existing technologies use clips and slots for initial fixation. At the same time, to enhance overall rigidity, existing technologies use a fixing method of metal frames and bolts to reinforce the splicing points. However, this method makes it difficult to achieve quick disassembly and precise alignment, which affects the maintenance efficiency of the device and thus reduces its reliability. Summary of the Invention

[0005] The purpose of this invention is to provide a MINILED small-pitch dot matrix display device, which solves the problem of the difficulty in achieving rapid disassembly and precise alignment of MINILED small-pitch dot matrix display devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A MINILED small-pitch dot matrix display device includes a display, a lamp board fixedly connected to the inner side of the display, a mounting plate fixedly connected to the rear side of the display, an assembly mechanism provided on the inner side of the lamp board, the assembly mechanism being able to easily assemble multiple devices, a mounting mechanism provided on the inner side of the display, the mounting mechanism being able to easily install the devices, and a heat dissipation mechanism provided inside the lamp board, the heat dissipation mechanism being able to easily improve the heat dissipation effect of the device.

[0008] The assembly mechanism includes a bidirectional threaded rod, which is rotatably connected to the inner side of the lamp plate. A protective plate is fixedly connected to the rear side of the mounting plate. A threaded post is fixedly connected to the upper side of the bidirectional threaded rod, and a threaded cover is fixedly connected to the lower side of the bidirectional threaded rod. A lifting plate is threadedly connected to both the upper and lower outer sides of the bidirectional threaded rod. A rotating plate is rotatably connected to both the left and right sides of the lifting plate. A push plate is rotatably connected to the outer side of the rotating plate. A slot block is fixedly connected to the outer side of the left push plate, and a plug block is fixedly connected to the outer side of the right push plate.

[0009] With the above technical solution, rotating the bidirectional threaded rod can drive the threaded column and the threaded cover to rotate. When multiple devices are stacked up and down, they are assembled up and down through the threaded connection between the two. At the same time, the rotation of the bidirectional threaded rod drives the lifting plate to move up and down, pushes the rotating plate to rotate, and makes the push plate move left and right along the mounting plate. Its plug block engages with the slot block, which facilitates the fixation of the left and right devices.

[0010] Preferably, the mounting mechanism includes a bidirectional threaded rod II, which is rotatably connected to the inner center of the display. Lifting plates II are threadedly connected to the upper and lower outer sides of the bidirectional threaded rod II. Multiple connecting brackets are fixedly connected to the outer sides of the lifting plates II. A rack is fixedly connected to the outer sides of the connecting brackets. Circular gears are rotatably connected to the inner perimeter of the display, meshing with the rack. Threaded posts II are fixedly connected to the outer sides of the circular gears. A mounting block is threadedly connected to the outer sides of the threaded posts II. An operating component is provided on the outer wall of the display.

[0011] Through the above technical solution, rotating the bidirectional threaded rod II can drive the lifting plate II to move up and down, thereby linking the connecting frame and rack on it to move synchronously. The movement of the rack will drive the meshing circular gear to rotate, causing the threaded rod II to rotate accordingly, pushing the mounting block to move along the protective plate, thus facilitating the installation and fixing of the device.

[0012] Preferably, the heat dissipation mechanism includes a motor and a filter belt. Multiple motors are respectively fixedly connected to the left and right sides of the outer side of the mounting plate. The output end of the motor passes through the mounting plate and is fixedly connected to a rotating disk. A bevel gear is fixedly connected to the outer side of the rotating disk. Fan plates are rotatably connected to the left and right sides of the inside of the display. A bevel gear is fixedly connected to the outer side of the fan plate. The bevel gear and the bevel gear mesh with each other. Multiple rotating wheels are rotatably connected to the middle of the inner side of the mounting plate. The rotating wheels are connected to the rotating disk through the filter belt. A positioning component is provided on the outer side of the mounting plate.

[0013] Through the above technical solution, the starting motor drives the rotating disk to rotate, causing the bevel gear on it to rotate, which in turn drives the meshing bevel gear to rotate, causing the fan plate to rotate and generate airflow to dissipate heat from the device. At the same time, the rotating disk drives the filter belt through the rotating wheel, which can intercept impurities in the airflow and discharge them during the transmission.

[0014] Preferably, the assembly mechanism further includes guide rods, two of which are fixedly connected to the left and right sides inside the mounting plate, and the guide rods are slidably connected to the protective plate.

[0015] The above technical solution improves the stability of the protective plate during movement by using guide rods.

[0016] Preferably, the assembly mechanism further includes brackets, with multiple brackets fixedly connected to the left and right sides of the mounting plate, and the outer side of the brackets fixedly connected to the display.

[0017] The above technical solution improves the stability of the monitor by using a bracket.

[0018] Preferably, the mounting mechanism further includes a knob, which is rotatably connected to the top of the display, and the bottom of the knob passes through the display and is fixedly connected to a bidirectional threaded rod.

[0019] The above technical solution allows the bidirectional threaded rod to rotate by turning the knob.

[0020] Preferably, the operating component includes handles, and a plurality of handles are respectively fixedly connected to the outer perimeter of the display, with a protective sleeve fixedly connected to the outer side of the handle.

[0021] The above technical solution makes it easy to hold and carry the device through the handle and protective sleeve.

[0022] Preferably, the mounting mechanism further includes a sliding plate, wherein multiple sliding plates are fixedly connected to the outer perimeter of multiple mounting blocks, and the sliding plates are slidably connected to the protective plate.

[0023] The above technical solution improves the stability of the protective plate during movement by using a skateboard.

[0024] Preferably, the heat dissipation mechanism includes a second rotating disk, and the two second rotating disks are respectively rotatably connected to the left and right ends inside the mounting plate. The first rotating disk is connected to the second rotating disk via a filter belt.

[0025] By employing the above technical solution, the positioning of the filter belt by the rotating disc two can improve the transmission effect of the rotating disc one.

[0026] Preferably, the positioning component includes positioning blocks, and multiple positioning blocks are respectively fixedly connected to the left and right sides of the two mounting plates, with positioning holes provided on the inner side of the positioning blocks.

[0027] The above technical solution allows for the installation and fixation of the device by inserting a threaded component into the positioning hole.

[0028] In summary, the present invention has at least one of the following beneficial technical effects:

[0029] 1. This invention can drive the threaded column and the threaded cover to rotate by rotating the bidirectional threaded rod. When multiple devices are stacked, they can be assembled by the threaded connection between the two.

Its plug and slot block engage, which facilitates the fixing of the left and right devices and makes it easy to assemble multiple devices, thereby improving the reliability of the device.

[0030] 2. The present invention can drive the lifting plate to move up and down by rotating the bidirectional threaded rod, and the linkage connecting frame and rack move synchronously.

[0031] 3. The present invention drives the rotating disk to rotate by starting the motor, which in turn drives the bevel gear to rotate. This drives the meshing bevel gear to rotate, which in turn drives the fan plate to rotate and generate airflow to dissipate heat from the device. At the same time, the rotating disk drives the filter belt through the rotating wheel to intercept impurities in the airflow and discharge them during the transmission, thereby improving the practicality of the device.

[0042] This invention provides a MINILED small-pitch dot matrix display device, including a display 1, a lamp board 5 fixedly connected to the inner side of the display 1, and a mounting plate 6 fixedly connected to the rear side of the display 1.

A threaded post 22 is fixedly connected to the upper side of the bidirectional threaded rod 21, and a threaded cover 23 is fixedly connected to the lower side of the bidirectional threaded rod 21. Rotating the bidirectional threaded rod 21 can drive the threaded post 22 and the threaded cover 23 to rotate. Lifting plates 24 are threadedly connected to the upper and lower sides of the outer side of the bidirectional threaded rod 21. Rotating plates 25 are rotatably connected to the left and right sides of the lifting plates 24. A push plate 26 is rotatably connected to the outer side of the rotating plates 25.

By fixing the slot block 27 and the plug block 28, it is easy to assemble the devices on the left and right sides.

[0044] Specifically, when the bidirectional threaded rod 21 is rotated, the threaded column 22 and the threaded cover 23 will rotate synchronously. When multiple devices are stacked, the upper and lower devices can be assembled through the threaded connection between the threaded column 22 and the threaded cover 23. At the same time, the rotation of the bidirectional threaded rod 21 will drive the lifting plate 24 to move up and down, thereby pushing the rotating plate 25 to rotate, causing the push plate 26 to move left and right along the mounting plate 6. Finally, the left and right devices are fixed by the engagement of the plug block 28 on the push plate 26 and the slot block 27.

[0045] Mounting mechanism 3 includes a bidirectional threaded rod 31, which is rotatably connected to the inner middle of the display 1. Lifting plates 32 are threadedly connected to the upper and lower outer sides of the bidirectional threaded rod 31. Rotating the bidirectional threaded rod 31 can drive the lifting plates 32 to move up and down. Multiple connecting brackets 33 are fixedly connected to the outer side of the lifting plates 32. A rack 34 is fixedly connected to the outer side of the connecting brackets 33. Moving the lifting plates 32 can drive the connecting brackets 33 and the rack 34 to move.

Threaded pillars 36 are fixedly connected to the outer side of the circular gears 35. Mounting blocks 37 are threadedly connected to the outer side of the threaded pillars 36. Rotating the circular gears 35 and the threaded pillars 36 can drive the mounting blocks 37 to move. An operating component 38 is provided on the outer wall of the display 1.

[0046] Specifically, rotating the bidirectional threaded rod 31 can drive the lifting plate 32 to move up and down, which in turn links the connecting frame 33 and the rack 34 to move synchronously. When the rack 34 moves, it will drive the meshing circular gear 35 to rotate, which will drive the threaded column 36 to rotate accordingly. The rotation of the threaded column 36 can push the mounting block 37 to move along the protective plate 211, thereby facilitating the installation and fixing of the device.

[0047] The heat dissipation mechanism 4 includes a motor 41 and a filter belt 48. Multiple motors 41 are fixedly connected to the left and right sides of the outside of the mounting plate 6. The output end of the motor 41 passes through the mounting plate 6 and is fixedly connected to a rotating disk 42. Starting the motor 41 can drive the rotating disk 42 to rotate. A bevel gear 45 is fixedly connected to the outside of the rotating disk 42. The left and right sides of the inside of the display 1 are rotatably connected to a fan plate 46. A bevel gear 44 is fixedly connected to the outside of the fan plate 46. Rotating the bevel gear 44 will drive the fan plate 46 to rotate. The bevel gear 44 meshes with the bevel gear 45. Rotating the bevel gear 45 can drive the bevel gear 44 to rotate. Multiple rotating wheels 47 are rotatably connected to the middle of the inner side of the mounting plate 6. The rotating wheels 47 are connected to the rotating disk 42 through the filter belt 48. The rotating wheels 47 can drive the filter belt 48 through the rotating disk 42. A positioning component 49 is provided on the outside of the mounting plate 6.

[0048] Specifically, the starting motor 41 can drive the rotating disk 42 to rotate, which in turn causes the bevel gear 45 on the disk to rotate synchronously, driving the meshing bevel gear 44 to rotate, which in turn drives the fan plate 46 to rotate. The rotation of the fan plate 46 generates airflow to achieve heat dissipation of the device. At the same time, the rotating disk 42 drives the filter belt 48 through the rotating wheel 47. The filter belt 48 can both intercept impurities in the airflow and discharge the intercepted impurities during the transmission process.

[0049] The assembly mechanism 2 also includes guide rods 29, two guide rods 29 are fixedly connected to the left and right sides of the inside of the mounting plate 6 respectively, and the guide rods 29 are slidably connected to the protective plate 211.

The assembly mechanism 2 also includes brackets 210, multiple brackets 210 are fixedly connected to the left and right sides of the mounting plate 6 respectively, and the outer side of the brackets 210 is fixedly connected to the display 1.

The mounting mechanism 3 also includes a sliding plate 39, which is fixedly connected to the outer periphery of the multiple mounting blocks 37. The sliding plate 39 is slidably connected to the protective plate 211.

[0052] Specifically, rotating the knob 310 can facilitate the synchronous rotation of the bidirectional threaded rod 31, holding the handle 381 makes it easy to hold and carry the device, while the protective sleeve 382 on it can improve the comfort of holding, and the sliding plate 39 can improve the stability of the mounting block 37 when moving along the protective plate 211.

[0053] The heat dissipation mechanism 4 includes a second rotating disk 43, which is rotatably connected to the left and right ends of the mounting plate 6. The first rotating disk 42 is connected to the second rotating disk 43 via a filter belt 48. The second rotating disk 43 can improve the transmission effect of the first rotating disk 42 when transmitting the filter belt 48. The positioning component 49 includes a positioning block 491, which is fixedly connected to the left and right sides of the two mounting plates 6. The inner side of the positioning block 491 is provided with a positioning hole 492. By inserting a threaded part into the positioning hole 492, the device can be easily installed and fixed.

[0054] Specifically, the rotating disk 43 can assist the rotating disk 42 in driving the filter belt 48 in and out during transmission. By inserting a threaded part into the positioning hole 492 on the positioning block 491, the device can be easily installed and fixed.

[0055] Working principle: Rotating the bidirectional threaded rod 21 can drive the threaded column 22 and the threaded cover 23 to rotate. When multiple devices are stacked, the devices on the upper and lower sides can be assembled through the threaded connection between the threaded column 22 and the threaded cover 23. At the same time, as the bidirectional threaded rod 21 rotates, it can drive the lifting plate 24 to move up and down, and as the lifting plate 24 pushes the rotating plate 25 to rotate, the rotating plate 25 can push the push plate 26 to move left and right along the mounting plate 6. At this time, by engaging the insertion block 28 on the push plate 26 with the slot block 27, it is easy to fix the devices on the left and right sides.

[0056] Furthermore, by rotating the bidirectional threaded rod 31, the lifting plate 32 can be moved up and down. At this time, the movement of the lifting plate 32 will drive the connecting frame 33 and the rack 34 on it to move simultaneously. At this time, the movement of the rack 34 will drive the circular gear 35 meshing with it to rotate. At this time, the rotation of the circular gear 35 will drive the threaded column 36 to rotate. As the threaded column 36 rotates, it can push the mounting block 37 to move along the protective plate 211, thereby facilitating the installation and fixation of the device.

[0057] Finally, starting the motor 41 drives the rotating disk 42 to rotate. The rotation of the rotating disk 42 drives the bevel gear 45 on it to rotate. The rotation of the bevel gear 45 drives the bevel gear 44 meshing with it to rotate. The rotation of the bevel gear 44 drives the fan plate 46 to rotate. The rotation of the fan plate 46 drives the airflow to circulate and dissipate heat from the device. At the same time, the rotation of the rotating disk 42 also drives the filter belt 48 to drive through the rotating wheel 47. The filter belt 48 can intercept impurities in the airflow and discharge the intercepted impurities during the transmission process.
