Description

Technical Field

[0001] This utility model relates to the field of COB display technology, and in particular to a COB display module. Background Technology

[0002] COB displays directly encapsulate LED light-emitting chips onto a PCB (printed circuit board) substrate, covering and protecting them with a special polymer material to form a dense pixel array to display images. This encapsulation method eliminates the need for traditional brackets and lens structures, making the encapsulation process more streamlined, while improving the luminous efficiency and stability of the display.

[0003] COB displays used outdoors or in shopping malls are generally mounted on walls at a considerable height. The displays are also quite large and are usually assembled from multiple smaller display modules. If one of them is damaged, workers need to use hoisting tools to lift it into the air to remove it, which is inconvenient and poses a significant safety hazard, making it unsuitable for practical use. Utility Model Content

[0004] The purpose of this utility model is to provide a COB display module that solves the problem that COB displays used outdoors or in shopping malls are generally installed on walls at a relatively high height, and the display screens are large in size. They are usually assembled from multiple small display modules. If one of them is damaged, workers need to use hoisting tools to go up to the air to operate it, which makes operation inconvenient and poses a significant safety hazard, making it inconvenient for actual use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A COB display module includes a mounting housing and a display mounting bracket for mounting the display screen.

A driving component is disposed inside the mounting housing for suspending the mounting plate. The driving component includes two winding wheels, both of which are rotatably connected inside the mounting housing and have steel wire ropes wound around their surfaces. The ends of the steel wire ropes away from the winding wheels are connected to the mounting plate. A limiting component is disposed at the bottom of both ends of the mounting housing for limiting the mounting plate.

[0007] Preferably, the mounting shell has a sliding groove on the side where the two arms are close to each other, and the mounting plate is located inside the sliding groove.

[0008] Preferably, the driving component further includes a motor, which is fixedly mounted on the side wall of the mounting housing. A transmission shaft is rotatably connected inside the mounting housing. The output shaft port of the motor is fixedly connected to the transmission shaft. Two worm gears are fixedly mounted on the surface of the transmission shaft. A second rotating shaft is fixedly passed through the surface of each of the two winding wheels. The winding wheels are rotatably connected to the mounting housing through the second rotating shaft. A worm wheel is fixedly mounted on the surface of the second rotating shaft. The two worm gears mesh with the two worm wheels respectively.

[0009] Preferably, the interior of the mounting housing is provided with two pulleys at positions relative to the two winding wheels. A first rotating shaft is fixedly passed through the surface of each of the two pulleys. The pulleys are rotatably connected to the mounting housing through the first rotating shafts. The two steel wire ropes pass through the two pulleys respectively and are then connected to the mounting plate.

[0010] Preferably, the limiting component includes two electrically operated telescopic rods and two sliding rods. The sliding rods have an "L"-shaped structure. The two sliding rods slide through the two arms of the mounting housing near the bottom. The two electrically operated telescopic rods are fixedly installed on the two arms of the mounting housing, and the output ends of the two electrically operated telescopic rods are fixedly connected to the two sliding rods respectively.

[0011] Preferably, a connecting rod is fixedly installed on the surface of the mounting plate. The connecting rod has a "C"-shaped structure.

[0028] Reference Figure 1-6 A COB display module includes a mounting shell 1 and a display mounting bracket 5 for mounting the display screens. Multiple display screens are assembled on the display mounting bracket 5. Each display screen is connected in series with connecting wires to form an integrated display module. The mounting shell 1 is configured as an "n" shaped structure. The mounting plate 3 is provided inside the mounting shell 1, and the width of the mounting plate 3 is adapted to the size between the two arms of the mounting shell 1. The display mounting bracket 5 is disposed on the surface of the mounting plate 3.

[0029] Drive component 4 is located inside the mounting housing 1 for hoisting mounting plate 3. Drive component 4 includes two winding wheels 45, both of which are rotatably connected inside the mounting housing 1 and have steel wire ropes 49 wound on their surfaces. The end of the steel wire rope 49 away from the winding wheels 45 is connected to the mounting plate 3.

[0030] Limiting element 2 is provided at the bottom of both ends of the mounting shell 1 to limit the mounting plate 3.

[0031] Furthermore, each of the two arms of the mounting shell 1 has a groove 12 on the side where they are close to each other, and the mounting plate 3 is located inside the groove 12.

[0032] Furthermore, the drive component 4 also includes a motor 42, which is fixedly mounted on the side wall of the mounting housing 1. A transmission shaft 41 is rotatably connected inside the mounting housing 1. The output shaft port of the motor 42 is fixedly connected to the transmission shaft 41. Two worm gears 47 are fixedly mounted on the surface of the transmission shaft 41. A second rotating shaft 44 is fixedly passed through the surface of each of the two winding wheels 45. The winding wheels 45 are rotatably connected to the mounting housing 1 through the second rotating shaft 44. A worm wheel 48 is fixedly mounted on the surface of the second rotating shaft 44. The two worm gears 47 mesh with the two worm wheels 48 respectively. When the motor 42 is started, the motor 42 drives the transmission shaft 41 to rotate. The transmission shaft 41 drives the two worm gears 47 to rotate. The two worm gears 47 drive the two worm wheels 48 to rotate. The two worm wheels 48 drive the two second rotating shafts 44 to rotate. The two second rotating shafts 44 drive the two winding wheels 45 to rotate. The spiral directions of the two worm gears 47 are opposite, so that the rotation directions of the two worm wheels 48 and the winding wheels 45 are opposite. Thus, the winding wheels 45 are used to realize the winding or unwinding of the wire rope 49.

[0033] Furthermore, two pulleys 46 are provided inside the mounting shell 1 at positions relative to the two winding wheels 45. A first rotating shaft 43 is fixedly passed through the surface of each pulley 46. The pulleys 46 are rotatably connected to the mounting shell 1 through the first rotating shaft 43. Two steel wire ropes 49 pass through the two pulleys 46 respectively and are connected to the mounting plate 3. The pulleys 46 make the hoisting of the mounting plate 3 by the steel wire ropes 49 more stable, avoiding instability in the hoisting of the mounting plate 3 caused by changes in the amount of steel wire ropes 49 wound around the winding wheels 45.

[0034] Furthermore, the limiting component 2 includes two electric telescopic rods 22 and two sliding rods 21. The sliding rods 21 have an "L" shape structure. The two sliding rods 21 slide through the two arms of the mounting shell 1 near the bottom. The two electric telescopic rods 22 are fixedly installed on the two arms of the mounting shell 1. The output ports of the two electric telescopic rods 22 are fixedly connected to the two sliding rods 21. When the entire mounting plate 3 is pulled into the interior of the mounting shell 1, the electric telescopic rods 22 can be used to drive the sliding rods 21 to move to the bottom of the mounting plate 3. Thus, the sliding rods 21 support the entire mounting plate 3, preventing the wire rope 49 from being worn due to long-term gravity. The motor 42, electric telescopic rods 22, and other electrical equipment are all controlled by a controller, which is controlled by a remote control. The signal control principle is existing technology and will not be elaborated further here.

[0035] Furthermore, a connecting rod 31 is fixedly installed on the surface of the mounting plate 3. The connecting rod 31 has a "C"-shaped structure. One end of the display mounting bracket 5 is rotatably connected to the connecting rod 31. Two fixing blocks 32 are fixedly installed on the surface of the mounting plate 3. Insert rods 33 slide through the surface of both fixing blocks 32. The end of the display mounting bracket 5 away from the connecting rod 31 has a slot that matches the size of the insert rod 33. When the entire mounting plate 3 is pulled down by the steel wire rope 49, the insert rod 33 can be pulled out directly. Then the entire display mounting bracket 5 can be rotated to expose the position behind the display screen for operation, which is convenient for use. During installation, the insert rod 33 can be directly inserted into the slot to fix the display mounting bracket 5 on the mounting plate 3.

[0036] Furthermore, the bottom end of the slide 12 is set as a smooth slope, which helps the mounting plate 3 to directly enter the interior of the slide 12 during the hoisting process. Both sides of the mounting shell 1 are integrally formed with connecting ears 11, and bolts are provided on the surface of the connecting ears 11. The entire mounting shell 1 is fixed to the wall by bolts.

[0037] In summary, by centrally mounting the displays on the display mounting bracket 5, which is rotatably connected to the mounting plate 3, the entire display mounting bracket 5 can be rotated out and operated from the rear during display maintenance, eliminating the need to disassemble multiple displays. Furthermore, the entire mounting plate 3 is suspended in the mounting shell 1 by steel wire rope 49, so if a display at a high position is damaged, it can be pulled down directly for operation. After maintenance, it can be hoisted back up, reducing safety hazards and simplifying the installation process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
