Description

Technical Field

[0001] This utility model relates to the field of LED module technology, and in particular to a modular splicing LED module structure. Background Technology

[0002] In the current LED display field, modular LED module splicing technology has become highly mature, including magnetic connection, snap-fit ​​connection and threaded connection, and is widely used in many scenarios such as indoor and outdoor advertising, stage rental, sports venues, and control centers, providing high-quality display effects and visual experience for various fields.

[0003] In traditional touch LED displays, the infrared sensors are exposed around the screen, which is unsightly. The assembly method is also limited, and the design is only for a certain type of display, which cannot meet the diverse needs of the current market. Traditional splicing mechanisms are usually brackets connected to the back of the LED display modules. Traditional splicing mechanisms require more tools during splicing, which cannot achieve quick installation. Furthermore, in traditional splicing mechanisms, splicing is achieved by connecting the LED display modules to the brackets, and the splicing strength between adjacent LED display modules is not strong, making them prone to positional misalignment.

[0004] The existing patent (publication number: CN209625679U) discloses a modularly installable touch LED display screen. In this utility model, the rotating hooks and crossbars of adjacent cabinets cooperate with each other to not only realize the modular splicing between LED display modules, which is simple and quick to operate, but also improve the splicing strength between LED display modules and avoid positional displacement.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, after prolonged use, most existing modular LED splicing modules require timely cleaning of the dust adhering to the surface of the LED beads to ensure display quality. The cleaning method is mostly manual, using a soft brush. This is particularly time-consuming and labor-intensive when cleaning large-area modular LED splicing modules. Uneven force can easily damage the LED beads, and the operation requires climbing, posing certain safety hazards.

[0006] To address this, a modular LED module structure is proposed. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A modular splicing LED module structure includes a frame 1 and several splicing LED module bodies 2. The top and bottom of the frame 1 are fixedly connected to a fixing plate 3. A suction mechanism 4 is provided between the opposite sides of the two fixing plates 3. A brushing mechanism 5 is provided on the rear side of the suction mechanism 4.

[0030] The brushing mechanism 5 includes three vibration motors 501, a slide plate 502, several brush bristles 503, and several through slots 504. The rear side of the vibration motors 501 is fixedly connected to the front side of the slide plate 502, the front side of the brush bristles 503 is fixedly connected to the rear side of the slide plate 502, and the through slots 504 are opened inside the slide plate 502.

[0031] In this embodiment: After the frame 1 is fixed to the wall, the splicing LED module body 2 is spliced ​​on the front side of the frame 1. When the splicing LED module body 2 needs to be cleaned after use, the suction nozzle 404 is connected to an external vacuum cleaner, and the external controller is connected to a vibration motor 501. The three vibration motors 501 operate synchronously through the external controller, driving the slide plate 502 and brush 503 to vibrate at high frequency. The operator pulls the pull ring 403, and the pull rod 402 rotates through the rotating sleeve 9 and the rotating column 10, so that the suction cover 401 is subjected to force, driving the slide plate 502 and brush 503 to move to the right until the brush 503 contacts the surface of the splicing LED module body 2, shaking off the dust of the LED beads. At the same time, the vacuum cleaner generates negative pressure, which passes through the suction nozzle 404 and the through groove 50 4. Timely dust removal: Compared to manual cleaning, the simultaneous operation of mechanical vibration and negative pressure vacuuming provides a large coverage area and high efficiency. It eliminates the need for staff to climb, thus removing safety hazards. The high-frequency 503 brush bristles, combined with vacuuming, enhance cleanliness, effectively reducing labor costs and the risk of LED chip damage. This solves the problem that after prolonged use, most modular LED modules require timely cleaning of dust adhering to the LED chip surface to maintain display quality. The cleaning method is mostly manual brushing with soft brushes, which is time-consuming and labor-intensive, especially when cleaning large modular LED modules. Uneven force can easily damage the LED chips, and climbing is required, posing certain safety hazards.

[0032] Specifically, such as Figure 3As shown, the suction mechanism 4 includes a suction cover 401, a pull rod 402, a pull ring 403, and a suction nozzle 404. The pull rod 402 is located on the front side of the suction cover 401. The pull ring 403 is fixedly connected to the surface of the pull rod 402. The top of the suction nozzle 404 is fixedly connected to the bottom of the suction cover 401. The suction cover 401 is connected to the through groove 504.

[0033] Specifically, such as Figure 5 As shown, a rotating column 10 is provided on the front side of the suction hood 401, and a rotating sleeve 9 is fixedly connected to the top of the pull rod 402. The rear side of the rotating column 10 passes through the rotating sleeve 9 and is fixedly connected to the front side of the suction hood 401. The surface of the rotating column 10 is in active contact with the inside of the rotating sleeve 9.

[0034] Specifically, such as Figure 5 As shown, a magnetic block 13 is fixedly connected to the front side of the suction cover 401, and the surface of the pull rod 402 is magnetically attracted to the surface of the magnetic block 13.

[0035] In this embodiment: by fixing the external vacuum cleaner to the suction nozzle 404, the operation of the external vacuum cleaner can be controlled. After the brush 503 brushes away the dust from the LED beads on the surface of the spliced ​​LED module body 2, the negative pressure generated by the operation of the external vacuum cleaner can be promptly removed through the through groove 504, suction cover 401 and suction nozzle 404. By rotating the rotating column 10 to the right by holding the pull ring 403, the suction cover 401 can be easily subjected to force in the middle, making it easy to pull the suction cover 401, the slide plate 502 and the brush 503 stably to the right. The magnetic block 13 on the front side of the suction cover 401 is magnetically attracted to the pull rod 402 to limit its movement, thus preventing the pull rod 402 from rotating arbitrarily.

[0036] Specifically, such as Figure 3 and Figure 6 As shown, the fixed plate 3 has a groove 12 inside, and the slide plate 502 is slidably connected inside the groove 12.

[0037] Specifically, such as Figure 4 and Figure 6 As shown, the top and bottom of the rear side of the slide plate 502 are rotatably connected with ball bearings 8. There are several ball bearings 8, which are evenly distributed on the top and bottom of the rear side of the slide plate 502. The surface of the ball bearings 8 is in active contact with the inner wall of the slide groove 12.

[0038] Specifically, such as Figure 3 and Figure 6 As shown, a limiting plate 6 is fixedly connected to the bottom of the rear side of the slide plate 502. A limiting button 7 is provided at the bottom of the limiting plate 6. A limiting hole 11 is opened at the bottom of the bottom fixing plate 3. The top of the limiting button 7 passes through the limiting plate 6 and extends into the interior of the limiting hole 11. The surface of the limiting button 7 is threadedly connected to the interior of the fixing plate 3.

[0039] Specifically, such as Figure 4As shown, the bristles 503 are synthetic fibers with a diameter of 10-20 μm.

[0040] In this embodiment: the slide plate 502 is slidably connected to the inside of the slide groove 12. The ball bearing 8 reduces the friction between the slide plate 502 and the slide groove 12, making the slide plate 502 slide more easily and smoothly. When the slide plate 502 moves to the leftmost side of the slide groove 12, the limit button 7 is rotated. The limit button 7 is connected to the inside of the limit plate 6 by a thread. When the limit button 7 is rotated, the limit button 7 can be moved. Moving the limit button 7 upward into the limit hole 11 can limit the slide plate 502 to the leftmost side of the slide groove 12, avoiding obstruction of the splicing LED module body 2. The 10-20μm diameter synthetic fiber bristles 503 are soft in texture and avoid scratching the LED beads on the surface of the splicing LED module body 2.

[0041] Working principle: After the frame 1 is fixed to the mounting wall, the splicing LED module body 2 is spliced ​​to the frame 1. The splicing of the splicing LED module body 2 and the splicing between the splicing LED module bodies 2 is a well-established and publicly available technology, which will not be elaborated here. When the surface of the LED beads needs cleaning due to dust accumulation after prolonged use, the suction nozzle 404 is first connected to an external vacuum cleaner through a hose, and the external controller is connected to the vibration motor 501. The operator turns on the vibration motor 501 through the external controller. The three vibration motors 501 operate synchronously, generating high-frequency vibrations that are transmitted to the slide plate 502, which drives the bristles fixed to the back of the slide plate 502. 503 high-frequency vibration. Subsequently, the operator pulls the pull ring 403 to rotate the pull rod 402 to the right. The pull rod 402 is connected to the rotating column 10 through the rotating sleeve 9, causing the middle of the suction hood 401 to be stressed. Since the sliding plate 502 is slidably connected in the sliding groove 12 of the fixed plate 3, and the ball bearing 8 on the rear side of the sliding plate 502 can reduce the sliding friction, the suction hood 401 drives the sliding plate 502 and the brush 503 to move to the right as a whole until the brush 503 is in close contact with the surface of the spliced ​​LED module body 2. At this time, the high-frequency vibration of the brush 503 can effectively shake off the dust on the surface of the LED beads and in the gaps. At the same time, the external vacuum cleaner starts to generate negative pressure, and the airflow enters the suction nozzle 404. The dust, shaken off by the cover 401 and the through groove 504 inside the slide plate 502, is promptly sucked away to prevent secondary adhesion or scattering of dust. After cleaning, the suction cover 401 and the slide plate 502 are moved to the leftmost side of the slide 12. Then, the limit button 7 is rotated so that its top passes through the limit plate 6 and screws into the limit hole 11, fixing the slide plate 502 to the leftmost side of the slide 12 to avoid obstructing the spliced ​​LED module body 2. After cleaning, the pull rod 402 is rotated in the opposite direction so that the magnetic block 13 on the front side of the suction cover 401 is magnetically attracted and limited by the pull rod 402. Compared with the existing manual cleaning, the efficiency is greatly improved. Manual cleaning requires brushing dust off piece by piece, while this structure can use mechanical vibration and negative pressure to vacuum. Simultaneous operation covers a larger area, shortens the cleaning time per session, eliminates the need for manual climbing, and removes the risk of falls. The high-frequency vibrating 503 brush bristles can reach deep into the gaps between LED beads, combined with negative pressure vacuuming, achieving a level of cleanliness superior to manual cleaning, reducing labor costs. This solves the problem that after prolonged use, most modular splicing LED modules require timely cleaning of dust adhering to the surface of the LED beads to maintain display quality. The cleaning method is mostly manual brushing with soft brushes, which is time-consuming and labor-intensive, especially when cleaning large-area modular splicing LED modules. It is also prone to damaging the LED beads due to uneven force and requires climbing, posing certain safety hazards.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
