Technical Field

[0001] This application relates to foldable LED displays. Background Technology

[0002] LED electronic displays are a type of display that uses controlled semiconductor light-emitting diodes (LEDs). They consist of tens of thousands to hundreds of thousands of LED pixels arranged uniformly. By utilizing different materials, LED pixels of different colors can be manufactured to display various information such as text, graphics, images, animations, market data, video, and recorded signals. LED electronic displays integrate microelectronics technology, computer technology, and information processing, and have advantages such as vibrant colors, wide dynamic range, high brightness, long lifespan, and stable and reliable operation. LED displays are widely used in commercial media, cultural performances, sports venues, information dissemination, news releases, and securities trading, meeting the needs of diverse environments.

[0003] When conducting outdoor activities, LED displays are needed to show the content of the event. The displays need to be carried. Since the displays are heavy and fragile, they are usually carried in protective cases. However, when using LED displays outdoors, additional support brackets are needed to support the displays, which is inconvenient to carry and cumbersome to fix. Moreover, the displays are prone to accumulating dust and pollutants. It is not convenient to clean the displays outdoors. Directly storing the displays will cause dust and pollutants to accumulate on the screen, making parts of the display blurry and unusable.

[0004] Therefore, we are looking to provide foldable LED displays. Utility Model Content

[0005] This embodiment provides a foldable LED display screen, which solves the problems of needing to carry a separate fixing frame to support the LED display screen, which is inconvenient to carry, cumbersome to fix, and difficult to clean dust and contaminants on the display screen.

[0006] According to one aspect of this application, a foldable LED display screen is provided, including a display screen body, the bottom end of which is fixed to the inner end of a mounting box via a rotating structure, and a folding structure is fixed inside the mounting box at the bottom of the rotating structure. The foldable LED display screen further includes:

[0007] A storage and support structure is provided at the bottom of the mounting box;

[0008] The cleaning cotton is fixed at both ends of the top of the storage and support structure.

[0009] Furthermore, the rotating structure includes a fixed block and a rotating shaft. The fixed block is symmetrically fixed at both ends of the bottom of the display screen body, and the fixed block is slidably connected to both ends of the rotating shaft. The two ends of the rotating shaft are fixed to the inner walls of both sides of the mounting box.

[0010] Furthermore, the folding structure includes a motor, a winding shaft, a wire rope, a through hole, a guide rod, and a fixing plate, with the motor fixed to the side wall of the mounting box at one bottom end of the shaft.

[0011] Furthermore, guide rods are provided on the upper and lower rear sides of the mounting box, and fixing plates are fixed at both ends of the guide rods. The fixing plates are fixed to the side wall of the mounting box, and rollers are rotatably connected to both ends of the guide rods.

[0012] Furthermore, a winding shaft is fixed to the motor output end through the side wall of the mounting box, and the other end of the winding shaft is rotatably connected to the inner wall of the other side of the mounting box. Steel wire ropes are fixed to both ends of the winding shaft.

[0013] Furthermore, the rear side wall of the mounting box corresponding to the steel wire rope is provided with a through hole, and one end of the steel wire rope passes through the corresponding through hole and guide rod and is fixed to the top of the rear side wall of the display screen body.

[0014] Furthermore, the storage and support structure includes a support plate, a storage box, an opening, and an L-shaped baffle. The storage box is fixed to the bottom of the support plate, and cleaning cotton is fixed to both ends of the top of the support plate.

[0015] Furthermore, the bearing plate is fixed with sliding rods at both ends, and the sliding rods are slidably connected in the sliding groove, which is laterally arranged on the inner walls of both sides of the mounting box.

[0016] Furthermore, the mounting box corresponding to the support plate and the storage box has an opening on the side wall away from the pivot, and an L-shaped baffle is fixed to one end of the support plate and the storage box through the opening.

[0017] Furthermore, a threaded knob is threadedly connected to the top center of the L-shaped baffle, and a threaded groove is provided on the top side wall of the mounting box corresponding to the threaded knob away from the rotating shaft.

[0018] The advantages of this application are:

[0019] 1. By rotating the display screen body to the mounting box via a rotating structure, and by providing a folding structure for both the display screen body and the mounting box, when using the display screen body, the motor in the folding structure drives the winding shaft to rotate, thereby winding up the steel wire rope and pulling up one end of the display screen body. This causes the display screen to rotate along the shaft, standing the display screen body upright. One side wall of the mounting box is higher than the other side walls, which can limit the position of the display screen body and prevent it from tilting. No additional fixing frame is needed to support the main display screen, making it convenient to use.

[0020] 2. By setting up a support and storage structure inside the mounting box, when using an outdoor LED display screen and needing to display some products, after supporting the main body of the display screen, pull the baffle to pull out the support plate and storage box, take out the products stored in the storage box, and then push the support plate and storage box back into the mounting box to place the products on the support plate for display, thus improving practicality.

[0021] 3. Fix cleaning cotton at both ends of the top of the support plate. After the display screen is used, the motor in the folding structure drives the winding shaft to rotate, unwinding the wire rope and folding the display screen body into the mounting box. At this time, the display screen on the display screen body contacts the cleaning cotton on the top of the support plate. Pull the baffle to pull out the support plate. During the pulling process, the cleaning cotton can wipe the dust and contaminants on the display screen clean. Then, pat the cleaning cotton at the top outer end of the support plate clean. Cleaning is convenient. Then push the operation plate into the mounting box to avoid dust and contaminants sticking to the display screen and causing pollution, making the display screen blurry and unusable.

[0034] Please see Figure 1-4 As shown, the foldable LED display screen includes a display screen body 1. The bottom end of the display screen body 1 is fixed to the inner end of the mounting box 3 via a rotating structure 2. A folding structure 4 is fixed inside the mounting box 3 at the bottom of the rotating structure 2. The foldable LED display screen also includes:

[0035] The storage and support structure 5 is disposed at the bottom of the mounting box 3.

[0036] The cleaning cotton 6 is fixed at both ends of the top of the storage and support structure 5.

[0037] The rotating structure 2 includes a fixing block 201 and a rotating shaft 202. The fixing block 201 is symmetrically fixed at both ends of the bottom of the display screen body 1. The fixing block 201 is slidably connected to both ends of the rotating shaft 202. Both ends of the rotating shaft 202 are fixed to the inner walls of both sides of the mounting box 3.

[0038] The folding structure 4 includes a motor 401, a winding shaft 402, a wire rope 403, a through hole 404, a guide rod 405, and a fixing plate 406. The motor 401 is fixed to the side wall of the mounting box 3 at one bottom end of the rotating shaft 202.

[0039] The mounting box 3 has guide rods 405 on the upper and lower rear sides. The guide rods 405 are fixed with fixing plates 406 at both ends. The fixing plates 406 are fixed to the side wall of the mounting box 3. The guide rods 405 are rotatably connected with rollers 11 at both ends.

[0040] The output end of the motor 401 is fixed with a winding shaft 402 through the side wall of the mounting box 3. The other end of the winding shaft 402 is rotatably connected to the inner wall of the other side of the mounting box 3. Steel wire ropes 403 are fixed at both ends of the winding shaft 402. The motor 401 can drive the winding shaft 402 to rotate forward or in reverse.

[0041] The mounting box 3 corresponding to the steel wire rope 403 has a through hole 404 on its rear side wall. One end of the steel wire rope 403 passes through the corresponding through hole 404 and guide rod 405 and is fixed to the top of the rear side wall of the display screen body 1.

[0042] In this technical solution, when the display screen body 1 is in use, the motor 401 in the folding structure 4 drives the winding shaft 402 to rotate, winding the steel wire rope 403 to pull up one end of the display screen body 1, causing the display screen to rotate along the rotating shaft 202, thus erecting the display screen body 1. One side wall of the mounting box 3 is higher than the other side walls, which can limit the position of the display screen body 1, preventing the display screen body 1 from tilting. No additional fixing frame is needed to support the main display screen, making it convenient to use. After the display screen is used, the motor 401 in the folding structure 4 drives the winding shaft 402 to rotate, unwinding the steel wire rope 403 and folding the display screen body 1, so that the display screen body 1 is stored in the mounting box 3. The mounting box 3 is moved by the rollers 11, making it easy to transport and carry the display screen.

[0043] The storage and support structure 5 includes a support plate 501, a storage box 502, an opening 503 and an L-shaped baffle 504. The storage box 502 is fixed to the bottom of the support plate 501, and cleaning cotton 6 is fixed to both ends of the top of the support plate 501.

[0045] In this technical solution, when the display screen body 1 is stored in the mounting box 3, the display screen on the display screen body 1 contacts the cleaning cotton 6 on the top of the support plate 501. Pulling the baffle pulls out the support plate 501. During the pulling process, the cleaning cotton 6 can wipe the dust and contaminants on the display screen clean. Then, the cleaning cotton 6 on the top outer end of the support plate 501 is patted clean, making cleaning convenient. Then, the operation board is pushed into the mounting box 3 to avoid dust and contaminants from sticking to the display screen and causing pollution to the display screen, making the display screen part blurry and unsuitable for use.

[0046] The mounting box 3 corresponding to the support plate 501 and the storage box 502 has an opening 503 on its side wall away from the rotating shaft 202. One end of the support plate 501 and the storage box 502 passes through the opening 503 and is fixed with an L-shaped baffle 504.

[0047] In this technical solution, when using an outdoor LED display screen to showcase some products, after supporting the main body 1 of the display screen, pull the baffle to pull out the support plate 501 and the storage box 502, take out the products stored in the storage box 502, and push the support plate 501 and the storage box 502 back into the mounting box 3, and place the products on the support plate 501 for display, thereby improving practicality.

[0048] The L-shaped baffle 504 has a threaded knob 9 connected to the top center. The mounting box 3 corresponding to the threaded knob 9 has a threaded groove 10 on the top of the side wall away from the rotating shaft 202. The baffle can be fixed to the mounting box 3 by the threaded knob 9 and the threaded groove 10, thereby fixing the operation panel and the storage box 502 to the mounting box 3. When storing the display screen body 1, the top of the L-shaped baffle 504 can limit the position of the display screen.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
