Description

Technical Field

[0001] This utility model relates to the field of display screen protection technology, specifically an LED display screen with a protective structure. Background Technology

[0002] LED displays are flat panel displays that use light-emitting diodes (LEDs) as pixels to generate images and videos. They are widely used in various indoor and outdoor locations to display advertisements, information, entertainment content, etc. LED displays with protective structures refer to LED displays that have adopted special protective measures in the design and manufacturing process to adapt to various environments.

[0003] The patent document with authorization announcement number CN221927452U describes an LED display screen with a protective structure. The described solution uses tempered glass to protect the front end of the LED display screen from direct impact from external forces, which could cause damage. A fixed frame is fixedly connected to the opening on the front face of the protective shell. The outer edge of the fixed frame is inserted into a rectangular embedded groove at the opening on the front face of the protective shell for limiting connection, so that the front end of the fixed frame is flush with the front face of the protective shell, improving aesthetics. By setting a spring, the tempered glass can retract into the protective shell when it is impacted by external forces, and the spring provides cushioning to prevent excessive external forces from directly acting on the tempered glass and causing damage.

[0004] The aforementioned technologies have the problem of not being able to cool down the LED modules. Different colored LED beads have different sensitivities to temperature. High temperatures can cause inconsistent light decay rates among different colored LED beads, resulting in color drift and affecting the color reproduction and image quality of the display screen. Furthermore, the aforementioned technologies also have the problem of not being able to raise or lower the LED modules. LED displays are usually installed in high places. If they cannot be raised or lowered, heavy equipment such as cranes and hoists are required to lift the modules to the designated positions, which increases the difficulty and risk of installation. During the use of LED displays, some modules may malfunction. If they cannot be raised or lowered, maintenance personnel need to climb to high places to inspect or replace the modules, which increases the difficulty of maintenance and safety risks.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] In one embodiment, such as Figures 1-4 As shown, an LED display screen with a protective structure includes: a support frame 100, a slider 200, a protective housing 300, an LED module 400, and a cooling component. The slider 200 is slidably connected inside the support frame 100. The protective housing 300 is disposed on one side of the slider 200. The LED module 400 is disposed inside the protective housing 300. The cooling component includes a ventilation duct 501 disposed inside the protective housing 300. A filter plate 502 is provided at one end of the protective housing 300. A support frame 503 is provided at one end inside the protective housing 300.

Several air guide plates 506 are provided on the side of the ventilation duct 501 near the LED module 400. The protective box 300 is provided with a limiting component to limit the filter plate 502. The top of the protective box 300 is provided with a protective component to protect the LED module 400. The support frame 100 is provided with a lifting component to raise and lower the slider 200. The air is filtered by the filter plate 502. Then the first motor 504 is started to drive the rotating blades 505 to rotate, so that the filtered air can reach the interior of the ventilation duct 501. Then the air is guided to the LED module 400 by the air guide plates 506.

[0032] In one embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the limiting assembly includes two rotating columns 601, which are rotatably connected to the interiors of both ends of the protective housing 300. Each of the two rotating columns 601 has a rotating gear 602 at one end, and each of the two rotating gears 602 meshes with two racks 603. The ends of the two racks 603 are slidably connected to the interior of the filter plate 502. Each of the two rotating columns 601 has a handle 604 at the end away from the rotating gear 602. Each of the two handles 604 has a limiting rod 605 inside the end away from the rotating column 601. Each limiting rod 605 has a limiting block 606 at the end near the protective housing 300. The protective housing... The body 300 has several limiting holes 607 on one side of the limiting block 606, which are adapted to the limiting block 606. The limiting block 606 is slidably connected inside the limiting holes 607. A spring 608 is provided between the two handles 604 and the limiting block 606. One end of the spring 608 passes through the inside of the limiting block 606, and the other end of the spring 608 passes through the inside of the handle 604. By pulling the limiting rod 605, the limiting block 606 is moved away from the limiting hole 607. Then, the handle 604 is rotated, which drives the rotating gear 602 to rotate, thereby driving the rack 603 to move away from the inside of the filter plate 502, so that the filter plate 502 can be disassembled.

[0033] In one embodiment, such as Figure 1 and Figure 3 As shown, the protective assembly includes two support blocks 701, which are respectively located at both ends of the top of the protective housing 300. A rotating rod 702 is rotatably connected between the two support blocks 701. A protective plate 703 is fixedly connected to the outer surface of the rotating rod 702. A second motor 704 is installed on one end of the protective housing 300. A worm gear 705 is provided at the output end of the second motor 704. The worm gears 705 are meshed with worm wheels 706, and the worm wheel shaft of the worm wheel 706 is connected to the rotating rod 702. By starting the second motor 704, it drives the worm gear 705 to rotate, thereby driving the worm wheel 706 and the rotating rod 702 to rotate, thereby driving the protective plate 703 to move closer to the protective housing 300 and protect the LED module 400.

[0034] In one embodiment, such as Figure 1As shown, the lifting assembly includes a third motor 801, which is located at the top of the support frame 100. The output end of the third motor 801 is provided with a threaded rod 802, which is rotatably connected to the inside of the support frame 100 and threadedly connected to the inside of the slider 200. Both ends of the inside of the support frame 100 are provided with limiting rods, and both limiting rods are slidably connected to the inside of the slider 200. By starting the third motor 801, it drives the threaded rod 802 to rotate, and then, under the action of the limiting rods, it drives the slider 200 to rise and fall inside the support frame 100.

[0035] In one embodiment, such as Figure 1 As shown, the support frame 100 is provided with mounting plates on all four sides to facilitate the installation of the support frame 100.

[0036] In one embodiment, such as Figure 1 As shown, the protective plate 703 is made of acrylic material. Acrylic has a very high light transmittance, which can ensure the brightness of the LED module, provide a good light diffusion effect, make the light more uniform, reduce glare, and improve visual comfort. In addition, acrylic has high impact resistance and is not easy to break. Even if it breaks, it will not produce sharp fragments, reducing safety risks and providing good protection for the LED module.

[0037] In one embodiment, such as Figure 4 As shown, each of the two limiting rods 605 has a pull ring on the end away from the limiting block 606, which facilitates pulling the limiting rod 605.

[0038] In one embodiment, such as Figure 1 As shown, a control panel is provided at one end of the lower part of the support frame 100, and the control panel is electrically connected to the first motor 504, the second motor 704 and the third motor 801. The control panel facilitates the control of the first motor 504, the second motor 704 and the third motor 801.

[0039] The above embodiment discloses an LED display screen with a protective structure. A support frame 100 is installed using a mounting plate. Then, a third motor 801 is started, causing a threaded rod 802 to rotate. Under the action of a limiting rod, the threaded rod drives a slider 200 to rise and fall within the support frame 100, thereby raising and lowering the LED module 400 to a suitable position. Next, a second motor 704 is started, causing a worm gear 705 to rotate, which in turn drives a worm wheel 706 and a rotating rod 702 to rotate. This causes a protective plate 703 to approach the protective housing 300, protecting the LED module 400. Air is then filtered by a filter plate 502. Finally, a first motor 504 is started, causing a rotating blade 505 to rotate, allowing the filtered air to reach the ventilation duct 501 and then pass through an air guide plate 50. 6. The air is directed to the LED module 400 to cool it down. When the filter plate 502 needs to be replaced, the third motor 801 can be restarted to move the protective box 300 to a suitable height. Then, the limit rod 605 is pulled, causing the limit block 606 to squeeze the spring 608 and move away from the limit hole 607. Then, the handle 604 is turned, causing the rotating gear 602 to rotate, thereby moving the rack 603 away from the inside of the filter plate 502, so that the filter plate 502 can be removed and a new filter plate 502 can be placed. Then, the handle 604 is turned again, causing the rack 603 to move into the filter plate 502. Then, the pulling force on the limit rod 605 is released, and under the elastic force of the spring 608, it moves the limit block 606 into the limit hole 607, thereby limiting the handle 604.

[0040] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
