Therefore, they should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] like Figures 1 to 7 As shown, according to a first aspect of this application, this application provides a sealing structure 30 used in the frame structure 10 of a display screen. The frame structure 10 is provided with a through-slot structure 11 for accommodating electronic devices. The sealing structure 30 is disposed at one or both ends of the through-slot structure 11, so that part of the through-slot structure 11 can become a sealed cavity, preventing external moisture from entering the sealed cavity and causing short circuits or functional failures of the electronic devices inside the sealed cavity, effectively enhancing the waterproof performance of the display screen. The electronic devices can be a central control component 20 or electronic components constituting the central control component 20, etc. The frame structure 10 can be a central control box or a strip frame for mounting the light strip module 50, etc., and this application does not impose any limitations.

[0035] In one optional embodiment, the frame structure 10 is a polygonal structure integrally manufactured from aluminum profiles. The aluminum profiles have good thermal conductivity, which enhances heat dissipation of the light strip module 50 and / or the central control component 20, effectively reducing the temperature of the light strip module 50 and / or the central control component 20, extending the service life of the devices, and making them lightweight. Furthermore, the aluminum profiles also feature thinness and resistance to electromagnetic radiation.

[0036] In an optional embodiment, the sealing structure 30 includes a first support member 31, a second support member, a soft rubber part 33, and a first connector 34. The soft rubber part 33 is disposed between the first support member 31 and the second support member. The first connector 34 passes through the first support member 31, the soft rubber part 33, and the second support member in sequence, and is used to lock the soft rubber part 33 between the first support member 31 and the second support member. By adjusting the locking stroke of the first connector 34, the soft rubber part 33 can be made to bulge outward under the pressure of the first support member 31 and the second support member to form a colloid 3311. The colloid 3311 is used to abut against the inner wall of the frame structure 10 to form a circumferential seal, preventing external moisture from entering the sealed cavity, making the performance of the display screen more stable, extending its service life, and improving the service life of the display screen.

[0037] In an optional embodiment, the first connector 34 is used to apply pressure to the soft rubber part 33, so that the soft rubber part 33 can be deformed under the extrusion of the first metal sheet and the second metal sheet to form a protruding rubber body 3311. The rubber body 3311 abuts against the inner wall of the through groove structure 11, which can form a certain friction, so that the entire structure of the sealing structure 30 can form a certain stability with the through groove structure 11, enhance the sealing performance between the sealing structure 30 and the through groove structure 11, and provide support for the subsequent glue pouring step.

[0038] In an optional embodiment, the second support member is provided with an adjusting screw and a locking screw hole. The locking screw hole and the adjusting screw cooperate with each other to adjust the locking stroke of the first connecting member 34 and to deform the soft rubber part 33 under the pressure of the first support member 31 and the second support member to form a colloid 3311. The colloid 3311 abuts against the inner sidewall of the through groove structure 11 to form a circumferential seal. At the same time, it can also prevent the sealing structure 30 from moving relative to the frame structure 10 in the through groove structure 11, which facilitates the disassembly and assembly of the sealing structure 30.

[0039] In one optional embodiment, the number of first connecting members 34 is multiple, which can be, but is not limited to, screw structures. The second support member has a locking screw hole that mates with the screw structure. The screw structure passes through the first support member 31 and the soft rubber pad and is threaded into the locking screw hole. The locking stroke of the first connecting member 34 is controlled by the engagement of the locking screw hole and the screw structure, bringing the distance between the first support member 31 and the second support member closer. This compresses and deforms the soft rubber part 33 sandwiched in the middle, causing the deformed protruding rubber body 3311 to contact the inner wall of the through-slot structure 11, thus completing the initial sealing of both ends of the through-slot structure 11. When the rubber strip contacts the inner wall of the through-slot structure 11, it can create a certain amount of friction, allowing the entire structure of the sealing structure 30 to achieve a certain stability with the inner wall of the through-slot structure 11, providing support for the subsequent glue-filling step.

[0040] In an optional embodiment, a soft rubber through hole is formed on the soft rubber part 33. The soft rubber through hole is used for the cable 60 that is electrically connected to the electronic device to pass through. Under the compression of the first support member 31 and the second support member, it forms a circumferential seal with the cable 60, which prevents external moisture from entering the sealed cavity from the gap between the inner wall of the soft rubber through hole and the cable 60. This prevents the electronic device in the sealed cavity from short-circuiting, makes the performance of the display screen more stable, extends its service life, and improves the service life of the display screen.

[0041] In an optional embodiment, the soft rubber component 33 includes a silicone pad 331 and a silicone sleeve 332. A soft rubber through hole is formed in the silicone pad 331 and the silicone sleeve 332. The shape of the silicone pad 331 is adapted to the shape of the through groove structure 11. The silicone sleeve 332 at least partially passes through the second support member and wraps around the outside of the cable 60, so that the silicone sleeve 332 can be interference-fitted with the cable 60 to seal the cable 60 and the through groove structure 11, especially to achieve sealing by deformation under the compression of the first support member 31 and the second support member.

[0042] In an optional embodiment, the sealing structure 30 further includes a limiting member 35, which is at least partially disposed on the outside of the silicone sleeve 332 to restrict the movement of the sealing structure 30 within the through groove structure 11, so that the sealing structure 30 can be firmly fixed in the through groove structure 11 and provide support for the subsequent potting step.

[0043] In an optional embodiment, the limiting member 35 includes a first limiting ring 351 and a second limiting ring 352. The first limiting ring 351 is sleeved on the outside of the silicone tube sleeve 332, and the second limiting ring 352 is sleeved on the outside of the cable 60 and located on the side of the silicone tube sleeve 332 facing away from the first support member 31, to prevent the entire sealing structure 30 from moving and to provide support for the subsequent potting step.

[0044] In an optional embodiment, the sealing structure 30 further includes an encapsulant 3311. An encapsulant groove 36 is formed between the inner sidewall of the through-slot structure 11 and the first support member 31 and the soft rubber member 33. The encapsulant 3311 is filled in the encapsulant groove 36, which can effectively prevent external dust, foreign objects or liquids from entering the interior of the through-slot structure 11 and causing corrosion to the electronic components inside the through-slot structure 11. This allows the display screen to be used outdoors in humid or liquid environments, such as in rainy environments.

[0045] It should be noted that the potting compound 3311 can form an annular groove around the outer side of the first support member 31 by the inner side wall of the through groove structure 11, the outer side wall of the first support member 31, and the outer end face of the soft rubber part 33. The potting compound 3311 can also be the entire recessed groove structure formed by the inner side wall of the through groove structure 11 and the sealing structure 30. That is, the potting compound 3311 can cover the outer side of the first support member 31 and the first connector 34 to seal the gap between the first connector 34 and the first support member 31. This application does not limit this.

[0046] In an optional embodiment, the first support 31 and the second support are metal sheets made of metal material, the shape of which is adapted to the shape of the through groove structure 11, and the metal sheets have good hardness and thermal conductivity.

[0047] like Figures 1 to 7 As shown, according to a second aspect of this application, this application provides a central control component 20, which is used in a display screen, including a frame structure 10 and the aforementioned sealing structure 30.

Parts not mentioned in this embodiment can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0051] In an optional embodiment, the LED light strip includes a light strip module 50 and a central control component 20. The central control component 20 is housed in a through-slot structure 11. The light strip module 50 is disposed on the end face of the frame structure 10 and electrically connected to the central control component 20, so that the light strip module 50 can obtain signals from the central control component 20 and display images.

[0052] In an optional embodiment, the upper end face of the strip frame is provided with a receiving groove 12, and a slot structure 13 is connected between the receiving groove 12 and the through groove structure 11. The light strip module 50 is received in the receiving groove 12 and electrically connected to the central control component 20 through the slot structure 13.

[0053] For example, the central control component 20 is provided with a first connector, and the light strip module 50 is provided with a second connector. The first connector passes through the slot structure 13 and is then plugged into the second connector to realize signal transmission and power supply between the central control component 20 and the light strip module 50.

[0054] In an optional embodiment, the LED light strip also includes a baffle assembly 40, which is disposed at the openings on both sides of the through-slot structure 11 and allows the cable 60 in the through-slot structure 11 to pass through the baffle assembly 40 for signal and / or power connection to the outside.

[0055] In an optional embodiment, the end face of the first support member 31 is lower than the end faces on both sides of the frame structure 10 so that the potting compound 3311 can be accommodated in the potting groove 36. The baffle assembly 40 covers the outside of the first support member 31 to ensure the overall appearance of the LED light strip.
