Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular discloses an ultra-thin MiniLED display screen profile frame structure. Background Technology

[0002] With the continuous advancement of display technology, Mini LED displays, with their superior performance such as high brightness, high contrast, and wide color gamut, have been widely used in commercial displays, high-end televisions, and other fields. To adapt to more complex installation environments and pursue the ultimate visual experience, the market has placed higher demands on the thinner and lighter design of Mini LED displays.

[0003] However, the ultra-thin design of displays inevitably leads to extreme compression of the bezel space, resulting in a series of technical challenges: First, heat dissipation efficiency becomes a bottleneck. Mini LED chips have a high density and generate a large amount of heat during operation. The ultra-thin bezel greatly limits the space for heat dissipation design, and traditional passive cooling methods have limited effectiveness. If heat cannot be dissipated in a timely and effective manner, it will directly lead to an increase in screen temperature, seriously affecting the luminous efficacy, lifespan, and display stability of the LED chips. Second, waterproof reliability is difficult to guarantee. Especially for outdoor or environmentally variable applications, waterproofing is crucial for the stable operation of the display. Within the narrow bezel space, the reliability of traditional waterproofing solutions (such as a single rubber ring seal) is reduced. At the same time, the ventilation channels that must be set up for heat dissipation become potential pathways for rainwater infiltration. How to effectively prevent rainwater, especially vertical dripping or splashing water, from entering the screen under high heat dissipation requirements is a significant challenge in the design of ultra-thin display bezels.

[0004] Therefore, there is an urgent need in this field for an innovative profile frame structure that can achieve both efficient heat dissipation and high-reliability waterproofing while being ultra-thin. Utility Model Content

[0005] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a frame structure that can achieve both efficient heat dissipation and high-reliability waterproofing while being ultra-thin.

[0006] To achieve the above objectives, this utility model discloses an ultra-thin MiniLED display screen frame structure, comprising a frame body and a back cover. The frame body has a first mounting groove and a second mounting groove on each side. The external display screen and the back cover are mounted on the frame body via the first and second mounting grooves, respectively. The frame body has a hollow cavity structure in its cross-section, forming a heat dissipation airflow channel that isolates the display screen from the internal and external environments. The frame body has an exhaust vent and an outlet vent connected to the heat dissipation airflow channel. Integrating support, installation, heat dissipation, and isolation into a single profile achieves extreme simplification and compactness, forming the cornerstone of the "ultra-thin" design. This creates conditions for forced convection within the hollow cavity, upgrading the traditional "heat conduction" heat dissipation mode of the frame to a "convection" mode, resulting in a qualitative leap in heat dissipation efficiency. The hollow cavity effectively blocks external dust and moisture from directly invading the screen interior, improving reliability.

[0007] Furthermore, the exhaust vent is located on the inner side wall of the frame body, and the air outlet is located on the outer side wall of the frame body. Hot air is drawn in from the inside (inner side) of the screen body, and discharged from the outside (outer side) of the screen body through the heat dissipation airflow channel, forming an efficient "side-in-side-out" or "inner-in-out" linear heat dissipation path, achieving the shortest and most efficient heat dissipation path.

[0008] Furthermore, the exhaust vents and outlet vents are vertically staggered. Even if rainwater enters from the outer outlet vent, it will impact the inner wall of the staggered duct due to gravity and fall down, unable to directly pass through the inner exhaust vent vent into the screen. Although there is some resistance to airflow, air can still pass through smoothly, ensuring waterproofing without affecting the core heat dissipation function, thus resolving the inherent contradiction between heat dissipation and waterproofing.

[0009] Furthermore, the frame body is integrally bent and formed. There are no seams or welds, resulting in good overall consistency and ensuring the flatness of the splicing surfaces and the overall structural strength.

[0010] Furthermore, a third mounting groove is provided within the second mounting groove, and the wall of the third mounting groove is provided with a drain groove for draining liquid. This structure can effectively collect the very small amount of water or condensation that may seep in along the gaps in the back cover and actively guide it to the bottom of the screen for discharge through the drain groove. This upgrades the waterproofing from "waterproof" to "waterproof and able to drain quickly even if water does get in," greatly improving waterproof reliability.

[0011] Furthermore, the rear cover includes a back plate portion and bent portions that bend from both ends of the back plate portion. The bent portions extend into a third mounting groove, and the back plate portion abuts against the bottom of the second mounting groove. The concave structure of the rear cover fastens to the rear side of the frame body to form a labyrinth fit, and the back plate portion and the bottom of the second mounting groove form a main sealing surface to enhance waterproof performance.

[0012] Furthermore, the bottom of the second mounting groove is provided with a sealing groove, and a waterproof rubber ring is installed inside the sealing groove. The waterproof rubber ring is used to seal the gap between the second mounting groove and the back cover. This achieves a static seal, completely blocking the last possible channel for water leakage between the back cover and the frame, serving as the "last line of defense" for waterproofing. The pre-placed sealing groove at the bottom of the ultra-thin groove enables precise positioning and reliable compression of the rubber ring, avoiding seal failure caused by rubber ring displacement or uneven compression.

[0013] Furthermore, the frame body has male and female grooves for splicing at both ends. The splicing structure is directly designed and integrally formed with the core profile, ensuring splicing accuracy and strength.

[0014] Furthermore, the exhaust vents are provided in multiple sets, with these sets evenly spaced along the length of the frame body. This ensures that the cooling airflow can evenly draw heat from the entire back of the display screen, avoiding localized overheating areas and achieving uniform heat dissipation.

[0015] Furthermore, the inner wall of the frame body is provided with a mounting boss for mounting a cooling fan, and the exhaust vent is opened on the mounting boss. Through this local reinforcement structure of the mounting boss, a flat and stable mounting base is provided for the cooling fan, and the exhaust vent is integrated on the boss.

[0016] The beneficial effects of this utility model: One of the core innovations of this utility model lies in designing the cross-section of the frame body as a hollow cavity structure, cleverly forming a highly efficient heat dissipation airflow channel. By setting an exhaust port on the inner side wall and cooperating with a cooling fan, the hot air accumulated inside the screen can be actively drawn into the channel and quickly discharged through the exhaust port on the outer side wall. This "active intake and directional exhaust" heat dissipation mode greatly improves heat dissipation efficiency, ensuring that the Mini LED display can maintain stable low-temperature operation even in its ultra-thin state;

[0017] By employing a one-piece bending and forming technology to manufacture the frame body, the seams and accumulated errors caused by multi-segment splicing are completely eliminated, ensuring the integrity of the frame and extremely high dimensional accuracy. This not only results in uniform gaps and a flat image when splicing multiple screens, but also significantly improves the bending and torsional rigidity of the profile, fundamentally avoiding display quality problems caused by structural deformation;

[0018] By vertically offsetting the inner exhaust vents and outer air outlets, a physical barrier is formed within the heat dissipation duct. This "maze-like" structure effectively prevents external rainwater or splashes from directly entering the screen due to gravity, achieving the first layer of waterproof protection. A second layer of waterproof protection is formed by a sealing ring at the junction of the back cover and the frame, utilizing the unique combination of the concave back cover and the drainage channel. Even if a very small amount of moisture or condensation intrudes, it can be effectively collected and quickly drained downwards through the drainage channel, completely preventing moisture accumulation inside and ensuring more reliable waterproof performance.

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] Please see Figures 1 to 6As shown, this utility model discloses an ultra-thin MiniLED display screen frame structure, including a frame body 1 and a back cover 2. The frame body 1 has a first mounting groove 3 and a second mounting groove 4 on both sides. The external display screen and the back cover 2 are mounted on the frame body 1 via the first mounting groove 3 and the second mounting groove 4, respectively. The frame body 1 has a hollow cavity structure in its cross-section, forming a heat dissipation airflow channel 5 that isolates the internal and external environments of the display screen. The frame body 1 has an exhaust vent 6 and an outlet vent 7 connected to the heat dissipation airflow channel 5. By integrating support, installation, heat dissipation, and isolation into a single profile, this design achieves extreme simplification and compactness, forming the cornerstone of the "ultra-thin" design. It creates conditions for forced convection in the hollow cavity, upgrading the traditional "heat conduction" heat dissipation mode of the frame to a "convection" mode, resulting in a qualitative leap in heat dissipation efficiency. The hollow cavity effectively blocks external dust and moisture from directly invading the screen interior, improving reliability.

[0029] Specifically, this utility model provides an ultra-thin MiniLED display screen frame structure. Its core components are the frame body 1 and the back cover 2. The frame body 1 is preferably made of 6063 aluminum alloy, manufactured through an integrated bending process to ensure overall structural strength and precision. A first mounting groove 3 is provided on the side of the frame body 1 facing inwards from the display screen for securing and fixing the display screen. A second mounting groove 4 is provided on the side of the frame body 1 facing outwards for mounting the back cover 2. The cross-section of the frame body 1 is an overall closed hollow cavity structure, which constitutes the heat dissipation airflow channel 5 of this embodiment. An exhaust port 6 and an outlet port 7, connected to the heat dissipation airflow channel 5, are provided on the frame body 1.

[0030] The exhaust vent 6 is located on the inner side wall of the frame body 1, and the air outlet 7 is located on the outer side wall of the frame body 1. Hot air is drawn in from the inside (inner side) of the screen and discharged from the outside (outer side) of the screen through the heat dissipation airflow channel 5, forming an efficient "side-in-side-out" or "inner-in-out" linear heat dissipation path, achieving the shortest and most efficient heat dissipation path.

[0031] The exhaust vent 6 and the air outlet 7 are arranged in a staggered manner in the vertical direction. Even if rainwater enters from the outer air outlet 7, it will hit the inner wall of the staggered air duct due to gravity and fall down, and cannot directly pass through the inner exhaust vent 6 into the screen body. Although there is some resistance to airflow, air can still pass through smoothly. This ensures waterproofing without affecting the core heat dissipation function, thus solving the inherent contradiction between heat dissipation and waterproofing.

[0032] Specifically, the exhaust vent 6 is located on the inner side wall of the frame body 1, directly opposite the heat-generating area of ​​the display module. The air outlet 7 is located on the outer side wall of the frame body 1. A key design feature is that the exhaust vent 6 and air outlet 7 are vertically offset, and they are not directly opposite each other. This design creates a "Z"-shaped tortuous path within the heat dissipation airflow.

[0033] The frame body 1 is integrally bent and formed. There are no splicing welds, resulting in good overall consistency and ensuring the flatness of the splicing surface and the overall structural strength.

[0034] The second mounting groove 4 contains a third mounting groove 8, and the wall of the third mounting groove 8 is provided with a drain groove 9 for draining liquid. This structure can effectively collect the very small amount of water or condensate that may seep in along the gaps in the back cover 2, and actively guide it to the bottom of the screen for discharge through the drain groove 9. Upgrading from "waterproof" to "waterproof and able to drain quickly after water ingress," this greatly improves waterproof reliability.

[0035] The rear cover 2 includes a back plate portion 10 and bent portions 11 that bend from both ends of the back plate portion 10. The bent portions 11 extend into the third mounting groove 8, and the back plate portion 10 abuts against the bottom of the second mounting groove 4. The concave structure of the rear cover 2 is fastened to the rear side of the frame body 1 to form a labyrinth fit, and the back plate portion 10 and the bottom of the second mounting groove 4 form the main sealing surface to enhance waterproof performance.

[0036] Specifically, the back cover 2 is composed of a back plate portion 10 and bent portions 11 formed by vertical bending from both sides of the back plate portion 10, which together form a concave structure. During installation, the bent portions 11 are aligned and inserted into the third mounting groove 8 until the back plate portion 10 is tightly against the bottom of the second mounting groove 4.

[0037] The bottom of the second mounting groove 4 is provided with a sealing groove 12, and a waterproof rubber ring 13 is provided inside the sealing groove 12. The waterproof rubber ring 13 is used to seal the gap between the second mounting groove 4 and the back cover 2. This achieves a static seal, completely blocking the last channel for water to seep between the back cover 2 and the frame, serving as the "last line of defense" for waterproofing. The pre-placed sealing groove 12 in the bottom of the ultra-thin groove enables precise positioning and reliable compression of the rubber ring, avoiding seal failure caused by rubber ring displacement or uneven compression.

[0038] The frame body 1 has male and female grooves for splicing at both ends. The splicing structure is directly designed and integrally formed with the core profile, ensuring splicing accuracy and strength.

[0039] The exhaust vents 6 are provided in multiple sets, and these sets of exhaust vents 6 are equally spaced along the length of the frame body 1. This ensures that the heat dissipation airflow can evenly draw heat from the entire back of the display screen, avoiding localized overheating areas and achieving uniform heat dissipation.

[0040] Preferably, in this embodiment, the exhaust vent 6 is provided with three sets.

[0041] The inner sidewall of the frame body 1 is provided with a mounting boss for mounting a cooling fan, and the exhaust port 6 is opened on the mounting boss. Through the local reinforcement structure of the mounting boss, a flat and stable mounting base is provided for the cooling fan, and the exhaust port 6 is integrated on the boss.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
