Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to an LED display with an auxiliary heat dissipation and ventilation structure. Background Technology

[0002] An LED display screen is a display device that controls semiconductor light-emitting diodes. It is generally composed of a large number of light-emitting diodes. When working, it relies on the on and off of LED light sources to display images. LED displays can be used to display various information such as images, text, graphics, animations, videos, and video signals. Therefore, LED displays have developed rapidly. However, since LED displays convert electrical energy into light energy when working, LEDs inevitably generate some heat when emitting light. Over a long period of use, this will cause the LED light output to continuously decrease, resulting in light decay. It is also prone to color shift, causing color distortion, which will seriously affect the lifespan, performance, and reliability of LEDs. Utility Model Content

[0003] The purpose of this invention is to provide an LED display screen with an auxiliary heat dissipation and ventilation structure to solve the problem mentioned in the background art that prolonged heating of LEDs affects their lifespan, light decay, and color distortion.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an LED display screen with an auxiliary heat dissipation and ventilation structure, comprising a mounting frame, a screen body being inserted and installed inside the mounting frame, and the screen body engaging with the mounting frame; a back shell being inserted and installed on the side of the mounting frame away from the screen body, and a control motherboard being fixedly installed inside the back shell; an insertion port being provided on one outer surface of the mounting frame, and the insertion port on the outer surface of the mounting frame being connected to the control motherboard; a heat dissipation rib being snapped into the inner side of the mounting frame; and an auxiliary heat dissipation mechanism being provided between the mounting frame and the heat dissipation rib. This auxiliary heat dissipation mechanism facilitates passive heat dissipation of the screen body, enabling the screen body to dissipate heat and thus extending its service life.

[0005] Preferably, the auxiliary heat dissipation mechanism includes: a heat dissipation silicone pad, which is fixed to one side of the outer surface of the screen body. The heat dissipation silicone pad is located inside the mounting frame, and the mounting frame is engaged with one end of the heat dissipation rib. The outer surface of the heat dissipation rib is in contact with the outer surface of the heat dissipation silicone pad. There is a gap between the heat dissipation rib and the control motherboard, and a gap between the control motherboard and the back cover.

[0006] By adopting the above technical solution, the screen body can be easily fixed, and the heat dissipation silicone pad and heat dissipation fins can be easily installed. The heat generated by the screen body during operation can be conducted to the outer surface of the heat dissipation fins through the heat dissipation silicone pad, increasing the heat dissipation area of ​​the screen body. At the same time, it can facilitate the installation, fixing and maintenance of the screen body, heat dissipation silicone pad and heat dissipation fins.

[0007] Preferably, one end of the back shell is inserted into the outer surface of the mounting frame, and one end of the mounting frame is engaged with the back shell, and the outer surface of the back shell is in contact with the outer surface of the heat dissipation fins. A screw is provided between the back shell and the mounting frame, and the outer surfaces of the mounting frame and the back shell are in contact with the outer surfaces of the screws. One end of the heat dissipation fins is connected to the screw.

[0008] Using the above technical solution, the back cover can be easily snapped onto the outer surface of the mounting frame, and the screen body and heat dissipation fins are fixed by the back cover, reducing the use of screws and making disassembly and maintenance easier.

[0009] Preferably, an intake fan is uniformly fixedly installed on one end of the outer surface of the back shell, and a ventilation circulation mechanism is provided on the outer surface of the back shell to improve the heat dissipation of the screen body.

[0010] By adopting the above technical solution, the use of an intake fan in conjunction with heat dissipation fins allows heat to be carried away by the airflow more quickly, further improving the heat dissipation efficiency of the screen body during operation.

[0011] Preferably, the ventilation circulation mechanism includes: ventilation openings, which are evenly arranged on the outer surface of the back shell away from the intake fan, and a filter screen is inserted into the outer surface of the back shell, and the outer surface of the filter screen is in close contact with the outer surface of the back shell.

[0012] By adopting the above technical solution, the air drawn into the mounting frame by the intake fan can be filtered through the filter screen inserted on the outer surface of the back shell, reducing the short circuit and heat dissipation impact caused by dust entering the mounting frame.

[0013] Preferably, a bracket is rotatably mounted on the outer surface of the back cover near the vent, and the pivot of the bracket passes through the inner outer surface of the back cover. A gear is fixedly mounted on the outer surface of one side of the pivot of the bracket. An elastic sliding mechanism is provided between the back cover and the bracket. The elastic sliding mechanism enables the back cover to be positioned after rotation, allowing people to view the screen body more comfortably.

[0014] By adopting the above technical solution, the angle and position of the screen body can be adjusted, making it more comfortable for users to use and view the screen body.

[0015] Preferably, the elastic sliding mechanism includes: an insert plate, which is slidably installed inside the back shell, and a spring is provided between the back shell and the insert plate. One end of the insert plate located outside the back shell is engaged with a gear. A base is inserted inside the insert frame, and the base is designed to be inclined. One end of the base located inside the insert frame has a locking groove, and the locking groove is engaged with the insert frame.

[0016] Using the above technical solution, the spring pushes the insert plate, allowing it to snap into the outer surface of the gear. When it is necessary to change the angle between the screen body and the back cover, the back cover can be adjusted directly by flipping it.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the LED display screen with an auxiliary heat dissipation and ventilation structure:

[0018] 1. The heat dissipation silicone pad can conduct the heat generated by the screen body during operation to the outer surface of the heat dissipation fins, thereby increasing the heat dissipation area of ​​the screen body. At the same time, during installation, the screen body is inserted into the inside of the mounting frame, and the heat dissipation fins are snapped into one end of the mounting frame. This makes it easier to install and fit the screen body, heat dissipation silicone pad and heat dissipation fins together. It can also reduce the light decay, color distortion and lifespan reduction caused by the inability to dissipate heat in time during long-term operation of the screen body.

[0019] 2. When the temperature is too high and the passive heat dissipation efficiency of the heat sink cannot be met, the intake fan will start to draw cool air from outside into the mounting frame. The air is filtered to remove dust, preventing dust from entering the mounting frame and affecting the heat dissipation of the heat sink and the motherboard. The cool air can pass through the heat sink and the motherboard and carry away the heat, while the hot air is exhausted from the vents, improving the heat dissipation efficiency of the screen itself.

[0020] 3. After installing the screen body, thermal pad, and heat dissipation fins into the mounting frame, the back cover can be inserted and snapped into the mounting frame. The back cover limits and fixes the screen body. Then, screws are screwed in so that the screws can pass through the mounting frame and the back cover and connect and fix to the heat dissipation fins. By having the screws pass through the mounting frame and connect to the heat dissipation fins, the screen body, back cover, and heat dissipation fins can be fixed and restrained at the same time, reducing the use of screws and making it easier to remove them for subsequent maintenance and inspection.

[0029] 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.

[0030] Please see Figure 1-7 This utility model provides a technical solution: an LED display screen with an auxiliary heat dissipation and ventilation structure, including a mounting frame 1, a screen body 2 is inserted and installed inside the mounting frame 1, and the screen body 2 is engaged with the mounting frame 1. A back shell 3 is inserted and installed on the side of the mounting frame 1 away from the screen body 2, and a control motherboard 6 is fixedly installed inside the back shell 3. A socket is provided on the outer surface of one side of the mounting frame 1, and the socket on the outer surface of the mounting frame 1 is connected to the control motherboard 6. A heat dissipation rib 5 is snapped into the inner side of the mounting frame 1. An auxiliary heat dissipation mechanism is provided between the mounting frame 1 and the heat dissipation rib 5. The auxiliary heat dissipation mechanism facilitates passive heat dissipation of the screen body 2, allowing the screen body 2 to dissipate heat and improve the service life of the screen body 2.

[0031] By installing the control motherboard 6 on the outside of the back cover 3, the back cover 3 can be separated from the screen body 2. The gap between the back cover 3 and the control motherboard 6 allows external air to enter the mounting frame 1, which can maximize the heat dissipation of the control motherboard 6.

[0032] The auxiliary heat dissipation mechanism includes: a heat dissipation silicone pad 4, which is attached and fixed to one side of the outer surface of the screen body 2. The heat dissipation silicone pad 4 is located inside the mounting frame 1, and the mounting frame 1 is engaged with one end of the heat dissipation rib 5. The outer surface of the heat dissipation rib 5 is attached to the outer surface of the heat dissipation silicone pad 4. There is a gap between the heat dissipation rib 5 and the control motherboard 6, and there is a gap between the control motherboard 6 and the back cover 3.

[0033] The heat dissipation ribs 5 maximize the heat dissipation area of ​​the mounting frame 1. The heat dissipation silicone pad 4 adheres to the screen body 2, allowing the heat generated by the screen body 2 during operation to be better transferred to the heat dissipation ribs 5. The engagement of the heat dissipation ribs 5 with the mounting frame 1 makes the installation and attachment of the heat dissipation silicone pad 4 and the heat dissipation ribs 5 easier. It also allows the heat generated by the screen body 2 during operation to be dispersed, reducing light decay, color distortion and lifespan reduction of the screen body 2 caused by heat generation.

[0034] One end of the back shell 3 is inserted into the outer surface of the mounting frame 1, and one end of the mounting frame 1 is engaged with the back shell 3. The outer surface of the back shell 3 is in contact with the outer surface of the heat dissipation fin 5. A screw is provided between the back shell 3 and the mounting frame 1, and the outer surfaces of the mounting frame 1 and the back shell 3 are in contact with the outer surfaces of the screw. One end of the heat dissipation fin 5 is connected to the screw.

[0035] By engaging and inserting the back cover 3 into the mounting frame 1, and simultaneously connecting and fixing the back cover 3 and the mounting frame 1 with screws, and by screwing in the connection between the screws and the heat dissipation fins 5, the heat dissipation fins 5 can be fixed. This reduces the number of screws required when assembling the back cover 3 and the mounting frame 1, making disassembly more convenient and quick.

[0036] An intake fan 7 is uniformly fixedly installed on one end of the outer surface of the back cover 3, and a ventilation circulation mechanism is provided on the outer surface of the back cover 3 to improve the heat dissipation of the screen body 2.

[0037] By activating the intake fan 7, external air can be drawn into the mounting frame 1, and the drawn air can pass through the heat dissipation fins 5 and the control motherboard 6 to remove the heat generated during operation, thereby improving the heat dissipation effect of the screen body 2 and the control motherboard 6, and allowing hot air to be discharged from the mounting frame 1 through the vent 9.

[0038] The ventilation circulation mechanism includes: ventilation openings 9, which are evenly arranged on the outer surface of the back shell 3 away from the intake fan 7, and a filter screen 8 is inserted into the outer surface of the back shell 3, and the outer surface of the filter screen 8 is tightly attached to the outer surface of the back shell 3.

[0039] The filter 8 inserted on the outer surface of the back cover 3 can effectively filter dust in the air, preventing dust from entering the interior of the mounting frame 1. This prevents the heat sink 5 and the control motherboard 6 from being affected by dust, thus avoiding short circuits and reduced heat dissipation. At the same time, the filter 8 can be easily removed for cleaning.

[0040] A bracket 10 is rotatably mounted on the outer surface of the back cover 3 near the vent 9, and the pivot of the bracket 10 passes through the inner outer surface of the back cover 3. A gear 12 is fixedly mounted on the outer surface of the pivot on one side of the bracket 10. An elastic sliding mechanism is provided between the back cover 3 and the bracket 10. The elastic sliding mechanism enables the back cover 3 to be positioned after rotation, allowing people to view the screen body 2 more comfortably.

[0041] Through the bracket 10 and the gear 12, when the back shell 3 rotates, the spring 14 can push the insert plate 13 to fit tightly against the gear 12, so that the gear 12 can engage with the insert plate 13, thereby fixing and positioning the angle of the mounting frame 1, the screen body 2 and the back shell 3, and allowing the angle and orientation of the mounting frame 1, the screen body 2 and the back shell 3 to be adjusted at will.

[0042] The elastic sliding mechanism includes: a plate 13, which is slidably installed inside the back shell 3, and a spring 14 is provided between the back shell 3 and the plate 13. One end of the plate 13 located outside the back shell 3 is engaged with a gear 12. A base 11 is inserted inside the insert frame 10, and the base 11 is designed to be inclined. One end of the base 11 located inside the insert frame 10 is provided with a snap-fit ​​groove 15, and the snap-fit ​​groove 15 is engaged with the insert frame 10.

[0043] The latching groove 15 allows the bracket 10 to be inserted into and fixed firmly to the base 11. Separating the base 11 from the bracket 10 makes it easy to store the screen as a whole and facilitates transportation and movement.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
