Description

Technical Field

[0001] This utility model relates to the field of billboard technology, and in particular to an LED billboard with good heat dissipation. Background Technology

[0002] LED billboards use a series of LED beads to form the name of a store, making them more visible at night and enhancing their aesthetics. However, when using LED billboards, the LED beads need to be turned on for extended periods. This prolonged use generates a lot of heat, and the accumulated heat can affect the lifespan of the internal electronic components and circuitry.

[0003] Therefore, when using LED billboards, heat dissipation vents are usually provided on the side of the billboard. When placed outdoors, the outside air can dissipate heat through the heat dissipation vents. However, these heat dissipation vents are small in size. Although the outside air naturally enters the heat dissipation vents, when the outside airflow is small, less airflow enters the heat dissipation vents, resulting in poor heat dissipation. To address this issue, we propose an LED billboard with better heat dissipation to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing an LED billboard with good heat dissipation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An LED billboard with good heat dissipation includes a billboard body, a placement groove is provided in the middle of the interior of the billboard body, ventilation grooves are provided at both the upper and lower ends of the placement groove, the ventilation grooves are connected to the outside, protective filters are provided on both the upper and lower sides of the billboard body, and a mounting shell is provided in the middle of the interior of the placement groove, the upper and lower ends of the mounting shell are open, and multiple sets of rotating fan blades are provided inside the mounting shell. This allows the rotating fan blades inside the housing to rotate, thus enabling the fan blades to drive airflow into the interior of the light sign body for better heat dissipation.

[0006] Preferably, the output shaft of the rotating fan blade extends through the mounting housing to the outside, and a transmission wheel is provided at the end of the output shaft of the rotating fan blade; This makes it easier for the fan blades to rotate, thus allowing them to better drive the external airflow into the interior of the light sign body.

[0007] Preferably, a transmission belt is sleeved on the outside of the transmission wheel, and the transmission belt enables multiple sets of transmission wheels to drive each other. Multiple sets of rotating fan blades can rotate synchronously, thereby allowing airflow to enter the interior of the light sign body more effectively.

[0008] Preferably, the side wall of the mounting housing is provided with a protective cover, which covers the outside of the drive wheel and the drive belt; It can protect the transmission of the drive belt and drive pulley, preventing the drive pulley and drive belt from shifting during rotation.

[0009] Preferably, heat dissipation fins are provided on both the upper and lower sides of the placement slot, and the heat dissipation fins are located on the upper and lower sides of the mounting shell; This allows airflow to come into contact with the heat dissipation fins, thus improving heat dissipation.

[0010] Preferably, blocking blocks are inserted inside the upper and lower sides of the light sign body, the blocking blocks extend into the interior of the light sign body, a support shaft is provided inside the light sign body, the end of the support shaft is inserted into the end of the blocking block, a connecting block is provided at the top of the blocking block, a sliding slot is opened at the top of the light sign body, and the connecting block extends to the outside through the sliding slot. The blocking block can be moved by sliding the connecting block, so that the protective filter can be disassembled and cleaned, avoiding clogging of the protective filter after long-term use, and making the filtration effect of the protective filter better.

[0011] Preferably, a support spring is sleeved on the outside of the support shaft, and the end of the blocking block is inclined. During installation, the protective filter can be pressed against the inclined surface of the blocking block, causing the blocking block to move along the inclined surface. Then, the blocking block is restored by the support spring, making the installation of the protective filter more convenient.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model can make the rotating fan blades rotate, so that the rotating fan blades drive the airflow through the ventilation slot into the interior of the placement slot. At the same time, the airflow comes into contact with the heat dissipation fins to exchange heat, so that the airflow efficiency after passing through the light sign body is better, and the heat dissipation effect is further improved.

[0013] 2. This utility model allows external impurities to be filtered by the protective filter, thereby preventing impurities from entering the interior of the light sign body and affecting its normal use. At the same time, the connecting block can be pulled to move the blocking block, making it convenient to disassemble and clean the protective filter, resulting in better performance of the protective filter in subsequent use.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 The LED billboard shown has a good heat dissipation design. A placement slot 2 is formed in the middle of the main body 1. Ventilation slots 3 are formed at both the top and bottom of the main body 1, allowing the placement slot 2 to communicate with the outside. Recesses are also formed at both the top and bottom of the main body 1, and protective filters 4 are placed inside these recesses. These filters block dust from falling into the placement slot 2. A mounting housing 5 is then fixedly installed in the middle of the placement slot 2. The mounting housing 5 has openings at both the top and bottom. Multiple sets of rotating fan blades 6 are movably installed inside the mounting housing 5. The output shaft of the rotating fan blades 6 extends through the interior of the mounting housing 5 to the outside. A transmission wheel 7 is then fixedly installed on the output shaft of the rotating fan blades 6. A transmission belt 8 is sleeved on the outside of the transmission wheel 7, so that the multiple sets of transmission wheels 7 can be driven by the transmission belt 8. A protective cover 9 is then fixedly installed on the side wall of the mounting housing 5, so that the protective cover 9 covers and protects the transmission wheel 7 and the transmission belt 8. Finally, multiple sets of heat dissipation fins 10 are fixedly installed on both the upper and lower sides inside the placement slot 2. The heat dissipation fins 10 are located at the upper and lower ends of the mounting housing 5.

[0018] For a detailed description of the protective filter 4 in this embodiment, please refer to [link / reference]. Figure 2 and Figure 4The light sign body 1 has grooves on the upper and lower sides, and a blocking block 11 is placed inside the grooves. A support shaft 12 is fixedly installed inside the grooves, with the end of the support shaft 12 inserted into the blocking block 11. A support spring 13 is sleeved on the outside of the support shaft 12. One end of the support spring 13 is fixedly connected to the end inside the groove of the light sign body 1, and the other end of the support spring 13 is fixedly connected to the end of the blocking block 11. A connecting block 14 is fixedly installed on the top of the blocking block 11, so that sliding slots 15 are opened at both the upper and lower ends of the light sign body 1, and the end of the connecting block 14 extends into the sliding slot 15. The end of the blocking block 11 is inclined.

[0019] Working principle: When in use, the rotation of the fan blade 6 drives the external airflow to circulate inside the light sign body 1, so that the airflow comes into contact with the heat dissipation fins 10, thereby better dissipating heat. At the same time, the protective filter 4 can filter the impurities contained in the airflow, thereby preventing impurities from entering the interior of the light sign body 1 and affecting the normal use of its original electronic components.

[0020] When the protective filter 4 becomes clogged due to excessive impurities, the connecting block 14 can be pulled to move the blocking block 11, causing the blocking block 11 to detach from the top of the protective filter 4. At this point, the protective filter 4 can be disassembled and cleaned. After cleaning, it can be placed directly into the grooves on both sides of the light sign body 1. Then, the inclined surface of the blocking block 11 is pressed to move the blocking block 11. Subsequently, the supporting spring 13 drives the blocking block 11 to return to its original position, allowing the blocking block 11 to move back above the protective filter 4 to complete the limit position, thus completing the installation of the protective filter 4.
