Description

A modular LCD display terminal driver power supply with easy heat dissipation Technical Field

[0001] This utility model relates to the field of driving power supply technology, specifically to a modular LCD display terminal driving power supply that facilitates heat dissipation. Background Technology

[0002] Modular LCD displays mainly involve arranging and combining multiple LCD displays, connecting them with a bracket to form a large display for use. This increases the display area and provides better display effects and impact. A driving power supply is required when using modular LCD display terminals.

[0003] Publication No. CN207531260U discloses a heat dissipation device for an LED display module driver power supply. It includes a dustproof mesh to prevent dust from entering the heat sink and the LED display module driver power supply, solving the problem of excessive dust damaging these components. Dust prevention also helps extend the lifespan of the heat sink and LED display module driver power supply. A protective cover effectively protects the wiring board, addressing the issue of exposed wiring boards being easily covered by dust during use and preventing interference from external dust. Screws, upper nuts, and lower nuts facilitate heat sink replacement, allowing for easy replacement in case of damage and preventing internal heat sink failure that could hinder heat dissipation. A drying box absorbs moisture from the heat sink and LED display module driver power supply, solving the problem of humid air damaging the internal circuitry and preventing the LED display module driver power supply from malfunctioning due to moisture. However, this patent still has the following problems in practical use:

[0004] Although the LED display module driver power supply heat dissipation device prevents dust from entering the heat sink and the LED display module driver power supply by setting up a dustproof screen, dust will accumulate on the dustproof screen during long-term use. If the dust on the dustproof screen cannot be cleaned, the internal heat cannot be dissipated quickly, thus affecting the heat dissipation quality of the driver power supply.

[0005] Therefore, a modular LCD display terminal driver power supply with easy heat dissipation is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a modular LCD display terminal driver power supply that facilitates heat dissipation, in order to solve the problem mentioned in the background art where dust accumulates on the dustproof mesh during long-term use, making it impossible to clean the dust and causing internal heat to be unable to dissipate quickly, thus affecting the heat dissipation quality of the driver power supply.

[0011] The protective base is symmetrically equipped with ventilation covers on both sides, and collection boxes are symmetrically installed at the bottom of the ventilation covers.

[0012] The ventilation hood has symmetrically installed circulating grooves on both sides inside, and a first sprocket limiting cover is symmetrically installed on the top of the ventilation hood.

[0013] Preferably, a first cleaning motor is fixedly installed on one side inside the first sprocket limiting cover, and a first sprocket transmission assembly is fixedly connected to the output end of the first cleaning motor.

A first cleaning brush is fixedly connected to the end of the connecting spring. Limiting sliders are symmetrically installed on both sides of the first cleaning brush, and the limiting sliders are slidably connected to the ventilation cover through a circulating groove.

[0015] Preferably, a plurality of ejector springs are fixedly installed on the bottom inner side of the ventilation hood, a first dustproof net is attached to the top of the ejector springs, and spring buckles are symmetrically engaged on one side of the first dustproof net.

[0017] Preferably, the magnetic hooks are symmetrically arranged on the front of the protective cover, and the magnetic hooks are magnetically connected to the first magnetic block.

When a certain amount of dust is adsorbed on the surface of the first dustproof net, the first cleaning motor is started to drive the first sprocket transmission assembly and the first cleaning threaded rod to rotate, so that the first cleaning threaded sleeve drives the cleaning bracket to move up and down. Under the elastic force of the connecting spring, the first cleaning brush can be extended and retracted, so that the first cleaning brush fits the surface of the first dustproof net, improving the cleaning effect of the first dustproof net. Through the feature of the limit slider sliding connection with the circulating slide groove, the first cleaning brush can clean from top to bottom in one direction, thereby improving the cleaning effect of the first dustproof net. By setting the first cleaning brush on both sides of the first dustproof net, dust can be prevented from entering the interior of the first dustproof net, thus affecting the cleaning effect of the first dustproof net. By setting the ejection spring and spring buckle, the first dustproof net can be quickly installed and removed, which is convenient for cleaning and replacing the first dustproof net.

[0021] 2. By setting up a heat dissipation mechanism, the protective cover can be closed using the connecting hinge and magnetic hook, thus providing safety protection for the drive power supply body. The cooling fan enables rapid heat dissipation of the drive power supply body. By starting the second cleaning motor, the second sprocket transmission assembly and the second cleaning threaded rod are rotated, causing the second cleaning threaded sleeve to move the second cleaning brush. In conjunction with the cooling fan, air is blown from the inside out, improving the cleaning effect of the second dust screen. The second dust screen can be installed and removed using mounting bolts. Attached Figure Description

[0032] Working Principle: Before using this modular LCD display terminal driver power supply with easy heat dissipation, it is necessary to check the overall condition of the device to ensure normal operation. As shown in Figures 1-6, firstly, the protective cover 201 is closed using the connecting hinge 202 and magnetic hook 205, thereby providing safety protection for the driver power supply body 102. The cooling fan 204 is used to quickly dissipate heat from the driver power supply body 102. By starting the second cleaning motor 208, the second sprocket transmission assembly 209 and the second cleaning threaded rod 210 are rotated, causing the second cleaning threaded sleeve 211 to drive the second cleaning brush 212 to move. This, combined with the cooling fan 204, blows air from the inside out, improving the cleaning effect of the second dustproof net 203. The second dustproof net 203 can be installed and removed using the mounting bolts 213. Secondly, the ventilation cover 104 is used to ventilate the protective base 101, while the first dustproof net 117 provides dust protection for the protective base 101. When the first dustproof net 117... When a certain amount of dust is adsorbed on the surface, the first cleaning motor 108 is started, driving the first sprocket transmission assembly 109 and the first cleaning threaded rod 110 to rotate. This causes the first cleaning threaded sleeve 111 to drive the cleaning bracket 112 to move up and down. Under the elastic force of the connecting spring 113, the first cleaning brush 114 can extend and retract, allowing it to fit against the surface of the first dustproof net 117, thus improving the cleaning effect of the first dustproof net 117. Through the sliding connection between the limiting slider 115 and the circulating groove 106, the first cleaning brush 114 cleans unidirectionally from top to bottom, thereby improving the cleaning effect of the first dustproof net 117. By setting the first cleaning brush 114 on both sides of the first dustproof net 117, dust can be prevented from entering the interior of the first dustproof net 117, thus affecting its cleaning effect. By setting the ejection spring 116 and the spring buckle 118, the first dustproof net 117 can be quickly installed and removed, facilitating the cleaning and replacement of the first dustproof net 117.
