Description

Technical Field

[0001] This utility model relates to the field of LED display module technology, specifically an LED display module structure. Background Technology

[0002] LED display modules are one of the basic components of an LED display screen. LED beads are the core components that emit light in the module. Common types include monochrome, dual-color, and RGB tri-color beads. Monochrome beads can only emit one color of light, such as red, green, or blue; dual-color beads can emit two colors of light; and RGB beads are composed of red, green, and blue LEDs, which can produce various colors by mixing them in different proportions. Circuit boards are used to fix the LED beads and provide them with circuit connections. Common types include PCBs. Circuit boards also integrate driver circuits and control circuits. The driver circuit is responsible for providing the appropriate current and voltage to the LED beads to ensure their normal light emission, while the control circuit receives external signals and controls the on / off state and brightness of each LED bead to display images or text. They are widely used in outdoor billboards, shopping mall advertising screens, subway station advertising screens, etc., and can attract viewers' attention with high-brightness, high-definition images and videos to display advertising content.

[0003] Currently, when LED display modules experience display abnormalities and require repair or replacement, a thin metal sheet is inserted into the gap between two adjacent LED display modules to pry out the problematic module, or a height difference is created by squeezing the gap before removing the problematic module. Large gaps during this process can easily damage the module. Furthermore, some LED display modules have poor heat dissipation. When the power of an LED display is high, it generates a large amount of heat during operation. If this heat is not dissipated in time, it may cause the LED chips to overheat, affecting their lifespan and performance, and potentially even damaging the display screen. Utility Model Content

[0004] In view of the problems in the existing technology, such as the inconvenience of disassembling LED display modules, which can easily lead to damage to the modules, and the poor heat dissipation performance of LED displays when the power is high, which affects their lifespan and performance, this utility model provides an LED display module structure.

[0005] This utility model discloses an LED display module structure, including a housing, a PCB panel for mounting LED beads is installed on the outer side of the housing, a reinforcing frame and a heat dissipation mechanism to improve the heat dissipation performance of the PCB panel are installed inside the housing, and a disassembly and assembly mechanism is installed at each of the four corners on one side of the reinforcing frame to facilitate the disassembly of the entire module from the mounting frame.

[0006] Preferably, a disassembly groove is provided at the top outer edge of the outer casing to facilitate the removal of the outer casing from the frame with fingers.

[0007] Preferably, a connecting sleeve with an internal baffle is installed at each of the four edges of one side of the reinforcing frame. A threaded cylinder for matching the size and number of the connecting sleeves on the reinforcing frame is installed on the back of the PCB panel. The threaded cylinder on the PCB panel is inserted into the connecting sleeve from the other side of the reinforcing frame and then tightened with a bolt from the other end of the connecting sleeve.

[0008] Preferably, the disassembly and assembly mechanism is equipped with a telescopic rod, one end of which is fixedly installed at the corner of the reinforcing frame, and a magnet is fixedly installed at one end of the telescopic rod. A spring is sleeved on the outer ring surface of the telescopic joint of the telescopic rod, and the two ends of the spring are respectively fixedly installed between one side of the telescopic rod and the magnet. One end of the magnet extends 1 cm out of the inner side of the outer shell in the initial state.

[0009] Preferably, the reinforcement frame has multiple threaded holes at each of the four edges on one side. The heat dissipation mechanism includes a honeycomb heat dissipation plate and a heat dissipation metal mesh. The honeycomb heat dissipation plate and the heat dissipation metal mesh have through holes that match the size and number of the threaded holes. After the heat dissipation mechanism is placed inside the outer shell, it is tightened and fixed by bolts passing through the through holes of the honeycomb heat dissipation plate and the heat dissipation metal mesh and screwing them into the threaded holes on the reinforcement frame.

[0010] Preferably, each protruding edge of the honeycomb heat sink and the heat dissipation metal mesh is provided with an arc-shaped groove fitted onto the outer ring surface of the connecting sleeve at the center of its length, and right-angle grooves are provided at the four corners of the honeycomb heat sink and the heat dissipation metal mesh.

[0011] Preferably, the heat dissipation metal mesh is attached to the outer surface of the honeycomb heat sink, and four graphene heat-conducting plates are installed on the back of the honeycomb heat sink. The reinforcing frame has four heat dissipation slots 31 that match the size of the graphene heat-conducting plates. The graphene heat-conducting plates pass through the heat dissipation slots 31 on the reinforcing frame and are attached to the back of the PCB panel. The graphene heat-conducting plates, the honeycomb heat sink, and the heat dissipation metal mesh all have rectangular slots for exposing power interfaces, signal interfaces, and communication interfaces.

[0012] Preferably, an exhaust duct is installed at the center of the outer side of the heat dissipation metal mesh, and a cooling fan is installed inside the exhaust duct. A temperature sensor for monitoring the temperature of the back of the PCB panel is installed at the center of one side of the reinforcing frame. When the temperature sensor detects a temperature value greater than a set value, the cooling fan automatically shuts off, and when the temperature value is lower than the set value.

[0013] Compared with the prior art, the present invention provides an LED display module structure, which has the following beneficial effects:

[0014] 1. When pressing an adjacent LED display module, the magnet of the disassembly mechanism on the reinforcing frame will be subjected to compressive force. At this time, the spring will be compressed and the telescopic rod will retract, causing the pressed LED display module to move inward a certain distance and form a certain height difference with the edge of the problematic module. At this time, the problematic module can be quickly disassembled by manually pressing the disassembly slot. No tools are required, which is convenient and avoids the risk of damage caused by forcibly squeezing the LED display module.

[0015] 2. This LED display module quickly dissipates heat from the PCB panel through a graphene heat-conducting plate, and improves natural heat dissipation efficiency by forming a natural convection airflow channel through a honeycomb heat sink and a heat dissipation metal mesh. When the temperature sensor detects that the temperature on the back of the PCB panel is higher than the set temperature value, the exhaust fan automatically starts to quickly exhaust the heat in the convection airflow channel to the outside through the exhaust pipe. This enables rapid heat dissipation and avoids the problem of excessive heat generated when the LED display has high power, which could cause the LED beads to overheat and affect their lifespan and performance.

Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0023] Reference Figures 1-4 An LED display module structure includes a housing 1, on the outer side of which a PCB panel 2 for mounting LED chips is installed. Inside the housing 1, a reinforcing frame 3 and a heat dissipation mechanism 5 for improving the heat dissipation performance of the PCB panel 2 are installed. At the four corners on one side of the reinforcing frame 3, a disassembly mechanism 4 is installed to facilitate the removal of the entire module from the mounting frame. Using the disassembly mechanism 4, a height difference can be created between two adjacent modules by safe pressing, allowing the problematic module to be removed quickly by hand. At the same time, the heat dissipation mechanism 5 can effectively exhaust and dissipate heat from the PCB panel 2, preventing the LED chips from overheating and improving the lifespan of the LED chips.

[0024] Reference Figures 1-2 The four edges of one side of the reinforcing frame 3 are equipped with connecting sleeves 33 with internal baffles. The back of the PCB panel 2 is equipped with threaded cylinders that match the size and number of the connecting sleeves 33 on the reinforcing frame 3. The threaded cylinders on the PCB panel 2 are inserted into the connecting sleeves 33 from the other side of the reinforcing frame 3 and then tightened with bolts from the other end of the connecting sleeves 33. This allows the PCB panel 2 to be quickly installed on the outer shell 1 after positioning, making the PCB panel 2 easy to disassemble and maintain.

[0025] Reference Figures 1-3The disassembly and assembly mechanism 4 is equipped with a telescopic rod 41. One end of the telescopic rod 41 is fixedly installed at the corner of the reinforcing frame 3, and a magnet 42 is fixedly installed at the other end of the telescopic rod 41. A spring 43 is fitted on the outer ring surface of the telescopic joint of the telescopic rod 41. The two ends of the spring 43 are respectively fixed between the telescopic rod 41 and one side of the magnet 42. One end of the magnet 42 extends 1cm into the inner side of the outer shell 1 in the initial state. When assembling the module, the four magnets 42 are attracted to the metal frame. When the module needs to be disassembled, press the adjacent module at the top, so that the pressed LED display module moves inward a certain distance and forms a certain height difference with the edge of the problematic module. At this time, the problematic module can be quickly disassembled by manually pressing the disassembly slot. No tools are required, which is convenient and avoids the risk of damage caused by forcibly squeezing the LED display module.

[0026] Reference Figure 2 and Figure 4 The reinforcement frame 3 has multiple threaded holes on its four edges. The heat dissipation mechanism 5 includes a honeycomb heat dissipation plate 51 and a heat dissipation metal mesh 54. The honeycomb heat dissipation plate 51 and the heat dissipation metal mesh 54 have through holes that match the size and number of the threaded holes. After the heat dissipation mechanism 5 is placed inside the outer shell 1, it is tightened and fixed by bolts through the through holes on the honeycomb heat dissipation plate 51 and the heat dissipation metal mesh 54 and the threaded holes on the reinforcement frame 3. This structure makes it easy to fix the heat dissipation mechanism 5 inside the outer shell 1 and also makes it easy to disassemble.

[0027] Reference Figure 2 At the center of the length of each protruding edge of the honeycomb heat sink 51 and the heat dissipation metal mesh 54, an arc-shaped groove 52 is provided and fitted onto the outer ring surface of the connecting sleeve 33. Right-angle grooves are provided at the four corners of the honeycomb heat sink 51 and the heat dissipation metal mesh 54, so as to avoid positional interference between the honeycomb heat sink 51 and the heat dissipation metal mesh 54 and the connecting sleeve 33 and the disassembly and assembly mechanism 4 when the honeycomb heat sink 51 and the heat dissipation metal mesh 54 extend into the inner side of the outer shell 1.

[0028] Reference Figure 2 and Figure 4 A heat dissipation mesh 54 is attached to the outer surface of the honeycomb heat sink 51. Four graphene heat-conducting plates 53 are installed on the back of the honeycomb heat sink 51. Four heat dissipation slots 31 matching the size of the graphene heat-conducting plates 53 are provided on the reinforcing frame 3. The graphene heat-conducting plates 53 pass through the heat dissipation slots 31 on the reinforcing frame 3 and are attached to the back of the PCB panel 2. Rectangular slots for exposing power interfaces, signal interfaces, and communication interfaces are provided on the graphene heat-conducting plates 53, the honeycomb heat sink 51, and the heat dissipation mesh 54. The heat from the back of the PCB panel 2 is quickly conducted to the honeycomb heat sink 51 by the graphene heat-conducting plates 53 to form a natural convection airflow channel, and the heat is exhausted to the outside through the heat dissipation mesh 54.

[0029] Reference Figure 2 andFigure 4 An exhaust duct 55 is installed at the center of the outer side of the heat dissipation metal mesh 54. A cooling fan 56 is installed inside the exhaust duct 55. A temperature sensor 32 for monitoring the temperature of the back of the PCB panel 2 is installed at the center of one side of the reinforcement frame 3. When the temperature sensor 32 detects that the temperature value is greater than the set value, the cooling fan 56 automatically shuts down when the temperature value is lower than the set value, thus achieving adaptive active heat dissipation. This ensures that heat is quickly dissipated when the heat generation is large, while reducing the power consumption of the cooling fan 56 under normal temperature conditions.
