[0003] After searching, the existing patent number CN118159001B discloses an outdoor LED display box structure. A real-time temperature monitoring device is installed in the middle of the front end of the fixed plate. The real-time temperature monitoring device is driven by two sets of motors, and multiple sets of temperature sensors are built into the rotating shaft. Under the drive, the rear end of the display assembly can be accurately detected over a large range, which can facilitate the positioning of abnormal hot spots on the display screen and facilitate manual maintenance and inspection; and heat exhaust devices are installed at the upper and lower positions of the front end surface of the fixed plate. The two sets of heat exhaust devices are arranged relative to each other. Under the drive of the internal motor, the toggle mechanism cooperates with the external blowing equipment to increase the air flow rate inside the box, which is convenient for rapid heat extraction and efficient heat dissipation.

[0004] Existing LED display screens still have the following defects: (1) The heat dissipation structure is complex and requires the use of energy-consuming devices such as independent fans for heat dissipation, which not only increases costs and conflicts with the protective structure, but is also not conducive to modular rapid disassembly and maintenance; (2) Most of them adopt a modular stacking design, and each functional component such as protection, heat dissipation and assembly exists independently, resulting in structural redundancy, high cost and poor compatibility. Summary of the Invention

[0005] The purpose of the present invention is to provide an LED display screen module, aiming to solve the problems existing in the existing LED display screens.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an LED display screen module, comprising an LED light board, an inner sealed shell, and an outer heat dissipation shell, wherein the LED light board is fixedly embedded in the inner sealed shell, comprising: A limiting protrusion fixedly arranged on the back of the LED light board, with a limiting hole provided on the surface of the limiting protrusion, and the limiting protrusion passing through the inner sealing shell; A self-locking clip heat dissipation module, comprising a base, an elastic clip and a self-locking structure, wherein the base is fixedly arranged on the surface of the inner sealing shell, the elastic clip is clamped at the end of the base, and the self-locking structure comprises a pressure-bearing member, an arrow plate, an inclined guide rail, an L-shaped pin and a spring, wherein the pressure-bearing member is fixedly connected to the arrow plate, the arrow plate is slidably connected to the base, an inclined guide rail is provided on the surface of the arrow plate, the L-shaped pin is slidably connected to the inclined guide rail, the spring is connected between the pressure-bearing member and the base, and the L-shaped pin is inserted into the limiting hole; A card slot is provided on the inner side of the outer heat dissipation shell, the limiting protrusion, the base and the elastic card are all in contact with the card slot, a pressure rod is fixedly provided in the card slot, and the pressure rod is in contact with the surface of the pressure bearing member.

[0007] As a further solution of the present invention, a locking end is provided at the end of the base, the elastic card is clamped at the locking end, the base surface is provided with an insertion interface and a linear guide rail, the pressure rod can pass through the insertion interface, and the L-shaped pin rod is slidably connected in the linear guide rail.

[0008] As a further solution of the present invention, the surfaces of the limiting protrusion, the self-locking buckle heat dissipation module and the pressure rod are all coated with thermal conductive paint.

[0009] As a further solution of the present invention, an annular glue groove and a first heat dissipation fin are respectively provided on the inner side and the outer side of the inner sealing shell.

[0010] As a further solution of the present invention, second heat dissipation fins are provided on the surface of the outer heat dissipation shell.

[0011] As a further solution of the present invention, a heat-conducting medium interlayer is filled between the inner sealing shell and the outer heat dissipation shell.

[0012] As a further solution of the present invention, the outer heat dissipation shell and the inner sealing shell are respectively fixedly provided with a limiting insert and a limiting socket, and the limiting insert is plugged and connected in the limiting socket.

[0013] As a further solution of the present invention, the interior of the base is a hollow structure, and the interior of the base is connected to the card slot through an insertion interface.

[0016] The beneficial effects of the present invention are as follows: (1) The present application utilizes a structural design in which a limiting protrusion, a self-locking clip heat dissipation module, a card slot and a pressure rod cooperate with each other. While the inner sealing shell and the outer heat dissipation shell are fixedly connected by the elastic card and the slot, the pressure rod is used to drive the L-shaped pin rod to insert into the limiting holes on both sides of the limiting protrusion. Conversely, the L-shaped pin rod automatically disengages from the limiting protrusion, thereby solving the problem that the traditional clip structure cannot fix the LED light board at the same time, and has the characteristics of easy disassembly and easy maintenance.

[0017] (2) Since the interior of the base is connected to the card slot through the plug-in interface, the limiting protrusion, the base and the elastic card are all in contact with the card slot. Therefore, the heat can be transferred to the card slot or the outer heat dissipation shell through the limiting protrusion and the self-locking buckle heat dissipation module, and the first heat dissipation fin and the second heat dissipation fin are used for rapid heat dissipation by natural convection, which solves the problem that the transfer structure in the traditional LED display module cannot assist in heat dissipation.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0031] See also Figures 1 to 10 In one embodiment of the present invention, an LED display screen module includes an LED light board 1, an inner sealed shell 2, and an outer heat dissipation shell 4. The LED light board 1 is fixedly embedded in the inner sealed shell 2, and includes: A limiting protrusion 11 is fixedly arranged on the back of the LED light board 1, a limiting hole is provided on the surface of the limiting protrusion 11, and the limiting protrusion 11 passes through the inner sealing shell 2; The self-locking clip heat dissipation module 3 includes a base 31, an elastic clip 32 and a self-locking structure 33.

The self-locking structure 33 includes a pressure-bearing member 331, an arrow plate 332, an inclined guide rail 3321, an L-shaped pin 333 and a spring 334. The pressure-bearing member 331 is fixedly connected to the arrow plate 332, and the arrow plate 332 is slidably connected to the base 31. The surface of the arrow plate 332 is provided with an inclined guide rail 3321. The L-shaped pin 333 is slidably connected to the inclined guide rail 3321. The spring 334 is connected between the pressure-bearing member 331 and the base 31, and the L-shaped pin 333 is inserted into the limiting hole. A card slot 42 is provided on the inner side of the outer heat dissipation shell 4 , and the limiting protrusion 11 , the base 31 and the elastic card 32 are all in contact with the card slot 42 . A pressure rod 421 is fixedly provided in the card slot 42 , and the pressure rod 421 is in contact with the surface of the pressure member 331 .

[0032] See also Figures 4 to 6Furthermore, a locking end 311 is provided at the end of the base 31, and the elastic card 32 is clamped at the locking end 311. The surface of the base 31 is provided with an insertion port 312 and a linear guide rail 313. The pressure rod 421 can pass through the insertion port 312, and the L-shaped pin rod 333 is slidably connected in the linear guide rail 313.

[0033] Furthermore, the surfaces of the limiting protrusion 11, the self-locking buckle heat dissipation module 3 and the pressure rod 421 are coated with thermal conductive paint, and the thermal conductive paint contains metal powder (such as aluminum, copper, etc.) as thermal conductive filler to provide high thermal conductivity.

[0034] See also Figure 1 、 Figure 2 and Figure 7 Furthermore, an annular glue groove 24 and a first heat dissipation fin 21 are respectively provided on the inner and outer sides of the inner sealing shell 2, and a second heat dissipation fin 41 is provided on the surface of the outer heat dissipation shell 4. The first heat dissipation fin 21 and the second heat dissipation fin 41 utilize natural convection to assist heat dissipation.

[0035] See also Figure 6 and Figure 10 Furthermore, the interior of the base 31 is a hollow structure, and the interior of the base 31 is connected to the card slot 42 through the plug interface 312. A heat-conducting medium interlayer 23 is filled between the inner sealed shell 2 and the outer heat dissipation shell 4. The heat generated by the LED lamp board 1 when working can be directly transferred to the inner sealed shell 2 and the outer heat dissipation shell 4 through the heat-conducting medium interlayer 23. The hollow structure of the base 31 plays a role in air circulation, which can pass the heat generated by the LED lamp board 1 when working.

[0036] Furthermore, the base material of the pressure-bearing part 331 is metal, the pressure-bearing part 331 is a copper sheet, a neodymium iron boron magnet is embedded on the surface of the pressure-bearing part 331, the pressure rod 421 is made of metal, the pressure rod 421 is an iron rod, and the magnetic attraction between the neodymium iron boron magnet and the pressure rod 421 serves to assist in quickly and accurately passing the pressure rod 421 through the plug-in interface 312.

[0037] In an embodiment of the present invention, the inner sealing shell 2 and the outer heat dissipation shell 4 are both made of high thermal conductivity aluminum alloy. The inner sealing shell 2 is a sealed cavity. When the LED light board 1 is assembled with the inner sealing shell 2, the annular silicone is first filled in the annular rubber groove 24. When the LED light board 1 is embedded in the inner sealing shell 2, the limiting protrusion 11 passes through the through hole reserved on the surface of the inner sealing shell 2, and the airtight packaging of the LED light board 1 and the inner sealing shell 2 is achieved by a hot pressing process. The outer heat dissipation shell 4 and the inner sealing shell 2 are respectively fixed with a limiting insert 43 and a limiting socket 22. The limiting insert 43 is connected to the limiting socket 22 by being plugged in to enhance the limiting effect. The two L-shaped pins 333 and the pressure rod 421 are symmetrical about the center of the base 31, and two groups of limiting holes are symmetrically arranged on the top of the limiting protrusion 11.

[0038] Working principle: Assembly link: First, fill the annular rubber groove 24 with annular silicone, and at the same time, embed the LED light board 1 into the inner sealing shell 2. The limiting protrusion 11 passes through the through hole reserved on the surface of the inner sealing shell 2, and uses the hot pressing process to achieve the airtight packaging of the LED light board 1 and the inner sealing shell 2. Then, assemble the inner sealing shell 2 with the self-locking buckle heat dissipation module 3 and the outer heat dissipation shell 4. In the process of the self-locking buckle heat dissipation module 3 entering the slot 42, the pressure rod 421 enters the plug interface 312 to press the pressure-bearing part 331. In the process of the pressed pressure-bearing part 331 and the arrow plate 332 moving, The inclined guide rail 3321 can be used to drive the two L-shaped pins 333 to move backward along the linear guide rail 313. When the elastic card 32 of the locking end 311 of the base 31 is engaged in the card slot 42, the two L-shaped pins 333 are respectively inserted into the limiting holes on both sides of the limiting protrusion 11, which can simultaneously achieve a fixed connection between the outer heat dissipation shell 4 and the inner sealing shell 2, and between the inner sealing shell 2 and the LED light board 1. When the elastic card 32 is removed or disengaged from the card slot 42, the elastic force of the spring 334 drives the L-shaped pins 333 to disengage from the limiting protrusion 11 by moving the arrow plate 332 in the opposite direction, which has the characteristic of easy disassembly and assembly. Moisture-proof heat dissipation principle: On the one hand, the heat generated by the LED lamp board 1 when working can be directly transferred to the inner sealing shell 2 and the outer heat dissipation shell 4 through the heat-conducting medium interlayer 23. On the other hand, since the inside of the base 31 is connected with the card slot 42 through the plug interface 312, the limiting protrusion 11, the base 31 and the elastic card 32 are all in contact with the card slot 42, so it can be transferred to the card slot 42 or the outer heat dissipation shell 4 through the limiting protrusion 11 and the self-locking buckle heat dissipation module 3. The first heat dissipation fins 21 and the second heat dissipation fins 41 use natural convection to dissipate heat, which solves the problem that the transfer structure in the traditional LED display module cannot assist in heat dissipation, and has the characteristics of taking into account both sealed heat dissipation and easy disassembly and assembly.

[0039] To sum up, the present application utilizes a structural design in which the limiting protrusion 11, the self-locking clip heat dissipation module 3, the card slot 42 and the pressure rod 421 cooperate with each other. While the inner sealing shell 2 and the outer heat dissipation shell 4 are fixedly connected by the elastic card 32 and the slot, the pressure rod 421 is used to drive the L-shaped pin 333 to be inserted into the limiting holes on both sides of the limiting protrusion 11. Conversely, the L-shaped pin 333 automatically disengages from the limiting protrusion 11, solving the problem that the traditional clip structure cannot fix the LED light board 1 at the same time, and has the characteristics of easy disassembly and maintenance.
