[0033] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is referenced.

[0034] Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0035] The utility model provides an LED display module for fixing a light board module, which does not require bolts to fix, thereby improving the convenience of disassembling and assembling the light board module; and avoids the situation where the light board module is easy to fall off when fixed with magnets, thereby improving the stability of the light board module installation, and is suitable for the installation and use of outdoor LED display screens.

[0036] Example 1:

[0037] like Figure 1 and Figure 2 As shown, the LED display module includes a first base plate 1 and multiple first light boards 2. The multiple first light boards 2 are arranged in an array on the first base plate 1. In this embodiment, six first light boards 2 are preferably installed in an array on the same first base plate 1. The first base plate 1 is made of aluminum. The first surface of the first base plate 1 and the first surface of the first light board 2 are opposite each other. The first surface of the first base plate 1 is provided with a plurality of first spring buckles 11, and the first surface of the first light board 2 is provided with a plurality of undercuts 21. The undercuts 21 on any one of the first light boards 2 correspond to the plurality of first spring buckles 11 in a one-to-one manner and can be detachably connected. When installing the first light board 2, it is only necessary to press and snap the undercuts 21 on the first light board 2 into contact with the spring clips on the first base plate 1 one by one, without the need for positioning or fixing with the help of tools, thereby improving the convenience of installing the first light board 2; and, after the undercuts 21 are snapped and fixed with the first spring clips 11, a force perpendicular to the first light board 2 and in the opposite direction to that when the first light board 2 is installed is applied to the first light board 2 to remove the first light board 2, thereby avoiding the lateral movement of the first light board 2 causing deformation of the LED display screen and falling off of the first light board 2, making disassembly and assembly convenient and improving installation stability.

[0038] Furthermore, if Figure 2 As shown, the first spring clip 11 includes a cylindrical base 12 and a plurality of elastic claws 13 disposed on the base 12. The first ends of the plurality of elastic claws 13 are connected to the first end of the base 12, and the second ends of the plurality of elastic claws 13 converge toward the center to form a circular hole. A receiving cavity is formed between the plurality of elastic claws 13. The undercut 21 squeezes the ends of the plurality of elastic claws 13 to deform and expand them, and then passes through the circular hole between the plurality of elastic claws 13. The undercut 21 is engaged in the receiving cavity between the plurality of elastic claws 13. When removing the first light panel 2, it is necessary to apply axial force to the undercut 21. The undercut 21 squeezes the plurality of elastic claws 13 again to deform and expand them before they can be pulled out of the receiving cavity, thereby preventing the first light panel 2 from falling off.

[0039] like Figure 2 As shown, the first base plate 1 has multiple through-holes, and the second end of the base 12 has a threaded hole. The base 12 is pre-secured to the first side of the first base plate 1 using bolts threaded through the through-holes. The undercut 21 is pre-welded to the first side of the first light panel 2 using a surface mount mounting method. On-site installation requires only that the undercut 21 be connected to the first spring 11.

[0040] Preferably, if Figure 1As shown, a plurality of mutually parallel first support bars 14 are provided on the first base plate 1. The cross-section of the first support bar 14 is T-shaped. The first surface of any first light board 2 is in contact with at least two first support bars 14. The first light board 2 is supported by the first support bars 14 to ensure that the second surfaces of the plurality of first light boards 2 are located in the same plane.

[0041] Example 2:

[0042] like Figure 1 and Figure 2 As shown, the LED display module includes a second base plate 3 and multiple light board modules. The light board module includes a second light board 5 and a bottom shell 4 that are interconnected. The second light board 5 is fixedly connected to the bottom shell 4 in advance when the light board module leaves the factory. Multiple bottom shells 4 are arranged in an array. The bottom shell 4 and the second base plate 3 are detachably connected by multiple pairs of second spring clips 40. The second spring clips 40 are fixedly connected to the second base plate 3 by plastic deformation. When installing the second light board 5, it is only necessary to match the light board module to the second base plate 3 and press the second light board 5 with a force perpendicular to the light board module. The second spring clips 40 are plastically deformed and then snapped onto the second base plate 3. No tools are required to fix it, which improves the convenience of light board module installation. When disassembling, the second spring clips 40 are forced to deform again by using a force in the opposite direction, or by pressing the second spring clips 40 to force them to deform, so as to separate the second spring clips 40 from the second base plate 3. This facilitates disassembly and assembly, prevents the light board module from falling off, and improves installation stability.

[0043] like Figure 3 As shown, the bottom shell 4 includes a frame 41 and a plurality of longitudinal beams 42 and transverse beams 43 disposed within the frame 41 and interconnected. The bottom shell 4 is preferably made of plastic, and the longitudinal beams 42 and transverse beams 43 improve the strength of the bottom shell 4. A second spring catch 40 is disposed on a set of opposing inner side surfaces of the frame 41. The second spring catches 40 are opposed to each other in pairs. A hook 44 is disposed on the bottom shell 4 at a position corresponding to each second spring catch 40. When the bottom shell 4 is pressed, the second spring catch 40 is squeezed by the hook 44 and plastically deformed. After the second spring catch 40 passes over the hook 44, it returns to its original position and is fixedly engaged with the hook 44. Specifically, the second spring catch 40 includes a U-shaped plate 401 and a limiting protrusion 402 disposed on the U-shaped plate 401. Both ends of the U-shaped plate 401 are connected to the inner side surface of the frame 41. When the bottom shell 4 is pressed, the U-shaped plate 401 undergoes plastic deformation, and the limiting protrusion 402 is displaced as the U-shaped plate 401 is deformed. After the limiting protrusion 402 passes over the hook 44, the U-shaped plate 401 is reset, and the limiting protrusion 402 abuts against the hook 44, and the second spring buckle 40 is engaged with the hook 44. The reverse operation can realize the separation of the second spring buckle 40 and the hook 44.

[0044] like Figure 3 As shown, reinforcing ribs are provided at the connection between the longitudinal beam 42 and the transverse beam 43 to further improve the strength of the bottom shell 4 .

[0045] like Figure 1 As shown, the bottom plate is provided with multiple mutually parallel second support bars 45. The second support bars 45 have a rectangular cross-section and a convex top surface. Multiple hooks 44 are spaced along the length of the second support bars 45 on the stepped surfaces on both sides. Multiple second snap hooks 40 corresponding to the positions of the hooks 44 are provided on the inner side surfaces of a set of opposing sides of the bottom shell 4. The multiple hooks 44 are detachably connected to the multiple second snap hooks 40 in a one-to-one correspondence. The frame 41 of any bottom shell 4 abuts against at least two second support bars 45 to support the bottom shell 4 and ensure that the upper surface of the second light panel 5 lies in the same plane.

[0046] like Figure 1 As shown, a plurality of mounting holes 46 are provided on the bottom plate, and the connecting wires or interfaces of the light board module are set in the mounting holes 46, and the mounting holes 46 are used for threading wires or installing interfaces.
