Description

Technical Field

[0001] This invention relates to the field of LED display technology, specifically to a modular LED display screen. Background Technology

[0002] LED displays are widely used in commercial advertising, information display, stage performances and other fields due to their high brightness, wide viewing angle and vibrant colors.

[0003] Currently, most LED displays on the market adopt a modular design, which involves splicing together multiple display modules to form a large-size screen.

[0004] However, most existing modular LED displays still have some shortcomings in their structural design and installation methods: First, the connection between modules usually relies on multiple screws for fixing, making the installation and disassembly process cumbersome and inefficient, especially in situations where frequent module replacement or maintenance is required; second, the heat dissipation design of the modules is often not ideal, affecting the lifespan of the LED chips and the display effect; third, the treatment of the joints between modules and the methods for adjusting flatness are complicated, affecting the overall integrity and aesthetics of the display effect; in addition, the protection performance is insufficient, making it difficult to adapt to complex and changing usage environments.

[0005] Therefore, we propose a modular LED display to solve the above-mentioned technical problems. Summary of the Invention

[0006] In view of the problems existing in the prior art, the present invention discloses a modular LED display screen. The technical solution adopted includes a back plate, a front shell, and LED light panels. The back plate and the front shell are fastened together to form a receiving cavity, and a mounting frame for arranging the LED light panels in a rectangular array is installed in the receiving cavity. The mounting frame is embedded and snap-fitted. Support columns for supporting the LED light panels are evenly installed on the inner sidewall of the back plate. Mounting holes are symmetrically opened at the middle of both ends of the front sidewall of the back plate. Positioning grooves are symmetrically opened on the upper and lower sides of the front sidewall of the back plate. Positioning blocks for engaging with the positioning grooves are provided on the rear sidewall of the front shell. A display groove for engaging with a protective plate is opened at the front end of the front shell. A U-shaped pin hole is opened on the rear sidewall of the front shell, and a mounting pin for insertion into the mounting hole is installed in the pin hole. A back clip is provided on the rear sidewall of the back plate. A limiting lever is rotatably installed on the rear sidewall of the back plate, and the rotation center axis of the limiting lever is corresponding to the center axis of the mounting hole.

[0007] As a preferred embodiment of the present invention, it further includes two sets of bracket mounting bases, each bracket mounting base consisting of two bracket mounting plates, which are respectively mounted on one end of the lower side wall of the back plate and one end of the lower side wall of the front plate and are arranged symmetrically.

[0008] As a preferred embodiment of the present invention, the back clip is composed of horizontal and vertical keels, and mounting holes are uniformly formed on the surface of the back clip.

[0009] As a preferred embodiment of the present invention, the keel is made of aluminum alloy profile.

[0010] As a preferred embodiment of the present invention, the faceplate is made of plastic, the front is a frosted light-blocking surface, and the backplate is made of thermally conductive metal.

[0011] As a preferred embodiment of the present invention, the support column is a heat-dissipating silicone column.

[0012] As a preferred embodiment of the present invention, positioning holes are provided at the four corners of the front sidewall of the back panel, and positioning rods that are inserted into the positioning holes are provided at the four corners of the rear sidewall of the panel.

[0013] As a preferred embodiment of the present invention, the outer shell is provided with an outwardly protruding elastic sealing ring around its four edges. When the module is installed in place, the elastic sealing ring is compressed between the outer shell and the mounting frame, which serves to prevent water and dust.

[0014] The beneficial effects of this invention are as follows: Through the cooperation of positioning slots and positioning blocks, mounting holes and mounting pins, and limiting levers, tool-free rapid installation and locking of LED display modules are achieved, significantly improving assembly and maintenance efficiency and reducing labor and time costs. The cooperation of positioning holes and positioning rods, and positioning slots and positioning blocks ensures accurate alignment of each module during splicing, effectively guaranteeing the overall flatness of the display screen and the consistency of display effects. The backplate uses a thermally conductive metal material, combined with heat-dissipating silicone pillars as support pillars, which not only provide support but also rapidly conduct heat generated by the LED light board to the backplate for dissipation, effectively controlling the module's operating temperature and extending its service life. The elastic sealing rings around the front shell are compressed between the front shell and the mounting frame after the module is installed, forming an effective sealing barrier, improving the display screen's dustproof and waterproof rating, and adapting to various environmental applications. The reasonable structural design and easy-to-mass-produce and replace module units, along with the keel structure and standard mounting holes in the back clip, allow this invention to flexibly adapt to various mounting brackets and occasions, making it highly practical.

The back plate 1 and the front shell 2 are fastened together to form a receiving cavity. A mounting frame 3 for arranging the LED light panels 4 in a rectangular array is installed in the receiving cavity. The mounting frame 3 is embedded and snap-fitted. Support columns 5 for supporting the LED light panels 4 are evenly installed on the inner sidewall of the back plate 1. Mounting holes 10 are symmetrically opened at the middle of both ends of the front sidewall of the back plate 1. The upper and lower sides of the front sidewall of the back plate 1 are also provided with mounting holes 10. The panel has symmetrically arranged positioning grooves 6. The rear side wall of the panel is provided with positioning blocks 7 for engaging with the positioning grooves 6. The front end of the faceplate 2 has a display groove 14 for engaging with the protective plate 15. The rear side wall of the panel has a U-shaped pin hole 12, and a mounting pin 13 for insertion into the mounting hole 10 is installed in the pin hole 12. The rear side wall of the back plate 1 is provided with a back clip 17. A limit lever 11 is rotatably mounted on the rear side wall of the back plate 1, and the rotation center axis of the limit lever 11 corresponds to the center axis of the mounting hole 10.

[0020] As a preferred embodiment of the present invention, it further includes two sets of bracket mounting bases 19, each bracket mounting base 19 being composed of two bracket mounting plates 16. The two bracket mounting plates 16 are respectively mounted on one end of the lower side wall of the back plate 1 and one end of the lower side wall of the front panel and are arranged symmetrically.

[0021] As a preferred embodiment of the present invention, the back clip 17 is composed of horizontal and vertical keels, and mounting holes 18 are uniformly opened on the surface of the back clip 17.

[0022] As a preferred embodiment of the present invention, the keel is made of aluminum alloy profile.

[0023] As a preferred embodiment of the present invention, the faceplate 2 is made of plastic, the front is a frosted light-blocking surface, and the backplate 1 is made of thermally conductive metal.

[0024] As a preferred embodiment of the present invention, the support column 5 is a heat-dissipating silicone column.

[0025] As a preferred embodiment of the present invention, positioning holes 8 are provided at the four corners of the front side wall of the back plate 1, and positioning rods 9 are provided at the four corners of the rear side wall of the panel to be inserted into the positioning holes 8.

[0026] As a preferred technical solution of the present invention, the outer shell 2 is provided with an outwardly protruding elastic sealing ring around its four edges. When the module is installed in place, the elastic sealing ring is compressed between the outer shell 2 and the mounting frame 3, which serves to prevent water and dust.

[0027] Working principle of the invention: First, the LED light board 4 is pre-arranged and fixed to the inside of the back plate 1 by the mounting frame 3 in an embedded snap-fit ​​manner. The back of the LED light board 4 is supported and buffered by evenly distributed support columns 5. At the same time, the support columns 5 made of heat dissipation silicone can conduct the heat generated by the light board during operation to the metal back plate 1, accelerating heat dissipation. Subsequently, the front shell 2 and the back plate 1 are aligned, and the initial positioning and engagement are achieved through the cooperation of the positioning block 7 and the positioning groove 6, and the positioning rod 9 and the positioning hole 8, to ensure that the relative positions of the front shell and the back plate are accurate. Next, insert the mounting pin 13 into the U-shaped pin hole 12 on the rear side of the faceplate 2, so that it passes through the pin hole 12 and enters the mounting hole 10 on the backplate 1. At this time, rotate the limiting lever 11 to lock it into the end of the mounting pin 13, preventing the pin from coming loose during vibration or long-term use, thereby achieving a firm lock between the back plate 1 and the front shell 2, forming a sealed cavity that protects the internal LED light panel 4. A protective plate 15 (such as a transparent PC board or glass) can be snapped into the display slot 14 at the front of the faceplate 2 to further protect the LED light surface. The entire module can be connected to an external bracket or mounting surface through the back clip 17 on the back side of the back plate 1. The back clip 17 is made of aluminum alloy keel, which is lightweight and strong. The mounting holes 18 on it facilitate flexible installation. When multiple modules are spliced ​​together, the elastic sealing rings around the modules are compressed between the faceplate 2 and the mounting frame 3 or adjacent modules to form a seal, which can prevent dust and water.
