[0017] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1 like Figures 1-8 As shown, the present invention discloses a multi-dimensional, splicable LED stereoscopic display screen and its splicing method, comprising a stereoscopic module, which is composed of six display modules. The display modules include a magnet 11, a magnetic sheet 12, a conductive spring 13, a conductive column 14, an LED light board 15, a fixed portion 21, and a printed circuit board (PCB). The LED light board 15 is provided on the outside of the PCB and comprises a toothed inner frame 111, a connecting block 112, a connecting plate 113, and a toothed outer frame 114. One side of the connecting plate 113 connects to the inner side of the magnetic sheet 12, and the other side of the connecting block 112 connects to the inner side of the magnet 11. The connecting block 112 improves the stability of the magnet 11.

[0021] The toothed outer frame 114 is equipped with protrusions and grooves. The complementary design of the protrusions and grooves enables precise alignment between display modules, reducing splicing errors and ensuring a seamless connection. One side of the toothed inner frame 111 is connected to the fixed portion 21, which provides mechanical stability through the toothed inner frame 111 to prevent deformation after splicing. The other side of the toothed inner frame 111 is connected to the toothed outer frame 114 via a connecting block 112. The inner side of the toothed outer frame 114 is embedded with magnets 11 and conductive posts 14. The outer groove of the toothed outer frame 114 matches the magnetic attraction sheet 12 and conductive spring 13. The conductive spring 13 is located outside the groove and contacts the raised conductive post 14 of the adjacent display module to achieve circuit conduction. The magnetic attraction sheet 12 enhances the magnetic attraction force, ensuring that the groove side and the raised side are tightly attracted during splicing. The inner side of the raised side is equipped with magnets 11 and conductive posts 14. The magnets 11 and the magnetic attraction sheet 12 on the groove side cooperate to provide the magnetic attraction force required for splicing. Conductive posts 14 contact the conductive springs 13 on the sides of the grooves, forming a circuit path. There are four conductive springs 13 and four conductive posts 14, distributed around the module, supporting power transmission during multi-directional splicing and avoiding single points of failure.

[0022] There are sixteen magnetic attracting plates 12 and sixteen magnets 11, with four magnetic attracting plates 12 and magnets 11 on each side (four sides total). This ensures sufficient attraction on all sides of the module, enhancing joint strength. Each side of the toothed outer frame 114 features a conductive spring 13, and each side of the toothed outer frame 114 features a conductive post 14. Each side of the toothed outer frame 114 features four magnetic attracting plates 12, and each side of the toothed outer frame 114 features four magnets 11. The conductive posts 14 correspond one-to-one with the conductive springs 13, ensuring a single point of contact during assembly, reducing assembly complexity. The four magnets 11 correspond one-to-one with the four magnetic attracting plates 12, forming a symmetrical magnetic field.

[0023] The bottom of the conductive spring 13 is welded on the PCB board, and the bottom of the conductive column 14 is welded on the PCB board. Welding ensures that the conductive spring 13 fits tightly with the PCB board to avoid poor contact due to vibration or external force during splicing. Welding allows the conductive spring 13 to be directly connected to the circuit inside the PCB board, providing a stable path for current transmission between adjacent display modules; the conductive column 14 serves as a circuit contact during splicing, and is welded on the PCB board so that it simultaneously connects the internal circuit and the conductive spring 13 of the adjacent display module, achieving cross-module circuit conduction. Welding fixation prevents the conductive column 14 from loosening or shifting during multiple splicing / disassembly; a PCB board circuit is provided on the PCB board and close to the conductive spring 13 and the conductive column 14. The circuit is close to the conductive spring and the conductive column, reducing the current transmission distance, resistance and signal loss; the PCB board circuit includes a negative pole of the PCB circuit and a positive pole of the PCB circuit.

[0024] The fixed portion 21 includes a support body 211, a first support plate 212, and a second support plate 213. The support body 211 is connected to the toothed inner frame 111 via the first support plate 212. The first support plate 212 is cross-shaped, and the cross-shaped structure provides symmetrical support to adapt to external forces from multiple directions. There are four first support plates 212, and the four first support plates 212 face different directions and are 90 degrees apart, enhancing overall rigidity. A second support plate 213 is provided between two adjacent first support plates 212. The support body 211, first support plate 212, and second support plate 213 are integrally formed by injection molding, improving reliability over long-term use.

[0025] One side of the connecting plate 113 is fixed to the inner area of the magnetic attraction plate 12, while the opposite side of the connecting block 112 is connected to the inner area of the magnet 11. There are sixteen connecting blocks 112 and sixteen connecting plates 113. Each display module is equipped with four connecting blocks / plates on each of the four sides (four sides in total), ensuring even distribution of the magnets and magnetic attraction plates. Each magnet 11 corresponds to one connecting plate 113. Each magnetic attraction plate 12 is secured to each connecting block 112, and the magnet 11 and magnetic attraction plate 12 are secured to each other via the connecting plates 113, ensuring accurate magnetic alignment during assembly. The connecting blocks 112, connecting plates 113, toothed inner frame 111, and toothed outer frame 114 are integrally formed by injection molding.

[0026] The six display modules include a display module bottom 1, a display module left side 2, a display module right side 3, a display module top 4, a display module rear side 5, and a display module front side 6. The display module bottom 1, the display module left side 2, the display module right side 3, the display module top 4, the display module rear side 5, and the display module front side 6 have the same structure.

[0027] Step S1: Assemble the display module bottom 1, display module left 2, display module right 3, display module top 4, display module front 6, and display module rear 5. Complete the independent assembly of a single display module to ensure that each display module functions properly.

[0028] Step S2, the bottom portion 1 of the display module is connected to the left portion 2 of the display module; The left side of the display module 2 is gradually brought closer to the left side of the bottom of the display module 1. The corresponding arrangement of the protrusions and grooves causes the magnet 11 and magnetic attraction sheet 12 on the side of the left side of the display module 2 near the bottom of the display module 1 to attract the magnet 11 and magnetic attraction sheet 12 on the left side of the bottom of the display module 1, and the left side of the display module 2 and the bottom of the display module 1 are tightly attracted to each other.

[0029] The conductive spring piece 13 and the conductive column 14 on the left side 2 of the display module close to the bottom 1 of the display module are in contact with the conductive spring piece 13 and the conductive column 14 on the left side of the display module bottom 1, and the circuit between the left side 2 of the display module and the bottom 1 of the display module is conductive.

[0030] The magnet 11 and the magnetic attraction sheet 12 are attracted to each other to achieve physical fixation, and the protrusions and grooves ensure the alignment accuracy. The conductive spring 13 contacts the conductive column 14 to activate the circuit path between adjacent display modules.

[0032] The display module rear side 5 is gradually brought closer to the display module bottom 1 and the display module left side 2. The corresponding arrangement of the protrusions and grooves causes the magnets 11 and magnetic attraction pieces 12 on both sides of the display module rear side 5 near the display module bottom 1 and the display module left side 2 to attract each other, and the display module rear side 5 is tightly attracted to the display module bottom 1 and the display module left side 2.

[0033] The rear side 5 of the display module is close to the conductive springs 13 and the conductive posts 14 on both sides of the bottom 1 of the display module and the left side 2 of the display module, and is in contact with the conductive springs 13 and the conductive posts 14 on the rear side of the bottom 1 of the display module and the rear side of the left side 2 of the display module, so that the circuit is conductive between the rear side 5 of the display module and the bottom 1 of the display module and the left side 2 of the display module.

[0034] Step S4: The right side 3 of the display module is connected to the rear side 5 of the display module and the bottom side 1 of the display module at the same time.

[0035] The right side 3 of the display module is gradually brought closer to the bottom 1 of the display module and the rear side 5 of the display module. By correspondingly setting the protrusions and grooves, the magnets 11 and magnetic attraction pieces 12 on both sides of the right side 3 of the display module near the bottom 1 of the display module and the rear side 5 of the display module attract each other, and the right side 3 of the display module is tightly attracted to the bottom 1 of the display module and the rear side 5 of the display module.

[0036] The right side 3 of the display module is close to the conductive springs 13 and the conductive posts 14 on both sides of the bottom 1 of the display module and the rear side 5 of the display module, and contacts the conductive springs 13 and the conductive posts 14 on the right side of the bottom 1 of the display module and the right side of the rear side 5 of the display module, so that the circuit between the right side 3 of the display module and the bottom 1 of the display module and the rear side 5 of the display module is conductive; Step S5 , the display module front side 6 is connected to the display module left side 2 , the display module right side 3 , and the display module bottom 1 at the same time.

[0037] The front side 6 of the display module is gradually brought closer to the bottom 1, left side 2, and right side 3 of the display module. The corresponding protrusions and grooves are arranged. The magnets 11 and magnetic attraction plates 12 on the three sides of the front side 6 of the display module near the bottom 1, left side 2, and right side 3 of the display module attract each other, tightly attracting the front side 6 of the display module and the bottom 1, left side 2, and right side 3 of the display module. The conductive springs 13 and conductive posts 14 on the three sides of the front side 6 of the display module near the bottom 1, left side 2, and right side 3 of the display module come into contact with the conductive springs 13 and conductive posts 14 on the front side of the bottom 1, left side 2, and right side 3 of the display module, ensuring electrical continuity between the front side 6 of the display module and the bottom 1, left side 2, and right side 3 of the display module.

[0038] Step S6 , the display module top 4 is simultaneously connected to the display module left 2 , the display module right 3 , the display module front 6 and the display module rear 5 to form a three-dimensional module.

[0039] The top 4 of the display module is gradually brought closer to the front 6, left 2, right 3, and rear 5 of the display module. The corresponding protrusions and grooves are arranged. The magnets 11 and magnetic attraction sheet 12 on the four sides of the top 4 of the display module near the front 6, left 2, right 3, and rear 5 of the display module attract each other with the magnets 11 and magnetic attraction sheet 12 on the upper sides of the front 6, left 2, right 3, and rear 5 of the display module. The top 4 of the display module is tightly attracted to the front 6, left 2, right 3, and rear 5 of the display module.

[0040] The conductive springs 13 and conductive posts 14 on the top 4 of the display module, near the front 6, left 2, right 3, and rear 5 of the display module, attract each other. The top 4 of the display module is in contact with the front 6, left 2, right 3, and rear 5 of the display module. Electrical continuity is achieved between the top 4 of the display module, the front 6, left 2, right 3, and rear 5 of the display module.
