Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to an LED display screen. Background Technology

[0002] Currently, large LED display screens are generally composed of multiple LED displays spliced ​​together. Adjacent LED displays are connected in a straight line to place multiple LED displays on the same display plane; adjacent LED displays are also connected at a certain angle to place multiple LED displays on the same display arc surface, thus forming a curved display screen. However, the connection structure of curved display screens at this stage is relatively complex, making splicing extremely inconvenient and unfavorable for the rapid splicing and installation of large-area displays. Some simple connection structures have fixed splicing angles, which cannot meet the splicing and installation requirements of curved screens of different specifications and shapes.

[0024] Please refer to Figure 1 This is an exploded three-dimensional structural diagram of an LED display screen provided by an embodiment of the present utility model. The LED display screen includes a bottom shell 10, a PCB board 20, a stainless steel component 30, and a magnet component 40.

[0025] Please combine Figure 2-4 The PCB board 20 is disposed on one side of the bottom shell 10. Multiple LED beads 210 are arranged in an array on the side of the PCB board 20 facing away from the bottom shell 10. The bottom shell 10 has a first side 110 and a second side 120.

The arc-shaped contact surface can ensure that the stainless steel component 30 and the magnet assembly 40 can rotate relative to each other, so that the two adjacent LED displays can rotate relative to each other, thereby realizing the arc splicing between LED displays.

[0027] In this embodiment of the invention, when assembling two adjacent LED displays, the stainless steel component 30 and the magnet component 40 enable rapid magnetic splicing, improving the splicing and installation efficiency of the LED displays. Furthermore, the arc-shaped contact surfaces of the stainless steel component 30 and the magnet component 40 allow the two LED displays to rotate relative to each other, enabling various arc-shaped splicing of different curvatures between the LED displays and enhancing the user experience of the LED displays.

[0028] Furthermore, in other preferred embodiments of the present invention, the side of the stainless steel component 30 near the magnet component 40 is a connecting cylinder 310, and the side of the magnet component 40 near the stainless steel component 30 is an arc-shaped connecting groove 410 capable of accommodating the connecting cylinder 310, and the connecting cylinder 310 is capable of rotating within the arc-shaped connecting groove 410.

[0029] Specifically, the connecting cylinder 310 is a structure in which the stainless steel component 30 protrudes from the first side 110, and it can be a part of a cylinder; while the magnet component 40 is recessed inward on the second side 120 to form an arc-shaped connecting groove 410 that can accommodate the connecting cylinder 310, thereby allowing the connecting cylinder 310 to rotate within the arc-shaped connecting groove 410, so that the stainless steel component 30 and the magnet component 40 can rotate relative to each other.

[0030] Furthermore, in other preferred embodiments of the present invention, at least two stainless steel components 30 are provided along the length direction of the first side 110, and at least two magnet components 40 are provided along the length direction of the second side 120, and the number of stainless steel components 30 and magnet components 40 are the same and their positions are opposite.

[0031] Specifically, in order to ensure the reliability of splicing between two adjacent LED displays and to avoid gaps, at least two of the stainless steel components 30 are arranged along the length direction of the first side 110, while the same number of magnet components 40 are arranged along the length direction of the second side 120, and the positions of the stainless steel components 30 and the magnet components 40 are corresponding.

[0032] Furthermore, the plurality of stainless steel components 30 and the magnet components 40 are arranged at equal intervals along the length direction of the first side 110 and the second side 120, respectively.

[0033] Furthermore, in other preferred embodiments of the present invention, the magnet assembly 40 includes a magnet fixing base 420 and a magnet 430. The magnet fixing base 420 is fixedly connected to the second side 120. The magnet fixing base 420 is provided with a mounting groove (not shown in the figure) on the side facing the second side 120. The magnet 430 is disposed in the mounting groove. The magnet fixing base 420 is provided with the arc connecting groove 410 on the side away from the second side 120.

[0034] Specifically, the magnet mounting base 420 is fixedly connected to the second side 120 by means of screw connection or other connection methods; the mounting groove is provided on the side of the magnet mounting base 420 facing the second side 120 such that the groove opening faces the second side 120, and the magnet 430 is provided in the mounting groove; at the same time, the arc connecting groove 410 is a groove provided on the side of the magnet mounting base 420 away from the second side 120, and is used to accommodate and connect the connecting cylinder 310 of the adjacent LED display screen.

[0035] Furthermore, in other preferred embodiments of this utility model, the magnet holder 420 is made of plastic or metal that can be penetrated by the magnetic force of the magnet 430.

[0036] This design ensures that the magnetic force of the magnet 430 has sufficient attraction to the stainless steel component 30, thereby effectively improving the reliability of the magnetic connection between the stainless steel component 30 and the magnet component 40.

[0037] Furthermore, in other preferred embodiments of the present invention, the stainless steel component 30 includes a stainless steel fixing base 320 and a stainless steel 330 that can be magnetically connected to the magnet component 40. The stainless steel fixing base 320 is fixedly connected to the first side 110, the stainless steel 330 is connected to the side of the stainless steel fixing base 320 facing away from the first side 110, and the side of the stainless steel 330 facing the magnet component 40 is the connecting cylinder 310.

[0038] Specifically, the stainless steel fixing base 320 is fixedly connected to the first side 110 by means of screws or other connection methods, while the stainless steel 330 is disposed on the side of the stainless steel fixing base 320 facing away from the first side 110, and the end of the stainless steel 330 away from the first side 110 is the connecting cylinder 310, so that the stainless steel 330 (the connecting cylinder 310) can be accommodated in the arc connecting groove 410 and can be rotatably connected to it.

[0039] Furthermore, in other preferred embodiments of the present invention, the stainless steel assembly 30 further includes a spring 340, one end of which is connected to the side of the stainless steel 330 facing the stainless steel fixing seat 320, and the other end of which passes through the stainless steel fixing seat 320 and abuts against the first side 110, so that the stainless steel 330 can extend and retract relative to the stainless steel fixing seat 320.

[0040] Specifically, the spring 340 is disposed between the stainless steel 330 and the first side 110, and its middle part passes through the stainless steel fixing seat 320. The spring 340 has a certain elasticity. Under the magnetic force of the magnet 430, the stainless steel 330 can extend outward and sink into the arc connecting groove 410 and can be rotatably connected with it. The arrangement of the spring 340 can make the connection between the stainless steel assembly 30 and the magnet assembly 40 tighter and improve the reliability of the connection between the two.

[0041] In addition, in other preferred embodiments of the present invention, the stainless steel component 30 further includes a connecting post 350, and the stainless steel 330 is provided with a sliding hole 3301. The connecting post 350 passes through the sliding hole 3301 and its two ends are fixedly connected to the stainless steel fixing base 320, so that the connecting post 350 can slide back and forth in the sliding hole 3301.

[0042] Specifically, the stainless steel 330 has a sliding hole 3301 along its extension direction, and the connecting post 350 passes through the sliding hole 3301 and its two ends are respectively fixedly connected to the stainless steel fixing base 320, so that the stainless steel 330 moves back and forth under the magnetic force of the magnet 430. The sliding hole 3301 and the connecting post 350 can play a guiding role, and at the same time can prevent the stainless steel 330 from separating from the stainless steel fixing base 320, which would damage the connection between the stainless steel assembly 30 and the magnet assembly 40, thereby effectively improving the reliability of splicing between adjacent LED displays.

[0043] Additionally, please combine Figure 5-7 These are schematic diagrams illustrating the structure of an LED display screen splicing method according to embodiments of the present invention, wherein the LED display screen splicing method includes:

[0044] Step 1, as follows Figure 5As shown, multiple LED displays are spliced ​​together in the horizontal direction to form a preset shape. Here, we take splicing multiple LED displays into a ring structure as an example. The figure only shows the splicing between three LED displays as an example. In practice, more LED displays can be spliced ​​together according to the preset shape and the specifications of the LED displays.

[0045] Step 2, following Step 1, connect multiple LED displays sequentially below the top LED display in the vertical direction, ensuring that the spacing between adjacent rows of LED displays gradually increases from top to bottom. Here, the method of connecting multiple LED displays below the top display can be either flat or folded, such as... Figure 6 The LED displays are laid outwards in a flat manner to form a funnel or trumpet-shaped structure that spreads outwards. At this time, the spacing between two adjacent columns of LED displays gradually increases from top to bottom.

[0046] Step 3: Following Step 2 above, gradually raise the top LED display screen so that the spacing between adjacent LED display screens decreases from top to bottom and completes the connection. Here, a lifting device can be used to gradually raise the top LED display screen. At this time, the spacing between adjacent LED display screens will gradually decrease from top to bottom until the LED display screens at the same height are spliced ​​together in the horizontal direction.

[0047] By using this LED display splicing method according to the present invention, multiple LED displays can be quickly spliced ​​into the desired shape, which is suitable for occasions such as stages where rapid splicing is required, and effectively improves the assembly efficiency of LED displays.

[0048] Furthermore, in this embodiment of the invention, two adjacent LED displays in the longitudinal direction are connected by a chain assembly to achieve a folding connection, and two adjacent LED displays in the transverse direction are connected by a stainless steel assembly and a magnet assembly disposed on opposite sides of the LED displays to achieve a magnetic arc connection.

[0049] Specifically, two adjacent LED displays in the same column can be folded together by the chain assembly set on the LED display; while two adjacent LED displays in the same row can be magnetically connected by the stainless steel assembly and magnet assembly set on opposite sides of the LED display in the above embodiment. For details, please refer to the description of the above embodiment, which will not be repeated here.
