The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] Please refer to Figure 1 , is a schematic diagram of a three-dimensional structure explosion of an LED light board provided by an embodiment of the present invention, wherein the LED light board includes a frame bracket 10, a magnet 20 and a circuit board 30

[0028] The frame bracket 10 has a receiving groove 110;

[0029] The magnet 20 is disposed in the receiving groove 110;

[0030] The circuit board 30 is detachably connected to the frame bracket 10 and covers the receiving groove 110;

[0031] LED lamp beads (not shown in the figure) are arranged in an array on the side of the circuit board 30 away from the frame bracket 10;

[0032] Among them, when two LED light panels are spliced ​​together, the directions of the magnetic flux lines of the magnets 20 on two adjacent frame brackets 10 are perpendicular to the frame brackets 10 where they are located, and the magnets 20 on two adjacent frame brackets 10 are connected by magnetic attraction.

[0033] Specifically, its combination Figure 2-5. The frame bracket 10 is generally a quadrilateral frame, and a rectangular or square frame is particularly preferred. The frame structure has strong splicing properties and is easy to operate. The material of the frame bracket 10 includes but is not limited to plastic material. The frame bracket 10 is provided with the receiving groove 110. Here, the receiving groove 110 can be a groove in which the frame bracket 10 as a whole sinks and bulges to the other side, or it can be a structure in which the surface of the frame bracket 10 is concave downward and the other side is flush with other positions. The receiving groove 110 is used to accommodate the magnet 20; the circuit board 30 is provided above the magnet 20, and the circuit board 30 is detachably connected to the frame bracket 30. The specific connection method includes but is not limited to screw connection. When the circuit board 30 is connected to the frame bracket 10, the circuit board 30 just covers the receiving groove 110 and the magnet 20. A plurality of LED lamp beads are arranged in an array on the circuit board 3 0 is away from the side of the frame bracket 10, and then the display surface is formed on the side of the circuit board 30 away from the frame bracket 10. In other preferred embodiments of the present invention, the LED light board is a transparent light board. At this time, a plurality of through holes are provided on the circuit board 30, and a plurality of LED lamp beads are distributed on the circuit board 30 between the plurality of through holes; when the two LED light boards of the embodiment of the present invention are spliced, the direction of the magnetic flux lines of the magnets 20 on the two adjacent frame brackets 10 is perpendicular to the frame bracket 10 where they are located, that is, the line connecting the N pole and the S pole of the magnet 20 is perpendicular to the length direction of the frame bracket 10 where they are located. Such a design can make the magnets 20 on the two adjacent frame brackets 10 connected by magnetic attraction when the two LED light boards are spliced, so that the two adjacent LED light boards can be quickly aligned by the magnets, thereby realizing rapid splicing of the LED light boards and improving the operating efficiency of the LED display screen.

[0034] Furthermore, the receiving groove 110 is located on one side of the outer edge of the frame bracket 10 without a groove wall, so that the magnet 20 is exposed outward.

[0035] Specifically, the receiving groove 110 is arranged along the outer edge of the frame bracket 10, and the side wall of the receiving groove 110 located on the outside is removed, that is, the outside of the magnet 20 is exposed and is not wrapped by the groove wall of the receiving groove 110. Such a design can enhance the suction force when the two magnets 20 are magnetically attracted to each other, so that the connection between the two adjacent LED light panels is more secure.

[0036] Furthermore, in other preferred embodiments of the present invention, a plurality of the accommodating grooves 110 are provided at intervals along a circle of the frame bracket 10 , and each of the accommodating grooves 110 is provided with a magnet 20 .

[0037] Specifically, the plurality of receiving grooves 110 are spaced apart along a circle of the frame bracket 10. In a preferred embodiment, the plurality of receiving grooves 110 are equally spaced along a circle of the frame bracket 10, and a magnet 20 is provided in each of the receiving grooves 110. Such a design can ensure that when the LED light panels are spliced, there is a relatively uniform magnetic attraction force at each location between two adjacent LED light boards, thereby ensuring the reliability and flatness of the splicing of the LED light panels.

[0038] Furthermore, in other preferred embodiments of the present invention, a light-shielding adhesive strip 40 is further included, which is provided between the frame bracket 10 and the circuit board 30 and shields the receiving groove 110 .

[0039] Specifically, the light-shielding strip 40 is similar in shape to the frame bracket 10, is connected to the side of the frame bracket 10 facing the circuit board 30, and is sandwiched between the frame bracket 10 and the circuit board 30. The light-shielding strip 40 shields the receiving groove 110 and the magnet 20; here, the light-shielding strip 40 is used to block the lateral light emission of the LED lamp beads on the circuit board 30, thereby avoiding bright light from appearing at the connection seam between the two LED light boards and affecting the display effect.

[0040] Furthermore, a raised stop bar 120 extending toward the circuit board 30 is provided around the inner edge of the frame bracket 10 , and the inner edge of the light-shielding rubber strip 40 abuts against the raised stop bar 120 .

[0041] Specifically, the inner and outer heights of the frame bracket 10 are not consistent. The raised guard bar 120 is provided along the inner edge of the side facing the circuit board 30. The raised guard bar 120 extends toward the circuit board 30, and the inner edge of the shading strip 40 rests on the raised guard bar 120, thereby making the two tightly connected.

[0042] Furthermore, a positioning protrusion is provided on the raised block strip 120 toward the light-shielding rubber strip 40, and a groove matching the positioning protrusion is provided on the inner edge of the light-shielding rubber strip 40. The positioning protrusion can be accommodated in the groove, thereby playing a positioning role for the installation of the light-shielding rubber strip 40.

[0043] Furthermore, in order to ensure the flatness of the circuit board 30 connected to the frame bracket 10 and to ensure the shading effect of the shading strip 40, the top of the raised guard bar 120 is flush with the top of the shading strip 40, that is, the height of the raised guard bar 120 is consistent with the thickness of the shading strip 40.

[0044] In addition, in other preferred embodiments of the present invention, a positioning post 1101 facing the circuit board 30 is provided at the bottom of the receiving groove 110 , and a positioning hole 210 for accommodating the positioning post 1101 is provided on the magnet 20 .

[0045] Specifically, the positioning post 1101 is arranged at the bottom of the accommodating groove 110 and extends toward the direction of the circuit board 30, and a plurality of positioning posts 1101 are provided at the bottom of the accommodating groove 110. These positioning posts 1101 are arranged in a fool-proof form to avoid errors when installing the magnet; the positioning hole 210 is provided on the magnet 20, and the aperture of the positioning hole 210 is slightly larger than the outer diameter of the positioning post 1101 to prevent the positioning hole 210 from accommodating the positioning post 1101.

[0046] Here, the magnet can be quickly assembled by providing the positioning column 1101 and the positioning hole 210 .

[0047] Furthermore, please combine Figure 5a and Figure 5b In other preferred embodiments of the present invention, the magnetic pole distribution of the magnets 20 on the two opposite sides of the frame bracket 10 is the same.

[0048] Specifically, two adjacent LED light boards are respectively denoted as X1 and X2. The S pole and N pole of the magnet 20 on the opposite sides of the frame bracket 10 of X1 and X2 are the same. On the one hand, such a design facilitates its production due to the same product form. On the other hand, it can also ensure that the LED light boards can be spliced ​​and expanded at will to meet the needs of large-area display screens.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention, rather than to limit them. Although the embodiments of the present invention have been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
