[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown, the present application provides an LED display unit, and an embodiment of the LED display unit of the present application includes: a first LED display module 10, a second LED display module 20, and a magnetic leveling member 30; the first LED display module 10 includes a first module body 11 and a first magnetic member 12, and the first magnetic member 12 is arranged on the rear side of the first module body 11; the second LED display module 20 is arranged adjacent to the first LED display module 10, and the second LED display module 20 includes a second module body 21 and a second magnetic member 22, and the second magnetic member 22 is arranged on the rear side of the second module body 21, and the second magnetic member 22 is arranged adjacent to the first magnetic member 12; the magnetic leveling member 30 has an adjustment plane 31 that can simultaneously magnetically cooperate with the first magnetic member 12 and the second magnetic member 22, so that the display surface of the first LED display module 10 and the display surface of the second LED display module 20 are flush.

[0030] Applying the technical solution of this embodiment, the first LED display module 10 and the second LED display module 20 are both used to display images, and the second LED display module 20 is arranged adjacent to the first LED display module 10. The first LED display module 10 includes a first module body 11 and a first magnetic member 12, and the first magnetic member 12 is arranged on the rear side of the first module body 11. The second LED display module 20 includes a second module body 21 and a second magnetic member 22, and the second magnetic member 22 is arranged on the rear side of the second module body 21. The second magnetic member 22 is arranged adjacent to the first magnetic member 12. When the first LED display module 10 and the second LED display module 20 are spliced ​​together, the staff makes the magnetic leveling member 30 magnetically cooperate with the first magnetic member 12 and the second magnetic member 22, so that the adjustment plane 31 is aligned with the first magnetic member 12 and the second magnetic member 22. The first magnetic member 12 and the second magnetic member 22 are magnetically coupled. If the first LED display module 10 and the second LED display module 20 are misaligned in the front-to-back direction, for example, the first LED display module 10 is misaligned forward relative to the second LED display module 20 (that is, the first magnetic member 12 is misaligned forward relative to the second magnetic member 22), the magnetic leveling member 30 can pull the first magnetic member 12 backward and simultaneously push the second magnetic member 22 forward, so that the first magnetic member 12 and the second magnetic member 22 are aligned in the front-to-back direction, thereby eliminating the misalignment between the first LED display module 10 and the second LED display module 20, and further achieving the alignment of the display surface of the first LED display module 10 and the display surface of the second LED display module 20, thereby ensuring the display effect of the LED display unit. Therefore, the technical solution of this embodiment can effectively solve the problem of poor display effect in the related art.

[0031] It should be noted that the first LED display module 10 and the second LED display module 20 have similar structures and functions. When the LED display unit is hung on a wall or other support, in this document, the "front" used to describe the orientation refers to the direction of the LED display unit facing the viewer, the "back" refers to the direction of the LED display unit away from the viewer, the "up" refers to the direction of the LED display unit away from the ground, and the "down" refers to the direction of the LED display unit close to the ground.

[0032] like Figures 1 to 3As shown, the first module body 11 has a side 111, and the first magnetic member 12 is disposed near the side 111, and the first magnetic member 12 is located in the middle of the side 111. Specifically, in this embodiment, the first module body 11 and the second module body 21 are both rectangular parallelepiped structures, and the side 111 is the long side of the first module body 11 near the second module body 21. This arrangement can shorten the distance between the first magnetic member 12 and the second magnetic member 22, thereby reducing the size of the magnetic leveling member 30. The first magnetic member 12 being located in the middle of the side 111 means that the first magnetic member 12 is located at or near the center of the side 111. Specifically, if the length of the side 111 is divided into three equal parts, the first magnetic member 12 is located within the range of the middle of the three equal parts. This arrangement allows the force exerted by the magnetic leveling member 30 on the first module body 11 by pushing and pulling it to the middle, thereby achieving a better leveling effect.

[0033] like Figures 1 to 5 As shown, the magnetic leveling member 30 includes a leveling plate 32, and the front surface of the leveling plate 32 forms an leveling plane 31. The leveling plate 32 has the advantages of simple structure, easy processing and low cost. Compared with the solution in the related art of adjusting the length of the nut by screwing the nut to achieve leveling, the provision of the leveling plate 32 greatly simplifies the operation of the staff and improves work efficiency. In addition, in this embodiment, the leveling plate 32 is made of carbon steel plate or galvanized plate. Specifically, the carbon steel plate has the following advantages: the carbon steel plate has high strength, which enables it to have good load-bearing capacity in various applications; the carbon steel plate has high surface hardness, can resist wear and abrasion, and has a long service life; the carbon steel plate is easy to cut, bend and weld, and can be processed into various shapes as needed; the carbon steel plate has good plasticity, and its shape and performance can be changed by heat treatment or cold working; the raw material price of the carbon steel plate is relatively low, and the production cost is low. Galvanized sheet has the following advantages: the surface of the galvanized sheet is covered with a layer of zinc, which can effectively prevent corrosion and oxidation of the metal sheet and extend its service life; the surface of the galvanized sheet is high in hardness and wear-resistant, and is not easily damaged by external factors; the surface of the galvanized sheet is smooth and uniform; the galvanized sheet is easy to process and cut, and is suitable for various engineering and manufacturing fields.

[0034] like Figures 1 to 5As shown, the thickness of the adjustment plate 32 is greater than or equal to 1.2 mm and less than or equal to 2 mm. This setting can ensure that the magnetic attraction of the adjustment plate 32 is sufficiently large on the one hand, and on the other hand, the adjustment plate 32 is at an appropriate weight. Specifically, the thickness of the adjustment plate 32 can be 1.2 mm, 1.38 mm, 1.47 mm, 1.69 mm, 1.81 mm, or 2 mm. In this embodiment, the adjustment plate 32 is a rectangular plate. The length of the adjustment plate 32 is perpendicular to the adjacent sides of the first module body 11 and the second module body 21. The length of the adjustment plate 32 is greater than or equal to 8 cm and less than or equal to 11 cm, and can specifically be 8 mm, 8.5 mm, 9 mm, 10 mm, or 11 mm; the width of the adjustment plate 32 is greater than or equal to 5 cm and less than or equal to 8 cm, and can specifically be 5 mm, 5.5 mm, 6 mm, 7 mm, or 8 mm.

[0035] like Figures 1 to 5 As shown, the flatness of the adjustment plane 31 is greater than or equal to 0.13mm and less than or equal to 0.17mm. This arrangement, on the one hand, makes the adjustment plane 31 easy to process, and on the other hand, it can ensure that the magnetic attraction of the adjustment plane 31 to the magnetic component is more uniform, thereby ensuring the leveling effect. Specifically, the flatness of the adjustment plane 31 can be 0.13mm, 0.132mm, 0.138mm, 0.142mm, 0.16mm, and 0.17mm. In addition, in this embodiment, the first magnetic component 12 includes a mounting post and a magnet, the mounting post is connected to the first module body 11, and the magnet is arranged at the end of the mounting post away from the first module body 11. The magnet has a leveling mating surface that cooperates with the adjustment plane, and the flatness of the leveling mating surface is also greater than or equal to 0.13mm and less than or equal to 0.17mm.

[0036] like Figures 1 to 5 As shown, the adjustment plate 32 is provided with a limit portion 33, which cooperates with the first magnetic member 12 and the second magnetic member 22 to limit the position. Specifically, the provision of the limit portion 33 makes it easier for the operator to magnetically attract the magnetic member to the appropriate position on the adjustment surface 31 (in this embodiment, the middle position of the adjustment surface 31).

[0037] like Figure 3 as well as Figure 5As shown, the adjustment plate 32 is a rectangular plate, wherein the limiting portion 33 includes a first limiting plate 331 and a second limiting plate 332 arranged opposite each other. The first limiting plate 331 and the second limiting plate 332 extend along the length of the adjustment plate 32. The first magnetic member 12 and the second magnetic member 22 are both limited in the transverse direction between the first limiting plate 331 and the second limiting plate 332. Specifically, the first limiting plate 331 and the second limiting plate 332 are connected to the adjustment plate 32 by spot welding, and the first limiting plate 331 and the second limiting plate 332 can limit the transverse position of the magnetic members. In addition, the limiting portion 33 includes a third limiting plate 333 and a fourth limiting plate 334 that are arranged opposite to each other. The third limiting plate 333 is arranged at the first wide side of the adjusting plate 32, and the fourth limiting plate 334 is arranged at the second wide side of the adjusting plate 32. The third limiting plate 333 is located on the side of the first magnetic component 12 away from the second magnetic component 22 and cooperates with the first magnetic component 12 to limit the position. The fourth limiting plate 334 is located on the side of the second magnetic component 22 away from the first magnetic component 12 and cooperates with the second magnetic component 22 to limit the position. Specifically, the third limiting plate 333 and the fourth limiting plate 334 are formed by bending sheet metal. The third limiting plate 333 and the fourth limiting plate 334 can limit the first magnetic component 12 and the second magnetic component 22 in the vertical direction. The four limiting plates work together to achieve the effect of limiting the first magnetic component 12 and the second magnetic component 22 in multiple directions.

[0038] like Figure 4 as well as Figure 5 As shown, the leveling plate 32 is a rectangular plate, and gripping recesses 34 are provided on the long sides of the leveling plate 32. Specifically, gripping recesses 34 are provided in the middle of both long sides of the leveling plate 32. The gripping recesses 34 facilitate the operator's fingertips to grip the leveling plate 32, thereby facilitating the operator's operation. In addition, in this embodiment, the leveling plate 32 is also provided with multiple protrusions 35, with protrusions 35 provided at both ends of the gripping recess 34. The protrusions 35 extend in the opposite direction to the recessed direction of the gripping recess 34. The provision of the protrusions 35 increases the contact area between the leveling plate 32 and the fingertips, thereby providing a more stable grip for the operator.

[0039] like Figure 6 As shown, the present application also provides an LED display device, which includes a mounting frame 100 and an LED display unit connected to the mounting frame 100, wherein the LED display unit is the above-mentioned LED display unit. The above-mentioned LED display unit can effectively solve the problem of poor display effect in the related art, and the LED display device having the above-mentioned LED display unit also has the above-mentioned advantages.
