[0003] In related technologies, the cabinet frame typically includes a main frame and reinforcing beams that are set inside and connected to the main frame. The control box is usually connected to the rear side of the reinforcing beams, which makes the overall thickness of the LED cabinet relatively thick. Utility Model Content

[0004] The main objective of this invention is to provide an LED cabinet and an LED display device having the same, in order to solve the problem of the large thickness of LED cabinets in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, an LED enclosure is provided, comprising: a frame, including a frame body and a reinforcing beam, the frame body enclosing a receiving space, the reinforcing beam being disposed within the receiving space, and both ends of the reinforcing beam being connected to the frame body; an LED display module, disposed on the front side of the frame and connected to the frame body; and a control box, disposed within the receiving space and connected to the reinforcing beam, the control box being electrically connected to the LED display module, and the control box being connected to the side of the reinforcing beam.

[0006] Furthermore, the reinforced beam includes a beam body and a mounting base, with the mounting base located on the side of the beam body and the control box connected to the mounting base.

[0007] Furthermore, the control box includes a box body, fasteners, and lugs disposed at the ends of the box body. The fasteners pass through the lugs and the mounting base to connect the control box and the reinforcing beam; and / or, the mounting base protrudes rearward from the beam body; and / or, the beam body and the mounting base are integrally formed structures.

[0008] Furthermore, the mounting base includes a connecting plate, a mounting plate, and a reinforcing plate. The connecting plate and the mounting plate are set at an angle. The connecting plate is connected to the main beam body. The control box is mounted on the mounting plate. The reinforcing plate is connected to both the connecting plate and the mounting plate.

[0009] Furthermore, the mounting plate has a heat-conducting surface, which is heat-conductingly connected to the control box.

[0010] Furthermore, the control box has a plug-in interface on its side, wherein the mounting plate has a relief recess corresponding to the plug-in interface on its rear side; and / or, the connecting plate has an observation hole corresponding to the plug-in interface.

[0011] Furthermore, the LED enclosure also includes a rear shell located on the rear side of the frame and connected to the frame, and a support column is provided on the rear side of the reinforcing beam, which can abut against the rear shell to support the rear shell.

[0012] Furthermore, there are multiple support columns, which are spaced apart along the extension direction of the reinforcing beam. The distance between the support column closest to the frame body and the frame body is greater than or equal to 2.5cm and less than or equal to 5.5cm.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] like Figures 1 to 6 As shown, this application provides an LED enclosure. An embodiment of the LED enclosure of this application includes: a frame 10, an LED display module, and a control box 20. The frame 10 includes a frame body 11 and a reinforcing beam 12. The frame body 11 encloses a receiving space 13. The reinforcing beam 12 is disposed within the receiving space 13, and both ends of the reinforcing beam 12 are connected to the frame body 11. The LED display module is disposed on the front side of the frame 10 and connected to the frame 10. The control box 20 is disposed within the receiving space 13 and connected to the reinforcing beam 12. The control box 20 is electrically connected to the LED display module and is connected to the side of the reinforcing beam 12.

[0031] Applying the technical solution of this embodiment, the frame 10 includes a frame body 11 and a reinforcing beam 12. The frame body 11 encloses a receiving space 13, which is used to receive other components of the LED cabinet. The frame body 11 provides basic support. The reinforcing beam 12 is disposed within the receiving space 13, and both ends of the reinforcing beam 12 are connected to the frame body 11. The reinforcing beam 12 is used to improve the structural strength of the frame 10. The LED display module is disposed on the front side of the frame 10 and connected to the frame 10. The LED display module is used to realize the screen display function. The control box 20 is electrically connected to the LED display module. The control box 20 is used to control the LED display module for image display. The control box 20 is disposed within the accommodating space 13 and connected to the reinforcing beam 12. The control box 20 is connected to the side of the reinforcing beam 12. Compared to related technologies where the control box is located on the rear side of the reinforcing beam (i.e., the control box and the reinforcing beam are stacked in the front-to-back direction), in this embodiment, the control box 20 is connected to the side of the reinforcing beam 12. This reduces the thickness of the structure formed by the connection of the control box 20 and the reinforcing beam 12, thereby reducing the thickness of the LED housing. Therefore, the technical solution of this embodiment effectively solves the problem of the large thickness of the LED housing in related technologies.

[0032] It should be noted that when the LED cabinet is mounted on a wall or other support, in this article, the term "front" refers to the direction in which the LED cabinet faces the viewer, "back" refers to the direction in which the LED cabinet is away from the viewer, "up" refers to the direction in which the LED cabinet is away from the ground, and "down" refers to the direction in which the LED cabinet is close to the ground.

[0033] like Figures 1 to 8 As shown, the reinforcing beam 12 includes a beam body 121 and a mounting base 122. The mounting base 122 is located on the side of the beam body 121, and the control box 20 is connected to the mounting base 122. Specifically, in this embodiment, the frame body 11 is a rectangular frame structure. The two ends of the beam body 121 are connected to the upper and lower sides of the frame body 11 to strengthen the structural strength of the frame 10. The beam body 121 extends vertically. The mounting base 122 is connected to the side of the beam body 121 and is used to install the control box 20, thereby enabling the control box 20 to be connected to the side of the reinforcing beam 12. In addition, there are multiple reinforcing beams 12, which are spaced apart in the transverse direction. The multiple reinforcing beams 12 further enhance the structural strength of the frame 10. The control box 20 is connected to the side of the reinforcing beam 12 located in the middle, resulting in a better overall layout.

[0034] like Figure 6 As shown, the control box 20 includes a box body 21, fasteners, and lugs 23 located at the ends of the box body 21. The fasteners pass through the lugs 23 and the mounting base 122 to connect the control box 20 and the reinforcing beam 12. Specifically, the fasteners are fastening screws, and the lugs 23 are plate-shaped structures. There are two lugs 23, which are respectively located at the upper and lower ends of the box body 21. The fasteners pass through the lugs 23 and the mounting base 122 in the transverse direction to connect the control box 20 and the reinforcing beam 12. This configuration has the advantages of simple structure, stable connection, and convenient operation, which facilitates the maintenance of the control box 20 by the staff.

[0035] like Figure 4 As shown, the mounting base 122 protrudes rearward from the beam body 121. Specifically, in the front-rear direction, the size of the mounting base 122 is larger than the size of the beam body 121. The larger size of the mounting base 122 can increase the connection strength between the control box 20 and the reinforcing beam 12, making the connection between the control box 20 and the reinforcing beam 12 more stable.

[0036] Furthermore, in this embodiment, the beam body 121 and the mounting base 122 are integrally formed structures. Specifically, in this embodiment, the frame body 11 and the reinforcing beam 12 are both integrally formed structures, using die casting. Die casting is a manufacturing process in which metal or alloy is injected into a mold under high pressure, and after cooling and solidification, a part is formed. The advantages of using die casting for integral forming are mainly reflected in the following aspects: First, die casting can achieve efficient production. Because it uses a mold for one-time forming, production efficiency can be greatly improved and production costs reduced. Compared with traditional processing methods, die casting can complete the manufacturing of the frame 10 more quickly and is suitable for large-scale production. Second, die casting can ensure the precision and surface quality of each component on the frame 10. Because it uses mold forming, the influence of human operation on the frame 10 can be reduced, ensuring the precision and consistency of the frame 10. At the same time, die casting can reduce material waste to a certain extent and improve material utilization. In addition, die casting can manufacture frames 10 with complex shapes. By designing different molds, frames 10 of various shapes and structures can be produced to meet different needs. Meanwhile, die casting can produce complex structures such as thin-walled parts and hollowed-out parts on the frame 10. Finally, die casting can improve the strength and wear resistance of the frame 10. Due to the good fluidity of the metal during the die casting process, a dense grain structure can be formed, giving the frame 10 higher strength and hardness. At the same time, die casting can achieve one-piece molding, reducing weaknesses at joints and welds, and improving the wear resistance and durability of the frame 10.

[0037] like Figure 4 as well as Figures 6 to 8 As shown, the mounting base 122 includes a connecting plate 1221, a mounting plate 1222, and a reinforcing plate 1223. The connecting plate 1221 and the mounting plate 1222 are arranged at an angle. The connecting plate 1221 is connected to the beam body 121. The control box 20 is mounted on the mounting plate 1222. The reinforcing plate 1223 is connected to both the connecting plate 1221 and the mounting plate 1222. In this embodiment, the connecting plate 1221 and the mounting plate 1222 are arranged perpendicularly. The connecting plate 1221 is a horizontal plate, and the mounting plate 1222 is a vertical plate. The reinforcing plate 1223 is connected between the connecting plate 1221 and the mounting plate 1222 to enhance the structural strength of the mounting base 122.

[0038] like Figure 8As shown, the mounting plate 1222 has a heat-conducting surface 1224, which is thermally connected to the control box 20. Specifically, the one-piece molded frame 10 is painted to extend its service life. On the side of the mounting plate 1222 facing the control box 20, the protective paint on this side is removed by a cutting process, exposing the metal part. This exposed metal part forms the heat-conducting surface 1224, which has good thermal conductivity. The heat-conducting surface 1224 is thermally connected to the control box 20, so that when the LED cabinet is working, the heat generated by the control box 20 is transferred to the frame 10 through the heat-conducting surface 1224, thereby dissipating heat from the control box 20.

[0039] like Figure 7 as well as Figure 8 As shown, the control box 20 has a plug-in interface 24 on its side, and the mounting plate 1222 has a relief notch 1225 corresponding to the plug-in interface on its rear side. Specifically, in this embodiment, the relief notch 1225 is provided to avoid the plug-in interface, so that the mounting plate 1222 will not interfere with the connecting wires connecting the control box 20 and the LED display module.

[0040] like Figure 1 as well as Figure 2 As shown, the connecting plate 1221 has an observation hole 1226 corresponding to the plug interface. This design allows the operator to observe whether the connecting cable is properly plugged into the control box 20 when using the connecting cable, facilitating the operator's installation and disassembly work.

[0041] like Figure 1 , Figure 2 , Figure 7 as well as Figure 8 As shown, the LED enclosure also includes a rear shell disposed on the rear side of the frame 10 and connected to the frame 10. A support column 123 is disposed on the rear side of the reinforcing beam 12, and the support column 123 can abut against the rear shell to support it. Specifically, the provision of the support column 123 enables the support column 123 to abut against the rear shell when the rear shell is subjected to force and deforms inward, thereby preventing the rear shell from deforming and compressing other components within the accommodating space 13, and ensuring the safety of the LED enclosure.

[0042] like Figure 1 , Figure 2 , Figure 4 , Figure 7 as well as Figure 8As shown, there are multiple support columns 123, which are spaced apart along the extension direction of the reinforcing beam 12. The distance d between the support column 123 near the frame body 11 and the frame body 11 is greater than or equal to 2.5 cm and less than or equal to 5.5 cm. Specifically, during the die casting process, the molten metal enters the mold forming the reinforcing beam 12 from the corresponding part of the connection between the frame body 11 and the reinforcing beam 12 (the mold feed point of the reinforcing beam part), thus forming the reinforcing beam 12. Due to the high temperature of the molten metal, some impurities in the molten metal accumulate in the pits of the mold (the pits correspond to the support columns 123). After cooling and solidification, the support columns 123 are formed, which can cover these impurities. Furthermore, the arrangement of the support columns 123 also facilitates ejector pin demolding. The support column 123, which meets the above distance conditions, can form a feeding buffer zone between the mold feeding point and the recess in the reinforcing beam section of the molten metal. This prevents the molten metal from directly colliding violently with impurities accumulated in the recess, thus avoiding burning and bulging at the mold feeding point in the reinforcing beam section and reducing the possibility of manufacturing a frame 10 that does not meet quality requirements. The distance d between the support column 123 near the frame body 11 and the frame body 11 can be 2.5cm, 3cm, 3.2cm, 4.1cm, 4.7cm, or 5.5cm. It should be noted that "the distance d between the support column 123 near the frame body 11 and the frame body 11" refers to the distance between the center point of the support column 123 near the frame body 11 and the edge of the frame body 11 near the support column 123.

[0043] like Figure 4 As shown, the cross-sectional area of ​​the support column 123 gradually decreases from front to back. This arrangement is to make the reinforcing beam 12 easier to demold.

[0044] This application also provides an LED display device, which includes an LED cabinet, wherein the LED cabinet is the aforementioned LED cabinet. The aforementioned LED cabinet effectively solves the problem of large thickness in related technologies, and the LED display device having the aforementioned LED cabinet also has the above-mentioned advantages.
