Description

Technical Field

[0001] This utility model relates to the field of LED display module technology, and in particular to an arc-shaped transition LED display cabinet. Background Technology

[0002] With the continuous development of LED display technology, various LED display devices have appeared in people's lives. Compared with traditional flat LED display devices, curved LED displays have greater visual appeal and artistry, and can better adapt to some special scenarios and environments, such as curved walls and curved building facades. They are widely used in indoor and outdoor advertising, stage performances, stadiums, conferences and exhibitions, and other venues.

[0003] Currently, existing LED curved displays typically use small-sized strip-shaped or head-shaped display modules fixed to a curved frame, relying on the pre-defined curved shape of the frame for shaping. This curved frame (i.e., the display cabinet) is mostly made of sheet metal, bent into the required curve, and the components are fixed together by welding. While this process is economical, the sheet metal frame is heavy, and the sheet metal parts are prone to deformation after bending and welding, resulting in poor precision when installing the display modules. Furthermore, the welding of the components makes disassembly and assembly of the curved frame inconvenient, affecting its handling and transport. Therefore, it is necessary to improve the existing display cabinet technology. Utility Model Content

[0004] The purpose of this utility model is to provide an arc-shaped transition LED display cabinet that is easy to disassemble and assemble with good assembly precision.

[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions: An arc-shaped transition LED display cabinet includes a main frame, a fixed panel, and an electrical control box. The main frame has a first fixing hole on the front side and a hook on the rear side. The fixed panel is installed on the front side of the main frame through the first fixing hole, and the control box is installed on the rear side of the main frame through the hook. The fixed panel is continuously bent laterally to form an arc-shaped structure, and mounting holes corresponding to the first fixing hole are opened on the fixed panel. The fixed panel also has several clearance holes, and a fixing part is formed between adjacent clearance holes. Snap-fit ​​holes are respectively provided at both ends of the fixing part.

[0006] In one embodiment, the main frame includes two sets of supporting profiles and two sets of curved end plates. The two sets of supporting profiles are arranged vertically at intervals, and the two sets of curved end plates are respectively connected to the top and bottom ends of the two sets of supporting profiles. The two sets of curved end plates are also connected to support bars, which are located between the two sets of supporting profiles. A first fixing hole is opened on the front side of the supporting profile, and a hook is located on the rear side of the support bar.

[0007] In one embodiment, the top and bottom ends of the supporting profile are respectively provided with second fixing holes, and the left and right sides of the curved end plate are respectively provided with connecting holes corresponding to the second fixing holes.

[0008] In one embodiment, the front side of the arcuate end plate has an arcuate edge that mates with the fixed panel.

[0009] In one embodiment, the support profile has wire holes.

[0010] In one embodiment, the top surface of the support profile is provided with a positioning post, and the bottom end is provided with a positioning hole.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figures 1 to 6 An arc-shaped transition LED display cabinet includes a main frame 100, a fixed panel 200, and an electrical control box 300. The main frame 100 has a first fixing hole 110 on the front side and a hook 120 on the rear side. The fixed panel 200 is installed on the front side of the main frame 100 through the first fixing hole 110, and the control box 300 is set on the rear side of the main frame 100 through the hook 120. The fixed panel 200 is continuously bent in the horizontal direction to form an arc-shaped structure, and mounting holes 210 corresponding to the first fixing hole 110 are opened on the fixed panel 200. The fixed panel 200 also has several clearance holes 220. A fixing part 230 is formed between adjacent clearance holes 220. Snap-fit ​​holes 240 are respectively provided at both ends of the fixing part 230.

[0022] Specifically, in this embodiment, first fixing holes 110 are respectively provided at the four corners of the front side of the main frame 100, and hooks 120 are provided at the rear side of the main frame 100. The fixing panel 200 is continuously bent in the lateral direction to form the required arc structure. Mounting holes 210 are respectively provided at the four corners of the fixing panel 200. The mounting holes 210 of the fixing panel 200 are respectively aligned with the first fixing holes 110 of the main frame 100, and the fixing panel 200 can be installed on the front side of the main frame 100 by screws, realizing the mechanical connection between the fixing panel 200 and the main frame 100. The fixed panel 200 is used for the installation of the display module, while the electrical control box 300 is directly hung on the rear side of the main frame 100 via the hook 120. The electrical control box 300 is used for the installation of electrical control components. This mechanical assembly and connection method avoids welding and fixing between the fixed panel 200, the electrical control box 300 and the main frame 400, so that the display cabinet can be easily disassembled and assembled, facilitating later handling and transportation. Since there is no need to weld the fixed panel 200, it will not cause deformation of the fixed panel 200, ensuring the curvature accuracy of the fixed panel 200 and making the assembly accuracy between the display module and the fixed panel 200 better.

[0023] In addition, to facilitate the assembly between the display module and the display cabinet, clearance holes 220 are provided on the fixed panel 200. The clearance holes 220 allow the display module to be located on the front side of the fixed panel 200, while the control board of the display module is located on the rear side of the fixed panel 200, so as to facilitate electrical connection with the electrical control components in the electrical control box 300. A fixing part 230 is formed between two adjacent clearance holes 220, and a snap-fit ​​hole 240 is provided at both ends of the fixing part 230. The upper and lower ends of the bar display module can be snapped and fixed through the snap-fit ​​hole 240 respectively (the back of the bar display module has a rotatable buckle. When the rotatable buckle is inserted into the snap-fit ​​hole, the rotatable buckle can be rotated 90° to limit the display module. This structure is existing technology and will not be described in detail here). The clearance holes 220 and snap-fit ​​holes 240 enable the display module and the display cabinet to be assembled quickly and conveniently, and the assembly structure is reasonable.

[0024] Furthermore, in this embodiment, the main frame 100, the fixing panel 200, and the electrical control box 300 are all made of aluminum. The main frame 100, fixing panel 200, and electrical control box 300, all made of aluminum, have a robust and stable structure that is not easily deformed. They are also lighter than sheet metal. Combined with the clearance holes 220, this significantly improves the overall rigidity and stability of the display screen enclosure and reduces its overall weight.

[0025] Of course, since the display module is installed on the fixed panel 200, in order to ensure the overall strength of the fixed panel 200, a reinforcing rib 250 is provided on the rear side of the fixing part 230 of the fixed panel 200. The reinforcing rib 250 can improve the overall rigidity and strength of the fixed panel 200, thereby ensuring the installation of the display module.

[0026] Please see Figures 3 to 5 In this embodiment, the main frame 100 includes two sets of supporting profiles 130 and two sets of curved end plates 140. The two sets of supporting profiles 130 are arranged vertically at intervals. The two sets of curved end plates 140 are respectively connected to the top and bottom ends of the two sets of supporting profiles 130. The two sets of curved end plates 140 are also connected to support bars 150. The support bars 150 are located between the two sets of supporting profiles 130. The first fixing hole 110 is opened on the front side of the supporting profile 130, and the hook 120 is located on the rear side of the support bar 150.

[0027] Two sets of supporting profiles 130 are erected and spaced apart. The left and right sides of one curved end plate 140 are connected to the tops of the two sets of supporting profiles 130, and the left and right sides of the other curved end plate 140 are connected to the bottoms of the two sets of supporting profiles 130. This connection forms the main frame 100. First fixing holes 110 are formed on the front sides of the top and bottom of each of the two sets of supporting profiles 130, creating four first fixing holes 110. These four first fixing holes 110 are used to fix and assemble the four corners of the fixing panel 200. Furthermore, to achieve... To facilitate the assembly of the electrical control box 300 and ensure the stability of the main frame 100, two support bars 150 are connected between the upper and lower sets of curved end plates 140. The upper and lower ends of the two support bars 150 are connected to the two sets of curved end plates 140 respectively. The connection method can also be fixed with screws (mechanical connection). Hooks 120 are provided on the rear side of the two support bars 150. The electrical control box 300 can be hung by the hooks 120, which makes it easy to assemble and disassemble the electrical control box 300 and the main frame 100. At the same time, it also makes it easy to assemble and disassemble the main frame 100, and the two support bars 150 can improve its stability.

[0028] To achieve the connection and fixation between the curved end plate 140 and the supporting profile 130, in this embodiment, second fixing holes 131 are respectively provided at the top and bottom ends of the supporting profile 130, and connecting holes 141 corresponding to the second fixing holes 131 are respectively provided on the left and right sides of the curved end plate 140. By aligning the connecting holes 141 on the curved end plate 140 with the second fixing holes 131 on the supporting profile 130, and then locking them by passing screws through the connecting holes 141 and the second fixing holes 131, a mechanical connection between the curved end plate 140 and the supporting profile 130 can be achieved, thereby making it convenient to assemble and disassemble the curved end plate 140 and the supporting profile 130.

[0029] Furthermore, to ensure proper assembly between the fixed panel 200 and the main frame 100, the curved end plate 140 in this embodiment has a curved edge on its front side that mates with the fixed panel 200. By mates the curved edge on the front side of the curved end plate 140 with the curved shape of the fixed panel 200, the installation and fixation of the curved fixed panel 200 can be ensured, thus making its structural design reasonable.

[0030] Please see Figure 6 In order to realize the assembly between the electrical control box 300 and the main frame 100, the electrical control box 300 includes a box body 310 and a box cover 320 covering the box body 310. Hanging edge portions 330 are respectively provided on both sides of the box body 310, and hanging holes 340 corresponding to the hooks 120 are opened on the hanging edge portions 330. At the same time, a wire hole 350 is opened on the back of the box body 310, and a protective cover 360 is provided at the wire hole 350.

[0031] By extending hanging edges 330 on both sides of the back of the box 310, and providing hanging holes 340 in the hanging edges 330, the connection between the control box 300 and the main frame 100 is realized through the interaction of the hanging holes 340 and the hooks 120 on the support strip 150. This makes it easy to assemble and disassemble the control box 300 and the main frame 100. The electrical control components can be installed inside the box 310 and covered by the box cover 320 to effectively prevent external dust from entering. Of course, since the display module installed on the fixed panel 200 needs to be electrically connected to the electrical control components inside the control box 300, a wire hole 350 is also provided on the back of the box 310. The wire is led out from the wire hole 350, and a protective cover 360 is provided at the wire hole 350. The bottom of the protective cover 360 has an opening for wire passage. The bottom opening can effectively prevent liquid from flowing into the control box 300, thereby improving the dustproof and waterproof performance.

[0032] Finally, please see Figure 4 and Figure 5Through the curved transition LED display cabinet in this embodiment, a transition splicing with a straight screen cabinet can be achieved, thereby realizing 2D and 3D display effects. In order to achieve splicing, a positioning post 170 is provided on the top surface of the support profile 130, and a positioning hole (not shown in the figure) is provided at the bottom. When two sets of curved transition LED display cabinets are spliced ​​vertically, the positioning post 170 on the top surface of the support profile 130 of the lower curved transition LED display cabinet will be inserted into the positioning hole on the bottom surface of the support profile 130 of the upper curved transition LED display cabinet, so as to realize the positioning splicing between the two adjacent sets of curved transition LED display cabinets. At the same time, a wire hole 160 is also provided on the support profile 130, which facilitates the mutual wiring between adjacent display modules.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
