Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and more specifically, to an LED cabinet and an LED display device having the same. Background Technology

[0002] LED displays have the following main characteristics: clear images, vibrant colors, good stability, high brightness, high luminous efficiency, long lifespan, low power consumption, and unlimited size. As a large-scale LED display device, an LED display is typically composed of multiple relatively smaller LED cabinets spliced ​​together. Currently, in related fields, the installation structure of LED displays (such as mounting brackets or mounting surfaces) is usually not a high-precision planar structure. Furthermore, there are certain processing errors in the LED cabinet manufacturing process. Therefore, during the splicing of LED cabinets, inconsistencies in the seams between them often occur. Workers need to adjust these seams to reduce their impact on the display effect. However, existing connection and installation structures and LED cabinet connection structures (such as magnetic structures) are not conducive to adjusting the seams. Utility Model Content

[0003] The main objective of this invention is to provide an LED cabinet and an LED display device having the same, so as to solve the problem of difficult seam adjustment of LED cabinets in related technologies.

[0004] To achieve the above objectives, according to one aspect of the present invention, an LED enclosure is provided, comprising: a support frame structure; a light panel disposed on the front side of the support frame structure; and a connecting assembly disposed on the rear side of the support frame structure. The connecting assembly includes a first connecting member and a second connecting member sequentially connected in a direction away from the support frame structure. The first connecting member is rotatably connected to the support frame structure so that the angle between the support frame structure and the first connecting member is adjustable. The second connecting member is movable relative to the first connecting member so that the length of the connecting assembly is adjustable. The second connecting member is used to connect to a back frame.

[0005] Furthermore, one of the first connector and the second connector includes a plug-in sleeve, and the other of the first connector and the second connector includes a plug-in portion that is slidably inserted into the plug-in sleeve.

[0006] Furthermore, the plug-in tube is provided with an anti-detachment groove, and the plug-in part is provided with a sliding shaft. The sliding shaft is inserted into the anti-detachment groove and can cooperate with the groove wall stop of the anti-detachment groove to limit the separation of the plug-in tube and the plug-in part; and / or, the end of the second connector away from the support frame structure is provided with a rotating connection part, which is used to connect with the back frame and is rotatably connected to the second connector.

[0007] Furthermore, the first connector also includes a first sub-connector and a second sub-connector. The first sub-connector is connected to the second connector, and the second sub-connector is connected to the support frame structure and has a first rotation axis. The first sub-connector and the second sub-connector are rotatably arranged and have a second rotation axis. The first rotation axis and the second rotation axis are set at an angle.

[0008] Furthermore, one of the first sub-connector and the second sub-connector includes a mounting base, and the other of the first sub-connector and the second sub-connector includes a connecting block, which is rotatably mounted on the mounting base.

[0009] Furthermore, the mounting base includes a first plate and a second plate that are opposite to and spaced apart, a connecting block is disposed between the first plate and the second plate, and the connecting block has a first rotating shaft that is inserted into the first plate and / or the second plate.

[0010] Furthermore, the support frame structure includes a vertical frame and multiple horizontal frames, with the multiple horizontal frames spaced apart. The light panel is connected to the horizontal frames, and the vertical frame is connected to all of the multiple horizontal frames. The first connecting piece is connected to the vertical frame.

[0011] Furthermore, the vertical frame includes a first side plate and a second side plate that are opposite to and spaced apart. One end of a first connector is disposed between the first side plate and the second side plate. The first connector has a second rotating shaft that is inserted into the first side plate and / or the second side plate.

[0012] Furthermore, the LED enclosure also includes a power supply box assembly electrically connected to the light panel. The vertical frame has a hanging interface, and the power supply box assembly has a hook portion that engages with the hanging interface to allow the power supply box assembly to be detachably connected to the vertical frame.

[0013] According to another aspect of the present invention, an LED display device is provided, including an LED cabinet and a back frame, wherein the LED cabinet and the back frame are connected, and the LED cabinet is the aforementioned LED cabinet.

[0014] Applying the technical solution of this utility model, the support frame structure provides an installation base for other components of the LED cabinet. The lamp panel is located on the front side of the support frame structure to realize the display function. The connecting assembly is located on the rear side of the support frame structure and is used to connect the LED cabinet to the back frame. The connecting assembly includes a first connector and a second connector connected sequentially in the direction away from the support frame structure. The first connector is rotatably connected to the support frame structure so that the angle between the support frame structure and the first connector is adjustable. As needed, the operator adjusts the first connector and the support frame structure to change the angle between the support frame structure and the first connector, thereby allowing the LED cabinet to be angled with adjacent LED cabinets. The angle changes, thus allowing adjustment of the seam between adjacent LED cabinets; the second connector connects to the back frame and can move relative to the first connector, allowing the length of the connecting assembly to be adjusted. Workers adjust the second and first connectors as needed to adjust the length of the connecting assembly, thereby adjusting the distance between the light panel and the back frame, and thus adjusting the positional relationship of adjacent LED cabinets in the front-back direction. By coordinating the adjustment of the first and second connectors, workers can adjust adjacent LED cabinets in terms of both angular and positional relationships, making it relatively easy to reduce the seam between adjacent LED cabinets, thereby ensuring a better display effect.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0028] As Figures 1 to 5 shown, the present application provides an LED box body. The embodiments of the LED box body of the present application include: a support frame structure 10, a lamp board 20, and a connection component 30; the lamp board 20 is arranged on the front side of the support frame structure 10; the connection component � is arranged on the rear side of the support frame structure 10. The connection component 30 includes a first connection piece 31 and a second connection piece 32 connected in sequence in the direction away from the support frame structure 10. The first connection piece 31 is rotatably connected to the support frame structure 10 so that the angle between the support frame structure 10 and the first connection piece 31 can be adjusted. The second connection piece 32 can move relative to the first connection piece 31 so that the length of the connection component 30 can be adjusted. The second connection piece 32 is used to connect to the back frame 3.

[0029] Applying the technical solution of this embodiment, the support frame structure 10 provides an installation base for other components of the LED cabinet. The lamp panel 20 is disposed on the front side of the support frame structure 10 to realize the display function. The connecting assembly 30 is disposed on the rear side of the support frame structure 10. The connecting assembly 30 is used to connect the LED cabinet to the back frame 3. The connecting assembly 30 includes a first connecting member 31 and a second connecting member 32 connected sequentially in the direction away from the support frame structure 10. The first connecting member 31 is rotatably connected to the support frame structure 10 so that the angle between the support frame structure 10 and the first connecting member 31 is adjustable. As needed, the operator adjusts the first connecting member 31 and the support frame structure 10 to change the angle between the support frame structure 10 and the first connecting member 31, thereby enabling the LED cabinet to connect with adjacent... The angle of the LED cabinet changes, thereby adjusting the seam between adjacent LED cabinets. The second connector 32 is connected to the back frame 3 and can move relative to the first connector 31, allowing the length of the connecting assembly 30 to be adjusted. Operators can adjust the length of the connecting assembly 30 by adjusting the second connector 32 and the first connector 31 as needed, thereby adjusting the distance between the light panel 20 and the back frame 3, and thus adjusting the positional relationship of adjacent LED cabinets in the front-to-back direction. By coordinating the adjustment of the first connector 31 and the second connector 32, operators can adjust adjacent LED cabinets in terms of both angle and positional relationship, thus easily reducing the seam between adjacent LED cabinets and ensuring a better display effect. Therefore, the technical solution of this embodiment can effectively solve the problem of difficult seam adjustment of LED cabinets in related technologies.

[0030] like Figure 2 as well as Figure 5 As shown, one of the first connector 31 and the second connector 32 includes a plug-in tube 311, and the other of the first connector and the second connector 32 includes a plug-in portion 321, which is slidably inserted into the plug-in tube 311. Specifically, by making the plug-in portion 321 slidably inserted into the plug-in tube 311, the second connector 32 can move relative to the first connector 31, thereby making the length of the connecting assembly 30 adjustable. The plug-in tube 311 and the plug-in portion 321 have the advantage of being easy to manufacture. In this embodiment, the first connector 31 includes a plug-in tube 311, and the second connector 32 includes a plug-in portion 321. The end of the plug-in portion 321 near the support frame structure 10 is slidably inserted into the end of the plug-in tube 311 away from the support frame structure 10.

[0031] like Figure 2 as well as Figure 5As shown, the plug-in cylinder 311 is provided with an anti-detachment groove 312, and the plug-in portion 321 is provided with a sliding shaft. The sliding shaft is inserted into the anti-detachment groove 312 and can cooperate with the groove wall stop of the anti-detachment groove 312 to restrict the separation of the plug-in cylinder 311 and the plug-in portion 321. Specifically, the anti-detachment groove 312 extends along the length direction of the plug-in cylinder 311. When the plug-in portion 321 and the plug-in cylinder 311 slide relative to each other, the sliding shaft slides in the anti-detachment groove 312. When the sliding shaft slides to its limit position, the sliding shaft cooperates with the groove wall stop of the anti-detachment groove 312 to restrict the separation of the plug-in cylinder 311 and the plug-in portion 321, thereby preventing the first connecting member 31 and the second connecting member 32 from disengaging.

[0032] In addition, such as Figure 2 as well as Figure 5 As shown, the second connector 32 has a rotating connection portion 322 at the end away from the support frame structure 10. The rotating connection portion 322 is used to connect to the back frame 3, and the rotating connection portion 322 is rotatably connected to the second connector 32. In this embodiment, the rotating connection portion 322 is connected to the end of the insertion portion 321 away from the support frame structure 10. This arrangement allows both the end of the insertion portion 321 away from the support frame structure 10 and the end of the insertion tube 311 near the support frame structure 10 to rotate, thereby enhancing the flexibility of the adjustable position of the LED cabinet. In this embodiment, the rotation axis between the rotating connection portion 322 and the second connector 32, as well as the rotation axis between the second connector 32 and the first connector 31 (i.e., the second rotation axis 2 mentioned later), both extend in the vertical direction.

[0033] More specifically, such as Figure 2 as well as Figure 5 As shown, the first connector 31 also includes a first sub-connector 313 and a second sub-connector 314. The first sub-connector 313 is connected to the second connector 32, and the second sub-connector 314 is connected to the support frame structure 10 and has a first rotation axis 1. The first sub-connector 313 and the second sub-connector 314 are rotatably arranged and have a second rotation axis 2. The first rotation axis 1 and the second rotation axis 2 are set at an angle. In this embodiment, the second rotation axis 2 extends vertically, and the first rotation axis 1 extends horizontally. By using the angled first rotation axis 1 and the second rotation axis 2, the LED cabinet can rotate in more directions, allowing the LED cabinet to be angled to its adjacent LED cabinets in the vertical direction and its adjacent LED cabinets in the horizontal direction, thereby more comprehensively adjusting the seams between the LED cabinet and adjacent LED cabinets in different directions.

[0034] like Figure 2 as well as Figure 5As shown, one of the first sub-connector 313 and the second sub-connector 314 includes a mounting base 3141, and the other of the first sub-connector 313 and the second sub-connector 314 includes a connecting block 3131, which is rotatably mounted on the mounting base 3141. Specifically, the connecting block 3131 and the mounting base 3141 are rotatably engaged, thereby realizing the rotatable engagement between the first sub-connector 313 and the second sub-connector 314. The connecting block 3131 and the mounting base 3141 have the advantages of simple structure and easy processing.

[0035] like Figure 2 as well as Figure 5 As shown, the mounting base 3141 includes a first plate 3142 and a second plate 3143 that are opposite to and spaced apart. A connecting block 3131 is disposed between the first plate 3142 and the second plate 3143. The connecting block 3131 has a first rotating shaft, which is inserted into the first plate 3142 and / or the second plate 3143. Specifically, in this embodiment, the first rotating shaft extends in a vertical direction and is inserted into the first plate 3142 and the second plate 3143, thereby making the rotation of the connecting block 3131 more stable. The first plate 3142 and the second plate 3143 can restrict the movement of the connecting block 3131 along the direction of the second rotating axis 2.

[0036] like Figure 1 , Figure 3 as well as Figure 4 As shown, the support frame structure 10 includes a vertical frame 11 and multiple horizontal frames 12, which are spaced apart. The lamp panel 20 is connected to the horizontal frames 12, and the vertical frame 11 is connected to all the horizontal frames 12. The first connecting member 31 is connected to the vertical frame 11. Specifically, there are multiple lamp panels 20. In this embodiment, the horizontal frames 12 are designed as arc-shaped structures, and the lamp panels 20 are flexible lamp panels. The lamp panels 20 are placed on the horizontal frames 12, so that the shape of the lamp panels 20 matches the extended shape of the horizontal frames 12, thereby presenting a curved display effect. In other embodiments, the multiple lamp panels can also form a flat display effect. The vertical frame 11 enhances the structural strength of the multiple horizontal frames 12 and is used to connect with the connecting component 30.

[0037] like Figure 1 as well as Figure 2As shown, the vertical frame 11 includes a first side plate 111 and a second side plate 112 that are opposite to and spaced apart. One end of a first connecting member 31 is disposed between the first side plate 111 and the second side plate 112. The first connecting member 31 has a second rotating shaft, which is inserted into the first side plate 111 and / or the second side plate 112. Specifically, in this embodiment, the second rotating shaft extends in the lateral direction and is inserted into the first side plate 111 and the second side plate 112. The second rotating shaft is disposed on the side of the mounting base 3141 near the support frame structure 10, thereby making the rotation of the mounting base 3141 relative to the vertical frame 11 more stable. The first side plate 111 and the second side plate 112 can restrict the movement of the mounting base 3141 in the direction extending along the first rotating axis 1.

[0038] like Figures 1 to 3 As shown, the LED enclosure also includes a power supply box assembly 40 electrically connected to the light panel 20. The vertical frame 11 has a hanging interface 113, and the power supply box assembly 40 has a hook portion 41. The hook portion 41 and the hanging interface 113 are engaged to allow the power supply box assembly 40 to be detachably connected to the vertical frame 11. Specifically, the hook portion 41 and the hanging interface 113 allow workers to easily install and remove the power supply box assembly 40. Compared to the bolt connection method used in related technologies, the hook portion 41 and the hanging interface 113 solution eliminates the need for workers to perform multiple tightening operations. In addition, there are multiple hook portions 41 and the hanging interface 113, and they are arranged one-to-one. The hook portions 41 are spaced apart on both sides of the power supply box assembly 40 in the vertical direction, and the connection of the power supply box assembly 40 is more stable through multi-point connection. The hanging interface 113 is directly formed on the first side plate 111 and the second side plate 112.

[0039] This application also provides an LED display device, which includes an LED cabinet and a back frame 3, wherein the LED cabinet is the aforementioned LED cabinet. The aforementioned LED cabinet effectively solves the problem of difficult seam adjustment in related technologies, and the LED display device with the aforementioned LED cabinet also has the aforementioned advantages.
