Description

Technical Field

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

[0002] LED display cabinets are typically the "smallest independent unit" of an LED large screen. They integrate the frame, power supply, control card, heat dissipation structure, and protective structure into a lightweight metal box structure. The front of the frame is used to fix or magnetically hold the LED display modules; the rear of the frame can be made into an openable compartment, with the power supply and control card mounted on the mounting beam. Cables are routed through concealed channels to correspond one-to-one with the LED display modules. Positioning posts, quick locks, and lifting pins are arranged around the perimeter, allowing for precise splicing and quick disassembly / reassembly. Ultimately, a large number of LED display cabinets can be seamlessly stacked like building blocks to form LED screens of any size and shape, accessible from both the front and rear. However, the frame is usually a one-piece molded structure. When the size of the LED display modules changes, the frame struggles to adapt to the changed modules, resulting in poor frame versatility.

[0026] like Figures 1 to 5As shown, this application provides an LED display cabinet. An embodiment of the LED display cabinet of this application includes: a frame structure 10 and an LED light panel; the frame structure 10 includes a first end frame 11, a main frame 12, a second end frame 13, a first connector 14 and a second connector 15. The main frame 12 is located between the first end frame 11 and the second end frame 13. The first connector 14 is used to connect the main frame 12 and the first end frame 11, and the second connector 15 is used to connect the main frame 12 and the second end frame 13, so that the first end frame 11 and the second end frame 13 can be provided with main frames 12 of different lengths; the LED light panel is disposed on the front side of the frame structure 10.

[0027] Using the technical solution of this embodiment, the LED light panel is disposed on the front side of the frame structure 10 for displaying images. The frame structure 10 includes a first end frame 11, a main frame 12, a second end frame 13, a first connector 14, and a second connector 15. The main frame 12 is located between the first end frame 11 and the second end frame 13. Since the first end frame 11, the main frame 12, and the second end frame 13 are separate structures, they are easy for users to assemble, thereby forming an integral frame structure. This facilitates the installation of other components of the LED display cabinet onto the frame structure 10. The first connector 14 is used to connect the main frame 11, the main frame 12, and the second end frame 13. The main frame 12 and the first end frame 11 are connected by a second connector 15. The first connector 14 and the second connector 15 ensure a stable connection between the first end frame 11, the main frame 12, and the second end frame 13, thus guaranteeing the overall structural strength of the frame structure 10. Users can adjust the overall length of the frame structure 10 by setting different lengths of the main frame 12 between the first end frame 11 and the second end frame 13. This allows the frame structure 10 to accommodate LED light panels of different sizes and quantities, enhancing its versatility and broadening its applicability. Therefore, the technical solution of this embodiment effectively solves the problem of poor versatility in related technologies.

[0028] like Figures 1 to 5 As shown, a first positioning structure 111 is provided on the first end frame 11, and a second positioning structure 121 is provided on the main frame 12 to cooperate with the first positioning structure 111. Specifically, the provision of the first positioning structure 111 and the second positioning structure 121 makes it more convenient, accurate and quick for users to assemble the first end frame 11 and the main frame 12. A similar positioning structure is also provided between the second end frame 13 and the main frame 12.

[0029] like Figures 1 to 5As shown, one of the first positioning structure 111 and the second positioning structure 121 includes a positioning insert 112, and the other of the first positioning structure 111 and the second positioning structure 121 includes a positioning slot 122 that engages with the positioning insert 112. Specifically, in this embodiment, the first positioning structure 111 includes the positioning insert 112, and the second positioning structure 121 includes the positioning slot 122. The positioning insert 112 and the positioning slot 122 have the advantages of simple structure and easy processing.

[0030] like Figures 1 to 5 As shown, the main frame 12 includes a first profile beam 123 extending along the direction from the first end frame 11 to the second end frame 13. A positioning slot 122 is formed at the end of the cavity of the first profile beam 123, and a positioning block 112 is disposed on the first end frame 11. In this embodiment, the main frame 12 is formed by cutting and splicing profiles, while the first end frame 11 and the second end frame 13 are formed by die casting. Since the main frame 12 is formed by profiles, the length of the main frame 12 can be changed more easily, and the cost is lower than that of die casting. The first end frame 11 and the second end frame 13 can be reused repeatedly. The positioning slot 122 is formed at the end of the cavity of the first profile beam 123, which also means that the positioning slot 122 does not need to be formed by other additional processing techniques.

[0031] like Figures 1 to 5 As shown, the first profile beam 123 is provided with a first connecting hole 1231, and the positioning block 112 is provided with a second connecting hole 1121. A first connecting member 14 passes through the first connecting hole 1231 and the second connecting hole 1121. Specifically, the first connecting member 14 is a fastening bolt, and there are multiple first connecting holes 1231 and second connecting holes 1121, which are arranged in a one-to-one correspondence. Multiple first connecting members 14 make the connection between the first profile beam 123 and the first end frame 11 more stable. Furthermore, the second connecting member 15 has a similar structure to the first connecting member 14.

[0032] like Figures 1 to 5 As shown, the main frame 12 includes a top profile beam 1232, a bottom profile beam 1233, and a second profile beam 124. The top profile beam 1232 and the bottom profile beam 1233 extend along the direction from the first end frame 11 to the second end frame 13. One end of the second profile beam 124 is connected to the top profile beam 1232, and the other end of the second profile beam 124 is connected to the bottom profile beam 1233. Specifically, the top profile beam 1232 and the bottom profile beam 1233 are both first profile beams 123, and the second profile beam 124 serves as a reinforcing beam, connecting the top profile beam 1232 and the bottom profile beam 1233 to enhance the overall structural strength of the main frame 12, thereby improving the reliability of the frame structure 10.

[0033] like Figures 1 to 5 As shown, the main frame 12 also includes a transition piece 125, a third connector 126, and a fourth connector 127. The third connector 126 is used to connect the transition piece 125 to the top profile beam 1232, and the fourth connector 127 is used to connect the transition piece 125 to the second profile beam 124. Specifically, the transition piece 125 enables the top profile beam 1232 and the second profile beam 124 to be connected. There are multiple transition pieces 125, with transition pieces 125 provided on both sides of the second profile beam 124 to make the connection more stable. A similar transition structure to the transition piece 125 is also provided between the bottom profile beam 1233 and the second profile beam 124.

[0034] like Figures 1 to 5 As shown, the adapter 125 includes a first plate 1251 and a second plate 1252 arranged at an angle. The first plate 1251 is fitted to the outer surface of the top profile beam 1232. A third connector 126 passes through the first plate 1251 and the top profile beam 1232. The second plate 1252 is fitted to the outer surface of the second profile beam 124. A fourth connector 127 passes through the second plate 1252 and the second profile beam 124. Specifically, the arrangement of the first plate 1251 and the second plate 1252 makes the structure of the adapter 125 relatively simple and allows it to fit the top profile beam 1232 and the second profile beam 124 respectively. The third connector 126 and the fourth connector 127 are both fastening bolts, and there are multiple bolts in total.

[0035] like Figures 1 to 5 As shown, in this embodiment, the LED display cabinet also includes a back cover. The inner side of the frame structure 10 is provided with a positioning protrusion 16, which engages with a stop on the back cover. The positioning protrusion 16 allows for quick positioning of the back cover, enabling rapid installation. The frame structure 10 has a latch 17, and the back cover has a latch that engages with the latch 17. The engagement between the latch 17 and the latch allows for quick installation and removal of the back cover.

[0036] This application also provides an LED display device, which includes multiple LED display cabinets spliced ​​together, wherein the LED display cabinet is the aforementioned LED display cabinet. The aforementioned LED display cabinet effectively solves the problem of poor versatility of frames in related technologies, and the LED display device with the aforementioned LED display cabinet also has the aforementioned advantages.

[0037] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0038] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0039] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
