[0028] LED (Light Emitting Diode) displays are display devices made of LEDs. By controlling the brightness and color combination of LEDs, they can display text, images, videos, and other content, and are widely used in commercial window displays and other fields.

[0029] In related technologies, to achieve large-area LED displays, it is necessary to splice together rack assemblies of multiple LED display devices. Therefore, how to effectively splice together multiple rack assemblies is a key research focus for those in this field.

[0030] To address the aforementioned issues, this invention proposes a rack assembly 10, which aims to achieve effective splicing of multiple rack assemblies 10, thereby enabling large-area LED display.

[0031] Reference Figures 1 to 15 In one embodiment of the present invention, the frame assembly 10 includes a storage beam 1, a connector 2, and a column 3. The connector 2 is disposed on one side of the storage beam 1 and has a first splicing hole 21 extending through the length of the storage beam 1, so as to be connected to another frame assembly 10 by fasteners. The column 3 is connected to one side of the connector 2 and forms a side that can be spliced ​​laterally with the storage beam 1 and the connector 2.

[0032] The rack assembly 10 is used to provide support for the carrier plate 41 of the LED display device 100 and the control module, etc. The specific structure of the rack assembly 10 is not limited here, as long as it can provide support and splicing function.

[0033] The side of the horizontal splicing refers to the side structure composed of the column 3, the storage beam 1 and the connector 2. It can be the side of one or more components used for splicing contact, as long as the rack assembly 10 has the function of horizontal splicing with other rack assemblies 10.

[0034] Connector 2 is installed on one side of the storage beam 1 and is tightly connected to the storage beam 1. Its mechanical properties and structural design ensure the strength and stability of the joint. The fasteners mentioned here and below can be bolts, which will not be elaborated further.

[0035] The structure of column 3 is not specifically limited. As long as it can provide vertical support for the storage beam 1, such as a hanging rope, it also falls within the protection scope of this application.

[0036] In the technical solution of this utility model, the sides of two adjacent rack components 10 are aligned for horizontal splicing. Fasteners are passed through the splicing holes of two adjacent connectors 2 and locked in place, thereby completing the horizontal splicing of multiple rack components 10. It is worth noting that the rack components 10 have no left or right borders, and the left and right seamless splicing can be achieved by directly connecting them with fasteners.

[0037] Reference Figure 4 In one embodiment of this utility model, the connector 2 is further provided with a protruding mating portion 221 spaced apart from the first splicing hole 21. And / or, the connector 2 is further provided with a recessed mating groove 223 spaced apart from the first splicing hole 21.

[0038] In this embodiment, when two rack components 10 are horizontally spliced, the docking part 221 can dock with the docking groove 223 of the adjacent rack component 10. When the docking groove 223 is recessed, the docking part 221 of the adjacent rack component 10 can be embedded in the docking groove 223 during splicing, thereby achieving precise positioning and splicing of the two adjacent rack components 10, preventing misalignment or shaking during splicing, and ensuring uniform display effect.

[0039] Reference Figure 4 In one embodiment of this utility model, the connector 2 is further provided with a wire through hole 225 spaced apart from the first splicing hole 21. And / or, there are multiple first splicing holes 21, which are spaced apart.

[0040] In this embodiment, when the two rack assemblies 10 are spliced ​​together through the first splicing hole 21 by fasteners, the power supply line 441, signal line and other lines connecting the two rack assemblies 10 are passed through the wire hole 225, thereby realizing the electrical connection between the two rack assemblies 10 and ensuring that the LED display device 100 can work normally, such as displaying images and receiving control signals.

[0041] In addition, by setting multiple splicing holes for fastening, the connection strength between adjacent rack components 10 can be enhanced, thereby ensuring the structural stability of the LED display device 100.

[0042] Reference Figure 3 and Figure 8 In one embodiment of this utility model, there are multiple storage beams 1, connectors 2 and columns 3, and each storage beam 1 and each column 3 is provided with a connector 2 at the connection point to form a frame structure.

[0043] In this embodiment, the rack assembly 10 is configured as a frame structure, and carrier plates 41 can be fixedly installed on the four periphery of the frame structure to support large areas or multiple carrier plates 41, so as to further meet the needs of large-area LED display.

[0044] Reference Figure 11 and Figure 12 In one embodiment of the present invention, a first mounting groove 111 is recessed on one side of the length direction of the storage beam 1, and a first connecting part 251 is protruding on one side of the connector 2, and the first connecting part 251 is inserted into the first mounting groove 111.

[0045] In this embodiment, inserting the first connecting part 251 of the connector 2 into the first mounting groove 111 of the storage beam 1 can achieve quick positioning and installation of the connector 2 on the storage beam 1, and reduce the volume of the rack assembly 10.

[0046] Optionally, after the first connecting part 251 is inserted into the first mounting groove 111, a fastener is used to pass through the first connecting hole 2513 and the first mounting hole 117, thereby achieving a tight connection between the connector 2 and the first beam body 11 of the receiving beam 1. In addition, a guide groove 1113 for guiding the connector 2 is recessed in the side wall of the first mounting groove 111, and a first positioning member 1111 is provided in the pin hole 118 on the bottom wall of the first mounting groove 111 for insertion into the second positioning hole 2511 of the first connecting part 251, thereby facilitating the rapid assembly of the connector 2 and improving the stability of the frame structure.

[0047] Reference Figure 11 and Figure 12 In one embodiment of the present invention, the receiving beam 1 is formed with a first beam body 11 and a second beam body 13 arranged vertically at intervals. The first beam body 11 is recessed with the first mounting groove 111, and the connector 2 is also provided with a second connecting part 253 protruding on one side. The second connecting part 253 is connected to the second beam body 13.

[0048] In this embodiment, by setting the first beam 11 and the second beam 13 and connecting them to the two connecting parts of the connector 2 respectively, the connection strength between the connector 2 and the receiving beam 1 is further strengthened, and the stability and deformation resistance of the entire frame assembly 10 are improved.

[0049] Optionally, a fastening connection between the connector 2 and the second beam body 13 of the receiving beam 1 is achieved by fasteners passing through the second connecting hole 2531 and the second mounting hole 131.

[0050] Optionally, refer to Figure 8The end face of the second beam 13 is used to install circuit components such as the power supply 441. The side wall of the first beam 11 of the housing beam 1 is provided with a snap-fit ​​hole 14. By directly pulling the handle 443, the limiting shaft 81 of the snap-fit ​​assembly 8 connected to the carrier plate 41 is passed through the snap-fit ​​hole 14 and rotated. Then, the limiting part 83 is snapped into the edge of the opening of the snap-fit ​​hole 14. This installation method is quick to operate and can expose the carrier plate 41 as much as possible, making the upper and lower bezels of the LED display device 100 very narrow, which is conducive to further increasing the display area of ​​the LED.

[0051] Reference Figure 11 and Figure 12 In one embodiment of the present invention, the connector 2 is recessed with a connecting groove 23 spaced apart from the first splicing hole 21, and the bottom wall of the connecting groove 23 is provided with a positioning part 231. The part of the column 3 connected to the connector 2 is provided with a first positioning hole 311, and the positioning part 231 is provided in the first positioning hole 311.

[0052] In this embodiment, inserting the positioning part 231 in the connecting groove 23 into the first positioning hole 311 of the column 3 can ensure the accurate connection between the column 3 and the connector 2, improve the assembly accuracy, avoid positional deviation, and thus effectively ensure the uniform distribution and accurate alignment of pixels, thereby improving the image display quality of the display screen.

[0053] Optionally, a fastening connection between the connector 2 and the first plate 31 of the column 3 is achieved by passing fasteners through the fourth connecting hole 233 and the third mounting hole 313.

[0054] Reference Figure 11 and Figure 12 In one embodiment of the present invention, the column 3 includes a first plate 31 and a second plate 33 that are bent and connected. The first plate 31 is provided with the first positioning hole 311 and is installed in the connecting groove 23. The bottom wall of the connecting groove 23 is provided with a clamping hole 235. The clamping hole 235 is provided with a third connecting part 255 protruding from the opening edge of the connecting groove 23. The second plate 33 passes through the clamping hole 235 and is connected to the third connecting part 255.

[0055] In this embodiment, the first plate 31 is installed in the connecting groove 23 via the positioning part 231, and the second plate 33 is partially inserted into the clamping hole 235 and connected to the third connecting part 255. This bent column 3 structure can increase the strength and rigidity of the column 3. At the same time, the connection between the column 3 and the connector 2 via the clamping hole 235 and the third connecting part 255 makes the connection between the column 3 and the connector 2 more secure and reliable, improving the load-bearing capacity and stability of the entire frame assembly 10. For some heavier LED display devices 100, this can effectively prevent the connection from loosening due to vibration or weight, and extend the service life of the LED display device 100.

[0056] Optionally, a fastening connection between the connector 2 and the second plate 33 of the column 3 is achieved by passing fasteners through the third connecting hole 2551 and the fourth mounting hole 331.

[0057] Reference Figure 7 and Figure 11 In one embodiment of the present invention, the column 3 further includes a wire guide 35, which is connected to the second plate 33 and forms a wire passage with the first plate 31 and the second plate 33.

[0058] In this embodiment, the formation of the wire passage can neatly store the wires inside and provide a connection between the upper and lower storage beams 1, avoiding exposed wires. This not only improves the aesthetics but also prevents the wires from being damaged by the outside world, while also facilitating heat dissipation and management of the wires.

[0059] Reference Figure 7 and Figure 8 In one embodiment of the present invention, the storage beam 1 is provided with a storage groove 18, and the frame assembly 10 further includes a cover shell 16. The cover shell 16 is rotatably connected to the side wall of the storage groove 18 via a screw cap shaft 163 to close or open the opening of the storage groove 18.

[0060] A bracket 161 can be connected to the side wall of the storage slot 18, and the cover 16 is connected to the bracket 161 through a screw-on shaft 163, thereby achieving a rotatable setting. In addition, since the cover 16 rotates in the direction of the shaft connection, compared with the traditional hinge connection, it is beneficial to further improve the aesthetics of the LED display device 100.

[0061] In this embodiment, the cover 16 protects the components inside the storage slot 18, preventing damage to the internal parts. Simultaneously, when maintenance or repair of the components inside the storage slot 18 is required, the cover 16 can be easily opened for operation.

[0062] Optionally, when the cover 16 completely closes the opening of the storage slot 18, the locking member 165 is sequentially inserted into the locking hole 17 of the cover 16 and the storage beam 1, thereby preventing the cover 16 from shaking and ensuring the normal operation of the LED display device 100.

[0063] Reference Figures 1 to 3 In one embodiment of this utility model, the receiving beam 1 has a second splicing hole 116 in the vertical direction, and the second splicing hole 116 and the first mating hole of the first mating member are used for fasteners to pass through. And / or, the column 3 has a third splicing hole 36 perpendicular to the length direction of the receiving beam 1, and the third splicing hole 36 and the second mating hole 621 of the second mating member 62 are used for fasteners to pass through.

[0064] In this embodiment, by fastening two adjacent receiving beams 1 to the first docking member, the connection strength of two adjacent rack assemblies 10 can be strengthened. In addition, by connecting two adjacent columns 3 to the second docking member 62, the connection strength of two adjacent rack assemblies 10 can be further strengthened, thereby further ensuring the structural stability of the LED display device 100.

[0065] Optionally, a second positioning member 115 is provided above or below the receiving beam 1. The second positioning member 115 is inserted into the alignment hole of the first docking member, thereby facilitating the rapid splicing of the first docking member. The connector 2 is also provided with a sixth connecting hole 28 for connecting two adjacent frame assemblies 10 by fastening them together with the docking member.

[0066] This utility model also proposes an LED display device 100, which includes a carrier plate 41 and a frame assembly 10 as described above. The carrier plate 41 is disposed on one side of the column 3, and LED beads 42 are disposed on the side away from the column 3.

[0067] The specific structure of the rack assembly 10 is as described in the above embodiments. Since the LED display device 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0068] The substrate 41 has an array of light-transmitting holes 413 through it. LED beads 42 are arranged between the solid areas of each light-transmitting hole 413. By adjusting the brightness and color of each LED bead, the image can be displayed.

[0069] Reference Figure 2 and Figure 5In one embodiment of this utility model, the LED display device 100 further includes a pressing member 43. The pressing member 43 includes a fixed part 431 and a covering part 433 that are bent and connected. The fixed part 431 is connected to one side of the column 3 so that the covering part 433 presses against the side of the carrier plate 41 away from the column 3. The pressing member 43 is provided with a first clearance hole 4331 through the thickness direction to avoid the LED lamp bead 42. A second clearance hole 435 is also provided through the connection between the fixed part 431 and the covering part 433 to avoid the splicing flange 411 of the carrier plate 41.

[0070] In this embodiment, the pressing part 433 of the edge pressing member 43 presses against the carrier plate 41, preventing the edge of the carrier plate 41 from warping and ensuring the display effect of the LED. It is worth noting that the second clearance hole 435 avoids the splicing flange 411 of the carrier plate 41, allowing the carrier plates 41 of two adjacent LED display devices 100 to be directly and seamlessly spliced, thereby reducing the display dead zone, further optimizing the display effect, and improving assembly efficiency.

[0071] Optionally, refer to Figure 8 and Figure 15 The fixing part 431 of the pressing part 43 has a fixing hole 4311, which is fastened to the second groove 315 of the first plate 31 and the fifth connecting hole 261 of the first groove 26 of the connector 2 respectively.

[0072] Reference Figure 1 and Figure 2 The present invention also proposes a display device 1000, which includes at least two LED display devices 100 as described above. Two adjacent LED display devices 100 are horizontally spliced ​​together and connected to the first splicing hole 21 of the two adjacent LED display devices 100 by fasteners.

[0073] The specific structure of the LED display device 100 is as described in the above embodiments. Since the display device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0074] Optionally, based on the splicing of multiple LED display devices 100, a hanging ring 15 is provided above the storage beam 1 to suspend the multiple LED display devices 100, thereby further optimizing the screen display and improving the user experience.

[0075] It is worth noting that when multiple LED display devices 100 are spliced ​​together, the support column 3 at the splicing point of two adjacent LED display devices 100 can be removed and replaced with a suspension rope, such as a steel wire rope. This suspension rope is then connected to the upper and lower connectors 2 or the storage beam 1, thereby providing vertical support to the upper and lower beams. This implementation method also falls within the protection scope of this utility model. Therefore, by eliminating the obstruction of the support column 3, the spliced ​​display device 1000 can be made more transparent and has a larger display area, thus further enhancing the user experience.

[0076] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
