[0026] An LED (Light Emitting Diode) display is a display device composed of LEDs. By controlling the brightness and color combination of the LEDs, it can present text, images, videos and other content. It has been widely used in areas such as commercial windows.

[0027] In the related art, in order to realize a large-area LED display, it is necessary to splice the rack components of multiple LED display devices. Therefore, how to effectively splice multiple rack components has become a research focus of researchers in this field.

[0028] In order to solve the above problems, the present invention proposes a rack assembly 10, which aims to achieve effective splicing of multiple rack assemblies 10, thereby realizing large-area display of LEDs.

[0029] Reference Figures 1 to 24 In one embodiment of the present invention, the rack assembly 10 includes a storage beam 1, a first connecting member 2 and a first column 3. The storage beam 1 is provided with a first splicing hole 1153 in the vertical direction, so as to be connected to the first docking member 61 with another rack assembly 10 through fasteners; the first connecting member 2 is provided on one side of the storage beam 1; the first column 3 is connected to one side of the first connecting member 2, and forms a side surface that can be spliced ​​obliquely with the storage beam 1 and the first connecting member 2.

[0030] The rack assembly 10 is used to provide support for the carrier board 71 and the control module of the LED display device 100 . It is sufficient as long as the rack assembly 10 can provide support and splicing functions.

[0031] Since it is an oblique splicing, the rack assembly 10 is connected by fasteners in the vertical direction. There is no specific limitation on the specific components. It can also be connected by punching holes in the vertical direction of the first connecting member 2 or the first column 3, or fastening and docking in other directions such as horizontally. As long as the structure of the rack assembly 10 of the present invention is used for splicing, it falls within the scope of protection of the present invention.

[0032] The obliquely spliced ​​side refers to the side structure composed of the first column 3, the storage beam 1 and the first connecting member 2. It can be the side of one component or multiple components used for splicing contact, as long as the rack assembly 10 has the function of oblique splicing with other rack assemblies 10.

[0033] The first connecting member 2 is installed on one side of the storage beam 1 and is tightly connected to the storage beam 1. Its own mechanical properties and structural design ensure the strength and stability of the splicing. The fasteners mentioned here and below can be bolts, which will not be described in detail later.

[0034] There is no specific limitation on the structure of the first column 3. As long as it can play a role in vertically supporting the storage beam 1, such as a hanging rope, it also falls within the protection scope of this application.

[0035] In the technical solution of the present invention, the sides of two adjacent rack assemblies 10 for diagonal splicing are aligned, and the two rack assemblies 10 are connected to the first docking member 61 by fasteners running vertically through the frame, thereby completing the diagonal splicing of multiple rack assemblies 10. Compared to horizontal splicing, diagonal splicing can achieve the reversible display of multiple LED display devices 100, allowing users to view the display from multiple angles, which is conducive to improving the viewing experience.

[0036] For example, Figure 1 Two LED display devices 100 can achieve 90° rotational display, allowing users to view the display from both 0° and 90° directions simultaneously. In addition, rotating and splicing the LED display devices 100 can optimize the spatial layout, making the best use of the horizontal and vertical dimensions within a limited space, thereby further increasing the display area.

[0037] Reference Figure 2 and Figure 12 In one embodiment of the present invention, the storage beam 1 is further provided with a first positioning member 1151 spaced apart from the first splicing hole 1153 , and the first positioning member 1151 is used to pass through the first alignment hole 613 of the first docking member 61 .

[0038] The first positioning member 1151 and the positioning members mentioned below may be positioning pins, and the protruding portion of the positioning pins serves as the positioning member.

[0039] In this embodiment, in order to facilitate the alignment of the first docking member 61 on the storage beam 1, the first positioning member 1151 is inserted into the first alignment hole 613 of the first docking member 61, thereby achieving the alignment of the first docking member 61 on two adjacent storage beams 1, thereby ensuring the consistency of the splicing positions of the two adjacent rack assemblies 10, avoiding the deviation of the LED, and then ensuring the display effect of the LED display device 100.

[0040] Reference Figure 5 and Figure 13 In one embodiment of the present invention, the first column 3 is provided with a second splicing hole 31 along the length direction of the storage beam 1, so as to be connected to the second docking member 62 with another rack component 10 through fasteners.

[0041] The second docking member 62 includes two bent plates connected to each other. The two plates are respectively penetrated by second docking holes 621 and respectively adhere to the column surfaces of two adjacent rack assemblies 10 to fasten the two adjacent obliquely spliced ​​rack assemblies 10.

[0042] In this embodiment, the second splicing holes 31 of the two rack assemblies 10 are aligned with the two second docking holes 621 of the second docking member 62. Fasteners are then inserted through the second splicing holes 31 and the docking holes 621 of the second docking member 62, completing the splicing of the column portions of the two rack assemblies 10. Therefore, the provision of the second splicing holes 31 increases the number of splicing connection points, allowing the rack assemblies 10 to be spliced ​​in different directions or positions, meeting the needs of complex splicing scenarios.

[0043] Reference Figure 14 In one embodiment of the present invention, the number of the storage beam 1, the first connecting member 2 and the first column 3 is respectively provided in plurality, and a first connecting member 2 is provided at the connection between each storage beam 1 and each first column 3 to enclose and form a frame structure.

[0044] In this embodiment, the rack assembly 10 is configured as a frame structure, and carrier plates 71 can be fixedly set on the four peripheries of the frame structure, which can support large areas or multiple carrier plates 71 to further meet the needs of large-area LED displays.

[0045] Optionally, refer to Figure 25Since both sides of the rack assembly 10 are configured as sides for oblique splicing, by controlling the inclination angle of the side, the LED display devices 100 can be arc-joined at any inclination angle, thereby reducing the display blind spot, allowing users to fully see the LED display screen from various angles, further improving the user experience.

[0046] Reference Figure 16 and Figure 17 In one embodiment of the present invention, a first mounting groove 111 is recessed on one side of the storage beam 1 in the longitudinal direction, and a first connecting portion 21 is protruded on one side of the first connecting member 2, and the first connecting portion 21 is inserted into the first mounting groove 111.

[0047] In this embodiment, the first connecting portion 21 of the first connecting member 2 is inserted into the first installation groove 111 of the receiving beam 1 , so as to achieve rapid positioning and installation of the connecting member on the receiving beam 1 and reduce the volume of the rack assembly 10 .

[0048] Optionally, after the first connecting portion 21 is inserted into the first mounting groove 111, a fastener is inserted through the first connecting hole 211 and the first mounting hole 1171, thereby achieving a secure connection between the first connecting member 2 and the first beam body 11 of the storage beam 1. In addition, a first guide groove 1113 is recessed in the side wall of the first mounting groove 111 for guiding the first connecting member 2, and a third positioning member 1111 is provided on the bottom wall of the first mounting groove 111 for receiving the third positioning hole 213 of the first connecting portion 21, thereby facilitating rapid assembly of the first connecting member 2 and improving structural stability.

[0049] Reference Figure 16 and Figure 7 In one embodiment of the present invention, a second connecting portion 22 is protruded from one side of the first connecting member 2. The second connecting portion 22 is spaced apart from the first connecting portion 21 and is fastened to the storing beam 1 perpendicular to the length direction of the storing beam 1.

[0050] In this embodiment, after the first connector 2 is inserted into the first mounting slot 111, it is vertically secured to the storage beam 1 via the second connector 22, for example, by bolts passing through the second connection hole 221 of the second connector 22 and the second mounting hole 1172 of the storage beam 1. This further strengthens the connection between the first connector 2 and the storage beam 1, restricting movement of the first connector 2 in multiple directions and making the rack assembly 10 less susceptible to damage when subjected to lateral forces.

[0051] Optionally, the second connection hole 221 and the second mounting hole 1172 are penetrated by a fastener, so as to further fasten the first connection member 2 to the storage beam 1 .

[0052] Reference Figure 16and Figure 17 In one embodiment of the present invention, the first column 3 is provided with a first plug hole 33 along the vertical direction, and one end of the first connecting member 2 is inserted into the first plug hole 33.

[0053] In this embodiment, one end of the first connector 2 is aligned with the plug-in hole of the first column 3 and inserted to achieve a preliminary splicing combination of the two. This plug-in method assembles quickly and does not require complicated positioning and adjustment.

[0054] Optionally, the first connector 2 is fastened to the first column 3 by passing a fastener through the third connecting hole 231 and a fifth mounting hole 371 defined in a side wall of the first insertion hole 33, and by passing a fastener through the fourth connecting hole 233 and a sixth mounting hole 372 defined in another side wall of the first insertion hole 33. Furthermore, a fifth connecting hole 251 is defined on the inclined surface of the first connector 2 for connection to the inclined surface end cap 19.

[0055] Reference Figure 16 and Figure 17 In one embodiment of the present invention, a first positioning hole 331 is defined on the side wall of the first plug hole 33 , and a first positioning portion 23 is protruded from one side of the first connector 2 , and the first positioning portion 23 is inserted into the first positioning hole 331 .

[0056] In this embodiment, the first positioning portion 23 is aligned with the first positioning hole 231 and inserted so that the connector can be accurately positioned after being inserted into the plug hole of the column, thereby preventing the first connector 2 from loosening or rotating in the first column 3 and ensuring the stability of the connection structure.

[0057] Reference Figure 3 and Figure 8 In one embodiment of the present invention, the rack assembly 10 further includes a second connecting member 4 and a second column 5. The second connecting member 4 is provided on the other side of the receiving beam 1 and is provided with a third splicing hole 41 extending along the length direction of the receiving beam 1 so as to be connected to another rack assembly 10 by fasteners. The second column 5 is connected to one side of the second connecting member 4 and forms a side surface that can be horizontally spliced ​​with the storage beam 1 and the second connecting member 4.

[0058] Among them, the side surface for horizontal splicing refers to the side structure jointly formed by the column, the storage beam 1 and the second connecting member 4, which can be the side surface of one component or multiple components for splicing contact, as long as the rack assembly 10 has the function of horizontal splicing with other rack assemblies 10.

[0059] The second connecting member 4 is installed on the other side of the storage beam 1 and is tightly connected to the storage beam 1. Its own mechanical properties and structural design ensure the strength and stability of the splicing.

[0060] There is no specific limitation on the structure of the second column 5. As long as it can play the role of vertically supporting the storage beam 1, such as a hanging rope, it also falls within the protection scope of this application.

[0061] In this embodiment, one side of the rack assembly 10 has a side that can be spliced ​​diagonally, and the other side is set as a side that can be spliced ​​horizontally, so that the same LED display device 100 can meet the performance of both horizontal splicing and diagonal splicing, which is conducive to meeting the needs of complex splicing scenarios.

[0062] During the horizontal splicing operation, the sides of two adjacent rack assemblies 10 for horizontal splicing are aligned, and fasteners are passed through the third splicing holes 41 of the two adjacent second connectors 4 and tightened, thereby completing the horizontal splicing of multiple rack assemblies 10. It is worth noting that when the rack assemblies 10 are horizontally spliced, there are no left or right borders, and the fasteners are directly inserted and connected to achieve seamless left and right splicing.

[0063] Reference Figure 3 、 Figure 6 and Figure 8 In one embodiment of the present invention, the storage beam 1 has a fourth splicing hole 1163 vertically defined therein. This fourth splicing hole 1163 and the third docking hole of the third docking member are used to receive fasteners. Alternatively, the second column 5 has a fifth splicing hole 56 perpendicular to the length of the storage beam 1. This fifth splicing hole 56 and the fourth docking hole 641 of the fourth docking member 64 are used to receive fasteners.

[0064] In this embodiment, by fastening two adjacent transversely spliced ​​storage beams 1 to the third docking member, the connection strength of the two adjacent rack assemblies 10 can be strengthened. In addition, by connecting two adjacent transversely spliced ​​second columns 5 to the second docking member 62, the connection strength of the two adjacent rack assemblies 10 can be further strengthened, thereby further ensuring the structural stability of the LED display device 100.

[0065] Optionally, the storage beam 1 is further provided with a second positioning member 1161 spaced apart from the fourth splicing hole 1163 for positioning and installing the third docking member. The second connecting member 4 is further provided with an eleventh connecting hole 48 for connecting two adjacent rack assemblies 10 by fastening with docking members.

[0066] Reference Figure 8 In one embodiment of the present invention, the second connecting member 4 further comprises a protruding docking portion 421 spaced apart from the third splicing hole 41 . And / or, the second connecting member 4 further comprises a concave docking groove 423 spaced apart from the third splicing hole 41 .

[0067] In this embodiment, when two rack assemblies 10 are horizontally spliced, the docking portion 421 can be docked with the docking groove 423 of the adjacent rack assembly 10; in the case where the docking groove 423 is recessed, when splicing, the docking portion 421 of the adjacent rack assembly 10 can be embedded in the docking groove 423, thereby achieving accurate positioning and splicing of the two adjacent rack assemblies 10, preventing dislocation or shaking during the splicing process, and ensuring uniform display effects.

[0068] Reference Figure 8 In one embodiment of the present invention, the second connecting member 4 is further provided with a wire hole 425 spaced apart from the third splicing hole 41. And / or, the number of the third splicing holes 41 is multiple, and the multiple third splicing holes 41 are spaced apart.

[0069] In this embodiment, when the two rack assemblies 10 are spliced ​​together by fasteners passing through the third splicing holes 41, the power supply 741 lines, signal lines, and other lines connecting the two rack assemblies 10 are passed through the wire holes 425, thereby achieving electrical connection between the two rack assemblies 10, ensuring that the LED display device 100 can operate normally, such as displaying images, receiving control signals, etc.

[0070] In addition, by providing a plurality of third splicing holes 41 for fastening connection, the connection strength between two adjacent rack assemblies 10 can be enhanced, thereby ensuring the structural stability of the LED display device 100.

[0071] Reference Figure 19 and Figure 20 In one embodiment of the present invention, a second mounting groove 113 is recessed on the other side of the storage beam 1 in the longitudinal direction, and a third connecting portion 451 is protruded on one side of the second connecting member 4, and the third connecting portion 451 is inserted into the second mounting groove 113.

[0072] In this embodiment, the third connecting portion 451 of the second connecting member 4 is inserted into the second installation groove 113 of the storage beam 1, so as to realize the rapid positioning and installation of the second connecting member 4 on the storage beam 1 and reduce the volume of the rack assembly 10.

[0073] Optionally, after the third connecting portion 451 is inserted into the second mounting slot 113, a fastener is provided through the sixth connecting hole 4513 and the third mounting hole 1173, thereby achieving a secure connection between the second connecting member 4 and the first beam body 11 of the storage beam 1. Furthermore, a second guide groove 1133 is recessed in the sidewall of the second mounting slot 113 for guiding the connecting member, and a fourth positioning member 1131 is provided in the latch hole of the bottom wall of the second mounting slot 113 for insertion into the fourth positioning hole 4511 of the third connecting portion 451, thereby facilitating rapid assembly of the first connecting member 2 and improving structural stability.
