Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Reference Figures 1 to 24 In one embodiment of the present invention, the frame assembly 10 includes a storage beam 1, a first connector 2, and a first column 3. The storage beam 1 has a first splicing hole 1153 in the vertical direction, so as to be connected to another frame assembly 10 by fasteners through a first docking member 61. The first connector 2 is disposed on one side of the storage beam 1. The first column 3 is connected to one side of the first connector 2 and forms a side that can be spliced ​​obliquely with the storage beam 1 and the first connector 2.

[0062] The rack assembly 10 is used to provide support for the carrier board 71 of the LED display device 100 and the control module, etc. It is sufficient as long as the rack assembly 10 can provide support and splicing function.

[0063] Since it is a diagonal splicing, the fasteners are used to connect the frame assembly 10 in the vertical direction. There is no specific limitation on the specific parts. It is also possible to drill holes and connect them in the vertical direction of the first connector 2 or the first column 3, or to fasten them in other directions such as in the horizontal direction. As long as the frame assembly 10 of this utility model is used for splicing, it falls within the protection scope of this utility model.

[0064] The obliquely spliced ​​side refers to the side structure jointly formed by the first column 3, the storage beam 1 and the first 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 obliquely splicing with other rack assemblies 10.

[0065] The first connector 2 is installed on one side of the receiving beam 1 and is tightly connected to the receiving beam 1. Its mechanical properties and structural design ensure the strength and stability of the joint. The fasteners mentioned here and thereafter can be bolts, which will not be elaborated further.

[0066] The structure of the first 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.

[0067] In this invention, two adjacent rack components 10 are aligned side-by-side for diagonal splicing, and connected to the first mating member 61 by fasteners passing through them vertically, thus completing the diagonal splicing of multiple rack components 10. Compared to horizontal splicing, diagonal splicing allows for the switching of display orientations of multiple LED display devices 100, enabling users to view the display from multiple angles and improving the viewing experience.

[0068] For example, Figure 1 The two LED display devices 100 can rotate 90°, allowing users to view the screen simultaneously from 0° and 90°. Furthermore, rotating and splicing the LED display devices 100 optimizes spatial layout, maximizing the use of horizontal and vertical dimensions within a limited space, thereby further increasing the display area.

[0069] 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 that is spaced apart from the first splicing hole 1153. The first positioning member 1151 is used to pass through the first alignment hole 613 of the first docking member 61.

[0070] Among them, the first positioning element 1151 and the various positioning elements mentioned below can be positioning pins, with the protruding part of the positioning pin serving as the positioning element.

[0071] 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 through 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, thus ensuring the consistency of the splicing position of two adjacent frame components 10, avoiding the misalignment of the LED, and thus ensuring the display effect of the LED display device 100.

[0072] 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 through the length direction of the receiving beam 1, so as to be connected to the other frame assembly 10 by fasteners through the second docking member 62.

[0073] The second docking member 62 includes two bent and connected plates, each plate having a second docking hole 621 through it, and each plate is attached to the surface of the column of the two adjacent frame assemblies 10 to fasten the two adjacent obliquely spliced ​​frame assemblies 10.

[0074] 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, and fasteners are sequentially inserted through the second splicing holes 31 and the docking holes 621 of the second docking member 62 to complete the splicing of the column parts 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.

[0075] Reference Figure 14 In one embodiment of this utility model, there are multiple storage beams 1, first connectors 2 and first columns 3, and each storage beam 1 and each first column 3 is provided with a first connector 2 at the connection point to form a frame structure.

[0076] In this embodiment, the rack assembly 10 is configured as a frame structure, and carrier plates 71 can be fixedly installed on the four periphery of the frame structure to support large areas or multiple carrier plates 71, so as to further meet the needs of large-area LED displays.

[0077] Optionally, refer to Figure 25 Since both sides of the rack assembly 10 are designed for diagonal splicing, by controlling the tilt angle of the sides, each LED display device 100 can be spliced ​​in an arc at any tilt angle, thus reducing the display dead angle and allowing users to see the LED display screen from all angles, further improving the user experience.

[0078] 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 length direction of the storage beam 1, and a first connecting part 21 is protruding on one side of the first connector 2, and the first connecting part 21 is inserted into the first mounting groove 111.

[0079] In this embodiment, inserting the first connecting part 21 of the first connector 2 into the first mounting groove 111 of the storage beam 1 can achieve quick positioning and installation of the connector on the storage beam 1, and reduce the volume of the frame assembly 10.

[0080] Optionally, after the first connecting part 21 is inserted into the first mounting groove 111, a fastener is used to pass through the first connecting hole 211 and the first mounting hole 1171, thereby achieving a tight connection between the first connecting member 2 and the first beam body 11 of the receiving beam 1. In addition, a first guide groove 1113 for guiding the first connecting member 2 is recessed in the side wall of the first mounting groove 111, and a third positioning member 1111 is provided in the bottom wall of the first mounting groove 111 for the third positioning hole 213 of the first connecting part 21 to be inserted, thereby facilitating the rapid assembly of the first connecting member 2 and improving structural stability.

[0081] Reference Figure 16 and Figure 7 In one embodiment of the present invention, a second connecting part 22 is also provided on one side of the first connecting member 2. The second connecting part 22 and the first connecting part 21 are spaced apart and are fastened to the storage beam 1 perpendicular to the length direction of the storage beam 1.

[0082] In this embodiment, after the first connector 2 is inserted into the first mounting slot 111, it is vertically fastened to the storage beam 1 through the second connecting part 22, for example, by using bolts to pass through the second connecting hole 221 of the second connecting part 22 and the second mounting hole 1172 of the storage beam 1. Therefore, the connection strength between the first connector 2 and the storage beam 1 is further strengthened, restricting the movement of the first connector 2 from multiple directions, making the frame assembly 10 less prone to damage when subjected to lateral forces.

[0083] Optionally, the first connector 2 can be further fastened to the receiving beam 1 by fasteners passing through the second connecting hole 221 and the second mounting hole 1172.

[0084] Reference Figure 16 and Figure 17 In one embodiment of the present invention, the first column 3 is provided with a first insertion hole 33 in the vertical direction, and one end of the first connector 2 is inserted into the first insertion hole 33.

[0085] In this embodiment, one end of the first connector 2 is aligned with the insertion hole of the first column 3 and inserted to achieve a preliminary splicing combination of the two. This insertion method allows for rapid assembly without the need for complex positioning and adjustment.

[0086] Optionally, the first connector 2 is fastened to the first column 3 by means of a fastener passing through a fifth mounting hole 371 formed on the side wall of the third connecting hole 231 and the first insertion hole 33, and a sixth mounting hole 372 formed on the other side wall of the fourth connecting hole 233 and the first insertion hole 33. Furthermore, a fifth connecting hole 251 is also provided on the inclined surface of the first connector 2, which is used for connecting the inclined end cap 19.

[0087] Reference Figure 16 and Figure 17 In one embodiment of the present invention, a first positioning hole 331 is provided on the side wall of the first insertion hole 33, and a first positioning part 23 is also provided on one side of the first connector 2, and the first positioning part 23 is inserted into the first positioning hole 331.

[0088] In this embodiment, the first positioning part 23 is aligned with the first positioning hole 231 and inserted, so that the connector can be accurately positioned after being inserted into the insertion hole of the column, preventing the first connector 2 from loosening or rotating in the first column 3, and ensuring the stability of the connection structure.

[0089] Reference Figure 3 and Figure 8 In one embodiment of the present invention, the rack assembly 10 further includes a second connector 4 and a second column 5. The second connector 4 is disposed on the other side of the storage beam 1 and has a third splicing hole 41 extending through the length of the storage beam 1, so as to be connected to another rack assembly 10 by fasteners.

[0090] The second column 5 is connected to one side of the second connector 4, and together with the storage beam 1 and the second connector 4, they form a side that can be horizontally spliced.

[0091] The side of the horizontal splicing refers to the side structure composed of the column, the storage beam 1 and the second connector 4. 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.

[0092] The second connector 4 is installed on the other 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 splice.

[0093] The structure of the second column 5 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.

[0094] In this embodiment, one side of the rack assembly 10 is designed to be angled for splicing, while the other side is designed to be horizontally spliced. This allows the same LED display device 100 to simultaneously meet the requirements of both horizontal and angled splicing, which is beneficial for meeting the needs of complex splicing scenarios.

[0095] During the horizontal splicing process, the sides of two adjacent rack components 10 are aligned for horizontal splicing. Fasteners are then passed through the third splicing holes 41 of the two adjacent second connectors 4 and locked in place, thereby completing the horizontal splicing of multiple rack components 10. It is worth noting that when the rack components 10 are spliced ​​horizontally, there are no left and right borders. Seamless left and right splicing can be achieved by directly connecting them with fasteners.

[0096] Reference Figure 3 , Figure 6 and Figure 8In one embodiment of this utility model, the receiving beam 1 has a fourth splicing hole 1163 along the vertical direction, and the fourth splicing hole 1163 and the third mating hole of the third mating member are used for fasteners to pass through. And / or, the second column 5 has a fifth splicing hole 56 perpendicular to the length direction of the receiving beam 1, and the fifth splicing hole 56 and the fourth mating hole 641 of the fourth mating member 64 are used for fasteners to pass through.

[0097] In this embodiment, by fastening two adjacent horizontally spliced ​​receiving beams 1 to the third docking member, the connection strength of two adjacent rack assemblies 10 can be strengthened. In addition, by connecting two adjacent horizontally spliced ​​second columns 5 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.

[0098] Optionally, the receiving beam 1 also has a second positioning member 1161 that is spaced apart from the fourth splicing hole 1163, for positioning and installing the third docking member. The second connecting member 4 also has an eleventh connecting hole 48 for connecting two adjacent rack assemblies 10 by fastening them together with the docking member.

[0099] Reference Figure 8 In one embodiment of this utility model, the second connector 4 is further provided with a protruding mating portion 421 spaced apart from the third splicing hole 41. And / or, the second connector 4 is further provided with a recessed mating groove 423 spaced apart from the third splicing hole 41.

[0100] In this embodiment, when two rack components 10 are horizontally spliced, the docking part 421 can dock with the docking groove 423 of the adjacent rack component 10; for cases where the docking groove 423 is recessed, during splicing, the docking part 421 of the adjacent rack component 10 can be embedded in the docking groove 423, thereby achieving precise positioning and splicing of the two adjacent rack components 10, preventing misalignment or shaking during splicing, and ensuring uniform display effect.

[0101] Reference Figure 8 In one embodiment of this utility model, the second connector 4 is further provided with a wire through hole 425 spaced apart from the third splicing hole 41. And / or, there are multiple third splicing holes 41, spaced apart from each other.

[0102] In this embodiment, when the two rack assemblies 10 are spliced ​​together by fasteners through the third splicing hole 41, the power supply line 741, signal line and other lines connecting the two rack assemblies 10 are passed through the wire hole 425, 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.

[0103] In addition, by setting multiple third splicing holes 41 for fastening connection, the connection strength of adjacent two rack components 10 can be enhanced, thereby ensuring the structural stability of the LED display device 100.

[0104] 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 length direction of the storage beam 1, and a third connecting part 451 is protruding on one side of the second connector 4, and the third connecting part 451 is inserted into the second mounting groove 113.

[0105] In this embodiment, inserting the third connecting part 451 of the second connector 4 into the second mounting groove 113 of the storage beam 1 can achieve quick positioning and installation of the second connector 4 on the storage beam 1, and reduce the volume of the rack assembly 10.

[0106] Optionally, after the third connecting part 451 is inserted into the second mounting groove 113, a fastener is used to pass through the sixth connecting hole 4513 and the third mounting hole 1173, thereby achieving a tight connection between the second connecting member 4 and the first beam body 11 of the receiving beam 1. In addition, a second guide groove 1133 for guiding the connecting member is recessed in the side wall of the second mounting groove 113, and a fourth positioning member 1131 is provided in the pin hole in the bottom wall of the second mounting groove 113 for insertion into the fourth positioning hole 4511 of the third connecting part 451, thereby facilitating the rapid assembly of the first connecting member 2 and improving structural stability.

[0107] Reference Figures 19 to 20 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 second mounting groove 113, and a fourth connecting part 453 is protruding on one side of the second connector 4. The fourth connecting part 453 is connected to the second beam body 13.

[0108] In this embodiment, by setting the first beam 11 and the second beam 13 and connecting them to the two connecting parts of the second connector 4 respectively, the connection strength between the second connector 4 and the receiving beam 1 is further strengthened, and the stability and deformation resistance of the entire frame assembly 10 are improved.

[0109] Optionally, the fourth connecting part 453 is fastened to the receiving beam 1 by passing a fastener through the seventh connecting hole 4531 and the fourth mounting hole 1174 of the second beam 13.

[0110] Optionally, refer to Figure 12 and Figure 13The end face of the second beam 13 is used to install circuit components such as the power supply 741.

[0125] 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.

[0126] The substrate 71 can be penetrated by an array of light-transmitting holes 713. LED beads 72 are arranged between the solid areas of each light-transmitting hole 713. By adjusting the brightness and color of each LED bead, the image can be displayed.

[0127] Reference Figure 3 , Figure 8 as well as Figure 9 In one embodiment of this utility model, the LED display device 100 further includes a pressing member 75. The pressing member 75 includes a fixed part 751 and a covering part 753 that are bent and connected. The fixed part 751 is connected to one side of the second column 5 so that the covering part 753 presses against the side of the carrier plate 71 away from the second column 5. The pressing member 75 is provided with a first clearance hole 7531 through the thickness direction to avoid the LED lamp bead 72. The connection between the fixed part 751 and the covering part 753 is also provided with a second clearance hole 755 through the connection to avoid the splicing flange 711 of the carrier plate 71.

[0128] In this embodiment, the pressing part 753 of the edge pressing member 75 presses against the carrier plate 71, preventing the edge of the carrier plate 71 from warping and ensuring the display effect of the LED. It is worth noting that the second clearance hole 755 avoids the splicing flange 711 of the carrier plate 71, allowing the carrier plates 71 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.

[0129] Optionally, refer to Figure 8 and Figure 15The fixing part 751 of the pressing part 75 has a fixing hole 7511, which is fastened to the tenth connecting hole 461 of the first groove 46 of the second connecting part 4 and the second groove 515 of the first plate 51 of the second column 5.
