Description

Technical Field

[0001] This invention relates to the field of display device technology, and in particular to an LED all-in-one machine. Background Technology

[0002] With the rapid development of the LED display industry, LED all-in-one machines are widely used in scenarios such as conferences, education, security, transportation, and cinemas. LED all-in-one machines are mainly available in wall-mounted, recessed, and mobile bracket installations, with wall-mounted and recessed installations each accounting for 40%-50%.

[0003] Currently, LED all-in-one machines typically have a control device on the back. When the control device malfunctions, it needs to be removed from the back of the LED all-in-one machine to maintain the faulty module. Therefore, embedded installation requires sufficient space for maintenance, which greatly affects the user experience and reduces product competitiveness.

[0004] Therefore, there is an urgent need for a solution that allows users to open and maintain the control device without compromising their customer experience, thereby improving maintenance efficiency and enhancing product competitiveness. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problem in related technologies where LED all-in-one machines are difficult to maintain from the back, which affects the user experience.

[0006] To solve the above-mentioned technical problems, the present invention provides an LED all-in-one machine, including an LED housing and a diagonal brace assembly disposed on the back of the LED housing. The top of the LED housing is used to connect to a mounting surface, and the diagonal brace assembly is disposed near the bottom of the LED housing. The diagonal brace assembly includes: The main arm has a connecting end and a free end at its two ends along its length. The connecting end of the main arm is rotatably connected to the mounting surface, and an accommodating opening is provided on the side wall of the main arm near the free end. An inner arm is movably disposed on the main arm along the length direction of the main arm, and the end of the inner arm away from the connecting end of the main arm is rotatably connected to the back of the LED housing; The card is rotatably mounted on the surface of the inner arm facing the main arm, and the side wall of the inner arm has an abutment corresponding to the position of the card; When an external force drives the bottom of the LED housing to move relative to the mounting surface, the inner arm moves relative to the main arm. The inner arm can move the card to the position of the receiving opening. The card can rotate in a set direction at the receiving opening so that the end of the card can engage with the edge of the receiving opening of the main arm, thereby supporting the main arm and the inner arm between the LED housing and the mounting surface.

[0007] In some embodiments of this application, the diagonal brace assembly further includes a limiting rib, the limiting rib protruding from the surface of the main arm facing the inner arm, and the limiting rib being disposed on the side of the receiving opening near the free end; An external force drives the bottom of the LED housing to move away from the mounting surface, and the inner arm moves relative to the main arm. When the limiting rib abuts against the card, the external force drives the bottom of the LED housing to move closer to the mounting surface. The limiting rib can drive the card to rotate, so that the card can rotate in a set direction at the receiving opening, so that the end of the card is engaged at the edge of the receiving opening of the main arm.

[0008] In some embodiments of this application, card interfaces are respectively provided at both ends of the card, and the card interfaces are V-shaped; when the inner arm is relative to the main arm and the limiting rib abuts against the card, one of the card interfaces of the card abuts against the limiting rib. When the bottom of the LED box is relatively close to the mounting surface, the limiting rib can release the card from the latch and drive the card to rotate, so that the card can rotate in a set direction at the receiving opening, so that the other card interface of the card is latched with the edge of the receiving opening of the main arm.

[0009] In some embodiments of this application, the diagonal brace assembly further includes a damping block movably disposed on the surface of the inner arm facing the main arm, with the end of the damping block disposed away from the inner arm and connected to the back of the LED housing.

[0010] In some embodiments of this application, the bracing assembly further includes a grommet screw, and the damping block is movably connected to the inner arm via the grommet screw.

[0011] In some embodiments of this application, the inner arm includes an inner plate and connecting plates disposed on both sides of the inner plate in the width direction. The connecting plate includes a connecting body and a raised edge. The connecting body is connected to the edge of the inner plate, and the raised edge is bent and connected to the side of the connecting body away from the inner plate. The inner plate and the connecting plates on both sides enclose each other to form a receiving groove, and the damping block is disposed in the receiving groove; one end of the inner plate is rotatably connected to the back of the LED box, and the damping block is disposed near the other end of the inner plate; the card is disposed near the damping block, and an avoidance opening is provided on one of the connecting bodies for the card to pass through.

[0012] In some embodiments of this application, the main arm includes a main board and extension plates disposed on both sides of the main board in the width direction. The extension plate includes a plate body and a stop. The plate body is connected to the edge of the main board, and the stop is bent and connected to the side of the plate body away from the main board. The end of the main board is rotatably connected to the mounting surface, wherein the receiving opening is provided on one of the plate bodies. The main board and the extension plates on both sides enclose each other to form a sliding groove, and the inner arm is movably disposed in the sliding groove.

[0013] In some embodiments of this application, the diagonal brace assembly further includes a connecting unit, the connecting unit including a connector and a fixing member disposed on the connector; the connector includes a connecting portion and an abutment portion and a transition portion respectively bent and connected to both sides of the connecting portion, and the fixing member passes through the transition portion; The main arm is provided with the connecting unit at the connecting end. The connecting unit on the main arm is the first connecting unit. The connecting end of the main arm is rotatably connected to the connecting part of the first connecting unit. The fixing part of the first connecting unit is used to fix it on the mounting surface. The abutting part of the first connecting unit is set towards the LED box. The inner arm is provided with the connecting unit at the end away from the connecting end of the main arm. The connecting unit on the inner arm is a second connecting unit. The end of the inner arm is rotatably connected to the connecting part of the second connecting unit. The fixing member of the second connecting unit is fixed to the back of the LED box. The abutting part of the second connecting unit is set towards the mounting surface.

[0014] In some embodiments of this application, the diagonal brace assembly further includes a buffer pad, and the buffer pad is provided on the surface of the abutting portion of the first connecting unit facing the LED housing and on the surface of the abutting portion of the second connecting unit facing the mounting surface.

[0015] In some embodiments of this application, the LED integrated machine includes multiple rows of LED housings spliced ​​together, and the diagonal bracing assembly is provided on the back of at least two of the LED housings.

[0016] As can be seen from the above technical solution, the beneficial effects of the present invention are as follows: For the LED integrated machine of the present invention, when an external force drives the bottom of the LED cabinet to move, the inner arm can slide along the main arm and drive the card into the receiving port. After the card rotates at the receiving port, it engages with the edge of the main arm, forming a mechanical lock. This setting can achieve rapid adjustment and fixation of the support angle of the LED cabinet without additional tools, which is especially suitable for scenarios that require frequent debugging or temporary installation, making it convenient for users to quickly and efficiently complete the back maintenance of the LED cabinet. Furthermore, the main arm, inner arm, and mounting surface can form a triangular support system, using the geometric stability of the triangle to resist the self-weight of the LED cabinet and external loads. This support system can convert vertical loads into axial pressure and transmit them to the mounting surface. At the same time, the engagement of the card enhances the rigidity of the nodes, ensuring the stability of the diagonal support of the LED cabinet.

[0017] In addition, the diagonal bracing component of this application is integrated into the back of the LED cabinet and set near the bottom, which neither occupies the front display area nor fails to effectively balance the suspension force on the top of the LED cabinet.

[0030] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0031] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and 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. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] See Figures 1 to 5One embodiment of this application provides an LED all-in-one machine 100, including an LED housing 10 and a diagonal brace assembly 20 disposed on the back of the LED housing 10. The top of the LED housing 10 is used to connect to a mounting surface 200, and the diagonal brace assembly 20 is disposed near the bottom of the LED housing 10. The mounting surface 200 can be any mounting surface such as a wall.

[0034] The diagonal bracing assembly 20 includes a main arm 21, an inner arm 22, and a clip 23. The main arm 21 has a connecting end 211 and a free end 212 at its two ends along its length. The connecting end 211 is rotatably connected to the mounting surface 200, and a receiving opening 213 is provided on the side wall of the main arm 21 near the free end 212. The inner arm 22 is movably mounted on the main arm 21 along its length, and the end of the inner arm 22 away from the connecting end 211 is rotatably connected to the back of the LED housing 10. The clip 23 is rotatably mounted on the surface of the inner arm 22 facing the main arm 21, and a clearance opening 221 is provided on the side wall of the inner arm 22 corresponding to the position of the clip 23.

[0035] When the bottom of the LED housing 10 moves relative to the mounting surface 200, the inner arm 22 moves relative to the main arm 21. The inner arm 22 can move the card 23 to the position of the receiving opening 213. The card 23 can rotate in a set direction at the receiving opening 213 so that the end of the card 23 can engage with the edge of the receiving opening 213 of the main arm 21, thereby supporting the main arm 21 and the inner arm 22 between the LED housing 10 and the mounting surface 200.

[0036] In this application, the LED integrated machine 100 also includes a control device 30, which is located on the back of the LED housing 10 and near the bottom of the LED housing 10. When the LED integrated machine 100 needs to be installed or repaired, such as when installing or repairing the control device 30 on the back of the LED housing 10, it can be supported between the LED housing 10 and the mounting surface 200 by the main arm 21 and inner arm 22 of the diagonal brace assembly 20. This allows the LED housing 10 and the mounting surface 200 to quickly and stably form an angled space, enabling operators to assemble and maintain the control device 30 through the space on the left and right sides and below the LED housing 10, thus improving the efficiency of installation and maintenance.

[0037] For the LED all-in-one machine 100 of this application, when an external force drives the bottom of the LED cabinet 10 to move, the inner arm 22 can slide along the main arm 21 and drive the card 23 into the receiving port 213. After the card 23 rotates at the receiving port 213, it engages with the edge of the main arm 21, forming a mechanical lock. This setting can achieve quick adjustment and fixation of the support angle of the LED cabinet 10 without additional tools, which is especially suitable for scenarios that require frequent debugging or temporary installation, making it convenient for users to quickly and efficiently complete the back maintenance of the LED cabinet 10. Furthermore, the main arm 21, the inner arm 22, and the mounting surface 200 can form a triangular support system, using the geometric stability of the triangle to resist the self-weight of the LED cabinet 10 and external loads. This support system can convert vertical loads into axial pressure and transmit them to the mounting surface 200. At the same time, the engaging action of the card 23 enhances the rigidity of the nodes, ensuring the stability of the diagonal support of the LED cabinet 10.

[0038] In addition, the diagonal bracing component 20 of this application is integrated into the back of the LED cabinet 10 and is set near the bottom, which neither occupies the front display area nor fails to effectively balance the suspension force on the top of the LED cabinet 10.

[0039] like Figures 6 to 8 As shown, in some embodiments of this application, the inner arm 22 includes an inner plate 222 and connecting plates 223 disposed on both sides of the inner plate 222 in the width direction. The connecting plate 223 includes a connecting body 2231 and a raised edge 2232. The connecting body 2231 is connected to the edge of the inner plate 222, and the raised edge 2232 is bent and connected to the side of the connecting body 2231 away from the inner plate 222. The inner plate 222 and the connecting plates 223 on both sides can be closed to form a receiving groove 224.

[0040] The main arm 21 includes a main board 214 and extension plates 215 disposed on both sides of the main board 214 in the width direction. The extension plates 215 include a main body and a flange 2152. The main body is connected to the edge of the main board 214, and the flange 2152 is bent and connected to the side of the main body away from the main board 214. The end of the main board 214 is rotatably connected to the mounting surface 200, and one of the main bodies has an accommodating opening 213.

[0041] In this embodiment, the main board 214 and the extension plates 215 on both sides form a sliding groove 216, and the inner arm 22 is movably disposed in the sliding groove 216. When the inner arm 22 is disposed in the sliding groove 216, the retaining edge 2152 of the main arm 21 stops against the outer surface of the inner plate 222 of the inner arm 22.

[0042] In this application, the inner arm 22 and the main arm 21 can form a groove-shaped nested structure to form a constrained sliding fit, which not only ensures stable relative sliding between the inner arm 22 and the main arm 21, but also prevents the inner arm 22 from coming off the main arm 21, thus ensuring the structural stability of the entire diagonal brace assembly 20.

[0043] Furthermore, the main arm 21 and the inner arm 22 are designed with multi-faceted contact. This design provides a guiding force when the inner arm 22 slides relative to the main arm 21, preventing the inner arm 22 from jamming or shifting due to uneven force. This allows for smooth and linear adjustment when the user pushes the bottom of the LED housing 10 to adjust the angle. In addition, the multi-faceted contact design between the main arm 21 and the inner arm 22 ensures guiding accuracy even after long-term use, preventing adjustment deviations caused by wear on one side.

[0044] Combination Figure 8 , Figure 9 as well as Figure 10 As shown, in some embodiments of this application, the diagonal brace assembly 20 further includes a damping block 24, which is movably disposed on the surface of the inner arm 22 facing the main arm 21, with the end of the damping block 24 away from the inner arm 22 and connected to the back of the LED housing 10.

[0045] In this embodiment, the damping block 24 is disposed in the receiving groove 224 formed by the inner plate 222 and the two side connecting plates 223. The surface of the damping block 24 can abut against the inner surface of the main plate 214 of the main arm 21. One end of the inner plate 222 in the inner arm 22 is rotatably connected to the back of the LED housing 10, and the damping block 24 is disposed near the other end of the inner plate 222. The card 23 is disposed near the damping block 24, and a clearance opening 221 for the card 23 to pass through is provided on one of the connecting bodies 2231.

[0046] When the inner arm 22 slides along the groove 216 of the main arm 21, the damping block 24 continuously abuts against the inner surface of the main board 214, thereby forming a gentle resistance. This makes the sliding process of the inner arm 22 more controllable and smoother, improving the user's operating feel during adjustment. At the same time, the damping block 24 can limit the sliding acceleration of the inner arm 22 through damping force, making the relative movement between the inner arm 22 and the main arm 21 smoother, significantly reducing the collision force between components, reducing wear between the main arm 21 and the inner arm 22, extending the overall service life of the diagonal brace assembly 20, and reducing later maintenance costs.

[0047] In some examples, the bracing assembly 20 also includes a mortise screw 25, through which the damping block 24 is movably connected to the inner arm 22. By adjusting the tightness of the mortise screw 25, the smoothness of the sliding of the inner arm 22 relative to the main arm 21 can be effectively adjusted.

[0048] When smooth adjustments are needed, such as when adjusting the angle of the LED box 10 during the initial installation, the nut screw 25 can be loosened to reduce the contact pressure between the damping block 24 and the main arm 21, thereby reducing the damping force and allowing the inner arm 22 to slide easily along the slide groove 216 of the main arm 21, reducing the operating effort.

[0049] When stable support is required, such as after the LED housing 10 is assembled or repaired to prevent accidental slippage, the nut screw 25 can be tightened to increase the contact pressure between the damping block 24 and the main arm 21, thereby increasing the damping force and increasing the sliding resistance of the inner arm 22 to counteract the slight slippage tendency caused by the weight of the LED housing 10 and prevent the LED housing 10 from loosening.

[0050] Furthermore, when the damping block 24 wears out, simply tightening the nut screw 25 slightly will increase the contact pressure between the damping block 24 and the main arm 21, restoring the original damping effect. There is no need to replace the damping block 24 or the entire assembly, thus effectively extending the service life of the entire bracing assembly 20.

[0051] like Figure 4 , Figure 5 as well as Figure 8 As shown, in some embodiments of this application, the diagonal brace assembly 20 further includes a limiting rib 26, which protrudes from the surface of the main arm 21 facing the inner arm 22 and is disposed on the side of the receiving opening 213 near the free end 212 of the main arm 21.

[0052] When the bottom of the LED housing 10 is relatively far away from the mounting surface 200, the inner arm 22 moves relative to the main arm 21. When the limiting rib 26 abuts against the card 23, the bottom of the LED housing 10 is relatively close to the mounting surface 200 by the external force. The limiting rib 26 can drive the card 23 to rotate, so that the card 23 can rotate in a set direction at the receiving opening 213, so that the end of the card 23 is engaged at the edge of the receiving opening 213 of the main arm 21.

[0053] When an external force drives the bottom of the LED housing 10 away from the mounting surface 200, the inner arm 22 slides along the slide groove 216 of the main arm 21 towards the free end 212 of the main arm 21, causing the card 23 to move synchronously until the card 23 abuts against the limiting rib 26 next to the receiving opening 213. At this point, the sliding of the inner arm 22 is physically blocked, and the card 23 is exactly at the preset position corresponding to the position of the receiving opening 213. This setting ensures that the card 23 can accurately engage with the edge of the receiving opening 213 after rotation, avoiding engagement failure and effectively improving the reliability of the diagonal brace assembly 20.

[0054] Furthermore, after the card 23 is positioned by the limiting rib 26, when the external force drives the bottom of the LED housing 10 closer to the mounting surface 200, the inner arm 22 will retract along the sliding groove 216 of the main arm 21 towards the connecting end 211 of the main arm 21. At this time, because the card 23 remains in contact with the limiting rib 26, the limiting rib 26 will apply a pushing force to the card 23 in a set direction, directly causing the card 23 to rotate around its own rotation axis. The entire process does not require additional manual manipulation of the card 23. The directional rotation and engagement of the card 23 can be completed simply by operating the LED housing 10 away from the mounting surface 200 and closer to the mounting surface 200.

[0055] This setup eliminates the need for users to monitor the status of card 23; they can simply push the LED box 10, significantly reducing operational complexity and the barrier to entry. It is particularly suitable for installation scenarios involving operation, one-handed operation, or obstructed visibility, effectively enhancing the user experience.

[0056] In some embodiments of this application, card interfaces 231 are respectively provided at both ends of card 23, and card interfaces 231 are V-shaped. When the inner arm 22 is relative to the main arm 21 and the limiting rib 26 abuts against card 23, one of the card interfaces 231 of card 23 abuts against the limiting rib 26.

[0057] When the bottom of the LED cabinet 10 is relatively close to the mounting surface 200, the limiting rib 26 can release the card 23 from the latch and drive the card 23 to rotate so that the card 23 can rotate in a set direction at the receiving port 213, so that the other card interface 231 of the card 23 is latched with the edge of the receiving port 213 of the main arm 21.

[0058] For the card 23 of this application, the two sides of the V-shaped card interface 231 form a flared guide structure. When the inner arm 22 moves the card 23 toward the limiting rib 26, even if a slight shaking occurs during the sliding process, the limiting rib 26 will automatically slide into the bottom of the card interface 231 along the V-shaped oblique side of the card interface 231, that is, it will be inserted into the apex of the V-shaped card interface 231 and finally stably abut against the preset contact point.

[0059] When the inner arm 22 slides until the card 23 engages with the limiting rib 26, the contact force is distributed and transmitted to the entire card 23 through the two inclined sides of the V-shaped card interface 231, preventing the card 23 from deforming or breaking due to local stress concentration, and ensuring the stability of the engagement between the card 23 and the limiting rib 26. At this time, the top of the V-shaped card interface 231 of the card 23 can form a locking fulcrum to restrict the rotation of the card 23.

[0060] When the inner arm 22 retracts and the limiting rib 26 pushes the card 23 to rotate, the inclined side of the V-shaped card interface 231 can provide a moving guide for the limiting rib 26, so that when the limiting rib 26 slides along the inclined side of the V-shaped card interface 231, it can guide the card 23 to rotate in the set direction, so that the other end of the card 23, the V-shaped card interface 231, is precisely aligned with the edge of the receiving opening 213 of the main arm 21, thereby ensuring the smoothness of the card 23 rotation process and ensuring the accuracy of the card 23 rotation direction.

[0061] In some other embodiments of this application, the card interface 231 of the card 23 can also be set in an arc shape. When the card 23 and the limiting rib 26 are engaged, the friction is smaller and the rotation is smoother. Furthermore, the arc shape of the card interface 231 has a stronger tolerance for small dimensional deviations, so that the contact point between the limiting rib 26 and the card 23 can be finely adjusted along the arc surface, reducing the processing accuracy requirements of the card 23.

[0062] In addition, in some embodiments, the limiting rib 26 can be omitted. For example, a magnet can be provided at the receiving port 213 of the main arm 21. The card 23 can be made of ferromagnetic material. When the inner arm 22 moves the card 23 close to the receiving port 213, the attraction force generated by the magnet can guide the card 23 to rotate in the direction of the receiving port 213, so that the card interface 231 of the card 23 can be stably attached to the receiving port 213 of the main arm 21.

[0063] like Figure 4 , Figure 6 as well as Figure 7 As shown, in some embodiments of this application, the diagonal bracing assembly 20 may further include a connecting unit 27. The connecting unit 27 includes a connector 271 and a fixing member 272 disposed on the connector 271. The connector 271 includes a connecting portion 2711 and an abutment portion 2712 and a transition portion 2713 respectively bent and connected to both sides of the connecting portion 2711. The fixing member 272 passes through the transition portion 2713.

[0064] Specifically, the connecting end 211 of the main arm 21 is provided with a connecting unit 27. The connecting unit 27 on the main arm 21 is a first connecting unit 2701. The connecting end 211 of the main arm 21 is rotatably connected to the connecting part 2711 of the first connecting unit 2701. The fixing member 272 of the first connecting unit 2701 is used to fix it on the mounting surface 200. The abutting part 2712 of the first connecting unit 2701 is set towards the LED box 10.

[0065] The inner arm 22 is provided with a connecting unit 27 at the end of the connecting end 211 away from the main arm 21. The connecting unit 27 on the inner arm 22 is a second connecting unit 2702. The end of the inner arm 22 is rotatably connected to the connecting part 2711 of the second connecting unit 2702. The fixing part 272 of the second connecting unit 2702 is fixed to the back of the LED box 10. The abutting part 2712 of the second connecting unit 2702 is set towards the mounting surface 200.

[0066] In this application, the connector 271 includes a connecting portion 2711 and an abutting portion 2712 and a transition portion 2713 respectively bent and connected to both sides of the connecting portion 2711. The connector 271 has a C-shaped structure. This arrangement can effectively disperse the lateral and longitudinal stress caused by the weight of the LED cabinet 10 or the vibration of the external environment, and prevent the connector 271 from bending or breaking due to excessive local stress, thus ensuring the stability of the connection between the main arm 21 and the mounting surface 200, and the inner arm 22 and the LED cabinet 10.

[0067] In this embodiment, both the first connecting unit 2701 and the second connecting unit 2702 have connecting holes in their transition portions 2713, and a fixing member 272 passes through these holes. Mounting holes are provided on the back of the LED housing 10 and at corresponding positions on the mounting surface 200. The fixing member 272 passes through these mounting holes, allowing the first connecting unit 2701 to be fixed to the mounting surface 200, and the second connecting unit 2702 to be fixed to the back of the LED housing 10. This fixes the main arm 21 to the mounting surface 200 and the inner arm 22 to the back of the LED housing 10. The fixing member 272 can be a screw, pin, or similar fastener.

[0068] In addition, the diagonal brace assembly 20 may also include a rotating member 281 and a rotating shaft 282. The rotating member 281 may be configured in a Z-shape. The rotating member 281 is fixedly provided on the connecting portion 2711 of the first connecting unit 2701. The connecting end 211 of the main arm 21 is rotatably mounted on the rotating member 281 of the first connecting unit 2701 through the rotating shaft 282, so that the main arm 21 is rotatably connected to the connecting portion 2711 of the first connecting unit 2701.

[0069] A rotating member 281 is fixedly provided on the connecting part 2711 of the second connecting unit 2702. The end of the inner arm 22 is rotatably mounted on the rotating member 281 of the second connecting unit 2702 through the rotating shaft member 282, so that the inner arm 22 is rotatably connected to the connecting part 2711 of the second connecting unit 2702.

[0070] In some examples, the bracing assembly 20 may also include a buffer pad 29, with the buffer pad 29 provided on the surface of the abutment portion 2712 of the first connecting unit 2701 facing the LED housing 10 and the surface of the abutment portion 2712 of the second connecting unit 2702 facing the mounting surface 200.

[0071] The buffer pad 29 can be made of soft, elastic materials, such as silicone, EVA cushioning cotton, or rubber. When adjusting the LED housing 10, the buffer pad 29 will come into contact with the contact surface and mounting surface 200 before the abutment part 2712. The buffer pad 29 absorbs the instantaneous impact force through its own elastic deformation, preventing the abutment part 2712 from directly impacting the LED housing 10 and the mounting surface 200, thus avoiding structural damage caused by hard contact.

[0072] In addition, such as Figure 1 and Figure 6 As shown, in some embodiments of this application, the LED all-in-one machine 100 includes multiple rows of LED cabinets 10 spliced ​​together, and at least two LED cabinets 10 are provided with diagonal bracing components 20 on their back sides.

[0073] In some examples, the diagonal bracing assembly 20 can be disposed on the back of spaced-apart LED boxes 10, such as on the back of the first and last LED boxes 10, or on the back of the first and middle LED boxes 10, to provide support from different positions in the width direction. Furthermore, in some examples, the diagonal bracing assembly 20 can also be disposed on the back of adjacent LED boxes 10.

[0074] The following describes the installation of an LED all-in-one machine 100 with 5 rows of LED cabinets 10. The back of the first row of LED cabinets 10 and the back of the fourth row of LED cabinets 10 in the LED all-in-one machine 100 are provided with diagonal bracing components 20.

[0075] First, the top of the first row of LED cabinets 10 is rotatably hung on the mounting surface 200. When the first row of LED cabinets 10 is in a natural vertical state, the inner arm 22 of the diagonal support assembly 20 behind it is housed inside the main arm 21, that is, the inner arm 22 is retracted to the initial position. Then, the fixing piece 272 of the first connecting unit 2701 on the main arm 21 is fixed to the mounting surface 200, completing the installation of the first row of LED cabinets 10. Next, the top of the second row of LED cabinets 10 is rotatably hung on the mounting surface 200, so that it is connected to the first row of LED cabinets. 10. Tighten the connecting screws between the first and second LED cabinets 10; then install the third, fourth, and fifth LED cabinets 10 in sequence and tighten the connecting screws of adjacent columns; before installing the fifth LED cabinet 10, use the same installation method as the first column to complete the assembly of the diagonal brace assembly 20 of the fourth LED cabinet 10, and fix the fixing piece 272 of the first connecting unit 2701 on the main arm 21 to the mounting surface 200. Through the above steps, the installation of all LED cabinets 10 is completed. In other examples, other LED integrated machines 100 of different sizes can also adopt the above installation method.

[0076] like Figure 11 As shown, when maintaining the back of the LED all-in-one machine 100, the operator can flip the LED all-in-one machine 100 upwards. Before flipping, the inner arm 22 of the inclined support assembly 20 behind the LED housing 10 is retracted to the initial position of the main arm 21, and the card 23 is in state A. The LED all-in-one machine 100 is flipped upwards, and the bottom of the LED box 10 moves away from the mounting surface 200. The inner arm 22 moves relative to the main arm 21, and the card 23 gradually approaches the limiting rib 26 and is in state AB. When the card 23 abuts and engages with the limiting rib 26, the inner arm 22 reaches its maximum extension and retraction, and the card 23 is in state B. Then the LED box 10 is slowly lowered, and the card 23 gradually moves away from the limiting rib 26 and is in state BC. During the process of moving away from the limiting rib 26, the limiting rib 26 can drive the card 23 to rotate at the receiving opening 213, so that the end of the card 23 engages with the receiving opening 213 of the main arm 21. At this time, the card 23 is in state C.

[0077] When card 23 is in state C, the main arm 21 and inner arm 22 can be supported between the LED housing 10 and the mounting surface 200, and the operator can complete the installation or maintenance of the control device 30 in the space between the LED housing 10 and the mounting surface 200.

[0078] After installation or maintenance, the operator can flip the LED all-in-one machine 100 upwards again. Card 23 gradually approaches the limiting rib 26 and is in state CD. Card 23 abuts against the limiting rib 26 and is in state D. When card 23 is in state D, the inner arm 22 reaches its maximum extension stroke. Then, the LED box 10 is slowly lowered. Card 23 gradually moves away from the limiting rib 26 and is in state DA. As card 23 moves away from the limiting rib 26, the inner arm 22 gradually retracts. Card 23 will collide with the side receiving port 213 of the main arm 21 and return to state A.

[0079] For the LED all-in-one machine of this application, when an external force drives the bottom of the LED cabinet to move, the inner arm can slide along the main arm and drive the card into the receiving slot. After the card rotates at the receiving slot, it engages with the edge of the main arm, forming a mechanical lock. This setting allows for quick adjustment and fixation of the LED cabinet's support angle without additional tools, making it particularly suitable for scenarios requiring frequent debugging or temporary installation, facilitating quick and efficient maintenance of the LED cabinet from behind. Furthermore, the main arm, inner arm, and mounting surface form a triangular support system, utilizing the geometric stability of a triangle to resist the LED cabinet's own weight and external loads. This support system can convert vertical loads into axial pressure and transmit it to the mounting surface, while the engaging action of the card enhances the rigidity of the joints, ensuring the stability of the LED cabinet's oblique support.
