Description

Technical Field

[0001] This utility model relates to the field of LED display equipment technology, and more specifically, it relates to a portable foldable LED display. Background Technology

[0002] LED displays are now the mainstream screen display devices in the market. In order to be used in workplaces such as conference rooms, foldable modular LED displays have been launched on the market to improve the performance of the images.

[0003] Most common foldable LED displays have a simple structure, using brackets and other structures to connect multiple screens to form a foldable LED display combination. However, when folding for storage, this common structure typically folds towards the back of the screen, leaving one side exposed and lacking effective protection. Additional storage and protection devices are needed to ensure the display's safety, making it inconvenient to use. Furthermore, folding such LED displays usually requires moving the device for storage or transporting it to the workplace. Since common LED displays have simple structures that don't require moving mechanisms, manual handling is necessary, causing inconvenience for users. Additionally, existing LED displays often have their screen structure housed within a casing, which supports their operation. This casing inevitably has a certain thickness. When foldable LED displays are unfolded and joined together, the hollow space replaces the corresponding casing, leaving a gap in the middle of the screen where no image can be displayed, affecting the viewing experience.

A support rod 5 is provided inside the sliding frame 4. The support rod 5 is slidably engaged with the sliding frame 4. A connecting plate 6 is provided between the support rods 5. The two ends of the connecting plate 6 are rotatably connected to the support rods 5.

[0031] A handle 7 is rotatably connected to the connecting plate 6. A first sliding groove 8 is opened on one side of the protective shell 3, and a second sliding groove 9 is opened on the side of the protective shell 3 adjacent to the first sliding groove 8. A first bracket 10 is slidably connected in the first sliding groove 8, and a second bracket 11 is slidably connected in the second sliding groove 9. A limiting rod 12 is slidably connected in both the first sliding groove 8 and the second sliding groove 9. A limiting groove 13 is opened on both the first bracket 10 and the second bracket 11. The limiting rod 12 cooperates with the limiting groove 13. A support wheel 14 is provided at the lower end of both the first bracket 10 and the second bracket 11.

[0032] In this embodiment, when using the device, the protective shell 3 is moved by controlling the sliding frame 4 and the support rod 5 to slide together, so that the protective shell 3 on both sides, along with the corresponding first screen 1 and second screen 2, moves away from the connecting plate 6, avoiding interference with the subsequent rotation groove. Then, the support rod 5 and the connecting plate 6 are rotated relative to each other, so that the support rod 5 and the connecting plate 6 remain parallel, allowing the protective shell 3 to unfold with the first screen 1 and second screen 2. Then, through the sliding frame 4 and the support rod 5, the sides of the first screen 1 and second screen 2 are brought together, completing the unfolding of the display screen. When storing, the above steps are reversed, so that the support rod 5 and the connecting plate 6 are in a perpendicular state. At this time, the front of the first screen 1 and second screen 2 are brought together and located inside the protective shell 3, which protects the first screen 1 and second screen 2.

[0033] More specifically, when the equipment is in the stowed state, it can be moved by carrying handle 7, facilitating its transport. By controlling the first bracket 10 to slide along the first slide groove 8, the first bracket 10 slides out with the support wheel 14. Then, by controlling the corresponding limiting rod 12 to insert into the limiting groove 13, the first bracket 10 is positioned, so that multiple first brackets 10 contact the ground through the support wheel 14, supporting the equipment and facilitating its movement. When the equipment is in the unfolded state, the second bracket 11 can be controlled to slide out along the second slide groove 9, sliding out with the corresponding support wheel 14. Then, by the corresponding limiting rod 12 cooperating with the limiting groove 13, the second bracket 11 is positioned, so that the second bracket 11 contacts the ground through the support wheel 14, supporting the equipment and facilitating its movement.

[0034] Please see Figure 1 As one implementation method for screen bonding: the outer end of the protective shell 3 is provided with a protective frame 15, and the two ends of the protective frame 15 are provided with protective side frames 16.

The rotating frame 101 and the fixed block 20 are respectively set on the protective frame 15 on both sides.

[0037] Specifically, when storing the equipment, the two sets of protective frames 15 are attached together and supported by the rotating frame 101, so that the rotating shaft 18 rotates to adjust the angle of the fixed frame 19. Then, the fixed frame 19 is controlled to slide, so that the other end of the fixed frame 19 moves to the side of the fixed block 20. Then, the rotating shaft 18 is controlled to align the fixed frame 19 with the fixed groove 21, so that the fixed frame 19 slides and the other end of the fixed frame 19 is inserted into the fixed groove 21, thus restricting the two sets of protective frames 15.

[0038] Please see Figures 1-4 As a further embodiment of the fixed frame: a return spring 22 is provided between the fixed frame 19 and the rotating shaft 18, and a guide rod 23 is provided on the fixed frame 19, with the guide rod 23 slidingly engaged with the rotating shaft 18.

[0039] Specifically, the return spring 22 provides a thrust, causing the fixed frame 19 to move away from the fixed block 20 and remain stable under the guidance of the guide rod 23, so that the fixed frame 19 and the fixed block 20 are stably engaged.

[0040] Please see Figures 2-4 As a further embodiment of the sliding frame: the sliding frame 4 is provided with fixing bolts 24, and the support rod 5 is provided with fixing holes 25. Multiple fixing holes 25 are provided and cooperate with fixing bolts 24.

[0041] Specifically, by adjusting the fixing bolt 24, the fixing bolt 24 is moved on the sliding frame 4 and inserted into the fixing hole 25 to fix the position of the support rod 5.

The limiting rod 12 slides in cooperation with the storage groove 26 and the control port 27. A pressure spring 28 is provided in the storage groove 26, and the pressure spring 28 cooperates with the limiting rod 12.

[0043] Specifically, the storage slot 26 provides space, the control port 27 facilitates control, and the movement of the limiting rod 12 is easily controlled. The pressure spring 28 applies pressure to the limiting rod 12, so that the limiting rod 12 remains stable when it is engaged with the limiting slot 13.

[0044] Please see Figures 3-5 As a further embodiment of the bracket: both the first bracket 10 and the second bracket 11 are provided with limiting sliders 29, and both the first slide groove 8 and the second slide groove 9 are provided with limiting slide grooves 30.

[0045] Specifically, when the first support 10 and the second support 11 move, the movement of the first support 10 and the second support 11 is kept stable by the sliding engagement of the limiting slider 29 and the limiting groove 30.

[0046] Please see Figure 5 As a further embodiment of the second support: the lower end of the second support 11 is provided with a wheel frame 31, and the support wheel 14 is rotatably connected to both ends of the wheel frame 31.

[0047] Specifically, the support of the wheel frame 31 enables multiple sets of support wheels 14 to cooperate with the second bracket 11, making the support of the second bracket 11 more stable.

[0048] In summary, during the use or operation of the overall equipment:

[0049] When using the device, the protective shell 3 is moved by adjusting the fixing bolt 24, which moves on the sliding frame 4 away from the fixing hole 25, releasing the restriction. The sliding frame 4 and support rod 5 slide together, allowing the protective shell 3 on both sides, along with the corresponding first screen 1 and second screen 2, to move away from the connecting plate 6 and to a suitable distance, avoiding interference with the subsequent rotation slot. Then, the support rod 5 and connecting plate 6 are rotated relative to each other, keeping them parallel, allowing the protective shell 3 to unfold with the first screen 1 and second screen 2. The sliding frame 4 and support rod 5 then slide together, bringing the sides of the first screen 1 and second screen 2 together. The fixing bolt 24 and fixing hole 25 fix the relative position of the sliding frame 4 and support rod 5, completing the unfolding of the display screen. The edges of the unprotected sides of the first screen 1 and second screen 2 will directly adhere together, minimizing the gap between them and reducing the impact of the bezel on the screen image. When storing, the above steps are reversed, so that the support rod 5 and the connecting plate 6 are in a perpendicular state. At this time, the front of the first screen 1 and the second screen 2 are attached together and located inside the protective shell 3. The protective shell 3 protects the first screen 1 and the second screen 2. The outer sides of the first screen 1 and the second screen 2 are protected by the cooperation of the protective frame 15 and the protective side frame 16. The unprotected side of the screen is shielded by the protective plate 17. When storing, the two sets of protective frames 15 are attached together and supported by the rotating frame. The rotating shaft 18 is rotated to adjust the angle of the fixed frame 19. Then, the fixed frame 19 is controlled to slide, so that the other end of the fixed frame 19 moves to the side of the fixed block 20. Then, the rotating shaft 18 is controlled to align the fixed frame 19 with the fixed groove 21. The fixed frame 19 is slid and the other end of the fixed frame 19 is inserted into the fixed groove 21. The return spring 22 provides the thrust and is kept stable under the guidance of the guide rod 23, so that the fixed frame 19 and the fixed block 20 are stably engaged.

[0050] When the device needs to be moved, if it is in the storage state, it can be carried by the handle 7 for easy transport. The storage slot 26 provides space, and the control port 27 facilitates control of the movement of the limiting rod 12. The limiting rod 12 moves away from the limiting slot 13 and engages the limiting mechanism. The first bracket 10 slides along the first slide groove 8, and the sliding engagement of the limiting slider 29 with the limiting slide groove 30 ensures stable movement. This allows the first bracket 10 to slide out with the support wheel 14. Then, the corresponding limiting rod 12 is inserted into the limiting slot 13. Under the pushing force of the pressure spring 28, the limiting rod 12... In conjunction with the limiting groove 13, the first bracket 10 is positioned. Multiple first brackets 10 contact the ground via support wheels 14 to support the equipment and facilitate its movement. If the equipment is in the unfolded state, the second bracket 11 can be controlled to slide out along the second sliding groove 9, along with the corresponding support wheel 14. Then, it is positioned by the corresponding limiting rod 12 in conjunction with the limiting groove 13, so that the second bracket 11 contacts the ground via the support wheels 14 to support the equipment and facilitate its movement. Furthermore, the second bracket 11 is supported by the wheel frame 31, which allows multiple sets of support wheels 14 to cooperate with the second bracket 11, making the support of the second bracket 11 more stable.

[0051] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
