DETAILED DESCRIPTION

[0031] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0032] With reference to Figures 1-3 The present application provides an embodiment: a foldable structure of an LED display screen, comprising a support plate 1, the support plate 1 is the basic structure of the entire display screen, bearing the weight of other components and providing support, the top of the support plate 1 is fixedly connected with a fixed frame 2, responsible for fixing and supporting the rotating function of a rotating frame 3, the outer wall of the fixed frame 2 is rotatably connected with the rotating frame 3, one side of the rotating frame 3 is fixedly connected with a connecting block 4, one side of the connecting block 4 is fixedly connected with a support frame 5, so that the support frame 5 can be folded and unfolded, the inside of the support frame 5 is provided with a screen 6, the inside of the rotating frame 3 is provided with a support assembly, and the top of the support plate 1 is provided with a connecting assembly;

[0033] The support assembly comprises a support column 7, the outer wall of the support column 7 is fixedly connected in the rotating frame 3, the outer wall of the support column 7 is rotatably connected with a connecting rod 8, one side of the connecting rod 8 is fixedly connected with a sliding column 9, and the main function is to transmit the motion force, so that the sliding column 9 slides along the sliding groove 10, the inside of the fixed frame 2 is provided with a sliding groove 10, the sliding column 9 is slidably connected in the sliding groove 10, the outer wall of the sliding column 9 is rotatably connected with a protruding block 11, the protruding block 11 is in contact with the fixed frame 2, and the function of the protruding block 11 is to be in contact with the inner wall of the fixed frame 2, so as to prevent the sliding column 9 from being excessively deviated.

[0034] Specifically, in the process of using the display screen, when it needs to be folded, first push the support frame 5 and the screen 6 inside it backward. The support frame 5 will be transmitted through the connecting block 4 on both sides of the support frame 5 after being subjected to external force. The connecting block 4 in turn pushes the rotating frame 3 on one side when subjected to external force. The rotating frame 3 is installed on the outer wall of the fixed frame 2. Through the rotation of the rotating frame 3, the corresponding displacement of the support column 7 inside it is driven. The movement of the support column 7 drives the connecting rod 8 to move. The connecting rod 8 is tightly connected with the slide column 9. The slide column 9 slides in the track through the guidance of the sliding groove 10, so that the support frame 5 is gradually folded and placed on the upper side of the support plate 1. After the support frame 5 is folded, the unfolding process is also simple and efficient. When the display screen needs to be unfolded, the support frame 5 is only pulled away from the folded state, and it is stably erected on one side of the support plate 1. In order to ensure the stability and reliability of the support frame 5, the convex block 11 on the outer wall of the slide column 9 will cooperate with the inside of the fixed frame 2 during unfolding. The convex block 11 will be clamped in the inner wall of the fixed frame 2, so as to ensure that the display screen can be firmly fixed after unfolding, prevent loosening or tilting caused by external force, and effectively ensure the use stability and safety of the display screen.

[0035] Referring to Figure 2 , Figure 4 and Figure 5 , the connecting assembly includes a hollow column 12 fixedly connected at the top of the support plate 1. A clamping groove 13 is formed in the inside of the hollow column 12. The design of the clamping groove 13 enables the connecting column 14 to slide tightly, and at the same time ensures that the connecting column 14 will not easily fall off. The support frame 5 is fixedly connected with the connecting column 14 on one side. An empty slot 20 is formed in the inside of the connecting column 14, which is used to accommodate the clamping plate 15 and its sliding parts. The clamping plate 15 is slidably connected in the inside of the empty slot 20. The clamping plate 15 is fixedly connected with the telescopic column 18 on one side. The clamping plate 15 is fixedly connected with the clamping block 16 on the other side. The clamping block 16 is slidably connected in the inside of the connecting column 14 and the clamping groove 13. The connecting column 14 is fixedly connected with the fixed column 17 in the inside. The telescopic column 18 is slidably connected in the inside of the fixed column 17. The fixed column 17 is used to support the movement of the telescopic column 18. The fixed column 17 is sleeved with the spring 19 on the outer wall. One end of the spring 19 is fixedly connected in the inside of the connecting column 14. The other end of the spring 19 is fixedly connected on one side of the clamping plate 15. It provides enough elastic force to ensure that the support frame 5 can maintain a stable fixed state after being unfolded.

[0036] Specifically, the connecting column 14 on one side of the support frame 5 plays an important role in the folding process. The connecting column 14 is precisely inserted into the hollow column 12 above the support plate 1. When the connecting column 14 is inserted into the hollow column 12, the internal clamping block 16 is subjected to the extrusion action of the inner wall of the hollow column 12, causing the clamping block 16 to slide inward along the connecting column 14. Finally, the sliding of the clamping plate 15 drives the compression of the spring 19 on one side. The contraction of the spring 19 provides additional stability. When the support frame 5 is completely folded and placed on the support plate 1, the spring 19 performs a force-releasing rebound action, allowing the clamping block 16 to automatically clamp into the clamping groove 13 inside the hollow column 12, thereby ensuring firm and stable connection between the support frame 5 and the support plate 1. When unfolded, the user only needs to manually press the clamping block 16 to slide it out of the clamping groove 13, release the support frame 5, and quickly restore it to the working state. The entire folding and unfolding process is simple and efficient, greatly improving the convenience of use and the stability of the structure.

[0037] Working principle: During the use of the display screen, when it needs to be folded, first push the support frame 5 and the screen 6 inside it backward. The support frame 5 is forced to move the connecting block 4 of the side wall, which drives the rotating frame 3 on one side to rotate outside the fixed frame 2. At the same time, the support column 7 inside the rotating frame 3 drives the connecting rod 8 to move, and the connecting rod 8 is forced to drive the sliding column 9 inside the sliding groove 10 to slide. Finally, the support frame 5 is folded and placed on the support plate 1. When unfolded, simply pull the support frame 5 apart and stand it on one side of the support plate 1. At this time, rotate the protrusion 11 outside the sliding column 9 to make the protruding part clamp inside the fixed frame 2 to complete the fixation, thereby achieving the effect of easy folding of the display screen. During the folding process, the connecting column 14 on one side of the support frame 5 is inserted into the hollow column 12 above the support plate 1. At the same time, the clamping block 16 inside the connecting column 14 is subjected to the extrusion of the inner wall of the hollow column 12, causing the clamping block 16 to slide the clamping plate 15 on one side into the hollow slot 20 inside the connecting column 14. At the same time, the clamping plate 15 will extrude the spring 19 connected on one side, causing it to contract. When the support frame 5 is completely folded on the support plate 1, the spring 19 rebounds to release the force, thereby driving the clamping block 16 to clamp into the clamping groove 13 inside the hollow column 12 to complete the fixation. When unfolded, simply press the clamping block 16 manually to slide it out of the clamping groove 13, thereby achieving the effect of stable connection between the support plate 1 and the screen 6 during folding.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
