[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.
[0022] Reference Figure 1 and Figure 3 This utility model provides an embodiment of a foldable display screen, including a placement box 1 and a fixing base 3. A mounting base 7 is fixedly connected to the upper part of the fixing base 3. An electric push rod 8 is fixedly connected inside the fixing base 3. A push plate 9 is fixedly connected to the output end of the electric push rod 8. A positioning plate 10 is fixedly connected to the upper part of the push plate 9. Hinges 12 are fixedly connected to both sides of the upper part of the positioning plate 10. Movable support rods 13 are rotatably connected inside each of the two hinge blocks 12. Fixing blocks 14 are fixedly connected to both sides of the interior of the mounting base 7. One end of a connecting rod 15 is rotatably connected to the opposite side of block 14. The other ends of the two connecting rods 15 are rotatably connected to both sides of the movable support rod 13. A connecting plate 16 is fixedly connected to the opposite side of the two movable support rods 13. The display screen body 17 is fixedly connected to the left side of the connecting plate 16. Limiting blocks 11 are fixedly connected to both sides of the bottom of the positioning plate 10. The two limiting blocks 11 are slidably connected inside the mounting base 7. The push plate 9 is slidably connected inside the mounting base 7. The display screen body 17 is rotatably connected to the upper part of the mounting base 7.
[0023] When the electric push rod 8 is activated, its output end drives the push plate 9 to move. The push plate 9 slides inside the mounting base 7, simultaneously driving the positioning plate 10 and the limiting block 11 to move synchronously. The positioning plate 10 and the limiting block 11 work together to ensure the accuracy of the push plate 9 during movement and the precision of its position. The limiting block 11 slides inside the mounting base 7, restricting and guiding the movement of the positioning plate 10. Under the synergistic action of the two limiting blocks 11, the positioning plate 10 drives the hinge block 12 to move. As the hinge block 12 moves, the movable support rod 13 and the connecting rod 15 rotate accordingly. The movable support rod 13 is part of the rotation mechanism. It is connected to the positioning plate 10 through the hinge block 12 and to the display screen body 17 through the connecting rod 15, playing the role of transmitting rotational force. The connecting rod 15 connects the movable support rod 13 and the connecting plate 16. It is responsible for converting the rotation of the movable support rod 13 into the rotation of the display screen body 17. The connecting plate 16 is driven, thereby driving the display screen body 17 to start rotating.
[0024] Reference Figure 1 and Figure 2 A cylinder 2 is fixedly connected inside the placement box 1. A fixed seat 3 is fixedly connected to the output end of the cylinder 2. Limiting components are fixedly connected to both sides of the fixed seat 3. The limiting components are used to limit the fixed seat 3. The limiting components include sliders 4 and slide rods 5. Multiple sliders 4 are fixedly connected to both sides of the fixed seat 3. Multiple sliders 4 are slidably connected to the outside of slide rods 5. Multiple slide rods 5 are fixedly connected to both sides of the inside of the placement box 1. Buffer springs 6 are sleeved on the outside of multiple slide rods 5. Multiple sliders 4 are slidably connected to both sides of the inside of the placement box 1. One end of multiple buffer springs 6 is fixedly connected to the inside of the placement box 1. The other end of multiple buffer springs 6 is fixedly connected to the bottom of sliders 4. The fixed seat 3 is slidably connected to the inside of the placement box 1. The display screen body 17 is slidably connected to the inside of the placement box 1.
[0025] After use, cylinder 2 is activated, and its output end drives the fixed base 3 to move downward. As the fixed base 3 moves, multiple sliders 4 on the fixed base 3 slide smoothly outside the slide bar 5. The slide bar 5 provides a sliding track for the sliders 4, ensuring that the sliders 4 can move smoothly and correctly. This causes multiple sliders 4 to move downward synchronously, applying pressure to the buffer spring 6, which is gradually squeezed. During the squeezing process, the buffer spring 6 effectively absorbs the vibration generated during the movement, ensuring the smooth movement of the fixed base 3. This allows the fixed base 3 to reliably drive the display screen body 17 into the interior of the placement box 1. The placement box 1 is the storage space for the display screen body 17. It provides a protective closed environment for the display screen, preventing it from being affected by external factors during handling and transportation, thereby ensuring the safety of the display screen.
[0026] Working principle: When in use, the electric push rod 8 is activated. The output end of the electric push rod 8 drives the push plate 9 to move. As the push plate 9 moves, it slides inside the mounting base 7. The movement of the push plate 9 drives the positioning plate 10 and the limiting block 11 to move, causing the limiting block 11 to slide inside the mounting base 7. With the cooperation of the two limiting blocks 11, the positioning plate 10 drives the hinge block 12 to move. When the hinge block 12 moves, it drives the movable support rod 13 and the connecting rod 15 to rotate. Under the action of the movable support rod 13 and the connecting rod 15, the connecting plate 16 drives the display screen body 17 to begin rotating. This allows the display screen body 17 to rotate to a position where it is horizontal or vertical to the mounting base 7, facilitating easy adjustment of the display screen body 17. The folding mechanism automatically adjusts to the most suitable position, reducing its size for easy storage and carrying. After use, activating cylinder 2 causes the output end of cylinder 2 to move the fixed base 3 downwards. As the fixed base 3 moves, it causes multiple sliders 4 to slide outside the slide rod 5. The downward movement of the sliders 4 compresses the buffer spring 6, which absorbs the vibration. This allows the fixed base 3 to move the display screen body 17 stably into the placement box 1 until the display screen body 17 is completely inside the placement box 1. This facilitates the storage and handling of the display screen body 17, better protects it, and prevents damage during handling and transportation.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
