Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and more specifically, to a foldable LED-LCD screen with tensile-resistant conductive lines. Background Technology

[0002] A display screen is a tool used to show electronic documents onto a screen via specific transmission equipment. These electronic documents can be in various forms, such as text, images, and videos. The display screen allows users to see the content by reflecting light to their eyes. The working principle of a display screen typically involves controlling semiconductor light-emitting elements, which display various image information by turning on and off.

[0003] Foldable screens, as an emerging display technology, have received widespread attention in recent years. The most significant feature of this type of screen is its ability to fold and unfold while maintaining display quality. This characteristic allows the device to be folded up when not in use, greatly reducing its size and improving portability. Simultaneously, it can be unfolded into a larger screen when in use, providing a better visual experience.

[0004] However, traditional foldable screens face several challenges in practical applications. One of the biggest problems is that the conductive circuitry is susceptible to stretching and stress during folding and unfolding. These conductive circuits are typically used to transmit electrical signals and control the screen's display. When the screen is folded or unfolded, the conductive circuitry is subjected to varying degrees of stretching and compression, which can lead to decreased conductivity or even breakage. Once the conductive circuitry is damaged, the screen's display quality will be affected, and in severe cases, it may even malfunction.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A foldable LED-LCD screen with tensile-resistant conductive circuitry includes a base, a first screen connected above the base, a second screen connected above the first screen via a hinge, a control box on one side of the first screen, a controller inside the control box, the controller being electrically connected to a connecting wire, a connecting ring connected to the outside of the connecting wire, a connecting rod connected to the outside of the connecting ring, the connecting rod being connected to a movable plate, and a fixed plate connected to the movable plate via a telescopic spring.

[0009] Furthermore, the connecting wire is electrically connected to the second screen, and the first screen has a conveying channel inside, which is matched with the connecting wire.

[0010] Furthermore, to ensure that the movable plate can only move horizontally, a limiting rod is provided inside the telescopic spring. One end of the limiting rod is fixedly connected to the movable plate, and the other end is connected through the fixed plate.

[0011] Furthermore, the mounting plate is fixedly connected to the control box, the control box has a partition inside, the connecting wires pass through the partition, and the controller is located below the partition.

[0012] Furthermore, a fixing rod is connected to one side of the second screen, and a connecting plate is fitted onto the fixing rod. A through hole is provided on one side of the connecting plate.

[0013] Furthermore, a screw is connected to one side of the first screen, the screw matches the through hole, and a nut is threaded onto the screw.

[0014] Furthermore, a limiting ring is provided on the outside of the connecting wire, and the limiting ring is fixedly connected to the control box.

[0015] Furthermore, the bottom of the base is connected to rollers.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) By using components such as connecting rings, connecting rods and moving plates, the connecting wire can be moved when stretched, thereby moving the connecting wire and stretching the bent wire, reducing the stress and damage to the wire.

[0018] (2) By setting a fixing rod, a connecting plate and a screw on one side of the second screen, when the second screen is rotated above the first screen, the stability and reliability of the screen in the unfolded state can be effectively improved by passing one end of the connecting plate through the screw and fixing it with a nut, so that users can have a good experience during use.

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.

[0027] According to an embodiment of the present invention, a foldable LED-LCD screen with tensile-resistant conductive lines is provided.

[0028] Example 1

[0029] like Figures 1-4As shown, the foldable LED-LCD screen with tensile conductive circuit according to an embodiment of the present invention includes a base 1, which provides a stable foundation support for the entire device and ensures that the screen remains stable during use. A first screen 2 is connected above the base 1, and a second screen 3 is connected above the first screen 2 via a hinge for displaying images. A control box 4 is provided on one side of the first screen 2, and a controller 5 is provided inside the control box 4. The controller 5 is responsible for processing input signals and controlling the operation of the screen through a connecting wire 21. The controller 5 is electrically connected to the first screen 2 via a wire and is electrically connected to the connecting wire 21. The connecting wire 21 is used to transmit electrical signals and control the display of the second screen 3. A connecting ring 6 is connected to the outside of the connecting wire 21 for moving the connecting wire 21. A connecting rod 7 is connected to one side of the outside of the connecting ring 6 for transmitting the movement of the connecting ring 6 to a moving plate 8. The connecting rod 7 ensures that the connecting ring 6 and the moving plate 8 can move when the wire is stretched, thereby achieving the stretching and protection of the connecting wire 21. The connecting rod 7 is connected to the moving plate 8 to drive the connecting rod 7 to move. The moving plate 8 is connected to the fixed plate 10 through a telescopic spring 9. The telescopic spring 9 is an elastic element used to provide a certain elastic force to help the connecting wire 21 gradually return to its original shape during the contraction process. The connecting wire 21 is electrically connected to the second screen 3. The first screen 2 has a conveying channel 11 inside, which matches the connecting wire 21 to provide an orderly path for the connecting wire 21, avoiding the wire from becoming messy or tangled under external force. The spring 9 has a limiting rod 12 inside, which is used to limit the movement range of the moving plate 8, prevent the moving plate 8 from excessive displacement during the extension and retraction process, and ensure that the moving plate 8 can only move in the horizontal direction. One end of the limiting rod 12 is fixedly connected to the moving plate 8, and the other end is connected through the fixed plate 10. The fixed plate 10 is fixedly connected to the control box 4. The control box 4 has a partition 13 inside, and the connecting wire 21 is connected through the partition 13. The controller 5 is located below the partition 13. The connecting wire 21 has a limiting ring 19 on the outside, which is used to limit the movement range of the connecting wire 21. There are two limiting rings 19. The lower limiting ring 19 is connected to the connecting wire 21, and the limiting ring 19 is fixedly connected to the control box 4.

[0030] like Figures 1-4As shown, a fixing rod 14 is connected to one side of the second screen 3. The fixing rod 14 is a rod-shaped structure installed on one side of the second screen 3. Its function is to provide a fixing point for connecting and fixing the connecting plate 15. The connecting plate 15 is sleeved on the fixing rod 14. The connecting plate 15 is a plate-shaped structure installed on the fixing rod 14. One end of it has a through hole 16, which can be connected to the screw 17. The connecting plate 15 has a through hole 16 on one side for the screw 17 to pass through. The first screen 2 is connected to a screw 17 on one side. Its function is to provide a fixing point for connecting and fixing the connecting plate 15. The screw 17 matches the through hole 16. A nut 18 is threaded on the screw 17. A roller 20 is connected to the bottom end of the base 1 to facilitate the user to move and use the screen in different situations.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, when the second screen 3 needs to be unfolded, the second screen 3 is rotated around the hinge to rotate it above the first screen 2. During the rotation of the second screen 3, the distance between the second screen 3 and the connecting box 4 becomes shorter, and the connecting wire 21 can automatically retract under the action of the telescopic spring 9, thereby reducing the stress and damage to the wire. Then, by moving the connecting plate 15, the through hole 16 on the connecting plate 15 is placed outside the screw 17. Then, by rotating the nut 18, the connecting plate 15 can be fixed on the screw 17, thereby making the connection between the first screen 2 and the second screen 3 stable. When the second screen 3 needs to be folded, the nut 18 is removed, the connecting plate 15 is moved, the fixing effect on the second screen 3 is invalidated, and then the second screen 3 is folded. During the folding process, since the distance between the first screen 2 and the second screen 3 becomes farther, the connecting wire 21 can drive the connecting ring 6 to move during the extension process. The movement of the connecting ring 6 further drives the connecting rod 7 and the moving plate 8 to move, thereby extending the connecting wire 21. This design effectively reduces bending and damage to the wire during folding, ensuring that the wire maintains good conductivity and service life even after multiple folds and unfolds.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
