Description

Technical Field

[0001] This application relates to the field of screen technology, and in particular to a rollable flexible-rigid composite screen. Background Technology

[0002] With the continuous development of technology, people have put forward higher requirements for screen performance and ease of use. Traditional rigid screens have significant limitations in terms of portability, making it difficult to meet people's needs for large-screen displays that are easy to store in mobile scenarios. While flexible screens have the characteristics of being bendable and foldable, they lack sufficient support strength when used alone, making them prone to deformation and damage, which affects the display effect and lifespan. Currently available rollable screens are either complex in structure and expensive, or prone to wrinkles and wear during the rolling process, resulting in a decline in display quality and failing to provide users with a good user experience. Therefore, a rollable flexible-rigid composite structure screen is proposed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a rollable flexible-rigid composite screen to solve the problems mentioned in the background art.

[0004] The rollable flexible-rigid composite screen provided in this application adopts the following technical solution:

[0005] A retractable flexible-rigid composite screen includes a flexible display screen and a rewinding frame. The flexible display screen has a rigid support layer installed inside. The rigid support layer includes multiple rigid sheets and flexible hinges. Every two rigid sheets are hinged together by the flexible hinges. Connecting blocks are fixedly connected to the outer walls of the rigid sheets and the flexible hinges. The flexible display screen and the rigid support layer are connected by the connecting blocks.

[0006] The inner wall of the winding frame is equipped with a winding mechanism, which includes a fixed shaft, a winding drum, and a spring. The fixed shaft is fixedly connected to the upper and lower inner walls of the winding frame, and the winding drum is rotatably connected to the outer wall of the fixed shaft. A spring is provided in the inner cavity of the winding drum near both ends. One end of the spring is fixedly connected to the inner wall of the winding drum, and the other end is fixedly connected to the outer wall of the fixed shaft. One end of the flexible display screen is located on the outer wall of the winding drum, and the other end passes through the winding frame and is fixedly connected to an arc-shaped limiting plate.

[0007] Preferably, a limiting mechanism is installed on the outer wall of the arc-shaped limiting plate. The limiting mechanism includes a retaining strip and a shaft seat. One end of the retaining strip is rotatably connected to the inner wall of the shaft seat via a pin, and one end of the pin is fixedly connected to a knob.

[0008] Preferably, the outer wall of the card strip has multiple arc-shaped notches, which are adapted to and engaged with multiple connecting blocks. The top of the arc-shaped limiting plate has an avoidance notch, which corresponds to the card strip.

[0009] Preferably, the outer walls at both ends of the winding frame are equipped with damping mechanisms for positioning the stretching length of the flexible display screen. The damping mechanism includes extrusion discs, damping beads, slide rods, connecting rings and springs. The two extrusion discs are located inside the two ends of the winding frame, and the multiple damping beads are uniformly fixedly connected to the outer walls of the two extrusion discs in a circumferential array.

[0010] Preferably, the plurality of slide rods are uniformly fixedly connected in a circumferential array to the outer wall of the extrusion disc on the side away from the damping bead, and the ends of the slide rods away from the extrusion disc pass through the winding frame and are fixedly connected to the connecting ring. The spring is sleeved on the outer wall of the slide rod and is located between the extrusion disc and the winding frame.

[0011] Preferably, the upper and lower ends of the winding drum are fixedly connected to fixed discs, and the outer wall of the fixed discs is provided with multiple damping holes. The damping holes are adapted to and engaged with damping beads. The middle outer wall of the two fixed discs is provided with a through hole, and the fixed discs are rotatably connected to the fixed shaft through the through hole.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. It effectively solves the contradiction between portability and support in traditional screens. The flexible display screen has rollable characteristics, which greatly improves the portability of the screen and meets people's needs for large screen display and easy storage in mobile scenarios. The rigid support layer, combined with the design of the limiting mechanism, can provide stable support for the flexible display screen when it is unfolded and used, avoiding the deformation and damage problems caused by the lack of support strength when the flexible screen is used alone, thus ensuring the display effect and service life of the screen.

[0014] 2. By coordinating the winding mechanism with the damping and limiting mechanisms, the winding process is smooth and stable, reducing wrinkles and wear on the screen during winding and ensuring display quality. Furthermore, compared to complex and expensive retractable screens on the market, this structure achieves equal or even better functionality through a simple design, reducing production and usage costs and providing users with a better experience.

[0023] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0024] This application discloses a rollable rigid-flexible composite screen. (See also...) Figure 1-7 A retractable rigid-flexible composite screen includes a flexible display screen 1 and a rewinding frame 4. The flexible display screen 1 uses flexible OLED material, which has good flexibility and display performance, and can be bent and rewound.

[0025] The flexible display screen 1 has a rigid support layer 2 installed inside. The rigid support layer 2 includes multiple rigid sheets 201 and flexible hinges 202. The rigid sheets 201 are made of aluminum alloy with a thickness of 0.3-0.5mm, which ensures the support strength without being too heavy. Each pair of rigid sheets 201 is hinged together by the flexible hinges 202. The flexible hinges 202 are made of polyimide material, which can meet the bending requirements when the screen is rolled up. Connecting blocks 3 are fixedly connected to the outer walls of both the rigid sheets 201 and the flexible hinges 202. The connecting blocks 3 are made of ABS plastic and are fixed to the rigid sheets 201 and the flexible hinges 202 by hot-melt welding. The flexible display screen 1 is connected to the rigid support layer 2 by the connecting blocks 3. The end of the connecting block 3 away from the rigid support layer 2 is fixed to the back of the flexible display screen 1 by adhesive, so that the flexible display screen 1 and the rigid support layer 2 can move together.

[0026] The winding frame 4 is injection molded from ABS plastic, forming a rectangular frame structure to provide installation space for internal components. A winding mechanism is installed on the inner wall of the winding frame 4, comprising a fixed shaft 5, a winding drum 6, and a spring 7. The fixed shaft 5 is bolted to the upper and lower inner walls of the winding frame 4, ensuring stability during winding. The winding drum 6 is a hollow cylindrical structure with an inner diameter larger than that of the fixed shaft 5, and is rotatably connected to the outer wall of the fixed shaft 5. The length of the winding drum 6 is matched to the width of the rigid support layer 2. Springs 7 are installed in the inner cavity near both ends of the winding drum 6. Made of spring steel, one end of the spring is fixedly connected to the inner wall of the winding drum 6 by welding, and the other end is fixedly connected to the outer wall of the fixed shaft 5 by welding. When the screen is unfolded, the spring 7 is twisted and stores force. When the screen is released, the rebound force of the spring 7 can drive the winding drum 6 to rotate, realizing the automatic winding of the screen. One end of the flexible display screen 1 is fixedly set on the outer wall of the winding drum 6 by screws, and the other end passes through the winding frame 4 and is fixedly connected to an arc-shaped limiting plate 15. The arc-shaped limiting plate 15 is made of PVC material and can limit the screen when the screen is wound to the end, preventing the screen from completely entering the interior of the winding frame 4.

[0027] A limiting mechanism is installed on the outer wall of the arc-shaped limiting plate 15. The limiting mechanism includes a retaining strip 16 and a bearing seat 19. The bearing seat 19 is fixed to the outer wall of the arc-shaped limiting plate 15 by screws. One end of the retaining strip 16 is rotatably connected to the inner wall of the bearing seat 19 by a pin. A knob 20 is fixedly connected to one end of the pin. The knob 20 is made of rubber for easy operation by the user. The outer wall of the retaining strip 16 has multiple arc-shaped notches 17. The number of arc-shaped notches 17 matches the number of connecting blocks 3, and the size of the arc-shaped notches 17 matches the size of the connecting blocks 3. The multiple arc-shaped notches 17 and multiple connecting blocks 3 are matched and engaged. The top of the arc-shaped limiting plate 15 has an avoidance notch 18. The size of the avoidance notch 18 is slightly larger than the size of the retaining strip 16. The avoidance notch 18 corresponds to the retaining strip 16. When limiting is not required, the retaining strip 16 can be rotated outside the avoidance notch 18 to avoid interference with the screen.

[0028] Damping mechanisms are installed on the outer walls of both ends of the winding frame 4 to position the stretching length of the flexible display screen 1. The mechanisms include extrusion discs 10, damping beads 11, slide bars 12, connecting rings 13 and springs 14. The two extrusion discs 10 are located inside the two ends of the winding frame 4. The extrusion discs 10 are circular metal discs with a diameter that matches the internal width of the winding frame 4. Multiple damping beads 11 are made of rubber and are uniformly fixedly connected to the opposite outer walls of the two extrusion discs 10 in a circumferential array.

[0029] Multiple slide rods 12 are uniformly fixedly connected in a circumferential array to the outer wall of the extrusion disc 10 on the side opposite to the damping bead 11. The ends of the slide rods 12 away from the extrusion disc 10 pass through the winding frame 4 and are fixedly connected to a connecting ring 13. The connecting ring 13 is a metal ring, fixed to the slide rods 12 by welding. A compression spring 14 is sleeved on the outer wall of the slide rods 12 and located between the extrusion disc 10 and the winding frame 4. The spring constant of the spring 14 is greater than that of the spring-loaded spring 7. In its natural state, the spring 14 applies pressure to the extrusion disc 10, causing the damping bead 11 to be in close contact with the fixed disc 8.

[0030] Fixed discs 8 are fixedly connected to the upper and lower ends of the winding drum 6. The fixed discs 8 are circular metal discs and are fixedly connected to the winding drum 6 by welding. Multiple damping holes 9 are opened on the outer wall of the fixed discs 8. The diameter of the damping holes 9 is adapted to the diameter of the damping beads 11. The damping holes 9 and the damping beads 11 are matched and snapped together. A through hole is opened on the outer wall between the two fixed discs 8. The fixed discs 8 are rotatably connected to the fixed shaft 5 through the through hole.

[0031] The implementation principle of a retractable flexible-rigid composite structure screen in this application embodiment is as follows: When the screen needs to be unfolded, the user pulls the arc-shaped limiting plate 15, which drives the flexible display screen 1 and the rigid support layer 2 to be pulled out from the winding frame 4. At this time, the winding drum 6 rotates as the screen is pulled out, and the spring 7 is twisted and stored. During the pulling process, the fixed plate 8 rotates together with the winding drum 6. When it rotates to a certain angle, the damping bead 11 on the pressing plate 10 is stuck into the damping hole 9 on the fixed plate 8 under the pressure of the spring 14, which plays a damping role on the rotation of the winding drum 6, thereby realizing the positioning of the stretching length of the flexible display screen 1. When the stretching length needs to be adjusted, the arc-shaped limiting plate 15 is pulled or pushed to make the damping bead 11 disengage from the current damping hole 9 and enter the next damping hole 9 to complete the length adjustment.

[0032] When the screen is unfolded to the appropriate length and needs to be fixed, turn the knob 20 to rotate the locking strip 16, causing the arc-shaped notch 17 on the locking strip 16 to engage with the connecting block 3. This fixes the flexible display screen 1 and the rigid support layer 2 in the current position, preventing them from retracting under the action of the spring 7. At the same time, the rigid support layer 2 forms a whole under the engagement of the locking strip 16 and multiple connecting blocks 3. Since the connecting blocks 3 are fixed to the rigid sheet 201 and the flexible hinge 202 respectively, the locking strip 16 limits the connection block 3 through the arc-shaped notch 17, thus restricting the rotational freedom of the rigid sheet 201, which could originally rotate relative to the flexible hinge 202. The rigid support layer 2 will not easily bend or rotate, thereby forming a support for the flexible display screen 1. Stable support ensures that the flexible display screen 1 remains flat during use, guaranteeing the display effect. When the screen needs to be rolled up, the knob 20 is rotated in the opposite direction to disengage the arc notch 17 from the connecting block 3. The rigid sheet 201 of the rigid support layer 2 regains its relative rotational ability. Then, the two connecting rings 13 are pulled outward, which drives multiple slide rods 12 to move. The multiple slide rods 12 pull the two extrusion discs 10 to move in opposite directions against the elastic force of multiple springs 14, thereby causing the damping bead 11 to disengage from the damping hole 9 and releasing the positioning of the fixed disc 8. At this time, under the action of the spring spring 7, the winding drum 6 rotates, winding the flexible display screen 1 and the rigid support layer 2 onto the winding drum 6, completing the winding action.
