[0044] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0045] With the continuous innovation of technology, the display screen structure of electronic products is constantly being updated. After the folding screen, the pull-out display screen has become the development trend of the display screen of electronic equipment.

[0046] Since the screen of the pull-out display screen bends around the scroll, the rotation of the scroll drives the screen to unfold or curl. Therefore, the scroll structure is crucial and affects the overall function and use effect of the pull-out display screen.

[0047] In related technology, the screen of a pull-out display is U-shaped, using movable pulleys to support the screen during its unfolding and curling. This structure occupies a significant amount of space inside the electronic device when the curled screen is stored, seriously affecting the overall internal layout of electronic devices such as mobile phones and tablets. Furthermore, the need to reserve space for the curled portion of the screen results in a generally smaller battery capacity for pull-out displays.

[0048] In addition, the pull-out display screen with the above structure has a U-shaped folding structure. Even in the unfolded state, the unfolded screen area cannot be greater than twice the screen area in the rolled state, and the demand for further expansion of the screen area in the unfolded state cannot be met.

[0049] In order to solve the above problems, the present disclosure provides a display screen structure, which includes a rotating shaft. The rotating shaft rotates forward or reversely, and the curling area of the flexible screen of the display screen structure is wound around the rotating shaft or is in an unfolded state, thereby reducing the occupation of the curling area by the internal space of the electronic device; at the same time, since the curling area is wound around the rotating shaft, more flexible screens can be wrapped around it, so that the display screen structure can obtain a larger screen unfold when it is in the unfolded state, thereby improving the user experience.

[0050] According to an exemplary embodiment, Figure 1 As shown, the present disclosure provides a display screen structure comprising a fixed portion 100 and an unfolding portion 200 movable relative to the fixed portion 100. Under a first external force, such as a user manually pulling the unfolding portion 200, the unfolding portion 200 moves away from the fixed portion 100, and the display screen structure displays in an unfolded state. Under a second external force, such as a user manually pushing the unfolding portion 200, the unfolding portion 200 moves toward the fixed portion 100, and the display screen structure changes from the unfolded state to the contracted state, which can also be considered a folded state.

[0051] In this embodiment, the unfolding portion 200 includes a rotating shaft 230, and the display screen structure further includes a flexible screen 300 (see Figure 2 ), the first side of the flexible screen 300 is fixedly connected to the fixing portion 100, and the second side of the flexible screen 300 is connected to the rotating shaft 230. The first side and the second side are opposite to each other, and the first side and the second side are respectively two opposite sides of the flexible screen 300 in its width direction. Among them, the second side of the flexible screen 300 is fixedly connected to the rotating shaft 230, for example, by bonding or other means. The rotating shaft 230 can rotate forward or reverse under the action of an external force to drive the curling area 310 of the flexible screen 300 (refer to Figure 2 ) is wound around the rotating shaft 230 or is in an unfolded state.

[0052] The display screen structure also includes a housing 400. In addition to housing components such as the hinge 230, the housing 400 also accommodates the main components of the display screen structure, such as a battery and a motherboard. The housing 400 comprises a fixed housing 410, which is part of the fixed portion 100, and an unfolding housing 420, which is part of the unfolding portion 200. A first side of the flexible screen 300 is fixedly connected to the fixed housing 410. Structures of the fixed housing 410 located below the flexible screen 300 support the flexible screen 300. The unfolding housing 420 of the unfolding portion 200 forms a housing space within which the hinge 230 is mounted. A space is provided between the hinge 230 and the inner wall of the unfolding housing 420 to accommodate the curling region 310 of the flexible screen 300 when it is rolled up around the hinge 230. Because the curling region 310 is wrapped around the hinge 230, the display area of the display screen structure in its unfolded state can be twice that of its collapsed state, enhancing the user experience.

[0053] The display screen structure in this embodiment also includes a sliding assembly 500, which includes a first-step rail 510 disposed on the fixed portion 100 and a sliding rail 520 disposed on the unfolding portion 200. The sliding rail 520 slides relative to the first-step rail 510. When the display screen structure is in a folded state, at least a portion of the sliding rail 520 is concealed within the first-step rail 510. The flexible screen 300 includes a fixed area 320 and a rollable area 310. Whether the display screen structure is in a folded state or in an unfolded state, the fixed area 320 is always used for display. When the display screen structure is in a folded state, the rollable area 310 is not used for display; when the display screen structure is in an unfolded state, the rollable area 310 is stretched and unfolded for display.

[0054] When the display screen structure is in a collapsed state, the sliding rail 520 can be hidden within the first-stage rail 510, reducing the overall size of the display screen structure. When the display screen structure is in an expanded state, the sliding rail 520 slides out from the first-stage rail 510 to increase the overall size of the display screen structure, thereby increasing the display area. Users can switch between small and large display sizes according to their needs, improving user flexibility.

[0055] According to an exemplary embodiment, Figures 2 to 9 As shown, the display screen structure in this embodiment includes a fixed portion 100 and an unfolding portion 200 that moves relative to the fixed portion 100. The unfolding portion 200 includes a pull-out portion 210 and at least one connecting portion 220, with the at least one connecting portion 220 being connected to the pull-out portion 210 and the fixed portion 100, respectively. By providing at least one connecting portion 220, the unfolding area of the display screen structure can be further increased. At the same time, the connecting portion 220 can also provide effective support for the flexible screen 300 when the display screen structure is in the unfolded state.

[0056] like Figure 2 and Figure 3 As shown, the unfolding portion 200 in this embodiment includes a drawer portion 210 and a connecting portion 220. The connecting portion 220 connects the drawer portion 210 and the fixed portion 100, respectively. Both the connecting portion 220 and the drawer portion 210 are movable relative to the fixed portion 100. The drawer portion 210 includes an unfolding housing 420. The rotating shaft 230 of the unfolding portion 200 is disposed in the unfolding housing 420 of the drawer portion 210. Of course, it is understood that the number of connecting portions 220 can be more than one, such as two or three. When the width dimension of the connecting portion 220 remains unchanged, increasing the number of connecting portions 220 can increase the display area of the display screen structure in the unfolded state. When the unfolding portion 200 includes multiple connecting portions 220, for example, it includes three connecting portions 220 connected in sequence, a first connecting portion, a second connecting portion and a third connecting portion (the above three connecting portions are not shown in the figure), the first connecting portion is connected to the fixing portion 100, the second connecting portion is connected to the first connecting portion, the third connecting portion is connected to the second connecting portion, and the third connecting portion is connected to the pulling portion 210.

[0057] The display screen structure in this embodiment further includes a sliding component 500, such as Figure 4 and Figure 6 As shown, the sliding assembly 500 is disposed on the upper and / or lower side of the flexible screen 300. In this embodiment, the upper and lower sides refer to the upper and lower sides in the length direction of the display structure. The sliding assembly 500 can be disposed only on the upper side of the flexible screen 300, or only on the lower side of the flexible screen 300. Preferably, the sliding assembly 500 is disposed on both the upper and lower sides of the flexible screen 300 to provide sufficient power during the expansion and contraction of the flexible screen 300, thereby improving sliding reliability and stability.

[0058] The sliding assembly 500 includes a first-stage rail 510 and a sliding rail 520 disposed on the fixed portion 100. The sliding rail 520 includes a final-stage rail 530 disposed on the drawer portion 210 and a connecting rail assembly disposed on at least one connecting portion 220. The connecting rail assembly is respectively connected to the first-stage rail 510 and the final-stage rail 530. Each connecting portion 220 is provided with a connecting rail 540. Adjacent connecting rails 540 are connected, and at least one connecting rail 540 constitutes a connecting rail assembly.

[0059] In one example, if Figures 2 to 9As shown, the unfolding portion 200 of this example includes a connecting portion 220, and the connecting rail assembly includes only one connecting rail 540. The connecting rail 540 is connected to the first-step rail 510 and the last-step rail 530, respectively. Both the last-step rail 530 and the connecting rail 540 are capable of moving relative to the first-step rail 510. The first-step rail 510 and the connecting rail 540 each include a cavity. When the display screen structure is in a tightened state, part of the last-step rail 530 is accommodated in the cavity of the connecting rail 540, and part of the connecting rail 540 is accommodated in the cavity of the first-step rail 510, thereby reducing the overall volume of the display screen structure.

[0060] In this example, the final-step rail 530 is provided with a final-step body 531 and a final-step rib 532, while the connecting rail 540 is provided with a connecting body 541 and a connecting rib 542. The final-step rib 532 and the connecting rib 542 are staggered in the thickness direction of the flexible screen 300. When the display screen structure is in a tightened state, the final-step body 531 is accommodated in the cavity of the connecting rail 540, and the outer surface of the final-step rib 532 is flush with the outer surface of the connecting rail 540. The connecting body 541 is accommodated in the cavity of the first-step rail 510, and the outer surface of the connecting rib 542 is flush with the outer surface of the first-step rail 510, thereby preventing interference between the first-step rail 510, the final-step rail 530, and the connecting rail 540. The fixing portion 100 in this example further includes a fixing portion body 110 and a side cover 120 . The side cover 120 is mounted on the fixing portion body 110 to shield the sliding rail 520 when the display screen structure is in a tightened state.

[0061] In another example (this example is not shown in the figure), the unfolding portion of this example includes two first connecting portions and a second connecting portion connected in sequence, the first connecting portion includes a first slide rail and the second connecting portion includes a second slide rail, and the first slide rail and the second slide rail together constitute a connecting slide rail group. The first-step slide rail is connected to the first slide rail, the first slide rail is connected to the second slide rail, and the second slide rail is connected to the last-step slide rail. The first-step slide rail, the first slide rail, the second slide rail and the last-step slide rail all include cavities. When the display screen structure is in a tightened state, part of the structure of the last-step slide rail is accommodated in the cavity of the second slide rail, part of the structure of the second slide rail is accommodated in the cavity of the first slide rail, and part of the structure of the first slide rail is accommodated in the cavity of the first-step slide rail, so as to reduce the volume of the display screen structure as a whole.

[0062] The display screen structure in this embodiment also includes a step pulley 600, a pull line 610 and a plurality of pulleys 800. The step pulley 600 is arranged in the pull-out portion 210. Specifically, the step pulley 600 is arranged at the end of the rotating shaft 230, and the step pulley 600 is provided with a spiral groove. The interior of the rotating shaft 230 is provided with a rotary motor 900. The rotary motor 900 includes a body and an output shaft. The output shaft of the rotary motor 900 is fixedly connected to the pull-out portion 210. The body of the rotary motor 900 is connected to the rotating shaft 230, driving the rotating shaft 230 and the step pulley 600 to rotate together. In this embodiment, the transfer motor 900 is reversely utilized so that the output shaft of the rotary motor 900 is fixedly connected to the pull-out portion 210, limiting the rotation of the output shaft of the rotary motor 900. At the same time, the body of the rotary motor 900 is fixedly connected to the rotating shaft 230, outputting torque to the rotating shaft through the body, driving the rotating shaft 230 to rotate. Since the step pulley 600 is fixed to the end of the rotating shaft 230 and is coaxially arranged with the rotating shaft 230 , when the rotating shaft 230 rotates, the step pulley 600 is driven to rotate around the axis of the rotating shaft 230 at the same time.

[0063] like Figure 4 As shown, multiple pulleys 800 are respectively arranged on the last-step slide rail 530, the connecting slide rail 540 and the first-step slide rail 510. One end of the pull wire 610 is fixed to the first-step slide rail 510. The pull wire 610 is sequentially wound around the multiple pulleys 800, and the other end of the pull wire 610 is wound around the step pulley 600. The pull wire 610 is wound in the spiral groove and is always in a tensioned state.

[0064] In one example, a plurality of pulleys 800 are respectively disposed on the last-step rib 532 of the last-step rail 530, the connecting rib 542 of the connecting rail 540, and the first-step rib 511 of the first-step rail 510. Two pulleys 800 are disposed on the last-step rib 532, two pulleys 800 are disposed on the connecting rib 542, and one pulley 800 is disposed on the first-step rib 511. The two pulleys 800 on the last-step rib 532 are staggered vertically along the thickness direction of the flexible screen 300, the two pulleys 800 on the connecting rib 542 are staggered offline, and the pulley 800 on the first-step rib 511 is disposed at an end of the fixing portion 100 away from the edge.

[0065] In another example (not shown), multiple pulleys are provided on the final rib of the final rail and on the connecting rib that connects the rails. Two pulleys are provided on the final rib, and three pulleys are provided on the connecting rib. The two pulleys on the final rib are staggered vertically along the thickness of the flexible screen. Two of the three pulleys on the connecting rib are co-located, and the other pulley is staggered relative to the first two pulleys.

[0066] The cable is fixed on a pulley on the first-step rib, and is then wound around a pulley on the connecting rib, then a pulley on the last-step rib. Finally, the other end of the cable is wound around a step pulley and fixedly connected to the step pulley. The cable can be fixed to the step pulley by gluing or by attaching a buckle to the step pulley, so that the cable is wound in the spiral groove and is always in a tensioned state.

[0067] In this embodiment, a multi-stage slide rail, a step pulley 600, and a cable 610 are provided. The cable 610 is spirally wound around the step pulley 600. When the display screen structure transitions from a taut state to an extended state, the multi-stage slide rails gradually separate, and the cable 610 wound around the step pulley 600 gradually extends outward, while the cable 610 remains in a tensioned state. When the display screen structure transitions from an extended state to a taut state, the multi-stage slide rails gradually retract, and the cable 610 spirally wound around the step pulley 600 remains in a tensioned state, thereby enabling the display screen structure to stably expand and contract across its width.

[0068] At the same time, due to the provision of the tower pulley 600 and the pull wire 610, the pull wire 610 is spirally wound on the tower pulley 600. Even if the rotating motor 900 is in the power-off state, when the pulling part 210 is subjected to the pushing pressure applied by the user and moves toward the fixed part 100 to tighten the flexible screen 300, the pulling part 210 will not shrink quickly and collide with the fixed part 100. Instead, under the action of the pull wire 610 and the tower pulley 600 in the tensioned state, it slowly moves toward the fixed part 100, thereby realizing manual opening and closing in the power-off state, and also improving the telescopic stability and reliability of the pulling part 210 of the display screen structure during movement, and the screen is less likely to have obvious creases.

[0069] like Figure 2 and Figure 6As shown, the fixing portion 100 in this embodiment includes a first support group 130, the at least one connecting portion 220 includes at least one second support group 250, and the pull-out portion 210 includes a third support group 240. The first support group 130, the at least one second support group 250, and the third support group 240 are located in the same plane and together constitute a support portion for supporting the flexible screen 300. The following describes the implementation of this embodiment using only one second support group 250 as an example. Along the length of the flexible screen 300, the first support group 130 includes multiple first support ribs 131 arranged side by side, each second support group 250 includes multiple second support ribs 231 arranged side by side, and the third support group 240 includes multiple third support ribs 241 arranged side by side. To ensure seamless splicing of the first, second, and third support ribs 231, the length of the third support ribs 241 along the width of the flexible screen 300 is greater than that of the second support ribs 231. The distance between two adjacent first support ribs 131, the area between two adjacent second support ribs 231, and the distance between two connected third support ribs 241 are basically the same, which not only facilitates production and processing but also improves support reliability.

[0070] When the display screen structure is in the tightened state, the first support ribs 131, the second support ribs 231, and the third support ribs 241 are arranged side by side to form a support unit. Multiple support units are arranged side by side along the length of the flexible screen 300 to form a support surface. In addition to the first support ribs 131, the first support group 130 of the fixing portion 100 also includes an auxiliary surface 132. In the tightened state, the second support ribs 231 and the third support ribs 241 are located above the auxiliary surface 132.

[0071] When the display screen structure is in the unfolded state, the first support ribs 131, the at least one second support rib 231, and the third support ribs 241 are staggered. The first support ribs 131, the second support ribs 231, and the third support ribs 241 support the flexible screen 300 in different areas across the width of the display screen structure, ensuring that the flexible screen 300 is flat after unfolding.

[0072] The display screen structure in this embodiment further includes a stabilizing component 700, such as Figures 2 to 9 As shown, the stabilizing assembly 700 is disposed between the pull-out portion 210 and the connecting portion 220, and between the connecting portion 220 and the fixing portion 100, respectively, to enhance the stability of the display screen mechanism during movement of the pull-out portion 210 relative to the fixing portion 100. Along the thickness direction of the display screen structure, the stabilizing assembly 700 is disposed on the underside of the flexible screen 300, providing a certain degree of support for the various supporting assemblies located above it, further enhancing the reliability of the display screen mechanism.

[0073] When the drawer portion 210 moves relative to the fixed portion 100, the stabilizing assembly 700 applies a force opposite to the direction of movement to the drawer portion 210, the connecting portion 220, and / or the fixed portion 100. The stabilizing assembly 700 includes two cross-connecting rods 710, which are hingedly connected so that when an external force is applied, the two connecting rods 710 rotate relative to each other, changing the angle between adjacent drawers 210 and connecting portions 220, between adjacent connecting portions 220, or between a connecting portion 220 and the fixed portion 100 as the distance increases or decreases.

[0074] Any two of the drawing-out portion 210, the connecting portion 220 and the fixed portion 100 form one group of mobile group, one of the any two as the first mobile member of the mobile group, and another of the any two as the second mobile member of the mobile group. For example, the drawing-out portion 210 and the connecting portion 220 form a mobile group, and in this mobile group, the drawing-out portion 210 is as the first mobile member, and the connecting portion 220 is as the second mobile member.
