Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a sliding mechanism and a sliding display device. Background Art

[0002] Compared with traditional display screens, flexible screens have significant advantages such as bendability, flexibility, and light weight. They are currently a type of display screen that has received widespread attention in the field. As a new form of flexible screen, the sliding roll form can significantly reduce the volume of the terminal product while expanding the display area of ​​the screen. In current sliding roll display devices, the flexible screen is usually rolled up on a reel, and the display area of ​​the flexible screen is changed by stretching and rolling up. However, when the flexible screen is stretched outward, the area where the flexible screen is curled on the reel will experience local bulges and other warping deformations, which will affect the flatness of the display and reduce the display quality of the display. Summary of the invention

[0003] Based on this, it is necessary to provide a sliding mechanism and a sliding display device to improve the flatness of the flexible screen so that it has a higher display quality.

[0004] According to one aspect of the present application, a sliding and rolling mechanism is provided for a flexible screen, and the sliding and rolling mechanism includes:

[0005] A main frame and a frame, wherein the frame is slidably connected to the main frame along a first direction;

[0006] A sliding scroll is connected to the frame and rotates around an axis. The flexible screen can be wound around the sliding scroll, and one end of the sliding scroll is connected to the main frame. The sliding scroll is configured to move closer to or farther from the main frame along a first direction under the drive of the frame, so as to roll up or unfold the flexible screen.

[0007] A pushing member is arranged on the frame; and a driving assembly is connected to the pushing member so as to drive the pushing member to push the side of the flexible screen away from the sliding scroll when the sliding scroll moves away from the main frame along the first direction.

[0008] In the above-mentioned sliding mechanism, the sliding reel is connected to the frame by rotating around an axis, and the frame is connected to the main frame by sliding along the first direction, so that when the frame slides relative to the main frame along the first direction, the sliding reel is driven to slide relative to the main frame along the first direction. Since the flexible screen is wound on the sliding reel and one end is connected to the main frame, when the sliding reel moves closer to the main frame along the first direction, the flexible screen can be rolled up, and when the sliding reel moves away from the main frame along the first direction, the flexible screen can be unfolded.

[0009] In addition, the sliding mechanism is also provided with a pushing piece and a driving component. When the sliding scroll moves away from the main frame along the first direction, the driving component can drive the pushing piece to push the side of the flexible screen away from the sliding scroll, that is, drive the pushing piece to press against the surface of the flexible screen away from the sliding scroll, and push the flexible screen to move toward the sliding scroll. In this way, when the sliding scroll moves away from the main frame along the first direction and drives the flexible screen to unfold, even if the local position of the flexible screen tends to be deformed due to the force, it will not be bulged or other warping deformations due to the obstruction of the pushing piece, thereby improving the flatness of the flexible screen and the display quality of the flexible screen.

The second transmission component is configured to drive the pushing member to extend along the first direction when the first transmission member drives the pushing member to move closer to the sliding shaft.

[0022] In some embodiments, the second transmission assembly includes:

[0023] A second transmission member is slidably connected to the pushing member along the first direction;

[0024] The gear is arranged on the pushing member and meshes with both the first transmission member and the second transmission member. The gear is configured to drive the second transmission member to slide along the first direction when the first transmission member drives the pushing member to move toward the sliding reel, so as to drive the pushing member to extend along the first direction.

[0025] In some embodiments, the second transmission member is configured as a rack and is capable of moving along its own length direction when the gear rotates.

[0026] In some embodiments, the number of the first transmission members is two, and the two first transmission members are respectively located on both sides of the second transmission member in the axial direction of the gear to mesh with different positions in the axial direction of the gear.

For example, "approximately", "approximately" or "substantially" can mean within one or more standard deviations, which are not limited here.

[0064] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0065] With the development of science and technology, flexible display screens have gradually entered the field of vision of consumers, and the rollability of the screen has greatly expanded its application in the display field. Compared with traditional screens, flexible screens have obvious advantages. Not only are they thinner and lighter in size, but their power consumption is also lower than that of traditional devices, which helps to improve the battery life of the device. At the same time, based on the characteristics of bendability and good flexibility, a sliding and rolling method can generally be adopted when used in a display device. The area of ​​the display area can be adjusted, and it can be rolled up when not in use, which is convenient for storage and saves space. In the current sliding display device, the flexible screen body is usually rolled up on a reel, and the display area of ​​the flexible screen is changed by stretching and rolling. However, after long-term research, the inventors found that when the flexible screen is stretched outward, the area of ​​the flexible screen corresponding to the reel is prone to warping, especially in the final state of the stretching operation, where this warping deformation is most obvious.

[0066] In response to the above problems, the embodiments of the present application propose a sliding mechanism and a sliding display device, in which a pushing piece is arranged at the position of the sliding axis corresponding to the display side of the flexible screen away from the sliding axis. When the flexible screen is unfolded, the pushing piece pushes the flexible screen toward the sliding axis to improve the problem of local warping of the flexible screen during the sliding process.

[0067] The following is a description of the scroll mechanism and the scroll display device of the embodiment of the present application in conjunction with the accompanying drawings. In the embodiment of the present application, for the convenience of description, the direction in which the scroll shaft 30 approaches or moves away from the main frame 10 is defined as a first direction F, and the direction perpendicular to both the first direction F and the axial direction O of the scroll shaft 30 is defined as a second direction H; wherein the first direction F is also the unfolding direction of the flexible screen body 20 relative to the main frame 10.

[0068] Figure 1 This is a structural diagram of a sliding and rolling mechanism provided in an embodiment of the present application. Figure 2 for Figure 1 Top view of the .

[0069] Reference Figure 1 , Figure 2 The sliding mechanism 100 provided in the embodiment of the present application is used for the flexible screen 20. The sliding mechanism 100 includes: a main frame 10 and a frame 40, the frame 40 is slidably connected to the main frame 10 along a first direction F; a sliding scroll 30, which is rotatably connected to the frame 40 around an axis, the flexible screen 20 can be wound around the sliding scroll 30, and one end is connected to the main frame 10, the sliding scroll 30 is configured to be able to move closer to or away from the main frame 10 along the first direction F under the drive of the frame 40, so that the flexible screen 20 can be rolled up or unfolded; a pushing member 50, which is arranged on the frame 40; and a driving component 60, which is connected to the pushing member 50, so that when the sliding scroll 30 moves away from the main frame 10 along the first direction F, it can drive the pushing member 50 to push the side of the flexible screen 20 away from the sliding scroll 30.

[0070] In the above scheme, the sliding scroll 30 is rotatably connected to the frame 40, and the frame 40 is slidably connected to the main frame 10 along the first direction F, so that when the frame 40 slides relative to the main frame 10 along the first direction F, the sliding scroll 30 is driven to slide relative to the main frame 10 along the first direction F. Since the flexible screen 20 is wound on the sliding scroll 30, and one end is connected to the main frame 10, when the sliding scroll 30 moves closer to the main frame 10 along the first direction F, the flexible screen 20 can be rolled up, and when the sliding scroll 30 moves away from the main frame 10 along the first direction F, the flexible screen 20 can be unfolded.

[0071] In addition, the sliding mechanism 100 is further provided with a pushing member 50 and a driving assembly 60. When the sliding reel 30 moves away from the main frame 10 along the first direction F, the driving assembly 60 can drive the pushing member 50 to push the side of the flexible screen 20 away from the sliding reel 30, that is, drive the pushing member 50 to press against the surface of the flexible screen 20 away from the sliding reel 30, and push the flexible screen 20 to move closer to the sliding reel 30. In this way, when the sliding reel 30 moves away from the main frame 10 along the first direction F and drives the flexible screen 20 to unfold, even if a local position of the flexible screen 20 tends to be deformed due to force, it will not be warped or deformed due to the obstruction of the pushing member 50, thereby improving the flatness of the flexible screen 20 and improving the display quality of the flexible screen 20.

[0072] In the embodiment of the present application, the frame 40 is slidably connected to the main frame 10 along the first direction F, which means that the frame 40 and the main frame 10 are directly or indirectly connected, and the frame 40 can slide closer to or farther away from the main frame 10 along the first direction F.

[0073] Exemplarily, the frame 40 is provided with a first matching portion 45, and the main frame 10 is provided with a second matching portion 11, and the first matching portion 45 and the second matching portion 11 are guided and matched along the first direction F, so that the frame 40 is slidably connected to the main frame 10 along the first direction F. In this way, the frame 40 and the main frame 10 can be guided and matched along the first direction F through the first matching portion 45 and the second matching portion 11, and when the frame 40 is subjected to external force, for example, when the flexible screen 20 is rolled up under the operation of the user, the sliding operation can be made more stable.

[0074] In addition, it can be understood that in the embodiment of the present application, the frame 40 and the main frame 10 can be independently provided and may not contact each other during the sliding process.

[0075] The guiding cooperation of the first matching portion 45 and the second matching portion 11 can be, for example, that one of the first matching portion 45 and the second matching portion 11 has a guide rail inside, the guide rail extends along the first direction F, and the other is configured as a slider, and the slider is inserted into the guide rail to achieve the guiding cooperation of the two. Of course, the present application is not limited to this, and other guiding cooperation methods can also be used, which will not be repeated here.

[0076] In the embodiment of the present application, the sliding scroll 30 is connected to the frame 40 by rotating around an axis. In a specific implementation, for example, the sliding scroll 30 can be connected to the frame 40 by rotating around its own axis. In this way, the sliding scroll 30 moves under the drive of the frame 40, and during the unfolding or reeling process of the flexible screen 20, it can rotate synchronously with the unfolding or reeling of the flexible screen 20, thereby reducing the relative friction between the flexible screen 20 and the sliding scroll 30, making the sliding and reeling process smoother.

[0077] Continue to refer to Figure 1As mentioned above, the flexible screen body 20 is wound on the outer circumference of the sliding and rolling shaft 30, and the flexible screen body 20 can be connected to the first end 21 of the main frame 10. The flexible screen body 20 also includes a second end 22 away from the first end 21. The sliding and rolling mechanism 100 also includes a pulling component 70 disposed on the main frame 10; the pulling component 70 is configured to be connected to the second end 22 to provide a pulling force to tighten the flexible screen body 20. In other words, the pulling component 70 provides a pulling force to the second end 22 of the flexible screen body 20, so that the rolled-up part of the flexible screen body 20 is always in a straight shape. Under the action of the pulling force, the flexible screen body 20 can maintain a flat state whether it is converted from a rolled-up state to an unfolded state, or from an unfolded state to a rolled-up state, to prevent the flexible screen body 20 from wrinkling.

[0078] In the present application, continue to refer to Figure 1 The driving assembly 60 includes a driving member (not shown) and a first transmission member 61. The driving member is connected to the sliding scroll 30 and is configured to drive the sliding scroll 30 to rotate around its own axis when the sliding scroll 30 moves along the first direction F. The first transmission member 61 is fixedly connected to the push member 50 and meshes with the sliding scroll 30. The first transmission member 61 is configured to be able to drive the push member 50 to move closer to the sliding scroll 30 when the sliding scroll 30 rotates and moves away from the main frame 10 along the first direction F, so that the push member 50 pushes the side of the flexible screen 20 away from the sliding scroll 30. By setting the driving member, the sliding scroll 30 can be reliably rotated during the sliding process of the flexible screen 20, and because the first transmission member 61 meshes with the sliding scroll 30, when the sliding scroll 30 rotates, the first transmission member 61 can drive the push member 50 connected thereto to move closer to the sliding scroll 30 under the drive of the sliding scroll 30.

[0079] In the embodiment of the present application, the driving assembly 60 is further configured to drive the pushing member 50 away from the side of the flexible screen 20 that is away from the sliding scroll 30 when the sliding scroll 30 rotates and moves toward the main frame 10 along the first direction F. In this way, when the sliding scroll 30 approaches the main frame 10 to reel the flexible screen 20, the driving assembly 60 can drive the pushing member 50 connected thereto to move in a direction away from the sliding scroll 30 under the drive of the sliding scroll 30.

[0080] In combination with the above-mentioned pushing action, when the flexible screen body 20 is unfolded, the pushing piece 50 moves toward the direction close to the flexible screen body 20, pushing the position where warping deformation such as bulge is about to occur, and when the flexible screen body 20 is rolled up, the pushing piece 50 moves away from the flexible screen body 20, avoiding interference with the flexible screen body 20 and reducing friction with the flexible screen body 20, so that the rolling process is smoother and more fluent.

[0081] Specifically, in the first transmission member 61 , the first transmission member 61 is also configured to drive the pushing member 50 to move away from the sliding reel 30 when the sliding reel 30 rotates.

[0082] As for the meshing cooperation between the first transmission member 61 and the sliding reel 30, Figure 1 and Figure 2 As a possible implementation, the shaft section on the sliding reel 30 that meshes with the first transmission member 61 is constructed as a first gear shaft section 31, and the first transmission member 61 is configured as a rack and can move along its own length direction when the sliding reel 30 rotates. The length direction of the rack can be arranged along the second direction H, and the outer peripheral surface of the first gear shaft section 31 is provided with teeth meshing with the rack. In this way, when the sliding reel 30 rotates, the first transmission member 61 can move along the second direction H driven by the teeth on the sliding reel 30, and the pushing member 50 connected to the first transmission member 61 can also move along the second direction H.

[0083] When implementing it, refer to Figure 1 The sliding reel 30 moves along the first direction F. Figure 1 When the flexible screen 20 is unfolded when the left side moves as shown in the figure, the sliding scroll 30 is driven to rotate in the counterclockwise direction, and the first gear shaft section 31 drives the first transmission member 61 to rotate along the second direction H. Figure 1 The push member 50 moves downward in the drawing, and driven by the first transmission member 61, the push member 50 also moves in the second direction H. Figure 1 The flexible screen 20 moves downward from the drawing, thereby pushing the side of the flexible screen 20 away from the sliding scroll 30 to prevent the flexible screen 20 from partially bulging or warping. Figure 1 When the right side moves as shown in the figure, the flexible screen body 20 is rolled up, driving the sliding scroll shaft 30 to rotate in the clockwise direction, and the first gear shaft section 31 drives the first transmission member 61 to move along the second direction H. Figure 1 The push member 50 moves upward in the figure, and driven by the first transmission member 61, the push member 50 also moves along the second direction H toward Figure 1 The push member 50 moves above the drawing, thereby moving away from the side of the flexible screen body 20 that is away from the sliding reel 30, reducing the friction between the push member 50 and the flexible screen body 20, so that the flexible screen body 20 is smoother during the reeling process.

[0084] Further, see Figure 2 In order to make the cooperation between the first transmission member 61 and the sliding scroll 30 more stable, the number of the first transmission members 61 can be two, and each first transmission member 61 is correspondingly provided with a first gear shaft segment 31, that is, the sliding scroll 30 includes two first gear shaft segments 31, and the two first gear shaft segments 31 are respectively matched with the two first transmission members 61 one by one.

[0085] The sliding reel 30 also includes a winding section 32 for winding the flexible screen 20, and the winding section 32 is located between the two first gear shaft sections 31 corresponding to the two first transmission members 61. The two first transmission members 61 are located on both sides of the flexible screen 20 along the axis direction O (hereinafter also referred to as the axis direction O) of the sliding reel 30, so that the winding of the flexible screen 20 and the meshing cooperation of the first transmission members 61 can be prevented from affecting each other.

[0086] It is understandable that the meshing cooperation between the sliding scroll 30 and the first transmission member 61 described herein includes but is not limited to the above-mentioned gear rack meshing cooperation, for example, it can also be other types of meshing cooperation such as worm gear cooperation. Specifically, the shaft section on the sliding scroll 30 that meshes with the first transmission member 61 is constructed as a worm gear section, and the first transmission member 61 is configured with a worm that is threadedly engaged with the worm gear section, and can move along its own length direction when the sliding scroll 30 rotates. It should be noted that in the case where the meshing cooperation between the sliding scroll 30 and the first transmission member 61 is of other structural forms, the setting of the relative position of the first transmission member 61 and the flexible screen body 20 is similar to this, and will not be repeated here.

[0087] Furthermore, the driving member may be, for example, a motor, and the motor shaft of the motor may be in transmission connection with the sliding reel 30, so that the motor drives the sliding reel 30 to rotate. Figure 1 Exemplarily, a clamping portion 611 may be provided on the first transmission member 61 , and the clamping portion 611 is clamped to the pushing member 50 , so that the first transmission member 61 is connected to the pushing member 50 .

[0088] In the embodiment of the present application, as mentioned above, the push member 50 is arranged on the frame 40, and the push member 50 and the sliding scroll 30 are arranged relative to each other in the second direction H. Such a setting position can effectively avoid the warping deformation such as bulging of the flexible screen body 20. This is because the position on the flexible screen body 20 corresponding to the sliding scroll 30 is the part most likely to undergo warping deformation such as bulging, and the push member 50 and the sliding scroll 30 are arranged relative to each other in the second direction H, so that the part on the flexible screen body 20 most likely to undergo deformation is located between the push member 50 and the sliding scroll 30, so that when the push member 50 pushes the side of the flexible screen body 20 away from the sliding scroll 30, the part most likely to undergo deformation can be effectively pushed.

[0089] Figure 3 This is a schematic diagram of the structure of the push member and the frame in the sliding mechanism provided in an embodiment of the present application. Figure 4 for Figure 3 Left section view of . Figure 5 This is a schematic diagram of another structure in which a push member and a frame cooperate in a sliding mechanism provided in an embodiment of the present application. Figure 6A schematic diagram of another structure in which a push member and a frame cooperate in a sliding mechanism provided in an embodiment of the present application.

[0090] In the present application, refer to Figure 3 , Figure 4 The push member 50 can be slidably connected to the frame 40 along the second direction H. Here, in order to make the push member 50 move toward the sliding scroll 30 more smoothly, it can be considered to guide the push member 50 and the frame 40. In specific implementation, the push member 50 is provided with a guide portion 54, and the frame 40 is configured with a guide rail 41 matching the guide portion 54, and the guide portion 54 can be guided along the second direction H and matched with the guide rail 41.

[0091] Furthermore, at least one end of the pushing member 50 along the second direction H is provided with an elastic member 42, and the elastic member 42 may be located between the pushing member 50 and the frame 40, and the elastic member 42 is configured to apply an elastic force in the opposite direction of its movement to the guide portion 54. It is understandable that when the sliding reel 30 drives the first transmission member 61 to reciprocate along the second direction H, it is possible that the first transmission member 61 and the two ends of the guide rail 41 in the second direction H may collide with each other, and by providing the elastic member 42, the elastic member 42, on the one hand, applies an elastic force in the opposite direction of its movement to the guide portion 54, supports the guide portion 54, and slows down the impact speed, and on the other hand, can absorb the impact energy, and can reduce the noise caused by the impact of the guide rail 41 and the guide portion 54.

[0092] For the specific structure of the guide portion 54 and the guide rail 41, refer to Figure 3 and Figure 4 As a possible implementation, the frame 40 includes a bottom wall 46 and two side walls 47 disposed on the bottom wall 46, the two side walls 47 are disposed opposite to each other and spaced apart in the axial direction O, the aforementioned guide rail 41 includes two first guide rails 411, the two first guide rails 411 are respectively provided on the surfaces of the two side walls 47 that are opposite to each other, the guide portion 54 includes a base 540 disposed on the push member 50, and two first guide portions 541 extending from the two ends of the base 540 along the axial direction O, the base 540 is inserted between the two side walls 47, and the two first guide portions 541 are respectively guided and matched with one first guide rail 411. Such an arrangement makes it difficult for the guide portion 54 to fall out of the guide rail 41.

[0093] Reference Figure 5As another possible implementation, the guide portion 54 includes a second guide portion 542 extending from the two ends of the push member 50 in the axial direction O, and the second guide portion 542 is also located at the end of the push member 50 in the first direction F. A first frame accommodating cavity 48 with an opening is constructed in the frame 40, and at least part of the structure of the push member 50 is located in the first frame accommodating cavity 48. The guide rail 41 is provided with two second guide rails 412 corresponding to the two second guide portions 542, and a protrusion 481 is protruded on two opposite cavity walls of the first frame accommodating cavity 48. Two second guide rails 412 are defined between the two protrusions 481 and the cavity bottom wall of the first frame accommodating cavity 48, and the two second guide portions 542 are respectively guided and matched with the two second guide rails 412. In such a setting, the frame 40 can protect the structure of the push member 50 at the two ends in the axial direction O.

[0094] Reference Figure 6 As another possible implementation, the guide portion 54 includes a third guide portion 543 extending from two ends of the push member 50 along the axial direction O. The frame 40 is configured with a second frame accommodating cavity 49 having an opening, and at least part of the structure of the push member 50 is located in the second frame accommodating cavity 49. The guide rail 41 is provided with two third guide rails 413 corresponding to the two third guide portions 543, respectively. The two third guide rails 413 are respectively opened on two opposite cavity walls of the second frame accommodating cavity 49, and the two third guide portions 543 are respectively guided and matched with the two third guide rails 413. In such a setting, the frame 40 can protect the structure of the push member 50 at the two ends in the axial direction O.

[0095] In the embodiment of the present application, as described above, when the sliding scroll 30 moves away from the main frame 10 along the first direction F, that is, when the flexible screen body 20 is unfolded, the first transmission member 61 drives the pushing member 50 to move closer to the sliding scroll 30. In this process, in order to improve the pushing effect of the pushing member 50, it can be considered to set the pushing member 50 as a telescopic structure, so that the pushing member 50 is extended along the first direction F during the unfolding process of the flexible screen body 20, so as to increase the contact area between the pushing member 50 and the flexible screen body 20.

[0096] Reference Figure 1 , Figure 2In a specific implementation, the push member 50 is configured to be able to extend and retract along the first direction F. The sliding mechanism 100 also includes a second transmission component 62, which is connected to the push member 50 and is in transmission connection with the first transmission component 61. The second transmission component 62 is configured to drive the push member 50 to extend along the first direction F when the first transmission component 61 drives the push member 50 to move closer to the sliding reel 30. When the first transmission component 61 drives the push member 50 to move closer to the sliding reel 30, that is, when the flexible screen body 20 is unfolded, the second transmission component 62 drives the push member 50 to extend along the first direction F. The push member 50 also extends synchronously while pushing, which can increase the contact area between the push member 50 and the flexible screen body 20 and improve the pushing effect.

[0097] Furthermore, the second transmission assembly 62 is also configured to drive the pushing member 50 to retract along the first direction F when the first transmission member 61 drives the pushing member 50 to move away from the sliding reel 30. When the first transmission member 61 drives the pushing member 50 to move away from the sliding reel 30, that is, when the flexible screen 20 is rolled up, the second transmission assembly 62 drives the pushing member 50 to retract along the first direction F. The pushing member 50 retracts synchronously while moving away from the flexible screen 20, which can reduce the contact area between the pushing member 50 and the flexible screen 20 and minimize possible interference with the flexible screen 20.

[0098] For the specific structure of the second transmission assembly 62, continue to refer to Figure 1 Exemplarily, the second transmission assembly 62 may include a second transmission member 621 and a gear 622. The second transmission member 621 is slidably connected to the pushing member 50 along the first direction F. The gear 622 is disposed on the pushing member 50 and meshes with both the first transmission member 61 and the second transmission member 621. The gear 622 is configured to drive the second transmission member 621 to slide along the first direction F when the first transmission member 61 drives the pushing member 50 to move closer to the sliding reel 30, so as to drive the pushing member 50 to extend along the first direction F. Since the gear 622 meshes with the first transmission member 61 and the second transmission member 621 at the same time, the movement of the first transmission member 61 can be transmitted to the second transmission member 621 through the gear 622, so that the linkage between the first transmission member 61 and the second transmission member 621 can be achieved.

[0099] Furthermore, the gear 622 is also configured to drive the second transmission member 621 to slide along the first direction F to drive the pushing member 50 to contract along the first direction F when the first transmission member 61 drives the pushing member 50 to move away from the sliding reel 30 .

[0100] When the flexible screen 20 is rolled up and unfolded, the sliding scroll 30 moves along the first direction F. Figure 1When the left side moves as shown in the figure, the flexible screen body 20 unfolds, driving the sliding scroll 30 to rotate in the counterclockwise direction, and the first gear shaft section 31 drives the first transmission member 61 to rotate along the second direction H. Figure 1 The push member 50 moves downward along the second direction H driven by the first transmission member 61. Figure 1 The second transmission member 621 moves downward from the drawing, and since the second transmission member 621 and the first transmission member 61 are linked by gear meshing, the second transmission member 621 moves in the first direction F. Figure 1 The push member 50 moves to the right side of the drawing, driving the push member 50 to extend along the first direction F. In other words, the push member 50 extends along the second direction H. Figure 1 The push member 50 moves downward in the figure and drives the push member 50 to extend in the first direction F, pushing the side of the flexible screen 20 away from the sliding scroll 30 to prevent the flexible screen 20 from partially bulging or warping. Figure 1 When the right side moves as shown in the figure, the flexible screen body 20 is rolled up, driving the sliding scroll shaft 30 to rotate in the clockwise direction, and the first gear shaft section 31 drives the first transmission member 61 to move along the second direction H. Figure 1 The push member 50 moves upward in the figure, and driven by the first transmission member 61, the push member 50 also moves along the second direction H toward Figure 1 The second transmission member 621 moves upward in the drawing, and since the second transmission member 621 and the first transmission member 61 are linked by gear meshing, the second transmission member 621 moves along the first direction F. Figure 1 The push member 50 moves to the left side of the drawing, driving the push member 50 to contract along the first direction F. In other words, at this time, the push member 50 moves along the second direction H. Figure 1 The push member 50 moves above the drawing and drives the push member 50 to shrink along the first direction F, away from the side of the flexible screen body 20 that faces away from the sliding scroll 30, thereby reducing the friction between the push member 50 and the flexible screen body 20, making the flexible screen body 20 smoother during the winding process, and also reducing the space occupied by the push member, making the structure more compact.

[0101] Furthermore, in the sliding and rolling mechanism 100 of the embodiment of the present application, during the sliding and rolling process of the flexible screen body 20, the pushing member 50 is synchronously controlled to move up and down and retract, thereby pushing or moving away from the flexible screen body 20, thereby achieving the effect of improving the flatness of the flexible screen body 20 and enhancing the visual perception of the flexible screen body 20 when in use.

[0102] In a specific implementation, the second transmission member 621 can be configured as a rack and can move along its own length direction when the gear 622 rotates.

[0103] In the embodiment of the present application, as mentioned above, there are two first transmission members 61. In order to avoid interference with the second transmission member 621, the two first transmission members 61 are respectively located on both sides of the second transmission member 621 in the axial direction of the gear 622 to mesh with different positions in the axial direction of the gear 622. In addition, the gear 622 can be a gear shaft structure and penetrate the push member 50 along the axial direction O.

[0104] Combine the following Figure 1 , Figure 2 The specific structure of the pushing member 50 is described. The pushing member 50 includes at least two telescopic arms 53 connected in sequence, and the adjacent telescopic arms 53 are configured to be able to slide relative to each other along the first direction F, so that the pushing member 50 can be extended and retracted along the first direction F; among the telescopic arms 53, the telescopic arms 53 located at the two ends of the first direction F are respectively connected to the frame 40 and the second transmission member 621. Since the telescopic arms 53 located at the two ends of the first direction F are respectively connected to the frame 40 and the second transmission member 621, when the second transmission member 621 slides and moves away from the frame 40 along the first direction F, the telescopic arms 53 connected to the second transmission member 621 slide and move away from the telescopic arms 53 connected to the frame 40, and the telescopic arms 53 between the telescopic arms 53 located at the two ends of the first direction F slide relative to each other, so that the pushing member 50 is extended. When the second transmission member 621 slides and approaches relative to the frame 40 along the first direction F, the telescopic arm 53 connected to the second transmission member 621 slides and approaches relative to the telescopic arm 53 connected to the frame 40, and the telescopic arms 53 between the telescopic arms 53 at both ends of the first direction F slide relative to each other, so that the pushing member 50 contracts. The fixed connection between the second transmission member 621 and the telescopic arm 53 can be achieved by welding or by fastener thread connection.

[0105] In the embodiment of the present application, for the convenience of description, the side of the push member 50 close to the frame 40 is defined as the upstream side, and the side away from the frame 40 is defined as the downstream side. In addition, the number of telescopic arms 53 is three for description, and the case where the number of telescopic arms 53 is other is similar, and no further description is given here. For example, the length dimension of the push member 50 along the first direction F can be 5-10 mm in the contracted state, and can be 15-20 mm in the extended state.

[0106] Figure 7 This is a schematic cross-sectional view of a push member in a sliding mechanism according to an embodiment of the present application. Figure 8 This is a cross-sectional schematic diagram of another structure of a push member in a sliding and rolling mechanism provided in an embodiment of the present application. Fig. 9 A cross-sectional schematic diagram of another structure of a push member in a sliding and rolling mechanism provided in an embodiment of the present application.

[0107] Reference Figure 1 , Figure 7 Each telescopic arm 53 has a receiving cavity 532 therein, and the receiving cavities 532 of each telescopic arm 53 are connected. In two adjacent telescopic arms 53, at least part of the downstream telescopic arm 53 can be inserted into the receiving cavity 532 of the upstream telescopic arm 53. In this way, the length of the pushing member 50 in the first direction F in the contracted state can be reduced.

[0108] As mentioned above, the second transmission member 621 is slidably connected to the push member 50 along the first direction F. When it is implemented specifically, reference can be made to Figure 1 A support frame 623 is provided on the inner wall of the accommodating cavity 532 of the telescopic arm 53 connected to the frame 40, and the second transmission member 621 is slidably provided on the support frame 623 along the first direction F and penetrates the accommodating cavity 532 of each telescopic arm 53. Here, since each telescopic arm 53 is provided with an accommodating cavity 532 that is interconnected, a space is provided for the second transmission member 621 to move left and right.

[0109] In addition, in order to facilitate the relative sliding of the telescopic arms 53, it is possible to consider providing guides for the telescopic arms 53. Figure 7 , Figure 8 For example, in every two adjacent telescopic arms 53, the two end portions of the telescopic arm 53 located on the downstream side along the axial direction O are protruded with fourth guide portions 534, and the cavity wall of the accommodating cavity 532 of the telescopic arm 53 on the upstream side has two fourth guide rails 5341 recessed corresponding to the two fourth guide portions 534. The two fourth guide portions 534 and the two fourth guide rails 5341 are matched one by one, so that the guides of the two adjacent telescopic arms 53 are matched.

[0110] Figure 7 In the structure shown, the surface of each telescopic arm 53 facing the flexible screen body 20 is at a different distance from the flexible screen body 20. In order to make the surface of the push member 50 facing the flexible screen body 20 form a plane, it can be referred to Figure 8 As shown, among the two adjacent telescopic arms 53, the surface of the telescopic arm 53 located on the upstream side facing the flexible screen body 20 is provided with an avoidance gap 531, and the avoidance gap 531 is configured to accommodate the telescopic arm 53 located on the downstream side, and the surfaces of each telescopic arm 53 facing the flexible screen body 20 are arranged flush with each other.

[0111] In addition, in order to further improve the stability of the guiding cooperation between the telescopic arms 53, the surface of the telescopic arm 53 on the downstream side of each adjacent telescopic arm 53, which is away from the flexible screen body 20, can be convexly provided with a fifth guide portion 535, while the wall of the accommodating cavity 532 of the telescopic arm 53 on the upstream side can be recessed with a fifth guide rail 5351 corresponding to the fifth guide portion 535, and the fifth guide portion 535 and the fifth guide rail 5351 cooperate with each other.

[0112] Of course, the surface of each telescopic arm 53 facing the flexible screen 20 is provided with a buffer pad 533 to ensure that the push member 50 does not damage the flexible screen 20. The material of the buffer pad 533 can be a polymer material, such as rubber, etc. As described above, the polymer buffer pad 533 is added to the bottom side of each telescopic arm 53, so that the push member 50 has a certain buffering effect when it contacts the flexible screen 20, and also protects the flexible screen 20 during the pushing process.

[0113] Reference Fig. 9 As another possible implementation, among all the telescopic arms 53, the telescopic arm 53 located at the upstream side is defined as the first telescopic arm 51, and the telescopic arms 53 other than the first telescopic arm 51 are defined as the second telescopic arm 52. The second telescopic arm 52 includes: a main body 521 and an insertion portion 522.

[0114] The insertion portion 522 is connected to the upstream side of the main body 521 and is configured to slide with the cavity wall of the accommodating cavity 532 of the upstream telescopic arm 53. The width dimension of the main body 521 of each second telescopic arm 52 along the axial direction O of the sliding scroll 30 is the same as the width dimension of the first telescopic arm 51 along the axial direction O of the sliding scroll 30. In this way, each second telescopic arm 52 can have the same width dimension in the axial direction O, so that the pushing force of each part of the pushing member 50 on the flexible screen 20 is more uniform.

[0115] The embodiment of the present application also provides a scrolling display device, which includes the scrolling mechanism 100 in any of the above embodiments. The scrolling display device can be, for example, a display, a television, a digital camera, a mobile phone, a tablet computer, a navigator, or any other product or component with a display function.

[0116] The sliding and rolling mechanism 100 in this embodiment has been described in detail in the above embodiments, and can bring the same or similar technical effects, which will not be described in detail here.

[0117] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0118] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
