[0035] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] This embodiment provides a roll-up screen assembly, which can be used on a display device, such as a mobile phone, a television, or a tablet computer. Compared with the existing rigid screen, the roll-up screen assembly provided in this embodiment can be unfolded or retracted according to demand, which improves the fun of the electronic device and facilitates the miniaturization of the electronic device and improves the portability of the electronic device.

[0039] like Figure 1 to Figure 2 As shown, the roll-up screen assembly includes a housing 100, a storage assembly 200, a flexible screen 300 and a support assembly 400. The housing 100 is a mounting component and a protective component of the entire roll-up screen assembly. The housing 100 has a storage space 101. The storage assembly 200 is placed in the storage space 101. The flexible screen 300 in a non-expanded state and the support assembly 400 in a non-expanded state are placed in the storage space 101 as a whole. The flexible screen 300 in an expanded state and a partial structure of the support assembly 400 in an expanded state are placed in the storage space 101, and the remaining part is placed outside the storage space 101. An entrance 102 is formed on the housing 100, and the entrance 102 is connected to the storage space 101. The flexible screen 300 and a partial structure of the support assembly 400 enter and exit the storage space 101 through the entrance 102.

[0040] In some specific embodiments, the housing 100 is in a cubic shape, and the entrance 102 is a through hole that horizontally penetrates the side plate of the housing 100. It should be noted that the side plate here can be a front side plate, a rear side plate, a left side plate or a right side plate, and the entrance 102 can be set as a long hole according to needs, such as a waist-shaped hole, a rectangular hole, etc. Of course, in other embodiments, the entrance 102 can also be a through hole that vertically penetrates the top plate or the bottom plate of the housing 100. As long as the entrance 102 can allow the flexible screen 300 and the support assembly 400 to enter and exit the accommodating space 101, it is within the scope of the technical solution of the present invention.

[0041] The storage assembly 200 is used to recycle the flexible screen 300 or release the flexible screen 300. The flexible screen 300 is a screen that can be deformed. Its specific structure is a prior art and will not be described in detail here. Figure 1 and Figure 2As shown, the flexible screen 300 has a first end and a second end that are relatively arranged in a first direction, the first end of the flexible screen 300 is placed at the entrance and exit 102, and the second end of the flexible screen 300 is fixedly connected to the storage component 200. Under the drive of external force, the flexible screen 300 can be gradually stored in the storage component 200. In the process of the flexible screen 300 being gradually stored in the storage component 200, the first end of the flexible screen 300 can move along the first direction toward the direction close to the storage component 200.

[0042] In some embodiments, the first direction is a horizontal direction, and the flexible screen 300 can be unfolded along the horizontal direction; in some embodiments, the first direction is a vertical direction, and the flexible screen 300 can be unfolded along the vertical direction; in some embodiments, the first direction is an inclined direction at an angle to the horizontal direction, and the flexible screen 300 can be unfolded along the inclined direction.

[0043] In some specific embodiments, the storage assembly 200 includes a storage roller and a drive motor, the drive motor is used to drive the storage roller to rotate around its own central axis, and the second end of the flexible screen 300 is fixed to the cylindrical surface of the storage roller. Figure 1 When the flexible screen 300 rotates counterclockwise as shown in FIG, the flexible screen 300 is gradually wound around the cylindrical surface of the receiving roller. Figure 1 When rotating in the clockwise direction as shown in , the receiving roller gradually releases the flexible screen 300 .

[0044] Of course, in other embodiments, the storage component 200 is not limited to the storage roller and the drive motor. As long as the flexible screen 300 can have a retracted state in which it is gradually stored on the storage component 200 and an expanded state in which it is gradually expanded along the first direction, it can be used as the storage component 200 of the present application.

[0045] Continue to refer to Figure 1 and Figure 2 As shown, the support assembly 400 also has a retracted state and an extended state, and the states of the support assembly 400 and the flexible screen 300 are synchronized, that is, when the flexible screen 300 is gradually extended, the support assembly 400 is synchronously extended; when the flexible screen 300 is gradually retracted, the support assembly 400 is synchronously retracted. The support assembly 400 can support the part of the structure of the flexible screen 300 that has been extended and moved to the outside of the housing 100, so as to improve the extension stability and extension accuracy of the flexible screen 300, reduce the probability of damage to the flexible screen 300, and avoid the flexible screen 300 from being unable to be accurately retracted due to poor extension accuracy.

[0046] Specifically, continue to refer to Figure 1 and Figure 2As shown, the support assembly 400 includes a plurality of support plates 401 and at least one first connecting member 402, wherein a first connecting member 402 is connected between each two adjacent support plates 401, one end of the first connecting member 402 is slidably connected to one of the two adjacent support plates 401, and the other end of the first connecting member 402 is rotatably connected to the other of the two adjacent support plates 401. The free end of the support plate 401 located at the end of the entire support assembly 400 is fixedly connected to the first end of the flexible screen 300.

[0047] Since two adjacent support plates 401 are connected by the first connecting member 402, and the connection method is a combination of rotation and sliding, the positional relationship between the two support plates 401 can be flexibly adjusted and changed, that is, the plurality of support plates 401 included in the support assembly 400 can be as follows: Figure 1 The vertical setting shown can also be Figure 2 The horizontal settings shown are located in the same horizontal plane.

[0048] It should be noted here that when the entire roll-up screen assembly is in the initial state (i.e., the flexible screen 300 is not pulled by an external force from outside the housing 100), the support plate 401 located at the outermost end of the support assembly 400 and fixedly connected to the flexible screen 300 is placed at the entrance 102 along the first direction, so that the user can apply force to the support plate 401 at the same time when pulling the flexible screen 300, thereby synchronously pulling the flexible screen 300 and the support plate 401 to the outside of the housing 100. When the entire roll-up screen assembly is in the initial state, the support plates 401 in the support assembly 400 except the support plate 401 located in the entrance 102 are vertically arranged in the accommodating space 101, thereby reducing the space occupied by the support assembly 400.

[0049] When the entire roll-up screen assembly is gradually unfolded (i.e., the flexible screen 300 is pulled by an external force from outside the housing 100), the support plate 401 located at the entrance 102 is simultaneously pulled by an external force, and the pulling force is transmitted through the first connecting member 402, and the remaining support plates 401 are successively flattened and successively moved to the outside of the housing 100 through the entrance 102. As the flexible screen 300 is gradually unfolded, the number of support plates 401 used to support the flexible screen 300 gradually increases, so the support assembly 400 has a large supporting rigidity for the flexible screen 300, a good supporting effect, and can smoothly unfold the flexible screen 300.

[0050] In some specific embodiments, the first connecting member 402 is a rectangular plate, and a slideway 406 is provided on one end of the first connecting member 402, and the slideway 406 is substantially extended along the first direction. A sliding column 405 is provided on the support plate 401 on one side of the first connecting member 402, and the sliding column 405 is slidably connected in the slideway 406, thereby realizing the sliding connection between the first connecting member 402 and one of the support plates 401. Optionally, the sliding column 405 is a cylinder vertically protruding on the surface of the support plate 401. In some specific embodiments, a first shaft hole is provided on the other end of the first connecting member 402, and a first rotating column 404 is provided on the support plate 401, and the first rotating column 404 is rotatably connected in the first shaft hole, thereby realizing the rotational connection between the other end of the first connecting member 402 and the other support plate 401. Optionally, the first rotating column 404 is a cylinder protruding on the surface of the support plate 401, and the first rotating shaft hole is a circular hole.

[0051] In the process of two adjacent support plates 401 being expanded from a parallel state in which both are vertically arranged to a coplanar state in the same horizontal plane, one of the support plates 401 can rotate 90° around the first rotating column 404, and the other support plate 401 can rotate 90° around the sliding column 405, and the support plate 401 can synchronously move along the first direction during the rotation around the sliding column 405, so that the sliding column 405 slides from one end of the slide 406 to the other end of the slide 406, thereby avoiding interference between the two support plates 401 during the rotation process.

[0052] It should be noted that, since both support plates 401 need to rotate, in order to avoid interference with the first connecting member 402 during the rotation of the support plate 401, in some embodiments, the first connecting member 402 can be set on the outside of the two adjacent support plates 401. For example, when the two adjacent support plates 401 are arranged left and right, the first connecting member 402 can be located as a whole on the front side or the rear side of the two support plates 401. Adaptively, the sliding column 405 and the first rotating column 404 also need to be set on the front side or the rear side of the support plate 401. At this time, it is necessary to additionally set a limiting angle to limit the rotation angle of the two support plates 401; of course, in some other embodiments, the first connecting member 402 can also be set between the two adjacent support plates 401. At this time, it is necessary to set a limiting groove at the position where the first rotating column 404 or the sliding column 405 is set on the support plate 401 to avoid the end of the support plate 401 while limiting the rotation angle of the support plate 401, so that the support plate 401 can be smoothly rotated to the target position.

[0053] In order to ensure that the multiple support plates 401 of the support assembly 400 can be stably located in the same horizontal plane and to prevent the support plates 401 from excessively rotating, in some more specific embodiments, for example Figure 4 and Figure 5As shown, the slide 406 includes a straight expansion section 4061 and an arc-shaped limiting section 4062 connected in an L shape. The angle between the straight expansion section 4061 and the first direction is an acute angle, for example, 5° or 10°. The arc-shaped limiting section 4062 is arranged on one side of the straight expansion section 4061 away from the other end of the first connecting member 402, and the arc-shaped limiting section 4062 is an end of the straight expansion section 4061 away from the arc-shaped limiting section 4062 (i.e. Figure 4 or Figure 5 The point a shown in FIG. 4 is the center of the circle and the length of the straight line segment 4061 (i.e. Figure 4 or Figure 5 The distance between ab shown in FIG. 4 is a circular arc groove with a radius. Setting the included angle between the straight line expansion section 4061 and the first direction to an acute angle can improve the sliding smoothness of the sliding column 405 in the slideway 406.

[0054] like Figure 4 and Figure 5 As shown, the L-shaped slideway 406 has three end points a, b, and c. When two adjacent support plates 401 are vertically arranged in the receiving space of the housing 100, as shown in FIG. Figure 4 As shown, the sliding post 405 is located at point a in the slideway 406. As the flexible screen 300 is gradually unfolded, the sliding post 405 gradually slides from point a to point b, and then from point b to point c. When the sliding post 405 is placed at point c, as shown in FIG. Figure 5 As shown, two adjacent support plates 401 are horizontally arranged and located at the same level. At this time, since the sliding column 405 and the first connecting member 402 form a limit in the vertical direction, the support plate 401 can no longer rotate, thereby improving the rigid support effect of the support assembly 400 on the flexible screen 300.

[0055] In order to further improve the smoothness of the sliding column 405 sliding in the slideway 406, as shown in FIG. Figure 7 and Figure 8 As shown, the roll-up screen assembly further includes two one-way lifting mechanisms 500, which are respectively located on the upper and lower sides of the support assembly 400. Figure 7 As shown, when the flexible screen 300 is gradually unfolded, the one-way lifting mechanism 500 located on the upper side of the support assembly 400 can press down the first connecting member 402, so that the sliding column 405 slides smoothly and quickly from the straight unfolding section 4061 to the arc-shaped limiting section 4062. Figure 8 As shown, when the flexible screen 300 is gradually retracted onto the storage assembly 200, the one-way lifting mechanism 500 located at the lower side of the support assembly 400 can lift the first connecting member 402 so that the sliding column 405 can slide smoothly and quickly from the arc-shaped limiting section 4062 to the straight expansion section 4061.

[0056] In some specific embodiments, continue to refer to Figure 7 and Figure 8 As shown, the one-way lifting mechanism 500 includes a mounting seat 501, a push rod 502 and an elastic body 504. The mounting seat 501 is provided with a mounting groove 5011 opening toward the support assembly 400, and the push rod 502 and the elastic body 504 are both located in the mounting groove 5011. The push rod 502 is extended along a second direction perpendicular to the first direction, and when the first direction is a horizontal direction, the second direction is a vertical direction. One end of the push rod 502 away from the support assembly 400 is rotatably connected to the mounting seat 501 through a rotating shaft 503, and the push rod 502 abuts against one side wall of the mounting groove 5011 in the first direction, and the push rod 502 is spaced apart from the other side wall of the mounting groove 5011 in the first direction, thereby forming an elastic body accommodating space. The elastic body 504 is arranged in the elastic body accommodating space along the first direction, and one end of the elastic body 504 is fixedly arranged, for example, it can be fixedly arranged on the other side wall of the mounting groove 5011 in the first direction, and the other end of the elastic body 504 is connected to the middle part of the top rod 502.

[0057] Since the push rod 502 is in contact with one side wall of the mounting groove 5011 (this side wall is defined as the abutting wall of the mounting groove 5011) and is spaced apart from the other side wall of the mounting groove 5011 (this side wall is defined as the non-abutting wall of the mounting groove 5011), when the push rod 502 is subjected to an external force toward the abutting wall, the push rod 502 is restricted from rotating around the rotating shaft 503, and when the push rod 502 is subjected to an external force toward the non-abutting wall, the push rod 502 is able to rotate around the rotating shaft 503.

[0058] For example, Figure 7 As shown, when the support plate 401 of the support assembly 400 is subjected to a horizontal rightward external force, the top rod 502 located on the upper side of the support assembly 400 is limited by the abutting wall of the mounting groove 5011 in which it is accommodated, and therefore can only be in a vertical state. At this time, since the lower end of the top rod 502 can abut against the upper surface of the first connecting member 402, during the horizontal rightward movement of the first connecting member 402, the top rod 502 can press down one end of the first connecting member 402 where the slideway 406 is set. Since the top rod 502 located on the lower side of the support assembly 400 is not limited by the abutting wall of the mounting groove 5011 in which it is accommodated, the top rod 502 can rotate toward the non-abutting wall of the mounting groove 5011, so the top rod 502 cannot apply force to the first connecting member 402.

[0059] Similarly, if Figure 8As shown, when the support plate 401 of the support assembly 400 is subjected to a horizontal leftward external force, the push rod 502 located at the lower side of the support assembly 400 is limited by the abutting wall of the mounting groove 5011 in which it is accommodated, and therefore can only be in a vertical state. At this time, since the upper end of the push rod 502 can abut against the lower surface of the first connecting member 402, during the horizontal leftward movement of the first connecting member 402, the push rod 502 can lift up one end of the first connecting member 402 where the slideway 406 is set. Since the push rod 502 located at the upper side of the support assembly 400 is not limited by the abutting wall of the mounting groove 5011 in which it is accommodated, the push rod 502 can rotate toward the non-abutting wall of the mounting groove 5011, so the push rod 502 cannot apply force to the first connecting member 402.

[0060] It should be noted that the push rods 502 of the two one-way lifting mechanisms 500 are arranged opposite to one end of the first connecting member 402 where the slideway 406 is arranged, and the elastic bodies 504 of the two one-way lifting mechanisms 500 are respectively located on both sides of the slideway 406, so that the two one-way lifting mechanisms 500 play a role in the unfolding process and the retracting process of the flexible screen 300. In addition, it should be noted that the push rod 502 can press the first connecting member 402 in the vertical direction, but because the volume of the push rod 502 is very small compared to the support plate 401, the existence of the push rod 502 does not affect the movement of the support plate 401 in the first direction.

[0061] In order to further improve the support stiffness and support stability of the support plate 401 of the support assembly 400 after it is unfolded, as shown in FIG. Figure 3 , Figure 4 as well as Figure 6 As shown, the roll-up screen assembly further includes a second connecting member 403, and a second connecting member 403 is connected between each two adjacent support plates 401, and the second connecting member 403 is rotatably connected to the two adjacent support plates 401. Figure 6 As shown, a second rotating column 407 is provided on one of the two adjacent support plates 401, and a third rotating column 408 is provided on the other. The second connecting member 403 is a rectangular plate, and a second rotating shaft hole and a third rotating shaft hole are respectively provided on both ends of the second connecting member 403. The second rotating column 407 is rotatably connected in the second rotating shaft hole, and the third rotating column 408 is rotatably connected in the third rotating shaft hole.

[0062] Optionally, the third rotating column 408 and the second rotating column 407 are both cylindrical, and the second rotating shaft hole and the second rotating shaft hole are both round holes. In order to limit the rotation angle, avoidance grooves are provided at the positions where the second rotating column 407 and the third rotating column 408 are provided on the two support plates 401, and the avoidance grooves are used to avoid the end of the second connecting member 403 and limit the angle value that the support plate 401 can rotate relative to the second connecting member 403. In this embodiment, the angle value is not less than 90 degrees.

[0063] By providing a second connecting member 403 and utilizing the second connecting member 403 and the first connecting member 402 to jointly connect two adjacent support plates 401, not only can the stability of the two support plates 401 in the same horizontal plane and the supporting rigidity of the flexible screen 300 be improved, but the cooperation between the two can also prevent the support plates 401 from excessive rotation.

[0064] In some specific embodiments, the length of the second connecting member 403 is less than the length of the first connecting member 402. In this way, when two adjacent support plates 401 are in the same horizontal plane, the first connecting member 402 and the second connecting member 403 form a trapezoidal structure with the portion of the two support plates 401 located between the first connecting member 402 and the second connecting member 403, thereby further ensuring that the two support plates 401 cannot continue to rotate, which is conducive to improving the support rigidity and support effect of the flexible screen 300.

[0065] This embodiment also provides a display device, which includes the above-mentioned rolling screen assembly. By using the rolling screen assembly, the flexible screen 300 of the display device can be stably supported during the unfolding process, thereby improving the unfolding accuracy and stability, making the flexible screen 300 less susceptible to damage, and facilitating the flexible screen 300 to achieve high-precision retraction, and the entire display device has good use effect and long service life.

[0066] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
