[0002] As display devices have become indispensable tools in people's daily lives, such as mobile phones and tablets, people now have higher demands for their appearance, convenience, and multifunctionality. Traditional candybar and rectangular designs can no longer meet these needs; foldable screens often come at the cost of increased device size and weight, resulting in a monotonous appearance and devices that are thicker, heavier, and too large to hold. Therefore, further improvements are needed. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this application is to provide a simple, stable and reliable multi-directional flexible screen roll-up structure and display device.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A multi-directional flexible screen roll-up structure includes: a roll-up component comprising at least two sets of scrolls arranged in different directions, each set of scrolls having a flexible screen wound around it; a drive component comprising at least two annular tracks, with multiple annular tracks intersecting each other, the number of annular tracks being the same as the number of scrolls and corresponding one-to-one, wherein the annular tracks include a first annular track and a second annular track, the first annular track moving on the second annular track causing the scroll corresponding to the first annular track to rotate; the second annular track moving on the first annular track causing the scroll corresponding to the second annular track to rotate. This design allows for the extension and retraction of multiple screens using a single drive component, its structural design is simple, and it facilitates multi-screen interaction; furthermore, during rotation, the two annular tracks use another annular track as their running trajectory, with the two annular tracks mutually supporting each other, effectively reducing the kinetic energy of the transmission.

[0006] In a preferred embodiment, a cross hole is formed at the intersection of the first and second annular tracks. The drive assembly further includes a push rod and a star-track ball, with the star-track ball located inside the space enclosed by the multiple annular tracks. One end of the push rod is connected to the star-track ball, and the other end passes through the cross hole. The star-track ball is connected to a power source via at least two sets of transmission units arranged in different directions to control the movement of the annular tracks. This design allows the multi-directional rotation of the star-track ball to drive the push rod to rotate synchronously, and the rotation of the push rod to drive the annular tracks to rotate synchronously.

[0007] In a preferred embodiment, the transmission unit includes a transmission mechanism, which includes a driving wheel and a driven wheel that are meshed with each other.

[0008] Alternatively, the transmission unit includes a transmission mechanism, the transmission mechanism includes a locking component, the locking component is disposed at the output end of the power source, and the star orbit ball is provided with a slot that cooperates with the locking component;

[0009] Preferably, the transmission mechanism has two sets, and the two sets of transmission mechanisms are symmetrically arranged on both sides of the star orbit sphere. This design allows for force transmission through the transmission unit, enabling multi-directional rotation of the star orbit sphere, resulting in a simple structure and energy saving.

[0012] In a preferred embodiment, the annular track further includes a third annular track, which intersects with either the first annular track or the second annular track, and the third annular track moves on the intersecting annular tracks to rotate the spool corresponding to the third annular track.

[0013] Alternatively, the annular track may further include a third annular track and a fourth annular track, which are intersecting each other. The third annular track moves on the fourth annular track, causing the scroll corresponding to it to rotate; the fourth annular track moves on the third annular track, causing the scroll corresponding to it to rotate. This design enables the display of flexible screens in multiple different directions, effectively increasing the display area.

[0014] In a preferred embodiment, the interior of the reel is configured as a cavity, within which the battery and main unit structural components are housed. This design effectively saves space.

[0015] A display device includes a body, within which a multi-directional flexible screen roll-up structure as described in any one of claims 1-7 is disposed.

[0018] Beneficial effects

[0019] The present application proposes a multi-directional flexible screen roll-up structure, which uses intersecting annular tracks in different directions to connect to a scroll, on which a flexible screen can be wound. The rotation of the annular tracks can drive the scroll to rotate, thereby realizing the roll-up and unfolding of the flexible screen in multiple directions.

[0020] A push rod is installed at the intersection of the circular tracks. One end of the push rod is connected to a star track ball that can rotate in multiple directions. By rotating the star track ball, different circular tracks are driven to rotate, which can realize the expansion and contraction of different screens. Through a small transmission device, multiple flexible screens can be extended and retracted, which is easy to operate.

[0021] A display device is provided with a multi-directional flexible screen roll-up structure inside. By embedding the flexible screen inside the device, space is effectively saved and the overall size of the device is reduced. At the same time, the power consumption caused by accidental touch of the screen is reduced, and the flexible display screen can be well protected to avoid scratches, drops and other damage, which greatly extends the service life of the screen.

[0041] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0042] like Figure 1 As shown, this application discloses a multi-directional flexible screen roll-up structure, which includes a roll-up component and a drive component for driving the roll-up component. The roll-up component includes at least two sets of rollers 3 arranged in different directions. A flexible screen 4 can be wound around each roller 3. The rotation of the roller 3 drives the flexible screen 4 to roll up or unfold. The rollers 3 are arranged in different directions, meaning that the flexible screen 4 can be displayed in different directions when unfolded, making it suitable for different applications and effectively improving the flexibility of use.

[0043] like Figure 1 As shown, in one embodiment, one end of the flexible screen 4 is connected to the scroll 3 via a hinge (not shown), and the other end is wound around the scroll 3, so that the flexible screen 4 can be rolled up or unfolded when the scroll 3 rotates. In another embodiment, the flexible screen can be rolled up and unfolded by telescopic rods (not shown) between the flexible screen and the scroll. That is, the telescopic rods can be set on both sides of the flexible screen. When the flexible screen is rolled up, the telescopic rods retract; when the flexible screen is unfolded, the telescopic rods extend synchronously and play a certain supporting role to prevent deformation during the unfolding process due to the softness of the flexible screen material.

[0044] like Figure 2-4 As shown, the drive assembly includes at least two annular tracks, and multiple annular tracks are arranged in a cross pattern. The number of annular tracks is the same as the number of scrolls, and they correspond one-to-one. The annular tracks include a first annular track 21 and a second annular track 22. The first annular track 21 moves on the second annular track 22, causing the scroll 3 corresponding to the first annular track 21 to rotate. The second annular track 22 moves on the first annular track 21, causing the scroll 3 corresponding to the second annular track 22 to rotate.

[0045] like Figure 2-6 As shown, a cross hole (not shown) is formed at the intersection of the first annular track 21 and the second annular track 22. The drive assembly also includes a push rod 23 and a star-track ball 25. The star-track ball 25 is located inside the area enclosed by multiple annular tracks. One end of the push rod 23 is connected to the star-track ball 25, and the other end passes through the cross hole. The star-track ball 25 is connected to the power source 28 through at least two sets of transmission units 251 arranged in different directions to control the movement of the annular tracks. The power source 28 outputs power and transmits the power to the star-track ball through the transmission units 251. The star-track ball 25 rotates in one direction according to the power, and the push rod 23 moves synchronously, pushing the annular track to rotate.

[0046] like Figure 4 As shown, in one embodiment, a limiting block 24 is provided at the end of the push rod 23 away from the star orbit ball 25. The lower end face of the limiting block 24 is larger than the area of ​​the cross hole, so that the limiting block 24 is locked on the side of the annular track away from the star orbit ball 25, so that the push rod 23 always passes through the cross hole and can push the annular track to move.

[0047] In other embodiments, the push rod 23 may be a telescopic push rod, and the telescopic length of the push rod 23 may be adjusted according to different rotation requirements to control the push rod 23 to push different rotation tracks.

[0048] like Figure 4 and 6 As shown, in one embodiment, the transmission unit 251 includes a transmission mechanism, which includes a driving wheel 261 and a driven wheel 262 meshing with each other. The driven wheel 262 is mounted on the star orbit sphere 25, and the driving wheel 261 is connected to the output end of the power source 28 via a transmission shaft 263. The power source 28 outputs power to drive the driving wheel 261 to rotate, and the driven wheel 262 meshing with the driving wheel 261 rotates synchronously, thereby realizing the rotation of the star orbit sphere 25. Preferably, in this embodiment, the power source 28 can be a rotary motor.

[0049] like Figure 4 and 7 As shown, in another embodiment, the transmission unit 251 includes a transmission mechanism, which includes a locking member 271 disposed at the output end of the power source 28. The star track ball 25 has a circumferentially arranged slot 272 that cooperates with the locking member 271. The locking member 271 extends and engages with the slot 272 of the star track ball 25 under the action of the power source 28, thereby driving the star track ball 25 to rotate synchronously. In this embodiment, the power source 28 can be a telescopic stepper motor. Preferably, at least two sets of transmission components are provided, and the two sets of transmission components are symmetrically arranged on both sides of the star track ball 25.

[0050] like Figure 2-3 As shown, a first connecting arm 51 is provided at both radial ends of the first annular track 21, and a second connecting arm 52 is provided at both radial ends of the second annular track 22. The spool 3 includes a first spool 31 and a second spool 32. The first connecting arms 51 are connected to both ends of the first spool 31, and the second connecting arms 52 are connected to both ends of the second spool 32. The spool 3 and the connecting arms can be connected by a power transmission component 53 to realize the rotation of the spool. The power transmission component 53 can be a structure such as a gear, rack, or conveyor belt.

[0051] As shown in 1-7, in one specific embodiment, the implementation is as follows: A first transmission unit (not shown) and a second transmission unit (not shown) are arranged circumferentially in different directions on the star orbit sphere 25. The first transmission unit and the second transmission unit are respectively connected to the drive source 28. The drive source 28 outputs power, which is transmitted to the star orbit sphere 25 through the first transmission unit, causing the star orbit sphere 25 to rotate clockwise along the direction of the second annular track 22. The push rod 23 pushes the first annular track 21 to move on the second annular track 22. The first connecting arms 51 at both ends of the first annular track 21 rotate synchronously. The first connecting arms 51 transmit force to the first scroll 31 through the first power transmission component 61. The first scroll 31 rotates clockwise, thereby enabling the first flexible screen 41 to unfold from the first scroll 31.

[0052] As shown in 1-7, after the first flexible screen 41 is unfolded, the power source 28 outputs power, which is transmitted to the star orbit ball 25 through the second transmission unit, causing the star orbit ball 25 to rotate clockwise along the direction of the first annular track 21. The push rod 23 pushes the second annular track 22 to move on the first annular track 21. The second connecting arms 52 at both ends of the second annular track 22 rotate synchronously. The second connecting arms 52 transmit the force to the second scroll 32 through the second power transmission component 62. The second scroll 32 rotates clockwise, thus enabling the second flexible screen 42 to unfold from the second scroll 32.

[0053] As shown in 1-7, similarly, the power source 28 outputs power to the star orbit sphere 25 through the first transmission unit, causing the star orbit sphere 25 to rotate counterclockwise along the direction of the first annular track 21, thereby enabling the first flexible screen 41 to be wound onto the first scroll 31; the power source 28 outputs power to the star orbit sphere 25 through the second transmission unit, causing the star orbit sphere 25 to rotate counterclockwise along the direction of the second annular track 22, thereby enabling the second flexible screen 42 to be wound onto the second scroll 32.

[0054] like Figure 5 As shown, in one embodiment, the annular track further includes a third annular track 71, which is intersected with either the first annular track 21 or the second annular track 22. The third annular track 71 moves on the intersecting annular tracks, causing the scroll corresponding to the third annular track 71 to rotate.

[0055] like Figure 5As shown, one specific implementation is as follows: the third annular track 71 is placed inside the second annular track 22, the second annular track 22 is placed inside the first annular track 21, and the push rod 23 passes through the cross hole formed by the upper half of the three annular tracks. The push rod 23 is a telescopic rod. When the push rod 23 completely passes through the cross hole, that is, passes through the third annular track 71, the second annular track 22 and the first annular track 21 in sequence, the push rod 23 can move along any one of the annular tracks. The push rod 23 pushes the other two annular pipes to move synchronously on the annular track, and the corresponding scrolls of the two annular tracks rotate synchronously, which can realize the simultaneous unfolding of multiple screens; when the push rod 23 does not completely pass through the cross hole, that is, passes through the third annular track 71 and the second annular track 22 in sequence, the push rod 23 pushes the third annular track 71 to move on the second annular track 22, causing the scroll corresponding to the third annular track 71 to rotate, or the push rod 23 pushes the second annular track 22 to move on the third annular track 71, causing the scroll corresponding to the second annular track 22 to rotate, which can realize the unfolding of a single screen.

[0056] In other embodiments (not shown), the annular track further includes a third annular track and a fourth annular track, which are intersected. The third annular track moves on the fourth annular track, causing the scroll corresponding to the third annular track to rotate; the fourth annular track moves on the third annular track, causing the scroll corresponding to the fourth annular track to rotate. Multiple push rods are provided at the intersection holes of the third and fourth annular tracks, and these push rods are configured as telescopic push rods, capable of extending and retracting according to different rotation requirements to control the rotation of different annular tracks.

[0057] In this embodiment, the third and fourth annular tracks have different diameters from the first and second annular tracks, creating a spatial misalignment between the two sets of annular tracks so that they do not interfere with each other during their rotation.

[0058] Preferably, the third and fourth annular tracks can use the same star track ball as the first and second annular tracks. The star track ball is equipped with several retractable push rods on its circumference, which can be inserted into the cross holes of the third and fourth tracks and the cross holes of the first and second tracks, respectively, to realize the distribution, unfolding and rolling of different flexible screens, which can effectively save internal space.

[0059] Alternatively, another star-orbit sphere can be set up inside the area enclosed by the intersection of the third and fourth annular tracks, allowing for independent control of the rotation of the third and fourth annular tracks, thus enabling the synchronous deployment of different groups of flexible screens.

[0060] As one of the preferred embodiments ( Figure 8As shown, the first annular track 21 and the second annular track 22 are perpendicular to each other, that is, the first scroll 31 is set along the X-axis direction and the second scroll 32 is set along the Z-axis direction. The two are arranged in a cross structure and there is a spatial misalignment in the vertical direction. The drive component is set between the first scroll 31 and the second scroll 32.

[0061] like Figure 8 As shown, the two axial ends of the first spool 31 are connected to the first annular track 21 via the first connecting arm 51, and the two axial ends of the second spool 32 are connected to the second annular track 22 via the second connecting arm 52. The output ends of the first power source (not shown) and the second power source (not shown) of the drive assembly are respectively connected to the star orbit sphere 25 via the transmission unit.

[0062] like Figure 8 As shown, the interiors of the first scroll 31 and the second scroll 32 are set as cavities, and the main components of the device, such as the host and battery, are arranged inside the cavities, which effectively saves internal space of the device and enhances its practicality.

[0063] like Figure 9 As shown, a display device includes a body 11, the interior of which is configured as a cavity, and the aforementioned multidirectional flexible screen roll-up structure is disposed within the cavity.

[0064] like Figure 9-10 As shown, the side of the body 11, in conjunction with the multi-directional flexible screen roll-up structure, has several outlets 12, allowing the flexible screen and the outlets 12 to be unfolded as needed. When the flexible screen extends outward, screens in two or more directions can appear. With multiple screens, a single person can perform multiple tasks simultaneously, or work in split-screen mode; multiple people can also use it; or individual screens can be used for separate displays as needed. This achieves portability for multi-screen work, while also sharing the workload among multiple screens, greatly improving screen lifespan. By configuring multiple screens, the functionality of the device (e.g., a mobile phone) in standby mode can be increased, effectively reducing power consumption.

[0065] like Figure 9-10 As shown, the upper surface of the body 11 is provided with a main screen 13. When the large screen is not needed, users can view, receive, and reply to messages on the main screen 13 in a timely manner, quickly understand information, play music in real time, and perform other portable operations, reducing the burden on the lifespan of the flexible screen caused by the extension and curling of a small amount of work.

[0066] like Figure 9-10As shown, preferably, the upper surface of the main body 11 is also equipped with several small auxiliary screens 14 and (DIY) display windows 15, all of which use LCD or OLED displays and can function as electronic clocks, weather displays, and other customized functions. The small auxiliary screens 14 allow users to use them directly when handling tasks that do not require a large flexible display, reducing power consumption and providing convenience. This indirectly reduces the number of times the flexible screen needs to be folded, protecting the flexible display and extending its lifespan. The display windows 15 are designed to be artistic and cute, allowing users to upload DIY drawings as decorations for the device, making the use of the device easy and enjoyable.

[0067] like Figure 9-10 As shown, preferably, the side wall of the device is also provided with several buttons 16, which can be used to adjust the volume of the device and control the pulling and rolling of the flexible screen.

[0068] It should be noted that the technical features of the above embodiments, such as "first scroll", "first flexible screen", "first circular track", "first connecting arm", "second scroll", "second flexible screen", "second circular track", "second connecting arm", "main screen", "auxiliary screen", etc., can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0069] This disclosure is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
