Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a flexible screen support mechanism and a rollable electronic device. Background Technology

[0002] For rollable electronic devices, the support mechanism of the flexible screen is a key component. When the flexible screen is pulled out of the roll, it needs to be supported by a non-bending support mechanism to prevent the flexible screen from deforming and affecting its display and touch. When the flexible screen is rolled into the roll, the support mechanism must not interfere with the flexible screen's rolling action.

[0003] Existing rollable electronic devices are mostly used in larger television devices. There are generally two types of support mechanisms for flexible screens: one uses a cross mechanism as the support mechanism for the flexible screen. When the flexible screen is pulled out of the roll, the cross mechanism on the back of the flexible screen unfolds and supports the flexible screen. When the flexible screen is retracted, the cross mechanism closes, and the screen rolls up and is stored. The other uses a vertical chain as the support mechanism for the screen. The rotation direction of the chain is perpendicular to the rolling direction of the screen. When the flexible screen is pulled out of the roll, the vertical chains at the top and bottom of the flexible screen are pulled out at the same time. Since the rotation direction of the chain is perpendicular to the rolling direction of the flexible screen, the chain can support the flexible screen. When the flexible screen is retracted, the flexible screen and the chain are rolled up and stored separately in different positions.

[0004] The two flexible screen support mechanisms mentioned above are large in size and complex in structure. Furthermore, the flexible screen support mechanism and the display screen are set up separately. When the flexible screen is rolled up, the flexible screen and the flexible screen support mechanism are stored in different positions, resulting in a large storage device size. Therefore, the existing solutions are not suitable for portable rolling devices. Summary of the Invention

[0005] In view of this, this application provides a flexible screen support mechanism that is simple in structure, has a small storage space, and is suitable for portable devices.

[0006] It is also necessary to provide a rollable electronic device that utilizes the flexible screen support mechanism described above.

[0007] A first aspect of this application provides a flexible screen support mechanism. The flexible screen support mechanism supports a flexible screen and includes at least two parallel support structures. Each support structure includes a support component and a rotating component that cooperates with the support component. The support components of two adjacent support structures are rotatably connected by a first rotating shaft. The rotating component and the cooperating support component are rotatably connected by a second rotating shaft, which is perpendicular to the first rotating shaft. The rotating components of two adjacent support structures are rotatably connected by a third rotating shaft, which is perpendicular to the third rotating shaft. The rotating component can be flipped relative to the support component and can switch between a first state and a second state. When the rotating component is in the first state, the axis of the first rotating shaft is collinear with the axis of the third rotating shaft, and the two adjacent support structures can rotate relative to either the first or the third rotating shaft to allow the flexible screen support mechanism to curl. When the rotating component is in the second state, the axis of the first rotating shaft intersects with the axis of the third rotating shaft, and the two adjacent support structures cannot rotate relative to each other to prevent the flexible screen support mechanism from curling. The support structure includes a rotating component that can rotate relative to the support assembly. Flipping the rotating component allows the flexible screen support structure to switch between a first state and a second state. The flexible screen support mechanism can not only support the flexible screen, but also be rolled up and stored together with the flexible screen, thus realizing the conversion between rolling and flattening of the flexible screen support mechanism. It is not only simple in structure and occupies little space, but can also be applied to large-size rollable TVs and small-size portable rollable electronic devices.

[0008] In one embodiment of this application, the axis of the first rotating shaft is perpendicular to the axis of the third rotating shaft. When the axis of the first rotating shaft is perpendicular to the axis of the third rotating shaft, the rotating component is parallel to the bottom wall of the access channel of the rollable electronic device and has a large contact area, so that the rotating component and the support component are in close contact, thereby further enhancing the stability of the flexible screen support mechanism composed of multiple support structures.

[0009] In one embodiment of this application, the support assembly includes a support plate and a connector formed on one end of the support plate. Connectors of two adjacent support structures are rotatably connected via a first rotation axis, and the rotation assembly is rotatably connected to the connector via a second rotation axis. The support plate supports the flexible screen, and the connector is used to connect to the rotation assembly. The support plate and the connector together form the support assembly, which facilitates the fixing of the flexible screen and the switching of the rotation assembly relative to the support assembly between a first state and a second state.

[0010] In one embodiment of this application, the rotating assembly includes a first rotating member and a second rotating member, with one end of the first rotating member overlapping the second rotating member. The first rotating member and the second rotating member are rotatably connected to the connecting member via a second rotating shaft. The first rotating member and the second rotating member of two adjacent support structures are rotatably connected via the third rotating shaft. The overlap of the first rotating member of the same support structure with the second rotating member increases the consistency of the rotating assembly's rotation during flipping, thereby facilitating the stable maintenance of the support assembly in the first and second states. The rotatable connection between the first rotating member and the second rotating member of two adjacent support structures facilitates the curling of the flexible screen support mechanism.

[0011] In one embodiment of this application, the first rotating member further includes a first stepped portion, and the second rotating member further includes a second stepped portion. The first stepped portion and the second stepped portion cooperate, with the first stepped portion overlapping the second stepped portion. The cooperation between the first stepped portion and the second stepped portion makes the overlap between the first rotating member and the second rotating member easier, further increasing the consistency of the rotation of the rotating assembly during rotation, thereby helping the support assembly to stably maintain itself in the first state and the second state.

[0012] In one embodiment of this application, the connector includes two receiving slots. The first rotating member includes a first connecting portion, and the second rotating member includes a second connecting portion. A second rotating shaft passes through the first connecting portion and the second connecting portion respectively and is fixed to the inner walls of the two receiving slots. The first connecting portion and the second connecting portion are rotatable relative to the second rotating shaft, so that the rotating assembly can switch between the first state and the second state. The first connecting portion and the second connecting portion are connected to the connector via a second rotating shaft, which facilitates the consistency of the rotating assembly during rotation and makes it easier to achieve the curling of the flexible screen support mechanism.

[0013] In one embodiment of this application, one end of the connector is provided with a first connecting lug, and the other end is provided with two second connecting lugs, with a first groove formed between the two second connecting lugs. The first connecting lug of one of two adjacent support structures is placed in the first groove of the other, and the first connecting lug of one structure is rotatably connected to the two second connecting lugs of the other through a first rotating shaft, thereby realizing a rotatable connection between two adjacent support components. The use of the cooperation between the first connecting lug, the second connecting lug, the first groove, and the third rotating shaft to achieve a rotatable connection between two adjacent support structures not only facilitates the bending of the flexible screen support mechanism but also allows for timely replacement of faulty support structures, further reducing maintenance costs and time.

[0014] In one embodiment of this application, the first rotating component includes two third connecting lugs, and the second rotating component includes a fourth connecting lug. A second groove is formed between the two third connecting lugs. The fourth connecting lug of one of two adjacent rotating components is placed in the second groove of the other, and the fourth connecting lug of one component is rotatably connected to the two third connecting lugs of the other through the third rotating shaft, thereby realizing the rotatable connection between the two adjacent rotating components. Utilizing the cooperation between the third connecting lugs, fourth connecting lugs, second groove, and third rotating shaft to achieve the rotatable connection between two adjacent rotating components not only facilitates the bending of the flexible screen support mechanism but also allows for timely replacement of problematic support structures, further reducing maintenance costs and time.

[0015] A second aspect of this application provides a rollable electronic device. The rollable electronic device includes a roll, a spool, a flexible screen, and a flexible screen support mechanism as described above. The roll has a receiving cavity inside, and the spool receives and is rotatably connected to the receiving cavity. The flexible screen covers a support component of the flexible screen support mechanism. One end of the flexible screen support mechanism is fixed to the spool, and the other end can be wound around the spool or pulled out of the roll. When the flexible screen is wound around the spool along with the flexible screen support mechanism, the rotating component is in a first state. When the flexible screen is pulled out of the roll along with the flexible screen support mechanism, the rotating component flips relative to the support component, and the rotating component is in a second state. The flexible screen support mechanism of the rollable electronic device can switch between rolling and flattening, not only supporting the flexible screen but also allowing it to be rolled up and stored together with the flexible screen. It has a simple structure and occupies little space.

[0016] In one embodiment of this application, the roll includes an inlet / outlet channel communicating with the receiving cavity and a first guide groove and a second guide groove disposed on one side of the inlet / outlet channel; the end of the flexible screen support mechanism away from the roll enters and exits through the inlet / outlet channel; the first guide groove has a first inclined surface, the first inclined surface faces the flexible screen, and the first inclined surface is close to the flexible screen in the direction in which the flexible screen support structure is pulled out; the second guide groove has a second inclined surface, the second inclined surface faces the side of the flexible screen support mechanism away from the flexible screen, and the second inclined surface is away from the flexible screen support structure in the direction in which the flexible screen support structure is pulled out; during the process of the flexible screen support mechanism being pulled out of the roll, the end of the rotating component in the first state away from the roll abuts against the first inclined surface, and the rotating component flips from the first state to the second state; during the process of the flexible screen support mechanism being wound on the roll, the end of the rotating component in the second state close to the roll abuts against the second inclined surface, and the rotating component flips from the second state to the first state. The guide groove enables the first and second rotating components of the flexible screen support mechanism to switch between the first and second states.

[0017] In one embodiment of this application, the reel includes a first housing and a second housing, and the inlet / outlet channel and the receiving cavity are formed by the first housing and the second housing. When the flexible screen support mechanism moves in and out of the inlet / outlet channel, the first housing is close to the flexible screen, and the second housing is close to the flexible screen support mechanism. The first inclined surface is disposed on the first housing, and the second inclined surface is disposed on the second housing. Distributing the first inclined surface and the second inclined surface on the first housing and the second housing respectively optimizes the positional rationality of the first inclined surface and the second inclined surface, thereby facilitating the transition between the first rotating member and the second rotating member of the flexible screen support mechanism in the first state and the second state.

[0018] In one embodiment of this application, when the support assembly includes a support plate and a connector formed on one end of the support plate, the flexible screen is attached to the support plate of the flexible screen support mechanism. This improves the flatness of the flexible screen and prevents deformation. Attached Figure Description

[0032]

[0033]

[0034] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0035] To further illustrate the technical means and effects adopted in achieving the intended purpose of this application, the following is in conjunction with the appendix. Figure 1-12 The following detailed description of the specific implementation methods, structures, features, and effects of the flexible screen support mechanism and rollable electronic device provided in this application, along with preferred embodiments, is provided. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0036] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have a component that is centrally located. When a component is considered to be "set" on another component, it can be directly set on the other component or may also have a component that is centrally located.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] For rollable display devices, the flexible screen support mechanism is a crucial component. When the flexible screen extends out of the roll, a non-bendable support mechanism is needed to prevent deformation that could affect the display and touch functionality. Conversely, when the flexible screen is rolled back into the roll, the support mechanism must not interfere with the rolling motion. Currently, commonly used flexible screen support mechanisms are large, complex, and separate from the display screen. When the flexible screen rolls up, it and the support mechanism are stored in different locations, resulting in a large storage device. Therefore, existing solutions are unsuitable for portable rollable devices.

[0039] Therefore, this application provides a rollable electronic device with a simple structure, small storage space, and applicability to portable devices. The rollable electronic device provided by this application includes a roll, a spool, a flexible screen, and a flexible screen support mechanism as described above. The roll has a receiving cavity inside, the spool receives and is rotatably connected to the receiving cavity, the flexible screen covers the flexible screen support mechanism, one end of the flexible screen support mechanism is fixed to the spool, and the other end can enter and exit the roll. To achieve this function of the flexible screen support mechanism entering and exiting the roll, this application designs a flexible screen support mechanism.

[0040] The flexible screen support mechanism of this application includes at least two parallel support structures. Each support structure includes a support component and a rotating component that cooperates with the support component. The support components of two adjacent support structures are rotatably connected by a first rotating shaft. The rotating component and the supporting component that cooperates with it are rotatably connected by a second rotating shaft, which is perpendicular to the first rotating shaft. The rotating components of two adjacent support structures are rotatably connected by a third rotating shaft, which is perpendicular to the third rotating shaft. The rotating component can be flipped relative to the support component and can switch between a first state and a second state. When the rotating component is in the first state, the axis of the first rotating shaft is collinear with the axis of the third rotating shaft, and the two adjacent support structures can rotate relative to the first rotating shaft or the third rotating shaft so that the flexible screen support mechanism can be rolled up. When the rotating component is in the second state, the axis of the first rotating shaft intersects with the axis of the third rotating shaft, and the two adjacent support structures cannot rotate relative to each other so that the flexible screen support mechanism cannot be rolled up. To accommodate the rotating assembly of the flexible screen support structure provided in this application, a first guide groove and a second guide groove are provided within the rollable electronic device. The first guide groove has a first inclined surface facing the flexible screen and moving closer to the flexible screen in the direction in which the flexible screen support structure is pulled out. The second guide groove has a second inclined surface facing the side of the flexible screen support mechanism away from the flexible screen and moving away from the flexible screen support mechanism in the direction in which the flexible screen support structure is pulled out. During the process of the flexible screen support mechanism being pulled out of the roll, the rotating assembly in the first state abuts against the first inclined surface, and the rotating assembly flips from the first state to the second state. During the process of the flexible screen support mechanism being wound around the roll, the rotating assembly in the second state abuts against the second inclined surface, and the rotating assembly flips from the second state to the first state. The rotating assembly and support assembly can be implemented using different structures. For ease of understanding, they are described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Please see Figure 1-5This application provides a flexible screen support mechanism 110. The flexible screen support mechanism 110 is used to support a flexible screen 120. The flexible screen support mechanism 110 includes at least two support structures 10. Each support structure 10 includes a support component 101 and a rotating component 102 that cooperates with the support component 101. The support components 101 of two adjacent support structures 10 are rotatably connected by a first rotating shaft (not shown). The rotating component 102 and the cooperating support component 101 are rotatably connected by a second rotating shaft 15, which is perpendicular to the first rotating shaft. The rotating components 102 of two adjacent support structures 10 are rotatably connected by a third rotating shaft (not shown). The second rotating shaft 15 is perpendicular to the third rotating shaft.

[0042] Specifically, the rotation axis of the two support components 101 of two adjacent support structures 10 is defined as L1, and the rotation axis of the two rotation components 102 of two adjacent support structures 10 is defined as L2.

[0043] In this embodiment, L1 is the axis of the first rotating shaft, and L2 is the axis of the third rotating shaft.

[0044] The state of the rotating component 102 when L1 and L2 are collinear is defined as the first state, and the state of the rotating component 102 when L1 and L2 intersect is defined as the second state. The rotating component 102 can flip relative to the support component 101 and switch between the first and second states. When the rotating component 102 is in the first state, the two adjacent support structures 10 can rotate relative to each other so that the flexible screen support mechanism 110 can be rolled up. When the rotating component 102 is in the second state, the two adjacent support structures 10 cannot rotate relative to each other so that the flexible screen support mechanism 110 cannot be rolled up.

[0045] In one possible implementation, when the rotating assembly 102 is in the second state, L1 is perpendicular to L2.

[0046] In one possible implementation, each of the support structures 10 includes two rotating components 102. The two rotating components 102 are located at opposite ends of the support components 101. This further enhances the stability of the flexible screen support mechanism 110 composed of multiple support structures 10.

[0047] Of course, in other embodiments, the support structure 10 may also include only one of the rotating components 102.

[0048] Specifically, in this embodiment, please refer to Figure 1-4The support assembly 101 includes a support plate 11 and a connector 12 formed on one end of the support plate 11. The support plate 11 supports a flexible screen 120. The connectors 12 of two adjacent support structures 10 are rotatably connected via a first rotating shaft, and the rotating assembly 102 is rotatably connected to the connectors 12 via a second rotating shaft 15.

[0049] Specifically, each of the rotating components 102 includes a first rotating member 13 and a second rotating member 14, with one end of the first rotating member 13 overlapping the second rotating member 14. The first rotating member 13 and the second rotating member 14 are rotatably connected to the connecting member 12 via a second rotating shaft 15. The first rotating member 13 and the second rotating member 14 of two adjacent support structures 10 are rotatably connected via the third rotating shaft.

[0050] Please see Figure 2-4 Under the action of external force, the first rotating member 13 and the second rotating member 14 can rotate relative to the connecting member 12 and can switch between the first state and the second state.

[0051] Specifically, please refer to Figure 2-3 When L1 and L2 are collinear, the rotating component 102 is in the first state. At this time, the first rotating member 13, the second rotating member 14 and the support component 101 are on the same plane, and the two adjacent support structures 10 can rotate relative to each other so that the flexible screen support mechanism 110 can be rolled up.

[0052] Specifically, please refer to Figure 4 When L1 intersects with L2, the rotating component 102 is in the second state. At this time, the first rotating member 13, the second rotating member 14 and the support component 101 are on different planes, and the two adjacent support structures 10 cannot rotate relative to each other so that the flexible screen support mechanism 110 cannot be curled.

[0053] Specifically, please refer to Figure 5 Each connector 12 includes a connecting body 121. One end of the connecting body 121 is provided with a first connecting lug 122, and the other end is provided with two second connecting lugs 123. A first groove 127 is formed between the two second connecting lugs 123. The first connecting lug 122 of one of two adjacent support structures 10 is placed in the first groove 127 of the other, and the first connecting lug 122 of one and the two second connecting lugs 123 of the other are connected and rotated through a first rotating shaft to realize the rotational connection between two adjacent support components 101.

[0054] In this embodiment, the first connecting lug 122 and the two second connecting lugs 123 are integrally formed with the connecting body 121. In other embodiments, the first connecting lug 122 and the two second connecting lugs 123 can also be fixed to the connecting body 121 by means of adhesive, riveting or mechanical means.

[0055] The connecting body 121 is provided with two receiving slots 124. The receiving slots 124 are used for rotatable connection with the first rotating member 13 and the second rotating member 14.

[0056] In this embodiment, a first positioning hole 125 is also provided on the first connecting lug 122. The first positioning hole 125 is used to cooperate with a first rotating shaft to rotatably connect with a second connecting lug 123 of another adjacent support structure 10.

[0057] In this embodiment, two second connecting lugs 123 are arranged opposite to each other. Each second connecting lug 123 is also provided with a second positioning hole 126. The two second positioning holes 126 are positioned opposite each other. The second positioning hole 126 is used to cooperate with another first rotating shaft to rotatably connect with another adjacent first connecting lug 122 of the support structure 10. The insertion direction of the first rotating shaft in the second positioning hole 126 is consistent with the length direction of the support plate 11.

[0058] Specifically, please refer to [the relevant document] again. Figure 5 Each of the first rotating members 13 includes a first connecting portion 131, a first stepped portion 132, and two third connecting lugs 133. The first connecting portion 131, the first stepped portion 132, and the two third connecting lugs 133 are integrally formed. The first connecting portion 131 is perpendicular to the first stepped portion 132 and the two third connecting lugs 133. The first stepped portion 132 and the two third connecting lugs 133 are arranged opposite to each other. A second groove 135 is formed between the two third connecting lugs 133.

[0059] In this embodiment, the first connecting portion 131 is rotatably connected to the connecting member 12. Specifically, in this embodiment, the first connecting portion 131 is housed within one of the receiving grooves 124 and is rotatably connected to the inner walls of both receiving grooves 124 via the second rotating shaft 15. The first connecting portion 131 can switch between the first state and the second state using the second rotating shaft 15 as the rotation axis. Corresponding positioning holes (not shown) for inserting the second rotating shaft 15 are formed on the first connecting portion 131 and the inner walls of the receiving grooves 124. The second rotating shaft 15 passes through the first connecting portion 131 and is fixed to the inner walls of the two receiving grooves 124.

[0060] Each of the third connecting lugs 133 has a third positioning hole 134 formed therein. The third positioning hole 134 is engaged with a third rotating shaft and is rotatably connected to the adjacent second rotating member 14.

[0061] Specifically, please refer to [the relevant document] again. Figure 5 Each of the second rotating components 14 includes a second connecting portion 141, a second stepped portion 142, and a fourth connecting lug 143. The second connecting portion 141, the second stepped portion 142, and the fourth connecting lug 143 are integrally formed. The second connecting portion 141 is perpendicular to the second stepped portion 142 and the fourth connecting lug 143. The second stepped portion 142 and the fourth connecting lug 143 are arranged opposite to each other. The fourth connecting lug 143 of one of two adjacent rotating components 102 is placed in the second groove 135 of the other, and the fourth connecting lug 143 of one component is rotatably connected to the two third connecting lugs 133 of the other component through a third rotating shaft to achieve a rotatable connection between the two adjacent rotating components 102.

[0062] The second connecting portion 141 is rotatably connected to the connecting member 12. Specifically, in this embodiment, the second connecting portion 141 is housed within another receiving groove 124 and is rotatably connected to the inner walls of both receiving grooves 124 via the second rotating shaft 15. The second connecting portion 141 can switch between the first state and the second state using the second rotating shaft 15 as the rotation axis. Of course, corresponding positioning holes (not shown) for inserting the second rotating shaft 15 are formed on the second connecting portion 141 and the inner wall of the receiving groove 124. In this embodiment, one second rotating shaft passes through the first connecting portion 131 and the second connecting portion 141 respectively and is fixed to the inner walls of the two receiving grooves 124.

[0063] The fourth connecting lug 143 has a fourth positioning hole 144. A third rotating shaft passes through the fourth positioning hole 144 and the third positioning holes 134 on the two third connecting lugs 133 of the adjacent first rotating member 13, so that the second connecting part 141 is rotatably connected to the adjacent first rotating member 13.

[0064] Please see Figure 6-12A second aspect of this application provides a rollable electronic device 100. The rollable electronic device 100 includes a flexible screen support mechanism 110, a flexible screen 120, and a roll 130. A scroll 140 is disposed inside the roll 130. The flexible screen 120 covers the support component 101 of the flexible screen support mechanism 110. One end of the flexible screen support mechanism 110 is fixed to the scroll 140, and the other end can be wound onto the scroll 140 or pulled out of the roll 130 under external force. When the flexible screen 120 is wound onto the roller 140 along with the flexible screen support mechanism 110, L1 and L2 are coaxial, and the rotating component 102 and the support component 101 are coplanar. At this time, the rotating component 102 is in the first state. When the flexible screen 120 is pulled out of the roller 130 along with the flexible screen support mechanism 110, the rotating component 102 flips relative to the support component 101 so that L1 and L2 intersect. The rotating component 102 and the support component 101 are on different planes. At this time, the rotating component 102 is in the second state.

[0065] In one embodiment of this application, the flexible screen 120 is attached to the support plate 11 of the flexible screen support mechanism 110. In another possible embodiment, the flexible screen 120 is attached to the support plate 11 of the flexible screen support mechanism 110 using adhesive backing.

[0066] In one embodiment of this application, the spool 130 is whistle-shaped. The spool 130 includes a first housing 21 and a second housing 22. The first housing 21 and the second housing 22 constitute a receiving cavity 24 and an inlet / outlet channel 25 communicating with the receiving cavity 24. When the flexible screen support mechanism 110 moves in and out of the inlet / outlet channel 25, the first housing 21 is close to the flexible screen 120, and the second housing 22 is close to the flexible screen support mechanism 110; the spool 140 is rotatably connected to the inner wall of the receiving cavity 24. The end of the flexible screen support mechanism 110 away from the spool 140 moves in and out of the spool 130 through the inlet / outlet channel 25.

[0067] In one embodiment of this application, the reel 130 further includes at least one first guide groove 26 and one second guide groove 27. The first guide groove 26 and the second guide groove 27 are located on one side of the inlet / outlet channel 25 and at the end of the inlet / outlet channel 25 away from the receiving cavity 24.

[0068] The first guide groove 26 has a first inclined surface 261. The first inclined surface 261 is close to and faces the flexible screen 120, and the first inclined surface 261 is close to the flexible screen 120 in the direction in which the flexible screen support structure 110 is pulled out.

[0069] In one possible implementation of this application, the first inclined surface 261 is an inclined surface or a spiral surface.

[0070] The second guide groove 27 has a second inclined surface 271. The second inclined surface 271 faces away from the flexible screen support mechanism 110 of the flexible screen 120, and the second inclined surface 271 is away from the flexible screen support mechanism in the direction in which the flexible screen support structure 110 is pulled out.

[0071] In one possible embodiment of this application, the second inclined surface 271 is an inclined surface or a spiral surface.

[0072] During the process of the flexible screen support mechanism 110 being pulled out of the roll 130, the end of the rotating component 102 in the first state that is away from the roll 140 abuts against the first inclined surface 261. The rotating component 102 is subjected to a reverse force from the first inclined surface 261. Since one side of the rotating component 102 is connected to the support component 101, under the reverse force from the first inclined surface 261, the end of the rotating component 102 that is away from the support component 101 will flip from the first state to the second state.

[0073] During the process of the flexible screen support mechanism 110 being wound on the scroll 140, the end of the rotating component 102 in the second state near the scroll 140 abuts against the second inclined surface 271. The rotating component 102 is subjected to a reverse force from the second inclined surface 271. Since one side of the rotating component 102 is connected to the support component 101, under the reverse force from the second inclined surface 271, the rotating component 102 will flip from the second state to the first state.

[0074] In one embodiment of this application, the first inclined surface 261 is disposed on the first housing 21, and the second inclined surface 271 is disposed on the second housing 22.

[0075] In one embodiment of this application, the rollable electronic device 100 further includes a roll-up synchronization mechanism, a flexible screen tensioning mechanism, and a roll-up power transmission mechanism (not shown).

[0076] In one embodiment of this application, the flexible screen support mechanism 110 can be manually or automatically wound into the roll 130 or pulled out of the roll 130 by a driving device (not shown).

[0077] In one embodiment of this application, the rollable electronic device 100 can be any rollable terminal device equipped with a flexible screen, including but not limited to terminal devices such as televisions, tablets, and laptops.

[0078] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Although the preferred embodiment has been disclosed above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application.
