Description

Technical Field

[0002] At present, flexible screens are widely used in smart terminal devices (such as tablets, mobile phones, smart watches, laptops, etc.). The bendable characteristics of flexible screens are combined with hinge mechanisms to achieve the folding and unfolding of flexible screens, so that smart terminal devices can be used in different usage scenarios. Usually, the flexible screen is divided into three parts, two of which are connected to the hinge mechanism. The hinge mechanism is used to drive the two parts closer or farther away, so that the third part is deformed to achieve the folding and unfolding of the flexible screen. In addition, when the flexible screen is unfolded, the hinge mechanism can provide support for the flexible screen, especially for the third part of the flexible screen.

[0003] However, when the flexible screen is folded, its third part is deformed and interferes with the hinge mechanism. The third part is squeezed by the hinge mechanism, which can easily cause damage to the flexible screen. Summary of the invention

[0053] The present invention discloses a folding device, a display screen assembly and an intelligent terminal device. The folding device will not squeeze the flexible screen when folding, thereby avoiding damage to the flexible screen.

[0054] Embodiment 1

[0055] Please also read Figure 1 and Figure 2, is a structural schematic diagram of a folding device 100 provided in Embodiment 1 of the present invention, the folding device 100 includes a base 10, a movable component 11, a first folding mechanism 12 and a second folding mechanism 13, the first surface 10a of the base 10 is provided with a first mounting groove 10b, the movable component 11 is movably arranged in the first mounting groove 10b, the first folding mechanism 12 is rotatably connected to the base 10, and the second folding mechanism 13 is rotatably connected to the base 10.

[0056] Among them, Figure 1 As shown, when the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and move away from each other, the movable component 11 moves relative to the first mounting groove 10b and protrudes from or is flush with the first surface 10a, as shown in FIG. Figure 2 As shown, when the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and approach each other, the movable component 11 moves relative to the first installation groove 10b and is hidden in the first installation groove 10b.

[0057] In this embodiment, the first folding mechanism 12 and the second folding mechanism 13 can be rotatably set through the base 10 of the folding device 100, and the movable component 11 can be movably set by using the first movable groove of the base 10. When the first folding mechanism 12 and the second folding mechanism 13 are rotated relative to the base 10 and move away from each other, the movable component 11 can move relative to the first installation groove 10b and protrude or be flush with the first surface 10a. When the first folding mechanism 12 and the second folding mechanism 13 are rotated relative to the base 10 and move closer to each other, the movable component 11 can move relative to the first installation groove 10b and be hidden in the first installation groove 10b. Based on this, the first folding mechanism 12 and the second folding mechanism 13 are connected to the flexible screen, and the first folding mechanism 12 and the second folding mechanism 13 can drive the flexible screen to fold or unfold when they rotate relative to the base 10. For example, when the first folding mechanism 12 and the second folding mechanism 13 rotate away from each other relative to the base 10, the first folding mechanism 12 and the second folding mechanism 13 can drive the flexible screen to unfold. At this time, the movable part 11 protruding or flush with the first surface 10a can support the flexible screen, and when the first folding mechanism 12 and the second folding mechanism 13 rotate close to each other relative to the base 10, the first folding mechanism 12 and the second folding mechanism 13 can drive the flexible screen to fold. At this time, the movable part 11 protruding or flush with the first surface 10a can support the flexible screen. At this time, a distance is formed between the movable part 11 hidden in the first mounting groove 10b and the flexible screen. In this way, the movable part 11 will not squeeze the flexible screen when the folding device 100 is folded, thereby avoiding damage to the flexible screen.

[0058] In some embodiments, Figure 3As shown, the folding device 100 further includes a reset structure 14, which is connected to the base 10 and the movable component 11, and is used to provide a force to reset the movable component 11. In this way, the reset structure 14 is used to reset the movable component 11, so that the movable component 11 can be automatically reset to a state of being hidden in the first receiving groove, or protruding from or flush with the first surface 10a. The folding device 100 has a high degree of automation and a low degree of operation difficulty.

[0059] As an optional embodiment, when the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and move away from each other, the movable part 11 moves relative to the first mounting groove 10b under the action of the reset structure 14 and protrudes out of or is flush with the first surface 10a. When the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and move closer to each other, the first folding mechanism 12 and / or the second folding mechanism 13 drive the movable part 11 to move relative to the first mounting groove 10b and be hidden in the first mounting groove 10b. In this way, when the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and approach each other, the first folding mechanism 12 and / or the second folding mechanism 13 apply a force to the movable part 11, and when the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and move away from each other, the first folding mechanism 12 and the second folding mechanism 13 have no force on the movable part 11. At this time, the movable part 11 is not restricted by the first folding mechanism 12 and the second folding mechanism 13, and the reset structure 14 can act on the movable part 11 to reset the movable part 11 and protrude or be flush with the first surface 10a.

[0060] As another optional embodiment, when the first folding mechanism 12 and the second folding mechanism 13 rotate away from each other relative to the base 10, the first folding mechanism 12 and / or the second folding mechanism 13 drive the movable part 11 to move relative to the base 10 and protrude or be flush with the first surface 10a, and when the first folding mechanism 12 and the second folding mechanism 13 rotate toward each other relative to the base 10, the movable part 11 moves relative to the first installation groove 10b and is hidden in the first installation groove 10b under the action of the reset structure 14. In this way, when the first folding mechanism 12 and the second folding mechanism 13 rotate away from each other relative to the base 10, the first folding mechanism 12 and / or the second folding mechanism 13 exert a force on the movable part 11, and when the first folding mechanism 12 and the second folding mechanism 13 rotate toward each other relative to the base 10, the first folding mechanism 12 and the second folding mechanism 13 have no force on the movable part 11, at this time, the movable part 11 is not restricted by the first folding mechanism 12 and the second folding mechanism 13, and the reset structure 14 can act on the movable part 11 to reset the movable part 11 and hide it in the first installation groove 10b.

[0061] Thus, this embodiment provides a variety of reset modes for the reset structure 14, which can be selected according to actual conditions, and this embodiment does not specifically limit this. Specifically, this embodiment takes the reset structure 14 used to reset the movable component 11 and hidden in the first installation groove 10b as an example for explanation.

[0062] In some embodiments, Figure 1 and Figure 3 As shown, the first mounting groove 10b is provided with a through hole 10c, and the through hole 10c penetrates to the second surface 10d of the base 10, and the second surface 10d is arranged opposite to the first surface 10a. The reset structure 14 includes a locking member 141 and an elastic member 142. One end of the locking member 141 is inserted into the through hole 10c and connected to the movable component 11, and the elastic member 142 is sleeved on the locking member 141. The two ends of the elastic member 142 are respectively connected to the second surface 10d and the other end of the locking member 141. The first folding mechanism 12 and When the second folding mechanism 13 rotates relative to the base 10 and moves away from each other, the first folding mechanism 12 and / or the second folding mechanism 13 drives the movable part 11 to move relative to the first mounting groove 10b and protrude or be flush with the first surface 10a, and the telescopic part undergoes elastic deformation and has an elastic force. When the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and move closer to each other, the movable part 11 moves relative to the first mounting groove 10b under the action of the elastic force and is hidden in the first mounting groove 10b. In this way, when the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and move away from each other, the first folding mechanism 12 and the second folding mechanism 13 apply a force to the movable part 11 so that the movable part 11 moves relative to the base 10 and protrudes out of or is flush with the first surface 10a. At this time, the locking member 141 approaches the second surface 10d with the movable part 11, and the locking member 141 and the second surface 10d jointly compress the elastic member 142. The elastic member 142 is compressed and has an elastic force, which is balanced with the force applied to the movable part 11 by the first folding mechanism 12 and the second folding mechanism 13. When the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and approach each other, the first folding mechanism 12 and the second folding mechanism 13 have no force on the movable part 11. At this time, the balance between the elastic force and the force applied by the first folding mechanism 12 and the second folding mechanism 13 to the movable part 11 is broken, and the elastic force can act on the locking member 141 and the second surface 10d, so that the locking member 141 is away from the second surface 10d, so as to drive the movable part 11 to move relative to the first installation groove 10b and be hidden in the first installation groove 10b.

[0063] Optionally, the base 10 further includes a second mounting groove 10e, the second mounting groove 10e is connected to the first mounting groove 10b, and the reset structure 14 is accommodated in the second mounting groove 10e. In this way, on the one hand, by accommodating the reset structure 14 in the second mounting groove 10e, the space occupied by the reset structure 14 can be reduced, and the miniaturized design of the folding device 100 can be maintained. On the other hand, by using the second mounting groove 10e to be connected to the first mounting groove 10b, the reset structure 14 can provide a force to act on the movable component 11 to achieve the reset of the movable component 11.

[0064] For example, Figure 3 As shown, the movable component 11 includes a movable part 111, a first transmission part 112 and a second transmission part 113. The movable part 111 can be movably arranged in the first installation groove 10b, and the first transmission part 112 and the second transmission part 113 are respectively arranged on both sides of the movable part 111. When the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and move away from each other, the first folding mechanism 12 and the second folding mechanism 13 respectively push the first transmission part 112 and the second transmission part 113 to drive the movable part 11 to move relative to the first installation groove 10b and protrude or be flush with the first surface 10a. In this way, on the one hand, the movable part 111 can be movably arranged in the first installation groove 10b. When the first folding mechanism 12 and the second folding mechanism 13 respectively push the first transmission part 112 and the second transmission part 113, the first transmission part 112 and the second transmission part 113 can drive the movable part 111 to move relative to the first installation groove 10b, so that the movable part 11 protrudes or is flush with the first surface 10a. On the other hand, by pushing the first transmission part 112 and the second transmission part 113 located on both sides of the movable part 111, the movable component 11 is evenly stressed as a whole, and its movement relative to the first installation groove 10b is more stable and reliable.

[0065] In some embodiments, the base 10 includes a first shell 101 and a second shell 102 that is covered and connected with the first shell 101, the first shell 101 has a first surface 10a, and the first folding mechanism 12 and the second folding mechanism 13 are rotatably connected between the first shell 101 and the second shell 102. In this way, on the one hand, the first installation groove 10b is provided by the first shell 101 to realize the movable connection between the movable component 11 and the base 10. On the other hand, the base 10 adopts the method of covering and connecting the first shell 101 and the second shell 102, which facilitates the assembly and disassembly of the first folding mechanism 12 and the second folding mechanism 13. Specifically, by separating the first shell 101 and the second shell 102, it is convenient to install or remove the first folding mechanism 12 and the second folding mechanism 13 between the first shell 101 and the second shell 102.

[0066] Exemplarily, the first mounting groove 10b is further provided with a through groove 10f, which penetrates to a side of the first housing 101 facing the second housing 102, and the through groove 10f is used to realize the communication between the first folding mechanism 12 and the second folding mechanism 13 and the movable part 11. In this way, the first folding mechanism 12 and the movable part 11, and the second folding mechanism 13 and the movable part 11 are connected through the through groove 10f, and when the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 to move away from or approach each other, the first folding mechanism 12 and the second folding mechanism 13 can drive the movable part 11 to move relative to the first mounting groove 10b and be hidden in the first mounting groove 10b, or protrude from or be flush with the first surface 10a.

[0067] In some embodiments, Figure 4As shown, the first folding mechanism 12 includes a first rotating arm 121 and a first connecting member 122, one end of the first rotating arm 121 is rotatably connected to the base 10, and the first connecting member 122 is connected to the other end of the first rotating arm 121. The second folding mechanism 13 includes a second rotating arm 131 and a second connecting member 132, one end of the second rotating arm 131 is rotatably connected to the base 10, and the second connecting member 132 is connected to the other end of the second rotating arm 131. When the first rotating arm 121 and the second rotating arm 131 rotate away from each other relative to the base 10, the first connecting member 132 is connected to the other end of the second rotating arm 131. The connecting member 122 and the second connecting member 132 rotate relative to the base 10 and move away from each other, and the first rotating arm 121 and the second rotating arm 131 push the movable part 11 to move relative to the first mounting groove 10b and protrude or be flush with the first surface 10a. When the first rotating arm 121 and the second rotating arm 131 rotate relative to the base 10 and move closer to each other, the first connecting member 122 and the second connecting member 132 rotate relative to the base 10 and move closer to each other, and the movable part 11 moves relative to the first mounting groove 10b and is hidden in the first mounting groove 10b under the action of the reset structure 14. In this way, when the first rotating arm 121 and the second rotating arm 131 rotate relative to the base 10 and move away from each other, the first connecting member 122 and the second connecting member 132 rotate relative to the base 10 and move away from each other. At this time, the first rotating arm 121 and the second rotating arm 131 push the movable part 11 to move relative to the first mounting groove 10b and protrude or be flush with the first surface 10a. When the folding device 100 is applied to the unfolding of the flexible screen, the movable part 11 can support the flexible screen. When the first rotating arm 121 and the second rotating arm 131 rotate relative to the base 10 and approach each other, the first connecting member 122 and the second connecting member 132 rotate relative to the base 10 and approach each other. At this time, the first rotating arm 121 and the second rotating arm 131 have no force on the movable part 11, and the movable part 11 is not restricted by the first rotating arm 121 and the second rotating arm 131. The reset structure 14 can act on the movable part 11 to reset the movable part 11 and hide it in the first mounting groove 10b. When the folding device 100 is used for folding the flexible screen, the movable part 11 can form a distance between the flexible screen. In this way, the movable part 11 will not squeeze the flexible screen when the folding device 100 is folded, thereby avoiding damage to the flexible screen.

[0068] Exemplarily, the first folding mechanism 12 also includes a first connecting arm 123, one end of the first connecting arm 123 is rotatably connected to the base 10, the other end of the first connecting arm 123 is rotatably connected to the first connecting member 122, and the first connecting member 122 is slidably connected to the other end of the first rotating arm 121. The second folding mechanism 13 also includes a second connecting arm 133, one end of the second connecting arm 133 is rotatably connected to the base 10, the other end of the second connecting arm 133 is rotatably connected to the second connecting member 132, and the second connecting member 132 is slidably connected to the other end of the second rotating arm 131. When the first rotating arm 121 and the second rotating arm 131 rotate relative to the base 10 and move away from each other, the first connecting member 122 rotates relative to the base 10 with the first rotating arm 121, and the first connecting member 122 slides relative to the first rotating arm 121 in a direction close to the base 10, the first connecting arm 123 rotates relative to the base 10 and the first connecting member 122, the second connecting member 132 rotates relative to the base 10 with the second rotating arm 131, and the second connecting member 132 slides relative to the first rotating arm 121. The second rotating arm 131 slides in the direction approaching the base 10, the second connecting arm 133 rotates relative to the base 10 and the second connecting member 132, and the first rotating arm 121 and the second rotating arm 131 push the movable component 11 to move relative to the first mounting groove 10b and protrude or be flush with the first surface 10a. When the first rotating arm 121 and the second rotating arm 131 rotate relative to the base 10 and approach each other, the first connecting member 122 rotates relative to the base 10 with the first rotating arm 121, and the first connecting member 122 slides in the direction away from the base 10 relative to the first rotating arm 121, the first connecting arm 123 rotates relative to the base 10 and the first connecting member 122, the second connecting member 132 rotates relative to the base 10 with the second rotating arm 131, and the second connecting member 132 slides in the direction away from the base 10 relative to the second rotating arm 131, the second connecting arm 133 rotates relative to the base 10 and the second connecting member 132, and the movable component 11 moves relative to the first mounting groove 10b under the action of the reset structure 14 and is hidden in the first mounting groove 10b.

[0069] In this embodiment, the first rotating arm 121 and the second rotating arm 131 rotate relative to the base 10 to approach each other, so that the first connecting member 122 and the second connecting member 132 rotate relative to the base 10, and at the same time, the first connecting arm 123 is used to rotate and connect to the first connecting member 122 and the base 10, and the second connecting arm 133 is used to rotate and connect to the second connecting member 132 and the base 10. In this way, when the first connecting member 122 and the second connecting member 132 rotate relative to the base 10, the first connecting member 122 and the second connecting member 132 slide relative to the first rotating arm 121 and the second rotating arm 131 respectively, and the first connecting member 122 and the second connecting member 132 both slide in the direction away from the base 10, thereby utilizing the first connecting member 122 and the second connecting member 132 to rotate relative to the base 10. The flexible screen is connected, the first connecting member 122 and the second connecting member 132 can drive the flexible screen to achieve folding of the flexible screen, and in the process of folding, the distance between the first connecting member 122 and the second connecting member 132 and the base 10 increases, that is, the folding device 100 can be extended to avoid the folding device 100 applying pressure to the flexible screen and causing damage to the flexible screen when driving the flexible screen to achieve folding of the flexible screen, and the movable part 11 moves relative to the first mounting groove 10b under the action of the reset structure 14 and is hidden in the first mounting groove 10b, and the movable part 11 can form a distance between the flexible screen, so that the movable part 11 will not squeeze the flexible screen when the folding device 100 is folded, thereby avoiding damage to the flexible screen. When the first rotating arm 121 and the second rotating arm 131 rotate relative to the base 10 and move away from each other, the first connecting member 122 and the second connecting member 132 rotate relative to the base 10, and under the action of the first connecting arm 123 and the second connecting arm 133, the first connecting member 122 and the second connecting member 132 slide relative to the first rotating arm 121 and the second rotating arm 131 respectively, and the first connecting member 122 and the second connecting member 132 both slide in the direction away from the base 10, thereby utilizing the first connecting member 122 and the second connecting member 132 to be connected to the flexible screen, and the first connecting member 122 and the second connecting member 132 are connected to the flexible screen. The connecting member 132 can drive the flexible screen to achieve unfolding of the flexible screen, and during the unfolding process, the distance between the first connecting member 122 and the second connecting member 132 and the base 10 is reduced, that is, the folding device 100 can be shortened to avoid the folding device 100 applying a pulling force to the flexible screen and causing damage to the flexible screen when driving the flexible screen to achieve unfolding. The first rotating arm 121 and the second rotating arm 131 push the movable component 11 to move relative to the first mounting groove 10b and protrude or be flush with the first surface 10a, and the movable component 11 can support the flexible screen.

[0070] Optionally, the rotation axis of the first rotating arm 121 relative to the base 10 and the rotation axis of the first connecting arm 123 relative to the base 10 are parallel to each other and do not overlap, and the rotation axis of the second rotating arm 131 relative to the base 10 and the rotation axis of the second connecting arm 133 relative to the base 10 are parallel to each other and do not overlap. In this way, taking the first rotating arm 121 and the first connecting arm 123 as an example, when the first rotating arm 121 rotates relative to the base 10, the first connecting member 122 rotates relative to the base 10, and the first connecting arm 123 rotates relative to the base 10 at the same time. At this time, since the rotation axis of the first rotating arm 121 relative to the base 10 and the rotation axis of the first connecting arm 123 relative to the base 10 are parallel to each other and do not overlap, that is, the rotation centers do not overlap, the first rotating arm 121 and the first connecting arm 123 form a displacement difference when rotating, and the distance between the first connecting member 122 and the base 10 will change, so that when the first connecting member 122 rotates relative to the base 10, the first connecting member 122 slides relative to the first rotating arm 121. The second rotating arm 131 and the second rotating arm 131 can also utilize the displacement difference formed during the rotation, so that the second connecting member 132 rotates relative to the base 10 while the second connecting member 132 slides relative to the second rotating arm 131, which will not be repeated again.

[0071] In some embodiments, Figure 5As shown, the base 10 is provided with a first arc groove 10g and a second arc groove 10h, and the first arc groove 10g and the second arc groove 10h are both connected to the first installation groove 10b, and one end of the first connecting arm 123 is provided with an arc-shaped first bending member 123a, and the first bending member 123a is matched and connected with the first arc groove 10g so that the first connecting arm 123 can rotate relative to the base 10, and one end of the second connecting arm 133 is provided with an arc-shaped second bending member 133a, and the second bending member 133a is matched and connected with the second arc groove 10h so that the second connecting arm 133 can rotate relative to the base 10. Considering that when the first connecting member 122 and the second connecting member 132 rotate, both ends of the first connecting arm 123 and the second connecting arm 133 rotate, and a more flexible movement can be performed relative to the base 10 by rotating the two ends at a smaller angle, the first connecting arm 123 rotates at a smaller angle relative to the base 10, and the second connecting arm 133 rotates at a smaller angle relative to the base 10. Therefore, this embodiment adopts the method of using the first bending piece 123a and the first arc groove 10g to cooperate and connect to realize the rotation of the first connecting arm 123 relative to the base 10. While satisfying the smaller rotation angle of the first connecting arm 123 relative to the base 10, it can reduce the space occupied by the connection structure for realizing the rotational connection between the first connecting arm 123 and the base 10. The second bending piece 133a and the second arc groove 10hb are used to cooperate and connect to realize the rotation of the second connecting arm 133 relative to the base 10. While satisfying the smaller rotation angle of the second connecting arm 133 relative to the base 10, it can reduce the space occupied by the connection structure for realizing the rotational connection between the second connecting arm 133 and the base 10, which is conducive to the miniaturized design of the folding device 100.

[0072] Furthermore, the first arc groove 10g and the second arc groove 10h are both connected to the first mounting groove 10b, so that the first folding mechanism 12 and the movable part 11 are connected, and the second folding mechanism 13 and the movable part 11 are connected. When the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 to move away from or approach each other, the first folding mechanism 12 and the second folding mechanism 13 can drive the movable part 11 to move relative to the first mounting groove 10b and be hidden in the first mounting groove 10b, or protrude from or be flush with the first surface 10a.

[0073] As an optional embodiment, the first shell 101 or the second shell 102 is provided with a first arc groove 10g and a second arc groove 10h. In this way, the first arc groove 10g and the second arc groove 10h are formed in the first shell 101, and only the first shell 101 needs to be processed, which can reduce the processing steps and simplify the production difficulty.

[0074] As another optional implementation, Figure 6As shown, one of the first shell 101 and the second shell 102 is provided with a first protrusion 101a and a second protrusion 101b, and the other is provided with a first recessed portion 102a and a second recessed portion 102b. When the first shell 101 and the second shell 102 are covered and connected, a first arc groove 10g is formed between the first protrusion 101a and the first recessed portion 102a, and a second arc groove 10h is formed between the second protrusion 101b and the second recessed portion 102b. In this way, when assembling the folding device 100, the first bending piece 123a of the first connecting arm 123 can be placed between the first protruding portion 101a and the first recessed portion 102a, and the second bending piece 133a of the second connecting arm 133 can be placed between the second protruding portion 101b and the second recessed portion 102b, and the first shell 101 and the second shell 102 can be covered and connected, so that the first bending piece 123a and the second bending piece 133a are respectively connected with the first arc groove 10g and the second arc groove 10h, and the assembly difficulty is relatively low. When disassembling the folding device 100, the first shell 101 and the second shell 102 can be detached, and at this time, the first bending piece 123a and the second bending piece 133a can be separated from the first arc groove 10g and the second arc groove 10h, respectively, and the disassembly difficulty is relatively low.

[0075] In some embodiments, when the first rotating arm 121 and the second rotating arm 131 rotate relative to the base 10 and approach each other, a storage space is enclosed between the first connecting member 122, the base 10 and the second connecting member 132. When the first rotating arm 121 and the second rotating arm 131 rotate relative to the base 10 and move away from each other, the partial surfaces of the first connecting member 122, the base 10, the movable component 11 and the second connecting member 132 are flush to form a support plane. In this way, when the first rotating arm 121 and the second rotating arm 131 rotate relative to the base 10 and approach each other, the flexible screen is connected by the first connecting member 122 and the second connecting member 132, and the first connecting member 122 and the second connecting member 132 can drive the flexible screen to fold. At this time, the flexible screen in the folded state is located in the storage space, and the flexible screen can be accommodated and protected. When the first rotating arm 121 and the second rotating arm 131 rotate away from each other relative to the base 10, the flexible screen is connected by the first connecting member 122 and the second connecting member 132, and the first connecting member 122 and the second connecting member 132 can drive the flexible screen to unfold. At this time, the unfolded flexible screen is carried on the supporting plane, and the flatness of the flexible screen can be maintained. Specifically, the accommodating space is roughly U-shaped, which can be adapted to the folded flexible screen.

[0076] Embodiment 1 of the present invention provides a folding device 100, through the base 10 of the folding device 100, a first folding mechanism 12 and a second folding mechanism 13 can be rotatably set, and a movable component 11 can be movably set by using the first movable groove of the base 10. When the first folding mechanism 12 and the second folding mechanism 13 rotate away from each other relative to the base 10, the movable component 11 can move relative to the first installation groove 10b and protrude or be flush with the first surface 10a, and when the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and approach each other, the movable component 11 can move relative to the first installation groove 10b and be hidden in the first installation groove 10b. Based on this, the first folding mechanism 12 and the second folding mechanism 13 are connected to the flexible screen, and the first folding mechanism 12 and the second folding mechanism 13 can drive the flexible screen to fold or unfold when they rotate relative to the base 10. For example, when the first folding mechanism 12 and the second folding mechanism 13 rotate away from each other relative to the base 10, the first folding mechanism 12 and the second folding mechanism 13 can drive the flexible screen to unfold. At this time, the movable part 11 protruding or flush with the first surface 10a can support the flexible screen, and when the first folding mechanism 12 and the second folding mechanism 13 rotate close to each other relative to the base 10, the first folding mechanism 12 and the second folding mechanism 13 can drive the flexible screen to fold. At this time, the movable part 11 protruding or flush with the first surface 10a can support the flexible screen. At this time, a distance is formed between the movable part 11 hidden in the first mounting groove 10b and the flexible screen. In this way, the movable part 11 will not squeeze the flexible screen when the folding device 100 is folded, thereby avoiding damage to the flexible screen.

[0079] When the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and move away from each other, the bent portion 22 is deformed to switch the flexible screen 20 to the unfolded state, and the movable component 11 moves relative to the first mounting groove 10b and is flush with or protrudes from the first surface 10a, and the movable component 11 is supported by the bent portion 22;

[0080] When the first folding mechanism 12 and the second folding mechanism 13 rotate relative to the base 10 and approach each other, the bending part 22 is deformed to switch the flexible screen 20 to a folded state, and the movable component 11 moves relative to the first mounting groove 10b and is hidden in the first mounting groove 10b, and a distance is formed between the movable component 11 and the bending part 22.

[0081] In this embodiment, the first folding mechanism 12 and the second folding mechanism 13 are respectively connected to the first non-bending portion 21 and the second non-bending portion 23. When the first folding mechanism 12 and the second folding mechanism 13 drive the first non-bending portion 21 and the second non-bending portion 23 to approach each other, the flexible screen 20 can be folded, that is, switched to the folded state. At this time, the movable component 11 moves relative to the first mounting groove 10b and is hidden in the first mounting groove 10b, and a gap is formed between the movable component 11 and the bending portion 22. In this way, the movable component 11 will not squeeze the flexible screen 20 when the folding device 100 is folded, thereby avoiding damage to the flexible screen 20. When the first folding mechanism 12 and the second folding mechanism 13 drive the first non-bending portion 21 and the second non-bending portion 23 to move away from each other, the flexible screen 20 can be unfolded, that is, switched to the unfolded state. At this time, the movable component 11 moves relative to the first mounting groove 10b and is flush with or protrudes from the first surface 10a, and the movable component 11 is supported on the bending portion 22.

[0087] The folding and unfolding of the flexible screen can be achieved through the folding device, which can meet the different needs of users for using the smart terminal device 300. For example, when the flexible screen is in the folded state, the smart terminal device 300 occupies less space, which is convenient for carrying, storing and transporting the smart terminal device 300. When the flexible screen is in the unfolded state, it can provide a larger display area, which is convenient for users to operate the flexible screen and view the content displayed on the flexible screen.
