DETAILED DESCRIPTION

[0064] An embodiment of the present invention provides a rotating mechanism and a flexible screen device applied to a flexible screen device, which are used to provide protection measures for the flexible screen 3.

[0065] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0066] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0067] Figure 1 A schematic diagram of the structure of a flexible screen device provided by an embodiment of the present invention, Figure 2 for Figure 1 Another structural schematic diagram of the flexible screen device shown, Figure 3 for Figure 1 A schematic diagram of a closed state of a flexible screen device shown in FIG. Figure 4 for Figure 1 An exploded view of the flexible screen device is shown.

[0068] See also Figure 1-Figure 4 An embodiment of the present invention provides a flexible screen device, which includes a flexible screen 3 and a rotating mechanism.

[0069] The rotating mechanism comprises a first shell 1 and a second shell 2, wherein a flexible screen 3 is arranged on the first shell 1 and the second shell 2 of the rotating mechanism.

[0070] In the flexible screen device of the embodiment of the present invention, the first shell 1 and the second shell 2 can rotate relative to each other, and the user can unfold and close the flexible screen device by rotating the first shell 1 and the second shell 2. Figure 1 ; Schematic diagram of the closed state of the flexible screen device, please refer to Figure 3 . Users can Figure 1 The expanded state shown and Figure 3 The first housing 1 and the second housing 2 are rotated between the closed states shown.

[0071] When the first shell 1 rotates relative to the second shell 2, the flexible screen 3 also bends accordingly.

[0072] It should be understood that the flexible screen devices of the embodiments of the present invention include but are not limited to mobile phones, tablet computers, etc.

[0073] It should be understood that the flexible screen device of the embodiment of the present invention is only an exemplary description and does not constitute a specific limitation on the flexible screen device of the embodiment of the present invention.

[0074] The following is a detailed description of the rotation mechanism applied to the flexible screen device according to an embodiment of the present invention.

[0075] Figure 5 and Figure 6 A schematic structural diagram of a rotating mechanism applied to a flexible screen device provided in an embodiment of the present invention. Figure 5 and Figure 6 The rotating mechanism shown can be applied to Figure 1 On the flexible screen device shown.

[0076] in, Figure 5 After removing some parts such as the sliding panel from the rotating mechanism shown in the figure, Figure 6 The rotating mechanism shown.

[0077] See also Figure 5 and Figure 6 The rotating mechanism applied to the flexible screen device of the embodiment of the present invention includes a first shell 1, a second shell 2, a rotating shaft assembly 7, and a bending part 4.

[0078] The shaft assembly 7 is connected to the first shell 1 and the second shell 2 respectively. The shaft assembly 7 includes at least two shafts. The at least two shafts are used to guide the first shell 1 and the second shell 2 to rotate relative to each other.

[0079] One side of the bending member 4 covers at least two rotating shafts, and the other side of the bending member 4 is used to fit the side of the flexible screen 3. In this way, the bending member 4 isolates the rotating shaft of the rotating shaft assembly 7 from the flexible screen 3. Since the rotating shaft is used to guide the relative rotation of the first shell 1 and the second shell 2, when the first shell 1 and the second shell 2 rotate relative to each other, the rotating shaft of the rotating shaft assembly 7 produces relative displacement. The bending member 4 of the embodiment of the present invention isolates the rotating shaft of the rotating shaft assembly 7 from the flexible screen 3, thereby avoiding damage to the flexible screen 3 by the rotating shaft and protecting the flexible screen 3.

[0080] The bending member 4 is used to bend along with the rotation of at least two rotating shafts when the first shell 1 and the second shell 2 rotate relative to each other.

[0081] When the first shell 1 and the second shell 2 rotate relative to each other, the shaft of the shaft assembly 7 rotates and produces relative displacement. At this time, the bending member 4 bends with the rotation of the at least two shafts, so that the bending member 4 keeps covering the shaft and keeps in contact with the side of the flexible screen 3, thereby not affecting the relative rotation of the first shell 1 and the second shell 2, and also isolates the shaft of the shaft assembly 7 from the flexible screen 3, thereby protecting the flexible screen 3.

[0082] like Figure 4 and Figure 7 As shown, optionally, the bending member 4 includes a steel sheet 41 and a silicone rubber 42, and the steel sheet 41 is arranged in the silicone rubber 42. Such a bending member 4 can not only realize deformation, but also provide better protection for the flexible screen 3.

[0083] It should be understood that the bending member 4 can also be implemented in other ways, for example, the bending member 4 is made of elastic rubber, plastic or other materials.

[0084] In order to prevent the bending member 4 from arching and pulling when bending, optionally, the rotating mechanism also includes a first sliding screen plate 5.

[0085] like Figure 6 and Figure 7 As shown, one side of the first sliding screen plate 5 is connected to one side of the bending member 4 , the first sliding screen plate 5 is located between the first shell 1 and the bending member 4 , and the first sliding screen plate 5 can slide relative to the first shell 1 .

[0086] There are many ways to connect one side of the first sliding screen plate 5 and one side of the bending member 4, such as using rubber coating, gluing, etc. In the example where the bending member 4 includes a steel sheet 41 and a silicone rubber 42, the first sliding screen plate 5 can be clamped with the steel sheet 41, and then the silicone rubber 42 covers the steel sheet 41 and part of the structure of the first sliding screen plate 5.

[0087] The shaft assembly 7 further includes a first connecting rod 75, wherein the at least two shafts include a first shaft 71, the first connecting rod 75 includes a first rotating portion 751 and a first extending portion 752, the first extending portion 752 and the first rotating portion 751 are fixedly connected, the first shaft 71 passes through the first rotating portion 751, and the first extending portion 752 and the first housing 1 are movably connected. The specific implementation method of the movably connected first extending portion 752 and the first housing 1 can be a sliding connection or a gear meshing connection, etc., which is not specifically limited in the embodiment of the present invention. In this way, the connection between the first shaft 71 and the first housing 1 is realized through the first connecting rod 75.

[0088] For example, Figure 6 and Figure 7 As shown, the rotating mechanism further includes a first pressing block assembly, and the first pressing block assembly includes a first rotating gear and a second rotating gear. The first rotating gear and the second rotating gear are arranged on the first housing 1. For example, Figure 6 As shown, the first rotating gear and the second rotating gear are rotatably connected to the first housing 1 by screws respectively. The space between the first rotating gear and the second rotating gear forms a first guide track. The first extension part 752 slides relative to the first housing 1 in the first guide track.

[0089] like Figure 7 As shown, two sides of the first extension portion 752 are rack structures, and the first rotating gear and the second rotating gear are respectively meshed with the rack structures of the first extension portion 752 .

[0090] like Figure 7 and Figure 8 As shown, the first extension portion 752 is provided with a first slide groove 753, and the first sliding screen plate 5 is provided with a first fixing column 51, which is located in the first slide groove 753. The first fixing column 51 can slide relative to the first slide groove 753.

[0091] See also Figure 8 When the first housing 1 and the second housing 2 are closed, the first groove wall of the first slide groove 753 abuts against the first fixing column 51, so that the first slide groove 753 exerts a force directed to the outside of the bending member 4 on the first fixing column 51. In other words, the force points in a direction away from the bending member 4. In this way, the first slide groove 753 provides a force to stretch the bending member 4 to the bending member 4 through the first sliding screen plate 5, so that Figure 8 In the state shown, the bending member 4 fits the shaft of the shaft assembly 7, which prevents the bending member 4 from protruding relative to the shaft, thereby preventing the flexible screen 3 from being damaged by the protrusion of the bending member 4.

[0092] The side of the bending member 4 away from the first sliding screen plate 5 can be connected in a variety of ways, for example, connected to the second shell 2, or connected to the rotating shaft assembly 7, etc.

[0093] In order to make the force of the rotating mechanism balanced and better avoid the bending part 4 from protruding relative to the rotating shaft. Figure 6 , Figure 7 and Figure 8 As shown, the rotating mechanism also includes a second sliding screen plate 6.

[0094] One side of the second sliding screen plate 6 is connected to the other side of the bending member 4 . The second sliding screen plate 6 is located between the second shell 2 and the bending member 4 . The second sliding screen plate 6 can slide relative to the second shell 2 .

[0095] There are many ways to connect one side of the second sliding screen plate 6 and one side of the bending member 4, such as using rubber coating, gluing, etc. In the example where the bending member 4 includes a steel sheet 41 and a silicone rubber 42, the second sliding screen plate 6 can be clamped with the steel sheet 41, and then the silicone rubber 42 covers the steel sheet 41 and part of the structure of the second sliding screen plate 6.

[0096] The rotating shaft assembly 7 further includes a second connecting rod 76, and the at least two rotating shafts further include a second rotating shaft 72, the second connecting rod 76 includes a second rotating portion 761 and a second extending portion 762, the second extending portion 762 and the second rotating portion 761 are fixedly connected, the second rotating shaft 72 passes through the second rotating portion 761, and the second extending portion 762 is movably connected to the second housing 2. The specific implementation method of the movably connected second extending portion 762 and the second housing 2 can be a sliding connection or a gear meshing connection, etc., which is not specifically limited in the embodiment of the present invention. In this way, the connection between the second rotating shaft 72 and the second housing 2 is achieved through the second connecting rod 76.

[0097] For example, Figure 6 and Figure 7 As shown, the rotating mechanism further includes a second pressing block assembly, and the second pressing block assembly includes a third rotating gear and a fourth rotating gear. The third rotating gear and the fourth rotating gear are arranged on the second housing 2. For example, Figure 6 As shown, the third rotating gear and the fourth rotating gear are rotatably connected to the second housing 2 by screws respectively. The space between the third rotating gear and the fourth rotating gear forms a second guide track. The second extension part 762 slides relative to the second housing 2 in the second guide track.

[0098] like Figure 7 As shown, two sides of the second extension portion 762 are rack structures, and the third rotating gear and the fourth rotating gear are respectively meshed with the rack structures of the second extension portion 762 .

[0099] like Figure 7 and Figure 8 As shown, the second extension portion 762 is provided with a second slide groove 763, the second sliding screen plate 6 is provided with a second fixing column 61, and the second fixing column 61 is located in the second slide groove 763. The second fixing column 61 can slide relative to the second slide groove 763.

[0100] See also Figure 8 When the first housing 1 and the second housing 2 are closed, the second slot wall of the second slot 763 abuts against the second fixing column 61, so that the second slot 763 exerts a force on the second fixing column 61 pointing to the outside of the bending member 4. In other words, the force points to a direction away from the bending member 4. In this way, the second slot 763 provides a force to stretch the bending member 4 to the bending member 4 through the second sliding screen plate 6, so that Figure 8 In the state shown, the bending member 4 fits the shaft of the shaft assembly 7, which prevents the bending member 4 from protruding relative to the shaft, thereby preventing the flexible screen 3 from being damaged by the protrusion of the bending member 4.

[0101] The bending member 4 bends with the relative rotation of the first shell 1 and the second shell 2. Since the positions of the ends of the bending member 4 after being bent and the ends of the bending member 4 after being flattened are different, the bending member 4 is prone to bulge or protrude from the rotating shaft after being bent. In the embodiment of the present invention, the coordinated use of the first slide groove 753 and the first sliding screen plate 5, as well as the coordinated use of the second slide groove 763 and the second sliding screen plate 6, will better prevent the bending member 4 from protruding relative to the rotating shaft, and the forces on both sides of the bending member 4 are more symmetrical, which is convenient for users to operate the rotating mechanism and gives users a better operating feel.

[0102] In the example of using the first sliding screen board 5 and the second sliding screen board 6 , optionally, the rotating mechanism further includes a first elastic member 101 and a second elastic member 102 .

[0103] One end of the first elastic member 101 is connected to the first sliding screen plate 5, and the other end of the first elastic member 101 is connected to the first housing 1. The first elastic member 101 is in a stretched state to provide a pulling force between the first sliding screen plate 5 and the first housing 1.

[0104] One end of the second elastic member 102 is connected to the second sliding screen plate 6, and the other end of the second elastic member 102 is connected to the second housing 2. The second elastic member 102 is in a stretched state to provide a pulling force between the second sliding screen plate 6 and the second housing 2.

[0105] In this way, the first elastic member 101 can provide a pulling force to the first sliding screen plate 5, thereby providing a pulling force to the bending member 4. Also, the second elastic member 102 can provide a pulling force to the second sliding screen plate 6, thereby providing a pulling force to the bending member 4. Figure 8 In the closed state shown, the bending member 4 further avoids protrusion relative to the rotation axis.

[0106] In addition, if Figure 4As shown, when the first shell 1 and the second shell 2 are unfolded, that is, when the rotating mechanism is in the unfolded state, the pulling force provided by the first elastic member 101 and the second elastic member 102 can provide tension to the first shell 1 and the second shell 2, so that the first shell 1 and the second shell 2 remain in the flattened unfolded state, and when the first shell 1 and the second shell 2 are closed, the pulling force of the first elastic member 101 and the second elastic member 102 becomes the restoring force for closing the first shell 1 and the second shell 2.

[0107] It should be understood that the first elastic member 101 and the second elastic member 102 may be implemented in a variety of ways, such as a tension spring, elastic rubber, a coil spring, and the like.

[0108] For example, Figure 6 In the example shown, the first elastic member 101 and the second elastic member 102 are tension springs. A screw is connected to the first sliding screen plate 5, a screw is connected to the first housing 1, one end of the tension spring is connected to the screw on the first sliding screen plate 5, and the other end of the tension spring is connected to the screw of the first housing 1, thereby realizing the arrangement of the first elastic member 101.

[0109] A screw is connected to the second sliding screen plate 6, a screw is connected to the second shell 2, one end of the tension spring is connected to the screw on the second sliding screen plate 6, and the other end of the tension spring is connected to the screw of the second shell 2, thereby realizing the arrangement of the second elastic member 102.

[0110] In order to allow the bending member 4 to be better reset when the housing is unfolded, optionally, when the first housing 1 and the second housing 2 are unfolded, the third slot wall of the first slide slot 753 abuts against the first fixed column 51, so that the force of the first slide slot 753 acting on the first fixed column 51 offsets the pulling force of the first elastic member 101. The first slot wall and the third slot wall are the slot walls at the two ends of the first slide slot 753 that are far away from each other.

[0111] When the first shell 1 and the second shell 2 are unfolded, the fourth slot wall of the second slide slot 763 abuts against the second fixing column 61, so that the force exerted by the second slide slot 763 on the second fixing column 61 offsets the pulling force of the second elastic member 102. The second slot wall and the fourth slot wall are the slot walls at two ends of the second slide slot 763 that are far away from each other.

[0112] In this way, the pulling force of the first elastic member 101 is not conducive to the reset of the bending member 4 when the shell is unfolded, and the pulling force of the first elastic member 101 can be offset by the action of the third groove wall of the first sliding groove 753. Similarly, the action of the fourth groove wall of the second sliding groove 763 can offset the pulling force of the second elastic member 102, thereby facilitating the reset of the bending member 4 when the shell is unfolded.
