Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a rotating shaft mechanism and a mobile terminal. Background Technology

[0002] In the mobile terminal field, with consumers' increasing demand for larger screen sizes, flexible foldable terminals are an important trend in the future development of mobile terminals. Flexible foldable terminals typically include a flexible screen, a hinge module, and a housing. When the flexible foldable terminal is opened or closed, the hinge module provides damping force, causing the flexible screen to bend. However, with the trend towards thinner and lighter flexible foldable terminals, the space for the hinge module has been compressed to accommodate this trend. This results in poor damping and hovering functions of the hinge module, making it difficult to provide a comfortable opening and closing experience. Summary of the Invention

[0003] This application provides a pivot mechanism and a mobile terminal to increase the layout space of the pivot module.

[0004] In a first aspect, this application provides a rotating shaft mechanism, which may include a main body, a rotating assembly, and a third door panel. The rotating assembly includes a first rotating mechanism and a second rotating mechanism, which are distributed on both sides of the main body in a first direction. The first rotating mechanism includes a first swing arm, a first connecting rod, a first door panel, and a first housing support. The second rotating mechanism includes a second swing arm, a second connecting rod, a second door panel, and a second housing support. The third door panel is movably connected to the main body and is located between the first rotating mechanism and the second rotating mechanism. Specifically, the first end of the first swing arm is rotatably connected to the main body, and the first housing support is rotatably connected to the second end of the first swing arm; the second end of the second swing arm is rotatably connected to the main body, and the second housing support is rotatably connected to the second end of the second swing arm. The first door panel is fixedly connected to the first swing arm; the second door panel is fixedly connected to the second swing arm. The first end of the first connecting rod is fixedly connected to a first rotating part, which is rotatably connected to the main body. The second end of the first connecting rod is slidably connected to a first housing support. The first end of the second connecting rod is fixedly connected to a second rotating part, which is rotatably connected to the main body. The second end of the second connecting rod is slidably connected to a second housing support. When the first housing support and the second housing support rotate, the first connecting rod and the first housing support slide relative to each other, and the second connecting rod and the second housing support slide relative to each other. When the first rotating mechanism and the second rotating mechanism rotate to move away from each other, the third door panel moves in a second direction and away from the main body, the second direction being perpendicular to the first direction. When the first rotating mechanism and the second rotating mechanism rotate to the first position, the third door panel abuts against the first door panel and the second door panel and is flush with them in the second direction. When the first rotating mechanism and the second rotating mechanism rotate to move closer to each other, the third door panel moves in the second direction and closer to the main body. When the first rotating mechanism and the second rotating mechanism rotate to the second position, the third door panel forms a preset angle with the first door panel and the second door panel to form an accommodating space.

[0005] In the technical solution provided in this application, the first housing support is rotatably connected to the first swing arm, thereby providing a rotational axis when the flexible folding terminal opens and closes. The first swing arm is rotatably connected to the main body, thus also providing a rotational axis when the flexible folding terminal opens and closes. Similarly, the second housing support and the second swing arm provide a rotational axis when the flexible folding terminal opens and closes, and the second swing arm and the main body also provide a rotational axis when the flexible folding terminal opens and closes. Therefore, the pivot mechanism provides four rotational axes when the flexible folding terminal opens and closes. The housing of the flexible folding terminal can be relatively far from the main body, allowing the damping module to occupy a larger installation space on the main body. A damping module with a larger damping force can be used, and the damping and hovering functions of the damping module are ideal, improving the opening and closing experience of the flexible folding terminal and facilitating hovering at any opening angle. Using the pivot mechanism provided in this application eliminates the need to increase the thickness of the flexible folding terminal, meeting the design and usage requirements for a thinner and lighter overall flexible folding terminal. Furthermore, when the flexible folding terminal is in the flattened state, the third door panel, together with the first and second door panels, can form a flattened structure, providing flat support for the flexible screen. When the flexible folding terminal is in the closed state, the third door panel, together with the first and second door panels, can form a teardrop-shaped accommodating space to accommodate the bent portion of the flexible screen. In addition, during the process of the flexible folding terminal changing from the closed to the flattened state, the first and second lifting sections, the third and fourth lifting sections, and the fifth and sixth lifting sections can successively lift the third door panel, ensuring smooth lifting and maintaining the flatness of the third door panel when the flexible folding terminal is in the flattened state.

When the first swing arm rotates, the third lifting part rotates with the first swing arm. A fourth lifting part is fixedly connected to the side of the second swing arm near the third door panel. When the second swing arm rotates, the fourth lifting part rotates with the second swing arm. During the process of the first rotation mechanism and the second rotation mechanism rotating away from each other, when the third lifting part and the fourth lifting part rotate to the second preset position, the third lifting part and the fourth lifting part abut against the third door panel.

[0008] In one specific implementation scheme, a fifth lifting part is fixedly connected to the side of the first door panel near the third door panel.

[0011] In one specific implementation scheme, a first extension is fixedly connected to the side of the third door panel near the first link, and a second extension is fixedly connected to the side of the third door panel near the second link.

[0050] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0051] To facilitate understanding, the application scenarios of the rotating mechanism involved in this application will be explained first. The rotating mechanism provided in the embodiments of this application can be adapted to mobile terminals, such as mobile phones, tablets, etc. As one possible application scenario, the rotating mechanism provided in the embodiments of this application can be adapted to flexible folding terminals, serving as a pivot module of the flexible folding terminal, or a component of the pivot module, to realize the opening and closing of the flexible folding terminal.

[0052] Flexible folding terminals typically include structural components such as a flexible screen, a hinge module, and a housing. The housing consists of a first housing and a second housing that are movably connected. When the flexible folding terminal is opened or closed, the first and second housings rotate relative to each other, the hinge module provides damping force, and the flexible screen bends. In related technologies, to accommodate the thinner and lighter design of flexible folding terminals, the space for the hinge module is compressed. This results in poor damping and hovering functions of the hinge module, making it difficult to provide a comfortable opening and closing experience.

[0053] Based on this, this application provides a rotating shaft mechanism to increase the layout space of the rotating shaft module.

[0054] First refer to Figure 1 , Figure 1 A schematic diagram of the rotating shaft mechanism provided in an embodiment of this application is shown. Figure 1 As shown, the rotating shaft mechanism provided in this embodiment may include a main body 1 and a rotating assembly. The rotating assembly includes a first rotating mechanism and a second rotating mechanism, which are distributed on both sides of the main body in a first direction. The first direction is the direction of the rotation axis of the main body 1. See also Figure 1 The coordinate direction in the diagram is shown, with the x-axis indicating the first direction. In one possible application scenario, the pivot mechanism provided in this embodiment can be applied to a flexible folding terminal. Specifically, the first housing and the second housing of the flexible folding terminal can be fixedly connected to the first rotating mechanism and the second rotating mechanism, respectively.

[0055] The first rotating mechanism may include a first swing arm 2, a first connecting rod 10, a first door panel 8, and a first housing support 3. The first end of the first swing arm 2 can be rotatably connected to the main body 1, and the first housing support 3 can be rotatably connected to the second end of the first swing arm 2. Specifically, the first housing of the flexible folding terminal can be fixedly connected to the first housing support 3. More specifically, the first housing of the flexible folding terminal can be fixedly connected to the first housing support 3 by screws or other connecting parts. When the flexible folding terminal is opened and closed, the first housing of the flexible folding terminal can rotate relative to the main body 1, which in turn drives the first housing support 3 to rotate relative to the main body 1. The first swing arm 2 and the first housing support 3 can rotate together relative to the main body 1. When the first swing arm 2 and the first housing support 3 rotate together relative to the main body 1, the first housing support 3 can rotate relative to the first swing arm 2.

[0056] The second rotation mechanism may include a second swing arm 39, a second connecting rod 42, a second door panel 41, and a second housing support 40. The first end of the second swing arm 39 can be rotatably connected to the main body 1, and the second housing support 40 can be rotatably connected to the second end of the second swing arm 39. Specifically, the second housing of the flexible folding terminal can be fixedly connected to the second housing support 40. More specifically, the second housing of the flexible folding terminal can be fixedly connected to the second housing support 40 by screws or other connecting parts. When the flexible folding terminal is opened and closed, the second housing of the flexible folding terminal can rotate relative to the main body 1. This rotation of the second housing housing can drive the second housing support 40 to rotate relative to the main body 1. The second swing arm 39 and the second housing support 40 can rotate together relative to the main body 1. When the second swing arm 39 and the second housing support 40 rotate together relative to the main body 1, the second housing support 40 can rotate relative to the second swing arm 39.

[0057] The pivot mechanism provided in this embodiment of the application has a first housing support 3 rotatably connected to a first swing arm 2, thereby providing a rotation axis when the flexible folding terminal opens and closes. The first swing arm 2 is also rotatably connected to the main body 1, thus providing a rotation axis when the flexible folding terminal opens and closes. Similarly, the second housing support 40 and the second swing arm 39 provide a rotation axis when the flexible folding terminal opens and closes, and the second swing arm 39 and the main body 1 also provide a rotation axis when the flexible folding terminal opens and closes. Therefore, the pivot mechanism can provide four rotation axes when the flexible folding terminal opens and closes. The first and second housings of the flexible folding terminal can be relatively far from the main body 1, allowing for a larger space on the main body 1 to accommodate damping modules. Damping modules with larger damping forces can be used, resulting in ideal damping and hovering functions, improving the opening and closing experience of the flexible folding terminal and facilitating hovering at any opening angle. Furthermore, using the pivot mechanism provided in this embodiment of the application eliminates the need to increase the thickness of the flexible folding terminal, meeting the design and usage requirements for a thinner and lighter overall flexible folding terminal.

[0058] Figure 2 A schematic diagram of the structure of the first swing arm of the rotating shaft mechanism provided in the embodiment of this application is shown. Figure 3 A schematic diagram of the main body of the rotating shaft mechanism provided in an embodiment of this application is shown. (See also...) Figure 2 and Figure 3 As shown, in one possible implementation, the first end of the first swing arm 2 can be rotatably connected to the main body 1 via a first arc-shaped rotating assembly, allowing for relatively stable relative rotation between the first swing arm 2 and the main body 1. The first arc-shaped rotating assembly may include a first arc-shaped groove 4 and a first arc-shaped slider 5. Figure 2 An example is shown where the first arc-shaped groove 4 is located at the first end of the first swing arm 2. Figure 3 The example illustrates a first arc-shaped slider 5 mounted on the main body 1. Alternatively, a first arc-shaped groove 4 can be mounted on the main body 1, and the first arc-shaped slider 5 can be mounted at the first end of the first swing arm 2. The first arc-shaped slider 5 is movably connected within the first arc-shaped groove 4, enabling a rotational connection between the first swing arm 2 and the main body 1. When the flexible folding terminal opens and closes, the first arc-shaped groove 4 and the first arc-shaped slider 5 cooperate to provide a rotational axis between the first swing arm 2 and the main body 1. In a specific implementation, the first swing arm 2 and the main body 1 can be rotatably connected via two first arc-shaped rotating components. These two first arc-shaped rotating components can be coaxially arranged to improve the stability of the relative rotation between the first swing arm 2 and the main body 1.

[0059] Figure 4 A schematic diagram of the structure of the first housing support of the rotating shaft mechanism provided in an embodiment of this application is shown. (See also...) Figure 2 and Figure 4As shown, in one possible implementation, the second end of the first housing support 3 and the first swing arm 2 can be rotatably connected via a second arc-shaped rotating assembly. Similarly, the relative rotation between the first housing support 3 and the first swing arm 2 can be relatively stable. The second arc-shaped rotating assembly may include a second arc-shaped groove 6 and a second arc-shaped slider 7. Figure 2 An example is shown where the second arc-shaped groove 6 is located at the second end of the first swing arm 2. Figure 4 An example is shown where the second arc-shaped slider 7 is mounted on the first housing support 3. Alternatively, the second arc-shaped groove 6 can be mounted on the first housing support 3, and the second arc-shaped slider 7 can be mounted on the second end of the first swing arm 2. The second arc-shaped slider 7 is movably connected within the second arc-shaped groove 6, enabling a rotational connection between the first housing support 3 and the first swing arm 2. When the flexible folding terminal opens and closes, the second arc-shaped groove 6 and the second arc-shaped slider 7 cooperate to provide another rotational axis for the first housing support 3 and the first swing arm 2. In a specific implementation, the first housing support 3 and the first swing arm 2 can be rotatably connected via two second arc-shaped rotating components. The two second arc-shaped rotating components can be coaxially arranged to improve the stability of the relative rotation between the first housing support 3 and the first swing arm 2.

[0060] Figure 5 An exploded structural diagram of the rotating shaft mechanism provided in an embodiment of this application is shown. (Combined with...) Figure 1 and Figure 5 As shown, the first end of the second swing arm 39 is rotatably connected to the main body 1 via a third arc-shaped rotating assembly. The third arc-shaped rotating assembly includes a third arc-shaped groove and a third arc-shaped slider, which are respectively disposed on the first end of the second swing arm 39 and the main body 1. The third arc-shaped slider is movably connected within the third arc-shaped groove. The second housing support 40 is rotatably connected to the second end of the second swing arm 39 via a fourth arc-shaped rotating assembly. The fourth arc-shaped rotating assembly includes a fourth arc-shaped groove and a fourth arc-shaped slider, which are respectively disposed on the second end of the second swing arm 39 and the second housing support 40. The fourth arc-shaped slider is movably connected within the fourth arc-shaped groove. The specific details of the third and fourth arc-shaped rotating assemblies can be found in the first and second arc-shaped rotating assemblies, and will not be elaborated further.

[0061] like Figure 5 As shown, the first door panel 8 can be fixedly connected to the first swing arm 2. When the first swing arm 2 rotates, the first door panel 8 can rotate together with the first swing arm 2. Specifically, the first door panel 8 can be fixedly connected to the first swing arm 2 using screws or other connecting parts. The second door panel 41 can be fixedly connected to the second swing arm 39. When the second swing arm 39 rotates, the second door panel 41 can rotate together with the second swing arm 39. Specifically, the second door panel 41 can be fixedly connected to the second swing arm 39 using screws or other connecting parts.

[0062] The first link 10 and the second link 42 are parallel to each other about a first direction. The first end of the first link 10 can be fixedly connected to a first rotating part 13, which is rotatably connected to the main body 1. The second end of the first link 10 can be movably connected to the first housing support 3. The first end of the second link 42 can be fixedly connected to a second rotating part 43, which is rotatably connected to the main body 1. The second end of the second link 42 can be movably connected to the second housing support 40. When the first housing support 3 and the second housing support 40 rotate, the first link 10 can slide relative to the first housing support 3, and the first link 10 can rotate with the first housing support 3. Similarly, the second link 42 can slide relative to the second housing support 40, and the second link 42 can rotate with the second housing support 40.

[0063] As one possible implementation, the pivot mechanism provided in this application embodiment may further include a damping component 9 to provide damping force when the flexible folding terminal opens and closes. Figure 1 As shown, the damping assembly 9 may include a connected cam 11, a limiting bracket 12, and an elastic module 16. The limiting bracket 12 may be fixedly connected to the main body 1. The connected cam 11 may be disposed in a first direction between the first link 10 and the second link 42 and the limiting bracket 12. An elastic module 16 may be disposed between the connected cam 11 and the limiting bracket 12, and both ends of the elastic module 16 may abut against the connected cam 11 and the limiting bracket 12 respectively. When the connected cam 11 is away from the first link 10 and the second link 42, the elastic module 16 can provide damping force; when the connected cam 11 is close to the first link 10 and the second link 42, the elastic module 16 can provide driving force. When the flexible folding terminal is in a closed state, the elastic module 16 may be configured to be in a compressed state. In a specific implementation, the elastic module 16 may be a spring.

[0064] In a specific implementation, a damping part can be provided between the integrated cam 11 and the first rotating part 13 and the second rotating part 43. When the first housing support 3 and the second housing support 40 rotate, the first connecting rod 10 and the second connecting rod 42 rotate, and the first rotating part 13 and the second rotating part 43 rotate relative to the integrated cam 11. The damping part can provide damping force, and the integrated cam 11 can move closer to or further away from the first connecting rod 10 and the second connecting rod 42. In practical applications, when the flexible folding terminal changes from a flattened state to a closed state, the integrated cam 11 can be configured to move away from the first connecting rod 10 and the second connecting rod 42; when the flexible folding terminal changes from a closed state to a flattened state, the integrated cam 11 can be configured to move closer to the first connecting rod 10 and the second connecting rod 42.

[0065] In a specific implementation, the damping part may include a first cam surface 14 and a second cam surface 15. The first cam surface 14 may be respectively disposed on the side of the first rotating part 13 and the second rotating part 43 facing the integrated cam 11, and the second cam surface 15 may be disposed on the side of the integrated cam 11 facing the first rotating part 13 and the second rotating part 43. The first cam surface 14 and the second cam surface 15 can abut against each other. When the first connecting rod 10 and the second connecting rod 42 rotate, the first cam surface 14 and the second cam surface 15 can slide relative to each other, thereby providing damping force. Furthermore, the integrated cam 11 can slide along a first direction and move closer to or away from the first connecting rod 10 and the second connecting rod 42. Specifically, the first cam surface 14 may include a plurality of first protrusions, and the second cam surface 15 may include a plurality of second protrusions. For example, the first cam surface 14 may include three first protrusions, and the second cam surface 15 may include three second protrusions. The relative sliding of multiple first protrusions and multiple second protrusions can provide a larger damping force, and the stress on each first protrusion and second protrusion can be smaller, resulting in less wear, which can improve the service life of the damping component 9 and reduce the damping force attenuation.

[0066] In a specific implementation, the damping assembly may further include a first limiting shaft 17, which is arranged along a first direction. The first connecting rod 10 and the second connecting rod 42, along with the integrated cam 11, can be connected to the limiting bracket 12 via the first limiting shaft 17. Specifically, the first connecting rod 10 and the integrated cam 11 can be connected to the limiting bracket 12 via one first limiting shaft 17, and the second connecting rod 42 and the integrated cam 11 can be connected to the limiting bracket 12 via another first limiting shaft 17. Taking the connection of the first connecting rod 10 and the integrated cam 11 to the limiting bracket 12 via one first limiting shaft 17 as an example, both ends of the first limiting shaft 17 can pass through the first connecting rod 10 and the limiting bracket 12, respectively. One end of the first limiting shaft 17 extending out of the first connecting rod 10 can be fixedly or rotatably connected to the first connecting rod 10 via a limiting plate or the like. Similarly, one end of the first limiting shaft 17 extending out of the limiting bracket 12 can also be fixedly or rotatably connected to the limiting bracket 12 via a limiting plate or the like, thereby restricting the movement of the first limiting shaft 17 along its own axial direction. When the elastic module 16 is a spring, the elastic module 16 can be sleeved on the first limiting shaft 17.

[0067] In specific implementation, a first limiting groove 18 can be provided on the first housing support 3, and the second end of the first connecting rod 10 can be slidably connected in the first limiting groove 18. The first limiting groove 18 can be a groove extending in a straight line, that is, the first limiting groove 18 can be a straight groove structure. When the first housing support 3 rotates relative to the main body 1, it can drive the first connecting rod 10 to rotate relative to the main body 1, and the first connecting rod 10 can slide along the extending direction of the first limiting groove 18, that is, the first connecting rod 10 can extend and retract relative to the first housing support 3. Specifically, a recess 19 can be provided in the first limiting groove 18, and a protrusion 20 can be provided at the second end of the first connecting rod 10. The protrusion 20 can be engaged in the recess 19, and the relative sliding between the first connecting rod 10 and the first limiting groove 18 can be relatively stable. The second housing support 40 may be provided with a second limiting slide groove, and the second end of the second connecting rod 42 may be slidably connected in the second limiting slide groove. The second limiting slide groove can be referred to the first limiting slide groove for details, which will not be elaborated here.

[0068] Figure 6 A diagram illustrating a possible application scenario of the rotating shaft mechanism provided in an embodiment of this application is shown. For example... Figure 6 As shown, in practical applications, the first housing 22 and the second housing 23 of the flexible folding terminal can be fixedly connected to the rotating shaft mechanism 24, respectively. In specific implementations, combined with... Figure 5 As shown, the two shells of the flexible folding terminal can be fixedly connected to the first shell support 3 and the second shell support 40, respectively.

[0069] Figure 7 This diagram illustrates a possible application scenario of the rotating shaft mechanism provided in an embodiment of this application. Figure 7 The example illustrates a flexible folding terminal folded in the area where the pivot mechanism 24 is located, and the flexible folding terminal is in a closed state. At this time, the first housing 22 and the second housing 23 can be parallel to each other. For the entire flexible folding terminal, the area where the pivot mechanism 24 is located can be referred to as the pivot area of ​​the entire flexible folding terminal.

[0070] In specific implementation, refer to Figure 5 As shown, the rotating mechanism may further include a third door panel 21, which is movably connected to the main body 1 and can be located between the first rotating mechanism and the second rotating mechanism. When the first rotating mechanism and the second rotating mechanism rotate relative to the main body 1 to move away from each other, that is, when the flexible folding terminal changes from a closed state to a flattened state, the third door panel 21 can move in a second direction perpendicular to the first direction and move away from the main body 1. See also Figure 5In the coordinate system, the x-axis represents the first direction, and the z-axis represents the second direction. When the first and second rotating mechanisms rotate to the first position, which corresponds to the position of the pivot mechanism when the flexible folding terminal is in a flattened state, the third door panel 21 can abut against the first door panel 8 and the second door panel 41 and be flush with it in the second direction. Therefore, when the flexible folding terminal is in a flattened state, there is no gap in the pivot area, and the two shells of the flexible folding terminal can be seamlessly joined through the first door panel 8, the second door panel 41, and the third door panel 21, providing flat support for the flexible screen and ensuring its flatness. When the first and second rotating mechanisms rotate relative to the main body 1 to move closer to each other, i.e., when the flexible folding terminal changes from a flattened state to a closed state, the third door panel 21 can move in the second direction and approach the main body 1, forming a receiving space with the first door panel 8 and the second door panel 41. Specifically, when the first and second rotating mechanisms rotate to the second position (which corresponds to the position of the pivot mechanism when the flexible folding terminal is in the closed state), the third door plate 21 can form a preset angle with the first door plate 8 and the second door plate 41 to create a receiving space. For example, a teardrop-shaped receiving space can be formed, meaning the pivot area forms a teardrop-shaped receiving space. This allows the receiving space to accommodate the bent portion of the flexible screen when the flexible folding terminal is in the closed state, releasing the bending stress of the flexible screen, extending its lifespan, and ensuring the flexible screen length remains constant during opening and closing, thus improving the overall structural stability of the flexible folding terminal. In practice, multiple third door plates 21 can be used, and these plates can be fixed together to achieve synchronous movement.

[0071] Figure 8 A schematic diagram of the rotating shaft mechanism provided in an embodiment of this application is shown. Figure 8 As shown, the third door panel 21 is located between the first door panel 8 and the second door panel 41. When the first rotating mechanism and the second rotating mechanism are at a first preset angle, for example, when the corresponding flexible folding terminal is in a flattened state, the third door panel 21 abuts against the first door panel 8 and the second door panel 41 and is flush with them.

[0072] Figure 9 A diagram showing a certain state of the rotating shaft mechanism provided in an embodiment of this application is illustrated. For example... Figure 9 As shown, when the first rotating mechanism and the second rotating mechanism are at a first preset angle, for example, when the flexible folding terminal is in a flattened state, the third door panel 21 can abut against and be flush with the first door panel 8 and the second door panel 41. At this time, the third door panel 21, the first door panel 8 and the second door panel 41 can form a flattened structure, which can achieve flat support for the flexible screen 25 of the flexible folding terminal.

[0073] Figure 10 Another state diagram of the rotating shaft mechanism provided in an embodiment of this application is shown. For example... Figure 10 As shown, when the first rotating mechanism and the second rotating mechanism are at a second preset angle, for example, when the flexible folding terminal is in a closed state, the third door panel 21, the first door panel 8, and the second door panel 41 can form a teardrop-shaped accommodating space that can accommodate the bent portion of the flexible screen 25 of the flexible folding terminal.

[0074] Figure 11 A cross-sectional view of a rotating shaft mechanism provided in an embodiment of this application is shown. For example... Figure 11 As shown, in one possible implementation, the rotating mechanism may further include a reset mechanism. Specifically, the main body 1 may have a first guide hole. The reset mechanism may pass through the first guide hole and be fixedly connected to the third door panel 21. Specifically, the reset mechanism may be fixedly connected to the side of the third door panel 21 facing the main body 1. When the flexible folding terminal changes from a closed state to a flattened state, that is, when the first rotating mechanism and the second rotating mechanism rotate relative to the main body 1 to move away from each other, the third door panel 21 moves in a second direction and away from the main body 1.

[0075] Figure 12 A cross-sectional view of another state of the rotating shaft mechanism provided in an embodiment of this application is shown. For example... Figure 12 As shown, when the flexible folding terminal changes from a flattened state to a closed state, that is, when the first rotating mechanism and the second rotating mechanism rotate relative to the main body 1 to move closer to each other, the reset mechanism can drive the third door panel 21 to move in the second direction and move closer to the main body 1.

[0076] In specific implementation, refer to the following: Figure 11 and Figure 12 As shown, the reset mechanism may include a first guide post 27, a limiting member 28, and an elastic member 29. The first guide post 27 may pass through a first guide hole, and its first end may be fixedly connected to the third door panel 21. The limiting member 28 may be fixedly connected to the second end of the first guide post 27. Specifically, the limiting member 28 may be a stud, and it may be detachably connected to the first guide post 27 via a threaded structure. One end of the elastic member 29 may abut against the limiting member 28, and the other end may abut against the main body 1. Specifically, the elastic member 29 may be a spring, and it may be sleeved on the first guide post 27. When the first rotating mechanism and the second rotating mechanism rotate relative to the main body 1 to move closer to each other, the elastic member 29 may drive the limiting member 28 to move in the second direction and move closer to the main body 1, thereby driving the third door panel 21 to move in the second direction and move closer to the main body 1.

[0077] In practical applications, when the flexible folding terminal is in a flattened state, the elastic element 29 can be configured to be in a compressed state. Thus, during the process of the flexible folding terminal changing from a flattened state to a closed state, the elastic element 29 can extend to provide driving force, thereby driving the third door panel 21 to move in the second direction and approach the main body 1.

[0078] Figure 13 A schematic diagram of the rotating shaft mechanism provided in an embodiment of this application is shown in a certain cross-section. (Combined with...) Figure 1 and Figure 13 As shown, the first guide hole 26 can be provided on the limiting bracket 12. The limiting member 28 and the third door panel 21 can be arranged on the upper and lower sides of the limiting bracket 12 respectively. The elastic member 29 can be provided between the limiting member 28 and the limiting bracket 12, with one end of the elastic member 29 abutting against the limiting member 28 and the other end of the elastic member 29 abutting against the limiting bracket 12. In a specific implementation, a second guide post 30 can be fixedly connected to the side of the third door panel 21 that is fixedly connected to the first guide post 27. A second guide hole 31 can be provided on the main body 1, and the second guide post 30 can be movably connected in the second guide hole 31, thereby improving the stability of the third door panel 21 during the lifting and resetting process.

[0079] As one possible implementation, the first and second links of the damping assembly can be rotatably connected by a transmission gear set, which can achieve the synchronicity of the rotation of the first and second links. That is, when the first link rotates, the second link can be driven to rotate by the same angle through the transmission gear set, thereby ensuring the synchronicity of the rotation of the first and second shells of the flexible folding terminal.

[0080] Figure 14 A schematic diagram of the rotating shaft mechanism provided in an embodiment of this application is shown in another cross-section. For example... Figure 14 As shown, the first rotating part 13 of the first connecting rod 10 and the second rotating part 43 of the second connecting rod 42 can be rotatably connected by a transmission gear set. Specifically, the transmission gear set may include at least two meshing transmission gears 32, with the axial direction of the transmission gears 32 arranged along a first direction. More specifically, the transmission gear set may include an even number of meshing transmission gears 32, for example, the transmission gear set may include two meshing transmission gears 32, which can make the first connecting rod 10 and the second connecting rod 42 move closer or further apart.

[0081] In the transmission gear set, the transmission gear 32 near the first rotating part 13 can be rotatably connected to the first rotating part 13. In a specific implementation, the first rotating part 13 has a first circumferential surface surrounding its own rotation axis, and the first circumferential surface can be provided with a first tooth structure, which can mesh with the transmission gear 32 to realize the transmission between the first rotating part 13 and the transmission gear 32.

[0082] In the transmission gear set, the transmission gear 32 near the second rotating part 43 can be rotatably connected to the second rotating part 43. Specifically, the second rotating part 43 has a second circumferential surface surrounding its own rotation axis. This second circumferential surface can be provided with a second tooth structure, which can mesh with the transmission gear 32 to realize the transmission between the second rotating part 43 and the transmission gear 32. This achieves the transmission between the first rotating part 13 and the second rotating part 43. Specifically, the first circumferential surface of the first rotating part 13 can be provided with multiple first tooth structures, which can be distributed on the first circumferential surface of the first rotating part 13 in a matching manner according to the tooth distribution of the transmission gear 32. Similarly, the second circumferential surface of the second rotating part 43 can be provided with multiple second tooth structures.

[0083] In specific implementation, such as Figure 1 As shown, the damping assembly may further include a second limiting shaft 33, which may be arranged parallel to the first limiting shaft 17, i.e., the second limiting shaft 33 may be arranged along a first direction. One end of the second limiting shaft 33 may be connected to the limiting bracket 12, and the other end of the second limiting shaft 33 may pass through the integrated cam 11. The transmission gear 32 may be rotatably connected to the second limiting shaft 33, thereby connecting the transmission gear 32 to the limiting bracket 12 through the second limiting shaft 33 to achieve positioning of the transmission gear 32. In specific implementation, the length of the second limiting shaft 33 may be shorter than the length of the first limiting shaft 17. One end of the second limiting shaft 33 may be set in the blind hole of the limiting bracket 12, i.e., the second limiting shaft 33 may not penetrate the limiting bracket 12, and the other end of the second limiting shaft 33 may be set in the blind hole of the main body 1. The second limiting shaft 33 may be fixedly connected or rotatably connected to the limiting bracket 12.

[0084] In practical implementation, there can be multiple elastic modules 16. Each elastic module 16 can abut its two ends against the integrated cam 11 and the limiting bracket 12, respectively. Multiple elastic modules 16 can collectively provide damping force or driving force. When the elastic module 16 is a spring, multiple elastic modules 16 can be respectively sleeved on the first limiting shaft 17 and the second limiting shaft 33. Specifically, four elastic modules 16 can be arranged to provide greater damping force and improve the opening and closing experience of the flexible folding terminal.

[0085] In a specific implementation, the rotating shaft mechanism can have multiple damping components, such as two damping components. The two damping components can be arranged along a first direction. The limiting brackets 12 of the two damping components can be arranged close to each other, and the integrated cams 11 of the two damping components can be arranged far apart from each other. Specifically, the two damping components can share a single limiting bracket 12.

[0086] Figure 15 A partial structural schematic diagram of the rotating shaft mechanism provided in an embodiment of this application is shown. For example... Figure 15 As shown, in one possible implementation, a first lifting part 34 can be fixedly connected to the first rotating part 13. Specifically, the first lifting part 34 can be fixedly connected to the side of the first rotating part 13 away from the integrated cam. When the first rotating part 13 rotates, the first lifting part 34 can rotate with the first rotating part 13. Similarly, a second lifting part 44 can be fixedly connected to the second rotating part 43. During the process of the flexible folding terminal changing from a closed state to a flattened state, when the first lifting part 34 and the second lifting part 44 rotate to a first preset position, the first lifting part 34 and the second lifting part 44 can respectively abut against the third door panel 21. When the first lifting part 34 and the second lifting part 44 continue to rotate, the first lifting part 34 and the second lifting part 44 can jointly drive the third door panel 21 to move away from the main body, that is, the first lifting part 34 and the second lifting part 44 can lift the third door panel 21.

[0087] Figure 16 A schematic diagram of the structure of the third door panel of the rotating shaft mechanism provided in an embodiment of this application is shown. Figure 16 As shown. A first extension 35 can be fixedly connected to the side of the third door panel 21. Specifically, the first extension 35 can be fixedly connected to the side of the third door panel 21 near the first connecting rod. The first extension 35 can be integrally formed with the third door panel 21. Similarly, a second extension 45 can be fixedly connected to the side of the third door panel 21 near the second connecting rod. Figure 15 and Figure 16 As shown, when the first lifting part 34 and the second lifting part 44 rotate to the first preset position, the first lifting part 34 can abut against the first extension part 35, and the second lifting part 44 can abut against the second extension part 45. Through the cooperation of the first lifting part 34 and the first extension part 35 and the second lifting part 44 and the second extension part 45, the third door panel 21 is lifted during the process of the flexible folding terminal changing from a closed state to a flattened state. Figure 16 The image shows a first guide post 27 and a second guide post 30, which are located on the same side of the third door panel 21.

[0088] Figure 17 A partial structural schematic diagram of the rotating shaft mechanism provided in an embodiment of this application is shown. For example... Figure 17As shown, in one possible implementation, a third lifting part 36 can be fixedly connected to the side of the first swing arm 2 near the third door panel 21. When the first swing arm 2 rotates, the third lifting part 36 can rotate with the first swing arm 2. Similarly, a fourth lifting part 46 can be fixedly connected to the side of the second swing arm 39 near the third door panel 21. During the process of the flexible folding terminal changing from a closed state to a flattened state, when the third lifting part 36 and the fourth lifting part 46 rotate to the second preset position, the third lifting part 36 and the fourth lifting part 46 can respectively abut against the third door panel 21. When the third lifting part 36 and the fourth lifting part 46 continue to rotate, the third lifting part 36 and the fourth lifting part 46 can jointly drive the third door panel 21 to move in the second direction and away from the main body, that is, the third lifting part 36 and the fourth lifting part 46 can lift the third door panel 21. Figure 16 As shown, area a on the third door panel 21 can be the area where the third lifting part 36 abuts against the third door panel 21, and the area symmetrical to area a can be the area where the fourth lifting part 46 abuts against the third door panel 21.

[0089] Figure 18 A partial structural schematic diagram of the rotating shaft mechanism provided in an embodiment of this application is shown. For example... Figure 18 As shown, in one possible implementation, a fifth lifting part 37 can be fixedly connected to the side of the first door panel 8 near the third door panel 21. When the first door panel 8 rotates, the fifth lifting part 37 can rotate with the first door panel 8. Similarly, a sixth lifting part 47 can be fixedly connected to the side of the second door panel 41 near the third door panel 21. During the process of the flexible folding terminal changing from a closed state to a flattened state, when the fifth lifting part 37 and the sixth lifting part 47 rotate to a third preset position, the fifth lifting part 37 and the sixth lifting part 47 can respectively abut against the third door panel 21. When the fifth lifting part 37 and the sixth lifting part 47 continue to rotate, the fifth lifting part 37 and the sixth lifting part 47 can jointly drive the third door panel 21 to move in the second direction and away from the main body, that is, the fifth lifting part 37 and the sixth lifting part 47 can lift the third door panel 21. Figure 16 As shown, area b on the third door panel 21 can be the area where the fifth lifting part 37 abuts against the third door panel 21, and the area symmetrical to area b can be the area where the sixth lifting part 47 abuts against the third door panel 21.

[0090] During the process of the flexible folding terminal changing from a closed state to a flattened state, the first lifting part 34 and the second lifting part 44, the third lifting part 36 and the fourth lifting part 46, and the fifth lifting part 37 and the sixth lifting part 47 can be configured to successively participate in lifting the third door panel 21. When the flexible folding terminal is opened to the flattened state, the third door panel 21 is lifted into place, and the third door panel 21 abuts against the first door panel 8 and the second door panel 41 and is flush with them in the second direction, thus achieving flat support for the screen. The arrangement of multiple lifting parts can ensure that the third door panel 21 is lifted smoothly and can also ensure the flatness of the third door panel 21 when the flexible folding terminal is in the flattened state.

[0091] In a specific implementation, the rotating shaft mechanism can have multiple rotating components, such as two rotating components. The two rotating components can be arranged along a first direction, and can be respectively positioned close to both ends of the flexible folding terminal in the first direction. The two rotating components can jointly connect the two housings of the flexible folding terminal. Specifically, the two rotating components can be arranged symmetrically.

[0092] As one possible implementation method, refer to Figure 5 As shown, the rotating mechanism provided in this embodiment may further include a back cover 38, and the main body 1 may be fixedly connected to the back cover 38. Specifically, the main body 1 may be fixedly connected to the back cover 38 by screws or other connecting parts. The back cover 38 and the third door panel 21 may be located on opposite sides of the main body 1 in the second direction. When the flexible folding terminal is in a flattened state, the main body 1, the rotating assembly, and the damping assembly may be located between the flattened structure formed by the first door panel 8, the second door panel 41, and the third door panel 21 and the back cover 38.

[0093] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
