Description

Technical Field

[0001] This application relates to the field of electronic technology, specifically to a rotating shaft mechanism, a folding housing, and an electronic device. Background Technology

[0002] As flexible display technology matures, foldable electronic devices, which combine large-screen display and portability, are gaining popularity. However, a key challenge in foldable electronic devices is the low motion precision of their hinge structure, making it difficult to meet the design requirements for hinge motion trajectories. Summary of the Invention

[0003] This application provides a rotating shaft mechanism, a folding housing, and an electronic device that can improve motion accuracy.

[0004] In a first aspect, this application provides a rotating shaft mechanism, comprising: Base; The first connecting seat is located on one side of the base; A first rotating member is located between the base and the first connecting seat. One end of the first rotating member is rotatably connected to the base, and the other end of the first rotating member is slidably connected to the first connecting seat. The first rotating member and the first connecting seat can move relative to the base to switch between a first state and a second state. A first driving member is located on one side of the base. One end of the first driving member is rotatably connected to one of the base and the first connecting seat, and the other end of the first driving member is rollably connected to the other of the base and the first connecting seat. When the first connecting seat moves relative to the base, the first driving member moves relative to the base. A first support member is located on one side of the base. One end of the first support member is rotatably connected to the first connecting seat and rollwise connected to the first driving member. Alternatively, the first support member is rollwise connected to the first connecting seat and rotatably connected to the first driving member. When the first connecting seat and the first driving member move relative to the base, the first support member moves relative to the base.

[0005] Secondly, this application also provides a folding housing, including a first housing, a second housing, and the aforementioned rotating shaft mechanism. The first housing is fixedly connected to the first connecting seat, and the second housing is fixedly connected to the base or rotatably connected to the base. The first housing rotates relative to the base to achieve flattening and folding.

[0006] Thirdly, this application also provides a folding housing, including a first housing, a second housing, and the aforementioned rotating shaft mechanism. The first housing is fixedly connected to the first connecting seat, and the second housing is fixedly connected to the second connecting seat of the rotating shaft mechanism. The first housing and the second housing rotate relative to the base to realize the flattening and folding of the folding housing.

[0007] Fourthly, this application also provides an electronic device, including a flexible display screen and the aforementioned folding housing. The flexible display screen covers the first housing, the pivot mechanism, and the second housing. The flexible display screen includes a first non-bending area, a bending area, and a second non-bending area arranged sequentially. The first non-bending area is fixedly connected to the first housing, and the second non-bending area is fixedly connected to the second housing.

[0008] The rotating shaft mechanism provided in this application includes a base, a first connecting seat, a first rotating member, a first driving member, and a first supporting member. Since the first connecting seat is located on one side of the base and the first rotating member is located between the first connecting seat and the base, one end of the first rotating member is rotatably connected to the base and the other end is slidably connected to the first connecting seat, so that the first connecting seat and the first rotating member can only slide relative to each other and cannot rotate. This is beneficial for controlling the movement of the first connecting seat and the first rotating member relative to the base and improving the movement accuracy of the first connecting seat and the first rotating member when switching between the first state and the second state. Because one end of the first driving member is rotatably connected to one of the base and the first connecting seat, and the other end of the first driving member is rollingly connected to the other of the base and the first connecting seat, and the first support member is rotatably connected to the first connecting seat and rollingly connected to the first driving member, or the first support member is rollingly connected to the first connecting seat and rotatably connected to the first driving member, the first support member can move relative to the base under the drive of the first connecting seat and the first driving member. This facilitates the support function of the first support member in different states, enabling it to reduce the folding gaps of folding shells and electronic devices when applied to them, thereby improving the appearance and supporting the flexible display screen of the electronic device. Furthermore, the first driving member is rollingly connected to one of the base and the first connecting seat, meaning the first driving member can slide and rotate relative to one of the base and the first connecting seat; similarly, the first support member is rollingly connected to one of the first connecting seat and the first driving member, meaning the first support member can slide and rotate relative to one of the first connecting seat and the first driving member. This facilitates the realization of multiple movement trajectories for the first support member, meeting design requirements and further improving the movement accuracy of the first support member.

[0014] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the electronic device 100 provided in the embodiments of this application when it is in a flattened state. Figure 2 This is a schematic diagram of the structure of the electronic device 100 provided in this application when it is in a folded state. The electronic device 100 provided in this application can be a foldable mobile phone, a foldable tablet, a foldable computer, a foldable wearable device, a foldable vehicle device, etc. A foldable mobile phone is used as an example in this application embodiment. The electronic device 100 has a folded state and a flattened state. Of course, in other embodiments, the electronic device 100 may also have one or more intermediate hovering states between the folded state and the flattened state. The electronic device 100 includes a flexible display screen 2 and a folding housing 1. The electronic device 100 provided in this application embodiment is an inward-folding electronic device, that is, the flexible display screen 2 is located inside the folding housing 1. The inward-folding electronic device 100 can effectively reduce the impact on the flexible display screen 2 and extend the service life of the flexible display screen 2. It should be noted that the main inventive concept provided in this application is also applicable to outward-folding electronic devices. When the electronic device 100 is in a flattened state, the flexible display screen 2 and the folding housing 1 are in a flattened state. At this time, the flexible display screen 2 is flattened under the action of the folding housing 1, which is beneficial for realizing a large-screen display. When the electronic device 100 is in the folded state, the flexible display screen 2 and the folding housing 1 are also in the folded state. At this time, the electronic device 100 is small in size and easy to carry. When the electronic device 100 is in the intermediate hovering state, the flexible display screen 2 and the folding housing 1 are also in the intermediate hovering state. In the following embodiments, for ease of description, the following is established... Figure 1 The coordinate system shown can be interpreted as follows: the X-axis can be understood as the length direction of the electronic device 100 and the folding shell 1; the Y-axis can be understood as the width direction of the electronic device 100 and the folding shell 1; and the Z-axis can be understood as the thickness direction of the electronic device 100 and the folding shell 1.

[0015] The folding housing 1 includes a first housing 11, a second housing 12, and a pivot mechanism 10. When the folding housing 1 is in a flattened state, the first housing 11 and the second housing 12 are respectively flattened on opposite sides of the pivot mechanism 10. At this time, the included angle between the first housing 11 and the second housing 12 can be 180° (a slight deviation is allowed, for example, the included angle between the first housing 11 and the second housing 12 can also be 175°, 177°, 179°, 182°, etc.). When the folding housing 1 is in a folded state, the first housing 11 and the second housing 12 are located on the same side of the pivot mechanism 10 and are arranged opposite each other. The first housing 11, the pivot mechanism 10, and the second housing 12 form a receiving space for accommodating the flexible display screen 2.

[0016] The flexible display screen 2 is used to display images. The flexible display screen 2 can be an organic light-emitting diode (OLED) display screen, a light-emitting diode (LED) display screen, etc. The flexible display screen 2 covers the first housing 11, the rotating shaft mechanism 10, and the second housing 12, with one end of the flexible display screen 2 fixedly connected to the first housing 11 and the other end fixedly connected to the second housing 12. Specifically, the flexible display screen 2 includes a first non-bending area 21, a bending area 20, and a second non-bending area 22 arranged sequentially. The first non-bending area 21 covers the first housing 11 and is fixedly connected to it; the second non-bending area 22 covers the second housing 12 and is fixedly connected to it. Understandably, the first non-bending area 21 flattens as the first housing 11 is flattened, and folds as the first housing 11 is folded; the second non-bending area 22 flattens as the second housing 12 is flattened, and folds as the second housing 12 is folded. The fixed connection between the first non-bending area 21 and the first housing 11 includes, but is not limited to, adhesive bonding; the fixed connection between the second non-bending area 22 and the second housing 12 includes, but is not limited to, adhesive bonding. The bending area 20 covers the pivot mechanism 10. The bending area 20 is not connected to or not fully connected to the pivot mechanism 10, allowing at least a portion of the bending area 20 to bend freely. The specific connection relationship between the bending area 20 of the flexible display screen 2 and the pivot mechanism 10 will be further explained in subsequent embodiments. When the flexible display screen 2 is in a flattened state, the first non-bending area 21, the bending area 20, and the second non-bending area 22 flatten under the action of the folding housing 1. When the flexible display screen 2 is in the folded state, the first non-bending area 21, the bending area 20 and the second non-bending area 22 are housed in the receiving space formed by the folded shell 1.

[0017] like Figure 2As shown, the flexible display screen 2 is approximately teardrop-shaped when folded. Specifically, the bending area 20 of the flexible display screen 2 includes a first sub-bending area 20, a second sub-bending area 20, and a third sub-bending area 20 arranged sequentially. It can be understood that the first non-bending area 21, the first sub-bending area 20, the second sub-bending area 20, the third sub-bending area 20, and the second non-bending area 22 are arranged sequentially. When the flexible display screen 2 is folded, the first sub-bending area 20 and the third sub-bending area 20 are positioned opposite each other. A first gap is formed between the end of the second sub-bending area 20 connecting to the first sub-bending area 20 and the end of the second sub-bending area 20 connecting to the third sub-bending area 20. A second gap is formed between the end of the first sub-bending area 20 connecting to the first non-bending area 21 and the end of the third sub-bending area 20 connecting to the second non-bending area 22. The size of the first gap is larger than the size of the second gap. The first gap can be referred to as dashed line segment a in the diagram, and the second gap can be referred to as dashed line segment b in the diagram. The second sub-bending area 20 is approximately arc-shaped. When the flexible display screen 2 is in the folded state, it is approximately teardrop-shaped, which can reduce the gaps in the electronic device 100 and improve the appearance of the electronic device 100.

[0018] Please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the folding shell 1 in a flattened state, as provided in the embodiments of this application. Figure 4This is an exploded view of the folding shell 1 provided in an embodiment of this application. In this embodiment, the first shell 11 and the second shell 12 of the folding shell 1 are structurally symmetrical. Of course, in other embodiments, the structures of the first shell 11 and the second shell 12 may be asymmetrical. Specifically, the first shell 11 includes a first base plate 110, a first support plate 112, and a first peripheral side plate 113. The first base plate 110, the first support plate 112, and the first peripheral side plate 113 may be integrally formed or connected to each other. The first base plate 110 and the first support plate 112 are disposed opposite to each other, and the first peripheral side plate 113 is connected between the first base plate 110 and the first support plate 112. The second shell 12 includes a second base plate 120, a second support plate 121, and a second peripheral side plate 122. The second base plate 120, the second support plate 121, and the second peripheral side plate 122 may be integrally formed or connected to each other. The second base plate 120 and the second support plate 121 are disposed opposite to each other, and the second peripheral side plate 122 is connected between the second base plate 120 and the second support plate 121. The first support plate 112, on the side facing away from the first substrate 110, is used to fix and connect the first non-bending area 21 of the flexible display screen 2; the second support plate 121, on the side facing away from the second substrate 120, is used to fix and connect the second non-bending area 22 of the flexible display screen 2. The size of the first substrate 110 and the first support plate 112 may be the same or different. The size of the second substrate 120 and the second support plate 121 may be the same or different. In this embodiment, the dimension of the first substrate 110 along the length X direction of the folded shell 1 is larger than the dimension of the first support plate 112 along the length X direction of the folded shell 1; the dimension of the second substrate 120 along the length X direction of the folded shell 1 is larger than the dimension of the second support plate 121 along the length X direction of the folded shell 1. In other words, the first substrate 110 includes a first body portion 1101 and a first extension portion 1102, the first body portion 1101 is disposed opposite to the first substrate 110, and the first extension portion 1102 extends toward the side where the second substrate 120 is located. The second substrate 120 includes a second body portion 1201 and a second extension portion 1202. The second body portion 1201 is disposed opposite to the second substrate 120, and the second extension portion 1202 extends toward the side where the first substrate 110 is located. When the folding shell 1 is in a flattened state, the end of the first extension portion 1102 away from the first body portion 1101 can contact the end of the second extension portion 1202 away from the second body portion 1201, so as to limit the folding shell 1 when flattened; the first extension portion 1102 and the second extension portion 1202 are used to support the rotating shaft mechanism 10.When the folded housing 1 is in the folded state, the first support plate 112 and the second support plate 121 are arranged opposite to each other and are used to support the first non-bending area 21 and the second non-bending area 22 of the flexible display screen 2, respectively; the first extension 1102 and the second extension 1202 are arranged opposite to each other and the first extension 1102, the second extension 1202 and the pivot mechanism 10 are used to accommodate the bending area 20 of the flexible display screen 2.

[0019] like Figure 5 As shown, the rotating shaft mechanism 10 includes a base 101, a first connecting seat 102, and a first rotating member 103. A first housing 11 is rotatably connected to the base 101, and the first housing 11 can rotate relative to the base 101 to achieve flattening and folding. Specifically, the first connecting seat 102 is located on one side of the base 101. Based on the accompanying drawings, one side of the base 101 can be understood as the left side of the base 101. In other embodiments, one side of the base 101 can also be the front or rear side of the base 101. The first housing 11 is fixedly connected to the first connecting seat 102. The first rotating member 103 is located between the base 101 and the first connecting seat 102. One end of the first rotating member 103 is rotatably connected to the base 101, and the other end of the first rotating member 103 is slidably connected to the first connecting seat 102. It can be understood that the first housing 11 achieves its rotatable connection with the base 101 through the first connecting seat 102 and the first rotating member 103. The fixed connection methods between the first housing 11 and the first connecting seat 102 include, but are not limited to, integral connection, threaded connection, snap-fit, welding, riveting, and bonding. The first rotating component 103 and the base 101 can be directly rotatably connected through the fit of a shaft and a hole or the fit of an arc-shaped groove and an arc-shaped sliding part, or they can be rotatably connected through other shaft components such as pins. The first rotating component 103 and the first connecting seat 102 can be slidably connected through the fit of a slide rail and a slider or the fit of a slide groove and a slider.

[0020] By fixing the first housing 11 to the first connecting seat 102, the fitting clearance between the first housing 11 and the first connecting seat 102 can be reduced, and the motion transition between the first housing 11 and the first connecting seat 102 can be avoided. This reduces the play in the first housing 11 and the first connecting seat 102, and improves the synchronicity of the rotation of the first housing 11 and the first connecting seat 102 relative to the base 101. By rotatably connecting one end of the first rotating member 103 to the base 101 and slidingly connecting the other end to the first connecting seat 102, while the first housing 11, the first connecting seat 102, and the first rotating member 103 rotate relative to the base 101, the first connecting seat 102 and the first rotating member 103 can only slide relative to each other and cannot rotate. Therefore, the rotational play between the first rotating member 103 and the first connecting seat 102 can be avoided, thereby improving the accuracy of the synchronous rotation of the first housing 11, the first connecting seat 102, and the first rotating member 103 relative to the base 101.

[0021] Please refer to Figure 6 and Figure 7 The first rotating member 103 and the first connecting seat 102 are movable relative to the base 101 to switch between a first state and a second state. In one embodiment, in the first state, the first rotating member 103 and the first connecting seat 102 are flattened relative to the base 101, and at this time, the first rotating member 103 and the first connecting seat 102 are parallel or approximately parallel to the base 101; in the second state, the first rotating member 103 and the first connecting seat 102 are folded relative to the base 101, and at this time, the first rotating member 103 and the first connecting seat 102 are perpendicular or approximately perpendicular to the base 101. It can be understood that in the first state, the first housing 11 is in a flattened state; in the second state, the first housing 11 is in a folded state. Of course, in other embodiments, at least one of the first state and the second state can correspond to the first housing 11 being in an intermediate suspended state; at this time, the first rotating member 103 and the first connecting seat 102 are tilted relative to the base 101. In the following embodiments, unless otherwise specified, the first state corresponds to the first housing 11 being in a flattened state, and the second state corresponds to the first housing 11 being in a folded state.

[0022] Further, please refer to Figure 8 and Figure 9The rotating shaft mechanism 10 also includes a first driving member 104 and a first supporting member 105. The first driving member 104 is located on one side of the base 101. In this embodiment, the first driving member 104 is located on the left side of the base 101. One end of the first driving member 104 is rotatably connected to one of the base 101 and the first connecting seat 102, and the other end of the first driving member 104 is rollably connected to the other of the base 101 and the first connecting seat 102. In other words, one end of the first driving member 104 is rotatably connected to the base 101, and the other end of the first driving member 104 is rollably connected to the first connecting seat 102; or, one end of the first driving member 104 is rotatably connected to the first connecting seat 102, and the other end of the first driving member 104 is rollably connected to the base 101. In the following embodiments, the example is that one end of the first driving member 104 is rotatably connected to the base 101, and the other end of the first driving member 104 is rollably connected to the first connecting seat 102. By rotatably connecting one end of the first driving member 104 to the base 101 and rollingly connecting the other end of the first driving member 104 to the first connecting seat 102, the structural design of the first connecting seat 102, the first driving member 104, and the first support member 105 can be facilitated, as well as the adjustment of the movement control of the first connecting seat 102 and the first driving member 104 on the first support member 105 can be made easier. The first driving member 104 and the base 101 can be directly rotatably connected through a shaft and hole fit or an arc-shaped groove and an arc-shaped sliding part fit, or they can be rotatably connected through other shaft components such as pins. The first driving member 104 and the first connecting seat 102 can be rollingly connected through a rolling groove and a rolling column fit.

[0023] Please refer to Figure 10 and Figure 11 When the first connecting seat 102 moves relative to the base 101, the first driving member 104 moves relative to the base 101. In one embodiment, when the first connecting seat 102 and the first rotating member 103 are in a first state, the first driving member 104 is flattened relative to the base 101; when the first connecting seat 102 and the first rotating member 103 are in a second state, the first driving member 104 is folded relative to the base 101. In this embodiment, by setting the first driving member 104, one end of the first driving member 104 is rotatably connected to one of the base 101 and the first connecting seat 102, and the other end of the first driving member 104 is rollwise connected to the other of the base 101 and the first connecting seat 102. The movement of the first support member 105 can be controlled by the cooperation of the first driving member 104 and the first connecting seat 102 to realize the support function of the first support member 105 and improve the accuracy of the movement trajectory of the first support member 105.

[0024] like Figure 9As shown, the first support member 105 is located on one side of the base 101. In this embodiment, the first support member 105 is located on the left side of the base 101. The first support member 105 is used to support the first sub-bending area 20 of the flexible display screen 2. In one embodiment, the first sub-bending area 20 is fixedly connected to the first support member 105. For example, the first sub-bending area 20 is bonded to the first support member 105. Of course, in other embodiments, the first sub-bending area 20 and the first support member 105 may not be fixedly connected. The first support member 105 is rotatably connected to the first connecting seat 102 and rollwise connected to the first driving member 104, or the first support member 105 is rollwise connected to the first connecting seat 102 and rotatably connected to the first driving member 104. In other words, one end of the first support member 105 is rotatably connected to the first connecting seat 102, and the other end of the first support member 105 is rollwise connected to the first driving member 104; or, one end of the first support member 105 is rotatably connected to the first driving member 104, and the other end of the first support member 105 is rollwise connected to the first connecting seat 102. In the following embodiments, one end of the first support member 105 is rotatably connected to the first connecting seat 102, and the other end of the first support member 105 is rollingly connected to the first driving member 104. The terms "one end" and "the other end" in this application are used only to indicate different parts of the components and should not be narrowly interpreted as the ends of the components. By rotatably connecting one end of the first support member 105 to the first connecting seat 102 and rollingly connecting the other end of the first support member 105 to the first driving member 104, the structural design of the first connecting seat 102, the first driving member 104, and the first support member 105 is facilitated, as is the adjustment of the motion control of the first connecting seat 102 and the first driving member 104 on the first support member 105. The first support member 105 and the first connecting seat 102 can be directly rotatably connected through the fit of a shaft and a hole or the fit of an arc-shaped groove and an arc-shaped sliding part, or they can be rotatably connected through other shaft components such as pins. The first support member 105 and the first driving member 104 can be rollingly connected through the fit of a rolling groove and a rolling column, etc.

[0025] Please refer to Figure 10 and Figure 11When the first connecting seat 102 and the first driving member 104 move relative to the base 101, the first supporting member 105 moves relative to the base 101. In one embodiment, when the first connecting seat 102 and the first driving member 104 are in a first state, the first supporting member 105 is flattened relative to the base 101; when the first connecting seat 102 and the first driving member 104 are in a second state, the end of the first supporting member 105 near the base 101 is inclined toward the side near the first connecting seat 102. The side of the first supporting member 105 facing the first sub-bending area 20 of the flexible display screen 2 is flat. In the first state, the first supporting member 105 is used to support the first sub-bending area 20 of the flexible display screen 2 to improve the stress on the first sub-bending area 20. In the second state, the end of the first support member 105 near the base 101 is tilted toward the side near the first connecting seat 102, which allows the first housing 11 to be close to the second housing 12, reducing the gap between the first housing 11 and the second housing 12, which is beneficial for supporting the flexible display screen 2 and realizing the teardrop-shaped folding of the flexible display screen 2.

[0026] In this configuration, one of the first housing 11, the first connecting seat 102, the first rotating member 103, the first driving member 104, and the first supporting member 105 can serve as the active member for flattening and folding the left side of the folding housing 1, while the others serve as driven members for flattening and folding the left side of the folding housing 1. When the first housing 11 serves as the active member, the rotation of the first housing 11 relative to the base 101 can be achieved by the external force applied by the user to the first housing 11, which in turn drives the first connecting seat 102 and the first rotating member 103 to rotate relative to the base 101, thereby achieving flattening and folding. Since one end of the first driving member 104 is connected to the base 101 and the other end is connected to the first connecting seat 102, when the first connecting seat 102 rotates relative to the base 101, it can also drive the first driving member 104 to move relative to the base 101. The first support member 105 is connected to the first connecting seat 102 and the first driving member 104. Therefore, when the first connecting seat 102 and the first driving member 104 rotate relative to the base 101, they can also drive the first support member 105 to move relative to the base 101, so as to realize the flattening and tilting of the first support member 105. When one of the first connecting seat 102, the first rotating member 103, the first driving member 104, and the first supporting member 105 acts as the active member, a corresponding driving structure (e.g., a motor) can be provided inside the folding housing 1. Through the action of the driving structure, one of the first connecting seat 102, the first rotating member 103, the first driving member 104, and the first supporting member 105 rotates relative to the base 101, thereby driving the others, including the first housing 11, to rotate relative to the base 101, thus achieving automatic flattening and folding of the left side of the folding housing 1. In this embodiment, to simplify the structure of the folding housing 1, the first housing 11 is used as the active member for flattening and folding on the left side of the folding housing 1 as an example.

[0027] The rotating shaft mechanism 10 provided in the above embodiment includes a base 101, a first connecting seat 102, a first rotating member 103, a first driving member 104, and a first supporting member 105. Since the first connecting seat 102 is located on one side of the base 101, and the first rotating member 103 is located between the first connecting seat 102 and the base 101, one end of the first rotating member 103 is rotatably connected to the base 101, and the other end is slidably connected to the first connecting seat 102, so that the first connecting seat 102 and the first rotating member 103 can only slide relative to each other and cannot rotate. This is beneficial for controlling the movement of the first connecting seat 102 and the first rotating member 103 relative to the base 101 and improving the movement accuracy of the first connecting seat 102 and the first rotating member 103 when switching between the first state and the second state. Since one end of the first driving member 104 is rotatably connected to one of the base 101 and the first connecting seat 102, and the other end of the first driving member 104 is rotatably connected to the other of the base 101 and the first connecting seat 102, and one end of the first support member 105 is rotatably connected to one of the first connecting seat 102 and the first driving member 104, and the other end is rotatably connected to the other of the first connecting seat 102 and the first driving member 104, the first support member 105 can move relative to the base 101 under the drive of the first connecting seat 102 and the first driving member 104. This facilitates the support function of the first support member 105 in the first state and the second state, so that when it is applied to the folding shell 1 and the electronic device 100, it can reduce the folding gap of the folding shell 1 and the electronic device 100, improve the appearance, and support the flexible display screen 2 of the electronic device 100. Furthermore, the first driving member 104 is rolledly connected to one of the base 101 and the first connecting seat 102, meaning that the first driving member 104 can slide and rotate relative to one of the base 101 and the first connecting seat 102. The first support member 105 is rolledly connected to one of the first connecting seat 102 and the first driving member 104, meaning that the first support member 105 can slide and rotate relative to one of the first connecting seat 102 and the first rotating member 103. This facilitates the realization of multiple motion trajectories of the first support member 105, enabling it to meet design requirements and further improving the motion accuracy of the first support member 105.

[0028] like Figure 12As shown, the second housing 12 is rotatably connected to the base 101. The manner in which the second housing 12 is rotatably connected to the base 101 can be the same as or different from the manner in which the first housing 11 is rotatably connected to the base 101 in the above embodiments. In this embodiment, the manner in which the second housing 12 is rotatably connected to the base 101 is substantially the same as the manner in which the first housing 11 is rotatably connected to the base 101 in the above embodiments. Of course, in other embodiments, the second housing 12 and the base 101 can be directly rotatably connected through the fit of a shaft and a hole or the fit of an arc-shaped groove and an arc-shaped sliding part, or they can be rotatably connected through other shaft components such as pins. The second housing 12 and the first housing 11 rotate relative to the base 101 to achieve the flattening and folding of the folding housing 1. Specifically, the rotating shaft mechanism 10 also includes a second connecting seat 106 and a third rotating member 107. The second connecting seat 106 is located on the other side of the base 101. The other side of the base 101 is opposite to one side of the base 101. In other words, based on the accompanying drawings of this application, the other side of the base 101 can be understood as the right side of the base 101. In other embodiments, the other side of the base 101 can also be the front or rear side of the base 101. The second housing 12 is fixedly connected to the second connecting seat 106. The third rotating member 107 is located between the base 101 and the second connecting seat 106. One end of the third rotating member 107 is rotatably connected to the base 101, and the other end of the third rotating member 107 is slidably connected to the first connecting seat 102. It can be understood that the second housing 12 achieves its rotatable connection with the base 101 through the second connecting seat 106 and the third rotating member 107. The fixed connection methods between the second housing 12 and the second connecting seat 106 include, but are not limited to, integral connection, threaded connection, snap-fit, welding, riveting, and bonding. The third rotating member 107 and the base 101 can be directly rotatably connected through the fit of a shaft and a hole or the fit of an arc track groove and an arc sliding part, or they can be rotatably connected through other shaft components such as a pin. The third rotating member 107 and the second connecting seat 106 can be slidably connected through the fit of a slide rail and a slider or the fit of a slide groove and a slider.

[0029] By fixing the second housing 12 to the second connecting seat 106, the fitting clearance between the second housing 12 and the second connecting seat 106 can be reduced, and the motion transition between the second housing 12 and the second connecting seat 106 can be avoided. This reduces the play in the second housing 12 and the second connecting seat 106, and improves the synchronicity of the rotation of the second housing 12 and the second connecting seat 106 relative to the base 101. By rotatably connecting one end of the third rotating member 107 to the base 101 and slidingly connecting the other end to the second connecting seat 106, while the second housing 12, the second connecting seat 106, and the third rotating member 107 rotate relative to the base 101, the second connecting seat 106 and the third rotating member 107 can only slide relative to each other and cannot rotate. Therefore, the rotational play between the third rotating member 107 and the second connecting seat 106 can be avoided, thereby improving the accuracy of the synchronous rotation of the second housing 12, the second connecting seat 106, and the third rotating member 107 relative to the base 101.

[0030] Of course, in other embodiments, the second housing 12 may be fixedly connected to the base 101. In this case, only the first housing 11 in the folding housing 1 can rotate relative to the base 101 to achieve flattening and folding. The second housing 12 remains stationary with respect to the base 101. The fixed connection methods between the second housing 12 and the base 101 include, but are not limited to, integral connection, threaded connection, snap-fit, welding, riveting, and bonding.

[0031] Please refer to Figure 13 and Figure 14The third rotating member 107 and the second connecting seat 106 are movable relative to the base 101 to switch between a third state and a fourth state. In one embodiment, in the third state, the third rotating member 107 and the second connecting seat 106 are flattened relative to the base 101, and at this time, the third rotating member 107 and the second connecting seat 106 are parallel or approximately parallel to the base 101; in the fourth state, the third rotating member 107 and the second connecting seat 106 are folded relative to the base 101, and at this time, the third rotating member 107 and the second connecting seat 106 are perpendicular or approximately perpendicular to the base 101. It can be understood that in the third state, the second housing 12 is in a flattened state; in the fourth state, the second housing 12 is in a folded state. Of course, in other embodiments, at least one of the third state and the fourth state can correspond to the second housing 12 being in an intermediate suspended state; at this time, the third rotating member 107 and the second connecting seat 106 are tilted relative to the base 101. In the following embodiments, unless otherwise specified, the third state corresponds to the second housing 12 being in a flattened state, and the fourth state corresponds to the second housing 12 being in a folded state. It can be understood that when the first housing 11 is in the first state and the second housing 12 is in the third state, the corresponding rotating shaft mechanism 10 is in a flattened state; when the first housing 11 is in the second state and the second housing 12 is in the fourth state, the corresponding rotating shaft mechanism 10 is in a folded state.

[0032] Please refer to Figure 15 and Figure 16The rotating shaft mechanism 10 also includes a second driving member 108 and a second support member 109. The second driving member 108 is located on the other side of the base 101. In this embodiment, the second driving member 108 is located on the right side of the base 101. One end of the second driving member 108 is rotatably connected to one of the base 101 and the second connecting seat 106, and the other end of the second driving member 108 is rollably connected to the other of the base 101 and the second connecting seat 106. In other words, one end of the second driving member 108 is rotatably connected to the base 101, and the other end of the second driving member 108 is rollably connected to the second connecting seat 106; or, one end of the second driving member 108 is rotatably connected to the second connecting seat 106, and the other end of the second driving member 108 is rollably connected to the base 101. In the following embodiments, the example is that one end of the second driving member 108 is rotatably connected to the base 101, and the other end of the second driving member 108 is rollably connected to the second connecting seat 106. By rotatably connecting one end of the second driving member 108 to the base 101 and rollingly connecting the other end of the second driving member 108 to the second connecting seat 106, the structural design of the second connecting seat 106, the second driving member 108, and the second support member 109 can be facilitated, as well as the adjustment of the movement control of the second connecting seat 106 and the second driving member 108 on the second support member 109 can be made easier. The second driving member 108 and the base 101 can be directly rotatably connected through a shaft and hole fit or a circular arc track groove and a circular arc sliding part fit, or they can be rotatably connected through other shaft components such as pins. The second driving member 108 and the second connecting seat 106 can be rollingly connected through a rolling groove and a rolling column fit.

[0033] Please refer to Figure 17 and Figure 18 When the second connecting seat 106 moves relative to the base 101, the second driving member 108 moves relative to the base 101. In one embodiment, when the second connecting seat 106 and the third rotating member 107 are in the third state, the second driving member 108 is flattened relative to the base 101; when the second connecting seat 106 and the third rotating member 107 are in the fourth state, the second driving member 108 is folded relative to the base 101. In this embodiment, by setting the second driving member 108, one end of the second driving member 108 is rotatably connected to one of the base 101 and the second connecting seat 106, and the other end of the second driving member 108 is rollwise connected to the other of the base 101 and the second connecting seat 106. The movement of the second connecting seat 106 can be controlled by the cooperation of the second driving member 108 and the second connecting seat 106 to realize the supporting function of the second support member 109 and improve the accuracy of the movement trajectory of the second support member 109.

[0034] like Figure 16As shown, the rotating shaft mechanism 10 also includes a second support member 109. The second support member 109 is located on the other side of the base 101. In this embodiment, the second support member 109 is located on the right side of the base 101. The second support member 109 is used to support the third sub-bending area 20 of the flexible display screen 2. In one embodiment, the third sub-bending area 20 is fixedly connected to the second support member 109. For example, the third sub-bending area 20 is bonded to the second support member 109. Of course, in other embodiments, the third sub-bending area 20 and the second support member 109 may not be fixedly connected. The second support member 109 is rotatably connected to the second connecting seat 106 and rollwise connected to the second driving member 108, or the second support member 109 is rollwise connected to the second connecting seat 106 and rotatably connected to the second driving member 108. In other words, one end of the second support member 109 is rotatably connected to the second connecting seat 106, and the other end of the second support member 109 is rollably connected to the second driving member 108; or, one end of the second support member 109 is rotatably connected to the second driving member 108, and the other end of the second support member 109 is rollably connected to the second connecting seat 106. The following embodiment uses the example of one end of the second support member 109 being rotatably connected to the second connecting seat 106 and the other end being rollably connected to the second driving member 108. By rotatably connecting one end of the second support member 109 to the second connecting seat 106 and rollably connecting the other end of the second support member 109 to the second driving member 108, the structural design of the second connecting seat 106, the second driving member 108, and the second support member 109 is facilitated, as is the adjustment of the movement control of the second support member 109 by the second connecting seat 106 and the second driving member 108. The second support member 109 and the second connecting seat 106 can be directly rotatably connected through the fit of a shaft and a hole or the fit of an arc-shaped groove and an arc-shaped sliding part, or they can be rotatably connected through other shaft components such as pins. The second support member 109 and the second driving member 108 can be rolled together through the fit of a rolling groove and a roller.

[0035] Please refer to Figure 17 and Figure 18When the second connecting seat 106 and the second driving member 108 move relative to the base 101, the second supporting member 109 moves relative to the base 101. In one embodiment, when the second connecting seat 106 and the second driving member 108 are in a third state, the second supporting member 109 is flattened relative to the base 101; when the second connecting seat 106 and the second driving member 108 are in a fourth state, the end of the second supporting member 109 near the base 101 is inclined toward the side near the second connecting seat 106. The side of the second supporting member 109 facing the third sub-bending area 20 of the flexible display screen 2 is flat. In the third state, the second supporting member 109 is used to support the third sub-bending area 20 of the flexible display screen 2 to improve the stress on the third sub-bending area 20. In the fourth state, the end of the second support member 109 near the base 101 is tilted toward the side near the second connecting seat 106, which allows the second housing 12 to be close to the first housing 11, reducing the gap between the second housing 12 and the first housing 11. At this time, the accommodating space formed by the first housing 11, the second housing 12 and the rotating shaft mechanism 10 is conducive to making the flexible display screen 2 approximately teardrop-shaped.

[0036] Among them, one of the second housing 12, the second connecting seat 106, the third rotating member 107, the second driving member 108, and the second supporting member 109 can serve as the active member for flattening and folding the right side of the folding housing 1, while the others serve as the driven members for flattening and folding the right side of the folding housing 1. When the second housing 12 serves as the active member, the rotation of the second housing 12 relative to the base 101 can be achieved by the external force applied by the user to the second housing 12, which in turn drives the second connecting seat 106 and the third rotating member 107 to rotate relative to the base 101, thereby achieving flattening and folding. Since one end of the second driving member 108 is connected to the base 101 and the other end is connected to the second connecting seat 106, when the second connecting seat 106 rotates relative to the base 101, it can also drive the second driving member 108 to move relative to the base 101. The second support member 109 is connected to the second connecting seat 106 and the second driving member 108. Therefore, when the second connecting seat 106 and the second driving member 108 rotate relative to the base 101, they can also drive the second support member 109 to move relative to the base 101, so as to realize the flattening and tilting of the second support member 109. When one of the second connecting seat 106, the third rotating member 107, the second driving member 108, and the second supporting member 109 acts as the active member, a corresponding driving structure (e.g., a motor) can be provided inside the folding housing 1. The driving structure enables one of the two members (the second connecting seat 106, the third rotating member 107, the second driving member 108, and the second supporting member 109) to rotate relative to the base 101, thereby driving the others, including the second housing 12, to rotate relative to the base 101, thus achieving automatic flattening and folding of the right side of the folding housing 1. In this embodiment, to simplify the structure of the folding housing 1, the second housing 12 is used as the active member for flattening and folding the right side of the folding housing 1. In this embodiment, the rotation of the first housing 11 relative to the base 101 is independent of the rotation of the second housing 12 relative to the base 101. Of course, in other embodiments, when the first housing 11 and the second housing 12 need to rotate synchronously, a corresponding synchronization mechanism can be provided inside the folding housing 1. In other words, in the embodiments of this application, the state of the first housing 11 and the state of the second housing 12 can be the same or different; for example, when the first housing 11 is in a flattened state, the second housing 12 can be in a flattened state, a folded state, or a hovering state.

[0037] The rotating shaft mechanism 10 provided in this embodiment also includes a base 101, a second connecting seat 106, a third rotating member 107, a second driving member 108, and a second supporting member 109. Since the second connecting seat 106 is located on the other side of the base 101, and the third rotating member 107 is located between the second connecting seat 106 and the base 101, one end of the third rotating member 107 is rotatably connected to the base 101, and the other end is slidably connected to the second connecting seat 106, so that the second connecting seat 106 and the third rotating member 107 can only slide relative to each other and cannot rotate. This is beneficial for controlling the movement of the second connecting seat 106 and the third rotating member 107 relative to the base 101 and improving the movement accuracy of the second connecting seat 106 and the third rotating member 107 when switching between the third state and the fourth state. Since one end of the second driving member 108 is rotatably connected to one of the base 101 and the second connecting seat 106, and the other end of the second driving member 108 is rotatably connected to the other of the base 101 and the second connecting seat 106, and one end of the second support member 109 is rotatably connected to one of the second connecting seat 106 and the second driving member 108, and the other end is rotatably connected to the other of the second connecting seat 106 and the second driving member 108, the second support member 109 can move relative to the base 101 under the drive of the second connecting seat 106 and the second driving member 108. This facilitates the support function of the second support member 109 in the third and fourth states, so that when applied to the folding shell 1 and the electronic device 100, it can reduce the folding gap of the folding shell 1 and the electronic device 100, improve the appearance, and support the flexible display screen 2 of the electronic device 100. Furthermore, the second driving member 108 is rolled to one of the base 101 and the second connecting seat 106, meaning that the second driving member 108 can slide and rotate relative to one of the base 101 and the second connecting seat 106. The second support member 109 is rolled to one of the second connecting seat 106 and the third rotating member 107, meaning that the second support member 109 can slide and rotate relative to one of the second connecting seat 106 and the third rotating member 107. This facilitates the realization of multiple motion trajectories of the second support member 109, enabling it to meet design requirements and further improving the motion accuracy of the second support member 109.

[0038] Furthermore, when the rotating shaft mechanism 10 is in the folded state, the first support member 105, driven by the first connecting seat 102 and the first driving member 104, can tilt its end near the base 101 toward the side near the first connecting seat 102; the second support member 109, driven by the second connecting seat 106 and the second driving member 108, can tilt its end near the base 101 toward the side near the second connecting seat 106. That is, the distance between the end of the first support member 105 away from the base 101 and the end of the second support member 109 away from the base 101 is less than the distance between the end of the first support member 105 near the base 101 and the end of the second support member 109 near the base 101. In other words, when the pivot mechanism 10 is in the folded state, the first support member 105 and the second support member 109 form a accommodating space that is narrower at the end away from the base 101 and wider at the end closer to the base 101. When applied to the folding housing 1, this facilitates the first housing 11 and the second housing 12 to approach each other, achieving seamless folding of the folding housing 1. The first support member 105 is fixedly connected to the first sub-bending area 20 of the flexible display screen 2, and the second support member 109 is fixedly connected to the third sub-bending area 20 of the flexible display screen 2. When the pivot mechanism 10 is in the folded state, the first housing 11 and the second housing 12 are positioned opposite each other, that is, the first non-bending area 21 and the second non-bending area 22 of the flexible display screen 2 are positioned opposite each other. The base 101 and the second sub-bending area 20 of the flexible display screen 2 are not connected, and the second sub-bending area 20 is freely bent. This allows the flexible display screen 2 of the electronic device 100 to be approximately teardrop-shaped when folded.

[0039] The second connecting seat 106 and the first connecting seat 102 can be symmetrically arranged about the central axis of the rotating shaft mechanism 10, or they can be staggered. The third rotating member 107 and the first rotating member 103 can be symmetrically arranged about the central axis of the rotating shaft mechanism 10, or they can be staggered. The second driving member 108 and the first driving member 104 can be symmetrically arranged about the central axis of the rotating shaft mechanism 10, or they can be staggered. The second support member 109 and the first support member 105 can be symmetrically arranged about the central axis of the rotating shaft mechanism 10, or they can be staggered. The central axis of the rotating shaft mechanism 10 can be referred to as axis M in the attached drawings. In this application, the direction of the central axis M of the rotating shaft mechanism 10 can also be understood as the width direction of the folding housing 1 and the electronic device 100. In this embodiment, the second connecting seat 106 and the first connecting seat 102 are symmetrically arranged about the central axis M of the rotating shaft mechanism 10; the third rotating member 107 and the first rotating member 103 are symmetrically arranged about the central axis M of the rotating shaft mechanism 10; the second driving member 108 and the first driving member 104 are symmetrically arranged about the central axis M of the rotating shaft mechanism 10; and the second support member 109 and the first support member 105 are symmetrically arranged about the central axis M of the rotating shaft mechanism 10.

In this embodiment, the first slider 1031 and the first groove 102a are both rectangular, so that the first rotating member 103 slides linearly relative to the first connecting seat 102.

[0044] like Figure 20As shown, the second connecting seat 106 includes a fourth rotating part 1060, a second sliding part 1061, and a fifth rolling part 1062 arranged sequentially.

Of course, in other embodiments, the second slider 1071 may be disposed on the second connecting seat 106, and the second sliding groove 106a may be disposed on the third rotating member 107. In this embodiment, the second slider 1071 and the second slide groove 106a are both rectangular, so that the third rotating member 107 slides linearly relative to the second connecting seat 106.

[0046] Please refer to Figure 22 and Figure 23The first driving member 104 and the first rotating member 103 are arranged along the central axis M of the rotating shaft mechanism 10. The first driving member 104 includes a first main body 1040, a second rotating part 1041, a second rolling part 1042, and a third rolling part 1043. The first main body 1040 is connected to the second rotating part 1041. For example, the first main body 1040 and the second rotating part 1041 are integrally formed, or the first main body 1040 and the second rotating part 1041 are fixedly connected by a connector. The second rolling part 1042 and the third rolling part 1043 are both located at the end of the first main body 1040 away from the second rotating part 1041. The second rolling part 1042 and the third rolling part 1043 are disposed opposite to each other on both sides of the first main body 1040.

The third rolling part 1043 is rollingly connected to the first support member 105.

[0047] Optionally, the first driving member 104 and the base 101 are rotatably connected via a second rotating shaft 1012 and a second shaft hole 104a. The second rotating part 1041 and the base 101 are also rotatably connected via a second rotating shaft 1012 and a second shaft hole 104a. In this embodiment, the second rotating shaft 1012 is a fixed shaft. Of course, in other embodiments, the second rotating shaft 1012 can also be a movable shaft. The second rotating shaft 1012 is parallel to the central axis M of the rotating shaft mechanism 10. Optionally, the first driving member 104 has a second shaft hole 104a. The second rotating shaft 1012 passes through the second shaft hole 104a, and both ends of the second rotating shaft 1012 are respectively fixed to the base 101. The second rotating shaft 1012 forms a rotating pair between the first driving member 104 and the base 101, which facilitates the assembly of the first driving member 104 and the base 101 and facilitates the mass production of the rotating shaft mechanism 10. Of course, in other embodiments, the second rotating shaft 1012 may also be integrally formed with one of the base 101 and the first driving member 104.

[0048] Optionally, one of the second rolling portion 1042 and the first rolling portion 1022 includes a first rolling groove 102b, and the other of the second rolling portion 1042 and the first rolling portion 1022 includes a first rolling column 104b. The first rolling groove 102b and the first rolling column 104b cooperate to enable the second rolling portion 1042 and the first rolling portion 1022 to be in a rolling connection. In one embodiment, the first rolling portion 1022 has a first rolling groove 102b, and the second rolling portion 1042 includes a first rolling column 104b, with the first rolling groove 102b cooperating with the first rolling column 104b. In other words, the first rolling column 104b is disposed on the first driving member 104, the first rolling groove 102b is disposed on the first connecting seat 102, and the first rolling column 104b rolls within the first rolling groove 102b. In this embodiment, the rolling connection between the first driving member 104 and the first connecting seat 102 is achieved through the cooperation of the first rolling groove 102b and the first rolling column 104b. This facilitates the first driving member 104 to move relative to the first connecting seat 102 along a preset trajectory by designing the shape and size of the first rolling groove 102b and the first rolling column 104b. This allows for better control of the movement and power transmitted from the first driving member 104 to the first support member 105, thereby improving the accuracy of the first driving member 104 in driving the first support member 105.

[0049] Please refer to Figure 23 and Figure 24 The first rolling groove 102b includes a first limiting wall 102c, a first trajectory wall 102d, a second limiting wall 102e, and a second trajectory wall 102f connected in sequence.

The first limiting wall 102c, the first trajectory wall 102d, the second limiting wall 102e, and the second trajectory wall 102f are all curved. The first rolling column 104b is cylindrical. In the first state, the first rolling column 104b abuts against the first limiting wall 102c. When the first connecting seat 102 is in the first state, the first rolling column 104b abuts against the first limiting arm, which can restrict the rolling of the first driving member 104 relative to the first connecting seat 102, preventing the first driving member 104 from affecting the first support member 105 in maintaining the first state. In the second state, the first rolling column 104b abuts against the second limiting wall 102e. When the first connecting seat 102 is in the second state, the first rolling column 104b abuts against the second limiting arm to restrict the rolling of the first driving member 104 relative to the first connecting seat 102, preventing the first driving member 104 from driving the first support member 105 to move and pull the flexible display screen 2 in the second state. When the first support member 105 switches between the first state and the second state, the first rolling column 104b rolls between the first track wall 102d and the second track wall 102f.

[0050] Please refer to Figure 22 and Figure 23 The second driving member 108 and the third rotating member 107 are arranged along the central axis M of the rotating shaft mechanism 10. The second driving member 108 includes a third main body 1080, a fifth rotating part 1081, a sixth rolling part 1082, and a seventh rolling part 1083. The third main body 1080 is connected to the fifth rotating part 1081. For example, the third main body 1080 and the fifth rotating part 1081 are integrally formed, or the third main body 1080 and the fifth rotating part 1081 are fixedly connected by a connector. The sixth rolling part 1082 and the seventh rolling part 1083 are both located at the end of the third main body 1080 away from the fifth rotating part 1081. The sixth rolling part 1082 and the seventh rolling part 1083 are disposed opposite to each other on both sides of the third main body 1080. The fifth rotating part 1081 is rotatably connected to the base 101. The sixth rolling part 1082 is rollingly connected to the fifth rolling part 1082. The sixth rolling part 1082 is rolled to connect with the second support member 109.

[0051] Optionally, the second driving member 108 and the base 101 are rotatably connected via a fourth rotating shaft 1014 and a fourth shaft hole 108a. The fifth rotating part 1081 and the base 101 are also rotatably connected via a fourth rotating shaft 1014 and a fourth shaft hole 108a. In this embodiment, the fourth rotating shaft 1014 is a fixed shaft. Of course, in other embodiments, the fourth rotating shaft 1014 can also be a movable shaft. The fourth rotating shaft 1014 is parallel to the central axis M of the rotating shaft mechanism 10. Optionally, the second driving member 108 has a fourth shaft hole 108a. The fourth rotating shaft 1014 passes through the fourth shaft hole 108a, and both ends of the fourth rotating shaft 1014 are respectively fixed to the base 101. The fourth rotating shaft 1014 forms a rotating pair between the second driving member 108 and the base 101, which facilitates the assembly of the second driving member 108 and the base 101 and facilitates the mass production of the rotating shaft mechanism 10. Of course, in other embodiments, the fourth rotating shaft 1014 may also be integrally formed with one of the base 101 and the second driving member 108.

[0052] Optionally, one of the sixth rolling portion 1082 and the fifth rolling portion 1062 includes a third rolling groove 106b, and the other of the sixth rolling portion 1082 and the fifth rolling portion 1062 includes a third rolling column 108b. The third rolling groove 106b and the third rolling column 108b cooperate to enable the sixth rolling portion 1082 and the fifth rolling portion 1062 to be rolled in a rolling connection. In one embodiment, the fifth rolling portion 1062 has a third rolling groove 106b, and the sixth rolling portion 1082 includes a third rolling column 108b, with the third rolling groove 106b cooperating with the third rolling column 108b. In other words, the third rolling column 108b is disposed on the second driving member 108, the third rolling groove 106b is disposed on the second connecting seat 106, and the third rolling column 108b rolls within the third rolling groove 106b. In this embodiment, the rolling connection between the second driving member 108 and the first connecting seat 102 is achieved through the cooperation of the third rolling groove 106b and the third rolling column 108b. This facilitates the second driving member 108 to move relative to the second connecting seat 106 along a preset trajectory by designing the shape and size of the third rolling groove 106b and the third rolling column 108b. This allows for better control of the movement and power transmitted from the second driving member 108 to the second supporting member 109, thereby improving the accuracy of the second driving member 108 in driving the second supporting member 109.

[0053] Please refer to Figure 23 and Figure 24 The third rolling groove 106b includes a fifth limiting wall 106c, a fifth trajectory wall 106d, a sixth limiting wall 106e, and a sixth trajectory wall 106f connected in sequence. The fifth limiting wall 106c is located on the side of the sixth limiting wall 106e away from the base 101. The fifth limiting wall 106c, the fifth trajectory wall 106d, the sixth limiting wall 106e, and the sixth trajectory wall 106f are all curved. The third rolling column 108b is cylindrical. In the third state, the third rolling column 108b abuts against the fifth limiting wall 106c. When the second connecting seat 106 is in the third state, the third rolling column 108b abutting against the fifth limiting wall 106c can restrict the rolling of the second driving member 108 relative to the first connecting seat 102, preventing the second driving member 108 from affecting the second support member 109 in maintaining the third state. In the fourth state, the third rolling column 108b abuts against the sixth limiting wall 106e. When the second connecting seat 106 is in the fourth state, the third rolling column 108b abuts against the sixth limiting wall 106e, which can limit the rolling of the second driving member 108 relative to the second connecting seat 106, preventing the second driving member 108 from driving the second support member 109 to move and pull the flexible display screen 2 in the fourth state. When the second support member 109 switches between the third and fourth states, the third rolling column 108b rolls between the fifth track wall 106d and the sixth track wall 106f.

[0054] Optional, please refer to Figure 25 and Figure 26 The first support member 105 includes a second main body portion 1050, a third rotating portion 1051, and a fourth rolling portion 1052. At least a portion of the second main body portion 1050 covers the first connecting seat 102. In other words, at least a portion of the second main body portion 1050 is located on the side of the first connecting seat 102 facing the first sub-bending area 20 of the flexible display screen 2. For example, a portion of the second main body portion 1050 covers the first connecting seat 102, and another portion of the second main body portion 1050 covers one side of the base 101; or, the second main body portion 1050 completely covers the first connecting seat 102; or, a portion of the second main body portion 1050 covers the first connecting seat 102, and another portion of the second main body portion 1050 extends toward the side of the first connecting seat 102 away from the base 101 (the side where the first housing 11 is located). In the following embodiments, the second main body portion 1050 completely covers the first connecting seat 102 as an example. By covering the first connecting seat 102 with the second main body 1050, the size of the rotating shaft mechanism 10 along the X-axis can be reduced, thereby facilitating the miniaturization of the rotating shaft mechanism 10. The third rotating part 1051 and the fourth rolling part 1052 are both provided on the side of the second main body 1050 facing the first connecting seat 102. The third rotating part 1051 is rotatably connected to the first rotating part 1020 of the first connecting seat 102. The fourth rolling part 1052 is rollably connected to the third rolling part 1043 of the first driving member 104.

[0055] By placing both the third rotating part 1051 and the fourth rolling part 1052 on the side of the second main body 1050 facing the first connecting seat 102, it is beneficial to achieve a rotatable connection between the third rotating part 1051 and the first connecting seat 102, and a rolling connection between the fourth rolling part 1052 and the first driving member 104. Furthermore, placing both the third rotating part 1051 and the fourth rolling part 1052 on the side of the main body facing the first connecting seat 102 can reduce the distance between the first support member 105 and the first connecting seat 102, improving the structural compactness of the rotating shaft mechanism 10 and facilitating its miniaturization and weight reduction.

[0056] Please refer to Figure 25 and Figure 26The second support member 109 includes a fourth main body portion 1090, a sixth rotating portion 1091, and an eighth rolling portion 1092. At least a portion of the fourth main body portion 1090 covers the second connecting seat 106. In other words, at least a portion of the fourth main body portion 1090 is located on the side of the second connecting seat 106 facing the third sub-bending area 20 of the flexible display screen 2. For example, a portion of the fourth main body portion 1090 covers the second connecting seat 106, and another portion of the fourth main body portion 1090 covers the other side of the base 101; or, the fourth main body portion 1090 completely covers the second connecting seat 106; or, a portion of the fourth main body portion 1090 covers the second connecting seat 106, and another portion of the fourth main body portion 1090 extends toward the side of the second connecting seat 106 away from the base 101 (the side where the second housing 12 is located). In the following embodiments, the fourth main body portion 1090 completely covers the second connecting seat 106 as an example. By covering the second connecting seat 106 with the fourth main body 1090, the size of the rotating shaft mechanism 10 along the X-axis direction can be reduced, thereby facilitating the miniaturization of the rotating shaft mechanism 10. The sixth rotating part 1091 and the eighth rolling part 1092 are both provided on the side of the fourth main body 1090 facing the second connecting seat 106. The sixth rotating part 1091 is rotatably connected to the fourth rotating part 1060 of the second connecting seat 106. The eighth rolling part 1092 is rollably connected to the seventh rolling part 1083 of the second driving member 108.

[0057] By placing both the sixth rotating part 1091 and the eighth rolling part 1092 on the side of the fourth main body 1090 facing the second connecting seat 106, it is beneficial to achieve a rotatable connection between the sixth rotating part 1091 and the second connecting seat 106, and a rolling connection between the eighth rolling part 1092 and the second driving member 108. Furthermore, placing both the sixth rotating part 1091 and the eighth rolling part 1092 on the side of the main body facing the second connecting seat 106 can also reduce the distance between the second support member 109 and the second connecting seat 106, improving the structural compactness of the rotating shaft mechanism 10 and facilitating its miniaturization and weight reduction.

[0058] Optional, please refer to Figures 26 to 28One of the third rotating part 1051 and the first rotating part 1020 includes a first arcuate groove 105a, and the other of the third rotating part 1051 and the first rotating part 1020 includes a first arcuate block 1023. The first arcuate groove 105a and the first arcuate block 1023 cooperate to rotatably connect the third rotating part 1051 and the first rotating part 1020. In one embodiment, the third rotating part 1051 has a first arcuate groove 105a. The first rotating part 1020 includes a first arcuate block 1023, and the first arcuate groove 105a cooperates with the first arcuate block 1023. In other words, the first arcuate groove 105a is provided on the first support member 105, and the first arcuate block 1023 is provided on the first connecting seat 102. The first arcuate block 1023 rotates in contact with the first arcuate groove 105a. Of course, in other embodiments, the first arc groove 105a can be disposed on the first connecting seat 102, and the first arc block 1023 can be disposed on the first support member 105. The rotational connection between the first support member 105 and the first connecting seat 102 achieved through the cooperation of the first arc groove 105a and the first arc block 1023 allows the first support member 105 to rotate relative to the first connecting seat 102 along the central axis of the first arc groove 105a. Since the central axis of the first arc groove 105a can be close to or located on the flexible display screen 2, the rotational design of the first support member 105 relative to the first connecting seat 102 is more flexible, facilitating the adjustment of the movement trajectory of the first support member 105 and realizing the flattening and teardrop folding of the flexible display screen 2.

[0059] The first arcuate groove 105a of the first support member 105 includes a first arcuate surface 1051a and a first limiting surface 1051b adjacent to the first arcuate surface 1051a. The first arcuate block 1023 of the first connecting seat 102 includes a second arcuate surface 1023a and a second limiting surface 1023b adjacent to the second arcuate surface 1023a. The first arcuate surface 1051a and the second arcuate surface 1023a are at least partially in contact. The first limiting surface 1051b and the second limiting surface 1023b are disposed opposite to each other. When the first connecting seat 102 is in the second state, the first limiting surface 1051b and the second limiting surface 1023b abut against each other. The abutment of the first limiting surface 1051b and the second limiting surface 1023b when the first connecting seat 102 is in the second state can limit the tilt angle of the first support member 105 relative to the base 101, and prevent the tilt angle of the first support member 105 from being too large, thus avoiding pulling on the flexible display screen 2.

[0060] Optional, please refer to Figures 26 to 28One of the sixth rotating part 1091 and the fourth rotating part 1060 includes a second arcuate groove 109a, and the other of the sixth rotating part 1091 and the fourth rotating part 1060 includes a second arcuate block 1063. The second arcuate groove 109a and the second arcuate block 1063 cooperate to rotatably connect the sixth rotating part 1091 and the fourth rotating part 1060. In one embodiment, the sixth rotating part 1091 has a second arcuate groove 109a. The fourth rotating part 1060 includes a second arcuate block 1063, and the second arcuate groove 109a cooperates with the second arcuate block 1063. In other words, the second arcuate groove 109a is provided on the second support member 109, and the second arcuate block 1063 is provided on the second connecting seat 106. The second arcuate block 1063 rotates in contact with the second arcuate groove 109a. Of course, in other embodiments, the second arc groove 109a can be disposed on the second connecting seat 106, and the second arc block 1063 can be disposed on the second support member 109. The cooperation between the second arc groove 109a and the second arc block 1063 enables the rotational connection between the second support member 109 and the second connecting seat 106, allowing the second support member 109 to rotate relative to the second connecting seat 106 along the central axis of the second arc groove 109a. Since the central axis of the second arc groove 109a can be close to or located on the flexible display screen 2, the rotational design of the second support member 109 relative to the second connecting seat 106 is more flexible, facilitating the adjustment of the movement trajectory of the second support member 109 and achieving the flattening and teardrop folding of the flexible display screen 2.

[0061] The second arcuate groove 109a of the second support member 109 includes a third arcuate surface 1091a and a third limiting surface 1091b adjacent to the third arcuate surface 1091a. The second arcuate block 1063 of the second connecting seat 106 includes a fourth arcuate surface 1063a and a fourth limiting surface 1063b adjacent to the fourth arcuate surface 1063a. The third arcuate surface 1091a and the fourth arcuate surface 1063a are at least partially in contact. The third limiting surface 1091b and the fourth limiting surface 1063b are disposed opposite to each other. When the second connecting seat 106 is in the fourth state, the third limiting surface 1091b and the fourth limiting surface 1063b abut against each other. The third limiting surface 1091b and the fourth limiting surface 1063b abut against each other when the second connecting seat 106 is in the fourth state, which can limit the tilt angle of the second support member 109 relative to the base 101, and prevent the tilt angle of the second support member 109 from being too large and pulling the flexible display screen 2.

[0062] Optional, please refer to Figure 29 and Figure 30 The fourth rolling part 1052 and the third rolling part 1043 (see reference) Figure 26One of the four rolling portions 1052 and the third rolling portion 1043 includes a second rolling groove 105b, and the other includes a second rolling column 104c. The second rolling groove 105b and the second rolling column 104c cooperate to enable the fourth rolling portion 1052 and the third rolling portion 1043 to be rolled together. In one embodiment, the third rolling portion 1043 includes the second rolling column 104c, and the fourth rolling portion 1052 has a second rolling groove 105b, which cooperates with the second rolling column 104c. In other words, the second rolling column 104c is disposed on the first driving member 104, the second rolling groove 105b is disposed on the first support member 105, and the second rolling column 104c rolls within the second rolling groove 105b. In this embodiment, the rolling connection between the first driving member 104 and the first support member 105 is achieved through the cooperation of the second rolling groove 105b and the second rolling column 104c. This facilitates the first support member 105 to move relative to the first driving member 104 along a preset trajectory by designing the shape and size of the second rolling groove 105b and the second rolling column 104c, thereby better controlling the motion accuracy of the first support member 105 and realizing the diversification of the motion trajectory of the first support member 105.

[0063] The second rolling groove 105b includes a third limiting wall 105c, a third trajectory wall 105d, a fourth limiting wall 105e, and a fourth trajectory wall 105f connected in sequence. The third limiting wall 105c is located on the side of the fourth limiting wall 105e away from the base 101. The third limiting wall 105c, the third trajectory wall 105d, the fourth limiting wall 105e, and the fourth trajectory wall 105f are all curved. The second rolling column 104c is cylindrical. In the first state, the second rolling column 104c abuts against the third limiting wall 105c. When the first connecting seat 102 and the first driving member 104 are in the first state, the second rolling column 104c abutting against the third limiting wall 105c can restrict the rolling of the first support member 105 relative to the first driving member 104, which is beneficial for flattening the first support member 105. In the second state, the second rolling column 104c abuts against the fourth limiting wall 105e. When the first driving member 104 is in the second state, the second rolling column 104c abuts against the fourth limiting wall 105e, which can restrict the rolling of the first support member 105 relative to the first driving member 104, thus preventing the first support member 105 from pulling the flexible display screen 2 in the second state. When the first support member 105 switches between the first state and the second state, the second rolling column 104c rolls between the third track wall 105d and the fourth track wall 105f.

[0064] Optional, please refer to Figure 29 and Figure 30 The eighth rolling part 1092 and the seventh rolling part 1083 (see reference) Figure 26One of the components includes a fourth rolling groove 109b, and the other of the eighth rolling portion 1092 and the seventh rolling portion 1083 includes a fourth rolling column 108c. The fourth rolling groove 109b and the fourth rolling column 108c cooperate to enable the eighth rolling portion 1092 and the seventh rolling portion 1083 to be rolled together. In one embodiment, the seventh rolling portion 1083 includes the fourth rolling column 108c, and the eighth rolling portion 1092 has a fourth rolling groove 109b, which cooperates with the fourth rolling column 108c. In other words, the fourth rolling column 108c is disposed on the second driving member 108, the fourth rolling groove 109b is disposed on the second support member 109, and the fourth rolling column 108c rolls within the fourth rolling groove 109b. In this embodiment, the rolling connection between the second drive member 108 and the second support member 109 is achieved through the cooperation of the fourth rolling groove 109b and the fourth rolling column 108c. This facilitates the second support member 109 to move relative to the second drive member 108 along a preset trajectory by designing the shape and size of the fourth rolling groove 109b and the fourth rolling column 108c, thereby better controlling the movement accuracy of the second support member 109 and achieving diversification of the movement trajectory of the second support member 109.

[0065] The fourth rolling groove 109b includes a seventh limiting wall 109c, a seventh trajectory wall 109d, an eighth limiting wall 109e, and an eighth trajectory wall 109f connected in sequence. The seventh limiting wall 109c is located on the side of the eighth limiting wall 109e away from the base 101. The seventh limiting wall 109c, seventh trajectory wall 109d, eighth limiting wall 109e, and eighth trajectory wall 109f are all curved. The fourth rolling column 108c is cylindrical. In the third state, the fourth rolling column 108c abuts against the seventh limiting wall 109c. When the second driving member 108 is in the third state, the fourth rolling column 108c abuts against the fifth limiting arm, which can restrict the rolling of the second support member 109 relative to the second driving member 108, facilitating the flattening of the second support member 109. In the fourth state, the fourth rolling column 108c abuts against the eighth limiting wall 109e. When the second drive member 108 is in the fourth state, the fourth rolling column 108c abuts against the sixth limiting arm to restrict the rolling of the second support member 109 relative to the second drive member 108, thus preventing the second support member 109 from pulling on the flexible display screen 2 in the fourth state. When the second support member 109 switches between the third and fourth states, the fourth rolling column 108c rolls between the seventh track wall 109d and the eighth track wall 109f.

[0066] Among them, such as Figure 31As shown, the base 101 has a first receiving space 101a and a second receiving space 101b spaced apart from each other. At least a portion of the first rotating member 103 is located in the first receiving space 101a, and at least a portion of the first driving member 104 is located in the second receiving space 101b. By forming the first receiving space 101a and the second receiving space 101b in the base 101, the first rotating shaft 1010 and the second rotating portion 1041 of the first rotating member 103, the second rotating shaft 1012 and the first driving member 104 can be respectively used to receive the second rotating part 1041, thereby improving the compactness of the rotating shaft mechanism 10 and reducing the volume of the rotating shaft mechanism 10.

[0067] The base 101 has a third receiving space 101c and a fourth receiving space 101d spaced apart from each other. At least a portion of the third rotating member 107 is located in the third receiving space 101c, and at least a portion of the second driving member 108 is located in the fourth receiving space 101d. By forming the third receiving space 101c and the fourth receiving space 101d in the base 101, the third rotating shaft 1013 and the fifth rotating portion 1081 of the third rotating member 107, the fourth rotating shaft 1014 and the second driving member 108 can be respectively used to receive the fifth rotating portion 1081, thereby improving the compactness of the rotating shaft mechanism 10 and reducing the volume of the rotating shaft mechanism 10.

[0068] Further, please refer to Figure 32 and Figure 33The rotating shaft mechanism 10 also includes a second rotating member 114. The second rotating member 114 is located between the base 101 and the first connecting seat 102. In this embodiment, the second rotating member 114 and the first rotating member 103 are arranged along the direction of the central axis M of the rotating shaft mechanism 10. One end of the second rotating member 114 is rotatably connected to the base 101, and the other end of the second rotating member 114 is slidably connected to the first connecting seat 102. For example, the second rotating member 114 and the base 101 can be directly rotatably connected by the fit of a shaft and a hole or the fit of an arc track groove and an arc sliding part, or they can be rotatably connected by other shaft components such as a pin. The second rotating member 114 and the first connecting seat 102 can be slidably connected by the fit of a slide rail and a slider or a slide groove and a slider. The second rotating member 114 is used to move relative to the base 101 to switch between a first state and a second state. In one embodiment, in the first state, the second rotating member 114 is flattened relative to the base 101; in the second state, the second rotating member 114 is folded relative to the base 101. It can be understood that in the first state, both the second rotating member 114 and the first rotating member 103 are flattened relative to the base 101; in the second state, both the second rotating member 114 and the first rotating member 103 are folded relative to the base 101. By providing the second rotating member 114, a rotatable connection is formed between the first connecting seat 102 and the base 101 through the first rotating member 103 and the second rotating member 114. This reduces the assembly gap between the first connecting seat 102, the base 101, the first rotating member 103, and the second rotating member 114, improving the assembly accuracy of the rotating shaft mechanism 10, and thus further enhancing the motion control accuracy of the rotating shaft mechanism 10.

[0069] The second rotating member 114 and the first rotating member 103 may have the same or different structures. In this embodiment, the second rotating member 114 and the first rotating member 103 have roughly the same structure. The second rotating member 114 and the base 101 are rotatably connected by the cooperation of the fifth rotating shaft 1015 and the fifth shaft hole 1140. In this embodiment, the fifth rotating shaft 1015 is a fixed shaft. Of course, in other embodiments, the fifth rotating shaft 1015 may also be a movable shaft. The fifth rotating shaft 1015 is parallel to the central axis M of the rotating shaft mechanism 10. Optionally, the second rotating member 114 has a fifth shaft hole 1140; the fifth rotating shaft 1015 passes through the fifth shaft hole 1140, and both ends of the fifth rotating shaft 1015 are respectively fixed to the base 101. The fifth rotating shaft 1015 and the fifth shaft hole 1140 form a rotating pair between the second rotating member 114 and the base 101, which facilitates the assembly of the second rotating member 114 and the base 101 and facilitates the mass production of the rotating shaft mechanism 10. Of course, in other embodiments, the fifth rotating shaft 1015 may also be integrally formed with either the base 101 or the second rotating member 114.

[0070] One of the second rotating member 114 and the first connecting seat 102 includes a fifth sliding groove 102g, and the other of the second rotating member 114 and the first connecting seat 102 includes a fifth sliding block 1141. The fifth sliding groove 102g and the fifth sliding block 1141 cooperate to allow the first rotating member 103 to slide on the first connecting seat 102. In one embodiment, the second rotating member 114 includes a fifth sliding block 1141, and the first connecting seat 102 also includes a fifth sliding groove 102g. The fifth sliding block 1141 cooperates with the fifth sliding groove 102g. In other words, the fifth sliding groove 102g is located on the first connecting seat 102, and the fifth sliding block 1141 is located on the second rotating member 114, and the fifth sliding block 1141 slides against the fifth sliding groove 102g. Of course, in other embodiments, the fifth sliding block 1141 may be located on the first connecting seat 102, and the fifth sliding groove 102g may be located on the second rotating member 114. In this embodiment, the fifth slider 1141 and the fifth slide groove 102g are both rectangular, so that the second rotating member 114 slides linearly relative to the first connecting seat 102.

[0071] Among them, such as Figure 34 As shown, the first rotation axis of the first rotating member 103 relative to the base 101 is parallel to and not collinear with the second rotation axis of the second rotating member 114 relative to the base 101. In other words, the first rotating shaft 1010 and the fifth rotating shaft 1015 are parallel to and not collinear. Optionally, the first rotating shaft 1010 and the fifth rotating shaft 1015 are offset along the length or thickness direction of the rotating shaft mechanism 10. The length direction of the rotating shaft mechanism 10 is the length direction of the folding housing 1 and the electronic device 100, and the thickness direction of the rotating shaft mechanism 10 is the thickness direction of the folding housing 1 and the electronic device 100. In this application, the first rotation axis of the first rotating member 103 relative to the base 101 can be understood as the first rotating shaft 1010 or the central axis of the first rotating shaft 1010; the second rotation axis of the second rotating member 114 relative to the base 101 can be understood as the fifth rotating shaft 1015 or the central axis of the fifth rotating shaft 1015.

[0072] Since the second rotation axis of the second rotating member 114 relative to the base 101 is parallel and not collinear with the first rotation axis of the first rotating member 103 relative to the base 101, the second rotating member 114 and the first rotating member 103 can rotate in the same direction. At the same time, the fitting clearance between the first connecting seat 102 and the base 101 is reduced, and the rotational play and wobbling of the rotating shaft mechanism 10 are reduced. This further improves the accuracy of the synchronous rotation of the first connecting seat 102, the first rotating member 103, and the second rotating member 114 relative to the base 101, making the motion control of the first housing 11 more precise when the rotating shaft mechanism 10 is applied to the folding housing 1.

[0073] In this embodiment, the first rotating member 103 is slidably connected to the first connecting seat 102 along a first direction, and the second rotating member 114 is slidably connected to the first connecting seat 102 along a second direction. The first and second directions intersect but are not perpendicular. In one embodiment, the first direction can be referred to as the p direction in the accompanying drawings, and the second direction can be referred to as the q direction in the accompanying drawings. By making the first rotating member 103 slidably connected to the first connecting seat 102 along the first direction, and the second rotating member 114 slidably connected to the first connecting seat 102 along the second direction, relative sliding can occur between the first rotating member 103, the second rotating member 114, and the first connecting seat 102. At the same time, the constraint of relative sliding between the first rotating member 103, the second rotating member 114, and the first connecting seat 102 is increased, which can reduce the sliding play and wobbling between the first rotating member 103, the second rotating member 114, and the first connecting seat 102, making the motion control of the first housing 11 more precise when the rotating shaft mechanism 10 is applied to the folding housing 1.

[0074] Please refer to Figure 32 and Figure 33 The rotating shaft mechanism 10 also includes a fourth rotating member 115. The fourth rotating member 115 is located between the base 101 and the second connecting seat 106. In this embodiment, the fourth rotating member 115 and the third rotating member 107 are arranged along the central axis M of the rotating shaft mechanism 10. One end of the fourth rotating member 115 is rotatably connected to the base 101, and the other end is slidably connected to the second connecting seat 106. For example, the fourth rotating member 115 and the base 101 can be directly rotatably connected by a shaft and hole fit or an arc-shaped groove and an arc-shaped sliding part fit, or they can be rotatably connected by other shaft components such as pins. The fourth rotating member 115 and the second connecting seat 106 can be slidably connected by a slide rail and a slider, or a slide groove and a slider fit. The fourth rotating member 115 is used to move relative to the base 101 to switch between the third and fourth states. In one embodiment, in the third state, the fourth rotating member 115 is flattened relative to the base 101; in the fourth state, the fourth rotating member 115 is folded relative to the base 101. It can be understood that in the third state, both the fourth rotating member 115 and the third rotating member 107 are flattened relative to the base 101; in the fourth state, both the fourth rotating member 115 and the third rotating member 107 are folded relative to the base 101. By providing the fourth rotating member 115, a rotational connection is formed between the second connecting seat 106 and the base 101 through the third rotating member 107 and the fourth rotating member 115. This reduces the assembly gap between the second connecting seat 106, the base 101, the third rotating member 107, and the fourth rotating member 115, improving the assembly accuracy of the rotating shaft mechanism 10, and thus further enhancing the motion control accuracy of the rotating shaft mechanism 10.

[0075] The fourth rotating member 115 and the third rotating member 107 can have the same or different structures. In this embodiment, the fourth rotating member 115 and the third rotating member 107 have roughly the same structure. The fourth rotating member 115 and the base 101 are rotatably connected by the cooperation of the sixth rotating shaft 1016 and the sixth shaft hole 1150. In this embodiment, the sixth rotating shaft 1016 is a fixed shaft. Of course, in other embodiments, the sixth rotating shaft 1016 can also be a movable shaft. The sixth rotating shaft 1016 is parallel to the central axis M of the rotating shaft mechanism 10. Optionally, the fourth rotating member 115 has a sixth shaft hole 1150; the sixth rotating shaft 1016 passes through the sixth shaft hole 1150, and both ends of the sixth rotating shaft 1016 are respectively fixed to the base 101. The sixth rotating shaft 1016 and the sixth shaft hole 1150 form a rotating pair between the fourth rotating member 115 and the base 101, which facilitates the assembly of the fourth rotating member 115 and the base 101 and facilitates the mass production of the rotating shaft mechanism 10. Of course, in other embodiments, the sixth rotating shaft 1016 may also be integrally formed with either the base 101 or the fourth rotating member 115.

[0076] One of the fourth rotating member 115 and the second connecting seat 106 includes a sixth sliding groove 106g, and the other of the fourth rotating member 115 and the second connecting seat 106 includes a sixth sliding block 1151. The sixth sliding groove 106g and the sixth sliding block 1151 cooperate to allow the fourth rotating member 115 to be slidably connected to the first connecting seat 102. In one embodiment, the fourth rotating member 115 includes a sixth sliding block 1151, and the second connecting seat 106 also includes a sixth sliding groove 106g. The sixth sliding block 1151 cooperates with the sixth sliding groove 106g. In other words, the sixth sliding groove 106g is disposed on the second connecting seat 106, and the sixth sliding block 1151 is disposed on the fourth rotating member 115, and the sixth sliding block 1151 slides against the sixth sliding groove 106g. Of course, in other embodiments, the sixth sliding block 1151 may be disposed on the second connecting seat 106, and the sixth sliding groove 106g may be disposed on the fourth rotating member 115. In this embodiment, the sixth slider 1151 and the sixth slide groove 106g are both rectangular, so that the fourth rotating member 115 slides linearly relative to the first connecting seat 102.

[0077] Among them, such as Figure 34As shown, the third rotation axis of the third rotating member 107 relative to the base 101 is parallel to and not collinear with the fourth rotation axis of the fourth rotating member 115 relative to the base 101. In other words, the third rotating shaft 1013 is parallel to and not collinear with the sixth rotating shaft 1016. Optionally, the third rotating shaft 1013 and the sixth rotating shaft 1016 are offset along the length or thickness direction of the rotating shaft mechanism 10. In this application, the third rotation axis of the third rotating member 107 relative to the base 101 can be understood as the third rotating shaft 1013 or the central axis of the third rotating shaft 1013; the fourth rotation axis of the fourth rotating member 115 relative to the base 101 can be understood as the sixth rotating shaft 1016 or the central axis of the sixth rotating shaft 1016.

[0078] Since the fourth rotation axis of the fourth rotating member 115 relative to the base 101 is parallel and not collinear with the third rotation axis of the third rotating member 107 relative to the base 101, the fourth rotating member 115 and the third rotating member 107 can rotate in the same direction. At the same time, the fitting clearance between the second connecting seat 106 and the base 101 is reduced, and the rotational play and wobbling of the rotating shaft mechanism 10 are reduced. This further improves the accuracy of the synchronous rotation of the second connecting seat 106, the third rotating member 107, and the fourth rotating member 115 relative to the base 101, making the motion control of the second housing 12 more precise when the rotating shaft mechanism 10 is applied to the folding housing 1.

[0079] In this embodiment, the third rotating member 107 is slidably connected to the second connecting seat 106 along a third direction, and the fourth rotating member 115 is slidably connected to the second connecting seat 106 along a fourth direction. The third and fourth directions intersect but are not perpendicular. In one embodiment, the third direction can be referred to as direction P in the accompanying drawings, and the fourth direction can be referred to as direction Q in the accompanying drawings. By making the third rotating member 107 and the second connecting seat 106 slidably connected along the third direction, and the fourth rotating member 115 and the second connecting seat 106 slidably connected along the fourth direction, relative sliding can occur between the third rotating member 107, the fourth rotating member 115 and the second connecting seat 106. At the same time, the constraint of relative sliding between the third rotating member 107, the fourth rotating member 115 and the second connecting seat 106 is increased, which can reduce the sliding play and wobbling between the third rotating member 107, the fourth rotating member 115 and the second connecting seat 106, so that the rotating shaft mechanism 10 can more accurately control the movement of the second housing 12 when applied to the folding housing 1. Among them, the third direction and the first direction can be symmetrical about the central axis M of the rotating shaft mechanism 10, and the fourth direction and the second direction can be symmetrical about the central axis M of the rotating shaft mechanism 10.

[0080] Furthermore, such as Figure 35As shown, the rotating shaft mechanism 10 also includes a decorative element 116, and the base 101 is housed within the decorative element 116. The decorative element 116 and the base 101 can be integrally formed or fixedly connected. For example, the fixed connection methods between the decorative element 116 and the base 101 include, but are not limited to, threaded connection, snap-fit, welding, riveting, and bonding. In this embodiment, the decorative element 116 is semi-circular. In the first state, the first rotating element 103, the second rotating element 114, the third rotating element 107, and the fourth rotating element 115 are supported on the decorative element 116. In other words, when the rotating shaft mechanism 10 is in a flattened state, the first rotating element 103 and the second rotating element 114 abut against the side of the decorative element 116 facing the first sub-bending area 20 of the flexible display screen 2; the third rotating element 107 and the fourth rotating element 115 abut against the side of the decorative element 116 facing the third sub-bending area 20 of the flexible display screen 2. By providing the decorative element 116, the base 101 can be accommodated. When the rotating shaft mechanism 10 is in the folded state, it has a decorative effect on the appearance of the rotating shaft mechanism 10. When the rotating shaft mechanism 10 is in the flattened state, the first rotating element 103, the second rotating element 114, the third rotating element 107, and the fourth rotating element 115 are supported on the decorative element 116, which can prevent the first rotating element 103, the second rotating element 114, the third rotating element 107, and the fourth rotating element 115 from bending in the opposite direction, thus better realizing the flattening of the rotating shaft mechanism 10.

[0081] The features mentioned above in the specification, claims, and drawings can be arbitrarily combined with each other, provided they are meaningful within the scope of this application. The advantages and features described for the pivot mechanism 10 are correspondingly applied to the folding housing 1 and the electronic device 100. Although embodiments of this application have been shown and described above, it is understood that these embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this application, and such improvements and refinements are also considered to be within the scope of protection of this application.
