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, the hinge structure of foldable electronic devices suffers from low motion precision, 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:

[0005] Base;

[0006] The first connecting seat is located on one side of the base;

[0007] 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 are movable relative to the base to switch between a first state and a second state.

[0008] A first support member is rotatably connected to the first connecting seat and rollwise connected to the first rotating member, or the first support member is rollwise connected to the first connecting seat and rotatably connected to the first rotating member. When the first connecting seat and the first rotating member move relative to the base, the first support member moves relative to the base.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] The rotating mechanism provided in this application includes a base, a first connecting seat, a first rotating 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, with one end of the first rotating member rotatably connected to the base and the other end slidably connected to the first connecting seat, the first connecting seat and the first rotating member can only slide relative to each other and cannot rotate. This facilitates control of the movement of the first connecting seat and the first rotating member relative to the base, improving the movement accuracy of the first connecting seat and the first rotating member when switching between a first state and a second state. Because the first supporting member is rotatably connected to the first connecting seat and rollwise connected to the first rotating member, or rollwise connected to the first connecting seat and rotatably connected to the first rotating member, the first supporting member can move relative to the base under the drive of the first connecting seat and the first rotating member. This facilitates the supporting function of the first supporting member in different states, enabling it to reduce folding gaps in folding shells and electronic devices, improve aesthetic appearance, and support flexible displays in electronic devices when applied to folding shells and electronic devices. In addition, the first support member is in a rolling connection with one of the first connecting seat and the first rotating member, that is, the first support member can slide and rotate relative to one of the first connecting seat and the first rotating member, which is conducive to realizing multiple motion trajectories of the first support member, so as to meet the design requirements and further improve the motion accuracy of the first support member.

[0047] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without creative effort are within the protection scope of this application.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0049] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order.

[0050] 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 direction can be understood as the length direction of the electronic device 100 and the folding shell 1; the Z-axis direction can be understood as the thickness direction of the electronic device 100 and the folding shell 1.

[0051] 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.

[0052] 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 (OLED) 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.

[0053] 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.

[0054] 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.

[0055] 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. 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 is slidably connected to the first connecting seat 102. It can be understood that the first housing 11 achieves its rotatable connection to 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 by 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 by other shaft components such as a pin. The first rotating component 103 and the first connecting seat 102 can be slidably connected by the fit of a slide rail and a slider or the fit of a slide groove and a slider.

[0056] 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.

[0057] 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.

[0058] like Figure 8 As shown, the rotating shaft mechanism 10 also includes a first support member 104. The first support member 104 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 104. For example, the first sub-bending area 20 is bonded to the first support member 104. Of course, in other embodiments, the first sub-bending area 20 and the first support member 104 may not be fixedly connected. The first support member 104 is rotatably connected to the first connecting seat 102 and rollwise connected to the first rotating member 103, or the first support member 104 is rollwise connected to the first connecting seat 102 and rotatably connected to the first rotating member 103. In other words, one end of the first support member 104 is rotatably connected to the first connecting seat 102, and the other end of the first support member 104 is rollwise connected to the first rotating member 103; or, one end of the first support member 104 is rotatably connected to the first rotating member 103, and the other end of the first support member 104 is rollwise connected to the first connecting seat 102. In the following embodiments, one end of the first support member 104 is rotatably connected to the first connecting seat 102, and the other end of the first support member 104 is rollably connected to the first rotating member 103. 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. Specifically, the first support member 104 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-like components such as pins. The first support member 104 and the first rotating member 103 can be rollably connected through the fit of a rolling groove and a rolling column, etc.

[0059] Please refer to Figure 9 and Figure 10 When the first connecting seat 102 and the first rotating member 103 move relative to the base 101, the first supporting member 104 moves relative to the base 101. In one embodiment, in the first state, the first supporting member 104 is flattened relative to the base 101; in the second state, the end of the first supporting member 104 near the base 101 is inclined towards the side near the first connecting seat 102. The side of the first supporting member 104 facing the first sub-bending area 20 of the flexible display screen 2 is flat. In the first state, the first supporting member 104 supports 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 inclination of the end of the first supporting member 104 near the base 101 towards the side near the first connecting seat 102 allows the first housing 11 to move closer to the second housing 12, reducing the gap between the first housing 11 and the second housing 12, which is beneficial for achieving the teardrop-shaped folding of the flexible display screen 2.

[0060] In this configuration, one of the first housing 11, the first connecting seat 102, the first rotating member 103, and the first supporting member 104 can serve as the active component for flattening and folding the left side of the folding housing 1, while the others serve as driven components for the same purpose. When the first housing 11 acts as the active component, the user's external force on the first housing 11 can cause it to rotate relative to the base 101, thereby rotating the first connecting seat 102 and the first rotating member 103 relative to the base 101 to achieve flattening and folding. Since the first supporting member 104 is connected to the first connecting seat 102 and the first rotating member 103, when the first connecting seat 102 and the first rotating member 103 rotate relative to the base 101, they can also cause the first supporting member 104 to move relative to the base 101, thereby flattening and tilting the first supporting member 104. When one of the first connecting seat 102, the first rotating member 103, and the first supporting member 104 acts as the driving member, a corresponding driving structure (such as a motor) can be provided inside the folding shell 1. Through the action of the driving structure, one of the first connecting seat 102, the first rotating member 103, and the first supporting member 104 rotates relative to the base 101, thereby driving the others, including the first shell 11, to rotate relative to the base 101, thus achieving automatic flattening and folding of the left side of the folding shell 1. In this embodiment, to simplify the structure of the folding shell 1, the first shell 11 is used as the driving member for flattening and folding on the left side of the folding shell 1 as an example.

[0061] The rotating shaft mechanism 10 provided in the above embodiment includes a base 101, a first connecting seat 102, a first rotating member 103, and a first support member 104. 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 support member 104 is rotatably connected to one of the first connecting seat 102 and the first rotating member 103, and the other end is rollwise connected to the other of the first connecting seat 102 and the first rotating member 103, the first support member 104 can move relative to the base 101 under the drive of the first connecting seat 102 and the first rotating member 103. This facilitates the support function of the first support member 104 in the first and second states, enabling it to reduce the folding gaps of the folding housing 1 and the electronic device 100 when applied to them, thereby improving the appearance and supporting the flexible display screen 2 of the electronic device 100. In addition, the first support member 104 is rollwise connected to one of the first connecting seat 102 and the first rotating member 103, meaning that the first support member 104 can slide and rotate relative to one of the first connecting seat 102 and the first rotating member 103. This facilitates the realization of various movement trajectories of the first support member 104, meeting design requirements and further improving the movement accuracy of the first support member 104.

[0062] like Figure 11As 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 105 and a third rotating member 106. The second connecting seat 105 is located on the other side of the base 101 away from the first connecting seat 102. It can be understood that the other side of the base 101 is opposite to one side of the base 101. In other words, the other side of the base 101, based on the accompanying drawings of this application, can be understood as the right side of the base 101. The second housing 12 is fixedly connected to the second connecting seat 105. The third rotating member 106 is located between the base 101 and the second connecting seat 105. One end of the third rotating member 106 is rotatably connected to the base 101, and the other end of the third rotating member 106 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 105 and the third rotating member 106. The fixed connection methods between the second housing 12 and the second connecting seat 105 include, but are not limited to, integral connection, threaded connection, snap-fit, welding, riveting, and bonding. The third rotating member 106 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 106 and the second connecting seat 105 can achieve a slidable connection through the fit of a slide rail and a slider or the fit of a slide groove and a slider.

[0063] By fixing the second housing 12 to the second connecting seat 105, the fitting clearance between the second housing 12 and the second connecting seat 105 can be reduced, and the motion transition between the second housing 12 and the second connecting seat 105 can be avoided. This reduces the play in the second housing 12 and the second connecting seat 105, and improves the synchronicity of the rotation of the second housing 12 and the second connecting seat 105 relative to the base 101. By rotatably connecting one end of the third rotating member 106 to the base 101 and slidingly connecting the other end to the second connecting seat 105, while the second housing 12, the second connecting seat 105, and the third rotating member 106 rotate relative to the base 101, the second connecting seat 105 and the third rotating member 106 can only slide relative to each other and cannot rotate. Therefore, the rotational play between the third rotating member 106 and the second connecting seat 105 can be avoided, thereby improving the accuracy of the synchronous rotation of the second housing 12, the second connecting seat 105, and the third rotating member 106 relative to the base 101.

[0064] 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.

[0065] Please refer to Figure 12 and Figure 13The third rotating member 106 and the second connecting seat 105 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 106 and the second connecting seat 105 are flattened relative to the base 101, and at this time, the third rotating member 106 and the second connecting seat 105 are parallel or approximately parallel to the base 101; in the fourth state, the third rotating member 106 and the second connecting seat 105 are folded relative to the base 101, and at this time, the third rotating member 106 and the second connecting seat 105 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 106 and the second connecting seat 105 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.

[0066] like Figure 14 As shown, the rotating shaft mechanism 10 also includes a second support member 107. The second support member 107 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 107. For example, the third sub-bending area 20 is bonded to the second support member 107. Of course, in other embodiments, the third sub-bending area 20 and the second support member 107 may not be fixedly connected. The second support member 107 is rotatably connected to the second connecting seat 105 and rollwise connected to the third rotating member 106, or the second support member 107 rollwise connected to the second connecting seat 105 and rotatably connected to the third rotating member 106. In other words, one end of the second support member 107 is rotatably connected to the second connecting seat 105, and the other end of the second support member 107 rollwise connected to the third rotating member 106; or, one end of the second support member 107 is rotatably connected to the third rotating member 106, and the other end of the second support member 107 rollwise connected to the second connecting seat 105. In the following embodiments, one end of the second support member 107 is rotatably connected to the second connecting seat 105, and the other end of the second support member 107 is rollably connected to the third rotating member 106. The second support member 107 and the second connecting seat 105 can be directly rotatably connected through a shaft and hole fit, or through an arc-shaped groove and an arc-shaped sliding part fit, or through other shaft-like components such as pins. The second support member 107 and the third rotating member 106 can be rollably connected through a rolling groove and rollers, etc.

[0067] Please refer to Figure 15 and Figure 16 When the second connecting seat 105 and the third rotating member 106 move relative to the base 101, the second supporting member 107 moves relative to the base 101. In one embodiment, when the second connecting seat 105 and the third rotating member 106 are in a third state, the second supporting member 107 is flattened relative to the base 101; when the second connecting seat 105 and the third rotating member 106 are in a fourth state, the end of the second supporting member 107 near the base 101 is inclined toward the side near the second connecting seat 105. The side of the second supporting member 107 facing the third sub-bending area 20 of the flexible display screen 2 is flat. In the third state, the second supporting member 107 supports 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 107 near the base 101 is tilted toward the side near the second connecting seat 105, 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.

[0068] In this configuration, one of the second housing 12, the second connecting seat 105, the third rotating member 106, and the second supporting member 107 can serve as the active component for flattening and folding the right side of the folding housing 1, while the others serve as driven components for the same purpose. When the second housing 12 acts as the active component, the user's external force on the second housing 12 can cause it to rotate relative to the base 101, thereby rotating the second connecting seat 105 and the third rotating member 106 relative to the base 101 to achieve flattening and folding. Since the second supporting member 107 is connected to the second connecting seat 105 and the third rotating member 106, when the second connecting seat 105 and the third rotating member 106 rotate relative to the base 101, they can also cause the second supporting member 107 to move relative to the base 101, thereby flattening and tilting the second supporting member 107. When one of the second connecting seat 105, the third rotating member 106, and the second supporting member 107 acts as the driving member, a corresponding driving structure (such as a motor) can be provided inside the folding housing 1. The driving structure enables one of the two components (the second connecting seat 105, the third rotating member 106, and the second supporting member 107) 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 driving 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.

[0069] The rotating shaft mechanism 10 provided in this embodiment also includes a base 101, a second connecting seat 105, a third rotating member 106, and a second support member 107. Since the second connecting seat 105 is located on the other side of the base 101, and the third rotating member 106 is located between the second connecting seat 105 and the base 101, one end of the third rotating member 106 is rotatably connected to the base 101, and the other end is slidably connected to the second connecting seat 105, so that the second connecting seat 105 and the third rotating member 106 can only slide relative to each other and cannot rotate. This is beneficial for controlling the movement of the second connecting seat 105 and the third rotating member 106 relative to the base 101 and improving the movement accuracy of the second connecting seat 105 and the third rotating member 106 when switching between the third state and the fourth state. Since one end of the second support member 107 is rotatably connected to one of the second connecting seat 105 and the third rotating member 106, and the other end is rollwise connected to the other of the second connecting seat 105 and the third rotating member 106, the second support member 107 can move relative to the base 101 under the drive of the second connecting seat 105 and the third rotating member 106. This facilitates the support function of the second support member 107 in the third and fourth states, enabling it to reduce the folding gaps of the folding housing 1 and the electronic device 100 when applied to them, thereby improving the appearance and supporting the flexible display screen 2 of the electronic device 100. Furthermore, the second support member 107 is rollwise connected to one of the second connecting seat 105 and the third rotating member 106, meaning the second support member 107 can slide and rotate relative to one of the second connecting seat 105 and the third rotating member 106. This facilitates the realization of various movement trajectories of the second support member 107, meeting design requirements and further improving the movement accuracy of the second support member 107.

[0070] Furthermore, when the rotating shaft mechanism 10 is in the folded state, the first support member 104, driven by the first connecting seat 102 and the first rotating member 103, can tilt its end near the base 101 toward the side near the first connecting seat 102; the second support member 107, driven by the second connecting seat 105 and the third rotating member 106, can tilt its end near the base 101 toward the side near the second connecting seat 105. That is, the distance between the end of the first support member 104 away from the base 101 and the end of the second support member 107 away from the base 101 is less than the distance between the end of the first support member 104 near the base 101 and the end of the second support member 107 near the base 101. In other words, when the pivot mechanism 10 is in the folded state, the first support member 104 and the second support member 107 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 104 is fixedly connected to the first sub-bending area 20 of the flexible display screen 2, and the second support member 107 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.

[0071] The second connecting seat 105 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 106 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 support member 107 and the first support member 104 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 shell 1 and the electronic device 100. In this embodiment, the second connecting seat 105 and the first connecting seat 102 are symmetrically arranged about the central axis M of the rotating shaft mechanism 10; the third rotating member 106 and the first rotating member 103 are symmetrically arranged about the central axis M of the rotating shaft mechanism 10; and the second support member 107 and the first support member 104 are symmetrically arranged about the central axis M of the rotating shaft mechanism 10.

[0072] Optional, such as Figure 17As shown, the first rotating member 103 includes a first rotating part 1030, a first sliding part 1031, and a first rolling part 1032 connected in sequence. In this application, "connected" includes both direct and indirect connections, which will not be elaborated further. A direct connection refers to two components being integrally formed, or two components being connected through their own structural design, or two components being connected through a connector, such as a snap-fit ​​formed by the fit of a boss and a groove, bonding, welding, threaded connection, etc. An indirect connection refers to two components being connected through other structural components. For example, the first rotating part 1030, the first sliding part 1031, and the first rolling part 1032 are integrally formed; or, the first rotating part 1030 and the first sliding part 1031 are integrally formed, and the first rolling part 1032 is fixedly connected to the first sliding part 1031 through a connector. The first rotating part 1030, the first sliding part 1031, and the first rolling part 1032 are connected in sequence. In other words, the first rolling part 1032 is disposed on the first sliding part 1031. In this embodiment, the first rolling part 1032 is located at the end of the first sliding part 1031 away from the first rotating part 1030. The first rotating part 1030 is rotatably connected to the base 101. The first sliding part 1031 is slidably connected to the first connecting seat 102. The first rolling part 1032 is rollingly connected to the first support member 104.

[0073] In this embodiment, the first rotating part 1030 and the base 101 are rotatably connected via a first rotating shaft 1010. In this embodiment, the first rotating shaft 1010 is a fixed shaft. The first rotating shaft 1010 is parallel to the central axis M of the rotating shaft mechanism 10. Optionally, the first rotating part 1030 has a first shaft hole 1030a; the first rotating shaft 1010 passes through the first shaft hole 1030a, and both ends of the first rotating shaft 1010 are respectively fixed to the base 101. The first rotating shaft 1010 forms a rotating pair between the first rotating member 103 and the base 101, facilitating the assembly of the first rotating member 103 and the base 101, and facilitating mass production of the rotating shaft mechanism 10. Of course, in other embodiments, the first rotating shaft 1010 can also be integrally formed with either the base 101 or the first rotating member 103.

[0074] The third rotating member 106 includes a fifth rotating portion 1060, a third sliding portion 1061, and a fifth rolling portion 1062 connected in sequence. For example, the fifth rotating portion 1060, the third sliding portion 1061, and the fifth rolling portion 1062 are integrally formed; or, the fifth rotating portion 1060 and the third sliding portion 1061 are integrally formed, and the fifth rolling portion 1062 is fixedly connected to the third sliding portion 1061 by a connector. The fifth rotating portion 1060, the third sliding portion 1061, and the fifth rolling portion 1062 are connected in sequence. In other words, the fifth rolling portion 1062 is disposed on the third sliding portion 1061. In the embodiment of this application, the fifth rolling portion 1062 is located at the end of the third sliding portion 1061 away from the fifth rotating portion 1060. The fifth rotating portion 1060 is rotatably connected to the base 101. The third sliding portion 1061 is slidably connected to the second connecting seat 105. The fifth rolling portion 1062 is rollingly connected to the second support member 107.

[0075] The fifth rotating part 1060 is rotatably connected to the base 101 via a third rotating shaft 1013. In this embodiment, the third rotating shaft 1013 is a fixed shaft. The third rotating shaft 1013 and the first rotating shaft 1010 are symmetrically arranged along the central axis M of the rotating shaft mechanism 10. Optionally, the fifth rotating part 1060 has a third shaft hole 1060a; the third rotating shaft 1013 passes through the third shaft hole 1060a, and both ends of the third rotating shaft 1013 are respectively fixed to the base 101. The third rotating shaft 1013 forms a rotating pair between the third rotating member 106 and the base 101, which facilitates the assembly of the third rotating member 106 and the base 101 and facilitates the mass production of the rotating shaft mechanism 10. Of course, in other embodiments, the third rotating shaft 1013 can also be integrally formed with either the base 101 or the third rotating member 106.

[0076] Optional, please refer to Figure 18 and Figure 19The first support member 104 includes a first main body portion 1040, a second rotating portion 1041, and a second rolling portion 1042. At least a portion of the first main body portion 1040 covers the first connecting seat 102. In other words, at least a portion of the first main body portion 1040 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 first main body portion 1040 covers the first connecting seat 102, and another portion of the first main body portion 1040 covers one side of the base 101; or, the first main body portion 1040 completely covers the first connecting seat 102; or, a portion of the first main body portion 1040 covers the first connecting seat 102, and another portion of the first main body portion 1040 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 example is that the first main body portion 1040 completely covers the first connecting seat 102. By covering the first main body 1040 onto the first connecting seat 102, 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 second rotating part 1041 and the second rolling part 1042 are both located on the side of the first main body 1040 facing the first connecting seat 102. The second rotating part 1041 is rotatably connected to the first connecting seat 102. The second rolling part 1042 is rotatably connected to the first rolling part 1032. Since the first rolling part 1032 is connected to the first sliding part 1031, and the first sliding part 1031 is slidably connected to the first connecting seat 102, by locating both the second rotating part 1041 and the second rolling part 1042 on the side of the main body facing the first connecting seat 102, it is advantageous to achieve a rotatable connection between the second rotating part 1041 and the first connecting seat 102, and a rotatable connection between the second rolling part 1042 and the first rolling part 1032. In addition, by placing the second rotating part 1041 and the second rolling part 1042 on the side of the main body facing the first connecting seat 102, the distance between the first support member 104 and the first connecting seat 102 can be reduced, thereby improving the structural compactness of the rotating shaft mechanism 10 and facilitating the thinning and miniaturization of the rotating shaft mechanism 10.

[0077] Please refer to Figure 20 and Figure 21One of the second rolling part 1042 and the first rolling part 1032 includes a first rolling groove 104a, and the other of the second rolling part 1042 and the first rolling part 1032 includes a first rolling column 103a. The first rolling groove 104a and the first rolling column 103a cooperate to enable the second rolling part 1042 and the first rolling part 1032 to be in a rolling connection. In one embodiment, the first rolling part 1032 includes the first rolling column 103a, and the second rolling part 1042 has the first rolling groove 104a, which cooperates with the first rolling column 103a. In other words, the first rolling column 103a is disposed on the first rotating member 103, the first rolling groove 104a is disposed on the first supporting member 104, and the first rolling column 103a rolls within the first rolling groove 104a. In this embodiment, the rolling connection between the first rotating member 103 and the first support member 104 is achieved through the cooperation of the first rolling groove 104a and the first rolling column 103a. This facilitates the design of the shape and size of the first rolling groove 104a and the first rolling column 103a, enabling the first support member 104 to move relative to the first rotating member 103 along a preset trajectory. This allows for better control of the movement accuracy of the first support member 104 and the diversification of the movement trajectory of the first support member 104.

[0078] The first rolling groove 104a includes a first limiting wall 104b, a first trajectory wall 104c, a second limiting wall 104d, and a second trajectory wall 104e connected in sequence. The first limiting wall 104b is located on the side of the second limiting wall 104d away from the base 101. The first limiting wall 104b, the first trajectory wall 104c, the second limiting wall 104d, and the second trajectory wall 104e are all curved. The first rolling column 103a is cylindrical. In the first state, the first rolling column 103a abuts against the first limiting wall 104b. When the first rotating member 103 is in the first state, the first rolling column 103a abuts against the first limiting arm, which can restrict the rolling of the first support member 104 relative to the first rotating member 103, facilitating the flattening of the first support member 104. In the second state, the first rolling column 103a abuts against the second limiting wall 104d. When the first rotating member 103 is in the second state, the first rolling column 103a abuts against the second limiting arm to restrict the rolling of the first support member 104 relative to the first rotating member 103, thus preventing the first support member 104 from pulling the flexible display screen 2 in the second state. When the first support member 104 switches between the first state and the second state, the first rolling column 103a rolls between the first track wall 104c and the second track wall 104e.

[0079] Please refer to Figure 18 and Figure 19The second support member 107 includes a second main body portion 1070, a sixth rotating portion 1071, and a sixth rolling portion 1072. At least a portion of the second main body portion 1070 covers the second connecting seat 105. In other words, at least a portion of the second main body portion 1070 is located on the side of the second connecting seat 105 facing the third sub-bending area 20 of the flexible display screen 2. For example, a portion of the second main body portion 1070 covers the second connecting seat 105, and another portion of the second main body portion 1070 covers the other side of the base 101; or, the second main body portion 1070 completely covers the second connecting seat 105; or, a portion of the second main body portion 1070 covers the second connecting seat 105, and another portion of the second main body portion 1070 extends toward the side of the second connecting seat 105 away from the base 101 (the side where the second housing 12 is located). In the following embodiments, the second main body portion 1070 completely covers the second connecting seat 105 as an example. By covering the second main body 1070 onto the second connecting seat 105, 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 1071 and the sixth rolling part 1072 are both located on the side of the second main body 1070 facing the second connecting seat 105. The sixth rotating part 1071 is rotatably connected to the second connecting seat 105. The sixth rolling part 1072 is rotatably connected to the fifth rolling part 1062. Since the sixth rolling part 1072 is connected to the third sliding part 1061, and the third sliding part 1061 is slidably connected to the second connecting seat 105, by locating both the sixth rotating part 1071 and the sixth rolling part 1072 on the side of the second main body 1070 facing the second connecting seat 105, it is advantageous to achieve a rotatable connection between the sixth rotating part 1071 and the second connecting seat 105, and a rotatable connection between the sixth rolling part 1072 and the fifth rolling part 1062. Furthermore, by placing the sixth rotating part 1071 and the sixth rolling part 1072 on the side of the main body facing the second connecting seat 105, the distance between the second support member 107 and the second connecting seat 105 can be reduced, thereby improving the structural compactness of the rotating shaft mechanism 10 and facilitating the thinning and miniaturization of the rotating shaft mechanism 10.

[0080] Please refer to Figure 20 and Figure 21One of the sixth rolling portion 1072 and the fifth rolling portion 1062 includes a third rolling groove 107a, and the other of the sixth rolling portion 1072 and the fifth rolling portion 1062 includes a third rolling column 106a. The third rolling groove 107a and the third rolling column 106a cooperate to enable the sixth rolling portion 1072 and the fifth rolling portion 1062 to be rolled together. In one embodiment, the fifth rolling portion 1062 includes the third rolling column 106a, and the sixth rolling portion 1072 has the third rolling groove 107a, which cooperates with the third rolling column 106a. In other words, the third rolling column 106a is disposed on the third rotating member 106, the third rolling groove 107a is disposed on the second support member 107, and the third rolling column 106a rolls within the third rolling groove 107a. In this embodiment, the rolling connection between the third rotating member 106 and the second support member 107 is achieved through the cooperation of the third rolling groove 107a and the third rolling column 106a. This facilitates the second support member 107 to move relative to the third rotating member 106 along a preset trajectory by designing the shape and size of the third rolling groove 107a and the third rolling column 106a, thereby better controlling the movement accuracy of the second support member 107 and achieving diversification of the movement trajectory of the second support member 107.

[0081] The third rolling groove 107a includes a fifth limiting wall 107b, a fifth trajectory wall 107c, a sixth limiting wall 107d, and a sixth trajectory wall 107e connected in sequence. The fifth limiting wall 107b is located on the side of the sixth limiting wall 107d away from the base 101. The fifth limiting wall 107b, fifth trajectory wall 107c, sixth limiting wall 107d, and sixth trajectory wall 107e are all curved. The third rolling column 106a is cylindrical. In the third state, the third rolling column 106a abuts against the fifth limiting wall 107b. When the third rotating member 106 is in the third state, the third rolling column 106a abuts against the fifth limiting arm, which can restrict the rolling of the second support member 107 relative to the third rotating member 106, facilitating the flattening of the second support member 107. In the fourth state, the third rolling column 106a abuts against the sixth limiting wall 107d. When the third rotating member 106 is in the fourth state, the third rolling column 106a abuts against the sixth limiting arm, which can restrict the rolling of the second support member 107 relative to the third rotating member 106, thus preventing the second support member 107 from pulling the flexible display screen 2 in the fourth state. When the second support member 107 switches between the third and fourth states, the third rolling column 106a rolls between the fifth track wall 107c and the sixth track wall 107e.

[0082] Among them, such as Figure 22 As shown, the first connecting seat 102 includes a third rotating part 1020 and a second sliding part 1021. The third rotating part 1020 and the second sliding part 1021 are arranged along the direction of the central axis M of the rotating shaft mechanism 10.

[0083] Optionally, one of the second rotating part 1041 and the third rotating part 1020 includes a first arcuate groove 104f, and the other of the second rotating part 1041 and the third rotating part 1020 includes a first arcuate block 102a. The first arcuate groove 104f and the first arcuate block 102a cooperate to rotatably connect the second rotating part 1041 and the third rotating part 1020. In one embodiment, the second rotating part 1041 has a first arcuate groove 104f. The third rotating part 1020 includes a first arcuate block 102a, and the first arcuate groove 104f cooperates with the first arcuate block 102a. In other words, the first arcuate groove 104f is provided on the first support member 104, and the first arcuate block 102a is provided on the first connecting seat 102. The first arcuate block 102a rotates in contact with the first arcuate groove 104f. Of course, in other embodiments, the first arc groove 104f can be disposed on the first connecting seat 102, and the first arc block 102a can be disposed on the first support member 104. The first support member 104 and the first connecting seat 102 are rotatably connected through the cooperation of the first arc groove 104f and the first arc block 102a, thereby enabling the first support member 104 to rotate relative to the first connecting seat 102 along the central axis of the first arc groove 104f. Since the central axis of the first arc groove 104f can be close to or located on the flexible display screen 2, the rotational design of the first support member 104 relative to the first connecting seat 102 is more flexible, facilitating the adjustment of the movement trajectory of the first support member 104 and realizing the flattening and teardrop folding of the flexible display screen 2.

[0084] The first arc groove 104f of the first support member 104 includes a first arc surface and a first limiting surface adjacent to the first arc surface. The first arc block 102a of the first connecting seat 102 includes a second arc surface and a second limiting surface adjacent to the second arc surface. The first arc surface and the second arc surface are at least partially in contact. The first limiting surface and the second limiting surface are arranged opposite to each other. When the rotating shaft mechanism 10 is in the second state, the first limiting surface and the second limiting surface abut against each other. The abutment of the first limiting surface and the second limiting surface in the second state can limit the tilt angle of the first support member 104 relative to the base 101, and prevent the tilt angle of the first support member 104 from being too large, thus avoiding pulling on the flexible display screen 2.

[0085] One of the first sliding portion 1031 and the second sliding portion 1021 includes a first sliding groove 102b, and the other of the first sliding portion 1031 and the second sliding portion 1021 includes a first slider 103f. The first sliding groove 102b and the first slider 103f cooperate to allow the first sliding portion 1031 and the second sliding portion 1021 to be slidably connected. In one embodiment, the first sliding portion 1031 includes the first slider 103f, and the second sliding portion 1021 includes the first sliding groove 102b. The first slider 103f cooperates with the first sliding groove 102b. In other words, the first sliding groove 102b is disposed on the first connecting seat 102, and the first slider 103f is disposed on the first rotating member 103, and the first slider 103f rotates in contact with the first sliding groove 102b. Of course, in other embodiments, the first slider 103f may be disposed on the first connecting seat 102, and the first sliding groove 102b may be disposed on the first rotating member 103. In this embodiment, the first slider 103f and the first groove 102b are both rectangular, so that the first rotating member 103 slides linearly relative to the first connecting seat 102.

[0086] like Figure 23 As shown, the second connecting seat 105 includes a seventh rotating part 1050 and a fourth sliding part 1051. The seventh rotating part 1050 and the fourth sliding part 1051 are arranged along the direction of the central axis M of the rotating shaft mechanism 10.

[0087] Optionally, one of the sixth rotating part 1071 and the seventh rotating part 1050 includes a second arcuate groove 107f, and the other of the sixth rotating part 1071 and the seventh rotating part 1050 includes a second arcuate block 105a. The second arcuate groove 107f and the second arcuate block 105a cooperate to rotatably connect the sixth rotating part 1071 and the seventh rotating part 1050. In one embodiment, the sixth rotating part 1071 has a second arcuate groove 107f. The seventh rotating part 1050 includes a second arcuate block 105a, and the second arcuate groove 107f cooperates with the second arcuate block 105a. In other words, the second arcuate groove 107f is provided on the second support member 107, and the second arcuate block 105a is provided on the second connecting seat 105. The second arcuate block 105a rotates in contact with the second arcuate groove 107f. Of course, in other embodiments, the second arc groove 107f can be disposed on the second connecting seat 105, and the second arc block 105a can be disposed on the second support member 107. The rotational connection between the second support member 107 and the second connecting seat 105 achieved through the cooperation of the second arc groove 107f and the second arc block 105a allows the second support member 107 to rotate relative to the second connecting seat 105 along the central axis of the second arc groove 107f. Since the central axis of the second arc groove 107f can be close to or located on the flexible display screen 2, the rotational design of the second support member 107 relative to the second connecting seat 105 is more flexible, facilitating the adjustment of the movement trajectory of the second support member 107 and realizing the flattening and teardrop folding of the flexible display screen 2.

[0088] The second arc groove 107f of the second support member 107 includes a third arc surface and a third limiting surface adjacent to the third arc surface. The second arc block 105a of the second connecting seat 105 includes a fourth arc surface and a fourth limiting surface adjacent to the fourth arc surface. The third arc surface and the fourth arc surface are at least partially in contact. The third limiting surface and the fourth limiting surface are arranged opposite to each other. When the rotating shaft mechanism 10 is in the second state, the third limiting surface and the fourth limiting surface abut against each other. The abutment of the third limiting surface and the fourth limiting surface in the second state can limit the tilt angle of the second support member 107 relative to the base 101, and prevent the tilt angle of the second support member 107 from being too large, thus avoiding pulling on the flexible display screen 2.

[0089] One of the fourth sliding portion 1051 and the third sliding portion 1061 includes a second sliding groove 105b, and the other of the fourth sliding portion 1051 and the third sliding portion 1061 includes a second slider 106f. The second sliding groove 105b and the second slider 106f cooperate to allow the fourth sliding portion 1051 and the third sliding portion 1061 to be slidably connected. In one embodiment, the third sliding portion 1061 includes a first slider 103f, and the fourth sliding portion 1051 includes a second sliding groove 105b. The second slider 106f cooperates with the second sliding groove 105b. In other words, the second sliding groove 105b is disposed on the second connecting seat 105, and the second slider 106f is disposed on the third rotating member 106, and the second slider 106f rotates in contact with the second sliding groove 105b. Of course, in other embodiments, the second slider 106f may be disposed on the second connecting seat 105, and the second sliding groove 105b may be disposed on the third rotating member 106. In this embodiment, the second slider 106f and the second slide groove 105b are both rectangular, so that the third rotating member 106 slides linearly relative to the second connecting seat 105.

[0090] Furthermore, such as Figure 24As shown, the rotating shaft mechanism 10 also includes a first driving member 108. One end of the first driving member 108 is rotatably connected to one of the base 101 and the first connecting seat 102, and the other end of the first driving member 108 is rollingly connected to the other of the base 101 and the first connecting seat 102. In other words, one end of the first driving member 108 is rotatably connected to the base 101, and the other end of the first driving member 108 is rollingly connected to the first connecting seat 102; or, one end of the first driving member 108 is rotatably connected to the first connecting seat 102, and the other end of the first driving member 108 is rollingly connected to the base 101. In the following embodiments, the example is that one end of the first driving member 108 is rotatably connected to the base 101, and the other end of the first driving member 108 is rollingly connected to the first connecting seat 102. The first driving member 108 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-like components such as pins. The first driving component 108 and the first connecting seat 102 can be rolled together by the cooperation of rolling grooves and rolling columns.

[0091] Please refer to Figure 25 and Figure 26 When the first connecting seat 102 moves relative to the base 101, the first driving member 108 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 108 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 108 is folded relative to the base 101. In this embodiment, by setting the first driving member 108, one end of the first driving member 108 is rotatably connected to one of the base 101 and the first connecting seat 102, and the other end of the first driving member 108 is rollwise connected to the other of the base 101 and the first connecting seat 102. The movement of the first connecting seat 102 can be controlled through the cooperation relationship between the first driving member 108 and the base 101 and the first connecting seat 102, thereby controlling the movement and power transmitted from the first connecting seat 102 to the first support member 104, so as to assist the first connecting seat 102 and the first rotating member 103 in controlling the movement of the first support member 104. In addition, the first connecting seat 102 can be hovered relative to the base 101 through the cooperation relationship between the first driving member 108, the base 101, and the first connecting seat 102, thereby realizing the intermediate hovering state of the first housing 11.

[0092] Among them, such as Figure 27As shown, the first driving member 108 and the first rotating member 103 are arranged along the central axis M of the rotating shaft mechanism 10. The first driving member 108 includes a fourth rotating part 1080, which is rotatably connected to the base 101 through the cooperation of a second rotating shaft 1012 and a second shaft hole 1081. In this embodiment, the second rotating shaft 1012 is a fixed shaft. The second rotating shaft 1012 is parallel to the central axis M of the rotating shaft mechanism 10. Optionally, the first driving member 108 has a second shaft hole 1081. The second rotating shaft 1012 passes through the second shaft hole 1081, 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 108 and the base 101, which facilitates the assembly of the first driving member 108 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 108.

[0093] like Figure 24 As shown, the rotating shaft mechanism 10 also includes a second driving member 109. One end of the second driving member 109 is rotatably connected to one of the base 101 and the second connecting seat 105, and the other end of the second driving member 109 is rollingly connected to the other of the base 101 and the second connecting seat 105. In other words, one end of the second driving member 109 is rotatably connected to the base 101, and the other end of the second driving member 109 is rollingly connected to the second connecting seat 105; or, one end of the second driving member 109 is rotatably connected to the second connecting seat 105, and the other end of the second driving member 109 is rollingly connected to the base 101. In the following embodiments, the example is that one end of the second driving member 109 is rotatably connected to the base 101, and the other end of the second driving member 109 is rollingly connected to the second connecting seat 105. The second driving member 109 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 driving component 109 and the second connecting seat 105 can be rolled together by the cooperation of the rolling groove and the rolling column.

[0094] Please refer to Figure 25 and Figure 26When the second connecting seat 105 moves relative to the base 101, the second driving member 109 moves relative to the base 101. In one embodiment, when the second connecting seat 105 and the third rotating member 106 are in the third state, the second driving member 109 is flattened relative to the base 101; when the second connecting seat 105 and the third rotating member 106 are in the fourth state, the second driving member 109 is folded relative to the base 101. In this embodiment, by setting the second driving member 109, one end of the second driving member 109 is rotatably connected to one of the base 101 and the second connecting seat 105, and the other end of the second driving member 109 is rollwise connected to the other of the base 101 and the second connecting seat 105. The movement of the second connecting seat 105 can be controlled through the cooperation relationship between the second driving member 109 and the base 101 and the second connecting seat 105, thereby controlling the movement and power transmitted from the second connecting seat 105 to the second support member 107, so as to assist the second connecting seat 105 and the third rotating member 106 in controlling the movement of the second support member 107. In addition, the second connecting seat 105 can be hovered relative to the base 101 through the cooperation relationship between the second driving member 109 and the base 101 and the second connecting seat 105, thereby realizing the intermediate hovering state of the second housing 12.

[0095] Among them, such as Figure 27 As shown, the second driving member 109 and the second rotating member 114 are arranged along the central axis M of the rotating shaft mechanism 10. The second driving member 109 includes an eighth rotating part 1090, which is rotatably connected to the base 101 through the engagement of a fourth rotating shaft 1014 and a fourth shaft hole 1091. In this embodiment, the fourth rotating shaft 1014 is a fixed shaft. The fourth rotating shaft 1014 is parallel to the central axis M of the rotating shaft mechanism 10. Optionally, the second driving member 109 has a fourth shaft hole 1091. The fourth rotating shaft 1014 passes through the fourth shaft hole 1091, 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 109 and the base 101, which facilitates the assembly of the second driving member 109 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 109.

[0096] Furthermore, such as Figure 27As shown, the first connecting seat 102 also includes a third rolling portion 1022. The third rotating portion 1020, the second sliding portion 1021, and the third rolling portion 1022 are arranged sequentially. Specifically, the third rotating portion 1020, the second sliding portion 1021, and the third rolling portion 1022 are arranged sequentially along the central axis M of the rotating shaft mechanism 10. The third rotating portion 1020, the second sliding portion 1021, and the third rolling portion 1022 are connected sequentially. For example, the third rotating portion 1020, the second sliding portion 1021, and the third rolling portion 1022 are integrally formed; or, the third rotating portion 1020 and the second sliding portion 1021 are integrally formed, and the third rolling portion 1022 is fixedly connected to the side of the second sliding portion 1021 opposite to the third rotating portion 1020 by a connector.

[0097] The first driving member 108 is tactically connected to the third rolling part 1022. Specifically, the first driving member 108 further includes a fourth rolling part 1082 connected to the fourth rotating part 1080. One of the fourth rolling part 1082 and the third rolling part 1022 includes a second rolling groove 102c, and the other of the fourth rolling part 1082 and the third rolling part 1022 includes a second rolling column 108a. The second rolling groove 102c and the second rolling column 108a cooperate to tactically connect the fourth rolling part 1082 and the third rolling part 1022. In one embodiment, the third rolling part 1022 includes the second rolling groove 102c, and the fourth rolling part 1082 includes the second rolling column 108a. The second rolling groove 102c cooperates with the second rolling column 108a. In other words, the second rolling column 108a is disposed on the first driving member 108, the second rolling groove 102c is disposed on the first connecting seat 102, and the second rolling column 108a rolls within the second rolling groove 102c. In this embodiment, the rolling connection between the first driving member 108 and the first connecting seat 102 is achieved through the cooperation of the second rolling groove 102c and the second rolling column 108a. This facilitates the first driving member 108 to assist the first connecting seat 102 in controlling the motion accuracy of the first support member 104 by designing the shape and size of the second rolling groove 102c and the second rolling column 108a, thereby achieving diversification of the motion trajectory of the first support member 104.

[0098] Please refer to Figure 28 and Figure 29The second rolling groove 102c includes a third limiting wall 102d, a third trajectory wall 102e, a fourth limiting wall 102f, and a fourth trajectory wall 102g connected in sequence. The third limiting wall 102d is located on the side of the fourth limiting wall 102f away from the base 101. The third limiting wall 102d, the third trajectory wall 102e, the fourth limiting wall 102f, and the fourth trajectory wall 102g are all curved. The second rolling column 108a is cylindrical. When the first connecting seat 102 is in the first state, the second rolling column 108a abuts against the third limiting wall 102d. When the first connecting seat 102 is in the first state, the second rolling column 108a abuts against the third limiting arm, which can restrict the rolling between the first driving member 108 and the first connecting seat 102, facilitating the flattening of the first support member 104 and the first driving member 108. When the first connecting seat 102 is in the second state, the first rolling column 103a abuts against the fourth limiting wall 102f. When the first connecting seat 102 is in the second state, the second rolling column 108a abuts against the fourth limiting arm, which can limit the rolling between the first driving member 108 and the first connecting seat 102, preventing the first connecting seat 102 from shaking in the second state and affecting the support of the first support member 104 for the flexible display screen 2. When the first driving member 108 switches between the first state and the second state, the second rolling column 108a rolls between the third track wall 102e and the fourth track wall 102g.

[0099] like Figure 27 As shown, the second connecting seat 105 also includes a seventh rolling portion 1052. The seventh rotating portion 1050, the fourth sliding portion 1051, and the seventh rolling portion 1052 are arranged sequentially. Specifically, the seventh rotating portion 1050, the fourth sliding portion 1051, and the seventh rolling portion 1052 are arranged sequentially along the central axis M of the rotating shaft mechanism 10. The seventh rotating portion 1050, the fourth sliding portion 1051, and the seventh rolling portion 1052 are connected sequentially. For example, the seventh rotating portion 1050, the fourth sliding portion 1051, and the seventh rolling portion 1052 are integrally formed; or, the seventh rotating portion 1050 and the fourth sliding portion 1051 are integrally formed, and the seventh rolling portion 1052 is fixedly connected to the side of the fourth sliding portion 1051 opposite to the third rotating portion 1020 via a connector.

[0100] The second driving member 109 is tactically connected to the seventh rolling part 1052. Specifically, the second driving member 109 further includes an eighth rolling part 1092 connected to the seventh rotating part 1050. One of the eighth rolling part 1092 and the seventh rolling part 1052 includes a fourth rolling groove 105c, and the other of the eighth rolling part 1092 and the seventh rolling part 1052 includes a fourth rolling column 109a. The fourth rolling groove 105c and the fourth rolling column 109a cooperate to enable the eighth rolling part 1092 and the seventh rolling part 1052 to be tactically connected. In one embodiment, the seventh rolling part 1052 includes a fourth rolling groove 105c, and the eighth rolling part 1092 includes a fourth rolling column 109a. The fourth rolling groove 105c cooperates with the fourth rolling column 109a. In other words, the fourth rolling column 109a is disposed on the second driving member 109, the fourth rolling groove 105c is disposed on the second connecting seat 105, and the fourth rolling column 109a rolls within the fourth rolling groove 105c. In this embodiment, the rolling connection between the second drive member 109 and the second connecting seat 105 is achieved through the cooperation of the fourth rolling groove 105c and the fourth rolling column 109a. This facilitates the second drive member 109 to assist the second connecting seat 105 in controlling the motion accuracy of the second support member 107 by designing the shape and size of the fourth rolling groove 105c and the fourth rolling column 109a, thereby achieving diversification of the motion trajectory of the second support member 107.

[0101] Please refer to Figure 28 and Figure 29 The fourth rolling groove 105c includes a seventh limiting wall 105d, a seventh trajectory wall 105e, an eighth limiting wall 105f, and an eighth trajectory wall 105g connected in sequence. The seventh limiting wall 105d is located on the side of the eighth limiting wall 105f away from the base 101. The seventh limiting wall 105d, the seventh trajectory wall 105e, the eighth limiting wall 105f, and the eighth trajectory wall 105g are all curved. The fourth rolling column 109a is cylindrical. When the second connecting seat 105 is in the third state, the fourth rolling column 109a abuts against the seventh limiting wall 105d. When the second connecting seat 105 is in the third state, the fourth rolling column 109a abuts against the seventh limiting arm, which can restrict the rolling between the second driving member 109 and the second connecting seat 105, facilitating the flattening of the second support member 107 and the second driving member 109. When the second connecting seat 105 is in the fourth state, the first rolling column 103a abuts against the eighth limiting wall 105f. When the second connecting seat 105 is in the fourth state, the fourth rolling column 109a abuts against the eighth limiting arm, which can limit the rolling between the second driving member 109 and the second connecting seat 105, preventing the second connecting seat 105 from shaking in the fourth state and affecting the support of the second support member 107 for the flexible display screen 2. When the second connecting seat 105 switches between the third and fourth states, the fourth rolling column 109a rolls between the seventh track wall 105e and the eighth track wall 105g.

[0102] Among them, such as Figure 30 As 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 part 1030 is located in the first receiving space 101a, and at least a portion of the fourth rotating part 1080 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 part 1030 of the first rotating shaft 1010 and the first rotating member 103, and the fourth rotating part 1080 of the second rotating shaft 1012 and the first driving member 108 can be respectively used to receive the first rotating part 1030 of the first rotating shaft 1010 and the first rotating member 103, and the fourth rotating part 1080 of the second rotating shaft 1012 and the first driving member 108, thereby improving the compactness of the rotating shaft mechanism 10 and reducing the volume of the rotating shaft mechanism 10.

[0103] 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 fifth rotating part 1060 is located in the third receiving space 101c, and at least a portion of the eighth rotating part 1090 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 fifth rotating part 1060 of the third rotating shaft 1013 and the second rotating member 114106, and the eighth rotating part 1090 of the fourth rotating shaft 1014 and the second driving member 109 can be respectively used to receive the fifth rotating part 1060 of the second rotating member 114106 and the eighth rotating part 1090 of the second driving member 109, thereby improving the compactness of the rotating shaft mechanism 10 and reducing the volume of the rotating shaft mechanism 10.

[0104] Further, please refer to Figure 31 and Figure 32The 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.

[0105] The structure of the second rotating member 114 can be the same as or different from that of the first rotating member 103. In one embodiment, the second rotating member 114 includes a connected ninth rotating part 1140 and a fifth sliding part 1141. Optionally, the ninth rotating part 1140 and the fifth sliding part 1141 are integrally formed. The ninth rotating part 1140 is rotatably connected to the base 101 via a fifth rotating shaft 1015. In this embodiment, the fifth rotating shaft 1015 is a fixed shaft. The fifth rotating shaft 1015 is parallel to the central axis M of the rotating shaft mechanism 10. Optionally, the ninth rotating part 1140 has a fifth shaft hole; the fifth rotating shaft 1015 passes through the fifth shaft hole, and both ends of the fifth rotating shaft 1015 are respectively fixed to the base 101. The fifth rotating shaft 1015 forms 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. The first connecting seat 102 further includes a sixth sliding portion 1023. The fifth sliding portion 1141 and the sixth sliding portion 1023 are slidably connected. Optionally, one of the fifth sliding portion 1141 and the sixth sliding portion 1023 includes a third sliding groove 102h, and the other of the fifth sliding portion 1141 and the sixth sliding portion 1023 includes a third sliding block 114a. The third sliding groove 102h cooperates with the third sliding block 114a to slidably connect the fifth sliding portion 1141 and the sixth sliding portion 1023. In one embodiment, the fifth sliding portion 1141 includes a third sliding block 114a, and the sixth sliding portion 1023 includes a third sliding groove 102h. The third sliding block 114a cooperates with the third sliding groove 102h. In other words, the third slide groove 102h is disposed on the first connecting seat 102, and the third slider 114a is disposed on the second rotating member 114. The third slider 114a rotates in contact with the third slide groove 102h. Of course, in other embodiments, the third slider 114a can be disposed on the first connecting seat 102, and the third slide groove 102h can be disposed on the second rotating member 114. In the embodiments of this application, both the third slider 114a and the third slide groove 102h are rectangular, so that the second rotating member 114 slides linearly relative to the first connecting seat 102. The sixth sliding part 1023 can be located between the third rotating part 1020 and the second sliding part 1021, or between the second sliding part 1021 and the third rolling part 1022, or on the side of the third rotating part 1020 away from the second sliding part 1021, or on the side of the third rolling part 1022 away from the second sliding part 1021. In this embodiment, the second rotating member 114 is located on the side of the first rotating member 103 away from the first driving member 108, and the sixth sliding part 1023 is located between the second sliding part 1021 and the third rotating part 1020.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] Please refer to Figure 31 and Figure 32The 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 105. In this embodiment, the fourth rotating member 115 and the third rotating member 106 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 105. 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 105 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 106 are flattened relative to the base 101; in the fourth state, both the fourth rotating member 115 and the third rotating member 106 are folded relative to the base 101. By providing the fourth rotating member 115, a rotational connection is formed between the second connecting seat 105 and the base 101 through the third rotating member 106 and the fourth rotating member 115. This reduces the assembly gap between the second connecting seat 105, the base 101, the third rotating member 106, 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.

[0110] Optionally, the fourth rotating member 115 has the same structure as the second rotating member 114 and is symmetrically arranged along the central axis M of the rotating shaft mechanism 10. In one embodiment, the fourth rotating member 115 includes a connected tenth rotating part 1150 and a seventh sliding part 1151. Optionally, the tenth rotating part 1150 and the seventh sliding part 1151 are integrally formed. The tenth rotating part 1150 is rotatably connected to the base 101 via a sixth rotating shaft 1016. In this embodiment, the sixth rotating shaft 1016 is a fixed shaft. The sixth rotating shaft 1016 is parallel to the central axis M of the rotating shaft mechanism 10. Specifically, the tenth rotating part 1150 has a sixth shaft hole; the sixth rotating shaft 1016 passes through the sixth shaft hole, and both ends of the sixth rotating shaft 1016 are respectively fixed to the base 101. A rotating pair is formed between the fourth rotating member 115 and the base 101 via the sixth rotating shaft 1016, 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 can also be integrally formed with either the base 101 or the fourth rotating member 115. The second connecting seat 105 also includes an eighth sliding portion 1053. The seventh sliding portion 1151 and the eighth sliding portion 1053 are slidably connected. Optionally, one of the seventh sliding portion 1151 and the eighth sliding portion 1053 includes a fourth sliding groove 105h, and the other includes a fourth sliding block 115a. The fourth sliding groove 105h cooperates with the fourth sliding block 115a to slidably connect the seventh sliding portion 1151 and the eighth sliding portion 1053. In one embodiment, the seventh sliding portion 1151 includes the fourth sliding block 115a, and the eighth sliding portion 1053 includes the fourth sliding groove 105h. The fourth slider 115a cooperates with the fourth slide groove 105h. In other words, the fourth slide groove 105h is provided on the second connecting seat 105, and the fourth slider 115a is provided on the fourth rotating member 115, with the fourth slider 115a rotating in contact with the fourth slide groove 105h. Of course, in other embodiments, the fourth slider 115a can be provided on the second connecting seat 105, and the fourth slide groove 105h can be provided on the fourth rotating member 115. In this embodiment, both the fourth slider 115a and the fourth slide groove 105h are rectangular, so that the fourth rotating member 115 slides linearly relative to the second connecting seat 105. The eighth sliding part 1053 can be located between the seventh rotating part 1050 and the fourth sliding part 1051, or between the fourth sliding part 1051 and the seventh rolling part 1052, or on the side of the seventh rotating part 1050 away from the fourth sliding part 1051, or on the side of the seventh rolling part 1052 away from the fourth sliding part 1051. In this embodiment, the fourth rotating member 115 is located on the side of the third rotating member 106 that is away from the second driving member 109, and the eighth sliding part 1053 is located between the fourth sliding part 1051 and the seventh rotating part 1050.

[0111] The third rotation axis of the third rotating member 106 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 106 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.

[0112] 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 106 relative to the base 101, the fourth rotating member 115 and the third rotating member 106 can rotate in the same direction. At the same time, the fit clearance between the second connecting seat 105 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 105, the third rotating member 106, 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.

[0113] In this embodiment, the third rotating member 106 is slidably connected to the second connecting seat 105 along a third direction, and the fourth rotating member 115 is slidably connected to the second connecting seat 105 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 106 and the second connecting seat 105 slidably connected along the third direction, and the fourth rotating member 115 and the second connecting seat 105 slidably connected along the fourth direction, relative sliding can occur between the third rotating member 106, the fourth rotating member 115 and the second connecting seat 105. At the same time, the constraint of relative sliding between the third rotating member 106, the fourth rotating member 115 and the second connecting seat 105 is increased, which can reduce the sliding play and wobbling between the third rotating member 106, the fourth rotating member 115 and the second connecting seat 105, 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.

[0114] Furthermore, such as Figure 33As 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 106, 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 106 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 106, 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 106, and the fourth rotating element 115 from bending in the opposite direction, thus better realizing the flattening of the rotating shaft mechanism 10.

[0115] 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.
