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 presents complex interrelationships between components, making design difficult and hindering mass production. Summary of the Invention

[0003] This application provides a simple rotating shaft mechanism, a folding housing, and an electronic device that are conducive to mass production.

[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 is fixedly connected to the first connecting seat. The first rotating member and the first connecting seat are used to move relative to the base between a first position and a second position.

[0008] A first support member has one end movably connected to the base and the other end rotatably connected to the first connecting seat. When the first connecting seat rotates 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 rotatably connected to the base. The first housing and the second housing rotate relative to the base to realize the flattening and folding of the folding housing.

[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 shaft 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, one end of the first rotating member is rotatably connected to the base, and the other end of the first rotating member is fixedly connected to the first connecting seat, so that the first rotating member and the first connecting seat can rotate synchronously relative to the base. The first rotating member and the first connecting seat are fixedly connected. Compared with sliding connection, rotating connection, rolling connection, etc., this can reduce the design difficulty, simplify the structure of the rotating shaft mechanism, and facilitate the mass production of the rotating shaft mechanism. Furthermore, since one end of the first support member is movably connected to the base and the other end of the first support member is rotatably connected to the first connecting seat, the first support member can move relative to the base when the first connecting seat moves relative to the base. Thus, when the rotating shaft mechanism is applied to folding housings and electronic devices, the first support member can be easily flattened when the folding housing is in a flattened state, which can support the flexible display screen and enhance the stress on the flexible display screen. When the folding housing is in a folded state, the first support member can form a preset accommodating space, which helps to reduce the folding gap of the folding housing and electronic devices, improve the appearance, and increase the bending control of the flexible display screen in the electronic device, which can reduce the creases of the flexible display screen.

[0049] 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.

[0050] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment 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.

[0051] 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.

[0052] 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, the electronic device 100 can 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 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 the flattened state, the flexible display screen 2 and the folding housing 1 are in the 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 1The coordinate system shown can be understood as follows: the X-axis can be understood as the length direction of the electronic device 100; the Y-axis can be understood as the width direction of the electronic device 100; and the Z-axis can be understood as the thickness direction of the electronic device 100.

[0053] 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.

[0054] 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.

[0055] 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 201, a second sub-bending area 202, and a third sub-bending area 203 arranged sequentially. It can be understood that the first non-bending area 21, the first sub-bending area 201, the second sub-bending area 202, the third sub-bending area 203, and the second non-bending area 22 are arranged sequentially. When the flexible display screen 2 is folded, the first sub-bending area 201 and the third sub-bending area 203 are positioned opposite each other. A first gap is formed between the end of the second sub-bending area 202 connecting to the first sub-bending area 201 and the end of the second sub-bending area 202 connecting to the third sub-bending area 203. A second gap is formed between the end of the first sub-bending area 201 connecting to the first non-bending area 21 and the end of the third sub-bending area 203 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 spacing can be referred to as dashed segment a in the figure, and the second spacing can be referred to as dashed segment b in the figure. The second sub-bending area 202 is approximately arc-shaped.

[0056] Please refer to Figures 3 to 5 ,in, Figure 3 An exploded view of the folding housing 1 and the flexible display screen 2 in a flattened state in the electronic device 100 provided in the embodiments of this application; Figure 4 This is a schematic diagram of the folded shell 1 in the folded state provided in the embodiments of this application; Figure 5This 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 housing 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; the first extension portion 1102 and the second extension portion 1202 are used to support the pivot mechanism 10. When the folding housing 1 is in a folded state, the first support plate 112 and the second support plate 121 are disposed 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 portion 1102 and the second extension portion 1202 are disposed opposite to each other, and the space between the first extension portion 1102, the second extension portion 1202 and the pivot mechanism 10 is used to accommodate the bending area 20 of the flexible display screen 2.

[0057] Please refer to Figures 6 to 8 The rotating shaft mechanism 10 includes a base 101, a first connecting seat 102, a first rotating member 103, and a first supporting member 104. 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 fixedly connected to the first connecting seat 102. It can be understood that the first housing 11 achieves its rotatable connection with the base 101 through the first connecting seat 102 and the first rotating member 103. The fixed connection methods between the first housing 11 and the first connecting seat 102 include, but are not limited to, integral connection, threaded connection, snap-fit, welding, riveting, and bonding. The fixed connection methods between the first rotating component 103 and the first connecting seat 102 include, but are not limited to, integral connection, threaded connection, snap-fit, welding, riveting, and bonding. By fixing the first housing 11 to the first connecting seat 102 and the first rotating component 103 to the first connecting seat 102, the clearance between the first housing 11 and the first connecting seat 102 can be reduced, and the movement transition between the first housing 11 and the first connecting seat 102 can be avoided. Similarly, the clearance between the first connecting seat 102 and the first rotating component 103 can be reduced, and the movement transition between the first connecting seat 102 and the first rotating component 103 can be avoided. This reduces the play-offs and wobble among the first housing 11, the first connecting seat 102, and the first rotating component 103, improving the synchronicity of their rotation relative to the base 101. The first rotating member 103 and the first connecting seat 102 are movable relative to the base 101 between a first position and a second position. In one embodiment, in the first position, the first rotating member 103 and the first connecting seat 102 are flattened relative to the base 101; in the second position, the first rotating member 103 and the first connecting seat 102 are folded relative to the base 101. In other words, in the first position, the first housing 11 is in a flattened state; in the second position, the first housing 11 is in a folded state.

[0058] The first support member 104 is used to support the first sub-bending area 201 of the flexible display screen 2. In one embodiment, the first sub-bending area 201 is fixedly connected to the first support member 104. For example, the first sub-bending area 201 is bonded to the first support member 104. Of course, in other embodiments, the first sub-bending area 201 and the first support member 104 may not be fixedly connected. At least a portion of the first support member 104 covers the first connecting seat 102. In other words, at least a portion of the first support member 104 is located on the side of the first connecting seat 102 facing the first sub-bending area 201 of the flexible display screen 2. Optionally, a portion of the first support member 104 covers the first connecting seat 102, and another portion of the first support member 104 covers one side of the base 101; or, the first support member 104 completely covers the first connecting seat 102; or, a portion of the first support member 104 covers the first connecting seat 102, and another portion of the first support member 104 extends toward the first support plate 112 of the first housing 11. In the following embodiments, a portion of the first support member 104 covers the first connecting seat 102, while another portion of the first support member 104 covers one side of the base 101. One end of the first support member 104 is movably connected to the base 101, and the other end of the first support member 104 is rotatably connected to the first connecting seat 102. The movable connection between one end of the first support member 104 and the base 101 can include, but is not limited to, rotational connection, sliding connection, rolling connection, or movable connection through other structural components. The other end of the first support member 104 and the first connecting seat 102 can be directly rotatably connected through the fit of a shaft and hole, the fit of an arc-shaped groove and an arc-shaped sliding part, or through other shaft-like components such as a pin. The first support member 104 is used to move relative to the base 101 under the drive of the first connecting seat 102. In one embodiment, the first support member 104 is flattened when the folded shell 1 is in a flattened state, and when the folded shell 1 is in a folded state, the end of the first support member 104 near the base 101 is inclined towards the side near the first connecting seat 102. The first support member 104 is flat on one side facing the first sub-bending area 201 of the flexible display screen 2. When the folded housing 1 is in the flattened state, it supports the first sub-bending area 201 of the flexible display screen 2 to improve the stress on the first sub-bending area 201. When the folded housing 1 is in the folded state, the end of the first support member 104 near the base 101 is inclined towards the side near the first connecting seat 102, which allows the first housing 11 to be closer to the second housing 12, reducing the gap between the first housing 11 and the second housing 12 when the folded housing 1 is in the folded state.

[0059] In this configuration, one of the first housing 11 and the first rotating member 103 can serve as the active member for flattening and folding the left side of the folding housing 1, while the other serves as the driven member for the same purpose. When the first housing 11 acts as the active member, the rotation of the first housing 11 relative to the base 101 is achieved by the external force applied by the user, which in turn drives the rotation of the first connecting seat 102 and the first rotating member 103 relative to the base 101, thereby achieving flattening and folding. Since the first support member 104 is rotatably connected to the first housing 11, when the first housing 11 rotates under the external force applied by the user, it can also drive the first support member 104 to move, thereby achieving flattening and tilting of the first support member 104. When the first rotating member 103 acts as the active member, a corresponding driving structure (e.g., a motor) can be installed inside the folding shell 1. The driving structure enables the first rotating member 103 to rotate relative to the base 101, thereby driving the first connecting seat 102 and the first shell 11 to rotate relative to the base 101, thus achieving automatic flattening and folding of the folding shell 1. Since the first supporting member 104 is rotatably connected to the first shell 11, when the first shell 11 rotates under the drive of the first rotating member 103, it can drive the first supporting member 104 to move, thereby achieving flattening and tilting of the first supporting member 104. In this embodiment, to simplify the structure of the folding shell 1, the first shell 11 is used as the active member on the left side of the folding shell 1 for flattening and folding.

[0060] 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 supporting member 104. Since the first connecting seat 102 is located on one side of the base 101, one end of the first rotating member 103 is rotatably connected to the base 101, and the other end of the first rotating member 103 is fixedly connected to the first connecting seat 102, so that the first rotating member 103 and the first connecting seat 102 can rotate synchronously relative to the base 101. The first rotating member 103 and the first connecting seat 102 are fixedly connected. Compared with sliding connection, rotating connection, rolling connection, etc., the design difficulty can be reduced, the structure of the rotating shaft mechanism 10 can be simplified, and the mass production of the rotating shaft mechanism 10 is beneficial. Furthermore, since one end of the first support member 104 is movably connected to the base 101 and the other end of the first support member 104 is rotatably connected to the first connecting seat 102, the first support member 104 is flattened when the folded housing 1 is in a flattened state. When applied to the electronic device 100, it can support the flexible display screen 2 in a flattened state, thereby enhancing the stress on the flexible display screen 2. When the folded housing 1 is in a folded state, the end of the first support member 104 near the base 101 is tilted towards the side near the first connecting seat 102. When applied to the folded housing 1 and the electronic device 100, it helps to reduce the folding gap of the folded housing 1 and the electronic device 100, improves the appearance, and increases the bending control of the flexible display screen 2 in the electronic device 100, thereby reducing the creases of the flexible display screen 2.

[0061] Please refer to Figures 8 to 10The second housing 12 is rotatably connected to the base 101. The first housing 11 and the second housing 12 rotate relative to the base 101 to achieve the flattening and folding of the folding housing 1. The way in which the second housing 12 is rotatably connected to the base 101 can be the same as or different from the way the first housing 11 is rotatably connected to the base 101. In this embodiment, the way in which the second housing 12 is rotatably connected to the base 101 is the same as the way in which the first housing 11 is rotatably connected to the base 101 is taken as an example. In other embodiments, the second housing 12 and the base 101 can be directly rotatably connected by the fit of a shaft and a hole, the fit of an arc track groove and an arc sliding part, or by other shaft components such as a pin. Specifically, the rotating shaft mechanism 10 also includes a second connecting seat 105, a second rotating member 106, and a second support member 107. The second connecting seat 105 is located on the other side of the base 101. The other side of the base 101 is opposite to one side of the base 101. In other words, the other side of the base 101 can be understood as the right side of the base 101 based on the accompanying drawings of this application. The second housing 12 is fixedly connected to the second connecting seat 105. The second rotating member 106 is located between the base 101 and the second connecting seat 105. One end of the second rotating member 106 is rotatably connected to the base 101, and the other end is fixedly connected to the second connecting seat 105. 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 second 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 fixed connection methods between the second rotating member 106 and the second connecting seat 105 include, but are not limited to, integral connection, threaded connection, snap-fit, welding, riveting, and bonding. By fixing the second housing 12 to the second connecting seat 105 and the second rotating member 106 to the second connecting seat 105, the fit clearance between the second housing 12 and the second connecting seat 105 can be reduced, and the movement transition between the second housing 12 and the second connecting seat 105 can be avoided. Similarly, by reducing the fit clearance between the second connecting seat 105 and the second rotating member 106, and avoiding the movement transition between the second connecting seat 105 and the second rotating member 106, the play-off wobbling among the second housing 12, the second connecting seat 105, and the second rotating member 106 can be improved, thus enhancing the synchronicity of the rotation of the second housing 12, the second connecting seat 105, and the second rotating member 106 relative to the base 101. The second rotating member 106 and the second connecting seat 105 are used to move relative to the base 101 between a third position and a fourth position. In one embodiment, in the third position, the second rotating member 106 and the second connecting seat 105 are flattened relative to the base 101; in the fourth position, the second rotating member 106 and the second connecting seat 105 are folded relative to the base 101. In other words, in the third position, the second housing 12 is in a flattened state; in the fourth position, the second housing 12 is in a folded state.

[0062] The second support member 107 is used to support the third sub-bending area 203 of the flexible display screen 2. In one embodiment, the third sub-bending area 203 is fixedly connected to the second support member 107. For example, the third sub-bending area 203 is bonded to the second support member 107. Of course, in other embodiments, the third sub-bending area 203 and the second support member 107 may not be fixedly connected. The second support member 107 at least partially covers the second connecting seat 105. In other words, the second support member 107 is at least partially located on the side of the second connecting seat 105 facing the third sub-bending area 203 of the flexible display screen 2. Optionally, a portion of the second support member 107 covers the second connecting seat 105, and another portion of the second support member 107 covers one side of the base 101; or, the second support member 107 completely covers the second connecting seat 105; or, a portion of the second support member 107 covers the second connecting seat 105, and another portion of the second support member 107 extends toward the second support plate 121 of the second housing 12. In the following embodiments, a portion of the second support member 107 covers the second connecting seat 105, while another portion of the second support member 107 covers one side of the base 101. One end of the second support member 107 is movably connected to the base 101, and the other end of the second support member 107 is rotatably connected to the second connecting seat 105. The movable connection between one end of the second support member 107 and the base 101 includes, but is not limited to, rotational connection, sliding connection, rolling connection, or movable connection through other structural components. The other end of the second support member 107 and the second connecting seat 105 can be directly rotatably connected through the fit of a shaft and hole, the fit of an arc-shaped groove and an arc-shaped sliding part, or through other shaft components such as a pin. The second support member 107 is used to move relative to the base 101 under the drive of the second connecting seat 105. In one embodiment, the second support member 107 is flattened when the folded shell 1 is in a flattened state, and when the folded shell 1 is in a folded state, the end of the second support member 107 near the base 101 is tilted towards the side near the second connecting seat 105. The second support member 107 is flat on the side facing the third sub-bending area 203 of the flexible display screen 2. When the folded housing 1 is in the flattened state, it supports the third sub-bending area 203 of the flexible display screen 2 to improve the stress on the third sub-bending area 203. When the folded housing 1 is in the folded state, the end of the second support member 107 near the base 101 is inclined towards the side near the second connecting seat 105, which can bring the second housing 12 closer to the first housing 11, further reducing the gap between the second housing 12 and the first housing 11 when the folded housing 1 is in the folded state.

[0063] In this configuration, one of the second housing 12 and the second rotating member 106 can serve as the active member for flattening and folding the right side of the folding housing 1, while the other serves as the driven member for the same purpose. When the second housing 12 acts as the active member, the rotation of the second housing 12 relative to the base 101 is achieved by the external force applied by the user, which in turn drives the rotation of the second connecting seat 105 and the second rotating member 106 relative to the base 101, thereby achieving flattening and folding. Since the second support member 107 is rotatably connected to the second housing 12, when the second housing 12 rotates under the external force applied by the user, it can also drive the second support member 107 to move, thereby achieving flattening and tilting of the second support member 107. When the second rotating member 106 acts as the driving member, a corresponding driving structure (e.g., a motor) can be provided inside the folding shell 1. The driving structure enables the second rotating member 106 to rotate relative to the base 101, thereby driving the second connecting seat 105 and the second shell 12 to rotate relative to the base 101, achieving automatic flattening and folding of the folding shell 1. Since the second support member 107 is rotatably connected to the second shell 12, when the second shell 12 rotates under the drive of the second rotating member 106, it can drive the second support member 107 to move, achieving flattening and tilting of the second support member 107. In this embodiment, to simplify the structure of the folding shell 1, the second shell 12 is used as the driving member for flattening and folding on the right side of the folding shell 1. In this embodiment, the rotation of the first shell 11 relative to the base 101 and the rotation of the second shell 12 relative to the base 101 are independent of each other. Of course, in other embodiments, when the first shell 11 and the second shell 12 need to rotate synchronously, a corresponding synchronization mechanism can be provided inside the folding shell 1.

[0064] The rotating shaft mechanism 10 provided in this embodiment also includes a second connecting seat 105, a second rotating member 106, and a second supporting member 107. Since the second connecting seat 105 is located on the other side of the base 101, one end of the second rotating member 106 is rotatably connected to the base 101, and the other end of the second rotating member 106 is fixedly connected to the second connecting seat 105, so that the second rotating member 106 and the second connecting seat 105 can rotate synchronously relative to the base 101. The second rotating member 106 and the second connecting seat 105 are fixedly connected. Compared with sliding connection, rotating connection, rolling connection and other methods, the design difficulty can be reduced, the structure of the rotating shaft mechanism 10 can be simplified, and the mass production of the rotating shaft mechanism 10 is beneficial. Furthermore, when the folded shell 1 is in the folded state, the first support member 104, driven by the first connecting seat 102, can tilt its end near the base 101 toward the side near the first connecting seat 102. Similarly, the second support member 107, driven by the second connecting seat 105, can tilt its end near the base 101 toward the side near the second connecting seat 105. In other words, 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 ends of the first support member 104 and the second support member 107 near the base 101. In other words, when the folded shell 1 is in the folded state, the first support member 104 and the second support member 107 form a narrower space away from the base 101 and a wider space near the base 101, facilitating the close proximity of the first shell 11 and the second shell 12 and achieving seamless folding of the folded shell 1. The first sub-bending area 201 of the flexible display screen 2 is fixedly connected to the first support member 104, and the third sub-bending area 203 of the flexible display screen 2 is fixedly connected to the second support member 107. The first housing 11 and the second housing 12 are arranged opposite to each other when the folded housing 1 is in the folded state, that is, the first non-bending area 21 and the second non-bending area 22 of the flexible display screen 2 are arranged opposite to each other. The base 101 is not connected to the second sub-bending area 202 of the flexible display screen 2. The second sub-bending area 202 is freely bent, so that the flexible display screen 2 can be approximately teardrop-shaped when folded.

[0065] The second rotating member 106 and the first rotating member 103 can be symmetrical or asymmetrical along the central axis of the rotating shaft mechanism 10. The central axis of the rotating shaft mechanism 10 can be referred to as axis M in the attached drawings. In this application, the direction of the central axis M of the rotating shaft mechanism 10 can also be understood as the width direction of the folding housing 1 and the electronic device 100. In this embodiment, the second rotating member 106 and the first rotating member 103 are offset along the direction of the central axis M of the rotating shaft mechanism 10 to distribute the force on the rotating shaft mechanism 10 and reduce the radial dimension of the rotating shaft mechanism 10.

[0066] Please refer to Figures 11 to 14One end of the first rotating member 103 is rotatably connected to the base 101 via a circular arc track groove and a circular arc sliding part. The central axis of the circular arc track groove between the first rotating member 103 and the base 101 is the rotation axis of the first rotating member 103 relative to the base 101. In this embodiment, the rotational connection between the first rotating member 103 and the base 101 is achieved through the cooperation of the circular arc track groove and the circular arc sliding part. The design of the circular arc track groove allows the rotation axis of the first rotating member 103 to be closer to the theoretically designed position, thus giving the first rotating member 103 a precise motion trajectory. Furthermore, the rotational connection between the first rotating member 103 and the base 101 achieved through the cooperation of the circular arc track groove and the circular arc sliding part also prevents the first rotating member 103 from piercing or damaging the flexible display screen 2 when its rotation axis is close to it. Optionally, the first rotating member 103 includes an arcuate portion, and the base 101 includes an arcuate groove. The first rotating member 103 and the base 101 are rotatably connected through the engagement of the arcuate portion and the arcuate groove. Since the base 101 has a relatively large dimension along the thickness direction of the folded shell 1, it is easier to machine the arcuate groove on the base 101. The first rotating member 103 can be selected as a rotating arm or rotating rod, which has a smaller dimension and is easier to form an arcuate portion. Of course, in other embodiments, an arcuate groove can be provided in the first rotating member 103, and an arcuate portion can be provided in the base 101 to achieve a rotatable connection between the first rotating member 103 and the base 101.

[0067] One of the base 101 and the first rotating member 103 has a first arcuate groove, a first arcuate block and a second arcuate block disposed within the first arcuate groove, and the first arcuate block and the second arcuate block are disposed opposite to each other. The other of the base 101 and the first rotating member 103 includes a first arcuate portion, a first trajectory groove and a second trajectory groove disposed on the first arcuate portion, and the first trajectory groove and the second trajectory groove are disposed opposite to each other. The first arcuate portion slides within the first arcuate groove, the first arcuate block slides within the first trajectory groove, and the second arcuate block slides within the second trajectory groove. In one embodiment, please refer to... Figures 13 to 15The base 101 has a first arcuate groove 1010, a first arcuate block 101a and a second arcuate block 101b disposed within the first arcuate groove 1010. The first arcuate block 101a and the second arcuate block 101b are arranged opposite to each other. For example, the first arcuate block 101a and the second arcuate block 101b are arranged opposite to each other along the direction of the central axis M of the rotating shaft mechanism 10. The first rotating member 103 includes a first arcuate portion 1030, a first track groove 1031 and a second track groove 1032 disposed on the first arcuate portion 1030. The first track groove 1031 and the second track groove 1032 are arranged opposite to each other. For example, the first track groove 1031 and the second track groove 1032 are arranged opposite to each other along the direction of the central axis M of the rotating shaft mechanism 10. Optionally, both the first track groove 1031 and the second track groove 1032 are arcuate track grooves. The first arc portion 1030 slides within the first arc groove 1010, the first arc block 101a slides within the first track groove 1031, and the second arc block 101b slides within the second track groove 1032. In this embodiment, by setting opposing first arc blocks 101a and second arc blocks 101b in the first arc groove 1010 of the base 101, and setting opposing first track grooves 1031 and second track grooves 1032 in the first arc portion 1030 of the first rotating member 103, the first arc portion 1030 slides in the first arc groove 1010, the first arc block 101a slides in the first track groove 1031, and the second arc block 101b slides in the second track groove 1032. While realizing the rotational connection between the first rotating member 103 and the base 101, the opposing first arc blocks 101a and second arc blocks 101b form a further cooperation with the opposing first track grooves 1031 and second track grooves 1032, which can reduce the cooperation gap and assembly error between the first rotating member 103 and the base 101. In addition, a constraint is formed during the rotation of the first rotating member 103 relative to the base 101, which can control the movement accuracy of the first rotating member 103. Of course, in other embodiments, only one of the first arc block 101a and the second arc block 101b may be provided in the first arc groove 1010 of the base 101, and one of the first track groove 1031 and the second track groove 1032 may be provided on the first arc portion 1030 of the first rotating member 103, so that the first arc block 101a slides in the first track groove 1031 or the second arc block 101b slides in the second track groove 1032, thereby realizing the assembly control of the first rotating member 103 and the base 101 and the motion control of the first rotating member 103.In other embodiments, the groove wall of the first arc groove 1010 of the base 101 can form at least one trajectory groove, and at least one arc block can be formed on the first arc portion 1030 of the first rotating member 103, so that the first arc groove 1010 and the first arc portion 1030 cooperate, and at the same time, the arc block on the first arc portion 1030 cooperates with the trajectory groove of the first arc groove 1010, thereby realizing the assembly control of the first rotating member 103 and the base 101 and the motion control of the first rotating member 103.

[0068] Please refer to Figures 16 to 19 One end of the second rotating member 106 is rotatably connected to the base 101 via a circular arc track groove and a circular arc sliding part. The central axis of the circular arc track groove between the second rotating member 106 and the base 101 is the rotation axis of the second rotating member 106 relative to the base 101. In this embodiment, the rotational connection between the second rotating member 106 and the base 101 is achieved through the cooperation of the circular arc track groove and the circular arc sliding part. The design of the circular arc track groove allows the rotation axis of the second rotating member 106 to be closer to the theoretically designed position, thus giving the second rotating member 106 a precise motion trajectory. Furthermore, the rotational connection between the second rotating member 106 and the base 101 via the cooperation of the circular arc track groove and the circular arc sliding part also prevents the second rotating member 106 from piercing or damaging the flexible display screen 2 when its rotation axis is close to it. Optionally, the second rotating member 106 includes an arcuate portion, and the base 101 includes an arcuate groove. The second rotating member 106 and the base 101 are rotatably connected through the engagement of the arcuate portion and the arcuate groove. Since the base 101 has a relatively large dimension along the thickness direction of the folded shell 1, it is easier to machine the arcuate groove on the base 101. The second rotating member 106 can be selected as a rotating arm or rotating rod, which has a smaller dimension and is easier to form an arcuate portion. Of course, in other embodiments, an arcuate groove can be provided in the second rotating member 106, and an arcuate portion can be provided in the base 101 to achieve a rotatable connection between the second rotating member 106 and the base 101.

[0069] One of the base 101 and the second rotating member 106 has a third arcuate groove, a fifth arcuate block and a sixth arcuate block disposed within the third arcuate groove, the fifth arcuate block and the sixth arcuate block being disposed opposite to each other. The other of the base 101 and the second rotating member 106 includes a third arcuate portion, a fifth trajectory groove and a sixth trajectory groove disposed on the third arcuate portion, the fifth trajectory groove and the sixth trajectory groove being disposed opposite to each other. The third arcuate portion slides within the third arcuate groove, the fifth arcuate block slides within the fifth trajectory groove, and the sixth arcuate block slides within the sixth trajectory groove. In one embodiment, please refer to... Figures 18 to 20The base 101 also has a third arcuate groove 1012, a fifth arcuate block 101c, and a sixth arcuate block 101d disposed within the third arcuate groove 1012. The fifth arcuate block 101c and the sixth arcuate block 101d are arranged opposite to each other. For example, the fifth arcuate block 101c and the sixth arcuate block 101d are arranged opposite to each other along the direction of the central axis M of the rotating shaft mechanism 10. The second rotating member 106 includes a third arcuate portion 1060, a fifth trajectory groove 1061, and a sixth trajectory groove 1062 disposed on the third arcuate portion 1060. The fifth trajectory groove 1061 and the sixth trajectory groove 1062 are arranged opposite to each other. For example, the fifth trajectory groove 1061 and the sixth trajectory groove 1062 are arranged opposite to each other along the direction of the central axis M of the rotating shaft mechanism 10. Optionally, both the fifth trajectory groove 1061 and the sixth trajectory groove 1062 are arcuate trajectory grooves. The third arc portion 1060 slides within the third arc groove 1012, the fifth arc block 101c slides within the fifth track groove 1061, and the sixth arc block 101d slides within the sixth track groove 1062. In this embodiment, by providing opposing fifth arc blocks 101c and sixth arc blocks 101d within the third arc groove 1012 of the base 101, and opposing fifth trajectory grooves 1061 and sixth trajectory grooves 1062 within the third arc portion 1060 of the second rotating member 106, the third arc portion 1060 slides within the third arc groove 1012, the fifth arc block 101c slides within the fifth trajectory groove 1061, and the sixth arc block 101d slides within the sixth trajectory groove 1062. While achieving a rotatable connection between the second rotating member 106 and the base 101, the opposing fifth arc blocks 101c and sixth arc blocks 101d further cooperate with the opposing fifth trajectory grooves 1061 and sixth trajectory grooves 1062, which can reduce the cooperation gap and assembly error between the second rotating member 106 and the base 101. Furthermore, by forming a constraint during the rotation of the second rotating member 106 relative to the base 101, the movement accuracy of the second rotating member 106 can be controlled. Of course, in other embodiments, only one of the fifth arc block 101c and the sixth arc block 101d may be provided in the third arc portion 1060 of the base 101, and one of the fifth trajectory groove 1061 and the sixth trajectory groove 1062 may be provided on the third arc portion 1060 of the second rotating member 106, so that the fifth arc block 101c slides in the fifth trajectory groove 1061 or the sixth arc block 101d slides in the sixth trajectory groove 1062, thereby realizing the assembly control of the second rotating member 106 and the base 101 and the motion control of the second rotating member 106.In other embodiments, the groove wall of the third arc groove 1012 of the base 101 can form at least one trajectory groove, and at least one arc block can be formed on the third arc portion 1060 of the second rotating member 106, so that the third arc groove 1012 and the third arc portion 1060 cooperate, and at the same time, the arc block on the third arc portion 1060 cooperates with the trajectory groove of the third arc groove 1012, thereby realizing the assembly control of the second rotating member 106 and the base 101 and the motion control of the second rotating member 106.

[0070] Please refer to Figure 21 and Figure 22 The first connecting seat 102 has a first opening 1021. In one embodiment, the first opening 1021 extends through the first connecting seat 102 along the X-axis. At least one end of the first rotating member 103 is disposed within the first opening 1021. By disposing the other end of the first rotating member 103 within the first opening 1021, the contact area between the first rotating member 103 and the first connecting seat 102 can be increased, thereby improving the fixing effect between the first rotating member 103 and the first connecting seat 102. Furthermore, disposing the other end of the first rotating member 103 within the first opening 1021 facilitates the flattening of the first rotating member 103, the first connecting seat 102, and the first housing 11, ensuring the distance between the first rotating member 103 and the flexible display screen 2, and preventing the first rotating member 103 from colliding with the flexible display screen 2 during movement.

[0071] The second connecting base 105 has a third opening 1051. In one embodiment, the third opening 1051 extends through the second connecting base 105 along the length of the electronic device 100. The other end of the second rotating member 106 is disposed within the third opening 1051. By disposing the other end of the second rotating member 106 within the third opening 1051, the contact area between the second rotating member 106 and the second connecting base 105 can be increased, thereby improving the fixing effect between the second rotating member 106 and the second connecting base 105. Furthermore, disposing the other end of the second rotating member 106 within the third opening 1051 facilitates the flattening of the second rotating member 106, the second connecting base 105, and the second housing 12, ensuring the distance between the second rotating member 106 and the flexible display screen 2, and preventing the second rotating member 106 from colliding with the flexible display screen 2. The third opening 1051 of the second connecting seat 105 and the first opening 1021 of the first connecting seat 102 are offset in the direction along the central axis M of the rotating shaft mechanism 10, so that the other end of the second rotating member 106 is located in the third opening 1051 and the other end of the first rotating member 103 is located in the first opening 1021.

[0072] Please refer to Figure 23 and Figure 24The other end of the first support member 104 is rotatably connected to the first connecting seat 102 via a circular arc track groove and a circular arc sliding part. The central axis of the circular arc track groove between the other end of the first support member 104 and the first connecting seat 102 is the rotation axis of the first support member 104 relative to the first connecting seat 102. In this embodiment, the rotational connection between the first support member 104 and the first connecting seat 102 is achieved through the cooperation of the circular arc track groove and the circular arc sliding part. The design of the circular arc track groove allows the rotation axis of the first support member 104 relative to the first connecting seat 102 to be closer to the theoretically designed position, thus giving the first support member 104 a precise motion trajectory. Furthermore, the rotational connection between the first support member 104 and the first connecting seat 102 via the cooperation of the circular arc track groove and the circular arc sliding part also facilitates further limiting of the first support member 104 through the circular arc track groove and the circular arc sliding part, reducing the need for other limiting structural components. Optionally, the first support member 104 includes an arcuate portion, and the first connecting seat 102 includes an arcuate groove. The first support member 104 and the first connecting seat 102 are rotatably connected through the engagement of the arcuate portion and the arcuate groove. Alternatively, the first support member 104 includes an arcuate groove, and the first connecting seat 102 includes an arcuate portion. The first support member 104 and the first connecting seat 102 are rotatably connected through the engagement of the arcuate portion and the arcuate groove. In the following embodiments, the example is that the first support member 104 includes an arcuate portion, and the first connecting seat 102 includes an arcuate groove.

[0073] In one embodiment, the arcuate portion 1040 of the first support member 104 includes a first arcuate surface 104a and a first limiting surface 104b adjacent to the first arcuate surface 104a. The arcuate groove 1020 of the first connecting seat 102 includes a second arcuate surface 102a and a second limiting surface 102b adjacent to the second arcuate surface 102a. The first arcuate surface 104a and the second arcuate surface 102a are at least partially in contact. The first limiting surface 104b and the second limiting surface 102b are disposed opposite to each other. When the folded housing 1 is in the folded state, the first limiting surface 104b and the second limiting surface 102b abut against each other. When the folded housing 1 is in the folded state, the abutment between the first limiting surface 104b and the second limiting surface 102b can limit the tilt angle of the first support member 104, and prevent the tilt angle of the first support member 104 from being too large, thus pulling the flexible display screen 2.

[0074] Please refer to Figure 23 and Figure 24The other end of the second support member 107 is rotatably connected to the second connecting seat 105 via a circular arc track groove and a circular arc sliding part. The central axis of the circular arc track groove between the other end of the second support member 107 and the second connecting seat 105 is the rotation axis of the second support member 107 relative to the second connecting seat 105. In this embodiment, the rotational connection between the second support member 107 and the second connecting seat 105 is achieved through the cooperation of the circular arc track groove and the circular arc sliding part. The design of the circular arc track groove allows the rotation axis of the second support member 107 relative to the second connecting seat 105 to be closer to the theoretically designed position, thus giving the second connecting seat 105 a precise motion trajectory. Furthermore, the rotational connection between the second support member 107 and the second connecting seat 105 via the cooperation of the circular arc track groove and the circular arc sliding part also facilitates further limiting of the second support member 107 through the circular arc track groove and the circular arc sliding part, reducing the need for other limiting structural components. Optionally, the second support member 107 includes an arcuate portion, and the second connecting seat 105 includes an arcuate groove. The second support member 107 and the second connecting seat 105 are rotatably connected through the engagement of the arcuate portion and the arcuate groove. Alternatively, the second support member 107 includes an arcuate groove, and the second connecting seat 105 includes an arcuate portion. The second support member 107 and the second connecting seat 105 are rotatably connected through the engagement of the arcuate portion and the arcuate groove. In the following embodiments, the second support member 107 includes an arcuate portion, and the second connecting seat 105 includes an arcuate groove as an example.

[0075] In one embodiment, the arcuate portion 1070 of the second support member 107 includes a third arcuate surface 107a and a third limiting surface 107b adjacent to the third arcuate surface 107a. The arcuate groove 1050 of the second connecting seat 105 includes a fourth arcuate surface 105a and a fourth limiting surface 105b adjacent to the fourth arcuate surface 105a. The third arcuate surface 107a and the fourth arcuate surface 105a are at least partially in contact. The third limiting surface 107b and the fourth limiting surface 105b are disposed opposite to each other. When the folded housing 1 is in the folded state, the third limiting surface 107b and the fourth limiting surface 105b abut against each other. When the folded housing 1 is in the folded state, the abutment between the third limiting surface 107b and the fourth limiting surface 105b can limit the tilt angle of the second support member 107, and prevent the tilt angle of the second support member 107 from being too large, thus pulling the flexible display screen 2.

[0076] Further, please refer to Figure 25 and Figure 26The rotating mechanism 10 also includes a decorative element 13, and the base 101 is housed within the decorative element 13. The decorative element 13 and the base 101 can be fixedly connected. For example, the fixed connection methods between the decorative element 13 and the base 101 include, but are not limited to, integral connection, threaded connection, snap-fit, welding, riveting, and bonding. In this embodiment, the decorative element 13 is semi-circular. In the first position, the first rotating element 103 is supported on the decorative element 13. In other words, when the folded housing 1 is in a flattened state, the first rotating element 103 abuts against the side of the decorative element 13 facing the first sub-bending area 201 of the flexible display screen 2. By providing the decorative element 13, the base 101 can be housed, which has a decorative effect on the appearance of the folded housing 1 when it is in a folded state; when the folded housing 1 is in a flattened state, the first rotating element 103 is supported on the decorative element 13, which can prevent the first rotating element 103 from bending in the opposite direction. When the folding housing 1 is in a flattened state, the second rotating member 106 is also supported on the decorative member 13. In other words, when the folding housing 1 is in a flattened state, the second rotating member 106 abuts against the side of the decorative member 13 facing the third sub-bending area 203 of the flexible display screen 2. When the folding housing 1 is in a flattened state, the second rotating member 106 is supported on the decorative member 13, which can prevent the second rotating member 106 from bending in the opposite direction and better achieve the flattening of the first rotating member 103 and the second rotating member 106.

[0077] Further, please refer to Figures 26 to 29 The rotating shaft mechanism 10 also includes a first driving member 108. The first driving member 108 is located between the base 101 and the first support member 104. One end of the first driving member 108 is located on the base 101. One end of the first driving member 108 is rotatably connected to the base 101. The other end of the first driving member 108 is located on the side of the first support member 104 facing the first connecting seat 102. The other end of the first driving member 108 is rotatably connected to one end of the first support member 104. The first driving member 108 and the base 101 can be directly rotatably connected through a shaft and hole fit, an arc-shaped groove and an arc-shaped sliding part fit, or a rotatable connection can be formed through other shaft components such as a pin. The first driving member 108 and the first support member 104 can be directly rotatably connected through a shaft and hole fit, an arc-shaped groove and an arc-shaped sliding part fit, or a rotatable connection can be formed through other shaft components such as a pin.

[0078] The rotating shaft mechanism 10 also includes a second driving member 109. The second driving member 109 is located between the base 101 and the second support member 107. One end of the second driving member 109 is located on the base 101 and rotatably connected to it. The other end of the second driving member 109 is located on the side of the second support member 107 facing the second connecting seat 105. The other end of the second driving member 109 is rotatably connected to one end of the second support member 107. The second driving member 109 and the base 101 can be directly rotatably connected via a shaft and hole fit, an arc-shaped groove and an arc-shaped sliding part fit, or a rotatable connection via a pin or other shaft-like components. The second driving member 109 and the second support member 107 can be directly rotatably connected via a shaft and hole fit, an arc-shaped groove and an arc-shaped sliding part fit, or a rotatable connection via a pin or other shaft-like components.

[0079] The second driving member 109 and the first driving member 108 can be symmetrical or asymmetrical along the central axis M of the rotating shaft mechanism 10. In this embodiment, the second driving member 109 and the first driving member 108 are offset in the direction along the central axis M of the rotating shaft mechanism 10 to distribute the force on the rotating shaft mechanism 10 and reduce the radial dimension of the rotating shaft mechanism 10. Optionally, the first rotating member 103, the second rotating member 106, the first driving member 108, and the second driving member 109 are arranged sequentially along the central axis M of the rotating shaft mechanism 10; or, the first rotating member 103, the first driving member 108, the second rotating member 106, and the second driving member 109 are arranged sequentially along the central axis M of the rotating shaft mechanism 10.

[0080] In one embodiment, please refer to Figure 29 and Figure 30 The other end of the first driving member 108 is rotatably connected to one end of the first support member 104. The other end of the second driving member 109 is rotatably connected to one end of the second support member 107. By rotatably connecting the other end of the first driving member 108 to one end of the first support member 104 and the other end of the second driving member 109 to one end of the second support member 107, the structure of the rotating shaft mechanism 10 can be simplified and the design difficulty of the rotating shaft mechanism 10 can be reduced.

[0081] Optionally, the rotating shaft mechanism 10 further includes a rotating shaft. The other end of the first driving member 108 is rotatably connected to one end of the first support member 104 via a rotating shaft and a shaft hole. The rotating shaft is located in one of the first driving member 108 and the first support member 104, and the shaft hole is located in the other of the first driving member 108 and the first support member 104. The other end of the second driving member 109 is rotatably connected to one end of the second support member 107 via a rotating shaft and a shaft hole. The rotating shaft is located in one of the second driving member 109 and the second support member 107, and the shaft hole is located in the other of the second driving member 109 and the second support member 107. In one embodiment, the rotating shaft mechanism 10 includes a first rotating shaft 14 and a second rotating shaft 15. The other end of the first driving member 108 has a first shaft hole 1080, and one end of the first support member 104 has a second shaft hole 1041. One end of the first rotating shaft 14 passes through the first shaft hole 1080, and the other end of the first rotating shaft 14 passes through the second shaft hole 1041, so that the first driving member 108 and the first support member 104 are rotatably connected. The other end of the second driving member 109 is provided with a third shaft hole 1090, and one end of the second support member 107 is provided with a fourth shaft hole 1071. One end of the second rotating shaft 15 passes through the third shaft hole 1090, and the other end of the second rotating shaft 15 passes through the fourth shaft hole 1071, so that the second driving member 109 and the second support member 107 are rotatably connected. The first driving member 108 and the first support member 104 are rotatably connected by the first rotating shaft 14, and the second driving member 109 and the second support member 107 are rotatably connected by the second rotating shaft 15. Since the size of the first rotating shaft 14 and the second rotating shaft 15 is small, the size of the rotating shaft mechanism 10 can be reduced, which is conducive to the miniaturization of the folding housing 1 and the electronic device 100.

[0082] One end of the first driving member 108 is rotatably connected to the base 101 via a circular arc track groove and a circular arc sliding part. The central axis of the circular arc track groove between the first driving member 108 and the base 101 is the rotation axis of the first driving member 108 around the base 101. In this embodiment, the rotational connection between the first driving member 108 and the base 101 is achieved through the cooperation of the circular arc track groove and the circular arc sliding part. The design of the circular arc track groove allows the rotation axis of the first driving member 108 to be closer to the theoretically designed position, thus giving the first driving member 108 a precise motion trajectory. Furthermore, the rotational connection between the first driving member 108 and the base 101 achieved through the cooperation of the circular arc track groove and the circular arc sliding part also prevents the first driving member 108 from piercing or damaging the flexible display screen 2 when its rotation axis approaches the flexible display screen 2. Optionally, the first driving member 108 includes an arcuate portion, and the base 101 includes an arcuate groove. The first driving member 108 and the base 101 are rotatably connected through the engagement of the arcuate portion and the arcuate groove. Since the base 101 has a relatively large dimension along the thickness direction of the folded shell 1, it is easier to machine the arcuate groove on the base 101. The first driving member 108 can be selected as a driving arm or driving rod, which has a smaller dimension and is more convenient to form the arcuate portion. Of course, in other embodiments, an arcuate groove can be provided in the first driving member 108, and an arcuate portion can be provided in the base 101 to achieve a rotatable connection between the first driving member 108 and the base 101.

[0083] One of the base 101 and the first driving member 108 further includes a second arcuate groove, a third arcuate block and a fourth arcuate block disposed within the second arcuate groove, the third arcuate block and the fourth arcuate block being disposed opposite to each other; the other of the base 101 and the first driving member 108 includes a second arcuate portion, a third trajectory groove and a fourth trajectory groove disposed on the second arcuate portion, the third trajectory groove and the fourth trajectory groove being disposed opposite to each other, the second arcuate portion sliding within the second arcuate groove, the third arcuate block sliding within the third trajectory groove, and the fourth arcuate block sliding within the fourth trajectory groove. In one embodiment, as... Figure 31As shown, the base 101 also has a second arcuate groove 1013, a third arcuate block 101e, and a fourth arcuate block 101f disposed within the second arcuate groove 1013. The third arcuate block 101e and the fourth arcuate block 101f are arranged opposite to each other. For example, the third arcuate block 101e and the fourth arcuate block 101f are arranged opposite to each other along the direction of the central axis M of the rotating shaft mechanism 10. The first driving member 108 includes a second arcuate portion 1081, a third track groove 1082, and a fourth track groove 1083 disposed on the second arcuate portion 1081. The third track groove 1082 and the fourth track groove 1083 are arranged opposite to each other. For example, the third track groove 1082 and the fourth track groove 1083 are arranged opposite to each other along the direction of the central axis M of the rotating shaft mechanism 10. Optionally, both the third track groove 1082 and the fourth track groove 1083 are arcuate track grooves. The second arc portion 1081 slides within the second arc groove 1013, the third arc block 101e slides within the third track groove 1082, and the fourth arc block 101f slides within the fourth track groove 1083. In this embodiment, by setting opposing third arc blocks 101e and fourth arc blocks 101f in the second arc groove 1013 of the base 101, and setting opposing third track grooves 1082 and fourth track grooves 1083 in the second arc portion 1081 of the first drive member 108, the second arc portion 1081 slides in the second arc groove 1013, the third arc block 101e slides in the third track groove 1082, and the fourth arc block 101f slides in the fourth track groove 1083. While realizing the rotational connection between the first drive member 108 and the base 101, the opposing third arc blocks 101e and fourth arc blocks 101f and the opposing third track grooves 1082 and fourth track grooves 1083 form a further cooperation, which can reduce the cooperation gap and assembly error between the first drive member 108 and the base 101. In addition, a constraint is formed during the rotation of the first drive member 108 relative to the base 101, which can control the movement accuracy of the first drive member 108. Of course, in other embodiments, only one of the third arc block 101e and the fourth arc block 101f may be provided in the second arc groove 1013 of the base 101, and one of the third track groove 1082 and the fourth track groove 1083 may be provided on the second arc portion 1081 of the first drive member 108, so that the third arc block 101e slides in the third track groove 1082 or the fourth arc block 101f slides in the fourth track groove 1083, thereby realizing the assembly control of the first drive member 108 and the base 101 and the motion control of the first drive member 108.In other embodiments, the groove wall of the second arc groove 1013 of the base 101 can form at least one trajectory groove, and at least one arc block can be formed on the second arc portion 1081 of the first drive member 108, so that the second arc groove 1013 and the second arc portion 1081 cooperate, and at the same time, the arc block on the second arc portion 1081 cooperates with the trajectory groove of the second arc groove 1013, thereby realizing the assembly control of the first drive member 108 and the base 101 and the motion control of the first drive member 108.

[0084] One end of the second driving member 109 is rotatably connected to the base 101 via a circular arc track groove and a circular arc sliding part. The central axis of the circular arc track groove between the second driving member 109 and the base 101 is the rotation axis of the second driving member 109 around the base 101. In this embodiment, the rotational connection between the second driving member 109 and the base 101 is achieved through the cooperation of the circular arc track groove and the circular arc sliding part. The design of the circular arc track groove allows the rotation axis of the second driving member 109 to be closer to the theoretically designed position, thus giving the second driving member 109 a precise motion trajectory. Furthermore, the rotational connection between the second driving member 109 and the base 101 via the cooperation of the circular arc track groove and the circular arc sliding part also prevents the second driving member 109 from piercing or damaging the flexible display screen 2 when its rotation axis approaches the flexible display screen 2. Optionally, the second driving member 109 includes an arcuate portion, and the base 101 includes an arcuate groove. The second driving member 109 and the base 101 are rotatably connected through the engagement of the arcuate portion and the arcuate groove. Since the base 101 has a relatively large dimension along the thickness direction of the folded shell 1, it is easier to machine the arcuate groove on the base 101. The second driving member 109 can be selected as a rotating arm or rotating rod, which has a smaller dimension and is more convenient to form the arcuate portion. Of course, in other embodiments, an arcuate groove can be provided in the second driving member 109, and an arcuate portion can be provided in the base 101 to achieve a rotatable connection between the second driving member 109 and the base 101.

[0085] One of the base 101 and the second driving member 109 further includes a fourth arcuate groove, a seventh arcuate block and an eighth arcuate block disposed within the fourth arcuate groove, the seventh arcuate block and the eighth arcuate block being disposed opposite to each other; the other of the base 101 and the second driving member 109 includes a fourth arcuate portion, a seventh trajectory groove and an eighth trajectory groove disposed on the fourth arcuate portion, the seventh trajectory groove and the eighth trajectory groove being disposed opposite to each other, the fourth arcuate portion sliding within the fourth arcuate groove, the seventh arcuate block sliding within the seventh trajectory groove, and the eighth arcuate block sliding within the eighth trajectory groove. In one embodiment, as... Figure 31As shown, the base 101 also has a fourth arcuate groove 1014, a seventh arcuate block 101g, and an eighth arcuate block 101h disposed within the fourth arcuate groove 1014. The seventh arcuate block 101g and the eighth arcuate block 101h are arranged opposite to each other. For example, the seventh arcuate block 101g and the eighth arcuate block 101h are arranged opposite to each other along the direction of the central axis M of the rotating shaft mechanism 10. The second driving member 109 includes a fourth arcuate portion 1091, a seventh track groove 1092, and an eighth track groove 1093 disposed on the fourth arcuate portion 1091. The seventh track groove 1092 and the eighth track groove 1093 are arranged opposite to each other. For example, the seventh track groove 1092 and the eighth track groove 1093 are arranged opposite to each other along the direction of the central axis M of the rotating shaft mechanism 10. Optionally, both the seventh track groove 1092 and the eighth track groove 1093 are arcuate track grooves. The fourth arc portion 1091 slides within the fourth arc groove 1014, the seventh arc block 101g slides within the seventh track groove 1092, and the eighth arc block 101h slides within the eighth track groove 1093. In this embodiment, by providing opposing seventh arc blocks 101g and seventh arc blocks 101h in the fourth arc groove 1014 of the base 101, and providing opposing seventh track grooves 1092 and eighth track grooves 1093 in the fourth arc portion 1091 of the second drive member 109, the fourth arc portion 1091 slides in the fourth arc groove 1014, the seventh arc block 101g slides in the seventh track groove 1092, and the eighth arc block 101h slides in the eighth track groove 1093. While realizing the rotational connection between the second drive member 109 and the base 101, the opposing seventh arc blocks 101g and eighth arc blocks 101h form a further cooperation with the opposing seventh track grooves 1092 and eighth track grooves 1093, which can reduce the cooperation gap and assembly error between the second drive member 109 and the base 101. Furthermore, the constraint formed during the rotation of the second drive member 109 relative to the base 101 can control the movement accuracy of the second drive member 109. Of course, in other embodiments, only one of the seventh arc block 101g and the eighth arc block 101h may be provided in the fourth arc groove 1014 of the base 101, and one of the seventh track groove 1092 and the eighth track groove 1093 may be provided on the fourth arc portion 1091 of the second drive member 109, so that the seventh arc block 101g slides in the seventh track groove 1092 or the eighth arc block 101h slides in the eighth track groove 1093, thereby realizing the assembly control of the second drive member 109 and the base 101 and the motion control of the second drive member 109.In other embodiments, the groove wall of the fourth arc groove 1014 of the base 101 can form at least one trajectory groove, and at least one arc block can be formed on the third arc portion 1060 of the second drive member 109, so that the fourth arc groove 1014 and the fourth arc portion 1091 cooperate, and at the same time, the arc block on the fourth arc portion 1091 cooperates with the trajectory groove of the fourth arc groove 1014, thereby realizing the assembly control of the second drive member 109 and the base 101 and the motion control of the second drive member 109.

[0086] Specifically, the first rotation axis of the first support member 104 relative to the first connecting seat 102 is parallel to and not collinear with the first rotation axis of the first support member 104 relative to the first driving member 108. In other words, the central axis of the second arc surface 102a is parallel to and not collinear with the central axis of the first rotating shaft 14. Similarly, the third rotation axis of the second support member 107 relative to the second connecting seat 105 is parallel to and not collinear with the fourth rotation axis of the second support member 107 relative to the second driving member 109. In other words, the central axis of the fourth arc surface 105a is parallel to and not collinear with the central axis of the second rotating shaft 15. "Not collinear" means misaligned.

[0087] In this embodiment, the first support member 104 is flattened and tilted under the action of the first connecting seat 102 and the first driving member 108; the second support member 107 is flattened and tilted under the action of the second connecting seat 105 and the second driving member 109. In one application scenario, when the first housing 11 is bent from a flattened state to a folded state under the action of an external force, the first connecting seat 102 and the first rotating member 103 rotate with the rotation of the first housing 11. During the rotation of the first housing 11, the first connecting seat 102 transmits motion and power to the first support member 104, and then to the first driving member 108 through the first support member 104. Since the first driving member 108 drives the first support member 104 to rotate around the central axis of the first rotating shaft 14, and the first housing 11 drives the first support member 104 to rotate around the central axis of the second arc surface 102a, and the central axis of the second arc surface 102a is parallel to and not collinear with the central axis of the first rotating shaft 14, under the action of the first housing 11 and the first driving member 108, the first support member 104 gradually tilts relative to the first connecting seat 102, and the end closer to the base 101 tilts towards the side closer to the first connecting seat 102, and the end away from the base 101 tilts towards the side away from the first connecting seat 102. When the second housing 12 is bent from a flattened state to a folded state under the action of external force, the second connecting seat 105 and the second rotating member 106 rotate with the rotation of the second housing 12. During the rotation of the second housing 12, the second connecting seat 105 transmits motion and power to the second support member 107, and then to the second driving member 109 through the second support member 107. Since the second driving member 109 drives the second support member 107 to rotate around the central axis of the second rotating shaft 15, and the second housing 12 drives the second support member 107 to rotate around the central axis of the fourth arc surface 105a, and the central axis of the fourth arc surface 105a is parallel to and not collinear with the central axis of the second rotating shaft 15, under the action of the second housing 12 and the second driving member 109, the second support member 107 gradually tilts relative to the second connecting seat 105, and the end closer to the base 101 tilts towards the side closer to the second connecting seat 105, and the end away from the base 101 tilts towards the side away from the second connecting seat 105.

[0088] like Figure 32As shown, the first connecting seat 102 also has a second opening 1022. In one embodiment, the second opening 1022 extends through the first connecting seat 102 along the X-axis. At least one end of the first driving member 108 and at least one end of the first support member 104 are disposed within the second opening 1022. It is understood that the first driving member 108 and the first support member 104 are rotatably connected within the second opening 1022. By disposing the other end of the first driving member 108 and one end of the first support member 104 within the second opening 1022, the space occupied by the first connecting seat 102, the first driving member 108, and the first support member 104 can be reduced, improving the compactness of the rotating shaft mechanism 10. In addition, the other end of the first driving member 108 and one end of the first support member 104 are located in the second opening 1022, which makes it easier for the first driving member 108 to flatten out with the first connecting seat 102 and the first housing 11, ensuring the distance between the first driving member 108 and the flexible display screen 2, and preventing the first driving member 108 from colliding with the flexible display screen 2 during its movement.

[0089] like Figure 33 As shown, the second connecting seat 105 also has a fourth opening 1052. In one embodiment, the fourth opening 1052 extends through the second connecting seat 105 along the X-axis. The other end of the second driving member 109 and one end of the second support member 107 are located within the second opening 1022. It is understood that the second driving member 109 and the second support member 107 are rotatably connected within the second opening 1022. By placing the other end of the second driving member 109 and one end of the second support member 107 within the second opening 1022, the space occupied by the second connecting seat 105, the second driving member 109, and the first support member 104 can be reduced, improving the compactness of the rotating shaft mechanism 10. Furthermore, placing the other end of the second driving member 109 and one end of the second support member 107 within the second opening 1022 facilitates the flattening of the second driving member 109 with the second connecting seat 105 and the first housing 11, ensuring the distance between the second driving member 109 and the flexible display screen 2, and preventing the second driving member 109 from colliding with the flexible display screen 2 during movement.

[0090] Further, please refer to Figure 34 and Figure 35The rotating mechanism 10 also includes a lifting assembly. The lifting assembly includes a lifting plate 16 and a third driving member. The lifting plate 16 covers the base 101. Specifically, the lifting plate 16 is located between the first support member 104 and the second support member 107. The lifting plate 16 can support the second sub-bending area 202 of the flexible display screen 2 when the electronic device 100 is in a flattened state, so as to improve the force on the second sub-bending area 202; at the same time, it can support the middle area of ​​the second sub-bending area 202 of the flexible display screen 2 when the electronic device 100 is in a folded state, so as to support the second sub-bending area 202 to maintain a free bending state. The third driving member is connected to the lifting plate 16 and is used to drive the lifting plate 16 closer to or away from the base 101. In one embodiment, the third driving member includes the aforementioned first rotating member 103, second rotating member 106, and at least one elastic member disposed between the lifting plate 16 and the base 101. When the folded housing 1 is in the flattened state, the first rotating member 103 and the second rotating member 106 abut against the side of the lifting plate 16 facing the base 101. The two ends of the elastic member are fixedly connected to the lifting plate 16 and the base 101, respectively. During the process of the folded housing 1 from the folded state to the flattened state, one end of the first rotating member 103 and one end of the second rotating member 106 extend between the lifting plate 16 and the base 101, and push the lifting plate 16 up to gradually move away from the base 101, thereby supporting the second sub-bending area 202 of the flexible display screen 2 when the folded housing 1 is in the flattened state. During the process of the folded housing 1 changing from a flattened state to a folded state, the first rotating member 103 and the second rotating member 106 gradually move away from the lifting plate 16. The elastic member drives the lifting plate 16 to descend, gradually approaching the base 101. Thus, when the folded housing 1 is in the folded state, it descends to a position that can support the middle area of ​​the second sub-bending area 202 of the flexible display screen 2. Furthermore, during the process of the folded housing 1 changing from a flattened state to a folded state, the free bending of the second sub-bending area 202 of the flexible display screen 2 is not affected. The elastic member can be a spring, a spiral column, etc. There can be one or more elastic members. Of course, in other embodiments, the third driving member can include a motor and a conversion structure connected between the motor and the lifting plate 16. The conversion structure is used to convert the rotation of the motor shaft into the lifting motion of the lifting plate 16. By setting the lifting plate 16, the second sub-bending area 202 of the flexible display screen 2 can be supported when the folded shell 1 is in the flat state, thereby improving the stress on the second sub-bending area 202; when the folded shell 1 is in the folded state, the middle area supporting the second sub-bending area 202 of the flexible display screen 2 helps to make the second sub-bending area 202 arc-shaped.
