Description

Technical Field

[0001] This application relates to the field of electronic technology, specifically to a hinge assembly, a foldable housing device, and a foldable electronic device. Background Technology

[0002] The hinge, as the structure enabling foldability, determines the folding performance of foldable electronic devices. In related technologies, the space utilization of the hinge is not high, especially in the thickness direction, where the hinge is generally quite thick. Summary of the Invention

[0003] This application provides a hinge assembly, a foldable housing device, and a foldable electronic device that facilitate thickness reduction while achieving back-side shielding.

[0004] On one hand, this application provides a pivot assembly, including:

[0005] Fixed structure;

[0006] A first rotating shaft mechanism is disposed on one side of the fixed structure. The first rotating shaft mechanism includes a first rotating member and at least one second rotating member. The first rotating member is rotatably connected to the fixed structure, and the second rotating member is rotatably connected to the fixed structure.

[0007] The first covering member includes a first covering portion and a first clearance portion. The first covering portion covers the back side of the first rotating member and / or the second rotating member. The first clearance portion is connected to the side of the first covering portion near the fixed structure. At least a portion of the first clearance portion is bent relative to the first covering portion and forms a first clearance space at the rotational connection between the first rotating shaft mechanism and the fixed structure.

[0008] On the other hand, this application also provides a foldable housing device, including a first housing assembly, a second housing assembly and the aforementioned pivot assembly, wherein the first housing assembly and the second housing assembly are disposed on opposite sides of the pivot assembly and connected to the pivot assembly.

[0009] In another aspect, this application also provides a foldable electronic device, including a flexible display screen and the aforementioned foldable housing device, wherein the flexible display screen is supported on the foldable housing device, and at least a portion of the flexible display screen folds outward during the process of the foldable electronic device switching from a flattened state to a folded state.

[0010] The pivot assembly provided in this application includes a fixed structure, a first pivot mechanism, and a first cover. The first pivot mechanism is located on one side of the fixed structure and includes a first rotating member and a second rotating member. The first rotating member is rotatably connected to the fixed structure, and the second rotating member is also rotatably connected to the fixed structure. The first cover includes a first covering portion and a first clearance portion. Since the first covering portion covers the back side of the first rotating member and / or the second rotating member, the first cover can shield the first rotating member and / or the second rotating member, preventing the components of the first pivot mechanism from being exposed. Furthermore, since the first clearance portion is bent relative to the first covering portion, a first clearance space is formed at the rotational connection between the first pivot mechanism and the fixed structure. Thus, by designing the structure of the first cover, interference with the rotation of the first rotating member and / or the second rotating member can be avoided. It also facilitates the provision of a certain space for the structure at the rotational connection between the first rotating member and / or the second rotating member and the fixed structure through the first clearance space, thereby improving the space utilization rate of the pivot assembly in the thickness direction and achieving a reduction in the thickness of the pivot assembly.

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.

[0046] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish different objects, not to describe a particular order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, an assembly or device that includes one or more components is not limited to the one or more components listed, but may optionally also include one or more components not listed but inherent to the exemplified product, or one or more components that it should have based on the described function.

[0047] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the foldable electronic device 1000 provided in this application embodiment when it is in a flattened state. Figure 2 for Figure 1 The diagram shows a structural illustration of the foldable electronic device 1000 in its folded state. Figure 3 for Figure 1 The diagram shows another structural schematic of the foldable electronic device 1000 in its folded state. The foldable electronic device 1000 can be a foldable phone, foldable tablet, or other device with foldable functionality. In this embodiment, a foldable phone is used as an example. The foldable electronic device 1000 has a flattened state and a folded state. Of course, the foldable electronic device 1000 can also have one or more hovering states at different angles. Please refer to the following examples in this embodiment. Figure 1 and Figure 2 The foldable electronic device 1000 can be a foldable electronic device that folds outwards (half-fold), or, please refer to... Figure 1 and Figure 3 The folding method of the foldable electronic device 1000 can include outward folding. For example, the foldable electronic device 1000 can be an S-shaped three-fold foldable electronic device, in which case the folding method of the foldable electronic device 1000 includes outward folding and inward folding.

[0048] The foldable electronic device 1000 includes a flexible display screen 200 and a foldable housing device 100. When the foldable electronic device 1000 is in a flattened state, both the flexible display screen 200 and the foldable housing device 100 are flattened; when the foldable electronic device 1000 is in a folded state, both the flexible display screen 200 and the foldable housing device 100 are folded. It is understood that the flexible display screen 200 and the foldable housing device 100 unfold and fold synchronously. The unfolding described in this embodiment refers to the process of switching from a folded state to a flattened state, and the folding refers to the process of switching from a flattened state to a folded state. The flexible display screen 200 is supported on the foldable housing device 100. Part of the flexible display screen 200 can be fixedly connected to the foldable housing device 100 to allow it to bend under the influence of the foldable housing device 100, while another part of the flexible display screen 200 can be unconnected to the foldable housing device 100 to allow it to bend freely. During the transition of the foldable electronic device 1000 from a flattened state to a folded state, at least a portion of the flexible display screen 200 folds outward. In other words, when the foldable electronic device 1000 is in the folded state, at least a portion of the flexible display screen 200 is located on the outside of the foldable housing device 100.

[0049] Flexible display screen 200 includes, but is not limited to, organic light-emitting diode (OLED) type flexible display screen.

[0050] In one possible embodiment, please refer to Figure 4 and Figure 5 , Figure 4 for Figure 1 The diagram shows a structural schematic of the flexible display screen 200 in the foldable electronic device 1000 when it is in a flattened state. Figure 5 for Figure 2The diagram shows the structure of the flexible display screen 200 in the foldable electronic device 1000 when it is in a folded state. In this embodiment, during the process of switching the foldable electronic device 1000 from a flattened state to a folded state, the entire flexible display screen 200 folds outward. Specifically, the flexible display screen 200 includes a first non-bending display portion 21, a bending display portion 22, and a second non-bending display portion 23 arranged sequentially. When the flexible display screen 200 is in a flattened state, the first non-bending display portion 21, the bending display portion 22, and the second non-bending display portion 23 are arranged sequentially and are all flattened, with the angle between the first non-bending display portion 21 and the second non-bending display portion 23 being 180° or close to 180°. During the process of switching the flexible display screen 200 from a flattened state to a folded state, the bending display portion 22 bends, while the first non-bending display portion 21 and the second non-bending display portion 23 do not bend, but the angle between the first non-bending display portion 21 and the second non-bending display portion 23 gradually decreases. When the flexible display screen 200 is in the merged state, the first non-bending display part 21 and the second non-bending display part 23 remain flat, the angle between the first non-bending display part 21 and the second non-bending display part 23 is reduced to 0° or close to 0°, and the bending display part 22 is bent into a certain shape, such as: U-shape, teardrop shape, V-shape, etc.

[0051] The bending display unit 22 includes a first sub-bending display unit 22a, a second sub-bending display unit 22b, and a third sub-bending display unit 22c arranged sequentially. The first sub-bending display unit 22a is adjacent to the first non-bending display unit 21, and the third sub-bending display unit 22c is adjacent to the second non-bending display unit 23. It is understood that the first non-bending display unit 21, the first sub-bending display unit 22a, the second sub-bending display unit 22b, the third sub-bending display unit 22c, and the second non-bending display unit 23 are arranged sequentially. When the flexible display screen 200 is in the merged state, the first non-bending display section 21 is opposite to the second non-bending display section 23, and the first sub-bending display section 22a is opposite to the third sub-bending display section 22c. The line length between the end of the first sub-bending display section 22a away from the second sub-bending display section 22b and the end of the third sub-bending display section 22c away from the second sub-bending display section 22b is L1, and the line length between the end of the first sub-bending display section 22a close to the second sub-bending display section 22b and the end of the third sub-bending display section 22c close to the second sub-bending display section 22b is L2. In the merged state, the U-shaped bending of the bending display section 22 means that the line dimension L1 between the end of the first sub-bent bending display section 22a away from the second sub-bent bending display section 22b and the end of the third sub-bent bending display section 22c away from the second sub-bent bending display section 22b is equal to the line dimension L2 between the end of the first sub-bent bending display section 22a near the second sub-bent bending display section 22b and the end of the third sub-bent bending display section 22c near the second sub-bent bending display section 22b. In the merged state, the teardrop-shaped bending of the bending display section 22 means that the line dimension L1 between the end of the first sub-bent bending display section 22a away from the second sub-bent bending display section 22b and the end of the third sub-bent bending display section 22c away from the second sub-bent bending display section 22b is less than the line dimension L2 between the end of the first sub-bent bending display section 22a near the second sub-bent bending display section 22b and the end of the third sub-bent bending display section 22c near the second sub-bent bending display section 22b. In the merged state, the bending display section 22 is bent into a V-shape because the line length L1 between the end of the first sub-bent bending display section 22a away from the second sub-bent bending display section 22b and the end of the third sub-bent bending display section 22c away from the second sub-bent bending display section 22b is greater than the line length L2 between the end of the first sub-bent bending display section 22a near the second sub-bent bending display section 22b and the end of the third sub-bent bending display section 22c near the second sub-bent bending display section 22b. In this embodiment, the bending display section 22 is bent into a U-shape in the merged state as an example.

[0052] In another possible embodiment, please refer to Figure 6 and Figure 7 , Figure 6 for Figure 1 The diagram shows another structural configuration of the flexible display screen 200 in the foldable electronic device 1000 when it is in a flattened state. Figure 7 for Figure 3 This is a schematic diagram of the flexible display screen 200 in the foldable electronic device 1000 when it is in a folded state. In this embodiment, during the process of switching the foldable electronic device 1000 from a flattened state to a folded state, part of the flexible display screen 200 folds outward. Specifically, the flexible display screen 200 includes a first non-bending display section 21, a first bending display section 24, a second non-bending display section 23, a second bending display section 25, and a third non-bending display section 26 arranged sequentially. When the flexible display screen 200 is in a flattened state, the first non-bending display section 21, the first bending display section 24, the second non-bending display section 23, the second bending display section 25, and the third non-bending display section 26 are arranged sequentially and are all flattened. The angle between the first non-bending display section 21 and the second non-bending display section 23 is 180° or close to 180°, and the angle between the second non-bending display section 23 and the third non-bending display section 26 is 180° or close to 180°. During the process of the flexible display screen 200 switching from a flattened state to a merged state, the first bent display section 24 and the second bent display section 25 bend, while the first non-bending display section 21, the second non-bending display section 23 and the third non-bending display section 26 do not bend. However, the angle between the first non-bending display section 21 and the second non-bending display section 23 gradually decreases, and the angle between the second non-bending display section 23 and the third non-bending display section 26 gradually decreases. When the flexible display screen 200 is in the merged state, the first non-bending display portion 21, the second non-bending display portion 23, and the third non-bending display portion 26 remain flat. The angle between the first non-bending display portion 21 and the second non-bending display portion 23 is reduced to 0° or close to 0°, and the angle between the second non-bending display portion 23 and the third non-bending display portion 26 is reduced to 0° or close to 0°. The first bending display portion 24 is bent into a certain shape, such as a U-shape, a teardrop shape, or a V-shape, and the second bending display portion 25 is bent into a certain shape, such as a U-shape or a teardrop shape. In this embodiment, the meanings of U-shape, teardrop shape, and V-shape are the same as in the above embodiments, and will not be repeated here. In this embodiment, the first non-bending display portion 21, the first bending display portion 24, and the second non-bending display portion 23 of the flexible display screen 200 undergo outward folding during the transition from a flattened state to a merged state, while the second non-bending display portion 23, the second bending display portion 25, and the third non-bending display portion 26 of the flexible display screen 200 undergo inward folding during the transition from a flattened state to a merged state. Optionally, the first bending display portion 24 is bent into a U-shape in the merged state, and the second bending display portion 25 is bent into a teardrop shape in the merged state.

Figure 10 for Figure 1 This is another structural schematic diagram of the foldable housing device 100 in the foldable electronic device 1000 when it is in a flattened state. The foldable housing device 100 includes a first housing assembly 20, a second housing assembly 30, and a hinge assembly 10. The first housing assembly 20 and the second housing assembly 30 are disposed on opposite sides of the hinge assembly 10 and connected to the hinge assembly 10.

[0054] In one possible embodiment, please refer to Figure 8 and Figure 9 The first housing assembly 20 is connected to one side of the pivot assembly 10, and the second housing assembly 30 is connected to the side of the pivot assembly 10 opposite to the first housing assembly 20. When the foldable housing device 100 is in the flattened state, the angle between the first housing assembly 20 and the second housing assembly 30 is 180° or close to 180°. When the foldable housing device 100 is in the folded state, the angle between the first housing assembly 20 and the second housing assembly 30 is 0° or close to 0°.

[0055] Please refer to Figure 4 and Figure 8 The first housing assembly 20 supports the first non-bending display portion 21 of the flexible display screen 200, the pivot assembly 10 supports the bending display portion 22 of the flexible display screen 200, and the second housing assembly 30 supports the second non-bending display portion 23 of the flexible display screen 200. Optionally, the first housing assembly 20 and the first non-bending display portion 21 can be fixedly connected, and the second housing assembly 30 and the second non-bending display portion 23 can be fixedly connected. The fixed connection methods include, but are not limited to, bonding, threaded connection, snap-fit ​​connection, welding, etc. The bending display portion 22 is partially connected to the pivot assembly 10. In this embodiment, the pivot assembly 10 is an outward-folding pivot assembly, that is, the pivot assembly 10 folds outward during the switching between a flattened state and a folded state.

[0056] In another possible embodiment, such as Figure 10As shown, the first housing assembly 20 is connected to one side of the first pivot assembly 10a, the second housing assembly 30 is connected to the side of the first pivot assembly 10a opposite to the first housing assembly 20, the second housing assembly 30 is also connected to one side of the second pivot assembly 10b, and the third housing assembly 40 is connected to the side of the second pivot assembly 10b opposite to the second housing assembly 30. When the foldable housing device 100 is in a flattened state, the angle between the first housing assembly 20 and the second housing assembly 30 is 180° or close to 180°, and the angle between the second housing assembly 30 and the third housing assembly 40 is 180° or close to 180°.

The second bending display portion 25 is partially connected to the second pivot assembly 10b. In this embodiment, the first rotating shaft assembly 10a is an outward-folding rotating shaft assembly, and the second rotating shaft assembly 10b is an inward-folding rotating shaft assembly. That is, the first rotating shaft assembly 10a folds outward during the switching between the flattened and folded states, and the second rotating shaft assembly 10b folds inward during the switching between the flattened and folded states. It can be understood that the first rotating shaft assembly 10a in this embodiment is the rotating shaft assembly 10 described in this application.

[0058] Optional, please refer to Figures 8 to 10The first housing assembly 20 includes a first middle frame 201 and a first battery cover 202.

[0059] Please refer to Figures 11 to 16 , Figure 11 This is a schematic diagram of the structure of the rotating shaft assembly 10 provided in this application embodiment when one side is in a flattened state. Figure 12 for Figure 11 An exploded view of the rotating shaft assembly 10 shown. Figure 13 for Figure 11 The diagram shows a cross-sectional structure of the rotating shaft assembly 10 in a flattened state. Figure 14 for Figure 11 The diagram shows another cross-sectional structure of the rotating shaft assembly 10 in a flattened state. Figure 15 for Figure 11 The diagram shows a cross-sectional structure of the rotating shaft assembly 10 in its combined state. Figure 16 for Figure 11 The diagram shows another cross-sectional structure of the rotating shaft assembly 10 in the combined state. The rotating shaft assembly 10 includes a fixed structure 101, a first rotating shaft mechanism 102, and a first cover 103.

[0060] The fixed structure 101 remains relatively stationary during the switching between the flattened and folded states of the pivot assembly 10. Understandably, the fixed structure 101 does not move during the unfolding and folding of the pivot assembly 10. The fixed structure 101 can be a single piece or a structure composed of multiple components connected by detachable or non-detachable fixed connections.

[0061] The first rotating shaft mechanism 102 is disposed on one side of the fixed structure 101. In this embodiment, the first rotating shaft mechanism 102 is disposed between the fixed structure 101 and the first housing assembly 20. The first housing assembly 20 is rotatably connected to the fixed structure 101 via the first rotating shaft mechanism 102 to achieve rotation relative to the fixed structure 101. During the rotation of the first housing assembly 20, the first non-bending display portion 21 of the flexible display screen 200 is unfolded or folded together.

[0062] The first rotating shaft mechanism 102 includes a first rotating member 120 and at least one second rotating member 121. This application does not specify the number of second rotating members 121. In one possible embodiment, the first rotating shaft mechanism 102 includes one first rotating member 120 and a plurality of second rotating members 121. Embodiments of this application Figure 12 The following example uses three second rotating components 121 (labeled 121a, 121b, and 121c, respectively). The three second rotating components 121 have similar structures. The first rotating component 120 is rotatably connected to the fixed structure 101, and the second rotating components 121 are also rotatably connected to the fixed structure 101. It can be understood that during the switching process between the flattened and folded states of the rotating shaft assembly 10, the first rotating component 120 rotates relative to the fixed structure 101, and the second rotating component 121 rotates relative to the fixed structure 101.

[0063] The rotation axis of the first rotating member 120 relative to the fixed structure 101 can be parallel but not collinear with the rotation axis of the second rotating member 121 relative to the fixed structure 101, or the rotation axis of the first rotating member 120 relative to the fixed structure 101 can be parallel and collinear with the rotation axis of the second rotating member 121 relative to the fixed structure 101. By making the rotation axis of the first rotating member 120 relative to the fixed structure 101 parallel with the rotation axis of the second rotating member 121 relative to the fixed structure 101, the first rotating member 120 and the second rotating member 121 can rotate in the same direction relative to the fixed structure 101.

[0064] The rotational connection between the first rotating member 120 and the fixed structure 101 includes, but is not limited to, a rotational connection through the engagement of an arcuate groove and an arcuate block, or a rotational connection through the engagement of a rotating shaft and a shaft hole. The rotational connection between the second rotating member 121 and the fixed structure 101 includes, but is not limited to, a rotational connection through the engagement of an arcuate groove and an arcuate block, or a rotational connection through the engagement of a rotating shaft and a shaft hole. In one possible embodiment, one of the first rotating member 120 and the second rotating member 121 is rotationally connected to the fixed structure 101 through the engagement of an arcuate groove and an arcuate block, and the other of the first rotating member 120 and the second rotating member 121 is rotationally connected to the fixed structure 101 through the engagement of a rotating shaft and a shaft hole.

[0065] The first covering member 103 includes a first covering portion 130 and a first clearance portion 131. The first covering portion 130 covers the back side of the first rotating member 120 and / or the second rotating member 121. In the following embodiment, the first covering portion 130 covers the bending of the first rotating member 120 and the second rotating member 121 relative to the first covering portion 130, and a first clearance space 133 is formed at the rotational connection between the first rotating shaft mechanism 102 and the fixed structure 101.

[0066] The first cover 103 is disposed between the first rotating shaft mechanism 102 and the first battery cover 202. The first cover portion 130 covering the back sides of the first rotating member 120 and the second rotating member 121 can be understood as the first cover portion 130 covering the side of the first rotating member 120 facing away from the flexible display screen 200, and covering the side of the second rotating member 121 facing away from the flexible display screen 200. In this application, the first clearance portion 131 is closer to the fixed structure 101 than the first cover portion 130, and the first cover portion 130 is closer to the first housing assembly 20 than the first clearance portion 131. The first clearance portion 131 and the first cover portion 130 are integrally connected. The first clearance portion 131 forms a first clearance space 133 at the rotational connection between the first rotating shaft mechanism 102 and the fixed structure 101. This includes the first clearance portion 131 forming a first sub-clearance space 133a at the rotational connection between the first rotating member 120 and the fixed structure 101, and / or the first clearance portion 131 forming a second sub-clearance space 133b at the rotational connection between the second rotating member 121 and the fixed structure 101.

[0067] Please refer to Figure 13 and Figure 15 When the first clearance portion 131 forms a first sub-clearance space 133a at the rotational connection between the first rotating member 120 and the fixed structure 101, the bending of at least a portion of the first clearance portion 131 relative to the first covering portion 130 can be understood as at least a portion of the first clearance portion 131 being connected at one end to the first covering portion 130, and at least a portion of the first clearance portion 131 extending toward the side away from the first rotating member 120. At this time, in the flattened state, the distance between the first clearance portion 131 and the surface of the first rotating member 120 in the thickness direction along the shaft assembly 10 is greater than the distance between the surface of the first covering portion 130 and the surface of the first rotating member 120. The distance between the first clearance portion 131 and the surface of the first rotating member 120 in the thickness direction along the shaft assembly 10 in the flattened state can be referred to the attached diagram. Figure 13 As shown in L3; the distance between the surface where the first covering portion 130 and the first rotating member 120 are located along the thickness direction of the rotating shaft assembly 10 can be referred to in the attached diagram. Figure 13As shown in L4. Optionally, in the flattened state, in the direction from the first covering portion 130 to the fixed structure 101, the distance between the surface where the first clearance portion 131 and the first rotating member 120 are located gradually increases, or first increases and then decreases, in the thickness direction of the rotating shaft assembly 10. This can be achieved by designing the shape of the surface of the first clearance portion 131 facing the first rotating member 120. For example, by making the surface of the first clearance portion 131 facing the first rotating member 120 an inclined surface, the distance between the surface of the first clearance portion 131 and the surface of the first rotating member 120 in the thickness direction along the shaft assembly 10 can gradually increase in the flattened state in the direction from the first covering portion 130 to the fixed structure 101. By making the surface of the first clearance portion 131 facing the first rotating member 120 a concave arc surface, or by making the surface of the first clearance portion 131 facing the first rotating member 120 include two sub-inclined surfaces with opposite slopes, the distance between the surface of the first clearance portion 131 and the surface of the first rotating member 120 in the thickness direction along the shaft assembly 10 can first increase and then decrease in the flattened state in the direction from the first covering portion 130 to the fixed structure 101.

[0068] Please refer to Figure 14 and Figure 16 When the first clearance portion 131 forms a second sub-clearance space 133b at the rotational connection between the second rotating member 121 and the fixed structure 101, the bending of at least a portion of the first clearance portion 131 relative to the first covering portion 130 can be understood as at least a portion of the first clearance portion 131 being connected at one end to the first covering portion 130, and at least a portion of the first clearance portion 131 extending toward the side away from the second rotating member 121. At this time, in the flattened state, the distance between the first clearance portion 131 and the surface of the second rotating member 121 along the thickness direction of the rotating shaft assembly 10 is greater than the distance between the surface of the first covering portion 130 and the surface of the second rotating member 121. The distance between the first clearance portion 131 and the surface of the second rotating member 121 in the flattened state along the thickness direction of the rotating shaft assembly 10 can be referred to the attached diagram. Figure 14 As shown in L5; the distance between the surface where the first covering portion 130 and the second rotating member 121 are located along the thickness direction of the rotating shaft assembly 10 can be referred to in the attached diagram. Figure 14As shown in L6. Optionally, in the flattened state, in the direction from the first covering portion 130 to the fixed structure 101, the distance between the surface where the first clearance portion 131 and the second rotating member 121 are located gradually increases, or first increases and then decreases, along the thickness direction of the rotating shaft assembly 10. This can be achieved by designing the shape of the surface of the first clearance portion 131 facing the second rotating member 121. For example, by making the surface of the first clearance portion 131 facing the second rotating member 121 a slope, the distance between the surfaces of the first clearance portion 131 and the second rotating member 121 in the thickness direction of the rotating shaft assembly 10 can gradually increase in the flattened state in the direction from the first covering portion 130 to the fixed structure 101. By making the surface of the first clearance portion 131 facing the second rotating member 121 a concave arc surface, or by making the surface of the first clearance portion 131 facing the second rotating member 121 include two sub-slopes with opposite slopes, the distance between the surfaces of the first clearance portion 131 and the second rotating member 121 in the thickness direction of the rotating shaft assembly 10 can first increase and then decrease in the flattened state in the direction from the first covering portion 130 to the fixed structure 101.

[0069] When the pivot assembly 10 is in a flattened state, the thickness direction of the pivot assembly 10 can be referenced. Figure 13 and Figure 14 As shown in the Z-axis direction, when the rotating shaft assembly 10 is in the merged state, the thickness direction of the rotating shaft assembly 10 can be referenced. Figure 15 and Figure 16 As shown in the Z-axis direction.

[0070] The rotating shaft assembly 10 provided in this application includes a fixed structure 101, a first rotating shaft mechanism 102, and a first cover 103. The first rotating shaft mechanism 102 is disposed on one side of the fixed structure 101 and includes a first rotating member 120 and a second rotating member 121. The first rotating member 120 is rotatably connected to the fixed structure 101, and the second rotating member 121 is rotatably connected to the fixed structure 101. The first cover 103 includes a first covering portion 130 and a first abutment portion 131. Since the first covering portion 130 covers the back side of the first rotating member 120 and / or the second rotating member 121, the first cover 103 can achieve the purpose of shielding the first rotating member 120 and / or the second rotating member 121, thus avoiding... The components of the first rotating shaft mechanism 102 are not exposed. Since the first clearance part 131 is bent relative to the first covering part 130 and a first clearance space 133 is formed at the rotational connection between the first rotating shaft mechanism 102 and the fixed structure 101, the structure of the first covering part 103 is designed in this way to avoid interference between the first covering part 103 and the rotation of the first rotating part 120 and / or the second rotating part 121. It is also beneficial to make room for the structure at the rotational connection between the first rotating part 120 and / or the second rotating part 121 and the fixed structure 101 through the first clearance space, so as to improve the space utilization rate of the rotating shaft assembly 10 in the thickness direction and achieve the thickness reduction of the rotating shaft assembly 10.

[0071] In other words, by making the first cover 103 include a first cover portion 130 and a first clearance portion 131, with the first clearance portion 131 bent relative to the first cover portion 130, and forming a first clearance space 133 at the rotational connection between the first pivot mechanism 102 and the fixed structure 101, when the first clearance space 133 does not accommodate the components that achieve the rotational connection between the first pivot mechanism 102 and the fixed structure 101, the formation of the first clearance space 133 can prevent the first pivot mechanism 102, the fixed structure 101, and the first cover 103 from rotating or interfering with each other during assembly. When 133 houses the components that are rotatably connected to the first pivot mechanism 102 and the fixed structure 101, the formation of the first clearance space 133 is beneficial to thinning one side of the pivot assembly 10 while meeting the thickness requirements of the first pivot mechanism 102. In addition, when the thickness of the pivot assembly 10 is not reduced, the formation of the first clearance space 133 is also beneficial to increasing the thickness of the first pivot mechanism 102, thereby enhancing the structural strength of the first pivot mechanism 102 and increasing the torque on one side of the pivot assembly 10, so as to achieve a good hovering effect on one side of the pivot assembly 10.

[0072] Further, please refer to Figures 17 to 22 , Figure 17 This is a schematic diagram of the structure of the rotating shaft assembly 10 provided in this application embodiment when both sides are in a flattened state. Figure 18 for Figure 17 An exploded view of the rotating shaft assembly 10 shown. Figure 19 for Figure 17 The diagram shows a cross-sectional structure of the rotating shaft assembly 10 in a flattened state. Figure 20 for Figure 17 The diagram shows another cross-sectional structure of the rotating shaft assembly 10 in a flattened state. Figure 21 for Figure 17 The diagram shows a cross-sectional structure of the rotating shaft assembly 10 in its combined state. Figure 22 for Figure 17 The diagram shows another cross-sectional structure of the rotating shaft assembly 10 in the combined state. The rotating shaft assembly 10 also includes a second rotating shaft mechanism 104 and a third cover member 105.

[0073] The second rotating shaft mechanism 104 is located on the other side of the fixed structure 101. In this embodiment, the second rotating shaft mechanism 104 is located between the fixed structure 101 and the second housing assembly 30, that is, the second rotating shaft mechanism 104 and the first rotating shaft mechanism 102 are respectively located on opposite sides of the fixed structure 101. The second housing assembly 30 is rotatably connected to the fixed structure 101 through the second rotating shaft mechanism 104 to achieve rotation relative to the fixed structure 101. During the rotation of the second housing assembly 30, the second non-bending display portion 23 of the flexible display screen 200 is unfolded or folded together.

[0074] The second rotating shaft mechanism 104 includes a third rotating member 140 and at least one fourth rotating member 141. This application does not specifically limit the number of fourth rotating members 141. In one possible embodiment, the second rotating shaft mechanism 104 may include one third rotating member 140 and multiple fourth rotating members 141. (Examples from this application) Figure 18 Taking three fourth rotating components 141 (labeled 141a, 141b, and 141c respectively) as an example, the three fourth rotating components 141 have similar structures. The number of fourth rotating components 141 can be the same as the number of second rotating components 121, and the structure can be symmetrical. The third rotating component 140 is rotatably connected to the fixed structure 101. The fourth rotating component 141 is rotatably connected to the fixed structure 101. It can be understood that during the switching process between the flattened state and the folded state of the rotating shaft assembly 10, the third rotating component 140 rotates relative to the fixed structure 101, and the fourth rotating component 141 rotates relative to the fixed structure 101.

[0075] The rotation axis of the third rotating member 140 relative to the fixed structure 101 can be parallel but not collinear with the rotation axis of the fourth rotating member 141 relative to the fixed structure 101, or the rotation axis of the third rotating member 140 relative to the fixed structure 101 can be parallel and collinear with the rotation axis of the fourth rotating member 141 relative to the fixed structure 101. By making the rotation axis of the third rotating member 140 relative to the fixed structure 101 parallel with the rotation axis of the fourth rotating member 141 relative to the fixed structure 101, the third rotating member 140 and the fourth rotating member 141 can rotate in the same direction relative to the fixed structure 101.

[0076] The rotational connection between the third rotating member 140 and the fixed structure 101 includes, but is not limited to, a rotational connection through the engagement of an arcuate groove and an arcuate block, or a rotational connection through the engagement of a rotating shaft and a shaft hole. The rotational connection between the fourth rotating member 141 and the fixed structure 101 includes, but is not limited to, a rotational connection through the engagement of an arcuate groove and an arcuate block, or a rotational connection through the engagement of a rotating shaft and a shaft hole. In one possible embodiment, one of the third rotating member 140 and the fourth rotating member 141 is rotationally connected to the fixed structure 101 through the engagement of an arcuate groove and an arcuate block, and the other of the third rotating member 140 and the fourth rotating member 141 is rotationally connected to the fixed structure 101 through the engagement of a rotating shaft and a shaft hole.

[0077] The third cover member 105 includes a second cover portion 150 and a second clearance portion 151. The second cover portion 150 covers the back side of the third rotating member 140 and / or the fourth rotating member 141. In the following embodiment, the second cover portion 150 covers the back side of both the third rotating member 140 and the fourth rotating member 141. The second clearance portion 151 is connected to the side of the second cover portion 150 near the fixed structure 101. At least a portion of the second clearance portion 151 is bent relative to the second cover portion 150, forming a second clearance space 153 at the rotational connection between the second rotating shaft mechanism 104 and the fixed structure 101.

[0078] The third cover 105 is disposed between the second rotating shaft mechanism 104 and the second battery cover 302. The second cover portion 150 covering the back sides of the third rotating member 140 and the fourth rotating member 141 can be understood as covering the side of the third rotating member 140 away from the flexible display screen 200, and covering the side of the fourth rotating member 141 away from the flexible display screen 200. In this application, the second clearance portion 151 is closer to the fixed structure 101 than the second cover portion 150, and the second cover portion 150 is closer to the second housing assembly 30 than the second clearance portion 151. The second clearance portion 151 and the second cover portion 150 are integrally connected. The second clearance portion 151 forms a second clearance space 153 at the rotational connection between the second rotating shaft mechanism 104 and the fixed structure 101. This includes the second clearance portion 151 forming a third sub-clearance space 153a at the rotational connection between the third rotating member 140 and the fixed structure 101 and / or the second clearance portion 151 forming a fourth sub-clearance space 153b at the rotational connection between the fourth rotating member 141 and the fixed structure 101.

[0079] Please refer to Figure 19 and Figure 21 When the second clearance portion 151 forms a third sub-clearance space 153a at the rotational connection between the third rotating member 140 and the fixed structure 101, the bending of at least a portion of the second clearance portion 151 relative to the second covering portion 150 can be understood as at least a portion of the second clearance portion 151 being connected at one end to the second covering portion 150, and the other end of at least a portion of the second clearance portion 151 extending toward the side away from the third rotating member 140. At this time, in the flattened state, the distance between the second clearance portion 151 and the surface where the third rotating member 140 is located in the thickness direction along the shaft assembly 10 is greater than the distance between the surface where the second covering portion 150 and the third rotating member 140 are located. Optionally, in the flattened state, in the direction from the second covering part 150 to the fixed structure 101, the distance between the surface where the second clearance part 151 and the third rotating member 140 are located gradually increases in the thickness direction along the rotating shaft assembly 10, or increases first and then decreases. The implementation method is the same as that of the first clearance part 131 in the above embodiment, and will not be described again here.

[0080] Please refer to Figure 20 and Figure 22When the second clearance portion 151 forms a fourth sub-clearance space 153b at the rotatable connection between the fourth rotating member 141 and the fixed structure 101, the bending of at least a portion of the second clearance portion 151 relative to the second covering portion 150 can be understood as at least a portion of the second clearance portion 151 being connected at one end to the second covering portion 150, and the other end of at least a portion of the second clearance portion 151 extending toward the side away from the fourth rotating member 141. At this time, in the flattened state, the distance between the second clearance portion 151 and the surface where the fourth rotating member 141 is located in the thickness direction along the shaft assembly 10 is greater than the distance between the surface where the second covering portion 150 and the fourth rotating member 141 are located. Optionally, in the flattened state, in the direction from the second covering part 150 to the fixed structure 101, the distance between the surface where the second clearance part 151 and the fourth rotating member 141 are located gradually increases in the thickness direction along the rotating shaft assembly 10, or increases first and then decreases. The implementation method is the same as that of the first clearance part 131 in the above embodiment, and will not be described again here.

[0081] When the pivot assembly 10 is in a flattened state, the thickness direction of the pivot assembly 10 can be referenced. Figure 19 and Figure 20 As shown in the Z-axis direction, when the rotating shaft assembly 10 is in the merged state, the thickness direction of the rotating shaft assembly 10 can be referenced. Figure 21 and Figure 22 As shown in the Z-axis direction.

[0082] Optionally, the third rotating member 140 is symmetrical to the first rotating member 120 about the central axis of the fixed structure 101, the fourth rotating member 141 is symmetrical to the second rotating member 121 about the central axis of the fixed structure 101, and the third covering member 105 is symmetrical to the first covering member 103 about the central axis of the fixed structure 101.

[0083] By further including a second rotating shaft mechanism 104 and a third cover 105 in the rotating shaft assembly 10, the third cover 105 includes a second cover portion 150 and a second clearance portion 151. Since the second cover portion 150 covers the back side of the third rotating member 140 and / or the fourth rotating member 141, the third cover 105 can achieve the purpose of shielding the third rotating member 140 and / or the fourth rotating member 141, preventing the components of the second rotating shaft mechanism 104 from being exposed. Furthermore, since the second clearance portion 151 is bent relative to the second cover portion 150 and within the second rotating shaft mechanism 104... A second clearance space 153 is formed at the rotational connection between the third cover 105 and the fixed structure 101. By designing the structure of the third cover 105, the rotational interference of the third cover 105 with the third rotating member 140 and / or the fourth rotating member 141 can be avoided. The second clearance space 153 provides a certain position for the structure at the rotational connection between the third rotating member 140 and / or the fourth rotating member 141 and the fixed structure 101, so as to improve the space utilization rate of the rotating shaft assembly 10 in the thickness direction and achieve the thickness reduction of the rotating shaft assembly 10.

[0084] In other words, by making the third cover 105 include a second cover portion 150 and a second clearance portion 151, with the second clearance portion 151 bent relative to the second cover portion 150, and forming a second clearance space 153 at the rotational connection between the second pivot mechanism 104 and the fixed structure 101, when the second clearance space 153 does not accommodate the components that achieve the rotational connection between the second pivot mechanism 104 and the fixed structure 101, the formation of the second clearance space 153 can prevent the second pivot mechanism 104, the fixed structure 101, and the third cover 105 from rotating or interfering with each other during assembly. When the component 53 accommodates the second pivot mechanism 104 and the fixed structure 101 for rotatable connection, the formation of the second clearance space 153 is beneficial to thinning the other side of the pivot assembly 10 while meeting the thickness requirements of the second pivot mechanism 104. In addition, when the thickness of the pivot assembly 10 is not reduced, the formation of the second clearance space 153 is also beneficial to increasing the thickness of the second pivot mechanism 104, thereby enhancing the structural strength of the second pivot mechanism 104 and improving the torque on the other side of the pivot assembly 10, so as to achieve a good hovering effect on the other side of the pivot assembly 10.

[0085] In one possible embodiment, please refer to Figure 13 , Figure 23 and Figure 24 , Figure 23 for Figure 12 The schematic diagram of the structure of the first cover 103 in the rotating shaft assembly 10 is shown. Figure 24 for Figure 12The diagram shows the structure of the first rotating member 120 in the rotating shaft assembly 10. A first clearance portion 131 forms a first sub-clearance space 133a at the rotatable connection between the first rotating member 120 and the fixed structure 101. The fixed structure 101 includes at least one first rotatable connection portion 113, and the first rotating member 120 includes at least one second rotatable connection portion 1201. The first rotating member 120 is rotatably connected to the fixed structure 101 through the cooperation of the second rotatable connection portion 1201 and the first rotatable connection portion 113. The first clearance portion 131 includes at least one first sub-clearance portion 131a. The first sub-clearance portion 131a is bent relative to the first covering portion 130 toward the side opposite to the first rotating member 120, and forms the first sub-clearance space 133a on the side toward the second rotatable connection portion 1201.

[0086] The number of first rotating connecting portions 113 can be one or more. The number of second rotating connecting portions 1201 can be one or more. The number of first sub-avoiding portions 131a can be one or more. In this embodiment, taking the fixed structure 101 including six first rotating connecting portions 113, the first rotating member 120 including six second rotating connecting portions 1201, and the first avoidance portion 131 including six first sub-avoiding portions 131a as an example, the number of first rotating connecting portions 113, the number of second rotating connecting portions 1201, and the number of first sub-avoiding portions 131a can be the same. The first rotating member 120 may also include a first rotating main body 1200. The second rotating connecting portion 1201 is disposed on one side of the first rotating main body 1200. The second rotating connecting portion 1201 and the first rotating main body 1200 can be integrally connected, or they can be fixedly connected by a detachable or non-detachable method. In this embodiment, taking the second rotating connecting portion 1201 and the first rotating main body 1200 as integrally connected as an example. The first rotating main body 1200 can be in the shape of a flat plate or an arc-shaped plate, and can be used to support the flexible display screen 200. The second rotating connecting part 1201 can be provided on the side of the first rotating main body 1200 away from the flexible display screen 200.

[0087] Optionally, one of the first rotating connecting portion 113 and the second rotating connecting portion 1201 may have an arcuate groove, and the other of the first rotating connecting portion 113 and the second rotating connecting portion 1201 may include an arcuate block. By assembling the arcuate block in the arcuate groove and enabling it to move along the arcuate groove, a rotating connection between the first rotating member 120 and the fixed structure 101 can be achieved. Alternatively, one of the first rotating connecting portion 113 and the second rotating connecting portion 1201 may include a first arcuate block and a second arcuate block. A first arc groove is formed between the first arc block and the second arc block. The other of the first rotating connection part 113 and the second rotating connection part 1201 may include a third arc block and a fourth arc block. A second arc groove is formed between the third arc block and the fourth arc block. By assembling the third arc block in the first arc groove and enabling it to move along the first arc groove, and assembling the second arc block in the second arc groove and enabling it to move along the second arc groove, a rotating connection between the first rotating member 120 and the fixed structure 101 can be achieved.

[0088] When the rotating shaft assembly 10 is in a flattened state, one of the first rotating connection portion 113 and the second rotating connection portion 1201 can partially extend into the first sub-avoidance space 133a.

[0089] This embodiment achieves the formation of a first sub-avoidance space 133a at the rotational connection between the first rotating member 120 and the fixed structure 101 by the first avoidance part 131. This not only prevents the first covering member 103 from interfering with the first rotating member 120, but also helps to improve the space utilization rate between the first covering member 103 and the first rotating member 120 in the thickness direction. In this way, the thickness of the rotating shaft assembly 10 can be reduced while ensuring the connection strength and stability between the first rotating member 120 and the fixed structure 101. Understandably, without increasing the thickness of the first rotating connection 113 and / or the second rotating connection 1201, the first sub-avoidance space 133a can provide a certain position for the arrangement of the first rotating connection 113 or the second rotating connection 1201, thereby improving the compactness between the first cover 103, the fixed structure 101, and the first rotating member 120, which is beneficial for reducing the thickness of the rotating shaft assembly 10 at this point. However, if the thickness of the first rotating connection 113 and / or the second rotating connection 1201 is increased, the first sub-avoidance space 133a can provide a certain position for the increased thickness of the first rotating connection 113 or the second rotating connection 1201, thereby improving the connection strength between the first rotating member 120 and the fixed structure 101, thereby increasing the torque of the first rotating member 120 and better achieving the hovering of the first rotating member 120.

[0090] Please refer to Figure 19 , Figure 25 and Figure 26 , Figure 25 for Figure 18 The schematic diagram of the structure of the third cover 105 in the rotating shaft assembly 10 is shown. Figure 26 for Figure 18 The diagram shows the structure of the third rotating member 140 in the rotating shaft assembly 10. The second clearance portion 151 forms a third sub-clearance space 153a at the rotatable connection between the third rotating member 140 and the fixed structure 101. The fixed structure 101 further includes a seventh rotatable connection portion 115, and the third rotating member 140 includes an eighth rotatable connection portion 1401. The third rotating member 140 is rotatably connected to the fixed structure 101 through the cooperation of the eighth rotatable connection portion 1401 and the seventh rotatable connection portion 115. The second clearance portion 151 includes a third sub-clearance portion 151a, which bends relative to the second covering portion 150 toward the side opposite to the third rotating member 140, and forms the third sub-clearance space 153a on the side toward the eighth rotatable connection portion 1401. In this embodiment, the second avoidance part 151 forms a third sub-avoidance space 153a at the rotational connection between the third rotating member 140 and the fixed structure 101. The scheme and effect are similar to those of the first avoidance part 131 forming a first sub-avoidance space 133a at the rotational connection between the first rotating member 120 and the fixed structure 101 in the above embodiment. Therefore, it will not be described in detail again.

[0091] In one possible embodiment, please refer to Figure 12 and Figure 13 The first rotating connection portion 113 includes a first sub-rotating connection portion 1130 and a second sub-rotating connection portion 1131. An arcuate groove is formed between the first sub-rotating connection portion 1130 and the second sub-rotating connection portion 1131. The second rotating connection portion 1201 includes at least one arcuate block located within the arcuate groove. The first sub-avoidance portion 131a, the first sub-rotating connection portion 1130, and the second sub-rotating connection portion 1131 are arranged sequentially along the thickness direction of the rotating shaft assembly 10 when the rotating shaft assembly 10 is in a flattened state, and one end of the first sub-rotating connection portion 1130 extends into the first sub-avoidance space 133a.

[0092] Understandably, in this embodiment, the first rotating member 120 and the fixed structure 101 are rotatably connected through the cooperation of an arc groove and an arc block. The first sub-rotational connection portion 1130 has a first arc surface facing the second sub-rotational connection portion 1131. The second sub-rotational connection portion 1131 has a second arc surface facing the second sub-rotational connection portion 1131. An arc groove is formed between the first and second arc surfaces. This application does not specifically limit the number of arc blocks included in the second sub-rotational connection portion 1131. Optionally, the second sub-rotational connection portion 1131 may be integrally formed as a single arc block, or the second sub-rotational connection portion 1131 may include multiple arc blocks, which are spaced apart along the rotation axis of the first rotating member 120 relative to the fixed seat. By including multiple spaced-apart arc blocks in the second sub-rotational connection portion 1131, it is beneficial to achieve a lighter weight for the first rotating member 120. The arc blocks include a third arc surface and a fourth arc surface arranged opposite to each other. When the first rotating member 120 rotates relative to the fixed structure 101, the second sub-rotating connecting part 1131 rotates in the arc groove. At this time, the third arc surface moves in contact with the first arc surface, and the fourth arc surface moves in contact with the second arc surface.

[0093] Since the first rotating member 120 is rotatably connected to the fixed structure 101 through the cooperation of the arc groove and the arc block, the first sub-rotating connection part 1130, the second sub-rotating connection part 1131, and the second rotating connection part 1201 need to meet a certain thickness to ensure the strength of the first rotating shaft mechanism 102 and prevent it from being damaged. Therefore, by making the first sub-avoidance part 131a, the first sub-rotating connection part 1130, the second rotating connection part 1201, and the second sub-rotating connection part 1131 move along the thickness of the rotating shaft assembly 10 when the rotating shaft assembly 10 is in a flattened state, Arranged sequentially, one end of the first sub-rotational connection portion 1130 extends into the first sub-clearance space 133a. That is, the first sub-clearance space 133a is formed on the side of the first sub-clearance portion 131a facing the second rotational connection portion 1201. The first sub-clearance space 133a provides a certain space for the structural design of the first sub-rotational connection portion 1130. This effectively utilizes the space formed by the first sub-clearance portion 131a to accommodate the first sub-rotational connection portion 1130, thus ensuring that the thickness of the rotating shaft assembly 10 does not increase after the first cover member 103 is installed. In other words, the thickness of the rotating shaft assembly 10 can be substantially equal to the thickness of the first rotating shaft mechanism 102.

[0094] Optional, please refer to Figure 12 and Figure 13 The fixing structure 101 includes a base 110 and a second cover 112. The second cover 112 covers the back side of the base 110 and is fixedly connected to the base 110. The base 110 includes a second sub-rotational connection portion 1131. The second cover 112 includes a first sub-rotational connection portion 1130.

[0095] The second cover 112 covering the back side of the base 110 can be understood as the second cover 112 covering the side of the base 110 away from the flexible display screen 200. The fixed connection between the base 110 and the second cover 112 can be achieved through methods including but not limited to threaded connection, bonding, welding, and riveting. It is understood that during the switching process between the flattened and folded states of the rotating shaft assembly 10, neither the base 110 nor the second cover 112 moves.

[0096] In this embodiment, the fixing structure 101 includes a base 110 and a second cover 112. The second cover 112 covers the back side of the base 110 and includes a first sub-rotational connection portion 1130. Since one end of the first sub-rotational connection portion 1130 extends into the first sub-avoidance space 133a, when the rotating shaft assembly 10 is in the flattened state, the first sub-rotational connection portion 1130 of the second cover 112 and the first avoidance portion 131 of the first cover 103 are overlapped. Thus, in the flattened state, the second cover 112 and the first cover 103 can form a good shielding effect.

[0097] The surface of the first covering part 130 facing away from the first rotating member 120 is flat. The surface of the first sub-avoiding part 131a facing away from the first rotating member 120 is curved. The surface of the first sub-avoiding part 131a facing the first rotating member 120 is inclined or concave curved. The surface of the second covering part 112 facing away from the base 110 is flat.

[0098] In this application, the surface of the first covering portion 130 facing away from the first rotating member 120 can also be understood as the back surface of the first covering portion 130, that is, the surface of the first covering portion 130 facing away from the flexible display screen 200. Similarly, the surface of the first sub-avoiding portion 131a facing away from the first rotating member 120 can also be understood as the back surface of the first sub-avoiding portion 131a, that is, the surface of the first sub-avoiding portion 131a facing away from the flexible display screen 200. The surface of the first sub-avoiding portion 131a facing the first rotating member 120 can also be understood as the front surface of the first covering portion 130, that is, the surface of the first sub-avoiding portion 131a facing the flexible display screen 200. The surface of the second covering member 112 facing away from the base 110 can also be understood as the back surface of the second covering member 112, that is, the surface of the second covering member 112 facing away from the flexible display screen 200. The back surface of the first sub-avoiding portion 131a can be a concave arc surface or a convex arc surface. In this application, the descriptions of concave and convex are relative to the structure itself. Specifically, when the back surface of the first sub-avoidance portion 131a is a concave arc surface, the back surface of the first sub-avoidance portion 131a is recessed inwards, and in this case, the back surface of the first sub-avoidance portion 131a is recessed towards the direction of approaching the second rotating connection portion 1201. Conversely, when the back surface of the first sub-avoidance portion 131a is a convex arc surface, the back surface of the first sub-avoidance portion 131a convexes outwards, and in this case, the back surface of the first sub-avoidance portion 131a convexes away from the second rotating connection portion 1201. Similarly, when the front surface of the first sub-avoidance portion 131a is a concave arc surface, the front surface of the first sub-avoidance portion 131a is recessed away from the second rotating connection portion 1201. When the front surface of the first sub-avoidance portion 131a is a sloped surface, the first sub-avoidance portion 131a is inclined at a certain angle relative to the first covering portion 130. In this embodiment of the application, the back side of the first sub-avoidance part 131a is a concave arc surface, and the front side of the first sub-avoidance part 131a is a sloping surface.

[0099] By making the surface of the first covering portion 130 facing away from the first rotating member 120 flat, and the surface of the second covering member 112 facing away from the base 110 flat, a planar shield can be formed on the back side of the rotating shaft assembly 10, improving the flatness of the rotating shaft assembly 10. By making the surface of the first sub-avoidance portion 131a facing away from the first rotating member 120 curved, an arc transition can be formed between the back of the first covering portion 130 and the back of the second covering member 112, improving the continuity and roundness of the appearance of the rotating shaft assembly 10. By making the surface of the first sub-avoidance portion 131a facing the first rotating member 120 inclined or concave arc, the first sub-avoidance portion 131a can be bent relative to the first covering portion 130 facing away from the first rotating member 120, and a first sub-avoidance space 133a can be formed on the side facing the second rotating connection portion 1201.

[0100] Please refer to Figure 18and Figure 19 The scheme of the first rotating member 120 and the fixed structure 101 described in the above embodiments is applicable to the scheme of the third rotating member 140 and the fixed structure 101. That is, the seventh rotating connection part 115 may include a third sub-rotating connection part 1150 and a fourth sub-rotating connection part 1151, and an arc groove is formed between the third sub-rotating connection part 1150 and the fourth sub-rotating connection part 1151. The eighth rotating connection part 1401 includes at least one arc block located in the arc groove. The third sub-avoidance part 151a, the third sub-rotating connection part 1150 and the fourth sub-rotating connection part 1151 are in the rotating shaft assembly 1 When the components are in a flattened state, they are arranged sequentially along the thickness direction of the rotating shaft assembly 10, and one end of the third sub-rotating connection 1150 extends into the third sub-avoidance space 153a; the base 110 also includes a fourth sub-rotating connection 1151, and the second cover 112 also includes a third sub-rotating connection 1150; and the surface of the second cover 150 facing away from the third rotating member 140 is a plane, the surface of the third sub-avoidance 151a facing away from the third rotating member 140 is an arc surface, and the surface of the third sub-avoidance 151a facing the third rotating member 140 is a slope or an inwardly concave arc surface.

[0101] In another possible embodiment, please refer to Figure 14 and Figure 27 , Figure 27 for Figure 12 The diagram shows the structure of the second rotating member 121 in the rotating shaft assembly 10. The first clearance portion 131 also forms a second sub-clearance space 133b at the rotatable connection between the second rotating member 121 and the fixed structure 101. The fixed structure 101 includes a third rotatable connection portion 114. The second rotating member 121 includes a fourth rotatable connection portion 1210. The second rotating member 121 is rotatably connected to the fixed structure 101 through the cooperation of the fourth rotatable connection portion 1210 and the third rotatable connection portion 114. The first clearance portion 131 includes a second sub-clearance portion 131b, which bends relative to the first covering portion 130 toward the side opposite to the second rotating member 121, and forms the second sub-clearance space 133b on the side toward the fourth rotatable connection portion 1210.

[0102] The second sub-avoidance space 133b is located on the side of the second sub-avoidance part 131b facing the second rotating member 121. When the first rotating shaft mechanism 102 switches between the flattened state and the folded state, the fourth rotating connection part 1210 can extend into the second sub-avoidance space 133b without contacting the second sub-avoidance part 131b.

[0103] This embodiment enables the first clearance part 131 to form a second sub-clearance space 133b at the rotational connection between the second rotating member 121 and the fixed structure 101. This not only prevents the first cover member 103 from interfering with the second rotating member 121, but also improves the space utilization rate between the first cover member 103 and the second rotating member 121 in the thickness direction. In this way, the thickness of the rotating shaft assembly 10 can be reduced while ensuring the connection strength and stability between the second rotating member 121 and the fixed structure 101. Understandably, without increasing the thickness of the third rotating connection 114 and / or the fourth rotating connection 1210, the second sub-avoidance space 133b can provide a certain position for the arrangement of the third rotating connection 114 or the fourth rotating connection 1210, thereby improving the compactness between the first cover member 103, the fixed structure 101, and the second rotating member 121, which is beneficial for reducing the thickness of the rotating shaft assembly 10 at this point. However, if the thickness of the third rotating connection 114 and / or the fourth rotating connection 1210 is increased, the second sub-avoidance space 133b can provide a certain position for the increased thickness of the third rotating connection 114 or the fourth rotating connection 1210, thereby improving the connection strength between the second rotating member 121 and the fixed structure 101, thereby increasing the torque of the second rotating member 121 and better achieving the hovering of the second rotating member 121.

[0104] Please refer to Figure 20 and Figure 28 , Figure 28 for Figure 18 The diagram shows the structure of the fourth rotating member 141 in the rotating shaft assembly 10. The second clearance portion 151 also forms a fourth sub-clearance space 153b at the rotatable connection between the fourth rotating member 141 and the fixed structure 101. The fixed structure 101 further includes a ninth rotatable connection portion 116, and the fourth rotating member 141 includes a tenth rotatable connection portion 1410. The fourth rotating member 141 is rotatably connected to the fixed structure 101 through the cooperation of the tenth rotatable connection portion 1410 and the ninth rotatable connection portion 116. The second clearance portion 151 includes a fourth sub-clearance portion 151b, which bends relative to the second covering portion 150 toward the side opposite to the fourth rotating member 141, and forms a fourth sub-clearance space 153b on the side toward the tenth rotatable connection portion 1410. In this embodiment, the scheme and effect of the second avoidance part 151 forming a fourth sub-avoidance space 153b at the rotational connection between the fourth rotating member 141 and the fixed structure 101 are similar to those of the scheme and effect of the first avoidance part 131 forming a second sub-avoidance space 133b at the rotational connection between the second rotating member 121 and the fixed structure 101 in the above embodiment, and will not be described in detail again.

[0105] Optionally, one of the third rotating connecting portion 114 and the fourth rotating connecting portion 1210 may have a shaft hole, and the other of the third rotating connecting portion 114 and the fourth rotating connecting portion 1210 may have a rotating shaft. By assembling the rotating shaft into the shaft hole and enabling it to rotate, the second rotating member 121 and the fixed structure 101 can be rotatably connected. Alternatively, the third rotating connecting portion 114 and the fourth rotating connecting portion 1210 may each have a first shaft hole and a second shaft hole. The rotating shaft assembly 10 may also include a pin, with both ends of the pin respectively assembled into the first shaft hole and the second shaft hole, thereby achieving the rotatable connection between the second rotating member 121 and the fixed structure 101. It can be understood that the second rotating member 121 and the fixed structure 101 are rotatably connected through the cooperation of the rotating shaft and the shaft hole.

[0106] In one possible embodiment, the fourth rotating connection portion 1210 has a shaft hole. Since the second rotating member 121 and the fixed structure 101 are rotatably connected by the cooperation of the rotating shaft and the shaft hole, the fourth rotating connection portion 1210 needs to have a shaft hole. Therefore, the fourth rotating connection portion 1210 needs to meet a certain thickness to ensure the connection strength between the second rotating member 121 and the fixed structure 101 and to avoid damage. Therefore, by bending the second sub-avoidance portion 131b relative to the first covering portion 130 and forming a second sub-avoidance space 133b at the cooperation point between the fourth rotating connection portion 1210 and the third rotating connection portion 114, the second sub-avoidance space 133b provides a certain position for the structural design of the fourth rotating connection portion 1210. This helps to increase the thickness of the fourth rotating connection portion 1210 and strengthen the connection strength between the second rotating member 121 and the fixed structure 101.

[0107] The axis of rotation of the second rotating member 121 relative to the fixed structure 101 is parallel to and not collinear with the axis of rotation of the first rotating member 120 relative to the fixed structure 101. Optionally, the axis of rotation of the second rotating member 121 relative to the fixed structure 101 is further away from the flexible display screen 200 along the thickness direction of the rotating shaft assembly 10 than the axis of rotation of the first rotating member 120 relative to the fixed structure 101.

[0108] Since both the first rotating member 120 and the second rotating member 121 are rotatably connected to the fixed structure 101, making the rotation axis of the second rotating member 121 relative to the fixed structure 101 parallel and non-collinear with the rotation axis of the first rotating member 120 relative to the fixed structure 101 not only achieves the same-direction rotation of the first rotating member 120 and the second rotating member 121 relative to the fixed structure 101 but also improves the motion accuracy of the first rotating shaft mechanism 102. Furthermore, the rotatable connection between the first rotating member 120 and the fixed structure 101 via a circular arc groove and a circular arc block, and the rotatable connection between the second rotating member 121 and the fixed structure 101 via a rotating shaft and a shaft hole, facilitates ensuring that the rotation axis of the second rotating member 121 relative to the fixed structure 101 is parallel and non-collinear with the rotation axis of the first rotating member 120 relative to the fixed structure 101. This also avoids interference between the rotatable connection structure of the first rotating member 120 and the fixed structure 101 and the flexible display screen 200.

[0109] In one possible embodiment, please refer to Figure 20 and Figure 27 The second rotating member 121 also includes a first gear portion 1212. The first gear portion 1212 is connected to the fourth rotating connection portion 1210. During the switching between the flattened state and the folded state of the first rotating shaft mechanism 102, one end of the first gear portion 1212 extends into the second sub-avoidance space 133b.

[0110] The first gear section 1212 may include at least one first gear. The first gear may be a spur gear or a helical gear. During the switching between the flattened state and the folded state of the first rotating shaft mechanism 102, the second rotating member 121 rotates relative to the fixed structure 101. At this time, one end of the first gear section 1212 extends into the second sub-avoidance space 133b, which can improve the space utilization between the first cover member 103 and the fourth rotating connection section 1210. During the rotation of the second rotating member 121 relative to the fixed structure 101, the first gear section 1212 may contact the second sub-avoidance section 131b. At this time, the friction between the first gear section 1212 and the second sub-avoidance section 131b helps to increase the torque of the second rotating member 121, achieving a better hovering effect for the second rotating member 121. Alternatively, the first gear section 1212 may not contact the second sub-avoidance section 131b, in which case the rotation of the second rotating member 121 is smoother.

[0111] This embodiment, by including a first gear portion 1212 on the fourth rotating connection portion 1210 in the second rotating member 121, facilitates the synchronous movement of both sides of the rotating shaft assembly 10. After the first gear portion 1212 is provided, the thicknesses of the fourth rotating connection portion 1210 and the first gear portion 1212 overlap. If the second sub-avoidance portion 131b of the first cover portion 103 is not bent relative to the first cover portion 130, the second rotating member 121 is prone to interfering with the first cover portion 103 during rotation relative to the fixed structure 101. Therefore, it is necessary to increase the height between the first cover portion 103 and the second rotating member 121 to avoid interference, which would increase the thickness of the rotating shaft assembly 10. However, by bending the second sub-avoidance portion 131b relative to the first cover portion 130, the resulting second sub-avoidance space 133b can prevent the second rotating member 121 from interfering with the first cover portion 103 during rotation relative to the fixed structure 101, and the thickness of the rotating shaft assembly 10 does not increase. Furthermore, during the switching process between the flattened state and the folded state of the first rotating shaft mechanism 102, the first gear part 1212 extends into the second sub-avoidance space 133b. That is, during the rotation of the second rotating member 121 relative to the fixed structure 101, the first gear part 1212 extends into the second sub-avoidance space 133b. In this way, while preventing interference between the second rotating member 121 and the first cover member 103, it can avoid the situation where the second sub-avoidance space 133b is designed to be too large, resulting in a loose fit between the second rotating member 121 and the first cover member 103, wasted space, and an increase in the thickness of the rotating shaft assembly 10.

[0112] Optionally, the surface of the second sub-avoiding portion 131b facing away from the second rotating member 121 is an arc surface. The surface of the second sub-avoiding portion 131b facing the second rotating member 121 is a slope or a concave arc surface.

[0113] The surface of the second sub-avoiding portion 131b facing away from the second rotating member 121 can also be understood as the back surface of the second sub-avoiding portion 131b, that is, the surface of the second sub-avoiding portion 131b facing away from the flexible display screen 200. The surface of the second sub-avoiding portion 131b facing the second rotating member 121 can also be understood as the front surface of the second sub-avoiding portion 131b, that is, the surface of the second sub-avoiding portion 131b facing the flexible display screen 200. The back surface of the second sub-avoiding portion 131b can be a concave arc surface or a convex arc surface. When the back surface of the second sub-avoidance portion 131b is a concave arc surface, the back surface of the second sub-avoidance portion 131b is recessed inward, and at this time, the back surface of the second sub-avoidance portion 131b is recessed towards the direction of approaching the fourth rotating connection portion 1210. Conversely, when the back surface of the second sub-avoidance portion 131b is a convex arc surface, the back surface of the second sub-avoidance portion 131b is convex outward, and at this time, the back surface of the second sub-avoidance portion 131b is convex away from the fourth rotating connection portion 1210. Similarly, when the front surface of the second sub-avoidance portion 131b is a concave arc surface, the front surface of the second sub-avoidance portion 131b is recessed away from the fourth rotating connection portion 1210. When the front surface of the second sub-avoidance portion 131b is a sloped surface, the second sub-avoidance portion 131b is inclined at a certain angle relative to the first covering portion 130. In this embodiment of the application, the back side of the second sub-avoidance part 131b is a concave arc surface, and the front side of the second sub-avoidance part 131b is a concave arc surface.

[0114] By making the surface of the second sub-avoidance portion 131b facing away from the second rotating member 121 curved, an arc transition can be formed between the back of the first covering portion 130 and the back of the second covering member 112, improving the appearance continuity and roundness of the rotating shaft assembly 10. By making the surface of the second sub-avoidance portion 131b facing the second rotating member 121 inclined or concave arc surface, the second sub-avoidance portion 131b can be bent relative to the first covering portion 130 facing away from the second rotating member 121, and a second sub-avoidance space 133b can be formed on the side facing the fourth rotating connection portion 1210.

[0115] The scheme of the second rotating member 121 and the fixed structure 101 described in the above embodiments is applicable to the scheme of the fourth rotating member 141 and the fixed structure 101. That is, the fourth rotating member 141 and the fixed structure 101 can be rotatably connected by the cooperation of the rotating shaft and the shaft hole. The tenth rotating connection part 1410 has a shaft hole. The rotation axis of the fourth rotating member 141 relative to the fixed structure 101 is parallel and not collinear with the rotation axis of the third rotating member 140 relative to the fixed structure 101. The surface of the fourth sub-avoiding part 151b away from the fourth rotating member 141 is an arc surface, and the surface of the fourth sub-avoiding part 151b facing the fourth rotating member 141 is a slope or an inwardly concave arc surface.

[0116] Please refer to Figure 20 and Figure 28 The fourth rotating member 141 also includes a second gear portion 1412. The second gear portion 1412 is connected to the tenth rotating connection portion 1410. The second gear portion 1412 meshes with the first gear portion 1212 of the second rotating member 121. The second gear portion 1412 may include at least one second gear. The second gear may be a spur gear or a helical gear. In this embodiment, the synchronous rotation of the first rotating shaft mechanism 102 and the second rotating shaft mechanism 104 can be achieved by the cooperation of the second gear portion 1412 of the fourth rotating member 141 and the first gear portion 1212 of the second rotating member 121, thereby reducing the number of parts in the rotating shaft assembly 10. During the switching between the flattened state and the folded state of the second rotating shaft mechanism 104, one end of the second gear portion 1412 can extend into the fourth sub-avoidance space 153b.

[0117] Further, please refer to Figures 29 to 32 , Figure 29 for Figure 17 The schematic diagram shown illustrates that the rotating shaft assembly 10 also includes a first moving member 122 and a second moving member 142. Figure 30 for Figure 29 An exploded view of the rotating shaft assembly 10 shown. Figure 31 for Figure 29 The diagram shows a cross-sectional structure of the rotating shaft assembly 10 in a flattened state. Figure 32 for Figure 29 The diagram shows another cross-sectional view of the rotating shaft assembly 10 in its flattened state. The first rotating shaft mechanism 102 also includes a first moving member 122. The first moving member 122 is located on the side of the first rotating member 120 and the second rotating member 121 facing away from the fixed structure 101. The first moving member 122 is movably connected to the first rotating member 120 and also movably connected to the second rotating member 121. The first covering member 103 is connected to at least one of the first moving member 122, the first rotating member 120, and the second rotating member 121.

[0118] Understandably, the first moving member 122, the first rotating member 120, and the second rotating member 121 are located on the same side of the fixed structure 101, and the first rotating member 120 and the second rotating member 121 are respectively connected between the fixed structure 101 and the first moving member 122. The movable connection can be a rotational connection or a sliding connection. Optionally, the first moving member 122 is rotatably connected to one of the first rotating member 120 and the second rotating member 121, and slidably connected to the other of the first rotating member 120 and the second rotating member 121; or, the first moving member 122 is rotatably connected to the first rotating member 120, and the first moving member 122 is rotatably connected to the second rotating member 121; or, the first moving member 122 is slidably connected to the first rotating member 120, and the first moving member 122 is slidably connected to the second rotating member 121.

[0119] Optionally, the first cover 103 is connected to one of the first moving member 122, the first rotating member 120, and the second rotating member 121. For example, the first cover 103 is fixedly connected to one of the first moving member 122, the first rotating member 120, and the second rotating member 121; or, the first cover 103 is connected to two of the first moving member 122, the first rotating member 120, and the second rotating member 121. For example, the first cover 103 is fixedly connected to one of the first rotating member 120, the second rotating member 121, and the first moving member 122. One of the moving members 122 is movably connected to form a higher pair connection with another of the first rotating member 120, the second rotating member 121, and the first moving member 122; alternatively, the first covering member 103 is connected to all three of the moving members 122, the first rotating member 120, and the second rotating member 121. For example, the first covering member 103 forms a higher pair connection with the first rotating member 120, the first covering member 103 forms a higher pair connection with the second rotating member 121, and the first covering member 103 forms a higher pair connection with the first moving member 122. This embodiment ensures that the rotation shaft assembly 10 has one degree of freedom, thus giving the rotation shaft assembly 10 a definite motion.

[0120] The first moving component 122 is connected to the first housing assembly 20. In one possible embodiment, the first moving component 122 is fixedly connected to the first middle frame 201 of the first housing assembly 20. The fixed connection between the first moving component 122 and the first middle frame 201 includes, but is not limited to, threaded connection, snap-fit ​​connection, riveting connection, welding, and bonding.

[0121] In this embodiment, by including a first moving member 122 in the first rotating shaft mechanism 102, the fixed structure 101, the first rotating member 120, the second rotating member 121, and the first moving member 122 form a four-bar linkage, which can balance the stability and vibration damping of the rotating shaft assembly 10. By movably connecting the first moving member 122 to the first rotating member 120 and to the second rotating member 121, the rotating shaft assembly 10 can achieve one degree of freedom, possessing a defined movement. Furthermore, by connecting the first covering member 103 to at least one of the first moving member 122, the first rotating member 120, and the second rotating member 121, the first covering member 103 can be linked with the first rotating shaft mechanism 102. Thus, when the first rotating shaft mechanism 102 is in a flattened state, the first covering member 103 is also in a flattened state; when the first rotating shaft mechanism 102 is in a closed state, the first covering member 103 is also in a closed state.

[0122] In one possible embodiment, please refer to Figure 31 and Figure 32The first moving part 122 is rotatably connected to the first rotating part 120, the first moving part 122 is slidably connected to the second rotating part 121, and the first covering part 103 is fixedly connected to the first moving part 122.

[0123] The first moving component 122 and the first rotating component 120 are rotatably connected in ways including, but not limited to, a rotatable connection through the cooperation of an arcuate groove and an arcuate block, or a rotatable connection through the cooperation of a rotating shaft and a shaft hole. The first moving component 122 and the second rotating component 121 are slidably connected in ways including, but not limited to, a slidable connection through the cooperation of a sliding groove and a sliding block. The first covering component 103 and the first moving component 122 are fixedly connected in ways including, but not limited to, threaded connection, snap-fit ​​connection, riveting connection, welding, and bonding.

This helps to reduce creases in the flexible display screen 200 and reduce the tension and pressure on the flexible display screen 200 during the switching between flattened and folded states. By fixing the first covering component 103 to the first moving component 122, the structure of the rotating shaft assembly 10 can be simplified and assembly can be made more convenient.

[0125] Optionally, the first covering member 103 forms a virtual constraint with at least one of the first moving member 122, the first rotating member 120, the second rotating member 121, and the fixed structure 101. In one possible embodiment, the first covering member 103 may slide with the first moving member 122 to form a virtual constraint, and the first covering member 103 may rotate with the fixed structure 101 to form a virtual constraint.

[0129] In one possible embodiment, the fifth rotating connection portion 1202 may include at least one arcuate block.

The sixth rotating connection portion 1220 may include an arcuate groove. In this embodiment, the first rotating member 120 and the first moving member 122 are rotatably connected through the cooperation of the arcuate block and the arcuate groove.
