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 maintainability of the hinge and its encapsulation after assembly with the housing are relatively poor. Summary of the Invention

[0003] This application provides a hinge assembly, a foldable housing device, and a foldable electronic device that are easy to maintain and improve packaging performance.

[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, at least one second rotating member, and a first sliding member. The first rotating member and the second rotating member are disposed between the first sliding member and the fixed structure. The first rotating member is rotatably connected to the fixed structure and rotatably or slidably connected to the first sliding member. The second rotating member is rotatably connected to the fixed structure and slidably connected to the first sliding member.

[0007] The encapsulation structure includes at least one first encapsulation component, at least one second encapsulation component, and at least one third encapsulation component. The first encapsulation component is fixedly connected to one end of the fixed structure, the second encapsulation component is fixedly connected to one end of the first rotating component, and the third encapsulation component is fixedly connected to one end of the first sliding component. When the first rotating shaft mechanism is in a flattened state and a folded state, the first encapsulation component, the second encapsulation component, and the third encapsulation component are sequentially adjacent to each other.

[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 an encapsulation structure. The first pivot mechanism includes a first rotating component, a second rotating component, and a first sliding component. The first rotating component and the second rotating component are disposed between the first sliding component and the fixed structure. The first rotating component is rotatably connected to the fixed structure and is rotatably or slidably connected to the first sliding component. The second rotating component is rotatably connected to the fixed structure and is slidably connected to the first sliding component. The encapsulation structure includes a first encapsulation component, a second encapsulation component, and a third encapsulation component. The first encapsulation component is fixedly connected to one end of the fixed structure, the second encapsulation component is fixedly connected to one end of the first rotating component, and the third encapsulation component is fixedly connected to one end of the first sliding component. In this way, the first encapsulation component, the second encapsulation component, and the third encapsulation component can be independently disassembled and assembled, making the pivot assembly easy to maintain. When the first pivot mechanism is in a flattened state and a closed state, the first encapsulation component, the second encapsulation component, and the third encapsulation component are sequentially adjacent to each other. In this way, the first encapsulation component, the second encapsulation component, and the third encapsulation component can contact each other in the flattened state and the closed state, so as to improve the encapsulation performance of the pivot assembly.

[0048] The technical solutions provided in this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments described in this application without creative effort are within the protection scope of this application.

[0049] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] Flexible display screen 200 includes, but is not limited to, organic light-emitting diode (OLED) type flexible display screen.

[0054] 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.

[0055] 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.

[0056] 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 combined 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.

[0057] Please refer to Figures 8 to 10 , Figure 8 for Figure 1 The diagram shows a structural schematic of the foldable housing device 100 in a flattened state in the foldable electronic device 1000. Figure 9 for Figure 8 The diagram shows the structure of the foldable housing device 100 in its folded 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.

[0058] 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°.

[0059] 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 10, that is, the pivot assembly 10 folds outward during the switching between a flattened state and a folded state.

[0060] 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°. When the foldable housing device 100 is in a folded state, the angle between the first housing assembly 20 and the second housing assembly 30 is 0° or close to 0°, and the angle between the second housing assembly 30 and the third housing assembly 40 is 0° or close to 0°.

Optionally, the first housing assembly 20 and the first non-bending display portion 21 can be fixedly connected, the second housing assembly 30 and the second non-bending display portion 23 can be fixedly connected, and the third housing assembly 40 and the third non-bending display portion 26 can be fixedly connected.

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 10, and the second rotating shaft assembly 10b is an inward-folding rotating shaft assembly 10. 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.

[0062] Optional, please refer to Figures 8 to 10The first housing assembly 20 includes a first middle frame 201 and a first battery cover 202. Both the first middle frame 201 and the first battery cover 202 are connected to the hinge assembly 10. In one possible embodiment, the first middle frame 201 is fixedly connected to a portion of the structure in the hinge assembly 10, and the first battery cover 202 is fixedly connected to a portion of the structure in the hinge assembly 10. The second housing assembly 30 includes a second middle frame 301 and a second battery cover 302.

[0063] Please refer to Figures 11 to 16 , Figure 11 This is a schematic diagram of the rotating shaft assembly 10 provided in this application embodiment when it is in a flattened state. Figure 12 for Figure 11 An exploded view of the front of the pivot assembly 10 shown. Figure 13 for Figure 11 An exploded view of the rear of the pivot assembly 10 shown. Figure 14 This is a schematic diagram of the rotating shaft assembly 10 provided in this embodiment of the application when it is in a combined state. Figure 15 for Figure 11 The diagram shows an enlarged view of area A when the rotating shaft assembly 10 is in a flattened state. Figure 16 for Figure 14 The diagram shows an enlarged view of region B when the rotating shaft assembly 10 is in the combined state. The rotating shaft assembly 10 includes a fixed structure 101, a first rotating shaft mechanism 102, and an encapsulation structure 103.

[0064] 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.

[0065] 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.

[0066] The first rotating shaft mechanism 102 includes a first rotating member 120, at least one second rotating member 121, and a first sliding member 122. 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, one first sliding member 122, and multiple second rotating members 121. (This application embodiment) Figure 12 , Figure 13 The following example uses three second rotating members 121 (labeled 121a, 121b, and 121c, respectively). The three second rotating members 121 have similar structures. The first rotating member 120 and the second rotating members 121 are located between the first sliding member 122 and the fixed structure 101.

[0067] The first rotating component 120 is rotatably connected to the fixed structure 101, and the second rotating component 121 is rotatably connected to the fixed structure 101. It can be understood that during the process of the first rotating shaft mechanism 102 switching between the flattened state and the folded state, 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.

[0068] 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.

[0069] 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.

[0070] The first rotating member 120 is rotatably or slidably connected to the first sliding member 122, and the second rotating member 121 is slidably connected to the first sliding member 122. It is understood that during the switching process between the flattened state and the folded state of the first rotating shaft mechanism 102, relative sliding occurs between the second rotating member 121 and the first sliding member 122. In one possible embodiment, the first rotating member 120 is rotatably connected to the first sliding member 122. In this embodiment, during the switching process between the flattened state and the folded state of the first rotating shaft mechanism 102, relative rotation occurs between the first rotating member 120 and the first sliding member 122. In another possible embodiment, the first rotating member 120 is slidably connected to the first sliding member 122. In this embodiment, during the switching process between the flattened state and the folded state of the first rotating shaft mechanism 102, relative sliding occurs between the first rotating member 120 and the first sliding member 122.

[0071] The first sliding member 122 of the first rotating shaft mechanism 102 is connected to the first housing assembly 20. In one possible embodiment, the first sliding member 122 is fixedly connected to the first middle frame 201 of the first housing assembly 20. The fixed connection between the first sliding member 122 and the first middle frame 201 includes, but is not limited to, threaded connection, snap-fit ​​connection, riveting connection, welding, and bonding.

[0072] The encapsulation structure 103 includes at least one first encapsulation member 131, at least one second encapsulation member 132, and at least one third encapsulation member 133. The first encapsulation member 131 is fixedly connected to one end of the fixed structure 101, the second encapsulation member 132 is fixedly connected to one end of the first rotating member 120, and the third encapsulation member 133 is fixedly connected to one end of the first sliding member 122. When the first rotating shaft mechanism 102 is in the flattened state and the folded state, the first encapsulation member 131, the second encapsulation member 132, and the third encapsulation member 133 are sequentially adjacent to each other.

[0073] Understandably, the first encapsulation component 131 is separately connected to the fixed structure, the second encapsulation component 132 is separately connected to the first rotating component 120, and the third encapsulation component 133 is separately connected to the first sliding component 122. During the switching between the flattened and folded states of the rotating shaft assembly 10, the first encapsulation component 131 does not move. During the switching between the flattened and folded states of the first rotating shaft mechanism 102, the second encapsulation component 132 moves relative to the fixed structure 101 under the influence of the first rotating component 120. During the switching between the flattened and folded states of the first rotating shaft mechanism 102, the third encapsulation component 133 moves relative to the fixed structure 101 under the influence of the first sliding component 122. The first encapsulation component 131 and the second encapsulation component 132 are not fixed together. The second encapsulation component 132 and the third encapsulation component 133 are not fixed together. The first encapsulation component 131 and the third encapsulation component 133 are not fixed together.

[0074] The first encapsulation component 131 is fixedly connected to the fixed structure 101 by means including but not limited to threaded connection, snap-fit ​​connection, welding, and bonding. The second encapsulation component 132 is fixedly connected to the first rotating component 120 by means including but not limited to threaded connection, snap-fit ​​connection, welding, and bonding. The third encapsulation component 133 is fixedly connected to the first sliding component 122 by means including but not limited to threaded connection, snap-fit ​​connection, welding, and bonding.

[0075] One end of the fixed structure 101, one end of the first rotating member 120, and one end of the first sliding member 122 can be substantially flush. In one possible embodiment, the encapsulation structure 103 may include two first encapsulation members 131, two second encapsulation members 132, and two third encapsulation members 133. The two first encapsulation members 131 are respectively fixedly connected to both ends of the fixed structure 101 along the axial direction of the rotating shaft assembly 10, the two second encapsulation members 132 are respectively fixedly connected to both ends of the first rotating member 120 along the axial direction of the rotating shaft assembly 10, and the two third encapsulation members 133 are respectively fixedly connected to both ends of the first sliding member 122 along the axial direction of the rotating shaft assembly 10.

[0076] When the first rotating shaft mechanism 102 is in the flattened state and the folded state, the first package 131, the second package 132, and the third package 133 are sequentially adjacent. This can be understood as follows: when the first rotating shaft mechanism 102 is in the flattened state, the first package 131 and the second package 132 are in contact or have a small gap, and the second package 132 and the third package 133 are in contact or have a small gap; when the first rotating shaft mechanism 102 is in the folded state, the first package 131 and the second package 132 are in contact or have a small gap, and the second package 132 and the third package 133 are in contact or have a small gap.

[0077] Thus, when the packaging structure 103 of the rotating shaft assembly 10 is damaged, only the packaging structure 103 can be replaced; when the first rotating shaft mechanism 102 of the rotating shaft assembly 10 is damaged, only the first rotating shaft mechanism 102 can be replaced; and when the first package 131, the second package 132 and the third package 133 are damaged, the packaging structure 103 can be replaced, or only one or more of the damaged packages among the first package 131, the second package 132 and the third package 133 can be replaced.

[0078] The rotating shaft assembly 10 provided in this application includes a fixed structure 101, a first rotating shaft mechanism 102, and an encapsulation structure 103. The first rotating shaft mechanism 102 includes a first rotating member 120, a second rotating member 121, and a first sliding member 122. The first rotating member 120 and the second rotating member 121 are disposed between the first sliding member 122 and the fixed structure 101. The first rotating member 120 is rotatably connected to the fixed structure 101 and rotatably or slidably connected to the first sliding member 122. The second rotating member 121 is rotatably connected to the fixed structure 101 and slidably connected to the first sliding member 122. The encapsulation structure 103 includes a first encapsulation member 131, a second encapsulation member 132, and a third encapsulation member 133. The first encapsulation member 131 is fixedly connected to one end of the fixed structure 101, the second encapsulation member 132, and the third encapsulation member 133. 132 is fixedly connected to one end of the first rotating member 120, and the third encapsulation member 133 is fixedly connected to one end of the first sliding member 122. In this way, the first encapsulation member 131, the second encapsulation member 132, and the third encapsulation member 133 can be independently disassembled and assembled, making the rotating shaft assembly 10 easy to maintain. When the first rotating shaft mechanism 102 is in the flattened state and the folded state, the first encapsulation member 131, the second encapsulation member 132, and the third encapsulation member 133 are adjacent to each other in sequence. In this way, the first encapsulation member 131, the second encapsulation member 132, and the third encapsulation member 133 can contact each other in the flattened state and the folded state, so as to improve the encapsulation performance of the rotating shaft assembly 10, which can improve the sealing performance of the foldable housing device 100 and the foldable electronic device 1000 and prevent the hand from being pinched in the encapsulation position.

[0079] Further, please refer to Figures 17 to 22 , Figure 17 This is another structural schematic diagram of the pivot assembly 10 provided in the embodiments of this application when it is in a flattened state. Figure 18 for Figure 17 An exploded view of the front of the pivot assembly 10 shown. Figure 19 for Figure 17 An exploded view of the rear of the pivot assembly 10 shown. Figure 20 This is a schematic diagram of the rotating shaft assembly 10 provided in this embodiment of the application when it is in a combined state. Figure 21 for Figure 17 The diagram shows an enlarged view of region C when the rotating shaft assembly 10 is in a flattened state. Figure 22 for Figure 20 The diagram shows an enlarged view of region D when the rotating shaft assembly 10 is in the combined state. The rotating shaft assembly 10 also includes a second rotating shaft mechanism 104. The second rotating shaft mechanism 104 is located on the other side of the fixed structure 101.

[0080] The second rotating shaft mechanism 104 includes a third rotating member 140, at least one fourth rotating member 141, and a second sliding member 142. This application does not specify the number of fourth rotating members 141. In one possible embodiment, the second rotating shaft mechanism 104 includes one third rotating member 140, one second sliding member 142, and multiple fourth rotating members 141. (Example from this application) Figure 18 , Figure 19 The following example uses three fourth rotating members 141 (labeled 141a, 141b, and 141c, respectively). The three fourth rotating members 141 have similar structures. The third rotating member 140 and the fourth rotating members 141 are located between the second sliding member 142 and the fixed structure 101.

[0081] The third rotating component 140 is rotatably connected to the fixed structure 101, and the fourth rotating component 141 is rotatably connected to the fixed structure 101. It can be understood that during the process of the second rotating shaft mechanism 104 switching between the flattened state and the folded state, 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.

[0082] 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.

[0083] 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.

[0084] The third rotating member 140 is rotatably or slidably connected to the second sliding member 142, and the fourth rotating member 141 is slidably connected to the second sliding member 142. It is understood that during the switching between the flattened and folded states of the second rotating shaft mechanism 104, relative sliding occurs between the fourth rotating member 141 and the second sliding member 142. In one possible embodiment, the third rotating member 140 is rotatably connected to the second sliding member 142. In this embodiment, during the switching between the flattened and folded states of the second rotating shaft mechanism 104, relative rotation occurs between the third rotating member 140 and the second sliding member 142. In another possible embodiment, the third rotating member 140 is slidably connected to the second sliding member 142. In this embodiment, during the switching between the flattened and folded states of the second rotating shaft mechanism 104, relative sliding occurs between the third rotating member 140 and the second sliding member 142.

[0085] The second sliding member 142 of the second rotating shaft mechanism 104 is connected to the second housing assembly 30. In one possible embodiment, the second sliding member 142 is fixedly connected to the second middle frame 301 of the second housing assembly 30. The methods by which the second sliding member 142 is fixedly connected to the second middle frame 301 include, but are not limited to, threaded connection, snap-fit ​​connection, riveting connection, welding, and bonding.

[0086] The encapsulation structure 103 further includes at least one fourth encapsulation member 134 and at least one fifth encapsulation member 135. The fourth encapsulation member 134 is fixedly connected to one end of the third rotating member 140, and the fifth encapsulation member 135 is fixedly connected to one end of the second sliding member 142. When the second rotating shaft mechanism 104 is in the flattened state and the folded state, the first encapsulation member 131, the fourth encapsulation member 134, and the fifth encapsulation member 135 are sequentially adjacent to each other.

[0087] Understandably, the fourth encapsulation component 134 is separately connected to the first rotating component 120, and the fifth encapsulation component 135 is separately connected to the second sliding component 142. During the switching between the flattened and folded states of the second rotating shaft mechanism 104, the fourth encapsulation component 134 moves relative to the fixed structure 101 under the influence of the third rotating component 140. During the switching between the flattened and folded states of the second rotating shaft mechanism 104, the fifth encapsulation component 135 moves relative to the fixed structure 101 under the influence of the second sliding component 142. The first encapsulation component 131 and the fourth encapsulation component 134 are not fixed together. The fourth encapsulation component 134 and the fifth encapsulation component 135 are not fixed together. The first encapsulation component 131 and the fifth encapsulation component 135 are not fixed together.

[0088] The fourth encapsulation component 134 is fixedly connected to the third rotating component 140 by means including but not limited to threaded connection, snap-fit ​​connection, welding, and bonding. The fifth encapsulation component 135 is fixedly connected to the second sliding component 142 by means including but not limited to threaded connection, snap-fit ​​connection, welding, and bonding.

[0089] One end of the fixed structure 101, one end of the third rotating member 140, and one end of the second sliding member 142 can be substantially flush. In one possible embodiment, the encapsulation structure 103 may include two fourth encapsulation members 134 and two fifth encapsulation members 135. The two fourth encapsulation members 134 are respectively fixedly connected to both ends of the third rotating member 140 along the axial direction of the shaft assembly 10, and the two fifth encapsulation members 135 are respectively fixedly connected to both ends of the second sliding member 142 along the axial direction of the shaft assembly 10.

[0090] When the second rotating shaft mechanism 104 is in the flattened state and the folded state, the first package 131, the fourth package 134, and the fifth package 135 are sequentially adjacent. This can be understood as follows: when the second rotating shaft mechanism 104 is in the flattened state, the first package 131 and the fourth package 134 are in contact or have a small gap, and the fourth package 134 and the fifth package 135 are in contact or have a small gap; when the second rotating shaft mechanism 104 is in the folded state, the first package 131 and the fourth package 134 are in contact or have a small gap, and the fourth package 134 and the fifth package 135 are in contact or have a small gap.

[0091] Thus, when the encapsulation structure 103 of the rotating shaft assembly 10 is damaged, only the encapsulation structure 103 can be replaced; when the second rotating shaft mechanism 104 of the rotating shaft assembly 10 is damaged, only the second rotating shaft mechanism 104 can be replaced; and when the first encapsulation 131, the fourth encapsulation 134 and the fifth encapsulation 135 are damaged, the encapsulation structure 103 can be replaced, or only one or more of the first encapsulation 131, the fourth encapsulation 134 and the fifth encapsulation 135 that are damaged can be replaced.

[0092] In this embodiment, the structure of the fourth encapsulation member 134 is similar to that of the second encapsulation member 132, and the structure of the fifth encapsulation member 135 is similar to that of the third encapsulation member 133. In one possible embodiment, the third rotating member 140 and the first rotating member 120 can be symmetrical about the central axis of the fixed structure 101, the fourth rotating member 141 and the second rotating member 121 can be symmetrical about the central axis of the fixed structure 101, the second sliding member 142 and the first sliding member 122 can be symmetrical about the central axis of the fixed structure 101, the fourth encapsulation member 134 and the second encapsulation member 132 can be symmetrical about the central axis of the fixed structure 101, and the fifth encapsulation member 135 and the third encapsulation member 133 can be symmetrical about the central axis of the fixed structure 101.

[0093] In one possible embodiment, please refer to Figures 23 to 25 , Figure 23 This is a schematic diagram showing the structure in which the first encapsulation component 131 is fixedly connected to the fixing structure 101. Figure 24This is a schematic diagram showing the structure in which the second encapsulation component 132 is fixedly connected to the first rotating component 120. Figure 25 This is a schematic diagram showing the structure where the third encapsulation 133 is fixedly connected to the first sliding member 122. The first encapsulation 131 is fixedly connected to the fixed structure 101 by a threaded connection. The second encapsulation 132 is fixedly connected to the first rotating member 120 by welding. The third encapsulation 133 is fixedly connected to the first sliding member 122 by welding.

[0094] The first encapsulation component 131 is fixedly connected to the fixed structure 101 by a threaded connection, including by bolts 109, studs, or screws. The second encapsulation component 132 is fixedly connected to the first rotating component 120 by welding, including by butt welding, pressure welding, spot welding, or seam welding. The third encapsulation component 133 is fixedly connected to the first sliding component 122 by welding, including by butt welding, pressure welding, spot welding, or seam welding.

[0095] Since the first package 131 is fixedly connected to the fixed structure 101, and the first package 131 does not move during the switching between the flattened and folded states of the rotating shaft assembly 10, the threaded connection between the first package 131 and the fixed structure 101 reduces the difficulty of fixing the first package 131 to one end of the fixed structure 101 when the size of the rotating shaft assembly 10 is small, without affecting the close proximity of the first package 131 and the second package 132 in the flattened and folded states. Furthermore, the threaded connection between the first package 131 and the fixed structure 101 also helps reduce the difficulty of disassembling the first package 131 from the fixed structure 101 during maintenance.

[0096] Since the second package 132 is fixedly connected to the first rotating member 120, and the second package 132 moves during the switching process between the first rotating shaft mechanism 102 and the flattened state, fixing the second package 132 and the first rotating member 120 by welding can reduce the shaking caused by the assembly gap between the second package 132 and the first rotating member 120, ensuring the close proximity of the second package 132 and the first package 131 in the flattened and closed states. Since the third package 133 is fixedly connected to the first sliding member 122, and the third package 133 moves during the switching process between the first rotating shaft mechanism 102 and the flattened and closed states, fixing the third package 133 and the first sliding member 122 by welding can reduce the shaking caused by the assembly gap between the third package 133 and the first sliding member 122, ensuring the close proximity of the third package 133 and the second package 132 in the flattened and closed states.

[0097] Optional, such as Figure 26 As shown, Figure 26 for Figure 23 The diagram shows a partially enlarged view of region E in the rotating shaft assembly 10. The fixing structure 101 includes a base 110 and a first cover 112 that are stacked and fixedly connected. One of the base 110 and the first cover 112 has a countersunk hole 1101, and the other has a threaded hole. The first encapsulation member 131 has a through hole. The rotating shaft assembly 10 also includes a bolt 109, one end of which is located in the countersunk hole 1101, and the other end passes through the through hole and mates with the threaded hole.

[0098] The base 110 and the first cover member 112 are stacked along the thickness direction of the fixing structure 101. In other words, the first cover member 112 covers the back side of the base 110, that is, the side of the base 110 away from the flexible display screen 200. In one possible embodiment, the base 110 has a countersunk hole 1101, and the first cover member 112 has a threaded hole corresponding to the countersunk hole 1101 of the base 110, the threaded hole not penetrating the first cover member 112. In another possible embodiment, the base 110 has a threaded hole, and the first cover member 112 has a countersunk hole 1101 corresponding to the countersunk hole 1101 of the base 110, the threaded hole not penetrating the base 110. The head of the bolt 109 is received in the countersunk hole 1101, and the shank of the bolt 109 is received in the threaded hole. The shank of the bolt 109 has threads, the shape of which includes, but is not limited to, a triangle, a rectangle, a trapezoid, or a sawtooth shape.

[0099] In this embodiment, while the first encapsulation component 131 and the fixing structure 101 are fixedly connected by a threaded connection, the two ends of the bolt 109 do not protrude from the base 110 and the first cover component 112. This ensures the support effect of the base 110 on the flexible display screen 200 and the appearance effect of the surface of the first cover component 112 facing away from the base 110.

[0100] Optional, please refer to Figure 27 and Figure 28 , Figure 27 for Figure 24 A partially enlarged schematic diagram of region F in the rotating shaft assembly 10 shown. Figure 28 for Figure 25 The diagram shows a partially enlarged view of region G in the rotating shaft assembly 10. One of the second encapsulation member 132 and the first rotating member 120 has a first overlapping portion 1320, which overlaps with the other of the two components. The second encapsulation member 132 and the first rotating member 120 are fixedly connected by spot welding and / or seam welding at the first overlapping portion 1320. And / or, one of the third encapsulation member 133 and the first sliding member 122 has a second overlapping portion 1330, which overlaps with the other of the two components. The third encapsulation member 133 and the first sliding member 122 are fixedly connected by spot welding and / or seam welding at the second overlapping portion 1330.

[0101] In one possible embodiment, the second encapsulation 132 has a first overlapping portion 1320, which overlaps the end of the first rotating member 120. The second encapsulation 132 and the first rotating member 120 are fixedly connected by spot welding or seam welding at the first overlapping portion 1320. The third encapsulation 133 has a second overlapping portion 1330, which overlaps the end of the first sliding member 122. The second encapsulation 132 and the first sliding member 122 are fixedly connected by spot welding or seam welding at the second overlapping portion 1330. To reduce the impact of the first overlapping portion 1320 on the first rotating member 120's support of the flexible display screen 200, the first overlapping portion 1320 can overlap the back side of the first rotating member 120, that is, the side of the first rotating member 120 facing away from the flexible display screen 200. In order to reduce the impact of the second overlapping portion 1330 on the first sliding member 122 supporting the flexible display screen 200, the second overlapping portion 1330 can overlap the back side of the first sliding member 122, that is, overlap the side of the first sliding member 122 away from the flexible display screen 200.

[0102] By having one of the second package 132 and the first rotating member 120 have a first overlapping portion 1320, the first overlapping portion 1320 overlaps with the other of the second package 132 and the first rotating member 120, and the second package 132 and the first rotating member 120 are fixedly connected by spot welding and / or seam welding at the first overlapping portion 1320, the difficulty of disassembling the second package 132 and the first rotating member 120 during maintenance can be reduced while achieving a fixed connection between the second package 132 and the first rotating member 120 by welding. By providing a second overlapping portion 1330 to one of the third package 133 and the first slider 122, and having the second overlapping portion 1330 overlap the other of the third package 133 and the first slider 122, the third package 133 and the first slider 122 are fixedly connected by spot welding and / or seam welding at the second overlapping portion 1330. While achieving a fixed connection between the third package 133 and the first slider 122 by welding, the difficulty of disassembling the third package 133 and the first slider 122 during maintenance can be reduced.

[0103] Optional, please refer to Figure 27 and Figure 28 One of the second encapsulation member 132 and the first rotating member 120 has a first positioning post 1321, and the other of the second encapsulation member 132 and the first rotating member 120 has a first positioning hole 1201, with the first positioning post 1321 passing through the first positioning hole 1201; and / or, one of the third encapsulation member 133 and the first sliding member 122 has a second positioning post 1331, and the other of the third encapsulation member 133 and the first sliding member 122 has a second positioning hole 1221, with the second positioning post 1331 passing through the second positioning hole 1221.

[0104] In one possible embodiment, the second encapsulation member 132 has a first positioning post 1321, and the first rotating member 120 has a first positioning hole 1201, with the first positioning post 1321 passing through the first positioning hole 1201. The first positioning hole 1201 can be a through hole or a blind hole. In this embodiment, the first positioning hole 1201 is a through hole as an example. The first positioning post 1321 is disposed on the first overlapping portion 1320, passes through the back side of the first rotating member 120 and into the first positioning hole 1201, and does not protrude from the surface of the first rotating member 120 facing the flexible display screen 200. The third encapsulation member 133 has a second positioning post 1331, and the first sliding member 122 has a second positioning hole 1221, with the second positioning post 1331 passing through the second positioning hole 1221. The second positioning hole 1221 can be a through hole or a blind hole. In this embodiment, the second positioning hole 1221 is a through hole as an example. The second positioning post 1331 is disposed on the second overlapping part 1330, passes through the back side of the first sliding member 122 and is inserted into the second positioning hole 1221, and does not protrude from the surface of the first sliding member 122 facing the flexible display screen 200.

[0105] By providing a first positioning post 1321 to one of the second package 132 and the first rotating member 120, and a first positioning hole 1201 to the other of the second package 132 and the first rotating member 120, the first positioning post 1321 passes through the first positioning hole 1201. This allows for a limiting effect between the second package 132 and the first rotating member 120, thereby improving the connection accuracy between the second package 132 and the first rotating member 120. By providing a second positioning post 1331 to one of the third package 133 and the first slider 122, and a second positioning hole 1221 to the other of the third package 133 and the first slider 122, the second positioning post 1331 passes through the second positioning hole 1221. This allows for a limiting effect between the third package 133 and the first slider 122, thereby improving the connection accuracy between the third package 133 and the first slider 122.

[0106] In one possible embodiment, please refer to Figures 29 to 33 , Figure 29 for Figure 17 The side view of the rotating shaft assembly 10 in its flattened state is shown. Figure 30 for Figure 20 The side view of the rotating shaft assembly 10 in the combined state is shown. Figure 31 for Figure 29 A schematic diagram of the structure of the first package 131. Figure 32 for Figure 29 A schematic diagram of the structure of the second package 132. Figure 33for Figure 29 A schematic diagram of the structure of the third encapsulation component 133. The first encapsulation component 131 includes a first encapsulation part 1311 and a second encapsulation part 1312 disposed on one side of the first encapsulation part 1311. The second encapsulation component 132 includes a third encapsulation part 1322 and a fourth encapsulation part 1323 disposed on one side of the third encapsulation part 1322. When the first rotating shaft mechanism 102 is in the flattened state, the first encapsulation part 1311, the second encapsulation part 1312, the third encapsulation part 1322, the fourth encapsulation part 1323 and the third encapsulation component 133 are sequentially adjacent. When the first rotating shaft mechanism 102 is in the merged state, the third encapsulation part 1322 overlaps with the second encapsulation part 1312, and the third encapsulation component 133 overlaps with the fourth encapsulation part 1323, and the first encapsulation part 1311, the third encapsulation part 1322 and the third encapsulation component 133 are sequentially adjacent.

[0107] The first encapsulation part 1311 and the second encapsulation part 1312 are integrally connected. The third encapsulation part 1322 and the fourth encapsulation part 1323 are integrally connected. The first overlapping part 1320 and the third encapsulation part 1322 are integrally connected. Optionally, when the first rotating shaft mechanism 102 is in the merged state, the third encapsulation part 1322 is located on the side of the second encapsulation part 1312 away from the first rotating shaft mechanism 102. At this time, the second encapsulation part 1312 is located inside the second encapsulation member 132 and is not visible from the outside of the rotating shaft assembly 10. When the first rotating shaft mechanism 102 is in the merged state, the third encapsulation member 133 is located on the side of the fourth encapsulation part 1323 away from the first rotating shaft mechanism 102. At this time, the fourth encapsulation part 1323 is located inside the third encapsulation member 133 and is not visible from the outside of the rotating shaft assembly 10.

[0108] In this embodiment, when the first rotating shaft mechanism 102 is in a flattened state, and the second encapsulation part 1312 and the third encapsulation part 1322 are adjacent to each other, the second encapsulation part 1312 and the third encapsulation part 1322 are misaligned along the axial direction of the rotating shaft assembly 10, and form an adjacent effect along the radial direction of the rotating shaft assembly 10. When the first rotating shaft mechanism 102 is in a flattened state, and the fourth encapsulation part 1323 and the third encapsulation part 133 are adjacent to each other, the fourth encapsulation part 1323 and the third encapsulation part 133 are misaligned along the axial direction of the rotating shaft assembly 10, and form an adjacent effect along the radial direction of the rotating shaft assembly 10. Thus, during the unfolding and folding process of the first rotating shaft mechanism 102, the third encapsulation part 1322 moves outside the second encapsulation part 1312, and the gap between the second encapsulation part 132 and the first encapsulation part 1312 does not increase; similarly, the third encapsulation part 133 moves outside the fourth encapsulation part 1323, and the gap between the third encapsulation part 133 and the second encapsulation part 132 does not increase.

[0109] By making the first encapsulation component 131 include a first encapsulation portion 1311 and a second encapsulation portion 1312 disposed on one side of the first encapsulation portion 1311, and the second encapsulation component 132 include a third encapsulation portion 1322 and a fourth encapsulation portion 1323 disposed on one side of the third encapsulation portion 1322, when the first rotating shaft mechanism 102 is in the flattened state, the first encapsulation portion 1311, the second encapsulation portion 1312, the third encapsulation portion 1322, the fourth encapsulation portion 1323 and the third encapsulation component 133 are sequentially adjacent to each other. When the first rotating shaft mechanism 102 is in the folded state, the third encapsulation portion 1322 overlaps with the second encapsulation portion 1312, and the third encapsulation component 133 overlaps with the fourth encapsulation portion 1323, and the first encapsulation portion 1311, the third encapsulation portion 1322 and the third encapsulation component 133 are sequentially adjacent to each other, the encapsulation effect of the encapsulation structure 103 can be improved during the unfolding and folding process of the first rotating shaft mechanism 102.

[0110] The first package 131 further includes a first connecting portion 1313, which is located on the side of the first package 1311 facing the fixed structure 101 and is fixedly connected to the fixed structure 101. The second package 132 further includes a second connecting portion 1324, which is located on the side of the third package 1322 facing the first rotating member 120 and is fixedly connected to the first rotating member 120. A first hollow area 1325 is formed between the second connecting portion 1324 and the third package 1322. The third package 133 includes a fifth package 1332 and a third connecting portion 1333, which is located on the side of the fifth package 1332 facing the first sliding member 122 and is fixedly connected to the first sliding member 122. A second hollow area 1334 is formed between the third connecting portion 1333 and the fifth package 1332.

[0111] In an embodiment where the first package 131 and the fixed structure 101 are fixedly connected by a threaded connection, the first connecting portion 1313 includes the through hole described in the above embodiment. In an embodiment where the second package 132 and the first rotating member 120 are fixedly connected by welding, the second connecting portion 1324 includes the first overlapping portion 1320 described in the above embodiment. In an embodiment where the third package 133 and the first sliding member 122 are fixedly connected by welding, the third connecting portion 1333 includes the second overlapping portion 1330 described in the above embodiment. The first connecting portion 1313 and the first package 1311 are integrally connected. The second connecting portion 1324 and the third package 1322 are integrally connected. The fifth package 1332 and the third connecting portion 1333 are integrally connected. During the process of the hinge assembly 10 being in a flattened state, a closed state, and switching between the flattened state and the closed state, the first connecting part 1313 is located inside the first encapsulation part 1311 and is not visible when viewed from the outside of the hinge assembly 10. The second connecting part 1324 is located inside the third encapsulation part 1322 and is not visible when viewed from the outside of the hinge assembly 10. The third connecting part 1333 is located inside the fifth encapsulation part 1332 and is not visible when viewed from the outside of the hinge assembly 10.

[0112] In this embodiment, by including a first connecting portion 1313 in the first package 131, the first connecting portion 1313 is disposed on the side of the first package 1311 facing the fixing structure 101. This ensures that while the first package 131 is fixedly connected to the fixing structure 101, the connection point between the first package 131 and the fixing structure 101 is not visible from the outside of the rotating shaft assembly 10. Furthermore, by including a second connecting portion 1324 in the second package 1322, the second connecting portion 1324 is disposed on the third package 1322. On the side facing the first rotating member 120, the second connecting part 1324 is fixedly connected to the first rotating member 120, and a first hollow area 1325 is formed between the second connecting part 1324 and the third encapsulation part 1322. While realizing the fixed connection between the second encapsulation part 132 and the first rotating member 120, and the overlapping arrangement of the third encapsulation part 1322 and the second encapsulation part 1312 in the combined state, it can ensure that the connection between the second encapsulation part 132 and the first rotating member 120 is not visible from the outside of the rotating shaft assembly 10. By including a third connecting portion 1333 in the third encapsulation 1333, the third connecting portion 1333 is disposed on the side of the fifth encapsulation 1332 facing the first slider 122. The third connecting portion 1333 is fixedly connected to the first slider 122, and a second hollow area 1334 is formed between the third connecting portion 1333 and the fifth encapsulation 1332. While achieving the fixed connection between the third encapsulation 133 and the first slider 122, and the overlapping arrangement of the third encapsulation 133 and the fourth encapsulation 1323 in the combined state, it can be ensured that the connection between the third encapsulation 133 and the first slider 122 is not visible from the outside of the rotating shaft assembly 10.

[0113] Further, please refer to Figure 31 and Figure 32 The second encapsulation portion 1312 includes a first sub-encapsulation portion 131a and a second sub-encapsulation portion 131b that are bent and connected together. The first sub-encapsulation portion 131a overlaps with the third encapsulation portion 1322 when the first rotating shaft mechanism 102 is in a combined state, and the second sub-encapsulation portion 131b extends toward the side where the first rotating member 120 is located. The fourth encapsulation portion 1323 includes a third sub-encapsulation portion 132a and a fourth sub-encapsulation portion 132b that are bent and connected together. The third sub-encapsulation portion 132a overlaps with the third encapsulation portion 133 when the first rotating shaft mechanism 102 is in a combined state, and the fourth sub-encapsulation portion 132b extends toward the side where the first sliding member 122 is located.

[0114] The bending angle between the first sub-package portion 131a and the second sub-package portion 131b can be 90° or close to 90°. The bending angle between the third sub-package portion 132a and the fourth sub-package portion 132b can be 90° or close to 90°.

[0115] By including a first sub-encapsulation portion 131a and a second sub-encapsulation portion 131b that are bent and connected together, an encapsulation can be formed between the back side of the first encapsulation member 131 and the first rotating shaft mechanism. By including a fourth encapsulation portion 1323 including a third sub-encapsulation portion 132a and a fourth sub-encapsulation portion 132b that are bent and connected together, an encapsulation can be formed between the back side of the second encapsulation member 132 and the first rotating shaft mechanism. The bottom of the first encapsulation member 131 is the side of the first encapsulation member 131 that faces away from the flexible display screen 200, and the bottom of the second encapsulation member 132 is the side of the second encapsulation member 132 that faces away from the flexible display screen 200.

[0116] In one possible embodiment, the corners of the first package portion 1311, the third package portion 1322, and the fifth package portion 1332 are rounded. Optionally, the first package portion 1311 is generally inverted triangular in shape, and all three corners of the first package portion 1311 are rounded. The third package portion 1322 is generally inverted triangular in shape, and all three corners of the third package portion 1322 are rounded. The fifth package portion 1332 is generally inverted triangular in shape, and all three corners of the fifth package portion 1332 are rounded.

[0117] By making the corners of the first packaging section 1311, the third packaging section 1322, and the fifth packaging section 1332 rounded, the roundness of the packaging structure 103 can be improved, avoiding the formation of sharp corners that would affect user experience.

[0118] Optionally, the gap between the first package 131 and the second package 132 is less than or equal to 5 mm, and the gap between the second package 132 and the third package 133 is less than or equal to 5 mm.

[0119] This application does not limit the specific dimensions of the gap between the first package 131 and the second package 132, or the specific dimensions of the gap between the second package 132 and the third package 133. In one possible embodiment, the gap between the first package 131 and the second package 132 may be greater than or equal to 2 mm and less than or equal to 4 mm; the gap between the second package 132 and the third package 133 may be greater than or equal to 2 mm and less than or equal to 4 mm. The gaps between the first package 131 and the second package 132, and between the second package 132 and the third package 133, may be the same. Specifically, when the first rotating shaft mechanism 102 is in a flattened state, the gap between the first package 131 and the second package 132 is less than or equal to 5 mm, and the gap between the second package 132 and the third package 133 is less than or equal to 5 mm. When the first rotating shaft mechanism 102 is in the merged state, the gap between the first package 131 and the second package 132 is less than or equal to 5 mm, and the gap between the second package 132 and the third package 133 is less than or equal to 5 mm. During the switching process between the flattened state and the merged state, the gap between the first package 131 and the second package 132 is less than or equal to 5 mm, and the gap between the second package 132 and the third package 133 is less than or equal to 5 mm.

[0120] Since the first package 131 and the second package 132, and the second package 132 and the third package 133 can be encapsulated by overlapping, by making the gap between the first package 131 and the second package 132 less than or equal to 5mm, and the gap between the second package 132 and the third package 133 less than or equal to 5mm, it is possible to avoid interference or collision between the second package 132 and the first package 131 during movement, and to avoid interference or collision between the third package 133 and the second package 132 during movement.

[0121] In one possible embodiment, the outer surfaces of the first package 131, the second package 132, and the third package 133 undergo surface treatment. The material of the first package 131 may differ from that of the fixed structure; the material of the second package 132 may differ from that of the first rotating member 120; and the material of the third package 133 may differ from that of the first sliding member 122. The materials of the fixed structure, the first rotating member 120, and the first sliding member 122 include, but are not limited to, aluminum alloy, stainless steel, and carbon fiber. The materials of the first package 131, the second package 132, and the third package 133 include, but are not limited to, stainless steel. Surface treatment of the outer surface of the first package 131 includes, but is not limited to, spraying or deposition treatment. Surface treatment of the outer surface of the second package 132 includes, but is not limited to, spraying or deposition treatment of the outer surface of the first package 131. Surface treatment of the outer surface of the third package 133 includes, but is not limited to, spraying or deposition treatment of the outer surface of the first package 131.

[0122] By surface treating the outer surfaces of the first package 131, the second package 132, and the third package 133, the wear resistance and aesthetic appearance of these packages can be improved. In this application, since the first package 131 is fixedly connected to the fixed structure 101, the second package 132 is fixedly connected to the first rotating member 120, and the third package 133 is fixedly connected to the first sliding member 122, each package can be surface treated individually before being fixedly connected to the fixed structure 101, the first rotating member 120, and the first sliding member 122, respectively. This simplifies the surface treatment process for the outer surfaces of the first package 131, the second package 132, and the third package 133, and reduces the cost of surface treatment for these packages.

[0123] In one possible embodiment, please refer to Figures 34 to 36 , Figure 34 This is a schematic cross-sectional view of the first rotating component 120 in the rotating shaft assembly 10 being rotatably connected to the fixed structure 101. Figure 35 This is a cross-sectional schematic diagram showing the second rotating member 121 in the rotating shaft assembly 10 being rotatably connected to the fixed structure 101, and the second rotating member 121 being slidably connected to the first sliding member 122. Figure 36This is a cross-sectional schematic diagram of the first rotating member 120 and the first sliding member 122 rotatably connected in the rotating shaft assembly 10. The first rotating member 120 is rotatably connected to the fixed structure 101 through the cooperation of an arc block and an arc groove. The second rotating member 121 is rotatably connected to the fixed structure 101 through the cooperation of a rotating shaft and a shaft hole. The first rotating member 120 is rotatably connected to the first sliding member 122. The rotation axis of the second rotating member 121 relative to the fixed structure 101 is parallel to and not collinear with the rotation axis of the first rotating member 120 relative to the fixed structure.

[0124] Optionally, the first rotating member 120 and the first sliding member 122 are rotatably connected by the cooperation of an arc block and an arc groove, or the first rotating member 120 and the first sliding member 122 are rotatably connected by the cooperation of a rotating shaft and a shaft hole. 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.

[0125] In embodiments where the first sliding member 122 is rotatably connected to the first rotating member 120, and the first sliding member 122 is slidably connected to the second rotating member 121, and the first rotating member 120 is rotatably connected to the fixed structure 101 through the cooperation of the arc groove and the arc block, and the second rotating member 121 is connected to the fixed structure 101 through the cooperation of the rotating shaft and the shaft hole, the distance between the first sliding member 122 and the fixed structure 101 can be adjusted. This helps to reduce the creases of 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.

[0126] 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.

[0127] The structure of the first rotating shaft mechanism 102 described in the above embodiments is applicable to the second rotating shaft mechanism 104, the structure of the second package 132 described is applicable to the fourth package 134, the third package 133 described is applicable to the fifth package 135, and the side of the first package 131 adjacent to the second package 132 can be symmetrical to the side of the first package 131 adjacent to the fourth package 134.

[0128] Further, please refer to Figures 34 to 36 The rotating shaft assembly 10 also includes a second cover 105 and a third cover 106. The second cover 105 covers the back side of the first rotating member 120 and the second rotating member 121, and the third cover 106 covers the back side of the third rotating member 140 and the fourth rotating member 141.

[0129] The second cover 105 is disposed between the first rotating shaft mechanism 102 and the first battery cover 202. The second cover 105 covering the back sides of the first rotating member 120 and the second rotating member 121 can be understood as 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. The second cover 105 includes a first cover portion and a first clearance portion. The first clearance portion is closer to the fixed structure than the first cover portion, and the first cover portion is closer to the first housing assembly 20 than the first clearance portion. The first clearance portion is integrally connected to the first cover portion. At least a portion of the first clearance portion is bent relative to the first cover portion. The first clearance portion forms a first clearance space at the rotational connection between the first rotating shaft mechanism 102 and the fixed structure 101. Optionally, the first clearance portion forms a first sub-clearance space 151 at the rotational connection between the first rotating member 120 and the fixed structure 101 and / or the first clearance portion forms a second sub-clearance space 152 at the rotational connection between the second rotating member 121 and the fixed structure 101.

[0130] The third cover 106 is disposed between the second rotating shaft mechanism 104 and the second battery cover 302. The third cover 106 covers the back sides of the third rotating member 140 and the fourth rotating member 141, which can be understood as the third cover 106 covering the side of the third rotating member 140 facing away from the flexible display screen 200, and covering the side of the fourth rotating member 141 facing away from the flexible display screen 200. The third cover 106 includes a second cover portion and a second clearance portion. The second clearance portion is closer to the fixed structure than the second cover portion, and the second cover portion is closer to the first housing assembly 20 than the second clearance portion. The second clearance portion is integrally connected to the second cover portion. At least a portion of the second clearance portion is bent relative to the second cover portion. The second clearance portion forms a second clearance space at the rotational connection between the second rotating shaft mechanism 104 and the fixed structure 101. Optionally, the second clearance portion forms a third sub-clearance space 161 at the rotational connection between the third rotating member 140 and the fixed structure 101, and / or the second clearance portion forms a fourth sub-clearance space 162 at the rotational connection between the fourth rotating member 141 and the fixed structure 101.

[0131] In this embodiment, by providing a second cover 105, a shield can be formed on the back side of the first rotating shaft mechanism 102, preventing the components of the first rotating shaft mechanism 102 from being exposed. The second cover 105 includes a first cover portion and a first clearance portion. At least a portion of the first clearance portion is bent relative to the first cover portion. The first clearance portion forms a first clearance space at the rotational connection between the first rotating shaft mechanism 102 and the fixed structure 101. This can prevent the second cover 105 from interfering with the rotation of the first rotating member 120 and / or the second rotating member 121, and it is beneficial to provide a certain space for the structure at the rotational connection between the first rotating member 120 and / or the second rotating member 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 thickness reduction on one side of the rotating shaft assembly 10.

[0132] By providing a third cover 106, a shield can be formed on the back side of the second rotating shaft mechanism 104, preventing the components of the second rotating shaft mechanism 104 from being exposed. The third cover 106 includes a second cover portion and a second clearance portion. At least a portion of the second clearance portion is bent relative to the second cover portion. The second clearance portion forms a second clearance space at the rotational connection between the second rotating shaft mechanism 104 and the fixed structure 101. This can prevent the third cover 106 from interfering with the rotation of the third rotating member 140 and / or the fourth rotating member 141, and it is beneficial to provide a certain space 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 through the second 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 other side of the rotating shaft assembly 10.

[0133] The second rotating member 121 includes a first gear portion, and the fourth rotating member 141 includes a second gear portion, which meshes with the first gear portion.

[0134] The first gear section may include at least one first gear. The first gear may be a spur gear or a helical gear. The second gear section may include at least one second gear. The second gear may be a spur gear or a helical gear.

[0135] The first rotating shaft mechanism 102 and the second rotating shaft mechanism 104 can be synchronously rotated by the cooperation of the second gear part of the fourth rotating member 141 with the first gear part of the second rotating member 121, thereby reducing the number of parts in the rotating shaft assembly 10.
