Description

Technical Field

[0001] This application relates to the field of electronic products, and more particularly to a foldable electronic device. Background Technology

[0002] With the continuous development of display technology, foldable display terminals are gradually becoming a development trend for future mobile electronic products. When unfolded, foldable electronic devices can achieve a larger display area, enhancing the viewing experience. When folded, they can achieve a smaller size, making them easy for users to carry.

[0003] The foldable electronic device includes at least a flexible screen and a housing. The housing includes two structural components for supporting the flexible screen and a rotating mechanism. The two structural components are connected to both sides of the rotating mechanism. In actual use, the rotating mechanism drives the two structural components to rotate, causing the foldable electronic device to fold or unfold. Traditional dual-screen foldable electronic devices also suffer from a relatively small display area when unfolded. Summary of the Invention

[0004] This application provides a foldable electronic device to improve the problem of a small display area when the foldable electronic device is unfolded.

[0005] To achieve the above objectives, the embodiments of this application provide the following solutions:

[0006] A foldable electronic device is provided, comprising: a flexible screen, a first structural member, a second structural member, and a third structural member. The first, second, and third structural members are located on the same side of the flexible screen. The foldable electronic device further includes a first rotating mechanism and a second rotating mechanism. The first rotating mechanism connects the first and second structural members, and the second rotating mechanism connects the second and third structural members.

[0007] When the foldable electronic device is in the unfolded state, the third structural component, the second structural component, and the first structural component are arranged in sequence along the second direction. The first structural component, the first rotating mechanism, the second structural component, the second rotating mechanism, and the third structural component together constitute a support plane for supporting the flexible screen.

[0008] When the foldable electronic device is in a folded state, the first structural component, the second structural component, and the third structural component are stacked along a third direction, which is perpendicular to the first direction and the second direction, respectively.

[0009] The first rotating mechanism includes a first rotating shaft assembly, a first main shaft, and a second rotating shaft assembly. The first main shaft extends along a first direction, and the second direction is perpendicular to the first direction.

[0010] The first rotating shaft assembly includes a first rotating component, a first rocker arm, and a first fixed frame. The first end of the first rotating component is rotatably connected to the first main shaft, and the second end of the first rotating component is slidably connected to the first fixed frame through a first sliding groove. The second end of the first rotating component can slide relative to the first fixed frame along the extension direction of the first sliding groove. The first end of the first rocker arm is rotatably connected to the first rotating component, and the first end of the first rocker arm is aligned with the first axis of rotation of the first rotating component. The second end of the first rocker arm is slidably connected to the first fixed frame through a first guide groove. The second end of the first rocker arm can slide relative to the first fixed frame along the extension direction of the first guide groove. The first fixed frame is fixedly connected to the first structural component.

[0011] The second rotating shaft assembly includes a second rotating component, a second rocker arm, and a second fixed frame. The first end of the second rotating component is rotatably connected to the first main shaft, and the second end of the second rotating component is slidably connected to the second fixed frame via a second sliding groove. The second end of the second rotating component can slide relative to the second fixed frame along the extension direction of the second sliding groove. The first end of the second rocker arm is rotatably connected to the second rotating component, and the second end of the second rocker arm is slidably connected to the second fixed frame via a second guide groove. The second end of the second rocker arm can slide relative to the second fixed frame along the extension direction of the second guide groove. The second fixed frame is fixedly connected to the second structural component.

[0012] With the above configuration, the first structural component and the second structural component can be connected together via a first rotating mechanism. The first structural component can rotate relative to the first main shaft via a first fixed frame and a first rotating component, and the second structural component can rotate relative to the first main shaft via a second fixed frame and a second rotating component. When the folding electronic device switches between an unfolded state and a folded state, the first structural component can rotate relative to the second structural component via the first rotating mechanism, thereby achieving folding or unfolding of the first structural component relative to the second structural component.

[0013] Furthermore, by providing a first swing arm, when the electronic device is in an unfolded or folded state, a strong constraint is formed between the first rotating component and the first fixed frame via the first swing arm, ensuring a relatively stable positional relationship between the first rotating component and the first fixed frame, thus helping to prevent the first rotating component from rotating relative to the first fixed frame. Similarly, by providing a second swing arm, when the electronic device is in an unfolded or folded state, a strong constraint is formed between the second rotating component and the second fixed frame via the second swing arm, ensuring a relatively stable positional relationship between the second rotating component and the second fixed frame, thus helping to prevent the second rotating component from rotating relative to the second fixed frame.

[0014] The second rotating mechanism includes a third rotating shaft assembly, a second main shaft, and a fourth rotating shaft assembly, with the second main shaft extending along a first direction.

[0015] The first end of the third rotating shaft assembly is rotatably connected to the second main shaft, and the second end of the third rotating shaft assembly is fixedly connected to the second structural component; the first end of the fourth rotating shaft assembly is rotatably connected to the second main shaft, and the second end of the fourth rotating shaft assembly is fixedly connected to the third structural component.

[0016] With the above configuration, the third structural component and the second structural component can be connected together via the second rotating mechanism. The second structural component can rotate relative to the second main shaft via the third rotating component, and the third structural component can rotate relative to the second main shaft via the fourth rotating component. When the folding electronic device switches between the unfolded and folded states, the third structural component can rotate relative to the second structural component via the second rotating mechanism, thereby realizing the folding or unfolding of the third structural component relative to the second structural component.

[0017] In summary, by setting the first rotating mechanism, the first structural component can be folded or unfolded relative to the second structural component; by setting the second rotating mechanism, the third structural component can be folded or unfolded relative to the second structural component, so that the foldable electronic device can switch between the unfolded state and the folded state. When the foldable electronic device is in the unfolded state, it is beneficial to increase the display area of ​​the foldable electronic device and improve the user experience.

[0018] In some embodiments, when the foldable electronic device is in a folded state: the first structural member is located between the third structural member and the second structural member, the first rotating mechanism encloses a first accommodating space, a portion of the flexible screen is located within the first accommodating space, the second rotating mechanism encloses a second accommodating space, and a portion of the flexible screen and a portion of the first structural member are located within the second accommodating space.

[0019] With the above configuration, when the foldable electronic device is in the folded state, the flexible screen is located inside the three structural components, and the cross-sectional shape of the flexible screen can be folded into a G-shape. Because the flexible screen is located inside the three structural components, it is prevented from being exposed. The first, second, and third structural components can protect the flexible screen from damage such as scratches or drops, which helps improve the reliability of the flexible screen and enhances the lifespan and sophistication of the foldable electronic device.

[0020] In some embodiments, the second end of the first rocker arm is slidably connected to the first fixed frame via the first guide groove, including: the second end of the first rocker arm and the first fixed frame are slidably connected via the first shaft and the first guide groove; the second end of the first rocker arm includes the first guide groove, and the first fixed frame is connected to the first shaft; or, the first fixed frame includes the first guide groove, and the second end of the first rocker arm is connected to the first shaft; the extension direction of the first shaft is parallel to the first axis.

[0021] The second end of the second swing arm is slidably connected to the second fixed frame via the second guide groove, including: the second end of the second swing arm and the second fixed frame are slidably connected via the second shaft and the second guide groove; the second end of the second swing arm includes the second guide groove, and the second fixed frame is connected to the second shaft; or, the second fixed frame includes the second guide groove, and the second end of the second swing arm is connected to the second shaft; the extension direction of the second shaft is parallel to the second axis.

[0022] In some embodiments, when the foldable electronic device is in the unfolded state, both the first axis and the second axis are parallel to the support plane. This arrangement helps to reduce the space occupied by the first and second axes in the direction perpendicular to the support plane S, thereby reducing the thickness of the first and second pivot assemblies and preventing them from occupying a large amount of space in the thickness direction.

[0023] In some embodiments, both the first axis and the second axis are perpendicular to the first direction. This arrangement helps to reduce the space occupied by the first and second axes in the first direction, and also helps to reduce the dimensions of the first and second pendulum rods in the first direction.

[0024] In some embodiments, when the foldable electronic device is in the unfolded state: in a first direction, the distance between the first end of the first guide groove and the first end of the first swing rod is greater than the distance between the second end of the first guide groove and the first end of the first swing rod; and in a direction perpendicular to the support plane, the distance between the first end of the first guide groove and the support plane is greater than the distance between the second end of the first guide groove and the support plane.

[0025] In the first direction, the distance between the first end of the second guide groove and the first end of the second swing rod is greater than the distance between the second end of the second guide groove and the first end of the second swing rod. In the direction perpendicular to the support plane, the distance between the first end of the second guide groove and the support plane is greater than the distance between the second end of the second guide groove and the support plane.

[0026] In some embodiments, during the transition of the foldable electronic device from an unfolded state to a folded state, the first axis moves relative to the first guide groove in a direction from the first end of the first guide groove to the second end of the first guide groove, and the second axis moves relative to the second guide groove in a direction from the first end of the second guide groove to the second end of the second guide groove.

[0027] During the transition of the foldable electronic device from a folded state to an unfolded state, the first axis moves relative to the first guide groove along the direction from the second end of the first guide groove to the first end of the first guide groove, and the second axis moves relative to the second guide groove along the direction from the second end of the second guide groove to the first end of the second guide groove.

[0028] With the above configuration, during the transition between the unfolded and folded states of the folding electronic device, the first rotating component and the first fixed frame can be connected via the first swing arm, and the positional relationship between the first rotating component and the first fixed frame is relatively stable. Similarly, the second rotating component and the second fixed frame can be connected via the second swing arm, and the positional relationship between the second rotating component and the second fixed frame is also relatively stable.

[0029] In some embodiments, when the foldable electronic device is in the unfolded state: in a second direction, the distance between the third end of the first guide groove and the main shaft is greater than the distance between the fourth end of the first guide groove and the main shaft, and the dimensions of the third end of the first guide groove are equal to the dimensions of the fourth end of the first guide groove. This ensures that the sliding distance of the first shaft relative to the first guide groove is equal everywhere in the extending direction of the first shaft. In the second direction, the distance between the third end of the second guide groove and the main shaft is greater than the distance between the fourth end of the second guide groove and the main shaft, and the dimensions of the third end of the second guide groove are equal to the dimensions of the fourth end of the second guide groove. This ensures that the sliding distance of the second shaft relative to the second guide groove is equal everywhere in the extending direction of the second shaft.

[0030] In some embodiments, the first end of the first rocker arm and the first rotating member are rotatably connected via a third axis, and the first end of the second rocker arm and the second rotating member are rotatably connected via a fourth axis.

[0031] When the foldable electronic device is in the unfolded state, in the thickness direction of the first pivot assembly, the distance between the first axis and the support plane is greater than the distance between the third axis and the support plane. The distance between the first axis and the third axis is the first distance. In the thickness direction of the second pivot assembly, the distance between the second axis and the support plane is greater than the distance between the fourth axis and the support plane. The distance between the second axis and the fourth axis is the second distance.

[0032] During the transition of the foldable electronic device from an unfolded state to a folded state, in the thickness direction of the first pivot assembly, the distance between the first axis and the third axis is less than the first distance, and in the thickness direction of the second pivot assembly, the distance between the second axis and the fourth axis is less than the second distance.

[0033] When the foldable electronic device is in a folded state, in the thickness direction of the first pivot assembly, the distance between the first axis and the third axis is less than a first distance, and in the thickness direction of the second pivot assembly, the distance between the second axis and the fourth axis is less than a second distance.

[0034] With the above settings, during the transition of the foldable electronic device from the unfolded state to the folded state, the space occupied by the first axis and the third axis in the thickness direction of the first rotating assembly is reduced, and the space occupied by the second axis and the fourth axis in the thickness direction of the second rotating assembly is reduced, which is conducive to achieving the thinness and lightness of the foldable electronic device.

[0035] In some embodiments, the second end of the first rotating member is slidably connected to the first fixed frame, including: the second end of the first rotating member and the first fixed frame are slidably connected by a first slider and a first groove, the second end of the first rotating member includes the first slider, and the first fixed frame includes the first groove, or the first fixed frame includes the first slider and the second end of the first rotating member includes the first groove.

[0036] The second end of the second rotating member is slidably connected to the second fixed frame, including: the second end of the second rotating member and the second fixed frame are slidably connected through a second slider and a second slide groove, the second end of the second rotating member includes a second slider, and the second fixed frame includes a second slide groove, or the second fixed frame includes a second slider and the second end of the second rotating member includes a second slide groove.

[0037] In some embodiments, when the foldable electronic device is in the unfolded state: in the second direction, the distance between the first end of the first slide and the main shaft is equal to the distance between the second end of the first slide and the main shaft; and in the direction perpendicular to the support plane, the distance between the first end of the first slide and the support plane is greater than the distance between the second end of the first slide and the support plane.

[0038] In the second direction, the distance between the first end of the second slide and the main shaft is equal to the distance between the second end of the second slide and the main shaft. In the direction perpendicular to the support plane, the distance between the first end of the second slide and the support plane is greater than the distance between the second end of the first slide and the support plane.

[0039] With the above settings, when the foldable electronic device is in the unfolded state: the extension direction of the first slide is perpendicular to the support plane, and the extension direction of the second slide is perpendicular to the support plane.

[0040] In some embodiments, during the transition of the foldable electronic device from an unfolded state to a folded state, the first slider moves relative to the first slide groove in a direction from the second end of the first slide groove to the first end of the first slide groove, and the second slider moves relative to the second slide groove in a direction from the second end of the second slide groove to the first end of the second slide groove. During the transition of the foldable electronic device from a folded state to an unfolded state, the first slider moves relative to the first slide groove in a direction from the first end of the first slide groove to the second end of the first slide groove, and the second slider moves relative to the second slide groove in a direction from the first end of the second slide groove to the second end of the second slide groove.

[0041] With the above configuration, when the first rotating mechanism is in the unfolded state, the first and second fixed frames can form a partial supporting plane S to support the flexible screen. Correspondingly, when the first rotating mechanism is in the folded state, the first and second fixed frames can enclose a partial first accommodating space to accommodate the flexible screen.

[0042] In some embodiments, the first rotating shaft assembly further includes a first support plate, which is slidably connected to the first rotating member and rotatably connected to the first fixed frame. The second rotating shaft assembly further includes a second support plate, which is slidably connected to the second rotating member and rotatably connected to the second fixed frame.

[0043] When the rotating mechanism is in the unfolded state, the first support plate, the first fixed frame, the main shaft, the second support plate, and the second fixed frame together constitute the support plane of the first rotating mechanism. When the foldable electronic device is in the folded state, the distance between the first end of the first support plate and the first end of the second support plate in the third direction is less than the distance between the second end of the first support plate and the second end of the first support plate in the third direction. This arrangement avoids excessive compression of the flexible screen, thereby reducing the stress on the flexible screen and improving its reliability.

[0044] In some embodiments, a first support plate and a first rotating member are slidably connected via a first mating shaft and a third guide groove, the extension direction of the first mating shaft being parallel to a first direction; the first rotating member includes the first mating shaft, and the first support plate includes the third guide groove. A second support plate and a second rotating member are slidably connected via a second mating shaft and a fourth guide groove, the extension direction of the second mating shaft being parallel to the first direction; the second rotating member includes the second mating shaft, and the second support plate includes the fourth guide groove.

[0045] In some embodiments, the third rotating shaft assembly includes a third rotating member and a third fixed frame. A first end of the third rotating shaft assembly is rotatably connected to a second main shaft, including: the first end of the third rotating member is rotatably connected to the second main shaft; a second end of the third rotating member is rotatably connected to a second structural member via a first connecting shaft; and a second end of the third rotating shaft assembly is fixedly connected to the second structural member, including: the third fixed frame is fixedly connected to the second structural member. The fourth rotating shaft assembly includes a fourth rotating member and a fourth fixed frame. A first end of the fourth rotating shaft assembly is rotatably connected to a second main shaft, including: the first end of the fourth rotating member is rotatably connected to the second main shaft; a second end of the fourth rotating member is rotatably connected to a third structural member via a second connecting shaft; and a second end of the fourth rotating shaft assembly is fixedly connected to the third structural member, including: the fourth fixed frame is fixedly connected to the third structural member.

[0046] With the above configuration, the third structural component and the second structural component can be connected together by the second rotating mechanism, and the third structural component can rotate relative to the second structural component through the second rotating mechanism.

[0047] In some embodiments, when the foldable electronic device is in a flat state, the third fixed frame, the third rotating member, the second main shaft, the fourth rotating member, and the fourth fixed frame together constitute the support plane of the second rotating mechanism. This arrangement allows the third fixed frame, the third rotating member, the second main shaft, the fourth rotating member, and the fourth fixed frame to jointly support the flexible screen. When the foldable electronic device is in a folded state, the support surface of the third fixed frame is parallel to the support surface of the fourth fixed frame, and both the support surfaces of the third and fourth fixed frames are perpendicular to a third direction. This arrangement helps to increase the volume of the second accommodating space, avoids excessive compression of the flexible screen, thereby reducing the stress on the flexible screen and improving its reliability.

[0048] In some embodiments, the third rotating shaft assembly includes a third swing arm, a first end of which is rotatably connected to the second main shaft, and a second end of which is slidably connected to the third fixed frame via a third slide groove. The second end of the third swing arm can slide relative to the third fixed frame along the extension direction of the third slide groove, and the extension direction of the third slide groove intersects with the first direction.

[0049] The fourth rotating shaft assembly includes a fourth swing arm. The first end of the fourth swing arm is rotatably connected to the second main shaft, and the second end of the fourth swing arm is slidably connected to the fourth fixed frame through a fourth slide groove. The second end of the fourth swing arm can slide relative to the fourth fixed frame along the extension direction of the fourth slide groove, and the extension direction of the fourth slide groove intersects with the first direction.

[0050] The above settings facilitate the adjustment of the length between the third and fourth fixing frames, ensure that the length of the flexible screen covering the second and third structural components remains unchanged, and mitigate the squeezing or stretching of the flexible screen by the second rotating mechanism.

[0051] In some embodiments, at least a portion of the third fixed frame is located between the third swing arm and the flexible screen, and at least a portion of the fourth fixed frame is located between the fourth swing arm and the flexible screen. This arrangement avoids interference between the third swing arm and the flexible screen when the third swing arm moves relative to the third fixed frame. It also improves the assembly compactness between the third swing arm and the third fixed frame, reducing the size of the second rotating mechanism. Similarly, interference between the fourth swing arm and the flexible screen when the fourth swing arm moves relative to the fourth fixed frame is avoided. This also improves the assembly compactness between the fourth swing arm and the fourth fixed frame, reducing the size of the second rotating mechanism.

[0052] In some embodiments, the first end of the third swing arm includes a fifth concave-convex surface, and the first end of the fourth swing arm includes a sixth concave-convex surface. The second rotation mechanism further includes a second damping slider and a second elastic member. The second elastic member is disposed on the second main shaft along a first direction. The second damping slider is slidably connected to the second main shaft and can slide relative to the second main shaft along the first direction. The first end of the second damping slider contacts the second elastic member, and the second end of the second damping slider includes a seventh concave-convex surface that mates with the fifth concave-convex surface and an eighth concave-convex surface that mates with the sixth concave-convex surface.

[0053] When the second rotating mechanism switches between the unfolded and folded states, the third swing arm rotates relative to the second main shaft, and the fourth swing arm rotates relative to the second main shaft. The second damping slider drives the second elastic element to compress and deform. The elastic restoring force of the second elastic element acts as a damping force.

[0054] In some embodiments, the first end of the third swing arm includes a first helical surface, and the first end of the fourth swing arm includes a second helical surface. The second rotation mechanism further includes a synchronizing slider, which is slidably connected to the second main shaft. The synchronizing slider can slide relative to the second main shaft in a first direction. The synchronizing slider includes a third helical surface that mates with the first helical surface and a fourth helical surface that mates with the second helical surface.

[0055] With the above configuration, when the third swing arm rotates relative to the second main shaft, the synchronous slider slides relative to the second main shaft, thereby driving the fourth swing arm to rotate relative to the second main shaft. Through the cooperation between the helical surfaces, synchronous movement of the third and fourth swing arms is achieved, which in turn achieves synchronous movement of the third and fourth rotating shaft assemblies.

[0056] In some embodiments, the second rotating mechanism includes a third rotating member, a second main shaft, and a fourth rotating member, wherein the second main shaft extends along a first direction; wherein a first end of the third rotating member is rotatably connected to the second main shaft, a second end of the third rotating member is fixedly connected to a second structural member, a first end of the fourth rotating member is rotatably connected to the second main shaft, and a second end of the fourth rotating member is fixedly connected to the third structural member.

[0057] When the foldable electronic device is in the unfolded state, the third rotating component, the second main shaft, and the fourth rotating component together form the support plane of the second rotating mechanism; when the foldable electronic device is in the folded state, the support surface of the third rotating component is parallel to the support surface of the fourth rotating component, and both the support surfaces of the third and fourth rotating components are perpendicular to the third direction.

[0058] With the above configuration, the third structural component and the second structural component can be connected together by the second rotating mechanism, and the third structural component can rotate relative to the second structural component through the second rotating mechanism.

[0105] In the embodiments of this application, the directional indications used to explain the structure and movement of different components, such as up, down, left, right, front, and back, are relative. These indications are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, these directional indications will also change accordingly.

[0106] This application provides a foldable electronic device. The foldable electronic device can be a mobile phone, tablet computer, television, smart wearable products (e.g., smartwatch, smart bracelet), or other terminal products.

[0107] Figure 1 This is a structural diagram of a foldable electronic device in its unfolded state, provided in an embodiment of this application. Figure 2 for Figure 1 A structural diagram of a foldable electronic device after the flexible screen has been removed. Figure 3 This is a structural diagram of a foldable electronic device in a folded state, provided in an embodiment of this application. Figure 4 for Figure 3 The structural diagram of the foldable electronic device along the AA section line.

[0108] The following is combined Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The following is a description of a foldable electronic device 1:

[0109] The foldable electronic device 1 includes a flexible screen 30. The flexible screen 30 can be an active matrix organic light emitting diode (AMOLED) display.

[0110] As a self-emissive display, AMOLED displays do not require a backlight module (BLM). Therefore, when the substrate of an AMOLED display is made of a flexible resin material, such as polyethylene terephthalate (PET), the AMOLED display can be bent.

[0111] In addition, the foldable electronic device 1 also includes a first rotating mechanism 10, a second rotating mechanism 40, a first structural member 21, a second structural member 22, and a third structural member 23 for supporting the flexible screen 30. The first rotating mechanism 10 is connected between the first structural member 21 and the second structural member 22. The second rotating mechanism 40 is connected between the second structural member 22 and the third structural member 23. The first structural member 21, the second structural member 22, and the third structural member 23 support the flexible screen 30, ensuring that the flexible screen 30 remains as flat as possible during use and protecting the non-display surface of the flexible screen 30. The first structural member 21 and the second structural member 22 can rotate relative to the first rotating mechanism 10, and the second structural member 22 and the third structural member 23 can rotate relative to the second rotating mechanism 40.

[0112] This application embodiment only briefly illustrates some of the structures of the first structural member 21, the second structural member 22, and the third structural member 23, and the accompanying drawings are also simplified. This application embodiment does not strictly limit the specific structure of the first structural member 21, the second structural member 22, and the third structural member 23.

[0113] The first structural member 21, the second structural member 22, and the third structural member 23 may each include a mid-frame structure. The space enclosed by the mid-frame structure is used to install and fix other components of the foldable electronic device 1, such as a camera, earphone, earpiece, buttons, and battery. Furthermore, other electronic components may also be provided on the first structural member 21, the second structural member 22, and the third structural member 23. This embodiment of the application does not limit the other electronic components provided on the first structural member 21, the second structural member 22, and the third structural member 23.

[0114] For example, the flexible screen 30 is located on the same side of the first structural member 21, the second structural member 22, and the third structural member 23. A portion of the flexible screen 30 can be fixed to the first structural member 21, the second structural member 22, and the third structural member 23 by an adhesive layer. A portion of the flexible screen 30 can also be fixed to the first rotating mechanism 10 and the second rotating mechanism 40 by an adhesive layer. This adhesive layer can be a thin film layer formed after applying adhesive, and the specific form of the adhesive layer is not limited in this embodiment. For example, the adhesive layer can be an intermittent thin film layer, or it can be a continuous thin film layer.

[0115] like Figure 1 and Figure 2 As shown, when the foldable electronic device 1 is in the unfolded state, the first structural member 21, the second structural member 22, and the third structural member 23 are arranged in sequence. For example, the included angles between the first structural member 21 and the second structural member 22, and between the second structural member 22 and the third structural member 23, can be approximately 180° (understandably, the included angles between the first structural member 21 and the second structural member 22, and between the second structural member 22 and the third structural member 23, are also allowed to have certain deviations, for example, the included angles can be 165°, 177°, or 185°).

[0116] When the folding electronic device 1 is in the unfolded state, both the first rotating mechanism 10 and the second rotating mechanism 40 are in the unfolded state.

[0117] The first structural member 21, the first rotating mechanism 10, the second structural member 22, the second rotating mechanism 40, and the third structural member 23 together form a supporting plane S. The supporting plane S can be used to support the flexible screen 30, improving the flatness of the flexible screen 30 in its unfolded state. Here, "supporting plane S" can be understood as a plane or an approximate plane. The plane can be an absolute surface or an approximate plane. The approximate plane can be a slightly undulating surface, and the acceptable deviation range of the approximate plane can be, for example, within 5%.

[0118] In some embodiments, the flexible screen 30 can be fixed to the first structural member 21, the first rotating mechanism 10, the second structural member 22, the second rotating mechanism 40, and the third structural member 23 by an adhesive layer. The support effect of the first structural member 21, the first rotating mechanism 10, the second structural member 22, the second rotating mechanism 40, and the third structural member 23 on the flexible screen 30 can be adjusted by adjusting the thickness of the adhesive layer so that the first structural member 21, the first rotating mechanism 10, the second structural member 22, the second rotating mechanism 40, and the third structural member 23 together form the support plane S, thereby ensuring that the flexible screen 30 is in its unfolded state when unfolded. In this case, "together forming the supporting plane S" can also be understood as adjusting the thickness of the adhesive layer so that the first structural member 21, the first rotating mechanism 10, the second structural member 22, the second rotating mechanism 40, and the third structural member 23 together form the supporting plane S, thereby ensuring that the flexible screen 30 is in its unfolded state when unfolded.

[0119] When the folding electronic device 1 transitions from an unfolded state to a folded state, the first structural member 21 rotates relative to the second structural member 22 via the first rotating mechanism 10, and the third structural member 23 rotates relative to the second structural member 22 via the second rotating mechanism 40.

[0120] In this embodiment, when the foldable electronic device 1 is in a double-folded state, the first structural member 21, the second structural member 22, and the third structural member 23 can also be in a double-folded state. For example, the first structural member 21 and the second structural member 22 are stacked, and the third structural member 23 and the second structural member 22 are arranged along the second direction Y. In this case, the first rotating mechanism 10 is in a folded state, and the second rotating mechanism 40 is in an unfolded state. As another example, the third structural member 23 and the second structural member 22 are stacked, and the first structural member 21 and the second structural member 22 are arranged along the second direction Y. In this case, the second rotating mechanism 40 is in a folded state, and the first rotating mechanism 10 is in an unfolded state.

[0121] When the foldable electronic device 1 is in a tri-fold state, the first structural component 21, the second structural component 22, and the third structural component 23 can also be in a tri-fold state.

[0122] like Figure 3 and Figure 4As shown, when the foldable electronic device 1 is in a tri-fold state, the first structural member 21, the second structural member 22, and the third structural member 23 are stacked. The angle between the first structural member 21 and the second structural member 22 can be approximately 0° (understandably, a slight deviation is allowed in the angle between the first structural member 21 and the second structural member 22, for example, the angle can be 1°, 3°, or 5°). At this time, the flexible screen 30 located between the first structural member 21 and the second structural member 22 is in a folded state, and the first rotating mechanism 10 is also in a folded state. The angle between the second structural member 22 and the third structural member 23 can be approximately 0° (understandably, a slight deviation is allowed in the angle between the second structural member 22 and the third structural member 23, for example, the angle can be 1°, 3°, or 5°). At this time, the flexible screen 30 located between the second structural member 22 and the third structural member 23 is in a folded state, and the second rotating mechanism 40 is also in a folded state.

[0123] When the foldable electronic device 1 is in a triple-fold state, the first rotating mechanism 10 and the second rotating mechanism 40 are in a folded state. The following explanation only uses the triple-fold state of the foldable electronic device 1 as an example.

[0124] For ease of explanation, the extension direction of the first rotating mechanism 10 is defined as the first direction X, the arrangement direction of the third structural member 23, the second structural member 22 and the first structural member 21 when the foldable electronic device 1 is in the unfolded state is defined as the second direction Y, and the direction perpendicular to the support plane S is defined as the third direction Z; when the foldable electronic device 1 is in the folded state, the first structural member 21, the second structural member 22 and the third structural member 23 are stacked along the third direction Z; the second direction Y is perpendicular to the first direction X, and the third direction Z is perpendicular to the plane containing the first direction X and the second direction Y.

[0125] Figure 5 A partial enlarged view of M1 when the first rotating mechanism is in the deployed state, provided in an embodiment of this application; Figure 6 for Figure 5 Exploded view of part of the first rotating mechanism in the diagram; Figure 7 for Figure 5 Exploded view of the structure of the first rotating mechanism in the diagram; Figure 8 This is a partial enlarged view of M1 when the first rotating mechanism is in a folded state, as provided in an embodiment of this application.

[0126] In the embodiments of this application, reference is made to Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the first rotating mechanism 10 may include a first rotating shaft assembly 200, a first main shaft 100 and a second rotating shaft assembly 300, with the first main shaft 100 extending along a first direction X.

[0127] In this embodiment of the application, the first rotating shaft assembly 200 includes a first rotating member 210, a first fixed frame 230 and a first swing arm 220, and the second rotating shaft assembly 300 includes a second rotating member 310, a second fixed frame 330 and a second swing arm 320.

[0128] For example, in the first rotating shaft assembly 200, the number of the first rotating member 210, the first fixed frame 230, and the first swing arm 220 is not limited. For example, Figure 6 The first rotating shaft assembly 200 may include two first rotating members 210, a first fixed frame 230, and two first swing rods 220. In this embodiment, the structure of the multiple components in the first rotating shaft assembly 200 is not limited; the multiple components only need to have the same motion principle. For example, when there are multiple first rotating members 210, the structures of the multiple first rotating members 210 can be identical, or there can be structural differences between the multiple first rotating members 210.

[0129] Similarly, in the second rotating shaft assembly 300, the number of the second rotating member 310, the second fixed frame 330, and the second swing rod 320 is not limited. Furthermore, this embodiment does not limit the structure of the multiple components in the second rotating shaft assembly 300, as long as the multiple components have the same motion principle.

[0130] The first end 210a of the first rotating component is rotatably connected to the first main shaft 100, and the second end 210b of the first rotating component is slidably connected to the first fixed frame 230. The first end 220a of the first swing arm is rotatably connected to the first rotating component 210, and the second end 220b of the first swing arm is slidably connected to the first fixed frame 230.

[0131] The first end 210a of the first rotating member can be parallel to the first direction X relative to the rotation axis of the first main shaft 100, and the second end 210b of the first rotating member can be slidably connected to the first fixed frame 230. For example, when the first rotating mechanism is in the unfolded state, the first end 210a of the first rotating member can be the left end of the first rotating member 210, and the second end 210b of the first rotating member can be the right end of the first rotating member 210.

[0132] The second end 210b of the first rotating member can be slidably connected to the first fixed frame 230 through the first sliding groove 231, and the second end 210b of the first rotating member can slide relative to the first fixed frame 230 along the extension direction of the first sliding groove 231.

[0133] In this embodiment of the application, when the foldable electronic device is in the unfolded state, the extending direction of the first slide groove 231 may intersect with the support plane S. For example, the extending direction of the first slide groove 231 may intersect with the support plane S at an acute angle, a right angle, or an obtuse angle.

[0134] Wherein, the axis of rotation of the first rocker arm 220 relative to the first rotating member 210 is the first axis (e.g., the first axis). Figure 7 As shown in L1, the second end 220b of the first rocker arm can be slidably connected to the first fixed frame 230 through the first guide groove 224, and the second end 220b of the first rocker arm can slide relative to the first fixed frame 230 along the extending direction of the first guide groove 224. For example, Figure 7 The first guide groove 224 can be located at the second end 220b of the first rocker arm.

[0135] In this embodiment of the application, when the foldable electronic device is in the unfolded state, the extension direction of the first slide 231 intersects with the orthographic projection of the first axis on the support plane S, and the orthographic projection of the first axis on the support plane S also intersects with the orthographic projection of the first direction X on the support plane S.

[0136] This application does not specifically limit the angle between the orthographic projection of the first axis onto the support plane S and the orthographic projection of the extension direction of the first groove 231 onto the support plane S, nor the angle between the orthographic projection of the first axis onto the support plane S and the orthographic projection of the first direction X onto the support plane S. For example, the angle between the orthographic projection of the first axis onto the support plane S and the orthographic projection of the extension direction of the first groove 231 onto the support plane S can be acute, right, or obtuse, and the angle between the orthographic projection of the first axis onto the support plane S and the orthographic projection of the first direction X onto the support plane S can also be acute, right, or obtuse.

[0137] In this embodiment of the application, when the foldable electronic device is in the unfolded state, the extending direction of the first guide groove 224 may intersect with the support plane S. For example, the extending direction of the first guide groove 224 may intersect with the support plane S at an acute angle, a right angle, or an obtuse angle.

[0138] Similarly, the first end 310a of the second rotating member is rotatably connected to the first main shaft 100, and the second end 310b of the second rotating member is slidably connected to the second fixed frame 330. The first end 320a of the second swing arm is rotatably connected to the second rotating member 310, and the second end 320b of the second swing arm is slidably connected to the second fixed frame 330.

[0139] The first end 310a of the second rotating member can be parallel to the first direction X relative to the rotation axis of the first main shaft 100, and the second end 310b of the second rotating member can be slidably connected to the second fixed frame 330. For example, the first end 310a of the second rotating member can be the right end of the second rotating member 310, and the second end 310b of the second rotating member can be the left end of the second rotating member 310.

[0140] The second end 310b of the second rotating member can be slidably connected to the second fixed frame 330 through the second slide groove 331, and the second end 310b of the second rotating member can slide relative to the second fixed frame 330 along the extension direction of the second slide groove 331.

[0141] In this embodiment of the application, when the foldable electronic device is in the unfolded state, the extending direction of the second slide 331 may intersect with the support plane S. For example, the extending direction of the second slide 331 may intersect with the support plane S at an acute angle, a right angle, or an obtuse angle.

[0142] Wherein, the axis of rotation of the second rocker arm 320 relative to the second rotating member 310 is the second axis (e.g., the second axis). Figure 7 As shown in L2, the second end 320b of the second rocker arm can be slidably connected to the second fixed frame 330 through the second guide groove 324, and the second end 320b of the second rocker arm can slide relative to the second fixed frame 330 along the extending direction of the second guide groove 324. For example, Figure 7 The second guide groove 324 can be located at the second end 320b of the second rocker arm.

[0143] In this embodiment of the application, when the foldable electronic device is in the unfolded state, the extension direction of the second slide 331 intersects the orthographic projection of the second axis onto the support plane S, and the orthographic projection of the second axis onto the support plane S also intersects the orthographic projection of the first direction X onto the support plane S.

[0144] This application does not specifically limit the angle between the orthographic projection of the second axis onto the support plane S and the orthographic projection of the extension direction of the second groove 331 onto the support plane S, nor the angle between the orthographic projection of the second axis onto the support plane S and the orthographic projection of the first direction X onto the support plane S. For example, the angle between the orthographic projection of the second axis onto the support plane S and the orthographic projection of the extension direction of the second groove 331 onto the support plane S can be acute, right, or obtuse, and the angle between the orthographic projection of the second axis onto the support plane S and the orthographic projection of the first direction X onto the support plane S can also be acute, right, or obtuse.

[0145] In this embodiment of the application, when the foldable electronic device is in the unfolded state, the extending direction of the second guide groove 324 may intersect with the support plane S. For example, the extending direction of the second guide groove 324 may intersect with the support plane S at an acute angle, a right angle, or an obtuse angle.

[0146] Furthermore, the first fixing bracket 230 and the first structural member 21 can be fixedly connected by threaded fasteners such as bolts. Similarly, the second fixing bracket 330 and the second structural member 22 can be fixedly connected by threaded fasteners such as bolts. Of course, the embodiments of this application do not limit the fixing connection method between the first fixing bracket 230 and the first structural member 21, or between the second fixing bracket 330 and the second structural member 22.

[0147] With the above configuration, the first structural component 21 and the second structural component 22 can be connected together via the first rotating mechanism 10. The first structural component 21 can rotate relative to the first main shaft 100 via the first fixing frame 230 and the first rotating component 210, and the second structural component 22 can rotate relative to the first main shaft 100 via the second fixing frame 330 and the second rotating component 310. When the folding electronic device 1 switches between the unfolded state and the folded state, the first structural component 21 can rotate relative to the second structural component 22 via the first rotating mechanism 10, thereby realizing the folding or unfolding of the first structural component 21 relative to the second structural component 22.

[0148] Furthermore, by providing the first swing arm 220, when the electronic device is in an unfolded or folded state, a strong constraint is formed between the first rotating member 210 and the first fixed frame 230 through the first swing arm 220. The positional relationship between the first rotating member 210 and the first fixed frame 230 is relatively stable, which helps to prevent the first rotating member 210 from rotating relative to the first fixed frame 230. Similarly, by providing the second swing arm 320, when the electronic device is in an unfolded or folded state, a strong constraint is formed between the second rotating member 310 and the second fixed frame 330 through the second swing arm 320. The positional relationship between the second rotating member 310 and the second fixed frame 330 is relatively stable, which helps to prevent the second rotating member 310 from rotating relative to the second fixed frame 330.

[0149] By setting the first swing arm 220 and the second swing arm 320, when the foldable electronic device is in the unfolded or folded state, it is beneficial to prevent the first pivot assembly 200 or the second pivot assembly 300 from rotating relative to the first main shaft 100 when the foldable electronic device is impacted or dropped. This prevents the containment space enclosed by the first pivot assembly 200, the second pivot assembly 300 and the first main shaft 100 from squeezing the flexible screen, which helps to improve the reliability of the flexible screen.

[0150] Figure 9A partial enlarged view of M2 when the second rotating mechanism is in the deployed state, as provided in an embodiment of this application; Figure 10 This is a partial enlarged view of M2 when the second rotating mechanism is in a folded state, as provided in an embodiment of this application.

[0151] In the embodiments of this application, reference is made to Figure 9 as well as Figure 10 The second rotating mechanism 40 includes a third rotating shaft assembly 800, a second main shaft 700, and a fourth rotating shaft assembly 900, with the second main shaft 700 extending along a first direction X.

[0152] The first end 800a of the third rotating shaft assembly is rotatably connected to the second main shaft 700, and the second end 800b of the third rotating shaft assembly is fixedly connected to the second structural member 22. The first end 900a of the fourth rotating shaft assembly is rotatably connected to the second main shaft 700, and the second end 900b of the fourth rotating shaft assembly is fixedly connected to the third structural member 23.

[0153] The second structural component 22 and the third rotating shaft assembly 800 can be fixedly connected by bolts or other threaded fasteners. Similarly, the third structural component 23 and the fourth rotating shaft assembly 900 can be fixedly connected by bolts or other threaded fasteners. Of course, the embodiments of this application do not limit the fixed connection method between the second structural component 22 and the third rotating shaft assembly 800, or between the third structural component 23 and the fourth rotating shaft assembly 900.

[0154] With the above configuration, the third structural member 23 and the second structural member 22 can be connected together by the second rotating mechanism 40. When the folding electronic device 1 switches between the unfolded state and the folded state, the third structural member 23 can rotate relative to the second structural member 22 through the second rotating mechanism 40, thereby realizing the folding or unfolding of the third structural member 23 relative to the second structural member 22.

[0155] In summary, by setting the first rotating mechanism 10, the first structural component 21 can be folded or unfolded relative to the second structural component 22; by setting the second rotating mechanism 40, the third structural component 23 can be folded or unfolded relative to the second structural component 22, so that the foldable electronic device can switch between the unfolded state and the folded state. When the foldable electronic device is in the unfolded state, it is beneficial to increase the display area of ​​the foldable electronic device and improve the user experience.

[0156] In some embodiments, combined with Figure 4As shown, when the foldable electronic device 1 is in a folded state: the first structural member 21 is located between the second structural member 22 and the third structural member 23, the first rotating mechanism 10 encloses the first accommodating space P1, a portion of the flexible screen 30 is located in the first accommodating space P1, the second rotating mechanism 40 encloses the second accommodating space P2, a portion of the flexible screen 30 and a portion of the first structural member 21 are located in the second accommodating space P2.

[0157] For example, in the foldable electronic device 1 of this application embodiment, when transitioning from an unfolded state to a folded state, the first structural member 21 and the second structural member 22 can be folded inward by the first rotating mechanism 10, and then the third structural member 23 and the second structural member 22 can be folded inward by the second rotating mechanism 40. The first accommodating space P1 can be smaller than the second accommodating space P2, so that the second accommodating space P2 can accommodate a portion of the flexible screen 30 and a portion of the first structural member 21.

[0158] With the above configuration, when the foldable electronic device 1 is in the folded state, the flexible screen 30 is located inside the three structural components, and the cross-sectional shape of the flexible screen 30 can be folded into a G-shape. Because the flexible screen 30 is located inside the three structural components, it is prevented from being exposed. The first structural component 21, the second structural component 22, and the third structural component 23 can protect the flexible screen 30, preventing damage (such as scratches or drops), which helps improve the reliability of the flexible screen 30 and enhances the lifespan and sophistication of the foldable electronic device 1.

[0159] Of course, in some embodiments, when the foldable electronic device 1 is in a folded state, the first structural member 21, the second structural member 22, and the third structural member 23 can be arranged in other ways, and correspondingly, the cross-sectional shape of the flexible screen 30 can be folded into other shapes. For example, when the first structural member 21, the second structural member 22, and the third structural member 23 are stacked along the third direction Z, the second structural member 22 can be located between the first structural member 21 and the third structural member 23, and the cross-sectional shape of the flexible screen 30 can be folded into an S-shape.

[0160] With the above settings, when the foldable electronic device 1 is in a folded state, part of the flexible screen 30 can be exposed, so that the user can still use the flexible screen 30 when the foldable electronic device 1 is in a folded state, thus increasing the application scenarios of the foldable electronic device 1.

[0161] The following is for reference. Figures 11 to 26 The structure of the first rotating mechanism 10 will be further explained.

[0162] Figure 11 An exploded view of the structure of a first main shaft provided in an embodiment of this application.

[0163] In some embodiments, refer to Figure 11 The first main shaft 100 may include a first main outer shaft 110 and a first main inner shaft, wherein the first main inner shaft and the first main outer shaft 110 are stacked, and the first main inner shaft is located between the flexible screen 30 and the first main outer shaft 110, and the first main inner shaft is used to support the flexible screen 30. The first main inner shaft may include a first shaft portion 121 and a second shaft portion 122 stacked, wherein the second shaft portion 122 is located between the first shaft portion 121 and the first main outer shaft 110.

[0164] The first shaft portion 121 and the second shaft portion 122 together form a first arc-shaped slide groove 101 and a second arc-shaped slide groove 102. The first arc-shaped slide groove 101 and the second arc-shaped slide groove 102 can be arranged at intervals along the second direction Y, and the central axis of the first arc-shaped slide groove 101 and the central axis of the second arc-shaped slide groove 102 are both parallel to the first direction X.

[0165] Figure 12 An exploded view of the assembly structure of a first rotating member, a second rotating member, and other components provided in an embodiment of this application.

[0166] Correspondingly, combined Figure 12 The first end 210a of the first rotating member may include a first arc-shaped slider 211, which is slidably connected to the first arc-shaped groove 101, so that the first end 210a of the first rotating member and the first main shaft 100 can be rotatably connected through a virtual axis connection. The first end 310a of the second rotating member may include a second arc-shaped slider 311, which is slidably connected to the second arc-shaped groove 102, so that the first end 310a of the second rotating member and the first main shaft 100 can be rotatably connected through a virtual axis connection.

[0167] With the above settings, the rotation axis of the first rotating member 210 relative to the first main shaft 100 and the rotation axis of the second rotating member 310 relative to the first main shaft 100 are both parallel to the first direction X and do not coincide.

[0168] Figure 13 for Figure 12 A cross-sectional view along section line BB when the first rotating mechanism is in the deployed state; Figure 14 for Figure 12 A sectional view along section line BB when the first rotating mechanism is in the folded state.

[0169] Reference Figure 13 and Figure 14As the rotating mechanism transitions from a folded state to an unfolded state, the portion of the first arc-shaped slider 211 located in the first arc-shaped groove 101 gradually increases, and the portion of the second arc-shaped slider 311 located in the second arc-shaped groove 102 gradually increases. Conversely, as the rotating mechanism transitions from an unfolded state to a folded state, the portion of the first arc-shaped slider 211 located in the first arc-shaped groove 101 gradually decreases, and the portion of the second arc-shaped slider 311 located in the second arc-shaped groove 102 gradually decreases.

[0170] In addition, in some embodiments, the first rotating member 210 may also include a first arc-shaped slide groove 101, and the first main shaft 100 may include a first arc-shaped slider 211; the second rotating member 310 may also include a second arc-shaped slide groove 102, and the first main shaft 100 may include a second arc-shaped slider 311.

[0171] Of course, the first rotating member 210 and the first spindle 100 can also be rotatably connected by other virtual axis connection methods, and the second rotating member 310 and the first spindle 100 can also be rotatably connected by other virtual axis connection methods. This application embodiment does not limit this.

[0172] Continue to refer to Figure 12 The second end 210b of the first rotating component and the first fixed frame 230 are slidably connected by a first slider 212 and a first groove 231. The second end 210b of the first rotating component includes the first slider 212, and the first fixed frame 230 includes the first groove 231. The second end 310b of the second rotating component and the second fixed frame 330 are slidably connected by a second slider 312 and a second groove 331. The second end 310b of the second rotating component includes the second slider 312, and the second fixed frame 330 includes the second groove 331.

[0173] With the above configuration, the first fixed frame 230 can slide relative to the first rotating member 210 along the extension direction of the first slide groove 231, and the second fixed frame 330 can slide relative to the second rotating member 310 along the extension direction F3 of the second slide groove 331.

[0174] Continue to refer to Figure 13 When the rotating mechanism is in the unfolded state, in the second direction Y, the distance between the first end 231a of the first slide groove and the first main shaft 100 is equal to the distance between the second end 231b of the first slide groove and the first main shaft 100. In the direction perpendicular to the support plane S, the distance between the first end 231a of the first slide groove and the support plane S is greater than the distance between the second end 231b of the first slide groove and the support plane S.

[0175] For example, Figure 13 and Figure 14In the diagram, F1 can be used to indicate the extension direction of the first slide groove. When the rotating mechanism is in the unfolded state, the extension direction of the first slide groove 231 can be perpendicular to the support plane S. The first slide groove 231 can penetrate the first fixed frame 230. In the cross-section perpendicular to the support plane S, the cross-sectional shape of the first slide groove 231 can be approximately rectangular. The first end 231a of the first slide groove can be the bottom end of the first slide groove 231, and the second end 231b of the first slide groove can be the top end of the first slide groove 231. Correspondingly, the first slider 212 can be a rectangular slider. The first slider 212 can slide within the first slide groove 231 so that the second end 210b of the first rotating member and the first fixed frame 230 are slidably connected.

[0176] Similarly, in the second direction Y, when the first rotating mechanism is in the unfolded state, the distance between the first end 331a of the second slide and the first main shaft 100 is equal to the distance between the second end 331b of the second slide and the first main shaft 100. In the direction perpendicular to the support plane S, the distance between the first end 331a of the second slide and the support plane S is greater than the distance between the second end 331b of the second slide and the support plane S.

[0177] For example, Figure 13 and Figure 14 In the diagram, F3 can be used to indicate the extension direction of the second slide groove. When the rotating mechanism is in the unfolded state, the extension direction of the second slide groove 331 can be perpendicular to the supporting plane S. The second slide groove 331 can penetrate the second fixed frame 330. In the cross-section perpendicular to the supporting plane S, the cross-sectional shape of the second slide groove 331 can be approximately rectangular. The first end 331a of the second slide groove can be the bottom end of the second slide groove 331, and the second end 331b of the second slide groove can be the top end of the second slide groove 331. Correspondingly, the second slider 312 can be a rectangular slider. The second slider 312 can be slidably connected to the second slide groove 331 so that the second end 310b of the second rotating member is slidably connected to the second fixed frame 330.

[0178] Combination Figure 13 and Figure 14 As shown, during the transition from the unfolded state to the folded state, the first slider 212 moves relative to the first slide groove 231 along the direction from the second end 231b of the first slide groove to the first end 231a of the first slide groove, and the second slider 312 moves relative to the second slide groove 331 along the direction from the second end 331b of the second slide groove to the first end 331a of the second slide groove.

[0179] During the transition from the folded state to the unfolded state, the first slider 212 moves relative to the first slide groove 231 in the direction from the first end 231a of the first slide groove to the second end 231b of the first slide groove, and the second slider 312 moves relative to the second slide groove 331 in the direction from the first end 331a of the second slide groove to the second end 331b of the second slide groove.

[0180] With the above configuration, when the first rotating mechanism is in the unfolded state, the first fixing frame 230 and the second fixing frame 330 can form a partial supporting plane S to support the flexible screen 30. Correspondingly, when the first rotating mechanism is in the folded state, the first fixing frame 230 and the second fixing frame 330 can enclose a partial first accommodating space to accommodate the flexible screen 30.

[0181] Furthermore, based on the same inventive concept, in some other embodiments, the first sliding groove may be disposed on the first rotating member 210, and the first slider 212 may be disposed on the first fixed frame 230; the second rotating member 310 may also include a second sliding groove 331, and the second fixed frame 330 may include a second slider 312. Of course, the first rotating member 210 and the first fixed frame 230, and the second rotating member 310 and the second fixed frame 330 may also be slidably connected by other connection methods, and the embodiments of this application do not limit this.

[0182] Figure 15 This application provides a partial structural assembly diagram of a first rotating assembly and a second rotating assembly, as shown in the embodiments of this application. Figure 16 An exploded view of a partial structure of a first rotating assembly and a second rotating assembly provided in an embodiment of this application.

[0183] Reference Figure 15 and Figure 16 As shown, the second end 220b of the first rocker arm is slidably connected to the first fixed frame 230, which may include: the second end 220b of the first rocker arm and the first fixed frame 230 can be slidably connected through the first shaft 410 and the first guide groove 224. Specifically, the second end 220b of the first rocker arm may include the first guide groove 224, and the first fixed frame 230 can be connected to the first shaft 410.

[0184] For example, the first fixing frame 230 may have a mounting hole, and the first shaft 410 may be installed in the mounting hole of the first fixing frame 230. The first shaft 410 may rotate relative to the first fixing frame 230, or the first shaft 410 may be fixedly connected to the first fixing frame 230. With the above configuration, the second end 220b of the first rocker arm may slide relative to the first fixing frame 230 along the extending direction of the first guide groove 224.

[0185] Similarly, the second end 320b of the second rocker arm is slidably connected to the second fixed frame 330, which may include: the second end 320b of the second rocker arm and the second fixed frame 330 can be slidably connected through the second shaft 510 and the second guide groove 324. The second end 320b of the second rocker arm includes the second guide groove 324, and the second fixed frame 330 is connected to the second shaft 510.

[0186] For example, the second fixing frame 330 may also have a mounting hole, and the second shaft 510 may be installed in the mounting hole of the second fixing frame 330. The second shaft 510 may rotate relative to the second fixing frame 330, or the second shaft 510 may be fixedly connected to the second fixing frame 330. With the above configuration, the second end 320b of the second rocker arm may slide relative to the second fixing frame 330 along the extending direction of the second guide groove 324.

[0187] Figure 17 A structural diagram of a first pendulum and a second pendulum provided in an embodiment of this application; Figure 18 This application provides a structural assembly drawing of a first rocker arm and shaft, and a second rocker arm and shaft, according to an embodiment of the present application.

[0188] Reference Figure 17 and Figure 18 As shown, the first guide groove 224 can be approximately strip-shaped, and it can extend through the second end 220b of the first rocker arm. The size of the first guide groove 224 remains unchanged along its extending direction. During the transition of the rotating mechanism from an unfolded state to a folded state, the first shaft 410 can slide relative to the first guide groove 224 along its extension direction. Simultaneously, the first shaft 410 can also rotate relative to the first guide groove 224.

[0189] The second guide groove 324 can be generally strip-shaped, and it can extend through the second end 320b of the second rocker arm. The size of the first guide groove 224 remains unchanged along its extending direction. During the transition from the unfolded state to the folded state of the rotating mechanism, the second shaft 510 can slide relative to the second guide groove 324 along the extending direction F4. Simultaneously, the second shaft 510 can rotate relative to the second guide groove 324.

[0190] Of course, the first swing arm 220 and the first fixed frame 230, the second swing arm 320 and the second fixed frame 330 can also be slidably connected by other connection methods. The specific structure and structural relationship of the first shaft 410, the first guide groove 224, the second shaft 510 and the second guide groove 324 are only illustrative examples of the inventive concept of this application and are not intended to limit the protection scope of this invention. The embodiments of this application do not limit this.

[0191] Figure 19A for Figure 15 A cross-sectional view along the CC section line of the rotating mechanism in its unfolded state; Figure 19B for Figure 15 A cross-sectional view along the CC section line of the rotating mechanism in a folded state. Figure 19A and Figure 19B In this context, F1 can be used to indicate the extension direction of the first groove, and F2 can be used to indicate the extension direction of the first guide groove.

[0192] Combination Figure 19A and Figure 19B As shown, when the rotating mechanism is in the deployed state, the extension direction of the first guide groove 224 can intersect the supporting plane S. In this embodiment, the angle between the extension direction of the first guide groove 224 and the supporting plane S is not specifically limited. Furthermore, when the rotating mechanism is in the deployed state, the orthographic projection of the extension direction of the first guide groove 224 onto the supporting plane S can also be perpendicular to the orthographic projection of the second direction Y onto the supporting plane S.

[0193] Figure 20A for Figure 15 A cross-sectional view along section line DD of the rotating mechanism in its unfolded state; Figure 20B for Figure 15 A cross-sectional view along section line DD of the rotating mechanism in a folded state. Figure 20A and Figure 20B In the diagram, F3 can be used to indicate the extension direction of the second groove, and F4 can be used to indicate the extension direction of the second guide groove.

[0194] Combination Figure 20A and Figure 20B As shown, when the rotating mechanism is in the deployed state, the extension direction of the second guide groove 324 can intersect the supporting plane S. In this embodiment, the angle between the extension direction of the second guide groove 324 and the supporting plane S is not specifically limited. In some embodiments, when the rotating mechanism is in the deployed state, the first fixing frame 230 and the second fixing frame 330 can constitute part of the supporting plane S. Furthermore, when the rotating mechanism is in the deployed state, the orthographic projection of the extension direction of the second guide groove 324 onto the supporting plane S can also be perpendicular to the orthographic projection of the second direction Y onto the supporting plane S.

[0195] Continue to refer to Figure 15 and Figure 16The first end 220a of the first rocker arm is rotatably connected to the first rotating member 210. It may further include: the first end 220a of the first rocker arm and the first rotating member 210 can be rotatably connected via a third shaft 420 and a first mating hole 225. Specifically, the first end 220a of the first rocker arm may include the first mating hole 225, and the third shaft 420 can be connected to the first rotating member 210. The extension direction of the central axis of the third shaft 420 is the first axis.

[0196] For example, the first rotating member may have a first recess 219, and the sidewall of the first recess 219 may be provided with a mounting hole. The first end 220a of the first rocker arm may be installed in the mounting hole of the first rotating member 210. The third shaft 420 may rotate relative to the first rotating member 210, or the third shaft 420 may be fixedly connected to the first rotating member 210. With the above configuration, the first end 220a of the first rocker arm can rotate relative to the first rotating member 210 through the third shaft 420.

[0197] In some embodiments, the first end 320a of the second rocker arm is rotatably connected to the second rotating member 310, and may further include: the first end 320a of the second rocker arm and the second rotating member 310 can be rotatably connected via a fourth shaft 520 and a second mating hole 325. Specifically, the first end 350a of the second rocker arm includes the second mating hole 325, and the fourth shaft 520 is connected to the second rotating member 310. The extension direction of the central axis of the fourth shaft 520 is the second axis.

[0198] For example, the second rotating member may have a second recess 319, the sidewall of which may have a mounting hole. The first end 320a of the second rocker arm may be installed in the mounting hole of the second rotating member 310, and the fourth shaft 520 may rotate relative to the second rotating member 310, or the fourth shaft 520 may be fixedly connected to the second rotating member 310. With the above configuration, the first end 320a of the second rocker arm can rotate relative to the second rotating member 310 via the fourth shaft 520.

[0199] In some embodiments, since the first end 220a of the first rocker arm is connected to the second end 210b of the first rotating member, the first end 220a of the first rocker arm can move relative to the first fixed frame 230 along with the second end 210b of the first rotating member. Similarly, since the first end 320a of the second rocker arm is connected to the second end 310b of the second rotating member, the first end 320a of the second rocker arm can move relative to the second fixed frame 330 along with the second end 310b of the second rotating member.

[0200] Continue to refer to Figure 18 In some embodiments, the extension direction of the first shaft 410 is parallel to the first axis (e.g., for example, ...). Figure 18(L1 in the above configuration). Through the above configuration, in the thickness direction of the first rocker arm 220, it is beneficial to reduce the space occupied by the first rocker arm 220, which facilitates the thinning of the first rotating shaft assembly 200.

[0201] In some embodiments, the extending direction of the second shaft 510 is parallel to the second axis (e.g., ...). Figure 18 (L2 in the above configuration). With the above configuration, the space occupied by the second rocker arm 320 is reduced in the thickness direction, which facilitates the thinning of the second rotating shaft assembly 300.

[0202] Figure 21A for Figure 15 A cross-sectional view along the EE section line of the rotating mechanism in its unfolded state; Figure 21B for Figure 15 A cross-sectional view along the EE section line of the rotating mechanism in the folded state; Figure 22A for Figure 15 A cross-sectional view along section line FF of the rotating mechanism in its unfolded state; Figure 22B for Figure 15 A cross-sectional view along section line FF of the rotating mechanism in a folded state. Figure 22A and Figure 22B In this context, F1 can be used to indicate the extension direction of the first groove, and F3 can be used to indicate the extension direction of the second groove.

[0203] In some embodiments, combined with Figure 21A As shown, when the rotating mechanism is in the unfolded state: the first shaft 410 and the second shaft 510 can both be parallel to the support plane S.

[0204] For example, the distance between the first end 410a of the first shaft and the first main shaft 100 is less than the distance between the second end 410b of the first shaft and the first main shaft 100. The direction from the first end 410a to the second end 410b of the first shaft is the extension direction of the first shaft 410. Similarly, the distance between the first end 510a of the second shaft and the first main shaft 100 is less than the distance between the second end 510b of the second shaft and the first main shaft 100. The direction from the first end 510a to the second end 510b of the second shaft is the extension direction of the second shaft 510.

[0205] With the above arrangement, in the direction perpendicular to the support plane S, it is beneficial to reduce the space occupied by the first shaft 410 and the second shaft 510, which in turn is beneficial to reduce the thickness of the first shaft assembly 200 and the second shaft assembly 300, and avoid the first shaft assembly 200 and the second shaft assembly 300 occupying a large space in the thickness direction.

[0206] Furthermore, referring to Figure 21A and Figure 21BFurthermore, the first axis 410 and the second axis 510 can both be perpendicular to the first direction X. This arrangement helps to reduce the space occupied by the first axis 410 and the second axis 510 in the first direction X, and also helps to reduce the dimensions of the first rocker arm 220 and the second rocker arm 320 in the first direction X.

[0207] In some embodiments, when the rotating mechanism is in the deployed state: both the first axis and the second axis can be parallel to the support plane S. Further, both the first axis and the second axis can also be perpendicular to the first direction X.

[0208] Combination Figure 22A As shown, the third axis 420 and the fourth axis 520 can also be parallel to the support plane S. The distance between the first end 420a of the third axis and the first main axis 100 is less than the distance between the second end 420b of the third axis and the first main axis 100. The direction from the first end 420a to the second end 420b of the third axis is the extension direction of the third axis 420 (which is also the extension direction of the first axis). Similarly, the distance between the first end 520a of the fourth axis and the first main axis 100 is less than the distance between the second end 520b of the fourth axis and the first main axis 100. The direction from the first end 520a to the second end 520b of the fourth axis is the extension direction of the fourth axis 520 (which is also the extension direction of the second axis).

[0209] The above configuration helps to reduce the space occupied by the third axis 420 and the fourth axis 520, which in turn helps to reduce the space occupied by the first rotating shaft assembly 200 and the second rotating shaft assembly 300.

[0210] In some embodiments, refer to Figure 19A As shown, when the foldable electronic device is in the unfolded state: in the first direction X, the distance between the first end 224a of the first guide groove and the first end 220a of the first swing rod can be greater than the distance between the second end 224b of the first guide groove and the first end 220a of the first swing rod; in the direction perpendicular to the support plane S, the distance between the first end 224a of the first guide groove and the support plane S can be greater than the distance between the second end 224b of the first guide groove and the support plane S.

[0211] For example, the first guide groove 224 can be approximately strip-shaped, and the direction from the first end 224a to the second end 224b of the first guide groove is the extension direction F2 of the first guide groove 224. With the above arrangement, the extension direction F2 of the first guide groove 224 can intersect with the supporting plane S, and the extension direction F2 of the first guide groove 224 can also intersect with the first direction X.

[0212] Furthermore, the direction from the first end 224a of the first guide groove to the second end 224b of the first guide groove can approximate the direction from the first end 220a of the first rocker arm to the second end 220b of the first rocker arm, which helps to reduce the space occupied by the first guide groove 224 at the second end 220b of the first rocker arm, and thus helps to save the space occupied by the first rocker arm 220.

[0213] Furthermore, referring to Figure 17 When the first rotating mechanism is in the deployed state: in the second direction Y, the distance between the third end 224c of the first guide groove and the first main shaft 100 is greater than the distance between the fourth end 224d of the first guide groove and the first main shaft 100, and the dimensions of the third end 224c of the first guide groove are equal to the dimensions of the fourth end 224d of the first guide groove. Here, "the dimensions of the third end 224c of the first guide groove" or "the dimensions of the fourth end 224d of the first guide groove" refers to the cross-sectional dimensions perpendicular to the extension direction of the first guide groove 224.

[0214] For example, the size of the first guide groove 224 can be equal everywhere in the direction from the third end 224c of the first guide groove to the fourth end 224d of the first guide groove, so that the sliding distance of the first shaft 410 relative to the first guide groove 224 is equal everywhere in the extension direction of the first shaft 410.

[0215] Similarly, refer to Figure 20A As shown, when the foldable electronic device is in the unfolded state: in the first direction X, the distance between the first end 324a of the second guide groove and the first end 320a of the second swing rod can be greater than the distance between the second end 324b of the second guide groove and the first end 320a of the second swing rod; in the direction perpendicular to the support plane S, the distance between the first end 324a of the second guide groove and the support plane S can be greater than the distance between the second end 324b of the second guide groove and the support plane S.

[0216] For example, the second guide groove 324 can be approximately strip-shaped, and the direction from the first end 324a of the second guide groove to the second end 324b of the second guide groove is the extension direction F4 of the second guide groove 324. With the above arrangement, the extension direction F4 of the second guide groove 324 can intersect with the supporting plane S, and the extension direction F4 of the second guide groove 324 can also intersect with the first direction X.

[0217] Furthermore, the direction from the first end 324a of the second guide groove to the second end 324b of the second guide groove can also approximate the direction from the second end 320b of the second rocker arm to the first end 320a of the second rocker arm. This arrangement helps to reduce the space occupied by the second guide groove 324 at the second end 220b of the second rocker arm, thereby saving space occupied by the second rocker arm 320.

[0218] Furthermore, referring to Figure 17 When the first rotating mechanism is in the deployed state: in the second direction Y, the distance between the third end 324c of the second guide groove and the first main shaft 100 is greater than the distance between the fourth end 324d of the second guide groove and the first main shaft 100. The dimensions of the third end 324c of the second guide groove are equal to the dimensions of the fourth end 324d of the second guide groove. Here, "the dimensions of the third end 324c of the second guide groove" or "the dimensions of the fourth end 324d of the second guide groove" refers to the cross-sectional dimensions perpendicular to the extension direction of the first guide groove 224.

[0219] For example, the size of the second guide groove 324 can be equal everywhere in the direction from the third end 324c of the second guide groove to the fourth end 324d of the second guide groove, so that the sliding distance of the second shaft 510 relative to the second guide groove 324 is equal everywhere in the extension direction of the second shaft 510.

[0220] Combination Figure 21A and Figure 21B As shown, during the transition of the foldable electronic device from an unfolded state to a folded state, the first axis 410 can move relative to the first guide groove 224 in a direction from the first end 224a of the first guide groove to the second end 224b of the first guide groove. Conversely, during the transition of the foldable electronic device from a folded state to an unfolded state, the first axis 410 can move relative to the first guide groove 224 in a direction from the second end 324b of the first guide groove to the first end 224a of the first guide groove.

[0221] Combination Figure 22A and Figure 22B As shown, during the transition of the foldable electronic device from an unfolded state to a folded state, the second axis 510 can move relative to the second guide groove 324 in a direction from the first end 324a of the second guide groove to the second end 324b of the second guide groove. Conversely, during the transition of the foldable electronic device from a folded state to an unfolded state, the second axis 510 can move relative to the second guide groove 324 in a direction from the second end 324b of the second guide groove to the first end 324a of the second guide groove.

[0222] With the above configuration, during the transition between the unfolded and folded states of the folding electronic device, the first rotating component 210 and the first fixed frame 230 can be connected via the first swing arm 220, and the positional relationship between the first rotating component 210 and the first fixed frame 230 is relatively stable. Similarly, the second rotating component 310 and the second fixed frame 330 can be connected via the second swing arm 320, and the positional relationship between the second rotating component 310 and the second fixed frame 330 is relatively stable.

[0223] Of course, in some other embodiments, the shapes of the first guide groove 224 and the second guide groove 324 can also be other shapes, and this application does not specifically limit them. For example, the shapes of the first guide groove 224 and the second guide groove 324 can also include arc shapes.

[0224] Figure 23 This is a structural diagram illustrating the transition between an unfolded state and a folded state of a first and a second pendulum rod, as provided in an embodiment of this application. (Refer to...) Figure 23 In some embodiments, when the foldable electronic device is in the unfolded state, in the thickness direction of the first pivot assembly 200 (i.e., in the direction perpendicular to the support plane S), the distance between the first axis 410 and the support plane S is greater than the distance between the third axis 420 and the support plane S, and the distance between the first axis 410 and the third axis 420 is a first distance D1. In the thickness direction of the second pivot assembly 300 (i.e., in the direction perpendicular to the support plane S), the distance between the second axis 510 and the support plane S is greater than the distance between the fourth axis 520 and the support plane S, and the distance between the second axis 510 and the fourth axis 520 is a second distance D2.

[0225] During the transition between the unfolded and folded states of the foldable electronic device, the distance between the first axis 410 and the third axis 420 in the thickness direction of the first pivot assembly 200 changes, and the distance between the second axis 510 and the fourth axis 520 in the thickness direction of the second pivot assembly 300 changes.

[0226] When the foldable electronic device is in a folded state, in the thickness direction of the first pivot assembly 200, the distance D3 between the first axis 410 and the third axis 420 is less than the first distance D1, and in the thickness direction of the second pivot assembly 300, the distance D4 between the second axis 510 and the fourth axis 520 is less than the second distance D2.

[0227] With the above settings, during the transition of the foldable electronic device from the unfolded state to the folded state, the space occupied by the first axis 410 and the third axis 420 in the thickness direction of the first pivot assembly 200 is reduced, and the space occupied by the second axis 510 and the fourth axis 520 in the thickness direction of the second pivot assembly 300 is reduced, which is conducive to achieving the thinness and lightness of the foldable electronic device.

[0228] Furthermore, when the foldable electronic device is in a folded state, the first axis 410 and the third axis 420 can at least partially overlap in the extension direction of the first main axis, and the second axis 510 and the fourth axis 520 can at least partially overlap in the extension direction of the first main axis. This arrangement helps to reduce the space occupied by the first axis 410 and the third axis 420 in the thickness direction of the first hinge assembly 200, and the space occupied by the second axis 510 and the fourth axis 520 in the thickness direction of the second hinge assembly 300, thus facilitating the thinning and lightening of the foldable electronic device.

[0229] In some examples, when the foldable electronic device is in a folded state, in a reference plane perpendicular to the extension direction of the first main axis, the central axis of the first axis 410 (i.e., the first axis, for example, is...) Figure 23 The orthographic projection of L1 on the reference plane can coincide with the orthographic projection of the central axis of the third axis 420 on the reference plane. Specifically, in the thickness direction of the first pivot assembly 200, the distance D3 between the first axis 410 and the third axis 420 can be 0. Through this configuration, the distance between the first axis 410 and the third axis 420 in the thickness direction of the first pivot assembly 200 always gradually decreases; this distance does not decrease to 0 and then gradually increase again. Therefore, it is beneficial to further reduce the space occupied by the first rocker arm 220 in the thickness direction of the first pivot assembly 200.

[0230] Alternatively, when the foldable electronic device is in a folded state, in a reference plane perpendicular to the extension direction of the first main axis, the central axis of the third axis 420 (i.e., the second axis, for example, is...) Figure 23 The orthographic projection of L2 on the reference plane can be located between the orthographic projection of the central axis of the first axis 410 on the reference plane and the orthographic projection of the flexible screen on the reference plane. The orthographic projection of the central axis of the third axis 420 (i.e. the first axis) on the reference plane can be located on the side of the orthographic projection of the central axis of the first axis 410 on the reference plane that is away from the orthographic projection of the flexible screen on the reference plane.

[0231] Similarly, when the foldable electronic device is in a folded state, the second axis and the fourth axis within the second pivot assembly can be configured in a similar manner, which will not be elaborated upon here.

[0232] Figure 24 This is a partial enlarged view of a first support plate and a second support plate provided in an embodiment of this application.

[0233] Continue to refer to Figure 6 and Figure 24The first rotating shaft assembly 200 may further include a first support plate 240, which is slidably connected to the first rotating member 210, and the first support plate 240 may also be rotatably connected to the first fixed frame 230. The second rotating shaft assembly 300 may further include a second support plate 340, which is slidably connected to the second rotating member 310, and the second support plate 340 may also be rotatably connected to the second fixed frame 330.

[0234] Combination Figure 22A and Figure 22B As shown, when the folding electronic device 1 is in the unfolded state, the first fixing frame 230, the first support plate 240, the first main shaft 100, the second support plate 340 and the second fixing frame 330 can together form the support plane S of the first rotating mechanism 10.

[0235] When the foldable electronic device 1 is in the unfolded state, the first end 340a of the second support plate, the second end 340b of the second support plate, the second end 240b of the first support plate, and the first end 240a of the first support plate are arranged sequentially along the second direction Y. When the foldable electronic device 1 is in the folded state, the distance between the first end 240a of the first support plate and the first end 340a of the second support plate in the third direction Z is less than the distance between the second end 240b of the first support plate and the second end 240b of the first support plate in the third direction Z.

[0236] For example, the first accommodating space P1, jointly enclosed by the first fixing frame 230, the second fixing frame 330, the first support plate 240, the second support plate 340, the first rotating component 210, the second rotating component 310, and the first main shaft 100, allows the flexible screen 30 to be bent into a teardrop shape or a near-teardrop shape. This arrangement avoids excessive compression of the flexible screen 30, thereby reducing its stress and improving its reliability.

[0237] Figure 25A for Figure 8 A cross-sectional view along section line GG of the first rotating mechanism in the unfolded state; Figure 25B for Figure 8 A cross-sectional view along section line GG of the first rotating mechanism in a folded state.

[0238] Combination Figure 7 , Figure 24 , Figure 25A as well as Figure 25B As shown, the first support plate 240 and the first rotating member 210 are slidably connected by a first mating shaft 216 and a third guide groove 213. The extending direction of the first mating shaft 216 is parallel to the first direction X. The first rotating member 210 may include the first mating shaft 216, and the first support plate 240 may include the third guide groove 213.

[0239] The second support plate 340 and the second rotating member 310 can be slidably connected by the second mating shaft 316 and the fourth guide groove 313. The extension direction of the second mating shaft 316 is parallel to the first direction X. The second rotating member 310 may include the second mating shaft 316, and the second support plate 340 may include the fourth guide groove 313.

[0240] In some embodiments, the first mating shaft 216 may be fixedly connected to the first rotating member 210, or the first mating shaft 216 may also be rotatably connected to the first rotating member 210. Similarly, the second mating shaft 316 may be fixedly connected to the second rotating member 310, or the second mating shaft 316 may also be rotatably connected to the second rotating member 310.

[0241] In other embodiments, the first support plate 240 and the first rotating member 210 can be slidably connected via a virtual axis. Similarly, the second support plate 340 and the second rotating member 310 can also be slidably connected in other ways, and this application does not limit this to any particular method.

[0242] The first support plate 240 and the first fixing frame 230 can be rotatably connected via a third arc-shaped slider 232 and a third arc-shaped groove 241, wherein the first support plate 240 may include the third arc-shaped groove 241, and the first fixing frame 230 may include the third arc-shaped slider 232. The second support plate 340 and the second fixing frame 330 can be rotatably connected via a fourth arc-shaped slider 332 and a fourth arc-shaped groove 341, wherein the second support plate 340 may include the fourth arc-shaped groove 341, and the second fixing frame 330 may include the fourth arc-shaped slider 332.

[0243] In other embodiments, the first support plate 240 may include a third arc-shaped slider 232, and the first fixing frame 230 may include a third arc-shaped groove 241. The second support plate 340 may include a fourth arc-shaped slider 332, and the second fixing frame 330 may include a fourth arc-shaped groove 341.

[0244] Continue to refer to Figure 6 In some embodiments, the first rotating shaft assembly 200 may further include a first swing arm 250, the first end 250a of which may be rotatably connected to the first main shaft 100, the rotation axis of the first swing arm 250 relative to the first main shaft 100 being parallel to the first direction X, and the second end 250b of which may be slidably connected to the first fixed frame 230 through a third guide groove 235, the extension direction of the third guide groove 235 intersecting the first direction X.

[0245] For example, the first fixing frame 230 may include a third guide groove 235, the extension direction of the third guide groove 235 may be perpendicular to the extension direction of the first fixing frame 230, and the extension direction of the third guide groove 235 may also be parallel to the support surface of the first fixing frame 230.

[0246] Correspondingly, the second end 250b of the first swing arm may include a third guide block 251, which is slidably connected to the third guide groove 235. With the above configuration, the first swing arm 250 can move relative to the first fixed frame 230, and the sliding direction of the first swing arm 250 relative to the first fixed frame 230 is perpendicular to the length extension direction of the first fixed frame 230.

[0247] Similarly, the second rotating shaft assembly 300 may also include a second swing arm 350, the first end 350a of the second swing arm being rotatably connected to the first main shaft 100, the rotation axis of the second swing arm 350 relative to the first main shaft 100 being parallel to the first direction X, and the second end 350b of the second swing arm being slidably connected to the second fixed frame 330 through a fourth guide groove 335, the extension direction of the fourth guide groove 335 intersecting the first direction X.

[0248] For example, the second fixing frame 330 may include a fourth guide groove 335, the extension direction of the fourth guide groove 335 may be perpendicular to the extension direction of the second fixing frame 330, and the extension direction of the fourth guide groove 335 may also be parallel to the support surface of the second fixing frame 330.

[0249] Correspondingly, the second end 350b of the second swing arm may include a fourth guide block 351, which is slidably connected to the fourth guide groove 335. With the above arrangement, the second swing arm 350 can move relative to the second fixed frame 330, and the sliding direction of the second swing arm 350 relative to the second fixed frame 330 is perpendicular to the length extension direction of the second fixed frame 330.

[0250] During the transition from the unfolded state to the folded state of the first rotating mechanism 10, the first fixed frame 230 slides away from the first main shaft 100 relative to the second end 250b of the first swing arm, and the second fixed frame 330 slides away from the first main shaft 100 relative to the second end 350b of the second swing arm. During the transition from the folded state to the unfolded state of the first rotating mechanism 10, the first fixed frame 230 slides closer to the first main shaft 100 relative to the second end 250b of the first swing arm, and the second fixed frame 330 slides closer to the first main shaft 100 relative to the second end 350b of the second swing arm.

[0251] The above settings facilitate the adjustment of the length between the first fixing frame 230 and the second fixing frame 330, and help ensure that the length of the flexible screen 30 covering the first structural member 21 and the second structural member 22 does not change, thereby improving the phenomenon of the first rotating mechanism 10 squeezing or stretching the flexible screen 30.

[0252] In some embodiments, the first swing arm 250 may be slidably connected to the first support plate 240, and the second swing arm 350 may be slidably connected to the second support plate 340. For example, in some examples, the first support plate 240 and the first swing arm 250 may also be slidably connected via a rotating shaft and a slotted hole. The extending direction of the rotating shaft is parallel to the first direction X. The first support plate 240 may include a slotted hole, and the rotating shaft is also rotatably connected to the first swing arm 250. The rotating shaft passes through the slotted hole, and when the rotating shaft moves along the extending direction of the slotted hole, the first support plate 240 and the first swing arm 250 slide relative to each other.

[0253] For example, in some examples, the first support plate 240 and the first swing arm 250 can also be slidably connected via a pivot and a guide groove, wherein the guide groove can be straight or curved. As another example, the first support plate 240 and the first swing arm 250 can be slidably connected via a virtual axis. The sliding connection between the second support plate 340 and the second swing arm 350 can be similar and will not be described further here.

[0254] Figure 26 Exploded view of the assembly structure of the first and second swing arms with the main shaft provided in the embodiments of this application.

[0255] Combination Figure 6 and Figure 26 As shown, the first main shaft 100 may include a plurality of first mounting shafts 190 arranged sequentially along the second direction Y, wherein the plurality of first mounting shafts 190 all extend along the first direction X. The first end 250a of the first swing arm may be sleeved on a first mounting shaft 190 so that the first end 250a of the first swing arm can be rotatably connected to the first main shaft 100, and the first end 350a of the second swing arm may be sleeved on a first mounting shaft 190 so that the first end 350a of the second swing arm can be rotatably connected to the first main shaft 100.

[0256] Based on the above structure, the first spindle 100 may further include a first elastic element 180 and a first damping slider 170. The first elastic element 180 may be disposed on the first spindle 100 along a first direction X, and the first damping slider 170 may be slidably connected to the first spindle 100, and the first damping slider 170 may slide relative to the first spindle 100 along the first direction X. For example, the first elastic element 180 may include a spring, and the number of springs may be multiple, and the multiple springs may be correspondingly sleeved on multiple first mounting shafts 190.

[0257] Multiple first mounting shafts 190 can be slidably connected to first damping sliders 170. There can be two first damping sliders 170, and these two sliders can be arranged along a first direction X. The first end of a first elastic element 180 is connected to one first damping slider 170, and the second end of the first elastic element 180 is connected to the other first damping slider 170. Alternatively, in some other embodiments, there can be only one first damping slider 170, where the first end of the first elastic element 180 can be connected to the first main shaft 100, and the second end of the first elastic element 180 can be connected to the first damping slider 170.

[0258] The first swing arm 250 and the second swing arm 350 together constitute a swing arm assembly. In an embodiment where there are two first damping sliders 170, the number of swing arm assemblies in the first rotating mechanism 10 can be two, with one swing arm assembly located on the side of a first damping slider 170 away from the first end of the first elastic member 180, and the other swing arm assembly located on the side of a first damping slider 170 away from the second end of the first elastic member 180. The first swing arm 250 in different swing arm assemblies may have structural differences, and similarly, the second swing arm 350 in different swing arm assemblies may have structural differences.

[0259] Of course, the number of swing arm assemblies is not limited in the embodiments of this application. The following description only uses one swing arm assembly and one corresponding damping slider as an example.

[0260] Furthermore, the first end 250a of the first swing arm may include a first concave-convex surface 258, the first damping slider 170 may include a third concave-convex surface 189 that cooperates with the first concave-convex surface 258, the first end 350a of the second swing arm may include a second concave-convex surface 358, and the first damping slider 170 may include a fourth concave-convex surface 188 that cooperates with the third concave-convex surface 189.

[0261] When the first rotating mechanism 10 switches between the unfolded and folded states, the first swing arm 250 rotates relative to the first main shaft 100. Since the first concave-convex surface 258 of the first swing arm 250 engages with the third concave-convex surface 189 of the first damping slider 170, the first swing arm 250 drives the first damping slider 170 to slide relative to the first main shaft 100 along the first direction X. The first damping slider 170 drives the first elastic element 180 to compress and deform. The elastic restoring force of the first elastic element 180 acts as a damping force, thus providing a damping effect when the first swing arm 250 rotates relative to the first main shaft 100.

[0262] Simultaneously, when the first rotating mechanism 10 switches between the unfolded and folded states, the second swing arm 350 rotates relative to the first main shaft 100. Since the second concave-convex surface 358 of the second swing arm 350 engages with the fourth concave-convex surface 188 of the first damping slider 170, the second swing arm 350 drives the first damping slider 170 to slide relative to the first main shaft 100 along the first direction X. The first damping slider 170 drives the first elastic element 180 to compress and deform. The elastic restoring force of the first elastic element 180 acts as a damping force, thus providing a damping effect when the second swing arm 350 rotates relative to the first main shaft 100.

[0263] In some embodiments, the first end 250a of the first swing arm may further include a first gear 259, and the first main shaft 100 may further include a third gear 199 meshing with the first gear 259. The first end 350a of the second swing arm may further include a second gear 359, and the first main shaft 100 may further include a fourth gear 198 meshing with the second gear 359. The third gear 199 also meshes with the fourth gear 198.

[0264] For example, the first gear 259, the second gear 359, the fourth gear 198 and the third gear 199 can be fitted onto the four first mounting shafts 190 of the first spindle 100.

[0265] When the first swing arm 250 rotates relative to the first main shaft 100, the first gear 259 drives the third gear 199 to rotate, which in turn drives the fourth gear 198 to rotate. The fourth gear 198 then drives the second gear 359 to rotate, causing the second swing arm 350 to rotate relative to the first main shaft 100. Through this configuration, the first swing arm 250 rotates relative to the first main shaft 100 while the second swing arm 350 rotates relative to the first main shaft 100, thus achieving synchronous movement of the first and second swing arms 250.

[0266] Of course, in some other embodiments, the first swing arm 250 and the second swing arm 350 can also achieve synchronous movement through other structures, and this application embodiment does not specifically limit this.

[0267] For example, the first spindle 100 may further include a synchronous drive slider, which is slidably connected to the first spindle 100 along a first direction X. The synchronous drive slider may be located between two through holes at the first end 250a of the first swing arm and between two through holes at the first end 350a of the second swing arm. Furthermore, the synchronous drive slider and the first swing arm 250 may each include two cooperating helical surfaces, and the synchronous drive slider and the second swing arm 350 may each include two cooperating helical surfaces.

[0268] With the above configuration, through the cooperation between the spiral surfaces, the first swing arm 250 can rotate relative to the first main shaft 100 while the second swing arm 350 rotates relative to the first main shaft 100, thereby achieving synchronous movement of the first swing arm 250 and the second swing arm 350, and further achieving synchronous movement of the first rotating shaft assembly 200 and the second rotating shaft assembly 300.

[0269] The following reference Figures 27 to 35 and combined Figure 9 and Figure 10 The structure of the second rotating mechanism 40 will be further explained.

[0270] Figure 27 for Figure 9 Exploded view of the second rotating mechanism in the diagram.

[0271] Combination Figure 9 and Figure 27 The third rotating shaft assembly 800 may include a third rotating member 810 and a third fixed frame 830. The first end 800a of the third rotating shaft assembly is rotatably connected to the second main shaft 700, including: the first end 810a of the third rotating member is rotatably connected to the second main shaft 700. The second end 810b of the third rotating member is rotatably connected to the third fixed frame 830 via a first connecting shaft 840. The second end 80b of the third rotating shaft assembly is fixedly connected to the second structural member 22, including: the third fixed frame 830 is fixedly connected to the second structural member 22.

[0272] The fourth rotating shaft assembly 900 may include a fourth rotating member 910 and a fourth fixed frame 930. The first end 900a of the fourth rotating shaft assembly is rotatably connected to the second main shaft 700, including: the first end 910a of the fourth rotating member is rotatably connected to the second main shaft 700, and the second end 910b of the fourth rotating member is rotatably connected to the fourth fixed frame 930 via a second connecting shaft 940. The second end 90b of the fourth rotating shaft assembly is fixedly connected to the third structural member 23, including: the fourth fixed frame 930 is fixedly connected to the third structural member 23.

[0273] For example, when the second rotating mechanism 40 is in the deployed state, the first end 810a of the third rotating member can be the left end of the third rotating member 810, and the second end 810b of the third rotating member can be the right end of the third rotating member 810. The first end 910a of the fourth rotating member can be the right end of the fourth rotating member 910, and the second end 910b of the fourth rotating member can be the left end of the fourth rotating member 910.

[0274] With the above configuration, the third structural member 23 and the second structural member 22 can be connected together by the second rotating mechanism 40, and the third structural member 23 can rotate relative to the second structural member 22 by the second rotating mechanism 40.

[0275] In some embodiments, continue to combine Figure 9 as well as Figure 10 As shown, when the folding electronic device is in the unfolded state, the third fixing frame 830, the third rotating component 810, the second main shaft 700, the fourth rotating component 910, and the fourth fixing frame 930 together constitute the support plane S of the second rotating mechanism 40.

[0276] For example, the third fixing frame 830 and the fourth fixing frame 930 may include a flat plate structure. With the above arrangement, the third fixing frame 830, the third rotating member 810, the second main shaft 700, the fourth rotating member 910, and the fourth fixing frame 930 can work together to support the flexible screen.

[0277] When the foldable electronic device is in a folded state, the support surface of the third fixing frame 830 is parallel to the support surface of the fourth fixing frame 930, and both the support surfaces of the third fixing frame 830 and the fourth fixing frame 930 are perpendicular to the third direction Z.

[0278] For example, in the direction near the second main shaft 700, the distance between the support surfaces of the third fixing frame 830 and the fourth fixing frame 930 along the third direction Z remains unchanged. For example, the flexible screen can be bent into a U-shape within the second accommodating space P2 jointly enclosed by the third fixing frame 830, the third rotating member 810, the second main shaft 700, the fourth rotating member 910, and the fourth fixing frame 930. This arrangement helps to increase the volume of the second accommodating space P2, avoids excessive compression of the flexible screen, thereby reducing the stress on the flexible screen and improving its reliability.

[0279] Figure 28 An exploded view of the structure of a second spindle 700 provided in an embodiment of this application.

[0280] Reference Figure 28 In some embodiments, the second main shaft 700 may include a second main outer shaft 710 and a second main inner shaft, wherein the second main inner shaft and the second main outer shaft 710 are stacked, and the second main inner shaft is located between the flexible screen 30 and the second main outer shaft 710. The second main inner shaft is used to support the flexible screen 30. The second main inner shaft includes a third shaft portion 721 and a fourth shaft portion 722 stacked, and the fourth shaft portion 722 is located between the third shaft portion 721 and the second main outer shaft 710.

[0281] The third shaft portion 721 and the fourth shaft portion 722 together form a fifth arc-shaped slide groove 701 and a sixth arc-shaped slide groove 702. The fifth arc-shaped slide groove 701 and the sixth arc-shaped slide groove 702 can be arranged at intervals along the second direction Y, and the central axis of the fifth arc-shaped slide groove 701 and the central axis of the sixth arc-shaped slide groove 702 are both parallel to the first direction X.

[0282] Figure 29An exploded view of the assembly structure of a third rotating member 810 and a fourth rotating member 910 with other components provided in an embodiment of this application.

[0283] Correspondingly, combined Figure 29 and Figure 9 As shown, the first end 810a of the third rotating member may include a fifth arc-shaped slider 811, which is slidably connected to a fifth arc-shaped groove 701, so that the first end 810a of the third rotating member and the second main shaft 700 can be rotatably connected through a virtual axis connection. The first end 910a of the fourth rotating member may include a sixth arc-shaped slider 911, which is slidably connected to a sixth arc-shaped groove 702, so that the first end 910a of the fourth rotating member and the second main shaft 700 can be rotatably connected through a virtual axis connection. Through the above arrangement, the rotation axis of the third rotating member 810 relative to the second main shaft 700 and the rotation axis of the fourth rotating member 910 relative to the second main shaft 700 are both parallel to the first direction X and do not coincide.

[0284] Figure 30 for Figure 10 A cross-sectional view along section line KK when the second rotating mechanism 40 is in the unfolded state; Figure 31 for Figure 10 A cross-sectional view along section line KK when the second rotating mechanism 40 is in the folded state.

[0285] Reference Figure 30 and Figure 31 As the second rotating mechanism 40 transitions from a folded state to an unfolded state, the portion of the fifth arc-shaped slider 811 located in the fifth arc-shaped groove 701 gradually increases, and the portion of the sixth arc-shaped slider 911 located in the sixth arc-shaped groove 702 gradually increases. Conversely, as the second rotating mechanism 40 transitions from an unfolded state to a folded state, the portion of the fifth arc-shaped slider 811 located in the fifth arc-shaped groove 701 gradually decreases, and the portion of the sixth arc-shaped slider 911 located in the sixth arc-shaped groove 702 gradually decreases.

[0286] In addition, in some embodiments, the third rotating member 810 may also include a fifth arc-shaped slide groove 701, and the second main shaft 700 may include a fifth arc-shaped slider 811; the fourth rotating member 910 may also include a sixth arc-shaped slide groove 702, and the second main shaft 700 may include a sixth arc-shaped slider 911.

[0287] Of course, the third rotating member 810 and the second main shaft 700 can also be rotatably connected through other virtual axis connection methods, and the fourth rotating member 910 and the second main shaft 700 can also be rotatably connected through other virtual axis connection methods. This application embodiment does not limit this.

[0288] Combination Figure 29 , Figure 30 as well as Figure 31 As shown, the third fixing frame 830 may include a first receiving groove 836, the groove wall of which may be provided with a through hole. Correspondingly, the second end 810b of the third rotating member may be disposed within the first receiving groove 836, and the second end 810b of the third rotating member may be provided with a through hole. The first connecting shaft 840 may be disposed within the through hole of the first receiving groove 836 and the through hole of the third rotating member 810, so that the third rotating member 810 and the third fixing frame 830 are rotatably connected.

[0289] Similarly, the fourth fixing frame 930 may include a second receiving groove 936, the wall of which may be provided with a through hole. Correspondingly, the second end 910b of the fourth rotating member may be disposed within the second receiving groove 936, and the second end 910b of the fourth rotating member may also be provided with a through hole. The second connecting shaft 940 may be disposed within the through hole of the second receiving groove 936 and the through hole of the fourth rotating member 910, so that the fourth rotating member 910 and the fourth fixing frame 930 are rotatably connected.

[0290] In addition, combined Figure 30 As shown, when the second rotating mechanism 40 is in the deployed state, the portion of the third rotating member 810 located in the first receiving groove 836 is coplanar with the third fixed frame 830, and the portion of the fourth rotating member 910 located in the second receiving groove 936 is coplanar with the fourth fixed frame 930. This arrangement facilitates the joint support of the flexible screen by the third fixed frame 830, the third rotating member 810, the fourth rotating member 910, and the fourth fixed frame 930.

[0291] Continue to refer to Figure 9 and Figure 27 The third rotating shaft assembly 800 may further include a third swing arm 820, with a first end 820a rotatably connected to the second main shaft 700 and a second end 820b slidably connected to the third fixed frame 830. The fourth rotating shaft assembly 900 includes a fourth swing arm 920, with a first end 920a rotatably connected to the second main shaft 700 and a second end 920b slidably connected to the fourth fixed frame 930.

[0292] Figure 32 This is an exploded view of the assembly structure of a third swing arm 820 and a third fixed frame 830, and a fourth swing arm 920 and a fourth fixed frame 930, provided as an embodiment of this application, from another perspective. This perspective can be the viewpoint observed from the direction of the main axis towards the flexible screen.

[0293] Reference Figure 32As shown, the second end 820b of the third swing arm is also slidably connected to the third fixed frame 830 through the third slide groove 835. The second end 820b of the third swing arm can slide relative to the third fixed frame 830 along the extension direction of the third slide groove 835. The extension direction of the third slide groove 835 intersects with the first direction X.

[0294] The third fixing frame 830 may include a third slide groove 835. For example, the extension direction of the third slide groove 835 may be perpendicular to the extension direction of the third fixing frame 830, and the extension direction of the third slide groove 835 may also be parallel to the support surface of the third fixing frame 830. Of course, the extension direction of the third slide groove 835 may also be other directions, and this embodiment does not limit this.

[0295] Correspondingly, the second end 820b of the third swing arm may include a third slider 825, which is slidably connected to the third slide groove 835. With the above configuration, the third swing arm 820 can move relative to the third fixed frame 830, and the sliding direction of the third swing arm 820 relative to the third fixed frame 830 is perpendicular to the length extension direction of the third fixed frame 830.

[0296] In some embodiments, at least a portion of the third fixing frame 830 may be located between the third swing arm 820 and the flexible screen. For example, the third slide groove 835 may be disposed on the side of the third fixing frame 830 facing away from the flexible screen, so that the second end 820b of the third swing arm can be located on the side of the third fixing frame 830 facing away from the flexible screen. This arrangement avoids interference between the third swing arm 820 and the flexible screen when the third fixing frame 830 moves relative to it. It also improves the assembly compactness between the third swing arm 820 and the third fixing frame 830, reducing the size of the second rotating mechanism 40.

[0297] Similarly, the second end 920b of the fourth swing arm and the fourth fixed frame 930 can be slidably connected through the fourth slide groove 935. The second end 920b of the fourth swing arm can slide relative to the fourth fixed frame 930 along the extension direction of the fourth slide groove 935. The extension direction of the fourth slide groove 935 intersects with the first direction X.

[0298] The fourth fixing frame 930 may include a fourth sliding groove 935. For example, the extending direction of the fourth sliding groove 935 may be perpendicular to the extending direction of the fourth fixing frame 930, and the extending direction of the fourth sliding groove 935 may also be parallel to the supporting surface of the fourth fixing frame 930. Of course, the extending direction of the fourth sliding groove 935 may also be other directions, and this embodiment does not limit this.

[0299] Accordingly, the second end 920b of the fourth swing arm may include a fourth slider 925, which is slidably connected to the fourth slide groove 935. With the above configuration, the fourth swing arm 920 can move relative to the fourth fixed frame 930, and the sliding direction of the fourth swing arm 920 relative to the fourth fixed frame 930 is perpendicular to the length extension direction of the fourth fixed frame 930.

[0300] In some embodiments, at least a portion of the fourth fixing frame 930 may be located between the fourth swing arm 920 and the flexible screen. For example, the fourth slide groove 935 may be disposed on the side of the fourth fixing frame 930 facing away from the flexible screen, so that the second end 920b of the fourth swing arm can be located on the side of the fourth fixing frame 930 facing away from the flexible screen. This arrangement avoids interference between the fourth swing arm 920 and the flexible screen when the fourth fixing frame 930 moves relative to it. It also improves the assembly compactness between the fourth swing arm 920 and the fourth fixing frame 930, reducing the size of the second rotating mechanism 40.

[0301] Figure 33 for Figure 10 A cross-sectional view along the RR section line when the second rotating mechanism 40 is in the unfolded state; Figure 34 for Figure 10 A cross-sectional view along the RR section line when the second rotating mechanism 40 is in the folded state.

[0302] Combination Figure 33 and Figure 34 As shown, during the transition from the unfolded state to the folded state of the second rotating mechanism 40, the third fixed frame 830 slides away from the second main shaft 700 relative to the second end 820b of the third swing arm, and the fourth fixed frame 930 slides away from the second main shaft 700 relative to the second end 920b of the fourth swing arm. During the transition from the folded state to the unfolded state of the second rotating mechanism 40, the third fixed frame 830 slides closer to the second main shaft 700 relative to the second end 820b of the third swing arm, and the fourth fixed frame 930 slides closer to the second main shaft 700 relative to the second end 920b of the fourth swing arm.

[0303] The above settings facilitate the adjustment of the length between the third fixing frame 830 and the fourth fixing frame 930, ensure that the length of the flexible screen covering the second and third structural components remains unchanged, and improve the phenomenon of the second rotating mechanism 40 squeezing or stretching the flexible screen.

[0304] Figure 35 Exploded view of the assembly structure of the third swing arm 820 and the fourth swing arm 920 with the second main shaft 700, as provided in the embodiments of this application.

[0305] Reference Figure 35As shown, the second main shaft 700 may include a plurality of second mounting shafts 760 arranged sequentially along a second direction, wherein the plurality of second mounting shafts 760 extend along a first direction X. The first end 820a of the third swing arm may be sleeved on a second mounting shaft 760 so that the first end 820a of the third swing arm can be rotatably connected to the third main shaft, and the first end 920a of the fourth swing arm may be sleeved on a second mounting shaft 760 so that the first end 92a of the fourth swing arm can be rotatably connected to the second main shaft 700.

[0306] Based on the above structure, the second spindle 700 may further include a second elastic element 770 and a second damping slider 780. The second elastic element 770 may be disposed on the second spindle 700 along the first direction X, and the second damping slider 780 may be slidably connected to the second spindle 700, and may slide relative to the second spindle 700 along the first direction X. For example, the second elastic element 770 may include a spring, and the number of springs may be multiple, with each spring correspondingly sleeved on a multiple second mounting shaft 760.

[0307] Multiple second mounting shafts 760 can be slidably connected to the second damping sliders 780. There can be multiple second damping sliders 780, and these sliders can be arranged at intervals along a first direction X. The first end of the second elastic element 770 is connected to one second damping slider 780, and the second end of the second elastic element 770 is connected to another second damping slider 780. Alternatively, in some other embodiments, there can be only one second damping slider 780, where the first end of the second elastic element 770 can be connected to the second main shaft 700, and the second end of the second elastic element 770 can be connected to the second damping slider 780.

[0308] The third swing arm 820 and the fourth swing arm 920 together constitute a swing arm assembly. In embodiments where there are multiple second damping sliders 780, the second rotating mechanism 40 can have two swing arm assemblies. One swing arm assembly is located on the side of a second damping slider 780 opposite to the first end of the second elastic member 770, and the other swing arm assembly is located on the side of a second damping slider 780 opposite to the second end of the second elastic member 770. The third swing arm 820 in different swing arm assemblies may have structural differences, and similarly, the fourth swing arm 920 in different swing arm assemblies may have structural differences.

[0309] Of course, the number of swing arm assemblies is not limited in the embodiments of this application. The following description only uses one swing arm assembly and one corresponding damping slider as an example.

[0310] Furthermore, the first end 820a of the third swing arm may include a fifth concave-convex surface 822, the second damping slider 780 may include a seventh concave-convex surface 789 that cooperates with the fifth concave-convex surface 822, the first end 920a of the fourth swing arm may include a sixth concave-convex surface 922, and the second damping slider 780 may include an eighth concave-convex surface 788 that cooperates with the sixth concave-convex surface 922.

[0311] For example, the second elastic element 770 contacts the first end of the second damping slider 780, and the seventh concave-convex surface 789 and the eighth concave-convex surface 788 may be located at the second end of the second damping slider 780.

[0312] When the second rotating mechanism 40 switches between the unfolded and folded states, the third swing arm 820 rotates relative to the second main shaft 700. Since the fifth concave-convex surface 822 of the third swing arm 820 engages with the seventh concave-convex surface 789 of the second damping slider 780, the third swing arm 820 drives the second damping slider 780 to slide relative to the second main shaft 700 along the first direction X. The second damping slider 780 drives the second elastic element 770 to compress and deform. The elastic restoring force of the second elastic element 770 acts as a damping force, thus providing a damping effect when the third swing arm 820 rotates relative to the second main shaft 700.

[0313] Simultaneously, when the second rotating mechanism 40 switches between the unfolded and folded states, the fourth swing arm 920 rotates relative to the second main shaft 700. Since the sixth concave-convex surface 922 of the fourth swing arm 920 engages with the eighth concave-convex surface 788 of the second damping slider 780, the fourth swing arm 920 drives the second damping slider 780 to slide relative to the second main shaft 700 along the first direction X. The second damping slider 780 drives the second elastic element 770 to compress and deform. The elastic restoring force of the second elastic element 770 acts as a damping force, thus providing a damping effect when the fourth swing arm 920 rotates relative to the second main shaft 700.

[0314] In some embodiments, the second spindle 700 may further include a synchronization slider 790, which is slidably connected to the second spindle 700 along a first direction. The synchronization slider 790 may be located between two through holes at the first end 820a of the third swing arm and between two through holes at the first end 920a of the fourth swing arm.

[0315] The first end 820a of the third swing arm may include a first helical surface 823, the synchronous slider 790 may include a third helical surface 791 that cooperates with the first helical surface 823, the first end 920a of the fourth swing arm may include a second helical surface 923, and the synchronous slider 790 may include a fourth helical surface 792 that cooperates with the second helical surface 923.

[0316] With the above configuration, when the third swing arm 820 rotates relative to the second main shaft 700, the synchronous slider 790 slides relative to the second main shaft 700, thereby driving the fourth swing arm 920 to rotate relative to the second main shaft 700. Through the cooperation between the helical surfaces, the synchronous movement of the third swing arm 820 and the fourth swing arm 920 is achieved, which in turn achieves the synchronous movement of the third rotating shaft assembly 800 and the fourth rotating shaft assembly 900.

[0317] Of course, in some other embodiments, the third swing arm 820 and the fourth swing arm 920 can also achieve synchronous movement through other structures, and this application embodiment does not specifically limit this.

[0318] In some embodiments, the first end 820a of the third swing arm may further include a fifth gear, the first end 920a of the fourth swing arm may further include a sixth gear, the second main shaft 700 may further include a seventh gear meshing with the fifth gear, and the second main shaft 700 may further include an eighth gear meshing with the sixth gear. The seventh gear also meshes with the eighth gear.

[0319] Through the coordination of the four gears, the third swing arm 820 can rotate relative to the second main shaft 700 while the fourth swing arm 920 rotates relative to the second main shaft 700, thus achieving synchronous movement of the third swing arm 820 and the fourth swing arm 920.

[0320] In some embodiments, the second rotating mechanism may also be other structures. This application does not specifically limit the second rotating mechanism.

[0321] The following reference Figures 36 to 38 The structure of another second rotating mechanism will be further described. The difference between this second rotating mechanism and the one described in the above embodiment is that... Figure 36 The second rotating mechanism can omit the third fixed frame, fourth fixed frame, third swing arm, and fourth swing arm.

[0322] Figure 36 A partial enlarged view of M2 when the second rotating mechanism is in the deployed state, as provided in an embodiment of this application; Figure 37 for Figure 36 Exploded view of the second rotating mechanism in the diagram.

[0323] Reference Figure 36 and Figure 37As shown, the second rotating mechanism 40 may include a third rotating member 810, a second main shaft 700, and a fourth rotating member 910. The second main shaft 700 extends along the first direction X. The first end 810a of the third rotating member is rotatably connected to the second main shaft 700, and the second end 810b of the third rotating member is fixedly connected to the second structural member 22. The first end 910a of the fourth rotating member is rotatably connected to the second main shaft 700, and the second end 910b of the fourth rotating member is fixedly connected to the third structural member 23.

[0324] When the folding electronic device 1 is in the unfolded state, the third rotating member 810, the second main shaft 700 and the fourth rotating member 910 together constitute the support plane S of the second rotating mechanism 40.

[0325] When the foldable electronic device 1 is in a folded state, the support surface of the third rotating member 810 is parallel to the support surface of the fourth rotating member 910, and both the support surfaces of the third rotating member 810 and the fourth rotating member 910 are perpendicular to the third direction Z. For example, the flexible screen 30 can be bent into a U-shape within the second accommodating space P2 jointly enclosed by the third rotating member 810, the second main shaft 700, and the fourth rotating member 910.

[0326] In some embodiments, combined with Figure 38 As shown, the second rotating mechanism 40 also includes a synchronous gear 799, a first rack 7991 and a second rack 7992 disposed on the second main shaft 700. The first rack 7991 meshes with the synchronous gear 799 and is also connected to the first end 810a of the third rotating member. The second rack 7992 meshes with the synchronous gear 799 and is also connected to the first end 910a of the fourth rotating member.

[0327] For example, the first end 810a of the third rotating member may be provided with a protrusion that can be inserted into the groove of the first rack 7991; similarly, the first end 910a of the fourth rotating member may be provided with a protrusion that can be inserted into the groove of the second rack 7992.

[0328] With the above configuration, when the third rotating member 810 rotates relative to the second main shaft 700, the third rotating member 810 drives the first rack 7991 to move, and the first rack 7991 drives the synchronous gear 799 to rotate. As the synchronous gear 799 rotates, the second rack 7992 moves, and the direction of movement of the second rack 7992 is opposite to the direction of movement of the first rack 7991. The second rack 7992 drives the fourth rotating member 910 to rotate relative to the second main shaft 700, so that the third rotating member 810 and the fourth rotating member 910 can rotate synchronously.

[0329] In some embodiments, the second rotation mechanism may also include a second elastic element 770 and a second damping slider 780. The second elastic element 770 may be disposed on the second main shaft 700 along the first direction X, and the second damping slider 780 may be slidably connected to the second main shaft 700 along the first direction X.

[0330] The difference from the above embodiments is that the first end 810a of the third rotating member may include a fifth concave-convex surface 822, the second damping slider 780 may include a seventh concave-convex surface 789 that cooperates with the fifth concave-convex surface 822, the first end 910a of the fourth rotating member may include a sixth concave-convex surface 922, and the second damping slider 780 may include an eighth concave-convex surface 788 that cooperates with the sixth concave-convex surface 922.

[0331] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
