Description

Technical Field

[0001] This application relates to the field of foldable electronic products technology, and more particularly to a rotating mechanism and 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. In traditional inward-folding electronic devices, when the electronic device is folded, the flexible screen folds inside the housing. The bent portion of the flexible screen is easily damaged by excessive pressure from the housing, resulting in poor reliability of the flexible screen. Summary of the Invention

[0004] This application provides a rotating mechanism and a folding electronic device to improve the poor reliability of flexible screens.

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

[0006] On one hand, a rotating mechanism is provided, comprising: a main shaft, a first rotating shaft assembly, and a second rotating shaft assembly. The main shaft extends along a first direction.

[0007] The first rotating shaft assembly includes a first rotating component, a first connecting rod, a first fixed frame, and a first swing arm. The first end of the first rotating component is rotatably connected to the main shaft, and the second end of the first rotating component is slidably connected to the first fixed frame via a first sliding groove. The second end of the first rotating component can slide relative to the first fixed frame along the extending direction of the first sliding groove. The first end of the first connecting rod is rotatably connected to the first rotating component, and the second end of the first connecting rod is slidably connected to the first fixed frame via a first guide groove. The second end of the first connecting rod can slide relative to the first fixed frame along the extending direction of the first guide groove. The first end of the first swing arm is rotatably connected to the main shaft, and the second end of the first swing arm is slidably connected to the first fixed frame via a third sliding groove. The second end of the first swing arm can slide relative to the first fixed frame along the extending direction of the third sliding groove.

[0008] The second rotating shaft assembly includes a second rotating component, a second connecting rod, a second fixed frame, and a second swing arm. The first end of the second rotating component is rotatably connected to the 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 extending direction of the second sliding groove. The first end of the second connecting rod is rotatably connected to the second rotating component, and the second end of the second connecting rod is slidably connected to the second fixed frame via a second guide groove. The second end of the second connecting rod can slide relative to the second fixed frame along the extending direction of the second guide groove. The first end of the second swing arm is rotatably connected to the main shaft, and the second end of the second swing arm is slidably connected to the second fixed frame via a fourth sliding groove. The second end of the second swing arm can slide relative to the second fixed frame along the extending direction of the fourth sliding groove.

[0009] When the rotating mechanism is in the unfolded state, the first rotating shaft assembly and the second rotating shaft assembly are arranged along the second direction, and the first rotating shaft assembly, the main shaft, and the second rotating shaft assembly together form a support plane; the extension directions of the first slide groove and the second slide groove both intersect the support plane, the extension directions of the first guide groove and the second guide groove both intersect the support plane, and the orthographic projections of the extension directions of the first guide groove and the second guide groove onto the support plane are both perpendicular to the orthographic projection of the second direction onto the support plane.

[0010] A support plane can be used to support a flexible screen and improve its flatness when it is in a flat state. Here, "support plane" can be understood as a horizontal plane or a near-horizontal plane. The horizontal plane can be a horizontal surface parallel to the first direction and the second direction, and the near-horizontal plane can be a slightly undulating surface. The acceptable deviation range of the near-horizontal plane can be, for example, a deviation within 5%.

[0011] When the rotating mechanism is in the folded state, the first rotating shaft assembly, the main shaft, and the second rotating shaft assembly together form a receiving space. In the third direction, part of the first swing arm is located between the first connecting rod and the main shaft, and part of the second swing arm is located between the second connecting rod and the main shaft. The third direction is perpendicular to the support surface of the main shaft.

[0012] With the above configuration, when the electronic device is in a folded state and is subjected to an impact (or falls), the first swing arm can continue to slide relative to the first fixed frame along the extension direction of the third slide groove under the impact force. For example, the first swing arm can move towards... Figure 16B The first arm continues to slide upwards. When the first arm slides to contact the first link, the first link can act as a stop, that is, the first link can prevent the first arm from continuing to slide along the extension direction of the third slide groove, which helps to improve the phenomenon of shrinkage of the accommodating space.

[0013] Furthermore, since the first swing arm and the first connecting rod are in contact, the impact force can be shared by the first rotating component and the first swing arm. This helps to improve the problem of the first swing arm (or the first rotating component) collapsing or breaking due to the impact force being borne solely by the first swing arm (or the first rotating component), and helps to improve the structural reliability of the rotating mechanism.

[0014] Similarly, since the components in the second rotating shaft assembly operate on the same principle, when the electronic device is in a folded state and is subjected to an impact (or falls), the second linkage can also prevent the second swing arm from continuing to slide along the extension direction of the fourth slide groove, thereby mitigating the problem of reduced accommodating space. Furthermore, the impact force can be shared by the second rotating component and the second swing arm, which helps to address the issue of the second swing arm (or second rotating component) collapsing or breaking due to bearing the impact force alone, thus improving the structural reliability of the rotating mechanism.

[0015] In some embodiments, the rotation axis of the first connecting rod relative to the first rotating member is a first axis. The orthographic projection of the first axis onto the support plane intersects the orthographic projection of the extension direction of the first slide groove onto the support plane, and the orthographic projection of the first axis onto the support plane also intersects the orthographic projection of the first direction onto the support plane. The rotation axis of the second connecting rod relative to the second rotating member is a second axis. The orthographic projection of the second axis onto the support plane intersects the orthographic projection of the extension direction of the second slide groove onto the support plane, and the orthographic projection of the second axis onto the support plane also intersects the orthographic projection of the first direction onto the support plane.

[0016] By setting a first link, 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 through the first link. The positional relationship between the first rotating component and the first fixed frame is relatively stable, which helps to prevent the first rotating component from rotating relative to the first fixed frame. Similarly, by setting a second link, a strong constraint is formed between the second rotating component and the second fixed frame through the second link. The positional relationship between the second rotating component and the second fixed frame is relatively stable, which helps to prevent the second rotating component from rotating relative to the second fixed frame.

[0017] In summary, by setting the first link and the second link, when the foldable electronic device is impacted or dropped, it is beneficial to prevent the first or second pivot assembly from rotating relative to the main shaft, and to prevent the containment space enclosed by the first pivot assembly, the second pivot assembly, and the main shaft from squeezing the flexible screen, thus improving the reliability of the flexible screen.

[0018] In some embodiments, when the rotating mechanism is in the deployed state, the first swing arm and the first connecting rod are offset from each other in their orthographic projections onto the first reference plane, and the second swing arm and the second connecting rod are also offset from each other in their orthographic projections onto the first reference plane, which is perpendicular to the first direction. With this configuration, when the rotating mechanism is in the deployed state, the first connecting rod can avoid the movement trajectory of the first swing arm, and the movement of the first connecting rod relative to the first fixed frame does not interfere with the movement of the first swing arm relative to the first fixed frame; similarly, the second connecting rod can avoid the movement trajectory of the second swing arm, and the movement of the second connecting rod relative to the second fixed frame does not interfere with the movement of the second swing arm relative to the second fixed frame.

[0019] In some embodiments, when the rotating mechanism is in the deployed state, in the third direction, a portion of the first swing arm is located between the first link and the support plane, and a portion of the second swing arm is located between the second link and the support plane. This arrangement improves the assembly compactness between the first swing arm and the first link, and between the second swing arm and the second link, further reducing the size of the rotating mechanism.

[0020] In some embodiments, the first fixed frame includes a first hole, the second end of the first swing arm includes a first stop block, and the first fixed frame also includes a third slide groove communicating with the first hole; the second fixed frame includes a second hole, the second end of the second swing arm includes a second stop block, and the second fixed frame also includes a fourth slide groove communicating with the second hole. When the rotating mechanism is in the folded state, at least a portion of the first stop block is located at the communicating portion of the first hole and the third slide groove, and at least a portion of the second stop block is located at the communicating portion of the second hole and the fourth slide groove.

[0021] In this way, the first stop block 9 can be located on the movement trajectory of the first swing arm relative to the first fixed frame. When the folding electronic device is impacted (or falls), the first stop block 9 can block the movement of the first swing arm, and the first link can act as a stop, which helps to improve the phenomenon of reduced storage space. Similarly, the second stop block 9 can also be located on the movement trajectory of the second swing arm relative to the second fixed frame, and the second link can act as a stop.

[0022] In some embodiments, when the rotating mechanism is in the deployed state, at least a portion of the first stop block is located inside the first hole and outside the third slide groove, at least a portion of the second stop block is located inside the second hole and outside the fourth slide groove.

[0023] In this way, when the rotating mechanism is in the deployed state, the first link can avoid the movement trajectory of the first swing arm. The second link can avoid the movement trajectory of the second swing arm.

[0024] In some embodiments, when the rotating mechanism is in the deployed state: the distance between the first end of the first hole and the main shaft is equal to the distance between the second end of the first hole and the main shaft; the distance between the first end of the first hole and the supporting plane is less than the distance between the second end of the first hole and the supporting plane; and the first end of the first hole communicates with the third slide groove. The distance between the first end of the second hole and the main shaft is equal to the distance between the second end of the second hole and the main shaft; the distance between the first end of the second hole and the supporting plane is less than the distance between the second end of the second hole and the supporting plane; and the first end of the second hole communicates with the fourth slide groove.

[0025] With the above configuration, when the rotating mechanism is in the folded state, at least a portion of the first stop block 9 can be located at the first end 6a of the first hole, so that at least a portion of the first stop block 9 can be located at the connecting portion of the first hole 6 and the third slide groove. Similarly, when the rotating mechanism is in the folded state, at least a portion of the second stop block 9 can be located at the first end 6a of the second hole, so that at least a portion of the second stop block 9 can be located at the connecting portion of the second hole 6 and the fourth slide groove.

[0026] In some embodiments, the second end of the first link is slidably connected to the first fixed frame via a first guide groove, including: the second end of the first link and the first fixed frame are slidably connected via a first shaft and a first guide groove; the second end of the first link 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 link is connected to the first shaft. The second end of the second link is slidably connected to the second fixed frame via a second guide groove, including: the second end of the second link and the second fixed frame are slidably connected via a second shaft and a second guide groove; the second end of the second link 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 link is connected to the second shaft. Through the above arrangements, the first link and the first fixed frame are slidably connected, and the second link and the second fixed frame are slidably connected.

[0027] In some embodiments, in a first direction, the distance between the first end of the first guide groove and the first end of the first connecting rod is greater than the distance between the second end of the first guide groove and the first end of the first connecting rod. Similarly, 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. In the first direction, the distance between the first end of the second guide groove and the first end of the second connecting rod is greater than the distance between the second end of the second guide groove and the first end of the second connecting rod. In a 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. With these settings, the extension direction of the first guide groove can intersect the support plane, and the extension direction of the first guide groove can also intersect the first direction; the extension direction of the second guide groove can intersect the support plane, and the extension direction of the second guide groove can also intersect the first direction.

[0028] In some embodiments, where the second end of the first connecting rod includes a first guide groove, the first fixing frame is connected to the first shaft, and the second end of the second connecting rod includes a second guide groove, the second fixing frame is connected to the second shaft, in the case where: during the transition of the rotating mechanism from the unfolded state to the folded state, the first shaft 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 shaft 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. During the transition of the rotating mechanism from the folded state to the unfolded state, the first shaft moves relative to the first guide groove in a direction from the second end of the first guide groove to the first end of the first guide groove, and the second shaft moves relative to the second guide groove in a direction from the second end of the second guide groove to the first end of the second guide groove.

[0029] With the above configuration, during the transition of the rotating mechanism from the unfolded state to the folded state, the distance between the first end of the first link and the first shaft decreases, causing the first end of the first link to move 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; the distance between the first end of the second link and the second shaft decreases, causing the first end of the second link to move 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 rotating mechanism from the folded state to the unfolded state, the distance between the first end of the first link and the first shaft increases, causing the first end of the first link to move 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; the distance between the first end of the second link and the second shaft increases, causing the first end of the second link to move 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.

[0030] In some embodiments, the first end of the first link can slide relative to the first rotating member along the extension direction of the first axis, and the first end of the second link can slide relative to the second rotating member along the extension direction of the second axis.

[0031] With the above configuration, during the transition between the unfolded and folded states of the rotating mechanism, the first link and the first fixed frame can both slide relative to the first rotating component, and the second link and the second fixed frame can both slide relative to the second rotating component, thereby improving the smoothness of the rotating mechanism's movement.

[0032] In some embodiments, the first end of the first connecting rod includes a first connecting portion and a second connecting portion spaced apart; the first rotating member includes a first mating portion, a second mating portion, and a third mating portion spaced apart; the first end of the second connecting rod includes a third connecting portion and a fourth connecting portion spaced apart; and the second rotating member includes a fourth mating portion, a fifth mating portion, and a sixth mating portion spaced apart. When the rotating mechanism is in the deployed state, in the second direction, the third shaft passes through the first mating portion, the first connecting portion, the second mating portion, the second connecting portion, and the third mating portion in sequence, and the first end of the first swing arm and the first rotating member are rotatably connected via the third shaft. In the second direction, the fourth shaft passes through the fourth mating portion, the third connecting portion, the fifth mating portion, the fourth connecting portion, and the sixth mating portion in sequence, and the first end of the second swing arm and the second rotating member are rotatably connected via the fourth shaft.

[0033] In some embodiments, during the transition of the rotating mechanism from an unfolded state to a folded state, the first end of the first link moves relative to the first rotating member along a direction parallel to the first axis and from the main shaft toward the first fixed frame, and the first end of the second link moves relative to the second rotating member along a direction parallel to the second axis and from the main shaft toward the second fixed frame.

[0034] During the transition of the rotating mechanism from the folded state to the unfolded state, the first end of the first link moves relative to the first rotating member along a direction parallel to the first axis and from the first fixed frame toward the main shaft, and the first end of the second link moves relative to the second rotating member along a direction parallel to the second axis and from the second fixed frame toward the main shaft.

[0035] With the above configuration, when the rotating mechanism transitions from an unfolded state to a folded state, the first connecting rod slides away from the main shaft relative to the first rotating member, and the second connecting rod slides away from the main shaft relative to the second rotating member. Correspondingly, when the rotating mechanism transitions from a folded state to an unfolded state, the first connecting rod slides closer to the main shaft relative to the first rotating member, and the second connecting rod slides closer to the main shaft relative to the second rotating member.

[0036] In some embodiments, the first rotating member includes a first helical surface, and the first end of the first connecting rod includes a second helical surface that mates with the first helical surface, the first and second helical surfaces having the same direction of rotation. The second rotating member includes a third helical surface, and the first end of the second connecting rod includes a fourth helical surface that mates with the third helical surface, the third and fourth helical surfaces having the same direction of rotation, and the third helical surface having the opposite direction of rotation to the first helical surface.

[0037] Through the above configuration, the cooperation of the first and second helical surfaces prevents a large relative sliding space between the first end of the first connecting rod and the first rotating component; the cooperation of the third and fourth helical surfaces prevents a large relative sliding space between the first end of the second connecting rod and the second rotating component. This further prevents the first end of the first connecting rod from wobbling relative to the first rotating component, and the first end of the second connecting rod from wobbling relative to the second rotating component, when the rotating mechanism is subjected to an impact.

[0038] In some embodiments, the first end of the first link can slide relative to the first fixed frame along the extending direction of the first slide groove, and the first end of the first link can rotate relative to the main shaft. The first end of the second link can slide relative to the second fixed frame along the extending direction of the second slide groove, and the first end of the second link can rotate relative to the main shaft. With this configuration, during the transition between the unfolded and folded states of the rotating mechanism, the first end of the first link moves with the second end of the first rotating member, and the first end of the second link moves with the second end of the second rotating member.

[0039] In some embodiments, the first end of the first link and the first rotating member are rotatably connected via a third axis, and the first end of the second link and the second rotating member are rotatably connected via a fourth axis. When the rotating mechanism is in the unfolded state, in the thickness direction of the first rotating shaft assembly, the distance between the first axis and the supporting plane is greater than the distance between the third axis and the supporting plane; the distance between the first and third axes is a first distance. In the thickness direction of the second rotating shaft assembly, the distance between the second axis and the supporting plane is greater than the distance between the fourth axis and the supporting plane; the distance between the second and fourth axes is a second distance. During the transition of the rotating mechanism from the unfolded state to the folded state, in the thickness direction of the first rotating shaft assembly, the distance between the first and third axes is less than the first distance, and in the thickness direction of the second rotating shaft assembly, the distance between the second and fourth axes is less than the second distance. When the rotating mechanism is in the folded state, in the thickness direction of the first rotating shaft assembly, the distance between the first and third axes is less than the first distance, and in the thickness direction of the second rotating shaft assembly, the distance between the second and fourth axes is less than the second distance.

[0040] With the above settings, during the transition of the rotating mechanism from the unfolded state to the folded state, the space occupied by the first and third axes in the thickness direction of the first rotating shaft assembly is reduced, and the space occupied by the second and fourth axes in the thickness direction of the second rotating shaft assembly is reduced, which is conducive to achieving the thinning and lightening of foldable electronic devices.

[0041] 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 via a first slider and a first sliding groove, wherein the second end of the first rotating member includes the first slider and the first fixed frame includes the first sliding groove, or the first fixed frame includes the first slider and the second end of the first rotating member includes the first sliding groove. 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 via a second slider and a second sliding groove, wherein the second end of the second rotating member includes the second slider and the second fixed frame includes the second sliding groove, or the second fixed frame includes the second slider and the second end of the second rotating member includes the second sliding groove.

[0042] With the above configuration, the first fixed frame can slide relative to the first rotating member along the extension direction of the first slide groove, and the second fixed frame can slide relative to the second rotating member along the extension direction of the second slide groove.

[0043] In some embodiments, when the rotating mechanism is in the deployed state: in the second direction, the distance between the first end of the first slide groove and the main shaft is less than the distance between the second end of the first slide groove and the main shaft; and in the direction perpendicular to the support plane, the distance between the first end of the first slide groove and the support plane is greater than the distance between the second end of the first slide groove and the support plane. In the second direction, the distance between the first end of the second slide groove and the main shaft is less than the distance between the second end of the second slide groove and the main shaft; and in the direction perpendicular to the support plane, the distance between the first end of the second slide groove and the support plane is greater than the distance between the second end of the first slide groove and the support plane.

[0044] In some embodiments, during the transition of the rotating mechanism 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 rotating mechanism 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.

[0045] With the above configuration, when the rotating mechanism transitions from an unfolded state to a folded state, the first fixed frame slides away from the main axis relative to the first rotating member, and the second fixed frame slides away from the main axis relative to the second rotating member. Correspondingly, when the rotating mechanism transitions from a folded state to an unfolded state, the first fixed frame slides away from the main axis relative to the first rotating member, and the second fixed frame slides away from the main axis relative to the second rotating member. This facilitates adjustment of the length between the first and second fixed frames, ensuring that the length of the flexible screen remains unchanged during the unfolding or folding process of the rotating mechanism, and mitigating the squeezing or stretching phenomena on the flexible screen caused by the rotating mechanism.

[0046] In some embodiments, the first rotating shaft assembly further includes a first support plate and a second support plate. The first support plate is slidably connected to the first rotating member and rotatably connected to the first fixed frame. The second support plate is slidably connected to the second rotating member and rotatably connected to the second fixed frame. When the rotating mechanism is in the unfolded state, the first rotating shaft assembly, the main shaft, and the second rotating shaft assembly together form a support plane, including: the first support plate, the first fixed frame, the main shaft, the second support plate, and the second fixed frame together forming a support plane. When the rotating mechanism is in the folded state, the minimum distance between the support surfaces of the first support plate and the second support plate along the second direction is greater than or equal to the distance between the support surfaces of the first fixed frame and the second fixed frame along the second direction.

[0047] The above arrangement allows the first support plate to form part of the support surface of the first rotating shaft assembly and the second support plate to form part of the support surface of the second rotating shaft assembly when the rotating mechanism is in the unfolded state. It also allows the first rotating shaft assembly, the main shaft, and the second rotating shaft assembly to jointly enclose a teardrop-shaped or near-teardrop-shaped receiving space when the rotating mechanism is in the folded state.

[0048] In some embodiments, the first support plate and the first rotating member are slidably connected by 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. The second support plate and the second rotating member are slidably connected by 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.

[0049] With the above configuration, when the first mating shaft moves along the extension direction of the third guide groove, the first support plate and the first rotating member slide relative to each other. When the second mating shaft moves along the extension direction of the fourth guide groove, the second support plate and the second rotating member slide relative to each other.

[0050] On the other hand, a foldable electronic device is provided, including a flexible screen, a first structural member, a second structural member, and a rotating mechanism as described in any of the above embodiments; the first structural member and the second structural member are connected to both sides of the rotating mechanism, and the flexible screen is located on the same side of the first structural member and the second structural member and is connected to the first structural member and the second structural member; when the foldable electronic device is in an unfolded state, the supporting plane of the rotating mechanism is used to support the flexible screen; when the foldable electronic device is in a folded state, the first rotating shaft assembly, the main shaft, and the second rotating shaft assembly of the rotating mechanism together constitute an accommodating space, and part of the flexible screen is located within the accommodating space.

[0051] The folding electronic device provided in the embodiments of this application includes the rotation mechanism as described above, and therefore has all the above-described beneficial effects, which will not be repeated here.

[0052] In some embodiments, the first end of the first connecting rod and the first rotating member are rotatably connected via a third axis, and the second end of the first connecting rod and the first fixed frame are slidably connected via the first axis; the first end of the second connecting rod and the second rotating member are rotatably connected via a fourth axis, and the second end of the second connecting rod and the second fixed frame are slidably connected via a second axis. The extending directions of the first axis and the third axis are parallel to each other and both parallel to the support surface of the first structural member, which is used to connect with the flexible screen; the extending directions of the second axis and the fourth axis are parallel to each other and both parallel to the support surface of the second structural member, which is used to connect with the flexible screen.

[0086] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0087] In the following description, the terms "first," "second," etc., are used for ease of description only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0088] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0089] As used herein, terms such as “equal,” “parallel,” and “perpendicular” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equal items less than or equal to 5% of either one.

[0090] 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.

[0091] 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.

[0092] To facilitate understanding of the foldable electronic device 1 provided in the embodiments of this application. Figure 1 This is a structural diagram of a foldable electronic device in an unfolded state, provided in an embodiment of this application. The area enclosed by the dashed box in the diagram can be the placement area of ​​the flexible screen 30. Figure 2This is a structural diagram of a foldable electronic device in a folded state, provided as an embodiment of this application. The following is in conjunction with… Figure 1 and Figure 2 The following is a description of a foldable electronic device 1:

[0093] The foldable electronic device 1 may include a flexible screen 30. The flexible screen 30 may be an active matrix organic light emitting diode (AMOLED) display.

[0094] 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.

[0095] In addition, the foldable electronic device 1 also includes a rotating mechanism 10 for supporting the flexible screen 30, a first structural member 21, and a second structural member 22. The rotating mechanism 10 is connected between the first structural member 21 and the second structural member 22. The first structural member 21 and the second structural member 22 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 rotating mechanism 10. This application embodiment only briefly illustrates part of the structure of the first structural member 21 and the second structural member 22, and the accompanying drawings are also simplified. This application embodiment does not strictly limit the specific structure of the first structural member 21 and the second structural member 22.

[0096] The first structural member 21 and the second structural member 22 may each include a mid-frame structure for mounting and securing other components of the foldable electronic device 1. Examples include a camera, earphones, handset, buttons, and batteries. This embodiment does not limit the other electronic components mounted on the first structural member 21 and the second structural member 22. The first structural member 21 and the second structural member 22 may also each include a decorative cover plate for protecting the components inside the mid-frame structure and for presenting part of the appearance of the foldable electronic device 1.

[0097] For example, a portion of the flexible screen 30 can be fixed to the first structural member 21 by an adhesive layer, a portion can be fixed to the second structural member 22 by an adhesive layer, and a portion can be fixed to the rotating mechanism 10. The adhesive layer can be a thin film layer formed after applying adhesive. This application embodiment does not limit the specific form of the adhesive layer. For example, the adhesive layer can be an intermittent thin film layer, or the adhesive layer can be a whole thin film layer.

[0098] Figure 3 This is a structural diagram of a rotating mechanism in its deployed state, provided in an embodiment of this application. Figure 4 for Figure 3 A magnified view of point M, where the rotating mechanism is in a folded state. (Refer to...) Figure 3 and Figure 4 The rotating mechanism 10 includes a main shaft 100, a first rotating shaft assembly 200, and a second rotating shaft assembly 300.

[0099] For ease of explanation, the extension direction of the main shaft 100 is defined as the first direction X, and the arrangement direction of the first pivot assembly 200 and the second pivot assembly 300 when the foldable electronic device 1 is in the unfolded state is defined as the second direction Y. That is, the second direction Y can be the direction in which the first pivot assembly 200 points to the second pivot assembly 300 when the foldable electronic device 1 is in the unfolded state. The second direction Y is perpendicular to the first direction X. The thickness direction of the main shaft 100 is defined as the third direction Z. That is, the third direction Z can be perpendicular to the support surface of the main shaft 100. The third direction Z is also perpendicular to the plane containing the first direction X and the second direction Y.

[0100] For example, the first rotating shaft assembly 200 is rotatably connected to the main shaft 100, and is also connected to the first structural member 21; the second rotating shaft assembly 300 is rotatably connected to the main shaft 100, and is also connected to the second structural member 22. The rotation axis of the first rotating shaft assembly 200 relative to the main shaft 100 and the rotation axis of the second rotating shaft assembly 300 relative to the main shaft 100 are both parallel to the first direction X. With the above configuration, the first structural member 21 can drive the first rotating shaft assembly 200 to rotate relative to the main shaft 100, and the second structural member 22 can drive the second rotating shaft assembly 300 to rotate relative to the main shaft 100, thereby realizing the folding or unfolding of the foldable electronic device.

[0101] like Figure 3 As shown, when the foldable electronic device is in the unfolded state, the included angle between the first structural member 21 and the second structural member 22 can be approximately 180° (understandably, a slight deviation in the included angle between the first structural member 21 and the second structural member 22 is also allowed, for example, the included angle can be 165°, 177°, or 185°). At this time, the rotating mechanism is also in the unfolded state, and the first rotating shaft assembly 200 and the second rotating shaft assembly 300 are arranged along the second direction Y. The first rotating shaft assembly 200, the main shaft 100, and the second rotating shaft assembly 300 together constitute the support plane S. The support plane S can be used to support the flexible screen and improve the flatness of the flexible screen in the unfolded state.

[0102] Here, "support plane S" can be understood as a plane or an approximate plane. The plane can be a surface parallel to the first direction X and the second direction Y. The approximate plane can be a slightly undulating surface, and the acceptable deviation range of the approximate plane can be, for example, a deviation within 5%.

[0103] In some embodiments, the flexible screen 30 can be fixed to the first rotating shaft assembly 200 and the second rotating shaft assembly 300 by adhesive layers. The thickness of the adhesive layer can be adjusted to adjust the support effect of the rotating mechanism 10 on the flexible screen, thereby ensuring that the flexible screen is in the unfolded state. In this case, "together forming the support plane S" can also be understood as adjusting the thickness of the adhesive layers between the flexible screen and the first rotating shaft assembly 200, and between the flexible screen and the second rotating shaft assembly 300, so that the first rotating shaft assembly 200, the main shaft 100, and the second rotating shaft assembly 300 together form the support plane S, thereby ensuring that the flexible screen is in the unfolded state when unfolded.

[0104] Furthermore, when the foldable electronic device is in the unfolded state, the support surfaces of the first structural component and the second structural component can also be used to support the flexible screen, and the support surfaces of the first structural component and the second structural component can also be connected to the flexible screen.

[0105] like Figure 4 As shown, when the foldable electronic device is in a folded state, the included angle between the first structural member 21 and the second structural member 22 can be approximately 0° (it is understood that the included angle between the first structural member 21 and the second structural member 22 is also allowed to have a slight deviation, for example, the included angle can be 1°, 3° or 5°). At this time, the flexible screen is in a folded state, and the first pivot assembly 200 and the second pivot assembly 300 are also in a folded state, that is, the rotating mechanism is in a folded state.

[0106] In some embodiments, when the foldable electronic device is in a folded state, the first structural member 21 and the second structural member 22 can contact each other to achieve positioning. Alternatively, the first structural member 21 and the second structural member 22 can also be close to each other with a small gap between them; this embodiment does not specifically limit this.

[0107] In some embodiments, when the rotating mechanism 10 is in a folded state, the first rotating shaft assembly 200, the second rotating shaft assembly 300, and the main shaft 100 can jointly enclose a receiving space P, within which a portion of the flexible screen can be located. When the foldable electronic device is impacted or dropped, the first rotating shaft assembly 200 or the second rotating shaft assembly 300 may oscillate relative to the main shaft 100, causing the enclosed receiving space to decrease. This, in turn, causes the flexible screen located within the receiving space to be compressed, affecting the reliability of the flexible screen.

[0108] Figure 5 for Figure 3 Exploded view of the partial structure at point M of the rotating mechanism; Figure 6 for Figure 3 An exploded view of the rotating mechanism at point M. See below for reference. Figure 5 and Figure 6 The rotating mechanism provided in the embodiments of this application is described as follows:

[0109] 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 connecting rod 220, and the second rotating shaft assembly 300 includes a second rotating member 310, a second fixed frame 330 and a second connecting rod 320.

[0110] For example, in the first rotating shaft assembly 200, the number of the first rotating member 210, the first fixed bracket 230, and the first connecting rod 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 connecting 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 kinematic 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.

[0111] Similarly, in the second rotating shaft assembly 300, the number of the second rotating member 310, the second fixed frame 330, and the second connecting rod 320 is not limited. The structure of the multiple components in the second rotating shaft assembly 300 is also not limited; as long as the multiple components have the same kinematic principle, it will not be elaborated further here.

[0112] The first end 210a of the first rotating component is rotatably connected to the 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 connecting rod is rotatably connected to the first rotating component 210, and the second end 220b of the first connecting rod is slidably connected to the first fixed frame 230.

[0113] The first end 210a of the first rotating member can be parallel to the first direction X relative to the rotation axis of the main shaft 100, and the second end 210b of the first rotating member can slide relative to the first fixed frame 230 through the first sliding groove 231. The rotation axis of the first connecting rod 220 relative to the first rotating member 210 is the first axis L1, and the second end 220b of the first connecting rod can slide relative to the first fixed frame 230 through the first guide groove 224.

[0114] Similarly, the first end 310a of the second rotating member is rotatably connected to the 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 connecting rod is rotatably connected to the second rotating member 310, and the second end 320b of the second connecting rod is slidably connected to the second fixed frame 330.

[0115] The first end 310a of the second rotating member can be parallel to the first direction X relative to the rotation axis of the main shaft 100, and the second end 310b of the second rotating member can slide relative to the second fixed frame 330 through the second sliding groove 331. The rotation axis of the second connecting rod 320 relative to the second rotating member 310 is the second axis L2, and the second end 320b of the second connecting rod can slide relative to the second fixed frame 330 through the second guide groove 324.

[0116] Furthermore, the first fixing frame 230 can also be connected to the first structural member 21, so that the rotating mechanism is connected to the first structural member 21 through the first fixing frame 230. The second fixing frame 330 can also be connected to the second structural member 22, so that the rotating mechanism is connected to the second structural member 22 through the second fixing frame 330.

[0117] Figure 7 This is an assembly structure diagram of a spindle 100, a first rotating component 210, a second rotating component 310, a first fixed frame 230, and a second fixed frame 330 provided for embodiments of this application.

[0118] Reference Figure 7 As shown, the first end 210a of the first rotating member and the main shaft 100 can be rotatably connected via a first arc-shaped slider 211 and a first arc-shaped groove 101. The first end 210a of the first rotating member may include the first arc-shaped slider 211, and the main shaft 100 may include the first arc-shaped groove 101. The first end 310a of the second rotating member and the main shaft 100 can be rotatably connected via a second arc-shaped slider 311 and a second arc-shaped groove 102. The first end 310a of the second rotating member may include the second arc-shaped slider 311, and the main shaft 100 includes the second arc-shaped groove 102.

[0119] Figure 8 An exploded view of a spindle structure provided in an embodiment of this application. (Refer to...) Figure 8 The main shaft 100 may include an inner main shaft and an outer main shaft 110 stacked along a third direction Z, wherein the inner main shaft is closer to the flexible screen than the outer main shaft 110. The inner main shaft may include a first shaft portion 121 and a second shaft portion 122. The first shaft portion 121 and the second shaft portion 122 together form a first arc-shaped groove 101 and a second arc-shaped groove 102. The first arc-shaped groove 101 and the second arc-shaped groove 102 may be spaced apart along a second direction Y, and the central axis of the first arc-shaped groove 101 and the central axis of the second arc-shaped groove 102 are both parallel to the first direction X.

[0120] Accordingly, 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 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 main shaft 100 can be rotatably connected through a virtual axis connection. With the above arrangement, the rotation axis of the first rotating member 210 relative to the main shaft 100 and the rotation axis of the second rotating member 310 relative to the main shaft 100 are both parallel to the first direction X and do not coincide.

[0121] Figure 9A for Figure 5 A cross-sectional view along section line AA of the rotating mechanism in its unfolded state; Figure 9B for Figure 5 A cross-sectional view along section line AA showing the rotating mechanism in a folded state.

[0122] Reference Figure 9A and Figure 9B As shown, during the transition 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, during the transition 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.

[0123] In addition, in some other embodiments, the first rotating member 210 may also include a first arc-shaped slide groove 101, and the main shaft 100 may include a first arc-shaped slider 211, so that the first rotating member 210 and the main shaft 100 can be rotatably connected through the first arc-shaped slide groove 101 and the first arc-shaped slider 211; the second rotating member 310 may also include a second arc-shaped slide groove 102, and the main shaft 100 may include a second arc-shaped slider 311, so that the second rotating member 310 and the main shaft 100 can be rotatably connected through the second arc-shaped slide groove 102 and the second arc-shaped slider 311.

[0124] Of course, the first rotating member 210 and the main shaft 100 can also be rotatably connected through other virtual axis connection methods, and the second rotating member 310 and the main shaft 100 can also be rotatably connected through other virtual axis connection methods. This application embodiment does not limit this.

[0125] In this embodiment of the application, when the rotating mechanism is in the unfolded state, the extending direction of the first slide groove 231 (for example, it can be referred to...) Figure 9A and Figure 9B The F1 direction of the first groove 231 can intersect the support plane S, and the extension direction of the first groove 231 also intersects the direction perpendicular to the support plane S. For example, the extension direction of the first groove 231 can have an angle with the support plane S, and the angle is greater than 0 and less than 90 degrees.

[0126] Similarly, when the rotating mechanism is in the deployed state, the extension direction of the second slide 331 (for example, it can be referred to...) Figure 9A and Figure 9B The F3 direction of the second slide groove 331 can intersect the support plane S, and the extension direction of the second slide groove 331 also intersects the direction perpendicular to the support plane S. For example, the extension direction of the second slide groove 331 can have an angle with the support plane S, and the angle is greater than 0 and less than 90 degrees.

[0127] With the above configuration, during the transition of the rotating mechanism from the unfolded state to the folded state, the first fixed frame 230 slides away from the main shaft 100 via the first rotating member 210, and the second fixed frame 330 slides away from the main shaft 100 relative to the second rotating member 310. This facilitates adjustment of the length between the first fixed frame 230 and the second fixed frame 330, ensuring that the length of the flexible screen remains unchanged during the unfolding or folding process of the rotating mechanism, and mitigating the squeezing or stretching phenomenon of the flexible screen by the rotating mechanism.

[0128] Figure 10 This is a partial structural diagram of a first fixing frame and a second fixing frame provided in an embodiment of this application, viewed from one angle.

[0129] In some embodiments, continue to refer to Figure 7 and combined Figure 10 As shown, the second end 210b of the first rotating member and the first fixed frame 230 are slidably connected by a first slider 212 and a first sliding groove 231. The second end 210b of the first rotating member includes the first slider 212, and the first fixed frame 230 includes the first sliding groove 231. The second end 310b of the second rotating member and the second fixed frame 330 are slidably connected by a second slider 312 and a second sliding groove 331. The second end 310b of the second rotating member includes the second slider 312, and the second fixed frame 330 includes the second sliding groove 331.

[0130] 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 of the second slide groove 331.

[0131] Reference Figure 9AWhen 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 main shaft 100 is less than the distance between the second end 231b of the first slide groove and the 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.

[0132] Similarly, in the second direction Y, when the rotating mechanism is in the unfolded state, the distance between the first end 331a of the second slide and the main shaft 100 is less than the distance between the second end 331b of the second slide and the 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.

[0133] Combination Figure 9A and Figure 9B 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.

[0134] 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.

[0135] With the above configuration, during the transition from the unfolded state to the folded state of the rotating mechanism, the first fixed frame 230 slides away from the main shaft 100 relative to the first rotating member 210, and the second fixed frame 330 slides away from the main shaft 100 relative to the second rotating member 310. Correspondingly, during the transition from the folded state to the unfolded state of the rotating mechanism, the first fixed frame 230 slides closer to the main shaft 100 relative to the first rotating member 210, and the second fixed frame 330 slides closer to the main shaft 100 relative to the second rotating member 310. This facilitates adjustment of the length between the first fixed frame 230 and the second fixed frame 330, ensuring that the length of the flexible screen remains unchanged during the unfolding or folding process of the rotating mechanism, and mitigating the squeezing or stretching phenomena on the flexible screen caused by the rotating mechanism.

[0136] Furthermore, based on the same inventive concept, in some other embodiments, the first slide groove can also be disposed on the first rotating member 210, and the first slider 212 can be disposed on the first fixed frame 230, so that the first rotating member 210 and the first fixed frame 230 can be rotatably connected through the first slide groove 231 and the first slider 212; the second rotating member 310 can also include the second slide groove 331, and the second fixed frame 330 can include the second slider 312, so that the second rotating member 310 and the second fixed frame 330 can be rotatably connected through the second slide groove 331 and the second slider 312.

[0137] Of course, the first rotating member 210 and the first fixed frame 230 can also be slidably connected by other connection methods, and the second rotating member 310 and the second fixed frame 330 can also be slidably connected by other connection methods. The specific structure and structural relationship of the first sliding groove 231, the first slider 212, the second sliding groove 331, and the second slider 312 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.

[0138] Figure 11 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 12A An exploded view of a partial structure of a first rotating assembly and a second rotating assembly provided in an embodiment of this application; Figure 12B This is a structural diagram of a first link and a second link provided in an embodiment of this application.

[0139] In some embodiments, refer to Figure 11 , Figure 12A and Figure 12B The second end 220b of the first connecting rod is slidably connected to the first fixed frame 230, and may include: the second end 220b of the first connecting rod and the first fixed frame 230 may be slidably connected through the first shaft 410 and the first guide groove 224. The second end 220b of the first connecting rod may include the first guide groove 224, and the first fixed frame 230 may be connected to the first shaft 410.

[0140] In this embodiment of the application, when the rotating mechanism is in the unfolded state, the extension direction of the first guide groove 224 (for example, it can be...) Figure 12A and Figure 12B The F2 direction (in the diagram) can intersect with the supporting plane S. However, in this embodiment, the angle between the extension direction of the first guide groove 224 and the supporting plane S is not specifically limited.

[0141] Furthermore, when the rotating mechanism is in the deployed state, the projection of the extension direction of the first guide groove 224 onto the support plane S can also be perpendicular to the projection of the second direction Y onto the support plane S. For example, the extension direction of the first fixed frame 230 (i.e., the first direction X) can also be perpendicular to the second direction Y. When the second end 220b of the first connecting rod slides relative to the first fixed frame 230, the second end 220b of the first connecting rod can have a certain component of movement relative to the first fixed frame 230 in the extension direction of the first fixed frame 230 (i.e., the length direction of the first fixed frame 230).

[0142] Similarly, refer to Figure 11 , Figure 12A as well as Figure 12B The second end 320b of the second connecting rod is slidably connected to the second fixed frame 330, and may include: the second end 320b of the second connecting rod and the second fixed frame 330 can be slidably connected through the second shaft 510 and the second guide groove 324. Specifically, the second end 320b of the second connecting rod includes the second guide groove 324, and the second fixed frame 330 is connected to the second shaft 510.

[0143] In this embodiment of the application, when the rotating mechanism is in the unfolded state, the extension direction of the second guide groove 324 (for example, it can be...) Figure 12A and Figure 12B The F4 direction in the guide groove 324 can intersect with the support plane S. However, this embodiment does not specifically limit the angle between the extension direction of the second guide groove 324 and the support plane S.

[0144] Furthermore, when the rotating mechanism is in the deployed state, the projection of the extension direction of the second guide groove 324 onto the support plane S can also be perpendicular to the projection of the second direction Y onto the support plane S. For example, the extension direction of the second fixed frame 330 (i.e., the first direction X) can also be perpendicular to the second direction Y. When the second end 320b of the second link slides relative to the second fixed frame 330, the second end 320b of the second link can have a certain component of movement relative to the second fixed frame 330 in the extension direction of the second fixed frame 330 (i.e., the length direction of the second fixed frame 330).

[0145] Furthermore, based on the same inventive concept, in some other embodiments, the first shaft 410 can be disposed at the second end 220b of the first connecting rod, and the first guide groove 224 can be disposed at the first fixing frame 230, so that the second end 220b of the first connecting rod and the first fixing frame 230 can be slidably connected through the first shaft 410 and the first guide groove 224; the second shaft 510 can be disposed at the second end 320b of the second connecting rod, and the second guide groove 324 can be disposed at the second fixing frame 330, so that the second end 320b of the second connecting rod and the second fixing frame 330 can be slidably connected through the second shaft 510 and the second guide groove 324.

[0146] Of course, the first connecting rod 220 and the first fixed frame 230 can also be slidably connected by other connection methods, and the second connecting rod 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.

[0147] In some embodiments, the first end 220a of the first connecting rod and the first rotating member 210 can be rotatably connected via a third shaft 420. The first end 320a of the second connecting rod and the second rotating member 310 can be rotatably connected via a fourth shaft 520.

[0148] The direction of extension of the central axis of the third axis 420 is the same as that of the first axis L1. Figure 13A for Figure 11 A cross-sectional view along section line N1-N1 of the rotating mechanism in the unfolded state; Figure 13B for Figure 11 A cross-sectional view along section line N1-N1 showing the rotating mechanism in its folded state. (Combined with...) Figure 13A and Figure 13B As shown, the orthographic projection of the first axis L1 onto the supporting plane S coincides with the extension direction of the first groove 231 (e.g., Figure 13A and Figure 13B The projection of the first axis L1 onto the support plane S intersects with the projection of the first direction X onto the support plane S. The projection of the first axis L1 onto the support plane S also intersects with the projection of the first direction X onto the support plane S.

[0149] This application does not specifically limit the angle between the orthographic projection of the first axis L1 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 L1 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 L1 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 L1 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.

[0150] In this embodiment of the application, since the first end 220a of the first link can rotate relative to the first rotating member 210 with the second end 210b of the first rotating member, and the first rotating member 210 can also slide relative to the first fixed frame 230 with the second end 210b of the first rotating member, the position of the first axis L1 relative to the first fixed frame 230 changes during the process of the rotating mechanism changing from the unfolded state to the folded state.

[0151] Similarly, the extension direction of the central axis of the fourth axis 520 is the same as that of the second axis L2. Figure 14A for Figure 11 A cross-sectional view along section line N2-N2 of the rotating mechanism in the unfolded state; Figure 14B for Figure 11 A cross-sectional view along section line N2-N2 showing the rotating mechanism in its folded state. (Combined with...) Figure 14A and Figure 14B As shown, the orthographic projection of the second axis L2 onto the supporting plane S coincides with the extension direction of the second groove 331 (e.g., Figure 14A and Figure 14B The projection of the first direction X onto the support plane S intersects the projection of the second axis L2 onto the support plane S. The projection of the second axis L2 onto the support plane S also intersects the projection of the first direction X onto the support plane S.

[0152] This application does not specifically limit the angle between the orthographic projection of the second axis L2 onto the support plane S and the orthographic projection of the extension direction of the second slide groove 331 onto the support plane S, nor the angle between the orthographic projection of the second axis L2 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 L2 onto the support plane S and the orthographic projection of the extension direction of the second slide groove 331 onto the support plane S can be acute, right, or obtuse, and the angle between the orthographic projection of the second axis L2 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.

[0153] In this embodiment, since the first end 320a of the second link can rotate relative to the second rotating member 310 with the second end 310b of the second rotating member, and the second rotating member 310 also slides relative to the second fixed frame 330, the second axis L2 can change with the position of the second end 310b of the second rotating member relative to the second fixed frame 330 during the transition of the rotating mechanism from the unfolded state to the folded state.

[0154] By setting the first link 220, when the electronic device is in the unfolded or folded state, a strong constraint is formed between the first rotating member 210 and the first fixed frame 230 through the first link 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 setting the second link 320, when the electronic device is in the unfolded or folded state, it helps to prevent the second rotating member 310 from rotating relative to the second fixed frame 330.

[0155] In summary, by setting the first link 220 and the second link 320, when the electronic device is in an unfolded or folded state, and the folded electronic device is subjected to an impact or falls, it helps to prevent the first pivot assembly 200 or the second pivot assembly 300 from rotating relative to the main shaft 100. This prevents the containment space enclosed by the first pivot assembly 200, the second pivot assembly 300, and the main shaft 100 from squeezing the flexible screen, thus improving the reliability of the flexible screen.

[0156] Figure 15 An exploded view of the assembly structure between a first fixed frame and a first swing arm, a second fixed frame and a second swing arm, provided in an embodiment of this application.

[0157] In some embodiments, refer to Figure 6 and Figure 15 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 main shaft 100, the second end 250b of which may be slidably connected to the first fixed frame 230, and the first swing arm 250 may slide relative to the first fixed frame 230 along the extension direction of the third slide groove 235.

[0158] For example, the first fixing frame 230 may include a third slide groove 235, the extension direction of which may be perpendicular to the extension direction of the first fixing frame 230. The extension direction of the third slide groove 235 and the extension direction of the first slide groove 231 intersect in the orthographic projection of the third direction Z and the second direction Y in the plane.

[0159] The second end 250b of the first swing arm may include a third slider 251, which is slidably connected to the third slide 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.

[0160] Similarly, the second rotating shaft assembly 300 also includes a second swing arm 350, the first end 350a of which is rotatably connected to the main shaft 100, the rotation axis of the second swing arm 350 relative to the main shaft 100 is parallel to the first direction X, and the second end 350b of the second swing arm can slide relative to the second fixed frame 330 along the extension direction of the fourth slide groove 335.

[0161] For example, the second fixing frame 330 may include a fourth slide groove 335, the extension direction of which may be perpendicular to the extension direction of the second fixing frame 330. The extension direction of the fourth slide groove 335 intersects the orthographic projection of the extension direction of the second slide groove 331 into the plane containing the third direction Z and the second direction Y.

[0162] The second end 350b of the second swing arm may include a fourth slider 351, which is slidably connected to a fourth slide groove 335. With the above configuration, 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.

[0163] Figure 16A for Figure 5 A cross-sectional view along section line BB of the rotating mechanism in its unfolded state; Figure 16B for Figure 5 A cross-sectional view along section line BB of the rotating mechanism in a folded state.

[0164] Reference Figure 16A and Figure 16B As shown, during the transition from the unfolded state to the folded state of the rotating mechanism, the first fixed frame 230 slides away from the main shaft 100 relative to the second end 250b of the first swing arm, and the second fixed frame 330 slides away from the main shaft 100 relative to the second end 350b of the second swing arm. This arrangement facilitates adjustment of the length between the first fixed frame 230 and the second fixed frame 330, helps ensure that the length of the flexible screen remains unchanged, and mitigates the squeezing or stretching phenomenon of the rotating mechanism on the flexible screen.

[0165] In addition, continue to refer to Figure 16BWhen the rotating mechanism is in the folded state, in the third direction Z, part of the first swing arm 250 can be located between the first link 220 and the main shaft 100, and part of the second swing arm 350 can be located between the second link 320 and the main shaft 100.

[0166] Figure 17 This application provides structural diagrams of a rotating mechanism in a folded state from different viewpoints, according to embodiments of the present application. Figure 17 The attached diagram at the top is a structural diagram of the folded state from a first perspective. The first perspective can be a side view, for example, a view parallel to the second direction. Figure 17 The attached diagram below shows the structure in its folded state from a second perspective. The second perspective can be a top-down view, or for example, a view parallel to the third direction Z.

[0167] In order to facilitate observation of the positional relationship between the first connecting rod 220 and the first fixed frame, the second connecting rod 320 and the second fixed frame, Figure 17 Some components are omitted from the drawing; for example, the first and second fixing brackets are omitted. Furthermore, when... Figure 17 When the first viewpoint in the upper attached diagram is the viewpoint in the first direction, the observed rotating axis assembly can be the second rotating axis assembly. Figure 17 When the first viewpoint in the upper part of the attached diagram is the viewpoint opposite to the first direction, the observed rotating shaft assembly can be the first rotating shaft assembly.

[0168] For example, refer to Figure 17 The second end 220b of the first link may include a first stop block 229. When the rotating mechanism is in the folded state, in the third direction Z, the third slider 251 of the first swing arm 250 may be located between the first stop block 229 and the main shaft 100. For example, in the third direction Z, at least a portion of the orthographic projection of the third slider 251 on the main shaft 100 overlaps with the orthographic projection of the first stop block 229 on the main shaft 100.

[0169] Similarly, the second end 320b of the second link may include a second stop block 329. When the rotating mechanism is in the folded state, in the third direction Z, the fourth slider 351 of the second swing arm 350 may be located between the second stop block 329 and the main shaft 100. For example, in the third direction Z, the orthographic projection of the fourth slider 351 of the second swing arm 350 on the main shaft 100 overlaps with a portion of the orthographic projection of the second stop block 329 on the main shaft 100.

[0170] The following section uses a component from the first pivot assembly as an example to explain the motion principle of a foldable electronic device when it is impacted (or dropped).

[0171] Combination Figure 16B As can be seen, with the above configuration, when the electronic device is in a folded state and is subjected to an impact (or falls), under the action of the impact force, the first swing arm 250 can continue to slide relative to the first fixed frame along the extending direction of the third slide groove 235. For example, the first swing arm 250 can slide towards... Figure 16B The first swing arm 250 continues to slide upwards. When the first swing arm 250 slides to contact the first link 220, the first link 220 can act as a stop, that is, the first link 220 can prevent the first swing arm 250 from continuing to slide along the extension direction of the third slide groove 235, which helps to improve the phenomenon of shrinkage of the accommodating space.

[0172] Furthermore, since the first swing arm 250 and the first connecting rod 220 are in contact, the impact force can be shared by the first rotating member and the first swing arm 250. This helps to improve the problem of the first swing arm 250 (or the first rotating member) collapsing or breaking due to the impact force being borne solely by the first swing arm 250 (or the first rotating member), and helps to improve the structural reliability of the rotating mechanism.

[0173] Similarly, since the components in the second rotating shaft assembly operate on the same principle, when the electronic device is in a folded state and is subjected to an impact (or falls), the second link 320 can also prevent the second swing arm 350 from continuing to slide along the extension direction of the fourth slide groove 335, thereby improving the phenomenon of reduced accommodating space. Furthermore, the impact force can be shared by the second rotating member and the second swing arm 350, which helps to improve the problem of the second swing arm 350 (or the second rotating member) collapsing or breaking due to the impact force being borne solely by the second swing arm 350 (or the second rotating member), thus improving the structural reliability of the rotating mechanism.

[0174] In the embodiments of this application, reference is made to Figure 13A and Figure 14A As shown, when the rotating mechanism is in the unfolded state, the orthographic projections of the extension direction of the third slide groove 235 and the extension direction of the first guide groove 224 on the support plane intersect, and the orthographic projections of the extension direction of the fourth slide groove 335 and the extension direction of the second guide groove 324 on the support plane intersect.

[0175] In this way, during the transition between the unfolded and folded states of the rotating mechanism, the relative positional relationship between the second end 220b of the first link and the first swing arm 250 changes, and the relative positional relationship between the second end 320b of the second link and the second swing arm 350 changes. That is, the relative positional relationship between the first stop block 229 and the first swing arm 250 changes, and the relative positional relationship between the second stop block 329 and the second swing arm 350 changes.

[0176] Figure 18This application provides structural diagrams of a rotating mechanism in its deployed state from different viewpoints, according to embodiments of the present application. Figure 18 The attached diagram at the top is a structural diagram of the unfolded state from a first perspective. The first perspective can be a side view, for example, a view parallel to the second direction. Figure 18 The attached diagram below shows the structure in its unfolded state from a second perspective. The second perspective can be a top-down view, or for example, a view parallel to the third direction Z.

[0177] In order to facilitate observation of the positional relationship between the first connecting rod 220 and the first fixed frame, the second connecting rod 320 and the second fixed frame, Figure 18 Some components are omitted from the drawing; for example, the first and second fixing brackets are omitted. Furthermore, when... Figure 18 When the first viewpoint in the upper attached diagram is the viewpoint in the first direction, the observed rotating axis assembly can be the second rotating axis assembly. Figure 18 When the first viewpoint in the upper part of the attached diagram is the viewpoint opposite to the first direction, the observed rotating shaft assembly can be the first rotating shaft assembly.

[0178] The following is combined Figure 18 The relative positional relationship between the second end 220b of the first connecting rod and the first swing arm 250, and the relative positional relationship between the second end 320b of the second connecting rod and the second swing arm 350, are described when the rotating mechanism is in the deployed state.

[0179] For example, when the rotating mechanism is in the extended state, the projections of the first swing arm 250 and the first connecting rod 220 onto the first reference plane can be staggered, and the projections of the second swing arm 350 and the second connecting rod 320 onto the first reference plane can also be staggered. The first reference plane can be perpendicular to a first direction. For example, the first reference plane can be parallel to a second direction and a third direction Z.

[0180] For example, when the rotating mechanism is in the extended state, the orthographic projections of the first swing arm 250 and the first connecting rod 220 on the first reference plane do not overlap, and the orthographic projections of the second swing arm 350 and the second connecting rod 320 on the first reference plane do not overlap.

[0181] With the above configuration, when the rotating mechanism is in the extended state, the first link 220 can avoid the movement trajectory of the first swing arm 250, and the movement of the first link 220 relative to the first fixed frame does not interfere with the movement of the first swing arm 250 relative to the first fixed frame; the second link 320 can avoid the movement trajectory of the second swing arm 350, and the movement of the second link 320 relative to the second fixed frame does not interfere with the movement of the second swing arm 350 relative to the second fixed frame.

[0182] In some embodiments, when the rotating mechanism is in the deployed state, in the third direction Z, a portion of the first swing arm 250 is located between the first link 220 and the support plane S, and a portion of the second swing arm 350 is located between the second link 320 and the support plane S.

[0183] For example, when the rotating mechanism is in the deployed state, at least a portion of the first swing arm 250 and the first connecting rod 220 overlap in the third direction Z, and at least a portion of the second swing arm 350 and the second connecting rod 320 overlap. This arrangement improves the assembly compactness between the first swing arm 250 and the first connecting rod 220, and between the second swing arm 350 and the second connecting rod 320, further reducing the size of the rotating mechanism.

[0184] In some embodiments, during the transition between the folded and unfolded states of the rotating mechanism, the movement trajectories of the first stop block 229 relative to the first fixed frame and the first swing arm 250 relative to the first fixed frame intersect. Similarly, during the transition between the folded and unfolded states of the rotating mechanism, the movement trajectories of the second stop block 329 relative to the second fixed frame and the second swing arm 350 relative to the second fixed frame intersect.

[0185] Figure 19 for Figure 5 A sectional view of the first and second fixing brackets along the BB section line.

[0186] For example, refer to Figure 19 As shown, the first fixing bracket 230 may further include a first hole 236, which is connected to the third sliding groove 235. The second fixing bracket 330 may further include a second hole 336, which is connected to the fourth sliding groove 335.

[0187] Combination Figure 16A and Figure 16B As shown, the first stop block 229 can move within the first hole 236 so that it can move to a position within the third slide groove 235, or it can move to a position outside the third slide groove 235. The second stop block 329 can move within the second hole 336 so that it can move to a position within the fourth slide groove 335, or it can move to a position outside the fourth slide groove 335.

[0188] For example, when the rotating mechanism is in the folded state, at least a portion of the first stop block 229 can be located at the connecting portion of the first hole 236 and the third slide groove 235. In this way, the first stop block 229 can be positioned on the movement trajectory of the first swing arm 250 relative to the first fixed frame 230. When the folding electronic device is impacted (or dropped), the first stop block 229 can block the movement of the first swing arm 250, and the first link 220 can act as a stop, which helps to improve the phenomenon of reduced storage space.

[0189] Similarly, when the rotating mechanism is in the folded state, at least a portion of the second stop block 329 can be located at the connecting portion of the second hole 336 and the fourth slide groove 335. Likewise, the second stop block 329 can also be located on the movement trajectory of the second swing arm 350 relative to the second fixed frame 330, and the second connecting rod 320 can serve as a stop.

[0190] When the rotating mechanism is in the deployed state, at least a portion of the first stop block 229 is located within the first hole 236, and the first stop block 229 is also located outside the third slide groove 235. In this way, when the rotating mechanism is in the deployed state, the first connecting rod 220 can avoid the movement trajectory of the first swing arm 250.

[0191] Similarly, when the rotating mechanism is in the deployed state, at least a portion of the second stop block 329 is located within the second hole 336, and the second stop block 329 is also located outside the fourth slide groove 335. In this way, when the rotating mechanism is in the deployed state, the second link 320 can avoid the movement trajectory of the second swing arm 350.

[0192] The embodiments of this application do not limit the shape of the first hole 236 and the second hole 336. For example, the shape of the first hole 236 and the second hole 336 can be a strip hole. The first end 236a and the second end 236b of the first hole can be arranged in the extending direction of the first hole 236, and the first end 336a and the second end 336b of the second hole can be arranged in the extending direction of the second hole 336.

[0193] For example, when the rotating mechanism is in the deployed state: the distance between the first end 236a of the first hole and the main shaft 100 is equal to the distance between the second end 236b of the first hole and the main shaft 100, and the distance between the first end 236a of the first hole and the supporting plane S is less than the distance between the second end 236b of the first hole and the supporting plane S. The distance between the first end 336a of the second hole and the main shaft 100 is equal to the distance between the second end 336b of the second hole and the main shaft 100, and the distance between the first end 336a of the second hole and the supporting plane S is less than the distance between the second end 336b of the second hole and the supporting plane S.

[0194] For example, when the rotating mechanism is in the deployed state, the first end 236a of the first hole can be the top end of the first hole 236, and the second end 236b of the first hole can be the bottom end of the first hole 236. Similarly, the first end 336a of the second hole can be the top end of the second hole 336, and the second end 336b of the second hole can be the bottom end of the second hole 336. The extending direction of the first hole 236 and the extending direction of the second hole 336 can be parallel to a third direction.

[0195] Furthermore, the first end 236a of the first hole can communicate with the third slide groove 235, so that the movement trajectory of the first stop block 229 relative to the first fixed frame 230 and the movement trajectory of the third slider 251 of the first swing arm 250 relative to the first fixed frame 230 intersect. Similarly, the first end 336a of the second hole can communicate with the fourth slide groove 335, so that the movement trajectory of the second stop block 329 relative to the second fixed frame 330 and the movement trajectory of the fourth slider 351 of the second swing arm 350 relative to the second fixed frame 330 intersect.

[0196] For example, when the rotating mechanism is in the folded state, at least a portion of the first stop block 229 may be located at the first end 236a of the first hole, so that at least a portion of the first stop block 229 may be located at the communicating portion of the first hole 236 and the third slide groove 235. Similarly, when the rotating mechanism is in the folded state, at least a portion of the second stop block 329 may be located at the first end 336a of the second hole, so that at least a portion of the second stop block 329 may be located at the communicating portion of the second hole 336 and the fourth slide groove 335.

[0197] For example, when the rotating mechanism is in the deployed state, at least a portion of the first stop block 229 may be located at the second end 236b of the first hole, so that the first stop block 229 is located outside the third slide groove 235. Similarly, when the rotating mechanism is in the deployed state, at least a portion of the second stop block 329 may be located at the second end 336b of the second hole, so that the second stop block 329 is located outside the fourth slide groove 335.

[0198] During the transition of the rotating mechanism from the unfolded state to the folded state, the second end 220b of the first link can move relative to the first fixed frame 230 towards the support surface of the first fixed frame 230. That is, the first stop block 229 can move relative to the first fixed frame 230 towards the support surface of the first fixed frame 230. Similarly, the second end 320b of the second link can move relative to the second fixed frame 330 towards the support surface of the second fixed frame 330. In other words, the second stop block 329 can move relative to the second fixed frame 330 towards the support surface of the second fixed frame 330.

[0199] Conversely, during the transition of the rotating mechanism from a folded state to an unfolded state, the second end 220b of the first link can move relative to the first fixed frame 230 in a direction away from the support surface of the first fixed frame 230. That is, the first stop block 229 can move relative to the first fixed frame 230 in a direction away from the support surface of the first fixed frame 230. Similarly, the second end 320b of the second link can move relative to the second fixed frame 330 in a direction away from the support surface of the second fixed frame 330. In other words, the second stop block 329 can move relative to the second fixed frame 330 in a direction away from the support surface of the second fixed frame 330.

[0200] In some embodiments, continue to refer to Figure 12A When the rotating mechanism is in the deployed state: the first shaft 410 and the second shaft 510 can both be parallel to the support plane S. For example, the first shaft 410 can be parallel to the support surface of the first structural member, and the second shaft 510 can be parallel to the support surface of the second structural member. With this 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, thereby helping to reduce the thickness of the first rotating shaft assembly 200 and the second rotating shaft assembly 300.

[0201] Furthermore, when the rotating mechanism is in the deployed state: the first shaft 410 and the second shaft 510 can both be parallel to the second direction Y. This arrangement helps to reduce the space occupied by the first shaft 410 and the second shaft 510 in the first direction X and the third direction Z.

[0202] In some embodiments, when the rotating mechanism is in the deployed state: in the first direction X, the distance between the first end 224a of the first guide groove 224 and the first end 220a of the first connecting rod can be greater than the distance between the second end 224b of the first guide groove 224 and the first end 220a of the first connecting rod; and in the direction perpendicular to the support plane S, the distance between the first end 224a of the first guide groove 224 and the support plane S can be greater than the distance between the second end 224b of the first guide groove 224 and the support plane S. For example, the shape of the first guide groove 224 can be approximately strip-shaped, and the direction from the first end 224a of the first guide groove 224 to the second end 224b of the first guide groove 224 is the extension direction of the first guide groove 224.

[0203] Furthermore, through the above arrangement, the direction from the first end 224a of the first guide groove 224 to the second end 224b of the first guide groove 224 can approach the direction from the second end 220b of the first link to the first end 220a of the first link. This helps to reduce the space occupied by the first guide groove 224 at the second end 220b of the first link, thereby saving the space occupied by the first link 220.

[0204] Here and below, the direction A approaches the direction B, which can be understood as the direction A being parallel to the direction B, or the direction A being approximately parallel to the direction B. In some embodiments, when the rotating mechanism is in a folded state: the direction from the first end 224a of the first guide groove 224 to the second end 224b of the first guide groove 224 can be parallel to the first direction X.

[0205] In some embodiments, when the rotating mechanism is in a folded state, the extension direction of the first guide groove 224 is parallel to the first direction X, which helps to reduce the space occupied by the first guide groove 224 in the thickness direction of the first rotating shaft assembly 200 and helps to achieve the thinning of the first rotating shaft assembly 200.

[0206] Similarly, when the rotating mechanism is in the deployed state: in the first direction X, the distance between the first end 324a of the second guide groove 324 and the first end 320a of the second connecting rod can be greater than the distance between the second end 324b of the second guide groove 324 and the first end 320a of the second connecting rod; and in the direction perpendicular to the support plane S, the distance between the first end 324a of the second guide groove 324 and the support plane S can be greater than the distance between the second end 324b of the second guide groove 324 and the support plane S. For example, the shape of the second guide groove 324 can be approximately strip-shaped, and the direction from the first end 324a of the second guide groove 324 to the second end 324b of the second guide groove 324 is the extension direction of the second guide groove 324.

[0207] Furthermore, the direction from the first end 324a of the second guide groove 324 to the second end 324b of the second guide groove 324 can also approximate the direction from the second end 320b of the second link to the first end 320a of the second link. This arrangement helps to reduce the space occupied by the second guide groove 324 at the second end 320b of the second link, thereby saving space occupied by the second link 320.

[0208] In some embodiments, when the rotating mechanism is in a folded state: the direction from the first end 324a of the second guide groove 324 to the second end 324b of the second guide groove 324 can be parallel to the first direction X. With this arrangement, when the rotating mechanism is in a folded state, the extending direction of the first guide groove 224 is parallel to the first direction X, which helps to further reduce the space occupied by the second guide groove 324 in the thickness direction of the second rotating shaft assembly 300, and facilitates the thinning of the first rotating shaft assembly 200.

[0209] Combination Figure 13A and Figure 13BAs shown, during the transition of the rotating mechanism from the unfolded state to the folded state, the first shaft 410 can move relative to the first guide groove 224 in a direction from the first end 224a of the first guide groove 224 to the second end 224b of the first guide groove 224. Conversely, during the transition of the rotating mechanism from the folded state to the unfolded state, the first shaft 410 can move relative to the first guide groove 224 in a direction from the second end 324b of the first guide groove 224 to the first end 224a of the first guide groove 224.

[0210] Combination Figure 14A and Figure 14B As shown, during the transition of the rotating mechanism from the unfolded state to the folded state, the second shaft 510 can move relative to the second guide groove 324 in a direction from the first end 324a of the second guide groove 324 to the second end 324b of the second guide groove 324. Conversely, during the transition of the rotating mechanism from the folded state to the unfolded state, the second shaft 510 can move relative to the second guide groove 324 in a direction from the second end 324b of the second guide groove 324 to the first end 324a of the second guide groove 324.

[0211] 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.

[0212] As described in the above embodiments, the first end 220a of the first connecting rod and the first rotating member 210 can be rotatably connected via the third shaft 420. The first end 320a of the second connecting rod and the second rotating member 310 can be rotatably connected via the fourth shaft 520.

[0213] Figure 20A This is an exploded view of the structure of the first connecting rod, the first rotating member 210, the second connecting rod, and the second rotating member 310 from a first perspective, according to an embodiment of this application. Figure 20B This is an exploded view of the first connecting rod, the first rotating member 210, the second connecting rod, and the second rotating member 310 from a second perspective according to an embodiment of this application. The second perspective can be a direction parallel to and opposite to the first perspective.

[0214] Furthermore, the first end 220a of the first connecting rod may include a first connecting portion 227a and a second connecting portion 227b spaced apart, and the first rotating member may include a first mating portion 219a, a second mating portion 219b, and a third mating portion 219c spaced apart. When the rotating mechanism is in the unfolded state, in the second direction, the third shaft passes sequentially through the first mating portion 219a, the first connecting portion 227a, the second mating portion 219b, the second connecting portion 227b, and the third mating portion 219c. Through the above arrangement, the first mating portion 219a, the first connecting portion 227a, the second mating portion 219b, the second connecting portion 227b, and the third mating portion 219c can be rotatably connected by the third shaft 420.

[0215] For example, when the rotating mechanism is in the deployed state, the third end 210c and the fourth end 210d of the first rotating member are arranged along the first direction X. The orthographic projections of the third end 210c of the first rotating member, the first end 220a of the first connecting rod, and the second end 220b of the first connecting rod on the supporting plane S are arranged sequentially along the first direction X. Since both the first rotating member 210 and the first connecting rod 220 are three-dimensional structures, the third end 210c of the first rotating member, the first end 220a of the first connecting rod, and the second end 220b of the first connecting rod can have different heights in the third direction Z.

[0216] In some embodiments, the first end 220a of the first connecting rod is rotatably connected to the first rotating member 210, which may include: the fourth end 210d of the first rotating member being rotatably connected to the first end 220a of the first connecting rod.

[0217] For example, the fourth end 210d of the first rotating member may include a first mating part 219a, a second mating part 219b, and a third mating part 219c arranged at intervals. When the rotating mechanism is in the unfolded state, the first mating part 219a, the first connecting part 227a, the second mating part 219b, the second connecting part 227b, and the third mating part 219c are arranged sequentially in the second direction Y. The first mating part 219a, the first connecting part 227a, the second mating part 219b, the second connecting part 227b, and the third mating part 219c are all provided with holes so that the third shaft 420 can be rotatably connected to the first mating part 219a, the first connecting part 227a, the second mating part 219b, the second connecting part 227b, and the third mating part 219c, respectively.

[0218] With the above configuration, when the electronic device is in a folded state and is subjected to an impact (or dropped), the first rotating member 210 may bend and deform under the impact force. In this case, the two ends of the third shaft 420 can respectively bear the deformation force from the first mating part 219a and the third mating part 219c, and the middle part of the third shaft 420 can bear the deformation force from the second mating part 219b. Since both ends and the middle part of the third shaft 420 can bear the deformation force from the first rotating member 210, this helps to improve the problem of deformation or breakage of the third shaft 420 caused only by forces on its two ends, and improves the structural reliability of the third shaft 420.

[0219] Similarly, the first end 320a of the second connecting rod includes a third connecting portion 327a and a fourth connecting portion 327b spaced apart, and the second rotating member 310 includes a fourth mating portion 319a, a fifth mating portion 319b, and a sixth mating portion 319c spaced apart. When the rotating mechanism is in the unfolded state, in the second direction Y, the fourth shaft 520 passes sequentially through the fourth mating portion 319a, the third connecting portion 327a, the fifth mating portion 319b, the fourth connecting portion 327b, and the sixth mating portion 319c. Through the above arrangement, the fourth mating portion 319a, the third connecting portion 327a, the fifth mating portion 319b, the fourth connecting portion 327b, and the sixth mating portion 319c can be rotatably connected through the fourth shaft 520.

[0220] In some embodiments, when the rotating mechanism is in the deployed state, the third end 310c of the second rotating member and the fourth end 310d of the second rotating member are arranged along the first direction X. The orthographic projections of the third end 310c of the second rotating member, the first end 320a of the second connecting rod, and the second end 320b of the second connecting rod onto the supporting plane S are arranged sequentially along the first direction X. Since both the second rotating member 310 and the second connecting rod 320 are three-dimensional structures, the third end 310c of the second rotating member, the first end 320a of the second connecting rod, and the second end 320b of the second connecting rod can have different heights in the third direction Z.

[0221] In some embodiments, the first end 320a of the second connecting rod is rotatably connected to the second rotating member 310, and may further include: the first end 320a of the second connecting rod and the second rotating member 310 may be rotatably connected through the fourth shaft 520 and the second mating hole 325.

[0222] For example, the fourth end 310d of the second rotating member may include a fourth mating part 319a, a fifth mating part 319b, and a sixth mating part 319c arranged at intervals. When the rotating mechanism is in the unfolded state, the fourth mating part 319a, the fifth mating part 319b, and the sixth mating part 319c are arranged sequentially in the second direction Y. The fourth mating part 319a, the third connecting part 327a, the fifth mating part 319b, the fourth connecting part 327b, and the sixth mating part 319c are all provided with holes so that the fourth shaft 520 can be rotatably connected to the fourth mating part 319a, the third connecting part 327a, the fifth mating part 319b, the fourth connecting part 327b, and the sixth mating part 319c, respectively.

[0223] With the above configuration, the deformation force from the first rotating member 210 can be shared at both ends and the middle of the fourth shaft, which helps to improve the problem of deformation or breakage of the fourth shaft 520 caused by the force being applied only at both ends of the fourth shaft 520, and helps to improve the structural reliability of the fourth shaft 520.

[0224] In some embodiments, continue to refer to Figure 12A When the rotating mechanism is in the deployed state: the third shaft 420 and the fourth shaft 520 can also be parallel to the support plane S. For example, the third shaft 420 can be parallel to the support surface of the first structural member, and the fourth shaft 520 can be parallel to the support surface of the second structural member. With the above arrangement, in the direction perpendicular to the support plane S, it is beneficial to reduce the space occupied by the third shaft 420 and the fourth shaft 520, thereby helping to reduce the thickness of the first rotating shaft assembly 200 and the second rotating shaft assembly 300.

[0225] Furthermore, when the rotating mechanism is in the deployed state: the extension direction of the third shaft 420 (which is also the extension direction of the first shaft L1) can be parallel to the second direction Y; the extension direction of the fourth shaft 520 (which is also the extension direction of the second shaft L2) can be parallel to the second direction Y. Through the above arrangement, in the first direction X and the third direction Z, it is beneficial to reduce the space occupied by the first shaft 410 and the second shaft 510.

[0226] Figure 21 This is a structural diagram illustrating the transition between an unfolded state and a folded state of a first link and a second link, as provided in an embodiment of this application.

[0227] Reference Figure 21 As shown, by combining the positional relationship of the first axis, the second axis, the third axis 420 and the fourth axis 520, it can be seen that during the transition between the unfolded state and the folded state of the rotating mechanism, the extension direction of the first axis 410 can be parallel to the extension direction of the third axis 420, and the extension direction of the second axis can be parallel to the extension direction of the fourth axis 520.

[0228] With the above configuration, the space occupied by the first connecting rod 220 in the thickness direction is reduced, facilitating the thinning of the first rotating shaft assembly 200. The extension direction of the second shaft 510 can be parallel to the extension direction of the fourth shaft 520. With the above configuration, the space occupied by the second connecting rod 320 in the thickness direction is reduced, facilitating the thinning of the second rotating shaft assembly 300.

[0229] Since both the first rotating shaft assembly 200 and the second rotating shaft assembly 300 rotate relative to the main shaft 100, the thickness direction of both the first rotating shaft assembly 200 and the second rotating shaft assembly 300 changes during the transition between the unfolded state and the folded state of the rotating mechanism.

[0230] In some examples, the thickness direction of the first rotating shaft assembly 200 may be perpendicular to the extension direction of the first shaft 410, and also perpendicular to the first direction X. Similarly, the thickness direction of the second rotating shaft assembly 300 may be perpendicular to the extension direction of the second shaft 510, and also perpendicular to the first direction X. Furthermore, when the rotating mechanism is in the unfolded state, the thickness directions of the first rotating shaft assembly 200 and the second rotating shaft assembly 300 may be perpendicular to the support plane S, for example, the third direction Z. When the rotating mechanism is in the folded state, the thickness directions of the first rotating shaft assembly 200 and the second rotating shaft assembly 300 may be parallel to the support plane S, for example, the second direction Y.

[0231] During the transition between the unfolded and folded states of the rotating mechanism, the distance between the first shaft 410 and the third shaft 420 in the thickness direction of the first rotating shaft assembly 200 changes, and the distance between the second shaft 510 and the fourth shaft 520 in the thickness direction of the second rotating shaft assembly 300 changes.

[0232] For example, when the rotating mechanism is in the deployed state, in the direction perpendicular to the support plane S (i.e., the third direction Z), 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. The distance between the first axis 410 and the third axis 420 is the first distance D1. 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. The distance between the second axis 510 and the fourth axis 520 is the second distance D2.

[0233] During the transition of the rotating mechanism from the unfolded state to the folded state, in the thickness direction of the first rotating shaft assembly 200, the distance between the first shaft 410 and the third shaft 420 is less than the first distance D1, and in the thickness direction of the second rotating shaft assembly 300, the distance between the second shaft 510 and the fourth shaft 520 is less than the second distance D2.

[0234] When the rotating mechanism is in the folded state, in the thickness direction of the first rotating shaft assembly 200, the distance D3 between the first shaft 410 and the third shaft 420 is less than the first distance D1, and in the thickness direction of the second rotating shaft assembly 300, the distance D4 between the second shaft 510 and the fourth shaft 520 is less than the second distance D2.

[0235] With the above settings, during the transition of the rotating mechanism from the unfolded state to the folded state, the distance between the first axis 410 and the third axis 420 in the thickness direction of the first rotating shaft assembly 200 becomes smaller, and the distance between the second axis 510 and the fourth axis 520 in the thickness direction of the second rotating shaft assembly 300 becomes smaller, which is beneficial to achieving the thinning and lightening of foldable electronic devices.

[0236] In some examples, when the rotating mechanism is in the folded state, the central axis of the first shaft 410 (i.e., the first axis L1) can coincide with the orthographic projection of the central axis of the third shaft 420 in the plane containing the third direction Z and the second direction Y. The distance D3 between the first shaft 410 and the third shaft 420 in the thickness direction of the first rotating shaft assembly 200 can be 0.

[0237] Alternatively, the central axis of the third axis 420 (i.e., the first axis L1) can be located between the central axis of the first axis 410 and the flexible screen. Specifically, in the plane containing the third direction Z and the second direction Y, the orthographic projection of the central axis of the first axis 410 (i.e., the first axis L1) and the orthographic projection of the central axis of the third axis 420 may not coincide, and the distance D3 between the first axis 410 and the third axis 420 in the thickness direction of the first rotating shaft assembly 200 may not be zero.

[0238] With the above settings, during the transition of the rotating mechanism from the unfolded state to the folded state, the distance between the first shaft 410 and the third shaft 420 in the thickness direction of the first rotating shaft assembly 200 gradually decreases. This distance does not decrease to 0 and then gradually increase, which is beneficial to further reduce the space occupied by the first link 220 in the thickness direction of the first rotating shaft assembly 200.

[0239] In some examples, when the rotating mechanism is in the folded state, the central axis of the fourth axis 520 (i.e., the second axis L2) can coincide with the orthographic projection of the central axis of the second axis 510 in the plane containing the third direction Z and the second direction Y. In the thickness direction of the second rotating shaft assembly 300, the distance D4 between the second axis 510 and the fourth axis 520 can be 0.

[0240] Alternatively, the central axis of the fourth axis 520 (i.e., the second axis L2) can be located between the central axis of the second axis 510 and the flexible screen. The orthographic projections of the central axes of the second axis 510 and the fourth axis 520 onto the plane containing the third direction Z and the second direction Y may not coincide, and the distance D4 between the second axis 510 and the fourth axis 520 in the thickness direction of the second rotating shaft assembly 300 may not be zero.

[0241] With the above settings, during the transition of the rotating mechanism from the unfolded state to the folded state, the distance between the second shaft 510 and the fourth shaft 520 in the thickness direction of the second rotating shaft assembly 300 gradually decreases. This distance does not decrease to 0 and then gradually increase, which is beneficial to further reduce the space occupied by the second link 320 in the thickness direction of the second rotating shaft assembly 300.

[0242] In addition, in some other examples, refer to Figure 21 When the rotating mechanism is in the folded state, in the plane containing the third direction Z and the second direction Y, the orthographic projection of the central axis of the third axis 420 (i.e., the first axis L1) can be located on the side where the orthographic projection of the central axis of the first axis 410 is opposite to the orthographic projection of the flexible screen, and the orthographic projection of the central axis of the fourth axis 520 (i.e., the second axis L2) can be located on the side where the orthographic projection of the central axis of the second axis 510 is opposite to the orthographic projection of the flexible screen.

[0243] With the above configuration, during the transition of the rotating mechanism from the unfolded state to the folded state, the distance between the first shaft 410 and the third shaft 420 in the thickness direction of the first rotating shaft assembly 200 will first decrease and then increase, and the distance between the second shaft 510 and the fourth shaft 520 in the thickness direction of the second rotating shaft assembly 300 will first decrease and then increase. However, when the rotating mechanism is in the folded state, since the distance between the first shaft 410 and the third shaft 420 and the distance between the second shaft 510 and the fourth shaft 520 are both small, it is beneficial to reduce the space occupied by the first connecting rod 220 in the thickness direction of the first rotating shaft assembly 200 and the space occupied by the second connecting rod 320 in the thickness direction of the second rotating shaft assembly 300.

[0244] Figure 22A for Figure 18 A magnified view of a section at W3. Figure 22A The structure can be shown with the first connecting rod and the first rotating member in the deployed state. Figure 22B for Figure 17 A magnified view of a section at point W1. Figure 22B The structure of the first link and the first rotating member in the folded state can be shown.

[0245] Reference Figure 22A and Figure 22B As shown, in some embodiments, the first end 220a of the first link can slide relative to the first rotating member 210 along the extension direction of the first axis L1.

[0246] During the transition of the rotating mechanism from the unfolded state to the folded state, the first end 220a of the first link moves relative to the first rotating member 210 along a direction parallel to the first axis L1 and from the main shaft 100 toward the first fixed frame 230.

[0247] During the transition of the rotating mechanism from the folded state to the unfolded state, the first end 220a of the first link moves relative to the first rotating member 210 along a direction parallel to the first axis L1 and from the first fixed frame 230 toward the main shaft 100.

[0248] For example, when the rotating mechanism is in the unfolded state: the distance between the first end of the third shaft and the main shaft 100 is less than the distance between the second end of the third shaft and the main shaft 100. During the transition of the rotating mechanism from the unfolded state to the folded state, the first end 220a of the first link moves relative to the first rotating member 210 in the direction from the first end of the third shaft to the second end of the third shaft. During the transition of the rotating mechanism from the folded state to the unfolded state, the first end 220a of the first link moves relative to the first rotating member 210 in the direction from the second end of the third shaft to the first end of the third shaft.

[0249] With the above settings, when the rotating mechanism is transitioning from the unfolded state to the folded state, the first link 220 slides away from the main shaft 100 relative to the first rotating member 210. Correspondingly, when the rotating mechanism is transitioning from the folded state to the unfolded state, the first link 220 slides towards the main shaft 100 relative to the first rotating member 210.

[0250] Figure 23A for Figure 18 A magnified view of the area at W4 in the middle. Figure 23A The structure can be shown with the second link and the second rotating member in the deployed state. Figure 23B for Figure 17 A magnified view of the area at W2 in the middle. Figure 23B The structure of the second link and the second rotating member in the folded state can be shown.

[0251] Reference Figure 23A and Figure 23B As shown, in some embodiments, the first end 320a of the second link can slide relative to the second rotating member 310 along the extension direction of the second axis L2.

[0252] During the transition of the rotating mechanism from the unfolded state to the folded state, the first end 320a of the second link moves relative to the second rotating member 310 along a direction parallel to the second axis L2 and from the main shaft 100 toward the second fixed frame 330.

[0253] For example, when the rotating mechanism is in the unfolded state: in the second direction Y, the distance between the first end of the fourth shaft and the main shaft 100 is less than the distance between the second end of the fourth shaft and the main shaft 100. During the transition of the rotating mechanism from the unfolded state to the folded state, the first end 320a of the second link moves relative to the second rotating member 310 in the direction from the first end of the fourth shaft to the second end of the fourth shaft. During the transition of the rotating mechanism from the folded state to the unfolded state, the first end 320a of the second link moves relative to the second rotating member 310 in the direction from the second end of the fourth shaft to the first end of the fourth shaft.

[0254] With the above configuration, when the rotating mechanism transitions from the unfolded state to the folded state, the second link 320 slides away from the main shaft 100 relative to the second rotating member 310. Correspondingly, when the rotating mechanism transitions from the folded state to the unfolded state, the second link 320 slides closer to the main shaft 100 relative to the second rotating member 310.

[0255] In some embodiments, combined with Figure 20A and Figure 20B The first rotating member 210 may include a first helical surface 218, and the first end 220a of the first connecting rod includes a second helical surface 228 that cooperates with the first helical surface 218. The first helical surface 218 and the second helical surface 228 have the same direction of rotation.

[0256] For example, the first helical surface 218 and the second helical surface 228 may be arranged around the third axis 420, and the first helical surface 218 and the second helical surface 228 may be arranged along the extension direction of the third axis 420.

[0257] During the transition between the unfolded and folded states of the rotating mechanism, as the first end 220a of the first link rotates relative to the first rotating member 210, it also slides relative to the first rotating member 210, causing the first end 220a of the first link to helically move relative to the first rotating member 210. Similarly, the first end 320a of the second link helically moves relative to the second rotating member 310.

[0258] With the above configuration, the cooperation of the first helical surface 218 and the second helical surface 228 prevents a large relative sliding space between the first end 220a of the first connecting rod and the first rotating member 210. This further prevents the first end 220a of the first connecting rod from wobbling relative to the first rotating member 210 when the rotating mechanism is subjected to impact.

[0259] During the transition between the folded and unfolded states of the rotating mechanism, the distance between the first helical surface 218 and the second helical surface 228 can remain unchanged.

[0260] In some embodiments, the second rotating member 310 includes a third helical surface 318, and the first end 320a of the second connecting rod includes a fourth helical surface 328 that cooperates with the third helical surface 318. The third helical surface 318 and the fourth helical surface 328 have the same direction of rotation, and the third helical surface 318 and the first helical surface 218 have opposite directions of rotation.

[0261] For example, the third helical surface 318 and the fourth helical surface 328 may be arranged around the fourth axis 520, and the third helical surface 318 and the fourth helical surface 328 may be arranged along the extension direction of the fourth axis 520.

[0262] Similarly, by setting the third helical surface 318 and the fourth helical surface 328, it is beneficial to prevent the first end 320a of the second connecting rod from wobbling relative to the second rotating member 310 when the rotating mechanism is subjected to impact. During the transition between the folded state and the unfolded state of the rotating mechanism, the distance between the third helical surface 318 and the fourth helical surface 328 can remain unchanged.

[0263] Continue to refer to Figure 6 In some embodiments, the first rotating shaft assembly 200 may further include a first support plate 240, the first support plate 240 and the first rotating member 210 may be slidably connected, and the first support plate 240 may also be rotatably connected to the first fixing frame 230.

[0264] In some embodiments, the second rotating shaft assembly 300 may further include a second support plate 340, the second support plate 340 and the second rotating member 310 may be slidably connected, and the second support plate 340 may also be rotatably connected to the second fixing frame 330.

[0265] With the above settings, the rotation mechanism can change the position of the first support plate 240 and the second support plate 340 relative to the main shaft 100 during the transition between the unfolded state and the folded state.

[0266] When the rotating mechanism is in the extended state, the first rotating shaft assembly 200, the main shaft 100, and the second rotating shaft assembly 300 together form a supporting plane S, including: a first support plate 240, a first fixing frame 230, the main shaft 100, the second support plate 340, and the second fixing frame 330. This arrangement helps to improve the support effect of the first rotating shaft assembly 200 and the second rotating shaft assembly 300 on the flexible screen.

[0267] When the rotating mechanism is in the folded state, the minimum distance between the support surfaces of the first support plate 240 and the second support plate 340 along the second direction Y is greater than or equal to the distance between the support surfaces of the first fixed frame 230 and the second fixed frame 330 along the second direction Y. Specifically, when the rotating mechanism is in the folded state, the distance between the support surfaces of the first support plate 240 and the second support plate 340 along the second direction Y gradually increases in the direction closest to the main shaft 100.

[0268] With the above configuration, the flexible screen can be bent into a teardrop shape or a near-teardrop shape within the space P enclosed by the first fixed frame 230, the second fixed frame 330, the first support plate 240, the second support plate 340, the first rotating component 210, the second rotating component 310, and the main shaft 100, thus avoiding excessive compression of the flexible screen, reducing the stress on the flexible screen, and improving the reliability of the flexible screen.

[0269] Figure 24 This is an exploded view of the structure of a rotating mechanism provided in an embodiment of this application from another perspective. Figure 24 The viewing direction can be roughly as follows: when the rotating mechanism is in the unfolded state, the direction is from the main shaft to the flexible screen.

[0270] Reference Figure 24 and Figure 7 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 extension 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.

[0271] 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.

[0272] The third guide groove 213 and the fourth guide groove 313 can be strip-shaped grooves. Alternatively, in some other embodiments, the third guide groove 213 and the fourth guide groove 313 can also be arc-shaped grooves, which is not limited in this application embodiment.

[0273] With the above configuration, when the first mating shaft 216 moves along the extension direction of the third guide groove 213, the first support plate 240 and the first rotating member 210 slide relative to each other. When the second mating shaft 316 moves along the extension direction of the fourth guide groove 313, the second support plate 340 and the second rotating member 310 slide relative to each other.

[0274] In some embodiments, the first support plate 240 and the first fixing frame 230 can be rotatably connected by a third arc-shaped slider 241 and a third arc-shaped slide groove 237, wherein the first support plate 240 may include the third arc-shaped slider 241, and the first fixing frame 230 may include the third arc-shaped slide groove 237. The second support plate 340 and the second fixing frame 330 can be rotatably connected by a fourth arc-shaped slider 341 and a fourth arc-shaped slide groove 337, wherein the second support plate 340 may include the fourth arc-shaped slider 341, and the second fixing frame 330 may include the fourth arc-shaped slide groove 337.

[0275] Figure 25 An exploded view of the assembly structure of a first swing arm, a second swing arm, and a main shaft provided in an embodiment of this application.

[0276] Based on the above structure, the main shaft 100 may include a plurality of mounting shafts arranged sequentially along the second direction Y, and all mounting shafts extend along the first direction X. The first end 250a of the first swing arm may be sleeved on one mounting shaft so that the first end 250a of the first swing arm can be rotatably connected to the main shaft 100, and the first end 350a of the second swing arm may be sleeved on another mounting shaft so that the first end 350a of the second swing arm can be rotatably connected to the main shaft 100.

[0277] The spindle 100 may further include an elastic element 150 and a damping slider 160. The elastic element 150 may be disposed on the spindle 100 along a first direction X, and the damping slider 160 may be slidably connected to the spindle 100 along the first direction X. For example, the elastic element 150 may be sleeved on a mounting shaft, and the damping slider 160 may be slidably connected to the mounting shaft.

[0278] The first swing arm 250 and the second swing arm 350 together constitute a swing arm assembly. In an embodiment where there are two damping sliders 160, the number of swing arm assemblies in the rotating mechanism can be two. One swing arm assembly is located on the side of a damping slider 160 facing away from the first end of the elastic member 150, and the other swing arm assembly is located on the side of a damping slider 160 facing away from the second end of the elastic member 150. The following description uses only one swing arm assembly and one corresponding damping slider 160 as an example.

[0279] Furthermore, the first end 250a of the first swing arm 250 may include a first concave-convex surface 258, the damping slider 160 may include a second concave-convex surface 161 that cooperates with the first concave-convex surface 258, the first end 350a of the second swing arm 350 may include a third concave-convex surface 358, and the damping slider 160 may include a fourth concave-convex surface 162 that cooperates with the third concave-convex surface 358.

[0280] When the first swing arm 250 rotates relative to the main shaft 100, it also rotates relative to the first mounting shaft 131. Since the first concave-convex surface 258 of the first swing arm 250 engages with the second concave-convex surface 161 of the damping slider 160, the first swing arm 250 drives the damping slider 160 to slide relative to the first mounting shaft 131 along the first direction X. The damping slider 160 then drives the elastic element 150 to compress and deform. The elastic restoring force of the elastic element 150 acts as a damping force, thus providing a damping effect when the first swing arm 250 rotates relative to the main shaft 100. Similarly, when the second swing arm 350 rotates relative to the main shaft 100, it drives the damping slider 160 to slide relative to the first mounting shaft 131 along the first direction X, causing the elastic element 150 to compress and deform. The elastic restoring force of the elastic element 150 also acts as a damping force, thus providing a damping effect when the first swing arm 250 rotates relative to the main shaft 100.

[0281] In some embodiments, the first end 250a of the first swing arm 250 may further include a first gear 255, and the main shaft 100 may further include a second gear 142 meshing with the first gear 255. The first end 350a of the second swing arm 350 may further include a third gear 355, and the main shaft 100 may further include a fourth gear 143 meshing with the third gear 355. The second gear 142 also meshes with the fourth gear 143.

[0282] When the first swing arm 250 rotates relative to the main shaft 100, the first gear 255 drives the second gear 142 to rotate, which in turn drives the fourth gear 143 to rotate. The fourth gear 143 then drives the third gear 355 to rotate, causing the second swing arm 350 to rotate relative to the main shaft 100. Through this configuration, the first swing arm 250 rotates relative to the main shaft 100 while the second swing arm 350 rotates relative to the main shaft 100, thus achieving synchronous movement of the first and second swing arms 250.

[0283] 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.

[0284] 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.
