Description

Technical Field

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

[0002] With the continuous development of flexible display technology, it has been widely used in various foldable electronic devices. Foldable electronic devices often include a folding mechanism to support the flexible display. In traditional inward-folding electronic devices, due to the structural design of the inward folding mechanism itself, the flexible display is prone to collisions with other structural components during the relative unfolding and folding processes, leading to partial failure of the flexible display and a shorter lifespan, thus affecting the user experience. Summary of the Invention

[0003] This application provides a foldable electronic device and folding mechanism with a long service life of flexible display screen.

[0004] In a first aspect, a foldable electronic device is provided. The foldable electronic device includes a folding device and a flexible display screen; the folding device includes a first housing, a second housing, and a folding mechanism, the folding device having an open state and a closed state, the folding mechanism including a first component, a second component, a main shaft, and a support plate, the first component connecting the main shaft and the first housing, the second component connecting the main shaft and the second housing, the first component having a first support surface, the second component having a second support surface, both the first support surface and the second support surface facing the flexible display screen; the flexible display screen includes a first flat portion, a bent portion, and a second flat portion connected sequentially, the first flat portion being fixedly connected to the first housing, the second flat portion being fixedly connected to the first housing, and so on. The second housing is fixedly connected; the support piece is located between the main shaft and the flexible display screen. The support piece includes a first fixing part, a connecting part, and a second fixing part connected in sequence. The first fixing part is fixedly connected to the first support surface or the first housing, and the second fixing part is fixedly connected to the second support surface or the second housing. In the open state, the first housing and the second housing are relatively flattened, the first support surface and the second support surface are relatively flattened, the support piece and the flexible display screen are both flattened, and the support piece supports the bent part of the flexible display screen. In the closed state, the first housing and the second housing are relatively folded, the flexible display screen and the support piece are both bent, and the support piece fits into the bent part of the flexible display screen.

[0005] It is understood that in this embodiment, the electronic device is configured such that the flexible display screen is fixed only to the first and second housings, and a support plate is provided between the flexible display screen and the main shaft. Both ends of the support plate can be fixed ends; one end is used to fix the first support surface or the first housing of the folding mechanism, and the other end is used to fix the second support surface or the second housing of the folding mechanism. The support plate is in contact with the flexible display screen. Thus, when the electronic device is in the open state, the support plate can effectively cover the folding mechanism, providing a relatively flat support environment for the flexible display screen. When the electronic device switches from the open state to the closed state, the movement of the folding device can drive the two fixed ends of the support plate to move, causing the support plate to deform so that the connecting part of the support plate can be arc-shaped. At this time, the flexible display screen can be folded relative to the support plate under the movement of the folding device. The bent part of the flexible display screen can bend towards the support plate under its own rebound force and fits the support plate over a large area, so that the shape of the inner bent part of the flexible display screen can be similar to the shape of the connecting part of the support plate, both being arc-shaped.

[0006] In other words, the support plate in this embodiment can not only cover the folding mechanism in the open state, providing a relatively flat support environment for the flexible display screen and ensuring the flatness of the folding mechanism in the unfolded state, but also wrap around and fit the inner bending part of the flexible display screen in the closed state. This allows the inner bending part of the flexible display screen to fit against the support plate over a large area, forming a relatively rounded arc shape. This avoids excessive natural drooping of the flexible display screen when the electronic device is in the closed state, which could cause creases in the flexible display screen due to contact with the main shaft and affect the user experience.

[0007] Secondly, in typical foldable electronic devices, the support plate has one fixed end attached to one of the support plates, while the other end is a free end extending to another support plate. When the electronic device switches from an open to a closed state, the movement of the folding mechanism can move the two support plates, causing the flexible display screen to deform. Under its own rebound force, the flexible display screen bends along the direction of the support plate, causing the support plate to bend to conform to the shape of the flexible display screen. However, the design of one fixed end and the other free end of the support plate makes it prone to fatigue after repeated bending after multiple folds of the electronic device. This causes the free end of the support plate to deviate from its designed movement trajectory, making it more likely to collide with the flexible display screen and produce a scraping sound, affecting the user experience.

[0008] In this embodiment, both ends of the support piece (i.e., the first fixing part and the second fixing part in this embodiment) are fixed ends. Even if the electronic device is folded multiple times, the support piece can still move along the designed motion trajectory under the movement of the first support plate and the second support plate, and fit the flexible display screen. This can effectively avoid the problem of the support piece rubbing against the flexible display screen due to fatigue caused by multiple bending, and effectively improve the user experience.

[0009] In one possible implementation, the support piece is an integral structural component.

[0010] Understandably, compared to typical electronic devices that include two support plates fixed to support plates on either side of the main shaft, the flexible display screen in the open state can be relatively flattened to cover other components of the folding mechanism and provide a relatively flat support environment when closed. However, in the closed state, the two support plates move away from each other as the support plates on either side of the main shaft move, with the two support plates facing each other and spaced apart, located on opposite sides of the bent portion of the flexible display screen. This makes it easy for the bent portion of the flexible display screen to collide with the main shaft when the electronic device falls in the closed state, causing partial failure of the flexible display screen and the appearance of small black spots, affecting the user experience.

[0011] In this embodiment, the support piece is an integral structural component, with both ends serving as fixed ends. One end is used to fix the first support surface or first housing of the folding mechanism, and the other end is used to fix the second support surface or second housing of the folding mechanism. That is, the support piece in this embodiment can extend across the main shaft from one side to the other. Thus, when the electronic device is in a closed state, the support piece can separate the flexible display screen from the main shaft, wrapping and conforming to the flexible display screen. This effectively prevents the flexible display screen from colliding with the main shaft when the electronic device falls in a closed state, extending the lifespan of the flexible display screen and improving the user experience.

[0012] In one possible implementation, the bending portion of the flexible display screen includes a first outer bending portion, a first non-bending portion, an inner bending portion, a second non-bending portion, and a second outer bending portion connected in sequence. The first outer bending portion is connected to a first straight portion, and the second outer bending portion is connected to a second straight portion. In the closed state, the connecting portion of the support sheet is attached to the inner bending portion of the flexible display screen.

[0013] It is understandable that, in this embodiment, when the electronic device is in the open state, the width of the connecting portion of the support plate can be greater than the width of the inner bend of the flexible display screen. By setting the width of the connecting portion of the support plate to be greater than the width of the bend of the flexible display screen, the support plate can better fit and support the inner bend of the flexible display screen over a large area. This allows the support plate to not only cover other structures of the folding mechanism in the open state and provide a relatively flat supporting environment for the inner bend of the flexible display screen, ensuring the flatness of the folding mechanism in the unfolded state, but also to better wrap and fit the inner bend of the flexible display screen in the closed state. This allows the inner bend of the flexible display screen to present a more rounded arc shape under the action of the support plate, thereby preventing the inner bend of the flexible display screen from drooping excessively when the electronic device is closed, thus avoiding creases caused by contact with the main shaft or partial failure of the inner bend due to collision with the main shaft, resulting in small black spots and affecting the user experience.

[0014] In one possible implementation, the flexible display screen's bending portion includes an inner bending portion, which is disposed opposite to the main shaft; in the closed state, the connecting portion of the support sheet is fitted to the inner bending portion of the flexible display screen.

[0015] In this way, the support plate can fit and support the inner bend of the flexible display screen better, avoiding collision between the inner bend of the flexible display screen and the main shaft.

[0016] In one possible implementation, in the open state, the width of the connecting portion of the support sheet is greater than the width of the inner bend of the flexible display screen.

[0017] In this way, by setting the width of the connecting part of the support plate to be greater than the width of the bending part of the flexible display screen, the support plate has a wider area that can be freely bent. This allows it to better fit and support the inner bending part of the flexible display screen over a large area. The support plate can not only cover other structures of the folding mechanism when open, providing a relatively flat supporting environment for the inner bending part of the flexible display screen and ensuring the flatness of the folding mechanism in the unfolded state, but also better wrap and fit the inner bending part of the flexible display screen when closed. This allows the inner bending part of the flexible display screen to present a more rounded arc shape under the action of the support plate. This avoids excessive natural sag of the inner bending part of the flexible display screen when the electronic device is closed, which could cause creases in the flexible display screen due to contact with the main shaft, or cause partial failure of the inner bending part due to collision with the main shaft, resulting in small black spots and affecting the user experience.

[0018] In one possible implementation, the support sheet is made of stainless steel, fiber cloth, or polycarbonate. This allows the support sheet to be easily bent while maintaining a certain level of structural strength.

[0019] In one possible implementation, the thickness of the support sheet is less than or equal to 0.1 mm. This makes the support sheet thinner and easier to bend.

[0020] In one possible implementation, the first component includes a first support plate, a first fixing frame, and a first arc arm. The first fixing frame is fixed to the first housing. The first support plate includes a support body and a first connecting part. The surface of the support body facing the flexible display screen forms a first support surface. The first connecting part is fixedly connected to the side of the support body facing away from the flexible display screen and is hinged to the first fixing frame. The first arc arm includes a first rotating end and a second rotating end. The first rotating end of the first arc arm is rotatably connected to the first fixing frame, and the second rotating end of the first arc arm is rotatably connected to the main shaft.

[0021] In this way, the first support plate can cover the first fixing frame and the first arc arm, and the surface of the first support plate facing the flexible display screen can serve as the first support surface to better support the flexible display screen.

[0022] In one possible implementation, the first component further includes a first rotating shaft, and the first connecting portion of the first support plate is hinged to the first fixing frame via the first rotating shaft.

[0023] It is understood that in this embodiment, the first support plate is hinged to the first fixed frame. In this case, a solid shaft rotational connection structure can be formed between the first support plate and the first fixed frame. This solid shaft rotational connection structure helps reduce the play generated when the first support plate moves relative to the first fixed frame, improves the movement accuracy of the first support plate, and prevents the first support plate from wobbling due to play. This wobbling would occupy the space of the flexible display screen, causing the flexible display screen to collide with the first support plate during a drop, resulting in partial failure of the flexible display screen and the generation of small black dots, affecting the user experience.

[0024] In one possible implementation, the first rotating end of the first arc arm is hinged to the first fixed frame via a first rotating shaft.

[0025] In this way, on the one hand, a solid shaft rotational connection structure can be formed between the first arc arm and the first fixed frame, which helps to reduce the play generated when the first arc arm moves relative to the first fixed frame, improve the motion accuracy of the first support plate, and make the trajectory control of the first support plate more precise; on the other hand, the first support plate and the first arc arm are rotatably connected to the first fixed frame through the same solid shaft, which helps to simplify the mechanism and simplify the assembly process.

[0026] In one possible implementation, the first component further includes a second arc arm, which includes a first rotating end and a second rotating end. The first rotating end of the second arc arm is rotatably connected to the first fixed frame, and the second rotating end of the second arc arm is rotatably connected to the main shaft. The first arc arm and the second arc arm are located at both ends of the first fixed frame, and the arrangement direction of the first arc arm and the second arc arm is parallel to the length extension direction of the folding mechanism.

[0027] It is understood that the first component in this embodiment includes a first arc arm and a second arc arm. Both the first and second arc arms can connect to the first fixed frame and the main shaft, and the first and second arc arms can respectively connect to the two ends of the first fixed frame. In this way, when the first fixed frame moves relative to the main shaft, its movement is relatively smooth and will not cause lateral flipping. This effectively avoids the first fixed frame colliding with the flexible display screen due to lateral flipping, which could lead to partial failure of the flexible display screen and the appearance of small black spots, affecting the user experience.

[0028] In one possible implementation, the second component includes a second fixing frame, which is fixedly connected to the second housing. The folding mechanism also includes a first set of connectors, a second set of connectors, and a third set of connectors. One end of the first set of connectors is slidably connected to the first fixing frame, and the other end is rotatably connected to the third set of connectors. One end of the second set of connectors is slidably connected to the second fixing frame, and the other end is rotatably connected to the third set of connectors. The third set of connectors is fixed to the main shaft. The first support plate also includes a second connecting part, which is fixedly connected to the side of the support body facing away from the flexible display screen. The first component also includes a first connecting rod, and the second connecting part is connected to the first arc arm, the main shaft, or the first set of connectors through the first connecting rod.

[0029] In this way, the second connecting part of the first support plate is connected to the first arc arm, the main shaft, or the first set of connecting parts through the first connecting rod. The first support plate, the first connecting rod, the first arc arm, and the first fixed frame can form a four-bar linkage, which is beneficial to improving the motion accuracy of the folding mechanism.

[0030] In one possible implementation, the first link includes a first end and a second end. The first end of the first link is rotatably connected to a first arc arm, a first set of connecting parts, or a main shaft, and the second end of the first link is rotatably connected to a second connecting part of a first support plate.

[0031] It is understood that, in this embodiment, the first support plate can also be connected to the first arc arm via the first connecting rod. In this way, the first support plate, the first connecting rod, the first arc arm, and the first fixing frame can form a four-bar linkage, which is a low-pair structure. This is beneficial for improving the motion accuracy of the first support plate, further reducing the play generated during the movement of the first support plate, and preventing the first support plate from shaking.

[0032] In one possible implementation, the first arc arm further includes an intermediate portion located between the first rotating end and the second rotating end of the first arc arm, and the first end of the first connecting rod is rotatably connected to the intermediate portion of the first arc arm.

[0033] In this way, the first support plate, the first connecting rod, the first arc arm, and the first fixed frame can form a four-bar linkage, which is a low-pair structure. This is beneficial to improving the motion accuracy of the first support plate, further reducing the play generated when the first support plate moves, and preventing the first support plate from shaking.

[0034] In one possible implementation, the first arc arm has a mounting hole that exposes at least a portion of the first connecting rod. This allows the assembly of the first connecting rod, the first arc arm, the first fixing frame, and the first support plate to be performed by observing through the mounting hole in the first arc arm whether the third rotating shaft is correspondingly inserted into the second end of the first connecting rod, thus ensuring assembly accuracy and the normal operation of the folding mechanism.

[0035] In one possible implementation, the first support plate further includes a limiting protrusion, which is fixed to the side of the support body facing away from the flexible display screen. The limiting protrusion is set at an angle to the support body and forms a gap between them. The first set of connectors includes a mating protrusion. In the open state, the limiting protrusion and the mating protrusion are spaced apart, and the mating protrusion is located outside the gap. In the closed state, the mating protrusion is located inside the gap and abuts against the limiting protrusion.

[0036] It is understood that the first support plate in this embodiment may also have a limiting protrusion, and the first set of connecting parts may also have a mating protrusion. When the folding mechanism is in the open state, the limiting protrusion and the mating protrusion may be spaced apart. When the folding mechanism is in the closed state, the mating protrusion may extend into the gap between the limiting protrusion and the support body and abut against the limiting protrusion. In this way, by setting the limiting protrusion and the mating protrusion to cooperate, and setting the limiting protrusion and the mating protrusion to abut against each other when the folding mechanism is in the closed state, the limiting protrusion and the mating protrusion can form an over-constrained fit when the folding mechanism is closed, thus forming an over-constrained fit structure to lock the posture of the first support plate. This can better prevent the first support plate from shaking due to the mechanism's own looseness when the folding mechanism is in the closed state, which would cause the first support plate to collide with the flexible display screen and produce abnormal noise. It can also prevent the flexible display screen from partially failing due to the collision of the first support plate, resulting in small black spots and affecting the user experience.

[0037] Secondly, a folding mechanism is provided. The folding mechanism has an open state and a closed state; the folding mechanism includes a first component, a second component, and a main shaft, the main shaft connecting the first component and the second component. In the open state, the first component and the second component are relatively flattened; in the closed state, the first component and the second component are relatively folded. The first component includes a first support plate, a first fixing frame, and a first arc arm. The first support plate includes a support body and a first connecting part. The support body is located on one side of the first fixing frame, and the first connecting part is fixedly connected to the side of the support body facing the first fixing frame. In the open state, the support body and the first fixing frame are arranged in the thickness direction of the folding mechanism. The first connecting part and the first fixing frame form a solid shaft connection structure. The first arc arm includes a first rotating end and a second rotating end. The first rotating end of the first arc arm forms a solid shaft connection structure with the first fixing frame, and the second rotating end of the first arc arm is rotatably connected to the main shaft.

[0038] It is understood that, in this embodiment, a solid shaft rotational connection structure can be formed between the first support plate and the first fixed frame. Similarly, a solid shaft connection structure can be formed between the first arc arm and the first fixed frame. This reduces, on the one hand, the solid shaft rotational connection between the first support plate and the first fixed frame helps reduce the play generated when the first support plate moves relative to the first fixed frame; on the other hand, the solid shaft connection between the first arc arm and the first fixed frame also helps reduce the play generated when the first arc arm moves relative to the first fixed frame. By reducing the play in the movement of the first support plate and the first arc arm, this embodiment effectively improves the movement accuracy of the first support plate and the folding mechanism. This better prevents the first support plate from wobbling due to play, which could cause it to occupy space in the flexible display screen, leading to a collision between the flexible display screen and the first support plate during a drop, resulting in partial failure of the flexible display screen and small black dots, thus affecting the user experience.

[0039] In one possible implementation, the folding mechanism further includes a first rotating shaft, and the first connecting part of the first support plate and the first rotating end of the first arc arm are both hinged to the first fixed frame through the first rotating shaft.

[0040] In this way, the first support plate and the first arc arm are rotatably connected to the first fixed frame through the same solid axis, which helps to simplify the mechanism and the assembly process.

[0041] In one possible implementation, the first component further includes a second arc arm, which includes a first rotating end and a second rotating end. The first rotating end of the second arc arm is rotatably connected to the first fixed frame, and the second rotating end of the second arc arm is rotatably connected to the main shaft. The first arc arm and the second arc arm are located at both ends of the first fixed frame, and the arrangement direction of the first arc arm and the second arc arm is parallel to the length extension direction of the folding mechanism.

[0042] It is understood that the first component in this embodiment includes a first arc arm and a second arc arm. Both the first and second arc arms can connect to the first fixed frame and the main shaft, and the first and second arc arms can respectively connect to the two ends of the first fixed frame. In this way, when the first fixed frame moves relative to the main shaft, its movement is relatively smooth and will not cause lateral flipping. This effectively avoids the first fixed frame colliding with the flexible display screen due to lateral flipping, which could lead to partial failure of the flexible display screen and the appearance of small black spots, affecting the user experience.

[0043] In one possible implementation, the second component includes a second fixed frame, and the folding mechanism further includes a first set of connectors, a second set of connectors, and a third set of connectors. One end of the first set of connectors is slidably connected to the first fixed frame, and the other end is rotatably connected to the third set of connectors. One end of the second set of connectors is slidably connected to the second fixed frame, and the other end is rotatably connected to the third set of connectors. The third set of connectors is fixed to the main shaft. The first support plate further includes a second connecting part, which is fixedly connected to the side of the support body facing the first fixed frame. The first component also includes a first connecting rod, and the second connecting part is connected to the first arc arm, the main shaft, or the first set of connectors through the first connecting rod.

[0044] In this way, the second connecting part of the first support plate is connected to the first arc arm, the main shaft, or the first set of connecting parts through the first connecting rod. The first support plate, the first connecting rod, the first arc arm, and the first fixed frame can form a four-bar linkage, which is beneficial to improving the motion accuracy of the folding mechanism.

[0045] In one possible implementation, the first link includes a first end and a second end. The first end of the first link is rotatably connected to a first arc arm, a first set of connecting parts, or a main shaft, and the second end of the first link is rotatably connected to a second connecting part of a first support plate.

[0046] It is understood that, in this embodiment, the first support plate can also be connected to the first arc arm via the first connecting rod. In this way, the first support plate, the first connecting rod, the first arc arm, and the first fixing frame can form a four-bar linkage, which is a low-pair structure. This is beneficial for improving the motion accuracy of the first support plate, further reducing the play generated during the movement of the first support plate, and preventing the first support plate from shaking.

[0047] In one possible implementation, the first arc arm further includes an intermediate portion located between the first rotating end and the second rotating end of the first arc arm, and the first end of the first connecting rod is rotatably connected to the intermediate portion of the first arc arm.

[0048] In this way, the first support plate, the first connecting rod, the first arc arm, and the first fixed frame can form a four-bar linkage, which is a low-pair structure. This is beneficial to improving the motion accuracy of the first support plate, further reducing the play generated when the first support plate moves, and preventing the first support plate from shaking.

[0049] In one possible implementation, the first arc arm has a mounting hole that exposes at least a portion of the first connecting rod. This allows the assembly of the first connecting rod, the first arc arm, the first fixing frame, and the first support plate to be performed by observing through the mounting hole in the first arc arm whether the third rotating shaft is correspondingly inserted into the second end of the first connecting rod, thus ensuring assembly accuracy and the normal operation of the folding mechanism.

[0050] In one possible implementation, the first support plate further includes a limiting protrusion, which is fixed to the side of the support body facing the first fixing frame. The limiting protrusion is set at an angle to the support body and forms a gap with the support body. The first set of connecting parts includes a mating protrusion. In the open state, the limiting protrusion and the mating protrusion are spaced apart, and the mating protrusion is located outside the gap. In the closed state, the mating protrusion is located inside the gap and abuts against the limiting protrusion.

[0051] It is understood that the first support plate in this embodiment may also have a limiting protrusion, and the first set of connecting parts may also have a mating protrusion. When the folding mechanism is in the open state, the limiting protrusion and the mating protrusion may be spaced apart. When the folding mechanism is in the closed state, the mating protrusion may extend into the gap between the limiting protrusion and the support body and abut against the limiting protrusion. In this way, by setting the limiting protrusion and the mating protrusion to cooperate, and setting the limiting protrusion and the mating protrusion to abut against each other when the folding mechanism is in the closed state, the limiting protrusion and the mating protrusion can form an over-constrained fit when the folding mechanism is closed, thus forming an over-constrained fit structure to lock the posture of the first support plate. This can better prevent the first support plate from shaking due to the mechanism's own looseness when the folding mechanism is in the closed state, which would cause the first support plate to collide with the flexible display screen and produce abnormal noise. It can also prevent the flexible display screen from partially failing due to the collision of the first support plate, resulting in small black spots and affecting the user experience.

[0052] In one possible implementation, the first component has a first support surface, and the second component has a second support surface; the folding mechanism further includes a support piece, which includes a first fixing part, a connecting part, and a second fixing part connected in sequence. The first fixing part is fixedly connected to the first support surface, and the second fixing part is fixedly connected to the second support surface; in the open state, the first support surface and the second support surface are relatively flattened, and the support piece is relatively flattened; in the closed state, the support piece is bent.

[0053] It is understood that the folding mechanism in this embodiment also includes a support plate. Both ends of the support plate can be fixed ends, with one end used to fix the first support surface of the folding mechanism and the other end used to fix the second support surface of the folding mechanism. Thus, when the folding mechanism is applied to a foldable electronic device, the support plate can be located between the main shaft of the folding mechanism and the flexible display screen. When the electronic device is in the open state, the support plate can effectively cover the folding mechanism, providing a relatively flat support environment for the flexible display screen. When the electronic device switches from the open state to the closed state, the movement of the folding device can drive the two fixed ends of the support plate to move, causing the support plate to deform so that the connecting part of the support plate can be arc-shaped. At this time, the flexible display screen can be folded relative to the support plate under the movement of the folding device. The bent part of the flexible display screen can bend towards the support plate under its own rebound force and fit against the support plate over a large area, so that the shape of the inner bent part of the flexible display screen can be similar to the shape of the connecting part of the support plate, both being arc-shaped.

[0054] In one possible implementation, the surface of the support body of the first support plate facing away from the first fixing frame constitutes the first support surface. In this way, the first support plate can cover the first fixing frame and the first arc arm, while the surface of the first support plate facing the flexible display screen can serve as the first support surface to better support the flexible display screen.

[0055] In one possible implementation, the support piece is a single, integrated structural component. This allows the support piece to better support the flexible display screen and prevent collisions between the flexible display screen and the main shaft of the folding mechanism.

[0056] In one possible implementation, the support sheet is made of stainless steel, fiber cloth, or polycarbonate. This allows the support sheet to be easily bent while maintaining a certain level of structural strength.

[0057] In one possible implementation, the thickness of the support sheet is less than or equal to 0.1 mm. This makes the support sheet thinner and easier to bend.

[0058] Thirdly, a foldable electronic device is provided. The foldable electronic device includes a first housing, a second housing, a flexible display screen, and the aforementioned folding mechanism. A first component of the folding mechanism is connected to the first housing, a second component of the folding mechanism is connected to the second housing, and the flexible display screen is fixedly connected to the first housing and the second housing. In the open state, the first housing and the second housing are relatively flattened, and the flexible display screen is flattened. In the closed state, the first housing and the second housing are relatively folded, and the flexible display screen is bent.

[0059] It is understandable that the electronic device in this embodiment optimizes the folding mechanism so that a solid shaft rotational connection structure can be formed between the first support plate and the first fixed frame, and a solid shaft connection structure can also be formed between the first arc arm and the first fixed frame. This reduces, on the one hand, the solid shaft rotational connection structure between the first support plate and the first fixed frame helps reduce the play generated when the first support plate moves relative to the first fixed frame; on the other hand, the solid shaft connection structure between the first arc arm and the first fixed frame helps reduce the play generated when the first arc arm moves relative to the first fixed frame. By reducing the play during the movement of the first support plate and the first arc arm, this embodiment effectively improves the movement accuracy of the first support plate and the folding mechanism. This better avoids the first support plate wobbling due to play, which could occupy space in the flexible display screen and cause the flexible display screen to collide with the first support plate during a drop, resulting in partial failure of the flexible display screen and small black dots, affecting the user experience.

[0060] In one possible implementation, the first component has a first supporting surface, and the second component has a second supporting surface, both facing the flexible display screen. The flexible display screen includes a first flat portion, a bent portion, and a second flat portion connected in sequence. The first flat portion is fixedly connected to a first housing, and the second flat portion is fixedly connected to a second housing. The electronic device also includes a support plate located between the main shaft and the flexible display screen. The support plate includes a first fixing portion, a connecting portion, and a second fixing portion connected in sequence. The first fixing portion is fixedly connected to the first supporting surface or the first housing, and the second fixing portion is fixedly connected to the second supporting surface or the second housing. In the open state, the support plate is flattened and supports the bent portion of the flexible display screen. In the closed state, the support plate is bent and conforms to the bent portion of the flexible display screen.

[0061] It is understood that in this embodiment, the electronic device is configured such that the flexible display screen is fixed only to the first and second housings, and a support plate is provided between the flexible display screen and the main shaft. Both ends of the support plate can be fixed ends; one end is used to fix the first support surface or the first housing of the folding mechanism, and the other end is used to fix the second support surface or the second housing of the folding mechanism. The support plate is in contact with the flexible display screen. Thus, when the electronic device is in the open state, the support plate can effectively cover the folding mechanism, providing a relatively flat support environment for the flexible display screen. When the electronic device switches from the open state to the closed state, the movement of the folding device can drive the two fixed ends of the support plate to move, causing the support plate to deform so that the connecting part of the support plate can be arc-shaped. At this time, the flexible display screen can be folded relative to the support plate under the movement of the folding device. The bent part of the flexible display screen can bend towards the support plate under its own rebound force and fits the support plate over a large area, so that the shape of the inner bent part of the flexible display screen can be similar to the shape of the connecting part of the support plate, both being arc-shaped.

[0062] In other words, the support plate in this embodiment can not only cover the folding mechanism in the open state, providing a relatively flat support environment for the flexible display screen and ensuring the flatness of the folding mechanism in the unfolded state, but also wrap around and fit the inner bending part of the flexible display screen in the closed state. This allows the inner bending part of the flexible display screen to fit against the support plate over a large area, forming a relatively rounded arc shape. This avoids excessive natural drooping of the flexible display screen when the electronic device is in the closed state, which could cause creases in the flexible display screen due to contact with the main shaft and affect the user experience.

[0063] Secondly, in typical foldable electronic devices, the support plate has one fixed end attached to one of the support plates, while the other end is a free end extending to another support plate. When the electronic device switches from an open to a closed state, the movement of the folding mechanism can move the two support plates, causing the flexible display screen to deform. Under its own rebound force, the flexible display screen bends along the direction of the support plate, causing the support plate to bend to conform to the shape of the flexible display screen. However, the design of one fixed end and the other free end of the support plate makes it prone to fatigue after repeated bending after multiple folds of the electronic device. This causes the free end of the support plate to deviate from its designed movement trajectory, making it more likely to collide with the flexible display screen and produce a scraping sound, affecting the user experience.

[0064] In this embodiment, both ends of the support piece (i.e., the first fixing part and the second fixing part in this embodiment) are fixed ends. Even if the electronic device is folded multiple times, the support piece can still move along the designed motion trajectory under the movement of the first support plate and the second support plate, and fit the flexible display screen. This can effectively avoid the problem of the support piece rubbing against the flexible display screen due to fatigue caused by multiple bending, and effectively improve the user experience.

[0065] In one possible implementation, the support plates are a single, integrated structure. This contrasts with typical electronic devices that use two support plates, each fixed to a support plate on either side of the main shaft. In the open state, the two support plates can be relatively flattened to cover other parts of the folding mechanism and provide a relatively flat support environment for the flexible display. However, in the closed state, the two support plates move away from each other as the support plates on either side of the main shaft move, resulting in them being positioned opposite each other and spaced apart, located on opposite sides of the bent portion of the flexible display. This makes it easy for the bent portion of the flexible display to collide with the main shaft when the electronic device falls in the closed state, potentially causing partial failure of the flexible display and resulting in small black spots, thus affecting the user experience.

[0066] In this embodiment, the support piece is an integral structural component, with both ends serving as fixed ends. One end is used to fix the first support surface or first housing of the folding mechanism, and the other end is used to fix the second support surface or second housing of the folding mechanism. That is, the support piece in this embodiment can extend across the main shaft from one side to the other. Thus, when the electronic device is in a closed state, the support piece can separate the flexible display screen from the main shaft, wrapping and conforming to the flexible display screen. This effectively prevents the flexible display screen from colliding with the main shaft when the electronic device falls in a closed state, extending the lifespan of the flexible display screen and improving the user experience.

[0067] In one possible implementation, the bending portion of the flexible display screen includes a first outer bending portion, a first non-bending portion, an inner bending portion, a second non-bending portion, and a second outer bending portion connected in sequence. The first outer bending portion is connected to a first straight portion, and the second outer bending portion is connected to a second straight portion. In the closed state, the connecting portion of the support sheet is attached to the inner bending portion of the flexible display screen.

[0068] In this way, the support plate can fit and support the inner bend of the flexible display screen better, avoiding collision between the inner bend of the flexible display screen and the main shaft.

[0069] In one possible implementation, the flexible display screen's bending portion includes an inner bending portion, which is disposed opposite to the main shaft; in the closed state, the connecting portion of the support sheet is fitted to the inner bending portion of the flexible display screen.

[0070] In this way, the support plate can fit and support the inner bend of the flexible display screen better, avoiding collision between the inner bend of the flexible display screen and the main shaft.

[0071] In one possible implementation, in the open state, the width of the connecting portion of the support sheet is greater than the width of the inner bend of the flexible display screen.

[0072] It is understandable that, in this embodiment, when the electronic device is in the open state, the width of the connecting portion of the support plate can be greater than the width of the inner bend of the flexible display screen. By setting the width of the connecting portion of the support plate to be greater than the width of the bend of the flexible display screen, the support plate can better fit and support the inner bend of the flexible display screen over a large area. This allows the support plate to not only cover other structures of the folding mechanism in the open state and provide a relatively flat supporting environment for the inner bend of the flexible display screen, ensuring the flatness of the folding mechanism in the unfolded state, but also to better wrap and fit the inner bend of the flexible display screen in the closed state. This allows the inner bend of the flexible display screen to present a more rounded arc shape under the action of the support plate, thereby preventing the inner bend of the flexible display screen from drooping excessively when the electronic device is closed, thus avoiding creases caused by contact with the main shaft or partial failure of the inner bend due to collision with the main shaft, resulting in small black spots and affecting the user experience.

[0145] The embodiments of this application are described below with reference to the accompanying drawings.

[0146] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. The directional terms mentioned in the embodiments of this application, such as "upper," "lower," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. "Multiple" refers to at least two.

[0147] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0148] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0149] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in another embodiment" appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0150] It is understood that the specific embodiments described herein are merely for explaining the relevant application and not for limiting the application. It should also be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings.

[0151] Figure 1 This is a schematic diagram of the electronic device 100 provided in the embodiments of this application when it is in the open state. Figure 2 yes Figure 1 The diagram shows the structure of the electronic device 100 in the closed state. Figure 3a yes Figure 1 The diagram shows a cross-sectional view of one embodiment of the electronic device 100 cut along point AA. Figure 3b yes Figure 2 The diagram shows a cross-sectional view of one embodiment of the electronic device 100 cut along BB.

[0152] like Figures 1 to 3b As shown, the electronic device 100 includes a folding device 10 and a flexible display screen 20, the flexible display screen 20 being mounted on the folding device 10. The folding device 10 has an open state and a closed state, and can switch between the open and closed states. The flexible display screen 20 moves with the folding device 10. When the folding device 10 is in the open state, the flexible display screen 20 is in an open state, and the electronic device 100 is also in the open state (please refer to...). Figure 1 and Figure 3a (As shown); When the folding device 10 is in the closed state, the flexible display screen 20 is in a closed state, and the electronic device 100 is also in a closed state (please refer to...). Figure 2 and Figure 3b (As shown).

[0153] Figure 4a yes Figure 3a A simplified schematic diagram of part of the structure of the electronic device 100 shown. Figure 4b yes Figure 3b A simplified schematic diagram of part of the structure of the electronic device 100 shown. Figure 5 yes Figure 1 The diagram shows the structure of the folding device 10 of the electronic device 100 in some embodiments. Figure 6 yes Figure 5 The diagram shown is a partially exploded view of the folding device 10 in some embodiments. It should be noted that... Figure 4a and Figure 4bThe electronic device 100 shown only illustrates the partial structure of the first housing 1 near the folding mechanism 3, the partial structure of the second housing 2 near the folding mechanism 3, the partial structure of the flexible display screen 20, the support plate 4, and the partial structure of the folding mechanism 3. For the sake of simplicity, the folding mechanism 3 only shows the structure of the main shaft 31, the first support plate 332 of the first component 33, and the second support plate 342 of the second component 34, concealing the other structures of the first component 33 (excluding the first support plate 332) and the other structures of the second component 34 (excluding the second support plate 342).

[0154] like Figures 4a to 6 As shown, the folding device 10 may include a first housing 1, a second housing 2, and a folding mechanism 3. The folding mechanism 3 is connected between the first housing 1 and the second housing 2. That is, the folding mechanism 3 is located between the first housing 1 and the second housing 2, with one side of the folding mechanism 3 connected to the first housing 1 and the other side connected to the second housing 2. Through the movement of the folding mechanism 3, the first housing 1 and the second housing 2 can be relatively unfolded to an open state or relatively folded to a closed state.

[0155] Exemplarily, the folding mechanism 3 may include a main shaft 31 and a connecting assembly 32. The connecting assembly 32 connects the main shaft 31 to the first housing 1 and also connects the main shaft 31 to the second housing 2. The connecting assembly 32 can move (e.g., including rotation and linear sliding) so that the first housing 1 and the second housing 2 can move relative to the main shaft 31 to achieve relative unfolding or relative folding of the first housing 1 and the second housing 2. The connecting assembly 32 may include a first assembly 33 and a second assembly 34. The first assembly 33 may connect a third assembly 35 to the first housing 1. The second assembly 34 may connect the third assembly 35 to the second housing 2. The first assembly 33 and the second assembly 34 may be symmetrical structures. The first assembly 33 may have a first support surface 32a. The second assembly 34 may have a second support surface 32b. Both the first support surface 32a and the second support surface 32b can be used to support the flexible display screen 20.

[0156] For example, the first component 33 may include a first support plate 332. The surface of the first support plate 332 facing the flexible display screen 20 may form a first support surface 32a. The second component 34 may include a second support plate 342. The surface of the second support plate 342 facing the flexible display screen 20 may form a second support surface 32b.

[0157] Combination Figure 3aAs shown, when the folding device 10 is in the open state, the first housing 1 and the second housing 2 are unfolded relative to each other, and the folding mechanism 3 is also in the open state. The first support plate 332 can be flattened relative to the second support plate 342. At this time, the first support surface 32a can be flattened relative to the second support surface 32b. In the open state, the angle between the first housing 1 and the second housing 2 can be approximately 180° (a slight deviation is also allowed, such as 165°, 177°, or 185°). In this state, the electronic device 100 has a larger width and a larger planar size, resulting in a better user experience.

[0158] Combination Figure 3b As shown, when the folding device 10 is in the closed state, the first housing 1 and the second housing 2 are folded relative to each other, and the folding mechanism 3 is also in the closed state. In the closed state, the first housing 1 and the second housing 2 can be completely closed to be parallel to each other (a slight deviation is allowed), with a gap between them. At this time, the electronic device 100 has a smaller width, making it easier for the user to store and hold. The first support plate 332 can be folded relative to the second support plate 342. The first support surface 32a can be folded relative to the second support surface 32b.

[0159] Furthermore, the folding device 10, the folding mechanism 3, and the electronic device 100 can also be in an intermediate state between an open state and a closed state (not shown in the figure). In this state, the angle between the first housing 1 and the second housing 2 can be greater than the angle between them when they are in the closed state and less than the angle between them when they are in the open state. Therefore, the electronic device 100 can switch between the open state, the intermediate state, and the closed state through the movement of the folding mechanism 3.

[0160] For example, the folding mechanism 3 may also include a support sheet 4. The support sheet 4 may be generally rectangular in shape. The support sheet 4 may be made of materials such as stainless steel, fiber cloth, or polycarbonate (PC). The thickness of the support sheet 4 may be less than the thickness of the flexible display screen 20.

[0161] For example, the thickness of the support sheet 4 can be less than or equal to 0.1 mm. This makes the support sheet 4 thinner and easier to bend. In some embodiments, the thickness of the support sheet 4 can be between 0.03 mm and 0.08 mm. This provides a moderate thickness, allowing the support sheet 4 to be easily bent while maintaining good rigidity, thus effectively supporting the flexible display screen 20.

[0162] For example, the support piece 4 can be an integral structural component. It should be noted that the support piece 4 being an integral structural component means that the support piece 4 is a single structural component. It can be that the support piece 4 is a single structural component formed in one piece, or it can be that the support piece 4 includes multiple layers of structures stacked together to form a single structural component formed in one piece.

[0163] For example, the support piece 4 may include a first fixing part 41, a connecting part 42, and a second fixing part 43 connected in sequence. The first fixing part 41 may be fixed to the first support plate 332 of the first housing 1 or the folding mechanism 3. The second fixing part 43 may be fixed to the second support plate 342 of the second housing 2 or the folding mechanism 3. That is, both ends of the support piece 4 (i.e., the first fixing part 41 and the second fixing part 43 in this embodiment) can be fixed ends for fixing and connecting other structural components of the folding device 10. The connecting part 42 of the support piece 4 may deform. In this embodiment, both the first fixing part 41 and the second fixing part 43 of the support piece may be fixed to the folding mechanism 3.

[0164] Exemplarily, the folding mechanism 3 may also have an adhesive layer 44. The support piece 4 can be bonded and fixed to the first support plate 332 and the second support plate 342 via the adhesive layer 44. In some embodiments, the first support plate 332 may have an adhesive groove 32c. The opening of the adhesive groove 32c may be formed on the first support surface 32a of the first support plate 332. The adhesive layer 44 may be disposed within the adhesive groove 32c. In this way, the adhesive layer 44 can be set using the thickness dimension of the first support plate 332, making the structure of the folding device 10 more compact. In some embodiments, the first fixing portion 41 and / or the second fixing portion 43 of the support piece 4 may also extend relative to the folding mechanism 3 in a direction away from the connecting portion 42. For example, the first fixing portion 41 of the support piece 4 may extend relative to the first support plate 332 in a direction away from the connecting portion 42 and overlap the first housing 1. Alternatively, the first fixing portion 41 of the support piece 4 may also extend relative to the first support plate 332 in a direction away from the connecting portion 42 and be spaced apart from the first housing 1. At this time, there may be no contact between the support plate 4 and the first housing 1.

[0165] For example, the support piece 4 can be located between the flexible display screen 20 and the main shaft 31 of the folding mechanism 3. When the electronic device 100 is in the open state, the support piece 4 can be relatively flattened. The support piece 4 can be located between the folding mechanism 3 and the flexible display screen 20. The connecting portion 42 of the support piece 4 can be positioned directly opposite the main shaft 31 of the folding mechanism 3. The support piece 4 can cover the folding mechanism 3 and provide a flat supporting environment for the flexible display screen 20. When the electronic device 100 is in the closed state, the support piece 4 can be relatively folded. The connecting portion 42 of the support piece 4 can deform. The support piece 4 can be located between the folding mechanism 3 and the flexible display screen 20. The connecting portion 42 of the support piece 4 can be located between the flexible display screen 20 and the main shaft 31. The support piece 4 can be approximately teardrop-shaped.

[0166] Please refer to it again. Figure 1 , Figure 3a as well as Figure 3b The flexible display screen 20 can integrate display and touch sensing functions. The display function of the flexible display screen 20 is used to display images, videos, etc., while the touch sensing function is used to sense user touch actions to achieve human-computer interaction. For example, the flexible display screen 20 can be an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MLED) display, a microorganic light-emitting diode (MALED) display, a micro organic light-emitting diode (MOLED) display, a quantum dot light-emitting diode (QLED) display, etc.

[0167] For example, the flexible display screen 20 may include a first straight portion 201, a bent portion 202, and a second straight portion 203 connected in sequence. The first straight portion 201 of the flexible display screen 20 is fixedly connected to the first housing 1, and the second straight portion 203 of the flexible display screen 20 is fixedly connected to the second housing 2. At this time, the bent portion 202 of the flexible display screen 20 at least partially corresponds to the folding mechanism 3. During the relative movement between the first housing 1 and the second housing 2, the first straight portion 201 of the flexible display screen 20 moves with the first housing 1, the second straight portion 203 of the flexible display screen 20 moves with the second housing 2, and the bent portion 202 of the flexible display screen 20 deforms. The bent portion 202 of the flexible display screen 20 may include a first outer bent portion 2021, a first non-bent portion 2022, an inner bent portion 2023, a second non-bent portion 2024, and a second outer bent portion 2025 connected in sequence. The first outer bent portion 2021 may be connected to the first straight portion 201. The second outer bend 2025 can be connected to the second straight section 203. The inner bend 2023 can be correspondingly arranged with the main shaft 31 of the folding mechanism 3. It should be noted that... Figure 3a and Figure 3b The flexible display screen 20 is schematically divided into a first straight portion 201, a bent portion 202, and a second straight portion 203 by relatively wide dashed lines, and the bent portion 202 is schematically divided into a first outer bent portion 2021, a first non-bent portion 2022, an inner bent portion 2023, a second non-bent portion 2024, and a second outer bent portion 2025 by relatively narrow dashed lines.

[0168] Among them, such as Figure 3a As shown, when the folding device 10 is in the open state, the flexible display screen 20 is flattened and in an open shape. At this time, the first flat portion 201, the bent portion 202, and the second flat portion 203 of the flexible display screen 20 can be coplanar, allowing the flexible display screen 20 to have a planar or near-planar shape, resulting in a larger display area and a better user experience. The first support plate 332 and the second support plate 342 of the folding mechanism 3 can be relatively flattened. The first support surface 32a of the first support plate 332 and the second support surface 32b of the second support plate 342 can be used together to support the bent portion 202 of the flexible display screen 20. The projection of the inner bent portion 2023 of the flexible display screen 20 onto the main shaft 31 along the thickness direction of the electronic device 100 can cover at least a portion of the main shaft 31.

[0169] Among them, such as Figure 3bAs shown, when the folding device 10 is in the closed state, the flexible display screen 20 is located inside the first housing 1, the folding mechanism 3, and the second housing 2. The bent portion 202 of the flexible display screen 20 can deform under the support of the first support plate 332 and the second support plate 342. The second straight portion 203 is opposite to and parallel to the first straight portion 201, and the flexible display screen 20 is in a closed state. The bent portion 202 can be approximately teardrop-shaped. The first support plate 332 and the second support plate 342 can be folded relative to each other at an angle. The first support surface 32a of the first support plate 332 and the second support surface 32b of the second support plate 342 can be at an angle. The first support surface 32a of the first support plate 332 can be used to support the first non-bent portion 2022 of the flexible display screen 20. The second support surface 32b of the second support plate 342 can be used to support the second non-bent portion 2024 of the flexible display screen 20. The inner bending portion 2023 of the flexible display screen 20 can be positioned closer to the main shaft 31 than other parts of the flexible display screen 20.

[0170] Understandably, when the folding device 10 is in the intermediate state, the flexible display screen 20 is in an intermediate state between the open and closed states.

[0171] In this embodiment, the flexible display screen 20 can move with the folding device 10. When the electronic device 100 is in the open state, the flexible display screen 20 is flattened, enabling full-screen display and giving the electronic device 100 a larger display area to improve the user's viewing experience. When the electronic device 100 is in the closed state, its planar dimensions are small, making it easy for users to carry and store.

[0172] In some embodiments, the bending portion 202 of the flexible display screen 20 may not include the first outer bending portion 2021 and the second outer bending portion 2025. In this case, the first non-bending portion 2022 of the bending portion 202 of the flexible display screen 20 can be connected to the first straight portion 201, and the second non-bending portion 2024 can be connected to the second straight portion 203. In the closed state, the flexible display screen 20 can be approximately ball-and-stick shaped.

[0173] In some embodiments, the electronic device 100 may further include multiple modules (not shown in the figure), which can be housed inside the folding device 10. The multiple modules of the electronic device 100 may include, but are not limited to, a motherboard, processor, memory, battery, camera module, earpiece module, speaker module, microphone module, antenna module, sensor module, etc. The embodiments of this application do not specifically limit the number, type, or location of the modules of the electronic device 100.

[0174] In this embodiment, the electronic device 100 has two perpendicular length directions, width directions, and thickness directions. This embodiment is described using the example where the rotation axis of the electronic device 100 is parallel to its length direction. In this case, the electronic device 100 can rotate left and right, and its folding and unfolding affects its width. The thickness direction of the electronic device 100 is perpendicular to the flexible display screen 20. In other embodiments, the rotation axis of the electronic device 100 may also be parallel to its width direction. In this case, the electronic device 100 can rotate up and down, and its folding and unfolding affects its length.

[0175] Please combine again Figures 3a to 5 As shown, when the electronic device 100 is in the open state, the support piece 4 can be relatively flattened. The support piece 4 can fit against the bent portion 202 of the flexible display screen 20. The width H1 of the connecting portion 42 of the support piece 4 can be smaller than the width H2 of the bent portion 202 of the flexible display screen 20. The width H1 of the connecting portion 42 of the support piece 4 can also be larger than the width H3 of the inner bent portion 2023 of the bent portion 202 of the flexible display screen 20.

[0176] When the electronic device 100 is in the closed state, the support piece 4 can be folded relative to it. The connecting portion 42 of the support piece 4 can conform to the inner bending portion 2023 of the flexible display screen 20. The shape of the connecting portion 42 of the support piece 4 can be similar to the shape of the inner bending portion 2023 of the flexible display screen 20. For example, the connecting portion 42 of the support piece 4 can be parallel to the inner bending portion 2023 of the flexible display screen 20.

[0177] During the transition of the electronic device 100 from an open to a closed state, the first housing 1 and the second housing 2 can be folded relative to each other, and the folding mechanism 3 can also be folded relative to each other. At this time, the support piece 4 can deform under the action of the folding mechanism 3, and the connecting portion 42 of the support piece 4 can gradually bend. The flexible display screen 20 can deform under the action of the first housing 1 and the second housing 2, and the inner bending portion 2023 of the flexible display screen 20 can always be in contact with the support piece 4, gradually bending along with the support piece 4. Specifically, the connecting portion 42 of the support piece 4 can gradually bend into an arc shape, and the inner bending portion 2023 of the flexible display screen 20 can gradually bend into an arc shape along with the support piece 4. The contact between the support piece 4 and the flexible display screen 20 can be complete, partial (e.g., at least a portion of the inner bending portion 2023 of the flexible display screen 20 is in contact with the support piece 4), or a line contact between the support piece 4 and the end of the flexible display screen 20 facing the main shaft 31.

[0178] It is understood that in this embodiment, the electronic device 100 is configured such that the flexible display screen 20 is fixed only to the first housing 1 and the second housing 2, and a support plate 4 is provided between the flexible display screen 20 and the main shaft 31. Both ends of the support plate 4 can be fixed ends, used to fix and connect the first support plate 332 and the second support plate 342 of the folding mechanism 3. The portion located between the two fixed ends is not fixed to other structural components, and the support plate 4 is in contact with the flexible display screen 20. Thus, when the electronic device 100 is in the open state, the support plate 4 can effectively cover the folding mechanism 3, providing a relatively flat support environment for the flexible display screen 20. When the electronic device 100 switches from the open state to the closed state, the movement of the folding device 10 can drive the two support plates (i.e., the first support plate 332 and the second support plate 342 in this embodiment) to move, that is, drive the two fixed ends of the support plate 4 to move, causing the support plate 4 to deform so that the portion of the support plate 4 located between the two fixed ends (i.e., the connecting portion 42 in this embodiment) can be arc-shaped. At this time, the flexible display screen 20 can be folded relative to each other under the movement of the folding device 10. The bent part 202 of the flexible display screen 20 can be bent in the direction toward the support piece 4 under its own rebound force and fit the support piece 4 in a large area, so that the shape of the inner bent part 2023 of the flexible display screen 20 can be similar to the shape of the connecting part 42 of the support piece 4, both being arc-shaped.

[0179] In other words, the support plate 4 in this embodiment can not only cover the folding mechanism 3 in the open state, providing a relatively flat support environment for the flexible display screen 20 and ensuring the flatness of the folding mechanism 3 in the flattened state, but also wrap and fit the inner bending part 2023 of the flexible display screen in the closed state. This allows the inner bending part 2023 of the flexible display screen 20 to fit with the support plate 4 over a large area, forming a relatively rounded arc shape. This avoids the flexible display screen 20 from drooping too much when the electronic device 100 is in the closed state, causing it to contact the main shaft 31 and resulting in creases in the flexible display screen 20, which would affect the user experience.

[0180] Secondly, in typical foldable electronic devices, the support plate has one fixed end attached to one of the support plates, while the other end is a free end extending to another support plate. When the electronic device switches from an open to a closed state, the movement of the folding mechanism can move the two support plates, causing the flexible display screen to deform. Under its own rebound force, the flexible display screen bends along the direction of the support plate, causing the support plate to bend to conform to the shape of the flexible display screen. However, the design of one fixed end and the other free end of the support plate makes it prone to fatigue after repeated bending after multiple folds of the electronic device. This causes the free end of the support plate to deviate from its designed movement trajectory, making it more likely to collide with the flexible display screen and produce a scraping sound, affecting the user experience.

[0181] In this embodiment, the support piece 4 is an integral structural component. Its two ends (i.e., the first fixing part 41 and the second fixing part 43 in this embodiment) are fixed to the first support plate 332 and the second support plate 342 respectively. Even if the electronic device is folded multiple times, the support piece 4 can still move along the designed motion trajectory under the movement of the first support plate 332 and the second support plate 342, and fit the flexible display screen. This can effectively avoid the problem of the support piece 4 rubbing against the flexible display screen 20 due to fatigue caused by multiple bending, and effectively improve the user experience.

[0182] Furthermore, unlike typical electronic devices which include two support plates fixed to support plates on either side of the main shaft, this device features two support plates that, when open, can be relatively flattened to cover other parts of the folding mechanism and provide a relatively flat support environment for the flexible display. However, when closed, the two support plates move away from each other as the support plates on either side of the main shaft move. These two support plates are positioned opposite each other and spaced apart, located on opposite sides of the bent portion of the flexible display. This makes it easy for the bent portion of the flexible display to collide with the main shaft when the electronic device falls while closed, potentially causing partial failure of the flexible display and resulting in small black spots, thus affecting the user experience.

[0183] In this embodiment, the support piece 4 is an integral structural component, and both ends of the support piece 4 can be fixed ends. One end is used to fix the first support surface 32a or the first housing 1 of the folding mechanism 3, and the other end is used to fix the second support surface 32b or the second housing 2 of the folding mechanism 3. That is, in this embodiment, the support piece 4 can extend from one side of the main shaft 31 across the main shaft 31 to the other side of the main shaft 31. In this way, when the electronic device 100 is in the closed state, the support piece 4 can separate the flexible display screen 20 from the main shaft 31, wrap around and fit the flexible display screen 20, thereby effectively preventing the flexible display screen 20 from colliding with the main shaft 31 when the electronic device 100 falls in the closed state, which helps to extend the service life of the flexible display screen 20 and improve the user experience.

[0184] Furthermore, in this embodiment, when the electronic device 100 is in the open state, the width H1 of the connecting portion 42 of the support piece 4 can be greater than the width H3 of the inner bending portion 2023 of the flexible display screen 20. Thus, by setting the width H1 of the connecting portion 42 of the support piece 4 to be greater than the width H3 of the inner bending portion 2023 of the flexible display screen 20, the area where the support piece 4 can freely bend is wider, thereby allowing for better large-area contact and support of the inner bending portion 2023 of the flexible display screen 20. This enables the support piece 4 to not only cover other structures of the folding mechanism 3 in the open state but also provide a relatively flat supporting environment for the inner bending portion 2023 of the flexible display screen 20, ensuring the flatness of the folding mechanism 3 in the unfolded state. The inner bend 2023 of the flexible display screen 20 can be well wrapped and fitted in the closed state, so that the inner bend 2023 of the flexible display screen 20 can present a relatively rounded arc shape under the action of the support piece 4. This can avoid the large amount of natural droop of the inner bend 2023 of the flexible display screen 20 when the electronic device 100 is closed, which would cause the flexible display screen 20 to crease due to contact with the main shaft 31 or cause the inner bend 2023 to partially fail and produce small black spots due to collision with the main shaft 31, thus affecting the user experience.

[0185] In some embodiments, the electronic device 100 may further include a bamboo book layer (not shown). The bamboo book layer may be fixed to the non-display side of the flexible display screen 20. The bamboo book layer may be located between the support sheet 4 and the flexible display screen 20.

[0186] In some embodiments, the support piece 4 may also have multiple through holes arranged in an array. The through holes can be used to reduce the stress when the support piece 4 is bent, making the support piece 4 easier to bend.

[0187] The following section will describe the structure of the folding mechanism 3 in conjunction with the accompanying drawings.

[0188] Figure 7 yes Figure 6 The diagram shows an exploded view of the folding mechanism 3 in one embodiment.

[0189] like Figure 7 As shown, the folding mechanism 3 can have two connecting components 32. The two connecting components 32 can be connected to both ends of the main shaft 31, respectively. The two connecting components 32 can have identical, symmetrical, or similar structures. In other embodiments, the number of connecting components 32 can be one, or three or more; this application does not strictly limit this.

[0190] It should be noted that, for ease of description, the following text will take one of the connecting components 32 and its cooperation with the spindle 31 as an example, and the specific design of other connecting components 32 will not be described in detail.

[0191] Figure 8 yes Figure 7 The diagram shows an exploded view of the connecting component 32 of the folding mechanism 3 in some embodiments. Figure 9 yes Figure 8 The diagram shown is a structural schematic from another perspective.

[0192] like Figures 7 to 9 As shown, the connecting component 32 of the folding mechanism 3 may further include a third component 35. A first component 33 can connect the third component 35 to the first housing 1. A second component 34 can connect the third component 35 to the second housing 2. The first component 33 may include a first fixing frame 331, a first support plate 332, a first arc arm 333, a second arc arm 334, a first connecting rod 335, a second connecting rod 336, and multiple rotating shafts 337. The second component 34 may include a second fixing frame 341, a second support plate 342, a third arc arm 343, a fourth arc arm 344, a third connecting rod 345, a fourth connecting rod 346, and multiple rotating shafts 347.

[0193] It should be noted that, for the sake of simplicity, the following text will take the first component 33 and its cooperation with the third component 35 as an example, and the specific design of the second component 34 will not be described in detail.

[0194] Figure 10 yes Figure 8 The diagram shows a partial structure of the first component 33 in some embodiments. Figure 11 yes Figure 8 The diagram shows a partial structure of the first component 33 in some embodiments, representing an assembly structure.

[0195] like Figure 10 and Figure 11 As shown, the first arc arm 333 may include a first rotating end 333a, a second rotating end 333b, and an intermediate portion 333c located between the first rotating end 333a and the second rotating end 333b. The first connecting rod 335 may include a first end 335a and a second end 335b.

[0196] For example, the first rotating end 333a of the first arc arm 333 may have a first hole 3331. The middle portion 333c of the first arc arm 333 may have a second hole 3332. The first hole 3331 and the second hole 3332 of the first arc arm 333 may be arranged parallel to each other. The middle portion 333c of the first arc arm 333 may have two spaced connecting protrusions 3333. The two connecting protrusions 3333 of the first arc arm 333 may each have a small hole, and the two small holes may be coaxially arranged and together form the second hole 3332 of the first arc arm 333. The second rotating end 333b of the first arc arm 333 may have an arc-shaped protrusion 3334. The number of arc-shaped protrusions 3334 of the first arc arm 333 may be two. The two arc-shaped protrusions 3334 of the first arc arm 333 may be provided on opposite sides of the first arc arm 333 along the rotation axis of the electronic device 100. The line connecting the curvature centers of the two arc-shaped protrusions 3334 can be parallel to the axial direction of the first hole 3331 of the first arc arm 333.

[0197] For example, the first end 335a of the first link 335 may have a first connecting hole 3351, and the second end 335b may have a second connecting hole 3352. The first connecting hole 3351 and the second connecting hole 3352 of the first link 335 may be arranged in parallel.

[0198] For example, the first end 335a of the first link 335 may be located between the two connecting protrusions 3333 of the middle portion 333c of the first arc arm 333. The first connecting hole 3351 of the first end 335a of the first link 335 may be coaxially arranged with the second hole 3332 of the middle portion 333c of the first arc arm 333. The second end 335b of the first link 335 may be located on one side of the first arc arm 333.

[0199] For example, the plurality of rotating shafts 337 of the first component 33 may include a first rotating shaft 3371, a second rotating shaft 3372, and a third rotating shaft 3373. The number of each of the first rotating shaft 3371, second rotating shaft 3372, and third rotating shaft 3373 may be two. One of the first rotating shafts 3371 may pass through the first hole 3331 of the first rotating end 333a of the first arc arm 333. One of the second rotating shafts 3372 may pass through the second hole 3332 of the middle portion 333c of the first arc arm 333 and the first connecting hole 3351 of the first end 335a of the first connecting rod 335; that is, the middle portion 333c of the first arc arm 333 can be rotatably connected to the first end 335a of the first connecting rod 335 via one of the second rotating shafts 3372. One of the third rotating shafts 3373 may pass through the second connecting hole 3352 of the second end 335b of the first connecting rod 335.

[0200] Figure 12 yes Figure 8 The first mounting bracket 331 of the first component 33 shown is a structural schematic diagram in some embodiments. Figure 13 yes Figure 12 The diagram shows the structure of the first fixing frame 331 from another perspective. It should be noted that... Figure 13 The perspective of the structure shown is Figure 12 The structure shown is viewed from the perspective of being flipped up and down.

[0201] like Figure 12 and Figure 13 As shown, the first fixing frame 331 may have a first rotating body 331a and a second rotating body 331b. The number of the first rotating body 331a and the second rotating body 331b of the first fixing frame 331 may both be two, and the two first rotating bodies 331a and the two second rotating bodies 331b may be distributed at both ends of the first fixing frame 331 along the rotation axis of the electronic device 100 (which is also the length extension direction of the first fixing frame 331 in this embodiment).

[0202] For example, the first rotating body 331a of the first fixing frame 331 may include a first rotating hole 3311. The two first rotating holes 3311 of the first fixing frame 331 may be distributed at both ends of the first fixing frame 331 and coaxially arranged. The second rotating body 331b of the first fixing frame 331 may include a second rotating hole 3312. The two second rotating holes 3312 of the first fixing frame 331 may be distributed at both ends of the first fixing frame 331 and coaxially arranged. The first rotating holes 3311 and second rotating holes 3312 of the first fixing frame 331 may be arranged parallel to each other.

[0203] Figure 14 yes Figure 8 The diagram shows a partial structure of the first component 33 in some embodiments, representing an assembly structure. Figure 15 yes Figure 14 The diagram shown is a structural schematic from another perspective.

[0204] like Figures 12 to 15As shown, the first arc arm 333 and the second arc arm 334 can be located at both ends of the first fixed frame 331, and both are rotatably connected to the first fixed frame 331. The first rotating end 333a of the first arc arm 333 can be rotatably connected to one of the second rotating bodies 331b of the first fixed frame 331. The first rotating shaft 3371, which passes through the first hole 3331 of the first rotating end 333a of the first arc arm 333, can also pass through the second rotating hole 3312 of one of the second rotating bodies 331b of the first fixed frame 331. That is, the first rotating end 333a of the first arc arm 333 can be rotatably connected to one of the second rotating bodies 331b of the first fixed frame 331 via the first rotating shaft 3371. The first rotating end 333a of the first arc arm 333 can be hinged to one of the second rotating bodies 331b of the first fixed frame 331. In this case, the first arc arm 333 can rotate relative to the first fixed frame 331 around a first rotation center. The first rotation center can be the axis of the first rotating shaft 3371. The second rotating end 333b of the first arc arm 333 can be located on one side of the first fixed frame 331.

[0205] It should be understood that the structure of the second arc arm 334, the structure of the second connecting rod 336, and the connection relationship between the second arc arm 334 and the second connecting rod 336 can all be referenced to the structure of the first arc arm 333, the structure of the first connecting rod 335, and the connection relationship between the first arc arm 333 and the first connecting rod 335; identical parts will not be repeated. The second arc arm 334 may include a first rotating end 334a, a second rotating end 334b, and an intermediate portion 334c located between the first rotating end 334a and the second rotating end 334b. The second connecting rod 336 may include a first end 336a and a second end 336b. Another first rotating shaft 3371 may pass through the first rotating end 334a of the second arc arm 334. The intermediate portion 334c of the second arc arm 334 can be rotatably connected to the first end 336a of the second connecting rod 336 via another second rotating shaft 3372. Another third rotating shaft 3373 may pass through the second end 336b of the second connecting rod 336.

[0206] The first rotating end 334a of the second arc arm 334 can be rotatably connected to another second rotating body 331b of the first fixed frame 331. The pivot 337 passing through the first rotating end 334a of the second arc arm 334 can also pass through the other second rotating body 331b of the first fixed frame 331. That is, the first rotating end 334a of the second arc arm 334 can be rotatably connected to the other second rotating body 331b of the first fixed frame 331 via the pivot 337. The first rotating end 334a of the second arc arm 334 can be hinged to the other second rotating body 331b of the first fixed frame 331. In this case, the second arc arm 334 can also rotate relative to the first fixed frame 331 around a first rotation center. The first arc arm 333 and the second arc arm 334 can be installed at both ends of the first fixed frame 331. The second rotating end 334b ​​of the second arc arm 334 can be located on the same side of the first fixed frame 331 as the second rotating end 333b of the first arc arm 333, for example, it can be located on the side of the second rotating body 331b of the first fixed frame 331 that is opposite to the first rotating body 331a.

[0207] Figure 16 yes Figure 8 The diagram shows the structure of the first support plate 332 in some embodiments. Figure 17 yes Figure 16 The diagram shows the structure of the first support plate 332 from another perspective. It should be noted that... Figure 17 The perspective of the structure shown is Figure 16 The structure shown is viewed from the perspective of being flipped up and down.

[0208] like Figure 16 and Figure 17 As shown, the first support plate 332 may include a support body 3321, a first connecting portion 3322, and a second connecting portion 3323. The support body 3321 may include a first surface 332a and a second surface 332b disposed opposite to each other. The first connecting portion 3322 and the second connecting portion 3323 of the first support plate 332 may both be located on the side of the second surface 332b of the support body 3321 facing away from the first surface 332a, and both are fixedly connected to the support body 3321. The number of the first connecting portion 3322 and the second connecting portion 3323 may both be two. Both the two first connecting portions 3322 and the two second connecting portions 3323 may be located at both ends of the first support plate 332.

[0209] For example, the first connecting portion 3322 may include a first protrusion 3327. Two first protrusions 3327 may be arranged at intervals along the length extension direction of the first support plate 332. Each first protrusion 3327 may have a first hole 3327a. The two first holes 3327a of the first connecting portion 3322 may be coaxially arranged.

[0210] For example, the second connecting portion 3323 may include two second protrusions 3328. The two second protrusions 3328 may be arranged at intervals along the length extension direction of the first support plate 332. Each second protrusion 3328 may have a second hole 3328a. The two second holes 3328a may be coaxially arranged. The second holes 3328a of the second connecting portion 3323 may be spaced apart from and parallel to the first hole 3327a of the first connecting portion 3322.

[0213] like Figures 17 to 21 As shown, the support body 3321 of the first support plate 332 can be located on one side of the first fixed frame 331. The first connecting part 3322 of the first support plate 332 can be rotatably connected to the first rotating body 331a of the first fixed frame 331 (please refer to the reference). Figure 20 One of the second connecting parts 3323 of the first support plate 332 is rotatably connected to the second end 335b of the first connecting rod 335, and the other second connecting part 3323 is rotatably connected to the second end 336b of the second connecting rod 336 (please refer to the reference). Figure 21 ).

[0214] For example, taking the first connecting portion 3322 of one set of first support plates 332 and the first rotating body 331a of the first fixing frame 331 as an example, the two first protrusions 3327 of the first connecting portion 3322 of the first support plate 332 can be located on opposite sides of the first rotating hole 3311 of the first rotating body 331a of the first fixing frame 331. The first hole 3327a of the first protrusion 3327 of the first support plate 332 can be coaxially arranged with the first rotating hole 3311 of the first fixing frame 331. The plurality of rotating shafts 337 of the first assembly 33 can also include a first rotating shaft 3374. The number of first rotating shafts 3374 can be two. One of the first rotating shafts 3374 can pass through the first hole 3327a of the first support plate 332 and the first rotating hole 3311 of the first fixing frame 331. That is, the first connecting portion 3322 of the first support plate 332 can be rotatably connected to the first rotating body 331a of the first fixing frame 331 through the first rotating shaft 3374. The first connecting portion 3322 of the first support plate 332 is hinged to the first rotating body 331a of the first fixed frame 331. The rotation center of the first support plate 332 relative to the first fixed frame 331 can be the axis of the first rotating shaft 3374. The rotation center of the first support plate 332 relative to the first fixed frame 331 can be spaced apart from and parallel to the rotation center of the first arc arm 333 relative to the first fixed frame 331 (which in this embodiment is also the axis of the first rotating shaft 3374).

[0215] For example, taking one of the second connecting portions 3323 of the first support plate 332 and the second end 335b of the first connecting rod 335 as an example, the two second protrusions 3328 of the second connecting portion 3323 of the first support plate 332 can be located on opposite sides of the second end 335b of the first connecting rod 335. The second hole 3328a of the second protrusion 3328 of the first support plate 332 can be connected to the second connecting hole 3352 of the second end 335b of the first connecting rod 335 (please refer to...). Figure 10 (As shown) Coaxial arrangement. The third rotating shaft 3373, which passes through the second connecting hole 3352 of the first connecting rod 335, can also pass through the second hole 3328a of the first support plate 332. That is, the second connecting part 3323 of the first support plate 332 can be rotatably connected to the second end 335b of the first connecting rod 335 through the third rotating shaft 3373. It should be understood that the other second connecting part 3323 of the first support plate 332 can also be rotatably connected to the second end 336b of the second connecting rod 336 through another third rotating shaft 3373. The specific connection method will not be described here.

[0216] In some embodiments, the first arc arm 333 may also have a mounting hole 3335. Figure 10The mounting hole 3335 of the first arc arm 333 is also shown. The mounting hole 3335 can be located between the first rotating end 333a and the second rotating end 333b of the first arc arm 333. The mounting hole 3335 can be located on the side of the first connecting rod 335 facing away from the first support plate 332, and is set directly opposite to the first connecting rod 335. In this way, when assembling the first connecting rod 335, the first arc arm 333, the first fixing frame 331 and the first support plate 332, it is possible to observe through the mounting hole 3335 of the first arc arm 333 whether the third rotating shaft 3373 is correspondingly inserted into the second end 335b of the first connecting rod 335, thereby ensuring the accuracy of assembly and ensuring that the folding mechanism 3 can move normally.

Multiple damping components 37 can have identical, symmetrical, or similar structures. In this embodiment, the number of damping components 37 can be two, for example, including a first damping component 37a and a second damping component 37b. The first damping component 37a and the second damping component 37b can be located on opposite sides of the synchronizing component 36. Both the first damping component 37a and the second damping component 37b can be connected to the connecting member via the fourth rotating shaft 38. It should be noted that, for the sake of simplicity, the following description will focus on one damping component 37 (e.g., the first damping component 37a) and its cooperation with the synchronizing component 36; the specific design of other damping components 37 will not be elaborated upon.

The first hole 3611 and the second hole 3612 of the connecting member 361 may be parallel and spaced apart. The connecting member 361 may also have a third hole 3613 and a fourth hole 3614. The third hole 3613 and the fourth hole 3614 of the connecting member 361 may both be located between the first end 361a and the second end 361b of the connecting member 361, that is, between the first hole 3611 and the second hole 3612 of the connecting member 361. The third hole 3613 and the fourth hole 3614 of the connecting member 361 can both be parallel to and set with the first hole 3611. That is, the first hole 3611, the second hole 3612, the third hole 3613 and the fourth hole 3614 of the connecting member 361 can all be set in parallel.

[0222] For example, the connecting member 361 may have two third holes 3613. Both third holes 3613 of the connecting member 361 may be blind holes, and the openings of the two third holes 3613 may be arranged opposite to each other.

The first hole 3611 of the first end 361a of the connecting member 361 may be coaxially arranged with the first rotation hole 3621 of the first synchronizing arm 362. One of the plurality of fourth rotating shafts 38 of the third component 35 may pass through the first rotation hole 3621 of the first synchronizing arm 362 and the first hole 3611 of the connecting member 361. That is, the first rotating end 362b of the first synchronizing arm 362 may be rotatably connected to the first end 361a of the connecting member 361 via the fourth rotating shaft 38. The first rotating end 362b of the first synchronizing arm 362 may be hinged to the first end 361a of the connecting member 361.

[0226] Exemplarily, the second end 361b of the connecting member 361 may be located within the second notch 3632 of the second synchronizing arm 363. The second hole 3612 of the second end 361b of the connecting member 361 may be coaxially arranged with the second rotation hole 3631 of the second synchronizing arm 363. One of the plurality of fourth rotating shafts 38 of the third component 35 may pass through the second rotation hole 3631 of the second synchronizing arm 363 and the second hole 3612 of the connecting member 361.

The two first gears 364 may be located on opposite sides of the connecting member 361, and respectively positioned opposite the two third holes 3613 of the connecting member 361.

[0229] Figure 26 yes Figure 22 The damping component 37 of the third component 35 shown is a structural schematic diagram in some embodiments. Figure 27 yes Figure 26 The diagram shows an exploded view of the damping component 37 in some embodiments.

[0230] like Figure 26 and Figure 27 As shown, the first damping assembly 37a may include a first connecting arm 371, a second connecting arm 372, a fixed base 373, a first intermediate member 374, a second intermediate member 375, multiple connecting shafts 376, multiple friction plates 377, and multiple springs 3781. The multiple friction plates 377 may include multiple first friction plates 3771, multiple second friction plates 3772, and multiple third friction plates 3773.

[0231] For example, each first friction plate 3771 may include a connecting hole 3771a and a rotating hole 3771b spaced apart. Each second friction plate 3772 may include a first hole 3772a, a second hole 3772b, a third hole 3772c, and a fourth hole 3772d spaced apart sequentially. Each third friction plate 3773 may include a connecting hole 3773a and a rotating hole 3773b spaced apart. Multiple second friction plates 3772 may be arranged in a manner that overlaps with multiple first friction plates 3771 sequentially. The first holes 3772a of the multiple second friction plates 3772 may be arranged in a manner that overlaps with the rotating holes 3771b of the multiple first friction plates 3771 sequentially, and are interconnected. The first holes 3772a of the second friction plates 3772 may be coaxially arranged with the rotating holes 3771b of the first friction plates 3771. Multiple second friction plates 3772 may also be arranged in a manner that overlaps with multiple third friction plates 3773 sequentially. The fourth holes 3772d of multiple second friction plates 3772 can be sequentially overlapped with the rotating holes 3773b of multiple third friction plates 3773, and are interconnected. The fourth holes 3772d of the second friction plates 3772 can be coaxially arranged with the rotating holes 3773b of the third friction plates 3773.

[0232] For example, the first connecting arm 371 may include a sliding end 371a and a rotating end 371b. The rotating end 371b of the first connecting arm 371 may have a third rotating hole 3711. The third rotating hole 3711 of the first connecting arm 371 may extend through the rotating end 371b of the first connecting arm 371. The first connecting arm 371 may also have a fourth rotating hole 3712 and a third notch 3713. The fourth rotating hole 3712 of the first connecting arm 371 may be located on the side of the third rotating hole 3711 near the sliding end 371a of the first connecting arm 371, and may be arranged parallel to the third rotating hole 3711. The third notch 3713 of the first connecting arm 371 may connect the third rotating hole 3711 and the fourth rotating hole 3712, and may extend from the fourth rotating hole 3712 to the end face of the rotating end 371b of the first connecting arm 371 away from the sliding end 371a.

[0233] For example, the second connecting arm 372 may include a sliding end 372a and a rotating end 372b.

The fifth rotating hole 3721 of the second connecting arm 372 may extend through the rotating end 372b of the second connecting arm 372. The second connecting arm 372 may also have a sixth rotating hole 3722 and a fourth notch 3723. The sixth rotating hole 3722 of the second connecting arm 372 may be located on the side of the fifth rotating hole 3721 near the sliding end 372a of the second connecting arm 372, and may be arranged parallel to the fifth rotating hole 3721. The fourth notch 3723 of the second connecting arm 372 may connect the fifth rotating hole 3721 and the sixth rotating hole 3722, and may extend from the sixth rotating hole 3722 to the end face of the rotating end 372b of the second connecting arm 372 away from the sliding end 372a.

[0234] For example, a plurality of first friction plates 3771 may be located within the third notch 3713 of the first connecting arm 371. The connecting hole 3771a of the first friction plate 3771 may be coaxially arranged with the fourth rotation hole 3712 of the first connecting arm 371. One of the plurality of connecting shafts 376 may pass through the connecting hole 3771a of the plurality of first friction plates 3771 and the fourth rotation hole 3712 of the first connecting arm 371. The rotation hole 3771b of the first friction plate 3771 may be coaxially arranged with the third rotation hole 3711 of the first connecting arm 371. In this case, the first hole 3772a of the second friction plate 3772 may also be coaxially arranged with the third rotation hole 3711 of the first connecting arm 371.

[0235] For example, a plurality of third friction plates 3773 may be located within the fourth notch 3723 of the second connecting arm 372. The connecting hole 3773a of the third friction plate 3773 may be coaxially arranged with the sixth rotating hole 3722 of the second connecting arm 372. One of the plurality of connecting shafts 376 may pass through the connecting hole 3773a of the plurality of third friction plates 3773 and the sixth rotating hole 3722 of the second connecting arm 372. The rotating hole 3773b of the third friction plate 3773 may be coaxially arranged with the fifth rotating hole 3721 of the second connecting arm 372. In this case, the fourth hole 3772d of the second friction plate 3772 may also be coaxially arranged with the fifth rotating hole 3721 of the second connecting arm 372.

[0236] like Figure 26 and Figure 27 As shown, the mounting base 373 may include a first hole 3731, a second hole 3732, a third hole 3733, and a fourth hole 3734 arranged sequentially at intervals. The first hole 3731, second hole 3732, third hole 3733, and fourth hole 3734 of the mounting base 373 may be parallel to each other and arranged at intervals. The mounting base 373 may also have a first clearance notch 3735 and a second clearance notch 3736. The first clearance notch 3735 of the mounting base 373 may connect to the first hole 3731 of the mounting base 373. The second clearance notch 3736 of the mounting base 373 may connect to the fourth hole 3734 of the mounting base 373. The mounting base 373 may also have a mounting hole 3737. The mounting hole 3737 of the mounting base 373 may be located between the first clearance notch 3735 and the second clearance notch 3736. The axial direction of the mounting hole 3737 of the mounting base 373 may be perpendicular to the axial direction of the first hole 3731 of the mounting base 373. By way of example, the first damping component 37a may also include a fastener 3782. The fastener 3782 may be a screw or the like. The fastener 3782 may be installed in the mounting hole 3737 of the mounting base 373.

[0237] For example, the rotating end 371b of a portion of the first connecting arm 371 can be located within the first clearance notch 3735 of the fixed base 373. The third rotating hole 3711 of the rotating end 371b of the first connecting arm 371 can be positioned directly opposite to the first hole 3731 of the fixed base 373 and coaxially aligned with it. The rotating end 372b of a portion of the second connecting arm 372 can be located within the second clearance notch 3736 of the fixed base 373. The fifth rotating hole 3721 of the rotating end 372b of the second connecting arm 372 can be positioned directly opposite to the fourth hole 3734 of the fixed base 373 and coaxially aligned with it. In this case, multiple friction plates 377 can be located on one side of the fixed base 373. The rotating holes 3771b of the first friction plate 3771 and the first holes 3772a of the second friction plate 3772 can both be coaxially aligned with the first hole of the fixed base 373. The second hole and the third hole of the second friction plate 3772 can be coaxially arranged with the second hole and the third hole of the fixed base 373, respectively. The rotating hole 3773b of the third friction plate 3773 and the fourth hole 3772d of the second friction plate 3772 can be coaxially arranged with the fourth hole 3734 of the fixed base 373.

[0238] For example, the first intermediate component 374 may include a first hole 3741, a second hole 3742, a third hole 3743, and a fourth hole 3744 arranged sequentially at intervals. The first hole 3741, the second hole 3742, the third hole 3743, and the fourth hole 3744 of the first intermediate component 374 may be arranged parallel to each other. For example, the first intermediate component 374 may also have a first clearance notch 3745 and a second clearance notch 3746. The first clearance notch 3745 of the first intermediate component 374 may connect to the first hole 3741 of the first intermediate component 374. The second clearance notch 3746 of the first intermediate component 374 may connect to the fourth hole 3744 of the first intermediate component 374.

[0239] For example, the first intermediate member 374 may be located on the side of the plurality of friction plates 377 facing away from the fixed base 373. The second hole 3742 and the third hole 3743 of the first intermediate member 374 may be coaxially arranged with the second hole 3772b and the third hole 3772c of the second friction plate 3772, respectively. The rotating end 371b of part of the first connecting arm 371 may also be located within the first clearance notch 3745 of the first intermediate member 374. The third rotating hole 3711 of the rotating end 371b of the first connecting arm 371 may also be coaxially arranged with the first hole 3741 of the first intermediate member 374. The rotating end 372b of part of the second connecting arm 372 may be located within the second clearance notch 3746 of the first intermediate member 374. The fifth rotating hole 3721 of the rotating end 372b of the second connecting arm 372 may also be coaxially arranged with the fourth hole 3744 of the first intermediate member 374.

[0240] For example, the number of springs 3781 can be four. All four springs 3781 can be located on the side of the first intermediate member 374 facing away from the friction plate 377. The spring holes of the four springs 3781 can be arranged one-to-one with the first hole 3741, the second hole 3742, the third hole 3743, and the fourth hole 3744 of the first intermediate member 374.

[0241] For example, the second intermediate member 375 may include a first hole 3751, a second hole 3752, a third hole 3753, and a fourth hole 3754 arranged sequentially at intervals. The first hole 3751, the second hole 3752, the third hole 3753, and the fourth hole 3754 of the second intermediate member 375 may be arranged parallel to each other. The second intermediate member 375 may be located on the side of the plurality of springs 3781 facing away from the first intermediate member 374. The first hole 3751, the second hole 3752, the third hole 3753, and the fourth hole 3754 of the second intermediate member 375 may be arranged one-to-one with the spring holes of the four springs 3781. The first hole 3751, the second hole 3752, the third hole 3753, and the fourth hole 3754 of the second intermediate member 375 may be arranged coaxially with the first hole 3741, the second hole 3742, the third hole 3743, and the fourth hole 3744 of the first intermediate member 374.

[0242] like Figure 26 and Figure 27 As shown, the rotating end 371b of the first connecting arm 371 facing the first intermediate member 374 may have multiple first protrusions 3714. The multiple first protrusions 3714 of the first connecting arm 371 may be spaced around the third rotating hole 3711 of the first connecting arm 371. The surface of the first intermediate member 374 facing the first connecting arm 371 may have multiple first mating protrusions 3747. The multiple first mating protrusions 3747 of the first intermediate member 374 may be spaced around the first hole 3741 of the first intermediate member 374. The multiple first mating protrusions 3747 of the first intermediate member 374 may correspond one-to-one with the multiple first protrusions 3714 of the first connecting arm 371.

[0243] For example, the rotating end 372b of the second connecting arm 372 facing the first intermediate member 374 may have a plurality of second protrusions 3724. The plurality of second protrusions 3724 of the second connecting arm 372 may be spaced around the fifth rotating hole 3721 of the second connecting arm 372. The surface of the first intermediate member 374 facing the second connecting arm 372 may have a plurality of second mating protrusions 3748. The plurality of second mating protrusions 3748 of the first intermediate member 374 may be spaced around the fourth hole 3744 of the first intermediate member 374. The plurality of second mating protrusions 3748 of the first intermediate member 374 may be correspondingly arranged one-to-one with the plurality of second protrusions 3724 of the second connecting arm 372.

[0244] Figure 28 yes Figure 8 The diagram shows an exploded view of the third component 35 in some embodiments. Figure 29 yes Figure 8 The diagram shows the structure of the third component 35 in some embodiments. Figure 30 yes Figure 29 The diagram shows the structure of the third component 35 from another perspective. It should be noted that... Figure 30 The perspective of the structure shown is Figure 29 The structure shown is viewed from the perspective of being flipped up and down.

[0245] like Figures 27 to 30 As shown, the multiple springs 3781 of the first damping assembly 37a can be respectively positioned opposite the first rotating end 362b of the first synchronizing arm 362, the first gear 364, the second gear 365, and the second rotating end 363b of the second synchronizing arm 363 of the synchronizing assembly 36. At this time, the multiple fourth rotating shafts 38 of the third assembly 35 can also be correspondingly inserted into the multiple holes of the second intermediate member 375, the multiple springs 3781, the multiple holes of the first intermediate member 374, the multiple holes of the second friction plate 3772, and the multiple holes of the fixing seat 373. The fourth rotating shaft 38 inserted into the first rotating end 362b of the first synchronizing arm 362 can also be inserted into the third rotating hole 3711 of the rotating end 371b of the first connecting arm 371 and the rotating hole 3771b of the first friction plate 3771. The fourth rotating shaft 38, which is mounted on the second rotating end 363b of the second synchronous arm 363, can also be inserted into the fifth rotating hole 3721 of the rotating end 372b of the second connecting arm 372 and the rotating hole 3773b of the third friction plate 3773.

[0246] Exemplarily, the third component 35 may further include a latch 39. The latch 39 may have a first latching groove 39a and a second latching groove 39b spaced apart. The latch 39 may be located on the side of the fixing base 373 facing away from the friction plate 377. The fourth rotating shaft 38 passing through the first rotating end 362b of the first synchronizing arm 362 may be clamped in the first latching groove 39a. The fourth rotating shaft 38 passing through the second rotating end 363b of the second synchronizing arm 363 may be clamped in the second latching groove 39b. In this way, the fourth rotating shaft 38 can be prevented from dislodging, which helps to ensure the connection stability of the third component 35.

[0247] For example, the surface of the second intermediate member 375 of the first damping component 37a facing the synchronization component 36 may have a plurality of third protrusions 3755. The plurality of third protrusions 3755 of the second intermediate member 375 may be arranged at intervals around the first hole 3751, the second hole 3752, the third hole 3753 and the fourth hole 3754 of the second intermediate member 375. The first rotating end 362b of the first synchronization arm 362, the first gear 364, the second gear 365 and the second rotating end 363b of the second synchronization arm 363 may each be provided with a plurality of third mating protrusions 3756, and may be arranged one-to-one with the plurality of third protrusions 3755 of the second intermediate member 375.

[0248] For example, the second damping component 37b can also be connected to the synchronization component 36 through the cooperation of multiple fourth rotating shafts 38. It should be understood that the connection methods of the second damping component 37b with the multiple fourth rotating shafts 38 and the synchronization component 36 can all refer to the relevant design of the first damping component 37a, and will not be repeated here. The second damping component 37b may include a first connecting arm 391, a second connecting arm 392, a fixed base 393, a first intermediate member 394, a second intermediate member 395, multiple connecting shafts 396, multiple friction plates 397, and multiple springs 3982. The first connecting arm 391 of the second damping component 37b may include a sliding end 391a and a rotating end 391b, and the second connecting arm 392 may include a sliding end 392a and a rotating end 392b.

[0249] Figure 31 yes Figure 7 The diagram shows the structure of the connecting component 32 in some embodiments. Figure 32 yes Figure 31 The diagram shows the structure of the connecting component 32, which conceals the first support plate 332 and the second support plate 342.

[0250] like Figure 29 , Figure 31 as well as Figure 32 As shown, the third component 35 may include a first set of connectors 351, a second set of connectors 352, and a main body connector 353. The first set of connectors 351 may include a rotating end 351a and a sliding end 351b. The rotating end 351a of the first set of connectors 351 is rotatably connected to the main body connector 353, and the sliding end 351b of the first set of connectors 351 is slidably connected to the first fixing frame 331 of the first component 33. The second set of connectors 352 may include a rotating end 352a and a sliding end 352b. The rotating end 352a of the second set of connectors 352 is rotatably connected to the main body connector, and the sliding end 352b of the second set of connectors 352 is slidably connected to the second fixing frame 341 of the second component 34.

[0251] In this embodiment, the first synchronizing arm 362 of the synchronizing component 36 of the third component 35, the first connecting arm 371 of the first damping component 37a, and the first connecting arm 391 of the second damping component 37b can collectively constitute the first set of connectors 351 of the third component 35. The second synchronizing arm 363 of the synchronizing component 36 of the third component 35, the second connecting arm 372 of the first damping component 37a, and the second connecting arm 392 of the second damping component 37b can collectively constitute the second set of connectors 352 of the third component 35. The structure connecting the first synchronizing arm 362 and the second synchronizing arm 363 in the synchronizing component 36, the structure connecting the first connecting arm 371 and the second connecting arm 372 in the first damping component 37a, and the structure connecting the first connecting arm 391 and the second connecting arm 392 in the second damping component 37b can collectively constitute the main body connector 353 of the third component 35.

[0252] The first rotating end 362b of the first synchronizing arm 362 of the synchronizing component 36, the rotating end 371b of the first connecting arm 371 of the first damping component 37a, and the rotating end 391b of the first connecting arm 391 of the second damping component 37b can together constitute the rotating end 351a of the first set of connectors 351. The first sliding end 362a of the first synchronizing arm 362 of the synchronizing component 36, the sliding end 371a of the first connecting arm 371 of the first damping component 37a, and the sliding end 391a of the first connecting arm 391 of the second damping component 37b can together constitute the sliding end 351b of the first set of connectors 351.

[0253] The second rotating end 363b of the second synchronizing arm 363 of the synchronizing assembly 36, the rotating end 372b of the second connecting arm 372 of the first damping assembly 37a, and the rotating end 392a of the second connecting arm 392 of the second damping assembly 37b can together constitute the rotating end 352a of the second set of connectors 352. The second sliding end 363a of the second synchronizing arm 363 of the synchronizing assembly 36, the second sliding end 372a of the second connecting arm 372 of the first damping assembly 37a, and the sliding end 392b of the second connecting arm 392 of the second damping assembly 37b can together constitute the sliding end 352b of the second set of connectors 352.

[0254] For example, the first fixing bracket 331 may also have a plurality of first sliding grooves 3313 ( Figure 12 The structure of the first slide groove 3313 is also illustrated. The guiding direction of multiple first slide grooves 3313 can be the same. The sliding end 371a of the first connecting arm 371 of the first damping component 37a, the first sliding end 362a of the first synchronizing arm 362 of the synchronizing component 36, and the sliding end 391a of the first connecting arm 391 of the second damping component 37b can be slidably connected to multiple first slide grooves 3313 in a one-to-one correspondence.

[0255] For example, the design of the second component 34 is largely the same as that of the first component 33, and the identical parts will not be described again. The second support plate 342 of the second component 34 may include a first connecting portion 3421 and a second connecting portion 3422. Figure 9 The structure of the second support plate 342 is also illustrated. The first connecting portion 3421 of the second support plate 342 can be rotatably connected to the second fixing frame 341; for example, the first connecting portion 3421 of the second support plate 342 can be hinged to the second fixing frame 341. There can be two second connecting portions 3422 of the second support plate 342, and the two second connecting portions 3422 of the second support plate 342 can be rotatably connected to one end of the third link 345 and one end of the fourth link 346, respectively. The other ends of the third link 345 and the fourth link 346 can be rotatably connected to the third arc arm 343 and the fourth arc arm 344, respectively.

[0256] For example, the second fixing frame 341 may have multiple second slide grooves 3411. The guiding directions of the multiple second slide grooves 3411 may be the same. The sliding end 372a of the second connecting arm 372 of the first damping assembly 37a, the second sliding end 363a of the second synchronizing arm 363 of the synchronizing assembly 36, and the sliding end 392a of the second connecting arm 392 of the second damping assembly 37b may be slidably connected to the multiple second slide grooves 3411 in a one-to-one correspondence.

[0257] Figure 33 yes Figure 7 The diagram shows an exploded view of the main shaft 31 in some embodiments. Figure 34 yes Figure 33 The diagram shows the structure of the main shaft 31 from another perspective. It should be noted that... Figure 34 The perspective of the structure shown is Figure 33 The structure shown is viewed from the perspective of being flipped up and down.

[0258] like Figure 33 and Figure 34 As shown, the spindle 31 may include a first spindle segment 311, a connecting segment 312, and a second spindle segment 313. The first spindle segment 311 and the second spindle segment 313 may have the same, symmetrical, or similar structures. One end of the connecting segment 312 may be fixedly connected to the first spindle segment 311, and the other end may be fixedly connected to the second spindle segment 313. For example, the connecting segment 312 may be fixedly connected to the first spindle segment 311 and the second spindle segment 313 by means of screwing, welding, snap-fitting, etc.

[0259] For example, taking the first spindle segment 311 as an example, the two ends of the first spindle segment 311 may respectively have a first active space 311a and a second active space 311b. The first spindle segment 311 may have a first arc-shaped groove 3111 and a second arc-shaped groove 3112. The first arc-shaped groove 3111 may connect to the first active space 311a. The second arc-shaped groove 3112 may connect to the second active space 311b. The center of curvature of the first arc-shaped groove 3111 and the center of curvature of the second arc-shaped groove 3112 may be coaxially arranged. The first spindle segment 311 may also have a third arc-shaped groove 3113 and a fourth arc-shaped groove 3114. The third arc-shaped groove 3113 may connect to the first active space 311a. The fourth arc-shaped groove 3114 may connect to the second active space 311b. The center of curvature of the third arc-shaped groove 3113 and the center of curvature of the fourth arc-shaped groove 3114 may be coaxially arranged. The curvature center of the first arc-shaped groove 3111 can be spaced apart from and parallel to the curvature center of the third arc-shaped groove 3113.

[0260] Figure 35 yes Figure 6 The diagram shows a partial structural schematic of the folding mechanism 3 in some embodiments. Figure 36 yes Figure 35 The diagram shown is a structural schematic from another perspective. Figure 37 yes Figure 35 The diagram shows a cross-sectional structure of one embodiment of the folding mechanism 3 cut along D1-D1. Figure 38 yes Figure 37 The diagram shown illustrates the structure in its closed state. It should be noted that this is for ease of understanding. Figure 36 The structure of decorative element 3a is hidden in the middle. Figure 36 The perspective of the structure shown is Figure 35 The structure shown is viewed from the perspective of being flipped up and down.

[0261] like Figures 35 to 38 As shown, the two connecting components 32 can be connected to the first spindle segment 311 and the second spindle segment 313 of the spindle 31, respectively (please refer to...). Figure 33 (As shown). Taking one of the connecting components 32 and the first spindle segment 311 as an example, the first arc arm 333 and the second arc arm 334 of the first component 33 of the connecting component 32 can be respectively installed in the first movable space 311a and the second movable space 311b of the first spindle segment 311 (please refer to...). Figure 33 (As shown). The second rotating end 333b of the first arc arm 333 and the second rotating end 334b ​​of the second arc arm 334 can both be rotatably connected to the first main shaft segment 311.

[0262] For example, in conjunction with reference Figure 37 and Figure 38As shown, the second rotating end 333b of the first arc arm 333 may have an arc-shaped protrusion 3334, which can be installed in the first arc-shaped groove 3111 of the first main shaft section 311. In this case, a virtual axis rotational connection structure can be formed between the second rotating end 333b of the first arc arm 333 and the main shaft 31. The second rotating end 334b ​​of the second arc arm 334 may have an arc-shaped protrusion 3341, which can be installed in the second arc-shaped groove 3112 of the first main shaft section 311. In this case, a virtual axis rotational connection structure can be formed between the second rotating end 334b ​​of the second arc arm 334 and the main shaft 31. The rotation center of the first arc arm 333 relative to the main shaft 31 and the rotation center of the second arc arm 334 relative to the main shaft 31 can be located on the same straight line.

[0263] Exemplarily, the third arc arm 343 and the fourth arc arm 344 of the second component 34 of the connecting component 32 can be respectively installed in the first movable space 311a and the second movable space 311b of the first spindle segment 311. It should be understood that the connection method between the second component 34 and the first spindle segment 311 can refer to the connection method between the first component 33 and the first spindle segment 311, and will not be repeated here. The third arc arm 343 may have an arc-shaped protrusion 3431, which can be installed in the third arc-shaped groove 3113 of the first spindle segment 311. In this case, a virtual axis rotational connection structure can be formed between the third arc arm 343 and the spindle 31. The fourth arc arm 344 may have an arc-shaped protrusion 3441, which can be installed in the fourth arc-shaped groove 3114 of the first spindle segment 311. In this case, a virtual axis rotational connection structure can be formed between the fourth arc arm 344 and the spindle 31. The rotation center of the third arc arm 343 relative to the main shaft 31 and the rotation center of the fourth arc arm 344 relative to the main shaft 31 can be located on the same straight line. The rotation center of the third arc arm 343 relative to the main shaft 31 can be parallel to and spaced apart from the rotation center of the first arc arm 333 relative to the main shaft 31.

[0264] For example, in conjunction with reference Figure 39 and Figure 40As shown, the third component 35 can be installed on the first spindle section 311. The main connecting member 353 of the third component 35 can be fixed to the first spindle section 311. In this embodiment, the connecting member 361 of the synchronization component 36 of the third component 35 can be fixed to the first spindle section 311 by means of screws or the like. For example, a screw can pass through the fixing hole 3615 of the connecting member 361 and be locked to the first spindle section 311. In this case, the first rotating end 362b of the first synchronizing arm 362 of the synchronization component 36 rotatably connecting to the connecting member 361 can also be considered as rotatably connecting to the spindle 31. The second rotating end 363b of the second synchronizing arm 363 of the synchronization component 36 rotatably connecting to the connecting member 361 can also be considered as rotatably connecting to the spindle 31. The damping component 37 of the third component 35 can also be fixed to the first spindle section 311 by means of screws or the like. For example, a screw can pass through the fixing hole 3737 of the first damping component 37a and be locked to the first spindle section 311. At this time, the rotating end 371b of the first connecting arm 371 of the first damping assembly 37a, which is rotatably connected to the fixed seat 373, can also be regarded as rotatably connected to the main shaft 31. The rotating end 372b of the second connecting arm 372 of the first damping assembly 37a, which is rotatably connected to the fixed seat 373, can also be regarded as rotatably connected to the main shaft 31.

[0265] For example, the folding mechanism 3 may also include a decorative element 3a ( Figure 7 The structure of the decorative element 3a is also illustrated. The decorative element 3a can be fixed to the side of the main shaft 31 facing away from the flexible display screen 20. The decorative element 3a can be used to cover the internal structure of the folding mechanism 3.

[0266] Figure 39 yes Figure 35 The diagram shows a cross-sectional view of one embodiment of the structure cut along D2-D2. Figure 40 yes Figure 39 The diagram shown is a schematic of the structure when it is in a closed state. Figure 41 yes Figure 35 The diagram shows a cross-sectional view of one embodiment of the structure cut along line D3-D3. Figure 42 yes Figure 41 The diagram shown is a schematic of the structure when it is in a closed state. Figure 43 yes Figure 35 The diagram shows a cross-sectional view of one embodiment of the structure cut along line D4-D4. Figure 44 yes Figure 43 The diagram shown is a schematic of the structure when it is in a closed state.

[0267] like Figures 39 to 44As shown, in this embodiment, the connecting component 32 can have a generally symmetrical structure, and the structure connecting both sides of the main shaft 31 can be generally symmetrical. In this embodiment, this refers to the first set of connecting pieces 351 between the first component 33 and the third component 35 (please refer to...). Figure 32 The structure connected to one side of the spindle 31 (as shown) can be connected to the second set of connectors 352 of the second component 34 and the third component 35 (please refer to...). Figure 32 The structure connected to the other side of the spindle 31 (as shown) is generally symmetrical. For the sake of simplicity, the following description will take the structure connected to one side of the spindle 31 (e.g., the first set of connectors 351 of the first component 33 and the third component 35) as an example.

[0268] For example, the first rotating end 333a of the first arc arm 333 can be rotatably connected to the first fixed frame 331, the second rotating end 333b of the first arc arm 333 can be rotatably connected to the main shaft 31, the first rotating end 362b of the first synchronous arm 362 can be rotatably connected to the main shaft 31, and the first sliding end 362a of the first synchronous arm 362 can be slidably connected to the first fixed frame 331. In this case, the first arc arm 333, the first fixed frame 331, the first synchronous arm 362, and the main shaft 31 can together constitute a crank-slider mechanism. The connection methods of the second arc arm 334 with the first fixed frame 331, the first synchronous arm 362, and the main shaft 31 can all refer to the connection methods of the first arc arm 333 with the first fixed frame 331, the first synchronous arm 362, and the main shaft 31; the same parts will not be described again. It should be understood that the movement of the first synchronous arm 362 is the same as the movement of the first set of connecting parts 351 of the third component 35. At this time, it can also be regarded that the first arc arm 333, the first fixed frame 331, the first set of connecting parts 351 and the main shaft 31 together constitute the crank-slider mechanism.

[0269] In this design, the first connecting portion 3322 of the first support plate 332 is rotatably connected to the first fixed frame 331, the second connecting portion 3323 of the first support plate 332 is rotatably connected to the second end 335b of the first connecting rod 335, and the first end 335a of the first connecting rod 335 is rotatably connected to the middle portion 333c of the first arc arm 333. At this time, the first support plate 332, the first fixed frame 331, the first connecting rod 335, and the first arc arm 333 together constitute a four-bar linkage. The connection method between the second arc arm 334 and the first support plate 332, the first fixed frame 331, and the first connecting rod 335 can be referenced to the connection method between the first arc arm 333 and the first support plate 332, the first fixed frame 331, and the first connecting rod 335; the same parts will not be described again.

[0270] It should be noted that the arrangement of the second set of connecting parts 352 and the main shaft 31 in the second component 34 and the third component 35 can refer to the arrangement of the first set of connecting parts 351 and the main shaft 31 in the first component 33 and the third component 35, and the same parts will not be repeated. The third arc arm 343, the second fixed frame 341, the second synchronous arm 363, and the main shaft 31 can together constitute a crank-slider mechanism. The fourth arc arm 344, the second fixed frame 341, the second synchronous arm 363, and the main shaft 31 can together constitute a crank-slider mechanism. It should be understood that the movement of the second synchronous arm 363 is the same as the movement of the second set of connecting parts 352 in the third component 35; in this case, the third arc arm 343, the second fixed frame 341, the second set of connecting parts 352, and the main shaft 31 can also be considered as the third arc arm 343, the second fixed frame 341, the second set of connecting parts 352, and the main shaft 31 together constituting a crank-slider mechanism. The second support plate 342, the second fixed frame 341, the third connecting rod 345, and the third arc arm 343 can together constitute a four-bar linkage. The second support plate 342, the second fixed frame 341, the fourth link 346, and the third arc arm 343 can together form a four-bar linkage.

[0271] The movement of the folding mechanism 3 will be described in detail below with reference to the accompanying drawings.

[0272] Figure 45 yes Figure 6 The diagram shows a simplified motion representation of the folding mechanism 3 in some embodiments. It should be noted that... Figure 45 Only the kinematic connection between the main shaft 31 of the folding mechanism 3 and the structure connected to one side of the main shaft 31 is shown.

[0273] like Figures 37 to 40 as well as Figure 45 As shown, during the process of the first fixed frame 331 and the second fixed frame 341 folding to a closed state, the first arc arm 333 can rotate out of the main shaft 31, the sliding end of the first synchronous arm 362 can slide out of the first fixed frame 331, and the first rotating end 362b of the first synchronous arm 362 can rotate relative to the main shaft 31. The movement of the first rotating end 362b of the first synchronous arm 362 can be transmitted to the second rotating end 363b of the second synchronous arm 363 through the first gear 364 and the second gear 365, so that the second rotating end 363b of the second synchronous arm 363 can rotate relative to the main shaft 31, and the direction of rotation of the second synchronous arm 363 relative to the main shaft 31 is opposite to the direction of rotation of the first synchronous arm 362 relative to the main shaft 31. The sliding end of the second synchronous arm 363 can slide out of the second fixed frame 341, and the third arc arm 343 can rotate out of the main shaft 31.

[0274] During the process of the first fixed frame 331 and the second fixed frame 341 unfolding to the open state, the first arc arm 333 can rotate into the main shaft 31, and the sliding end of the first synchronous arm 362 can slide into the first fixed frame 331, allowing the first synchronous arm 362 to rotate relative to the main shaft 31. The movement of the first synchronous arm 362 can be transmitted to the second synchronous arm 363 through the first gear 364 and the second gear 365, enabling the second synchronous arm 363 to rotate relative to the main shaft 31, with the rotation direction of the second synchronous arm 363 opposite to that of the first synchronous arm 362. The sliding end of the second synchronous arm 363 can slide into the second fixed frame 341, and the third arc arm 343 can rotate into the main shaft 31.

[0275] like Figures 41 to 45 As shown, during the process of the first fixed frame 331 and the second fixed frame 341 folding to a closed state, the first arc arm 333 can rotate out of the main shaft 31, and the first arc arm 333 can also rotate relative to the first fixed frame 331 along a first direction a. The first support plate 332 can rotate relative to the first fixed frame 331 along the first direction a, and the first connecting rod 335 can rotate relative to the first arc arm 333 along a second direction b. The first direction a and the second direction b can be opposite directions. The third arc arm 343 can rotate out of the main shaft 31, and the third arc arm 343 can also rotate relative to the second fixed frame 341 along the second direction b. The second support plate 342 can rotate relative to the second fixed frame 341 along the second direction b, and the third connecting rod 345 can rotate relative to the third arc arm 343 along the first direction a.

[0276] During the process of the first fixed frame 331 and the second fixed frame 341 unfolding to the open state, the first arc arm 333 can rotate into the main shaft 31, and the first arc arm 333 can also rotate relative to the first fixed frame 331 along the second direction b. The first support plate 332 can rotate relative to the first fixed frame 331 along the second direction b, and the first connecting rod 335 can rotate relative to the first arc arm 333 along the first direction a. The third arc arm 343 can rotate out of the main shaft 31, and the third arc arm 343 can also rotate relative to the second fixed frame 341 along the first direction a. The second support plate 342 can rotate relative to the second fixed frame 341 along the first direction a, and the third connecting rod 345 can rotate relative to the third arc arm 343 along the second direction b.

[0277] It is understood that in this embodiment, the first support plate 332 is hinged to the first fixing frame 331. The first support plate 332 can be rotatably connected to the first fixing frame 331 via a solid pivot (i.e., the first rotating shaft 3374 in this embodiment). Figure 43 and Figure 44(As shown). At this time, a solid shaft rotational connection structure can be formed between the first support plate 332 and the first fixed frame 331. In this way, by forming a solid shaft rotational connection structure between the first support plate 332 and the first fixed frame 331, it is beneficial to reduce the play generated when the first support plate 332 moves relative to the first fixed frame 331, improve the movement accuracy of the first support plate 332, and avoid the first support plate 332 shaking due to play. This would prevent the first support plate 332 from occupying the space of the flexible display screen 20 during shaking, causing the flexible display screen 20 to collide with the first support plate 332 during the drop, resulting in partial failure of the flexible display screen 20 and the generation of small black spots, which would affect the user experience.

[0278] Secondly, in this embodiment, the first support plate 332 can also be connected to the first arc arm 333 via the first connecting rod 335. In this way, the first support plate 332, the first connecting rod 335, the first arc arm 333, and the first fixing frame 331 can form a four-bar linkage, which is a low-pair structure. This is beneficial to improving the motion accuracy of the first support plate 332, further reducing the play generated when the first support plate 332 moves, and preventing the first support plate 332 from shaking.

[0279] Furthermore, the first component 33 in this embodiment includes a first arc arm 333 and a second arc arm 334. Both the first arc arm 333 and the second arc arm 334 can connect to the first fixing frame 331 and the main shaft 31, and the first arc arm 333 and the second arc arm 334 can respectively connect to the two ends of the first fixing frame 331. In this way, when the first fixing frame 331 moves relative to the main shaft 31, its movement is relatively smooth and will not cause lateral flipping. This effectively avoids the first fixing frame 331 from colliding with the flexible display screen 20 due to lateral flipping, which could cause partial failure of the flexible display screen 20 and the appearance of small black spots, affecting the user experience.

[0280] Figure 46 yes Figure 35 The diagram shows a cross-sectional view of one embodiment of the structure cut along line D5-D5. Figure 47 yes Figure 46 The diagram shown is a schematic of the structure when it is in a closed state.

[0281] like Figure 46 and Figure 47 As shown, the first support plate 332 may also have a limiting protrusion 3324. Figure 17 The structure of the limiting protrusion 3324 is also illustrated. The limiting protrusion 3324 can be fixed to the side of the support body 3321 facing the first fixing frame 331. The limiting protrusion 3324 can be set at an angle to the support body 3321. A gap 3325 can be formed between the limiting protrusion 3324 and the support body 3321. The first synchronizing arm 362 of the synchronizing assembly 36 can also have a mating protrusion 3624 ( Figure 24 The structure of the mating protrusion 3624 is also shown. The mating protrusion 3624 can be located on the side of the first synchronizing arm 362 near the first support plate 332.

[0282] When the folding mechanism 3 is in the open state, the limiting protrusion 3324 of the first support plate 332 can be spaced apart from the mating protrusion 3624 of the first synchronous arm 362. The limiting protrusion 3324 of the first support plate 332 can be located outside the gap 3325. When the folding mechanism 3 is in the closed state, the mating protrusion 3624 of the first synchronous arm 362 can be located within the gap 3325 of the first support plate 332 and abut against the limiting protrusion 3324 of the first support plate 332.

[0283] During the process of the first fixing frame 331 and the second fixing frame 341 folding to a closed state, the limiting protrusion 3324 of the first support plate 332 and the cooperating protrusion 3624 of the first synchronous arm 362 can approach each other, and the cooperating protrusion 3624 of the first synchronous arm 362 can extend into the gap 3325 between the limiting protrusion 3324 of the first support plate 332 and the support body 3321, and abut against the limiting protrusion 3324. During the process of the first fixing frame 331 and the second fixing frame 341 unfolding to an open state, the limiting protrusion 3324 of the first support plate 332 and the cooperating protrusion 3624 of the first synchronous arm 362 can move away from each other, and the cooperating protrusion 3624 of the first synchronous arm 362 can move out of the gap 3325 between the limiting protrusion 3324 of the first support plate 332 and the support body 3321.

[0284] It is understood that the first support plate 332 in this embodiment may also have a limiting protrusion 3324, and the first synchronizing arm 362 may also have a mating protrusion 3624. When the folding mechanism 3 is in the open state, the limiting protrusion 3324 and the mating protrusion 3624 may be spaced apart. When the folding mechanism 3 is in the closed state, the mating protrusion 3624 may extend into the gap 3325 between the limiting protrusion 3324 and the support body 3321, and abut against the limiting protrusion 3324. In this way, by setting the limiting protrusion 3324 to cooperate with the cooperating protrusion 3624, and setting the limiting protrusion 3324 and the cooperating protrusion 3624 to abut against each other when the folding mechanism 3 is in the closed state, the limiting protrusion 3324 and the cooperating protrusion 3624 can form an over-constrained fit when the folding mechanism 3 is in the closed state, thus forming an over-constrained fit structure to lock the posture of the first support plate 332. This can better prevent the first support plate 332 from shaking due to the mechanism's own looseness when the folding mechanism 3 is in the closed state, which would cause the first support plate 332 to collide with the flexible display screen and produce abnormal noise. It can also prevent the flexible display screen from partially failing due to the collision of the first support plate 332, resulting in small black spots and affecting the user experience.

[0285] In some implementation methods, please refer to Figure 29 As shown, the protrusion 3624 can also be formed on other structural components of the first set of connectors 351 of the third component 35.

[0286] In other embodiments, an over-constraint fit structure may also be provided between the second support plate 342 and the second set of connecting members 352 of the third component 35 to lock the posture of the second support plate 342 when the folding mechanism 3 is in the closed state, so as to prevent the second support plate 342 from shaking due to the vacancy of the mechanism itself.

[0287] The above text has described one embodiment of the folding mechanism 3. Below, with reference to the accompanying drawings, another embodiment of the folding mechanism 3 will be described in detail. In this embodiment, the connecting rod between the arc arm and the support plate of the folding mechanism 3 is eliminated. Figure 48 yes Figure 6 The diagram shows a structural schematic of the folding mechanism 3 in another embodiment. Figure 49 yes Figure 48 The diagram shows an exploded view of the folding mechanism 3 in some embodiments. Figure 50 yes Figure 49 The diagram shows an exploded view of the connecting component 32 of the folding mechanism 3 in some embodiments. Figure 51 yes Figure 50 The diagram shows the structure from another perspective. It should be noted that... Figure 51 The structural perspective shown is Figure 50 The structure shown is viewed from the perspective of being flipped up and down.

[0288] like Figures 48 to 51 As shown, the number of connecting components 32 in the folding mechanism 3 of this embodiment can also be two. The two connecting components 32 can be connected to both ends of the main shaft 31 respectively. For ease of description, the following description will use one connecting component 32 and its cooperation with the main shaft 31 as an example; the specific design of the other connecting components 32 will not be elaborated further. Additionally, the folding mechanism 3 of this embodiment may include... Figure 6 Most of the technical features shown are identical to those in both, and will not be repeated here. The connecting component 32 of the folding mechanism 3 may include a first component 33, a second component 34, and a third component 35. The following mainly describes some of the differences between the two.

[0289] Figure 52 yes Figure 50 A schematic diagram of the assembly structure of the first component 33 of the connecting component 32 in some embodiments. Figure 53 yes Figure 52 The diagram shown is a structural schematic from another perspective. Figure 54 yes Figure 52The diagram shows a partial cross-sectional view of one embodiment of the connecting component 32 cut along EE. It should be noted that... Figure 53 The perspective of the structure shown is Figure 52 The structure shown is viewed from the perspective of being flipped up and down.

[0290] like Figures 50 to 54 As shown, the first rotating end 333a of the first arc arm 333 and the first connecting part 3322 of the first support plate 332 can both be rotatably connected to the first fixed frame 331. The rotation center of the first arc arm 333 relative to the first fixed frame 331 can coincide with the rotation center of the first support plate 332 relative to the first fixed frame 331.

[0291] For example, the first fixing frame 331 may not include the second rotating body. The plurality of rotating shafts 337 of the first component 33 may also not include the second and third rotating shafts. One of the plurality of rotating shafts 337 of the first component 33, the first rotating shaft 3374, may pass through the first hole 3331 of the first rotating end 333a of the first arc arm 333 and the first rotating hole 3311 of the first rotating body 331a of the first fixing frame 331. That is, the first rotating end 333a of the first arc arm 333 can be rotatably connected to the first rotating body 331a of the first fixing frame 331 via the first rotating shaft 3374.

[0292] The first rotating end 333a of the first arc arm 333 can be hinged to the first rotating body 331a of the first fixed frame 331.

[0293] For example, the first rotating shaft 3374, which passes through the first rotating body 331a of the first fixed frame 331, can also pass through the first hole 3327a of the first connecting portion 3322 of the first support plate 332. That is, the first connecting portion 3322 of the first support plate 332 can be rotatably connected to the first rotating body 331a of the first fixed frame 331 via the first rotating shaft 3374. The first rotating end 333a of the first arc arm 333 can be hinged to the first rotating body 331a of the first fixed frame 331. At this time, the first support plate 332 and the first arc arm 333 can both be rotatably connected to the first rotating body 331a of the first fixed frame 331 via the same solid rotating shaft (i.e., the first rotating shaft 3374 in this embodiment). The rotation center of the first arc arm 333 relative to the first fixed frame 331 and the rotation center of the first support plate 332 relative to the first fixed frame 331 can both be the axis of the first rotating shaft 3374.

[0294] It should be noted that the arrangement of the second arc arm 334 and the first fixing frame 331 of the first component 33 can refer to the arrangement of the first arc arm 333 and the first fixing frame 331 of the first component 33, and the same parts will not be repeated here. Specifically, the rotation center of the second arc arm 334 of the first component 33 relative to the first fixing frame 331 can be located on the same straight line as the rotation center of the first arc arm 333 relative to the first fixing frame 331.

[0295] It should be noted that the structural design of the second component 34 is roughly the same as that of the first component 33, and will not be described in detail here.

[0296] Figure 55 yes Figure 50 The diagram shows the structure of the third component 35 of the connecting component 32 in some embodiments. Figure 56 yes Figure 55 The diagram shows an exploded view of the third component 35 in some embodiments.

[0297] like Figure 55 and Figure 56 As shown, in this embodiment, the synchronization component and damping component of the third component 35 can be modularly designed, that is, the synchronization component and damping component can be integrated into a single module. The third component 35 may include a first connecting module 354, a second connecting module 355, multiple damping springs 356, and multiple fourth rotating shafts 38. The multiple damping springs 356 can be arranged side-by-side and located between the first connecting module 354 and the second connecting module 355. The multiple fourth rotating shafts 38 can be sequentially inserted through the first connecting module 354, the multiple damping springs 356, and the second connecting module 355. The structural designs of the first connecting module 354 and the second connecting module 355 are largely the same; for simplicity, the following description uses the first connecting module 354 as an example.

[0298] Figure 57 yes Figure 56 The diagram shows an exploded view of the first connection module 354 in some embodiments.

[0299] like Figure 55 and Figure 57 As shown, the first connecting module 354 may include a first movable member 51, a second movable member 52, a fixed base 53, an intermediate member 54, multiple friction plates 55, a first gear 56, and a second gear 57. The multiple friction plates 55 may include multiple first friction plates 551, multiple second friction plates 552, and multiple third friction plates 553. Each first friction plate 551 may include a connecting hole 551a and a rotating hole 551b spaced apart. Each third friction plate 553 may have a connecting hole 553a and a rotating hole 553b spaced apart.

[0300] Exemplarily, the first movable member 51 may include a rotating end 51a and a sliding end 51b. The rotating end 51a of the first movable member 51 may include a first rotating arm 511 and a second rotating arm 512 spaced apart. A first notch 513 is formed between the first rotating arm 511 and the second rotating arm 512 of the first movable member 51. The second movable member 52 may include a rotating end 52a and a sliding end 52b. The rotating end 52a of the second movable member 52 may include a first rotating arm 521 and a second rotating arm 522 spaced apart. A second notch 523 is formed between the first rotating arm 521 and the second rotating arm 522 of the second movable member 52. The second movable member 52 may also have a second movable body 524. The second movable body 524 may be located between the rotating end 52a and the sliding end 52b of the second movable member 52.

[0301] For example, the first rotating arm 511 of the first movable member 51 can mesh with the first gear 56, the first gear 56 can mesh with the second gear 57, and the second gear 57 can mesh with the first rotating arm 521 of the second movable member 52. A portion of the plurality of fourth rotating shafts 38 can be respectively connected to the rotating end 51a of the first movable member 51, the first gear 56, the second gear 57, and the rotating end 52a of the second movable member 52. In this way, the first movable member 51 and the second movable member 52 can achieve motion transmission by meshing with one first gear 56 and one second gear 57 respectively.

[0302] For example, a plurality of first friction plates 551 may be located within a first notch 513 of a first movable member 51. One of a plurality of fourth rotating shafts 38 may pass through a connection hole 551a between the first movable member 51 and the plurality of first friction plates 551 to mount the plurality of first friction plates 551 onto the first movable member 51. A plurality of third friction plates 553 may be located within a second notch 523 of a second movable member 52. One of the plurality of fourth rotating shafts 38 may pass through a connection hole 553a between the second movable member 52 and the plurality of third friction plates 553 to mount the plurality of third friction plates 553 onto the second movable member 52. The plurality of second friction plates 552 may be sequentially overlapped with the plurality of first friction plates 551 located within the first notch 513 of the first movable member 51 and the plurality of second friction plates 552 located within the second notch 523 of the second movable member 52. The fourth rotating shaft 38, which passes through the rotating end 51a of the first movable member 51, can also pass through the rotating holes 551b of multiple first friction plates 551 and multiple second friction plates 552. The fourth rotating shaft 38 passing through the first gear 56 and the fourth rotating shaft 38 passing through the second gear 57 can also both pass through multiple second friction plates 552. The fourth rotating shaft 38, which passes through the rotating end 52a of the second movable member 52, can also pass through the rotating holes 553b of multiple third friction plates 553 and multiple second friction plates 552.

[0303] Exemplarily, the fixing seat 53 may be located on the side of the first gear 56 and the second gear 57 facing away from the plurality of friction plates 55. The fixing seat 53 may have a fixing hole 531. The intermediate member 54 may be located on the side of the plurality of friction plates 55 facing away from the fixing seat 53. A portion of the intermediate member 54 overlaps the surface of the rotating end 51a of the first movable member 51 facing away from the friction plate 55 (in this embodiment, it may be the surface of the second rotating arm 512 of the first movable member 51 facing away from the friction plate 55). A portion of the intermediate member 54 also overlaps the surface of the rotating end 52a of the second movable member 52 facing away from the friction plate 55 (in this embodiment, it may be the surface of the second rotating arm 522 of the second movable member 52 facing away from the friction plate 55). A plurality of fourth rotating shafts 38 may all pass through the fixing seat 53 and the intermediate member 54. A plurality of damping springs 356 may be located on the side of the intermediate member 54 facing away from the fixing seat 53.

[0304] For example, the surface of the intermediate member 54 facing the first movable member 51 may have a plurality of first protrusions 541 spaced apart around the fourth rotating shaft 38. The surface of the second rotating arm 512 of the first movable member 51 facing the intermediate member 54 may have a plurality of first mating protrusions 5121. The plurality of first mating protrusions 5121 may be located one-to-one in the gaps between the plurality of first protrusions 541 of the intermediate member 54. The surface of the intermediate member 54 facing the second movable member 52 may have a plurality of second protrusions 542 around the fourth rotating shaft 38. The surface of the second rotating arm 522 of the second movable member 52 facing the intermediate member 54 may have a plurality of second mating protrusions 5221. The plurality of second mating protrusions 5221 may be arranged one-to-one corresponding to the plurality of second protrusions 542 of the intermediate member 54.

[0305] Exemplarily, the first connecting module 354 may further include a latch 58. The latch 58 of the first connecting module 354 may be located between the fixed base 53 and the plurality of friction pads 55. The latch 58 of the first connecting module 354 may have a first latch 581 and a second latch 582. The fourth rotating shaft 38 passing through the rotating end 51a of the first movable member 51 may be clamped in the first latch 581. The fourth rotating shaft 38 passing through the rotating end 52a of the second movable member 52 may be clamped in the second latch 582.

[0306] It should be noted that, for the sake of simplicity, the design of the second connecting module 355 can refer to the design of the first connecting module 354, and the same parts will not be described again. The second connecting module 355 may include a first movable member 61, a second movable member 62, a fixed base 63, an intermediate member 64, multiple friction plates 65, a first gear 66, and a second gear 67. The first movable member 61 of the second connecting module 355 may include a rotating end 61a and a sliding end 61b, and the second movable member 62 may include a rotating end 62a and a sliding end 62b.

[0307] In this embodiment, the first movable member 51 of the first connecting module 354 and the first movable member 61 of the second connecting module 355 can together constitute the first set of connectors 351 of the third component 35. The second movable member 52 of the first connecting module 354 and the second movable member 62 of the second connecting module 355 can together constitute the second set of connectors 352 of the third component 35. The structure in the first connecting module 354 connecting the first movable member 51 and the second movable member 52 and the structure in the second connecting module 355 connecting the first movable member 61 and the second movable member 62 can together constitute the main body connector 353 of the third component 35.

[0308] The rotating end 51a of the first movable member 51 of the first connecting module 354 and the rotating end 61a of the first movable member 61 of the second connecting module 355 can together constitute the rotating end 351a of the first set of connecting members 351. The sliding end 51b of the first movable member 51 of the first connecting module 354 and the sliding end 61b of the first movable member 61 of the second connecting module 355 can together constitute the sliding end 351b of the first set of connecting members 351.

[0309] The rotating end 52a of the second movable member 52 of the first connecting module 354 and the rotating end 62a of the second movable member 62 of the second connecting module 355 can together constitute the rotating end 352a of the second set of connecting members 352. The sliding end 52b of the second movable member 52 of the first connecting module 354 and the sliding end 62b of the second movable member 62 of the second connecting module 355 can together constitute the sliding end 352b of the second set of connecting members 352.

[0310] Figure 58 yes Figure 56 The diagram shows the assembly structure of the third component 35 and the spindle 31 in some embodiments. Figure 59 yes Figure 58 The diagram shows the structure from another perspective. It should be noted that... Figure 59 The perspective of the structure shown is Figure 58 The structure shown is viewed from the perspective of being flipped up and down.

[0311] like Figure 58 and Figure 59 As shown, the third component 35 can be installed on the spindle 31. The main connecting member 353 of the third component 35 can be fixed to the spindle 31. In this embodiment, the fixing seat 53 of the first connecting module 354 of the third component 35 can be fixed to the spindle 31 by means of screws or other methods. For example, a screw can pass through the fixing hole 531 of the fixing seat 53 of the third component 35 and be locked to the spindle 31. In this case, the rotating end 51a of the first movable member 51 and the rotating end 52a of the second movable member 52 of the first connecting module 354 can both be considered as rotatably connected to the spindle 31. Similarly, the rotating end 61a of the first movable member 61 and the rotating end 62a of the second movable member 62 of the second connecting module 355 can both be considered as rotatably connected to the spindle 31.

[0312] Figure 60 yes Figure 48 A partial structural schematic diagram of the folding mechanism 3 shown. Figure 61 yes Figure 60 The diagram shows a cross-sectional view of one embodiment of the structure cut along F1-F1. Figure 62 yes Figure 61 The diagram shown is a schematic of the structure when it is in a closed state. Figure 63 yes Figure 60 The diagram shows a cross-sectional view of one embodiment of the structure cut along F2-F2. Figure 64 yes Figure 63 The diagram shown is a schematic of the structure when it is in a closed state.

[0313] like Figures 60 to 64 As shown, in this embodiment, the sliding end 51b of the first movable member 51 of the first connecting module 354 can be slidably connected to the first fixed frame 331, and the sliding end 52b of the second movable member 52 of the first connecting module 354 can be slidably connected to the second fixed frame 341. The first rotating end 333a of the first arc arm 333 is rotatably connected to the first fixed frame 331, and the second rotating end 333b of the first arc arm 333 is rotatably connected to the main shaft 31. The sliding end 51b of the first movable member 51 is slidably connected to the first fixed frame 331, and the rotating end 51a of the first movable member 51 is rotatably connected to the main shaft 31. At this time, the first arc arm 333, the first fixed frame 331, the first movable member 51, and the main shaft 31 can together constitute a crank-slider mechanism. The connection methods of the second arc arm 334 with the first fixed frame 331, the first movable member 51, and the main shaft 31 can all refer to the connection methods of the first arc arm 333 with the first fixed frame 331, the first movable member 51, and the main shaft 31, and the same parts will not be described again. It should be understood that the movement of the first movable member 51 is related to the first set of connecting members 351 of the third component 35 (please refer to...). Figure 55 The motion is the same as shown in the figure. At this time, it can also be regarded that the first arc arm 333, the first fixed frame 331, the first set of connecting parts 351 and the main shaft 31 together constitute the crank slider mechanism.

[0314] It should be noted that the second set of connectors 352 of the second component 34 and the third component 35 (please refer to...) Figure 55 The arrangement of the main shaft 31 (as shown) can be referenced from the arrangement of the second set of connecting parts 352 and the main shaft 31 of the first component 33 and the third component 35, and the same parts will not be repeated. A crank-slider mechanism can also be formed between the third arc arm 343 of the second component 34, the second movable part 52 of the first connecting module 354, the second fixed frame 341, and the main shaft 31. A crank-slider mechanism can also be formed between the fourth arc arm 344 of the second component 34, the second movable part 52 of the first connecting module 354, the second fixed frame 341, and the main shaft 31. It should be understood that the movement of the second movable arm 52 of the first connecting module 354 is the same as the movement of the second set of connecting parts 352 of the third component 35. In this case, the third arc arm 343, the second fixed frame 341, the second set of connecting parts 352, and the main shaft 31 can also be considered as jointly constituting a crank-slider mechanism.

[0315] Figure 65 yes Figure 60 The diagram shows a cross-sectional view of one embodiment of the structure cut along F3-F3. Figure 66 yes Figure 65 The diagram shown is a schematic of the structure when it is in a closed state.

[0316] like Figure 65 and Figure 66 As shown, the first movable body 514 of the first movable member 51 is movably connected to the second connecting portion 3323 of the first support plate 332, and is capable of rotating and sliding relative to the first connecting portion 3322 of the first support plate 332. That is, the first support plate 332 can roll relative to the first movable member 51. Exemplarily, the second connecting portion 3323 of the first support plate 332 may have an arc-shaped groove 3326. The first movable body 514 of the first movable member 51 may have a rotating hole 5141. The connecting assembly 32 may also have a mounting shaft 32a. The mounting shaft 32a may pass through the rotating hole 5141 of the first movable member 51 and the arc-shaped groove 3326 of the first support plate 332.

At this time, the first support plate 332, the first fixed frame 331, and the first movable member 51 can together constitute a crank rolling mechanism. That is, the first support plate 332, the first fixed frame 331, and the first set of connecting members 351 can together constitute a crank rolling mechanism.

[0318] For example, the second movable member 52 of the first connecting module 354 may further have a second movable body 524. The second movable body 524 may be located between the rotating end 52a and the sliding end 52b of the second movable member 52 of the first connecting module 354. The second movable body 524 may be movably connected to the second connecting portion 3422 of the second support plate 342, and may rotate and slide relative to the second connecting portion 3422 of the second support plate 342. That is, the second support plate 342 may roll relative to the second movable member 52 of the first connecting module 354. The connection method between the second movable member 52 and the second support plate 342 can be referred to the connection method between the first movable member 51 and the first support plate 332, and will not be described again here.

At this time, the second support plate 342, the second fixed frame 341, and the second movable member 52 of the first connecting module 354 can together constitute a crank rolling mechanism.

[0320] The movement of the folding mechanism 3 will be described in detail below with reference to the accompanying drawings.

[0321] Figure 67 yes Figure 60 The diagram shows a cross-sectional view of one embodiment of the structure cut along F4-F4. Figure 68 yes Figure 67 The diagram shown is a schematic of the structure when it is in a closed state. Figure 69 yes Figure 48 The diagram shows a simplified motion representation of the folding mechanism 3 in some embodiments. It should be noted that... Figure 69 Only the kinematic connection between the main shaft 31 of the folding mechanism 3 and the structure connected to one side of the main shaft 31 is shown.

[0322] like Figures 60 to 69 As shown, during the process of the first fixed frame 331 and the second fixed frame 341 folding to a closed state, the first arc arm 333 can rotate out of the main shaft 31, the sliding end 51b of the first movable member 51 can slide out of the first fixed frame 331, and the rotating end 51a of the first movable member 51 can rotate relative to the main shaft 31. The movement of the rotating end 51a of the first movable member 51 can be transmitted to the rotating end 52a of the second movable member 52 through the first gear 56 and the second gear 57, so that the rotating end 52a of the second movable member 52 can rotate relative to the main shaft 31, and the direction of rotation of the second movable member 52 relative to the main shaft 31 can be opposite to the direction of rotation of the first movable member 51 relative to the main shaft 31. The sliding end 52b of the second movable member 52 can slide out of the second fixed frame 341, and the third arc arm 343 can rotate out of the main shaft 31.

[0323] The first movable member 51 can rotate relative to the main shaft 31 along a first direction a. The first movable body 514 of the first movable member 51 can roll relative to the second connecting portion 3323 of the first support plate 332 along a direction close to the main shaft 31, and rotate relative to the second connecting portion 3323 of the first support plate 332. The first support plate 332 can rotate relative to the first fixed frame 331 along a second direction b. The second movable member 52 can rotate relative to the main shaft 31 along a second direction b. The second movable body 524 of the second movable member 52 can slide relative to the second connecting portion 3422 of the second support plate 342 along a direction close to the main shaft 31, and rotate relative to the second connecting portion 3422 of the second support plate 342. The second support plate 342 can rotate relative to the second fixed frame 341 along a first direction a.

[0324] During the process of the first fixed frame 331 and the second fixed frame 341 unfolding to the open state, the first arc arm 333 can rotate into the main shaft 31, the sliding end 51b of the first movable member 51 can slide into the first fixed frame 331, and the rotating end 51a of the first movable member 51 can rotate relative to the main shaft 31. The movement of the rotating end 51a of the first movable member 51 can be transmitted to the rotating end 52a of the second movable member 52 through the first gear 56 and the second gear 57, so that the rotating end 52a of the second movable member 52 can rotate relative to the main shaft 31, and the direction of rotation of the second movable member 52 relative to the main shaft 31 can be opposite to the direction of rotation of the first movable member 51 relative to the main shaft 31. The sliding end 52b of the second movable member 52 can slide into the second fixed frame 341, and the third arc arm 343 can rotate into the main shaft 31.

[0325] The first movable member 51 can rotate relative to the main shaft 31 along the second direction b. The first movable body 514 of the first movable member 51 can slide relative to the second connecting portion 3323 of the first support plate 332 in a direction away from the main shaft 31, and rotate relative to the second connecting portion 3323 of the first support plate 332. The first support plate 332 can rotate relative to the first fixed frame 331 along the first direction a. The second movable member 52 can rotate relative to the main shaft 31 along the first direction a. The second movable body 524 of the second movable member 52 can slide relative to the second connecting portion 3422 of the second support plate 342 in a direction away from the main shaft 31, and rotate relative to the second connecting portion 3422 of the second support plate 342. The second support plate 342 can rotate relative to the second fixed frame 341 along the second direction b.

[0326] It is understood that, in this embodiment, a solid shaft rotational connection structure can be formed between the first support plate 332 and the first fixed frame 331 of the folding mechanism 3, and a solid shaft connection structure can also be formed between the first arc arm 333 and the first fixed frame 331. In this way, on the one hand, forming a solid shaft rotational connection structure between the first support plate 332 and the first fixed frame 331 helps to reduce the play generated when the first support plate 332 moves relative to the first fixed frame 331; on the other hand, forming a solid shaft connection structure between the first arc arm 333 and the first fixed frame 331 helps to reduce the play generated when the first arc arm 333 moves relative to the first fixed frame 331. In this embodiment, by reducing the misalignment of the first support plate 332 and the first arc arm 333 during movement, the movement accuracy of the first support plate 332 and the folding mechanism 3 can be effectively improved. This can better prevent the first support plate 332 from shaking due to misalignment, which would cause the first support plate 332 to occupy the space of the flexible display screen 20 during shaking. This would cause the flexible display screen 20 to collide with the first support plate 332 during the fall, resulting in partial failure of the flexible display screen 20 and the generation of small black spots, which would affect the user experience.

[0327] Secondly, in this embodiment, both the first support plate 332 and the first arc arm 333 can be rotatably connected to the first fixing frame 331 via the same solid pivot (which in this embodiment is also the first rotating shaft 3374). Figure 61 , Figure 62 , Figure 67 as well as Figure 68 (As shown). In this way, on the one hand, a solid shaft rotational connection structure can be formed between the first support plate 332 and the first fixed frame 331, which helps to reduce the play generated when the first support plate 332 moves relative to the first fixed frame 331, improve the motion accuracy of the first support plate 332, and make the trajectory control of the first support plate 332 more precise; on the other hand, the first support plate 332 and the first arc arm 333 are rotatably connected to the first fixed frame 331 through the same solid shaft, which helps to simplify the mechanism and simplify the assembly process.

[0328] In some embodiments, the first support plate 332 and the first arc arm 333 may be rotatably connected to the first fixing frame 331 via different physical pivots. The rotation center of the first support plate 332 relative to the first fixing frame 331 may be coaxially arranged with the rotation center of the first arc arm 333 relative to the first fixing frame 331.

That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0331] The above are merely some embodiments of this application, and the scope of protection of this application is not limited thereto.
