Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to a rotating mechanism and a foldable electronic device. Background Art

[0002] With technological advancements, the design (ID) of electronic devices (such as mobile phones and tablets) is trending from candy-bar devices to foldable devices. Foldable devices offer large screens when open, fully satisfying consumers' visual experience, while being compact and portable when closed. However, existing foldable devices struggle to achieve hovering during opening and closing, failing to meet user requirements. Summary of the Invention

[0003] The present application provides a rotation mechanism and a foldable electronic device to solve the technical problem in the prior art that foldable electronic devices are difficult to achieve hovering during the rotation process.

[0004] In a first aspect, the present application provides a rotation mechanism comprising: a fixed base, a first fixed plate, a second fixed plate and a damping assembly. The damping assembly comprises a first damping swing arm, a second damping swing arm and a first damping member. The first damping swing arm and the second damping swing arm are respectively mounted on opposite sides of the fixed base in the width direction and are rotatably connected to the fixed base. The first fixed plate is slidably connected to the first damping swing arm, and the first fixed plate can rotate relative to the fixed base, and the second fixed plate is slidably connected to the second damping swing arm, and the second fixed plate can rotate relative to the fixed base. The first damping member is mounted on the first fixed plate and elastically supports the first damping swing arm, so that the first damping swing arm drives the first fixed plate to hover at a preset angle.

[0005] The preset angle refers to the angle between the first fixing plate and the second fixing plate when the first fixing plate is suspended, that is, the deployment angle of the rotating mechanism. The preset angle ranges from 0 to 180 degrees.

[0006] A rotating mechanism is used in a foldable electronic device, which includes a first housing, a second housing, and a display screen. The first housing is fixedly connected to a first fixing plate, and the second housing is fixedly connected to a second fixing plate. The rotating mechanism is located between the first housing and the second housing and rotatably connects the first and second housings. Rotation of the rotating mechanism can drive relative rotation of the first and second housings. The first and second housings are also provided with accommodating grooves for accommodating electronic components and structural elements of the electronic device, such as a processor, circuit board, and camera module. When the rotating mechanism is in a folded state, the first and second fixing plates are folded relative to each other. That is, the first and second fixing plates rotate toward each other so that the first and second fixing plates are stacked. When the rotating mechanism is in a flattened state, the first and second fixing plates are flattened relative to the fixed base, and the angle between the first and second fixing plates is close to 180 degrees.

[0007] When the foldable electronic device is in a folded state, the display screen bends. When the foldable electronic device is in a flattened state, the display screen unfolds, providing a large display area, enabling a large-screen display for the foldable electronic device and improving the user experience. The first damping oscillator and the second damping oscillator rotate simultaneously, and the first and second damping oscillators rotate in opposite directions.

[0008] In this embodiment, by providing a first damping member and elastically abutting the first damping swing arm, the first damping member provides a damping force to the first damping swing arm when the first damping swing arm rotates, thereby preventing the first damping swing arm from rotating and providing a damping feel for the user. Furthermore, the damping force provided by the first damping member to the first damping swing arm's rotation enables the first damping swing arm to hover at a preset angle, thereby causing the first damping swing arm to cause the first fixing plate to hover, and thus causing the first housing to hover, thereby enhancing the user experience.

[0009] In one embodiment, the first damping swing arm includes a first side surface, and the first damping member includes a first elastic body and a first abutting body, wherein the first elastic body is connected to the first abutting body. When the first fixing plate rotates relative to the fixing base, the first abutting body slides along the first side surface and abuts the first side surface, thereby compressing the first elastic body. The elastic extension direction of the first elastic body is parallel to the length direction of the fixing base.

[0010] It should be noted that, the “elastic extension direction of the first elastomer is parallel to the length direction of the fixed base” mentioned here means that the angle between the elastic extension direction of the first elastomer and the length direction of the fixed base is 0, and it may also mean that there is some deviation between the elastic extension direction of the first elastomer and the length direction of the fixed base.

[0011] When the first fixed plate rotates, the first abutting body slides along the first side surface and always abuts the first side surface. The first abutting body is subjected to the abutting force of the first damping swing arm, compressing the first elastic body and causing the first elastic body to be in a compressed state. When the first elastic body is in a compressed state, it has an elastic restoring force, which causes the first abutting body to have a movement tendency toward the first side surface, so that the first abutting body abuts the first side surface to prevent the rotation of the first damping swing arm, thereby providing a damping force for the rotation of the first damping swing arm, and further providing a damping feel for the user, thereby improving the user's experience. In addition, the first damping member provides a damping force for the rotation of the first damping swing arm, which can cause the first damping swing arm to hover at a preset angle, thereby causing the first damping swing arm to drive the first fixed plate to hover, thereby driving the first shell to achieve hovering, thereby improving the user's experience.

[0012] Moreover, in this embodiment, by arranging the first elastic body and the first abutting body on the first damping member, the elastic force generated by the first elastic body can make the first abutting body abut against the first side surface, thereby providing damping force for the first damping swing arm, and the structure is simple.

[0013] In one embodiment, the first abutting body includes a first column and a first abutting block. The first column includes a first abutting end and a first free end. The first abutting end and the first free end are arranged opposite each other. The first abutting block is located on the outer periphery of the first column and is fixedly connected to the first column. The first elastic body is sleeved on the outer periphery of the first column and contacts the first abutting block, with the first abutting end facing away from the first elastic body. When the first fixed plate rotates relative to the fixed base, the first abutting end moves along the first side surface and abuts the first side surface. The first abutting block compresses the first elastic body to put the first elastic body into a compressed state.

[0014] When the first fixed plate rotates, the first abutting end of the first column slides along the first side surface and always abuts the first side surface. The first abutting end is subjected to the abutting force of the first damping swing arm, and drives the first abutting block to move through the first column, and causes the first abutting block to compress the first elastic body, so that the first elastic body is in a compressed state. When the first elastic body is in a compressed state, it has an elastic restoring force, which causes the first abutting block to have a movement tendency toward the first side surface, thereby causing the first column to have a movement tendency toward the first side surface, so that the first abutting end abuts the first side surface, thereby preventing the rotation of the first damping swing arm, providing a damping force for the rotation of the first damping swing arm, and further providing a damping feel for the user. At the same time, the first damping swing arm and the first fixed plate are suspended to enhance the user experience.

[0015] In one embodiment, the damping assembly further includes a second damping member, which is mounted on the second fixed plate and elastically supports the second damping swing arm, so that the second damping swing arm drives the second fixed plate to hover at a preset angle.

[0016] The preset angle may also refer to the angle between the second fixed plate and the first fixed plate when the second fixed plate is suspended, that is, the deployment angle of the rotating mechanism. In this embodiment, by providing a second damping member and making the second damping member abut against the second damping swing arm, when the second damping swing arm rotates, the second damping member can provide a damping force for the second damping swing arm to prevent the second damping swing arm from rotating, thereby providing a damping feel for the user. Furthermore, the damping force provided by the second damping member for the rotation of the second damping swing arm can cause the second damping swing arm to hover at a preset angle, thereby causing the second damping swing arm to drive the second fixed plate to hover, thereby driving the second shell to achieve hovering. That is, the second damping member can cause the rotating mechanism and the foldable electronic device to hover at a preset angle, thereby further enhancing the user experience.

[0017] In one embodiment, the second damping swing arm includes a second side surface, and the second damping member includes a second elastic body and a second abutting body, wherein the second elastic body is connected to the second abutting body. When the second fixing plate rotates relative to the fixing base, the second abutting body slides along the second side surface and abuts the second side surface, thereby compressing the second elastic body. The elastic extension direction of the second elastic body is parallel to the length direction of the fixing base.

[0018] It should be noted that, the “elastic extension direction of the second elastomer is parallel to the length direction of the fixed base” mentioned here means that the angle between the elastic extension direction of the second elastomer and the length direction of the fixed base is 0, and it may also mean that there is some deviation between the elastic extension direction of the second elastomer and the length direction of the fixed base.

[0019] When the second fixed plate rotates, the second abutting body slides along the second side surface and always abuts the second side surface. The second abutting body is subjected to the abutting force of the second damping swing arm, compressing the second elastic body and placing the second elastic body in a compressed state. When in a compressed state, the second elastic body has an elastic restoring force, which causes the second abutting body to move toward the second side surface, thereby causing the second abutting body to abut the second side surface and prevent rotation of the second damping swing arm. This provides a damping force for the rotation of the second damping swing arm, thereby providing a damping feel to the user and further enhancing the user experience.

[0020] Furthermore, the damping force provided by the second damping member to the rotation of the second damping swing arm can cause the second damping swing arm to hover at a preset angle, thereby causing the second damping swing arm to cause the second fixing plate to hover, and thus the second housing to hover. In other words, the second damping member can cause the rotating mechanism and the foldable electronic device to hover at a preset angle, further enhancing the user experience.

[0021] In this embodiment, by arranging the second elastic body and the second abutting body on the second damping member, the elastic force generated by the second elastic body can make the second abutting body abut against the second side surface, thereby providing damping force for the second damping swing arm, and the structure is simple.

[0022] In one embodiment, the damping assembly also includes a third damping member, and the third damping member includes a first hinge, and the first hinge is installed on the fixed base; the first damping swing arm includes a first hinge body, and the first damping swing arm is installed on the fixed base, and the first hinge body is hinged to the first hinge; when the first damping swing arm rotates relative to the fixed base, the first hinge body resists the first hinge and causes the first hinge to generate elastic force.

[0023] In this embodiment, a first hinge is provided on the first damping swing arm, and a first hinge member cooperating with the first hinge is provided, so that when the first damping swing arm rotates, the first hinge resists the first hinge member and causes the first hinge member to generate an elastic force. The elastic restoring force generated by the elastic force in turn acts on the first hinge member to prevent the first hinge member from rotating, thereby providing a damping force for the rotation of the first damping swing arm, so as to further enhance the damping feel when the user uses it and improve the user's experience.

[0024] In one embodiment, the first hinged member includes a first elastic member and a first hinge seat, the first hinge seat being fixedly connected to the first elastic member, an end of the first elastic member remote from the first hinge seat being fixedly connected to the fixed base, and the first hinge seat being hingedly connected to the first hinge body. When the first damping swing arm rotates relative to the fixed base, the first hinge body repeatedly pushes the first hinge seat, thereby repeatedly compressing the first elastic member.

[0025] In this embodiment, by arranging the first hinge seat and the first elastic member on the first hinge body, when the first damping swing arm rotates relative to the fixed base, the first hinge body repeatedly pushes the first hinge seat, so that the first elastic member is repeatedly compressed, so that the first elastic member continuously provides damping force for the rotation of the first damping swing arm, thereby further improving the damping feel.

[0026] In one embodiment, the first hinge body includes a plurality of alternating protrusions and recesses, and the first hinge seat includes a plurality of alternating protrusions and recesses. The protrusion of the first hinge body is located within the recess of the first hinge seat, and the protrusion of the first hinge seat is located within the recess of the first hinge body, so that the first damping swing arm is positioned relative to the fixed base. When the first hinge body rotates relative to the first hinge seat, the protrusion of the first hinge body abuts against the protrusion of the first hinge seat, causing the first hinge seat to move away from the first hinge body and compress the first elastic member.

[0027] When the rotating mechanism is in the folded and flattened states, the protrusion of the first hinged body is located within the recess of the first hinged seat, and the protrusion of the first hinged seat is located within the recess of the first hinged body. In this embodiment, the damping force provided by the third damping member continuously changes during the rotation of the first damping swing arm. When the rotating mechanism rotates to the folded and flattened states, the damping force provided by the third damping member is minimized, and the user can feel the change in damping force, thereby providing a locked feeling when the device is fully flattened and fully folded.

[0028] In one embodiment, the third damping member further includes a second hinged member, which is mounted on the fixed base and spaced apart from and parallel to the first hinged member. The second damping swing arm includes a second hinged body, which is mounted on the fixed base and hingedly connected to the second hinged member. When the second damping swing arm rotates relative to the fixed base, the second hinged body abuts against the second hinged member, causing the second hinged member to generate an elastic force.

[0029] In this embodiment, a second hinge is provided on the second damping swing arm, and a second hinge member cooperating with the second hinge is provided, so that when the second damping swing arm rotates, the second hinge member resists the second hinge member and causes the second hinge member to generate an elastic force. The elastic restoring force generated by the elastic force in turn acts on the second hinge member to prevent the second hinge member from rotating, thereby providing a damping force for the rotation of the second damping swing arm, so as to further enhance the damping feel when the user uses it and improve the user's experience.

[0030] In one embodiment, the third damping member includes a synchronous gear, a first rotating rod, and a second rotating rod. The first rotating rod and the second rotating rod are spaced apart and arranged side by side and fixedly connected to the synchronous gear. The first damping swing arm is fixedly connected to the first rotating rod, and the second damping swing arm is fixedly connected to the second rotating rod. When the first damping swing arm rotates relative to the fixed base, it drives the first rotating rod to rotate, and the second rotating rod is driven to rotate via the synchronous gear, thereby driving the second damping swing arm to rotate.

[0031] In this embodiment, a synchronous gear, a first rotating rod and a second rotating rod are provided, so that when the first fixed plate drives the first damping swing arm to rotate, the first damping swing arm can drive the synchronous gear to rotate through the first rotating rod, so that the synchronous gear drives the second rotating rod to rotate, thereby driving the second damping swing arm to rotate, and then driving the second fixed plate to rotate, so as to achieve synchronous rotation of the first fixed plate and the second fixed plate, thereby improving the convenience and reliability of the rotation of the rotating mechanism and enhancing the user experience.

[0032] The portion connecting the first rotating rod and the first damping swing arm is a flat shaft segment, and the portion connecting the second rotating rod and the second damping swing arm is a flat shaft segment. In this embodiment, by providing the flat shaft segment on the first rotating rod, the first damping swing arm and the first rotating rod are fixedly connected, thereby simplifying the structure of the rotating mechanism. Furthermore, by providing the flat shaft segment on the second rotating rod, the second damping swing arm and the second rotating rod are fixedly connected, further simplifying the structure of the rotating mechanism.

[0033] In one embodiment, the damping assembly further includes a damping plate, which is sleeved on the outer circumference of the first rotating rod and the second rotating rod, and the first rotating rod and the second rotating rod can rotate relative to the damping plate.

[0034] In this embodiment, multiple damping plates are provided. These plates are arranged in sequence along the length of the fixed base. When the first and second damping swing arms rotate relative to the fixed base, they drive the first and second rotating rods to rotate, generating a damping force between the first and second rotating rods and the damping plates. This damping force prevents the first and second damping swing arms from rotating, allowing the user to clearly feel the damping force generated by the damping plates, further enhancing the user's experience.

[0035] In one embodiment, the fixed base is provided with a first rotation groove and a second rotation groove, the first rotation groove and the second rotation groove being arranged opposite each other. The rotation mechanism includes a first main swing arm and a second main swing arm, the first main swing arm being mounted in the first rotation groove and capable of sliding along the first rotation groove, and being rotationally connected to the first fixed plate; the second main swing arm being mounted in the second rotation groove and capable of sliding along the second rotation groove, and being rotationally connected to the second fixed plate.

[0036] When the first housing rotates relative to the fixed base, it drives the first fixed plate to rotate, thereby driving the first main swing arm to rotate within the first rotation slot. When the second housing rotates relative to the fixed base, it drives the second fixed plate to rotate, thereby driving the second main swing arm to rotate within the second rotation slot, thereby folding or unfolding the rotation mechanism, thereby ensuring the rotational stability of the rotation mechanism and the foldable electronic device.

[0037] In one embodiment, the rotating mechanism includes a first auxiliary swing arm and a second auxiliary swing arm, the first auxiliary swing arm is rotatably connected to the fixed base, and is slidably and rotatably connected to the first fixed plate; the second auxiliary swing arm is rotatably connected to the fixed base, and is slidably and rotatably connected to the second fixed plate.

[0038] In this embodiment, by providing a first auxiliary swing arm, when the first fixed plate rotates relative to the fixed base, the first auxiliary swing arm is driven to rotate together with the first main swing arm, thereby enabling the first fixed plate to rotate relative to the fixed base, thereby increasing the stability of the first fixed plate's rotation. By providing a second auxiliary swing arm, when the second fixed plate rotates relative to the fixed base, the second auxiliary swing arm is driven to rotate together with the second main swing arm, thereby enabling the second fixed plate to rotate relative to the fixed base, thereby increasing the stability of the second fixed plate's rotation.

[0039] In one embodiment, the rotating mechanism further includes a first pressure plate and a second pressure plate, wherein the first pressure plate is slidably connected to the first fixed plate, and when the first fixed plate rotates relative to the fixed base, the first pressure plate can be driven to rotate relative to the fixed base; the second pressure plate is slidably connected to the second fixed plate, and when the second pressure plate rotates relative to the fixed base, the second pressure plate can be driven to rotate relative to the fixed base.

[0040] The first and second pressure plates are both positioned opposite the display screen, jointly supporting the display screen and thereby increasing the stability of the display screen connection, ensuring a smooth display. In this embodiment, the first pressure plate rotates by rotating the first fixed plate, which in turn rotates the second fixed plate, thereby achieving folding and unfolding of the display screen. Furthermore, by slidingly connecting the first pressure plate to the first fixed plate, and the second pressure plate to the second fixed plate, the angle between the first and second pressure plates is adjustable, thereby adapting to the folding angle of the foldable portion of the display screen.

[0041] In one embodiment, the rotating mechanism also includes a first pressure plate swing arm and a second pressure plate swing arm, wherein one end of the first pressure plate swing arm is rotationally connected to the fixed base, and the other end is slidingly connected to the first pressure plate; one end of the second pressure plate swing arm is rotationally connected to the fixed base, and the other end is slidingly connected to the second pressure plate.

[0042] In this embodiment, a first pressure plate swing arm is provided, and the first pressure plate drives the first pressure plate swing arm to rotate, thereby enabling the first pressure plate to rotate relative to the fixed base, thereby improving the stability of the first pressure plate's rotation. Furthermore, a second pressure plate swing arm is provided, and the second pressure plate drives the second pressure plate swing arm to rotate, thereby enabling the second pressure plate to rotate relative to the fixed base, thereby improving the stability of the second pressure plate's rotation.

[0043] In one embodiment, the rotating mechanism further includes a floating plate mounted on a fixed base, wherein an elastic member is disposed within the fixed base, wherein one end of the elastic member is fixedly connected to the bottom plate and the other end is fixedly connected to the floating plate, and wherein the elastic extension direction of the elastic member is parallel to the thickness direction of the fixed base.

[0044] When the rotating mechanism is in the unfolded state, the first and second pressure plate swing arms support the floating plate, and the floating plate pulls the elastic member to elastically extend the elastic member. When the rotating mechanism is in the folded state, the foldable portion of the display screen bends and bulges outward toward the floating plate. The first and second pressure plate swing arms release the floating plate, and the elastic member elastically retracts to its natural state. The elastic force of the elastic member drives the floating plate toward the fixed base to avoid the display screen and prevent the floating plate from squeezing the display screen and causing damage. Of course, when the rotating mechanism is in the folded state, the elastic member can also be compressed under the weight of the floating plate. In one embodiment, the main swing arm or the auxiliary swing arm can also support or release the floating plate to achieve movement of the floating plate in the thickness direction.

[0045] On the other hand, the present application also provides a foldable electronic device, including a first shell, a second shell, a display screen and the above-mentioned rotating mechanism, wherein the rotating mechanism is connected between the first shell and the second shell, and the display screen is installed on the first shell, the second shell and the rotating mechanism. When the rotating mechanism rotates, the first shell and the second shell rotate relative to each other, thereby driving the display screen to bend or unfold.

[0046] In this embodiment, a rotating mechanism having a first damping member is provided, and the first damping member provides a damping force for the rotation of the rotating mechanism, thereby providing a damping force for the rotation of the foldable electronic device, thereby improving the damping feel of the user when using the foldable electronic device and enhancing the user's usage experience.

[0047] In summary, this application provides a first damping member and elastically abuts the first damping arm, so that when the first damping arm rotates, the first damping member can provide a damping force to the first damping arm to prevent the first damping arm from rotating, thereby providing a damping feel for the user. Furthermore, the damping force provided by the first damping member to the first damping arm's rotation can cause the first damping arm to hover at a preset angle, thereby causing the first damping arm to cause the first fixed plate to hover, and thus causing the first housing to achieve hovering, thereby improving the user experience.

Foldable phones have large screens when open, fully satisfying consumers' visual experience. When closed, they are compact and easy to carry. However, foldable phones in the prior art cannot provide users with a damping feel during rotation. The rotation mechanism provided in this application can provide users with a damping feel during rotation, allowing users to obtain tactile feedback, thereby improving the user experience.

The foldable portion 330 is located between the first portion 310 and the second portion 320, and the foldable portion 330 can be bent along the Y direction. The first portion 310, the second portion 320, and the foldable portion 330 together constitute the display screen 300.

The display screen 300 is mounted on the folding device 200, and the mounting surface 350 is fixedly connected to the folding device 200. Specifically, the first housing 210 supports the first portion 310 of the display screen 300, and the second housing 220 supports the second portion 320. In other words, the first portion 310 is mounted on the first housing 210, and the second portion 320 is mounted on the second housing 220. The rotating mechanism 100 is disposed opposite the foldable portion 330. The first shell 210 and the second shell 220 can rotate relative to each other through the rotating mechanism 100, so that the folding device 200 can switch between the folded state and the flattened state.

[0081] Combine Figure 1 The first housing 210 and the second housing 220 rotate relative to each other via the rotation mechanism 100. As the first housing 210 and the second housing 220 approach each other, the display screen 300 folds, thereby folding the foldable electronic device 500. When the foldable electronic device 500 is in the folded state, the foldable portion 330 of the display screen 300 bends, and the first portion 310 and the second portion 320 are positioned relative to each other. At this point, the display screen 300 is located between the first housing 210 and the second housing 220, significantly reducing the probability of damage to the display screen 300 and effectively protecting the display screen 300.

[0082] Please also refer to Figure 2 and Figure 4 The first shell 210 and the second shell 220 rotate relative to each other via the rotating mechanism 100, and the first shell 210 and the second shell 220 move away from each other, driving the display screen 300 to unfold, so that the foldable electronic device 500 is unfolded to a semi-expanded state. When the foldable electronic device 500 is in the semi-expanded state, the first shell 210 and the second shell 220 unfold to an angle α, the first part 310 and the second part 320 unfold relative to each other, and drive the foldable part 330 to unfold. At this time, the angle between the first part 310 and the second part 320 is α. In this embodiment, α is 90 degrees. In other embodiments, α may also be approximately 90 degrees, or may be 80 degrees, 85 degrees, 95 degrees, or 100 degrees, etc.

[0083] Please also refer to Figure 3 and Figure 4The first housing 210 and the second housing 220 rotate relative to each other via the rotating mechanism 100. As the first housing 210 and the second housing 220 move away from each other, the display screen 300 further unfolds until the foldable electronic device 500 is flattened. When the folding device 200 is in the flattened state, the angle between the first housing 210 and the second housing 220 is β. The foldable portion 330 unfolds, and the first portion 310 and the second portion 320 unfold relative to each other. At this point, the angles between the first portion 310, the second portion 320, and the foldable portion 330 are all β. The display screen 300 has a large display area, enabling a large-screen display for the foldable electronic device 500 and improving the user experience. In this embodiment, β is 180 degrees. In other embodiments, β may also be approximately 180 degrees, such as 170 degrees, 175 degrees, 185 degrees, or 190 degrees.

[0084] It should be noted that angles α and β are both the angles between the first housing 210 and the second housing 220. These angles are used to distinguish the angles between the first housing 210 and the second housing 220 in different states of the foldable electronic device 500. Angle α refers to the angle between the first housing 210 and the second housing 220 when the foldable electronic device 500 is in the semi-expanded state; angle β refers to the angle between the first housing 210 and the second housing 220 when the foldable electronic device 500 is in the flattened state.

[0085] See also Figure 5 and Figure 6 , Figure 5 yes Figure 4 The schematic structural diagram of the rotating mechanism 100 in the foldable electronic device 500 is shown. Figure 6 yes Figure 5 Schematic diagram of the exploded structure of the rotating mechanism 100 is shown.

[0086] The rotating mechanism 100 includes a fixed base 10, a rotating assembly 1, a damping assembly 2, a pressure plate assembly 60 and a floating plate 70. The floating plate 70 is mounted on the fixed base 10, and the floating plate 70 can move in the Z direction relative to the fixed base 10.

The rotating assembly 1 is mounted on the fixed base 10, and can rotate relative to the fixed base 10 so that the fixed base 10 is rotationally connected to the rotating assembly 1. The damping assembly 2 is mounted on the fixed base 10 and is slidably connected to the rotating assembly 1. When the rotating assembly 1 rotates relative to the fixed base 10, it drives the pressure plate assembly 60 and the damping assembly 2 to rotate relative to the fixed base 10, thereby realizing the rotation of the rotating mechanism 100, so that the rotating mechanism 100 can switch between the folded and flattened states.

[0087] Please continue reading Figure 5 and Figure 6For the convenience of description, the present application sets a central axis O. The central axis O is parallel to the Z direction and passes through the center of the rotating mechanism 100. The rotating mechanism 100 is symmetrical about the central axis O.

[0088] In this embodiment, there are three rotating assemblies 1, which are arranged at intervals along the Y direction. The three rotating assemblies 1 are respectively a first rotating assembly 101, a second rotating assembly 101A, and a third rotating assembly 101B.

The first fixed plate 21, the first main swing arm 31, and the first secondary swing arm 41 are located on one side of the fixed base 10, while the second fixed plate 22, the second main swing arm 32, and the second secondary swing arm 42 are located on the other side of the fixed base 10. The first main swing arm 31 is rotationally connected to the first fixed plate 21, and the first secondary swing arm 41 is slidingly and rotationally connected to the first fixed plate 21. When the first fixed plate 21 rotates relative to the fixed base 10, it drives the first main swing arm 31 and the first secondary swing arm 41 to rotate relative to the fixed base 10. The second main swing arm 32 is rotatably connected to the second fixing plate 22, and the second auxiliary swing arm 42 is slidably and rotatably connected to the second fixing plate 22. When the second fixing plate 22 rotates relative to the fixed base 10, the second main swing arm 32 and the second auxiliary swing arm 42 are driven to rotate relative to the fixed base 10.

[0090] The second rotating assembly 101A and the first rotating assembly 101 can be identical or similar components, symmetrical or partially symmetrical structures, or different structures. In this embodiment, the second rotating assembly 101A is centrosymmetrical with the first rotating assembly 101 about the central axis O, and the second rotating assembly 101A is mounted on the negative side of the fixed base 10 in the Y-axis direction.

The fixed plate 20B includes a first fixed plate 21B and a second fixed plate 22B, and the main swing arm 30B includes a first main swing arm 31B and a second main swing arm 32B. The first fixed plate 21B and the first main swing arm 31B are located on one side of the fixed base 10, while the second fixed plate 22B and the second main swing arm 32B are located on the other side of the fixed base 10. The first main swing arm 31B is rotationally connected to the first fixed plate 21B, and the second main swing arm 32B is rotationally connected to the second fixed plate 22B. When the first fixed plate 21B rotates relative to the fixed base 10, it drives the first main swing arm 31B to rotate relative to the fixed base 10. When the second fixed plate 22B rotates relative to the fixed base 10, it drives the second main swing arm 32B to rotate relative to the fixed base 10. Specifically, the structures of the components of the third rotating assembly 101B, as well as their connections to the fixed base 10 and the pressure plate, can refer to the relevant description of the first rotating assembly 101. In other embodiments, the third rotating assembly 101B may also include a first auxiliary swing arm and a second auxiliary swing arm. The first auxiliary swing arm in the third rotating assembly 101B may have a structure identical or similar to the first auxiliary swing arm 41 in the first rotating assembly 101, and the second auxiliary swing arm in the third rotating assembly 101B may have a structure identical or similar to the second auxiliary swing arm 42 in the first rotating assembly 101.

The pressure plate swing arm 602 is mounted on the fixed base 10 and is rotatably connected to the fixed base 10. When the rotating assembly 1 rotates relative to the fixed base 10, the fixed plate 20 in the first rotating assembly 101, the fixed plate 20A in the second rotating assembly 101A, and the fixed plate 20B in the third rotating assembly 101B all rotate relative to the fixed base 10, jointly driving the pressure plate 601 to rotate relative to the fixed base 10, and the pressure plate 601 slides relative to the fixed plates 20, 20A, and 20B. At the same time, the pressure plate 601 drives the pressure plate swing arm 602 to rotate relative to the fixed base 10.

[0093] The damping assembly 2 is mounted on the fixed base 10 and is slidably connected to the fixed plate 20. In this embodiment, there are two damping assemblies 2.

The first damping assembly 50 is slidably connected to the fixed plate 20 in the first rotating assembly 101, and the second damping assembly 50A is slidably connected to the fixed plate 20A in the second rotating assembly 101A. When the first rotating assembly 101 rotates relative to the fixed base 10, the first damping assembly 50 provides a damping force. When the second rotating assembly 101A rotates relative to the fixed base 10, the second damping assembly 50A provides a damping force. During the rotation of the foldable electronic device 500, the damping assembly 2 provides a damping force, allowing users to experience a better damping feel while enabling the foldable electronic device 500 to hover at a preset angle, thereby enhancing the user experience.

[0112] The second main swing arm 32 is offset from the first main swing arm 31 in the Y direction, and the second auxiliary swing arm 42 is offset from the first auxiliary swing arm 41 in the Y direction. The second rotating body 321 of the second main swing arm 32 is mounted in the second rotating groove 122, and the second slide rail 128 is located in the second sliding groove 324. The second rotating body 321 can slide and rotate along the second slide rail 128 in the second rotating groove 122. The second rotating shaft 323 is mounted in the second sleeve 222 of the second fixed plate 22 and can rotate within the second sleeve 222. The second auxiliary swing arm 42 and the second main swing arm 32 are spaced apart in the Y direction. The second auxiliary shaft seat 421 is mounted on the first rotating shaft 123, and the second auxiliary swing body 422 is mounted in the third slide groove 225 and can slide and rotate within the third slide groove 225. The second fixed plate 22 is fixedly connected to the second housing 220.

[0113] Rotation of the first housing 210 relative to the fixed base 10 drives the first fixed plate 21 to rotate relative to the fixed base 10, thereby rotating the first main swing arm 31, causing the first rotating shaft 313 to rotate within the first sleeve 212, and the first rotating body 311 to rotate within the first rotating groove 121. Simultaneously, the first fixed plate 21 also drives the first auxiliary swing arm 41 to rotate, causing the first auxiliary swing body 412 to slide within the first slot 215, and the first auxiliary shaft seat 411 to rotate relative to the first rotating shaft 123. Rotation of the second housing 220 relative to the fixed base 10 drives the second fixed plate 22 to rotate relative to the fixed base 10, thereby rotating the second main swing arm 32, causing the second rotating shaft 323 to rotate within the second sleeve 222, and the second rotating body 321 to rotate within the second rotating groove 122. Simultaneously, the second fixed plate 22 also drives the second auxiliary swing arm 42 to rotate, causing the second auxiliary swing body 422 to slide within the third slot 225, and the second auxiliary shaft seat 421 to rotate relative to the second rotating shaft 124. Among them, the rotation direction of the first fixed plate 21 is opposite to the rotation direction of the second fixed plate 22, the rotation direction of the first main swing arm 31 is opposite to the rotation direction of the second main swing arm 32, and the rotation direction of the first auxiliary swing arm 41 is opposite to the rotation direction of the second auxiliary swing arm 42.

[0114] For example, when the rotating mechanism 100 switches from the flat state to the folded state, the first fixing plate 21, the first main swing arm 31, and the first auxiliary swing arm 41 rotate clockwise, and the second fixing plate 22, the second main swing arm 32, and the second auxiliary swing arm 42 rotate counterclockwise. When the rotating mechanism 100 switches from the folded state to the flat state, the first fixing plate 21, the first main swing arm 31, and the first auxiliary swing arm 41 rotate counterclockwise, and the second fixing plate 22, the second main swing arm 32, and the second auxiliary swing arm 42 rotate clockwise.

[0115] In this embodiment, by providing a first fixing plate 21 and a second fixing plate 22, and by fixing the first fixing plate 21 to the first housing 210 and the second fixing plate 22 to the second housing 220, the connection strength between the fixing plate 20 and the housing is increased, thereby improving the rotational stability of the foldable electronic device 500. By providing a first main swing arm 31 and a second main swing arm 32, the first and second fixing plates 21, 22 can rotate relative to the fixed base 10. Furthermore, by providing a first auxiliary swing arm 41, when the first fixing plate 21 rotates relative to the fixed base 10, the first auxiliary swing arm 41 and the first main swing arm 31 rotate together, thereby enabling the first fixing plate 21 to rotate relative to the fixed base 10, thereby improving the rotational stability of the first fixing plate 21. By providing a second auxiliary swing arm 42, when the second fixing plate 22 rotates relative to the fixed base 10, the second auxiliary swing arm 42 and the second main swing arm 32 rotate together, thereby enabling the second fixing plate 22 to rotate relative to the fixed base 10, thereby improving the rotational stability of the second fixing plate 22.

The first damping swing arm 51 and the second damping swing arm 52 are both rotationally and slidably connected to the fixed plate 20 in the first rotating assembly 101. The third damping member 56 is mounted within the fixed base 10 and is hingedly connected to the first damping swing arm 51 and the second damping swing arm 52. The first damping member 54 is mounted within the first fixed plate 21 in the first rotating assembly 101 and elastically abuts the first damping swing arm 51, allowing the first damping swing arm 51 to drive the first fixed plate 21 to hover at a preset angle. The second damping member 55 is installed in the second fixing plate 22 of the first rotating assembly 101 and elastically abuts against the second damping swing arm 52 so that the second damping swing arm 52 drives the second fixing plate 22 to hover at a preset angle.

[0118] The preset angle refers to the angle between the first fixing plate 21 and the second fixing plate 22 when the first fixing plate 21 or the second fixing plate 22 is suspended, that is, the deployment angle of the rotating mechanism 100. The preset angle ranges from 0 to 180 degrees.

[0133] Please also refer to Figure 14 and Figure 15 , Figure 14 yes Figure 5 The partial structural diagram of the rotating mechanism 100 is shown in FIG. Figure 15 yes Figure 5The diagram shows a partial structure of the rotating mechanism 100 at another angle.

[0134] The first damping swing arm 51 is mounted on the first rotating rod 561 and is slidably and rotatably connected to the first fixed plate 21. The first damping shaft seat 512 and the third damping shaft seat 513 are sleeved around the outer periphery of the first rotating rod 561 and are fixedly connected to the first rotating rod 561. The first hinge 564 and the portion of the fixing sleeve 563 connected to the first hinge 564 are located within the first receiving notch 516. The first hinge 514 is hinged to the first hinge seat 5642, and the third hinge 515 is hinged to the third hinge seat 5662. The first damping swing member 511 is located within the second slide groove 216 and can slide and rotate within the second slide groove 216.

[0135] The second damping swing arm 52 is mounted on the second rotating rod 562 and is slidably and rotatably connected to the second fixed plate 22. The second damping shaft seat 522 and the fourth damping shaft seat 523 are sleeved around the outer periphery of the second rotating rod 562 and are fixedly connected to the second rotating rod 562. The second hinge 565 and the portion of the fixing sleeve 563 connected to the second hinge 565 are located within the second receiving notch 526. The second hinge body 524 is hinged to the second hinge seat 5652, and the fourth hinge body 525 is hinged to the fourth hinge seat 5672. The second damping swing body 521 is located within the fourth slide groove 226 and can slide and rotate within the fourth slide groove 226.

[0136] The first damping member 54 is mounted within the first fixing plate 21. The first damping member 54 is mounted within the first receiving groove 217, and the end of the first elastic body 541 facing away from the first abutting block 544 is fixedly connected to the inner wall of the first receiving groove 217. The first abutting end 5431 abuts the first side surface 5111. The elastic extension direction of the first elastic body 541 is parallel to the length direction of the fixing base 10 and the length direction of the first fixing plate 21. In other words, the elastic extension direction of the first elastic body 541 is parallel to the Y direction.

[0137] The second damping member 55 is mounted within the second fixing plate 22. The second damping member 55 is mounted within the second receiving groove 227, and the end of the second elastic body 551 facing away from the second abutting block 554 is fixedly connected to the inner wall of the second receiving groove 227. The second abutting end 5531 abuts the second side surface 5211. The elastic extension direction of the second elastic body 551 is parallel to the Y direction.

[0138] When the first fixed plate 21 rotates, it drives the first damping swing arm 51 to rotate, and causes the first damping oscillating body 511 of the first damping swing arm 51 to slide and rotate within the second slide groove 216. When the first damping swing arm 51 rotates, it drives the first rotating rod 561 to rotate synchronously, thereby driving the first gear 531 to rotate. When the first gear 531 rotates, it drives the intermediate gear 533 to rotate, thereby driving the second gear 532 to rotate. When the second gear 532 rotates, it drives the second rotating rod 562 to rotate, thereby driving the second damping swing arm 52 to rotate, and the second fixed plate 22 to rotate, while causing the second damping oscillating body 521 to slide and rotate within the fourth slide groove 226, thereby achieving synchronous rotation of the first damping swing arm 51 and the second damping swing arm 52, as well as synchronous rotation of the first fixed plate 21 and the second fixed plate 22.

[0139] The first damping arm 51 and the second damping arm 52 rotate in opposite directions. For example, when the rotating mechanism 100 switches from the flattened state to the folded state, the first fixed plate 21, the first damping arm 51, and the first rotating rod 561 rotate clockwise, while the second fixed plate 22, the second damping arm 52, and the second rotating rod 562 rotate counterclockwise. When the rotating mechanism 100 switches from the folded state to the flattened state, the first fixed plate 21, the first damping arm 51, and the first rotating rod 561 rotate counterclockwise, while the second fixed plate 22, the second damping arm 52, and the second rotating rod 562 rotate clockwise.

[0140] In this embodiment, by configuring the first rotating rod 561 as a flat shaft and providing a rotating hole in the first damping swing arm 51 that mates with the first rotating rod 561, a fixed connection between the first damping swing arm 51 and the first rotating rod 561 can be achieved without requiring additional fixing components, thereby simplifying the structure of the rotating mechanism 100. Furthermore, configuring the second rotating rod 562 as a flat shaft allows a fixed connection between the second damping swing arm 52 and the second rotating rod 562, further simplifying the structure of the rotating mechanism 100.

[0141] It should be noted that when the first damping swing arm 51 rotates, it drives the first hinge 514 and the third hinge 515 to rotate synchronously. When the first hinge 514 rotates, the protrusion of the first hinge 514 rotates from the recess of the first hinge seat 5642 to the protrusion of the first hinge seat 5642, and then rotates from the protrusion of the first hinge seat 5642 to the recess of the first hinge seat 5642. This repeatedly pushes the first hinge seat 5642 to slide along the first rotating rod 561, thereby compressing the first elastic member 5641 and generating an elastic force. The elastic restoring force of the first elastic member 5641 acts on the first hinge seat 5642, causing it to squeeze the first hinge 514, thereby providing a damping force for the rotation of the first hinge 514, and thus providing a damping force for the rotation of the first damping swing arm 51. At the same time, when the third hinge 515 rotates, the protrusion of the third hinge 515 rotates out of the recess of the third hinge seat 5662 to the protrusion of the third hinge seat 5662, and then rotates from the protrusion of the third hinge seat 5662 into the recess of the third hinge seat 5662, thereby repeatedly pushing the third hinge seat 5662 to slide along the first rotating rod 561, thereby compressing the third elastic member 5661, causing the third elastic member 5661 to generate an elastic force. The elastic restoring force of the third elastic member 5661 acts on the third hinge seat 5662, causing the third hinge seat 5662 to squeeze the third hinge 515, thereby providing a damping force for the rotation of the third hinge 515, and further providing a damping force for the rotation of the first damping swing arm 51. That is to say, when the first damping swing arm 51 rotates, the first elastic member 5641 and the third elastic member 5661 are squeezed to generate an elastic force. The elastic restoring force generated by the elastic force acts on the first damping swing arm 51, providing a damping force for the rotation of the first damping swing arm 51. The damping force of the first damping swing arm 51 acts on the first shell 210 through the first fixed plate 21, thereby providing a damping feel to the user.

[0142] When the second damping swinging member 521 rotates, it drives the second hinge 524 and the fourth hinge 525 to rotate synchronously. When the second hinge 524 rotates, the protrusion of the second hinge 524 rotates from the recess of the second hinge seat 5652 to the protrusion of the second hinge seat 5652, and then rotates from the protrusion of the second hinge seat 5652 to the recess of the second hinge seat 5652. This repeatedly pushes the second hinge seat 5652 to slide along the second rotating rod 562, thereby compressing the second elastic member 5651 and generating an elastic force. The elastic restoring force of the second elastic member 5651 acts on the second hinge seat 5652, causing it to squeeze the second hinge 524, thereby providing a damping force for the rotation of the second hinge 524, and thus providing a damping force for the rotation of the second damping swing arm 52. When the fourth hinge 525 rotates, the protrusion of the fourth hinge 525 rotates out of the recess of the fourth hinge seat 5672 to the protrusion of the fourth hinge seat 5672, and then rotates from the protrusion of the fourth hinge seat 5672 into the recess of the fourth hinge seat 5672, thereby repeatedly pushing the fourth hinge seat 5672 to slide along the second rotating rod 562, thereby compressing the fourth elastic member 5671, causing the fourth elastic member 5671 to generate an elastic force. The elastic restoring force of the fourth elastic member 5671 acts on the fourth hinge seat 5672, causing the fourth hinge seat 5672 to squeeze the fourth hinge 525, thereby providing a damping force for the rotation of the fourth hinge 525, and further providing a damping force for the rotation of the second damping swing arm 52. That is to say, when the second damping swing arm 52 rotates, the second elastic member 5651 and the fourth elastic member 5671 are squeezed to generate an elastic force. The elastic restoring force generated by the elastic force acts on the second damping swing arm 52, providing a damping force for the rotation of the second damping swing arm 52. The damping force of the second damping swing arm 52 acts on the second shell 220 through the second fixed plate 22, thereby providing a damping feel to the user.

[0143] Furthermore, when the first fixed plate 21 rotates, the first damping swing body 511 slides within the second slide groove 216, causing the first damping member 54 to move relative to the first damping swing arm 51. The first side surface 5111 moves relative to the first abutting end 5431 and constantly abuts against the first abutting end 5431, causing the first abutting block 544 to compress the first elastic body 541, placing the first elastic body 541 in a compressed state. When the first elastic body 541 is in a compressed state, it exerts an elastic restoring force, which causes the first abutting end 5431 to abut against the first side surface 5111, generating a force that prevents the first damping swing arm 51 from rotating. This provides a damping force for the first damping swing arm 51, thereby providing a damping feel for the user. In addition, the first damping member 54 provides a damping force for the rotation of the first damping swing arm 51, which can make the first damping swing arm 51 hover at a preset angle, so that the first damping swing arm 51 drives the first fixed plate 21 to hover, thereby driving the first shell 210 to hover, thereby improving the user experience.

[0144] When the elastic restoring force of the first elastic body 541 causes the first abutting end 5431 to abut the first side surface 5111, the abutting force of the first damping member 54 on the first damping swing arm 51 increases the friction between the first abutting end 5431 and the first side surface 5111, thereby preventing the first damping member 54 from sliding relative to the first damping swing member 511. In other words, it prevents the first fixed plate 21 from sliding relative to the first damping swing arm 51, thereby preventing the first fixed plate 21 from causing the first damping swing arm 51 to rotate relative to the fixed base. Furthermore, the abutting force of the first damping member 54 on the first damping swing arm 51 causes the first damping swing member 511 to abut the inner wall of the second slot 216, thereby increasing the friction between the first damping swing member 511 and the first fixed plate 21, thereby preventing the first damping swing member 511 from sliding relative to the first fixed plate 21, thereby preventing the first fixed plate 21 from causing the first damping swing arm 51 to rotate relative to the fixed base 10. At the same time, the supporting force of the first damping member 54 on the first damping swing arm 51 also causes the first hinge body 514 to resist the first hinge seat 5642, and the third hinge body 515 to resist the third hinge seat 5662, so as to prevent the first hinge body 514 from rotating relative to the first hinge seat 5642 and the third hinge body 515 from rotating relative to the third hinge seat 5662, thereby preventing the first damping swing arm 51 from rotating relative to the fixed base 10, thereby improving the damping feel of the rotating mechanism 100, and enabling the first damping swing arm 51 to drive the first fixed plate 21 to hover at a preset angle, so as to realize the hovering of the rotating mechanism 100 and the foldable electronic device 500.

[0145] When the second fixed plate 22 rotates, the second damping swing body 521 slides within the second slide groove 216, causing the second damping member 55 to move relative to the second damping swing arm 52. The second side surface 5211 moves relative to the second abutting end 5531 and constantly abuts against the second abutting end 5531, causing the second abutting block 554 to compress the second elastic body 551, placing the second elastic body 551 in a compressed state. When the second elastic body 551 is in a compressed state, it exerts an elastic restoring force, which causes the second abutting end 5531 to abut against the second side surface 5211, generating a force that prevents the second damping swing arm 52 from rotating. This provides a damping force for the rotation of the second damping swing arm 52, thereby providing a damping feel for the user. In addition, the second damping member 55 provides a damping force for the rotation of the second damping swing arm 52, which can enable the second damping swing arm 52 to hover at a preset angle, so that the second damping swing arm 52 drives the second fixed plate 22 to hover, thereby driving the second shell 220 to hover, and then enabling the foldable electronic device 500 to hover at any angle, so as to enhance the user experience.

[0146] When the elastic restoring force of the second elastic body 551 causes the second abutting end 5531 to abut the second side surface 5211, the abutting force of the second damping member 55 on the second damping swing arm 52 increases the friction between the second abutting end 5531 and the second side surface 5211, thereby preventing the second damping member 55 from sliding relative to the second damping swing member 521. This, in turn, prevents the second fixed plate 22 from sliding relative to the second damping swing arm 52, thereby preventing the second fixed plate 22 from causing the second damping swing arm 52 to rotate relative to the fixed base. Furthermore, the abutting force of the second damping member 55 on the second damping swing arm 52 causes the second damping swing member 521 to abut the inner wall of the fourth slot 226, thereby increasing the friction between the second damping swing member 521 and the second fixed plate 22, thereby preventing the second damping swing member 521 from sliding relative to the second fixed plate 22, thereby preventing the second fixed plate 22 from causing the second damping swing arm 52 to rotate relative to the fixed base 10. At the same time, the supporting force of the second damping member 55 on the second damping swing arm 52 also causes the second hinge body 524 to resist the second hinge seat 5652, and the fourth hinge body 525 to resist the fourth hinge seat 5672, so as to prevent the second hinge body 524 from rotating relative to the second hinge seat 5652 and the fourth hinge body 525 from rotating relative to the fourth hinge seat 5672, thereby preventing the second damping swing arm 52 from rotating relative to the fixed base 10, thereby further improving the damping feel of the rotating mechanism 100, and enabling the second damping swing arm 52 to drive the second fixed plate 22 to hover at a preset angle, so as to realize the hovering of the rotating mechanism 100 and the foldable electronic device 500.

[0147] In this embodiment, the elastic force of the first elastic body 541 can be adjusted by adjusting the distance between the first damping member 54 and the first damping swing arm 51, thereby adjusting the magnitude of the damping force provided by the first damping member 54 on the first damping swing arm 51. For example, by installing the first damping member 54 closer to the first damping swing arm 51 in the Y direction, the compression of the first elastic body 541 can be increased, thereby increasing the elastic force of the first elastic body 541 and, in turn, increasing the damping force applied by the first damping member 54 on the first damping swing arm 51. Alternatively, by installing the first damping member 54 further away from the first damping swing arm 51 in the Y direction, the compression of the first elastic body 541 can be reduced, thereby reducing the elastic force of the first elastic body 541 and, in turn, reducing the damping force applied by the first damping member 54 on the first damping swing arm 51. Alternatively, by using first elastic bodies 541 with different elastic forces, the magnitude of the damping force provided by the first damping member 54 on the first damping swing arm 51 can be varied.

[0148] Furthermore, in this embodiment, the distance between the second damping member 55 and the second damping swing arm 52 can be adjusted to adjust the elastic force of the second elastic body 551, thereby adjusting the magnitude of the damping force provided by the second damping member 55 on the second damping swing arm 52. For example, by installing the second damping member 55 closer to the second damping swing arm 52 in the Y direction, the damping force applied by the second damping member 55 on the second damping swing arm 52 can be increased. Alternatively, by installing the second damping member 55 farther from the second damping swing arm 52 in the Y direction, the damping force applied by the second damping member 55 on the second damping swing arm 52 can be reduced. Alternatively, by using second elastic bodies 551 with different elastic forces, the magnitude of the damping force provided by the second damping member 55 on the second damping swing arm 52 can be varied.

[0149] Please continue reading Figure 14 and Figure 15 When the rotating mechanism 100 is in the flattened state, the first damping swing arm 51 and the second damping swing arm 52 are flattened relative to the fixed base 10. The first abutting end 5431 of the first damping member 54 abuts the first side surface 5111, and the second abutting end 5531 of the second damping member 55 abuts the second side surface 5211. The first elastic member 541 and the second elastic member 551 are in a compressed state. The first hinge 514 engages with the first hinge seat 5642, the third hinge 515 engages with the third hinge seat 5662; the second hinge 524 engages with the second hinge seat 5652, and the fourth hinge 525 engages with the fourth hinge seat 5672. The first elastic member 5641, the third elastic member 5661, the second elastic member 5651, and the fourth elastic member 5671 are all in a pre-compressed state. The "pre-compressed state" here can refer to either a compressed state or a natural state. The "pre-compressed state" below will be interpreted similarly. Here, the phrase "engagement" between a hinge and its seat means that the protrusion of the hinge is located within the corresponding recess of the seat, and the protrusion of the seat is located within the corresponding recess of the hinge. For example, "engagement between the first hinge 514 and the first seat 5642" means that the protrusion of the first hinge 514 is located within the recess of the first seat 5642, and the protrusion of the first seat 5642 is located within the recess of the first hinge 514. The same shall apply hereinafter.

[0150] Please also refer to Figure 16 , Figure 16 yes Figure 15 The diagram shows a partial structure of the rotating mechanism 100 in a first intermediate state.

[0151] As the rotating mechanism 100 rotates from the flattened state to the first intermediate state, the first fixed plate 21 rotates clockwise, driving the first damping swing arm 51 to rotate clockwise, thereby driving the first hinge 514 and the third hinge 515 to rotate clockwise. As the first hinge 514 rotates, the protrusion of the first hinge 514 pivots out of the recess of the first hinge seat 5642 and abuts against the first hinge seat 5642, causing the first hinge seat 5642 to compress the first elastic member 5641 and generate an elastic force. The elastic restoring force of the first elastic member 5641 acts on the first hinge seat 5642, causing it to abut against the first hinge 514, preventing the first hinge 514 from rotating, thereby providing a damping force for the rotation of the first damping swing arm 51. When the third hinge 515 rotates, the protrusion of the third hinge 515 rotates out of the recess of the third hinge seat 5662 and abuts the third hinge seat 5662, causing the third hinge seat 5662 to compress the third elastic member 5661, causing the third elastic member 5661 to generate an elastic force, providing a damping force for the rotation of the first damping swing arm 51. Simultaneously, when the first fixed plate 21 drives the first damping swing arm 51 to rotate, the first damping swing arm 51 also slides within the second slide groove 216 of the first fixed plate 21. The first abutting end 5431 moves relative to the first side surface 5111 and always abuts the first side surface 5111. The first elastic body 541 is always in a compressed state, causing the first abutting end 5431 to always abut the first side surface 5111, thereby providing a damping force for the rotation of the first damping swing arm 51 and achieving the suspension of the first damping swing arm 51 and the first fixed plate 21.

[0152] Furthermore, when the first damping swing arm 51 rotates clockwise, it drives the first rotating rod 561 to rotate clockwise, thereby driving the second rotating rod 562 to rotate counterclockwise via the synchronous gear 53. This in turn drives the second hinge 524 and the fourth hinge 525 to rotate counterclockwise, driving the second damping swing arm 52 to rotate counterclockwise, thereby driving the second fixing plate 22 to rotate counterclockwise. When the second hinge 524 rotates, the protrusion of the second hinge 524 rotates out of the recess of the second hinge seat 5652 and abuts the second hinge seat 5652, causing the second hinge seat 5652 to compress the second elastic member 5651, generating an elastic force. The elastic restoring force of the second elastic member 5651 acts on the second hinge seat 5652, causing it to abut the second hinge 524, preventing the second hinge 524 from rotating, thereby providing a damping force for the rotation of the second damping swing arm 52. When the fourth hinge 525 rotates, the protrusion of the fourth hinge 525 rotates out of the recess of the fourth hinge seat 5672 and abuts the fourth hinge seat 5672, causing the fourth hinge seat 5672 to compress the fourth elastic member 5671, generating an elastic force that provides a damping force for the rotation of the second damping swing arm 52. Simultaneously, as the second damping swing arm 52 drives the second fixed plate 22 to rotate, the second damping swing arm 52 also slides within the fourth guide groove 226 of the second fixed plate 22. The second abutting end 5531 moves relative to the second side surface 5211 and constantly abuts the second side surface 5211. The second elastic member 551 is always in a compressed state, causing the second abutting end 5531 to constantly abut the second side surface 5211, providing a damping force for the rotation of the second damping swing arm 52 and achieving a hovering of the second damping swing arm 52 and the second fixed plate 22.

[0153] like Figure 16 As shown, when the rotating mechanism 100 rotates to the first intermediate state, the protrusion of the first hinge body 514 and the protrusion of the first hinge seat 5642 are aligned and abut against each other, and the protrusion of the third hinge body 515 and the protrusion of the third hinge seat 5662 are aligned and abut against each other. The first elastic member 5641 and the third elastic member 5661 are both in a compressed state and have reached maximum compression. The protrusion of the second hinge body 524 and the protrusion of the second hinge seat 5652 are aligned and abut against each other, and the protrusion of the fourth hinge body 525 and the protrusion of the fourth hinge seat 5672 are aligned and abut against each other. The second elastic member 5651 and the fourth elastic member 5671 are both in a compressed state and have reached maximum compression. At this time, the elastic forces of the first elastic member 5641 , the second elastic member 5651 , the third elastic member 5661 and the fourth elastic member 5671 all reach their maximum values, and the third damping member 56 provides the maximum damping force for the first damping swing arm 51 and the second damping swing arm 52 .

[0154] The first fixing plate 21 and the second fixing plate 22 are Figure 16On the basis of the above, the first and second damping swing arms 51, 52 continue to rotate toward each other, driving the first and second damping swing arms 51, 52 to continue rotating toward each other, causing the rotating mechanism 100 to rotate to the second intermediate state (not shown). The first fixed plate 21 continues to rotate clockwise, driving the first damping swing arm 51 to continue rotating clockwise, thereby driving the second damping swing arm 52 to continue rotating counterclockwise, and further driving the second fixed plate 22 to continue rotating counterclockwise. At this time, the first hinge 514 and the third hinge 515 continue to rotate clockwise. The protrusion of the first hinge 514 slides into the recess of the first hinge seat 5642 and engages with the first hinge seat 5642. The protrusion of the third hinge 515 slides into the recess of the third hinge seat 5662 and engages with the third hinge seat 5662. The first elastic member 5641 and the third elastic member 5661 elastically recover and return to the pre-compressed state. At the same time, during the rotation of the first fixed plate 21 and the first damping swing arm 51, the first abutting end 5431 of the first damping member 54 abuts against the first side surface 5111, providing damping force for the rotation of the first damping swing arm 51 and the first fixed plate 21, and realizing the suspension of the first fixed plate 21 and the first damping swing arm 51 during the rotation process.

[0155] The second hinge 524 and the fourth hinge 525 continue to rotate clockwise, and the protrusion of the second hinge 524 slides into the recess of the second hinge seat 5652 and engages with the second hinge seat 5652. The protrusion of the fourth hinge 525 slides into the recess of the fourth hinge seat 5672 and engages with the fourth hinge seat 5672. The second elastic member 5651 and the fourth elastic member 5671 elastically recover and return to the pre-compressed state, allowing the rotating mechanism 100 to rotate to the second intermediate state. At the same time, during the rotation of the second fixed plate 22 and the second damping swing arm 52, the second abutting end 5531 of the second damping member 55 abuts the second side surface 5211, providing a damping force for the rotation of the second damping swing arm 52 and the second fixed plate 22, and achieving a hovering of the second fixed plate 22 and the second damping swing arm 52 during the rotation.

[0156] Please also refer to Figure 17 , Figure 17 yes Figure 15 The diagram shows a partial structure of the rotating mechanism 100 in a folded state.

[0157] After the rotating mechanism 100 rotates to the second intermediate state, the first fixed plate 21 and the second fixed plate 22 continue to rotate toward each other, driving the first damping swing arm 51 and the second damping swing arm 52 to rotate toward each other, thereby rotating the rotating mechanism 100 to the folded state. As the first fixed plate 21 continues to rotate clockwise, it drives the first damping swing arm 51 to continue rotating clockwise. The first hinge 514 and the third hinge 515 continue to rotate clockwise. The protrusion of the first hinge 514 first rotates to face the protrusion of the first hinge seat 5642, then slides into the recess of the first hinge seat 5642, engaging with the first hinge seat 5642. The first elastic member 5641 is first compressed and then elastically recovers. The protrusion of the third hinge body 515 first rotates until it faces the protrusion of the third hinge seat 5662, then slides into the recess of the third hinge seat 5662, engaging with the third hinge seat 5662. The third elastic member 5661 is first compressed and then elastically recovers. Simultaneously, during the rotation of the first fixed plate 21 and the first damping swing arm 51, the first abutting end 5431 of the first damping member 54 abuts the first side surface 5111, providing a damping force for the rotation of the first damping swing arm 51 and the first fixed plate 21, and ensuring that the first fixed plate 21 and the first damping swing arm 51 are suspended during the rotation.

[0158] When the first damping swing arm 51 rotates clockwise, it drives the second damping swing arm 52 to rotate counterclockwise, thereby driving the second fixed plate 22 to rotate counterclockwise. When the second damping swing arm 52 rotates counterclockwise, the second hinge body 524 and the fourth hinge body 525 rotate counterclockwise, and the protrusion of the second hinge body 524 first rotates to be opposite to the protrusion of the second hinge seat 5652, and then slides into the recess of the second hinge seat 5652, and engages with the second hinge seat 5652. The second elastic member 5651 is first compressed and then elastically recovers. The protrusion of the fourth hinge body 525 first rotates to be opposite to the protrusion of the fourth hinge seat 5672, and then slides into the recess of the fourth hinge seat 5672, and engages with the fourth hinge seat 5672. The fourth elastic member 5671 is first compressed and then elastically recovers, so that the rotating mechanism 100 is in a folded state (such as Figure 17 Meanwhile, during the rotation process, the second fixing plate 22 and the second damping swing arm 52 rotate, and the second abutting end 5531 of the second damping member 55 abuts against the second side surface 5211, providing a damping force for the rotation of the second damping swing arm 52 and the second fixing plate 22, thereby achieving the hovering of the second fixing plate 22 during the rotation process.

[0159] When the rotating mechanism 100 is in the folded state, the first damping swing arm 51 and the second damping swing arm 52 are folded relative to each other. The first hinge 514 engages with the first hinge seat 5642, the third hinge 515 engages with the third hinge seat 5662, the second hinge 524 engages with the second hinge seat 5652, and the fourth hinge 525 engages with the fourth hinge seat 5672. The first elastic member 5641, the third elastic member 5661, the second elastic member 5651, and the fourth elastic member 5671 are all in a pre-compressed state. The first damping member 54 abuts the first damping swing arm 51, and the second damping member 55 abuts the second damping swing arm 52.

[0160] In this embodiment, the first damping member 54 is provided. During the rotation of the first fixed plate 21 and the first damping arm 51, the first damping member 54 always abuts the first damping arm 51, generating a force that prevents the first damping arm 51 from rotating. This provides a damping force for the rotation of the first damping arm 51, the first fixed plate 21, and the first housing 210, thereby providing a damping feel for the user. Furthermore, the damping force provided by the first damping member 54 for the rotation of the first damping arm 51 enables the first damping arm 51 to hover at a preset angle, thereby causing the first damping arm 51 to cause the first fixed plate 21 to hover, and thus causing the first housing 210 to hover, thereby improving the user experience.

[0161] Furthermore, this embodiment also includes a second damping member 55. During the rotation of the second fixing plate 22 and the second damping arm 52, the second damping member 55 always abuts against the second damping arm 52, generating a force that prevents the second damping arm 52 from rotating. This provides a damping force for the rotation of the second damping arm 52, the second fixing plate 22, and the second housing 220, thereby providing a damping feel for the user. Furthermore, the damping force provided by the second damping member 55 for the rotation of the second damping arm 52 enables the second damping arm 52 to hover at a preset angle, thereby causing the second damping arm 52 to hover, and thus causing the second housing 220 to hover, thereby enabling the foldable electronic device 500 to hover at any angle, thereby enhancing the user experience.

[0162] At the same time, this embodiment also provides a third damping member 56, which generates a force to prevent the first damping swing arm 51 and the second damping swing arm 52 from rotating. This provides a damping force for the rotation of the first damping swing arm 51, the first fixing plate 21, and the first housing 210, as well as the second damping swing arm 52, the second fixing plate 22, and the second housing 220, thereby providing the user with a damping feel, further enhancing the user's experience. Furthermore, during the rotation of the rotating mechanism 100, the damping force provided by the third damping member 56 continuously changes. When the rotating mechanism 100 rotates to the folded state and the flattened state, the first damping swing arm 51 and the second damping swing arm 52 both engage with the third damping member 56, and the damping force provided by the third damping member 56 is minimized. The user can sense the change in damping force, thereby providing the user with a locked feeling when the device is flattened and folded.

[0163] See also Figure 11 and Figure 18 , Figure 18 yes Figure 17 A cross-sectional view of the rotating mechanism 100 is shown.

[0164] The first damping assembly 50 also includes a damping plate 57. The damping plate 57 is mounted on the first rotating rod 561 and the second rotating rod 562, and is spaced apart from the first hinge 564 and the second hinge 565. In this embodiment, there are multiple damping plates 57. Multiple damping plates 57 are located on opposite sides of the synchronous gear 53 in the Y direction and are arranged in sequence along the Y direction. When the first damping swing arm 51 and the second damping swing arm 52 rotate relative to the fixed base 10, they drive the first rotating rod 561 and the second rotating rod 562 to rotate, so that a damping force is generated between the first rotating rod 561 and the second rotating rod 562 and the damping plate 57. The damping force can prevent the first damping swing arm 51 and the second damping swing arm 52 from rotating, so that the user can clearly feel the damping force generated by the damping plate 57, further improving the damping feel and enhancing the user's usage experience.

[0165] See also Figure 19 , Figure 19 yes Figure 6 FIG. 1 is a schematic diagram of the exploded structure of the pressure plate assembly 60 in the rotating mechanism 100 .

[0166] The pressure plate assembly 60 includes a first pressure plate 61, a second pressure plate 62, a first pressure plate swing arm 63, and a second pressure plate swing arm 64. The first pressure plate 61 is rotatably and slidably connected to the first fixed plate 21 of the first rotating assembly 101, the first fixed plate 21A of the second rotating assembly 101A, and the first fixed plate 21B of the third rotating assembly 101B. The second pressure plate 62 is rotatably and slidably connected to the second fixed plate 22 of the first rotating assembly 101, the second fixed plate 22A of the second rotating assembly 101A, and the second fixed plate 22B of the third rotating assembly 101B. The first pressure plate swing arm 63 is slidably connected to the first pressure plate 61 and is rotatably connected to the fixed base 10. The second pressure plate swing arm 64 is slidably connected to the second pressure plate 62 and is rotatably connected to the fixed base 10.

[0167] The first pressure plate 61 includes a first body 611 and a first slider 612. The first body 611 is rectangular. The first body 611 includes a first side portion 6111 and a second side portion 6112, which are arranged opposite to each other, and the first side portion 6111 and the second side portion 6112 are respectively located on opposite sides of the first body 611 in the X direction. The first body 611 is provided with a first pressure plate chute 613, which passes through the first body 611 in the width direction of the first body 611. In some other embodiments, the first pressure plate chute 613 may not pass through the second side portion 6112. In this embodiment, there are four first pressure plate chute 613, and the four first pressure plate chute 613 are arranged in sequence along the Y direction. In other embodiments, the first pressure plate chute 613 may also be one, two, three or more.

[0168] The first slider 612 is provided on the bottom surface of the first body 611 and is fixedly connected to the first body 611. In this embodiment, there are six first sliders 612, and the six first sliders 612 are arranged in sequence along the Y direction. Each first slider 612 extends in an arc shape from the bottom surface of the first body 611 toward a direction away from the top surface. The structure of the first slider 612 is compatible with the structure of the first guide groove 214. Among them, the two first sliders 612 located on the positive side of the Y axis correspond to the position of the first guide groove 214 of the first fixed plate 21 in the first rotating assembly 101, the two first sliders 612 located on the negative side of the Y axis correspond to the position of the first guide groove of the first fixed plate 21A in the second rotating assembly 101A, and the two first sliders 612 located in the middle of the first body 611 correspond to the position of the first guide groove of the first fixed plate 21B in the third rotating assembly 101B.

[0169] The structure of the second pressure plate 62 is roughly the same as that of the first pressure plate 61. The second pressure plate 62 includes a second body 621 and a second slider 622. The second body 621 includes a third side portion 6211 and a fourth side portion 6212. The second body 621 is provided with second pressure plate chutes 623. There are four second pressure plate chutes 623.

[0170] The first pressure plate swing arm 63 includes a first shaft seat 632 and a first pressure plate swing body 631, and the first shaft seat 632 is fixedly connected to the first pressure plate swing body 631. The axis extension direction of the first shaft seat 632 is parallel to the Y direction. In this embodiment, there are four first pressure plate swing arms 63. In other embodiments, there are one, two, three or more first pressure plate swing arms 63. The structure of the second pressure plate swing arm 64 is the same as or similar to that of the first pressure plate swing arm 63. The second pressure plate swing arm 64 includes a second shaft seat 642 and a second pressure plate swing body 641, and the second shaft seat 642 is fixedly connected to the second pressure plate swing body 641. The axis extension direction of the second shaft seat 642 is parallel to the Y direction. In this embodiment, there are four second pressure plate swing arms 64. In other embodiments, there are one, two, three or more second pressure plate swing arms 64.

[0171] In order to better understand the assembly relationship between the pressure plate assembly 60 and other components, please refer to Figure 5 and Figure 6The first pressure plate 61 and the first pressure plate swing arm 63 are located on the same side of the fixed base 10 in the X direction, and the first pressure plate swing arms 63 are spaced apart along the Y direction. The first shaft seat 632 of the first pressure plate swing arm 63 is rotatably connected to the first connecting shaft 125 of the fixed base 10, and the first shaft seat 632 can rotate around the first connecting shaft 125 to ensure the rotational connection between the first pressure plate swing arm 63 and the fixed base 10. One end of a first pressure plate swing body 631 facing away from the first shaft seat 632 is installed in a first pressure plate slide groove 613, and each first pressure plate swing body 631 can slide in the corresponding first pressure plate slide groove 613. The first pressure plate 61 is slidably and rotatably connected to the first fixed plate 21 of the first rotating assembly 101, the first fixed plate 21A of the second rotating assembly 101A, and the first fixed plate 21B of the third rotating assembly 101B. Among them, the two first sliders 612 located on the positive side of the Y-axis of the first pressure plate 61 are installed in the first guide groove 214 of the first rotating component 101, the two first sliders 612 located on the negative side of the Y-axis are installed in the first guide groove of the second rotating component 101A, and the two first sliders 612 located in the middle of the first body 611 are installed in the first guide groove of the third rotating component 101B, and each first slider 612 can slide in the corresponding first guide groove.

[0172] When the first housing 210 rotates, it drives the first fixed plate 21 in the first rotating assembly 101, the first fixed plate 21A in the second rotating assembly 101A, and the first fixed plate 21B in the third rotating assembly 101B to rotate simultaneously relative to the fixed base 10, thereby driving the first pressure plate 61 to rotate relative to the fixed base 10 and causing the first slider 612 to slide in an arc within the corresponding first guide groove 214, thereby driving the first pressure plate 61 to slide in an arc relative to the first fixed plate 21. Furthermore, when the first pressure plate 61 rotates, it drives the first pressure plate swinging member 631 to rotate, thereby driving the first shaft seat 632 to rotate relative to the fixed base 10, thereby achieving rotation of the first pressure plate 61 and the first pressure plate swinging arm 63 relative to the fixed base 10.

[0173] The second pressure plate 62 and the second pressure plate swing arm 64 are located on the other side of the fixed base 10 in the X direction, and the second pressure plate swing arms 64 are spaced apart along the Y direction. The second shaft seat 642 of the second pressure plate swing arm 64 is rotatably connected to the second connecting shaft 126 of the fixed base 10. The second shaft seat 642 can rotate about the second connecting shaft 126 to ensure the rotational connection between the second pressure plate swing arm 64 and the fixed base 10. The end of each second pressure plate swing member 641 facing away from the second shaft seat 642 is mounted in a second pressure plate slot 623, and each second pressure plate swing member 641 can slide in the corresponding second pressure plate slot 623. The second pressure plate 62 is slidably and rotatably connected to the second fixed plate 22 of the first rotating assembly 101, the second fixed plate 22A of the second rotating assembly 101A, and the second fixed plate 22B of the third rotating assembly 101B. Among them, the two second sliders 622 located on the positive side of the Y-axis of the second pressure plate 62 are installed in the second guide groove 224 of the first rotating component 101, the two second sliders 622 located on the negative side of the Y-axis are installed in the second guide groove in the second rotating component 101A, and the two second sliders 622 located in the middle of the second body 621 are installed in the second guide groove in the third rotating component 101B, and each second slider 622 can slide in the corresponding second guide groove 224.

[0174] When the second housing 220 rotates, it drives the second fixed plate 22 in the first rotating assembly 101, the second fixed plate 22A in the second rotating assembly 101A, and the second fixed plate 22B in the third rotating assembly 101B to rotate simultaneously relative to the fixed base 10, thereby driving the second pressure plate 62 to rotate relative to the fixed base 10 and causing the second slider 622 to slide in an arc within the corresponding second guide groove 224, thereby driving the second pressure plate 62 to slide in an arc relative to the second fixed plate 22. Furthermore, when the second pressure plate 62 rotates, it drives the second pressure plate swinging body 641 to rotate, thereby driving the second shaft seat 642 to rotate relative to the fixed base 10, thereby achieving rotation of the second pressure plate 62 and the second pressure plate swing arm 64 relative to the fixed base 10.

[0175] The first pressing plate 61 and the second pressing plate 62 are both disposed opposite the display screen 300. That is, the orthographic projections of the display screen 300 on the first pressing plate 61 and the second pressing plate 62 completely cover the first pressing plate 61 and the second pressing plate 62, or partially cover the first pressing plate 61 and the second pressing plate 62. The first pressing plate 61 and the second pressing plate 62 jointly support the display screen 300, thereby increasing the stability of the connection of the display screen 300 and ensuring a good display on the display screen 300.

[0176] In this embodiment, the first housing 210 drives the first fixing plate 21 to rotate, thereby driving the first pressure plate 61 to rotate. The second housing 220 drives the second fixing plate 22 to rotate, thereby driving the second pressure plate 62 to rotate, thereby switching the foldable electronic device 500 between a folded and an unfolded state, thereby achieving folding and unfolding of the display screen 300. Furthermore, by providing a first slider 612 on the first pressure plate 61 and a first guide groove 214 on the first fixing plate 21 that cooperates with the first slider 612, the first pressure plate 61 can slide in an arc relative to the first fixing plate 21. By providing a second slider 622 on the second pressure plate 62 and a second guide groove 224 on the second fixing plate 22 that cooperates with the second slider 622, the second pressure plate 62 can slide in an arc relative to the second fixing plate 22.

[0177] When the first fixing plate 21 and the second fixing plate 22 rotate, the first pressing plate 61 and the second pressing plate 62 rotate relative to each other, and the first pressing plate 61 slides in an arc relative to the first fixing plate 21, while the second pressing plate 62 slides in an arc relative to the second fixing plate 22. This allows the angle between the first pressing plate 61 and the second pressing plate 62 to be adjusted, thereby adapting to the folding angle of the foldable portion 330 of the display screen 300. This prevents the first pressing plate 61 and the second pressing plate 62 from squeezing the display screen 300 when the rotating mechanism 100 is in the folded state. In other words, when the rotating mechanism 100 is in the folded state, the angle between the first fixing plate 21 and the second fixing plate 22 is different from the angle between the first pressing plate 61 and the second pressing plate 62. Moreover, the angle between the first pressing plate 61 and the second pressing plate 62 can be adjusted according to the bending angle of the display screen 300 to adapt to the bending of the display screen 300.

[0178] In this embodiment, a first pressure plate swing arm 63 is provided, and the first pressure plate 61 drives the first pressure plate swing arm 63 to rotate, thereby enabling the first pressure plate 61 to rotate relative to the fixed base 10, thereby improving the rotation stability of the first pressure plate 61. A second pressure plate swing arm 64 is provided, and the second pressure plate 62 drives the second pressure plate swing arm 64 to rotate, thereby enabling the second pressure plate 62 to rotate relative to the fixed base 10, thereby improving the rotation stability of the second pressure plate 62.

[0179] See also Figure 20 , Figure 20 yes Figure 5 A cross-sectional view of the rotating mechanism 100 is shown.

[0180] The floating plate 70 is a flat plate-shaped structure. It is mounted on the fixed base 10 and faces the upper housing 12 in the Z direction. A fifth elastic member 71 is disposed within the fixed base 10. The fifth elastic member 71 is located within the fixed base 10, with one end fixedly connected to the fixed base 10 and the other end fixedly connected to the floating plate 70. The elastic extension direction of the fifth elastic member 71 is parallel to the Z direction.

[0181] When the rotating mechanism 100 is in the flattened position, the first and second pressure plate swing arms 63 and 64 abut against the floating plate 70, and the floating plate 70 pulls the fifth elastic member 71, causing it to elastically extend. The floating plate 70, the first and second pressure plates 61 and 62 jointly support the display screen 300, ensuring a smooth display. Furthermore, when the foldable portion 330 is touched, it is less susceptible to damage or dents caused by external force, thereby improving the reliability of the display screen 300. When the rotating mechanism 100 is in the folded state, the foldable portion 330 of the display screen 300 bends and bulges outward toward the floating plate 70. The first and second pressure plate swing arms 63 and 64 rotate away from the fixed base 10, releasing the floating plate 70. The fifth elastic member 71 elastically retracts to its natural position. The rebound force of the fifth elastic member 71 drives the floating plate 70 downward toward the fixed base 10, creating a clearance space to clear the display screen 300 and prevent the floating plate 70 from squeezing and damaging the display screen 300. Of course, when the rotating mechanism 100 is in the folded state, the first elastic member 5641 may also be compressed due to the weight of the floating plate 70.

[0182] See also Figure 21 , Figure 21 yes Figure 5 The structure diagram of the rotating mechanism 100 shown is in a folded state.

[0183] When the rotating mechanism 100 is in the folded state, the foldable portion 330 of the display screen 300 is located inside the rotating mechanism 100. Specifically, the foldable portion 330 is located within the escape space. For example, the escape space is roughly shaped like a "teardrop." In this case, the rotating mechanism 100 avoids the rounded corners formed by the foldable portion 330 when it bends, preventing the foldable portion 330 from bending at a large angle. This prevents undesirable effects such as creases on the display screen 300, thereby extending the service life of the display screen 300.
