Description

Technical Field

[0001] This application relates to the field of electronic product technology, and in particular to a pivot mechanism and a foldable electronic device. Background Technology

[0002] With the gradual development of flexible screen technology, foldable electronic devices have emerged, becoming a hot technology due to their larger display area and excellent portability. Foldable electronic devices generally consist of a left shell, a right shell, a hinge mechanism, and a flexible screen. The flexible screen covers the left and right shells, which are located on the left and right sides of the hinge mechanism, respectively. Both the left and right shells can rotate relative to the hinge mechanism to fold together or unfold. During the repeated unfolding and closing of foldable electronic devices, the plastic deformation of the flexible screen itself inevitably causes creases to form on the flexible screen corresponding to the hinge mechanism area, severely affecting the overall aesthetics of the screen and the user experience.

[0003] To mitigate the impact of creases, one related technology involves installing a floating plate on the main support of the pivot mechanism. The floating plate is not fixedly connected to the flexible screen. During the process of the left and right shells closing or unfolding relative to each other, the floating plate can move up and down relative to the main support. When the left and right shells are unfolded to 180 degrees, the floating plate is at its highest position, thus providing support for the curved part of the flexible screen.

[0004] However, the role of the floating plate in the above method is to alleviate the screen crease by providing support after the flexible screen has deformed and creased, but it cannot fundamentally alleviate the crease problem of foldable electronic device screens. Summary of the Invention

[0005] This application provides a hinge mechanism and a foldable electronic device, which can fundamentally alleviate the crease problem of flexible screens in foldable electronic devices.

[0006] One embodiment of this application provides a pivot mechanism for a foldable electronic device, including: a bracket, a first swing arm, a connecting component, and a screen support structure. The bracket has connecting components on both sides, which are used to support the flexible screen of the foldable electronic device. One end of the first swing arm is rotatably connected to the bracket, and the other end of the first swing arm is connected to the connecting component. One end of the screen support structure is rotatably connected to the bracket, and the other end of the screen support structure is connected to the connecting component. The screen support structure is used to provide a thrust away from the bracket to the connecting component at least when the foldable electronic device is fully unfolded.

[0007] The pivot mechanism provided in this application embodiment has connecting components on both sides of the support. These connecting components support the flexible screen of the foldable electronic device. One end of the first swing arm is rotatably connected to the support, and the other end is connected to the connecting components. When the first swing arm rotates, the flexible screen rotates with the connecting components to achieve relative unfolding and folding of the flexible screen. The pivot mechanism also includes a screen-supporting structure. One end of the screen-supporting structure is rotatably connected to the support, and the other end is connected to the connecting components. The function of the screen-supporting structure is to provide a pushing force away from the support to the connecting components when the foldable electronic device is fully unfolded. This pushing force acts on the connecting components, causing them to tend to move to both sides relative to the flexible screen, thus pulling on the flexible screen. This improves the crease problem from the perspective of the flexible screen's own stress, fundamentally alleviating the crease problem of the flexible screen of the foldable electronic device. Furthermore, the tension of the screen-supporting structure itself can reduce the virtual displacement between the connecting components and the first swing arm, and between the support and the first swing arm, when the first swing arm rotates, alleviating the looseness of the pivot mechanism during rotation and improving the overall performance of the pivot mechanism.

[0008] In one possible implementation, the support structure is used to provide thrust away from the support to the connecting components when the foldable electronic device is closed, unfolded, and fully unfolded.

[0009] The supporting structure exerts a thrust on the connecting components, causing the connecting components to tend to move to both sides relative to the flexible screen when the foldable electronic device is closed, unfolded, and fully unfolded. This exerts a pulling effect on the flexible screen, improving the crease problem from the perspective of the flexible screen's own stress. Intervening before the flexible screen creases occur can fundamentally alleviate the crease problem of the flexible screen of foldable electronic devices.

[0010] In one possible implementation, the support structure is used to provide a thrust away from the support structure to the connecting components during and when the foldable electronic device is fully unfolded.

[0011] The supporting structure exerts a thrust on the connecting components, causing the connecting components to tend to move to both sides relative to the flexible screen during the unfolding process and when fully unfolded of the foldable electronic device. This exerts a pulling effect on the flexible screen, improving the crease problem from the perspective of the flexible screen's own stress. Intervening before the flexible screen creases occur can fundamentally alleviate the crease problem of the flexible screen of foldable electronic devices.

[0012] In one possible implementation, the bracket is provided with a first arc-shaped groove and a first rotating shaft, and one end of the first swing arm that is rotatably connected to the bracket is slidably disposed in the first arc-shaped groove around the first rotating shaft.

[0013] In this way, the displacement difference between the connecting components and the support frame during rotation allows the screen-supporting structure to be configured to be in a relaxed state when the flexible screen is closed. As the flexible screen gradually unfolds, the displacement difference between the connecting components and the support frame during rotation compresses the screen-supporting structure, providing a thrust away from the support frame to the connecting components during the unfolding process and when the foldable electronic device is fully unfolded. This prevents the flexible screen from experiencing lateral pulling forces when closed, reducing the risk of damage to the flexible screen.

[0014] In one possible implementation, the screen support structure includes: a first screen support member having a flexible segment and connecting segments located at both ends of the flexible segment, wherein one of the connecting segments located at both ends of the flexible segment is hinged to a bracket, and the other connecting segment is fixedly connected, hinged, or slidably connected to a connecting component.

[0015] The first screen support component can be compressed by the connecting component and the bracket to deform along its own axis. The flexible section is the main deformation area. The reaction force generated by the axial deformation of the first screen support component provides a thrust to the connecting component away from the bracket, making the connecting component tend to move to both sides of the flexible screen. This exerts a pulling effect on the flexible screen to both sides, thereby alleviating the crease of the flexible screen and improving the crease problem from the perspective of the screen's own stress deformation.

[0016] In one possible implementation, the pivot mechanism further includes: a second swing arm, on which a damping module is mounted, one end of the second swing arm being rotatably connected to the damping module, and the other end of the second swing arm being connected to a connecting assembly, wherein the damping module is used to provide damping force when the foldable electronic device is closed, during unfolding, and fully unfolded.

[0017] The damping module provides damping force when the foldable electronic device is closed, unfolded, and fully unfolded, enabling the foldable electronic device to remain in the closed, partially unfolded, and fully unfolded states.

[0018] In one possible implementation, the screen support structure includes: a second screen support member, a second swing arm being the second screen support member, and the second swing arm having a flexible segment.

[0019] The second swing arm can be compressed by the connecting component and the bracket to deform along its own axis. The flexible section is the main deformation area. The reaction force generated by the axial deformation of the second swing arm provides a thrust to the connecting component away from the bracket, making the connecting component tend to move to both sides of the flexible screen. This exerts a pulling effect on the flexible screen to both sides, thereby alleviating the crease of the flexible screen and improving the crease problem from the perspective of the screen's own stress deformation.

[0020] In one possible implementation, the pivot mechanism further includes a third swing arm. The connecting assembly includes a connecting block and a door panel, which are rotatably disposed relative to each other. A first sliding groove and a second sliding groove are respectively provided in the connecting block and the door panel. One end of the second swing arm connected to the connecting assembly is slidably disposed in the first sliding groove. A second arc-shaped sliding groove and a second pivot are provided on the bracket. One end of the third swing arm is slidably disposed in the second arc-shaped sliding groove around the second pivot, and the other end of the third swing arm is slidably disposed in the second sliding groove. The first swing arm is rotatably connected to the connecting assembly.

[0021] The first swing arm is rotatably connected to the connecting component, giving the connecting component a degree of rotational freedom. When the first swing arm drives the flexible screen to close, due to the stroke difference between the second and third swing arms and the first swing arm, the second and third swing arms will exert an inward force on the connecting component. The connecting component rotates and can fold the flexible screen into a teardrop shape. On the one hand, this ensures that the central angle of the inward fold of the flexible screen is large enough, preventing the bent part from being subjected to excessive bending and avoiding damage to the flexible screen due to excessive bending, while also minimizing bending marks. On the other hand, the top of the teardrop-shaped bent part has a smooth opening, allowing the two fixing parts to fit well with the two main parts of the foldable electronic device without leaving gaps.

[0022] In one possible implementation, when the second swing arm is the second screen support, during the unfolding of the foldable electronic device, one end of the second swing arm that is slidably connected to the first slide groove abuts against the side wall of the first slide groove away from the bracket.

[0023] When the second swing arm acts as the second screen support, during the unfolding of the foldable electronic device, one end of the second swing arm that is slidably connected to the first slide groove abuts against the side wall of the first slide groove away from the support. The displacement difference between the connecting components and the support caused by the first swing arm allows the third swing arm to abut against the end of the second slide groove before the foldable electronic device is fully unfolded. This causes the flexible segment to deform, and the second swing arm generates a reaction force towards both ends, which drives the connecting components to pull the flexible screen. This achieves intervention before the flexible screen develops creases, fundamentally alleviating the crease problem of the flexible screen of the foldable electronic device.

[0024] In one possible implementation, the screen support structure includes: a third screen support member, a third swing arm, the third swing arm having a flexible segment, and during the unfolding of the foldable electronic device, one end of the third swing arm that is slidably connected to the second slide groove abuts against the side wall of the second slide groove away from the bracket.

[0025] When the third swing arm acts as the third screen support, during the unfolding of the foldable electronic device, one end of the third swing arm that is slidably connected to the second slide groove abuts against the side wall of the second slide groove away from the support. Through the displacement difference formed by the connecting components relative to the support by the first swing arm, the end of the third swing arm abuts against the second slide groove before the foldable electronic device is fully unfolded, thereby causing the flexible segment to deform. The third swing arm generates a reaction force in both directions, which drives the connecting components to pull the flexible screen, thereby intervening before the flexible screen develops creases and fundamentally alleviating the crease problem of the flexible screen of the foldable electronic device.

[0026] In one possible implementation, one of the connecting block and the door panel is provided with a third arc-shaped sliding groove, and the other of the connecting block and the door panel is provided with an arc-shaped slider. The arc-shaped slider slides in the third arc-shaped sliding groove to achieve relative rotation between the connecting block and the door panel.

[0027] In one possible implementation, the hinge mechanism further includes a hinge cover, which is disposed on the side of the support away from the flexible screen of the foldable electronic device.

[0028] The hinge cover can conceal the bracket, ensuring the aesthetics of foldable electronic devices, and also protect the bracket from damage caused by impacts.

[0029] Another embodiment of this application provides a foldable electronic device, including: a flexible screen, two main bodies and the above-mentioned hinge mechanism, the two main bodies are respectively connected to both sides of the hinge mechanism, the two main bodies are unfolded and folded relative to each other through the hinge mechanism, and the flexible screen is attached to the upper surface of the two main bodies.

[0030] The foldable electronic device provided in this application embodiment includes connecting components on both sides of the support of the pivot mechanism. These connecting components support the flexible screen of the foldable electronic device. One end of the first swing arm is rotatably connected to the support, and the other end is connected to the connecting components. When the first swing arm rotates, the flexible screen rotates with the connecting components to achieve relative unfolding and folding of the flexible screen. The pivot mechanism also includes a screen-supporting structure. One end of the screen-supporting structure is rotatably connected to the support, and the other end is connected to the connecting components. The screen-supporting structure provides a pushing force away from the support to the connecting components, at least when the foldable electronic device is fully unfolded. This pushing force acts on the connecting components, causing them to tend to move to both sides relative to the flexible screen, thus pulling on the flexible screen. This improves the crease problem from the perspective of the flexible screen's own stress, intervening before creases form and fundamentally alleviating the crease problem of the flexible screen in the foldable electronic device. Furthermore, the tension of the screen-supporting structure itself can reduce the virtual displacement between the connecting components and the first swing arm, and between the support and the first swing arm, when the first swing arm rotates, alleviating the looseness of the pivot mechanism during rotation and improving the overall performance of the pivot mechanism.

[0031] In one possible implementation, the flexible screen includes a bending portion and two fixing portions, the two fixing portions being fixedly connected to two main body portions respectively, and the bending portion being configured to correspond to a rotating shaft mechanism.

[0065] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0066] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0067] The foldable electronic device provided in this application embodiment can be a mobile terminal such as a mobile phone, tablet computer, tablet computer accessories, wearable device, in-vehicle device, augmented reality (AR) device, virtual reality (VR) device, laptop computer, ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), etc., or it can be a professional shooting device such as a digital camera, SLR camera, mirrorless camera, action camera, gimbal camera, drone, etc. This application embodiment does not limit the specific type of foldable electronic device, as long as it is an electronic device that realizes the relative rotation of two main parts through a hinge mechanism. For ease of understanding, this application embodiment uses a foldable mobile phone as an example for explanation.

[0068] Figure 1 This is a schematic diagram of the structure of a foldable electronic device 10 provided in an embodiment of this application. Figure 2 This is an exploded view of the foldable electronic device 10 provided in an embodiment of this application, with reference to... Figure 1 and Figure 2As shown, the foldable electronic device 10 provided in this application embodiment includes: a flexible screen 100, two main body parts 200 and a pivot mechanism 300.

[0069] Specifically, the two main body parts 200 are respectively connected to both sides of the pivot mechanism 300, which enables the two main body parts 200 to unfold and fold relative to each other. For a mobile phone, the main body part 200 can be a mid-frame. It is understood that the specific structure of the main body part 200 can be determined according to the specific electronic device, and this application does not limit it, nor is it limited to the example of the main body part 200 being a mid-frame. Furthermore, the structures of the two main body parts 200 can be the same, not exactly the same, or completely different.

[0070] The flexible screen 100 is attached to the upper surface of the two main body parts 200. During the process of the two main body parts 200 unfolding and folding relative to each other, the flexible screen 100 is also simultaneously unfolded and folded.

[0071] The flexible screen 100 may include a display module and a transparent cover. The display module can display images and videos, and may employ technologies such as Liquid Crystal Display (LCD), Organic Light-Emitting Diode (OLED), Active-Matrix Organic Light-Emitting Diode (AMOLED), Flexible Light-Emitting Diode (FLED), and Quantum Dot Light-Emitting Diodes (QLED). The transparent cover covers the side of the display module facing away from the inside of the electronic device, protecting the display module. The transparent cover can be a glass cover, or other transparent materials that provide protection. The flexible screen 100 may also have touch functionality, meaning it can be a touchscreen.

[0072] Figure 3 This is a partial structural diagram of a foldable electronic device 10 in a folded state according to an embodiment of this application, with reference to... Figure 3As shown in the embodiment of this application, the flexible screen 100 in the foldable electronic device 10 may include a bending portion 110 and two fixing portions 120, which are respectively used to fixally connect to two main body portions 200 in the foldable electronic device 10. The bending portion 110 is provided corresponding to the pivot mechanism 300, and at least part of the bending portion 110 is not fixedly connected to the pivot mechanism 300 to meet the requirement of bending deformation of the bending portion 110 when folded. When the foldable electronic device 10 is in a folded state, the bending portion 110 can form an arc-shaped bending state.

[0073] For example, such as Figure 3 As shown, in the folded state of the foldable electronic device 10, the curved portion 110 of the flexible screen 100 is bent into a teardrop shape. This ensures that the central angle of the inward fold of the screen is large enough, preventing the curved portion 110 from undergoing excessive bending and avoiding damage to the flexible screen 100 due to over-bending, while also minimizing bending marks. Furthermore, the top of the teardrop-shaped curved portion 110 has a smooth taper, allowing the two fixing portions 120 to fit snugly against the two main body portions 200 of the foldable electronic device 10 without gaps. Of course, the folding shape of the curved portion 110 in the folded state is not limited to the teardrop shape shown above; it can also be other shapes.

[0074] However, during the use of the foldable electronic device 10, due to the repeated unfolding and folding of the flexible screen 100, creases will inevitably appear in the area of ​​the flexible screen 100 corresponding to the hinge mechanism 300, which will seriously affect the overall aesthetics of the flexible screen 100 and the user experience of consumers.

[0075] To address the aforementioned issues, a related technology includes a pivot mechanism comprising a main support, a swing arm, a left door panel, and a right door panel. The left and right door panels are rotatably connected to both sides of the main support via the swing arm. The two main bodies of the foldable electronic device are fixed to the left and right door panels, respectively. Additionally, a floating plate is mounted on the main support, located between the left and right door panels. The floating plate is not fixedly connected to the flexible screen. During the relative closure or unfolding of the two main bodies of the foldable electronic device, the floating plate can move up and down relative to the main support. When the two main bodies of the foldable electronic device are unfolded to their maximum extent, the floating plate is at its highest position. This allows the floating plate to support the curved portion of the flexible screen, thereby mitigating the crease problem of the flexible screen.

[0076] However, the above method alleviates the crease problem by supporting the flexible screen 100. In other words, this method only provides relief after the flexible screen 100 has already developed creases, and its effect is limited. Therefore, it is difficult to fundamentally alleviate the crease problem of the flexible screen 100 of the foldable electronic device 10.

[0077] In view of this, this application provides a pivot mechanism 300 and a foldable electronic device 10. The pivot mechanism 300 is used for the foldable electronic device 10 and includes a support 310, a first swing arm 320, and a connecting component 330. The connecting component 330 is provided on both sides of the support 310. The connecting component 330 is used to support the flexible screen 100 of the foldable electronic device 10. One end of the first swing arm 320 is rotatably connected to the support 310, and the other end is connected to the connecting component 330. When the first swing arm 320 rotates, the flexible screen 100 can rotate together with the connecting component 330 to realize the relative unfolding and folding of the flexible screen 100. The hinge mechanism 300 also includes a screen support structure 340. One end of the screen support structure 340 is rotatably connected to the bracket 310, and the other end is connected to the connecting component 330. The function of the screen support structure 340 is to provide a pushing force away from the bracket 310 to the connecting component 330 when the foldable electronic device 10 is closed, unfolded, and fully unfolded. Alternatively, it is used to provide a pushing force away from the bracket 310 to the connecting component 330 when the foldable electronic device 10 is unfolded and fully unfolded. The pushing force acts on the connecting component 330, causing the connecting component 330 to tend to move to both sides relative to the screen, generating a pulling effect on the screen. This improves the crease problem from the perspective of the screen's own stress, intervening before the flexible screen 100 creases, and fundamentally alleviating the crease problem of the flexible screen 100 of the foldable electronic device 10. Furthermore, the tension of the screen support structure 340 itself can reduce the virtual displacement between the connecting component 330 and the first swing arm 320 and between the bracket 310 and the first swing arm 320 when the first swing arm 320 rotates, alleviate the looseness of the rotating shaft mechanism 300 during rotation, and improve the overall performance of the rotating shaft mechanism 300.

[0078] The rotating shaft mechanism 300 provided in this application embodiment will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0079] Figure 4 This is a schematic diagram of the structure of a rotating shaft mechanism 300 provided in an embodiment of this application, with reference to... Figure 4 As shown, the pivot mechanism 300 provided in this embodiment includes a support 310 and a connecting component 330. The support 310 has connecting components 330 on both sides, and the connecting components 330 are used to support the flexible screen 100 of the foldable electronic device 10, such as... Figure 5 As shown, Figure 5 The diagram in the middle shows the connection between the flexible screen 100 and the connecting component 330 when the flexible screen 100 is in the unfolded state. The connection between the flexible screen 100 and the connecting component 330 can be achieved by a series of conventional connection methods such as bonding, snap-fitting, and welding. This application does not limit the connection method between the flexible screen 100 and the connecting component 330.

[0080] It should be noted that the connecting component 330 on one side of the bracket 310 can be one or multiple. Generally, to ensure consistent movement when the flexible screen 100 is folded, the connecting component 330 on one side of the bracket 310 is usually set as a single unit. For example, as shown... Figure 4 As shown, in some embodiments of this application, a connecting component 330 is provided on each side of the bracket 310, and the connecting component 330 is an integral piece with the same length as the bracket 310. Of course, in other embodiments of this application, multiple connecting components 330 may be provided on one side of the bracket 310, and the connecting components 330 are arranged along the length direction of the bracket 310.

[0081] To facilitate a clearer description of the diagram, the following will be used: Figure 4 A section of the central pivot mechanism 300 is enlarged. Figure 6 This is a partial structural schematic diagram of a rotating shaft mechanism 300 provided in an embodiment of this application, with reference to... Figure 6 As shown in the embodiment of this application, the rotating shaft mechanism 300 further includes a first swing arm 320. One end of the first swing arm 320 is rotatably connected to the bracket 310, and the other end of the first swing arm 320 is connected to the connecting assembly 330. The end of the first swing arm 320 connected to the connecting assembly 330 can be fixed, hinged, or otherwise.

[0082] For example, when the connecting component 330 does not require rotational freedom relative to the first swing arm 320, the first swing arm 320 and the connecting component 330 can be fixedly connected. When the connecting component 330 requires rotational freedom relative to the first swing arm 320, the first swing arm 320 and the connecting component 330 can be hinged, for example... Figure 6 In some embodiments of this application, the first swing arm 320 and the connecting component 330 are connected by a hinge. This application does not limit the connection method between the first swing arm 320 and the connecting component 330, as long as the first swing arm 320 can rotate relative to the support 310, so that the connecting component 330 can drive the flexible screen 100 to rotate, thereby achieving the purpose of unfolding and folding the flexible screen 100.

[0083] When the first swing arm 320 rotates around the bracket 310, the connecting assembly 330 rotates together with the first swing arm 320, such as Figure 7 As shown, combined Figure 5 When the first swing arms 320 on both sides of the bracket 310 rotate together and the two connecting components 330 come closer to each other, the flexible screen 100 can achieve the purpose of folding. When the two connecting components 330 move away from each other, the flexible screen 100 can achieve the purpose of unfolding.

[0084] It should be noted that the number of first swing arms 320 on one side of the bracket 310 can be one or more, for example, such as Figure 6and Figure 7 In the segment of the rotating shaft mechanism 300, there are two pairs of first swing arms 320, which are arranged opposite each other. It should also be noted that the number of first swing arms 320 on both sides of the bracket 310 can be the same or different, and the first swing arms 320 on both sides of the bracket 310 can be arranged opposite each other or staggered, as long as the first swing arms 320 on both sides of the bracket 310 can drive the connecting components 330 on both sides to move closer together and further apart. In practical applications, the first swing arms 320 are generally arranged in pairs and opposite each other, which helps to improve the synchronization performance of the rotating shaft mechanism 300.

[0085] Continue to refer to Figure 4 As shown in the embodiment of this application, the rotating shaft mechanism 300 further includes a screen support structure 340, one end of which is rotatably connected to the bracket 310, and the other end is connected to the connecting component 330. The end of the screen support structure 340 connected to the connecting component 330 can be fixed, hinged, or slidably connected, etc., and the specific connection method can be set according to specific needs. For example, when the first swing arm 320 and the connecting component 330 are fixedly connected, the screen support structure 340 and the connecting component 330 can also be fixedly connected. When the first swing arm 320 and the connecting component 330 are hinged, it means that the connecting component 330 needs to have other degrees of freedom. The screen support structure 340 and the connecting component 330 can be connected by hinges or slids, etc. This application does not limit the connection method of the screen support structure 340 and the connecting component 330.

[0086] in, Figure 8 This is a schematic diagram illustrating the function of the screen support structure 340 in the pivot mechanism 300 provided in an embodiment of this application. (Refer to...) Figure 8 As shown, Figure 8 The diagram illustrates the force exerted by the screen support structure 340 on the connecting component 330 when the foldable electronic device 10 is closed, unfolded, and fully unfolded. Figure 8 It is understood that the function of the screen-supporting structure 340 is to provide a pushing force away from the support 310 to the connecting component 330 when the foldable electronic device 10 is closed, unfolded, and fully unfolded. The pushing force of the screen-supporting structure 340 on the connecting component 330 allows the connecting component 330 to exert a pulling effect on both sides of the flexible screen 100 when the foldable electronic device 10 is closed, unfolded, and fully unfolded, thereby improving the crease problem from the perspective of the force on the flexible screen 100 itself.

[0087] Figure 9 This is a schematic diagram illustrating the function of the screen support structure 340 in the pivot mechanism 300 provided in an embodiment of this application. (Refer to...) Figure 9As shown, or, the function of the screen-supporting structure 340 is to provide a pushing force away from the support 310 to the connecting component 330 during the unfolding and fully unfolding of the foldable electronic device 10. The pushing force of the screen-supporting structure 340 on the connecting component 330 can cause the connecting component 330 to exert a pulling effect on both sides of the flexible screen 100 during the unfolding and fully unfolding of the foldable electronic device 100, thereby improving the crease problem from the perspective of the stress on the flexible screen 100 itself.

[0088] Of course, the screen support structure 340 can also provide a thrust away from the support 310 to the connection component 330 only when the foldable electronic device 10 is fully unfolded.

[0089] It should be noted that, in order to make the diagram clearer and simpler, Figure 8 and Figure 9 The illustrations of the flexible screen 100 during the closing and unfolding processes of the foldable electronic device 10 are omitted. It should also be noted that... Figure 8 and Figure 9 The middle arrow only indicates the direction of the force; the length of the arrow does not represent the magnitude of the force.

[0090] It is understood that the pivot mechanism 300 provided in this application embodiment has connecting components 330 on both sides of the support 310. The connecting components 330 are used to support the flexible screen 100 of the foldable electronic device 10. One end of the first swing arm 320 is rotatably connected to the support 310, and the other end is connected to the connecting component 330. When the first swing arm 320 rotates, the flexible screen 100 can rotate together with the connecting component 330 to realize the relative unfolding and folding of the flexible screen 100. The pivot mechanism 300 also includes a screen support structure 340. One end of the screen support structure 340 is rotatably connected to the support 310, and the other end is connected to the connecting component 330. The function of the screen support structure 340 is to provide a thrust away from the support 310 to the connecting component 330 at least when the foldable electronic device 10 is fully unfolded. The thrust applied to the connecting component 330 causes it to tend to move to both sides relative to the flexible screen 100, exerting a pulling effect on the flexible screen 100. This improves the crease problem from the perspective of the flexible screen 100's own stress. When the supporting structure 340 provides a thrust away from the bracket 310 to the connecting component 330 during the foldable electronic device 10's closing, unfolding, and fully unfolding processes, it can also intervene before creases form on the flexible screen 100, fundamentally alleviating the crease problem of the flexible screen 100 of the foldable electronic device 10. Furthermore, the tension of the supporting structure 340 itself can reduce the virtual displacement between the connecting component 330 and the first swing arm 320, and between the bracket 310 and the first swing arm 320, when the first swing arm 320 rotates, alleviating the looseness of the pivot mechanism 300 during rotation and improving the overall performance of the pivot mechanism 300.

[0091] It is easy to understand that the screen-supporting structure 340 continuously provides a pushing force away from the support 310 to the connecting component 330 when the foldable electronic device 10 is closed, unfolded, and fully unfolded. For example, a compressed structural member can be placed between the support 310 and the connecting component 330 as the screen-supporting structure 340. However, the flexible screen 100 does not need to have a pulling force to both sides at all times. The foldable electronic device 10 is generally closed for a relatively long time. If the flexible screen 100 also has a pulling force to both sides when closed, there may be a risk of damage to the flexible screen 100.

[0092] In order to ensure that the screen support structure 340 only provides a thrust away from the support bracket 310 to the connecting assembly 330 during the unfolding and fully unfolding of the foldable electronic device 10, Figure 10 This is a schematic cross-sectional view of the first swing arm 320 of the rotating shaft mechanism 300 provided in an embodiment of this application, with reference to... Figure 10 As shown, in some embodiments of this application, a first arc-shaped groove 311 and a first rotating shaft 312 are provided on the bracket 310, and one end of the first swing arm 320 connected to the bracket 310 is rotatably arranged around the first rotating shaft 312 in the first arc-shaped groove 311.

[0093] It is understandable that the end of the first swing arm 320 connected to the bracket 310 is rotatably positioned in the first arc-shaped slide groove 311 around the first rotating shaft 312, so that the connecting assembly 330 has a displacement difference relative to the bracket 310 when rotating. (Refer to...) Figure 10 As shown, this can be understood as, when the flexible screen 100 is closed (e.g. Figure 10 As shown in the left-hand side view of the first swing arm 320, the end of the first swing arm 320 connected to the bracket 310 is at the outermost edge of the first arc-shaped slide groove 311. At this time, the connecting component 330 is furthest from the bracket 310. As the flexible screen 100 gradually unfolds, the end of the first swing arm 320 connected to the bracket 310 gradually moves inward along the first arc-shaped slide groove 311, and the distance between the connecting component 330 and the bracket 310 gradually decreases. When the flexible screen 100 is fully unfolded (as shown in the left-hand side view of the first swing arm 320), the end of the first swing arm 320 connected to the bracket 310 gradually moves inward along the first arc-shaped slide groove 311, and the distance between the connecting component 330 and the bracket 310 gradually decreases. Figure 10 (As shown in the state of the first swing arm 320 on the right side), the end of the first swing arm 320 connected to the bracket 310 is located at the innermost side of the first arc-shaped slide groove 311. At this time, the connecting component 330 is closest to the bracket 310.

[0094] In this way, the screen-supporting structure 340 can be configured to be in a relaxed state when the flexible screen 100 is closed. As the flexible screen 100 gradually unfolds, the screen-supporting structure 340 is compressed by the displacement difference between the connecting component 330 and the support 310 during rotation. This allows the screen-supporting structure 340 to provide a pushing force away from the support 310 to the connecting component 330 during the unfolding process and when the foldable electronic device 10 is fully unfolded. As a result, the flexible screen 100 does not have a pulling force to the sides when closed, reducing the risk of damage to the flexible screen 100.

[0095] The screen support structure 340 can be a component already present in the pivot mechanism 300 or a separately added component. For example, Figure 11 This is a schematic diagram of the structure of the first screen support 341 provided in an embodiment of this application. Figure 12 This is a schematic cross-sectional view of the first support member 341 of the rotating shaft mechanism 300 provided in an embodiment of this application, with reference to... Figure 11 and Figure 12 As shown, in some embodiments of this application, the screen support structure 340 includes: a first screen support member 341, which is a separately added component.

[0096] The first screen support 341 has a flexible segment 3411 and connecting segments 3412 located at both ends of the flexible segment 3411. The flexible segment 3411 can be a curved beam structure. One of the connecting segments 3412 is hinged to the bracket 310, so that the first screen support 341 has only one degree of rotational freedom. The other connecting segment 3412 can be fixedly connected, hinged, or slidably connected to the connecting assembly 330, etc. It is only necessary to ensure that the first screen support 341 provides a thrust away from the bracket 310 to the connecting assembly 330 when the foldable electronic device 10 is closed, unfolded, and fully unfolded, or when the foldable electronic device 10 is unfolded and fully unfolded. For example, Figure 12 In the middle, another connecting segment 3412 is hinged to the connecting component 330.

[0097] exist Figure 12 In the example, the flexible screen 100 is closed (such as...). Figure 12 When the first swing arm 320 on the left side is in the relaxed state, the first screen support 341 is in the relaxed state. As the flexible screen 100 gradually unfolds to the fully unfolded state (as shown in the image), the first screen support 341 is in the relaxed state. Figure 12When the first swing arm 320 on the right side is in the state shown, due to the displacement difference between the connecting component 330 and the support 310 during rotation, the first screen support 341 is compressed by the connecting component 330 and the support 310 and deforms along its own axial direction. The flexible section 3411 is the main deformation area. The reaction force generated by the axial deformation of the first screen support 341 provides a thrust to the connecting component 330 away from the support 310, making the connecting component 330 tend to move to both sides of the flexible screen 100, and pulling the flexible screen 100 to both sides, thereby alleviating the crease of the flexible screen 100 and improving the crease problem from the perspective of the screen's own stress deformation.

[0098] The number of first screen support members 341 located on one side of the bracket 310 can be one or more. The first screen support members 341 located on both sides of the bracket 310 can be arranged opposite each other or staggered, and this application does not impose any restrictions on this. In practical applications, the first screen support members 341 are generally set as one or more pairs, with each pair of first screen support members 341 arranged opposite each other on the bracket 310 to improve the rotational synchronization of the rotating shaft mechanism 300.

[0099] Continue to refer to Figure 6 As shown, in some embodiments of this application, the pivot mechanism 300 may further include: a second swing arm 350, a damping module 360 ​​disposed on the bracket 310, one end of the second swing arm 350 being rotatably connected to the damping module 360, and the other end being connected to the connecting component 330. The end of the second swing arm 350 connected to the connecting component 330 may be fixed, hinged, or slidably connected, depending on the specific needs of the foldable electronic device 10.

[0100] The damping module 360 ​​provides damping force when the foldable electronic device 10 is closed, during unfolding, and fully unfolded, enabling the foldable electronic device 10 to maintain its closed, partially unfolded, and fully unfolded states. The specific operating principle of the damping module 360 ​​can be found in existing technologies and will not be elaborated upon here.

[0101] The number of second swing arms 350 located on one side of the bracket 310 can be one or more. The second swing arms 350 located on both sides of the bracket 310 can be arranged opposite each other or staggered. This application does not impose any restrictions on this. In practical applications, the second swing arms 350 are generally set as one or more pairs, with each pair of second swing arms 350 arranged opposite each other on the bracket 310 to improve the rotational synchronization of the rotating shaft mechanism 300.

[0102] Of course, this application is not limited to this. The second swing arm 350 can also be used as a screen support structure 340. It can be understood that the second swing arm 350 is used as a second screen support component, different from the first screen support component 341. The second swing arm 350 is provided with a flexible section, which can be a curved beam structure. The working principle of the second swing arm 350 generating thrust on the connecting component 330 can be referred to the first screen support component 341, and will not be repeated here.

[0103] Continue to refer to Figure 6 As shown, in some embodiments of this application, a synchronization module 370 may also be provided on the bracket 310. The synchronization module 370 is used to synchronize the multiple damping modules 360, so that the multiple second swing arms 350 can achieve synchronous rotation. The specific working principle of the synchronization module 370 can be found in the prior art, and will not be described in detail in this application.

[0104] Continue to refer to Figure 6 As shown, in some embodiments of this application, the pivot mechanism 300 may further include a third swing arm 380, which is connected between the bracket 310 and the connecting assembly 330. Figure 13 This is a schematic cross-sectional view of the second swing arm 350 of the rotating shaft mechanism 300 provided in an embodiment of this application. Figure 14 This is a schematic cross-sectional view of the third swing arm 380 of the rotating shaft mechanism 300 provided in an embodiment of this application, with reference to... Figure 13 and Figure 14 and combined Figure 6 As shown, in these embodiments, the connecting component 330 includes a connecting block 331 and a door panel 332. The door panel 332 can be used to support the flexible screen 100, and the connecting block 331 and the door panel 332 are rotatably arranged relative to each other. In this case, in order to ensure the direct force of the first screen support member 341 on the flexible screen 100, the first screen support member 341 can be connected to the door panel 332.

[0105] A first sliding groove 3311 is provided in the connecting block 331, and one end of the second swing arm 350 connected to the connecting assembly 330 is slidably disposed in the first sliding groove 3311. A second sliding groove 3321 is provided in the door panel 332, and one end of the third swing arm 380 connected to the connecting assembly 330 is slidably disposed in the second sliding groove 3321. Meanwhile, a second arc-shaped sliding groove 313 and a second rotating shaft 314 are provided on the bracket 310, and one end of the third swing arm 380 connected to the bracket 310 is rotatably disposed in the second arc-shaped sliding groove 313 around the second rotating shaft 314. This allows the first swing arm 320 to be rotatably connected to the connecting assembly 330, for example, as shown in... Figure 10 In the middle, the first swing arm 320 is hinged to the connecting block 331.

[0106] The first swing arm 320 is rotatably connected to the connecting component 330, allowing the connecting component 330 to have one degree of rotational freedom. When the first swing arm 320 drives the flexible screen 100 to close, due to the stroke difference between the second swing arm 350, the third swing arm 380 and the first swing arm 320, the second swing arm 350 and the third swing arm 380 will exert a certain force on the connecting component 330. Figure 13 and Figure 14 The force indicated by the dashed arrow in the diagram causes the connecting component 330 to rotate and fold the flexible screen 100 together as shown. Figure 3 The teardrop shape shown allows for a sufficiently large central angle at which the flexible screen 100 folds inward, preventing the bent portion 110 from undergoing excessive bending and thus avoiding damage to the flexible screen 100 due to over-bending. It also minimizes bending marks. Furthermore, the top of the teardrop-shaped bent portion 110 has a smooth taper, allowing the two fixing portions 120 to fit snugly against the two main body portions 200 of the foldable electronic device 10 without leaving any gaps.

[0107] The purpose of the second swing arm 350 sliding in the first slide groove 3311 is to prevent jamming before the connecting component 330 folds the flexible screen 100 into a teardrop shape. The purpose of configuring the second swing arm 350 to slide in the first slide groove 3311 and the third swing arm 380 to slide in the second slide groove 3321 is that when the connecting block 331 reaches its rotation limit, since the connecting block 331 and the door panel 332 are relatively rotated, the third swing arm 380 can continue to drive the door panel 332 to fold the flexible screen 100 into a teardrop shape, thus preventing jamming before the flexible screen 100 is folded into a teardrop shape.

[0108] The number of third swing arms 380 located on one side of the bracket 310 can be one or more. The third swing arms 380 located on both sides of the bracket 310 can be arranged opposite each other or staggered. This application does not impose any restrictions on this. In practical applications, the third swing arms 380 are generally set as one or more pairs, with each pair of third swing arms 380 arranged opposite each other on the bracket 310 to improve the rotational synchronization of the rotating shaft mechanism 300.

[0109] Figure 15 This is a schematic diagram illustrating the engagement between the connecting block 331 and the door panel 332 according to an embodiment of this application. (Refer to...) Figure 15 As shown, in some embodiments of this application, one of the connecting block 331 and the door panel 332 is provided with a third arc-shaped sliding groove 3322, and the other of the connecting block 331 and the door panel 332 is provided with an arc-shaped slider 3312. For example, as... Figure 15As shown, an arc-shaped slider 3312 is provided on the connecting block 331, and a third arc-shaped groove 3322 is provided on the door panel 332. The arc-shaped slider 3312 is slidably arranged in the third arc-shaped groove 3322 to realize the relative rotation between the connecting block 331 and the door panel 332.

[0110] Of course, this application does not end here. Figure 16 This is a schematic diagram of the structure of the third swing arm 380 provided in an embodiment of this application, with reference to... Figure 16 As shown, in some embodiments of the application, the third swing arm 380 can be used as a screen support structure 340. This can be understood as the third swing arm 380 being a third screen support component distinct from the first and second screen support components. The third swing arm 380 is provided with a flexible section 381, which can be formed by weakening the stiffness of this area to create a curved beam structure. A simplified structural form can be found by referring to... Figure 17 As shown, one end can be hinged to the bracket 310, and the other end is slidably connected to the connecting assembly 330. It is understood that in some embodiments of this application, the first screen support 341 and the second screen support can also adopt the following... Figure 17 The form shown.

[0111] When the third swing arm 380 acts as the third screen support, during the unfolding of the foldable electronic device 10, one end of the third swing arm 380 that is slidably connected to the second slide groove 3321 abuts against the side wall of the second slide groove 3321 away from the bracket 310. Due to the displacement difference between the connecting component 330 and the bracket 310 caused by the first swing arm 320, the end of the third swing arm 380 abuts against the second slide groove 3321 before the foldable electronic device 10 is fully unfolded. This causes the flexible segment 381 to deform, and the flexible segment 381 of the third swing arm 380 generates a reaction force towards both ends, which drives the connecting component 330 to pull the flexible screen 100. This achieves intervention before the flexible screen 100 develops creases, fundamentally alleviating the crease problem of the flexible screen 100 of the foldable electronic device 10.

[0112] The working principle of the third swing arm 380 can be found in [reference]. Figure 18 , Figure 19 and Figure 20 As shown:

[0113] Figure 18 A state diagram of the third swing arm 380 provided in an embodiment of this application, with reference to Figure 18 As shown, when the foldable electronic device 10 is in the folded state, the third swing arm 380 is in the relaxed state, and the sliding section of the third swing arm 380 in the second slide groove 3321 does not abut against the side wall of the second slide groove 3321 away from the bracket 310.

[0114] Figure 19A state diagram of the third swing arm 380 provided in an embodiment of this application, with reference to Figure 19 As shown, when the foldable electronic device 10 is unfolding, the sliding section of the third swing arm 380 in the second slide groove 3321 abuts against the side wall of the second slide groove 3321 away from the bracket 310, thereby causing the flexible section 381 of the third swing arm 380 to deform. The flexible section 381 of the third swing arm 380 generates a reaction force towards both ends, which drives the connecting component 330 to pull the flexible screen 100, thereby intervening before the flexible screen 100 develops creases, fundamentally alleviating the crease problem of the flexible screen 100 of the foldable electronic device 10.

[0115] Figure 20 A state diagram of the third swing arm 380 provided in an embodiment of this application, with reference to Figure 20 As shown, when the foldable electronic device 10 is in the fully unfolded state, the third swing arm 380 still abuts against the side wall of the second slide groove 3321 away from the bracket 310. The flexible section 381 of the third swing arm 380 generates a reaction force to both ends, which drives the connecting component 330 to pull the flexible screen 100, thereby intervening before the flexible screen 100 develops creases, fundamentally alleviating the crease problem of the flexible screen 100 of the foldable electronic device 10.

[0116] When the second swing arm 350 is the second screen support, it is also necessary for the end of the second swing arm 350 connected to the first slide groove 3311 to abut against the side wall of the first slide groove 3311 away from the bracket 310 during the unfolding process of the foldable electronic device 10. Its working principle can be referred to the third swing arm 380, and will not be repeated here.

[0117] It should be noted that the terms "first screen support component 341," "second screen support component," and "third screen support component" in this article are only used to distinguish similar objects and are not used to describe the order or sequence of these three components. Furthermore, "first screen support component 341," "second screen support component," and "third screen support component" can exist individually, simultaneously, or in pairs.

[0118] Please refer to Figure 3 As shown, in some embodiments of this application, the pivot mechanism 300 may further include: a pivot cover 390, which covers the side of the bracket 310 away from the flexible screen 100 to shield the bracket 310, ensuring the aesthetics of the foldable electronic device 10, and also to protect the bracket 310 from being exposed and damaged by collision.

[0119] In summary, the pivot mechanism 300 provided in this application embodiment can function during the deformation of the flexible screen 100, changing its stress deformation state and fundamentally improving the crease problem of the flexible screen 100. Furthermore, the pivot mechanism 300 provided in this application embodiment has a simple structure, few parts, and a simple assembly process. In addition, the first screen support member 341, the second screen support member, and the third screen support member have good connectivity with the bracket 310 and the connecting assembly 330, exhibiting strong reliability and adaptability. Moreover, the first screen support member 341, the second screen support member, and the third screen support member can also reduce the virtual displacement generated between the connecting assembly 330 and the bracket 310 during operation of the pivot mechanism 300, alleviating the looseness of the pivot mechanism 300 during rotation and improving the overall performance of the pivot mechanism 300.
