Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a rotating shaft mechanism and electronic equipment. Background Technology

[0002] With the gradual maturation of flexible display technology, the way electronic devices display technology has undergone tremendous changes. Foldable flexible screen mobile phones, foldable flexible screen tablets, and wearable electronic devices with foldable flexible screens are a major direction for the evolution of future smart electronic devices.

[0003] As a key component for foldable electronic devices to achieve closure and unfolding functions, the hinge mechanism needs to provide sufficient space to accommodate the curved portion of the flexible display screen when the device is closed, and reliably support the flexible display screen when the device is unfolded. However, existing folding solutions, while meeting these two conditions, have certain shortcomings in the precision of motion control of the hinge mechanism, affecting the overall reliability of the electronic device. Summary of the Invention

[0004] This application provides a rotating shaft mechanism and an electronic device to improve the motion accuracy of the rotating shaft mechanism, thereby improving the overall reliability of the electronic device.

[0005] In a first aspect, this application provides a rotating shaft mechanism, which may include a first rotating module, a second rotating module, and a module support. The first rotating module and the second rotating module may be respectively disposed on both sides of the module support. The first rotating module may include a first swing arm, a first support arm, a first housing support, a first door panel, and a first connecting rod. The first door panel can be used to support a flexible display screen. At least a portion of the first swing arm and the second support arm may be disposed on the side of the first door panel opposite to the flexible display screen. The first swing arm and the first support arm may be distributed along the length direction of the rotating shaft mechanism, and the first swing arm and the first support arm are rotatably connected to the module support. The rotation axes of the first support arm and the first swing arm on the module support are different and parallel to each other. At least a portion of the first housing support may be disposed on the side of the first swing arm and the first support arm opposite to the first door panel. The first swing arm is rotatably connected to the first housing support, the first support arm is slidably connected to the first housing support, and the first door panel is rotatably connected to the first housing support. One end of the first connecting rod may be rotatably connected to the first swing arm, and the other end may be rotatably connected to the first door panel. The second rotating module may include a second swing arm, a second support arm, a second housing bracket, a second door panel, and a second connecting rod. The second door panel can be used to support the flexible display screen. The second swing arm and the second support arm can be distributed along the length direction of the rotating shaft mechanism, and the second swing arm and the second support arm are respectively rotatably connected to the module bracket. The rotation axes of the second support arm and the second swing arm on the module bracket are different and parallel to each other. At least a portion of the second housing bracket can be disposed on the side of the second swing arm and the second support arm away from the second door panel. The first swing arm is rotatably connected to the second housing bracket, the second support arm is slidably connected to the second housing bracket, and the second door panel is rotatably connected to the second housing bracket. One end of the second connecting rod can be rotatably connected to the second swing arm, and the other end can be rotatably connected to the second door panel. In this way, when the first and second housing supports rotate relative to each other, the first housing support can drive the first support arm and the first swing arm to rotate around the module support, and the first connecting rod can drive the first door panel to rotate relative to the first housing support, so that the end of the first door panel near the module support moves away from the module support. Correspondingly, the second housing support can drive the second support arm and the second swing arm to rotate around the module support, and the second connecting rod can drive the second door panel to rotate relative to the second housing support, so that the end of the second door panel near the module support moves away from the module support. In this way, when the first door panel rotates to the first position and the second door panel rotates to the second position, they can form an angle, and together with the module support, they can form a screen-accommodating space for accommodating the flexible display screen. Specifically, the first position here refers to the position where the first and second door panels are in the closed state of the electronic device, and in this position, the first door panel and the second door panel can form an acute angle. It should be noted that the angle here can be the angle formed directly between the first and second door panels, or the angle formed by the extension lines of the two.

[0006] In the above scheme, based on the rotational connections between the first swing arm and the first housing support, between the first housing support and the first door panel, between the first door panel and the first connecting rod, and between the first connecting rod and the first swing arm, the first swing arm, the first housing support, the first door panel, and the first connecting rod can roughly form a four-bar linkage. In this case, the first door panel can rotate under the joint constraint of the first connecting rod and the first housing support. Similarly, the second swing arm, the second housing support, the second door panel, and the second connecting rod can also roughly form a four-bar linkage, and the second door panel can rotate under the joint constraint of the second connecting rod and the second housing support. This design can effectively improve the motion accuracy of the pivot mechanism during the unfolding and closing process, and improve the force state of the first and second door panels, enabling the first and second door panels to move stably and accurately to the designated positions, thereby improving the overall structural reliability of electronic devices using this pivot mechanism.

[0007] In some possible implementations, the first rotating module may further include a third door panel, which may be located on the side of the first door panel near the module support to jointly support the flexible display screen with the first door panel; the third door panel may be rotatably connected to the first door panel, and may also be slidably connected to the module support, and may rotate relative to the module support. Similarly, the second rotating module may further include a fourth door panel, which may be located on the side of the second door panel near the module support to jointly support the flexible display screen with the second door panel; the fourth door panel may be rotatably connected to the second door panel, and may also be slidably connected to the module support, and may rotate relative to the module support. By designing the pivot mechanism as a four-door panel structure, in the closed state, the screen-accommodating space formed by the pivot mechanism can better fit the bending shape of the flexible display screen, thereby helping to improve the reliability of the flexible display screen.

[0008] In some possible implementations, a first mounting groove may be provided on the side of the first swing arm facing the first door panel, and a second mounting groove may be provided on the side of the first door panel facing the first swing arm. One end of the first connecting rod is rotatably disposed in the first mounting groove, and the other end of the first connecting rod is rotatably disposed in the second mounting groove, thereby achieving a rotatable connection between the first connecting rod and the first swing arm and the first door panel. Similarly, a third mounting groove may be provided on the side of the second swing arm facing the second door panel, and a fourth mounting groove may be provided on the side of the second door panel facing the second swing arm. One end of the second connecting rod is rotatably disposed in the third mounting groove, and the other end of the second connecting rod is rotatably disposed in the fourth mounting groove, thereby achieving a rotatable connection between the second connecting rod and the second swing arm and the second door panel.

[0009] In some possible implementations, a first protrusion may be provided on the side of the first door panel facing away from the flexible display screen. Along the length of the rotating shaft mechanism, this first protrusion may be located on one side of the first support arm. A first rotating groove may be provided on the side of the first protrusion facing the first support arm, and a first sliding shaft may be provided on the side of the first support arm facing the first protrusion. This first sliding shaft is slidably disposed within the first rotating groove. Thus, the relative rotation of the first door panel bracket and the first support arm can be achieved through the cooperation of the first sliding shaft and the first rotating groove. Similarly, a second protrusion may be provided on the side of the second door panel facing away from the flexible display screen. Along the length of the rotating shaft mechanism, this second protrusion may be located on one side of the second support arm. A second rotating groove may be provided on the side of the second protrusion facing the second support arm, and a second sliding shaft may be provided on the side of the first support arm facing the second protrusion. This second sliding shaft is slidably disposed within the second rotating groove. Thus, the relative rotation of the second door panel bracket and the second support arm can be achieved through the cooperation of the second sliding shaft and the second rotating groove.

[0010] In some possible implementations, a first arc-shaped groove and a second arc-shaped groove may be respectively provided on both sides of the module bracket. The first swing arm may have a first arc-shaped rotating block, which is disposed in the first arc-shaped groove and can rotate around the arc-shaped surface of the first arc-shaped groove, thereby realizing the rotation of the first swing arm around the module bracket. The second swing arm may have a second arc-shaped rotating block, which is disposed in the second arc-shaped groove and can rotate around the arc-shaped surface of the second arc-shaped groove, thereby realizing the rotation of the second swing arm around the module bracket.

[0011] In some possible implementations, the first housing support may be provided with a first sliding groove, and the first support arm is slidably disposed within the first sliding groove, thereby achieving a sliding connection between the first housing support and the first support arm. Similarly, the second housing support may be provided with a second sliding groove, and the second support arm is slidably disposed within the second sliding groove, thereby achieving a sliding connection between the second housing support and the second support arm.

[0012] In addition, the wall of the first slide groove may be provided with a first slide rail, and the side of the first support arm may be provided with a first slider. The first slider is slidably disposed within the first slide rail to limit the movement of the first support arm within the first slide groove, and the first slide groove provides guidance for the sliding of the first support arm within the first slide groove, thereby improving the motion stability of the first support arm. Similarly, the wall of the second slide groove may be provided with a second slide rail, and the side of the second support arm may be provided with a second slider. The second slider is slidably disposed within the second slide rail to limit the movement of the second support arm within the second slide groove, and the second slide groove provides guidance for the sliding of the second support arm within the second slide groove, thereby improving the motion stability of the second support arm.

[0013] In some possible implementations, the first housing support may be provided with a third arc-shaped rotating block, and the first door panel may be provided with a third arc-shaped groove. The third arc-shaped rotating block can be rotatably disposed in the third arc-shaped groove, thereby rotatably connecting the first housing support and the first door panel. The second housing support may be provided with a fourth arc-shaped rotating block, and the second door panel may be provided with a fourth arc-shaped groove. The fourth arc-shaped rotating block can be rotatably disposed in the fourth arc-shaped groove, thereby rotatably connecting the second housing support and the second door panel.

[0014] In some possible implementations, a fifth arc-shaped rotating block may be provided on the side of the third door panel facing away from the flexible display screen, and a fifth arc-shaped groove may be provided on the side of the first door panel facing away from the flexible display screen. The fifth arc-shaped rotating block can be rotatably disposed within the fifth arc-shaped groove, thereby rotatably connecting the first door panel and the third door panel. A sixth arc-shaped rotating block may be provided on the side of the fourth door panel facing away from the flexible display screen, and a sixth arc-shaped groove may be provided on the side of the second door panel facing away from the flexible display screen. The sixth arc-shaped rotating block can be disposed within the sixth arc-shaped groove, thereby rotatably connecting the second door panel and the fourth door panel.

[0015] In some other possible implementations, the first door panel and the third door panel can also be connected by a first flexible member, in which case the first door panel and the third door panel can achieve relative rotation by deformation of the first flexible member. Similarly, the second door panel and the fourth door panel can be connected by a second flexible member, thereby achieving relative rotation by deformation of the second flexible member.

[0016] Optionally, the first flexible member may be disposed on the side of the first door panel and the third door panel away from the flexible display screen, and the first flexible member may be bonded to the first door panel and the third door panel respectively; the second flexible member may be disposed on the side of the second door panel and the fourth door panel away from the flexible display screen, and the second flexible member may be bonded to the second door panel and the fourth door panel respectively.

[0017] For example, in the above scheme, the first flexible member and the second flexible member can be made of materials such as carbon fiber and Kevlar.

[0018] Optionally, the first flexible member can be connected between the first door panel and the third door panel. In this case, the first door panel and the third door panel can be a single-piece molded structure, and the deformable first flexible member is formed by thinning the connection between the two. Similarly, the second flexible member can also be connected between the second door panel and the fourth door panel. The second door panel and the fourth door panel can be a single-piece molded structure, and the second flexible member can be formed by thinning the connection between the second door panel and the fourth door panel.

[0019] In some possible implementations, a first track groove and a second track groove may be respectively provided on both sides of the end of the module bracket. A first extension wall may be provided on the side of the third door panel facing away from the flexible display screen. The first extension wall may have a first fixed shaft arranged along the length direction of the rotating shaft mechanism. This first fixed shaft is slidably disposed within the first track groove, thereby rotatably connecting the third door panel to the module bracket. A second extension wall may be provided on the side of the fourth door panel facing away from the flexible display screen. The second extension wall may have a second fixed shaft arranged along the length direction of the rotating shaft mechanism. This second fixed shaft is slidably disposed within the second track groove, thereby rotatably connecting the fourth door panel to the module bracket.

[0020] In some possible implementations, the first door panel may include a first door panel body and a first door panel bracket. The first door panel body may be fixed to the side of the first door panel bracket facing the flexible display screen to support the flexible display screen. The second door panel may include a second door panel body and a second door panel bracket. The second door panel body may be fixed to the side of the second door panel bracket facing the flexible display screen to support the flexible display screen. By designing the first and second door panels as separate structures for the door panel bracket and the door panel body, the processing difficulty of the first and second door panels is reduced, and their manufacturing cost is lowered.

[0021] In one alternative, the first door panel body and the first door panel bracket can be fixedly connected by welding, riveting or other methods, and the second door panel body and the second door panel bracket can also be fixedly connected by welding, riveting or other methods.

[0022] In another alternative, the first door panel body and the first door panel bracket can be an integral structure, and the second door panel body and the second door panel bracket can also be an integral structure. This helps to simplify the structure of the first door panel and the second door panel, thereby simplifying the overall structure of the pivot mechanism and reducing its assembly difficulty.

[0023] In some possible implementations, the pivot mechanism may also include a base to which the module bracket can be fixed, thereby providing support.

[0024] In an alternative embodiment, the base may be supported on the side of the module bracket opposite to the first and second door panels.

[0025] In another alternative, the base can also be positioned between the first door panel and the second door panel. When the pivot mechanism is in the unfolded state, the side of the base facing away from the module bracket is coplanar with the side of the first door panel facing away from the first swing arm and the side of the second door panel facing away from the second swing arm. In this case, the base, together with the first and second door panels, can support the flexible display screen, thereby improving the reliability of the flexible display screen.

[0026] In some possible implementations, the rotating shaft mechanism may further include a synchronization component, which may include a first drive gear disposed at the end of the first support arm and a second drive gear disposed at the end of the second support arm, the two drive gears meshing together. Thus, when one support arm rotates about the base, it can drive the other support arm to rotate synchronously at the same angle in opposite or opposing directions.

[0027] In addition, the synchronization component may also include an even number of driven gears, which can be arranged between two driving gears so that the two driving gears can rotate synchronously through the even number of driven gears. This helps to improve the stability of the movement of the synchronization component, thereby improving the reliability of the synchronous rotation of the two support arms.

[0028] Secondly, this application also provides an electronic device, which may include a first housing, a second housing, a flexible display screen, and a pivot mechanism as described in any possible embodiment of the first aspect. The first housing and the second housing may be disposed on opposite sides of the pivot mechanism, the first housing being fixedly connected to a first housing support, and the second housing being fixedly connected to a second housing support; the flexible display screen may continuously cover the first door panel, the second door panel, and the pivot mechanism, and the flexible display screen is fixedly connected to the first door panel and the second door panel.

[0029] The electronic device provided in this application, when in the unfolded state, utilizes a hinge mechanism to provide flat support for the flexible display screen, ensuring the integrity of the device's form in this unfolded state. When in the closed state, the hinge mechanism forms a teardrop-shaped space to accommodate the screen, thus meeting the bending requirements of the flexible display screen and reducing the risk of compression or stretching. When the electronic device switches between the unfolded and closed states, the first swing arm, first housing support, first door panel, and first connecting rod of the first rotating module can form a four-bar linkage, and the second swing arm, second housing support, second door panel, and second connecting rod of the second rotating module can also form a four-bar linkage. By utilizing the motion characteristics of the four-bar linkages on both sides, the movement accuracy of the electronic device during unfolding and closing is improved, thereby enhancing the overall reliability of the device.

[0077] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. The same reference numerals in the figures denote the same or similar structures, and therefore repeated descriptions of them will be omitted. The terms expressing position and direction described in the embodiments of this application are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this application. The accompanying drawings of the embodiments of this application are only for illustrating relative positional relationships and do not represent actual scale.

[0078] It should be noted that specific details are set forth in the following description to facilitate understanding of this application. However, the embodiments of this application can be implemented in many ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the embodiments of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0079] refer to Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. The electronic device can be a mobile phone, a personal digital assistant (PDA), a laptop computer, a tablet computer, or other devices with foldable functionality. Figure 1 The illustrated embodiment uses a laptop computer as an example. The electronic device may include a hinge mechanism 1, a flexible display screen (not shown), and two housings. For ease of description, the two housings can be named a first housing 2 and a second housing 3, respectively. The first housing 2 and the second housing 3 are located on both sides of the hinge mechanism 1 and can rotate around the hinge mechanism 1. During use, the electronic device can be closed and unfolded according to different usage scenarios. The electronic device provided in this application embodiment can be an inward-folding electronic device. Figure 1 In the illustrated embodiment, the electronic device is in an intermediate state between a closed state and an unfolded state, showing the structure of the support surface 1a of the hinge mechanism 1, the support surface 2a of the first housing 2, and the support surface 3a of the second housing 3. Here, the support surface 1a of the hinge mechanism 1 refers to the surface of the hinge mechanism 1 used to support the flexible display screen, the support surface 2a of the first housing 2 refers to the surface of the first housing 2 used to support the flexible display screen, and the support surface 3a of the second housing 3 refers to the surface of the second housing 3 used to support the flexible display screen.

[0080] The flexible display screen can continuously cover the support surface 2a of the first housing 2, the support surface 1a of the rotating mechanism, and the support surface 3a of the second housing 3. The flexible display screen can be fixedly connected to the support surfaces 2a of the first housing 2 and 3a of the second housing 3, and the connection method can be, but is not limited to, adhesive bonding. Thus, when the electronic device is in the unfolded state, the rotating mechanism 1, the first housing 2, and the second housing 3 can support the flexible display screen. During the relative rotation of the first housing 2 and the second housing 3 from the unfolded state to the closed state, or from the closed state to the unfolded state, the flexible display screen can be bent or flattened along with the first housing 2 and the second housing 3.

[0081] refer to Figure 2 As shown, Figure 2 for Figure 1 The diagram shows a partial exploded view of the electronic device. In this embodiment, the first housing 2 and the second housing 3 can be located on opposite sides of the rotating shaft mechanism 1. The first housing 2 has a first receiving groove 201 on the side near the rotating shaft mechanism 1, and the second housing 3 has a second receiving groove 301 on the side near the rotating shaft mechanism 1. One side of the rotating shaft mechanism 1 can be partially received in the first receiving groove 201, and the other side of the rotating shaft mechanism 1 can be partially received in the second receiving groove 301. The rotating shaft mechanism 1 can include one main shaft unit 11 or multiple main shaft units 11. Figure 2 The diagram illustrates a pivot mechanism 1 comprising four main spindle units 11, which are spaced apart along the length of the pivot mechanism 1. The length of the pivot mechanism 1 can be understood as the extension direction of the axis of rotation of the first housing 2 and the second housing 3 about the pivot mechanism 1. The first housing 2 and the second housing 3 can be rotatably connected via one or more main spindle units 11, thereby effectively improving the stability of the rotation of the first housing 2 and the second housing 3 of the electronic device relative to the pivot mechanism 1.

[0082] Additionally, the rotating shaft mechanism 1 may also include a base 12 disposed along its length, which can be used to support one or more spindle units 11. It is worth noting that in some possible embodiments, when there are multiple spindle units 11, each of the multiple spindle units 11 may use a single base 12 as a supporting component, thereby improving the integration level of the rotating shaft mechanism 1. In other possible embodiments, the rotating shaft mechanism 1 may provide a separate base 12 for each spindle unit 11, so that each spindle unit 11 uses a corresponding base 12 as a supporting component. Figure 2 The embodiment shown is illustrated using the rotating shaft mechanism 1 as an example, which includes an integral base 12.

[0083] Please refer to the above. Figure 3 and Figure 4 As shown, Figure 3This is a partial structural diagram of the spindle unit 11 provided in an embodiment of this application. Figure 4 for Figure 3 The diagram shows an exploded view of the spindle unit 11. In this embodiment, the spindle unit 11 may include a module support 111 and two rotating modules, namely a first rotating module 112 and a second rotating module 113. The module support 111 may be fixedly connected to the base 12, and it may serve as a load-bearing component for the first rotating module 112 and the second rotating module 113. The first rotating module 112 and the second rotating module 113 are respectively disposed on both sides of the module support 111.

[0084] In one possible implementation, the base 12 may be disposed on the side of the pivot mechanism opposite to its support surface. Additionally, the pivot mechanism may also include a cover plate 13, which may cover the side of the base 12 away from the support surface of the pivot mechanism. Exemplarily, the cover plate 13 and the base 12 may be, but are not limited to, fixed by adhesive bonding. (See also...) Figure 2 As shown, when the electronic device is in the unfolded state, the cover plate 13 is hidden within the first receiving groove 201 of the first housing 2 and the second receiving groove 301 of the second housing 3. At this time, the outer surfaces of the first housing 2 and the second housing 3 together constitute the outer surface of the electronic device. When the electronic device switches from the open state to the closed state, as the first housing 2 and the second housing 3 rotate, the surface of the cover plate 13 facing away from the base 12 is gradually exposed from within the first receiving groove 201 of the first housing 2 and the second receiving groove 301 of the second housing 3. When the electronic device switches to the closed state, the outer surfaces of the first housing 2, the second housing 3, and the surface of the cover plate 13 facing away from the base 12 together constitute the outer surface of the electronic device.

[0085] For ease of description, in the following embodiments of this application, the spindle unit 11 is mainly described using the specific arrangement of the first rotating module 112 as an example, while the second rotating module 113 can be set up with reference to the first rotating module 112. It should be noted that the design of the second rotating module 113 can be completely consistent with the first rotating module 112; or it can only refer to the components and connection relationships included in the first rotating module 112, and other parameters can be adjusted adaptively, without requiring complete consistency.

[0086] Please refer to the above. Figure 5 and Figure 6 As shown, Figure 5 This is a partial structural diagram of the rotating shaft mechanism provided in the embodiment of this application in its unfolded state. Figure 6This is a partially exploded structural diagram of the rotating shaft mechanism provided in the embodiment of this application in its unfolded state. In this embodiment, the first rotating module 112 may include a first swing arm 1121, a first support arm 1122, a first housing bracket 1123, and a first door panel 1124. The first door panel 1124 can be used to support the flexible display screen and is fixedly connected to the flexible display screen. The first swing arm 1121 and the first support arm 1122 may be disposed on the side of the first door panel 1124 away from the flexible display screen. The first swing arm 1121 and the first support arm 1122 may be distributed along the length direction of the rotating shaft mechanism, and both may be rotatably connected to the module bracket 111. The first housing bracket 1123 may be located on the side of the first swing arm 1121 and the first support arm 1122 away from the first door panel 1124. The first housing bracket 1123 can be fixedly connected to the first housing. The first housing bracket 1123 can be rotatably connected to the first swing arm 1121 and slidably connected to the first support arm 1122. During the unfolding and folding of the rotating shaft mechanism, the first housing bracket rotates synchronously with the first housing, thereby driving the first swing arm 1121 and the first support arm 1122 to rotate synchronously around the module bracket 111. Additionally, the first housing bracket 1123 can also be rotatably connected to the first door panel 1124, so that during the rotation of the first housing bracket 1123, the first door panel 1124 can also rotate along a certain trajectory. This provides flat support for the flexible display screen in the unfolded state of the rotating shaft mechanism and provides a certain amount of space for the flexible display screen in the folded state of the rotating shaft mechanism, ensuring the reliability of the flexible display screen.

[0087] Figure 7 This is a schematic diagram of the structure of the first swing arm provided in an embodiment of this application. It can be referred to in conjunction with this diagram. Figure 6 and Figure 7In this embodiment, the module bracket 111 may include a swing arm bracket 1111, and a first swing arm 1121 is rotatably connected to the swing arm bracket 1111, with the rotation axis of the first swing arm 1121 arranged along the length direction of the rotating shaft mechanism. Specifically, the end of the first swing arm 1121 used for connection with the swing arm bracket 1111 may be provided with a first arc-shaped rotating block 11211. Correspondingly, the swing arm bracket 1111 may be provided with a first arc-shaped groove 11111, and the first arc-shaped rotating block 11211 of the first swing arm 1121 can be accommodated in the first arc-shaped groove 11111 and can rotate along the arc surface of the first arc-shaped groove 11111, thereby realizing the rotation of the first support arm 1122 around the swing arm bracket 1111. This method of using an arc-shaped groove and an arc-shaped rotating block to achieve rotation around a virtual axis can be called a virtual axis rotation connection method. That is, the two rotating entities do not directly rotate relative to each other through a solid pin, but are connected by the aforementioned mating structure. This connection method helps to reduce the volume of the main shaft unit and facilitates the miniaturization of the rotating shaft mechanism. Among them, the first arc-shaped rotating block 11211 can be, but is not limited to, a circular arc-shaped rotating block, and the first arc-shaped groove 11111 can be, but is not limited to, a circular arc groove.

[0088] In one specific embodiment, the first arc-shaped rotating block 11211 may include two sub-rotating blocks, namely a first sub-rotating block 11211a and a second sub-rotating block 11211b, which are spaced apart along the length of the rotating shaft mechanism. Correspondingly, the first arc-shaped groove 11111 may also include a first sub-arc-shaped groove (not shown in the figure) and a second sub-arc-shaped groove, which are also spaced apart along the length of the rotating shaft mechanism. The first sub-rotating block 11211a can be accommodated in the first sub-arc-shaped groove and can rotate along the arc surface of the first sub-arc-shaped groove, and the second sub-rotating block 11211b can be accommodated in the second sub-arc-shaped groove and can rotate along the arc surface of the second sub-arc-shaped groove. Through the rotational cooperation between the two sets of sub-rotating blocks and sub-arc-shaped grooves, the motion stability of the first support arm 1122 relative to the base 12 can be effectively improved.

[0089] Of course, in some other embodiments, the first swing arm 1121 and the swing arm bracket 1111 can also be rotatably connected by a pin. In this case, hinge holes can be provided on the first swing arm 1121 and the swing arm bracket 1111 respectively, and the pin can be rotatably set in the hinge holes of both.

[0090] Figure 8 A schematic diagram of the structure of the first housing support 1123 provided in an embodiment of this application. See also... Figures 6 to 8As shown, a first slot 11231 may be provided on the side of the first housing support 1123 facing the first swing arm 1121, and the end of the first swing arm 1121 away from the swing arm support 1111 may be disposed in the first slot 11231. The slot wall of the first slot 11231 may be provided with a hinge hole a, and correspondingly, the end of the first swing arm 1121 away from the swing arm support 1111 may be provided with a hinge hole b. The first swing arm 1121 can be rotatably connected to the first housing support 1123 by rotating a pin disposed in its hinge hole a and the hinge hole b of the first slot 11231.

[0091] Figure 9 A schematic diagram of the structure of the first support arm 1122 provided in an embodiment of this application. See also... Figure 6 and Figure 9 As shown, in this embodiment, the module bracket 111 may further include a damping bracket 1112 and a pin 1113. The damping bracket 1112 and the aforementioned swing arm bracket 1111 may be spaced apart along the length direction of the rotating shaft mechanism. The pin 1113 connects the damping bracket 1112 and the swing arm bracket 1111, and the pin 1113 is also arranged along the length direction of the rotating shaft mechanism. The end of the first support arm 1122 connected to the module bracket 111 is provided with a hinge hole c. The first support arm 1122 can be sleeved on the pin 1113 through the hinge hole c, thereby realizing a rotatable connection with the module bracket 111.

[0092] Please refer to the above. Figure 8 and Figure 9 The first housing support 1123 may also be provided with a first sliding groove 11232, which may be located on the same side of the first housing support 1123. The end of the first support arm 1122 away from the module support 111 is installed in the first sliding groove 11232 and can slide in the first sliding groove 11232. In addition, to prevent the first support arm 1122 from falling out of the first slide groove 11232, a first slide rail 112321 can be provided on the groove wall of the first slide groove 11232. Correspondingly, a first slider 11221 can be provided on the side of the first support arm 1122. The first slider 11221 can be slidably disposed in the first slide rail 112321. In this way, the first support arm 1122 can be limited in the first slide groove 11232, and the first slide rail 112321 can also be used to guide the sliding of the first support arm 1122 in the first slide groove 11232, so as to improve the movement stability of the first support arm 1122.

[0093] Additionally, in some possible embodiments, the number of first support arms 1122 can be one or more, such as... Figure 6The diagram shows a configuration with three first support arms 1122, which can be arranged along the length of the rotating shaft mechanism. Correspondingly, the first housing bracket 1123 can be provided with first sliding grooves 11232 corresponding one-to-one with each of the one or more first support arms 1122, with each first support arm 1122 slidably fitted into its corresponding first sliding groove 11232. By utilizing the cooperation of multiple sets of first support arms 1122 and first sliding grooves 11232, the connection stability between the first support arms 1122 and the first housing bracket 1123 can be effectively improved, further enhancing the motion stability of the first housing bracket 1123.

[0094] Figure 10 This is a partial structural schematic diagram of the spindle unit provided in an embodiment of this application. (Reference) Figure 10 As shown in the figure, and in conjunction with the above description, it can be seen that the first swing arm 1121, the first housing bracket 1123, and the first support arm 1122 can roughly form a crank-connecting rod mechanism. When the rotating shaft mechanism switches from the extended state to the closed state, the first housing bracket 1123 rotates counterclockwise. Based on the rotational connection between the first swing arm 1121 and the first housing bracket 1123, and the sliding connection between the first support arm 1122 and the first housing bracket 1123, the first housing bracket 1123 can drive the first swing arm 1121 and the first support arm 1122 to rotate counterclockwise around the module bracket 111 synchronously. The portion of the first arc-shaped block 11211 of the first swing arm 1121 that is accommodated in the first arc-shaped groove 11111 of the swing arm bracket gradually decreases, while the portion of the first support arm 1122 that is accommodated in the first sliding groove 11232 of the first housing bracket 1123 gradually increases. Conversely, when the rotating shaft mechanism switches from the closed state to the unfolded state, the first housing bracket 1123 rotates clockwise, and drives the first swing arm 1121 and the first support arm 1122 to rotate clockwise around the module bracket simultaneously. The portion of the first arc-shaped block 11211 of the first swing arm 1121 that is accommodated in the first arc-shaped groove 11111 of the swing arm bracket gradually increases, while the portion of the first support arm 1122 that is accommodated in the first sliding groove 11232 of the first housing bracket 1123 gradually decreases.

[0095] The connection relationship between the first housing bracket 1123, the first swing arm 1121, and the first support arm 1122 has been described above. Next, the specific arrangement of the first door panel 1124 will be explained.

[0096] Please refer to this again. Figure 6As shown above, the first door panel 1124 can be rotatably connected to the first housing support 1123 and to the first swing arm 1121. In a specific implementation, the first rotation module 112 may also include a first connecting rod 1125. One end of the first connecting rod 1125 can be rotatably connected to the first swing arm 1121, and the other end of the first connecting rod 1125 can be rotatably connected to the first door panel 1124. In this way, the rotational connection between the first door panel 1124 and the first swing arm 1121 can be achieved through the first connecting rod 1125.

[0097] Combination Figure 2 and Figure 6 As shown, in one specific implementation, the first door panel 1124 may include a first door panel bracket 11241 and a first door panel body 11243. The first door panel body 11243 is disposed on the side of the first door panel bracket 11241 facing the flexible display screen of the electronic device to support the flexible display screen. The first door panel bracket 11241 can be used to support the first door panel body 11243, and the rotatable connection between the first door panel 1124 and the first housing bracket 1123 and the first swing arm 1121 can also be achieved through the first door panel bracket 11241. By designing the first door panel 1124 as a separate structure of the door panel bracket and the door panel body, it helps to reduce the processing difficulty of the first door panel and reduce the manufacturing cost. For example, the first door panel body 11243 can be fixedly connected to the first door panel bracket 11241 by means of screws, riveting, gluing, or welding to improve the assembly efficiency of the pivot mechanism.

[0098] In some embodiments, the first rotating module may further include a third door panel 11242, which may be located on the side of the first door panel 1124 near the module support, so as to jointly support the flexible display screen with the first door panel 1124. The third door panel 11242 may be rotatably connected to the first door panel 1124 and slidably connected to the module support 111, and the third door panel 11242 may rotate relative to the module support 111.

[0099] Furthermore, in this embodiment, the third door panel 11242 of the multiple spindle units can be a separate structure or an integral structure. Similarly, the first door panel body 11243 of the multiple spindle units can also adopt a separate or integral structural design. This application does not impose any restrictions on this. Figure 4 The diagram shows a case where the first door panel body 11243 and the third door panel 11242, which are both integral structures with multiple spindle units, are integrated. This is beneficial for improving the integration of the pivot mechanism and simplifying the assembly difficulty of the pivot mechanism.

[0100] Figure 11 This is a schematic diagram of the structure of the first door panel bracket 11241 provided in an embodiment of this application. Figure 12A schematic diagram of the structure of the first link 1125 provided in an embodiment of this application. See also... Figure 7 , Figure 11 and Figure 12 As shown, the side of the first swing arm 1121 facing the first door panel bracket 11241 may be provided with a first mounting groove 11212, and the side of the first door panel bracket 11241 facing the first swing arm 1121 may be provided with a second mounting groove 112411. One end of the first connecting rod 1125 is rotatably disposed in the first mounting groove 11212, and the other end of the first connecting rod 1125 is rotatably disposed in the second mounting groove 112411. In a specific implementation, the groove wall of the first mounting groove 11212 may be provided with a hinge hole d, and one end of the first connecting rod may be provided with a hinge hole e. The first connecting rod 1125 can be rotatably connected to the first swing arm 1121 by a pin that is rotatably disposed in its hinge hole e and the hinge hole d of the first mounting groove 11212. Similarly, the groove wall of the second mounting groove 112411 may be provided with a hinge hole f, and the other end of the first connecting rod 1125 may be provided with a hinge hole g. The first connecting rod 1125 can be rotatably connected to the first door panel bracket 11241 by rotating the pin that is rotatably set in its hinge hole g and the hinge hole f of the second mounting groove.

[0101] Please refer to the above. Figure 8 and Figure 11 As shown, when the first door panel bracket 11241 is rotatably connected to the first housing bracket 1123, the first housing bracket 1123 may be provided with a third arc-shaped rotating block 11233. Correspondingly, the side of the first door panel bracket 11241 facing the first housing bracket 1123 may be provided with a third arc-shaped groove 112412. The third arc-shaped rotating block 11233 of the first housing bracket 1123 may be accommodated in the third arc-shaped groove 112412 and may rotate along the arc surface of the third arc-shaped groove 112412. In this way, the rotatable connection relationship between the first housing bracket 1123 and the first door panel bracket 11241 can be realized.

[0102] In one specific embodiment, there can be two third arc-shaped rotating blocks 11233, which can be disposed at both ends of the first housing support 1123 along the length of the rotating shaft mechanism. Correspondingly, the first door panel support 11241 can also be provided with two third arc-shaped grooves along the length of the rotating shaft mechanism, and the two third arc-shaped rotating blocks 11233 are respectively rotatably disposed in the corresponding third arc-shaped grooves 112412. Through the rotational cooperation between the third arc-shaped rotating blocks 11233 and the third arc-shaped grooves 112412, the stability of the relative movement between the first door panel support 11241 and the first housing support 1123 can be effectively improved.

[0103] Figure 13 This is a partial structural cross-sectional view of a rotating shaft mechanism provided in an embodiment of this application. (Reference) Figure 13 As shown in the diagram, and based on the above description, it can be seen that, based on the rotational connections between the first swing arm 1121 and the first housing support 1123, between the first housing support 1123 and the first door panel support 11241, between the first door panel support 11241 and the first connecting rod 1125, and between the first connecting rod 1125 and the first swing arm 1121, the first swing arm 1121, the first housing support 1123, the first door panel support 11241, and the first connecting rod 1125 can roughly form a four-bar linkage. When the rotating shaft mechanism switches from the extended state to the closed state, the first housing support 1123 drives the first swing arm 1121 to rotate counterclockwise synchronously. During the rotation, the first swing arm 1121 pulls the first door panel support 11241 through the first connecting rod 1125. Under the constraint of the first connecting rod 1125 and the first housing support 1123, the first door panel support 11241 also rotates counterclockwise relative to the module support 111. Conversely, when the pivot mechanism switches from a closed state to an open state, the first housing support 1123 drives the first swing arm 1121 to rotate clockwise synchronously. During rotation, the first swing arm 1121 pushes the first door panel support 11241 through the first connecting rod 1125. Under the constraint of the first connecting rod 1125 and the first housing support 1123, the first door panel support 11241 also rotates clockwise relative to the module support 111. This four-bar linkage design effectively improves the motion accuracy of the pivot mechanism during opening and closing, improves the stress state of the first door panel support 11241, and thus enhances the overall structural reliability of electronic devices using this pivot mechanism.

[0104] Please refer to this again. Figure 11 As shown, in order to improve the movement stability of the first door panel bracket 11241, in some embodiments, a first protrusion 112413 may be provided on the side of the first door panel bracket 11241 facing away from the flexible display screen. Along the length direction of the rotating shaft mechanism, the first protrusion 112413 may be located on one side of the first support arm 1122, for example, on the side of the first support arm 1122 where the first slider 11221 is not provided (see reference). Figure 9The first support arm 1122 may have a first sliding shaft 11222 on its side. Correspondingly, the first protrusion 112413 facing the first support arm 1122 may have a first rotating groove 1124131. The first sliding shaft 11222 can be accommodated in the first rotating groove 1124131 and can slide along the first rotating groove 1124131. In this way, the first door panel bracket 11241 and the first support arm 1122 can be rotated through the cooperation of the first sliding shaft 11222 and the first rotating groove 1124131. During the opening and closing of the rotating shaft mechanism, the first door panel bracket 11241 can be driven to rotate by the first housing bracket 1123, the first connecting rod 1125 and the first support arm 1122, which helps to further improve the reliability and stability of the movement of the first door panel bracket 11241.

[0105] Figure 14 This is a schematic diagram of the structure of the first door panel 1124 and the third door panel 11242 provided in an embodiment of this application. Figure 15 This is a partial cross-sectional view of the rotating shaft mechanism provided in an embodiment of this application in an intermediate state. (See also...) Figure 14 and Figure 15 As shown, the rotational connection between the third door panel 11242 and the first door panel 1124 can be achieved using a virtual axis. For example, a fifth arc-shaped rotating block 112422 can be provided on the side of the third door panel 11242 facing away from the flexible display screen. Correspondingly, a fifth arc-shaped groove 112431 can be provided on the side of the first door panel body 11243 facing away from the flexible display screen. The fifth arc-shaped block 112422 of the third door panel 11242 can be accommodated within the fifth arc-shaped groove 112431 and can rotate along the arc surface of the fifth arc-shaped groove 112431, thereby achieving a rotational connection between the third door panel 11242 and the first door panel body 11243. Using this connection method, the gap between the third door panel 11242 and the first door panel 1124 due to relative motion is relatively small during the unfolding and closing process of the rotating shaft mechanism, thereby improving the support effect on the flexible display screen.

[0106] Of course, in some other embodiments, the third door panel 11242 and the first door panel 1124 can also be rotatably connected by a pin. In this case, pin holes can be provided in the third door panel 11242 and the first door panel body 11243 respectively, and the pin can be rotatably set in the pin holes of both.

[0107] Figure 16 Another partial structural cross-sectional view of the rotating shaft mechanism provided in the embodiments of this application in an intermediate state. See also... Figure 14 and Figure 16As shown, when the third door panel 11242 is rotatably connected to the swing arm bracket 1111, a first extension wall 112421 can be provided on the side of the third door panel 11242 facing away from the flexible display screen. A first fixed shaft 1124211 is provided on the first extension wall 112421, and the first fixed shaft 1124211 can be arranged along the length direction of the rotating shaft mechanism. Correspondingly, along the length direction of the rotating shaft mechanism, a first track groove 11112 can be provided on one end of the swing arm bracket 1111 near the first rotating module 112. The first fixed shaft 1124211 can be disposed in the first track groove 11112 and can slide along the first track groove 11112. In this way, the rotational connection between the third door panel 11242 and the swing arm bracket 1111 can be achieved through the cooperation of the first fixed shaft 1124211 and the first track groove 11112, that is, the rotational connection between the third door panel 11242 and the module bracket 111 can be achieved.

[0108] As mentioned earlier, the first rotating module 112 and the second rotating module 113 can be respectively disposed on both sides of the module bracket 111. For specific implementation details, please refer to [the relevant documentation]. Figure 6 As shown, the second rotating module 113 may also include a second swing arm 1131, a second support arm 1132, a second housing bracket 1133, a second door panel 1134, and a second connecting rod 1135. The second door panel 1134 can be used to support the flexible display screen and is fixedly connected to it. The second swing arm 1131 and the second support arm 1132 can be disposed on the side of the second door panel 1134 opposite to the flexible display screen. The second swing arm 1131 and the second support arm 1132 are distributed along the length of the rotating shaft mechanism, and both are rotatably connected to the module bracket 111. The second housing bracket 1133 can be located on the side of the second swing arm 1131 and the second support arm 1132 opposite to the second door panel 1134, and can be fixedly connected to the second housing.

[0109] Combination Figure 6 and Figure 10 As shown, similar to the first swing arm 1121, the second swing arm 1131 can also be rotatably connected to the swing arm bracket 1111. In a specific implementation, the end of the second swing arm 1131 used to connect with the swing arm bracket 1111 can be provided with a second arc-shaped rotating block 11311. Correspondingly, the swing arm bracket 1111 can be provided with a second arc-shaped groove 11113, and the second arc-shaped rotating block 11311 can be slidably disposed in the second arc-shaped groove 11113.

[0110] A second slot 11331 may be provided on the side of the second housing bracket 1133 facing the second swing arm 1131, and the end of the second swing arm 1131 away from the swing arm bracket 1111 may be disposed in the second slot 11331. Hinge holes may be provided on the end of the second swing arm 1131 away from the swing arm bracket 1111 and the wall of the second slot 11331, respectively. The second swing arm 1131 can be rotatably connected to the second housing bracket 1133 by rotating a pin disposed in both hinge holes. The second housing bracket 1133 may also be provided with a second sliding groove 11332, which may be located on the same side of the second housing bracket 1133. The end of the second support arm away from the module bracket is installed in the second sliding groove and can slide within the second sliding groove.

[0111] Alternatively, there can be one or more second support arms 1132, and these multiple second support arms 1132 can be arranged along the length of the rotating shaft mechanism. Correspondingly, the second housing bracket 1133 can be provided with second slide grooves 11332 corresponding one-to-one with the one or more second support arms 1132. Each second support arm 1132 is slidably assembled in its corresponding second slide groove 11332, so that the connection stability between the second support arms 1132 and the second housing bracket 1133 is improved through the cooperation of multiple sets of second support arms 1132 and second slide grooves 11332.

[0112] refer to Figure 4 and Figure 6 As shown, the second door panel 1134 can be rotatably connected to the second housing bracket 1133 and to the second swing arm 1131. In a specific implementation, one end of the second connecting rod 1135 can be rotatably connected to the second swing arm 1131, and the other end of the second connecting rod 1135 can be rotatably connected to the second door panel 1134. In this way, the rotatable connection between the second door panel 1134 and the second swing arm 1131 can be achieved through the second connecting rod 1135.

[0113] The second door panel 1134 may include a second door panel bracket 11341 and a second door panel body 11343, wherein the second door panel body 11343 is disposed on the side of the second door panel bracket 11341 facing the flexible display screen of the electronic device, for supporting the flexible display screen. Exemplarily, the fourth sub-board 11343 may be fixedly connected to the second door panel bracket 11341 by means of, but not limited to, screws, riveting, adhesive application, or welding.

[0114] Additionally, the second rotating module may also include a fourth door panel 11342, which may be located on the side of the second door panel 1134 near the module support, to jointly support the flexible display screen with the second door panel 1134. The fourth door panel 11342 may be rotatably connected to the second door panel 1134 and slidably connected to the module support 111, and the fourth door panel 11342 may rotate relative to the module support 111.

[0115] In a specific embodiment, the side of the second swing arm 1131 facing the second door panel bracket 11341 may be provided with a third mounting groove 11312, and the side of the second door panel bracket 11341 facing the second swing arm 1131 may be provided with a fourth mounting groove 113411. One end of the second connecting rod 1135 is rotatably disposed in the third mounting groove 11312, and the other end of the second connecting rod 1135 is rotatably disposed in the fourth mounting groove 113411.

[0116] When the second door panel bracket 11341 is rotatably connected to the second housing bracket 1133, the second housing bracket 1133 may be provided with a fourth arc-shaped rotating block 11333. Correspondingly, the side of the second door panel bracket 11341 facing the second housing bracket 1133 may be provided with a fourth arc-shaped groove 113412. The fourth arc-shaped block 11333 of the second housing bracket 1133 may be slidably disposed in the fourth arc-shaped groove 113412, thereby realizing the rotatable connection between the second housing bracket 1133 and the second door panel bracket 11341.

[0117] In addition, a second protrusion can be provided on the side of the second door panel bracket away from the flexible display screen. Along the length of the rotating shaft mechanism, the second protrusion can be located on one side of the second support arm. A second sliding shaft can be provided on the side of the second support arm facing the second protrusion. Correspondingly, a second rotating groove can be provided on the side of the second protrusion facing the second support arm. The second sliding shaft can be accommodated in the second rotating groove and can slide along the second rotating groove. In this way, the rotational connection between the second door panel bracket and the second support arm can be realized through the cooperation of the second sliding shaft and the second rotating groove.

[0118] Please refer to the above. Figure 15 and Figure 16 As shown, when the fourth door panel 11342 is rotatably connected to the module bracket 111, a second extension wall (not shown in the figure) can be provided on the side of the fourth door panel 11342 facing away from the flexible display screen. A second fixed shaft is provided on the second extension wall, and the second fixed shaft can be arranged along the length direction of the rotating shaft mechanism. Correspondingly, along the length direction of the rotating shaft mechanism, a second track groove 11114 can be provided on one end of the swing arm bracket 1111 near the second rotating module 113. The second fixed shaft can be slidably disposed in the second track groove 11114, thereby realizing the rotatable connection between the fourth door panel 11342 and the module bracket 111.

[0119] In addition, a sixth arc-shaped rotating block 113421 may be provided on the side of the fourth door panel 11342 facing away from the flexible display screen. Correspondingly, a sixth arc-shaped groove 113431 may be provided on the side of the second door panel body 11343 facing away from the flexible display screen. The sixth arc-shaped rotating block 113421 of the fourth door panel 11342 can be slidably disposed in the sixth arc-shaped groove 113431, thereby realizing the rotational connection between the fourth door panel 11342 and the second door panel body 11343.

[0120] After understanding the structure and connection relationship between the first rotating module 112, the second rotating module 113 and the module support 111 provided in the above embodiments of this application, the movement process of the rotating shaft mechanism will be described below.

[0121] First refer to Figure 17 As shown, Figure 17 This is a partial structural diagram of the rotating shaft mechanism provided in the embodiment of this application in the unfolded state. When the rotating shaft mechanism is in the unfolded state, the first rotating module 112 and the second rotating module 113 are located on both sides of the module support 111, and the included angle between them is approximately 180 degrees. At this time, the sides of the first door panel 1124 and the third door panel 11242 that are away from the first housing support 1123, and the sides of the second door panel 1134 and the fourth door panel 11342 that are away from the second housing support 1133 are coplanarly arranged, and the multiple door panels can provide flat support for the flexible display screen.

[0122] refer to Figure 18 As shown, Figure 18This is a partial structural diagram of the rotating shaft mechanism provided in the embodiment of this application in an intermediate state. During the transition from the extended state to the closed state, the first housing support 1123 rotates counterclockwise, causing the first swing arm 1121 and the first support arm 1122 to rotate counterclockwise synchronously. During rotation, the first swing arm 1121 pulls the first door panel 1124 via the first connecting rod 1125. Under the constraint of the first connecting rod 1125 and the first housing support 1123, the first door panel 1124 rotates counterclockwise, causing the end of the first door panel 1124 closest to the module support 111 to face away from the module. As the bracket 111 rotates, the third door panel 11242, driven by the first door panel 1124, also rotates counterclockwise relative to the module bracket 111. At this time, the end of the third door panel 11242 closest to the module bracket 111 gradually forms a certain angle with it, while the end of the third door panel 11242 furthest from the module bracket 111 (i.e., the end closest to the first door panel 1124) rotates towards the module bracket 111, gradually forming an opening with the first door panel 1124. The included angle on one side of the second rotating module; correspondingly, the second housing bracket 1133 rotates clockwise, driving the second swing arm 1131 and the second support arm 1132 to rotate clockwise synchronously. During the rotation, the second swing arm 1131 pulls the second door panel 1134 through the second connecting rod 1135. Under the constraint of the second connecting rod 1135 and the second housing bracket 1133, the second door panel 1134 rotates clockwise, thereby causing the end of the second door panel 1134 near the module bracket 111 to face away from the module bracket 111. As the direction of rotation changes, the fourth door panel 11342, driven by the second door panel 1134, also rotates clockwise relative to the module bracket 111. At this time, the end of the fourth door panel 11342 near the module bracket 111 can gradually form a certain angle with the module bracket 111, and the end of the fourth door panel 11342 away from the module bracket 111 (i.e. the end near the second door panel) can rotate toward the module bracket 111 and gradually form an angle with the second door panel 1134 with an opening facing the first rotating module.

[0123] refer to Figure 19 As shown, Figure 19 This is a partial structural diagram of the rotating shaft mechanism provided in the embodiment of this application in the closed state. The rotating shaft mechanism is... Figure 18 The intermediate state shown Figure 19During the process of changing the closed state shown, the first housing bracket 1123 continues to rotate counterclockwise, and together with the first connecting rod 1125, pulls the first door panel 1124 to rotate counterclockwise. The second housing bracket 1133 continues to rotate clockwise, and together with the second connecting rod 1135, pulls the second door panel 1134 to rotate clockwise, until the first door panel 1124 rotates to the first position and the second door panel 1134 rotates to the second position. At this time, the first housing bracket 1123 and the second housing bracket 1133 are approximately in opposite positions, and the rotating shaft mechanism switches to the closed state. When the pivot mechanism is closed, an angle can be formed between the first door panel 1124 and the second door panel 1134. Correspondingly, a certain angle is also formed between the first door panel 1124 and the third door panel 11242, and between the second door panel 1134 and the fourth door panel 11342. The angle formed by the first door panel 1124 and the third door panel 11242 is opposite to the angle formed by the second door panel 1134 and the fourth door panel 11342. In this way, the first door panel 1124, the third door panel 11242, the second door panel 1134, the fourth door panel 11342, and the module bracket 111 can jointly form a teardrop-shaped screen-accommodating space, thereby meeting the bending requirements of the flexible display screen of electronic devices, reducing the risk of compression or stretching of the flexible display screen, and extending its service life.

[0124] It is understandable that when the rotating shaft mechanism is... Figure 19 The closed state shown Figure 17 When rotated in the unfolded state shown, each component of the first rotating module 112 and each component of the second rotating module 113 can move in the opposite process to that described above, which will not be repeated here.

[0125] Figure 20 This is another structural schematic diagram of the first door panel 1124 and the third door panel 11242 provided in the embodiments of this application. Besides being connected via the aforementioned virtual axis, the first door panel 1124 and the third door panel 11242 can also be connected by referring to... Figure 20 As shown, the connection is achieved using a first flexible member 11244. Utilizing the deformable nature of the first flexible member 11244, the first door panel 1124 and the third door panel 11242 can rotate relative to each other through the deformation of the first flexible member 11244. This allows the first door panel 1124 and the third door panel 11242 to be connected in a parallel and coplanar relationship when the rotating shaft mechanism is in the unfolded state, and also to be connected in a bent relationship at a certain angle when the rotating shaft mechanism is in the closed state, thus meeting the needs of the flexible display screen in different states.

[0126] In one specific implementation, the first flexible member 11244 can be disposed on the side of the first door panel body 11243 and the third door panel 11242 facing the flexible display screen, and the first flexible member can be fixedly connected to the first door panel body 11243 and the third door panel 11242 respectively by adhesive bonding. For example, the first flexible member 11244 may include, but is not limited to, materials such as carbon fiber and Kevlar.

[0127] Figure 21 A schematic diagram of another first door panel 1124 and third door panel 11242 provided for an embodiment of this application. Figure 21 Also shown is an example of a connection between the first door panel 1124 and the third door panel 11242 using a first flexible member 11244. Unlike the previous embodiments, in this embodiment, the first flexible member 11244 can be connected between the first door panel body 11243 and the third door panel 11242. In this case, the first door panel body 11243 and the third door panel 11242 can be a single-piece structure, with the deformable first flexible member 11244 formed by thinning at the connection point.

[0128] Of course, the second door panel and the fourth door panel can also be connected by a second flexible component. Similarly, the second flexible component can be glued to the side of the second door panel and the fourth door panel away from the second door panel bracket, or it can be connected between the second door panel and the fourth door panel. This will not be elaborated further here.

[0129] Figure 22 A schematic diagram of the structure of the first door panel 1124 provided in an embodiment of this application. (See reference...) Figure 22 As shown, in some possible embodiments of this application, the first door panel body and the first door panel bracket can also be an integral structure. When the first door panel 1124 is rotatably connected to the first housing bracket 1123, a third arc-shaped rotating block 11233 (see reference) can be directly provided on the integral first door panel 1124 and the first housing bracket 1123. Figure 6 The first door panel 1124 is rotatably connected to the first swing arm 1121 via a third arc-shaped groove 112412. When the first door panel 1124 is rotatably connected to the first swing arm 1121, a second mounting groove 112411 can be provided on the side of the first door panel 1124 facing away from the flexible display screen. One end of the first connecting rod 1125 is hinged to the second mounting groove 112411, and the other end is hinged to the first mounting groove 11212 of the first swing arm 1121, thereby rotatably connecting the first door panel 1124 to the first swing arm 1121 via the first connecting rod 1125. This design simplifies the structure of the first door panel 1124, thereby simplifying the overall structure of the rotating shaft mechanism and reducing its assembly difficulty.

[0130] Similarly, the second door panel body and the second door panel bracket can also be an integral structure. In this case, when the second door panel is rotatably connected to the second housing bracket, a fourth arc-shaped groove that cooperates with the fourth arc-shaped rotating block of the second housing bracket can be directly provided on the integral second door panel. When the second door panel is rotatably connected to the second swing arm, a fourth mounting groove can be provided on the side of the second door panel away from the flexible display screen, and one end of the second connecting rod is hinged in the fourth mounting groove, and the other end is hinged in the third mounting groove of the second swing arm, thereby rotatably connecting the second door panel through the second connecting rod.

[0131] Figure 23 This is a partial structural diagram of another rotating shaft mechanism provided in an embodiment of this application. Figure 24 for Figure 23 A cross-sectional view of the rotating shaft mechanism shown. See also... Figure 23 and Figure 24 As shown, in this embodiment, the structure and arrangement of the first rotating module and the second rotating module are largely the same as in the aforementioned embodiments, and will not be described in detail here. Unlike the aforementioned embodiments, in this embodiment, the base 12 is no longer located on the side of the rotating shaft mechanism away from its supporting surface, but is located between the first door panel 1124 and the second door panel 1134. Furthermore, when the first rotating module includes a third door panel 11242 and the second rotating module includes a fourth door panel 11342, the base 12 can be located between the third door panel 11242 and the fourth door panel 11342, and the base 12 can be located on the side of the module support 111 facing the flexible display screen. When the rotating shaft mechanism is in the unfolded state, the side of the base 12 away from the module support 111 can be coplanar with the side of the first door panel 1124 and the third door panel 11242 away from the first swing arm 1121, and coplanar with the side of the second door panel 1134 and the fourth door panel 11342 away from the second swing arm 1131. In the unfolded state, the surfaces of the base 12, the first door panel 1124, the third door panel 11242, the second door panel 1134, and the fourth door panel 11342 are all located on the same plane. At this time, the base 12 can be regarded as the fifth sub-plate of the rotating shaft mechanism, which can support the flexible display screen together with the other four sub-plates, thereby providing a better support effect for the flexible display screen and further improving the reliability of the flexible display screen.

[0132] Please refer to this again. Figure 6 In this embodiment of the application, in order to better realize the opening and closing of the rotating shaft mechanism 1, the rotating shaft mechanism 1 may also be provided with a damping component 114 that can provide damping force to the first rotating module 112 and the second rotating module 113, so that the first rotating module 112 and the second rotating module 113 can rotate stably under the action of damping force, avoid accidental opening and closing of electronic devices, and realize the two housings hovering at a set position.

[0133] refer to Figure 25 As shown, Figure 25 This is a partial structural diagram of the rotating shaft mechanism provided in an embodiment of this application. The damping assembly 114 may include an elastic element 1141 and an integrated cam 1142, and along the length direction of the rotating shaft mechanism, the integrated cam 1142 may be located between the elastic element and the first support arm 1122 and the second support arm 1132. The end of the first support arm 1122 facing the integrated cam 1142 may be provided with a first cam surface, the end of the second support arm 1132 facing the integrated cam 1142 may be provided with a second cam surface, the end of the integrated cam 1142 facing the first support arm 1122 may be provided with a third cam surface, and the end of the integrated cam 1142 facing the second support arm 1132 may be provided with a fourth cam surface. Under the action of the elastic element 1141, the first cam surface abuts against the third cam surface, and the second cam surface abuts against the cam surface.

[0134] In this embodiment, each cam surface may include multiple protrusions and recesses. When the inclined surfaces of the protrusions of two cam surfaces come into contact, a damping force is generated between the two cam surfaces to prevent them from continuing to rotate relative to each other. Based on this, during the rotation of the two support arms around their corresponding pins, the damping component 114 can provide a certain damping force to each of the two support arms. This damping force can be transmitted to the first housing support through the first support arm 1122 and to the second housing support through the second support arm 1132. Thus, the two housing supports act on the two housings of the electronic device respectively, reducing the risk of accidental opening and closing of the electronic device and enabling the two housings to hover at a set position. In addition, by setting the damping component, the user can obtain a more obvious operating feel during the opening or closing of the electronic device, which is beneficial to improving the user experience.

[0135] Continue to refer to Figure 25 The rotating shaft mechanism may also include components disposed on the damping bracket 1112 and the swing arm bracket 1111 (see reference). Figure 6 One or more intermediate shafts 1114 are provided between the first support arm 1122 and the second support arm 1132. These intermediate shafts 1114 may be located between the two pins 1113 hinged to the first support arm 1122 and the second support arm 1132, and the intermediate shafts 1114 may also extend along the length direction of the rotating shaft mechanism. The integrated cam 1142 may be provided with multiple through holes, through which the integrated cam 1142 may be sleeved on the pins 1113 and the intermediate shafts 1114. The elastic element 1141 may include multiple springs arranged side by side, each spring also being sleeved on the pins 1113 and the intermediate shafts 1114 respectively, to prevent the springs from shifting when elastic deformation occurs.

[0136] Furthermore, the number of damping components 114 can be multiple, for example in... Figure 23In the embodiment shown, when there are three first support arms 1122 and three second support arms 1132, the damping assembly 114 can be two sets. The two sets of damping assemblies 114 are respectively disposed between two adjacent first support arms 1122 (or two adjacent second support arms 1132) to provide sufficient damping force for the first rotating module and the second rotating module, thereby further improving the opening and closing reliability of the electronic device.

[0137] In addition to the structures described above, in some embodiments of this application, the rotating shaft mechanism may also include a synchronization component. Please continue to refer to... Figure 24 The synchronization component 115 may include a first drive gear 1151 disposed on the first support arm 1122 and a second drive gear 1152 disposed on the second support arm 1132, with the first drive gear 1151 and the second drive gear 1152 being connected in a transmission manner. In this way, during the rotation of one support arm around the module bracket, it can drive the other support arm to rotate synchronously around the module bracket in opposite or opposite directions, and the two support arms rotate through the same angle.

[0138] refer to Figure 26 As shown, Figure 26 for Figure 25 The diagram shows a cross-sectional view of the rotating shaft mechanism at point AA. In this embodiment, the synchronization component may further include a driven gear 1153, which may be disposed between two driving gears. Furthermore, there may be an even number of driven gears 1153, and adjacent driven gears 1153 mesh with each other and with driving gears, thereby enabling the two driving gears to rotate synchronously through the even number of driven gears 1153. In specific implementations, the driven gears 1153 may be fitted onto the intermediate shaft 1114 to improve the motion stability of the synchronization component.

[0139] As the support arm rotates around the module bracket, it drives the housing bracket on the same side to rotate at the same angle. This allows for synchronous rotation of the two housing brackets as the two support arms rotate. Furthermore, since the housing brackets can be fixedly connected to the electronic device's housing, the synchronous rotation of the two housing brackets enables the synchronous rotation of the two housings of the electronic device. This avoids applying instantaneous forces to the flexible display screen fixed to the two housings, thus improving the reliability of the flexible display screen.

[0140] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
