[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on July 20, 2023, with application number 202310898042.0 and application name “Hinge Mechanism and Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of electronic equipment, and in particular to a rotating shaft mechanism and electronic equipment. Background Art

[0004] The angle of a foldable electronic device in its flattened state is crucial to its overall refinement. Current foldable electronic devices typically control the flattened angle by adjusting the thickness of the stop surfaces between rotating mating components, such as the thickness of the stop surfaces between the arc arm and the main shaft. However, the dimensions and tolerances of the rotating mating components vary widely, resulting in low reliability for controlling the flattened angle. Foldable electronic devices are prone to over-bending, which can damage the flexible display.

[0005] Summary of the Invention

[0006] The present application provides a hinge mechanism and an electronic device to solve the problem of low reliability of angle control in the flattened state of a foldable electronic device.

[0007] In a first aspect, the present application provides a hinge mechanism that can be used in a foldable electronic device. The hinge mechanism is arranged relative to the foldable portion of the flexible display screen of the electronic device, and the electronic device is unfolded or closed by the hinge mechanism. The hinge mechanism may include a main shaft, a first shell bracket, a second shell bracket, and a flattening stop mechanism. The first shell bracket and the second shell bracket may be arranged on opposite sides of the main shaft. The flattening stop mechanism may include a first stop structure and a second stop structure. The first stop structure may include a first connecting rod and a first stop block. The first connecting rod may be rotatably connected to the main shaft and the first connecting rod may be slidably connected to the first shell bracket. The first stop block may be fixedly connected to the first shell bracket, and the first stop block is arranged relative to the first connecting rod. The second stop structure may include a second connecting rod and a second stop block. The second connecting rod may be rotatably connected to the main shaft and the second connecting rod may be slidably connected to the second shell bracket. The second stop block may be fixedly connected to the second shell bracket, and the second stop block is arranged relative to the second connecting rod. The first connecting rod and the second connecting rod can be connected in a transmission manner. When the electronic device is unfolded or closed, the first shell bracket and the second shell bracket can rotate synchronously away from or towards each other relative to the main axis, the first connecting rod and the second connecting rod can rotate synchronously away from or towards each other relative to the main axis, and the first connecting rod can slide relative to the first shell bracket, and the second connecting rod can slide relative to the second shell bracket; in the process of the electronic device being unfolded to a flattened state, the first connecting rod can slide in a direction away from the first shell bracket, and the second connecting rod can slide in a direction away from the second shell bracket, and when the electronic device is unfolded to a flattened state, the first connecting rod can abut against the first stop block, and the second connecting rod can abut against the second stop block to prevent the first connecting rod and the second connecting rod from sliding in a direction away from the first shell bracket and the second shell bracket respectively.

[0008] In the technical solution provided in the present application, during the process of the electronic device being unfolded to the flattened state, the first connecting rod slides in a direction away from the first shell bracket, and when the electronic device is unfolded to the flattened state, the first connecting rod abuts against the first stop block, limiting the first connecting rod from continuing to slide relative to the first shell bracket, thereby limiting the first shell bracket from continuing to rotate relative to the main axis in the unfolding direction. Similarly, the second connecting rod slides in a direction away from the second shell bracket, and when the electronic device is unfolded to the flattened state, the second connecting rod abuts against the second stop block, limiting the second connecting rod from continuing to slide relative to the second shell bracket, thereby limiting the second shell bracket from continuing to rotate relative to the main axis in the unfolding direction. The rotation of the first shell bracket and the second shell bracket in the flattened state are both limited, so the flattening angle of the electronic device can be reliably controlled, the electronic device is not prone to over-folding, and the flexible display screen of the electronic device is not easily damaged.

[0009] In one specific embodiment, the first housing support may be provided with a first chute, the first chute may extend in a direction away from the main axis, the first connecting rod may be slidably disposed in the first chute, and when the electronic device is unfolded or closed, the first connecting rod may slide relative to the first housing support in a direction away from or approaching the first housing support, thereby achieving a sliding connection between the first connecting rod and the first housing support. The second housing support may be provided with a second chute, the second chute may extend in a direction away from the main axis, the second connecting rod may be slidably disposed in the second chute, and when the electronic device is unfolded or closed, the second connecting rod may slide relative to the second housing support in a direction away from or approaching the second housing support, thereby achieving a sliding connection between the second connecting rod and the second housing support.

[0010] When the sliding groove is specifically set, a first avoidance groove can be set in the first sliding groove, and the first avoidance groove can be set on the side wall of the first sliding groove along a direction perpendicular to the rotation axis of the rotating shaft mechanism. The first avoidance groove can provide avoidance space for the possible rotation of the first connecting rod relative to the first shell bracket during the sliding process of the first connecting rod relative to the first shell bracket, thereby avoiding interference with the sliding of the first connecting rod. A second avoidance groove can be set in the second sliding groove, and the second avoidance groove can be set on the side wall of the second sliding groove along a direction perpendicular to the rotation axis of the rotating shaft mechanism. The second avoidance groove can provide avoidance space for the possible rotation of the second connecting rod relative to the second shell bracket during the sliding process of the second connecting rod relative to the second shell bracket, thereby avoiding interference with the sliding of the second connecting rod.

[0011] In a specific feasible implementation scheme, the first slide groove may have a first opening along a direction perpendicular to the rotation axis of the rotating shaft mechanism, the first stop block may cover the first opening, and a portion of the first connecting rod may be located between the first stop block and the first shell bracket. The first stop block and the first shell bracket clamp a portion of the first connecting rod, so that the first connecting rod can be stably maintained in the first slide groove, and the first connecting rod can be prevented from shaking in a direction perpendicular to the rotation axis of the rotating shaft mechanism, thereby improving the stability and smoothness of the sliding of the first connecting rod. The second slide groove may have a second opening along a direction perpendicular to the rotation axis of the rotating shaft mechanism, the second stop block may cover the second opening, and a portion of the second connecting rod may be located between the second stop block and the second shell bracket. The second stop block and the second shell bracket clamp a portion of the second connecting rod, so that the second connecting rod can be stably maintained in the second slide groove, and the second connecting rod can be prevented from shaking in a direction perpendicular to the rotation axis of the rotating shaft mechanism, thereby improving the stability and smoothness of the sliding of the second connecting rod.

[0012] In a specific feasible embodiment, a first recessed portion and a second recessed portion may be provided in the first chute, and the first recessed portion and the second recessed portion may be respectively provided on two side walls of the first chute that are opposite to each other along the rotation axis of the rotating shaft mechanism, and the first connecting rod may be slidably connected in the first recessed portion and the second recessed portion. The first recessed portion and the second recessed portion may provide a slideway for the sliding of the first connecting rod in the first chute, thereby improving the sliding stability of the first connecting rod. A third recessed portion and a fourth recessed portion may be provided in the second chute, and the third recessed portion and the fourth recessed portion may be respectively provided on two side walls of the second chute that are opposite to each other along the rotation axis of the rotating shaft mechanism, and the second connecting rod may be slidably connected in the third recessed portion and the fourth recessed portion. The third recessed portion and the fourth recessed portion may provide a slideway for the sliding of the second connecting rod in the second chute, thereby improving the sliding stability of the second connecting rod.

[0013] In the specific configuration of the connecting rod, the first connecting rod can be provided with a first sliding portion and a second sliding portion, respectively, on either side of the first connecting rod along the axis of rotation of the rotating shaft mechanism. The first sliding portion and the second sliding portion can be respectively slidably connected to the sidewalls of the first chute along a direction perpendicular to the axis of rotation of the rotating shaft mechanism. When the first connecting rod slides, the first sliding portion and the second sliding portion serve as the portions of the first connecting rod that contact the first chute and the first stop block. The first sliding portion and the second sliding portion are respectively provided on either side of the first connecting rod along the axis of rotation of the rotating shaft mechanism, which can improve the stability of the overall sliding of the first connecting rod. The thickness of the portion of the first connecting rod other than the first sliding portion and the second sliding portion can be appropriately thin, which can reduce the overall weight of the first connecting rod and can also allow the first connecting rod to rotate relative to the first housing support during its sliding relative to the first housing support. The second connecting rod can be provided with a third sliding portion and a fourth sliding portion, respectively, on either side of the second connecting rod along the axis of rotation of the rotating shaft mechanism. The third sliding portion and the fourth sliding portion can be respectively slidably connected to the sidewalls of the second chute along a direction perpendicular to the axis of rotation of the rotating shaft mechanism. When the second connecting rod slides, the third sliding part and the fourth sliding part serve as the parts of the second connecting rod that contact the second sliding groove and the second stop block. The third sliding part and the fourth sliding part are respectively arranged on both sides of the second connecting rod along the axial direction of rotation of the rotating shaft mechanism, which can improve the overall sliding stability of the second connecting rod, and the thickness of the second connecting rod other than the third sliding part and the fourth sliding part can be appropriately thinner, which can reduce the overall weight of the second connecting rod and also allow the second connecting rod to rotate relative to the second shell bracket during the sliding process of the second connecting rod relative to the second shell bracket.

[0014] In a specific feasible embodiment, the end of the first sliding part away from the main shaft may have a first curved surface, and the end of the second sliding part away from the main shaft may have a second curved surface. When the first connecting rod slides, the first curved surface contacts the first slide groove and the first stop block, and the second curved surface also contacts the first slide groove and the first stop block, which can ensure the accuracy and smoothness of the sliding movement of the first connecting rod. The end of the third sliding part away from the main shaft may have a third curved surface, and the end of the fourth sliding part away from the main shaft may have a fourth curved surface. When the second connecting rod slides, the third curved surface contacts the second slide groove and the second stop block, and the fourth curved surface also contacts the second slide groove and the second stop block, which can ensure the accuracy and smoothness of the sliding movement of the second connecting rod.

The first sliding portion and the second sliding portion are respectively wedge-shaped structures, which not only ensure the precision and smoothness of the sliding movement of the first connecting rod, but also improve the wear resistance of the sliding portions, thereby increasing the sliding stability of the first connecting rod and the service life of the first connecting rod. The cross-sectional dimensions of the third sliding portion along the axis of rotation of the rotating shaft mechanism decrease from the end away from the main shaft to the end closer to the main shaft, and the cross-sectional dimensions of the fourth sliding portion along the axis of rotation of the rotating shaft mechanism decrease from the end away from the main shaft to the end closer to the main shaft. The third sliding portion and the fourth sliding portion are respectively wedge-shaped structures, which not only ensure the precision and smoothness of the sliding movement of the second connecting rod, but also improve the wear resistance of the sliding portions, thereby increasing the sliding stability of the second connecting rod and the service life of the second connecting rod.

[0016] In one specific embodiment, the first connecting rod may be provided with a first stop groove along the sliding direction, and a first stop protrusion may be provided on a surface of the first stop block facing the first connecting rod, the first stop protrusion may extend into the first stop groove. When the electronic device is unfolded to a flat state, the first connecting rod abuts the first stop block, including: the end of the first stop groove away from the main shaft abuts the first stop protrusion. This can limit the first connecting rod from sliding further away from the first housing bracket, that is, limit the first housing bracket and the first connecting rod from sliding further relative to each other in the unfolding direction, thereby limiting the first housing bracket from rotating further relative to the main shaft in the unfolding direction. The second connecting rod may be provided with a second stop groove along the sliding direction, and a second stop protrusion may be provided on a surface of the second stop block facing the second connecting rod, the second stop protrusion may extend into the second stop groove. When the electronic device is unfolded to a flat state, the second connecting rod abuts the second stop block, including: the end of the second stop groove away from the main shaft abuts the second stop protrusion. The second connecting rod can be restricted from sliding further away from the second housing bracket, that is, the second housing bracket and the second connecting rod are restricted from sliding further relative to each other in the expansion direction, thereby restricting the second housing bracket from rotating further relative to the main shaft in the expansion direction.

[0017] In a specific embodiment, the first housing bracket can be provided with a first mounting groove and a second mounting groove, and the first mounting groove and the second mounting groove can be respectively located on either side of the first connecting rod along the rotation axis of the rotating shaft mechanism, and the two ends of the first stop block along the rotation axis of the rotating shaft mechanism can be respectively fixedly connected to the first mounting groove and the second mounting groove. This can achieve a fixed connection between the first stop block and the first housing bracket. The second housing bracket can be provided with a third mounting groove and a fourth mounting groove, and the third mounting groove and the fourth mounting groove can be respectively located on either side of the second connecting rod along the rotation axis of the rotating shaft mechanism, and the two ends of the second stop block along the rotation axis of the rotating shaft mechanism can be respectively fixedly connected to the third mounting groove and the fourth mounting groove. This can achieve a fixed connection between the second stop block and the second housing bracket.

[0018] In a specific embodiment, a first gear portion may be provided at one end of the first connecting rod rotatably connected to the main shaft, and a second gear portion may be provided at one end of the second connecting rod rotatably connected to the main shaft. The first gear portion and the second gear portion may be transmission-connected to each other so that the first connecting rod and the second connecting rod can rotate synchronously in opposite directions or toward each other relative to the main shaft. Synchronous rotation of the first connecting rod and the second connecting rod relative to the main shaft can be achieved.

[0019] In one specific embodiment, the main shaft may be provided with a synchronous gear set, which may be located between the first connecting rod and the second connecting rod. The first gear portion and the second gear portion may be transmission-connected via the synchronous gear set. The synchronous gear set may include an even number of transmission gears transmission-connected in sequence. This allows for synchronized rotation of the first gear portion and the second gear portion, thereby achieving synchronized rotation of the first connecting rod and the second connecting rod.

[0020] In a second aspect, the present application further provides an electronic device, which may include a first housing, a second housing, a flexible display, and a hinge mechanism as described in any of the possible implementations of the first aspect.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all explained with reference to the accompanying drawings as examples, but changes may be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings in the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0034] The following description sets forth specific details to facilitate understanding of the present application. However, the embodiments of the present application can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotations of the embodiments of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0035] For ease of understanding, the application scenarios of the hinge mechanism involved in the embodiments of the present application are first described. The hinge mechanism provided in the embodiments of the present application can be adapted for electronic devices, such as mobile terminals such as mobile phones, tablet computers, or laptop computers. As a possible application scenario, the hinge mechanism provided in the embodiments of the present application can be adapted for foldable electronic devices as a component of the hinge module of the foldable electronic device.

[0036] Foldable electronic devices typically include a flexible display, a hinge module, and a housing. The housing comprises a first housing and a second housing, movably connected by the hinge module. When the foldable electronic device is opened or closed, the first and second housings rotate relative to each other, and the hinge module provides a damping force, causing the flexible display to flex.

[0037] First, refer to Figures 1 and 2. Figure 1 shows an exploded structural diagram of the rotating shaft mechanism provided in an embodiment of the present application, and Figure 2 shows an assembly structural diagram of the rotating shaft mechanism provided in an embodiment of the present application. As shown in Figures 1 and 2, the rotating shaft mechanism provided in an embodiment of the present application may include a main shaft 1, a first shell bracket 2, a second shell bracket 3, and a flattening stop mechanism. The first shell bracket 2 and the second shell bracket 3 may be arranged on opposite sides of the main shaft 1. The flattening stop mechanism includes two stop structures, which are a first stop structure 10 and a second stop structure 20, respectively. The first stop structure 10 and the second stop structure 20 may be arranged on opposite sides of the main shaft 1.

[0038] In the embodiment of the present application, the first stop structure 10 may include a first connecting rod 101 and a first stop block 102. The first connecting rod 101 may be rotatably connected to the main shaft 1, and the rotation axis of the first connecting rod 101 may be parallel to the rotation axis of the rotating shaft mechanism. The first connecting rod 101 may also be slidably connected to the first housing support 2. The first stop block 102 may be fixedly connected to the first housing support 2, for example, the first stop block 102 may be welded to the first housing support 2. The first stop block 102 is disposed opposite the first connecting rod 101, specifically, the first stop block 102 is disposed corresponding to the position of the first connecting rod 101.

[0039] Similar to the first stop structure 10, the second stop structure 20 may include a second connecting rod 201 and a second stop block 202. The second connecting rod 201 is rotationally connected to the main shaft 1, and the second connecting rod 201 is slidingly connected to the second shell bracket 3. The second stop block 202 is fixedly connected to the second shell bracket 3, and the second stop block 202 is arranged opposite to the second connecting rod 201.

[0040] Referring to Figures 3 and 4, Figure 3 shows a schematic structural diagram of the rotating shaft mechanism provided in an embodiment of the present application in a closed state, and Figure 4 shows a schematic structural diagram of the rotating shaft mechanism provided in an embodiment of the present application in a flattened state. As shown in Figures 3 and 4, during specific implementation, the first connecting rod 101 can be transmission-connected to the second connecting rod 201. When the electronic device is unfolded or closed, the first housing bracket 2 and the second housing bracket 3 can rotate synchronously in opposite directions or toward each other relative to the main shaft 1, which can drive the first connecting rod 101 and the second connecting rod 201 to rotate synchronously in opposite directions or toward each other relative to the main shaft 1, and the first connecting rod 101 can slide relative to the first housing bracket 2, and the second connecting rod 201 can slide relative to the second housing bracket 3. During the process of unfolding the electronic device to the flattened state, the first connecting rod 101 slides in a direction away from the first housing support 2, and when the electronic device is unfolded to the flattened state, the first connecting rod 101 abuts against the first stop block 102, limiting the first connecting rod 101 from continuing to slide relative to the first housing support 2, that is, preventing the first connecting rod 101 from continuing to slide in the direction away from the first housing support 2, thereby limiting the first housing support 2 from continuing to rotate relative to the main shaft 1 in the unfolding direction. Similarly, the second connecting rod 201 slides in a direction away from the second housing support 3, and when the electronic device is unfolded to the flattened state, the second connecting rod 201 abuts against the second stop block 202, limiting the second connecting rod 201 from continuing to slide relative to the second housing support 3, that is, preventing the second connecting rod 201 from continuing to slide in the direction away from the second housing support 3, thereby limiting the second housing support 3 from continuing to rotate relative to the main shaft 1 in the unfolding direction. The rotation of the first housing support 2 and the second housing support 3 in the unfolded state is limited, so that the flattened angle of the electronic device can be reliably controlled, the electronic device is not prone to over-bending, and the flexible display screen of the electronic device is not easily damaged. Moreover, during the assembly process, the relative position of the first stop block 102 on the first shell bracket 2 and the relative position of the second stop block 202 on the second shell bracket 3 can be adjusted to achieve the adjustment of the flattened state angle of the first shell bracket 2 and the second shell bracket 3, that is, to adjust the flattened state angle of the electronic device, so as to facilitate the fitting tolerance between the covering components and easily achieve the ideal flattened state angle.

[0041] For ease of description, in the following embodiments of the present application, the specific configuration of the first stop structure 10 is mainly used as an example to illustrate the rotating shaft mechanism, and the configuration of the second stop structure 20 can refer to the configuration of the first stop structure 10. It is understood that the design of the second stop structure 20 can be completely consistent with that of the first stop structure 10, or it can only refer to the components and connection relationships included in the first stop structure 10. Other parameters can be adaptively adjusted and do not require complete consistency.

[0042] Referring to Figures 5 and 6, Figure 5 shows a schematic diagram of the assembly structure of a partial structure of the rotating shaft mechanism provided in an embodiment of the present application, and Figure 6 shows a schematic diagram of the structure of the first shell bracket of the rotating shaft mechanism provided in an embodiment of the present application. Different from Figure 2, the first stop block 102 and the second stop block 202 in Figure 2 are hidden in Figure 5. As shown in Figure 5, in an embodiment of the present application, the first shell bracket 2 is provided with a first slide groove 21, and the first slide groove 21 extends in a direction away from the main axis 1. Taking the rotating shaft mechanism applied to an inward-folding electronic device as an example, specifically, the first slide groove 21 can be located on the side of the first shell bracket 2 facing the flexible display screen, and when the first shell bracket 2 is formed by a mold, the first slide groove 21 can be formed together by the mold. The first connecting rod 101 can be slidably set in the first slide groove 21 to realize the sliding connection between the first connecting rod 101 and the first shell bracket 2. When the electronic device is unfolded or closed, the first shell bracket 2 rotates relative to the main shaft 1 in a direction away from or approaching the main shaft 1, driving the first connecting rod 101 to rotate relative to the main shaft 1 in a direction away from or approaching the main shaft 1. At the same time, the first connecting rod 101 slides relative to the first shell bracket 2 in a direction away from or approaching the first shell bracket 2.

[0043] As shown in FIG6 , a first avoidance groove 211 may be provided in the first chute 21. The first avoidance groove 211 may be provided on a sidewall of the first chute 21 perpendicular to the axis of rotation of the rotating shaft mechanism. In conjunction with FIG5 , the first avoidance groove 211 may provide a space for the first connecting rod 101 to avoid rotation relative to the first housing support 2 during the sliding process of the first connecting rod 101 relative to the first housing support 2, thereby preventing interference with the sliding of the first connecting rod 101.

[0044] As shown in Figures 2 and 6, the first slide groove 21 can have a first opening in a direction perpendicular to the rotation axis of the hinge mechanism. Taking the hinge mechanism applied to an inward-folding electronic device as an example, the first opening can face the flexible display screen. The first stop block 102 can cover the first opening. Part of the first connecting rod 101 can be located between the first stop block 102 and the first shell bracket 2, or part of the first connecting rod 101 can be located in the accommodating space formed by the first stop block 102 and the first slide groove 21. The first stop block 102 and the first shell bracket 2 clamp part of the first connecting rod 101. The first stop block 102 can keep the first connecting rod 101 stably in the first slide groove 21 and prevent the first connecting rod 101 from shaking in a direction perpendicular to the rotation axis of the hinge mechanism, thereby improving the stability and smoothness of the sliding of the first connecting rod 101. In this specific implementation, the first stop block 102 has the function of limiting the first connecting rod 101 from continuing to slide relative to the first shell bracket 2 when the electronic device is unfolded to a flat state. At the same time, the first stop block 102 also has the function of clamping part of the first connecting rod 101 together with the first shell bracket 2 to prevent the first connecting rod 101 from shaking in a direction perpendicular to the rotation axis of the hinge mechanism.

[0045] Referring to Figure 7 , Figure 7 illustrates a schematic structural diagram of the first stopper of the rotating shaft mechanism provided in an embodiment of the present application. As shown in conjunction with Figures 5 and 7 , a third slot 1021 can be provided on the side of the first stopper 102 facing the first connecting rod 101. The third slot 1021 can be aligned with the first slot 21 along a direction perpendicular to the rotational axis of the rotating shaft mechanism. Together, the third slot 1021 and the first slot 21 form a storage space to accommodate a portion of the first connecting rod 101. The third slot 1021 can contribute to a portion of the depth of the storage space along a direction perpendicular to the rotational axis of the rotating shaft mechanism, thereby allowing the depth of the first slot 21 to be relatively shallow, which helps maintain the structural strength of the first housing support 2.

[0046] Referring to Figures 8 and 9 , Figure 8 shows a schematic diagram of the structure of a rotating shaft mechanism according to another embodiment of the present application, and Figure 9 shows a partial schematic diagram of the structure of a rotating shaft mechanism according to another embodiment of the present application. Unlike Figure 5 , the structure of the first chute 21 in Figure 8 has been modified. Unlike Figure 8 , the first stopper 102 and the second stopper 202 in Figure 8 are omitted. As shown in Figure 8 , the first chute 21 may be provided with a first recessed portion 212 and a second recessed portion 213. The first recessed portion 212 and the second recessed portion 213 may be respectively provided on two opposing side walls of the first chute 21 along the axis of rotation of the rotating shaft mechanism. The first connecting rod 101 may be slidably connected within the first recessed portion 212 and the second recessed portion 213. The first recessed portion 212 and the second recessed portion 213 provide a sliding path for the first connecting rod 101 to slide within the first chute 21, thereby improving the sliding stability of the first connecting rod 101. Specifically, the first recessed portion 212 and the second recessed portion 213 may be formed by cutting grooves within the first chute 21. In this specific implementation, the first stop block 102 has the function of limiting the first connecting rod 101 from continuing to slide relative to the first shell bracket 2 when the electronic device is unfolded to a flat state, and the first recessed portion 212 and the second recessed portion 213 have the function of limiting the first connecting rod 101 from shaking in a direction perpendicular to the rotation axis of the hinge mechanism.

[0047] Referring to Figure 10, Figure 10 shows a schematic structural diagram of the first connecting rod of the rotating shaft mechanism provided in an embodiment of the present application. In conjunction with Figures 5, 8, and 10, one end of the first connecting rod 101 that is rotatably connected to the main shaft 1 may be provided with a first mounting hole 1014. The first connecting rod 101 may be rotatably connected to the main shaft 1 via a connecting member such as a pin disposed within the first mounting hole 1014. The first connecting rod 101 may be provided with a first sliding portion 1011 and a second sliding portion 1012 on either side of the rotating shaft mechanism. The first sliding portion 1011 and the second sliding portion 1012 may be respectively slidably connected to the sidewalls of the first chute 21 along a direction perpendicular to the rotating shaft mechanism. When the first connecting rod 101 slides, the first sliding part 1011 and the second sliding part 1012 serve as the parts of the first connecting rod 101 that contact the first sliding groove 21 and the first stop block 102. The first sliding part 1011 and the second sliding part 1012 are respectively arranged on both sides of the first connecting rod 101 along the axial direction of rotation of the rotating shaft mechanism, which can improve the overall sliding stability of the first connecting rod 101, and the thickness of the part of the first connecting rod 101 other than the first sliding part 1011 and the second sliding part 1012 can be appropriately thinner, which can reduce the overall weight of the first connecting rod 101 and allow the first connecting rod 101 to rotate relative to the first shell bracket 2 during the sliding process of the first connecting rod 101 relative to the first shell bracket 2. Specifically, when the first recessed portion 212 and the second recessed portion 213 are provided in the first sliding groove 21, the first sliding portion 1011 and the second sliding portion 1012 can be respectively located in the first recessed portion 212 and the second recessed portion 213, and the first sliding portion 1011 can be slidably connected to the side wall of the first recessed portion 212 along a direction perpendicular to the rotation axis of the rotating shaft mechanism, and the second sliding portion 1012 can be slidably connected to the side wall of the second recessed portion 213 along a direction perpendicular to the rotation axis of the rotating shaft mechanism, which can further improve the overall sliding stability of the first connecting rod 101.

[0048] In an embodiment of the present application, the end of the first sliding portion 1011 away from the main shaft 1 may have a first curved surface 10111, and the axial direction of the first curved surface 10111 may be parallel to the rotation axis of the rotating shaft mechanism. The end of the second sliding portion 1012 away from the main shaft 1 may have a second curved surface 10121, and the axial direction of the second curved surface 10121 may also be parallel to the rotation axis of the rotating shaft mechanism. When the first connecting rod 101 slides, the first curved surface 10111 contacts the first slide groove 21 and the first stop block 102, and the second curved surface 10121 also contacts the first slide groove 21 and the first stop block 102, which can ensure the accuracy and smoothness of the sliding movement of the first connecting rod 101. In a specific implementation, the first curved surface 10111 and the second curved surface 10121 can extend along the rotation axis of the rotating shaft mechanism and connect to form a complete curved surface, which is convenient for molding.

[0049] In some possible implementations, the first sliding portion 1011 can be a cylindrical structure, and the first curved surface 10111 is a portion of the cylindrical surface of the first sliding portion 1011. Similarly, the second sliding portion 1012 can also be a cylindrical structure, and the second curved surface 10121 is a portion of the cylindrical surface of the second sliding portion 1012. In other possible implementations, the cross-sectional dimensions of the first sliding portion 1011 along the rotational axis of the rotating shaft mechanism decrease from the end away from the main shaft 1 to the end closer to the main shaft 1. This can be understood as the first sliding portion 1011 being a wedge-shaped structure, and the two ends of the wedge-shaped structure can each have a curved surface. The cross-sectional dimensions of the second sliding portion 1012 along the rotational axis of the rotating shaft mechanism decrease from the end away from the main shaft 1 to the end closer to the main shaft 1. Similarly, this can be understood as the second sliding portion 1012 being a wedge-shaped structure, and the two ends of the wedge-shaped structure can each have a curved surface. The sliding portion of the wedge structure can not only ensure the accuracy and smoothness of the sliding movement of the first connecting rod 101, but also improve the wear resistance of the sliding portion, thereby improving the sliding stability of the first connecting rod 101 and the service life of the first connecting rod 101.

[0050] As shown in FIG7 , the first connecting rod 101 may be provided with a first stop groove 1013 along its sliding direction. A first stop protrusion 1022 may be provided on the side of the first stop block 102 facing the first connecting rod 101. During actual assembly, the first stop protrusion 1022 extends into the first stop groove 1013. When the electronic device is unfolded to a flat state, the first connecting rod 101 abuts against the first stop block 102. Specifically, the end of the first stop groove 1013 away from the main shaft 1 abuts against the first stop protrusion 1022, restricting the first connecting rod 101 from sliding further away from the first housing bracket 2, that is, restricting the first housing bracket 2 and the first connecting rod 101 from sliding further relative to each other in the unfolding direction, thereby restricting the first housing bracket 2 from rotating further relative to the main shaft 1 in the unfolding direction. In a specific implementation, the first stop groove 1013 may be a circumferentially closed groove or a circumferentially open semi-open groove, which can play the above-mentioned restrictive role.

[0051] Referring again to Figures 2 and 6 , the first housing bracket 2 can be provided with a first mounting groove 22 and a second mounting groove 23. For example, in the case of an inward-folding electronic device employing the hinge mechanism, the first mounting groove 22 and the second mounting groove 23 can be located on the side of the first housing bracket 2 facing the flexible display screen, and the first mounting groove 22 and the second mounting groove 23 can be located on either side of the first connecting rod 101 along the axis of rotation of the hinge mechanism. The first stop block 102 can be fixedly connected to the first mounting groove 22 and the second mounting groove 23 at both ends along the axis of rotation of the hinge mechanism, thereby achieving a fixed connection between the first stop block 102 and the first housing bracket 2.

[0052] As shown in FIG. 7 , in a specific implementation, the first stop block 102 may be provided with a first adjustment slot 1023 to facilitate adjustment of the relative position of the first stop block 102 and the first housing bracket 2 during assembly and to appropriately reduce the weight of the first stop block 102 .

[0053] As mentioned above, the second shell bracket 3 and the first shell bracket 2 can be arranged on opposite sides of the main shaft 1. In specific implementation, referring to Figure 5 again, the second shell bracket 3 is provided with a second slide groove 31, and the second slide groove 31 extends in a direction away from the main shaft 1. The second connecting rod 201 is slidably arranged in the second slide groove 31. When the electronic device is unfolded or closed, the second connecting rod 201 slides relative to the second shell bracket 3 in a direction away from or approaching the second shell bracket 3.

[0054] In this embodiment of the present application, a second escape groove is provided within the second chute 31. The second escape groove is provided on a sidewall of the second chute 31 perpendicular to the axis of rotation of the shaft mechanism. As shown in FIG2 , the second chute 31 has a second opening perpendicular to the axis of rotation of the shaft mechanism. The second stop block 202 covers the second opening, and a portion of the second connecting rod 201 is positioned between the second stop block 202 and the second housing bracket 3 .

[0055] In a specific implementation, a fourth slide groove is provided on the side of the second stop block 202 facing the second connecting rod 201. The fourth slide groove and the second slide groove 31 are aligned in a direction perpendicular to the axial direction of rotation of the rotating shaft mechanism. The fourth slide groove and the second slide groove 31 together form an accommodating space to accommodate the second connecting rod 201.

[0056] In the embodiment of the present application, in combination with Figure 8, a third recess 312 and a fourth recess 313 are provided in the second slide groove 31, and the third recess 312 and the fourth recess 313 are respectively provided on two side walls of the second slide groove 31 that are opposite to each other along the rotation axis of the rotating shaft mechanism, and the second connecting rod 201 is slidably connected in the third recess 312 and the fourth recess 313.

[0057] In the embodiment of the present application, the second connecting rod 201 is provided with a third sliding portion and a fourth sliding portion on both sides along the rotation axis of the rotating shaft mechanism, respectively. The third sliding portion and the fourth sliding portion are respectively slidably connected to the side walls of the second sliding groove 31 along a direction perpendicular to the rotation axis of the rotating shaft mechanism. The third sliding portion has a third curved surface at the end away from the main shaft 1, and the fourth sliding portion has a fourth curved surface at the end away from the main shaft 1. The cross-sectional dimensions of the third sliding portion along the rotation axis of the rotating shaft mechanism decrease from the end away from the main shaft 1 to the end close to the main shaft 1, which can be understood as the third sliding portion being a wedge-shaped structure. The cross-sectional dimensions of the fourth sliding portion along the rotation axis of the rotating shaft mechanism decrease from the end away from the main shaft 1 to the end close to the main shaft 1, which can be understood as the fourth sliding portion being a wedge-shaped structure.

[0058] In an embodiment of the present application, a second stop groove is provided on the second connecting rod 201 along the sliding direction, and a second stop protrusion is provided on the side of the second stop block 202 facing the second connecting rod 201. The second stop protrusion extends into the second stop groove. When the electronic device is unfolded to a flattened state, the end of the second stop groove away from the main shaft 1 abuts against the second stop protrusion.

[0059] In an embodiment of the present application, the second shell bracket 3 is provided with a third mounting groove and a fourth mounting groove, and the third mounting groove and the fourth mounting groove are respectively located on both sides of the second connecting rod 201 along the rotation axis of the rotating shaft mechanism, and the second stop block 202 is respectively fixedly connected in the third mounting groove and the fourth mounting groove at both ends along the rotation axis of the rotating shaft mechanism.

[0060] It can be understood that some of the features in the above embodiments are described by taking the application of the hinge mechanism to an electronic device that folds inward as an example. In actual application, the hinge mechanism can also be applied to an electronic device that folds outward. In this case, the setting position, orientation, etc. of this part of the features can be adaptively adjusted according to the change in the folding direction of the electronic device.

[0061] 5 and 10 , a first gear portion 1015 may be provided at one end of the first connecting rod 101 rotatably connected to the main shaft 1, and a second gear portion 2015 may be provided at one end of the second connecting rod 201 rotatably connected to the main shaft 1. The first gear portion 1015 and the second gear portion 2015 are in transmission connection, so that the first connecting rod 101 and the second connecting rod 201 rotate synchronously in opposite directions or toward each other relative to the main shaft 1. Specifically, the first gear portion 1015 may include a plurality of first tooth structures arranged around the rotation axis of the first connecting rod 101, and the second gear portion 2015 may include a plurality of second tooth structures arranged around the rotation axis of the second connecting rod 201. The first gear portion 1015 and the second gear portion 2015 are engaged with each other through the plurality of first tooth structures and the plurality of second tooth structures, so that the first gear portion 1015 and the second gear portion 2015 rotate synchronously.

[0062] In a specific embodiment, the main shaft 1 can be provided with a synchronous gear set, which is located between the first connecting rod 101 and the second connecting rod 201. The first gear portion 1015 and the second gear portion 2015 are transmission-connected via the synchronous gear set. The synchronous gear set can include an even number of transmission gears that are sequentially transmission-connected. For example, the synchronous gear set includes two transmission gears that are rotationally connected, achieving synchronous rotation of the first gear portion 1015 and the second gear portion 2015, thereby achieving synchronous rotation of the first connecting rod 101 and the second connecting rod 201. Specifically, the axial direction of the transmission gears can be parallel to the rotational axis of the shaft mechanism.

Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in this application should be covered by the protection scope of the present application.
