[0002] The angle of a foldable electronic device in the flattened state is very important for the refinement of the whole device. Current foldable electronic devices usually achieve flattened state angle control by rotating the thickness of the stop surface between the mating parts, for example, by the thickness of the arc arm of the rotating shaft and the stop surface of the main shaft. However, the size and matching tolerance of the rotating mating parts are large, and the reliability of the flattened state angle control is low. Foldable electronic devices are prone to over-folding, which can easily damage the flexible display screen of the foldable electronic device. Summary of the invention

[0003] The present application provides a hinge mechanism and an electronic device to solve the problem of low reliability of angle control in a flattened state of a foldable electronic device.

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, and 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 transmission. When the electronic device is unfolded or closed, the first shell bracket and the second shell bracket can rotate synchronously away from or towards the main axis, the first connecting rod and the second connecting rod can rotate synchronously away from or towards 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.

[0005] In the technical solution provided in the present application, during the process of the electronic device being unfolded to a 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 along 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 along the unfolding direction.

[0037] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. However, the example implementation can be implemented in various forms and should not be construed as being limited to the implementations 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 described 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 of the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0038] The following description sets forth specific details to facilitate understanding of the present application, but the embodiments of the present application can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the embodiments of the present application. Therefore, the present application is not limited to the specific implementation methods disclosed below.

[0039] For ease of understanding, the application scenario of the hinge mechanism involved in the embodiment of the present application is first described. The hinge mechanism provided in the embodiment of the present application can be adapted to 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 embodiment of the present application can be adapted to foldable electronic devices as a component of the hinge module of the foldable electronic device.

[0040] A foldable electronic device generally includes a flexible display screen, a hinge module, a housing and other structural parts. The housing includes a first housing and a second housing movably connected by the hinge module. When the foldable electronic device is opened or closed, the first housing and the second housing rotate relative to each other, the hinge module provides a damping force, and the flexible display screen bends.

[0041] First refer to Figure 1 and Figure 2 , Figure 1 The exploded structural diagram of the rotating shaft mechanism provided in the embodiment of the present application is shown. Figure 2 FIG. 1 shows a schematic diagram of the assembly structure of the rotating shaft mechanism provided in an embodiment of the present application. Figure 1 and Figure 2As shown, the shaft mechanism provided in the embodiment of the present application may include a main shaft 1, a first housing support 2, a second housing support 3 and a flattening stop mechanism. The first housing support 2 and the second housing support 3 may be disposed 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 disposed on opposite sides of the main shaft 1.

[0042] 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 bracket 2. The first stop block 102 may be fixedly connected to the first housing bracket 2, for example, the first stop block 102 may be welded to the first housing bracket 2. The first stop block 102 is arranged opposite to the first connecting rod 101, and specifically, the first stop block 102 is arranged corresponding to the position of the first connecting rod 101.

[0043] 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.

[0044] Reference Figure 3 and Figure 4 , Figure 3 The structure diagram of the rotating shaft mechanism provided in the embodiment of the present application in the closed state is shown. Figure 4 FIG. 1 shows a schematic diagram of the structure of the rotating shaft mechanism provided in an embodiment of the present application in a flattened state. Figure 3 and Figure 4As shown, in a specific implementation, the first connecting rod 101 can be connected to the second connecting rod 201 in a transmission manner. When the electronic device is unfolded or closed, the first shell bracket 2 and the second shell bracket 3 can rotate synchronously in opposite directions or in opposite directions relative to the main axis 1, which can drive the first connecting rod 101 and the second connecting rod 201 to rotate synchronously in opposite directions or in opposite directions relative to the main axis 1, and the first connecting rod 101 can slide relative to the first shell bracket 2, and the second connecting rod 201 can slide relative to the second shell 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 shell bracket 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 shell bracket 2, that is, preventing the first connecting rod 101 from continuing to slide in a direction away from the first shell bracket 2, thereby limiting the first shell bracket 2 from continuing to rotate relative to the main axis 1 along the unfolding direction. Similarly, the second connecting rod 201 slides in a direction away from the second shell bracket 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 shell bracket 3, that is, preventing the second connecting rod 201 from continuing to slide in a direction away from the second shell bracket 3, thereby limiting the second shell bracket 3 from continuing to rotate relative to the main axis 1 along the unfolding direction. The rotation of the first shell bracket 2 and the second shell bracket 3 in the unfolded state is limited, so that the flattened state 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 prone to damage. Furthermore, 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 adjustment of the flattened angle of the first shell bracket 2 and the second shell bracket 3, that is, to adjust the flattened angle of the electronic device, so as to cover the fitting tolerance between the components and easily achieve an ideal flattened angle.

[0045] For the convenience 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 shaft mechanism, and the second stop structure 20 side can be configured with reference to the first stop structure 10 side. It can be understood that the design of the second stop structure 20 can be completely consistent with the first stop structure 10, or only refer to the components and connection relationships included in the first stop structure 10, and other parameters can be adaptively adjusted and do not require complete consistency.

[0046] Reference Figure 5 and Figure 6 , Figure 5 The schematic diagram of the assembly structure of the partial structure of the rotating shaft mechanism provided in the embodiment of the present application is shown. Figure 6 The structure diagram of the first housing support of the rotating shaft mechanism provided in the embodiment of the present application is shown. Figure 2 , Figure 5 Hidden in the Figure 2 The first stop block 102 and the second stop block 202. Figure 5 As shown, in the 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 application of the hinge mechanism to an electronic device that folds inward 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 arranged in the first slide groove 21 to achieve a 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 axis 1 in a direction away from or close to the main axis 1, driving the first connecting rod 101 to rotate relative to the main axis 1 in a direction away from or close to the main axis 1, and at the same time, the first connecting rod 101 slides relative to the first shell bracket 2 in a direction away from or close to the first shell bracket 2.

[0047] like Figure 6 As shown, a first avoidance groove 211 may be provided in the first slide groove 21, and the first avoidance groove 211 may be provided on a side wall of the first slide groove 21 along a direction perpendicular to the rotation axis of the shaft mechanism. Figure 5 As shown, the first avoidance groove 211 can provide an avoidance space for the possible rotation of the first connecting rod 101 relative to the first housing bracket 2 during the sliding process of the first connecting rod 101 relative to the first housing bracket 2, thereby preventing the sliding of the first connecting rod 101 from being interfered.

[0048] Combination Figure 2 and Figure 6 As shown, the first slide groove 21 may have a first opening in a direction perpendicular to the rotation axis of the hinge mechanism. Taking the hinge mechanism applied to an inwardly folded electronic device as an example, the first opening may face the flexible display screen. The first stop block 102 may cover the first opening. Part of the first connecting rod 101 may be located between the first stop block 102 and the first shell bracket 2, or part of the first connecting rod 101 may be located in the accommodation 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.

[0049] Reference Figure 7 , Figure 7 The schematic diagram of the structure of the first stop block of the rotating shaft mechanism provided in the embodiment of the present application is shown. Figure 5 and Figure 7 As shown, a third slide groove 1021 may be provided on one side of the first stop block 102 facing the first connecting rod 101, and the third slide groove 1021 and the first slide groove 21 may be aligned and arranged in a direction perpendicular to the rotation axis of the shaft mechanism, and the third slide groove 1021 and the first slide groove 21 together form an accommodation space to accommodate part of the first connecting rod 101. The third slide groove 1021 may share a portion of the depth of the accommodation space in a direction perpendicular to the rotation axis of the shaft mechanism, so that the depth of the first slide groove 21 may be shallow, which is beneficial to maintaining the structural strength of the first housing bracket 2.

The first connecting rod 101 may be slidably connected in the first recessed portion 212 and the second recessed portion 213. The first recessed portion 212 and the second recessed portion 213 may provide a slideway for the sliding of the first connecting rod 101 in the first chute 21, and may improve the sliding stability of the first connecting rod 101. Specifically, the first recessed portion 212 and the second recessed portion 213 may be formed in the first chute 21 by digging grooves. 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 housing bracket 2 when the electronic device is unfolded to a flattened 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 shaft mechanism.

[0051] Reference Fig.10 , Fig.10 The structure diagram of the first connecting rod of the rotating shaft mechanism provided in the embodiment of the present application is shown. Figure 5 , Figure 8 and Fig.10As shown, one end of the first connecting rod 101 rotatably connected to the main shaft 1 may be provided with a first mounting hole 1014, and the first connecting rod 101 may be rotatably connected to the main shaft 1 by a connecting member such as a pin shaft penetrating through 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 both sides along the rotation axis of the rotating shaft mechanism, respectively, and the first sliding portion 1011 and the second sliding portion 1012 may be slidably connected to the side wall of the first sliding groove 21 along a direction perpendicular to the rotation axis of 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 first connecting rod 101 except 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, 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 axial direction of rotation of the 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 axial direction of rotation of the shaft mechanism, which can further improve the overall sliding stability of the first connecting rod 101.

[0052] In the embodiment of the present application, the end of the first sliding part 1011 away from the main shaft 1 may have a first arcuate surface 10111, and the axial direction of the first arcuate surface 10111 may be parallel to the rotation axis of the shaft mechanism, and the end of the second sliding part 1012 away from the main shaft 1 may have a second arcuate surface 10121, and the axial direction of the second arcuate surface 10121 may also be parallel to the rotation axis of the shaft mechanism. When the first connecting rod 101 slides, the first arcuate surface 10111 contacts the first slide groove 21 and the first stop block 102, and the second arcuate 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 specific implementation, the first arcuate surface 10111 and the second arcuate surface 10121 can extend along the rotation axis of the shaft mechanism and connect to form a complete arcuate surface, which is convenient for molding.

[0053] In some possible specific implementations, the first sliding portion 1011 may be a cylindrical structure, and the first arcuate surface 10111 is a part of the cylindrical surface of the first sliding portion 1011. Similarly, the second sliding portion 1012 may also be a cylindrical structure, and the second arcuate surface 10121 is a part of the cylindrical surface of the second sliding portion 1012. In other possible specific implementations, the cross-sectional size of the first sliding portion 1011 along the axial direction of rotation of the shaft mechanism decreases from the end away from the main shaft 1 to the end close to the main shaft 1. It can be understood that the first sliding portion 1011 is a wedge-shaped structure, and the two ends of the wedge-shaped structure can respectively have arcuate surfaces. The cross-sectional size of the second sliding portion 1012 along the axial direction of rotation of the shaft mechanism decreases from the end away from the main shaft 1 to the end close to the main shaft 1. Similarly, it can be understood that the second sliding portion 1012 is a wedge-shaped structure, and the two ends of the wedge-shaped structure can also respectively have arcuate surfaces. The sliding portion of the wedge-shaped 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.

The first stop block 102 may be provided with a first stop protrusion 1022 on one side 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 flattened 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. During specific implementation, the first stop groove 1013 may be a circumferentially closed groove, or a circumferentially open semi-open groove, which may play the above-mentioned limiting role.

[0055] Refer again Figure 2 and Figure 6 As shown, the first housing bracket 2 may be provided with a first mounting groove 22 and a second mounting groove 23. Taking the case where the hinge mechanism is applied to an inwardly folded electronic device as an example, the first mounting groove 22 and the second mounting groove 23 may 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 may be located on both sides of the first connecting rod 101 along the rotation axis of the hinge mechanism. The two ends of the first stop block 102 along the rotation axis of the hinge mechanism may be fixedly connected to the first mounting groove 22 and the second mounting groove 23, respectively, to achieve a fixed connection between the first stop block 102 and the first housing bracket 2.

[0056] like Figure 7 As shown, 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 .

Figure 5 As shown, 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 axis 1. The second connecting rod 201 is slidably set 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 close to the second shell bracket 3.

[0059] In a specific implementation, a fourth slide groove is provided on a side of the second stop block 202 facing the second connecting rod 201 , and the fourth slide groove is aligned with the second slide groove 31 in a direction perpendicular to the axial direction of rotation of the shaft mechanism, and the fourth slide groove and the second slide groove 31 together form an accommodating space to accommodate the second connecting rod 201 .

[0060] In the embodiment of the present application, Figure 8 As shown, a third recessed portion 312 and a fourth recessed portion 313 are provided in the second slide groove 31. The third recessed portion 312 and the fourth recessed portion 313 are respectively provided on two side walls of the second slide groove 31 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 recessed portion 312 and the fourth recessed portion 313.

[0061] In the embodiment of the present application, the second connecting rod 201 is provided with a third sliding part and a fourth sliding part on both sides along the rotation axis of the rotating shaft mechanism, respectively, and the third sliding part and the fourth sliding part are respectively connected to the second sliding groove 31 in a sliding manner along the side wall in a direction perpendicular to the rotation axis of the rotating shaft mechanism. The end of the third sliding part away from the main shaft 1 has a third arcuate surface, and the end of the fourth sliding part away from the main shaft 1 has a fourth arcuate surface. The cross-sectional size of the third sliding part along the rotation axis of the rotating shaft mechanism decreases 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 part being a wedge-shaped structure. The cross-sectional size of the fourth sliding part along the rotation axis of the rotating shaft mechanism decreases 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 part being a wedge-shaped structure.

[0064] 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 of the folding direction of the electronic device.
