Description

Technical Field

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

[0002] Mobile phones, tablets, and other electronic devices have become indispensable technological products in people's lives, studies, and entertainment. Currently, foldable electronic devices feature flexible displays that are easy to carry when folded. When unfolded, these displays offer a larger display area, making foldable electronic devices increasingly popular with consumers.

[0003] In related technologies, foldable electronic devices typically utilize hinge mechanisms to enable flexible displays to unfold or fold. However, traditional hinge mechanisms usually require gear structures to achieve synchronous rotation, but gear transmission schemes occupy a large amount of space, which is not conducive to improving the compactness of the hinge mechanism. Summary of the Invention

[0004] This disclosure provides a hinge mechanism and a foldable electronic device. The hinge mechanism can switch between an unfolded state and a folded state, and occupies little space, which helps to improve the compactness of the hinge mechanism and realize the thinness and lightness of the foldable electronic device.

[0005] The technical solution is as follows:

[0006] According to a first aspect of the present disclosure, a hinge mechanism is provided, including a base assembly, a load-bearing assembly, a first link assembly, a second link assembly, a first rotating member, a second rotating member, a first linkage member, and a second linkage member. The base assembly includes a first side portion and a second side portion disposed along its width direction. The load-bearing assembly includes a first connecting member disposed near the first side portion and a second connecting member disposed near the second side portion. The first link assembly is disposed between the first side portion and the first connecting member, and is rotatably connected to the first connecting member. The second link assembly is disposed between the second side portion and the second connecting member, and is rotatably connected to the second connecting member. The first rotating member is rotatably connected to the first side portion and slidably connected to the first connecting member. The second rotating member is rotatably connected to the second side portion and slidably connected to the second connecting member. The first linkage member includes a first connecting portion, a second connecting portion, and a first limiting structure disposed between the first connecting portion and the second connecting portion. The first connecting portion is rotatably connected to the second rotating member, and the second connecting portion is rotatably connected to the second link assembly. The first limiting structure engages with the base frame assembly to restrict the movement of the first linkage member relative to the base frame assembly within a preset area. The second linkage member includes a third connecting portion, a fourth connecting portion, and a second limiting structure disposed between the third and fourth connecting portions. The third connecting portion is rotatably connected to the second rotating member, and the fourth connecting portion is rotatably connected to the first link assembly. The second limiting structure engages with the base frame assembly to restrict the movement of the second linkage member relative to the base frame assembly within a preset area.

[0007] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0008] During the assembly of this hinge mechanism, the first rotating member is rotatably connected to the first side portion. The first linkage member is assembled onto the base frame assembly via the first limiting structure and is rotatably connected to the first rotating member via the first connecting part. The second connecting part is rotatably connected to the second link assembly. The first rotating member and the second link assembly are then assembled onto the base frame assembly via the first linkage member, allowing the first rotating member to drive the second link assembly to move. The second linkage member is assembled onto the base frame assembly via the second limiting structure and is rotatably connected to the first link assembly via the third connecting part and the fourth connecting part. This assembles the second rotating member and the first link assembly onto the base frame assembly, allowing the second rotating member to drive the first link assembly to move via the second linkage member. Then, the first connecting member is also assembled onto the first side portion of the base frame assembly via a sliding connection with the first rotating member and a rotatable connection with the first link assembly. Similarly, the second connecting member is also assembled onto the second side portion of the base frame assembly via a sliding connection with the second rotating member and a rotatable connection with the second link assembly, allowing both the first and second connecting members to rotate relative to the base frame assembly.

[0009] Specifically, the first connecting member rotates relative to the base frame assembly via the first link assembly, thus restricting its rotational trajectory. When the first rotating member rotates, the first connecting member rotates along with it, and due to the restriction imposed by the first link assembly, it also slides relative to the rotating member. In other words, the first connecting member is assembled onto the base frame assembly via the first rotating member and the first link assembly, enabling it to move relative to the base frame assembly along a predetermined trajectory. Similarly, the second connecting member is assembled onto the base frame assembly via the second rotating member and the second link assembly, enabling it to move relative to the base frame assembly along a predetermined trajectory.

[0010] For example, during the folding process of the hinge mechanism, the first connecting member rotates relative to the base frame assembly along a predetermined trajectory, causing the first rotating member to rotate. Under the constraint of the first link assembly, the first connecting member slides away from the first rotating member, moving it away from the base frame assembly to create more clearance space. Similarly, the second connecting member rotates relative to the base frame assembly along a predetermined trajectory, causing the second rotating member to rotate. Under the constraint of the second link assembly, the second connecting member slides away from the second rotating member, moving it away from the base frame assembly to create more clearance space.

[0011] For example, during the unfolding of the hinge mechanism, the first connecting member rotates along a predetermined trajectory relative to the base frame assembly, causing the first rotating member to rotate. Under the constraint of the first link assembly, the first connecting member can slide towards the first rotating member, bringing it closer to the base frame assembly to cooperate with it and form a support structure. Similarly, the second connecting member rotates along a predetermined trajectory relative to the base frame assembly, causing the second rotating member to rotate. Under the constraint of the second link assembly, the second connecting member can slide towards the second rotating member, bringing it closer to the base frame assembly to cooperate with it and form a support structure.

[0012] During the rotation of the first rotating member, it can also drive the first linkage member to move within a preset area, thereby pulling the second linkage assembly through the second connecting part, which in turn drives the second connecting member and the second rotating member on the second side to move, achieving synchronous movement of the first connecting member and the second rotating member, and synchronous rotation of the first rotating member and the second rotating member. During the rotation of the second rotating member, it can also drive the second linkage member to move within a preset area, thereby pulling the first linkage assembly through the fourth connecting part, which in turn drives the first connecting member and the first rotating member on the first side to move, achieving synchronous movement of the first connecting member and the second connecting member, and synchronous rotation of the first rotating member and the second rotating member. In this way, the synchronous movement of the first and second connecting members on both sides of the base frame assembly is achieved through two linkage members. Compared to a gear synchronization structure, this method occupies less space, improves the compactness of the hinge mechanism, and is beneficial for achieving a thinner and lighter foldable electronic device.

[0043] According to a second aspect of the present disclosure, a hinge mechanism is provided, including a base frame assembly, a load-bearing assembly, a third link assembly, a fourth link assembly, a third rotating member, a fourth rotating member, and a third linkage member. The base frame assembly includes a first side portion and a second side portion spaced apart from the first side portion along the width direction of the base frame assembly. The load-bearing assembly includes a third connecting member disposed near the first side portion and a fourth connecting member disposed near the second side portion.

The fifth connecting portion is rotatably connected to the third rotating member, and the sixth connecting portion is rotatably connected to the fourth link assembly. The third limiting structure cooperates with the base frame assembly to limit the movement of the third linkage component relative to the base frame assembly within a preset area.

[0044] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0045] During the assembly of this hinge mechanism, the third rotating member is rotatably connected to the first side. The third linkage member is assembled onto the base frame assembly via the third limiting structure and is rotatably connected to the third rotating member via the fifth connecting part. The sixth connecting part is rotatably connected to the fourth link assembly. The third linkage member then assembles the third rotating member and the fourth link assembly onto the base frame assembly, allowing the third rotating member to drive the fourth link assembly to move. The fourth rotating member and the third link assembly are then assembled onto the base frame assembly. The third connecting member is then slidably connected to the third rotating member and rotatably connected to the third link assembly, and is also assembled onto the first side of the base frame assembly. Similarly, the fourth connecting member is slidably connected to the fourth rotating member and rotatably connected to the fourth link assembly, and is also assembled onto the second side of the base frame assembly, allowing the third and fourth connecting members to rotate relative to the base frame assembly.

[0046] Specifically, the third connecting member rotates relative to the base frame assembly via the third link assembly, thus restricting its rotational trajectory. When the third rotating member rotates, the third connecting member follows its rotation, and due to the restriction imposed by the third link assembly, it also slides relative to the rotating member. In other words, the third connecting member is assembled onto the base frame assembly via the third rotating member and the third link assembly, enabling it to move relative to the base frame assembly along a predetermined trajectory. Similarly, the fourth connecting member is assembled onto the base frame assembly via the fourth rotating member and the fourth link assembly, enabling it to move relative to the base frame assembly along a predetermined trajectory.

[0047] For example, during the folding process of the hinge mechanism, the third connecting member rotates relative to the base frame assembly along a predetermined trajectory, causing the third rotating member to rotate. Under the constraint of the third link assembly, the third connecting member slides away from the third rotating member, moving it away from the base frame assembly to create more clearance space. Similarly, the fourth connecting member rotates relative to the base frame assembly along a predetermined trajectory, causing the fourth rotating member to rotate. Under the constraint of the fourth link assembly, the fourth connecting member can slide away from the fourth rotating member, moving it away from the base frame assembly to create more clearance space.

[0048] For example, during the unfolding of the hinge mechanism, the third connecting member rotates along a predetermined trajectory relative to the base frame assembly, causing the third rotating member to rotate. Under the constraint of the third link assembly, the third connecting member can slide towards the third rotating member, bringing it closer to the base frame assembly to cooperate with it and form a support structure. Similarly, the fourth connecting member rotates along a predetermined trajectory relative to the base frame assembly, causing the fourth rotating member to rotate. Under the constraint of the fourth link assembly, the fourth connecting member can slide towards the fourth rotating member, bringing it closer to the base frame assembly to cooperate with it and form a support structure.

[0049] During the rotation of the third rotating component, it can also drive the third linkage component to move within a preset area, which in turn pulls the fourth linkage assembly through the sixth connecting part, thereby driving the fourth connecting component and the fourth rotating component on the second side to move, achieving synchronous movement of the third and fourth connecting components and synchronous rotation of the third and fourth rotating components. In this way, the third linkage component can achieve synchronous movement of the third and fourth connecting components. Compared with the gear synchronization structure, it occupies less space, which can improve the compactness of the hinge mechanism and help to achieve the thinness and lightness of foldable electronic devices.

[0050] The technical solution of this disclosure will be further explained below:

[0051] In one embodiment, the third rotating member is rotatably connected to the first side and has a fifth rotating axis, the third rotating member is rotatably connected to the fifth connecting part and has a sixth rotating axis, and the fifth rotating axis and the sixth rotating axis are not coaxial.

[0052] And / or, the third link assembly is also drive-connected to the third rotating member, and the fourth link assembly is also drive-connected to the fourth rotating member.

[0053] And / or, when the hinge mechanism is in the deployed state, the load-bearing component and the base frame component cooperate to form a support structure. When the hinge mechanism is in the folded state, the load-bearing component and the base frame component intersect at an angle to create clearance space. The hinge mechanism can drive the third and fourth connecting components to move synchronously via the third linkage, thereby switching the hinge mechanism between the deployed and folded states.

[0070] The second linkage assembly also includes an eleventh link and a twelfth link.

[0071] According to a third aspect of the present disclosure, a hinge mechanism is provided, including a base frame assembly, a load-bearing assembly, a fifth link assembly, a sixth link assembly, a fifth rotating member, a sixth rotating member, and a fourth linkage member. The base frame assembly includes a first side portion and a second side portion disposed along its width direction. The load-bearing assembly includes a fifth connecting member disposed near the first side portion and a sixth connecting member disposed near the second side portion. The fifth link assembly is disposed between the first side portion and the fifth connecting member, and is rotatably connected to both the base frame assembly and the fifth connecting member. The sixth link assembly is disposed between the second side portion and the sixth connecting member, and is rotatably connected to both the base frame assembly and the sixth connecting member. The fifth rotating member is rotatably connected to the first side portion and slidably connected to the fifth connecting member. The sixth rotating member is rotatably connected to the second side portion and slidably connected to the sixth connecting member. The fourth linkage member includes a seventh connecting portion, an eighth connecting portion, and a fourth limiting structure disposed between the seventh connecting portion and the eighth connecting portion. The seventh connecting portion is rotatably connected to the fifth rotating member, and the eighth connecting portion is rotatably connected to the sixth link assembly. The fourth limiting structure cooperates with the base frame assembly to limit the movement of the fourth linkage component relative to the base frame assembly within a preset area.

[0072] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0073] During the assembly of this hinge mechanism, the fifth rotating member and the fifth link assembly are rotatably connected to the first side, and the sixth rotating member and the sixth link assembly are rotatably connected to the second side. The fourth linkage member is assembled onto the base frame assembly via the fourth limiting structure and is rotatably connected to the fifth rotating member via the seventh connecting part and to the sixth link assembly via the eighth connecting part. This allows the fifth rotating member and the sixth link assembly to be assembled onto the base frame assembly via the fourth linkage member, enabling the fifth rotating member to drive the sixth link assembly to move, or vice versa. Then, the fifth connecting member is also assembled onto the first side of the base frame assembly via a sliding connection with the fifth rotating member and a rotatable connection with the fifth link assembly. Similarly, the sixth connecting member is also assembled onto the second side of the base frame assembly via a sliding connection with the sixth rotating member and a rotatable connection with the sixth link assembly, allowing the fifth and sixth connecting members to rotate relative to the base frame assembly.

[0074] Specifically, the fifth connecting member rotates relative to the base frame assembly via the fifth link assembly, thus restricting its rotational trajectory. When the fifth rotating member rotates, the fifth connecting member follows it, and due to the restriction imposed by the fifth link assembly, it also slides relative to the fifth rotating member. In other words, the fifth connecting member is assembled onto the base frame assembly via the fifth rotating member and the fifth link assembly, enabling it to move relative to the base frame assembly along a predetermined trajectory. Similarly, the sixth connecting member is assembled onto the base frame assembly via the sixth rotating member and the sixth link assembly, enabling it to move relative to the base frame assembly along a predetermined trajectory.

[0075] For example, during the folding process of the hinge mechanism, the fifth connecting member rotates relative to the base frame assembly along a predetermined trajectory, causing the fifth rotating member to rotate. Under the constraint of the fifth link assembly, the fifth connecting member slides away from the fifth rotating member, moving it away from the base frame assembly to create more clearance space. Similarly, the sixth connecting member rotates relative to the base frame assembly along a predetermined trajectory, causing the sixth rotating member to rotate. Under the constraint of the sixth link assembly, the sixth connecting member can slide away from the sixth rotating member, moving it away from the base frame assembly to create more clearance space.

[0076] For example, during the unfolding of the hinge mechanism, the fifth connecting member rotates along a predetermined trajectory relative to the base frame assembly, causing the fifth rotating member to rotate. Under the constraint of the fifth link assembly, the fifth connecting member can slide towards the fifth rotating member, bringing it closer to the base frame assembly to cooperate with it and form a support structure. Similarly, the sixth connecting member rotates along a predetermined trajectory relative to the base frame assembly, causing the sixth rotating member to rotate. Under the constraint of the sixth link assembly, the sixth connecting member can slide towards the sixth rotating member, bringing it closer to the base frame assembly to cooperate with it and form a support structure.

[0077] During the rotation of the fifth rotating component, it can also drive the fourth linkage component to move within a preset area, thereby pulling the sixth linkage assembly through the eighth connecting part. This, in turn, drives the sixth connecting component and the sixth rotating component on the second side to move, achieving synchronous movement of the fifth and sixth connecting components and synchronous rotation of the fifth and sixth rotating components. Similarly, during the rotation of the sixth linkage assembly driven by the sixth connecting component, it can also drive the fourth linkage component to move within a preset area, thereby pulling the fifth moving component through the seventh connecting part. This, in turn, drives the fifth connecting component and the fifth linkage assembly on the first side to move, achieving synchronous movement of the fifth and sixth connecting components and synchronous rotation of the fifth and sixth rotating components. Thus, by using the fourth linkage component to achieve synchronous movement of the fifth and sixth connecting components on both sides of the base frame assembly, compared to a gear synchronization structure, it occupies less space, improves the compactness of the hinge mechanism, and is beneficial for achieving a thinner and lighter foldable electronic device.

[0078] The technical solution of this disclosure will be further explained below:

[0079] In one embodiment, the fifth rotating member is rotatably connected to the first side and has a seventh rotation axis; the fifth rotating member is rotatably connected to the seventh connecting part and has an eighth rotation axis; the seventh rotation axis and the eighth rotation axis are not coaxial. The sixth link assembly is rotatably connected to the second side and has a ninth rotation axis; the sixth link assembly is rotatably connected to the eighth connecting part and has a tenth rotation axis; the ninth rotation axis and the tenth rotation axis are not coaxial.

[0080] And / or, the fifth link assembly is also drive-connected to the fifth rotating member, and the sixth link assembly is also drive-connected to the sixth rotating member.

[0081] And / or, when the hinge mechanism is in the deployed state, the load-bearing component and the base frame component cooperate to form a support structure. When the hinge mechanism is in the folded state, the load-bearing component and the base frame component intersect at an angle to create clearance space. The hinge mechanism can drive the fifth and sixth connecting components to move synchronously via the fourth linkage, thereby switching the hinge mechanism between the deployed and folded states.

[0082] According to a fourth aspect of the present disclosure, a hinge mechanism is provided, including a base frame assembly, a load-bearing assembly, a fifth link assembly, a sixth link assembly, a seventh rotating member, an eighth rotating member, and a fifth linkage member. The base frame assembly includes a first side portion and a second side portion disposed along its width direction. The load-bearing assembly includes a fifth connecting member disposed near the first side portion and a sixth connecting member disposed near the second side portion. The fifth link assembly is disposed between the first side portion and the fifth connecting member, and is rotatably connected to the base frame assembly and the fifth connecting member. The sixth link assembly is disposed between the second side portion and the sixth connecting member, and is rotatably connected to the base frame assembly and the sixth connecting member. The seventh rotating member is rotatably connected to the first side portion and slidably connected to the fifth connecting member. The eighth rotating member is disposed near the second side portion and slidably connected to the sixth connecting member. The fifth linkage member includes a ninth connecting portion, a tenth connecting portion, and a fifth limiting structure disposed between the ninth and tenth connecting portions. The ninth connecting portion is rotatably connected to the eighth rotating member, and the tenth connecting portion is rotatably connected to the fifth link assembly. The fifth limiting structure cooperates with the base frame assembly to limit the movement of the fifth linkage component relative to the base frame assembly within a preset area.

[0083] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0084] During the assembly of this hinge mechanism, the seventh rotating member is rotatably connected to the first side, and the fifth and sixth link assemblies are respectively assembled onto the base frame assembly. The fifth linkage member is assembled onto the base frame assembly via the fifth limiting structure and is rotatably connected to the eighth rotating member via the ninth connecting part, and rotatably connected to the fifth link assembly via the tenth connecting part, allowing the fifth link assembly to drive the eighth rotating member to rotate via the fifth linkage member. Then, the fifth connecting member is also assembled onto the first side of the base frame assembly via a sliding connection with the seventh rotating member and a rotatable connection with the fifth link assembly. Similarly, the sixth connecting member is also assembled onto the second side of the base frame assembly via a sliding connection with the eighth rotating member and a rotatable connection with the sixth link assembly, allowing the fifth and sixth connecting members to rotate relative to the base frame assembly.

[0085] Specifically, the fifth connecting member rotates relative to the base frame assembly via the fifth link assembly, thus restricting its rotational trajectory. When the seventh rotating member rotates, the fifth connecting member follows its rotation, and due to the restriction of the fifth link assembly, it also slides relative to the seventh rotating member. In other words, the fifth connecting member is assembled onto the base frame assembly via the seventh rotating member and the fifth link assembly, enabling it to move relative to the base frame assembly along a predetermined trajectory. Similarly, the sixth connecting member is assembled onto the base frame assembly via the eighth rotating member and the sixth link assembly, enabling it to move relative to the base frame assembly along a predetermined trajectory.

[0086] For example, during the folding process of the hinge mechanism, the fifth connecting member rotates along a predetermined trajectory relative to the base frame assembly, causing the seventh rotating member to rotate. Under the constraint of the fifth link assembly, the fifth connecting member slides away from the seventh rotating member, moving it away from the base frame assembly to create more clearance space. Similarly, the sixth connecting member rotates along a predetermined trajectory relative to the base frame assembly, causing the eighth rotating member to rotate. Under the constraint of the sixth link assembly, the sixth connecting member can slide away from the eighth rotating member, moving it away from the base frame assembly to create more clearance space.

[0087] For example, during the unfolding of the hinge mechanism, the fifth connecting member rotates along a predetermined trajectory relative to the base frame assembly, causing the seventh rotating member to rotate. Under the constraint of the fifth link assembly, the fifth connecting member can slide towards the seventh rotating member, bringing it closer to the base frame assembly to cooperate with it and form a support structure. Similarly, the sixth connecting member rotates along a predetermined trajectory relative to the base frame assembly, causing the eighth rotating member to rotate. Under the constraint of the sixth link assembly, the sixth connecting member can slide towards the eighth rotating member, bringing it closer to the base frame assembly to cooperate with it and form a support structure.

[0088] As the fifth connector drives the fifth linkage assembly to rotate, it also moves the fifth linkage component within a preset area. This, in turn, pulls the eighth moving component through the ninth connector, which in turn moves the sixth connector and the sixth linkage assembly on the second side, achieving synchronous movement between the fifth and sixth connectors, and synchronous rotation between the fifth and sixth rotating components. Thus, by using the fifth linkage component to achieve synchronous movement of the fifth and sixth connectors on both sides of the base frame assembly, compared to a gear synchronization structure, it occupies less space, improves the compactness of the hinge mechanism, and facilitates the thinning and lightening of foldable electronic devices.

[0089] The technical solution of this disclosure will be further explained below:

[0090] In one embodiment, the fifth link assembly is rotatably connected to the first side and has an eleventh rotation axis, the fifth link assembly is rotatably connected to the tenth connecting part and has a twelfth rotation axis, and the eleventh rotation axis and the twelfth rotation axis are not coaxial.

[0091] And / or, the fifth link assembly is also drive-connected to the seventh rotating member, and the sixth link assembly is also drive-connected to the eighth rotating member.

[0092] And / or, when the hinge mechanism is in the deployed state, the load-bearing component and the base frame component cooperate to form a support structure. When the hinge mechanism is in the folded state, the load-bearing component and the base frame component intersect at an angle to create clearance space. The hinge mechanism can drive the fifth and sixth connecting components to move synchronously via the fifth linkage, thereby switching the hinge mechanism between the deployed and folded states.

[0093] According to a fifth aspect of this disclosure, a foldable electronic device is also provided, including a housing assembly, a flexible display screen, and a hinge mechanism as described in any of the foregoing embodiments. The housing assembly includes a housing body connected to a support assembly. At least a portion of the flexible display screen covers the housing assembly and the hinge mechanism.

[0094] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0095] This foldable electronic device utilizes the hinge mechanism described in any of the above embodiments and is connected to the shell body via a support component. This allows the support component to unfold or fold the shell body and the flexible display screen covering it. During this process, the hinge mechanism occupies minimal space. Consequently, the foldable electronic device boasts a highly compact structure, facilitating the miniaturization and thinning of foldable electronic devices.

[0096] The technical solution of this disclosure will be further explained below:

[0097] In one embodiment, when the hinge mechanism is in the unfolded state, the support component and the base frame component cooperate to form a support structure to support the flexible display screen. When the hinge mechanism is in the folded state, the support component and the base frame component intersect at an angle to form a clearance space, within which a portion of the flexible display screen bends.

[0121] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0122] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0123] Mobile phones, tablets, and other electronic devices have become indispensable technological products in people's lives, studies, and entertainment, bringing them numerous conveniences and enjoyment. With the diversification of electronic device functions, there are now many types and brands available, offering consumers a wide range of choices. Simply improving the functional features of electronic devices is no longer sufficient to meet people's demands.

[0124] As flexible displays become increasingly sophisticated, their application in electronic devices is becoming more widespread. Foldable electronic devices using flexible displays offer the advantage of folding for portability. Furthermore, the unfolded flexible display provides a larger display area, making them increasingly popular with consumers. Among foldable electronic devices with similar display size and performance, the lighter and more comfortable the device is to hold, the more attractive it is to consumers.

[0125] In related technologies, foldable electronic devices typically utilize hinge mechanisms to enable flexible displays to unfold or fold. Traditional hinge mechanisms usually employ gear structures for transmission, but gear transmission schemes occupy a significant amount of space, hindering the compactness of the hinge mechanism and the achievement of a thinner and lighter design for foldable electronic devices. For example, in terms of the thickness of the hinge mechanism, gear transmission requires a certain amount of clearance for rotation, resulting in a larger thickness and making it difficult to make the hinge mechanism thinner. Furthermore, gear meshing transmission requires the design of a transmission structure and lubrication space, which also occupies space.

[0126] Based on this, the present disclosure provides a hinge mechanism that can switch between an unfolded state and a folded state, and occupies little space, which is beneficial to improving the compactness of the hinge mechanism and realizing the thinning and lightening of foldable electronic devices.

[0127] To better understand the hinge mechanism of this disclosure, it is illustrated by a foldable electronic device in which the hinge mechanism is applied.

[0128] like Figures 1 to 3 As shown, where, Figure 1 This is a partial structural schematic diagram of a foldable electronic device shown in one embodiment. Figure 2 This is a schematic diagram of a hinge mechanism shown in one embodiment. Figure 3 This is a schematic diagram of the hinge mechanism shown in one embodiment (wherein the hinge mechanism is in the unfolded state).

[0129] In embodiments of this disclosure, a foldable electronic device 10 is provided, including a housing assembly 10c, a flexible display screen 10a, and a hinge mechanism 10b as described in any of the above embodiments. The housing assembly 10c includes a housing body 103. The hinge mechanism 10b includes a base frame assembly 100, a support assembly 200, and a connecting rod. At least a portion of the flexible display screen 10a covers the housing assembly 10c and the hinge mechanism 10b. The housing body 103 is connected to the support assembly 200 and rotates relative to the base frame assembly 100 via the connecting rod. This allows the support assembly 200 to unfold or fold the housing body 103 and the flexible display screen 10a covering the housing body 103.

[0130] Among them, such as Figure 2 as well as Figure 4As shown, in some embodiments, the base frame assembly 100 includes a first side portion 110 and a second side portion 120 spaced apart from the first side portion 110 along the width direction of the base frame assembly 100. The load-bearing assembly 200 includes a first connector 210 disposed near the first side portion 110 and a second connector 220 disposed near the second side portion 120. The linkage component includes a first rotating member 310, a second rotating member 320, a first linkage assembly 330, a second linkage assembly 340, a first linkage member 400, and a second linkage member 500. The first linkage assembly 330 is disposed between the first side portion 110 and the first connector 210, and is rotatably connected to the first connector 210. The second linkage assembly 340 is disposed between the second side portion 120 and the second connector 220, and is rotatably connected to the second connector 220. The first rotating member 310 is rotatably connected to the first side portion 110 and slidably connected to the first connector 210. The second rotating member 320 is rotatably connected to the second side portion 120 and slidably connected to the second connecting member 220. The first linkage member 400 includes a first connecting portion 410, a second connecting portion 420, and a first limiting structure 430 disposed between the first connecting portion 410 and the second connecting portion 420. The first connecting portion 410 is rotatably connected to the first rotating member 310, and the second connecting portion 420 is rotatably connected to the second link assembly 340. The first limiting structure 430 is limited in cooperation with the base frame assembly 100 to restrict the movement of the first linkage member 400 relative to the base frame assembly 100 within a preset area. The second linkage member 500 includes a third connecting portion 510, a fourth connecting portion 520, and a second limiting structure 530 disposed between the third connecting portion 510 and the fourth connecting portion 520. The third connecting portion 510 is rotatably connected to the second rotating member 320, and the fourth connecting portion 520 is rotatably connected to the first link assembly 330. The second limiting structure 530 cooperates with the base frame assembly 100 to limit the movement of the second linkage 500 relative to the base frame assembly 100 within a preset area.

[0131] During the assembly of the hinge mechanism 10b, the first rotating member 310 is rotatably connected to the first side part 110, the first linkage member 400 is assembled onto the base frame assembly 100 through the first limiting structure 430, and is rotatably connected to the first rotating member 310 through the first connecting part 410, and the second connecting part 420 is rotatably connected to the second link assembly 340. Then, the first rotating member 310 and the second link assembly 340 are assembled onto the base frame assembly 100 through the first linkage member 400, so that the first rotating member 310 can drive the second link assembly 340 to move through the first linkage member 400. The second linkage 500 is assembled onto the base frame assembly 100 via the second limiting structure 530, and is rotatably connected to the first link assembly 330 via the third connecting part 510. The fourth connecting part 520 is connected to the first link assembly 330, thereby assembling the second rotating member 320 and the first link assembly 330 onto the base frame assembly 100, allowing the second rotating member 320 to drive the first link assembly 330 to move via the second linkage 500. Then, the first connecting member 210 is also assembled onto the first side 110 of the base frame assembly 100 via a slidable connection to the first rotating member 310 and a rotatable connection to the first link assembly 330. Similarly, the second connecting member 220 is also assembled onto the second side 120 of the base frame assembly 100 via a slidable connection to the second rotating member 320 and a rotatable connection to the second link assembly 340, allowing the first connecting member 210 and the second connecting member 220 to rotate relative to the base frame assembly 100.

[0132] Specifically, the first connecting member 210 rotates relative to the base frame assembly 100 via the first link assembly 330, thus restricting the rotation trajectory of the first connecting member 210. When the first rotating member 310 rotates, the first connecting member 210 rotates with it, and due to the restriction of the first link assembly 330, the first connecting member 210 also slides relative to the first rotating member 310. That is, the first connecting member 210 is assembled onto the base frame assembly 100 via the first rotating member 310 and the first link assembly 330, allowing the first connecting member 210 to move relative to the base frame assembly 100 along a predetermined trajectory. Similarly, the second connecting member 220 is assembled onto the base frame assembly 100 via the second rotating member 320 and the second link assembly 340, allowing the second connecting member 220 to move relative to the base frame assembly 100 along a predetermined trajectory.

[0133] For example, refer to Figure 6 as well as Figure 12As shown, during the folding process of the hinge mechanism 10b, the first connecting member 210 rotates relative to the base frame assembly 100 along a set trajectory, causing the first rotating member 310 to rotate. Under the constraint of the first link assembly 330, the first connecting member 210 slides away from the first rotating member 310, thus moving the first connecting member 210 away from the base frame assembly 100 to create more clearance space 101. Similarly, the second connecting member 220 rotates relative to the base frame assembly 100 along a set trajectory, causing the second rotating member 320 to rotate. Under the constraint of the second link assembly 340, the second connecting member 220 slides away from the second rotating member 320, thus moving the second connecting member 220 away from the base frame assembly 100 to create more clearance space 101.

[0134] For example, refer to Figure 6 as well as Figure 13 As shown, during the unfolding process of the hinge mechanism 10b, the first connecting member 210 rotates relative to the base frame assembly 100 along a predetermined trajectory, causing the first rotating member 310 to rotate. Under the constraint of the first link assembly 330, the first connecting member 210 can slide towards the first rotating member 310, thus positioning the first connecting member 210 close to the base frame assembly 100 to cooperate with the base frame assembly 100 and form a support structure 102. Similarly, the second connecting member 220 rotates relative to the base frame assembly 100 along a predetermined trajectory, causing the second rotating member 320 to rotate. Under the constraint of the second link assembly 340, the second connecting member 220 can slide towards the second rotating member 320, thus positioning the second connecting member 220 close to the base frame assembly 100 to cooperate with the base frame assembly 100 and form a support structure 102.

[0135] During the rotation of the first rotating member 310, it can also drive the first linkage member 400 to move within a preset area, thereby pulling the second connecting rod assembly 340 through the second connecting part 420, which in turn drives the second connecting member 220 and the second rotating member 320 of the second side 120 to move, achieving synchronous movement of the first connecting member 210 and the second connecting member 220, and synchronous rotation of the first rotating member 310 and the second rotating member 320. During the rotation of the second rotating member 320, it can also drive the second linkage member 500 to move within a preset area, thereby pulling the first connecting rod assembly 330 through the fourth connecting part 520, which in turn drives the first connecting member 210 and the first rotating member 310 of the first side 110 to move, achieving synchronous movement of the first connecting member 210 and the second connecting member 220, and synchronous rotation of the first rotating member 310 and the second rotating member 320. Thus, the first connecting member 210 and the second connecting member 220 on both sides of the base frame assembly 100 can move synchronously through two linkage components. Compared with the gear synchronization structure, it occupies less space, which can improve the compactness of the hinge mechanism 10b and help to achieve the thinner and lighter foldable electronic device 10.

[0136] It should be noted that the sliding connection between rotating parts and connecting parts includes the fit between slide grooves and slide rails, etc. For example... Figure 12 as well as Figure 13 As shown, the first rotating member 310 is provided with a slide rail, and the first connecting member 210 is provided with a slide groove that slides with the slide rail. The second rotating member 320 is provided with a slide rail, and the second connecting member 220 is provided with a slide groove that slides with the slide rail.

[0137] It should be noted that the first rotating member 310 can drive the first linkage member 400 to move through various structures, thereby driving the second linkage assembly 340 to move through the first linkage member 400. For example, eccentric drive, etc.

[0138] Similarly, the second rotating member 320 can drive the second linkage member 500 to move through various structures, thereby driving the first linkage assembly 330 to move through the second linkage member 500. For example, eccentric drive, etc.

[0139] Reference Figure 2 In some embodiments, the first rotating member 310 is rotatably connected to the first side portion 110 and has a first rotation axis. The first rotating member 310 is also rotatably connected to the first connecting portion 410 and has a second rotation axis. The first rotation axis and the second rotation axis are not coaxial. Thus, during the rotation of the first rotating member 310, an eccentric driving force can be generated to drive the first linkage member 400 to move, which in turn drives the second linkage assembly 340 to move.

[0140] In one example, the first rotating member 310 is rotatably connected to the base frame assembly as shown in the diagram. Figure 2The large circle shown is the first axis of rotation, with its center line serving as the first rotation axis. The schematic diagram illustrating the rotatable connection between the first rotating member 310 and the first connecting portion 410 is as follows: Figure 2 The small circle shown is the second axis of rotation, and its center line is eccentric to the large circle. The first rotating component 310 rotates around the center line of the large circle (i.e., the first axis of rotation), causing the small circle to move eccentrically.

[0141] Reference Figure 2 It is understood that the second rotating member 320 is rotatably connected to the second side portion 120 and has a third rotation axis. The first rotating member 310 is rotatably connected to the first connecting portion 410 and has a fourth rotation axis. The third rotation axis and the fourth rotation axis are not coaxial. Similarly, during the rotation of the second rotating member 320, an eccentric driving force can be generated to drive the second linkage member 500 to move, and then drive the first linkage assembly 330 to move through the second linkage member 500.

[0142] In one example, the second rotating member 320 is rotatably connected to the base frame assembly as shown in the diagram. Figure 2 The large circle shown is the third axis of rotation, with its center line being the third rotation axis. The schematic diagram of the rotatable connection between the second rotating member 320 and the second connecting part 510 is as follows: Figure 2 The small circle shown is the fourth axis of rotation, and it has an eccentricity with the large circle. The second rotating component 320 rotates around the center line of the large circle (that is, the third axis of rotation), causing the small circle to move eccentrically.

[0143] In some embodiments, the first linkage assembly 330 is also driveably connected to the first rotating member 310. Thus, during the rotation of the first rotating member 310, in addition to driving the first linkage assembly 330 through the first connecting member 210, the first linkage assembly 330 can also be directly driven to rotate, making the movement of the first connecting member 210 smoother. The second linkage assembly 340 is also driveably connected to the second rotating member 320. Similarly, during the rotation of the second rotating member 320, in addition to driving the second linkage assembly 340 through the second connecting member 220, the second linkage assembly 340 can also be directly driven to rotate, making the movement of the second connecting member 220 smoother.

[0144] In some embodiments, when the hinge mechanism 10b is in the unfolded state, the support component 200 and the base frame component 100 cooperate to form a support structure 102 to support the flexible display screen 10a. This facilitates the use of the support structure 102 formed by the hinge mechanism 10b in conjunction with the shell body 103 to support the flexible display screen 10a, making it convenient for users to unfold and use the flexible display screen 10a, thus improving the display quality and user experience of the foldable electronic device 10. When the hinge mechanism 10b is in the folded state, the support component 200 and the base frame component 100 intersect at an angle to form a clearance space 101. Parts of the flexible display screen 10a can be bent within the clearance space 101, reducing the risk of damage. Simultaneously, the hinge mechanism 10b can also be used to protect the bent portion of the flexible display screen 10a, improving the durability of the foldable electronic device 10. The hinge mechanism 10b can drive the first connecting member 210 and the second connecting member 220 to move synchronously through the first linkage member 400 and the second linkage member 500, so that the hinge mechanism 10b can switch between the unfolded state and the folded state. The structure is more compact, which is conducive to the lightweight design of the hinge mechanism 10b.

[0145] It should be noted that "folded state" usually refers to the state in which the two shell bodies 103 overlap, including the inward folded state or the outward folded state.

[0146] The "unfolded state" is the non-folded state relative to the aforementioned "folded state," including the flattened state used when the flexible display screen 10a is unfolded.

[0147] like Figure 3 as well as Figure 4 As shown, the width direction of the base frame assembly 100 is the X-axis direction. The first connector 210 and the second connector 220 are spaced apart along the X-axis direction. The length direction of the base frame assembly 100 is the Y-axis direction. The width direction of the base frame assembly 100 is the Z-axis direction.

[0148] Optionally, such as Figure 4 as well as Figure 5 As shown, in some embodiments, the first linkage 400 and / or the second linkage 500 are plate-shaped. This further reduces the space occupied in the thickness direction of the base frame assembly 100, allowing the foldable electronic device 10 to be made thinner and lighter.

[0149] In some embodiments, when the first rotating member on the first side rotates clockwise, it can drive the second connecting rod assembly on the second side to rotate counterclockwise via the first linkage member, causing the first connecting member and the second connecting member to move towards each other. This, in turn, causes the first connecting member and the second connecting member to intersect with the base frame assembly at an angle, forming a clearance space and realizing the folding of the hinge mechanism. Conversely, when the first rotating member on the first side rotates counterclockwise, it can drive the second connecting rod assembly and the second rotating member on the second side to rotate clockwise via the first linkage member, causing the first connecting member and the second connecting member to move towards each other and realizing the unfolding of the hinge mechanism.

[0150] In some embodiments, when the second rotating member on the second side rotates counterclockwise, it can drive the first connecting rod assembly on the first side to rotate clockwise via the second linkage, causing the first connecting member and the second connecting member to move towards each other. This, in turn, causes the first connecting member and the second connecting member to intersect with the base frame assembly at an angle, forming a clearance space and realizing the folding of the hinge mechanism. Conversely, when the second rotating member on the second side rotates clockwise, it can drive the first connecting rod assembly and the first rotating member on the first side to rotate counterclockwise via the second linkage, causing the first connecting member and the second connecting member to move towards each other and realizing the unfolding of the hinge mechanism.

[0151] It should be noted that the specific implementation method of the connection between the first limiting structure and / or the second limiting structure and the base frame assembly can be flexibly set according to the preset movement trajectory required by the linkage, including but not limited to rotational connection, sliding connection or a combination of rotation and sliding connection.

[0152] like Figures 4 to 6 As shown, in some embodiments, the first limiting structure 430 and the base frame assembly 100 are provided with a first guide protrusion 431 on one side and a first sliding groove 141 that guides and engages with the first guide protrusion 431 on the other side. Thus, through the guiding engagement of the first guide protrusion 431 and the first sliding groove 141, the first guide protrusion 431 can move along the trajectory of the first sliding groove 141, and the first guide protrusion 431 can rotate within the first sliding groove 141, so as to facilitate the synchronous reverse rotation of the first connecting member 210 and the second connecting member 220 using the first linkage member 400.

[0153] Similarly, such as Figures 8 to 10As shown, in some embodiments, the second limiting structure 530 and the base frame assembly 100 are provided with a second guide protrusion 531 on one side and a second sliding groove 171 that guides and engages with the second guide protrusion 531 on the other side. Thus, through the guiding engagement of the second guide protrusion 531 and the second sliding groove 171, the second guide protrusion 531 can move along the trajectory of the second sliding groove 171, and the second guide protrusion 531 can rotate within the second sliding groove 171, so as to facilitate the synchronous reverse rotation of the first connecting member 210 and the second connecting member 220 using the second linkage member 500.

[0154] like Figures 4 to 6 As shown, in some embodiments, the base frame assembly 100 includes a first support surface 130 for forming a support structure 102, a first connecting protrusion 140 disposed opposite to the first support surface 130 along the thickness direction of the base frame assembly 100, and a second connecting protrusion 170 disposed opposite to the first support surface 130 along the thickness direction of the base frame assembly 100. The first connecting protrusion 140 is provided with a first sliding groove 141, and the second connecting protrusion 170 is provided with a second sliding groove 171. Thus, by disposing the first connecting protrusion 140 on the back side of the first support surface 130 and forming the first sliding groove 141 on the first connecting protrusion 140, the connection between the first linkage 400 and the base frame assembly 100 will not interfere with the supporting function of the base frame assembly 100. Similarly, the second connecting protrusion 170 is disposed on the back side of the first support surface 130, and the second sliding groove 171 is formed on the second connecting protrusion 170, so that the connection between the second linkage 500 and the base frame assembly 100 will not interfere with the supporting function of the base frame assembly 100.

[0155] like Figures 3 to 6 As shown, the width direction of the base frame assembly 100 is the X-axis direction. Two support components 200 are spaced apart along the X-axis direction. The thickness direction of the base frame assembly 100 is the Z-axis direction.

[0156] Optional, see you later Figure 5 As shown, in some embodiments, the first guide protrusion 431 is disposed on the first linkage member 400 and between the first connecting portion 410 and the second connecting portion 420. Thus, the first guide protrusion 431 is easily disposed on the first linkage member 400, and the first sliding groove 141 is easily disposed on the base frame assembly 100, ensuring the strength of the first linkage member 400. This ensures reliable connection between the first linkage member 400 and the base frame assembly 100, the first rotating member 310, and the second connecting rod assembly 340.

[0157] like Figures 3 to 7As shown, in some embodiments, the first slide groove 141 is inclined along the width direction of the base frame assembly 100. The first slide groove 141 includes a first end 1411 near the first rotating member 310 and a second end 1412 near the connecting rod assembly. Along the thickness direction of the base frame assembly 100, the first end 1411 is higher than the second end 1412. Thus, during the process of the hinge mechanism 10b switching from the unfolded state to the folded state, the first rotating member 310 needs to drive the first connecting member 210 to be set at an angle with the base frame assembly 100. At this time, as the first connecting portion 410 of the first linkage member 400 moves with the first rotating member 310, the first guide protrusion 431 moves from the second end 1412 toward the first end 1411, so that the first connecting portion 410 can protrude out of the base frame assembly 100, and the part that does not interfere with the first rotating member 310 is disposed above the base frame assembly 100. During the transition of the hinge mechanism 10b from the folded state to the unfolded state, a portion of the first rotating member 310 needs to retract below the base frame assembly 100, without interfering with the cooperation between the load-bearing assembly 200 and the base frame assembly 100 to form the support structure 102. At this time, the first guide protrusion 431 moves from the first end 1411 towards the second end 1412, causing the first connecting portion 410 to also retract, without interfering with the cooperation between the load-bearing assembly 200 and the base frame assembly 100 to form the support structure 102.

[0158] like Figure 4 As shown, in some embodiments, the first rotating member 310 includes a first connecting body 311 rotatably connected to the first side portion 110, a first sliding body 312 slidably connected to the first connecting member 210, and a second connecting body 313 disposed between the first connecting body 311 and the first sliding body 312. The second connecting body 313 is rotatably connected to the first connecting portion 410. Since the rotation axis of the first connecting body 311 and the rotation axis of the second connecting body 313 are not on the same straight line, the first connecting body 311 rotates with the base frame assembly 100, driving the second connecting body 313 to rotate, forming an eccentric driving force. Furthermore, the first rotating member 310 can drive the second connecting rod assembly 340 on the other side to rotate through the first linkage member 400, realizing the synchronous reverse movement of the first connecting rod 331 component and the second connecting rod 341 component.

[0159] It should be noted that there are various ways to achieve the sliding connection between the first sliding body 312 and the first connecting member 210, including but not limited to slide rail structure, slide groove and slider, etc.

[0160] It should be noted that there are various ways to achieve the rotatable connection between the second connecting body 313 and the first connecting part 410, including hinge, shaft connection, and the cooperation of arc-shaped guide rail and arc-shaped guide groove, etc.

[0161] Optionally, such as Figures 4 to 7As shown, in some embodiments, the second connecting body 313 and the first connecting part 410 are provided with a first shaft 301 on one side and a first mating hole 411 that rotatably engages with the first shaft 301 on the other side. In this way, the second connecting body 313 and the first connecting part 410 can be rotatably connected simply by inserting the first shaft 301 into the first mating hole 411, which is easy to implement and convenient to assemble.

[0162] Furthermore, see you again Figure 4 As shown, in some embodiments, the base frame assembly 100 is provided with a first rotating part 150 rotatably connected to the first connecting body 311 and a first clearance groove 160 adjacent to the first rotating part 150, and the first linkage member 400 passes through the first clearance groove 160. In this way, by providing the first clearance groove 160, the first linkage member 400 and the first rotating part 310 are more tightly fitted, and the arrangement of the first linkage member 400 and the first connecting rod 331 in the base frame assembly 100 is more compact, which is conducive to the miniaturization of the hinge mechanism 10b and reduces the occupation of the internal space of the foldable electronic device 10.

[0163] Furthermore, by incorporating the mating scheme between the first shaft 301 and the first mating hole 411, a first clearance groove 160 is provided. This facilitates the rotational engagement of the first shaft 301 and the first mating hole 411, followed by the rotational engagement of the first connecting body 311 and the first rotating part 150, making assembly more convenient.

[0164] Optionally, such as Figure 6 As shown, in some embodiments, the first rotating part 150 is convex and is disposed opposite to the first supporting surface 130 along the thickness direction of the base frame assembly 100. Thus, the convex shape of the first rotating part 150 facilitates rotational connection with the first connecting body 311. Furthermore, the arrangement of the first rotating part 150 does not interfere with the cooperation between the first supporting surface 130 and the bearing assembly 200 to form the supporting structure 102.

[0165] It should be noted that there are various ways to achieve the rotatable connection between the first connecting body 311 and the first rotating part 150, including hinge, shaft connection, and the cooperation of arc-shaped guide rail and arc-shaped guide groove, etc.

[0166] Optional, see you later Figure 4As shown, in some embodiments, the base frame assembly 100 is provided with a first connecting protrusion 140, and the first connecting protrusion 140 is provided with a first sliding groove 141 that slides with the first linkage member 400. Along the length direction of the base frame assembly 100, a first clearance groove 160 is provided between the first connecting protrusion 140 and the first rotating part 150. In this way, it is convenient to connect the first connecting protrusion 140 to the first linkage member 400, then to rotate the second connecting body 313 to the first linkage member 400, and finally to rotate the first connecting body 311 to the first rotating part 150. The assembly is convenient and can effectively improve the assembly efficiency of the first linkage member 400 and the first rotating part 310 to the base frame assembly 100.

[0167] In conjunction with any embodiment of the guide protrusion, such as Figure 4 as well as Figure 5 As shown, in some embodiments, the first linkage 400 includes a first body 440, a second body 450, and a first guide protrusion 431. One end of the first body 440 is provided with a first connecting portion 410, and the other end is bent and connected to one end of the second body 450. The other end of the second body 450 is provided with a second connecting portion 420. The first guide protrusion 431 is disposed between the first body 440 and the second body 450. Thus, by bending and connecting the first body 440 and the second body 450, the first connecting portion 410 and the second connecting portion 420 can swing relative to the first guide protrusion 431 and slide relative to the base frame assembly 100 with the first guide protrusion 431. Consequently, the first rotating member 310 can drive the second link assembly 340 on the other side to rotate through the first linkage 400. Alternatively, the second link assembly 340 can drive the first rotating member 310 to rotate through the first linkage 400.

[0168] like Figure 8 as well as Figure 9 As shown, in some embodiments, the second guide protrusion 531 is disposed on the second linkage member 500 and between the third connecting portion 510 and the fourth connecting portion 520. Thus, the second guide protrusion 531 is easily disposed on the second linkage member 500, and the second sliding groove 171 is easily disposed on the base frame assembly 100, ensuring the strength of the second linkage member 500. This ensures reliable connection between the second linkage member 500 and the base frame assembly 100, the second rotating member 320, and the first connecting rod assembly 330.

[0169] like Figures 8 to 10As shown, in some embodiments, the second slide groove 171 is inclined along the width direction of the base frame assembly 100. The second slide groove 171 includes a third end 1711 and a fourth end 1712. Along the width direction of the base frame assembly 100, the third end 1711 is closer to the second rotating member 320 than the fourth end 1712. And in the thickness direction of the base frame assembly 100, the third end 1711 is higher than the fourth end 1712. Thus, during the process of the hinge mechanism 10b switching from the unfolded state to the folded state, the second rotating member 320 needs to drive the second connecting member 220 to be set at an angle with the base frame assembly 100. At this time, as the third connecting portion 510 of the second linkage member 500 moves with the second rotating member 320, the second guide protrusion 531 moves from the fourth end 1712 toward the third end 1711, so that the third connecting portion 510 can protrude out of the base frame assembly 100, and the part that does not interfere with the second rotating member 320 is disposed above the base frame assembly 100. During the transition of the hinge mechanism 10b from the folded state to the unfolded state, a portion of the second rotating member 320 needs to retract below the base frame assembly 100, without interfering with the cooperation between the load-bearing assembly 200 and the base frame assembly 100 to form the support structure 102. At this time, the second guide protrusion 531 moves from the third end 1711 towards the fourth end 1712, causing the third connecting portion 510 to also retract, without interfering with the cooperation between the load-bearing assembly 200 and the base frame assembly 100 to form the support structure 102.

[0170] like Figures 8 to 10 As shown, in some embodiments, the second rotating member 320 includes a third connecting body 321 rotatably connected to the second side portion 120, a second sliding body 322 slidably connected to the second connecting member 220, and a fourth connecting body 323 disposed between the third connecting body 321 and the second sliding body 322. The fourth connecting body 323 is rotatably connected to the third connecting portion 510. Since the rotation axis of the third connecting body 321 and the rotation axis of the fourth connecting body 323 are not on the same straight line, the rotation of the third connecting body 321 and the base frame assembly 100 drives the fourth connecting body 323 to rotate, forming an eccentric driving force. Consequently, the second rotating member 320 can drive the first connecting rod assembly 330 on the other side to rotate through the second linkage member 500, realizing the synchronous reverse movement of the first connecting rod 331 and the second connecting rod 341.

[0171] It should be noted that there are various ways to achieve the sliding connection between the second sliding body and the second connecting member, including but not limited to slide rail structure, slide groove and slider, etc.

[0172] It should be noted that there are several ways to achieve the rotatable connection between the fourth connecting body and the third connecting part, including hinge, shaft connection, and the combination of arc-shaped guide rail and arc-shaped guide groove, etc.

[0173] Optionally, such as Figure 8 as well as Figure 9 As shown, in some embodiments, a second shaft 302 is provided on one side of the fourth connector 323 and the third connector 510, and a second mating hole 511 is provided on the other side to rotatably engage with the second shaft 302. In this way, the rotatable connection between the fourth connector 323 and the third connector 510 can be achieved simply by inserting the second shaft 302 into the second mating hole 511, which is easy to implement and convenient to assemble.

[0174] Furthermore, see you again Figure 8 As shown, in some embodiments, the base frame assembly 100 is provided with a second rotating part 180 rotatably connected to the third connecting body 321 and a second clearance groove 190 adjacent to the second rotating part 180, and the second linkage member 500 passes through the second clearance groove 190. In this way, by providing the second clearance groove 190, the second linkage member 500 and the second rotating member 320 are more tightly fitted, and the arrangement of the second linkage member 500 and the second connecting rod 341 in the base frame assembly 100 is more compact, which is conducive to the miniaturization of the hinge mechanism 10b and reduces the occupation of the internal space of the foldable electronic device 10.

[0175] Furthermore, by incorporating the fit between the second shaft 302 and the second mating hole 511, a second clearance groove 190 is provided. This facilitates the rotational fit between the second shaft 302 and the second mating hole 511, followed by the rotational fit between the third connecting body 321 and the second rotating part 180, making assembly more convenient.

[0176] Optionally, such as Figure 8 As shown, in some embodiments, the third rotating part is convex and is disposed opposite to the first support surface 130 along the thickness direction of the base frame assembly 100. Thus, the second rotating part 180 is convex, facilitating rotational connection with the third connector 321. Furthermore, the arrangement of the second rotating part 180 does not interfere with the cooperation between the first support surface 130 and the bearing assembly 200 to form the support structure 102.

[0177] It should be noted that there are various ways to realize the rotatable connection between the third connecting body 321 and the second rotating part 180, including hinge, shaft connection, and the cooperation of arc-shaped guide rail and arc-shaped guide groove, etc.

[0178] Optional, see you later Figure 8As shown, in some embodiments, the base frame assembly 100 is provided with a second connecting protrusion 170, and the second connecting protrusion 170 is provided with a second sliding groove 171 that slides with the second linkage member 500. Along the length direction of the base frame assembly 100, a second clearance groove 190 is provided between the second connecting protrusion 170 and the second rotating part 180. In this way, it is convenient to connect the second connecting protrusion 170 and the second linkage member 500, then to rotatably connect the fourth connecting body 323 and the second linkage member 500, and finally to rotatably connect the third connecting body 321 and the second rotating part 180. The assembly is convenient and can effectively improve the assembly efficiency of the second linkage member 500 and the second rotating part 320 to the base frame assembly 100.

[0179] In conjunction with any embodiment of the guide protrusion, such as Figure 8 As shown, in some embodiments, the second linkage 500 includes a third body 540, a fourth body 550, and a second guide protrusion 531. One end of the third body 540 is provided with a third connecting portion 510, and the other end is bent and connected to one end of the fourth body 550. The other end of the fourth body 550 is provided with a fourth connecting portion 520. The second guide protrusion 531 is disposed between the third body 540 and the fourth body 550. Thus, by bending and connecting the third body 540 and the fourth body 550, the third connecting portion 510 and the fourth connecting portion 520 can swing relative to the second guide protrusion 531 and slide relative to the base frame assembly 100 with the second guide protrusion 531. Consequently, the second rotating member 320 can drive the first connecting rod assembly 330 on the other side to rotate through the second linkage 500. Alternatively, the first connecting rod assembly 330 can drive the second rotating member 320 to rotate through the second linkage 500.

[0180] like Figure 3 , Figure 4 as well as Figure 8 As shown, in some embodiments, the first rotating member 310 and the second rotating member 320 are spaced apart along the length of the base frame assembly 100. Along the length of the base frame assembly 100, the first connecting rod assembly 330 and the second connecting rod assembly 340 are disposed between the first rotating member 310 and the second rotating member 320. Thus, the first rotating member 310 and the second rotating member 320 are staggered, facilitating the linkage between the first rotating member 310 and the second connecting rod assembly 340 using the first linkage member 400, and the linkage between the second rotating member 320 and the first connecting rod assembly 330 using the second linkage member 500. Furthermore, the first linkage member 400 and the second linkage member 500 fit tightly, making the structure of the hinge mechanism 10b more compact.

[0181] like Figure 3 , Figure 4 as well as Figure 8As shown, in some embodiments, the hinge mechanism 10b further includes a first stabilizing member 350, which is rotatably connected to the first side portion 110 and slidably connected to the first connecting member 210. The first stabilizing member 350 and the second rotating member 320 are spaced apart along the width direction of the base frame assembly 100. Thus, the first rotating member 310 and the first stabilizing member 350 rotate synchronously in opposite directions, ensuring that the first connecting member 210 and the second connecting member 220 experience uniform force during rotation, resulting in smoother movement.

[0182] like Figure 3 , Figure 4 as well as Figure 8 As shown, in some embodiments, the hinge mechanism 10b further includes a second stabilizing member 360, which is rotatably connected to the second side portion 120 and slidably connected to the second connecting member 220. The second stabilizing member 360 and the first rotating member 310 are spaced apart along the width direction of the base assembly 100. Thus, the second rotating member 320 and the second stabilizing member 360 rotate synchronously in opposite directions, ensuring that the second connecting member 220 experiences uniform force during rotation, resulting in smoother movement.

[0183] like Figure 3 , Figure 4 as well as Figure 8 As shown, or Figure 14 As shown, in some embodiments, the first linkage assembly 330 includes a first linkage 331. One end of the first linkage 331 is rotatably connected to the fourth connecting portion 520, and the other end of the first linkage 331 is directly or indirectly rotatably connected to the first connecting member 210. Thus, during rotation relative to the base frame assembly 100, the first rotating member 310 can drive the first connecting member 210 to slide along a predetermined direction, and the first linkage 331 can limit the swing direction of the first connecting member 210, thereby switching the first connecting member 210 between a supported state and a folded state.

[0184] like Figure 3 , Figure 4 as well as Figure 8 As shown, or Figure 14 As shown, in some embodiments, the second linkage assembly 340 includes a second linkage 341, one end of which is rotatably connected to the second connecting portion 420, and the other end of which is directly or indirectly rotatably connected to the second connecting member 220. Thus, during rotation relative to the base frame assembly 100, the second rotating member 320 can drive the second connecting member 220 to slide along a predetermined direction, and the second linkage 341 can limit the swing direction of the second connecting member 220, thereby switching the second connecting member 220 between a supported state and a folded state.

[0185] It should be noted that the other end of the first link 331 is rotatably connected to the connector, either directly or indirectly through other links. The other end of the second link 341 is rotatably connected to the connector, either directly or indirectly through other links.

[0186] Optionally, such as Figure 14 As shown, the other end of the first link 331 is directly rotatably connected to the first connector 210, and the other end of the second link 341 is directly rotatably connected to the second connector 220. Thus, by the first link assembly 330 and the first rotating member 310 cooperating at the first side 110 to form a secondary link mechanism, and by the second link assembly 340 and the second rotating member 320 cooperating at the second side 120 to form a secondary link mechanism, the hinge mechanism 10b can form a teardrop-shaped clearance space 101 in the folded state, which can meet the bending space required for the flexible display screen 10a to bend, thereby improving the service life of the flexible display screen 10a.

[0187] In the two-stage linkage design, during the rotation of the first rotating member 310, it can also drive the first linkage member 400 to move within a preset area, thereby pulling the second linkage 341 through the second connecting part 420. At this time, the second linkage 341 can directly drive the second connecting member 220 and the second rotating member 320 to move, thereby achieving synchronous movement of the first connecting member 210 and the second connecting member 220, and synchronous rotation of the first rotating member 310 and the second rotating member 320.

[0188] Similarly, during the rotation of the second rotating member 320, it can also drive the second linkage member 500 to move within a preset area, thereby pulling the first connecting rod 331 to move through the fourth connecting part 520. At this time, the first connecting rod 331 can directly drive the first connecting member 210 and the first rotating member 310 to move, thereby realizing the synchronous movement of the first connecting member 210 and the second connecting member 220, and the synchronous rotation of the first rotating member 310 and the second rotating member 320.

[0189] like Figure 3 , Figure 4 as well as Figure 8 As shown, or Figure 11 as well as Figure 12As shown, in some embodiments, the first link assembly 330 further includes a third link 332 and a fourth link 333. The other end of the first link 331 is rotatably connected to the first connector 210 via the third link 332. One end of the fourth link 333 is rotatably connected to one end of the first link 331 and one end of the third link 332, and the other end of the fourth link 333 is rotatably connected to the first rotating member 310. The second link assembly 340 further includes a fifth link 342 and a sixth link 343. The other end of the second link 341 is rotatably connected to the first connector 210 via the fifth link 342. One end of the sixth link 343 is rotatably connected to the other end of the second link 341 and one end of the fifth link 342, and the other end of the sixth link 343 is rotatably connected to the second rotating member 320. Thus, during its rotation relative to the base frame assembly 100, the first rotating member 310 can drive the first connecting member 210 to slide along a predetermined direction. It also engages with the first rotating member 310 via a fourth link 333 to restrict the rotational trajectories of the first link 331 and the third link 332. This, in turn, causes the first connecting member 210 to swing along a predetermined trajectory, allowing it to switch between a supported and folded state. Similarly, during its rotation relative to the base frame assembly 100, the second rotating member 320 can drive the second connecting member 220 to slide along a predetermined direction. It also engages with the second rotating member 320 via a sixth link 343 to restrict the rotational trajectories of the second link 341 and the fifth link 342. This, in turn, causes the second connecting member 220 to swing along a predetermined trajectory, allowing it to switch between a supported and folded state.

[0190] On the first side 110, a three-stage linkage mechanism is formed by the cooperation of the first link 331, the third link 332 and the fourth link 333. The cooperation of the fourth link 333 with the first rotating member 310 restricts the rotation of the first link 331 and the third link 332, so that the first connecting member 210 can move further away from the base frame assembly 100. This makes the teardrop-shaped clearance space 101 formed by the hinge mechanism 10b in the folded state more elongated, and can more accurately provide the bending space required for the flexible display screen 10a to bend, and better fit the flexible display screen 10a, thus protecting the flexible display screen 10a in the folded state. Similarly, the second side 120 forms a three-stage linkage mechanism through the cooperation of the second link 341, the fifth link 342 and the sixth link 343. The cooperation of the sixth link 343 with the second rotating member 320 restricts the rotation of the second link 341 and the fifth link 342, so that the second connecting member 220 can move further away from the base frame assembly 100. This makes the teardrop-shaped clearance space 101 formed by the hinge mechanism 10b in the folded state more elongated, and can more accurately provide the bending space required for the flexible display screen 10a to bend, and better fit the flexible display screen 10a, thus protecting the flexible display screen 10a in the folded state.

[0191] In the three-stage linkage scheme, during the rotation of the first rotating member 310, it can also drive the first linkage member 400 to move within a preset area, thereby pulling the second linkage 341 through the second connecting part 420. The second linkage 341 pulls the fourth linkage 333 and the fifth linkage 342, and then the fourth linkage 333 pulls the second rotating member 320 to rotate, which can also drive the second connecting member 220 of the second side 120 to move, so that the first connecting member 210 and the second connecting member 220 move synchronously, and the first rotating member 310 and the second rotating member 320 rotate synchronously.

[0192] Similarly, during the rotation of the second rotating member 320, it can also drive the second linkage member 500 to move within a preset area. This, in turn, pulls the first connecting rod 331 through the fourth connecting part 520. The first connecting rod 331 pulls the third connecting rod 332 and the fourth connecting rod 333, which in turn pulls the first rotating member 310 to rotate. This, in turn, drives the first connecting member 210 of the first side part 110 to move, achieving synchronous movement of the first connecting member 210 and the second connecting member 220, and synchronous rotation of the first rotating member 310 and the second rotating member 320. Thus, by using two linkage members, the first connecting member 210 and the second connecting member 220 on both sides of the base frame assembly 100 can move synchronously. Compared to a gear synchronization structure, this method occupies less space, improves the compactness of the hinge mechanism 10b, and facilitates the thinning and lightening of the foldable electronic device 10.

[0193] Optionally, the first link 331, the third link 332, and the first rotating member 310 are connected by a pivot, further improving the structural compactness of the hinge mechanism 10b.

[0194] Optionally, the second link 341, the fifth link 342, and the second rotating member 320 are connected by a pivot, further improving the structural compactness of the hinge mechanism 10b.

[0195] In other embodiments, the first linkage assembly 330 further includes at least one link disposed between the first link 331 and the third link 332 to form a four-stage linkage mechanism, a five-stage linkage mechanism, etc.

[0196] In other embodiments, the second linkage assembly 340 further includes at least one link disposed between the second link 341 and the fifth link 342 to form a four-stage linkage mechanism, a five-stage linkage mechanism, etc.

[0197] On the longitudinal projection plane of the base frame assembly 100, when the hinge mechanism 10b is in the folded state, the width of the clearance space 101 gradually increases from the base frame assembly 100 to the other end of the first link 331 on the first side 110, and gradually decreases from one end of the third link 332 to the other end of the third link 332. On the second side 120, the width gradually increases from the base frame assembly 100 to the other end of the second link 341, and gradually decreases from one end of the fifth link 342 to the other end of the fifth link 342. Thus, the clearance space 101 gradually increases to reduce stress concentration. The gradual decrease in the width of the clearance space 101 from one end of the third link 332 to the other end of the third link 332 causes the flexible display screen 10a to gradually conform away from the base frame assembly 100. This not only facilitates the thinning and lightening of the foldable electronic device 10, but also enables the flexible display screen 10a to bend smoothly, thereby improving the bending lifespan of the flexible display screen 10a.

[0198] like Figure 2 as well as Figures 11 to 12As shown, in some embodiments, the supporting component 200 includes a first support plate 230 corresponding to the first connector 210. The first support plate 230 is rotatably connected to the first connector 210, and the first connector 210 is provided with a first clearance slope 211. When the hinge mechanism 10b is in the unfolded state, the first support plate 230 is positioned away from the first clearance slope 211 and cooperates with the base frame assembly 100 to form a support structure 102. When the hinge mechanism 10b is in the folded state, the first support plate 230 abuts against the first clearance slope 211 and is positioned at an angle to the base frame assembly 100 to form a clearance space 101. Thus, the first clearance slope 211 allows the first support plate 230 to move relative to the first connector 210, thereby forming a larger clearance space 101 in the folded state. When the hinge mechanism 10b is in the unfolded state, the first side portion 110 can move away from the first clearance slope 211, allowing the first support plate 230 to be used to form the support structure 102. The first connector 210 is fixedly connected to the shell body 103.

[0199] Similarly, in some embodiments, the supporting component 200 includes a second support plate 240 corresponding to the second connector 220. The second support plate 240 is rotatably connected to the second connector 220, and the second connector 220 is provided with a second clearance slope 221. When the hinge mechanism 10b is in the unfolded state, the second support plate 240 is positioned away from the second clearance slope 221 and cooperates with the base frame assembly 100 to form a support structure 102. When the hinge mechanism 10b is in the folded state, the second support plate 240 abuts against the second clearance slope 221 and is positioned at an angle to the base frame assembly 100 to form a clearance space 101. Thus, the second clearance slope 221 allows the second support plate 240 to move relative to the second connector 220, thereby forming a larger clearance space 101 in the folded state. When the hinge mechanism 10b is in the unfolded state, the second side 120 can move away from the second clearance slope 221, allowing the second support plate 240 to be used to form the support structure 102. The second connector 220 is fixedly connected to another shell body 103.

[0200] Understandably, by utilizing the technical solution of this disclosure, even if the foldable electronic device 10 is subjected to impacts such as drops when in the folded state, the rotating component will not move relative to the support plate due to the damping component 900, etc. The rotating component restricts the movement of the support plate, thereby preventing deformation of the clearance space 101. Since the support plate cannot move, it in turn limits the movement of the connecting component, and thus the connecting component will not cause the shell body 103 to move relative to the base frame assembly 100. This reliably protects the flexible display screen 10a and improves the drop resistance and reliability of the foldable electronic device 10.

[0201] Reference Figure 12 as well as Figure 13As shown, in some embodiments, when the hinge mechanism 10b is in the unfolded state, the support component 200 and the base frame component 100 cooperate to form a support structure 102. This allows the support structure 102 formed by the hinge mechanism 10b to cooperate with the shell body 103 to support the flexible display screen 10a, facilitating user access to the flexible display screen 10a. When the hinge mechanism 10b is in the folded state, the support component 200 and the base frame component 100 intersect at an angle to form a clearance space 101. This allows the clearance space 101 formed by the hinge mechanism 10b to prevent the flexible display screen 10a from bending, and also allows the hinge mechanism 10b to protect the bent portion of the flexible display screen 10a, improving the durability of the foldable electronic device 10.

[0202] It should be noted that "folded state" usually refers to the state in which the two shell bodies 103 overlap, including the inward folded state or the outward folded state.

[0203] The "unfolded state" is the non-folded state relative to the aforementioned "folded state," including the flattened state used when the flexible display screen 10a is unfolded.

[0204] like Figure 15 As shown, in some embodiments of the hinge mechanism 10b, the base frame assembly 100 includes a first side portion 110 and a second side portion 120 spaced apart from the first side portion 110 along the width direction of the base frame assembly 100. The load-bearing assembly 200 includes a first connector 210 disposed near the first side portion 110 and a second connector 220 disposed near the second side portion 120. The linkage component includes a third rotating member 610, a fourth rotating member 620, a third linkage assembly 630, a fourth linkage assembly 640, and a third linkage member 700. The third linkage assembly 630 is disposed between the first side portion 110 and the third connector 250, and is rotatably connected to the base frame assembly 100 and to the third connector 250. The fourth linkage assembly 640 is disposed between the second side portion 120 and the fourth connector 260, and is rotatably connected to the fourth connector 260. The third rotating member 610 is rotatably connected to the first side portion 110 and slidably connected to the third connecting member 250. The fourth rotating member 620 is rotatably connected to the second side portion 120 and slidably connected to the fourth connecting member 260. The third linkage member 700 includes a fifth connecting portion 710, a sixth connecting portion 720, and a third limiting structure 730 disposed between the fifth connecting portion 710 and the sixth connecting portion 720. The fifth connecting portion 710 is rotatably connected to the third rotating member 610, and the sixth connecting portion 720 is rotatably connected to the fourth link assembly 640. The third limiting structure 730 is limited in cooperation with the base frame assembly 100 to restrict the movement of the third linkage member 700 relative to the base frame assembly 100 within a preset area.

[0205] During the assembly of the hinge mechanism 10b, the third rotating member 610 is rotatably connected to the first side portion 110. The third linkage member 700 is assembled onto the base frame assembly 100 via the third limiting structure 730 and is rotatably connected to the third rotating member 610 via the fifth connecting portion 710. The sixth connecting portion 720 is rotatably connected to the fourth link assembly 640. The third linkage member 700 then assembles the third rotating member 610 and the fourth link assembly 640 onto the base frame assembly 100, enabling the third rotating member 610 to drive the fourth link assembly 640 to move via the third linkage member 700. The fourth rotating member 620 and the third link assembly 630 are then assembled onto the base frame assembly 100. Finally, the third connecting member 250 is also assembled onto the first side portion 110 of the base frame assembly 100 via a sliding connection with the third rotating member 610 and a rotatable connection with the third link assembly 630. Similarly, the fourth connector 260 is also assembled onto the second side 120 of the base frame assembly 100 through a sliding connection with the fourth rotating member 620 and a rotatable connection with the fourth link assembly 640, so that the third connector 250 and the fourth connector 260 can rotate relative to the base frame assembly 100.

[0206] Specifically, the third connecting member 250 rotates relative to the base frame assembly 100 via the third link assembly 630, thus restricting the rotation trajectory of the third connecting member 250. When the third rotating member 610 rotates, the third connecting member 250 rotates with it, and due to the restriction of the third link assembly 630, the third connecting member 250 also slides relative to the third rotating member 610. That is, the third connecting member 250 is assembled onto the base frame assembly 100 via the third rotating member 610 and the third link assembly 630, allowing the third connecting member 250 to move relative to the base frame assembly 100 along a set trajectory. Similarly, the fourth connecting member 260 is assembled onto the base frame assembly 100 via the fourth rotating member 620 and the fourth link assembly 640, allowing the fourth connecting member 260 to move relative to the base frame assembly 100 along a set trajectory.

[0207] For example, during the folding process of the hinge mechanism 10b, the third connector 250 rotates relative to the base frame assembly 100 along a set trajectory, causing the third rotating member 610 to rotate. Under the constraint of the third link assembly 630, the third connector 250 slides away from the third rotating member 610, thus moving the third connector 250 away from the base frame assembly 100 to create more clearance space 101. Similarly, the fourth connector 260 rotates relative to the base frame assembly 100 along a set trajectory, causing the fourth rotating member 620 to rotate. Under the constraint of the fourth link assembly 640, the fourth connector 260 can slide away from the fourth rotating member 620, thus moving the fourth connector 260 away from the base frame assembly 100 to create more clearance space 101.

[0208] For example, during the unfolding of the hinge mechanism 10b, the third connecting member 250 rotates relative to the base frame assembly 100 along a predetermined trajectory, causing the third rotating member 610 to rotate. Under the constraint of the third link assembly 630, the third connecting member 250 can slide towards the third rotating member 610, thus positioning the third connecting member 250 close to the base frame assembly 100 to cooperate with the base frame assembly 100 and form a support structure 102. Similarly, the fourth connecting member 260 rotates relative to the base frame assembly 100 along a predetermined trajectory, causing the fourth rotating member 620 to rotate. Under the constraint of the fourth link assembly 640, the fourth connecting member 260 can slide towards the fourth rotating member 620, thus positioning the fourth connecting member 260 close to the base frame assembly 100 to cooperate with the base frame assembly 100 and form a support structure 102.

[0209] During the rotation of the third rotating member 610, it can also drive the third linkage member 700 to move within a preset area, thereby pulling the fourth linkage assembly 640 through the sixth connecting part 720. This, in turn, drives the fourth connecting member 260 and the fourth rotating member 620 of the second side part 120 to move, achieving synchronous movement of the third connecting member 250 and the fourth connecting member 260, and synchronous rotation of the third rotating member 610 and the fourth rotating member 620. In this way, the third linkage member 700 can achieve synchronous movement of the third connecting member 250 and the fourth connecting member 260. Compared with the gear synchronization structure, it occupies less space, which can improve the compactness of the hinge mechanism 10b and help to achieve the thinner and lighter design of the foldable electronic device 10.

[0210] It should be noted that the third rotating component 610 can drive the third linkage component 700 to move through various structures, thereby driving the third linkage assembly 630 to move through the third linkage component 700. For example, eccentric drive, etc.

[0211] Reference Figure 15 In some embodiments, the third rotating member 610 is rotatably connected to the first side portion 110 and has a fifth rotation axis. The third rotating member 610 is also rotatably connected to the fifth connecting portion 710 and has a sixth rotation axis. The fifth and sixth rotation axes are not coaxial. Thus, during the rotation of the third rotating member 610, an eccentric driving force is generated to drive the third linkage member 700, which in turn drives the fourth linkage assembly 640.

[0212] In one example, the third rotating member 610 is rotatably connected to the base frame assembly as shown in the diagram. Figure 15 The large circle shown is the fifth axis of rotation, with its center line being the fifth rotation axis. The schematic diagram illustrating the rotatable connection between the third rotating member 610 and the fifth connecting part 710 is as follows: Figure 15The small circle shown is centered on the sixth axis of rotation and is offset from the large circle. The third rotating component 610 rotates around the center line of the large circle (i.e., the fifth axis of rotation), causing the small circle to move eccentrically.

[0213] In some embodiments, the third linkage assembly is also connected to the third rotating member via a transmission connection. Thus, during the rotation of the third rotating member, in addition to driving the third linkage assembly through the third connecting member, it can also directly drive the third linkage assembly to rotate, making the movement of the third connecting member smoother.

[0214] Furthermore, the fourth linkage assembly is also connected to the fourth rotating member via a transmission connection. Similarly, during the rotation of the fourth rotating member, in addition to driving the fourth linkage assembly through the fourth connecting member, it can also directly drive the fourth linkage assembly to rotate, making the movement of the fourth connecting member more stable.

[0215] In some embodiments, when the hinge mechanism is in the unfolded state, the support component and the base frame component cooperate to form a support structure to support the flexible display screen. This facilitates the use of the support structure formed by the hinge mechanism in conjunction with the shell body to support the flexible display screen, making it convenient for users to unfold and use the flexible display screen, improving the display quality and user experience of the foldable electronic device. When the hinge mechanism is in the folded state, the support component and the base frame component intersect at an angle to create a clearance space. The flexible display screen can bend within this clearance space, reducing the risk of damage. Simultaneously, the hinge mechanism can also protect the bent portion of the flexible display screen, improving the durability of the foldable electronic device. Furthermore, the hinge mechanism can drive the third and fourth connecting components to move synchronously via a third linkage, allowing the hinge mechanism to switch between the unfolded and folded states. This results in a more compact structure, which is beneficial for the lightweight design of the hinge mechanism.

[0216] It should be noted that "folded state" usually refers to the state in which the two shell bodies overlap, including inward folding or outward folding.

[0217] The "unfolded state" is the non-folded state relative to the aforementioned "folded state," including the flattened state used when the flexible display screen is unfolded.

[0218] The width direction of the base frame assembly is the X-axis direction. Third connecting members are spaced apart along the X-axis direction. The length direction of the base frame assembly is the Y-axis direction. The width direction of the base frame assembly is the Z-axis direction.

[0219] Optionally, in some embodiments, the third linkage is plate-shaped. This further reduces the space it occupies in the thickness direction of the base assembly, allowing the foldable electronic device to be made thinner and lighter.

[0220] In some embodiments, when the third rotating member rotates clockwise, the third connecting member also rotates, and through the third linkage member, drives the fourth link assembly to rotate counterclockwise. This causes the third and fourth connecting members to move towards each other, thereby causing the third and fourth connecting members to intersect with the base frame assembly at an angle to create clearance space and achieve folding of the hinge mechanism. Conversely, when the third rotating member rotates counterclockwise, the third link assembly also rotates, and through the third linkage member, drives the fourth link assembly to rotate clockwise. This causes the third and fourth connecting members to move towards each other, thereby causing the third and fourth connecting members to form a support structure with the base frame assembly and achieve unfolding of the hinge mechanism.

[0221] It should be noted that the specific implementation method of the movable connection between the third limiting structure and the base frame component can be flexibly set according to the preset trajectory required for the movement of the third linkage component, including but not limited to rotational connection, sliding connection or a combination of rotation and sliding connection.

[0222] In some embodiments, one of the third limiting structure and the base frame assembly is provided with a third guide protrusion (not shown), and the other is provided with a third sliding groove (not shown) that guides and engages with the third guide protrusion. In this way, through the guiding engagement of the third guide protrusion and the third sliding groove, the third guide protrusion can move along the trajectory of the third sliding groove, and the third guide protrusion can rotate within the third sliding groove, so as to facilitate the synchronous reverse rotation of the third connecting member and the fourth connecting member using the third linkage.

[0223] In some embodiments, the base frame assembly includes a first support surface for forming a support structure and a third connecting protrusion (not shown) disposed opposite to the first support surface along the thickness direction of the base frame assembly. The third connecting protrusion is provided with a third sliding groove. Thus, by disposing the third connecting protrusion on the back side of the first support surface and forming the third sliding groove on the third connecting protrusion, the connection between the third linkage and the base frame assembly will not interfere with the supporting function of the base frame assembly.

[0224] In some embodiments, the third guide protrusion is disposed on the third linkage member and between the fifth connecting portion and the sixth connecting portion. This facilitates the placement of the third guide protrusion on the third linkage member and the placement of the third sliding groove on the base frame assembly, ensuring the strength of the third linkage member. This ensures reliable connection between the third linkage member and the base frame assembly, the third rotating member, and the fourth link assembly.

[0225] In some embodiments, the third slide is inclined along the width direction of the base frame assembly. The third slide includes a fifth end and a sixth end. Along the width direction of the base frame assembly, the fifth end is closer to the third rotating member than the sixth end. Furthermore, in the thickness direction of the base frame assembly, the fifth end is higher than the sixth end. Thus, during the hinge mechanism's transition from the unfolded state to the folded state, the third rotating member needs to drive the third connecting member to be angled with the base frame assembly. At this time, as the fifth connecting portion of the third linkage moves with the third rotating member, the third guide protrusion moves from the sixth end towards the fifth end, allowing the fifth connecting portion to protrude from the base frame assembly without interfering with the portion of the third rotating member positioned above the base frame assembly. During the hinge mechanism's transition from the folded state to the unfolded state, the portion of the third rotating member needs to retract below the base frame assembly without interfering with the cooperation between the load-bearing component and the base frame assembly to form a support structure. At this time, the third guide protrusion moves from the fifth end towards the sixth end, causing the fifth connecting portion to also retract, without interfering with the cooperation between the load-bearing component and the base frame assembly to form a support structure.

[0226] In some embodiments, the third rotating member includes a fifth connecting body (not shown) rotatably connected to the first side, a third sliding body (not shown) slidably connected to the third connecting member, and a sixth connecting body (not shown) disposed between the fifth connecting body and the third sliding body, the sixth connecting body being rotatably connected to the fifth connecting part. The rotation axis of the fifth connecting body and the rotation axis of the sixth connecting body are not on the same straight line. Thus, during the rotation of the fifth connecting body and the base frame assembly, the sixth connecting body is driven to rotate, forming an eccentric driving force. Furthermore, the third rotating member can drive the fourth linkage assembly on the other side to rotate through the third linkage member, realizing the synchronous reverse movement of the third linkage component and the fourth linkage component.

[0227] It should be noted that there are various ways to achieve the sliding connection between the third sliding body and the third connecting member, including but not limited to slide rail structure, slide groove and slider, etc.

[0228] It should be noted that there are several ways to achieve the rotatable connection between the sixth connecting body and the fifth connecting part, including hinge, shaft connection, and the combination of arc-shaped guide rail and arc-shaped guide groove, etc.

[0229] In some embodiments, a third shaft (not shown) is provided between the sixth connector and the fifth connector, and a third mating hole (not shown) is provided between the sixth connector and the fifth connector to rotatably engage with the first shaft. In this way, the rotatable connection between the second connector and the third connector can be achieved simply by inserting the third shaft into the third mating hole, which is easy to implement and convenient to assemble.

[0230] In some embodiments, the first side is provided with a third rotating part rotatably connected to the fifth connecting body and a third clearance groove (not shown) adjacent to the third rotating part, and the third linkage member passes through the third clearance groove. In this way, by providing the third clearance groove, the third linkage member and the third rotating member fit more tightly, and the arrangement of the third linkage member and the third linkage component in the base frame assembly is more compact, which is conducive to miniaturizing the hinge mechanism and reducing the internal space occupied by the foldable electronic device.

[0231] Furthermore, by incorporating the mating scheme between the third shaft and the third mating hole, a third clearance groove is provided. This facilitates the rotational engagement of the third shaft and the third mating hole, followed by the rotational engagement of the fifth connecting body and the third rotating part, making assembly more convenient.

[0232] In some embodiments, the base frame assembly includes a first support surface for forming a support structure, and a third rotating portion is convex and disposed opposite to the first support surface along the thickness direction of the base frame assembly. Thus, the convex shape of the third rotating portion facilitates rotational connection with the fifth connecting body. Furthermore, the arrangement of the third rotating portion does not interfere with the cooperation between the first support surface and the load-bearing assembly to form the support structure.

[0233] It should be noted that there are several ways to achieve the rotatable connection between the fifth connecting body and the third rotating part, including hinge, shaft connection, and the fit between the arc-shaped guide rail and the arc-shaped guide groove, etc.

[0234] In some embodiments, the base frame assembly is provided with a third connecting protrusion, which has a third sliding groove that slides with the third linkage member. Along the length of the base frame assembly, a third clearance groove is disposed between the third connecting protrusion and the third rotating part. This facilitates connection between the third connecting protrusion and the third linkage member, followed by a rotatable connection between the sixth connecting body and the third linkage member, and finally a rotatable connection between the fifth connecting body and the third rotating part. This streamlines assembly and effectively improves the assembly efficiency of the third linkage member and the third rotating part onto the base frame assembly.

[0235] In some embodiments, the third linkage includes a fifth body (not shown), a sixth body (not shown), and a third guide protrusion (not shown). One end of the fifth body has a fifth connecting portion, and the other end of the fifth body is bent and connected to one end of the sixth body. The other end of the sixth body has a sixth connecting portion, and the third guide protrusion is disposed between the fifth body and the sixth body. Thus, by bending and connecting the fifth and sixth bodies, the fifth and sixth connecting portions can swing relative to the third guide protrusion and slide relative to the base frame assembly with the third guide protrusion. Consequently, the third rotating member can drive the fourth linkage assembly on the other side to rotate via the third linkage. Alternatively, the fourth linkage assembly can drive the third rotating member to rotate via the third linkage.

[0236] In some embodiments, the third rotating member and the fourth rotating member are spaced apart along the length of the base frame assembly. Along the length of the base frame assembly, the third link assembly and the fourth link assembly are disposed between the third rotating member and the fourth rotating member.

[0237] In some embodiments, the third link assembly further includes a third stabilizing member (not shown). The third stabilizing member is rotatably connected to the first side and slidably connected to the third connecting member. The third stabilizing member and the fourth rotating member are spaced apart along the width direction of the base assembly. In this way, the third rotating member and the third stabilizing member rotate synchronously in opposite directions, which enables the third connecting member and the fourth connecting member to be subjected to uniform force during rotation, resulting in smoother movement.

[0238] In some embodiments, the fourth linkage assembly further includes a fourth stabilizing member (not shown). The fourth stabilizing member is rotatably connected to the second side and slidably connected to the fourth connecting member. The fourth stabilizing member and the third rotating member are spaced apart along the width direction of the base assembly. In this way, the fourth rotating member and the third stabilizing member rotate synchronously in opposite directions, which enables the third connecting member and the fourth connecting member to be subjected to uniform force during rotation, resulting in smoother movement.

[0239] like Figure 15 As shown, in some embodiments, the third link assembly 630 includes a seventh link 631. One end of the seventh link 631 is rotatably connected to the base frame assembly 100, and the other end of the seventh link 631 is directly or indirectly rotatably connected to the third connector 250. Thus, during rotation relative to the base frame assembly 100, the third rotating member 610 can drive the third connector 250 to slide along a predetermined direction, and the seventh link 631 can limit the swing direction of the third connector 250, allowing the third connector 250 to switch between a supported state and a folded state.

[0240] like Figure 15 As shown, in some embodiments, the second linkage assembly 340 includes an eighth linkage 641. One end of the eighth linkage 641 is rotatably connected to the sixth connecting portion 720, and the other end of the eighth linkage 641 is directly or indirectly rotatably connected to the fourth connecting member 260. Thus, during the rotation of the fourth rotating member 620 relative to the base frame assembly 100, the fourth connecting member 260 can be driven to slide along a predetermined direction, and the swing direction of the connecting member can be limited by the eighth linkage 641, thereby switching the fourth connecting member 260 between a supported state and a folded state.

[0241] It should be noted that the other end of the seventh link 631 is rotatably connected to the connecting member, either directly or indirectly through other links. The other end of the eighth link 641 is rotatably connected to the connecting member, either directly or indirectly through other links.

[0242] Optionally, the other end of the seventh link 631 is directly rotatably connected to the third connector 250, and the other end of the eighth link 641 is directly rotatably connected to the fourth connector 260. Thus, by the cooperation of the third link assembly 630 and the third rotating member 610 on the first side 110 to form a secondary linkage mechanism, and by the cooperation of the fourth link assembly 640 and the fourth rotating member 620 on the second side 120 to form a secondary linkage mechanism, the hinge mechanism 10b can form a teardrop-shaped clearance space 101 in the folded state, which can meet the bending space required for the flexible display screen 10a to bend, thereby improving the service life of the flexible display screen 10a.

[0243] like Figure 15 As shown, in some embodiments, the third link assembly 630 further includes a ninth link 632 and a tenth link 633. The other end of the seventh link 631 is rotatably connected to the third connector 250 via the ninth link 632. One end of the tenth link 633 is rotatably connected to one end of the seventh link 631 and one end of the third link 632. The other end of the fourth link 333 is rotatably connected to the third rotating member 610. The second link assembly 340 further includes an eleventh link 642 and a twelfth link 643. The other end of the eighth link 641 is rotatably connected to the fourth connector 260 via the eleventh link 642. One end of the twelfth link 643 is rotatably connected to one end of the eighth link 641 and one end of the eleventh link 642. The other end of the twelfth link 643 is rotatably connected to the fourth rotating member 620. Thus, during its rotation relative to the base frame assembly 100, the third rotating member 610 can drive the third connecting member 250 to slide along a predetermined direction. It also cooperates with the third rotating member 610 via the tenth link 633 to restrict the rotational trajectories of the seventh link 631 and the ninth link 632. Furthermore, the seventh link 631 and the ninth link 632 drive the third connecting member 250 to swing along a predetermined trajectory, allowing the third connecting member 250 to switch between a supported state and a folded state. Similarly, during its rotation relative to the base frame assembly 100, the fourth rotating member 620 can drive the fourth connecting member 260 to slide along a predetermined direction. It also cooperates with the fourth rotating member 620 via the twelfth link 643 to restrict the rotational trajectories of the eighth link 641 and the eleventh link 642. Furthermore, the eighth link 641 and the eleventh link 642 drive the fourth connecting member 260 to swing along a predetermined trajectory, allowing the fourth connecting member 260 to switch between a supported state and a folded state.

[0244] Understandably, in conjunction with the appendix Figures 3 to 7As shown, the connection structure between the third linkage and the base frame assembly can be understood by referring to the connection structure between the first linkage and the base frame assembly. The connection structure between the third linkage, the third rotating member, and the fourth link assembly can be understood by referring to the connection structure between the first linkage, the first rotating member, and the second link assembly. That is, as Figures 2 to 11 The hinge mechanism can achieve linkage control on both the first side and the second side, enabling the first connecting member and the second connecting member to move synchronously. And as Figure 15 shown, the hinge mechanism utilizes the third linkage to achieve linkage control on the first side, enabling the first connecting member and the second connecting member to move synchronously.

[0245] As Figure 16 shown, in some embodiments of the hinge mechanism 10b, the base frame assembly 100 includes a first side portion 110 and a second side portion 120 spaced apart from the first side portion 110 in the width direction of the base frame assembly 100. The carrier assembly 200 includes a fifth connecting member 270 disposed close to the first side portion 110 and a sixth connecting member 280 disposed close to the second side portion 120. The link member includes a fifth rotating member 810, a sixth rotating member 820, a fifth link assembly 830, a sixth link assembly 840, and a fourth linkage 850. The fifth link assembly 830 is disposed between the first side portion 110 and the fifth connecting member 270, and the fifth link assembly 830 is rotatably connected to the base frame assembly 100 and rotatably connected to the fifth connecting member 270. The sixth link assembly 840 is disposed between the second side portion 120 and the sixth connecting member 280, and the sixth link assembly 840 is rotatably connected to the base frame assembly 100 and rotatably connected to the sixth connecting member 280. The fifth rotating member 810 is rotatably connected to the first side portion 110 and slidably connected to the fifth connecting member 270. The sixth rotating member 820 is rotatably connected to the second side portion 120 and slidably connected to the sixth connecting member 280. The fourth linkage 850 includes a seventh connecting portion 851, an eighth connecting portion 852, and a fourth limiting structure 853 disposed between the seventh connecting portion 851 and the eighth connecting portion 852. The seventh connecting portion 851 is rotatably connected to the fifth rotating member 810, and the eighth connecting portion 852 is rotatably connected to the sixth link assembly 840. The fourth limiting structure 853 is in limiting cooperation with the base frame assembly 100 for restricting the movement of the fourth linkage 850 relative to the base frame assembly 100 within a preset area.

[0246] During the assembly of the hinge mechanism 10b, the fifth rotating member 810 and the fifth link assembly 830 are rotatably connected to the first side portion 110, and the sixth rotating member 820 and the sixth link assembly 840 are rotatably connected to the second side portion 120. The fourth linkage member 850 is assembled onto the base frame assembly 100 via the fourth limiting structure 853, and is rotatably connected to the fifth rotating member 810 via the seventh connecting portion 851, and rotatably connected to the sixth link assembly 840 via the eighth connecting portion 852. Thus, the fifth rotating member 810 and the sixth link assembly 840 are assembled onto the base frame assembly 100 via the fourth linkage member 850, so that the fifth rotating member 810 can drive the sixth link assembly 840 to move via the fourth linkage member 850, or the sixth link assembly 840 can drive the fifth rotating member 810 to rotate via the fourth linkage member 850. Then, the fifth connector 270 is also assembled onto the first side 110 of the base frame assembly 100 through a slidable connection with the fifth rotating member 810 and a rotatable connection with the fifth link assembly 830. Similarly, the sixth connector 280 is also assembled onto the second side 120 of the base frame assembly 100 through a slidable connection with the sixth rotating member 820 and a rotatable connection with the sixth link assembly 840, so that the fifth connector 270 and the sixth connector 280 can rotate relative to the base frame assembly 100.

[0247] Specifically, the fifth connecting member 270 rotates relative to the base frame assembly 100 via the fifth link assembly 830, thus restricting the rotation trajectory of the fifth connecting member 270. When the fifth rotating member 810 rotates, the fifth connecting member 270 rotates with it, and due to the restriction of the fifth link assembly 830, the fifth connecting member 270 also slides relative to the fifth rotating member 810. That is, the fifth connecting member 270 is assembled onto the base frame assembly 100 via the fifth rotating member 810 and the fifth link assembly 830, allowing the fifth connecting member 270 to move relative to the base frame assembly 100 along a set trajectory. Similarly, the sixth connecting member 280 is assembled onto the base frame assembly 100 via the sixth rotating member 820 and the sixth link assembly 840, allowing the sixth connecting member 280 to move relative to the base frame assembly 100 along a set trajectory.

[0248] For example, during the folding process of the hinge mechanism 10b, the fifth connector 270 rotates relative to the base frame assembly 100 along a set trajectory, causing the fifth rotating member 810 to rotate. Under the constraint of the fifth link assembly 830, the fifth connector 270 slides away from the fifth rotating member 810, thus moving the fifth connector 270 away from the base frame assembly 100 to create more clearance space 101. Similarly, the sixth connector 280 rotates relative to the base frame assembly 100 along a set trajectory, causing the sixth rotating member 820 to rotate. Under the constraint of the sixth link assembly 840, the sixth connector 280 can slide away from the sixth rotating member 820, thus moving the sixth connector 280 away from the base frame assembly 100 to create more clearance space 101.

[0249] For example, during the unfolding of the hinge mechanism 10b, the fifth connecting member 270 rotates relative to the base frame assembly 100 along a predetermined trajectory, causing the fifth rotating member 810 to rotate. Under the constraint of the fifth link assembly 830, the fifth connecting member 270 can slide towards the fifth rotating member 810, thus positioning the fifth connecting member 270 close to the base frame assembly 100 to cooperate with the base frame assembly 100 and form the support structure 102. Similarly, the sixth connecting member 280 rotates relative to the base frame assembly 100 along a predetermined trajectory, causing the sixth rotating member 820 to rotate. Under the constraint of the sixth link assembly 840, the sixth connecting member 280 can slide towards the sixth rotating member 820, thus positioning the sixth connecting member 280 close to the base frame assembly 100 to cooperate with the base frame assembly 100 and form the support structure 102.

[0250] During the rotation of the fifth rotating member 810, it can also drive the fourth linkage member 850 to move within a preset area, thereby pulling the sixth link assembly 840 through the eighth connecting part 852. This, in turn, drives the sixth connecting member 280 and the sixth rotating member 820 of the second side 120 to move, achieving synchronous movement of the fifth connecting member 270 and the sixth connecting member 280, and synchronous rotation of the fifth rotating member 810 and the sixth rotating member 820. During the rotation of the sixth link assembly 840 driven by the sixth connecting member 280, it can also drive the fourth linkage member 850 to move within a preset area, thereby pulling the fifth moving member through the seventh connecting part 851. This, in turn, drives the fifth connecting member 270 and the fifth link assembly 830 of the first side 110 to move, achieving synchronous movement of the fifth connecting member 270 and the sixth connecting member 280, and synchronous rotation of the fifth rotating member 810 and the sixth rotating member 820. Thus, the fifth connector 270 and the sixth connector 280 on both sides of the base frame assembly 100 can move synchronously through the fourth linkage 850. Compared with the gear synchronization structure, it occupies less space, which can improve the compactness of the hinge mechanism 10b and help to achieve the thinner and lighter foldable electronic device 10.

[0251] It should be noted that the fifth rotating member 810 can drive the fourth linkage member 850 to move through various structures, which in turn drive the sixth link assembly 840 to move. For example, an eccentric drive, etc. The sixth link assembly 840 can also drive the fourth linkage member 850 to move through various structures, which in turn drive the fifth rotating member 810 to move. For example, an eccentric drive, etc.

[0252] Reference Figure 16 In some embodiments, the fifth rotating member 810 is rotatably connected to the first side portion 110 and has a seventh rotation axis. The fifth rotating member 810 is also rotatably connected to the seventh connecting portion 851 and has an eighth rotation axis. The seventh and eighth rotation axes are not coaxial. Thus, during the rotation of the fifth rotating member 810, an eccentric driving force is generated to drive the fourth linkage member 850, which in turn drives the sixth linkage assembly 840.

[0253] Furthermore, the sixth link assembly 840 is rotatably connected to the second side portion 120 and has a ninth rotation axis. The sixth link assembly 840 is also rotatably connected to the eighth connecting portion 852 and has a tenth rotation axis. The ninth and tenth rotation axes are not coaxial. Thus, during the rotation of the sixth link assembly 840, an eccentric driving force can be generated to drive the fourth linkage member 850 to move, which in turn drives the fifth rotating member 810 to move via the fourth linkage member 850.

[0254] In one example, the fifth rotating member 810 is rotatably connected to the base frame assembly as shown in the diagram. Figure 16 The large circle shown is the seventh axis of rotation, with its center line being the seventh axis of rotation. A schematic diagram illustrating the rotatable connection between the fifth rotating member 810 and the seventh connecting part 851 is shown below. Figure 16 The small circle shown is centered on the eighth axis of rotation and is offset from the large circle. The fifth rotating component 810 rotates around the center line of the large circle (i.e., the seventh axis of rotation), causing the small circle to move eccentrically.

[0255] The schematic diagram of the rotatable connection between the sixth link assembly 840 and the base frame assembly is as follows: Figure 16 The large circle shown is the ninth rotation axis, with its center line being the ninth rotation axis. A schematic diagram illustrating the rotatable connection between the sixth link assembly 840 and the eighth connecting part 852 is shown below. Figure 16 The small circle shown is centered on the eighth rotation axis and has an eccentricity with the large circle. The sixth link assembly 840 rotates around the center line of the large circle (i.e., the ninth rotation axis), causing the small circle to move eccentrically.

[0256] In some embodiments, the fifth link assembly is also connected to the fifth rotating member via a transmission connection. Thus, during the rotation of the fifth rotating member, in addition to driving the fifth link assembly through the fifth connecting member, it can also directly drive the fifth link assembly to rotate, making the movement of the fifth connecting member smoother.

[0257] Furthermore, the sixth link assembly is also connected to the sixth rotating component via a transmission connection. Similarly, during the rotation of the sixth rotating component, in addition to driving the sixth link assembly through the sixth connecting component, it can also directly drive the sixth link assembly to rotate, making the movement of the sixth connecting component more stable.

[0258] In some embodiments, when the hinge mechanism is in the unfolded state, the support component and the base frame component cooperate to form a support structure to support the flexible display screen. This facilitates the use of the support structure formed by the hinge mechanism in conjunction with the shell body to support the flexible display screen, making it convenient for users to unfold and use the flexible display screen, improving the display quality and user experience of the foldable electronic device. When the hinge mechanism is in the folded state, the support component and the base frame component intersect at an angle to form a clearance space. The flexible display screen can bend within this clearance space, reducing the risk of damage. Simultaneously, the hinge mechanism can also protect the bent portion of the flexible display screen, improving the durability of the foldable electronic device. Furthermore, the hinge mechanism can drive the fifth and sixth connecting components to move synchronously via the fourth linkage, allowing the hinge mechanism to switch between the unfolded and folded states. This results in a more compact structure, which is beneficial for the lightweight design of the hinge mechanism.

[0259] like Figure 17As shown, in another embodiment of the hinge mechanism 10b, the base frame assembly 100 includes a first side portion 110 and a second side portion 120 spaced apart from the first side portion 110 along the width direction of the base frame assembly 100. The load-bearing assembly 200 includes a fifth connector 270 disposed near the first side portion 110 and a sixth connector 280 disposed near the second side portion 120. The linkage components include a seventh rotating member 860, an eighth rotating member 870, a fifth linkage assembly 830, a sixth linkage assembly 840, and a fifth linkage member 880. The fifth linkage assembly 830 is disposed between the first side portion 110 and the fifth connector 270, and is rotatably connected to the base frame assembly 100 and to the fifth connector 270. The sixth linkage assembly 840 is disposed between the second side portion 120 and the sixth connector 280, and is rotatably connected to the base frame assembly 100 and to the sixth connector 280. The seventh rotating member 860 is rotatably connected to the first side portion 110 and slidably connected to the fifth connecting member 270. The eighth rotating member 870 is disposed near the second side portion 120 and slidably connected to the sixth connecting member 280. The fifth linkage member 880 includes a ninth connecting portion 881, a tenth connecting portion 882, and a fifth limiting structure 883 disposed between the ninth connecting portion 881 and the tenth connecting portion 882. The ninth connecting portion 881 is rotatably connected to the eighth rotating member 870, and the tenth connecting portion 882 is rotatably connected to the fifth link assembly 830. The fifth limiting structure 883 is limited in cooperation with the base frame assembly 100 to restrict the movement of the fifth linkage member 880 relative to the base frame assembly 100 within a preset area.

[0260] During the assembly of the hinge mechanism 10b, the seventh rotating member 860 is rotatably connected to the first side portion 110, and the fifth link assembly 830 and the sixth link assembly 840 are respectively assembled onto the base frame assembly 100. The fifth linkage member 880 is assembled onto the base frame assembly 100 via the fifth limiting structure 883, and is rotatably connected to the eighth rotating member 870 via the ninth connecting portion 881. The tenth connecting portion 882 is rotatably connected to the fifth link assembly 830, so that the fifth link assembly 830 can drive the eighth rotating member 870 to rotate via the fifth linkage member 880. Then, the fifth connecting member 270 is also assembled onto the first side portion 110 of the base frame assembly 100 via a sliding connection with the seventh rotating member 860 and a rotatable connection with the fifth link assembly 830. Similarly, the sixth connector 280 is also assembled onto the second side 120 of the base frame assembly 100 through a sliding connection with the eighth rotating member 870 and a rotatable connection with the sixth link assembly 840, so that the fifth connector 270 and the sixth connector 280 can rotate relative to the base frame assembly 100.

[0261] Specifically, the fifth connecting member 270 rotates relative to the base frame assembly 100 via the fifth link assembly 830, thus restricting the rotation trajectory of the fifth connecting member 270. When the seventh rotating member 860 rotates, the fifth connecting member 270 will rotate with the seventh rotating member 860, and due to the restriction of the fifth link assembly 830, the fifth connecting member 270 will also slide relative to the seventh rotating member 860. That is, the fifth connecting member 270 is assembled onto the base frame assembly 100 via the seventh rotating member 860 and the fifth link assembly 830, allowing the fifth connecting member 270 to move relative to the base frame assembly 100 along a set trajectory. Similarly, the sixth connecting member 280 is assembled onto the base frame assembly 100 via the eighth rotating member 870 and the sixth link assembly 840, allowing the sixth connecting member 280 to move relative to the base frame assembly 100 along a set trajectory.

[0262] For example, during the folding process of the hinge mechanism 10b, the fifth connector 270 rotates relative to the base frame assembly 100 along a predetermined trajectory, causing the seventh rotating member 860 to rotate. Under the constraint of the fifth link assembly 830, the fifth connector 270 slides away from the seventh rotating member 860, thus moving the fifth connector 270 away from the base frame assembly 100 to create more clearance space 101. Similarly, the sixth connector 280 rotates relative to the base frame assembly 100 along a predetermined trajectory, causing the eighth rotating member 870 to rotate. Under the constraint of the sixth link assembly 840, the sixth connector 280 can slide away from the eighth rotating member 870, thus moving the sixth connector 280 away from the base frame assembly 100 to create more clearance space 101.

[0263] For example, during the unfolding of the hinge mechanism 10b, the fifth connecting member 270 rotates relative to the base frame assembly 100 along a predetermined trajectory, causing the seventh rotating member 860 to rotate. Under the constraint of the fifth link assembly 830, the fifth connecting member 270 can slide towards the seventh rotating member 860, thus positioning the fifth connecting member 270 close to the base frame assembly 100 to cooperate with the base frame assembly 100 and form the support structure 102. Similarly, the sixth connecting member 280 rotates relative to the base frame assembly 100 along a predetermined trajectory, causing the eighth rotating member 870 to rotate. Under the constraint of the sixth link assembly 840, the sixth connecting member 280 can slide towards the eighth rotating member 870, thus positioning the sixth connecting member 280 close to the base frame assembly 100 to cooperate with the base frame assembly 100 and form the support structure 102.

[0264] As the fifth connecting member 270 drives the fifth link assembly 830 to rotate, it also drives the fifth linkage member 880 to move within a preset area. This, in turn, pulls the eighth moving member through the ninth connecting part 881, thereby driving the sixth connecting member 280 and the sixth link assembly 840 on the second side 120 to move. This achieves synchronous movement of the fifth connecting member 270 and the sixth connecting member 280, and synchronous rotation of the fifth rotating member 810 and the sixth rotating member 820. Thus, the fifth linkage member 880 enables synchronous movement of the fifth connecting member 270 and the sixth connecting member 280 on both sides of the base frame assembly 100. Compared to a gear synchronization structure, this method occupies less space, improving the compactness of the hinge mechanism 10b and facilitating the thinning and lightening of the foldable electronic device 10.

[0265] Reference Figure 17 In some embodiments, the fifth link assembly 830 is rotatably connected to the first side portion 110 and has an eleventh rotation axis. The fifth link assembly 830 is also rotatably connected to the tenth connecting portion 882 and has a twelfth rotation axis. The eleventh and twelfth rotation axes are not coaxial. Thus, during the rotation of the fifth link assembly 830, an eccentric driving force can be generated to drive the fifth linkage member 880, which in turn drives the eighth rotating member 870.

[0266] In one example, the fifth link assembly 830 is rotatably connected to the base frame assembly as shown in the diagram. Figure 17 The large circle shown is the eleventh rotation axis, with its center line being the eleventh rotation axis. A schematic diagram illustrating the rotatable connection between the fifth link assembly 830 and the tenth connecting part 882 is shown below. Figure 17 The small circle shown is centered on the twelfth rotation axis and has an eccentricity with the large circle. The fifth link assembly 8430 rotates around the center line of the large circle (i.e., the eleventh rotation axis), causing the small circle to move eccentrically.

[0267] In some embodiments, the fifth link assembly is also connected to the seventh rotating member via a transmission connection. Thus, during the rotation of the seventh rotating member, in addition to driving the fifth link assembly through the fifth connecting member, it can also directly drive the fifth link assembly to rotate, making the movement of the fifth connecting member smoother.

[0268] Furthermore, the sixth link assembly is also connected to the eighth rotating component via a transmission connection. Similarly, during the rotation of the eighth rotating component, in addition to driving the sixth link assembly through the sixth connecting component, it can also directly drive the sixth link assembly to rotate, making the movement of the sixth connecting component more stable.

[0269] In some embodiments, when the hinge mechanism is in the unfolded state, the support component and the base frame component cooperate to form a support structure to support the flexible display screen. This facilitates the use of the support structure formed by the hinge mechanism in conjunction with the shell body to support the flexible display screen, making it convenient for users to unfold and use the flexible display screen, improving the display quality and user experience of the foldable electronic device. When the hinge mechanism is in the folded state, the support component and the base frame component intersect at an angle to create a clearance space. The flexible display screen can bend within this clearance space, reducing the risk of damage. Simultaneously, the hinge mechanism can also protect the bent portion of the flexible display screen, improving the durability of the foldable electronic device. Furthermore, the hinge mechanism can drive the fifth and sixth connecting components to move synchronously via the fifth linkage, allowing the hinge mechanism to switch between the unfolded and folded states. This results in a more compact structure, which is beneficial for the lightweight design of the hinge mechanism.

[0270] See you later Figure 14 As shown, in conjunction with the hinge mechanism in any of the above embodiments, in some embodiments, the hinge mechanism further includes a damping component 900. The damping component 900 is in damped rotatable engagement with at least one rotating member (e.g., a first rotating member or a second rotating member) and / or at least one linkage assembly (e.g., a first linkage assembly or a second two-bar assembly). Thus, by providing the damping component, each linkage component can be damped and rotatably connected to the base frame assembly, preventing the foldable electronic device from easily rotating, facilitating the support or constraint of the flexible display screen, and making it convenient to use. It also facilitates the use of each linkage assembly to constrain the movement of the support plate, improving the motion accuracy of the hinge mechanism.

[0271] It should be noted that the damping component can be installed on any rotating component in the hinge mechanism, as long as it meets the above requirements.

[0272] It should be noted that there are other ways to implement the "damping component". For example, friction plates can be used to increase the rotational friction of the linkage assembly; or elastic elements can be used to increase the rotational resistance of the linkage assembly; or magnetic elements can be used to increase the rotational resistance of the linkage assembly, etc.

[0273] It should be noted that "hovering" can be understood as the ability of a rotating component to remain in a certain position when no driving force is applied. Applying a certain rotational force to the rotating component allows it to rotate, while removing or reducing this force causes it to remain stationary in that position. This applies to the linkage assembly and / or the linkage assembly and its connection to the base frame assembly.

[0274] Understandably, the damping assembly includes a locked state and a hovering state. When the damping assembly is in the locked state, the linkage assembly can be locked in the unfolded and / or folded state, facilitating the restraint of the support plate. When the damping assembly is in the hovering state, the linkage assembly can be locked in the hovering state during the transition between unfolded and folded states, and can also be used to restrain the rotation of the support plate. The rotational resistance of the hinge mechanism when the damping assembly is in the locked state is greater than the rotational resistance of the hinge mechanism when the damping assembly is in the hovering state.

[0275] In conjunction with any of the above embodiments, in some embodiments, the hinge mechanism can be suspended at any angle within the range of 0° to 180°. Thus, the hinge mechanism can hover within the range of 45° to 135°, defined as a hovering state. In the hovering state, the hinge mechanism can rotate and stop instantly, facilitating the use of foldable electronic devices from multiple angles and improving the user experience.

[0276] In any embodiment of the rotating component described above, the hovering rotation range of the rotating component in any embodiment is A, where A ≥ 50°. Thus, this rotation range can be flexibly set according to actual needs. For example, A = 50°, 60°, 90°, 100°, 110°, 120°, 130°, 150°, etc.

[0277] like Figures 2 to 6 As shown, in some embodiments, the first rotating member 310 and / or the second rotating member 320 can be suspended and rotated so that the corresponding hinge mechanism 10b can be suspended at any angle within the range of 0° to 180°. In this case, the rotating member can also be referred to as a synchronizing rod.

[0278] Similarly, in some embodiments, the third and / or fourth rotating members can be suspended and rotated so that the corresponding hinge mechanism can be suspended at any angle within the range of 0° to 180°. In this case, the rotating members can also be referred to as synchronizing rods.

[0279] Similarly, in some embodiments, the fifth and / or sixth rotating members can be suspended and rotated so that the corresponding hinge mechanism can be suspended at any angle within the range of 0° to 180°. In this case, the rotating members can also be referred to as synchronizing rods.

[0280] Similarly, in some embodiments, the seventh and / or eighth rotating members can be suspended and rotated so that the corresponding hinge mechanism can be suspended at any angle within the range of 0° to 180°. In this case, the rotating members can also be referred to as synchronizing rods.

[0281] Optionally, in some embodiments, the base frame assembly includes a base frame body (not shown) and a decorative shell (not shown) fixedly connected to the base frame body, the length direction of the decorative shell being arranged in the same direction as the length direction of the support plate. Thus, the decorative shell can both protect the hinge mechanism and cooperate with the shell body, enhancing the aesthetic appearance of the foldable electronic device.

[0282] Optionally, in some embodiments, the base frame assembly further includes a support plate (not shown) disposed on the base frame body. This facilitates the use of support plates in conjunction to form a support structure or clearance space. Furthermore, the support plate, in conjunction with the decorative shell, provides better protection for connecting rod components and linkages.

[0283] It should be noted that "set at an angle" includes acute angles, right angles, and obtuse angles, but does not include straight angles.

[0284] Furthermore, this foldable electronic device utilizes the hinge mechanism found in any of the aforementioned embodiments and is connected to the shell body via a support component. This allows the support component to unfold or fold the shell body and the flexible display screen covering it. During this process, the hinge mechanism occupies minimal space.
