Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of electronic technology, and in particular, to a rotating component, a hinge mechanism and a foldable electronic device. BACKGROUND

[0002] Electronic devices such as mobile phones and tablets have become an indispensable technology product in people's life, learning and entertainment process. At present, the flexible display screen of the foldable electronic device can be conveniently carried after being folded. And the flexible display screen has a larger display area after being unfolded, so that the foldable electronic device is more and more favored by consumers.

[0003] In the related art, the foldable electronic device usually utilizes a hinge mechanism to realize the unfolding or folding of the flexible display screen. However, the conventional hinge mechanism usually needs to utilize a gear structure to realize rotation, but the gear transmission scheme occupies a larger space, which is not conducive to improving the compactness of the hinge mechanism. SUMMARY

[0004] The present disclosure provides a rotating component, a hinge mechanism and a foldable electronic device. The rotating component can switch between an unfolded state and a folded state, and occupies a small space, which is conducive to improving the compactness of the hinge mechanism and realizing the thinness of the foldable electronic device.

[0005] The technical scheme is as follows:

[0006] According to a first aspect of the embodiments of the present disclosure, a rotating component is provided, comprising a mounting piece, a first rotating piece, a second rotating piece and a stop rod. The mounting piece comprises a first mounting portion and a second mounting portion arranged along the first mounting portion at intervals. The first rotating piece is rotationally connected with the first mounting portion. The second rotating piece is rotationally connected with the second mounting portion. A transmission assembly is slidingly connected with the mounting piece and is in transmission cooperation with the first rotating piece and the second rotating piece respectively, so as to make the first rotating piece and the second rotating piece rotate in opposite directions.

[0007] The technical scheme provided by the embodiments of the present disclosure can include the following beneficial effects:

[0008] In the process of switching the rotating component from the unfolded state to the folded state, the first rotating member rotates and drives the second rotating member to rotate reversely through the transmission assembly, so that the first rotating member and the second rotating member are close to each other, and the folding of the rotating component is realized. And / or, the second rotating member rotates and drives the first rotating member to rotate reversely through the transmission assembly, so that the first rotating member and the second rotating member are close to each other, and the folding of the rotating component is realized. When the rotating component needs to be switched from the folded state to the unfolded state, the first rotating member rotates and drives the second rotating member to rotate reversely through the transmission assembly, so that the first rotating member and the second rotating member are far away from each other, and the unfolding of the rotating component is realized. And / or, the second rotating member rotates and drives the first rotating member to rotate reversely through the transmission assembly, so that the first rotating member and the second rotating member are far away from each other, and the unfolding of the rotating component is realized. In this process, the transmission assembly is in sliding connection with the mounting member, and the space occupied is small. Further, the rotating component can be switched between the unfolded state and the folded state, and the space occupied is small, which is beneficial to improve the compactness of the hinge mechanism and realize the thinness of the foldable electronic device.

[0009] The technical solutions of the present disclosure are further described below:

[0010] In one of the embodiments, the transmission assembly includes a first push rod, and the first push rod is in sliding connection with the mounting member. When the first rotating member rotates in the process of switching the rotating component from the unfolded state to the folded state, the second rotating member can be driven to rotate reversely through the first push rod. When the second rotating member rotates in the process of switching the rotating component from the folded state to the unfolded state, the first rotating member can be driven to rotate reversely through the first push rod.

[0011] And / or, the transmission assembly includes a second push rod, and the second push rod is in sliding connection with the mounting member. When the second rotating member rotates in the process of switching the rotating component from the unfolded state to the folded state, the first rotating member can be driven to rotate reversely through the second push rod. When the first rotating member rotates in the process of switching the rotating component from the folded state to the unfolded state, the second rotating member can be driven to rotate reversely through the second push rod.

[0012] In one of the embodiments, the first push rod includes a first sliding body in sliding connection with the mounting member and a first abutting body avoiding the first rotating member, one end of the first sliding body is in bent connection with one end of the first abutting body, so that the other end of the first abutting body is arranged above the first sliding body and abuts against the first rotating member. The other end of the first sliding body abuts against the second rotating member.

[0013] When the rotating component switches from the unfolded state to the folded state, the first rotating component, when rotating, can push against the other end of the first abutment body, thereby pushing the second rotating component to rotate in the opposite direction through the other end of the first sliding body. When the rotating component switches from the folded state to the unfolded state, the second rotating component, when rotating, can push against the other end of the first sliding body, thereby pushing the second rotating component to rotate in the opposite direction through the other end of the first abutment body.

[0014] In one embodiment, the mounting member is provided with a first sliding groove that slides with the first sliding body and a first clearance groove for avoiding the first abutting body.

[0015] In one embodiment, the first mounting part is provided with a first mounting groove communicating with the first clearance groove, and the first rotating member is provided with a first rotating body rotatably engaged with the first mounting groove. The first rotating body is provided with a first mating groove communicating with the first clearance groove and a first protrusion fixed in the first mating groove. The first protrusion abuts against the other end of the first abutting body. When the rotating member switches from the unfolded state to the folded state, the first rotating member rotates and can push against the other end of the first abutting body through the first protrusion.

[0016] And / or, the second mounting part is provided with a second mounting groove communicating with the first sliding groove, and the second rotating member is provided with a second rotating body rotatably engaged with the second mounting groove. The second rotating body is provided with a second mating groove communicating with the first sliding groove and a second protrusion fixed in the second mating groove. The second protrusion abuts against the other end of the first sliding body. When the rotating member switches from the folded state to the unfolded state, the second rotating member rotates and can push against the other end of the first sliding body through the second protrusion.

[0017] In one embodiment, the first rotating body is cylindrical.

[0018] And / or, the rotating component further includes a first rotating shaft, which is rotatably connected to the first rotating body and the first mounting portion.

[0019] In one embodiment, the second rotating body is cylindrical.

[0020] And / or, the rotating component further includes a second rotating shaft, which is rotatably connected to the second rotating body and the second mounting portion.

[0021] In one embodiment, the second push rod includes a second sliding body slidably connected to the mounting member and a second abutting body that avoids the second rotating member. One end of the second sliding body is bent and connected to one end of the second abutting body. The other end of the second abutting body is disposed above the second sliding body and abuts against the second rotating member. The other end of the second sliding body abuts against the first rotating member.

[0022] When the rotating component switches from the unfolded state to the folded state, the rotation of the second rotating member pushes against the other end of the second abutment, thereby pushing the first rotating member to rotate in the opposite direction through the other end of the second sliding body. When the rotating component switches from the folded state to the unfolded state, the rotation of the first rotating member pushes against the other end of the second sliding body, thereby pushing the second rotating member to rotate in the opposite direction through the other end of the second abutment.

[0023] In one embodiment, the mounting member is provided with a second sliding groove that slides with the second sliding body and a second clearance groove for avoiding the second abutment body. One end of the second sliding groove is connected to the second clearance groove, and the other end of the second sliding groove is connected to the first rotating member.

[0024] In one embodiment, the first mounting part has a first mounting groove communicating with the second sliding groove, the first rotating member has a first rotating body rotatably engaged with the first mounting groove, the first rotating body has a third mating groove communicating with the second sliding groove and a third protrusion fixed in the third mating groove, the third protrusion abutting against the other end of the second sliding body. When the rotating member switches from the unfolded state to the folded state, the first rotating member rotates and can push against the other end of the second sliding body through the third protrusion.

[0025] And / or, the second mounting part is provided with a second mounting groove communicating with the second clearance groove, and the second rotating member is provided with a first rotating body rotatably engaged with the second mounting groove. The first rotating body is provided with a fourth mating groove communicating with the second clearance groove and a fourth protrusion fixed in the fourth mating groove. The fourth protrusion abuts against the other end of the second abutment body. When the rotating member switches from the folded state to the unfolded state, the second rotating member rotates and can push against the other end of the second abutment body through the fourth protrusion.

[0026] In one embodiment, the transmission assembly includes a connecting rod-slider assembly that is slidably connected to a mounting member, one end of which is movably connected to a first rotating member, and the other end of which is movably connected to a second rotating member.

[0027] During the process of switching the rotating component from a folded state to an unfolded state, the rotation of the first rotating component can push the second rotating component to rotate in the opposite direction via the linkage slider assembly. Conversely, during the process of switching the rotating component from an unfolded state to a folded state, the rotation of the first rotating component can pull the second rotating component to rotate in the opposite direction via the linkage slider assembly.

[0028] During the transition from a folded to an unfolded state, the rotation of the second rotating component can, via the linkage and slider assembly, pull the first rotating component to rotate in the opposite direction. Similarly, during the transition from an unfolded to a folded state, the rotation of the second rotating component can, via the linkage and slider assembly, push the first rotating component to rotate in the opposite direction.

[0029] In one embodiment, the linkage slider assembly includes a first slide rod slidably connected to a mounting member, a first transmission rod connected to one end of the first slide rod, and a second transmission rod connected to the other end of the first slide rod. The first transmission rod is drive-connected to a first rotating member, and the second transmission rod is drive-connected to a second transmission member.

[0030] According to a second aspect of the present disclosure, a hinge mechanism is also provided, including a base frame assembly, connectors, and a rotating component as described in any of the above embodiments. The base frame assembly is fixedly connected to a mounting component. Two connectors are provided, one of which is slidably connected to a first rotating component, and the other connector is slidably connected to a second rotating component.

[0031] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0032] During assembly, the hinge mechanism is fixedly connected to the base frame assembly via mounting components, facilitating the assembly of the rotating parts onto the base frame assembly. Simultaneously, one connecting part is slidably connected to the first rotating part, and the other connecting part is slidably connected to the second rotating part. This allows the rotating parts to fold or unfold the two connecting parts. When folding is required, the first rotating part rotates, driving the second rotating part to rotate in the opposite direction via the transmission assembly, bringing the first and second rotating parts closer together, thus bringing the two connecting parts closer together and achieving folding. Alternatively, the second rotating part rotates, driving the first rotating part to rotate in the opposite direction via the transmission assembly, bringing the first and second rotating parts closer together, thus bringing the two connecting parts closer together and achieving folding. When switching from a folded to an unfolded state, the first rotating part rotates, driving the second rotating part to rotate in the opposite direction via the transmission assembly, moving the first and second rotating parts away from each other, thus moving the two connecting parts away from each other and achieving unfolding. Or, the second rotating component rotates, and through the transmission assembly, drives the first rotating component to rotate in the opposite direction, so that the first and second rotating components move away from each other, thereby causing the two connecting components to move away from each other and achieving unfolding. During this process, the transmission assembly is slidably connected to the mounting component, occupying little space. This allows the hinge mechanism to switch between unfolded and folded states while maintaining a compact size, which is beneficial for achieving a thinner and lighter foldable electronic device.

[0033] The technical solution of this disclosure will be further explained below:

[0034] In one embodiment, the hinge mechanism further includes floats and second linkage assemblies. Two floats are included, each rotatably connected to a corresponding connector. Two second linkage assemblies are also included; one second linkage assembly has one end rotatably connected to the base frame assembly and the other end rotatably connected to a corresponding connector. The other second linkage assembly has one end rotatably connected to the base frame assembly and the other end rotatably connected to a corresponding connector.

[0035] When the hinge mechanism is in the deployed state, the float plate cooperates with the base frame assembly and / or mounting components to form a support structure.

[0036] When the hinge mechanism is in the folded state, the float is set at an angle to the base frame assembly and cooperates with the base frame assembly and / or mounting parts to form a receiving space.

[0037] In one embodiment, the second linkage assembly includes a first linkage, one end of which is rotatably connected to the base frame assembly, and the other end of which is rotatably connected to the connector.

[0038] In one embodiment, the second linkage assembly includes a first linkage, a second linkage, and a third linkage. One end of the first linkage is rotatably connected to the base frame assembly, and the other end of the first linkage is rotatably connected to one end of the second linkage and one end of the third linkage. The other end of the second linkage is rotatably connected to a connector. In one set of second linkage assemblies, the other end of the third linkage is rotatably connected to a first rotating member, and in another set of second linkage assemblies, the other end of the third linkage is rotatably connected to a second rotating member.

[0039] According to a third aspect of the present 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 above embodiments. The housing assembly includes a housing body, which is fixedly connected to a connector. The flexible display screen covers at least a portion of the housing assembly.

[0040] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0041] This foldable electronic device utilizes the hinge mechanism found in any of the above embodiments and connects to the shell body via a connector, enabling the connector to unfold or fold the shell body and the flexible display screen covering it. During this process, the transmission component and the mounting component are slidably connected, resulting in a small footprint. Consequently, this foldable electronic device boasts a highly compact structure, facilitating the miniaturization and lightening of foldable electronic devices.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] Based on this, the present disclosure provides a rotating component 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.

[0068] To better understand the rotating component of this disclosure, it will be illustrated by using a foldable electronic device incorporating the rotating component.

[0069] like Figures 1 to 3 As shown, in an embodiment 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. The hinge mechanism 10b includes a rotating component 100, a base frame assembly 200, and a connector 300.

[0070] Among them, such as Figures 4 to 1 1 b As shown, the rotating component 100 includes a mounting member 110, a first rotating component 120, a second rotating component 130, and a stop rod. The mounting member 110 includes a first mounting portion 111 and a second mounting portion 112 spaced apart from the first mounting portion 111. The first rotating component 120 is rotatably connected to the first mounting portion 111. The second rotating component 130 is rotatably connected to the second mounting portion 112. The transmission assembly 140 is slidably connected to the mounting member 110 and engages with both the first rotating component 120 and the second rotating component 130 to cause them to rotate in opposite directions. Thus, the slidable connection between the transmission assembly 140 and the mounting member 110 achieves the opposite rotation of the first rotating component 120 and the second rotating component 130, occupying a small space. This allows the rotating component 100 to switch between an unfolded state and a folded state while maintaining a small space footprint, which improves the compactness of the hinge mechanism 10b.

[0071] See you later Figure 2 as well as Figure 3 As shown, the base frame assembly 200 is fixedly connected to the mounting member 110. Two connectors 300 are included, one of which is slidably connected to the first rotating member 120, and the other connector 300 is slidably connected to the second rotating member 130.

[0072] like Figures 4 to 1 1 bAs shown, during the assembly of the hinge mechanism 10b, it is fixedly connected to the base frame assembly 200 via the mounting part 110, facilitating the assembly of the rotating part 100 onto the base frame assembly 200. Simultaneously, one connecting part 300 is slidably connected to the first rotating part 120, and the other connecting part 300 is slidably connected to the second rotating part 130. This allows the rotating part 100 to drive the two connecting parts 300 to fold or unfold. When folding is required, the first rotating part 120 rotates, and through the transmission assembly 140, drives the second rotating part 130 to rotate in the opposite direction, bringing the first rotating part 120 and the second rotating part 130 closer together, thereby bringing the two connecting parts 300 closer together and achieving folding. Alternatively, the second rotating part 130 rotates, and through the transmission assembly 140, drives the first rotating part 120 to rotate in the opposite direction, bringing the first rotating part 120 and the second rotating part 130 closer together, thereby bringing the two connecting parts 300 closer together and achieving folding. When the two connecting pieces 300 need to switch from a folded state to an unfolded state, the first rotating piece 120 rotates, and through the transmission assembly 140, drives the second rotating piece 130 to rotate in the opposite direction, so that the first rotating piece 120 and the second rotating piece 130 move away from each other, thereby causing the two connecting pieces 300 to move away from each other and achieve unfolding. Alternatively, the second rotating piece 130 rotates, and through the transmission assembly 140, drives the first rotating piece 120 to rotate in the opposite direction, so that the first rotating piece 120 and the second rotating piece 130 move away from each other, thereby causing the two connecting pieces 300 to move away from each other and achieve unfolding. During this process, the transmission assembly 140 is slidably connected to the mounting piece 110, occupying little space. This allows the hinge mechanism 10b to switch between unfolded and folded states while occupying little space, improving the compactness of the hinge mechanism 10b.

[0073] Furthermore, see you again Figure 1 as well as Figure 2 As shown, the housing assembly 10c includes a housing body 103, which is fixedly connected to the connector 300. The flexible display screen 10a covers at least a portion of the housing assembly 10c. The connector 300 connects to the housing body 103, allowing the connector 300 to unfold or fold the housing body 103 and the flexible display screen 10a covering it. This foldable electronic device 10 utilizes the hinge mechanism 10b from any of the above embodiments and connects to the housing body 103 via the connector 300, enabling the connector 300 to unfold or fold the housing body 103 and the flexible display screen 10a covering it. During this process, the transmission assembly 140 is slidably connected to the mounting member 110, occupying minimal space. Thus, the foldable electronic device 10 has a highly compact structure, facilitating the thinning and lightening of the foldable electronic device 10.

[0074] Understandably, compared with gear transmission, the transmission assembly 140 and the mounting part 110 are slidably connected, requiring no clearance, and the fit between the two is small, resulting in a compact structure.

[0075] Furthermore, compared to gear drives, the transmission assembly 140 is easier to make thinner and can be embedded within the mounting member 110, resulting in a compact connection structure between the transmission assembly 140 and the mounting member 110 with a small footprint. In particular, the small footprint of the mounting member allows for thinner rotating parts 100 and base frame assembly 200, facilitating the miniaturization of the foldable electronic device 10.

[0076] Furthermore, the rotating component 100 of this application can provide a new technical solution that is different from gear transmission, realizing the associated rotation of the first rotating component 120 and the second rotating component 130, which can reduce the assembly difficulty of the rotating component 100 and provide more possibilities for the design of the hinge mechanism 10b.

[0077] Optionally, the first mounting portion 111 and the second mounting portion 112 are spaced apart along the width direction of the mounting member 110.

[0078] like Figure 4 As shown, the width direction of the mounting member 110, i.e., the Y-axis direction, is aligned with the length direction of the foldable electronic device 10. The length direction of the mounting member 110, i.e., the X-axis direction, is also spaced apart and aligned with the width direction of the foldable electronic device 10.

[0079] Optionally, such as Figure 4 As shown, in some embodiments, the thickness direction of the mounting component 110, the thickness direction of the base frame assembly 200, the thickness direction of the hinge mechanism 10b, and the thickness direction of the foldable electronic device 10 in its unfolded state are the Z-axis direction.

[0080] It should be noted that there are multiple ways to implement the "drive connection between the stop rod and the first rotating member 120", including indirect drive and direct drive. As long as the rotational force of the first rotating member 120 can be used to drive the stop rod to extend or retract.

[0081] like Figure 4 , Figure 5 , Figure 6 as well as Figures 8a to 9b As shown, in some embodiments, the transmission assembly 140 includes a first push rod 141, which is slidably connected to the mounting member 110. When the rotating component 100 switches from an unfolded state to a folded state, the rotation of the first rotating component 120 can push the second rotating component 130 to rotate in the opposite direction via the first push rod 141. Conversely, when the rotating component 100 switches from a folded state to an unfolded state, the rotation of the second rotating component 130 can push the first rotating component 120 to rotate in the opposite direction via the first push rod 141.

[0082] Thus, by utilizing the transmission cooperation between the first push rod 141, the first transmission component, and the second transmission component, during the process of switching the rotating component 100 from the unfolded state to the folded state, the first rotating component 120 rotates, and through the first push rod 141, pushes the second rotating component 130 to rotate in the opposite direction, so that the first rotating component 120 and the second rotating component 130 move closer to each other (i.e., move towards each other), thereby achieving the folding of the rotating component 100. When the rotating component 100 needs to switch from the folded state to the unfolded state, the second rotating component 130 rotates, and through the first push rod 141, drives the first rotating component 120 to rotate in the opposite direction, so that the first rotating component 120 and the second rotating component 130 move away from each other (i.e., move in opposite directions), thereby achieving the unfolding of the rotating component 100. During this process, the first push rod 141 is slidably connected to the mounting component 110, and its space occupation is small. This allows the rotating component 100 to switch between the unfolded and folded states, and its small space occupation is beneficial to improving the compactness of the hinge mechanism 10b and realizing the thinness and lightness of the foldable electronic device 10.

[0083] Furthermore, such as Figure 4 , Figure 5 , Figure 6 as well as Figures 8a to 9b As shown, in some embodiments, the first push rod 141 includes a first sliding body 1411 slidably connected to the mounting member 110 and a first abutment body that avoids the first rotating member 120. One end of the first sliding body 1411 is bent and connected to one end of the first abutment body, so that the other end of the first abutment body is positioned above the first sliding body 1411 and abuts against the first rotating member 120. The other end of the first sliding body 1411 abuts against the second rotating member 130. When the rotating member 100 switches from the unfolded state to the folded state, when the first rotating member 120 rotates, it can push against the other end of the first abutment body, so as to push the second rotating member 130 to rotate in the opposite direction through the other end of the first sliding body 1411. When the rotating member 100 switches from the folded state to the unfolded state, when the second rotating member 130 rotates, it can push against the other end of the first sliding body 1411, so as to push the second rotating member 130 to rotate in the opposite direction through the other end of the first abutment body.

[0084] Thus, by having the first abutment body avoid and abut against the first rotating member 120, the first push rod 141 will not interfere with the rotation of the first rotating member 120. The first sliding body 1411 abuts against the second rotating member 130, so when the second rotating member 130 rotates from the unfolded state to the folded state, the second rotating member 130 cannot pull the first sliding body 1411 to rotate. At this time, when the rotating component 100 switches from the unfolded state to the folded state, the first rotating member 120 pushes against the first abutment body, and the first sliding body 1411 pushes against the second rotating member 130, so that the first rotating member 120 drives the second rotating member 130 to move in the opposite direction, so that the first rotating member 120 and the second rotating member 130 move closer to each other (i.e., move towards each other), thus realizing the folding of the rotating component 100. Because the first abutment body abuts against the first rotating member 120, the first rotating member 120 cannot pull the first abutment body when it rotates from the folded state to the unfolded state. When the rotating component 100 needs to switch from a folded state to an unfolded state, the second rotating component 130 rotates, and by pushing against the first sliding body 1411, the first pushing body 1412 pushes the first rotating component 120 to rotate in the opposite direction, so that the first rotating component 120 and the second rotating component 130 move away from each other (i.e., move in opposite directions), thus unfolding the rotating component 100. During this process, the first sliding body 1411 is slidably connected to the mounting component 110, and the first abutting body also abuts against the first rotating component 120, making the space occupied by the rotating component 100 small.

[0085] like Figure 4 , Figure 5 , Figure 6 as well as Figures 8a to 9b As shown, in some embodiments, the mounting member 110 is provided with a first sliding groove 113 that slides with the first sliding body 1411 and a first clearance groove 114 for avoiding the first abutment. One end of the first sliding groove 113 communicates with the first clearance groove 114, and the other end of the first sliding groove 113 leads to the second rotating member 130. Thus, by sliding with the first sliding body 1411 through the first sliding groove 113, the first push rod 141 and the mounting member 110 are slidably connected. By providing the first clearance groove 114, the mounting member 110 does not interfere with the movement of the first abutment, thereby ensuring reliable transmission of the first push rod 141 and enabling the first rotating member 120 and the second rotating member 130 to rotate in opposite directions.

[0086] like Figure 4 , Figure 5 , Figure 6 as well as Figures 8a to 9bAs shown, in some embodiments, the first mounting part 111 is provided with a first mounting groove 1111 communicating with the first clearance groove 114, and the first rotating member 120 is provided with a first rotating body 121 rotatably engaged with the first mounting groove 1111. The first rotating body 121 is provided with a first mating groove 1211 communicating with the first clearance groove 114 and a first protrusion 1212 fixed in the first mating groove 1211. The first protrusion 1212 abuts against the other end of the first abutment. When the rotating member 100 switches from the unfolded state to the folded state, the first rotating member 120 rotates and can push against the other end of the first abutment through the first protrusion 1212. Thus, through the rotational engagement of the first mounting groove 1111 and the first rotating body 121, the first rotating member 120 and the mounting member 110 are tightly engaged. At the same time, by providing the first mating groove 1211 on the first rotating body 121 to cooperate with the first clearance groove 114 to form a larger clearance space to avoid the movement of the first abutment. Moreover, the first abutting body is partially disposed within the first mating groove 1211, making full use of the internal space of the first rotating member 120 to accommodate part of the first push rod 141, so that the two fit tightly and improve the structural compactness of the rotating member 100.

[0087] Furthermore, the first protrusion 1212 abuts against the other end of the first abutting body, so that the first rotating member 120 can accurately push the first abutting body to move through the first protrusion 1212, and the transmission is reliable.

[0088] In some embodiments, the first rotating body 121 is cylindrical. That is, the first rotating body 121 is shaped like a pivot, which allows for a tighter fit with the first mounting groove 1111.

[0089] like Figure 4 , Figures 5 to 6 As shown, in some embodiments, the rotating component 100 further includes a first rotating shaft 150, which is rotatably connected to the first rotating body 121 and the first mounting portion 111. Thus, by rotatably connecting the first rotating shaft 150 to the first rotating body 121 and the first mounting portion 111, the first rotating component 120 is reliably connected to the mounting portion 110.

[0090] Optionally, such as Figure 5 As shown, in some embodiments, the first mounting portion 111 includes first lugs 1112 spaced apart to form first mounting grooves 1111. The first lugs 1112 and the first rotating body 121 are provided with first connecting holes for connection with the first rotating shaft 150. Thus, the first rotating body 121 is inserted into the first mounting groove 1111, and then sequentially inserted into the first connecting holes through the first rotating shaft 150, so that the first rotating body 121 and the first lugs 1112 are reliably connected, and the first rotating body 121 is embedded in the mounting member 110 through the first mounting groove 1111, so that the first rotating member 120 and the mounting member 110 fit tightly.

[0091] like Figure 4 , Figure 5 , Figure 6 as well as Figures 8a to 9b As shown, in some embodiments, the second mounting part 112 is provided with a second mounting groove 1121 communicating with the first sliding groove 113, and the second rotating member 130 is provided with a second rotating body 131 rotatably engaged with the second mounting groove 1121. The second rotating body 131 is provided with a second mating groove 1311 communicating with the first sliding groove 113 and a second protrusion 1312 fixed in the second mating groove 1311. The second protrusion 1312 abuts against the other end of the first sliding body 1411. When the rotating member 100 switches from the folded state to the unfolded state, the second rotating member 130 rotates and can push against the other end of the first sliding body 1411 through the second protrusion 1312. In this way, through the rotational engagement of the second mounting groove 1121 and the second rotating body 131, the second rotating member 130 and the mounting member 110 are tightly engaged. Meanwhile, by providing a second mating groove 1311 on the first rotating body 121 to cooperate with the second mounting groove 1121 to accommodate the first sliding body 1411, the internal space of the second rotating member 130 and the internal space of the mounting member 110 can be fully utilized to accommodate part of the first push rod 141, so that the two fit tightly and improve the structural compactness of the rotating component 100.

[0092] Furthermore, the second protrusion 1312 abuts against the other end of the first sliding body 1411, so that the second rotating member 130 can accurately push the first sliding body 1411 to move through the second protrusion 1312, and the transmission is reliable.

[0093] In some embodiments, the second rotating body 131 is cylindrical. That is, the second rotating body 131 is shaped like a pivot, allowing for a tighter fit with the second mounting groove 1121.

[0094] like Figures 4 to 6 As shown, in some embodiments, the rotating component 100 further includes a second rotating shaft 160, which is rotatably connected to the second rotating body 131 and the second mounting portion 112. Thus, by rotatably connecting the second rotating shaft 160 to the second rotating body 131 and the second mounting portion 112, the connection between the second rotating component 130 and the mounting portion 110 is reliable.

[0095] Optionally, such as Figure 5As shown, in some embodiments, the second mounting portion 112 includes second lugs 1122 spaced apart to form a second mounting groove 1121. The second lugs 1122 and the second rotating body 131 are provided with second connecting holes for connection with the second rotating shaft 160. Thus, the second rotating body 131 is inserted into the second mounting groove 1121, and then sequentially inserted into the second connecting holes via the second rotating shaft 160, so that the second rotating body 131 and the second lugs 1122 are reliably connected, and the second rotating body 131 is embedded in the mounting member 110 through the second mounting groove 1121, so that the second rotating member 130 and the mounting member 110 fit tightly.

[0096] In combination with any of the above embodiments, such as Figure 4 , Figure 5 , Figure 7 as well as Figures 10a to 1 1 b As shown, in some embodiments, the transmission assembly 140 includes a second push rod 142, which is slidably connected to the mounting member 110. When the rotating component 100 switches from an unfolded state to a folded state, the rotation of the second rotating component 130 can push the first rotating component 120 to rotate in the opposite direction via the second push rod 142. Conversely, when the rotating component 100 switches from a folded state to an unfolded state, the rotation of the first rotating component 120 can push the second rotating component 130 to rotate in the opposite direction via the second push rod 142.

[0097] Thus, by utilizing the transmission cooperation between the second push rod 142 and the first and second transmission components, during the transition of the rotating component 100 from the unfolded state to the folded state, the second rotating component 130 rotates, and through the second push rod 142, pushes the first rotating component 120 to rotate in the opposite direction, so that the first rotating component 120 and the second rotating component 130 move closer to each other (i.e., move towards each other), thereby achieving the folding of the rotating component 100. When the rotating component 100 needs to transition from the folded state to the unfolded state, the first rotating component 120 rotates, and through the second push rod 142, drives the second rotating component 130 to rotate in the opposite direction, so that the first rotating component 120 and the second rotating component 130 move away from each other (i.e., move in opposite directions), thereby achieving the unfolding of the rotating component 100. During this process, the second push rod 142 is slidably connected to the mounting component 110, and its space occupation is small. This allows the rotating component 100 to switch between the unfolded and folded states, and its small space occupation is beneficial to improving the compactness of the hinge mechanism 10b and achieving the thinness and lightness of the foldable electronic device 10.

[0098] like Figure 4 , Figure 5 , Figure 7 as well as Figures 10a to 1 1 bAs shown, in some embodiments, the second push rod 142 includes a second sliding body 1421 slidably connected to the mounting member 110 and a second abutment body 1422 that avoids the second rotating member 130. One end of the second sliding body 1421 is bent and connected to one end of the second abutment body 1422. The other end of the second abutment body 1422 is disposed above the second sliding body 1421 and abuts against the second rotating member 130. The other end of the second sliding body 1421 abuts against the first rotating member 120. When the rotating member 100 switches from the unfolded state to the folded state, the second rotating member 130 rotates and can push against the other end of the second abutment body 1422, so as to push the first rotating member 120 to rotate in the opposite direction through the other end of the second sliding body 1421. When the rotating member 100 switches from the folded state to the unfolded state, the first rotating member 120 rotates and can push against the other end of the second sliding body 1421, so as to push the second rotating member 130 to rotate in the opposite direction through the other end of the second abutment body 1422.

[0099] Thus, by having the second abutment 1422 avoid and abut against the second rotating member 130, the second push rod 142 will not interfere with the rotation of the second rotating member 130. The second sliding body 1421 engages with the first rotating member 120, so when the first rotating member 120 rotates from the unfolded state to the folded state, the first rotating member 120 cannot pull the second sliding body 1421 to rotate. At this time, when the rotating component 100 switches from the unfolded state to the folded state, the second rotating member 130 pushes against the second abutment 1422, and the second sliding body 1421 pushes against the first rotating member 120, so that the second rotating member 130 drives the first rotating member 120 to move in the opposite direction, so that the first rotating member 120 and the second rotating member 130 move closer to each other (i.e., move towards each other), thus realizing the folding of the rotating component 100. Because the second abutment 1422 abuts against the second rotating member 130, the second rotating member 130 cannot pull the second abutment 1422 when rotating from the folded state to the unfolded state. At this time, when the rotating member 100 needs to switch from the folded state to the unfolded state, the first rotating member 120 rotates and pushes against the second sliding member 1421. The second pushing member pushes the second rotating member 130 to rotate in the opposite direction, so that the first rotating member 120 and the second rotating member 130 move away from each other (i.e., move in opposite directions), thus unfolding the rotating member 100. During this process, the second sliding member 1421 is slidably connected to the mounting member 110, and the second abutment 1422 also abuts against the second rotating member 130, making the space occupied by the rotating member 100 small.

[0100] like Figure 4 , Figure 5 , Figure 7 as well as Figures 10a to 1 1 bAs shown, in some embodiments, the mounting member 110 is provided with a second sliding groove 115 that slides with the second sliding body 1421 and a second clearance groove 116 for avoiding the second abutment body 1422. One end of the second sliding groove 115 communicates with the second clearance groove 116, and the other end of the second sliding groove 115 leads to the first rotating member 120. Thus, the sliding connection between the second push rod 142 and the mounting member 110 is achieved through the sliding engagement of the second sliding groove 115 and the second sliding body 1421. By providing the second clearance groove 116, the mounting member 110 will not interfere with the movement of the second abutment body 1422, thereby ensuring reliable transmission of the second push rod 142 and enabling the first rotating member 120 and the second rotating member 130 to rotate in opposite directions.

[0101] like Figure 4 , Figure 5 , Figure 7 as well as Figures 10a to 1 1 b As shown, in some embodiments, the first mounting part 111 is provided with a first mounting groove 1111 communicating with the second slide groove 115, and the first rotating member 120 is provided with a first rotating body 121 rotatably engaged with the first mounting groove 1111. The first rotating body 121 is provided with a third mating groove 1213 communicating with the second slide groove 115 and a third protrusion 1214 fixed in the third mating groove 1213. The third protrusion 1214 abuts against the other end of the second sliding body 1421. When the rotating member 100 switches from the unfolded state to the folded state, the first rotating member 120 rotates and can push against the other end of the second sliding body 1421 through the third protrusion 1214. In this way, through the rotational engagement of the first mounting groove 1111 and the first rotating body 121, the first rotating member 120 and the mounting member 110 are tightly engaged. Meanwhile, by providing a third mating groove 1213 on the first rotating body 121 to cooperate with the first mounting groove 1111 to accommodate the second sliding body 1421, the internal space of the first rotating part 120 and the internal space of the mounting part 110 can be fully utilized to accommodate part of the second push rod 142, so that the two fit tightly and improve the structural compactness of the rotating part 100.

[0102] Furthermore, the third protrusion 1214 abuts against the other end of the second sliding body 1421, so that the first rotating member 120 can accurately push the second sliding body 1421 to move through the third protrusion 1214, and the transmission is reliable.

[0103] like Figure 4 , Figure 5 , Figure 7 as well as Figures 10a to 1 1 bAs shown, in some embodiments, the second mounting portion 112 is provided with a second mounting groove 1121 communicating with the second clearance groove 116, and the second rotating member 130 is provided with a first rotating body 121 rotatably engaged with the second mounting groove 1121. The first rotating body 121 is provided with a fourth mating groove 1313 communicating with the second clearance groove 116 and a fourth protrusion 1314 fixed in the fourth mating groove 1313. The fourth protrusion 1314 abuts against the other end of the second abutment 1422. When the rotating member 100 switches from a folded state to an unfolded state, the second rotating member 130 rotates and can push against the other end of the second abutment 1422 through the fourth protrusion 1314. Thus, through the rotational engagement of the second mounting groove 1121 and the second rotating body 131, the second rotating member 130 and the mounting member 110 are tightly engaged. Meanwhile, a fourth mating groove 1313 is provided on the second rotating body 131 to cooperate with the second clearance groove 116 to form a larger clearance space to avoid the movement of the second abutment 1422. Moreover, part of the second abutment 1422 is disposed in the second mating groove 1311, making full use of the internal space of the second rotating member 130 to accommodate part of the second push rod 142, so that the two fit tightly and improve the structural compactness of the rotating component 100.

[0104] Furthermore, the fourth protrusion 1314 abuts against the other end of the second abutment 1422, so that the second rotating member 130 can accurately push the second abutment 1422 to move through the fourth protrusion 1314, and the transmission is reliable.

[0105] like Figures 4 to 1 1 b As shown, in conjunction with the embodiments of the first push rod 141 and the second push rod 142 described above, the transmission assembly 140 includes a first push rod 141 and a second push rod 142. The first push rod 141 is slidably connected to the mounting member 110, and one end of the first push rod 141 abuts against the first rotating member 120, while the other end of the first push rod 141 abuts against the second transmission member. The second push rod 142 is slidably connected to the mounting member 110, and one end of the second push rod 142 abuts against the first rotating member 120, while the other end of the second push rod 142 abuts against the second transmission member.

[0106] During the transition from the unfolded state to the folded state of the rotating component 100, when the first rotating component 120 rotates, it can push the second rotating component 130 to rotate in the opposite direction via the first push rod 141. When the second rotating component 130 rotates, it can push the first rotating component 120 to rotate in the opposite direction via the second push rod 142. That is, regardless of whether force is applied to rotate the first rotating component 120 or the second rotating component 130, the first rotating component 120 and the second rotating component 130 can rotate synchronously to achieve synchronous folding of the two connecting components 300, thereby driving the flexible display screens 10a on both sides of the hinge mechanism 10b to fold synchronously.

[0107] During the transition from the folded to the unfolded state of the rotating component 100, when the second rotating component 130 rotates, it can push the first rotating component 120 to rotate in the opposite direction via the first push rod 141. When the first rotating component 120 rotates, it can push the second rotating component 130 to rotate in the opposite direction via the second push rod 142. And when the second rotating component 130 rotates, it can push the first rotating component 120 to rotate in the opposite direction via the second push rod 142. That is, regardless of whether force is applied to rotate the first rotating component 120 or the second rotating component 130, the first rotating component 120 and the second rotating component 130 can rotate synchronously to achieve synchronous unfolding of the two connected components, thereby driving the flexible display screens 10a on both sides of the hinge mechanism 10b to unfold synchronously.

[0108] like Figure 13 As shown, in some embodiments, the transmission assembly 140 includes a linkage-slider assembly 143, which is slidably connected to the mounting member 110. One end of the linkage-slider assembly 143 is movably connected to the first rotating member 120, and the other end is movably connected to the second rotating member 130. When the rotating member 100 switches from a folded state to an unfolded state, the rotation of the first rotating member 120 can push the second rotating member 130 to rotate in the opposite direction via the linkage-slider assembly 143. Similarly, when the rotating member 100 switches from an unfolded state to a folded state, the rotation of the first rotating member 120 can pull the second rotating member 130 to rotate in the opposite direction via the linkage-slider assembly 143. Finally, when the rotating member 100 switches from a folded state to an unfolded state, the rotation of the second rotating member 130 can pull the first rotating member 120 to rotate in the opposite direction via the linkage-slider assembly 143. When the rotating component 100 switches from the unfolded state to the folded state, the second rotating component 130 rotates, which can push the first rotating component 120 to rotate in the opposite direction through the connecting rod slider assembly 143.

[0109] During the assembly of the hinge mechanism 10b, it is fixedly connected to the base frame assembly 200 via the mounting part 110, facilitating the assembly of the rotating part 100 onto the base frame assembly 200. Simultaneously, one connecting part 300 is slidably connected to the first rotating part 120, and the other connecting part 300 is slidably connected to the second rotating part 130. This allows the rotating part 100 to drive the two connecting parts 300 to fold or unfold. When folding is required, the first rotating part 120 rotates, pushing the second rotating part 130 to rotate in the opposite direction via the connecting rod slider assembly 143, bringing the first rotating part 120 and the second rotating part 130 closer together, thereby bringing the two connecting parts 300 closer together and achieving folding. Similarly, the second rotating part 130 rotates, pulling the first rotating part 120 to rotate in the opposite direction via the connecting rod slider assembly 143, bringing the first rotating part 120 and the second rotating part 130 closer together, thereby bringing the two connecting parts 300 closer together and achieving folding. When the two connecting pieces 300 need to switch from a folded state to an unfolded state, the first rotating piece 120 rotates, and through the connecting rod slider assembly 143, pulls the second rotating piece 130 to rotate in the opposite direction, so that the first rotating piece 120 and the second rotating piece 130 move away from each other, thereby causing the two connecting pieces 300 to move away from each other and achieve unfolding. The second rotating piece 130 rotates, and through the connecting rod slider assembly 143, pushes the first rotating piece 120 to rotate in the opposite direction, so that the first rotating piece 120 and the second rotating piece 130 move away from each other, thereby causing the two connecting pieces 300 to move away from each other and achieve unfolding. During this process, at least a portion of the connecting rod slider assembly 143 is slidably connected to the mounting piece 110, and it occupies little space. This allows the hinge mechanism 10b to switch between unfolded and folded states, while occupying little space, thus improving the compactness of the hinge mechanism 10b.

[0110] It should be noted that there are multiple ways to implement the connecting rod and slider assembly 143, as long as it can drive the first rotating member 120 and the second rotating member 130 to rotate synchronously.

[0111] For example, such as Figure 13 As shown, in some embodiments, the linkage slider assembly 143 includes a first slide rod 1431 slidably connected to the mounting member 110, a first transmission rod 1432 connected to one end of the first slide rod 1431, and a second transmission rod 1433 connected to the other end of the first slide rod 1431. The first transmission rod 1432 is drivenly connected to the first rotating member 120, and the second transmission rod 1433 is drivenly connected to the second transmission member.

[0112] See you later Figure 2 as well as Figure 3As shown, in some embodiments, the hinge mechanism 10b further includes a float plate 400 and a second link assembly 500. Two float plates 400 are included, each rotatably connected to a corresponding connector 300. Two second link assemblies 500 are included; one end of one second link assembly 500 is rotatably connected to the base frame assembly 200, and the other end is rotatably connected to the corresponding connector 300. One end of the other second link assembly 500 is rotatably connected to the base frame assembly 200, and the other end is rotatably connected to the corresponding connector 300. When the hinge mechanism 10b is in the unfolded state, the float plate 400 cooperates with the base frame assembly 200 and / or the mounting member 110 to form a support structure 102. When the hinge mechanism 10b is in the folded state, the float plate 400 is angled to the base frame assembly 200 and cooperates with the base frame assembly 200 and / or the mounting member 110 to form a receiving space 101.

[0113] When the foldable electronic device 10 is in use, if the flexible display screen 10a needs to be unfolded, the hinge mechanism 10b is switched to the unfolded state, at least utilizing the floating plate 400 to cooperate with the base frame assembly 200 and / or mounting member 110 to form a support structure 102. This allows the support structure 102 and the shell body 103 to more comprehensively support the flexible display screen 10a, improving display quality and facilitating user operation. When the flexible display screen 10a is folded, the hinge mechanism 10b switches from the unfolded state to the folded state. During this process, the second linkage assembly 500 and the first rotating member 120 rotate along the base frame assembly 200. The second linkage assembly 500 drives the connecting member 300 to rotate, causing the connecting member 300 to slide against the first rotating member 120. This allows the connecting member 300 to move the floating plate 400 away from the base frame assembly 200, creating space for the flexible display screen 10a to bend. This facilitates the use of at least the floating plate 400 in conjunction with the base frame assembly 200 and / or the mounting component 110 to form a receiving space 101, thereby better protecting the bent portion of the flexible display screen 10a.

[0114] In some embodiments, portions of the float plate 400, the base frame assembly 200, the rotating component 100, and the second linkage assembly 500 cooperate to form a support structure 102. When the hinge mechanism 10b is in the folded state, the float plate 400 and the base frame assembly 200 are arranged at an angle, and portions of the float plate 400, the base frame assembly 200, the rotating component 100, and the second linkage assembly 500 cooperate to form a receiving space 101.

[0115] It should be noted that the mating structure between the second linkage assembly 500 and the rotating component 100 can be varied, including but not limited to two-stage linkage mechanisms, three-stage linkage mechanisms, four-stage linkage mechanisms, etc. In this process, one of the linkages can be defined as the driving element, driving the moving component to move.

[0116] In some embodiments, such as Figure 2 as well as Figure 3 As shown. Or, as Figure 14 As shown, the second linkage assembly 500 includes a first linkage 510. One end of the first linkage 510 is rotatably connected to the base frame assembly 200, and the other end is rotatably connected to the connector 300. The rotating member is rotatably connected to the base frame assembly 200 and slidably connected to the connector 300. Thus, during its rotation relative to the base frame assembly 200, the rotating member can drive the connector 300 to slide along a predetermined direction of the rotating member, and the first linkage 510 restricts the swing direction of the connector 300, thereby switching the float 400 between a supported state and a folded state.

[0117] It should be noted that the other end of the first link 510 is rotatably connected to the connector 300, including direct connection or indirect connection through other links.

[0118] Optionally, such as Figure 14 As shown, the other end of the first link 510 is directly rotatably connected to the connector 300. Thus, in combination with the aforementioned two sets of support plates, a two-stage linkage mechanism is formed by the cooperation of the first link 510 and the rotating component. This allows the hinge mechanism 10b to form a teardrop-shaped receiving 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.

[0119] In other embodiments, such as Figure 2 as well as Figure 3As shown, the second linkage assembly 500 includes a first link 510, a second link 520, and a third link 530. One end of the first link 510 is rotatably connected to the base frame assembly 200, and the other end of the first link 510 is rotatably connected to one end of the second link 520 and one end of the third link 530. The other end of the second link 520 is rotatably connected to the connector 300. In one set of the second linkage assemblies 500, the other end of the third link 530 is rotatably connected to the first rotating member 120, and in another set of the second linkage assemblies 500, the other end of the third link 530 is rotatably connected to the second rotating member 130. Thus, the first link 510, the first rotating member 120, the second link 520, and the third link 530 cooperate to form a three-stage linkage mechanism, and the first link 510, the second rotating member 130, the second link 520, and the third link 530 cooperate to form another three-stage linkage mechanism. During the process of limiting the swing of the connector 300 by the first link 510 and the second link 520, the connector 300 and the floating plate 400 can move further away from the first support member. This makes the teardrop-shaped receiving 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 to protect the flexible display screen 10a in the folded state.

[0120] In other embodiments, the second linkage assembly 500 further includes at least one link disposed between the first link 510 and the second link 520 to form a four-stage linkage mechanism, a five-stage linkage mechanism, etc.

[0121] On the longitudinal projection plane of the base frame assembly 200, when the hinge mechanism 10b is in the folded state, the width of the accommodating space 101 gradually increases from the base frame assembly 200 to the other end of the first link 510, and gradually decreases from one end of the third link 530 to the other end of the second link 520. Thus, the accommodating space 101 gradually increases to reduce stress concentration. The gradual decrease in width from one end of the second link 520 to the other end allows the flexible display screen 10a to gradually conform away from the base frame assembly 200. This facilitates the thinning and lightening of the foldable electronic device 10, and also allows the flexible display screen 10a to bend smoothly, improving its bending lifespan.

[0122] In conjunction with any of the above embodiments, in some embodiments, the hinge mechanism 10b can be suspended at any angle within the range of 45° to 135°. Thus, the hinge mechanism 10b can hover within the range of 45° to 135°, defined as a hovering state. In the hovering state, the hinge mechanism 10b can rotate and stop instantly, facilitating the use of the foldable electronic device 10 from multiple angles and improving the user experience of the foldable electronic device 10.

[0123] In any embodiment of the rotating component described above, the hovering rotation range of the rotating component 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.

[0124] In some embodiments, the rotating element can be suspended to rotate, so that the hinge mechanism 10b can be suspended at any angle within the range of 45° to 135°. In this case, the rotating element can also be referred to as a synchronizing rod.

[0125] The rotating component includes at least one of a first rotating component 120 and a second rotating component 130.

[0126] In some embodiments, the housing assembly 10c includes a decorative shell (not shown), the length direction of which is aligned with the length direction of the first support member, and the decorative shell is fixedly connected to the first support member. Thus, the decorative shell can both protect the hinge mechanism 10b and cooperate with the housing body 103, enhancing the aesthetic appearance of the foldable electronic device 10.

[0127] Based on any embodiment of the connector 300 described above, such as Figure 14 As shown, in some embodiments, the hinge mechanism 10b further includes a damping component, which engages with the rotating component 100 and / or the second linkage assembly 500 in a damped rotational manner. Thus, by providing the damping component, the first rotating component 120 and the second rotating component 130 can be damped and rotatably connected to the base frame assembly 200, preventing the foldable electronic device 10 from easily rotating, facilitating support or restraint of the flexible display screen 10a, and making it convenient to use.

[0128] It should be noted that the damping component can be installed on either the rotating component 100 or the second link assembly 500, as long as it meets the above requirements.

[0129] It should be noted that the "damping component" can also be implemented in other ways, such as using friction plates to increase the rotational friction of the second link assembly 500; or using elastic elements to increase the rotational resistance of the second link assembly 500; or using magnetic elements to increase the rotational resistance of the second link assembly 500, etc.
