Description

Technical Field

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

[0002] With the continuous development of electronic device technology, multifunctional terminal electronic products are increasingly favored by people. Openable electronic devices such as laptops and tablets with stands are characterized by their thinness, portability, and multifunctionality, making them suitable for various scenarios including entertainment and office work, and are becoming increasingly popular with consumers.

[0003] Openable electronic devices typically include a hinge mechanism. This mechanism acts as a bridge connecting the two housings of the electronic device, enabling rotational engagement between them and allowing the device to open and close, thus meeting the usage needs of the device in various scenarios. For example, taking a laptop as an example, the electronic device may include a display and a keyboard. The display and keyboard are connected by a hinge mechanism, allowing the display to rotate relative to the keyboard, thus opening and closing the device. The hinge mechanism often uses a solid hinge design, such as a cylindrical hinge that can be mounted on the display. The keyboard may have a hinge hole, allowing the display to engage with the keyboard. However, solid hinges and hinge holes occupy a lot of space and can raise the display during rotation, affecting the overall appearance and aesthetics of the electronic device. Another example is a tablet computer with a stand. The tablet may include a main body and a stand. The main body has a display screen on one side, and the stand can be located on the side of the main body away from the display screen. One end of the stand engages with the main body via a hinge mechanism, allowing the stand to rotate relative to the main body, thus opening and closing the stand and the main body. To meet the minimalist design requirements of tablet computers, the hinge mechanism is usually a structural component that rotates around a virtual axis, without physical hinges, shaft holes, or other structures, thus reducing the space occupied by the hinge mechanism.

[0004] However, the rotation mechanism using a virtual axis is difficult to provide stable rotational torque, which affects the opening, closing and hovering effects and reduces the opening and closing experience. Summary of the Invention

[0005] This application provides a pivot mechanism and an electronic device that can provide stable torque, ensure the opening, closing and hovering effect of the electronic device, improve the opening and closing experience, and help improve the overall appearance of the electronic device in the open and closed state, thus enhancing the aesthetics of the electronic device.

[0006] A first aspect of this application provides a rotating shaft mechanism, including a first rotating assembly and a second rotating assembly. The first rotating assembly has a plurality of first friction elements, and the second rotating assembly has a plurality of second friction elements. The plurality of first friction elements and the plurality of second friction elements are staggered along a first direction.

[0007] Adjacent first and second friction components have a first sliding structure, which includes a slidingly fitted first arc-shaped groove and a first arc-shaped slider. The first and second friction components are slidably connected through the first sliding structure. This allows multiple first and second friction components to rotate relative to each other, thereby enabling a first rotating assembly and a second rotating assembly to rotate in conjunction. The axis of relative rotation between the first and second rotating assemblies is the axis of rotation of the first arc-shaped slider relative to the first arc-shaped groove; that is, the axis of rotation is a straight line passing through the center of the first arc-shaped groove and parallel to a first direction. The axis of rotation is not located on the physical structure of the rotating shaft mechanism but outside the physical structure; it is a virtual axis, meaning the first and second rotating assemblies rotate relative to each other around this virtual axis. The rotating shaft mechanism does not contain physical shafts, shaft holes, or other structures, reducing the space occupied by the rotating shaft mechanism.

[0008] The placement of the hinge mechanism within the electronic device is also quite flexible, with minimal constraints on the layout between the hinge mechanism's rotation axis and the housing. For example, the virtual axis of the hinge mechanism can be located at the seam between the first and second housings of the electronic device, such as at the seam between the edges of the second and first housings. This minimizes the seam size, allowing the second housing to fit more closely to the first housing, and minimizing the change in seam width during rotation (i.e., during the opening and closing of the electronic device). Furthermore, the closer proximity of the virtual axis to the second housing results in a smaller radius of rotation for the second housing relative to the first housing, and less noticeable lifting of the second housing relative to the first housing in the thickness direction during opening and closing. When the electronic device is in the open state, the separation between the first and second housings is minimized, enhancing the aesthetics and overall integrity of the electronic device.

[0009] The rotating shaft mechanism also includes a torque structure, which presses against the first and second rotating components along a first direction, increasing the friction between the first and second friction elements. When the first and second rotating components rotate relative to each other, the friction between the first and second friction elements can serve as rotational torque, providing stable torque for the rotation of the first and second rotating components. This meets the torque requirements during the opening and closing process of the electronic device, ensuring the opening, closing, and hovering effects of the electronic device and improving the opening and closing experience.

[0010] In one possible implementation, the first rotating assembly further includes a first fixing member, and the second rotating assembly further includes a second fixing member. A second sliding structure is provided between the first fixing member and the second fixing member. The second sliding structure includes a second arc-shaped groove and a second arc-shaped slider that are in sliding engagement. The first fixing member and the second fixing member are rotatably connected through the second sliding structure, so that the first fixing member and the second fixing member achieve rotational engagement through the second sliding structure.

[0011] The second sliding structure improves the rotational stability of the first and second fixed components, increases the contact friction area between them, and enhances the rotational friction between the first and second rotating components, ensuring the shaft mechanism provides stable torque. The torque structure, by pressing the first and second rotating components along the first direction, also presses the first and second fixed components, further increasing rotational friction.

[0012] In one possible implementation, the first fixing member includes a first mating part and a second mating part, the second fixing member includes a third mating part and a fourth mating part, the first mating part, the second mating part, the third mating part and the fourth mating part are distributed along a first direction, the third mating part and the fourth mating part are located between the first mating part and the second mating part, a plurality of first friction members and a plurality of second friction members are located between the third mating part and the fourth mating part, and a second sliding structure is respectively provided between the first mating part and the third mating part and between the second mating part and the fourth mating part.

[0013] The first fixing member is split into two parts: a first mating part and a second mating part. The second fixing member is split into a third mating part and a fourth mating part, so that the first mating part and the third mating part slide together, and the second mating part and the fourth mating part slide together. This helps to further increase the frictional contact area between the first rotating component and the second rotating component, provide more stable torque, and facilitate assembly with the first friction component and the second friction component.

[0014] In one possible implementation, among a plurality of staggered first friction elements and a plurality of second friction elements, one of the first friction elements is disposed adjacent to a third mating portion, and another of the first friction elements is disposed adjacent to a fourth mating portion.

[0015] The third mating part and one of the first friction elements, and the fourth mating part and the other of the first friction elements, each have a third sliding structure. The third sliding structure includes a third arc-shaped groove and a third arc-shaped slider for sliding fit. The third mating part is rotatably connected to one of the first friction elements through the third sliding structure, and the fourth mating part is rotatably connected to the other of the first friction elements through the third sliding structure.

[0016] The third sliding structure further increases the contact friction area between the first and second rotating components, enhancing their rotational friction and ensuring high stability and strength of the torque of the shaft mechanism, thus improving the opening, closing, and hovering effects of the electronic device. The torque structure, by pressing the first and second rotating components along the first direction, also presses the third mating part and the first friction element, as well as the fourth mating part and the first friction element, increasing rotational friction.

[0017] In one possible implementation, the rotating shaft mechanism further includes a first adapter and a second adapter, with the first adapter provided between the first mating part and the third mating part, and the second adapter provided between the second mating part and the fourth mating part.

[0018] The first mating part and the first adapter, the first adapter and the third mating part, the second mating part and the second adapter, and the second adapter and the fourth mating part each have a second sliding structure.

[0019] When the rotating shaft mechanism switches from the open state to the closed state, causing the electronic device to switch from the closed state to the open state, the second fixing member rotates relative to the first fixing member. The third and fourth mating parts can rotate relative to the first and second adapters, respectively, and the first and second adapters can rotate relative to the first and second mating parts, respectively. This increases the rotatable trajectory of the third and fourth mating parts relative to the second and first mating parts. For example, with a smaller design size for the second arc-shaped slide groove, a larger rotational trajectory can be obtained. This allows for a larger relative rotation angle between the second and first fixing members, enabling the electronic device to have a larger opening angle and facilitating a reduction in the size of the rotating shaft mechanism.

[0020] In addition, the arrangement of the first and second adapters helps to increase the rotational friction of the first and second rotating components, which in turn helps to increase the torque of the rotating shaft mechanism, ensuring that the rotating shaft mechanism can provide stable torque for the opening and closing of the electronic device.

[0021] In one possible implementation, the rotating shaft mechanism further includes a third adapter and a fourth adapter. The third adapter is provided between the third mating part and one of the first friction members, and the fourth adapter is provided between the fourth mating part and the other of the first friction members. A third sliding structure is provided between the third mating part and the third adapter, between the third adapter and one of the first friction members, between the fourth mating part and the fourth adapter, and between the fourth adapter and the other of the first friction members.

[0022] By using the third and fourth adapters, the rotational trajectories of the third and fourth mating parts relative to the first and second friction components can be increased. Even with a smaller design size for the third arc-shaped groove, a larger rotational trajectory can be achieved, allowing the electronic device to have a larger opening angle while reducing the size of the rotating shaft mechanism. Furthermore, it can further increase the frictional force between the first and second rotating components during relative rotation, enhancing the torque of the rotating shaft mechanism.

[0023] In one possible implementation, a plurality of fifth adapters are also included, with a fifth adapter between adjacent first and second friction members, and a first sliding structure between the first friction member and the fifth adapter, and between the fifth adapter and the second friction member.

[0024] The fifth adapter increases the relative rotation trajectory of the first and second friction components. Even with a relatively small design size for the first arc-shaped slide groove, a larger rotation trajectory can be achieved, ensuring a greater opening angle for the electronic device. This facilitates the miniaturization of the shaft mechanism and allows for further increases in its torque.

[0025] In one possible implementation, multiple fifth adapters are connected in sequence, with the first adapter connected to the third adapter, the third adapter connected to a fifth adapter adjacent to the third adapter, a fifth adapter adjacent to the fourth adapter connected to the fourth adapter, and the fourth adapter connected to the second adapter.

[0026] By connecting the first adapter, the third adapter, multiple fifth adapters, the fourth adapter, and the second adapter together, the risk of each adapter detaching from the rotating shaft mechanism during the rotation of the first and second rotating assemblies is reduced or avoided. Furthermore, it allows all the aforementioned adapters to rotate synchronously, improving the opening and closing effect.

[0027] In one possible implementation, the first adapter is plugged into the third adapter via a first connector, and the third adapter is plugged into the adjacent fifth adapter via a second connector. Two adjacent fifth adapters are plugged into each other via third connectors. The fourth adapter is plugged into the adjacent fifth adapter via a fourth connector, and the second adapter is plugged into the fourth adapter via a fifth connector. This plug-in connection method ensures the stability of each connector and facilitates assembly.

[0028] In the first connector, third connector, multiple fifth connectors, fourth connector, and second connector arranged sequentially along the first direction, adjacent connectors are staggered in the first direction. That is, the projections of any two adjacent connectors in the first direction do not overlap, thus creating a certain space between the two connectors to avoid the third mating part, the first friction part, the second friction part, and the fourth mating part, respectively. This improves the integration of the rotating shaft mechanism and facilitates its miniaturization.

[0029] In one possible implementation, the third mating part has a first clearance groove for avoiding the first connector; one of the first friction members adjacent to the third mating part has a second clearance groove for avoiding the second connector; and another of the first friction members adjacent to the fourth mating part has a third clearance groove for avoiding the fourth connector. Each second friction member and the remaining first friction members each have a fourth clearance groove for avoiding the third connector, and the fourth mating part has a fifth clearance groove for avoiding the fifth connector. This improves the compactness of the layout of the structural components within the rotating shaft mechanism, facilitates the miniaturization of the rotating shaft mechanism, and avoids the arrangement of the connectors affecting the rotation of the second rotating assembly relative to the first rotating assembly.

[0030] In one possible implementation, the first fixing member further includes a first mounting portion and a second mounting portion. The first mounting portion is connected to a first mating portion, and the second mounting portion is connected to the second mating portion. The first mounting portion and the second mounting portion can be respectively assembled with the first housing of the electronic device. The first mounting portion and the first mating portion can be integral structural components, and the second mounting portion and the second mating portion can also be integral structural components, further simplifying the structural design and reducing the size of the rotating shaft mechanism.

[0031] The second fixing component also includes a third mounting part and a fourth mounting part. The third mounting part is connected to the third mating part, and the fourth mounting part is connected to the fourth mating part. The second mounting part and the third mounting part can be assembled with the second housing of the electronic device, thereby realizing the assembly of the rotating shaft mechanism with the electronic device. The third mounting part and the third mating part can be integral structural components, and the fourth mounting part and the fourth mating part can also be integral structural components, further simplifying the structural design of the rotating shaft mechanism.

[0032] The first rotating assembly further includes a first connecting rod, with its two ends respectively inserted into a first mounting portion and a second mounting portion. Multiple first friction elements pass through the first connecting rod, allowing the first fixing member and the multiple first friction elements to be connected together via the first connecting rod. The second rotating assembly further includes a second connecting rod, with its two ends respectively inserted into a third mounting portion and a fourth mounting portion. Multiple second friction elements pass through the second connecting rod, allowing the second fixing member and the multiple second friction elements to be connected together via the second connecting rod. This allows the second fixing member and the multiple second friction elements to rotate synchronously relative to the first fixing member and the multiple first friction elements, ensuring the relative rotation of the first and second rotating assemblies around a virtual axis and guaranteeing the opening and closing effect of the electronic device.

[0033] In one possible implementation, an outer appearance component is also included, which has a cavity with one end open, and at least a portion of the first mating part, a portion of the second mating part, a portion of the first friction element, a portion of the second friction element, a portion of the third mating part, and a portion of the fourth mating part are located within the cavity, further improving the compactness of the layout of the rotating shaft mechanism.

[0034] The outer part is rotatably connected to the first and second mating parts. When the second rotating assembly rotates relative to the first rotating assembly, the outer part rotates relative to the first rotating assembly. That is, when the electronic device switches from a closed state to an open state, the second rotating assembly rotates relative to the first rotating assembly, and the outer part also rotates relative to the first rotating assembly. The outer part can cover the rotating shaft mechanism, improve the aesthetics of the rotating shaft mechanism, and thus improve the aesthetics of the electronic device when it is in the open state.

[0035] In one possible implementation, the exterior component includes a first housing portion, a first assembly portion, and a second assembly portion. The first housing portion has a cavity, and the first assembly portion and the second assembly portion are respectively disposed on two opposing inner sidewalls of the first housing portion along a first direction.

[0036] The first assembly part and the first mating part, and the second assembly part and the second mating part, each have a fourth sliding structure. The fourth sliding structure includes a fourth arc-shaped groove and a fourth arc-shaped slider. The first mating part is rotatably connected to the first assembly part through the fourth sliding structure, and the second mating part is rotatably connected to the second assembly part through the fourth sliding structure.

[0037] The fourth sliding structure enables rotational engagement between the outer part and the first rotating component, and also increases the friction between the outer part and the first rotating component during the opening and closing of the shaft mechanism, which helps to further improve the torque of the shaft mechanism and enable the shaft mechanism to provide a more stable torque.

[0038] In one possible implementation, the first housing portion includes an arcuate bottom wall, a first side wall, and a second side wall, the first side wall and the second side wall being located on opposite sides of the arcuate bottom wall along a first direction, and the arcuate bottom wall, the first side wall and the second side wall forming a cavity.

[0039] The first and second sidewalls each have a protruding limiting portion, and the first and second assembly portions each have a limiting groove, into which the limiting portion is inserted. The insertion and engagement of the limiting groove and the limiting portion can limit the rotation between the first assembly portion and the first housing portion, ensuring that the entire appearance component can rotate relative to the first rotating assembly.

[0040] The limiting part has an assembly groove, and the bottom wall of the limiting groove has a protruding insertion part. The insertion part can be inserted into the assembly groove, so that the first assembly part and the second assembly part can be respectively inserted into the first side wall and the second side wall.

[0041] In one possible implementation, the appearance component includes an arc-shaped bottom wall, a first side wall, and a second side wall. The first side wall and the second side wall are located on opposite sides of the arc-shaped bottom wall along a first direction. The arc-shaped bottom wall, the first side wall, and the second side wall form a cavity. A third assembly part and a fourth assembly part are respectively provided on the first side wall and the second side wall.

[0042] The side of the third assembly part facing the arc-shaped bottom wall is an arc-shaped surface, which allows an arc-shaped space to be formed between the third assembly part and the arc-shaped bottom wall. The first mating part is located between the third assembly part and the arc-shaped bottom wall, allowing the first mating part to slide within the arc-shaped space, thereby achieving rotational mating between the first mating part and the exterior part.

[0043] The side of the fourth assembly part facing the curved bottom wall is also curved, and the gap between the fourth assembly part and the curved bottom wall can also form a curved space, allowing the fourth mating part to rotate with the exterior component. This achieves a rotational fit between the exterior component and the first rotating assembly. The exterior component has a simple structural design, which facilitates production and assembly, and also benefits the miniaturization design of the rotating shaft mechanism.

[0044] In one possible implementation, at least one of the first, second, third, fourth, and fifth adapters has an abutment portion on each of its opposite ends along the rotation direction.

[0045] The outer part has a first abutting surface and a second abutting surface, which are located on opposite sides of the open end of the outer part, respectively. The abutting parts abut against the first abutting surface and the second abutting surface, respectively. When the second rotating assembly rotates relative to the first rotating assembly, the second rotating assembly can drive each adapter to rotate relative to the first rotating assembly. The adapters can drive the outer part to rotate together through the abutting parts, so that the outer part also rotates relative to the first rotating assembly.

[0046] In one possible implementation, the torsion structure is located within the exterior components, which helps to improve the overall integrity and aesthetics of the pivot mechanism.

[0047] The torsion structure includes a first elastic element, a first mounting element, and a second mounting element. The first elastic element is located between the first and second mounting elements, with its two ends respectively mounted on the first and second mounting elements. The first mounting element, the first elastic element, and the second mounting element are located between adjacent first and second friction elements. The first elastic element can be assembled using the first and second mounting elements. The first elastic element can push the structural components in the rotating shaft mechanism through the first and second mounting elements, causing the structural components located on both sides of the torsion structure in the rotating shaft mechanism to be tightly pressed together, enabling the rotating shaft mechanism to provide smooth torque.

[0048] In one possible implementation, the first mounting member and the adjacent first friction member, and the second mounting member and the adjacent second friction member, each have a fifth sliding structure. The fifth sliding structure includes a fifth arc-shaped groove and a fifth arc-shaped slider. The first mounting member is slidably connected to the first friction member through the fifth sliding structure, and the second mounting member is slidably connected to the second friction member through the fifth sliding structure.

[0049] The rotation of the torsion structure with the adjacent first and second friction components is achieved through the fifth sliding structure, allowing the first and second mounting components to be considered as transition pieces between the first and second friction components. Increasing the relative rotational trajectory of the first and second friction components facilitates miniaturization while ensuring a large opening angle for the electronic device.

[0050] Furthermore, the fifth sliding structure helps to further increase the friction of the first and second rotating components, thereby enhancing the torque of the rotating shaft mechanism.

[0051] In one possible implementation, the torsion structure may further include a first guide rod and a second guide rod, one end of the first guide rod and one end of the second guide rod being respectively inserted into opposite ends of the first mounting member along the rotation direction, and the other ends of the first guide rod and the second guide rod being respectively inserted into opposite ends of the second mounting member along the rotation direction, with the first guide rod and the second guide rod extending along a first direction.

[0052] The first guide rod and the second guide rod can guide and limit the movement of the first mounting component and the second mounting component, ensuring that the first mounting component and the second mounting component move along the first direction under the action of the first elastic element.

[0053] In one possible implementation, among a plurality of fifth adapters, one fifth adapter adjacent to the first mounting member is connected to the first mounting member, and another fifth adapter adjacent to the second mounting member is connected to the second mounting member. This allows the torsion structure to rotate synchronously with the fifth adapters and other adapters, improving the opening and closing effect.

[0054] In one possible implementation, the first mounting component is connected to one of the fifth adapters via a sixth connector, and the second mounting component is connected to another of the fifth adapters via a seventh connector, which facilitates the assembly of the first mounting component, the second mounting component, and the fifth adapter, making installation convenient and quick.

[0055] In one possible implementation, the torsion structure is located outside the outer part, which reduces the size of the outer part while ensuring that the rotating shaft mechanism can provide stable torque, thus improving the aesthetics and overall appearance of the electronic device when it is in the open state.

[0056] The rotating shaft mechanism also includes a support rod extending along a first direction, one end of which is disposed on a first mounting portion of the first fixing member, and a second mounting portion of the first fixing member is disposed on the support rod. The torque structure includes a second elastic element disposed on the support rod, located on the side of the second mounting portion of the first fixing member facing away from the first mounting portion. The elastic restoring force of the second elastic element can act on the second mounting portion, pushing it towards the first mounting portion, compressing the structural components located between the first and second mating portions, and providing stable torque.

[0057] In one possible implementation, the second mounting part and the second elastic element are movably sleeved on the support rod, so that the second mounting part and the second elastic element can move along the support rod.

[0058] The torsion structure also includes a first adjusting member, which is located on the side of the second elastic member facing away from the second mounting part. The first adjusting member can limit the second elastic member, so that the second elastic member is assembled between the first adjusting member and the second mounting part.

[0059] The first adjusting member can move along the support rod. By adjusting the position of the first adjusting member on the support rod, the position of the second elastic member can be adjusted, thereby adjusting the degree of compression of each structural member by the second elastic member, and realizing the torque adjustment of the rotating shaft mechanism. Under the condition of providing stable torque, different design requirements can be met.

[0060] In one possible implementation, the outer wall of the support rod has external threads, and the inner wall of the first adjusting member has internal threads that mate with the external threads. Applying an external force to rotate the first adjusting member allows it to rotate relative to the support rod while simultaneously sliding along the support rod, thus adjusting the position of the first adjusting member on the support rod and achieving torque adjustment of the rotating shaft mechanism.

[0061] Without external force, the threaded engagement of the internal and external threads prevents the first adjusting member from sliding relative to the support rod, thus fixing the position of the first adjusting member on the support rod and achieving the limiting and fixing of the first adjusting member, enabling the rotating shaft mechanism to provide smooth torque.

[0062] The second mounting part, the second elastic element, and the support rod are connected by a movable assembly. Under the action of external force, the second elastic element can undergo elastic expansion and contraction deformation, which acts on the second mounting part, allowing the second mounting part to move along the support rod. This ensures that under the action of the second elastic element, it can push the second mounting part and the second mating part connected to the second mounting part, thereby compressing the structural components of the first rotating assembly and the second rotating assembly.

[0063] In one possible implementation, the first mounting part includes a first section and a first extension section. A first mating part and a support rod are connected to the first section. One end of the first extension section is connected to the first section. The other end of the first extension section extends along a first direction and at least partially overlaps with the second mounting part. A first through hole is provided on the first extension section, and a first fixing hole is provided on the second mounting part.

[0064] The rotating shaft mechanism also includes a first assembly, one end of which abuts against the first extension, and the other end of which passes through the first through hole and is detachably assembled with the first fixing hole.

[0065] The inner diameter of the first through hole along the first direction is larger than the outer diameter of the first assembly along the first direction. The position of the first assembly within the first through hole is adjustable along the first direction. This ensures that during assembly or torque adjustment, the second mounting part and the first mounting part can move relative to each other along the first direction to press against each structural component. After assembly and torque adjustment are completed, stable assembly of the second mounting part and the first mounting part can be achieved through the first assembly, maintaining torque on the rotating shaft mechanism and providing smooth torque.

[0066] During assembly or torque adjustment, the first assembly can be removed, allowing the first mounting part and the second mounting part to move relative to each other in a first direction, thereby pressing the structural components to achieve the required torque. After assembly or torque adjustment, one end of the first assembly passes through the first through hole, and the other end of the first assembly is assembled with the first fixing hole, achieving stable assembly of the first mounting part and the second mounting part, so that the rotating shaft mechanism can maintain a smooth torque.

[0067] In one possible implementation, the second mounting portion includes a second sub-part and a second extension portion, a third mating portion is connected to the second sub-part, one end of the second extension portion is connected to the second sub-part, the other end of the second extension portion extends along a first direction and at least partially overlaps with the fourth mounting portion, a second through hole is provided on the second extension portion, and a second fixing hole is provided on the fourth mounting portion.

[0068] The rotating shaft mechanism also includes a second assembly, one end of which abuts against the second extension, and the other end of which passes through the second through hole and is detachably assembled with the second fixing hole.

[0069] The inner diameter of the second through hole along the first direction is larger than the outer diameter of the second assembly along the first direction, allowing the position of the second adjusting piece within the second through hole to be adjusted. This ensures that the fourth mounting part can move relative to the third mounting part during assembly or torque adjustment to press against each structural component. After assembly or torque adjustment, the third and fourth mounting parts are stably assembled together, enabling the rotating shaft mechanism to provide smooth torque.

[0070] During assembly or torque adjustment, the second mounting part can be removed, and the third and fourth mounting parts can move relative to each other in the first direction to press the structural components together. After assembly or torque adjustment, one end of the second mounting part passes through the second through hole, and the other end of the second mounting part is assembled with the second fixing hole to achieve stable assembly of the third and fourth mounting parts.

[0071] In one possible implementation, the first fixing member includes a first outer surface and a first inner surface opposite to each other, and the second fixing member includes a second inner surface located on the same side of the rotating mechanism as the first inner surface. The flexible circuit board portion of the electronic device can be fixed to the first outer surface, and a portion of the flexible circuit board can be laid on the first and second inner surfaces. When the rotating mechanism switches from a closed state to an open state, the bent portion of the flexible circuit board unfolds as the rotating mechanism opens. The length of the flexible circuit board located in the rotation area of ​​the rotating mechanism decreases, resulting in redundancy of the flexible circuit board at other locations outside the rotation area of ​​the rotating mechanism.

[0072] The rotating shaft mechanism also includes a sliding block, part of which is located on the side of the first fixing member away from the second fixing member. A portion of the flexible circuit board can be laid on the sliding block, which is slidably connected to the first fixing member. When the rotating shaft mechanism switches from a closed state to an open state, the sliding block slides away from the first fixing member. Increasing the distance between the sliding block and the first fixing member increases the length of the flexible circuit board that the first fixing member and the sliding block can support, thus absorbing the redundancy of the flexible circuit board.

[0073] In one possible implementation, the rotating shaft mechanism further includes a fixed block and a third elastic element. The fixed block is disposed on the first outer surface, and a portion of the flexible circuit board can be fixed to the fixed block. The sliding block is slidably connected to the fixed block. The fixed block enables the sliding assembly of the sliding block and the first fixed element.

[0074] The third elastic element is positioned between the fixed block and the sliding block. When the rotating shaft mechanism is in the closed state, part of the flexible circuit board bends, and the flexible circuit board can pull the sliding block. The distance between the sliding block and the fixed block is small, causing the third elastic element to be compressed. When the rotating shaft mechanism switches from the closed state to the open state, part of the flexible circuit board unfolds. Under the elastic recovery action of the third elastic element, the sliding block can move away from the first fixed element along the width direction, achieving the effect of absorbing redundancy.

[0075] In one possible implementation, the fixed block is provided with a guide groove, the extension direction of which is perpendicular to the first direction, and the sliding block is provided with a sliding member that slides along the guide groove. The guide groove serves as a guide and limiter, ensuring that the sliding block slides only in the width direction toward or away from the fixed block (first fixed member).

[0076] In one possible implementation, the fixing block includes a base plate, a first fixing body, and a second fixing body. The first and second fixing bodies are disposed on one side of the base plate, and there is a receiving gap between them. A third elastic element is disposed within this receiving gap, and the first and second fixing bodies have guide grooves. This arrangement of the fixing block, sliding block, and third elastic element is compact, facilitating the miniaturization of the rotating shaft mechanism.

[0077] In one possible implementation, the first mounting portion is disposed on both sides of the first mating portion along the first direction, and the second mounting portion is disposed on both sides of the second mating portion along the first direction. The first mounting portion and the first mating portion can be an integral structural component, and their dimensions in the first direction can be relatively small; for example, the integral structural component formed by the first mounting portion and the first mating portion can be a strip-like structure.

[0078] The torque structure includes a second adjusting member and a third adjusting member. The two ends of the first mounting part and the two ends of the second mounting part are connected by the second adjusting member and the third adjusting member, respectively. When the two ends of the first mounting part and the second mounting part are connected by the second adjusting member and the third adjusting member, the second adjusting member and the third adjusting member can push the first mounting part towards the second mounting part, causing a certain deformation of the first mating part connected to the first mounting part. This can press the first mating part, the second mating part, and the third mating part, the fourth mating part, the first friction member, and the second friction member located between the first and second mating parts, ensuring that the rotating shaft mechanism can provide stable torque. The dimensions and structural design of the first fixing member, the second fixing member, and the torque structure are simpler, which is more conducive to simplifying the structure of the rotating shaft mechanism and realizing the miniaturization of the rotating shaft mechanism.

[0079] In one possible implementation, the second and third adjusting members are movable relative to the first and second mounting portions. This movement adjusts the gap between the first and second mounting portions, such as decreasing or increasing the gap width, resulting in different deformations of the first mating portion. This adjustment of the deformation of the first mating portion allows for control over the degree of compression between the structural components of the first and second mating portions, thereby regulating the torque of the rotating shaft mechanism. Providing stable torque also meets various design requirements.

[0080] In one possible implementation, the first mating part has a first protruding structure on the side facing the third mating part, and the end face of the first protruding structure facing away from the first mating part has a first protruding surface. The third mating part has a second protruding structure on the side facing the first mating part, and the end face of the second protruding structure facing away from the third mating part has a second protruding surface.

[0081] When the rotating shaft mechanism switches from the first intermediate state to the open state, the first protruding surface of the first protruding structure and the second protruding surface of the second protruding structure come into contact. In the first direction, the third mating part pushes the first friction element, the second friction element, the fourth mating part, and the second mating part, thereby increasing the rotational friction between the structural components, providing greater torque, and ensuring the hovering effect.

[0082] By incorporating the raised structure, the pivot mechanism can generate varying torque during opening and closing, meeting different hovering requirements in various states and improving the damping feel during operation. For example, when the pivot mechanism is in the closed state or at a small angle, the torque can be relatively small; when the pivot mechanism is in a larger angle (such as the first intermediate state) or in the open state, the torque can be relatively large, achieving better hovering performance and meeting usage needs.

[0083] A second aspect of this application provides an electronic device, including a display terminal, a keyboard terminal, and any of the above-described rotating mechanisms. The keyboard terminal includes a first housing, the display terminal includes a second housing, a first rotating component of the rotating mechanism is connected to the first housing, and a second rotating component of the rotating mechanism is connected to the second housing.

[0084] In one possible implementation, the first housing includes a main body and an edge portion. The edge portion is located on one side of the main body and protrudes from the main body, forming a stepped structure with the main body. The edge portion has an internal assembly cavity, where at least a portion of the first rotating component is located. A clearance hole for the second rotating component to pass through is formed on the side surface of the edge portion. The virtual axis of the rotating shaft mechanism can be located at the joint between the edge portion of the second housing and the first housing, resulting in a smaller joint between the two housings. This allows the second housing to fit more closely to the first housing, and the width of the joint does not change significantly during rotation. Furthermore, the radius of rotation of the second housing relative to the first housing is smaller, and the second housing does not rise significantly in the thickness direction relative to the first housing during opening and closing of the electronic device. This reduces the sense of separation between the first and second housings, improving the aesthetics and overall integrity of the electronic device.

[0085] A third aspect of this application provides an electronic device, including a device body, a bracket, and any of the aforementioned rotating shaft mechanisms. The device body includes a first housing, the bracket includes a second housing, a first rotating component of the rotating shaft mechanism is connected to the first housing, and a second rotating component of the rotating shaft mechanism is connected to the second housing.

[0172] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0173] This application provides an electronic device that needs to be opened and closed, such as a mobile phone, a personal digital assistant (PDA), a laptop computer, a tablet computer with a stand, a handheld game console, etc.

[0174] The electronic device may include a first housing, a rotating shaft mechanism, and a second housing. The first housing and the second housing may be connected to the rotating shaft mechanism respectively, so that the first housing and the second housing can be rotated together through the rotating shaft mechanism. The second housing is rotatable relative to the first housing, thereby realizing the opening and closing of the electronic device.

[0175] Figure 1 This is a schematic diagram of an electronic device in an open state, provided as an embodiment of this application.

[0176] For example, see in some examples Figure 1 As shown, taking a laptop computer as an example, the electronic device 100 may include a first housing 101 and a second housing 102, and the first housing 101 may be located on one side of the second housing 102.

[0177] For example, an electronic device 100 may include a display terminal and a keyboard terminal. The keyboard terminal may include a first housing 101 and a key structure (not shown in the figure). The first housing 101 can serve as the main load-bearing structure of the keyboard terminal, and the key structure can be assembled into the first housing 101. For example, the key structure can be located on the side of the first housing 101 facing the second housing 102. The key structure can be used to recognize user operation information and can also realize human-computer interaction with the user. It should be understood that the key structure can be a protruding mechanical button structure, or it can be a virtual button, etc.

[0178] The display end may include a second housing 102 and a display screen 104. The second housing 102 may serve as the main load-bearing structural component of the display end, and the display screen 104 may be assembled on the second housing 102. For example, the display screen 104 may be located on one side of the second housing 102.

[0179] The side of the display screen 104 facing away from the second housing 102 can be the display surface. The display screen 104 can be used to display images, etc., and can also be used to recognize user operation information, such as user operation position information, gesture information, etc., to realize human-computer interaction with the user.

[0180] In this embodiment, the type of display screen 104 is not limited. For example, display screen 104 can be an organic light-emitting diode (OLED) display screen. Of course, in some examples, display screen 104 can also be a micro organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a light-emitting diode (LED) display screen, a mini organic light-emitting diode (Mini LED) display screen, a micro organic light-emitting diode (Micro LED) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD), etc.

[0181] It should be noted that the keyboard and display terminals may also include other functional modules to ensure the completeness of the electronic device 100's functions. For example, the keyboard terminal may also include functional modules such as the main control circuit board, charging and discharging system, heat sink, microphone, and speaker, while the display terminal may also include functional modules such as a camera module.

[0182] In the embodiments of this application, see Figure 1As shown, the thickness direction of the first housing 101 is taken as the thickness direction of the electronic device 100, as indicated by the z-direction in the figure; the width direction of the first housing 101 is taken as the width direction of the electronic device 100, as indicated by the x-direction in the figure; and the length direction of the first housing 101 is taken as the length direction of the electronic device 100, as indicated by the y-direction in the figure. The length, width, and thickness in this embodiment are for descriptive convenience only and do not imply any limitation on the dimensions. For example, the length can be greater than, equal to, or less than the width.

[0183] The electronic device 100 may further include a rotating shaft mechanism 103. The first housing 101 and the second housing 102 may be located on both sides of the rotating shaft mechanism 103. The rotating shaft mechanism 103 is connected to the first housing 101 and the second housing 102 respectively, and the first housing 101 and the second housing 102 can be rotated together through the rotating shaft mechanism 103. The axis of relative rotation of the first housing 101 and the second housing 102 may be parallel to the length direction of the electronic device 100, that is, the first housing 101 and the second housing 102 can rotate relative to each other about the length direction (y direction). The display end and the system end of the electronic device 100 can rotate relative to each other, realizing the opening and closing of the electronic device 100.

[0184] The pivot mechanism 103 is also used to provide torque (or damping force) so that the electronic device 100 can be held in a certain state when no external force is applied. For example, the electronic device 100 can be held in an open state, a closed state, or any intermediate state between the two, to meet the hovering requirements of the electronic device 100.

[0185] See Figure 1 As shown, the first housing 101 and the second housing 102 can be unfolded relative to each other to the open state. The first housing 101 and the second housing 102 are unfolded relative to each other until they can no longer rotate. At this time, the electronic device 100 is in the open state, which can also be called the unfolded state.

[0186] Figure 2 for Figure 1 A side view of the structure of an electronic device.

[0187] For example, when the electronic device 100 is in the open state, the second housing 102 can open at a certain angle relative to the first housing 101. Taking the angle between the first housing 101 and the second housing 102 as angle α in the figure as an example, the angle α between the first housing 101 and the second housing 102 can be approximately 135°.

[0188] It should be noted that when the electronic device 100 is in the open state, the angle between the first housing 101 and the second housing 102 can be selected and set according to actual design requirements. For example, when the electronic device 100 is in the open state, the angle α between the first housing 101 and the second housing 102 can be 120°, 140°, 150°, 160°, 170°, 180°, etc.

[0189] It should be noted that slight deviations are allowed in the perspectives illustrated in the embodiments of this application. For example, taking... Figure 2 Taking the electronic device 100 shown as an example when it is in the open state, the angle α between the first housing 101 and the second housing 102 can be 135°, or approximately 135°, such as 130°, 133°, 136° or 137°.

[0190] Figure 3 for Figure 1 A schematic diagram of the structure of an electronic device in an intermediate state.

[0191] See Figure 3 As shown, the first housing 101 and the second housing 102 can rotate relative to each other (fold or open) to an intermediate state so that the electronic device 100 is in an intermediate state. For example, when the electronic device 100 is in the open state, the angle α between the first housing 101 and the second housing 102 is approximately 135°. When the electronic device 100 is in the intermediate state, the range of the included angle α between the first housing 101 and the second housing 102 can be 0 < α < 135°.

[0192] Figure 4 for Figure 1 A schematic diagram of the structure of an electronic device in a closed state.

[0193] See Figure 4 As shown, the first housing 101 and the second housing 102 can be folded relative to each other into a closed state. When the first housing 101 and the second housing 102 are in the closed state, they can be completely closed together and parallel to each other (a slight deviation is allowed). The included angle between the first housing 101 and the second housing 102 can be approximately 0°. At this time, the electronic device 100 is in a closed state, also known as a folded state. The electronic device 100 can be folded into a two-layer form, and there can be a narrow gap between the first housing 101 and the second housing 102.

[0194] It is understandable that the intermediate state can be any state between the open state and the closed state. That is to say, the electronic device 100 can switch between the open state and the closed state through the movement of the rotating shaft mechanism 103, and the electronic device 100 can have multiple intermediate states.

[0195] For example, the first housing 101 may include a main body portion 1010 and an edge portion 1011. The edge portion 1011 may be located on one side of the main body portion 1010, for example, along the width direction (x direction), the edge portion 1011 may be located at the edge position of one side of the main body portion 1010.

[0196] The edge portion 1011 may protrude from the main body portion 1010. For example, in the thickness direction (z direction), the height of the edge portion 1011 is higher than the height of the main body portion 1010, so that the edge portion 1011 and the main body portion 1010 can form a stepped structure.

[0197] In this embodiment of the application, the shape of the step structure formed by the main body 1010 and the edge 1011 is not limited. The shape of the step structure can be a strip, a zigzag, etc.

[0198] Figure 5 This is a schematic diagram of the structure of another electronic device in an intermediate state, as provided in an embodiment of this application.

[0199] Alternatively, in some examples, electronic device 100 can be an electronic device with a stand, such as a tablet computer with a stand, see [reference needed]. Figure 5 As shown, the electronic device 100 may include a bracket 100b and a device body 100a. The device body 100a may include a first housing 101 and a display screen 104. The type and function of the display screen 104 can be referred to the display screen above, and will not be repeated here.

[0200] In this context, the thickness, width, and length directions of the first housing 101 are still used as the thickness, width, and length directions of the electronic device 100, such as... Figure 5 Only the thickness and width directions are shown, represented by the z and x directions in the figure, respectively. The length direction can be the y direction, and can be perpendicular to both the thickness and width directions. Length, width, and thickness are for descriptive convenience only and do not imply any limitation on the dimensions.

[0201] The bracket 100b may include a second housing 102, and the second housing 102 and the display screen 104 may be located on opposite sides of the first housing 101, such as in the thickness direction (z direction), the second housing 102 and the display screen 104 may be located on opposite sides of the first housing 101.

[0202] A rotating shaft mechanism 103 is provided between the first housing 101 and the second housing 102. The rotating shaft mechanism 103 can be connected to one end of the second housing 102 and the first housing 101 respectively, so that the second housing 102 can rotate relative to the first housing 101, such as rotating about its length relative to the first housing 101. This also allows the bracket 100b to rotate relative to the device body 100a, realizing the opening and closing of the bracket 100b relative to the device body 100a, satisfying the opening and closing requirements of the electronic device 100, which can also be said to realize the opening and closing of the electronic device 100.

[0203] The first housing 101 and the second housing 102 can be unfolded relative to each other to the open state. The first housing 101 and the second housing 102 are unfolded relative to each other until they can no longer rotate. At this time, the bracket 100b and the electronic device 100 are in the open state.

[0204] For example, see Figure 5 As shown, the second housing 102 can open at a certain angle relative to the first housing 101. The angle between the first housing 101 and the second housing 102 is taken as... Figure 5 Taking the angle θ as an example, when the electronic device 100 is in the open state, the angle θ between the first housing 101 and the second housing 102 can be approximately 90° (deviations are allowed).

[0205] It is understandable that when the electronic device 100 is in the open state, the angle between the first housing 101 and the second housing 102 can be selected and set according to actual design requirements. For example, when the electronic device 100 is in the open state, the angle θ between the first housing 101 and the second housing 102 can be 80°, 75°, 70°, 60°, etc.

[0206] The first housing 101 and the second housing 102 can rotate relative to each other to an intermediate state, so that the bracket 100b and the electronic device 100 are in the intermediate state. For example, when the electronic device 100 is in the intermediate state, the angle θ between the first housing 101 and the second housing 102 can be in the range of 0 < θ < 90°. The intermediate state can be any state between the open state and the closed state.

[0207] Figure 6 for Figure 5 A schematic diagram of the structure of an electronic device in a closed state.

[0208] See Figure 6As shown, the first housing 101 and the second housing 102 can be folded relative to each other to a closed state. The first housing 101 and the second housing 102 can be closed to be parallel to each other (deviation is allowed). The included angle between the first housing 101 and the second housing 102 can be approximately 0°. At this time, the bracket 100b and the electronic device 100 are in a closed state. There can be a small gap between the first housing 101 and the second housing 102.

[0209] For example, a receiving groove (not shown in the figure) may be formed on the side of the first housing 101 facing away from the display screen 104. When the electronic device 100 is in a closed state, the second housing 102 can be placed in the receiving groove, so that the side of the first housing 101 facing away from the display screen 104 and the side of the second housing 102 facing away from the display screen 104 are flush. This helps to improve the appearance and flatness of the electronic device 100.

[0210] Figure 7 This is a schematic diagram of the structure of an electronic device in the open state in the related art.

[0211] Currently, most foldable electronic devices, such as laptops, use a physical hinge mechanism for their hinges. For example, see [link to example]. Figure 7 As shown, the first housing 201 may have a stepped structure 201a on one side, and a rotating shaft mechanism (not shown in the figure) is disposed inside the stepped structure 201a. The second housing 202 has a connector 203 on one side. The second housing 202 can be rotatably engaged with the rotating shaft mechanism through the connector 203, so that the second housing 202 can rotate around the rotating shaft mechanism, thereby realizing the rotational engagement between the first housing 201 and the second housing 202.

[0212] The rotating shaft mechanism may include a columnar rotating shaft, a solid structural component with a certain diameter. The centerline of the rotating shaft is usually the axis of rotation of the second housing, meaning the axis of rotation is located on the solid structure within the rotating shaft mechanism. The large distance between the centerline of the second housing 202 and the rotating shaft results in a large radius of rotation for the second housing 202 relative to the first housing 201. During rotation, the second housing 202 is raised relative to the first housing 201 in the thickness direction. When the electronic device 200 is in the open state, a large distance A exists between the first housing 201 and the second housing 202, resulting in a strong sense of separation between them and a poor overall appearance and aesthetics of the electronic device 200.

[0213] In electronic devices such as tablets with stands, to meet the simplified structural design requirements of tablets, the hinge mechanism often adopts a virtual hinge solution. That is, the hinge mechanism does not have a physical shaft or hole structure, and the axis of rotation of the stand relative to the electronic device is not located inside the hinge mechanism, but can be located outside the hinge mechanism, which is a virtual axis. However, hinge mechanisms using virtual axes often have difficulty providing stable torque, affecting the opening, closing and hovering effects, and reducing the opening and closing experience.

[0214] Based on this, this application provides a rotating shaft mechanism. The first rotating component of the rotating shaft mechanism includes multiple first friction elements, and the second rotating component includes multiple second friction elements. The multiple first friction elements and multiple second friction elements are staggered along a first direction. Adjacent first and second friction elements have a first sliding structure. The first sliding structure includes a slidingly fitted first arc-shaped slider and a first arc-shaped groove, allowing the multiple first and second friction elements to be rotatably connected through the first sliding structure, thereby achieving relative rotation between the first and second rotating components. The rotation axis of the second rotating component relative to the first rotating component is a straight line passing through the center of the first arc-shaped groove and parallel to the first direction. The rotating shaft mechanism does not have a physical rotating shaft, shaft hole, or other structures. The rotation axis is located outside the physical structure of the rotating shaft mechanism, meaning that the first and second rotating components rotate relative to each other around a virtual axis, reducing the space occupied by the rotating shaft mechanism. The placement of the rotating shaft mechanism in the electronic device is also more flexible. For example, the virtual axis of the rotating shaft mechanism can be located at the joint between the first and second housings of the electronic device, making the joint between the first and second housings smaller, and allowing the second housing to be closer to the first housing. The design minimizes the change in seam width during the opening and closing of the electronic device, and the second housing does not significantly rise relative to the first housing in the thickness direction. When the electronic device is in the open state, the separation between the first and second housings is minimal, enhancing the device's aesthetics and overall integrity. The torque structure of the rotating shaft mechanism presses against the first and second rotating components in the first direction, increasing the friction between the first and second friction elements. This provides stable torque for the rotation of the first and second rotating components, meeting the torque requirements during the opening and closing process of the electronic device and ensuring its opening, closing, and hovering effects.

[0215] This hinge mechanism can be used in electronic devices such as laptops to allow rotation between the display and keyboard. It can also be used in electronic devices with rotatable stands, such as tablets with stands, to allow rotation between the stand and the main body of the device.

[0216] Figure 8 for Figure 1 Enlarged schematic diagram of a local structure in section A.

[0217] For example, see Figure 8As shown, taking the hinge mechanism 103 assembled in the above-mentioned laptop as an example, at least a portion of the hinge mechanism 103 can be assembled to the edge portion 1011 of the first housing 101, and one side of the second housing 102 can be connected to the hinge mechanism 103.

[0218] Figure 9 for Figure 8 A schematic diagram of the partial disassembly structure of an electronic device.

[0219] See Figure 9 As shown, taking the elongated shape of the stepped structure formed by the main body 1010 and the edge 1011 as an example, the main body 1010 may include a first surface 1010a, and the button structure may be located on the side of the first surface 1010a.

[0220] The edge portion 1011 may include a second surface 1011a and a side surface 1011b. The first surface 1010a and the second surface 1011a may be located on opposite sides of the side surface 1011b, respectively. The first surface 1010a may intersect with the side surface 1011b, and the second surface 1011a may also intersect with the side surface 1011b. For example, the first surface 1010a and the second surface 1011a may be perpendicular to the side surface 1011b, or the first surface 1010a may be parallel to the second surface 1011a. The first surface 1010a, the side surface 1011b, and the second surface 1011a may be sequentially connected to form a stepped structure.

[0221] An assembly cavity (not shown) may be provided inside the edge portion 1011, in which at least a portion of the rotating shaft mechanism 103 may be accommodated. A clearance hole 1012 may be provided on the side surface 1011b of the edge portion 1011, which is used to clear the rotating shaft mechanism 103. A portion of the rotating shaft mechanism 103 may pass through the clearance hole 1012 and be connected to the second housing 102.

[0222] A clearance hole (not shown in the figure) for the rotating shaft mechanism 103 to pass through can also be provided on one side of the second housing 102. The part of the rotating shaft mechanism 103 connected to the second housing 102 can pass through the clearance hole and be accommodated in the second housing 102.

[0223] When the electronic device 100 is in the closed state, the second housing 102 may be located on the side of the edge portion 1011 facing the main body portion 1010 (see reference). Figure 4 (As shown). The rotating mechanism 103 can be accommodated in the second housing 102 and the edge portion 1011 of the first housing 101 respectively. The joint between the second housing 102 and the edge portion 1011 is in a straight line. The side of the second housing 102 facing away from the first housing 101 can be flush with the edge portion 1011, making the overall appearance of the electronic device 100 simple and beautiful.

[0224] When electronic device 100 is in the open state (refer to...) Figure 8 As shown, although the part of the rotating mechanism 103 is exposed, it does not appear abrupt. The distance between the first housing 101 and the first housing 101 is relatively close, which reduces or avoids the sense of separation and makes the overall appearance and aesthetics of the electronic device 100 better.

[0225] For example, consider the hinge mechanism 103 assembled in the aforementioned tablet computer with a stand 100b (see [reference]). Figure 6 As shown), at least a portion of the pivot mechanism 103 can be mounted on the side of the first housing 101 facing away from the display screen 104. For example, a portion of the pivot mechanism 103 can be located on the bottom wall of the receiving groove on the first housing 101, and a portion can extend into the interior of the first housing 101 through the side wall of the receiving groove. One side of the second housing 102 can be connected to the pivot mechanism 103.

[0226] The pivot mechanism 103 is located between the side of the first housing 101 facing away from the display screen 104 and the second housing 102. When the electronic device 100 is in any state, such as open, closed, or intermediate, the pivot mechanism 103 is not easily observed.

[0227] The structure of the rotating shaft mechanism 103 is illustrated below with reference to the accompanying drawings.

[0228] Figure 10 This is a schematic diagram of a rotating shaft mechanism provided in an embodiment of this application. Figure 10 The diagram shows a schematic of a rotating shaft mechanism provided in this application when it is in a flattened state.

[0229] See Figure 10 As shown, the rotating shaft mechanism 103 may include a first rotating component 10, which may be assembled with one of the first housing and the second housing of the electronic device. Exemplarily, in this embodiment, the assembly of the first rotating component 10 with the first housing is used as an example for illustration.

[0230] For example, the first rotating assembly 10 may include a first fixing member 11, which can be connected to the first housing so that the first rotating assembly 10 and the first housing are assembled together. The connection method between the first fixing member 11 and the first housing is not limited. For example, the first fixing member 11 can be connected to the first housing by means of threaded connection, riveting, bonding, snap-fit ​​connection, etc.

[0231] The rotating shaft mechanism 103 also includes a second rotating component 20, which is assembled with another of the first housing and the second housing. For example, the second rotating component 20 is assembled with the second housing.

[0232] For example, the second rotating assembly 20 may include a second fixing member 21, which can be connected to the second housing, so that the second rotating assembly 20 and the second housing are assembled together. The connection method between the second fixing member 21 and the second housing is not limited. For example, the second fixing member 21 can be connected to the second housing by means of threaded connection, riveting, bonding, snap-fit ​​connection, etc.

[0233] The first rotating assembly 10 and the second rotating assembly 20 can be rotated together. The second rotating assembly 20 can rotate relative to the first rotating assembly 10, thereby causing the second housing to rotate relative to the first housing, realizing the opening and closing of the electronic device. The rotation axis of the first rotating assembly 10 and the second rotating assembly 20 that rotate relative to each other can be parallel to the length direction of the electronic device.

[0234] The first rotating assembly 10 may also include a plurality of first friction elements 12, and the second rotating assembly 20 may also include a plurality of second friction elements 22. The plurality of first friction elements 12 and the plurality of second friction elements 22 may be staggered along a first direction. The first direction may be approximately parallel to the rotation axis of the first rotating assembly 10 and the second rotating assembly 20 that rotate relative to each other (a certain error is allowed), as shown in the y direction in the figure.

[0235] The first friction element 12 and the second friction element 22 can be staggered along the first direction (y direction), see [reference]. Figure 10 As shown, taking the first rotating assembly 10, which includes four first friction elements 12 (e.g., first friction element 12a, first friction element 12b, first friction element 12c, and first friction element 12d), and the second rotating assembly 20, which includes three second friction elements 22 (e.g., second friction element 22a, second friction element 22b, and second friction element 22c), as an example, the first friction elements 12a, 12b, 12c, and 12d are distributed sequentially in the first direction (y-direction).

[0236] Adjacent first friction element 12 and second friction element 22 have a first sliding structure. For example, taking adjacent first friction element 12a and second friction element 22a as an example, the first friction element 12a and second friction element 22a may have a first sliding structure 31. Figure 10 The diagram shows two first sliding structures 31 between the first friction member 12a and the second friction member 22a.

[0237] Figure 10a for Figure 10 A schematic diagram of the disassembled structure of the first and second friction components from a single perspective. Figure 10b for Figure 10A schematic diagram of the disassembled structure of the first and second friction components from another perspective. Figure 10a This is a schematic diagram of the split structure from a viewpoint along the direction from the first friction member 12a toward the second friction member 22a. Figure 10b This is a schematic diagram of the split structure from the perspective of the direction along the second friction member 22a toward the first friction member 12a.

[0238] The first sliding structure includes a first arc-shaped groove and a first arc-shaped slider that slide together. For example, see [link to relevant documentation]. Figure 10a As shown, taking the first friction member 12a and the second friction member 22a as an example, there can be a sliding adapter 70 between the first friction member 12a and the second friction member 22a, so that there is a first sliding structure 31b between the first friction member 12a and the sliding adapter 70, and there is a first sliding structure 31a between the second friction member 22a and the sliding adapter 70.

[0239] Combination Figure 10a and Figure 10b As shown, the first sliding structure 31a may include a first arc-shaped groove 221 and a first arc-shaped slider 72. For example, the sliding adapter 70 may have a raised first arc-shaped slider 72 on the side facing the second friction member 22a, and the second friction member 22a may have a first arc-shaped groove 221 on the side facing the sliding adapter 70. The first sliding structure 31b may include a first arc-shaped groove 122 and a first arc-shaped slider 71. For example, the first friction member 12a may have a first arc-shaped groove 122 on the side facing the sliding adapter 70, and the sliding adapter 70 may have a raised first arc-shaped slider 71 on the side facing the first friction member 12a. The shapes of the first arc-shaped groove 221, the first arc-shaped groove 122, the first arc-shaped slider 72, and the first arc-shaped slider 71 can all be circular arcs, elliptical arcs, etc.

[0240] The first arc-shaped slider 72 can slide along the first arc-shaped slide groove 221, and the first arc-shaped slider 71 can slide along the first arc-shaped slide groove 122, so that the first friction member 12a and the second friction member 22a can be slidably connected through the first sliding structure 31a and the first sliding structure 31b, so that the multiple first friction members 12 and the multiple second friction members 22 can rotate relative to each other, thereby enabling the first rotating assembly 10 and the second rotating assembly 20 to achieve rotational engagement.

[0241] It should be noted that in some other examples, there may only be one first sliding structure between the first friction member and the second friction member. For example, taking the first friction member 12a and the second friction member 22a as an example, the sliding transition member 70 may not be provided between the first friction member 12a and the second friction member 22a. On one of the opposite sides of the first friction member 12a and the second friction member 22a, there may be a first arc-shaped groove on one side and a raised first arc-shaped slider on the other side. The first arc-shaped groove and the first arc-shaped slider constitute a first sliding structure. The first arc-shaped slider can be inserted into the first arc-shaped groove and slide along the first arc-shaped groove, or the first friction member and the second friction member can achieve rotational engagement through the first sliding structure.

[0242] It is understandable that the first friction component and the second friction component achieve rotational engagement through the first sliding structure. The first arc-shaped slider of the first sliding structure is inserted into the first arc-shaped groove. There will be a certain assembly gap between the first arc-shaped slider and the first arc-shaped groove, that is, there is a certain assembly gap between the first friction component and the second friction component to meet the relative sliding requirements of the two.

[0243] The second rotating assembly 20 can rotate relative to the first rotating assembly 10. When the second rotating assembly 20 rotates relative to the first rotating assembly 10, the first friction element 12 and the second friction element 22 rotate relative to each other, and the first arc-shaped slider slides along the first arc-shaped groove. The axis of relative rotation of the first rotating assembly 10 and the second rotating assembly 20 is the axis of rotation of the first arc-shaped slider relative to the first arc-shaped groove, that is, the axis of rotation can be a straight line passing through the center of the first arc-shaped groove 221 and parallel to the first direction (y direction), such as... Figure 10 The dashed line L in the middle.

[0244] The rotation axis is not located on the physical structure of the rotating shaft mechanism 103, but outside the physical structure of the rotating shaft mechanism 103. That is, the rotation axis is a virtual axis. The first rotating component 10 and the second rotating component 20 rotate relative to each other around the virtual axis. There are no physical rotating shafts, shaft holes or other structures in the rotating shaft mechanism 103, which reduces the space occupied by the rotating shaft mechanism 103.

[0245] The rotating shaft mechanism 103 also includes a torsion structure 40 (see reference). Figure 10As shown, the torsion structure 40 can apply a force along a first direction (y-direction) to the first rotating assembly 10 and the second rotating assembly 20, thereby squeezing the first rotating assembly 10 and the second rotating assembly 20, that is, squeezing at least the first friction member 12 and the second friction member 22, increasing the friction between the first friction member 12 and the second friction member 22. When the first rotating assembly 10 and the second rotating assembly 20 rotate relative to each other, the friction between the first friction member 12 and the second friction member 22 can serve as rotational torque, providing stable torque for the rotation of the first rotating assembly 10 and the second rotating assembly 20, meeting the torque requirements during the opening and closing process of the electronic device, ensuring the opening, closing and hovering effect of the electronic device, and improving the opening and closing experience.

[0246] It is understandable that by adjusting the force applied by the torque structure 40 to the first rotating component 10 and the second rotating component 20, the torque of the rotating shaft mechanism 103 can be adjusted to ensure the torque required for the opening and closing of the electronic device and to meet the different torque design requirements of the electronic device.

[0247] Figure 11 for Figure 10 A side view of the electronic device in the closed state. Figure 12 for Figure 10 A side view of an electronic device when it is turned on.

[0248] For example, taking a hinge mechanism assembled in an electronic device such as a laptop computer, the first fixing member in the first rotating assembly can be assembled with the first housing 101. For example, at least a portion of the first fixing member can be located in an assembly cavity within the edge portion 1011 of the first housing 101. At least a portion of the second fixing member in the second rotating assembly can extend through a clearance hole on the edge portion 1011 to the outside of the assembly cavity and be assembled with the second housing 102.

[0249] The rotating mechanism occupies little space and has no physical rotating shaft or shaft hole structure. Its placement in electronic devices is also quite flexible, with minimal constraints on the layout of the rotating axis between the rotating mechanism and the electronic device housing. For example, when the rotating mechanism is assembled in an electronic device, its virtual axis can be located at the joint between the first housing 101 and the second housing 102, such as at the joint between the edge 1011 of the second housing 102 and the first housing 101. Figure 11 and Figure 12 As shown, the vertical projection of the virtual axis along the first direction (y direction) is point O in the figure. Point O is located at the joint between the second shell 102 and the edge portion 1011.

[0250] Compared to a physical hinge design, the second housing 102 can be closer to the first housing 101, resulting in a smaller seam between them. The width of the seam remains relatively constant during rotation (i.e., during the opening and closing of the electronic device 100). Furthermore, the virtual axis can be closer to the edge of the second housing 102 adjacent to the first housing 101, leading to a smaller radius of rotation for the second housing 102 relative to the first housing 101. This results in less noticeable lifting of the second housing 102 relative to the first housing 101 in the thickness direction during the opening and closing of the electronic device 100. (See also...) Figure 12 As shown, when the electronic device 100 is in the open state, the distance h between the first housing 101 and the second housing 102 is small, the separation between the first housing 101 and the second housing 102 is small, which improves the aesthetics and overall appearance of the electronic device 100.

[0251] The first and second rotating components of the rotating shaft mechanism rotate around a virtual axis, thereby causing the first and second housings to rotate around the virtual axis, thus realizing the opening and closing of the electronic device.

[0252] The first and second rotating components can be relatively unfolded into an open state, thus placing the rotating shaft mechanism in the open state. For example... Figure 10 As shown, when the rotating shaft mechanism 103 is in the open state, the first rotating component 10 and the second rotating component 20 can be relatively flattened and cannot continue to rotate. The first rotating component 10 and the second rotating component 20 can be approximately 180° apart.

[0253] When the second rotating assembly 20 is assembled with the second housing and the first rotating assembly 10 is assembled with the first housing, the included angle between the second housing and the edge portion can be approximately 180°, and the included angle between the main body portion of the second housing and the first housing is approximately 0°. When the second housing and the main body portion are closed together and parallel to each other, the electronic device is in a closed state.

[0254] Figure 13 for Figure 10 A schematic diagram of the central rotating shaft mechanism in its intermediate state.

[0255] See Figure 13 As shown, the first rotating component 10 and the second rotating component 20 can rotate relative to each other to an intermediate state, so that the rotating shaft mechanism 103 is in an intermediate state. It is understood that when the rotating shaft mechanism 103 is in the intermediate state, the included angle between the first rotating component 10 and the second rotating component 20 is smaller than the included angle between the first rotating component 10 and the second rotating component 20 when the rotating shaft mechanism 103 is in the open state. For example, when the rotating shaft mechanism 103 is in the intermediate state, the included angle between the first rotating component 10 and the second rotating component 20 can be greater than 35° and less than 180°. At this time, the electronic device is also in an intermediate state.

[0256] Figure 14 for Figure 10 A schematic diagram of the central pivot mechanism in the closed state.

[0257] See Figure 14 As shown, the first rotating component 10 and the second rotating component 20 can be folded relative to each other to a closed state, so that the rotating shaft mechanism 103 is in a closed state. When the rotating shaft mechanism 103 is in the closed state, the included angle between the first rotating component 10 and the second rotating component 20 is smaller than the included angle between the first rotating component 10 and the second rotating component 20 when the rotating shaft mechanism 103 is in the intermediate state. For example, when the rotating shaft mechanism 103 is in the closed state, the included angle between the first rotating component 10 and the second rotating component 20 can be approximately 35°.

[0258] The angle between the edge of the second housing and the first housing can be approximately 35°, and the angle between the main body of the second housing and the first housing can be approximately 135°. At this time, the electronic device is in the open state.

[0259] It is understandable that the intermediate state of the rotating shaft mechanism 103 can be any state between the open state and the closed state of the rotating shaft mechanism 103.

[0260] It should be noted that the arrangement of the first fixing member 11, the second fixing member 21, the first friction member 12, and the second friction member 22 can be varied. For example, a friction member group can be formed by staggered first friction members 12 and second friction members 22, and in the first direction (y direction), the first fixing member 11 and the second fixing member 21 can be located on both sides of the friction member group.

[0261] Alternatively, in the first direction (y direction), the first fixing member 11, the second fixing member 21, and the friction member group can be distributed sequentially. Alternatively, in some examples, there can be partial first friction members 12 and second friction members 22 between the first fixing member 11 and the second fixing member 21, and the first friction members 12 and second friction members 22 can also be distributed on opposite sides of the first fixing member 11 and the second fixing member 21.

[0262] Alternatively, in some examples, along the first direction (y direction), a portion of the first fastener 11 may be located between the second fasteners 21, and the first friction member 12 and the second friction member 22 may be located between the second fasteners 21.

[0263] Figure 15 for Figure 10 A front view structural diagram of the rotating shaft mechanism in the diagram.

[0264] For example, see Figure 15As shown, the first fixing member 11 may include a first mating part 111 and a second mating part 113. The second fixing member 21 may include a third mating part 211 and a fourth mating part 213. In the first direction (y direction), the third mating part 211 and the fourth mating part 213 may be located between the first mating part 111 and the second mating part 113, respectively.

[0265] The first fixing member 11 may further include a first mounting portion 112 and a second mounting portion 114. The first mounting portion 112 is connected to the first mating portion 111, and the second mounting portion 114 is connected to the second mating portion 113. The first mounting portion 112 and the second mounting portion 114 can be fixedly assembled with the first housing, respectively. The first mating portion 111 can be a portion of the first fixing member 11 that slides with the third mating portion 211, and the second mating portion 113 is a portion of the first fixing member 11 that slides with the fourth mating portion 213. The first mounting portion 112 and the second mounting portion 114 are respectively portions of the first fixing member 11 that are assembled and connected to the first housing of the electronic device.

[0266] The first mounting part 112 and the first mating part 111 can be an integral structural component, which simplifies the structural design and reduces the size of the rotating shaft mechanism 103. Alternatively, in some examples, the first mounting part 112 and the first mating part 111 can also be two independent structural components, which can be assembled together by means of threaded fastening, adhesive connection, snap-fit ​​connection, etc.

[0267] Correspondingly, the second mounting part 114 and the second mating part 113 can also be an integral structural component, further simplifying the structural design. Alternatively, in some examples, the second mounting part 114 and the second mating part 113 can also be two independent structural components.

[0268] The second fixing member 21 may further include a third mounting portion 212 and a fourth mounting portion 214. The third mounting portion 212 is connected to the third mating portion 211, and the fourth mounting portion 214 is connected to the fourth mating portion 213. The third mounting portion 212 and the fourth mounting portion 214 can be fixedly assembled with the second housing 102, respectively. The third mating portion 211 can be a portion of the second fixing member 21 that slides with the first mating portion 111, and the fourth mating portion 213 can be a portion of the second fixing member 21 that slides with the second mating portion 113. The third mounting portion 212 and the fourth mounting portion 214 are respectively portions of the second fixing member 21 that are assembled and connected to the second housing of the electronic device.

[0269] The third mounting part 212 and the third mating part 211 can be an integral structural component, which simplifies the structural design and reduces the size of the rotating shaft mechanism 103. Alternatively, in some examples, the third mounting part 212 and the third mating part 211 can also be two independent structural components, which can be assembled together by means of threaded fastening, adhesive connection, snap-fit ​​connection, etc.

[0270] Correspondingly, the fourth mounting part 214 and the fourth mating part 213 can also be an integral structural component, further simplifying the structural design. Alternatively, in some examples, the fourth mounting part 214 and the fourth mating part 213 can also be two independent structural components.

[0271] In some examples, the first fixing member 11 and the second fixing member 21 can be rotatably connected, such as by the first fixing member 11 and the second fixing member 21 being rotatably engaged by a second sliding structure.

[0272] For example, a second sliding structure 321 may be provided between the first mating portion 111 of the first fixing member 11 and the third mating portion 211 of the second fixing member 21. A second sliding structure 322 may be provided between the second mating portion 113 of the first fixing member 11 and the fourth mating portion 213 of the second fixing member 21. Wherein, Figure 15 The diagram shows two second sliding structures 321 between the first mating part 111 and the third mating part 211, and two second sliding structures 322 between the second mating part 113 and the fourth mating part 213.

[0273] The second sliding structure improves the rotational stability of the first fixing member 11 and the second fixing member 21, and also increases the contact friction area between the first fixing member 11 and the second fixing member 21, thereby increasing the rotational friction between the first rotating assembly 10 and the second rotating assembly 20, and ensuring that the rotating shaft mechanism 103 can provide stable torque. Furthermore, by dividing the first fixing member 11 into a first mating part 111 and a second mating part 113, and the second fixing member 21 into a third mating part 211 and a fourth mating part 213, stable assembly with the first friction member 12 and the second friction member 22 is facilitated, and the friction between the first fixing member 11 and the second fixing member 21 is further increased, thus providing stable torque.

Figure 15a This is a schematic diagram of the disassembled structure from a viewpoint along the direction from the third mating part 211 toward the first mating part 111. Figure 15b This is a schematic diagram of the split structure from the perspective of the direction from the first mating part 111 toward the third mating part 211.

[0275] The second sliding structure may include a slidingly engaged second arc-shaped slider and a second arc-shaped groove. For example, see... Figure 15a As shown, taking the first mating part 111 and the third mating part 211 having two second sliding structures as an example, such as the first mating part 111 and the third mating part 211 having a first adapter 50a, so that the first mating part 111 and the first adapter 50a have a second sliding structure 321a, and the first adapter 50a and the third mating part 211 have a second sliding structure 321b.

[0276] Combination Figure 15a and Figure 15b As shown, the second sliding structure 321a may include a second arc-shaped slider 51 and a second arc-shaped groove 1111. For example, the first mating part 111 may have a second arc-shaped groove 1111 on the side facing the first adapter 50a, and the first adapter 50a may have a raised second arc-shaped slider 51 on the side facing the first mating part 111. The second sliding structure 321b may include a second arc-shaped slider 52 and a second arc-shaped groove 2111. For example, the first adapter 50a may have a raised second arc-shaped slider 52 on the side facing the third mating part 211, and the third mating part 211 may have a second arc-shaped groove 2111 on the side facing the first adapter 50a.

[0277] The second arc-shaped slider 51 can slide along the second arc-shaped slide groove 1111, and the second arc-shaped slider 52 can slide along the second arc-shaped slide groove 2111, so that the first mating part 111 and the third mating part 211 can be slidably connected through the two second sliding structures, and the first mating part 111 and the third mating part 211 can rotate relative to each other.

[0278] It should be noted that in some other examples, the first mating part 111 and the third mating part 211 may only have a second sliding structure, and the first adapter 50a may not be provided between the first mating part 111 and the third mating part 211. For example, on the two opposite sides of the first mating part 111 and the third mating part 211, one side may have a second arc-shaped groove, and the other side may have a protruding second arc-shaped slider. The second arc-shaped groove and the second arc-shaped slider constitute a second sliding structure. The second arc-shaped slider can be inserted into the second arc-shaped groove and slide along the second arc-shaped groove, so that the first mating part 111 and the third mating part 211 can achieve rotational engagement through a second sliding structure.

[0279] Figure 15c for Figure 15A schematic diagram of the split structure of the second and fourth mating parts from one perspective. Figure 15d for Figure 15 A schematic diagram of the split structure of the second and fourth mating parts from another perspective. Among them, Figure 15c This is a schematic diagram of the disassembled structure from a viewpoint along the direction from the second mating part 113 toward the fourth mating part 213. Figure 15d This is a schematic diagram of the split structure from the perspective of the direction from the fourth mating part 213 toward the second mating part 113.

[0280] For example, see Figure 15c As shown, there are two second sliding structures between the second mating part 113 and the fourth mating part 213. For example, a second adapter 50b may be provided between the second mating part 113 and the fourth mating part 213, so that there is a second sliding structure 322a between the second mating part 113 and the second adapter 50b, and a second sliding structure 322b between the second adapter 50b and the fourth mating part 213.

[0281] Combination Figure 15c and Figure 15d As shown, the second sliding structure 322a may include a second arc-shaped slider 53 and a second arc-shaped groove 1131. For example, the second adapter 50b may also have a protruding second arc-shaped slider 53 on the side facing the second mating part 113, and the second mating part 113 may have a second arc-shaped groove 1131 on the side facing the second adapter 50b. The second sliding structure 322b may include a second arc-shaped slider 54 and a second arc-shaped groove 2131. For example, the fourth mating part 213 may have a second arc-shaped groove 2131 on the side facing the second adapter 50b, and the second adapter 50b may have a protruding second arc-shaped slider 54 on the side facing the fourth mating part 213.

[0282] The second arc-shaped slider 53 can slide along the second arc-shaped slide groove 1131, and the second arc-shaped slider 54 can slide along the second arc-shaped slide groove 2131, so that the second mating part 113 and the fourth mating part 213 can be slidably connected through the two second sliding structures, and the second mating part 113 and the fourth mating part 213 can rotate relative to each other.

[0283] It should be noted that in some other examples, the fourth mating part 213 and the second mating part 113 may only have one second sliding structure, and the second adapter may not be provided between the fourth mating part 213 and the second mating part 113. For example, on the two opposite sides of the second mating part 113 and the fourth mating part 213, one side may have a second arc-shaped groove, and the other side may have a protruding second arc-shaped slider. The second arc-shaped groove and the second arc-shaped slider constitute a second sliding structure. The second arc-shaped slider can be inserted into the second arc-shaped groove and slide along the second arc-shaped groove, so that the second mating part 113 and the fourth mating part 213 achieve rotational engagement through a second sliding structure.

[0284] It is understandable that when the torsion structure 40 presses the first rotating assembly and the second rotating assembly along the first direction (y direction), it will also press the first fixing member 11 and the second fixing member 21, increasing the frictional force between the first fixing member 11 and the second fixing member 21 in relative rotation.

[0285] The shape of the second arc-shaped groove can be the same as that of the first arc-shaped groove. The shapes of the second arc-shaped groove and the second arc-shaped slider can be circular arc, elliptical arc, etc. The center of the second arc-shaped groove can coincide with the center of the first arc-shaped groove in the first direction (y direction), so that the rotation axis of the first fixing member 11 and the second fixing member 21 that rotate relative to each other is consistent with the rotation axis of the first friction member 12 and the second friction member 22 that rotate relative to each other, ensuring that the first rotating assembly 10 and the second rotating assembly 20 rotate relative to each other around the virtual axis.

[0286] The first friction member 12 and the second friction member 22 are respectively located between the third mating portion 211 and the fourth mating portion 213. In some examples, among the plurality of first friction members 12 and second friction members 22, one of the first friction members may be disposed adjacent to the third mating portion 211, and one of the second friction members may be disposed adjacent to the fourth mating portion 213.

[0287] The first friction member adjacent to the third mating part 211 can be rotatably engaged with the third mating part 211, and the first friction member adjacent to the fourth mating part 213 can be rotatably engaged with the fourth mating part 213. For example, the first friction member can be rotatably engaged with the third mating part 211, and the first friction member can be rotatably engaged with the fourth mating part 213, respectively, through a third sliding structure.

[0288] For example, in the first direction (y direction), the first friction member 12a located at the head end of the array of first friction members 12 and second friction members 22 can be positioned closer to the third mating part 211 (see reference). Figure 15As shown), the first friction member 12d at the tail end can be disposed closer to the fourth mating part 213. A third sliding structure 331 can be provided between the first friction member 12a and the third mating part 211. A third sliding structure 332 can be provided between the first friction member 12d and the fourth mating part 213. Figure 15 The diagram shows two third sliding structures 331 between the first friction member 12a and the third mating part 211, and two third sliding structures 332 between the first friction member 12d and the fourth mating part 213.

[0289] The third sliding structure can further increase the contact friction area between the first rotating component 10 and the second rotating component 20, improve the friction of their rotation, ensure the high stability and high strength of the torque of the rotating shaft mechanism 103, and better improve the opening, closing and hovering effect of the electronic device.

[0290] Figure 15e for Figure 15 A schematic diagram of the disassembled structure of the first friction component and the third mating part from a certain perspective. Figure 15f for Figure 15 A schematic diagram of the disassembled structure of the first friction component and the third mating part from another perspective. Figure 15e This is a schematic diagram of the disassembled structure from a viewpoint along the direction from the first friction space 12a toward the third mating part 211. Figure 15b This is a schematic diagram of the split structure from a perspective along the direction from the third mating part 211 toward the first friction member 12a.

[0291] The third sliding structure may include a slidingly fitted third arc-shaped slider and a third arc-shaped groove, for example, see [link to example]. Figure 15e As shown, taking the two third sliding structures between the first friction member 12a and the third mating part 211 as an example, a third adapter 60a can be provided between the first friction member 12a and the third mating part 211, so that a third sliding structure 331a can be provided between the first friction member 12a and the third adapter 60a, and a third sliding structure 331b can be provided between the third adapter 60a and the third mating part.

[0292] Combination Figure 15e and Figure 15fAs shown, the third sliding structure 331a may include a third arc-shaped groove 121 and a third arc-shaped slider 62. For example, the surface of the third adapter 60a facing the first friction member 12a may have a raised third arc-shaped slider 62, and the surface of the first friction member 12a facing the third adapter 60a may have a third arc-shaped groove 121. The third sliding structure 331b may include a third arc-shaped groove 2112 and a third arc-shaped slider 61. For example, the surface of the third mating part 211 facing the third adapter 60a may have a third arc-shaped groove 2112, and the surface of the third adapter 60a facing the third mating part 211 may have a raised third arc-shaped slider 61.

[0293] The third arc-shaped slider 62 can slide along the third arc-shaped slide groove 121, and the third arc-shaped slider 61 can slide along the third arc-shaped slide groove 2112, so that the first friction member 12a and the third mating part 211 can be slidably connected through the two third sliding structures, and the third mating part 211 and the first friction member 12a can rotate relative to each other.

[0294] It should be noted that in some other examples, the third mating part 211 and the first friction member 12a may only have one third sliding structure, and the third adapter may not be provided between the third mating part 211 and the first friction member 12a. For example, on the two opposite sides of the third mating part 211 and the first friction member 12a, one side may have a third arc-shaped groove, and the other side may have a raised third arc-shaped slider. The third arc-shaped groove and the third arc-shaped slider constitute a third sliding structure. The third arc-shaped slider can be inserted into the third arc-shaped groove and slide along the third arc-shaped groove, so that the third mating part 211 and the first friction member 12a can achieve rotational engagement through a third sliding structure.

[0295] Figure 15g for Figure 15 A schematic diagram of the disassembled structure of the first friction component and the fourth mating part from one perspective. Figure 15h for Figure 15 A schematic diagram of the disassembled structure of the first friction component and the fourth mating part from another perspective. Among them, Figure 15g This is a schematic diagram of the disassembled structure from a viewpoint along the direction from the fourth mating part 213 toward the first friction member 12d. Figure 15h This is a schematic diagram of the split structure from a perspective along the direction from the first friction member 12d toward the fourth mating part 213.

[0296] For example, see Figure 15gAs shown, there are two third sliding structures between the fourth mating part 213 and the first friction member 12d. For example, a fourth adapter 60b can be provided between the fourth mating part 213 and the first friction member 12d, so that there is a third sliding structure 332b between the first friction member 12d and the fourth adapter 60b, and a third sliding structure 332a between the fourth adapter 60b and the first friction member 12d.

[0297] Combination Figure 15g and Figure 15h As shown, the third sliding structure 332a may include a third arc-shaped groove 2132 and a third arc-shaped slider 63. For example, the fourth mating part 213 may have a third arc-shaped groove 2132 on the side facing the fourth adapter 60b, and the fourth adapter 60b may have a raised third arc-shaped slider 63 on the side facing the fourth mating part 213. The third sliding structure 332b may include a third arc-shaped groove 125 and a third arc-shaped slider 63. For example, the fourth adapter 60b may have a raised third arc-shaped slider 64 on the side facing the first friction member 12d, and the first friction member 12d may have a third arc-shaped groove 125 on the side facing the fourth adapter 60b.

[0298] The third arc-shaped slider 63 can slide along the third arc-shaped slide groove 2132, and the third arc-shaped slider 64 can slide along the third arc-shaped slide groove 125, so that the fourth mating part 213 and the first friction member 12d can be slidably connected through the two third sliding structures, and the fourth mating part 213 and the first friction member 12d can rotate relative to each other.

[0299] In some other examples, there may only be one third sliding structure between the first friction member 12d and the fourth mating part 213, and no fourth adapter may be provided between them. For example, on the two opposing sides of the fourth mating part 213 and the first friction member 12b, one side may have a third arc-shaped groove, and the other side may have a raised third arc-shaped slider. The third arc-shaped groove and the third arc-shaped slider constitute a third sliding structure, and the third arc-shaped slider can be inserted into the third arc-shaped groove and slide along it, so that the fourth mating part 213 and the first friction member 12d can achieve rotational engagement through a third sliding structure.

[0300] When the torsion structure 40 presses the first rotating assembly 10 and the second rotating assembly 20 along the first direction (y direction), it will also press the third mating part 211 and the first friction member 12a, the fourth mating part 213 and the first friction member 12d, increasing the rotational friction of the rotating shaft mechanism 103.

[0301] The shape of the third arc-shaped groove can be the same as that of the first arc-shaped groove. The shape of the third arc-shaped groove can be circular, elliptical, etc. The center of the third arc-shaped groove can coincide with the center of the first arc-shaped groove in the first direction (y direction), so that the rotation axis of the relative rotation between the third mating part 211 and the first friction member 12a, the rotation axis of the relative rotation between the fourth mating part 213 and the first friction member 12d, and the rotation axis of the relative rotation between the first friction member and the second friction member are consistent, ensuring that the first rotating assembly 10 and the second rotating assembly 20 rotate relative to each other around the virtual axis.

[0302] As described above, there can be only one first sliding structure 31 between adjacent first friction member 12 and second friction member 22, and only one second sliding structure between first mating part 111 and third mating part 211, and only one second sliding structure between fourth mating part 213 and second mating part 113. There can also be only one third sliding structure between third mating part 211 and first friction member 12a, and only one third sliding structure between first friction member 12d and fourth mating part 213.

[0303] Figure 16 This is a schematic diagram of the 15-axis rotating mechanism in an intermediate state from another perspective. Figure 17a for Figure 15 A schematic diagram of a partially disassembled structure of the central shaft mechanism.

[0304] Or, in some examples, combined Figure 16 and Figure 17a As shown, the rotating shaft mechanism 103 may further include a first adapter 50a and a second adapter 50b. The first fixing member 11 and the second fixing member 21 can be rotatably connected through the first adapter 50a, the second adapter 50b, and multiple second sliding structures. The shape and structure of the first adapter 50a and the second adapter 50b may be the same.

[0305] The first adapter 50a is located between the first mating part 111 and the third mating part 211, and the first adapter 50a has a second sliding structure with both the first mating part 111 and the third mating part 211. For example, on the two sides of the first adapter 50a opposite to the first mating part 111, one side may have a second arc-shaped groove, and the other side may have a raised second arc-shaped slider. Similarly, on the two sides of the first adapter 50a opposite to the third mating part 211, one side may have a second arc-shaped groove, and the other side may have a raised second arc-shaped slider.

[0306] For example, a second sliding structure 321a may be provided between the first adapter 50a and the first mating part 111 (see reference). Figure 15a and Figure 15b As shown, the first mating part 111 and the first adapter 50a can rotate relative to each other through the second sliding structure 321a. The first adapter 50a and the third mating part 211 can have a second sliding structure 321b, so that the first adapter 50a and the third mating part 211 can rotate relative to each other through the second sliding structure 321b.

[0307] See also Figure 17a As shown, the second adapter 50b is located between the fourth mating part 213 and the second mating part 113, and both the second adapter 50b and the fourth mating part 213 and the second mating part 113 have a second sliding structure. For example, on one side of the fourth mating part 213 and the two sides opposite to the second adapter 50b, a second arc-shaped groove may be provided, and on the other side, a raised second arc-shaped slider may be provided. Similarly, on one side of the second adapter 50b and the two sides opposite to the second mating part 113, a second arc-shaped groove may be provided, and on the other side, a raised second arc-shaped slider may be provided.

[0308] For example, a second sliding structure 322b may be provided between the second adapter 50b and the fourth mating part 213 (see reference). Figure 15c and Figure 15d As shown), the fourth mating part 213 and the second adapter 50b can rotate relative to each other through the second sliding structure 322b. The second adapter 50b and the second mating part 113 can also have a second sliding structure 322a, so that the second adapter 50b and the second mating part 113 can also rotate relative to each other through the second sliding structure 322a.

[0309] See Figure 16 As shown, when the rotating shaft mechanism 103 switches from the open state to the closed state, causing the electronic device to switch from the closed state to the open state, the second fixing member 21 rotates relative to the first fixing member 11. The third mating part 211 and the fourth mating part 213 can rotate relative to the first adapter 50a and the second adapter 50b, respectively. The first adapter 50a and the second adapter 50b can rotate relative to the first mating part 111 and the second mating part 113, respectively. This increases the rotatable trajectory of the third mating part 211 and the fourth mating part 213 relative to the second mating part 113 and the first mating part 111. For example, under the condition that the size of the second arc-shaped slide is relatively small, a larger rotation trajectory can be obtained. This allows for a larger relative rotation angle between the second fixing member 21 and the first fixing member 11, enabling the electronic device to have a larger opening angle and facilitating a reduction in the size of the rotating shaft mechanism 103.

[0310] In addition, the arrangement of the first adapter and the second adapter helps to increase the rotational friction of the first rotating component 10 and the second rotating component 20, thereby increasing the torque of the rotating shaft mechanism 103 and ensuring that the rotating shaft mechanism 103 can provide a stable torque for the opening and closing of the electronic device.

[0311] Figure 17b for Figure 15 A schematic diagram of another partially disassembled structure of the central shaft mechanism.

[0312] See in some examples Figure 17b As shown, the rotating shaft mechanism 103 may further include a third adapter 60a and a fourth adapter 60b. The third mating part 211 and the first friction member 12a, and the fourth mating part 213 and the first friction member 12d, can be rotatably connected through the third adapter 60a, the fourth adapter 60b, and multiple third sliding structures, respectively. The shape and structure of the third adapter 60a and the fourth adapter 60b may be identical.

[0313] The third adapter 60a can be located between the third mating part 211 and the first friction member 12a, and the third adapter 60a has a third sliding structure with both the third mating part 211 and the first friction member 12a. For example, on the two opposing sides of the third mating part 211 and the third adapter 60a, one side can have a third arc-shaped groove, and the other side can have a raised third arc-shaped slider. On the two opposing sides of the third adapter 60a and the first friction member 12a, one side can have a second arc-shaped groove, and the other side can have a raised second arc-shaped slider.

[0314] For example, a third sliding structure 331b may be provided between the third adapter 60a and the third mating part 211 (see reference). Figure 15e and Figure 15f As shown), the third mating part 211 and the third adapter 60a can rotate relative to each other through the third sliding structure 331b. The third adapter 60a and the first friction member 12a can have a third sliding structure 331a, so that the third adapter 60a and the first friction member 12a can rotate relative to each other through the third sliding structure 331a.

[0315] See also Figure 17bAs shown, the fourth adapter 60b can be located between the first friction member 12d and the fourth mating part 213. The fourth adapter 60b has a third sliding structure with both the first friction member 12d and the fourth mating part 213. For example, on one of the opposing sides of the fourth mating part 213 and the fourth adapter 60b, a third arc-shaped groove can be provided, and on the other side, a raised third arc-shaped slider can be provided. On one of the opposing sides of the fourth adapter 60b and the first friction member 12d, a second arc-shaped groove can be provided, and on the other side, a raised second arc-shaped slider can be provided.

[0316] For example, a third sliding structure 332b may be present between the fourth adapter 60b and the first friction member 12d (see reference). Figure 15g and Figure 15h As shown, the first friction member 12d and the fourth adapter 60b can rotate relative to each other through the third sliding structure 332b. The fourth adapter 60b and the fourth mating part 213 can have a third sliding structure 332a, so that the third adapter 60a and the fourth mating part 213 can rotate relative to each other through the third sliding structure 332a.

[0317] See Figure 16 As shown, when the rotating shaft mechanism 103 switches from the open state to the closed state, the second fixing member 21 rotates relative to the first fixing member 11. The third mating part 211 and the fourth mating part 213 can rotate relative to the third adapter 60a and the fourth adapter 60b, respectively. The third adapter 60a and the fourth adapter 60b can rotate relative to the first friction member 12a and the first friction member 12d, respectively, increasing the rotation trajectory of the third mating part 211 and the fourth mating part 213 relative to the first friction member 12a and the second friction member 22d. Even with a smaller size design for the third arc-shaped slide groove, a larger rotation trajectory can be obtained. By reducing the size of the rotating shaft mechanism 103, the electronic device can have a larger opening angle. Furthermore, it can further increase the frictional force of the relative rotation of the first rotating assembly 10 and the second rotating assembly 20, enhancing the torque of the rotating shaft mechanism 103.

[0318] In some examples, the rotating shaft mechanism 103 may also include a fifth adapter, which may be the sliding adapter 70 described above. Adjacent first friction members 12 and second friction members 22 may be rotatably connected via the fifth adapter and multiple first sliding structures, respectively. The shape and structure of the fifth adapter may be the same as those of the third adapter 60a and the fourth adapter 60b.

[0319] For example, see [link to previous article] Figure 17bAs shown, taking a fifth adapter 70a between adjacent first friction member 12a and second friction member 22a as an example, the fifth adapter 70a can be located between the first friction member 12a and the second friction member 22a, and the fifth adapter 70a has a first sliding structure with both the first friction member 12a and the second friction member 22a. For example, on the two opposing sides of the first friction member 12a and the fifth adapter, one side can have a first arc-shaped groove, and the other side can have a raised first arc-shaped slider. Similarly, on the two opposing sides of the fifth adapter and the second friction member 22a, one side can have a first arc-shaped groove, and the other side can have a raised first arc-shaped slider.

[0320] For example, the fifth adapter 70a and the first friction member 12a may have a first sliding structure 31b (see reference). Figure 10a and Figure 10b As shown), the first friction member 12a and the fifth adapter 70a can rotate relative to each other through the first sliding structure 31b. The fifth adapter 70a and the second friction member 22a can also have a first sliding structure 31a, so that the fifth adapter 70a and the second friction member 22a can rotate relative to each other through the first sliding structure 31a.

[0321] When the rotating shaft mechanism 103 switches from the open state to the closed state, the second fixing member 21 rotates relative to the first fixing member 11. The third mating part 211 drives the first friction member 12a to rotate relative to the fifth adapter 70a. The fifth adapter 70a can rotate relative to the second friction member 22a, increasing the rotation trajectory of the first friction member 12 and the second friction member 22 relative to each other. Even with a relatively small size design for the first arc-shaped slide groove, a larger rotation trajectory can be obtained, ensuring that the electronic device has a larger opening angle. This also facilitates the miniaturization of the rotating shaft mechanism 103 and increases the torque of the rotating shaft mechanism 103.

[0322] Specifically, in the example of a rotating shaft mechanism including the aforementioned first adapter, second adapter, third adapter, fourth adapter, and fifth adapter. See [link / reference]. Figure 17b As shown, a first adapter 50a is provided between the first mating part 111 and the third mating part 211, and a second adapter 50b is provided between the fourth mating part 213 and the second mating part 113. A third adapter 60a is provided between the third mating part 211 and the first friction member 12a, and a fourth adapter 60b is provided between the fourth mating part 213 and the first friction member 12d. A fifth adapter 70a is provided between adjacent first and second friction members; for example, taking the first friction member 12a and the second friction member 22a as an example, a fifth adapter 70a is provided between the first friction member 12a and the second friction member 22a.

[0323] When the torsion structure 40 presses against the first rotating assembly and the second rotating assembly along the first direction (y-direction), it also presses against the structural components that are slidably engaged by the first sliding structure, the second sliding structure, and the third sliding structure. For example, if the torsion structure 40 is located between the first friction component 12 and the second friction component 22 in the figure, the torsion structure 40 will push a portion of the first friction component 12, a portion of the second friction component 22, the third mating part 211, the first mating part 111, and other structural components, as well as the connecting parts between these structural components, to the left along the first direction (y-direction). It will also push a portion of the second friction component 22, a portion of the first friction component 12, the fourth mating part 213, the second mating part 113, and other structural components to the right along the first direction (y-direction), increasing the rotational friction between the structural components.

[0324] In this embodiment, to achieve synchronous rotation among the structural components of the first and second rotating assemblies, the first fixing member 11 and multiple first friction members 12 in the first rotating assembly can be connected together, and the second fixing member 21 and multiple second friction members 22 in the second rotating assembly can also be connected together. This allows the second fixing member 21 and multiple second friction members 22 to rotate synchronously relative to the first fixing member 11 and multiple first friction members 12 as a whole, ensuring the relative rotation of the first and second rotating assemblies around the virtual axis and guaranteeing the opening and closing effect of the electronic device.

[0325] For example, the first rotating assembly may further include a first connecting rod 13, and the first fixing member 11 and multiple first friction members 12 can be connected together through the first connecting rod 13. It should be noted that the first connecting rod 13 is assembled with the first fixing member 11 and the first friction members 12 in a movable and adjustable manner, allowing the first fixing member 11 and the first friction members 12 to slide along the first connecting rod 13, facilitating assembly. Furthermore, it ensures that during assembly or torque adjustment, the first fixing member 11 and the first friction members 12 can move relative to each other along a first direction (y-direction), achieving the effect of pressing the first fixing member 11 and the first friction members 12.

[0326] For example, each first friction element 12 may have a first mounting hole at one end (e.g., taking the first friction element 12a as an example, it has a first mounting hole 123), the first mounting portion 112 of the first fixing member 11 has a second mounting hole 1121, and the second mounting portion 114 has a third mounting hole (not shown in the figure). Multiple first friction elements 12 can pass through the first mounting holes 123 onto the first connecting rod 13. The two ends of the first connecting rod 13 can be respectively inserted into the second mounting hole 1121 of the first mounting portion 112 and the third mounting hole of the second mounting portion 114, connecting the first mounting portion 112, multiple first friction elements 12, and the second mounting portion 114 together. There may be gaps between the first connecting rod 13 and the first mounting holes 123, 1121, and 3, allowing the first fixing member 11 and the first friction elements 12 to slide relative to the first connecting rod 13 in a first direction (y-direction).

[0327] The second rotating assembly 20 may further include a second connecting rod 23, and the second fixing member 21 and multiple second friction members 22 can be connected together through the second connecting rod 23. The connection between the second connecting rod 23 and the second fixing member 21 and the second friction members 22 is also a movable assembly method. Under the action of external force, the second fixing member 21 and the second friction members 22 can slide along the second connecting rod 23 to ensure that the second fixing member 21 and the second friction members 22 can be squeezed to increase the rotational torque.

[0328] The assembly method of the second link 23 with the second fixing member 21 and the second friction member 22 can be referred to the assembly method of the first link 13 with the first fixing member 11 and the first friction member 12, and will not be repeated here.

[0329] To improve the stability of each adapter component, they can be connected together, for example. For instance, multiple fifth adapter components can be connected sequentially. Among these, one fifth adapter component adjacent to the third adapter component 60a can be connected to the third adapter component 60a, and another fifth adapter component adjacent to the fourth adapter component 60b can be connected to the fourth adapter component 60b. Connecting the first adapter component 50a, second adapter component 50b, third adapter component 60a, fourth adapter component 60b, and multiple fifth adapter components together reduces or avoids the risk of each adapter component detaching from the rotating shaft mechanism 103 during the rotation of the first and second rotating components. Furthermore, it allows the aforementioned adapter components to rotate synchronously, improving the opening and closing effect.

[0330] Figure 18 for Figure 17b A front view diagram of the assembly of the first adapter, second adapter, third adapter, and exterior parts.

[0331] Among them, see Figure 18As shown, in the first direction (y direction), the first adapter 50a, the third adapter 60a, a plurality of fifth adapters, the fourth adapter 60b, and the second adapter 50b are sequentially distributed. For example, the first adapter 50a, the third adapter 60a, the plurality of fifth adapters, the fourth adapter 60b, and the second adapter 50b can be sequentially inserted together.

[0332] To avoid affecting the rotation of the first fixing member 11, the second fixing member 21, the first friction member 12, and the second friction member 22, the adapters can be connected together by inserting them together in a tail-joint manner.

[0333] For example, the first adapter 50a may include a first end and a second end opposite to each other. The first end and the second end may be located at opposite ends of the first adapter 50a along the rotation direction (the direction in which the first adapter 50a rotates), that is, the first end and the second end are respectively located at opposite ends of the extension direction of the second arc-shaped groove on the first adapter 50a. Correspondingly, the second adapter 50b, the third adapter 60a, the fourth adapter 60b, and the fifth adapter may also include a first end and a second end opposite to each other in the rotation direction.

[0334] See Figure 18 As shown, taking the second adapter 50b and the second adapter 50b as an example, the multiple fifth adapters include the fifth adapter 70a, the fifth adapter 70b, the fifth adapter 70c, the fifth adapter 70d, and the fifth adapter 70e, respectively. The fifth adapter 70a is adjacent to the third adapter 60a, and the fifth adapter 70e is adjacent to the fourth adapter 60b.

[0335] The first end of the first adapter 50a can be plugged into the first end of the third adapter 60a via the first connector 55. The second end of the third adapter 60a can be plugged into the first end of the adjacent fifth adapter 70a via the second connector 65. The second end of the fifth adapter 70a can be plugged into the first end of the adjacent fifth adapter 70b via the third connector 73. The connection methods of the fifth adapters 70b, 70d, and 70e are similar.

[0336] The first end of the fourth adapter 60b can be plugged into the first end of the adjacent fifth adapter 70e through the fourth connector 66, and the second end of the second adapter 50b can be plugged into the second end of the fourth adapter 60b through the fifth connector 56.

[0337] In the sequentially distributed first connector 55, second connector 65, multiple third connectors, fourth connector 66, and fifth connector 56, any two adjacent connectors are staggered in the first direction (y-direction), and their projections in the first direction (y-direction) do not coincide. Adjacent connectors refer to two connectors that are adjacent in arrangement order among the aforementioned sequentially distributed connectors. For example, first connector 55 and second connector 65 are adjacent, second connector 65 is adjacent to third connector 73, and so on. Taking first connector 55 and second connector 65 as an example, first connector 55 and second connector 65 are located on opposite sides of second adapter 50b, and are staggered in the first direction (y-direction).

[0338] This arrangement connects the first adapter 50a, third adapter 60a, fifth adapter 70a, fifth adapter 70b, fifth adapter 70c, fifth adapter 70d, fifth adapter 70e, fourth adapter 60b, and second adapter 50b in an S-shaped (as shown by the dotted line in the figure) manner, ensuring the stability of each adapter's configuration. Furthermore, the adjacent connectors are staggered, allowing sufficient space between them to avoid obstructing the third mating part 211, the first friction element 12, the second friction element 22, and the fourth mating part 213. This improves the integration of the rotating shaft mechanism 103 and facilitates its miniaturization.

[0339] The first adapter 50a and the third adapter 60a may each have a protruding first plug-in 55, while the other may have a first plug-in groove that mates with the first plug-in 55. The connection between the first adapter 50a and the third adapter 60a is achieved through the plug-in engagement of the first plug-in 55 and the first plug-in groove. The structure is simple in design and easy to manufacture and assemble.

[0340] Correspondingly, one of the third adapter 60a and the fifth adapter 70a may have a protruding second plug 65, and the other may have a second plug groove that mates with the second plug 65. The connection between the third adapter 60a and the fifth adapter 70a can be achieved through the plug-in engagement of the second plug 65 and the second plug groove.

[0341] Of the two connected fifth adapters, one of the fifth adapters may have a protruding third connector, and the other fifth adapter may have a third connector groove that mates with the third connector. The connection between the fifth adapters is achieved through the insertion and mating of the third connector and the third connector groove.

[0342] Figure 19 for Figure 15 A cross-sectional schematic diagram of the central rotating shaft mechanism.

[0343] For example, see Figure 19 As shown, taking the first adapter 50a and the third adapter 60a connected as an example, the first end of the first adapter 50a may have a protruding first connector 55 (see reference). Figure 17a As shown), the third adapter 60a may have a first insertion slot 67, and the first insertion member 55 may be inserted into the first insertion slot 67.

[0344] The first connector 55 can be a protruding columnar structure, and one end of the first connector 55 can be inserted into the first connector slot 67.

[0345] Alternatively, in some examples, the first connector 55 may include a support portion 551 and a plug-in protrusion 552. The support portion 551 may be a columnar structural member and may be connected to the first adapter 50a, such as the first end of the first adapter 50a being provided with the support portion 551.

[0346] The insertion protrusion 552 can be provided on the end face of the support portion 551 facing away from the first adapter 50a. The insertion protrusion 552 can be inserted into the first insertion groove 67, which ensures the connection between the adapters while making the size of the insertion protrusion 532 and the first insertion groove 67 smaller, thereby reducing the overall size of the third adapter 60a.

[0347] In the first direction (y-direction), the third mating part 211 is located between the first adapter 50a and the second adapter 50b, and a first clearance groove 2113 may be provided on the third mating part 211 (see reference). Figure 17a (As shown). In the first direction (y direction), the first clearance groove 2113 can penetrate the third mating part 211, and the first clearance groove 2113 is used to avoid the first plug-in member 55.

[0348] See also Figure 19 As shown, when the rotating shaft mechanism 103 is in the open state, the first connector 55 can be located in the first clearance groove 2113. One end of the first connector 55 is connected to the first adapter 50a, and the other end of the first connector 55 passes through the first clearance groove 2113 and is inserted into the first connector groove 67 of the third adapter 60a. This improves the compactness of the layout of the first adapter 50a, the third mating part 211, and the third adapter 60a, thereby improving the overall compactness of the rotating shaft mechanism 103 and facilitating miniaturization.

[0349] When the rotating shaft mechanism 103 switches from the open state to the closed state, the third mating part 211, the first adapter 50a and the third adapter 60a rotate, causing the first plug 55 to slide out of the first plug groove 67, without affecting the rotation of the second rotating assembly relative to the first rotating assembly.

[0350] The insertion method of the second adapter 50b and the fourth adapter 60b can be the same as that of the first adapter 50a and the third adapter 60a. Refer to the first adapter 50a and the third adapter 60a for details. The structure of the fifth connector can refer to the first connector 55, and will not be repeated here. A fifth clearance groove for avoiding the fifth connector can be provided on the fourth mating part 213. The structure of the fifth clearance groove can refer to the first clearance groove 2113 of the third mating part 211.

[0351] Taking the connected third adapter 60a and fifth adapter 70a as an example, the third adapter 60a may have a protruding second connector 65 (see reference). Figure 17b As shown in the figure, the fifth adapter 70a may have a second insertion slot (not shown in the figure). The second insertion member 65 may be a raised columnar structure, or the second insertion member 65 may include a support portion and an insertion protrusion, as can be seen from the structure of the first insertion member 55, which will not be described again here.

[0352] In the first direction (y direction), the first friction member 12a is located between the third adapter 60a and the fifth adapter 70a, and a second clearance groove 124 can be formed on the first friction member 12a (see reference). Figure 17b As shown), the second clearance groove 124 is used to avoid the second connector 65.

[0353] See also Figure 19 As shown, when the rotating shaft mechanism 103 is in the open state, the second connector 65 can be located in the second clearance groove 124. When the rotating shaft mechanism 103 switches from the open state to the closed state, the second connector 65 slides out of the second clearance groove 124. Without affecting the rotation of the second rotating component, the layout compactness of the rotating shaft mechanism 103 is further improved.

[0354] The structure and connection method of the fourth adapter 60b and the fifth adapter 70e can be the same as the insertion method of the third adapter 60a and the fifth adapter 70a, and can be referred to the third adapter 60a and the fifth adapter 70a. The structure of the fourth plug 66 can be referred to the second plug 65, and will not be described again here. The first friction member 12d may be provided with a third clearance groove 1210 for avoiding the fourth plug (refer to...). Figure 17b As shown, the structure of the third clearance groove 1210 can be referred to the second clearance groove 124 of the first friction member 12a.

[0355] Figure 20 for Figure 17b A schematic diagram of the disassembled structure of the two fifth adapters and the second friction component from one perspective. Figure 20a for Figure 17b A schematic diagram of the disassembled structure of the two fifth adapters and the second friction component from another perspective. Figure 20 This is a schematic diagram of the split structure from the perspective of the fifth adapter 70b towards the fifth adapter 70a. Figure 20a This is a schematic diagram of the split structure from the perspective of the fifth adapter 70a toward the fifth adapter 70b.

[0356] See Figure 20 As shown, taking the connected fifth adapter 70a and fifth adapter 70b as an example, the fifth adapter 70a may have a protruding third connector 73. Combined with... Figure 20a As shown, the first end of the fifth adapter 70b may have a third insertion slot 74. The third insertion member 73 may be a raised columnar structure, or the third insertion member 73 may include a support portion and an insertion protrusion, as can be seen from the structure of the first insertion member 55, which will not be described in detail here.

[0357] The second friction member 22a is located between the fifth adapter 70a and the fifth adapter 70b. A fourth clearance groove 222 may be provided on the second friction member 22a. The fourth clearance groove 222 is used to avoid the third plug-in member 73.

[0358] When the rotating shaft mechanism is in the open state, the third connector 173 can be located within the fourth clearance groove 222. When the rotating shaft mechanism switches from the open state to the closed state, the third connector 73 slides out of the fourth clearance groove 222, further improving the compactness of the rotating shaft mechanism layout without affecting the rotation of the second rotating component.

[0359] The structure and connection method of the other two adjacent fifth adapters among the multiple fifth adapters can be referred to as fifth adapter 70a and fifth adapter 70b, and will not be described in detail here. The first friction member and the second friction member between the fifth adapters may be provided with a fourth clearance groove for avoiding the third plug member, which can be referred to as the fourth clearance groove on the second friction member 22a, and will not be described in detail here either.

[0360] Figure 21 for Figure 10 A schematic diagram of the rear structure of the central rotating shaft mechanism.

[0361] See Figure 21 As shown, the rotating shaft mechanism 103 may further include an outer appearance component 80, and the first rotating assembly 10 and the second rotating assembly 20 may be assembled together with the outer appearance component 80. The outer appearance component 80 may be located on one side of a portion of the first rotating assembly 10 and a portion of the second rotating assembly 20, and the portion of the first rotating assembly 10 and the portion of the second rotating assembly 20 may be housed within the outer appearance component 80.

[0362] Figure 22 for Figure 10 A schematic diagram showing the disassembled external components, the first rotating assembly, and the second rotating assembly in the rotating shaft mechanism.

[0363] For example, see Figure 22 As shown, the exterior component 80 may have a cavity 80a inside, and one end of the exterior component 80 has an opening that communicates with the cavity 80a. At least a portion of each of the rotatingly fitted structural components, such as the first mating part 111, the second mating part 113, the third mating part 211, the fourth mating part 213, the first friction member 12, the second friction member 22, the first adapter 50a, the second adapter 50b, the third adapter 60a, the fourth adapter 60b, and the fifth adapter, may be located in the cavity 80a of the exterior component 80.

[0364] In some examples, the appearance component 80 may include an arcuate bottom wall 811, a first side wall 812 and a second side wall 813. In a first direction (y direction), the first side wall 812 and the second side wall 813 may be located on both sides of the arcuate bottom wall 811, and the first side wall 812, the second side wall 813 and the arcuate bottom wall 811 form a cavity 80a of the appearance component 80.

[0365] The first mating part 111, the second mating part 113, the third mating part 211, the fourth mating part 213, each of the first friction parts 12, each of the second friction parts 22, the first adapter 50a, the second adapter 50b, the third adapter 60a, the fourth adapter 60b, and each of the fifth adapters, etc., can be disposed between the first side wall 812 and the second side wall 813.

[0366] For example, the outer contour shape of the above-mentioned structural components can all be arc-shaped. When the rotating shaft mechanism 103 is in the open state, most of the first mating part 111, the second mating part 113, the third mating part 211, the fourth mating part 213, each of the first friction members 12, each of the second friction members 22, the first adapter 50a, the second adapter 50b, the third adapter 60a, the fourth adapter 60b, and each of the fifth adapters can be accommodated in the cavity 80a of the outer appearance part 80, thereby improving the local compactness of the entire rotating shaft mechanism 103.

[0367] The rotating mechanism 103 switches between an open state and a closed state, so that during the opening and closing of the electronic device 100, the second rotating component 20 rotates relative to the first rotating component 10, and the outer part 80 can also rotate relative to the first rotating component 10.

[0368] When the electronic device is in the closed state and the rotating shaft mechanism 103 is in the open state, the first rotating component 10, the outer appearance component 80 and part of the second rotating component 20 can be located in the assembly cavity of the edge of the first housing, and part of the second rotating component 20 can be connected to the second housing through the clearance hole on the edge.

[0369] When the electronic device switches from a closed state to an open state or an intermediate state, the second rotating component 20 rotates relative to the first rotating component 10, and the appearance component 80 also rotates relative to the first rotating component 10, so that the second rotating component 20 and the appearance component 80 slide out of the assembly cavity through the clearance hole.

[0370] When the electronic device is in the open state, the exterior component 80 can be located outside the assembly cavity. The exterior component 80 can cover the structural components of the pivot mechanism 103, improve the aesthetics of the pivot mechanism 103, and thus improve the aesthetics of the electronic device when it is in the open state.

[0371] To achieve rotational engagement between the first rotating assembly 10 and the exterior component 80, the exterior component 80 may include a first housing portion 81, a first assembly portion 82a, and a second assembly portion 82b. The first housing portion 81 may include the aforementioned arc-shaped bottom wall 811, first side wall 812, and second side wall 813. The shape and structure of the first assembly portion 82a may be the same as those of the second assembly portion 82b.

[0372] The first assembly part 82a may be disposed on the first side wall 812, and the first assembly part 82a may be adjacent to the first mating part 111, and the first mating part 111 and the first assembly part 82a are rotatably connected.

[0373] The second assembly part 82b can be disposed on the second side wall 813. The second assembly part 82b can be adjacent to the second mating part 113, and the second mating part 113 is rotatably connected to the second assembly part 82b. The first assembly part 82a and the second assembly part 82b are rotatably engaged with the first mating part 111 and the second mating part 113, respectively, to realize the rotatable engagement between the appearance part 80 and the first rotating assembly 10.

[0374] For example, the rotating shaft mechanism 103 may also include a fourth sliding structure, through which the outer part 80 can achieve rotational engagement with the first rotating assembly 10. For instance, a fourth sliding structure 34a may be provided between the first mating part 111 and the first assembly part 82a, allowing the first mating part 111 to rotate relative to the first assembly part 82a via the fourth sliding structure 34a.

[0375] For example, one of the opposing sides of the first mating part 111 and the first assembly part 82a may have a fourth arc-shaped groove, and the other side may have a fourth arc-shaped slider. For instance, the side of the first assembly part 82a facing the first mating part 111 (away from the first sidewall 812) may have a fourth arc-shaped slider 821a, and the side of the first mating part 111 facing the first assembly part 82a may have a fourth arc-shaped groove 1112. The fourth arc-shaped slider 821a can be inserted into the fourth arc-shaped groove 1112 and slide along the fourth arc-shaped groove 1112, thereby enabling rotation between the first mating part 111 and the first assembly part 82a.

[0376] A fourth sliding structure 34b may be provided between the second mating part 113 and the second assembly part 82b, so that the second mating part 113 can rotate relative to the second assembly part 82b through the fourth sliding structure 34b.

[0377] For example, one of the two opposing sides of the second mating part 113 and the second assembly part 82b may have a fourth arc-shaped groove, and the other side may have a fourth arc-shaped slider. For instance, the side of the second assembly part 82b facing the first mating part 111 (facing away from the first sidewall 812) may have a fourth arc-shaped slider 821b (the structure can be referred to as the fourth arc-shaped slider 821a on the first mating part 111), and the side of the second mating part 113 facing the first assembly part 82a may have a fourth arc-shaped groove 1132.

[0378] The fourth arc-shaped slider 821a can be inserted into the fourth arc-shaped slide groove 1132 and slide along the fourth arc-shaped slide groove 1132 to realize the rotation of the second mating part 113 and the second assembly part 82b. This allows the appearance part 80 to rotate relative to the first mating part 111 and the second mating part 113, thus realizing the rotation of the appearance part 80 relative to the first rotating assembly 10.

[0379] The fourth sliding structure enables rotational engagement between the outer part 80 and the first rotating component 10, and also increases the friction between the outer part 80 and the first rotating component 10 during the opening and closing of the rotating shaft mechanism 103, which helps to further improve the torque of the rotating shaft mechanism 103 and enable the rotating shaft mechanism 103 to provide a more stable torque.

[0380] The fourth arc-shaped groove (such as the fourth arc-shaped groove 1132) and the fourth arc-shaped slider (such as the fourth arc-shaped slider 821a) can be circular, elliptical, or other shapes. The shape of the fourth arc-shaped groove can be the same as that of the first arc-shaped groove, and the center of the fourth arc-shaped groove can coincide with the center of the first arc-shaped groove in the first direction (y direction), so that the rotation axis of the relative rotation of the appearance component 80 and the first rotating assembly 10 can be consistent with the virtual axis of relative rotation of the first rotating assembly 10 and the second rotating assembly 20.

[0381] The first assembly part 82a and the second assembly part 82b can be integrally formed with the first housing part 81, so that the appearance part 80 can be an integrally formed structural part.

[0382] Alternatively, in some examples, the first assembly part 82a, the second assembly part 82b and the first housing part 81 can be formed separately, and the first assembly part 82a and the second assembly part 82b can be assembled onto the first side wall 812 and the second side wall 813 of the first housing part 81 by means of plug-in connection.

[0383] Figure 23 for Figure 22 A breakdown diagram of the exterior and interior components.

[0384] For example, the insertion method of the first sidewall 812 and the first assembly part 82a, and the insertion method of the second sidewall 813 and the second assembly part 82b can be the same. See also Figure 23 As shown, taking the second sidewall 813 and the second assembly part 82b as examples, the second assembly part 82b may have a protruding insertion part 822, and an assembly groove 814 may be provided on the second sidewall 813 (refer to the assembly groove 814 on the first sidewall 812). The insertion part 822 may be inserted into the assembly groove 814, and the second assembly part 82b may be inserted into the second sidewall 813.

[0385] The second sidewall 813 may also have a protruding limiting portion 815 (refer to the limiting portion 815 on the first sidewall 812). The second assembly portion 82b may have a limiting groove 823. The shape of the limiting groove 823 may match the shape of the limiting portion 815, so that the limiting portion 815 can be inserted into the limiting groove 823. The insertion and engagement of the limiting groove 823 and the limiting portion 815 can limit the rotation between the second assembly portion 82b and the first housing portion 81, ensuring that the entire appearance part 80 can rotate relative to the first rotating assembly 10.

[0386] The limiting groove 823 extends from the side of the second assembly part 82b adjacent to the opening of the outer appearance part 80 to the side of the second assembly part 82b adjacent to the arc-shaped bottom wall 811, allowing the second assembly part 82b to be inserted into the limiting part 815 on the second side wall 813 from the opening side via the limiting groove 823. When the rotating shaft mechanism is in the open state, the limiting groove 823 extends through the second assembly part 82b in the thickness direction, allowing the second assembly part 82b to be inserted into the second side wall 813 from the opening slot of the outer appearance part in the thickness direction.

[0387] For example, the insertion part 822 can be located in the limiting groove 823, and the assembly groove 814 can be located on the limiting part 815. When the second assembly part 82b is inserted into the second side wall 813 from the opening side, when the assembly groove 814 on the second assembly part 82b is aligned with the insertion part 822, the insertion part 822 can be inserted into the assembly groove 814 to complete the assembly of the second assembly part 82b and the second side wall 813.

[0388] In actual assembly, for example, the first rotating assembly, each adapter, and the second rotating assembly can be assembled together first. Then, the second assembly part 82b and the first assembly part 82a can be assembled with the second mating part and the first mating part, respectively. Finally, the second assembly part 82b can be inserted into the second side wall 813, and the first assembly part 82a can be inserted into the first side wall 812, thus completing the assembly of the entire rotating shaft mechanism. The assembly method is simple, convenient, and easy to implement.

[0389] For example, the contours of the limiting groove 823 and the limiting portion 815 can be flared. Taking the limiting groove 823 as an example, the distance between the limiting groove 823 and its two side walls can gradually decrease from the end of the limiting groove 823 closer to the opening of the outer part 80 to the end of the limiting groove 823 farther from the opening (the end closer to the arc-shaped bottom wall 811). This facilitates the insertion of the limiting groove 823 into the protruding limiting portion 815 from the opening side, making assembly easier.

[0390] The structure and insertion method of the first assembly part 82a and the first side wall 812 can be referred to the second assembly part 82b and the second side wall 813, and will not be repeated here.

[0391] Of course, in some other examples, the first assembly part 82a and the first side wall 812, and the second assembly part 82b and the second side wall 813 can also be assembled together by means of bonding, snap-fit ​​connection, interference fit, etc.

[0392] In order for the appearance component to rotate relative to the first rotating component when the second rotating component rotates relative to the first rotating component, for example, at least one of the first adapter, second adapter, third adapter, fourth adapter, and fifth adapter may be provided with abutment portions at opposite ends along the rotation direction (the direction of rotation of the adapter).

[0393] See Figure 23As shown, the outer part 80 has a first abutting surface 816a and a second abutting surface 816b, which are located on opposite sides of the outer part 80 at one end of the opening. For example, the arc-shaped bottom wall 811, together with the first side wall 812 and the second side wall 813, forms an opening. The first abutting surface 816a and the second abutting surface 816b can be respectively located on the two end faces of the arc-shaped bottom wall 811 on the opening side. The two abutting portions of the aforementioned adapter can abut against the first abutting surface 816a and the second abutting surface 816b, respectively.

[0394] When the second rotating assembly 20 rotates relative to the first rotating assembly 10, the second rotating assembly 20 drives the first adapter 50a, the second adapter 50b, the third adapter 60a, the fourth adapter 60b, and the fifth adapter to rotate. The adapter with the abutting part can drive the appearance part 80 to rotate together through the abutting part, so that the appearance part 80 also rotates relative to the first rotating assembly.

[0395] Figure 24 for Figure 10 A cross-sectional schematic diagram of the central rotating shaft mechanism.

[0396] For example, see Figure 24 As shown, taking the second adapter 50b having an abutment portion as an example, the second adapter 50b can be provided with protruding abutment portions at both ends along its rotation direction, such as abutment portion 54a and abutment portion 54b respectively. The arc-shaped bottom wall 811 has a first abutment surface 816a and a second abutment surface 816b respectively on its two end faces located on the opening side. Abutment portion 54a can abut against the first abutment surface 816a, and abutment portion 54b can abut against the second abutment surface 816b.

[0397] When the rotating shaft mechanism 103 switches from the open state to the closed state, the second rotating component 20 rotates relative to the first rotating component 10 (as shown by the arrow in the figure), and the second adapter 50b also rotates relative to the first rotating component 10. The second adapter 50b drives the outer appearance component 80 to rotate together through the abutment part 54b.

[0398] Conversely, when the rotating shaft mechanism 103 switches from the closed state or intermediate state to the open state, the second rotating component 20 rotates in the opposite direction to the first rotating component 10, and the second adapter 50b can drive the outer appearance component 80 to rotate together through the abutment part 54a.

[0399] It should be noted that among the multiple adapters, such as the first adapter 50a, the second adapter 50b, the third adapter 60a, the fourth adapter 60b, and the fifth adapter, only some adapters may have abutment portions at both ends. Alternatively, abutment portions may be provided at both ends of each adapter. Or, in some examples, an abutment portion abutting against the first abutment surface 816a may be provided at one end of some adapters, and an abutment portion abutting against the second abutment surface 816b may be provided at the other end of some adapters.

[0400] In some examples, the torsion structure 40 may include an elastic element. When the elastic element is assembled with the first rotating assembly and the second rotating assembly, the elastic element may be in a state of elastic deformation. The elastic restoring force of the elastic element may act on the first rotating assembly, the second rotating assembly and the connecting part between them, pressing the structural parts of the rotating shaft mechanism to increase the friction.

[0401] Figure 25 for Figure 15 A magnified schematic diagram of a local structure in section C.

[0402] For example, see Figure 25 As shown, the torsion structure 40 may include a first elastic element 41, for example, the first elastic element 41 may be a spring. Of course, in some other examples, the first elastic element 41 may also be a disc spring assembly, an elastic gel component, etc. The torsion structure 40 may be located inside the outer appearance component 80, such as the torsion structure 40 may be located between the first friction component 12 and the second friction component 22. The first elastic element 41 may be compressed when assembled between the first friction component 12 and the second friction component 22, so that the elastic restoring force of the first elastic element can push the first friction component 12 and the second friction component 22, respectively squeezing the structural components on both sides of the first elastic element.

[0403] Of course, in some other examples, the torsion structure 40 can be arranged in other positions in the first rotating assembly and the second rotating assembly, such that the elastic restoring force of the first elastic member 41 of the torsion structure 40 can compress the mating parts, friction parts, and transition parts. For example, the torsion structure 40 can also be arranged between the first sidewall 812 of the appearance part 80 and the first mating part 111, between the second sidewall 813 of the appearance part 80 and the second mating part 113, between the third mating part 211 and the first friction member 12, etc.

[0404] For example, taking the torsion structure 40 located between the first friction member 12b and the second friction member 22b, the torsion structure 40 may further include a first mounting member 42 and a second mounting member 43, which are respectively located between the first friction member 12b and the second friction member 22b. For instance, the first mounting member 42 can be connected to the first friction member 12b, and the second mounting member 43 can be connected to the second friction member 22b. The two ends of the first elastic member 41 can be respectively disposed on the first mounting member 42 and the second mounting member 43 to realize the assembly of the first elastic member 41.

[0405] When the first elastic element 41 is assembled onto the first mounting member 42 and the second mounting member 43, the first elastic element 41 can be in a compressed state. The elastic restoring force of the first elastic element 41 can act on the first mounting member 42 and the second mounting member 43. In the first direction (y direction), the first mounting member 42 pushes a portion of the first friction element 12, a portion of the second friction element 22, the third mating part 211, the first mating part 111, and other structural components, as well as the connecting parts between the above structural components. The second mounting member 43 pushes a portion of the second friction element 22, a portion of the first friction element 12, the fourth mating part 213, the second mating part 113, and other structural components, as well as the connecting parts between the above structural components. This causes the structural components located on both sides of the torsion structure to be tightly pressed together, increasing the rotational friction of the first rotating assembly and the second rotating assembly, enabling the shaft mechanism to provide smooth torque.

[0406] It is understood that the first mating part 111, the second mating part 113, the third mating part 211, the fourth mating part 213, the first friction element 12, the second friction element 22, and various connecting parts are respectively arranged between the first side wall 812 and the second side wall 813. The first side wall 812 and the second side wall 813 play a limiting and constraining role on the above-mentioned structural components in the first direction (y direction), so that the rotating shaft mechanism can maintain the required torque and provide a smooth torque.

[0407] The first mounting member 42 is rotatably engaged with the first friction member 12b, and the second mounting member 43 is also rotatably engaged with the second friction member 22b, allowing the torsion structure 40 to rotate relative to the first friction member 12b and the second friction member 22b. The first mounting member 42 and the second mounting member 43 can be considered as a transition piece between the first friction member 12b and the second friction member 22b. When the second rotating assembly rotates, the second friction member 22b rotates relative to the first mounting member 42 and the second mounting member 43, which in turn drives the first mounting member 42 and the second mounting member 43 to rotate relative to the first friction member 12b. This increases the relative rotation trajectory of the first friction member 12b and the second friction member 22b, facilitating miniaturization while ensuring a large opening angle for the electronic device.

[0408] Figure 26 for Figure 10 A schematic diagram showing the disassembled torque structure, the first rotating component, and the second rotating component in the rotating shaft mechanism.

[0409] For example, see Figure 26 As shown, a fifth sliding structure 35a may be provided between the first mounting member 42 and the first friction member 12b, and a fifth sliding structure 35b may be provided between the second mounting member 43 and the second friction member 22b. The shapes and structures of the fifth sliding structures 35a and 35b may be the same.

[0410] The fifth sliding structure 35a may include a fifth arc-shaped slider 421 and a fifth arc-shaped groove 1201. For example, the first mounting member 42 may have a raised fifth arc-shaped slider 421 on the side facing the first friction member 12b, and the first friction member 12b may have a fifth arc-shaped groove 1201 on the side facing the first mounting member 42. The fifth arc-shaped slider 421 can be inserted into the fifth arc-shaped groove 1201 and slide along the fifth arc-shaped groove 1201, so that the first mounting member 42 and the first friction member 12b can be slidably connected through the fifth sliding structure 35a, and the first mounting member 42 and the first friction member 12b can rotate relative to each other.

[0411] The fifth sliding structure 35b may include a fifth arc-shaped slider 431 and a fifth arc-shaped groove 223. For example, the second mounting member 43 may have a raised fifth arc-shaped slider 421 on the side facing the second friction member 22b, and the second friction member 22b may have a fifth arc-shaped groove 223 on the side facing the second mounting member 43. The fifth arc-shaped slider 421 can be inserted into the fifth arc-shaped groove 223 and slide along the fifth arc-shaped groove 223, so that the second mounting member 43 and the second friction member 22b can be slidably connected through the fifth sliding structure 35b, and the second mounting member 43 and the second friction member 22b can rotate relative to each other. The rotation between the torsion structure and the first and second friction members is realized through the fifth sliding structure, which helps to increase the friction force of the rotation of the first and second rotating components and enhance the torque of the rotating shaft mechanism 103.

[0412] The fifth arc-shaped groove can have the same shape as the first arc-shaped groove, and the center of the fifth arc-shaped groove can coincide with the center of the first arc-shaped groove in the first direction (y direction), so that the rotation axis of the torsion structure 40 relative to the first friction member 12 and the second friction member 22 is consistent with the virtual axis.

[0413] For example, among the plurality of fifth adapters, the fifth adapter adjacent to the first mounting member 42 can be connected to the first mounting member 42, and the fifth adapter adjacent to the second mounting member 43 can be connected to the second mounting member 43. This allows the torsion structure 40 to rotate synchronously with the fifth adapters and other adapters, improving the opening and closing effect.

[0414] As Figure 26 Taking a fifth adapter 70b located between the second friction member 22a and the first friction member 12b, adjacent to the first mounting member 42, and a fifth adapter 70c located between the second friction member 22b and the first friction member 12c, adjacent to the second mounting member 43, as examples, the fifth adapter 70b can be inserted into the first mounting member 42, and the fifth adapter 70c can be inserted into the second mounting member 43.

[0415] For example, one of the fifth adapter 70b and the first mounting member 42 may have a raised sixth connector, while the other may have a sixth connector groove that mates with the sixth connector.

[0416] For example, the fifth adapter 70b has a raised sixth connector 75, and the first mounting member 42 has a sixth connector groove (not shown in the figure). The connection between the fifth adapter 70b and the first mounting member 42 is achieved through the insertion and engagement of the sixth connector 75 and the sixth connector groove. A sixth clearance groove 126 for avoiding the sixth connector 75 can be provided on the first friction member 12b.

[0417] For example, one of the fifth adapter 70c and the second mounting member 43 may have a raised seventh connector, while the other may have a seventh connector slot that mates with the seventh connector.

[0418] For example, the fifth adapter 70c has a raised seventh connector 76, and the second mounting member 43 has a seventh connector groove 432. The connection between the fifth adapter 70c and the second mounting member 43 is achieved through the insertion and engagement of the seventh connector 76 and the seventh connector groove 432. A seventh clearance groove 225 can be provided on the second friction member 22b to avoid the seventh connector 76.

[0419] To enable the assembly of the first elastic member 41, a protruding first fixing part 422 may be provided on the side of the first mounting member 42 facing the second mounting member 43. The first fixing part 422 may protrude and extend along the first direction (y direction), and one end of the first elastic member 41 may be arranged around the first fixing part 422.

[0420] The second mounting member 43 may have a protruding second fixing part 433 on the side facing the first mounting member 42. The second fixing part 433 may protrude and extend along the first direction (y direction). The other end of the first elastic member 41 may be arranged around the second fixing part 433.

[0421] The first fixing part 422 and the second fixing part 433 can have the same shape; for example, they can both be protruding columnar structures. The first fixing part 422 and the second fixing part 433 realize the assembly of the first elastic member 41 with the first mounting member 42 and the second mounting member 43. The assembly method is simple and has high stability.

[0422] The torsion structure 40 may also include a first guide rod 44 and a second guide rod 45. A first mounting hole 423 and a second mounting hole 424 may also be provided on the side of the first mounting member 42 facing the second mounting member 43. The first mounting hole 423 and the second mounting hole 424 may be located at opposite ends of the first mounting member 42, such as at opposite ends of the first mounting member 42 along the direction of rotation of the first mounting member 42.

[0423] The second mounting member 43 may have a third mounting hole and a fourth mounting hole (not shown in the figure) on the side facing the first mounting member 42. The third mounting hole and the fourth mounting hole may be located at opposite ends of the second mounting member 43. If they are located at opposite ends of the second mounting member 43 along the rotation direction, the arrangement can refer to the first mounting hole and the second mounting hole on the first mounting member 42.

[0424] The two ends of the first guide rod 44 can be inserted into the first mounting hole 423 and the third mounting hole respectively, so that the first mounting member 42 and the second mounting member 43 can move relative to the first guide rod 44 respectively. The two ends of the second guide rod 45 can be inserted into the second mounting hole 424 and the fourth mounting hole respectively, so that the first mounting member 42 and the second mounting member 43 can move relative to the second guide rod 45 respectively.

[0425] The extension directions of the first guide rod 44 and the second guide rod 45 are consistent with the first direction (y direction). The first guide rod 44 and the second guide rod 45 can guide and limit the movement of the first mounting member 42 and the second mounting member 43, ensuring that the first mounting member 42 and the second mounting member 43 move along the first direction (y direction) under the action of the first elastic member 41.

[0426] Understandably, the torsion structure 40 is located between the first friction member 12 and the second friction member 22, respectively pushing and compressing the structural components located on both sides of the torsion structure 40 in the first and second rotating assemblies. By adjusting the elastic compression degree of the first elastic member 41, such as further compressing or easing the compression degree, the compression degree of the torsion structure 40 on each structural component can be adjusted, thereby achieving the adjustment of the rotational friction between the first and second rotating assemblies, realizing the torque adjustment of the rotating shaft mechanism 103, and providing stable torque while meeting different design requirements.

[0427] For example, the degree of elastic compression of the first elastic element 41 when it is placed on the first friction element and the second friction element can be adjusted by changing the material, elastic capacity, length, etc. of the first elastic element 41.

[0428] Figure 26a for Figure 26 The simulated torque curves of a first and second friction components in a rotating shaft mechanism under the action of a torsion structure.

[0429] The torque curves between the first and second friction components in the aforementioned rotating shaft mechanism were obtained using simulation. (See [reference]) Figure 26a As shown, the pivot mechanism can provide stable torque to meet the torque requirements of electronic devices during opening and closing and for hovering effects.

[0430] Figure 27 This is a schematic diagram of another rotating shaft mechanism provided in an embodiment of this application. Figure 27 This illustration shows a schematic diagram of another rotating shaft mechanism provided in this application embodiment when it is in the open state.

[0431] Alternatively, in some examples, the torsion structure can be located outside the exterior component, such as... Figure 27 As shown, the torque structure 40 can cooperate with the first fixing member 11 or the second fixing member 21 located outside the outer appearance component 80. By pressing the first fixing member 11 or the second fixing member 21 in the first direction (y direction), it can compress the structural components in the first rotating assembly 10 and the second rotating assembly 20, ensuring the provision of stable torque. The torque structure 40 is arranged outside the outer appearance component 80, which reduces the size of the outer appearance component 80 while ensuring that the rotating shaft mechanism 103 can provide stable torque, thus improving the aesthetics and overall appearance of the electronic device when it is in the open state.

[0432] For example, the torsion structure 40 is used in conjunction with the first fixing member 11, such as the torsion structure 40 being used in conjunction with the second mounting part 114 of the first fixing member 11.

[0433] The torsion structure 40 may include a second elastic element 46, for example, the second elastic element 46 may be a disc spring assembly. Of course, in some other examples, the second elastic element 46 may be a spring, an elastic gel, etc. In the first direction (y direction), the torsion structure 40 may be located on the side of the second mounting portion 114 opposite to the first mounting portion 112.

[0434] For example, in the first direction (y direction), the third mating part 211 and the fourth mating part 213 are located between the first mating part 111 and the second mating part 113, and a plurality of first friction members 12 and a plurality of second friction members 22 are sequentially staggered and located between the third mating part 211 and the fourth mating part 213.

[0435] The first mating part 111 can be rotatably fitted with the third mating part 211 via the first adapter 50a and the second sliding structure (not shown in the figure). The third mating part 211 can be rotatably fitted with the first friction member 12a via the third adapter 60a and the third sliding structure (not shown in the figure). Adjacent first friction members 12 and second friction members 22 can be rotatably fitted with each other via the fifth adapter (such as the fifth adapter 70c) and the first sliding structure (not shown in the figure). The first friction member 12d can be rotatably fitted with the fourth mating part 213 via the fourth adapter 60b and the third sliding structure. The fourth mating part 213 can be rotatably fitted with the second mating part 113 via the second adapter 50b and the second sliding structure. Specific implementation details are provided above and will not be repeated here.

[0436] The elastic restoring force of the second elastic member 46 can push the second mounting portion 114 of the first fixing member 11, thereby squeezing the fourth mating portion 213, the first friction member 12, the second friction member 22, the third mating portion 211 and the first mating portion 111, as well as the connecting parts between the above-mentioned structural members, through the second mating portion 113 of the first fixing member 11, so that the above-mentioned structural members are tightly squeezed together, increasing the friction force during the rotation of the first rotating assembly 10 and the second rotating assembly 20, and ensuring that the rotating shaft mechanism 103 can provide a smooth torque.

[0437] For example, the rotating shaft mechanism 103 may include a support rod 90, which may be assembled with the first fixing member 11, and the second elastic member 46 may be disposed on the support rod 90.

[0438] Figure 28 for Figure 27 A schematic diagram showing the disassembled structure of the central rotating shaft mechanism.

[0439] See Figure 28 As shown, one end of the support rod 90 can be fixedly assembled with the first mounting part 112, and the other end of the support rod 90 can pass through the second mounting part 114 and the second elastic member 46. The extension direction of the support rod 90 can be consistent with the first direction (y direction).

[0440] Combination Figure 28 As shown, the second elastic member 46 is located on the side of the second mounting portion 114 facing away from the first mounting portion 112. The elastic restoring force of the second elastic member 46 can act on the second mounting portion 114, pushing the second mounting portion 114 toward the first mounting portion 112, squeezing the structural members located between the first mating portion 111 and the second mating portion 113, and providing stable torque.

[0441] The second mounting portion 114, the second elastic element 46, and the support rod 90 can be connected in a movable assembly manner. During assembly and torque adjustment, the second elastic element 46 can undergo elastic expansion and contraction deformation in the first direction (y direction) and act on the second mounting portion 114. This allows the second mounting portion 114 to move relative to the first mounting portion 112 along the support rod 90 to compress the structural components.

[0442] For example, a first through hole 1141 can be provided on the second mounting part 114, and a second through hole 461 can be provided on the second elastic member 46. The support rod 90 can be disposed through the first through hole 1141 and the second through hole 461, so that the support rod 90 is assembled with the first elastic member 41 and the second mounting part 114. There can be a gap between the support rod 90 and the first through hole 1141 and the second through hole 461, so that the second elastic member 46 and the second mounting part 114 can be movably sleeved on the support rod 90, and the second elastic member 46 and the second mounting part 114 can slide relative to the support rod 90 in the first direction (y direction).

[0443] The support rod 90 can also guide and limit the second mounting part 114 and the second elastic member 46, ensuring that the second mounting part 114 and the second mating part 113 move along the first direction (y direction) under the action of the second elastic member 46, so as to squeeze each structural member in the first direction (y direction).

[0444] The movable assembly of the second elastic element 46 with the support rod 90 allows the second elastic element 46 to slide along the support rod 90 under external force. By adjusting the position of the second elastic element 46 on the support rod 90, the degree of compression of each structural component by the second elastic element 46 and the second mating part 113 can be adjusted, thereby realizing the torque adjustment of the rotating shaft mechanism 103 and meeting different design requirements under the condition of providing stable torque.

[0445] For example, the torsion structure 40 may also include a first adjusting member 47, which is disposed on the support rod 90. In the first direction (y direction), the first adjusting member 47 may be located on the side of the second elastic member 46 facing away from the second mounting part 114. The first adjusting member 47 may limit the second elastic member 46, so that the second elastic member 46 is assembled between the first adjusting member 47 and the second mounting part 114.

[0446] The first adjusting member 47 can move along the support rod 90. By adjusting the position of the first adjusting member 47 on the support rod 90, the position of the second elastic member 46 can be adjusted, thereby adjusting the torque of the rotating shaft mechanism 103.

[0447] The first adjusting member 47 can be locked with the support rod 90. When the first adjusting member 47 is moved to a predetermined position, the first adjusting member 47 can be fixedly assembled with the support rod 90, limiting the position of the second elastic member 46, so that the rotating shaft mechanism 103 has a stable torque.

[0448] For example, the first adjusting member 47 may have a third through hole 471. The first adjusting member 47 is sleeved on the support rod 90 through the third through hole 471. The inner wall of the third through hole 471 may have internal threads. For example, the first adjusting member 47 may be a nut, bolt or other structure.

[0449] The outer wall of the support rod 90 may have external threads, and the internal thread of the third through hole 471 and the external thread of the support rod 90 can achieve threaded engagement. Applying external force to rotate the first adjusting member 47 causes the first adjusting member 47 to rotate relative to the support rod 90 while sliding along the support rod 90, thereby adjusting the position of the first adjusting member 47 on the support rod 90 and realizing the torque adjustment of the rotating shaft mechanism 103.

[0450] Without external force, the threaded engagement of the internal and external threads prevents the first adjusting member 47 from sliding relative to the support rod 90. The position of the first adjusting member 47 on the support rod 90 is fixed, thus limiting and fixing the first adjusting member 47, enabling the rotating shaft mechanism 103 to provide smooth torque.

[0451] For example, the first mounting portion 112 and the second mounting portion 114 of the first fixing member 11 can be assembled together, which helps to further improve the torsional stability of the rotating shaft mechanism 103. Furthermore, when assembling with the first housing of the electronic device, assembling one of the first mounting portion 112 and the second mounting portion 114 with the first housing can realize the assembly of the first fixing member 11 with the first housing, which facilitates the assembly process.

[0452] For example, in the example where the torsion structure 40 cooperates with the second mounting part 114, the first mounting part 112 can be assembled and connected with the first housing, thereby enabling the first fastener 11 to be assembled with the first housing.

[0453] It should be noted that the second mounting part 114 and the first mounting part 112 are assembled in a movable and adjustable manner, ensuring that during assembly or torque adjustment, the second mounting part 114 and the first mounting part 112 can move relative to each other along the first direction (y direction) to press against the structural components between the second mating part 113 and the first mating part 111. After the rotating shaft mechanism 103 is assembled or the torque is adjusted, the first mounting part 112 and the second mounting part 114 can be stably assembled together, providing a limiting constraint on the structural components located between the first mating part 111 and the second mating part 113, so that the rotating shaft mechanism 103 can maintain the required torque and provide a smooth torque.

[0454] For example, the first mounting portion 112 may include a first segment 119 and a first extension portion 115. The first mating portion 111 and the first connecting rod 13 are respectively connected to the first segment 119, and the support rod 90 can be fixed to the first segment 119. One end of the first extension portion 115 can be fixed to the first segment 119, and the other end of the first extension portion 115 can extend towards the second mounting portion 114 along a first direction (y direction), so that the first extension portion 115 and the second mounting portion 114 at least partially overlap (at least partially overlap in the direction perpendicular to the first mounting portion 112). The second mounting portion 114 is sleeved on the support rod 90, and a portion of the second mounting portion 114 is located between the support rod 90 and the extension portion 115.

[0455] A first through hole 1151 may be provided on the first extension portion 115, and a first fixing hole (not shown in the figure) may be provided on the second mounting portion 114. The rotating shaft mechanism 103 may also include a first mounting part 116. One end of the first mounting part 116 may abut against the first extension portion 115, and the other end of the first mounting part 116 may pass through the first through hole 1151 and cooperate with the first fixing hole.

[0456] The first assembly 116 and the first fixing hole are detachably fitted. For example, the first assembly 116 can be a screw, bolt or other structural component. The other end of the first assembly 116 can have an external thread, and the first fixing hole can be a threaded hole with an internal thread on its inner wall. The detachable assembly of the first assembly 116 and the first fixing hole is achieved through the threaded fit.

[0457] The first through hole 1151 can be a smooth hole without threads on its inner wall. The first through hole 1151 can have a certain extension length in the first direction (y direction), such as the shape of the first through hole 1151 being a racetrack-like circle.

[0458] The extension length of the first through hole 1151 in the first direction (y direction) can be greater than the outer diameter of the first mounting part 116 in the first direction. In the first direction, the position of the first mounting part 116 in the first through hole 1151 can be adjusted to meet the movable adjustment requirements of the first mounting part 112 and the second mounting part 114.

[0459] During assembly or torque adjustment, the first mounting part 116 can be separated from the first fixing hole. Removing the first mounting part 116 allows the first mounting portion 112 and the second mounting portion 114 to move relative to each other in the first direction (y-direction), thereby pressing the structural components to achieve the required torque. After assembly or torque adjustment, one end of the first mounting part 116 passes through the first through hole 1151, and the other end of the first mounting part 116 is assembled with the first fixing hole, achieving stable assembly of the first mounting portion 112 and the second mounting portion 114, allowing the rotating shaft mechanism to maintain a stable torque.

[0460] In some examples, a third guide rod 117 may also be provided on the first mounting portion 112, extending along the first direction (y-direction). An insertion hole (not shown in the figure) may also be provided on the second mounting portion 114, into which the third guide rod 117 can be inserted, further improving the assembly stability of the first mounting portion 112 and the second mounting portion 114. The third guide rod 117 can act as a guide and limiter, ensuring that the second mounting portion 114 moves relative to the first mounting portion 112 along the first direction (y-direction) to compress the structural components.

[0461] For example, the third mounting portion 212 and the fourth mounting portion 214 of the second fixing member 21 can also be assembled together to further improve the stability of the rotating shaft mechanism 103. When assembling with the second housing of the electronic device, assembling one of the third mounting portion 212 and the fourth mounting portion 214 with the second housing facilitates the assembly of the second fixing member 21 with the second housing. In the example where the torsion structure 40 cooperates with the second mounting portion 114, the third mounting portion 212 can be assembled with the second housing, thus enabling the second fixing member 21 to be assembled with the second housing.

[0462] The third mounting part 212 and the fourth mounting part 214 are assembled in a movable and adjustable manner, ensuring that during assembly or torque adjustment, the fourth mounting part 214 can move relative to the third mounting part 212 along the first direction (y direction) to press the structural components between the third mating part 211 and the fourth mating part 213. After assembly or torque adjustment, the third mounting part 212 and the fourth mounting part 214 can be stably assembled together, better maintaining torque and enabling the rotating shaft mechanism to provide smooth torque.

[0463] For example, the third mounting portion 212 may include a second portion 212a and a second extension portion 212b. The third mating portion 211 and the second connecting rod 23 may be connected to the second portion 212a. One end of the second extension portion 212b is connected to the second portion 212a, and the other end of the second extension portion 212b extends toward the fourth mounting portion 214 along a first direction (y direction), so that the second extension portion 115 and the fourth mounting portion 214 at least partially overlap (in the direction perpendicular to the third mounting portion 212).

[0464] In some examples, a receiving groove 218 may be provided on one side of the second extension 212b, at least a portion of the fourth mounting portion 214 may be located in the receiving groove 218, and the fourth mounting portion 214 may move in the receiving groove 218 along the first direction (y direction).

[0465] A second through hole 215 may be provided on the second extension portion 115, and a second fixing hole 217 may be provided on the fourth mounting portion 214. The rotating shaft mechanism 103 may also include a second mounting component 216. One end of the second mounting component 216 may abut against the second extension portion 212b, and the other end of the second mounting component 216 may pass through the second through hole 215 and be fixed in place with the second fixing hole 217.

[0466] The second assembly 216 and the second fixing hole 217 are detachably fitted. For example, the second assembly 216 can be a screw, bolt, or other structural component. The other end of the second assembly 216 may have external threads, and the second fixing hole 217 can be a threaded hole with internal threads on its inner wall. The detachable assembly of the second assembly 216 and the second fixing hole 217 is achieved through this threaded fit.

[0467] The second through hole 215 can be a smooth hole without threads on its inner wall. The second through hole 215 can have a certain extension length in the first direction (y direction), such as the shape of the second through hole 215 being a racetrack-like circle.

[0468] The extension length of the second through hole 215 in the first direction is greater than the outer diameter of the second mounting part 216 in the first direction, so that the position of the second mounting part 216 in the second through hole 215 along the first direction can be adjusted to meet the movable adjustment requirements of the third mounting part 212 and the fourth mounting part 214.

[0469] During assembly or torque adjustment, the second mounting part 216 can be removed, and the third mounting part 212 and the fourth mounting part 214 can move relative to each other in the first direction (y direction) to compress the structural components and achieve the required torque. After assembly or torque adjustment, one end of the second mounting part 216 passes through the second through hole 215, and the other end of the second mounting part 216 is assembled with the second fixing hole 217, thereby achieving stable assembly of the third mounting part 212 and the fourth mounting part 214, allowing the rotating shaft mechanism to maintain a stable torque.

[0470] To further simplify the structure of the exterior component 80, the exterior component 80 may include a second housing portion 83, a third assembly portion 84a and a fourth assembly portion 84b. The structure of the second housing portion 83 may be the same as that of the first housing portion 81 described above, and may include a first side wall 832, an arc-shaped bottom wall 831 and a second side wall 833.

[0471] A third assembly part 84a may be provided on the first sidewall 832, and a fourth assembly part 84b may be provided on the second sidewall 833. The third assembly part 84a and the first sidewall 812 may be connected together by means of bonding, welding, snap-fitting, etc., and the fourth assembly part 84b and the second sidewall 813 may also be connected together by means of bonding, welding, snap-fitting, etc.

[0472] The third assembly part 84a can be fixed at one end to the first side wall 832, and the other end can extend away from the first side wall 832 along the first direction (y direction). The fourth assembly part 84b can be fixed at one end to the second side wall 833, and the other end can extend away from the second side wall 833 along the first direction (y direction).

[0473] At least a portion of the first rotating assembly and the second rotating assembly can be located between the arcuate bottom wall 831 of the second assembly part 82b and the second housing part 83, thereby assembling the exterior part 80 with the first rotating assembly and the second rotating assembly. The structural design of the second assembly part 82b is simpler, making it easier to process and assemble the exterior part 80.

[0474] For example, the sides of the third assembly part 84a and the fourth assembly part 84b facing the arc-shaped bottom wall 831 can be arc-shaped surfaces, and the gap between the third assembly part 84a and the arc-shaped bottom wall 831 can form an arc-shaped space. At least the first mating part 111 can be located between the third assembly part 84a and the arc-shaped bottom wall 831. The outer contour shape of the first mating part 111 can also be arc-shaped, so that the first mating part 111 can slide within the arc-shaped space, realizing the rotational engagement between the first mating part 111 and the outer appearance part 80.

[0475] Correspondingly, the gap between the fourth assembly part 84b and the arc-shaped bottom wall 831 can also form an arc-shaped space. At least the second mating part 113 can be located between the fourth assembly part 84b and the arc-shaped bottom wall 831, so that the second mating part 113 can rotate with the appearance part 80, which means that the appearance part 80 and the first rotating assembly can rotate relative to each other.

[0476] Figure 29 for Figure 27 A cross-sectional schematic diagram of the rotating shaft mechanism.

[0477] In this embodiment, at least one of the first adapter 50a, the second adapter 50b, and the third adapter 60a may have abutment portions at both ends along the rotation direction, for example, see [reference needed]. Figure 29 As shown, taking the second adapter 50b as an example, the second adapter 50b has abutment portions 54a and 54b respectively provided on both ends along its rotation direction. A first abutment surface 831a and a second abutment surface 831b can be respectively provided on the two end faces of the arc-shaped bottom wall 831 located on the opening side (see reference). Figure 28 (As shown).

[0478] See also Figure 29 As shown, the abutting part 54a can abut against the first abutting surface 831a, and the abutting part 54b can abut against the second abutting surface 831b. When the second rotating assembly 20 rotates relative to the first rotating assembly 10, the second rotating assembly 20 drives the second adapter 50b to rotate, and the second adapter 50b drives the outer appearance part 80 to rotate together through the two abutting parts.

[0479] Figure 30 for Figure 27 Assembly diagram of the central rotating shaft mechanism and the flexible circuit board.

[0480] In examples where the electronic device is a laptop computer, the device may also include a flexible circuit board with both ends located within a first housing and a second housing to meet the communication requirements between the display and the system. A portion of the flexible circuit board is mounted on a hinge mechanism and undergoes bending or flattening deformation as the hinge mechanism rotates.

[0481] For example, see Figure 30 As shown, the first fastener 11 may include a first inner surface 11a, and the second fastener 21 may include a second inner surface 21a.

[0482] The first fastener 11 may also include a first outer surface 11b (see reference). Figure 33 As shown, the first inner side 11a and the first outer side 11b of the first fastener 11 are opposite each other, such that the first inner side 11a and the first outer side 11b can be opposite each other in the thickness direction (z direction).

[0483] When the rotating shaft mechanism 103 is assembled onto the electronic device, the first fixing member 11 can be located in the assembly cavity at the edge of the first housing, the first outer side 11b can be disposed closer to the first surface of the main body of the first housing, and the first inner side 11a can be disposed further away from the first surface of the main body.

[0484] The second fastener 21 may also include a second outer surface 21b, see further. Figure 30 As shown, the first inner surface 11a and the second inner surface 21a can be located on the same side of the rotating shaft mechanism 103, and the first outer surface, the outer appearance part 80, and the second outer surface can be located on the same side of the rotating shaft mechanism 103. When the rotating shaft mechanism 103 is in the closed state, the side containing the first inner surface 11a and the second inner surface 21a can be located inside the rotating shaft mechanism 103, and the side containing the first outer surface and the second outer surface can be located outside the rotating shaft mechanism 103. The first inner surface 11a and the second inner surface 21a are adjacent and opposite to each other, while the first outer surface and the second outer surface are opposite to each other.

[0485] The rotating shaft mechanism 103 includes a rotating region 103a, which can be the area where the first rotating component 10 and the second rotating component 20 have a relative sliding fit. Each structural component in the rotating shaft mechanism 103 that has a sliding fit through a sliding structure can be located within the rotating region 103a. For example, the position of the rotating region 103a corresponds to the distribution positions of the first mating part 111, the third mating part 211, the first friction member 12, the second friction member 22, the fourth mating part 213, and the second mating part 113.

[0486] A portion of the flexible circuit board 105 can be fixed to the first outer side of the first fixing member 11. Another portion of the flexible circuit board 105 can be attached to the rotating shaft mechanism 103, extending from the first outer side of the first fixing member 11 and the first inner side 11a of the first fixing member 11 to the second inner side 21a of the second fixing member 21, and then fixed thereon. The flexible circuit board 105 spans the rotation area 103a of the rotating shaft mechanism 103.

[0487] When the rotating shaft mechanism 103 is in the open state, a portion of the flexible circuit board 105 located in the rotating area 103a of the rotating shaft mechanism 103 is laid flat on the side of the rotating shaft mechanism 103 facing away from the outer appearance component 80 (i.e., the inner side of the rotating shaft mechanism 103), and the flexible circuit board 105 is in a flattened state.

[0488] When the rotating shaft mechanism 103 switches from the open state to the closed state (or an intermediate state), the second rotating component 20 rotates relative to the first rotating component 10 (as shown by the arrow in the figure), and a portion of the flexible circuit board 105 located in the rotating area 103a of the rotating shaft mechanism 103 is bent. When the rotating shaft mechanism 103 is in the closed state, a portion of the flexible circuit board 105 located in the rotating area 103a is in a bent state (see figure). Figure 32 (As shown).

[0489] It should be noted that in any of the above examples, the rotating shaft mechanism can be assembled with the flexible circuit board. For example, in the example where the torsion structure 40 is located inside the outer part 80, the flexible circuit board can also be assembled on the rotating shaft mechanism 103. The specific assembly position of the flexible circuit board, the way the flexible circuit board bends or unfolds with the rotation of the rotating shaft mechanism, etc., can be referred to the assembly of the flexible circuit board and the rotating shaft mechanism in this example.

[0490] It is understandable that when the rotating mechanism 103 is in the closed state, the portion of the flexible circuit board 105 located in the rotation area 103a is in a bent state, and the length of this portion of the flexible circuit board 105 in the extension direction of the rotation area 103a is relatively long. When the rotating mechanism 103 is in the open state, the portion of the flexible circuit board 105 located in the rotation area 103a is laid flat, and the length of this portion of the flexible circuit board 105 in the extension direction of the rotation area 103a becomes smaller. This results in redundancy of the flexible circuit board 105 in other locations of the rotating mechanism 103 or other locations within the electronic device.

[0491] To avoid redundancy in the flexible circuit board 105, see, for example, further details. Figure 30 As shown, the rotating shaft mechanism 103 may further include an adjustment structure 110, which may include a sliding block 1101. At least a portion of the sliding block 1101 is located on the side of the first fixing member 11 facing away from the second fixing member 21, and a portion of the flexible circuit board 105 is located on the side of the sliding block 1101 facing away from the first mounting portion 112. The sliding block 1101 can slide relative to the first fixing member 11, such as sliding the sliding block 1101 towards or away from the first fixing member 11 along the width direction (x direction).

[0492] Figure 31 This is a schematic diagram of the assembly of another rotating shaft mechanism with a flexible circuit board when it is in the closed state, as provided in an embodiment of this application.

[0493] See Figure 31 As shown, when the rotating shaft mechanism 103 is in the closed state, part of the flexible circuit board 105 in the rotating area 103a is in a bent state, and in the width direction, the sliding block 1101 is close to the first fixing member 11.

[0494] When the rotating shaft mechanism 103 switches from the closed state to the open state (or intermediate state), the second fixing member 21 rotates relative to the first fixing member 11, such as... Figure 31 As indicated by the arrow, a portion of the flexible circuit board 105 within the rotation zone 103a unfolds as the second fixing member 21 rotates, and the length of the portion of the flexible circuit board 105 within the rotation zone 103a decreases in the extending direction. The sliding block 1101 can move away from the first fixing member 11 along the width direction, increasing the distance between the sliding block 1101 and the first fixing member 11, thereby increasing the length of the flexible circuit board 105 that can be supported by the first fixing member 11 and the sliding block 1101, achieving the effect of absorbing the redundancy of the flexible circuit board 105.

[0495] Figure 32 for Figure 31 A schematic diagram of the assembly of the central rotating shaft mechanism with the flexible circuit board when the mechanism is in the open state.

[0496] When the rotating shaft mechanism 103 is in the open state, see Figure 32 As shown, the distance between the sliding block 1101 and the first fixing member 11 is relatively large in the width direction (x direction). This ensures that when the rotating shaft mechanism 103 is in the open state, a portion of the flexible circuit board 105 in the rotating area 103a unfolds and lays flat, exhibiting good flatness. This reduces or avoids problems such as damage to the flexible circuit board 105 caused by redundancy.

[0497] Correspondingly, when the rotating shaft mechanism 103 switches from the open state to the closed state (or intermediate state), the sliding block 1101 can move towards the first fixing member 11 along the width direction, shortening the distance between the sliding block 1101 and the first fixing member 11, thereby making the length of part of the flexible circuit board 105 in the rotating area 103a longer and bend.

[0498] It should be noted that the rotating shaft mechanism 103 in any of the examples above may include an adjustment structure 110, which is used to adjust the flexible circuit board 105 and avoid redundancy in the flexible circuit board 105. For example, in the example above where the torsion structure 40 is located inside the outer part 80, the rotating shaft mechanism 103 may also include an adjustment structure 110. The structural implementation of the adjustment structure 110, the assembly method of the adjustment structure 110 in the rotating shaft mechanism 103, and the cooperation method between the adjustment structure 110 and the flexible circuit board 105 can all refer to this example.

[0499] Figure 33 for Figure 27 A schematic diagram of the structure of the central rotating shaft mechanism and the flexible circuit board assembly from another perspective.

[0500] To achieve the assembly of the sliding block 1101 and the first fixing member 11. For example, see... Figure 33 As shown, the adjustment structure 110 also includes a fixing block 1102, which is disposed on the first outer side 11b of the first fixing member 11. For example, the fixing block 1102 can be fixed to the first fixing member 11 by means of bonding, threaded connection, snap-fit ​​connection, etc.

[0501] The fixing block 1102 can be fixed to at least one of the first mounting portion 112 and the second mounting portion 114 of the first fixing member 11. For example, the fixing block 1102 can be connected to the first mounting portion 112 and the second mounting portion 114 respectively.

[0502] Figure 34 for Figure 31 A partial cross-sectional structural diagram of the central pivot mechanism.

[0503] See Figure 34As shown, a portion of the sliding block 1101 can be located on the first outer side 11b of the first fixing member 11 and can slidably engage with the fixing block 1102. A portion of the sliding block 1101 can be located on the side of the first fixing member 11 facing away from the second fixing member 21. A portion of the flexible circuit board 105 located on the first outer side 11b of the first fixing member 11 can be fixed to the fixing block 1102. The portion of the flexible circuit board 105 is attached to the side of the sliding block 1101 facing away from the first fixing member 11, and the first inner side 11a of the first fixing member 11 extends to the second inner side 21a of the second fixing member 21.

[0504] For example, the adjustment structure 110 may also include a first fixing plate 1103 and a second fixing plate 1104 (in combination). Figure 33 As shown, the first fixing plate 1103 and the second fixing plate 1104 can be stacked and fixed on the fixing block 1102, and part of the flexible circuit board 105 can be located between the first fixing plate 1103 and the second fixing plate 1104.

[0505] See also Figure 34 As shown, the adjustment structure 110 also includes a third elastic element 1105, which is disposed between the sliding block 1101 and the fixed block 1102.

[0506] When the rotating shaft mechanism 103 is in the closed state, part of the flexible circuit board 105 in the rotating area is in a bent state and is relatively long. The flexible circuit board 105 can pull the sliding block 1101. In the width direction, the distance between the sliding block 1101 and the first fixing member 11 is relatively short, and the third elastic member 1105 is compressed.

[0507] When the rotating shaft mechanism 103 switches from the closed state to the open state (intermediate state), the second fixing member 21 rotates relative to the first fixing member 11. A portion of the flexible circuit board 105 within the rotating area unfolds and its length decreases as the second fixing member 21 rotates. Under the elastic recovery action of the third elastic member 1105, the sliding block 1101 can move away from the first fixing member 11 along the width direction, achieving the effect of absorbing redundancy.

[0508] Correspondingly, when the rotating shaft mechanism 103 switches from the open state to the closed state (intermediate state), part of the flexible circuit board 105 in the rotating area bends as it rotates, and its length increases, thereby pulling the sliding block 1101 to move towards the first fixing member 11 in the width direction, reducing the distance between the sliding block 1101 and the first fixing member 11, and compressing the third elastic member 1105.

[0509] Figure 35 for Figure 31 A schematic diagram of the assembly of the sliding block and the fixed block in the rotating shaft mechanism. Figure 36 for Figure 35A schematic diagram of the split structure of the sliding block and the fixed block.

[0510] See Figure 35 As shown, to ensure relative sliding between the sliding block 1101 and the fixed block 1102, a guide groove 1102a can be provided on the fixed block 1102, combined with... Figure 36 As shown, the sliding block 1101 may have a protruding sliding member 1101a, which can be inserted into the guide groove 1102a and slide along the guide groove 1102a.

[0511] The extension direction of the guide groove 1102a can be consistent with the width direction. The guide groove 1102a plays a guiding and limiting role, so that the sliding block 1101 slides only in the width direction toward or away from the fixed block 1102 (first fixed member 11), thereby improving the smoothness of the relative sliding of the sliding block 1101 and the fixed block 1102.

[0512] For example, the sliding block 1101 may include a first portion 1101b, a transition portion 1101c, and a second portion 1101d connected in sequence. The first portion 1101b can be slidably connected to the fixing block 1102, and the sliding member 1101a can be disposed on the first portion 1101b. The second portion 1101d can extend to the side of the first fixing member 11 opposite to the second fixing member 21. The outer contour shape of the transition portion 1101c can be arc-shaped to avoid damage to the flexible circuit board 105.

[0513] The fixing block 1102 may include a base plate 1102b, a first fixing body 1102c and a second fixing body 1102d. The first fixing body 1102c and the second fixing body 1102d may be disposed on one side of the base plate 1102b and located on opposite sides of one side of the base plate 1102b, respectively. There is an accommodating gap between the first fixing body 1102c and the second fixing body 1102d.

[0514] Guide rail grooves 1102a can be respectively opened on the opposite sides of the first fixing member 11 and the second fixing member 21, and protruding sliding members 1101a are respectively provided on the opposite sides of the first part 1101b of the sliding block 1101.

[0515] At least a portion of the third elastic element 1105 can be accommodated in the receiving gap between the first fixed body 1102c and the second fixed body 1102d. A mounting plate 1102e can also be provided on the base plate 1102b, extending into the receiving gap. One end of the third elastic element 1105 can be disposed on the mounting plate 1102e. The other end of the third elastic element 1105 can be disposed on the transition portion 1101c of the sliding block 1101. This arrangement of the fixed block 1102, the sliding block 1101, and the third elastic element 1105 is compact, facilitating the miniaturization of the rotating shaft mechanism 103.

[0516] The two ends of the first fixing plate 1103 and the second fixing plate 1104 can be respectively disposed on the first fixing body 1102c and the second fixing body 1102d. For example, see Figure 36 As shown, mounting grooves 1102g can be respectively opened on opposite sides of the first fixing body 1102c and the second fixing body 1102d, and the two ends of the first fixing plate 1103 can be respectively set in the mounting groove.

[0517] A fourth mounting hole 1102h can be provided on the first fixing body 1102c and the second fixing body 1102d respectively, and a fifth mounting hole (not shown in the figure) can be provided on the second fixing plate 1104. The two ends of the second fixing plate 1104 can be fixed on the first fixing body 1102c and the second fixing body 1102d by screws, bolts and other fittings.

[0518] It should be noted that the aforementioned hinge mechanism 103 can be applied to both laptop computers and other electronic devices such as tablet computers with stands. In the example of a tablet computer with a stand, the hinge mechanism enables the opening and closing of the stand and the device body. There is usually no communication requirement between the stand and the device body. Therefore, the hinge mechanism 103 may not include the aforementioned adjustment structure 110. The hinge mechanism 103 may include the aforementioned first rotating component, second rotating component, outer part, first adapter, second adapter, third adapter, fourth adapter, and fifth adapter.

[0519] Figure 37 This is a schematic diagram of another rotating shaft mechanism provided in an embodiment of this application. Figure 37 This illustration shows a structural diagram of another rotating shaft mechanism provided in the present application when it is in the open state.

[0520] In another embodiment of the present application, the hinge mechanism 103 is further simplified in structure, such as making it more suitable for use in electronic devices with simpler structural designs, such as tablet computers with stands, or in other electronic devices with higher requirements for miniaturization of the hinge mechanism 103. The hinge mechanism 103 may not include structures such as the outer appearance component, the first adapter, the second adapter, the third adapter, the fourth adapter, and the fifth adapter.

[0521] For example, see Figure 37As shown, the rotating shaft mechanism 103 includes a first rotating assembly 10 and a second rotating assembly 20. The first rotating assembly 10 may include a first fixing member 11 and a plurality of first friction members 12. The first fixing member 11 and the plurality of first friction members 12 are connected together. For example, the first mounting portion 112 and the second mounting portion 114 of the first fixing member 11 can be connected to the plurality of first friction members 12 by a first connecting rod 13 (see reference). Figure 38 As shown in the figure, the specific implementation method can be referred to the above text, and will not be repeated here.

[0522] In some examples, see further. Figure 37 As shown, the first fixing member 11 can form a receiving chamber 11c, and the first friction member 12 can be located on one side of the receiving chamber 11c. When the rotating shaft mechanism 103 is in the closed state, at least part of the second rotating component 20 can also be located in the receiving chamber 11c, so that the thickness of the rotating shaft mechanism 103 is significantly reduced when it is in the closed state.

[0523] The second rotating assembly 20 may include a second fixing member 21 and a plurality of second friction members 22, the second fixing member 21 and the plurality of second friction members 22 being connected together. For example, the second fixed third mounting portion 212 and fourth mounting portion 214 may be connected to the plurality of second friction members 22 by a second connecting rod 23 (see reference). Figure 38 As shown in the figure, the specific implementation method can be referred to the above text, and will not be repeated here.

[0524] Taking the rotating mechanism 103 assembled on a tablet computer with a stand as an example, the first rotating component 10 is assembled with one of the first housing of the device body and the second housing of the stand, and the second rotating component 20 is assembled with the other one. For example, the first rotating component 10 is assembled with the first housing, and the second rotating component 20 is assembled with the second housing.

[0525] For example, see continue. Figure 37 As shown, the first fastener 11 can be assembled with the first housing, such as by means of threaded connection, riveting, bonding, snap-fit ​​connection, etc. The second fastener 21 can be connected with the second housing, such as by means of threaded connection, riveting, bonding, snap-fit ​​connection, etc.

[0526] Multiple first friction elements 12 and multiple second friction elements 22 can be staggered along a first direction (y direction), and adjacent first friction elements 12 and second friction elements 22 have a first sliding structure 31. Taking two adjacent first friction elements and second friction elements as an example, the first sliding structure 31 includes a first arc-shaped groove 224 and a first arc-shaped slider 127 that are in sliding engagement.

[0527] When the second rotating assembly 20 rotates relative to the first rotating assembly 10, the first friction element 12 and the second friction element 22 rotate relative to each other, and the first arc-shaped slider 127 slides along the first arc-shaped groove 224. This causes the first rotating assembly 10 and the second rotating assembly 20 to rotate relative to each other around a virtual axis, reducing the space occupied by the rotating shaft mechanism 103 and improving the flexibility of the rotating shaft mechanism 103 in the assembly position of the electronic device. For example, the virtual axis of the rotating shaft mechanism 103 can be located at the joint between the first housing and the second housing, making the joint between the first housing and the second housing smaller, and the width of the joint does not change much during the rotation of the first housing and the second housing. During the opening and closing of the bracket, the second housing of the bracket does not rise significantly relative to the first housing in the thickness direction, and when the bracket is in the open state, the separation between the first housing and the second housing is small, improving the aesthetics and overall integrity of the electronic device.

[0528] The first rotating component 10 and the second rotating component 20 rotate relative to each other around a virtual axis, thereby causing the first housing and the second housing to rotate around the virtual axis, thus realizing the opening and closing of the bracket and the main body of the equipment.

[0529] The first rotating assembly 10 and the second rotating assembly 20 can be unfolded relative to each other, so that the rotating shaft mechanism 103 is in the open state. For example... Figure 37 As shown, when the rotating shaft mechanism 103 is in the open state, the first rotating component 10 and the second rotating component 20 cannot continue to rotate. For example, the rotating shaft mechanism may include a stop structure (see below) to restrict the continued rotation of the first rotating component 10 and the second rotating component 20. At this time, the included angle between the first rotating component 10 and the second rotating component 20 can be approximately 90°. The included angle between the second housing 102 and the first housing 101 can also be approximately 90°, and the bracket is open relative to the main body of the device, at which time the electronic device is in the open state.

[0530] The first rotating component 10 and the second rotating component 20 can rotate relative to each other to an intermediate state, so that the rotating shaft mechanism 103 is in an intermediate state. For example, when the rotating shaft mechanism 103 is in an intermediate state, the included angle between the first rotating component 10 and the second rotating component 20 can be greater than 0° and less than 90°. At this time, the electronic device is also in an intermediate state.

[0531] Figure 38 for Figure 37 A schematic diagram of the central shaft mechanism in the closed state.

[0532] See Figure 38As shown, the first rotating assembly 10 and the second rotating assembly 20 can be folded relative to each other to a closed state. The first rotating assembly 10 and the second rotating assembly 20 can be brought together until they are parallel to each other, and the included angle between the first rotating assembly 10 and the second rotating assembly 20 can be approximately 0°. At this time, the rotating shaft mechanism 103 is in a closed state. The second housing and the first housing can also be parallel to each other, and the included angle between them is approximately 0°. The bracket is closed relative to the main body of the device, and at this time, the electronic device is in a closed state.

[0533] The arrangement of the first fixing member 11, the second fixing member 21, the first friction member 12, and the second friction member 22 can be varied, as detailed above. For example, the first fixing member 11 includes a first mating portion 111 and a second mating portion 113, and the second fixing member 21 includes a third mating portion 211 and a fourth mating portion 213. The third mating portion 211 and the fourth mating portion 213 can be located between the first mating portion 111 and the second mating portion 113, and the first friction member 12 and the second friction member 22 can be located between the third mating portion 211 and the fourth mating portion 213, respectively.

[0534] Adjacent first friction members 12 and second friction members 22 are rotated together via a first sliding structure. First fixing members 11 and second fixing members 21 can also be rotated together; for example, first mating part 111 and third mating part 211 can be rotated together via a second sliding structure, and fourth mating part 213 and second mating part 113 can also be rotated together via a second sliding structure. One of the first friction members 12 adjacent to the third mating part and the third mating part 211 can be rotated together via a third sliding structure, and the other first friction member 12 adjacent to the fourth mating part can be slidably fitted with the fourth mating part 213. The structure and effects of the first sliding structure, second sliding structure, and third sliding structure are described above and will not be repeated here.

[0535] For example, there may be only one first sliding structure between adjacent first friction member 12 and second friction member 22, and no adapter (such as the fifth adapter mentioned above) is provided between the first friction member 12 and the second friction member 22. The first friction member 12 and the second friction member 22 can directly contact each other to achieve rotational engagement, which simplifies the structure of the rotating shaft mechanism 103 and helps to achieve miniaturization and low cost of the rotating shaft mechanism 103.

[0536] Figure 39 for Figure 38 A schematic diagram of the disassembled structure of the central rotating shaft mechanism.

[0537] For example, see Figure 39As shown, taking the first friction member 12a and the second friction member 22a as examples, the surface of the first friction member 12a facing the second friction member 22a may have a raised first arc-shaped slider 127, and the surface of the second friction member 22a facing the first friction member 12a may have a first arc-shaped groove 224. The first arc-shaped slider 127 can be inserted into the first arc-shaped groove 224 and slide along the first arc-shaped groove 224. The first arc-shaped groove 224 and the first arc-shaped slider 127 can form a first sliding structure 31 to realize the rotational engagement of the first friction member 12a and the second friction member 22a.

[0538] Correspondingly, there may be only one second sliding structure 321 between the first mating part 111 and the third mating part 211, and there may be only one second sliding structure 322 between the fourth mating part 213 and the second mating part 113. No adapter (such as the first adapter and the second adapter mentioned above) is provided between the first mating part 111 and the third mating part 211, or between the fourth mating part 213 and the second mating part 113. The first mating part 111 and the third mating part 211 can directly rotate into contact, and the fourth mating part 213 and the second mating part 113 can also directly rotate into contact, further simplifying the structural design of the rotating shaft mechanism 103.

[0539] For example, the first mating part 111 may have a raised second arc-shaped slider 1113 on the side facing the third mating part 211, and the third mating part 211 may have a second arc-shaped groove 2114 on the side facing the first mating part 111. The second arc-shaped slider 1113 can be inserted into the second arc-shaped groove 2114 and slide along the second arc-shaped groove 2114. The second arc-shaped groove 2114 and the second arc-shaped slider 1113 can form a second sliding structure 321 to realize the rotational engagement of the first mating part 111 and the third mating part 211.

[0540] The second mating part 113 may have a raised second arc-shaped slider 1133 on the side facing the fourth mating part 213, and the fourth mating part 213 may have a second arc-shaped groove 2133 on the side facing the second mating part 113. The second arc-shaped slider 1133 can be inserted into the second arc-shaped groove 2133 and slide along the second arc-shaped groove 2133. The second arc-shaped groove 2133 and the second arc-shaped slider 1133 can form a second sliding structure 322 to realize the rotational engagement of the second mating part 113 and the fourth mating part 213.

[0541] The shape and structure of the second arc-shaped slider 1133 can be the same as those of the second arc-shaped slider 1113, and the shape and structure of the second arc-shaped groove 2133 can be the same as those of the second arc-shaped groove 2114. The specific shapes and structures of the second arc-shaped slider 1133 and the second arc-shaped groove 2133 can be referred to the second arc-shaped slider 1113 and the second arc-shaped groove 2114.

[0542] There may be only one third sliding structure 331 between the third mating part 211 and the first friction member 12a, and only one third sliding structure 332 between the first friction member 12d and the fourth mating part 213. No adapters (such as the third adapter and the fourth adapter mentioned above) are provided between the third mating part 211 and the first friction member 12a, and between the first friction member 12d and the fourth mating part 213. The third mating part 211 and the first friction member 12a can directly rotate into contact, and the first friction member 12d and the fourth mating part 213 can also directly rotate into contact, further simplifying the structural design of the rotating shaft mechanism 103.

[0543] For example, the third mating part 211 may have a raised third arc-shaped slider 2115 on the side facing the first friction member 12a, and the first friction member 12a may have a third arc-shaped groove 128 on the side facing the third mating part 211. The third arc-shaped slider 2115 can be inserted into the third arc-shaped groove 128 and slide along the third arc-shaped groove 125. The third arc-shaped groove 128 and the third arc-shaped slider 2115 can form a third sliding structure 331 to realize the rotational mating of the third mating part 211 and the first friction member 12a.

[0544] The surface of the first friction member 12d facing the fourth mating part 213 may have a raised third arc-shaped slider 129, and the surface of the fourth mating part 213 facing the first friction member 12d may have a third arc-shaped groove 2134. The third arc-shaped slider 129 can be inserted into the third arc-shaped groove 2134 and slide along the third arc-shaped groove 2134. The third arc-shaped groove 2134 and the third arc-shaped slider 129 can form a third sliding structure 332 to realize the rotational engagement of the first friction member 12d and the fourth mating part 213.

[0545] The shape and structure of the third arc-shaped slider 129 and the third arc-shaped slide 2134 can be the same as those of the third arc-shaped slider 2115 and the third arc-shaped slide 128, respectively. The shape and structure of the third arc-shaped slider 129 and the third arc-shaped slide 2134 can be specifically referred to the third arc-shaped slider 2115 and the third arc-shaped slide 128.

[0546] In this embodiment, the first fixing member 11 further includes a first mounting portion 112 and a second mounting portion 114. The first mounting portion 112 is connected to the first mating portion 111, and the second mounting portion 114 is connected to the second mating portion 113. Exemplarily, the first mounting portion 112 and the second mounting portion 114 can be assembled together, and when assembling with the first housing of the electronic device, the second mounting portion 114 can be assembled with the first housing.

[0547] The second fastener 21 also includes a third mounting portion 212 and a fourth mounting portion 214. The third mounting portion 212 is connected to the third mating portion 211, and the fourth mounting portion 214 is connected to the fourth mating portion 213. For example, the third mounting portion 212 and the fourth mounting portion 214 can be assembled together, and when assembling with the second housing of the electronic device, the fourth mounting portion 214 can be assembled with the second housing.

[0548] The first mounting part 112 and the first mating part 111 can be integrated structural components, and the second mounting part 114 and the second mating part 113 can be integrated structural components, which helps to further simplify the structural design and reduce the size of the rotating shaft mechanism 103.

[0549] The third mounting part 212 and the third mating part 211 can be integrated structural components, and the fourth mounting part 214 and the fourth mating part 213 can be integrated structural components, which is conducive to further simplifying the structural design and reducing the size of the rotating shaft mechanism 103.

[0550] It should be noted that the first mating part 111 can be the portion of the first fixing member 11 that slides with the third mating part 211. For example, the first mating part 111 can be the portion of the first fixing member 11 that has a second arc-shaped slider 1113. Correspondingly, the third mating part 211 can be the portion of the second fixing member 21 that slides with the first mating part 111. For example, the third mating part 211 can be the portion of the second fixing member 21 that has a second arc-shaped groove 2114.

[0551] The second mating part 113 can be a portion of the first fixing member 11 that slides with the fourth mating part 213. For example, the second mating part 113 can be a portion of the first fixing member 11 that has a second arc-shaped slider 1133. The fourth mating part 213 can be a portion of the second fixing member 21 that slides with the second mating part 113. For example, the fourth mating part 213 can be a portion of the second fixing member 21 that has a second arc-shaped groove 2133.

[0552] The first mounting part 112 can be a part on the first fixing member 11 that is directly assembled and connected to the second mounting part 114. The second mounting part 114 can be a part on the first fixing member 11 that is directly assembled and connected to the first mounting part 112 and the first housing of the electronic device.

[0553] The third mounting part 212 can be a part on the second fixing member 21 that is directly assembled and connected to the fourth mounting part 214. The fourth mounting part 214 can be a part on the second fixing member 21 that is directly assembled and connected to the third mounting part 212 and the second housing of the electronic device.

[0554] In some examples, the first mounting portion 112 may be located on both sides of the first mating portion 111. For example, the first mounting portion 112 may include a first sub-mounting portion 112a and a second sub-mounting portion 112b, which may be located on both sides of the first mating portion 111.

[0555] The second mounting portion 114 may be located on both sides of the second mating portion 113. For example, the second mounting portion 114 may include a third sub-mounting portion 114a and a fourth sub-mounting portion 114b, which may be located on both sides of the second mating portion 113.

[0556] The dimensions of the first mounting portion 112 and the first mating portion 111 in the first direction (y-direction) can be smaller than those of the second mounting portion 114 and the second mating portion 113 in the first direction (y-direction). For example, the integrated structural member formed by the first mounting portion 112 and the first mating portion 111 can be a strip-shaped structure, and the integrated structural member formed by the second mounting portion 114 and the second mating portion 113 can be a plate-shaped structure.

[0557] Figure 40 for Figure 38 A front view of the central pivot mechanism.

[0558] In some examples, combined Figure 40 As shown, the torque structure 40 may include a second adjusting member 49 and a third adjusting member 410. The two ends of the first mounting portion 112 are connected to the two ends of the second mounting portion 114 via the second adjusting member 49 and the third adjusting member 410, respectively. For example, the first sub-mounting portion 112a and the third sub-mounting portion 114a may be connected via the third adjusting member 410, and the second sub-mounting portion 112b and the fourth sub-mounting portion 114b may be connected via the second adjusting member 49.

[0559] When the two ends of the first mounting part 112 and the second mounting part 114 are connected by the second adjusting member 49 and the third adjusting member 410, the second adjusting member 49 and the third adjusting member 410 can push the two ends of the first mounting part 112 toward the two ends of the second mounting part 114, so that the first mating part 111 connected to the first mounting part 112 undergoes a certain deformation, thereby pressing the first mating part 111, the second mating part 113 and the third mating part, the fourth mating part, the first friction member, the second friction member and other structural components located between the first mating part 111 and the second mating part 113, to ensure that the rotating shaft mechanism 103 can provide stable torque.

[0560] For example, after the rotating shaft mechanism reaches the required torque and is assembled, a gap may be maintained between the first mounting portion 112 and the second mounting portion 114, such as... Figure 40 The gap 103b in the middle. Of course, in some examples, after the first mounting part 112 and the second mounting part 114 are connected and locked by the second adjusting member, there may be no gap between the first mounting part 112 and the second mounting part 114, and the first mating part 111 will undergo a large deformation.

[0561] For example, the second adjusting member 49 and the third adjusting member 410 are movably mounted on the first mounting portion 112 and the second mounting portion 114. The second adjusting member 49 and the third adjusting member 410 can move along the first direction (y-direction) respectively, causing the two ends of the first mounting portion 112 to move towards or away from the two ends of the second mounting portion 114, adjusting the size of the gap 103b between the first mounting portion 112 and the second mounting portion 114, such as decreasing or increasing the width of the gap 103b, resulting in different deformations of the first mating portion 111, thus controlling the deformation of the first mating portion 111. This, in turn, adjusts the degree of compression between the structural components of the first mating portion 111 and the second mating portion 113, adjusting the friction between the structures, and thus adjusting the torque of the rotating shaft mechanism 103. Providing stable torque also meets different design requirements.

[0562] For example, the second adjusting member 49 and the third adjusting member 410 can be threaded into both ends of the second mounting portion 114 to achieve movable assembly of the second adjusting member 49 and the third adjusting member 410. Taking the second adjusting member 49 as an example, a first mating hole 112c can be formed on the second sub-mounting portion 112b of the first mounting portion 112 (refer to...). Figure 39 As shown), a second mating hole 112d can be opened on the fourth sub-mounting part 114b of the second mounting part 114. The inner surface of the second mating hole 112d can have an internal thread, such as the second mating hole 112d being a threaded hole.

[0563] One end of the second adjusting member 49 can be larger than the first mating hole 112c, so that one end of the second adjusting member 49 cannot pass through the first mating hole 112c, and one end of the second adjusting member 49 can abut against the second sub-mounting part 112b. The other end of the second adjusting member 49 can have an external thread that mates with the internal thread. For example, the second adjusting member 49 can be a screw or the like. The other end of the second adjusting member 49 can pass through the first mating hole 112c and be assembled with the second mating hole 112d.

[0564] Correspondingly, a third mating hole 112e can be provided on the first sub-mounting portion 112a of the first mounting portion 112, and a fourth mating hole 112f can be provided on the third sub-mounting portion 114a of the second mounting portion 114. The inner surface of the fourth mating hole 112f can have an internal thread. One end of the third adjusting member 410 can be larger than the third mating hole 112e, so that one end of the third adjusting member 410 can abut against the first sub-mounting portion 112a. The other end of the third adjusting member 410 can pass through the third mating hole 112e and be assembled with the fourth mating hole 112f.

[0565] Under the action of external force, rotating one end of the second adjusting member 49 and the third adjusting member 410 can make the second adjusting member 49 and the third adjusting member 410 rotate relative to the first mounting part 112 and the second mounting part 114 respectively, and move along the first direction (y direction) to realize the adjustment of torque.

[0566] See also Figure 39 As shown, a positioning element 48 may also be provided on the second mounting portion 114. For example, a protruding positioning element 48 may be provided on the side of the third sub-mounting portion 114a facing the first sub-mounting portion 112a, and a fourth mating hole 112f may be provided on the positioning element 48. This can provide a positioning function for the assembly of the third adjusting element 410 and the fourth mating hole 112f, facilitating the assembly and positioning of the third adjusting element 410.

[0567] For example, the positioning member 48 can be a raised columnar structure. It should be noted that the inner diameter of the third mating hole 112e can be larger than the outer diameter of the positioning member 48, so as to avoid the positioning member 48 affecting the adjustment of the gap width between the second mounting part 114 and the first mounting part 112, so that the rotating shaft mechanism 103 has a larger torque adjustment range.

[0568] The third mounting portion 212 and the fourth mounting portion 214 of the second fixing member 21 are assembled in an adjustable manner to facilitate the assembly of the second fixing member 21 with the second friction member 22. This ensures that during assembly or torque adjustment, the third mounting portion 212 and the fourth mounting portion 214 can move relative to each other along the first direction (y-direction) to compress the structural components.

[0569] For example, a slot 2122 may be provided on the third mounting part 212, and a protruding plug 2141 may be provided on the fourth mounting part 214. The slot 2122 may extend along the first direction (y direction), and the plug 2141 may be inserted into the slot 2122 and slide relative to the slot 2122, so that the third mounting part 212 and the fourth mounting part 214 are fitted together.

[0570] In some examples, to prevent the first and second rotating components from rotating further when they are deployed relative to each other to the open state of the shaft mechanism, the shaft mechanism may also include a stop structure. The stop structure may be located on at least one of the first, second, and third sliding structures.

[0571] For example, the stop structure can be disposed on the second sliding structure between the first assembly part and the third assembly part, or the stop structure can be disposed on the second sliding structure between the second assembly part and the fourth assembly part. This allows the stop structure to directly restrict the rotation of the first and second fixing members, resulting in high stability, and the structural design is relatively simple and easy to implement.

[0572] Figure 41 for Figure 39 A schematic diagram of the structure of the sliding fit between the first and third mating parts in the rotating shaft mechanism. Figure 42 for Figure 39 A schematic diagram of the structure of the third mating part and the first mating part slidingly mating in the rotating shaft mechanism.

[0573] For example, taking a second sliding structure between the first assembly part and the third assembly part as an example, which is provided with a stop structure, see [reference needed]. Figure 41 As shown, one end of the second arc-shaped slider 1113 of the second sliding structure may be provided with a protruding first abutment block 1115. See also Figure 42 As shown, a protruding second abutment block 2117 can be provided at one end of the second arc-shaped groove 2114. The first abutment block 1115 and the second abutment block 2117 can form a stop structure.

[0574] When the rotating shaft mechanism switches from the closed state to the open state, the second rotating component rotates relative to the first rotating component, and the second arc-shaped slide groove 2114 of the third mating part slides relative to the second arc-shaped slider 1113 of the first mating part, causing the second abutting block 2117 to slide toward the first abutting block 1115. When the rotating shaft mechanism 103 is in the open state, the second abutting block 2117 abuts against the first abutting block 1115, restricting the continued rotation of the third mating part (second fixing member) relative to the first mating part (first fixing member), thus keeping the rotating shaft mechanism in the open state.

[0575] A first abutting block can also be provided at one end of the second arc-shaped slide groove of the fourth mating part 213, and a second abutting block can also be provided at one end of the second arc-shaped slider of the second mating part 113. The setting position and structure of the first abutting block and the second abutting block can refer to the first abutting block and the second abutting block on the third mating part 211 and the first mating part 111.

[0576] In some examples, protruding structures may be provided on the opposite side surfaces of the first mating part 111 and the third mating part 211, and the portion of the second sliding structure along the rotation direction (the direction in which the second arc-shaped slider rotates relative to the second arc-shaped groove) is located on the protruding structure. The protruding structure enables adjustment of torque variations.

[0577] For example, see Figure 41 As shown, the first mating part 111 has a first protruding structure 1114 on one side 111a facing the third mating part. The end face of the first protruding structure 1114 is the first protruding surface 1114a. A portion of the second arc-shaped slider 1113 can be located on this side 111a of the first mating part 111, and a portion of the second arc-shaped slider 1113 can be located on the first protruding surface 1114a of the first protruding structure 1114. The height of the first protruding surface 1114a in the first direction (y direction) is higher than the height of the side 111a.

[0578] See Figure 42 As shown, the third mating part 211 has a second protruding structure 2116 on its side 211a facing the first mating part. The end face of the second protruding structure 2116 is the second protruding surface 2116a. A portion of the second arc-shaped groove 2114 can be located on this side 211a of the third mating part 211, and a portion of the second arc-shaped groove 2114 can be located on the second protruding surface 2116a of the second protruding structure 2116. The height of the second protruding surface 2116a in the first direction (y direction) is higher than the height of the side 211a.

[0579] Figure 43 for Figure 38 A schematic diagram of the structure of the rotating shaft mechanism 103 in the first intermediate state.

[0580] For example, when the rotating shaft mechanism 103 is in the first intermediate state (e.g.) Figure 43 In the first intermediate state shown, the included angle between the first rotating component 10 and the second rotating component 20 is 20°. Of course, in some other examples, when the rotating shaft mechanism 103 is in the first intermediate state, the included angle between the first rotating component 10 and the second rotating component 20 can be other values, such as 25°, 30°, etc.

[0581] When the rotating shaft mechanism 103 switches from the closed state to the first intermediate state, the second rotating component 20 rotates relative to the first rotating component 10, the third mating part 211 rotates relative to the first mating part 111, the second arc-shaped slide groove 2114 slides relative to the second arc-shaped slider 1113, the first protruding surface of the first protruding structure 1114 contacts and rubs against the side surface 211a of the third mating part 211, and the second protruding surface of the second protruding structure 2116 contacts the side surface 111a of the first mating part 111. The friction between the third mating part 211 and the first mating part 111 is relatively small, and the torque provided by the rotating shaft mechanism 103 is relatively small.

[0582] See Figure 43 As shown, when the rotating shaft mechanism 103 is in the first intermediate state, the second protrusion structure 2116 on the third mating part 211 slides to the position of the first protrusion structure 1114 on the first mating part 111.

[0583] Figure 44 for Figure 37 A magnified schematic diagram of a local structure in section D.

[0584] Combination Figure 43 and Figure 44 As shown, during the transition from the first intermediate state to the open state, the second arc-shaped slide groove 2114 slides relative to the second arc-shaped slider 1113, and the second protruding surface 2116a of the second protruding structure 2116 contacts and rubs against the first protruding surface 1114a of the first protruding structure 1114. This pushes the third mating part 211 in the first direction (y direction) to compress the first friction member 12, the second friction member 22, the fourth mating part 213, and the second mating part 113, increasing the rotational friction between the structural components, providing greater torque, and ensuring the hovering effect.

[0585] By using the protruding structure, the pivot mechanism 103 can generate varying torque during opening and closing, meeting different hovering requirements in different states and improving the damping feel during opening and closing. For example, when the pivot mechanism 103 is in a closed state or a relatively small angle intermediate state, such as when the included angle between the first rotating component 10 and the second rotating component 20 is 0° to 30°, the contact friction between the first rotating component 10 and the second rotating component 20 is small, and the torque of the pivot mechanism 103 is small. The magnitude of the torque can be selected and set according to actual needs; for example, the torque of the pivot mechanism 103 can be set to 0.

[0586] When the pivot mechanism 103 is in a relatively large angle intermediate state or open state, such as when the included angle between the first rotating component 10 and the second rotating component 20 is greater than 30° and less than or equal to 90°, the contact friction between the first rotating component 10 and the second rotating component 20 is large, and the torque and torque of the pivot mechanism 103 are large, which can achieve a better hovering effect.

[0587] It should be noted that in some examples, protruding structures can also be provided on the opposite sides of the second mating part 113 and the fourth mating part 213. For specific configuration and structure, please refer to the protruding structures on the first mating part 111 and the third mating part 211, so that when the rotating shaft mechanism 103 is in the middle state of a large angle, a better hovering effect can be achieved.
