Description

Technical Field

[0001] The present application relates to the field of electronic equipment, and in particular to a rotating mechanism, a housing device, and an electronic device. Background Art

[0002] With the continuous development of electronic devices, users' demands for the use of portable electronic devices are becoming increasingly diverse. In order to enhance the user experience, a reversible rotating mechanism is provided on the back side of the electronic device so that it can support the electronic device at a specific angle to meet the user's needs in different scenarios. The current rotating mechanism is usually fixed to the housing of the electronic device by screw locking. When the user needs to remove the rotating mechanism, it is usually necessary to flip the rotating mechanism to a larger opening and closing angle before using tools to remove the screws and take out the rotating mechanism. However, this disassembly method makes it difficult for the user to quickly disassemble and replace the rotating mechanism. At the same time, the user needs to open the rotating mechanism to a larger opening and closing angle before removing the rotating mechanism. Summary of the Invention

[0003] The embodiments of the present application provide a rotation mechanism, a housing device, and an electronic device, aiming to provide a rotation mechanism that can be quickly disassembled at a smaller opening and closing angle, a housing device including the rotation mechanism, and an electronic device including the housing device.

[0004] In a first aspect, a rotation mechanism is provided. The rotation mechanism has an open state and a closed state. The rotation mechanism includes a base and a support frame, and the support frame is rotatably connected to the base so that the support frame can be opened or closed relative to the base. The base is used to fix the shell body connected to the shell device, and the support frame is used to fix the support member connected to the shell device, and the support member can be opened or closed relative to the shell body under the action of the rotation mechanism. The rotation mechanism may also include a tongue and an elastic block, the tongue is fixed to one end of the base, and the elastic block is installed at the other end of the base, and part of the elastic block can protrude relative to the base, and at least part of the elastic block can retract relative to the base under the action of an external force, so that the rotation mechanism can be separated from the shell body.

[0005] It is understandable that, compared to a general rotation mechanism, it is necessary to lock the base with the shell body at least two places with screws. When the user needs to disassemble the rotation mechanism, it is necessary to open the support frame relative to the base to a larger opening and closing angle before using tools to remove multiple screws to remove the entire rotation mechanism from the shell body. The user's disassembly process is relatively cumbersome, the disassembly time is long, and the user experience is poor. The rotation mechanism in this embodiment can include an elastic block, a part of which can protrude relative to the base and cooperate with the shell body to enable the base of the rotation mechanism to be fixed to the shell body. When the user needs to remove the rotation mechanism from the shell body, he only needs to control the elastic block to retract relative to the base to operate the rotation mechanism to separate from the shell body, completing the disassembly of the rotation mechanism and the shell body. The disassembly method of the rotation mechanism and the shell body in this embodiment is simple to operate, does not require the use of additional tools, takes a short disassembly time, and provides a good user experience.

[0006] In one possible implementation, the outer surface of the base includes a top surface and a bottom surface disposed opposite each other, and a peripheral side surface connected between the top and bottom surfaces, with the top surface facing the direction in which the support frame opens relative to the base. The peripheral side surface includes a first external side surface and a second external side surface, the first external side surface and the second external side surface facing in different directions. The tongue is fixed to the first external side surface, and a portion of the elastic block protrudes relative to the second external side surface. This facilitates improved fixation stability between the base and the housing body, as the surface of the tongue fixedly connected to the base is different from the surface of the elastic block protruding relative to the base.

[0007] In one possible implementation, the extension direction of the tongue is parallel to the bottom surface, and / or the direction in which the elastic block slides relative to the base is parallel to the bottom surface. This arrangement helps reduce the thickness of the rotating mechanism, thereby achieving a thinner configuration of the rotating mechanism.

[0008] In one possible implementation, a mating groove is provided on the bottom surface, located between the tongue and the elastic block. It is understood that when the base is secured to the housing, both the tongue and the elastic block can be subjected to a downward force under the action of the housing. The mating groove can be used to mate with a fulcrum in the housing, so that the portion of the base located between the tongue and the elastic block can be subjected to an upward force. In this way, by ensuring that the forces acting on the two ends of the base are in the same direction and in the opposite direction to the forces acting on the middle portion of the base, the base can be locked to the housing, preventing the base from shaking relative to the housing.

[0009] In one possible implementation, the base has a receiving space and a first connecting hole, the first connecting hole connects to the receiving space and passes through the second outer side surface, the receiving space includes a first surface and a second surface that are arranged opposite to each other, and the first surface is located between the first connecting hole and the second surface. The elastic card block includes a mounting slider and an elastic element, a portion of the mounting slider and the elastic member are both accommodated in the receiving space, the elastic member is located between the mounting slider and the second surface, and a portion of the mounting slider can protrude relative to the second outer side surface through the first connecting hole. In this way, by providing a receiving space for accommodating the elastic card block in the base, the elastic card block can utilize the size space of the base to achieve spatial reuse. Secondly, a portion of the mounting slider protrudes relative to the second outer side surface through the first connecting hole, and the first connecting hole can also guide the mounting slider, so that the mounting slider can better cooperate with the shell body to achieve fixation.

[0010] In one possible implementation, the mounting slider includes a main body and a first protrusion. The main body is disposed within the receiving space, and the first protrusion is fixedly connected to a surface of the main body facing away from the elastic element. The elastic element abuts between the main body and the second surface, thereby abutting the main body against the first surface. The first protrusion is partially located in the first communication hole and partially protrudes relative to the second outer surface. Thus, while the first protrusion protrudes relative to the second outer surface, the first surface can block the main body, preventing it from sliding off the base under the action of the elastic element.

[0011] In one possible implementation, the base further includes a second communication hole that extends through the top surface and communicates with the receiving space. The mounting slider further includes a second protrusion that is fixedly connected to the surface of the main body facing the top surface, with the second protrusion partially located in the second communication hole and partially protruding relative to the top surface. Thus, by providing the second protrusion and having a portion of the second protrusion protrude relative to the top surface, a user can easily control the retraction of the elastic block relative to the base by moving the second protrusion, thereby improving the user experience.

[0012] In one possible implementation, the main body is provided with a groove, the opening of which is formed on the surface of the main body facing away from the first protrusion, and a portion of the elastic element is positioned within the groove. This groove thus serves to position the elastic element, ensuring that the direction of the elastic force of the elastic element aligns with the guiding direction of the first connecting hole, thereby preventing the mounting slider from becoming stuck during movement.

[0013] In one possible implementation, the base includes a first sub-base and a second sub-base, with the first sub-base fixedly connected to the second sub-base, and a portion of the first sub-base and a portion of the second sub-base together enclosing a receiving space. By splitting the base into the first and second sub-bases, the assembly difficulty of the slider can be reduced and assembly efficiency can be improved.

[0014] In one possible implementation, the base includes a first rotating body, and the support frame includes a second rotating body. One of the first rotating body and the second rotating body is an arc-shaped slide groove, and the other is an arc-shaped protrusion. The first rotating body cooperates with the second rotating body to rotate the support frame relative to the base. In this way, compared with the center of rotation of the support frame and the base being the center axis of the physical rotating shaft, when the rotating mechanism is applied to the shell device, the physical rotating shaft will protrude from the appearance surface of the shell device, resulting in an uneven appearance surface of the shell device. In this embodiment, the center of rotation of the support frame and the base relative to each other is a virtual axis. In this way, when the rotating mechanism is applied to the shell device, the appearance surface of the shell device can ensure its flatness.

[0015] In a second aspect, a shell device is provided. The shell device includes a shell body, a support member, and the above-mentioned rotating mechanism. The shell body has a receiving groove, and the rotating mechanism is received in the receiving groove. The receiving groove includes a groove bottom surface and a groove side surface connected to the periphery of the groove bottom surface. The shell body is provided with a first limiting groove and a second limiting groove, and the opening of the second limiting groove is formed on the groove side surface. At least a portion of the tongue of the rotating mechanism is inserted into the first limiting groove, and a portion of the elastic block is inserted into the second limiting groove to fix the base to the shell body. The support frame is fixedly connected to the support member. The support member can be opened or closed relative to the shell body under the action of the rotating mechanism. At least a portion of the elastic block can be retracted relative to the base and slide out of the second limiting groove under the action of an external force, so that the rotating mechanism can be separated from the shell body.

[0016] It is understandable that, compared to conventional rotation mechanisms, which require screws to secure the base to the housing at least in two locations, when the user needs to disassemble the rotation mechanism, they must open the support frame relative to the base to a wide angle, then use tools to remove multiple screws and remove the entire rotation mechanism from the housing. This makes the disassembly process more cumbersome, time-consuming, and less user-friendly. In contrast, in this embodiment, a first retaining groove and a second retaining groove are provided in the housing body. The rotating mechanism's tongue is inserted into the first retaining groove, and the rotating mechanism's elastic block is snapped into the second retaining groove. Thus, the first retaining groove and the tongue engage, and the second retaining groove and the elastic block engage, securing the base to the housing body. Thus, when the user needs to remove the rotation mechanism from the housing body, they simply retract the elastic block relative to the base to unlock the elastic block and the second retaining groove. Then, by withdrawing the tongue from the first retaining groove, the entire base can be detached from the housing body, completing the disassembly of the entire rotation mechanism. The disassembly method of the rotating mechanism and the shell body of this embodiment is simpler to operate, takes less time to disassemble, and provides a better user experience.

[0017] In one possible implementation, the housing device further includes a rear cover that is fixedly connected to the housing body and covers a portion of the receiving slot. When the rotating mechanism is in the closed state, the support member covers another portion of the receiving slot. In this way, the rear cover can conceal the receiving slot to ensure the appearance consistency of the housing device. Furthermore, when the rotating mechanism needs to be disassembled from the housing body, the user does not need to remove the rear cover; they only need to withdraw the tongue from the first limiting slot and the elastic block from the second limiting slot to detach the rotating mechanism from the housing body, making disassembly more convenient and quick.

[0018] In a possible implementation, the shell body further includes a fulcrum, the fulcrum is fixedly connected to the bottom surface of the groove and is located between the first limiting groove and the second limiting groove, and the fulcrum is at least partially embedded in the base.

[0019] It is understandable that when the base is fixed to the shell body, both the tongue and the elastic block can be subjected to a downward force under the action of the shell body. At this time, the fulcrum can push up a portion of the base between the portion where the tongue is fixed and the portion where the elastic block is installed. That is, the portion of the base that contacts the fulcrum can be located between the tongue and the elastic block and is subjected to an upward force. In this way, by making the force directions of the two ends of the base (that is, the ends where the tongue and the elastic block are provided) the same, and making the force direction of the portion of the base located between the tongue and the elastic block opposite to the force direction of the end of the base where the tongue is provided, the base can be fixed to the shell body while also being locked with the shell body to prevent the base from shaking relative to the shell body.

[0020] In one possible implementation, the second limiting groove includes a first surface and a second surface that are arranged relative to each other, the first surface and the second surface are arranged at an angle, the distance between the first surface and the second surface gradually increases in the direction approaching the receiving groove, and the elastic block abuts the first surface and the second surface. In this way, when the first protrusion of the mounting slide slides into the second limiting groove of the shell body, the first protrusion can cooperate with the first surface and the second surface of the second limiting groove and squeeze each other. The force exerted by the first surface and / or the second surface on the first protrusion can intersect with the direction of the first surface pointing to the second surface, so that the second limiting groove can better limit the first protrusion, prevent the first protrusion from shaking in the second limiting groove, thereby preventing the rotating mechanism from shaking and affecting the user experience.

[0021] In one possible implementation, the housing body further includes an undercut structure, which includes a first portion and a second portion. The first portion is fixedly connected to the end of the second portion and is disposed at an angle to the second portion. The first portion is fixedly connected to the bottom surface of the groove, and the second portion is spaced apart from the bottom surface of the groove. The first portion, the second portion, and the bottom surface of the groove together enclose a first limiting groove. At least a portion of the tongue is located within the first limiting groove and contacts the second portion of the undercut structure. In this way, by providing the first limiting groove between the undercut structure and the bottom wall of the groove, it is possible to avoid notching the side walls of the receiving groove, thereby avoiding occupying space for other devices installed within the housing body.

[0022] In a third aspect, a housing device is provided. The housing device includes a housing body, a support member, and a rotating mechanism. The housing body has a receiving groove, which includes a groove bottom surface and groove side surfaces connected to the periphery of the groove bottom surface. The rotating mechanism is received in the receiving groove. The rotating mechanism includes a base and a support frame. The support frame is rotatably connected to the base so that the support frame can be opened or closed relative to the base. The base is fixedly connected to the housing body, and the support frame is fixedly connected to the support member. The support member can be opened or closed relative to the housing body under the action of the rotating mechanism. The rotating mechanism includes a tongue and a top block. The tongue is fixed to one end of the base, and the top block is fixed to the other end of the base. The housing body is provided with a first limiting groove, and at least a portion of the tongue is inserted into the first limiting groove. The housing device further includes an elastic stopper, which is mounted on the housing body. The elastic stopper partially extends from the receiving groove and forms a second stopper with the bottom surface of the receiving groove. The top block is inserted into the second stopper and abuts against the elastic stopper. Under the action of an external force, the elastic stopper can at least partially withdraw from the receiving groove, causing the top block to disengage from the second stopper, thereby allowing the rotation mechanism to be separated from the housing body. Thus, compared to installing an elastic block in the base to cooperate with the second stopper of the housing body to achieve fixation, in this embodiment, the elastic stopper is provided in the second stopper groove to cooperate with the top block on the base to achieve fixation, thereby reducing the number of parts of the rotation mechanism, thereby simplifying the structural arrangement of the rotation mechanism, and facilitating a streamlined assembly process and reducing costs.

[0023] In one possible implementation, the housing device further includes a back cover, which is fixedly connected to the housing body and covers a portion of the receiving groove. When the rotating mechanism is in a closed state, the support member covers another portion of the receiving groove. The projections of the back cover and the tongue on the bottom surface of the groove at least partially overlap. When the rotating mechanism is in a closed state, the projections of the support member and the top block on the bottom surface of the groove at least partially overlap. In this way, the back cover can shield the receiving groove to ensure the appearance consistency of the housing device. At the same time, when the rotating mechanism needs to be disassembled from the housing body, the user does not need to remove the back cover. The user only needs to withdraw the tongue from the first limiting groove and the elastic block from the second limiting groove to detach the rotating mechanism from the housing body, making disassembly more convenient and quick.

[0024] In one possible implementation, the housing body further comprises a fulcrum, the fulcrum being fixedly connected to the bottom surface of the groove and being located between the first limiting groove and the second limiting groove, the fulcrum being at least partially embedded in the base. It is understood that when the base is fixed to the housing body, both the tongue and the elastic block can be subjected to a downward force under the action of the housing body. At this time, the fulcrum can upwardly lift a portion between the portion of the base fixedly connected to the tongue and the portion of the base mounted with the elastic block. That is, the portion of the base in contact with the fulcrum can be located between the tongue and the elastic block and subjected to an upward force. Thus, by ensuring that the force directions of the two ends of the base (i.e., the ends with the tongue and the elastic block) are the same, and ensuring that the force direction of the portion of the base located between the tongue and the elastic block is opposite to the force direction of the end of the base with the tongue, the base can be fixed to the housing body while also being locked to the housing body to prevent the base from shaking relative to the housing body.

[0025] In a fourth aspect, a rotation mechanism is provided. The rotation mechanism has an open state and a closed state. The rotation mechanism includes a base, a support frame, and a locking member. The support frame is rotatably connected to the base so that the support frame can be opened or closed relative to the base. The support frame includes a top surface and a bottom surface arranged opposite to each other, and a peripheral side surface connected between the top surface and the bottom surface. The support frame has a first mounting hole and a second mounting hole. The first mounting hole passes through the top and bottom surfaces of the support frame, and the second mounting hole passes through the peripheral side surface of the support frame and is connected to the first mounting hole. The first mounting hole includes a first side wall, which is opposite to and spaced from the second mounting hole. The locking member is mounted in the second mounting hole and is rotatably connected to the support frame, with a portion of the locking member located within the first mounting hole. The locking member can rotate relative to the support frame to switch between a locked state and an unlocked state. When the locking member is in the locked state, the distance between the locking member and the first side wall is a first distance. When the locking member is in the unlocked state, the distance between the locking member and the first side wall is a second distance, and the first distance is smaller than the second distance.

[0026] It is understandable that compared to a typical rotating mechanism that uses screws to lock the support frame and the support member to secure the support member to the rotating mechanism's frame, when the user needs to disassemble the rotating mechanism, the support frame must be opened to a larger angle relative to the base before using tools to remove the screws and remove the support member from the rotating mechanism. This user disassembly process is cumbersome, takes a long time, and provides a poor user experience.

[0027] The first mounting hole of the rotating mechanism in this embodiment can be used to accommodate a portion of the support member. When a portion of the support member is located within the first mounting hole, the locking member can be rotated to a locked state, reducing the distance between the locking member and the first side wall, allowing the locking member to squeeze the support member. At this point, the support member can be pressed against the wall of the first mounting hole under the force of the locking member, thereby locking with the support frame. When the user needs to remove the support member from the rotating mechanism, they simply rotate the locking member from the locked state to the unlocked state, increasing the distance between the locking member and the first side wall. This relieves the force between the locking member and the support member, allowing the user to detach the support member from the support frame, thereby achieving removal of the support member. Furthermore, when the user needs to remove the support member, they simply open the rotating mechanism to a small angle to expose the locking member, and then rotate the locking member to unlock it. The disassembly method of the rotating mechanism and support member in this embodiment is simple to operate, does not require additional tools, and takes a short time to disassemble. The rotating mechanism in this embodiment can achieve quick disassembly of the rotating mechanism and support member even at a small opening and closing angle, providing a good user experience.

[0028] In one possible implementation, the locking member includes a disc-shaped cam portion that is rotatably connected to the support frame, with the center of rotation of the cam portion relative to the support frame spaced apart from the geometric center of the cam portion. This arrangement creates an eccentric cam structure, allowing the cam portion to rotate to adjust the distance between the locking member and the first side wall. This simplifies the locking member's structural design and reduces assembly complexity.

[0029] In one possible implementation, the locking member further includes an extension portion that is fixedly connected to a portion of the lateral surface of the cam portion, the extension portion being spaced apart from the first mounting hole, and at least a portion of the extension portion being exposed relative to the second mounting hole. This extension portion allows the user to easily control the rotation of the locking member via the extension portion to switch the locking member between a locked and unlocked state, providing a better user experience.

[0030] In one possible implementation, the support frame also has an avoidance hole, which is located on the side of the first mounting hole facing away from the second mounting hole. The wall of the avoidance hole facing the first mounting hole is the first hole wall. The support frame also has a limiting groove, and the opening of the limiting groove is formed in the first hole wall. The limiting groove and the avoidance hole are both used to accommodate a part of the support member.

[0031] It will be appreciated that the support frame in this embodiment further includes a relief hole spaced apart from the first mounting hole. The relief hole may include a first hole wall facing the first mounting hole, and a retaining groove formed in the first hole wall. When the support member is secured to the support frame, a portion of the support member may be located within the relief hole, while a portion may also be located within the retaining groove. Thus, when the locking member is in the locked state and the locking member compresses a portion of the support member, the support member may also compress the first hole wall under the force of the locking member, and a portion of the support member may also be embedded in the retaining groove, thereby locking the support member to the support frame. In other words, in this embodiment, the relief hole spaced apart from the first mounting hole is provided to accommodate a portion of the support member, and the retaining groove is provided in the first hole wall of the relief hole to retain a portion of the support member, thereby further securing the support member to the support frame. Furthermore, when the user needs to remove the support member from the support frame, they simply rotate the locking member to unlock it and slide a portion of the support member out of the retaining groove to unlock the support member from the support frame. The disassembly method of the rotating mechanism and the support member of this embodiment is simple to operate, does not require the use of tools, and takes a short time to disassemble. The rotating mechanism of this embodiment can also realize the rapid disassembly of the rotating mechanism and the support member at a small opening and closing angle, and the user experience is good.

[0032] In one possible implementation, the retaining groove is conical or truncated cone-shaped. This allows the retaining groove to have a larger opening when a portion of the support member needs to be installed within the retaining groove, facilitating installation of the support member. Furthermore, when a portion of the support member is embedded within the retaining groove, the sidewalls of the retaining groove can retain the portion of the support member within the retaining groove, thereby preventing the support member from shaking and improving the user experience.

[0033] In one possible implementation, the support frame is further provided with a retaining groove, the opening of which is formed in the first side wall, and the retaining groove is configured to receive a portion of the support member. Thus, when the locking member is in a locked state and the locking member squeezes a portion of the support member, the support member can also squeeze the first hole wall under the force of the locking member, and a portion of the support member can also be embedded in the retaining groove, thereby locking the support member and the support frame, thereby improving the fixing stability of the support member and the support frame.

[0034] In a fifth aspect, a housing device is provided. The housing device includes a housing body, a support member, and the aforementioned rotation mechanism. The base of the rotation mechanism is fixedly connected to the housing body, and the support member is detachably connected to the support member. The support member can be opened or closed relative to the housing body under the action of the rotation mechanism. When the locking member is in the locked state, the support member is fixedly connected to the support member. When the locking member is in the unlocked state, the support member can be separated from the support member.

[0035] It is understandable that compared to a typical rotating mechanism that uses screws to lock the support frame and the support member to secure the support member to the rotating mechanism's frame, when the user needs to disassemble the rotating mechanism, the support frame must be opened to a larger angle relative to the base before using tools to remove the screws and remove the support member from the rotating mechanism. This user disassembly process is cumbersome, takes a long time, and provides a poor user experience.

[0036] The first mounting hole of the rotating mechanism in this embodiment can be used to accommodate a portion of the support member. When a portion of the support member is located within the first mounting hole, the locking member can be rotated to a locked state, reducing the distance between the locking member and the first side wall, allowing the locking member to squeeze the support member. At this point, the support member can be pressed against the wall of the first mounting hole under the force of the locking member, thereby locking with the support frame. When the user needs to remove the support member from the rotating mechanism, they simply rotate the locking member from the locked state to the unlocked state, increasing the distance between the locking member and the first side wall. This relieves the force between the locking member and the support member, allowing the user to detach the support member from the support frame, thereby achieving removal of the support member. Furthermore, when the user needs to remove the support member, they simply open the rotating mechanism to a small angle to expose the locking member, and then rotate the locking member to unlock it. The disassembly method of the rotating mechanism and support member in this embodiment is simple to operate, does not require additional tools, and takes a short time to disassemble. The rotating mechanism in this embodiment can achieve quick disassembly of the rotating mechanism and support member even at a small opening and closing angle, providing a good user experience.

[0037] In one possible implementation, the support member includes a support body and a first mounting portion, the support body overlaps the top surface of the support frame, the first mounting portion is located on the side of the support body facing the support frame, and is fixedly connected to the support frame, and at least a portion of the first mounting portion is located in the first mounting hole of the support frame and is located between the first side wall and the locking member. When the locking member is in a locked state, the first mounting portion squeezes the first side wall under the action of the locking member, and when the locking member is in an unlocked state, the first mounting portion is spaced apart from the first side wall and / or the locking member. In this way, through the above-mentioned arrangement, the user only needs to operate the locking member to be in the unlocked state to relieve the force between the first mounting portion and the first side wall, thereby facilitating the user to detach the support member from the support frame. The disassembly method is simple to operate, does not require the use of additional tools, and takes a short time to disassemble.

[0038] In one possible implementation, the first mounting hole further includes a second sidewall disposed opposite the first sidewall, and the spacing between the first and second sidewalls is a first dimension. The first mounting portion includes a first surface and a second surface disposed opposite each other, the first surface being disposed toward the first sidewall, and the spacing between the first and second surfaces is a second dimension, which is smaller than the first dimension. Thus, with this arrangement, when the locking member is unlocked, the first mounting portion has sufficient room to move, allowing the first mounting portion to be removed from the first mounting hole, thereby separating the support member from the bracket.

[0039] In a sixth aspect, a rotation mechanism is provided. The rotation mechanism has an open state and a closed state. The rotation mechanism includes a base, a support frame, a first rotating member, a first friction plate, and a second friction plate. The support frame is rotatably connected to the base so that the support frame can be opened or closed relative to the base. The rotation axis of the support frame relative to the base is a first axis. The first friction plate includes a first movable end and a second movable end. The first movable end is mounted on the first rotating member and the second movable end is movably connected to the base. The second friction plate includes a first connecting end and a second connecting end. The first connecting end is mounted on the first rotating member and abuts the first movable end. The second connecting end is fixedly connected to the support frame. The central axis of the first rotating member is the first rotation center, and the first rotation center is spaced apart from the first axis. When the support frame rotates relative to the base, the second friction plate rotates relative to the base around the first axis under the action of the support frame. The first connecting end of the second friction plate rotates relative to the first movable end of the first friction plate around the first rotation center to provide torque for the rotation mechanism. The second movable end of the first friction plate slides relative to the base under the action of the second friction plate and rotates relative to the base.

[0040] It is understandable that the support frame of a general rotating mechanism is usually connected to the base through a physical rotating shaft, or the support frame is connected to the base through a circular shape and the shaft core. The physical rotating shaft and the shaft core need to withstand axial torque. In order to support the placement of electronic equipment at different angles, the rotating mechanism needs to provide a larger torque for the support. In order to increase the torque, the general rotating mechanism usually also needs to increase the diameter of the physical rotating shaft or the diameter of the shaft core so that it can withstand a larger axial torque to meet the large torque requirements. However, as the diameter of the physical rotating shaft or the shaft core increases, the overall thickness of the rotating mechanism also increases, which is not conducive to the thinning setting of the electronic equipment.

[0041] The torsion mechanism in this embodiment includes a first rotating member, a first friction plate, and a second friction plate. The first movable end of the first friction plate is rotatably connected to the first connecting end of the second friction plate, while the second connecting end of the second friction plate is fixedly connected to a support frame. The first movable end of the first friction plate abuts the first connecting end of the second friction plate, with no gap between them. When the support frame rotates relative to the base, the support frame drives the second friction plate to rotate relative to the base. At this time, the first connecting end of the second friction plate can rotate relative to the first movable end of the first friction plate. The second movable end of the first friction plate can slide relative to the base. The first friction plate can also move relative to the base under the action of the second friction plate. Frictional force is generated between the first and second friction plates, providing torsion for the rotating mechanism. At this time, the first rotating member is only subjected to tensile and compressive forces along its axial direction, resulting in relatively low forces. As a result, the diameter of the first rotating member is not limited by the torque generated by the rotating mechanism. In other words, the diameter of the first rotating member in this embodiment can be made smaller, allowing the rotating mechanism to achieve high torque while maintaining a relatively thin overall thickness, thus facilitating a thinner design.

[0042] Secondly, the torque generated by the torsion structure in this embodiment is independent of the angle at which the support frame rotates relative to the base. The torsion structure can provide torque at any position of the support frame relative to the base. In other words, the rotation mechanism in this embodiment can also achieve hovering of the support frame and the base at any angle, meeting the user's diverse usage needs. Furthermore, the force required to open the support frame relative to the base 510 to different angles is relatively consistent. In other words, the force required to open and close the rotation mechanism does not vary with the angle of opening and closing, which improves the user experience.

[0043] In one possible implementation, the rotation mechanism further includes a third friction plate and a second rotating member. The third friction plate includes a first connecting end and a second connecting end. The first connecting end of the third friction plate and the second movable end of the first friction plate are both sleeved on the second rotating member. The first connecting end of the third friction plate is disposed in close contact with the second movable end. The second connecting end of the third friction plate is slidably connected to the base. The central axis of the second rotating member serves as the second rotation center. When the support frame rotates relative to the base, the second movable end of the first friction plate, under the action of the second friction plate, rotates relative to the first connecting end of the third friction plate about the second rotation center to provide torque to the rotation mechanism. The second connecting end of the third friction plate, under the action of the first friction plate, slides relative to the base.

[0044] It is understood that the torsion structure in this embodiment may also include a second rotating member and a third friction plate. The second movable end of the first friction plate is rotatably connected to the first connecting end of the third friction plate via the second rotating member, and the second connecting end of the third friction plate is slidably connected to the base. The second movable end of the first friction plate and the second connecting end of the third friction plate are stacked in the third direction and contact each other with no gap between them. When the support frame rotates relative to the base, the support frame drives the first connecting end of the second friction plate to slide relative to the base and rotate relative to the first movable end of the first friction plate. Friction is generated between the first and second friction plates. The second movable end of the first friction plate slides relative to the base under the action of the second friction plate, driving the third friction plate to slide relative to the base. At this time, the second movable end of the first friction plate and the first connecting end of the third friction plate rotate relative to each other, generating friction between the first and third friction plates. The second rotating member is subjected only to tensile and compressive forces along its axial direction. In this way, friction is generated by enabling the first friction plate to rotate relative to the second and third friction plates, providing torsion for the entire rotating mechanism. That is, the rotation mechanism can generate torque at the relative rotation center between the first and second friction plates (in this embodiment, the first rotation center), and at the relative rotation center between the first and third friction plates (in this embodiment, the second rotation center). Compared to conventional rotation mechanisms that generate torque at only one rotation center, the rotation mechanism in this embodiment, by disposing a third friction plate between the second movable end of the first friction plate and the base, allows the first and third friction plates to rotate relative to each other while also generating torque. In other words, while the dimensions of the rotation mechanism remain the same, the rotation mechanism in this embodiment can generate torque at two rotation centers (in this embodiment, the first and second rotation centers), thereby achieving both a compact design and high torque.

[0045] In one possible implementation, the rotation mechanism further includes a first slider and a second slider, the first slider and the second slider being disposed opposite each other and spaced apart, each being slidably connected to the base, and the second connection end of the third friction plate being fixedly connected to the first and second sliders. Thus, the third friction plate can be slidably connected to the base via the first and second sliders, simplifying the structural configuration of the third friction plate and reducing manufacturing difficulty.

[0046] In one possible implementation, the first rotating member includes a first end, a shaft, and a second end connected in sequence. The first movable end of the first friction plate and the first connecting end of the second friction plate are both sleeved on the shaft. The first end presses the first and second friction plates in a direction toward the second end, and the second end presses the first and second friction plates in a direction toward the first end. In this way, by arranging the two ends of the first rotating member to press the first and second friction plates from both sides, the positive pressure between the first and second friction plates is increased, thereby increasing the friction force when the first friction plate rotates relative to the second friction plate, thereby increasing the torque when the support frame rotates relative to the base.

[0047] In one possible implementation, a support frame includes a support body, a first baffle, and a second baffle. The support body is rotatably connected to a base. The support body has an installation space. The first baffle and the second baffle are both located in the installation space and fixedly connected to the support body. The first baffle and the second baffle are spaced apart in the thickness direction of the support frame. At least a portion of the second friction plate is located in the installation space, between the first baffle and the second baffle. Thus, by arranging the first and second baffles within the installation space of the support body, the structural stability of the support body can be enhanced. Furthermore, the first and second baffles can also support the second friction plate. When the support frame is overloaded, the support body and the second friction plate can still maintain structural stability, thereby effectively preventing deformation of the support frame and / or the second friction plate due to the overload. Furthermore, the first and second baffles can also prevent relative rotation of the second friction plate and the support frame.

[0048] In one possible implementation, the number of first friction plates and the number of second friction plates are both multiple, and the first movable ends of the multiple first friction plates and the first connecting ends of the multiple second friction plates are alternately arranged in sequence along the axial direction of the first rotating part and are arranged close to each other.

[0049] It will be appreciated that the rotation mechanism in this embodiment can include multiple first friction plates and multiple second friction plates, which are alternately arranged in sequence along the axial direction of the first rotating member (i.e., the width direction of the rotation mechanism). This increases the total friction area between the multiple first friction plates and the multiple second friction plates, thereby effectively increasing the friction force during relative rotation between the multiple first friction plates and the multiple second friction plates, thereby increasing torque. Furthermore, the multiple first friction plates and the multiple second friction plates are arranged along the width direction of the rotation mechanism, without affecting the thickness of the rotation mechanism. In other words, the rotation mechanism in this embodiment can achieve a thin configuration while maintaining high torque, thereby facilitating a thin configuration of the entire electronic device.

[0050] In one possible implementation, the base includes a first rotating body, and the support frame includes a second rotating body. One of the first rotating body and the second rotating body is an arc-shaped slide groove, and the other is an arc-shaped protrusion. The first rotating body cooperates with the second rotating body to rotate the support frame relative to the base. In this way, compared with the center of rotation of the support frame and the base being the center axis of the physical rotating shaft, when the rotating mechanism is applied to the shell device, the physical rotating shaft will protrude from the appearance surface of the shell device, resulting in an uneven appearance surface of the shell device. In this embodiment, the center of rotation of the support frame and the base relative to each other is a virtual axis. In this way, when the rotating mechanism is applied to the shell device, the appearance surface of the shell device can ensure its flatness.

[0051] In a seventh aspect, a rotation mechanism is provided. The rotation mechanism has an open state and a closed state. The rotation mechanism includes a base, a support frame, a first rotating member, a second rotating member, and a torsion member. The support frame includes a support frame body and a transmission member. The support frame body is rotatably connected to the base. The transmission member is fixedly connected to the support frame body. The transmission member includes a first gear. The first rotating member includes a first rotating shaft and a second gear. The second gear is mounted on and fixed to the first rotating shaft. Both ends of the first rotating shaft are rotatably connected to the base. The second rotating member includes a second rotating shaft. Both ends of the second rotating shaft are rotatably connected to the base. The second gear meshes with the first gear. The torsion member includes a first end and a second end. The first end of the torsion member is mounted on the first rotating shaft and has an interference fit with the first rotating shaft. The second end of the torsion member is mounted on the second rotating shaft. When the support frame rotates relative to the base, the first gear rotates relative to the base. The second gear rotates relative to the base under the action of the first gear. The first rotating shaft rotates relative to the first end of the torsion member under the action of the second gear to provide torque for the rotation mechanism.

[0052] It's understandable that the support frame of a typical rotating mechanism is typically connected to the base via a physical shaft, or the support frame is connected to the base via a circle that cooperates with the shaft core. Therefore, when the rotating mechanism is in the open position, the physical shaft is exposed relative to the electronic device, and the circle is also exposed relative to the electronic device due to its rotation relative to the base. This reduces the overall aesthetics of the electronic device and the user experience.

[0053] The support frame of the rotating mechanism in this embodiment may be provided with a first gear. The torsion structure may include a first rotating member, a second rotating member and a torsion member. The first rotating member and the second rotating member may both be mounted on the base. The first rotating member may include a first rotating shaft and a second gear sleeved and fixed on the first rotating shaft. That is, the first rotating member is a gear shaft structure. The first end of the torsion member may be sleeved on the first rotating shaft and interfere with the first rotating shaft. The second end of the torsion member may be sleeved on the second rotating member. The first gear of the support frame may mesh with the second gear of the first rotating member. When the support frame rotates relative to the base, the first gear of the support frame may drive the second gear of the first rotating member to rotate. The first rotating shaft of the first rotating member may rotate relative to the first end of the torsion member under the action of the second gear, thereby generating torque. The torsion structure as a whole will not move or rotate relative to the base. In this way, by setting up a gear transmission, when the rotating mechanism is in the open state, the torsion structure as a whole will not rotate relative to the base, so that the torsion structure can be better hidden in the rotating mechanism and will not be exposed relative to the electronic device, which is beneficial to improving the overall aesthetics of the electronic device and enhancing the user experience.

[0054] Secondly, the torque generated by the torsion structure in this embodiment is independent of the angle at which the support frame rotates relative to the base. The torsion structure can provide torque regardless of the support frame's relative rotation position. In other words, the rotation mechanism in this embodiment can also enable the support frame and base to hover at any angle, meeting the user's diverse usage needs. Furthermore, the force required to open the support frame relative to the base to different angles is relatively consistent, meaning the force required to open and close the rotation mechanism does not vary with the angle, improving the user experience.

[0055] In one possible implementation, the second rotating member further includes a third gear, which is sleeved and fixed to the second rotating shaft and meshes with the second gear. The second end of the torsion member is sleeved on the second rotating shaft and has an interference fit with the second rotating shaft. When the support frame rotates relative to the base, the third gear rotates relative to the base under the action of the second gear, and the second rotating shaft rotates relative to the second end of the torsion member under the action of the third gear, thereby providing torque to the rotating mechanism.

[0056] It is understandable that the support frame of a general rotating mechanism is usually connected to the base through a physical rotating shaft, or the support frame is connected to the base through a circular shape and the shaft core. The physical rotating shaft and the shaft core need to withstand axial torque. In order to support the placement of electronic equipment at different angles, the rotating mechanism needs to provide a larger torque for the support. In order to increase the torque, the general rotating mechanism usually also needs to increase the diameter of the physical rotating shaft or the diameter of the shaft core so that it can withstand a larger axial torque to meet the large torque requirements. However, as the diameter of the physical rotating shaft or the shaft core increases, the overall thickness of the rotating mechanism also increases, which is not conducive to the thinning setting of the electronic equipment.

[0057] In this embodiment, the second rotating member may include a second rotating shaft and a third gear mounted on the second rotating shaft. That is, the second rotating member also comprises a gear shaft structure. The third gear may mesh with the second gear. The first and second rotating members may be arranged along the longitudinal extension direction of the rotating mechanism (i.e., the second direction in this embodiment). Thus, when the support frame rotates relative to the base, the support frame's first gear drives the first rotating member's second gear to rotate, causing the first rotating shaft of the first rotating member and the first end of the torsion member to rotate relative to each other, thereby generating torque. The first rotating member's second gear may also drive the third gear to rotate, causing the second rotating shaft of the second rotating member and the second end of the torsion member to rotate relative to each other, thereby generating torque, thereby increasing the total torque of the entire rotating mechanism. In other words, by providing multiple intermeshing gear shafts (i.e., the first and second rotating members in this embodiment) along the longitudinal extension direction of the rotating mechanism, the rotating mechanism in this embodiment can increase the total torque of the entire rotating mechanism without increasing the overall thickness of the rotating mechanism. The rotating mechanism in this embodiment can achieve a thin design while maintaining high torque, thereby facilitating a thinner design for the entire electronic device.

[0058] In one possible implementation, the first gear includes a meshing portion and a non-meshing portion sequentially connected along its circumference, the meshing portion being used to mesh with the second gear of the first rotating member, and the non-meshing portion being used to avoid the second gear. When the rotating mechanism is in a closed state, part of the second gear is arranged opposite the non-meshing portion, and the open state of the rotating mechanism includes a first state and a second state. When the rotating mechanism switches from the closed state to the first state, the support frame opens relative to the base, the first gear rotates relative to the base, and the second gear remains stationary until the meshing portion contacts the second gear. When the rotating mechanism switches from the first state to the second state, the support frame opens relative to the base, the first gear rotates relative to the base, and the second gear rotates relative to the base under the action of the first gear.

[0059] In one possible implementation, the non-meshing portion includes a first surface, a second surface, and a third surface, wherein the first surface and the second surface have a step difference, and the third surface is connected between the first surface and the second surface and forms an avoidance groove with the first surface and the second surface. The second gear includes a first sub-gear and a second sub-gear, both of which are sleeved and fixed to the first rotating shaft. The first sub-gear includes a first special-shaped tooth, and the central axis of the tooth top surface of the first special-shaped tooth and the central axis of the second gear are located on opposite sides of the tooth top surface of the first special-shaped tooth. The second sub-gear is used to mesh with the meshing portion of the first gear. When the rotating mechanism is in a closed state, part of the second sub-gear is located in the avoidance groove and is arranged opposite to the first surface. The tooth top surface of the first special-shaped tooth is arranged opposite to the second surface of the non-meshing portion.

[0060] It will be appreciated that the first gear of the support frame in this embodiment includes an engaging portion and a non-engaging portion. When the rotation mechanism is in the closed state, the engaging portion of the first gear can be spaced apart from the second gear. The non-engaging portion of the first gear can be positioned opposite the second gear. When the support frame is opened to a first angle relative to the base, the support frame can rotate relative to the base, driving the first gear to rotate. The first gear and the second gear do not mesh, meaning that the second gear does not rotate with the rotation of the first gear. Thus, relative rotation between the first and second rotating members and the torsion member does not occur, and the torsion structure does not generate torque. This reduces the force required to open the support frame relative to the base to a certain angle. When the support frame is opened relative to the base until the first meshing teeth of the engaging portion of the first gear contact and mesh with the second gear, if the opening and closing angle between the support frame and the base is further increased, the first gear can maintain meshing with the second gear, driving the second gear to rotate, allowing the first rotating member to rotate relative to the torsion member and generate torque. In other words, the rotation mechanism in this embodiment can ensure that the first rotating member does not rotate when the opening angle is small, so that the torsion structure does not generate torque, thereby reducing the opening and closing force required by the user to open the support frame and improving the opening and closing experience.

[0061] In one possible implementation, the spacing between the tooth top surface of the first special-shaped tooth and the second surface is less than or equal to 0.05 mm. In this way, the gap between the tooth top surface of the first special-shaped tooth and the second surface of the non-meshing portion of the first gear is small. When the rotating mechanism is in a closed state, the second surface can limit the tooth top surface of the first special-shaped tooth, thereby avoiding the problem that when the rotating mechanism is in a closed state, the first rotating member rotates at a large angle, resulting in the first gear of the support frame being unable to engage with the second gear of the first rotating member when the support frame of the rotating mechanism is opened relative to the base. At the same time, there is a gap between the tooth top surface of the first special-shaped tooth and the second surface of the non-meshing portion to facilitate assembly.

[0062] In one possible implementation, the second rotating member further includes a third gear, which includes a third sub-gear and a fourth sub-gear. Both the third sub-gear and the fourth sub-gear are sleeved and fixed to the second rotating shaft. The third sub-gear includes a second special-shaped tooth, with the central axis of the tooth top surface of the second special-shaped tooth and the central axis of the third gear located on opposite sides of the tooth top surface of the second special-shaped tooth. The fourth sub-gear is configured to mesh with the second sub-gear. The second special-shaped tooth is configured to avoid the first special-shaped tooth during rotation of the fourth sub-gear relative to the base under the influence of the second sub-gear. Thus, by arranging the second sub-gear of the second gear to mesh with the fourth sub-gear of the third gear, the second gear can remain meshed with the third gear regardless of the state of the rotating mechanism. This prevents the second gear from disengaging from the third gear when the second gear rotates until the first special-shaped tooth surface faces the second special-shaped tooth. This would result in the third gear not rotating with the second gear, causing a sudden change in the torque of the torsion structure and affecting the user's opening and closing experience.

[0063] In one possible implementation, the second gear and the third gear are identical in shape and size. The first sub-gear further includes a third special-shaped tooth, which is identical in shape and size to the second special-shaped tooth. The third sub-gear further includes a fourth special-shaped tooth, which is identical in shape and size to the first special-shaped tooth. When the rotating mechanism is in a closed state, the top surface of the third special-shaped tooth is parallel to the top surface of the second special-shaped tooth, and the top surface of the fourth special-shaped tooth is parallel to the top surface of the first special-shaped tooth. It will be understood that the second gear and the third gear in this embodiment are identical in shape and size, allowing them to be manufactured using the same mold, which helps simplify the manufacturing process and improve manufacturing accuracy.

[0064] In one possible implementation, the torque member includes a concave cam and a first elastic member. The concave cam includes a first end and a second end. The first end of the concave cam and the first elastic member are both mounted on the first rotating shaft. The concave cam is located between the second gear and the first elastic member. The first end of the concave cam and the first elastic member together constitute the first end of the torque member. The second end of the concave cam is mounted on the second rotating shaft. The second end of the concave cam constitutes the second end of the torque member. One end of the first elastic member abuts the concave cam, and the other end abuts the base. The concave cam is pressed against the second gear by the action of the first elastic member. Thus, through this arrangement, the first elastic member can apply positive pressure to the concave cam, so that when the second gear rotates relative to the concave cam, a large friction force is generated, thereby providing torque for the support frame to rotate relative to the base.

[0065] In one possible implementation, the torque member further includes a second elastic member. The second elastic member is located on the side of the concave cam facing away from the third gear and is sleeved onto the second rotating shaft. The second end of the concave cam and the second elastic member together constitute the second end of the torque member. One end of the second elastic member abuts the concave cam, and the other end abuts the base. The concave cam, under the action of the second elastic member, compresses the third gear. This arrangement allows the second elastic member to apply positive pressure to the concave cam, generating a significant frictional force when the third gear rotates relative to the concave cam, thereby providing torque for the support frame to rotate relative to the base.

[0066] In one possible implementation, the concave cam includes a first side surface and a second side surface disposed opposite to each other, the first side surface facing the second gear, a first groove being provided at the first end of the concave cam, an opening of the first groove being formed at the first side surface, and the first rotating member further includes a first protrusion fixedly connected to the surface of the second gear facing the concave cam. When the support frame rotates relative to the base, the first protrusion can slide into or out of the first groove. In this way, under the action of the first elastic member, through the cooperation between the first protrusion and the first groove, the torsion structure can provide torque to the rotation mechanism at the center axis of the first rotating member when the support frame is opened to a specific angle relative to the base, thereby meeting the user's usage requirements.

[0067] In one possible implementation, the support body includes a first side portion, a middle portion and a second side portion, the middle portion is fixedly connected between the first side portion and the second side portion, the base is located between the first side portion and the second side portion, and is rotatably connected to the first side portion and the second side portion, and the transmission member is fixedly connected to the middle portion and is located in the inner space of the base.

[0068] It is understandable that, compared to the case where the support frame is located on the inner side of the base, the support frame needs to be provided with an additional avoidance space to avoid the first rotating member and the second rotating member installed on the base. This makes the structural strength of the support frame itself lower and is prone to breakage when overloaded. The base in this embodiment can be located between the first side portion and the second side portion of the support frame, that is, the base can be located on the inner side of the support frame. In this way, the first rotating member and the second rotating member will not interfere with the support frame, and the support frame does not need to be provided with an additional avoidance space to avoid the first rotating member and the second rotating member, which is beneficial to improving the structural strength of the support frame and extending the service life of the rotating mechanism.

[0069] In an eighth aspect, a housing device is provided, comprising a housing body, a support member, and the aforementioned rotation mechanism, wherein the base is fixedly connected to the housing body, the support member is fixedly connected to the support member, and the support member can be opened or closed relative to the housing body under the action of the rotation mechanism.

[0070] In a ninth aspect, an electronic device is provided, comprising a screen and the aforementioned housing device, wherein the screen is located on a side of the housing body facing away from the support member and is mounted on the housing body. BRIEF DESCRIPTION OF THE DRAWINGS

[0216] The embodiments of the present application are described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0217] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "inside", "outside", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. "Multiple" means at least two.

[0218] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.

[0219] In the embodiments of this application, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0220] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in some other embodiments," and "in another embodiment" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0221] It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0222] Figure 1It is a structural diagram of the electronic device 1 provided in an embodiment of the present application when the rotating mechanism 100 is in a closed state. Figure 2 yes Figure 1 The structure diagram of the electronic device 1 shown is when the rotating mechanism 100 is in the open state. Figure 3 yes Figure 1 The illustrated schematic diagram is an exploded structural diagram of the housing device 10 of the electronic device 1 in some embodiments.

[0223] like Figures 1 to 3 As shown, the electronic device 1 may include a shell device 10 and a screen 20. The screen 20 may be mounted on the shell device 10. The shell device 10 may have an open state and a closed state. When the shell device 10 is in a closed state, the electronic device 1 may be placed flat on a support table (not shown) for user use. Alternatively, the user may also hold the electronic device 1 for use. When the shell device 10 is in an open state, a portion of the shell device 10 may be set at an angle to the screen 20 and supported on the support table 2. At this time, the screen 20 of the electronic device 1 may be set at an angle to the support table 2 for user use. It should be noted that the support table 2 may be a physical structure such as a table or a booth, or it may be a part of the human body such as a hand or a leg, or it may be other virtual structures. It is understandable that the support table 2 may be a plane, a curved surface or other shapes, and this application does not limit this. It should be understood that, Figure 1 The dotted line schematically illustrates the obscured rotation mechanism 100 located within the housing device 10. For ease of description, the thickness direction of the electronic device 1 is defined as the Z-axis, which serves as the first direction Z. The length direction of the electronic device 1 is defined as the X-axis, which serves as the second direction X. The width direction of the electronic device 1 is defined as the Y-axis, which serves as the third direction Y. It will be appreciated that the coordinate system of the electronic device 1 can be flexibly configured based on specific practical needs.

[0224] Exemplarily, the housing device 10 may include a rotating mechanism 100, a housing body 200, and a support member 310. The screen 20 may be mounted on the housing body 200. The support member 310 may be located on the side of the housing body 200 facing away from the screen 20, that is, the non-display side of the housing body 200. The rotating mechanism 100 may include a base 110 and a support frame 120. The base 110 of the rotating mechanism 100 may be fixedly connected to the housing body 200. The support frame 120 of the rotating mechanism 100 may be fixedly connected to the support member 310. The base 110 and the support frame 120 of the rotating mechanism 100 may rotate relative to each other so that the support member 310 can be opened or closed relative to the housing body 200. The rotating mechanism 100 may also be used to provide torsional force to the bracket so that the bracket can maintain a certain opening and closing angle relative to the device body and support the device body to meet user usage requirements.

[0225] Exemplarily, the support member 310 may include a connecting end 310a and a supporting end 310b disposed opposite to each other. The connecting end 310a of the support member 310 may be used to connect to the support frame 120 of the rotating mechanism 100. The supporting end 310b of the support member 310 may be used for a user to apply force to rotate relative to the connecting end 310a. When the housing device 10 is in a closed state, that is, when the rotating mechanism 100 is in a closed state, the support member 310 may be closed relative to the housing body 200. In this case, the appearance of the housing device 10 is relatively flat and beautiful. When the housing device 10 is in an open state, that is, when the rotating mechanism 100 is in an open state, the supporting end 310b of the support member 310 may be rotated relative to the connecting end 310a, and the support member 310 may be opened to a certain angle relative to the housing body 200. The rotating mechanism 100 can provide torsional force to the support member 310, so that the support member 310 can maintain a certain opening and closing angle with the housing body 200 to meet the user's usage requirements. At this time, the supporting end 310 b of the supporting member 310 may contact the supporting platform to support the entire electronic device 1 .

[0226] In some embodiments, the housing body 200 may further include a receiving slot 210. At least a portion of the rotating mechanism 100 may be located within the receiving slot 210. The housing device 10 may further include a back cover 320. The back cover 320 may be fixedly attached to the surface of the housing body 200 facing away from the screen 20 by bonding, screwing, or other means. The back cover 320 may cover a portion of the opening of the receiving slot 210. The support member 310 may cover another portion of the opening of the receiving slot 210. Thus, providing the receiving slot 210 to accommodate at least a portion of the rotating mechanism 100 allows the rotating mechanism 100 to utilize the thickness of the housing body 200, facilitating a thinner design for the entire electronic device 1. This also enhances the appearance of the housing device 10, resulting in a smoother and more aesthetically pleasing surface. In other embodiments, the housing device 10 may not include the back cover 320. The support member 310 may completely cover the opening of the receiving slot 210. In other embodiments, the back cover 320 may be integrally formed with the housing body 200.

[0227] In some embodiments, the electronic device 1 may include, but is not limited to, a two-in-one product, an all-in-one computer, and a mobile phone. A two-in-one product typically includes a main unit and a keyboard assembly, wherein the main unit and the keyboard assembly are detachably connected. After the main unit is separated from the keyboard assembly, the main unit can still be used as an independent electronic device 1, such as a tablet computer.

[0228] In some embodiments, the electronic device 1 can also be a foldable electronic device 1, such as a foldable mobile phone, a foldable tablet computer, etc. For example, the electronic device 1 can have a two-fold structure. The housing body 200 can include a first housing (not shown), a second housing (not shown), and a rotating shaft (not shown). The rotating shaft can connect the first housing and the second housing. Rotation can cause movement so that the first housing and the second housing can be relatively opened to a flat state, and can also cause the first housing and the second housing to be relatively folded to a closed state. The support member 310 and the rotating mechanism 100 can connect one of the first housing and the second housing. In some other embodiments, the electronic device 1 can also have a structure that folds three or more times, that is, the electronic device 1 can include three or more flat plate parts. Two adjacent flat plate parts are connected by a bent portion, and the two adjacent flat plates can be rotated relative to each other to overlap each other or rotated away from each other to flatten. When the electronic device 1 has a structure that folds three or more times, the structure of the electronic device 1 can be adaptively designed with reference to the description of the two-fold structure above, and will not be repeated here.

[0229] In some embodiments, the shell device 10 can also serve as a protective shell independent of the electronic device 1. In this case, the electronic device 1 may include a screen 20 and a device shell (not shown). The screen 20 and the shell device 10 can be installed on opposite sides of the device shell, respectively. The shell device 10 can be removed from the device shell. In this way, on the one hand, the shell device 10 can be used to protect the device shell of the electronic device 1. On the other hand, when the shell device 10 is damaged, the shell device 10 is detachably connected to the device shell, so that the shell device 10 is easy to replace and repair, and the maintenance cost is low. In some other embodiments, the rotating mechanism 100 can also be applied to other structural parts or products that require support.

[0230] It is understandable that the support frame of a general rotating mechanism is usually fixed to the support member by means of screw locking. The base of the rotating mechanism is also usually fixed to the shell body by means of screw attachment. This requires the user to open the rotating mechanism to a larger opening and closing angle during the process of disassembling the rotating mechanism, and then use tools to remove the screws to disassemble the rotating mechanism. The disassembly process of the rotating mechanism is relatively cumbersome, and it is difficult for the user to quickly disassemble the rotating mechanism, resulting in a poor user experience. The rotating mechanism 100 in the embodiment of the present application improves the connection method between the rotating mechanism 100 and the support member 310 and / or the connection method between the rotating mechanism 100 and the shell body 200, so that the user can quickly disassemble the rotating mechanism 100, thereby improving the user experience.

[0231] Several types of rotating mechanisms 100 that are convenient for users to quickly disassemble will be described in detail below with reference to the relevant drawings.

[0232] First embodiment: Figure 4 yes Figure 3The illustrated structure diagram of the rotating mechanism 100 in the first embodiment is in a closed state. Figure 5 yes Figure 3 The illustrated structure diagram of the rotating mechanism 100 in the first embodiment is in the open state. Figure 6 yes Figure 4 The illustrated diagram is a schematic exploded view of the rotating mechanism 100 in some embodiments.

[0233] like Figures 4 to 6 As shown, the rotating mechanism 100 can include an open state and a closed state. The rotating mechanism 100 may include a base 110, a support frame 120, a torsion structure 130, a tongue 140, and an elastic block 150. The support frame 120 can be rotatably connected to the base 110. The torsion structure 130 can connect the base 110 and the support frame 120. The torsion structure 130 can be used to provide torsion when the support frame 120 rotates relative to the base 110. Among them, the base 110 may include a first rotating body. The support frame 120 may include a second rotating body. The first rotating body of the base 110 can cooperate with the second rotating body of the support frame 120 to enable the support frame 120 to rotate relative to the base 110, thereby enabling the rotating mechanism 100 to switch between the open state and the closed state.

[0234] Figure 7 yes Figure 6 The structure diagram of the base 110 and the inserting tongue 140 shown in another perspective. Figure 8 yes Figure 4 The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the rotating mechanism 100 cut along A1 - A1 . Figure 9 yes Figure 4 The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the rotating mechanism 100 cut along A2 - A2 .

[0235] like Figures 7 to 9As shown, the base 110 may include a top surface and a bottom surface disposed opposite to each other along a first direction Z, and a peripheral side surface connected between the top surface and the bottom surface. For ease of understanding, in this embodiment, the top surface, bottom surface, and peripheral side surface of the base 110 are respectively named as the first top surface 111, the first bottom surface 112, and the first peripheral side surface 113. The base 110 may have a generally frame-shaped structure. The base 110 may include a first branch 114, a second branch 115, a third branch 116, and a fourth branch 117 connected end to end. The first branch 114, the second branch 115, the third branch 116, and the fourth branch 117 may enclose an inner space 110a of the base 110. The first branch 114 may be disposed opposite the third branch 116. The first branch 114 and the third branch 116 may be arranged in the second direction X. The second branch 115 may be disposed opposite the fourth branch 117. The second branch 115 and the fourth branch 117 may be arranged in the third direction Y. The second branch 115 and the fourth branch 117 may be connected between the first branch 114 and the third branch 116 .

[0236] Exemplarily, the first peripheral side surface 113 may include a first outer side surface 1131 and a second outer side surface 1132. The orientations of the first outer side surface 1131 and the second outer side surface 1132 may be different. Specifically, the first outer side surface 1131 may be formed by at least a portion of the surface of the third branch 116 facing away from the first branch 114. The second outer side surface 1132 may be formed by at least a portion of the surface of the fourth branch 117 facing away from the second branch 115. In other embodiments, the second outer side surface 1132 may also be formed by at least a portion of the surface of the first branch 114 facing away from the third branch 116. Alternatively, the second outer side surface 1132 may also be formed by at least a portion of the surface of the second branch 115 facing away from the fourth branch 117.

[0237] Illustratively, the tongue 140 can be fixedly connected to the first outer side surface 1131. The extension direction of the tongue 140 can be parallel to the first bottom surface 112. The extension direction of the tongue 140 can be understood as the length extension direction or the width extension direction of the tongue 140. Illustratively, the thickness of the tongue 140 can be less than the thickness of the base 110. In this embodiment, there can be two tongues 140. Both tongues 140 can be fixedly connected to the first outer side surface 1131 of the base 110. In other embodiments, the number of tongues 140 can be other. This application does not specifically limit this.

[0238] For example, the first branch 114 may be provided with a first connecting hole 1141 and a second connecting hole 1142. The first connecting hole 1141 may extend through the second outer side surface 1132 of the base 110. The second connecting hole 1142 may extend through the first top surface 111 of the base 110. The first branch 114 may have a receiving space 1143. The receiving space 1143 may be spaced apart from the inner space 110a of the base 110. The receiving space 1143 may connect the first connecting hole 1141 and the second connecting hole 1142. The first connecting hole 1141 and the second connecting hole 1142 may both partially expose a portion of the receiving space 1143. The receiving space 1143 may include a first surface 1143a and a second surface 1143b disposed opposite each other. The first surface 1143a may be located between the first connecting hole 1141 and the second surface 1143b. The length of the first connecting hole 1141 may extend parallel to the direction from the first surface 1143a to the second surface 1143b. For example, the direction from the first surface 1143a to the second surface 1143b can be parallel to the direction from the second branch 115 to the fourth branch 117 (also known as the third direction Y in this embodiment). The second connecting hole 1142 can be substantially strip-shaped. The length of the second connecting hole 1142 can extend perpendicular to the first direction Z.

[0239] For example, the second branch 115 may include a first inner side surface 1151 disposed toward the fourth branch 117. The base 110 may further include a first protrusion 1152. The first protrusion 1152 may be fixed to the first inner side surface 1151. The first protrusion 1152 may be in the shape of an arc. The first protrusion 1152 may be disposed closer to the third branch 116 than the first branch 114.

[0240] Exemplarily, the fourth branch 117 may include a second inner side surface 1171 disposed toward the second branch 115. That is, the second inner side surface 1171 may be disposed opposite the first inner side surface 1151. The base 110 may further include a second protrusion 1172. The second protrusion 1172 may be fixed to the second inner side surface 1171. The shape of the second protrusion 1172 may be arc-shaped. The second protrusion 1172 may be disposed directly opposite the first protrusion 1152. The shape and size of the second protrusion 1172 and the first protrusion 1152 may be identical. In this case, the first protrusion 1152 and the second protrusion 1172 may together constitute the first rotating body of the base 110.

[0241] In some embodiments, the base 110 may include a first sub-base (not shown) and a second sub-base (not shown). The first sub-base and the second sub-base may be roughly bilaterally symmetrical structures. The first sub-base may be fixedly connected to the second sub-base by screwing, welding, etc. Part of the first sub-base and part of the second sub-base may jointly enclose a receiving space 1143. Exemplarily, the first sub-base may include a portion of the first branch 114, the second branch 115, and a portion of the third branch 116. The second sub-base may include another portion of the first branch 114, the fourth branch 117, and another portion of the third branch 116. In this way, by dividing the base 110 into a first sub-base and a second sub-base that are independent of each other, the base 110 is easy to prepare, and the base 110 is also easy to assemble with other components of the rotating mechanism 100.

[0242] Figure 10 yes Figure 6 FIG. 1 is a schematic structural diagram of the elastic block 150 of the rotating mechanism 100 .

[0243] like Figure 10 As shown, the elastic block 150 may include a mounting slider 150a and an elastic element 150b. The mounting slider 150a may include a main body 151, a first protrusion 152, and a second protrusion 153. The main body 151 may include a top surface and a bottom surface disposed opposite each other along a first direction Z, as well as a peripheral side surface connected between the top and bottom surfaces. For ease of understanding, the top surface, bottom surface, and peripheral side surface of the main body 151 may be designated as a second top surface 1511, a second bottom surface 1512, and a second top surface 1511, a second bottom surface 1512, and a second peripheral side surface 1513. The second protrusion 153 may be fixedly connected to the second top surface 1511 of the main body 151. The first protrusion 152 may be fixedly connected to the second peripheral side surface 1513 of the main body 151. One end of the elastic element 150b may be connected to the surface of the main body 151 facing away from the first protrusion 152. For example, the elastic element 150b may be a coil spring.

[0244] In some embodiments, the surface of the main body 151 facing away from the first protrusion 152 may be partially recessed inward to form a groove 1514. A portion of the elastic element 150b may be located within the groove 1514 of the main body 151. Thus, by providing the groove 1514 in the main body 151 to limit the elastic element 150b, it helps prevent the elastic element 150b from slipping against the main body 151 during movement. Furthermore, the elastic element 150b can utilize the space provided by the main body 151, ensuring a certain length and elastic force while maintaining a relatively small overall size relative to the mounting slider 150a.

[0245] Figure 11 yes Figure 6FIG. 1 is a schematic diagram of a partial structural assembly of the rotating mechanism 100 . Figure 12 yes Figure 4 The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the rotating mechanism 100 cut along A1 - A1 . Figure 13 yes Figure 4 The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the rotating mechanism 100 cut along A2 - A2 .

[0246] like Figures 11 to 13 As shown, the main body 151 of the mounting slider 150a can be disposed in the receiving space 1143 of the first branch 114 of the base 110. The first protrusion 152 of the mounting slider 150a can be inserted into the first connecting hole 1141. The second protrusion 153 of the mounting slider 150a can be inserted into the second connecting hole 1142. A portion of the second protrusion 153 of the mounting slider 150a can be positioned in the second connecting hole 1142, while another portion of the second protrusion 153 can be exposed relative to the second connecting hole 1142.

[0247] For example, the elastic element 150b can be disposed in the receiving space 1143 of the first branch 114. One end of the elastic element 150b can abut the surface of the main body 151 facing away from the first protrusion 152, while the other end of the elastic element 150b can abut the second surface 1143b of the receiving space 1143, that is, abut the first branch 114. At this time, the surface of the main body 151 facing the first protrusion 152 can, under the action of the elastic element 150b, press the first surface 1143a of the receiving space 1143, that is, press the first branch 114. A portion of the first protrusion 152 of the mounting slider 150a can be located within the first connecting hole 1141, while another portion of the first protrusion 152 can be exposed relative to the first connecting hole 1141, that is, another portion of the first protrusion 152 can protrude relative to the second outer side surface 1132 of the base 110.

[0248] Figure 14 yes Figure 12 The structure shown is a schematic cross-sectional view of the structure when the surface of the main body portion 151 of the mounting slider 150 a facing away from the first protrusion 152 contacts the second surface 1143 b of the receiving space 1143 . Figure 15 yes Figure 13 The structure shown is a schematic cross-sectional view of the structure when the surface of the main body portion 151 of the mounting slider 150 a facing away from the first protrusion 152 contacts the second surface 1143 b of the receiving space 1143 .

[0249] like Figure 14 and Figure 15As shown, the second protrusion 153 of the mounting slider 150a can slide within the second connecting hole 1142 under the action of an external force. For example, the mounting slider 150a can slide in a direction approaching the second surface 1143b under the action of an external force. At this time, the main body 151 can slide within the receiving space 1143, driven by the second protrusion 153, and compress the elastic element 150b. The first protrusion 152 can slide along the lengthwise direction of the first connecting hole 1141 (also known as the third direction Y in this embodiment), driven by the second protrusion 153, and gradually slide into the receiving space 1143. When the second protrusion 153 slides in a direction approaching the second surface 1143b until the surface of the main body 151 facing away from the first protrusion 152 contacts the wall of the receiving space 1143 (also known as the second surface 1143b), a portion of the first protrusion 152 can be located within the first connecting hole 1141, and the remaining portion of the first protrusion 152 can be located within the receiving space 1143. That is, the first protrusion 152 can be completely received in the first branch portion 114 , and the first protrusion 152 can be retracted relative to the second outer surface 1132 .

[0250] Figure 16 yes Figure 6 The structure diagram of the support frame 120 shown in another perspective.

[0251] like Figure 6 and Figure 16 As shown, the support frame 120 may include a first side surface 121 and a second side surface 122 disposed opposite to each other. The support frame 120 may be provided with a first sliding groove 123 and a second sliding groove 124. The opening of the first sliding groove 123 may be formed on the first side surface 121 of the support frame 120. The opening of the second sliding groove 124 may be formed on the second side surface 122 of the support frame 120. That is, the opening of the first sliding groove 123 and the opening of the second sliding groove 124 may be disposed opposite to each other. The shape and size of the first sliding groove 123 and the second sliding groove 124 may be the same. The first sliding groove 123 and the second sliding groove 124 may both be arc-shaped grooves. At this time, the first sliding groove 123 and the second sliding groove 124 may together constitute the second rotating body of the support frame 120.

[0252] Figure 17 yes Figure 4 The cross-sectional structure diagram of the rotating mechanism 100 in one embodiment is shown along A3-A3. Figure 18 yes Figure 5 The illustrated diagram is a cross-sectional structural diagram of an embodiment of the rotating mechanism 100 cut along A4-A4. Figure 19 yes Figure 4 The illustrated diagram is a cross-sectional structural diagram of an embodiment of the rotating mechanism 100 taken along A5-A5.

[0253] like Figures 17 to 19 As shown, at least a portion of the support frame 120 can be accommodated within the inner space 110a of the base 110. The first protrusion 1152 of the base 110 can engage with the first sliding groove 123 of the support frame 120. The second protrusion 1172 of the base 110 can engage with the second sliding groove 124 of the support frame 120. In other words, the second rotating member of the support frame 120 can engage with the first rotating member of the base 110, allowing the support frame 120 to be rotatably connected to the base 110 and rotate relative to the base 110. When the rotation mechanism 100 switches between the closed and open states, the first protrusion 1152 of the support frame 120 can slide relative to the first sliding groove 123 of the base 110. The second protrusion 1172 of the support frame 120 can slide relative to the second sliding groove 124 of the base 110. At this time, the support frame 120 can rotate relative to the base 110 about a first axis (not shown). The first axis can be a virtual axis (in this embodiment, the line connecting the centers of the first sliding slot 123 and the second sliding slot 124) and is spaced apart from the rotation mechanism 100. In other embodiments, the support frame 120 can also be rotatably connected to the base 110 via a physical rotation axis. In this case, the first axis can be the axis center of the physical rotation axis. The first axis can pass through the rotation mechanism 100.

[0254] In some embodiments, please refer to Figures 17 to 19 , and combined with Figure 6 As shown, the torsion structure 130 may include a first rotating member 131, a second rotating member 132, and a torsion member 133. The first rotating member 131 may be fixed to the support frame 120. The first rotating member 131 may be slidably connected to the base 110. The torsion member 133 may include a first end 1331 and a second end 1332. The first end 1331 of the torsion member 133 may be provided with a first through hole 1331a and be mounted on the first rotating member 131. The torsion member 133 is capable of rotating relative to the first rotating member 131. The second end 1332 of the torsion member 133 may be provided with a second through hole 1332a and be mounted on the second rotating member 132. The torsion member 133 is capable of rotating relative to the second rotating member 132. The first end 1331 of the torsion member 133 may be in an interference fit with the first rotating member 131. The second end 1332 of the torsion member 133 may be in an interference fit with the second rotating member 132. For example, the first rotating member 131 and the second rotating member 132 may both be shaft-like structures, such as rotating shafts. The torsion member 133 may be an elastically wrapped circle.

[0255] Interference fit refers to an interference fit or other fit that can generate torque or friction. Taking the first end 1331 of the torsion member 133 and the first rotating member 131 as an example, when the first end 1331 and the first rotating member 131 are in interference fit, relative rotation between the first end 1331 and the first rotating member 131 can still occur, but the first end 1331 needs to apply a force to the support frame 120 when rotating relative to the first rotating member 131. When the support frame 120 is not subjected to a force, the interference fit between the first end 1331 and the first rotating member 131 provides torque, allowing the two to maintain their current posture, so that the support frame 120 can maintain the current opening and closing angle relative to the base 110. Thus, by fixing the first rotating member 131 to the support frame 120, slidably connecting the second rotating member 132 to the base 110, and providing a torque member 133 with its two ends respectively sleeved on the first rotating member 131 and the second rotating member 132, and with its two ends respectively interfering with the first rotating member 131 and the second rotating member 132, when the rotating mechanism 100 switches between the open state and the closed state, the torque member 133 can cooperate with the first rotating member 131 and the second rotating member 132 to provide torque for the rotating mechanism 100. It should be understood that the interference fit mentioned below can be adaptively understood with reference to the above description and will not be described in detail later.

[0256] In some embodiments, the inner circumferential side wall of the first through hole 1331a may further be provided with a first flattened position (not shown). The outer circumferential side wall of the first rotating member 131 may further be provided with a second flattened position (not shown). In this way, when the first rotating member 131 rotates relative to the first through hole 1331a to the first flattened position facing the second flattened position, under the elastic action of the first end 1331 itself, the first flattened position may be close to the second flattened position, thereby achieving self-locking of the first rotating member 131 and the first through hole 1331a. In other embodiments, the inner circumferential side wall of the second through hole 1332a may further be provided with a third flattened position (not shown). The outer circumferential side wall of the second rotating member 132 may further be provided with a fourth flattened position (not shown). In this way, through the cooperation of the third flattened position and the fourth flattened position, the self-locking of the second rotating member 132 and the second through hole 1332a can also be achieved.

[0257] In some embodiments, the torsion structure 130 may further include a reinforcement member 134. The reinforcement member 134 may be fixedly connected to the portion between the first end 1331 and the second end 1332 of the torsion member 133 to provide structural reinforcement to this portion of the torsion member 133 and enhance the overall structural strength of the torsion member 133. Thus, the reinforcement member 134 can prevent the torsion member 133 from being subjected to large torsional forces at the first end 1331 and / or the second end 1332, which could lead to fracture of the portion between the first end 1331 and the second end 1332, thereby extending the service life of the torsion member 133.

[0258] In other embodiments, the torsion structure 130 may also be in other forms capable of providing torsion for the relative rotation between the support frame 120 and the base 110 .

[0259] Figure 20a yes Figure 3 The structure diagram of the housing body 200 of the housing device 10 shown is shown in another perspective. Figure 20b yes Figure 3 The structure diagram of the housing body 200 of the housing device 10 shown is shown at another viewing angle.

[0260] like Figure 20a and Figure 20b As shown, the shell body 200 may be provided with a receiving groove 210. The receiving groove 210 may include a groove bottom surface 211 and a groove side surface 212 connecting the periphery of the groove bottom surface 211. The shell body 200 may also be provided with an undercut structure 213. The undercut structure 213 may include a first part 2131 and a second part 2132. The first part 2131 may be fixedly connected to the end of the second part 2132 and be arranged at an angle to the second part 2132, for example, at a 90° angle. At this time, the undercut structure 213 may be roughly "L"-shaped. It should be understood that Figure 20a and Figure 20b In the figure, the first part 2131 and the second part 2132 of the undercut structure 213 are schematically divided by dotted lines.

[0261] Illustratively, the first portion 2131 of the undercut structure 213 can be fixedly connected to the bottom surface 211 of the receiving groove 210. The second portion 2132 can be spaced apart from the bottom surface 211 of the receiving groove 210, and a first limiting groove 210a is formed between the undercut structure 213 and the bottom surface 211. In this embodiment, the number of undercut structures 213 can be two. In other embodiments, the number of undercut structures 213 can also be other. This application does not make specific restrictions on this. In some other embodiments, the shell body 200 may also not include the undercut structure 213. The first limiting groove 210a can also be directly formed on the groove side 212 of the receiving groove 210.

[0262] For example, the housing body 200 may further include a second limiting groove 210b. The opening of the second limiting groove 210b may be formed on a groove side surface 212 of the receiving groove 210. The second limiting groove 210b may include a first surface 214 and a second surface 215 disposed opposite each other. The first surface 214 and the second surface 215 may be spaced apart along the first direction Z. The first surface 214 may be disposed further away from the groove bottom surface 211 of the receiving groove 210 than the second surface 215.

[0263] Figure 21 yes Figure 2The shown schematic diagram is a cross-sectional structural diagram of an embodiment of the housing device 10 taken along A6-A6. Figure 22 yes Figure 2 The shown schematic diagram is a cross-sectional structural diagram of an embodiment of the housing device 10 taken along A7-A7. Figure 23 yes Figure 22 The structure shown is a schematic cross-sectional view of the structure when the first protrusion 152 of the mounting slide 150a slides out of the second limiting groove 210b.

[0264] like Figures 21 to 23 As shown, the support frame 120 can be fixedly connected to the support member 310 by screwing or other means. At least a portion of the tongue 140 can be inserted into the first retaining groove 210a between the second portion 2132 of the undercut structure 213 and the groove bottom surface 211. In this case, the second portion 2132 of the undercut structure 213 and at least a portion of the tongue 140 can be stacked in the first direction Z. The tongue 140 can abut the second portion 2132 of the undercut structure 213. The second portion 2132 of the undercut structure 213 can limit the tongue 140 from above.

[0265] For example, under the action of the elastic element 150b, a portion of the first protrusion 152 of the mounting slider 150a can be exposed relative to the first communication hole 1141 of the first branch 114 of the base 110 and accommodated in the second retaining groove 210b of the housing body 200. The first protrusion 152 can abut against the first surface 214 and the second surface 215 of the second retaining groove 210b. The first surface 214 of the second retaining groove 210b can exert a downward force on the first protrusion 152. The first surface 214 of the second retaining groove 210b can retain the first protrusion 152 from above, thereby retaining the first branch 114 of the base 110. In this way, the first limiting groove 210a and the second limiting groove 210b of the housing body 200 can respectively limit the insertion tongue 140 and the elastic block 150 of the rotating mechanism 100, thereby limiting the first branch 114 and the third branch 116 of the base 110, so as to fix the base 110 to the housing body 200. In other words, the base 110 can be fixed to the housing body 200 by the insertion tongue 140 and the elastic block 150.

[0266] For example, when the user needs to disassemble the rotating mechanism 100, the user only needs to open the support frame 120 relative to the base 110 at a small angle to expose the first branch 114 of the base 110. The user can then slide the second protrusion 153 of the mounting slider 150a in a direction close to the second surface 1143b of the receiving space 1143 (it should be understood that Figure 13 and Figure 15The movement of the second protrusion 153 within the second connecting hole 1142 is also illustrated from another perspective), thereby enabling the installation slider 150a to slide relative to the receiving space 1143 of the first branch 114. At this time, the first protrusion 152 of the installation slider 150a can gradually slide into the base 110 and gradually slide out of the second limiting groove 210b of the shell body 200. When the first protrusion 152 completely slides out of the second limiting groove 210b, the user can operate the first branch 114 of the base 110 to disengage from the shell body 200. Then, the user disengages the tongue 140 from the undercut structure 213 to achieve the disengagement of the entire base 110 from the shell body 200, completing the disassembly of the base 110 from the shell body 200. Subsequently, the user can disengage the support frame 120 from the support member 310 as needed to complete the disassembly of the entire rotating mechanism 100. In some embodiments, the surface of the base 110 facing away from the first limiting groove 210a can be spaced apart from and opposite to the side surface 212 of a portion of the receiving groove 210. Thus, the base 110 can be moved backward in a direction away from the first limiting groove 210a to allow the tongue 140 to exit the first limiting groove 210a, thereby unlocking the tongue 140 from the first limiting groove 210a.

[0267] For example, the projection of the support member 310 on the groove bottom surface 211 can at least partially overlap with the projection of the elastic block 150 on the groove bottom surface 211. The projection of the back cover 320 on the groove bottom surface 211 can at least partially overlap with the projection of the tongue 140 on the groove bottom surface 211. In this way, when the rotating mechanism 100 needs to be disassembled from the housing body 200, the user does not need to remove the back cover 320. Instead, the user only needs to remove the tongue 140 from the first limiting groove 210a and the elastic block 150 from the second limiting groove 210b to disengage the rotating mechanism 100 from the housing body 200, making disassembly more convenient and quick.

[0268] It is understandable that, compared to conventional rotation mechanisms, which require screws to be locked to the housing body at at least two locations on the base, when the user needs to disassemble the rotation mechanism, they need to open the support frame relative to the base to a larger opening and closing angle, and then use tools to remove multiple screws to remove the entire rotation mechanism from the housing body. This user disassembly process is relatively cumbersome, takes a long time, and provides a poor user experience. In this embodiment, a first limiting groove 210a and a second limiting groove 210b are provided in the housing body 200. The tongue 140 of the rotation mechanism 100 is inserted into the first limiting groove 210a, and the elastic block 150 of the rotation mechanism 100 is snapped into the second limiting groove 210b. In this way, the base 110 can be fixed to the housing body 200 by engaging the tongue 140 in the first limiting groove 210a, and the second limiting groove 210b with the elastic block 150. Thus, when the user needs to remove the rotating mechanism 100 from the housing body 200, they only need to control the elastic block 150 to retract relative to the base 110 to unlock the elastic block 150 and the second limiting groove 210b. Then, by pulling the tongue 140 out of the first limiting groove 210a, the base 110 can be completely separated from the housing body 200, thereby completing the removal of the entire rotating mechanism 100. The disassembly method of the rotating mechanism 100 and the housing body 200 of this embodiment is simpler to operate, takes less time to disassemble, and provides a better user experience.

[0269] Secondly, the elastic block 150 in this embodiment includes a mounting slider 150a and an elastic element 150b. The elastic force of the elastic element 150b is used to hold a portion of the mounting slider 150a against the second limiting groove 210b. When the user needs to remove the rotating mechanism 100 from the housing body 200, they only need to slide the mounting slider 150a so that the portion of the mounting slider 150a located in the second limiting groove 210b slides out of the second limiting groove 210b, thereby disengaging the second fixing portion from the housing body 200. Then, the first fixing portion is pulled out from the inner side of the undercut structure 213, and the entire rotating mechanism 100 is removed from the housing body 200. The entire disassembly process does not require the use of tools, making it simple and convenient. At the same time, the user only needs to open the rotating mechanism 100 to a small angle to expose the mounting slider 150a, and then unlock it by sliding the mounting slider 150a. In other words, the rotating mechanism 100 of this embodiment can achieve rapid disassembly of the rotating mechanism 100 and the housing body 200 at a relatively small opening and closing angle, and the user experience is better.

[0270] In some embodiments, the first surface 214 and the second surface 215 of the second limiting groove 210b can be arranged at an angle. The distance between the first surface 214 and the second surface 215 of the second limiting groove 210b can gradually increase in the direction approaching the receiving groove 210. In this way, when the first protrusion 152 of the mounting slider 150a slides into the second limiting groove 210b of the housing body 200, the first protrusion 152 can cooperate with the first surface 214 and the second surface 215 of the second limiting groove 210b and squeeze each other. The force exerted by the first surface 214 and / or the second surface 215 on the first protrusion 152 can intersect with the first direction Z, so that the second limiting groove 210b can better limit the first protrusion 152, preventing the first protrusion 152 from shaking within the second limiting groove 210b, thereby preventing the rotating mechanism 100 from shaking and affecting the user experience. In this embodiment, the first surface 214 can be used to be perpendicular to the first direction Z.

[0271] In some embodiments, please refer again to Figure 21 , the shell body 200 may further include a fulcrum 216. The fulcrum 216 may be provided in the receiving groove 210 and fixedly connected to the groove bottom surface 211 of the receiving groove 210. The fulcrum 216 may be located between the first limiting groove 210a and the second limiting groove 210b. In this embodiment, the fulcrum 216 may be located between the undercut structure 213 and the mounting slider 150a. For example, the fulcrum 216 may be roughly fan-shaped. The number of fulcrums 216 may be two. When the base 110 is mounted on the shell body 200, the two fulcrums 216 may respectively abut the second branch 115 and the fourth branch 117 of the base 110 and apply an upward force (in this embodiment, that is, in the positive direction of the Z axis) to the base 110. At this time, the contact portion of the fulcrum 216 with the base 110 may be located between the first fixed portion and the second fixed portion of the base 110. For example, the second branch 115 and / or the fourth branch 117 may further include a mating groove 110c. In this embodiment, both the second branch 115 and the fourth branch 117 may include a mating groove 110c. The shape of the mating groove 110c may match the shape of the fulcrum 216. When the base 110 is mounted on the housing body 200, a portion of the fulcrum 216 may be located within the mating groove 110c. The fulcrum 216 may abut the groove wall of the mating groove 110c and prop up the base 110.

[0272] It is understood that when the base 110 is fixed to the housing body 200, the tongue 140 and the elastic block 150 can be subjected to a downward force (in this embodiment, the negative direction of the Z axis) under the action of the housing body 200. At this time, the fulcrum 216 can upwardly prop up a portion of the base 110 between the portion where the tongue 140 is fixedly connected and the portion where the elastic block 150 is mounted. In other words, the portion of the base 110 in contact with the fulcrum 216 can be located between the tongue 140 and the elastic block 150 and be subjected to an upward force (in this embodiment, the positive direction of the Z axis). In this way, by making the force directions of the two ends of the base 110 (i.e., the ends provided with the inserting tongue 140 and the elastic block 150) the same, and making the force direction of the portion of the base 110 located between the inserting tongue 140 and the elastic block 150 opposite to the force direction of the end of the base 110 provided with the inserting tongue 140, the base 110 can be fixed to the shell body 200 and locked with the shell body 200 to prevent the base 110 from shaking relative to the shell body 200.

[0273] Figure 24 yes Figure 21 The shown schematic diagram is a partial cross-sectional structure of the housing device 10 in another embodiment.

[0274] like Figure 24 As shown, the rotating mechanism 100 in this embodiment is Figure 21 The structure of the rotating mechanism 100 shown in FIG. 1 is substantially the same, and the same parts are not repeated here. Figure 21 Different features of the rotating mechanism 100 are shown.

[0275] For example, the housing body 200 may further include a mounting slot 210c. The opening of the mounting slot 210c may be formed on a side surface 212 of the receiving slot 210. The housing device 10 may further include an elastic stopper 220. The elastic stopper 220 may be mounted on the mounting slot 210c of the housing body 200. The elastic stopper 220 may partially extend from the receiving slot 210. In this case, a second stopper 210b may be formed between the elastic stopper 220 and the bottom surface 211 of the receiving slot 210. The elastic stopper 220 may also retract into the mounting slot 210c under the action of an external force to exit the receiving slot 210.

[0276] For example, the rotating mechanism 100 may not include an elastic block. The rotating mechanism 100 may also include a top block 160. The top block 160 may be fixedly connected to the second outer side surface 1132 of the base 110. At least a portion of the top block 160 may be inserted into the second limiting groove 210b and abut against the elastic limiting block 220. At this time, the elastic limiting block 220 may limit the top block 160. It should be understood that Figure 24The second outer side surface 1132 is indicated by a narrow dashed line.

[0277] Figure 25 yes Figure 21 The shown schematic diagram is a partial cross-sectional structure of the housing device 10 in another embodiment.

[0278] like Figure 25 As shown, the rotating mechanism 100 in this embodiment is Figure 21 The structure of the rotating mechanism 100 shown in FIG. 1 is substantially the same, and the same parts are not repeated here. Figure 21 Different features of the rotating mechanism 100 are shown.

[0279] For example, the rotating mechanism 100 may also not include an elastic block. The base 110 may be provided with a mounting hole 118. The mounting hole 118 may be spaced apart from the plug tongue 140. The housing device 10 may further include a fixing member 170. The fixing member 170 may be a screw, a bolt, etc. The fixing member 170 may pass through the mounting hole 118 of the base 110 to fix the base 110 to the housing body 200. The central axis Q1 of the mounting hole 118 may intersect with the plane where the housing body 200 is located (i.e., the XY plane in this embodiment). The angle formed by the central axis Q1 of the mounting hole 118 and the plane where the housing body 200 is located is a first angle α. The first angle α may be an acute angle, and the opening of the first angle α may face away from the plug tongue 140. Thus, by providing the mounting hole 118 on the base 110, and by forming an acute angle between the central axis Q1 of the mounting hole 118 and the plane on which the housing body 200 is located, with the opening of the angle facing away from the tongue 140, when the user needs to remove the rotating mechanism 100 from the housing body 200, they only need to open the rotating mechanism 100 by a small angle, and then use a tool to remove the screw (i.e., the fixing member 170) fixed to the mounting hole 118, thereby removing the entire rotating mechanism 100 from the housing body 200. The rotating mechanism 100 in this embodiment can achieve rapid disassembly of the rotating mechanism 100 and the housing body 200 even at a small opening and closing angle, providing a good user experience.

[0280] Second embodiment: Figure 26 4 is a structural diagram of a rotating mechanism 400 provided in the present application when in a closed state in the second embodiment. Figure 27 yes Figure 26 The illustrated structure diagram of the rotating mechanism 400 in the second embodiment is in an open state. Figure 28 yes Figure 27 The rotating mechanism 400 in some embodiments is shown as a schematic diagram of an exploded structure. For ease of understanding, the rotating mechanism 400 in this embodiment uses different reference numerals from the rotating mechanism 100 in the first embodiment.

[0281] like Figures 26 to 28 As shown, the rotation mechanism 400 can include an open state and a closed state. The rotation mechanism 400 may include a base 410, a support frame 420, a torsion structure 430 and a locking member 460. The support frame 420 can be rotatably connected to the base 410. The torsion structure 430 can connect the base 410 and the support frame 420. The torsion structure 430 can be used to provide torque when the support frame 420 rotates relative to the base 410. The base 410 may include a first rotating body. The support frame 420 may include a second rotating body. The first rotating body of the base 410 can cooperate with the second rotating body of the support frame 420 to enable the support frame 420 to rotate relative to the base 410, thereby enabling the rotation mechanism 400 to switch between the open state and the closed state. One of the first rotating body and the second rotating body may be an arc-shaped slide groove, and the other may be an arc-shaped protrusion.

[0282] For example, some structural designs of the base 410 in this embodiment may refer to some structural designs of the base 110 in the first embodiment. For example, the base 410 may also include a first branch 414, a second branch 415, a third branch 416, and a fourth branch 417 connected end to end. The second branch 415 may include a first inner side surface 4151 facing the fourth branch 417. The fourth branch 417 may include a second inner side surface 4171 facing the second branch 415. The base 410 may also include a first protrusion 4152 and a second protrusion 4172. The first protrusion 4152 may be fixed to the first inner side surface 4151. The second protrusion 4172 may be fixed to the second inner side surface 4171. The first protrusion 4152 and the second protrusion 4172 may together constitute the first rotating body of the base 410. It should be understood that the above structures may be identical or similar to some of the structures of the base 110 in the first embodiment and will not be described in detail here.

[0283] It should be noted that the torsion structure 430 in this embodiment is Figure 6 The structure of the torsion structure 130 of the rotating mechanism 100 of the first embodiment is substantially the same, and similar parts are not described in detail here. The connection relationship between the base 410 and the torsion structure 430, as well as the connection relationship between the support frame 420 and the torsion structure 430 in this embodiment, is also substantially the same as the connection relationship between the base 110 and the torsion structure 130, as well as the connection relationship between the support frame 120 and the torsion structure 130 of the rotating mechanism 100 of the first embodiment, and similar parts are not described in detail here.

[0284] Figure 29 yes Figure 28 The structure diagram of the support frame 420 shown is from another perspective. Figure 30 yes Figure 26The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the rotating mechanism 400 cut along B1 - B1 .

[0285] like Figures 28 to 30 As shown, the support frame 420 may include a third top surface 420a and a third bottom surface 420b that are arranged opposite to each other along the first direction Z, and a third peripheral side surface 420c connected between the third top surface 420a and the third bottom surface 420b. The first side surface 421 and the second side surface 422 of the support frame 420 may both constitute a part of the third peripheral side surface 420c. The third peripheral side surface 420c may also include a first end surface 425. The first end surface 425 may be connected between the first side surface 421 and the second side surface 422. Specifically, when the rotating mechanism 400 is in the open state, the first end surface 425 may face away from the base 410 and toward the external environment of the rotating mechanism 400. It should be noted that some structural designs of the first side surface 421 and the second side surface 422 of the support frame 420 may refer to the first side surface 121 and the second side surface 122 of the support frame 120 in the first embodiment (please refer to Figure 26 and Figure 27 ), for example, the first side surface 421 and the second side surface 422 of the support frame 420 may also be provided with a first sliding groove 423 and a second sliding groove 424, respectively. The structures of the first sliding groove 423 and the second sliding groove 424 may be the same as the first sliding groove 123 and the second sliding groove 124 in the first embodiment (please refer to Figure 6 The first sliding groove 423 and the second sliding groove 424 can together constitute the second rotating body of the support frame 420.

[0286] For example, the support frame 420 may have a first mounting hole 426 and a second mounting hole 427. The first mounting hole 426 may extend through the third top surface 420a and the third bottom surface 420b of the support frame 420, i.e., the openings of the first mounting hole 426 may be formed on the third top surface 420a and the third bottom surface 420b. The second mounting hole 427 may extend through the first end surface 425 of the support frame 420 and communicate with the first mounting hole 426. The side wall of the first mounting hole 426 facing the second mounting hole 427 is a first side wall 4261. The first side wall 4261 may be opposite and spaced apart from the second mounting hole 427. The first mounting hole 426 also includes a second side wall 4262 facing the first side wall 4261. The distance between the first side wall 4261 and the second side wall 4262 along the longitudinal direction of the support frame 420 is a first dimension K1. In this embodiment, when the rotation mechanism 400 is in the closed state, the longitudinal direction of the support frame 420 is also the second direction X. It should be noted that, in this embodiment, the side of a face facing the space is defined as the front, and the side of a face facing the entity is defined as the back. Unless otherwise specified in the rest of this application, the front and back of a face can refer to the above definitions.

[0287] For example, the support frame 420 may further include a third mounting hole 4281. The third mounting hole 4281 may extend through the third top surface 420a of the support frame 420 and communicate with the second mounting hole 427. The third mounting hole 4281 may be spaced apart from the first mounting hole 426. For example, the third mounting hole 4281 may be substantially cylindrical. The axial direction of the third mounting hole 4281 may intersect with the axial direction of the second mounting hole 427. For example, the axial direction of the third mounting hole 4281 may be perpendicular to the axial direction of the second mounting hole 427. The support frame 420 may further include a fourth mounting hole 4282. The fourth mounting hole 4282 may extend through the third bottom surface 420b of the support frame 420 and communicate with the second mounting hole 427. The fourth mounting hole 4282 may be disposed opposite the third mounting hole 4281. The fourth mounting hole 4282 may be spaced apart from the first mounting hole 426. In some embodiments, the support frame 420 may not include the fourth mounting hole 4282.

[0288] For example, the support frame 420 may further include an escape hole 429. The escape hole 429 may be located on the side of the first mounting hole 426 facing away from the second mounting hole 427. The escape hole 429 may be spaced apart from the first mounting hole 426. The escape hole 429 may extend through the third top surface 420a and the third bottom surface 420b of the support frame 420. The sidewall of the escape hole 429 facing the first mounting hole 426 is a first hole wall 4291. The support frame 420 may further include a limiting groove 4292. The opening of the limiting groove 4292 may be formed in the first hole wall 4291. The limiting groove 4292 may be connected to the escape hole 429.

[0289] In some embodiments, the avoidance hole 429 may also be in communication with the first mounting hole 426 .

[0290] In some embodiments, the first mounting hole 426 and / or the avoidance hole 429 may also only pass through the third top surface 420a of the support frame 420. In this case, the first mounting hole 426 and / or the avoidance hole 429 may also be regarded as a slot structure.

[0291] Figure 31 yes Figure 28 The structure diagram of the locking member 460 of the rotating mechanism 400 shown is from another perspective. Figure 32 yes Figure 28 The illustrated diagram is a schematic diagram of the assembly structure of the locking member 460, the mounting member 470 and the support frame 420 in some embodiments. Figure 33 yes Figure 26 The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the rotating mechanism 400 cut along B1 - B1 .

[0292] like Figures 31 to 33As shown, the locking member 460 may include a cam portion 461 and an extension portion 462. The cam portion 461 may be plate-shaped. The extension portion 462 may be fixedly connected to a portion of the circumferential surface of the cam portion 461. The cam portion 461 of the locking member 460 may be provided with a rotation hole 461a. The locking member 460 may rotate about the central axis of the rotation hole 461a. In other words, the rotation center of the locking member 460 may be the central axis of the rotation hole 461a. For example, the projection of the cam portion 461 in the first direction Z may be circular. In other words, the cam portion 461 may be roughly disc-shaped. The central axis of the rotation hole 461a may be spaced apart from the central axis of the cam portion 461. In other words, the rotation center O1 of the cam portion 461 relative to the support frame 520 is spaced apart from the geometric center O2 of the cam portion 461 itself, and the cam portion 461 has an eccentric cam structure. The locking member 460 may rotate about the rotation center of the cam portion 461. The rotation center O1 of the cam portion 461 is also the rotation center of the locking member 460. Figure 31 The cam portion 461 and extension portion 462 of the locking member 460 are schematically demarcated by dashed lines in the following figures. Although the locking member 460 is described as being divided into two parts (i.e., the cam portion 461 and the extension portion 462) in this embodiment, this does not affect the locking member 460 being an integrally formed structure; that is, the cam portion 461 and the extension portion 462 can be integrally formed. In other embodiments, the locking member 460 may not include the extension portion 462. In other embodiments, the projection of the cam portion 461 in the first direction Z may have other shapes.

[0293] For example, the locking member 460 can be mounted in the second mounting hole 427 of the support frame 420. The rotation hole 461a of the cam portion 461 can be positioned opposite the third mounting hole 4281 and the fourth mounting hole 4282, and can communicate with the third mounting hole 4281 and the fourth mounting hole 4282. The rotation hole 461a can be located between the third mounting hole 4281 and the fourth mounting hole 4282. In this case, a portion of the cam portion 461 can be located within the support frame 420 (for example, a portion of the cam portion 461 can be located within the second mounting hole 427 of the support frame 420, while a portion of the cam portion 461 can be exposed relative to the second mounting hole 427 and located within the first mounting hole 426 of the support frame 420). Another portion of the cam portion 461 can be exposed relative to the second mounting hole 427 and located on the side of the second mounting hole 427 facing away from the first mounting hole 426, that is, located outside the support frame 420. The locking member 460 can be spaced apart from the first mounting hole 426. At least a portion of the extension portion 462 of the locking member 460 may be exposed relative to the second mounting hole 427 and located on a side of the second mounting hole 427 facing away from the first mounting hole 426 , ie, outside the support frame 420 .

[0294] Exemplarily, the rotating mechanism 400 may further include a mounting member 470. The mounting member 470 may be a shaft-like structure. The mounting member 470 may be sequentially inserted into the third mounting hole 4281, the rotating hole 461a, and the fourth mounting hole 4282. At this time, the locking member 460 may be mounted on the support frame 420 through the mounting member 470. The locking member 460 may be rotatably connected to the support frame 420. The rotation center of the locking member 460 may be colinear with the central axis of the mounting member 470. The locking member 460 may rotate relative to the mounting member 470 and the support frame 420 around the rotation center of the locking member 460. The rotation center of the locking member 460 may intersect with the third top surface 420a of the support frame 420. For example, the rotation center of the locking member 460 may be perpendicular to the third top surface 420a of the support frame 420.

[0295] Figure 34 yes Figure 32 The structure shown is a schematic diagram of a cross-sectional structure in an embodiment in which the locking member 460 is cut along B2-B2. Figure 35 yes Figure 32 The structure shown is a schematic diagram of the structure when the locking member 460 is in the unlocked state. Figure 36 yes Figure 35 The structure shown is a schematic diagram of a cross-sectional structure in an embodiment cut along B3-B3.

[0296] like Figures 34 to 36 As shown, locking member 460 can have a locked state and an unlocked state. Locking member 460 can rotate relative to mounting member 470 and support frame 420 to switch between the locked state and the unlocked state. For example, a user can apply a force to extension portion 462 of locking member 460 to enable locking member 460 to rotate relative to mounting member 470 and support frame 420.

[0297] For example, when the locking member 460 is in the locked state (combined with Figure 32 and Figure 34 As shown), in the longitudinal extension direction of the support frame 420, the distance between the locking member 460 and the first side wall 4261 of the first mounting hole 426 is the first distance V1. Figure 35 and Figure 36 As shown in FIG. 4 , in the longitudinal extension direction of the support frame 420 , the distance between the locking member 460 and the first side wall 4261 of the first mounting hole 426 is a second distance V2. The first distance V1 may be smaller than the second distance V2.

[0298] Figure 37 yes Figure 3 The support member 310 shown is a schematic structural diagram of some embodiments from another perspective. Figure 38 yes Figure 37The support member 310 shown is a schematic diagram of a cross-sectional structure in one embodiment cut along B4-B4.

[0299] like Figure 37 and Figure 38 As shown, the support member 310 may include a support body 311, a first mounting portion 312, and a second mounting portion 313. The first mounting portion 312 and the second mounting portion 313 may be located on the same side of the support body 311 and fixedly connected to the support body 311. The first mounting portion 312 may be spaced apart from the second mounting portion 313. The connection end 310a and the support end 310b of the support member 310 may both be formed on the support body 311. For example, the first mounting portion 312 and the second mounting portion 313 may both be located closer to the connection end 310a than the support end. The second mounting portion 313 may be located on the side of the first mounting portion 312 facing away from the support end 310b.

[0300] Exemplarily, the first mounting portion 312 may include a first surface 3121 and a second surface 3122 that are arranged opposite to each other. The first surface 3121 may face the support end 310b of the support member 310. The dimension between the first surface 3121 and the second surface 3122 is the second dimension K2, that is, the dimension of the first mounting portion 312 in the length extension direction of the support member 310 is the second dimension K2. In this embodiment, the length extension direction of the support member 310, that is, the connection end 310a of the support member 310 points in the direction of the support end 310b. When the rotating mechanism 400 is in a closed state, the length extension direction of the support member 310 may also be the second direction X. In other words, the distance between the first surface 3121 and the second surface 3122 in the length extension direction of the support member 310 is the second dimension K2. The second dimension K2 may be smaller than the first dimension K1 (please refer to Figure 28 ). The first mounting portion 312 may further include a mounting groove 3123. The opening of the mounting groove 3123 may be formed on the first surface 3121. In other embodiments, the first mounting portion 312 may not include the mounting groove 3123.

[0301] Exemplarily, the second mounting portion 313 may include a first portion 3131 and a second portion 3132. The first portion 3131 may be fixedly connected to the support body 311. The first portion 3131 may be located on a side of the first mounting portion 312 facing away from the support end 310b and spaced apart from the first mounting portion 312. The second portion 3132 may be fixedly connected to a surface of the first portion 3131 facing away from the support end 310b. The second portion 3132 may be spaced apart from the support body 311 in the thickness direction of the support member 310. In this embodiment, the thickness direction of the support member 310 is also the first direction Z. Exemplarily, the second portion 3132 may be roughly truncated cone-shaped. In other embodiments, the shape of the second portion 3132 may also be other shapes.

[0302] In some embodiments, the support member 310 may not include the second mounting portion 313 .

[0303] Figure 39 yes Figure 37 The illustrated structure is a schematic diagram of the assembly structure of the support member 310 and the rotating mechanism 400 in some embodiments when the rotating mechanism 400 is in a closed state. Figure 40 yes Figure 39 The structure shown is a schematic diagram of the structure when the rotating mechanism 400 is in the open state. Figure 41 yes Figure 40 The structure shown is a schematic diagram of a cross-sectional structure in an embodiment cut along B5-B5. It should be noted that, Figures 39 to 41 The locking members 460 are shown in a locked state.

[0304] like Figures 39 to 41 As shown, the surface of the support body 311 of the support member 310 facing the first mounting portion 312 can overlap the third top surface 420a of the support frame 420. At this time, the first mounting portion 312 of the support member 310 can be located in the first mounting hole 426 of the support frame 420. A portion of the locking member 460 can be located in the mounting groove 3123 of the first mounting portion 312 of the support member 310. The first portion 3131 of the second mounting portion 313 can be located in the avoidance hole 429 of the support frame 420. The second portion 3132 of the second mounting portion 313 can be located in the limiting groove 4292 of the support frame 420. The shape of the limiting groove 4292 can be adapted to the shape of the second portion 3132. That is, the shape of the limiting groove 4292 can be roughly truncated cone-shaped or conical.

[0305] For example, part of the torsion structure 430 may be located within the avoidance hole 429 .

[0306] Figure 42 yes Figure 40 The structure shown is a schematic diagram of a cross-sectional structure in an embodiment cut along B6-B6. Figure 43 yes Figure 41 The structure shown is a schematic diagram of the structure when the locking member 460 is in the unlocked state. Figure 44 yes Figure 41 The structure shown is a schematic diagram of the structure when the locking member 460 is in the unlocked state.

[0307] like Figure 41 and Figure 42 As shown, when the locking member 460 is in the locked state, the locking member 460 can abut against the wall of the mounting groove 3123 of the first mounting portion 312 along the longitudinal extension direction of the support member 310, thereby compressing the first mounting portion 312. At this time, under the action of the locking member 460, the first mounting portion 312 can compress the first side wall 4261 of the first mounting hole 426. Under the action of the locking member 460, the first portion 3131 of the second mounting portion 313 can compress the first hole wall 4291 of the avoidance hole 429. In other words, when the locking member 460 is in the locked state, the support member 310 can be locked with the support frame 420, thereby achieving a fixed connection between the support member 310 and the support frame 420.

[0308] Illustratively, when the locking member 460 is in the locked state, the second portion 3132 of the second mounting portion 313 can also squeeze the side wall of the limiting groove 4292 under the action of the locking member 460 . It can be understood that in this embodiment, by setting the second part 3132 of the second mounting portion 313 of the support member 310 to a truncated cone shape or a conical shape, on the one hand, the radial dimension of the end of the second part 3132 facing away from the first part 3131 can be smaller than the radial dimension of the end of the second part 3132 facing the first part 3131, and the second part 3132 is easy to be installed in the limiting groove 4292, so that the support member 310 is easy to position and assemble during installation; on the other hand, the direction of the force exerted by the groove side wall of the limiting groove 4292 on the second part 3132 can intersect with the length extension direction of the support member 310, so that the limiting groove 4292 can better limit the second part 3132 of the second mounting portion 313, thereby preventing the second part 3132 from shaking in the limiting groove 4292, thereby preventing the support member 310 from shaking and affecting the user experience.

[0309] like Figure 43 and Figure 44As shown, when the locking member 460 is in the unlocked state, the locking member 460 can be spaced apart from the wall of the mounting slot 3123 along the lengthwise extension of the support member 310. That is, a gap exists between the locking member 460 and the first mounting portion 312 along the lengthwise extension of the support member 310. At this point, the entire support member 310 can be moved relative to the support frame 420 in a direction from the connecting end 310a of the support member 310 toward the supporting end 310b, allowing the second portion 3132 of the second mounting portion 313 to slide out of the retaining slot 4292 of the support frame 420. At this point, the user can remove the support member 310 from the rotating mechanism 400.

[0310] It will be appreciated that, unlike conventional rotation mechanisms, which use screws to secure the support member to the support frame, this method requires the user to open the support frame to a larger angle relative to the base before removing the screws with tools to remove the support member from the rotation mechanism. This makes the disassembly process more cumbersome and time-consuming, resulting in a poor user experience. In contrast, the support frame 420 in this embodiment is provided with a first mounting hole 426. The rotation mechanism 400 also includes a locking member 460. The locking member 460 is rotatably connected to the support frame 420, and a portion of the locking member 460 can be positioned within the first mounting hole 426. The locking member 460 can have a locked state and an unlocked state. When the locking member 460 is in the locked state, the distance between the locking member 460 and the wall of the first mounting hole 426 along the length of the support frame 420 is a first distance V1. When the locking member 460 is in the unlocked state, the distance between the locking member 460 and the wall of the first mounting hole 426 along the longitudinal extension direction of the support frame 420 is a second distance V2. The second distance V2 can be smaller than the first distance V1. Thus, when a portion of the support member 310 (in this embodiment, the first mounting portion 312) is located within the first mounting hole 426, the locking member 460 can be rotated to switch it to the locked state, allowing the locking member 460 to squeeze the support member 310. At this time, under the action of the locking member 460, the support member 310 can squeeze the wall of the first mounting hole 426 (in this embodiment, the first sidewall 4261 of the first mounting hole 426), thereby locking with the support frame 420. When the user needs to remove the support member 310 from the rotating mechanism 400, the user only needs to rotate the locking member 460 to switch the locking member 460 from the locked state to the unlocked state, so that the force between the locking member 460 and the support member 310 can be unloaded, and the user can separate the support member 310 from the support frame 420, thereby achieving the removal of the support member 310. At the same time, when the user needs to remove the support member 310, the user only needs to open the rotating mechanism 400 at a small angle to expose the locking member 460, and unlock it by rotating the locking member 460. The disassembly method of the rotating mechanism 400 and the support member 310 of this embodiment is simple to operate, does not require the use of tools, and the disassembly time is short. The rotating mechanism 400 of this embodiment can also achieve rapid disassembly of the rotating mechanism 400 and the support member 310 at a small opening and closing angle, and the user has a good user experience.

[0311] Secondly, the support frame 420 in this embodiment further includes an escape hole 429 spaced apart from the first mounting hole 426. The escape hole 429 may include a first hole wall 4291 facing the first mounting hole 426. The support frame 420 further includes a retaining groove 4292. The opening of the retaining groove 4292 may be formed in the first hole wall 4291. When the support member 310 is secured to the support frame 420, the second mounting portion 313 of the support member 310 may be positioned within the escape hole 429. A portion of the second mounting portion 313 may also be positioned within the retaining groove 4292. Thus, when the locking member 460 is in the locked state and compresses the first mounting portion 312 of the support member 310, the second mounting portion 313 may also be pressed against the first hole wall 4291 under the force of the locking member 460. Furthermore, a portion of the second mounting portion 313 may be embedded in the retaining groove 4292, thereby locking the second mounting portion 313 to the support frame 420. A portion of the second mounting portion 313 can be embedded in the limiting groove 4292 to effectively prevent the support member 310 from shaking relative to the support frame 420. When the locking member 460 is in the unlocked state, the user can apply force to the support member 310, causing the support member 310 to move relative to the support frame 420 in a direction from the connecting end 310a of the support member 310 to the supporting end 310b. This allows a portion of the second mounting portion 313 to slide out of the limiting groove 4292, thereby unlocking the second mounting portion 313 from the support frame 420, thereby disengaging the support member 310 from the support frame 420 and completing the removal of the support member 310. In other words, in this embodiment, the avoidance hole 429 is provided spaced apart from the first mounting hole 426 to accommodate the second mounting portion 313 of the support member 310, and the limiting groove 4292 is provided on the first hole wall 4291 of the avoidance hole 429 to limit the position of a portion of the second mounting portion 313, thereby further securing the support member 310 to the support frame 420. At the same time, when the user needs to remove the support member 310 from the support frame 420, they only need to rotate the locking member 460 to unlock it and slide a portion of the second mounting portion 313 out of the limiting groove 4292 to achieve unlocking between the first mounting portion 312 and the support frame 420, and to achieve unlocking between the second mounting portion 313 and the support frame 420. The disassembly method of the rotating mechanism 400 and the support member 310 of this embodiment is simple to operate, does not require the use of tools, and takes a short time to disassemble. The rotating mechanism 400 of this embodiment can also achieve rapid disassembly of the rotating mechanism 400 and the support member 310 at a relatively small opening and closing angle, providing a better user experience.

[0312] In addition, the shape of the limiting groove 4292 of the support frame 420 in this embodiment can be roughly conical / truncated cone-shaped. That is, the cross-sectional size of the limiting groove 4292 gradually increases in the direction close to the opening of the limiting groove 4292. In this way, when a portion of the second mounting portion 313 of the support member 310 (i.e., the second portion 3132 of the second mounting portion 313 in this embodiment) needs to be installed in the limiting groove 4292, the opening size of the limiting groove 4292 is larger to facilitate the installation of the second mounting portion 313. At the same time, when a portion of the second mounting portion 313 is embedded in the limiting groove 4292, the side walls of the limiting groove 4292 can limit the second mounting portion 313, thereby making it less likely for the support member 310 to shake, thereby improving the user experience.

[0313] Several rotation mechanisms will be introduced below in conjunction with relevant drawings.

[0314] The third embodiment: Figure 45 3 is a schematic structural diagram of a rotating mechanism 500 provided in the present application when it is in a closed state in the third embodiment. Figure 46 yes Figure 45 The structure diagram of the rotating mechanism 500 shown in the third embodiment is in the state. Figure 47 yes Figure 45 The rotating mechanism 500 in some embodiments is shown as a schematic diagram of an exploded structure. For ease of understanding, the rotating mechanism 500 in this embodiment uses different reference numerals from the rotating mechanism 100 in the first embodiment.

[0315] like Figures 45 to 47 As shown, the rotation mechanism 500 can include an open state and a closed state. The rotation mechanism 500 may include a base 510, a support frame 520 and a torsion structure 530. The support frame 520 can be rotatably connected to the base 510. The torsion structure 530 can connect the base 510 and the support frame 520. The torsion structure 530 can be used to provide torsion when the support frame 520 rotates relative to the base 510. The base 510 may include a first rotating body. The support frame 520 may include a second rotating body. The first rotating body of the base 510 can cooperate with the second rotating body of the support frame 520 to enable the support frame 520 to rotate relative to the base 510, thereby enabling the rotation mechanism 500 to switch between the open state and the closed state. One of the first rotating body and the second rotating body may be an arc-shaped slide groove, and the other may be an arc-shaped protrusion.

[0316] It should be noted that the connection relationship between the base 510 and the support frame 520 in this embodiment is roughly the same as the connection relationship between the base 110 and the support frame 120 of the rotating mechanism 100 in the first embodiment, and the same parts are not repeated here.

[0317] Figure 48 yes Figure 47 The torsion structure 530 shown is a schematic diagram of an exploded structure in some embodiments. Figure 49 yes Figure 46 The torsion structure 530 shown is a schematic structural diagram when the rotation mechanism 500 is in an open state. Figure 50 yes Figure 46 The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the rotating mechanism 500 taken along C1-C1.

[0318] like Figures 48 to 50 As shown, the torsion structure 530 may include a first rotating member 531, a second rotating member 532, a first friction plate 534, a second friction plate 535, and a third friction plate 536. The first friction plate 534 may include a first movable end 5341 and a second movable end 5342. The first movable end 5341 of the first friction plate 534 may be provided with a first hole 534a and be mounted on the first rotating member 531. The first friction plate 534 is capable of rotating relative to the first rotating member 531. The second movable end 5342 of the first friction plate 534 may be provided with a second hole 534b and be mounted on the second rotating member 532. The first friction plate 534 is capable of rotating relative to the second rotating member 532. In other embodiments, the torsion structure 530 may not include the second rotating member 532 and / or the third friction plate 536.

[0319] For example, the second friction plate 535 may include a first connecting end 5351 and a second connecting end 5352. The first connecting end 5351 of the second friction plate 535 may be provided with a third hole 535a and be sleeved on the first rotating member 531. The first movable end 5341 of the first friction plate 534 may be rotatable relative to the first connecting end 5351 of the second friction plate 535. That is, the first movable end 5341 of the first friction plate 534 may be rotatably connected to the first connecting end 5351 of the second friction plate 535 via the first rotating member 531. The first movable end 5341 of the first friction plate 534 and the first connecting end 5351 of the second friction plate 535 may be stacked in the third direction Y. The first movable end 5341 of the first friction plate 534 may be closely attached to the first connecting end 5351 of the second friction plate 535, with no gap between them. Thus, when the first friction plate 534 rotates relative to the second friction plate 535, frictional force may be generated between the first and second friction plates 534 and 535. The third hole 535a can be disposed opposite and in communication with the first hole 534a of the first friction plate 534. The shape and size of the third hole 535a can be the same as those of the first hole 534a. The relative rotation center between the first friction plate 534 and the second friction plate 535 is the first rotation center N1. The first rotation center N1 can be collinear with the central axis of the first hole 534a, that is, collinear with the central axis of the first rotating member 531.

[0320] For example, the third friction plate 536 may include a first connecting end 5361 and a second connecting end 5362. The first connecting end 5361 of the third friction plate 536 may be provided with a fourth hole 536a and be sleeved on the second rotating member 532. The second movable end 5342 of the first friction plate 534 may be rotatable relative to the first connecting end 5361 of the third friction plate 536. That is, the second movable end 5342 of the first friction plate 534 may be rotatably connected to the first connecting end 5361 of the third friction plate 536 via the second rotating member 532. The second movable end 5342 of the first friction plate 534 and the first connecting end 5361 of the third friction plate 536 are stacked in the third direction Y. The second movable end 5342 of the first friction plate 534 may be closely attached to the first connecting end 5361 of the third friction plate 536, i.e., there is no gap between them. Therefore, when the first friction plate 534 rotates relative to the third friction plate 536, frictional force may be generated between the first and third friction plates 534 and 536. The fourth hole 536a can be disposed opposite and in communication with the second hole 534b of the first friction plate 534. The shape and size of the fourth hole 536a can be the same as those of the second hole 534b. The relative rotation center between the first friction plate 534 and the third friction plate 536 is the second rotation center N2. The second rotation center N2 can be collinear with the central axis of the second hole 534b, that is, collinear with the central axis of the second rotating member 532.

[0321] For example, the number of each of the first friction plates 534 and the second friction plates 535 can be multiple. The number of first friction plates 534 and the number of second friction plates 535 can be the same or different. The first movable ends 5341 of the multiple first friction plates 534 can be alternately stacked with the first connecting ends 5351 of the multiple second friction plates 535, and both are attached to the first rotating member 531. The first movable ends 5341 of two adjacent first friction plates 534 are closely aligned with the first connecting ends 5351 of the second friction plates 535. This allows for a high friction force to be generated between the multiple first friction plates 534 and the multiple second friction plates 535 when the multiple first friction plates 534 rotate relative to the multiple second friction plates 535.

[0322] Exemplarily, the number of the third friction plates 536 can also be multiple. The number of the third friction plates 536 can be the same as or different from the number of the first friction plates 534. Among them, the second movable ends 5342 of the multiple first friction plates 534 can be alternately stacked with the first connecting ends 5361 of the multiple third friction plates 536, and are all installed on the second rotating member 532. The second movable ends 5342 of two adjacent first friction plates 534 are tightly arranged with the first connecting ends 5361 of the third friction plates 536. In this way, when the multiple first friction plates 534 rotate relative to the multiple third friction plates 536, a larger friction force can be generated between the multiple first friction plates 534 and the multiple third friction plates 536. It should be noted that, Figure 48 For the sake of simplicity in the subsequent drawings, only one of the first friction plates 534 , one of the second friction plates 535 , and one of the third friction plates 536 are labeled.

[0323] For example, the first rotating member 531 and the second rotating member 532 may be rivets. Taking the first rotating member 531 as an example, the first rotating member 531 may include a first end 5311, a shaft 5312, and a second end 5313 connected in sequence. The dimensions of the first end 5311 and the second end 5313 of the first rotating member may both be larger than the dimensions of the first hole 534a of the first friction plate 534 and larger than the dimensions of the third hole 535a of the second friction plate 535. The first and second friction plates 534, 535 may both be sleeved onto the shaft 5312 of the first rotating member 531 and positioned between the first and second ends 5311, 5313 of the first rotating member 531. The first and second ends 5311, 5313 of the first rotating member 531 may both be locked inward. Each of the first and second ends 5311, 5313 may press against an adjacent friction plate (i.e., the first friction plate 534 or the second friction plate 535). At this time, the direction of the force exerted by the first end portion 5311 on the first friction plate 534 and the second friction plate 535 as a whole can be perpendicular to the surface of the first end portion 5311 facing the first friction plate 534. The first movable end 5341 of the first friction plate 534 and the first connecting end 5351 of the second friction plate 535 can be subjected to positive pressure from the first rotating member 531. Thus, when the first friction plate 534 rotates relative to the second friction plate 535, a relatively large friction force can be generated between the first friction plate 534 and the second friction plate 535. Similarly, when the first friction plate 534 rotates relative to the third friction plate 536, a relatively large friction force can also be generated between the first friction plate 534 and the third friction plate 536.

[0324] In some embodiments, the outermost friction plate (i.e., the first friction plate 534 or the second friction plate 535) among the multiple first friction plates 534 and the multiple second friction plates 535 can be pre-tightened first, and then the first end 5311 and the second end 5313 of the first rotating member 531 can be fixedly connected to the outer side surface of the outermost friction plate (i.e., the first friction plate 534 or the second friction plate 535) by welding, so that the two ends of the first rotating member 531 (i.e., the first end 5311 and the second end 5313) can clamp the multiple first friction plates 534 and the multiple second friction plates 535 inward to provide positive pressure to the first friction plates 534 and the second friction plates 535.

[0325] In some other embodiments, the torsion structure 530 may further include an elastic structural member (not shown). The elastic structural member may be disposed on the side of the first end 5311 of the first rotating member 531 facing away from the second end 5313, and compress the first end 5311. Under the action of the elastic structural member, the first end 5311 may compress the adjacent first friction plate 534 or second friction plate 535, thereby providing positive pressure to the first friction plate 534 or second friction plate 535.

[0326] Please refer again Figures 48 to 50 , for ease of understanding, Figure 50 The dotted lines in the figure illustrate the portion of the first friction plate 534 that is blocked by the second friction plate 535 and the portion that is blocked by the third friction plate 536. For example, the contact surface between the first friction plate 534 and the second friction plate 535 can be roughly annular. The inner diameter of the contact surface between the first friction plate 534 and the second friction plate 535 can be r1, and the outer diameter can be R1. That is, the diameter of the first hole 534a of the first friction plate 534 and the diameter of the third hole 535a of the second friction plate 535 can both be r1. The thickness of the first friction plate 534 can be L1. The thickness of the second friction plate 535 can be L2. The total width of the first friction plate 534 and the second friction plate 535 can be W. The positive pressure applied to the outermost friction plate (i.e., the first friction plate 534 or the second friction plate 535) is F1. Thus, the total friction area S1 of the first friction plate 534 and the second friction plate 535 as a whole on the first rotating member 531 can be:

[0327]

[0328] The torque M1 generated by the first friction plate 534 and the second friction plate 535 on the first rotating member 531 can be:

[0329]

[0330] Similarly, the total friction area S2 of the first friction plate 534 and the third friction plate 536 at the second rotating member 532 can be:

[0331]

[0332] The torque M2 generated by the first friction plate 534 and the third friction plate 536 on the first rotating member 531 can be:

[0333]

[0334] The entire torsion structure 530 can provide a torsion force M 总 It can be:

[0335] M 总 =a*M1+b*M2

[0336] The coefficient a and the coefficient b depend on the relative positions of the first rotation center N1 and the second rotation center N2.

[0337] Figure 51 yes Figure 47 FIG. 5 is a schematic diagram of the assembly structure of the support frame 520 and the torsion structure 530 . Figure 52 yes Figure 45 The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the rotating mechanism 500 taken along C2-C2. Figure 53 yes Figure 46 The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the rotating mechanism 500 taken along C1-C1.

[0338] like Figures 51 to 53 As shown, the second connecting end 5352 of the second friction plate 535 can be fixedly connected to the support frame 520. When the support frame 520 rotates relative to the base 510 about the first axis T1, the support frame 520 can drive the first connecting end 5351 of the second friction plate 535 to rotate relative to the first movable end 5341 of the first friction plate 534 about the first rotation center N1. The first axis T1 can be spaced apart from the first rotation center N1. The second friction plate 535 and the support frame 520 do not rotate or move relative to each other. At this time, the first friction plate 534 and the second friction plate 535 can generate a large torque at the first rotation center N1.

[0339] For example, the support frame 520 may include a support frame body 521, a first baffle 522, and a second baffle 523 ( Figure 47The structure of the support body 521, the first baffle 522, and the second baffle 523 is also shown. The support body 521 may have an installation space 521a. The installation space 521a can be used to accommodate at least a portion of the second friction plate 535. The first baffle 522 and the second baffle 523 can be located in the installation space 521a and fixedly connected to the support body 521 at both ends. The first baffle 522 and the second baffle 523 can be spaced apart in the first direction Z.

[0340] For example, the rotation mechanism 500 may further include a first fixing shaft 561. The first fixing shaft 561 may be installed through the support body 521 and the second connecting end 5352 of the second friction plate 535 to secure the second connecting end 5352 of the second friction plate 535 to the support body 520. In this case, a portion of the second friction plate 535 may be located between the first baffle 522 and the second baffle 523. Under the influence of the first baffle 522 and the second baffle 523, the second friction plate 535 is prevented from rotating relative to the support body 520. Thus, by arranging the first baffle 522 and the second baffle 523 within the mounting space 521a of the support body 521, the structural stability of the support body 521 can be enhanced. On the other hand, the first baffle 522 and the second baffle 523 can also be used to support the second friction plate 535. When the support frame 520 is overloaded, the support frame body 521 and the second friction plate 535 can still maintain structural stability, thereby effectively preventing deformation of the support frame 520 and / or the second friction plate 535 due to the support frame 520 overload. Furthermore, the first baffle 522 and the second baffle 523 can also prevent the second friction plate 535 from rotating relative to the support frame 520. At least one of the first baffle 522 and the second baffle 523 can be detachably connected to the support frame body 521 to facilitate assembly of the second friction plate 535.

[0341] In other embodiments, the second connection end 5352 of the second friction plate 535 may also be fixedly connected to the support frame 520 by welding, bonding, screwing, or other methods.

[0342] Figure 54 yes Figure 45 The illustrated diagram is a cross-sectional structural diagram of an embodiment of the rotating mechanism 500 taken along C3-C3. Figure 55 yes Figure 45 The illustrated diagram is a cross-sectional structural diagram of an embodiment of the rotating mechanism 500 taken along C2-C2. Figure 56 yes Figure 46 The cross-sectional structure diagram of the rotating mechanism 500 shown is a schematic diagram of an embodiment cut along C1-C1.

[0343] like Figures 54 to 56As shown, the second connection end 5362 of the third friction plate 536 can be slidably connected to the base 510. When the support frame 520 rotates relative to the base 510, the second friction plate 535 can rotate relative to the first friction plate 534. The first friction plate 534 can rotate relative to the third friction plate 536. Under the action of the support frame 520, the second friction plate 535 can also drive the first friction plate 534 to move relative to the base 510, and the first friction plate 534 can also drive the third friction plate 536 to slide relative to the base 510. The third friction plate 536 and the base 510 do not rotate relative to each other. At this time, the first friction plate 534 and the third friction plate 536 can generate a large torque at the second rotation center N2.

[0344] For example, the rotating mechanism 500 may further include a first slider 562, a second slider 563, and a second fixed shaft 564 ( Figure 47 The structure of the first slider 562, the second slider 563, and the second fixed shaft 564 is also shown. The first slider 562 and the second slider 563 can have the same shape and size. There can be two second fixed shafts 564. The two second fixed shafts 564 can have the same shape and size. In this embodiment, the two second fixed shafts 564 are numbered the same.

[0345] Exemplarily, both the first slider 562 and the second slider 563 can be slidably connected to the base 510. In this embodiment, the first inner side surface 5151 of the base 510 can also be provided with a first sliding protrusion 5153. The first slider 562 can be provided with a first sliding groove 5621 that cooperates with the first sliding protrusion 5153, and the first slider 562 can be slidably connected to the base 510 by cooperating with the first sliding protrusion 5153. Similarly, the second slider 563 can also be provided with a second sliding groove 5631 that cooperates with the second sliding protrusion 5173 of the second inner side surface 5171 of the base 510, so that the second slider 563 is slidably connected to the base 510. In other embodiments, the first slider 562 and the second slider 563 can also be slidably connected to the base 510 in other ways. In some other embodiments, the first slider 562 and the second slider 563 can also be an integrally molded structure. It should be noted that the structural setting of the first inner side surface 5151 of the base 510 in this embodiment is the same as Figure 7 The structure of the first inner side surface 1151 of the base 110 in the first embodiment is the same as that in the first embodiment, and will not be repeated here. Figure 7 The structural arrangement of the second inner side surface 1171 of the base 110 in the first embodiment is the same and will not be described again here.

[0346] For example, the second connection end 5362 of the third friction plate 536 can be located between the first slider 562 and the second slider 563. Two second fixing shafts 564 can be sequentially mounted on the first slider 562, the second friction plate 535, and the second slider 563 to secure the second connection end 5362 of the third friction plate 536 to the first and second sliders 562, 563. In other words, the second connection end 5362 of the third friction plate 536 can be slidably connected to the base 510 via the first and second sliders 562, 563. In other embodiments, the second connection end 5362 of the third friction plate 536 can be fixedly connected to the first and second sliders 562, 563 via other means. In other embodiments, the rotating mechanism 500 may not include the first and second sliders 562, 563. The second connection end 5362 of the third friction plate 536 can also be slidably connected to the base via other means.

[0347] Please refer again Figure 55 and Figure 56 When the support frame 520 rotates relative to the base 510, the support frame 520 can drive the second friction plate 535 to rotate relative to the base 510 about the first axis T1. At this time, the first connection end 5351 of the second friction plate 535 can rotate relative to the first movable end 5341 of the first friction plate 534 about the first rotation center N1. The second friction plate 535 can also drive the first friction plate 534 to move relative to the base 510. Under the action of the second friction plate 535, the first friction plate 534 can drive the third friction plate 536 to slide relative to the base 510. At this time, the second movable end 5342 of the first friction plate 534 can rotate relative to the first connection end 5361 of the third friction plate 536 about the second rotation center N2. When the support frame 520 rotates relative to the base 510, the first friction plate 534 can swing relative to the base 510. In other embodiments, the third friction plate 536 can also be movably connected to the base 510 through the cooperation of an arc-shaped groove and an arc-shaped protrusion. When the support frame 520 rotates relative to the base 510, the second friction plate 535 and the third friction plate 536 can rotate relative to the base 510. The first friction plate 534 can move relative to the base 510, and the first friction plate 534 and the base 510 always remain parallel.

[0348] It is understandable that the support frame of a general rotating mechanism is usually connected to the base through a physical rotating shaft, or the support frame is connected to the base through a circular shape and the shaft core. The physical rotating shaft and the shaft core need to withstand axial torque. In order to support the placement of electronic equipment at different angles, the rotating mechanism needs to provide a larger torque for the support. In order to increase the torque, the general rotating mechanism usually also needs to increase the diameter of the physical rotating shaft or the diameter of the shaft core so that it can withstand a larger axial torque to meet the large torque requirements. However, as the diameter of the physical rotating shaft or the shaft core increases, the overall thickness of the rotating mechanism also increases, which is not conducive to the thinning setting of the electronic equipment.

[0349] The torsion structure 530 in this embodiment includes a first rotating member 531, a first friction plate 534, and a second friction plate 535. The first movable end 5341 of the first friction plate 534 is rotatably connected to the first connecting end 5351 of the second friction plate 535 via the first rotating member 531. The second connecting end 5352 of the second friction plate 535 is fixedly connected to the support frame 520. The first movable end 5341 of the first friction plate 534 and the first connecting end 5351 of the second friction plate 535 are stacked in the third direction Y and contact each other with no gap between them. When the support frame 520 rotates relative to the base 510, the support frame 520 can drive the second friction plate 535 to rotate relative to the base 510. At this time, the first connecting end 5351 of the second friction plate 535 can rotate relative to the first movable end 5341 of the first friction plate 534. The second movable end 5342 of the first friction plate 534 can slide relative to the base 510. The first friction plate 534 can also move relative to the base 510 under the action of the second friction plate 535. Friction is generated between the first and second friction plates 534, 535, providing torque to the rotation mechanism 500. In this situation, the first rotating member is only subjected to tensile and compressive forces along its axial direction, resulting in relatively low forces. Thus, the diameter of the first rotating member 531 is not limited by the torque provided by the rotation mechanism 500. In other words, in this embodiment, the diameter of the first rotating member 531 can be made smaller, allowing the rotation mechanism 500 to achieve high torque while maintaining a relatively thin overall thickness, thus facilitating a thinner design for the rotation mechanism 500.

[0350] Secondly, the torque generated by the torsion structure 530 in this embodiment is independent of the angle at which the support frame 520 rotates relative to the base 510. The torsion structure 530 can provide torque at any position of the support frame 520 relative to the base 510. In other words, the rotation mechanism 500 in this embodiment can also achieve hovering of the support frame 520 and the base 510 at any angle, meeting the user's diverse usage needs. Furthermore, the force required to open the support frame 520 relative to the base 510 to different angles is relatively consistent. This means that the force required to open and close the rotation mechanism 500 does not vary with the angle of opening and closing, thereby improving the user experience.

[0351] Furthermore, the rotation mechanism in this embodiment may include multiple first friction plates 534 and multiple second friction plates 535, which are alternately arranged along the axial direction of the first rotating member 531 (i.e., the width direction of the rotation mechanism 500). This increases the total friction area between the multiple first friction plates 534 and the multiple second friction plates 535, effectively increasing the friction force during relative rotation between the multiple first friction plates 534 and the multiple second friction plates 535, thereby increasing torque. Furthermore, the multiple first friction plates 534 and the multiple second friction plates 535 are arranged along the width direction of the rotation mechanism 500 (i.e., the third direction Y in this embodiment), without affecting the thickness of the rotation mechanism 500. In other words, the rotation mechanism 500 in this embodiment can achieve a thin design while maintaining high torque, thereby facilitating a thin design for the entire electronic device 1.

[0352] In addition, the torsion structure 530 in this embodiment may further include a second rotating member 532 and a third friction plate 536. The second movable end 5342 of the first friction plate 534 is rotatably connected to the first connecting end 5361 of the third friction plate 536 via the second rotating member 532. The second connecting end 5362 of the third friction plate 536 is slidably connected to the base 510. The second movable end 5342 of the first friction plate 534 and the second connecting end 5362 of the third friction plate 536 are stacked in the third direction Y and contact each other with no gap between them. When the support frame 520 rotates relative to the base 510, the support frame 520 can drive the first connecting end 5351 of the second friction plate 535 to slide relative to the base 510 and rotate relative to the first movable end 5341 of the first friction plate 534. Frictional force can be generated between the first friction plate 534 and the second friction plate 535. The second movable end 5342 of the first friction plate 534 slides relative to the base 510 under the action of the second friction plate 535, driving the third friction plate 536 to slide relative to the base 510. At this point, the second movable end 5342 of the first friction plate 534 and the first connecting end 5361 of the third friction plate 536 rotate relative to each other. Friction is generated between the first and third friction plates 534, 536. The second rotating member 532 is subjected only to tensile and compressive forces along its axial direction. Thus, by enabling the first friction plate 534 to rotate relative to the second and third friction plates 535, 536, respectively, friction is generated, providing torque to the entire rotating mechanism 500. Specifically, the rotating mechanism 500 can generate torque at the relative rotation center between the first and second friction plates 534, 535 (in this embodiment, the first rotation center N1) and at the relative rotation center between the first and third friction plates 534, 536 (in this embodiment, the second rotation center N2). Compared to conventional rotation mechanisms that generate torque at only one rotation center, the rotation mechanism 500 in this embodiment, by disposing a third friction plate 536 between the second movable end 5342 of the first friction plate 534 and the base 510, allows the first and third friction plates 534, 536 to rotate relative to each other while also generating torque. In other words, while the rotation mechanism 500 has the same dimensions, the rotation mechanism 500 in this embodiment can generate torque at two rotation centers (in this embodiment, the first rotation center N1 and the second rotation center N2), thereby achieving both a compact design and high torque.

[0353] Fourth embodiment: Figure 57 3 is a schematic structural diagram of a rotating mechanism 600 provided in the present application when it is in a closed state in the fourth embodiment. Figure 58 yes Figure 57 The structure diagram of the rotating mechanism 600 shown in the fourth embodiment is in the open state. Figure 59 yes Figure 57 The rotating mechanism 600 in some embodiments is shown as a schematic diagram of an exploded structure. For ease of understanding, the rotating mechanism 600 in this embodiment uses different reference numerals from the rotating mechanism 100 in the first embodiment.

[0354] like Figures 57 to 59 As shown, the rotation mechanism 600 can have an open state and a closed state. The rotation mechanism 600 may include a base 610, a support frame 620, and a torsion structure 630. The support frame 620 can be rotatably connected to the base 610. The torsion structure 630 can connect the base 610 and the support frame 620. The torsion structure 630 can be used to provide torque when the support frame 620 rotates relative to the base 610. The base 610 may include a first rotating body. The support frame 620 may include a second rotating body. The first rotating body of the base 610 can cooperate with the second rotating body of the support frame 620 to enable the support frame 620 to rotate relative to the base 610, thereby enabling the rotation mechanism 600 to switch between the open state and the closed state. One of the first rotating body and the second rotating body may be an arc-shaped sliding groove, and the other may be an arc-shaped protrusion. The support frame 620 can rotate relative to the base 610 about a first axis T1. The first axis T1 may be a virtual axis and is spaced apart from the rotation mechanism 600.

[0355] Figure 60 yes Figure 59 The illustrated schematic diagram of the exploded structure of the support frame 620 in some embodiments. Figure 61 yes Figure 60 The structure shown is a schematic diagram of the structure from another perspective. Figure 62 yes Figure 59 The structure diagram of the support frame 620 shown is from another perspective.

[0356] like Figures 60 to 62 As shown, the support frame 620 may include a support frame body 621 and a transmission member 622. The support frame body 621 may include a first side portion 6211, a middle portion 6212 and a second side portion 6213. The first side portion 6211 and the second side portion 6213 may be located on opposite sides of the middle portion 6212 and fixedly connected to the middle portion 6212. The first side portion 6211 and the second side portion 6213 may be spaced apart in the third direction Y. It should be noted that, although the support frame body 621 is described as a plurality of parts in this embodiment (i.e., the first side portion 6211, the middle portion 6212 and the second side portion 6213), it does not affect the support frame body 621 being an integrally formed structure, i.e., the first side portion 6211, the middle portion 6212 and the second side portion 6213 may be integrally formed.

[0357] For example, the first side portion 6211 may include a first surface 6211a facing the second side portion 6213. The first side portion 6211 may be provided with a first sliding groove 6211b. The opening of the first sliding groove 6211b may be formed on the first surface 6211a. That is, the opening of the first sliding groove 6211b may face the second side portion 6213. The second side portion 6213 may include a second surface 6213a facing the first side portion 6211. The second side portion 6213 may be provided with a second sliding groove 6213b. The opening of the second sliding groove 6213b may be formed on the second surface 6213a. That is, the opening of the second sliding groove 6213b may face the first side portion 6211. The first sliding groove 6211b and the second sliding groove 6213b may have the same shape and size. Both the first sliding groove 6211b and the second sliding groove 6213b may be arc-shaped grooves. The first sliding groove 6211 b and the second sliding groove 6213 b may together constitute a second rotating body of the support frame 620 .

[0358] For example, the transmission member 622 can be fixedly connected to the middle portion 6212 by screwing, bonding, etc. In this embodiment, the transmission member 622 can be fixedly connected to the middle portion 6212 by screwing. The transmission member 622 can be located between the first side portion 6211 and the second side portion 6213, and can be spaced apart from the first side portion 6211 and the second side portion 6213.

[0359] For example, the transmission member 622 may include a first section 6221 and a second section 6222 connected to each other. The first section 6221 may be spaced apart from the opening of the first sliding slot 6211b of the first side portion 6211. The second section 6222 may be located on the side of the first section 6221 facing away from the first side portion 6211 and spaced apart from the opening of the second sliding slot 6213b of the second side portion 6213. The second section 6222 may be provided with a first gear 6223. The first gear 6223 may be spaced apart from the second side portion 6213.

[0360] In other embodiments, the transmission member 622 may also be integrally formed with the support frame body 621 , that is, the support frame 620 may also be an integrally formed structure.

[0361] Figure 63 yes Figure 59 The torsion structure 630 shown is a schematic diagram of an exploded structure in some embodiments. Figure 64 yes Figure 57 The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the rotating mechanism 600 cut along D1 - D1 .

[0362] like Figure 59 、 Figure 63 as well as Figure 64As shown, the torsion structure 630 may include a first rotating member 630a, a second rotating member 630b and a torsion member 630c. The first rotating member 630a may include a first rotating shaft 631 and a second gear 632. The first rotating shaft 631 may include a first end face 6311 and a second end face 6312 arranged opposite to each other. The second gear 632 may be sleeved on the first rotating shaft 631. The second gear 632 may be fixed to the first rotating shaft 631. Exemplarily, the second gear 632 may be fixedly connected to the first rotating shaft 631 by means of snap-fit ​​(e.g., keyway fitting), welding, bonding, etc. Alternatively, the second gear 632 may also be integrally formed with the first rotating shaft 631, that is, the first rotating member 630a may be an integrally formed gear shaft structure. In this case, no relative rotation occurs between the second gear 632 and the first rotating shaft 631.

[0363] For example, the second gear 632 may be located between the first end surface 6311 and the second end surface 6312 of the first rotating shaft 631. The second gear 632 may be located closer to the second end surface 6312 than to the first end surface 6311 of the first rotating shaft 631. In other words, the distance between the second gear 632 and the first end surface 6311 of the first rotating shaft 631 may be greater than the distance between the second gear 632 and the second end surface 6312 of the first rotating shaft 631.

[0364] Exemplarily, the second rotating member 630b may include a second rotating shaft 633 and a third gear 634. The second rotating shaft 633 may include a first end face 6331 and a second end face 6332 arranged opposite to each other. The third gear 634 may be sleeved on the second rotating shaft 633. The third gear 634 may be fixed to the second rotating shaft 633. Exemplarily, the third gear 634 may be fixedly connected to the second rotating shaft 633 by means of snap-fit ​​(e.g., keyway fitting), welding, bonding, etc. Alternatively, the third gear 634 may be integrally formed with the second rotating shaft 633, that is, the second rotating member 630b may be an integrally formed gear shaft structure. In this case, relative rotation does not occur between the third gear 634 and the second rotating shaft 633.

[0365] For example, the third gear 634 can be located between the first end surface 6331 and the second end surface 6332 of the second rotating shaft 633. The third gear 634 can be positioned closer to the second end surface 6332 than the first end surface 6331 of the second rotating shaft 633. That is, the distance between the third gear 634 and the first end surface 6331 of the second rotating shaft 633 can be greater than the distance between the third gear 634 and the second end surface 6332 of the second rotating shaft 633. In other embodiments, the first rotating shaft 631 and the second rotating shaft 633 may have different shapes and sizes, and / or the second gear 632 and the third gear 634 may have different shapes and sizes.

[0366] For example, the first rotating shaft 631 and the second rotating shaft 633 can have the same shape and size. The third gear 634 and the second gear 632 can have the same shape and size. In other words, the first rotating member 630a and the second rotating member 630b can have the same shape and size. This allows the first rotating member 630a and the second rotating member 630b to be manufactured using the same mold, simplifying the manufacturing process and improving manufacturing efficiency.

[0367] Please refer again Figure 59 、 Figure 63 as well as Figure 64 The torsion member 630c may include a first end 635 and a second end 636. The first end 635 of the torsion member 630c may be provided with a first through-hole 6351 and may be mounted on the first rotating shaft 631 of the first rotating member 630a. The first end 635 of the torsion member 630c may be located on the side of the second gear 632 facing the first end face 6311 of the first rotating shaft 631. The second end 636 of the torsion member 630c may be provided with a second through-hole 6361 and may be mounted on the rotating shaft of the second rotating member 630b. The second end 636 of the torsion member 630c may be located on the side of the third gear 634 facing the first end face 6331 of the second rotating shaft 633. In this case, the second gear 632 may mesh with the third gear 634. The first rotating shaft 631 may be spaced apart from the second rotating shaft 633. The first end 635 of the torsion member 630c may have an interference fit with the first rotating shaft 631. The second end 636 of the torsion member 630 c may be interference-fitted with the second rotating shaft 633 .

[0368] In some embodiments, the torsion member 630c may include multiple torsion plates. The multiple torsion plates may have identical shapes and sizes. One end of each torsion plate may be sleeved onto the first rotating shaft 631 and form an interference fit with the first rotating shaft 631. The other end of each torsion plate may be sleeved onto the second rotating shaft 633 and form an interference fit with the second rotating shaft 633. The torsion plates may be made of an elastic material.

[0369] Figure 65 yes Figure 59 The shown schematic diagram is a structural diagram of the base 610 from another perspective.

[0370] like Figure 59 and Figure 65 As shown, some structural designs of the base 610 in this embodiment can refer to some structural designs of the base 110 in the first embodiment (please refer to Figure 26 and Figure 27), for example, the base 610 may also include a first branch 614, a second branch 615, a third branch 616, and a fourth branch 617 connected end to end. The first branch 614, the second branch 615, the third branch 616, and the fourth branch 617 may enclose an inner space 610a of the base 610. The second branch 615 may include a first inner side surface 6151 disposed toward the fourth branch 617. The fourth branch 617 may include a second inner side surface 6171 disposed toward the second branch 615. The above structures may be substantially the same as or similar to the partial structures of the base 110 in the first embodiment, and will not be described in detail here.

[0371] For example, the second branch 615 may further include a first outer side surface 6152 disposed away from the fourth branch 617. The base 610 may further include a first protrusion 6153. The first protrusion 6153 may be fixed to the first outer side surface 6152 of the second branch 615. The first protrusion 6153 may be in the shape of an arc. The first protrusion 6153 may be disposed closer to the third branch 616 than the first branch 614.

[0372] For example, the fourth branch 617 may further include a second outer side surface 6172 disposed away from the second branch 615. The base 610 may further include a second protrusion 6173. The second protrusion 6173 may be fixed to the second outer side surface 6172 of the fourth branch 617. The second protrusion 6173 may be arc-shaped. The second protrusion 6173 may be disposed closer to the third branch 616 than the first branch 614. The second protrusion 6173 and the first protrusion 6153 may have the same shape and size. The second protrusion 6173 and the first protrusion 6153 may together constitute a first rotating body of the base 610.

[0373] For example, the base 610 may further include two first mounting holes 618. One of the first mounting holes 618 may be located in the second branch 615, and the other first mounting hole 618 may be located in the fourth branch 617. The two first mounting holes 618 may be arranged opposite each other. Both first mounting holes 618 may be located closer to the first branch 614 than to the third branch 616. The base 610 may further include two second mounting holes 619. One of the second mounting holes 619 may be located in the second branch 615, and the other second mounting hole 619 may be located in the fourth branch 617. The two second mounting holes 619 may be arranged opposite each other. Both second mounting holes 619 may be located closer to the first branch 614 than to the third branch 616.

[0374] Figure 66 yes Figure 59 FIG. 6 is a schematic diagram of the assembly structure of the torsion structure 630 and the base 610 in some embodiments. Figure 67 yes Figure 57The illustrated diagram is a partial cross-sectional structural diagram of an embodiment of the rotating mechanism 600 cut along D1 - D1 .

[0375] like Figure 66 and Figure 67 As shown, the two ends of the first rotating member 630a can be respectively mounted on the second branch 615 and the fourth branch 617 of the base 610. The two ends of the second rotating member 630b can also be respectively mounted on the second branch 615 and the fourth branch 617 of the base 610. Specifically, the two ends of the first rotating shaft 631 of the first rotating member 630a can be respectively inserted into the two first mounting holes 618 of the base 610. The first rotating member 630a can rotate relative to the base 610. The two ends of the second rotating shaft 633 of the second rotating member 630b can respectively insert into the two second mounting holes 619 of the base 610. The second rotating member 630b can rotate relative to the base 610. In this case, the first rotating member 630a and the second rotating member 630b can be arranged along the second direction X. The second gear 632, the third gear 634, and the torsion member 630c can all be located between the second branch 615 and the fourth branch 617.

[0376] For example, the second gear 632 and the third gear 634 may be disposed opposite to the fourth branch 617. The torsion member 630c may be disposed opposite to the second branch 615. That is, the second gear 632 and the third gear 634 may be located between the torsion member 630c and the fourth branch 617.

Figure 70 yes Figure 58 The illustrated diagram is a cross-sectional structural diagram of a rotating mechanism 600 in one embodiment, taken along D4-D4.

[0378] like Figures 68 to 70As shown, the first protrusion 6153 of the base 610 can be mounted in the first sliding groove 6211b of the support frame 620. The second protrusion 6173 of the base 610 can be mounted in the second sliding groove 6213b of the support frame 620. In this case, the base 610 can be located between the first side portion 6211 and the second side portion 6213 of the support body 621 of the support frame 620. The transmission member 622 of the support frame 620 can be located between the second branch 615 and the fourth branch 617 of the base 610. In other words, the second branch 615 of the base 610 can be located between the first side portion 6211 of the support body 621 and the transmission member 622. The fourth branch 617 of the base 610 can be located between the second side portion 6213 of the support body 621 and the transmission member 622. The first axis T1 can coincide with the line connecting the center of the first sliding groove 6211b and the center of the second sliding groove 6213b. The support frame 620 can rotate relative to the base 610 around the first axis T1.

Figure 72 yes Figure 57 The cross-sectional structure diagram of the rotating mechanism 600 shown is a schematic diagram of an embodiment cut along D6-D6.

Figure 74 yes Figure 58 The illustrated diagram is a cross-sectional structural diagram of a rotating mechanism 600 in one embodiment, taken along D8-D8.

[0380] like Figure 71 and Figure 72 As shown, the transmission member 622 of the support frame 620 can be located on the side of the first rotating member 630a facing away from the second rotating member 630b. The first section 6221 of the transmission member 622 can be positioned opposite the torsion member 630c. The second section 6222 of the transmission member 622 can be positioned opposite the second gear 632 of the first rotating member 630a. The first gear 6223 of the transmission member 622 can mesh with the second gear 632 of the first rotating member 630a.

[0381] like Figure 73 and Figure 74As shown, when the support frame 620 rotates relative to the base 610, the first gear 6223 of the support frame 620 can drive the second gear 632 of the first rotating member 630a to rotate. Under the action of the second gear 632, the first rotating shaft 631 of the first rotating member 630a can rotate relative to the first end 635 of the torsion member 630c about the first rotation center N1. The first rotation center N1 can be the central axis of the first rotating member 630a. At this time, the first rotating member 630a and the torsion member 630c can generate torque at the first rotation center N1.

[0382] For example, when the support frame 620 is aligned with the base 610, the second gear 632 of the first rotating member 630a can also drive the third gear 634 of the second rotating member 630b to rotate. Under the action of the third gear 634, the second rotating shaft 633 of the second rotating member 630b can rotate relative to the second end 636 of the torsion member 630c about the second rotation center N2. The second rotation center N2 can be the central axis of the second rotating member 630b. In this case, the second rotating member 630b and the torsion member 630c can generate torque at the second rotation center N2.

[0383] At this time, the total torque M of the rotating mechanism 600 总 It can be:

[0384] M 总 =k1*M1+k2*M2

[0385] Here, M1 is the torque generated by the first rotating member 630a and the torsion member 630c at the first rotation center N1, M2 is the torque generated by the second rotating member 630b and the torsion member 630c at the second rotation center N2, k1 is the influence coefficient of the second gear 632, and k2 is the influence coefficient of the third gear 634. It should be noted that the influence coefficient of the gear is a coefficient related to the pitch circle radius of the gear.

[0386] In some embodiments, the second rotating member 630b may not include the third gear 634. In this case, when the support frame 620 rotates relative to the base 610, the first gear 6223 of the support frame 620 can drive the second gear 632 of the first rotating member 630a to rotate. Under the action of the second gear 632, the first rotating shaft 631 of the first rotating member 630a can rotate relative to the first end 635 of the torsion member 630c about the first rotation center N1. The second rotating member 630b and the second end 636 of the torsion member 630c do not rotate relative to each other. In this way, the second rotating member 630b can be used to fix the torsion member 630c, thereby preventing the torsion member 630c from rotating when the first rotating shaft 631 rotates. In this case, the total torque of the rotating mechanism 600 is the torque generated by the first rotating member 630a and the torsion member 630c at the first rotation center N1.

[0387] It's understandable that the support frame of a typical rotating mechanism is typically connected to the base via a physical shaft, or the support frame is connected to the base via a circle that cooperates with the shaft core. Therefore, when the rotating mechanism is in the open position, the physical shaft is exposed relative to the electronic device, and the circle is also exposed relative to the electronic device due to its rotation relative to the base. This reduces the overall aesthetics of the electronic device and the user experience.

[0388] The support frame 620 of the rotating mechanism 600 in this embodiment can be provided with a first gear 6223. The torsion structure 630 can include a first rotating member 630a, a second rotating member 630b, and a torsion member 630c. The first rotating member 630a and the second rotating member 630b can both be mounted on the base 610. The first rotating member 630a can include a first rotating shaft 631 and a second gear 632 that is sleeved and fixed on the first rotating shaft 631. In other words, the first rotating member 630a is a gear shaft structure. The first end 635 of the torsion member 630c can be sleeved on the first rotating shaft 631 and have an interference fit with the first rotating shaft 631. The second end 636 of the torsion member 630c can be sleeved on the second rotating member 630b. The first gear 6223 of the support frame 620 can mesh with the second gear 632 of the first rotating member 630a. When the support frame 620 rotates relative to the base 610, the first gear 6223 of the support frame 620 can drive the second gear 632 of the first rotating member 630a to rotate. The first rotating shaft 631 of the first rotating member 630a can rotate relative to the first end 635 of the torsion member 630c under the action of the second gear 632, thereby generating a torsion force. The torsion structure 630 as a whole will not move or rotate relative to the base 610. In this way, by setting up a gear transmission, when the rotating mechanism 600 is in the open state, the torsion structure 630 as a whole will not rotate relative to the base 610, so that the torsion structure 630 can be better hidden in the rotating mechanism 600 and will not be exposed relative to the electronic device, which is beneficial to improving the overall aesthetics of the electronic device and enhancing the user experience.

[0389] Secondly, the torque generated by the torsion structure 630 in this embodiment is independent of the angle at which the support frame 620 rotates relative to the base 610. The torsion structure 630 can provide torque regardless of the position to which the support frame 620 rotates relative to the base 610. In other words, the rotation mechanism 600 in this embodiment can also enable the support frame 620 and the base 610 to hover at any angle, meeting the user's diverse usage needs. Furthermore, the force required to open the support frame 620 relative to the base 610 to different angles is relatively consistent. This means that the force required to open and close the rotation mechanism 600 does not vary with the angle, thus improving the user experience.

[0390] Secondly, the support frame of a general rotating mechanism is usually connected to the base through a physical rotating shaft, or the support frame is connected to the base through a circular shape and the shaft core. The physical rotating shaft and the shaft core need to withstand axial torque. In order to support the placement of electronic equipment at different angles, the rotating mechanism 600 needs to provide a larger torque for the support. In order to increase the torque, a general rotating mechanism usually needs to increase the diameter of the physical rotating shaft or the diameter of the shaft core so that it can withstand a larger axial torque to meet the large torque requirements. However, as the diameter of the physical rotating shaft or the shaft core increases, the overall thickness of the rotating mechanism 600 also increases, which is not conducive to the thinning setting of the electronic equipment.

[0391] In this embodiment, the second rotating member 630b may include a second rotating shaft 633 and a third gear 634 mounted and fixed on the second rotating shaft 633. That is, the second rotating member 630b is also a gear shaft structure. The third gear 634 can mesh with the second gear 632. The first rotating member 630a and the second rotating member 630b can be arranged in the longitudinal extension direction of the rotating mechanism 600 (also known as the second direction X in this embodiment). In this way, when the support frame 620 rotates relative to the base 610, the first gear 6223 of the support frame 620 can drive the second gear 632 of the first rotating member 630a to rotate, so that the first rotating shaft 631 of the first rotating member 630a and the first end 635 of the torsion member 630c rotate relative to each other, thereby generating torque. The second gear 632 of the first rotating member 630a can also drive the third gear 634 to rotate, causing the second rotating shaft 633 of the second rotating member 630b and the second end 636 of the torsion member 630c to rotate relative to each other, thereby generating torque, thereby increasing the total torque of the entire rotating mechanism 600. In other words, the rotating mechanism 600 in this embodiment, by providing multiple intermeshing gear shafts (i.e., the first rotating member 630a and the second rotating member 630b in this embodiment) along the length of the rotating mechanism 600, can increase the total torque of the entire rotating mechanism 600 without increasing the overall thickness of the rotating mechanism 600. The rotating mechanism 600 in this embodiment can achieve a thin design of the rotating mechanism 600 while maintaining high torque, thereby facilitating a thin design of the entire electronic device.

[0392] In addition, compared to the case where the support frame is located on the inner side of the base, the support frame needs to be provided with an additional avoidance space to avoid the first rotating member and the second rotating member installed on the base. This makes the structural strength of the support frame itself lower and is prone to breakage when overloaded. The base 610 in this embodiment can be located between the first side portion 6211 and the second side portion 6213 of the support frame 620, that is, the base 610 can be located on the inner side of the support frame 620. In this way, the first rotating member 630a and the second rotating member 630b will not interfere with the support frame 620, and the support frame 620 does not need to be provided with an additional avoidance space to avoid the first rotating member 630a and the second rotating member 630b, which is beneficial to improve the structural strength of the support frame 620 and extend the service life of the rotating mechanism 600.

[0393] In other embodiments, the torsion structure 630 may include n rotating parts. Each rotating part may include a rotating shaft and a gear sleeved and fixed to the rotating shaft. The structure of each rotating part can refer to the structure of the first rotating part 630a and will not be repeated here. Multiple rotating parts can be mounted on the base 610 and arranged in sequence along the length extension direction of the rotating mechanism 600. The gears of two adjacent rotating parts can mesh with each other. The number of torsion parts 630c can be one or more. At this time, the total torque M of the rotating mechanism 600 can be:

[0394]

[0395] Figure 75 yes Figure 57 The illustrated structure diagram of the rotating mechanism 600 in another embodiment is a schematic diagram of the structure of the rotating mechanism 600 in a closed state. Figure 76 yes Figure 75 FIG. 6 is a schematic diagram of the exploded structure of the rotating mechanism 600 shown in FIG. Figure 77 yes Figure 76 The structure diagram of the transmission member 622 of the support frame 620 shown is from another perspective.

[0396] like Figures 75 to 77 As shown, the structure of the rotating mechanism 600 in this embodiment is similar to Figure 57 The structure of the rotating mechanism 600 is substantially the same as that of the rotating mechanism 600 shown in FIG. Figure 57 Different features of the rotation mechanism 600 are shown.

[0397] Illustratively, the first gear 6223 of the transmission member 622 of the carrier 620 may include an engaging portion 6223a and a non-engaging portion 6223b sequentially connected along a circumferential direction thereof. Figure 76The meshing portion 6223a and the non-meshing portion 6223b are schematically demarcated by dotted lines. The meshing portion 6223a of the first gear 6223 may include a plurality of first meshing teeth 62231 for meshing with other gears. The outer side surface of the non-meshing portion 6223b of the first gear 6223 may include a first surface 62232, a second surface 62233, and a third surface 62234. There is a step difference between the first surface 62232 and the second surface 62233. The third surface 62234 may be connected between the first surface 62232 and the second surface 62233. That is, the non-meshing portion 6223b may be roughly a stepped structure. The first surface 62232, the second surface 62233, and the third surface 62234 may enclose an avoidance groove 62235.

[0398] For example, the first surface 62232 may be a cylindrical surface. The central axis of the first surface 62232 may coincide with the central axis of the first gear 6223. The radius of the cylindrical surface on which the first surface 62232 is located may be a first radius. The first radius may be less than or equal to the root circle radius of the meshing portion 6223a. In other embodiments, the first surface 62232 may also have other shapes. In this case, the distance between any point on the first surface 62232 and the central axis of the first gear 6223 may be less than the root circle radius of the meshing portion 6223a.

[0399] For example, the second surface 62233 may be a cylindrical surface. The central axis of the second surface 62233 may coincide with the central axis of the first gear 6223. The radius of the cylindrical surface on which the second surface 62233 is located may be a second radius. The second radius may be larger than the root circle radius of the meshing portion 6223a and smaller than the tip circle radius of the meshing portion 6223a.

[0400] Figure 78 yes Figure 76 The structure diagram of the first rotating member 630a and the second rotating member 630b of the torsion structure 630 shown is from another perspective.

[0401] like Figure 76 and Figure 78 As shown, the second gear 632 of the first rotating member 630a may include a first sub-gear 632a and a second sub-gear 632b. The first sub-gear 632a and the second sub-gear 632b may be sleeved and fixed to the first rotating shaft 631. The first sub-gear 632a may be fixedly connected to the second sub-gear 632b. For example, the first sub-gear 632a may be located on the side of the second sub-gear 632b facing the first end surface 6311 of the first rotating shaft 631. It should be understood that Figure 76 and Figure 78The first sub-gear 632a and the second sub-gear 632b are schematically demarcated by dotted lines. It should be noted that although the second gear 632 is described as being divided into two parts (i.e., the first sub-gear 632a and the second sub-gear 632b) in this embodiment, this does not affect the fact that the first sub-gear 632a and the second sub-gear 632b are integrally formed, that is, the second gear 632 can be an integrally formed structure.

[0402] For example, the first sub-gear 632a may include a first special-shaped tooth 6321 and a plurality of first sub-meshing teeth 6322 spaced apart along its circumference. The tooth top surface of the first special-shaped tooth 6321 may be a cylindrical surface. The central axis of the tooth top surface of the first special-shaped tooth 6321 and the central axis of the second gear 632 may be located on opposite sides of the tooth top surface of the first special-shaped tooth 6321. The distance between any point on the tooth top surface of the first special-shaped tooth 6321 and the central axis of the second gear 632 may be less than the tooth top circle radius of the first sub-meshing tooth 6322.

[0403] Exemplarily, the second sub-gear 632b may include a plurality of second sub-meshing teeth 6323 spaced apart along its circumference. The second sub-meshing teeth 6323 may be exactly the same in shape and size as the first sub-meshing teeth 6322. A portion of the plurality of second sub-meshing teeth 6323 may be fixedly connected to the plurality of first sub-meshing teeth 6322 in a one-to-one correspondence, and together with the plurality of first sub-meshing teeth 6322, form a plurality of second meshing teeth 632c of the second gear 632. Another portion of the plurality of second sub-meshing teeth 6323 may be fixedly connected to the first special-shaped tooth 6321. At this time, there is a step difference between the first special-shaped tooth 6321 and the second sub-meshing tooth 6323, and the two may form a stepped structure. Exemplarily, the first special-shaped tooth 6321 may be fixedly connected to two second sub-meshing teeth 6323.

[0404] Please refer again Figure 76 and Figure 78 The third gear 634 of the second rotating member 630b may include a third sub-gear 634a and a fourth sub-gear 634b. The third sub-gear 634a and the fourth sub-gear 634b may be sleeved and fixed to the second rotating shaft 633. The third sub-gear 634a may be fixedly connected to the fourth sub-gear 634b. For example, the third sub-gear 634a may be located on the side of the fourth sub-gear 634b facing the first end surface 6331 of the second rotating shaft 633. It should be understood that Figure 76 and Figure 78The third sub-gear 634a and the fourth sub-gear 634b are schematically demarcated by dotted lines. It should be noted that although the third gear 634 is described as being divided into two parts (i.e., the third sub-gear 634a and the fourth sub-gear 634b) in this embodiment, this does not affect the fact that the third sub-gear 634a and the fourth sub-gear 634b are integrally formed. In other words, the third gear 634 can be an integrally formed structure.

[0405] Exemplarily, the third sub-gear 634a may include a second special-shaped tooth 6341 and a plurality of third sub-meshing teeth 6342 spaced apart along its circumference. The tooth top surface of the second special-shaped tooth 6341 may be a cylindrical surface. The central axis of the tooth top surface of the second special-shaped tooth 6341 may coincide with the central axis of the third gear 634. The tooth top circle radius of the second special-shaped tooth 6341 may be smaller than the tooth top circle radius of the third sub-meshing tooth. In other embodiments, the tooth top surface of the second special-shaped tooth 6341 may also be other shapes. In this case, the distance between any point on the tooth top surface of the second special-shaped tooth 6341 and the central axis of the third gear 634 may be smaller than the tooth top circle radius of the third sub-meshing tooth.

[0406] Exemplarily, the fourth sub-gear 634b may include a plurality of fourth sub-meshing teeth 6343 spaced apart along its circumference. The shape and size of the fourth sub-meshing teeth 6343 and the third sub-meshing teeth 6342 may be exactly the same. A portion of the plurality of fourth sub-meshing teeth 6343 may be fixedly connected to the plurality of third sub-meshing teeth 6342 in a one-to-one correspondence, and together with the plurality of third sub-meshing teeth 6342 constitute the third meshing teeth 634c of the plurality of third gears 634. Another portion of the plurality of fourth sub-meshing teeth 6343 may be fixedly connected to the second special-shaped tooth 6341. At this time, there is a step difference between the second special-shaped tooth 6341 and the fourth sub-meshing tooth 6343, and the two may form a stepped structure. Exemplarily, the second special-shaped tooth 6341 may be fixedly connected to a fourth sub-meshing tooth 6343.

[0407] Figure 79 yes Figure 75 The illustrated diagram is a cross-sectional structural diagram of a rotating mechanism 600 in one embodiment, taken along D9-D9. Figure 80 yes Figure 75 The illustrated diagram is a cross-sectional structural diagram of a rotating mechanism 600 in one embodiment, taken along D10-D10.

[0408] like Figure 79 and Figure 80As shown, when the rotating mechanism 600 is in the closed state, the angle between the support frame 620 and the base 610 can be 0°. At this time, the support frame 620 can also be considered to be open at a first angle relative to the base 610, the first angle being 0°. The meshing portion 6223a of the first gear 6223 of the support frame 620 can be spaced apart from the second gear 632 of the first rotating member 630a. The non-meshing portion 6223b of the first gear 6223 can be disposed opposite the second gear 632. The first sub-gear 632a of the second gear 632 can be disposed opposite the second surface 62233 of the non-meshing portion 6223b. The second sub-gear 632b of the second gear 632 can be disposed opposite the first surface 62232 of the non-meshing portion 6223b. The second sub-meshing teeth 6323 of the second sub-gear 632b can be located within the avoidance groove 62235 of the non-meshing portion 6223b.

[0409] For example, the first special-shaped tooth 6321 of the first sub-gear 632a can be arranged opposite the non-meshing portion 6223b of the first gear 6223. The tooth top surface of the first special-shaped tooth 6321 can be arranged to face the second surface 62233 of the non-meshing portion 6223b. The tooth top surface of the first special-shaped tooth 6321 can be parallel to the second surface 62233 of the non-meshing portion 6223b. In other words, the shape of the tooth top surface of the first special-shaped tooth 6321 can be adapted to the shape of the second surface 62233 of the non-meshing portion 6223b.

[0410] Exemplarily, the tooth top surface of the first special-shaped tooth 6321 may contact the second surface 62233 of the non-meshing portion 6223b. Alternatively, the tooth top surface of the first special-shaped tooth 6321 may be spaced apart from the second surface 62233 of the non-meshing portion 6223b. In this case, the gap between the two may be less than or equal to 0.05 mm. Exemplarily, the distance between the tooth top surface of the first special-shaped tooth 6321 and the second surface 62233 of the non-meshing portion 6223b may be in the range of 0.03 mm to 0.05 mm. In this way, the gap between the tooth top surface of the first special-shaped tooth 6321 and the second surface 62233 of the non-meshing portion 6223b of the first gear 6223 is smaller. When the rotating mechanism 600 is in the closed state, the second surface 62233 can limit the tooth top surface of the first special-shaped tooth 6321. This prevents the first rotating member 630a from rotating at a large angle when the rotating mechanism 600 is in the closed state, which could cause the first gear 6223 of the support frame 620 to be unable to engage with the second gear 632 of the first rotating member 630a when the support frame 620 of the rotating mechanism 600 is opened relative to the base 610. Furthermore, a gap is provided between the tooth top surface of the first special-shaped tooth 6321 and the second surface 62233 of the non-engaging portion 6223b to facilitate assembly.

[0411] For example, the first sub-gear 632a of the second gear 632 may mesh with the third sub-gear 634a of the third gear 634. The second sub-gear 632b of the second gear 632 may mesh with the fourth sub-gear 634b of the third gear 634. The tooth top surface of the first special-shaped tooth 6321 of the second gear 632 may be parallel to the tooth top surface of the third special-shaped tooth of the third gear 634. The tooth top surface of the second special-shaped tooth 6341 of the second gear 632 may be parallel to the tooth top surface of the fourth special-shaped tooth of the third gear 634.

[0412] Figure 81 yes Figure 80 The structure shown is a schematic diagram of the structure when the support frame 620 is opened to a second angle relative to the base 610. Figure 82 yes Figure 80 The support frame 620 shown is a schematic structural diagram of the structure opened to a third angle relative to the base 610.

[0413] like Figure 81 and Figure 82 As shown, the opening state of the rotating mechanism 600 may include multiple states, for example, a first state and a second state. When the rotating mechanism 600 is in different states, the angle at which the support frame 620 is opened relative to the base 610 is different.

[0414] like Figures 79 to 81 As shown, when the rotating mechanism 600 is in the first state, the support frame 620 can be opened to a second angle relative to the base 610. At this time, the first meshing tooth 62231 closest to the second gear 632 in the meshing portion 6223a of the first gear 6223 can contact the first special-shaped tooth 6321 of the second gear 632 and the second sub-meshing tooth 6323 connected to the first special-shaped tooth 6321. At this time, the first gear 6223 can mesh with the second gear 632.

[0415] For example, when the rotation mechanism 600 switches from the closed state to the first state, the support frame 620 can rotate relative to the base 610, driving the first gear 6223 to rotate, so that the meshing portion 6223a of the first gear 6223 gradually approaches the first special-shaped tooth 6321 of the second gear 632. During this process, the first rotating member 630a and the second rotating member 630b can both remain stationary. In other words, the first rotating member 630a, the second rotating member 630b, and the torsion member 630c do not rotate relative to each other. In other words, when the support frame 620 is opened to the first angle relative to the base 610, the torsion structure 630 does not generate torque. The force required to rotate the support frame 620 relative to the base 610 is relatively small.

[0416] like Figure 81 and Figure 82As shown, when the rotating mechanism 600 is in the second state, the support frame 620 can be opened to a third angle relative to the base 610. The third angle can be greater than the second angle. At this time, the first special-shaped tooth 6321 of the second gear 632 can be arranged opposite to the second special-shaped tooth 6341 of the third gear 634. The tooth top surface of the first special-shaped tooth 6321 can be arranged facing the tooth top surface of the second special-shaped tooth 6341. There is a gap between the tooth top surface of the first special-shaped tooth 6321 and the tooth top surface of the second special-shaped tooth 6341. The second special-shaped tooth 6341 can be used to avoid the first special-shaped tooth 6321. The second sub-gear 632b can be meshed with the fourth sub-gear 634b.

[0417] For example, when the rotating mechanism 600 switches from the first state to the second state, the support frame 620 can rotate relative to the base 610, and the first gear 6223 of the support frame 620 can always remain in mesh with the second gear 632. The first gear 6223 can drive the second gear 632 to rotate, so that the first rotating member 630a rotates relative to the torsion member 630c and generates torque. The second sub-gear 632b can always remain in mesh with the fourth sub-gear 634b (please refer to the Figure 79 (as shown). That is, the second gear 632 can remain meshed with the third gear 634. The second gear 632 can drive the third gear 634 to rotate, causing the second rotating member 630b to rotate relative to the torsion member 630c, generating a torque. In other words, after the support frame 620 is opened to the second angle relative to the base 610, the force required to rotate the support frame 620 relative to the base 610 is greater as the opening and closing angle of the rotation mechanism 600 continues to increase.

[0418] It will be appreciated that the first gear 6223 of the support frame 620 in this embodiment includes an engaging portion 6223a and a non-engaging portion 6223b. When the rotating mechanism 600 is in the closed state, the engaging portion 6223a of the first gear 6223 can be spaced apart from the second gear 632. The non-engaging portion 6223b of the first gear 6223 can be positioned opposite the second gear 632. When the support frame 620 is opened to the first angle relative to the base 610, the support frame 620 can rotate relative to the base 610, driving the first gear 6223 to rotate. The first gear 6223 does not engage with the second gear 632, meaning that the second gear 632 does not rotate with the rotation of the first gear 6223. Thus, relative rotation between the first and second rotating members 630a, 630b, and the torsion member 630c does not occur, and the torsion structure 630 does not generate torque, thereby reducing the force required to open the support frame 620 relative to the base 610 to the first angle. When the support frame 620 is opened to a first angle relative to the base 610, the first meshing tooth 62231 of the meshing portion 6223a of the first gear 6223 can contact and mesh with the second gear 632. As the opening and closing angle of the rotation mechanism 600 continues to increase (i.e., when the angle of the support frame 620 relative to the base 610 is greater than the first angle), the first gear 6223 can maintain its meshing with the second gear 632, driving the second gear 632 to rotate, causing the first rotating member 630a to rotate relative to the torsion member 630c and generating torque. In this way, after the support frame 620 is opened to the first angle relative to the base 610, further opening requires a greater force. In other words, the rotation mechanism 600 in this embodiment can prevent the first rotating member 630a from rotating when the support frame 620 is opened to a smaller angle, preventing the torsion member 630 from generating torque. This reduces the force required to open and close the support frame 620, improving the user's opening and closing experience.

[0419] Secondly, in this embodiment, the second gear 632 may include a first special-shaped tooth 6321 and a plurality of first sub-meshing teeth 6322 spaced apart along its circumference. The distance between the tooth top surface of the first special-shaped tooth 6321 and the central axis of the second gear 632 is less than the tooth top circle radius of the first sub-meshing tooth 6322. The tooth top surface of the first special-shaped tooth 6321 is a cylindrical surface. The central axis of the tooth top surface of the first special-shaped tooth 6321 and the central axis of the first gear 6223 may be located on opposite sides of the tooth top surface of the first special-shaped tooth 6321. When the rotating mechanism 600 is in the closed state, the first special-shaped tooth 6321 may be arranged opposite the non-meshing portion 6223b of the first gear 6223. The tooth top surface of the first special-shaped tooth 6321 may be parallel to the outer surface of the non-meshing portion 6223b of the first gear 6223. The distance between the first special-shaped tooth 6321 and the non-meshing portion 6223b may be less than or equal to 0.05 mm. In this way, when the rotating mechanism 600 is in a closed state, or the rotating mechanism 600 is in an open state and the angle at which the support frame 620 is opened relative to the base 610 is smaller than the first angle, the distance between the tooth top surface of the first special-shaped tooth 6321 and the outer side surface of the non-meshing part 6223b is smaller, so that the non-meshing part 6223b can also limit the first special-shaped tooth 6321, thereby preventing the second gear 632 from rotating without being engaged with the first gear 6223, resulting in the problem that the meshing part 6223a of the first gear 6223 cannot be engaged with the second gear 632.

[0420] In addition, the third gear 634 in this embodiment may include a second special-shaped tooth 6341 and a plurality of third sub-meshing teeth 6342 spaced apart along its circumference. The distance between the tooth top surface of the second special-shaped tooth 6341 and the central axis of the third gear 634 is less than the tooth top circle radius of the third sub-meshing tooth 6342. When the rotating mechanism 600 is in a closed state, the first sub-meshing tooth 6322 of the second gear 632 may contact the third sub-meshing tooth 6342 of the third gear 634, that is, the second gear 632 may mesh with the third gear 634. When the support frame 620 is opened to a second angle relative to the base 610, the first special-shaped tooth 6321 of the second gear 632 may be arranged facing the second special-shaped tooth 6341 of the third gear 634. The second special-shaped tooth 6341 may be used to avoid the first special-shaped tooth 6321. In this way, when the second gear 632 rotates, it can also drive the third gear 634 to rotate, so that the second rotating member 630b rotates relative to the torsion member 630c and generates torque, thereby better meeting the high torque requirement. At the same time, the second special-shaped tooth 6341 can be used to avoid the first special-shaped tooth 6321 to prevent the second gear 632 and the third gear 634 from getting stuck when they rotate relative to each other.

[0421] Furthermore, the second gear 632 may include a first sub-gear 632a and a second sub-gear 632b. Both the first sub-gear 632a and the second sub-gear 632b may be mounted on and fixed to the first rotating shaft 631. A first special-shaped tooth 6321 and a plurality of first sub-meshing teeth 6322 may be located on the first sub-gear 632a. The second sub-gear 632b may include a plurality of second sub-meshing teeth 6323. The third gear 634 may include a third sub-gear 634a and a fourth sub-gear 634b. Both the third sub-gear 634a and the fourth sub-gear 634b may be mounted on and fixed to the second rotating shaft 633. A second special-shaped tooth 6341 and a plurality of third sub-meshing teeth 6342 may be formed on the third sub-gear 634a. The fourth sub-gear 634b may include a plurality of fourth sub-meshing teeth 6343 spaced circumferentially therefrom. The fourth sub-gear 634b may always remain meshed with the second sub-gear 632b. Thus, when the support frame 620 is opened to the second angle relative to the base 610, the second sub-gear 632b can still be meshed with the fourth sub-gear 634b. Thus, by setting the second sub-gear 632b of the second gear 632 to be meshed with the fourth sub-gear 634b of the third gear 634, the second gear 632 can remain meshed with the third gear 634 regardless of the state of the rotating mechanism 600. This prevents the second gear 632 from being disengaged from the third gear 634 when the second gear 632 rotates to the point where the first special-shaped tooth 6321 faces the second special-shaped tooth 6341. This would cause the third gear 634 to not rotate with the second gear 632, resulting in a sudden change in the torque of the torsion structure 630 and affecting the user's opening and closing experience.

[0422] In some embodiments, please refer to Figure 78 、 Figure 80 as well as Figure 83 , Figure 83 yes Figure 80The support frame 620 is shown as a schematic diagram of the structure in which the support frame 620 is opened to a third angle relative to the base 610. For example, the second gear 632 and the third gear 634 can be identical in shape and size. Specifically, the first sub-gear 632a can further include a third special-shaped tooth 6324. The third special-shaped tooth 6324 can be spaced apart from the first special-shaped tooth 6321 and the first sub-meshing tooth 6322. The third special-shaped tooth 6324 can be located between adjacent first special-shaped teeth 6321 and first sub-meshing teeth 6322, or between any two adjacent first sub-meshing teeth 6322. The third special-shaped tooth 6324 can be identical in shape and size to the second special-shaped tooth 6341. One or more of the second sub-meshing teeth 6323 can be fixedly connected to the third special-shaped tooth 6324. In this case, there is a step difference between the second sub-meshing teeth 6323 and the third special-shaped tooth 6324, and the two can form a stepped structure. For example, the third special-shaped tooth 6324 may be located between any two adjacent first sub-engaging teeth 6322. In this case, the third special-shaped tooth 6324 may not be adjacent to the first special-shaped tooth 6321.

[0423] The third sub-gear 634a may further include a fourth special-shaped tooth 6344. The fourth special-shaped tooth 6344 may be spaced apart from the second special-shaped tooth 6341 and the third sub-meshing tooth 6342. The fourth special-shaped tooth 6344 may be located between adjacent second special-shaped teeth 6341 and third sub-meshing teeth 6342, or between any two adjacent third sub-meshing teeth 6342. The fourth special-shaped tooth 6344 may be identical in shape and size to the first special-shaped tooth 6321. One or more of the fourth sub-meshing teeth 6343 may be fixedly connected to the fourth special-shaped tooth 6344. In this case, a step difference exists between the fourth sub-meshing tooth 6343 and the fourth special-shaped tooth 6344, forming a stepped structure. For example, the fourth special-shaped tooth 6344 may be located between any two adjacent third sub-meshing teeth 6342. In this case, the fourth special-shaped tooth 6344 may not be adjacent to the second special-shaped tooth 6341.

[0424] For example, when the rotating mechanism 600 is in the closed state, the tooth top surface of the first special-shaped tooth 6321 can be parallel to the tooth top surface of the fourth special-shaped tooth 6344. The tooth top surface of the second special-shaped tooth 6341 can be parallel to the tooth top surface of the third special-shaped tooth 6324. The open state of the rotating mechanism 600 can also include a third state. When the rotating mechanism 600 is in the third state, the support frame 620 can be opened to a third angle relative to the base 610. The third angle can be greater than the first angle and less than the second angle. At this time, the third special-shaped tooth 6324 can be arranged opposite to the fourth special-shaped tooth 6344. The tooth top surface of the third special-shaped tooth 6324 can be arranged to face the tooth top surface of the fourth special-shaped tooth 6344. There is a gap between the tooth top surface of the third special-shaped tooth 6324 and the tooth top surface of the fourth special-shaped tooth 6344. The third special-shaped tooth 6324 can be used to avoid the fourth special-shaped tooth 6344. In other words, during the relative rotation of the second gear 632 and the third gear 634 , the movement of the third special-shaped tooth 6324 and the movement of the fourth special-shaped tooth 6344 will not interfere with each other.

[0425] It can be understood that the second gear 632 and the third gear 634 in this embodiment are exactly the same in shape and size, so that the second gear 632 and the third gear 634 can be prepared using the same mold, which is conducive to simplifying the preparation process and improving the preparation accuracy.

[0426] In other embodiments, the second gear 632 may not include the third special-shaped tooth 6324 , and the third gear 634 may not include the fourth special-shaped tooth 6344 .

[0427] Figure 84 yes Figure 57 The illustrated structure diagram of the rotating mechanism 600 in yet another embodiment is a schematic diagram of the structure of the rotating mechanism 600 in a closed state. Figure 85 yes Figure 84 FIG. 6 is a schematic diagram of the exploded structure of the rotating mechanism 600 shown in FIG. Figure 86 yes Figure 85 The illustrated torsion member 630c is a schematic diagram of the assembly structure in some embodiments.

[0428] like Figures 84 to 86 As shown, the structure of the rotating mechanism 600 in this embodiment is similar to Figure 57 The structure of the rotating mechanism 600 is substantially the same as that of the rotating mechanism 600 shown in FIG. Figure 57 Different features of the rotation mechanism 600 are shown.

[0429] For example, the torsion member 630c of the torsion structure 630 may include a concave cam 637, a first elastic member 638, and a second elastic member 639. The concave cam 637 may include a first end 6371 and a second end 6372. The first end 6371 of the concave cam 637 may be provided with a first hole 6373. The second end 6372 of the concave cam 637 may be provided with a second hole 6374. The concave cam 637 may also include a first side surface 6375 and a second side surface 6376 disposed opposite to each other. The first hole 6373 and the second hole 6374 of the concave cam 637 may both penetrate the first side surface 6375 and the second side surface 6376.

[0430] For example, the first end 6371 of the concave cam 637 may be provided with a first groove 6377. The second end 6372 of the concave cam 637 may be provided with a second groove 6378. The openings of the first groove 6377 and the second groove 6378 may both be formed on the first side surface 6375 of the concave cam 637.

[0431] For example, the first elastic member 638 may have a third hole 6381. One end of the first elastic member 638 may contact the second side surface 6376 of the concave cam 637. In this case, the third hole 6381 of the first elastic member 638 may communicate with the first hole 6373 of the concave cam 637. The first hole 6373 and the third hole 6381 may together form the first through hole 6351 of the torsion member 630c. The first elastic member 638 and the first end 6371 of the concave cam 637 may together form the first end 635 of the torsion member 630c.

[0432] For example, the second elastic member 639 may have a fourth hole 6391. One end of the second elastic member 639 may contact the second side surface 6376 of the concave cam 637. In this case, the fourth hole 6391 of the second elastic member 639 may communicate with the second hole 6374 of the concave cam 637. The second hole 6374 and the fourth hole 6391 may together form the second through hole 6361 of the torsion member 630c. The second elastic member 639 and the second end 6372 of the concave cam 637 may together form the second end 636 of the torsion member 630c. The second elastic member 639 may be arranged side by side with the first elastic member 638.

[0433] For example, the first elastic member 638 and the second elastic member 639 can have the same shape and size. Both the first elastic member 638 and the second elastic member 639 can be coil springs. In other embodiments, the first elastic member 638 and the second elastic member 639 can also be other elastic structural members. In other embodiments, the torsion member 630c may not include the first elastic member 638 or the second elastic member 639.

[0434] Figure 87 yes Figure 85The structure diagram of the first rotating member 630a and the second rotating member 630b shown in another perspective. Figure 88 yes Figure 85 FIG. 6 is a schematic diagram of the assembly structure of the torsion structure 630 shown in FIG.

[0435] like Figure 84 、 Figure 87 by Figure 88 As shown, the first rotating member 630a may include a first protrusion 6301. The first protrusion 6301 may be fixedly connected to a surface of the second gear 632 facing the first end face 6311 of the first rotating shaft 631, that is, a surface of the second gear 632 facing the torsion member 630c. The second rotating member 630b may include a second protrusion 6302. The second protrusion 6302 may be fixedly connected to a surface of the third gear 634 facing the first end face 6331 of the second rotating shaft 633, that is, a surface of the third gear 634 facing the torsion member 630c.

[0436] For example, the first hole 6373 of the concave cam 637 and the third hole 6381 of the first elastic member 638 can both be fitted over the first rotating shaft 631 of the first rotating member 630a. In this case, one end of the first elastic member 638 can contact the second surface 6213a of the concave cam 637. The second hole 6374 of the concave cam 637 and the fourth hole 6391 of the second elastic member 639 can both be fitted over the second rotating shaft 633 of the second rotating member 630b. In this case, one end of the second elastic member 639 can contact the second surface 6213a of the concave cam 637.

[0437] Figure 89 yes Figure 84 The cross-sectional structure diagram of the rotating mechanism 600 in one embodiment is shown along D11-D11. Figure 90 yes Figure 89 The cross-sectional structure diagram of the rotating mechanism 600 is shown when the support frame 620 is opened to a second angle relative to the base 610.

[0438] like Figure 84 、 Figure 89 as well as Figure 90 As shown, both ends of the first rotating member 630a can be mounted on the base 610. Specifically, one end of the first rotating member 630a can be mounted on the second branch 615 of the base 610, and the other end can be mounted on the fourth branch 617 of the base 610. At this time, the end of the first elastic member 638 facing away from the concave cam 637 can contact the second branch 615 of the base 610. Under the action of the first elastic member 638, the first side surface 6375 of the concave cam 637 can maintain contact with the second gear 632.

[0439] For example, both ends of the second rotating member 630b can be mounted on the base 610. Specifically, one end of the second rotating member 630b can be mounted on the second branch 615 of the base 610, and the other end can be mounted on the fourth branch 617 of the base 610. At this time, the end of the second elastic member 639 facing away from the concave cam 637 can contact the second branch 615 of the base 610. Under the action of the second elastic member 639, the first side surface 6375 of the concave cam 637 can maintain contact with the third gear 634.

[0440] For example, when the angle between the support frame 620 and the base 610 is a first angle, the first protrusion 6301 of the first rotating member 630a can contact the first side surface 6375 of the concave cam 637. In this case, the length of the first elastic member 638 can be the first length. The second protrusion 6302 of the second rotating member 630b can contact the first side surface 6375 of the concave cam 637. In this case, the length of the second elastic member 639 can be a third length. The third length can be equal to the first length. For example, the first angle can be 0°. That is, when the rotating mechanism 600 is in the closed state, the first protrusion 6301 of the first rotating member 630a can contact the first side surface 6375 of the concave cam 637. The second protrusion 6302 of the second rotating member 630b can also contact the first side surface 6375 of the concave cam 637.

[0441] For example, when the included angle between the support frame 620 and the base 610 is the second angle, the first protrusion 6301 of the first rotating member 630a is located within the first groove 6377 of the concave cam 637. In this case, the length of the first elastic member 638 can be the second length. The first length can be smaller than the second length. The elastic force of the first elastic member 638 when the length is the first length can be greater than the elastic force when the length is the second length. Thus, when the first protrusion 6301 slides out of the first groove 6377, the first protrusion 6301 must exert a force on the concave cam 637, squeezing the concave cam 637 toward the first elastic member 638. The force exerted by the first protrusion 6301 on the concave cam 637 must overcome the elastic force of the first elastic member 638. In other words, the first elastic member 638 prevents the first protrusion 6301 from sliding out of the first groove 6377.

[0442] For example, when the angle between the support frame 620 and the base 610 is a first angle, the second protrusion 6302 of the second rotating member 630b can be located within the second groove 6378 of the concave cam 637. In this case, the length of the second elastic member 639 can be a fourth length. The fourth length can be equal to the second length. The third length can be less than the fourth length. The elastic force of the second elastic member 639 when the length is the third length can be greater than the elastic force when the length is the fourth length. Thus, when the second protrusion 6302 slides out of the second groove 6378, the second protrusion 6302 must exert a force on the concave cam 637, squeezing the concave cam 637 toward the second elastic member 639. The force exerted by the second protrusion 6302 on the concave cam 637 must overcome the elastic force of the second elastic member 639. In other words, the second elastic member 639 prevents the second protrusion 6302 from sliding out of the second groove 6378.

[0443] For example, the second angle can be greater than the first angle. When the support frame 620 is opened to the first angle relative to the base 610 and then continues to open to the second angle, the first protrusion 6301 can slide into the first groove 6377. The second protrusion 6302 can slide into the second groove 6378. At this time, if the support frame 620 continues to rotate relative to the base 610, causing the first protrusion 6301 to slide out of the first groove 6377 and the second protrusion 6302 to slide out of the second groove 6378, the first elastic member 638 will prevent the first protrusion 6301 from sliding out of the first groove 6377, and the second elastic member 639 will prevent the second protrusion 6302 from sliding out of the second groove 6378. In other words, the first elastic member 638 can cooperate with the concave cam 637 and the first rotating member 630a to provide torque for the support frame 620 to rotate relative to the base 610. The second elastic member 639 can cooperate with the concave cam 637 and the second rotating member 630 b to provide a torque for the support frame 620 to rotate relative to the base 610 .

[0444] It will be appreciated that the torque member 630c in this embodiment may include a concave cam 637 and a first elastic member 638. The first end 6371 of the concave cam 637 and the first elastic member 638 may both be mounted on the first rotating shaft 631 of the first rotating member 630a. The first rotating member 630a may be provided with a first protrusion 6301. The first protrusion 6301 may be fixed to the surface of the second gear 632 facing the concave cam 637. The first end 6371 of the concave cam 637 may be provided with a first groove 6377, with the opening of the first groove 6377 facing the second gear 632. When the support frame 620 rotates relative to the base 610, the first protrusion 6301 may slide into or out of the first groove 6377. In this way, under the action of the first elastic member 638, through the cooperation between the first protrusion 6301 and the first groove 6377, the torsion structure 630 can provide torque for the rotating mechanism 600 at the center axis of the first rotating member 630a when the support frame 620 is opened to a specific angle relative to the base 610, so as to meet the user's usage needs.

[0445] Secondly, the torque member 630c in this embodiment may further include a second elastic member 639. The second elastic member 639 may be located on the side of the concave cam 637 facing away from the third gear 634 and may be sleeved on the second rotating shaft 633. The second rotating member 630b may be provided with a second protrusion 6302. The second protrusion 6302 may be fixed to the surface of the third gear 634 facing the concave cam 637. The second end 6372 of the concave cam 637 may be provided with a second groove 6378. The opening of the second groove 6378 may face the third gear 634. When the support frame 620 rotates relative to the base 610, the second protrusion 6302 may slide into or out of the second groove 6378. Thus, under the action of the second elastic member 639, through the cooperation between the second protrusion 6302 and the second groove 6378, the torsion structure 630 can also provide torsion to the rotation mechanism 600 at the central axis of the second rotating member 630b when the support frame 620 is opened to a specific angle relative to the base 610, thereby increasing the total torsion of the entire rotation mechanism 600. Furthermore, the second rotating member 630b and the first rotating member 630a are arranged along the length of the rotation mechanism 600. In other words, the rotation mechanism 600 in this embodiment can achieve a thin design while maintaining high torsion, thereby facilitating a thin design for the entire electronic device.

[0446] In some embodiments, please refer again to Figure 86 and Figure 87The number of first grooves 6377 of the concave cam 637 can also be multiple. The multiple first grooves 6377 can be spaced apart around the central axis of the first hole 6373. The number of first protrusions 6301 of the first rotating member 630a can also be multiple. The multiple first protrusions 6301 can be spaced apart around the central axis of the first rotating shaft 631. The number of first grooves 6377 can be the same as the number of first protrusions 6301. In this embodiment, the number of first grooves 6377 and the number of first protrusions 6301 can both be three. In other embodiments, the number of first grooves 6377 and / or the number of first protrusions 6301 can also be other.

[0447] Please refer again Figure 89 and Figure 90 , when the support frame 620 is opened to the second angle relative to the base 610, the multiple first protrusions 6301 can slide into one of the first grooves 6377 one by one. When the support frame 620 continues to open relative to the base 610, the multiple first protrusions 6301 can slide out of the current first groove 6377 one by one. When the support frame 620 continues to open to the third angle relative to the base 610, the multiple first protrusions 6301 can slide into another first groove 6377 adjacent to the previous first groove 6377 one by one. The third angle can be greater than the second angle. In this way, through the cooperation between the multiple first protrusions 6301 and the multiple first grooves 6377, the first rotating member 630a and the torque member 630c can provide torque for the rotating mechanism 600 at multiple specific opening and closing angles during the rotation of the support frame 620 relative to the base 610, so as to meet the different usage needs of the user and improve the user experience. It should be noted that for the sake of simplicity of the drawings, Figure 86 In the following figures, only one of the first grooves 6377 and one of the first protrusions 6301 are marked.

[0448] In other embodiments, the number of first grooves 6377 and the number of first protrusions 6301 may be different. For example, the number of first protrusions 6301 may be one, and the number of first grooves 6377 may be multiple. Alternatively, the number of first protrusions 6301 may be multiple, and the number of first grooves 6377 may be one. This application does not specifically limit the number of first grooves 6377 or the number of first protrusions 6301.

[0449] In some embodiments, please refer again to Figure 86 、 Figure 87 、 Figure 89 as well as Figure 90, the number of second grooves 6378 can also be multiple. Multiple second grooves 6378 can be spaced apart around the central axis of the second hole 6374. The number of first grooves 6377 can be the same as the number of second grooves 6378. In this embodiment, the number of first grooves 6377 and the number of second grooves 6378 can both be three. The number of second protrusions 6302 can also be multiple. Multiple second protrusions 6302 can be spaced apart around the central axis of the second rotating shaft 633. The number of first protrusions 6301 can be the same as the number of second protrusions 6302. In this embodiment, the number of first protrusions 6301 and the number of second protrusions 6302 can both be three. The coordination between the multiple second protrusions 6302 and the multiple second grooves 6378 can refer to the coordination between the multiple first protrusions 6301 and the multiple first grooves 6377, and will not be repeated here. In this way, through the cooperation between the multiple second protrusions 6302 and the multiple second grooves 6378, when the support frame 620 rotates relative to the base 610, the second rotating member 630b and the torque member 630c can provide torque for the rotating mechanism 600 at multiple specific opening and closing angles, thereby meeting the different usage needs of users and improving the user experience. It should be noted that for the sake of simplicity of the drawings, Figure 87 In the figures and subsequent drawings, only one of the first protrusions 6301 and one of the second protrusions 6302 are marked. In other embodiments, the number of the first protrusions 6301 and the number of the second protrusions 6302 may be different.

Figure 92 yes Figure 91 The rotating mechanism 700 in some embodiments is shown as a schematic diagram of an exploded structure. For ease of understanding, the rotating mechanism 700 in this embodiment uses different reference numerals from the rotating mechanism 100 in the first embodiment.

[0451] like Figure 91 and Figure 92As shown, the rotating mechanism 700 can include an open state and a closed state. The rotating mechanism 700 may include a base 710, a support frame 720 and a self-opening and closing structure 760. The support frame 720 can be rotatably connected to the base 710. Specifically, the base 710 may include a first rotating body. The support frame 720 may include a second rotating body. The first rotating body of the base 710 can cooperate with the second rotating body of the support frame 720 so that the support frame 720 can rotate relative to the base 710, thereby enabling the rotating mechanism 700 to switch between the open state and the closed state. Specifically, one of the first rotating body and the second rotating body can be an arc-shaped chute, and the other can be an arc-shaped slider. In this embodiment, the first rotating body can be an arc-shaped slider, and the second rotating body can be an arc-shaped chute.

[0452] Figure 93 yes Figure 92 The shown schematic diagram is a structural diagram of the base 710 from another perspective.

[0453] like Figure 92 and Figure 93 As shown, some structural designs of the base 710 in this embodiment can refer to some structural designs of the base 110 in the first embodiment. For example, the base 710 may also include a second branch 715, a third branch 716, and a fourth branch 717 connected in sequence. The third branch 716 may be connected between the second branch 715 and the fourth branch 717. The second branch 715 may include a first inner side surface 7151 facing the fourth branch 717.

The second branch 715, the third branch 716, and the fourth branch 717 may enclose an inner space 710a of the base 710. The above structures may be substantially the same or similar to some of the structures of the base 110 in the first embodiment and will not be further described here. In some embodiments, the base 710 may also include a first branch (not shown). The first branch may be arranged opposite the third branch 716 and connect the second branch 715 and the fourth branch 717.

[0454] For example, the base 710 may further include a first protrusion 7152. The first protrusion 7152 may be fixed to the first inner side surface 7151 of the second branch 715. The shape of the first protrusion 7152 may be generally arc-shaped. The base 710 may further include a second protrusion 7172. The second protrusion 7172 may be fixed to the second inner side surface 7171 of the fourth branch 717. The shape of the second protrusion 7172 may be generally arc-shaped. The second protrusion 7172 may be disposed opposite the first protrusion 7152. The shape and size of the second protrusion 7172 may be the same as those of the first protrusion 7152. The first protrusion 7152 and the second protrusion 7172 may together constitute a first rotating body of the base 710.

[0455] For example, the first protrusion 7152 may include a first groove 7152a and a second groove 7152b. The opening of the first groove 7152a and the opening of the second groove 7152b may both be formed on the surface of the first protrusion 7152 facing the second protrusion 7172. The portion of the first protrusion 7152 between the first groove 7152a and the second groove 7152b may form a first transition portion 7152c. The surface of the first transition portion 7152c facing the second protrusion 7172 may be arcuate. The first transition portion 7152c may have a first top end 7152d. The distance between the first top end 7152d and the second inner side surface 7171 may be greater than the distance between the remaining portion of the first transition portion 7152c, excluding the first top end 7152d, and the second inner side surface 7171.

[0456] Illustratively, the second protrusion 7172 may include a third groove 7172a and a fourth groove 7172b. The openings of the third groove 7172a and the fourth groove 7172b may both be formed on the surface of the second protrusion 7172 facing the first protrusion 7152. The portion of the second protrusion 7172 between the third groove 7172a and the fourth groove 7172b may form a second transition portion 7172c. The surface of the second transition portion 7172c facing the first protrusion 7152 may be arcuate. The second transition portion 7172c may have a second top end 7172d. The distance between the second top end 7172d and the first inner side surface 7151 may be greater than the distance between the remaining portion of the second transition portion 7172c, excluding the second top end 7172d, and the first inner side surface 7151. Illustratively, the third groove 7172a of the second protrusion 7172 may be disposed opposite the first groove 7152a of the first protrusion 7152. The fourth groove 7172 b of the second bump 7172 may be disposed opposite to the second groove 7152 b of the first bump 7152 .

[0457] Figure 94 yes Figure 92 The structure diagram of the support frame 720 shown is from another perspective. Figure 95 yes Figure 94 The support frame 720 shown is a schematic diagram of a cross-sectional structure in one embodiment cut along E1-E1.

[0458] like Figure 92 、 Figure 94 as well as Figure 95As shown, some structural designs of the support frame 720 in this embodiment can refer to some structural designs of the support frame 120 in the first embodiment. For example, the support frame 720 can also include a first side surface 721 and a second side surface 722 arranged opposite to each other. The support frame 720 can be provided with a first sliding groove 723 and a second sliding groove 724. The opening of the first sliding groove 723 can be formed on the first side surface 721. The opening of the second sliding groove 724 can be formed on the second side surface 722. The above structures can be roughly the same as or similar to some structures of the support frame 120 in the first embodiment, and will not be repeated here. Among them, the first sliding groove 723 and the second sliding groove 724 can together constitute the second rotating body of the support frame 720.

[0459] For example, the support frame 720 may further include a communication hole 725 , which may connect the first sliding groove 723 and the second sliding groove 724 .

[0460] Figure 96 yes Figure 92 The structure diagram of the first telescopic slider 761 and the second telescopic slider 762 of the self-opening and closing structure 760 shown is shown in another perspective.

[0461] like Figure 92 and Figure 96 As shown, the self-opening and closing structure 760 may include a first telescopic slider 761 and a second telescopic slider 762. The first telescopic slider 761 may include a first end surface 7611 and a second end surface 7612 disposed opposite each other. The first telescopic slider 761 may be provided with a first mating groove 7613. The opening of the first mating groove 7613 may be formed on the first end surface 7611 of the first telescopic slider 761. The first mating groove 7613 may be arc-shaped. A first mating protrusion 7614 may be provided within the first mating groove 7613. The surface of the first mating protrusion 7614 facing the first end surface 7611 may be arc-shaped. The first mating protrusion 7614 may have a third top end 761a. The distance between the third top end 761a and the second end surface 7612 of the first telescopic slider 761 may be greater than the distance between the remainder of the first mating protrusion 7614, excluding the third top end 761a, and the second end surface 7612.

[0462] Illustratively, the second telescopic slider 762 may include a first end surface 7621 and a second end surface 7622 disposed opposite each other. The second telescopic slider 762 may be provided with a second mating groove 7623. The opening of the second mating groove 7623 may be formed on the first end surface 7621 of the second telescopic slider 762. The second mating groove 7623 may be arc-shaped. A second mating protrusion 7624 may be provided within the second mating groove 7623. The surface of the second mating protrusion 7624 facing the first end surface 7621 may be arc-shaped. The second mating protrusion 7624 may have a fourth top end 762a. The distance between the fourth top end 762a and the second end surface 7622 of the second telescopic slider 762 may be greater than the distance between the remaining portion of the second mating protrusion 7624, excluding the fourth top end 762a, and the second end surface 7622. Illustratively, the shape and size of the second telescopic slider 762 may be the same as those of the first telescopic slider 761.

[0463] Figure 97 yes Figure 92 The diagram shows the assembly structure of the support frame 720 and the self-opening and closing structure 760. Figure 98 yes Figure 97 The structure shown is a schematic diagram of a partial cross-section structure in one embodiment cut along E2-E2.

[0464] like Figure 92 、 Figure 97 as well as Figure 98 As shown, the self-opening and closing structure 760 may further include an elastic member 763. Exemplarily, the elastic member 763 may be a coil spring. The elastic member 763 may be mounted in the connecting hole 725 of the support frame 720. The first telescopic slider 761 and the second telescopic slider 762 may both be mounted in the connecting hole 725. The first telescopic slider 761 and the second telescopic slider 762 may be located on opposite sides of the elastic member 763. One end of the elastic member 763 may contact the second end surface 7612 of the first telescopic slider 761, and the other end of the elastic member 763 may contact the second end surface 7622 of the second telescopic slider 762. The first telescopic slider 761 may be arranged closer to the first sliding groove 723 than the second sliding groove 724.

[0465] For example, the shape of the first matching slot 7613 of the first telescopic slider 761 can match the shape of the first sliding slot 723 of the support frame 720 . The shape of the second matching slot 7623 of the second telescopic slider 762 can match the shape of the second sliding slot 724 of the support frame 720 .

[0466] Figure 99 yes Figure 91 The illustrated diagram is a cross-sectional structural diagram of a rotating mechanism 700 in one embodiment, taken along E3-E3. Figure 100 yes Figure 91The illustrated diagram is a cross-sectional structural diagram of a rotating mechanism 700 in one embodiment, taken along E4-E4. Figure 101 yes Figure 91 The illustrated diagram is a cross-sectional structural diagram of an embodiment of the rotating mechanism 700 taken along E5-E5.

[0467] like Figures 99 to 101 As shown, the first sliding groove 723 of the support frame 720 can be slidably connected to the first protrusion 7152 of the base 710. The second sliding groove 724 of the support frame 720 can be slidably connected to the second protrusion 7172 of the base 710. Under the action of the elastic member 763, the first telescopic slider 761 and the second telescopic slider 762 can respectively abut the first protrusion 7152 and the second protrusion 7172 of the base 710. At this time, the first mating groove 7613 of the first telescopic slider 761 can also be slidably connected to the first protrusion 7152 of the base 710. The second mating groove 7623 of the second telescopic slider 762 can also be slidably connected to the second protrusion 7172 of the base 710.

[0468] For example, when the rotating mechanism 700 is in the closed state, the angle between the support frame 720 and the base 710 can be 0°. In this case, the support frame 720 can also be considered to be open at a first angle relative to the base 710, which is 0°. The first mating protrusion 7614 of the first telescopic slider 761 can be located within the first groove 7152a of the first protrusion 7152. The second mating protrusion 7624 of the second telescopic slider 762 can be located within the third groove 7172a of the second protrusion 7172. In this case, the length of the elastic member 763 can be the first length.

[0469] Figure 102 yes Figure 99 The structure diagram shown is when the support frame 720 of the rotating mechanism 700 is opened to a second angle relative to the base 710. Figure 103 yes Figure 100 The structure diagram shown is when the support frame 720 of the rotating mechanism 700 is opened to a second angle relative to the base 710. Figure 104 yes Figure 101 The structure diagram shown is when the support frame 720 of the rotating mechanism 700 is opened to a second angle relative to the base 710.

[0470] like Figures 102 to 104As shown, the rotating mechanism 700 can also include an intermediate state between the open and closed states. For example, when the rotating mechanism 700 is in the intermediate state, the support frame 720 can be opened to a second angle relative to the base 710. The second angle can be greater than the first angle. At this point, the third tip 761a of the first mating protrusion 7614 of the first telescopic slider 761 can contact the first tip 7152d of the first protrusion 7152. The fourth tip 762a of the second mating protrusion 7624 of the second telescopic slider 762 can contact the second tip 7172d of the second protrusion 7172. At this point, the distance between the third tip 761a and the fourth tip 762a is minimized, and the length of the elastic member 763 can be a second length. The second length can be the minimum length of the elastic member, which is less than the first length. In other words, the second length can be a critical minimum length of the elastic member. The elastic force of the elastic member 763 at the second length can be greater than the elastic force when the elastic member 763 is at the first length. In other words, when the rotating mechanism 700 is in the intermediate state, relative to when the rotating mechanism 700 is in the closed state, the elastic member 763 can be considered to be in a compressed state.

[0471] Figure 105 yes Figure 99 The structure diagram shown is when the support frame 720 of the rotating mechanism 700 is opened to a third angle relative to the base 710. Figure 106 yes Figure 99 The structure diagram shown is when the support frame 720 of the rotating mechanism 700 is opened to a third angle relative to the base 710. Figure 107 yes Figure 99 The structure diagram shown is when the support frame 720 of the rotating mechanism 700 is opened to a third angle relative to the base 710.

[0472] like Figures 105 to 107 As shown, when the rotating mechanism 700 is in the open state, the support frame 720 can be opened to a third angle relative to the base 710. The third angle can be greater than the first and second angles. At this time, the first mating protrusion 7614 of the first telescopic slider 761 can be located in the second groove 7152b of the first protrusion 7152. The second mating protrusion 7624 of the second telescopic slider 762 can be located in the fourth groove 7172b of the second protrusion 7172. The length of the elastic member 763 can be a third length. The third length can be greater than the second length. The elastic force of the elastic member 763 when the length is the third length can be less than the elastic force when the length is the second length. For example, the third length can be equal to the first length.

[0473] like Figure 101 、 Figure 104 as well as Figure 107As shown, when the rotating mechanism 700 switches from a closed state to an open state, the support frame 720 can rotate relative to the base 710, driving the first telescopic slider 761 to slide relative to the first protrusion 7152, and driving the second telescopic slider 762 to slide relative to the second protrusion 7172. The first telescopic slider 761 can slide back and forth within the connecting hole 725 in cooperation with the first mating protrusion 7614 and the first protrusion 7152. The second telescopic slider 762 can slide back and forth within the connecting hole 725 in cooperation with the second mating protrusion 7624 and the second protrusion 7172. When the rotating mechanism 700 switches from a closed state to an intermediate state, both the first telescopic slider 761 and the second telescopic slider 762 can slide within the connecting hole 725 toward the elastic member 763, thereby compressing the elastic member 763. When the rotating mechanism 700 switches from the closed state to the intermediate state, that is, when the support frame 720 opens to the second angle relative to the base 710, the third top end 761a of the first telescopic slider 761 can contact the first top end 7152d of the first protrusion 7152. The fourth top end 762a of the second telescopic slider 762 can contact the second top ...
