Detailed Implementation

[0079] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0080] These embodiments are provided to make the disclosure thorough and complete, and to fully express the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, material composition, numerical expressions, and values ​​set forth in these embodiments should be interpreted as exemplary only and not as limiting.

[0081] It should be noted that, in the description of this disclosure, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," etc., indicating orientation or positional relationship are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must include a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0082] Furthermore, the terms "first," "second," and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. "Vertical" is not strictly vertical, but within the permissible margin of error. "Parallel" is not strictly parallel, but within the permissible margin of error. Terms such as "including" or "contains" mean that the element preceding the word encompasses the element listed after the word, and do not exclude the possibility of encompassing other elements as well.

[0083] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure depending on the specific circumstances. When a particular device is described as being located between a first device and a second device, an intermediary device may or may not be present between the particular device and the first or second device.

[0084] All terms used in this disclosure have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted to include meanings consistent with their meanings in the context of the relevant art, and not to be interpreted in an idealized or highly formalized sense, unless expressly defined herein.

[0085] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0086] The inventors discovered that in electronic devices such as laptops or foldable phones, the second body (e.g., the system unit, with input components like a keyboard) and the first body (e.g., the screen unit, with output components like a screen) are typically connected by a hinge structure. Due to structural requirements of some electronic devices (such as the need to arrange heat dissipation vents and interfaces on the rear of the second body), the hinge structure needs to be located on the functional surface of the second body where the keyboard is located (e.g., the C-side of the system unit). In this electronic device, the hinge structure usually remains in a fixed position. That is, during the switching between different forms of the first and second bodies, the first body rotates along the axis of the hinge structure, while the axis of the hinge structure remains in a fixed position relative to the second body. This hinge arrangement restricts the relative freedom of movement between the first and second bodies during the switching process, easily leading to interference between the first and second bodies in specific forms or the inability to achieve a tight fit between them in specific forms, thus affecting user needs in different usage scenarios. If the distance between the axis of the hinge structure and the functional surface of the second body could vary in different device forms, then user needs in different forms could be met.

[0087] Therefore, this application provides an electronic device. This electronic device movably mounts a hinge structure onto the second functional surface of a second body and rotatably connects it to the first body, allowing the distance between the axis of the hinge structure and the second functional surface to change during switching between the first and second device forms. In this way, without significant modifications to the structure of the first or second body, more flexible relative positional adaptation between the first and second bodies can be achieved in different device forms, thereby meeting the user's needs in different forms.

[0088] like Figure 1As shown, this application provides an electronic device. The electronic device includes a first body 10, a second body 20, and a hinge structure 30. In an embodiment where the electronic device is a laptop computer, the first body 10 may be the screen end of the laptop computer (having components such as a screen and / or camera), and the second body 20 may be the system end of the laptop computer (the host end, having components such as a motherboard and / or keyboard). The rear side 22 of the second body 20 is provided with heat dissipation vents and interfaces.

[0089] The first body 10 may include a first functional surface 11. In an embodiment where the first body 10 is a screen, the first functional surface 11 may be the surface where the screen is located, i.e., the front of the display screen. The second body 20 may include a second functional surface 21. In an embodiment where the second body 20 is a system, the second functional surface 21 may be the top surface (i.e., the C-surface) of the system, on which functional components such as keyboards and touchpads may be disposed.

[0090] The hinge structure 30 can be disposed on the second functional surface 21 and rotatably connects the first body 10 and the second body 20, allowing the first body 10 and the second body 20 to rotate relative to each other to achieve switching between a first device mode and a second device mode. The first device mode can be a mode where the angle between the first body 10 and the second body 20 is 0° or approximately 0°. The second device mode can be a mode where the angle between the first body 10 and the second body 20 is 180° or approximately 180°, or other angles, such as an angle between the first body 10 and the second body 20 of 90° or approximately 90°. In an embodiment where the electronic device is a laptop computer, the first device mode can be a closed mode of the laptop computer, and the second device mode can be an unfolded mode of the laptop computer (including unfolding to a certain angle (such as 60° or 90°), or fully unfolding to 180°, etc.). During the switching process, the relative positions of the first functional surface 11 and the second functional surface 21 can change accordingly. Furthermore, during the switching process, the first body 10 is located on the side of the orientation direction of the second functional surface 21, that is, along the projection parallel to the second functional surface 21, with the second functional surface 21 as the dividing line, the second body 20 is located on the dividing line and one side of the dividing line, and the first body 10 is located on the other side of the dividing line, so that the first body 10 and the second body 20 are respectively located on both sides of the plane where the second functional surface 21 is located.

[0091] The rotating shaft structure 30 can be positioned on the second functional surface 21, meaning it is located on one side of the second functional surface 21 of the second body 20, with the second functional surface 21 serving as a mounting reference surface or position reference surface. Specifically, the rotating shaft structure 30 is positioned on the side of the second functional surface 21 of the second body 20, ensuring a vertical distance between the axis 300 of the rotating shaft structure 30 and the plane containing the second functional surface 21. This allows the first body 10, rotatably connected to the rotating shaft structure 30, to be located on the side facing the second functional surface 21. Furthermore, during device configuration switching, the rotating shaft structure 30 can move relative to the second functional surface 21, allowing this vertical distance to change.

[0092] The rotating shaft structure 30 is rotatably connected to the first body 10, and the axis of rotation is the axis 300 of the rotating shaft structure 30. Since the rotating shaft structure 30 is movably disposed on the second functional surface 21, the rotating shaft structure 30 has different relative positions with respect to the second functional surface 21 through movement, so that the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21 varies in different device configurations.

[0093] In the first device configuration, the first functional surface 11 and the second functional surface 21 satisfy relative conditions. These relative conditions refer to a positional relationship between the first functional surface 11 and the second functional surface 21, such that they are face-to-face. This includes the first functional surface 11 and the second functional surface 21 being approximately parallel and facing each other, with the orientation of the first functional surface 11 being approximately opposite to the orientation of the second functional surface 21. In the first device configuration, the relative conditions also ensure that the first body 10 and the second body 20 are in a closed or substantially closed state. In an embodiment where the electronic device is a laptop computer, the first device configuration can be a state where the screen and keyboard surfaces overlap; or, in an embodiment where the electronic device is a foldable phone, the first device configuration can be a state where the two display surfaces are folded and fitted together.

[0094] In the first device configuration, the rotating shaft structure 30 can be positioned relative to the second functional surface 21 in a first relative position, such that the axis 300 of the rotating shaft structure 30 and the second functional surface 21 are at a first distance. In the second device configuration, the rotating shaft structure 30 is positioned relative to the second functional surface 21 in a second relative position, such that the axis 300 of the rotating shaft structure 30 and the second functional surface 21 are at a second distance. The first distance and the second distance are different.

[0095] In embodiments where the first distance is less than the second distance, the second distance can be larger than the first distance by a predetermined value (such as any value between 2.4 mm and 3 mm). For example, the first distance is 3 mm and the second distance is 6 mm; the first distance is 5 mm and the second distance is 7.5 mm, etc.

[0096] It is also possible to make the first distance greater than the second distance, for example, the first distance is 6.5mm and the second distance is 4mm; the first distance is 7mm and the second distance is 4.5mm, etc.

[0097] The relative position can refer to the spatial relationship between the entire rotating shaft structure 30 or the axis 300 of the rotating shaft structure 30 and the second functional surface 21. Specifically, the first relative position can refer to the spatial position of the rotating shaft structure 30 relative to the second functional surface 21 in the first device configuration; the second relative position can refer to the spatial position of the rotating shaft structure 30 relative to the second functional surface 21 in the second device configuration. The difference between the first and second relative positions is at least reflected in the different distances between the axis 300 of the rotating shaft structure 30 and the second functional surface 21. Furthermore, other differences may exist between the first and second relative positions, such as the same or different projection positions of the axis 300 of the rotating shaft structure 30 in a plane parallel to the second functional surface 21, or different tilt angles of the rotating shaft structure 30 relative to the second functional surface 21. The distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21 can be the vertical distance between the rotation center axis of the rotating shaft structure 30 (or its rotating shaft component 342) and the plane containing the second functional surface 21. This distance can be the shortest distance measured along the orientation direction of the second functional surface 21. When the second functional surface 21 is non-planar (e.g., curved, stepped, or with an uneven structure), this distance can be the vertical distance between the axis 300 of the rotating shaft structure 30 and the reference plane of the second functional surface 21 (e.g., the average plane of the second functional surface 21, the mating surface that mates with the first functional surface 11, or the plane containing the main surface of the second body 20). This distance can vary in different device configurations. The variation can include translating the axis 300 along a direction perpendicular to the second functional surface 21, moving the axis 300 along a direction inclined to the second functional surface 21, or rotating the axis 300 during movement, thereby changing the vertical distance from the axis 300 of the rotating shaft structure 30 to the second functional surface 21.

[0098] Furthermore, the first distance and the second distance are different. It can also be that the distance is smaller in the first device configuration and larger in the second device configuration, or that the distance is larger in the first device configuration and smaller in the second device configuration.

[0099] For example, in some embodiments, the first distance can be greater than the second distance. That is, in the first device configuration, the distance between the axis 300 of the pivot structure 30 and the second functional surface 21 is relatively large; in the second device configuration, this distance is relatively small, so that the first surface 13 and the second functional surface 21 can meet the contact condition or clearance fit condition, thereby achieving the stability of the first body 10 and the second body 20 in the unfolded state. Alternatively, the first distance is less than the second distance. That is, in the first device configuration, the distance between the axis 300 of the pivot structure 30 and the second functional surface 21 is relatively small; in the second device configuration, this distance is relatively large, so that in the unfolded state, the first body 10 (first surface 13) is far away from the second functional surface 21 and the rear side 22 of the second body 20, thereby giving the rear side of the second body 20 more space, which is beneficial for the air outlet of the rear side 22 and the plugging and unplugging of the interface, etc.

[0100] Since the rotating shaft structure 30 is movably disposed on the second functional surface 21, during the process of relative rotation between the first body 10 and the second body 20 to switch between different device forms, the rotating shaft structure 30 can follow the movement of the first body 10 and generate displacement relative to the second functional surface 21, so that the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21 changes accordingly.

[0101] That is, in different device configurations, the distance between the axis 300 of the pivot structure 30 and the second functional surface 21 can be adjusted by changing the position of the pivot structure 30 relative to the second functional surface 21. In the embodiment where the distance is increased (the first distance is less than the second distance), more clearance space is provided for the rotation of the first body 10, avoiding interference between the first body 10 and the second body 20 (including the second functional surface 21, the rear side 22, or structures such as heat dissipation vents and interfaces arranged on the rear side 22). In the embodiment where the distance is decreased (the first distance is greater than the second distance), the first surface 13 of the first body 10 and the second functional surface 21 can meet the contact condition or clearance fit condition, thereby improving the structural compactness of the first body 10 and the second body 20 in the unfolded state, which is beneficial to reducing the overall thickness of the electronic device. It can be understood that by adjusting the position of the pivot structure 30 relative to the second functional surface 21 according to the design requirements of the electronic device (including clearance requirements and / or fitting requirements, etc.), problems such as the inability to meet clearance requirements or fitting requirements due to the fixed position of the pivot structure 30 are avoided, thereby enabling the electronic device to meet the corresponding requirements in the corresponding configuration.

[0102] In some embodiments, the first body 10 may have a target portion 12. In a first device configuration, the target portion 12 obscures at least a portion of the pivot structure 30 along the second direction Z (perpendicular to the second functional surface 21). In a second device configuration, the second distance is greater than the first distance, that is, the distance between the axis 300 of the pivot structure 30 and the second functional surface 21 is increased.

[0103] That is, in the first device configuration (closed state, the angle between the first body 10 and the second body 20 can be 0°), the hinge structure 30 is in a lower position. The target portion 12 of the first body 10 can cover most of the area of ​​the hinge structure 30 (including the axis portion), thereby achieving a "hidden hinge" or "hinge-free" visual effect, improving the overall aesthetics of the electronic device 100 and providing dust protection.

[0104] In the second device configuration (the unfolded state, where the angle between the first body 10 and the second body 20 can be 180°), the pivot structure 30 rises to a higher position. This rise of the pivot structure 30 allows it to avoid the target portion 12, ensuring that the first body 10 and the second body 20 can unfold to a predetermined angle (such as 180° or 179°) without interference between the target portion 12 and the pivot structure 30.

[0105] That is, by changing the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21 under different device configurations, the target part 12 can cover the rotating shaft structure 30 in the first device configuration, and the rotating shaft structure 30 can move to avoid the target part 12, thereby achieving the operation of switching to the second device configuration (the first body 10 and the second body 20 unfold to a predetermined angle). The rotating shaft structure 30 is movably disposed on the second functional surface 21, meaning that the rotating shaft structure 30 can move relative to the second functional surface 21. This movement can be a non-fixed motion of the rotating shaft structure 30 relative to the second functional surface 21, including but not limited to translational motion (e.g., sliding along a straight line), rotational motion (e.g., rotating around a fixed point or axis), compound motion (e.g., both translation and rotation), motion along a target trajectory (e.g., motion along a guide groove or guide rail), or any combination of the above motions. The movable arrangement allows the rotating shaft structure 30 and the second functional surface 21 to not be relatively fixed, but rather to allow relative displacement or relative movement between them. To achieve a movable arrangement, the rotating shaft structure 30 and the second functional surface 21 can be connected by sliding contact between a slider and a slide rail, rotational contact between an eccentric wheel mechanism, hinged contact between a linkage mechanism, rolling contact between a roller and a guide groove, or deformation contact between a flexible hinge, etc., without specific limitations.

[0106] The rotating shaft structure 30 is slidably disposed on the second functional surface 21 through the cooperation of the slider and the slide rail. That is, the second functional surface 21 is provided with a slide rail extending in a predetermined direction, the rotating shaft structure 30 is provided with a slider that slides in cooperation with the slide rail, and the rotating shaft structure 30 slides along the slide rail during the switching process, thereby changing the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21.

[0107] The rotating shaft structure 30 can also be movably mounted on the second functional surface 21 via an eccentric wheel mechanism. That is, the rotating shaft structure 30 is rotatably mounted on the second functional surface 21 via an eccentric wheel, and there is an eccentricity between the rotation center of the eccentric wheel and the axis 300 of the rotating shaft structure 30. When the first body 10 and the second body 20 rotate relative to each other, the eccentric wheel rotates relative to the second functional surface 21, causing the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21 to change with the rotation angle of the eccentric wheel.

[0108] The rotating shaft structure 30 can also be movably mounted on the second functional surface 21 via a linkage mechanism. Specifically, the rotating shaft structure 30 is connected to the second functional surface 21 via at least one connecting rod, with one end of the connecting rod hinged to the second functional surface 21 and the other end hinged to the rotating shaft structure 30. During the switching process, the rotation of the first body 10 causes the connecting rod to swing, thereby changing the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21.

[0109] In some embodiments, in the first device configuration, the axis 300 of the rotating shaft structure 30 is in a first position relative to the second functional surface 21. In the second device configuration, the axis 300 of the rotating shaft structure 30 is in a second position relative to the second functional surface 21. During the transition from the first device configuration to the second device configuration, the axis 300 of the rotating shaft structure 30 changes from the first position to the second position. That is, during the transition between the first device configuration and the second device configuration, the angle between the first body 10 and the second body 20 changes, and this change in angle can cause the rotating shaft structure 30 to move relative to the second functional surface 21, so that the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21 changes accordingly.

[0110] This allows the position of the axis 300 of the rotating shaft structure 30 to change with the switching of the device form, so that the first body 10 and the second body 20 can automatically adjust the position of the axis 300 of the rotating shaft structure 30 without additional driving components during the switching process.

[0111] Since no additional drive components such as motors are required, the number of internal parts in the electronic device can be reduced, thereby lowering manufacturing costs and assembly complexity. Furthermore, by avoiding the need for additional internal space, more room can be provided for other components within the second body 20. For example, in an embodiment where the electronic device is a laptop, the second body 20 is the system unit, containing core components such as a battery and a heat dissipation module. The elimination of additional drive components allows for greater space for these components, thus contributing to improved battery life and heat dissipation performance.

[0112] It should be noted that in electronic devices that do not require additional driving components, the position of the axis 300 of the rotating shaft structure 30 can be changed without setting up additional driving components. Alternatively, additional driving components can be set up in the electronic device.

[0113] In embodiments where additional drive components (such as motors, cylinders, or electromagnetic actuators) are provided, the position of the axis 300 of the rotating shaft structure 30 can be adjusted accordingly using these drive components. By providing independent drive components, the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21 can be actively controlled according to the usage scenario in different device configurations. This makes the distance adjustment no longer dependent on the rotation angle between the first body 10 and the second body 20, thereby increasing the freedom and flexibility of adjusting the position of the axis 300. For example, in scenarios requiring a larger heat dissipation space, the distance between the axis 300 and the second functional surface 21 can be actively increased using this drive component, thereby increasing the gap between the first body 10 and the second body 20 to improve heat dissipation efficiency. In scenarios requiring a thin and portable design, the distance between the axis 300 and the second functional surface 21 can be actively decreased using the drive component, thereby decreasing the gap between the first body 10 and the second body 20 to reduce the overall thickness (the dimension in the arrangement direction of the first body 10 and the second body 20). Furthermore, the active drive method can adapt to more device configuration requirements.

[0114] like Figures 1-6 As shown, in some embodiments, the rotating shaft structure 30 further includes a first support 31, a second support 32, a third support 33, and a transmission assembly 34. The first support 31 is connected to the first body 10. The second support 32 is connected to the second body 20. The first support 31 rotates relative to the third support 33 along the axis 300 of the rotating shaft structure 30. The third support 33 and the second support 32 move relative to each other along a first direction X, the first direction X being perpendicular to the second functional surface 21. Figure 2 The first direction X (in the horizontal direction) forms a target angle (for example, the first direction X can be perpendicular to the second functional surface 21, or it can form other predetermined angles with the second functional surface 21). The transmission assembly 34 transmits power to the first bracket 31, the second bracket 32, and the third bracket 33.

[0115] The first direction X can be the direction in which the third support 33 moves relative to the second support 32. The first direction X and the second functional surface 21 can form a target angle, which can be 90° (i.e., the first direction X is perpendicular to the second functional surface 21), or it can be an acute angle or an obtuse angle (i.e., the first direction X is inclined to the second functional surface, such as 30°, 45°, 120°, or 135°). In different implementations or different movement stages, the first direction X can remain constant or change dynamically according to the movement trajectory.

[0116] The second support 32 can be a split structure, comprising a first sub-support 321 and a second sub-support 322. The first sub-support 321 and the second sub-support 322 can be clamped on both sides of the third support 33. At least one of the first sub-support 321 and the second sub-support 322 is provided with a sliding structure that cooperates with the third support 33. This sliding structure can guide the third support 33 to slide along a first direction X. This sliding structure can be a groove and slider cooperation structure. Because the second support 32 can be a split structure, it facilitates the assembly of the third support 33 with the second support 32.

[0117] For example, in some embodiments, the first direction X is perpendicular to the second functional surface 21, and the third support 33 moves up and down along this direction to change the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21. In other embodiments, the first direction X is an inclined direction at a 45° angle to the second functional surface 21, and the third support 33 moves obliquely along this direction to change the vertical distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21, and the projected position in a plane parallel to the second functional surface 21. The specific angle of the first direction X can be designed according to the actual spatial layout and the desired motion trajectory, and the extension direction of components such as the mating rack or sliding mating part provided on the second support 32 can be adjusted according to the specific angle of the first direction X. During the switching between the first device form and the second device form, the first support 31 rotates relative to the third support 33, and the transmission assembly 34 drives the third support 33 to move relative to the second support 32 along the first direction X, so as to change the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21. Since the first bracket 31, the second bracket 32 ​​and the third bracket 33 are linked through the transmission component 34, when the first body 10 rotates, the rotation of the first bracket 31 can be converted into the linear motion of the third bracket 33 relative to the second bracket 32 ​​along the first direction X through the transmission component 34. This realizes the automatic adjustment of the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21. The distance change can be completed without setting an independent drive source, thus reducing cost and structural complexity.

[0118] The transmission assembly 34 can connect the first bracket 31, the second bracket 32, and the third bracket 33 in a manner that can be a gear set 346 structure or a worm gear structure of the second transmission mating component 341, etc. No specific restrictions are imposed here; it is only necessary that the rotation of the first bracket 31 drives the third bracket 33 to move relative to the second bracket 32 ​​along the first direction X through the transmission assembly 34.

[0119] In other embodiments, the transmission assembly 34 may include a flexible transmission element (e.g., a wire rope, belt, or chain). Rotation of the first support 31 drives the third support 33 to move relative to the second support 32 along a first direction X via the flexible transmission element.

[0120] Alternatively, the third support 33 can be omitted. The transmission assembly 34 may include a cam mechanism. The first support 31 can rotate relative to the first body 10 along the axis 300 of the rotating shaft structure 30, and the first support 31 is provided with a cam profile. The second support 32 is provided with a follower that cooperates with the cam profile. When the first support 31 rotates relative to the second support 32, the cam profile drives the follower to move the first support 31 relative to the second support 32 along the first direction X, thereby adjusting the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21.

[0121] like Figures 1-6 As shown, in some embodiments, the transmission assembly 34 includes a shaft assembly, a first transmission engagement component 343, and a second transmission engagement component 341. The shaft assembly includes at least one shaft component 342. The first body 10 is capable of driving the shaft component 342 to rotate relative to the third support 33 along the axis 300 of the shaft structure 30 via the first bracket 31. The shaft component 342 includes a engagement section 34201 having a worm gear structure. The first transmission engagement component 343 is disposed on the second support 32 and extends along a first direction X. The second transmission engagement component 341 is rotatably disposed on the third support 33, and the second transmission engagement component 341 engages with the worm gear structure of the engagement section 34201 and the first transmission engagement component 343. Since the second transmission engagement component 341 engages with the worm gear structure and the first transmission engagement component 343, when the rotating shaft component 342 rotates, the worm gear structure drives the second transmission engagement component 341 to rotate. The second transmission engagement component 341 then converts the rotational motion into linear motion along the first direction X through its engagement with the first transmission engagement component 343, thereby pushing the third support 33 to move relative to the second support 32 along the first direction X. Figure 4 As shown, in the first device configuration, the first part 3411 of the second transmission mating component 341 mates with the mating section 34201, and the second part 3412 of the second transmission mating component 341 mates with the first transmission mating component 343. The first part 3411 and the second part 3412 are at different positions along the circumference of the second transmission mating component 341. Figure 6 As shown, in the second device configuration, the third part 3413 of the second transmission engagement component 341 engages with the engagement section 34201, and the fourth part 3414 of the second transmission engagement component 341 engages with the first transmission engagement component 343. The third part 3413 and the fourth part 3414 are at different positions along the circumference of the second transmission engagement component 341. Because the different circumferential positions of the second transmission engagement component 341 engage with the engagement section 34201 and the first transmission engagement component 343 respectively, the power transmission is smoother. Furthermore, the worm gear engagement of the second transmission engagement component 341 has a self-locking characteristic, which helps to stabilize the position of the rotating shaft structure 30 after switching to the target configuration, thus helping to maintain the current configuration.

[0122] The mating section 34201 of the second transmission mating component 341 and the rotating shaft component 342 can be a worm gear structure, that is, the second transmission mating component 341 can be a worm gear, and the mating section 34201 of the rotating shaft component 342 can include a worm gear structure.

[0123] The first transmission engagement component 343 can be a rack structure, which meshes with the teeth of the second transmission engagement component 341 (worm gear) to achieve transmission engagement.

[0124] The first transmission mating component 343 can also be a friction strip with a certain roughness of friction surface, which can drive the first transmission mating component 343 and the second transmission mating component 341 to move in a straight line relative to each other through the rotation of the second transmission mating component 341.

[0125] The mating section 34201 of the rotating shaft component 342 is not limited to a worm gear structure. A helical gear structure can also be provided in the mating section 34201, and correspondingly, the transmission component meshing with the mating section 34201 is a helical gear.

[0126] Alternatively, a combination of worm gear and rack / gear can be used. For example, the mating section 34201 of the rotating shaft component 342 is a worm structure, with the worm wheel meshing with the worm structure. The worm wheel meshes with the first transmission mating component 343 (matting rack) through a coaxially arranged gear. Because this combination of worm gear and rack / gear transmission is used, the self-locking characteristics of the worm gear are retained, while linear motion transmission can be achieved through the rack / gear system.

[0127] Alternatively, bevel gear transmission can be used instead of worm gear transmission. The mating section 34201 of the rotating shaft component 342 can be a first bevel gear, and the transmission assembly 34 can also include a second bevel gear meshing with the first bevel gear and a transmission gear coaxially arranged with the second bevel gear. The transmission gear meshes with the first transmission mating component 343.

[0128] like Figures 7-13As shown, in other embodiments, the transmission assembly 34 may include a shaft assembly, a first transmission engagement component 343, and a gear set 346. The shaft assembly includes at least one shaft component 342. The first body 10 can drive the shaft component 342 to rotate relative to the third support 33 via the first bracket 31. The axis of the shaft component 342, which is directly rotatably connected to the first body 10, is the axis 300 of the shaft structure 30. The shaft component 342 may include a gear engagement section having a gear structure, the axis of which may coincide with the axis of the shaft component 342. The first transmission engagement component 343 is disposed on the second support 32 and extends along a first direction X. The axis of the gear set 346 satisfies a parallel condition (parallel or substantially parallel) with the axis 300 of the shaft structure 30, and the gear set 346 is rotatably disposed on the third support 33. The gear set 346 meshes with the gear engagement section (gear structure) of the shaft component 342 and engages with the first transmission engagement component 343.

[0129] Similarly, the first transmission engagement component 343 can be a rack and pinion structure, which meshes with the gear set 346 to achieve transmission engagement.

[0130] The first transmission mating component 343 can also have a friction strip with a certain roughness. By setting a contact surface that contacts the friction surface on the gear set 346 (such as a friction wheel set at the position corresponding to the fifth part 3461), the rotation of the gear set 346 can drive the first transmission mating component 343 to move linearly relative to the gear set 346.

[0131] During the switching between the first and second device configurations, the fifth part 3461 of the gear set 346 meshes with the gear mating section, and the sixth part 3462 of the gear set 346 meshes with the first transmission mating component 343. The fifth part 3461 and the sixth part 3462 are different parts along the axial direction of the gear set 346. Because the different parts of the gear set 346 along the axial direction mesh with the gear mating section and the first transmission mating component 343 respectively, the gear set 346 can transmit the rotational motion from the rotating shaft component 342 and drive the first transmission mating component 343 to move along the first direction X, realizing the conversion from the rotation of the rotating shaft component 342 to the linear motion of the third support 33.

[0132] The gear set 346 is not limited to a single gear. The gear set 346 can include different gears mounted on the same shaft, each gear having a fifth part 3461 and a sixth part 3462, meaning different teeth of the different gears are respectively located in the fifth part 3461 and the sixth part 3462. These different gears can be half gears (gears with teeth on a portion of their outer circumference) or full gears (gears with teeth on all positions of their outer circumference), etc. The gear set 346 can also be a planetary gear system or a gear reduction group composed of multiple gear sets 346. In a gear set 346 with multiple gears, the transmission ratio can be 1 or other values ​​to adapt to different speed or torque requirements.

[0133] In different equipment configurations, the gear corresponding to the fifth part 3461 meshes with the gear mating section at different circumferential locations, and the gear corresponding to the sixth part 3462 meshes with the first transmission mating component 343 at different circumferential locations.

[0134] In some implementations, such as Figure 6 As shown, the rotating shaft structure 30 may further include a torque assembly 35. The torque assembly 35 includes a first component 351 and a second component 352. The first component 351 rotates synchronously with the rotating shaft component 342. The second component 352 is in frictional engagement with the first component 351 and is also in positional engagement with a third support 33 (e.g., the second component 352 is fixed to the third support 33 or is circumferentially fixed to the third support 33). During the switching between the first device configuration and the second device configuration, the first component 351 and the second component 352 slide against each other to provide torque. Because the first component 351 rotates synchronously with the rotating shaft component 342, and the second component 352 is in positional engagement with the third support 33, the first component 351 slides against the second component 352 during the rotation of the rotating shaft component 342, thereby generating damping torque. This torque allows the first body 10 and the second body 20 to have a good feel during the switching process, and after switching to the target form, the friction helps to maintain the current form. It can be used without setting an additional locking mechanism, or a locking mechanism can be added to further improve the locking effect.

[0135] In this design, the first component 351 can be a rotating friction plate, and the second component 352 can be a fixed friction plate. The torque assembly 35 is not limited to the friction plate structure described above. The torque assembly 35 can also be an elastic damper. The elastic damper includes an elastic element (e.g., a spring or rubber component), one end of which is connected to the rotating shaft component 342, and the other end is connected to the third support 33. When the rotating shaft component 342 rotates, the elastic element undergoes elastic deformation to provide damping torque. The torque assembly 35 can also be a fluid damper or a magnetorheological damper, etc.

[0136] The aforementioned torque can be the resistance torque provided by the rotating shaft structure 30 during rotation, i.e., damping torque or friction torque.

[0137] In some embodiments, the number of rotating shaft components 342 may be one. For example... Figure 3 and Figure 4 As shown, the device may include a first shaft segment (not shown), a second shaft segment (such as mating segment 34201), a third shaft segment 34202, and a fourth shaft segment (not shown) arranged along its axial direction. The first shaft segment is fixedly connected to the first bracket 31, allowing the first body 10 to drive the rotating shaft component 342 to rotate via the first bracket 31. The second shaft segment includes a gear mating segment (i.e., having a worm gear structure or gear structure, etc.) for meshing with a worm wheel (second transmission mating component 341) or a gear set 346 to transmit power. The third shaft segment 34202 is rotatably mated with the third bracket 33 to support the rotation of the rotating shaft component 342 relative to the third bracket 33. The fourth shaft segment may be provided with a torque component 35 for providing damping torque during rotation. Because the shaft segments are arranged sequentially along the axial direction of the rotating shaft component 342 and their functions are clearly distinguished, the rotating shaft component 342 has a compact structure and high integration, which is beneficial for reducing the overall size of the electronic device.

[0138] The rotating shaft component 342 can be a one-piece shaft segment structure. Alternatively, it can be assembled from multiple separate components. For example, the first, second, third, and fourth shaft segments can be independent parts, fixedly connected as a single unit by key connections, pin connections, threaded connections, or welding. A separate structure helps reduce processing difficulty and manufacturing costs.

[0139] In other implementations, such as Figure 9 and Figure 10As shown, the number of rotating shaft components 342 is at least two (including a first rotating shaft component 3421, a second rotating shaft component 3422, a third rotating shaft component 3423, and a fourth rotating shaft component 3424). Adjacent rotating shaft components 342 rotate synchronously via a transmission gear set 346. The number of torque components 35 is at least two (including a first torque set 3501 and a second torque set 3502), and at least two torque components 35 are correspondingly arranged with at least two rotating shaft components 342 (for example, each rotating shaft component 342 is provided with one torque component 35). Because multiple rotating shaft components 342 are used and synchronous rotation is achieved through the transmission gear set 346, the rotating shaft structure 30 can withstand greater torque. Furthermore, since at least two rotating shaft components 342 can be correspondingly provided with torque components 35, each rotating shaft component 342 with a torque component 35 can independently provide damping torque. Therefore, the total torque required by the rotating shaft structure 30 during operation is shared by multiple torque components 35. Under the condition that the material properties (e.g., torsional strength) and total torque requirements of the shaft component 342 remain unchanged, the smaller the torsional load that a single shaft component 342 needs to bear, the smaller the diameter required to meet the strength requirements. Therefore, by setting multiple torque components 35 to share the total torque, the torsional load borne by each shaft component 342 (especially the shaft component 342 directly rotatably connected to the first body 10) is reduced, thus reducing the diameter of a single shaft component 342 while ensuring that the overall torque output remains unchanged. Since the first body 10 is directly rotatably connected to the shaft component 342, the first body 10 needs to provide an installation space at the shaft connection to accommodate the shaft component 342. The dimension of this installation space in the thickness direction is positively correlated with the diameter of the shaft component 342. That is, the larger the diameter of the shaft component 342, the greater the thickness required for the installation space; the smaller the diameter of the shaft component 342, the smaller the thickness required for the installation space. Therefore, by reducing the diameter of the rotating shaft component 342, the thickness requirement of the mounting space of the first body 10 at the rotating shaft connection can be reduced accordingly, thereby facilitating the reduction of the thickness of the first body 10.

[0140] Furthermore, multiple torque components 35 are correspondingly arranged on different shaft parts 342 along the axial direction of the shaft structure 30, so that the damping torque is distributed in the axial direction rather than concentrated in a certain place. This avoids the problem of excessive local stress or excessive local wear caused by torque concentration, which is conducive to extending the service life of the shaft structure 30 and improving the stopping stability of the first body 10 and the second body 20 at any opening and closing angle.

[0141] The two synchronously rotating shaft components 342 described above can rotate at the same angular velocity (i.e., a 1:1 transmission ratio), rotate at a predetermined ratio (i.e., have a constant transmission ratio, such as 1:2 or 2:1), start rotating and stop rotating simultaneously, or have a definite corresponding relationship between their rotation angles. Specific methods of synchronous rotation include meshing transmission gear set 346, transmission via synchronous belt and synchronous pulley, transmission via chain and sprocket, transmission via worm gear, linkage mechanism, or connection via universal coupling, etc.

[0142] like Figures 8-13 As shown, the number of rotating shaft components 342 can be four (first rotating shaft component 3421, second rotating shaft component 3422, third rotating shaft component 3423, and fourth rotating shaft component 3424), with adjacent rotating shaft components 342 connected and rotating synchronously. Torque components 35 can be provided on the rotating shaft components 342 located on both sides (first rotating shaft component 3421 and fourth rotating shaft component 3424). The first rotating shaft component 3421 rotates with the first body 10 along the axis 300 of the rotating shaft structure 30, and the fourth rotating shaft component 3424 includes a gear engagement section that meshes with the fifth part 3461 of the gear set 346.

[0143] In some embodiments, at least two rotating shaft components 342 are present and rotate synchronously. In any two rotating shaft components 342, the first end of one rotating shaft component 342 is opposite to the second end of the other rotating shaft component 342. At least two torque assemblies 35 are present, with pressure members 353 located at the first and second ends, respectively, to apply pressure to the first component 351 and the second component 352. Because the pressure members 353 are located at opposite ends, the pressure applied by the torque assemblies 35 is more balanced axially, avoiding the problem of uneven load caused by unilateral pressure application, thereby improving the stability and consistency of torque output.

[0144] In an embodiment with four rotating shaft components 342, two torque components 35 can be respectively disposed on the first rotating shaft component 3421 and the fourth rotating shaft component 3424. Alternatively, the two torque components 35 can be respectively disposed on the second rotating shaft component 3422 and the third rotating shaft component 3423, or respectively disposed on the second rotating shaft component 3422 and the fourth rotating shaft component 3424, or on the first rotating shaft component 3421 and the third rotating shaft component 3423.

[0145] The number of torque components 35 may be the same as or different from the number of shaft components 342. For example, in an embodiment where the number of shaft components 342 is four, the number of torque components 35 may be one or two, or three or four.

[0146] In some embodiments, the third support 33 may include a sliding connection portion. The second support 32 may include a sliding engagement portion. The sliding connection portion and the sliding engagement portion slide together along the first direction X. During the switching between the first device configuration and the second device configuration, the sliding connection portion and the sliding engagement portion slide relative to each other. Through the engagement of the sliding connection portion and the sliding engagement portion, the movement of the third support 33 relative to the second support 32 along the first direction X is constrained and guided, so that the distance between the axis 300 of the rotating shaft structure 30 and the second functional surface 21 changes according to the requirements, avoiding offset or wobbling.

[0147] The sliding connection can be a slider, and the sliding mating part can be a groove; or the sliding connection can be a groove, and the sliding mating part can be a slider. The fit between the slider and the groove can adopt a dovetail groove structure, a T-groove structure, or a rectangular groove structure, etc., to provide different guiding accuracy and load-bearing capacity.

[0148] The second component 352 (fixed friction plate) may have a sliding part 3521, and the second bracket 32 ​​may have a matching groove. The movement of the sliding part 3521 and the matching groove 3201 along the first direction X is constrained and guided, which facilitates the sliding of the second component 352 and the second bracket 32.

[0149] like Figure 1 and Figure 22 As shown, in some embodiments, the first body 10 may include a first surface 13 opposite to the first functional surface 11. Along a direction perpendicular to the first functional surface 11, the axis 300 of the rotating shaft structure 30 includes a first distance from the first surface 13, and a second distance from the axis 300 to the first functional surface 11, the first distance being greater than the second distance. This arrangement allows the axis 300 of the rotating shaft structure 30 to be closer to the first functional surface 11, which helps to reduce the motion envelope of the first body 10 during device mode switching. Furthermore, the design that the second distance is greater than the first distance prevents interference between the first body 10 and the second body 20 in the second device mode.

[0150] The first body 10 includes a first surface 13 opposite to the first functional surface 11. In the second device configuration, the orientation of the first functional surface 11 and the second functional surface 21 satisfies the same-direction condition, and the first surface 13 and the second functional surface 21 satisfy the contact condition or the clearance fit condition. That is, in the second device configuration, the first body 10 and the second body 20 can achieve a relatively tight stacking fit, which is beneficial to reducing the overall thickness of the electronic device in the unfolded state (second device configuration).

[0151] The "same orientation" condition can be defined as the orientation direction of the first functional surface 11 being approximately the same as that of the second functional surface 21 in the second device configuration. In the second device configuration, when the orientations of the first functional surface 11 and the second functional surface 21 satisfy the same orientation condition, the first body 10 and the second body 20 are in an unfolded or nearly unfolded state. For example, the screen and keyboard of a laptop are opened to approximately 180°, or the two display surfaces of a foldable phone are unfolded to a nearly flat state. It should be noted that the same orientation condition can mean that the orientation direction of the first functional surface 11 is parallel and in the same direction as that of the second functional surface 21, or a certain angular deviation (e.g., a deviation between 0° and 30°) is also permissible.

[0152] The aforementioned contact condition can be a state of direct contact or compression between the first surface 13 of the first body 10 and the second functional surface 21 of the second body 20 in the second device configuration. The clearance fit condition can be a state where, in the second device configuration, there is a small gap between the first surface 13 and the second functional surface 21, the size of which is within the allowable range of machining errors, assembly errors, or design tolerances, or the size of which is sufficient to avoid interference and prevent contact between the two. Meeting the "contact condition" or "clearance fit condition" means that, in the second device configuration, the first surface 13 and the second functional surface 21 are in direct contact or have a small gap. For example, when the first surface 13 and the second functional surface 21 are in direct contact, there is no gap between them; when the first surface 13 and the second functional surface 21 are in clearance fit, the gap size between them is no greater than 0.5 mm. Through the above-described configuration, the first body 10 and the second body 20 can achieve partial contact or a close fit with a small gap in the second device form. This helps reduce the overall thickness of the electronic device in the unfolded state, resulting in a thinner and lighter appearance. It avoids unnecessary increases in thickness caused by the protrusion or suspension of the hinge structure 30 in the unfolded state, thereby improving the product's slim design and user experience. It should be noted that "contact" does not require the first surface 13 and the second functional surface 21 to be in contact across their entire area; rather, at least partial contact is sufficient. Similarly, "gap fit" does not require the gap to be uniform across the entire area; a non-interference gap is sufficient.

[0153] The second functional surface 21 may include a guide groove. During the switching between the first device configuration and the second device configuration, the rotating shaft structure 30 moves along the guide groove. The guide groove provides a predetermined trajectory constraint for the movement of the rotating shaft structure 30, making the movement of the rotating shaft structure 30 relative to the second functional surface 21 smoother and more controllable. The extension direction of the guide groove may be the aforementioned first direction X.

[0154] The number of rotating shaft structures 30 can be at least two, and the axes 300 of at least two rotating shaft structures 30 are located on the same straight line. Using multiple rotating shaft structures 30 with their axes 300 collinearly is beneficial to improving the stability and load-bearing capacity of the rotational connection between the first body 10 and the second body 20.

[0155] like Figure 1 , Figures 14-20 As shown, in other embodiments, the rotating shaft structure 30 may include a first shaft 38 rotatably connected to the first body 10 and a second shaft 39 rotating synchronously with the first shaft 38. The axis 300 of the rotating shaft structure 30 is the axis of the first shaft 38. During the switching of different device configurations, the second shaft 39 can move relative to the second body 20 along a predetermined trajectory, so that the first shaft 38 and the second shaft 39 rotate along the same center line 001, which is located between the first shaft 38 and the second shaft 39. The above arrangement enables the rotating shaft structure 30 to form a rotating structure that rotates along the center line 001, and the first shaft 38 and the second shaft 39 can be arranged radially along this rotating structure. With the above arrangement, the rotation angle of the first body 10 relative to the second body 20 can be the sum of the rotation angle of the rotating shaft structure 30 along the center line 001 and the rotation angle of the first body 10 relative to the first shaft 38. That is, during the switching process, the first body 10 drives the first shaft 38 to rotate around its own axis (i.e., axis 300), and the first shaft 38 drives the second shaft 39 to rotate around the center line 001 relative to the second body 20. The two rotations are superimposed, enabling the first body 10 to achieve a large-angle opening and closing motion relative to the second body 20. In other words, while achieving the same opening and closing angle (e.g., 180°), the required rotation angle range for each shaft (first shaft 38 and second shaft 39) is reduced (less than 180°). As the rotation angle range of each shaft is reduced, the cumulative motion deviation during the rotation process is also reduced, which can improve the stability of the first body 10 during the opening and closing process and reduce the shaking or misalignment caused by the large-angle rotation of the shafts.

[0156] Torque assemblies 35 can be provided on both the first shaft 38 and the second shaft 39. The torque assembly 35 includes a first torque group 3501 on the first shaft 38 and a second torque group 3502 on the second shaft 39. The torque provided by the torque assembly 35 includes the first torque provided by the first torque group 3501 and the second torque provided by the second torque group 3502. That is, the first torque group 3501 is provided on the first shaft 38, and the second torque group 3502 is provided on the second shaft 39. The two torque groups jointly bear the total torque required by the rotating shaft structure 30 during operation.

[0157] Since a first torque group 3501 and a second torque group 3502 are respectively provided on the first shaft 38 and the second shaft 39, the two torque groups jointly bear the total torque required by the rotating shaft structure 30 during operation, thus reducing the torque value required by a single torque group (i.e., the first torque group 3501 or the second torque group 3502). In the design of the torque assembly 35, there is a positive correlation between the torque required by a single torque group and the diameter of the shaft on which it is installed. That is, when a single torque group needs to provide a large torque, the diameter of the shaft on which it is located usually needs to be increased accordingly to withstand the shear stress and torsional stress generated by the torque; conversely, when the torque required by a single torque group decreases, the diameter of the shaft on which it is located can also be decreased accordingly. Based on this, by distributing the total torque to the first torque group 3501 and the second torque group 3502, the torque load borne by each of the first shaft 38 and the second shaft 39 is less than the total torque. Therefore, the diameters of the first shaft 38 and the second shaft 39 can be optimized according to the torque they each bear, without needing to use a larger diameter shaft to bear all the torque. For example, using a single shaft with a diameter of at least 4.5mm, the diameter of the first shaft 38 (and the second shaft 39) can be reduced to 3.5mm or even smaller through the above settings. Since the first body 10 is rotatably connected to the first shaft 38, in the process of slimming down the first body 10 (e.g., the screen part of a laptop), due to the limited internal space, a smaller shaft diameter helps to reduce the installation space requirements of the connection between the first body 10 and the shaft, and reduce the structural thickness requirements of the first body 10 at the shaft connection, thereby facilitating the thinning design of the first body and improving the overall thinness and appearance of the electronic device. Furthermore, the two torque sets can provide a more uniform torque distribution, which is beneficial to improving the force balance and service life of the shaft structure in the width direction.

[0158] in, Figure 14 This is a schematic diagram showing the angle between the first body 10 and the second body 20 changing from 0° to 180°. The first device configuration can be a state where the angle between the first body 10 and the second body 20 is 0°, and the second device configuration can be a state where the angle between the first body 10 and the second body 20 is greater than 0° and less than 180°. Specifically, the first body 10 can be fixedly connected to the first shaft 38 via the first connector 100, and the second body 20 can be movably connected to the second shaft 39 via the second connector 200.

[0159] like Figure 18As shown, the first connecting member 100 and the axis of the first shaft 38 form a first equivalent link L1, and the axis of the first shaft 38 and the axis of the second shaft 39 form a second equivalent link L2. That is, during the change of the included angle between the first body 10 and the second body 20, a rotational fit structure similar to a two-section link is formed between the first body 10 and the second body 20. With the above arrangement, the distance of the axis 300 of the rotating shaft structure 30 relative to the second functional surface 21 can be changed under different equipment configurations.

[0160] like Figure 20 As shown, to improve structural stability, a connecting rod 400 can be provided, with the first shaft 38 and the second shaft 39 rotatably connected to the connecting rod 400 to prevent the first shaft 38 and the second shaft 39 from moving closer or further apart. The centerline 001 can be located on the connecting rod 400.

[0161] The predetermined trajectory can be a pre-defined path followed by the second axis 39 when it moves relative to the second body 20. Since the first axis 38 and the second axis 39 rotate along the same center line 001, the predetermined trajectory can be an arc-shaped trajectory with its center coinciding with the center line 001.

[0162] The center line 001 can be located on the second functional surface 21, on the side facing the second functional surface 21, or on the side facing away from the second functional surface 21.

[0163] The first shaft 38 and the second shaft 39 can be connected by a transmission gear set to achieve synchronous rotation.

[0164] In this embodiment, the first shaft 38 and the second shaft 39 can be gear shafts, that is, the first shaft 38 includes a first gear portion 381, and the second shaft 39 includes a second gear portion 391. The first gear portion 381 and the second gear portion 391 mesh with each other to achieve synchronous transmission between the first shaft 38 and the second shaft 39. The second body 20 (second connecting member 200) can have a mating gear structure 202 that meshes with the second gear portion 391. The mating gear structure 202 can be an arc structure with its center line 001, so that during the rotation of the second shaft 39 driven by the first shaft 38, the second gear portion 391 of the second shaft 39 meshes with the mating gear structure 202 and drives the second shaft 39 to move relative to the second body 20 (second connecting member 200) along a predetermined trajectory.

[0165] Power transmission can be achieved through direct gear-shaft meshing without the need for additional intermediate transmission components, resulting in a compact structure, high transmission efficiency, and reduced overall shaft size. The diameter and number of teeth of the gear sections of the first shaft 38 and the second shaft 39 can be set to be the same or different according to actual needs to achieve different transmission ratios and centerline 001 positions.

[0166] In some embodiments, the diameter of the first gear portion 381 of the first shaft 38 can be substantially the same as the diameter of the second gear portion 391 of the second shaft 39, and the number of teeth of the first gear portion 381 is the same as the number of teeth of the second gear portion 391. Since the diameter and number of teeth of the two gear portions are the same, the transmission ratio between the first shaft 38 and the second shaft 39 is 1:1, that is, they rotate at the same angular velocity. When the diameters of the gear portions of the first shaft 38 and the second shaft 39 are the same, the meshing point of the two gear portions (i.e., the tangent point of the two pitch circles when the two gears mesh) is located at the midpoint between the axis of the first shaft 38 and the axis of the second shaft 39. This meshing point corresponds spatially to the position of the center line 001 of the common rotation of the first shaft 38 and the second shaft 39. Since the diameters of the two gear portions are the same, the center line 001 is located at the midpoint between the axis of the first shaft 38 and the axis of the second shaft 39, and at this time, the center line 001 can be located at the second functional surface 21 (i.e., the center line 001 roughly coincides with the second functional surface). The centerline 001 is located at the second functional surface, so that the motion envelopes of the first body 10 and the second body 20 during the switching process are symmetrically distributed with the second functional surface 21 as the reference, which is beneficial to simplifying the design of the motion trajectory.

[0167] In other embodiments, the diameter of the first gear portion 381 of the first shaft 38 is larger than the diameter of the second gear portion 391 of the second shaft 39, and the number of teeth in the first gear portion 381 is greater than the number of teeth in the second gear portion 391. Because the gear portion of the first shaft 38 has a larger diameter and more teeth, the transmission ratio between the first shaft 38 and the second shaft 39 is less than 1 (i.e., the rotational speed of the first shaft 38 is less than the rotational speed of the second shaft 39, or in other words, the rotational speed of the second shaft 39 is relatively faster). In other words, when the first shaft 38 acts as the driving shaft, the second shaft 39 follows with a higher rotational speed. When the diameter of the gear portion of the first shaft 38 is larger than the diameter of the gear portion of the second shaft 39, the meshing point of the two gear portions is no longer located at the center of the axis of the first shaft 38 and the axis of the second shaft 39, but is closer to the axis of the second shaft 39 (i.e., offset towards the second shaft 39). This is because in gear meshing, the meshing point is located at the tangent point of the two pitch circles; when the radii of the two pitch circles are different, the tangent point will shift towards the gear with the smaller radius. Since the position of the meshing node determines the position of the center line 001 that rotates together with the first shaft 38 and the second shaft 39, in this embodiment, the center line 001 can be located on the opposite side of the second functional surface 21 (i.e., the center line 001 is offset from the second functional surface 21 in a direction away from the first body 10). In this embodiment, the center line 001 can be offset to the opposite side of the second functional surface 21, and the second functional surface 21 needs to have a recessed portion to avoid the first body 10 (e.g., a groove, countersunk platform, or clearance notch is provided on the second functional surface) to provide sufficient clearance space for the movement of the first body 10 during the device mode switching process, and to avoid interference between the first body 10 and the second body 20. Alternatively, the center line 001 can be located on the second functional surface 21 or on the facing side of the second functional surface 21, and the shell of the second body 20 forming the second functional surface 21 needs to have a certain thickness, which, compared to the above embodiment, allows the axis of the second shaft 39 to move towards the second functional surface 21.

[0168] In other embodiments, the diameter of the first gear portion 381 of the first shaft 38 can be smaller than the diameter of the second gear portion 391 of the second shaft 39, and the number of teeth in the first gear portion 381 can be less than the number of teeth in the second gear portion 391. Because the gear portion of the first shaft 38 has a smaller diameter and fewer teeth, the transmission ratio between the first shaft 38 and the second shaft 39 is greater than 1 (i.e., the rotational speed of the first shaft 38 is greater than the rotational speed of the second shaft 39, or in other words, the rotational speed of the second shaft 39 is relatively slower). In other words, when the first shaft 38 acts as the driving shaft, the second shaft 39 follows with a lower rotational speed. When the diameter of the gear portion of the first shaft 38 is smaller than the diameter of the gear portion of the second shaft 39, the meshing point of the two gear portions is no longer located at the exact center of the axis of the first shaft 38 and the axis of the second shaft 39, but rather closer to the axis of the first shaft 38 (i.e., offset towards the first shaft 38). Since the position of the meshing node determines the position of the center line 001 that rotates together with the first shaft 38 and the second shaft 39, in this embodiment, the center line 001 can be located on the side facing the second functional surface 21 (i.e., the center line 001 is offset from the second functional surface 21 towards the first body). In this embodiment, because the center line 001 is offset towards the side facing the second functional surface 21, a certain distance will be formed between the first body 10 and the second body 20 under a specific configuration. By adjusting the ratio of the gear diameters of the first shaft 38 and the second shaft 39, the offset of the center line 001 can be flexibly controlled according to actual needs to adapt to different structural design requirements. Alternatively, the center line 001 can be located on the second functional surface 21.

[0169] The second body 20 has an arc-shaped groove 201 arranged along a predetermined trajectory, and a second shaft 39 is slidably disposed within the arc-shaped groove 201. Through the synchronous rotation of the first shaft 38 and the second shaft 39, and the sliding of the second shaft 39 along the arc-shaped groove 201, the first shaft 38 and the second shaft 39 rotate along the same center line 001. The curvature of the arc-shaped groove 201 (i.e., the angular range of the second shaft 39 sliding within the arc-shaped groove 201) corresponds to the rotational angular range of the first body 10 relative to the second body 20. The curvature of the arc-shaped groove 201 can be adapted to the position of the center line 001 relative to the second functional surface 21.

[0170] In the embodiment where the centerline 001 is located on the second functional surface 21, since the gear diameters and number of teeth of the first shaft 38 and the second shaft 39 are the same (transmission ratio of 1:1), the first shaft 38 and the second shaft 39 are symmetrically arranged on both sides or near the second functional surface. In this case, during the process of the first body switching from the first device form to the second device form relative to the second body, the angle range of the second shaft 39 sliding along the arc groove 201 is basically consistent with the rotation angle range of the first body. For example, the arc of the arc groove 201 can be 90° or approximately 90°. By using an arc groove 201 with a 90° arc, the second shaft 39 can slide smoothly within the arc groove 201, thereby driving the first shaft 38 and the second shaft 39 to rotate along the same centerline 001, realizing the opening and closing movement of the first body relative to the second body within the range of 0° to 90° (or close to 90°).

[0171] In the embodiment where the centerline 001 is located on the side facing the second functional surface 21, the diameter of the gear portion of the first shaft 38 is larger than the diameter of the gear portion of the second shaft 39 (the transmission ratio is less than 1, i.e., the rotational speed of the first shaft 38 is slower than that of the second shaft 39), and the centerline 001 is offset towards the side facing the second functional surface. In this case, there is a certain distance between the first body 10 and the second body 20 in a specific configuration. Because the centerline 001 is offset towards the side facing the second functional surface, the rotation center of the first body 10 is displaced relative to the second functional surface 21, which makes the arc required for the second shaft 39 to slide along the arcuate groove 201 different from the embodiment where the transmission ratio is 1:1. In the embodiment where the centerline 001 is located on the side facing the second functional surface, the arcuate groove 201 can be greater than 90°, for example, 100° to 120°. Since the center line 001 is offset to the side of the facing direction, the second axis 39 needs to slide along the arc groove 201 with a larger curvature to compensate for the change in motion trajectory caused by the offset of the center line 001, so that the first body 10 can smoothly switch from the closed state to the unfolded state, and maintain the preset distance between the first body 10 and the second body 20 in the unfolded state.

[0172] In the embodiment where the centerline 001 is located on the opposite side of the second functional surface 21, the diameter of the gear portion of the first shaft 38 is smaller than the diameter of the gear portion of the second shaft 39 (the transmission ratio is greater than 1, meaning the first shaft 38 rotates faster than the second shaft 39), and the centerline 001 shifts to the opposite side of the second functional surface. In this case, the second functional surface needs to be provided with a recessed portion to avoid the first body. Because the centerline 001 shifts to the opposite side, the rotation center of the first body is displaced in the opposite direction relative to the second functional surface, causing the arc required for the second shaft 39 to slide along the arc groove 201 to differ from both of the above embodiments. In the embodiment where the centerline 001 is located on the opposite side of the second functional surface, the arc of the arc groove 201 can be less than 90°, for example, 60° to 80°. As the center line 001 shifts to the opposite direction, the angle range of the second axis 39 sliding along the arc groove 201 is relatively reduced to adapt to the movement trajectory after the center line 001 shifts, so that the first body 10 can enter the recess of the second functional surface 21 during the switching process, so that the first body 10 and the second body 20 can be in a close fit.

[0173] Alternatively, the position of the centerline 001 relative to the second functional surface 21 can be disregarded, and the curvature of the arc groove 201 can be adjusted based on the size relationship between the diameters of the first gear section 381 and the second gear section 391. The curvature of the arc groove 201 is related to the diameter ratio of the two gear sections. Different diameter ratios will cause changes in the curvature of the trajectory of the second shaft 39 during movement, thus requiring arc grooves 201 with different curvatures to adapt to the trajectory.

[0174] In some embodiments, the diameter of the gear portion of the first shaft 38 can be substantially the same as the diameter of the gear portion of the second shaft 39, and both have the same number of teeth. In this case, the first shaft 38 and the second shaft 39 rotate synchronously with a 1:1 transmission ratio, and the pitch circle radii of the two gear portions are equal. Since the diameters of the two gear portions are the same, the motion trajectory of the second shaft 39 relative to the first shaft 38 is symmetrical. To match this symmetrical motion trajectory, the arcuate groove 201 can be set to 90° or approximately 90°. Using a 90° arcuate groove 201 allows the second shaft 39 to slide smoothly within the arcuate groove 201, thereby driving the first shaft 38 and the second shaft 39 to rotate along the same centerline 001, realizing the opening and closing motion of the first body relative to the second body within the range of 0° to 90° (or close to 90°).

[0175] In other embodiments, the diameter of the gear portion of the first shaft 38 can be larger than the diameter of the gear portion of the second shaft 39, and the number of teeth in the gear portion of the first shaft 38 is greater than the number of teeth in the gear portion of the second shaft 39. In this case, the transmission ratio between the first shaft 38 and the second shaft 39 is less than 1 (i.e., the rotational speed of the first shaft 38 is slower than that of the second shaft 39). Since the diameter of the first gear portion 381 is larger, its pitch circle radius is also larger, which causes the radius of curvature of the motion trajectory of the second shaft 39 relative to the first shaft 38 to change during the rotation following the first shaft 38, and the motion trajectory is no longer symmetrical. In order to adapt to this asymmetrical motion trajectory, the curvature of the arc groove 201 should be increased accordingly. Specifically, when the diameter of the first gear portion 381 is larger than the diameter of the second gear portion 391, the curvature of the arc groove 201 is greater than 90°. For example, when the ratio of the diameter of the first gear portion 381 to the diameter of the second gear portion 391 is 1.2:1 to 1.5:1, the curvature of the arc groove 201 can be 100° to 120°.

[0176] By setting the arc of the arc groove 201 to be greater than 90°, the curvature change of the motion trajectory caused by the large diameter of the first gear part 381 can be effectively compensated. When the second shaft 39 slides along the arc groove 201, the first shaft 38 and the second shaft 39 can rotate along the same center line 001, thereby realizing a smooth switch between the first body and the second body from the closed state to the unfolded state.

[0177] In other embodiments, the diameter of the gear portion of the first shaft 38 may be smaller than the diameter of the gear portion of the second shaft 39, and the number of teeth on the gear portion of the first shaft 38 may be less than the number of teeth on the gear portion of the second shaft 39. In this case, the transmission ratio between the first shaft 38 and the second shaft 39 is greater than 1 (i.e., the first shaft 38 rotates faster than the second shaft 39). Because the diameter of the first gear portion 381 is smaller, its pitch circle radius is also smaller, which causes the radius of curvature of the second shaft 39 relative to the motion trajectory of the first shaft 38 to change in the opposite direction as it follows the rotation of the first shaft 38. To adapt to this motion trajectory, the curvature of the arc groove 201 should be reduced accordingly. In some embodiments, the diameter of the first gear portion 381 is smaller than the diameter of the second gear portion 391, and the curvature of the arc groove 201 is less than 90°. For example, when the ratio of the diameter of the first gear portion 381 to the diameter of the second gear portion 391 is 1:1.2 to 1:1.5, the curvature of the arc groove 201 may be 60° to 80°.

[0178] By setting the arc of the arc groove 201 to less than 90°, it can effectively adapt to the changes in motion trajectory caused by the small diameter of the first gear part 381. When the second shaft 39 slides along the arc groove 201, the first shaft 38 and the second shaft 39 can rotate along the same center line 001, thereby realizing a smooth switching between the first body and the second body.
