Description

Technical Field

[0001] This application relates to the technical field of electronic devices, specifically to a rotating shaft mechanism and an electronic device. Background Technology

[0002] With the continuous development and widespread use of electronic devices, they have become an indispensable part of people's daily lives and work, and people's demands for these devices are also increasing. Taking mobile phones as an example, some phones have incorporated hinge mechanisms, allowing them to switch between flat and folded forms to provide users with different experiences. However, existing hinge mechanisms often occupy a relatively large space inside the phone, limiting further miniaturization. Therefore, miniaturizing the hinge mechanism has become a major focus for industry professionals. Summary of the Invention

[0003] This application provides a rotating shaft mechanism, which includes a fixed component and a rotating component. The fixed component has a mounting groove and a limiting groove on the side wall of the mounting groove. The rotating component includes a rotating member rotatably disposed in the mounting groove and whose rotation trajectory is a first arc, and a limiting member disposed on the rotating member and located in the limiting groove. When the rotating member slides in the mounting groove, the limiting member is driven by the rotating member sliding in the limiting groove and can engage with the groove wall of the limiting groove in the direction in which the rotating member slides out of the mounting groove.

[0004] In another aspect, this application provides an electronic device, which includes: a housing mechanism and the aforementioned rotating shaft mechanism; the housing mechanism has a first housing assembly and a second housing assembly divided along an axis; a fixing assembly is disposed between the first housing assembly and the second housing assembly along the axis; the fixing assembly has the rotating assembly on opposite sides parallel to the axis, and the two rotating assemblies are respectively connected to the first housing assembly and the second housing assembly.

[0005] The rotating shaft mechanism provided in this application allows the rotating component to rotate around the fixed component by slidably placing a rotating part within the mounting groove of the fixed component, with the sliding trajectory of the rotating part being a first arc. Simultaneously, a limiting groove is provided on the side wall of the mounting groove, and the rotating part also has a limiting member protruding from the limiting groove. This limiting member is driven by the sliding of the rotating part within the limiting groove and can engage with the groove wall, thus limiting the sliding of the rotating part. This design, by using a limiting member and a limiting groove to limit the sliding of the rotating part, reduces the amount of contact between the rotating part and the mounting groove, thereby reducing the space occupied by the rotating part and the fixed component after assembly, and achieving a miniaturized design of the rotating shaft mechanism.

[0037] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0038] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the electronic device 10 provided in this application embodiment in a flattened state. Figure 2 yes Figure 1 A schematic diagram of the electronic device 10 in a folded state. Figure 3 yes Figure 1 A schematic diagram of the exploded structure of the electronic device 10.

[0040] The electronic device 10 provided in this application embodiment can be a foldable mobile phone, a foldable tablet computer, a foldable personal digital assistant, or a foldable e-book reader, etc. The following description uses a foldable mobile phone as an example. Figures 1 to 3 As shown, the electronic device 10 may include a display mechanism 100, a housing mechanism 200, and a hinge mechanism 300. The display mechanism 100 is mounted on the housing mechanism 200 and is flexible, allowing it to fold along with the housing mechanism 200. The hinge mechanism 300 is arranged along the axis Y on the housing mechanism 200 and, together with the housing mechanism 200, supports the flattened display mechanism 100. The housing mechanism 200 can also fold along the axis Y via the hinge mechanism 300. In this embodiment, the hinge mechanism 300 has the advantage of occupying little space, which is beneficial for the overall miniaturization design of the electronic device 10.

[0041] The display mechanism 100 is flexible and can fold along the Y-axis along with the housing mechanism 200. The display mechanism 100 may include a transparent cover, a touch panel, and a display panel stacked sequentially. The transparent cover has a smooth surface to facilitate touch operations such as clicking, swiping, and pressing. The transparent cover is made of a flexible material such as colorless polyimide (CPI). The touch panel is positioned between the transparent cover and the display panel to respond to user touch operations and convert these operations into electrical signals that are transmitted to the processor of the electronic device 10, enabling the electronic device 10 to react accordingly. The display panel primarily displays images and can also serve as an interactive interface to instruct the user to perform the aforementioned touch operations on the transparent cover. The display panel can use an OLED (Organic Light-Emitting Diode) screen to achieve image display and folding functionality for the electronic device 10. In this embodiment, the transparent cover, touch panel, and display panel can be bonded together using adhesives such as OCA (Optically Clear Adhesive) and PSA (Pressure Sensitive Adhesive).

[0042] In some embodiments, the display mechanism 100 may not be limited to the stacked structure shown in the foregoing embodiments. That is, the specific structure of the display mechanism 100 can be adaptively selected according to the design requirements of the electronic device 10, as long as the display mechanism 100 is flexible and can be folded along the Y-axis. This embodiment does not limit this. In addition, in some embodiments, when the electronic device 10 is a folding device without display requirements, the design of the display mechanism 100 may be omitted.

[0043] The housing mechanism 200 can be folded along the Y-axis via the pivot mechanism 300, thereby causing the display mechanism 100 to fold along the Y-axis. For example... Figures 1 to 3 As shown, the housing mechanism 200 has a first housing assembly 210 and a second housing assembly 220 divided along the axis Y. The first housing assembly 210 and the second housing assembly 220 are respectively connected to opposite sides of the pivot mechanism 300 parallel to the axis Y. Simultaneously, the first housing assembly 210, the second housing assembly 220, and the pivot mechanism 300 can be flattened together to jointly support the display mechanism 100 placed on the first housing assembly 210, the second housing assembly 220, and the pivot mechanism 300, thereby maintaining the flatness of the display mechanism 100 after flattening. Furthermore, the first housing assembly 210 and the second housing assembly 220 can also be folded along the axis Y via the pivot mechanism 300 to drive the display mechanism 100 to fold along the axis Y, thereby changing the electronic device 10 from a flattened state (…). Figure 1 (As shown) Switch to folded state ( Figure 2 (As shown). Similarly, the first housing assembly 210 and the second housing assembly 220 can also be flattened via the pivot mechanism 300 to switch the electronic device 10 from a folded state back to a flattened state.

[0044] For example, both the first housing assembly 210 and the second housing assembly 220 have a bearing surface 201 facing the display mechanism 100. When the electronic device 10 is in a flattened state, the two bearing surfaces 201 can cooperate with the pivot mechanism 300 to support the flattened display mechanism 100, thereby ensuring the flatness of the display mechanism 100 in the flattened state. For example, the two bearing surfaces 201 can be planes and located in the same plane to improve the consistency of the support provided by the two bearing surfaces 201 to the display mechanism 100. Of course, in some embodiments, the bearing surface 201 may not be a complete plane, and the bearing surface 201 may have some protrusions or depressions. As long as the flatness of the bearing surface 201 can be maintained within a certain range and can support the display mechanism 100 so that the display mechanism 100 has sufficient flatness in the flattened state, this embodiment does not limit this.

[0045] Furthermore, the electronic device 10 can adopt an inward folding design, so that the folded display mechanism 100 is located between the first housing assembly 210 and the second housing assembly 220 to protect the display mechanism 100. Simultaneously, the first housing assembly 210 and the second housing assembly 220 can also be used to install various functional components required by the electronic device 10, such as batteries, microphones, speakers, cameras, and motherboards, etc., and the functional components installed in the first housing assembly 210 and the second housing assembly 220 can be the same or partially the same. For example, batteries can be installed in both the first housing assembly 210 and the second housing assembly 220 to power the functional components installed in the first housing assembly 210 and the second housing assembly 220, respectively.

[0046] Furthermore, the first housing assembly 210 and the second housing assembly 220 can also be symmetrically arranged about axis Y, that is, axis Y can be a symmetrical fold line of the first housing assembly 210 and the second housing assembly 220. Of course, in some embodiments, the first housing assembly 210 and the second housing assembly 220 are not limited to being symmetrically arranged about axis Y, that is, axis Y can also be an asymmetrical fold line of the electronic device 10, as long as the first housing assembly 210 and the second housing assembly 220 can be folded along axis Y. In addition, axis Y can not only be as shown in the figure. Figure 1 and Figure 2 The vertical placement shown allows the electronic device 10 to be folded left and right based on axis Y, and the axis Y can also be placed horizontally, allowing the electronic device 10 to be folded up and down based on axis Y.

[0047] The terms "first," "second," and "third" in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of those features. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or apparatus.

[0048] Please see Figures 4 to 5 , Figure 4 yes Figure 1 A schematic diagram of a partial cross-sectional structure of the electronic device 10 along line V-V. Figure 5 yes Figure 2 A schematic diagram of a partial cross-sectional structure of the electronic device 10 along line VI-VI.

[0049] When the electronic device 10 is in a flattened state, the hinge mechanism 300 can be hidden inside the electronic device 10, and when the electronic device 10 is in a folded state, the hinge mechanism 300 can be exposed outside the electronic device 10. Figures 4 to 5 As shown, when the electronic device 10 is in a flattened state, the side of the first housing assembly 210 facing away from the display mechanism 100 is joined to the side of the second housing assembly 220 facing away from the display mechanism 100, forming a shielding surface 202 for shielding the hinge mechanism 300. The orthographic projection of the hinge mechanism 300 in a direction perpendicular to the shielding surface 202 is located within the shielding surface 202, so that the hinge mechanism 300 can be shielded by the shielding surface 202, allowing the hinge mechanism 300 to be hidden inside the electronic device 10. That is, when the electronic device 10 is in a flattened state, the first housing assembly 210 and the second housing assembly 220 can constitute part of the external structure of the electronic device 10.

[0050] Furthermore, when the electronic device 10 is in a folded state, the first housing assembly 210 and the second housing assembly 220 are joined together to form two parallel sides of the shielding surface 202. The first housing assembly 210 and the second housing assembly 220 can also overlap with opposite sides of the pivot mechanism 300 parallel to the axis Y, and together with the pivot mechanism 300, constitute part of the external structure of the electronic device 10, allowing the pivot mechanism 300 to be exposed outside the electronic device 10. Through the above configuration, the electronic device 10 can form part of its external structure in both flattened and folded states without adding additional structural components, using the cooperation of the first housing assembly 210, the second housing assembly 220, and the pivot mechanism 300, thereby preventing the internal structure of the electronic device 10 from being exposed.

[0051] Furthermore, the first housing assembly 210 may include a first middle frame 211, and the second housing assembly 220 may include a second middle frame 221. For example... Figures 4 to 5 As shown, the first middle frame 211 and the second middle frame 221 are respectively connected to opposite sides of the pivot mechanism 300 parallel to the axis Y. The first middle frame 211, the second middle frame 221, and the pivot mechanism 300 are flattened, and the display mechanism 100 can be placed relatively flat on the first middle frame 211, the second middle frame 221, and the pivot mechanism 300. Simultaneously, the first middle frame 211 and the second middle frame 221 can be folded along the axis Y under the drive of the pivot mechanism 300, and the display mechanism 100 can also be folded along the axis Y along with the first middle frame 211 and the second middle frame 221. In this embodiment, the side of the first middle frame 211 and the second middle frame 221 facing the display mechanism 100 is the aforementioned bearing surface 201.

[0052] Furthermore, when the electronic device 10 is in a flattened state, the first middle frame 211 and the second middle frame 221 are joined at the Y-axis, and the joint can be recessed to form a mounting space 203. The pivot mechanism 300 can be disposed within the mounting space 203 and connected to the first middle frame 211 and the second middle frame 221 respectively. At the same time, the side of the pivot mechanism 300 exposed outside the mounting space 203 can be flush or nearly flush (slightly convex or slightly concave) with the bearing surface 201 of the first middle frame 211 and the second middle frame 221 to jointly support the flattened display mechanism 100. In addition, the side of the first middle frame 211 facing away from the display mechanism 100 is joined with the side of the second middle frame 221 facing away from the display mechanism 100 to form the aforementioned shielding surface 202. The first middle frame 211 and the second middle frame 221 can together constitute part of the external structure of the electronic device 10.

[0053] Furthermore, when the electronic device 10 is in a folded state, the area where the first middle frame 211 and the second middle frame 221 are joined is separated, and the two sides of the shielding surface 202 formed by the joining of the first middle frame 211 and the second middle frame 221 are parallel, allowing the hinge mechanism 300 to be exposed outside the electronic device 10. Simultaneously, the first middle frame 211 and the second middle frame 221 can also overlap with opposite sides of the hinge mechanism 300 parallel to the axis Y, respectively, to avoid the problem of the internal structure of the electronic device 10 being exposed through gaps between the first middle frame 211 and the hinge mechanism 300, and between the second middle frame 221 and the hinge mechanism 300. In addition, the first middle frame 211, the second middle frame 221, and the hinge mechanism 300 together constitute part of the external structure of the electronic device.

[0054] In some embodiments, besides the hinge mechanism 300, the first middle frame 211, and the second middle frame 221 jointly forming part of the external structure of the electronic device 10, a shielding structure (such as leather) can also be provided between the first middle frame 211 and the second middle frame 221 to shield the hinge mechanism 300. With this configuration, regardless of whether the electronic device 10 is in a flattened or folded state, the hinge mechanism 300 can be hidden inside the electronic device 10, while the first middle frame 211, the second middle frame 221, and the shielding structure together form part of the external structure of the electronic device 10, thereby improving the airtightness of the electronic device 10.

[0055] Furthermore, the first housing assembly 210 may further include a first rear cover 212 covering the side of the first middle frame 211 opposite to the display mechanism 100, and the second housing assembly 220 may further include a second rear cover 222 covering the side of the second middle frame 221 opposite to the display mechanism 100. Figures 4 to 5As shown, the first rear cover 212 and the second rear cover 222 can respectively form an accommodating space 204 with the first middle frame 211 and the second middle frame 221 to install various functional devices required by the electronic device 10. Simultaneously, the first rear cover 212 and the second rear cover 222 can also partially cover the first middle frame 211 and the second middle frame 221, thus constituting part of the external structure of the electronic device 10 when it is in a flattened or folded state. Furthermore, in some embodiments, the first rear cover 212 and the second rear cover 222 can also be part of the first middle frame 211 and the second middle frame 221, rather than independent structures disassembled from parts; this embodiment does not limit this.

[0056] In this application embodiment, all directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0057] Please see Figures 6 to 8 , Figure 6 yes Figure 3 Exploded view of the central shaft mechanism 300. Figure 7 yes Figure 1 A schematic diagram of the connection structure between the middle housing mechanism 200 and the partial rotating shaft mechanism 300. Figure 8 yes Figure 2 A schematic diagram of the connection structure between the middle housing mechanism 200 and the partial rotating shaft mechanism 300.

[0058] The pivot mechanism 300 is arranged along the axis Y on the housing mechanism 200, and the housing mechanism 200 can also be folded along the axis Y via the pivot mechanism 300. Figures 6 to 7 As shown, the pivot mechanism 300 may include a fixed component 310 and a rotating component 320. The fixed component 310 is disposed along axis Y between the first housing component 210 and the second housing component 220, and rotating components 320 are provided on opposite sides of the fixed component 310 parallel to axis Y, and are rotatably and slidably connected to the rotating components 320. Simultaneously, the first housing component 210 and the second housing component 220 are also respectively connected to the rotating components 320 on opposite sides of the fixed component 310, allowing the first housing component 210 and the second housing component 220 to be folded or unfolded by rotating the rotating components 320 on the fixed component 310. In this embodiment, the rotating component 320 has the advantage of occupying little space, which helps to reduce the space occupied by the pivot mechanism 300 within the electronic device 10, thereby achieving a miniaturized design of the pivot mechanism 300.

[0059] The fixing component 310 can be used to connect and fix other structural components of the rotating shaft mechanism 300, and the fixing component 310 may include: a base 311. For example... Figures 6 to 7 As shown, the base 311 is arranged along the axis Y between the first housing assembly 210 and the second housing assembly 220. Rotating assemblies 320 are provided on opposite sides of the base 311 parallel to the axis Y, and are rotatably connected to each other. The base 311 may have a mounting groove 3111, which can be an arc-shaped groove and can cooperate with a corresponding part of the rotating assembly 320 to achieve a rotatable connection between the rotating assembly 320 and the base 311. That is, the part of the rotating assembly 320 corresponding to the mounting groove 3111 can be located within the mounting groove 3111 and can slide within it, making the sliding trajectory of the rotating assembly 320 an arc, thus achieving a rotatable connection between the rotating assembly 320 and the base 311.

[0060] With the above configuration, the rotating component 320 can be rotatably connected to the base 311 via the virtual axis formed by the mounting groove 3111. This helps to reduce the stacking height of the rotating component 320 and the base 311 in the thickness direction Z, thereby achieving miniaturization of the rotating shaft mechanism 300 in the thickness direction Z, and reducing the limitations imposed by the rotating shaft mechanism 300 on the thinning of the electronic device 10. In this embodiment, the aforementioned thickness direction Z refers to the direction in which the first housing component 210 and the second housing component 220 approach or move away from the display mechanism 100 in the flattened state, and the thickness direction Z can also be perpendicular to the aforementioned bearing surface 201 and the extension direction of the axis Y.

[0061] Furthermore, the number of bases 311 can be multiple, and the multiple bases 311 can be arranged at intervals along the axis Y between the first housing assembly 210 and the second housing assembly 220. The spacing between any two adjacent bases 311 can be the same or different, and the space between adjacent bases 311 can be used for wiring (such as flexible circuit boards) to achieve electrical connection between functional devices respectively mounted on the first housing assembly 210 and the second housing assembly 220. For example, the number of bases 311 can be three, and the three bases 311 can be arranged along the axis Y at the top, middle, and bottom of the first housing assembly 210 and the second housing assembly 220, respectively, and the spacing between any two adjacent bases 311 is the same. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0062] In some embodiments, the number of bases 311 may not be limited to three, and may also be two, four, five or more. That is, the number of bases 311 can be adaptively selected according to the design requirements of the electronic device 10. It is sufficient that multiple bases 311 are arranged at intervals along the axis Y between the first housing assembly 210 and the second housing assembly 220. This embodiment does not limit this.

[0063] Furthermore, each base 311 may be provided with a rotating component 320 on opposite sides parallel to the axis Y, so that the fixed component 310 may have the same number of rotating components 320 as the base 311 on the same side parallel to the axis Y. Simultaneously, since the multiple bases 311 are spaced apart, the multiple rotating components 320 may also be spaced apart on the same side of the fixed component 310. For example, when there are three bases 311, the fixed component 310 may have three spaced-apart rotating components 320 on one side parallel to the axis Y, and three spaced-apart rotating components 320 on the opposite side parallel to the axis Y, so that both the first housing component 210 and the second housing component 220 can be rotatably connected to the fixed component 310 through the three rotating components 320, thereby improving the stability of the first housing component 210 and the second housing component 220 when folded or flattened. Furthermore, the two rotating components 320 located on opposite sides of the base 311 parallel to the axis Y can also be symmetrically arranged about the axis Y to improve the consistency of the rotation of the two rotating components 320 relative to the base 311.

[0064] In some embodiments, the rotation components 320 may not be limited to one on each opposite side of the base 311 parallel to the axis Y. That is, two spaced-apart rotation components 320 may be provided on one side of the base 311 parallel to the axis Y, and two, three or more spaced-apart rotation components 320 may be provided on the other opposite side. It is sufficient that each opposite side of the base 311 parallel to the axis Y is provided with rotation components 320, and this embodiment does not limit this. In addition, the rotation components 320 located on the opposite sides of the base 311 parallel to the axis Y can be arranged symmetrically about the axis Y, or asymmetrically on the opposite sides of the base 311 parallel to the axis Y, and this embodiment does not limit this either.

[0065] In some embodiments, multiple bases 311 may be connected to form a single, longer base 311 (equivalent to having only one base 311). Since there is no gap space formed by multiple bases 311 spaced along the Y-axis, the longer base 311 can also form vias for wiring to achieve electrical connection between functional devices respectively mounted on the first housing assembly 210 and the second housing assembly 220. Simultaneously, at least one rotating component 320 may be provided on each opposite side of the longer base 311 parallel to the Y-axis, and the number of rotating components 320 on opposite sides of the longer base 311 parallel to the Y-axis may be the same or different, and they may be symmetrically or asymmetrically arranged about the Y-axis.

[0066] Furthermore, the fixing component 310 may also include a rotating shaft 312. For example... Figures 7 to 8 As shown, the rotating shaft 312 is mounted on the base 311, and the rotation direction X of the rotating shaft 312 is parallel to the extension direction of the axis Y. The corresponding structural component in the rotating assembly 320 can be sleeved on the rotating shaft 312 and rotatably connected to it. Simultaneously, the corresponding structural component in the rotating assembly 320 is also slidably connected to the rotating shaft 312, with the sliding direction coinciding with the rotation direction X, allowing the rotating assembly 320 to rotate and slide on the fixed assembly 310. That is, in addition to enabling the rotatable connection between the rotating assembly 320 and the base 311, the rotating shaft 312 can also enable the slidable connection between the rotating assembly 320 and the base 311, and can guide the sliding of the rotating assembly 320. In this embodiment, the rotating shaft 312 is preferably fixed to the base 311, which helps improve the structural stability of the rotating shaft mechanism 300.

[0067] Furthermore, since a rotating assembly 320 is provided on each of the opposite sides of the base 311 parallel to the axis Y, two rotating shafts 312 can also be provided on the base 311. The corresponding structural components of the two rotating assemblies 320 can be respectively fitted onto the two rotating shafts 312 to achieve rotation and sliding on the base 311. At the same time, the two rotating shafts 312 can also be symmetrically arranged on the base 311 about the axis Y to improve the consistency of rotation of the rotating assemblies 320 on opposite sides of the base 311. When there are multiple bases 311, the two rotating shafts 312 can be designed to be relatively long and pass through multiple bases 311 to cooperate with the rotating assemblies 320 on multiple bases 311, thereby simplifying the structure of the rotating shaft mechanism 300. Alternatively, the two rotating shafts 312 can be broken into multiple short rotating shafts, the same number as the rotating assembly 320. These short rotating shafts can be arranged in pairs on multiple bases 311 to cooperate with the rotating assembly 320 on the bases 311, thereby reducing the weight of the rotating shaft mechanism 300. Similarly, when the base 311 is the aforementioned longer base 311, the two rotating shafts 312 can be designed to be longer and arranged on the base 311, or they can be broken into multiple short rotating shafts and arranged on the base 311. This embodiment does not limit this.

[0068] Furthermore, the fixing component 310 may also include a shielding member 313. For example... Figures 7 to 8 As shown, the shielding member 313 is disposed on one side of the base 311 and connected to the base 311 to fix the base 311. Simultaneously, the edge of the shielding member 313 can protrude in the direction away from the base 311, allowing the shielding member 313 to enclose a shielding space to accommodate the base 311. When the electronic device 10 is in a flattened state, the first housing assembly 210 and the second housing assembly 220 can be joined together on the side of the shielding member 313 away from the base 311 to form a shielding surface 202, which shields the shielding member 313. Meanwhile, when the electronic device 10 is in a folded state, the first housing assembly 210 and the second housing assembly 220 are spliced ​​together to form two parallel sides of the shielding surface 202. The first housing assembly 210 and the second housing assembly 220 also overlap with the shielding member 313 on opposite sides (protruding edges) parallel to the axis Y, and together with the shielding member 313, they constitute part of the external structure of the electronic device 10, so as to use the shielding member 313 to shield the internal structure of the electronic device 10.

[0069] In some embodiments, the shielding member 313 may also be part of the base 311, rather than a structure independent of the base 311. For example, when there are multiple bases 311, the multiple bases 311 may be spaced apart along the Y-axis within the shielding space enclosed by the shielding member 313, so as to shield and fix the multiple bases 311 using the shielding member 313. At the same time, the multiple bases 311 and the shielding member 313 may be integrally manufactured by processes such as in-mold injection molding, so that the multiple bases 311 and the shielding member 313 can be formed as one unit. When the multiple bases 311 and the shielding member 313 are formed as one unit, the multiple bases 311 and the shielding member 313 may also together constitute the longer base 311 in the aforementioned embodiments.

[0070] The rotating component 320 is rotatably and slidably connected to the fixed component 310, and the first housing component 210 and the second housing component 220 can be folded or flattened by rotating and sliding the rotating component 320 on the fixed component 310. The following explanation uses only the rotating component 320 connecting the first housing component 210 and the fixed component 310 as an example. Figures 7 to 8 As shown, the rotating assembly 320 may include: a rotating member 321, a rotating member 322, a fixed bracket 323, and a connecting bracket 324. The rotating member 321 is located on the side of the fixed assembly 310 parallel to the Y-axis and is rotatably and slidably connected to the fixed assembly 310. The rotating member 321 is also rotatably connected to the connecting bracket 324. The rotating members 322 and 321 are located on the same side of the fixed assembly 310 and are rotatably connected to it. The rotation axis of the rotating member 322 is parallel to the rotation axis of the rotating member 321. The fixed bracket 323 is connected to the rotating member 322 and to the first housing assembly 210. The fixed bracket 323 is also rotatably connected to the connecting bracket 324. It is understood that the connection method between the second housing assembly 220 and the rotating assembly 320 is the same as that between the first housing assembly 210 and the rotating assembly 320, and will not be described in detail here.

[0071] Furthermore, when the user folds the first housing assembly 210 and the second housing assembly 220, the first housing assembly 210 and the second housing assembly 220 can drive the rotating member 322 to rotate around the fixed assembly 310 via the fixed bracket 323, thereby realizing the rotational folding of the first housing assembly 210 and the second housing assembly 220. During this process, that is, when the fixed bracket 323 rotates around the fixed assembly 310 with the rotating member 322, the connecting bracket 324 can rotate with the fixed bracket 323, thereby driving the rotating member 321 to rotate around the fixed assembly 310. Simultaneously, since the rotation axes of the rotating member 321 and the rotating member 322 are parallel (their rotation trajectories are inconsistent), the connecting bracket 324 can also rotate relative to the fixed bracket 323 and the rotating member 321, thereby driving the rotating member 321 to slide along its rotation axis on the fixed assembly 310. In other words, the connecting bracket 324 can be linked with the fixed bracket 323 to drive the rotating member 321 to rotate and slide on the fixed assembly 310. With this configuration, the rotating component 321 can be linked with the rotating component 322 and the fixed support 323 via the connecting bracket 324 to achieve the function corresponding to the rotating shaft mechanism 300.

[0072] Please combine Figures 7 to 8 See 9 to Figure 12 , Figure 9 These are partial structural schematic diagrams of the rotating shaft mechanism 300 in some embodiments. Figure 10 yes Figure 7 A schematic diagram of the structure of the rotating component 321. Figure 11 yes Figure 7 A schematic diagram of the structure of the fixed bracket 323.

[0073] In some embodiments, in order to achieve the linkage between the rotating member 321 and the rotating member 322, the fixed bracket 323 needs to be connected to the rotating member 321 and the rotating member 322 respectively. Figure 9 (As shown). Simultaneously, since the rotation axes of rotating member 321 and rotating member 322 are parallel, the fixed bracket 323 also needs to be slidably connected to rotating member 321 so that it can slide relative to rotating member 321 when driving rotating member 321 to rotate around fixed assembly 310, thereby avoiding restriction on the rotation of rotating member 321. However, limited by the slidable connection between fixed bracket 323 and rotating member 321, the rotating shaft mechanism 300 not only needs to occupy more space in the width direction W to allow sliding clearance between fixed bracket 323 and rotating member 321, but also needs to occupy more space in the thickness direction Z to form the sliding structure 303 required for the slidable connection between fixed bracket 323 and rotating member 321. Figure 9(As shown). It is evident that the above solution simultaneously increases the space occupied by the pivot mechanism 300 in both the width direction W and the thickness direction Z. This not only limits the miniaturization of the electronic device 10 but also reduces the usable space inside the electronic device 10. The aforementioned width direction W refers to the direction in which the first housing assembly 210 and the second housing assembly 220 move away from or closer to each other in their flattened state, and is perpendicular to the thickness direction Z and the extension direction of the axis Y, respectively.

[0074] To address the aforementioned issues, this embodiment provides a connecting bracket 324 that is rotatably connected to both the fixed bracket 323 and the rotating component 321. Furthermore, the connecting bracket 324 is linked with the fixed bracket 323 to drive the rotating component 321 to rotate and slide on the fixed assembly 310. Compared to the aforementioned scheme where the fixed bracket 323 and rotating component 321 are directly slidably connected, the space required by the connecting bracket 324 in this embodiment is significantly less than the space required by the sliding connection between the fixed bracket 323 and rotating component 321. This helps reduce the space occupied by the rotating assembly 320 within the electronic device 10, thereby achieving a miniaturized design of the rotating shaft mechanism 300.

[0075] The rotating component 321 is rotatably connected to both the connecting bracket 324 and the fixing component 310, and is also slidably connected to the fixing component 310, and can rotate and slide relative to the fixing component 310 under the drive of the connecting bracket 324. Figure 7 and Figure 8 As shown, the rotating member 321 can be sleeved on the rotating shaft 312 and rotatably connected to the rotating shaft 312, allowing the rotating member 321 to rotate about the rotating shaft direction X around the base 311. Simultaneously, the rotating member 321 is also slidably connected to the rotating shaft 312, allowing the rotating member 321 to slide on the base 311 about the rotating shaft direction X. With this configuration, the rotating member 321 can achieve rotation and sliding on the fixed component 310 via the rotating shaft 312.

[0076] In some embodiments, besides being connected to the base 311 via the pivot 312, the rotating member 321 can also be connected to the base 311 via a virtual axis. That is, the base 311 may also have a first sliding groove (arc-shaped groove) similar to the mounting groove 3111, and the virtual axis formed by the mounting groove 3111 and the virtual axis formed by the first sliding groove are parallel. A portion of the rotating member 321 can be located within the first sliding groove and can slide within it, allowing the rotating member 321 to rotate around the base 311 using the virtual axis formed by the first sliding groove, thus achieving a rotatable connection between the rotating member 321 and the base 311. Simultaneously, the width of the first sliding groove in the extension direction of the axis Y can be greater than the width of the rotating member 321 in the extension direction of the axis Y, allowing the rotating member 321 to also slide within the first sliding groove in a direction parallel to the axis Y, thus achieving a sliding connection between the rotating member 321 and the base 311.

[0077] Furthermore, the rotating component 321 is also provided with a first clearance groove 3211, and the portion of the connecting bracket 324 that is rotatably connected to the rotating component 321 is located within the first clearance groove 3211. For example... Figures 7 to 8 as well as Figure 10 As shown, the rotating member 321 has a first side 3212, which is the side of the rotating member 321 located in its own rotation direction. The rotating member 321 has a first clearance groove 3211 on the first side 3212, and the first clearance groove 3211 also penetrates the side of the rotating member 321 near the fixed bracket 323 and the side of the rotating member 321 away from the fixed assembly 310 (rotating shaft 312). The connecting bracket 324 can be inserted into the first clearance groove 3211 from the first side 3212 or the side of the rotating member 321 near the fixed bracket 323, and protrude from the slot formed by the first clearance groove 3211 on the side of the rotating member 321 near the fixed bracket 323, so as to be rotatably connected with the fixed bracket 323. Meanwhile, the first clearance groove 3211 forms a slot on the side of the rotating member 321 close to the fixed bracket 323, and the first clearance groove 3211 forms a slot on the side of the rotating member 321 away from the rotating shaft 312, which can also avoid the rotation of the connecting bracket 324.

[0078] With the above configuration, the rotating member 321 can accommodate the connecting bracket 324 using the first clearance groove 3211, thereby reducing the stacking height of the rotating member 321 and the connecting bracket 324 in the thickness direction Z. This is beneficial for the miniaturization design of the rotating shaft mechanism 300. In this embodiment, the first clearance groove 3211 is provided at the end of the rotating member 321 away from the rotating shaft 312, and the first side 3212 can also be the side of the rotating member 321 closer to the display mechanism 100. Of course, in some embodiments, the location of the first clearance groove 3211 can also be adjusted according to design requirements, and is not limited to the end of the rotating member 321 away from the rotating shaft 312 and the first side 3212. For example, the first clearance groove 3211 can also be provided on the side of the rotating member 321 away from the first side 3212, and located between the two ends of the rotating member 321 that are closer to and farther from the rotating shaft 312. This embodiment does not limit this.

[0079] In some embodiments, the first clearance groove 3211 may also be formed on the side of the rotating member 321 near the fixed bracket 323, and the connecting bracket 324 may be inserted into the first clearance groove 3211 from the side of the rotating member 321 near the fixed bracket 323 to improve the stability of the rotational connection between the connecting bracket 324 and the rotating member 321. Simultaneously, the first clearance groove 3211 may also penetrate the side of the rotating member 321 away from the rotating shaft 312 to form a corresponding slot to allow the rotation of the connecting bracket 324 to pass through. Of course, the first clearance groove 3211 may not penetrate the side of the rotating member 321 away from the rotating shaft 312; it is sufficient that the slot formed by the first clearance groove 3211 on the side of the rotating member 321 near the fixed bracket 323 can allow the connecting bracket 324 to pass through. This embodiment does not limit this. Furthermore, in some embodiments, the design of the first clearance groove 3211 may be omitted, and the connecting bracket 324 may be directly provided on the first side 3212 and rotatably connected to the rotating member 321.

[0080] The rotating member 322 is rotatably connected to the fixed assembly 310 and is capable of rotating around the fixed assembly 310 between a first position and a second position. For example... Figures 7 to 8As shown, rotating member 322 and rotating member 321 are located on the same side of base 311, and are positioned opposite and spaced apart from rotating member 321 in a direction parallel to axis Y. A portion of rotating member 322 is located within mounting groove 3111 and can slide within it, allowing rotating member 322 to be rotatably connected to base 311 via a virtual axis formed by mounting groove 3111, enabling rotation between a first position and a second position. When rotating member 322 is in the first position, the first housing assembly 210 and the second housing assembly 220 can be flattened (electronic device 10 is in a flattened state). When rotating member 322 is in the second position, the first housing assembly 210 and the second housing assembly 220 can be folded (electronic device 10 is in a folded state). When rotating member 322 rotates from the first position to the second position, rotating member 321 slides towards rotating member 322 under the influence of connecting bracket 324. When the rotating member 322 rotates from the second position to the first position, the rotating member 321 slides away from the rotating member 322 under the drive of the connecting bracket 324. In this embodiment, the direction in which the rotating member 321 approaches or moves away from the rotating member 322 is the aforementioned rotation axis direction X.

[0081] In some embodiments, in addition to being rotatably connected to the base 311 via the mounting groove 3111, the rotating member 322 can also be rotatably connected to the base 311 via a solid shaft such as the rotating shaft 312. It is only necessary that the rotation axis directions of the rotating member 322 and the rotating member 321 are parallel. This embodiment does not limit this.

[0082] The fixed bracket 323 is connected to the rotating member 322 and the first housing assembly 210 respectively, and is rotatably connected to the connecting bracket 324. For example... Figures 7 to 8 As shown, the fixed bracket 323 is connected to the portion of the rotating member 322 away from the base 311, and is positioned opposite and spaced apart from the rotating member 321 in the direction parallel to the Y-axis, so that the connecting bracket 324 can be rotatably connected to the fixed bracket 323 and the rotating member 321 respectively. Simultaneously, the fixed bracket 323 is also connected to the first housing assembly 210 (first middle frame 211), and can rotate the rotating member 322 around the base 311 between a first position and a second position, driven by the first housing assembly 210. It can be understood that the first housing assembly 210 and the second housing assembly 220 can be connected to the fixed bracket 323 of the rotating assembly 320 located on opposite sides of the base 311, allowing the first housing assembly 210 and the second housing assembly 220 to fold along the Y-axis.

[0083] Furthermore, the fixed bracket 323 is also movably connected to the rotating member 322, allowing the first housing assembly 210 to move relative to the rotating member 322 via the fixed bracket 323. Figure 7 and Figure 11As shown, the fixed bracket 323 has a second sliding groove 3231, which is an arc-shaped groove. The rotating member 322 has a sliding part 3221 located within the second sliding groove 3231, and this sliding part 3221 can slide within the second sliding groove 3231 to rotatably connect with the fixed bracket 323 using the virtual axis formed by the second sliding groove 3231 (parallel to the rotation axis direction X). When the fixed bracket 323 rotates around the base 311 with the rotating member 322, the fixed bracket 323 can also rotate relative to the rotating member 322 under the drive of the first housing assembly 210 to adjust the position of the first housing assembly 210. With this configuration, the first housing assembly 210 and the second housing assembly 220 can rotate relative to the rotating member 322 to adjust their positions during folding, avoiding the limitation of the rotation angle of the rotating member 322 on the first housing assembly 210 and the second housing assembly 220, thereby ensuring that the first housing assembly 210 and the second housing assembly 220 can be joined together without gaps.

[0084] In some embodiments, in addition to being rotatably connected to the rotating member 322 via the second slide groove 3231 (virtual axis), the fixed bracket 323 can also be rotatably connected to the rotating member 322 via a physical axis parallel to the rotation axis direction X. As long as the fixed bracket 323 can rotate relative to the rotating member 322 to adjust its own position under the drive of the first housing assembly 210, so as to ensure that the first housing assembly 210 and the second housing assembly 220 can be merged without gaps, this embodiment does not limit this.

[0085] In some embodiments, the connection between the fixed bracket 323 and the rotating member 322 may not be limited to a rotatable connection. For example, the second groove 3231 may be a straight groove, while the sliding part 3221 may still be disposed within the second groove 3231 and slide within it (the sliding direction intersects the thickness direction Z and the width direction W respectively), thereby achieving a sliding connection between the fixed bracket 323 and the rotating member 322. Similar to the embodiment with a rotatable connection described above, the fixed bracket 323 can still slide relative to the rotating member 322 under the drive of the first housing assembly 210, allowing the first housing assembly 210 and the second housing assembly 220 to adjust their positions relative to the rotating member 322, ensuring that the first housing assembly 210 and the second housing assembly 220 can be folded together without gaps during folding.

[0086] Furthermore, the fixed bracket 323 also has a second clearance groove 3232, and the portion of the connecting bracket 324 that is rotatably connected to the fixed bracket 323 is located within the second clearance groove 3232. For example... Figures 7 to 8 as well as Figure 11As shown, the fixed bracket 323 has a second side 3233, which is the side of the fixed bracket 323 located in the rotation direction of the rotating member 322. A second clearance groove 3232 is formed on the second side 3233 of the fixed bracket 323, and the second clearance groove 3232 also penetrates the side of the fixed bracket 323 near the rotating member 321 and the side of the fixed bracket 323 away from the fixed assembly 310 (base 311). The connecting bracket 324 can be inserted into the second clearance groove 3232 from the second side 3233 or the side of the fixed bracket 323 near the rotating member 321, and protrude from the slot formed by the second clearance groove 3232 on the side of the fixed bracket 323 near the rotating member 321, so as to be rotatably connected to the rotating member 321. Meanwhile, the second clearance groove 3232 formed on the side of the fixed bracket 323 near the rotating member 321, and the second clearance groove 3232 formed on the side of the fixed bracket 323 away from the base 311, can also avoid the rotation of the connecting bracket 324.

[0087] With the above configuration, the fixed bracket 323 can accommodate the connecting bracket 324 using the second clearance groove 3232, thereby reducing the stacking height of the fixed bracket 323 and the connecting bracket 324 in the thickness direction Z. This is beneficial for the miniaturization design of the rotating shaft mechanism 300. In this embodiment, the second clearance groove 3232 is formed in a portion of the fixed bracket 323 near the rotating member 321, and the second side 3233 can be the side of the fixed bracket 323 near the display mechanism 100. Of course, in some embodiments, the position of the second clearance groove 3232 can also be adjusted according to design requirements, and is not limited to the portion of the fixed bracket 323 near the rotating member 321 and the second side 3233. For example, the second clearance groove 3232 can also be formed on the side of the fixed bracket 323 away from the second side 3233, and located in a portion of the fixed bracket 323 slightly away from the rotating member 321. This embodiment does not limit this.

[0088] In some embodiments, the second clearance groove 3232 may also be formed on the side of the fixed bracket 323 near the rotating member 321, and the connecting bracket 324 may be inserted into the second clearance groove 3232 from the side of the fixed bracket 323 near the rotating member 321 to improve the stability of the rotational connection between the connecting bracket 324 and the rotating member 321. Simultaneously, the second clearance groove 3232 may also penetrate the side of the fixed bracket 323 away from the base 311 to form a corresponding slot to allow for the rotation of the connecting bracket 324. Of course, the second clearance groove 3232 may not penetrate the side of the fixed bracket 323 away from the base 311; it is sufficient that the slot formed by the second clearance groove 3232 on the side of the fixed bracket 323 near the rotating member 321 can allow for the connection bracket 324 to pass through. This embodiment does not limit this. Furthermore, in some embodiments, the design of the second clearance groove 3232 may be omitted, and the connecting bracket 324 may be directly provided on the second side 3233 and rotatably connected to the fixed bracket 323.

[0089] Please see Figures 12 to 15 , Figure 12 yes Figure 7 A schematic diagram of the connection structure between the middle fixing component 310 and the rotating component 320. Figure 13 yes Figure 8 A schematic diagram of the connection structure between the middle fixing component 310 and the rotating component 320. Figure 14 yes Figure 1 A schematic diagram of the connection structure of the middle rotating shaft mechanism 300. Figure 15 yes Figure 2 A schematic diagram of the connection structure of the middle rotating shaft mechanism 300.

[0090] The connecting bracket 324 is rotatably connected to both the rotating component 321 and the fixed bracket 323, and can be linked with the fixed bracket 323 to drive the rotating component 321 to rotate and slide on the rotating shaft 312. Figures 12 to 13 As shown, the connecting bracket 324 can be elongated, with one end of the connecting bracket 324 located in the first clearance groove 3211 and rotatably connected to the rotating member 321, while the other end of the connecting bracket 324 is located in the second clearance groove 3232 and rotatably connected to the fixed bracket 323. Simultaneously, the two opposite ends of the connecting bracket 324 are parallel to the rotation axis directions on the rotating member 321 and the fixed bracket 323, and perpendicular to the plane containing the first side 3211 and the second side 3233. With this configuration, when the fixed bracket 323 rotates around the base 311 with the rotating member 322, the connecting bracket 324 can rotate around the base 311 with the fixed bracket 323, thereby driving the rotating member 321 to rotate on the rotation axis 312. The connecting bracket 324 will also rotate synchronously relative to the fixed bracket 323 and the rotating member 321, thereby driving the rotating member 321 to slide on the rotation axis 312 towards or away from the rotating member 322.

[0091] In some embodiments, the connecting bracket 324 may be elongated, having two opposite ends along its length, or it may be in other shapes, not limited to elongated. That is, the shape of the connecting bracket 324 can be selected according to design requirements, as long as the connecting bracket 324 can be rotatably connected to the rotating member 321 and the fixed bracket 323 respectively. This embodiment does not limit this.

[0092] Furthermore, to achieve a rotatable connection between the connecting bracket 324 and the rotating member 321 and the fixed bracket 323, the rotating assembly 320 may further include: a first pin 325 and a second pin 326. For example... Figures 12 to 13 As shown, a first pin 325 passes through one end of the connecting bracket 324 and the rotating member 321, and is fastened to one of the connecting bracket 324 and the rotating member 321, allowing the connecting bracket 324 and the rotating member 321 to be rotatably connected via the first pin 325. A second pin 326 passes through the other opposite end of the connecting bracket 324 and the fixed bracket 323, and is fastened to one of the connecting bracket 324 and the fixed bracket 323, allowing the connecting bracket 324 and the fixed bracket 323 to be rotatably connected via the second pin 326. The axial directions of the first pin 325 and the second pin 326 are parallel and perpendicular to the plane containing the first side 3211 and the second side 3233.

[0093] In some embodiments, the first pin 325 and the second pin 326 may also be part of the connecting bracket 324 and integrally manufactured with the connecting bracket 324 by a process such as in-mold injection molding, rather than being structural components independent of the connecting bracket 324. That is, the first pin 325 and the second pin 326 may be fastened to the connecting bracket 324 and be rotatable relative to the rotating member 321 and the fixed bracket 323.

[0094] In some embodiments, in addition to being rotatably connected to the rotating member 321 and the fixed bracket 323 respectively via the first pin 325 and the second pin 326, the connecting bracket 324 can also be rotatably connected to the rotating member 321 and the fixed bracket 323 by forming a virtual axis using arc grooves on the rotating member 321 and the fixed bracket 323 respectively.

[0095] In some embodiments, the connecting bracket 324 can also be rolledly connected to the rotating member 321 and the fixed bracket 323 respectively, so that the connecting bracket 324 can both rotate relative to the rotating member 321 and the fixed bracket 323 and slide relative to the rotating member 321 and the fixed bracket 323 to meet different design requirements. It is only necessary that the connecting bracket 324 can rotate relative to the rotating member 321 and the fixed bracket 323 and can drive the rotating member 321 to rotate and slide on the rotating shaft 312.

[0096] Furthermore, the connecting bracket 324, the rotating component 321, and the rotating shaft 312 can together form a triangular structure, enabling the rotating shaft mechanism 300 to have strong stability and enhancing its impact resistance when the electronic device 10 is dropped. Figures 12 to 13 As shown, the line connecting the rotation axes of the connecting bracket 324 on the rotating member 321 and the fixed bracket 323 can be the axis L of the connecting bracket 324. When the rotating member 322 is in the first or second position, that is, when the electronic device 10 is in a folded or flattened state, the extension direction of the axis L intersects the orthographic projection of the rotation axis direction X of the rotating member 321 in the same plane. Simultaneously, the extension directions of the axis L, the rotation axis direction X, and the lines connecting the rotating member 321 to the two ends connected to the connecting bracket 324 and the rotating shaft 312 (hereinafter referred to as line segment M) can intersect in the same plane to form a triangle. With this configuration, the connecting bracket 324, the rotating member 321, and the rotating shaft 312 can collectively form a triangular structure, giving the rotating shaft mechanism 300 strong stability and enhancing its impact resistance when the electronic device 10 is dropped.

[0097] In some embodiments, the angle formed by the intersection of the extension direction of the axis line L and the orthographic projection of the rotation axis direction X in the same plane can be less than or equal to 45°, specifically 45°, 30°, or 15°. The smaller the angle, the narrower the width occupied by the connecting bracket 324 in the width direction W, thereby reducing the space occupied by the rotating component 320 in the width direction W. Simultaneously, the extension direction of the line segment M is perpendicular to the orthographic projection of the rotation axis direction X in the same plane, allowing the orthographic projections of the extension direction of the axis line L, the rotation axis direction X, and the extension direction of the line segment M in the same plane to intersect and form a right-angled triangle. Furthermore, the axis line L of the connecting bracket 324 when the rotating component 322 is in the first position can also be symmetrical to the axis line L of the connecting bracket 324 when the rotating component 322 is in the second position.

[0098] It is understandable that the angle formed by the intersection of the extension direction of the axis line L and the orthographic projection of the rotation axis direction X on the same plane can be selected according to the design requirements of the electronic device 10, and is not limited to the scheme of the above embodiment. At the same time, the extension direction of the line segment M and the orthographic projection of the rotation axis direction X on the same plane do not necessarily have to be perpendicular; it is sufficient that they can form a triangle together with the extension direction of the axis line L. Furthermore, the axis line L of the connecting bracket 324 when the rotating member 322 is in the first position can also be asymmetrically arranged with respect to the axis line L of the connecting bracket 324 when the rotating member 322 is in the second position.

[0099] Since multiple rotating components 320 are spaced apart on the same side of the fixed component 310, adjacent rotating components 320 can also form a triangular beam structure to further improve the stability of the rotating shaft mechanism 300. Figures 14 to 15 As shown, the extension directions of the two axial centerlines L of the two connecting brackets 324 of adjacent rotating components 320 intersect in the orthographic projection of the two axial centerlines L in the same plane. Since the extension directions of the two axial centerlines L also intersect in the orthographic projection of the rotation axis direction X in the same plane, the extension directions of the two axial centerlines L and the orthographic projection of the rotation axis direction X in the same plane can intersect to form a triangle. Simultaneously, the extension directions of the two line segments M of the two rotating parts 321 of the two adjacent rotating components 320 are perpendicular to the orthographic projection of the rotation axis direction X in the same plane, and intersect with the orthographic projections of the two axial centerlines L in the same plane, so that the orthographic projections of the two line segments M can become a beam connecting the axial centerlines L and the orthographic projections of the rotation axis direction X. That is, the rotating part 321 can act as a support arm (support beam) to support the connecting brackets 324. With this configuration, the two adjacent rotating components 320 can jointly form a triangular beam structure to further improve the stability of the rotating shaft mechanism 300, thereby enhancing the impact resistance of the rotating shaft mechanism 300 when the electronic device 10 is dropped.

[0100] Furthermore, the angles formed by the intersection of the extension directions of the two axial centerlines L of two adjacent connecting brackets 324 and the orthographic projections of the rotation axis direction X in the same plane can be complementary. That is, the two axial centerlines L of two adjacent connecting brackets 324 can also be symmetrically arranged about the width direction W to improve the motion consistency of the two adjacent rotating components 320. At the same time, the intersection of the orthographic projections of the extension directions of the two axial centerlines L of two adjacent connecting brackets 324 in the same plane also forms an angle greater than 90°, so that the intersection of the extension directions of the two axial centerlines L and the orthographic projections of the rotation axis direction X in the same plane can form an isosceles triangle with an obtuse angle, thereby enhancing the stability of the rotating shaft mechanism 300 while reducing the space occupied by the rotating shaft mechanism 300 in the width direction W.

[0101] In some embodiments, the two axis lines L of two adjacent connecting brackets 324 can also be arranged asymmetrically, and the included angle formed by the intersection of the orthographic projections of the two axis lines L in the same plane is not limited to greater than 90°. That is, the arrangement angle and position of two adjacent connecting brackets 324 can be selected according to the design requirements of the electronic device 10, as long as the two axis lines L of two adjacent connecting brackets 324 can together with the rotation axis direction X and the line segment M to form the aforementioned triangular beam structure. This embodiment does not limit this.

[0102] Please see Figures 16 to 18 , Figure 16 yes Figure 1 A schematic diagram of a partial cross-sectional structure of the central pivot mechanism 300 along VII-VII. Figure 17 yes Figure 2 A schematic diagram of a partial cross-sectional structure of the central pivot mechanism 300 along line IV-IV. Figure 18 yes Figure 6 A schematic diagram of the connection structure between the middle fixed component 310 and the middle rotating component 320. Figure 19 yes Figure 6 Another schematic diagram of the connection structure between the middle fixed component 310 and the middle rotating component 320.

[0103] like Figures 16 to 17 As shown, since the rotating component 322 is rotatably connected to the fixed component 310 (base 311) through the mounting groove 3111 (virtual axis), the rotating component 322 and the mounting groove 3111 need to be designed with sufficient fit W1 to meet the sliding stroke required for the rotating component 322 to rotate to the first position or the second position. At the same time, in order to improve the motion stability and reliability of the rotating component 322, the rotating component 322 and the mounting groove 3111 also need to be designed with redundant fit W2, so that the rotating component 322 can still maintain sufficient fit with the mounting groove 3111 in the second position, thereby reducing the probability that the rotating component 322 will disengage from the mounting groove 3111 due to insufficient fit. However, in the above scheme, the redundant fit amount W2 between the rotating part 322 and the mounting groove 3111 is often too large. The redundant fit amount W2 will also increase the space occupied by the rotating part 322 and the base 311 after assembly. Specifically, the width of the rotating part 322 and the base 311 in the width direction W increases, which is not conducive to the miniaturization of the rotating shaft mechanism 300.

[0104] To address the aforementioned problems, the rotating assembly 320 provided in this embodiment, in addition to including the rotating member 322, may further include a limiting member 327. For example... Figures 18 to 19As shown, the rotating member 322 is rotatably disposed within the mounting groove 3111, and the rotation trajectory of the rotating member 322 within the mounting groove 3111 can be a first arc H, allowing the rotating member 322 to rotate around the base 311 between a first position and a second position. Simultaneously, the fixing assembly 310 (base 311) also has a limiting groove 3112 formed on the side wall of the mounting groove 3111, and a limiting member 327 can be connected to the rotating member 322 and protrudes within the limiting groove 3112. Specifically, when the rotating member 322 slides along the groove wall of the mounting groove 3111, that is, when rotating between the first and second positions, the limiting member 327 is movable to allow the rotating member 322 to slide within the limiting groove 3112 and can engage with the groove wall of the limiting groove 3112 in the direction in which the rotating member 322 slides out of the mounting groove 3111.

[0105] Through the above-described configuration, the rotating shaft mechanism 300 in this embodiment can limit the sliding stroke of the rotating member 322 within the mounting groove 3111 by engaging the limiting member 327 with the groove wall of the limiting groove 3112. This prevents the rotating member 322 from dislodging from the mounting groove 3111 when it rotates to the second position, thereby further improving the motion stability and reliability of the rotating member 322. Furthermore, compared to a scheme that designs a redundant fit W2 between the rotating member 322 and the mounting groove 3111, this embodiment, by using the limiting member 327 and the limiting groove 3112 to limit the rotating member 322, can reduce the required redundant fit W2 between the rotating member 322 and the mounting groove 3111. This reduces the total fit between the rotating member 322 and the mounting groove 3111, thereby reducing the space occupied by the rotating member 322 and the base 311 after assembly. Specifically, the width of the rotating member 322 and the base 311 in the width direction W becomes narrower, thus achieving a miniaturized design of the rotating shaft mechanism 300.

[0106] Please combine Figures 18 to 19 See Figures 20 to 23 , Figure 20 yes Figure 18 A schematic diagram of the connection structure of the central base 311, rotating component 322, limiting component 327, and sliding component 328. Figure 21 yes Figure 20 A schematic diagram of the connection structure of the rotating component 322, the limiting component 327, and the sliding component 328. Figure 22 yes Figure 20 A schematic diagram of the structure of the two sliding parts 328. Figure 23 yes Figure 20 A schematic diagram of the structure of the middle part of the base 311.

[0107] To avoid restricting the sliding of the rotating component 322, the sliding trajectory of the limiting component 327 within the limiting groove 3112 can be a second arc P, and the centers of the first arc H and the second arc P can be the same. This ensures that the sliding of the rotating component 322 and the limiting component 327 is consistent, preventing the rotating component 322 from becoming stuck due to inconsistent sliding (the limiting component 327 abutting against the groove wall of the limiting groove 3112). The fact that the centers of the first arc H and the second arc P are the same also indicates that the base 311 requires high machining precision. That is, when machining the mounting groove 3111 and the limiting groove 3112 on the base 311, high machining precision must be maintained to control the error within a certain range to ensure that the centers of the first arc H and the second arc P are the same. If the machining accuracy is insufficient, it may affect the smooth sliding of the rotating part 322, or even cause the rotating part 322 to be directly stuck in the mounting groove 3111. This is detrimental to reducing machining difficulty and cost, as well as ensuring the movement stability of the rotating part 322.

[0108] To solve the above problems, the rotating assembly 320 may further include a slider 328, and the centers of the first arc H and the second arc P may be different. For example... Figures 18 to 20 As shown, the slider 328 is disposed within the mounting groove 3111 and can slide within the mounting groove 3111, and the sliding trajectory of the slider 328 is the first arc H. The rotating member 322 is slidably disposed on the slider 328, and the sliding direction N of the rotating member 322 (perpendicular to the axis Y) can also intersect the extension direction of the first arc H. When the slider 328 slides within the mounting groove 3111, the rotating member 322 is driven by the slider 328 to rotate around the base 311 between a first position and a second position, and the limiting member 327 is driven by the rotating member 322 to slide within the limiting groove 3112. Simultaneously, since the centers of the first arc H and the second arc P are different, the limiting member 327 will also abut against the wall of the limiting groove 3112. This allows the limiting member 327 to drive the rotating member 322 to slide relative to the sliding member 328 under the abutment of the wall of the limiting groove 3112, thereby avoiding the abutment between the limiting member 327 and the limiting groove 3112 and ensuring that the rotating member 322 can slide with the sliding member 328 within the mounting groove 3111. It is understood that when the centers of the first arc H and the second arc P are the same, the rotating assembly 320 may also include a sliding member 328.

[0109] With the above settings, the rotating shaft mechanism 300 can use the sliding of the rotating member 322 relative to the sliding member 328 to eliminate the influence of the inconsistent sliding trajectories of the sliding member 328 and the limiting member 327 on the movement of the rotating member 322. This not only improves the movement stability of the rotating member 322, but also allows the arc centers of the first arc H and the second arc P to be different. This helps to reduce the machining accuracy requirements of the base 311, thereby reducing the machining difficulty and cost of the base 311.

[0110] Furthermore, when the rotating member 322 is slidably mounted on the sliding member 328, the limiting member 327 can still be connected to the rotating member 322 and protrude into the limiting groove 3112. The limiting member 327 can engage with the groove wall of the limiting groove 3112 in the direction in which the sliding member 328 slides out of the mounting groove 3111, thus preventing the sliding member 328 from dislodging from the mounting groove 3111 when the rotating member 322 rotates to the second position. Simultaneously, since the limiting member 327 and the limiting groove 3112 cooperate to limit the sliding member 328, the amount of contact between the sliding member 328 and the mounting groove 3111 can be reduced, thereby reducing the space occupied by the sliding member 328 and the base 311 after assembly, thus achieving a miniaturized design of the rotating shaft mechanism 300.

[0111] Furthermore, the limiting member 327 engages with the groove wall of the limiting groove 3112 in the direction in which the rotating member 322 slides out of the sliding member 328, to prevent the rotating member 322 from disengaging from the sliding member 328. For example, the limiting groove 3112 has a first groove wall 31121 and a second groove wall 31122 located in the sliding direction of the limiting member 327 (that is, the extension direction of the second arc P). When the rotating member 322 is in the first position, the limiting member 327 can engage with the first groove wall 31121 to restrict the position of the sliding member 328 sliding into the mounting groove 3111 and the position of the rotating member 322 sliding into the sliding member 328. When the rotating member 322 is in the second position, the limiting member 327 can engage with the second groove wall 31122 to restrict the position of the sliding member 328 sliding out of the mounting groove 3111 and the position of the rotating member 322 sliding out of the sliding member 328. This configuration allows the limiting member 327 to cooperate with the groove wall of the limiting groove 3112 to limit the sliding of the sliding member 328 in the mounting groove 3111 and the sliding of the rotating member 322 on the sliding member 328, so as to prevent the rotating member 322 from having unnecessary movement that would affect the folding and unfolding of the electronic device 10.

[0112] Furthermore, when the rotating member 322 rotates from the first position to the second position, the limiting member 327 slides from the first groove wall 31121 to the second groove wall 31122. Specifically, when the limiting member 327 slides from the first groove wall 31121 to the second groove wall 31122, the sliding distance of the rotating member 322 relative to the sliding member 328 increases and then decreases, with the increasing and decreasing distances being equal. That is, when the limiting member 327 slides from the first groove wall 31121 to the middle position between the first groove wall 31121 and the second groove wall 31122, because the distance between the sliding trajectory of the limiting member 327 and the sliding trajectory of the sliding member 328 gradually increases, the groove wall of the limiting groove 3112 will abut against the limiting member 327, causing the rotating member 322 to slide a first distance in one direction relative to the sliding member 328. When the limiting member 327 slides from the aforementioned intermediate position to the second groove wall 31122, the distance between the sliding trajectory of the limiting member 327 and the sliding trajectory of the sliding member 328 gradually decreases. Therefore, the groove wall of the limiting groove 3112 will avoid the limiting member 327, allowing the limiting member 327 to drive the rotating member 322 to slide a first distance in the opposite direction relative to the sliding member 328 to reset. Through the above arrangement, the clearance space required to avoid the sliding of the rotating member 322 on the sliding member 328 can be reduced, thereby reducing the space occupied by the rotating member 322 and the sliding member 328 in the width direction W after assembly, thus realizing the miniaturization design of the rotating shaft mechanism 300.

[0113] In some embodiments, since the rotating member 322 can slide on the sliding member 328 to avoid contact with the wall of the limiting member 327 and the limiting groove 3112, that is, the sliding member 328 and the limiting member 327 will not restrict each other due to inconsistent sliding trajectories, the sliding trajectory of the limiting member 327 in the limiting groove 3112 is not limited to the second arc P. For example, the sliding trajectory of the limiting member 327 in the limiting groove 3112 can also be a straight line, and the limiting groove 3112 can be a straight groove, as long as the limiting member 327 can engage with the wall of the limiting groove 3112 to limit the sliding of the sliding member 328 and the rotating member 322. This embodiment does not limit this.

[0114] Furthermore, in order to achieve a sliding connection between the sliding member 328 and the rotating member 322, the sliding member 328 has a slot 3281 for the rotating member 322 to be inserted. For example... Figures 20 to 22As shown, the slot 3281 can penetrate the slider 328 in the sliding direction N of the rotating member 322 to reduce the space occupied by the slider 328 in the width direction W. Simultaneously, the slot 3281 can also penetrate the slider 328 on the side facing the limiting groove 3112 to form a slot 3282 that avoids the limiting member 327. That is, the limiting member 327 can protrude into the limiting groove 3112 through the slot 3282 and can slide relative to the slider 328 with the rotating member 322 through the slot 3282. Of course, in some embodiments, the slot 3281 may not penetrate the slider 328 in the sliding direction N of the rotating member 322; this embodiment does not limit this.

[0115] Furthermore, to achieve a sliding connection with the slider 328, the rotating member 322 may include a main body 3222 and a insertion part 3223. For example... Figures 21 to 22 As shown, the main body 3222 is connected to the insertion part 3223, which is slidably inserted into the slot 3281 and can drive the main body 3222 to slide in the width direction W. A limiting member 327 is provided on the side of the insertion part 3223 opposite to the main body 3222, and the limiting member 327 can be a structure independent of the insertion part 3223. For example, the limiting member 327 can be a pin rotatably connected to the insertion part 3223, allowing the limiting member 327 to roll within the limiting groove 3112, further improving the smoothness of the sliding within the limiting groove 3112. Alternatively, the limiting member 327 can be an arc-shaped slider or a cylindrical slider connected to the insertion part 3223 and possessing high wear resistance, thereby improving the wear resistance of the limiting member 327 within the limiting groove 3112. Of course, in some embodiments, the limiting member 327 may also be part of the insertion part 3223, as long as the limiting member 327 can slide within the limiting groove 3112. This embodiment does not limit this.

[0116] In some embodiments, the rotating member 322 may further include a sleeve portion 3224. For example... Figure 21 As shown, the sleeve portion 3224 is located on the side of the main body portion 3222 opposite to the insertion portion 3223, and the sleeve portion 3224 can be rotatably connected to the aforementioned fixed bracket 323. For example, the fixed bracket 323 may be provided with a connecting shaft, and the sleeve portion 3224 can be sleeved on the connecting shaft to realize the rotatable connection between the rotating member 322 and the fixed bracket 323. Of course, in some embodiments, the sleeve portion 3224 can also be replaced by the sliding portion 3221 in the aforementioned embodiment to realize the sliding connection between the rotating member 322 and the fixed bracket 323. This embodiment does not limit this.

[0117] Furthermore, to improve the stability of the fit between the rotating component 322 and the base 311, the base 311 may have two mounting slots 3111, and the rotating assembly 320 may include two sliding members 328 respectively disposed in the two mounting slots 3111. The rotating component 322 may include two insertion portions 3223 respectively inserted into the two sliding members 328, and the two insertion portions 3223 are slidably connected to the two sliding members 328 (that is, slidably inserted into the slots 3281), so as to improve the stability of the fit between the rotating component 322 and the base 311 by utilizing the two mounting slots 3111, the two sliding members 328, and the two insertion portions 3223. In this embodiment, the two mounting slots 3111, the two sliding members 328, and the two insertion portions 3223 may all be symmetrically arranged about the sliding direction N (or the width direction W) of the rotating component 322, that is, along the axial direction Y. Of course, in some embodiments, the two mounting slots 3111, the two sliding members 328, and the two plug-in portions 3223 may also be arranged asymmetrically, and this embodiment does not limit this.

[0118] Furthermore, the slider 328 has a first surface 3283 parallel to the sliding direction of the rotating member 322, and the mounting groove 3111 has a limiting groove 3112 formed on the sidewall facing the first surface 3283. Figures 21 to 23 As shown, the limiting member 327 can protrude from the first surface 3283 out of the sliding member 328 and further protrude into the limiting groove 3112. A portion of the limiting member 327 protruding into the limiting groove 3112 can also be cylindrical (like the pin mentioned above). Simultaneously, the slot 3281 can penetrate the first surface 3283, that is, the side of the sliding member 328 facing the limiting groove 3112, to form the aforementioned slot 3282 on the first surface 3283 to avoid obstructing the limiting member 327.

[0119] Furthermore, the slider 328 also has a second surface 3284 that is parallel to the sliding direction N of the rotating member 322 and is disposed opposite to the first surface 3283. For example... Figures 21 to 23As shown, the mounting groove 3111 has a guide portion 3113 on its sidewall facing the second surface 3284, and the sliding member 328 has a mating portion 3285 on the second surface 3284. The guide portion 3113 is spaced apart from the bottom wall of the mounting groove 3111, and the mating portion 3285 is slidably disposed between the guide portion 3113 and the bottom wall of the mounting groove 3111. The sliding trajectory of the mating portion 3285 coincides with the first arc H to prevent the mating portion 3285 from affecting the sliding of the sliding member 328. Simultaneously, when the limiting member 327 engages with the groove wall of the limiting groove 3112, at least a portion of the mating portion 3285 remains between the guide portion 3113 and the bottom wall of the mounting groove 3111. With this configuration, whether the rotating member 322 rotates to the first position or the second position, the sliding member 328 can maintain a stable engagement with the guide part 3113 through the mating part 3285, so as to guide and limit the sliding of the sliding member 328, thereby preventing the sliding member 328 from rotating with the extension direction of the limiting member 327 (such as a pin) as the axis.

[0120] In some embodiments, the design of the guide portion 3113 and the mating portion 3285 can be omitted, and the limiting member 327 can be the aforementioned arc-shaped slider protruding in the limiting groove 3112 to mate with the groove wall of the limiting groove 3112, thereby preventing the slider 328 from rotating about the extension direction of the limiting member 327. Of course, when the limiting member 327 is the aforementioned arc-shaped slider, the design of the guide portion 3113 and the mating portion 3285 can also be retained, or replaced with the limiting member 327 and the limiting groove 3112. That is, the mounting groove 3112 is provided on both opposite side walls of the mounting groove 3111, and the opposite ends of the limiting member 327 can be respectively provided on the first surface 3283 and the second surface 3284 of the slider 328, so as to protrude into the two limiting grooves 3112 respectively.

[0121] Please see Figures 24 to 25 , Figure 24 yes Figure 18 Another connection structure diagram of the central base 311, rotating component 322, limiting component 327, and sliding component 328. Figure 25 yes Figure 19 Another schematic diagram of the connection structure of the middle part base 311, rotating part 322, limiting part 327 and sliding part 328.

[0122] The following is a brief summary of the linkage relationship between the rotating component 322, the limiting component 327, and the sliding component 328 in this embodiment. For example... Figures 24 to 25As shown, when the rotating member 322 drives the sliding member 328 to slide within the mounting groove 3111, the rotating member 322 can rotate relative to the base 311 from a first position to a second position under the influence of the sliding member 328, and the limiting member 327 can slide within the limiting groove 3112 under the influence of the rotating member 322. Simultaneously, since the limiting member 327 abuts against the wall of the limiting groove 3112, the limiting member 327 will also drive the rotating member 322 to slide relative to the sliding member 328 under the abutment of the wall of the limiting groove 3112, and can reset after sliding relative to the sliding member 328 (see the aforementioned embodiment for details).

[0123] With the above settings, the rotating shaft mechanism 300 can use the sliding of the rotating member 322 relative to the sliding member 328 to eliminate the influence of the inconsistent sliding trajectories of the sliding member 328 and the limiting member 327 on the movement of the rotating member 322. This not only ensures the movement stability of the rotating member 322, but also reduces the machining accuracy requirements of the base 311 by using the inconsistent sliding trajectories of the sliding member 328 and the limiting member 327, thereby reducing the machining difficulty and cost of the base 311.

[0124] Please see Figures 26 to 27 , Figure 26 yes Figure 6 A schematic diagram of the connection structure of the middle fixing component 310, the rotating component 320, and the torque component 330. Figure 27 yes Figure 6 A schematic diagram of the connection structure of the middle fixed component 310, the rotating component 320 and the synchronization component 340.

[0125] To provide damping during the folding or unfolding of the first housing assembly 210 and the second housing assembly 220, the pivot mechanism 300 may further include a torque component 330. For example... Figure 26 As shown, the torque component 330 is disposed on the fixed component 310, and the torque component 330 is connected to the rotating component 321 and located in the sliding direction of the rotating component 321. When the rotating component 321 slides, the torque component 330 can undergo elastic deformation under the drive of the rotating component 321 to provide elastic force to the rotating component 321, thereby bringing a damping sensation to the rotation of the rotating component 321 on the rotating shaft 312.

[0126] Furthermore, the torque assembly 330 may include a first elastic element 331 and a second elastic element 332. Both the first elastic element 331 and the second elastic element 332 can be springs and are both sleeved on the rotating shaft 312. The first elastic element 331 is located on the side of the rotating member 321 closer to the rotating member 322, while the second elastic element 332 is located on the side of the rotating member 321 away from the rotating member 322. Simultaneously, the opposite ends of the first elastic element 331 are respectively connected to the base 311 and the side of the rotating member 321 closest to the rotating member 322, while the opposite ends of the second elastic element 332 are respectively connected to the base 311 and the side of the rotating member 321 away from the rotating member 322. When the rotating member 321 slides towards the rotating member 322, the first elastic member 331 can generate a compressive force due to the pressure of the rotating member 321, while the second elastic member 332 can generate a tensile force due to the pulling of the rotating member 321, so as to restrict the rotation of the rotating member 321 on the rotating shaft 312, thereby bringing a damping feeling to the rotation of the rotating member 321.

[0127] In some embodiments, the first elastic element 331 and the second elastic element 332 may not be limited to springs. For example, when the rotating member 321 is rotatably connected to the base 311 via the aforementioned first groove (virtual axis), the first elastic element 331 and the second elastic element 332 may also be elastic structures disposed within the aforementioned first groove, such as sheet metal or elastomers made of elastic materials such as silicone or rubber, and the first elastic element 331 and the second elastic element 332 may be respectively connected to opposite sides of the rotating member 321 in the sliding direction (rotation axis direction X). With this configuration, when the rotating member 321 slides in the first groove along the direction parallel to the axis Y, the first elastic element 331 and the second elastic element 332 can still generate the aforementioned compressive and tensile forces under the drive of the rotating member 321, so as to provide a damping sensation for the rotation of the rotating member 321 on the rotation axis 312.

[0128] Furthermore, to achieve rotational hovering of the rotating component 321, the torque assembly 330 may also include a cam 333. For example... Figure 26As shown, cam 333 is securely sleeved on rotating shaft 312 and located between first elastic element 331 and rotating element 321, and cam 333 can also mesh with rotating element 321. When rotating element 321 slides closer to rotating element 321, the first elastic element 331 generates a spring force (compression force) on cam 333, forcing cam 333 to abut against rotating element 321, thereby restricting the rotation of rotating element 321. Simultaneously, since cam 333 also meshes with rotating element 321, the meshing teeth of cam 333 and rotating element 321 can also limit the rotation of rotating element 321, allowing rotating element 321 to rotate and hover at different tooth positions. Furthermore, when the rotating member 321 rotates and is offset from the cam 333, the cam 333 will further compress the first elastic member 331 to increase the elastic force of the first elastic member 331 on the rotating member 321, thereby enhancing the damping sensation generated by the rotation of the rotating member 321.

[0129] With the above configuration, the sliding of the rotating component 321 on the rotating shaft 312 can cause the first elastic component 331 and the second elastic component 332 to undergo elastic deformation, providing elastic force to the rotating component 321 and thus providing damping for its rotation. Simultaneously, the cam 333, in conjunction with the rotating component 321, enables the rotating component 321 to hover at different angles while maintaining rotational damping. Furthermore, compared to a design where the rotating component 321 can only rotate, this embodiment has lower assembly requirements for the first elastic component 331 and the second elastic component 332. That is, in a design where the rotating component 321 can only rotate, the first elastic component 331 and the second elastic component 332 must be assembled in a compressed state; otherwise, elastic force cannot be generated on the rotating component 321.

[0130] To achieve synchronous rotation of the rotating components 320 on opposite sides of the fixed component 310, the rotating shaft mechanism 300 may further include a synchronization component 340. For example... Figure 27As shown, the synchronization component 340 may include: a first guide rod 341, a second guide rod 342, a first gear 343, and a second gear 344. The first guide rod 341 and the second guide rod 342 are both mounted on the base 311 and located between two rotating shafts 312. The first gear 343 and the second gear 344 are respectively sleeved on the first guide rod 341 and the second guide rod 342, and are rotatably connected to them. Simultaneously, the first gear 343 and the second gear 344 mesh with each other, and the first gear 343 also meshes with the rotating component 321 of the rotating component 320 located on one side of the base 311, while the second gear 344 also meshes with the rotating component 321 of the rotating component 320 located on the opposite side of the base 311. Furthermore, considering that the rotating component 321 also needs to slide on the rotating shaft 312, the first gear 343 and the second gear 344 can be designed to be relatively long in the rotational direction X to ensure that the rotating component 321 can still mesh with the first gear 343 and the second gear 344 after sliding. With the above arrangement, the first gear 343 and the second gear 344 can realize the linkage of the two rotating components 321 on opposite sides of the base 311, so that the rotating components 320 on opposite sides of the base 311 can rotate synchronously.

[0131] Please see Figures 28 to 29 , Figure 28 yes Figure 1 A schematic diagram of a partial cross-sectional structure of the central pivot mechanism 300 along line X-X. Figure 29 yes Figure 2 A schematic diagram of a partial cross-sectional structure of the central pivot mechanism 300 along XI-XI.

[0132] To support the display mechanism 100 together with the first housing assembly 210 and the second housing assembly 220, the pivot mechanism 300 may further include a support assembly 350. For example... Figures 28 to 29 As shown, the support assembly 350 may include a middle plate 351 and a side plate 352. The middle plate 351 can cover the side of the base 311 opposite to the shielding member 313 and, together with the base 311, form the aforementioned mounting groove 3111 to achieve a rotatable connection between the rotating member 322 and the base 311. Alternatively, the base 311 may independently form the aforementioned mounting groove 3111. The side plate 352 can be rotatably connected to multiple fixed supports 323 of multiple rotating assemblies 320 located on the same side of the base 311, and is located on the second side 3233 of the fixed supports 323. The side plate 352 can also be rollably connected to the rotating member 322. Furthermore, there can be two side plates 352, which can be symmetrically arranged on opposite sides of the middle plate 351 parallel to the axis Y, and respectively cooperate with multiple rotating assemblies 320 located on opposite sides of the base 311.

[0133] Furthermore, when the rotating member 322 is in the first position, the two side plates 352 can be flattened with the middle plate 351, and the side of the middle plate 351 facing away from the base 311 and the side plates 352 facing away from the fixed bracket 323 can together form a support surface 301, so as to support the display mechanism 100 by cooperating with the support surface 301 and the bearing surface 201. When the rotating member 322 is in the second position, the two side plates 352 can rotate as the fixed bracket 323 under the drive of the rotating member 322, and together with the middle plate 351, form a teardrop-shaped receiving space 302, so as to receive and avoid the part of the display mechanism 100 that bends with the side plates 352.

[0134] Furthermore, the side plate 352 is provided with a third sliding groove 3521, which can also be an arc-shaped groove. The fixed bracket 323 is provided with an arc-shaped structure 3234 located within the third sliding groove 3521 and capable of sliding within it. Simultaneously, the side plate 352 is also provided with a fourth sliding groove 3522, and the rotating member 322 also has a limiting shaft 3225 slidably disposed within the fourth sliding groove 3522. When the rotating member 322 rotates around the base 311, the fixed bracket 323 can move relative to the rotating member 322 under the drive of the first housing assembly 210 (see the aforementioned embodiment for details), thereby causing the side plate 352 to move relative to the rotating member 322. At this time, the limiting shaft 3225 can abut against the groove wall of the fourth slide 3522 and drive the side plate 352 to rotate relative to the fixed bracket 323 through the aforementioned third slide 3521 and arc structure 3234, so that the side plate 352 can rotate relative to the fixed bracket 323 in the direction of approaching or moving away from the second side 3233, so as to form the aforementioned support surface 301 together with the middle plate 351, or to form the aforementioned receiving space 302 together with the middle plate 351.

[0135] The rotating shaft mechanism 300 provided in this application allows the rotating member 322 to rotate around the fixed component 310 by slidably disposing the rotating member 322 within the mounting groove 3111 of the fixed component 310, with the sliding trajectory of the rotating member 322 being a first arc H. Simultaneously, a limiting groove 3112 is provided on the side wall of the mounting groove 3111, and the rotating member 322 also has a limiting member 327 protruding from the limiting groove 3112. This limiting member 327 is driven by the rotating member sliding within the limiting groove 3112 and can engage with the groove wall of the limiting groove 3112, thus limiting the sliding of the rotating member 322. With this configuration, the sliding of the rotating part 322 is limited by the cooperation of the limiting part 327 and the limiting groove 3112. Therefore, the amount of cooperation between the rotating part 322 and the mounting groove 3111 can be reduced, thereby reducing the space occupied by the rotating part 322 and the fixed component 310 after assembly, thus realizing the miniaturization design of the rotating shaft mechanism 300.
