BACKGROUND

[0003] With the continuous development and popularization of electronic devices, electronic devices have become an indispensable part of people's daily life and work, and people's requirements for electronic devices are also getting higher and higher. For example, some mobile phones add a rotating shaft mechanism on the basis of the original, so that the mobile phone can switch between flat and folded forms to bring different user experiences. At present, in order to reduce the bending degree of the screen of the folding mobile phone after folding, some manufacturers use a water drop rotating shaft scheme. That is, the rotating shaft mechanism of this type of rotating shaft mechanism can form a water drop-shaped accommodating space after folding to accommodate and avoid the folding area of the mobile phone screen. However, the rotating shaft mechanism in most water drop rotating shaft schemes has poor motion stability, which undoubtedly increases the failure rate of the rotating shaft mechanism, so how to improve the motion stability of the rotating shaft mechanism has become the main concern of industry personnel.

Similarly, the following embodiments are only some of the embodiments of the present application, and all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of the present application.

[0050] Reference to "an embodiment" in this application means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that "an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. Those skilled in the art will understand that embodiments described herein can be combined with other embodiments.

[0051] Please refer to FIG. 1 to FIG. 4, FIG. 1 is a structural schematic diagram of an electronic device 10 in a flat state according to an embodiment of the present application, FIG. 2 is a structural schematic diagram of the electronic device 10 in a folded state according to the embodiment of the present application, FIG. 3 is an exploded structural schematic diagram of the electronic device 10 according to the embodiment of the present application, and FIG. 4 is an exploded structural schematic diagram of a rotating shaft mechanism 300 according to the embodiment of the present application.

[0052] The electronic device 10 provided by the embodiments of the present application can be a foldable mobile phone, a foldable tablet computer, a foldable personal digital assistant, a foldable e-book reader, etc. Hereinafter, the electronic device 10 is exemplified as a foldable mobile phone. As shown in FIGS. 1-3, the electronic device 10 can include a display mechanism 100, a housing mechanism 200, and a hinge mechanism 300. The display mechanism 100 is arranged on the housing mechanism 200 and has flexibility, and can be folded with the housing mechanism 200. The hinge mechanism 300 is arranged on the housing mechanism 200 along an axis Y, and can support the unfolded display mechanism 100 together with the housing mechanism 200, and the housing mechanism 200 can be folded along the axis Y through the hinge mechanism 300. In the embodiments, the hinge mechanism 300 has high motion stability, which is beneficial to reduce the probability of failure of the hinge mechanism 300.

[0053] The display mechanism 100 has flexibility and can be folded with the housing mechanism 200 along the axis Y, and the display mechanism 100 can include a transparent cover plate, a touch panel, and a display panel arranged in sequence. The surface of the transparent cover plate can have a flat and smooth characteristic to facilitate the user to perform touch operations such as clicking, sliding, and pressing, and the transparent cover plate is made of a flexible material such as colorless polyimide (CPI). The touch panel is arranged between the transparent cover plate and the display panel, and is used to respond to the touch operation of the user and convert the corresponding touch operation into an electrical signal transmitted to the processor of the electronic device 10, so that the electronic device 10 can respond to the touch operation of the user. The display panel is mainly used to display a picture, and can be used as an interactive interface to instruct the user to perform the above-mentioned touch operation on the transparent cover plate, and the display panel can use an OLED (Organic Light-Emitting Diode) screen to realize the image display and folding function of the electronic device 10. In the embodiments, the transparent cover plate, the touch panel, and the display panel can be attached together by means of OCA (Optically Clear Adhesive), PSA (Pressure Sensitive Adhesive), etc.

[0054] In some embodiments, the display mechanism 100 can also not be limited to the laminated structure as shown in the foregoing embodiments. That is, the specific structure of the display mechanism 100 can also be adaptively selected according to the design requirements of the electronic device 10, as long as the display mechanism 100 is flexible and capable of being folded along the axis Y, which is not limited in the present embodiment. In addition, in some embodiments, when the electronic device 10 is a folding device without display requirements, the design of the display mechanism 100 can also be omitted. In the present application, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally also include steps or units not listed, or can optionally also include other steps or units inherent to these processes, methods, products or devices.

[0055] The housing mechanism 200 is capable of being folded along the axis Y by the hinge mechanism 300 to drive the display mechanism 100 to be folded along the axis Y. As shown in FIGS. 1-3, 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 hinge mechanism 300 parallel to the axis Y. At the same time, the first housing assembly 210, the second housing assembly 220 and the hinge mechanism 300 are also capable of being unfolded to support the display mechanism 100 placed thereon, thereby maintaining the flatness of the display mechanism 100 after unfolding. In addition, the first housing assembly 210 and the second housing assembly 220 are also capable of being folded along the axis Y by the hinge mechanism 300 to drive the display mechanism 100 to be folded along the axis Y, thereby switching the electronic device 10 from the unfolded state (shown in FIG. 1) to the folded state (shown in FIG. 2). Similarly, the first housing assembly 210 and the second housing assembly 220 can also be unfolded by the hinge mechanism 300 to switch the electronic device 10 from the folded state back to the unfolded state.

[0056] Exemplarily, the first housing assembly 210 and the second housing assembly 220 each has a bearing surface 201 arranged towards the display mechanism 100, and when the electronic device 10 is in the unfolded state, the two bearing surfaces 201 can cooperate with the rotating shaft mechanism 300 to support the unfolded display mechanism 100, so as to ensure the flatness of the display mechanism 100 in the unfolded state. For example, the two bearing surfaces 201 can be planes and located in the same plane, so as to improve the consistency of the two bearing surfaces 201 in supporting the display mechanism 100. Of course, in some embodiments, the bearing surface 201 can not be a complete plane, and the bearing surface 201 can have some protrusions or recesses, as long as the flatness of the bearing surface 201 can be maintained within a certain range and the display mechanism 100 can be supported, so that the display mechanism 100 has sufficient flatness in the unfolded state, which is not limited in the present embodiment.

[0057] Further, 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, so as to protect the display mechanism 100. Meanwhile, the first housing assembly 210 and the second housing assembly 220 can also be used to mount various functional devices required by the electronic device 10, such as batteries, microphones, speakers, cameras, and mainboards, and the functional devices mounted on the first housing assembly 210 and the functional devices mounted on the second housing assembly 220 can be the same or partially the same. For example, the first housing assembly 210 and the second housing assembly 220 can each have a battery mounted thereon, so as to supply power to the functional devices mounted on the first housing assembly 210 and the second housing assembly 220, respectively.

[0058] Further, the first housing assembly 210 and the second housing assembly 220 can also be symmetrically arranged about the axis Y, that is, the axis Y can be a symmetric folding 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 can not be limited to being symmetrically arranged about the axis Y, that is, the axis Y can also be an asymmetric folding line of the electronic device 10, as long as the first housing assembly 210 and the second housing assembly 220 can be folded along the axis Y. In addition, the axis Y can not only be longitudinally placed as shown in FIGS. 1 and 2, so that the electronic device 10 can be folded left and right based on the axis Y, but also can be transversely placed, so that the electronic device 10 can be folded up and down based on the axis Y. The terms “first”, “second”, “third” in the present application are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by “first”, “second”, “third” can explicitly or implicitly include at least one of the features.

[0059] The hinge mechanism 300 is arranged on the shell mechanism 200 along the axis Y, and the shell mechanism 200 can also be folded along the axis Y through the hinge mechanism 300. As shown in FIGS. 3-4, the hinge mechanism 300 can include a fixed assembly 310, a rotating assembly 320, and a supporting assembly 330. The fixed assembly 310 is arranged between the first shell assembly 210 and the second shell assembly 220 along the axis Y, and the fixed assembly 310 is provided with the rotating assembly 320 on opposite sides parallel to the axis Y, so as to be connected with the first shell assembly 210 and the second shell assembly 220 through the rotating assemblies 320 on the opposite sides, respectively. Meanwhile, the rotating assembly 320 can also rotate around the fixed assembly 310, so that the first shell assembly 210 and the second shell assembly 220 can be folded or unfolded along the axis Y through the rotation of the rotating assembly 320. The supporting assembly 330 is arranged on the side of the fixed assembly 310 and the rotating assembly 320 close to the display mechanism 100, and can support the display mechanism 100 in cooperation with the aforementioned bearing surface 201. The corresponding structural member in the supporting assembly 330 can also move in cooperation with the rotating member 322 and the fixed bracket 323, so as to drive the display mechanism 100 to fold in cooperation with the first shell assembly 210 and the second shell assembly 220. In this embodiment, the rotating assembly 320 has the advantage of high movement stability, which is conducive to improving the movement stability of the hinge mechanism 300, so as to reduce the probability of failure of the hinge mechanism 300.

[0060] Please refer to FIGS. 5-8 in combination with FIG. 4. FIG. 5 is a partial structural schematic view of the fixed assembly 310 in FIG. 4, FIG. 6 is a connection structural schematic view of the fixed assembly 310 and the rotating assembly 320 in FIG. 4 in the unfolded state, FIG. 7 is a connection structural schematic view of the fixed assembly 310 and the rotating assembly 320 in FIG. 4 in the folded state, and FIG. 8 is a partial cross-sectional structural schematic view of the fixed assembly 310 and the rotating assembly 320 in FIG. 6 along the X-X.

[0061] The fixing assembly 310 can be used to connect and fix the rotating assembly 320 and the supporting assembly 330 described above, and the fixing assembly 310 can include a base 311. As shown in FIGS. 5-7, the base 311 can be disposed between the first housing assembly 210 and the second housing assembly 220 along the axis Y, and the base 311 is provided with the rotating assembly 320 on opposite sides parallel to the axis Y and rotationally connected with the rotating assembly 320 on the opposite sides. For example, the base 311 can be provided with a first arc-shaped groove 3111, and the first arc-shaped groove 3111 can cooperate with the corresponding part of the rotating assembly 320 to realize the rotational connection between the rotating assembly 320 and the base 311. That is, the part of the rotating assembly 320 corresponding to the first arc-shaped groove 3111 can be disposed in the first arc-shaped groove 3111 and can slide in the first arc-shaped groove 3111, and the sliding track of the part of the rotating assembly 320 corresponding to the first arc-shaped groove 3111 is an arc, so as to realize the rotational connection between the rotating assembly 320 and the base 311.

[0062] Through the above arrangement, the rotating assembly 320 can be rotationally connected with the base 311 by using the virtual shaft formed by the first arc-shaped groove 3111, which is conducive to reducing the stacking height of the rotating assembly 320 and the base 311 in the thickness direction Z, so as to realize the miniaturization of the rotating shaft mechanism 300 in the thickness direction Z, thereby reducing the limitation of the rotating shaft mechanism 300 on the thinness of the electronic device 10. In the present embodiment, the aforementioned thickness direction Z refers to the direction in which the first housing assembly 210 and the second housing assembly 220 approach or move away from the display mechanism 100 in the unfolded state, and the thickness direction Z can also be perpendicular to the extension direction of the aforementioned bearing surface 201 and the axis Y.

[0063] Further, the number of the base 311 can also be multiple (as shown in FIG. 4), and the multiple bases 311 can be disposed between the first housing assembly 210 and the second housing assembly 220 along the axis Y. Among them, the spacing between any two adjacent bases 311 of the multiple bases 311 can be the same or different, and the spacing space between the adjacent two bases 311 can be used for wiring (such as a flexible circuit board), so as to realize the electrical connection between the functional devices respectively mounted on the first housing assembly 210 and the second housing assembly 220. For example, the number of the base 311 can be three, and the three bases 311 can be disposed at the top, the middle and the bottom of the first housing assembly 210 and the second housing assembly 220 along the axis Y, respectively, and the spacing between any two adjacent bases 311 of the three bases 311 is the same. In the description of the present application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise specifically limited.

[0064] In some embodiments, the number of pedestals 311 can also not be limited to three, and the number of pedestals 311 can also be two, four, five, or more. That is, the number of pedestals 311 can be adaptively selected according to the design requirements of the electronic device 10, and only multiple pedestals 311 need to be spaced along the axis Y and arranged between the first housing assembly 210 and the second housing assembly 220, and the present embodiment does not limit this.

[0065] Further, each pedestal 311 can be provided with a rotating assembly 320 on opposite sides parallel to the axis Y, so that the same side of the fixed assembly 310 parallel to the axis Y can have the same number of rotating assemblies 320 as the pedestals 311. At the same time, since the multiple pedestals 311 are spaced, the multiple rotating assemblies 320 can also be spaced on the same side of the fixed assembly 310. For example, when the number of pedestals 311 is three, the side of the fixed assembly 310 parallel to the axis Y can be provided with three spaced rotating assemblies 320, and the other opposite side parallel to the axis Y can also be provided with three spaced rotating assemblies 320, so that the first housing assembly 210 and the second housing assembly 220 can be rotatably connected to the fixed assembly 310 through the three rotating assemblies 320, to improve the stability of the folding or flattening of the first housing assembly 210 and the second housing assembly 220. In addition, the two rotating assemblies 320 located on opposite sides of the pedestal 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 assemblies 320 relative to the pedestal 311.

[0066] In some embodiments, each pedestal 311 parallel to the axis Y can also not be limited to one rotating assembly 320 on opposite sides. That is, one side of the pedestal 311 parallel to the axis Y can be provided with two spaced rotating assemblies 320, and the other opposite side can also be provided with two, three, or more spaced rotating assemblies 320, and only each pedestal 311 parallel to the axis Y is provided with a rotating assembly 320 on opposite sides, and the present embodiment does not limit this. In addition, the rotating assemblies 320 located on opposite sides of the pedestal 311 parallel to the axis Y can be symmetrically arranged about the axis Y, or asymmetrically arranged on opposite sides of the pedestal 311 parallel to the axis Y, and the present embodiment does not limit this.

[0067] In some embodiments, the plurality of bases 311 can also be connected to form a whole, to constitute a longer base 311 (equivalent to the number of bases 311 being one). Among them, since there is no interval space formed by the plurality of bases 311 arranged along the axis Y, the longer base 311 can also form a via for wiring to realize the electrical connection between the functional devices respectively mounted on the first shell assembly 210 and the second shell assembly 220. At the same time, the longer base 311 can be provided with at least one rotating assembly 320 on the opposite sides parallel to the axis Y, and the number of rotating assemblies 320 located on the opposite sides of the longer base 311 parallel to the axis Y can be the same or different, and can be symmetrically arranged or asymmetrically arranged about the axis Y.

[0068] Further, the fixing assembly 310 can also include a rotating shaft 312. As shown in FIGS. 5-7, the rotating shaft 312 is arranged on the base 311, and the rotating shaft direction X of the rotating shaft 312 is parallel to the extension direction of the axis Y. Among them, the corresponding structure of the rotating assembly 320 can be sleeved on the rotating shaft 312 and rotationally connected with the rotating shaft 312, and the rotating shaft direction X of the rotating assembly 320 rotating through the rotating shaft 312 is also parallel to the rotating shaft direction of the rotating assembly 320 rotating through the first arc-shaped slot 3111. At the same time, since the base 311 is provided with one rotating assembly 320 on the opposite sides parallel to the axis Y, the base 311 can also be provided with two rotating shafts 312, and the corresponding structures of the two rotating assemblies 320 can be sleeved on the two rotating shafts 312, respectively, to rotationally connect the rotating shaft 312 with the base 311. In addition, the two rotating shafts 312 can be symmetrically arranged on the base 311 about the axis Y, to improve the consistency of the rotating assemblies 320 on the opposite sides of the base 311 rotating.

[0069] In some embodiments, the two rotating shafts 312 can also be asymmetrically arranged on the base 311, as long as the rotating assembly 320 can be rotationally connected with the base 311 through the rotating shaft 312, which is not limited in the present embodiment. All directional indications (such as up, down, left, right, front, back, etc.) in the present embodiment are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0070] In some embodiments, when the number of the base 311 is multiple, the two rotating shafts 312 can be designed to be longer and arranged through the multiple bases 311 to cooperate with the rotating assemblies 320 on the multiple bases 311, so as to simplify the structure of the rotating shaft mechanism 300. Alternatively, the two rotating shafts 312 can also be broken into multiple short rotating shafts with the same number as the rotating assemblies 320, and the multiple short rotating shafts can be arranged in pairs on the multiple bases 311 to cooperate with the rotating assemblies 320 on the multiple bases 311, so as to reduce 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 broken into multiple short rotating shafts and arranged on the base 311, and the present embodiment does not limit this.

[0071] Further, the fixing assembly 310 can further include a shielding member 313. As shown in FIGS. 5 to 7, the shielding member 313 is arranged on one side of the base 311 and connected with the base 311 to fix the base 311. Meanwhile, the edge of the shielding member 313 can also be protruded in the direction away from the shielding member 313 of the base 311, so that the shielding member 313 can also surround to form a shielding space 3131 accommodating the base 311. When the electronic device 10 is in the unfolded state, the first housing assembly 210 and the second housing assembly 220 can be spliced on the side of the shielding member 313 away from the base 311 to shield the shielding member 313. Meanwhile, when the electronic device 10 is in the folded state, the first housing assembly 210 and the second housing assembly 220 can be respectively connected with the opposite sides (protruded edges) of the shielding member 313 parallel to the axis Y, and together with the shielding member 313 form part of the appearance structure of the electronic device 10 to shield the internal structure of the electronic device 10 by the shielding member 313.

[0072] In some embodiments, the shielding member 313 can also be part of the base 311, rather than an independent structure from the base 311. For example, when the number of the base 311 is multiple, the multiple bases 311 can be arranged in the shielding space 3131 surrounded by the shielding member 313 along the axis Y to shield and fix the multiple bases 311 by the shielding member 313. Meanwhile, the multiple bases 311 and the shielding member 313 can be integrally manufactured by processes such as in-mold injection, so that the multiple bases 311 and the shielding member 313 can be formed as one body. When the multiple bases 311 and the shielding member 313 are formed as one body, the multiple bases 311 and the shielding member 313 can also together form the aforementioned longer base 311 in the embodiments.

[0073] The rotating assembly 320 is rotationally connected with the fixed assembly 310, and the first shell assembly 210 and the second shell assembly 220 can be folded or flattened through rotation of the rotating assembly 320 on the fixed assembly 310. Hereinafter, only the rotating assembly 320 connecting the first shell assembly 210 and the fixed assembly 310 will be described. As shown in FIGS. 6-7, the rotating assembly 320 can include a rotating piece 321, a rotating piece 322, and a fixed bracket 323. The rotating piece 321 is arranged on the side of the fixed assembly 310 parallel to the axis Y and is rotationally connected with the fixed assembly 310. The rotating piece 322 and the rotating piece 321 are located on the same side of the fixed assembly 310 and are rotationally connected with the fixed assembly 310, and the rotation axis direction of the rotating piece 322 is parallel to the rotation axis direction X of the rotating piece 321. The fixed bracket 323 is slidingly connected with the rotating piece 321 and the rotating piece 322, respectively, and is connected with the first shell assembly 210, and the sliding direction of the fixed bracket 323 on the rotating piece 321 and the rotating piece 322 is not parallel to the normal projection of the reference surface 3001 (perpendicular to the rotation axis direction X).

[0074] Further, when the user bends the first shell assembly 210 and the second shell assembly 220 to fold, the first shell assembly 210 and the second shell assembly 220 can drive the rotating piece 322 to rotate around the fixed assembly 310 through the fixed bracket 323, to realize the rotating folding of the first shell assembly 210 and the second shell assembly 220. During this process, that is, the process of the fixed bracket 323 rotating around the fixed assembly 310 with the rotating piece 322, the rotating piece 321 can rotate around the fixed assembly 310 driven by the fixed bracket 323, the fixed bracket 323 can also slide relative to the rotating piece 322, and because the rotation axis directions of the rotating piece 321 and the rotating piece 322 are parallel (the rotating trajectories are inconsistent), the fixed bracket 323 can also slide relative to the rotating piece 321, to realize the linkage among the rotating piece 321, the rotating piece 322, and the fixed bracket 323.

[0075] Specifically, the rotating piece 321 can be sleeved on the rotating shaft 312 and can rotate around the base 311 with the rotation axis direction X as the axis direction, to realize the rotational connection of the rotating piece 321 and the fixed assembly 310. Meanwhile, the part of the rotating piece 321 away from the rotating shaft 312 can be slidingly inserted into the fixed bracket 323, and the sliding direction of the rotating piece 321 is perpendicular to the rotation axis direction X, to realize the sliding connection with the fixed bracket 323. In addition, when the fixed bracket 323 rotates around the base 311 with the rotating piece 322, the rotating piece 321 can rotate around the base 311 driven by the fixed bracket 323 and slide relative to the fixed bracket 323, to link with the rotating piece 322 and the fixed bracket 323.

[0076] In some embodiments, the rotating member 321 can be connected with the base 311 through the rotating shaft 312, or the rotating member 321 can be connected with the base 311 through a virtual shaft. That is, the base 311 can be provided with a second arc-shaped slot similar to the first arc-shaped slot 3111, the virtual shaft formed by the first arc-shaped slot 3111 is parallel to the virtual shaft formed by the second arc-shaped slot, and a part of the rotating member 321 is slidably arranged in the second arc-shaped slot, so that the rotating member 321 is rotatably connected with the base 311 through the virtual shaft formed by the second arc-shaped slot.

[0077] Further, the rotating member 321 can be slidably connected with the corresponding structure of the supporting assembly 330, and can push the corresponding structure of the supporting assembly 330 to move. As shown in FIG. 6, the rotating member 321 is provided with a connecting part 3211 connected with the corresponding structure of the supporting assembly 330. The connecting part 3211 is slidably arranged on the corresponding structure of the supporting assembly 330 and is in point contact (real high pair) with the corresponding structure of the supporting assembly 330. Meanwhile, the connecting part 3211 can slide relative to the fixed support 323 in the first sliding direction N, and after sliding, the connecting part 3211 can abut against the corresponding structure of the supporting assembly 330 to push the corresponding structure of the supporting assembly 330 to move.

[0078] In some embodiments, the rotating member 321 can be divided into a first rotating part 3213 and a second rotating part 3214. As shown in FIG. 6, the first rotating part 3213 and the second rotating part 3214 are sleeved on the rotating shaft 312, the first rotating part 3213 is located between the second rotating part 3214 and the rotating member 322, and the first rotating part 3213 and the second rotating part 3214 are slidably inserted into the fixed support 323. When the fixed support 323 rotates around the base 311 with the rotating member 322, the first rotating part 3213 and the second rotating part 3214 can rotate around the base 311 synchronously with the fixed support 323 and slide relative to the fixed support 323. Meanwhile, the first rotating part 3213 and the second rotating part 3214 are provided with the connecting part 3211. For example, the connecting part 3211 can include a first connecting part 3211a and a second connecting part 3211b (equivalent to two connecting parts 3211), the first connecting part 3211a is arranged on the first rotating part 3213, and the second connecting part 3211b is arranged on the second rotating part 3214.

[0079] Further, the two rotating assemblies 320 located on opposite sides of the base 311 can also rotate synchronously around the base 311. For example, the rotating members 321 of the two rotating assemblies 320 located on opposite sides of the base 311 are provided with a synchronous assembly 340, and the synchronous assembly 340 can include two synchronous gears 341 engaged with each other, and the two synchronous gears 341 can also be engaged with the rotating members 321 of the two rotating assemblies 320 respectively, so that the rotating members 321 of the two rotating assemblies 320 can be linked through the two synchronous gears 341 to realize synchronous rotation of the two rotating assemblies 320 on opposite sides of the base 311. In this embodiment, the base 311 can be provided with a guide rod for sleeving the synchronous gears 341, so that the two synchronous gears 341 can be fixed on the base 311 to be engaged with the rotating members 321 of the two rotating assemblies 320 respectively. In addition, when the rotating member 321 is disassembled into the first rotating part 3213 and the second rotating part 3214, the two synchronous gears 341 can be engaged with the second rotating parts 3214 of the two rotating members 321 respectively.

[0080] The rotating member 322 is rotationally connected with the fixed assembly 310 and can rotate between the first position and the second position around the fixed assembly 310. As shown in FIGS. 6-7, the rotating member 322 and the rotating member 321 are spaced apart and located on the same side of the base 311, and part of the rotating member 322 is located in the first arc-shaped groove 3111 and can slide in the first arc-shaped groove 3111, so that the rotating member 322 can be rotationally connected with the base 311 by using the virtual shaft formed by the first arc-shaped groove 3111 to rotate between the first position and the second position. At the same time, the rotation axis direction of the rotating member 322 is also parallel to the rotation axis direction X of the rotating member 321. When the rotating member 322 is in the first position, the first shell assembly 210 and the second shell assembly 220 can be unfolded (the electronic device 10 is in an unfolded state). When the rotating member 322 is in the second position, the first shell assembly 210 and the second shell assembly 220 can be folded (the electronic device 10 is in a folded state).

[0081] In some embodiments, in addition to being rotationally connected with the base 311 through the first arc-shaped groove 3111, the rotating member 322 can also be rotationally connected with the base 311 through an entity shaft such as the rotation shaft 312, as long as the rotation axis directions of the rotating member 322 and the rotating member 321 are parallel, which is not limited in this embodiment.

[0082] The fixed support 323 is in sliding connection with the rotating member 321, and can drive the rotating member 321 to rotate around the base 311 when the fixed support 323 rotates around the base 311 with the rotating member 322. As shown in FIGS. 6 and 7, the fixed support 323 has a slot 3231 for the rotating member 321 to be inserted, and the rotating member 321 can be slidably inserted into the slot 3231. The slot 3231 can also partially penetrate the fixed support 323 towards the side of the support assembly 330, so that part of the rotating member 321 can be exposed on the side of the fixed support 323 facing the support assembly 330, and the cooperation part 3211 can be arranged on the part of the rotating member 321 exposed outside, so as to cooperate with the support assembly 330. When the fixed support 323 rotates around the base 311 with the rotating member 322, the fixed support 323 can drive the rotating member 321 to rotate around the base 311 through the slot wall of the slot 3231. Since the rotation axis direction of the rotating member 321 is parallel to the rotation axis direction of the rotating member 322 (the rotation trajectories are different), the fixed support 323 can also slide relative to the rotating member 321 in the first sliding direction N.

[0083] Further, the fixed support 323 can also be in sliding connection with the rotating member 322, and the sliding direction of the fixed support 323 on the rotating member 321 and the rotating member 322 is not parallel in the orthogonal projection in the reference surface 3001. As shown in FIGS. 6 and 8, the fixed support 323 is provided with a sliding groove 3232, and the rotating member 322 has a sliding part 3221 located in the sliding groove 3232. The sliding part 3221 can slide in the sliding groove 3232, and the sliding trajectory of the sliding part 3221 in the sliding groove 3232 can be a straight line. The sliding direction of the sliding part 3221 in the sliding groove 3232 can be the second sliding direction M, and the orthogonal projection of the second sliding direction M and the first sliding direction N in the same plane (the reference surface 3001 perpendicular to the axis Y) is not parallel. When the fixed support 323 rotates around the base 311 with the rotating member 322, the fixed support 323 can also slide relative to the rotating member 322 under the driving of the first housing assembly 210 to adjust the position of the first housing assembly 210. In this way, the first housing assembly 210 and the second housing assembly 220 can rotate to adjust their positions relative to the rotating member 322 when folding, so as to avoid the first housing assembly 210 and the second housing assembly 220 being limited by the rotation angle of the rotating member 322, thereby ensuring that the first housing assembly 210 and the second housing assembly 220 can be combined without gaps.

[0084] In some embodiments, the sliding track of the sliding part 3221 in the sliding groove 3232 can also not be limited to be a straight line. For example, the sliding groove 3232 can also be an arc-shaped groove, and the sliding part 3221 can still be arranged in the sliding groove 3232 and slide in the sliding groove 3232, and the sliding track of the sliding part 3221 in the sliding groove 3232 is an arc, so that the rotating part 322 can rotate relative to the fixed support 323. At this time, the fixed support 323 can be driven by the first shell assembly 210 to rotate relative to the rotating part 322, so that the first shell assembly 210 and the second shell assembly 220 can slide relative to the rotating part 322 to adjust the positions of the first shell assembly 210 and the second shell assembly 220, to ensure that the first shell assembly 210 and the second shell assembly 220 can be combined without gaps when being folded.

[0085] As shown in FIG. 8, in order to reduce the thickness of the fixed support 323, the sliding groove 3232 generally penetrates the fixed support 323 in the sliding direction of the sliding part 3221, which can cause the sliding stroke of the sliding part 3221 in the sliding groove 3232 to be unlimited, and the sliding part 3221 can be possibly detached from the sliding groove 3232 after sliding, which greatly reduces the motion stability of the rotating shaft mechanism 300. Based on this, the rotating part 321 is connected with the rotating part 322 in a rolling manner in the present embodiment, so as to indirectly control the relative sliding of the rotating part 322 and the fixed support 323 by using the motion stroke of the rotating part 321 on the rotating part 322, to constrain the sliding of the sliding part 3221 in the sliding groove 3232, thereby avoiding the sliding part 3221 from being detached from the sliding groove 3232 after sliding, and improving the motion stability of the rotating shaft mechanism 300.

[0086] Please refer to FIGS. 9-11. FIG. 9 is a partial enlarged view of A in FIG. 6, FIG. 10 is a partial sectional view of the fixed assembly 310 and the rotating assembly 320 along V-V in FIG. 6, and FIG. 11 is a partial sectional view of the fixed assembly 310 and the rotating assembly 320 along V-V in FIG. 7.

[0087] The rolling connection between the rotating member 321 and the rotating member 322 is further described below. As shown in FIGS. 9-11, the rotating member 321 has a first stop portion 3215 on the fixed assembly 310 (the base 311), and the rotating member 322 has a second stop portion 3222 on the fixed assembly 310 (the base 311). The first stop portion 3215 is located on the side of the rotating member 321 close to the rotating member 322, and the second stop portion 3222 is located on the side of the rotating member 322 close to the rotating member 321, and is arranged opposite to the first stop portion 3215 in the direction parallel to the axis Y, and the first stop portion 3215 is also in rolling connection with the second stop portion 3222. In this embodiment, the base 311 and the decorative member 313 can be an integral structure (hereinafter referred to as the base 311), and part of the first stop portion 3215 and the second stop portion 3222 can be accommodated in the shielding space 3131, so as to reduce the space occupied by the first stop portion 3215 and the second stop portion 3222 outside the shielding space 3131, which is beneficial to the miniaturization design of the rotating shaft mechanism 300.

[0088] When the fixed support 323 drives the rotating member 322 to rotate around the fixed assembly 310, the rotating member 321 is driven by the fixed support 323 to rotate around the fixed assembly 310, and the fixed support 323 slides relative to the rotating member 321 and the rotating member 322, while the first stop portion 3215 can rotate with the rotating member 321, and the second stop portion 3222 can rotate with the rotating member 322 and can roll relative to the first stop portion 3215. In this way, the relative movement of the first stop portion 3215 and the second stop portion 3222 can be used to control the sliding of the rotating member 322 on the fixed support 323, so as to constrain the sliding of the rotating member 322 on the fixed support 323, thereby improving the motion stability of the rotating shaft mechanism 300.

[0089] Further, the first stop portion 3215 is provided with a stop member 324, and the second stop portion 3222 is provided with a stop groove 3223. The stop member 324 is rollingly arranged in the stop groove 3223, and when the first stop portion 3215 and the second stop portion 3222 rotate with the rotating member 321 and the rotating member 322 respectively, the stop member 324 can roll in the stop groove 3223 and can be clamped with the groove wall of the stop groove 3223 after rolling. In this way, the clamping of the stop member 324 with the groove wall of the stop groove 3223, that is, the movement stroke of the stop member 324 in the stop groove 3223, can be used to constrain the relative sliding of the rotating member 322 and the fixed support 323, thereby improving the motion stability of the rotating shaft mechanism 300.

[0090] Further, when the rotating member 322 is rotated from the first position to the second position, the stop member 324 can slide in the first direction H in the stop slot 3223 and can be engaged with the slot wall of the stop slot 3223 in the first direction H. When the rotating member 322 is rotated from the second position to the first position, the stop member 324 can slide in the second direction L opposite to the first direction H in the stop slot 3223 and can be engaged with the slot wall of the stop slot 3223 in the second direction L. In the above movement process, since the stop member 324 can be engaged with the slot wall of the stop slot 3223 in two opposite directions, when the rotating member 322 is rotated to the first position or the second position, the rotating member 321 will be limited by the engagement of the stop member 324 and the slot wall of the stop slot 3223 and cannot continue to rotate around the base 311. Similarly, the fixed support 323 linked with the rotating member 321 will also be limited by the rotating member 321 and cannot continue to drive the rotating member 322 to rotate around the base 311 and slide relative to the rotating member 322, so as to realize the constraint of the relative sliding of the rotating member 322 and the fixed support 323.

[0091] Limited by the basic sliding stroke required for the rotation of the rotating shaft mechanism 300, that is, the movement stroke of the stop member 324 in the stop slot 3223, the second stop portion 3222 often needs to be designed to be large enough to open the stop slot 3223 with sufficient sliding space. In particular, when the rotating member 322 is in the first position, the part of the second stop portion 3222 engaged with the stop member 324 in the first direction H, that is, the part of the stop slot 3223 engaged with the stop member 324 in the first direction H, will protrude a higher height on the base 311, which is not conducive to reducing the thickness of the rotating shaft mechanism 300 in the thickness direction Z of the electronic device 10.

[0092] To solve the above problems, the stop groove 3223 in the embodiment can also pass through the second stop portion 3222 in the first direction H and form a notch 3224 on the second stop portion 3222, which is in communication with the outside of the stop groove 3223. When the rotating member 322 is in the second position, to avoid the stop member 324 from escaping from the stop groove 3223 at the notch 3224, the stop member 324 can be clamped with the groove wall of the stop groove 3223 adjacent to the notch 3224, and part of the area of the stop member 324 can also be arranged to protrude out of the stop groove 3223 from the notch 3224. For example, the stop member 324 can be arranged in a cylindrical shape (such as a pin shaft) and can be arranged to roll in the stop groove 3223, and the diameter of the stop member 324 is smaller than the caliber of the notch 3224, so that the stop member 324 can be arranged to protrude out of the stop groove 3223 while being clamped with the groove wall of the stop groove 3223 adjacent to the notch 3224. In this way, the basic sliding stroke required by the stop member 324 can be ensured (without affecting the rotation of the rotating member 322 between the first position and the second position), and part of the structure of the second stop portion 3222 in the first direction H is omitted to reduce the height of the second stop portion 3222 protruding from the base 311 when the rotating member 322 is in the first position.

[0093] In some embodiments, the stop member 324 can also not be limited to a pin shaft, and the stop member 324 can also be part of the first stop portion 3215, and only part of the area of the stop member 324 can be arranged to protrude out of the stop groove 3223 from the notch 3224 to meet the required movement stroke of the stop member 324, which is not limited in the embodiment.

[0094] Please refer to FIGS. 12-14. FIG. 12 is a partial connection structure schematic diagram of the fixed assembly 310, the rotating assembly 320, and the support assembly 330 in the unfolded state in FIG. 4. FIG. 13 is a partial connection structure schematic diagram of the fixed assembly 310, the rotating assembly 320, and the support assembly 330 in the folded state in FIG. 4. FIG. 14 is a partial enlarged schematic diagram of B in FIG. 12.

[0095] The support assembly 330 is arranged on the side of the fixing assembly 310 and the rotating assembly 320 close to the display mechanism 100, and can support the display mechanism 100 together with the aforementioned bearing surface 201. As shown in FIGS. 12 and 13, the support assembly 330 can include a middle plate 331 arranged on the fixing assembly 310, and a side plate 332 connected with the rotating assembly 320. The middle plate 331 can be arranged on the side of the base 311 away from the shielding member 313, and can surround the aforementioned first arc-shaped slot 3111 together with the base 311, so as to realize the rotating connection between the rotating member 322 and the base 311. The side plate 332 is rotatably connected with the rotating member 321 and the rotating member 322 respectively, and is rotatably connected with the fixing support 323. In the embodiment, the first stop portion 3215 and the second stop portion 3222 can be arranged on the side of the base 311 facing the middle plate 331, and the middle plate 331 can be provided with corresponding avoiding positions to avoid the first stop portion 3215 and the second stop portion 3222.

[0096] In some embodiments, the base 311 can also independently form the aforementioned first arc-shaped slot 3111, and is not limited to being arranged together with the middle plate 331 to form the aforementioned first arc-shaped slot 3111. Meanwhile, the middle plate 331 can also be a part of the fixing assembly 310, that is, the fixing assembly 310 can include the middle plate 331, and the support assembly 330 only includes the side plate 332.

[0097] Further, when the rotating member 322 is located at the first position, the middle plate 331 and the side plate 332 can be flattened to support the display mechanism 100 together with the aforementioned bearing surface 201. When the rotating member 322 is located at the second position, the side plate 332 can be driven by the rotating member 322 and the fixing support 323 to move to the side of the middle plate 331 away from the base 311. In addition, when the side plate 332 moves to the side of the middle plate 331 away from the base 311, the side of the side plate 332 away from the fixing support 323 can also intersect with the side of the middle plate 331 away from the base 311, and form an included angle less than 90°.

[0098] Further, the number of side plates 332 can be two, and the two side plates 332 can be symmetrically arranged on opposite sides of the middle plate 331 parallel to the axis Y and connected with the two rotating assemblies 320 located on opposite sides of the base 311. When the rotating member 322 is in the first position, the two side plates 332 can be flattened with the middle plate 331 to support the display mechanism 100 together with the aforementioned bearing surface 201. When the rotating member 322 is in the second position, the two side plates 332 can together with the middle plate 331 form the accommodation space 301, and the distance between the two side plates 332 increases in the direction close to the middle plate 331. In this way, the bending area of the display mechanism 100 can be accommodated by the accommodation space 301 in the shape of a water droplet, so as to reduce the probability of excessive bending of the display mechanism 100.

[0099] Further, the side plate 332 can be rotated relative to the fixed support 323 under the pushing of the cooperation part 3211 of the rotating member 321. As shown in FIG. 14, the side plate 332 can include a guide part 3321 protruding towards the rotating member 321. The cooperation part 3211 is slidingly arranged on the guide part 3321 and in point contact (high pair) with the guide part 3321, and when the cooperation part 3211 moves along the first sliding direction N on the fixed support 323 with the rotating member 321, the cooperation part 3211 slides on the guide part 3321 and can push the guide part 3321 to move, so as to drive the side plate 332 to rotate on the fixed support 323. In this embodiment, the point contact can also be understood as a line contact composed of countless contact points, and only the motion pair of the guide part 3321 and the cooperation part 3211 needs to be a high pair.

[0100] For example, the guide part 3321 has an inner side surface 3321a facing the side plate 332 and an outer side surface 3321b facing away from the side plate 332, and the inner side surface 3321a and the outer side surface 3321b can be parallel or coincident. The cooperation part 3211 has a first cooperation part 3211a slidingly arranged on the inner side surface 3321a and a second cooperation part 3211b slidingly arranged on the outer side surface 3321b, and the first cooperation part 3211a and the second cooperation part 3211b are in point contact with the inner side surface 3321a and the outer side surface 3321b, respectively. When the first cooperation part 3211a slides in the first sliding direction N with the rotating member 321, the first cooperation part 3211a can abut against the inner side surface 3321a to push the guide part 3321 to move through the inner side surface 3321a, thereby driving the side plate 332 to rotate on the fixed support 323. When the second cooperation part 3211b slides in the first sliding direction N in the opposite direction with the rotating member 321, the second cooperation part 3211b can abut against the outer side surface 3321b to push the guide part 3321 to move in the opposite direction through the outer side surface 3321b, thereby driving the side plate 332 to rotate in the opposite direction on the fixed support 323.

[0101] Further, the inner side surface 3321a and the outer side surface 3321b can be parallel or coincident curved surfaces, and the inner side surface 3321a and the outer side surface 3321b can also be staggered in the direction in which the guide portion 3321 approaches the side plate 332, that is, the inner side surface 3321a and the outer side surface 3321b do not have an overlapping area in the direction in which the guide portion 3321 approaches the side plate 332, which helps to reduce the stacking height of the guide portion 3321 and the cooperating portion 3211.

[0102] Further, in order to achieve the point contact (line contact) between the first cooperating portion 3211a and the inner side surface 3321a, the part of the first cooperating portion 3211a that is in contact with the inner side surface 3321a can be designed with a chamfer or a fillet, so as to maintain the point contact (line contact) with the inner side surface 3321a by means of the chamfer or the fillet, and the point contact (line contact) between the second cooperating portion 3211b and the outer side surface 3321b is the same. By such an arrangement, compared with the solution in which the first cooperating portion 3211a and the second cooperating portion 3211b are arranged as a pin shaft in rolling contact with the guide portion 3321, the design of the chamfer or the fillet on the first cooperating portion 3211a and the second cooperating portion 3211b causes less restriction on the shape of the first cooperating portion 3211a and the second cooperating portion 3211b, so that the first cooperating portion 3211a and the second cooperating portion 3211b can be designed as a shape with higher structural strength (such as the plate shape shown in FIG. 14), so as to enhance the motion reliability of the cooperating portion 3211 and the guide portion 3321.

[0103] Please refer to FIGS. 15 and 16, FIG. 15 is a partial cross-sectional structural schematic view of the fixed assembly 310, the rotating assembly 320 and the supporting assembly 330 along VI-VI in FIG. 12, and FIG. 16 is a partial cross-sectional structural schematic view of the fixed assembly 310, the rotating assembly 320 and the supporting assembly 330 along VI-VI in FIG. 13.

[0104] Further, the side plate 332 can also be provided with a protruding portion 3323 in rolling connection with the rotating member 322. As shown in FIGS. 15-16, the protruding portion 3323 is provided on the side plate 332 and protrudes from the side of the rotating member 322 away from the rotating member 321, and the protruding portion 3323 can be in rolling connection with the rotating member 322 and can be driven by the rotating member 322 to rotate the side plate 332 relative to the fixed support 323. For example, the side of the protruding portion 3323 facing the rotating member 322 is provided with a limiting slot 33231, and the rotating member 322 is provided with a limiting portion 3225 protruding into the limiting slot 33231. When the fixed support 323 slides relative to the rotating member 322, the side plate 332 can slide with the fixed support 323 relative to the rotating member 322, and the limiting portion 3225 can abut against the slot wall of the limiting slot 33231 to limit the side plate 332 by the protruding portion 3323, so that the portion of the side plate 332 with the protruding portion 3323 cannot slide with the fixed support 323 relative to the rotating member 322. At the same time, since the side plate 322 is also in rotational connection with the fixed support 323, when the limiting portion 3225 limits the sliding of the side plate 332 by the protruding portion 3323, the portion of the side plate 332 in rotational connection with the fixed support 323 can be driven by the limiting portion 3225 to rotate relative to the fixed support 323, and the limiting portion 3225 can be rolled synchronously in the limiting slot 33231. In this embodiment, the limiting portion 3225 can be a pin shaft to achieve rolling connection of the protruding portion 3323 and the rotating member 322. Of course, in addition to the pin shaft, the limiting portion 3225 can also be other structures capable of achieving rolling connection, which are not limited in this embodiment.

[0105] Further, in order to achieve rotational connection of the side plate 332 and the fixed support 323, the fixed support 323 can be provided with a third arc-shaped slot 3233, and the side plate 332 can have an arc-shaped portion 3324 provided in the third arc-shaped slot 3233 and capable of sliding in the third arc-shaped slot 3233. When the side plate 332 moves by the guiding portion 3321 and / or the protruding portion 3323, the arc-shaped portion 3324 can cooperate with the third arc-shaped slot 3233 to guide the movement of the side plate 332, so that the side plate 332 can rotate relative to the fixed support 323. In this embodiment, the rotation axis direction of the side plate 332 on the fixed support 323 is parallel to the rotation axis direction X of the rotating member 321.

[0106] In some embodiments, in addition to the cooperation of the arc-shaped portion 3324 and the third arc-shaped slot 3233 to achieve rotational connection, the side plate 332 can also be rotatably connected to the fixed support 323 in other ways. For example, the fixed support 323 can be provided with the same shaft-penetrating structure as the rotation shaft 312, and a portion of the side plate 332 can be sleeved on the shaft-penetrating structure and rotatably connected to the fixed support 323 by the shaft-penetrating structure.

[0107] Please refer to FIGS. 17-18, FIG. 17 is another exploded structural schematic diagram of the rotating shaft mechanism 300 in FIG. 3, and FIG. 18 is a connection structural schematic diagram of the fixed assembly 310 and the rotating assembly 320 in a flattened state in FIG. 17.

[0108] Unlike the scheme in the foregoing embodiments that three rotating assemblies 320 are arranged on each of the opposite sides of the fixed assembly 310 parallel to the axis Y, the present embodiment also provides another rotating assembly 320, which can play a role in simplifying the structure of the rotating shaft mechanism 300, so as to reduce the management difficulty of the rotating shaft mechanism 300 in the assembly process, thereby improving the assembly convenience and reliability of the rotating shaft mechanism 300. As shown in FIGS. 17-18, two rotating assemblies 320 are arranged on each of the opposite sides of the fixed assembly 310 parallel to the axis Y, and the two rotating assemblies 320 on the same side of the fixed assembly 310 can be spaced apart in the direction parallel to the axis Y. For example, the two rotating assemblies 320 on the same side of the fixed assembly 310 can be located at the top and bottom of the fixed assembly 310, respectively, so that the two rotating assemblies 320 can be spaced apart to form a spacing space for wiring (such as the flexible circuit board as described above). In the present embodiment, the rotating assemblies 320 on the opposite sides of the fixed assembly 310 parallel to the axis Y can also be symmetrically arranged about the axis Y, and the two rotating assemblies 320 on the same side of the fixed assembly 310 can also be symmetrically arranged about the direction perpendicular to the axis Y.

[0109] In some embodiments, the number of rotating assemblies 320 on the opposite sides of the fixed assembly 310 parallel to the axis Y can also not be limited to two. For example, only one rotating assembly 320 can be arranged on each of the opposite sides of the fixed assembly 310 parallel to the axis Y, and the rotating assembly 320 can be located at the middle position of the fixed assembly 310. Meanwhile, the rotating assemblies 320 on the opposite sides of the fixed assembly 310 and the two rotating assemblies 320 on the same side of the fixed assembly 310 can also not be limited to symmetrically arranged, and the arrangement position and direction of the rotating assemblies 320 on the fixed assembly 310 can also be adaptively adjusted according to design requirements, which will not be enumerated one by one in the present embodiment. In addition, when the electronic device 10 is a foldable tablet computer or other device with a larger volume, the number of rotating assemblies 320 arranged on the opposite sides of the fixed assembly 310 parallel to the axis Y can also be increased accordingly, and is not limited to one or two as described above, which will not be limited in the present embodiment.

[0110] Please refer to FIGS. 19-21, FIG. 19 is a connection structural schematic diagram of part of the fixed assembly 310 and the rotating assembly 320 in a flattened state in FIG. 18, FIG. 20 is a structural schematic diagram of part of the fixed assembly 310 in FIG. 19, and FIG. 21 is a local enlarged schematic diagram at C in FIG. 19.

[0111] The connection relationship between the fixed assembly 310 and the single rotating assembly 320 will be described below. Different from the fixed assembly 310 in the foregoing embodiments, the fixed assembly 310 in the present embodiment can include the rotating shaft 312 and the decorative piece 313 (i.e., the shielding piece 313 described above), and the base 311 can be omitted. As shown in FIGS. 19 and 20, the rotating shaft 312 can be arranged on the decorative piece 313 and can be connected with the rotating piece 321 in the rotating assembly 320, and the rotating shaft 312 is arranged on the decorative piece 313 in the same direction as the base 311 in the foregoing embodiments. That is, the extension direction of the rotating shaft 312 (i.e., the rotating shaft direction X described above) is still parallel to the extension direction of the axis Y. Meanwhile, the number of the rotating shaft 312 can correspond to the number of the rotating assembly 320 to be matched with the rotating piece 321 in the rotating assembly 320. For example, the number of the rotating shaft 312 can be four, and the four rotating shafts 312 can be arranged on the decorative piece 313 corresponding to the positions of the four rotating assemblies 320 to be matched with the rotating pieces 321 in the four rotating assemblies 320.

[0112] Further, since the base 311 is omitted, the decorative piece 313 can also be connected with the rotating piece 322 in the rotating assembly 320. The part of the decorative piece 313 corresponding to the rotating piece 322 can be locally thickened and provided with the first arc-shaped slot 3111 described above to be connected with the rotating piece 322. Meanwhile, the number of the first arc-shaped slot 3111 can correspond to the number of the rotating piece 322 to be matched with the rotating piece 322 in the rotating assembly 320. For example, each rotating assembly 320 can include two rotating pieces 322, and the decorative piece 313 can be provided with eight first arc-shaped slots 3111 corresponding to the four rotating assemblies 320. In addition, in addition to the first arc-shaped slot 3111 described above, the decorative piece 313 can also be connected with the rotating piece 322 in the rotating assembly 320 through a solid shaft such as the rotating shaft 312. That is, the decorative piece 313 and the rotating piece 322 can be connected in the same or similar manner as the base 311 and the rotating piece 322 in the foregoing embodiments, which will not be described herein.

[0113] Further, considering that directly arranging the rotating shaft 312 on the decoration piece 313 will increase the difficulty of assembling the rotating shaft 312 and the rotating assembly 320 subsequently, the fixing assembly 310 can further include a first fixing piece 315 and a second fixing piece 316 arranged on the decoration piece 313. As shown in FIGS. 19-20, the first fixing piece 315 and the second fixing piece 316 are arranged opposite and spaced apart in the extension direction of the axis Y, the rotating shaft 312 can pass through the first fixing piece 315 and the second fixing piece 316, and can be fixed on the decoration piece 313 by the first fixing piece 315 and the second fixing piece 316. For example, one end of the rotating shaft 312 can pass through the first fixing piece 315, and the other opposite end can pass through the second fixing piece 316, and the opposite ends of the rotating shaft 312 can be further fixed on the first fixing piece 315 and the second fixing piece 316 by a circlip or a retaining ring and the like fastener to avoid axial displacement of the rotating shaft 312. In addition, the first fixing piece 315 and the second fixing piece 316 can be locked with the decoration piece 313 by screws to realize the detachable connection of the rotating shaft 312 and the decoration piece 313. Of course, the first fixing piece 315 and the second fixing piece 316 and the decoration piece 313 can also be assembled in other detachable or non-detachable manner, which is not limited in the embodiment.

[0114] Through the above arrangement, when assembling the fixing assembly 310 and the rotating assembly 320, the rotating shaft 312, the first fixing piece 315, the second fixing piece 316, and the structure in the rotating shaft mechanism 300 cooperating with the rotating shaft 312 can be assembled to form a module first, and then the module is fixed on the decoration piece 313 by the first fixing piece 315 and the second fixing piece 316, so that the rotating shaft 312 and the corresponding structure in the rotating shaft mechanism 300 can be assembled without being limited by the decoration piece 313, thereby reducing the assembly difficulty of the fixing assembly 310 and the rotating assembly 320, and improving the assembly convenience of the rotating shaft mechanism 300.

[0115] Further, since the first fixing piece 315 and the second fixing piece 316 not only install the corresponding structure (such as the rotating piece 321) of the rotating assembly 320, but also install the torsion assembly (see later) of the rotating shaft mechanism 300, the part of the decoration piece 313 corresponding to the first fixing piece 315 and the second fixing piece 316 needs to be designed with a corresponding installation position by slotting. However, the slotting method will thin the thickness of the decoration piece 313 in this part of the area, and reduce the rigidity of the decoration piece 313 in this part of the area, so that the probability of bending or deformation of the decoration piece 313 in this part of the area increases, which will further affect the flatness of the rotating shaft mechanism 300, resulting in the display mechanism 100 having light and shadow problems due to insufficient support (insufficient flatness) of the rotating shaft mechanism 300.

[0116] To solve the above problems, the fixing assembly 310 can further include a third fixing piece 317 arranged on the decoration piece 313, and the third fixing piece 317 can be used to reduce the probability of deformation or bending of the decoration piece 313. As shown in FIGS. 19-20, the third fixing piece 317 is located between the first fixing piece 315 and the second fixing piece 316 and is arranged in a spaced manner with the first fixing piece 315 and the second fixing piece 316, respectively. The third fixing piece 317 can also be locked on the decoration piece 313 by a screw, so as to reinforce the thinned area of the decoration piece 313 by the third fixing piece 317. Meanwhile, the rotating shaft 312 can also be arranged through the third fixing piece 317, so that the thinned area of the decoration piece 313 can also be connected with the rotating shaft 312 through the third fixing piece 317, so as to further reinforce the thinned area of the decoration piece 313 by the rotating shaft 312. In this way, the thinned area of the decoration piece 313 can be reinforced by the cooperation of the third fixing piece 317 and the rotating shaft 312, so as to reduce the probability of bending or deformation of the decoration piece 313 in the area.

[0117] As shown in FIGS. 19-20, unlike the structure of the rotating assembly 320 in the foregoing embodiments, the rotating assembly 320 in the present embodiment can include two rotating pieces 321 and two rotating pieces 322 located on the same side of the fixing assembly 310 and rotatably connected with the fixing assembly 310, and a fixed bracket 323 slidably connected with the two rotating pieces 321 and movably connected with the two rotating pieces 322, respectively, and the two rotating pieces 321 and the two rotating pieces 322 are linked with the fixed bracket 323. Among them, the rotating shaft directions of the two rotating pieces 321 coincide with each other, the rotating shaft directions of the two rotating pieces 322 also coincide with each other, and the rotating shaft directions of the rotating pieces 321 and the rotating pieces 322 are also parallel to each other. Meanwhile, the sliding directions of the two rotating pieces 321 on the fixed bracket 323 are parallel to each other, the sliding directions of the two rotating pieces 322 on the fixed bracket 323 are also parallel to each other, and the normal projections of the sliding direction of the rotating pieces 321 and the moving direction of the rotating pieces 322 in the reference plane 3001 are not parallel to each other, and the reference plane 3001 can be perpendicular to the rotating shaft direction X of the rotating pieces 321.

[0118] Further, the two rotating members 321 can be a first rotating member 321a and a second rotating member 321b respectively, and the two rotating members 322 can be a first rotating member 322a and a second rotating member 322b respectively. Wherein, the first rotating member 321a, the second rotating member 321b, the first rotating member 322a and the second rotating member 322b are located on the same side of the fixed assembly 310 parallel to the axis Y, that is, the same side of the decorative member 313 parallel to the axis Y. At the same time, the first rotating member 321a is located between the first rotating member 322a and the second rotating member 321b, and is arranged close to the first rotating member 322a. The second rotating member 321b is located between the second rotating member 322b and the first rotating member 321a, and is arranged close to the second rotating member 322b.

[0119] Further, the first rotating member 321a and the second rotating member 321b are both rotatably sleeved on the rotating shaft 312, and the rotating shaft directions of the first rotating member 321a and the second rotating member 321b can coincide (that is, the aforementioned rotating shaft direction X). At the same time, the part of the first rotating member 321a sleeved on the rotating shaft 312 is located on the side of the first fixed member 315 close to the second fixed member 316, the part of the second rotating member 321b sleeved on the rotating shaft 312 is located on the side of the second fixed member 316 close to the first fixed member 315, and the third fixed member 317 is also located between the first rotating member 321a and the second rotating member 321b. In addition, the parts of the first rotating member 321a and the second rotating member 321b away from the rotating shaft 312 can be slidably inserted on the fixed support 323, and the sliding directions of the first rotating member 321a and the second rotating member 321b on the fixed support 323 can be parallel. That is, the first rotating member 321a and the second rotating member 321b are rotatably connected with the rotating shaft 312 and slidably connected with the fixed support 323 in the same way as the rotating member 321 in the foregoing embodiment is rotatably connected with the rotating shaft 312 and slidably connected with the fixed support 323. Hereinafter, only the first rotating member 321a sliding on the fixed support 323 along the first sliding direction N will be taken as an example for description.

[0120] Further, the first rotating member 322a and the second rotating member 322b are both rotatably arranged in the first arc-shaped slot 3111, and are rotatably connected to the decorative member 313 through the virtual shaft formed by the first arc-shaped slot 3111, and the rotation shaft directions of the first rotating member 322a and the second rotating member 322b can coincide with each other. Meanwhile, the first rotating member 322a and the second rotating member 322b both have the sliding part 3221 in the foregoing embodiment, and the fixed support 323 is provided with two sliding grooves 3232 in the foregoing embodiment, and the two sliding parts 3221 can be arranged in the two sliding grooves 3232 respectively, and the sliding part 3221 can slide in a straight line or an arc line in the sliding groove 3232 (shown in FIG. 8), so as to realize the sliding connection between the first rotating member 322a, the second rotating member 322b and the fixed support 323. That is, the first rotating member 322a and the second rotating member 322b are rotatably connected to the decorative member 313 and are slidably connected to the fixed support 323 in the same way as the first rotating member 322a and the second rotating member 322b are rotatably connected to the base 311 and are slidably connected to the fixed support 323 in the foregoing embodiment.

[0121] In some embodiments, in addition to the sliding connection described above, the first rotating member 322a and the second rotating member 322b can also be rotatably connected to the fixed support 323. For example, the fixed support 323 can be provided with a connecting shaft, and the extending direction of the connecting shaft can be parallel to the rotation shaft direction (virtual shaft) of the rotating member 322 on the base 311. Part of the rotating member 322 can be sleeved on the connecting shaft and rotatably connected to the fixed support 323 through the connecting shaft. In this way, the fixed support 323 can still be rotated relative to the rotating member 322 under the driving of the first housing assembly 210, so that the first housing assembly 210 and the second housing assembly 220 can be rotated to adjust the position of the rotating member 322, so as to ensure that the first housing assembly 210 and the second housing assembly 220 can be combined without gap when being folded. Hereinafter, only the scheme that the first rotating member 322a slides on the fixed support 323 along the second sliding direction M will be described.

[0122] In some embodiments, the rotating assembly 320 provided by the present embodiment can also be used in the fixed assembly 310 in the foregoing embodiment. That is, when the fixed assembly 310 is the scheme including the base 311, the rotation shaft 312 and the decorative member 313, the rotating assembly 320 can also include two rotating members 321, two rotating members 322 and a fixed support 323, and the cooperation mode of the fixed assembly 310 and the rotating assembly 320 can be the same as or similar to that in the foregoing embodiment, which will not be described herein.

[0123] The rotating assembly 320 provided by the embodiment comprises: the first rotating piece 321a and the second rotating piece 321b, the first rotating piece 321a and the second rotating piece 321b being located on the same side of the fixed assembly 310 and being rotatably connected with the fixed assembly 310, the first rotating piece 321a and the second rotating piece 321b being rotatably connected with the fixed support 323, the first rotating piece 321a and the second rotating piece 321b being movably connected with the first rotating piece 322a and the second rotating piece 322b respectively, and the first rotating piece 321a, the second rotating piece 321b, the first rotating piece 322a and the second rotating piece 322b being linked with the fixed support 323. Compared with the scheme of arranging six rotating assemblies 320 in the foregoing embodiment, the embodiment can link the structural pieces of the rotating assembly 320 by one fixed support 323, and reduce the number of the rotating assemblies 320 to be arranged to four, which helps to simplify the number of parts required to be controlled during the assembly process of the rotating shaft mechanism 300, reduces the control difficulty of the rotating shaft mechanism 300 during the assembly process, and thus improves the assembly convenience and reliability.

[0124] In order to realize the synchronous rotation of the two rotating assemblies 320 located on the opposite sides of the fixed assembly 310 parallel to the axis Y, the first rotating piece 321a of the two rotating assemblies 320 and the second rotating piece 321b of the two rotating assemblies 320 are provided with the foregoing synchronous assembly 340, and the synchronous assembly 340 is used to link the first rotating piece 321a of the two rotating assemblies 320 and the second rotating piece 321b of the two rotating assemblies 320, so that the two rotating assemblies 320 located on the opposite sides of the fixed assembly 310 can be synchronously rotated, and the consistency of the rotation of the two rotating assemblies 320 is improved. As shown in FIG. 19, the synchronous assembly 340 can still comprise two meshing synchronous gears 341, which is the same as the foregoing embodiment. Among them, the two synchronous gears 341 of one synchronous assembly 340 are respectively meshed with the first rotating piece 321a of the two rotating assemblies 320, and the two synchronous gears 341 of the other synchronous assembly 340 are respectively meshed with the second rotating piece 321b of the two rotating assemblies 320, so that the first rotating piece 321a in the two rotating assemblies 320 and the second rotating piece 321b in the two rotating assemblies 320 can be linked.

[0125] In order to improve the anti-drop impact performance of the rotating shaft mechanism 300, the rotating assembly 320 can further include a support member 325. As shown in FIGS. 19-21, the support member 325 is located between the first rotating member 321a and the second rotating member 321b, and the support member 325 can also be rotatably sleeved on the rotating shaft 312, so that the rotating shaft direction of the support member 325 can coincide with the rotating shaft direction of the first rotating member 321a. Meanwhile, the support member 325 can also be in sliding connection with the fixed support 323 (in the same or similar manner as the sliding connection between the rotating member 321 and the fixed support 323), and the sliding direction of the support member 325 on the fixed support 323 is also parallel to the sliding direction of the first rotating member 321a on the fixed support 323, i.e., the first sliding direction N. In this way, the support member 325 can be added between the first rotating member 321a and the second rotating member 321b to cooperate with the fixed support 323, so as to support the fixed support 323 together with the first rotating member 321a and the second rotating member 321b when the fixed support 323 moves in the thickness direction Z (intersecting the first sliding direction N) under impact, thereby enhancing the anti-drop impact performance of the rotating shaft mechanism 300.

[0126] Further, when the fixed support 323 drives the first rotating member 321a, the second rotating member 321b, and the support member 325 to rotate around the fixed assembly 310 under the action of an external force (user swinging the shell assembly), the fixed support 323 drives the first rotating member 321a, the second rotating member 321b, and the support member 325 to rotate around the fixed assembly 310 and slide relative to the first rotating member 321a, the second rotating member 321b, and the support member 325 along the first sliding direction N, and to move (slide or rotate) relative to the first rotating member 322a and the second rotating member 322b along the second sliding direction M under the action of the external force.

[0127] In some embodiments, since the support member 325 is linked with the first rotating member 321a and the second rotating member 321b through the fixed support 323, the aforementioned synchronization assembly 340 can also be provided between the support members 325 of the two rotating assemblies 320, so as to link the support members 325 of the two rotating assemblies 320 by the synchronization assembly 340, thereby realizing the synchronous rotation of the fixed assembly 310 between the two rotating assemblies 320 parallel to the axis Y.

[0128] Further, the number of the support members 325 can also be two, and respectively a first support member 325a and a second support member 325b. The first support member 325a and the second support member 325b can be adjacently arranged, and the first support member 325a is located between the second support member 325b and the first rotating member 321a, and the second support member 325b is located between the first support member 325a and the second rotating member 321b. Meanwhile, the part of the first support member 325a sleeved on the rotating shaft 312 is located on the side of the third fixed member 317 close to the first fixed member 315, and the part of the second support member 325b sleeved on the rotating shaft 312 is located on the side of the third fixed member 317 close to the second fixed member 316.

[0129] Further, the side of the first support member 325a and the second support member 325b away from each other can be slidably connected with the fixed support 323 in the first sliding direction N. As shown in FIG. 21, the fixed support 323 can be provided with an avoiding groove 3234 accommodating the first support member 325a and the second support member 325b, and the part of the first support member 325a and the second support member 325b away from the rotating shaft 312 is slidably arranged in the avoiding groove 3234. The side of the first support member 325a away from the second support member 325b is further provided with a first sliding block 325a1 located in the avoiding groove 3234, and the groove wall of the avoiding groove 3234 opposite to the first support member 325a is provided with a first groove 32341, and the first sliding block 325a1 is slidably arranged in the first groove 32341, so as to realize the sliding connection between the first support member 325a and the fixed support 323 in the first sliding direction N. Similarly, the side of the second support member 325b away from the first support member 325a is provided with a second sliding block 325b1 located in the avoiding groove 3234, and the groove wall of the avoiding groove 3234 opposite to the second support member 325b is provided with a second groove 32342, and the second sliding block 325b1 is slidably arranged in the second groove 32342, so as to realize the sliding connection between the second support member 325b and the fixed support 323 in the first sliding direction N.

[0130] Through the above arrangement, the first support member 325a and the second support member 325b can only have single-side sliding cooperation with the fixed support 323, compared with the scheme that the first support member 325a and the second support member 325b have double-side sliding cooperation with the fixed support 323, the first support member 325a and the second support member 325b can be arranged in the same avoiding groove 3234, so as to reduce the space occupied by the first support member 325a and the second support member 325b on the fixed support 323, thereby reducing the length of the fixed support 323 in the extension direction of the axis Y.

[0131] In order to provide the user with a damping rotation feeling, the rotating shaft mechanism 300 can further include a first torsion assembly 350 and a second torsion assembly 360 arranged on the fixed assembly 310. As shown in FIG. 19, the first torsion assembly 350 is arranged between the first rotating member 321a and the support member 325, and the second torsion assembly 360 is arranged between the second rotating member 321b and the support member 325. When the first rotating member 321a, the second rotating member 321b, and the support member 325 rotate around the fixed assembly 310 driven by the fixed support 323, the first torsion assembly 350 can abut against the first rotating member 321a and the support member 325, respectively, and the second torsion assembly 360 can abut against the second rotating member 321b and the support member 325, respectively. In this way, the first torsion assembly 350 and the second torsion assembly 360 can bring the user a damping rotation feeling by using the abutting force when the electronic device 10 is folded or unfolded.

[0132] In some embodiments, when the support member 325 is omitted, the first torsion assembly 350 can be arranged on the side of the first rotating member 321a away from the first rotating member 322a, and the second torsion assembly 360 can be arranged on the side of the second rotating member 321b away from the second rotating member 322b. When the first rotating member 321a and the second rotating member 321b rotate around the fixed assembly 310 driven by the fixed support 323, the first torsion assembly 350 can abut against the first rotating member 321a, and the second torsion assembly 360 can abut against the second rotating member 321b, so as to bring the user a damping rotation feeling by using the abutting force.

[0133] Further, the first torsion assembly 350 can be arranged between the first rotating member 321a and the first support member 325a, and when the first rotating member 321a and the first support member 325a rotate around the fixed assembly 310 driven by the fixed support 323, the first torsion assembly 350 can abut against the first rotating member 321a and the first support member 325a, respectively.

[0134] Further, when the first rotating member 321a and the first supporting member 325a rotate around the fixed assembly 310, the first cam 351 and the second cam 352 can be displaced in the direction of approaching each other by the pushing of the first rotating member 321a and the first supporting member 325a respectively, and jointly push the first elastic member 353 to elastically deform, so as to tightly press the first cam 351 and the second cam 352 on the first rotating member 321a and the first supporting member 325a respectively by the elastic force provided by the first elastic member 353. In this way, not only the damping rotating feeling can be provided, but also the rotation suspension of the electronic device 10 at different angles can be realized by the teeth formed by the engagement of the first cam 351 and the first rotating member 321a, and the teeth formed by the engagement of the second cam 352 and the first supporting member 325a.

[0135] Further, in order to guide the displacement of the first cam 351 and the second cam 352, the first cam 351 and the second cam 352 can also be sleeved on the rotating shaft 312 in a sliding manner, so that the first cam 351 and the second cam 352 can be displaced in the direction of approaching each other along the rotating shaft 312 when being pushed. Meanwhile, the first elastic member 353 can be a spring and can be sleeved on the rotating shaft 312, so as to guide the elastic deformation of the first elastic member 353 by the rotating shaft 312, so as to avoid the deviation of the elastic force direction of the first elastic member 353. In this embodiment, in order to enhance the damping feeling of the user when folding or unfolding the electronic device 10, the first elastic member 353 can be in the deformed state of being pushed by the first cam 351 and the second cam 352 all the time, and is not limited to being deformed when the first rotating member 321a and the first supporting member 325a rotate.

[0138] Further, when the second rotating member 321b and the second support member 325b rotate about the fixed assembly 310, the third cam 361 and the fourth cam 362 can be displaced in the direction of approaching each other respectively by the second support member 325b and the second rotating member 321b, and abut against the second elastic member 363 to cause elastic deformation of the second elastic member 363, so as to abut against the second support member 325b and the second rotating member 321b respectively by the elastic force provided by the second elastic member 363. In this way, not only can a damping rotating feeling be provided, but also the teeth formed by the engagement of the third cam 361 and the second support member 325b and the teeth formed by the engagement of the fourth cam 362 and the second rotating member 321b can be used to realize the rotating suspension of the electronic device 10 at different angles.

[0139] Further, in order to guide the displacement of the third cam 361 and the fourth cam 362, the third cam 361 and the fourth cam 362 can be sleeved on the rotating shaft 312 in a sliding manner, so that the third cam 361 and the fourth cam 362 can be displaced in the direction of approaching each other along the rotating shaft 312 when being abutted. Meanwhile, the second elastic member 363 can also be a spring and can be sleeved on the rotating shaft 312, so as to guide the elastic deformation of the second elastic member 363 by the rotating shaft 312, to avoid the direction of the elastic force of the second elastic member 363 from deviating. In this embodiment, in order to enhance the damping feeling of the user when folding or unfolding the electronic device 10, the second elastic member 363 can be in a deformed state abutted by the third cam 361 and the fourth cam 362 all the time, and is not limited to being deformed when the second rotating member 321b and the second support member 325b rotate.

[0140] In some embodiments, the third cam 361 and the fourth cam 362 can also not be limited to being sleeved on the rotating shaft 312, and other guide rods parallel to the rotating shaft 312 can also be arranged on the decorative piece 313 to guide the displacement of the third cam 361 and the fourth cam 362 and the elastic force direction of the second elastic member 363. The present embodiment is not limited in this regard.
