Description

Technical Field

[0001] This invention relates to the field of flexible screen support, and more particularly to a rotating shaft device for supporting a flexible screen and an electronic device equipped with the rotating shaft device. Background Technology

[0002] With the development of display devices, flexible foldable displays have emerged. Currently, the folding schemes for flexible foldable displays include inward folding and outward folding, and foldable screens are becoming increasingly popular. Foldable screens in related technologies generally use hinge mechanisms for support; however, most current hinge structures include many components, are complex, and are relatively wide, occupying a lot of space, which is not conducive to miniaturization. Summary of the Invention

[0003] This application provides a rotating shaft device, a folding housing provided with the rotating shaft device, and an electronic device provided with the folding housing.

[0004] This application provides a rotating shaft device, which includes a support mechanism, a first rotating assembly, and a driven assembly. The support mechanism includes two side support members. The first rotating assembly includes a positioning seat and rotating mechanisms disposed on opposite sides of the positioning seat. The rotating mechanism includes a first rotating member, a second rotating member, and a connecting member. One end of the first rotating member is rotatably connected to the positioning seat, and the other end of the first rotating member away from the positioning seat is rotatably connected to the connecting member. One end of the second rotating member is rotatably connected to the positioning seat, and the other end of the second rotating member away from the positioning seat is rotatably connected to the connecting member. A first rotation axis between the first rotating member and the connecting member is parallel to a second rotation axis between the second rotating member and the connecting member. The driven assembly includes rotating components rotatably connected to the positioning seat and the first rotating member. Two driven members on opposite sides of the positioning seat are slidably connected to corresponding side supports at the ends of the driven members away from the positioning seat. The side supports are rotatably connected to the connecting members. When the two connecting members approach each other, the first and second rotating members rotate relative to the positioning seat and the connecting members, and the two driven members rotate relative to the positioning seat and slide relative to the side supports, causing the two driven members to approach each other and fold the two side supports together. When the two connecting members move away from each other, the first and second rotating members rotate relative to the positioning seat and the connecting members, and the two driven members rotate relative to the positioning seat and slide relative to the side supports, causing the two driven members to move away from each other and unfold the two side supports together.

[0005] This application also provides an electronic device, which includes a pivot device, two frames, and a flexible screen. The pivot device is located between the two frames, and the two frames are respectively connected to connecting members of a rotating mechanism on opposite sides of the pivot device. Two side supports of the pivot device support the back of the flexible screen. When the two frames approach each other, the first rotating member and the second rotating member rotate relative to the positioning seat and the connecting member, and the two driven members rotate relative to the positioning seat and slide relative to the side supports to approach each other, so that the two side supports fold together and the flexible screen is folded. When the two frames move away from each other, the first rotating member and the second rotating member rotate relative to the positioning seat and the connecting member, and the two driven members rotate relative to the positioning seat and slide relative to the side supports to move away from each other, so that the two side supports unfold together and the flexible screen unfolds.

[0006] The hinge device of the present invention can achieve folding or flattening through a support mechanism, a first rotating component and a driven component. Compared with the prior art that supports the flexible screen through a hinge mechanism, the hinge device of the present application has a simple structure, smaller components and lower manufacturing cost. Secondly, the overall width of the hinge device of the present application is narrower, thereby reducing the internal space occupied by the hinge device in the housing, which is beneficial to the layout of other components such as the motherboard or battery.

[0038] Please refer to the following: Figures 1 to 8The electronic device 100 in the first embodiment of the present invention includes a foldable housing 20 and a flexible screen 30 disposed on the foldable housing 20. The flexible screen 30 can be a flexible display screen, a flexible touch screen, a flexible touch display screen, or other flexible components with corresponding functions, or a flexible component fixedly attached to a flexible support plate, such as a flexible display screen or a flexible touch screen attached to a flexible steel plate. The flexible screen 30 folds or unfolds with the foldable housing 20. The foldable housing 20 includes two frames 21 and a pivot device 22 connecting the two frames 21. The two frames 21 can fold or unfold with the pivot device 22. The flexible screen 30 includes a foldable area 31 corresponding to the pivot device 22, and two non-foldable areas 33 connected to opposite sides of the foldable area 31. The two non-foldable areas 33 of the flexible screen 30 can be fixed to the front of the two frames 21 respectively, and the foldable area 31 is attached to the front of the pivot device 22. The foldable area 31 of the flexible screen 30 can fold or unfold with the pivot device 22. The rotating shaft device 22 includes a support mechanism 23, a first rotating assembly 25, and a driven assembly 26, with the driven assembly 26 connected to the first rotating assembly 25. The support mechanism 23 includes two side support members 233 located on opposite sides of the front of the first rotating assembly 25, which can be folded or flattened. The first rotating assembly 25 includes a positioning seat 251 and rotating mechanisms 253 located on opposite sides of the positioning seat 251. The two side support members 233 are located on opposite sides of the positioning seat 251 and are respectively connected to the two rotating mechanisms 253. When the two side support members 233 are flattened, their front surfaces are coplanar with the front surface of the positioning seat 251, allowing the flexible screen 30 to fit against the front surfaces of the positioning seat 251 and the side support members 233. The rotating mechanism 253 includes a first rotating member 254, a second rotating member 255, and a connecting member 256. One end of the first rotating member 254 is rotatably connected to the positioning seat 251, and the other end of the first rotating member 254 away from the positioning seat 251 is rotatably connected to the connecting member 256. One end of the second rotating member 255 is rotatably connected to the positioning seat 251, and the other end of the second rotating member 255 away from the positioning seat 251 is rotatably connected to the connecting member 256. The first rotation axis C1 between the first rotating member 254 and the connecting member 256 is parallel to the second rotation axis C2 between the second rotating member 255 and the connecting member 256; that is, the first rotation axis C1 and the second rotation axis C2 are misaligned and do not coincide. The driven component 26 includes two rotating shafts 2625 rotatably connected to opposite sides of the positioning seat 251 and two driven members 262. The driven members 262 are rotatably connected to the positioning seat 251 through the rotating shafts 2625, and the end of each driven member 262 away from the positioning seat 251 is slidably connected to the corresponding side support member 233.Specifically, one end of each follower 262 is rotatably connected to the positioning seat 251, and the follower 262 is slidably connected to the side support 233; the side support 233 is rotatably connected to the corresponding connector 256, and the connector 256 rotates relative to the positioning seat 251 to drive the first rotating member 254, the second rotating member 255 and the follower 262 to rotate, and the first rotating member 254, the second rotating member 255 and the follower 262 rotate to drive the two side support members 233 to fold or unfold with each other. Specifically, when the two frames 21 fold together so that the two connectors 256 come closer together, the first rotating member 254 and the second rotating member 255 rotate relative to the positioning seat 251 and the connector 256 respectively. One end of the two driven members 262 rotates relative to the positioning seat 251 and the other end of the driven members 262 slides relative to the opposite side support member 233, causing the two driven members 262 to come closer together, so that the two side support members 233 fold together to drive the flexible screen 30 to fold together. When the two connectors 256 move away from each other, the first rotating member 254 and the second rotating member 255 rotate relative to the positioning seat 251 and the connector 256 respectively. One end of the two driven members 262 rotates relative to the positioning seat 251 and the other end of the driven members 262 slides relative to the side support member 233, causing the two driven members 262 to move away from each other, so that the two side support members 233 unfold together to drive the flexible screen 30 to unfold together.

[0039] In some embodiments, the support mechanism 23 further includes a central support member disposed between the two side supports 233. When the support mechanism 23 is in a flattened state, the front surfaces of the two side supports 233 and the central support member are coplanar, and the foldable area 31 of the flexible screen 30 fits against the front surfaces of the central support member and the side supports 233. When the support mechanism 23 is in a folded state, the front surfaces of the two side supports 233 and the central support member form a space with a teardrop or U-shaped cross-section.

[0040] The two frames 21 of the electronic device 100 are respectively connected to the two connectors 256 of the rotating shaft device 22. The frames 21 drive the first rotating member 254, the second rotating member 255, and the driven member 262 to rotate relative to the positioning seat 251 through the connectors 256, so that the two side support members 233 can be folded or unfolded with the rotating mechanism 253 and the driven member 262. The flexible screen 30 is folded or flattened with the support mechanism 23. The foldable area 31 can be bent into a U-shape, a teardrop shape, or other shapes. In this embodiment, the foldable area 31 can be bent into a teardrop shape.

[0041] In this embodiment, the front side refers to the side facing the same direction as the light-emitting surface of the flexible screen 30, and the back side refers to the side facing away from the light-emitting surface of the flexible screen 30. The electronic device 100 is, for example, but not limited to, mobile phones, tablets, monitors, LCD panels, OLED panels, televisions, smartwatches, VR headsets, automotive displays, and any other products and components with display functions. In the description of this embodiment, "connection" includes both direct and indirect connections. For example, a connection between A and B includes a direct connection between A and B or a connection through a third element C or more other elements. Connections also include integrated connections and non-integrated connections. An integrated connection means that A and B are formed and connected as a single unit, while a non-integrated connection means that A and B are not formed and connected as a single unit.

[0042] The rotating shaft device 22 of the electronic device 100 of the present invention includes a support mechanism 23, a first rotating assembly 25 and a driven assembly 26. One end of the first rotating member 254 of the first rotating assembly 25 is rotatably connected to the positioning seat 251, and the other end of the first rotating member 254 away from the positioning seat 251 is rotatably connected to the connecting member 256. One end of the second rotating member 255 is rotatably connected to the positioning seat 251, and the other end of the second rotating member 255 away from the positioning seat 251 is rotatably connected to the connecting member 256. The end of the driven member 262 away from the positioning seat 251 is slidably connected to the corresponding side support member 233. During the process of the two frames 21 folding and moving closer to each other or unfolding and moving away from each other, the connector 256 drives the first rotating member 254, the second rotating member 255 and the auxiliary member 264 to rotate relative to the positioning seat 251. The rotation of the first rotating member 254, the second rotating member 255 and the auxiliary member 264 drives the two side support members 233 to fold or unfold with each other, thereby realizing the folding or unfolding of the flexible screen 30. First, since the first rotation axis C1 between the first rotating member 254 and the connecting member 256 is parallel and spaced apart from the second rotation axis C2 between the second rotating member 255 and the connecting member 256, that is, the first rotation axis C1 and the second rotation axis C2 are parallel but misaligned, that is, the first rotation axis C1 and the second rotation axis C2 are parallel but do not coincide. Moreover, one end of the auxiliary member 264 is rotatably connected to the positioning seat 251, and the other end of the auxiliary member 264 is slidably connected to the side support member 233, so that the various components of the rotating shaft device 22 are compactly connected and the overall width of the rotating shaft device 22 is small, thereby reducing the internal space occupied by the rotating shaft device 22 in the folding shell 20. This is not only beneficial to the layout of other components such as the motherboard or battery, but also beneficial to the miniaturization development. Second, compared with the prior art that supports the flexible screen through a hinge mechanism, the rotating shaft device 22 of this application has a simple structure, lower manufacturing cost, and high reliability of the connection between the various components, thus improving the overall strength of the device.

[0043] The rotating shaft device 22 in this embodiment includes a first rotating component 25 and a driven component 26; the first rotating component 25 and the driven component 26 constitute an integral structure, which is disposed on the back of the support mechanism 23.

[0044] In some embodiments, the rotating shaft device 22 may also include two first rotating components 25 and two driven components 26. The two first rotating components 25 and the two driven components 26 respectively form two integral structures, and the two integral structures are respectively disposed at intervals on the back of the support mechanism 23. Preferably, the two integral structures are respectively disposed at opposite ends on the back of the support mechanism 23.

[0045] In some embodiments, the rotating shaft device 22 may also include only three or more first rotating components 25 and three or more driven components 26. Each first rotating component 25 and one of the driven components 26 constitute an integral structure. That is, three or more first rotating components 25 and three or more driven components 26 constitute three or more integral structures. The three or more integral structures are respectively disposed on the back side of the support mechanism 23 and are spaced apart along the length direction of the support mechanism 23.

[0046] like Figure 7 As shown, the first rotation axis C1 between the first rotating member 254 and the connecting member 256 on the same side of the positioning seat 251 is farther away from the positioning seat 251 than the second rotation axis C2 between the second rotating member 255 and the connecting member 256. That is, the first rotation axis C1 is parallel to the second rotation axis C2, and the second rotation axis C2 is closer to the positioning seat 251 than the first rotation axis C1. The parallel spacing between the first rotation axis C1 and the second rotation axis C2 in the first direction facilitates a more compact connection between the first rotating member 254, the second rotating member 255, the connecting member 256, and the positioning seat 251. The first rotation axis C1 is parallel to the rotation axis between the first rotating member 254 and the positioning seat 251, and the rotation axis between the second rotating member 255 and the positioning seat 251.

[0047] The connector 256 includes a connecting plate 2560. A first rotating member 254 and a second rotating member 255 are rotatably connected to the front side of the connecting plate 2560. The first rotation axis C1 is further away from the connecting plate 2560 than the second rotation axis C2. The first rotation axis C1 and the second rotation axis C2 are parallel and spaced apart in a second direction, which facilitates a more compact connection between the first rotating member 254, the second rotating member 255, the connector 256, and the positioning seat 251. The first direction is perpendicular to the second direction, which is parallel to the width direction of the rotating shaft device 22, and the second direction is parallel to the thickness direction of the rotating shaft device 22.

[0048] like Figures 1 to 4 As shown, the connecting parts 256 on both sides of the rotating shaft device 22 are fixedly connected to the two frames 21 respectively. When one frame 21 is folded or unfolded relative to the other frame 21, it can drive the corresponding rotating mechanism 253 and the driven part 262 to rotate relative to the positioning seat 251 to fold or unfold. The rotation of the rotating mechanism 253 and the driven part 262 drives the two side support parts 233 to rotate and slide relative to the positioning seat 251 until the two side support parts 233 are folded into a teardrop shape or unfolded into a horizontal shape. The foldable area 31 of the flexible screen 30 is folded into a teardrop shape or unfolded into a horizontal shape along with the foldable area 31.

[0049] like Figures 2-4 As shown, the frame 21 includes a front face 211, a back face 213, two opposite sides 214, and two end faces 215. A pivot device 22 connects the two adjacent end faces 215 of the two frames 21. The foldable area 31 of the flexible screen 30 is attached to the front face of the pivot device 22, and the non-foldable area 33 of the flexible screen 30 is connected to the front face 211 of the frame 21. Each frame 21 has a receiving groove 216 on its end face 215 facing the pivot device 22. The receiving groove 216 passes through the front face 211 of the frame 21, and its opposite ends extend to the opposite sides 214 of the frame 21. The opposite sides of the pivot device 22 are respectively accommodated in the receiving grooves 216 of the two frames 21, and each connector 256 is fixedly connected to the corresponding frame 21. The back face 213 of the frame 21 has several receiving spaces (not shown in the figure), which are used to install electronic devices such as circuit boards and batteries.

[0050] Please refer to the following: Figures 5-8The side support member 233 is a rectangular plate. The side of the side support member 233 away from the positioning seat 251 is connected to the connector 256 through a first arc groove 2334 and a first arc rail 2562. The axis of the first arc groove 2334 is collinear with the axis of rotation between the side support member 233 and the connector 256. The first arc groove 2334 is provided on one of the side support member 233 and the connector 256, and the first arc rail 2562 is provided on the other of the connector 256 and the side support member 233. In this embodiment, the side support member 233 includes a rectangular side support plate 2330, and the connector 256 is rotatably connected to the side support plate 2330.

The side support member 233 is provided with a guide slider 2333, and the guide slider 2333 is provided with a first arc groove 2334. The connecting member 256 is provided with a first arc rail 2562 that can be slidably accommodated in the first arc groove 2334. The connecting member 256 and the side support member 233 rotate relative to each other along the first arc groove 2334. Specifically, the guide slider 2333 protrudes from the side of the back side 2332 of the side support member 233 away from the positioning seat 251. The guide slider 2333 is an arc-shaped block, and the first arc groove 2334 is formed on the side of the guide slider 2333. One end of the first arc groove 2334 penetrates the surface of the guide slider 2333 away from the positioning seat 251, and the other end of the first arc groove 2334 extends to the back side 2332 of the side support plate 2330. The first arc groove 2334 bends away from the back surface 2332. Specifically, the middle part of the first arc groove 2334 bends away from the back surface 2332. The side support member 233 is provided with a guide slider 2333 at at least one end of the connector 256. The guide slider 2333 is provided with the first arc groove 2334 on the side facing the connector 256. The connector 256 is provided with a first arc rail 2562 on the end face facing the guide slider 2333. The first arc rail 2562 is slidably accommodated in the first arc groove 2334.

[0051] In some embodiments, the side support member 233 is provided with guide sliders 2333 at opposite ends of the connector 256, and the two sides facing each other of the two guide sliders 2333 are provided with first arc grooves 2334. The axis lines of the two first arc grooves 2334 are collinear, and one end of the first arc groove 2334 passes through the guide slider 2333 away from the surface of the positioning seat 251. The two opposite ends of the connector 256 are respectively provided with first arc rails 2562, and the two first arc rails 2562 are slidably accommodated in the two first arc grooves 2334.

[0052] In some embodiments, the side support member 233 is provided with guide sliders 2333 at opposite ends of the connector 256, and the two sides facing the two guide sliders 2333 are provided with first arc rails 2562, and the axis lines of the two first arc rails 2562 are collinear; the two opposite ends of the connector 256 are provided with first arc grooves 2334, and the two first arc rails 2562 are slidably accommodated in the two first arc grooves 2334.

[0053] In some embodiments, the connector 256 is provided with two or more first arc rails 2562, the axis lines of the two or more first arc rails 2562 are collinear, and the side support 233 is provided with two or more first arc grooves 2334 respectively corresponding to the two or more first arc rails 2562, and the two or more first arc rails 2562 are rotatably accommodated in the two or more first arc grooves 2334 respectively.

[0054] In some embodiments, the back of the side support member 233 is provided with two guide sliders 2333, and the two opposite sides of the two guide sliders 2333 are respectively provided with first arc grooves 2334. The axis lines of the two first arc grooves 2334 are collinear. One end of the first arc groove 2334 penetrates the surface of the guide slider 2333 away from the side support plate 2330, and the first arc groove 2334 bends away from the back side 2332. The connector 256 is provided with two first arc rails 2562 corresponding to the two first arc grooves 2334 respectively. The two first arc rails 2562 are slidably accommodated in the two first arc grooves 2334 respectively.

[0055] The driven member 262 and the side support member 233 are connected by a guide groove and a guide rail. The guide groove is provided on one of the side support member 233 and the driven member 262, and the guide rail is provided on the other of the driven member 262 and the side support member 233. In this embodiment, the side support member 233 is provided with a guide groove 2336, and the driven member 262 is provided with a guide rail 2621, which is slidably inserted through the guide groove 2336. Specifically, the back side 2332 of the side support plate 2330 is provided with a guide slide 2335, and a guide slide groove 2336 is provided in the guide slide 2335. The guide slide groove 2336 extends obliquely, and the two opposite ends of the guide slide groove 2336 respectively penetrate the surface of the guide slide 2335 facing the positioning seat 251 and the surface away from the positioning seat 251. During the folding or flattening process of the rotating mechanism 253, the guide slide rail 2621 slides through the guide slide groove 2336 of the side support member 233.

[0056] Preferably, the guide slide 2335 is a guide slide block protruding from the back surface 2332 of the side support plate 2330 near the positioning seat 251. A guide slide groove 2336 is provided on the guide slide block, extending obliquely from the side near the positioning seat 251 to the side away from the side support plate 2330 and the positioning seat 251.

The guide rail 2621 is a guide rod slidably passing through the guide slide groove 2336. During the folding or flattening process of the side support member 233 with the rotation mechanism 253, the guide rod slides within the guide slide groove 2336.

[0057] like Figure 8 As shown, the guide slide 2335 includes a first end face facing the positioning seat 251 and a second end face away from the first end face. The two opposite ends of the guide slide groove 2336 pass through the guide slide 2335 to form a first opening 2336a and a second opening 2336b. The first opening 2336a is closer to the positioning seat 251 than the second opening 2336b, and the second opening 2336b is farther away from the side support plate 2330 than the first opening 2336a.

The axis of the second connecting shaft 2502 is parallel to the axis of the third arc track 2552. Preferably, the side of the connecting portion 2553 facing away from the third arc track 2552 forms an arc surface, which is beneficial for the second rotating member 255 to rotate relative to the connecting member 256.

[0069] In some embodiments, the second connecting shaft 2502 and the second rotating member 255 are integrally formed, which facilitates processing and reduces manufacturing costs.

The arc rail is rotatably inserted into the arc groove, and the axis of rotation of the arc groove, the axis of rotation of the arc rail, and the axis of rotation between the second rotating member 255 and the positioning seat 251 are collinear.

[0073] like Figures 7-10As shown, the connector 256 is strip-shaped, and at least one end of the connecting plate 2560 is provided with a first arcuate rail 2562, which is rotatably accommodated in the first arcuate groove 2334 of the side support member 233. The surface of the connecting plate 2560 facing the side support member 233 (i.e., the front) is provided with a pair of mutually spaced first connecting portions 2564 and a pair of mutually spaced second connecting portions 2565. The connecting portion 2542 of the first rotating member 254 is rotatably connected between the pair of first connecting portions 2564, and the connecting portion 2553 of the second rotating member 255 is rotatably connected between the pair of second connecting portions 2565.

The connecting plate 2560 is provided with a clearance groove between the pair of second connecting portions 2565, the clearance groove being used to avoid obstructing the connecting portion 2553 of the second rotating member 255, so as to prevent the second rotating member 255 from being unable to rotate relative to the connecting member 256.

[0074] like Figure 7 and Figure 8 As shown, the driven member 262 and the side support member 233 are slidably connected via a guide groove 2336 and a guide rail 2621. Specifically, the driven member 262 also includes a rotating part 2622, the guide rail 2621 is connected to the rotating part 2622, and the rotating part 2622 is rotatably connected to the positioning seat 251. During the rotation of the rotating part 2622 relative to the positioning seat 251, the guide rail 2621 slides through the corresponding guide groove 2336. The driven member 262 and the positioning seat 251 are rotatably connected via a rotating shaft and a connecting hole. The rotating shaft is located on one of the driven member 262 and the positioning seat 251, and the connecting hole is located on the other of the driven member 262 and the positioning seat 251. The axis of the rotating shaft is parallel to the first rotation axis C1. In this embodiment, the rotating part 2622 has a connecting hole 2623 in a direction parallel to the first rotation axis C1, and one end face of the positioning seat 251 is provided with a rotating shaft 2625, which is rotatably inserted into the connecting hole 2623. Specifically, the rotating part 2622 is a rotating cylinder, and the connecting hole 2623 passes through the opposite two end faces of the rotating cylinder along its axial direction. One end of the rotating shaft 2625 is inserted into the connecting hole 2515 of the positioning seat 251.

[0075] The follower 262 also includes a connecting portion 2624 connecting the rotating part 2622 and the guide rail 2621. The guide rail 2621 is connected to the rotating part 2622 through the connecting portion 2624. Specifically, the connecting portion 2624 is provided on the outer peripheral wall of the rotating part 2622, and the guide rail 2621 is connected to the end of the connecting portion 2624 away from the rotating part 2622, and the guide rail 2621 extends obliquely from the connecting portion 2624 away from the rotating part 2622. In this embodiment, the guide rail 2621 is a guide rod connected to the end of the connecting portion 2624 away from the rotating part 2622, and the guide rod extends obliquely away from the rotating part 2622. Specifically, the connecting portion 2624 is a protrusion extending radially along the rotating portion 2622, and the guide rail 2621 extends obliquely from the end of the protrusion away from the rotating portion 2622 toward the side away from the rotating portion 2622 and the corresponding side support plate 2330. That is, the end of the guide rail 2621 away from the connecting portion 2624 is farther away from the side support plate 2330 than the other end close to the connecting portion 2624.

[0076] like Figures 7-9 As shown, the rotating shaft device 22 also includes a back cover 28, and a positioning seat 251 is connected to the back cover 28. Specifically, the back cover 28 is a strip frame with a receiving groove 280. The positioning seat 251 is accommodated in the receiving groove 280 and fixedly connected to the back cover 28. Preferably, the back cover 28 has a mounting portion (not shown) on the inner surface of the receiving groove 280, and the positioning seat 251 is connected to the mounting portion. The connection between the positioning seat 251 and the mounting portion can be achieved by, but is not limited to, screwing, snap-fitting, or gluing.

[0077] Please refer to the following: Figures 5-15When assembling the rotating shaft device 22, the ends of the connecting portions 2542 of the two first rotating members 254 away from the second arc rail 2541 are respectively housed between a pair of first connecting portions 2564 of the two connecting members 256, so that the two first connecting shafts 2501 are respectively inserted into the shaft holes 2544 and the corresponding first connecting holes 2503 of the two connecting portions 2542, so that the two first rotating members 254 are rotatably connected to the two connecting members 256; the ends of the connecting portions 2553 of the two second rotating members 255 away from the third arc rail 2552 are respectively housed between a pair of second connecting portions 2565 of the two connecting members 256, so that the two second connecting shafts 2502 are respectively inserted into the shaft holes 2554 and the corresponding second connecting holes 2504 of the two connecting portions 2553, so that the two second rotating members 255 are rotatably connected to the two connecting members 256. The second arc rails 2541 of the two first rotating members 254 are respectively housed in the two second arc grooves 2511 of the first seat 2510, and the third arc rails 2552 of the two second rotating members 255 are respectively housed in the two third arc grooves 2512 of the first seat 2510. Then, the second seat 2516 is placed on the first seat 2510, so that the two first arc convex surfaces 2517 of the second seat 2516 are respectively attached to the front of the two second arc rails 2541 and the two second arc convex surfaces 2518 are respectively attached to the front of the two third arc rails 2552, so that the first rotating members 254 and the second rotating members 255 are rotatably connected to the positioning seat 251.

[0078] Two rotating shafts 2625 are respectively inserted into the two connecting holes 2515 of the first base 2510, and the rotating parts 2622 of the two driven members 262 are respectively sleeved on the two rotating shafts 2625, that is, the two rotating shafts 2625 are respectively inserted into the connecting holes 2623 of the two rotating parts 2622; the two side support members 233 are respectively placed on opposite sides of the front of the first rotating assembly 25, so that the guide rails 2621 of the two driven members 262 are slidably inserted into the guide grooves 2336 of the two side support members 233, and the first arc rails 2562 of the two connecting members 256 are slidably accommodated in the first arc grooves 2334 of the two side support members 233.

[0079] The first rotating assembly 25 and the driven assembly 26 are placed in the back cover 28, and the positioning seat 251 is connected to the back cover 28. When the two side supports 233 are flattened, the front surfaces of the two side supports 233 are coplanar with the front surfaces of the positioning seat 251. The first arc rail 2562 is rotatably accommodated in the corresponding first arc groove 2334, and the guide rail 2621 is slidably inserted into the guide groove 2336. At this time, the connecting part 2624 of the driven member 262 is close to the first opening 2336a of the guide groove 2336, and the guide part 2335 abuts against the connecting part 2624 to prevent the side supports 233 from unfolding further and folding back. When the two side supports 233 are folded, the front of the two side supports 233 and the front of the positioning seat 251 together form a teardrop-shaped space. The first arc rail 2562 is rotatably accommodated in the corresponding first arc groove 2334. The guide rail 2621 is slidably inserted into the guide groove 2336, and the connecting part 2624 of the follower 262 is away from the first opening 2336a of the guide groove 2336.

[0080] like Figure 7 and Figure 16 As shown, when the rotating shaft device 22 is in a flattened state, the first distance L1 between the rotation axis C3 between the first rotating member 254 and the positioning seat 251 and the first rotation axis C1 between the first rotating member 254 and the connecting member 256 is greater than the second distance L2 between the rotation axis C4 between the second rotating member 255 and the positioning seat 251 and the second rotation axis C2 between the second rotating member 255 and the connecting member 256. The first distance L1 is the distance between the first rotation axis C1 and the rotation axis C3 along the flattening direction, and the second distance L2 is the distance between the second rotation axis C2 and the rotation axis C4 along the flattening direction. Specifically, the first rotation axis C1 is the axis of the first connecting shaft 2501, the second rotation axis C2 is the axis of the second connecting shaft 2502, the rotation axis C3 between the first rotating component 254 and the positioning seat 251 is the axis of the virtual axis, and the rotation axis C4 between the second rotating component 255 and the positioning seat 251 is the axis of the virtual axis. The first rotation axis C1, the second rotation axis C2, the rotation axis C3 and the rotation axis C4 are parallel to each other. The rotation axis C3 and the rotation axis C4 are closer to the flexible screen than the first rotation axis C1 and the second rotation axis C2. The first distance L1 between the first rotation axis C1 and the rotation axis C3 is greater than the second distance L2 between the second rotation axis C2 and the rotation axis C4. The first rotation axis C1 is closer to the flexible screen than the second rotation axis C2.

[0081] In some embodiments, the rotation axis C3 between the first rotating member 254 and the positioning seat 251 may also be collinear with the rotation axis C4 between the second rotating member 255 and the positioning seat 251.

[0082] When the connecting member 256 drives the first rotating member 254, the second rotating member 255, and the driven member 262 to rotate relative to the positioning seat 251, the rotation of the rotating mechanism 253 and the driven member 262 drives the side support member 233 to rotate and slide relative to the positioning seat 251, so that the two side support members 233 fold or unfold relative to each other. Specifically, the first rotating member 254 rotates relative to the positioning seat 251 via the second arc track 2541 and the second arc groove 2511, and the second rotating member 255 rotates relative to the positioning seat 251 via the third arc track 2552 and the third arc groove 2512, so as to drive the side support member 233 to rotate and slide relative to the positioning seat 251; the driven member 262 rotates with the side support member 233 along the corresponding rotating shaft 2625 relative to the positioning seat 251, and the guide rail 2621 is in the guide groove 23 In the sliding mechanism 36, the first arc track 2562 of the connector 256 is rotatably connected to the corresponding first arc groove 2334, the second arc track 2541 of the first rotating member 254 and the third arc track 2552 of the second rotating member 255 are rotatably connected to the positioning seat 251, and the connecting part 2542 of the first rotating member 254 and the connecting part 2553 of the second rotating member 255 are rotatably connected to the connector 256, so as to realize the mutual folding or mutual unfolding of the two side support members 233.

[0083] like Figures 18-22 When the rotating shaft device 22 is bent from its flattened state, one of the connecting members 256 is bent relative to the positioning seat 251 toward the other connecting member 256. The connecting member 256 drives the second arc track 2541 of the first rotating member 254 to rotate in the second arc groove 2511 of the positioning seat 251. The connecting member 256 drives the third arc track 2552 of the second rotating member 255 to rotate in the third arc groove 2512 of the positioning seat 251. The connecting member 256 also drives the side support member 233 to move relative to the positioning seat 251. The side support member 233 drives the driven member 262 to rotate relative to the positioning seat 251, so that the guide rail 2621 of the driven member 262 slides in the guide groove 2336, and the connecting part 2624 of the driven member 262 gradually moves away from the first opening 2336a of the guide groove 2336. At the same time, the connector 256 drives the first arc track 2562 to rotate and connect to the corresponding first arc groove 2334, so that the driven members 262 on both sides of the positioning seat 251 rotate relative to each other and move closer to each other, so as to drive the two side support members 233 to move closer to each other until the two side support members 233 and the positioning seat 251 form a teardrop shape in cross section.

[0084] like Figures 17 to 22As shown, during the folding process of the side support 233 relative to the positioning seat 251, the rotating part 2622 of the guide rail 2621 rotates relative to the positioning seat 251. At the same time, the guide rail 2621 slides in the guide groove 2336, causing the connecting part 2624 to gradually move away from the first opening 2336a of the guide groove 2336. Meanwhile, the first rotating part 254 and the second rotating part 255 on opposite sides of the positioning seat 251 move closer to each other, so that the first rotation axis C1 on opposite sides of the positioning seat 251 moves closer to each other and the second rotation axis C2 on opposite sides of the positioning seat 251 moves closer to each other, until the front of the two side support 233 and the front of the positioning seat 251 form a space with a teardrop-shaped cross-section.

[0085] In other usage scenarios, the two connecting members 256 can rotate together in opposite directions, the two first rotating members 254 can rotate relative to each other via the second arc rail 2541 and the corresponding second arc groove 2511, and the two second rotating members 255 can rotate relative to each other via the third arc rail 2552 and the corresponding third arc groove 2512, as well as the two driven members 262; they can rotate around the corresponding pivot 2625 and move closer to each other; at the same time, the two connecting members 256 synchronously drive the two first arc rails 2562 to rotate and connect to the first arc groove 2334 of the two side support members 233, and the guide rail 2621 of the driven member 262 slides in the guide groove 2336; so as to drive the two side support members 233 to move closer to each other until the two side support members 233 and the positioning seat 251 form a teardrop shape in cross section.

[0086] When the rotating shaft device 22 is flattened from its bent state, one of the connecting members 256 is unfolded relative to the positioning seat 251 away from the other connecting member 256. The connecting member 256 drives the second arc track 2541 of the first rotating member 254 to rotate in the second arc groove 2511 of the positioning seat 251. The connecting member 256 drives the third arc track 2552 of the second rotating member 255 to rotate in the third arc groove 2512 of the positioning seat 251. The connecting member 256 also drives the side support member 233 to move relative to the positioning seat 251. The side support member 233 drives the driven member 262 to rotate relative to the positioning seat 251, so that the guide rail 2621 on the driven member 262 slides in the guide groove 2336, and the connecting part 2624 of the driven member 262 gradually approaches the first opening 2336a of the guide groove 2336. At the same time, the connector 256 drives the first arc track 2562 to rotate and connect to the corresponding first arc groove 2334, so that the driven members 262 on both sides of the positioning seat 251 rotate relative to each other and unfold, thereby driving the two side support members 233 to unfold relative to each other until the two side support members 233 and the positioning seat 251 are flattened.

[0087] like Figure 7 and Figure 23 As shown, during the flattening process of the side support 233 relative to the positioning seat 251, the rotating part 2622 of the guide rail 2621 rotates relative to the positioning seat 251. At the same time, the guide rail 2621 slides in the guide groove 2336, causing the connecting part 2624 to gradually approach the first opening 2336a of the guide groove 2336. Simultaneously, the first rotating part 254 and the second rotating part 255 on opposite sides of the positioning seat 251 move closer to each other, causing the first rotation axis C1 on opposite sides of the positioning seat 251 to move away from each other and the second rotation axis C2 on opposite sides of the positioning seat 251 to move away from each other, until the two side support members 233 are successfully flattened, making the front of the two side support members 233 coplanar with the front of the positioning seat 251.

[0088] In other usage scenarios, the two connecting members 256 can be rotated together in a direction away from each other. The two first rotating members 254 are moved away from each other by rotating relative to each other through the second arc rail 2541 and the corresponding second arc groove 2511. The two second rotating members 255 are moved away from each other by rotating relative to each other through the third arc rail 2552 and the corresponding third arc groove 2512. The two driven members 262 rotate around the corresponding pivot 2625 and move away from each other. At the same time, the two connecting members 256 synchronously drive the two first arc rails 2562 to rotate and connect to the first arc groove 2334 of the two side support members 233. The guide rail 2621 on the driven member 262 slides in the guide groove 2336 of the corresponding side support member 233. This drives the two side support members 233 to move away from each other until the front of the two side support members 233 is flush with the front of the positioning seat 251.

[0089] In some embodiments, the guide rail 2621 on the driven member 262 and the guide groove 2336 on the side support member 233 are interchangeable. That is, the guide groove 2336 can be provided on the driven member 262, and the guide rail 2621 can be fixed to the side support member 233. The guide rail 2621 is slidably and rotatably inserted into the guide groove 2336. Specifically, a guide groove is provided on the side of the driven member 262 facing the guide portion 2335, and a guide rail that can be slidably inserted into the limiting groove is provided on the guide portion 2335 of the side support member 233. During the bending or unfolding process of the rotating shaft device 22, the guide rail slides in the guide groove.

[0090] Please refer to the following: Figures 1-4The installed hinge device 22 is placed between the two frames 21. The connectors 256 on opposite sides of the back cover 28 are respectively housed in the receiving slots 216 of the two frames 21, and the two connectors 256 are respectively fixedly connected to the two frames 21. At this time, the front faces 211 of the two frames 21, the front faces of the two side support members 233, and the front faces 2311 of the positioning seat 251 are coplanar. The back of the flexible screen 30 is connected to the front faces 211 of the two frames 21 and the front face of the hinge device 22; specifically, the foldable area 31 is attached to the front face of the hinge device 22, and the two non-foldable areas 33 are respectively attached to the front faces of the two frames 21. When the flexible screen 30 is in a flattened state, the front of the positioning base 251 is flush with the front of the two side supports 233. Since the front of the side supports 2331 is coplanar with the front of the positioning base 251, the flexible screen 30 is not subjected to impacts at the step difference when flattened, and the flexible screen 30 will not exhibit defects such as colored spots or bright spots, ensuring the reliability of the flexible screen 30. At the same time, it also improves the touch feel of the flexible screen 30 and enhances the user experience. Furthermore, there is communication between the driven member 262 and the side supports 233. The guide groove 2336 is connected to the guide rail 2621, the driven member 262 is rotatably connected to the positioning seat 251, and the side support member 233 and the connecting member 256 are connected through the first arc rail 2562 and the first arc groove 2334. Therefore, the connection between the components in the rotating shaft device 22 can be made more compact, thereby reducing the overall width of the rotating shaft device 22, reducing the internal space occupied by the folding housing 20, which is beneficial to the layout of other components such as the motherboard or battery, and is beneficial to the miniaturization of the electronic device 100.

[0091] Please refer to the following: Figures 11-23When bending the electronic device 100, a folding force is applied to at least one of the two frames 21 of the electronic device 100, causing the rotating mechanism 253 connected to the two frames 21 to rotate in a direction that is close to each other. The folding of the pivot device 22 is achieved through the first rotating component 25 and the follower 262, and the foldable area 31 of the flexible screen 30 bends with the pivot device 22. Specifically, when a folding force is applied to one of the frames 21, the frame 21 causes the corresponding first rotating member 254, second rotating member 255, and follower 262 to rotate relative to the positioning seat 251 toward the side closer to the flexible screen 30. Specifically, the second arc track 2541 of the first rotating member 254 rotates relative to the second arc groove 2511 of the positioning seat 251, the third arc track 2552 of the second rotating member 255 rotates relative to the third arc groove 2512 of the positioning seat 251, and the rotating part 2622 of the follower 262 rotates relative to the positioning seat 251 and the guide rail 2621 slides in the guide groove 2336. Simultaneously, the connector 256 drives the first arc track 2562 to rotate and connect to the corresponding first arc groove 2334, causing the rotating mechanisms 253 on both sides to rotate relative to each other and move closer together, and the two driven members 262 to rotate relative to each other and move closer together, so as to drive the two side support members 233 to move closer together until the two side support members 233 and the positioning seat 251 form a teardrop shape in cross section; the foldable area 31 of the flexible screen 30 bends with the rotating shaft device 22 until the front sides of the two non-foldable areas 33 of the flexible screen 30 are in contact with each other, and the foldable area 31 bends into a teardrop shape, thereby realizing the seamless folding of the electronic device 100.

[0092] During the bending process of the electronic device 100, the foldable area 31 of the flexible screen 30 is bent into a teardrop shape, reducing the duty cycle of the foldable area 31 after bending, thereby reducing the overall thickness of the electronic device 100.

[0093] In other ways of folding the electronic device 100, a folding force can be applied to both frames 21 at the same time. The two frames 21 drive the two rotating mechanisms 253 to rotate toward the side closer to the flexible screen 30, and drive the two driven members 262 to rotate toward the side closer to the flexible screen 30. The folding of the electronic device 100 is achieved through the rotating shaft device 22.

[0094] When the electronic device 100 needs to be flattened, one of the frames 21 is pulled outward, causing the two rotating mechanisms 253 connected to the two frames 21 to rotate in a direction away from each other. Specifically, an outward pulling force is applied to one of the frames 21 of the electronic device 100, causing the corresponding first rotating member 254 to rotate relative to the positioning seat 251 away from the flexible screen 30, and the corresponding second rotating member 255 to rotate relative to the positioning seat 251 away from the flexible screen 30. Additionally, one of the connecting members 256 causes the side support member 233 to move relative to the positioning seat 251, so that the side support member 233 causes the driven member 262 to rotate relative to the positioning seat 251, and the guide rail 2621 on the driven member 262 slides in the guide groove 2336. At the same time, the connector 256 drives the first arc track 2562 to rotate and connect to the corresponding first arc groove 2334, so that the driven members 262 on both sides rotate relative to each other and unfold, so as to drive the two side support members 233 to unfold relative to each other until the two side support members 233 and the positioning seat 251 are flattened, and the foldable area 31 of the flexible screen 30 unfolds with the rotating shaft device 22 until the flexible screen 30 is flattened.

[0095] In other folding methods of the electronic device 100, an outward pulling force can be applied to both frames 21 at the same time. The two frames 21 respectively drive the two rotating mechanisms 253 and the two driven members 262 to rotate relative to the side away from the flexible screen 30, and the electronic device 100 is unfolded through the rotating shaft device 22.

[0096] The rotating shaft device 22 of the electronic device 100 of the present invention achieves folding or unfolding through the first rotating component 25 and the driven component 26. Since the first rotation axis C1 between the first rotating component 254 and the connecting component 256 is parallel and misaligned with the second rotation axis C2 between the second rotating component 255 and the connecting component 256, and the driven component 262 and the side support component 233 are connected by the inclined guide groove 2336 and the guide rail 2621, the connection between the components in the rotating shaft device 22 can be made more compact, thereby reducing the overall width of the rotating shaft device 22, reducing the internal space occupied by the folding shell 20, and facilitating the layout of other components such as the motherboard or battery; secondly, the structure of the rotating shaft device 22 is robust, improving the overall strength of the electronic device 100.

[0097] Please refer to the following: Figures 24-26The structure of the rotating shaft device 22a in the second embodiment of this application is similar to that of the rotating shaft device 22 in the first embodiment, except that: the driven member 262 and the guide slide 2335 of the rotating shaft device 22a in the second embodiment can be positioned by the first positioning part and the second positioning part. When the two side support members 233 are in a flattened state, the driven member 262 is positioned on the guide slide 2335 by the first positioning part to prevent the side support members 233 from folding back and damaging the flexible screen 30; when the two side support members 233 are in a folded state, the driven member 262 is positioned on the guide slide 2335 by the second positioning part to prevent the side support members 233 from folding further and damaging the flexible screen 30. The first positioning part is provided on one of the driven member 262 and the guide slide 2335, and the second positioning part is provided on the other of the driven member 262 and the guide slide 2335.

[0098] In this embodiment, the follower 262 further includes a first positioning part 2627 and a second positioning part 2628. When the two side support members 233 are in a flat state, the follower 262 is positioned on the guide slide part 2335 through the first positioning part 2627. When the two side support members 233 are in a folded state, the follower 262 is positioned on the guide slide part 2335 through the second positioning part 2628. Specifically, the first positioning part 2627 is located at one end of the guide rail 2621 near the rotating part 2622, and the second positioning part 2628 is located at one end of the guide rail 2621 away from the rotating part 2622. When the two side support members 233 are in a flattened state, the first positioning part 2627 abuts against the surface of the guide rail 2335 facing the positioning seat 251 to prevent the side support members 233 from unfolding further and folding back. When the two side support members 233 are in a folded state, the second positioning part 2628 abuts against the surface of the guide rail 2335 facing away from the positioning seat 251 to prevent the side support members 233 from bending further.

[0099] Preferably, the first positioning part 2627 is a first protrusion protruding from the outer peripheral surface of the guide rail 2621 near the connecting part 2624, and the second positioning part 2628 is a second protrusion protruding from the outer peripheral surface of the guide rail 2621 at the end away from the connecting part 2624. When the two side support members 233 are in a flattened state, the first protrusion abuts against the surface of the guide rail 2335 facing the positioning seat 251; when the two side support members 233 are in a folded state, the second protrusion abuts against the surface of the guide rail 2335 facing away from the positioning seat 251.

[0100] During the folding process of the rotating shaft device 22 from the flattened state, the rotating parts 2622 of the two driven members 262 rotate relative to the positioning seat 251 and move closer to each other. The guide rail 2621 slides in the guide groove 2336, causing the first positioning part 2627 to gradually move away from the guide part 2335, while the second positioning part 2628 gradually moves closer to the guide part 2335, until the second positioning part 2628 abuts against the guide part 2335 and moves away from the surface of the positioning seat 251. During the flattening process of the rotating shaft device 22 from the bent state, the rotating parts 2622 of the two driven members 262 rotate relative to the positioning seat 251 and move further apart. The guide rail 2621 slides in the guide groove 2336, causing the first positioning part 2627 to gradually move closer to the guide part 2335, while the second positioning part 2628 gradually moves away from the guide part 2335, until the first positioning part 2627 abuts against the surface of the guide part 2335 facing the surface of the positioning seat 251.

[0101] Please see Figure 27 The structure of the rotating shaft device 22b in the third embodiment of this application is similar to that of the rotating shaft device 22 in the first embodiment described above. The difference is that the rotating shaft device 22b in the third embodiment further includes a linkage mechanism. The linkage mechanism includes a gear assembly 265 disposed between two driven members 262, and the two driven members 262 achieve synchronous rotation through the gear assembly 265. Specifically, the gear assembly 265 includes a first gear (not shown in the figure) disposed on the driven member 262 and at least two meshing second gears 2652, with each first gear meshing with a corresponding second gear 2652. In this embodiment, a first gear is provided on the outer peripheral wall of the rotating part 2622 of each driven member 262, and two meshing second gears 2652 are provided between the rotating parts 2622 of the two driven members 262. Each second gear 2652 meshes with the corresponding first gear. When one of the driven members 262 rotates relative to the positioning seat 251, the first gear on the one driven member 262 rotates and drives the first gear on the other driven member 262 to rotate through the two second gears 2652, so that the two driven members 262 rotate synchronously, thereby realizing the synchronous folding or synchronous unfolding of the two driven members 262, so that the two rotating mechanisms 253 fold or unfold synchronously relative to the positioning seat 251, and the two side support members 233 fold or unfold synchronously.

[0102] Since the rotating shaft device 22b in this embodiment also includes a linkage mechanism, during the folding or flattening process, the two driven members 262, the two first rotating members 254 and the two second rotating members 255 achieve synchronous folding or flattening, thereby driving the two side support members 233 to achieve synchronous folding or flattening. It is convenient to use and simple to operate.

[0103] In some embodiments, the gear combination 265 between a pair of followers 262 can be omitted, and the first gears on the rotating portions 2622 of the pair of followers 262 mesh with each other; the rotating portions 2622 of the pair of followers 262 can achieve synchronous rotation through the meshing first gears, thereby further reducing the width of the rotating shaft device 22.

[0104] In some embodiments, the gear combination between the rotating portions 2622 of a pair of followers 262 includes a plurality of meshing second gears 2652, wherein two second gears 2652 mesh with first gears on the rotating portions 2622 of a pair of followers 262 respectively; the pair of followers 262 can achieve synchronous rotation through the gear combination.

[0105] This application also provides an electronic device equipped with a pivot device 22b. The electronic device includes two frames connected to connectors 256 on opposite sides of the pivot device 22b, and a flexible screen covering the frames and the pivot device 22b. During the bending or flattening of the electronic device, two driven members 262, two first rotating members 254, and two second rotating members 255 fold or flatten synchronously, thereby driving the two side support members 233 to fold or unfold synchronously, facilitating the folding or flattening of the electronic device and simplifying operation.

[0106] In some instances, a linkage mechanism is added to the rotating shaft device 22a. This linkage mechanism includes a gear assembly 265 disposed between two driven members 262, enabling synchronous rotation of the two driven members 262. Specifically, the gear assembly 265 includes a first gear (not shown) disposed on the outer peripheral wall of the rotating part 2622 and at least two meshing second gears 2652, with each first gear meshing with a corresponding second gear 2652.

[0107] Please see Figure 28 and Figure 29The structure of the rotating shaft device 22c in the fourth embodiment of this application is similar to that of the rotating shaft device 22 in the first embodiment described above. The difference is that the first rotating member 254 and the side support member 233 of the rotating shaft device 22c in the fourth embodiment are connected by a first limiting groove and a first limiting part. The first limiting groove is provided in one of the first rotating member 254 and the side support member 233, and the first limiting part is provided in the other of the first rotating member 254 and the side support member 233. In this embodiment, a limiting block 2337 protrudes from the back surface 2332 of the side support member 233 corresponding to the first rotating member 254. The limiting block 2337 has an arc-shaped first limiting groove 2338 that penetrates the two opposite sides of the limiting block 2337 and bends and extends towards the side closer to the positioning seat 251. The surface of the first rotating member 254 facing the limiting block 2337 is provided with a first limiting part 2540, which is slidably and rotatably inserted into the first limiting groove 2338. Specifically, a connecting hole is provided on one side of the connecting part 2542 away from the second arc track 2541, and the first limiting part 2540 is connected to the connecting hole. In this embodiment, a connecting cylinder protrudes from one side of the connecting part 2542 away from the second arc track 2541, and the first limiting part 2540 is connected to the inner cavity of the connecting cylinder; further, the first limiting part 2540 is a first limiting shaft inserted and fixed in the inner cavity of the connecting cylinder, and the axis of the first limiting shaft is parallel to the axis of the second arc track 2541. One end of the first limiting part 2540 is fixedly connected to the connecting part 2542, and the other end of the first limiting part 2540 is used to slide and rotatably pass through the first limiting groove 2338 of the side support member 233. In some embodiments, the first limiting portion 2540 may also be integrally formed with the first rotating member 254. During the folding or flattening process, the first limiting portion 2540 slides and rotates along the first limiting groove 2338.

[0108] Preferably, the first limiting groove 2338 is an arc-shaped groove, comprising a first limiting segment 2338a and a second limiting segment 2338b located at opposite ends. The first limiting segment 2338a is closer to the positioning seat 251 than the second limiting segment 2338b. The first limiting shaft is located at the end of the first rotating member 254 away from the positioning seat 251, and the axis of the first limiting shaft is parallel to the first rotation axis C1. When the two side supports 233 are in a flattened state, the first limiting shaft is positioned at the second limiting segment 2338b to prevent the side supports 233 from folding back and damaging the flexible screen 30. When the two side supports 233 are in a fully folded state, the first limiting shaft is positioned at the first limiting segment 2338a to prevent the side supports 233 from folding further and damaging the flexible screen 30. During the bending process of the rotating shaft device 22c, the first limiting part 2540 on the first rotating member 254 slides and rotates in the first limiting groove 2338, and the first limiting part 2540 moves from the second limiting segment 2338b to the first limiting segment 2338a; during the flattening process of the rotating shaft device 22c, the first limiting part 2540 on the first rotating member 254 slides and rotates in the first limiting groove 2338, and the first limiting part 2540 moves from the first limiting segment 2338a to the second limiting segment 2338b.

[0109] In some embodiments, the first limiting portion 2540 on the first rotating member 254 and the first limiting groove 2338 on the side support member 233 can be interchanged. Specifically, the first limiting groove is provided on the side of the first rotating member 254 facing the limiting block 2337, and the first limiting shaft is provided on the limiting block 2337 of the side support member 233, which can be movably inserted into the first limiting groove. During the bending or unfolding process of the rotating shaft device 22c, the first limiting shaft slides and rotates in the first limiting groove.

[0110] This application also provides an electronic device equipped with a pivot device 22c, the electronic device including two frames connected to connectors 256 on opposite sides of the pivot device 22c and a flexible screen 30 covering the frames and the pivot device 22c.

[0111] Please see Figure 30 and Figure 31The structure of the rotating shaft device 22d in the fifth embodiment of this application is similar to that of the rotating shaft device 22 in the first embodiment described above. The difference is that the second rotating member 255 and the side support member 233 of the rotating shaft device 22d are connected by a second limiting groove and a second limiting part. The second limiting groove is provided in one of the second rotating member 255 and the side support member 233, and the second limiting part is provided in the other of the second rotating member 255 and the side support member 233. In this embodiment, a limiting block 2337 protrudes from the back surface 2332 of the side support member 233 corresponding to the second rotating member 255. The limiting block 2337 has an arc-shaped second limiting groove 2339. The second limiting groove 2339 penetrates the two opposite sides of the limiting block 2337 and bends and extends towards the side closer to the positioning seat 251. The second rotating member 255 has a second limiting part 2550 on its surface facing the limiting block 2337. The second limiting part 2550 is slidably and rotatably inserted into the second limiting groove 2339. During the folding or flattening process, the second limiting part 2550 slides and rotates along the second limiting groove 2339 of the rotating shaft device 22d.

[0112] Preferably, the second limiting groove 2339 is an arc-shaped groove, comprising a first limiting segment 2339a and a second limiting segment 2339b located at opposite ends. The first limiting segment 2339a is closer to the positioning seat 251 than the second limiting segment 2339b. The second limiting part 2550 is a second limiting shaft passing through the second limiting groove 2339. The second limiting shaft is located at the end of the second rotating member 255 away from the positioning seat 251, and the axis of the second limiting shaft is parallel to the axis of the second rotation C2. When the two side supports 233 are in a flattened state, the second limiting shaft is positioned at the second limiting segment 2339b to prevent the side supports 233 from folding back and damaging the flexible screen 30. When the two side supports 233 are in a fully folded state, the second limiting shaft is positioned at the first limiting segment 2339a to prevent the side supports 233 from folding further and damaging the flexible screen 30. During the bending process of the rotating shaft device 22d, the second limiting part 2550 on the second rotating member 255 slides and rotates in the second limiting groove 2339, and the second limiting part 2550 moves from the second limiting section 2339b to the first limiting section 2339a; during the flattening process of the rotating shaft device 22b, the second limiting part 2550 on the second rotating member 255 slides and rotates in the second limiting groove 2339, and the second limiting part 2550 moves from the first limiting section 2339a to the second limiting section 2339b.

[0113] In some embodiments, the second limiting portion 2550 on the second rotating member 255 and the second limiting groove 2339 on the side support member 233 can be interchanged. Specifically, the second limiting groove is provided on the side of the second rotating member 255 facing the limiting block 2337, and the second limiting shaft is provided on the limiting block 2337 of the side support member 233, which can be movably inserted into the second limiting groove.
