Description

Technical Field

[0001] This invention relates to the field of flexible component support, and more particularly to a pivot device for supporting a flexible component, a foldable housing provided with the pivot device, and an electronic device provided with the foldable housing. Background Technology

[0002] With the development of display equipment, flexible displays have emerged, and foldable phones equipped with these displays are becoming increasingly popular due to their unique shapes and diverse functions. Currently, flexible displays employ both inward and outward folding mechanisms. Foldable phones in related technologies generally use hinge mechanisms for support; however, most current hinge structures are complex, wide, and space-consuming, hindering the miniaturization of foldable phones. 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 rotating assembly, and a driven assembly. The support mechanism includes two side support members. The rotating assembly includes a positioning seat and two rotating mechanisms disposed on opposite sides of the positioning seat. Each rotating mechanism includes a first rotating member, a second rotating member, and a connecting member. The opposite ends of the first rotating member are rotatably connected to the positioning seat and the connecting member, respectively. The opposite ends of the second rotating member are also rotatably connected to the positioning seat and the connecting member, respectively. 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 two driven members corresponding to the two rotating mechanisms, respectively. The driven members are connected to the positioning seat and the connecting member. The side support and the connector on the same side of the seat are slidably and rotatably connected; wherein, the side support and the connector are rotatably connected, and when the two connectors approach each other, the first rotating member and the second rotating member rotate relative to the positioning seat and the connector and approach each other, and the driven member rotates relative to the positioning seat and slides and rotates relative to the connector and approaches each other, so that the two side support members fold towards each other; when the two connectors move away from each other, the first rotating member and the second rotating member rotate relative to the positioning seat and the connector and move away from each other, and the driven member rotates relative to the positioning seat and slides and rotates relative to the connector and moves away from each other, so that the two side support members unfold towards each other.

[0005] This application also provides a folding housing, which includes a pivot device and two frames. The pivot device is located between the two frames, and the two frames are respectively connected to the connecting parts of the two rotating mechanisms of the pivot device.

[0006] This application also provides an electronic device, which includes a flexible component and a folding housing, wherein the flexible component is disposed on the folding housing.

[0007] In this invention, the first rotation axis between the first rotating member and the connecting member of the rotating shaft device is parallel to the second rotation axis between the second rotating member and the connecting member. The first rotating member is slidably and rotatably connected to the side support member, and the driven member is slidably and rotatably connected to the side support member and the connecting member on the same side as the positioning seat. This makes the rotating shaft device compact in structure and smaller in overall width, thereby reducing the internal space occupied by the rotating shaft device in the folding shell. This is not only beneficial for the layout of other components such as the motherboard or battery inside the shell, but also beneficial for miniaturization. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0012] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installed," "connected," "linked," and "set on" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0013] Please refer to the following: Figures 1 to 7 The electronic device 100 in the first embodiment of the present invention includes a folding housing 20 and a flexible component 30 disposed on the folding housing 20. The flexible component 30 can be a flexible display screen, a flexible touch screen, or a flexible touch display screen, 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 component 30 bends or flattens with the folding housing 20. The folding housing 20 includes two frames 21 and a pivot device 22 connecting the two frames 21. The two frames 21 can be folded or flattened with the pivot device 22. The flexible component 30 includes a bendable region 31 corresponding to the pivot device 22, and two non-bendable regions 33 connected to opposite sides of the bendable region 31. The two non-bendable regions 33 of the flexible component 30 can be fixed to the front of the two frames 21 respectively, and the bendable region 31 is attached to the front of the pivot device 22. The bendable region 31 of the flexible component 30 can be bent or flattened with the pivot device 22.

[0014] The rotating shaft device 22 includes a support mechanism 23, a rotating assembly 25, and a driven assembly 26, with the driven assembly 26 connected to the rotating assembly 25. The support mechanism 23 includes two side support members 233 located on opposite sides of the front of the rotating assembly 25, which can be bent or flattened. The 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, facilitating the flexible member 30 to conform to 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. The two opposite ends of the first rotating member 254 are rotatably connected to the positioning seat 251 and the corresponding connecting member 256, respectively. The two opposite ends of the second rotating member 255 are also rotatably connected to the positioning seat 251 and the corresponding connecting member 256, respectively. 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 assembly 26 includes two driven members 264 corresponding to the two rotating mechanisms 253, respectively. Each driven member 264 is slidably and rotatably connected to the side support member 233 and the connecting member 256 on the same side of the positioning seat 251. Specifically, each follower 264 is slidably and rotatably connected to the side support 233, and each follower 264 is slidably and rotatably connected to the connector 256. In this embodiment, the follower assembly 26 also includes two rotating shafts 260 respectively disposed on the two followers 264. One end of the follower 264 can rotate around the corresponding rotating shaft 260, and the end of each follower 264 away from the rotating shaft 260 is slidably and rotatably connected to the corresponding side support 233 and connector 256 respectively. The side support member 233 is rotatably connected to the corresponding connector 256. When the two connectors 256 approach each other, the first rotating member 254 and the second rotating member 255 rotate relative to the positioning seat 251 and the connector 256 and approach each other. The follower 264 rotates relative to the positioning seat 251 and slides and rotates relative to the connector 256 and approaches each other, so that the two side support members 233 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 and move away from each other. The follower 264 rotates relative to the positioning seat 251 and slides and rotates relative to the connector 256 and moves away from each other, so that the two side support members 233 unfold together.

[0015] 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 bendable area 31 of the flexible member 30 is attached to 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 and the central support member form a space with a teardrop or U-shaped cross-section. 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 264 to rotate relative to the positioning seat 251 through the connectors 256, so that the two side support members 233 can be bent or unfolded with the rotating mechanism 253 and the driven member 264. The flexible member 30 bends or flattens with the support mechanism 23. The bendable area 31 can be bent into a U-shape, a teardrop shape or other shapes. In this embodiment, the bendable area 31 can be bent into a teardrop shape.

[0016] In this embodiment, the front side refers to the side facing the same direction as the light-emitting surface of the flexible component 30, and the back side refers to the side facing away from the light-emitting surface of the flexible component 30. The electronic device 100 is, for example, but not limited to, mobile phones, tablets, displays, 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 integrally formed and connected, while a non-integrated connection means that A and B are not integrally formed and connected.

[0017] The rotating shaft device 22 of the electronic device 100 of the present invention includes a support mechanism 23, a rotating assembly 25 and a driven assembly 26. One end of the first rotating member 254 of the 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 of the rotating assembly 25 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 264 away from the rotating shaft 260 is slidably and rotatably connected to the side support member 233 and the connecting member 256. As the two frames 21 move closer or further apart, 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 causes the two side support members 233 to fold or unfold relative to each other, thereby realizing the folding or flattening of the flexible member 30. First, since 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 parallel and misaligned, and the auxiliary member 264 is slidably and rotatably connected to the connecting member 256 and the side support member 233, and the connecting member 256 is rotatably connected to the side support member 233, 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 flexible parts 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.

[0018] The rotating shaft device 22 in this embodiment includes a rotating component 25 and a driven component 26; the rotating component 25 and the driven component 26 constitute an integral structure, which is disposed on the back of the support mechanism 23.

[0019] In some embodiments, the rotating shaft device 22 may also include two rotating components 25 and two driven components 26, the two rotating components 25 and the two driven components 26 respectively forming 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.

[0020] In some embodiments, the rotating shaft device 22 may also include only three or more rotating components 25 and three or more driven components 26. Each rotating component 25 and one of the driven components 26 form an integral structure, that is, three or more rotating components 25 and three or more driven components 26 form three or more integral structures. The three or more integral structures are respectively disposed on the back of the support mechanism 23 and are spaced apart along the length direction of the support mechanism 23.

[0021] 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; the second rotation axis C2 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. The rotation axis between the first rotating member 254 and the positioning seat 251 is parallel or collinear with the rotation axis between the second rotating member 255 and the positioning seat 251.

[0022] 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, the first direction is parallel to the width direction of the rotating device 22, and the second direction is parallel to the thickness direction of the rotating device 22.

[0023] like Figures 1 to 4As 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 264 to rotate relative to the positioning seat 251. The rotation of the rotating mechanism 253 and the driven part 264 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 bent into a teardrop shape or unfolded into a horizontal shape. The bendable area 31 of the flexible part 30 is folded into a teardrop shape or unfolded into a horizontal shape along with the bendable area 31.

[0024] 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 bendable area 31 of the flexible member 30 is attached to the front face of the pivot device 22, and the non-bending area 33 of the flexible member 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) for mounting electronic components such as circuit boards and batteries.

[0025] Please refer to the following: Figures 7-9The 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 plate 2330 includes a front side 2331 and a back side 2332 facing away from the front side 2331. 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 connector 256 is provided with a first arc rail 2562 that can be slidably inserted into the first arc groove 2334. The connector 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. 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] The driven member 264 and the side support member 233 are connected by a first limiting groove and a first limiting part. The first limiting groove is an arc-shaped groove and is provided on one of the driven member 264 and the side support member 233, while the first limiting part is provided on the other. In this embodiment, the side support member 233 is provided with a first limiting groove 2336, and the driven member 264 is provided with a first limiting part 2640. The first limiting part 2640 is slidably and rotatably accommodated in the first limiting groove 2336. Specifically, a first limiting block 2335 protrudes from the back surface 2332 of the side support member 233. The first limiting block 2335 has an arc-shaped first limiting groove 2336 that penetrates the two opposite sides of the first limiting block 2335. The first limiting groove 2336 bends and extends toward the back side 2332 away from the side support member 233. That is, the first end of the first limiting groove 2336 is close to the positioning seat 251, and the opposite second end of the first limiting groove 2336 is away from the positioning seat 251. The first limiting groove 2336 is formed by bending and extending from the first end to the second end, and the middle part of the first limiting groove 2336 is away from the back side 2332.

[0031] Preferably, the first limiting groove 2336 includes a first limiting segment 2336a and a second limiting segment 2336b located at opposite ends thereto, and a connecting segment 2336c connecting the first limiting segment 2336a and the second limiting segment 2336b. The first limiting segment 2336a is further away from the positioning seat 251 than the second limiting segment 2336b, and the connecting segment 2336c is bent toward the side away from the back surface 2332. The first limiting part 2640 includes a first limiting shaft passing through the first limiting groove 2336. During the folding or flattening process, the first limiting shaft can be displaced from the first limiting segment 2336a to the second limiting segment 2336b via the connecting segment 2336c, or the first limiting shaft can be displaced from the second limiting segment 2336b to the first limiting segment 2336a via the connecting segment 2336c. When the two side supports 233 are in a flattened state, the first limiting shaft is positioned at the first limiting segment 2336a (e.g., Figure 15 (as shown), to prevent the side support 233 from folding back and damaging the flexible component 30; when both side support 233 are in a fully folded state, the first limiting shaft is positioned at the second limiting segment 2336b (as shown). Figure 23 (as shown), to prevent the side support 233 from further folding and damaging the flexible part 30.

[0049] 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.

[0050] Please refer to the following: Figures 5-17When 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 connecting 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 tracks 2541 of the two first rotating members 254 are respectively housed in the two second arc grooves 2511 of the first base 2510, and the third arc tracks 2552 of the two second rotating members 255 are respectively housed in the two third arc grooves 2512 of the first base 2510. Then, the second base 2516 is placed over the first base 2510, such that the two first arc convex surfaces 2517 of the second base 2516 are respectively attached to the front surfaces of the two second arc tracks 2541, and the two second arc convex surfaces 2518 are respectively attached to the front surfaces of the two third arc tracks 2552, so that the first rotating members 254 and the second rotating members 255 are rotatably connected to the positioning base 251. At this time, the rotation axis C3 between the first rotating member 254 and the positioning base 251 is parallel and spaced apart from the rotation axis C4 between the second rotating member 255 and the positioning base 251.

[0051] Insert the two rotating shafts 260 into the two through holes 2624 of the fixing member 262 until the two positioning caps 2602 abut against the supporting member 273. Insert the ends of the two rotating shafts 260 away from the positioning caps 2602 into the two shaft holes 2646 of the two driven members 264 until the two driven members 264 approach the fixing member 262. The ends of the two rotating shafts 260 away from the positioning caps 2602 are also equipped with a limiting mechanism (not shown in the figure), which is positioned in the slot at the end of the rotating shaft 260. The driven component 26 and the limiting mechanism, which are assembled as a single unit, are placed at one end of the rotating component 25. The positioning caps 2602 of the two rotating shafts 260 are respectively accommodated in the two connecting holes 2515 of the positioning seat 251. The two driven members 264 are respectively accommodated in the clearance grooves 2568 of the two connecting members 256. The first connecting hole 2647 of the driven member 264 faces the second limiting groove 2567 of the connecting member 256, that is, the second connecting hole 2649 of the driven member 264 faces away from the second limiting groove 2567 of the connecting member 256. The two second limiting parts 2648 are respectively inserted into the two second limiting grooves 2567 and the two first connecting holes 2647, so that each second limiting part 2648 can slide and rotate in the corresponding second limiting groove 2567. The two side supports 233 are placed on opposite sides of the front of the rotating assembly 25, so that the second connecting holes 2649 of the two driven members 264 are respectively aligned with the first limiting grooves 2336 of the two side supports 233. The two first limiting parts 2640 are respectively inserted into the first limiting grooves 2336 and the second connecting holes 2649 of the side supports 233, so that each first limiting part 2640 can slide and rotate in the corresponding first limiting groove 2336.

[0052] The 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 track 2562 is rotatably accommodated in the corresponding first arc groove 2334. The first limiting part 2640 is positioned in the first limiting segment 2336a of the first limiting groove 2336, and the second limiting part 2648 is positioned in the first limiting segment 2567a of the second limiting groove 2567. When the two side supports 233 are bent, 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 track 2562 is rotatably accommodated in the corresponding first arc groove 2334. The first limiting part 2640 is positioned in the second limiting section 2336b of the first limiting groove 2336, and the second limiting part 2648 is positioned in the second limiting section 2567b of the second limiting groove 2567.

[0053] like Figure 7 and Figure 17As 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 member 254 and the positioning seat 251 is the axis of the virtual axis, and the rotation axis C4 between the second rotating member 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 member 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 member than the second rotation axis C2.

[0054] 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.

[0055] When the connecting member 256 drives the first rotating member 254, the second rotating member 255, and the driven member 264 to rotate relative to the positioning seat 251, the rotation of the rotating mechanism 253 and the driven member 264 causes the side support member 233 to rotate and slide relative to the positioning seat 251, so that the two side support members 233 bend 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; the second rotating member 255 rotates relative to the positioning seat 251 via the third arc track 2552 and the third arc groove 2512; the driven member 264 rotates with the rotating mechanism 253 along the corresponding rotating shaft 260, the first limiting part 2640 slides and rotates in the first limiting groove 2336, and the second limiting part 2648 slides in the second limiting groove 2567. 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 respectively 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 respectively rotatably connected to the connector 256, so as to realize the mutual bending or mutual unfolding of the two side support members 233.

[0056] like Figures 18-24 When the rotating shaft device 22 is bent from its flattened state, one of the connecting members 256 bends relative to the positioning seat 251 toward the other connecting member 256. This 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, 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, and drives the driven member 264 relative to the other connecting member 256. The positioning seat 251 rotates, causing the first limiting part 2640 on the driven member 264 to slide and rotate in the first limiting groove 2336, and the first limiting part 2640 moves from the first limiting segment 2336a to the second limiting segment 2336b; the second limiting part 2648 on the driven member 264 rotates and slides in the corresponding second limiting groove 2567, and the second limiting part 2648 moves from the first limiting segment 2567a to the second limiting segment 2567b. At the same time, the connecting member 256 drives the first arc track 2562 to rotate and connect to the corresponding first arc groove 2334, causing the driven members 264 on opposite sides to rotate relative to the positioning seat 251 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.

[0057] like Figures 19 to 25As shown, during the bending process of the side support member 233 relative to the positioning seat 251, the first limiting part 2640 moves from the first limiting segment 2336a of the first limiting groove 2336 to the second limiting segment 2336b, and the second limiting part 2648 moves from the first limiting segment 2567a of the second limiting groove 2567 to the second limiting segment 2567b. At the same time, the first rotating member 254 and the second rotating member 255 on both sides of the positioning seat 251 move closer to each other, so that the first rotation axis C1 on both sides of the positioning seat 251 moves closer to each other, and the second rotation axis C2 on both sides of the positioning seat 251 moves closer to each other, until the front of the two side support members 233 and the front of the positioning seat 251 form a space with a teardrop-shaped cross-section.

[0058] In other usage scenarios, the two connecting members 256 can rotate together in opposite directions, each first rotating member 254 can rotate relative to the corresponding second arc groove 2511 via the second arc rail 2541, each second rotating member 255 can rotate relative to the corresponding third arc groove 2512 via the third arc rail 2552, and each driven member 264 can rotate along the corresponding rotation axis 260. Simultaneously, the two connecting pieces 256 synchronously drive the two first arc rails 2562 to rotate in the first arc grooves 2334 of the two side support pieces 233. The first limiting part 2640 on the driven piece 264 slides and rotates in the first limiting groove 2336 of the corresponding side support piece 233, so that the first limiting part 2640 moves from the first limiting section 2336a to the second limiting section 2336b. The second limiting part 2648 on the driven piece 264 rotates and slides in the corresponding second limiting groove 2567, and the second limiting part 2648 moves from the first limiting section 2567a to the second limiting section 2567b. This causes the two side support pieces 233 to move closer to each other until the two side support pieces 233 and the positioning seat 251 form a teardrop shape in cross section.

[0059] When the rotating shaft device 22 is flattened from its bent state, one of the connecting members 256 unfolds relative to the positioning seat 251 away from the other connecting member 256. This 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, 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, and drives the driven member 264 to rotate relative to the positioning seat 251. This causes the first limiting part 2640 on the driven member 264 to slide and rotate in the first limiting groove 2336, and the first limiting part 2640 moves from the second limiting segment 2336b to the first limiting segment 2336a. The second limiting part 2648 on the driven member 264 rotates and slides in the corresponding second limiting groove 2567, and the second limiting part 2648 moves from the second limiting segment 2567b to the first limiting segment 2567a. 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 264 on both sides rotate relative to the positioning seat 251 and unfold to each other, so as to drive the two side support members 233 to unfold to each other until the two side support members 233 and the positioning seat 251 are flattened.

[0060] During the flattening process of the side support member 233 relative to the positioning seat 251, the first limiting part 2640 moves from the second limiting segment 2336b of the first limiting groove 2336 to the first limiting segment 2336a, and the second limiting part 2648 moves from the second limiting segment 2567b of the second limiting groove 2567 to the first limiting segment 2567a. At the same time, the first rotating member 254 and the second rotating member 255 on opposite sides of the positioning seat 251 move away from each other, so that the first rotation axis C1 on opposite sides of the positioning seat 251 moves away from each other, and the second rotation axis C2 on opposite sides of the positioning seat 251 moves away from each other, until the two side support members 233 are successfully flattened, so that the front of the two side support members 233 is coplanar with the front of the positioning seat 251.

[0061] In other usage scenarios, the two connecting members 256 can rotate together in directions away from each other, each first rotating member 254 can rotate relative to the corresponding second arc groove 2511 via the second arc rail 2541, each second rotating member 255 can rotate relative to the corresponding third arc groove 2512 via the third arc rail 2552, and each driven member 264 can rotate along the corresponding rotation axis 260. Simultaneously, the two connecting pieces 256 synchronously drive the two first arc rails 2562 to rotate in the first arc grooves 2334 of the two side supports 233. The first limiting part 2640 on the driven member 264 slides and rotates in the first limiting groove 2336 of the corresponding side support 233, so that the first limiting part 2640 moves from the second limiting section 2336b to the first limiting section 2336a. The second limiting part 2648 on the driven member 264 rotates and slides in the corresponding second limiting groove 2567, and the second limiting part 2648 moves from the second limiting section 2567b to the first limiting section 2567a. This causes the two side supports 233 to move away from each other until the front of the two side supports 233 is flush with the front of the positioning seat 251.

[0062] In some embodiments, the first limiting portion 2640 on the driven member 264 and the first limiting groove 2336 on the side support member 233 can be interchanged. That is, the first limiting groove 2336 can be provided on the driven member 264, the first limiting portion 2640 can be fixed to the side support member 233, and the first limiting portion 2640 is slidably and rotatably inserted into the first limiting groove 2336. Specifically, a limiting groove can be provided on the side of the driven member 264 facing the first limiting block 2335, and a limiting shaft that can be movably inserted into the limiting groove is provided on the first limiting block 2335 of the side support member 233. During the bending or unfolding process of the rotating shaft device 22, the limiting shaft slides and rotates in the limiting groove.

[0063] In some embodiments, the second limiting portion 2648 on the follower 264 and the second limiting groove 2567 on the connector 256 are interchangeable. That is, the second limiting groove 2567 can be provided on the follower 264, the second limiting portion 2648 can be fixed to the connector 256, and the second limiting portion 2648 is slidably and rotatably inserted into the second limiting groove 2567. Specifically, the second limiting groove 2567 can be provided on the surface of the support plate 2566 facing the connector 256 on the follower 264, and the second limiting portion 2648 is provided on the support plate 2566 of the connector 256 and can be movably inserted into the second limiting groove 2567. During the bending or unfolding process of the rotating shaft device 20, the second limiting portion 2648 slides and rotates in the second limiting groove 2567.

[0064] Please refer to the following: Figures 1-6The installed pivot 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 member 30 is connected to the front faces 211 of the two frames 21 and the front face of the pivot device 22. Specifically, the bendable area 31 is attached to the front face of the pivot device 22, and the two non-bendable areas 33 are respectively attached to the front faces of the two frames 21. When the flexible component 30 is in a flattened state, the front of the positioning seat 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 seat 251, the flexible component 30 is not subjected to impacts at the step difference when flattened, and thus avoids defects such as colored spots or bright spots, ensuring the reliability of the flexible component 30. This also improves the tactile feel of the flexible component 30 and enhances the user experience. Furthermore, the driven component 264 and the side supports 256 are connected by the first limiting groove 2336. The first limiting part 2640 is connected, and the driven member 264 and the connecting member 256 are connected through the second limiting part 2648 and the second limiting groove 2567. 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 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.

[0065] Please refer to the following: Figures 12-25When bending the electronic device 100, a bending 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 of mutual proximity. The bending of the shaft device 22 is achieved through the rotating assembly 25 and the driven member 26, and the bendable area 31 of the flexible member 30 bends with the shaft device 22. Specifically, if a bending force is applied to one of the frames 21, the frame 21 drives the corresponding first rotating member 254, second rotating member 255 and driven member 264 to rotate relative to the positioning seat 251 towards the side closer to the flexible member 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, and the third arc track 2552 of the second rotating member 255 rotates relative to the third arc groove 2511 of the positioning seat 251. The groove 2512 rotates relative to the first limiting part 2640 on the follower 264, which slides and rotates in the first limiting groove 2336. The first limiting part 2640 moves from the first limiting segment 2336a to the second limiting segment 2336b, and the second limiting part 2648 on the follower 264 rotates and slides in the corresponding second limiting groove 2567, and the second limiting part 2648 moves from the first limiting segment 2567a to the second limiting segment 2567b. Simultaneously, the connector 256 drives the first arc track 2562 to rotate and connect to the corresponding first arc groove 2334, causing the driven members 264 on both sides to rotate relative to the positioning seat 251 and move closer to each other, thereby driving 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; the bendable area 31 of the flexible member 30 bends with the rotating shaft device 22 until the front sides of the two non-bendable areas 33 of the flexible member 30 are in contact with each other, and the bendable area 31 is bent into a teardrop shape, thereby achieving seamless folding of the electronic device 100.

[0066] During the bending process of the electronic device 100, the bendable area 31 of the flexible component 30 is bent into a teardrop shape, reducing the duty cycle of the bendable area 31 after bending, thereby reducing the overall thickness of the electronic device 100.

[0067] In other bending methods of the electronic device 100, bending forces can be applied to both frames 21 at the same time. The two frames 21 drive the two rotating mechanisms 253 to rotate towards the side closer to the flexible member 30, and the bending of the electronic device 100 is achieved through the rotating shaft device 22.

[0068] When it is necessary to flatten the electronic device 100, 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. The frame 21 causes the corresponding first rotating member 254 to rotate relative to the positioning seat 251 away from the flexible member 30, and causes the corresponding second rotating member 255 to rotate relative to the positioning seat 251 away from the flexible member 30. A connecting member 256 causes the driven member 264 to rotate relative to the positioning seat 251, so that the first limiting part 2640 on the driven member 264 slides and rotates in the first limiting groove 2336, and the first limiting part 2640 moves from the second limiting segment 2336b to the first limiting segment 2336a. The second limiting part 2648 on the driven member 264 rotates and slides in the corresponding second limiting groove 2567, and the second limiting part 2648 moves from the second limiting segment 2567b to the first limiting segment 2567a. Simultaneously, 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 264 on both sides rotate relative to the positioning seat 251 and unfold to each other, so as to drive the two side support members 233 to unfold to each other until the two side support members 233 and the positioning seat 251 are flattened, and the bendable area 31 of the flexible member 30 unfolds with the rotating shaft device 22 until the flexible member 30 is flattened.

[0069] In other bending 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 to rotate relative to the side away from the flexible member 30, and the electronic device 100 is unfolded through the rotating shaft device 22.

[0070] The rotating shaft device 22 of the electronic device 100 of the present invention achieves bending or unfolding through the rotating assembly 25 and the driven assembly 26. Since the first rotation axis C1 between the first rotating member 254 and the connecting member 256 is parallel and misaligned with the second rotation axis C2 between the second rotating member 255 and the connecting member 256, the driven member 264 and the side support member 233 are connected by an arc-shaped first limiting groove 2336 and a first limiting part 2640, and the driven member 264 and the connecting member 256 are connected by an arc-shaped second limiting groove 2567 and a second limiting part 2648. 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 housing 20, and facilitating the layout of other components such as the motherboard or battery. Secondly, the rotating shaft device 22 has a robust structure, which improves the overall strength of the electronic device 100.

[0071] Please see Figure 26 and Figure 27The 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 described above. The difference is that the first rotating member 254 and the side support member 233 of the rotating shaft device 22a are connected by a third limiting groove and a third limiting part. The third limiting groove is provided on one of the first rotating member 254 and the side support member 233, and the third limiting part is provided on the other of the first rotating member 254 and the side support member 233. In this embodiment, a first limiting block 2337 protrudes from the back surface 2332 of the side support member 233 corresponding to the first rotating member 254. The first limiting block 2337 has an arc-shaped third limiting groove 2338 that penetrates the two opposite sides of the first 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 first limiting block 2337 is provided with a third limiting part 2540, which is slidably and rotatably inserted into the third limiting groove 2338. Specifically, a connecting hole is provided on one side of the connecting part 2542 near the shaft hole 2544, and the third limiting part 2540 is connected to the connecting hole. In this embodiment, a connecting cylinder protrudes from one side of the connecting part 2542 near the shaft hole 2544, and the third limiting part 2540 is connected to the inner cavity of the connecting cylinder; further, the third limiting part 2540 is a third limiting shaft inserted and fixed in the inner cavity of the connecting cylinder, and the axis of the third limiting shaft is parallel to the axis of the second arc track 2541. One end of the third limiting part 2540 is fixedly connected to the connecting part 2542, and the other end of the third limiting part 2540 is used to slide and rotatably pass through the third limiting groove 2338 of the side support member 233. In some embodiments, the third limiting portion 2540 may also be integrally formed with the first rotating member 254. During the folding or flattening process, the third limiting portion 2540 slides and rotates along the third limiting groove 2338 of the rotating shaft device 22a.

[0072] Preferably, the third 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 third limiting shaft is located at the end of the first rotating member 254 away from the positioning seat 251, and the axis of the third limiting shaft is parallel to the axis of the first rotating member C1. When the two side supports 233 are in a flattened state, the third limiting shaft is positioned at the second limiting segment 2338b to prevent the side supports 233 from folding back and damaging the flexible member 30. When the two side supports 233 are in a fully folded state, the third limiting shaft is positioned at the first limiting segment 2338a to prevent the side supports 233 from folding further and damaging the flexible member 30. During the bending process of the rotating shaft device 22a, the third limiting part 2540 on the first rotating member 254 slides and rotates in the third limiting groove 2338, and the third limiting part 2540 moves from the second limiting section 2338b to the first limiting section 2338a; during the flattening process of the rotating device 22a, the third limiting part 2540 on the first rotating member 254 slides and rotates in the third limiting groove 2338, and the third limiting part 2540 moves from the first limiting section 2338a to the second limiting section 2338b.

[0073] In some embodiments, the third limiting portion 2540 on the first rotating member 254 and the third limiting groove 2338 on the side support member 233 can be interchanged. Specifically, the first rotating member 254 has a third limiting groove on the side facing the first limiting block 2337, and the first limiting block 2335 of the side support member 233 has a third limiting shaft that can be movably inserted into the third limiting groove. During the bending or unfolding process of the rotating shaft device 22a, the third limiting shaft slides and rotates in the third limiting groove.

[0074] This application also provides an electronic device equipped with a pivot device 22a, the electronic device including two frames connected to connectors 256 on opposite sides of the pivot device 22a and a flexible member 30 covering the frames and the pivot device 22a.

[0075] Please see Figure 28 and Figure 29The 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 second rotating member 255 and the side support member 233 of the rotating shaft device 22b are connected by a fourth limiting groove and a fourth limiting part. The fourth limiting groove is provided on one of the second rotating member 255 and the side support member 233, and the fourth limiting part is provided on the other of the second rotating member 255 and the side support member 233. In this embodiment, a first limiting block 2337 protrudes from the back surface 2332 of the side support member 233 corresponding to the second rotating member 255. The first limiting block 2337 has an arc-shaped fourth limiting groove 2339, which penetrates the two opposite sides of the first limiting block 2337 and bends and extends towards the side closer to the positioning seat 251. The second rotating member 255 has a fourth limiting part 2550 on its surface facing the first limiting block 2337. The fourth limiting part 2550 is slidably and rotatably inserted into the fourth limiting groove 2339. During the folding or flattening process, the fourth limiting part 2550 slides and rotates along the fourth limiting groove 2339 of the rotating shaft device 22b.

[0076] Preferably, the fourth 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 fourth limiting part 2550 is a fourth limiting shaft passing through the fourth limiting groove 2339. The fourth limiting shaft is located at the end of the second rotating member 255 away from the positioning seat 251, and the axis of the fourth limiting shaft is parallel to the axis of the second rotating member C2. When the two side supports 233 are in a flattened state, the fourth limiting shaft is positioned at the second limiting segment 2339b to prevent the side supports 233 from folding back and damaging the flexible member 30. When the two side supports 233 are in a fully folded state, the fourth limiting shaft is positioned at the first limiting segment 2339a to prevent the side supports 233 from folding further and damaging the flexible member 30. During the bending process of the rotating shaft device 22b, the fourth limiting part 2550 on the second rotating member 255 slides and rotates in the fourth limiting groove 2339, and the fourth limiting part 2550 moves from the second limiting section 2339b to the first limiting section 2339a; during the flattening process of the rotating device 22b, the fourth limiting part 2550 on the second rotating member 255 slides and rotates in the fourth limiting groove 2339, and the fourth limiting part 2550 moves from the first limiting section 2339a to the second limiting section 2339b.

[0077] In some embodiments, the fourth limiting portion 2550 on the second rotating member 255 and the fourth limiting groove 2339 on the side support member 233 can be interchanged. Specifically, the second rotating member 255 is provided with a fourth limiting groove on the side facing the first limiting block 2337, and the first limiting block 2337 of the side support member 233 is provided with a fourth limiting shaft that can be movably inserted into the fourth limiting groove. During the bending or unfolding process of the rotating shaft device 22b, the fourth limiting shaft slides and rotates in the fourth limiting groove.

[0078] This application also provides an electronic device equipped with a pivot device 22b, the electronic device including two frames connected to connectors 256 on opposite sides of the pivot device 22b and a flexible member 30 covering the frames and the pivot device 22b.

[0079] Please refer to the following: Figure 30 and Figure 31The 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 are connected by a third limiting groove and a third limiting part. The third limiting groove is provided in one of the first rotating member 254 and the side support member 233, and the third limiting part is provided in the other of the first rotating member 254 and the side support member 233. Furthermore, the second rotating member 255 and the side support member 233 of the rotating shaft device 22c are connected by a fourth limiting groove and a fourth limiting part. The fourth limiting groove is provided in one of the second rotating member 255 and the side support member 233, and the fourth limiting part is provided in the other of the second rotating member 255 and the side support member 233. In this embodiment, the back surface 2332 of the side support member 233 is provided with a first limiting block 2337 corresponding to the first rotating member 254 and the second rotating member 255, respectively. An arc-shaped third limiting groove 2338 is formed on the first limiting block 2337 corresponding to the first rotating member 254. The third limiting groove 2338 penetrates the two opposite sides of the first limiting block 2337 and bends and extends towards the side closer to the positioning seat 251. An arc-shaped fourth limiting groove 2339 is formed on the first limiting block 2337 corresponding to the second rotating member 255. The fourth limiting groove 2339 penetrates the two opposite sides of the first limiting block 2337 and bends and extends towards the side closer to the positioning seat 251. The first rotating member 254 has a third limiting part 2540 on its surface facing the first limiting block 2337. The third limiting part 2540 is slidably and rotatably inserted into the third limiting groove 2338. The second rotating member 255 has a fourth limiting part 2550 on its surface facing the first limiting block 2337. The fourth limiting part 2550 is slidably and rotatably inserted into the fourth limiting groove 2339. During the folding or flattening process, the third limiting part 2540 slides and rotates along the third limiting groove 2338, while the fourth limiting part 2550 slides and rotates along the fourth limiting groove 2339.

[0080] Preferably, both the third limiting groove 2338 and the fourth limiting groove 2339 are arc-shaped grooves. The third limiting groove 2338 includes a first limiting segment 2338a and a second limiting segment 2338b located at opposite ends of the groove, with the first limiting segment 2338a being closer to the positioning seat 251 than the second limiting segment 2338b.
