[0068] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0069] These embodiments are provided to make the disclosure thorough and complete, and to fully express the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, material composition, numerical expressions, and values ​​set forth in these embodiments should be interpreted as exemplary only and not as limiting.

[0070] It should be noted that, in the description of this disclosure, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientation or positional relationship, are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0071] Furthermore, the terms "first," "second," and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. "Vertical" is not strictly vertical, but within the permissible margin of error. "Parallel" is not strictly parallel, but within the permissible margin of error. Terms such as "including" or "contains" mean that the element preceding the word encompasses the element listed after the word, and do not exclude the possibility of encompassing other elements as well.

[0072] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure depending on the specific circumstances. When a particular device is described as being located between a first device and a second device, an intermediary device may or may not be present between the particular device and the first or second device.

[0073] All terms used in this disclosure have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0074] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0075] The applicant's research revealed that the dimensional requirements of the pivot structure in the length direction (the extension direction of the base) are limited by the dimensions and layout of each component in that direction. To meet strength requirements, the dimensions of components in the length direction generally need to meet predetermined values ​​and cannot be reduced. In terms of layout, symmetrical (aligned) or partially symmetrical (aligned) structures of different components in the length direction can effectively shorten the length requirement. However, symmetrical arrangement in the length direction undoubtedly increases the dimensional requirements of the pivot structure in the width direction (perpendicular to the extension direction of the base). For example, if connectors are symmetrically arranged on both sides of the base, and these connectors are movably connected to the base via grooves or tracks (such as curved tracks), then the arrangement of grooves or tracks for the two connectors at the same position along the extension direction of the base is required, ensuring that the width of the pivot structure is not less than the dimensions of the two grooves or tracks, thus preventing further reduction in the width of the pivot structure.

[0076] Therefore, as Figures 1-12 As shown, this application embodiment provides a rotating shaft structure, which may include a base 300, a first support component 100, a second support component 200, and a movable connecting assembly 400.

[0077] The first support member 100 is movable relative to the base 300; and the second support member 200 is movable relative to the base 300. The first support member 100 and the second support member 200 can be arranged along a direction perpendicular to the extension of the base 300 and disposed on both sides of the base 300. That is, the first support member 100, the base 300, and the second support member 200 are arranged sequentially along a direction perpendicular to the extension of the base 300. The first support member 100 and the second support member 200 can also be symmetrically or asymmetrically arranged relative to the base 300. The structures of the first support member 100 and the second support member 200 can be symmetrical along a centerline oriented along the extension direction of the base 300, so that the base 300, the first support member 100, and the second support member 200 form a symmetrical combination structure symmetrical along the centerline of the base 300.

[0078] The movable connection assembly 400 may include a first mating member 410 connecting the base 300 and the first support member 100 and a second mating member 420 connecting the base 300 and the second support member 200. That is, the base 300 and the first support member 100 can move relative to each other through the connection of the first mating member 410, and the base 300 and the second support member 200 can move relative to each other through the connection of the second mating member 420.

[0079] The first mating member 410 is movable relative to the base 300 and the second mating member 420 is movable relative to the base 300, so that the first support member 100 and the second support member 200 can switch between a first relative position and a second relative position. It is understood that the position of the first support member 100 relative to the base 300 in the first relative position is different from the position of the first support member 100 relative to the base 300 in the second relative position, and the position of the second support member 200 relative to the base 300 in the first relative position is different from the position of the second support member 200 relative to the base 300 in the second relative position.

[0080] In the first relative position, the base 300, the first support member 100, and the second support member 200 can form a first support structure, which can support the components it supports (such as flexible screens, chain structures, or flexible plates). The supported components can form different structures depending on the support structure. The first mating member 410 can include a first portion 411, and the second mating member 420 can include a second portion 421. The first mating member 410 can have the first portion 411 on the side closer to the second mating member 420, and the second mating member 420 can have the second portion 421 on the side closer to the first mating member 410. In the first relative position, the first portion 411 and the second portion 421 are close to each other, and along the extending direction of the base 300, the projections of the first portion 411 and the second portion 421 at least partially overlap; that is, the projections of the close portions of the first mating member 410 and the second mating member 420 can at least partially overlap along the extending direction of the base 300. The projection of the overlapping portion can include the projection of the first portion 411 and the projection of the second portion 421, that is, the projections of the first portion 411 and the second portion 421 completely overlap. Alternatively, the projection of the overlapping portion can include a partial projection of the first portion 411 and a partial projection of the second portion 421, that is, a partial projection of the first portion 411 and a partial projection of the second portion 421 overlaps, while other projections do not overlap. Furthermore, the projection of the overlapping portion can include the entire projection of one of the first portion 411 and the second portion 421 and a partial projection of the other. For example, if the projection of the overlapping portion includes the entire projection of the first portion 411 and a partial projection of the second portion 421, then the entire projection of the first portion 411 and a partial projection of the second portion 421 overlap, while other projections do not overlap.

[0081] Other parts of the first mating member 410 and the second mating member 420 (such as mutually distant parts) may not overlap. However, in other possible cases, other parts of the first mating member 410 and the second mating member 420 (such as mutually distant parts) may overlap, so that the dimensions of the first mating member 410 and the second mating member 420 along the extension direction (length) of the base 300 can meet predetermined values, and the layout can partially intersect to reduce the dimensional restrictions perpendicular to the extension direction (width) of the base 300. The first part 411 and the second part 421 may correspond or not, and the first mating member 410 and the second mating member 420 may be located at the same or substantially the same position along the extension direction of the base 300, so that the first part 411 and the second part 421 can approach each other in the first relative position. Furthermore, since the projections of the first portion 411 and the second portion 421 along the extension direction of the base 300 at least partially overlap, it is only necessary to allow the first portion 411 and the second portion 421 to be arranged crosswise (staggered or offset) to reduce the restriction on the width of the base 300 (perpendicular to the extension direction of the base 300), so as to meet the needs of the first mating member 410 moving relative to the base 300 and the second mating member 420 moving relative to the base 300; and, other portions of the first mating member 410 and the second mating member 420 along the extension direction of the base 300 can correspond (such as aligned or partially aligned), thereby reducing the space occupied by the first mating member 410 and the second mating member 420 along the extension direction of the base 300.

[0082] The extension direction of the base 300 can be the axis of rotation of the first mating member 410 relative to the first support member 100. The extension direction of the base 300 can be perpendicular to the arrangement direction of the base 300 and the first support member 100.

[0083] The base 300 can serve as a reference point for the rotating shaft structure during structural deformation. That is, the first support member 100 and the second support member 200 can move relative to the base 300, allowing the first and second bodies connected by the rotating shaft structure to assume different postures. Specifically, as the electronic device using this rotating shaft structure changes posture, the positions of the first and second bodies connected to the rotating shaft structure relative to the base 300 change. The first support member 100 and the second support member 200 can be symmetrically arranged relative to the base 300.

[0084] The first support member 100 and the second support member 200 can provide support for components (such as flexible screens, flexible circuit boards, etc.) in electronic devices that require support. In embodiments where the component is a flexible screen, the first support member 100 and the second support member 200 are movable relative to the base 300, and the direction of the support force and the formed support structure can be adjusted to meet the support requirements of the flexible screen under different usage conditions.

[0085] The movable connection assembly 400 serves as an assembly for movably connecting the first support member 100 and the second support member 200 to the base 300, and includes a first mating member 410 and a second mating member 420. Taking the first mating member 410 as an example, the first mating member 410 movably connects the first support member 100 and the base 300, so that the first support member 100 will not separate from the base 300 during its movement relative to the base 300.

[0086] The first portion of the first mating member 410 and the second portion of the second mating member 420 can move closer and further apart during switching between different relative positions. If the first portion 411 of the first mating member 410 and the second portion 421 of the second mating member 420 are aligned or substantially aligned (at least partially aligned) along the extension direction perpendicular to the base 300, then at least during the switching from the second relative position to the first relative position, the first portion 411 of the first mating member 410 and the second portion 421 of the second mating member 420 will interfere (impact), preventing the first support member 100 and the second support member 200 from switching to the first relative position. Therefore, it is necessary to misalign (non-align) the first portion 411 of the first mating member 410 and the second portion 421 of the second mating member 420 along the extension direction perpendicular to the base 300. Since the projections of the first portion 411 and the second portion 421 along the extension direction of the base 300 at least partially overlap, the first support member 100 and the second support member 200 can switch to the first relative position.

[0087] In the second relative position, the base 300, the first support member 100 and the second support member 200 form a second support structure, and the first support structure and the second support structure may be different.

[0088] In the second relative position, the projections of the first part 411 and the second part 421 may not overlap along the extension direction of the base 300. That is, in the second relative position, the first part 411 and the second part 421 may be relatively independent in the extension direction of the base 300, so as to drive the first support member 100 and the second support member 200 to form different support structures relative to the base 300.

[0089] The first mating member 410 and the second mating member 420 can be symmetrically arranged along the extension direction perpendicular to the base 300, that is, the first mating member 410 and the second mating member 420 are located at the same position in the extension direction of the base 300. Alternatively, the first mating member 410 and the second mating member 420 can be partially aligned along the extension direction perpendicular to the base 300, that is, portions of the first mating member 410 and portions of the second mating member 420 are located at the same position in the extension direction of the base 300. With the above arrangement, the projections of the first mating member 410 and the second mating member 420 along the extension direction perpendicular to the base 300 at least partially overlap, so as to reduce the size requirements of the base 300 along its extension direction (length).

[0090] In some embodiments, the first mating member 410 and the second mating member 420 may be partially aligned along an extension direction perpendicular to the base 300. The base 300 has a first guide structure 301 and a second guide structure 302; along the extension direction of the base 300, the first guide structure 301 has a first guide region 3011 and a second guide region 3012, and the second guide structure 302 has a third guide region 3021 and a fourth guide region 3022. The second guide region 3012 and the third guide region 3021 are correspondingly arranged and have an intersecting region, and the first guide region 3011 and the fourth guide region 3022 are located on both sides of the intersecting region.

[0091] The first guide region 3011 can be located on one side of the intersecting region. Therefore, in the first relative position, the third part 413 can be guided to the first guide region 3011 so that the projection of the third part 413 along the extension direction of the base 300 can at least partially overlap with the projection of the first part 411. That is, since the first part 411 is located at the intersecting position, the first guide structure 301 cannot guide the first part 411. The third part 413 can guide the first mating member 410 by cooperating with the first guide region 3011. That is, in the first relative position, even if the first part 411 cannot slide with the first guide structure 301, the first mating member 410 can slide with the first guide structure 301 through the third part 413 so that the positions of the first part 411 and the third part 413 of the first mating member 410 can be guided and supported by the first guide structure 301.

[0092] Furthermore, the fourth guide region 3022 can be located on one side of the intersecting region. Therefore, in the first relative position, the fourth part 423 can be guided to the fourth guide region 3022 so that the fourth part 423 can at least partially overlap with the projection of the second part 421 along the extension direction of the base 300. That is, since the second part 421 is located at the intersecting position, the second guide structure 302 cannot guide the second part 421. The fourth part 423 can guide the second mating member 420 by cooperating with the fourth guide region 3022. That is, in the first relative position, even if the second part 421 cannot slide with the second guide structure 302, the second mating member 420 can slide with the second guide structure 302 through the fourth part 423 so that the positions of the second part 421 and the fourth part 423 of the second mating member 420 can be guided and supported by the second guide structure 302.

[0093] That is, the portion of the first mating member 410 slidably disposed in the second guide region 3012 (including the first portion 411) and the portion of the second mating member 420 slidably disposed in the third guide region 3021 (including the second portion 421) can satisfy the condition of being aligned along the extension direction perpendicular to the base 300. The portion of the first mating member 410 slidably disposed in the first guide region 3011 and the portion of the second mating member 420 slidably disposed in the fourth guide region 3022 can be located at different positions of the base 300 along its extension direction, and are staggered along the extension direction perpendicular to the base 300.

[0094] The first part 411 can be slidably set in the second guide area 3012, and the second part 421 can be slidably set in the third guide area 3021. Furthermore, the first mating member 410 may include a third portion 413 slidably disposed in the first guide region 3011, and the second mating member 420 may include a fourth portion 423 slidably disposed in the fourth guide region 3022; that is, the first portion 411 and the third portion 413 of the first guide region 3011 are arranged along the extension direction (length) of the base 300, the second portion 421 and the fourth portion 423 of the first guide region 3011 are arranged along the extension direction (length) of the base 300, and the size (length) of the first guide structure 301 and the second guide structure 302 arranged on the base 300 is the sum of the sizes of the first guide structure 301 and the second guide structure 302 along the extension direction (length) of the base 300 minus the size of the second guide region 3012 (or the third guide region 3021) along the extension direction (length) of the base 300, effectively reducing the size requirement of the base 300 for setting the first guide structure 301 and the second guide structure 302. Furthermore, in the first relative position, the first part 411 and the second part 421 are located in the intersecting region.

[0095] To facilitate the limiting operation, the third part 413 may have a first limiting part 414 that cooperates with the first guide region 3011. In the second relative position, the first mating member 410 and the first guide structure 301 are limited by the first limiting part 414. Since the first limiting part 414 is provided in the third part 413 and can cooperate with the first guide region 3011.

[0096] like Figure 6 As shown, in some embodiments, the first limiting part 414 may be located on the side of the third part 413 opposite to the first part 411. The first guide region 3011 has a protrusion with a limiting surface that engages with the first limiting part 414. In the second relative position, the first limiting part 414 contacts the limiting surface to achieve a limiting function. The first limiting part 414 is located away from both the second guide region 3012 and the first guide region 3011 to avoid interference between the first limiting part 414 and the second part 421 located in the intersecting region, and also to prevent the protrusion in the second guide region 3012 from hindering the movement of the first part 411.

[0097] Alternatively, the first limiting part 414 and the first guide area 3011 can form other limiting structures. For example, the third part 413 has a groove structure, and the first guide area 3011 has a protrusion structure embedded in the groove structure. During the switching between the first relative position and the second relative position, the protrusion structure slides along the groove structure, and the groove structure has a groove inner wall as a limit, so that the groove inner wall and the protrusion structure make limiting contact in the second relative position.

[0098] Alternatively, the fourth portion 423 can have a second limiting portion 424 that mates with the fourth guide region 3022. In the second relative position, the second mating member 420 and the second guide structure 302 are limited by the second limiting portion 424. Similarly, the second limiting portion 424 can be located on the side of the fourth portion 423 opposite to the second portion 421. The fourth guide region 3022 has a protrusion with a limiting surface that mates with the second limiting portion 424. In the second relative position, the second limiting portion 424 contacts the limiting surface to achieve the limiting function.

[0099] The first guide structure 301 and the second guide structure 302 can guide the movement of mating parts (such as the first mating part 410 and the second mating part 420) relative to the base 300. Taking the first guide structure 301 as an example, the first guide structure 301 can guide the movement of the first mating part 410 relative to the base 300, and the corresponding structure of the first guide structure 301 can correspond to the trajectory of the first mating part 410 relative to the base 300. The first guide structure 301 can be a groove, and the surface of the first mating part 410 can move in conjunction with the groove wall.

[0100] The first guide structure 301 has a first guide region 3011 and a second guide region 3012, and the second guide structure 302 has a third guide region 3021 and a fourth guide region 3022. Different guide regions of the same guide structure can mate with different parts of a mating component, and the different guide regions of the same guide structure guide the mating component in the same direction. Taking the first guide structure 301 as an example, the first guide region 3011 mates with the third part 413 of the first mating component 410, and the second guide region 3012 mates with the first part 411 of the first mating component 410. During the movement of the first mating component 410 relative to the first guide structure 301, different parts of the first mating component 410 (such as the first part 411 and the third part 413) and different guide regions of the first guide structure 301 (such as the second guide region 3012 and the first guide region 3011) move synchronously.

[0101] The intersecting region is the area where different guide structures overlap. Specifically, the intersecting region is the area where the second guide region 3012 and the third guide region 3021 overlap. That is, both the second guide region 3012 and the third guide region 3021 include the intersecting region, so that the first part 411 moving along the second guide region 3012 and the second part 421 moving along the third guide region 3021 can both move to the intersecting region.

[0102] In other embodiments, the pivot structure includes a limiting mechanism for limiting the first support member 100 and the second support member 200 in a first relative position and / or a second relative position. The limiting mechanism connects the base 300 to the end of the first support member 100 on the same side, and faces the support surface of the base 300. The projection area of ​​the limiting mechanism is at least partially located outside the projection area of ​​the base 300 and / or the first support member 100. The limiting mechanism can be connected from the end of the base 300 on the same side as the first support member 100, facilitating its installation.

[0103] The limiting mechanism may include at least two connecting components, with different connecting components connecting different support members and the base 300. The limiting mechanism may include a first connecting component and a second connecting component, wherein the first connecting component connects the ends of the first support member 100 and the base 300 on the same side, and the second connecting component connects the ends of the second support member 200 and the base 300 on the same side.

[0104] Taking the first connecting assembly as an example, the first connecting assembly may include a first base connecting rod and a first support connecting rod that are rotatably connected. The end of the first base connecting rod away from the first support connecting rod has a first connecting portion, and the end of the first support connecting rod away from the first base connecting rod has a second connecting portion. That is, the first connecting assembly can be a connecting rod group.

[0105] The end face of the base 300 has a target trajectory structure, which has a first end and a second end facing away from each other. The first connecting part slides and rotates along the target trajectory structure, and the second connecting part is rotatably connected to the first support member 100.

[0106] During the relative rotation of the first base connecting rod and the first support connecting rod, the distance between the first connecting part and the second connecting part changes.

[0107] During the switching between the first relative position and the second relative position, the first base link and the first support link can rotate relative to each other, causing the second connecting part to rotate relative to the first support component 100 and drive the first connecting part to move along the target trajectory structure.

[0108] Furthermore, in the first relative position, the first base connecting rod and the first support connecting rod form a first target angle, so that the first connecting part and the second connecting part have a first distance, and the first connecting part is confined to the first end; in the second relative position, the first base connecting rod and the first support connecting rod form a second target angle, so that the first connecting part and the second connecting part have a second distance, and the first connecting part is confined to the second end. By setting the first connecting assembly as a connecting rod structure, the limiting function is achieved, and the processing and installation of the first connecting assembly are further facilitated.

[0109] To avoid interference between the first part 411 and the second part 421 in the intersecting area, a first avoidance area 412 can be formed between the first part 411 and the third part 413; and a second avoidance area 422 can be formed between the second part 421 and the fourth part 423. The first avoidance area 412 can correspond to the second guide area 3012, and the second avoidance area 422 can correspond to the third guide area 3021.

[0110] The avoidance area is the area without a solid structure. Taking the first avoidance area 412 as an example, the first part 411 and the third part 413 are the solid parts of the first mating part 410. The first part 411 and the third part 413 are arranged along the extension direction of the base 300, and there is a gap between the first part 411 and the third part 413. The empty part formed by this gap is the first avoidance area 412.

[0111] like Figure 6 and Figure 12 As shown, in the first relative position, the first part 411 can be located in the second avoidance area 422, and the second part 421 can be located in the first avoidance area 412. That is, the first part 411 and the second avoidance area 422 are in concave-convex fit, and the second part 421 and the first avoidance area 412 are in concave-convex fit.

[0112] In some embodiments, the first portion 411 may have a first surface facing the second portion 421 and a second surface facing the fourth portion 423. In the first relative position, the first surface and the second portion 421 may be in a limiting fit along the extension direction of the base, and the second surface may also be in a limiting fit with the fourth portion 423. That is, in the first relative position, at least one of the first portion 411 of the first mating member 410 and the second portion 421 and the fourth portion 423 of the second mating member 420 are in limiting contact along the extension direction of the base to improve the structural stability in the first relative position. When subjected to external impact (such as falling or impact), the first mating member 410 and the second mating member 420 can be limited along the extension direction of the base, reducing the probability of displacement of the first mating member 410 and the second mating member 420, thereby effectively improving the impact resistance.

[0113] Alternatively, the second part 421 can have a third surface facing the first part 411 and a fourth surface facing the third part 413. In the first relative position, along the extension direction of the base, the third surface is in a limiting fit with the first part 411 and / or the fourth surface is in a limiting fit with the third part 413. Similarly, this can also improve the structural stability in the first relative position. When subjected to external impact (such as falling or impact), the first mating part 410 and the second mating part 420 can be limited along the extension direction of the base, reducing the probability of displacement of the first mating part 410 and the second mating part 420, thereby effectively improving the impact resistance.

[0114] In some implementations, such as Figure 4 , Figure 5 , Figure 10 and Figure 11 As shown, along the support surface of the base 300, the base 300 may have a detachable first base component 310 and a second base component 320; the first base component 310 may have a first guide portion and a second guide portion, and the second base component 320 may have a third guide portion and a fourth guide portion; when the first base component 310 and the second base component 320 are connected, the first guide portion and the third guide portion may form a first guide structure 301, or the second guide portion and the fourth guide portion may form a second guide structure 302. That is, the structure of a single component can be simplified to improve the yield rate. Furthermore, it is convenient to provide protrusions within the guide structure and to facilitate assembly with corresponding mating parts.

[0115] The aforementioned different guide parts can serve as components of the guide structure. Taking the first guide structure 301 as an example, the first guide part and the third guide part can be half-grooves, and the combination of the first guide part and the third guide part forms the groove that serves as the first guide structure 301.

[0116] The second base component 320 may have at least one of a first connecting region 303 and a second connecting region 304. The first connecting region 303 and the first guide region 3011 may be located on opposite sides of the centerline along the extension direction of the base 300 and are correspondingly arranged. The second connecting region 304 and the fourth guide region 3022 may be located on opposite sides of the centerline along the extension direction of the base 300 and are correspondingly arranged. The first base component 310 is connected to the second base component 320 through at least one of the first connecting region 303 and the second connecting region 304. This arrangement ensures that the connecting region is as close as possible to the guide region, thereby improving the structural stability of the guide regions (first guide structure 301 and second guide structure 302) when the first base component 310 and the second base component 320 are connected.

[0117] The connection areas (first connection area 303 and / or second connection area 304) may have bolt holes or snap-fit ​​structures to facilitate connection. The connection areas may be solid portions of the base 300, arranged adjacent to the groove serving as a guide structure.

[0118] In some embodiments, the first support member 100 and the second support member 200 are symmetrically arranged with respect to the base 300.

[0119] It can also make the first support member 100 and the second support member 200 move synchronously relative to the base 300. That is, the first support member 100 is subjected to an external force to move relative to the base 300, and the second support member 200 also moves with the base 300.

[0120] In some other embodiments, the first guide structure 301 and the second guide structure 302 may be arranged symmetrically, that is, the first guide structure 301 and the second guide structure 302 are aligned along the extension direction perpendicular to the base 300.

[0121] The first mating member 410 can also be detachably connected to the first support member 100; and / or, the second mating member 420 can be detachably connected to the second support member 200. The two can be connected by bolts or clips.

[0122] In some embodiments, the rotating shaft structure further includes a first connecting member 500 and a second connecting member 600. The first connecting member 500 is movably connected to the first supporting member 100 via a third trajectory structure 430, and the second connecting member 600 is movably connected to the second supporting member 200 via a fourth trajectory structure 440. That is, along the extension direction perpendicular to the base 300, the first connecting member 500, the first supporting member 100, the base 300, the second supporting member 200, and the second connecting member 600 are arranged sequentially to form a five-segment structure. In other embodiments, the first connecting member 500 and the second connecting member 600 may be omitted, that is, a three-segment structure is formed by the first supporting member 100, the base 300, and the second supporting member 200.

[0123] The hinge structure can be a hinge structure for an outward-folding electronic device. The base 300 may have a target support surface, the first support member 100 has a first support surface on the side opposite to the first mating member 410, and the second support member 200 has a second support surface on the side opposite to the second mating member 420.

[0124] In the first relative position, the first support surface, the target support surface, and the second support surface constitute the first support surface for supporting the arc-shaped structure; in the second relative position, the first support surface, the target support surface, and the second support surface constitute the second support surface for supporting the planar structure.

[0125] It is also possible to make the hinge structure of an electronic device with an inwardly bent hinge structure.

[0126] This application also provides an electronic device, which may include a first body, a second body, and a hinge structure movably connecting the first body and the second body. The first body has a first surface, and the second body has a second surface. The hinge structure allows the first body and the second body to switch between a first posture and a second posture. In the first posture, the angle between the first body and the second body can be 0° or approximately 0° (e.g., 1° or 3°); in the second posture, the angle between the first body and the second body can be 180° or approximately 180° (e.g., 179° or 182°).

[0127] The rotating shaft structure includes a base 300, a first support component 100, a second support component 200, and a movable connecting assembly 400.

[0128] The base 300 has a first guide structure 301 and a second guide structure 302, and the first guide structure 301 and the second guide structure 302 have an intersecting area;

[0129] The first support member 100 is movable relative to the base 300.

[0130] The second support member 200 is movable relative to the base 300;

[0131] The movable connection assembly 400 includes a first mating member 410 connecting the base 300 and the first support member 100, and a second mating member 420 connecting the base 300 and the second support member 200. The first mating member 410 is movable along the first guide structure 301 and the second mating member 420 is movable along the second guide structure 302, so that the first support member 100 and the second support member 200 can switch between a first relative position and a second relative position.

[0132] in,

[0133] In the first relative position, the base 300, the first support member 100 and the second support member 200 form a first support structure so that the first body and the second body are in a first posture, the first part 411 of the first mating member 410 and the second part 421 of the second mating member 420 are located in the intersecting area, and along the extension direction of the base 300, the projections of the first part 411 and the second part 421 at least partially overlap.

[0134] In the second relative position, the base 300, the first support member 100 and the second support member 200 form a second support structure so that the first body and the second body are in a second posture, and the first support structure is different from the second support structure.

[0135] The electronic device may further include a flexible screen, which may have a first screen portion, a second screen portion, and an intermediate flexible bending portion connecting the first screen portion and the second screen portion. The first screen portion may be connected to a first surface of a first body, the second screen portion may be connected to a second surface of a second body, and the intermediate flexible bending portion is supported by a support structure (a first support structure and a second support structure) to form different support structures.

[0136] In embodiments where the electronic device is a foldable phone or foldable computer, in the first relative position, the first surface of the first body is opposite to the second surface of the second body, and the first support structure forms an outwardly convex structure for supporting the convex arc surface.
