Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to a reset component, a rotating shaft mechanism, and an electronic device. Background Art

[0003] With the continuous development of technology, electronic devices, such as mobile phones, are gradually developing into foldable phones, so that mobile phones can have large screens and convenient functions at the same time. The shell assembly of a foldable phone includes two parts, which are connected by a hinge mechanism. The flexible display of the foldable phone is respectively connected to the two parts of the shell assembly. In this way, the flexible display is deformed by the two parts of the shell assembly, thereby flattening or folding the flexible display of the foldable phone. In order to avoid interference between the shell assembly during rotation, a gap is provided between the flexible display and the shell assembly at both ends of the hinge mechanism in the longitudinal direction. In order to cover this gap and prevent the ends of the hinge mechanism from being exposed, protective deformable parts are provided at both ends of the hinge mechanism in the longitudinal direction. This not only ensures the appearance effect, but also reduces the possibility of liquids, dust and other substances entering the gap during use. However, the deformable parts are prone to bending, accumulation or falling out during use, thereby affecting the user experience.

[0004] Summary of the Invention

[0005] The present application provides a reset assembly, a rotating shaft mechanism, and an electronic device to solve the problem that deformable parts are prone to bending, accumulation, or falling out during use.

[0006] The technical solution is as follows:

[0007] In a first aspect, the present application provides a reset assembly comprising a deformable member and a push-pull structure, wherein the push-pull structure is configured to enable the deformable member to move along its length direction during the unfolding process of the flexible display screen of the electronic device so as to flatten the deformable member;

[0008] In which, the push-pull structure includes a first mating part and a second mating part, the first mating part is fixed to the deformable part, and the second mating part is used to be installed on the hinge mechanism of the electronic device; the second mating part is configured to be able to contact the first mating part during the unfolding process of the flexible display screen to drive the first mating part and the deformable part to move together.

[0009] By adopting the above solution, after the reset assembly is applied to the electronic device, the deformable member is arranged at the edge of the flexible display screen, and the deformable member is used to cover the end of the hinge mechanism. During the unfolding process of the flexible display screen, the second mating member contacts the first mating member, driving the first mating member and the deformable member to move together, so that the deformable member is flattened and reset, thereby reducing the accumulation or disengagement of the deformable member and improving the user experience.

[0010] In some implementations, the first mating part is a clamping platform, and the second mating part is a clamping claw.

[0011] By adopting the above solution and utilizing the cooperation between the clamping platform and the clamping claw, the success rate of the second matching piece contacting the first matching piece can be improved, thereby facilitating the reduction of the accumulation or disengagement of the deformed piece.

[0012] In some implementations, the clamping platform has a first abutting surface, which is arranged at an angle to the surface of the deformable member; the clamping claw can abut against the first abutting surface to drive the clamping platform to move.

[0013] By adopting the above solution, the success rate of the second matching piece contacting with the first matching piece is improved.

[0014] In some implementations, the angle formed between the first abutting surface and the surface of the deformable member is an acute angle;

[0015] An opening of an angle formed between the first abutting surface and a surface of the deformable member faces the clamping claw, so that the clamping claw can abut against the first abutting surface.

[0016] By adopting the above solution, the success rate of the second matching piece contacting with the first matching piece is improved.

[0017] In some implementations, there are multiple first mating parts, and the multiple first mating parts are spaced apart along the length direction of the deformable part.

[0018] By adopting the above solution, multiple first matching pieces are provided to realize a redundant design, that is, when the second matching piece is not in contact with the corresponding first matching piece, the second matching piece can match with one of the remaining first matching pieces, thereby realizing the flattening and resetting of the deformed piece.

[0019] In some implementations, there are two push-pull structures, and the two push-pull structures are symmetrically arranged about a first symmetry axis, the first symmetry axis is parallel to the width direction of the deformable member, and the first symmetry axis is located at the midpoint of the length of the deformable member.

[0020] By adopting the above solution and providing two push-pull mechanisms, the deformable members at different positions can be flattened and reset, that is, the two ends of the deformable member can be flattened and reset.

[0021] In some implementations, the reset assembly further includes a limiting structure, and the limiting structure is used to enable the end portion of the deformable member in the longitudinal direction to move within a limited range.

[0022] By adopting the above solution, the possibility of the end of the deformable part falling out can be reduced by using the limiting structure. In this way, the limiting structure and the push-pull structure realize the double insurance of flattening and resetting the deformable part, thereby reducing the accumulation or falling out of the deformable part and improving the user experience.

[0023] In some implementations, the limiting structure includes a limiting platform provided on the deformable member, and a limiting slot provided on the housing of the electronic device, wherein the limiting platform extends into the limiting slot;

[0024] Or / and, the limiting structure includes a limiting groove provided on the deformable member, and a limiting platform provided on the housing of the electronic device, and the limiting platform extends into the limiting groove.

[0025] By adopting the above solution, the end of the deformable member can be better restricted through the cooperation between the limiting platform and the limiting groove, thereby reducing the possibility of the deformable member coming out.

[0026] In some implementations, the limiting structure and the push-pull structure are respectively located on two opposite sides of the deformable member.

[0027] By adopting the above solution, the limiting structure and the push-pull structure are respectively arranged on both sides of the deformable member, which can reduce or avoid interference between the limiting structure and the push-pull structure.

[0028] In some implementations, the reset assembly further includes a support frame fixedly connected to a middle portion of the deformable member in a longitudinal direction.

[0029] By adopting the above solution, the support frame can fix the middle part of the deformable member, so that the deformable member is divided into two movable sub-segments, and the sub-segments with different push-pull structures are flattened and reset.

[0030] In some implementations, the support frame includes a clamping portion and a fixing portion, the clamping portion is connected to the fixing portion; and the deformable member is fixed in a clamping space of the clamping portion.

[0031] By adopting the above solution, the fixing portion can be connected to the rotating shaft mechanism of the electronic device, and the clamping portion can facilitate the fixation of the middle portion of the deformable member.

[0032] In some implementations, the deformable member has a first through hole, and the clamping space of the clamping portion has a positioning column, and the positioning column is disposed in the first through hole.

[0033] By adopting the above solution and inserting the positioning post into the first through hole, the middle portion of the deformable member can be better fixed, thereby improving the stability of the connection between the deformable member and the support frame.

[0034] In some implementations, the deformable member is bonded and fixed to the clamping portion.

[0035] By adopting the above solution, the stability of the connection between the deformable member and the clamping portion can be improved by bonding.

[0037] By adopting the above solution, after the reset assembly is applied to the rotating shaft mechanism, it is helpful to reduce the accumulation or disengagement of deformed parts, thereby improving the user experience.

[0064] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0065] It should be understood that the “multiple” mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, “ / ” means or, for example, A / B can mean A or B; “and / or” in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of this application, words such as “first” and “second” are used to distinguish between identical or similar items with basically the same functions and effects. Those skilled in the art can understand that words such as “first” and “second” do not limit the quantity and execution order, and words such as “first” and “second” do not necessarily limit them to be different.

[0066] As shown in Figures 1 and 2, in the related art, there is a gap between the shell component 10 of the electronic device and the edge of the display screen 11. In order to cover the gap, a structural member 12 is provided, and the structural member 12 can also be called a small A shell. In order to avoid interference between the shell component 10 during rotation, a gap is provided between the display screen 11 and the shell component 10 at both ends of the length direction of the hinge mechanism. In order to cover the gap and avoid exposure of the end of the hinge mechanism, a deformable member 13 with a protective function is provided at both ends of the length direction of the hinge mechanism. The deformable member 13 is located between the structural member 12 and the display screen 11. This not only ensures the appearance effect, but also reduces the possibility of liquid, dust and other substances entering the gap during use. However, the deformable member 13 is prone to bending, accumulation or falling out during use, thereby affecting the user experience. FIG2 shows the phenomenon that the deformable member 13 accumulates when the electronic device is in the unfolded state, and FIG3 shows the phenomenon that the deformable member 13 falls out when the electronic device is in the unfolded state. In order to reduce the phenomenon of the deformable member 13 accumulating or falling out, some methods have been proposed, such as: by reducing the gap between the structural member 12 and the display screen 11, increasing the contact pressure of the deformable member 13 with the structural member 12 and the display screen 11 respectively, and reducing the risk of the deformable member 13 falling out; or, by adjusting the relative position of the deformable member 13 and the structural member 12, so that the deformable member 13 is in a position that is not easy to fall out during movement, so as to reduce the risk of the deformable member 13 falling out; or, using a deformable member 13 made of a material with greater strength, and setting a vertical surface on the side of the deformable member 13 to support the shell assembly 10, so as to reduce the risk of the deformable member 13 falling out; but when the above methods are actually used, there is still a high probability that the deformable member 13 will fall out or accumulate.

[0067] To this end, embodiments of the present application provide a reset component, a rotating shaft mechanism, and an electronic device to solve the above-mentioned problems. The reset component, the rotating shaft mechanism, and the electronic device provided in embodiments of the present application are explained in detail below.

[0068] In one or more embodiments, the reset assembly provided by the present application can be applied to the hinge mechanism 200 of a foldable electronic device, and of course can also be applied to other application scenarios that require the use of a deformable member 101.

[0069] As shown in FIG3 , in some embodiments, the reset assembly includes a deformable member 101 and a push-pull structure. The deformable member 101 provides a protective covering function, preventing the end of the hinge mechanism 200 shown in FIG21 from being exposed. This not only maintains the appearance but also reduces the possibility of liquids, dust, and other substances entering the gap during use. Therefore, the reset assembly not only has a protective covering function but also serves to flatten the deformable member 101 during the unfolding of the flexible display 304. The push-pull structure achieves the flattening of the deformable member 101 by pushing and pulling. The push-pull structure is configured to enable the deformable member 101 to move along its own length direction during the unfolding process of the flexible display screen 304 of the electronic device, so as to flatten the deformable member 101; the push-pull structure includes a first mating member 102 and a second mating member 103, the first mating member 102 is fixed to the deformable member 101, and the second mating member 103 is used to be installed on the hinge mechanism 200 of the electronic device; the second mating member 103 is configured to be able to contact the first mating member 102 during the unfolding process of the flexible display screen 304, so as to drive the first mating member 102 and the deformable member 101 to move together.

[0070] In at least one embodiment of the present application, after the reset component is applied to the electronic device, the deformable member 101 is arranged at the edge of the flexible display screen 304, and the deformable member 101 is used to cover the end of the hinge mechanism 200. During the unfolding process of the flexible display screen 304, the second mating member 103 contacts the first mating member 102, driving the first mating member 102 and the deformable member 101 to move together, so that the deformable member 101 is flattened and reset, thereby reducing the accumulation or disengagement of the deformable member 101 and improving the user experience.

[0071] In some embodiments, the deformable member 101 is generally a flexible structure that is flexible and deformable. The material of the deformable member 101 may be polyethylene terephthalate or polytetrafluoroethylene. The deformable member 101 is strip-shaped and has a membrane or sheet-like structure. That is, the deformable member 101 has two opposing surfaces, namely a first surface 104 and a second surface 105. The length of the deformable member 101 is generally perpendicular to the length of the hinge mechanism 200, or in other words, perpendicular to the fold of the flexible display 304. After the second mating member 103 contacts the first mating member 102, the second mating member 103 applies force to the first mating member 102 to push the first mating member 102 to move, thereby pulling the deformable member 101, causing the deformable member 101 to gradually flatten as the flexible display 304 unfolds. After the display is fully unfolded, the deformable member 101 is completely flattened.

[0072] As shown in conjunction with Figures 3, 4, 7, and 8, in some embodiments, the first mating member 102 is a latching platform, and the second mating member 103 is a claw. The latching platform and the claw cooperate to improve the success rate of contact between the second mating member 103 and the first mating member 102, thereby reducing the accumulation or dislodgment of the deformable member 101. In one embodiment, the claw can be in the form of a ratchet, which facilitates a higher success rate of engagement between the claw and the latching platform. Compared to related art solutions that use a deformable member made of a relatively strong material and provide a vertical surface on the side of the deformable member to support the housing assembly, which increases the thickness of the entire device and also increases the length of the entire device, the reset assembly in the embodiments of the present application improves the deformable member 101 by adding the first mating member 102 to the deformable member 101 and utilizing a snap-fit ​​fit between the second mating member 103 and the first mating member 102 to reset the deformable member 101, thereby preventing an increase in the thickness or length of the entire device.

[0073] It should be noted that the clamping claw can also be in the form of a pointed structure; the clamping claw and the clamping platform can be in a low-pair fit or a high-pair fit.

[0074] As shown in Figures 7, 8, and 11, in some embodiments, the platform has a first abutment surface 106, which is set at an angle to the surface of the deformable member 101. The claw can abut against the first abutment surface 106 to drive the platform to move, thereby driving the deformable member 101 to move together. This arrangement helps to improve the success rate of contact between the second mating member 103 and the first mating member 102. In one embodiment, the push-pull structure is located on the side of the first surface 104 of the deformable member 101, and the platform is located on the first surface 104 of the deformable member 101. The platform protrudes from the first surface 104, and the first surface 104 is positioned toward the claw. The first abutment surface 106 of the platform is set at an angle to the first surface 104.

[0075] It should be noted that, in some other possible implementations, a groove may be provided on the first surface 104 , and the clamping platform is a structure formed by combining the groove bottom and groove wall of the groove.

[0076] As shown in conjunction with Figures 8 and 11 , in some embodiments, the angle formed between the first abutting surface 106 and the surface of the deformable member 101 is acute; the opening 107 at the angle formed between the first abutting surface 106 and the surface of the deformable member 101 faces the latch, allowing the latch to abut against the first abutting surface 106, further improving the success rate of contact between the second mating member 103 and the first mating member 102. In one embodiment, the angle formed between the first abutting surface 106 and the first surface 104 of the deformable member 101 is acute, so that the latching platform is in the form of ratchet teeth, facilitating the engagement of the latching claw; after the deformable member 101 is installed in the electronic device, the opening 107 at the angle formed between the first abutting surface 106 and the surface of the deformable member 101 faces the fold of the display screen, thus facilitating the engagement of the latching claw and the latching platform.

[0077] As shown in conjunction with Figures 3 and 5 , in some embodiments, there are multiple first mating members 102, and the multiple first mating members 102 are spaced apart along the length of the deformable member 101. By providing multiple first mating members 102, a redundant design is achieved, namely: when the second mating member 103 is not in contact with the corresponding first mating member 102, the second mating member 103 can mate with one of the remaining first mating members 102, thereby flattening and resetting the deformable member 101. In one embodiment, the spacing between two adjacent first mating members 102 in the multiple first mating members 102 is equal, and the claw is located between two adjacent first mating members 102 in the multiple first mating members. In this way, the opening 107 of the first abutting surface 106 of at least one clamping platform faces the claw, thereby achieving abutment of the claw against the clamping platform, and the claw drives the clamping platform and the deformable member 101 to move together, thereby flattening the deformable member 101.

[0078] It should be noted that, in some other possible implementations, the distance between two adjacent first matching members 102 may also be in the form of an arithmetic progression, which can of course be determined according to actual conditions.

[0079] In some embodiments, there are two push-pull structures, symmetrically arranged about a first axis of symmetry. The first axis of symmetry is parallel to the width of the deformable member 101 and is located at the midpoint of the length of the deformable member 101. This arrangement of two push-pull mechanisms allows the deformable member 101 to be flattened and reset at different positions, i.e., flattened and reset at both ends of the length of the deformable member 101. In one embodiment, the middle of the length of the deformable member 101 is fixed, resulting in one fixed point. The deformable member 101 is divided into two sub-segments of equal length, each of which corresponds to a push-pull structure. Furthermore, since the middle of the deformable member 101 is fixed, each sub-segment has a freely movable end, and each sub-segment can be flattened under the action of the push-pull structure.

[0080] It should be noted that in some other possible embodiments, after the deformable member 101 is fixed, the lengths of the two sub-segments may not be equal. In this case, the two push-pull structures may not be symmetrically arranged. Furthermore, in some other possible embodiments, after the deformable member 101 is fixed, it may be divided into three or four segments, etc., depending on the number of fixing points. That is, if there are two fixing points, the deformable member 101 is divided into three sub-segments; if there are three fixing points, the deformable member 101 is divided into four sub-segments. Each sub-segment may correspond to a push-pull structure, which is responsible for flattening each sub-segment.

[0081] In some embodiments, the reset assembly further includes a limiting structure configured to limit the movement of the longitudinal ends of the deformable member 101 within a limited range. This limiting range of movement of the ends of the deformable member 101 reduces the possibility of the ends of the deformable member 101 coming out of the device. The limiting structure and the push-pull structure provide a dual safeguard for flattening and restoring the deformable member 101, thereby reducing the possibility of the deformable member 101 accumulating or coming out of the device and improving the user experience. The limiting structure can limit the movement range of the end of the deformable member 101 in the length direction of the deformable member 101, or / and limit the activity range of the deformable member 101 in the width direction, thereby realizing two-way limitation of the deformable member 101, which is beneficial to reducing the phenomenon of the deformable member 101 falling out or stacking; and when the limiting structure limits the movement range of the deformable member 101 in the length direction and the activity range in the width direction at the same time, it is beneficial to avoid the phenomenon of the deformable member 101 falling out and stacking. The limiting structure limits the activity range in the width direction of the deformable member 101 mainly to ensure that the deformable member 101 can move along the length direction, and avoid or reduce the movement or shaking of the deformable member 101 in its own width direction.

[0082] It should be noted that the limiting structures primarily limit the longitudinal ends of the deformable member 101. Therefore, if the deformable member 101 has two ends, the number of limiting structures is two. Of course, in some other possible implementations, the number of limiting structures may not only limit the range of movement of the ends of the deformable member 101 in the longitudinal and width directions, but may also limit the range of movement of the portion between the free end and the fixed end of the sub-segment of the deformable member 101 in the longitudinal and width directions. Specifically, the fixed end of the sub-segment is fixed, while the free end of the sub-segment is movable.

[0083] In some embodiments, the limiting structure includes a limiting platform 108 provided on the deformable member 101, and a limiting groove 109 provided on the housing of the electronic device, and the limiting platform 108 extends into the limiting groove 109; or / and, the limiting structure includes a limiting groove 109 provided on the deformable member 101, and a limiting platform 108 provided on the housing of the electronic device, and the limiting platform 108 extends into the limiting groove 109; in this way, through the cooperation between the limiting platform 108 and the limiting groove 109, the end of the deformable member 101 can be better restricted, thereby reducing the possibility of the deformable member 101 falling out.

[0084] As shown in Figures 3, 4, 11 and 15, in one embodiment, the bottom of the limiting groove 109 is surrounded by a groove wall, which is equivalent to the outline of the groove opening of the limiting groove 109 being a closed figure. In this way, the range of movement of the deformable member 101 in the length direction and the range of activity in the width direction can be limited, which is conducive to avoiding or reducing the movement or shaking of the deformable member 101 in its own width direction. The limiting structure includes a limiting platform 108 and a limiting groove 109. The limiting platform 108 is provided on the deformable member 101, and the limiting groove 109 is provided on the housing of the electronic device. The limiting platform 108 extends into the limiting groove 109. The limiting platform 108 can be a tooth-like structure. Exemplarily, the limiting platform 108 is in the form of a ratchet, which is conducive to matching with the limiting groove 109.

[0085] It should be noted that, in some other possible implementations, a limit groove 109 may be provided on the deformable member 101, and a limit platform 108 may be provided on the housing of the electronic device; in some other possible implementations, the limit platform 108 and the limit groove 109 may be provided on the deformable member 101, and the limit platform 108 and the limit groove 109 may be provided on the housing of the electronic device, so that the limit platform 108 on the deformable member 101 cooperates with the limit groove 109 on the housing, and the limit groove 109 of the deformable member 101 cooperates with the limit platform 108 on the housing.

[0086] In some embodiments, the limiting structure and the push-pull structure are located on opposite sides of the deformable member 101. Separating the limiting structure and the push-pull structure on opposite sides of the deformable member 101 can reduce or avoid interference between the limiting structure and the push-pull structure. Referring to Figures 4, 7, and 11, in one embodiment, the push-pull structure is located on the side of the first surface 104 of the deformable member 101, and the limiting structure is located on the side of the second surface 105 of the deformable member 101. The limiting platform 108 is located on the second surface 105 of the deformable member 101, with the limiting groove 109 facing the second surface 105 so that the limiting platform 108 can extend into the limiting groove 109.

[0087] As shown in Figure 3, in some embodiments, the reset assembly also includes a support frame 110, which is fixedly connected to the middle part of the deformable member 101 in the longitudinal direction, so that the deformable member 101 is divided into two movable sub-segments, and the push-pull structure flattens and resets the different sub-segments; after the support frame 110 fixes the middle part of the deformable member 101, and when the number of fixed points is one, the deformable member 101 is divided into two different sub-segments, each sub-segment has a free end, the push-pull structure flattens each sub-segment, and the limiting structure limits the range of motion of each sub-segment.

[0088] It should be noted that, in some other possible embodiments, the support frame 110 can also be fixed at a non-central position of the deformable member 101, so that the deformable member 101 can be divided into two sub-segments of different lengths; in addition, the number of support frames 110 can also be two or more. Specifically, the number of support frames 110 is related to the number of sub-segments into which the deformable member 101 is divided. For example, when the deformable member 101 is divided into three sub-segments, the number of support frames 110 is two.

[0089] As shown in FIG9 , in some embodiments, the support frame 110 includes a clamping portion 111 and a fixing portion 112 . The clamping portion 111 is connected to the fixing portion 112 . The deformable member 101 is fixed in a clamping space 115 of the clamping portion 111 . This allows the fixing portion 112 to connect to the hinge mechanism 200 of the electronic device, while the clamping portion 111 facilitates securing the middle portion of the deformable member 101 . As shown in FIG6 , in one embodiment, the deformable member 101 has a notch 113 in the width direction. The notch 113 is located in the middle of the length of the deformable member 101 . This arrangement allows the support frame 110 to have a width equal to the maximum width of the deformable member 101 after mating with the deformable member 101 , thereby reducing the width of the overall reset assembly along the width direction of the deformable member 101 .

[0090] 6 and 9 , in some embodiments, the deformable member 101 has a first through hole 114, and the clamping space 115 of the clamping portion 111 has a positioning column 116, which is passed through the first through hole 114. In this way, by inserting the positioning column 116 into the first through hole 114, the middle part of the deformable member 101 can be better fixed, thereby improving the stability of the connection between the deformable member 101 and the support frame 110. As shown in Figures 4, 7, and 9, in one embodiment, the clamping portion 111 includes a first sub-portion 117 and a second sub-portion 118. The first sub-portion 117 and the second sub-portion 118 are respectively connected to the fixing portion 112. The first sub-portion 117 and the second sub-portion 118 are spaced apart to form a clamping space 115. The first sub-portion 117 is opposite to the second surface 105, and the second sub-portion 118 is opposite to the first surface 104. The clamping portion 111 and the fixing portion 112 can be an integral structure, which is convenient for processing and manufacturing and reduces the number of parts. The fixing portion 112 can be a plate-like structure, which facilitates the connection between the fixing portion 112 and the rotating shaft mechanism 200 of the electronic device. The fixing portion 112 can be connected to the rotating shaft mechanism 200 of the electronic device by screws, bonding, or interference fit.

[0091] It should be noted that, in some other possible implementations, the support frame 110 may also be a part of the hinge mechanism 200 of the electronic device, which further helps to reduce the number of parts.

[0092] In some embodiments, the deformable member 101 is bonded to the clamping portion 111, and this bonding can improve the stability of the connection between the deformable member 101 and the clamping portion 111. As shown in Figures 5 and 9 , the deformable member 101 and the clamping portion 111 are bonded together, for example, by adhesive 119. The first surface 104 and the first sub-portion 117 are bonded together by adhesive 119; the second surface 105 and the second sub-portion 118 are also bonded together by adhesive 119. This bonding improves the stability of the connection between the deformable member 101 and the clamping portion 111.

[0093] In one or more embodiments, as shown in FIG. 21 and FIG. 11 , the present application further provides a hinge mechanism 200, which includes a door panel, a base, and a reset assembly provided in any embodiment. The door panel is configured to rotate relative to the base; a second mating member 103 is mounted on the door panel, and the second mating member 103 can move closer to or further away from the first mating member 102 as the door panel rotates. Compared to the related art, in which, during the unfolding process of an electronic device, the deformable member may not be able to return to its initial position, and its excess portion may easily accumulate on the outside of the structural member, requiring manual restoration, the reset assembly provided in the embodiment of the present application utilizes the relative movement between the door panel and the deformable member 101 of the electronic device to achieve contact between the second mating member 103 on the door panel and the first mating member 102 on the deformable member 101, thereby pulling the deformable member 101 back during the unfolding process of the electronic device to prevent accumulation and disengagement of the deformable member 101. In addition, during the folding process of the electronic device, the first mating member 102 and the second mating member 103 can separate, thereby facilitating the movement of the deformable member 101.

[0094] As shown in FIG. 20 , in some embodiments, the hinge mechanism 200 includes two door panels, namely a first door panel 201 and a second door panel 202. The hinge mechanism 200 also includes a first connector and a second connector, wherein the first door panel 201 is rotationally connected to the first connector, and the second door panel 202 is rotationally connected to the second connector. The hinge mechanism 200 also includes a first swing arm and a second swing arm. The connection between the first swing arm and the first connector can be a sliding connection or a rotational connection, or the first swing arm and the first connector can be in high-pair contact. The connection between the second swing arm and the second connector can be a sliding connection or a rotational connection, or the second swing arm and the second connector can be in high-pair contact. The first swing arm is rotationally connected to the base, and the second swing arm is rotationally connected to the base. In one embodiment, the reset assembly comprises two push-pull structures and two position-limiting structures. The second mating member 103 of one push-pull structure is fixed to the first door panel 201, while the second mating member 103 of the other push-pull structure is fixed to the second door panel 202. A reset assembly can be provided at each end of the shaft mechanism 200 in the longitudinal direction. The support frame 110 of the reset assembly is fixed to the base.

[0095] It should be noted that, in some other possible embodiments, the rotating shaft mechanism 200 further includes a shaft cover, which is used to wrap the base to prevent the base from being exposed, thereby ensuring a better appearance; and the support of the reset component can also be fixed on the shaft cover; or, the support frame 110 is connected to the base and the shaft cover respectively.

[0096] As shown in Figures 20 and 21 , in one or more embodiments, the present application further provides an electronic device comprising a housing and the hinge mechanism 200 provided in any embodiment. The housing comprises a first sub-housing 301 and a second sub-housing 302, each of which is rotatably connected to the hinge mechanism 200. This helps reduce the accumulation or dislodgment of the deformable member 101 when the reset assembly is applied to the electronic device, thereby improving the user experience.

[0097] In some embodiments, the electronic device can be a foldable electronic device. For example, the electronic device can be a mobile phone, a tablet computer, a notebook, or an e-reader. Taking the mobile phone as an example, the first sub-shell 301 is fixedly connected to the first connecting member, and the second sub-shell 302 is fixedly connected to the second connecting member. In this way, when the hinge mechanism 200 rotates, the first sub-shell 301 and the second sub-shell 302 rotate relative to each other, thereby realizing the unfolding or folding of the foldable electronic device. The first sub-shell 301 and the second sub-shell 302 can be the middle frame of the mobile phone. In addition, when the hinge mechanism 200 rotates, the first door panel 201 and the second door panel 202 are also rotated relative to the base. The first door panel 201 can also rotate relative to the first sub-shell 301, and the second door panel 202 can also rotate relative to the second sub-shell 302. It should be noted that the folding method of the mobile phone is not limited to the horizontal folding method and the vertical folding method.

[0098] As shown in Figure 20 , in some embodiments, the electronic device further includes a flexible display 304, and the housing further includes a structural member 303. The first sub-shell 301 and the second sub-shell 302 are respectively connected to the flexible display 304. As shown in Figures 13 , 14 , and 15 , the structural member 303 is disposed at the edge of the flexible display 304 and is a strip-shaped structure. The deformable member 101 is located in the gap formed between the flexible display 304 and the structural member 303. The first mating member 102 is located on the side of the deformable member 101 facing the flexible display 304; this facilitates contact between the second mating member 103 and the first mating member 102. When the first sub-shell 301 and the second sub-shell 302 rotate relative to each other, they drive the portions of the flexible display 304 connected thereto, thereby expanding or folding the entire flexible display 304 and, consequently, expanding or folding the electronic device. The structural member 303 is disposed along the edge of the flexible display screen 304; the structural member 303 is fixed to the first sub-shell 301, and the structural member 303 is fixed to the second sub-shell 302. After the support frame 110 of the reset assembly is fixed to the base, as shown in Figures 3 and 11, the deformable member 101 is divided into two sub-segments, for example, a first sub-segment 120 and a second sub-segment 121. The opening 107 at the angle formed by the first abutting surface 106 on the first sub-segment 120 and the surface of the deformable member 101 is disposed opposite the opening 107 at the angle formed by the first abutting surface 106 on the second sub-segment 121 and the surface of the deformable member 101. As shown in Figures 3, 10 and 17, the first sub-segment 120 of the deformable member 101 is located in the gap between the flexible display screen 304 and the structural member 303 on the first sub-shell 301, and the second mating member 103 of the push-pull structure corresponding to the first sub-segment 120 is fixed on the first door panel 201; as shown in Figures 3 and 20, the second sub-segment 121 of the deformable member 101 is located in the gap between the flexible display screen 304 and the structure on the second sub-shell 302, and the second mating member 103 of the push-pull structure corresponding to the second sub-segment 121 is fixed on the second door panel 202.During the unfolding of the electronic device, the first door panel 201 rotates relative to the first sub-shell 301. When the second mating piece 103 on the first door panel 201 contacts the corresponding first mating piece 102, the first mating piece 102 and the first sub-segment 120 are driven to move to achieve the flattening of the first sub-segment 120. The second door panel 202 rotates relative to the second sub-shell 302. When the second mating piece 103 on the second door panel 202 contacts the corresponding first mating piece 102, the first mating piece 102 and the second sub-segment 121 are driven to move to achieve the flattening of the second sub-segment 121. The present application provides a push-pull structure for resetting between the deformable member 101 and the door panel, and utilizes the first mating piece 102 and the second mating piece 103 to cooperate to form a snap mechanism. During the unfolding of the foldable electronic device, the second mating piece 103 clamps the first mating piece 102 to achieve the resetting movement of the deformable member 101, thereby preventing the deformable member 101 from falling out or accumulating on the outside of the structural member 303.

[0099] In some embodiments, the length of the clamping platform extends along the width of the deformable member 101, and the length of the clamping platform is adapted to the clamping claw. Because a portion of the deformable member 101 is located between the flexible display 304 and the structural member 303, the length of the clamping platform needs to be appropriately set. The clamping platform can be configured so that it does not extend into the gap formed between the structural member 303 and the flexible display 304. This helps ensure the movement of the deformable member 101 between the flexible display 304 and the structural member 303.

[0100] 15 and 16 , in some embodiments, the limiting groove 109 in the limiting structure can be provided on the structural member 303, and the limiting platform 108 can also be provided on the structural member 303. For example, the limiting groove 109 is provided on the structure, while the limiting platform 108 cooperating with the limiting groove 109 is provided on the deformable member 101, that is, on the second surface 105 of the deformable member 101. In this way, the cooperation between the limiting platform 108 and the limiting groove 109 can effectively limit the end of the deformable member 101, thereby reducing the possibility of the deformable member 101 falling out. In one embodiment, the length direction of the limit platform 108 extends along the width of the deformable member 101, and the length direction of the limit platform 108 is parallel to the width direction of the limit groove 109. Since a part of the structure of the deformable member 101 is located between the flexible display screen 304 and the structural member 303, the length of the limit platform 108 needs to be appropriately set. The limit platform 108 can be set so as not to extend into the gap formed between the structural member 303 and the flexible display screen 304, which is conducive to ensuring the movement of the deformable member 101 between the flexible display screen 304 and the structural member 303.

[0101] The working principle of the reset component in the embodiment of the present application after being applied to the electronic device is as follows:

[0102] As shown in Figures 3, 18, and 19, the first and second sub-segments 120, 121 of the deformable member 101 are respectively mounted at corresponding positions on the electronic device, positioned between the flexible display 304 and the structural member 303, ensuring that the deformable member 101 can move between the flexible display 304 and the structural member 303. The portion of the first mating member 102 on the first surface 104 of the deformable member 101 that protrudes between the flexible display 304 and the housing mates with the second mating member 103 on the door panel. During folding of the electronic device, the door panel moves away from the structural member 303, and the second mating member 103 separates from the first mating member 102, ensuring that the deformable member 101 can be pulled out with the movement of the hinge mechanism 200. As shown in Figure 12, during unfolding of the electronic device, the second mating member 103 and the first mating member 102 form a snap mechanism that pulls the deformable member 101 back with the movement of the door panel, achieving automatic flattening and repositioning of the deformable member 101 and preventing the deformable member 101 from slipping out and accumulating. In addition, the limit platform 108 on the second surface 105 of the deformable member 101 cooperates with the upper limit groove 109 on the structural member 303. When the electronic device is folded, the limit platform 108 hooks the end of the limit groove 109 to prevent the deformable member 101 from sliding out, thereby solving the problem of the deformable member 101 falling out.
