In recent years, with the continuous development of screen technology, a screen of a terminal device such as a mobile phone can not only be a flat screen, but also be any flexible screen which can be bent. Thus, the terminal equipment such as a mobile phone and the like can be made into a foldable form, and the terminal can be folded once or for many times when the terminal equipment is carried or only needs a smaller screen; the terminal may be unfolded when a larger screen is required. Therefore, the foldable terminal can be flexibly switched to different modes according to different use scenes.

Foldable terminals may include, but are not limited to, folding screen devices that are cell phones, tablet computers, notebook computers, electronic book readers, wearable devices (e.g., virtual Reality (VR) glasses, smart watches, smart bracelets, head mounted displays, etc.), wireless U-discs, bluetooth sound/headphones, automobile recorders, etc.

For convenience of explanation, the following embodiments will take a foldable mobile phone as an example of a foldable terminal according to an embodiment of the present application.

Fig. 1 is a schematic structural diagram of a foldable mobile phone in an unfolded state in the related art, and fig. 2 is a schematic structural diagram of the foldable mobile phone in a folded state shown in fig. 1. As shown in fig. 1 to 4, a foldable cellular phone includes a supporting device 100 and a flexible display 300 provided on the supporting device 100. The support device 100 includes a frame 110, a shaft cover 120, and a shaft structure 130. The frame 110 is generally provided with more than two frames, and two adjacent frames 110 are rotatably connected with the same shaft cover 120 through a rotating shaft structure 130. The end portions of the two adjacent frames 110, which are close to the rotating shaft structure 130, can rotate around the rotating shaft between the two frames 110, so that the ends of the two frames 110, which are far away from the rotating shaft structure 130, are relatively close to or relatively far away from each other, and the foldable mobile phone can correspondingly present different states such as folding or unfolding. The flexible display screen 300 covers one surface of the supporting device 100, and may be folded or unfolded according to the position change between the adjacent frames 110. Specifically, when the foldable mobile phone includes two frames 110, the two frames 110 are in the unfolded positions, and when the foldable mobile phone is in the unfolded state, the two frames 110 are parallel and coplanar. Accordingly, the flexible display 300 covering the surface of the frame 110 may form a larger display surface in the unfolded state, and the display surface may be displayed as a separate display screen, as shown in fig. 1. When the two frames 110 are respectively in the folded positions, the foldable mobile phone is in a folded state, at this time, one ends of the two frames 110 far away from the rotating shaft structure 130 are in contact with each other, and the flexible display screen 300 is folded, as shown in fig. 2.

It should be noted that, the number of the frames 110 of the foldable mobile phone may be two or more, and when the number of the frames 110 is two or more, each adjacent frame 110 may rotate around the axes of rotation parallel to each other, so as to form a multi-layer folded structure, or be unfolded to obtain a larger display area. In this application, a foldable mobile phone having two housings 110 will be mainly described as an example.

As shown in fig. 5, the pivot structure 130 generally includes a swing arm base 131, a main swing arm 132, a sub-swing arm 133, a damping member 134, and a connection member. The swing arm base 131 is generally fixedly mounted to the shaft cover 120. One end of the main swing arm 132 is in rotational contact with the swing arm base 131, and the other end is rotatably connected with the frame 110. Thus, when a user applies force to any one of the housings 110, the housing 110 is folded or unfolded with respect to the shaft cover 120 by the external force of the user. The damping member 134 is disposed on the swing arm base 131 and located in the shaft cover 120, and may be a cam spring damping member 134, a gear damping member 134, or the like, which is not limited in the embodiment of the present application. The auxiliary swing arm 133 is arranged in parallel with the main swing arm 132, one end of the auxiliary swing arm is rotatably connected with the swing arm base 131, and the other end of the auxiliary swing arm is slidably connected with the frame 110. At one end near the frame 110, the main swing arm 132 and the sub swing arm 133 are connected by a connecting member. In this way, when the user opens and closes the housing 110, the damping force generated by the damping member 134 can be transmitted to the main swing arm 132 via the sub swing arm 133 and the connector, and further transmitted to the housing 110 and the user's hand.

In general, the corresponding rotation axes of the main swing arm 132 and the auxiliary swing arm 133 are parallel but not collinear, the distance between the rotation axis of the main swing arm 132 and the shaft cover 120 is larger, the distance between the rotation axis of the auxiliary swing arm 133 and the shaft cover 120 is smaller, and the frame 110 rotates around the rotation axis of the main swing arm 132 relative to the shaft cover 120. It will be appreciated by those skilled in the art that the rotation axes of the main swing arm 132 and the auxiliary swing arm 133 may be physical rotation axes, respectively, or virtual rotation axes, respectively. When the rotating shaft is a virtual rotating shaft, the rotating shaft is not completely formed by the solid parts of the foldable mobile phone, but is a virtual rotating line formed by the shape constraint and the displacement constraint of different parts in the foldable mobile phone during relative movement.

As shown in fig. 4, in order to avoid a scratch phenomenon between the shaft cover 120 and the frame 110, the foldable mobile phone is generally designed such that a certain clearance gap 200 exists between the shaft cover 120 and the frame 110 at two sides in a folded state, and the theoretical value of the clearance gap 200 is about 0.1mm, and the actual controllable value is generally 0.15mm-2mm. For the sake of being lighter, thinner and more reliable, when the rotating shaft structure 130 is designed, the swing arm base 131 will exceed the outer edge of the shaft cover 120 by 0.05mm to 0.1mm, so that the portion of the swing arm base 131 that exceeds the shaft cover 120 in the folded state is easily seen at the gap 200 between the shaft cover 120 and the frame 110 when the supporting device or the foldable terminal is in the folded state. For convenience of description, a problem in which parts can be seen from the gap 200 between the shaft cover 120 and the frame 110 in the folded state of the supporting device or the foldable terminal will be referred to as a dew-piece problem for short. In addition, due to certain material fluctuation (such as difference in size of the two swing arm bases 131, difference in diameter of the rotating shaft between the two main swing arms 132 and the swing arm bases 131, and the like) existing between the same kind of parts in batch production, the problem of exposed parts still exists when the foldable mobile phone is in a folded state when the gap between the rotating shaft between the main swing arm 132 and the swing arm bases 131 and the frame 110 is controlled to be 200-0.15 mm to 0.2 mm.

In order to improve the above-mentioned problem, this embodiment of the application provides a strutting arrangement and collapsible terminal, this strutting arrangement has set up the shielding piece on the framework, this shielding piece's at least part can be relative the shaft cap motion, in order to dodge the shaft cap in the frame body from folding position to the in-process of expanding the position upset, when the framework is in folding position, at least part and shaft cap butt, with the clearance between shielding frame body and the shaft cap, both can make the frame relative the shaft cap upset not influenced by the shielding piece setting like this, can reduce the spare part between frame body and the shaft cap again to a certain extent and be in the risk that the clearance between frame body and the shaft cap was exposed when the framework was in folding position, make the collapsible terminal that adopts strutting arrangement that this embodiment provided more pleasing to the eye. The foldable terminal includes the supporting device and the flexible display screen, and supports the flexible display screen by the supporting device. The foldable terminal comprises the supporting device, and the gap between the frame body and the shaft cover can be shielded through the shielding piece in the folded state, so that a user cannot see the parts on the frame body and the shaft cover from the gap outside the foldable terminal, and the problem of exposed parts can be solved.

Referring to fig. 5 to 8, the supporting device 100 includes a frame 110, a shaft cover 120, a rotating shaft structure 130, and a shielding member 140. The frame 110 is rotatably connected to the shaft cover 120 through a hinge structure 130, and the frame 110 can be turned between a folded position and an unfolded position relative to the shaft cover 120. As described above, the frame 110 is generally provided with more than two frames, and two adjacent frames 110 are rotatably connected to the same shaft cover 120 through the rotation shaft structure 130. When two adjacent frames 110 are in the unfolded position, the supporting device 100 is in an unfolded state, as shown in fig. 5 to 7; when two adjacent frames 110 are in the folded position, the supporting device 100 is in a folded state, as shown in fig. 8.

The shielding member 140 is disposed on the frame 110, and at least a portion of the shielding member 140 can move relative to the shaft cover 120 to avoid the shaft cover 120 during the overturning of the frame 110 from the folded position to the unfolded position, as shown in fig. 7; when the frame 110 is in the folded position, at least a portion of the shield 140 abuts the shaft cover 120 to shield a gap 200 between the frame 110 and the shaft cover 120, as shown in fig. 8. The avoidance of the shaft cover 120 means that when the frame 110 is turned from the folded position to the unfolded position, the existence of the shielding member 140 does not affect the turning of the frame 110 relative to the shaft cover 120, and at this time, the shielding member 140 may or may not contact the shaft cover 120. It will be appreciated that the existence of the shielding member 140 does not affect the overturning of the frame 110 relative to the shaft cover 120, may have no effect at all, or may have some effect, but can overcome the situation when the palm dials the frame 110, so that the frame 110 can still overturn relative to the shaft cover 120, and no jamming or blocking phenomenon, such as friction contact between the shielding member 140 and the shaft cover 120, but the friction force of the friction contact is far smaller than the thrust exerted by the palm on the frame 110, will not occur.

The gap 200 between the shielding frame 110 and the shaft cover 120 means that the shielding member 140 can cover the communication port between the gap 200 between the shaft cover 120 and the frame 110 and the inner cavity enclosed by the supporting device 100 in the folded state, or insert a certain position in the gap to block the communication between the gap and the inner cavity, so that the user cannot see the parts in the inner cavity enclosed by the supporting device 100 in the folded state through the gap 200 from outside the supporting device 100, and the parts include the parts located on the frame 110 and the parts located on the shaft cover 120.

The shielding member 140 may be arranged in various manners, and may be mounted on the frame 110 in a fixed connection, a detachable connection, a sliding connection, etc., which may be determined according to the structure and function of the shielding member 140. If at least part of the shielding member 140 can extend and retract relative to the shaft cover 120, the shielding member 140 may be an elastic member or a telescopic member with an extending and retracting function, and may be mounted on the frame 110 by a fixed connection manner; if the shielding member 140 is a movable member that can slide at least partially with respect to the shaft cover 120, the driving portion of the movable member may be fixedly mounted on the frame 110, and the movable portion of the movable member may be movably mounted on the frame 110. Of course, other structures may be adopted for the shielding member 140, as long as at least part of the shielding member can move relative to the shaft cover 120, so that the shielding member can avoid the shaft cover 120 during the process of overturning the frame 110 from the folded position to the unfolded position, and at least part of the shielding member 140 abuts against the shaft cover 120 when the frame 110 is in the folded position, so as to shield the gap 200 between the frame 110 and the shaft cover 120.

According to the supporting device 100 provided by the embodiment of the application, the shielding piece 140 is arranged on the frame body 110, at least part of the shielding piece 140 can move relative to the shaft cover 120 so as to avoid the shaft cover 120 in the process of overturning the frame body 110 from the folded position to the unfolded position, and when the frame body 110 is in the folded position, at least part of the shielding piece 140 is abutted against the shaft cover 120 so as to shield the gap 200 between the frame body 110 and the shaft cover 120, so that the overturning of the frame body 110 relative to the shaft cover 120 is not influenced by the arrangement of the shielding piece 140, and the risk that parts between the frame body 110 and the shaft cover 120 are exposed by the gap 200 between the frame body 110 and the shaft cover 120 when the frame body 110 is in the folded position can be reduced to a certain extent, so that the foldable terminal of the supporting device 100 provided by the embodiment of the application is more attractive.

As shown in fig. 7 and 8, in some embodiments, the blinder 140 is an elastic member. The elastic member is fixedly mounted on the frame 110, and at least part of the elastic member is elastically abutted against the shaft cover 120. In this embodiment, the elastic member may be one member or may be an assembly formed by combining a plurality of members, and may be specifically set according to the use requirement.

In general, the width of the gap 200 between the shaft cover 120 and the frame body 110 changes according to the state change between the frame body 110 and the shaft cover 120, and when the frame body 110 is in the folded position, the width of the gap 200 between the frame body 110 and the shaft cover 120 is large, and when the frame body 110 is in the unfolded position, the width of the gap 200 between the frame body 110 and the shaft cover 120 is small. When the solution provided in this embodiment is adopted, since the width of the gap 200 between the frame 110 and the shaft cover 120 is smaller when the frame 110 is in the extended position, the elastic member can be compressed to the first state with smaller volume under the extrusion action of the shaft cover 120, and when the frame 110 is in the folded position, the elastic member will rebound from the first state to the second state due to the enlarged width of the gap 200 between the frame 110 and the shaft cover 120. In the above process, the elastic member may always abut against the shaft cover 120 to cover the gap 200 between the frame 110 and the shaft cover 120, so that the user cannot see the parts located between the frame 110 and the shaft cover 120 and the parts located on the two parts from the gap 200 between the two parts.

It can be understood that the first state and the second state may be the state that the elastic member is compressed, or the first state may be the state that the elastic member is compressed, and the second state may be the state that the elastic member is naturally extended, which may be specifically determined according to the use requirement.

Therefore, when the shielding piece 140 adopts the elastic piece, the gap 200 between the frame body 110 and the shaft cover 120 can be always shielded, and the movement of the shielding piece 140 relative to the shaft cover 120 can be automatically completed by utilizing the extrusion of the shaft cover 120 and the self elastic force, so that other power devices are not needed, the shielding piece 140 has the advantages of simple structure, small occupied space, small influence on the frame body structure and the whole machine, easy engineering realization and effective improvement of the problem of exposed piece. And because the elastic piece has a certain expansion and contraction amount, even if the gap width between the frame body and the shaft cover has bad gap due to material fluctuation, the gap can be well shielded by the elastic piece.

The elastic member may be in various shapes and installation modes according to the use requirement, such as a wedge block, one surface of the elastic member is fixedly connected to the frame 110, and the other surface of the elastic member is in friction contact with the shaft cover 120, or a hollow elastic structure, one end of the elastic member is fixedly connected to the frame 110, and the other end of the elastic member is in friction contact with the shaft cover 120. To make the elastic member smaller, in some embodiments, a first side of the elastic member is fixedly connected to the frame 110, and a second side of the elastic member is bent toward a free end of the frame 110 and is suspended. The first side of the elastic member is a side of the elastic member near the stop surface 111 of the frame 110, and the second side of the elastic member is an opposite side of the first side of the elastic member.

The stop surface 111 of the frame 110 refers to a surface of the frame 110 that contacts the other frame 110 when the two adjacent frames 110 are in the extended position. The free end of the housing 110 refers to the end of the housing 110 remote from the shaft cover 120.

When the frame 110 is in the unfolding position, because the distance between the frame 110 and the shaft cover 120 is smaller, the suspension part of the elastic element is extruded by the shaft cover 120 to bend towards the frame 110, when the frame 110 is overturned from the unfolding position towards the folding position, the distance between the frame 110 and the shaft cover 120 is increased, the suspension part of the elastic element gradually rebounds under the action of self elasticity, and the suspension part of the elastic element is always abutted with the shaft cover 120 in the process, so that the elastic element can always shield the gap 200 between the frame 110 and the shaft cover 120.

The first side fixed connection of elastic component is in framework 110, the second side of elastic component is crooked and unsettled setting towards the free end of framework 110, can make the elastic component adopt the slice structure of volume less, occupy less space between framework 110 and the axle cap 120, simultaneously can make full use of clearance 200 that exists originally between axle cap 120 and framework 110, and can make the area of contact of elastic component and framework 110 less, be difficult for influencing the installation of other structures on the framework 110, and cause adverse effect to the structural stability of framework 110 itself, can also reduction in production cost.

The elastic piece can be an integrally formed sheet body or a combination of a plurality of sheet body structures. In some embodiments, as shown in fig. 9 to 13, the elastic member includes a first elastic portion 141 and a second elastic portion 142. The hardness of the first elastic portion 141 is greater than that of the second elastic portion 142. The plurality of first elastic portions 141 are provided and are provided on the frame 110 at intervals along the longitudinal direction X of the gap 200. The second elastic portion 142 is located between the first elastic portion 141 and the shaft cover 120, and is connected to the first elastic portion 141.

The first elastic portion 141 and the second elastic portion 142 in this embodiment may respectively adopt a sheet-like structure with a smaller volume, may respectively adopt one piece body, or may respectively adopt an assembly formed by combining a plurality of piece bodies. The first elastic portion 141 may be a metal sheet, a plastic sheet, a composite sheet, or the like with a relatively high hardness, and the second elastic portion 142 may be a foam sheet, a rubber sheet, or the like with a relatively low hardness, which may be specifically selected according to the use requirement.

The first elastic portion 141 is mainly used for supporting the second elastic portion 142 and providing elastic force for the second elastic portion 142, so that the second elastic portion is always abutted against the shaft cover 120. The number and size of the first elastic parts 141 may be determined according to the use requirement. If the length of the frame 110 is smaller along the length direction X of the gap 200, the two first elastic portions 141 can stably support the second elastic portion 142 and provide enough elastic force to make the second elastic portion abut against the shaft cover 120, and the two first elastic portions 141 can be provided, and the size of each first elastic portion 141 along the length direction X of the gap 200 is smaller than 1/2 of the length of the gap 200. If the length of the frame 110 is greater along the length direction X of the gap 200, the first elastic portions 141 are provided with two first elastic portions 141 that cannot stably support the second elastic portions 142 and provide a sufficient elastic force, and more first elastic portions 141 are required.

The second elastic portion 142 is mainly used for elastically and frictionally contacting the shaft cover 120 and shielding the gap 200 between the frame 110 and the shaft cover 120. The length of the second elastic portion 142 may be equal to the length of the gap 200 between the frame 110 and the shaft cover 120, or slightly greater than the length of the gap 200, or slightly less than the length of the gap 200, and may be specifically determined according to practical use requirements.

During assembly, the first side of the first elastic portion 141 may be fixedly connected to the frame 110, such that the second side of the first elastic portion 141 is bent toward the free end of the frame 110 and suspended, and then the second elastic portion 142 is mounted on the surface of the first elastic portion 141 facing the shaft cover 120, such that all the first elastic portions 141 are in contact with the second elastic portion 142, and such that the second elastic portion 142 is in elastic contact with the shaft cover 120 after the frame 110 and the shaft cover 120 are assembled together.

It can be understood that the first side of the first elastic portion 141 corresponds to the first side of the elastic member, and is a side close to the stop surface 111 of the frame 110, and the second side of the first elastic portion 141 corresponds to the second side of the elastic member, and is a side opposite to the first side.

In this embodiment, the first elastic portion 141 has a hardness greater than that of the second elastic portion 142, but a size smaller than that of the second elastic portion 142, so that the first elastic portion 141 is disposed close to the frame 110, and can occupy a smaller installation space on the surface of the frame 110, and simultaneously can stably support the second elastic portion 142, and the second elastic portion 142 with a smaller hardness contacts the shaft cover 120, so that the risk of abrasion occurring during contact between the two portions can be reduced, and multiple purposes are achieved.

In some embodiments, as shown in fig. 11, the second elastic portion 142 includes a support 1421 and an elastic sheet 1422. The supporting member 1421 is disposed on a surface of the first elastic portion 141 facing the shaft cover, and is connected to all the first elastic portions 141, and the elastic sheet 1422 is disposed on a surface of the supporting member 1421 facing the shaft cover.

In this embodiment, the supporting member 1421 may be a single member or an assembly formed by combining a plurality of members, and may be specifically determined according to the use requirement. The supporting member 1421 may be a metal member, a plastic member, or the like having a relatively high hardness, and the supporting member 1421 may have a certain elasticity or may not have elasticity, so long as the supporting of the elastic sheet 1422 is achieved. The elastic sheet 1422 may be made of foam, composite material, or the like with high elasticity and light weight.

By adopting the scheme provided by the embodiment, the second elastic part 142 can have certain supporting strength and flatness, so that different areas of the second elastic part 142 can be in close contact with the axle cover, the required number of the first elastic parts 141 is smaller, and meanwhile, the part (namely the elastic sheet 1422) of the second elastic part 142, which is in contact with the axle cover, can be made of a material with larger elasticity and lighter weight, so that the risk of abrasion of the axle cover when the second elastic part 142 is in frictional contact with the axle cover can be reduced to a certain extent.

In an alternative embodiment, the first elastic portion is a spring, the supporting member is a long strip steel sheet, and the elastic sheet is long strip black foam. When the frame is prepared, the accommodating groove is formed near the stop surface of the frame body, the first elastic parts are welded at a plurality of positions in the accommodating groove, the supporting pieces are welded on the first elastic parts, and then the elastic pieces are adhered and covered on the supporting pieces. When the supporting device is in a flattened state, the whole elastic piece is extruded into the accommodating groove by the shaft cover, and when the supporting device is in a folded state, the first elastic part is reset due to the increase of the gap between the shaft cover and the frame body, the elastic piece (namely black foam) occupies the gap space and shields the shaft area part, so that the problem of exposed piece of the shaft area part in the folded state is solved.

In any of the above embodiments, the elastic member may be directly mounted on the surface of the frame 110, or some mounting structures may be added to the frame 110, and then the elastic member is mounted on the frame 110. Since the elastic member generally has a certain volume for realizing a certain function, and the volume is generally larger than the volume of the space corresponding to the gap 200 between the frame 110 and the shaft cover 120, in order to enable the installation of the elastic member to adapt to the width of the gap 200 between the existing frame 110 and the shaft cover 120, in some embodiments, as shown in fig. 7 and 8, a receiving groove 112 is formed on a surface of the frame 110 opposite to the shaft cover 120, and the receiving groove 112 is used for receiving the elastic member. The accommodating groove 112 in this embodiment may be configured to accommodate the entire elastic member as needed, or may be configured to accommodate a part of the elastic member, and may be specifically determined according to the use requirement. The accommodating groove 112 can make the gap 200 between the frame 110 and the shaft cover 120 not to be increased due to the addition of the elastic member, so that the whole structure of the supporting device 100 is compact.

The receiving groove 112 may be a single groove body or a combination groove of a plurality of groove bodies. As shown in fig. 14, in some embodiments, the receiving groove 112 includes a first groove body 1121 and a second groove body 1122. The first groove 1121 is configured to receive the second elastic portion. The second groove 1122 is formed at the bottom of the first groove 1121 and communicates with the first groove 1121. The second groove 1122 is used to accommodate the first elastic part. Thus, the first slot 1121 may be sized to fit the second spring portion, and the second slot 1122 may be sized to fit the first spring portion. The second groove 1122 is located at a position corresponding to a larger depth of the accommodating groove 112, and other areas of the first groove 1121 are corresponding to smaller depths of the accommodating groove 112. In this way, compared with the structure that the different areas of the accommodating groove 112 have the same depth, the accommodating groove 112 occupies smaller space, that is, less material on the frame 110 needs to be removed when the accommodating groove 112 is processed, so that the adverse effect on the stability of the frame 110 is smaller.

When the shielding member 140 is an elastic member, the gap 200 between the frame 110 and the shaft cover 120 may be shielded, but the elastic member may always be in frictional contact with the shaft cover 120, and the shaft cover 120 may be inevitably worn or the elastic member may be worn. To ameliorate this problem, as shown in fig. 15, 16 and 17, in other embodiments, the blinder 140 includes a slider 146 and a drive assembly 147. The slider 146 is slidably provided in the housing 110 and is movable between a first position where it is retracted from the shaft cover 120 and a second position where it abuts against the shaft cover 120. The driving assembly 147 is disposed on the frame 110, and is used for driving the sliding member 146 to move relative to the frame 110.

The sliding member 146 in this embodiment is generally equal to the gap between the frame 110 and the shaft cover 120, and may be slightly shorter or longer than the gap between the frame 110 and the shaft cover 120, so long as the sliding member 146 is moved to the second position and the components on the frame 110 and the shaft cover 120 cannot be seen from outside.

The drive assembly 147 may be a drive assembly without an independent power source or may be a drive assembly with an independent power source. The driving assembly without an independent power source may be directly connected or indirectly contacted with the auxiliary swing arm 133, so as to drive the sliding piece 146 to move relative to the shaft cover 120 when the auxiliary swing arm 133 moves relative to the shaft cover 120, so as to adjust the position of the sliding piece. The drive assembly with independent power source may be selected to suit the size of the support apparatus 100 and the needs of the application. If the supporting device is large, a driving assembly with a micro motor, a micro cylinder and the like can be adopted.

The shielding piece 140 provided by the embodiment has a simple structure, is convenient to operate, and can reduce the friction between the shielding piece 140 and the shaft cover 120 to a certain extent compared with the shielding piece 140 by adopting an elastic piece, so that the risk of abrasion of the shaft cover 120 in the long-term use process is reduced.

Because of the small size of some collapsible terminals, it is not desirable to select a drive assembly having an independent power source. If the foldable terminal is a foldable mobile phone, the supporting device is smaller in thickness, and a driving assembly with an independent power source is not easy to select. For these foldable terminals, the drive assembly described above is more suitable for use with drive assemblies having no independent power source. As mentioned above, the pivot structure generally includes a swing arm base, a main swing arm, an auxiliary swing arm, and the like, where the auxiliary swing arm is rotatably connected with the shaft cover and slidably connected with the frame body. When the frame and the shaft cover are turned relatively, the end, which is contacted with the frame, of the auxiliary swing arm can slide relatively with the frame, and in some embodiments, the driving assembly utilizes the phenomenon. As shown in fig. 15, 16 and 17, the driving unit 147 includes a protrusion 1471 protruding on the auxiliary swing arm 133, and the protrusion 1471 can abut against the sliding member 146 and push the sliding member 146 to move from the first position to the second position during the process of turning the frame 110 from the extended position to the folded position.

The protrusion 1471 may be integrally formed with the sub-arm 133, or may be attached to the sub-arm 133 by plugging, welding, or adhesive bonding. The protrusion 1471 may be a bump, a semi-circular protrusion, or other structure, so long as the protrusion 1471 is capable of abutting at least a portion of the slider 146 to push the slider 146 from the first position to the second position during the overturning of the frame 110 from the unfolded position to the folded position.

It can be appreciated that the protrusion 1471 can abut against at least a portion of the sliding member 146 to push the sliding member 146 to move from the first position to the second position during the process of turning the frame 110 from the unfolded position to the folded position, and the protrusion 1471 may abut against the sliding member 146 when the frame 110 is in the unfolded position, and push the sliding member 146 to the second position when the frame 110 is turned to the folded position; the protrusion 1471 may not contact the slider 146 when the housing 110 is in the extended position, and may start to contact the slider 146 at a certain position during the process of turning from the extended position to the folded position, and may push the slider 146 to the second position when the housing 110 is turned to the folded position.

When in use, as the rotation radius of the auxiliary swing arm 133 is smaller than that of the frame 110, the distance between the frame 110 and the shaft cover 120 is gradually increased in the process of overturning the frame 110 from the unfolded position to the folded position relative to the shaft cover 120, and the distance between the auxiliary swing arm 133 and the shaft cover 120 is unchanged, so that one end of the auxiliary swing arm 133 away from the shaft cover 120 gradually slides relative to the frame 110 towards the stop surface 111 of the frame 110, and the sliding piece 146 is positioned close to the stop surface 111 of the frame 110. In the above-described turning process of the frame 110, there is a point where the protrusion 1471 on the sub-swing arm 133 abuts against the slider 146, and then, if the frame 110 is still rotated in the original direction, the sub-swing arm 133 and the protrusion 1471 continue to slide relative to the frame 110 toward the stop surface 111 of the frame 110, so that the slider 146 is pushed to move out of the frame 110 until the frame 110 rotates in place, and the sub-swing arm 133 stops the relative sliding with the frame 110 and the slider 146 abuts against the shaft cover 120.

When the frame 110 is turned over from the folded position to the unfolded position relative to the shaft cover 120 along the opposite direction, the end of the auxiliary swing arm 133 away from the shaft cover 120 slides relative to the frame 110 towards the direction away from the stop surface 111 of the frame 110, and the distance between the auxiliary swing arm 133 and the sliding member 146 is gradually increased, at this time, the sliding member 146 can be still and motionless under the friction force of the shaft cover 120 and the pushing action of the sliding member 146 on the adjacent frame 110, and after the frame 110 is turned over to the unfolded position, the auxiliary swing arm is completely contracted on the frame 110.

By adopting the scheme provided by the embodiment, through adding the convex part 1471 on the auxiliary swing arm 133 and through the mode of the convex part 1471 and the sliding part 146, the sliding part 146 can be pushed to move relative to the shaft cover 120 by means of the characteristic that the auxiliary swing arm 133 can slide relative to the frame body 110 in the overturning process, and a power source is not required to be additionally arranged, so that the supporting device 100 is simple in structure, occupies small space, has small influence on the frame body structure and the whole machine, is easy to realize engineering, and can effectively improve the problem of exposed parts.

To further enhance the intelligence of the drive assembly, in some embodiments, as shown in FIG. 15, the drive assembly 147 further includes a magnetic attraction piece 1472 disposed on the housing 110. The magnetic attraction piece 1472 can attract the slider 146 to the first position by magnetic force during the overturning of the frame 110 from the folded position to the unfolded position. The magnetic attraction piece 1472 can be a permanent magnet or an electromagnet, and can be specifically selected according to the use requirement.

The above-mentioned magnetic attraction piece 1472 can adsorb the sliding piece 146 from the second position to the first position by magnetic force during the process of turning the frame 110 from the folded position to the unfolded position, which means that the distance between the sliding piece 146 and the magnetic attraction piece 1472 can reach the magnetic attraction range of the magnetic attraction piece 1472 during the process of turning the frame 110 from the folded position to the unfolded position, so that the magnetic attraction piece 1472 can adsorb the sliding piece 146 from the second position to the first position by magnetic force, or adsorb the sliding piece 146 from any position between the second position and the first position to the first position.

It can be appreciated that when the driving assembly 147 includes both the protrusion 1471 and the magnetic attraction piece 1472, during the sliding process of the auxiliary swing arm 133 relative to the frame 110, the protrusion 1471 abuts against the sliding piece 146 and pushes the sliding piece 146 to move relative to the frame 110, so as to overcome the attraction force of the magnetic attraction piece 1472 to the sliding piece 146.

By adopting the scheme provided by the embodiment, when the frame 110 is turned over relative to the shaft cover 120, the sliding piece 146 can automatically move from the first position to the second position, and also can automatically move from the second position to the first position, and parts of the driving assembly 147 are fewer, so that the assembly and the processing are convenient.

In some embodiments, as shown in fig. 18, the magnetic attraction pieces 1472 are provided with two groups and are respectively arranged at two sides of the protruding part. One or more magnetic pieces 1472 can be arranged on each group of magnetic pieces 1472, and the structures and the numbers of the magnetic pieces 1472 in each group of magnetic pieces 1472 can be the same or different, and can be specifically determined according to the use requirement. The two groups of magnetic attraction pieces 1472 can make the stress of the sliding piece 146 relatively balanced, and can realize stable movement.

As shown in fig. 19, in some embodiments, the frame 110 is further provided with a mounting groove 115, and the magnetic attraction member is mounted in the mounting groove 115. The size of the mounting groove 115 may be larger than or smaller than the size of the magnetic attraction member, or may be equal to the size of the magnetic attraction member, and may be specifically determined according to the use requirement. The volume of the mounting groove 115 should be greater than or equal to the volume of the magnetic attraction member if the magnetic attraction member cannot protrude from the surface of the frame 110, and the volume of the mounting groove 115 may be set smaller than the volume of the magnetic attraction member if the magnetic attraction member may have a portion protruding from the surface of the frame 110. The installation groove 115 not only limits the installation position of the magnetic attraction piece, and is convenient for standardized production, but also ensures that the magnetic attraction piece does not protrude out of the surface of the frame 110 or protrudes out of the surface of the frame 110 as little as possible, thereby reducing the adverse effect of the installation of the magnetic attraction piece on other original structures on the frame 110. At the same time, the installation of the mounting groove 115 is convenient for the installation and replacement of the magnetic attraction piece.

As shown in fig. 20 and 21, in some embodiments, the slider 146 includes a sheet 1461 and a slider 1462. The sheet 1461 is located between the housing 110 and the shaft cover 120, and the slider 1462 is provided so as to protrude from a surface of the sheet 1461 facing the housing 110, and the slider 1462 is in sliding contact with the housing 110.

The sheet 1461 and the slider 1462 may be made of the same material or may be made of different materials, and may be specifically determined according to the use requirement.

Along the length direction X of the gap 200, the length of the slider 1462 is smaller than the length of the sheet 1461, so that the sheet 1461 is in sliding contact with the frame 110 through the slider 1462, so that the contact area between the slider 146 and the frame 110 is smaller, and adverse effects of the arrangement of the slider 146 on the original structure on the frame 110 are reduced.

In addition, the thickness of the sliding movement along the thickness direction Y of the housing 110 may be greater than the thickness of the sheet 1461. The protrusion 1471 and the magnetic attraction piece 1472 in the driving assembly 147 can be in contact with the sliding piece 146 through contact with the sliding block 1462, so that the contact area between the corresponding part in the driving assembly 147 and the sliding piece 146 is larger, and the sliding piece 146 can stably move relative to the frame 110 under the action of the driving assembly 147.

The sliding member 146 adopts the structure provided in this embodiment, which is convenient for the sliding member 146 to extend out of the frame 110 through the narrow space between the shaft cover 120 and the frame 110, and can make the sliding member 146 stably contact with the frame 110 and the driving assembly 147, so that the sliding member 146 can stably move relative to the frame 110 and the shaft cover 120, and multiple purposes are achieved.

To further reduce the risk of hard collisions between the slider 146 and the shaft cover 120 when the slider 146 abuts against the shaft cover 120, the slider 146 may further include an elastomer 1463 in some embodiments, as shown in fig. 20 and 21. The elastic body 1463 is provided on the sheet 1461. The sheet 1461 is in contact with the shaft cover 120 via an elastic body 1463. The elastic body 1463 may be made of foam, sponge, elastic composite material, or the like, and may be attached to the side of the sheet body 1461 near the shaft cover 120 by means of bonding, plugging, or the like, so that when the slider 146 contacts the shaft cover 120, the sheet body 1461 is not in direct contact with the shaft cover 120, but in contact with the shaft cover 120 through the elastic body 1463. This achieves elastic contact of the slider 146 with the shaft cover 120, reducing the risk of hard collisions when the two abut each other. Meanwhile, since the elastic body 1463 has a certain elasticity, when the gap 200 between the frame 110 and the shaft cover 120 has poor spacing due to material fluctuation, the sliding piece 146 can still be abutted against the shaft cover 120, so as to realize shielding of the gap 200 between the frame 110 and the shaft cover 120.

The sheet 1461 may be a flat plate, a sheet having a certain degree of curvature, or other sheet structures. Since the surface of the shaft cover 120 opposite to the frame body 110 is generally curved, the surface of the frame body 110 opposite to the shaft cover 120 is also curved, which results in a shape of the gap 200 between the frame body 110 and the shaft cover 120 having a certain curvature, so that the sheet 1461 better adapts to the shape of the space between the frame body 110 and the shaft cover 120, and thus the volume of the sheet 1461 is smaller. In some embodiments, the sheet 1461 is a curved member having a curved surface facing the shaft cover 120. The curved surface of the curved surface member may be a standard curved surface or an irregular curved surface, and may be installed in the gap 200 between the frame 110 and the shaft cover 120, and may be moved in the gap 200 relative to the frame 110 and the shaft cover 120, so as to meet the use requirement. In this embodiment, the curved member may be a member having both curved surfaces, or may be a member having only one surface facing the shaft cover 120, and may be determined according to the shape of the surface of the frame body that is to be in contact with the curved member. If the shape of one surface of the frame body, which is contacted with the curved surface piece, is a curved surface, then the surface of the curved surface piece, which faces the frame body, can also be a curved surface, so that the two surfaces of the curved surface piece are respectively matched with the corresponding surfaces of the shaft cover and the frame body, and the volume of the curved surface piece is smaller. If the shape of the surface of the frame body, which is contacted with the curved surface piece, is a plane, the surface of the curved surface piece, which faces the frame body, can be a plane, so that the two surfaces of the curved surface piece are respectively matched with the corresponding surfaces of the shaft cover and the frame body, and the volume of the curved surface piece is smaller.

As shown in fig. 19, in some embodiments, a first sliding groove 113 is formed on the frame 110, and the slider is slidably disposed in the first sliding groove 113. The size of the first sliding groove 113 may be slightly larger than the size of the sliding block, and may be equal to the size of the sliding block, as long as the sliding block can be inserted into the first sliding groove 113 and can move in the first sliding groove 113.

The first sliding groove 113 not only enables the sliding piece to move in the preset track, but also enables the width of the gap between the frame 110 and the shaft cover not to be increased due to the addition of the sliding piece, so that the supporting device is compact in structure.

As shown in fig. 19, in addition to the first sliding groove 113, in some embodiments, a second sliding groove 114 is formed on the frame 110. The second sliding groove 114 is located at one side of the first sliding groove 113 away from the stop surface of the frame 110, and is in communication with the first sliding groove 113. The second chute 114 is for receiving the boss and for movement of the boss. The size of the second chute 114 may be slightly larger than the size of the protruding portion, or may be comparable to the size of the protruding portion, as long as the protruding portion can be inserted into the second chute 114 and can move within the second chute 114.

The second chute 114 is provided to enable the protrusion to move in a preset track, and the width of the gap between the frame 110 and the shaft cover is not required to be increased due to the addition of the protrusion, so that the supporting device is compact in structure. Meanwhile, the connection structure between the frame 110 and the auxiliary swing arm does not need to be changed, so that the design and the processing are convenient.

In some embodiments, at least a portion of the shield abuts the shaft cover to shield the first port of the gap when the frame is in the folded position. The first port is an opening at one end of the gap away from the stop surface of the frame. In this way, the shielding piece is positioned at the inner end of the gap between the frame body and the shaft cover and is not easy to be seen by a user from the outside of the supporting device, so that the supporting device and the foldable terminal are attractive in appearance.

In some embodiments, the color of the side of the portion of the shield projecting out of the gap when the frame is in the folded position matches the color of the environment within the gap. The ambient color refers to the color that can be seen from the outside of the support device into the gap when the support device is in the folded state, and also refers to the color of the space in the gap. In general, the color of the environment in the gap is black, so that the color of the side of the portion of the shield protruding out of the frame facing the gap may be black or other colors which are not easily found in black. If the environmental color in the gap is other colors, the color of the side of the part of the shielding piece protruding out of the frame body facing the gap can be the corresponding color or other colors which are not easy to be found in the environmental color in the gap. Therefore, when the supporting device is in a folded state, a user cannot find the existence of the shielding piece from the gap, and the attractive degree of the product can be further improved.

In an alternative embodiment, the sheet body in the sliding piece is an irregular arc steel sheet, the elastic body in the sliding piece is black soft rubber adhered to one side wall of the irregular arc steel sheet, and the sliding block is positioned on the other side of the irregular arc steel sheet and connected with the bottom surface of the irregular arc steel sheet. The magnetic attraction piece is a magnet, and the sliding block is a metal piece and can be attracted by the magnetic attraction piece. During preparation, a first chute and a second chute can be formed at the positions of the frame body and the auxiliary swing arm, then a sliding block in the sliding piece is placed in the first chute, then the sheet body is placed on the surface of the frame body, the bottom surface of one side of the sheet body is contacted with the sliding block, and then the two are welded. The steel sheet sliding block structure with the soft rubber is driven by the auxiliary swing arm in the opening and closing process, and can change the extending state of the steel sheet sliding block structure relative to the joint surface of the frame body and the shaft cover when the steel sheet sliding block structure is unfolded to a folding state. When the supporting device is in a flattened state, the sliding piece is positioned on the frame body, the shaft cover is kept away, and when the supporting device is in a folded state, the auxiliary swing arm pushes the sliding piece to move 0.2-0.4 mm along with the sheet body to slide out of the surface of the frame body, so that a gap between the shaft cover and the frame body is filled, shaft area parts are shielded, and the problem of shaft area part exposure is solved. When the sliding block is opened again, the sliding block moves along with the auxiliary swing arm to be attached to the magnet again under the action of the magnetic force of the magnet, the sliding piece is located on the frame body again, and the shaft cover is kept away.

In another embodiment of the present application, a foldable terminal is also provided. The foldable terminal comprises a flexible display screen and the supporting device provided by any of the embodiments. The flexible display screen is mounted on the support device.

As mentioned above, the foldable terminal in this embodiment may be a foldable mobile phone, or may be other folding screen devices.

The foldable terminal comprises the supporting device provided by any one of the embodiments, and the gap between the frame body and the shaft cover can be shielded through the shielding piece in a folded state, so that a user cannot see the parts on the frame body and the shaft cover from the gap outside the foldable terminal, and the problem of exposed parts can be improved.

Finally, it should be noted that: the foregoing is merely a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
