[0002] With the development of technology, the appearance (ID) form of electronic devices (such as mobile phones, tablet computers, etc.) has a tendency to develop from straight-bar machines to foldable machines. The foldable terminal has a large-area screen in the open state, fully meeting the visual experience of consumers, and is small in volume and easy to carry in the closed state. The rotating shaft is a core component of the foldable terminal. During the assembly and use of the foldable terminal, the shaft cover of the rotating shaft is prone to problems such as scratching and damage. However, in the prior art, the shaft cover of the rotating shaft is difficult to disassemble, and the maintenance or replacement cost is relatively high. Summary of the Utility Model

[0003] This application provides a shaft cover assembly, a rotating shaft, and a foldable terminal, which can solve the technical problem that the shaft cover of the rotating shaft in the prior art is difficult to disassemble, and the maintenance or replacement cost is relatively high.

[0004] To solve the above problems, in a first aspect, this application provides a shaft cover assembly. The shaft cover assembly is applied to a rotating shaft. The rotating shaft is used for a foldable terminal and is used to realize the unfolding and folding of the foldable terminal.

[0005] The shaft cover assembly includes a shaft cover and a base. The shaft cover includes a cover body, a first clamping body, and a second clamping body. The cover body is provided with an installation groove. The first clamping body and the second clamping body are respectively connected to opposite sides in the width direction of the cover body and face the installation groove. The base includes a first outer side and a second outer side, and the first outer side and the second outer side are arranged opposite to each other along the width direction of the base. The first outer side is provided with a first clamping groove, and the second outer side is provided with a second clamping groove. The base is installed in the installation groove, the first clamping body is engaged with the first clamping groove, and the second clamping body is engaged with the second clamping groove.

[0006] In this embodiment, by providing a first clamping body and a second clamping body on the shaft cover, correspondingly providing a first clamping groove and a second clamping groove on the base, and clamping the first clamping body in the first clamping groove and the second clamping body in the second clamping groove, the clamping connection between the shaft cover and the base can be realized, so that the shaft cover is detachable relative to the base. During the use of the foldable terminal, if the shaft cover needs to be replaced, only the shaft cover needs to be disassembled from the base, which is convenient for repairing or replacing the shaft cover without disassembling the entire rotating shaft, thereby improving the maintenance efficiency and reducing the maintenance cost.

[0007] When the shaft cover is a detachable structure, the shaft cover can be used as a separate decorative part for customized design, so as to meet the needs of different users and improve the user experience. Exemplarily, the shaft cover can be set in different colors, or there are customized patterns on the outer surface of the shaft cover. Herein, the "outer surface" of the shaft cover refers to the surface of the shaft cover located outside the receiving groove.

[0008] In this embodiment, by arranging the first clamping body and the second clamping body on opposite sides in the width direction of the shaft cover, the shaft cover and the base are clamped on both opposite sides in the width direction of the shaft cover assembly, so as to improve the connection stability between the shaft cover and the base, and further improve the structural stability of the shaft cover assembly.

[0009] In a possible implementation manner, the first clamping groove includes a first sub-groove and a second sub-groove. The first sub-groove and the second sub-groove are arranged along the thickness direction of the base and communicate with each other. The depth of the second sub-groove is greater than the depth of the first sub-groove. The first clamping body includes a first connecting portion and a first clamping portion. The first connecting portion is connected to the cover body, the first clamping portion is connected to one end of the first connecting portion facing away from the cover body, and the first clamping portion extends into the installation groove. The first connecting portion is installed in the first sub-groove, and the first clamping portion is installed in the second sub-groove.

[0010] In this embodiment, by setting the depth of the second sub-groove to be greater than the depth of the first sub-groove and clamping the first clamping portion in the second sub-groove, it can be avoided that the first clamping portion disengages from the second sub-groove, so as to improve the clamping stability between the first clamping body and the first clamping groove, and further improve the connection stability between the shaft cover and the base.

[0011] In a possible implementation manner, the first clamping groove includes a first guiding arc surface. The first guiding arc surface is arc-shaped and is connected between the bottom wall of the first sub-groove and the side wall of the second sub-groove.

[0012] In this embodiment, by connecting the bottom wall of the first sub-groove and the inner wall of the second sub-groove through the first guiding arc surface, when the shaft cover is installed on the base, the first clamping portion can slide along the first guiding arc surface in an arc shape into the second sub-groove, so as to improve the smoothness of the installation process of the shaft cover assembly and reduce the difficulty of installing the shaft cover on the base. At the same time, during the disassembly process of the shaft cover, the first clamping portion can slide out of the second sub-groove along the first guiding arc surface, so as to improve the smoothness of the disassembly process of the shaft cover assembly, reduce the disassembly difficulty of the shaft cover, and improve the maintenance efficiency of the shaft cover assembly.

[0013] In a possible implementation manner, the second card slot includes a third sub-slot and a fourth sub-slot. The third sub-slot and the fourth sub-slot are arranged along the thickness direction of the base and communicate with each other. The depth of the fourth sub-slot is greater than that of the third sub-slot. The second clamping body includes a second connecting portion and a second clamping portion. The second connecting portion is connected to the cover body, and the second clamping portion is connected to one end of the second connecting portion facing away from the cover body, and the second clamping portion extends towards the inside of the installation slot. The second connecting portion is installed in the third sub-slot, and the second clamping portion is installed in the fourth sub-slot.

[0014] In this embodiment, by setting the depth of the fourth sub-slot to be greater than that of the third sub-slot and clamping the second clamping portion in the fourth sub-slot, it is possible to prevent the second clamping portion from disengaging from the fourth sub-slot, thereby improving the clamping stability between the second clamping body and the second card slot, and further improving the connection stability between the shaft cover and the base.

[0015] In a possible implementation manner, the second card slot includes a second guiding arc surface. The second guiding arc surface is arc-shaped and is connected between the bottom wall of the third sub-slot and the side wall of the fourth sub-slot.

[0016] In this embodiment, by connecting the bottom wall of the third sub-slot and the inner wall of the fourth sub-slot through the second guiding arc surface, when the shaft cover is installed on the base, the second clamping portion can slide along the second guiding arc surface in an arc shape into the fourth sub-slot, thereby improving the smoothness of the installation process of the shaft cover assembly and reducing the difficulty of installing the shaft cover on the base. At the same time, during the disassembly process of the shaft cover, the second clamping portion can slide out of the fourth sub-slot along the second guiding arc surface, thereby further improving the smoothness of the disassembly process of the shaft cover assembly, reducing the disassembly difficulty of the shaft cover, and improving the maintenance efficiency of the shaft cover assembly.

[0017] In a possible implementation manner, the first connecting portion is provided with a first notch. The opening of the first notch is located on the surface of the first connecting portion facing the installation slot. The first notch is spaced from the first clamping portion, and the first notch is located on one side of the first clamping portion close to the bottom wall of the installation slot.

[0018] It can be understood that the first notch divides the first clamping body into a first part and a second part, and the first part and the second part are connected along the height direction of the first clamping body. During the disassembly and installation processes of the shaft cover assembly, the base abuts against the first clamping portion, causing the first clamping body to deform in a direction away from the base. In this embodiment, by providing the first notch on the first clamping body, the abutting force received by the first clamping body is concentrated at the first notch, so that the deformation amount of the second part is smaller than that of the first part, that is, the deformation of the second part can be reduced, thereby the deformation amount of the bottom plate can be reduced, and further the convex printing or dent on the appearance surface of the shaft cover can be reduced or even avoided, and further the consistency of the appearance of the shaft cover can be improved, enhancing the user experience.

[0019] In a possible implementation manner, the second connecting portion is provided with a second notch, the opening of the second notch is located on the surface of the second connecting portion facing the installation groove, the second notch is spaced from the second clamping portion, and the second notch is located on one side of the second clamping portion close to the bottom wall of the installation groove.

[0020] It can be understood that the second notch divides the second clamping body into a third part and a fourth part, and the third part and the fourth part are connected along the height direction of the second clamping body. During the disassembly and installation processes of the shaft cover assembly, the base abuts against the second clamping portion, causing the second clamping body to deform in a direction away from the base. In this embodiment, by providing the second notch on the second clamping body, the abutting force received by the second clamping body is concentrated at the second notch, so that the deformation amount of the fourth part is smaller than that of the third part, that is, the deformation of the fourth part can be reduced, thereby the deformation amount of the bottom plate can be reduced, and further the convex printing or dent on the appearance surface of the shaft cover can be reduced or even avoided, and further the consistency of the appearance of the shaft cover can be improved, enhancing the user experience.

[0021] In a possible implementation manner, the shaft cover further includes a first positioning block and a second positioning block. The first positioning block and the second positioning block are respectively connected to opposite sides in the width direction of the cover body. The first positioning block is spaced from the first clamping body and is disposed opposite to the first outer side surface. The second positioning block is spaced from the second clamping body and is disposed opposite to the second outer side surface.

[0022] In this embodiment, by providing the first positioning block and the second positioning block on the shaft cover, the matching area between the shaft cover and the base can be increased, thereby improving the connection stability between the shaft cover and the base. Moreover, in this embodiment, by respectively arranging the first positioning block and the second positioning block on opposite sides in the width direction of the shaft cover, the shaft cover can be limited in the width direction of the shaft cover assembly, so that the shaft cover can be reduced or even avoided from shaking in the width direction, and further the connection stability between the shaft cover and the base can be improved.

[0023] In a possible implementation, the cover body includes a bottom plate and a first end plate, and the first end plate is connected to one side of the bottom plate in the length direction. A disassembly opening is provided on the first end plate, and one end of the disassembly opening penetrates the outer surface of the first end plate.

[0024] When it is necessary to disassemble the shaft cover from the base, by placing the disassembly tool in the disassembly opening and applying a force to the shaft cover away from the base, the first clamping body can be unlocked from the first clamping groove, and the second clamping body can be unlocked from the second clamping groove, so that the shaft cover is separated from the base, and the disassembly of the shaft cover is realized, thereby improving the disassembly efficiency and the maintenance efficiency.

[0025] In a possible implementation, the base includes a first end face, and the first end face is located on one side of the base in the length direction. The shaft cover assembly further includes a limiting member, and the limiting member is arranged in the installation groove and located between the first end plate and the first end face.

[0026] In this embodiment, by arranging a limiting member between the first end plate and the first end face, the shaft cover can be limited in the length direction of the shaft cover assembly, so that the shaft cover can be prevented from shaking in the length direction of the shaft cover assembly, and further the connection stability between the shaft cover and the base can be improved.

[0027] In a possible implementation, the base further includes a second end face. The second end face is arranged opposite to the first end face along the length direction of the base. The shaft cover further includes a second end plate. The second end plate is connected to the bottom plate and is arranged opposite to the first end plate along the length direction of the shaft cover. There are two limiting members. One limiting member is arranged between the first end plate and the first end face, and the other limiting member is arranged between the second end plate and the second end face.

[0028] In this embodiment, by arranging limiting members between the first end plate and the first end face and between the second end plate and the second end face, the shaft cover can be limited at both opposite ends in the length direction of the shaft cover assembly, so that the connection stability between the shaft cover and the base can be further improved.

[0029] In a possible implementation, the limiting member is a rubber pad, or a foam, or an adhesive, or glue.

[0030] When the limiting member is a rubber pad or a foam, the limiting member abuts against the surface of the first end plate facing the base and the first end face. When the limiting member is glue or an adhesive, the limiting member is bonded between the surface of the first end plate facing the base and the first end face, which can further improve the stability between the shaft cover and the base.

[0031] In a possible implementation manner, there are a plurality of the first card slots, and the plurality of the first card slots are arranged at intervals along the length direction of the first outer side surface. There are a plurality of the first clamping bodies, and the plurality of the first clamping bodies are arranged at intervals along the length direction of the cover body and correspond to the first card slots one by one. Each of the first clamping bodies is engaged with the corresponding first card slot.

[0032] In this embodiment, by arranging a plurality of the first clamping bodies along the length direction of the cover body and correspondingly arranging a plurality of the first card slots on the base, the base and the shaft cover can be clamped at a plurality of positions in the length direction of the shaft cover assembly, thereby improving the connection stability between the shaft cover and the base.

[0033] In a possible implementation manner, there are a plurality of the second card slots, and the plurality of the second card slots are arranged at intervals along the length direction of the second outer side surface. There are a plurality of the second clamping bodies, and the plurality of the second clamping bodies are arranged at intervals along the length direction of the cover body and correspond to the second card slots one by one. Each of the second clamping bodies is engaged with the corresponding second card slot.

[0034] In this embodiment, by arranging a plurality of the second clamping bodies along the length direction of the cover body and correspondingly arranging a plurality of the second card slots on the base, the base and the shaft cover can be clamped at a plurality of positions in the length direction of the shaft cover assembly, thereby improving the connection stability between the shaft cover and the base.

[0035] In a second aspect, the present application provides a rotating shaft. The rotating shaft includes a first rotating assembly, a second rotating assembly, and the above shaft cover assembly. The first rotating assembly and the second rotating assembly are both installed on the base and are respectively located on opposite sides in the width direction of the base, and both the first rotating assembly and the second rotating assembly are rotatably connected to the base.

[0036] Among them, the first rotating assembly may include a swing arm, a wedge block, a door panel, etc. The second rotating assembly may include a swing arm, a wedge block, a door panel, etc. Among them, the swing arm may be any one or more of a main swing arm, a sub-swing arm, a synchronous swing arm, and a damping swing arm.

[0037] In a third aspect, the present application provides a foldable terminal. The foldable terminal includes a first housing, a second housing, and the above rotating shaft. The rotating shaft is connected between the first housing and the second housing, the first rotating assembly is connected to the first housing, and the second rotating assembly is connected to the second housing.

[0038] When the first housing rotates, it drives the first rotating component to rotate relative to the base. When the second housing rotates, it drives the second rotating component to rotate relative to the base, so that the foldable terminal can be switched between the folded state and the unfolded state. When the first housing and the second housing rotate towards each other through the rotating shaft, the foldable terminal is in the folded state. When the first housing and the second housing rotate away from each other through the rotating shaft, it drives the first housing and the second housing to rotate away from each other, so that the foldable terminal is in the unfolded state.

[0039] During the use of the foldable terminal provided in this application, if the shaft cover needs to be repaired or replaced, only the shaft cover needs to be disassembled from the base, which is convenient for repairing or replacing the shaft cover without disassembling the entire rotating shaft, thereby reducing the maintenance cost.

[0040] In a possible implementation manner, the disassembly opening of the shaft cover assembly exposes the outside of the foldable terminal.

[0041] In this embodiment, by exposing the disassembly opening to the outside of the foldable terminal, when disassembling the shaft cover, the disassembly tool can directly extend into the disassembly opening without disassembling other components of the foldable terminal, thereby further facilitating the disassembly of the shaft cover and further reducing the maintenance cost.

[0042] In summary, for the shaft cover assembly provided in this application, by providing a first clamping body and a second clamping body on the shaft cover, and correspondingly providing a first clamping groove and a second clamping groove on the base, and clamping the first clamping body in the first clamping groove and the second clamping body in the second clamping groove, the clamping connection between the shaft cover and the base can be realized, so that the shaft cover is detachable relative to the base. During the use of the foldable terminal, if the shaft cover needs to be replaced, only the shaft cover needs to be disassembled from the base, which is convenient for repairing or replacing the shaft cover without disassembling the entire rotating shaft, thereby improving the maintenance efficiency and reducing the maintenance cost.

[0043] When the shaft cover is a detachable structure, the shaft cover can be customized as a separate decorative part, so as to meet the needs of different users and improve the user experience. Exemplarily, the shaft cover can be set to different colors, or there are customized patterns on the outer surface of the shaft cover. Among them, the "outer surface" of the shaft cover refers to the surface of the shaft cover located outside the receiving groove.

[0044] Moreover, in this application, by arranging the first clamping body and the second clamping body on the opposite sides in the width direction of the shaft cover, the shaft cover and the base are clamped on both opposite sides in the width direction of the shaft cover assembly, so as to improve the connection stability between the shaft cover and the base, and further improve the structural stability of the shaft cover assembly.

[0059] The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0060] With the development of technology, the appearance (ID) form of electronic devices (such as mobile phones, tablet computers, etc.) has a tendency to develop from straight-bar mobile phones to foldable mobile phones. A foldable mobile phone has a large-area screen in the opened state, fully meeting the visual experience of consumers, and is small in volume and easy to carry in the closed state. The rotating shaft is the core component of a foldable terminal. During the assembly and use of a foldable terminal, the shaft cover of the rotating shaft may be scratched, damaged, etc. In the prior art, the shaft cover is difficult to disassemble, and generally the entire rotating shaft needs to be replaced during maintenance, which will increase the maintenance cost.

[0061] In order to reduce the maintenance or replacement cost of the shaft cover, the present application provides a shaft cover assembly. The shaft cover in the shaft cover assembly provided by the embodiments of the present application is detachable, and during maintenance, the shaft cover can be replaced separately, thereby reducing the maintenance cost.

[0062] Please refer to Figure 1 and Figure 2 , Figure 1 which are schematic structural diagrams of the foldable terminal 500 provided by the embodiments of the present application in the folded state, Figure 2 and

[0063] which are schematic structural diagrams of the foldable terminal 500 provided by the embodiments of the present application in the unfolded state. Figure 2 For convenience of description, the width direction of the foldable terminal 500 is defined as the X direction, the length direction of the foldable terminal 500 is defined as the Y direction, and the thickness direction of the foldable terminal 500 is defined as the Z direction. The X direction, Y direction, and Z direction are perpendicular to each other pairwise. It should be understood that the orientation terms such as "top" and "bottom" used in the description of the embodiments of the present application are mainly described based on the display orientation of the foldable terminal 500 in the attached

[0064] The foldable terminal 500 includes, but is not limited to, a cellphone, a notebook computer, a tablet personal computer, a laptop computer, a personal digital assistant, a wearable device, or a mobile device, etc. In the embodiments of the present application, the foldable terminal 500 is taken as an example of a foldable mobile phone for illustration.

[0065] ​The foldable terminal 500 shown in the embodiments of the present application is an electronic device that can be folded once. In some other embodiments, the foldable terminal 500 can also be an electronic device that can be folded multiple times (more than two times). At this time, the foldable terminal 500 can include multiple parts. Two adjacent parts can be relatively close to each other and folded until the foldable terminal 500 is in the folded state, and two adjacent parts can be relatively far away from each other and unfolded until the foldable terminal 500 is in the unfolded state.

[0066] Please refer to Figure 3 , Figure 3 is Figure 2 the exploded structural schematic diagram of the foldable terminal 500 shown.

[0067] The foldable terminal 500 includes a first housing 210, a second housing 220, a rotating shaft 400, and a display screen 300. The first housing 210 is provided with a first accommodating groove 230, and the second housing 220 is provided with a second accommodating groove 240. The first accommodating groove 230 and the second accommodating groove 240 communicate with each other to form the accommodating groove of the foldable terminal 500.

[0068] The rotating shaft 400 includes a shaft cover assembly 100, a first rotating assembly, and a second rotating assembly. The first rotating assembly and the second rotating assembly are respectively installed on the opposite sides of the shaft cover assembly 100 in the X direction and are rotatably connected to the shaft cover assembly 100. It should be noted that, Figure 3 the first rotating assembly and the second rotating assembly of the rotating shaft 400 are not shown. The first rotating assembly can include a swing arm, a wedge block, a door panel, etc. The second rotating assembly can include a swing arm, a wedge block, a door panel, etc. Among them, the swing arm can be any one or more of a main swing arm, a sub-swing arm, a synchronous swing arm, and a damping swing arm.

[0069] The rotating shaft 400 is disposed between the first housing 210 and the second housing 220 and is located in the accommodating groove. Among them, the first rotating assembly is connected to the first housing 210, and the second rotating assembly is connected to the second housing 220. When the first housing 210 rotates, it drives the first rotating assembly to rotate relative to the shaft cover assembly 100. When the second housing 220 rotates, it drives the second rotating assembly to rotate relative to the shaft cover assembly 100, so that the foldable terminal 500 can be switched between the folded state and the unfolded state.

[0070] The display screen 300 includes a first display portion 310, a second display portion 320, and a bendable portion 330. The bendable portion 330 is connected between the first display portion 310 and the second display portion 320, and the bendable portion 330 can be bent along the Y direction. The display screen 300 is mounted on a first housing 210, a second housing 220, and a rotating shaft 400. Among them, the first display portion 310 is mounted on the first housing 210, the second display portion 320 is mounted on the second housing 220, and the rotating shaft 400 is disposed opposite to the bendable portion 330. The first housing 210 and the second housing 220 can rotate relative to each other through the rotating shaft 400, thereby driving the first display portion 310 and the second display portion 320 to rotate relative to each other, and causing the bendable portion 330 to bend, so that the foldable terminal 500 can be switched between a folded state and an unfolded state.

[0071] When the first housing 210 and the second housing 220 rotate towards each other through the rotating shaft 400, they drive the display screen 300 to bend, so that the foldable terminal 500 is in a folded state. When the foldable terminal 500 is in the folded state, the bendable portion 330 of the display screen 300 bends, and the first display portion 310 and the second display portion 320 are disposed opposite to each other. At this time, the display screen 300 is located between the first housing 210 and the second housing 220, which can greatly reduce the probability of the display screen 300 being damaged and effectively protect the display screen 300.

[0072] When the first housing 210 and the second housing 220 rotate away from each other through the rotating shaft 400, they drive the first housing 210 and the second housing 220 to rotate away from each other, and drive the display screen 300 to unfold, so that the foldable terminal 500 is in an unfolded state. When the foldable terminal 500 is in the unfolded state, the bendable portion 330 unfolds, and the first display portion 310 and the second display portion 320 are relatively unfolded. At this time, the display surface of the display screen 300 is substantially flat, having a large display area, thereby realizing the large-screen display of the foldable terminal 500 and improving the user experience.

[0073] Please refer to Figure 3 and Figure 4 , Figure 4 which Figure 3 is a partial exploded structural schematic diagram of the rotating shaft 400 in the foldable terminal 500 shown.

[0074] The rotating shaft 400 includes a shaft cover assembly 100 and an intermediate door panel 410. The shaft cover assembly 100 is provided with a receiving groove 107. The opening of the receiving groove 107 is located on the top surface 101 of the shaft cover assembly 100. The intermediate door panel 410 is installed in the receiving groove 107 and fixedly connected to the shaft cover assembly 100. In this embodiment, the intermediate door panel 410 and the shaft cover assembly 100 are fixedly connected by bolts. In other embodiments, the intermediate door panel 410 can also be fixedly connected to the shaft cover assembly 100 by bonding, welding or other means.

[0075] The top surface of the intermediate door panel 410 is flush with the top surface 101 of the shaft cover assembly 100 and is substantially in the same plane. The display screen 300 is provided on the top surface of the rotating shaft 400, that is, the display screen 300 is provided on the top surface of the intermediate door panel 410 and the top surface 101 of the shaft cover assembly 100. When the foldable terminal 500 is in the unfolded state, the intermediate door panel 410 and the shaft cover assembly 100 jointly support the bendable part of the display screen 300. In this embodiment, by making the top surface 101 of the intermediate door panel 410 flush with the top surface 101 of the shaft cover assembly 100 when the foldable terminal 500 is in the unfolded state, the support performance for the display screen 300 can be improved, and the flatness of the display screen 300 when the foldable terminal 500 is in the unfolded state can be improved.

[0076] Please refer to Figure 5 and Figure 6 , Figure 5 is Figure 4 the schematic structural diagram of the shaft cover assembly 100 in the rotating shaft 400 shown in Figure 6 is Figure 5 the exploded structural diagram of the shaft cover assembly 100 shown in

[0077] The shaft cover assembly 100 includes a shaft cover 20 and a base 10. The shaft cover 20 includes a cover body 21 and a clamping body 22. The cover body 21 is provided with an installation groove 201. The clamping body 22 is connected to the side surface of the cover body 21 and faces the installation groove 201. The side surface of the base 10 is provided with a clamping groove 11. The base 10 is installed in the installation groove 201, the side surface of the base 10 faces the side wall of the installation groove 201, and the clamping body 22 is clamped in the clamping groove 11. The first rotating assembly and the second rotating assembly are both installed on the base 10 and are respectively located on opposite sides in the width direction of the base 10, and both the first rotating assembly and the second rotating assembly are rotatably connected to the base 10.

[0078] In this embodiment, by providing a clamping body 22 on the shaft cover 20, providing a clamping groove 11 on the base 10, and clamping the clamping body 22 in the clamping groove 11, the clamping connection between the shaft cover 20 and the base 10 can be achieved, making the shaft cover 20 detachable relative to the base 10. During the use of the foldable terminal 500, if the shaft cover 20 needs to be repaired or replaced, only the shaft cover 20 needs to be detached from the base 10, which is convenient for repairing or replacing the shaft cover 20 without detaching the entire rotating shaft 400, thereby reducing the repair cost.

[0079] Please refer to Figure 7 , Figure 7 is Figure 6 a schematic structural view of the base 10 in the shaft cover assembly 100 shown in another angle.

[0080] In this embodiment, the base 10 has a long strip structure, and the length direction of the base 10 is parallel to the Y direction. The base 10 includes a top surface 101, a bottom surface 102, a first outer side surface 103, a second outer side surface 104, a first end surface 105, and a second end surface 106. The top surface 101 and the bottom surface 102 are arranged opposite to each other along the thickness direction of the base 10, that is, opposite to each other along the Z direction. The first outer side surface 103 and the second outer side surface 104 are arranged opposite to each other along the width direction of the base 10, that is, opposite to each other along the X direction, and both the first outer side surface 103 and the second outer side surface 104 are connected between the top surface 101 and the bottom surface 102. The first end surface 105 and the second end surface 106 are arranged opposite to each other along the length direction of the base 10 and are connected between the top surface 101 and the bottom surface 102. The first outer side surface 103, the first end surface 105, the second outer side surface 104, and the second end surface 106 are connected end to end to jointly form the outer peripheral surface of the base 10.

[0081] The base 10 is provided with a receiving groove 107. The opening of the receiving groove 107 is located on the top surface 101, and the receiving groove 107 is arranged along the Y direction. The middle door panel 410 of the rotating shaft 400 is installed in the receiving groove 107. And, the top surface 101 of the middle door panel 410 is flush with the top surface 101 of the base 10. The bottom wall of the receiving groove 107 is provided with a bolt hole 108. The bolt hole 108 is used for installing a bolt to achieve the fixed connection between the base 10 and the middle door panel 410.

[0082] The outer peripheral surface of the base 10 is provided with a clamping groove 11. The clamping groove 11 is used for clamping connection with the shaft cover 20.

When the clamping groove 11 is one, the clamping groove 11 can be provided on the first outer side surface 103, or the second outer side surface 104, or the first end surface 105, or the second end surface 106. When the clamping groove 11 is multiple, the multiple clamping grooves 11 are arranged at intervals along the outer peripheral surface of the base 10, and each clamping groove 11 is used for clamping connection with the shaft cover 20 to improve the connection stability between the base 10 and the shaft cover 20.

[0083] In this embodiment, there are multiple card slots 11. At least one of the multiple card slots 11 is provided on the first outer side surface 103, and at least one card slot 11 is provided on the second outer side surface 104. That is to say, both the first outer side surface 103 and the second outer side surface 104 are provided with card slots 11. Among them, the card slot 11 provided on the first outer side surface 103 is the first card slot 12, and the card slot 11 provided on the second outer side surface 104 is the second card slot 13.

[0084] Please refer to Figure 8 , Figure 8 is Figure 7 the schematic cross-sectional structure diagram of the shown base 10 along the A-A direction.

[0085] The first card slot 12 includes a first sub-slot 121 and a second sub-slot 122. The first sub-slot 121 is provided on the first outer side surface 103. The second sub-slot 122 is provided on the bottom wall of the first sub-slot 121 and is close to the top surface 101. The second sub-slot 122 communicates with the first sub-slot 121 and is connected to the bottom wall of the first sub-slot 121 through a first guiding arc surface 123. Among them, the first guiding arc surface 123 is arc-shaped. In this embodiment, the first guiding arc surface 123 is formed by a chamfering process. In other embodiments, the first guiding arc surface 123 can also be formed by other processes. It can be understood that both the first sub-slot 121 and the second sub-slot 122 are provided on the first outer side surface 103, and the depth of the second sub-slot 122 is greater than the depth of the first sub-slot 121.

[0086] In one implementation manner, the first card slot 12 can also only include the second sub-slot 122. That is to say, the first card slot 12 is provided on the first outer side surface 103 and extends towards the inside of the base 10.

[0087] In this embodiment, there are two first card slots 12. The two first card slots 12 are arranged at intervals along the length direction of the first outer side surface 103. In other embodiments, the first card slot 12 can also be one, three or more than four. The number of the first card slots 12 is not specifically limited here.

[0088] The second card slot 13 and the first card slot 12 are mirror-symmetrical structures to each other. The second card slot 13 includes a third sub-slot 131 and a fourth sub-slot 132. The third sub-slot 131 is provided on the second outer side surface 104. The fourth sub-slot 132 is provided on the bottom wall of the third sub-slot 131 and is close to the top surface 101. The fourth sub-slot 132 communicates with the third sub-slot 131 and is connected to the bottom wall of the third sub-slot 131 through a second guiding arc surface 133.

[0089] In this embodiment, there are two second card slots 13. The two second card slots 13 are arranged at intervals along the length direction of the second outer side surface 104. In other embodiments, the second card slot 13 can also be one, three or more than four. The number of the second card slots 13 is not specifically limited here.

[0090] As Figure 7 shown, in this embodiment, the base 10 includes a first sub-base 15, a second sub-base 16, and a third sub-base 17. The first sub-base 15, the second sub-base 16, and the third sub-base 17 are arranged in sequence along the Y direction. Among them, the first sub-base 15 is located on one side in the Y-axis direction, the third sub-base 17 is located on the positive Y-axis direction side, and the third sub-base 17 and the first sub-base 15 are symmetrically arranged. Both the first sub-base 15 and the third sub-base 17 are used to install the rotating components of the rotating shaft 400, such as swing arms, wedge blocks, door panels and other structures. The second sub-base 16 is located between the first base 10 and the third sub-base 17. The second sub-base 16 is used to install the flexible circuit board of the foldable terminal 500 to realize the electrical connection of the electronic devices located on the opposite sides in the width direction of the rotating shaft 400. That is to say, in this embodiment, the base 10 is a split structure. In other embodiments, the base 10 can also be an integrally formed structure.

[0091] As Figure 6 and Figure 7 shown, one of the first card slots 12 is provided on the first sub-base 15, and the other first card slot 12 is provided on the third sub-base 17. One of the second card slots 13 is provided on the first sub-base 15 and is disposed opposite to the first card slot 12 provided on the first sub-base 15. The other second card slot 13 is provided on the third sub-base 17 and is disposed opposite to the first card slot 12 provided on the third sub-base 17.

[0092] The base 10 is further provided with an extension portion 14. The extension portion 14 is connected to the outer peripheral surface of the base 10 and extends in a direction away from the outer peripheral surface. It can be understood that the outer peripheral surface of the extension portion 14 protrudes from the outer peripheral surface of the base 10. That is to say, the outer peripheral surface of the extension portion 14 protrudes from the first outer side surface 103, the second outer side surface 104, the first end surface 105, and the second end surface 106. In this embodiment, the extension portion 14 is provided on the outer peripheries of the first sub-base 15 and the third sub-base 17. That is to say, the extension portion 14 surrounds the entire outer peripheral surface of the base 10, and an avoidance notch is provided on the side surface of the second sub-base 16. The wiring of the flexible circuit board provided on the second sub-base 16 passes through the avoidance notch and is electrically connected to the electronic devices provided in the first housing 210 and the second housing 220.

[0093] In this embodiment, the top surface of the extension portion 14 is flush with the first top surface 101 to ensure that the top surface of the base 10 is a plane, thereby improving the supporting effect on the display screen 300.

[0094] Please refer to Figure 9 and Figure 10 , Figure 9 which Figure 6 is the structural schematic diagram of the shaft cover 20 in the shaft cover assembly shown Figure 10 and Figure 5Schematic cross-sectional structure diagram of the shaft cover assembly 100 shown in the B-B direction.

[0095] The shaft cover 20 includes a cover body 21 and a clamping body 22. The cover body 21 includes a bottom plate 211, a first side plate 212, a second side plate 213, a first end plate 214, and a second end plate 215. In this embodiment, the bottom plate 211 is rectangular. The first side plate 212, the first end plate 214, the second side plate 213, and the second end plate 215 are connected end to end, and are all connected to the outer peripheral edge of the bottom plate 211, and together with the bottom plate 211, they enclose an installation groove 201. The opening of the installation groove 201 is arranged opposite to the bottom plate 211. Among them, the first side plate 212 and the second side plate 213 are arranged opposite to each other in the X direction, and the first end plate 214 and the second end plate 215 are arranged opposite to each other in the Y direction.

[0096] In this embodiment, the heights of the first side plate 212 and the second side plate 213 are both smaller than the heights of the first end plate 214 and the second end plate 215. That is, the tops of the first side plate 212 and the second side plate 213 are both located on the side of the tops of the first end plate 214 and the second end plate 215 close to the bottom plate 211, that is, the tops of the first side plate 212 and the second side plate 213 are both located on the negative Z-axis side of the tops of the first end plate 214 and the second end plate 215. In other embodiments, the heights of the first side plate 212, the second side plate 213, the first end plate 214, and the second end plate 215 may also be the same or approximately the same. That is, the top surfaces of the first side plate 212, the second side plate 213, the first end plate 214, and the second end plate 215 are flush or approximately flush.

[0097] The clamping body 22 is connected to the cover body 21 and is arranged corresponding to the clamping groove 11. The clamping body 22 is used to engage with the clamping groove 11 so that the shaft cover 20 is clamped and connected to the base 10.

[0098] Among them, the clamping body 22 can be one or multiple. When the clamping body 22 is one, the clamping body 22 can be connected to the first side plate 212, or the second side plate 213, or the first end plate 214, or the second end plate 215, as long as the clamping body 22 is arranged corresponding to the clamping groove 11. When the clamping body 22 is multiple, the multiple clamping bodies 22 are arranged at intervals along the side plates of the cover body 21 and are arranged in one-to-one correspondence with the clamping grooves 11. Each clamping body 22 engages with the corresponding clamping groove 11 to improve the connection stability between the shaft cover 20 and the base 10.

[0099] In this embodiment, there are four clamping bodies 22. Two of the four clamping bodies 22 are connected to the first side plate 212, and the other two clamping bodies 22 are connected to the second side plate 213. Among them, the clamping body 22 connected to the first side plate 212 is the first clamping body 23, and the clamping body 22 connected to the second side plate 213 is the second clamping body 24. That is to say, the clamping body 22 includes two first clamping bodies 23 and two second clamping bodies 24. The two first clamping bodies 23 are connected to the first side plate 212, and the two second clamping bodies 24 are connected to the second side plate 213.

[0100] As Figure 9 shown, the first clamping body 23 includes a first connecting portion 231 and a first clamping portion 232. The first connecting portion 231 includes a first surface 233, a second surface 234, a first top surface 235 and a first bottom surface 236. The first surface 233 and the second surface 234 are arranged back to back along the thickness direction of the first connecting portion 231. The first top surface 235 and the first bottom surface 236 are arranged back to back along the height direction of the first connecting portion 231 and are connected between the first surface 233 and the second surface 234. That is, the first top surface 235 and the first bottom surface 236 are arranged back to back along the extending direction of the first connecting portion 231.

[0101] The first clamping portion 232 is connected to the first surface 233 and extends in a direction away from the first surface 233. The first clamping portion 232 can be understood as a protrusion protruding from the first surface 233. In this embodiment, the first clamping portion 232 is close to the first top surface 235, and the top surface 101 of the first clamping portion 232 is flush with the first top surface 235 of the first connecting portion 231. The top surface 101 of the first clamping portion 232 and the first top surface 235 together form the top surface 101 of the first clamping body 23 and are used to be arranged opposite to the extending portion 14 of the base 10.

[0102] In this embodiment, the end face of the first clamping portion 232 is arc-shaped. In other embodiments, the end face of the first clamping body 23 can also be a plane. Among them, the end face of the first clamping portion 232 refers to the surface of the first clamping portion 232 away from the first connecting portion 231 in the extending direction of the first clamping portion 232.

[0103] In this embodiment, the end face of the first clamping portion 232 is arc-connected to the first surface 233, so as to avoid stress concentration and improve the structural strength of the first clamping body 23.

[0104] Among them, a first notch 237 is provided on the first surface 233. The first notch 237 penetrates the first connecting portion 231 along the width direction of the first connecting portion 231. In this embodiment, the inner surface of the first notch 237 is an arc surface, so that the inner wall of the first notch 237 is uniformly stressed, stress concentration can be avoided, and the structural strength of the first clamping body 23 can be further improved.

[0105] It can be understood that the first notch 237 divides the first clamping body 23 into a first part 238 and a second part 239, and the first part 238 and the second part 239 are connected along the height direction of the first clamping body 23. Among them, the first part 238 is located on the side of the first notch 237 close to the first top surface 235, and the second part 239 is located on the side of the second notch 247 close to the first bottom surface 236.

[0106] The first clamping body 23 is fixedly connected to the first side plate 212. Among them, the width direction of the first clamping body 23 is parallel to the length direction of the shaft cover 20, that is, parallel to the Y direction. The height direction of the first clamping body 23 is parallel to the thickness direction of the shaft cover 20, that is, parallel to the Z direction. The thickness direction of the first clamping body 23 is parallel to the X direction. The first bottom surface 236 is connected to the top surface 101 of the first side plate 212, the first surface 233 faces the installation groove 201, and the second surface 234 is flush or substantially flush with the outer surface of the first side plate 212. It can be understood that the first clamping portion 232 extends towards the inside of the installation groove 201, and the opening of the first notch 237 faces the inside of the installation groove 201.

[0107] In this embodiment, the structures of the two first clamping bodies 23 are the same. The two first clamping bodies 23 are arranged at intervals along the length direction of the first side plate 212, and each first clamping body 23 is correspondingly arranged with the corresponding first card slot 12. In other embodiments, the structures of the two first clamping bodies 23 may also be similar or different, as long as the structure of each first clamping body 23 matches the structure of the corresponding first card slot 12. Here, "matching" means that the first clamping body 23 can be clamped in the first card slot 12.

[0108] The second clamping body 24 and the first clamping body 23 are mirror-symmetrical structures to each other. The second clamping body 24 includes a second connecting portion 241 and a second clamping portion 242. The second connecting portion 241 includes a third surface 243, a fourth surface 244, a second top surface 245 and a second bottom surface 246. The third surface 243 and the fourth surface 244 are arranged opposite to each other along the thickness direction of the second connecting portion 241. The second top surface 245 and the second bottom surface 246 are arranged opposite to each other along the height direction of the second connecting portion 241 and are connected between the third surface 243 and the fourth surface 244.

[0109] The second clamping portion 242 is connected to the third surface 243 and extends in a direction away from the third surface 243. The second clamping portion 242 can be understood as a protrusion protruding from the third surface 243. In this embodiment, the second clamping portion 242 is close to the second top surface 245, and the top surface 101 of the second clamping portion 242 is flush with the second top surface 245 of the second connecting portion 241. The top surface 101 of the second clamping portion 242 and the second top surface 245 together form the top surface 101 of the second clamping body 24 and are used to be disposed opposite to the extension portion 14 of the base 10.

[0110] The third surface 243 is provided with a second notch 247. The second notch 247 penetrates the second connecting portion 241 along the width direction of the second connecting portion 241. It can be understood that the second notch 247 divides the second clamping body 24 into a third portion 248 and a fourth portion 249, and the third portion 248 and the fourth portion 249 are connected along the height direction of the second clamping body 24. Among them, the third portion 248 is located on the side of the second notch 247 close to the second top surface 245, and the fourth portion 249 is located on the side of the second notch 247 close to the second bottom surface 246.

[0111] The second clamping body 24 is fixedly connected to the second side plate 213. The second bottom surface 246 is connected to the top surface 101 of the second side plate 213, the second surface 234 faces the mounting groove 201, and the second surface 234 is flush or substantially flush with the outer surface of the second side plate 213. It can be understood that the second clamping portion 242 extends into the mounting groove 201, and the opening of the second notch 247 faces into the mounting groove 201.

[0112] In this embodiment, the structures of the two second clamping bodies 24 are the same. The two second clamping bodies 24 are arranged at intervals along the length direction of the second side plate 213, and each second clamping body 24 is arranged corresponding to the corresponding second card slot 13. In other embodiments, the structures of the two second clamping bodies 24 may also be similar or different, as long as the structure of each second clamping body 24 matches the structure of the corresponding second card slot 13. Here, "matching" means that the second clamping body 24 can be clamped in the second card slot 13.

[0113] In this embodiment, the second clamping body 24 and the first clamping body 23 are arranged opposite to each other along the X direction. In other embodiments, the second clamping body 24 and the first clamping body 23 may also be arranged offset along the X direction. The position of the second clamping body 24 is not specifically limited here, as long as the second clamping body 24 can be engaged with the second card slot 13.

[0114] Such as Figure 5 and Figure 10As shown, the shaft cover 20 is sleeved on the outer peripheral surface of the base 10. That is, the base 10 is installed in the installation groove 201 of the shaft cover 20. Among them, the first side plate 212 faces the first outer side surface 103, the second side plate 213 faces the second outer side surface 104, the first end plate 214 faces the first end surface 105, and the second end plate 215 faces the second end surface 106. The first clamping body 23 is correspondingly arranged with the first clamping groove 12. The first connecting portion 231 of the first clamping body 23 is located in the first sub-groove 121, and the first clamping portion 232 is clamped in the second sub-groove 122. The top surface 101 of the first clamping body 23 and the extension portion 14 are arranged opposite to each other in the Z direction. That is to say, at least part of the positive projection of the extension portion 14 in the Z direction coincides with the first clamping body 23. In this embodiment, the top surface 101 of the first clamping body 23 is parallel to the extension portion 14 and in contact with each other. In other embodiments, there may also be a small gap between the first clamping body 23 and the extension portion 14.

[0115] The second clamping body 24 is correspondingly arranged with the second clamping groove 13 one by one, and each second clamping body 24 is clamped in the corresponding second clamping groove 13. The second connecting portion 241 of the second clamping body 24 is located in the third sub-groove 131, and the second clamping portion 242 is clamped in the fourth sub-groove 132. The top surface 101 of the second clamping body 24 and the extension portion 14 are arranged opposite to each other in the Z direction. That is to say, at least part of the positive projection of the extension portion 14 in the Z direction coincides with the second clamping body 24. In this embodiment, the top surface 101 of the second clamping body 24 is parallel to the extension portion 14 and in contact with each other. In other embodiments, there may also be a small gap between the second clamping body 24 and the extension portion 14.

[0116] In this embodiment, by providing the first clamping body 23 and the second clamping body 24 on the shaft cover 20, providing the first clamping groove 12 and the second clamping groove 13 on the base 10, and clamping the first clamping body 23 in the first clamping groove 12 and the second clamping body 24 in the second clamping groove 13, the clamping connection between the shaft cover 20 and the base 10 can be realized, making the shaft cover 20 detachable relative to the base 10. During the use of the foldable terminal 500, if the shaft cover needs to be repaired or replaced, only the shaft cover 20 needs to be detached from the base 10, which is convenient for repairing or replacing the shaft cover 20 without disassembling the entire rotating shaft 400, thereby improving the repair efficiency and reducing the repair cost.

[0117] When the shaft cover 20 is a detachable structure, the shaft cover 20 can be customized as a separate decorative part, so as to meet the needs of different users and improve the user experience. Exemplarily, the shaft cover 20 can be set to different colors, or there are customized patterns on the appearance surface of the shaft cover 20. Among them, the "appearance surface" of the shaft cover 20 refers to the surface of the shaft cover 20 located outside the installation groove 201.

[0118] Moreover, in this embodiment, by arranging the first clamping body 23 and the second clamping body 24 on opposite sides in the width direction of the shaft cover 20, and correspondingly arranging a first clamping groove 12 and a second clamping groove 13 on the base 10, the shaft cover 20 and the base 10 are clamped on both opposite sides in the width direction of the shaft cover assembly 100, thereby improving the connection stability between the shaft cover 20 and the base 10, and further improving the structural stability of the shaft cover assembly 100.

[0119] Meanwhile, in this embodiment, by symmetrically arranging the first clamping body 23 and the second clamping body 24 along the width direction of the shaft cover assembly 100, when the shaft cover 20 is being installed on the base 10 or removed from the base 10, the forces on both opposite sides in the width direction are uniform, thereby reducing or even avoiding deformation of the shaft cover 20 during installation or removal.

[0120] Moreover, in this embodiment, by arranging a plurality of first clamping bodies 23 and second clamping bodies 24 along the length direction of the cover body 21, and correspondingly arranging a plurality of first clamping grooves 12 and a plurality of second clamping grooves 13 on the base 10, the base 10 and the shaft cover 20 can be clamped at multiple positions in the length direction of the shaft cover assembly 100, thereby improving the connection stability between the shaft cover 20 and the base 10.

[0121] In this embodiment, by setting the depth of the second sub-groove 122 to be greater than the depth of the first sub-groove 121, and clamping the first clamping portion 232 in the second sub-groove 122, the first clamping portion 232 can be prevented from disengaging from the second sub-groove 122, thereby improving the clamping stability between the first clamping body 23 and the first clamping groove 12, and further improving the connection stability between the shaft cover 20 and the base 10.

[0122] In addition, in this embodiment, by providing an extension portion 14 on the base 10, a limiting effect can be exerted on the first clamping body 23 and the second clamping body 24 in the Z direction, preventing the first clamping body 23 and the second clamping body 24 from moving in the positive Z-axis direction, thereby preventing the shaft cover 20 from moving in the positive Z direction, and further improving the connection stability between the shaft cover 20 and the base 10.

[0123] Please refer to Figure 11 , Figure 11 which Figure 10 is a schematic cross-sectional structure diagram of the shaft cover assembly 100 in another state. Among them, Figure 11 the shown shaft cover assembly 100 can be a schematic structure diagram during installation or a schematic structure diagram during removal.

[0124] The installation process of the shaft cover assembly 100 includes: First, sleeved the shaft cover 20 from the bottom of the base 10 onto the outer periphery of the base 10. The bottom surface 102 of the base 10 is disposed opposite to the bottom plate 211 of the shaft cover 20, and at least a part of the base 10 is located within the installation groove 201. The first outer side surface 103 of the base 10 is disposed opposite to the first side plate 212. The first clamping body 23 faces the first clamping groove 12, and the first clamping portion 232 abuts against the bottom wall of the first sub-groove 121, causing the first clamping body 23 to deform. The second outer side surface 104 of the base 10 is disposed opposite to the second side plate 213. The second clamping body 24 faces the second clamping groove 13, and the second clamping portion 242 abuts against the bottom wall of the third sub-groove 131, causing the second clamping body 24 to deform.

[0125] Then, push the shaft cover 20 in the direction of the base 10, causing the shaft cover 20 to move in the direction close to the base 10. When the shaft cover 20 moves in the direction close to the base 10, the first clamping body 23 moves in the direction close to the base 10, that is, moves in the positive direction of the Z axis, causing the first clamping portion 232 to slide into the second sub-groove 122 along the first guiding arc surface 123, so that the deformation of the first clamping body 23 is restored and is clamped with the first clamping groove 12. At the same time, when the shaft cover 20 moves in the direction close to the base 10, the second clamping body 24 moves in the positive direction of the Z axis, and the second clamping portion 242 slides into the fourth sub-groove 132 along the second guiding arc surface 133, so that the deformation of the second clamping body 24 is restored and is clamped with the second clamping groove 13, and further the shaft cover 20 is clamped and connected with the base 10.

[0126] The disassembly process of the shaft cover assembly 100 includes: applying a force to the shaft cover 20 in the direction away from the base 10, causing the first clamping portion 232 to slide along the first guiding arc surface 123, so as to abut against the first abutting portion, causing the first clamping body 23 to deform in the direction away from the base 10. At the same time, when the shaft cover 20 moves in the direction away from the base 10, the second clamping portion 242 slides along the second guiding arc surface 133, so as to abut against the second abutting portion, causing the second clamping body 24 to deform in the direction away from the base 10.

[0127] Continue to apply a force to the shaft cover 20 in the direction away from the base 10, driving the first clamping body 23 to move in the direction away from the base 10, and further causing the first abutting portion to slide out of the second sub-groove 122, so that the first clamping body 23 is unlocked from the first clamping groove 12. At the same time, the shaft cover 20 drives the second clamping body 24 to move in the direction away from the base 10, and further causes the second abutting portion to slide out of the fourth sub-groove 132, so that the second clamping body 24 is unlocked from the second clamping groove 13, thereby causing the shaft cover 20 to disengage from the base 10.

[0128] In this embodiment, by setting the end face of the first clamping portion 232 as an arc surface, and connecting the bottom wall of the first sub-slot 121 and the inner wall of the second sub-slot 122 through a first guiding arc surface 123, when the shaft cover 20 is being installed onto the base 10, the end face of the first clamping portion 232 can slide in an arc along the first guiding arc surface 123 into the second sub-slot 122. Thereby, the smoothness of the installation process of the shaft cover assembly 100 can be improved, and the difficulty of installing the shaft cover 20 onto the base 10 can be reduced. Meanwhile, during the disassembly process of the shaft cover 20, the end of the first clamping portion 232 can slide out of the second sub-slot 122 along the first guiding arc surface 123. Thereby, the smoothness of the disassembly process of the shaft cover assembly 100 can be improved, the difficulty of disassembling the shaft cover 20 can be reduced, and the maintenance efficiency of the shaft cover assembly 100 can be enhanced.

[0129] Moreover, in this embodiment, by setting the end face of the second clamping portion 242 as an arc surface, and connecting the bottom wall of the third sub-slot 131 and the inner wall of the fourth sub-slot 132 through a second guiding arc surface 133, when the shaft cover 20 is being installed onto the base 10, the end face of the second clamping portion 242 can slide in an arc along the second guiding arc surface 133 into the fourth sub-slot 132. Thereby, the smoothness of the installation process of the shaft cover assembly 100 can be further improved, and the difficulty of installing the shaft cover 20 onto the base 10 can be reduced. Meanwhile, during the disassembly process of the shaft cover 20, the end of the second clamping portion 242 can slide out of the fourth sub-slot 132 along the second guiding arc surface 133. Thereby, the smoothness of the disassembly process of the shaft cover assembly 100 can be further improved, and the difficulty of disassembling the shaft cover 20 can be reduced.

[0130] It can be understood that during the disassembly and installation processes of the shaft cover assembly 100, the base 10 abuts against the first clamping portion 232 and the second clamping portion 242, causing the first clamping body 23 and the second clamping body 24 to deform in a direction away from the base 10. In this embodiment, by providing a first notch 237 in the first clamping body 23, the abutting force received by the first clamping body 23 is concentrated at the first notch 237, so that the deformation amount of the second part 239 is smaller than that of the first part 238, that is, the deformation amount of the second part 239 can be reduced. Meanwhile, in this embodiment, by providing a second notch 247 in the second clamping body 24, the abutting force received by the second clamping body 24 is concentrated at the second notch 247, so that the deformation amount of the fourth part 249 is smaller than that of the third part 248, that is, the deformation of the fourth part 249 can be reduced.

[0131] In other words, in this embodiment, by providing the first notch 237 in the first clamping body 23, the stress and deformation amount received by the second part 239 can be reduced, thereby reducing the stress and deformation amount received by the first side plate 212. At the same time, by providing the second notch 247 in the second clamping body 24, the stress and deformation amount received by the fourth part 249 can be reduced, thereby reducing the stress and deformation amount received by the second side plate 213, and further reducing the stress and deformation amount received by the bottom plate 211. That is to say, in this embodiment, by providing the first notch 237 in the first clamping body 23 and the second notch 247 in the second clamping body 24, the stress and deformation amount received by the first side plate 212, the second side plate 213, and the bottom plate 211 can be reduced, thereby reducing or even avoiding the generation of convex prints or dents on the appearance surface of the shaft cover 20, and further improving the consistency of the appearance of the shaft cover 20 and enhancing the user experience.

[0132] As Figure 9 shown, the shaft cover 20 further includes a positioning block 25. The positioning block 25 includes a first positioning block 251 and a second positioning block 252. The first positioning block 251 is connected to the first side plate 212 along the Z direction, that is, the first positioning block 251 is connected to the top of the first side plate 212. The first positioning block 251 is spaced apart from the first clamping body 23. The second positioning block 252 is connected to the second side plate 213 along the Z direction, that is, the second positioning block 252 is connected to the top of the second side plate 213. The second positioning block 252 is spaced apart from the second clamping body 24. In this embodiment, the second positioning block 252 and the first positioning block 251 are arranged opposite to and parallel to each other along the X direction. In other embodiments, the second positioning block 252 and the first positioning block 251 may also be arranged offset from each other along the X direction.

[0133] In this embodiment, both the first positioning block 251 and the second positioning block 252 are two. The two first positioning blocks 251 are spaced apart from each other along the Y direction on the top of the first side plate 212, and one of the first positioning blocks 251 is correspondingly arranged with the first sub-base 15, and the other first positioning block 251 is correspondingly arranged with the third sub-base 17. The two second positioning blocks 252 are spaced apart from each other along the Y direction on the top of the second side plate 213, and one of the second positioning blocks 252 is correspondingly arranged with the first sub-base 15, and the other second positioning block 252 is correspondingly arranged with the third sub-base 17.

[0134] Please refer to Figure 9 and Figure 12 , Figure 12 which Figure 5 is the schematic cross-sectional structure diagram of the shaft cover assembly 100 along the C-C direction as shown.

[0135] When the shaft cover 20 is installed on the base 10, the first positioning block 251 is disposed opposite to the first outer side surface 103 of the base 10, and the second positioning block 252 is disposed opposite to the second outer side surface 104 of the base 10. In this embodiment, the first positioning block 251 contacts the first outer side surface 103, and the second positioning block 252 contacts the second outer side surface 104. In other embodiments, the first positioning block 251 may also abut against the first outer side surface 103, and the second positioning block 252 may also abut against the second outer side surface 104.

[0136] In this embodiment, by providing the first positioning block 251 and the second positioning block 252 on the shaft cover 20, the mating area between the shaft cover 20 and the base 10 can be increased, thereby improving the connection stability between the shaft cover 20 and the base 10. Moreover, in this embodiment, by respectively disposing the first positioning block 251 and the second positioning block 252 on opposite sides in the width direction of the shaft cover 20, the shaft cover 20 can be limited in the X direction, thereby reducing or even avoiding the shaft cover 20 from shaking in the X direction, and further improving the connection stability between the shaft cover 20 and the base 10.

[0137] During the process of installing the shaft cover 20 on the base 10, the shaft cover 20 can be first sleeved on the outer periphery of the base 10 from the bottom of the base 10, and the first positioning block 251 is disposed opposite to the first outer side surface 103, and the second positioning block 252 is disposed opposite to the second outer side surface 104. Then, a force is applied to the shaft cover 20 in the direction towards the base 10, so that the first engaging body 23 is engaged with the first engaging groove 12, and the second engaging body 24 is engaged with the second engaging groove 13.

[0138] In this embodiment, by respectively providing the first positioning block 251 and the second positioning block 252 on opposite sides in the width direction of the shaft cover 20, during the process of installing the shaft cover 20 on the base 10, the first positioning block 251 and the second positioning block 252 play a positioning role for the shaft cover 20, thereby avoiding the shaft cover 20 from shaking in the X direction, enabling the first engaging body 23 to be accurately engaged with the first engaging groove 12, and enabling the second engaging body 24 to be accurately engaged with the second engaging groove 13. Furthermore, the installation difficulty of installing the shaft cover 20 onto the base 10 can be reduced, and the connection stability between the shaft cover 20 and the base 10 can be improved.

[0139] As Figure 9 shown, the cover body 21 is further provided with a disassembly opening 26. The disassembly opening 26 is provided on the first end plate 214 or the second end plate 215. Alternatively, both the first end plate 214 and the second end plate 215 are provided with the disassembly opening 26. When it is necessary to disassemble the shaft cover 20 from the base 10, by disposing a disassembly tool in the disassembly opening 26 and applying a force to the shaft cover 20 in the direction away from the base 10, the first engaging body 23 can be unlocked from the first engaging groove 12, and the second engaging body 24 can be unlocked from the second engaging groove 13, so that the shaft cover 20 is separated from the base 10, and the disassembly of the shaft cover 20 is achieved.

[0140] In this embodiment, there are two disassembly openings 26. The two disassembly openings 26 are the first disassembly opening 261 and the second disassembly opening 262 respectively. The first disassembly opening 261 is provided on the first end plate 214. In this embodiment, the first disassembly opening 261 is a "U" - shaped groove. The first disassembly opening 261 is provided at the top of the first end plate 214, penetrates through the top surface 101 of the first end plate 214, and the first disassembly opening 261 penetrates through the inner surface and the outer surface of the first end plate 214. Among them, the "outer surface of the first end plate 214" refers to the surface of the first end plate 214 located outside the receiving groove 107, and the "inner surface of the first end plate 214" refers to the surface of the first end plate 214 facing the receiving groove 107. In this embodiment, by making the first disassembly opening 261 penetrate through the outer surface of the first end plate 214, during the process of disassembling the shaft cover 20, the disassembly tool can be inserted into the first disassembly opening 261 from the outer surface of the first end plate 214 to achieve the disassembly of the shaft cover 20, so that the shaft cover 20 can be conveniently disassembled, and the disassembly efficiency can be improved, thereby improving the maintenance efficiency.

[0141] In other embodiments, the first disassembly opening 261 can also be a through - hole. The first disassembly opening 261 is provided on the first end plate 214 and penetrates through the inner surface and the outer surface of the first end plate 214. Or, the first disassembly opening 261 can also be a blind hole. The first disassembly opening 261 is provided on the first end plate 214 and penetrates through the outer surface of the first end plate 214. Here, no specific restrictions are made on the position and shape of the first disassembly opening 261, as long as the first disassembly opening 261 penetrates through the outer surface of the first end plate 214.

[0142] In one implementation manner, the first disassembly opening 261 can be the gap between the first end plate 214 and the extension part 14. During the disassembly process of the shaft cover 20, the disassembly tool can be inserted into the gap between the first end plate 214 and the extension part 14, and then a force is applied to the shaft cover 20, so that the clamping body 22 is disengaged from the clamping groove 11 to achieve the disassembly of the shaft cover 20.

[0143] In this embodiment, the first disassembly opening 261 is located at the central position of the first end plate 214 along the X - direction. Of course, there can also be a small deviation between the first disassembly opening 261 and the central position of the first end plate 214 along the X - direction. That is to say, the distance from the first disassembly opening 261 to the first side plate 212 is equal to or approximately equal to the distance from the first disassembly opening 261 to the second side plate 213.

[0144] Please combine Figure 1When the shaft cover assembly 100 is applied to the foldable terminal 500, the first disassembly opening 261 exposes the outside of the foldable terminal 500. Exemplarily, both the first housing 210 and the second housing 220 are provided with notches, and the notch of the first housing 210 and the notch of the second housing 220 form an avoidance opening. The avoidance opening is disposed opposite to the first disassembly opening 261, so that the first disassembly opening 261 exposes the foldable terminal 500 from the avoidance opening.

[0145] When disassembling the shaft cover 20, the disassembly tool can be directly inserted into the first disassembly opening 261 from the avoidance opening, without disassembling other components of the foldable terminal 500, thereby further facilitating the disassembly of the shaft cover 20 and further reducing the maintenance cost.

[0146] As Figure 9 shown, the structure of the second disassembly opening 262 is the same as that of the first disassembly opening 261. The second disassembly opening 262 is provided at the top of the second end plate 215 and penetrates the top surface 101 of the second end plate 215, and the second disassembly opening 262 penetrates the inner surface and the outer surface of the second end plate 215. When the shaft cover assembly 100 is applied to the foldable terminal 500, the second disassembly opening 262 exposes the outside of the foldable terminal 500.

[0147] When disassembling the shaft cover 20, the disassembly tool can be inserted into the first disassembly opening 261, and then a force is applied to the shaft cover 20 in a direction away from the base 10, so that the first clamping body 23 near the first end plate 214 is unlocked from the first clamping groove 12, and the second clamping body 24 near the first end plate 214 is unlocked from the second clamping groove 13. Then, the disassembly tool is inserted into the second disassembly opening 262, and then a force is applied to the shaft cover 20 in a direction away from the base 10, so that the first clamping body 23 near the second end plate 215 is unlocked from the first clamping groove 12, and the second clamping body 24 near the second end plate 215 is unlocked from the second clamping groove 13, so that the shaft cover 20 is separated from the base 10 and the disassembly of the shaft cover 20 is achieved.

[0148] In this embodiment, by providing disassembly openings 26 at opposite ends in the length direction of the shaft cover 20, maintenance personnel can disassemble the shaft cover 20 from opposite ends in the length direction of the shaft cover 20 respectively, thereby reducing the disassembly difficulty of the shaft cover 20 and reducing the maintenance cost.

[0149] Please refer to Figure 13 , Figure 13 is Figure 5 a partial cross-sectional structural schematic diagram of the shaft cover assembly 100 shown along the D-D direction.

[0150] The shaft cover assembly 100 further includes a limiting member 30. In this embodiment, there are two limiting members 30. The two limiting members 30 are respectively a first limiting member 31 and a second limiting member 32. The first limiting member 31 is disposed between the first end face 105 and the first end plate 214. The second limiting member 32 is disposed between the second end plate 215 and the second end face 106. In this embodiment, the opposite two faces of the first limiting member 31 are respectively in contact with the surface of the first end plate 214 facing the base 10 and the first end face 105, and the opposite two faces of the second limiting member 32 are respectively in contact with the surface of the second end plate 215 facing the base 10 and the second end face 106. The first limiting member 31 and the second limiting member 32 can limit the shaft cover 20 in the Y direction, that is, the length direction of the shaft cover assembly 100, so as to avoid the shaft cover 20 from shaking in the Y direction, and further improve the connection stability between the shaft cover 20 and the base 10.

[0151] In other embodiments, the limiting member 30 can also be one. When the limiting member 30 is one, the limiting member 30 can be disposed between the first end face 105 and the first end plate 214, or can be disposed between the second end face 106 and the second end plate 215.

[0152] In this embodiment, both the first limiting member 31 and the second limiting member 32 are rubber pads. The first limiting member 31 abuts against the surface of the first end plate 214 facing the base 10 and the first end face 105, and the second limiting member 32 abuts against the surface of the second end plate 215 facing the base 10 and the second end face 106. In other embodiments, the first limiting member 31 and the second limiting member 32 can also be foam, adhesive or glue, etc. The structure and material of the first limiting member 31 and the second limiting member 32 are not specifically limited here.

[0153] When the first limiting member 31 is glue or adhesive, the first limiting member 31 is bonded between the surface of the first end plate 214 facing the base 10 and the first end face 105, which can improve the stability between the shaft cover 20 and the base 10. When the second limiting member 32 is glue or adhesive, the second limiting member 32 is bonded between the surface of the second end plate 215 facing the base 10 and the second end face 106, which can further improve the stability between the shaft cover 20 and the base 10.

[0154] In one implementation manner, the first limiting member 31 and the second limiting member 32 can also be of different materials. For example, the first limiting member 31 is a rubber pad and the second limiting member 32 is glue.

[0155] The above are only some embodiments and implementation manners of the present application. The protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
