[0043] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0044] The present application embodiment provides a terminal device, which may be a foldable mobile phone or a foldable tablet computer. Figure 1 , Figure 1 000 is a partial structural diagram of a terminal device provided in an embodiment of the present application. The terminal device 000 may include: a rotating shaft component 100, a stopper 300 and two housings 200. The terminal device 000 may have an unfolded state and a folded state. It should be noted that: Figure 1 The structure of the terminal device 000 in a folded state is taken as an example for schematic description.

[0045] The two shells 200 in the terminal device 000 can be located on both sides of the rotating shaft component 100, and the two shells 200 can be movably connected to the rotating shaft component 100. Here, under the action of the rotating shaft component 100, the two shells 200 can generate relative rotation, thereby driving the terminal device 000 to switch between the folded state and the unfolded state. Among them, at least one shell 200 of the two shells 200 can have a limiting groove U. For example, any one shell 200 of the two shells 200 can have a limiting groove U, or the two shells 200 can both have a limiting groove U. This embodiment of the application is not limited to this.

[0046] In the present application, the terminal device may further include: a foldable display screen 001, which may include two plane areas 0011 and a bending area 0012 located between the two plane areas 0011. The two plane areas 0011 in the foldable display screen 001 may be fixedly connected to the two housings 200 respectively, and the bending area 0012 in the foldable display screen 001 may be arranged in cooperation with the hinge component 100.

[0047] The limiting member 300 in the terminal device 000 can be slidably connected to the rotating shaft component 100 , and the limiting member 300 can cooperate with the limiting groove U on the shell 200 .

[0048] Here, when the terminal device 000 switches from the unfolded state to the folded state, the hinge component 100 can drive the limiting member 300 to move in the direction toward the limiting groove U, so that a part of the limiting member 300 can be located in the limiting groove U. Figure 1As shown, after the terminal device 000 is in the folded state, a part of the stopper 300 can be located in the stopper slot U on the housing 200, and the stopper 300 can abut against the housing 200 through the part extending into the stopper slot U. Since the stopper 300 and the shaft component 100 are slidably connected, even if the outermost side of the shaft component 100 is subjected to an impact force, the displacement of the shaft component 100 can be limited by the abutment between the stopper 300 and the housing 200 provided with the stopper slot U, so as to ensure that the shaft component 100 is not easily displaced toward the direction of the folding display screen 001 in the terminal device 000, thereby ensuring that the shaft component 100 will not squeeze the bending area 0012 of the folding display screen 001 in the terminal device 000, so that the folding display screen 001 in the terminal device 000 is not easily damaged, thereby improving the reliability of the terminal device 000.

[0049] In addition, when the terminal device 000 is switched from the folded state to the unfolded state, the hinge component 100 can also drive the limiting member 300 to move in a direction away from the limiting groove U, so that the limiting member 300 can be completely distributed outside the limiting groove U. Figure 2 As shown, Figure 2 yes Figure 1 The structural schematic diagram of the terminal device 000 in the unfolded state shows that after the terminal device 000 is in the unfolded state, the limiting member 300 can be completely located outside the limiting groove U on the shell 200, thereby ensuring that during the switching process of the terminal device 000 between the folded state and the unfolded state, the rotation of the shell 200 in the terminal device 000 relative to the hinge component 100 will not be interfered by the limiting member 300.

[0050] In summary, a terminal device provided by an embodiment of the present application includes: a rotating shaft component, a limiting component and two shells. In the process of switching the terminal device from an unfolded state to a folded state, the rotating shaft component can drive the limiting component to move in the direction toward the limiting groove, so that a part of the limiting component can be located in the limiting groove. In this way, after the terminal device is in the folded state, a part of the limiting component can be located in the limiting groove on the shell, and the limiting component can abut against the shell through the part extending into the limiting groove. Since the limiting component and the rotating shaft component are slidably connected, even if the outermost side of the rotating shaft component is subjected to an impact force, the displacement of the rotating shaft component can be limited by the abutment between the limiting component and the shell provided with the limiting groove, so as to ensure that the rotating shaft component is not easy to displace in the direction of the folding display screen in the terminal device, thereby ensuring that the rotating shaft component will not squeeze the bending area of ​​the folding display screen in the terminal device, so that the folding display screen in the terminal device is not easy to be damaged, thereby improving the reliability of the terminal device.

[0051] In the examples of this application, please refer to Figure 3 , Figure 3 The structure diagram of a terminal device provided by an embodiment of the present application is shown in FIG. 1. The rotating shaft component 100 in the terminal device 000 may include: a supporting base 101 and at least two flipping components 102 rotatably connected to the supporting base 101 .

[0052] The support seat 101 in the rotating shaft component 100 can extend along the first direction X. It should be noted that the support seat 101 can be a split structure or an integrated structure. In order to facilitate processing and assembly, the support seat 101 can be set as a split structure and connected together by connecting members (for example, screws). The support seat 101 can also be set as an integrated structure, and the support seat 101 can be a strip-shaped structure extending along the first direction X. It should be noted that the above description of the support seat 101 is only an example and not a limitation. The embodiment of the present disclosure does not specifically limit the shape and connection form of the support seat 101.

[0053] At least two flip assemblies 102 in the hinge member 100 can be rotatably connected to the support base 101, and when the terminal device 000 is in the unfolded state, at least two flip assemblies 102 are relatively arranged on both sides of the support base 101 in the second direction Y. The first direction X can intersect with the second direction Y. For example, the first direction X can be perpendicular to the second direction Y.

[0054] In the present application, the two flip assemblies 102 distributed on both sides of the support base 101 can be movably connected to the two shells 200. Here, when the terminal device 000 switches between the unfolded state and the folded state, under the action of external force, at least two flip assemblies 102 distributed on both sides of the support base 101 can rotate relative to each other or rotate towards each other in different directions, thereby driving the two shells 200 to rotate relative to the support base 101 in the rotating shaft component 100 or rotate towards each other.

[0055] Among them, please refer to Figure 4 and Figure 5 , Figure 4 yes Figure 3 The cross-sectional schematic diagram of the terminal device after expansion is shown. Figure 5 yes Figure 3 In the cross-sectional schematic diagram of the terminal device after folding, the position-limiting member 300 in the terminal device 000 can be slidably connected to the support base 101 and is transmission-connected to the flip assembly 102. For example, when the terminal device 000 switches between the unfolded state and the folded state, the flip assembly 102 can rotate relative to the support base 101 under the action of an external force. During the rotation of the flip assembly 102, the flip assembly 102 can not only drive the connected housing 200 to rotate synchronously, but also drive the position-limiting member 300 to slide relative to the support base 101.

[0056] Here, in the process of switching the terminal device 000 from the unfolded state to the folded state, the flip assembly 102 can drive the limiter 300 to slide in the direction of the housing 200 provided with the limiter slot U. After a part of the limiter 300 extends into the limiter slot U, the housing 200 and the support seat 101 in the shaft component 100 can be limited by the limiter 300 to ensure that after the outermost side of the shaft component 100 is impacted, there will be no relative displacement between the housing 200 and the support seat 101, thereby ensuring that the support seat 101 will not squeeze the bending area 0012 in the folding display screen 001. In the process of switching the terminal device 000 from the folded state to the unfolded state, the flip assembly 102 can drive the limiter 300 to slide in the direction away from the limiter slot U, so that the limiter 300 can be completely moved out of the limiter slot U, thereby ensuring that the flip assembly 102 can normally drive the housing 200 to rotate.

[0057] In the embodiment of the present application, when any one of the two shells 200 of the terminal device 000 has a limit groove U, a limit member 300 that cooperates with the limit groove U needs to be set in the terminal device 000, and one of the two flip components 102 of the terminal device 000 can be movably connected to the shell 200 with the limit groove U, and the other flip component 102 can be movably connected to the other shell 200 and is transmission-connected to the limit member 300.

[0058] In the case where both housings 200 of the terminal device 000 have a limiting groove U, two limiting members 300 need to be provided in the terminal device 000, and the two limiting members 300 can respectively cooperate with the two limiting grooves U provided on the two housings 200. Here, for any one of the two flip assemblies 102 in the terminal device 000, the flip assembly 102 can be movably connected to a housing 200 with a limiting groove U, and is transmission-connected to a limiting member 300, and the limiting member 300 can cooperate with the limiting groove U provided on the other housing 200.

[0059] To this end, for a set of transmission-connected stopper 300 and flip assembly 102, the flip assembly 102 can be rotationally connected with one of the two shells 200, and the other of the two shells 200 can have a stopper slot U that matches the stopper 300. In this case, it can be ensured that after the terminal device 000 is in the folded state, the distance between the position of the stopper 300 extending into the stopper slot U and the position of the stopper 300 transmission-connected with the flip assembly 102 is large, thereby ensuring that the stopper 300 can more stably limit the shell 200 and the support seat 101 in the rotating shaft component 100.

[0060] In the examples of this application, please refer to Figure 6 and Figure 7 , Figure 6 is a partial schematic diagram of a rotating shaft component provided in an embodiment of the present application, Figure 7 It is a schematic diagram of the coordination of a support seat, a stopper and a flip assembly provided in an embodiment of the present application. The stopper 300 in the terminal device 000 can be in the shape of an elongated strip, and the support seat 101 in the rotating shaft component 100 can have a slide groove 101a that is slidably connected to the stopper 300. In this way, when the terminal device 000 switches between the unfolded state and the folded state, the stopper 300 can slide more smoothly relative to the support seat 101 through the slide groove 101a. Among them, the extension direction of the stopper 300 in the terminal device 000 and the extension direction of the slide groove 101a in the support seat 101 can be parallel to the second direction Y. In this case, under the driving action of the rotating shaft component 100, the stopper 300 in the terminal device 000 can only slide along the second direction Y in the slide groove 101a.

[0061] In this application, if Figure 6 and Figure 7 As shown, the first end of the stopper 300 in the terminal device 000 can be connected to the flip assembly 102 in the shaft component 100 in a transmission manner. After the terminal device 000 is in the folded state, the stopper slot U in the housing 200 can be connected to the slide slot 101a in the support seat 101, so that the second end of the stopper 300 can extend into the stopper slot U. In this way, after the terminal device 000 is in the folded state, the housing 200 and the support seat 101 in the shaft component 100 can be stably connected by the stopper 300 in the terminal device 000, so as to ensure that the shaft component 100 is not easily displaced relative to the housing 200. For this reason, even after the outermost side of the shaft component 100 is subjected to an impact force, there will be no relative displacement between the housing 200 and the support seat 101, thereby ensuring that the support seat 101 will not squeeze the bending area 0012 in the folding display screen 001.

[0062] In the examples of this application, please refer to Figure 7 The flip assembly 102 in the rotating shaft component 100 may include: a driving rod 102a.

[0063] The first end of the driving rod 102a in the flip assembly 102 can be rotatably connected to the support base 101 in the rotating shaft component 100. For example, when the terminal device 000 switches between the unfolded state and the folded state, the first end of the driving rod 102a in the flip assembly 102 can rotate relative to the support base 101 under the action of external force.

[0064] The second end of the driving rod 102a in the flip assembly 102 can be slidably connected to the housing 200. For example, when the terminal device 000 switches from the unfolded state to the folded state, under the action of external force, the driving rod 102a slidably connected to the housing 200 in the terminal device 000 can rotate counterclockwise. During the rotation process, the folding display screen 001 usually has a tendency to stretch, and the second end of the driving rod 102a slidably connected to the housing 200 in the terminal device 000 can have the freedom to move away from the support base 101, so that the housing 200 can cooperate with the movement trend of the folding display screen 001, ensuring that the housing 200 will not pull the folding display screen 001.

[0065] In this application, if Figure 7 As shown, the first end of the driving rod 102a in the flip assembly 102 may have a first transmission member 1021, and the first end of the limiting member 300 in the terminal device 000 may have a second transmission member 300a that is transmission-connected to the first transmission member 1021. Here, during the rotation of the driving rod 102a, the driving rod 102a can drive the limiting member 300 to slide relative to the support base 101 through the cooperation of the first transmission member 1021 and the second transmission member 300a.

[0066] For example, the first transmission member 1021 in the driving rod 102a may include: a plurality of first external teeth 1021a arranged in an array around the rotation axis of the driving rod 102a, and the second transmission member 300a in the limiting member 300 may include: a plurality of second external teeth 3001 arranged in an array along the second direction Y, and at least part of the first external teeth 1021a may be meshed with at least part of the second external teeth 3001. For example, when the terminal device 000 switches from the unfolded state to the folded state, under the action of an external force, when the driving rod 102a rotates counterclockwise, the driving rod 102a also drives the first external teeth 1021a to rotate counterclockwise, and then the first external teeth 1021a drives the second external teeth 3001 on the limiting member 300 to move in the second direction Y. In this case, the limiting member 300 can slide relative to the support seat 101 through the meshing action of the first external teeth 1021a and the second external teeth 3001. That is, the cooperation between the first transmission member 1021 and the second transmission member 300a is similar to the transmission cooperation of a gear rack. It should be noted that the number of the first external teeth 1021a on the driving rod 102a and the number of the plurality of second external teeth 3001 on the limiting member 300 can be designed according to the rotation angle of the terminal device 000, and no specific limitation is made here.

[0067] In the examples of this application, please refer to Figure 8 , Figure 8 yes Figure 3 Another cross-sectional view of the terminal device after folding is shown. The hinge component 100 in the terminal device 000 may also include: an end cap 103 fixedly connected to the support base 101 .

[0068] like Figure 8 As shown, the slide groove 101a of the support seat 101 in the rotating shaft component 100 can be located on the side of the support seat 101 facing the end cover 103, and the side of the slide groove 101a in the support seat 101 facing the end cover 103 can have a strip opening. Among them, the side of the first end of the limiting member 300 in the terminal device 000 that is exposed from the strip opening of the slide groove 101a can have a second transmission member 300a, and the first transmission member 1021 in the driving rod 102a can be located between the support seat 101 and the end cover 103, and distributed toward the strip opening of the slide groove 101a. In this way, it can be ensured that the second transmission member 300a set at the first end of the limiting member 300 can normally engage with the first transmission member 1021 in the driving rod 102a.

[0069] In the examples of this application, please refer to Fig. 9 , Fig.10 and Fig.11 , Fig. 9 is a partial structural schematic diagram of a support base provided in an embodiment of the present application, Fig.10is a schematic diagram of the structure of a limiter provided in an embodiment of the present application, Fig.11 1 is a schematic diagram of the cooperation between a support seat and a stopper provided in an embodiment of the present application. The slide slot 101a in the support seat 101 may include: a slide slot body 1011, and two anti-slip slide slots 1012 located on both sides of the slide slot body 1011 in the first direction X and connected to the slide slot body 1011, wherein the slide slot body 1011 may have a strip-shaped opening.

[0070] The stopper 300 in the terminal device 000 may include: a sliding portion 301 located in the slide groove body 1011 in the slide groove 101a, and two anti-dropping protrusions 302 respectively fixedly connected to both sides of the sliding portion 301 in the stopper 300 in the first direction X. Here, the first end of the sliding portion 301 in the stopper 300 may have a second transmission member 300a. That is, through the cooperation of the second transmission member 300a at the first end of the sliding portion 301 in the stopper 300 and the first transmission member 1021 at the first end of the driving rod 102a in the flip assembly 102, the sliding portion 301 in the stopper 300 can be connected in transmission with the driving rod 102a in the flip assembly 102.

[0071] The two anti-dropout protrusions 302 can be respectively located in the two anti-dropout slide grooves 1012 in the slide groove 101a. In this case, when the terminal device 000 switches between the unfolded state and the folded state, the two anti-dropout protrusions 302 can respectively slide smoothly in the two anti-dropout slide grooves 1012 in the slide groove 101a relative to the support seat 101, thereby ensuring that the limiter 300 is not easy to fall off from the slide groove 101a, thereby improving the reliability of the terminal device 000.

[0072] In this application, if Figure 8 and Fig.10 As shown, the second end of the sliding portion 301 in the limiting member 300 may have a limiting protrusion 3011 protruding from the anti-slip protrusion 302 in the second direction Y. After the terminal device 000 is in the folded state, the limiting protrusion 3011 in the limiting member 300 may be located in the limiting groove U. In this way, it can be ensured that the limiting member 300 can abut against the housing 200 through the limiting protrusion 3011. Therefore, even if the outermost side of the rotating shaft component 100 is subjected to an impact force, the displacement of the rotating shaft component 100 can be limited by the abutment between the limiting member 300 and the housing 200 provided with the limiting groove U, so as to ensure that the rotating shaft component 100 is not easy to be displaced toward the direction of the folding display screen 001 in the terminal device 000, thereby ensuring that the rotating shaft component 100 will not squeeze the bending area 0012 of the folding display screen 001 in the terminal device 000.

[0073] In the examples of this application, please refer to Fig.12 , Fig.12 It is a schematic diagram of the structure of another limiting member provided in an embodiment of the present application. The width of the limiting protrusion 3011 in the limiting member 300 in the third direction Z can be gradually reduced along the direction from the first end to the second end of the limiting member 300. Among them, the third direction Z can intersect with the first direction X and intersect with the second direction Y. For example, the third direction Z can be perpendicular to the first direction X and perpendicular to the second direction Y. In this way, in the process of the terminal device 000 switching from the unfolded state to the folded state, it can be ensured that the width of the limiting protrusion 3011 at one end facing the limiting groove U is smaller, so that the limiting member 300 is easier to extend into the limiting groove U, and the width of the limiting protrusion 3011 is gradually changing, so it can be ensured that after the terminal device 000 is in the folded state, the limiting protrusion 3011 and the limiting groove U in the shell 200 have a better abutment effect.

[0074] In the examples of this application, please refer to Fig.13 , Fig.13 It is a schematic diagram of the structure of another terminal device provided in an embodiment of the present application. The flip assembly 102 may also include: a flip plate 102b and a swing arm 102c.

[0075] One end of the swing arm 102c in the flip assembly 102 can be rotatably connected to the support base 101, the other end of the swing arm 102c in the flip assembly 102 can be fixedly connected to the housing 200 in the terminal device 000, and the flip plate 102b in the flip assembly 102 can be rotatably connected to the driving rod 102a in the flip assembly 102. Among them, one side of the flip plate 102b in the flip assembly 102 can be used to be attached to the back of the folding display screen 001 in the terminal device 000. For example, when the terminal device 000 switches from the unfolded state to the folded state, under the action of external force, the driving rod 102a that is slidably connected to the housing 200 in the terminal device 000 can rotate counterclockwise, and at this time, the driving rod 102a will drive the swing arm 102c and the flip plate 102b to rotate counterclockwise. During the rotation process, the folding display screen 001 usually has a tendency to stretch, and the driving rod 102a connected to the housing 200 in the terminal device 000 can have the freedom to move away from the support base 101, so that the housing 200 can match the movement trend of the folding display screen 001, ensuring that the housing 200 does not pull the folding display screen 001. In this case, the hinge component 100 can be in a "water drop" shape, also known as a water drop type hinge component.

[0076] When the terminal device 000 switches from the folded state to the unfolded state, under the action of external force, the driving rod 102a fixedly connected to the shell 200 in the terminal device 000 can rotate in the clockwise direction. At this time, the driving rod 102a will drive the swing arm 102c and the flip plate 102b to rotate in the clockwise direction. During the rotation process, the folding display screen 001 usually shows a tendency to shrink, and the driving rod 102a connected to the shell 200 in the terminal device 000 can have the freedom to move close to the support base 101, so that the shell 200 can cooperate with the movement trend of the folding display screen 001, ensuring that the shell 200 will not pull the folding display screen 001. In addition, when the terminal device 000 is unfolded to the final state (i.e., the angle between the two flip plates 102b in the two flip assemblies 102 is 180 degrees), the two flip plates 102b in the two flip assemblies 102 are coplanar with one side close to the folding display screen 001, i.e., the two flip plates 102b in the two flip assemblies 102 are close to the one side of the folding display screen 001 and can form a flat support surface, thus providing good support for the folding display screen 001. It should be noted that the two flip assemblies 102 can be symmetrically arranged relative to the support base 101.

[0077] In summary, a terminal device provided by an embodiment of the present application includes: a rotating shaft component, two shells and a limiting component. In the process of switching the terminal device from an unfolded state to a folded state, the rotating shaft component can drive the limiting component to move in the direction toward the limiting groove, so that a part of the limiting component can be located in the limiting groove. In this way, after the terminal device is in the folded state, a part of the limiting component can be located in the limiting groove on the shell, and the limiting component can abut against the shell through the part extending into the limiting groove. Since the limiting component and the rotating shaft component are slidably connected, even if the outermost side of the rotating shaft component is subjected to an impact force, the displacement of the rotating shaft component can be limited by the abutment between the limiting component and the shell provided with the limiting groove, so as to ensure that the rotating shaft component is not easy to displace in the direction of the folding display screen in the terminal device, thereby ensuring that the rotating shaft component will not squeeze the bending area of ​​the folding display screen in the terminal device, so that the folding display screen in the terminal device is not easy to be damaged, thereby improving the reliability of the terminal device.
