Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a terminal device. Background Art

[0002] With the development of communication technology, foldable display devices have gradually been favored by many users. They can not only bring better visual impact to users, but also meet users' needs for portability.

[0003] Currently, display devices equipped with foldable displays typically include a hinge component and two housings connected by the hinge component. The hinge component enables the two housings to rotate relative to each other, thereby driving the foldable display in the terminal device to switch between a folded state and an unfolded state.

[0004] However, when the terminal device is in a folded state, the outermost side of the hinge component is subjected to an impact force, and the hinge component is very likely to be displaced toward the direction of the folding display screen. The displaced hinge component will squeeze the bending area in the folding display screen, causing the folding display screen to be easily damaged, thereby resulting in low reliability of the terminal device.

[0042] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0043] The embodiment of the present application provides a terminal device, which can be a foldable mobile phone or a foldable tablet computer. Figure 1 , Figure 1This is a partial structural diagram of a terminal device provided by an embodiment of the present application. The terminal device 000 may include: a hinge component 100 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 used as an example for schematic description.

[0044] Please refer to Figure 2 and Figure 3 , Figure 2 This is a structural diagram of a support base provided in an embodiment of the present application. Figure 3 yes Figure 1 The terminal device is shown in a schematic diagram of its structure in an unfolded state. The hinge component 100 in the terminal device 000 may include a support base 101 and at least two stoppers 102. The support base 101 may have two connecting shafts 101a, which may correspond to at least two stoppers 102, and each stopper 102 may be sleeved onto a corresponding connecting shaft 101a.

[0045] Here, 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 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.

[0046] The two housings 200 in the terminal device 000 can be located on either side of the hinge member 100, and both housings 200 can be rotatably connected to the support base 101 in the hinge member 100. Here, under the action of the hinge member 100, the two housings 200 can generate relative rotation, thereby driving the terminal device 000 to switch between the folded state and the unfolded state. Each housing 200 can have at least one limiting groove U, and the at least two limiting grooves U can correspond one-to-one with the at least two limiting members 102.

[0047] In the present application, the terminal device may further include: a foldable display screen 001, which may include two flat areas 0011 and a bending area 0012 located between the two flat areas 0011. The two flat 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 configured in conjunction with the hinge component 100.

[0048] Here, when the terminal device 000 is in the folded state, the end of each limiting member 102 facing away from the connecting shaft 101a can be located in the corresponding limiting groove U, and the limiting member 102 can abut against the housing 200 through the portion extending into the limiting groove U. In this way, even if the outermost side of the hinge member 100 is subjected to an impact force, the displacement of the hinge member 100 can be limited by the abutment between the limiting member 102 and the housing 200 provided with the limiting groove U, thereby ensuring that the hinge member 100 is not easily displaced toward the folding display screen 001 in the terminal device 000, thereby ensuring that the hinge member 100 does not squeeze the bending area 0012 of the folding display screen 001 in the terminal device 000, making the folding display screen 001 in the terminal device 000 less likely to be damaged, thereby improving the reliability of the terminal device 000.

[0049] In addition, if Figure 3 As shown, when the terminal device 000 is in the unfolded state, the end of each limiting member 102 facing away from the connecting shaft 101a can be located outside the corresponding limiting groove U. In this way, it can be ensured that the rotation of the housing 200 of the terminal device 000 relative to the rotating shaft component 100 will not be interfered with by the limiting member 102 during the switching process between the folded state and the unfolded state.

[0050] In summary, an embodiment of the present application provides a terminal device, comprising: a hinge component and two shells. After the terminal device is in a folded state, the end of each limiting member facing away from the connecting shaft can be located in a corresponding limiting groove, and the limiting member can abut against the shell through the portion extending into the limiting groove. In this way, even if the outermost side of the hinge component is subjected to an impact force, the displacement of the hinge component can be limited by the abutment between the limiting member and the shell provided with the limiting groove, so as to ensure that the hinge component is not easily displaced in the direction of the folding display screen in the terminal device, thereby ensuring that the hinge component will not squeeze the bending area of ​​the folding display screen in the terminal device, making the folding display screen in the terminal device less likely to be damaged, thereby improving the reliability of the terminal device.

[0051] In the embodiment of the present application, the position-limiting member 102 in the rotating shaft component 100 and the corresponding connecting shaft 101a can be fixedly connected, or the position-limiting member 102 in the rotating shaft component 100 and the corresponding connecting shaft 101a can be rotatably connected. To this end, the embodiment of the present application will be schematically described using the following two optional implementation methods as examples.

[0052] In a first optional implementation, when each limiting member 102 is fixedly connected to the corresponding connecting shaft 101a, each connecting shaft 101a can rotate relative to the support base 101. When the terminal device 000 switches from the unfolded state to the folded state, the connecting shaft 101a can drive the limiting member 102 to rotate about a first rotation direction, so that the end of the limiting member 102 facing away from the connecting shaft 101a can be located in the corresponding limiting groove U. Here, the first rotation direction can be one of a clockwise direction and a counterclockwise direction.

[0053] 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 connecting shaft 101a rotates in the clockwise direction, the connecting shaft 101a rotating in the clockwise direction can drive the corresponding limiting member 102 to rotate in the clockwise direction. In this case, after the end of the limiting member 102 facing away from the connecting shaft 101a extends into the corresponding limiting groove U, the limiting member 102 can limit the housing 200 and the support base 101 in the rotating shaft component 100 to ensure that when the outermost side of the rotating shaft component 100 is subjected to an impact force, there will be no relative displacement between the housing 200 and the support base 101, thereby ensuring that the support base 101 will not squeeze the bending area 0012 in the folding display screen 001. It should be noted that during the process of the terminal device 000 switching between the unfolded state and the folded state, the two connecting shafts 101a provided on the support base 100 can rotate in opposite directions. That is, when one connecting shaft 101 a rotates clockwise, the other connecting shaft 101 a needs to rotate counterclockwise.

[0054] When the terminal device 000 switches from the folded state to the unfolded state, the connecting shaft 101a can drive the limiting member 102 to rotate in a second rotation direction opposite to the first rotation direction, so that the end of the limiting member 102 facing away from the connecting shaft 101a can be moved out of the corresponding limiting groove U. Here, the second rotation direction can be the other of the clockwise direction and the counterclockwise direction.

[0055] For example, when the terminal device 000 switches from the folded state to the unfolded state, under the action of an external force, the connecting shaft 101a rotates counterclockwise, and the counterclockwise rotating connecting shaft 101a can drive the corresponding limiting member 102 to rotate counterclockwise. In this case, after the end of the limiting member 102 facing away from the connecting shaft 101a moves out of the corresponding limiting slot U, it can be ensured that the rotation of the housing 200 in the terminal device 000 relative to the rotating shaft component 100 will not be interfered with by the limiting member 102 during the process of switching between the folded state and the unfolded state.

[0056] In the examples of this application, please refer to Figure 4 , Figure 4This is a partial structural diagram of another terminal device provided in an embodiment of the present application. The position-limiting member 102 may include a connecting portion 102a and a position-limiting protrusion 102b. The connecting portion 102a may be sleeved onto and fixedly connected to the connecting shaft 101a, while the position-limiting protrusion 102b may be fixedly connected to the connecting portion 102a.

[0057] When the terminal device is in the folded state, the end of the limiting protrusion 102b in the limiting member 102, which is away from the connecting portion 102a, can be located within the limiting groove U. In this way, the limiting member 102 can be in contact with the housing 200 via the limiting protrusion 102b. Therefore, even if the outermost side of the hinge member 100 is subjected to an impact force, the displacement of the hinge member 100 can be limited by the abutment between the limiting member 102 and the housing 200 provided with the limiting groove U, thereby ensuring that the hinge member 100 is not easily displaced toward the folding display screen 001 in the terminal device 000, thereby ensuring that the hinge member 100 does not squeeze the bending area 0012 of the folding display screen 001 in the terminal device 000.

[0058] In this application, please refer to Figure 5 , Figure 5 yes Figure 4 The structure of the terminal device in the unfolded state is shown. The hinge component 100 may further include an end cap 103 fixedly connected to the support base 101, and an accommodating space may be defined between the end cap 103 and the support base 101. Here, at least a portion of the connecting shaft 101a and the limiting member 102 in the support base 101 may be located within the accommodating space, and the end of the limiting protrusion 102b facing away from the connecting portion 102a may extend outside the accommodating space.

[0059] When the terminal device 000 is in the unfolded state, the limiting protrusion 102b of the limiting member 102 can abut against the side of the end cover 103 facing the support base 101. In this way, when the terminal device 000 is in the unfolded state, the limiting member 102 can abut against the end cover 103 through the limiting protrusion 102b to ensure that the limiting member 102 does not continue to rotate relative to the support base 101.

[0060] For the second optional implementation, please refer to Figure 6 and Figure 7 , Figure 6 This is a partial structural diagram of another terminal device provided in an embodiment of the present application. Figure 7 yes Figure 6The terminal device 000 is shown as a schematic diagram of the structure of the terminal device in the unfolded state. When each limiting member 102 is rotatably connected to the corresponding connecting shaft 101a, each limiting member 102 can be fixed to the support base 101. After detecting that the terminal device 000 is in the folded state, the terminal device 000 can control the end of the limiting member 102 away from the connecting shaft 101a to move into the corresponding limiting groove U.

[0061] For example, when the terminal device 000 switches from the unfolded state to the folded state, after detecting that the terminal device 000 is in the folded state, the terminal device 000 can control the limiting member 102 to move the end of the limiting member 102 away from the connecting shaft 101a into the corresponding limiting groove U. In this case, after the end of the limiting member 102 away from the connecting shaft 101a extends into the corresponding limiting groove U, the limiting member 102 can limit the housing 200 and the support base 101 in the rotating shaft component 100, so as to ensure that after the outermost side of the rotating shaft component 100 is impacted, no relative displacement occurs between the housing 200 and the support base 101, thereby ensuring that the support base 101 does not squeeze the bending area 0012 in the folding display screen 001.

[0062] After detecting that the terminal device 000 has a tendency to unfold, the terminal device 000 can control the end of the limiting member 102 away from the connecting shaft 101a to move out of the corresponding limiting groove U. For example, when the terminal device 000 switches from the folded state to the unfolded state, after detecting that the terminal device 000 has a tendency to unfold, the terminal device 000 can control the limiting member 102 to ensure that the end of the limiting member 102 away from the connecting shaft 101a can move out of the corresponding limiting groove U. In this case, after the end of the limiting member 102 away from the connecting shaft 101a moves out of the corresponding limiting groove U, it can be ensured that during the switching process between the folded state and the unfolded state, the rotation of the housing 200 in the terminal device 000 relative to the rotating shaft component 100 will not be interfered by the limiting member 102.

[0063] In the embodiments of this application, Figure 6As shown, the limiting member 102 may include: a connecting portion 102a and a limiting protrusion 102b, and the connecting portion 102a may be sleeved on the connecting shaft 101a and rotatably connected to the connecting shaft 101a. Here, the connecting portion 102a may be fixedly connected to the support base 101, and the limiting protrusion 102b may be slidably connected to the connecting portion 102a. For example, after detecting that the terminal device 000 is in a folded state, the terminal device 000 may control the limiting member 102 so that the limiting protrusion 102b in the limiting member 102 can slide relative to the connecting portion 102a, so that the limiting protrusion 102b can move into the corresponding limiting groove U. For another example, after detecting that the terminal device 000 has a tendency to unfold, the terminal device 000 can control the limiting member 102 so that the limiting protrusion 102b in the limiting member 102 can slide relative to the connecting portion 102a, so that the limiting protrusion 102b can be moved out of the corresponding limiting groove U.

[0064] When the terminal device 000 is in the folded state, the end of the limiting protrusion 102b facing away from the connecting portion 102a can be located within the limiting groove U. In this way, the limiting member 102 can be ensured to abut against the housing 200 via the end of the limiting protrusion 102b facing away from the connecting portion 102a. Therefore, even if the outermost side of the hinge member 100 is subjected to an impact force, the displacement of the hinge member 100 can be limited by the abutment between the limiting member 102 and the housing 200 provided with the limiting groove U, thereby ensuring that the hinge member 100 is not easily displaced toward the folding display screen 001 in the terminal device 000, thereby ensuring that the hinge member 100 does not squeeze the bending area 0012 of the folding display screen 001 in the terminal device 000.

[0065] In the examples of this application, please refer to Figure 8 and Figure 9 , Figure 8 : is an exploded schematic diagram of a limiter provided in an embodiment of the present application, Figure 9 Schematic diagram of the structure of a first magnet and a second magnet provided in an embodiment of the present application. The connecting portion 102a of the position-limiting member 102 may include a slot 1021 and an opening communicating with the slot 1021. Here, the position-limiting protrusion 102b may include a first magnet 1022. A portion of the first magnet 1022 may be located within the slot 1021, while another portion may extend out of the slot 1021 through the opening.

[0066] The limiting member 102 in the terminal device 000 may further include: a second magnet 1023 fixed in the sliding groove 1021 , and the first magnet 1022 may be closer to the opening than the second magnet 1023 .

[0067] The terminal device 000 may control the magnetism of at least one of the first magnet 1022 and the second magnet 1023 so that the first magnet 1022 and the second magnet 1023 repel each other, or so that the first magnet 1022 and the second magnet 1023 attract each other.

[0068] In this application, please refer to Figure 10 , Figure 10 is a schematic diagram of the cross-sectional structure of a terminal device provided in an embodiment of the present application. For example, after detecting that the terminal device 000 is in a folded state, the terminal device 000 can control the magnetic properties of at least one of the first magnet 1022 and the second magnet 1023 so that the first magnet 1022 and the second magnet 1023 repel each other. In this case, the end of the limiting protrusion 102b facing away from the connecting portion 102a can move into the corresponding limiting groove U under the action of the repulsive force. In this way, after the limiting protrusion 102b extends into the corresponding limiting groove U, the limiting protrusion 102b can limit the housing 200 and the support base 101 in the hinge component 100 to ensure that after the outermost side of the hinge component 100 is impacted, no relative displacement occurs between the housing 200 and the support base 101, thereby ensuring that the support base 101 does not squeeze the bending area 0012 in the folding display screen 001.

[0069] For example, after detecting that the terminal device 000 has a tendency to unfold, the terminal device 000 can control the magnetism of at least one of the first magnet 1022 and the second magnet 1023 so that the first magnet 1022 and the second magnet 1023 attract each other. In this case, the end of the limiting protrusion 102b facing away from the connecting portion 102a can be moved out of the corresponding limiting groove U under the action of the attraction. In this way, after the end of the limiting protrusion 102b facing away from the connecting portion 102a is moved out of the corresponding limiting groove U, it can be ensured that during the process of switching between the folded state and the unfolded state, the rotation of the housing 200 in the terminal device 000 relative to the hinge component 100 will not be interfered with by the limiting member 102.

[0070] In the present application, at least one of the first magnet 1022 and the second magnet 1023 may be an electromagnet. That is, the first magnet 1022 may be an electromagnet, or the second magnet 1023 may be an electromagnet, or both the first magnet 1022 and the second magnet 1023 may be electromagnets.

[0071] It should be noted that, when one of the first magnet 1022 and the second magnet 1023 is an electromagnet, the other of the first magnet 1022 and the second magnet 1023 may be a permanent magnet, which is not limited in this embodiment of the present application.

[0072] In the embodiment of the present application, the electromagnet may include an iron core and a coil. The terminal device 000 may control the direction of the current applied to the coil in the electromagnet to cause the first magnet 1022 and the second magnet 1023 to repel each other, or to cause the first magnet 1022 and the second magnet 1023 to attract each other.

[0073] In this application, please refer to Figure 7 The hinge assembly 100 may further include two flip assemblies 104. The support base 101 in the hinge assembly 100 may extend along a first direction A1. When the terminal device 000 is in the unfolded state, the two flip assemblies 104 may be arranged on opposite sides of the support base 101 in a second direction A2. The first direction A1 may intersect with the second direction A2. For example, the first direction A1 may be perpendicular to the second direction A2.

[0074] The two flip assemblies 104 can be rotatably connected to the support base 101 via two connecting shafts 101a, and the two housings 200 can be movably connected to the two flip assemblies 104. When the terminal device 000 switches between the unfolded state and the folded state, under the action of external force, the at least two flip assemblies 104 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 housings 200 to rotate relative to the support base 101 in the rotating shaft component 100 or rotate towards each other.

[0075] In summary, an embodiment of the present application provides a terminal device, comprising: a hinge component and two shells. After the terminal device is in a folded state, the end of each limiting member facing away from the connecting shaft can be located in a corresponding limiting groove, and the limiting member can abut against the shell through the portion extending into the limiting groove. In this way, even if the outermost side of the hinge component is subjected to an impact force, the displacement of the hinge component can be limited by the abutment between the limiting member and the shell provided with the limiting groove, so as to ensure that the hinge component is not easily displaced in the direction of the folding display screen in the terminal device, thereby ensuring that the hinge component will not squeeze the bending area of ​​the folding display screen in the terminal device, making the folding display screen in the terminal device less likely to be damaged, thereby improving the reliability of the terminal device.
