Description

Technical Field

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

[0002] As flexible display technology matures, the display mode of terminal devices has undergone tremendous changes. Foldable flexible display mobile phones, foldable flexible display tablets, and wearable terminal devices with foldable flexible displays are an important evolutionary direction for future smart terminal devices.

[0003] In a foldable terminal device, if the holding force in the closed state is too small, the foldable terminal device cannot be closed smoothly, and if the holding force in the flattened state is too small, the foldable terminal device cannot always be kept in the flattened state. It can be seen that the holding force in the closed state and the flattened state of the foldable terminal device are key factors affecting the user's opening and closing experience. However, in current foldable terminal devices, the holding force in the closed state and the flattened state cannot be adjusted separately, which results in that when any holding force is adjusted, it will affect the opening and closing process force of the foldable terminal device, thereby affecting the opening and closing feel of the foldable terminal device.

[0004] Based on this, how to ensure that the foldable terminal device can be stably maintained in a closed state and a flattened state while ensuring a more comfortable opening and closing feel has become a difficult problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] The present application provides a terminal device, which can not only enable the terminal device to be stably maintained in a closed state and a flattened state, but also reduce the impact of the force on the opening and closing process, thereby improving the user experience.

[0006] The present application provides a terminal device, which includes a hinge mechanism, a first shell, a first magnetic component and a first sliding module. Among them, the hinge mechanism includes a main shaft and a first rotating component, the first shell is rotatably connected to the main shaft through the first rotating component, and the first magnetic component is arranged on the first shell. When the first rotating component is specifically arranged, it may include a first swing arm, the first swing arm is rotatably connected to the main shaft, and the first swing arm is slidably connected to the first shell. When the first shell rotates around the main shaft, the first swing arm slides relative to the first shell, so that the first shell drives the first swing arm to rotate around the main shaft. In addition, the first sliding module includes a first magnetic part and a second magnetic part, and the first sliding module slides relative to the first shell with the first swing arm. In this way, when the terminal device is in a flattened state, the first magnetic part is adsorbed with the first magnetic component, so that the relative sliding of the first swing arm and the first shell can be restricted, so that the first shell of the terminal device can be stably maintained in the flattened state. When the terminal device changes from a flattened state to a closed state, the first magnetic part is separated from the first magnetic component, and the second magnetic part is separated from the first magnetic component. Then, the magnetic force between the first magnetic part and the first magnetic component and the magnetic force between the second magnetic part and the first magnetic component have little effect on the folding process force of the terminal device. In addition, when the terminal device is in a closed state, the second magnetic part is adsorbed to the first magnetic component, so that the first shell of the terminal device can be stably maintained in the closed state. Therefore, the terminal device provided by the present application can reduce the influence on the opening and closing process force while enabling the first shell to be stably maintained in the closed state and the flattened state, thereby effectively improving the user experience.

[0007] In a possible implementation of the present application, the first rotating assembly further includes a first support arm, the first support arm is rotatably connected to the main shaft, and the first support arm is fixedly connected to the first housing. In addition, the axis of rotation of the first support arm and the first swing arm around the main shaft do not coincide. Thus, during the rotation of the first rotating assembly around the main shaft, the rotation of the first support arm and the first swing arm around the main shaft will produce a phase difference, so that relative sliding can occur between the first swing arm and the first housing.

[0008] Based on the design that the first swing arm and the first shell can slide relative to each other, in a possible implementation of the present application, the first sliding module can be fixedly connected to the first swing arm, so that the first sliding module can be driven to slide relative to the first shell by the first swing arm, thereby driving the first magnetic member and the second magnetic member to slide relative to the first shell. In addition, the first shell includes a first side wall, which is arranged toward the rotating shaft mechanism, the first magnetic component is arranged on the first side wall, the first side wall is provided with a first avoidance hole, part of the first sliding module passes through the first avoidance hole, and the first magnetic member and the second magnetic member can be located on both sides of the first side wall, and the first magnetic member is located on the side of the second magnetic member away from the main axis, so that the first magnetic member can be located between the first magnetic member and the second magnetic member, so that the distance between the first magnetic member and the second magnetic member and the first magnetic member can be adjusted during the sliding process of the first sliding module relative to the first shell, and then the first magnetic member can be adsorbed with the first magnetic member when the terminal device is in a flattened state; the first magnetic member and the second magnetic member are separated from the first magnetic member when the terminal device changes from a flattened state to a closed state; and the second magnetic member is adsorbed with the first magnetic member when the terminal device is in a closed state.

In this case, the first magnetic member may be arranged at the end of the first extending portion away from the first fixed portion, and the second magnetic member may be arranged at the first fixed portion.

[0010] In another possible implementation of the present application, the first sliding module is slidably connected to the first swing arm. The first housing includes a first side wall, the first side wall is arranged toward the main shaft, the first side wall is provided with a first avoidance hole, and part of the first sliding module passes through the first avoidance hole. In addition, the first magnetic assembly includes a third magnetic part and a fourth magnetic part, and the third magnetic part and the fourth magnetic part are arranged at intervals. At this time, the first magnetic part is located between the third magnetic part and the fourth magnetic part, the second magnetic part is located between the third magnetic part and the fourth magnetic part, and the first magnetic part is arranged close to the third magnetic part relative to the second magnetic part, and the second magnetic part is arranged close to the fourth magnetic part relative to the first magnetic part. When the terminal device is in a flattened state, the first magnetic part is adsorbed with the third magnetic part so that the first housing can be stably maintained in the flattened state. In the process of the terminal device from the flattened state to the closed state, the first magnetic part is separated from the third magnetic part and the fourth magnetic part, and the second magnetic part is separated from the third magnetic part and the fourth magnetic part, then the magnetic force between the first magnetic part and the first magnetic assembly and the magnetic force between the second magnetic part and the first magnetic assembly have little influence on the folding process force of the terminal device. In addition, when the terminal device is in a closed state, the second magnetic member and the fourth magnetic member are attracted to each other, so that the first shell can be stably maintained in the closed state.

[0011] In order to enable the first sliding module to slide relative to the first shell while being slidably connected to the first swing arm. In a possible implementation of the present application, the first shell is provided with a first mounting groove, and the third magnetic component and the fourth magnetic component are respectively arranged on two oppositely arranged groove walls of the first mounting groove.

The second sliding portion can be slidably connected to the first swing arm through the first avoidance hole. In this way, the second sliding portion can be driven to slide relative to the first swing arm during the sliding process of the first swing arm relative to the first shell, so that the second sliding portion drives the first sliding portion to slide relative to the first shell in the first mounting groove along the direction from the third magnetic component to the fourth magnetic component and along the direction from the fourth magnetic component to the third magnetic component.

[0012] In a possible implementation of the present application, the first swing arm may be provided with a first track groove, and the angle between the extension direction of the first track groove and the axis direction of the main shaft may include an acute angle. In addition, the second sliding part is provided with a first guide column, the first guide column is inserted into the first track groove, and the first guide column can slide along the first track groove, so that the second sliding part and the first swing arm can slide relative to each other.

[0013] The terminal device provided in the present application also includes a second shell. In addition, the hinge mechanism also includes a second rotating assembly. The first rotating assembly and the second rotating assembly can be arranged on both sides of the axis of the main shaft, and the second shell can be rotatably connected to the main shaft through the second rotating assembly. Similar to the structure of the first rotating assembly, the second rotating assembly may include a second swing arm, which is rotatably connected to the main shaft, and the second swing arm is slidably connected to the second shell. When the second shell rotates around the main shaft, the second swing arm can slide relative to the second shell, so that the second shell drives the first swing arm to rotate around the main shaft.

[0014] In a possible implementation of the present application, the second rotating assembly further includes a second support arm, the second support arm is rotatably connected to the main shaft, and the second support arm is fixedly connected to the second housing. In addition, the axes of rotation of the second support arm and the second swing arm around the main shaft do not coincide, so that during the rotation of the second rotating assembly around the main shaft, the rotation of the second support arm and the second swing arm around the main shaft will produce a phase difference, so that relative sliding can occur between the second swing arm and the first housing.

[0015] In a possible implementation of the present application, the terminal device also includes a second magnetic component and a second sliding module, the second sliding module includes a fifth magnetic component and a sixth magnetic component, and the second sliding module slides relative to the second shell with the second swing arm. When the terminal device is in a flattened state, the fifth magnetic component is adsorbed with the second magnetic component, so that the second shell can be stably maintained in the flattened state. In the process of the terminal device changing from a flattened state to a closed state, the fifth magnetic component is separated from the second magnetic component, and the sixth magnetic component is separated from the second magnetic component. Then, the magnetic force between the fifth magnetic component and the second magnetic component and the magnetic force between the second magnetic component and the second magnetic component have little effect on the folding process force of the terminal device. In addition, when the terminal device is in a closed state, the sixth magnetic component is adsorbed with the second magnetic component, so that the second shell can be stably maintained in the closed state.

[0016] Based on the design that the second swing arm and the second shell can slide relative to each other, in a possible implementation of the present application, the second sliding module can be fixedly connected to the second swing arm, so that the second sliding module can be driven to slide relative to the second shell through the second swing arm, thereby driving the fifth magnetic part and the sixth magnetic part to slide relative to the second shell. In addition, the second shell includes a second side wall, which is arranged toward the rotating shaft mechanism, and the second magnetic component is arranged on the second side wall. The second side wall is provided with a second avoidance hole, and part of the second sliding module passes through the second avoidance hole, and the fifth magnetic component and the sixth magnetic component can be located on both sides of the second side wall, and the fifth magnetic component is located on the side of the sixth magnetic component away from the main axis, so that the second magnetic component can be located between the fifth magnetic component and the sixth magnetic component, so as to adjust the distance between the fifth magnetic component and the sixth magnetic component and the second magnetic component during the sliding of the second sliding module relative to the second shell, so that the fifth magnetic component can be adsorbed with the second magnetic component when the terminal device is in a flattened state; in the process of the terminal device changing from a flattened state to a closed state, the fifth magnetic component and the sixth magnetic component are separated from the second magnetic component; and when the terminal device is in a closed state, the sixth magnetic component is adsorbed with the second magnetic component.

[0017] When the second sliding module is specifically arranged, in a possible implementation of the present application, it may include a second fixed portion and a second extending portion connected to each other, wherein the second fixed portion is fixedly connected to the second swing arm, and the second extending portion passes through the first avoidance hole. In this case, the fifth magnetic member may be arranged at the end of the second extending portion away from the second fixed portion, and the sixth magnetic member may be arranged at the second fixed portion.

[0018] In another possible implementation of the present application, the second sliding module is slidably connected to the second swing arm. The second shell includes a second side wall, the second side wall is arranged toward the main shaft, the second side wall is provided with a second avoidance hole, and part of the second sliding module passes through the second avoidance hole. In addition, the second magnetic assembly includes a seventh magnetic member and an eighth magnetic member, and the seventh magnetic member and the eighth magnetic member are arranged at intervals. At this time, the fifth magnetic member is located between the seventh magnetic member and the eighth magnetic member, the sixth magnetic member is located between the seventh magnetic member and the eighth magnetic member, and the fifth magnetic member is arranged close to the seventh magnetic member relative to the sixth magnetic member, and the sixth magnetic member is arranged close to the eighth magnetic member relative to the fifth magnetic member. When the terminal device is in a flattened state, the fifth magnetic member is adsorbed with the seventh magnetic member so that the second shell can be stably maintained in the flattened state. In the process of the terminal device from the flattened state to the closed state, the fifth magnetic member is separated from the seventh magnetic member and the eighth magnetic member, and the sixth magnetic member is separated from the seventh magnetic member and the eighth magnetic member, then the magnetic force between the fifth magnetic member and the second magnetic assembly and the magnetic force between the sixth magnetic member and the second magnetic assembly have little influence on the folding process force of the terminal device. In addition, when the terminal device is in a closed state, the sixth magnetic member and the eighth magnetic member are attracted to each other, so that the second shell can be stably maintained in the closed state.

[0019] In order to enable the second sliding module to slide relative to the second shell while being slidably connected to the second swing arm. In a possible implementation of the present application, the second shell is provided with a second mounting groove, and the seventh magnetic component and the eighth magnetic component are respectively arranged on two oppositely arranged groove walls of the second mounting groove. The second sliding module includes a third sliding part and a fourth sliding part connected to each other, the third sliding part can be installed in the second mounting groove, and the fifth magnetic component and the sixth magnetic component are respectively arranged on two oppositely arranged ends of the third sliding part. The fourth sliding part can be slidably connected to the second swing arm through the second avoidance hole. In this way, the fourth sliding part can be driven to slide relative to the second swing arm during the sliding process of the second swing arm relative to the second shell, so that the fourth sliding part drives the third sliding part to slide relative to the second shell in the second mounting groove along the direction from the seventh magnetic component to the eighth magnetic component and along the direction from the eighth magnetic component to the seventh magnetic component.

[0020] In a possible implementation of the present application, the second swing arm may be provided with a second track groove, and the angle between the extension direction of the second track groove and the axis direction of the main shaft may include an acute angle. In addition, the fourth sliding part is provided with a second guide column, the second guide column is inserted into the second track groove, and the second guide column can slide along the second track groove, so that the fourth sliding part and the second swing arm can slide relative to each other.

[0021] In the present application, the holding force of the second shell when the terminal device is in the flattened state and the closed state can be provided by the magnetic force of the second magnetic component and the magnetic component of the second sliding module mentioned above, and can also be provided by other possible ways. In a possible implementation of the present application, the terminal device can also include a first damping component, which includes a roller, a slider and a spring, the roller is rotatably connected to the slider, and the spring is located on the side of the slider away from the roller. The second swing arm is provided with a slide groove, and the first damping component is installed in the slide groove. In addition, the main shaft is provided with a cam member, and the cam member includes a cam surface facing the damping component. Then the spring can press the roller toward the cam member so that the roller abuts against the cam surface. Then, in the process of the second shell rotating around the main shaft, the second swing arm can be driven to rotate around the main shaft, so that the second swing arm drives the first damping component to rotate around the main shaft, so that the first damping component rotates around the cam member. Since the roller of the first damping assembly is always in contact with the cam surface of the cam member, the first damping assembly can slide relative to the second swing arm during the rotation of the first damping assembly around the cam member, thereby changing the compression amount of the spring. The elastic force generated by the compression amount of the spring can be converted into a damping force that hinders the second swing arm from rotating around the main axis. The damping force can be further transmitted to the second shell to form a retaining force that stably maintains the second shell in a flattened state and a closed state.

[0022] In a possible implementation of the present application, the terminal device also includes a second damping assembly, and the second damping assembly includes a first gear connecting rod, a second gear connecting rod, a conjoined cam and an elastic assembly. Among them, the first gear connecting rod is rotationally connected to the main shaft, and the first gear connecting rod is slidably connected to the first housing. In addition, the second gear connecting rod is rotationally connected to the main shaft, and the second gear connecting rod is slidably connected to the first housing. In the present application, the first gear connecting rod includes a first gear, the second gear connecting rod includes a second gear, the conjoined cam is located between the first gear and the elastic assembly, and the conjoined cam is located between the second gear and the elastic assembly. The conjoined cam has a third cam surface at the end facing the first gear, and the conjoined cam has a fourth cam surface at the end facing the second gear. Then, under the elastic force of the elastic assembly, the first cam surface abuts against the third cam surface, and the second cam surface abuts against the fourth cam surface. The rotation of the first shell and the second shell around the main axis can drive the first gear link and the second gear link to rotate around the main axis. During the rotation process, a damping force that hinders the first gear link from rotating around the main axis can be generated between the first cam surface and the third cam surface, and a damping force that hinders the second gear link from rotating around the main axis can be generated between the second cam surface and the fourth cam surface. Because the first link of the first gear link is slidingly connected to the first shell, and the second link of the second gear link is slidingly connected to the second shell, the damping force received by the first gear link can be transmitted to the first shell, and the damping force received by the second gear link can be transmitted to the second shell. In this way, when the user unfolds or closes the terminal device, the user will have a more obvious sense of frustration, which is beneficial to improving the user experience.

[0023] In a possible implementation of the present application, the second damping assembly further includes an even number of intermediate gears, and the first gear and the second gear are connected by an even number of intermediate gears. In addition, a fifth cam surface is provided at the end of each intermediate gear facing the conjoined cam, and a sixth cam surface is provided at the end of the conjoined cam facing the intermediate gear, and under the elastic force of the elastic assembly, the fifth cam surface abuts against the sixth cam surface. In this way, it is helpful to increase the damping force of the first housing and the second housing rotating around the main axis, thereby improving the opening and closing feel of the user.

[0024] In a possible implementation of the present application, the terminal device further includes a flexible display screen, which continuously covers the first housing and the hinge mechanism, and the flexible display screen is fixedly connected to the first housing. Since the first housing of the terminal device can be stably maintained in a flattened state and a closed state, the first housing can stably support the flexible display screen in the above state, thereby reducing the risk of damage to the flexible display screen, thereby improving the structural reliability of the terminal device.

[0079] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. However, the example implementation can be implemented in various forms and should not be construed as being limited to the implementations set forth herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all illustrated by taking the accompanying drawings as examples, but changes may be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings of the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0080] It should be noted that specific details are described in the following description to facilitate understanding of the present application. However, the embodiments of the present application can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the embodiments of the present application. Therefore, the present application is not limited to the specific implementation methods disclosed below.

[0081] In order to facilitate understanding of the terminal device provided in the embodiment of the present application, its application scenario is first described below. The terminal device may be, but is not limited to, a foldable terminal device such as a smart phone, a personal digital assistant (PDA), a laptop computer, or a tablet computer. Figure 1 , Figure 1 A schematic diagram of the structure of a terminal device provided in an embodiment of the present application. Figure 1 In the illustrated embodiment, the terminal device is in a closed state. In order to realize the foldable function, a hinge mechanism 1 is provided in the terminal device. In addition, the terminal device may further include two shells and a flexible display screen. For ease of explanation, in the present application, the two shells of the terminal device may be named as a first shell 2 and a second shell 3, respectively. Among them, the first shell 2 and the second shell 3 are located on both sides of the hinge mechanism 1, and at least one of the first shell 2 and the second shell 3 can be rotatably connected to the hinge mechanism 1, so that the terminal device can be switched between a flattened state, a closed state, and an intermediate state between the flattened state and the closed state (hereinafter referred to as the intermediate state).

[0082] Reference Figure 2 , Figure 2It is a structural schematic diagram of a terminal device in a flattened state. In this flattened state, the first shell 2 and the second shell 3 are still located on both sides of the hinge mechanism 1. In addition, the surfaces of the first shell 2, the second shell 3 and the hinge mechanism 1 that are used to contact the flexible display screen 4 are approximately in the same plane. Since the flexible display screen 4 can be bonded to the first shell 2 and the second shell 3, the flexible display screen 4 can also be in a flattened state under the support of the first shell 2, the second shell 3 and the hinge mechanism 1, so that the first shell 2, the second shell 3 and the hinge mechanism 1 can support the flexible display screen 4 flatly.

[0083] In the present application, the terminal device can be an outward-folding terminal device or an inward-folding terminal device. In the process of the outward-folding terminal device changing from a flat state to a closed state, the flexible display screen 4 is always located on the outside of the terminal device; while for the inward-folding terminal device, in the process of changing from a flat state to a closed state, the flexible display screen 4 is always located on the inside of the terminal device. Taking the outward-folding terminal device as an example, during the folding process of the terminal device, the first shell 2 and the second shell 3 can be moved along the following lines: Figure 2 The first shell 2 and the second shell 3 are relatively rotated in the direction indicated by the arrowed curve shown in FIG.

[0084] It is understandable that the terminal device consists of Figure 2 The flattened state shown to Figure 1 The closed state shown, or by Figure 1 The closed state shown to Figure 2 The process of the flattened state shown is the process of the first shell 2 and the second shell 3 rotating around the shaft mechanism 1. The holding force of the terminal device in the closed state and the flattened state is an important part that affects the user's opening and closing experience. Figure 1 The closed state shown and Figure 2 The flattened state shown in the figure depends largely on the damping force provided by the shaft mechanism 1, so a damping assembly is usually provided in the shaft mechanism 1. At present, the damping force provided by the damping assembly is mostly achieved by converting the elastic force generated by the spring compression into the shaft torque. In order to provide the damping force that meets the requirements, the spring stiffness coefficient can be increased. However, since the increase in the holding force of the closed state and the flattened state of the terminal device is achieved by increasing the spring stiffness coefficient, when any of the above holding forces is increased, the force value of the opening and closing process will also be increased, which will affect the feel of the entire opening and closing process of the terminal device and affect the user's opening and closing comfort.

[0085] In view of this, the terminal device provided in the embodiment of the present application is provided with adsorbable magnetic parts at the extreme positions corresponding to the closed state and the flattened state, so as to convert the magnetic force into the state holding force of the terminal device, so that the holding force of the closed state and the holding force of the flattened state of the terminal device can be adjusted separately by adjusting the magnetic force of the corresponding magnetic parts separately, which can enable the terminal device to be stably maintained in the closed state and the flattened state while reducing the impact of the force on the opening and closing process, so it can improve the user experience. To facilitate the understanding of the terminal device provided in the embodiment of the present application, its specific structure is described in detail below in conjunction with the accompanying drawings.

[0086] From the above introduction to the terminal device, it can be known that the hinge mechanism 1 is a key component for realizing the foldable function of the terminal device. Based on this, the basic structure of the hinge mechanism 1 of the terminal device for realizing the rotation function is first described. Figure 3 , Figure 3 A schematic diagram of the structure of the rotating shaft mechanism 1 provided in the embodiment of the present application. The rotating shaft mechanism 1 provided in the embodiment of the present application includes a rotating module A, and the rotating module A includes a main shaft 101, a first rotating component 102, and a second rotating component 103. Among them, the main shaft 101 can be used as a bearing component of the rotating module A, and the first rotating component 102 and the second rotating component 103 are located on opposite sides of the main shaft 101, and the first rotating component 102 and the second rotating component 103 are rotatably connected to the main shaft 101. In the present application, the above Figure 1 and Figure 3 The first housing 2 shown in FIG. 1 can be rotatably connected to the main shaft 101 through the first rotating assembly 102. Figure 1 and Figure 3 The second housing 3 shown in the figure can be rotatably connected to the main shaft 101 through the second rotating assembly 103. Based on this, it can be understood that in the present application, the process of the terminal device from the flat state to the closed state is the process in which the first housing 2 and the second housing 3 drive the first rotating assembly 102 and the second rotating assembly 103 to rotate around the main shaft in opposite directions; and the process of the terminal device from the closed state to the flat state is the process in which the first housing 2 and the second housing 3 drive the first rotating assembly 102 and the second rotating assembly 103 to rotate around the main shaft 101 in opposite directions.

[0087] It is worth mentioning that in Figure 3The illustrated rotating shaft mechanism 1 only shows one rotating module A, while the rotating shaft mechanism 1 provided in the embodiment of the present application may include multiple rotating modules A, and the main shafts 101 of the multiple rotating modules A may be sequentially connected along the axial direction of the rotating shaft mechanism 1, so that the arrangement of the multiple rotating modules A of the rotating shaft mechanism 1 is more flexible. In addition, the multiple rotating modules A may also share one main shaft 101 to improve the structural reliability of the rotating shaft mechanism 1. Then the first housing 2 may be rotatably connected to the main shaft 101 through the multiple first rotating components 102 of the multiple rotating modules A, and the second housing 3 may be rotatably connected to the main shaft 101 through the multiple second rotating components 103 of the multiple rotating modules A, thereby improving the stability of the first housing 2 and the second housing 3 rotating around the main shaft 101.

[0088] Reference Figure 4 , Figure 4 for Figure 3 A schematic diagram of the structure of the rotating module of the rotating shaft mechanism 1 is provided. The first rotating assembly 102 includes a first support arm 1021, and the first support arm 1021 is rotatably connected to the main shaft 101. The manner in which the first support arm 1021 is rotatably connected to the main shaft 101 is not limited in this application. For example, Figure 4 In the structure shown, the first support arm 1021 and the main shaft 101 can be rotatably connected by means of a virtual axis. It is worth mentioning that in the present application, the virtual axis refers to the axis of an arc-shaped structure, and the two rotatably connected parts can rotate relative to the virtual axis, and the position of the virtual axis is fixed as the two rotatably connected parts rotate relative to each other.

[0089] When the first support arm 1021 is specifically connected to the main shaft 101, reference may be made to Figure 5 , Figure 5 for Figure 4 The exploded diagram of the rotating module is shown. The main shaft 101 may include a first arc-shaped shaft 1011, and the first support arm 1021 may include a first arc-shaped groove 10211, and the first arc-shaped shaft 1011 may be installed in the first arc-shaped groove 10211, and the first arc-shaped shaft 1011 may slide along the groove surface of the first arc-shaped groove 10211, thereby realizing the rotation connection between the first support arm 1021 and the main shaft 101.

[0090] You can continue to refer to Figure 5 In the present application, the main shaft 101 may include a main inner shaft 101a and a main outer shaft 101b. The main inner shaft 101a and the main outer shaft 101b may be interlocked, and the main inner shaft 101a and the main outer shaft 101b may be fixedly connected by, but not limited to, threaded connection. In the shaft mechanism 1 provided in the embodiment of the present application, the main shaft 101 can effectively reduce the volume of the main shaft 101 by disassembling and assembling.

[0091] It can be understood that in some possible embodiments of the present application, the first arc-shaped axis 1011 can also be set on the first support arm 1021, and the first arc-shaped groove 10211 can be set on the main shaft 101. The rotational connection between the first support arm 1021 and the main shaft 101 can still be achieved by means of a virtual axis such as the sliding of the first arc-shaped axis 1011 in the first arc-shaped groove 10211.

[0092] You can continue to refer to Figure 4 and Figure 5 The first rotating assembly 102 further includes a first swing arm 1022. The first swing arm 1022 and the first support arm 1021 are arranged at intervals along the extension direction of the axis of the main shaft 101. The first swing arm 1022 is also rotatably connected to the main shaft 101. In the present application, the first swing arm 1022 and the main shaft 101 can also be rotatably connected by means of a virtual axis. Figure 5 , the main shaft 101 is provided with a second arc groove 1012. In addition, the first swing arm 1022 is provided with a second arc shaft 10221, and the second arc shaft 10221 can be installed in the second arc groove 1012, and the second arc shaft 10221 can slide along the groove surface of the second arc groove 1012, thereby realizing the rotation connection between the first swing arm 1022 and the main shaft 101.

[0093] In the rotating shaft mechanism 1 provided in the embodiment of the present application, by realizing the rotational connection between the first support arm 1021 and the first swing arm 1022 of the first rotating assembly 102 and the main shaft 101 by means of a virtual shaft, it is advantageous to realize the miniaturized design of the rotating shaft mechanism 1. In addition, the above is only an exemplary description of the specific setting method of the virtual shaft that can realize the rotational connection between the first support arm 1021 and the first swing arm 1022 and the main shaft 101. Based on the above definition of the virtual shaft in the present application, in some other possible embodiments of the present application, the first support arm 1021 and the first swing arm 1022 can also realize the rotational connection with the main shaft 101 by means of other specific virtual shafts. Alternatively, in some embodiments of the present application, at least one of the first support arm 1021 and the first swing arm 1022 can also realize the rotational connection with the main shaft 101 by means of a solid shaft, thereby simplifying the structural design of the rotating shaft mechanism 1 and improving the connection reliability between the first rotating assembly 102 and the main shaft 101.

[0094] You can continue to refer to Figure 4In the rotating shaft mechanism 1 provided in the embodiment of the present application, the axis aa of the first support arm 1021 rotating around the main shaft 101 and the axis bb of the first swing arm 1022 rotating around the main shaft 101 do not coincide with each other, so during the rotation of the first rotating assembly 102 around the main shaft 101, there is a phase difference between the first support arm 1021 and the first swing arm 1022. It is worth mentioning that the axis aa of the first support arm 1021 rotating around the main shaft 101 and the axis bb of the first swing arm 1022 rotating around the main shaft 101 may be parallel or non-parallel, and are not specifically limited in the present application.

[0095] Also refer to Figure 6 , Figure 6 This is a schematic diagram of the structure of the terminal device provided in the embodiment of the present application when it is in a flattened state. In order to facilitate the display of the connection relationship between the first shell 2 and the second shell 3 of the terminal device and the hinge mechanism 1, please refer to Figure 7 , Figure 7 for Figure 6 The enlarged view of the local structure of the terminal device at B shown in FIG. Among them, the first support arm 1021 is fixedly connected to the first shell 2. In addition, the first swing arm 1022 is slidably connected to the first shell 2. In specific implementation, the first shell 2 may be provided with a first slide 201, and the end of the first swing arm 1022 away from the main shaft 101 has a first slider 10222, and the first slider 10222 is installed on the first slide 201. Then, during the folding process of the terminal device, the first rotating assembly 102 rotates around the main shaft 101, and the first slider 10222 can slide in the first slide 201, thereby realizing the relative sliding of the first swing arm 1022 and the first shell 2. In the present application, the direction of the relative sliding of the first swing arm 1022 and the first shell 2 is not limited. For example, the direction of the relative sliding of the first shell 2 and the first swing arm 1022 may be perpendicular to the axis of the main shaft 101, or the direction of the relative sliding of the first shell 2 and the first swing arm 1022 has a component perpendicular to the axis of the main shaft 101.

[0096] It is worth mentioning that in the embodiment of the present application, the first support arm 1021 can be directly fixedly connected to the first shell 2, and its fixing method can be but not limited to threaded connection. Alternatively, the first support arm 1021 can also be indirectly connected to the first shell 2 through other structures, for example, refer to Figure 8 , Figure 8 for Figure 7An exploded view of a partial structure of a terminal device is shown in the figure, and the terminal device may further include a first housing fixing frame 5, and the first housing fixing frame 5 may be fixedly connected to the first housing 2, and the first support arm 1021 is fixedly connected to the first housing fixing frame 5, thereby realizing an indirect connection between the first support arm 1021 and the first housing 2. In addition, when the terminal device includes the first housing fixing frame 5, the first slideway 201 may also be arranged on the first housing fixing frame 5, so that the first swing arm 1022 and the first housing 2 slide relative to each other through the sliding of the first slider 10222 of the first swing arm 1022 relative to the first housing fixing frame 5.

[0097] Since the relative positions of the first swing arm 1022 and the first shell 2 are different when the terminal device is in the closed state and the flattened state, based on this, the relative sliding of the first swing arm 1022 and the first shell 2 can be constrained by force at the extreme position of the relative sliding of the first shell 2 and the first swing arm 1022 when the terminal device is in the closed state and the flattened state, thereby achieving the purpose of increasing the holding force of the first shell 2 when the terminal device is in the closed state and the flattened state, so that the first shell 2 can be stably maintained in the corresponding state.

[0098] When implementing it, please continue to refer to Figure 8 The terminal device may further include a first magnetic component 104, and the first magnetic component 104 is fixedly connected to the first shell 2. In the present application, the implementation method of the fixed connection between the first magnetic component 104 and the first shell 2 is not specifically limited. For example, in Figure 8 In the terminal device shown, the first magnetic component 104 may be embedded in the first side wall 202 of the first shell 2, and the first side wall 202 is arranged toward the hinge mechanism 1. In other possible embodiments, the first magnetic component 104 may also be fixedly connected to the first shell 2 by bonding or clamping.

[0099] In addition, the terminal device further includes a first sliding module 1042, and the first sliding module 1042 is fixedly connected to the first swing arm 1022, so that the first sliding module 1042 can slide relative to the first housing 2 along with the first swing arm 1022. Figure 8 , the first side wall 202 may be provided with a first avoidance hole 2021 , and a portion of the first sliding module 1042 may pass through the first avoidance hole 2021 .

[0100] Can be referred to together Figure 7 and Figure 8The first sliding module 1042 includes a first magnetic member 10421 and a second magnetic member 10422, which are respectively arranged on both sides of the first side wall 202, and the first magnetic member 10421 is located on the side of the second magnetic member 10422 away from the main shaft 101, and the first magnetic component 104 can be located between the first magnetic member 10421 and the second magnetic member 10422. Figure 7 In the flattened state shown, the first magnetic part 10421 is attracted to the first magnetic component 104, and the magnetic force between the first magnetic part 10421 and the first magnetic component can limit the relative sliding of the first sliding module 1042 and the first shell 2, thereby limiting the relative sliding of the first swing arm 1022 and the first shell 2, so that the first shell 2 of the terminal device can be stably maintained in the flattened state.

[0101] It is understandable that in the terminal device provided in the embodiment of the present application, the magnetic force between the first magnetic component 104 and the first magnetic component 104 can be adjusted by adjusting the size and quantity of the first magnetic component 104, thereby adjusting the holding force of the first shell 2 of the terminal device to maintain it in a flat state. Figure 8 In the terminal device shown, the first magnetic component 104 may include two magnetic parts, and there may also be two first magnetic parts 10421, and the two magnetic parts of the first magnetic component 104 and the two first magnetic parts 10421 are adsorbed one by one, so that there is a sufficiently large magnetic force between the first sliding module 1042 and the first shell 2, so that there is sufficient state retention force between the first swing arm 1022 and the first shell 2.

[0102] The specific configuration of the first sliding module 1042 is not limited in the present application. For example, please continue to refer to Figure 8 The first sliding module 1042 may include a first fixed portion 10423 and a first extending portion 10424 connected to each other, wherein the first fixed portion 10423 is fixedly connected to the first swing arm 1022, and the first extending portion 10424 extends in a direction away from the first fixed portion 10423. Figure 7 and Figure 8 , the first extension portion 10424 can pass through the first avoidance hole 2021, the first magnetic member 10421 can be disposed at the end of the first extension portion 10424 away from the first fixing portion 10423, and the second magnetic member 10422 can be disposed at the first fixing portion 10423. Figure 7 and Figure 8 In the first sliding module 1042 shown, the first fixing portion 10423 and the first extending portion 10424 may be vertically arranged.

[0103] In the terminal device provided in the embodiment of the present application, the first sliding module 1042 and the first swing arm 1022 can be an integrally formed structure. Specifically, the first fixing portion 10423 of the first sliding module 1042 and the first sliding block 10222 of the first swing arm 1022 can be the same structure, which is conducive to improving the integration of the terminal device, thereby helping to simplify the structure of the terminal device. In some other possible embodiments of the present application, the first swing arm 1022 and the first sliding module 1042 can also be an assembled structure. For example, the first sliding block 10222 of the first swing arm 1022 can be provided with a mounting groove ( Figure 8 ), the first fixing portion 10423 can be installed in the installation slot. In addition, the first fixing portion 10423 can be fixedly connected to the slot wall of the installation slot by, but not limited to, bonding, riveting, clamping or threaded connection, so as to achieve a fixed connection between the first fixing portion 10423 and the first swing arm 1022.

[0104] It is understandable that in the process of opening the terminal device, it is necessary to overcome the magnetic force between the first magnetic member 10421 and the first magnetic assembly 104. In the terminal device provided in the embodiment of the present application, the magnetic force between the first magnetic assembly 104 and the first magnetic member 10421 can be adjusted by changing the size and quantity thereof, thereby adjusting the opening force of the terminal device, which is conducive to improving the user's opening feel.

[0105] Reference Fig. 9 , Fig. 9 This is a schematic diagram of a structure of a terminal device provided in an embodiment of the present application when it is in an intermediate state. In order to facilitate the display of the relative position between the first sliding module 1042 and the first housing 2 of the terminal device in the intermediate state, please refer to Fig.10 , Fig.10 for Fig. 9 The enlarged view of the local structure of the terminal device at C shown in FIG. Figure 7 and Fig. 9 It can be seen that the terminal device is composed of Figure 7 The expanded state shown to Fig. 9During the intermediate state shown, the first shell 2 slides relative to the first sliding module 1042 toward the main axis 101 of the hinge mechanism 1, and the first shell 2 slides relative to the first swing arm 1022 toward the main axis 101, so that the first magnetic component 104 moves toward the main axis 101 relative to the first magnetic part 10421, so that the first magnetic part 10421 is separated from the first magnetic component 104, then when the terminal device is in the intermediate state, the first magnetic component 104 is separated from the first magnetic part 10421, and the first magnetic component 104 is separated from the second magnetic part 10422, then the arrangement of the first magnetic component 104 and the first sliding module 1042 has little effect on the process force of the first shell 2 rotating around the hinge mechanism 1 during the process of the terminal device changing from the expanded state to the closed state.

[0106] It is understandable that the terminal device consists of Fig.10 In the process from the intermediate state to the closed state, the first housing 2 continues to move toward the main shaft 101 relative to the first sliding module 1042, so that the distance between the first magnetic component 104 and the first magnetic member 10421 is further increased, while the distance between the first magnetic component 104 and the second magnetic member 10422 is reduced. Fig.11 , Fig.11 A schematic diagram of a structure of a terminal device in a closed state provided in an embodiment of the present application, Fig.11 In order to show the relative position between the first sliding module 1042 and the first housing 2 in the closed state of the terminal device, please refer to Fig.12 , Fig.12 for Fig.11 The enlarged view of the local structure at D of the terminal device shown in FIG. When the terminal device is in a closed state, the second magnetic member 10422 is attracted to the first magnetic component 104, and the first sliding module 1042 and the first shell 2 no longer slide relative to each other without the action of external force. The magnetic force between the second magnetic member 10422 and the first magnetic component 104 limits the relative sliding between the first shell 2 and the first swing arm 1022, so that the first shell 2 of the terminal device can be stably maintained in the closed state.

[0107] In addition, in the terminal device provided in the embodiment of the present application, the magnetic force between the first magnetic component 104 and the second magnetic component 10422 can be adjusted by adjusting the size and quantity thereof, thereby adjusting the holding force of the first shell 2 of the terminal device in the closed state. Fig.12In the terminal device shown, the first magnetic component 104 includes two magnetic parts, and there can be two second magnetic parts 10422, and the two magnetic parts of the first magnetic component 104 and the two second magnetic parts 10422 are adsorbed one by one, so that there is a sufficiently large state retention force between the first sliding module 1042 and the first shell 2.

[0108] It is worth mentioning that, since in the terminal device provided in the embodiment of the present application, magnetic parts that can be attracted to each other are only arranged between the first shell 2 and the first swing arm 1022 at the extreme positions corresponding to the flattened state and the closed state, in the process of adjusting the magnetic force between the above-mentioned magnetic parts that can be attracted to each other, the influence on the opening and closing process force of the terminal device is small, thereby improving the smoothness of the user's opening and closing process operation, which is beneficial to improving the user's experience.

[0109] In summary, in the terminal device provided in the embodiment of the present application, the first magnetic component 104 and the first sliding module 1042 are arranged between the hinge mechanism 1 and the first shell 2, so that the first sliding module 1042 fixedly connected to the first swing arm 1022 can slide relative to the first shell 2 during the folding process of the terminal device, so that a pair of magnetic parts are attracted to each other when the terminal device is in a flattened state, so that the first shell 2 can be stably maintained in the flattened state. In addition, when the terminal device is in a closed state, another pair of magnetic parts are attracted to each other, so that the first shell 2 can be stably maintained in a closed state. In this way, the state retention force of the first shell 2 when the terminal device is in a closed state and a flattened state can be separately adjusted by separately adjusting the magnetic force between the corresponding magnetic parts, so that the first shell 2 can be stably maintained in the corresponding state, and the influence of the force on the opening and closing process can be effectively reduced to enhance the user's comfort in opening and closing.

[0110] In the above embodiment of the present application, the generation method of the state retention force of the first shell 2 of the terminal device in the closed state and the flattened state is introduced. When the second shell 3 can also rotate around the main axis, a retention force corresponding to the closed state and the flattened state of the terminal device can also be generated between the rotating shaft mechanism 1 and the second shell 3, so that the second shell 3 can be stably maintained in the corresponding state, so that the terminal device can be stably maintained in the closed state and the flattened state.

[0111] For specific implementation, please refer to Fig.13 , Fig.13 for Figure 4Another exploded view of the rotating module shown. In the present application, the second rotating assembly 103 includes a second support arm 1031, and the second support arm 1031 is rotatably connected to the main shaft 101, wherein the connection method between the second support arm 1031 and the main shaft 101 is similar to the connection method between the first support arm 1021 and the main shaft 101, and illustratively, the second support arm 1031 includes a third arc groove 10311, and the main shaft 101 includes a third arc shaft 1013, and the third arc shaft 1013 can slide along the groove surface of the third arc groove 10311, thereby realizing the rotational connection between the second support arm 1031 and the main shaft 101.

[0112] You can continue to refer to Fig.13 The second rotating component 103 also includes a second swing arm 1032, and the second swing arm 1032 is provided with a fourth arc-shaped shaft 10321, and the main shaft 101 can be provided with a fourth arc-shaped groove 1014, the fourth arc-shaped shaft 10321 can be installed in the fourth arc-shaped groove 1014, and the fourth arc-shaped shaft 10321 can slide along the groove surface of the fourth arc-shaped groove 1014, thereby realizing the rotational connection between the second swing arm 1032 and the main shaft 101.

[0113] In addition, refer to Fig.14 , Fig.14 for Fig.13 The exploded view of the structure at E of the structure shown in FIG. The second swing arm 1032 includes a second slider 10322, and the fourth arc-shaped shaft 10321 is fixedly connected to the second slider 10322. The second slider 10322 is provided with a slide groove 103221, and the side wall of the slide groove 103221 facing the fourth arc-shaped shaft 10321 is provided with an opening 1032211. In addition, the second swing arm 1032 may also include a cover plate 10323, and the cover plate 10323 is covered on the notch of the slide groove 103221.

[0114] like Fig.14 As shown, the shaft mechanism 1 further includes a first damping assembly 105, which can be installed in the slide groove 103221, and the first damping assembly 105 slides in the slide groove 103221 relative to the second swing arm 1032 in a direction toward or away from the main shaft 101. When specifically setting the first damping assembly 105, reference can be made to Fig.15 , Fig.15An exploded view of the first damping assembly 105 provided in the embodiment of the present application. The first damping assembly 105 includes a roller 1051, a damping module 1052 and a spring 1053. The roller 1051 is rotatably connected to the end of the damping module 1052 through a roller shaft 1054, and the roller 1051 can extend to the opening 1032211 of the slide slot 103221. The spring 1053 is arranged on the side of the damping module 1052 away from the roller 1051, and one end of the spring 1053 is elastically connected to the damping module 1052. It is worth mentioning that in the embodiment of the present application, the specific number of springs 1053 can be set according to the magnitude of the damping force to be provided by the first damping assembly 105, the space of the slide slot 103221, etc. In addition, a guide rod 10521 may be provided at the end of the damping module 1052 facing away from the roller 1051, and the spring 1053 may be sleeved on the guide rod 10521, which can avoid problems such as arching of the spring 1053 when elastic deformation occurs, thereby helping to improve the movement reliability of the damping module 1052.

[0115] You can continue to refer to Fig.13 , the main shaft 101 may be provided with a cam member 1015, and the roller 1051 of the first damping assembly 105 may abut against the cam surface of the cam member 1015. Fig.16a , Fig.16a for Figure 4 The FF cross-sectional view of the shaft module shown in FIG. Fig.16a The diagram shows the relative positions of the first damping assembly 105 and the main shaft 101 when the terminal device is in a flattened state. At this time, the spring 1053 presses the damping module 1052 toward the cam member 1015 of the main shaft 101 so that the roller 1051 abuts against the cam surface of the cam member 1015 .

[0116] In addition, refer to Fig.16b , Fig.16b for Fig.16a The structure shown in is a schematic diagram of the structure when the terminal device is in the intermediate state. Fig.16a and Fig.16b It can be seen that when the terminal device moves from the flattened state to the intermediate state, the damping module 1052 slides relative to the second swing arm 1032 in a direction away from the main axis 101, so that the length of the spring 1053 is reduced, thereby increasing the compression of the spring 1053.

[0117] Based on this, it can be understood that when the terminal device is in different folded states, the spring 1053 is compressed or stretched to different degrees, so the stored elastic force is different, so that the damping force received by the second swing arm 1032 during the rotation relative to the main shaft 101 is different. Based on this, the state retention force of the second swing arm 1032 when the terminal device is in the closed state and the flattened state can be adjusted by reasonably designing the elastic force of the spring 1053 and the specific shape of the cam surface, so that the second swing arm 1032 can be stably maintained in the above-mentioned closed state and the flattened state.

[0118] In addition, in the rotating device provided in the embodiment of the present application, the second swing arm 1032 can be slidably connected to the second housing 3. Figure 7 , the second housing 3 may be provided with a second slideway 301, and the second slider 10322 of the second swing arm 1032 is installed on the second slideway 301. In addition, the second support arm 1031 is fixedly connected to the second housing 3. Based on the introduction of the relationship between the first support arm 1021 and the first swing arm 1022 and the main shaft 101 in the above text of this application, it can be known that in the terminal device provided in the embodiment of this application, the axis of rotation of the second support arm 1031 and the second swing arm 1032 around the main shaft 101 does not coincide, then in the process of the second rotating assembly 103 rotating around the main shaft 101 with the second housing 3, there is a phase difference between the second swing arm 1032 and the second support arm 1031, then the second swing arm 1032 can slide relative to the second housing 3, thereby realizing the relative sliding of the second housing 3 and the second swing arm 1032 in the direction toward or away from the main shaft 101.

[0119] It can be understood that, when the second swing arm 1032 slides relative to the second shell 3, the damping force exerted on the second swing arm 1032 by the first damping assembly 105 can be transmitted to the second shell 3, so that the second shell 3 can be stably maintained in the closed state and the flattened state.

[0120] In the terminal device provided in the above-mentioned embodiment of the present application, by setting a first magnetic component 104 between the first shell 2 and the hinge mechanism 1, and setting a first damping component 105 between the second shell 3 and the hinge mechanism 1, the first shell 2 and the second shell 3 can be stably maintained in corresponding states when the terminal device is in a closed state and a flattened state.

[0121] Reference Fig.17 , Fig.17 This is another schematic diagram of the structure of the terminal device provided in the embodiment of the present application when it is in a flattened state. Fig.17 In the terminal device shown, the holding force that enables the second housing 3 to stably maintain the flattened state is also provided by the magnetic member that is attracted to each other, rather than by the first damping component mentioned above. Fig.18 , Fig.18 for Fig.17 The terminal device further includes a second magnetic component 106, which is disposed on the second side wall 302 of the second housing 3, and the second side wall 302 is disposed toward the hinge mechanism 1. The manner in which the second magnetic component 106 is connected to the second housing 3 can be specifically configured with reference to the manner in which the first magnetic component 104 is connected to the first housing 2 in the above embodiment, and will not be described in detail herein. In addition, the second side wall 302 is provided with a second avoidance hole 3021, and a portion of the second sliding module 1062 passes through the second avoidance hole 3021.

[0122] In addition, the terminal device further includes a second sliding module 1062, and the second sliding module 1062 is fixedly connected to the second swing arm 1032, so that the second sliding module 1062 can slide relative to the second housing 3 along with the second swing arm 1032. The second sliding module 1062 can be specifically configured with reference to the first sliding module 1042. In short, the second sliding module 1062 includes a fifth magnetic component 10621 and a sixth magnetic component 10622, and the fifth magnetic component 10621 and the sixth magnetic component 10622 can be located on both sides of the second side wall 302, and the fifth magnetic component 10621 is located on the side of the sixth magnetic component 10622 away from the main shaft 101, and the second magnetic component 106 is located between the fifth magnetic component 10621 and the sixth magnetic component 10622. When the terminal device is in Fig.18 In the flattened state shown, the fifth magnetic part 10621 is attracted to the second magnetic component 106, and the magnetic force between the fifth magnetic part 10621 and the second magnetic component 106 can limit the relative sliding of the second sliding module 1062 and the second shell 3, thereby limiting the relative sliding of the second swing arm 1032 and the second shell 3, so that the second shell 3 can be stably maintained in the flattened state.

[0123] In addition, the second sliding module 1062 may include a second fixed portion 10623 and a second extending portion 10624 connected to each other, the second fixed portion 10623 is fixedly connected to the second swing arm 1032, and the second extending portion 10624 extends in a direction away from the second fixed portion 10623. The fifth magnetic member 10621 may be disposed at an end of the second extending portion 10624 away from the second fixed portion 10623, and the sixth magnetic member 10622 may be disposed at the second fixed portion 10623. In addition, the second fixed portion 10623 and the second extending portion 10624 may be disposed vertically.

[0124] In the terminal device provided in the embodiment of the present application, the second fixing portion 10623 of the second sliding module 1062 is connected to the Fig.14The second slider 10322 of the second swing arm 1032 shown in the figure can be of the same structure, and the second sliding module 1062 and the second swing arm 1032 can be an integrally formed structure. Alternatively, the second swing arm 1032 and the second sliding module 1062 can also be an assembled structure, and the second fixing portion 10623 can be installed in the slide groove 103221 of the second slider 10322, and the second fixing portion 10623 can be fixedly connected to the slide groove 103221.

[0125] It can be understood that in the terminal device provided in the embodiment of the present application, the magnetic force between the second magnetic component 106 and the fifth magnetic component 10621 can be adjusted by adjusting the size and quantity of the two, thereby adjusting the holding force of the second shell 3 of the terminal device to maintain it in a flat state, that is, adjusting the opening force of the terminal device, which is beneficial to improving the user's opening feel.

[0126] In addition, when the terminal device is in a closed state, the sixth magnetic part 10622 is adsorbed with the second magnetic component 106, and the second sliding module 1062 and the second shell 3 no longer slide relative to each other in the absence of external force. The magnetic force between the sixth magnetic part 10622 and the second magnetic component 106 limits the relative sliding between the second shell 3 and the second swing arm 1032, thereby allowing the second shell 3 of the terminal device to be stably maintained in the closed state.

[0127] The other structures of the second magnetic component 106 can be set with reference to the first magnetic component 104, and in the process of the terminal device changing from a flat state to a closed state, the relative movement relationship between the second shell 3 and the second sliding module 1062 is similar to the relative movement relationship between the first shell 2 and the first sliding module 1042, and they will not be repeated here.

[0128] In the terminal device provided in the embodiment of the present application, the first magnetic component 104 and the first sliding module 1042 can be arranged between the hinge mechanism 1 and the first shell 2, and the second magnetic component 106 and the second sliding module 1062 can be arranged between the hinge mechanism 1 and the second shell 3, so that during the folding process of the terminal device, the first sliding module 1042 fixedly connected to the first swing arm 1022 can slide relative to the first shell 2, and the second sliding module 1062 fixedly connected to the second swing arm 1032 can slide relative to the second shell 3, so that when the terminal device is in a flattened state, the first magnetic component 104 is adsorbed with a magnetic part of the first sliding module 1042, and the second magnetic component 106 is adsorbed with a magnetic part of the second sliding module 1062, so that the first shell 2 and the second shell 3 can be stably maintained in the flattened state. In addition, when the terminal device is in a closed state, the first magnetic component 104 is adsorbed with another magnetic part of the first sliding module 1042, and the second magnetic component 106 is adsorbed with another magnetic part of the second sliding module 1062, so that the first shell 2 and the second shell 3 can be stably maintained in a closed state. In this way, the state retention force of the first shell 2 and the second shell 3 when the terminal device is in a closed state and a flattened state can be individually adjusted by individually adjusting the magnetic force between the corresponding magnetic parts. This can ensure that the first shell 2 and the second shell 3 are stably maintained in the corresponding state while effectively reducing the impact of the force on the opening and closing process of the terminal device, thereby improving the user's opening and closing comfort.

[0129] Based on the design principle of the magnetic assembly between the housing and the shaft mechanism in the above embodiments of the present application, some reasonable modifications can be made to the specific structure of the magnetic assembly. Fig.19 , Fig.19 Another structural schematic diagram of a terminal device provided in an embodiment of the present application when it is in a flattened state. Fig.19 In the terminal device shown in FIG. 1 , the arrangement of the first magnetic component 104 and the first sliding module 1042 and the relative movement of the first sliding module 1042 and the first housing 2 are slightly different from those in the above embodiment. For details, please refer to FIG. Fig.20a , Fig.20a for Fig.19 The enlarged view of the local structure of the terminal device at H is shown in FIG. The first housing 2 may be provided with a first mounting groove 203, and the first mounting groove 203 is connected to the first avoidance hole 2021 of the first side wall 202. For ease of description, please refer to Fig.20b , Fig.20b for Fig.20aThe exploded view of the local structure is shown in FIG. The first magnetic assembly 104 includes a third magnetic member 1041a and a fourth magnetic member 1041b that are spaced apart. The first mounting groove 203 includes two groove walls that are oppositely disposed, and the third magnetic member 1041a and the fourth magnetic member 1041b are respectively disposed on the two groove walls. The third magnetic member 1041a and the fourth magnetic member 1041b can be, but are not limited to, spaced apart in a direction parallel to the axis of the main shaft.

[0130] In addition, the first magnetic member 10421 and the second magnetic member 10422 are still arranged on the first sliding module 1042, and the first magnetic member 10421 can be located between the third magnetic member 1041a and the fourth magnetic member 1041b, and the second magnetic member 10422 is located between the third magnetic member 1041a and the fourth magnetic member 1041b, and the first magnetic member 10421 is arranged close to the third magnetic member 1041a relative to the second magnetic member 10422, and the second magnetic member 10422 is arranged close to the fourth magnetic member 1041b relative to the first magnetic member 10421. Fig.20a In the flattened state shown, the first magnetic member 10421 and the third magnetic member 1041 a are attracted to each other, and the magnetic force between the first magnetic member 10421 and the third magnetic member 1041 a can limit the relative sliding between the first housing 2 and the first swing arm 1022 .

[0131] In the terminal device provided in the embodiment of the present application, the magnetic force between the third magnetic part 1041a and the first magnetic part 10421 can be adjusted by adjusting the size and quantity of the two, thereby adjusting the holding force of the first shell 2 of the terminal device to maintain it in a closed state.

[0132] exist Fig.20a and Fig.20b In the terminal device shown, in order to enable the first magnetic member 10421 and the second magnetic member 10422 to be attracted to the corresponding third magnetic member 1041a and the fourth magnetic member 1041b in the process of sliding with the first sliding module 1042 relative to the first housing 2, the sliding direction of the first sliding module 1042 relative to the first housing 2 can have a component along the arrangement direction of the third magnetic member 1041a to the fourth magnetic member 1041b. In specific implementation, the first sliding module 1042 includes a first sliding portion 10425 and a second sliding portion 10426 connected to each other, wherein the first sliding portion 10425 can be installed in the first installation groove 203, and the first magnetic member 10421 and the second magnetic member 10422 are respectively arranged at two opposite ends of the first sliding portion 10425. In addition, the second sliding portion 10426 is slidably connected to the first swing arm 1022 through the first avoidance hole 2021.

[0133] In order to convert the relative sliding between the first swing arm 1022 and the first housing 2 into the relative sliding between the first sliding module 1042 and the first housing 2, the first swing arm 1022 may be provided with a first track groove 10223. The second sliding portion 10426 is provided with a first guide column 104261, and the first guide column 104261 is inserted into the first track groove 10223, and the first guide column 104261 can slide along the first track groove 10223. In addition, the angle between the extension direction of the first track groove 10223 and the axial direction of the main shaft 101 includes an acute angle.

[0134] The shape of the first track groove 10223 is not limited in the present application, and it can be a linear groove or a non-linear groove, etc., as long as the first swing arm 1022 can slide relative to the first housing 2 in a direction perpendicular to the axis of the main shaft 101, and the first sliding part 10425 can be driven to slide relative to the first housing 2 in a direction parallel to the axis of the main shaft 101 in the first installation groove 203. In addition, in the present application, when the first track groove 10223 is a non-linear groove, the extension direction of the first track groove 10223 can be understood as the extension direction of the line connecting the two ends of the first track groove 10223.

[0135] exist Fig.20a In the terminal device shown, the relative sliding direction between the first sliding portion 10425 of the first sliding module 1042 and the first shell 2 is parallel to the axis of the main shaft 101, so that the first magnetic component 104 occupies a smaller space in the first shell 2, which is beneficial to improving the space utilization of the first shell 2.

[0136] Reference Fig.21 , Fig.21 Another structural schematic diagram of the terminal device provided in the embodiment of the present application when it is in an intermediate state. In order to facilitate the display of the relative position between the first sliding module 1042 and the first housing 2 of the terminal device in the intermediate state, please refer to Fig. 22 , Fig. 22 for Fig.21 The enlarged view of the local structure at I of the terminal device shown in FIG. Fig.20a and Fig. 22 It can be seen that the terminal device is composed of Fig.20a The expanded state shown to Fig. 22During the intermediate state shown, the first shell 2 slides relative to the first swing arm 1022 in the direction of the main shaft 101, and the second sliding portion 10426 slides along the first track groove 10223 relative to the first swing arm 1022 in the direction of the main shaft 101, so that the first sliding portion 10425 slides in the first mounting groove 203 along the direction from the third magnetic component 1041a to the fourth magnetic component 1041b, so that the first magnetic component 10421 is separated from the third magnetic component 1041a. When the terminal device is in the intermediate state, the third magnetic component 1041a is separated from the first magnetic component 10421, and the fourth magnetic component 1041b is separated from the second magnetic component 10422. The setting of the first magnetic component 104 has little effect on the process force of the first shell 2 rotating around the hinge mechanism 1 during the process of the terminal device changing from the expanded state to the closed state.

[0137] It is understandable that the terminal device consists of Fig. 22 In the process from the intermediate state to the closed state, the first housing 2 continues to move toward the main shaft 101 relative to the first swing arm 1022, which can further increase the distance between the third magnetic member 1041a and the first magnetic member 10421, while reducing the distance between the fourth magnetic member 1041b and the second magnetic member 10422. Fig.23 , Fig.23 Another structural schematic diagram of a terminal device in a closed state provided in an embodiment of the present application, Fig.23 In order to show the relative position between the first sliding module 1042 and the first housing 2 in the closed state of the terminal device, please refer to Fig.24 , Fig.24 for Fig.23 The enlarged view of the local structure at J of the terminal device shown in FIG. When the terminal device is in a closed state, the second magnetic member 10422 and the fourth magnetic member 1041b are attracted to each other, and the first sliding module 1042 and the first shell 2 no longer slide relative to each other without the action of external force. The magnetic force between the second magnetic member 10422 and the fourth magnetic member 1041b limits the relative sliding between the first shell 2 and the first swing arm 1022, so that the first shell 2 of the terminal device can be stably maintained in the closed state.

[0138] In addition, in the terminal device provided in the embodiment of the present application, the magnetic force between the fourth magnetic part 1041b and the second magnetic part 10422 can be adjusted by adjusting the size and quantity of the second magnetic part 10422, thereby adjusting the holding force of the first shell 2 of the terminal device in a closed state.

[0139] It is worth mentioning that, since in the terminal device provided in the embodiment of the present application, magnetic parts that can be attracted to each other are only arranged between the first shell 2 and the first swing arm 1022 at the extreme positions corresponding to the flattened state and the closed state, in the process of adjusting the magnetic force between the above-mentioned magnetic parts that can be attracted to each other, the influence on the opening and closing process force of the terminal device is small, thereby improving the smoothness of the user's opening and closing process operation, which is beneficial to improving the user's experience.

[0140] In summary, in the terminal device provided in the embodiment of the present application, the first magnetic component 104 and the first sliding module 1042 are arranged between the hinge mechanism 1 and the first shell 2, so that the first sliding module 1042 fixedly connected to the first swing arm 1022 can slide relative to the first shell 2 during the folding process of the terminal device, so that a pair of magnetic parts are attracted to each other when the terminal device is in a flattened state, so that the first shell 2 can be stably maintained in the flattened state. In addition, when the terminal device is in a closed state, another pair of magnetic parts are attracted to each other, so that the first shell 2 can be stably maintained in a closed state. In this way, the state retention force of the first shell 2 when the terminal device is in a closed state and a flattened state can be separately adjusted by separately adjusting the magnetic force between the corresponding magnetic parts, so that the first shell 2 can be stably maintained in the corresponding state, and the influence of the force on the opening and closing process can be effectively reduced to enhance the user's comfort in opening and closing.

In addition, the second housing 3 is provided with a second mounting groove 303, and the second mounting groove 303 is connected to the second avoidance hole 3021 of the second side wall 302. The second mounting groove 303 includes two groove walls arranged opposite to each other, and the seventh magnetic component 1061a and the eighth magnetic component 1061b are respectively arranged on the two groove walls.

[0142] The terminal device further includes a second sliding module 1062, and the second sliding module 1062 includes a fifth magnetic member 10621 and a sixth magnetic member 10622, wherein the fifth magnetic member 10621 is located between the seventh magnetic member 1061a and the eighth magnetic member 1061b, and the sixth magnetic member 10622 is located between the seventh magnetic member 1061a and the eighth magnetic member 1061b, and the fifth magnetic member 10621 is arranged close to the seventh magnetic member 1061a relative to the sixth magnetic member 10622, and the sixth magnetic member 10622 is arranged close to the eighth magnetic member 1061b relative to the fifth magnetic member 10621. Fig.26 In the flattened state shown, the fifth magnetic member 10621 and the seventh magnetic member 1061 a are attracted to each other, and the magnetic force between the fifth magnetic member 10621 and the seventh magnetic member 1061 a can limit the relative sliding between the second housing 3 and the second swing arm 1032 .

[0143] In the terminal device provided in the embodiment of the present application, the magnetic force between the fifth magnetic part 10621 and the seventh magnetic part 1061a can be adjusted by adjusting the size and quantity of the two, thereby adjusting the holding force of the second shell 3 of the terminal device to maintain it in a closed state.

In addition, the angle between the extension direction of the second track groove 10324 and the axial direction of the main shaft 101 includes an acute angle.

[0146] The shape of the second track groove 10324 is not limited in the present application, and it can be a linear groove or a non-linear groove, etc., as long as the third sliding part 10625 can be driven to slide relative to the second housing 3 in the direction parallel to the axis of the main shaft 101 in the second installation groove 303 when the second swing arm 1032 slides relative to the second housing 3 in the direction perpendicular to the axis of the main shaft 101. In addition, in the present application, when the second track groove 10324 is a non-linear groove, the extension direction of the second track groove 10324 can be understood as the extension direction of the line connecting the two ends of the second track groove 10324.

[0147] exist Fig.26 In the terminal device shown, the relative sliding direction between the third sliding portion 10625 of the second sliding module 1062 and the second shell 3 is parallel to the axis of the main shaft 101, so that the second magnetic component 106 occupies less space in the second shell 3, which is beneficial to improving the space utilization of the second shell 3.

[0148] In addition, when the terminal device is in a closed state, the sixth magnetic component 10622 and the eighth magnetic component 1061b are attracted to each other, and the second sliding module 1062 and the second shell 3 no longer slide relative to each other in the absence of external force. The magnetic force between the sixth magnetic component 10622 and the eighth magnetic component 1061b limits the relative sliding between the second shell 3 and the second swing arm 1032, thereby allowing the second shell 3 of the terminal device to be stably maintained in the closed state.

[0149] The other structures of the second magnetic component 106 can be set with reference to the first magnetic component 104, and the other structures of the second sliding module 1062 can be set with reference to the first sliding module 1042. In the process of the terminal device changing from a flat state to a closed state, the relative movement relationship between the second shell 3 and the second sliding module 1062 is similar to the relative movement relationship between the first shell 2 and the first sliding module 1042, and they will not be repeated here.

This can ensure that the first shell 2 and the second shell 3 are stably maintained in the corresponding state while effectively reducing the impact of the force on the opening and closing process of the terminal device, thereby improving the user's opening and closing comfort.

In some possible embodiments of the present application, the cooperation between the first magnetic component 104 and the first sliding module 1042 can be arranged differently from the cooperation between the second magnetic component 106 and the second sliding module 1062.

[0153] For specific implementation, please refer to Fig.29 , Fig.29 for Fig.28 The first housing 2 includes a third slideway 204, the first gear connecting rod 1071 includes a first connecting rod 10711, the first connecting rod 10711 is inserted in the third slideway 204, and the first connecting rod 10711 can slide in the third slideway 204 along a direction perpendicular to the axis of the main shaft 101. The second housing 3 includes a fourth slideway 304, the second gear connecting rod 1072 includes a second connecting rod 10721, the second connecting rod 10721 is inserted in the fourth slideway 304, and the second connecting rod 10721 can slide in the fourth slideway 304 along a direction perpendicular to the axis of the main shaft 101.

[0154] Reference Fig.30 , Fig.30 A schematic diagram of the structure of the second damping assembly 107 provided in an embodiment of the present application. The first gear connecting rod 1071 further includes a first gear 10712, which is rotatably connected to the main shaft 101, and the second gear connecting rod 1072 further includes a second gear 10722, which is rotatably connected to the main shaft 101.

[0155] Reference Fig.31 , Fig.31 for Fig.30An exploded view of the second damping assembly 107 is shown. The second damping assembly 107 further includes a conjoined cam 1073 and an elastic assembly 1074. The conjoined cam 1073 is located between the first gear 10712 and the elastic assembly 1074, and the conjoined cam 1073 is located between the second gear 10722 and the elastic assembly 1074, the end of the first gear 10712 facing the conjoined cam 1073 has a first cam surface 107121, the end of the second gear facing the conjoined cam 1073 has a second cam surface 107221, the end of the conjoined cam 1073 facing the first gear has a third cam surface 10731, and the end of the conjoined cam 1073 facing the second gear has a fourth cam surface 10732. The elastic component 1074 presses the integrated cam 1073 toward the first gear 10712 and the second gear 10722 , so that under the elastic force of the elastic component 1074 , the first cam surface 107121 abuts against the third cam surface 10731 , and the second cam surface 107221 abuts against the fourth cam surface 10732 .

[0156] It is worth mentioning that in the present application, the cam surface may include a plurality of protrusions and recesses. When the inclined surfaces of the protrusions of two cam surfaces come into contact with each other, a damping force may be generated between the two cam surfaces to prevent the two cam surfaces from continuing to rotate relative to each other. During the process of the first gear link 1071 and the second gear link 1072 rotating around the main axis, a damping force that hinders the first gear link 1071 from rotating around the main axis 101 can be generated between the first cam surface 107121 and the third cam surface 10731, and a damping force that hinders the second gear link 1072 from rotating around the main axis can be generated between the second cam surface 107221 and the fourth cam surface 10732. Because the first link 10711 of the first gear link 1071 is slidingly connected to the first shell 2, and the second link 10721 of the second gear link 1072 is slidingly connected to the second shell 3, the damping force on the first gear link 1071 can be transmitted to the first shell 2, and the damping force on the second gear link 1072 can be transmitted to the second shell 3. In this way, when the user unfolds or closes the terminal device, the user will have a more obvious sense of frustration, which is beneficial to improving the user experience.

[0157] exist Fig.30In the provided second damping assembly 107, the first gear 10712 and the second gear 10722 can also be connected by an even number of intermediate gears 1075, so that when the first gear link 1071 rotates around the main axis 101, the second gear link 1072 can be driven to rotate synchronously in the opposite direction around the main axis 101. Because the first link 10711 of the first gear link 1071 is slidingly connected to the first shell 2, and the second link 10721 of the second gear link 1072 is slidingly connected to the second shell 3, it can realize the synchronous opposite rotation of the first shell 2 and the second shell 3, which is beneficial to improving the folding reliability of the terminal device.

[0158] In addition, a fifth cam surface 10751 may be provided at the end of each intermediate gear 1075 facing the integrated cam 1073, and a sixth cam surface 10733 may be provided at the end of the integrated cam 1073 facing the intermediate gear 1075. Under the elastic force of the elastic component 1074, the fifth cam surface 10751 abuts against the sixth cam surface 10733, which is beneficial to enhancing the damping force of the rotation of the first shell 2 and the second shell 3 around the main axis, thereby improving the user's opening and closing feel.

[0159] It is worth mentioning that the arrangement of the magnetic component in the terminal device provided in the embodiment of the present application does not depend on the structure of the shaft mechanism provided in the above embodiment, and any shaft mechanism that can achieve the following functions is acceptable, namely:

[0160] The rotating shaft mechanism includes a main shaft, a first rotating assembly and a second rotating assembly, and the first rotating assembly and the second rotating assembly are respectively arranged on both sides of the axis of the main shaft. The first rotating assembly includes a first supporting arm and a first swinging arm, and the first supporting arm and the first swinging arm are rotatably connected to the main shaft, and the axes of rotation of the first supporting arm and the first swinging arm around the main shaft are parallel and do not overlap. In addition, the second rotating assembly includes a second supporting arm and a second swinging arm, and the second supporting arm and the second swinging arm are rotatably connected to the main shaft, and the axes of rotation of the second supporting arm and the second swinging arm around the main shaft are parallel and do not overlap.

[0161] In this way, the first housing can be rotatably connected to the main shaft through the first rotating assembly, and the direction in which the first housing and the first swing arm slide relative to each other is perpendicular to the axis of the main shaft. In addition, the second housing is rotatably connected to the main shaft through the second rotating assembly, and the direction in which the second housing and the second swing arm slide relative to each other is perpendicular to the axis of the main shaft. Thus, the magnetic assembly can be arranged between the relatively sliding housing and the swing arm, so that when the terminal device is in a closed state and a flattened state, the relative sliding of the housing and the corresponding swing arm can be restricted by the magnetic force of the magnetic member, so that the terminal device can be stably maintained in the closed state and the flattened state. Since in the terminal device, the holding force of the closed state and the holding force of the flattened state of the terminal device can be separately adjusted by separately adjusting the magnetic force of the magnetic member, it can enable the terminal device to be stably maintained in the closed state and the flattened state, and at the same time, it can also reduce the influence of the force on the opening and closing process, so it can improve the user experience.

[0162] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
