Specifically, the use of the words "in some embodiments," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner.
[0071] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.
[0072] In current technology, the pivot mechanism typically includes a main support, a main swing arm, a secondary swing arm, and a cam. The secondary swing arm works in conjunction with the cam as a damping component to achieve a damping feel. However, the structure of the secondary swing arm and the cam is complex, and the cam has high manufacturing requirements and is difficult to manufacture. In addition, the cam has limited space and a small hovering angle, making it difficult to achieve stable hovering; the cam is mounted on a cam support, and the cam, cam support, and secondary swing arm occupy a significant amount of internal space.
[0073] In view of this, embodiments of this application provide a pivot mechanism and a mobile terminal, which can solve the problems of complex structure and high manufacturing difficulty of damping components. The pivot mechanism provided in this application includes a base and at least one damping component disposed on the base. The base extends along a first direction. The damping component includes a swing arm, a pusher, a slider, and an elastic member. The swing arm is rotatably connected to the base; the pusher is connected to the swing arm; the slider is disposed on the base and slides in cooperation with the pusher; the elastic member elastically abuts against the slider; rotation of the swing arm can drive the pusher to move in a second direction, so as to push the slider to move in the first direction and deform the elastic member. The second direction intersects the first direction.
[0074] In the rotating shaft mechanism provided in this application embodiment, the damping component includes a swing arm, a pusher, a slider, and an elastic element. The rotational motion of the swing arm can be converted into the linear motion of the slider. The elastic element abuts against the slider and forms a damping force. The rotating shaft mechanism can provide damping force by rotating the swing arm, without the need for a cam to cooperate with the auxiliary swing arm to achieve the damping effect. It eliminates the need for a traditional cam. The rotating shaft mechanism provided in this application embodiment has the advantages of simple structure and low manufacturing difficulty. Furthermore, the pusher and slider slide in cooperation, and the slider does not need to rotate. This facilitates the setting of a surface on the slider that slides in cooperation with the pusher, which is beneficial for achieving a larger swing arm hovering angle range and improving the stability of the hovering state. In addition, in the rotating shaft mechanism, the swing arm can act as a rotating component and also cooperate with the pusher, slider, and elastic element to generate damping force. The rotating shaft mechanism provided in this application embodiment not only omits the traditional cam but also eliminates the auxiliary swing arm that rotates in cooperation with the cam, saving the internal space occupied by the auxiliary swing arm, further reducing manufacturing difficulty and cost, reducing the overall weight of the rotating shaft mechanism, and lowering assembly difficulty.
[0075] The mobile terminal provided in this application can be a foldable mobile terminal product with a flexible screen, such as a mobile phone, tablet computer, wearable device, in-vehicle device, augmented reality (AR) / virtual reality (VR) device, laptop computer, ultramobile personal computer (UMPC), netbook, or personal digital assistant (PDA). This application does not limit the specific type of mobile terminal. In this application, a mobile phone is used as an example for description.
[0076] Please see Figure 1 and Figure 2 , Figure 1 This paper shows a schematic diagram of the structure of a mobile terminal 1000 in its unfolded state according to an embodiment of this application, and... Figure 2 for Figure 1 A schematic diagram of the mobile terminal 1000 in its folded state. The mobile terminal 1000 includes a hinge mechanism 100, a screen 200, a first body 300, and a second body 400. The hinge mechanism 100 is connected between the first body 300 and the second body 400. The screen 200 is located on the surfaces of the first body 300, the second body 400, and the hinge mechanism 100, and is fixed to the first body 300 and the second body 400 respectively. The screen 200 is a flexible screen capable of bending. For example, the flexible screen may be an organic light-emitting diode (OLED) display, an active matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MLED) display, a micro light-emitting diode (MicroLED) display, a microorganic light-emitting diode (MicroLED) display, or a quantum dot light-emitting diode (QLED) display.
[0077] The mobile terminal 1000 can utilize the pivot mechanism 100 to rotate the first main body 300 and the second main body 400 relative to each other, thereby enabling the mobile terminal 1000 to fold and unfold, that is, the mobile terminal 1000 can switch between an unfolded state and a folded state. Figure 1The diagram shows the structure of the mobile terminal 1000 in its unfolded state. For example, the mobile terminal 1000 is in a flattened state, with the first main body 300 and the second main body 400 approximately at 180° (a slight deviation is also allowed, such as 165°, 177°, or 185°). The first main body 300 and the second main body 400 are located on the same plane, and the screen 200 is laid flat on the surfaces of the two main bodies and the pivot mechanism 100. Figure 2 The diagram shows the structure of the mobile terminal 1000 in a folded state. For example, in the folded state, the first main body 300 and the second main body 400 are approximately parallel to each other, and the screen 200 is folded within the space enclosed by the first main body 300, the second main body 400, and the hinge mechanism 100. The structure of the mobile terminal 1000 in the folded state is not limited to this; for example, the screen 200 may also be located outside the first main body 300, the second main body 400, and the hinge mechanism 100. When the mobile terminal 1000 is in a flattened state, the screen 200 is in a flattened form, enabling full-screen display; when the mobile terminal 1000 is in a folded state, the screen 200 is in a folded form, facilitating user carrying and storage.
[0078] An embodiment of the first aspect of this application provides a rotating shaft mechanism 100. Please refer to... Figure 3 , Figure 4 The rotating shaft mechanism 100 includes a base 10 and at least one damping component 20 disposed on the base 10. The base 10 extends along a first direction Y. The damping component 20 includes a swing arm 21, a pusher 22, a slider 23, and an elastic member 24. The swing arm 21 is rotatably connected to the base 10. The pusher 22 is connected to the swing arm 21. The slider 23 is disposed on the base 10 and slides with the pusher 22. The elastic member 24 elastically abuts against the slider 23. The rotation of the swing arm 21 can drive the pusher 22 to move in a second direction X. The pusher 22 can drive the slider 23 to move in the first direction Y and deform the elastic member 24. The second direction X intersects the first direction Y.
[0079] Please refer to Figures 1 to 4 The base 10 provides an installation foundation for the damping component 20. The base 10 extends along the first direction Y, that is, the length direction of the base 10 is the first direction Y. Figure 3 The diagram illustrates a partial structure of the base 10. The first direction Y can be the length or width direction of the mobile terminal 1000. At least one damping component 20 is provided on the base 10. When there are multiple damping components 20, the multiple damping components 20 are arranged along the length direction of the base 10.
[0080] The damping component 20 provides a damping force. When the mobile terminal 1000 is in a flattened state, the damping component 20 provides a certain damping force, which prevents the mobile terminal 1000 from being folded, thereby maintaining the relative position of the first main body 300 and the second main body 400. When the mobile terminal 1000 is in a folded state, the damping component 20 provides a certain damping force, which keeps the mobile terminal 1000 in a folded state, thereby maintaining the relative position of the first main body 300 and the second main body 400.
[0081] The swing arm 21 is rotatably connected to the base 10. The swing arm 21 rotates about an axis. The axis of rotation of the swing arm 21 can be parallel to the first direction Y or at an angle to the first direction Y.
[0082] Please refer to Figures 1 to 3 The swing arm 21 can be connected to the first body 300 or the second body 400. For example, in a damping assembly 20, at least two swing arms 21 can be provided. At least one swing arm 21 is connected to the first body 300, and at least another swing arm 21 is connected to the second body 400. By rotating at least two swing arms 21, the first body 300 and the second body 400 can be driven to rotate relative to each other, thereby realizing the unfolding or folding of the mobile terminal 1000.
[0083] The pusher 22 is connected to the swing arm 21. The pusher 22 can move in various ways in the second direction X. For example, the pusher 22 can translate along the second direction X, or the pusher 22 can rotate with the swing arm 21 and be displaced in the second direction X. The second direction X can intersect the first direction Y perpendicularly, or the second direction X can intersect the first direction Y at other angles.
[0084] The pusher 22 can be mounted on the base 10 and connected to the swing arm 21 in a transmission manner. The rotation of the swing arm 21 can drive the pusher 22 to move in the second direction X. Alternatively, the pusher 22 can be fixedly connected to the swing arm 21. When the swing arm 21 rotates, the swing arm 21 can drive the pusher 22 to rotate, and the pusher 22 moves relative to the base 10 in the second direction X.
[0085] The slider 23 and the pusher 22 are in sliding engagement, meaning that the end face of the pusher 22 and the end face of the slider 23 can slide relative to each other. When the pusher 22 moves in the second direction X, it can drive the slider 23 to move in the first direction Y. Optionally, the swing arm 21 and the slider 23 are located on opposite sides of the pusher 22 along the first direction Y, but this is not a limitation, as long as the pusher 22 can connect the swing arm 21 and the slider 23 simultaneously.
[0086] The elastic element 24 may include an elastic element such as a spring. The elastic element 24 elastically abuts against the sliding element 23 to apply a spring force to the sliding element 23. In some embodiments, the elastic element 24 abuts against the sliding element 23 along a first direction X. The elastic element 24 and the pushing element 22 are respectively disposed on opposite sides of the sliding element 23 along the first direction X. When the pushing element 22 drives the sliding element 23 to move away from the swing arm 21, the elastic element 24 will be compressed and deformed, and the sliding element 23 will be subjected to opposite forces applied by the pushing element 22 and the elastic element 24. When the pushing element 22 drives the sliding element 23 to move closer to the swing arm 21, the elastic element 24 will stretch and recover at least part of its deformation. In other embodiments, the elastic element 24 may also be disposed on the side of the sliding element 23 closer to the swing arm 21.
[0087] When the slider 23 moves, the elastic element 24 undergoes elastic deformation under force to generate a damping force. This damping force acts on the swing arm 21, allowing the user to feel the damping sensation. Furthermore, the elastic element 24 elastically supports the slider 23. When the swing arm 21 is not subjected to external force, the elastic element 24 can also keep the slider 23, the pusher 22, and the swing arm 21 stationary. Thus, the swing arm 21 can be suspended at a preset angle, allowing either the first main body 300 or the second main body 400 connected to the swing arm 21 to be suspended at the preset angle, i.e., the mobile terminal 1000 can be suspended. When the swing arm 21 is suspended, the angle between the first main body 300 and the second main body 400 remains fixed. For example, the angle between the first main body 300 and the second main body 400 can be 35°, 70°, 90°, 120°, 130°, 140°, 150°, etc., at which time the screen 200 is in a semi-open state.
[0088] Optionally, at least one of the base 10, swing arm 21, pusher 22, slider 23 and elastic member 24 may be a metal part, such as a steel part, so that the parts in the rotating shaft mechanism 100 have high structural strength; in other embodiments, at least one of the base 10, swing arm 21, pusher 22, slider 23 and elastic member 24 may also be made of other materials, such as aluminum, aluminum alloy, plastic, etc.
[0089] Please refer to Figure 3 , Figure 9 and Figure 10 In use, the swing arm 21 can rotate relative to the base 10 to switch between an unfolded position and a folded position, such as... Figure 3 As shown, the swing arm 21 is in the extended position, as... Figure 10 As shown, the swing arm 21 is close to the folded position. When the swing arm 21 rotates, it can drive the pusher 22 to move in the second direction X. The pusher 22 drives the slider 23 to move in the first direction Y and deforms the elastic member 24 to generate a damping force, so that the user can experience a damping feel.
[0090] The rotating shaft mechanism 100 provided in this application embodiment includes a base 10 and a damping assembly 20. The damping assembly 20 includes a swing arm 21, a pusher 22, a slider 23, and an elastic member 24. The swing arm 21 is rotatably connected to the base 10. The pusher 22 is connected to the swing arm 21 and slides with the slider 23. The elastic member 24 elastically abuts against the slider 23. The rotation of the swing arm 21 can drive the pusher 22 to move in the second direction X, thereby driving the slider 23 to move in the first direction Y, causing the elastic member 24 to deform and generate a damping force. The damping assembly 20 can convert the rotational motion of the swing arm 21 into the linear motion of the slider 23. The damping force can be provided by the rotation of the swing arm 21 without the need for a cam to cooperate with the auxiliary swing arm 21 to achieve the damping effect. There is no need to set a traditional cam. The rotating shaft mechanism 100 provided in this application embodiment has the advantages of simple structure and low manufacturing difficulty. Furthermore, the pusher 22 and the slider 23 slide together, and the slider 23 does not need to rotate. This makes it easy to set the surface shape on the slider 23 that slides together with the pusher 22, which is beneficial to achieving a larger hovering angle range of the swing arm 21 and can improve the stability of the hovering state.
[0091] Furthermore, in the rotating shaft mechanism 100, the swing arm 21 can function as both a rotating component (i.e., a main swing arm) and a component that works with the pusher 22, the slider 23, and the elastic element 24 to generate damping force. The rotating shaft mechanism 100 provided in this embodiment only needs to rely on the rotation of the swing arm 21 to provide damping force, which not only eliminates the traditional cam but also eliminates the auxiliary swing arm that works with the cam's rotation, saving the internal space occupied by the auxiliary swing arm and further reducing manufacturing difficulty and cost. It is understood that the rotating shaft mechanism 100 can also be provided with both a main swing arm and an auxiliary swing arm, and the swing arm 21 in the damping assembly 20 can be either a main swing arm or an auxiliary swing arm.
[0092] Please refer to Figures 3 to 8 In some embodiments, the outer periphery of the pusher 22 is provided with a first mating surface 222, and the first mating surface 222 includes a first hovering portion 2221 and a first inclined portion 2222. The outer periphery of the slider 23 is provided with a second mating surface 231 that slides with the first mating surface 222, and the second mating surface 231 includes a second hovering portion 2311 and a second inclined portion 2312. At least one of the first hovering portion 2221 and the second hovering portion 2311 is a plane parallel to the second direction X. When the first hovering portion 2221 and the second hovering portion 2311 are in contact, the slider 23 and the swing arm 21 can remain stationary relative to the base 10. The first inclined portion 2222 and the second inclined portion 2312 are both planes inclined relative to the second direction X. The first inclined portion 2222 and the second inclined portion 2312 are parallel to each other. When the first inclined portion 2222 and the second inclined portion 2312 slide with each other, the slider 23 can move in the first direction Y.
[0093] The outer periphery of the pushing member 22 is provided with a first mating surface 222, and the outer periphery of the sliding member 23 is provided with a second mating surface 231. The first mating surface 222 and the second mating surface 231 are slidably connected. When the pushing member 22 moves in the second direction X, it can push the second mating surface 231 through the first mating surface 222, thereby causing the sliding member 23 to move in the first direction Y. That is, the movement of the pushing member 22 in the second direction X is converted into the movement of the sliding member 23 in the first direction Y. The first mating surface 222 and the second mating surface 231 both include multiple planar segments, with simple surface shape and low manufacturing difficulty.
[0094] The first mating surface 222 includes a first hovering portion 2221 and a first inclined portion 2222, with the first inclined portion 2222 connected to one side of the first hovering portion 2221. The second mating surface 231 includes a second hovering portion 2311 and a second inclined portion 2312, with the second inclined portion 2312 connected to one side of the second hovering portion 2311. At least one of the first hovering portion 2221 and the second hovering portion 2311 is a plane parallel to the second direction X. When the first hovering portion 2221 and the second hovering portion 2311 are in contact and abut against each other, the elastic member 24 applies a certain elastic force to the sliding member 23. The damping force generated by the damping component 20 can keep the sliding member 23 and the swing arm 21 stationary relative to the base 10, that is, the swing arm 21 is in a hovering state and can hover at a preset angle. When the swing arm 21 rotates and the first hovering portion 2221 slides relative to the second hovering portion 2311, the damping component 20 continuously generates a damping force. In some embodiments, the first hovering portion 2221 and the second hovering portion 2311 are both parallel to the second direction X, the first tilting portion 2222 is disposed on one side of the first hovering portion 2221 along the second direction X, and the second tilting portion 2312 is disposed on the other side of the second hovering portion 2311 along the second direction X.
[0095] When in use, when the first hovering part 2221 and the second hovering part 2311 are in contact and abut against each other, the elastic member 24 maintains a certain deformation, and the sliding member 23 is simultaneously subjected to the squeezing force of the pushing member 22 and the elastic force of the elastic member 24. If the swing arm 21 is not subjected to external force, the swing arm 21 can be in a stable hovering state, that is, the swing arm 21 and the sliding member 23 can both remain stationary relative to the base 10.
[0096] When the swing arm 21 rotates, and the first inclined part 2222 and the second inclined part 2312 come into contact and abut against each other, the first inclined part 2222 can push the second inclined part 2312, causing the sliding member 23 to move along the first direction Y and deform the elastic member 24. The sliding member 23 is simultaneously subjected to the squeezing force of the pushing member 22 and the elastic force of the elastic member 24, and the damping assembly 20 can generate damping force.
[0097] In this embodiment, during the rotation of the swing arm 21 from the unfolded state to the hovering state, the first inclined portion 2222 and the second inclined portion 2312 are in sliding engagement. In other embodiments, the first inclined portion 2222 and the second inclined portion 2312 may also be in sliding engagement during the rotation of the swing arm 21 from the hovering state to the folded state; or, there may be two first inclined portions 2222, which are respectively located on opposite sides of the first hovering portion 2221 in the second direction X, and two second inclined portions 2312, which are respectively located on opposite sides of the second hovering portion 2311 in the second direction X.
[0098] By adopting the above technical solution, the pusher 22 and the slider 23 achieve sliding engagement through two mating surfaces. The lengths of the first hovering part 2221 and the second hovering part 2311 can be set according to requirements to facilitate setting a larger hovering angle range. Since at least one of the first hovering part 2221 and the second hovering part 2311 is a flat plane, it is beneficial to achieve stable hovering. The first tilting part 2222 and the second tilting part 2312 slide together, and the pusher 22 can drive the slider 23 to move and deform the elastic member 24 to generate damping force. In some existing situations, the space occupied by the cam is limited, the hovering angle range that the cam can provide is small, the hovering is unstable, and the manufacturing of the cam is difficult. In the solution provided by the embodiments of this application, the first hovering part 2221 and the second hovering part 2311, the first tilting part 2222 and the second tilting part 2312 can all be planes, and the damping component 20 does not need to be provided with a cam with a curved surface, which reduces the manufacturing difficulty of the damping component 20. The sliding member 23 moves by translation rather than rotation, which is beneficial to the arrangement of the movement space of the sliding member 23 and the realization of a larger hovering angle range. When the first hovering part 2221 and the second hovering part 2311 are in contact, the swing arm 21 can maintain hovering, which improves the stability of the mobile terminal's hovering state.
[0099] In some embodiments, the first hovering portion 2221 and the second hovering portion 2311 are both planes parallel to the second direction X.
[0100] The lengths of the first hovering part 2221 and the second hovering part 2311 can be equal or unequal, both allowing for sliding engagement between them. When the rotation angle of the swing arm 21 is within a preset hovering angle range, the first hovering part 2221 and the second hovering part 2311 abut against each other, enabling the swing arm 21 to hover stably. This application does not limit the preset hovering angle range; it can be obtained by adjusting the damping component 20 according to product specifications. For example, a stable hovering can be achieved when the angle between the first body 300 and the second body 400 is between 70° and 140°, and when the swing arm 21 rotates from its folded state, a stable hovering can be achieved when the rotation angle of the swing arm 21 is between 35° and 70°.
[0101] By adopting the above technical solution, the first hovering part 2221 and the second hovering part 2311 are in surface contact, which has good stability and improves the stability of the hovering state.
[0102] In other embodiments, one of the first hovering part 2221 and the second hovering part 2311 can be set as a plane and the other as an endpoint. When the endpoint slides along the plane, the hovering arm 21 can also be hovered.
[0103] Please refer to Figure 3 , Figures 6 to 10 In some embodiments, the first mating surface 222 further includes a third inclined portion 2223, and the first inclined portion 2222, the first hovering portion 2221, and the third inclined portion 2223 are connected in sequence; the second mating surface 231 further includes a fourth inclined portion 2313, and the fourth inclined portion 2313, the second hovering portion 2311, and the second inclined portion 2312 are connected in sequence. Both the third inclined portion 2223 and the fourth inclined portion 2313 are inclined surfaces relative to the second direction X, and are arranged parallel to each other. When the third inclined portion 2223 and the fourth inclined portion 2313 are in sliding engagement, the sliding member 23 can move in the first direction Y and deform the elastic member 24.
[0104] like Figure 3 and Figure 7 As shown, the first mating surface 222 includes a first inclined portion 2222, a first hovering portion 2221, and a third inclined portion 2223 arranged sequentially along the second direction X. Along the direction toward the slider 23, the third inclined portion 2223 and the first inclined portion 2222 are inclined toward the direction close to the center line of the pusher 22. That is to say, along the direction toward the slider 23 (which is also the direction away from the swing arm 21), the third inclined portion 2223 and the first inclined portion 2222 gradually approach each other. The inclination directions of the third inclined portion 2223 and the first inclined portion 2222 are opposite. The first mating surface 222 has a wedge-shaped surface structure.
[0105] The first inclined portion 2222 forms an angle α with the second direction X, the third inclined portion 2223 forms an angle β with the second direction X, and the first hovering portion 2221 is parallel to the second direction X. The included angles α and β can be set according to requirements; they can be equal or unequal. The larger the included angles α and β, the greater the friction. The length L of the first hovering portion 2221 can also be set according to requirements; the longer the first hovering portion 2221, the wider the hovering angle range of the swing arm 21. Furthermore, the lengths of the first inclined portion 2222 and the third inclined portion 2223 can also be set according to requirements.
[0106] like Figure 3 and Figure 8As shown, the second mating surface 231 includes a fourth inclined portion 2313, a second hovering portion 2311, and a second inclined portion 2312 arranged sequentially along the second direction X. The second hovering portion 2311 is parallel to the second direction X, and the second inclined portion 2312 and the fourth inclined portion 2313 are both inclined to the second direction X. Along the direction toward the pusher (which is also the direction closer to the swing arm 21), the second inclined portion 2312 and the fourth inclined portion 2313 are inclined toward the centerline of the slider 23. That is to say, along the direction closer to the swing arm 21, the second inclined portion 2312 and the fourth inclined portion 2313 gradually approach each other, and the second mating surface 231 has a roughly wedge-shaped structure.
[0107] The upper and lower surfaces of the slider 23 in the third direction Z are both planes, and the second mating surface 231 on the slider 23 is the side of the slider 23 facing the pusher 22. The third direction Z can be the thickness direction of the mobile terminal.
[0108] Please refer to Figure 3 , Figures 7 to 10 The swing arm 21 can rotate relative to the base 10 about an axis. For example... Figure 3 As shown, the swing arm 21 is in the extended state, and the first inclined portion 2222 on the pusher 22 is in contact with the second inclined portion 2312 on the slider 23. When the swing arm 21 starts to rotate from the extended state, the swing arm 21 drives the pusher 22 to move in the second direction X (the direction shown in the figure is the pusher 22 moving to the left). The first inclined portion 2222 and the second inclined portion 2312 slide in cooperation, and the slider 23 can move along the first direction Y in a direction away from the swing arm 21 and squeeze the elastic member 24. The elastic member 24 is compressed. At this time, the damping assembly 20 is in the climbing state, and the damping assembly 20 generates damping force.
[0109] like Figures 3 to 9 As shown, when the rotation angle of the swing arm 21 is within the preset hovering angle range, the first hovering part 2221 and the second hovering part 2311 are in contact and abut against each other. The sliding member 23 is simultaneously subjected to the squeezing force of the pushing member 22 and the elastic force of the elastic member 24. The squeezing force and the elastic force are in opposite directions, achieving balance. If the swing arm 21 is not subjected to external force, the swing arm 21 can remain in a hovering state, that is, the swing arm 21 can hover in any intermediate state. The mobile terminal can maintain a certain unfolding angle, and the swing arm 21, the pushing member 22, and the sliding member 23 can remain stationary relative to the base 10. It can be understood that the longer the length of the first hovering part 2221 and the second hovering part 2311 that cooperates, the larger the hovering angle range of the swing arm 21. Thus, the rotating shaft mechanism 100 can obtain a larger hovering angle range. Within the hovering angle range, the swing arm 21 can hover at any angle.
[0110] like Figure 2 , Figure 10As shown, the swing arm 21 continues to rotate relative to the base 10. The swing arm 21 drives the pusher 22 to move in the second direction X (the direction shown is the pusher 22 moving to the left). The third inclined portion 2223 and the fourth inclined portion 2313 are in contact. The slider 23 moves towards the swing arm 21. The elastic member 24 gradually extends. The damping assembly 20 is in a downhill state. The elastic member 24 applies a closing force to the swing arm 21, which helps the swing arm 21 to rotate smoothly to the folded state, so that the first body 300 and the second body 400 are closed. Optionally, when the included angle between the first body 300 and the second body 400 is small, the first body 300 and the second body 400 can be closed without external force under the action of the closing force.
[0111] It is understandable that during the process of the swing arm 21 rotating from the folded state to the unfolded state, the third inclined part 2223 first slides relative to the fourth inclined part 2313, at which time the damping component 20 is in the climbing state. Then the first hovering part 2221 slides with the second hovering part 2311, and the damping component 20 can remain in the hovering state. Then the first inclined part 2222 slides relative to the second inclined part 2312, at which time the damping component 20 is in the descending state.
[0112] In addition, when the swing arm 21 is in the unfolded or folded state, the damping force generated by the damping component 20 can keep the swing arm 21 stably in the unfolded or folded state.
[0113] When the first hovering part 2221 and the second hovering part 2311 are in contact, the swing arm 21 can be hovered at any angle. It can be understood that since the sliding member 23 is simultaneously subjected to the forces applied by the pushing member 22 and the elastic member 24, the swing arm 21 can be hovered when the two forces reach a balance. Therefore, the range of angles at which the swing arm 21 can be hovered is not limited to the range of angles when the first hovering part 2221 and the second hovering part 2311 are in contact. For example, the swing arm 21 can also be hovered when the first tilting part 2222 and the second tilting part 2312 are in sliding contact, or when the third tilting part 2223 and the fourth tilting part 2313 are in sliding contact.
[0114] By adopting the above technical solution, the first mating surface 222 and the second mating surface 231 slide together, enabling the damping component 20 to be in the climbing state, the hovering state, and the downhill state successively, providing damping force to the swing arm 21 and enabling the swing arm 21 to be in a stable hovering state within the hovering angle range, so that the user can obtain a better damping feel; the first hovering part 2221 and the second hovering part 2311 can be set to a longer length, so that the hovering angle range of the swing arm 21 is larger; the rotating shaft mechanism 100 provides a new cam mating method, unfolding the three surfaces on the traditional cam into one surface, reducing the manufacturing difficulty and enabling more stable hovering at a larger angle.
[0115] In some embodiments, when the swing arm 21 is in the unfolded state, its upper surface is parallel to the upper surface of the base 10. When the swing arm 21 is rotated to the folded state, its upper surface can be perpendicular to the upper surface of the base 10. Thus, the swing arm 21 can rotate 90°. When at least two sets of damping components 20 are provided, and the at least two sets of damping components 20 are respectively provided on opposite sides of the base 10, the two swing arms 21 can each rotate 90° to flatten or fold the first body 300 and the second body 400.
[0116] Please refer to Figure 3 , Figure 5 and Figure 6 In some embodiments, the swing arm 21 is provided with an arc-shaped first rack portion 2111; the pusher 22 is movably disposed on the base 10 along the second direction X, and the pusher 22 is provided with a second rack portion 221 that meshes with the first rack portion 2111.
[0117] The first rack portion 2111, also known as the first gear structure, is located on the outer periphery of the swing arm 21 and is arranged around the rotation axis of the swing arm 21. In some embodiments, the swing arm 21 includes a rotating portion 211 and a main body connecting portion 212. The rotating portion 211 is rotatably connected to the base 10, and the main body connecting portion 212 is located on the side of the rotating portion 211 away from the base 10, that is, the main body connecting portion 212 and the rotating portion 211 are sequentially connected along the second direction X. The rotating portion 211 and the main body connecting portion 212 can be integrally formed or separate structures; the rotating portion 211 can be semi-circular to reduce the size of the rotating portion 211 in the third direction Z, and the rotating portion 211 can also be fan-shaped, circular, or other shapes; the main body connecting portion 212 is used to connect the first main body 300 or the second main body 400 so that the swing arm 21 drives the first main body 300 or the second main body 400 to rotate, and the structure of the main body connecting portion 212 can be various, such as strip-shaped, plate-shaped, etc. The first rack portion 2111 is arc-shaped, and the curvature of the first rack portion 2111 can be set according to requirements.
[0118] The pusher 22 is movably mounted on the base 10. Specifically, the pusher 22 is movably mounted on the base 10 along the second direction X. The pusher 22 has a second rack portion 221 that meshes with the first rack portion 2111. The second rack portion 221 extends along the second direction X. Thus, the first rack portion 2111 and the second rack portion 221 are connected in a transmission manner. The rotation of the swing arm 21 can drive the pusher 22 to reciprocate along the second direction X, that is, the rotational motion of the swing arm 21 can be converted into the horizontal movement of the pusher 22. It should be noted that the tooth pitch, number of teeth, tooth thickness, and module of the first rack portion 2111 and the second rack portion 221 can all be determined according to the product specifications.
[0119] The pusher 22 also has a first mating surface 222. It can be understood that, for ease of component layout, the second rack portion 221 can be located on one side of the pusher 22 along the first direction Y, and the first mating surface 222 is located on the other side of the pusher 22 along the first direction Y. The pusher 22 functions as a cam rack. It can be understood that the height direction of the meshing teeth on the second rack portion 221 is located in the third direction Z, so that the second rack portion 221 meshes with the first rack portion 2111. The third direction Z intersects both the first direction Y and the second direction X. In some embodiments, the third direction Z is the thickness direction of the mobile terminal, and the third direction Z, the first direction Y, and the second direction X intersect each other perpendicularly.
[0120] By adopting the above technical solution, the swing arm 21 and the pusher 22 are separately arranged and connected by the first rack portion 2111 and the second rack portion 221 to convert the rotational motion of the swing arm 21 into the horizontal movement of the pusher 22. The structure of the swing arm 21 and the pusher 22 is simple, the transmission method is simple and reliable, and the swing arm 21 and the pusher 22 are easy to manufacture.
[0121] In some embodiments, the arc of the first rack portion 2111 is 90° to 180°.
[0122] The center of arc of the first rack portion 2111 may be located on the rotation axis of the rocker arm 21. The first rack portion 2111 is located on the side of the rocker arm 21 facing the pusher 22, so as to facilitate the connection of the first rack portion 2111 to the pusher 22. The arc of the first rack portion 2111 is 90° to 180°, for example, the arc of the first rack portion 2111 may be 90°, 100°, 120°, 130°, 140°, 150°, 160°, 170°, 180°, etc. In some embodiments, when the arc of the first rack portion 2111 is 90°, the rotating portion 211 may be a quarter-circular gear; when the arc of the first rack portion 2111 is 180°, the rotating portion 211 may be a semi-circular gear. It is understandable that the rotating part 211 can also be other structures, as long as it can achieve the goal of setting the arc range of the first rack part 2111 to 90°~180°.
[0123] By adopting the above technical solution, the curvature of the first rack portion 2111 can be flexibly set so that the first rack portion 2111 and the second rack portion 221 can maintain meshing and transmission connection. The curvature of the first rack portion 2111 does not need to be greater than 180°, so as to save the cost of the swing arm 21 and reduce the thickness of the swing arm 21 in the third direction Z.
[0124] In some embodiments, the arc of the first rack portion 2111 is 90° to 100°. The first rack portion 2111 is located on the side of the rocker arm 21 near the middle of the base 10, such as... Figure 3As shown, when the rocker arm 21 is in a flattened state, one end of the first rack portion 2111 meshes with the second rack portion 221; as Figure 10 As shown, when the swing arm 21 is in the folded state, the other end of the first rack portion 2111 meshes with the second rack portion 221, and the maximum rotation angle of the swing arm 21 can be 90°. The curvature of the first rack portion 2111 can adapt to the rotation angle of the swing arm 21.
[0125] By adopting the above technical solution, the arc of the first rack part 2111 is 90° to 100°, which can not only meet the rotation requirements of the swing arm 21, but also reduce the cost of parts and manufacturing difficulty.
[0126] Please refer to Figure 3 , Figure 6 In some embodiments, the swing arm 21 includes a rotating part 211 and a main body connecting part 212. The rotating part 211 is rotatably connected to the base 10, and the main body connecting part 212 is located on the side of the rotating part 211 away from the base 10. The first rack part 2111 is located on the edge of the rotating part 211. The pusher 22 has a second rack part 221 at one end near the swing arm 21, and the side of the other end of the pusher 22 is a first mating surface 222.
[0127] The first rack portion 2111 is located at the edge of the rotating portion 211 and can rotate around the rotation axis of the swing arm 21. The pusher 22 is generally block-shaped, and the tooth structure of the second rack portion 221 is arranged along the third direction Z. The second rack portion 221 is connected to the first rack portion 2111 in the third direction Z. The pusher 22 is located between the swing arm 21 and the slider 23, and simultaneously functions as a rack and a cam. In this way, the pusher 22 can be driven to both the swing arm 21 and the slider 23. The damping assembly 20 has a simple structure and occupies less space.
[0128] Please refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 In some embodiments, the first mating surface 222 and the second mating surface 231 are arranged in a centrally symmetrical manner.
[0129] The pusher 22 is slidably disposed on the base 10 along the second direction X, and the slider 23 is slidably disposed on the base 10 along the first direction Y. Both the pusher 22 and the slider 23 are block-shaped and do not need to be cam-shaped. The first mating surface 222 and the second mating surface 231 each include multiple planar segments. That is, the first mating surface 222 includes a first inclined portion 2222, a first hovering portion 2221 and a third inclined portion 2223 connected in sequence, and the second mating surface 231 includes a fourth inclined portion 2313, a second hovering portion 2311 and a second inclined portion 2312 connected in sequence. The first mating surface 222 and the second mating surface 231 are centrally symmetrically arranged, that is, the first inclined portion 2222 and the second inclined portion 2312 are symmetrically arranged, the first hovering portion 2221 and the second hovering portion 2311 are symmetrically arranged, and the third inclined portion 2223 and the fourth inclined portion 2313 are symmetrically arranged.
[0130] By adopting the above technical solution, the first mating surface 222 and the second mating surface 231 are set as symmetrical surfaces, eliminating the need to set a cam surface. The pusher 22 and the slider 23 have simple structures, high manufacturing precision, are easy to use, and operate stably.
[0131] like Figures 3 to 10 As shown, the swing arm 21 is connected to the pusher 22 via a transmission connection; in other embodiments, the swing arm 21 may also be fixedly connected to the pusher 22. Please refer to... Figure 11 , Figure 12 In some embodiments, the pusher 22 is fixedly connected to one side of the swing arm 21, the pusher 22 is arc-shaped, and the first mating surface 222 is the side of the pusher 22 facing the slider 23.
[0132] The base 10 includes a base 11 and a support member 12 protruding from the base 11. The swing arm 21 is rotatably connected to the support member 12, and the pusher 22 is fixedly connected to the side of the swing arm 21 facing the base 11. When the swing arm 21 rotates, the pusher 22 rotates synchronously with the swing arm 21.
[0133] The pusher 22 is arc-shaped, and the curvature of the pusher 22 can be set according to the rotation angle of the swing arm 21. When the pusher 22 rotates, it rotates with the swing arm 21 and moves relative to the base 10 in the second direction X. The side of the pusher 22 facing the slider 23 is the first mating surface 222, which can slide and engage with the second mating surface 231 of the slider 23, so that the slider 23 can move in the first direction Y.
[0134] In some embodiments, the first mating surface 222 includes multiple planar segments, and the second mating surface 231 also includes multiple planar segments. The pusher 22 and the slider 23 respectively have multiple planar segments disposed on the same side, eliminating the need for a cam structure. Optionally, the first mating surface 222 includes a first inclined portion 2222, a first hovering portion 2221, and a third inclined portion 2223 arranged sequentially. The first inclined portion 2222, the first hovering portion 2221, and the third inclined portion 2223 are arranged sequentially along the second direction X and along the arcuate shape of the pusher 22. Please refer to... Figure 8 The second mating surface 231 includes a fourth inclined portion 2313, a second hovering portion 2311, and a second inclined portion 2312 arranged sequentially. The third inclined portion 2223 is slidably engaged with the fourth inclined portion 2313, the first hovering portion 2221 is slidably engaged with the second hovering portion 2311, and the first inclined portion 2222 is slidably engaged with the second inclined portion 2312. Thus, when the swing arm 21 rotates, the damping assembly 20 can sequentially pass through the climbing section, the hovering section, and the descending section to achieve the hovering of the pivot mechanism 100 and provide a damping feel.
[0135] By adopting the above technical solution, the pusher 22 is fixedly connected to the swing arm 21. The pusher 22 is arc-shaped. When the swing arm 21 rotates, the pusher 22 can move relative to the base 10 in the second direction X. The side of the pusher 22 facing the slider 23 is the first mating surface 222. The first mating surface 222 and the second mating surface 231 of the slider 23 are slidably mated. Thus, the pusher 22 can drive the slider 23 to slide. The rotating shaft mechanism 100 provided in this application embodiment does not need to set the pusher 22 and the slider 23 as a cam structure. The structure of the pusher 22 and the slider 23 is simple and the manufacturing difficulty is low.
[0136] In some embodiments, the swing arm 21 and the pusher 22 are integrally connected. The swing arm 21 and the pusher 22 are made of the same material and manufactured using a one-piece molding process. Thus, the swing arm 21 and the pusher 22 form a single integrated structure with high connection strength, further simplifying the structure and reducing manufacturing difficulty and cost.
[0137] Please continue to refer to Figure 11 and Figure 12 In some embodiments, the swing arm 21 includes a rotating part 211 and a main body connecting part 212. The rotating part 211 is rotatably connected to the base 10, and the main body connecting part 212 is located on the side of the rotating part 211 away from the base 10. The rotating part 211 is fixedly engaged with the pusher 22.
[0138] Optionally, the rotating part 211 is semi-circular and can rotate relative to the base 10 about an axis. The axis of rotation of the rotating part 211 can be parallel to the first direction Y, but is not limited thereto. The main body connecting part 212 is used to connect the first main body 300 or the second main body 400, so that the rotation of the swing arm 21 can drive the first main body 300 or the second main body 400 to rotate, so as to realize the folding or unfolding of the mobile terminal 1000. The peripheral edges of the rotating part 211 and the pushing member 22 are respectively provided with toothed parts, so that the rotating part 211 and the pushing member 22 are fixedly engaged by the toothed parts. In this way, the pushing member 22 can rotate with the rotating part 211, that is, the pushing member 22 moves relative to the base 10 along the second direction X, and at the same time moves relative to the base 10 along the third direction Z.
[0139] By adopting the above technical solution, the swing arm 21 and the pusher 22 are separate structures and can be manufactured separately, which provides a high degree of flexibility in manufacturing.
[0140] In other embodiments, the swing arm 21 and the pusher 22 can also be driven by other means, so that the pusher 22 can rotate with the swing arm 21. For example, the swing arm 21 and the pusher 22 are mounted on the same rotating shaft, or driven by a structure such as gears.
[0141] In some embodiments, the radius of the pusher 22 is 90° to 180°.
[0142] The center of arc of the pusher 22 may be located on the rotation axis of the swing arm 21. In other embodiments, the center of arc of the pusher 22 may not be concentric with the rotation center of the swing arm 21. The pusher 22 is located on the side of the swing arm 21 facing the base 10 to facilitate connection between the pusher 22 and the base 10. The arc of the pusher 22 is 90° to 180°, for example, the arc of the pusher 22 may be 90°, 100°, 120°, 130°, 140°, 150°, 160°, 170°, 180°, etc.
[0143] By adopting the above technical solution, the curvature of the pusher 22 can be flexibly set, and the curvature of the pusher 22 does not need to be greater than 180°, so as to save the cost of the damping component 20.
[0144] In some embodiments, the radius of curvature of the pusher 22 is 90° to 100°. The maximum rotation angle of the swing arm 21 can be 90°. The radius of curvature of the pusher 22 meets the above range, which can adapt to the rotation angle of the swing arm 21 and has a small cost and small space occupation.
[0145] Please refer to Figures 3 to 12In some embodiments, the length of the first hovering portion 2221 is greater than the length of the first tilting portion 2222 and / or the third tilting portion 2223. By providing a longer length for the first hovering portion 2221, the hovering angle range of the damping assembly 20 can be increased. It is understood that the length relationship of the first hovering portion 2221, the first tilting portion 2222, and the third tilting portion 2223 can also be set to other types.
[0146] Please refer to Figures 1 to 12 In some embodiments, the base 10 includes a base 11 and a support member 12 protruding from the base 11, a swing arm 21 is rotatably connected to the support member 12, and a sliding member 23 and an elastic member 24 are disposed on the base 11.
[0147] The base 11 can be the shaft cover of the mobile terminal 1000, and the base 11 extends along the first direction Y; the support member 12 protrudes from the base 11 along the third direction Z, and the swing arm 21 is rotatably connected to the support member 12, and the swing arm 21 can rotate around a fixed center on the support member 12. Optionally, the support member 12 is provided with a rotating shaft, and the swing arm 21 is rotatably connected to the support member 12 through the rotating shaft.
[0148] The support member 12 and the base 11 can be an integral structure or separate structures that are fixedly connected. Both the support member 12 and the base 11 can be metal parts, such as steel parts, so that the base 10 has high structural strength. In other embodiments, the support member 12 and / or the base 11 can also be made of other materials, such as copper, aluminum, aluminum alloy or plastic.
[0149] The pusher 22 is located on the side of the swing arm 21 facing the slider 23. The pusher 22 can be located on the base 11 and connected to the swing arm 21 in a transmission manner, or the pusher 22 can be fixedly connected to the swing arm 21. The slider 23 and the elastic member 24 are located on the base 11, and the slider 23 can reciprocate on the base 11.
[0150] By adopting the above technical solution, the base 11 can be equipped with the sliding member 23 and the elastic member 24, and the support member 12 can be equipped with the swing arm 21. The swing arm 21 can rotate above the base 11 so as to drive the pusher 22 and the sliding member 23 to move.
[0151] In other embodiments, the swing arm 21 may also be rotatably connected to the base 10 via other structures. The base 10 is provided with a rotation groove, and one end of the swing arm 21 is rotatably connected to the rotation groove.
[0152] In some embodiments, such as Figure 3As shown, the pusher 22 is movably disposed on the base 11. The pusher 22 can fit against the support 12. The elastic member 24 applies a spring force toward the pusher 22 to the sliding member 23. In this way, the support 12 can guide and limit the movement of the pusher 22, which is beneficial to improving the movement accuracy of the pusher 22 along the second direction X.
[0153] In some embodiments, the base 11 is provided with a first sliding groove 111, and the slider 23 is slidably disposed in the first sliding groove 111.
[0154] Optionally, the slider 23 is block-shaped, and its two sides along the second direction X are slidably connected to the groove walls of the first sliding groove 111, which provides limiting and guiding functions for the sliding of the slider 23. The structure of the first sliding groove 111 is not limited to this, as long as the slider 23 can move within the first sliding groove 111. In some embodiments, the groove walls of the first sliding groove 111 are spaced apart from the support member 12, and the pusher 22 can move between the groove walls of the first sliding groove 111 and the support member 12.
[0155] By adopting the above technical solution, the first sliding groove 111 can provide limiting and guiding functions for the sliding of the sliding member 23, thereby improving the motion accuracy of the sliding member 23.
[0156] In other embodiments, the first sliding groove 111 may be omitted, and a guide bar or slide rail extending along the first direction Y is provided on the base 11. The sliding member 23 is slidably connected to the guide bar or slide rail, and the guide bar or slide rail can also limit and guide the movement of the sliding member 23.
[0157] In some embodiments, the elastic member 24 elastically abuts against the sliding member 23 along the first direction Y.
[0158] The elastic element 24 can be a spring, and its deformation direction is also the first direction Y. When the slider 23 moves along the first direction Y, the elastic element 24 will deform. In some embodiments, the elastic element 24 abuts against the side of the slider 23 away from the swing arm 21. Specifically, when the slider 23 moves away from the swing arm 21, the elastic element 24 will be compressed and deformed; when the slider 23 moves closer to the swing arm 21, the elastic element 24 will recover some of its elastic deformation. In other embodiments, the elastic element 24 may also abut against the side of the slider 23 facing the swing arm 21.
[0159] By adopting the above technical solution, the elastic force applied by the elastic element 24 to the sliding element 23 is a positive force, and the sliding element 23 moves along the first direction Y without easily deflecting, and the movement accuracy of the sliding element 23 is high.
[0160] In some embodiments, the end of the slider 23 away from the swing arm 21 is provided with a guide post 232 extending along the first direction Y, one end of the elastic member 24 is sleeved on the guide post 232, and the other end is connected to the base 10, and the deformation direction of the elastic member 24 is parallel to the first direction Y.
[0161] The number of guide posts 232 and elastic elements 24 can be multiple. The elastic elements 24 can be springs or other elements with elastic deformation capabilities such as elastic foam. One end of each elastic element 24 is sleeved on the corresponding guide post 232 and elastically abuts against the slider 23, and the other end is connected to the base 11. The deformation direction of the elastic element 24 is parallel to the first direction Y, so that the elastic force applied by the elastic element 24 to the slider 23 is parallel to the first direction Y, making it difficult for the slider 23 to deflect relative to the first direction Y.
[0162] Optionally, the end of the elastic element 24 facing away from the sliding element 23 can abut against the groove wall of the first sliding groove 111. It can be understood that the end of the elastic element 24 facing away from the sliding element 23 only needs to be fixed on the base 11.
[0163] By adopting the above technical solution, the guide post 232 can install the elastic element 24 and guide the elastic element 24. The elastic force applied by the elastic element 24 to the sliding element 23 is a positive force, and the installation method of the elastic element 24 is relatively simple.
[0164] In another embodiment, the elastic element 24 is a spring, and the elastic element 24 may also be provided at one end of the slider 23 near the swing arm 21.
[0165] Please refer to Figures 3 to 12In some embodiments, the rotating shaft mechanism 100 includes a base 10 and at least one damping assembly 20 disposed on the base 10. The base 10 extends along a first direction Y. The damping assembly 20 includes a swing arm 21, a pusher 22, a slider 23, and an elastic member 24. The pusher 22 is connected to the swing arm 21 and has a first mating surface 222. The slider 23 is disposed on the base 10 and has a second mating surface 231 that slides in cooperation with the first mating surface 222. The elastic member 24 elastically abuts against the slider 23 and provides damping force. Rotation of the swing arm 21 can drive the pusher 22 to move in the second direction X, thereby pushing the slider 23 to slide along the first direction Y and causing the elastic member 24 to undergo elastic deformation to generate damping force. The first mating surface 222 includes a first inclined portion 2222, a first hovering portion 2221, and a third inclined portion 2223 connected sequentially in the second direction X; the second mating surface 231 includes a fourth inclined portion 2313, a second hovering portion 2311, and a second inclined portion 2312 connected sequentially in the second direction X. The first hovering portion 2221 and the second hovering portion 2311 are both parallel to the second direction X. The third inclined portion 2223 and the first inclined portion 2222 are connected to the first hovering portion 2221 at obtuse angles. The third inclined portion 2223 and the first inclined portion 2222 gradually move closer to each other in the direction closer to the first hovering portion 2221; the second hovering portion 2311 is in sliding engagement with the first hovering portion 2221, the second inclined portion 2312 is in sliding engagement with the first inclined portion 2222, and the fourth inclined portion 2313 is in sliding engagement with the third inclined portion 2223. The swing arm 21 rotates forward or backward relative to the base 10 around an axis, enabling the swing arm 21 to switch between the folded position and the unfolded position. The damping component 20 enables the pivot mechanism 100 to be suspended and provides a damping feel.
[0166] In the rotating shaft mechanism 100 provided in this application embodiment, the swing arm 21 can generate damping force by rotating. The rotating shaft mechanism 100 can obtain a large hovering angle range without the need to set a traditional cam. The rotating shaft mechanism 100 provided in this application embodiment has the advantages of simple structure and low manufacturing difficulty.
[0167] Please refer to Figures 1 to 12 The second aspect of this application provides a mobile terminal 1000, including a first body 300, a second body 400 and a screen 200, the screen 200 covering the first body 300 and the second body 400, and the mobile terminal 1000 also includes a pivot mechanism 100 provided in any embodiment of the first aspect, the first body 300 and the second body 400 being opened or closed by the pivot mechanism 100.
[0168] The mobile terminal 1000 provided in this application embodiment includes the pivot mechanism 100 provided in the first aspect, which also solves the problems of complex structure and high manufacturing difficulty of the existing damping component 20.
[0169] In some embodiments, the damping assembly 20 is provided with at least two sets, with the swing arm 21 in at least one set of the damping assembly 20 connected to the first body 300, and the swing arm 21 in at least another set of the damping assembly 20 connected to the second body 400.
[0170] At least two sets of damping components 20 are respectively disposed on both sides of the base 10 along its width direction and are symmetrically arranged so that the at least two sets of damping components 20 can drive the first body 300 and the second body 400 to move relative to each other.
[0171] The number of damping components 20 can be two or more. In this case, multiple sets of damping components 20 are provided on both sides of the base 10 along its width direction, and the multiple sets of damping components 20 on each side are distributed along the length direction of the base 10. This application does not limit the number of damping components 20, and the specific number can be set according to product requirements.
[0172] Thus, at least two sets of damping components 20 can drive the first main body 300 and the second main body 400 to rotate, thereby enabling the mobile terminal 1000 to open or close, that is, enabling the screen 200 to open or fold.
[0173] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
