[0010] In one possible implementation, the torque increasing assembly includes a torque slider and an elastic member, the torque slider is slidably engaged with the base, the torque slider is engaged with the self-locking cam, and both ends of the elastic member abut against the torque slider.

[0013] In one possible implementation, the outer peripheral surface of the self-locking cam includes a torque-increasing section and a constant torque section. When the swing arm rotates and the torque-increasing section abuts against the torque slider, the torque-increasing section is suitable for pushing the torque slider to slide.

[0039] As shown in the background technology, with the continuous development of electronic products, foldable electronic devices are becoming more and more popular. In the existing foldable display screen, a damping device such as a damping sheet is arranged in the rotating shaft to provide a damping force to achieve a hovering effect during the folding or unfolding of the foldable display screen. The damping force provided by the damping device in some solutions is relatively small, resulting in a poor hovering effect.

[0040] In view of the above technical problems, the embodiments of the present application provide a hinge mechanism and a smart terminal. The hinge mechanism includes a base, a swing arm and a torque-increasing component. The swing arm is used to connect with the support on the folding screen. The swing arm is rotatably connected to both sides of the base. When the folding screen is folded and unfolded, the swing arm is driven to rotate relative to the base. The torque-increasing component is arranged on the base. A self-locking cam is arranged at one end of the swing arm connected to the base. When the swing arm rotates relative to the base, the self-locking cam on the swing arm at least partially abuts against the torque-increasing component. When the folding screen is folded or unfolded, the swing arm is driven to rotate relative to the base. The swing arm drives the self-locking cam to rotate so that the self-locking cam abuts against at least part of the torque-increasing component. The torque-increasing component applies pressure to the self-locking cam, so that a certain friction force is generated between the torque-increasing component and the self-locking cam, thereby increasing the torque resistance of the swing arm, hindering the rotation of the swing arm, and helping to enhance the hovering effect of the folding screen.

[0041] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings:

[0042] It should be noted that the hinge mechanism provided in the embodiment of the present application can be applied to various smart terminals.

[0043] See also Figure 1 , Figure 3 and Figure 6 As shown, the hinge mechanism of the embodiment of the present application is used in a smart terminal, and includes: a base 100, a swing arm 200 and a torque-increasing component 300, wherein an installation space 110 can be set on the base 100, and a rotating shaft 120 extending along the second direction is respectively set on opposite sides of the installation space 110 along the first direction; there are at least two swing arms 200 corresponding to the rotating shaft 120, and each swing arm 200 is rotatably mounted on the corresponding rotating shaft 120, so that the swing arm 200 is rotatably set on both sides of the base, and a self-locking cam 210 is provided at one end of the swing arm 200 close to the base 100, that is, the end connected to the rotating shaft 120; the torque-increasing component 300 is arranged on the base 100, and the torque-increasing component 300 is configured so that when the swing arm 200 rotates relative to the base, the torque-increasing component 300 at least partially abuts against the self-locking cam 210.

[0044] In the embodiments of the present application, Figure 1 The X direction is the first direction, the Y direction is the second direction, the smart terminal includes two supports and a folding screen, two folding areas are symmetrically arranged on the folding screen, the chain mechanism is used to be arranged between the two folding areas, and the two screen supports are respectively arranged on the two folding areas.

[0045] Optionally, a rotating shaft 120 is respectively provided on two opposite sides of the installation space 110 of the base 100 along the first direction, and the two rotating shafts 120 extend along the second direction. The two swing arms 200 are respectively sleeved on the two rotating shafts 120, and the two swing arms 200 are respectively connected to the two screen support members, so that when the folding screen is folded or unfolded, the folding screen drives the two swing arms 200 to rotate relative to the base 100 around the rotating shaft 120 through the screen support member. When the swing arm 200 rotates relative to the base 100 around the rotating shaft 120, the protruding portion on the self-locking cam 210 at least partially abuts against the torque increasing component 300, so the torque increasing component 300 applies pressure along the first direction to the self-locking cam 210, so that a certain friction force is generated between the self-locking cam 210 and the torque increasing component 300, which can increase the torque friction of the swing arm 200, which is conducive to improving the hovering effect of the smart terminal.

[0046] Optionally, the self-locking cam 210 can be integrally provided with the swing arm 200, or can be an independent structure, and the embodiment of the present application does not limit this, as long as the self-locking cam 210 can rotate with the swing arm 200, and after the rotation, the self-locking cam 210 can at least partially contact with the torque-increasing component 300. Optionally, the self-locking cam 210 can also be configured so that the height of the protrusion changes with the angle of rotation. When the swing arm 200 rotates to different angles, different positions of the self-locking cam 210 abut against the torque-increasing component 300, so that different pressures and frictions are formed between the self-locking cam 210 and the torque-increasing component 300. In this way, according to the actual use requirements of the smart terminal, there is a large friction force within a preset angle range to improve the hovering effect, and in other angle ranges, the friction force is small and does not affect the rotation of the swing arm 200.

[0047] The hinge mechanism provided in the embodiment of the present application is such that when the folding screen is rotated to a certain angle so that the raised portion of the self-locking cam 210 on the swing arm 200 abuts against at least a portion of the torque increasing assembly 300, the torque increasing assembly 300 provides a greater friction force to the self-locking cam 210, thereby hindering the rotation of the swing arm 200, which helps to achieve the hovering of the folding screen and improve the hovering effect.

[0048] In some possible implementations, see Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the torque increasing assembly 300 of the embodiment of the present application includes: a torque slider 310 and an elastic member 320. The torque slider 310 can be two torque sliders 310 arranged relatively along a first direction. Each torque slider 310 can slide relative to the base 100 along the first direction. The two torque sliders 310 are respectively matched with the self-locking cams 210 of the two swing arms 200, and the two ends of the elastic member 320 are respectively abutted against the two torque sliders 310.

[0049] Optionally, the torque increasing assembly 300 includes an elastic member 320 and two torsion sliders 310, the two torsion sliders 310 are arranged on two opposite sides along the first direction and are slidably connected to the base 100, the elastic member 320 is arranged between the two torsion sliders 310, and the two ends of the elastic member 320 are respectively in contact with the two torsion sliders 310, the two ends of the elastic member 320 can be further fixedly connected with the torsion sliders 310 by tools such as glue, or can only contact with the two torsion sliders 310, and the embodiment of the present application does not limit this. A self-locking cam 210 is provided at the portion where the swing arm 200 is connected to the rotating shaft 120, and the positions of the two torsion sliders 310 correspond to the self-locking cam 210. When the swing arm 200 rotates around the rotating shaft 120 to a certain angle, the self-locking cam 210 rotates accordingly, so that the protruding portion on the self-locking cam 210 contacts the torsion slider 310. The two torsion sliders 310 are respectively squeezed by the corresponding self-locking cams 210 and slide toward each other along the first direction. At this time, the elastic member between the two torsion sliders 310 is compressed and elastically deformed. The elastic force of the elastic member pushes the two torsion sliders 310 to move back to back along the first direction, thereby increasing the pressure between the torsion slider 310 and the self-locking cam 210, and then increasing the friction between the torsion slider 310 and the self-locking cam 210. The friction provides a torque in the opposite direction of the rotation direction of the swing arm 200 to hinder the rotation of the swing arm 200, so that the swing arm 200 can be hovered, which is beneficial to improve the hovering effect of the folding screen.

[0050] Optionally, when the swing arm 200 rotates the raised portion of the self-locking cam 210 to disconnect from the torque slider 310, the self-locking cam 210 no longer squeezes the torque slider 310, and the torque slider 310 moves backward along the first direction under the action of the elastic force of the elastic member 320 to return to its original position, thereby achieving automatic resetting of the torque slider 310.

[0051] Optionally, the connection method between the two torsion sliders 310 and the base 100 is not limited in the embodiment of the present application, as long as the torsion slider 310 can slide relative to the base 100. Optionally, a sliding groove along the first direction is opened on the base 100, and the torsion slider 310 is slidably connected to the sliding groove.

[0052] In some embodiments, the two torsion sliders 310 are guided and matched along the first direction. In addition to the sliding connection structure between the two torsion sliders 310 and the base 100, there is also a sliding connection structure that cooperates with each other between the two torsion sliders 310, which is beneficial to ensure that the two torsion sliders 310 can move toward each other along the first direction when squeezed, avoiding the problem of misalignment of the torsion sliders 310.

[0053] In some possible implementations, see Figures 1 to 6As shown, the two torsion sliders 310 of the embodiment of the present application include a first torsion slider 311 and a second torsion slider 312. One of the first torsion slider 311 and the second torsion slider 312 is provided with a guide hole 3111 extending along a first direction, and the other is provided with a guide column 3121 adapted to the guide hole 3111. The guide column 3121 is inserted into the guide hole 3111 and slidably cooperates with the guide hole 3111, and the elastic member 320 is sleeved on the guide column 3121.

[0054] Optionally, a guide hole 3111 is provided on one of the first torque slider 311 and the second torque slider 312, and a guide column 3121 is provided on the other, and the guide column 3121 is partially inserted into the guide hole 3111 and slides in the guide hole 3111. In this way, when the first torque slider 311 and the second torque slider 312 are squeezed by the self-locking cam 210, the guide column 3121 slides along the extension direction of the guide hole 3111, thereby limiting the sliding path of the first torque slider 311 and the second torque slider 312, ensuring that the two can slide toward each other, and avoiding the first torque slider 311 and the second torque slider 312 from being squeezed and misaligned. At the same time, the elastic member 320 is sleeved on the guide column 3121, which also helps to ensure that the elastic member 320 is always located between the first torque slider 311 and the second torque slider 312, ensuring that the elastic member 320 can generate a sufficiently large elastic force when the first torque slider 311 and the second torque slider 312 are squeezed.

[0055] In some possible implementations, see Figure 1 , Figure 3 and Figure 6 As shown, the first torsion slider 311 and the second torsion slider 312 of the embodiment of the present application are provided with abutment protrusions 3122 protruding outwards in the first direction on their end surfaces away from each other, and the abutment protrusions 3122 abut against the corresponding self-locking cams 210 .

[0056] Optionally, the first torque slider 311 and the second torque slider 312 are provided with abutting protrusions 3122 on one end surface of the self-locking cam 210 corresponding to the first and second torque sliders 311 and 312, and the abutting protrusions 3122 abut against the self-locking cam 210. When the swing arm 200 rotates around the rotating shaft 120 relative to the base 100, the self-locking cam 210 pushes the first torque slider 311 and the second torque slider 312 to slide by squeezing the abutting protrusions 3122. In addition, the shape of the abutting protrusions 3122 is not limited in the embodiment of the present application. Optionally, the abutting protrusions 3122 can be set to be strips extending along the second direction, which helps to increase the contact area between the self-locking cam 210 and the abutting protrusions 3122, thereby better pushing the first torque slider 311 and the second torque slider 312 to slide.

[0057] In some possible implementations, see Figures 1 to 6As shown, the outer peripheral surface of the self-locking cam 210 of the embodiment of the present application includes a torque-increasing section 211 and a constant torque section 212. When the swing arm 200 rotates and the torque-increasing section 211 abuts against the torque slider 310, the torque-increasing section 211 is suitable for pushing the torque slider 310 to slide. Optionally, the constant torque section 212 can be set as an arc surface. When the constant torque section 212 abuts against the torque slider 310, the position of the torque slider 310 relative to the base 100 remains unchanged.

[0058] It should be noted that the smart terminal only needs to have a good hovering effect within a preset angle range to meet the use needs of the smart terminal. Optionally, when the angle between the two folding areas of the folding screen is less than or equal to 150 degrees, it is necessary to increase the resistance to the rotation of the swing arm 200 to improve the hovering effect. When the angle between the two folding areas is greater than 150 degrees, there is no need to increase the resistance so that the swing arm 200 can rotate smoothly and the folding screen can be quickly unfolded. The specific angle range can be adjusted according to actual needs, and the embodiment of the present application does not limit this.

[0059] Optionally, the outer peripheral surface of the self-locking cam 210 is required to be provided with a torque-increasing section 211 and a constant torque section 212. When the angle between the two folding areas of the folding screen is small, the swing arm 200 rotates until the torque-increasing section 211 abuts against the torsion slider 310, and the torque-increasing section 211 pushes the two torsion sliders 310 to slide toward each other, thereby squeezing the elastic member 320, increasing the pressure between the self-locking cam 210 and the torsion slider 310, and then increasing the friction between the self-locking cam 210 and the torsion slider 310, hindering the rotation of the swing arm 200 and improving the hovering effect. When the angle between the two folding areas of the folding screen is large, when the swing arm 200 rotates until the constant torque section 212 abuts against the torsion slider 310, the constant torque section 212 does not generate a squeezing force on the torsion slider 310, and the torsion slider 310 does not slide. Therefore, the swing arm 200 will not be subject to additional resistance, which is conducive to the smooth rotation of the swing arm 200 and the rapid unfolding of the folding screen.

[0060] In some possible implementations, see Figure 1 , Figure 6 and Figure 7 As shown, the torque increasing assembly 300 of the embodiment of the present application also includes: a slider base 330, there are two slider bases 330, the two slider bases 330 are arranged in the installation space 110, and are respectively arranged on both sides of the torque slider 310 along the second direction, and the slider base 330 is provided with a slide rail 331 extending along the first direction on the side facing the torque slider 310, and each torsion slider 310 is slidably matched with the two slide rails 331 at both ends along the first direction.

[0061] Optionally, two slider bases 330 are fixed in the installation space 110, two torsion sliders 310 are arranged between the two slider bases 330, and slide rails 331 are provided on the slider bases 330. Both ends of the torsion slider 310 along the second direction are located in the slide rails 331 and are slidably connected to the slide rails 331, thereby realizing the sliding of the torsion slider 310 relative to the base 100 along the first direction. The slider base 330 can preferably play a role in limiting the position of the torsion slider 310, preventing the torsion slider 310 from falling off or misaligning, which is conducive to ensuring the stability of the hinge mechanism.

[0062] In some possible implementations, see Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the torque increasing assembly 300 of the embodiment of the present application includes: a fixing member 340, which may be two fixing members 340, and the two fixing members 340 are respectively arranged on the side of the two slider bases 330 along the second direction facing away from the torque slider 310, and the two fixing members 340 are respectively fixedly connected to the corresponding slider bases 330.

[0063] In some embodiments, the slider base 330 is fixed in the installation space 110 through the fixing member 340. In order not to affect the sliding of the two torsion sliders 310, the two fixing members 340 are respectively arranged on the side of the two slider bases 330 facing away from the torsion sliders 310. Optionally, the specific structure of the fixing member 340 and the connection method between the fixing member 340 and the slider base 330 are not limited in the embodiment of the present application, and the slider base 330 can be fixed in the installation space 110. Optionally, the two fixing members 340 are the bracket 341 and the self-locking structure 342 on the hinge mechanism, and a fixing shaft extends from each of the two fixing members 340. The slider base 330 is provided with a corresponding mounting hole, and the fixing shaft is inserted into the mounting hole to fix the slider base 330.

[0064] In some possible implementations, see Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the slider base 330 of the embodiment of the present application is provided with a fixing groove 332 opening along the second direction on the side facing away from the torsion slider 310 along the second direction, and the fixing member 340 has a pressing portion 3411 extending along the second direction, and the pressing portion 3411 extends into the fixing groove 332 to fix the slider base 330.

[0065] Optionally, a fixing groove 332 is provided on the slider base 330, and a pressing portion 3411 extends from the fixing member 340, and the pressing portion 3411 is inserted into the fixing groove 332, so as to fix the slider base 330 in the installation space 110. Optionally, the pressing portion 3411 can be set to be interference fit with the fixing groove 332 to improve the stability of the connection between the slider base 330 and the fixing member 340, to ensure that the slider base 330 remains stationary when the torsion slider 310 slides, and the pressing portion 3411 can also be coated with glue or other reinforcing materials to further reinforce it, or the pressing portion 3411 and the fixing groove 332 can be welded together, and the specific reinforcement method between the pressing portion 3411 and the fixing groove 332 is not limited in the embodiment of the present application.

[0066] In some possible implementations, see Figure 1 , Figure 2 and Figure 8 As shown, the embodiment of the present application also includes a damping gear 400, which is provided in two. The two damping gears 400 are arranged side by side along the first direction in the installation space 110, and the two damping gears 400 are located between the two swing arms 200. The damping gear 400 and the torque increasing assembly 300 are spaced apart along the second direction, and meshing teeth are also provided at one end of each swing arm 200 facing the rotating shaft 120, and the meshing teeth are meshed with the damping gear 400.

[0067] In some embodiments, two damping gears 400 are further provided in the installation space 110, and the damping gears 400 mesh with the meshing teeth on the swing arm 200. When the swing arm 200 rotates relative to the base 100, the damping gears 400 provide a certain damping force to hinder the rotation of the swing arm 200. The damping force provided by the damping gears 400 is constant, so that when the swing arm 200 rotates until the self-locking cam 210 abuts against the constant torsion section 212, the damping gears 400 can also provide a certain resistance, and under the premise of not affecting the rotation of the swing arm 200, the swing arm 200 is prevented from rotating too fast, thereby improving the stability of the folding screen when it is unfolded or folded.

[0068] See also Figure 1 As shown, the embodiment of the present application further provides a smart terminal, comprising: any of the above-mentioned hinge mechanisms. Optionally, the smart terminal further comprises a support member, two support members, the two support members are respectively arranged on both sides of the hinge mechanism, and are respectively connected to the two swing arms 200; a folding screen, the folding screen comprises a folding area corresponding to the support member, and each folding area is connected to the corresponding support member.

[0069] Optionally, the structure and working principle of the hinge mechanism are described in detail in the above embodiments and will not be described in detail here.

[0070] In an embodiment of the present application, the smart terminal includes the above-mentioned hinge mechanism, two support members and a folding screen. The folding screen includes two symmetrically arranged folding areas. The support members are correspondingly connected to the folding areas. The hinge mechanism is arranged between the two support members, and the swing arm 200 of the hinge mechanism is correspondingly connected to the support members. In this way, when the folding screen is folded or unfolded, the folding area drives the swing arm 200 to rotate relative to the base 100 through the support member. The swing arm 200 is subjected to the resistance to rotation provided by the damping gear 400 and the torque slider 310, so that the unfolding or folding of the folding screen has a strong damping feeling, which is beneficial to improving the hovering effect of the folding screen.

[0071] In summary, the hinge mechanism and the smart terminal provided in the embodiment of the present application, the smart terminal includes a hinge mechanism, a folding screen and two support members, the hinge mechanism includes a base 100, a swing arm 200 assembly and a torque increasing assembly 300, the swing arm 200 assembly includes two swing arms 200, the torque increasing assembly 300 includes a torsional elastic member 320 and two torsion sliders 310, the support member is correspondingly connected to the folding area of ​​the folding screen, the hinge mechanism is arranged between the two support members, and the two swing arms 200 are correspondingly connected to the two support members, the base 100 is provided with a rotating shaft 120 on two opposite sides along the first direction, the swing arm 200 is sleeved on the rotating shaft 120 and a self-locking cam 210 is provided at one end of the swing arm 200 connected to the rotating shaft 120, the torsion slider 310 is relatively arranged between the two self-locking cams 210 along the first direction and slidably cooperates with the base 100, and the elastic member 320 is arranged between the two torsion sliders 310. In this way, when the folding screen is folded or unfolded, the folding screen drives the swing arm 200 to rotate relative to the base 100 around the rotating shaft 120 through the support member. The rotation of the swing arm 200 drives the self-locking cam 210 to rotate, thereby squeezing the two torsion sliders 310, so that the two torsion sliders 310 slide toward each other to compress the elastic member 320. The elastic force of the elastic member 320 pushes the torsion slider 310 in the opposite direction to increase the pressure between the torsion slider 310 and the self-locking cam 210, thereby increasing the friction between the torsion slider 310 and the self-locking cam 210, thereby hindering the rotation of the self-locking cam 210 and providing greater resistance to the rotation of the swing arm 200, which is beneficial to improving the hovering effect of the folding screen and enhancing the damping feeling when the folding screen is folded or unfolded.
