[0062] In the related art, the hovering mechanism includes two cams arranged opposite to each other, and there is sliding friction between the two cams. After long-term use, the end surface of the cam is prone to wear, and the wear position is single and fixed, and the wear position is mainly concentrated at the connection position between the top surface and the slope surface. The slope of the slope surface will decrease due to wear, resulting in a decrease in the tangential force of the slope surface, resulting in a decrease in the resistance that hinders the rotation of the cam, which is easy to affect the hovering effect of the smart terminal.

[0063] In view of this, the present application provides a hovering mechanism, which, by setting a rolling member, rotates along the end face cam in the movable frame during the rotation of the torque member, so that the friction between the rolling member and the end face cam is rolling friction, which can greatly reduce the friction between the rolling member and the end face cam, thereby reducing wear and increasing service life, making the movement resistance of the torque member stable and ensuring the hovering effect.

[0064] The following describes the hovering mechanism, hinge and smart terminal provided by the embodiments of the present utility model with reference to the accompanying drawings.

[0065] refer to Figure 1 and Figure 2 As shown, the present application provides a suspension mechanism, which is applied to a hinge. The suspension mechanism includes a damping assembly 20 and a torsion assembly. The damping assembly 20 includes a movable frame 21 and an elastic member 22. The elastic member 22 is configured to provide an obstructive force for the movement of the movable frame 21 along a first direction; the torsion assembly includes a torsion member 30 and a rolling member 40. The rolling member 40 is rotatably arranged between the movable frame 21 and the torsion member 30. The torsion assembly is used to provide an obstructive force for the movement of the movable frame 21 in the opposite direction to the first direction.

[0066] A hovering mechanism provided in the present application is provided with a rolling member 40. During the rotation of the torque member 30, the friction between the rolling member 40 and the torque member 30 is rolling friction, which can greatly reduce the friction between the rolling member 40 and the torque member 30, thereby reducing the problem of wear on the end surface of the torque member 30, increasing the service life of the torque member 30, making the movement resistance of the torque member 30 stable, and ensuring the hovering effect.

[0067] The torque member 30 is a key component for achieving the hovering effect. In the existing structure, the torque member 30 is prone to wear. Compared with the existing structure, in the present application, the torque member 30 includes an end face cam 31. During the rotation of the torque member 30, the end face cam 31 rotates relative to the rolling member 40, so that the rolling member 40 rotates along the end face cam 31 in the movable frame 21, so as to form rolling friction between the rolling member 40 and the end face cam 31. During the rotation of the torque member 30, the end face cam 31 rotates relative to the rolling member 40, so that the rolling member 40 rotates along the end face cam 31 in the movable frame 21, so as to form rolling friction between the rolling member 40 and the end face cam 31.

[0068] The first direction reference Figure 1 and Figure 2 The first direction is the direction indicated by the arrow Y in the figure, and the elastic member 22 is elastically compressed. Since the movement of the movable frame 21 along the first direction needs to overcome the elastic force of the elastic member 22, that is, the elastic member 22 provides an obstruction force for the movement of the movable frame 21 along the first direction, which increases the difficulty of the movable frame 21 moving along the first direction.

[0069] The present application provides a hovering mechanism, in which a rolling member 40 is provided. During the rotation of the torque member 30, the rolling member 40 rotates along the end face cam 31 in the movable frame 21, so that the friction between the rolling member 40 and the end face cam 31 is rolling friction, which can greatly reduce the friction between the rolling member 40 and the end face cam 31, thereby reducing the problem of wear on the end face of the end face cam 31, increasing the service life of the end face cam 31, making the movement resistance of the torque member 30 stable, and ensuring the hovering effect.

[0070] refer to Figure 3 and Figure 4 As shown, the end face cam 31 and the rolling member 40 abut against each other. During the rotation of the torque member 30 , the rolling member 40 rolls along the end face cam 31 to provide resistance to the movement of the torque member 30 .

[0071] In one possible implementation, a groove 311 and a protrusion 312 are provided on a side of the end face cam 31 facing the movable frame 21, and the grooves 311 and the protrusions 312 are arranged at intervals along the edge of the end face cam 31; the rolling member 40 includes a matching portion 42, and the matching portion 42 is rollingly arranged along the groove 311 and the protrusion 312.

[0072] In this example, the end face cam 31 is cylindrical, and a groove 311 and a protrusion 312 are provided on the side of the end face cam 31 facing the rolling member 40, so the side of the end face cam 31 facing the rolling member 40 is uneven. During the rotation of the torque member 30, the groove 311 and the protrusion 312 of the end face cam 31 alternately abut against the rolling member 40. In the process of switching from the abutment of the groove 311 with the rolling member 40 to the abutment of the protrusion 312 with the rolling member 40, the end face cam 31 pushes the movable frame 21 to move in the first direction, and the elastic member 22 provides an obstructive force for the movement of the movable frame 21 in the first direction, thereby achieving a hovering effect.

[0073] In a possible implementation, the number of the grooves 311 may be 2, 3 or more, the number of the protrusions 312 is consistent with the number of the grooves 311 , and the grooves 311 and the protrusions 312 are arranged at intervals along the edge of the end face cam 31 .

[0074] In one possible implementation, the bottom surface of the groove 311 can be a plane or a curved surface, the protrusion 312 includes a top surface 3122 and a transition surface 3121, the transition surface 3121 is located between the two sides of the top surface 3122 and the bottom surface of the groove 311, and the transition surface 3121 can be a slope or an arc surface.

[0075] During the rotation of the torque member 30, the matching portion 42 rolls from the position in the groove 311 along a transition surface 3121 of the protrusion 312 until it rolls to contact the top surface 3122 of the protrusion 312, and then rolls along another transition surface 3121 of the protrusion 312 into the groove 311, and repeats this process, which is the process of the matching portion 42 rolling along the groove 311 and the protrusion 312. During the rotation of the torque member 30, the friction between the transition surface 3121, the top surface 3122, and the groove 311 and the matching portion 42 is rolling friction, so the wear between the rolling member 40 and the end face cam 31 can be reduced, and the service life of the rolling member 40 and the end face cam 31 can be increased.

[0076] In one possible implementation, a smart terminal equipped with a hovering mechanism, when the smart terminal is in a folded state or a flattened state, the mating portion 42 of the rolling element 40 abuts against the top surface 3122, and the preload force generated between the end face cam 31 and the mating portion 42 maintains the smart terminal in a folded state or a flattened state, thereby achieving a hovering effect.

[0077] In one possible implementation, reference Figure 3 and Figure 4 As shown, the rolling element 40 further includes a roller portion 41, and two matching portions 42 are respectively arranged at two ends of the roller portion 41. The two matching portions 42 can respectively match with the two end surface cams 31.

[0078] In one possible implementation, the mating portion 42 is conical in shape, having a large end and a small end, wherein the diameter of the large end is greater than the diameter of the small end, the large end is one end of the mating portion 42 connected to the roller portion 41, and the small end is one end of the mating portion 42 away from the roller portion 41.

[0079] When the matching portion 42 is in a conical shape, the bottom surface of the groove 311 is a plane, the top surface 3122 of the protrusion 312 can be a plane, and the transition surface 3121 can be an inclined surface or an arc surface.

[0080] In a possible implementation, the mating portion 42 may be spherical, such as a spherical or elliptical shape, which is beneficial to reduce the friction between the mating portion 42 and the end face cam 31, reduce the wear of the mating portion 42 and the end face cam 31, and improve the service life. Of course, the mating portion 42 may also be hemispherical, which is beneficial to reduce the space occupied by the mating portion 42.

[0081] When the matching portion 42 is spherical or hemispherical, the bottom surface of the groove 311 is a curved surface, and the top surface 3122 and the transition surface 3121 of the protrusion 312 are arc-shaped surfaces, so that the matching portion 42 can better roll along the groove 311 and the protrusion 312 to reduce friction.

[0082] In one possible implementation, reference Figure 3 and Figure 4 As shown, a limiting groove 211 is provided on one side of the movable frame 21 facing the torque member 30, and the rolling member 40 is rotatably arranged in the limiting groove 211. In this example, the rolling member 40 can be directly placed in the limiting groove 211, and during the rotation of the torque member 30, the end face cam 31 contacts and pushes the matching portion 42 of the rolling member 40, so that the rolling member 40 rotates in the limiting groove 211 with the central axis of the rolling member 40 as the center of rotation.

[0083] The limiting groove 211 is used to limit the movement of the rolling element 40 and improve the stability of the movement of the rolling element 40. In order to improve the smoothness of the movement of the rolling element 40, lubricating oil is applied between the limiting groove 211 and the rolling element 40 to reduce the obstruction of the limiting groove 211 to the rotation of the rolling element 40.

[0084] In one possible implementation, the limit groove 211 can be a structure that is recessed into the movable frame 21. The length of the limit groove 211 is consistent with the length of the rolling element 40, which can prevent the rolling element 40 from moving in the limit groove 211 in the length direction of the limit groove 211, thereby ensuring the stability of the contact between the rolling element 40 and the end face cam 31, thereby ensuring a stable hovering effect.

[0085] In one possible implementation, reference Figure 5 As shown, the roller portion 41 and the matching portion 42 are integrally connected, which means that the roller portion 41 and the matching portion 42 are integrally formed and connected. Such a structure has high connection reliability and does not require assembly, thus having the advantage of low cost.

[0086] In one possible implementation, reference Figure 6 and Figure 7 As shown, at least one end of the roller portion 41 is provided with a mounting post 411, and the matching portion 42 is rotatably arranged on the mounting post 411. Such a structure can improve the flexibility of the matching portion 42, which is conducive to significantly reducing the friction between the rolling element 40 and the end face cam 31, thereby reducing wear and improving service life.

[0087] The roller portion 41 may be provided with a mounting post 411 at only one end, or may be provided with mounting posts 411 at both ends of the roller portion 41 , the central axis direction of the mounting post 411 is consistent with the central axis direction of the roller portion 41 , and the matching portion 42 rotates around the mounting post 411 . Figure 6 , Figure 8 and Fig. 9 As shown, while the rolling element 40 rotates in the limiting groove 211 , the matching portion 42 can rotate around the mounting column 411 , so that the rotation of the matching portion 42 is more flexible, which helps to reduce the friction between the rolling element 40 and the end face cam 31 .

[0088] In the absence of the fixing base 10 , the damping assembly 20 and the torsion assembly may be arranged on the central axis 50 of the hinge.

[0089] refer to Figure 1 and Figure 2 As shown, the suspension mechanism further includes a fixed seat 10, a movable frame 21 is disposed on the fixed seat 10, and a torsion member 30 is disposed on opposite sides of the fixed seat 10. In a possible implementation, referring to Fig.10 , Fig.11 and Fig.12As shown, a first stopper 11 is disposed at the first end of the fixing seat 10 , a second stopper 12 is disposed at the second end of the fixing seat 10 , an elastic member 22 is disposed between the first stopper 11 and the movable frame 21 , and a torque member 30 is rotatably connected to the second stopper 12 .

[0090] The elastic member 22 can be a compression spring or an elastic sleeve. The elastic member 22 provides damping for the movement of the movable frame 21 on the fixed seat 10 along the first direction. The elastic force of the elastic member 22 hinders the movable frame 21 from moving along the first direction. When the movable frame 21 moves along the first direction to squeeze the elastic member 22, the elastic member 22 is compressed and applies a thrust toward the end face cam 31 to the movable frame 21, so that the mating portion 42 of the rolling member 40 abuts against the end face cam 31.

[0091] In one possible implementation, reference Fig.12 and Fig.13 As shown, the fixing seat 10 further includes a guide shaft 13 disposed between the first stop portion 11 and the second stop portion 12 , and the guide shaft 13 penetrates the elastic member 22 , the movable frame 21 and the end face cam 31 .

[0092] The guide shaft 13 guides the elastic compression of the elastic member 22 and the movement of the movable frame 21 along the first direction, and can also prevent the movable frame 21 from being squeezed out.

[0093] In one possible implementation, reference Figure 8 and Fig.10 As shown, two guide holes 213 are defined in the movable frame 21 , the limiting groove 211 is located between the two guide holes 213 , and the guide shaft 13 is passed through the guide hole 213 .

[0094] In the absence of external force, the elastic member 22 pushes the movable frame 21 under the action of its own elastic force, and the movable frame 21 squeezes the rolling member 40, so that the rolling member 40 and the end face cam 31 are pressed against each other, so that during the rotation of the torque member 30, the matching portion 42 of the rolling member 40 can be stably maintained in the groove 311 or maintained in contact with the top surface 3122 of the protrusion 312, so that the angle between the two torsion members 30 can be positioned at multiple angles to achieve a hovering effect, thereby improving the convenience of use.

[0095] The smart terminal equipped with the hovering mechanism can maintain the folding angle of the body of the smart terminal at a specific angle, achieve a better hovering effect, prevent the body from falling back freely, and improve the stability of use. In addition, since the hovering mechanism provided in this embodiment is not prone to wear and tear, the service life of the smart terminal is increased.

[0096] In one possible implementation, reference Fig. 9 and Fig.10 As shown, the torque member 30 also includes a first gear 32 and a connecting portion 33. The first gear 32 is spaced apart from the end face cam 31, and the center axis of the first gear 32 is parallel to the center axis of the end face cam 31.
