The hinge device is connected with one machine body through a rotating shaft, the bearing frame is connected with the other machine body, and the hinge device provides the two machine bodies to be relatively unfolded and closed.

The torsion generating element utilizes the stacking of the elastic sheets to generate axial thrust to push the friction plates to cause friction to generate torsion, utilizes the locking degree of the nut to adjust the torsion, and utilizes the matching of the concave cams to enable the hinge device to have an automatic closing (auto lock) function. The so-called auto-close function is that when the angle between the two bodies of the electronic device is smaller than a specific angle (e.g. 30 degrees), the torque force will be reduced, so that the upper body can freely fall down onto the lower body.

In addition, directional terms referred to in the following examples, for example: upper, lower, left, right, front, rear, etc. are directions with reference to the drawings only, and thus, directional terms used are for explanation and not for limitation of the present invention.
Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a perspective view of a hinge according to a first embodiment of the present invention; FIG. 2 is a partial exploded view of FIG. 1; fig. 3 is an exploded view of the structure of fig. 1. First, the components of the overall structure of the hinge device and the assembly method thereof will be described in detail. The hinge device 1 comprises a rotating shaft 10, a supporting frame 20 and two friction components 30. The frame 20 includes a pivot portion 21, the pivot portion 21 is pivoted to the shaft 10 and has a first connecting portion 211. Two friction components 30 are sleeved on the rotating shaft 10. Each friction assembly 30 includes a first friction member 31 and a second friction member 32. The first friction member 31 is pivotally connected to the rotating shaft 10, and the first friction member 31 has a second butt-joint portion 311 and a first stop portion 312; the second connection portion 311 is matched with the first connection portion 211, so as to connect the first friction member 31 to the pivot portion 21 of the frame 20 when the friction member 30 is adjacent to the pivot portion 21 of the frame 20. The second friction member 32 is sleeved and clamped on the rotating shaft 10, and the second friction member 32 has a second stopping portion 321; the second stopping portion 321 cooperates with the first stopping portion 312 to limit the rotatable angle of the second friction member 32 relative to the first friction member 31, and thus the rotatable angle of the rotating shaft 10 relative to the supporting frame 20.
In the present embodiment, the first docking portion 211 is a groove extending along the axial direction of the rotating shaft 10 on the pivoting portion 21, and the second docking portion 311 is a convex pillar extending along the axial direction of the rotating shaft 10 on the first friction element 31. The first friction member 31 is connected to the pivot portion 21 of the frame 20 by the engagement of the second engagement portion 311 with the groove-shaped first engagement portion 211, and the second friction member 32 is clamped between the first friction member 31 and the pivot portion 21. The two friction members 30 are respectively located at two sides of the pivoting portion 21 of the support frame 20.
The hinge 1 further comprises a pressing member 40; in the present embodiment, the pressing member 40 is a nut, but is not limited thereto. The shaft 10 includes a shaft 11 and a head 12 fixed to the shaft 11, and the head 12 has a diameter larger than that of the shaft 11. The pivot portion 21 of the frame 20, the friction element 30 and the pressing element 40 are sleeved on the shaft portion 11 of the rotating shaft 10, and the pivot portion 21 of the frame 20 and the friction element 30 are located between the head portion 12 and the pressing element 40. The pressing member 40 is used for pressing the pivoting portion 21 of the support frame 20 and the friction element 30, so that the friction element 30 can generate friction to provide a torque force when the rotating shaft 10 and the support frame 20 rotate relatively.
The hinge device 1 further comprises a concave-convex wheel assembly 50, wherein the concave-convex wheel assembly 50 is sleeved on the shaft portion 11 of the rotating shaft 10 and is located between the pivoting portion 21 of the supporting frame 20 and the pressing member 40. The concavo-convex wheel assembly 50 includes a first concave-convex wheel 51 and a second concave-convex wheel 52 adjacent to each other, the first concave-convex wheel 51 is pivoted on the shaft portion 11 of the rotating shaft 10, and the second concave-convex wheel 52 is sleeved and clamped on the shaft portion 11 of the rotating shaft 10. The first friction member 31 of the friction assembly 30 further has a third abutment portion 313, and the first concave-convex cam 51 has a fourth abutment portion 511. The third and fourth butting portions 313 and 511 are matched to connect the first concave-convex cam 51 and the first friction member 31 of the adjacent friction assembly 30 with each other. The matching between the first concave-convex wheel 51 and the second concave-convex wheel 52 of the concave-convex wheel component 50 enables the hinge device to have an automatic closing function.
In the present embodiment, the third abutting portion 313 is a groove extending in the axial direction of the rotating shaft 10 on the first friction member 31, and the fourth abutting portion 511 is a boss extending in the axial direction of the rotating shaft 10 on the first concave-convex cam 51. The first concave-convex wheel 51 is connected to the first friction piece 31 of the adjacent friction assembly 30 by the convex column type fourth butt-joint part 511 being clamped in the groove type third butt-joint part 313.
The hinge 1 further comprises a plurality of elastic members 60 and a sound deadening member 70; in the present embodiment, the elastic member 60 is a spring, but is not limited thereto, and for example, a spring may be used instead of the spring. The elastic member 60 and the noise damping member 70 are sleeved on the shaft 11 of the rotating shaft 10 and located between the pivot portion 21 of the bracket 20 and the pressing member 40. The elastic members 60 are stacked and can be pressed by the pressing member 40 to generate an axial thrust when the rotating shaft 10 and the carrier 20 rotate relatively, so that the friction assembly 30 generates friction to provide a torsion force. The noise deadening member 70 reduces the sound generated by the pivoting torque force.
Next, the operation of the hinge of the present invention will be described in detail. The hinge device of the present invention utilizes the elastic member 60 to generate axial thrust, push the friction component 30 to generate friction to generate torque, and utilizes the tightness of the tightening member 40 to adjust the torque. Since the first friction member 31 of the friction assembly 30 is connected to the pivot portion 21 of the frame 20, and the first friction member 31 and the pivot portion 21 of the frame 20 are both pivoted to the rotating shaft 10, the first friction member 31 and the frame 20 rotate together relative to the rotating shaft 10. Since the second friction member 32 of the friction assembly 30 is sleeved and fastened on the rotating shaft 10, the second friction member 32 and the rotating shaft 10 rotate together. Since the first friction member 31 rotates relative to the rotating shaft 10 and the second friction member 32 rotates together with the rotating shaft 10, the first stopping portion 312 is disposed on the first friction member 31 and the second stopping portion 321 is disposed on the second friction member 32, so as to limit the relative rotation angle between the first friction member 31 and the second friction member 32, and further limit the relative rotation angle between the rotating shaft 10 and the support frame 20.
In addition, since the first concave-convex wheel 51 of the concave-convex wheel assembly 50 is connected with the first friction member 31 of the adjacent friction assembly 30, and the first friction member 31 is connected with the pivot portion 21 of the support frame 20, the first concave-convex wheel 51 of the concave-convex wheel assembly 50 is connected with the pivot portion 21 of the support frame 20 through the first friction member 31, which is equivalent to the concave-convex wheel connected with the support frame in the prior art, but the concave-convex wheel assembly 50 of the present invention is connected with the adjacent friction assembly 30 without limiting the sleeving number of the friction assemblies 30, and more friction assemblies 30 can be sleeved according to the requirement to generate a larger torsion force.

For clarity, the first friction member 31 of the friction assembly 30 is shown in solid lines, the second friction member 32 is shown in broken lines, and the second friction member 32 does not cover the first friction member 31. In the present embodiment, the second abutting portions 311 of the first friction member 31 are studs and are two in number, and the third abutting portions 313 of the first friction member 31 are grooves and are two in number; the two stud-type second abutting portions 311 and the two groove-type third abutting portions 313 are uniformly distributed on the entire circumference of the first friction member 31. The first stopping portions 312 of the first friction member 31 are sides of the protruding pillars, so the number of the first stopping portions 312 is two and is denoted by 312a and 312 b; the second friction member 32 has a protrusion at its periphery, and two sides of the protrusion are the second stopping portions 321, so the number of the second stopping portions 321 is two and is indicated as 321a and 321 b. When the first stopping portion 312a abuts against the second stopping portion 321a, the second friction element 32 can rotate clockwise until the first stopping portion 312b abuts against the second stopping portion 321b, during which the second friction element 32 rotates relative to the first friction element 31, that is, the rotating shaft 10 rotates relative to the support frame 20.
Referring to fig. 5, fig. 5 is an exploded view of a hinge according to a second embodiment of the present invention. Compared with the hinge device 1 shown in fig. 1 and 2, the hinge device shown in fig. 5 is only sleeved with a friction element 30 on one side of the pivot portion 21 of the support frame 20, and the friction element 30 is sleeved on the shaft 10 and located between the head 12 of the shaft 10 and the pivot portion 21 of the support frame 20. It should be noted that the concave-convex wheel assembly 50 is directly connected to the pivot portion 21 of the support frame 20; specifically, the convex-column-type fourth abutting portion 511 is engaged with the groove-type first abutting portion 211, so that the first concave-convex wheel 51 is connected to the pivot portion 21 of the bracket 20.
Referring to fig. 6, fig. 6 is an exploded view of a hinge according to a third embodiment of the present invention. Compared with the hinge device 1 shown in fig. 1 and 2, the hinge device shown in fig. 6 is only sleeved with a friction component 30 on one side of the pivoting portion 21 of the support frame 20, and the friction component 30 is sleeved on the rotating shaft 10 and located between the pivoting portion 21 of the support frame 20 and the concave-convex wheel component 50.

Compared with the hinge device 1 shown in fig. 1 and 2, the hinge device shown in fig. 7 is provided with two friction elements 30 respectively sleeved on two sides of the pivoting portion 21 of the supporting frame 20, and at least one of the two sides is provided with more than two friction elements 30. In this embodiment, two friction assemblies 30 are respectively sleeved on two sides of the pivot portion 21 of the support frame 20. At this time, the two friction members 30 sleeved on each side of the pivotal connection portion 21 of the support frame 20 are adjacent to each other. The groove-type third abutting portion 313 of one of the first friction members 31 of two adjacent friction assemblies 30 is engaged with the convex column-type second abutting portion 311 of the other first friction member 31, so that the two first friction members 31 of two adjacent friction assemblies 30 are connected with each other.

In summary, the hinge device of the present invention utilizes the first friction element of the friction element to connect to the frame when the friction element abuts against the frame, and to connect to another friction element when the friction element abuts against another friction element, so that a plurality of friction elements can be connected in series according to the required torque. The pivot device also utilizes the cooperation of the first friction piece and the second friction piece of the friction component to limit the rotatable angle of the rotating shaft relative to the bearing frame. In addition, the hinge device of the present invention can be connected to the friction component by using the concave-convex wheel component to further connect to the support frame (as shown in fig. 2, fig. 6 and fig. 7), or directly connect to the support frame (as shown in fig. 5), so that the hinge device has an automatic closing function, but does not limit the space for sleeving the friction component.
