The detailed description and technical content of this new model are described as follows in conjunction with the drawings:

Please refer to FIG. 1 to FIG. 5 , the present invention provides a hinge 100 with variable torque, and the hinge 100 includes a base 10 , a rotating group 20 and a torque providing piece 30 . The base 10 forms an installation space 11 and two guide blocks 12 located in the installation space 11 . The guide blocks 12 are located on two opposite sides of the base 10 and protrude toward the installation space 11 . In one embodiment, the base 10 is composed of a base body 13 and a frame 14, the frame 14 is formed with the guide block 12, the frame 14 is assembled on the base body 13, the frame 14 and the base body 13 are in common The installation space 11 is defined.

Moreover, the rotating group 20 is arranged in the installation space 11, and the rotating group 20 includes two first arc-shaped parts 21 arranged at intervals, and a second arc-shaped part 22 located between the two first arc-shaped parts 21. , the two first arc-shaped pieces 21 are respectively located on two opposite sides of the base 10, and the two first arc-shaped pieces 21 respectively form a guide groove 211, and the guide groove 211 provides one of the two guide blocks 12 During the movement, the second arc-shaped member 22 is operated when the hinge 100 is to be opened and closed, and the second arc-shaped member 22 drives the two first arc-shaped members 21 after rotating. In addition, the torsion providing piece 30 is combined with the base 10 and faces the rotating group 20, the torsion providing piece 30 is shaped as a protrusion 31 located in the installation space 11, the protrusion 31 protrudes toward the rotating group 20, and It can produce elastic deformation after being stressed.

As mentioned above, the two first arc-shaped pieces 21 and the second arc-shaped piece 22 respectively have a contact surface 212, 221 which is in contact with the protrusion 31. The plurality of contact surfaces 212, 221 have different curvatures. The two first arcs The shaped part 21 and the second arc-shaped part 22 are sequentially opened and closed relative to the base 10 based on the rotation angle of the rotating group 20, and the contact positions of the plurality of contact surfaces 212, 221 and the protrusion 31 are changed during rotation, so that The torsional force borne by the rotating group 20 changes.

Regarding the implementation of the hinge 100 , please refer back to FIG. 1 to FIG. 5 , assuming that the hinge 100 is in an open state initially, and the second arc-shaped member 22 does not rotate relative to the base 10 . When the hinge 100 is about to be closed, the second arc-shaped member 22 is forced to rotate relative to the base 10 , and the second arc-shaped member 22 uses the contact surface of the second arc-shaped member 22 during the rotation process. 221 is in contact with the protrusion 31 to make the rotating group 20 bear a first torque. After the second arc-shaped piece 22 rotates to a certain angle, the second arc-shaped piece 22 drives the two first arc-shaped pieces 21, so that the two first arc-shaped pieces 21 are guided by the two guide blocks 12 Rotate relative to the base 10. At this time, the rotating group 20 uses the two contact surfaces 212 of the two first arc-shaped members 21 to contact the protrusion 31 and bear a second torsion force. Due to the different curvatures of the contact surface 221 of the second arc-shaped member 22 and the two contact surfaces 212 of the two first arc-shaped members 21 , the second torsion force is different from the first torsion force. That is to say, when the rotating group 20 contacts the protrusion 31 through the two contact surfaces 212 of the two first arc-shaped members 21 , the torsional force borne by the rotating group 20 will be changed. Moreover, when the hinge 100 returns, the rotating group 20 contacts the protrusion 31 with the two contact surfaces 212 of the two first arc-shaped members 21 and the contact surface 221 of the second arc-shaped member 22 in sequence, After the rotation group 20 changes the contact position with the protrusion 31 , the torsion force borne by the rotation group 20 is changed from the second torsion force to the first torsion force.

As can be seen from the above, the curvature of the plurality of contact surfaces 212, 221 of the present invention is different, so that the rotation group 20 contacts the protrusion 31 with different contact surfaces 212 (221) during the rotation process, so that the torque providing piece 30 can be Available in different torques. Based on this, the present invention can solve the problem that the conventional hinge 100 cannot be rotated or fixed smoothly due to the limitation of the fixed torsion force during the opening and closing process of the conventional hinge 100 .
