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

Referring to FIGS. 1 to 7 , the present invention provides a thin hinge 100 with variable torque. The thin hinge 100 includes a base 10 , a rotating group 20 and a torque providing group 30 . The base 10 forms an installation space 11 , and the base 10 may be an integrally formed structure, or may be composed of a plurality of components. In one embodiment, the base 10 is composed of a base 12 and a frame 13 , and the base 12 and the frame 13 together define the installation space 11 .

The rotating group 20 is disposed in the installation space 11 . The rotating group 20 includes two first arc-shaped members 21 arranged at intervals, and a second arc-shaped member 22 located between the two first arc-shaped members 21 . The second arc-shaped member 22 is located between the two first arc-shaped members 21. The second arc-shaped member 22 acts as the driver when the rotating group 20 rotates. The second arc-shaped member 22 drives the two arc-shaped members during the rotation process. The first arc-shaped member 21, and the two first arc-shaped members 21 are in a co-moving relationship, and the two first arc-shaped members 21 can be driven by the second arc-shaped member 22 at the same time. An accommodating groove 211 is formed on each of the arc-shaped members 21 , and the rotating group 20 has a connecting column 24 disposed in the two accommodating grooves 211 and connecting the two first arc-shaped members 21 . Accordingly, the second arc-shaped member 22 and the two first arc-shaped members 21 of the present invention can be opened and closed relative to the base 10 in sequence based on the rotation angle of the rotating group 20 . In addition, the two first arc-shaped members 21 and the second arc-shaped members 22 have arc surfaces 212 and 221 respectively, and the plurality of arc surfaces 212 and 221 have different curvatures.

On the bearing, the torque providing group 30 is disposed in the installation space 11 , and the torque providing group 30 includes a pivot shaft 31 disposed on the base 10 , a friction plate 32 disposed on the pivot shaft 31 , and at least one The torsion spring 33 provided on the base 10 . More specifically, the pivot shaft 31 penetrates the base 10 .

The torsion spring 33 is disposed corresponding to the friction plate 32. Since the friction plate 32 may rotate along with the pivot shaft 31, the torsion spring 33 can suppress the friction plate 32 and restrain the friction plate 32 from displacement. The spring 33 makes the friction plate 32 contact different positions of the plurality of arc surfaces 212 and 221 when the two first arc-shaped members 21 and the second arc-shaped members 22 rotate in sequence, so as to make the friction plate 32 change the torque provided.

Continuing from the above, referring back to FIGS. 1 to 7 , the embodiment of the thin hinge 100 will now be described. Assuming that the thin hinge 100 is in an open state initially, the second arc-shaped member 22 does not rotate relative to the base 10 . When the thin hinge 100 is to be closed, the second arc-shaped member 22 is forced to rotate relative to the base 10 , the second arc-shaped member 22 rotates with the arc of the second arc-shaped member 22 during the rotation process The surface 221 generates friction with the friction plate 32 , and at this moment, the friction plate 32 provides a first torque value to the rotating group 20 . When the second arc-shaped member 22 rotates to a certain angle, the second arc-shaped member 22 drives the two first arc-shaped members 21 , so that the two first arc-shaped members 21 also rotate relative to the base 10 . At this time, the rotating group 20 uses the two arc surfaces 212 of the two first arc-shaped members 21 to generate friction with the friction plate 32 , so that the friction plate 32 provides a second torque value to the rotating group 20 . In addition, since the curvatures of the arc surface 221 of the second arc-shaped member 22 and the two arc-shaped surfaces 212 of the two first arc-shaped members 21 are different, the second torque value is different from the first torque value, and further The torque value that the rotating group 20 bears is changed. When the thin hinge 100 is returned, the rotating group 20 generates friction with the friction plate 32 through the two arc surfaces 212 of the two first arc members 21 and the arc surfaces 221 of the second arc member 22 in sequence. After the rotating group 20 changes the contact position with the friction plate 32 , the torque provided by the friction plate 32 is converted from the second torque value to the first torque value.

It can be seen from the above that the friction plate 32 of the present invention is sleeved on the pivot shaft 31, the thin hinge 100 uses the torsion spring 33 to press the friction plate 32, and at the same time, through the setting of the friction plate 32 and the plurality of arc surfaces 212 and 221, The plurality of arc surfaces 212, 221 change the position of contact with the friction plate 32 during the rotation of the two first arc members 21 and the second arc member 22, so that the friction plate 32 provides different torques, thereby The present invention improves the problem that the conventional hinge is limited by the fixed torsion during the opening and closing process, which affects the rotation of the implemented object.
