The shaft hole 123 is substantially circular and includes a center O, and the distance between the center O and any one of the outer elastic arms 121 is defined as a radius R, and the distance between the center O and the inner edge of the torque adjusting arm 122 is defined. It is an interference distance D0, and the interference distance D0 is smaller than the above radius R. Wherein, the interference distance D0 is preferably 90% to 98% of the above radius R, but the creation is not limited thereto. Furthermore, a central angle of each of the torsion adjusting arms 122 corresponding to the center O of the shaft hole 123 is defined as σ1, and a center angle of the gap G corresponding to the center O of the shaft hole 123 is preferably not more than 30 degrees.

In addition, the position and configuration of the torque adjustment arm 122 can also be adjusted according to the designer's needs, and is not limited to that shown in FIG. For example, in the embodiment, the torque adjustment arm 122 may be configured to divide the space surrounded by the base 11 and the outer elastic arm 121 into a shaft hole 123 and communicate with the shaft hole 123. Two oil sump holes 124, and the two oil sump holes 124 are located on opposite sides of the torque adjustment arm 122, and the shaft holes 123 correspond to the free ends of the torque adjustment arms 122.

Referring to FIGS. 3 to 5, the shaft 2 defines a central axis C, and the outer surface of the shaft 2 has a non-contact surface 21 and a contact surface 22 in the shape of a circular arc. The distance D1 between the contact surface 22 and the central axis C is substantially equal to the radius R, the non The distance D2 between the contact surface 21 and the central axis C is smaller than the interference distance D0.

The shaft 2 is disposed through the shaft hole 123 of the elastic arm unit 12 of each of the torsion sheets 1 , and the central axis C of the shaft 2 in the embodiment is preferably a spring arm substantially overlapping the plurality of torsion sheets 1 . The shaft hole 123 of the unit 12 has a center O such that the contact surface 22 of the shaft 2 abuts against the outer elastic arm 121 of each torsion piece 1 and selectively abuts against the torsion adjusting arm 122 of each torsion piece 1 . It should be noted that the central angle σ1 of the torsion adjusting arm 122 is smaller than the central angle σ2 of the contact surface 22 of the shaft 2, and the central angle σ1 of the torsion adjusting arm 122 is also smaller than the non-contact surface of the shaft 2 .

Wherein, as shown in FIG. 4 and FIG. 7, the torsion adjusting arm 122 of each torsion piece 1 does not contact the shaft 2 in the first position (that is, the torsion adjusting arm 122 faces the non-contact surface 21), The first torsion F1 is generated by rubbing the contact surface 22 of the shaft 2 with the outer elastic arm 121. As shown in FIG. 5 and FIG. 7 , the torsion adjusting arm 122 of each torsion piece 1 partially abuts the contact surface 22 of the shaft 2 in the transition position, so that the contact surface 22 of the shaft 2 rubs against the outer arm. 121 and a part of the torque adjustment arm 122 generate a slow lifting torque F3. As shown in FIG. 6 and FIG. 7, the torsion adjusting arm 122 of each torsion piece 1 completely abuts the contact surface 22 of the shaft 2 in the second position, so that the contact surface 22 of the shaft 2 rubs the outer bullet. The arm 121 and the torque adjustment arm 122 generate a second torque F2. The second torsion F2 is greater than the first torsion F1, and the value of the torsional torsion F3 includes a range that is ramped up from the first torsion F1 to the second torsion F2.

In another angle, in the arm unit 2 and the elastic arm unit 12 of each of the torsion sheets 1 that is worn, the first position (as shown in FIG. 1) is defined as a partial surface of the non-contact surface 21 The torsion adjusting arm 122, and the non-contact surface 21 not facing the torsion adjusting arm 122 has a central angle corresponding to the central axis C of σ3-σ1; the transition position is that the shaft 2 is from the first position Rotating and rotating the angle between σ3-σ1 and σ3; the second position (Fig. 6) is the position where the shaft 2 is rotated by the first position and the rotation angle is greater than σ3.

Therefore, the torsion device 100 disclosed in the embodiment can be coupled to the corresponding shaft 2 through the outer elastic arm 121 of the torsion sheet 1 and the torsion adjusting arm 122 to rotate the shaft 2 relative to the torsion sheet 1 The different positions provide different torques, which in turn enables the torque device 100 to be applied to different devices. For example, when the notebook computer (not shown) of the torque device 100 of the present embodiment is opened by the closed state, the torque device 100 can be designed to provide a low torque corresponding to one-hand opening (eg, the first torque F1). When the touch screen of the notebook computer is opened to a certain angle with respect to the keyboard, the torque device 100 can be designed to provide a high torque required for the touch (eg, the second torque F2).

Moreover, since the shaft 2 and the torsion adjusting arm 122 are frictionally provided by the interference fit, the wear is easily generated. Therefore, the torsion sheet 1 is formed with an oil groove hole 124 capable of providing lubricating oil accommodation, thereby effectively avoiding insufficient lubrication between the shaft 2 and the torsion adjusting arm 122 of the torsion sheet 1, thereby enabling the torsion device 100 to be Provide different torque values steadily.

In addition, the second position of the torsion device 100 of the present embodiment for providing high torque can be determined by the central angle σ3 of the non-contact surface 21 of the shaft 2, so that the designer can design the center of the non-contact surface 21 of the shaft 2 by design.
