Abstract
A rotation velocity adjusting module includes a fixed axle, a rotating component and a rotation velocity adjusting mechanism. The rotating component is pivoted to the fixed axle. The rotation velocity adjusting mechanism includes a driven component, a driving component and a contact component. The driven component is rotatably connected to the rotating component. The driving component and the contact component are disposed on the driven component. When a rotation velocity of the rotating component reaches a threshold value, the driving component drives the driven component to rotate by the change of centrifugal force, so as to switch states of the contact component.
Claims22
A rotation velocity adjusting module, comprising:
- a fixed axle;
- a rotating component, pivoted to the fixed axle and adapted to rotate with the fixed axle as a rotation axis;
- and
- at least one rotation velocity adjusting mechanism, comprising:
- a driven component, rotatably connected to the rotating component and having a first end and a second end;
- a driving component, disposed on the first end;
- and
- a contact component, disposed on the second end, wherein when a rotation velocity of the rotating component reaches a threshold value, the driving component drives the driven component to rotate through a change of centrifugal force, so as to switch a status of the contact component,
- wherein when the rotation velocity of the rotating component is lower than the threshold value, the driven component is positioned at a first status, and when the rotation velocity of the rotating component is greater than the threshold value, the driving component drives the driven component to rotate to a second status through centrifugal force;
- and
- wherein when the driven component is in the first status, the contact component is completely separated from the fixed axle, and when the driven component is in the second status, the contact component is in complete contact with the fixed axle to reduce the rotation velocity of the rotating component.
