Abstract
Claims
1. A hinge module, comprising: A support frame; A pivot is rotatably mounted on the bracket; And multiple clips are assembled on the bracket, each clip having a root and a clamping portion extending from the root, the root being assembled on the bracket, the clamping portion having an open annular profile, the clamping portion being fitted onto and contacting a portion of the rotating shaft to define a frictional force, and the frictional force changing according to the relative rotation angle between the clamping portion and the rotating shaft.
2. The hinge module as claimed in claim 1, wherein the open annular profile has an inner edge and an outer edge, a notch is formed at the adjoining point of the inner edge and the outer edge, the inner edge abuts against the pivot, and a relative width between the outer edge and the inner edge gradually increases from the notch toward the root.
3. The hinge module as claimed in claim 2, wherein when the clip is not holding the pivot, the outline of the outer edge and the outline of the inner edge are two circles with their centers offset, and the center of the outline of the outer edge is located on a rotation axis of the pivot.
4. The hinge module as claimed in claim 2, wherein when the clip holds the pivot, the center of the outer edge profile and the center of the inner edge profile are both located on the axis of rotation of the pivot.
5. The hinge module as claimed in claim 2, wherein the inner edge is asymmetrically clamped relative to a rotation axis of the pivot.
6. The hinge module as claimed in claim 1, wherein the clips are detachably assembled to the bracket and stacked together.
7. The hinge module as claimed in claim 1, wherein the pivot has a clearance portion to reduce the frictional force as an inner edge of the clamping portion passes through the clearance portion.
8. The hinge module as claimed in claim 7, wherein the clearance portion is a chordal section of the pivot, the open annular profile has an inner edge and an outer edge, a notch is formed at the adjoining point of the inner edge and the outer edge, and the chordal section moves away from the notch and to the inner edge to reduce the contact area between the inner edge of the clamping portion and a cylindrical surface of the pivot.
9. The hinge module of claim 7, wherein the pivot includes a cylindrical surface and a tangential surface adjacent to each other, the open annular profile has an inner edge and an outer edge, a notch is formed at the adjacency of the inner edge and the outer edge, a first frictional force exists between the clip and the pivot when the entire inner edge contacts the cylindrical surface and the tangential surface is located at the notch, and a second frictional force exists between the clip and the pivot when a portion of the inner edge contacts a portion of the cylindrical surface and the tangential surface moves away from the notch, the first frictional force being greater than the second frictional force.
10. The hinge module as claimed in claim 1, wherein the bracket has a pair of support rings and a groove between the pair of support rings, the pivot passes through the pair of support rings, the clips are located between the pair of support rings, and a plurality of the roots of the clips are sequentially embedded and stacked in the groove.
11. The hinge module as claimed in claim 10, wherein the root has a protrusion to interfere with the support.
12. The hinge module as claimed in claim 10, wherein the surface of the pivot has an oil groove located between the pair of bearing rings.
