Abstract

A hinge mechanism includes first torsion shafts, a first torsion sleeve, second torsion shafts, a second torsion sleeve, a first fixing assembly, a second fixing assembly and a third fixing assembly. The first torsion sleeve is sleeved on the first torsion shafts to link the first torsion shafts. The second torsion sleeve is sleeved on the second torsion shafts to link the second torsion shafts. The first and the second torsion sleeves interfere with each other, so the adjacent first and second torsion shafts drive each other to move. The first fixing assembly is engaged with the adjacent first and second torsion shafts respectively. The second fixing assembly is engaged with the first torsion shaft away from the second torsion shafts. The third fixing assembly is engaged with the second torsion shaft away from the first torsion shafts. The first, second and third torsion shafts interfere with each other.

Claims

1. A hinge mechanism, adapted to be pivotally connected between a first body and a second body, comprising:

a plurality of first torsion shafts;

a first torsion sleeve sleeved on the first torsion shafts, so as to link the first torsion shafts;

a plurality of second torsion shafts;

a second torsion sleeve sleeved on the second torsion shafts, so as to link the second torsion shafts, the first torsion sleeve and the second torsion sleeve interfering with each other, such that the first torsion shaft and the second torsion shaft adjacent to each other drive each other to move;

a first fixing assembly engaged with the first torsion shaft and the second torsion shaft adjacent to each other;

a second fixing assembly engaged with the first torsion shaft away from the second torsion shafts; and

a third fixing assembly engaged with the second torsion shaft away from the first torsion shafts, the first fixing assembly disposed between the second fixing assembly and the third fixing assembly and interfering therewith, so as to drive one another to move.

2. The hinge mechanism as claimed in claim 1, wherein each of the first torsion shafts comprises a first locking end, each of the second torsion shafts comprises a second locking end, the first fixing assembly is engaged with the corresponding first locking end and the corresponding second locking end, the second fixing assembly is engaged with the corresponding first locking end, and the third fixing assembly is engaged with the corresponding second locking end.

3. The hinge mechanism as claimed in claim 2, wherein the second fixing assembly comprises a second fixing element and a second cover element, the second fixing element comprises at least one second locking hole engaged with the first locking end of the first torsion shaft furthest from the second torsion shafts, the second cover element covers the second fixing element, the third fixing assembly comprises a third fixing element and a third cover element, the third fixing element comprises at least one third locking hole engaged with the second locking end of the second torsion shaft furthest from the first torsion shafts, the third cover element covers the third fixing element.

4. The hinge mechanism as claimed in claim 3, wherein the first fixing assembly comprises:

a first fixing element comprising a plurality of first locking holes respectively engaged with the first locking end and the second locking end of the first torsion shaft and the second torsion shaft adjacent to each other; and

a first cover element covering the first fixing element and the first locking holes, wherein the first cover element interferes with and the second cover element and the third cover element, such that the first fixing assembly, the second fixing assembly and the third fixing assembly drive one another to move.

5. The hinge mechanism as claimed in claim 4, wherein the first cover element comprises a plurality of driving inclined surfaces contacting the second cover element and the third cover element, the driving inclined surfaces are parallel to each other, when the second fixing assembly rotates relative to the first fixing assembly, the second cover element interferes with the corresponding driving inclined surface to drive the first cover element to rotate, the third cover element interferes with the corresponding driving inclined surface to drive the third cover element to rotate.

6. The hinge mechanism as claimed in claim 1, further comprising a plurality decorative element connecting to the first fixing assembly, the second fixing assembly and the third fixing assembly respectively to cover the first torsion shafts, the second torsion shafts, the first torsion sleeve and the second torsion sleeve.

7. The hinge mechanism as claimed in claim 6, further comprising:

a first connecting element connecting the first body and having a first linking end, wherein the decorative element connecting the second fixing assembly covers and connected to the first linking end; and

a second connecting element connecting the second body and having a second linking end, wherein the decorative element connecting the third fixing assembly covers and connected to the second linking end, such that the first body drives the first linking end so as to rotate relative to the second body through the hinge mechanism.

8. The hinge mechanism as claimed in claim 1, wherein the first torsion sleeve comprises a first protrusion, the second torsion sleeve comprises a second protrusion, when the first torsion sleeve rotates relatively to the second torsion sleeve, the first protrusion interferes with the second protrusion to drive the second torsion sleeve to rotate.

9. A portable electronic device, comprising:

a first body;

a second body;

the hinge mechanism as claimed in claim 1 pivotally connected between the first body and the second body, such that the first body is capable of rotating relatively to the second body through the hinge mechanism.

10. The portable electronic device as claimed in claim 9, wherein the first body comprises a display, and the second body comprises a keyboard module.
