Abstract

A triaxial gear-typed hinge assembly includes a first axle, a second axle, a third axle, a first supporting component, a second supporting component, a first linking component and a second linking component. The first supporting component includes a first gear hinged to the first axle. The second supporting component includes a second gear hinged to the second axle. The first linking component includes a first linking gear and a first tube connected to the first linking gear. The first linking gear is hinged to the third axle and engaged with the first gear, and the first tube is hinged to the second axle. The second linking component includes a second linking gear and a second tube connected to the second linking gear. The second linking gear is hinged to the third axle and engaged with the second gear, and the second tube is hinged to the first axle.

Claims

a first axle;

a second axle parallel to the first axle;

a third axle parallel to the first axle and the second axle;

a first supporting component, comprising a first gear hinged to the first axle;

a second supporting component, comprising a second gear hinged to the second axle;

a first linking component, comprising a first linking gear and a first tube connected to the first linking gear, the first linking gear being hinged to the third axle and engaged with the first gear, the first tube being hinged to the second axle; and

a second linking component, comprising a second linking gear and a second tube connected to the second linking gear, the second linking gear being hinged to the third axle and engaged with the second gear, the second tube being hinged to the first axle.

2. The triaxial gear-typed hinge assembly of claim 1, further comprising:

a first connecting component, two ends of the first connecting component being respectively hinged to the first axle and the third axle; and

a second connecting component parallel to the first connecting component, two ends of the second connecting component being respectively hinged to the second axle and the third axle.

3. The triaxial gear-typed hinge assembly of claim 2, wherein the first supporting component, the second supporting component, the first linking component and the second linking component are buckled between the first connecting component and the second connecting component.

4. The triaxial gear-typed hinge assembly of claim 1, wherein a first contacting portion is disposed on an end of the first axle, the first gear contacts against the first contacting portion, a second contacting portion is disposed on an end of the second axle, the first tube contacts against the second contacting portion, a third contacting portion is disposed on an end of the third axle, and the first linking gear contacts against the third contacting portion.

5. The triaxial gear-typed hinge assembly of claim 4, further comprising:
