Abstract

A torque hinge module including a rotating element and a torque assembly is provided. The torque assembly rotatably sleeves the rotating element to generate torque. One of the rotating element and the torque assembly has a first bearing surface, and the other one has a second bearing surface and a third bearing surface corresponding to the first bearing surface. There is a first included angle between a plane where the second bearing surface is located and a plane where the third bearing surface have is located. A shape of the first bearing surface corresponds to a shape of the second bearing surface and a shape of the third bearing surface. When the rotating element rotates relative to the torque assembly to make the first bearing surface bear against the second bearing surface or the third bearing surface, the torque is reduced.

First claim

What is claimed is:

1. A torque hinge module comprising:
a rotating element; and
a torque assembly rotatably sleeving the rotating element to generate torque,
wherein one of the rotating element and the torque assembly has a first bearing surface, the other one of the rotating element and the torque assembly has a second bearing surface and a third bearing surface corresponding to the first bearing surface, and there is a first included angle between a plane where the second bearing surface is located and a plane where the third bearing surface is located,
wherein a shape of the first bearing surface corresponds to a shape of the second bearing surface, the shape of the first bearing surface corresponds to a shape of the third bearing surface, and when the rotating element rotates relative to the torque assembly to make the first bearing surface bear against the second bearing surface or the third bearing surface, the torque is reduced,
wherein the first bearing surface is a plane, the second bearing surface is a plane, and the third bearing surface is a plane,
wherein the rotating element has a shaft portion, a cross section is defined at a part of the shaft portion, where the part of the shaft portion does not have the first bearing surface, the second bearing surface, and the third bearing surface, the cross section is perpendicular to a central axis of the shaft portion, and a circle is defined by an outermost periphery of the cross section of the shaft portion,
wherein when the rotating element rotates and the first bearing surface bears against the second bearing surface, orthogonal projections of the first bearing surface and the second bearing surface on the cross section are located in the circle,
wherein when the rotating element rotates and the first bearing surface bears against the third bearing surface, orthogonal projections of the first bearing surface and the third bearing surface on the cross section are located in the circle,
wherein the other one of the rotating element and the torque assembly further has a fourth bearing surface corresponding to the first bearing surface, there is a second included angle between the plane where the second bearing surface is located and a plane where the fourth bearing surface is located, and when the rotating element rotates relative to the torque assembly to make the first bearing surface bear against the fourth bearing surface, the torque is reduced.

2. The torque hinge module as claimed in claim 1 , wherein the first included angle is 90 degrees.

3. The torque hinge module as claimed in claim 1 , wherein the rotating element has the first bearing surface, and the torque assembly has the second bearing surface and the third bearing surface.

4. The torque hinge module as claimed in claim 3 , wherein the torque assembly comprises:
a first torque element having the second bearing surface; and
a second torque element having two third bearing surfaces, wherein the first bearing surface is adapted for bearing against the corresponding third bearing surface.

5. The torque hinge module as claimed in claim 1 , wherein the torque assembly has the first bearing surface, and the rotating element has the second bearing surface and the third bearing surface.

6. The torque hinge module as claimed in claim 5 , wherein the torque assembly comprises two torque elements, and each of the torque elements has the first bearing surface.

7. The torque hinge module as claimed in claim 1 , wherein a number of the rotating elements is two, the torque assembly is rotatably sleeved on the two rotating elements, and the torque hinge module further comprises:
two brackets fixed to the rotating elements; and
a synchronization mechanism connected between the two rotating elements, so that the two rotating elements pivot synchronously.

8. The torque hinge module as claimed in claim 1 , further comprising:
two brackets, wherein one of the two brackets sleeves the torque assembly, and the other one of the two brackets is fixed to the rotating element.
