## Abstract

A hinge structure applied to an electronic device having a first component and a second component is provided. The hinge structure includes a torque hinge and a one-way pivoting mechanism. The torque hinge includes a first base and a first rotation element. The first base connects to the first component. The first rotation element rotatably connects to the first base. The second component pivotally connects to the first rotation element through the one-way pivoting mechanism.

## Claims

### Claim 1

A hinge structure, applied to an electronic device, wherein the electronic device comprises a first component and a second component, the hinge structure comprising:
a torque hinge, comprising a first base and a first rotation element, wherein the first base connects to the first component, and the first rotation element rotatably connects to the first base; and
a one-way pivoting mechanism, wherein the second component pivotally connects to the first rotation element through the one-way pivoting mechanism;
wherein the one-way pivoting mechanism comprises a first shaft and a second shaft, the first shaft connects to the second component, the second shaft links with the first rotation element, the first shaft comprises a first surface, the second shaft comprises a second surface facing the first surface, the first surface comprises a plurality of first oblique tooth structures annularly arranged on the first surface, and the second surface comprises a plurality of second oblique tooth structures annularly arranged on the second surface;
wherein the first oblique tooth structure includes an inclined surface and a straight surface, and the straight surface is parallel to the axial direction of the one-way pivoting mechanism.

### Claim 2 (depends on 1)

The hinge structure according to claim 1, wherein the second shaft movably connects to the first rotation element along an axial direction of the one-way pivoting mechanism.

### Claim 3 (depends on 1)

The hinge structure according to claim 1, wherein the second shaft comprises a sleeve portion, the first rotation element comprises an end portion, and the end portion extends into the sleeve portion.

### Claim 4 (depends on 3)

The hinge structure according to claim 3, wherein the sleeve portion comprises a slide groove, the end portion comprises a protruding element, and the protruding element is slidably disposed in the slide groove.

### Claim 5 (depends on 1)

The hinge structure according to claim 1, further comprising an elastic element, disposed between the first rotation element and the second shaft.

### Claim 6 (depends on 1)

The hinge structure according to claim 1, wherein the first component is a host part, and the second component is a screen part.
