Abstract

A portable electronic device including a first body, a second body, a stand, and a hinge structure is provided. The stand has a first pivot part and a second pivot part opposite to the first pivot part, wherein the first pivot part is pivotally connected to the first body, and the second body is pivotally connected to the second pivot part. The hinge structure includes a first bracket secured to the second body, a second bracket secured to the second pivot part of the stand, a first movable base, a first shaft secured to the first bracket and pivoted to the first movable base, a second movable base, a second shaft secured to the first movable base and pivoted to the second movable base, and a sliding shaft fixed to the second movable base and slidably connected to the second bracket.

First claim

What is claimed is:

1 . A portable electronic device, comprising:
a first body; a second body; a stand, has a first pivot part and a second pivot part opposite to the first pivot part, wherein the first pivot part is pivotally connected to the first body, and the second body is pivotally connected to the second pivot part; and a hinge structure, comprising:
a first bracket, secured to the second body;
a second bracket, secured to the second pivot part of the stand;
a first movable base;
a first shaft, secured to the first bracket and pivoted to the first movable base;
a second movable base;
a second shaft, secured to the first movable base and pivoted to the second movable base; and
a sliding shaft, fixed to the second movable base and slidably connected to the second bracket, wherein the first bracket is rotatable about two parallel axes relative to the second bracket and the two parallel axes respectively passes through the first shaft and the second shaft.

2 . The portable electronic device according to claim 1 , wherein the second shaft is arranged between the first shaft and the sliding shaft.

3 . The portable electronic device according to claim 1 , wherein a torsion of the first shaft is greater than a torsion of the second shaft.

4 . The portable electronic device according to claim 1 , wherein the second bracket has a sliding slot, and the sliding shaft is slidably arranged in the sliding slot.

5 . The portable electronic device according to claim 4 , wherein the sliding slot extends toward the second shaft.

6 . The portable electronic device according to claim 4 , wherein the sliding slot has a first route end and a second route end, and the second route end is arranged between the first shaft and the first route end, when the first bracket and the first movable base are turned over relative to the second movable base and the second bracket through the second shaft, the second movable base slides relative to the second bracket and the sliding shaft slides from the first route end to the second route end, then, the first movable base and the second movable base remain stationary, and the first bracket is turned over relative to the first movable base through the first shaft.

7 . The portable electronic device according to claim 1 , wherein the first movable base has a sliding protrusion part arranged around the second shaft, and the sliding protrusion part is slidably connected to the second bracket, wherein a sliding direction of the sliding protrusion part is not parallel to a sliding direction of the sliding shaft.

8 . The portable electronic device according to claim 7 , wherein the sliding protrusion slides synchronously with the sliding shaft.

9 . The portable electronic device according to claim 7 , wherein the second bracket has a sliding slot and a guide slot on one side of the sliding slot, the sliding shaft is slidably arranged in the sliding slot, and the sliding protrusion part is slidably arranged in the sliding slot.

10 . The portable electronic device according to claim 9 , wherein the sliding slot is not parallel to the guide slot.

11 . The portable electronic device according to claim 1 , wherein the first shaft is unable to slide with respect to the first bracket.

12 . The portable electronic device according to claim 1 , wherein the second movable base is unable to rotate with respect to the sliding shaft.
