Portable electronic device

The present invention relates to a portable electronic device, and more particularly to a portable electronic device having a pivoting mechanism.

Currently, notebook computers on the market have a pivoting mechanism (for example, a hinge structure) for pivoting the upper cover (with a screen) of the notebook computer with respect to the main body (with a keyboard). However, in the current general design, in the closed state, the upper cover of the notebook computer does not easily fit the upper surface of the main body, thereby causing an increase in the overall thickness of the notebook computer in the closed state. Moreover, in the conventional design, the angle between the screen of the notebook computer and the keyboard is 180 degrees, which will limit the application of the notebook computer.

The present invention provides a portable electronic device for solving the problems of the prior art, including a first component, a first pivoting unit, a second component, and a second pivoting unit. The first component includes a first surface and a second surface, the first surface being opposite the second surface. The first pivoting unit is disposed on one side of the first component, wherein the first pivoting unit includes a gear and a first shaft, and the gear rotates around the first axis. The second component includes a third surface and a fourth surface, the third surface being opposite the fourth surface. The second pivoting unit is disposed on a side of the second component, wherein the second pivoting unit includes a rack extending around a second axis, the gear meshes with the rack, and the gear is along the Cog Moving around the second axis, the rack includes a first end and a second end. When the gear is located at the first end, the angle between the first surface and the third surface is 0 degrees. When the gear is at the second end, the angle between the first surface and the third surface is 360 degrees.

The portable electronic device of the embodiment of the invention is used in In this state, the upper cover (first part) of the notebook can fully fit the upper surface of the main unit (second part), so the overall thickness of the notebook in the closed state can be minimized. Moreover, the angle between the screen of the notebook computer and the keyboard can be arbitrarily adjusted from 0 to 360 degrees, and the notebook computer can be applied in a wider range.
