1. Field of the Invention
The present invention relates to a biaxial pivoting mechanism, and more particularly, to a biaxial pivoting mechanism having small size volume and easy structure and an electronic device thereof.
2. Description of the Prior Art
A conventional biaxial pivoting mechanism is used as a central pivoting mechanism of a tablet notebook computer. A panel module of the tablet notebook computer can be unfolded relative to a host module, so that the user inputs information on a keyboard of the host module, and the information is displayed on the panel module. The above mentioned mode of the tablet notebook computer is called as a notebook computer mode. The panel module can also be rotated relative to the host module about 180 degrees and be folded to completely cover the host module, so that the user inputs information via a touch panel of the panel module, by which mode of the tablet notebook computer is called a tablet computer mode. Volume of the conventional biaxial pivoting mechanism is huge. Two ends of a connecting cable passes through a casing of the pivot to respectively connect to the panel module and the host module, so that the conventional biaxial pivoting mechanism has weak structural strength due to the imperfect casing. Besides, the casing of the pivot cannot cover the plurality of connecting cables, the connecting cables is hard to be arranged, and is abraded easily in rotation. Thus design of a pivoting mechanism having small-size volume, covering the cables preferably without abrasion, and capable of rotating in a multi-axial manner is an important issue of the mechanism industry.
