2. Description of the Related Art
A conventional electronic device utilizing global positioning system (GPS) includes a host, an antenna and a uniaxial hinge. The antenna is pivotally connected to the host via a uniaxial hinge, so that the conventional antenna can rotate around a straight line as the axis for enabling the antenna to be adjusted to an appropriate direction and angle capable of receiving a positioning signal transmitted by a satellite system.
When the electronic device utilizing GPS is installed in a vehicle, the driver can be informed of the current position by the electronic device utilizing GPS, which can further provide the driver with the route and navigation.
However, the best direction and angle of signal reception of an antenna may change when the electronic device is positioned in different places. Moreover, the conventional antenna can only rotate around a straight line as the axis with respect to the host, so that the movements and directions of the antenna are severely restricted and that the driver may be unable to adjust the antenna to the best direction and angle of signal reception. Thus, the conventional electronic device utilizing GPS might have poor signal reception and fail to position the vehicle. Consequently, the positioning and navigating functions are incapacitated, severely affecting the practicality of the electronic device utilizing GPS.

The invention achieves the above-identified object by providing another electronic device utilizing GPS. The electronic device includes a host, an antenna and a hinge. The hinge pivotally connects the host and the antenna for enabling the antenna to rotate with respect to the host three-dimensionally.

The main concept of the invention is to pivotally connect the host and the antenna of the electronic device utilizing GPS by a hinge which can be rotated in three dimensions, so that the antenna rotates around at least a first straight line and a second straight lire as axes, largely increase the scope and range of movement of the antenna for enabling the antenna to receive a positioning signal transmitted by a satellite system in more directions and wider angles. By doing so, the invention resolve the problem of poor signal reception of the conventional electronic device utilizing GPS whose antenna can only rotate around a straight line as the axis. Embodiments of the electronic device utilizing GPS of the invention are exemplified below with accompanied drawings.
Referring to both FIGS. 1A˜1B, two three-dimensional diagrams of the electronic device utilizing GPS according to the preferred embodiment of the invention are shown. In FIGS. 1A˜1B, the electronic device utilizing GPS 100 includes a host 102, an antenna 104 and a hinge 110. The hinge 110 pivotally connects the host 102 and the antenna 104, so that the antenna 104 rotates with respect to the host 102 three-dimensionally, largely transcending the restraint imposed on the conventional antenna which can only rotate with respect to the host via a uniaxial hinge and enhancing the practicality of the electronic device utilizing GPS.
