a) Field of the Invention
The present invention relates to a global positioning system, and more particularly to a direction indication device of a global positioning system, which produces light of direction indication such that a driver can be indicated with the driving direction through the indication light.
b) Description of the Prior Art
In modern life, convenience is one of the rather important quests; therefore, a lot of electronic devices are emerging continuously, such as a global positioning system or a cellular phone which can add a lot of conveniences to human lives.
Following progressiveness of technologies, many electronic products that can increase conveniences in lives are advanced continuously too, and the technology of satellite navigation also progresses significantly that functions of the products are improved continuously by vendors of the satellite navigation devices to attract consumers, including the improvement in a quality of navigation, an operation interface, a display screen and a size, as well as a design toward a lightweight and compact satellite navigation device.
However, when using the global positioning system, a lot of drivers will install the global positioning system on a fixing bracket which is located at a place where the global positioning system is easy to be seen; therefore navigation information displayed on a screen of that global positioning system can be directly seen when driving, such that the drivers can be aware of a direction or a position to turn. In addition, the global positioning system is also provided with a voice system to inform the direction or position to turn in voice, thereby achieving a function for navigating through the voice system and the navigation information on the screen.
Nevertheless, in using the aforementioned global positioning system, following problems and shortcomings actually exist to be improved.
The driver has to completely put his or her eyesight on the screen of the global positioning system to be aware of the direction or position to turn. Therefore, when seeing the screen, attention of driving will be decreased easily, this is easy to result in a danger of driving at a same time. Moreover, when an ordinary driver is driving, he or she will usually play music or listen to broadcasting; therefore, when the driver needs to know the direction or position to turn from the voice system, the sound of voice device will come out along with the sound of music or broadcasting, this further prohibits the driver from accurately knowing the direction informed by the voice device.
Accordingly, how to solve the aforementioned problems and shortcomings of the prior art is an aim of improvement with research and development by the present inventor and related vendors.
The primary object of the present invention is to provide a direction indication device of a global positioning system, wherein a host of the global positioning system is provided with a direction indication module which is connected to a navigation module by a signal, with the navigation module producing a navigation signal to a display panel, the direction indication module producing an indication signal according to the navigation signal, and the indication signal being displayed on an indication unit. By the aforementioned technologies, the problems existing in the conventional global positioning system that when the driver has to totally concentrate on the screen of the global positioning system, the attention of driving will be decreased easily, or that when the direction or position to turn needs to be known from the voice system, the direction informed by the voice device cannot be known accurately due to that the sound of voice device is easily interrupted by other sound, can be solved, thereby achieving the practicability and progressiveness that the driver can be indicated with the direction through indication light produced by the indication unit.
Another object of the present invention is to provide a direction indication device of a global positioning system, wherein the indication unit includes at least one illumination element, with each illumination element being installed at a proper spacing and conducting indication of all direction according to the direction indicated by the navigation signal, thereby allowing the driver to be clearly aware of the direction indication through the indication light produced by the indication unit.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

On the other hand, after the indication unit 31 has received a right-turn indication signal 241, an illumination element 311 representing the right-turn will produce light, such that the driver can see the light of that illumination element 311 while watching at a road condition, which further enables the driver to know the direction informed by the display panel 22 without watching at the global positioning system 1.
Referring to all the drawings, the present invention is actually provided with following advantages in comparison with the prior art:
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
