Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of Invention 
         [0002]    The invention relates to an electronic system with satellite navigation and a display thereof. That is, the invention relates to an electronic device having a display body with a large size such as a notebook computer and, more particularly, to an electronic system with satellite navigation from which a display may be detached and used as a satellite navigation system independently and the display thereof. 
         [0003]    2. Description of the Related Art 
         [0004]    It is a trend that people like to go around for travelling on holidays. A vehicle navigation with global satellite positioning and navigation software may prevent people from getting lost on the road. Thus, it becomes a necessary object when people go out for travelling. A global positioning system (GPS) is a medium earth orbit satellite navigation system. It may provide precise location, velocity and accurate time standard in most areas of the global surface (98 percent). Cooperating with the navigation software, the GPS may provide an accurate route for a driver to prevent the driver from getting lost or detouring. 
         [0005]    However, the volume of the current satellite navigation device is designed to be small for facilitating the carrying. Relatively, the display body may not be big. Therefore, although it is convenient for carrying or keeping, it is not convenient for the driver to operate. Especially, it is not easy to read or recognize the characters on the satellite navigation device. 
         [0006]    The general satellite navigation device has a phonic navigation function. A driver may preset a destination and requirement (such as the shortest distance, the fastest speed and so on). Then, when the vehicle is near a crossing, the phonic navigation device indicates to the driver that he should go straight or turn. However, before the destination is set, the driver also has to operate the satellite navigation device towards the mini-sized display body, and recognizing the characters is still a big problem. In addition, the user does not have definite destination every time. In some cases, the user watches the satellite navigation device and drives meanwhile to recognize the way. At that moment, if the display body is too small, the user may go out his way, lose or detour, and more seriously, the safety of the driver when driving a vehicle is affected. 
         [0007]    In another aspect, although a satellite navigation module is disposed in some advanced notebook to be a navigation device temporarily. However, the volume of the notebook is big, and the notebook is not convenient to dispose in front of the driver&#39;s seat. Generally, it is held by a passenger sitting beside the driver. However, there is no passenger sitting next to the driver every time. If it is put on a seat next to the driver, it is not convenient for the driver to watch. In addition, when the notebook computer is operated, the hard disc also works. It is not proper to dispose the computer on the vehicle. Once the road is uneven or the car brakes emergently, the system is easy to be down, and if it is serious, the hard disk drive may be damaged for scratch. 
       BRIEF SUMMARY OF THE INVENTION 
       [0008]    An electronic system having satellite navigation disclosed in the invention includes a main body and a display. The display is disposed on the main body to allow a user to operate normally. The display also may be detached from the body of the electronic device. The GPS module disposed inside the display allows the driver to use as a satellite navigation device. Generally, the electronic system has a larger display body, and this may conquer the problem that the display body is so small that the characters cannot be seen clearly or they are not easy to be recognized. 
         [0009]    In another aspect, to make the user dispose and operate the display body on a vehicle easily, the invention further includes a carrying base to allow the display to be disposed on after it is detached. This facilitates the disposing of the display on the vehicle. The display body of the display further includes a connecting port and a control circuit. The connecting port is used to connect the display to the main body, and thus, an electrical connection is formed to receive signal from the main body and display the signal. Thus, the user can operate the electronic system normally. The control circuit controls to enable the GPS module after the display is detached, and this allows the user to use the GPS module separately and operate the function of the GPS module directly. The display has a battery on its own to provide power for it, and the battery also may be designed to be disposed in the carrying base. Cooperating with a vehicle charging connecting wire, the battery is charged and provides power continually. 
         [0010]    These and other features, aspects and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0018]      FIG. 1  is a schematic diagram showing an electronic system  10  disclosed in the invention. As shown in  FIG. 1 , according to the electronic system having satellite navigation disclosed in the invention, the electronic system  10  includes a main body  11  and a display  20 . The display  20  further includes a display body  25  and a GPS module  23 . The display body  25  further has a connecting port  21  and a control circuit  22 . Generally, the electronic system  10  is just used as a common portable electronic device. The display  20  is connected to the main body  11  via the connecting port  21 . The control circuit  22  controls the display  20  to display the content executed by the main body  11  and the data of the main body  11  according to a received signal to allow the user to operate the electronic system  10  normally. 
         [0019]    Specially, a GPS module  23  is added to the display  20  and controlled by the control circuit  22 . Since the main body  11  has a central processing unit (CPU), a hard disk drive (HDD) and other non-shockproof components (not shown) inside, it is not adapted for being disposed on a moving vehicle when it is operated. In addition, the main body  11  has a certain volume, and the vehicle has no proper position to dispose the main body  11 . Therefore, the display  20  is designed to be detachable. In other words, the display  20  may be detached from the main body  11 . After the display  20  is detached, the control circuit  22  enables the GPS module  23 . Thus, the display  20  may be disposed on the vehicle separately to allow the driver to operate the display  20  directly, and the related satellite navigation function is performed. The data of the GPS module  23  is displayed through the display body  25 . 
         [0020]    Generally, the display body  25  of the electronic system  10  has no adjusting buttons, which is not similar to a desktop display. Once it is detached, there is no buttons to operate the display. Therefore, part of the display body  25  is designed to be a touch panel to meet the user&#39;s habit of operating the satellite navigation device. Therefore, even though the display body  25  is detached from the main body  11 , the user also can directly operate the display body  25  on the touch panel. If the electronic system  10  has a touch pen, the user can input data with the touch pen. In another aspect, the display  20  may be designed to sense whether the connecting port  21  is connected to the main body  11  by the control circuit  22 . If the display  20  is sensed to be detached from the main body  11 , the control circuit  22  directly turn-on the GPS module  23 . A starting button or an operation button having the satellite navigation function also may be additionally disposed on the display  20 , but the manufacturing cost increases slightly. 
         [0021]    In another aspect, the display  20  of the electronic system  10  generally has a big size, and it may be used as a satellite navigation device. Therefore, when the display  20  is detached from the main body  11 , it is not easy to dispose the display  20  on the vehicle separately.  FIG. 2A  is a schematic diagram showing the electronic system having the satellite navigation cooperating with a carrying base  30 . After the display  20  is detached, it may be disposed on the carrying base  30 , and then the display  20  and the carrying base  30  are both disposed in the vehicle. Therefore, the carrying base  30  needs a larger supporting area at the bottom to bear the weight of the display  20 . To provide power to the GPS module  23 , the display  20  further includes a battery  24 . After the display  20  is detached, the GPS module  23  also may be operated. Considering that the electric quantity of the battery  24  is limited, a vehicle charging connecting wire is additionally disposed at the carrying base  30 . The vehicle charging connecting wire  31  is connected to the connecting port  21  of the display  20 , and the battery  24  is charged when it is used in the vehicle. 
         [0022]    In another aspect, as shown in  FIG. 2B , the power supply also may be designed to be disposed on the carrying base  30 . That is, the carrying base  30  has a battery  32  on it. The connecting port  21  of the display  20  is used to provide power. The starting mode herein also may be designed to be the mode that when the control circuit  22  senses that the connecting port  21  is connected to the carrying base  30 , the GPS module  23  is turn-on automatically. 
         [0023]      FIG. 3A  and  FIG. 3B  are used to illustrate the external structure of the electronic system having the satellite navigation disclosed in the invention. As shown in  FIG. 3A  and  FIG. 3B , they are schematic diagrams showing the electronic system having the satellite navigation disclosed in the invention. 
         [0024]    The electronic system  70  includes a display  40  and a main body  50 . The display  40  has a display body  45  and is disposed at the main body  50 . The bottom of the display  40  has a base  42  pivotally connected to the bottom of the display body  45  of the display  40 . Therefore, the display  40  may be rotated relative to the main body  50  to be open or closed. The base  42  has two tenons  41  on it, and the main body  50  has two corresponding connecting holes  51  to allow the base  42  to be inserted in the main body  50  and detached from the main body  50  easily. The control circuit, the battery and other components included in the above display  40  may be disposed inside the base  42 , and they also may be disposed on other parts of the display  40 . 
         [0025]    As shown in  FIG. 4 , the connecting port  43  of the display  40  is also disposed on the bottom of the base  42 . The main body  50  has a corresponding connecting base  52  to allow the connecting port  43  to contact the connecting base  52  and electrically connected to the main body  50  to receive the signal from the main body  50 . Thus, the data of the main body  50  is displayed by the display  40 . Since the display  40  is designed to be detachable, to avoid the wear and damage of the connecting port  43  caused by frequent inserting and pulling, the connecting port  43  is preferably a pogo pin connector. 
         [0026]    In another aspect, considering that it is not firm to insert just a tenon  41  to a connecting hole  51 , a screw  71  also may be used to increase the firmness, as shown in  FIG. 5 . The screw  71  may be inserted in a screwed hole  53  at the back of the main body  50  to be locked with the inserted tenon  41 . The screwed hole  53  communicates with the connecting hole  51 . This further increases the fastening firmness. The screw  71  herein is only an embodiment, and the fixing mode may adopt other modes such as bolt fastening. The fixing mode is also an embodiment, and it is not used to limit the scope of the invention. 
         [0027]    As shown in  FIG. 6A  and  FIG. 6B , they are schematic diagrams showing the electronic system having the satellite navigation disclosed in the invention, in which the display is connected to the carrying base. 
         [0028]    After the display  40  is detached from the main body  50 , it provides related satellite navigation functions for the user independently. However, to facilitate the operation of the satellite navigation functions when the display is disposed on the vehicle, the carrying base  60  is designed to make it convenient for the user to operate the display  40  on the vehicle. The carrying base  60  has an accommodating room  61 , and the accommodating room  61  is designed to cooperate with the shape of the bottom of the display  40  approximately to accommodate the bottom of the display body  45  of the display  40  properly. In addition, the accommodating room  61  has two connecting holes  62 , and they are corresponding to the tenons  41  of the display  40  to allow the tenons  41  to be inserted in the connecting holes  62  to fix the display  40 . However, to increase the firmness of the combination, a fastener  64  is disposed at a front edge of the accommodating room  61  of the carrying base  60 . The bottom of the display  40  has a corresponding slot  44 . When the tenons  41  of the display  40  are inserted in the connecting holes  62 , the fastener  64  is fastened in the slot  44  at the bottom of the display  40  to increase the firmness. 
         [0029]    In another aspect, the display  40  has a larger size, and the above connecting mode may not be enough. Especially, the display  40  is inclined to be sheet-shaped, and it is easy to rotate or overturn. Thus, an edge of the accommodating room  61  of the carrying base  60  has a protrudent block portion  65  to prevent the display  40  from rotating and being detached from the carrying base  60 . Known from the embodiment above, the accommodating room  61  also may have a connecting base  63  connected to the connecting port  43  of the display  40  (as shown in  FIG. 4 ). Since the display  40  is disposed on the vehicle, the bottom of the carrying base  60  has an extending portion  66  extending outward to increase the area of the bottom of the carrying base  60 . This makes the display  40  disposed on the vehicle firmly, and the danger of overturning may be avoided when the vehicle bumps. 
         [0030]    In another aspect, if the connecting mode that the tenons  41  are inserted into the connecting holes  62  cannot make the combination firm, a screw  72  may be used to increase the firmness. As shown in  FIG. 7 , the screw  72  may be inserted in the screwed hole  67  at the back of the accommodating room  61  of the carrying base  60  to be locked with the inserted tenon  41 . The screwed hole  67  communicates with the connecting hole  62 . This further increases the fastening firmness. The screw  72  herein is only an embodiment, and the fixing mode may be other modes such as bolt fastening mode which is easier to insert and pull. The fixing mode is also an embodiment, and it is not used to limit the scope of the invention. 
         [0031]    A general ultra-mobile portable computer on the market is not convenient to process the functions such as a navigation function or a document task for it is mini in size. However, in the invention, the display may be detached from the main body to be used separately. If a user wants to process the document task, he or she may combine the display and the main body together. Thus, he or she can process general operations on the electronic device. When the user wants to use the navigation function, he or she may detach the display to use a GPS module function without worrying the damage of the components in the main body due to the uneven road. In addition, the display body is generally big in size, and this makes the image and character of the navigation system easy to be recognized. 
         [0032]    Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, the disclosure is not for limiting the scope of the invention. Persons having ordinary skill in the art may make various modifications and changes without departing from the scope and spirit of the invention. Therefore, the scope of the appended claims should not be limited to the description of the preferred embodiments described above.
