Title: Communication module with multiple functions

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to a communication module with multiple functions, and particularly relates to a communication module having a sliding mobile phone structure for reducing signal interference between an embedded module and a GPS module.  
      2. Description of the Related Art  
       FIG. 1  shows a perspective, assembled view of the communication module of the prior art (Referring to U.S. Pat. No. 5,786,789). The communication module of prior art includes a mobile communication device  10  and a GPS (Global Positioning System)  20  connected. The mobile communication device  10  has an antenna module  100  installed therein. The antenna module  100  and the GPS  20  are mated for performing their dual functions as a mobile phone and a GPS.  
      However, the mobile communication device  10  and the GPS  20  are limited by the casing structure of the prior art. Hence, when the communication module of prior art is used, signals of the mobile communication device  10  and the GPS  20  interfere with each other.  
      With the employment of unique considerations and application of theories, and based on several years experience in specialized production of all flexible assembly systems and mechanisms, the inventor has come up with an innovative communication module with multiple functions.  
     SUMMARY OF THE INVENTION  
      The first objective of the present invention is to provide a communication module with multiple functions. The communication module has an embedded antenna module and a GPS module. The embedded antenna module is installed in a top end side of the casing. The GPS module should be installed at the bottom end side of the casing, as far away as possible from the embedded antenna module. Such a placement will assist in the reduction of signal interference between the embedded antenna module and the GPS module.  
      In order to achieve the above objectives, the present invention provides a communication module with multiple functions including a mobile communication device and a GPS module. The mobile communication device has a sliding mobile phone structure, and an embedded antenna module installed at one end side thereof. The sliding mobile phone structure has a top casing and a bottom casing slidably mating with each other. The GPS module is installed at another end side of the mobile communication device. Whereby, when the top casing and the bottom casing are closed the device is used as a “mobile phone”, and when the top casing and the bottom casing are opened the device is used as a “GPS”.  
      It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed. Other advantages and features of the invention will be apparent from the following description, drawings and claims.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
      Referring to  FIGS. 2 and 3 , the present invention provides a communication module with multiple functions including a mobile communication device  1  and a GPS module  2 .  
      The mobile communication device  1  has a sliding mobile phone structure  10 , and an embedded antenna module  12  installed at one end side thereof. The embedded antenna module  12  is a GSM (Global System for Mobile Communications), a PCS (Personal Communication System) or a DCS (Digital Communication System) frequency band. The GPS module  2  is installed at another end side of the mobile communication device  1 .  
      The sliding mobile phone structure  10  has a top casing  100  and a bottom casing  105  slidably mating with each other. The top casing  100  has a first sliding groove  101  formed thereon. The bottom casing  105  has a second sliding groove  106  formed thereon that corresponds to the first sliding groove  101 . Whereby, the first sliding groove  101  and the second sliding groove  106  can be mated with each other for the top casing  100  and the bottom casing  105  to ‘open’ or ‘close’.  
      The embedded antenna module  12  is installed as far away as possible from the GPS module  2  in an end side of the top casing  100 . The GPS module  2  is installed in an end side of the bottom casing  105  and far away as possible from the embedded antenna module  12 .  
       FIG. 4  shows a perspective, assembled view of the opened display device according to the present invention. The top casing  100  further includes a pair of pivot axles  102 , and a display device  103  pivoted on the top casing  100  by the pivot axles  102  for opening or closing relative to the top casing  100 .  
      The bottom casing  105  further includes a support  107  installed on a bottom side thereof for supporting or positioning the mobile communication device  1  on the dashboard of a vehicle. When the mobile communication device  1  is placed in the vehicle, and the display device  103  is opened, its design is convenient and safe so that a user may use the communication module whilst driving.  
       FIG. 5  shows a perspective, assembled view of when the top casing and the bottom casing are opened according to the present invention. When the top casing  100  and the bottom casing  105  are closed (at this time, the top casing  100  shields the GPS module  2 ), the mobile communication device  1  mates with the embedded antenna module  12  so that it can be used as a “mobile phone”. When the top casing  100  and the bottom casing  105  are opened to expose the GPS module  2 , the mobile communication device  1  mates with the GPS module  2  and the display device  103  so that it can be used as a “GPS”.  
      Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
