FIGS. 1 to 3 illustrate only major portions to understand the concepts of the present invention specifically, and thus various modifications of the drawings may be expected and the scope of the present invention is not limited to specific shapes shown in the drawings.
Referring to FIG. 1, a tablet computer 100 of the present invention includes a mobile phone mounting portion 110, a port 120, an interface 130, and a separation prevention member 300.
The mobile phone mounting portion 110 is an area in which a mobile phone 200 is mounted on the rear 111 of the tablet computer 100. Here, the rear of the tablet computer means a surface opposing a front surface in which a display window is formed. The mobile phone mounting portion 110 may be formed in the rear 111 of the tablet computer 100 in a recessed manner so that a space on which the mobile phone 200 is mounted is formed.
In addition, an entrance 112 of the mobile phone mounting portion 110 may be formed in a lateral direction of the tablet computer 100. Such a mobile phone mounting portion 110 may be formed to allow the mobile phone 200 to be slidingly inserted into the mounting portion from a lateral direction of the tablet computer 100.
The port 120 is formed in an inner end of the mobile phone mounting portion 110, and electrically connects the tablet computer 100 with the mobile phone 200 so that the computer and the phone may communicate with each other. The port 120 may connect to the interface 130 formed inside the tablet computer 100. In addition, although the port 120 may be formed in an inner end of the mobile phone mounting portion 110, the present invention is not limited thereto, and proper modifications may be performed under consideration of the position of a data port of a typical mobile phone 200 and the direction where the mobile phone 200 is inserted into the mobile phone mounting portion 110.
The tablet computer may be configured to supply electrical energy charged in any one battery among the mobile phone mounted on the mobile phone mounting portion 110 or the tablet computer 100 to the other battery through the port 120. Accordingly, electrical energy may be easily exchanged between the mobile phone 200 and the tablet computer 100, even in a case in which electrical energy fails to be supplied to the tablet computer or the mobile phone outside.
In addition, the mobile phone 200 mounted on the mobile phone mounting portion 110 is configured to receive electrical energy from the tablet computer 100 through the port 120, and thus a battery capacity of the mobile phone 200 may be led to be significantly reduced.
The interface 130 is formed inside the tablet computer 100 and connects to the port 120. The interface 130 may use any one, which has a communication module connecting an external network, e.g., 3rd Generation (3G), 4th Generation (4G), etc., provided by common carriers, of the tablet computer 100 or the mobile phone 200 to perform a tethering connection to the other one which does not have a communication module. For example, the interface 130 supports the table computer 100 to allow voice and video calls or text message communication to be performed in the tablet computer using the communication module in the mobile phone 200, in a case in which a communication module connecting to an external network is provided to the mobile phone 200 rather than the tablet computer 100. However, the interface 130 supports the mobile phone 200 to allow voice and video calls or text message communication to be performed in the mobile phone using the communication module in the tablet computer 100, in a case in which a communication module connecting to an external network is provided to the tablet computer 100 rather than the mobile phone 200.
In addition, in a case in which the mobile phone is a terminal that may run application programs, such as a smart phone, when the mobile phone is mounted on a tablet computer, the tablet computer may be configured to run the application programs stored in the mobile phone.
Furthermore, according to the embodiment of the present invention, when a mobile phone is mounted on a tablet computer, the tablet computer may be configured to have a mobile phone only mounted thereon, instead of providing a communication or power connection function between the tablet computer and the mobile phone.
Besides, according to the embodiment of the present invention, when a mobile phone is mounted on a tablet computer, the tablet computer may be configured to allow the mobile phone to use power therefrom, instead of providing communication connection function between the tablet computer and the mobile phone.
