Description

Module accumulating type mobile communication device

The present invention relates to a sliding foldable portable mobile communication device, and more particularly, to modularize various functions of a mobile communication device such as a portable mobile communication phone one by one separately and to assemble only a module having a predetermined function as desired by a consumer. The present invention relates to a multi-functional modular portable portable communication device that can be used.

Due to the rapid development of mobile communication technology, high-performance mobile communication devices are being developed one after another, and various kinds thereof are also available. In the form of such mobile communication, direct communication between mobile devices (wireless transceiver), one base station and many mobile devices Communication (MCA radio), communication for selecting a nearby base station from a plurality of base stations (car telephone), and the like, and may also be classified into public mobile communication and dedicated mobile communication. Public mobile communication includes car phones, ship phones, air phones, mobile public phones, and dedicated mobile communication services for public agencies such as police, ambulances, and firefighting.

Such mobile communication devices may be classified into a bar type, a flip type, a folder type, a sliding folder type, and the like according to the type in addition to the above classification. Among them, the bar-type portable telephone is composed of a rectangular pillar-shaped main body, and a liquid crystal display for display is installed on one side of the main body, and a keypad is installed on the lower part of the main body. -piece) and a microphone for transmission, respectively, and have a structure that is equipped with a detachable antenna in the axial direction at one corner of the main body. Therefore, since the handset is always exposed to the outside, it has a simple operation structure of pressing a call button when it wants to start and end a call, but as it is well known, it has a structure in which the LCD screen and the keypad are arranged up and down on the main body. There was a problem that the size of the whole becomes large.

In addition, the flip type portable telephone has a structure in which the flip 105 is opened from the main body 103 and used during a call, as indicated by reference numeral 101 in FIGS. 1A and 1B. The main body 103 and the lower end of the main body 103 are used. And a flip 105 pivotably coupled to it. Here, the main body 103 has a liquid crystal display 107 for display on the top and a keypad 109 for the lower portion of the main body 103, and an earpiece 111 for a sign language and a microphone for a talk (at the upper and lower ends). 113 is provided, and the detachable antenna 115 is attached to one corner part. In particular, the flip phone 101 is provided with a flip sensor 117 on one side of the bottom to detect the opening and closing operation of the flip (105). In addition, the flip 105 is pivotally coupled to the lower end of the main body 103 via a hinge shaft 119 to cover the entire keypad 109. In the case of the telephone 101, the call is opened and the flip 105 is opened during the call, and after the call, the flip 105 may be closed to end the call. At this time, the flip sensor 105 detects that the flip 105 is closed and opened so that the call can be connected or disconnected.

By the way, the flip telephone 101 also has a mechanical function that the flip 105 itself covers the keypad 105 of the main body 103, so that both the LCD screen 107 and the keypad 109 are installed. Difficult to reduce the size (103), and thus had a problem that the overall size must be large, like the bar-type telephone.

In order to solve the problem that the bar-type or flip-type telephone is enlarged in this way, a folding portable mobile telephone as shown by reference numeral 201 in FIG. 2 has been developed.

This folding telephone 201 is composed of a main body 203 and a folder 207 pivotally connected to the upper end of the main body 203 through a hinge shaft 205.

In addition, the microphone 213 for sending is provided in the lower end part of the main body 203, and the earpiece 215 for hydration is provided in the upper end of the folder 207, respectively. Thus, the phone 201 pivotally lifts the folder 207 from the main body 203 as shown in the call, and folds the folder 207 to the front side of the main body 203 and keeps it at the end of the call. Because of the structure, there is an advantage that can reduce the overall size of the storage by half compared to the bar or flip type.

As described above, the folding portable telephone 201 has an advantage of miniaturization, but since the earpiece 215 or the microphone 213 is located inside the folder 207, the folder 207 must be opened in order to make a call. Even if you want to see the screen 209, there was a inconvenience to open the folder 207.

Although not shown as a more advanced form in order to reduce this inconvenience, a dual-fold portable phone having a liquid crystal screen installed on the outer surface of the folder 207 and two liquid crystal screens, or sliding as shown by reference numeral 301 in FIG. A clamshell phone has been developed.

Among these, in the sliding folding type portable telephone 301 as shown in FIG. 3, the folder 305 is rotatably coupled to the left and right about the hinge axis 307 at the top center of the main body 303, and the folder 305. (305) Since the LCD screen 311 installed at the center is always exposed to the outside, regardless of whether the folder 305 is open or not during a call, the contents of the LCD screen 311 can always be checked, as well as the microphone 309. Since the length of the folder 305 is slightly shorter than the length of the main body 303 so that the outside is exposed to the outside, this sliding clamshell portable phone has the advantage of making a call without having to open the folder 305 if necessary. The 301 is basically a liquid crystal display 311, a keypad 315, a battery pack, and the like, in the folder 305 coupled to the main body 303 and the sliding body 303 to be rotated. , Recently developed new functions such as camcorders should be added, and furthermore, functions such as MP3 and VCD are gradually being added, and as a result, the overall size has been enlarged, resulting in poor aesthetics and inconvenience in handling.

The present invention has been proposed to solve the problems of the conventional slide folding type portable phone as described above, by modularizing the various functions added to the sliding folding portable phone into a separate unit, the user can select and use only desired functions arbitrarily. The aim is to ensure that the functionality and handling convenience of the telephone can be harmonized properly.
