Description

Mobile terminal {MOBILE COMMUNICATION TERMINAL}

The present invention relates to a mobile communication terminal that can prevent damage to the display screen of the display device.

In general, a mobile communication terminal refers to a portable device such as an HHP, CT-2, a cellular phone, a digital phone, a PCS phone, and the like, and performs a communication function while performing wireless communication with a base station.

At present, such mobile communication terminals are becoming more sensitive and lighter in electronic components, and bar type mobile phones have become commonplace in the first generation, and flip type mobile phones have become common in the second generation. There is a trend that the flip type and the third generation folder type mobile phones coexist.

Among them, the foldable terminal includes a main body, a hinge device for rotatably connecting the folder and the main body and the folder, and is opened and closed by rotating the folder, and in the call standby mode when the folder is in close contact with the main body. The keypad and the malfunction can be prevented, and in the call mode, the folder is unfolded so that the distance between the transmitter and the receiver can be sufficiently secured, which is very advantageous for miniaturization.

In such a mobile communication terminal, a liquid crystal unit (display unit) for displaying information or text is exposed to the external environment as it is, and thus may be easily damaged from an external shock. Therefore, the user may experience time and economic losses for replacing and repairing the liquid crystal unit.

The present invention is to solve such a conventional problem, the object is to provide a new type of mobile communication terminal that can protect the liquid crystal unit from the external shock.

2 is a partial cutaway view of a mobile communication terminal showing a state in which a protective shutter is closed;

3 is a partial cutaway view of a mobile communication terminal showing a state in which a protective shutter is opened.

The mobile communication terminal of the present invention for achieving the above technical problem is the main body is installed keypad assembly; A sub body having a display unit installed at one side thereof and rotatably coupled to the main body by a hinge device; A transparent window mounted to the subbody such that the display unit is protected from an external impact; And a protective shutter installed on the subbody so as to slide back and forth to open and close the front surface of the transparent window.

According to an embodiment of the present invention, the subbody further includes a guide groove into which a protective shutter is inserted, which slides back and forth to open the front surface of the transparent window.

According to an aspect of the present invention, there is provided a mobile communication terminal comprising: a case having an inner space and an open window at one side thereof; A display unit installed in an inner space of the case such that a display screen is exposed to the outside through the window; A guide groove formed in the case adjacent to the window; And a protective shutter installed on the window so that the display screen of the display unit is protected from an external impact and being able to cover or open the window while sliding along the guide groove.

According to an embodiment of the present invention, it further comprises a confirmation window of a transparent material installed between the protective shutter and the display screen of the display unit.

For example, embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited by the embodiments described below. These embodiments are provided to more completely describe the present invention to those skilled in the art. Accordingly, the shape of the elements in the drawings and the like are exaggerated to emphasize a clearer description.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 3. In addition, in the drawings, the same reference numerals are denoted together for components that perform the same function.

1 is a perspective view of a mobile communication terminal according to an embodiment of the present invention, the terminal 100 according to the present invention is a main body 110, a sub, which is opened and closed at a predetermined angle according to a user's selection from the main body. It has a folder 120 which is a body.

Although not shown in the figure, the main body 110 is provided with a keypad assembly composed of a plurality of key buttons, a microphone device which is a transmitter that can transmit voice to the other party during a call.

The folder 120 is rotated about an axis A for opening and closing of FIG. 1 by a hinge device. The folder 120 has a center hinge arm 126 interposed between the first and second side hinge arms 116 and 117 of the main body 110 to rotatably couple the folder 120 to the main body 110. Is installed. An internal hinge device (not shown) is installed in the inner space of the center hinge arm 126.

The folder 120 has a case 122 including an upper casing frame 122a and a lower casing frame 122b. The case 122 has a window 124 open to the front side (ie, the upper casing frame).

1 to 3, the display device 130 is installed inside the case 122 of the folder 120. The display device 130 may be a wide LCD module, preferably a touch screen module. A speakerphone device (not shown for convenience of drawing), which is a receiver, that can receive a voice of the other party during a call, is installed above the display device 130.

The display device 130 is installed such that the display screen 132 is exposed to the outside through the window 124. Basically, the display screen 132 is provided with a transparent transparent window 142 on the front surface, the transparent window 142 is a primary shield for protecting the display screen 132 from external impact. In addition, a protective shutter 144 that opens and closes the window 124 is installed in front of the transparent window 142.

The protection shutter 144 is installed in the window 124 of the upper case frame 122a so that the display screen 132 of the display unit and the transparent window 142 are protected from external impact. The protection shutter 144 covers or opens the window 124 while sliding along the guide groove 146 formed in the case adjacent to the window 124.

For example, in the present embodiment, the protective shutter is composed of two left and right shutters, but this is only one embodiment, and the protective shutter may be made of a single shutter as well as a transparent material.

According to the present invention, the user can protect the display device by closing the protective shutter when not using the mobile communication terminal (FIG. 2), and can be used in a state in which the protective shutter is open when the mobile communication terminal is to be used. (FIG. 3).

In describing the present invention, the mobile communication terminal is illustrated and described, but the mobile communication terminal is a device having a structure in which a display device is installed in a main body or a sub-body, for example, a laptop PC, a camcorder, a PDA, and various models. It can mean.

On the other hand, the present invention can be variously modified and take various forms of the mobile communication terminal having the above configuration. It is to be understood, however, that the present invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood to do.
