Description

Portable terminal with slide-tilt-type opening and closing structure {PORTABLE TERMINAL WITH SLIDE-TILT TYPE OPENING / CLOSING STRUCTURE}

The present invention relates to a portable terminal, and more particularly, to a portable terminal in which a pair of housings are coupled in a slide-tilt manner.

In general, a portable terminal is a device that allows a user to carry a mobile communication function while carrying it, and may be classified into a bar type, a folder type, and a slide type terminal according to its appearance. .

The bar-type terminal is a type in which a data input / output means, a transmitter, and a receiver are mounted in a main body housing, and a keypad, which is a data input means, is exposed at all times, which may cause a malfunction, and the distance between the transmitter and the receiver. There was a limit to miniaturization due to securing problems. However, with the development of sound technology and multimedia services through mobile communication, bar-type terminals equipped with an input / output device using a touch screen are gradually increasing the market share.

The folder-type terminal is composed of a main body, a folder, and a hinge member for rotatably connecting the main body and the folder so that the folder is rotated and opened and closed. In the call mode, the folder is opened to secure a sufficient distance between the transmitter and the receiver, which is advantageous in miniaturization.

The slide-type portable terminal is composed of a pair of housings, and one housing is opened and closed by slidingly moving on the other housing. Such a slide type portable terminal is particularly useful when it is desired to install a separate physical keypad in a terminal provided with a touch screen. That is, simple text information or search can be performed through the touch screen, but when there is much information to be input, the keypad can be opened by simply sliding one housing with respect to the other housing. Therefore, in the case of installing a physical keypad in addition to a touch screen of a smart phone or a tablet personal computer (PC), which is rapidly spreading in recent years, the structure of a slide type portable terminal is utilized.

On the other hand, when the keypad is operated by slidingly moving the housing equipped with the touch screen and the housing equipped with the keypad, the touch screen displays the screen in a direction substantially parallel to the direction in which the keypad is operated, which is inconvenient to use. It is true. Of course, if the keypad is a voice call-oriented terminal consisting of only numeric keys, there will be no inconvenience for the user. On the other hand, if the keypad of the qwerty array, such as the keyboard of the personal computer, the keypad is operated with both hands while the terminal is mounted on a desk or the like. It will be inconvenient.

Therefore, when the tablet PC or the like is configured in a slide type, a tilt structure for positioning the touch screen inclined with respect to the keypad may be provided. When the touch screen is inclined with respect to the keypad, the user may conveniently check the screen implemented through the touch screen while operating the keypad with both hands.

On the other hand, the slide-tilt type portable terminal requires a hinge member for rotatably coupling a pair of housings. In disposing the hinge member on the terminal, it is preferable to prevent the hinge member from interfering while the second housing is slidingly moved with respect to the first housing by being embedded in the first housing. The slide-tilt portable terminal pivotally couples the guide member to the first housing through a hinge member embedded in the first housing, and slidably couples the second housing to the guide member.

The guide member 15 for slidably coupling the second housing (not shown) to the first housing 11 includes guide ribs 16 formed at both ends thereof, and through the hinge member 17, Rotatingly coupled to the first housing (11). A keypad mounting area 13 is provided on one surface of the first housing 11 to open and close according to the sliding movement of the second housing. The guide member 15 is disposed to one side of the keypad mounting area 13 and is always concealed regardless of whether the second housing is slidingly moved.

As mentioned above, it is preferable that the hinge member 17 does not protrude to the outside of the first housing 101, and thus, the hinge member 17 is embedded in the first housing 11 to prevent the hinge member 17 from protruding from the first housing 11. Protrude from the inner side. The hinge member 17 protruding to the inner side surface of the first housing 11 restricts a space in which a circuit device or the like may be disposed in the first housing 11. In addition, the inside of the keypad mounting area 13 is generally assigned to an area 13a for arranging circuit devices including a dome sheet. Therefore, in the case of the battery pack is disposed on one side of the region (13a) for arranging the circuit devices, for the efficiency is preferably a cuboid shape, when the hinge member 17 is located on the battery pack mounting region 19, the battery pack There is no choice but to reduce the size.

Accordingly, the present invention is to provide a slide-tilt portable terminal that can effectively utilize the internal space of the housings.

In addition, the present invention is to provide a portable terminal having a structure that can be easily opened and closed in a slide-tilt while ensuring a battery pack mounting space and the like.
