DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, an opening and closing device of a portable terminal according to one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is an exploded perspective view illustrating a portable terminal equipped with an opening and closing device according to an embodiment of the present invention, and FIGS. 4 to 6 schematically illustrate a state in which the opening and closing device of the portable terminal according to an embodiment of the present invention is operated. 4 is a state in which the cover is closed, FIG. 5 is a state in which the cover is opened by a predetermined length, FIG. 6 is a state in which the cover is rotated, and FIG. 7 is a cross-sectional view of the "AA" portion shown in FIG. 8 is a cross-sectional view schematically illustrating a state in which a coil spring is operated.

As shown, an opening and closing device of a portable terminal according to one embodiment of the present invention has an antenna 5 for transmitting and receiving a radio signal at one upper side thereof and a keypad 3 for inputting information and operating a function at the front thereof. And a main body 1 having a transmitter 6 incorporating a microphone for transmitting a voice, and a display 4 such as an LCD for displaying text and images on its front face 1a, the upper side of which is formed. In the slide unit 2 is provided with a receiving unit 7 with a built-in speaker for receiving voice is hinged to the main body portion 1 by a coupling member 130 for slidingly engaging the slide portion 2 Connected.

In addition, when the slide unit 2 slides open by a predetermined length, the slide unit 2 is rotated so that the transmitter 6 with the microphone and the receiver 7 with the speaker are close to the mouth and ear of the user, respectively. The inclined member 140 is formed to protrude on a surface where the main body 1 and the slide 2 are in contact with each other.

The inclined member 140 is formed on the front surface of the main body portion 1 in contact with the slide portion 2 and the height of the slide portion 2 to be rotated at a predetermined angle when the slide portion 2 slides in a linear direction over a predetermined length. The inclined plate 141 having the inclined surface 141a and the inclined surface 142a corresponding to the inclined plate 141a so as to slide along the inclined plate 141a on the rear surface of the slide portion 2 in contact with the main body portion 1. It consists of a sliding plate 142 having. And, the angle that the slide unit 2 is rotated by the inclined member 140 is preferably formed between 10 degrees to 30 degrees.

In addition, each of the protrusions 131a protruding in a predetermined width and extending in a lengthwise direction to the rear surface 2b of the slide portion 2 and the guide protrusion 131b having its width extended to the upper end of the protrusion portion. Guide ribs 131 made of a is mounted.

The coupling member 130 has a hinge shaft 132 hinged to the hinge coupling portion formed on the front surface (1a) of the main body portion 1 and the hinge shaft 132 so that the guide rib 131 is accommodated and slid. The guide rail 133 extends by a predetermined length in a direction perpendicular to both ends of the support rib 131.

The guide rail 133 is a plate-shaped guide plate 133a extending to a predetermined length in a direction perpendicular to the longitudinal direction of the hinge shaft 132 at a portion away from both ends of the hinge shaft 132, and a guide plate. Both sides of the 133a are bent in a vertical direction and extend in the longitudinal direction along the guide plate 133a, and the guide ribs 131 are accommodated so that the guide ribs 131 can be slid without being separated. The ends of the bent portion 133b are formed of the support portion 133c that is bent inwardly facing each other.

In addition, the coil spring 134 disposed between the guide rail 133 and the main body 1 and having both ends connected thereto is released from the state in which the slide unit 2 is rotated by the inclined member 140. The elastic restoring force is then provided to return to the original parallel state.

In the opening and closing device of the portable terminal configured as described above, as shown in FIG. 4, the user wants to make a call while the slide unit 2 is closed to the main body unit 1 or to open the slide unit 2 for other reasons. In this case, when the user pushes the slide unit 2 in the longitudinal direction, as shown in FIG. 5, a guide rail fixed to the main body unit 1 is fixed until a predetermined section, that is, about 80% of the sliding section is slid. The guide rib 131 fixed to the slide unit 2 along the 133 slides so that the slide unit 2 opens.

When the user applies additional force in the state, as shown in FIG. 6, the slide unit 2 slides along the guide rail 133 while the guide rib 131 formed on the slide unit 2 slides along the guide rail 133. The inclined surface 142a of the sliding plate 142 formed on the rear surface 2b of 2) is formed on the inclined plate 141 while contacting the inclined surface 141a of the inclined plate 141 formed on the front surface 1a of the main body 1. As the inclined surface 142a of the sliding plate 142 is slid along the inclined surface 141a, the hinge shaft 132 hinged to the main body 1 is rotated so that the slide unit 2 is rotated so that the user can talk. The transmitter 6 formed in the main body 1 and the receiver 6 formed in the slide 2 can be located close to the user's mouth and ears.

In addition, as shown in FIG. 6, when the user applies a force in the opposite direction while the slide unit 2 is rotated, the sliding plate 142 is inclined surface of the inclined plate 141 by the elastic restoring force of the coil spring 134. As shown in FIG. 5 while descending along 141a, the guide rib 131 is slid along the guide rail 133 while the main body 1 and the slide unit 2 remain parallel to each other. Will be.

As described above, the opening and closing device of the portable terminal according to the present invention has the hinge shaft 132 of the rear portion 2b of the slide portion 2 along the guide rail 133 of the coupling member 130 hinged to the main body portion 1. When the guide rib 131 fixed to the sliding plate is opened for a predetermined length or more, the sliding plate 142 is slid along the inclined surface 141a of the inclined plate 141 while the coupling member 130 is rotated to guide the guide rail of the coupling member 130. In response to the guide rib 131 supported by 133, the slide unit 2 is rotated at a predetermined angle with respect to the main body unit 1, so that the user and the transmission unit 6 formed in the main body unit 1 during a call The receiving unit 6 formed on the slide unit 2 is to be located close to the user's mouth and ears.

As described above, the opening and closing device of the portable terminal according to the present invention slides the guide rib fixed to the rear of the slide part along the guide rail of the coupling member hinged to the main body, and slides the inclined surface of the inclined plate when the length is opened for a predetermined length or more. As the sliding plate is slid, the engaging member is rotated, and the slide unit pivots at a predetermined angle with respect to the guide rib supported by the guide rail of the engaging member so that the user is formed on the transmitting unit slide unit formed in the main body unit during a call. The receiver can be located close to the user's mouth and ears, making it easier to use and increasing the sensitivity of speech and sign language.
