The present invention relates to a two-way opening and closing device, in particular, in the electronic device that needs to be opened and closed, such as a portable terminal, the second body from the first body by a combination of the sliding motion and the rotational movement, the second body is convenient to the user This is to keep it at an angle.

Recently, as the penetration rate of portable wireless terminals increases, additional functions that are suitable for the user's taste are required for the portable terminal, as well as simple functions of wireless communication.

In response to these demands, portable terminals have evolved from a general bar type to a flip type, a flip up type, a folder type, and the like. To achieve.

This is because the folder type terminal has enough space to adopt the wide LCD module as a display device, and because it is folded in half and portable, the portability is superior to other terminals.

On the other hand, it is possible to have a display device having a wide LCD module of a similar size as a folder type terminal, and at the same time, a slide type terminal capable of contributing to the miniaturization of the terminal is known.

Such a slide type terminal has an additional advantage that the sub body corresponding to the cover is opened and closed by a sliding operation on the main body, and is opened and closed by a new operation while maintaining the advantages of the existing folder type terminal.

As such a slide type terminal, a sliding type portable wireless terminal is disclosed in Utility Model Registration No. 2003-0000136.

In the terminal disclosed in the present application, as a guide means for guiding the sub body on the main body, guide slits are formed in the longitudinal direction on both sides of the main plate, and guide ribs slidably coupled to the guide slits are formed on the slide plate.

In the terminal, the guide rib is slid along the guide slit, so that the slide plate and the sub body are linearly opened and closed from the main plate and the main body.

On the other hand, in such a sliding terminal, the sub body having the LCD screen moves in parallel from the main body with the keypad. Therefore, the keypad and the LCD screen always maintain 180 ° in parallel.

Typically, when the user uses the terminal for a call, the user attaches the sub body to the ear and brings the main body close to the mouth. The gap between the main body and the sub body, which is most suitable for the user's body, is about 160 °.

Therefore, conventional folder type terminals maintain an opening angle of almost 160 °.

However, the conventional sliding type terminal has an opening angle of 180 ° of the main body and the sub body, so that the user feels inconvenience when using it for a call.

In addition, when the user uses the LCD screen of the terminal to receive text, etc., the user places the terminal in front of him and works by alternating between the keypad of the main body and the LCD screen of the sub body.

In this case, the distance of the terminal branch from the user is about 40cm, and the angle of opening of the main body and the sub body from the user's eyes is about 20 °. Therefore, even in this case, it is most convenient for the terminal to maintain an opening angle of about 160 °.

However, the conventional sliding type terminal has an opening angle of 180 ° of the main body and the sub body, so that the user may feel uncomfortable even when viewing the LCD screen.

As described above, the conventional sliding type terminal has a disadvantage in that the sub body is simply opened from the main body in a slide operation, and thus the opening angle of the main body and the sub body is 180 °, resulting in inconvenience in use.

The present invention has been made to solve the above problems, an object of the present invention is to enable the second body from the first body in the sliding and rotating operation of the second body in the electronic device that needs to be opened and closed, such as a portable terminal In order to maintain the second body at a convenient angle for the user.

Lifting one side edge of the second body 200, the second body 200 rotates about the connecting shaft 320 to rotate in the second direction.

In the initial stage of the rotation operation of the second body 200, the valley of the first waveform surface 332 formed on the first cam 330 of the clutch means, the valley of the second waveform surface 342 formed on the second cam 340 In the process of detaching from the mold part, a resistance force is generated and a resistance force is applied to the rotational motion of the second body 200. However, when the ridge portion of the first cam 330 rises to the plane 344 of the second cam 340, it is free. Since the stop section, the rotation angle of the second body 200 can be freely adjusted.

As shown in the figure, when the second body 200 is continuously rotated in the second direction, when the peak portion of the first waveform surface 332 exceeds the peak portion of the second waveform surface 342, the connecting shaft 320 Rotate in the opening direction of the second body 200 is made automatically.

Accordingly, when the second body 200 is sufficiently rotated in the second direction, the second waveform formed on the second cam 340 by the ridge and the valley of the first waveform surface 332 formed on the first cam 330 again. A predetermined braking force is generated on the connecting shaft 320 by being coupled to the valley portion and the hill portion of the surface 342. Therefore, the second body 200 is maintained in a state rotated in the second direction.

As described above, in the process of rotating the second body 200 in the second direction, the flexible PC 110 electrically connecting the first body 100 and the second body 200 has the same angle as that of the connecting shaft 320. Will be bent.

As such, when the second body 200 is rotated in the second direction, the angle formed by the second body 200 and the first body 100 becomes an angle that is convenient for the user to view and suitable for talking.

The operation of rotating the second body 200 to the initial position in the second direction is performed in the reverse order to the above process.
