More specifically, the display unit compresses the elastic force of the coil spring in the center and swings, as well as the elastic restoring force of the coil spring. By swinging back automatically to maximize the ease of use according to the operation, and the hinge assembly for swing operation of the display unit of the sliding mobile phone to achieve the assembly workability and slimming of the mobile phone by a simple structure.

In general, wireless terminals (cell phones) are classified into various types, such as bar type, flip type, and folder type. Recently, a slide type mobile phone that is switched to a call mode by pushing the main body with one hand is commercialized. It is becoming.

In addition, the mobile phone has a variety of functions in addition to the recent voice call, for example, through the LCD display of the mobile phone has a multimedia function to watch videos, the Internet, pictures, or use a combination of DMB (DMB).

In the case of such a mobile phone, there is an inconvenience in using the above-described multimedia function as a conventional vertically rectangular LCD screen.

In other words, the vertically rectangular LCD screen has difficulty in sufficiently securing the left and right screens, which is inconvenient to effectively use multimedia functions such as video, Internet, viewing pictures, and DMB.

For this reason, a number of techniques for effectively using multimedia functions by swinging the vertically rectangular liquid crystal screen to horizontally rectangular by rotating the vertically rectangular screen are sufficiently disclosed.

This conventional technology is configured so that the swing plate installed in the mobile phone body and the swing plate installed in the display unit of the LCD screen are connected to the hinge at the center to swing angle in a 90 degree angle range, that is, the display unit is switched from a vertical rectangle to a horizontal rectangle. It is.

In addition, the fixed plate and the swing plate are provided to facilitate the swing rotation and the return rotation of the swing plate by installing a magnet body or a bullet spring between the fixed plate and the swing plate as in Utility Model Nos. 325004 and 402929.

Of course, in the case of the mobile phone of the slide type, the slide plate is coupled to the fixed plate to the slide operation, and the swing plate is hinged to the slide plate to the sliding material to provide the sliding of the slide plate, the swing plate swing swing and return rotation. .

In the case of the mobile phone, the vertical rectangular display unit is detached from the magnetic force pulling the initial magnet body or the display is rotated by an external force compressing the ball spring to rotate the display in a 45 degree angle range. Due to the extension force of the ball spring, the swing is rotated in the remaining 45 degree angle range to switch to the horizontal rectangular display unit.

On the contrary, even when the horizontal rectangular display unit is returned to the vertical rectangular display unit, when the display is rotated in an inverse 45 degree angle range by the external force that separates the magnetic force of the initial magnet body or compresses the ball spring, The swinging force is returned to its original position by swinging the remaining 45 degree angle by the pushing force of the magnet body or the stretching force of the compressed ball spring.

That is, in the conventional swing plate, when the user switches the vertical rectangular display to the horizontal rectangle, or when the horizontal rectangular display is returned to the vertical rectangle, the swing plate directly exerts a constant external force (push or pull with a finger). While the swing operation of the display unit must be performed, there was an inconvenience in operation and use.

In addition, the above-described conventional technology has a disadvantage in that the hinge coupling of the fixed plate and the swing plate does not provide a mutually secure coupling structure or when the hinge coupling is firmly assembled, thus making the structure complicated and not achieving a mutually slim structure.

The present invention was created to solve all the problems of the prior art.

In other words, the present invention compresses the elastic force of the coil spring in the vertical rectangular display unit and swings the horizontal rectangular shape as well as the swing of the horizontal rectangular display unit automatically and automatically swings back by the elastic spring restoring force of the coil spring.

It is communicated when the guide rod 46 of the guide member 45 is further rotated by a coercive constant angle (4 to 8 degrees) in the state of being caught by the locking step 36a of the first guide groove 36 '. By forcibly moving by turning " U " to the escape guide part 38a through the return guide part 38b of the inclination of the second guide groove 36 ", the guide member 45 of the coil spring 40 The restoring elastic force returns to the original position again via the first guide groove 36 '.

That is, since the return guide part 38b is formed in an inclined direction and is formed in a resilient direction of the swing plate 30 by the coil spring 40, the external guide force that presses the swing plate 30 is removed. At the same time, the guide rod 46 of the guide member 45 drops the return guide portion 38b and the release guide portion 38a of the second guide groove 36 ″ from the locking jaw 37 at the center portion of the second guide groove 36 ″. It will automatically return to the original home position through the guide groove (36 ').

In this case, the swing plate 30 guides the guide 45 in the guide path 35 to limit the return rotation range, as well as the hinge part, that is, the assembly protrusion 32 of the swing plate 30 is the slide plate. The stopper 22a formed on the engaging step portion 22 of the 20 is to limit the rotation range.

On the other hand, the present invention is not limited to the above-described sliding cell phone, the same applies to the non-sliding folder-type cell phone, in which case the slide plate is excluded, provided with only a fixed plate and a swing plate mutual hinge portion and The guide body and the guideway, etc. will be provided in the same manner, and the degree of change in the simple structure will be understood to belong to the scope of the present invention.

As discussed above, the present invention compresses the coil spring for the swing rotation operation of the display unit, and the guide rod of the guide member is caught on the locking step formed at the end of the first guide groove of the guide road, and the 90 degree rotation is supported. When the vertical rectangular display unit swings horizontally to maintain the swing, as well as pushes the swing plate at an angle to rotate the display unit in the home position, the guide body is forcibly guided to the second guide groove to burn the coil spring. By releasing the locking state of the force, the automatic return by the coil spring's elastic restoring force, while the horizontal rectangular display part can be easily returned to the vertical rectangle to maximize the convenience of use,

In addition, the hinge coupling structure of the slide plate and the swing plate is inserted into the through hole, but the assembly protrusion is supported by the simple structure that is supported by the engaging step portion has the effect of preventing mutual separation and slimming. .
