Description

Portable Computer {

The present invention relates to a portable computer, and more particularly to a portable computer having a main body and a monitor provided to be rotatable about the main body.

In general, as shown in FIG. 1, a conventional portable computer 101 is foldably coupled to an upper portion of a main body 110 that generates an image signal and an upper portion of the main body 110, and receives an image signal from the main body 110. Monitor 120 for receiving and outputting, and the tilting (TILTING) hinge 140 to enable the monitor 120 to tilt the main body 110.

In the main body 110, components such as a CPU and a RAM, including a main board (not shown) are installed, and a keyboard 111 for a typing input operation is provided on an upper surface of the main body 110.

The monitor 120 is mainly thin and forms an image using a light LCD panel.

The tilting hinge 140 is provided in a pair between the main body 110 and the monitor 120 so that the monitor 120 can rotate in the front-rear direction with respect to the main body 110.

Thus, in the conventional portable computer 101, the monitor 120 is rotated in the front and rear direction with respect to the main body 110 by a pair of tilting hinges 140, that is, tilting is easy.

However, the conventional portable computer 101 is provided with a pair of tilting hinge 140, the monitor 120 can be tilted stably with respect to the main body 110, the monitor 120 is relative to the main body 110 Swiveling (SWIVELING) to rotate along the axis in the vertical direction is not possible, there is a problem inconvenient to use.

In addition, a conventional portable computer may be provided with one tilting and swivel combined hinge (not shown) in which the monitor can be tilted and swiveled with respect to the main body.

However, in the case of a portable computer equipped with such a tilting and swivel hinge, the monitor can be swiveled with respect to the main body. However, since the monitor must be tilted with respect to the main body whenever the portable computer is used, a more frequently used tilting part is used. Since it is provided as a combined hinge, there is a problem that the tilting is unstable due to shaking during tilting, and the tilting part is broken by frequent use.

Accordingly, it is an object of the present invention to provide a portable computer capable of tilting more stably and stably, and capable of swiveling.

Accordingly, as shown in FIG. 9, the monitor 20 is capable of swiveling with respect to the main body 10 about the swiveling hinge axis 33 of the biaxial hinge 30.

Accordingly, in the portable computer 1 according to the first embodiment of the present invention, the tilting hinge axis 31 and the tilting hinge 40 of the biaxial hinge 30 when the monitor 20 is tilted with respect to the main body 10. Tilting around the tilting shaft 48 of the) not only enables more robust and stable tilting, but also the tilting hinge 40 is detachably provided when the monitor 20 is swiveled with respect to the main body 10. Swiveling is possible about the swiveling hinge axis 33 of the hinge 30.

10 and 11 are a perspective view and an operation diagram of the portable computer 1 according to the second embodiment of the present invention. As shown in these figures, in the second embodiment of the present invention, the tilting hinge 40 having the same configuration as that of the first embodiment is provided to face the lower left and right sides of the monitor 20, respectively, and the pair of tilting hinges. The difference from the first embodiment is that a biaxial hinge 30 having the same configuration as that of the first embodiment is provided in the central region between the 40.

With this configuration, the operation of the portable computer 1 according to the second embodiment of the present invention will be described as follows. First, in the state where the monitor 20 is folded on the upper side of the main body 10, the monitor is centered around the tilting hinge axis 31 of the biaxial hinge 30 and the tilting axis 48 of the pair of tilting hinges 40. Tilt 20 relative to body 10. Then, when the monitor 20 is swiveled with respect to the main body 10, the pair of levers 55 are tilted to overcome the elastic force of each elastic member 61 provided in the pair of tilting hinges 40. When pulled to the left and right of the direction, the second coupling portion 45 respectively coupled with the pair of first coupling portion 41 is separated from the first coupling portion 41.
