Description

Portable computer reinforcement

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcement device of a portable computer, and in particular, a cover is warped by a weight of an LCD panel mounted on the front of the cover when the cover is opened or closed in a portable computer such as a notebook computer. It relates to a reinforcement device of a portable computer to prevent the back portion from lifting.

Recently, a personal computer that is portable because of its compact size, such as a laptop computer or a notebook computer, and can be efficiently used in a limited workspace has been widely used.

Such a portable computer is configured in the form of a suitcase in which the front of the cover is folded with respect to the upper surface of the base in a closed state in order to maximize space efficiency and portability.

1 is an exploded perspective view illustrating a coupling relationship between a base and a cover of a conventional portable computer.

Referring to this, the portable computer 10 has a base 17 on which a data input means such as a keyboard 13 and a touch pad 15 is mounted, and a rear end of the base 17 as a reference point. In the closed and coupled state is made of a cover 19 covering the upper surface of the keyboard (13).

The base 17 is basically equipped with a central processing unit (CPU), a battery for supplying power and a hard disk driver (HDD), etc., which are each configured to be electrically connected to a main printed circuit board (PCB). do.

On the front of the cover 19 is an LCD panel 21 for displaying information input by manipulation of data input means such as a keyboard 13 and a touch pad 15 on a base 17 or a mouse connected externally. It is mounted, there is provided an LCD driving circuit electrically connected to the main PCB and the LCD panel 21.

The base 17 is manufactured in a separated state from each other, and in the combined state, the base panel 23 and the lower panel 25 constitute one body.

The upper surface of the upper panel 23 is formed with a keyboard storage unit 13a on which the keyboard 13 is mounted and a touch pad storage unit 15a on which the touch pad 15 is mounted. It has a predetermined length and height, and a space portion of a predetermined depth is formed therein, and a plurality of bearing portions 29 having a shaft hole 27 communicating with the space portion is protruded at a predetermined interval.

Inside the lower panel 25, a battery mounting portion 25a, a auxiliary memory storage portion 25b, and a PCB mounting portion (not shown) to which the main PCB is mounted are formed.

The cover 19 is coupled to a rear panel (Rear Panel 31) on which the LCD panel 21 is mounted, and is coupled to the front edge of the rear panel 31 to the edge of the rear panel 31 and the LCD panel 21. It consists of a front panel (33) that covers the spaces generated between the edges.

In addition, the rear end of the rear panel 31 and the front panel 33 constituting the cover 19, the cutting groove 35 into which the bearing portion 29 protruding from the upper panel 23 of the base 17 is fitted. Is formed, the shaft hole 27 for fitting the hinge shaft 37 protruding from the bearing portion 29 is formed on the side of the incision groove (35).

In this structure, the bearing portion 29 on the base 17 is fitted into the cut groove 35 on the cover 19, and the hinge hole 37 is formed on the side of the cut groove 35. The cover 19 is pivotally coupled to the base 17 when it is inserted into the base 17.

In the portable computer 10 configured as described above, the rear panel 31 and the front panel 33 constituting the cover 19 are thin and light in weight, whereas the LCD panel mounted on the front of the rear panel 31 ( Since 21) is relatively thick and heavy, there is a problem that the whole cover 19 is severely shaken while the cover 19 is twisted in the process of unfolding the cover 19 from the folded state on the base 17 in order to use a portable computer.

In addition, the base 17 and the cover 19 have a very fragile coupling structure that is only coupled and supported by the hinge shaft 37 fitted to the bearing portion 29.

Therefore, when the opening and closing operation of the cover 19 with respect to the base 17 made in a very large angle range is repeated, the base 17 by the full load of the LCD panel 21 mainly acting toward the hinge coupling portion. The rear part of the upper panel 23 constituting the twisted, there is a problem that the crack occurs in the portion where the hinge shaft 37 is fitted in severe cases.

In addition, the warp phenomenon of the upper panel 23 inevitably causes the separation of the portion coupled with the lower panel 25, which causes a serious problem that damages the circuit pattern on the main PCB mounted inside the lower panel 25. have.

An object of the present invention is to deform the cover and the base according to the repeated opening and closing operation by preventing the cover from being twisted or the back of the base by the weight of the LCD panel mounted on the front of the cover during the opening and closing operation of the cover to the base in a portable computer And to provide a reinforcement device of a portable computer to prevent damage to the circuit pattern on the main PCB mounted in the base.
