The present invention relates to a portable computer, and more particularly, to a portable computer having an improved casing structure.

In general, portable computers are more portable than desktop computers, and their use is increasing. Portable computers include notebook computers, personal digital assistants (PDAs), tablet computers, and the like.

The portable computer includes a main body including a main circuit unit and a storage unit, a keyboard unit for inputting data into the main body, and a monitor provided rotatably in the main body and outputting the input data.

In general, portable computers are easy to carry, so users often carry them by hand, and they are often used outdoors as well as indoors. Therefore, the casing of the main body including the main circuit unit and the storage unit protects internal components from external forces. Proper durability is required.

Accordingly, the conventional portable computer is produced by including a plastic or magnesium material having a certain thickness so that the casing constituting the main body at the time of manufacture has a suitable strength.

Recently, portable computers have been miniaturized for easy portability according to a user's use, or the size of the portable computer has become relatively large to replace a desktop computer. Among them, the portable computer prepared to replace the desktop computer has a performance that is higher than that of the conventional desktop computer, so that the size of the storage unit accommodated in the main body and the number of components increase, and the size of the main body increases, thereby increasing the weight of the main body.

Thus, there is a need to simply increase the strength of the casing of such large sized portable computers.

It is therefore an object of the present invention to provide a portable computer comprising a casing having a large strength without making a great change in thickness and weight.

The object is, according to the present invention, a portable computer comprising a main circuit portion and a casing in which a storage portion is received, the reinforcement having an embossed portion interposed between the casing and the main circuit portion and protruding to correspond to the shape of the main circuit portion. It is achieved by a portable computer comprising a member.

Here, the reinforcing member is preferably provided with a material different from the casing portion.

In addition, the reinforcing member is preferably a different material containing SUS.

On the other hand, the reinforcing member is formed with a coupling hole for coupling with the casing, the casing is formed with a coupling protrusion coupled to the coupling hole, it is preferable that the coupling hole and the coupling protrusion is coupled by fusion.

Here, the storage unit may be a 3.5 "hard disk.

In addition, the embossing unit is preferably provided in plurality.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The main body 100 includes an upper casing 110 and a lower casing 150 coupled to each other, and a central processing unit (CPU) 121 and a central processing unit (CPU) are disposed between the upper casing 110 and the lower casing 150. And a main board 120 equipped with a cooling fan 123 for cooling 121, and a storage unit (not shown) in which data is stored.

The keyboard unit 200 is mounted on the upper side of the upper casing 110, and the touch pad 130 is provided on the lower side to perform a mouse (not shown) function by touching a hand or the like. The keyboard unit 200 includes a plurality of keys 210 and a keyboard panel 220 provided below the key 210 to mount the keys 210.

The lower casing 150 includes a casing member 160 accommodating the main board 120 and a reinforcing member 170 interposed between the casing member 160 and the main board 120 to increase the strength of the casing member 160. ).

The casing member 160 has an accommodation space A in which the main board 120 is accommodated, as shown in FIG. 3, and includes a storage coupling space B in which a storage unit (not shown) is mounted. The accommodation space A is provided with a plurality of air inlet / out portions 161 through which air is introduced to cool the heat generated when the various components mounted on the main board 120 are driven. In general, the air inlet / out unit 161 is more preferably provided to correspond to the position of the cooling fan 123 mounted on the main board 120, thereby increasing the cooling efficiency.

In addition, the receiving space (A) is provided with a coupling rib 163 coupled to the reinforcing member 170. Coupling rib 163 is preferably provided along the shape of the outer periphery of the reinforcing member 170 and the length so as not to cause interference with the main board 120 mounted in the receiving space (A).

The storage unit coupling space B is equipped with a storage unit (not shown). The storage unit (not shown) may be provided with a hard disk in which data is stored, a CD-ROM in which a compact disk (CD) is stored, and a floppy disk in which a floppy disk is stored. In addition, a USB connector may be provided which can be equipped with a universal serial bus (USB) memory, which has recently been easy to carry and its use is increasing.

The hard disk of the portable computer according to the present invention may have various sizes, and in particular, may be a 3.5 "hard disk corresponding to the hard disk capacity of a desktop computer or a hard disk having a size larger than that.

Here, the casing member 160 is preferably provided with a light weight material to reduce the weight of the main body 100, it may be provided including a plastic, magnesium and the like having a predetermined thickness.

Reinforcement member 170 is provided in a plate shape as shown in Figure 4 is provided between the main board 120 and the casing member 160 to enhance the strength of the casing member 160. The reinforcing member 170 is provided to a thickness that does not cause interference when the main board 120 is accommodated in the accommodation space (A) of the casing member 160, and interferes with the components mounted on the main board 120 It has an embossed portion 173 protruding so as not to cause a.

As shown in FIG. 2B, the embossing part 173 is protruded from the plate surface of the reinforcing member 170 and accommodated in the recessed portion of the main board 120 to support the main board 120 and increase strength. . As shown in FIG. 4, the embossed portion 173 may be continuously protruded to a predetermined thickness or may be protruded discontinuously. In addition, a plurality of embossing units 173 may be provided at positions where interference with the main board 120 occurs.

The reinforcing member 170 is a through portion 171 provided to correspond to the air inlet and outlet 161 and the coupling ribs provided in the casing member 160 so as not to disturb the flow of air entering and exiting through the air inlet and outlet 161. 163 includes a coupling hole 175 to engage with. The coupling hole 175 is provided to correspond to the thickness and position of the coupling rib 163, and after receiving the coupling rib 163, the coupling hole 175 is integrally coupled with the coupling rib 163 by a method such as heat welding or ultrasonic welding. As a result, the reinforcing member 170 is integrally coupled with the casing member 160, thereby increasing the strength of the casing member 160.

The reinforcing member 170 is preferably made of a material different from that of the casing member 160, and more preferably made of a material having a stronger strength than that of the casing member 160. Among them, stainless steel (SUS) series is preferably used as the reinforcing member 170 because of its high strength and high durability and wear resistance.

On the other hand, the above-described embodiment of the present invention has been described as the reinforcing member 170 is coupled to the lower casing 160 to enhance the strength, the reinforcing member 170 is coupled to the lower surface of the upper casing 110, the upper casing The strength of 110 can also be increased.

Referring to the assembly process of the lower casing 150 of the portable computer 1 according to the present invention having such a configuration as follows.

First, the coupling rib 163 of the casing member 160 is inserted into the coupling hole 175 of the reinforcing member 170 to couple the reinforcing member 170 to the casing member 160. The coupling hole 175 and the coupling rib 163 are integrally provided by fusion.

Subsequently, the main board 120 is mounted on the upper surface of the reinforcing member 170, the storage unit (not shown) including the keyboard unit 200 and the hard disk is mounted, and then the upper casing 110 is mounted on the lower casing 150. To complete the assembly.
