[0001] The present invention relates to a notebook computer battery pack having a novel structure,

The present invention relates to a notebook computer battery pack having a novel structure, and more particularly, to a battery pack mounted on one side of a notebook computer main body, comprising: a first pack body having at least one battery cell mounted thereon; A second pack body having at least one battery cell mounted thereon; A connector for variably connecting one end of the first pack body and one end of the second pack body so that the first pack body and the second pack body can be stacked one on another; An external input / output terminal of a battery pack electrically connected to a battery cell of the first pack body and a battery cell of the second pack body and located on the connector; To a battery pack.

The development of technology for mobile devices has provided notebook computers capable of performing comparable to desktop computers, and in recent years, demand for notebook computers is very high.

One of the biggest advantages of notebook computers is that they are easier to carry than conventional desktop computers, and one of the biggest roles in making them portable is battery packs, which are energy sources for notebook computers.

2. Description of the Related Art Generally, a battery pack of a notebook computer is composed of a plurality of unit battery cells and a battery pack case incorporating the same. Particularly, a secondary battery used for a device such as a notebook computer is mainly used for a high output large capacity cylindrical battery cell.

In a battery pack using a cylindrical battery cell, the battery pack is formed in a shape corresponding to the cylindrical battery cell when mounted in the main body of the notebook computer.

1 is a perspective view of a notebook computer equipped with a notebook battery pack according to the related art.

1, the battery pack 10 is a power source mounted on the rear surface and the bottom surface 22 of the notebook computer main body 20 and is built in the inside thereof and connected by a connector 12, (Not shown).

Such a cylindrical battery generally has a larger electric capacity than a prismatic and pouch-shaped battery, but as shown in Fig. 1, due to the stylized design in which the battery pack is mounted on the back and bottom of the notebook computer body, There is a problem that only the provided battery pack is used, and the overall structure of the notebook computer is manually restricted.

Accordingly, development of a battery pack technology for a notebook computer with a flexible structure, which is easy to change and compact in structure, is desperately required.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-described problems of the prior art and the technical problems required from the past.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a battery pack for a notebook computer, which can be easily changed to an expandable structure as required, has a compact structure, and can increase the flexibility of mounting according to specifications of the notebook computer main body.

According to an aspect of the present invention, there is provided a battery pack mounted on one side of a main body of a notebook computer,

A first pack body on which at least one battery cell is mounted;

A second pack body having at least one battery cell mounted thereon;

A connector for variably connecting one end of the first pack body and one end of the second pack body so that the first pack body and the second pack body can be stacked one on another; And

An external input / output terminal of a battery pack electrically connected to a battery cell of the first pack body and a battery cell of the second pack body and located on the connector;

As shown in FIG.

Conventional notebook computer battery packs have a structure that is structured to have a limitation in implementing a flexible structure.

Compared with such prior art battery packs, the battery pack according to the present invention is variably connected to the first pack body and the second pack body by a connector, so that the first pack body and the second pack body are stacked The first pack main body and the second pack main body can be expanded and extended.

Further, since the external input / output terminal is located on the connector having the variable connection structure, the flexibility of the mounting is high according to the specification of the notebook computer main body to which the battery pack is mounted. For example, when the first pack body and the second pack body are laminated to each other, the external input / output terminal is located at one end of the battery pack, and when the first pack body and the second pack body are opened, And is located on the center line of the battery pack. In some cases, the first pack body and the second pack body may be expanded so as to be bent at a predetermined angle in a range of more than 0 degrees and less than 180 degrees. In this case, the external input / ≪ / RTI > As a result, the design of the notebook computer main body can be diversified in consideration of such mounting flexibility.

The battery cell may preferably be a secondary battery, more preferably a lithium secondary battery, regardless of its form. Particularly, when a plate-shaped battery cell is used, the thickness can be minimized. Such a secondary battery includes a battery cell in which an electrode assembly of a positive electrode / separator / negative electrode is sealed together with an electrolyte in a case, and a protection circuit module (PCM) mounted on or attached to such a battery cell.

In one preferred embodiment, the first pack body and the second pack body may each have a rectangular structure, and the first pack body and the second pack body may preferably have a mutual size May be the same structure.

The connector is not particularly limited as long as it provides a variable connection structure, and may be, for example, of a hinge structure. Therefore, the first pack body and the second pack body can easily be stacked and expanded as the hinge structure of the connector spreads to the left and right.

The battery cells of the first pack main body and the second pack main body are not particularly limited as long as they can be electrically connected to the external input / output terminals easily, and may be connected in series or in parallel if necessary.

Meanwhile, although the battery pack according to the present invention is defined as being mounted on the main body of a notebook computer, those skilled in the art will readily recognize that the battery pack may be mounted on other mobile device bodies as the case may be. Therefore, it goes without saying that the scope of the present invention can be extended to a mobile device body other than the notebook computer main body.

The present invention also provides a notebook computer including the battery pack as a power source. A notebook computer using a battery pack having a plurality of secondary batteries therein is well known in the art, so a detailed description thereof will be omitted herein.

The notebook computer according to the present invention has a structure in which the first pack body and the second pack body are mounted on one side of the battery pack in a state in which the first pack body and the second pack body are laminated, completely folded or bent at a predetermined angle. The installation position of the battery pack can be any direction such as the front surface, the right side, the left side, and the rear side of the computer main body.

Therefore, in one example, the battery pack is a structure in which the first body and the second body are mounted on the body of the notebook computer by mutually stacking.

In another example, the battery pack is a structure in which the first body and the second body are mounted on the body of the notebook computer with a structure spreading 180 degrees.

In another example, the battery pack has a structure in which the first body and the second body are mounted on the notebook computer body with a structure bent at an angle of more than 0 degrees and less than 180 degrees.

As described above, since the battery pack according to the present invention can be mounted on the main body of the notebook computer in various manners, the battery pack can be flexibly designed, and thus it is possible to design a notebook computer based on various designs.
