Description

Battery assembly for portable computer and portable computer having same {BATTERY ASSEMBLY FOR PORTABLE COMPUTER AND PORTABLE COMPUTER WITH BATTERY ASSEMBLY}

The present invention relates to a battery assembly for a portable computer and a portable computer having the same, and more particularly, to a battery assembly for a portable computer with improved coupling structure and a portable computer having the same.

In general, a portable computer includes an LCD monitor equipped with an LCD panel and a main body equipped with various hardware supporting the LCD monitor. The portable computer includes a portable computer such as a laptop computer, a laptop computer, and a palmtop computer.

Recently released portable computers are minimized to facilitate portability and mobility, and thus the main body of the portable computer includes only essential functions of the computer. That is, the main body is provided with a main board on which the CPU and RAM are installed, and a hard disk drive in which the operating system is stored. Then, the battery assembly for supplying power when carrying is detachably coupled to the outside of the main body.

In general, the battery assembly includes a battery that provides power for a computer and is rechargeably provided, a coupling means for attaching the battery to the computer, and a power connection means for connecting the power of the battery to the computer.

In addition, the battery is generally classified according to its size and charging capacity, and can be divided into a high capacity battery capable of supplying power for a long time and a low capacity battery having a smaller size and charging capacity than the high capacity battery.

1 is a rear view of a conventional battery assembly separated from a portable computer, and FIG. 2 is a side view of the battery assembly of FIG. 1 coupled to a portable computer.

As shown in these figures, the conventional battery assembly 103 is a battery 140 for supplying power to the portable computer 101, and locking means that is a coupling means for coupling the battery 140 to the portable computer 101 The projection 158 and the like, and a connector 171 which is a power connection means for connecting the power supplied from the battery 140 to the portable computer 101.

The locking protrusion 158 is formed to protrude in pairs on the surface coupled to the portable computer 101 of the battery assembly 130, and is inserted into and coupled to the locking part 113 of the battery accommodating part 111 to be described later.

The connector 171 is provided on the side coupled to the portable computer 101 of the battery assembly 130, and is coupled to the connector receiving portion 116 of the battery receiving portion 111 to be described later.

The portable computer 101 includes an LCD monitor 103 equipped with an LCD panel and a main body 110 supporting the LCD monitor 103 and mounted with various hardware.

The lower portion of the main body 110 is provided with a battery accommodating portion 111 that can accommodate and combine the battery assembly 130.

The battery accommodating part 111 may engage and disengage the locking part 113 provided to accommodate the locking protrusion 158 of the battery assembly 130 and the locking protrusion 158 inserted into the locking part 113. It has a locking knob (114) provided to be able to. In addition, the battery accommodating part 111 is provided with a connector accommodating part 116 coupled with the connector 171 of the battery assembly 130 to transfer the power of the battery 140 to the portable computer 101.

By such a configuration, a process in which the conventional battery assembly 130 is coupled to the main body 110 of the portable computer 101 is as follows. First, the battery assembly 130 is completely inserted into the battery accommodating part 111. Then, the locking protrusion 158 of the battery assembly 130 is coupled to the locking portion 113 of the battery accommodating portion 111, and the connector 171 of the battery assembly 130 is a connector of the battery accommodating portion 111. Is coupled to the receiver 116. Thus, the combination of the battery assembly 130 and the portable computer 101 is completed.

However, such a conventional battery assembly 130 is not fully inserted into the battery accommodating portion 111 formed in the main body 110 as shown in FIG. This is because the space of the battery accommodating part 111 cannot be secured in order to miniaturize the portable computer 101. In particular, when a battery assembly with a large capacity battery is coupled to a portable computer, the battery assembly is excessively protruded from the rear of the main body of the portable computer, and thus the portable computer cannot be placed in the portable computer bag. Therefore, the battery assembly must always be removed. There is this.

Accordingly, an object of the present invention is to provide a battery assembly for a portable computer and a portable computer having the same, which can prevent protruding from the outside of the portable computer.
