## Background
BACKGROUND OF THE INVENTION
1. Field of Invention
The invention relates to a portable computer and battery device thereof and, in particular, to a portable computer with an exposed battery device and the battery device.
2. Related Art
The portable computer is a kind of portable personal information devices. In addition to a fixed power cord, it also has a built-in battery set. Therefore, the user can move and operate it anywhere, even outdoors, by using the battery power without being restricted by the fixed power cord.
However, as users need the batteries capable of operating the lasting time, manufacturers usually increase the number of cells inside the battery set. Nevertheless, this also increases the volume and weight of the battery. This method is against the idea of providing compact electronic devices nowadays. This may also affect the design of other components in the computer.
As shown in FIG. 1, a conventional portable computer 1 usually has a battery device 12 installed inside the host 11. At the bottom of the portable computer host 11, a battery containing portion 13 is provided for the battery device 12 to provide the power. The designers usually do not design the shapes of the battery device 12 and the portable computer 1. Instead, they simply design a containing portion at the bottom of the host 11. If the number of battery devices 12 increases, most space is needed to accommodate the battery devices 12. Thus, the size of the portable computer 1 has to be enlarged.
It is therefore an important subject to increase the battery lasting time by increasing the number of cells without increasing the volume of the portable computer.

The first shell 21 has a first concave portion 211, a first fixing portion 212, and a connecting portion 213. The first fixing portion 212 is installed adjacent to the first concave portion 211. The connecting portion 213 is connected to the electronic device.
As shown in FIGS. 3A and 3B, the second shell 22 has a second concave portion 221 and a second fixing portion 222. The second concave portion 221 is installed opposite to the first fixing portion 212 so as to form a first containing portion 23. The second fixing portion 222 is installed opposite to the first concave portion 211 so as to form a second containing portion 24. In this embodiment, the first shell 21 and the second shell 22 can be connected by the method of gluing, locking, or clicking. The first containing portion 23 and the second containing portion 24 are installed abreast to each other and form a setting plane P1 (as shown in FIG. 3B), which has an angle of θ1 (as shown in FIG. 3B) relative to the assembling plane P2 composed of the battery device 2 and the electronic device. In general, the angle θ1 can be roughly between 10 degrees and 90 degrees. In more precise, the angle θ1 is between 30 degrees and 60 degrees. In this embodiment, the angle θ1 is 45 degrees.
With reference to FIG. 4, the battery device 2 in this embodiment further includes a first battery set 31, a second battery set 32, and several electrical terminals 41. The first battery set 31 is installed inside the first containing portion 23, and the second battery set 32 is installed in the second containing portion 24. The electrical terminals 41 are installed on the battery device 2, on either the first shell 21 or the second shell 22 for electrically connecting to the electronic device. They are used to transmit electrical power or signals. For example, the electrical terminals 41 can be used to supply power to the electronic device or to charge the battery sets, or even to transmitting the signal of detecting the capacity of the battery sets. Thus, after a proper design, the electrical terminals 41 can be used to transmit either power or signals.
To make the portable computer and the battery device thereof of the invention more comprehensive, an example showing that the battery device 2 is applied to a portable computer will be described hereinafter.
As shown in FIG. 5, the portable computer 5 of the invention includes a host machine 51 and a display 52.
