TECHNICAL FIELD
The disclosure relates to a communication equipment technical filed, and in particular to an intelligent terminal.
BACKGROUND
At present the processer's speed of intelligent terminals are faster and faster, and the requirement of screen is bigger and bigger, which also has a trend to be thinner. Because of the big screen and other reasons, the power consumption is greatly increasing. So the high-capacity battery is needed. As shown in FIG. 1, a traditional battery 200 of an intelligent terminal is in a regular shape, such as square, and occupied a core location of the terminal. Because the layout of the battery 200 is considered firstly, the rest space is used for arranging a main board (100 and 101). In general, the main board is a broken board, an L-shaped board or a C-shaped board which matches the battery and is mounted in a shell of the terminal. The main board, as shown in the FIG. 1, uses a broken board structure and comprises the first sub-board 100 and the second sub-board 102. Electronic components are arranged on the first sub-board 100 and the second sub-board 101.
The structure design of the intelligent terminal has the following defects:
1. when using the broken board structure, the shape of the broken board is not continuous and at least one sub-board is needed to assist the main board. A Flexible Printed Circuit (FPC) is used to join the sub-boards together. The reliability of signal transmission between single boards is bad and the utilization of the board space is low. When the main board is L-shaped or C-shaped, it also leads to the low utilization of board space because the L-shaped or C-shaped main board is irregular in shape.
2. the battery occupies the most space of the terminal space, and the main board is irregular in shape or divided into a plurality of sub-boards. Due to the structure, it is not easy to radiate the heat and the electromagnetic compatibility may not be improved.

Preferably, the front projection of the battery is L-shaped and the front projection of main board is rectangular in shape or L-shaped.
Preferably, the front projection of the battery is U-shaped and the front projection of the main board is rectangular in shape or T-shaped.
Preferably, the battery is mounted immovably in the shell of the intelligent terminal.
Preferably, the intelligent terminal further comprises a power processing component, a signal processing component, an interface component and a memory, and the power processing component, the signal processing component, the interface component and the storage are arranged on the main board.
Preferably, the signal processing component comprises a baseband chip, a radio frequency chip and a power amplifier, and the baseband chip is arranged on one side of the main board, and the memory, which is opposite to the baseband chip, is arranged on the other side of the main board, and the radio frequency chip is arranged on one side of the main board, and the power amplifier, which is opposite to the radio frequency chip, is arranged on the other side of the main board; and the power processing component comprises battery connector and power management element, and the interface component comprises a USB interface, and the battery connector is connected to the battery and the main board, and the power management element and the USB interface are arranged near to the battery connector.
Preferably, the power management element, the baseband chip, the memory, the radio frequency chip and the power amplifier are evenly arranged on the main board.
In the intelligent terminal provided by the embodiment of the present disclosure, the shape, size and the location in the terminal of the main board are determined firstly. After arranging the main board, the shape of the battery is determined to be an irregular polygon based on the rest space. The battery can take advantage of the rest space of the terminal.

The main board 10, as an important part of terminal, is not only a support body of electronic components, but also a provider for connecting electronic components. The intelligent terminal provided by the embodiment of the present disclosure may be a mobile phone or a tablet computer and so on.
The battery 20 at least half surrounds the main board 10. That is the battery 20 at least partially surrounds two adjacent sides of the main board 10.
The front projection of the battery 20 in the embodiment is an irregular polygon, and the shape of the front projection of the main board 10 matches the shape of the front projection of the battery 20.
The shape of the front projection of the main board 10 may be a regular polygon or irregular polygon and the front projection of the battery 20 may be L-shaped, U-shaped, T-shaped or other irregular polygonal. As shown in FIG. 3, when the front projection of the battery 20 is L-shaped, the front projection of the main board 10 is rectangular in shape or L-shaped which matches the front projection of the battery 20, and the battery 20 half surrounds the main board 10. As shown in FIG. 4, when the front projection of the battery 20 is U-shaped, the shape of the front projection of the main board 10 is rectangular in shape or T-shaped which matches the shape of the front projection of the battery 20, and the battery 20 half surrounds the main board 10. The shapes of the front projection of the battery 20 and the main board 10 are just examples which are used to explain the disclosure rather than to limit the disclosure.
