For drawing electric energy to power supply electric energy supplement or from power supply, it is supplied to each electronic device.
It is understood that entire intelligent terminal is also by moulding thicker if accommodating space is configured thicker or wider
Or it is wider.Therefore, in this embodiment, the position of mainboard 30 and power supply is laid and uses novel design.Specifically, holding
A framework 40 is equipped in emptying, which accepts the shell 10 and display unit 20 (such as display screen) of intelligent terminal respectively,
Upper part is interconnected with display unit 20, and to fix the position of display unit 20, lower part is fixedly connected with shell 10, by shell
Body 10 is shaped to the outer profile of intelligent terminal.On the stationary plane (end face towards display unit 20) of framework 40, stationary plane is set
The plane for being calculated as plane or flattening substantially, and in power supply arranged side by side on stationary plane and mainboard 30.And power supply be designed as it is split type,
