具体实施方式
下面结合图1-3和实施例对本发明作进一步详述，以下实施例只是描述性的，不是限定性的，不能以此限定本发明的保护范围。
如图1和图2所示，图1为本发明移动电源的结构示意图，图2为本发明移动电源的电路模块结构示意图。
一种移动电源，包括外壳1和灯头2，灯头2上设置LED灯，灯头2的一端通过转轴与外壳1活动连接，移动电源还包括控制电路，控制电路包括MCU、输入接口、CC-CV充电芯片、DC-DC升压电路和输出接口，还包括数码管显示单元和锂电池保护电路，输入接口、输出接口、CC-CV充电芯片、数码管显示单元和DC-DC升压电路均和MCU通信连接，锂电池保护电路与DC-DC升压电路并连，输入接口、CC-CV充电芯片、DC-DC升压电路和输出接口依次连接；还包括与DC-DC升压电路连接，通过感应灯头2相对于外壳1的转动位置，控制LED灯点亮或熄灭的照明单元。
输入接口为MICRO USB接口。
DC-DC升压电路采用异步升压驱动外界MOS管的方式进行升压。
还包括12位模数转换模块，12位模数转换模块集成在MCU上。
数码管显示单元为3位共阴极8位式数码管。
外壳1与灯头2相对应处设置一磁体3。
在外壳1内部设置有三个加速度传感器，三个加速度传感器分别朝向不同的方向设置，三个加速度传感器分别与MCU通信连接。
一种通过摇一摇显示移动电源剩余电量的方法，移动电源为上述的移动电源，晃动该移动电源，外壳内部的三个加速度传感器针对三个方向的加速度进行计算，间隔测量它们在固定时间段里的变化率，并设定一个阈值作为触发摇一摇动作；当摇一摇动作超过所设定阈值时，MCU触发数码管显示单元工作，从而显示移动电源的剩余电量。
本移动电源剩余电量精确显示的工作原理：
1.外部通过MICROUSB接口给移动电源提供5V的充电工作电压，当接入充电时会产生一个上升沿，这个上升沿可以让单片机(MCU)从睡眠模式产生中断唤醒进入正常工作模式，同时5V工作电压通过一个线性CC-CV充电芯片，转换成4.2V给锂离子电池恒流恒压充电。
在正常充电过中，线性CC-CV充电芯片的第6脚输出为高电平，当电芯充满时，第6脚输出转变为低电平。单片机检测到这个电平变化后，在数码管上输出显示“100”，提示用户移动电源己经充满。
2.DC-DC升压电路采用异步升压驱动外接MOS方式，把电芯电压(2.75～4.2V)升压到5V2.1A输出。
3.MCU控制单元内部集成12位AD高精度模数转换模块，在工作状态实时采集电芯的电压，电流，根据时间对应关系计算得到电池的实际容量。通过数码管显示出来。
4.数码管选用3位共阴极8位式数码管，根据人眼的20ms视觉性特征，采用扫描的方式来驱动。
5.锂电保护电路是移动电源上很关键的一个电路，由专用的锂电保护芯片加两棵低压N沟道MOS组成，具有过充，过放，过流，短路保护的功能。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书的保护范围为准。
