具体实施方式 Detailed ways
以下结合附图对本实用新型的技术方案作进一步的详细说明。 Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
一种手机过充保护装置，包括壳体1、设置于壳体1两端分别与手机充电器相连的USB接头2和与手机充电数据线相连的USB接口3，壳体1的内部设有控制芯片4，该控制芯片4包括控制单元和开关单元，其中控制单元的输入端通过线路与手机端的手机芯片的输出端相连，控制单元的输出端通过线路与开关单元的输入端相连，所述的开关单元包括二极管与门电路，该二极管与门电路的输出端通过线路与手机端的电池相连，二极管与门电路的输入端通过线路与供电端的手机充电器相连。 A mobile phone overcharge protection device, comprising a housing 1, a USB connector 2 arranged at both ends of the housing 1 to be connected to a mobile phone charger and a USB interface 3 connected to a mobile phone charging data line, and the inside of the housing 1 is provided with a control Chip 4, the control chip 4 includes a control unit and a switch unit, wherein the input end of the control unit is connected to the output end of the mobile phone chip at the mobile phone end through a line, and the output end of the control unit is connected to the input end of the switch unit through a line. The switch unit includes a diode AND gate circuit, the output end of the diode AND gate circuit is connected with the battery at the mobile phone end through a line, and the input end of the diode AND gate circuit is connected with the mobile phone charger at the power supply end through a line.
本实用新型的控制原理为： The control principle of the present utility model is:
1、手机电池过充问题的解决 1. Solve the problem of mobile phone battery overcharging
手机电池在未饱和状态时，控制芯片处于通路状态，电流可通过过充保护装置充电，在充满电后，由手机芯片上的手机管家发出电流已满指令，控制芯片中的控制单元接收指令并把相应的指令传给开关单元，通过开关单元实现由通路状态变为断路状态，此时手机电池将不再充电。 When the mobile phone battery is not saturated, the control chip is in the open state, and the current can be charged through the overcharge protection device. After it is fully charged, the mobile phone housekeeper on the mobile phone chip sends a full current command, and the control unit in the control chip receives the command and The corresponding command is transmitted to the switch unit, and the switch unit realizes the change from the on-circuit state to the off-circuit state, and at this time, the battery of the mobile phone will no longer be charged.
2、手机边充电边使用充电问题的解决 2. Solve the problem of charging while using the mobile phone
手机在边使用边充电时，多数情况充电电流量大于实用消耗电流量，当电池处于饱和状态，由手机芯片上的手机管家发出电流已满指令，控制芯片中的控制单元接收指令并把相应的指令传给开关单元，通过开关单元实现由通路状态转换为断路状态，当使用消耗一定电量后，电池不再处于饱和状态，此时手机芯片中的手机管家再次发出指令，控制芯片的控制单元接收指令并把相应的指令传给开关单元，通过开关单元实现由断路状态转换为通路状态继续充电。 When the mobile phone is charging while using it, the charging current is greater than the practical current consumption in most cases. When the battery is in a saturated state, the mobile phone housekeeper on the mobile phone chip sends a full current command, and the control unit in the control chip receives the command and sends the corresponding The instruction is transmitted to the switch unit, and the switch unit realizes the transition from the on-circuit state to the off-circuit state. After a certain amount of power is consumed, the battery is no longer in a saturated state. At this time, the mobile phone housekeeper in the mobile phone chip sends out another command, and the control unit of the control chip receives Command and transmit the corresponding command to the switch unit, through the switch unit to realize the transition from the disconnected state to the connected state to continue charging.
3、能源浪费问题的解决 3. Solving the problem of energy waste
手机电池处于饱和状态后，过充保护装置通过控制芯片实现自动断电，避免不必要的能源浪费问题。 When the mobile phone battery is in a saturated state, the overcharge protection device realizes automatic power-off through the control chip to avoid unnecessary energy waste.
4、电池损耗问题的解决 4. Solve the problem of battery loss
手机电池处于饱和状态后，继续充电，会使电池处于过饱和状态，这样会使电池寿命缩短，使用过充保护装置可防止对手机电池的损坏。 After the mobile phone battery is in a saturated state, continuing to charge will make the battery in an oversaturated state, which will shorten the battery life. Using an overcharge protection device can prevent damage to the mobile phone battery.
