Description of drawings
Fig. 1 is the mobile phone circuit structural representation that the utlity model has external charge function.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills make the every other embodiment that is obtained under the creative work prerequisite not doing, and all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of mobile phone with external charge function comprises housing, mainboard, microprocessor controller 100, rechargeable battery 500 and charge inside circuit 200; It is characterized in that: also comprise booster circuit 300 and charging inlet 400, the control end of described booster circuit 300 is connected with described microprocessor controller 100; The input of described booster circuit 300 is connected with the positive and negative polarities of described rechargeable battery 500; The output of described booster circuit 300 is connected with described charging inlet 400.Described booster circuit 300 is used for the output of described rechargeable battery 500 is boosted to the magnitude of voltage that is suitable for external charging.Described charging inlet 400 is used for that described mobile phone and other electronic equipments are carried out circuit and is connected, and realizes externally charging.The output voltage of described booster circuit 300 is 5V.
Described microprocessor controller 100 is provided with control interface 102, and the control end of described booster circuit 300 is connected on the described control interface 102.Thereby realize that described booster circuit 300 begins or power cut-off according to the control signal that described microprocessor controller 100 sends.
Described microprocessor controller 100 also is provided with interrupt interface 101, and described interrupt interface 101 is connected with described charging inlet 400.Like this, when described charging inlet 400 was connected with other electronic equipments, described interrupt interface 101 was received the high level signal that described charging inlet 400 sends, and described microprocessor controller 100 enters interruption, controlled described booster circuit 300 and started working.
Described interrupt interface 101 can be the GPIO interface that is set to.
Described charging inlet 400 is for being provided with the USB interface of earth terminal, power end, first data terminal and second data terminal, and the output of described booster circuit 300 is connected with described earth terminal and power end respectively.Like this, the voltage between described earth terminal and the described power end is 5V, and when described charging inlet 400 was connected with the electronic equipment that is recharged, this 5V voltage was added in the two ends of battery to be charged, is embodied as this battery charge to be charged.
Further, also comprise an analog switch, the two ends of described analog switch are connected with described booster circuit 300 and described charge inside circuit 200 respectively, and the control end of described analog switch is connected with described control interface 102.Like this, when described GPIO interface is received high level signal, described microprocessor controller 100 transmits control signal by described control interface 102, after the control end of described analog switch is received this control signal, controlling described booster circuit 300 conductings and described charge inside circuit 200 opens circuit, described booster circuit 300 is started working and forbid 200 work of described charge inside circuit, prevent that this circuit charges to the battery 500 of the utility model self; It will be appreciated by those skilled in the art that, when the utility model is not connected by described USB interface with other electronic equipments, described microprocessor controller 100 is controlled the state of described analog switch by the control end of described analog switch, described booster circuit 300 opens circuit and described charge inside circuit 200 opens circuit thereby control, can realize like this when no external electronic device is connected with the utility model, not influence the function of the utility model for self charging.
