Summary of the invention
The purpose of this utility model is to provide a kind of mobile phone, is intended to solve the problem that prior mobile phone charges for the mobile phone of needs charging.
The utility model is achieved in that a kind of mobile phone, comprises battery and control unit, its improvement is, described mobile phone comprises that also the operating voltage with described battery is converted to charging voltage, the charging device that the mobile phone that charges for needs charges, and described charging device comprises:
Be connected with the mobile phone of needs charging, for it provides the interface unit of charging voltage; And
Receive the control signal that described control unit sends, the operating voltage of battery is converted to charging voltage and flows to the voltage conversion unit of interface unit.
Another purpose of the present utility model is to provide a kind of charging device, and its improvement is that described charging device comprises:
Be connected with the mobile phone of needs charging, for it provides the interface unit of charging voltage; And
The control signal that reception provides the control unit of the mobile phone of electric energy to send is converted to charging voltage with the operating voltage of described battery of mobile telephone and flows to the voltage conversion unit of interface unit.
In the utility model, mobile phone is provided with charging device, the voltage conversion unit of charging device is converted to charging voltage with the operating voltage of this battery of mobile telephone, and charging voltage is exported to the mobile phone that needs charging by interface unit, be its charging, use the inconvenient problem of mobile phone charging out of doors with regard to having solved like this.
Description of drawings
Fig. 1 is the structure principle chart of the mobile phone charging device that provides of the utility model;
Fig. 2 is the circuit diagram of the mobile phone charging device that provides of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
In the utility model, mobile phone is provided with charging device, and it is converted to charging voltage with the operating voltage of battery of mobile telephone, is the mobile phone charging of needs charging.
Fig. 1 shows the realization principle of the mobile phone charging device that the utility model provides, and for convenience of explanation, only shows the part relevant with the utility model.
Be connected by cable between mobile phone 1 and the mobile phone 2 that needs charging, voltage conversion unit 102 and interface unit 104 have constituted charging device, during the charging beginning, at first move the program in the control unit 103 of mobile phone 1, control control unit 103 sends and enables control signal to voltage conversion unit 102, voltage conversion unit 102 begins the operating voltage of battery 101 is converted to charging voltage, and this charging voltage flowed to interface unit 104, interface unit 104 is exported to the mobile phone 2 that needs charging with this charging voltage by cable, is its charging.
Fig. 2 shows the circuit structure of the mobile phone charging device that the utility model provides, and for convenience of explanation, only shows the part relevant with the utility model.
The central processing unit of mobile phone 1 (CPU) is as control unit 103, and CPU is provided with general purpose input and output (general purpose input/output, GPIO) control end.
Transformation chip U1 is as voltage conversion unit 102, transformation chip U1 is provided with voltage input end Vin, voltage output end Vout and Enable Pin EN, Enable Pin EN is that high level is effective, so its signal that receives is when being high level, and transformation chip U1 begins voltage transitions.
USB interface U2 is as interface unit 104, and USB interface U2 is provided with the VBUS end.
During the charging beginning, at first move the program among the CPU, the GPIO control end of Controlled CPU sends the Enable Pin EN that control signal is given transformation chip U1 that enables of high level, Enable Pin EN is that high level is effective, therefore transformation chip U1 begins voltage transitions, be converted into 5V voltage from the 4V operating voltage of the battery 101 of its voltage input end Vin input, this voltage satisfies the requirement of mobile phone charging voltage, the voltage output end Vout of transformation chip U1 flows to this 5V charging voltage the VBUS end of USB interface U2 by the VBUS line, USB interface U2 exports to the mobile phone 2 that need charging by the OUT end by cable with this 5V charging voltage again, is its charging.Charging finishes, and bolt down procedure pulls out cable and gets final product.
In the utility model, mobile phone is provided with charging device, the voltage conversion unit of charging device is converted to charging voltage with the operating voltage of this battery of mobile telephone, and charging voltage is exported to the mobile phone that needs charging by interface unit, be its charging, use the inconvenient problem of mobile phone charging out of doors with regard to having solved like this.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
