Description

Device for realizing mobile phone as power supply
Technical Field
The invention relates to the field of mobile equipment charging, in particular to reverse charging of a mobile terminal in an electronic technology.
Background
With the improvement of living standard and the current progress of communication mode, mobile phones become indispensable and portable articles for people. The mobile phone stores electricity, but cannot supply power to other electronic equipment. If the mobile phone has sufficient electric quantity and other electronic equipment (such as another mobile phone) needs power supply, the mobile phone can be reversely charged and can be charged as a charging device, so that great convenience is provided for users.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a device that uses a mobile phone as a "charger analog" to realize a mobile phone as a power supply in order to solve the emergency power consumption situation of a small electronic device.
The technical scheme of the invention for realizing the device of the mobile phone as the power supply is as follows:
directly adhering a power supply circuit board to a mobile phone backboard, installing an electric quantity output port as a new USB interface on the side surface of the mobile phone, and covering the electric quantity output port by using an adhering piston; the power supply circuit board comprises a battery cell respectively connected with a booster circuit and a charging circuit, the booster circuit is connected with an input end, the charging circuit is connected with an output end, the input end is connected with an input port of the mobile phone, and the output end is connected with electronic equipment needing charging.
The invention has the following beneficial effects:
1. when the electric quantity of the other electronic equipment is exhausted, the mobile phone can be used as the electric quantity output end to charge the other mobile phone or other electronic equipment, so that some emergency situations can be solved.
2. The new application of the mobile phone is increased, and when the mobile device serves as more and more comprehensive functions in life, new possibility and replacement are added to the functions of the mobile phone.

FIG. 2 is a diagram of the power circuit board wiring components of the present invention;
fig. 3 is a schematic diagram of outlet line connections.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
Directly adhering a power supply circuit board to a mobile phone backboard, installing an electric quantity output port as a new USB interface on the side surface of the mobile phone, and covering the electric quantity output port by using an adhering piston; as shown in fig. 1, the power supply circuit board includes a battery cell respectively connected to a boost circuit and a charging circuit, the boost circuit is connected to an input terminal, the charging circuit is connected to an output terminal, the input terminal is connected to an input port of the mobile phone, and the output terminal is connected to an electronic device to be charged.
The power supply circuit board is a circuit board for supplying electric quantity to the outside for the mobile phone, and is similar to the circuit board of the charger, and a detailed circuit diagram is shown in fig. 2, wherein a power supply part U1 and a mobile phone battery are two separated batteries, and the electric quantity transfer is realized by the switch of the circuit diagram.
Fig. 3 is a schematic diagram of the connection of the output port line, which is the same as a common data line interface, wherein: 1 is a 5V positive electrode, 2 is a data negative line, 3 is a data positive electrode, and 4 is a 5V negative electrode.
FIG. 2 is described in detail below:
in fig. 2, 1MS is a toggle switch: dialing up as illumination.
The middle gear is a lighting disconnection position and a charging position, and the charger is charged downwards to output and supply the power lamp. LEDs 4 to 7 are high-luminance light-emitting diodes used for illumination. The LED2 green LED serves as a battery charge indicator. LED3 is used for power monitoring indication and illumination when charging by mains.
The switching power supply part U1 adopts NcP1000P integrated circuit pin data, wherein the pin is vcc, the pin is feedback, the pin is ground, the pin is starting voltage input, and the pin is loop. U2EL817 is a photoelectric coupler, and U3TL431, U1 NCP1000P and U2EL817 form a voltage stabilizing circuit.
When the electric quantity of other electronic equipment, such as another mobile phone, is exhausted, a data line is used for connecting with the equipment, one end of the data line is connected with the special interface, and the other end of the data line is connected with the interface of the mobile phone without the electric quantity.
