Embodiment
Referring to accompanying drawing 1, a kind of multi-functional commercial charger comprises charge power supply power supply unit, charging output unit and emergency light unit.Described charge power supply power supply unit is made of four branches, and what the 220V/50HZ of first ac conversion circuit adopted is the PWM control technology, adopts the transformation technology of isolating fully to convert the required low pressure 5V DC power supply of charging circuit to.Second portion adopts automobile-used 12V DC power supply to convert the required low pressure 5V DC power supply of charging circuit to through change-over circuit.Third part adopts 2 joint No. 7 dry cells (chargeable No. 7 Ni-MH batteries) DC power supply to convert the required low pressure 5V DC power supply of charging circuit to through change-over circuit.The 4th part is adopted built-in 4.2V lithium battery DC power supply and is converted the required low pressure 5V DC power supply of charging circuit to through change-over circuit.Described charging output unit is made up of two parts, is the golden finger charging inlet of manual adjustments charging room distance but first adopts, and second portion is to do the USB power supply by the USB Power Block of a standard.Described charger is provided with the LED emergency flashlight as the emergency light unit, and described LED emergency flashlight is connected with described reserve charge power supply by drive circuit.
The practical circuit of multi-functional commercial charger of the present utility model is as shown in Figure 2:
The alternating current that frame of broken lines A partly is mainly used in 220 volts becomes 5 volts direct current through the PWM control transformation, and the battery charge of level and USB power supply are used later on;
Frame of broken lines C partly is mainly used in and power supply on vehicle is changed into 5 volts direct current, and the battery charge of level and USB power supply are used later on;
Lithium battery and No. 7 dry cells of 2 joints that frame of broken lines D, E two parts are mainly used in 4.2 volts change 5 volts direct current into, and the battery charge of level and USB power supply are used later on;
Frame of broken lines B is that the USB Power Block of a standard is done the USB power supply;
Frame of broken lines F is that auto polarity decision circuitry and battery charge are adjusted circuit.
The concrete course of work below in conjunction with equipment is described further system:
Indoor or have in the environment of alternating current of AC100-240V, this equipment connects the alternating current of AC100-240V, equipment partly converts 5 volts direct current to by circuit A, gives the battery charge and the USB power supply usefulness of back level, and can give the built-in lithium cell charging of equipment simultaneously.
