Accompanying drawing explanation
Fig. 1 is side sectional view of the present utility model.
Fig. 2 is the circuit theory diagrams of charging circuit.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in more detail.
The utility model discloses a kind of multifunctional solar cap, as shown in Figure 1, it includes cap body 1 and sunshade 2, sunshade 2 is provided with fan 6, the outer surface of cap body 1 is provided with solar cell 3, charging circuit 4 and rechargeable battery 5, solar cell 3 is by 5 chargings of 4 pairs of rechargeable batteries of charging circuit, and rechargeable battery 5 provides power supply for fan 6.Wherein, under the strong condition of sunlight, solar cell 3 is by 5 chargings of 4 pairs of rechargeable batteries of charging circuit, make rechargeable battery 5 store enough electric energy, when light dies down and when the light energy conversion efficiency of solar cell 3 reduces, rechargeable battery 5 is sustainable provides electric energy to fan 6, makes fan 6 can access long electric power supply.
In the present embodiment, solar cell 3 is positioned on cap body 1 side near sunshade 2, and charging circuit 4 and rechargeable battery 5 are positioned on cap body 1 side away from sunshade 2.Wherein, solar cell 3 has larger area and is layed in the upper surface of cap body 1, thereby obtains better light.
In order to realize charge function, shown in Fig. 1 and Fig. 2, charging circuit 4 includes pwm chip U1, inductance L 1, NPN pipe Q1 and voltage-stabiliser tube D1, the voltage of solar cell 3 output provides power supply for pwm chip U1, the output head anode of this solar cell 3 is connected in the anode of voltage-stabiliser tube D1 by inductance L 1, the negative electrode of voltage-stabiliser tube D1 is connected with the positive pole of rechargeable battery 5, this solar cell 3 and rechargeable battery 5 are altogether, inductance L 1 is also connected in the tie point of voltage-stabiliser tube D1 the colelctor electrode that NPN manages Q1, the grounded emitter of this NPN pipe Q1, the pulse output end SW of pwm chip U1 is connected in the base stage of NPN pipe Q1 by current-limiting resistance R1, between the negative electrode of voltage-stabiliser tube D1 and ground, be connected with resistance R 2 and the resistance R 3 of connecting successively, the Voltage Feedback of resistance R 2 and resistance R 3 tie points returns the feedback end FB of pwm chip U1, between the negative electrode of voltage-stabiliser tube D1 and ground, be also connected with filter capacitor C1.
The operation principle of above-mentioned charging circuit 4 is: the feedback end FB of pwm chip U1 samples to the voltage of resistance R 2 and resistance R 3 tie points, when the output voltage of rechargeable battery 5 reduces, pwm chip U1 output low level signal is to make NPN pipe Q1 cut-off, the output voltage of solar cell 4 charges to rechargeable battery 5 by inductance L 1 and voltage-stabiliser tube D1, and voltage-stabiliser tube D1 now plays afterflow effect; When the output voltage of rechargeable battery 5 is higher or reach full power state, pwm chip U1 output high level signal is to make NPN pipe Q1 conducting, now, solar cell 4, inductance L 1 and NPN pipe Q1 form loop, inductance L 1 charging, meanwhile, rechargeable battery 5, voltage-stabiliser tube D1 and NPN pipe Q1 form loop, voltage-stabiliser tube D1 reverse breakdown and its negative electrode arrive preset value by voltage stabilization, to make fan 6 obtain stable voltage; Along with the running of fan 6 and the energy consumption of rechargeable battery 5, when the voltage of rechargeable battery 5 reduces again, the feedback end of pwm chip U1 obtains this signal, thereby driving N PN pipe Q1 cut-off, after the output voltage of the voltage that inductance L 1 is stored and solar cell 4 is superimposed, with higher voltage, to rechargeable battery 5 quick charges, until this rechargeable battery 5 is full of, pwm chip U1 again driving N PN manages Q1 conducting.Repeatedly, fan 6 can obtain electric power supply for a long time.
