Description

A kind of solar energy constant charge device
Technical field
It the utility model is related to a kind of charging device, and in particular to a kind of solar energy constant charge device.
Background technology
With the portable type electronic product such as development and the improvement of people's living standards, mobile phone, PDA, digital camera of science and technology Use in people live is more prevalent, or even has become the indispensable part of people's daily life.Portable electric The use of sub- product is usually to provide electric energy by battery, because the charge storage ability of battery is limited, after certain time, just Need to change battery or battery is charged using charger.
Existing charger is that secondary cell is charged using civil power (AC100V-240V) as charge power supply mostly 's.This, in long-time field work or outdoor travel, is made troubles to people using electronic product.
Existing many improving countermeasures regarding to the issue above, such as carry with charger baby power supply or solar charger charging Deng.It is very universal with charger baby power supply, but the finite capacity of charger baby, it can only temporarily meet an urgent need, also just use up quickly.Often The solar charger of rule(Such as a kind of 201410546193.0 solar chargers and 201110087642.6 solar rechargings Device)Because the factor changed by Intensity of the sunlight is influenceed, output voltage electric current less stable;To electric current than more sensitive Electronic product such as iphone5s etc. can prompt error message when above using when sensing charging current and changing, and user can worry certainly Oneself electronic product is impaired and abandons using these conventional solar chargers.
Utility model content
Its purpose of the utility model, which is that, provides a kind of solar energy constant charge device, solves regular solar charger Because the factor changed by Intensity of the sunlight is influenceed, cause output voltage electric current less stable, more sensitive to electric current Electronic product on use when can exist sensing inductive charging curent change when prompt error message the problem of.
The technical scheme realized above-mentioned purpose and taken, a kind of solar energy constant charge device, including solar battery group, control Molding block, described control module one end connect solar battery group, control module other end connection rechargeable battery, control module Output interface is provided with, the control module includes voltage stabilizing chip, and voltage stabilizing chip one end connects the positive pole of solar battery group, surely The pressure chip other end point switched through 2# all the way, the positive pole of rechargeable battery, the voltage stabilizing chip other end point are connected to after 2# diodes Switch all the way through 1#, the positive pole of rechargeable battery is connected to after 1# diodes, the voltage stabilizing chip other end point is sequentially connected in series electricity all the way Be connected to the positive pole of output interface after flow table, current limiting switch and 3# switches, the solar battery group and rechargeable battery it is negative Extremely it is connected with the negative pole of output interface.
Beneficial effect
The utility model has advantages below compared with prior art.
The utility model has the advantages that the voltage and current ratio that solar recharging system exports to electronic product can be ensured It is relatively stable, so as to protect the electronic product for charging, improve the CSAT of solar recharging system.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the electric principle schematic of control module in the utility model.
Embodiment
The present apparatus includes solar battery group 1, control module 2, as shown in Figure 1 and Figure 2, the one end of control module 2 connection Solar battery group 1, the other end of control module 2 connection rechargeable battery 3, control module 2 are provided with output interface 4, the control Molding block 2 includes voltage stabilizing chip 21, and the one end of voltage stabilizing chip 21 connects the positive pole of solar battery group 1, the other end of voltage stabilizing chip 21 Divide the positive pole for being connected to rechargeable battery 3 after 2# switchs 24,2# diodes 25 all the way, the other end point of voltage stabilizing chip 21 passes through all the way The positive pole of rechargeable battery 3 is connected to after 1# switches 22,1# diodes 23, the other end point of voltage stabilizing chip 21 is sequentially connected in series electricity all the way It is connected to the positive pole of output interface 4 after flow table 26, current limiting switch 27 and 3# switches 28, the solar battery group 1 and chargeable Negative pole of the negative pole of battery 3 with output interface 4 is connected.
The current limiting switch 27 is the internal TPS2041 series productions with mos field effect transistor Product.
The cathode terminal of 2# diodes 25 is connected with the positive pole of rechargeable battery 3, the anode tap of 1# diodes 23 with can The positive pole of rechargeable battery 3 is connected.
Solar battery group 1 is connected with control module 2 in the utility model, control module 2 respectively with rechargeable battery 3 and Output interface 4 connects.It is steady in control module 2 when solar battery group 1, which is in, converts solar energy into electric energy under sunshine The electric energy voltage stabilizing that pressure chip 21 exports solar battery group 1 is 5V, and 3# switches 28 close;When the feedback line electric current of ammeter 26 During more than 1A, the closure of 2# switches 24, solar battery group 1 charges to rechargeable battery 3 simultaneously, and current limiting switch 27 is by output interface 4 electric current is limited to 1A;When intensity of illumination die down the feedback line electric current of ammeter 26 be less than 1A when, 2# switch 24 disconnect simultaneously 1# The closure of switch 22, solar battery group 1 and rechargeable battery 3 are powered to output interface 4 simultaneously, and current limiting switch 27 is by output interface 4 electric current is limited to 1A;When the disconnection of 2# switches 24 and 1# switches 22 close and the feedback line electric current of battery table 26 is less than 1A, 1# Switch 22 and 3# switches 28 to disconnect, the closure of 2# switches 24;Output interface 4 stops external output current, and solar panel 1 is only given can Rechargeable battery 3 charges, and after the electricity of rechargeable battery 3 runs up to a certain amount of, 2# switches 24 disconnect 1# simultaneously and switch 22 Hes The closure of 3# switches 28, solar battery group 1 and rechargeable battery 3 are powered to output interface 4 jointly, and current limiting switch 27 connects output The battery of mouth 4 is limited to 1A;When solar battery group 1 does not receive enough illumination, but output interface 4 has sensed electronics production When product access, 1# switchs 22 and 3# switches 28 and is closed at, and is powered by rechargeable battery 3, if the feedback line electric current of ammeter 26 Less than 1A, then 3# switches 28 disconnect, and output interface 4 stops supplying power for outside;The current limliting if the feedback line electric current of ammeter 26 is more than 1A The battery of output interface 4 is limited to 1A supplying power for outside by switch 27.
