Description
Technical field
The utility model relates to a kind of charger, especially a kind of solar charger.
Background technology
Under the international overall situation, just progressively popularize green energy resource.Along with numerous semiconductors such as germanium, silicon, GaAs are employed, new forms of energy also will replace the parts of traditional energy.In the desert, grassland, highlands, travelling is medium does not have under the common charge power supply condition, also is the problem that needs solve for small electric apparatus chargings with oneself such as mobile phones how.
Existing solar charger generally includes critical pieces such as solar battery sheet, control circuit, internal battery, charging inlet, its control circuit is generally bridge rectifier and is converted to direct current behind capacitor filtering, major defect is the electric circuit construction complexity, and cost is higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of solar charger simple in structure, lower-cost is provided, and is used to not have under the common charge power supply condition compact electric apparatus is charged.
The technical scheme that provides according to the utility model, described solar charger, comprise a plurality of solar battery sheets that are in parallel, charging inlet, anti-recoil diode, electric capacity, the positive and negative electrode of described a plurality of solar battery sheets is electrically connected with the both positive and negative polarity of described electric capacity respectively, the positive pole of described solar battery sheet is connected with the positive electrical of described anti-recoil diode simultaneously, the negative pole of described anti-recoil diode is electrically connected with first pin of charging inlet, and second pin of described charging inlet is connected with the negative electricity of described solar battery sheet.
As preferably, also be connected with the divider resistance and the saturation condition indicator light of series connection between the negative pole of described anti-recoil diode and the negative pole of solar battery sheet.
Described charging inlet is general-purpose interface or special purpose interface and/or USB interface.
As preferably, described a plurality of solar battery sheets that are in parallel are 8, and the output voltage of every battery sheet is 0.5 volt.
As preferably, be connected in parallel to rechargeable battery at the positive and negative end of described solar battery sheet.
Compared with prior art, the utility model energy-conserving and environment-protective, its electronic circuit constitutes by simple components, and existing relatively charger is simple in structure, does not have complicated integrated circuit, the cost performance of product height.
Description of drawings
Fig. 1 is the utility model circuit theory diagrams.
Fig. 2 is the user mode figure of the utility model when connecing rechargeable battery.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1: this solar charger comprises solar battery sheet group SL1, SL2 in parallel, charging inlet, anti-recoil diode VD1, capacitor C 1.The positive and negative electrode of a plurality of solar battery sheets is electrically connected with the positive and negative electrode of capacitor C 1 respectively, the positive pole of solar battery sheet and the positive pole of anti-recoil diode VD1 are electrically connected simultaneously, first pin of the negative pole of anti-recoil diode VD1 and charging inlet is electrically connected, second pin of charging inlet and solar battery sheet SL1, the negative pole of SL2 is electrically connected.Capacitor C 1 has a constant impedance, anti-battery sheet both positive and negative polarity short circuit, and entire circuit is still series system.Solar battery sheet sheet number is 8 altogether, and the output voltage of every battery sheet is 0.5 volt.
Also be connected with the divider resistance R1 and the saturated indicator light LED of series connection between the negative pole of anti-recoil diode VD1 and the negative pole of solar battery sheet, be used to judge whether the battery of small electric apparatus to be charged such as mobile phone is in saturation condition.
Charging inlet of the present utility model can be general-purpose interface, special purpose interface or many interfaces.It is small electric apparatus chargings such as mobile phone that general-purpose interface can be used as universal charger, as having USB interface simultaneously, then when being cell-phone charging, can realize many interface functions for the charging of digital products such as mp3, mp4, mp5 again.
As run into rainwater, night etc. during no sunlight, can be connected in parallel at the positive and negative end of solar battery sheet increases the rechargeable battery of a 4.5V, is small electric apparatus chargings such as mobile phone by this battery, as shown in Figure 2.
The utility model and existing charger have relatively been eliminated complicated electronic circuit such as bridge rectifier, filter circuit in the existing charger, only use simple electronic devices and components to get final product direct output of DC current, and circuit structure is simple, and the product price ratio is higher.
