Description
Technical field
The present invention relates to a kind of dc charger, especially relate to a kind of collapsible thin-film solar cells dc charger.
Background technology
Along with the arrival in electronic information epoch, the kind of electronic product is more and more, and function is also more and more complete, and people also often face the not enough invasion of powered battery when enjoying electronic product diversification service.
With the mobile phone is example, and at present the 3G communication network is promoted, and cell-phone function is very powerful, as: take pictures, play, online, video playback etc., this just requires mobile phone screen increasing, meanwhile also causes the power consumption of mobile phone soaring rapidly.The demand of stand-by time develops into a kind of common requirements gradually.The length of cell phone standby time largely depends on the performance of battery, and battery technology does not have important breakthrough in a short time, and fuel cell also has a segment distance from practical application.If prolong the cell phone standby time, will cause the portability of mobile phone to descend to increase the battery volume.People need charging device easy to use whenever and wherever possible.
Using solar charger, is an effective way of replenishing battery electric quantity.At present a lot of about the product and the patent of solar charger, but mostly be faced with common disadvantage: and the polysilicon solar cell plate is generally adopted in (1), and toughness is bad, damages easily; (2) the solar panel area is little, and generating capacity is limited; (3) generating capacity of common polysilicon solar cell is responsive to light intensity, and electricity conversion is very low when indoor, even outdoor, the polysilicon solar cell plate is blocked by object slightly, and generating efficiency descends many immediately.The problem of these exist actuallies has seriously hindered the popularization and the application of solar charger.
Summary of the invention
The object of the invention is exactly to provide a kind of durability high, the convenient collapsible thin-film solar cells dc charger that uses for the defective that overcomes above-mentioned prior art existence.
The object of the invention can be realized through following technical scheme:
A kind of collapsible thin-film solar cells dc charger; It is characterized in that; Comprise thin-film solar cell panel, AC/DC ac-dc conversion circuit, storage battery, DC/DC DC transfer circuit, microcontroller and LED lamp; Described thin-film solar cell panel is located at the front of charger and all around, is made up of a main solar panel and four peripheral solar panels, and peripheral solar panel is connected with main solar panel through folding lead; Described LED lamp is located at the top of charger, and described storage battery, AC/DC ac-dc conversion circuit, DC/DC DC transfer circuit, microcontroller are located in the charger.
Described thin-film solar cell panel is amorphous silicon thin-film solar cell or dye-sensitized film solar cell.
Described thin-film solar cell panel is connected with storage battery through the DC/DC DC transfer circuit.
Described storage battery links to each other with DC/DC DC transfer circuit, AC/DC AC transform circuit and LED lamp respectively through microcontroller.
Compared with prior art, the present invention has the following advantages:
(1) the thin-film solar cell panel environmental pollution of adopting is little; Has low light level power generation characteristics; Even also have a higher relatively electricity conversion indoor, at the bottom of flexible stainless steel lining, polymer laminate; Component package has adopted the UV cure polymer, and this encapsulation polymer mainly comprises EVA and fluoropolymer ETEE.In light weight, pliability is good, impact resistance, anti-ly step on, anti-falling, be difficult for breaking; Protection against the tide, durability is high.
(2) thin-film solar cell panel is collapsible, when going out solar panel is folded up, and is easy to carry; When the needs electric energy supplement, directly the solar cell plate development is got final product, when charger leaves unused; Can be with four solar cell plate developments; Be tiled in desktop, also can be used as support charger is supported on the table, more fully to experience light.The generating capacity of the solar panel that the utility model designed is 5 times of regular solar charger at least.
(3) have solar energy and civil power two cover energy input devices concurrently, when light is strong, can preferentially use luminous energy that storage battery is directly charged, when light is more weak, also can use civil power to charge.
(4) integrate illumination and charge function, both can be used as charger and directly battery has been carried out DC charging, improve charging rate, also can be used as illuminations and use, satisfy people's demand easy to use.
(5) adopt microcontroller to monitor the charging and discharging of accumulator state, when battery charging and discharging arrives predetermined threshold, just cut off the function that discharges and recharges of battery automatically, play the effect that prolongs the energy-storage battery life-span.
