Description

A kind of solar recharging knapsack
Technical field
The utility model is related to case field, more particularly to a kind of solar recharging knapsack.
Background technology
Solar recharging knapsack allows masses to be familiar with so as to victory, environmental protection, energy-conservation, the design concept of low-carbon (LC), while being also family Outer travelling fan and often work are gone on business the essential product of personage, it is adaptable to various style mobile phones, MP3, MP4, digital camera, The electronic products such as IPAD, IPOD.Solar recharging knapsack is changed by solar panel absorption solar energy and by solar energy It is electric energy, according to interface different in bag, is charged to a variety of mobile phones or electronic product.
The charging modes design of current most of solar recharging knapsacks is built-in charging, although this being designed with is beneficial to Solar charging device more good berth, but also to knapsack user bring inconvenience, such as when user has phone incoming call or connects Information is received, user needs to open knapsack, could use electronic product.
Electric current when solar recharging knapsack charges is constant, will not be become with the change of solar energy power output Change.But, when solar energy power output is very low, cause solar recharging knapsack to stop filling due to constant electric current cannot be provided Electricity, and work as solar energy power output and uprised and reopen again charging.Present part smart mobile phone, such as iphone mobile phones, With battery protection function, manual plug charging connector is needed just to reopen charging after midway of charging stops.This causes Prior art solar recharging knapsack cannot be generally applicable to various electronic products charging, by the solution party of integrated battery Case will cause cost to roll up.
Utility model content
The purpose of this utility model is directed to existing technology and there is above mentioned problem, there is provided a kind of simple operation, structure Simply, energy-conserving and environment-protective, a kind of solar recharging knapsack with low cost.
In order to realize goal of the invention, a kind of solar recharging knapsack of the utility model, including inclusion and solar panel. Solar panel is flush-mounted in the outer layer of inclusion, can directly receive light direct projection.The output end of solar panel extends one and wraps Inside paint electric wire to inclusion, and connect one from the USB output modules restarted.A USB extended lines, USB extensions are additionally provided with inclusion The male end of line is connected with USB output modules, and female mouth end of USB extended lines is extended to outside inclusion from the side of inclusion.
The USB output modules include MCU control circuit and the switching power circuit, the USB output circuits that are sequentially connected, The control signal output of MCU control circuit is connected with the enable pin of switching power circuit.MCU control circuit includes being sequentially connected 5V transformations chip and MCU chip.The output voltage decompression of solar panel is 5V and supplies MCU chip by 5V transformations chip Work is used.When MCU chip reaches setting time to electrically continuous work, the PWM pin of MCU chip are restarted and are output control signals to Switching power circuit.
USB output circuits include mu balanced circuit and HUB control circuits, for filling for the terminal output stabilization to USB mother's mouths Piezoelectric voltage.
The switching power circuit includes switching power source chip, the EN pin of switching power source chip and the control of MCU control circuit Signal output part connection processed, the SW pin connection USB output circuits of switching power source chip are simultaneously after electric resistance partial pressure by output voltage The FB pin of feedback signal connecting valve power supply chip.HUB control circuits include HUB control chips.
A kind of solar recharging knapsack of the utility model is provided with the USB output modules in inclusion, while being provided with USB extensions Line, meets user and the electronic products such as charger baby is put in the use needs charged in inclusion, also meets user while using Mobile phone is while the demand for charging.A kind of USB output modules of solar recharging knapsack of the utility model possess restarts function automatically, When solar panel cannot provide the voltage output of stabilization, charging voltage output is thoroughly cut off by MCU control circuit;When When solar panel provides the voltage output of stabilization, output charging voltage is restarted automatically, without integrated battery, without passing through Manual plug plug is realized to the recharged of electronic product.A kind of solar recharging knapsack of the utility model has universal fitting With scope, stable performance is with low cost, simple operation, simple structure.
