Description
Technical field
The utility model relates to a kind of charging equipment for mobile phone, and referring more particularly to dry cell is the urgent charger of mobile phone of cell-phone charging.
Background technology
Existing battery of mobile phone all is a rechargeable battery, AC power is generally all adopted in charging to rechargeable battery, yet AC power is not to be seen everywhere, in case mobile phone electric weight deficiency, the cellie must look for a fixing AC power, for the user who is busy with one's work or goes out, often do not had electricity to battery of mobile phone, just remember charging, at this moment also need spend the long time to charge, brought inconvenience to the user, even influenced work, because the voltage of voltage and battery of mobile phone does not meet and can't be used in mobile phone, and dry battery internal resistance is bigger, and stable output voltage can not be provided again for simultaneously general dry cell.
So businessman begins to design quick charger, these quick chargers not only circuit complexity, energy conversion efficiency are low, but also can influence the useful life of battery of mobile phone.
The utility model content
The purpose of this utility model is intended to solve problems such as existing mobile phone quick charger circuit complexity, energy conversion rate are low, provides the mobile phone that a kind of circuit is simple, energy conversion rate is high urgent charger.
The urgent charger of the utility model mobile phone, comprise dry cell, accumulation of energy inductance L, DC voltage converter IC, energy storage capacitor C and diode D, one end of accumulation of energy inductance L is connected with the positive pole of dry cell, the other end is connected with the positive pole of diode D and the input of DC voltage converter IC, the negative pole of diode D is connected the back and is connected with the positive pole of energy storage capacitor C with the output of DC voltage converter IC, and as the output of charger for mobile phone, the equal ground connection of negative pole of the negative pole of dry cell, the earth terminal of DC voltage converter IC, capacitor C.
Be provided with touch-switch K and superbright LED between the described dry cell both positive and negative polarity.
Described diode D is a Schottky diode.
Owing to taked said structure, it is bigger that the utility model has solved dry battery internal resistance, problems such as stable output voltage and existing quick charger circuit complexity, energy conversion rate be low can not directly be provided, use DC voltage converter IC to play burning voltage and electric current, voltage is steady when making cell-phone charging, noiselessness; The unidirectional conducting fast of diode D can be with the electric energy of dry cell rapidly and efficiently in the input handset lithium battery, with time that shortens cell-phone charging and the utilization that improves electric energy; And inductance L and capacitor C are the effect of accumulation of energy.
The utility model is owing to also be provided with LED and touch-switch K between dry cell and ground, so when darkness does not have lamp, the function that also has flashlight, therefore the utlity model has that circuit is simple, quick the electric energy of dry cell, high efficiency is thoroughly transferred in the cellular li-ion battery, and noiselessness, output voltage is steady and characteristics such as multi-functional.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the circuit theory diagrams of the utility model embodiment.
Embodiment
Embodiment one, and as shown in Figure 1, the urgent charger of the utility model mobile phone comprises the dry cell V of 4.5V
In, 50 μ h accumulation of energy inductance L, ME501 DC/DC DC voltage converter IC, 30 μ F energy storage capacitor C, 5818/5819 Schottky diode D, the accumulation of energy inductance L is connected on the anodal V of dry cell
InAnd between the DC voltage converter IC input, the output of DC voltage converter IC is connected with capacitor C with 4.2V cellular li-ion battery Vout, the positive pole of diode D connects the input with DC voltage converter IC, and its negative pole connects the output with DC voltage converter IC, dry cell V
InNegative pole, DC voltage converter IC, capacitor C, the equal ground connection of negative pole of cellular li-ion battery Vout, dry cell V
InBe provided with touch-switch K and superbright LED between the positive and negative electrode, the bullet that touch-switch K still has bullet hooked hand machine transplanting of rice head simultaneously colludes switch.
During use, DC voltage converter IC plays burning voltage and electric current, and voltage is steady when making cell-phone charging, noiselessness; The unidirectional conducting fast of diode D can be with dry cell V
InElectric energy rapidly and efficiently in the input handset lithium battery Vout, with time that shortens cell-phone charging and the utilization that improves electric energy; And inductance L and capacitor C are the effect of accumulation of energy.
Also be provided with LED and touch-switch K between the dry cell positive and negative electrode, so when darkness did not have lamp, the utility model also had the function of flashlight, so the utility model provides convenience for the user who is busy with one's work, goes out or travel.
