Description
Technical field
The utility model belongs to the charging technique field, relates in particular to a kind of portable charger.
Background technology
At present, various mobile electronic devices and people's life is more and more tightr, as MID (Mobile InternetDevice mobile internet device), mobile phone etc., it not only provides the facility of communication for people, functions such as the Internet access, amusement, recreation also are provided for people, therefore, people use the time of mobile electronic device can be more and more longer, and the problem of being brought is that the electric energy that provides of battery is just more and more not enough.In order to address this problem, people design a lot of ways, as more battery are provided or use more jumbo battery, and the former needs the user constantly to change battery, but the user can't change battery in the process of using mobile electronic device; And jumbo battery stock size can be bigger, and this must cause mobile electronic device can't satisfy the development trend of portability, and therefore, above-mentioned two kinds of schemes all can not well satisfy user's demand.
Because of being not easy to address this problem from the battery aspect merely, being improved to address this problem by the charging device aspect of mobile electronic device just becomes a kind of thinking, but present charging device all is the DC power supply that the AC power of civil power is converted into low pressure, then battery is charged, but this charging device can only use in the place that AC power is arranged, and under the situation of AC-less power, then can't finish charging to mobile electronic device.
The utility model content
The purpose of this utility model is to provide a kind of portable charger, is intended to solve the problem of charging for mobile electronic device under the situation of civil power not having.
The utility model is to realize like this, a kind of portable charger, comprise transformer and battery charging module, described portable charger also comprises the energy-storage module and first charging module, described energy-storage module one end connects battery charging module, the other end connects first charging module, and described first charging module disposes the interface that is connected with mobile electronic device.
More specifically, be connected by switch between described battery charging module and the described energy-storage module.
More specifically, describedly portablely also comprise the overvoltage detection module that detects described energy-storage module voltage towards electric installation, described overvoltage detection module one end connects described energy-storage module, and the other end connects the control end of described switch.
More specifically, describedly portablely also comprise second charging module towards electric installation, described second charging module, one end connects described battery charging module.
More specifically, the described second charging module other end disposes the interface that is connected with mobile electronic device.
More specifically, described interface is a USB interface.
More specifically, described energy-storage module is a rechargeable battery.
More specifically, described battery is a lithium battery.
The utility model overcomes the deficiencies in the prior art, be provided with energy-storage module in the portable charger that provides, this energy-storage module can the pre-charge energy storage, and when mobile electronic device need charge, the electric energy in the energy-storage module charged to mobile electronic device by charging module.The portable charger that the utility model provides can satisfy user's actual demand to the mobile electronic device charging under the situation of civil power behind the dollar, has improved cost performance of product.

Fig. 2 is the theory diagram of the portable charger of the utility model second embodiment;
Embodiment
Be provided with energy-storage module in the portable charger that the utility model provides, this energy-storage module can the pre-charge energy storage, and when mobile electronic device need charge, the electric energy in the energy-storage module charged to mobile electronic device by charging module.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The theory diagram of the portable charger of the utility model embodiment one comprises transformer, battery charging module, energy-storage module, first charging module and overvoltage detection module as shown in Figure 1.Wherein:
Transformer is connected with battery charging module, can connect civil power (alternating current 220V), and civil power is through the step-down of overvoltage device, to battery charging module output low-voltage AC;
Battery charging module is connected by switch with energy-storage module, converts low-voltage AC to direct current, charges to energy-storage module;
Energy-storage module is connected with first charging module, one end, the first charging module other end disposes the interface that is connected with mobile electronic device, when first charging module is external when needing the mobile electronic device (as mobile phone) of charging, first charging module utilizes the electric energy in the energy-storage module to charge to mobile electronic device;
Overvoltage detection module one end connects energy-storage module, and the other end connects the control end of the switch between battery charging module and the energy-storage module, and when the voltage that detects energy-storage module exceeded setting voltage, control switch disconnected, and avoids overcharging to energy-storage module.
When the user uses the portable charger that the utility model provides, can be at first in the place that civil power is arranged to the energy-storage module charging of portable charger, after energy-storage module had dashed electricity, the user carried portable charger and goes out.If the power consumption when the user goes out in the mobile electronic device finishes, need charging.Under the situation that does not possess mains supply, the portable charger that can adopt the utility model to provide is charged to mobile electronic device by the energy-storage module in the portable charger and first charging module, to satisfy emergent need.
The theory diagram of the portable charger of the utility model embodiment two as shown in Figure 2, the functional module in Fig. 1, the portable charger of embodiment two also comprises second charging module, this second charging module is connected with battery charging module, and the interface that is connected with mobile electronic device of configuration.If the power consumption in user's the mobile electronic device finishes, need charging.Possessing under the situation of mains supply, the portable charger that can adopt the utility model to provide, can directly be charged to mobile electronic device by second charging module this moment by the battery charging module in the portable charger, and do not need to employ the electric energy in the energy-storage module.
Among the utility model embodiment, the interface of portable charger and mobile electronic device can adopt USB interface.Energy-storage module can be jumbo lithium battery.The portable charger that the utility model embodiment provides can charge to mobile electronic devices such as mobile phone, MID, MP3, MP4 and e-book.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
