Abstract
The utility model provides a mobile power supply comprising a shell body, a power supply body positioned in the shell body, a power supply input interface, and a power supply output interface. The power supply input interface and the power supply output interface are respectively connected with the power supply body. The power supply body is provided with a switch which is connected with the power supply body and is used for controlling on and off states of the power supply body. The utility model has the following advantages that: an electronic device is powered by the mobile power supply, thus the electronic device always maintains sufficient electrical quantity, and charging of the electronic device is very convenient.
Description
Technical field
The utility model relates to power supply, relates in particular to portable power source.
Background technology
Existing electronic equipment is more and more; Also more and more advanced, the power consumption of electronic equipment is also increasing simultaneously, and for example mobile phone is in the process of carrying; Because mobile phone uses for a long time; So that mobile phone is easy to cause the not enough situation of electric weight, the traditional approach that still is to use charger to charge to the charging modes of mobile phone at present, but this charging modes is very inconvenient.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of portable power source.
The utility model provides a kind of portable power source, the power supply body, power input interface, the electric energy output interface that comprise housing and be positioned at said enclosure interior, and said power input interface links to each other with said power supply body respectively with said electric energy output interface; This housing is provided with switch, and said switch links to each other with said power supply body and is used to control the on off state of power supply body.
As the further improvement of the utility model, said switch is a contact witch.
As the further improvement of the utility model, said housing also is provided with the display unit that shows electric weight and voltage.
As the further improvement of the utility model, said power supply body comprises control circuit and the electrical energy storage device that links to each other with said control circuit.
As the further improvement of the utility model, said control circuit also comprises overcharge protection circuit and over-discharge protection circuit.
As the further improvement of the utility model, said control circuit also comprises short-circuit protection circuit and current foldback circuit.
As the further improvement of the utility model, said electric energy output interface is a USB interface.
The beneficial effect of the utility model is: through this portable power source is power electronic equipment, makes electronic equipment remain sufficient electric weight, and charges very convenient for electronic equipment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model discloses a kind of portable power source; The power supply body, power input interface 5, the electric energy output interface that comprise housing 1 and be positioned at said housing 1 inside, said power input interface 5 links to each other with said power supply body respectively with said electric energy output interface; This housing is provided with switch 2, and said switch 2 links to each other with said power supply body and is used to control the on off state of power supply body.
Said power supply body comprises control circuit and the electrical energy storage device that links to each other with said control circuit.
Is the portable power source charging through power input interface 5, and with power storage in electrical energy storage device; Link to each other with power consumption equipment through electric energy output interface, for example link to each other, for cell-phone charging provides electric energy with mobile phone.Because this portable power source can be carried, so use very convenient.
Said switch 2 is a contact witch.Control the operating state of this portable power source through this contact witch, when pressing this contact witch, portable power source is opened, a system works such as can charge; When pressing contact witch once more, this portable power source cuts out, and this portable power source stops the work of going up.
Said housing 1 also is provided with the display unit that shows electric weight and voltage.Can see information such as electric weight last in this portable power source through this display unit user, for the user facilitates.
Said control circuit also comprises overcharge protection circuit and over-discharge protection circuit, and said control circuit also comprises short-circuit protection circuit and current foldback circuit, for this portable power source provides the protection of circuit aspect, guarantees the operate as normal of this portable power source.
Said electric energy output interface is a USB interface 3.This USB interface 3 is two, can be two power consumption equipment chargings simultaneously, and is very practical and convenient.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection range of the utility model.
