Description
[technical field]
The utility model relates to a kind of supply unit, particularly relates to a kind of portable power source for mobile digital equipment charge.
[background technology]
Portable power source a kind ofly integrates power supply and the portable charger of charge function, can charge whenever and wherever possible or standby power to digital equipments such as mobile phones, generally by lithium cell or dry cell as charge storage unit.Be different from the battery of interiors of products configuration, be also externally hanging battery.General outfit multiple power sources adapter, usually having Large Copacity, multipurpose, volume is little, the life-span is long and the feature such as safe and reliable, is whenever and wherever possible for the multiple digital products such as mobile phone, MP3, MP4, PDA, handheld device are powered or the functional product of standby charging.
But the most volume of current portable power source is comparatively large, carries inconvenience, and also easily spontaneous combustion occurs when battery is short-circuited, cause security incident, more crucially most of portable power source all only has a USB output interface and can not realize discharge and recharge simultaneously.
In view of this, necessaryly provide a kind of portable power source to solve the problems of the technologies described above.
[utility model content]
The purpose of this utility model is the defect in order to overcome above-mentioned existing portable power source, provides a kind of structure simple, designs ingenious and can prevent the portable power source of spontaneous combustion.
To achieve these goals, the utility model provides a kind of portable power source, it comprises aluminium and adds Zinc alloy electroplating housing, the energy storage of high-capacity lithium ion battery polymer battery core is provided with in described housing, IC discharge and recharge chip, DC-DC voltage up converting circuit, battery core protective circuit and control circuit board, the side of described housing is provided with two USB output interfaces and Micro input interface, the surface of described housing is provided with battery capacity indication lamp and mains switch, described USB output interface, Micro input interface, battery capacity indication lamp, mains switch, DC-DC voltage up converting circuit and battery core protective circuit are all electrically connected with control circuit board.
One as the utility model portable power source is improved, and the capacitance of described high-capacity lithium ion battery polymer battery core energy storage is 6000mAh.
One as the utility model portable power source is improved, and described battery capacity indication lamp is 4 brightness blue light LED.
One as the utility model portable power source is improved, and described USB output interface, Micro input interface are arranged at the homonymy of housing, and Micro input interface is positioned in the middle of two USB output interfaces.
Compared with prior art, the benefit that the utility model portable power source has is: 1) can realize discharge and recharge simultaneously; 2) charge condition of portable power source is judged in time by battery capacity indication lamp; 3) aluminium adds the spontaneous combustion that Zinc alloy electroplating housing can prevent portable power source from occurring because of unexpected.
[accompanying drawing explanation]
Fig. 1 is the three-dimensional exploded view of the utility model portable power source.
[embodiment]
In order to make, the purpose of this utility model, technical scheme and Advantageous Effects are more clear to be understood, below in conjunction with the drawings and specific embodiments, is further elaborated to the utility model.Should be understood that, the embodiment described in this specification is only used to explain the utility model, is not to limit the utility model.
Please refer to shown in Fig. 1, the utility model provides a kind of portable power source, comprise aluminium and add Zinc alloy electroplating housing, high-capacity lithium ion battery polymer battery core energy storage 10 is provided with in described housing, IC discharge and recharge chip, DC-DC voltage up converting circuit, battery core protective circuit and control circuit board, the side of described housing is provided with two USB output interfaces 11 and Micro input interface 12, the surface of described housing is provided with battery capacity indication lamp 13 and mains switch 14, described USB output interface 11, Micro input interface 12, battery capacity indication lamp 13, mains switch 14, DC-DC voltage up converting circuit and battery core protective circuit are all electrically connected with control circuit board.
Housing comprises upper cover 21 and lower cover 22; wherein; lower cover 22 is rectangular underframe shape structure; the central authorities of described frame-shaped structure form a receiving space; described high-capacity lithium ion battery polymer battery core energy storage 10, IC discharge and recharge chip, DC-DC voltage up converting circuit, battery core protective circuit and control circuit board are all contained in this receiving space, the rectangular lid platy structure of upper cover 21.
Be provided with three depressed parts in the same side of described lower cover 22, in described depressed part, be respectively equipped with USB output interface 11 and Micro input interface 12, and Micro input interface 12 is positioned in the middle of two USB output interfaces 11.
The utility model provides a kind of portable power source; this portable power source employs wisdom IC discharge and recharge chip; have and fill while the function of putting, and the lithium cell protective circuit arranged can control circuit realize that precise voltage overcharges, voltage cross put, current overload, short-circuit protection and temperature protection.The capacitance of the high-capacity lithium ion battery polymer battery core energy storage that the utility model adopts is 6000mAh.
The utility model portable power source, be not restricted to described in specification and execution mode, therefore additional advantage and amendment can easily be realized for the personnel of familiar field, therefore when not deviating from the spirit and scope of the universal that claim and equivalency range limit, the utility model is not limited to specific details, representational equipment and illustrates here and the examples shown described.
