Abstract
The utility model relates to a combined product of the original AA rechargeable battery, charging circuit and USB interface, which is characterized in that the negative end of the original rechargeable battery is shortened about 20 mm, and a charging control chip and a standard USB interface are arranged in the 20 mm space, wherein, a charging indicating lamp is arranged on the charging control chip; a pole cap is arranged outside the USB interface; the size of the product with the pole cap is totally uniform with the standard size of the AA battery, therefore, the product allows to be used as a common battery. The utility model has the advantages that the combined product enables to charge directly with the USB interface when in travel, and the inconvenience of carrying a charger is avoided.
Description
Technical field
The utility model relates to a kind of AA rechargeable battery of USB interface, it belongs to a kind of improvement to existing rechargeable battery, make new product that power supply but also can be not by other charging device not only can be provided, directly charge, increased the ease for use and the portability of original rechargeable battery by USB interface.
Background technology
Traditional AA rechargeable battery extensive use in all kinds of digital products, yet when travelling outdoors particularly long-distance travel, need be its charging unavoidably by charger, charger had just become extra weight to increase a little inconvenience for travelling after charging was finished, and left behind the incident of charger often.The purpose of this utility model is exactly that the function that charger is realized directly is integrated in the battery in order to solve this inconvenience, just can replenish for battery carries out electric power by the USB interface of standard.
Summary of the invention
The utility model is characterized in that original AA rechargeable battery, the combination of charging circuit and USB interface, thus the product of combination can directly be charged by USB interface, remove from and carry the inconvenient and worried of charger.
It is characterized in that adopting standard USB interface, adopt miniature charge controlling chip that the electric power that USB interface provided is filled in the rechargeable battery, and the indication that provides charging whether to finish.About about 1000mA, with the electric current calculating of 200mA that USB interface is provided, be full of a joint AA battery approximately needs about 5 hours to the capacity of rechargeable battery greatly.

Embodiment
As shown in Figure 2, the utility model by 4 most of compositions is respectively: 1. battery body; 2. control chip; 3.USB standard interface; 4. negative pole interface cap.USB interface is connected with control chip in the utility model, and main control chip adopts very ripe LTC4055 power management module, and the connection of control chip and circuit thereof as shown in Figure 3.Control chip outputs to battery body with charging current, and what battery body adopted is the Li ion battery, and it is higher to compare its energy density of traditional battery material, does not have memory effect, can remedy electrolyte and reduce and the battery capacity of loss.
During charging, take off negative pole interface cap, insert USB interface, indicator light becomes orange, and battery begins charging, and indicator light becomes the green mark charging and finishes.
During use, put on negative pole interface cap, its overall dimensions are identical with standard A A battery, can normally use.
Claims (2)
1. USB interface rechargeable battery, be to rechargeable battery, charging circuit, being linked in sequence of USB interface and negative pole interface cap, it is characterized in that: rechargeable battery is anodal to be connected with charging circuit one side with negative pole, the charging circuit opposite side is connected with USB interface, and negative pole interface cap is connected with the rechargeable battery negative pole and can covers USB interface fully.
2. USB interface rechargeable battery according to claim 1, it is characterized in that: the rechargeable battery part, the charging circuit part, the external diameter of negative pole interface cap portion is identical with AA battery external diameter, and its length sum was identical with AA battery length after above-mentioned three parts were installed together.
