Abstract

The utility model provides a portable charging battery which can be carried about. The utility model comprises a battery and a battery box cover, the battery is arranged in a battery box, the both sides of the battery box cover are respectively provided with an output interface whose inner is positive and the external is negative and a charging interface whose inner is positive and the external is positive, and the top part of the battery box cover is provided with a double-knife double-throw toggle switch which is used for selecting a power supply mode of serial connection and parallel connection for two single batteries according to needs. The utility model is beautiful in appearance and convenient in carrying, the utility model can provide a DC power of bigger volumetric capacity than dry batteries or other charging batteries, and the utility model can be used for electric appliances carried during outing.

Description

The portable rechargeable battery

The utility model relates to a kind of battery, especially a kind of portable rechargeable battery.

For some move electrical appliance as miniature radio-tape recorder, books television set, tourism fan cap, small-sized head lamp etc., commercially available primary cell or secondary cell, its capacity is less than normal, the operating time short, when the time of travelling outdoors is long, be difficult to satisfy user's requirement, although possess the direct current input interface, can't use in the travelling.

The purpose of this utility model provides a kind of portable portable rechargeable battery.

The purpose of this utility model is achieved in that it comprises battery 1 and battery case lid 2, battery 1 places in the battery case 9, the lower end of pendant card 4 extends a back-off, the upper end extends two card small circle rings 11 of wearing as hinge, the back side of battery case 9 is put one and is had two battery case small circle rings 10, torsion spring 8 places between two battery case small circle rings 10, two battery case small circle rings 10 place again between two small circle rings of the card 4 of wearing, the size of the small circle ring endoporus of pendant card 4 and battery case 9 and the size of rotating shaft 7 are complementary, one termination diameter of rotating shaft 7 is greater than the endoporus of annulus, the other end of rotating shaft 7 passes the card 4 of wearing simultaneously, behind the small circle ring of battery case 9 and the torsion spring 8, snap in packing ring 6 on the groove of rotating shaft 7 other ends, battery case lid 2 covers battery 1, just outer negative and interior negative outer positive output interface A in the both sides of battery case lid 2 are respectively equipped with, B and charging inlet; The top of battery cover 2 has a dpdt double-pole double-throw (DPDT) toggle switch 3, realizes two cells are selected coupled in series or parallel connection on demand.

The utility model has the advantages that: 1, profile fineness, easy to carry; 2 because of just outer negative, interior negative outer just two output interfaces and dpdt double-pole double-throw (DPDT) toggle switch in having, so the high-quality DC power supply of opposed polarity and different voltages can be provided for electrical appliance; 3 can provide than dry cell or the more jumbo DC power supply of other rechargeable battery.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a structure left view of the present utility model;

Fig. 3 is a structure vertical view of the present utility model;

Fig. 4 is charging principle figure of the present utility model.

Among the figure, 1 is battery, and 2 is battery case lid, and 3 is double-point double-throw switch, and 4 are the card of wearing, and 5 are the charging output interface, and 6 is packing ring, and 7 are rotating shaft, and 8 is torsion spring, and 9 is battery case, and 10 is the battery case small circle ring, and 11 are the card small circle ring of wearing.

Battery 1 places in the battery case 9, the lower end of pendant card 4 extends a back-off, the upper end extends two card small circle rings 11 of wearing as hinge, the back side of battery case 9 is put one and is had two battery case small circle rings 10, torsion spring 8 places between two battery case small circle rings 10, two battery case small circle rings 10 place again between two small circle rings of the card 4 of wearing, the size of the small circle ring endoporus of pendant card 4 and battery case 9 and the size of rotating shaft 7 are complementary, one termination diameter of rotating shaft 7 is greater than the endoporus of annulus, the other end of rotating shaft 7 passes the card 4 of wearing simultaneously, behind the small circle ring of battery case 9 and the torsion spring 8, snap in packing ring 6 on the groove of rotating shaft 7 other ends, battery case lid 2 covers battery 1, just outer negative and interior negative outer positive output interface A in the both sides of battery case lid 2 are respectively equipped with, B and charging inlet; The top of battery cover 2 has a dpdt double-pole double-throw (DPDT) toggle switch 3, realizes two cells are selected coupled in series or parallel connection on demand; During use, firmly pinch the upper end of the top of battery case 9 and the card 4 of wearing, the side end of thread of the torsion spring 8 stressed cards of will wearing is opened, and just can be buckled at one's side.Referring to Fig. 2, according to the needs of electrical appliance, stir double-point double-throw switch 3, select two cell serial or parallel connections use in the box, and the polarity of left and right sides output interface is opposite, can satisfy the instructions for use of different electrical appliances.
