Specific embodiment

Below in conjunction with the attached drawing in the utility model embodiment, to the technical solution in the utility model embodiment It is clearly and completely described.

As shown in Figures 1 to 3, battery device described in the utility model embodiment, including, shell 1 is set on the shell 1 There are anode 21 and cathode 22, the shape of the shell 1 consistent with the 3*AA battery pack form fit that needs are replaced；And lithium battery 3, the lithium battery 3 is placed in the shell 1, and the lithium battery 3 is electrically connected with described positive 21 and the cathode 22, the lithium The output voltage of battery 3 is matched with the output voltage of the 3*AA battery pack.

Show the 3*AA battery pack form fit one that the utility model is replaced by the shape and needs that make shell 1 It causes, if shape is identical, length, width and height size is identical and the positive position being arranged with cathode is identical, so that battery device energy Enough be directly mounted at electronic product be originally intended to installation 3*AA battery pack position, and again due to the output voltage of lithium battery 3 with The output voltage of 3*AA battery pack matches, thus lithium battery 3 can directly for need the electronic product using 3*AA battery pack into It exercises and uses, to thoroughly solve the problems, such as that existing part electronic product is not available lithium battery substitution 3*AA battery pack.

It may be noted that AA battery has defined dimensional standard, 3*AA battery pack is then by three AA battery side-by-side series groups It fills, so 3*AA battery pack also will be provided with corresponding size specification, as long as being set as the shell 1 of battery device to meet this Specification, and the 3*AA battery pack output voltage having the same for guaranteeing lithium battery 3 and needing to substitute, just can pass through the utility model Substitution of the battery device to 3*AA battery pack.

Wherein, the shape of shell 1 can be varied, and it includes two opposite that a kind of preferred mode, which can be the shell 1, The panel 11, two of arrangement end plate 12 positioned opposite and two side plates 13 positioned opposite, the end plate 12 and the side plate 13 It is placed between two panels 11, and two end plates 12 are placed between two side plates 13, described positive 21 and described negative Pole 22 is respectively arranged on two end plates 12, i.e., shell 1 surrounds a confined space by panel 11, end plate 12 and side plate 13, with This storage lithium battery 3 and other related devices；It should also be noted that part 3*AA battery pack position corresponding with panel 11 is flat Face, it is tabular that the panel 11 can be arranged at this time, and the 3*AA battery pack shape of battery device and this type is made with this Match；Also there is part 3*AA battery pack position corresponding with panel 11 that three cambered surfaces being arranged side by side are set, can make at this time every The outer surface of panel 11 described in block is all provided with there are three the arc surface being arranged side by side, and the both ends of each arc surface each extend over It is extremely concordant with two end plates, to ensure the 3*AA battery pack form fit of battery device and this type.

In addition, the length of general 3*AA battery pack is 48mm, width 42.4mm, with a thickness of 13.45mm, so in order to protect The size of shell 1 and the form fit of 3*AA battery pack are demonstrate,proved, a kind of preferred mode can be two 11 outer surfaces of panel Maximum spacing is 12mm~14mm, and the maximum spacing of two 12 outer surfaces of end plate is 47mm~49mm, outside two side plates 13 The maximum spacing on surface is 41mm~43mm, and the maximum spacing that more can be two 11 outer surfaces of panel is 13.45mm, two institutes The maximum spacing for stating 12 outer surface of end plate is 42.4mm, and the maximum spacing of two 13 outer surfaces of side plate is 48mm；Shell 1 at this time Dimensions it is identical as the dimensions of general 3*AA battery pack, so that it is guaranteed that battery device can be suitable for most of need Use the electronic product of 3*AA battery pack.

Furthermore to reinforce the using flexible of lithium battery 3, charge function, a kind of preferred mode can be increased for lithium battery 3 It can be to appear on the shell 1 and have charging interface 4, the charging interface 4 is electrically connected with the lithium battery 3；It at this time will charging It connects 4 mouthfuls to be electrically connected with corresponding power supply source, can charge for lithium battery 3, to ensure the reusable of battery device；And In order to improve the convenience of charging, it is preferable to use micro USB interface is as charging interface 4, this will be convenient for user using now Some phone charger etc. charge.

Further, in order to avoid charging process damages lithium battery 3, can also increase for battery device corresponding Structure is protected, it further includes charge protector plate 5 that a kind of preferred mode, which can be the battery device, the charging interface 4 It is electrically connected with the charge protector plate 5, the charging interface 4 passes through the charge protector plate 5 and the lithium battery 3 Electrical connection；Charge protector plate 5 can limit charging current at this time, avoid overcharging lithium battery 3, to mention The high service life and safety of lithium battery 3；And the charging situation that lithium battery 3 is understood for the ease of user, can also be such as Indicator light 7 is added shown in Fig. 1, when indicator light 7 lights green light, shows that lithium battery 3 fills with, when indicator light 7 flashes the redlight When, then showing lithium battery 3 also needs to continue to charge.

Finally, in order to enable contact of the battery device with electronic product is good, can using anode 21 and electronic product into Row elasticity abuts, and a kind of preferred mode can be the charge protector plate 5 and described positive 21 positioned opposite, described to fill Electric protection circuit board 5 is connected with elastic component 6, and the elastic component 6 is also connect with described positive 21, and the elastic component 6 is for pushing Described positive 21 carry out elastic abutting；Battery device is installed in electronic product at this time, elastic component 6 will push anode 21 to shift to The related electrode of electronic product abuts state to ensure that anode 21 is in close with the related electrode of electronic product.

Certainly, elastic component 6 can be rubber parts or spring etc., when for example elastic component is rubber parts, when anode 21 is by outer Power squeezes, and rubber parts, which will be pressurized, to be shunk, and applies elastic force to anode 21, is abutted with guaranteeing that anode 21 is in elasticity with force application part State, it should be pointed out that, at this time in order to guarantee that anode 21 and 5 moment of charge protector plate are in status of electrically connecting, it can be used one Length is slightly longer than anode 21 and the conducting wire of 5 maximum distance of charge protector plate is attached.

And when elastic component 6 is metal spring, the working principle and rubber parts of metal spring are almost the same, but due to metal Spring itself can be realized anode 21 and electrically conduct with charge protector plate 5, so no setting is required, conducting wire is attached, i.e., Mode better than selects rubber parts as elastic component at this time.

The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit Decorations are also considered as the protection scope of the utility model.
