Description
[technical field]
The utility model relates to a kind of battery case.
[background technology]
Battery case is used to hold one or more batteries and the lead-in wire that is connected outside and battery.
The battery case of correlation technique comprises that casing and lid are connected to the individual layer inner cap of casing.Said casing comprise diapire, from diapire extend around the sidewall of diapire and the host cavity that is used to accommodate battery and lead-in wire that forms jointly by diapire and sidewall.
Yet the battery case of correlation technique breaks down when setting off an explosion, and the individual layer inner cap is easy to blow, and causes potential safety hazard.
In view of above drawback, be necessary to provide a kind of new battery case to overcome above-mentioned defective in fact.
[utility model content]
The purpose of the utility model is to overcome above-mentioned defective, and a kind of explosion-proof battery case is provided.
The technical problem of the utility model is to realize by following technical scheme: a kind of battery case; It comprises that casing and lid are connected to the inner cap of casing; Said casing comprise diapire, from diapire extend around some sidewalls of diapire and the host cavity that forms jointly by diapire and sidewall; Wherein, said battery case also comprises the over cap that surrounds said inner cap.
Preferably, said over cap comprises bottom and the some protection walls around the sidewall of said casing that extend from said bottom.
Preferably, the some interior walls between the protection wall of the sidewall of casing and over cap that are covered with the inwall that links to each other with the bottom of over cap in said and extend from said inwall.
Preferably, said casing also comprises the partition wall that in receiving the chamber, extends from diapire.
Preferably, said partition wall is provided with some first through holes that run through on it.
Preferably, said partition wall links to each other with said sidewall.
Preferably, said partition wall is perpendicular to diapire.
Preferably, said sidewall is provided with some second through holes that run through on it.
Compared to prior art; The utlity model has following advantage: the utility model battery case is set up over cap; When battery case breaks down when setting off an explosion, though inner cap possibly blown, as long as over cap is not blown; Air then can not get in the battery case, also can not cause the burning and the blast of battery case.

Fig. 1 is the whole stereogram of the utility model battery case;
Fig. 2 is the constitutional diagram of the utility model battery case casing and inner cap;
Fig. 3 is the stereogram of the utility model battery case casing.
[embodiment]
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described further.
To shown in Figure 3, a kind of battery case 100 is used to hold one or more batteries (not shown) and the lead-in wire (not shown) that is connected outside and battery like Fig. 1.Said battery case 100 comprises casing 1, covers the over cap 3 that is connected to the inner cap 2 of casing 1 and surrounds said inner cap 2.
Said casing 1 comprise diapire 11, from diapire 11 extend around some sidewalls 12 of diapire 11 and the host cavities 13 that form jointly by diapire 11 and sidewall 12.Said diapire 11 is square; Said two relative sidewalls 12 are parallel.
Said over cap 3 comprises bottom 31 and the some protection walls 32 around the sidewall 12 of said casing 1 that extend from said bottom 31.
The some interior walls 22 between the protection wall 32 of the sidewall 12 of casing 1 and over cap 3 that said inner cap 2 is provided with the inwall 21 that links to each other with the bottom 31 of over cap 3 and extends from said inwall 21.
Said casing 1 also comprises the partition wall (not label) that in host cavity 13, extends from diapire 11.Said partition wall links to each other with said sidewall 12 and perpendicular to diapire 11.Partition wall is divided into first host cavity 131 and second host cavity 132 with host cavity 13 like this.The setting of said partition wall can be convenient to the division of the function in the battery case, and for example battery is positioned in first host cavity; Lead placement is in second host cavity.
Said partition wall is provided with some first through holes 171 that run through on it; Said sidewall 12 is provided with some second through holes 121 that run through on it.Battery case inner ventilation and heat radiation are convenient in the setting of said through hole.
The battery case of the utility model is set up over cap, and when battery case breaks down when setting off an explosion, though inner cap possibly blown, as long as over cap is not blown, air then can not get in the battery case, also can not cause the burning and the blast of battery case.
But said over cap is provided with the casing of protection wall better protection battery case, even the sidewall of the casing of battery case is blown, the protection wall can prevent that still air from getting in the battery case.
Be covered with interior wall in said, also can prevent that air from getting in the battery case.
A kind of battery case of the utility model; Be not restricted to described in specification and the execution mode; Therefore for the personnel of familiar field, can easily realize additional advantage and modification; So under the situation of the spirit of the universal that does not deviate from claim and equivalency range and limited and scope, the examples shown that the utility model is not limited to specific details, representational equipment and illustrates here and describe.
