Abstract
It the utility model is related to battery case field, and in particular to a kind of battery steel shell structure.Including drain pan and side wall, side wall and drain pan surround the cavity of one end open, and side wall upper part outer rim sets fluted, and sidewall upper has been uniformly arranged multiple V-notch.The utility model, it is simple in construction, by groove is set and V-notch be effectively prevented in encapsulation process side wall bending part due to during bending flow of metal it is serious, be easily broken, reduce defective products rate.
Description
Technical field
It the utility model is related to battery case field, and in particular to a kind of battery steel shell structure.
Background technology
In the battery steel shell used at present, the side wall of the box hat of battery generally by bottom wall and positioned at bottom wall upper end is formed, but
Be its in encapsulation process side wall bending part due to during bending flow of metal it is serious, be easily broken, increase it is bad
Product rate, increase the Productive statistics of enterprise.
Utility model content
Technical problem to be solved in the utility model is what a kind of anti-box hat was broken in capping processes caused by bending
Battery steel shell structure.
To achieve these goals, technical scheme provided by the utility model is：
A kind of battery steel shell structure, including drain pan and side wall, side wall and drain pan surround the cavity of one end open, side wall upper part
Outer rim setting is fluted, and sidewall upper has been uniformly arranged multiple V-notch.
Specifically, the inner surface and outer surface of the side wall and drain pan are uniformly electroplate with one layer of nickel dam.
Specifically, the depth of the groove is 1 millimeter.
Specifically, the height of material of the position height of the groove with being contained in cavity is identical.
Compared with prior art, the beneficial effects of the utility model are：
The utility model, it is simple in construction, by groove is set and V-notch to be effectively prevented side wall in encapsulation process curved
Folding partially due to bending during flow of metal it is serious, be easily broken, reduce defective products rate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Parts title in accompanying drawing is：
1st, side wall, 2, drain pan, 3, groove, 4, V-notch, 5, cavity.
Embodiment
As shown in figure 1, a kind of battery steel shell structure, including drain pan 2 and side wall 1, side wall 1 and drain pan 2 surround one end open
Cavity 5, the top outer rim of side wall 1 sets fluted 3, and the upper end of side wall 1 has been uniformly arranged multiple V-notch 4.
The side wall 1 and the inner surface of drain pan 2 and outer surface are uniformly electroplate with one layer of nickel dam.
The depth of the groove 3 is 1 millimeter.
The height of material of the position height of the groove 3 with being contained in cavity 5 is identical.
In encapsulation, due to setting the position height and the height phase of the material contained in cavity 5 of fluted 3 and groove 3
Together, the material in cavity 5 can be compressed when therefore the side wall 1 on the top of groove 3 is bent to the center line of cavity 5, groove 3 can be to prevent
Only ftractureed outside side wall 1 in deformation process because deformation is serious, while can also prevent that the top of side wall 1 is curved into cavity 5
Bending place during folding is highly different, and V-notch 4 produces pleat when can prevent the upper end of side wall 1 from being bent to the centerline direction of cavity 5
Wrinkle, causes poorly sealed, leaks.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
