Abstract
The utility model provides a novel structure of a lithium battery case, which comprises a shell and a bottom cover. The end edge of the end face of the bottom cover is provided with a step. The width of the step is greater than the thickness of the shell. In the utility model, the end edge of the bottom cover is provided with the step, so that the bottom cover and the shell can be well welded and sealed. Moreover, the step on the bottom cover is simple to process and can be processed by stamping. Meanwhile, the structure of the battery case is suitable for various shapes of the battery cases.
Description
Technical field
The utility model relates to battery, specifically a kind of new structure of lithium battery case.
Background technology
Lithium iron phosphate dynamic battery has the advantage that many conventional batteries do not possess as a kind of novel environmental protection battery, and for example, therefore high temperature resistant, safety, long service life, electric current repid discharge etc. greatly, are applied to every field widely.
The shell of ferric phosphate lithium cell is the container of all kinds of discharging substances of splendid attire, generally adopts iron and steel material quality.See also Fig. 1, be the battery case structural representation in the known technology.One end of housing 10 need weld bottom 20 and seal, but, in the course of processing of reality, because the thickness of steel bottom 20 is less, be easy to take place buckling deformation, and cause housing 10 very difficult, and obscission also takes place in bottom 20 after the welding easily with the welded seal of bottom 20, cause the leakage of electrolyte, influence the normal use of battery.
Summary of the invention
At above the deficiencies in the prior art and defective, the purpose of this utility model is to provide a kind of new structure of lithium battery case.
The purpose of this utility model is achieved by the following technical solution:
A kind of new structure of lithium battery case comprises housing and bottom.The place, end limit of described bottom end face is provided with step, and the width of this step is greater than the thickness of described housing.
Compared with prior art, the utility model is provided with step by the place, end limit at bottom, makes bottom and housing welded seal preferably, and the processing of the step on the bottom is comparatively simple, get final product by punching press, simultaneously, this battery case structure is applicable to the battery case of different shape.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the battery case structural representation in the known technology
Fig. 2 is the overall structure schematic diagram of the new structure of a kind of lithium battery case of the utility model.
Fig. 3 is the decomposition texture schematic diagram of the new structure of a kind of lithium battery case of the utility model.
Fig. 4 is the enlarged diagram of a-quadrant among Fig. 3.
Embodiment
See also Fig. 2, Fig. 3 and Fig. 4, be respectively the enlarged diagram of a-quadrant among overall structure schematic diagram, decomposition texture schematic diagram and Fig. 3 of the new structure of a kind of lithium battery case of the utility model.This battery case comprises housing 101 and bottom 102.The place, end limit of described bottom 102 end faces is provided with step 103, and the width 104 of this step 103 is greater than the thickness of described housing 101, so that the step 103 on the bottom 102 engages with housing 101.
Adopt this kind battery case structure, the step 103 on the bottom 102 engages with housing 101, and the buckling deformation of bottom 102 can not influence the welded seal of bottom 102 and housing 101 yet, and 103 processing of the step on the bottom 102 are comparatively simple, get final product by punching press.Simultaneously, this battery case structure is applicable to the battery case of different shape, and for example, cylindrical, polygon, ellipse etc. in this embodiment, are preferred version with square battery case, are illustrated.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
