Place, the change wall section are located at below flared section, and the main paragraph, which is located at, to be become below wall section, and the wall thickness of the flared section is more than main body
The wall thickness of section, the wall thickness for becoming wall section are more than the wall thickness of main paragraph, and the internal diameter for becoming wall section is identical as the internal diameter of main paragraph,
The internal diameter of the flared section is more than the internal diameter for becoming wall section.
As a preferred embodiment of the present invention, the wall thickness of the flared section is identical as the wall thickness of wall section is become.
As a preferred embodiment of the present invention, the flared section is by the first linkage section for being obliquely installed and becomes wall section phase
Even.
As a preferred embodiment of the present invention, the wall thickness of first linkage section is identical as the wall thickness of flared section.
As a preferred embodiment of the present invention, the change wall section is connected by the second linkage section with main paragraph, and described
The internal diameter of two linkage sections is identical as the internal diameter of main paragraph.
As a preferred embodiment of the present invention, the outer diameter of second linkage section is sequentially increased from the bottom to top.
As a preferred embodiment of the present invention, the bottom surface, the first linkage section, becomes wall section, the second connection at flared section
Section, main paragraph are structure as a whole.
As a preferred embodiment of the present invention, the top surface of the flared section is provided with the approaching face of arcuate structure.
Beneficial effects of the present invention are, a kind of flaring battery case becoming wall thickness have it is simple in structure, easily manufactured, enter
Core is convenient, is convenient for slot rolling, is convenient for the characteristics of edge sealing.

Specific implementation mode
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.It is appreciated that
It is that embodiment described herein is used only for explaining the present invention rather than limitation of the invention.
It please refers to shown in Fig. 1 to Fig. 3, Fig. 1 is a kind of structural schematic diagram for the flaring battery case becoming wall thickness；Fig. 2 is Fig. 1 institutes
A kind of enlarged drawing of the flaring battery case of the change wall thickness shown at A；Fig. 3 is a kind of flaring battery case becoming wall thickness shown in FIG. 1
Enlarged drawing at B.
In this present embodiment, a kind of flaring battery case becoming wall thickness, including shell, the top of the shell are provided with out
Mouthful, the shell includes bottom surface 1 and the side wall being set on bottom surface 12, and the side wall 2 includes flared section 21, becomes wall section 22, is main
Body section 25, the flared section 21 is located at opening, and the top surface of flared section 21 is provided with the approaching face 24 of arcuate structure, the change
Wall section 22 is located at 21 lower section of flared section, and the main paragraph 25, which is located at, becomes 22 lower section of wall section, and the wall thickness of the flared section 21 is more than master
The wall thickness of body section 25, the wall thickness for becoming wall section 22 are more than the wall thickness of main paragraph 25, wall thickness and the change wall section of the flared section 21
22 wall thickness is identical, and the internal diameter for becoming wall section 22 is identical as the internal diameter of main paragraph 25, and the internal diameter of the flared section 21, which is more than, to be become
