In view of after the integral thickness of battery container is restricted; When the operator puts into battery container with battery battery core utmost point group so; Owing to be not easy to put into, problem such as therefore cause contusions, card to hinder easily and lug is rebuffed, thus had a strong impact on the security performance of lithium ion battery.
Therefore; Press at present and develop a kind of lithium ion battery shell; It can the handled easily workman be put into battery battery core utmost point group; Thereby prevent problems such as dampening appears in battery battery core utmost point group, card is hindered and lug is rebuffed when putting into battery container, guarantee the assembly quality of lithium ion battery, improve the up-to-standard rate of lithium ion battery.
The utility model content
In view of this, the purpose of the utility model provides a kind of battery case of lithium ion battery, and it can the handled easily workman be put into battery battery core utmost point group; Thereby prevent problems such as dampening appears in battery battery core utmost point group, card is hindered and lug is rebuffed when putting into battery container; Guarantee the assembly quality of lithium ion battery, improve the up-to-standard rate of lithium ion battery, help improving the packaging efficiency of lithium ion battery simultaneously; Help using aborning widely, be of great practical significance.
For this reason, the utility model provides a kind of battery case of lithium ion battery, includes the battery case main body 20 of hollow, and said battery case main body 20 includes battery case top 21 and battery case bottom 22;
Being shaped as of said battery case main body 20 longitudinal sections is trapezoidal, and the transverse gage at said battery case top 21 is greater than the transverse gage of said battery case bottom 22.
Wherein, said battery case main body 20 is medial surface surface and all smooth housing in lateral surface surface.
Wherein, the shape of cross section of said battery case top 21 and battery case bottom 22 is rectangle.
Wherein, to exceed the size range of said battery case bottom 22 transverse gages be 0.2 ~ 0.3mm to said battery case top 21 transverse gages.
Technical scheme by above the utility model provides is visible; Compared with prior art, the utility model provides a kind of battery case of lithium ion battery, and it can the handled easily workman be put into battery battery core utmost point group; Thereby prevent problems such as dampening appears in battery battery core utmost point group, card is hindered and lug is rebuffed when putting into battery container; Guarantee the assembly quality of lithium ion battery, improve the up-to-standard rate of lithium ion battery, help improving the packaging efficiency of lithium ion battery simultaneously; Help using aborning widely, be of great practical significance.
Description of drawings
Fig. 1 is the decomposing schematic representation of the electric core package assembly of existing a kind of square lithium ion battery;
The front view of the battery case of a kind of lithium ion battery that Fig. 2 provides for the utility model;
The end view of the battery case of a kind of lithium ion battery that Fig. 3 provides for the utility model;
Among the figure: 11 is battery battery core, and 12 is the battery injecting head, and 13 is drain pan, and 14 is all-wing aircraft, and 20 is the battery case main body, and 21 is the battery case top, and 22 is the battery case bottom.
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, the utility model is done further to specify below in conjunction with accompanying drawing and execution mode.
