Abstract
The utility model discloses a square lithium -ion battery, including interior casing to and the outer shell body of casing including the cover, the internal insulating gum cover that is provided with of inner shell, insulating gum cover is provided with the through -hole that is used for emboliaing the lithium cell, interior casing is squarely, both ends still are equipped with the constant head tank that is used for fixed lithium cell about the interior casing, the shell body is by aluminum sheet one shot forming, the end of aluminum sheet is and is provided with a pair of through -hole, through -hole grafting fixed loop. The utility model discloses the shell body has been set up specially to fix shell body and interior casing through the fixed loop, the pressure of preventing of further having strengthened the group battery resists the striking, and the shell body is dismantled easily simultaneously.
Description
Technical field
The utility model relates to a kind of rectangular lithium ion battery group.
Background technology
Lithium ion battery and general lithium cell are all environmental protection battery, the lithium ion battery of prior art generally wraps up plastics shell, if plastics shell occurs damaged, then inner lithium electric material can overflow, in addition, plastics shell is easily damaged after being pressed, and this just further increases the application risk of lithium ion battery.
Practical novel content
(1) technical problem solved
The purpose of this utility model to be overcome above-mentioned shortcoming exactly, it is intended to provides a kind of rectangular lithium ion battery group.
(2) technical scheme
For achieving the above object, rectangular lithium ion battery group of the present utility model, comprises inner housing, and the body skin being enclosed within outside inner housing; Being provided with an insulating gum cover in described inner housing, described insulating gum cover is provided with the hole excessively for being inserted in lithium cell; Described inner housing is square, and the upper and lower two ends of described inner housing are also provided with the locating slot for fixing lithium cell; Described body skin is by aluminium sheet once shaped; The end of described aluminium sheet is and is provided with one pair of through hole, described through hole grafting set collar.
Further, described set collar quantity is 2, described set collar wear above and below through hole respectively into.
Further, described through-hole diameter 0.5-1mm.
Further, described set collar diameter is consistent with through-hole diameter.
Further, described inner housing is also provided with stiffening web.
(3) useful effect
Compared with prior art, the technical solution of the utility model has the following advantages: be specially provided with body skin, and body skin and inner housing is fixed by set collar, further enhances the impact resistance against pressure of series of cells, and body skin is easily dismantled simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of rectangular lithium ion battery group of the present utility model;
Fig. 2 is that the A-A of the utility model rectangular lithium ion battery group is to structural representation;
Fig. 3 is the structural representation of the set collar of the utility model rectangular lithium ion battery group.
Embodiment
