Li-ion batteries piles
Technical field
The utility model relates to a kind of Li-ion batteries piles.
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 Li-ion batteries piles.
(2) technical scheme
For achieving the above object, Li-ion batteries piles of the present utility model, comprises inner housing, and the body skin being enclosed within outside inner housing; Some lithium celies it are arranged with in described inner housing; Described inner housing both sides are curved, are provided with strongback between described inner housing both sides and described lithium cell; Described body skin is made up of the first aluminium part and the 2nd aluminium part; The end of described first aluminium part and described 2nd aluminium part is hook-shaped, and is mutually engaged.
Further, between each lithium cell described, insulation layer is set.
Further, described strongback is fixedly connected with above-mentioned lithium cell by bandage.
Further, described inner housing is provided with stiffening web.
Further, being also provided with safety valve, described safety valve is through inner housing and body skin.
(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 be engaged by the hook-shaped of body skin, further enhance the impact resistance against pressure of series of cells, also it is provided with safety valve, when there is battery drain, safety valve can be ejected because of external and internal pressure difference, prevents blast.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail. Following examples are for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, Li-ion batteries piles of the present utility model, comprises inner housing 1, and the body skin 2 being enclosed within outside inner housing 1; Some lithium celies 3 it are arranged with in described inner housing 1; Described inner housing 1 both sides are curved, are provided with strongback 4 between described inner housing 1 both sides and described lithium cell 3; As shown in Figure 2, described body skin 2 is made up of the first aluminium part 5 and the 2nd aluminium part 6; As shown in Figure 3, the end of described first aluminium part 5 and described 2nd aluminium part 6 is hook-shaped, and is mutually engaged.
Between each lithium cell 3 described, insulation layer 7 is set, prevents from occurring between battery short circuit.
Described strongback 4 is fixedly connected with above-mentioned lithium cell 3 by bandage 10.
Described inner housing 1 is provided with stiffening web 8, reinforces inner housing 1.
Also being provided with safety valve 9, described safety valve 9 is through inner housing 1 and body skin 2, and when leakage situation occurs in lithium ion battery, safety valve 9 can be ejected because of external and internal pressure difference, prevents battery explosion.
Li-ion batteries piles of the present utility model, is specially provided with body skin, and is engaged by the hook-shaped of body skin, further enhance the impact resistance against pressure of series of cells, also it is provided with safety valve, when battery drain occurs, safety valve can be ejected because of external and internal pressure difference, prevents blast.
In sum, above-mentioned enforcement mode is not restricted enforcement mode of the present utility model, the modification that the technician of all this areas carries out on the basis of flesh and blood of the present utility model or equivalent deformation, all at technology category of the present utility model.
