Specific embodiment
Below with reference to specific attached drawing, the invention will be further described:
Such as Fig. 1: a kind of protective case for preventing lithium ion battery pole from corroding, it is characterised in that: protective case ontology 1, the guarantor
Internal protective cover 2 and outer jointing jacket 3 are provided on sheath ontology 1,2 upper end of internal protective cover is provided with air circulation portion 4,
4 upper end of air circulation portion is provided with hollow portion 5, in the internal protective cover 2 and the air circulation portion 4 and institute
The first venthole 6 and the second venthole 7 are respectively arranged between the air circulation portion 4 stated and the hollow portion 5；
Wherein, 1 inside end of protective case ontology is provided with thread groove；
The internal protective cover 2 extends to inner wall from the 3 bottom external end of outer jointing jacket, and with the outer jointing jacket 3
Between soft rubber material is set as by viscose glue connection and the material of the internal protective cover 2, the outer jointing jacket 3
Material is set as hard plastics；
Between the air circulation portion 4 and the internal protective cover 2 and the outer jointing jacket 3 contact surface be provided with it is thermally conductive
Medium and the air circulation portion 4 and 3 outer surface of outer jointing jacket are provided with thermal dispersant coatings；
5 structure setting of hollow portion is that the material for the type shape structure and hollow portion 5 flated while justifying is set as
Flexible material；
Second venthole, 7 inside end is provided with return-air valve.
In the present invention, internal protective cover 2 is connected to air circulation portion 4 and is connected to hollow portion 5, and it is logical to be equipped with first between any two
Stomata 6 and the second venthole 7, the material of outer jointing jacket 3 are hard plastics, and the material of internal protective cover 2 is soft rubber material
Material, extends to inner wall by 3 bottom external end of outer jointing jacket, and the rubber material thickness of inner wall is thinner than the rubber material of bottom, in
There is thread groove, be connected with pole, has preferably air-tightness, while air circulation portion 4 and hollow portion 5 are mainly used for the circulation of air
And evacuation, and air circulation portion 4 and hollow portion 5 can also reduce the temperature of pole, have certain thermal conductivity and thermal diffusivity,
