Description
Technical field
The present invention relates to new energy car battery field, particularly a kind of battery bag casing with double-layer sealing structure.
Background technology
Lithium ion battery has the advantages that cost performance is high, security is good, low stain, has been achieved with more and more widely should
With, ordinary electronic field is not only applied only to, also gradually it is applied in power and energy storage field.Lithium battery is new-energy automobile
Important electrokinetic cell, as the electrokinetic cell of new-energy automobile, it is necessary to consider the use environment of new-energy automobile, such as sleet sky
Gas, freezing weather etc., a variety of environmental requirements all propose the waterproof requirement of high standard to new energy car battery.It is existing
Common batteries lodge body is generally difficult to meet the requirement, or by after long-time use, being no longer complies with the waterproof requirement.Cause
How this, improve the water resistance of existing battery bag casing, as the major issue that new-energy automobile field needs to solve.
The content of the invention
It is an object of the invention to provide a kind of battery bag body structure with high-grade water resistance, the present invention is provided
Following technical scheme：
A kind of double-layer seal battery bag casing, including casing and upper lid, the battery bag casing also include inner cap, the inner cap peace
Inner side suitable for reading loaded on the casing, the side of the inner cap is extended with extension to the side of the casing, the inner cap
The side of side, extension and casing forms U-type groove, gummed paper is provided with the U-lag, and filled in the gummed paper of the U-lag
Equipped with fluid sealant.
Used as a preferred embodiment of the present invention, the side of the casing is extended with protuberance away from side surface direction, institute
The top for being placed on the casing is stated, and is pressed in the protuberance.
As another preferred scheme of the invention, sealing ring is installed between the upper lid and the protuberance.Pass through
The sealing ring, is effectively formed sealing structure, it is to avoid the entrance of moisture or steam.
Used as another preferred scheme of the invention, the casting glue is adjacent to the side wall of the casing and the side of the inner cap
Wall.Casting glue is poured into the initial stage of U-type groove, with fairly good mobility, can be with inner cover side wall and wall box well
Laminating, to be effectively formed sealant, further avoids steam from entering into casing.
Used as another preferred scheme of the invention, the gummed paper extends to the casing by the madial wall of the casing
Protuberance.The gummed paper extends to the surface shape of protuberance, gummed paper and box inside wall, upper surface, and lateral wall and protuberance
Into good laminating, one layer of sealant is also corresponded to.
The method have the advantages that：
1st, the present invention has the upper double-layer sealing structure covered with the sealing structure of casing and the sealing structure of inner cap and casing, effectively
Moisture, steam etc. is avoided to enter into battery bag casing so that the present invention is the battery bag casing with high-grade waterproof construction；
2nd, by the present invention in that filling space with casting glue, it is ensured that the place for having space can all be filled into, so that real
Existing good sealing effectiveness；
3rd, gummed paper of the present invention extends to lateral wall from box inside wall, until protuberance, effectively improves the waterproof of battery bag casing
Performance.
