Description
Technical field
The utility model is related to a kind of battery case, more particularly to a kind of battery bag air-leakage test structure.
Background technology
Energy shortage is increasingly serious with environmental degradation problem, and the exploitation of new energy industry is increasingly subject to the extensive pass of all circles
Note, electric car of today is main or in the majority with CNG automobile, bus, also has some motor vehicle driven by mixed powers, but its cost compared with
Height, therefore pure electric vehicle replaces existing conventional vehicle necessarily to turn into a kind of trend, it has for improving urban environment
Important meaning.In this case, the application of rechargeable battery is increasingly promoted, and battery system is used in electric car.
Electrokinetic cell bag is the core component of electric automobile, power battery of pure electric automobile group output voltage be up to 200V with
On, Battery case must seal waterproof, prevent from causing short circuit into water.Sealing directly influences the work peace of battery system
Entirely, so the requirement of Battery case degree of protection reaches IP67.
The electrokinetic cell system of IP67 degree of protection is met, it is necessary to carry out the soaked tests of IP67, to verify whether design reaches
To IP67.IP67 is a key property for concerning product safety, needs 100% ground to ensure that IP67's is effective in actual production
Property.But the soaked tests of IP67, are a tests for being possible to destroy Pack, while being also required to input ratio more time and test
Resource, it is difficult to which 100% is tested in actual production.Therefore, using air tightness test mostly now, it is substantially equivalent to
The soaked tests of IP67.
Meet the electrokinetic cell system of IP67 degree of protection, in long-term use, due to the change of the factors such as temperature, height above sea level
Change, it may appear that inside and outside pressure differential, and the pressure that seal interface can be born is certain, once external and internal pressure difference is beyond the mark
Value, seal interface will fail, and then cause IP67 protection failures.Is there is extreme case in other battery（On fire, blast）'s
When, substantial amounts of gas can be produced, if without timely pressure release, it will aggravation explosive levels.So needing on Battery case
Install explosion-proof waterproof vent valve additional.
The content of the invention
The purpose of this utility model is to provide a kind of battery easy to install and use, simple and reasonable, function-stable
Bag air-leakage test structure.
To achieve the above object, technical solution of the present utility model is：
The utility model is a kind of battery bag air-leakage test structure, including casing housing, service ports shrouding, connection spiral shell
Female, sealing ring；Service ports are offered on described casing housing, service ports shrouding is fixed on casing housing and is sealed on casing
In the service ports of housing, sealing ring is provided between casing housing and service ports shrouding, one is opened up in the middle part of service ports shrouding
Individual open-work, attaching nut be welded on service ports shrouding and with the open-work insertion of service ports shrouding.
The utility model also includes explosion-proof waterproof vent valve, and the explosion-proof waterproof vent valve is screwed onto on attaching nut.
The utility model also includes gas-tpe fitting, tracheae；Described gas-tpe fitting is fixed in tracheae outer end, gas-tpe fitting spiral shell
It is connected on attaching nut.
After such scheme, because the utility model service ports shrouding is fixed on casing housing and is sealed on casing shell
In the service ports of body, nut is welded to connect on the open-work of service ports shrouding, the attaching nut can be spirally connected with gas-tpe fitting,
It can be spirally connected with explosion-proof waterproof vent valve, a hole is dual-purpose, detection means can be pulled down after air-leakage test is complete, explosion-proof waterproof is installed
Valve is sealed, and without many perforates, without locking plug in addition, efficiently solves the sealing problem after battery bag air-leakage test and pole
The Explosion-Proof of end situation, processing with it is easy installation and reliable, reduce the production cost of battery bag, with it is simple and reasonable,
The advantage of function-stable.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is three-dimensional exploded view of the present utility model；
Fig. 2 is the schematic diagram that the utility model is equipped with gas-tpe fitting；
Fig. 3 is the schematic diagram that the utility model is equipped with explosion-proof waterproof vent valve.
Embodiment
As shown in figure 1, the utility model is a kind of battery bag air-leakage test structure, including casing housing 1, service ports envelope
Plate 2, attaching nut 3, sealing ring 4, gas-tpe fitting 5, tracheae 6, explosion-proof waterproof vent valve 7.
Service ports 11 are offered on described casing housing 1, service ports shrouding 2 is fixed on casing housing 1 and is sealed on
In the service ports 11 of casing housing 1, sealing ring 4 is provided between casing housing 1 and service ports shrouding 2, in service ports shrouding 2
Middle part opens up an open-work 21, attaching nut 3 be welded on service ports shrouding 2 and with the insertion of open-work 21 of service ports shrouding 2.
Described service ports shrouding 2 is from the thick shrouding put, and the gas impact to inflation/deflation moment has resistance well to make
With.
As shown in Fig. 2 described gas-tpe fitting 5 is fixed in the outer end of tracheae 6, gas-tpe fitting 5 is screwed onto on attaching nut 3.
As shown in figure 3, described explosion-proof waterproof vent valve 7 is screwed onto on attaching nut 3.
Application method of the present utility model：
As described in Figure 2, gas-tpe fitting 5 is screwed onto on attaching nut 3 so that gas-tpe fitting 5 is locked into hole position, gas in connection
After pipe 6, you can start air-leakage test to casing inflation.
As described in Figure 3, after gas-tpe fitting 5 is pulled down, explosion-proof waterproof vent valve 7 is locked in same hole position, you can to case
Body shell body 1 is sealed, and battery bag can be made to possess explosion prevention function.
It is described above, only the utility model preferred embodiment, therefore the utility model implementation can not be limited with this
Scope, i.e., the equivalent changes and modifications made according to present utility model application the scope of the claims and description all should still belong to this reality
