Abstract
The utility model discloses a battery pack box body explosion prevention device. The battery pack box body explosion prevention device comprises a battery pack box body, an explosion-proof relief hole formed on the battery pack box body, and an explosion-proof valve arranged at the explosion-proof relief hole. The battery pack box body explosion prevention device provided by the utility model is simple in structure, and can eject the explosion-proof valve outside to relief pressure when the pressure reaches the set limit by adopting a check-plug-type explosion-proof valve in combination with soft rubber with proper hardness.
Description
Technical field
The utility model relates to field of batteries, particularly a kind of explosion-protection equipment that is applied to the power battery pack casing.
Background technology
Along with becoming increasingly conspicuous of environmental problem, low-carbon economy has become the main flow of economic development.So the little capacity density of volume is high, welcome by consumer and engineer.But chemical characteristic is too active, brought high danger.The lithium metal exposed in air the time, can produce fierce oxidation reaction with oxygen and explode.
Characteristics and the application scenario of current driving force battery pack itself are more special, and the user is very strict to the requirement of the aspects such as its capacity, multiplying power, reliability and fail safe.Current minitype motivation battery case body does not have explosion-proof valve, when the gas that the battery core burning produces, does not discharge in time casing, will blast.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of power battery pack box body explosion-proof device with superperformance, high efficiency, safe and reasonable.
The utility model solves the technical scheme that its technical problem adopts:
A kind of power battery pack box body explosion-proof device, comprise battery case body, is provided with the explosion-proof relief hole on described battery case body, and place, described explosion-proof relief hole is provided with explosion-proof valve.
As a preference, described explosion-proof valve comprises the non-return piece of valve rod, valve rod lower end and the fixture block of valve rod upper end.
The beneficial effects of the utility model are: 1. simple in structure, and the soft rubber of the suitable hardness of form fit of use backflow preventing mouth plug formula explosion-proof valve, when pressure reaches the setting limit, the explosion-proof valve ejection reaches the pressure release purpose; 2. explosion-proof technology is simply effective, at airtight power battery pack casing, opens relief hole, uses explosion-proof valve plug in hole, can reach the purpose of pressure-relief explosion-proof; 3. fail safe is good, and after the explosion-proof valve ejection, lethality is lower.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is stereogram of the present utility model;
Fig. 2 is the stereogram of the utility model explosion-proof valve.
Embodiment
With reference to Fig. 1.A kind of power battery pack box body explosion-proof device, comprise battery case body 1, be provided with explosion-proof relief hole 2 on described battery case body 1,2 places, described explosion-proof relief hole are provided with explosion-proof valve 3, in use as long as explosion-proof valve 3 is compressed into to explosion-proof relief hole 2, when reaching burst pressure, ejection explosion-proof valve 3 reaches battery case body 1 pressure release purpose, plays the explosion-proof protective action of battery pack.
With reference to Fig. 2.Described explosion-proof valve 3 comprises the non-return piece 32 of valve rod 31, valve rod 31 lower ends and the fixture block 33 of valve rod 31 upper ends, form backflow preventing mouth plug formula structure, wherein non-return piece 32 plays the actual blockage effect, and fixture block 33, for blocking explosion-proof valve 3, is arranged on 2 li, explosion-proof relief hole by the buckle form.Elastomeric material is used in explosion-proof valve 3 suggestions, guarantees further to alleviate lethality after its ejection.
In conjunction with top description, can find out, with respect to prior art, the utility model power battery pack box body explosion-proof scheme and device have the following advantages: simple in structure, explosion-proof technology is simply effective, fail safe is good, the scope of application is wide, is suitable for large-scale popularization on power battery pack box body explosion-proof packaging technology.
According to above-mentioned principle, the utility model can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection range of claim of the present utility model.Except using this technology, in the energy-storage battery pack module, also can use this technology in power battery pack module.In addition, although used some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
