In the case where do similar popularization.Therefore the utility model is not limited by following public specific embodiment.
With reference to Fig. 1, the entirety of battery pack automatic fire extinguisher and the battery pack assembling of a kind of embodiment of the utility model
Schematic diagram.A kind of battery pack automatic fire extinguisher, is arranged in the upper surface of battery pack 4, including cabinet 1 and is contained in cabinet 1
The liquid-state extinguishing agent in face, 1 top of cabinet are provided with extinguishing chemical filling exit 2, and the bottom of cabinet 1 is hot melt partition 3, heat partition 3
For the liquid-state extinguishing agent of 1 the inside of cabinet to be ruptured and discharged when 4 temperature of battery pack reaches hot melt partition fusing point.
In above embodiments, on the top of battery pack 4, setting has the extinguishing device of hot melt 3 bottom of partition, when battery pack 4
Temperature reach preset temperature, the fusing rupture automatically of the hot melt partition 3 of extinguishing device bottom, extinguishing chemical outflow is by battery pack temperature
High place covering is spent, prevents the generation of fire, plays the role of the generation of fire preventing.
Further, it heats and is provided with decrease portion 31 on the surface of partition 3.
In above embodiments, hot melt 3 surface of partition is evenly arranged with decrease portion 31, and the present embodiment is specially in hot melt partition
3 inner surfaces are uniformly arranged pit, arrive the fusing point for heating partition 3 when some point temperature of battery pack 4 is relatively up to, heat on partition 3
The decrease portion preferential tear nearest from 4 temperature higher point of battery pack, liquid-state extinguishing agent outflow covers temperature higher point, such
Design is so that the position of the hot melt fusing rupture of partition 3 is more accurate.
Further, hot melt partition 3 is made of low melting point alloy.
Partition 3 is heated in above embodiments, and preferentially selection low melting point alloy is made, and has certain mechanical strength, matter
Amount is light, and fusing point is low.
Further, low melting point alloy includes Bi, Sn, Pb, In element.
In above embodiments, low melting point alloy is made of the low-melting-point metals element such as Bi, Sn, Pb, In, heat fusing
There is good mobility afterwards, according to the actual situation, fusing point required for the ratio of adjustable each element adjusts.
Further, the fusing point of partition 3 is heated between 50-70 DEG C.
Preferably, the range of low-melting alloy is set between 50-70 DEG C by the present embodiment, in actual conditions, also
