The layer of thermoplastic material 30 of first through hole 19, and then can rapidly reduce the temperature for the battery that generates heat,；And thermoplastic material can be made
Layer 30 preferably covers first through hole 19, improves the performance of battery case automatic extinguishing device 100.
Further, nylon, haloflex, the weight ratio of polyvinyl chloride are：Nylon：Haloflex：Polyvinyl chloride
=(90~95) %：(3~6) %：(2~4) %.When the nylon of layer of thermoplastic material 30：Haloflex：The weight of polyvinyl chloride
Fall than scope in above range, layer of thermoplastic material 30 can be allow most promptly soft when being subject to the temperature more than 120 DEG C
Change, the thermoplastic material of first through hole 19 is covered in so as to which the extinguishing chemical 90 in the first accommodating cavity 17 be facilitated to be broken through in the shorter time
Layer 30 so as to rapidly reduce the temperature for the battery that generates heat, improves the performance of battery case automatic extinguishing device 100.Specifically,
Nylon uses the nylon66 fiber in nylon material, i.e. polyhexamethylene adipamide, and the mechanical strength and hardness of polyhexamethylene adipamide are very
Height, rigidity is very big, and layer of thermoplastic material 30 can be made to cover first through hole 19 well.
It should be noted that nylon, haloflex and polyvinyl chloride in layer of thermoplastic material 30, the weight finally selected
Than accumulated result 100%.
With reference to Fig. 3, further, the thickness h of housing 10 is 1.8≤h≤2.2mm.When the thickness h of housing 10 is in above-mentioned
In the range of when, the layer of thermoplastic material 30 for being covered in first through hole 19 can be made preferably to seal first through hole 19, so as to preferably
Extinguishing chemical 90 is sealed in the first accommodating cavity 17；And when battery-heating, the extinguishing chemical 90 of vaporization can be made to rush quickly
Broken layer of thermoplastic material 30, puts out a fire rapidly, improves the performance of battery case automatic extinguishing device 100.And the thickness when housing 10
When spending h within the above range, the maximum working pressure (MWP) of the first accommodating cavity 17 can be made to be less than or equal to a megapascal, so both will not
Make extinguishing chemical 90 when being packed into the first accommodating cavity 17, the layer of thermoplastic material 30 for being covered in first through hole 19 is broken through, will not
Make battery failure adstante febre, extinguishing chemical 90 can not break through the layer of thermoplastic material 30 for being covered in first through hole 19.
In the present embodiment, further, the thickness h of housing 10 is h=2mm.It, can as thickness h=2mm of housing 10
So that the layer of thermoplastic material 30 for being covered in first through hole 19 seals first through hole 19 well, so as to preferably that extinguishing chemical 90 is close
It is enclosed in the first accommodating cavity 17；And when battery-heating, the extinguishing chemical 90 of vaporization can be made full out to break through layer of thermoplastic material
30, it puts out a fire rapidly, improves the performance of battery case automatic extinguishing device 100.
Further, housing 10 includes lateral wall 11, connection wall 15 and madial wall 13, and connection wall 15 connects 11 He of lateral wall
Madial wall 13, madial wall 13, which encloses, to be set to form the second accommodating cavity 131, and lateral wall 11, connection wall 15 and madial wall 13 are collectively formed
One accommodating cavity 17.By battery containing when the second accommodating cavity 131, battery is supported with madial wall 13 and is connected, so when battery occurs
When abnormal, battery case automatic extinguishing device 100 is facilitated to timely respond to.It is understood that the lateral wall 11, connection wall 15 and interior
Side wall 13 can be structure as a whole, and blow molding process may be employed, by layer of thermoplastic material in the form shaping easy to process of integral structure
30 are covered in first through hole 19.Certainly, lateral wall 11, connection wall 15 and madial wall 13 can also be separately set, by inside
Wall 13 is formed there through multiple first through hole 19, and layer of thermoplastic material 30 is made to cover the first through hole 19, connection wall 15 and lateral wall
11 not through such setting can make cost relatively low.It is easy to process in the present embodiment using integrally formed structure, and
It can make the better performances of battery case automatic extinguishing device 100.
With reference to Fig. 2, further, connection wall 15 is equipped with the second through hole 151, and the second through hole 151 runs through connection wall 15, battery
Case automatic fire extinguisher 100 further includes valve 70, and valve 70 is installed on second through hole 151, and controls the extinguishing chemical 90
It is filled in first accommodating cavity 17.Certainly, the position of the second through hole 151 can also be arranged on madial wall 13 or lateral wall 11
On, as long as extinguishing chemical 90 can be made preferably to be filled into the first accommodating cavity 17.Set valve 70 that extinguishing chemical 90 can be facilitated to fill out
It is filled with the first accommodating cavity 17.
With reference to Fig. 3, further, battery case automatic extinguishing device 100 further includes support plate 50, and support plate 50 is located at outside
Between wall 11 and madial wall 13.Since battery case automatic extinguishing device 100 is hollow setting, set support plate 50 that can make the
More batteries can be housed in two accommodating cavities 131 and the structure of the first accommodating cavity 17 will not be destroyed.Specifically, support plate 50
One end be held in the bottom of madial wall 13, the other end is held in the surface of 11 bottom adjacent medial side wall 13 of lateral wall.
With reference to Fig. 4, further, the aperture d of first through hole 19 is 0.2mm≤d≤0.3mm, when the hole of first through hole 19
When the numerical value of footpath d is above range, layer of thermoplastic material 30 can be made preferably to cover first through hole 19, and will not both make fire extinguishing
When being packed into the first accommodating cavity 17, the layer of thermoplastic material 30 for being covered in first through hole 19 is broken through, and will not make battery for agent 90
Failure adstante febre, extinguishing chemical 90 can not break through the layer of thermoplastic material 30 for being covered in first through hole 19.
In the present embodiment, further right, extinguishing chemical 90 is fluorination ketone extinguishing chemical.Specifically, the extinguishing chemical 90 is
