Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further details with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, specific embodiment described in the utility model is a kind of battery safety protection device, including box body 1,
The middle part of box body 1 is provided with battery cavities 2, and battery core 3 is placed with the battery cavities 2, pressure is respectively arranged with the battery cavities 2
Force snesor 4 and temperature sensor 5, the top of box body 1 are provided with magnetic valve 6, the magnetic valve 6 and pressure sensor 4, temperature
Degree sensor 5 electrically connects, and the top of box body 1 is additionally provided with blast resistance construction 7；
The blast resistance construction includes steel cap 701, aluminium flake 702 and rupture pressure disc 703, and the rupture pressure disc 703 is located at the He of steel cap 701
Between aluminium flake 702.The bottom of box body 1 is provided with electronic lock 8, and the electronic lock 8 is L-type structure.Increase electronic lock, Ke Yiti
The security performance of high battery, it is not easy to it is stolen, while fixation is played, avoid rocking generation shock.While electronic lock is also
Blast resistance construction can be coordinated, when battery overheat or damage, when air pressure inside is excessive, when blast resistance construction loses heart, securely fix
Box body, prevent because impulsive force caused by losing heart produces secondary destruction to periphery.
In order to prevent damaging, cushion pad 9 is additionally provided between the bottom of battery cavities 2 and box body 1.Can effectively it reduce electronic
In car operation, the caused impulsive force because of jolting, the impact to battery is reduced.
In order to faster radiate, the both sides of box body 1 are provided with radiating fin 10.Radiating fin can effectively take away heat, prevent
Only battery overheats, and reduces the risk that battery explodes by overheat.
The application increases blast resistance construction and carries out duplicate protection, when battery temperature, pressure abnormity, magnetic valve master to battery cavities
Move to lose heart and avoid exploding；When cell pressure quickly raises suddenly, reversed by aluminium flake, prevent inside battery from operating, prevented simultaneously
The quick-fried passive quick pressure releasing of film, prevents from further deteriorating；Electronic lock, safe antitheft, while effective self-contained battery are provided with, reduces and shakes
It is dynamic；Cushion pad is provided with, battery will not be impacted battery because of traveling process moderately gusty air.
Described above, preferred embodiment only of the present utility model is every according to this not to limit the utility model
Any trickle amendment, equivalent substitution and the improvement that the technical spirit of utility model is made to above example, it should be included in this
Within the protection domain of utility model technical scheme.
