Compared with prior art, the utility model is improved on the basis of existing battery cell case, and improvement is to add
Structure at fluid apertures.In battery field, when battery works normally, the indoor air pressure of single battery should be less than 15,000
Pa, and when air pressure is between 15-25 kPas be unusual condition, can reduce accumulator property, but and be not fatal, after battery is cooling
Still it can be used, and the air pressure of single battery room is more than the irreversible damage of battery generation after 25 kPas, is needed replacing.This reality
With Novel assembling at battery be that liquid feeding is carried out by stepped hole, stepped hole is all had on each single battery room, when some
When the air pressure of single battery room is excessively high (air pressure is more than 15 kPas), stick harness is moved up, and single battery room passes through stepped hole and exhaust
Hole is connected to groove, and high pressure gas enters in groove, pressure reduction, and high pressure gas is contacted with heat sink reduces temperature, heat dissipation
Cooling fin on plate is quickly cooled down high pressure gas, to reduce the pressure of high pressure gas again, avoids the deformation of battery and quick-fried
It is fried.Ventilated membrane guarantees that electrolyte will not pass through gas vent with high pressure gas and overflow single battery room, i.e. guarantee electrolyte will not be outer
It lets out.When single battery room pressure increases too fast, air pressure and air pressure can not be effectively reduced by the heat dissipation of heat sink and increased
When more than 25 kPas, rupture disk work, high pressure gas is discharged from blast hole, it is further guarantee battery will not deform with it is quick-fried
It is fried, meanwhile, fragmentation after rupture disk work can give user's warning function, user is reminded to carry out battery replacement.Therefore, this reality
Have the advantages that electrolyte will not leak, battery will not deform and battery will not explode for battery with novel.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.A kind of battery cell case with floating stick harness, as shown in Figure 1, include rectangular shell 1, shell 1 with
Existing battery cell case is identical, has on cover board for plastic material including open-topped cabinet and the cover board for being top of the box
There is positive and negative anodes connecting terminal, fixed between cabinet and cover board using gluing or ultrasonic bonding,
The top of shell 1, i.e. cover board are equipped with groove 2, and the top of groove 2 is equipped with heat sink 3, and heat sink 3 is by 2 envelope of groove
Cavity is closed into, multiple single battery rooms 4 side by side are equipped in shell 1, are equipped with partition 5, Mei Gedan between neighboring unit cell room 4
The top of body battery chamber 4 is equipped with the stud 6 in groove 2, is equipped with up big and down small stepped hole 7, stepped hole 7 in stud 6
It being connected to corresponding single battery room 4, stick harness 8 is equipped in the macropore of stepped hole 7, stick harness 8 is connect by spring 9 with nut 10,
Nut 10 and the top of stud 6 are fixed, and the side wall of stud 6 is equipped with the gas vent 11 being connected to groove 2, the diameter of gas vent 11
3-5mm, gas vent 11 are connect with the side wall of stick harness 8.The nut 10 is cap nut.
The edge at 2 top of groove is equipped with step, and the periphery of the heat sink 3 is equipped with the scrap (bridge) 12 agreed with step,
Scrap (bridge) 12 is fixed by screw 13 and 1 phase of shell.
The side wall of the heat sink 3 is equipped with first annular slot, is equipped with the first sealing ring 15 in first annular slot.
It is equipped with through slot 16 on the top and bottom of the heat sink 3, is equipped with multiple cooling fins 17 in through slot 16.
The heat sink 3 is equipped with explosionproof hole, is equipped with rupture disk 18 in blast hole.The rupture disk 18 uses Shanghai Hua Li
The antiarch of safely assembled Co., Ltd production falls off type rupture disk YT, and explosion occurs when pressure is greater than at 25 kPas.
The side wall of the stick harness 8 is equipped with the second annular groove, is equipped with the second sealing ring 20 in the second annular groove.
