Portion with surrounding is smooth collectively forms cap-like structure along side.Steel cap 1 is provided with air-vent (not shown).The effect of air-vent is
After explosion-proof, the gas that battery fluid is produced is discharged from air-vent, mitigates the pressure in battery.Steel cap 1 is in normal work
When play electric action.
Explosion-proof valve 2 with smooth edge around towards provided with depressed part and constituting cap-like structure, depressed part band at battery
There is predetermined taper, its bottom surface is plane.Explosion-proof valve 2 plays conductive and sealedly effect in normal work.Steel cap 1 is along side with preventing
The quick-fried side edge of valve 2 is touched and uses laser-beam welding machine to weld its contact surface, and at least has three solder joints.Steel cap 1 is along side with preventing
Quick-fried valve 2 can also be connected using crimping mode.Explosion-proof indentation provided with annular on explosion-proof valve 2, explosion-proof indentation is groove, and its is transversal
Face is circle.In turnup structure of the edge of explosion-proof valve 2 provided with the only edge side of covering steel cap 1, turnup structure by steel cap 1 with it is close
Seal 3 is separated.Turnup structure is tubular structure, and its height is identical along the thickness on side with steel cap 1.The height of turnup structure can be low
In thickness of the steel cap 1 along side, now turnup structure only side of the part covering steel cap 1 along side, although sealing ring 3 and steel cap 1 it
Between there is space, although for the battery cap in Fig. 1, its sealing is being improved to a certain degree.The height of turnup structure
Thickness of the steel cap 1 along side can be higher than, the sealing of battery can be now better ensured that, but be due to that turnup structure is higher than steel
Part of the cap 1 along side thickness not only influences attractive in appearance, also expends more material, adds production cost, therefore optimal scheme
It is that turnup structure height is identical along the thickness on side with steel cap 1.Turnup structure is formed in one with explosion-proof valve 2.Preferably, explosion-proof valve
2 be soft flake aluminum.Turnup structure is oozed except that can be prevented effectively from the electrolyte of battery by the gap between steel cap and explosion-proof valve
Out, because sealing position only has steel cap 1 and the double layer of metal structure of explosion-proof valve 2, sealing end height, increase slot rolling shoulder height are reduced, it is real
Now widen the purpose of pole piece and hoist capacity, while consumptive material can be also reduced, it is cost-effective.
Aluminium orifice plate 5 is provided with air-vent (not shown) and the central boss towards outside batteries.The effect of air-vent is
After explosion-proof, the gas that battery fluid is produced is discharged from air-vent, mitigates the pressure in battery.The depressed part of explosion-proof valve 2
Welded with central boss using pad.Aluminium orifice plate 5 can be also connected with explosion-proof valve 2 using crimping mode.
Spacer ring 4 is provided between explosion-proof valve 2 and aluminium orifice plate 5, spacer ring 4 makes between explosion-proof valve 2 and aluminium orifice plate 5 only in pad
Place links together, and plays a part of insulation blocking.Spacer ring 4 is plastics seal.
Sealing ring 3 smears fluid sealant and by between above-mentioned part on the contact surface of explosion-proof valve 2, spacer ring 4 and aluminium orifice plate 5
Gap fill up, be allowed to bond.Wherein, sealing ring 3 is plastics seal, is wrapped up by the end of battery steel shell, the outside of sealing ring 3 with
Battery steel shell is by sealing glue bond.After on battery, sealing ring 3 plays a part of sealing and insulated.
Present invention also offers a kind of manufacture method of above-mentioned lithium ion power battery explosion protection cover, including：
S1, making steel cap：Raw material progress to making steel cap is blanking punched, is punched out processing after first one-step forming again, obtains
To the steel cap workpiece with air-vent, punching press is carried out to steel cap workpiece and forms it into the lug boss with predetermined taper, it is convex
The top surface in the portion of rising is plane, and lug boss obtains into shaped steel cap with constituting cap-like structure along side；
S2, making explosion-proof valve：Raw material progress to making explosion-proof valve is blanking punched, and carrying out punching press after first one-step forming again makes it
The explosion-proof valve workpiece of depressed part of the center with predetermined taper is formed, the wherein bottom of depressed part is plane, depressed part and side
Edge constitutes cap-like structure, and explosion-proof valve workpiece is stretched, and makes to be formed the turnup structure shaping with predetermined altitude, obtains into
Type explosion-proof valve, it is preferable that the height of turnup structure is identical with the thickness on steel shade side；
S3, making sealing ring；
S4, making spacer ring；
S5, making aluminium orifice plate：Raw material progress to making aluminium orifice plate is blanking punched, is punched out and adds again after first one-step forming
Work, obtains the shaping aluminium orifice plate with air-vent, and wherein aluminium orifice plate has central boss；
The order for making steel cap, explosion-proof valve, sealing ring, spacer ring and aluminium orifice plate is unrestricted, can be carried out according to actual conditions
Adjustment, can also be carried out simultaneously；
S6, assembling：The edge along side and explosion-proof valve of steel cap is fitted, now turnup structure only cover steel cap along side
Sidepiece, the solder joint along side and the edge of explosion-proof valve of steel cap is welded by laser-beam welding machine, wherein solder joint at least has
There are three；
After spacer ring is fitted with aluminium orifice plate, the central boss of aluminium orifice plate and the lug boss of explosion-proof valve are welded；
Sealing ring is enclosed on the outside of explosion-proof valve, spacer ring and aluminium orifice plate, and is attached by fluid sealant.
The operation principle of above-mentioned lithium ion power battery explosion protection cover is：When battery aerogenesis, air-flow is from aluminium orifice plate 5
Air-vent enters the downside of explosion-proof valve 2.As gas increases, air pressure increase, the upward stress of explosion-proof valve 2, aluminium orifice plate 5 to lower stress,
When inner and outer air pressure difference reaches breaking trigger value, the solder joint between explosion-proof valve 2 and aluminium orifice plate 5 is pulled off, and cuts off circuit, is realized disconnected
The function of road protection.After explosion-proof cap is by circuitry cuts, if still aerogenesis inside battery, air pressure increases again, when explosion-proof
When inner and outer air pressure difference reaches pressure release trigger value on valve 2, the explosion-proof indentation on explosion-proof valve 2 splits because stress is excessive, gas in battery
Air-vent of the body through explosion-proof indentation from steel cap 1 is discharged to outside battery, realizes the function of pressure release protection.
Above content is to combine specific embodiment further description made for the present invention, it is impossible to assert this hair
Bright specific implementation is confined to these explanations.For general technical staff of the technical field of the invention, do not taking off
On the premise of from present inventive concept, some simple deduction or replace can also be made, the protection of the present invention should be all considered as belonging to
