Background technology
Used as a kind of new clean energy resource, because lithium-ion-power cell has, energy density is big, safety is good, weight Gently, the advantages of having extended cycle life, has been widely used in the energy-storage system in new-energy automobile.Especially in electric automobile energy storage Field, lithium-ion-power cell has become first-selected battery variety.
Lug, is a kind of conductor of lithium ion polymer battery product.Battery is a point both positive and negative polarity, and lug is exactly from battery core The middle metallic conductor for extracting both positive and negative polarity, the popular ear for saying battery positive and negative polarities is the contact when discharge and recharge is carried out Point.Lug is divided into three kinds of materials, and the positive pole of battery uses aluminum, negative pole to use nickel material, negative pole also to have copper to plate nickel material, it Be all to be composited by film and metal tape two parts.
Existing Soft Roll power battery module design is punched first at cell polar ear, is being gone here and there or several several with high temperature gummed tape And battery core is intertwined, then with support on inserts conflux piece fastened by screw assembling, two sides paste EVA foams, then With heat-shrinkable T bush entirety pyrocondensation.Due to needing to be punched at cell polar ear, by heavy damage cell polar ear overcurrent capability and increasing The internal resistance of big lug, causes battery core to descend temperature to raise in working order, and lug and the piece that confluxes are fastened in internal stent by screw, Also with respect to operating difficultiess and fragile cell polar ear;The outside radiating that battery core is had a strong impact on using heat-shrinkable T bush cladding;Therefore, its Structure has a strong impact on safety of the lithium-ion-power cell in new-energy automobile application, and production and assembly are difficult.
Therefore, the fixed structure of Soft Roll electrokinetic cell lug is further improved.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of Soft Roll electrokinetic cell lug Novel fixing structure.
In order to realize above-mentioned purpose, the technical solution of the utility model is:
A kind of fixed structure of Soft Roll electrokinetic cell lug, including plastic rubber bracket, lug pad, lug cover plate and battery core, Battery core loads in plastic rubber bracket, and through the lug hole in plastic rubber bracket lug groove, the lug of the battery core is folded the lug of battery core After be laid on lug pad, lug cover plate is covered on lug, and lug cover plate and lug pad are screwed in plastic cement In the lug groove of frame, conduction connecting structure is formed by laser welding between lug cover plate, lug and lug pad.
Further, positive pole nickel sheet is stamped on the positive pole ear after folding, lug cover plate, positive pole nickel sheet and lug pad pass through Screw is fixed in the lug groove of plastic rubber bracket, and laser welding is passed through between lug cover plate, positive pole nickel sheet, lug and lug pad Form conduction connecting structure.
Further, in conduction connecting structure, lug cover plate forms laser beam perforation, wears without laser on lug and lug pad Hole.
Further, in conduction connecting structure, positive pole nickel sheet forms laser beam perforation.
This utility model is better than traditional screw fixation contact using laser welding, does not result in showing for loose contact As;Meanwhile, it is not used in being punched on cell polar ear, the lug of battery core do not destroyed, it is ensured that electric current is stablized;Enhance Safety of the lithium-ion-power cell in new-energy automobile application.
