Abstract
The utility model provides a corrosion -resistant prevention of liquid leakage combined cover cap, includes the sealing washer, and the sealing washer is made by the corrosion -resisting rubber material, and sealing washer inner surface coating has a corrosion -resistant glue layer of one deck, the corrosion -resistant glue layer surface glue layer of shocking resistance that has coated again. Special rubber coating processing is carried out through the sealing washer to lithium cell combined cover cap to this scheme, coats corrosion -resistant glue and shocks resistance glue, and the sealing washer adopts corrosion -resistant material simultaneously to make the battery sealing washer reach corrosion -resistant prevention of liquid leakage's mesh.
Description
Technical field
This utility model relates to a kind of lithium battery combination cover cap, particularly to a kind of corrosion-resistant liquid-leakage preventing combination cover cap.
Background technology
Lithium battery owing to storing that energy density is big, length in service life, the advantage such as environment friendly and pollution-free, be widely used in life.The block of lithium battery combination cover cap is typically made up of carbon steel, rigidity is the biggest, when multiple cylindrical lithium batteries be in series mutually and and when being unified into set of cells, can be acted on by multiple cell stack with a block, if now by severe impact, the block that rigidity is the biggest will be transferred completely into External Force Acting on sealing ring, sealing ring can be caused its service behaviour to change by powerful active force, sealing ring sealing effectiveness is deteriorated, battery keeps this duty to arise that the problem that battery fluid is revealed for a long time, simultaneously, lithium ion in battery fluid can corrode sealing ring, finally affect the use of lithium battery, reduction of service life.
Utility model content
The purpose of this utility model is to provide a kind of corrosion-resistant liquid-leakage preventing combination cover cap, process by the sealing ring of lithium battery combination cover cap being carried out special gluing, coat corrosion-resistant glue and shock resistance glue, sealing ring uses resistant material simultaneously, so that battery seal ring reaches the purpose of corrosion-resistant liquid-leakage preventing.
Above-mentioned purpose of the present utility model has the technical scheme that a kind of corrosion-resistant liquid-leakage preventing combination cover cap, including sealing ring, sealing ring is made up of anti-corrosive rubber material, sealing ring inner surface is coated with one layer of corrosion-resistant glue layer, and corrosion-resistant glue layer surface is coated with again shock resistance glue layer.
By using technique scheme, the material selection anti-corrosive rubber material of sealing ring, sealing ring can be made to prevent by the lithium ion in electrolyte when lithium battery interior electrolyte unavoidably occurs leakage to corrode, first the corrosion-resistant glue scribbled in sealing ring carry out one layer of protection when battery fluid leaks to sealing ring, strengthen the decay resistance of sealing ring, shock resistance glue is coated on corrosion-resistant glue surface can improve the shock resistance of sealing ring, when the steel cap that rigidity is the biggest is all transferred to sealing ring foreign impacts power, shock resistance glue layer can play intermediate buffering effect, absorb impulsive force, protection sealing ring is not because being made airtight quality reduce by severe impact effect, inherently reduce the probability that battery electrolyte is revealed, extend battery.
Preferably, anti-corrosive rubber material is polypropylene.
By using technique scheme, polyacrylic chemical stability is good, in addition to being corroded by concentrated acid, all fine to the anticorrosion effect of other chemical substances, it is entirely capable of meeting the anticorrosion requirement to lithium ion, in addition, polypropylene density is little, is conducive to reducing the weight of combination cover cap.
Preferably, sealing ring is connected with steel cap, and sealing ring has the flange being wrapped in steel cap upper surface.
By using technique scheme, in other assemblies in steel cap and block can be wrapped in by the flange of sealing ring, strengthen fixation, split away off when preventing steel cap by impulsive force.
Preferably, the surface that sealing ring and steel cap are conflicted has boss structure.
By using technique scheme, on the one hand boss structure plays fixation, on the other hand the external forces passed over from steel cap can be carried out bumper and absorbing shock.
Preferably, the inner surface configuration of sealing ring flange is step-like.
By using technique scheme, the assembly that step-like flange is easy in block is installed, and has again fixed effect.
Preferably, corrosion-resistant glue is PU plastics glue.
By using technique scheme, PU plastics glue is easy to use, heat-resisting, corrosion-resistant, high with rubber bound intensity.
Preferably, shock resistance glue is epoxide resin AB glue.
By using technique scheme, epoxide resin AB glue shock resistance is good, the shortcoming that can make up sealing ring material polypropene impact-resistant difference.
To sum up, lithium battery combination cover cap is coated corrosion-resistant glue and shock resistance glue at sealing ring, so that battery seal ring reaches the effect of corrosion-resistant liquid-leakage preventing by this utility model.
Accompanying drawing explanation
Fig. 1 is corrosion-resistant liquid-leakage preventing combination cover cap sectional view.
Reference: 1, sealing ring；2, corrosion-resistant glue layer；3, shock resistance glue layer；4, steel cap；5, flange；6, boss；7, step-like.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Figure 1, a kind of corrosion-resistant liquid-leakage preventing combination cover cap, sealing ring 1 is made up of corrosion resistant polypropylene material, sealing ring 1 has flange 5 structure, sealing ring 1 inner surface is connected with steel cap 4, flange 5 is wrapped on the upper surface of steel cap 4, flange 5 inner surface is step-like 7, the surface of sealing ring 1 and steel cap 4 joint is additionally provided with boss 6, sealing ring 1 inner surface scribbles one layer of corrosion-resistant glue layer 22, select PU plastics glue, corrosion-resistant glue layer 22 scribbles one layer of shock resistance glue layer 3 again, select epoxide resin AB glue.
When steel cap 4 is by extraneous violent percussion, owing to its good rigidity can be transferred completely into impulsive force on sealing ring 1, first external force is played cushioning effect by boss 6 structure and step-like 7 structures that arrange on sealing ring 1, shock resistance glue layer 3 epoxide resin AB glue shock resistance is good, the percussion of part can be sponged, reduce external force the impact of sealing ring 1 is affected, the service behaviour preventing sealing ring 1 reduces and causes battery electrolyte to be revealed after long duration of action, makes sealing ring 1 sealing effectiveness be deteriorated；When electrolyte inevitably occurs leakage, the PU plastic cement water layer of corrosion-resistant glue layer 2 is corrosion-resistant, resists the lithium ion corrosion to rubber ring, and the sealing ring 1 that polypropylene is made also has decay resistance.Summary effect, thus can realize the purpose of the corrosion-resistant liquid-leakage preventing of battery.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
