Description
Technical field
The present invention relates to a kind of cell integrated cap assembly of going up.
Background technology
Along with constantly increasing the weight of of world wide energy crisis and environmental crisis, the new forms of energy vehicle becomes more and more valued developing direction.Along with invention, development and the industrialization of this new vehicle, also be developed and performance boost as the electrokinetic cell of its key components and parts.The development degree of electrokinetic cell has limited the application of this kind new vehicle to a certain extent simultaneously.Rectangular cell structure that the appearance of electrokinetic cell has made field of batteries appearance and large-scale application, it is simple relatively that this battery structure has structure, easily become module, can form good air channel structure, safe and reliable characteristic, receive the very big concern of battery production manufacturer and car load production firm, realized the mass production of this battery.But this battery structure also has corresponding shortcoming, and wherein structural member is numerous, the cell assembling is complicated, safety valve is installed complexity, these component problems relevant with loam cake of sealing difficulty become the limiting factor that this battery is produced in batches.
Summary of the invention
The invention provides a kind of cell integrated cap assembly of going up, it not only can improve the insulation property and the sealing property of battery, and can reduce the battery cost, reduces labour intensity, has improved production efficiency.
The present invention has adopted following technical scheme: a kind of integral upper cover assembly of battery, it comprises upper cover body and safety valve, safety valve is positioned at the bottom of upper cover body, be provided with Positive Poles and negative pole pole in the upper cover body, Positive Poles and negative pole pole one end stretch out upper cover body and are positioned at outside the battery, the other end is connected with the positive and negative end of lug in the battery respectively, and lug is positioned at the top of pole piece, it is characterized in that described upper cover body, safety valve, Positive Poles and negative pole pole are for being set to integral body.
Be provided with the insulation division board between the positive and negative end of described lug, the insulation division board is positioned at the bottom of safety valve, and insulation division board and safety valve and upper cover body are integrated.Positive Poles and negative pole pole are metal, described upper cover body and safety valve are plastics, Positive Poles and negative pole pole are put into upper cover body and the safety valve mould that plastic liquid is housed, after the plastic liquid in the mould solidified, the upper cover body and the safety valve of Positive Poles and negative pole pole and injection mo(u)lding were connected to form integral body.Described insulation division board, safety valve and upper cover body are plastics, edge division board and the moulding of safety valve integral molded plastic.The bottom of described Positive Poles and negative pole pole is a unsymmetric structure, and Positive Poles is one-sided the connection with negative pole pole bottom with the positive and negative end of lug.Be distributed with boss on described Positive Poles and the negative pole pole, boss is positioned at the junction of Positive Poles and negative pole pole and upper cover body.
The present invention has following beneficial effect: upper cover body of the present invention and Positive Poles and negative pole pole are overall structure, so both can guarantee the sealing of upper cover body and pole, can guarantee pole and the loam cake insulating properties between putting forward again effectively, interior insulation cushion, inner seal ring, exterior seal ring, external insulation pad, large washer and clamp nut can have been saved simultaneously again, save design and cost of manufacture greatly, reduced battery weight.The present invention can eliminate the leakage phenomenon in the safety valve like this with upper cover body and the integrated molding structure of safety valve, and the clustered operation when having reduced the making of safety valve and upper cover body has simultaneously reduced the amount of labour, has improved production efficiency.Insulation division board of the present invention and safety valve and the integrated molding structure of upper cover body, so not only can realize effective isolation of the positive and negative end of lug, avoided lug inside, battery assembling back the short circuit phenomenon to occur, and the needed space of assurance creepage distance, realized the minimum distance design of the positive and negative end of lug, for the improvement of lug provides space basis, improved battery performance.Be distributed with boss on Positive Poles of the present invention and the negative pole pole, boss is positioned at the junction of Positive Poles and negative pole pole and upper cover body, can realize like this pole and upper cover body in injection moulding process accurately be connected reliably, guaranteed sealing property.The present invention is a unsymmetric structure with the bottom of pole Positive Poles and negative pole pole, Positive Poles is one-sided the connection with negative pole pole bottom with the positive and negative end of lug, the realization and the welding reliability of technology can have been improved so greatly, the technological operation performance can promote 50%, welding resistance can reduce by 10%, has improved the serviceability of battery greatly.
