The utility model discloses a through -wall welding glues and seals battery cover, including the lid, be equipped with the resin glue groove on the terminal surface of lid, the resin glue groove includes that resin glue cross slot and resin glue erect the groove, one side of lid terminal surface is equipped with first fixed plate, second fixed plate and third fixed plate, be equipped with U type groove and first reference column on the terminal surface of first fixed plate, the terminal surface other end of third fixed plate is equipped with the second connecting plate, be equipped with the resin glue through -hole on the second connecting plate, the resin glue through -hole erects the groove with the resin glue and is connected. This through -wall welding glues and seals battery cover erects the groove through setting up resin glue through -hole, resin glue cross slot, resin glue, and the resin glue passes through the resin glue through -hole and flows in the resin glue and erect theinslot, and the resin glue passes through in the resin glue erects groove other recesses of the flow direction, and the material has not only been practiced thrift to cancellation bridge pole's position, improves the quality of product to solve among the prior art bridge pole's reserved position and put and do not change, leaded to locally with gluing the volume increase, caused battery cluster check, or even the condemned problem of battery.
