Abstract
A maintenance-free storage battery cover favorable for balancing the internal gas pressure of a unit cell is used for solving the problem of nonuniform gas exhaust, and comprises a big cover and an exhaust cover. The binding surface of the big cover and the exhaust cover is heat sealed; an exhaust port is formed on the exhaust cover; and a labyrinth channel for the backflow of the escaped air which leads to the exhaust port is formed in each unit cell. The structure after improvement is as follows: one exhaust port is formed, and located at the middle part of the exhaust cover far from a terminal side; the labyrinth channels for the backflow of the escaped air are symmetrically arranged on the sides of the exhaust port; and the differences among the stroke lengths of the labyrinth channels for the backflow of the escaped air are less than 20%. The design adopted by the utility model enables the length of the gas traveling from an air escape hole on each unit cell to a general exhaust hole of the storage battery to be the same, thereby ensuring the internal gas pressure of each unit cell is basically the same, and avoiding or reducing local plastic deformation of the storage battery shell. Moreover, one side backflow port is formed at a die cavity part of a gas-filtering plate of the big cover of the storage battery, so that the acid spraying caused by the liquid accumulation at the die cavity part of the gas-filtering part is avoided.
