Abstract

Provided is a battery case cover which can be produced through a single process, by integrally forming the structural components of a battery case cover such as a recovering part, a cell partition part and a gas inlet part on the bottom surface, while forming the recovering part in the shape of a pipe and applying a vent cap mode to the gas inlet part.

Claims (13)

1. A battery case cover which uses an electrolyte, comprising:

a cell partition part formed on the bottom surface of the case cover as a part thereof in a way of corresponding to the cell partitions of the battery case;

a recovering part in the shape of a pipe which is integrally formed with the case cover and the cell partition part, passing from one side of a bottom surface of the case cover, through the cell partition part, to the other side; and a gas inlet part, at least one of which is provided in each cell defined by the cell partition part, in a way of being integrally formed with the recovering part, so that a gas generated in the battery is flown into the gas inlet part,

wherein the recovering part comprises a recovering hole in an area where the gas inlet part is not placed.

2. The battery case cover according to claim 1 , wherein the recovering part comprises an explosion proof filter part on each end thereof.

3. The battery case cover according to claim 2 , wherein the explosion proof filter part further comprises: a filter housing which is coupled to each end of the recovering part;

and an explosion proof filter placed in the filter housing.

4. The battery case cover according to claim 1 , wherein a handle receiving part which can keep the handle, is formed on the top surface of the cover.

5. The battery case cover according to claim 1 , wherein the gas inlet part is formed integrally with the recovering part, such that the lower part of the gas inlet part faces down, forming the shape of a T.

6. The battery case cover according to claim 5 , wherein the inner structure of the gas inlet part is a labyrinthine structure.

7. The battery case cover according to claim 6 , wherein the bottom surface of the gas inlet part is closed and at least a hole is provided on one side of the gas inlet part.

8. The battery case cover according to claim 5 , wherein the bottom surface of the gas inlet part is closed and at least a hole is provided on one side of the gas inlet part.

9. The battery case cover according to claim 8 , wherein the bottom surface of the gas inlet part is formed in a vent-cap mode in which the structure of the bottom surface is open at the time of production, and later closed by a certain pressure after the production.
