Abstract

Disclosed is an apparatus and method for preventing deformation of a plastic battery pack case for a vehicle, in which the side of the battery pack case is subjected to reverse deformation to absorb the deformation occurring after compression molding and to ensure the dimensions of a mounting portion of various components including battery packs, thereby ensuring an internal space of the battery pack case. To this end, the present invention provides an apparatus for preventing deformation of a plastic battery pack case for a vehicle, the apparatus including: a base having a case insertion space; a fixing portion for fixing a battery pack case inserted into the case insertion space; and a deformation producing portion inserted into the battery pack case and preventing the case from being deformed by pressing the inside of the case to be reversely deformed in the lateral direction.

Claims9

Dependent claims

A method for preventing deformation of a battery pack case for a vehicle, the apparatus comprising:

inserting the battery pack case into a case insertion space of a base so that a mounting portion of the battery pack case is received on a support and fixed by a fixing portion;
pushing an operating lever of the fixing portion up toward the inside of the battery pack case;
in response to pushing the operating lever, transferring, by an arm portion, the rotational force of the operating lever into a pressing force, wherein a pressing portion connected to the front end of the arm portion presses a top of the mounting portion of the battery pack case via the pressing force to fix the mounting portion of the battery pack case;
and
pulling down a support frame so that a pre-strain applying block and a driving portion are inserted into the battery pack case, and the pre-strain applying block is moved toward the outside of the battery pack case by the driving portion to apply pre-strain to the battery pack case and ensure that a suitable internal space in the battery pack casing is provided.
