Abstract
The invention relates to a manufacturing method for a crash frame of a battery compartment for electric drive vehicles by using metallic sheets which are arranged on top of one another and fixed together and which form in a following step a space by using an inner active media forming process to create walls of a crash frame whereby the space works as a deformation space to protect the battery modules inside the battery compartment against an impact. The invention further relates to the use of the crash frame for a battery compartment.
Claims14
A method for manufacturing a crash frame for a battery compartment for electric drive vehicles, comprising the steps of
- providing at least two metallic sheets and arranging the at least two metallic sheets on top of each other
- joining the at least two metallic sheets together essentially at the circumference of at least one sheet
- introducing a medium between at least two sheets which have been joined together
- applying a pressure to the medium, causing the deformation of at least one sheet and forming a component comprising a space between at least two sheets.
