Flat frame module for use in chassis of electric vehicle, has bars formed by profiles with L-section defining laterally juxtaposed casings for forming horizontal limb of L-section, where casings are designed with different wall thickness

摘要

The module (30) has two bars (10) laterally supported below a battery tray and formed by extruded profiles made from aluminum. The bars are connected with one another by cross-pieces (31-36). A vat is provided for batteries and placed below the bars for supporting the batteries. Each profile has an L-section defining laterally juxtaposed casings (11, 12, 13) for forming a horizontal limb of the L-section, where the casings are directed towards outside. The casings are designed with different wall thickness. Nuts are longitudinally threaded in a lower box (14).
