Abstract:
A side sill reinforcement structure for an electric vehicle includes a battery unit 10 for driving that is disposed at a lower portion of a vehicle cabin R of an electrical vehicle 1, a side sill 20 that extends in a vehicle front-rear direction on an outer side of the battery unit 10 in a vehicle width direction, and a reinforcing member 40 that connects the battery unit 10 and the side sill 20. The reinforcing member 40 is an extruded member made of an aluminum alloy, and has a closed cross-section portion group 40A in which a plurality of closed cross-section portions is arrayed in a row in the vehicle width direction, on a cross-section perpendicular to the vehicle front-rear direction. The closed cross-section portion group 40A includes a first closed cross-section portion 41 disposed on an innermost side in the vehicle width direction, and a second closed cross-section portion 42 disposed adjacent to the first closed cross-section portion 41. The first closed cross-section portion 41 includes a first upper wall 41a and a first lower wall 41b that extend in the vehicle width direction, and that are disposed away from each other and face each other in a vehicle up-down direction. The second closed cross-section portion 42 includes a second upper wall 42a and a second lower wall 42b that extend in the vehicle width direction, and that are disposed away from each other and face each other in the vehicle up-down direction. The thickness of the first upper wall 41a is greater than the thickness of the second upper wall 42a, and the thickness of the first lower wall 41b is greater than the thickness of the second lower wall.
