  • Automobile body structure
    Patent number: 9022152
    Abstract: In an automobile body structure, since a floor panel disposed beneath left and right side sills and a battery support frame includes a center tunnel protruding upwardly and extending in the vehicle body fore-and-aft direction, and a main body portion of the battery support frame and the floor panel are connected via a linking bracket, it is possible to reinforce the battery support frame with the floor panel and prevent the battery support frame from warping into an arc shape and being bent by the collision load of a side collision and, moreover, since even if the battery support frame is formed into a straight line shape, interference with the center tunnel can be avoided, it is possible to reliably make the battery support frame buckle when the collision load of a side collision is inputted thereinto, thus enhancing the ability to absorb the energy of a collision.
