Abstract:
1. An automobile body structure in which a battery support frame extending in a vehicle width direction provides a connection between left and right side sills extending in a vehicle body fore-and-aft direction, and a battery disposed between the left and right side sills is supported on the battery support frame, wherein the battery support frame comprises a high strength steel sheet main body portion, a floor panel disposed beneath the left and right side sills and the battery support frame comprises a center tunnel protruding upwardly and extending in the vehicle body fore-and-aft direction, and the main body portion and the floor panel are connected via a linking bracket, the battery support frame comprises left and right weak portions connectedly provided on outer sides, in the vehicle width direction, of the main body portion and connected to the left and right side sills, and the left and right weak portions are formed from a general steel sheet that is weaker than the main body portion, and the main body portion is formed by welding first and second members such that the two sheets are superimposed so as to give a hollow closed cross-section, the weak portion is formed by welding third and fourth members such that the two sheets are superimposed so as to give a hollow closed cross-section, and a section where the main body portion and the weak portion are joined is welded such that the positions at an outer end in the vehicle width direction of the first and second members and the positions at an inner end in the vehicle width direction of the third and fourth members are displaced from each other in the vehicle width direction to thus make the number of superimposed sheets no greater than three sheets.
