A side sill for a motor vehicle has a side-sill inner part assigned to a floor assembly, a bottom flange and a side-sill outer part which bounds a cavity of the side sill, in which a reinforcing part, which is fastened to the side-sill inner part, is arranged. In order to provide a side sill which is optimized in respect of simple manufacturing and installation and also needs-oriented design, and by which improved adaptability of the components to different construction variants is possible, the side-sill inner part and the bottom flange are designed as separate components which are connected to each other at least indirectly along a flange connection running in the direction of longitudinal extent of the side sill.

Disclosed is a structural member for an automobile body includes: a hat channel member that has a top sheet portion, a pair of side wall portions extending via first corner portions, and a pair of flange portions extending via second corner portions; and a joining member that has a pair of joining portions and a top sheet facing portion, wherein a first bead extending in the longitudinal direction is formed on the top sheet facing portion, and wherein two or more second beads extending in a direction intersecting the longitudinal direction are formed on the pair of side wall portions.

A metal joined body has an iron base body and an aluminum base body that are joined together via a joint layer. The joint layer has a first layer composed of a first intermetallic compound formed on the iron base body side and a second layer composed of a second intermetallic compound formed on the aluminum base body side. The first layer has one or more first protrusions that merge integrally into the iron base body and extend in a pile shape into the first intermetallic compound. The second layer may have one or more second protrusions that are composed of a second intermetallic compound and extend in a columnar shape into the aluminum base body. The first intermetallic compound may contain Al.sub.5Fe.sub.2, and the second intermetallic compound may contain Al.sub.3Fe. The total thickness of the first layer and the second layer is, for example, 2 to 15 μm.

An electric-vehicle frame includes a mid-section and an end section. The mid-section has first and second frame rails spaced from each other by a first distance along a cross-vehicle axis defining a battery compartment therebetween. The end-section has first and second frame rails spaced from each other by a second distance along the cross-vehicle axis smaller than the first distance. A first connector is fixed to the first frame rail of the mid-section and to the first frame rail of the end-section. A second connector is fixed to the second frame rail of the mid-section and to the second frame rail of the end-section.

A side sill part (6) for an automotive vehicle comprises an outer sill member (10) and an inner sill member (12), and defining between them an outer volume (47). The side sill part also includes an external profile part (68), defining with the inner sill member (12) an inner volume (74), and a first profile part (48) extending in the outer volume (47). The first profile part comprising at least one outer contact portion (50), at least one inner contact portion (52), and at least one joining wall (54) joining the outer contact portion (50) and the inner contact portion (52). The side sill part further includes a second profile part (88) extending in the inner volume (74), comprising at least one outer contact portion (90), at least one inner contact portion (92), and at least one joining wall (94) joining the outer contact portion (90) and the inner contact portion (92).

A structural member is elongated in a longitudinal direction, and includes a first member made of a steel plate and a second member made of a steel plate, the first member and the second member being joined. In the structural member, a closed cross-sectional shape is formed by the first member and the second member in a cross section perpendicular to the longitudinal direction. The first member has a tensile strength of equal to or greater than 980 MPa, and includes a first hemming process part subjected to hemming bending at both end parts in a width direction orthogonal to the longitudinal direction. The second member has a tensile strength of equal to or greater than 980 MPa, and includes a second bonded part held in the first hemming process part at both end parts in the width direction and bonded to the first hemming process part by an adhesive.

A vehicle body structure includes: a battery disposed at a vehicle body central lower portion, i.e., at a central lower portion of the vehicle body; a side sill of a hollow shape, the side sill disposed at an outer side of the battery in a vehicle width direction and extending in a vehicle longitudinal direction; a reinforcement member disposed inside the side sill, having a closed cross section of a polygonal shape, and having a continuous cylindrical structure where a plurality of the closed cross sections are continuous when viewed in the vehicle width direction; and a deformation control member attached to the reinforcement member and configured to control a deformation of the continuous cylindrical structure of the reinforcement member in the vehicle longitudinal direction.

An automotive crashworthiness energy absorption part for being provided on a front part or a rear part of an automotive body includes: a tubular member formed using a hat-shaped section part including a top portion and a side-wall portion; a coating part configured to form a coating film arranged with a gap of 0.2 mm to 3 mm from an inner surface of the top portion, an inner surface of the side-wall portion, and an inner surface of a corner portion, on a portion including the corner portion connecting the top portion to the side-wall portion in the inner surfaces of the top portion and the side-wall portion, the coating part being made of a material having strength lower than the tubular member; and a coating film of an electrodeposition paint formed in the gap.
