A chassis frame for an electric vehicle may include: a first frame and a second frame spaced apart from each other in a longitudinal direction of the electric vehicle; a center frame disposed between the first frame and the second frame, and configured to have side members spaced apart from each other in a widthwise direction of the electric vehicle; a first fastener which extends from the first frame, and is fastened to a first side of the side member; and a second fastener which extends from the second frame, and is fastened to a second side of the side member, wherein the first fastener and the second fastener are configured to be in contact with entire peripheries of the side member.

A vehicle includes a frame, front and rear wheels, a powertrain comprising an engine and transmission, and various other systems and components. The frame includes various features for supporting components and systems of the vehicle. For example, a rear portion of the frame is configured to support a utility bed, a portion of a cooling system, a portion of an air intake system, and a portion of an exhaust system.

A battery housing of a motor vehicle traction battery includes at least one base plate, and two side walls which extend parallel to each other in the longitudinal direction of the motor vehicle and are spaced apart from each other in the transverse direction of the motor vehicle. Formed between the side walls is a number of receiving spaces, within each of which at least one battery module of the traction battery of the motor vehicle is accommodated. A plurality of deformation elements which are spaced apart from one another in the longitudinal direction of the motor vehicle are attached to the inner sides of the side walls. The battery modules are arranged in the receiving spaces in such a manner that, in the region of the deformation elements, lateral deformation spaces are formed between the battery modules and the side walls.

A metal extrusion and nodes based structure is provided. The structure comprises one or more arc members connected by one or more node members, wherein the arc comprises (i) a wing feature which is configured to mate with one or more non-structural components, (ii) an internal passage feature which is configured to be inserted into a connecting feature of the corresponding node member, and (iii) one or more keying features formed from a mating interface with the corresponding node member.

A joint for a motor vehicle body comprises a first structural member fabricated from aluminum attached to a second structural member fabricated from steel. The second structural member has an adjoining portion that is in substantially juxtaposed abutting relation with the first structural member when the second structural member is attached to the first structural member. The second structural member has a ramp portion terminating in a bare exposed edge on the second structural member and upon which the bare exposed edge is disposed. The bare exposed edge is displaced from the first structural member to form a gap between the first structural member and the bare exposed edge to prevent corrosion of the bare exposed edge without the use of adhesives and sealants.

A vehicle body structure having a side roof rail, a B-pillar and a bracket. The side roof rail has an inboard surface. The B-pillar has an upper end portion that overlays a portion of the inboard surface of the roof rail. The B-pillar extends downward from the roof rail. The bracket has a first portion and a second portion. The first portion is fixedly attached to the upper end portion of the B-pillar. The bracket further has a first rib and a second rib spaced apart from the first rib. The first rib and the second rib extend from the first portion of the bracket upward toward the second portion of the bracket. The first portion of the bracket further defines a slot located between the first rib and the second rib.

The present invention has as its object the provision of a T-shaped joint structure sufficiently securing a mounting region for another member and securing rigidity of a joint part. A first member and a second member joined with the first member and extending in a direction vertical to the longitudinal direction of the first member are provided. In a side view of first member in the longitudinal direction, the part of the first member joined with the second member, that is, a first member side joining element, is slanted from the first member toward the second member so that the first member becomes tapered. The part of the second member joined with the first member, that is, a second member side joining element, is slanted from the first member toward the second member in the same direction as the first member side joining element. The first member side joining element and second member side joining element are smoothly joined to form a joined part. The joined part is present at least at single side of the first and second member in the lateral direction.

A different material joining structure has: a first panel made of a first metal material; a second panel made of a second metal material that has a higher conductivity than that of the first panel, is different from the first metal material, and at least a part of which faces the first panel; and a rivet for joining the first panel and the second panel, wherein the rivet is made of the first material, and includes a head portion that is embedded in the second panel in a non-penetrating manner and a bottom portion that abuts on the first panel, and wherein a nugget portion as a joint portion is disposed between the first panel and the bottom portion, the nugget portion being formed by resistance welding the rivet to the first portion with the rivet disposed between the first panel and the second panel.

The present invention is provided with a roof side rail, a side outer panel that is formed of a dissimilar metal material having a higher electrical conductivity than the roof side rail, and a metal layer that is formed of the same metal material as the roof side rail and is disposed between the roof side rail and the side outer panel. Forming a nugget, which is a joint portion, between the roof side rail and the metal layer by carrying out resistance welding with the metal coating disposed between the roof side rail and the side outer panel makes it possible to accommodate the enhanced strength of an iron member and to render prepared hole processing unnecessary.

A front body reinforcement structure for a vehicle includes: a front side member connected to a dash panel; a front pillar which is disposed in a height direction of a vehicle body and has a lower part connected to the front side member; a front side upper member connecting a front of the front side member and an upper part of the front pillar; and a reinforcement unit that is connected with the dash panel and connects a rear of the front side member and an upper portion of the front pillar.
