An automotive front side frame including a bent portion having a bent form, in at least a portion, comprises an outer frame including a front outer portion and a rear outer portion disposed further to a rear of a vehicle frame than the front outer portion and formed to have tensile strength higher than tensile strength of the front outer portion; and an inner frame including a front inner portion and a rear inner portion disposed further to the rear of the vehicle frame than the front inner portion and formed to have tensile strength higher than tensile strength of the front inner portion.

The present disclosure provides a vehicle lower portion structure including: a case main body portion, disposed at a vehicle lower side of a vehicle cabin floor and including a bottom wall and peripheral walls that extend toward a vehicle upper side from a peripheral edge portion of the bottom wall, and accommodating a battery at an interior thereof; a front portion extending portion formed integrally with the case main body portion at a vehicle front side of the case main body portion, at the peripheral wall that is at a vehicle front side of the case main body portion; and an impact absorbing portion, extending in a vehicle longitudinal direction and deforming due to input of collision load from a vehicle front side, a rear end portion of the impact absorbing portion being connected to a vehicle front side region of the front portion extending portion.

A vehicle body rear structure includes: left and right rear side frames extending in a fore-and-aft direction in a rear part of a vehicle; a rear subframe attached to the rear side frames; left and right rear wheels supported by the rear subframe via respective suspensions; and a driving source mounted to the rear subframe. The driving source is arranged such that a center of gravity thereof is positioned more rearward than a rotation axis of the rear wheels. The rear subframe includes left and right rear subframe longitudinal members extending in the fore-and-aft direction and a rear subframe cross member extending laterally and joined to the rear subframe longitudinal members. The rear subframe cross member includes a protrusion that protrudes rearward at a laterally central part thereof. A rear end of the protrusion is positioned more rearward than a rear end of the driving source.

A crossmember and a manufacturing method for a crossmember is disclosed. The crossmember is made of a metal sheet having a given sectional shape, configures a part of a vehicle body frame, extends along a vehicle width direction, and has an engine mount attaching portion provided in a part of an upper plate portion. The crossmember has an upper crossmember that is made of a single metal sheet extending along the vehicle width direction, the upper crossmember having a larger thickness in a region including the engine mount attaching portion of the upper plate portion and a surrounding area of the engine mount attaching portion compared to a thickness of a remaining region.

This disclosure details systems and methods for supporting and isolating vehicle body mounted battery packs from various vehicle loads. An exemplary electrified vehicle may include a frame, a battery support structure mounted to the frame, a battery pack, and one or more isolators. The battery pack is supported by the battery support structure but is not mechanically coupled to the frame. The isolator is mounted between the battery pack and the battery pack support structure for isolating the battery pack from loads that may be imparted on the frame and/or the battery support structure.

A vehicle front-end assembly includes a vehicle frame and a skid plate. The vehicle frame has a first front side member and a second front side member. Each of the first and second front side members has a corresponding front-end portion with a downward facing surface. The skid plate has a main section, a first attachment flange extending from a first lateral side of the main section and a second attachment flange extending from a second lateral side of the main section. The first attachment flange is attached to the downward facing surface of the first front side member. The second attachment flange is attached to the downward facing surface of the second front side member such that the main section covers a forward area of an underside of the vehicle.

A vehicle includes a vehicle frame elongated along a longitudinal axis. The vehicle frame includes a first rail and a second rail spaced from each other and each elongated along the longitudinal axis. The vehicle frame includes a longitudinal beam between the first and second rails and elongated along the longitudinal axis. The vehicle includes a vehicle body. The vehicle body includes a cross-beam directly connected to the longitudinal beam and to the first and second rails.

A platform structure for an electric vehicle is proposed. More particularly, according to the platform structure for an electric vehicle, a frame configured by coupling pipes to each other to form a lattice structure is installed to have a vertical double structure, and each pipe constituting an upper frame and each pipe constituting a lower frame intersect with each other such that rigidity of the platform structure is secured and the manufacturing period thereof due to easy manufacturing is decreased to reduce manufacturing cost. The platform structure for an electric vehicle includes a frame of the platform structure configured in such a manner that pipes are coupled to each other by brackets to form a lattice structure.
