A vehicle body structure includes: a front pillar joined to a dash panel; a front side member extending from the dash panel toward the front of a vehicle; a side sill connected to a bottom end of the front pillar; a rear lower member connecting a rear portion of the front side member and a front portion of the side sill; and a connection member connecting at least two of the front pillar, the side sill, and the rear lower member. The connection member is integrally connected to the front pillar, the side sill, or the rear lower member to form a unitary one piece structure therewith.

A vehicle rocker assembly may include a sill inner comprising a sill wall portion, an upper wall portion, a lower wall portion, an upper flange portion, and a lower flange portion. The vehicle rocker assembly may also include a sill outer comprising a sill wall portion, an upper wall portion, a lower wall portion, an upper flange portion, and a lower flange portion. The vehicle rocker assembly also includes a rocker insert disposed within the elongated hollow interior, the rocker insert comprising: an upper wall, a lower wall, and a side wall extending between the upper wall and the lower wall. At least one of the upper wall or the lower wall comprises a corrugated portion that has a ridge oriented to extend in a lateral vehicle direction.

A bodywork support structure for a vehicle includes two side sills that are spaced apart in a transverse direction where the two side sills have a reinforcing element that is disposed in a hollow space. A floor is disposed between the two side sills and connected to the two side sills and an energy store for storing electrical energy and/or a fuel for powering the vehicle is disposed under the floor. The reinforcing element is formed as a corner reinforcement disposed in a corner area where the corner reinforcement has a first connection area that is attached to an external wall, a second connection area that is attached to a lower flange, and a wall area that connects the first and second connection areas with each other across the corner. An open space is formed between the corner reinforcement and an internal wall in the transverse direction of the vehicle.

A vehicle rear portion structure includes a cross member that extends in a vehicle width direction at a vehicle rear, a rear wheel house that accommodates a rear tire, a rear pillar that extends in a vehicle vertical direction, a reinforcing member that connects the rear pillar with the rear wheel house, and a joining member that connects a lower end portion of the reinforcing member with one end portion of the cross member. The rear pillar is divided into a general portion and a high-rigidity portion. The high-rigidity portion is connected to an upper end portion of the general portion and is specified with a higher rigidity than the general portion. The reinforcing member is connected to the high-rigidity portion.

On both sides under a floor of an electric vehicle, side members are provided, each in a closed cross sectional shape. Collars and the like are provided in the side members. On a lower side of a lower wall of each of the side members, cross members which are fixed by using the collars or the like are provided. Between the side members on both sides, a main battery is provided and supported by the cross members. In the vicinity of a lower side of a doorway of the electric vehicle, a cutout part is formed such that a height of a portion of an upper wall of the side member is relatively lowered. On an upper surface of the cutout part, a reinforcing member is provided. A ramp passes through a space on an upper side of the cutout part.

A side vehicle body structure ensures rigidity and shock absorption performance of the body, avoids widening of the body, and smooths the flow of exhaust gas. Embodiments include an engine, an exhaust apparatus, and a rear pillar extending upward from a rear-side portion of a side sill extending in the vehicle front-rear direction. The exhaust apparatus is disposed along the vehicle front-rear direction on the vehicle-width-direction outer side relative to the side sill. An exhaust system member is located at a going-around portion, with respect to the rear pillar, from the front side to the rear side and from the outer side to the inner side in the vehicle width direction. The rear pillar has a cross section orthogonal to the vehicle up-down direction having a shape in which a portion between front and rear ends is located on the vehicle-width-direction outer side relative to these front and rear ends.

A vehicle body reinforcement structure includes an elongated hollow structure formed by jointing an outer panel and an inner panel with each other, and a reinforcement member configured to partition the hollow structure into a lower closed cross section and an upper closed cross section. At inside of at least one of the lower closed cross section and the upper closed cross section, at least a pair of bulkheads extending so as to cross the closed cross section are disposed so as to be separated with each other in a direction in which the closed cross section is extending. A space between the pair of bulkheads is made as a filler chamber which is filled with filler. A filling opening for the filler is provided on the inner panel so that the filling opening is in communication with the filler chamber.

In an automotive structural member, weight efficiency of impact resistance is improved. An automotive structural member includes: a hollow member having plane portions; and an FRP member joined to at least one section of the plane portions, wherein: the FRP member is joined to a region of at least 0.1L1 to 0.9L1 of a length L1 in a longitudinal direction of the hollow member; the plane portion is formed with an FRP joint portion being a portion to which the FRP member is joined and an FRP non-joint portion being a portion to which the FRP member is not joined, in the region of 0.1L1 to 0.9L1; a total width of the FRP joint portion is 8 to 60% of a full width of the plane portion, in the plane portion; and a flexural rigidity of the FRP member in the FRP joint portion is 30 times or more a flexural rigidity of the plane portion excluding the FRP member in the plane portion.

An embodiment floor structure of a vehicle includes a pair of side seals disposed to face each other in a vehicle width direction, and respectively disposed in a vehicle length direction, a floor frame disposed between the pair of side seals and including a pair of longitudinal frames respectively arranged along the pair of side seals and at least one transverse frame mounted between the pair of longitudinal frames in the vehicle width direction, and at least one core structural member disposed in a space provided by the floor frame and including a material for absorbing impact.

A rocker panel molding includes an outer panel including a front integral hinge that is bendable along a first straight line extending along a vehicle length on a lower end of a front portion of the outer panel and a rear integral hinge that is bendable along a second straight line extending along the vehicle length on a lower end of a rear portion of the outer panel, a front foldable panel configured to be folded at the front integral hinge and fixed to a rocker panel, and a rear foldable panel configured to be folded at the rear integral hinge and fixed to the rocker panel.
