A vehicle body structure for safely protecting a high-voltage, the vehicle body structure including: a battery mounted on bottom portions of a center floor and a rear floor; and a protective structure having a bottom portion on which a peripheral portion of the battery is mounted and including panels fitted to each other into a shape covering a peripheral portion of the center floor.

A front vehicle-body structure for appropriately dispersing a collision load includes a floor panel; a side sill; a floor frame extending in a front-rear direction on a vehicle-width-direction inner side of the side sill; and a first cross member connecting the side sill and the floor frame to each other in the vehicle width direction. The side sill has a raised wall and an upper wall portion positioned on the vehicle-width-direction inner side in a cross-section orthogonally intersecting with the front-rear direction and extending in an up-down direction, a corner extending in the front-rear direction is formed between the raised wall and the upper wall portion, and a first joint member and a corner reinforcement member that reinforce the raised wall and the corner are provided at a position to which the first cross member is connected in the front-rear direction on an inner side of the side sill.

An embodiment vehicle impact energy absorption system includes a dash panel, a pair of front side members extending toward a front of the dash panel, a front subframe disposed below the pair of front side members, and an electric motor mounted on the front subframe, wherein a front edge of the electric motor is pivotally connected to the front subframe, and a rear edge of the electric motor is pivotally connected to the dash panel.

A vehicle body front structure includes: a front side frame extending in a longitudinal direction of a vehicle body; a side frame disposed laterally outside the front side frame in a vehicle width direction and extending in the longitudinal direction of the vehicle body; and a damper housing disposed laterally inside the side frame in the vehicle width direction. The side frame extends obliquely in a frontward and downward direction from a bent portion formed in proximity to the damper housing, and has a rectangular cross-section formed by a U-shaped member having a generally U-shaped cross-section and a lid member disposed on an open side of the U-shaped member. A first bendable portion is formed at a front end portion of the side frame by setting a strength of the lid member lower than a strength of the U-shaped member.

A front vehicle-body structure is provided that is lightweight and reduces an impact load transmitted to lower limbs of an occupant. Embodiments include a transmission disposed in a vehicle front portion, a dash lower panel dividing an inside from an outside of a vehicle cabin in a vehicle rear of the transmission, and an organ type accelerator pedal disposed on a vehicle-width-direction inner side of the dash lower panel opposed to the transmission. The dash lower panel includes a panel rear portion in which the accelerator pedal is arranged, a panel front portion extending from the panel rear portion to a vehicle front upper side, and a fragile portion extending in a vehicle width direction along a boundary between the panel rear portion and the panel front portion, which is fragile compared to the panel rear portion and the panel front portion.

The support stiffness of a suspension supporting portion can be improved to reduce floor vibration. Arm front-end supporting portions, each supporting a front end portion of a trailing of a rear suspension, are formed on lower portions of rear frames extending in a vehicle longitudinal direction, and each include a squared U-shape portion including outer, inner and front wall portions, with a rear side being open when viewed from the bottom, and an extending outer wall portion extending from the outer wall portion to in front of the front wall portion. The outer wall portion and extending outer wall portion are formed by a side sill inner portion joined to each rear side frame. Also, each arm front-end supporting portion includes an extending inner wall portion extending from the inner wall portion to in front of the front wall portion and joined to each of the rear side frames.

A lower structure of a vehicle includes front side frames, a vehicle body strength member, a floor panel, and a power supply unit, in which the front side frames are formed to have cross-sectional shapes that open upward at least at rear sections thereof, the power supply unit is disposed below a floor panel, the floor panel includes a pair of reinforcing panel portions which are respectively joined to the rear sections of the front side frames and cover the rear sections from above, and a floor panel main body portion which constitutes a portion other than the reinforcing panel portions, and the reinforcing panel portions are formed to have higher strength than the floor panel main body portion.

A structural panel joining part for a vehicle having an underbody hold-down panel, a floor panel, a dash panel, and a cowl side panel includes an underbody coupling first portion configured to couple to at least one of the underbody hold-down panel and the floor panel, a dash panel coupling second portion configured to couple to the dash panel, and a cowl side coupling third portion configured to couple to the cowl side panel. The structural panel joining part maintains structural integrity between the underbody hold-down panel, the floor panel, the dash panel, and the cowl side panel to provide structural reinforcement during small overlap rigid barrier impacts to facilitate reducing structural intrusion into an occupant compartment of the vehicle.

A vehicle body structure and a vehicle are provided. The vehicle body structure includes a front longitudinal beam, a front compartment crossbeam, and a dash panel. The front longitudinal beam includes a left front longitudinal beam and a right front longitudinal beam that are disposed at an interval in a transverse direction. The front compartment crossbeam is mounted on the left front longitudinal beam and the right front longitudinal beam, and is located in front of the dash panel. A projection area of the front compartment crossbeam on the dash panel in an X direction at least partially covers a projection of a preset area surrounding a pedal center point on the dash panel in the X direction.
