The rear panel includes a peripheral edge frame structure which is provided at an upper part of the bumper beam, and which has a closed cross-sectional structure. An upper projection of the bumper beam is in contact with a panel of the peripheral edge frame structure.

To actively absorb impact energy by a bead and reduce weight. A vehicle body rear structureof an embodiment includes rear floor panelsandformed by a steel plate having a tensile strength of 440 MPa or more. The rear floor panelsandhave beadsandextending in a predetermined direction over an entire surface, and the direction in which the beadsandextend and the type of the beadsandare set so as to reduce a difference between a peak load and an average load at the time of collision.

Provided is a vehicle equipped with a battery pack. A vehicle equipped with a battery pack includes a battery pack under a floor of the vehicle. The battery pack is provided with a battery module. In the battery module, a plurality of batteries are arranged vertically with the longitudinal direction directed toward a front-rear direction of the vehicle body. The battery is formed by stacking a plurality of battery cells in the front-rear direction of the vehicle body. A center of gravity of pack of the battery pack is arranged at the rear of a center of gravity of vehicle of the entire vehicle in the vehicle body.

A vehicle body structure includes: a second floor cross member and a third floor cross member in which one end in a vehicle width direction is connected to a side sill; a battery arranged below the second floor cross member and the third floor cross member; a battery case which stores the battery and in which one end in the vehicle width direction is connected via a right frame and a left frame; cross member bent portions formed on the second floor cross member and the third floor cross member; and frame bent portions formed on the right frame and the left frame. The cross member bent portions and the frame bent portions are arranged side by side in an up-down direction.

A vehicle-mounted battery pack includes a battery tray including a floor part, a right frame, and a left frame. The battery tray includes a battery disposition region, a right impact-absorbing region, and a left impact-absorbing region. A battery module is placed in a battery disposition region. The left and right impact-absorbing regions are provided on outer sides of the battery disposition region in the vehicle width direction. The right frame and the left frame are formed to be thinner than the right and left impact-absorbing regions. Further, an easily deformable portion is formed at a lower portion of the right and left impact-absorbing regions.

Vehicle-mounted battery pack

Provided is a vehicle equipped with a battery pack. A vehicle equipped with a battery pack includes a floor tunnel and a battery pack. The battery pack includes a first battery accessory, a second battery accessory, and an electrical wiring. The first battery accessory is arranged inside a front tunnel portion of the floor tunnel from below. The second battery accessory is arranged inside a rear tunnel portion of the floor tunnel from below. The electrical wiring extends in a front-rear direction of a vehicle body across right and left second floor cross members, and connects the first battery accessory and the second battery accessory.

In a vehicle body structure including a pair of side sills () and a battery case () joined to the side sills via respective brackets (), each side sill includes an outer panel (), an inner panel () defining a closed cross section structure jointly with the outer panel, a first stiffener () extending in the fore and aft direction in a space defined between the outer panel and the inner panel and having a lower edge joined to the lower edges of the outer panel and the inner panel, and a second stiffener () formed as a channel member extending in the fore and aft direction and having an open side facing in the inboard direction, the second stiffener having an upper edge and a lower edge attached to an outboard side of the first stiffener.

A structure for a lower portion of a vehicle body includes a right side sill (), a right floor frame (), a right cross member (), and a muffler. A fuel tank is provided on an inner side of the right floor frame () in a vehicle width direction. The right cross member () spans between the right floor frame () and the right side sill () and extends in the vehicle width direction. Furthermore, the muffler is provided in a region enclosed by the right side sill (), the right floor frame (), and the right cross member (). The right cross member () has an upward deformation guiding part (). The upward deformation guiding part () is formed to be able to be deformed upward due to an impact load (F) input to the right side sill ().
