An embodiment is a vehicle body including a vehicle body skeleton including a tail gate frame and a rear side member connected to a lower portion of the tail gate frame, a chassis frame including a longitudinal frame disposed in the length direction of the vehicle body, and a vehicle body rear connection structure configured to connect the vehicle body skeleton and the chassis frame, wherein the longitudinal frame is connected to an intersecting position of the lower portion of the tail gate frame and the rear side member.

An embodiment rear vehicle body structure of a vehicle including an underbody and an upper body coupled to the underbody includes a reinforcing member coupled to an upper surface of a rear floor panel provided on the rear side of the upper body and connected to both chassis frames of the underbody through the rear floor panel.

A rear panel extending in a vehicle width direction at a rear portion of a vehicle, and a rear in-panel extending in a vehicle front-rear direction on a vehicle width direction side surface of the rear portion of the vehicle are provided. The rear panel includes: a rear panel body extending in the vehicle width direction, and a front extension portion bent and extended from an outer side of the rear panel body in the vehicle width direction toward a front side. The front extension portion and the rear in-panel are connected to form a side surface of a luggage room.

A structure for reinforcing and supporting a vehicle frunk includes front side members installed in a front-to-back direction of a vehicle body at both sides of a front floor panel of a vehicle, a frunk bar extending in a width direction of the vehicle between the front side members and connected to the front side members, a bracket formed at a position corresponding to connection between the frunk bar and a respective one of the front side members, to couple the frunk bar to the respective one of the front side members, at least two motor mounts formed beneath the frunk bar in a height direction of the frunk bar, and a subframe positioned beneath the motor mounts in a height direction of the motor mounts and connected to the front side members to extend in the width direction of the vehicle.

In a vehicle body rear part structure, a plurality of first spot weld parts that join the rear panel inner flange and the rear panel outer flange by spot welding are provided at a first weld pitch; a plurality of second spot weld parts that join together the rear pillar inner flange and the rear pillar outer flange by spot welding are provided at a second weld pitch; at the corner part, a plurality of third spot weld parts that join together, by spot welding, regions of the rear panel inner flange, the rear panel outer flange, the rear pillar inner flange, and the rear pillar outer flange where at least three of the flanges overlap with one another are provided at a third weld pitch; and the third weld pitch is set to be shorter than the first weld pitch and the second weld pitch.

Falling-in deformation, in which a second quarter pillar deforms so as to fall toward a vehicle vertical direction lower side, is suppressed. Due to twisting input being applied to a vehicle, a second quarter pillar deforms so as to fall toward the vehicle vertical direction lower side. A connecting member, whose lower end portion is joined to a joined region of a wheel house and a lower end portion of a first quarter pillar, receives this falling-in deformation of the second quarter pillar. Accordingly, because the connecting member, whose lower end portion is securely fixed, receives the falling-in deformation of the second quarter pillar, the falling-in deformation of the second quarter pillar is effectively suppressed.

A motor vehicle includes a body, which body has at least two rear longitudinal members each forming a primary load path for collision forces, wherein the motor vehicle has a rear-end module that can be pre-assembled as a sub-assembly, which rear-end module can be connected to the body as part of the vehicle assembly after the completion of the body-in-white and has at least a supporting structure for fastening chassis components of a rear wheel suspension and a beam structure extending from the supporting structure toward the motor-vehicle rear for absorbing collision forces, wherein the supporting structure and the beam structure form at least one second load path for collision forces.

A vehicle body frame includes a first vertical bead portion (38) adjacent to an inner ridge line (54), a first strain development region (39) defined by an arc (67) of a minimum distance (L1) between the first vertical bead portion (38) and an outer ridge line (55), a second vertical bead portion (41) adjacent to the outer ridge line (55), and a second strain development region (42) defined by an arc (68) of the minimum distance (L1) between the second vertical bead portion (41) and the inner ridge line (54).

There is provided a vehicle rear portion structure that can improve torsional rigidity of a rear body that has side members and a cross member. A bracket has a top wall portion to which an HV (high voltage) battery is fixed. Further, the bracket has a first leg portion, that extends from a front end portion of the top wall portion toward a vehicle lower side and that is fixed to a first rear cross member, and a second leg portion, that extends from a vehicle transverse direction outer side end portion of the top wall portion toward the vehicle lower side and that is fixed to a rear side member.

A vehicle includes a hood at a front end, a frunk under the hood, and a cabin. The vehicle includes a cross-beam positioned between the frunk and the cabin, and configured to inhibit protrusion of the frunk into the cabin in a frontal impact. The vehicle also includes a frame and the cross-beam is coupled to the frame. The cross-beam is a unitary member that is coupled to the frame or the cross-beam includes two members separated by a gap and each member is coupled to the frame. The frame includes shock towers for coupling the cross-beam to the frame. The frame can also include a bracket for coupling the cross beam to the frame.
