A side body structure of a vehicle can include: a hinge pillar; a front pillar that is coupled to an upper end portion of this hinge pillar via a bent section, extends upward to the rear, and is coupled to a front end portion of a roof side rail via a connected section; and an apron rein that extends forward from a position below the bent section in the hinge pillar, where the bent section can include an energy absorption section that is subjected to out-of-plane deformation in a longitudinal orthogonal direction of the front pillar and thereby can absorb collision energy when the collision energy, which can be directed rearward, is applied to the apron rein. The energy absorption section can be configured to include an outer bead section and an inner bead section respectively provided in an outer member and a lower inner member.

An embodiment vehicle body coupling structure of a vehicle that includes an underbody and an upper body coupled to the underbody includes a front back beam assembly provided on a front side of the underbody, a first mounting part provided on a front side member of the upper body and coupled with the front back beam assembly, and a first body coupling part provided on the front back beam assembly and engaged with the first mounting part.

Provided is a vehicle body structure in which when a load acts on an impactor, the impactor is moved toward an inner wall, a slider is moved along the inner wall by means of direction-changing unit, and in the case where the load acting on a crushing member via the slider exceeds a set value, the moving slider crushes the crushing member.

A vehicle side structure (102; 202) comprising a side portion (104; 204) extending in a longitudinal direction (106; 206), wherein the side portion (104; 204) comprises a first member (108; 208) extending in the longitudinal direction (106; 206) and a second member (110; 210) extending in the longitudinal direction (106; 206). The first member (108; 208) is configured to face an inside (112; 212) of a vehicle, and the second member (110; 210) is configured to face an outside (114; 214) of the vehicle. The first and second members (108, 110; 208; 210) are attached to one another to form a substantially closed space (116; 216) between them. The side portion (104; 204) comprises two wave-shaped reinforcement members (118, 120; 218, 220) located in the substantially closed space (116; 216). The reinforcement members (118, 120; 218, 220) are attached to one another.

An under body structure of an automobile enabling batteries to be mounted on an automobile by a simple configuration and efficiently transferring load at the time of a collision, that is, an under body structure 100 of an automobile provided with a body floor 110 forming a floor part of the automobile and batteries 50 (battery cells or battery modules) directly suspended from and fastened to a bottom side of the body floor 110.

A method is for producing a three-dimensional vehicle door frame inner reinforcement element (52) including an inner center pillar part (66), an inner front pillar part (68) and an inner side rail part (64) joining the inner center pillar part (66) and the inner front pillar part (68). The method includes providing an inner center pillar blank, an inner front pillar blank and an inner side rail blank, said inner blanks being substantially planar, assembling the inner center pillar blank and the inner front pillar blank to the inner side rail blank in order to form a substantially planar door frame inner reinforcement blank, and hot stamping the door frame inner reinforcement blank to shape the three-dimensional door frame inner reinforcement element (52).

A vehicle includes a body including a first frame rail and a second frame rail and a cross-brace directly connected to the first frame rail and the second frame rail. A powertrain-electrification component is supported by the cross-brace. A vehicle subframe is directly connected to the cross-brace. A vehicle-steering gear is connected to the subframe. The direct connection of the subframe to the cross-brace dampens vibration, e.g., road vibration and noise, in the subframe to reduce noise, vibration, and harshness transferred to a vehicle occupant through the vehicle-steering gear.

An electric vehicle structure may include a floor panel; a center tunnel disposed at a center of the floor panel in a vehicle width direction, extending along a vehicle front-rear direction, and projecting upward from the floor panel; a dash panel disposed at front ends of the floor panel and the center tunnel; and a front reinforcement attached to an inner surface of a peripheral wall of the center tunnel and extending rearward from the dash panel through the center tunnel.
