A front vehicle-body structure of a vehicle that enables smooth compressive deformation of a front side frame from the front side thereof on a vehicle frontal collision portion. The front vehicle-body structure of a vehicle includes a pair of left and right front side frames extending in a vehicle front-rear direction is characterized in that each of the front side frames is formed such that a rear side portion has a higher rigidity than a front side portion, and rigidity differences are alternately formed in the vehicle front-rear direction in each of regions of the front side portion and the rear side portion.

A vehicle frame structure includes a pair of side members located on both right and left sides of a vehicle, each of the pair of side members extending both forward and rearward of a cabin along a respective side of the cabin. As each of the pair of side members extends in a longitudinal direction at a substantially uniform height, a load applied to one end can be transferred toward the other end.

Upper frames and a lower frame that connect a rear end of a coupled body composed of a side sill and a rear pillar and a rear side housing to each other are spaced apart in a vehicle up-down direction. An inclined angle at which a lower frame is inclined to be closer to a vehicle inner side toward a vehicle rear side is larger than inclined angles at which the upper frames are inclined to be closer to the vehicle inner side toward the rear side. A lower joined portion to which a rear end of the lower frame is joined is on a vehicle-width-direction inner side with respect to an upper joined portion in the rear side housing, which is composed of a single member including at least the lower frame rear-end joined portion, and the first and second upper frame rear-end joined portions, and extending therebetween.

A vehicle body may include a floor; a pair of side sills connected to first and second side edges of the floor, respectively; and a cross unit mounted on the floor and extending in a width direction of a vehicle, wherein the cross unit includes a lower crossmember connecting the pair of side sills, an upper crossmember disposed above the lower crossmember, a first reinforcement member disposed between the lower crossmember and the upper crossmember, and a pair of second reinforcement members connected to first and second end portions of the first reinforcement member, respectively.

A vehicle mounting structure for an electric unit 1 includes a side member 10, a suspension member 5 including a high rigidity portion 5a and a low rigidity portion 5b in a vehicle front-rear direction, and an electric unit 1 in which an inverter 2 and a motor 3 are integrated. The side member 10 includes a curved portion 10c having an upwardly convex curved shape. The curved portion 10c is disposed at a position overlapping with the inverter 2 in the vehicle front-rear direction. The electric unit 1 is fixed to the low rigidity portion 5b.

An embodiment vehicle front structure includes a pair of front side members, a pair of fender upper members located above the pair of front side members, respectively, a bumper back beam connecting front ends of the pair of front side members, and a front end module connected to the pair of front side members and the pair of fender upper members.

A vehicle-body structure of a vehicle of the present invention comprises a bumper support portion provided at a vehicle body of the vehicle to support to bumper, a connection portion connecting the bumper and the bumper support portion and supporting the bumper, and a slide allowance portion configured to allow the bumper to slide in a vehicle longitudinal direction relative to the bumper support portion when a longitudinal load having a specified magnitude or larger is applied to the bumper from a vehicle outside, wherein the connection portion is provided on an upper face of the bumper support portion, and the slide allowance portion is configured to allow the longitudinal sliding of the bumper independently from the supporting of the bumper by the connection portion.

A vehicle includes a floor including a lower floor on which a high-voltage electric component is arranged and an upper floor which is arranged on an upper side of the lower floor. The vehicle includes a seat and a base. The seat is arranged above the high-voltage electric component and includes a leg portion. The base is fixed to the lower floor and is arranged on an inside in a vehicle width direction. The leg portion includes: a first leg portion that is fixed to the upper floor; and a second leg portion that is fixed to the base.

A vehicle includes a vehicle frame, a vehicle bumper and a load transfer assembly. The vehicle bumper is coupled to a front end of the vehicle frame and includes a center beam and a bumper beam extension that extends laterally from an end of the center beam. The load transfer assembly includes first and second pivot pins and a load beam. The first pivot pin is fixed to the bumper beam extension and the second pivot pin is fixed to the vehicle frame. The load beam has a first end pivotably coupled to the first pivot pin and a second end pivotably coupled to the second pivot pin. The load beam is configured to load the vehicle frame in a lateral direction upon a vehicle impact event.

A front vehicle body structure includes a front side member that is connected to a front mounting bracket, and a front side upper member that is spaced apart from the front side member in the vehicle body width direction. The front side upper member is also connected to the front mounting bracket.
