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.

Vehicle frame structure

Each of a monocoque body and a subframe is integrally formed of reinforced resin. The subframe has a bottom portion and an upstanding portion. The bottom portion is fixed to the lower portion of the rear wall of the monocoque body and extends rearward of the vehicle. The upstanding portion extends upward from the bottom portion. An engine is directly mounted on the rear surface of the upstanding portion.

Monocoque vehicle structure

A vehicle hood structure capable of improving impact absorption ability prior to a secondary impact when an impacting body impacts the hood. Front end portions of beads of a wave shaped section are arranged in a line in hood plan view. A front wall section is provided further to the hood front side than the wave shaped section and is formed inclined towards the hood bottom side on progression towards the hood front and running substantially along the vehicle width direction. The wave shaped section and the front wall section are connected together by a ledge section formed running substantially along the hood width direction.

Vehicle hood structure

A hood structure that is for a vehicle and that can cause an increase in energy absorption performance when colliding with a collided object. An undulating section wherein beads and concavities are provided in alternation along the widthwise direction of the hood and that has a wavy shape in a cross sectional view is formed at nearly the entire central region of a hood inner panel. In the cross section of the wavy shape of the undulating section, the widthwise measurement between the peaks of the beads that are formed on both adjacent sides of any given bead aside from the two on the ends among the plurality of beads is set in a manner so as to be smaller than 165 mm, which is the outer diameter of a head impactor that simulates the head of a pedestrian.

A hood inner panel that is provided with plural wave-shaped portions that extend in a vehicle longitudinal direction is provided at a vehicle lower side of a hood outer panel. A lock reinforcement is disposed at a lower side of a vehicle front of the hood inner panel. Front end portions of the plural wave-shaped portions of the hood inner panel are positioned further toward a vehicle front side than a rear end portion of the lock reinforcement.

A vehicle hood structure capable of both raising the energy absorbing ability when an impacting body has impacted a hood and enhancing deformation properties of the hood during a frontal collision. A framework formation section configuring a central region in a hood inner panel is provided with beads and indented portions formed to extend along the hood front-rear direction. Plural through holes are formed at a hood front-rear direction substantially central portion of the framework formation section in a row along the hood width direction. The through holes are formed in bottom portions of the indented portions. Beads are also formed in the two hood width direction edge portions in positions aligned with the hood front-rear direction positions of the through holes.

A weak portion (connection release device) is provided in an upper connection portion in which a headlamp, which is a lamp, is connected to a radiator support, which is a vehicle body, and therefore, when an impact load is applied from above a vehicle, an upper portion of the headlamp is detached from the radiator support. In a lower connection portion in which a lower portion of the headlamp is connected to a bumper reinforcement, which is a vehicle body, a lower connection device maintains a connection between the lower portion of the headlamp and the bumper reinforcement. When the impact load is applied in a longitudinal direction of the vehicle, the lower connection device releases the connection between the headlamp and the bumper reinforcement.

Lamp mounting structure and vehicle to which lamp is mounted with the use of the same

A bumper absorber includes an upper leg and a lower leg, each of which extends in a longitudinal direction of an automobile, and a spanning portion. The spanning portion connects the upper leg and the lower leg, and faces an outer surface side of the bumper absorber in a longitudinal direction of the automobile. Each of the upper leg and the lower leg includes a buckling inductive portion that serves as a starting point of the buckling that is caused when the spanning portion receives an impact load. The buckling inductive portion is formed as an angular transition portion in which the angle of inclination between inner side surfaces changes. The inner side surfaces mutually face between the upper leg and the lower leg that include the buckling inductive portion.
