A vehicle body front structure of a vehicle is provided. The vehicle is equipped with a bumper beam disposed on a front side of a vehicle body and extending in a vehicle width direction. The bumper beam is fixed at its lateral end portions in the vehicle width direction to the vehicle body. A guide member is disposed on each lateral end portion of the bumper beam to cover a laterally outer end surface of the bumper beam in the vehicle width direction. The guide member has a deformation allowance caused to extend in a collision in accordance with a displacement of the bumper beam.

Vehicle body front structure

A vehicle body front structure includes: a front side frame extending in a longitudinal direction of a vehicle body; a side frame disposed laterally outside the front side frame in a vehicle width direction and extending in the longitudinal direction of the vehicle body; and a damper housing disposed laterally inside the side frame in the vehicle width direction. The side frame extends obliquely in a frontward and downward direction from a bent portion formed in proximity to the damper housing, and has a rectangular cross-section formed by a U-shaped member having a generally U-shaped cross-section and a lid member disposed on an open side of the U-shaped member. A first bendable portion is formed at a front end portion of the side frame by setting a strength of the lid member lower than a strength of the U-shaped member.

A vehicle front structure includes: a pair of left and right front pillars; a front wall portion provided between the pair of left and right front pillars and forming a front end of the vehicle interior; a lower wall portion extending rearward from a lower end of the front wall portion; a tunnel member formed at a middle portion of the lower wall portion in a vehicle width direction and having an upward convex shape; and a reinforcing portion laminated on and fixed to the front wall portion or the front wall portion and the lower wall portion, in which the reinforcing portion is provided so as to be inclined downward from the front pillar toward the tunnel member and forms a thick plate portion in collaboration with the front wall portion or the front wall portion and the lower wall portion.

Vehicle front structure

A vehicle body for contributing to weight reduction of a structure of a front part while preventing a front bumper beam from falling off is provided. A vehicle body includes: pairs of left and right support bodies, being disposed on the left and the right with an accommodation space of a power unit interposed therebetween, extending in a vehicle body forward-rearward direction, and having joint surfaces displaced rearward as the joint surfaces going outward in a vehicle width direction while facing the front; a front bumper beam, extending in a vehicle body lateral direction across the front of the accommodation space and being joined to the joint surfaces at both ends thereof; and engagement members, extending forward from inner sides of the joint surfaces in the vehicle width direction and engaging with the front bumper beam in the forward-rearward direction at least at a time of a collision.

Vehicle body

The disclosure provides a vehicle body capable of well preventing the deformation of a side door even if the weight of the vehicle itself increases. The vehicle body includes a front pillar upper which extends rearward and upward along a side edge of a windshield, a front pillar lower which is joined to a lower end of the front pillar upper to support a front end of the side door, a dash upper side which connects an upper member to the front pillar lower while being joined to the front pillar upper at a rear extension part, and a front pillar upper stiffener which reinforces the bending rigidity of the front pillar upper. A distance is set between the rear extension part of the dash upper side and a front end of the front pillar upper stiffener above the front pillar lower.

A shock absorbing member of the present disclosure is a shock absorbing member including a first hollow member () and a second hollow member () that are made of aluminum alloy and are weld joined to each other, in which a weld material and weld beads (W) do not project from a side on which a joined surface between the first hollow member () and the second hollow member () is located.

Shock-absorbing member

A bumper structural body () includes a bumper reinforcement (), energy absorbing members (), and intermediate members (). The sloped sections () of the bumper reinforcement () are connected to the energy absorbing members () and the intermediate members (). The intermediate members () are each formed in a quadrilateral by connecting a first portion () contacting the energy absorbing member (), a second portion () contacting the bumper reinforcement (), and portions connecting the first portion () and the second portion ().

Bumper structural body

An object of the present invention is to provide a vehicle body floor structure capable of effectively preventing deformation of a floor panel by increasing bending strength of the floor panel even when an upper reinforcing member of the floor panel is removed. A vehicle body floor structure of the present invention includes a dash cross member disposed along a kick-up portion on a lower surface side of a floor panel, a novel front side frame having an outer frame and an inner frame at a rear portion of a side frame body, and a floor panel on which beads are formed to form a closed cross-section in cooperation with the outer frame and the inner frame.

Vehicle body floor structure

A vehicle body front structure includes: a bracketthat is placed on a lower portion of a front side frame; and a front subframethat is attached to a lower portion of the bracket with a bolt. The bracket includes: a closed-end hollow bracket bodythat is suspended from the front side frame; a bulkheadthat is located above a bottom plateof the bracket body and vertically partitions the bracket body; and a collarthat extends from the bulkhead to the bottom plate of the bracket body. A thickness tof the bulkhead is smaller than a thickness tof the bracket body. The bulkhead joined to the bracket body has a bulkhead-side flangejoined to the front side frame.
