STRUCTURE FOR FRONT SECTION OF VEHICLE BODY

摘要

Provided is a structure for the front section of a vehicle body, the structure being made of at least fiber-reinforced resin and comprising as constituent elements an upper section that extends in the width direction of the vehicle in an upper part of the structure, a lower section that extends in the width direction of the vehicle in a lower part of the structure, two side sections that are connected to the upper section and the lower section on both ends thereof in the width direction of the vehicle and extend in the height direction of the vehicle body, and upper side sections that extend from both ends of the upper section in the rearward direction of the vehicle body. The upper section is configured as follows: a) a first portion, excluding the central section in the extension direction of the upper section, has a roughly U-shaped cross-section open in the rearward direction of the vehicle body; b) the first portion is configured to have an integrated structure of a metal frame with a roughly L-shaped cross-section that has a wall that follows the upper surface and the vertical surface of the roughly U-shaped cross-section and a fiber-reinforced resin frame with an approximately U-shaped cross-section that has a wall that follows the upper surface, vertical surface and lower surface of the roughly U-shaped cross-section; and c) a second portion, which is the central section in the extension direction of the upper section, has an extension section of the metal frame that has a wall that follows at least the extended surface of the upper surface and the extended surface of the vertical surface of the roughly U-shaped cross-section at the first portion, and the extension section of the metal frame constitutes an upper section formation section made solely of metal. The weight of the frame cross-section at the central section of the upper section, which collides with a pedestrian, is made lighter, making it possible to realize a structure for the front section of a vehicle body having excellent pedestrian-protecting properties that can reduce the force of impact received by a pedestrian from the structure for the front section of the vehicle body when a collision occurs.
