Embodiment Construction

[0034] Hereinafter, the vehicle front structure will be described with reference to the drawings. figure 1 It is a schematic longitudinal sectional view of the front structure of the vehicle. in addition, figure 2 yes figure 1 A schematic cross-sectional view at height position A in . In addition, in figure 1 , figure 2 In , only the components particularly associated with the lower energy absorber 20 are shown.

[0035] Such as figure 1 As shown, the front end of the vehicle is covered by a bumper cover 10 . This bumper cover 10 constitutes the exterior design surface of the vehicle front. The rear space of the bumper cover 10 serves as a power unit chamber 14 in which a power unit (for example, an engine, an electric motor, a drive battery, etc.) generating power for vehicle running is disposed. In addition, a front grill 12 for guiding air outside the vehicle to a power unit chamber 14 is incorporated in the bumper cover 10 . As is well known, the front grille 12...

Abstract

A vehicle front portion structure includes a lower absorber (20) installed in a lower region of a vehicle front portion and having a longer length in a width direction of a vehicle, at least one loadbearing member (50, 60) disposed on a rear side of the lower absorber (20) and connected to the lower absorber (20) so as to receive a load transferred from the lower absorber (20), in which at leasta part of the lower absorber (20) is equipped with a reinforcement member (32), and the reinforcement member (32) is formed, in cross section, in a shape of substantially a wave composed of a series of upward protruding parts (34u) protruded upward of the vehicle and downward protruding parts (34d) protruded downward of the vehicle, the upward and downward protruding parts alternating along the width direction of the vehicle.

Description

[0001] The entire disclosure of Japanese Patent Application No. 2017193862 filed on October 3, 2017 including specification, claims, drawings, and abstract is hereby incorporated by reference in its entirety. technical field [0002] This specification discloses a vehicle front structure including a long lower energy absorber in the width direction of the vehicle and one or more load-resistant members receiving loads from the lower energy absorber. Background technique [0003] Conventionally, many techniques have been proposed for reducing the damage received by the collision body when the collision body (for example, a pedestrian's leg, etc.) collides with the front of the vehicle. For example, Patent Document 1 discloses a bumper energy absorber that is crushed more reliably when an impact is received by devising the shape of the bead of the bumper energy absorber installed at the front of the vehicle. Absorbs collision energy, thereby protecting pedestrians. [0004] In...
