Abstract

The invention provides a vehicle body structure effective for protection of a pedestrian and absorption of the collision load while ensuring the cooling performance. The vehicle body structure comprises a lower member (42) connected to fore ends (2a, 3a) of a pair of front side members (2, 3) extending in the back and forth direction FR of a vehicle body and arranged in the vehicle width direction W, and a bumper beam (4) located above the lower member (42) and forming an opening part (7) by an upper member (41) connected to the fore ends (2a, 3a). The strength of the upper member 41 is set to be lower than that of the lower member (42).

Description

technical field [0001] The present invention relates to a vehicle body structure, in particular to a vehicle body structure that absorbs a collision load in front of the vehicle body, and further relates to a vehicle body structure equipped with a collision detection sensor. Background technique [0002] In Japanese Patent Application Laid-Open No. 2004-330948, a vehicle body structure is proposed in which a bumper beam is offset above with respect to a front side member while connecting the front end of the front side member below. The offset configuration of the longitudinal beam connecting member connects the bumper and the longitudinal beam connecting member to the front longitudinal beam via a common connecting member. [0003] In the case of a vehicle having an engine in front of the vehicle body, it is conceivable to provide a large opening in the front of the vehicle body in order to supply a larger amount of cooling air to the engine. In order to achieve this purpo...
