Problems solved by technology

[0003] However, the impact load acting on the front side member is not only from the front, but also from the side. Therefore, in the structure described in the above-mentioned Patent Document 1, if there is an impact If the load acts on the front side beam from the side, it may cause deformation of the connection part of the dash panel connected to the front side beam and its surrounding parts, which will cause the front side beam to move in the vehicle width direction with the connection part as the fulcrum. Medial collapse

Abstract

The vehicle front body structure of the present invention has a gusset (50), and the gusset (50) is connected to the front side member ( 30) The connecting part and the above-mentioned hinge pillar (20), the gusset (50) and the face of the engine room (2) side of the dash panel (11), along the vehicle compartment of the dash panel (11) ( 3) The closed cross-sectional structure on the side of the vehicle compartment formed by the side surface and the reinforcing member (40), forming a closed cross-sectional structure on the side of the engine compartment. According to the present invention, even when an impact load acts on the front side member (30) from the side, the front side member (30) can be prevented from collapsing inwardly.

Description

technical field [0001] The invention relates to a front body structure of a vehicle, belonging to the technical field of body structures. Background technique [0002] The front body of a vehicle is generally provided with a dash panel separating the vehicle compartment and an engine room, and hinge pillars (hinge pillars) which are joined to the left and right side edges of the dash panel and have a closed cross-sectional structure extending in the vertical direction. , and a pair of left and right front side members extending forward from the dash panel on the inner side of the hinge strut in the vehicle width direction. As a structure for distributing the impact load acting on the front side member from the front, Japanese Patent Laid-Open Publication No. Hei 4-74185 (hereinafter referred to as "Patent Document 1") discloses the following technical solution. The vehicle compartment side of the panel is connected to the above-mentioned hinge strut and the side member conn...
