Description

This invention relates to a vehicle body structure. Patent Document 1 discloses a front structure for an automobile, comprising a cowl extending in the vehicle width direction and positioned along the lower edge of the automobile's windshield, and a dash panel connected to the lower part of this cowl to separate the passenger compartment from the engine compartment. In this structure, a plate-shaped dash panel is fixed to the outside of the front lower side wall of the cowl by several appropriate spot welds. Japanese Patent Publication No. 2009-113568 This is a perspective view showing the front part of the vehicle body structure according to the embodiment.This is a perspective view showing the body components of a vehicle body structure according to an embodiment.This is a front view showing the body components of a vehicle body structure according to an embodiment.This is a side view showing the body components of a vehicle body structure according to an embodiment. The following describes embodiments of the vehicle body structure 100 according to the present invention with reference to Figures 1 to 4. In each figure, arrows FR indicate the front of the vehicle in the longitudinal direction, arrow RH indicates the left side of the vehicle in the width direction, and arrow UP indicates the upper side of the vehicle in the vertical direction. In the following description, the longitudinal direction, width direction, and vertical direction refer to the longitudinal direction, width direction, and vertical direction of the vehicle, respectively. The left-right direction refers to the left-right direction when the vehicle is facing forward. [vehicle] The vehicle to which the body structure 10 according to this embodiment is applied is, for example, a battery-powered electric vehicle (BEV). However, the vehicle to which the vehicle side structure 10 according to this embodiment can be applied is not limited to BEVs. For example, the body structure 10 according to this embodiment may be applied to a fuel cell vehicle or the like. [Vehicle body structure] The vehicle body structure 10 according to this embodiment is provided at the front of the vehicle. As shown in Figures 1 and 2, the vehicle body structure 100 comprises a front vehicle body 10 and vehicle body components 20 attached to the front vehicle body 10. [Front of the vehicle] The front section 10 of the vehicle body is a structural component of the front of the vehicle. As shown in Figure 1, the front section 10 of the vehicle body includes a dash section 12, a front pillar section 14, a front side member section 16, and a suspension tower section 18. The front section 10 of the vehicle body is made of die-cast aluminum, and the dash section 12, front pillar section 14, front side member section 16, and suspension tower section 18 are integrally formed. The dashboard 12 is located at the front and bottom of the vehicle. The dashboard 12 separates the interior space S1 (the inside of the passenger compartment) from the front compartment S2 (the outside of the passenger compartment). More specifically, the dashboard 12 separates the lower part of the interior space S1 from the lower part of the front compartment S2. The rearward-facing surface of the lower part of the dash section 12 is an inclined surface 12A, with the upper side positioned towards the front of the vehicle more than the lower side. The inclined surface 12A is located below the instrument panel (not shown). The rearward-facing surface of the upper part of the dash section 12 is a vertical surface 12B extending approximately vertically in the vehicle's vertical and vehicle width directions. Front pillar sections 14 are connected to both ends of the dash section 12 in the vehicle width direction, and the pair of left and right front pillar sections 14 extend in the vehicle vertical direction. Specifically, the lower part of the front pillar section 14 extends in the vehicle longitudinal direction, and a rocker, a structural member (not shown), is connected to the rear end of the front pillar section 14. The front pillar section 14 extends diagonally from its rear end towards the upper and front of the vehicle, and is configured to transmit the load acting on the front of the vehicle body 10 in the vertical direction of the vehicle. A pair of left and right front side member sections 16 extend from both ends of the dash section 12 in the vehicle width direction toward the front of the vehicle. The front side member sections 16 extend in the vehicle's longitudinal direction and are configured to transmit loads input from the front of the vehicle to the rear of the vehicle. A suspension tower section 18 is provided on the outer side in the vehicle width direction of each of the left and right front side member sections 16. The suspension tower section 18 is located above the front side member sections 16 and is configured to support a suspension (not shown). [Vehicle body components] The veh
