Embodiment Construction

[0036] Such as figure 1 , figure 2 and image 3 As shown, the vehicle 10 is a four-door passenger car, and a front engine compartment 21 and a vehicle compartment 26 located directly behind the engine compartment 21 are formed inside a vehicle body 13 .

[0037] The vehicle body 13 is constituted by a monocoque body, and is formed in a bilaterally symmetrical shape with respect to a vehicle width centerline CL extending in the vehicle front-rear direction passing through the vehicle width center of the vehicle 10 . The vehicle body 13 has front door openings 17 , 17 and rear door openings 18 , 18 on left and right side surfaces, respectively. The front and rear door openings 17 and 18 are opened and closed by vehicle doors not shown. A power unit 22 is arranged in the engine room 21 . The power unit 22 is composed of an engine and a transmission. Left and right front wheels 24 , 24 are suspended from left and right side portions of a front portion 28 of the vehicle body ...

Abstract

The invention provides a vehicle body structure, which reduces the weight of the left and right side sills while ensuring the strength of the left and right side sills. A vehicle body (13) includes hollow left and right side sill (66, 66). Front ends of the side sills are formed into closed cross sections and substantially inverted-L shapes. The front end (66f) of the right side sill is bilaterally symmetrical to the front end of the left side sill. Rear ends (66r) of the left and right side sills are formed into substantially square-shaped cross sections. Portions (66m) from the front ends to the rear ends of the side sills are formed into closed cross sections which change smoothly from the inverted-L shaped cross sections to the square-shaped cross sections.

Description

technical field [0001] The present invention relates to a vehicle body structure in a vehicle such as a passenger car. Background technique [0002] The left and right side sills of the vehicle body are located on the left and right sides of the vehicle body and extend in the front-rear direction. It is desired that the left and right side sills can secure a certain strength and ensure collision force absorption performance in any of the following three cases. The first case is that of a so-called frontal collision in which a collision force acts on the front of the vehicle. The second case is that of a so-called rear-end collision in which collision forces act on the rear of the vehicle. The third case is a so-called side collision in which a collision force acts on the lateral side of the vehicle in the width direction. [0003] For example, when a side collision occurs in the vehicle, the collision force from the side acts on the center pillar extending upward from the...
