Vehicle body structure and method for assembling vehicle body structure

Abstract

A vehicle body structure (1) comprises roof side rails (20), a roof arch (4), and a roof panel (5). The roof side rails (20) have placement sections (26) which extend inward in the width direction of the vehicle and on which the outer ends (5A) of the roof panel (5) in the width direction of the vehicle are placed. The outer ends (4A) of the roof arch (4) in the width direction of the vehicle are located further toward the outer sides in the width direction of the vehicle than the inner ends (26A) of the placement sections (26) in the width direction of the vehicle, are joined to the roof side rails (20), and are disposed at positions separated downward from the outer ends (5A) of the roof panel (5) in the width direction of the vehicle. The roof arch (4) and the roof side rails (20) have flange sections (24, 25, 43, 44) in contact with the other to prevent the downward movement of the roof arch (4). The flange sections (24, 25, 43, 44) are located above the outer ends (4A) of the roof arch (4) in the width direction of the vehicle.

Description

technical field [0001] The present invention relates to a vehicle body structure and a method of assembling the vehicle body structure. Background technique [0002] Conventionally, a roof panel constituting the upper surface of the vehicle body is provided between a pair of side members that are arranged on the left and right sides of the vehicle body and constitute the side parts of the vehicle body, and a roof panel for reinforcing the vehicle including the roof panel is provided. The roof arch of the upper part of the body. [0003] Figure 14 (a) is a longitudinal sectional view cut along the vehicle width direction, showing a partially cutaway vehicle body structure of the conventional example of Patent Document 1, Figure 14 (b) is a longitudinal cross-sectional view cut along the vehicle width direction, showing a partially cutaway vehicle body structure of the invention of Patent Document 1. [0004] For example, if Figure 14 As shown in (a), as a conventional exa...

AI Technical Summary

Problems solved by technology

[0017] However, in the invention described in the above-mentioned Patent Document 1, there is a problem that the strength and rigidity are reduced due to the portion where the cross-sectional shape is squeezed. On the other hand, in the invention described in the above-mentioned Patent Document 2, there is Expansion parts and strut reinforcement parts are required, and the number of parts increases, so the number of joints increases accordingly, and the strength and rigidity cannot be ensured appropriately
