Embodiment Construction

[0026] Fig. 1 shows the three-dimensional situation of the vehicle body structure of an embodiment of the present invention, and Fig. 2 shows the detailed situation of the arrow II part among Fig. 1, Fig. 3 shows the outward appearance of connecting plate, Fig. 4 is IV-IV line view among Fig. 2, Fig. 5 shows the appearance seen from the cabin side with the instrument panel removed.

[0027] As shown in FIG. 1 , the left and right sides of the front of the compartment S of the vehicle have a pair of front pillars 1 extending in the vertical direction of the vehicle, and the front pillars 1 are joined to the base ends of a pair of left and right upper frames 6 extending forward of the vehicle. . A pair of left and right front pillars 1 are connected by a cowl top 2 extending in the vehicle width direction, and below the cowl top 2, there is arranged a space between the cabin S and the area in front of the cabin (in the case of a front-engine vehicle). The following is the engin...

Abstract

A vehicle body structure in which a side member (5) and an instrument panel (3) are reinforced and bonded in a state where a disengagement force acting on a joint portion due to an input from a side of the vehicle body is relaxed. Join the front and back (11a) of the connecting plate (11) by welding on the front and rear (8a) of the strut (8), and the transverse face (11b) of the connecting plate (11) and the transverse face of the strut (8) ( 8b) Overlapping welding joint, the extension plate portion (11c) extending to the front surface (3a) side of the instrument panel (3) is joined to the front surface (3a) of the instrument panel (3) by welding, thereby passing through the connecting plate ( 11) Combine the strut (8) and the instrument panel (3) so that the input to the front surface (3a) of the instrument panel (3) is eased with respect to the input from the side of the stringer (5) transmitted to the strut (8). The stress concentration transmitted by the engaging portion of the front surface (3a) is relaxed, and the disengagement force acting on the engaging portion engaged with the front surface (3a) is eased.

Description

technical field [0001] The present invention relates to a body structure incorporating a side member extending toward the front of a cabin of a vehicle and an instrument panel. Background technique [0002] A pair of side members forming a vehicle frame are arranged to extend in the front-rear direction of the vehicle. The cabin of the vehicle and the area in front of the cabin (in the case of a front-engine vehicle, the engine room: hereinafter referred to as the engine room) are separated by an instrument panel, and the side member is combined with the instrument panel. In addition, the engine room has a support base for supporting the suspension member, and the structure of the engine room including the support base and the like is supported by a pair of side beams. [0003] The vibration input from the support base is transmitted to the longitudinal beam, and the input from the support base is transmitted to the joint between the longitudinal beam and the instrument pan...
