Description

[Detailed explanation of the idea] Industrial applications The present invention relates to the front structure of an automobile body.

BACKGROUND TECHNOLOGY As is well known, at the front of an automobile body, an engine compartment is constructed by joining a dart lower panel, cowl box, left and right hood ribs, etc. The cabin side of this engine compartment is equipped with a steering shaft, an accelerator pedal, and an engine compartment. Functional parts such as the brake pedal, clutch pedal, air conditioner unit, and instrument panel are assembled. The instrument panel is formed to bulge rearward in side view, and its upper front edge is attached to the cowl box, and its side parts are attached to the front pillar lower section.

In the case of automobile bodies, for example, as shown in Japanese Unexamined Patent Application Publication No. 61-92965, in order to achieve automatic assembly of the car body and automatic assembly of functional parts and interior parts, the car body is assembled into individual body component parts. It is known that the so-called modularization of the vehicle body is done by dividing the vehicle body into parts and assembling them on separate lines, equipping each vehicle body component with functional parts and interior parts, and then joining and integrating them into one body.

Problems that the invention aims to solve When modularizing a car body as described above, the car body is divided into an engine compartment, left and right body side assemblies including front, center, rear pillars, side sills, roof side rails, and rear fender panels. and front roof rail,
It is conceivable to divide the roof assembly into a roof assembly including a rear roof rail and roof panel, a floor assembly, and a rear end assembly to further improve the ease of assembling functional parts and interior parts. However, the structure is such that the instrument panel is connected across the engine compartment and the left and right body side assemblies. Therefore, in the engine compartment before the left and right body side assemblies are assembled, only the upper front edge of the instrument panel is attached to the cowl box, so the instrument panel can be moved vertically around the upper front edge. There is a risk of damage due to rotation. In addition, the side part of the cowl box is a drainage channel that drains water that has entered the cowl box to the outside of the vehicle, so the panel alignment structure prevents water from entering the cabin side from the side part of the cowl box. There is. Therefore, when assembling the left and right body side assemblies and the engine compartment, it is necessary to move the left and right body side assemblies from the rear to the front to place the side portions of the cowl box on the waist portions of the front pillars. For this reason, if the structure in which the side parts of the instrument panel are screwed to the left and right body side assemblies remains, when the left and right body side assemblies are assembled with the engine compartment, Since the instrument side stay must be overlapped and placed on the back of the side part of the instrument panel from between the dart lower panel and the instrument panel, the movement of the robot's arm is restricted during automatic assembly of the vehicle body. The operation control becomes complicated.

SUMMARY OF THE INVENTION Therefore, the present invention provides a structure for the front body of an automobile, which allows the instrument panel to be securely assembled into the engine compartment, and also allows easy adjustment of the upright position of the instrument panel and automatic assembly of the vehicle body.
