Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a vehicle body front structure having a cab side integral structure in which the side body door opening and its surroundings are integrally molded.

(Prior Art) A side body serves as a structural member forming a side surface of a passenger compartment in a body shell, and has the role of suppressing deformation of the vehicle body in the event of an overturn, and ensuring durability and strength.

Here, conventionally, in order to easily assemble the side body, each member constituting the outer side of the side body, especially the hinge pillar outer panel around the door opening and the side sill outer panel, etc., were integrally molded. A vehicle body structure with an outer body shape has been proposed. For example, Japanese Patent Publication No. 47-10329 discloses an example of such an integrated vehicle body structure.

(Problems to be Solved by the Invention) However, in such an integral structure, the strength of the corner portions may not be sufficient.
In particular, at the joint between the side sill outer frame that extends in the longitudinal direction of the vehicle body and the hinge pillar outer frame that extends in the vertical direction of the vehicle body in the lower part of the vehicle body, stress concentration occurs at the corner where these two members are integrally molded. It is difficult to take measures such as forming only a thick member, and strength is likely to be insufficient.

An object of the present invention is to provide a suitable reinforcing structure for such corner portions.

(Means for Solving the Problems) To this end, in the present invention, among the members constituting the outer part of the side body of an automobile, at least a side sill outer panel extending in the longitudinal direction of the vehicle body and a hinge pillar outer panel extending in the vertical direction of the vehicle body are combined. The structure includes a cowl side panel joined to the front side of the vehicle body of the hinge pillar outer panel in a state where the outer surface of the vehicle body substantially coincides with the outer surface of the vehicle body of the hinge pillar outer panel, and the side sill is integrally formed with the cowl side panel. One end of the outer panel and the hinge pillar outer panel is joined from the front and rear sides of the vehicle body, respectively, with a front wall formed by bending the outer surface of the hinge pillar outer panel inward of the vehicle body sandwiched therebetween. The present invention is characterized in that it includes first and second horizontal reinforcing members extending rearward.
