Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cowl top coupling structure in an automobile in which a body is divided into upper and lower parts.

(Prior Art) In an ordinary automobile, as shown in FIGS. 7 and 8, the front pillar a has a vertically integrated structure, and cowls are provided on the front edges d and e of the inner panel b and the outer panel c thereof. The rear edge flange g of the top component f is joined by spot welding, while the lower edge flange i of the cowl top side panel h of the cowl top component f and the side edge flange k of the cowl top inner panel j are connected to the front. Spot welding s is performed by spot welding n on an upper edge flange m bent outward in the vehicle width direction at an upper edge portion of a front extension l located below the front edge portion d of the pillar inner panel b. They are joined together.

By the way, Japanese Patent Application Laid-Open No. 61-92965 proposes an automobile in which a body is divided into upper and lower parts, and after the fitting work in the body is completed in an open state, the both bodies are connected using a fastener. In this case, among the cowl top constituent members shown in FIG. 7, the cowl top side panel h is divided into the upper body side and the cowl top inner panel j is divided into the lower body side, and the side of the cowl top inner panel j in the bottom portion is divided. The edge flange k and the upper edge flange m of the front extension l are previously joined by spot welding, and the lower edge flange i of the cowl top side panel h is connected to the side edge flange k and the upper edge flange m at the time of body joining. A cowl top connection structure in which a fastener is used for connection is conceivable.
In addition, o is a front fender and p is a dash panel.

(Problems to be solved by the invention) By the way, in FIG. 7, various interior parts such as a computer are installed in a space A formed by the cowl top inner panel j, the front extension l, and the dash panel p. Therefore, a large installation space is required.

However, in the above coupling structure, the upper edge flange m is formed to be bent outward in the vehicle width direction of the front extension portion l, and the front extension portion 1 is located inside the upper edge flange m in the vehicle width direction. There is a problem that the space A is narrowed by the dimension of the edge flange m in the vehicle width direction, so that a sufficient installation space for interior parts cannot be secured.

In order to solve this problem, it is conceivable to bulge the front extension 1 outward in the vehicle width direction to expand the space A, but even in this case, the flanges of the three parties are extended outward in the vehicle width direction of the front extension l. Since it is necessary to secure a working space for coupling the parts using a fastener, the bulging portion and the shape of the front extension part 1 are restricted, and it is also difficult to secure a sufficient installation space.

In the case of the vehicle type in which the space A is formed by the cowl top inner panel j, the dash panel o, and the side edge extension portions thereof, the side edge extension portions are located inside the top edge flange in the vehicle width direction. Have the problem of.

In view of the above problems, the present invention provides a space formed by a cowl top inner panel, a front extension of the front pillar inner panel and a dash panel, or a cowl top inner panel, a dash panel, and It is an object of the present invention to provide a cowl top coupling structure for an automobile, in which a space formed by the side edge extension portion is enlarged to allow a sufficient installation space for interior parts.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention divides a body into upper and lower parts, and a lower edge flange of a cowl top side panel located on an upper body side is a lower front part located on a lower body side. A cowl top for an automobile, which is joined by using a fastener at a joint between a front edge extension of a pillar inner panel or a side edge extension of a dash panel and a side edge flange in a bottom edge formation portion of a cowl top inner panel. In the coupling structure of No. 2, the upper edge flange in the front extension of the lower front pillar inner panel or the side extension of the dash panel is formed by bending inward in the vehicle width direction.

(Operation) According to the above configuration, as shown in FIG. 1, the upper edge flange 4b of the front extension 4a of the lower front pillar inner panel 4 is formed.
By being formed by bending inward in the vehicle width direction,
Since the front extension 4a can be located outside the upper edge flange 4b in the vehicle width direction, the front extension 4a, the cowl top inner panel 5, and the dash panel 34 are correspondingly disposed.
The space A formed by can be enlarged, and a sufficient installation space for interior parts can be secured.

Moreover, since the upper edge flange 4b can be positioned in the space A by this, the shape of the front extension 4a in the above configuration is the work of connecting the three flanges 10a, 5a, 4b using the fastener 31. As a result of being able to design without space constraints, it is possible to easily take a sufficient installation space.

The space A is, as shown in FIG. 6, a cowl top inner panel 5, a dash panel 34, and a side extension portion thereof.
Even in the case of a vehicle type formed by 34a, the upper edge flange 34b of the side extension 34a is formed by being bent inward in the vehicle width direction, thereby expanding the space A and providing a sufficient installation space. be able to.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS.
