Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cowl panel lip structure, and more particularly, to a cowl panel lip structure which ensures the rigidity of the rear end of the cowl panel and improves the followability of the window glass surface.

[0002]

2. Description of the Related Art A cowl panel having a grid-like or slit-like air introduction hole is disposed between a windshield and a hood of an automobile. While introducing outside air into the vehicle cabin, it is designed to prevent the ingress of dust, fallen leaves and the like.

FIG. 3 is a perspective view of a cowl panel portion, FIG. 4 is a sectional view taken along line AA in FIG. 3, and FIG. 5 is a portion B in FIG. It is an enlarged view. A cowl panel 1 is mounted between the hood F and the window glass 2 in front of the vehicle body as shown in the figure.
As shown in FIGS. 4 and 5, a lip 3 is provided on the cowl panel side of a portion where the cowl panel 1 and the window glass 2 are joined.
Is installed. The lip is constructed by attaching a separate lip to the cowl panel as shown in FIG. 5,
Alternatively, those formed integrally with a cowl panel (Japanese Patent Application Laid-Open Nos. 6-72134 and 8-72748).
The lip 3 has a function of preventing the intrusion of water droplets on the glass surface and the appearance of the mating portion between the window glass and the cowl panel.

In recent years, the number of parts has been reduced by, for example, integrally molding a cowl panel generally formed of a hard synthetic resin and a molding portion (hereinafter referred to as a lip) formed of a soft synthetic resin. (Japanese Unexamined Patent Publication No.
19145) has also been proposed.

[0005] By the way, the cowl panel is usually fixed to the vehicle body at a plurality of places. However, as described above, recently, the cowl panel is also formed of a PP material as a molded body of about t = 3 mm. Therefore, it cannot be said that the rigidity is high over the whole, and since it is generally a size close to the width of the vehicle, the cowl panel alone has a relatively soft and soft structure. For this reason,
In the middle of the fixing portion of the cowl panel, for example, there is a possibility that the temperature will rise due to a rise in temperature in summer, so that it is usual to fix it with clips or the like over as many points as possible.

[0006]

However, due to the structure of the vehicle body, the cowl panel is not always fixed at a position close to the glass, and the number of mounting points has to be reduced depending on the structure of the vehicle body. As a result, the fit between the window glass and the lip may be deteriorated, and a means for improving the fit between the window glass and the lip has been required.

Therefore, in order to secure the rigidity of the cowl panel and to improve the followability of the lip to the window glass surface, the present invention forms a lip having a molding function at the rear end of the cowl panel in contact with the window glass, and further forms a lip. It is an object of the present invention to solve the above-mentioned problem by providing a cowl panel lip structure in which a rib for reinforcing a rear end portion of the cowl panel is formed at a connection portion between the cowl panel and the cowl panel.

[0008]

For this purpose, the present invention employs a reinforcing rib on a rear surface of a rear end portion of a cowl panel disposed in front of a front end portion of a window glass in a vehicle width direction. A cowl panel lip structure, wherein a lip extending toward the window glass is disposed at a portion reinforced by the rib. The rib has a cowl panel lip structure provided over the entire rear surface of the rear end of the cowl panel. Further, the rib has a cowl panel lip structure, wherein the rib is provided to be inclined with respect to the back surface of the cowl panel. Further, the lip has a cowl panel lip structure formed integrally with the cowl panel. Further, the rib and the lip are formed integrally with the cowl panel, and a flexible portion is formed at a boundary portion between the cowl panel and the lip.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a cowl panel molding according to the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view corresponding to the AA cross section of FIG. 3 shown in FIG. It is an enlarged view of the C section in FIG. The same reference numerals are used for the same members as in the conventional example.

In the drawing, reference numeral 1 denotes a cowl panel, which is formed of a hard synthetic resin, and is integrally formed at the rear end of the cowl panel 1 with a synthetic resin of the same material as the cowl panel as shown in FIG. Are formed to fill the cowl panel 1 in the vehicle width direction. The reinforcing ribs 4 are attached to the rear surface of the cowl panel 1 at an angle in order to prevent contact with the lower end of the window glass 2 during assembly. The rib 4 and the cowl panel 1
A lip 3 made of a soft synthetic resin and having a molding function is integrally formed over the entire width direction of the vehicle body at a connection portion forming a boundary portion between the cowl panel 1 and the lip. A concave portion 5 that facilitates bending of the base of the lip is formed in the connecting portion to form a flexible portion. A dam rubber 7 is attached to the vehicle body at the lower end of the window glass 2 so as to face the vehicle body panel 6.

In the cowl panel lip structure configured as described above, the lip 3 having a molding function is formed at the rear end of the cowl panel 1 disposed adjacent to the window glass 2 via the concave portion 5 so that the lip 3 can be assembled. In the lip 3
Follows the two surfaces of the window glass well and looks good.
By forming a rib 4 for reinforcing the rear end of the cowl panel 1 near the connection between the lip 3 and the cowl panel 1, sufficient rigidity is ensured even for a cowl panel using a PP material. be able to. In addition, inconveniences such as swelling due to temperature rise in summer can be eliminated.

Although the lip described in the above embodiment has been described as being formed integrally with the cowl panel, the lip and the cowl panel do not necessarily need to be integrated, and a separate lip may be used as a cowl. It goes without saying that it may be configured to be mounted on the rear end of the panel. Further, the rib provided on the cowl panel may be formed of a different material inserted into the cowl panel, and the rib may be provided only at a necessary portion without necessarily being provided on the entire rear surface of the cowl panel.

[0013] The present invention may be embodied in any other form without departing from its spirit or essential characteristics. Therefore, the above-described embodiment is merely an example in all aspects and should not be interpreted in a limited manner.

[0014]

As described in detail above, according to the present invention, a lip is formed integrally with the cowl panel at the rear end of the cowl panel arranged adjacent to the window glass.
Since a concave portion that facilitates bending of the lip is formed in the connection portion between the lip and the cowl panel, the lip follows the window glass surface well during assembly, and the appearance is improved.
In addition, at the connection between the lip and the cowl panel, a rib for reinforcing the rear end of the cowl panel, which was attached with an inclination to the back surface of the cowl panel, to prevent contact with the terminal under the window glass during assembly, By forming, even if it is a cowl panel using a PP material, sufficient rigidity can be ensured, and even if there is a temperature rise in summer, it is possible to eliminate inconveniences such as the cowl panel being deformed and rising. And excellent effects such as can be achieved.
