Description

[Detailed description of the invention] This invention relates to a rubber hood seal for automobiles.

Generally, automobile hood seal rubber is used to seal between the hood that closes the opening of the car body and the car body to prevent rainwater from entering the opening, and the above opening is the opening of the engine room. In this case, it also has the function of preventing the hot air in the engine room from escaping to the outside.
It was as disclosed in Publication No. 55-31732. The hood seal rubber has the purpose of sealing between the hood and the vehicle body, and also has the purpose of urging the periphery of the hood outward to prevent its vibration. Further, due to the layout, this hood seal rubber is sometimes attached to the vertical wall of the opening edge of the vehicle body. In this case, in order to increase the biasing force, the thickness of the lip portion that comes into contact with the hood is increased. However, when the hood is closed, a so-called waving phenomenon occurs in which the entire seal rubber is significantly deformed between the adjacent clips that secure the hood seal rubber to the vehicle body, and the hood between the adjacent clips is Since the seal rubber moves up and down while rubbing against the hood seal rubber mounting surface of the vehicle body, there was a problem that the paint in that area would peel off.

This idea was made in view of the problems of the conventional ones as described above, and includes a base that is fixed to the vertical wall of the car body extending downward from the opening edge of the car body with a plurality of locking members, and an upper end of the base. A thin part is provided near the connecting part with the lip part that extends from the hood toward the inside of the vehicle body opening and comes into contact with the hood when the hood is closed, and a protrusion is provided inside the opening below the thin part at the upper end of the base side. The lip part is provided so as to protrude toward the thin wall part, and when the hood and the lip part come into contact, the protrusion part comes into contact with the lower end of the lip part and restricts the deflection of the lip part. It is an object of the present invention to provide a hood seal rubber for an automobile, which can be easily bent, and can prevent large bending of the seal rubber as a whole by the projections, thereby preventing the occurrence of waving.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a vehicle body opening to which a hood seal rubber according to an embodiment of the present invention is attached, and FIGS. 2 and 3 show a partially sectional perspective view and a sectional view of the above embodiment. In the figure, an engine room 2 is formed in the front part of a car body 1, and the engine room 2
An opening 3 is formed in the upper part of the hood for maintenance and inspection of an engine (not shown), etc., and a hood 4, which is a hood for opening and closing the opening 3, is attached to the opening 3 so as to be openable and closable.

Further, a hood seal rubber 5 is attached along the periphery of the opening 3, and the hood seal rubber 5
As shown in FIG. 3b, clips 6 are fitted into a plurality of engagement holes 5b formed in the center of a base 5a having a substantially arcuate cross section, and are attached to a cowl grille 1a and a cowl panel 1b, which are part of the vehicle body 1. It is installed and fixed as shown. A lip portion 5d is integrally formed on the upper part of the base portion 5a, facing upward and inside the opening 3 (top left in FIG. 3), and the connection portion of the lip portion 5d with the base portion 5a is provided with a lip portion 5d. A thin wall portion 5e is formed with a reduced wall thickness. Further, a protrusion 5f is integrally formed on the lower side of the thin portion 5e, that is, on the upper end of the base 5a, facing inward of the opening 3.
Further, a locking portion 5c having an L-shaped cross section is integrally formed at the lower end of the base portion 5a, and the locking portion 5c is connected to the locking portion 1 formed at the lower end of the cowl grille 1a.
It is locked with c.

Next, the effects will be explained. First, when the bonnet 4 is opened, the lip portion 5d faces upward and inside the opening 3, as shown by solid lines in FIGS. 3a and 3b. Next, when the bonnet 4 is closed, the tip of the lip portion 5d is pressed by the peripheral edge of the bonnet 4, and is bent downward as shown by the two-dot chain line in FIG. At this time, a thin portion 5 is provided at the bottom of the lip portion 5d.
e is formed, the lip portion 5d is easily bent, and no large force is applied to the base portion 5a.
The entire hood seal rubber 5 does not bend significantly and wave. Further, a protrusion 5f is formed at the upper end of the base 5a, and when the deflection of the lip portion 5d increases to a certain extent, the lip portion 5d is removed from the protrusion 5f.
Since the bonnet 4 contacts the bonnet 4 and does not bend any further and urges the periphery of the bonnet 4 upward, vibration of the bonnet 4 can be prevented. Further, since the cross section of the base portion 5a is approximately arcuate, and the area in contact with the cowl grille 1a is small, the paint on this portion will not peel off.

In the above embodiment, the base portion 5a of the hood seal rubber 5 has a substantially arc-shaped cross section, but the cross-sectional shape of the base portion is not limited to the substantially arc shape, but may be any other suitable shape.

Further, in the above embodiment, the hood seal rubber that seals between the bonnet 4 that opens and closes the opening 3 of the engine room 2 and the vehicle body 1 has been described.
The present invention is applicable not only to the above-mentioned case but also to the case of sealing between a vehicle body and a trunk lid that opens and closes an opening of a trunk room, for example.

As described above, according to the automobile hood seal rubber according to the present invention, since the vicinity of the connecting portion between the base of the hood seal rubber and the lip portion is thinned, the lip portion is easily bent when the hood and the lip portion come into contact, and the base portion is It is possible to prevent the waving of the base between the locking members, which is a problem when fixing to the vertical wall of the car body with a plurality of locking members, and the peeling of the paint on the vertical wall of the car body due to the vertical movement of the base. Furthermore, since a protrusion is formed on the upper end of the base to restrict the deflection of the lip, when the deflection of the lip increases to a certain extent, the lower end of the lip comes into contact with the protrusion formed on the base. Since the hood is biased upward, it has the effect of suppressing the vibration of the hood.
