Description

The connection structure between the front windshield and the front wall louver

technical field

The utility model relates to a connection structure between a front windshield and a front wall louver.

Background technique

In the prior art, a structure in which a cowl louver is arranged between an automobile hood and a front windshield has been widely adopted. Usually, between the cowl louver and the front windshield, there is a connection structure for connecting the rear end portion of the cowl louver and the front end portion of the front windshield.

The connection structure between the above-mentioned front windshield and the dash louver includes a rear end of the dash louver, a sealing body disposed on the rear end of the dash louver, and a front windshield disposed below the sealing body The front end of the glass. The sealing body has a fitting portion assembled to the rear end portion of the cowl louver, and a fin-shaped sealing sheet extending from the fitting portion toward the rear of the vehicle. The sealing sheet is in contact with the surface of the front end portion of the front windshield.

The fitting portion is configured to have a U-shaped cross section and to sandwich the rear end portion of the cowl louver. Specifically, the fitting portion has a top wall portion, a bottom wall portion, and a connecting portion connecting the top wall portion and the bottom wall portion. A convex portion protruding downward is formed on the lower side of the top wall portion of the fitting portion. On the top surface of the rear end portion of the cowl louver, a concave portion which can be fitted with the convex portion of the fitting portion is formed.

When the user presses the cowl louver downward to move the cowl louver downward relative to the front windshield, so that the connecting wall of the assembling part of the sealing body is subjected to a load, the U-shaped opening end of the assembling part will be deformed and There is a possibility that the sealing body may come off from the rear end portion of the cowl louver due to the expansion.

The second convex portion 612 extends in the vehicle width direction and has an arc-shaped cross section. Moreover, the 2nd convex part 612 is located in the part close|similar to the connection part 61c of the bottom wall part 61b. Therefore, the second convex portion 612 is closer to the rear side of the vehicle than the first convex portion 611 .

The connecting portion 61c integrally connects the top wall portion 61a and the bottom wall portion 61b, and is closer to the rear side of the vehicle than the rear end surface 42c of the rear end portion 42 of the cowl louver 4. The shape of the connecting portion 61c corresponds to the rear end surface 42c of the cowl louver 4, and the cross section thereof is an arc shape.

The sealing body 6 is assembled to the rear end portion 42 of the cowl louver 4 by fitting the first convex portion 611 with the first concave portion 421 and the second convex portion 612 with the second concave portion 422 . Here, thermal fusion bonding is not used between the sealing body 6 and the rear end portion 42 of the cowl louver 4 .

<Operation when the cowl louver is pressed>

3 and 4 , the connection structure 50 between the front windshield and the cowl louver of the present embodiment will be described when the cowl louver 4 is pressed downward by the user.

When the cowl louver 4 is pressed downward by the user, as shown in FIG. 3 , the cowl louver 4 moves to the front and downward direction (D direction) of the vehicle relative to the windshield 2 . Then, as shown in FIG. 4 , the overlapping portion between the rear end portion 42 of the cowl louver 4 and the front end portion 21 of the windshield 2 is reduced, but when the load (reaction force) from the windshield 2 ) acts on the connecting portion 61c of the fitting portion 61 of the sealing body 6, the second convex portion 612 of the sealing body 6 is engaged with the second concave portion 422 of the cowl louver 4, so that the opening end of the fitting portion 61 does not will deform and open.

＜Benefits＞

In the present embodiment, as described above, the second recess 422 is formed on the bottom surface 42b of the cowl louver 4, and the second recess 422 is formed on the bottom wall 61b of the sealing body 6 to fit into the second recess 422. Since the front shroud louver 4 is pressed downward by the user, the windshield glass 2 is moved obliquely downward (D direction) relative to the dash louver 4, so that the connecting part of the fitting part 61 of the sealing body 6 is formed. When a load is applied to the 61c, the second convex portion 612 of the sealing body 6 is engaged with the second concave portion 422 of the cowl louver 4, so that the sealing body 6 can be prevented from falling off from the rear end portion 42 of the cowl louver 4. Furthermore, by assembling the sealing body 6 to the cowl louver 4, compared with the structure in which the sealing body and the cowl louver are thermally welded, the cost can be reduced, and the waterproof performance can be improved.

In addition, in the present embodiment, by configuring the second convex portion 612 and the second concave portion 422 to have arc-shaped cross sections, even when the positions of the second convex portion 612 and the second concave portion 422 are displaced, the second convex portion 612 and the second concave portion 422 can be displaced. The second convex portion 612 and the second concave portion 422 are properly abutted (joined).

In addition, in the present embodiment, by configuring the rear end surface 42c of the cowl louver 4 to have a curved shape, the fitting portion 61 of the sealing body 6 can be easily inserted into the rear end portion 42 of the cowl louver 4. Therefore, even if The second convex portion 612 is formed on the bottom wall portion 61b, and the sealing body 6 can also be easily assembled to the cowl louver 4 .
