JP 2004-155351 A

  In the above-described prior art, a negative pressure is generated on the upper surface of the hood during high-speed driving due to the shape of the hood and the layout of the engine and auxiliary equipment stored under the hood, and the hood may be lifted upwards of the vehicle. . At this time, there is a possibility that a gap is generated between the hood and the cowl portion, and hot air in the engine room leaks from the gap, causing a problem that the windshield hits the windshield.

  Therefore, an object of the present invention is to provide a vehicle body front structure that can improve the sealing performance between the hood and the cowl portion.

  The present invention has been made in view of the above circumstances, and a seal member for sealing between the hood and the cowl cover is provided, and a space is provided between the cowl cover and the cowl panel. The vehicle body front structure is characterized in that an elastic body that elastically deforms with the hood closed and biases the cowl cover upward is provided.

  When the hood is closed, the seal member and the elastic body are elastically deformed, and by the reaction force, the cowl cover is biased upward by the elastic body, and the seal member seals between the hood and the cowl cover. The

  Therefore, when the hood is lifted upward by a negative pressure during high-speed traveling, in addition to restoring the seal member, the elastic body is restored, the cowl cover is lifted, and the distance between the hood and the cowl cover is narrowed. Thus, since the cowl cover is raised and the distance between the hood and the cowl cover is narrowed, the maintenance performance of the sealed state is improved as compared with the case where only the seal portion is restored. Therefore, it is possible to suppress the hot air from leaking from the gap between the hood and the cowl cover and fogging the front window glass.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

It is a vehicle body front structure provided with a hood (7) that is disposed in front of the cowl cover (6) so as to be able to be opened and closed, overlapping the vehicle upper portion of the portion (6a).

  In the vehicle body front structure of this embodiment, a seal member (8) is provided between the hood (7) and the cowl cover (6) to seal between the two, and the cowl cover (6) A space (B) is provided between the cowl panels (31, 32), and the space (B) is elastically deformed with the hood (7) closed, so that the cowl cover (6) is located above the vehicle. An elastic body (9) for biasing is provided.

  The vehicle body front part structure of Example 1 of the best mode for carrying out the invention will be described with reference to FIGS.

  First, the configuration will be described.

  As shown in FIG. 2, the vehicle body 1 is provided with a cowl box 3 extending in the vehicle width direction at the upper end of a dash panel 2 that partitions the engine room ER and the vehicle compartment R. Both ends of the cowl box 3 in the vehicle width direction are coupled to the front pillars 4 and 4.

  The cowl box 3 supports the lower edge portion of the front window glass 5, and the vehicle upper side surface is covered with a resin or metal cowl cover 6 that is an exterior product.

  The engine room ER is covered with a hood 7. The hood 7 is supported by the vehicle body 1 so that the engine room ER can be opened and closed, and the rear end portion or the front end portion thereof is turnable by the vehicle body 1.

  Further, a rubber seal rubber 8 as a seal member is interposed between the vehicle front end edge 6 a of the cowl cover 6 and the hood 7.

  An elastic body 9 is interposed between the front end edge 6 a of the cowl cover 6 and the cowl box 3.

  Details of the above structure will be described with reference to FIG. 1, which is a sectional view taken along line S1-S1 of FIG.

  The cowl box 3 is formed in a box cross-sectional shape by connecting a dash upper panel 21 that forms the upper part of the dash panel 2, a cowl lower 31 as a cowl panel, and a cowl upper 32 by three flanges 33, 34, and 35. .

  A lower edge portion of the front window glass 5 is attached to the flange 34 by bonding or the like.

  The cowl cover 6 has a vehicle rear end edge portion 6b bonded to the upper surface of the lower edge portion of the front window glass 5, while the vehicle front side end edge portion 6a is cantilevered so as to be movable in the vehicle vertical direction. It has become. The front edge 6a of the cowl cover 6 is disposed so as to overlap the hood 7 and the flange 33 of the cowl box 3 in the vertical direction, and between the hood 7 and the cowl upper 32. The spaces A and B are respectively set and arranged.

  The seal rubber 8 is disposed in the space A and attached to the upper surface of the vehicle front side edge portion 6a of the cowl cover 6 by bonding or the like. The seal rubber 8 is formed in a hollow shape, and a lip 8a is formed at a portion that contacts the hood 7.

  On the other hand, the elastic body 9 is disposed in the space B and is attached to the lower surface of the vehicle front side edge portion 6 a of the cowl cover 6 and the flange 33 of the cowl box 3.

The elastic body 9 is formed of a stainless steel leaf spring, exhibits a restoring force even when repeatedly subjected to a reaction force, and has excellent heat resistance, and with respect to its elastic deformation amount. magnitude of the reaction force generated is set to a size corresponding to the reaction force generated against the initial elastic deformation of the sealing rubber 8.

  Further, as shown in the enlarged cross-sectional view of FIG. 3, the elastic body 9 is formed in a substantially U-shaped cross section by an upper piece 9a, an intermediate piece 9b, and a lower piece 9c. A bent portion 9d is formed that is bent in a substantially U shape in order to improve stretchability. The elastic body 9 has an upper piece 9 a engaged with an engaging claw 6 c integrally formed on the back surface of the cowl cover 6, and the lower piece 9 c is made of a resin clip 91 on the flange 33 of the cowl box 3. It is attached with.

Then, the vehicle vertical dimension of the sealing rubber 8, and the vehicle vertical dimension of the elastic member 9, respectively are, when closed off over de 7, respectively, set to a dimension that is elastically deformed by a predetermined amount in the compression direction Has been.

  Next, the operation of the first embodiment will be described.

Normally, when the hood is closed, as shown in FIG. 1, the seal rubber 8 and the elastic body 9 are compressed and deformed, and the reaction force causes the seal rubber 8 to contact the hood 7 to seal between the two. Yes. Here, since the reaction force generated with respect to the elastic deformation amount of the elastic body 9 is set to the same magnitude as the reaction force generated with respect to the initial elastic deformation amount of the seal rubber 8, it is elastic with the seal rubber 8. The body 9 is compressed and deformed almost equally. Therefore, the contact pressure between the seal rubber 8 and the hood 7 becomes less than the set value and the sealing performance is deteriorated, or an excessive reaction force is input to the seal rubber 8 and only the seal rubber 8 is excessively compressed. Does not occur.

  Next, as shown in FIG. 4, the hood 7 may be lifted upward from the normal position indicated by a two-dot chain line by the traveling negative pressure P generated on the upper surface of the hood 7 during high-speed traveling. At this time, as the hood 7 is lifted upward, both the seal rubber 8 and the elastic body 9 are deformed in the extending direction, which is the restoring direction. Therefore, the vehicle front side edge portion 6 a of the cowl cover 6 is raised, and the seal rubber 8 is kept in a sealed state in contact with the hood 7.

  Therefore, the hot air in the engine room ER does not leak toward the front window glass 5, and clouding due to the leakage of the hot air does not occur.

  Next, when the seal rubber 8 has deteriorated over time and the reaction force of the seal rubber 8 itself has weakened and a reaction force sufficient to seal the hood 7 cannot be obtained, the reaction force of the seal rubber 8 The elastic body 9 is stretched and deformed by the reduced amount. That is, as shown in FIG. 5, the vehicle front side edge portion 6a of the cowl cover 6 is raised by the extension of the elastic body 9, and the vertical dimension of the space A is narrowed while the vertical dimension of the space B is expanded. The seal rubber 8 is kept in a sealed state in contact with the hood 7.

  Next, as shown in FIG. 6, when an impact load F is input to the hood 7 from above the vehicle, the hood 7 crushes the seal rubber 8 and the elastic body 9. Thus, in Example 1, when the impact load F is input, the reaction force of the elastic body 9 is generated in the direction opposite to the input direction and the hood 7 is elastic compared to the conventional structure having no elastic body 9. The body 9 can be bent as much as the space B in which the body 9 is installed, and the impact absorption performance can be improved.
