The same components are denoted by the same reference numerals, and overlapping descriptions are omitted. When the direction is described, unless otherwise indicated, it is basically described based on the front and rear, left and right, or up and down as viewed from the driver. In addition, "vehicle width direction" and "left-right direction" are synonymous.

FIG. 1 shows a configuration in the vicinity of a cowl box portion 6 in a vehicle 1 to which the cowl top structure according to the embodiment of the present invention is applied. A hood panel 2 (refer to FIG. 2 ) covering the upper part is provided in the upper opening of the engine room E provided in the front part of the vehicle body.

Moreover, the glass panel 3 is provided in the front of the vehicle compartment R. As shown in FIG. Further, the cowl box portion 6 is arranged rearward of the rear end 2 a of the hood panel 2 and extends in the vehicle width direction below the front end 3 a of the glass panel 3 .

The cowl box portion 6 includes the upper instrument panel 4 , the glass support 7 supporting the front end 3 a of the glass panel 3 , and the cowl top cover 10 . The dash box portion 6 is formed in a substantially box shape having a hollow space therein, and is supported from below by the dash lower member 5 .

That is, the rear edge 4a of the upper instrument panel 4 is sandwiched between the upper edge 5a of the instrument panel lower member 5 and the lower end 7b of the glass support 7 in the up-down direction, and is joined in a state where three sheets are stacked.

The cowl box portion 6 includes a front side box portion 6c and a rear side box portion 6d.

Among them, the front side box portion 6c has a cowl top cover 10 which extends in the vehicle width direction and has a hollow cross-section inside.

The cowl top cover 10 mainly includes: a front wall portion 11 extending in the vehicle width direction; an upper wall portion 12 extending rearward from an upper end portion 11 a of the front wall portion 11 ; The lower wall portion 13 of the descending inclined surface has a hollow cross-section whose cross-sectional shape in the vehicle front-rear direction is substantially U-shaped.

Further, the upper wall portion 12 has an inclination that descends from the front end portion 12a toward the rear of the vehicle. The upper wall portion 12 is integrally provided with a connecting portion 12c via the second bending portion 12b.

The rear end of the connection portion 12c is connected to the front end 3a of the glass panel 3 through a concave engagement groove portion.

In addition, the front wall portion 11 is extended with the out-of-plane direction facing the vehicle front-rear direction. In addition, the lower wall portion 13 and the upper wall portion 12 are arranged at a predetermined interval in the up-down direction. The lower end of the lower wall portion 13 is connected to the front end 4b of the upper instrument panel 4 .

Moreover, the rear side case part 6d is surrounded by the upper instrument panel member 4, the glass support 7, and a part of the front-end|tip 3a side of the glass panel 3, and has a hollow cross section.

Furthermore, the inner space of the front side box portion 6c and the inner space of the rear side box portion 6d communicate with each other in the vehicle front-rear direction, and the inner space of the cowl box portion 6 is formed.

Among them, the upper end portion 11a of the front wall portion 11 and the front end portion 12a of the upper wall portion 12 constituting the front side box portion 6c are connected to form the protruding corner portion 9 .

Accordingly, the protruding corner portion 9 of the present embodiment is located at the uppermost part of the cowl box portion 6 in the vehicle vertical direction, and is provided on the front side in the front-rear direction and at a position covered above the rear end 2a of the hood panel 2 .

As shown in FIG. 3 , at both end portions of the front side box portion 6c, side wall portions that are continuous with the front wall portion 11, the upper wall portion 12, and the lower wall portion 13 are provided on the outer side of the protruding corner portion 9 in the vehicle width direction, respectively. 8.

The side wall portion 8 is formed in a ring shape having a substantially trapezoidal shape in plan view by a plate-shaped member extending from a flat single plane in the vehicle front-rear direction.

That is, the substantially trapezoidal opening part 14 which communicates in the vehicle width direction is formed in the center position in the surface of the side wall part 8. As shown in FIG. The side wall portion 8 has four straight portions 18 extending along each side of the peripheral edge of the opening portion 14 , and four curved portions 20 located at four corners where the straight portions 18 intersect and connecting the straight portions 18 to each other.

Further, the outer peripheral edge 15 of the side wall portion 8 is connected along the respective outer end portions of the front wall portion 11 , the protruding corner portion 9 , and the upper wall portion 12 of the cowl top cover 10 . And the outer peripheral edge 15 of the side wall part 8 is connected so that the surface extending direction is orthogonal to the inner surface of the lower wall part 13 and the connection part 12c.

Further, a sealing surface 17 is formed around the opening portion 14 of the side wall portion 8 .

The sealing surface 17 has a substantially constant dimension W in the width direction between the outer peripheral edge 15 of the side wall portion 8 and the peripheral edge of the opening portion 14 , and is continuously formed in an annular shape along each of the linear portion 18 and the curved portion 20 .

In addition, in the cowl top structure of the present embodiment, the ribs 8a to 8d are respectively protruded from the seal surface 17 of the side wall portion 8 radially outward at a predetermined height toward the vehicle width direction outer side. The ribs 8 a to 8 d correspond to the curved portions 20 , and are provided to protrude from the vehicle outer side surface of the side wall portion 8 .

In addition, a flexible gasket 50 is provided so as to close the opening 14 .

In addition, the washer 50 on the left side of the vehicle among the pair of washers 50 arranged at the left and right end portions of the front side case portion 6c will be described here. The gasket provided on the right side of the vehicle is substantially the same as or equal to the gasket 50 on the left side of the vehicle, so the description is omitted.

The gasket 50 has a thick plate-shaped base portion 56 having a substantially trapezoidal shape in plan view and having irregularities in the in-plane direction, and a sealing portion 51 provided on the inner surface in the vehicle width direction of the peripheral edge of the base portion 56 . A thin lip portion 52 is formed on the seal portion 51 .

In the state where the gasket 50 is installed in the opening 14 , the sealing portion 51 is pressed substantially uniformly over the entire circumference of the outer peripheral edge of the opening 14 to make the lip 52 abut against the sealing surface 17 .

Thereby, the lip portion 52 can seal the opening portion 14 so that the outside water and the air (odor) in the engine room E do not intrude into the cowl portion 6 .

In addition, the lip portion 52 is constituted by a flat single plane, and there is no part where the local rigidity becomes high, for example, a rib or the like. Thereby, it is difficult to generate a gap or float on the sealing surface 17 of the present embodiment, and reliable sealing is performed.

Furthermore, the front end of the lip portion 52 is linearly abutted against the sealing surface 17 and sealed. Thereby, even if the dimension W in the width direction of the sealing surface 17 is reduced, the sealing property can be maintained. Thereby, even if the width of the side wall portion 8 is set small, the sealing performance is not impaired. Thereby, the surface rigidity can be reduced. Therefore, when the protruding corner portion 9 described later is deformed, it is possible to reduce the possibility that the side wall portion 8 hinders the deformation.

The washer 50 has claws 53 (refer to FIG. 5 ) that are respectively engaged with the linear portions 18 of the peripheral edge of the opening portion 14 from the out-of-plane direction.

Then, in a state in which the claw portions 53 are engaged with the linear portions 18 and the gasket 50 is attached to the opening portion 14 as shown in FIG. 52 to be clamped.

At this time, the lip portion 52 is pressed by the sealing surface 17 and elastically contacts while being deformed in the out-of-plane direction. Thereby, the distal end of the lip portion 52 abuts against the sealing surface 17 in the out-of-plane direction without a gap, and the sealing between the sealing surface 17 and the lip portion 52 is reliably performed.

However, in each curved portion 20 shown in FIG. 6 , it is difficult to form, for example, the claw portion 53 having a predetermined strength along the arc shape of the curved portion 20 . In addition, if the claw portion 53 and the curved portion 20 are not locked in a good state, they may float from the sealing surface 17, and there is a possibility that a minute gap will be generated. In addition, the claw portions 53 at the four corners are less likely to deform radially inward, and the lip portions 52 corresponding to the positions of the claw portions 53 are also less likely to follow the shape of the curve, thereby reducing the sealing performance.

Therefore, the gasket 50 of the present embodiment is not provided with the claws 53 at the four corners corresponding to the respective curved portions 20 , and instead of these claws 53 , thin elastic contact portions 54 are integrally provided from the base portion 55 .

The elastic contact portion 54 is formed in a thin-walled shape substantially similarly to the lip portion 52 . Further, the elastic contact portion 54 is connected at the distal end so as to integrate the lip portion 52 . Thereby, the gasket 50 can be easily produced.

In addition, during installation, the claw portion 53 of the washer 50 falls radially inward, and the elastic contact portion 54 elastically deforms in the radial direction of the opening portion 14 with the base portion 55 as a fulcrum, thereby facilitating installation.

In addition, the opening 14 is substantially reliably sealed by two types of seals having different contact directions, so that the lip portion 52 is called an out-of-plane direction seal, and the elastic contact portion 54 is called a radial seal.

In addition, when the gasket 50 of the present embodiment is attached to the opening 14 , as shown in FIG. At this time, the elastic contact portions 54 at the four corners are formed in a thin-walled shape. Thereby, even if the claw portion 53 and the elastic contact portion 54 are formed continuously, it does not hinder the movement of the claw portion 53 . Therefore, the gasket 50 can be easily attached to the opening portion 14 .

In a state where the gasket 50 is attached to the opening portion 14 , the lip portion 52 abuts against the sealing surface 17 and seals over the entire circumference.

When the gasket 50 is attached to the opening 14 , as shown in FIG. 6 , the elastic contact portion 54 is pressed and deformed in the radial direction, and the inner peripheral edge of the opening 14 comes into contact with the inner peripheral edge of the opening 14 in the radial direction from the inside to the outside to seal. Thereby, the sealing property is further improved.

In addition, on the inner peripheral edge of the opening portion 14, the claw portion 53 is locked, and the elastic contact portion 54 is in contact therewith. Thereby, the mounting accuracy is well maintained.

In particular, the elastic contact portion 54 abuts against the inner peripheral edge of the opening 14 even at a site such as a corner portion shown in FIG. 6 where it is difficult to form the claw portion 53 , and can perform double sealing together with the lip portion 52 . Then, the lip portion 52 and the elastic contact portion 54 abut against the sealing surface 17 and the inner peripheral edge of the opening portion 14 by sufficient pressing force from different directions, respectively.

Accordingly, by setting the dimension W in the width direction of the side wall portion 8 forming the sealing surface 17 small, the opening portion 14 can be set relatively large. Furthermore, even if the shape of the corner portion makes it difficult to form the claw portion 53, the elastic contact portion 54 can maintain reliable sealing performance.

Therefore, the degree of freedom of the shapes of the straight portions 18 and 18 and the curved portion 20 is increased, and it is possible to reduce the possibility of hindering the desired deformation.

As shown in FIG. 4 , in the state where the gasket 50 is attached to the opening portion 14 , the ribs 8 a to 8 d are formed at the contact portion of the lip portion 52 with the side wall portion 8 and the corner portion with the outer peripheral edge 15 of the side wall portion 8 . between. Each of the ribs 8 a to 8 d is protruded from the vehicle outer side surface of the side wall portion 8 at a predetermined height, and is formed to be curved so as to follow the curved shape of each corner portion of the gasket 50 .

Thereby, the ribs 8a to 8d can be adjacent to the outer edge of each corner portion of the gasket 50 with a small gap.

And the gasket 50 is accommodated in the outer shape range of the outer peripheral edge 15 of the side wall part 8 by the ribs 8a-8d. Thereby, the front end of the lip portion 52 abuts on the entire circumference of the sealing surface 17 and does not protrude outward from the outer peripheral edge 15 .

Therefore, it is difficult for the user's fingers to enter the lower side of the lip portion 52, and the gasket 50 can be prevented from coming off. In addition, the ribs 8 a to 8 d block the water passing through the sealing surface 17 like a dam, and can suppress the intrusion of water into the opening 14 .

In addition, in the present embodiment, as shown in FIG. 2 , a bent portion 40 is formed in a part of the front wall portion 11 . Moreover, the 2nd bending part 12b is formed in a part of the upper wall part 12. As shown in FIG.

Furthermore, as shown in FIG. 7 , the bent portion 40 and the second bent portion 12b overlap with the opening portion 14 in the vehicle front-rear direction L. As shown in FIG.

As shown in FIG. 2 , the bending portion 40 has a substantially U-shaped cross section, and is easily deformed in the bending direction. In addition, the lower wall portion 13 is formed with a third bent portion 13a. In addition, following the deformation in the bending direction of the front wall portion 11 starting at the bending portion 40 , the second bending portion 12 b of the upper wall portion 12 or the third bending portion 13 of the lower wall portion 13 can be easily made. 13a Deformation.

Thereby, when the bending portion 40 is bent, the opening portions 14 arranged in the vehicle front-rear direction L are easily deformed. Therefore, better deformability can be obtained.

Further, as shown in FIG. 7 , a guide portion 22 is provided below the rear end 2 a side of the hood panel 2 and forward of the dash box portion 6 , with the longitudinal direction along the vehicle width direction.

The guide portion 22 has a sealing wall portion 24 and a connecting wall portion 23 that connects the sealing wall portion 24 and the front wall portion 11 . In addition, the guide portion 22 is formed in a substantially U-shaped cross-section in the vehicle front-rear direction with the upper portion open.

The sealing wall portion 24 is positioned forward of the vehicle than the front wall portion 11 , and extends in the vertical direction below the hood panel 2 . A rubber seal 21 is provided on the upper end edge of the sealing wall portion 24 .

The rubber seal 21 is configured to be in contact with the lower surface on the rear end 2 a side of the hood panel 2 .

In addition, a bent portion 40 is provided at the root portion on the front wall portion 11 side of the guide portion 22 . The bent portion 40 integrally connects the front wall portion 11 and the connection wall portion 23, and extends along the vehicle width direction.

In addition, when the impact load applied to the connecting wall portion 23 is transmitted to the front trunk portion 6, the front wall portion 11 can be deformed as a starting point of bending by the bent portion 40 required for forming the guide portion 22. made easy. Thereby, it becomes easy to further ensure desired deformation characteristics.

Furthermore, as shown in FIG. 8 , the folded portion 40 of the cowl top cover 10 is formed thinner than other surrounding portions.

Thereby, the front wall portion 11 and the connecting wall portion 23 can be easily bent with the bent portion 40 as a starting point.

In addition, as shown in FIG. 2, on the back side of the folded portion 40, a notch portion (thinning) 30 (thinning) that forms a groove portion in a substantially V-shaped cross-section is provided at a portion facing the inside of the front side box portion 6c. Refer to Figure 8).

Accordingly, in the bending portion 40, the front wall portion 11 and the connecting wall portion 23 are easily bent from the cutout portion 30 as a starting point, and the deformability is improved.
