Abstract

PURPOSE:To prevent entrance of rainwater into a hood ledge reinforcement and improve collision resisting properties, by covering a draining recess with a cover plate mounted to the lower part of the hood ledge reinforcement. CONSTITUTION:An end part 23, on a front fender panel 16 side, of a cover plate 21 is bent downward to form a turned-downward bent part 24, and thus, an opening 25 of a tunnel 22 is not positioned facing an inner surface 17 of the front fender panel 16 but turned downward. If, in the bent part 24, the opening 25 of the tunnel 22 is located facing the inner surface 17 of the front fender panel 16, in case undercoating is made by an electrodeposition painting, an electrodeposition liquid gathering in a cowl part 1 flies directly to the inner surface 17 of the front fender panel 16 through the opening 25, and a coating film is hardly formed. Therefore, the opening 25 is turned downward, and this improves coating of the electrodeposition liquid on the inner surface 17 of the front fender panel 16.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle cowl structure in which a hood ridge reinforcement is passed through.

2. Description of the Related Art Conventional vehicle cowl structures include those shown in FIGS. 1 to 4, for example. In the figure, reference numeral 1 denotes a cowl portion, and the cowl portion 1 is formed into a box shape by joining a dash upper panel 2 and a cowl top panel 3. In addition, an outside air introduction hole 4 to an air conditioner (not shown) is formed in the evening cover panel 2, and the cowl top panel 3
An outside air intake hole 5 is formed in the. Furthermore, hood ridge reinforcements 7a and 7b extending in the front-rear direction extend through both ends 6 of the cowl portion 10 in the vehicle width direction (direction into the figure) at both upper sides of the engine room. The upper parts 8 of the hood ridge reinforcements 7a and 7b are joined together, the lower parts 9 are left open and are joined to the dash upper panel 2, and the rear end part 10 is connected to the front. It is in a state where it is joined to the pillar 11. Also.

A strut housing 12 that supports a suspension (not shown) is joined to the center of the hood ridge reinforcements 7a, 7b.

A recess 14 for draining water is provided at both ends 13 of the dash upper panel 2, and the opening 15 of the recess 14 faces the inner surface 17 of the front fender panel 16. Rainwater that has entered the cowl part 1 from the outside air intake hole 5 of the cowl top panel 3 is made to flow out from the four water drainage parts 14 into the inner space of the front fender panel 16 and discharged from there to the outside of the vehicle. There is.

However, in such a conventional vehicle cowl structure, the water drainage recess 14 formed in the dash upper panel 2 communicates with the inside of the hood ridge reinforcements 7a and 7b, so that the cowl When the amount of rainwater that has entered the portion 1 is small, this is not a particular problem, but if the amount of water increases and overflows in the drainage recess 14, the rainwater will leak from the recess 14 into the rainwater reinforcements 7a and 7b. There is a risk that rainwater may enter the structure and cause rust, reducing its function as a structural member.

Also, rainwater is leaking onto the dash upper panel 2 in the engine compartment 1.
Although a rising portion may be considered to prevent rust from entering the 8 side, there is a problem in that this method cannot sufficiently prevent rust from occurring. Furthermore, in the VC, the hood ridge reinforcement, which extends in the front-rear direction as a closed cross-section structural member, becomes an open cross section at the position corresponding to the fourth part 14, so in the event of a collision, the hood ridge reinforcement breaks due to lack of rigidity in this part, and the collision energy is There was also the problem that it was not able to absorb enough water.

This invention was made by focusing on such conventional problems, and can reliably prevent rainwater from entering into the hood ridge reinforcement, reliably prevent the occurrence of rust, and further improve collision resistance. It is an object of the present invention to provide a cowl structure for a vehicle that can also improve the performance.

Specifically, the present invention has a structure in which a hood ridge reinforcement is passed through both ends in the vehicle width direction of a cowl portion formed by joining a dash upper panel and a cowl top panel, and a hood ridge reinforcement is provided at both ends of the dash upper panel. The above object is achieved by providing a cover plate below the hood ridge reinforcement at a position corresponding to the recess of the hood ridge to cover the recess for draining water.

The present invention will be explained below based on the drawings.

Incidentally, in the following, parts common to those in the prior art are designated by common reference numerals, and redundant explanation will be omitted.

FIGS. 5 to 7 are diagrams showing an embodiment of the present invention. That is, the hood ridge reinforcement 7a is located at a position corresponding to the water drainage recesses 14 formed at both ends 13 of the dash upper panel 2.

A recess 20 is provided above the lower part 9VC of 7b to form the recess 1.
I am trying to expand the space above 4.

Then, a cover plate 21 having a substantially semi-cylindrical shape corresponding to the shape of the recess 20 is provided in the recess 20, and the recess 1 for draining water is provided.
4, and a tunnel 22 is formed by the cover plate 21 and the concave portion 14 for draining water. Therefore. tunnel 2
2, since the opening area becomes larger, the drainage performance inside the cowl part 1 improves, and -! Since the covered plate 21 shields the inside of the cowl portion 1 and the inside of the hood ridge reinforcements 7a, 7b, the hood ridge reinforcements 7a, 7
By preventing rainwater from entering b, rust is also prevented, and furthermore, since the cover plate 21 reinforces the open cross-section hood ridge reinforcements 7a and 7b, the collision resistance of the cowl portion 1 is also improved. It happens.

FIG. 8 shows another embodiment. In this embodiment, the cover plate 2
A downward bent portion 24 is formed at the end portion 23 on the side of the front fenter panel 16 of the first front fenestration panel 1.

Connect the opening 25 of the tunnel 22 to the front fendant panel 1.
It is arranged to face downward without facing the inner surface 17 of 6. This bent portion 24 is formed by the opening 2 of the l-channel 22.
5 is opposed to the inner surface 11 of the front fender panel 16, the electrodeposition liquid accumulated in the cowl part 1 during the undercoating by electrodeposition is transferred from the opening 25 to the front fender panel 1.
Since the electrodepositing liquid directly hits the inner surface 1T of the front fender 6 and is difficult to adhere to, the opening 25 is oriented downward to allow the electrodeposition liquid to adhere well to the inner surface 17 of the front fender tunnel 16. The other configurations and operations are the same as in the previous embodiment, so their explanation will be omitted.

As explained below, according to the present invention.

A cover plate is provided at the bottom of the hood ridge reinforcement, which corresponds to the water drainage recesses at both ends of the cowl as described above, to reliably prevent rainwater from entering the hood ridge reinforcement and prevent rust from forming. Furthermore, since the cover plate also serves as reinforcement, it is possible to improve the collision resistance of the cowl portion. Further, as shown in the embodiments of FIGS. 5 to 7, an upwardly recessed portion may be formed at the bottom of the hood ridge reinforcement.

The opening area becomes smaller and the drainage performance can be improved, and if the configuration is as shown in the embodiment shown in Fig. 8, in addition to the above effects, it is possible to ensure that the paint film is maintained on the inner surface of the front fender panel when electrodeposited undercoat is applied. It has the effect of being able to be attached to.
