Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the baffle structure of a cowl ventilation device for an automobile.

Conventionally, automobile cowl ventilation devices include:
As shown in FIGS. 1 and 2, a ventilation air introduction slit 4 is formed in the cowl grille 3 between the bonnet 1 and the front window 2, and a cowl panel 5 and grille are formed inside the vehicle body. A horizontal wall 7 whose front edge is fixed to the lower part of the cowl panel 6, and a vertical wall 7 whose upper edge is fixed to the lower surface of the front window adhesive surface of the cowl panel 5, which rises upward from the rear edge of the horizontal wall 7. A dash panel top 9 having a wall 8 is provided to form a closed cross section, an opening 7a is formed in the horizontal wall 7 of the dash panel top 9, and an outside air introduction hole 10 for air conditioning is formed at the periphery of the opening 7a. At the same time, an opening Ba is formed in the vertical wall 8 near the outside air introduction hole 10, and a duct 13 forming the outside air introduction hole 12 for ventilation of the vehicle interior is inserted into the opening Ba. What has been developed has been put into practical use.

However, in the conventional cowl ventilation device described above, the baffle plate 11 prevents rainwater etc. accumulated on the horizontal wall 7 of the dash panel upper 9 from entering the outside air introduction hole 10, but for example, When parking on a slope, rainwater does not flow into the drainage channel 14 and accumulates as shown by the two-dot chain line in the figure, causing the water level L to rise.
There was a problem with 2 entering the vehicle interior.

In addition, since both the outside air introduction holes 10 and 12 need to be provided at nearby positions in relation to other devices, the baffle plate 1
1, the effective passage area S of the outside air introduction hole 12 decreases,
Furthermore, a large opening 7a, Ba
There was also the problem that the rigidity decreased because two of them were provided.

The present invention has been made in view of the above-mentioned conventional problems.
Encompassing both outside air intake holes of the darts panel atspa,
A peripheral side wall forming an opening upward is provided, a continuous flange is formed at the lower end and rear end of the peripheral side wall, the flange at the lower end of the peripheral side wall is connected to the horizontal wall surface of the dash panel top, and the flange at the lower end of the peripheral side wall is connected to the vertical wall surface of the dash panel upper. The flanges at the rear ends of the side walls are each continuously and watertightly fixed to prevent rainwater from entering, secure an effective passage area, and improve the rigidity of the dash panel top. Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Note that parts having the same configuration and function as those of the above-mentioned conventional example are given the same numbers, and explanations thereof will be omitted.

As shown in FIGS. 3 and 4, an outside air introduction hole 15 for air conditioning is bored in the horizontal wall 7 of the dash panel top 9, and a urethane or rubber material is inserted into the outside air introduction hole 15 from below the horizontal wall 7. The duct 17 is communicated through a seal 16 such as the like.

On the other hand, the baffle plate 18 has a horizontal wall on both sides of both the outside air introduction holes 12 and 15, with respect to the outside air introduction hole 15 and the outside air introduction hole 12 provided in the vertical wall 8 near the outside air introduction hole 15. 7 to a vertical wall 8 slightly above the outside air introduction hole 12
one side extending along the vertical wall 8 and the outside air introduction hole 15 from the vertical wall 8
A substantially triangular or triangular shape with one side extending along the horizontal wall 7 to a point slightly in front of the outside air introduction hole 15, the other side extending along the horizontal wall 7 from the vertical wall 8 to a point slightly in front of the outside air introduction hole 15, and an oblique side connecting these two sides. A pair of trapezoidal side walls 19, 19 are arranged, the top side is closed with a front wall 20, and the oblique side is closed with a diagonal wall 22 having an opening 21, thereby providing a peripheral side wall 23 closed on four sides. The lower and rear ends of the peripheral side wall 23 include an outwardly facing.
a flange 24 is provided, the flange 24 at the lower end of the peripheral side wall 23 extends over the horizontal wall 7 of the dash panel upper 9, and the flange 24 at the rear end of the peripheral side wall 23 extends over the vertical wall 8 of the dash panel upper 9; Continuously and watertightly fix by welding, etc.

However, if the baffle plate 18 has the above configuration,
Since both the outside air introduction holes 12 and 15 are surrounded by the surrounding side wall 23, the side walls 19 and 19 prevent rainwater and the like from entering the vehicle interior through the outside air introduction hole 12 even when parking on a slope.
Moreover, the effective passage area S of both the outside air introduction holes 12 and 15 is sufficiently secured by the opening 21 of the surrounding side wall 233. Furthermore, since the horizontal wall 7 and the vertical wall 8 are reinforced by the so-called box-shaped structure of the baffle plate 18, the cross-section 4. There is no decrease in the rigidity of the U-Panel Atsupah 9, and rather the rigidity is improved. In the baffle plate 18 having the above configuration, as shown in FIG. ,
By welding the baffle plate 18 so that it faces the flange 24, the rigidity of the baffle plate 18 is further increased. 26b, the reinforcing member 29 of the steering bracket 28 is also reinforced, reducing steering wheel vibration during high-speed driving.

As is clear from the above description, the present invention provides a baffle whose flange is watertightly fixed to the dash panel top, with both outside air introduction holes of the dash panel top being surrounded by surrounding side walls. Since it is a plate, even if rainwater or the like accumulates on the horizontal wall of the dash panel top when parking on a slope, the surrounding side walls prevent the rainwater or the like from entering the vehicle interior through the outside air introduction hole in the vertical wall. In addition, unlike the conventional baffle plate described above, the baffle plate does not reduce the effective passage area of the outside air introduction hole in the vertical wall, and furthermore, since the vertical wall and the horizontal wall are reinforced as a box-shaped structure, both the outside air The rigidity of the dash panel upper is improved despite the presence of the introduction hole.
