Description

[Detailed Description of the Invention] The present invention relates to an air intake structure from a cowl top grill of a vehicle.

Examples of conventional air intake structures of this type include those shown in FIGS. 1 and 2.

Reference numeral 1 denotes a cowl top grill, in which a number of slits 2 are opened and a drip part 3 is formed at the front end.

A dash upper panel 4 consisting of a rear vertical plate 4a, a bottom plate 4b, and a front vertical plate 4C is disposed below the cowl top 1.

What is the cowl top grill 1 and the dash upper panel 4?
They are joined to each other at their rear ends to form a generally box-like shape as a whole.

A side vent 5 equipped with a water-shielding plate 5a is provided on the rear vertical plate 4a of the dash upper panel 4, and a side vent 5 is provided on the rear vertical plate 4a of the dash upper panel 4.
An intake hole 7 communicating with the air conditioner 6 etc. is provided in b.

A water shielding plate 8 is welded and supported at its rear end to the rear vertical plate 4a to cover the upper part of the intake hole 7 and prevent rainwater from entering the intake 7.

Reference numeral 9 denotes a hood, which is disposed with a gap 10 between it and the drip portion 3 of the cowl top grille 1.

11 is a weather strip, 12 is a windshield, 1
3 is a weather strip, which is attached to the cowl top grill 1.
Then, the rear end of the dash upper panel 4 and the lower end of the fluorocarbon glass 12 are connected airtightly and watertightly.

In this air intake structure, air is taken into the lower part of the cowl top grille 1 through the gap 10 between the slits 2 and the air is sent into the air conditioner 6 etc. through the intake hole 7, and the air is sent into the air conditioner 6 etc. through the side vent 5. into the passenger compartment via the

However, in the conventional air intake structure, which is very crowded, due to design constraints and constraints to prevent water from entering the passenger compartment from the intake hole 7 and side vent 5. There are restrictions on the dimensions J and number of the slits 2 (noted separately), and air introduction from the gap 10 is limited.
Since the front and rear portions are labyrinth-shaped, ventilation resistance becomes large, and there is a problem in that the amount of air taken into the lower part of the cowl top grille 1 is not sufficient.

Therefore, in order to compensate for this lack of air volume, the size of the blower fan of the air conditioner 6 etc. has been increased, but according to this, the noise due to the increase in intake sound of the blower fan has been increased. This results in an increase in air flow and cost, and also causes a problem in that the feeling of cool breeze decreases due to insufficient amount of air entering the vehicle interior from the air vents 5.

The present invention was developed by focusing on these conventional problems.In addition to opening an air supply hole in the drip part of the cowl top grille, the present invention also includes a water-shielding system that forms a closed-section duct in the upper dash panel. The plates are combined, and the air flowing in from the slit of the cowl top grille and the air supply hole is transferred to the water-shielding plate through a vent opening that is offset from the intake hole, or a duct through the end opening of the duct. The aim is to solve the above problems by incorporating this into the system.

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

3 and 4 are diagrams showing an embodiment of the present invention.

First, to explain the structure, this air intake structure can be roughly divided into a dash upper panel 4, a water shield plate 8, and a cowl top grille 1, as shown exploded in FIG.

As shown in FIG. 4, the cowl top grill 1 extends from the lower end of the windshield 12 of the vehicle to the front of the vehicle (in the direction of arrow F).
It has a large number of slits 2 for distributing air downward, and a drip part 3 at the front end.

The rear vertical plate 3a and bottom part 3b of the drip part 3 are provided with an air supply hole 14 for distributing air downward, similar to the louver 2, so that the louver 2 and the air supply hole 14 are connected to each other. air is taken in downwards.

The dash upper panel 4 is composed of a rear vertical plate 4a, a bottom plate 4b, and a front vertical plate 4C, and the upper end of the rear vertical plate 4a is connected to the rear ends of the cowl top grille 1 and the water shielding plate 8. .

Further, a side vent 5 is provided on the rear vertical plate 4a, and a side ventilator duct 5a is connected to this.

An intake hole 7 is formed in the bottom plate 4b, and an air conditioner 6 is connected to the intake hole 7.

A frame 7a is provided around the intake hole 7, and the bottom plate 4
This prevents rainwater above b from flowing into the intake hole 7.

The water dispensing plate 8 has its rear end connected to the rear end of the cowl top grill 1 and the upper end of the rear vertical plate 4a of the dash upper panel 4, and its front end connected to the bottom plate 4b of the dash upper panel 4, as described above. They are combined to form a duct 15 that covers the intake hole 7 above.

The duct 15 has a closed section surrounded by the rear vertical plate 4a of the dash upper panel 4, the bottom plate 4b, and the water shielding plate 8.

The water shielding plate 8, like the cowl top grille 1 and the dash upper panel 4, extends in the width direction of the vehicle to the cowl side inner panel 16, and this closed section is also used as a reinforcing member.

The water shielding plate 8 near the intake hole 7 bulges forward to form a bulge 8a.
and a vent 8 located offset from the side vent 5.
b is opened, and the front and rear of the water shielding plate 8 are communicated through the ventilation hole 8b.

Note that the water shielding plate 8 has the slit 2 and the air supply hole 1.
Since it is sufficient to prevent rainwater entering through the intake hole 7 from entering the intake hole 7, the water plate 8 is made long enough to cover the intake hole 7 and its vicinity, and therefore the length of the duct 15 is shortened to prevent the water from entering the intake hole 7. Air may be introduced into the duct 15 from an opening at the end of the duct 15 instead of 8b.

Although not shown, the dash upper panel 4 is provided with a drainage structure so that rainwater on the bottom plate 4b can be removed.

Reference numeral 9 denotes a hood, and 11 a weather strip, which maintains watertightness between the front vertical plate 4C of the dash upper panel 4 and the hood 9.

12 is a windshield, and 13 is a weather strip.

Next, the effect will be explained.

Air from the outside enters under the cowl top grille 1 through the slits 2 and the air supply holes 14.

Air supply hole 14. are the rear vertical plate 3a and the bottom plate 3 of the drip part 3.
Since there is an opening at b, the air entering from here enters smoothly and sufficiently because there is little ventilation resistance.

Therefore, the shortage of air entering through the slits 2 caused by the size and number of the slits 2 which are restricted in design is compensated for by the air entering through the air supply holes 14.
Make up for it in minutes.

Therefore, a sufficient amount of air that has entered under the cowl top grille 1 enters the duct 15 having a closed cross section through the ventilation hole 8b of the water shielding plate 8, and from there passes through the intake hole 7 to the air conditioner. 6 etc., and is also introduced into the passenger compartment via the side vent 5 and side ventilator duct 5a.

Rainwater when driving in the rain or washing the car enters under the cowl top grille 1 through the slit 2 and the air supply hole 14.

A part of it enters the duct 15 through the vent 8b and falls onto the bottom plate 4b inside the duct 15, and a part of it hits the surface of the water-shielding plate 8 and hits the bottom plate before the water-shielding plate 8. 4b, and the remainder falls directly onto the bottom plate 4b in front of the water shielding plate 8.

In this way, the rainwater that entered the dash upper panel 4
are all gathered on the bottom plate 4b, and a drainage structure (not shown) is provided on the side of the bottom plate 4b.

) is drained from the water.

At this time, the intake hole 7 and the side vent 5 are offset from each other, and the water shielding plate 8 is connected to the bottom plate 4b, so that the rainwater that has entered under the cowl top grille 1 can be removed from the ventilation hole 8b. However, it does not enter into the intake hole 7 and the side vent 5 directly or indirectly by hitting the bottom plate 4b and rebounding.

As explained above, according to the present invention, the configuration is such that the air supply hole is opened in the drip part of the cowl top grill,
In addition, a water-shielding plate is hung between the vertical plate and the bottom plate of the dash upper panel to form a duct with a closed section, and air is also drawn into the intake hole, etc. from the ventilation hole of the water-shielding plate or the opening at the end of the duct. As a result, the amount of air that is insufficient to be taken in from the slit in the dash upper panel is
The air can be taken in from the air supply hole and sufficiently supplemented.

Therefore, a sufficient amount of air can be introduced into the air conditioner or the room through the intake hole, etc., so it is possible to reduce the noise and cost by reducing the size of the blower fan, and also to By providing a large amount of air, it is possible to improve the feeling of cool breeze.

In addition, rainwater that has entered the cowl top grill is prevented from entering the intake holes, etc., either directly or indirectly by bouncing back, and is therefore completely drained from the bottom plate of the dash upper panel through the drainage section.

Therefore, it is possible to prevent rainwater from entering the air conditioner or the vehicle interior through the intake hole or the like.
