DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air flow control device for a vehicle capable of simultaneously introducing outside air into a vehicle interior and rectifying traveling wind around a lower portion of a windshield.

[0002]

2. Description of the Related Art Generally, in a car, a front deck is provided with an outside air introduction port into a vehicle interior. In order to efficiently introduce the traveling wind into the vehicle interior, it is desirable that the introduction port be open toward the front side of the vehicle. However, in a general passenger car, an opening as an outside air introduction portion is provided at the rear end of the bonnet in front of the front window glass, and the traveling wind flowing on the hood hits the front window glass, and the front deck is pushed through the opening. Through the vehicle interior.

In such an automobile, it is necessary to set a large opening area for introducing outside air, and it is also necessary to apply a traveling wind to the front window to flow the wind downward, so that the air resistance becomes large. They also increase the size and degrade the appearance, and are accompanied by many design constraints.

Therefore, as shown in Japanese Utility Model Laid-Open Publication No. 64-32211, an air intake structure has been proposed in which the lower edge of the air intake is located below the engine hood to reduce the amount of upward projection. Also, Japanese Patent Laid-Open No. 4-8
As shown in No. 1321, an outside air introduction structure including a guide member for deflecting traveling wind toward the outside air introduction port side has been proposed. In the case of such a structure, outside air can be introduced into the vehicle interior without setting the opening area larger than necessary.

[0005]

In the structure using the conventional air intake, the outside air can be introduced into the vehicle interior without increasing the opening area of the inlet. However, the outside air flows around the upper part of the air intake. A turbulent flow, such as a state in which the sheet is once peeled off from the windshield and rolled down again, occurs. This increases noise and air resistance,
There was a problem that dust and the like adhered to the windshield.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to introduce outside air into a vehicle interior without using an air intake, and to simultaneously achieve rectification of traveling wind around a lower portion of a windshield. It is an object to provide a control device.

[0007]

According to the present invention, there is provided a vehicle comprising: a windshield of a vehicle; a vehicle body member extending from below the windshield toward the front of the vehicle; An external air introduction port provided to extend in the vehicle width direction between the vehicle body member and a front deflector attached to the vehicle body member and formed to extend in the vehicle width direction; The traveling wind flowing on the upper surface of the vehicle body member at the time of traveling of the vehicle is branched to the windshield side and the outside air inlet side, and from a branch portion disposed above and outside the vehicle of the outside air inlet, from the branch portion. A straightening portion that extends upward and rearward of the vehicle and guides the traveling wind toward the windshield, from the branch portion. Extending towards both lower and rear, and having a guide portion for guiding the running wind into the outside air introduction port.

[0008]

[Function] The airflow flowing over the hood by the guide section
At the same time it is leading to the passenger compartment, to rectify the airflow to the front window glass upper by the rectifying unit.

[0009]

1 is an external view of a vehicle provided with an airflow control device for a vehicle according to an embodiment of the present invention, and FIG.
The view from the arrow II is shown.

As shown in FIG. 1, an outside air inlet 4 is formed between a bonnet 2 and a front window 3 of an automobile (vehicle) 1, and the outside air inlet 4 is open on the upper surface side. A front deflector 5 is provided at the outside air inlet 4, and the front deflector 5 is provided to extend in the vehicle width direction of the vehicle 1.

As shown in FIG. 2, the front deflector 5
Is attached to the rear end of the hood 2. The front deflector 5 includes a guide portion 6 extending downward so as to guide the airflow A flowing on the hood 2 during traveling of the vehicle into the vehicle interior ,
A rectifying section 7 extending upward along the front window 3 so as to guide the airflow B to an upper portion of the front window 3 is formed. The guide section 6 and the rectifying section 7 are formed integrally. The branch portion 8 of the guide portion 6 and the rectifying portion 7 is connected to the outside air inlet 4.
Is slightly higher than the rear edge of the hood 2 (hood outer hemming portion), which is the front edge of the opening, and there is a slight gap in the vehicle height direction between the branch portion 8 and the rear edge of the hood 2. It has become.

During traveling of the vehicle, the airflow A flowing on the hood 2 is guided by the guide portion 6 of the front deflector 5 and is introduced into the vehicle interior from the outside air inlet 4. At this time, since there is only a slight gap between the branch portion 8 and the rear edge of the bonnet 2, the flow velocity of the airflow A is increased, the outside air introduction pressure is increased, and the outside air is introduced efficiently. During traveling of the vehicle, the airflow B flowing on the hood 2 is rectified by the rectification unit 7 of the front deflector 5 and guided along the front window 3 to prevent turbulence.

Therefore, by using the front deflector 5 described above, the vehicle can be used without using an air intake.
The outside air can be efficiently introduced into the room , the rectification of the lower portion of the front window 3 can be performed, and the effect of reducing the air resistance can be exhibited. In addition, the amount of upward projection of the bonnet 2 is only the amount of clearance between the branch portion 8 and the rear edge of the bonnet 2, so that the appearance is not impaired.
Since the lower portion of the front window 3 is covered with the front deflector 5, the appearance is further improved. Also, since the front deflector 5 can be easily attached and detached, the vehicle 1
Mounting and replacement can be easily performed.

FIGS. 3 to 5 show a case where the above-described front deflector 5 is mounted on vehicles of different types.

In FIG. 3, the rear edge of the bonnet 2 is located immediately above the lower end of the front window 3, and the lower portion of the rear edge of the bonnet 2 is the outside air inlet 4. The front deflector 5 is provided behind the rear edge of the hood 2, and the branch portion 8 is set slightly above the rear edge of the hood 2. 3, the introduction of outside air into the vehicle interior and the rectification of the traveling wind around the lower part of the front window 3 can be simultaneously achieved by the front deflector 5 as described above.

FIG. 4 shows a garnish 11 which supports a lower end of a front window 3 with a front deflector 5 attached thereto. The outside air inlet 4 is open on the upper surface side. The front deflector 5 is located on the rear end side of the outside air inlet 4, and the branch portion 8 is set slightly above the rear end edge of the bonnet 2. 4, the introduction of outside air into the vehicle interior and the rectification of the traveling wind around the lower part of the front window 3 can be simultaneously achieved by the front deflector 5 as described above.

[0017]

The airflow control device for a vehicle according to the present invention controls the airflow.
Since it is composed of a guide section that guides the passenger compartment and a rectifying section that guides the airflow to the upper part of the windshield, outside air can be introduced into the passenger compartment without using an air intake. Rectification can be achieved. As a result, it is possible to simultaneously reduce the air resistance and improve the outside air introduction efficiency. In addition, since the amount of protrusion above the hood may be small, the appearance is not impaired, and the lower part of the window glass is covered, so that the appearance is further improved. Further, since the airflow control device of the vehicle can be easily attached and detached, it can be easily mounted and exchanged on the vehicle.
