Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an air deflector device for a retractable roof of a vehicle.

[Prior Art] To prevent wind from entering the passenger compartment through the roof window when a slide roof that is openably and closably mounted on a roof window that is opened in a roof panel of a vehicle is slid backward. It is known that an air deflector panel is attached to the front side of the roof window.

If the air deflector panel is fixed on the front side of the roof window at a constant inclination angle, wind noise is generated when the vehicle is running at high speed. Therefore, it is necessary to change the inclination angle of the air deflector panel according to the vehicle speed.

Conventionally, in order to change the inclination angle of the air deflector panel according to the vehicle speed, as shown in FIG. 4, the air deflector panel 5 is attached to the front side of the roof window by a hinge mechanism 7 so as to be able to move up and down. . The air deflector panel 5

[Problems to be Solved by the Invention] By the way, in the above-mentioned conventional device, the spring member 16 '
If the spring constant of is too large, in the low speed range of the vehicle,
When the air deflector panel 5 is set to a desired inclination angle, the air deflector panel 5 receives the elastic force of the spring member 16 'and is lowered to the desired inclination angle in a high speed region of the vehicle. However, wind noise may occur.

Further, if the spring constant of the spring member 16 'is made smaller, the air deflector panel 5 becomes smaller than the desired inclination angle in the high speed range of the vehicle, causing a problem that wind enters the passenger compartment from the roof window. . Therefore, it is necessary to manufacture a large number of spring members having different spring characteristics, assemble the spring members into an air deflector device, and repeat actual traveling before setting the spring members. There was a problem that required labor and time.

In view of the above conventional problems, an object of the present invention is to provide an air deflector device capable of setting the spring characteristics of a spring member in two stages corresponding to a low speed region and a high speed region of a vehicle.

[Means for Solving the Problems] In order to achieve the above object, the present invention is directed to a case where a slide roof that is openably and closably attached to a roof window that is opened in a roof panel of a vehicle is slid backward and opened. An air deflector device for projecting an air deflector panel at a predetermined inclination angle by a deflector arm and a spring member on the front side of the roof window, wherein the base portion of the air deflector panel is the roof. A hinge mechanism is mounted on the front side of the window so as to be able to be tilted, and the base of the deflector arm is tiltably supported by the sunroof housing inside the roof panel.
A tip portion is coupled to the air deflector panel by a pin and an elongated hole, the spring member has a base portion fixed to a sunroof housing, and a tip portion having a first action point which is always in contact with the deflector arm, Further, the spring member is provided with a second action point facing the deflector arm so that it can come into contact with and separate from the deflector arm between a first action point at the tip of the spring member and a base portion of the spring member. Is.

[Operation] In the air deflector device configured as described above, the spring member is provided with the first and second action points, and
The spring constant of the spring member when a load acts only on the point of action is set corresponding to the low speed range of the vehicle, and the spring constant when the load acts on the second point of action corresponds to the high speed range of the vehicle. By setting the spring constant, when the vehicle speed is low, the air deflector arm is held at a predetermined inclination angle with only the first action point of the spring member being in contact with the deflector arm.

When the vehicle is moving at high speed, the air deflector panel tilts when the member deflected by the deflector arm is deflected by the wind pressure applied to the air deflector panel and the arm contacts the second action point of the spring member. Can be stopped.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 3, a roof window 2 is provided on a roof panel 1 of the vehicle.
Is opened, and the sunroof housing 3 is provided inside the roof panel 1 along the opening edge of the roof window 2.
Is assembled. A slide roof 4 for opening and closing the roof window 2 is slidably mounted on the sunroof housing 3.

The air deflector device in the openable roof is mainly composed of an air deflector panel 5, a deflector arm 6 and a spring member 16.

That is, as shown in the first part, on the front side of the window of the roof 2, the hinge bracket 8 is attached to the upper surface of the sunroof housing 3, while the hinge arm 9 is attached to the lower front part of the air deflector panel 5. It is fixed in the section. And the air deflector panel 5 is
The other end of the hinge arm 9 is attached to the upper portion of the hinge bracket 8 by the hinge pin 10 so that the hinge arm 9 can be erected in the air deflector position and the retracted position.

On the upper surface of the sunroof housing 3, a base 11 is mounted at a predetermined distance from the hinge bracket 8 toward the rear of the vehicle. At the rear end portion, the pin 13 is tiltably attached to the fulcrum. The front end of the deflector arm 6 has an air deflector panel 5
Of the arm 6 is connected to the tip of the air deflector panel 5 by a pin 14 and an elongated hole 15.

On the upper surface of the base 11, the spring member 16 is provided with a base portion 16a.
Is stuck in. The spring member 16 is formed by bending a flat strip-shaped spring plate material into a substantially S shape, and the tip end thereof is always in contact with the lower surface of the deflector arm 6 as a first action point 17. . Further, in the spring member 16, between the first action point 17 and the base portion 16a, a portion bent toward the lower surface of the deflector arm 6 in a projecting shape is used as a second action point 18, and It opposes the lower surface of the tractor arm 6 so that it can come into contact with and separate from it. That is, the spring member 16 is configured to have a small spring constant when a load acts only on the first action point 17 at the tip thereof and a large spring constant when a load acts on the second action point 18. Further, the first action point 17 of the spring member 16 is set at a position higher than the second action point 18.

This embodiment is constructed as described above. Therefore,
When the sliding roof 4 is slid rearward to open the roof window 2, as shown in FIG. 1, the air deflector panel 5 is inclined to a predetermined angle via the deflector arm 6 by the elastic force of the spring member 16. Projected at an angle.

When the vehicle is stopped or running at a low speed, as shown by the solid line in FIG.
When only 17 is in contact with the deflector arm 6 and the second action point 18 is separated, the air deflector panel 5 is held at a relatively large inclination angle. Therefore, when the vehicle is running at low speed, the air deflector panel 5 prevents wind from entering the vehicle interior as much as possible.

When the vehicle is at high speed, the spring member 16 is deflected by a predetermined amount as shown by the chain line in FIG. 1 by the wind pressure applied to the air deflector panel 5, and its second action point 18 is in contact with the deflector arm 6. By the way, the deflector arm 6 is supported. Therefore, the air deflector panel 5
Can be held at a desired inclination angle suitable for high speed, and wind noise can be reduced.

When the sliding roof 4 is slid forward and the roof window 2 is closed, as shown in FIG.
The pressing roller 19 protruding from the lower surface is used for the deflector arm 6
By sliding on the upper surface of the air deflector 6 together with the deflector arm 6 against the elastic force of the spring member 16.
