Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention mainly relates to an air spoiler mounting structure for attaching an air spoiler to a vehicle body for changing the airflow at the rear of the vehicle body.

[Background technology]

The rear spoiler is located at the rear end of the luggage door at the rear of the vehicle.
It is attached to the rear end of a hatch door with a mounting bolt to improve the aerodynamic characteristics of the rear of the vehicle.

Among these rear spoilers, wing type rear spoilers are made of hard synthetic resin to improve rigidity and are relatively heavy. For this reason, a large external force is applied to the luggage door from the rear spoiler when the luggage door is closed. In particular, when the luggage door is closed, the impact causes a rotational moment to act on the rear spoiler around the mounting bolts.
As the rear spoiler moves away from the mounting bolts in the longitudinal direction of the vehicle body, a large external force is applied to the luggage door from the rear spoiler.
In some cases, it was necessary to change the shape of the mounting part.

[Purpose of invention]

The present invention takes the above facts into consideration and aims to provide an air spoiler mounting structure that can effectively alleviate the external force applied from the air spoiler to a vehicle body such as a luggage door.

[Summary of the idea]

In the air spoiler mounting structure according to the present invention, a protector that is more flexible than the spoiler body is interposed between the spoiler body and the vehicle body for buffering purposes, and is designed to alleviate external force applied to the vehicle body from the air spoiler. In particular, the thickness of the protector is gradually increased as it moves away from the screw means in the longitudinal direction of the vehicle body, so that the external force applied to the vehicle body from the air spoiler can be effectively alleviated without making the protector thicker than necessary.

[Example of idea]

FIG. 1 shows an embodiment in which the air spoiler attachment structure according to the present invention is applied to attaching a rear spoiler to a body.

In this embodiment, an air spoiler 10 is attached to a luggage door 14 for closing a rear luggage compartment of a body 12.

The air spoiler 10 has an air spoiler main body 16 and a protector 18, as shown in FIG. The air spoiler main body 16 is integrally molded in the shape of a hard urethane foam coated with F.R.P, and a wing portion 16B is connected to the top of the support portion 16A. This wing part 1
6B has a surface that is horizontal or has an angle of attack so that airflow from the body roof is most likely to hit it, thereby reducing air resistance and lift at the rear of the body.

The base of a bolt 20, which is a screw means, is implanted in the lower end surface of the support column 16A. A plurality of bolts 20 are provided at appropriate intervals in the direction perpendicular to the plane of the paper in FIG.

Through holes are formed in the luggage door 14 to correspond to these bolts 20, and nuts (not shown) are tightened from the luggage compartment side to the through heads of these bolts 20 to attach the rear spoiler 10 to the body 12. It is.

The lower end of the air spoiler body 16 on which these bolts 20 are erected is a first bottom surface 16C, and furthermore, the lower end surface of the air spoiler body 16 is formed with a second bottom surface 16D. This second bottom surface 16D has a floating structure that is further away from the luggage door 14 in the attached state than the first bottom surface 16C.

The protector 18 is integrally molded from foamed sponge rubber and is more flexible than the air spoiler main body 16. This protector 18 is connected to the first bottom surface 16C of the air spoiler body 16 and the luggage door 1.
4 and the second bottom surface 16
A thick wall portion sandwiched between D and the luggage door 14 is provided. A through hole 22 for a bolt 20 is bored in the thin wall portion. The thick part gradually becomes thicker towards the rear of the car body. To explain in detail, the thick part of the protector 18 is attached to the luggage door 14.
The protector 1 is tilted with respect to the first bottom surface 16C so that the second bottom surface 16D of the air spoiler main body 16, which is held between the
The thick wall portion 8 gradually becomes thicker toward the rear of the vehicle.

Moreover, this protector 18 is surrounded by a thin wall 24.
is erected and surrounds the vicinity of the bottom of the air spoiler main body 16.

This protector 18 can be easily assembled if it is fixed in advance to the bottom surface of the air spoiler body 16 by adhesive or the like.

In addition, it is preferable that the surface of the protector 18 is a skin surface and has the same painted appearance as the surface of the air spoiler main body 16 so that it does not look strange in terms of design.

In the rear spoiler mounting structure of this embodiment configured as described above, assembly is completed by inserting the bolt 20 into the through hole of the luggage door 14 and tightening the nut from the opposite side. After assembly, the air spoiler 10 is securely fixed to the luggage door 14, so that desired aerodynamic characteristics can be obtained.

When opening and closing the luggage door 14, the protector 18 is interposed between the air spoiler main body 16 and the luggage door 14.
Due to the buffering effect, damage to the luggage door 14 can be prevented, and deformation of the luggage door 14 can be prevented by alleviating the external force applied from the air spoiler 10 to the luggage door 14 when the luggage door 14 is closed. In particular, since the protector 18 gradually becomes thicker as it moves away from the bolt 20 toward the rear of the vehicle body, the external force applied from the air spoiler 10 to the luggage door 14 when the luggage door 14 is closed can be effectively alleviated. That is, when the luggage door 14 is closed, a rotational moment acts on the air spoiler 10 in the clockwise direction in FIG. Depending on the magnitude of this external force, the protector 18 is tightened by the bolt 20.
Since the protector 18 becomes thicker toward the rear of the vehicle body, it is possible to effectively alleviate the external force applied from the air spoiler 10 to the luggage door 14 without making the protector 18 thicker than necessary.

Although the above embodiment shows a structure in which a rear spoiler is attached to a luggage door, the present invention is not limited to the above structure and can be applied to any case in which an air spoiler is attached to a body.

Further, in the above embodiment, the case where the bolt is installed vertically on the air spoiler has been described, but it goes without saying that the present invention can also be applied to the case where a screw means such as a bolt is screwed into the air spoiler from the body side.

[Effect of idea]

As explained above, the air spoiler mounting structure according to the present invention is an air spoiler mounting structure in which the spoiler main body and the vehicle body are fastened together by screw means with a protector that is more flexible than the spoiler main body interposed between the two. The protector's wall thickness is varied in the longitudinal direction of the vehicle body, so that it is thinner at the tightening part of the screw means and gradually becomes thicker as it moves away from the screw means in the longitudinal direction of the vehicle body, so that the external force applied to the vehicle body from the air spoiler can be effectively alleviated. Has excellent effects.
