Description

[Detailed Description of the Invention] This invention relates to a stepped structure for a rear spoiler of an automobile.

Approval has been granted for the installation of rear spoilers on automobiles, and many rear spoilers are being installed on automobiles equipped with tailgates.

In consideration of air flow, a rear spoiler with the same length as the vehicle body width is adopted, but the rear spoiler can be mounted by using a bracket to sandwich the rear spoiler at the edge of the tailgate, or by attaching it to the tailgate or body. There is a method of inserting fasteners such as screws from above the rear spoiler using the provided mounting holes.

However, when the bracket is held between the tailgate edge, the bracket is disposed in a gap between the tailgate edge and the body, resulting in problems such as damage to the body and the like. On the other hand, when installing the rear spoiler by inserting fasteners such as screws from above,
The head of the fastener is exposed from the top surface of the rear spoiler, resulting in an unsightly appearance. At the same time, the exposed head produces wind noise and deteriorates aerodynamic characteristics.

This invention was made with attention to the above circumstances, and its purpose is to provide a rear spoiler mounting structure that allows the rear spoiler to be mounted without damaging the vehicle body due to the bracket and without impairing the appearance or aerodynamic characteristics. It's about doing.

That is, according to this invention, there is a mounting structure for a rear spoiler that is mounted on the rear side of a vehicle body via a mounting bracket, in which a square hole is formed on one of the upper surfaces of the vehicle body that is hidden by the mounted rear spoiler. The mounting bracket has the same square hole formed to correspond to the square hole of the vehicle body, and a support seat formed to follow the top surface of the vehicle body, and the rear spoiler that is connected to the support seat and is also attached. a flange formed to follow the corner curved surface of the vehicle body that is hidden by the vehicle body, and a mounting seat connected to the support seat so that the mounting surface faces rearward,
The rear spoiler has an opening at a portion corresponding to the rear of the vehicle when the mounting seat is attached to the vehicle body, and has a mounting rib formed so that the mounting surface faces toward the rear of the vehicle and overlaps with the mounting seat. death,
The above-mentioned mounting is accomplished by a square tube-shaped screw grommet that can be inserted into the square hole of the support seat, a screw inserted into the screw grommet, and a connecting means that connects the mounting rib to the mounting seat. It is attached to the vehicle body so as to cover the bracket.

This invention will be explained below based on an embodiment shown in the drawings. In Fig. 1, 1 indicates a vehicle body in which a passenger compartment and a luggage compartment (none of which are shown) are integrated, such as a 2-BOX type vehicle, and 2 indicates a top/bottom opening type vehicle installed at the rear of the vehicle. It's a tailgate. A rear spoiler 3 made of resin such as SMC and formed into a substantially U-shape is attached to the upper side of the tailgate 2 on the rear side of the vehicle body 1 along the vehicle width direction.

Here, the rear spoiler 3, which is the main part of this idea,
The mounting structure will be explained with reference to FIGS. 2 to 5.

A space opening rearward is formed between the rear spoiler 3 and the tailgate 2, and a mounting rib 5 integrally formed with the rear spoiler 3 is provided in the space to extend in the vehicle width direction. ing.

Also, the rear spoiler 3 in the tailgate 2
A square hole 6 as a mounting hole is formed in the panel portion 2a, which is the mounting portion.

Reference numeral 4 denotes a mounting bracket, and the mounting bracket 4 includes a support seat 7 formed to fit along the panel portion 2a, and a mounting bracket connected to the support seat 7 to fit along the mounting rib 5 when the rear spoiler 3 is in the mounting position. A flange portion 1 that follows the curved corner side of the panel surface of the tailgate 2 formed on the side of the seat 8 and the support seat 7.
0.

Note that the support seat 7 has a square hole 9a drilled therein with a size slightly larger than the square hole 6, corresponding to the position of the square hole 6, while the mounting seat 8 has a square hole 9a formed in the center of the mounting rib 5. A square hole 9b corresponds to the position of the round hole 5a provided.
is drilled.

In addition, a plate-shaped packing member 11 is attached to the back surface of the support seat 7 to prevent the mounting bracket 4 from accidentally moving on the tailgate 2, and to prevent the mounting bracket 4 from moving inadvertently on the tailgate 2. This prevents scratches from occurring on the panel surface of the tailgate 2.

12 integrally connects a cap portion 12a, a rectangular collar portion 12b that can be inserted into the square hole 9a, and a rectangular columnar locking portion 12c that can be inserted into the square hole 6 in order along the axial direction. This is a plastic screw grommet made of resin. Then, insert this screw grommet 12 into the square hole 9 of the support seat 7 with the locking part 12c at the beginning.
a. Insert it into the square hole 6 of the panel part 2a,
Thereafter, by screwing the screw 13 into the inside of the screw grommet 12 from the cap portion 12a, the locking portion 12c that spreads around the screw grommet 12 locks with each opening edge of the square hole 6 and the square hole 9a, and the panel part 2a
and the support seat 7 of the mounting bracket 4 are connected.

Reference numeral 14 denotes a resin screw grommet formed by integrally connecting a cap portion 14a and a rectangular columnar locking portion 14b that can be fitted into a square hole 9b along the axial direction. And this screw grommet 14
is inserted into the square hole 9b of the mounting bracket 4 in advance, and the head of the screw 15 is removed by inserting the screw 15 from the round hole 5a of the mounting rib 5 toward the inside of the cap portion 14a of the screw grommet 14. The mounting rib 5 and the mounting seat 8 of the mounting bracket 4 are connected to each other by being engaged with the opening edge of the round hole 5a, and by being engaged with the surrounding engaging part 14b and the opening edge of the square hole 9b. That's what I do. However, the rear spoiler 3 can be fixed from the inside by using the screw grommets 12, 14 and the screws 13, 15 as connection means.

However, when installing the rear spoiler 3 on the rear side of the vehicle body 1 using such a mounting structure of the rear spoiler 3,
First, the square hole 6 arranged on the hinge side of the tailgate 2
, so that the square hole 9a faces the square hole 6, and the mounting seat 8 is aligned with the mounting rib 5 of the rear spoiler 3.
Place the support seat 7 of the mounting bracket 4 along the panel surface so as to correspond to the panel surface. Next, insert the screw grommet 12 from the square hole 9a of the mounting bracket 4 toward the square hole 6 of the tailgate 2,
After that, the cap part 1 of the screw grommet 12 is
The support seat 7 is fixed on the panel portion 2a by screwing in the screw 13 from 2a. Here, since the flange portion 10 acts as a rotation stopper for the mounting bracket 4, together with the elastic force of the packing member 11, the mounting bracket 4 is reliably fixed without rattling or displacement. In this way, the mounting bracket 4 is mounted in each square hole 6 (only one is shown in the drawing).

Thereafter, the rear spoiler 3 is placed on the upper side of the tailgate 2 as desired. As a result, the mounting ribs 5 of the rear spoiler 3 are arranged in line with the heads of the screw grommets 14 that have been inserted into the mounting seats 8 of the respective mounting brackets 4 in advance. Then, from this state, if the screws 15 are inserted through the round holes 5a of each mounting rib 5 toward the screw grommet 14, the parts shown in cross sections in FIGS. 2, 3, and 4 will be obtained. The rear spoiler 3 is attached to the vehicle body 1 so as to cover the mounting bracket 4. In other words,
The rear spoiler 3 can be attached to the rear side without exposing the heads of screws or the like from the upper surface of the rear spoiler 3. Therefore, by arranging the mounting bracket 4 at the lower part of the rear spoiler 3, the appearance of the rear spoiler 3 can be improved. Moreover, since the upper surface of the rear spoiler 3 can be made smooth, aerodynamic characteristics can also be improved. Furthermore, since the mounting bracket 4 is fixed on the vehicle body 1, there is no need to worry about damaging the vehicle body 1, unlike in the conventional case.

Furthermore, the structure in which the screw grommets 12 are fitted into both the square holes 6 of the vehicle body 1 and the square holes 9a of the support seat 7, and the screws 13 are inserted into the grommet 12 to fix them, is used when the mounting bracket is attached. , or after installation, the mounting bracket 4 does not rotate relative to the vehicle body 1. Moreover, the rear spoiler 3 can be easily removed by the car user, even if he or she is not a specialist in assembling the car body 1.
It is also relatively easy to clean the hidden parts of the panels of the vehicle body 1. Furthermore, since the square hole 6 formed in the vehicle body 1 for fixing the mounting bracket 4 is covered by the rear spoiler 3, there is no fear that rain, dust, etc. will enter the vehicle interior.

Further, since the mounting bracket 4 is formed with a support seat 7 and a flange portion 10 that extend along the upper surface and corner side curved surface of the vehicle body 1, the mounting bracket 4 can be attached to the vehicle body 1.
Since the positional relationship with respect to the support seat 7 is uniquely determined, it is easy to make the square hole 9a of the support seat 7 correspond to the square hole 6 formed in the vehicle body 1. In addition, after the mounting bracket is attached, the mounting bracket 4 can be reliably positioned together with the screw grommet 12 in the rotational direction. Moreover, the position of the rear spoiler 3 when reinstalled has excellent reproducibility.

Furthermore, since the only shape requirement on the vehicle body side when fixing the mounting bracket 4 is the square hole 6, the rear spoiler 3 can be attached to the vehicle body 1 of relatively any shape.
can be installed.

Furthermore, the mounting surfaces of the mounting seat 5 of the mounting bracket 4 and the mounting rib 5 of the rear spoiler 3 face toward the rear of the vehicle body, and when the rear spoiler 3 is attached to the vehicle body 1, the portion of the mounting seat 8 corresponding to the rear of the vehicle body is Since it is open, the two can be connected from the rear of the vehicle body, and the vehicle body 1 and rear spoiler 3 will not get in the way during the connection work. Moreover, his working posture is excellent.

As explained above, according to this invention, the rear spoiler can be attached to the rear side of an automobile without exposing the head of the fastener from the inside of the rear spoiler to the upper surface of the rear spoiler.

Therefore, it is possible to improve the appearance and aerodynamic characteristics. Moreover, since the mounting bracket is fixed on the vehicle body, there is no possibility that the bracket would move and damage the vehicle body as in the conventional case.

In addition, the structure in which screw grommets are inserted into both the square holes of the vehicle body and the square hole of the support seat, and the screws are inserted and fixed inside the grommets, can be attached to the mounting bracket when or after the mounting bracket is installed. The rear spoiler will not rotate relative to the vehicle body, ensuring secure installation of the rear spoiler. Furthermore, since the rear spoiler can be easily removed by the vehicle user, even if he or she is not a specialist in assembling vehicle bodies, there is an advantage that it is relatively easy to clean the portion of the vehicle body panel that is hidden by the rear spoiler. Furthermore, since the square hole drilled into the vehicle body for fixing the mounting bracket is covered by the rear spoiler, there is no fear of rain, dust, etc. entering the vehicle interior.

In addition, since the mounting bracket is formed with a support seat and a flange that follow the upper surface and corner curved surface of the vehicle body 1, the positional relationship of the mounting bracket with respect to the vehicle body is uniquely determined, and the square hole of the support seat is formed in the vehicle body. This also has the effect of simplifying the work to accommodate the square holes that have been formed. In addition, after the mounting bracket is attached, there is also the effect of ensuring the rotational positioning of the mounting bracket together with the screw grommet. Moreover, the position of the rear spoiler when reinstalled has excellent reproducibility.

Further, since the only shape requirement on the vehicle body side for fixing the mounting bracket is a square hole, there is an advantage that the rear spoiler can be attached to a vehicle body of relatively any shape.

Furthermore, the mounting surfaces of the mounting bracket's mounting seat and the rear spoiler's mounting rib face toward the rear of the vehicle, and the rear spoiler is open at the portion of the mounting seat that corresponds to the rear of the vehicle when it is attached to the vehicle body. , the two can be connected from the rear of the car body, and the car body and rear spoiler will not get in the way during connection work.
Moreover, it has an excellent working posture.
