Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a two-stage rear spoiler having a second spoiler on a first spoiler.

(Prior Art) A rear spoiler is attached to the rear of an automobile to improve its high-speed stability, and some of them are equipped with a first spoiler as shown in Fig. 8 to further enhance the high-speed stability. There is a two-stage rear spoiler 14 provided above the spoiler 10 with a second spoiler 12.

Conventional two-stage rear spoiler 1 shown in Figure 8
4, as shown in FIG. 4 showing the A-A cross section, the first spoiler is fixed by fixing bolts 18 etc. embedded in the legs 16 of the second spoiler to the upper surface of the first spoiler 10 with nuts 20 etc. The spoiler 10 and the second spoiler 12 are integrated, and as shown in FIG. It can be attached to the vehicle body outer plate 22 by fixing it with a screw or the like.

Further, as another conventional two-stage rear spoiler, there is a two-stage rear spoiler 24 shown in cross-sectional views in FIGS. 6 and 7. Note that FIGS. 6 and 7 show cross sections at the same positions as AA and BB in FIG. 8.

The two-stage rear spoiler 24 is constructed by directly fixing the first spoiler 26 and the second spoiler 28 to the vehicle body outer panel 22 with fixed parts such as bolts 18 and nuts 20.
and the second spoiler 28 are integrated, and the first
The spoiler 26 is formed with an opening 32 through which the second spoiler leg 30 passes.

(Problem that the invention attempts to solve) However, the former two-stage rear spoiler 14
In this case, during the installation work on the vehicle body outer panel 22,
Due to the integration of the first spoiler 10 and the second spoiler 12, it has become heavy and bulky and must be held at the same time, which poses a problem that the work is not only difficult but also hard work. In addition, in order to eliminate this problem, after the first spoiler 10 is fixed to the vehicle body outer plate 22, the second spoiler 1 is attached on the first spoiler 10.
2 may be fixed, but the outer plate 22 of the vehicle body
Since it becomes impossible to fix the second spoiler 12 because of the obstruction, it is necessary to fix the second spoiler 12 to the first spoiler 10 first. Therefore, with the two-stage rear spoiler 14, it has not been possible to eliminate the above-mentioned problem of poor installation workability to the outer panel of the vehicle body.

In addition, in the case of the latter two-stage rear spoiler 24, there are bolt insertion holes (usually three) for fixing the first spoiler 26 and bolt insertion holes (usually two) for fixing the second spoiler 28. Both holes (usually five) had to be made in the vehicle body outer panel 22, and the work could not be said to be easy due to the large number of holes. Moreover, there is also the problem that the paint on the outer body panel 22 around the periphery of the bolt insertion hole is peeled off during drilling, and the outer panel 22 of the vehicle body is susceptible to rust.

Therefore, this invention aims to solve both the problems that conventional two-stage rear spoilers have, namely, the problem of poor installation workability on the outer skin of the car body and the problem that rust easily occurs on the outer skin of the car body. be.

(Means for Solving the Problems) The gist of this invention is that in a two-stage rear spoiler, an opening is provided at a predetermined position of the first spoiler, extending from the top surface of the spoiler through the inside to the rear surface of the second spoiler. A fixing metal fitting is fixed to the bottom of the leg, a second spoiler is placed on the first spoiler so that the fixing metal fitting enters the opening from the top surface of the first spoiler, and the fixing metal fitting is fixed to the first spoiler. This two-stage rear spoiler is characterized in that the first spoiler and the second spoiler are integrated by being fixed to the first spoiler by a fixed part such as a bolt inserted into an opening from the rear surface of the spoiler.

(Function) In the two-stage rear spoiler according to this invention, the legs of the second spoiler are placed at predetermined positions on the upper surface of the first spoiler, which is fixed in advance to the outer skin of the vehicle body using fixed parts such as bolts and nuts. The fixing metal fittings fixed to the bottom of the legs are positioned in the openings on the top and rear surfaces of the first spoiler, and the fixing metal fittings are fixed to the first spoiler with a fixing part such as a bolt inserted through the openings on the rear side of the first spoiler. Thus, the first spoiler and the second spoiler are integrated.

Therefore, the first spoiler and the second spoiler are fixed to the outer skin of the vehicle body in a separated state, so there is no need to hold the first and second spoilers at once to install the two-stage rear spoiler. , it is possible to install a two-stage rear spoiler even with light work.

In addition, only the holes necessary for fixing the first spoiler are drilled in the outer panel of the vehicle body, which simplifies the drilling work as the number of holes required is reduced. The outer panels of the vehicle body are less likely to rust.

(Example) This invention will be described below based on an example using the drawings.

The two-stage rear spoiler 34 is a
The first spoiler 36 is placed and fixed on the surface of the second spoiler.
and a second spoiler 38 placed and fixed on the upper surface of the first spoiler 36.

First spoiler 36 and second spoiler 38
In this case, a metal insert 44 or a fixing fitting 46 is completely or partially embedded and fixed in a main body 40, 42 made of hard plastic or hard foamed plastic.

The main bodies 40 and 42 of the first and second spoilers are
In addition to those made of a single hard plastic or hard foamed plastic, as in the two-stage rear spoiler 24 shown in FIGS. 4 and 5, a core material 46 made of hard plastic or the like is surrounded by polyurethane foam or the like. There is also a structure covered with a surface layer 50. The main body 40 of the first spoiler has a recess 54 formed at a predetermined position on the upper surface 51 of the main body, into which the leg portion 52 of the second spoiler 36 fits.
4 is formed with an opening 56 extending from the top surface 51 of the main body through the inside of the main body to the rear surface 55 of the main body. Note that 57 is a hole for inserting the rear wiper shaft, which may not be necessary depending on the vehicle model. Further, the main body 42 of the second spoiler has two leg portions 52 on the lower surface, and a fixing metal fitting 46 protrudes from the bottom surface of the leg portions 52.

On the other hand, the metal insert 44 embedded in the first spoiler 36 also serves to reinforce the main body 40, and has a vehicle body fixing part 58 and a second spoiler fixing part 60 formed at predetermined parts. The vehicle body fixing portion 58 is a portion that fixes the first spoiler 36 to the vehicle body outer panel 22 and is substantially parallel to the vehicle body outer panel 22, and the second spoiler fixing portion 60 fixes the second spoiler 38 to the first spoiler 36. This is the part for fixing to the rear opening 56a of the first spoiler main body.

Two fastening part insertion holes 65 and 66 in the metal insert 44 and the fastening part 46 coincide within the opening 56. Then, a fixed part 62 such as a bolt is inserted into the opening 56a on the rear surface of the first spoiler 36, and is screwed or engaged with a fixed part 64 such as a nut welded to the metal insert 44 of the first spoiler. Thereby, the second spoiler 38
It is fixed onto the spoiler 36, completing the assembly of the two-stage rear spoiler.

(Effects of the invention) Since this invention has the above-mentioned configuration, when installing a two-stage rear spoiler to the vehicle body, the first spoiler and the second spoiler can be installed separately. Since it is not necessary to hold the first and second spoilers at the same time, the work can be done easily. In addition, the holes that need to be drilled in the vehicle body exterior panel during installation work are only the holes for fixing the first spoiler, and the number of holes is small, making the drilling work easier and Rust on the car body due to peeling of the paint on the panels is also less likely to occur, which also has the effect of improving the durability of the car body.
