DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a rear spoiler used by being attached to a rear part of a vehicle body of an automobile.

[0002]

2. Description of the Related Art Conventionally, as an example of a rear spoiler, there is a rear spoiler formed by blow molding a synthetic resin to form a hollow wing shape with an upper wall portion and a lower wall portion extending in the vehicle width direction. is there. According to such a configuration, the weight of the rear spoiler can be reduced because the rear spoiler has a hollow shape.
In addition, the molding operation is easy, and there is an advantage that the manufacturing cost can be reduced.

[0003]

However, in the above-mentioned conventional rear spoiler, since its entire shape is hollow, if each part of the rear spoiler is formed to be thin, its rigidity is considerably reduced. Therefore, conventionally, when the rear spoiler is mounted on the rear part of the body of an automobile, there is a problem that bending deformation occurs in the vertical thickness direction and vibration occurs, so that so-called wobbling is likely to occur. In particular, this kind of rear spoiler
By attaching the front edge to the rear of the vehicle body, it is necessary to set the rear edge so as to protrude more rearward than the rear of the vehicle body. If the overhang is increased,
The rigidity of the overhanging portion is further reduced, and the above-mentioned problem has become more remarkable. On the other hand, if the thickness of each part of the rear spoiler is increased, the above problem can be suppressed to some extent, but this increases the weight of the rear spoiler and increases the manufacturing cost.

The present invention was conceived in view of such circumstances, and is intended to minimize the increase in the weight of the rear spoiler and the manufacturing cost.
It is an object of the present invention to efficiently increase the rigidity of the rear spoiler so that vibrations and the like are hardly generated.

[0005]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means.

According to the present invention, an upper wall portion and a lower wall portion extending in the vehicle width direction have a hollow longitudinal wing shape in a short side direction, and a front edge portion of the lower wall portion is an automobile. The rear spoiler has a rear spoiler structure in which the rear end edges of the upper wall portion and the lower wall portion project rearward of the rear portion of the vehicle body by being attached to the rear portion of the vehicle body. A bead is formed at a position behind the rear spoiler at the rear of the vehicle body at a position rearward of the vehicle so that a part of the lower wall portion is formed to protrude upward so as to extend in the vehicle width direction as a whole. And a plurality of first beads provided at intervals in the vehicle width direction and a plurality of first beads positioned between the plurality of first beads. In the vehicle width direction to connect Bill has a plurality of second bead,
The plurality of first beads are bent and formed so as to protrude above the plurality of second beads, and are connected to the upper wall portion.

In the present invention, a bead is formed in the rear spoiler. However, since the bead is formed by bending a part of the lower wall of the rear spoiler upward, the bead is formed by the presence of the bead. Is increased in rigidity or strength, and in particular, the strength against a vertical load is increased. The bead is
Since the rear spoiler is provided at a position rearward of the vehicle relative to a position where the rear spoiler is mounted on the rear part of the vehicle body, the rigidity of a portion of the rear spoiler projecting rearward of the vehicle from the rear part of the vehicle body can be efficiently increased. Further, since the bead is formed so as to extend in the longitudinal direction of the rear spoiler as a whole, the rigidity of the rear end edge of the rear spoiler projecting rearward of the vehicle from the rear of the vehicle body is increased by the presence of the bead. Can be enhanced. Therefore, in the present invention, it is possible to increase the rigidity of the portion of the rear spoiler that protrudes more rearward than the rear part of the vehicle body without increasing the weight of the entire rear spoiler without increasing the thickness of each part of the rear spoiler as much as possible. Thus, an effect is obtained that various portions of the rear spoiler can be easily prevented from being bent or vibrated. Of course,
In the present invention, since the rear spoiler is conventionally hollow, the rear spoiler can be manufactured at a low cost by, for example, blow molding.

[0008]

In the present invention, a plurality of portions of the upper wall portion and the lower wall portion of the rear spoiler are integrally connected in the thickness direction of the rear spoiler via the first bead. Therefore, the rigidity of the rear spoiler can be more efficiently increased, and vibration and bending deformation in the vertical thickness direction of the rear spoiler can be further prevented from occurring at the rear end edge of the rear spoiler. Further, since a plurality of the first beads are provided at intervals in the vehicle width direction, and the plurality of the first beads are connected to each other by the second bead,
The rigidity of the entire length region of the rear spoiler can be further increased by connecting these beads to each other. Further, the second bead may be formed as a bead having a relatively small size, which is advantageous in suppressing an increase in the weight of the rear spoiler.
That is, if the upper part of the entire length of the bead provided on the rear spoiler is connected to the upper wall of the rear spoiler, the bead becomes a very large size,
Although the weight of the rear spoiler is increased, such a problem can be eliminated according to the above configuration.

In another preferred embodiment of the present invention,
The lower wall of the rear spoiler is provided with a third bead forming a recess for disposing a washer nozzle provided at the rear of the vehicle body below the rear spoiler. The lower surface is provided with an inclined surface portion that is inclined backward and downward so that the washer liquid ejected from the washer nozzle hits the lower surface and is supplied to the surface of the rear window glass located below the lower surface. can do.

According to such a configuration, by disposing the washer nozzle in the recess formed by the third bead provided in the rear spoiler, the washer nozzle and the rear spoiler can be prevented from interfering with each other without interfering with each other. And the rear spoiler can be mounted properly. When the washer liquid is jetted from the washer nozzle, the washer liquid strikes the inclined surface of the lower surface of the third bead and is supplied to the surface of the rear window glass below the third bead. Therefore, for example, even when the washer nozzle is provided in a positional relationship in which it is difficult to inject the washer liquid directly to the surface of the rear window glass in relation to the rear window glass, it is possible to surely inject the washer liquid to the rear window glass. The advantage that can be obtained is obtained.

Further, since the inclined surface of the third bead is inclined backward and downward, the recess of the rear spoiler formed by the third bead and the washer nozzle disposed in the recess are provided in the vehicle. It is also possible to make it hard to look unsightly from the rear outside. Therefore, an advantage that the appearance of the rear portion of the vehicle body can be improved is also obtained. That is, conventionally, when the washer nozzle is disposed below the rear spoiler, for example, a notch recess having a relatively large opening area is formed on the lower surface of the rear spoiler, and the washer injected from the washer nozzle disposed in the notch recess is provided. The liquid was allowed to directly hit the rear window glass. However, in such a conventional structure, when the rear spoiler is viewed from the rear of the vehicle, the opening of the cut-out recess and the washer nozzle located at the back of the opening look unnatural, which deteriorates the appearance of the vehicle. Was. On the other hand, according to the configuration of the present invention, there is no such a problem, and the appearance of the vehicle can be improved.

FIG. 1 is a partially cutaway perspective view showing an example of the structure of a rear spoiler according to the present invention. FIG. 2 is a sectional view taken along line II-II of FIG. FIG. 3 is a sectional view taken along line III-III of FIG. FIG. 4 is a sectional view taken along line IV-IV of FIG. FIG.
FIG. 5 is a sectional view taken along line VV of FIG. 1. In these figures,
Arrow Fr indicates the front of the vehicle, arrow Up indicates the upper direction in the vehicle height direction, and arrow Ou indicates the outer side in the vehicle width direction.

In FIG. 1, a rear spoiler 1 is mounted on a rear upper surface of a roof 2 of an automobile, and is used as a so-called roof spoiler. Needless to say, the present invention can be applied to a case where the rear spoiler is provided on the roof, instead of being provided on the roof, or on the rear of the upper surface of the trunk room, and the vehicle body referred to in the present invention includes the back door. It is. In FIG. 1, a part (left half) of the rear spoiler 1 is omitted, but the rear spoiler 1 extends from one end of the roof 2 in the vehicle width direction to the other end, and its center in the longitudinal direction is centered. As a symmetrical shape.

The rear spoiler 1 is made of a synthetic resin formed by, for example, a blow molding method, and has a short-side vertical cross-sectional shape which is basically such that a downforce can be generated when an automobile is running. It is a hollow wing shape with the wings turned upside down. More specifically, the rear spoiler 1 integrally connects an upper wall portion 10 having a vertical cross-sectional shape bulging upward and a lower wall portion 11 having a vertical cross-sectional shape bulging downward at the positions of their front and rear ends. The upper wall 10 and the lower wall 11 both extend in the vehicle width direction.

However, the lower wall 11 is provided with an appropriate number of bolts 4 and clip pins 4A.
A plurality of first beads 31, a plurality of second beads 32, and one third bead 33 are provided.

The bolts 4 are for fixing the rear spoiler 1 to the rear part of the roof 2 and are mounted at both ends in the longitudinal direction of the lower wall part 11 at their upper parts. The bolt 4 can be embedded in the rear spoiler 1 by an insert molding method. 2, the rear portion 20 of the roof 2 to which the rear spoiler 1 is attached has a hollow structure in which, for example, an outer member 20a and an inner member 20b are connected. The rear spoiler 1 has a front end edge portion of the lower wall portion 11 disposed on the outer member 20a, and the bolt 4 is inserted into a bolt insertion hole 21 of the outer member 20a.
And is screwed to the nut 22, so that the bolt 4 and the nut 22 are fixedly attached to the outer member 20a by tightening.

The clip pins 4A are for assisting the mounting and fixing of the rear spoiler 1 using the bolts 4. A plurality of the clip pins 4A are provided at an appropriate interval in a longitudinally intermediate portion of the rear spoiler 1. This clip pin 4A
As with the bolt 4, a part of the rear spoiler 1 can be buried in the rear spoiler 1 by the insert molding method. As can be seen in FIG.
A is a swelling portion 40a capable of expanding and contracting elastically deformable on its shaft portion 40.
And is inserted into the pin insertion hole 24 of the outer member 20a in a retaining state. In addition,
In the present invention, the rear spoiler 1 may be more securely and firmly attached to the rear portion 20 of the roof 2 by using an adhesive, for example, in addition to the means using the clip pins 4A and the bolts 4.

As shown in FIG. 1, the plurality of first beads 31 are provided at appropriate intervals in the vehicle width direction. These multiple first
Each of the beads 31 has a width La in the vehicle width direction and a width Lb in the vehicle front-rear direction formed to be relatively small, but as shown well in FIG. A part of the part 11 is largely bent upward, and the upper part thereof is integrally connected to the upper wall part 10. Each of the first beads 31 is attached to the roof 2 at a position where the rear spoiler 1 is mounted, that is, the lower wall portion 11 of the rear spoiler 1.
Is located on the vehicle rear side with respect to the fixing position of the bolt 4 or the clip pin 4A for fixing the vehicle to the roof 2.

As shown in FIG. 1, the plurality of second beads 32 are located between the plurality of first beads 31, and the plurality of first beads 31,
These beads extend in the vehicle width direction so as to connect each other. Each of the plurality of second beads 32 is configured as shown in FIG.
As shown in FIG. 3 and FIG. 3, a part of the lower wall portion 11 of the rear spoiler 1 is bent upward, but is not bent as much as the first bead 31 described above. Therefore, it is not connected to the upper wall 10 of the rear spoiler 1. Like the first bead 31, the second bead 32 is also located on the rear side of the vehicle from the place where the rear spoiler 1 is attached to the roof 2.

As shown in FIG. 1, the third bead 33 is provided substantially at the center of the lower wall 11 in the longitudinal direction. The third bead 33 not only plays a role in increasing the strength of the rear spoiler 1 like the other first bead 31 and the second bead 32, but also, as is well shown in FIG. Also serves to avoid interference with the rear spoiler 1. That is, this third
Is a bead formed by bending a part of the lower wall portion 11 of the rear spoiler 1 upward, and a recess 34 serving as a space for disposing the washer nozzle 5 is formed below the third bead 33. Have been. Washer nozzle 5
Is provided at a substantially central portion in the longitudinal direction of the rear portion 20 of the roof 2 of the vehicle body so as to protrude upward from below the outer member 20a.

The recess 34 extends rearward of the vehicle from the location where the washer nozzle 5 is disposed, and is formed so as to also serve as a passage for washer liquid injected from the washer nozzle 5. A portion of the lower surface of the third bead 33 forming the concave portion 34, which is rearward of the washer nozzle 5 in the vehicle, is formed as an inclined surface portion 35 inclined backward and downward, and the inclined surface portion 35 is a rear portion of the vehicle body. 20 is located above the rear window glass 6 of the vehicle extending rearward of the vehicle.

Next, the operation of the rear spoiler will be described.

First, in the rear spoiler 1, the front edge of the lower wall 11 is attached to the roof 2, and the lower wall 1
The rear edge of each of the upper wall portion 1 and the upper wall portion 10 protrudes rearward of the vehicle from the rear portion of the roof 2. Therefore, the rigidity of the portion projecting rearward of the vehicle is small, and the vehicle easily vibrates easily in the vertical direction when the vehicle is running. However, in the rear spoiler 1, the first bead 31, the second bead 32, and the third bead 33 (only one of the third bead 33) are provided at portions protruding rearward of the vehicle from the roof 2. ), The rigidity of the rearwardly projecting portion of the rear spoiler 1 at the rear of the vehicle is enhanced by the beads. Therefore, the overhanging portion of the rear spoiler 1 is prevented from easily vibrating in the vertical direction.

In particular, each of the plurality of first beads 31 is connected to the upper wall portion 10, and further, the plurality of first beads 31 are connected to the second beads 3 extending in the vehicle width direction.
Due to the connection of the rear spoiler 1 to the rear spoiler 1, the rigidity of the rear spoiler 1 can be increased more efficiently and at various points in the longitudinal direction. As a result, the rear spoiler 1 is given a sense of rigidity, and vibration in the vertical thickness direction can be made more unlikely.

On the other hand, when the washer liquid is ejected from the washer nozzle 5, the washer liquid hits the inclined surface 35 on the lower surface of the third bead 33 as shown by the arrow in FIG. 6 is supplied to the surface. By employing such a washer liquid supply method, it is not necessary to make the washer nozzle 5 directly face the surface of the rear window glass 6. Therefore, it is possible to eliminate the necessity of protruding the washer nozzle 5 from the upper surface of the roof 2 with a large dimension, thereby facilitating the mounting of the washer nozzle 5. Further, since the inclined surface portion 35 has a downwardly inclined shape, the washer liquid attached to the inclined surface portion 35 can be almost surely dripped onto the surface of the rear window glass 6. When the rear spoiler 1 is viewed from the vehicle rear side, the opening of the concave portion 34 is largely inconspicuous. In addition, the end of the inclined surface portion 35 is located at a position lower than the washer nozzle 5, and the washer nozzle 5 is blindfolded and cannot be seen from the outside. Therefore, it is possible to prevent the rear spoiler 1 from appearing complicated, and to improve its appearance.

The specific configuration of each part of the structure of the rear spoiler according to the present invention is not limited to the above-described embodiment.
Various design changes are possible.

In the above embodiment, the third bead for arranging the washer nozzle is provided on the rear spoiler. Of course, when the washer nozzle is not provided on the rear portion of the vehicle body, or when the rear spoiler and the washer nozzle are connected to each other. In the case where the third bead is provided so as to be displaced in the vehicle front-rear direction, it is not necessary to provide the third bead as described above in the rear spoiler.

In the present invention, the first bead and the second bead are provided as beads provided on the rear spoiler, but the specific configuration of the beads is not limited to the above embodiment.
