BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spoiler mounting structure for mounting on a vehicle body to improve aerodynamic characteristics.

[0002]

2. Description of the Related Art Generally, a spoiler of this type is mounted on the upper surface of the rear end portion of a trunk lid of an automobile using screws. In this case, since the rear end of the trunk lid is usually a multi-wall structure including at least an outer panel and an inner panel for reinforcement, it is necessary to penetrate the screw through both the outer panel and the inner panel. is there. Conventionally, as such a spoiler mounting portion structure, the entire screw is inserted from the trunk into the inner panel to be disposed between the inner panel and the outer panel, and the tip of the shaft portion of the screw is moved from the outer panel to the outside. It is known to project the projection and attach a spoiler with the screw (for example, see Japanese Utility Model Laid-Open No. 2-136788). In this device, a large hole that allows the head of the screw to penetrate is formed in the inner panel, and a small hole that allows the shaft of the screw to penetrate is formed in the outer panel. The screw is inserted into the inner surface of the outer panel from the large hole, and a shaft protruding from the small hole to the outer surface of the outer panel is screwed into the lower surface of the spoiler.

[0003]

However, in the conventional spoiler mounting structure, when mounting the spoiler to the vehicle, it is necessary to drill the large hole in the inner panel (the spoiler is generally installed as an option). Since there are many cases, a hole for attaching a spoiler is not formed in the trunk lid in advance.) There is a problem that this operation requires a great deal of labor. That is, drilling work on the outer panel is relatively easy because it is performed downward from the outside of the car with the trunk lid closed, while drilling work on the inner panel is made open. The drilling operation is performed upward with respect to the trunk that is not fixed in position, so that the drilling operation is difficult and time-consuming. This tendency increases as the diameter of the hole to be drilled increases, making it difficult to drill a hole in the inner panel. In addition, in the case of a multi-wall structure having two or more inner panels instead of one inner panel, it is extremely difficult to drill large holes in all the inner panels.

In addition, the rear end of the trunk lid to which the spoiler is mounted has a multi-wall structure in which an inner panel is particularly provided to increase rigidity. Providing the holes is not preferable in maintaining rigidity.

[0005] The present invention has been made in view of such circumstances, and its purpose is to attach a spoiler to a trunk lid having a multi-wall structure.
An object of the present invention is to make the hole to be drilled on the inner panel side as small as possible.

[0006]

In order to achieve the above object, the invention according to claim 1 is directed to a vehicle body having a multi-walled structure including an outer panel and an inner panel separated from the outer panel. The spoiler is arranged on the outer surface side of the outer panel, while the head of the screw is arranged on the inner surface side of the outer panel between the outer panel and the inner panel, and the shaft of the screw passes through the outer panel and Assume that it is screwed into the spoiler. In this device, a band-shaped plate having a bearing surface of the head of the screw is formed at the tip, and an engagement groove that is opened at a width larger than the shaft of the screw and smaller than the head is formed at the tip. . Further, a first through hole through which the head of the screw can pass is formed in the outer panel. further,
In the inner panel, a second through hole through which the tip of the screw fastening tool can penetrate is located at a position facing the first through hole, and a tip of the band-shaped plate at a position away from the second through hole. A third through hole that can be inserted is formed. Then, the head of the screw whose shaft is screwed into the spoiler is inserted through the first through-hole to protrude inward of the outer panel, and the tip of the strip-shaped plate inserted through the third through-hole is inserted. Sandwiched between the inner surface of the outer panel and the head of the screw,
And, in a state where the shaft portion of the screw is fitted in the engagement groove,
The screw is fastened by the tip of a fastening tool inserted from the second through hole.

[0007]

With the above arrangement, the invention according to claim 1 has the following features.
Since the head of the screw can be inserted from the outside through the first through hole while the tip of the screw shaft is slightly screwed into the spoiler side in advance, as in the conventional mounting part structure, It is not necessary to drill a large through hole through which the head of the screw can penetrate, and a small second through hole into which the tip of a fastening tool such as a screwdriver for tightening the head of the screw can be inserted. You only need to drill holes. For this reason, drilling work on the inner panel side is easier than in the conventional mounting structure, and the effect of the spoiler mounting portion on the rigidity of the inner panel is reduced as much as possible. Further, the third through hole for inserting the tip end of the strip plate is formed at a position apart from the second through hole position which is particularly important for maintaining the rigidity of the vehicle body portion. There is no particular loss in the rigidity of the part.

Further, in this case, even if the first through hole through which the head of the screw can penetrate is formed in the outer panel, the shaft portion of the screw is fitted in the engagement groove of the band-shaped plate and the first through hole is formed. Since the tip of the band-shaped plate larger than the hole is sandwiched between the head of the screw and the inner surface of the outer panel, by tightening the screw and screwing it into the spoiler, the head of the screw makes the tip of the band-shaped plate The spoiler is fixed in position by being supported by the inner surface of the outer panel through the outer panel.

Is fixed to the trunk lid 3 with the pair of mounting screws 5 and 7, so that the spoiler 1 can be mounted. The hole of the mounting bracket 13 through which the step of each stepped bolt 15 is inserted is formed to be larger than the step by a predetermined amount, so as to allow relative movement due to heat shrinkage. In FIG. 4, reference numeral 19 denotes a high-mount stop lamp mounted on the center of the spoiler body 11 in the vehicle width direction, and reference numeral 21 denotes a cover for covering the lower surface of the high-mount stop lamp 19.

The rear end of the trunk lid 3 is reinforced with a double-walled structure composed of an outer panel 23 and an inner panel 25 arranged inside and separated from each other.
Outer panels 23 at both ends in the vehicle width direction at the rear end of the trunk lid 3 have a pair of front and rear mounting holes 27 and 29, respectively.
Are formed through the mounting holes 27, 29.
The pair of mounting screws 5 and 7 are passed through. The rear mounting hole 27 has a diameter slightly larger than the head 7a of the rear mounting screw 7, and forms a first through hole through which the head 7a can pass.

The inner panel 25 at a position facing the rear mounting hole 27 downward is formed as a second through hole having a relatively small diameter such that a tip of a driver 31 as a fastening tool described later can be inserted. The stopper hole 33 is formed so as to penetrate, and the rubber stopper 35 is locked in the stopper hole 33. The rubber stopper 35 cushions the rear end of the trunk lid and the vehicle body constituting the trunk room when the trunk lid 3 is opened and closed.

Further, a through hole 37 is formed in the inner panel 25 at a position opposing downward from the front mounting hole 25 as a third through hole through which the band plate 9 can be inserted. Through the through hole 37, the front mounting screw 5 is moved from the inner surface of the outer panel 23 to the front mounting hole 2.
7, and the belt-shaped plate 9 is inserted obliquely rearward into the space between the outer panel 23 and the inner panel 25.

As shown in detail in FIG. 5, the strip-shaped plate 9 is formed with an insertion portion 9a having a predetermined length, a front end portion 9b integrally formed at one end of the insertion portion 9a, and the front end portion 9. Engagement groove 9c. The front end portion 9b has a larger area than the rear mounting hole 29, and the engagement groove 9c is slightly larger than the outer diameter of the shaft portion 7b of the rear mounting screw 7 and has a head portion 7a. The engagement groove 9c extends in the longitudinal direction of the band-shaped plate 9 and is open at the tip. Both surfaces of the distal end portion 9b around the engagement groove 9c constitute a bearing surface 9e for supporting the head 7a of the mounting screw 7 against the inner surface of the outer panel 23. Further, a narrow portion 9d is formed between the insertion portion 9a and the tip portion 9b, and the insertion portion 9a is separated from the tip portion 9b by twisting the insertion portion 9a with respect to the tip portion 9b. Is available.

The front end portion of the mounting bracket 13 has a shaft portion of the mounting screw 5 that passes through the front mounting hole 27 of the outer panel 23 from the inner surface to the outer surface.
3a, and is fixed to the trunk lid 3. The rear end portion of the mounting bracket 13 also has a shaft portion 7b of the mounting screw 7 that passes through the rear mounting hole 29 of the outer panel 23 from the inner surface to the outer surface side, similarly to the front end portion. It is screwed into the hole 13b and fixed in position on the trunk lid 3. The front end 9b of the belt-shaped plate 9 is sandwiched between the head 7a of the rear mounting screw 7 and the inner surface of the outer panel 23, and the shaft 7b of the mounting screw 7 is fitted in the engagement groove 9c. In this state, the mounting screw 7 is tightened, and the head 7a of the mounting screw 7 is fixed to the outer panel 23 by the bearing surface 9e of the distal end 9b.
Is supported against the inner surface of the.

In the drawings, reference numeral 39 denotes a rubber plate for sealing rainwater.

Next, a procedure for attaching the spoiler 1 to the trunk lid 3 will be described. First, a stepped bolt 15 is screwed into each of the embedded nuts 17 at both ends of the spoiler body 11. Each mounting bracket 13 is attached to the spoiler main body 11 and
3, 13, 11 are integrated. Then, the shaft portion 7b of the rear mounting screw 7 is slightly screwed into the rear screw hole 13b of the mounting bracket 11 in advance. Then, the spoiler 1 in this state is arranged at a predetermined position of the trunk lid 3 so that the head 7a of the rear mounting screw 7 projects inward from the rear mounting hole 29 of the outer panel 23 (FIG. 6 (see solid line and dot-dash line).

Next, the front mounting screw 5 inserted into the front mounting hole 27 of the outer panel 23 from the through hole 37 of the inner panel 25 is tightened by a driver inserted from the through hole 37, and the front screw hole 13 of the mounting bracket 13 is tightened.
Screw into a. Thereafter, the distal end portion 9b of the belt-shaped plate 9 is inserted obliquely rearward from the through hole 37 toward the rear mounting screw 7, and the shaft portion 7b of the mounting screw 7 is fitted into the engaging groove 9c. Then, the tip of the driver 31 is inserted through the locking hole 33 of the inner panel 25, and the head 7a of the rear mounting screw 7 is tightened by the driver 31. As a result, the shaft portion 7b of the rear mounting screw 7 is screwed into the rear screw hole 13b of the mounting bracket 13, and the front end portion 9b of the strip plate 9 is positioned between the head portion 7a and the inner surface of the outer panel 23. It is pinched.

Finally, as shown in FIG. 7, a rubber stopper 35 is locked in the locking hole 33 of the inner panel 25,
Installation work is completed. In addition, the strip-shaped plate 9 has a narrowed portion 9d by twisting the insertion portion 9a to form a front end portion 9d.
b, or may be left without being separated to prepare for removal of the spoiler 1 at a later date.

In the embodiment having the above-described structure, the head 7a of the rear mounting screw 7 can be inserted from the outer surface to the inner surface of the outer panel 23 through the rear mounting hole 29 of the outer panel 23. For this reason, it is not necessary to form a large hole on the side of the inner panel 25 into which the head 7a can be inserted, and it is sufficient to form a small hole into which the tip of the driver can be inserted. Therefore, the drilling work is greatly facilitated and rigidity is particularly required as compared with a conventional mounting structure in which a large hole needs to be drilled on the side of the inner panel 25 where drilling work is difficult. A reduction in rigidity due to drilling at the rear end of the trunk lid 3 can be prevented as much as possible.
Since the relatively large through-hole 37 formed in the inner panel 25 is formed at a position forward of the rear end of the trunk lid 3, the through-hole 37 is formed particularly behind the trunk lid 3 which requires rigidity. There is no loss of rigidity at the ends.

In this case, even if the rear mounting hole 29 of the outer panel 23 is formed larger than the head 7a of the mounting screw 7, the shaft 7b of the mounting screw 7 is fitted in the engaging groove 9c of the belt-shaped plate 9. The tip 9b of the band-shaped plate 9 is attached to the head 7a of the mounting screw 7 and
Of the head 7a
Is supported by the inner surface of the outer panel 23 via the end portion 9b of the strip-shaped plate 9, and the position of the spoiler 1 can be reliably fixed.

Further, in the present embodiment, a second through hole for inserting the driver 31 into the rear mounting screw 7 is formed on the inner panel 25 in advance to lock the rubber stopper 35. Since the stop hole 33 is also used, the work of drilling the second through-hole can be omitted, and the locking hole 33 is blocked by the rubber stopper 35 being locked. 3 can also contribute to the improvement of appearance in the open state.

In addition, since a through hole 37 as a third through hole for inserting the strip plate 9 is also used as a hole for inserting the front mounting screw 5, a new drilling operation is added. Thus, a structure in which one mounting portion is fixed in position by two mounting screws 5 and 7 can be easily configured.

It should be noted that the present invention is not limited to the above embodiment, but includes various other modifications. For example, in the above embodiment, the outer panel 23 and the inner panel 25 each have a double wall structure, but the present invention is not limited to this, and an outer panel in which two or more sheets are laminated may be used. The present invention may be applied to a multi-wall structure in which two or more inner panels are separated from each other.

In the above embodiment, the engaging groove 9c formed in the band-shaped plate 9 extends in the longitudinal direction and is opened at the tip. However, the present invention is not limited to this. For example, the engaging groove 9c extends in the direction orthogonal to the longitudinal direction. Alternatively, it may be opened to the side of the distal end portion 9b.

In the above embodiment, the rubber stopper 35
Although the second through hole is used as the second through hole by using the locking hole 33, the second through hole may be provided separately from the locking hole 33.

Further, in the above embodiment, the spoiler main body 11 and the mounting bracket 13 are formed as separate bodies. However, the present invention is not limited to this, and the spoiler main body 11 and the mounting bracket 13 may be integrally formed by, for example, synthetic resin molding.

[0029]

As described above, according to the spoiler mounting structure of the first aspect of the present invention, the head portion of the outer panel is fixed to the spoiler side while the screw shaft is slightly screwed into the spoiler side. (1) Since the outer panel can be inserted from the outer surface side to the inner surface side through the through hole, it is possible to omit the formation of a large hole enough to insert the head into the inner panel side, and the tip of a fastening tool such as a driver Can be formed as small holes as can enter. For this reason, the drilling work can be performed extremely easily, and a multi-wall structure is provided, compared with the conventional mounting structure that requires drilling a large hole on the side of the inner panel where drilling work is difficult. In addition, it is possible to prevent a decrease in rigidity as much as possible by drilling holes in a vehicle body part particularly requiring rigidity.
Moreover, in this case, the relatively large-diameter third through hole formed on the inner panel side is formed at a position distant from the second through hole position. There is no loss in rigidity.

Further, even if the first through hole on the outer panel side is formed larger than the head of the screw, the tip of the strip-shaped plate is fitted in the engagement groove of the strip-shaped plate with the shaft of the screw being fitted inside. Since the part is sandwiched between the head of the mounting screw and the inner surface of the outer panel, the head of the screw can be supported on the inner surface of the outer panel via the tip of the strip-shaped plate. Can be reliably fixed in position.
