Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spoiler mounting structure used for mounting on a vehicle body to improve aerodynamic characteristics.

[0002]

[Prior art]

 Generally, this type of spoiler is attached to the upper surface of the rear end portion of the trunk lid of the automobile with screws. In this case, since the rear end portion of the trunk lid is usually formed as a multi-wall structure including at least an outer panel and an inner panel for reinforcement, the screw needs to pass through both the outer panel and the inner panel. There is. As such a spoiler attachment structure, conventionally, the entire screw is inserted from the inside of the trunk into the inner panel and is arranged between the inner panel and the outer panel, and the tip of the screw shaft is externally attached to the outer panel. It is known that the spoiler is mounted on the spoiler and attached to the spoiler with this screw (for example, see Japanese Utility Model Laid-Open No. 2-136788). In this product, a large hole is formed in the inner panel to allow the screw head to pass through, and a small hole in the outer panel to allow the screw shaft to pass through. At this time, the screw is inserted from the large hole to the inner surface side of the outer panel, and the shaft portion protruding from the small hole to the outer surface side of the outer panel is screwed into the lower surface of the spoiler.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional spoiler mounting structure, it is necessary to drill the large holes in the inner panel when mounting the spoiler to the automobile (the spoiler is often installed as an option, so the trunk lid is not The spoiler mounting hole is not opened in advance), and there is a problem that this work requires a lot of work. In other words, drilling work on the outer panel is relatively easy because it is performed from the outside of the vehicle downward on the closed trunk lid, while drilling work on the inner panel is open. Since it is performed upward with respect to the trunk that is not fixed in position, the drilling work is difficult and time-consuming. This tendency increases as the diameter of the hole to be drilled increases, making it difficult to drill the inner panel. In addition, when the inner panel has a multi-wall structure with two or more walls instead of one, 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 attached is provided with an inner panel in order to increase the rigidity, and has a multi-wall structure. It is not preferable to provide such large holes in order to maintain rigidity.

The present invention has been made in view of such circumstances, and an object thereof is to provide a hole for drilling on the inner panel side when a spoiler is attached to a trunk lid having a multi-wall structure. The goal is to make the diameter as small as possible.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the invention according to claim 1 is such that a spoiler is provided on an outer surface side of the outer panel with respect to a vehicle body part having a multi-wall structure including an outer panel and an inner panel separated from the outer panel. On the other hand, the head of the screw is arranged between the outer panel and the inner panel and on the inner surface side of the outer panel, and the shaft part of the screw penetrates the outer panel and is screwed into the spoiler. Assumption. In this structure, a strip-shaped plate having a bearing surface of the head of the screw is formed at the tip, and an engaging groove that is wider than the shaft of the screw and smaller than the head is formed at the tip of the plate. To do. In addition, 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 at a position facing the first through hole, and a tip of the strip plate at a position apart from the second through hole. And a third through hole into which the part can be inserted. Then, the head portion of the screw having the shaft portion screwed into the spoiler is inserted into the first through hole to project inward of the outer panel, and the tip end of the belt-like plate inserted from the third through hole. Fastening by inserting the screw part through the second through hole with the inner part of the outer panel and the head part of the screw sandwiched, and with the shaft part of the screw fitted in the engagement groove. It is designed to be tightened by the tip of the tool.

[0007]

[Action]

 With the above structure, in the device according to the first aspect, the head of the screw is inserted into the inside from the outside through the first through hole in a state where the tip of the shaft of the screw is slightly screwed into the spoiler side in advance. Therefore, it is not necessary to drill a large through hole on the inner panel side through which the screw head can pass, as in the conventional mounting structure, and a screwdriver or the like for tightening the screw head cannot be used. All that is required is to drill a small second through hole into which the tip of the fastening tool can be inserted. Therefore, the drilling work on the inner panel side is easier than the conventional mounting portion structure, and the influence of the spoiler mounting portion on the rigidity of the inner panel is minimized. Further, the third through hole for inserting the tip end portion of the strip-shaped plate is formed at a position away from the second through hole position which is particularly important for maintaining the rigidity of the vehicle body portion, and thus has a multi-wall structure. The rigidity of the vehicle body is not particularly impaired.

Moreover, in this case, even if the outer panel is formed with the first through hole through which the head of the screw can pass, the shaft portion of the screw is fitted into the engaging groove of the strip plate and the first through hole is formed. Since the tip of the strip plate that is larger than the through hole is sandwiched between the screw head and the inner surface of the outer panel, tightening the screw and screwing it into the spoiler causes the screw head to The spoiler is positionally fixed by being supported by the inner surface of the outer panel via the tip portion.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show a spoiler mounting structure according to an embodiment of the present invention, 1 is a spoiler, 3 is a trunk lid as a vehicle body part to which the spoiler is mounted, and 5 and 7 are A pair of front and rear mounting screws for mounting the spoiler 1 on the trunk lid 3 and a strip plate 9 for supporting the rear mounting screw.

The spoiler 1 is composed of a spoiler body 11 and a pair of mounting brackets 13 and 13 (see FIG. 4) for attaching both end portions of the spoiler body 11 in the vehicle width direction to the trunk lid 3. The pair of mounting brackets 13 and 13 are previously attached to both ends of the spoiler body 11 by a pair of stepped bolts 15 and 15 and are integrated with the spoiler body 11. The spoiler body 11 is formed in a hollow shape by blow molding using a synthetic resin. At this time, a nut 17 into which the stepped bolts 15 are screwed is embedded in the spoiler body 11 by insert molding. Each of the mounting brackets 13 is formed with screw holes 13a, 13b for screwing the pair of mounting screws 5, 7 at the front and rear positions, which are integrated with the spoiler body 11. The spoiler 1 can be mounted by fixing each mounting bracket 13 to the trunk lid 3 with the pair of mounting screws 5 and 7. The hole of the mounting bracket 13 through which the stepped portion of each stepped bolt 15 is inserted is formed to be larger than the stepped portion by a predetermined amount to allow relative movement due to thermal contraction. . Further, in FIG. 4, reference numeral 19 is a high mount stop lamp mounted on the central portion of the spoiler body 11 in the vehicle width direction, and reference numeral 21 is a cover for covering the lower surface of the high mount stop lamp 19.

The rear end portion of the trunk lid 3 is reinforced by an outer panel 23 and an inner panel 25 that is spaced apart from each other inside of the trunk lid 3 to have a double wall structure. A pair of front and rear mounting holes 27 and 29 are formed through the outer panels 23 at both ends in the vehicle width direction at the rear end of the trunk lid 3, and these pair of mounting holes 27 and 29 form the pair of mounting holes 27 and 29. The mounting screws 5 and 7 are passed through. The rear mounting hole 27 is set to have a hole diameter slightly larger than the head portion 7a of the rear mounting screw 7 and constitutes a first through hole through which the head portion 7a can pass.

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

Further, a through hole 37 as a third through hole having a size through which the strip plate 9 can be inserted is formed in the inner panel 25 at a position facing the front mounting hole 25 downward. Through the through hole 37, the front side mounting screw 5 is inserted into the front side mounting hole 27 from the inner surface side of the outer panel 23, and the strip plate 9 is slanted rearwardly into the space between the outer panel 23 and the inner panel 25. It is supposed to be.

As shown in detail in FIG. 5, the band-shaped plate 9 is formed on the insertion portion 9 a having a predetermined length, a tip portion 9 b integrally formed at one end of the insertion portion 9 a, and the tip portion 9. And an engaging groove 9c. The tip portion 9b has a larger area than the rear mounting hole 29, the engaging groove 9c is slightly larger than the outer diameter of the shaft portion 7b of the rear mounting screw 7, and the head portion The width is set smaller than the outer diameter of 7a, and the engagement groove 9c extends in the longitudinal direction of the strip plate 9 and is opened at the tip. Both sides of the tip portion 9b around the engagement groove 9c form a bearing surface 9e for supporting the head portion 7a of the mounting screw 7 against the inner surface of the outer panel 23. Further, a narrowed portion 9d is formed between the insertion portion 9a and the tip portion 9b, and the insertion portion 9a is twisted with respect to the tip portion 9b to be separated from the tip portion 9b by the narrowed portion 9d. Is able to.

At the front end side portion of the mounting bracket 13, the shaft portion of the mounting screw 5 penetrating the front side mounting hole 27 of the outer panel 23 from the inner surface side to the outer surface side is screwed into the front screw hole 13a and the trunk is formed. The position is fixed to the lid 3. The rear end portion of the mounting bracket 13 also has a shaft portion 7b of the mounting screw 7 penetrating the rear mounting hole 29 of the outer panel 23 from the inner surface side to the outer surface side similarly to the front end portion. It is screwed into the screw hole 13b and fixed in position on the trunk lid 3. The tip portion 9b of the strip-shaped plate 9 is sandwiched between the head portion 7a of the rear mounting screw 7 and the inner surface of the outer panel 23, and the shaft portion 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 portion 7a of the mounting screw 7 is supported against the inner surface of the outer panel 23 by the bearing surface 9e of the tip portion 9b.

Reference numeral 39 in the drawing is a rubber plate for sealing rainwater.

Next, in order to explain the procedure for attaching the spoiler 1 to the trunk lid 3, first, by screwing the stepped bolts 15 into the embedded nuts 17 at both ends of the spoiler body 11, The mounting brackets 13 are mounted on the spoiler body 11 to integrate the three members 13, 13, 11. 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 that state is arranged at a predetermined position of the trunk lid 3, and the head portion 7a of the rear side mounting screw 7 is inwardly projected from the rear side mounting hole 29 of the outer panel 23 (Fig. See the solid line and the alternate long and short dash line in 6).

Next, the front side mounting screw 5 inserted into the front side mounting hole 27 of the outer panel 23 from the through hole 37 of the inner panel 25 is tightened by the driver inserted from the through hole 37, and the front side screw hole 13 a of the mounting bracket 13 is tightened. Screw into. Thereafter, the tip end portion 9b of the strip plate 9 is inserted obliquely rearward from the through hole 37 toward the rear side 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 portion 7a of the rear mounting screw 7 is tightened by the driver 31. As a result, the shaft portion 7b of the rear side mounting screw 7 is screwed into the rear side screw hole 13b of the mounting bracket 13, and the tip portion of the strip plate 9 is inserted between the head portion 7a and the inner surface of the outer panel 23. 9b is sandwiched.

Finally, as shown in FIG. 7, the rubber stopper 35 is locked in the locking hole 33 of the inner panel 25, and the mounting work is completed. The strip plate 9 may be separated from the tip 9b at the narrowed portion 9d by twisting the insertion portion 9a, or may be left as it is without being separated and prepared for removal of the spoiler 1 at a later date.

In the embodiment having the above structure, the head 7a of the rear side mounting screw 7 can be inserted from the outer side to the inner side of the outer panel 23 through the rear side mounting hole 29 of the outer panel 23. Therefore, it is not necessary to form a large hole for inserting the head portion 7a on the inner panel 25 side, and it is sufficient to form a small hole for inserting the tip of the driver. Therefore, compared with the conventional mounting structure that requires drilling a large hole on the side of the inner panel 25 where the drilling work is difficult, the drilling work is dramatically easier and rigidity is particularly required. It is possible to prevent the decrease in rigidity due to drilling at the rear end of the trunk lid 3 as much as possible. Since the through hole 37 having a relatively large diameter formed in the inner panel 25 is formed at a position on the front side of the rear end of the trunk lid 3, the through hole 37 of the trunk lid 3 is required to be particularly rigid. There is also no loss of rigidity at the rear end.

Further, in this case, even if the rear mounting hole 29 of the outer panel 23 is formed larger than the head portion 7a of the mounting screw 7, the shaft portion 7b of the mounting screw 7 is formed in the engaging groove 9c of the strip plate 9. Since the tip portion 9b of the strip-shaped plate 9 is sandwiched between the head portion 7a of the mounting screw 7 and the inner surface of the outer panel 23 in the state of being fitted inside, the head portion 7a is the tip of the strip-shaped plate 9. The spoiler 1 can be reliably fixed in position by being supported by the inner surface of the outer panel 23 via the portion 9b.

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

In addition, since the through hole 37 as the third through hole for inserting the strip plate 9 is also used as the hole for inserting the front side mounting screw 5, a new drilling work is added. Without doing so, it is possible to easily construct a structure in which one mounting portion is positionally fixed by the two mounting screws 5 and 7.

It should be noted that the present invention is not limited to the above-described embodiment, but includes various other modified examples. For example, in the above-mentioned embodiment, the outer panel 23 and the inner panel 25 each have a double wall structure, but the 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 one or more inner panels are separated from each other.

In the above embodiment, the engaging groove 9c formed in the strip plate 9 extends in the longitudinal direction and opens at the front end. However, the present invention is not limited to this and, for example, a direction orthogonal to the longitudinal direction. May extend to the side and open to the side of the tip portion 9b.

Further, in the above embodiment, the locking hole 33 of the rubber stopper 35 is used as the second through hole, but the present invention is not limited to this, and the second through hole is not referred to as the locking hole 33. It may be provided separately.

Further, although the spoiler main body 11 and the mounting bracket 13 are separately formed in the above-mentioned embodiment, the present invention is not limited to this, and they may be integrally formed by, for example, synthetic resin molding.

[Effect of device]

 As described above, according to the structure of the mounting portion of the spoiler according to the first aspect of the present invention, the head portion of the outer panel is passed through the first through hole of the outer panel with the shaft portion of the screw screwed into the spoiler side in advance. Since it can be inserted from the outer surface side to the inner surface side, it is not necessary to form a large hole for inserting the above head part on the inner panel side, and it is small enough to insert the tip of a fastening tool such as a screwdriver. It can be limited to the formation of holes. Therefore, compared with the conventional mounting structure that requires drilling a large hole on the side of the inner panel where drilling work is difficult, the drilling work is extremely easy and, in addition, it has a multi-wall structure. As a result, it is possible to prevent the decrease in rigidity as much as possible by drilling holes in the vehicle body portion that requires particularly high rigidity. Moreover, in this case, since the relatively large-diameter third through-hole formed on the inner panel side is formed at a position away from the second through-hole position, the above-described vehicle body requiring particularly high rigidity. It does not impair the rigidity of the part.

Even if the first through hole on the outer panel side is formed larger than the head portion of the screw, the shaft portion of the screw is fitted in the engaging groove of the belt plate, and Since the tip is sandwiched between the head of the mounting screw and the inner surface of the outer panel, the head of the screw can be pressed against the inner surface of the outer panel through the tip of the strip plate. , The spoiler can be securely fixed in position.
