Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an automobile spoiler.

(Prior Art) Conventionally, a spoiler for a vehicle such as a rear spoiler attached to a rear portion of a vehicle body to prevent the vehicle body from being lifted up when the vehicle travels at high speed is well known. Further, such a vehicle spoiler body using a resin molded body is known, for example, from Japanese Utility Model Laid-Open No. 61-46289, and the above-mentioned publication describes the joint between the spoiler body and the vehicle body. It is disclosed that a sheet-shaped interposer is interposed between them.

(Problems to be solved by the invention) By the way, when an interposer is interposed between the spoiler body joint and the vehicle body as described above, the joint surface of the spoiler body and the vehicle body outer surface are three-dimensional curved surfaces. In the case where the interposer body is joined to the outer surface of the spoiler body so that the outer periphery of the interposer body is aligned with the outer periphery of the joint surface formed in the three-dimensional concave curved surface of the spoiler body, as shown in FIG. 21 wrinkles easily occur inside the joint, and it is not possible to obtain a tightly bonded joint over the entire surface.As a result, sufficient adhesive strength cannot be obtained and the joint of the spoiler body rises from the outer surface of the vehicle body, resulting in poor appearance. There is a problem.

In view of the above problems, the present invention provides a spoiler for an automobile that does not cause wrinkles in an interposer interposed between the spoiler main body and the outer surface of the vehicle body and that can obtain a proper splicing state without rising. The purpose is to provide.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention comprises a spoiler body and a sheet-like interposer interposed between a joint surface of the spoiler body with respect to the vehicle body and the vehicle body. In a spoiler for an automobile in which the joint surface is formed into a three-dimensional concave curved surface so as to correspond to the three-dimensional convex curved portion of the vehicle body, in the sheet-shaped interposer, along the longitudinal direction of the joint surface. And a slit whose at least one end is closed is formed.

(Operation) According to the above configuration of the present invention, when the joint surface of the spoiler body is formed into a three-dimensional concave curved surface corresponding to the outer surface of the vehicle body, a sheet-like interposition is provided on the outer periphery of the joint surface of the spoiler body. Even if the outer circumferences of the body are joined together, the bending that occurs in the sheet-like interposition body at that time is absorbed by the slits, so wrinkles do not occur in the sheet-like interposition body, and as a result, the spoiler body A joint state in which the joint surface is closely attached to the outer surface of the vehicle body through the sheet-like interposition body is obtained, sufficient adhesive force is obtained between them, and the joint portion does not rise and a poor-looking joint state occurs. Can be reliably prevented.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 8.

In FIG. 7, reference numeral 1 is a vehicle body of a cab-over type automobile, and its rear surface is constituted by a lift-opening type back door 2. At the upper end of the back door 2, a plane that projects into the air flow that has flowed along the upper surface of the roof of the vehicle body 1 and guides part of the air flow so that it flows along the rear surface of the vehicle body 1, that is, the back door 2. A spoiler 3 having a U-shape is attached.

As shown in FIGS. 8 and 3 to 6, the spoiler 3 is provided with a spoiler main body 4 made of a blow molded synthetic resin hollow molded body. A lamp unit 5 having a built-in braking indicator lamp and the like is mounted on the rear portion of the central portion in the direction. Further, at both end portions of the spoiler body 4, joint portions 6 with the back door 2 are formed which are bent toward the back door 2 side and extend downward. The joint surface 7 of the joint portion 6 facing the outer surface of the back door 2 has respective curvatures in three directions indicated by arrows a, b and c in FIG. 8 in accordance with the curved surface of the outer surface of the back door 2. It is formed into a three-dimensional curved surface. A mounting bolt 8 for fastening and fixing the back door 2 is embedded in the upper portion of the joint portion 6 so as to project from the joint surface 7. Also, at the bottom of the joint 6, a third
As shown in FIG. 4 and FIG. 4, a fastening recess 9 is formed, and the fastening recess 9 is configured to be fastened and fixed to the back door 2 by a mounting bolt (not shown) which penetrates the bolt hole 9a.

Between the joint surface 7 of the spoiler body 4 and the outer surface of the vehicle body 1,
As shown in FIG. 1 and FIG. 2, a slight molding error between the joint surface 7 and the outer surface of the back door 2 is absorbed to bring them into close contact with each other, and a seal around the mounting bolt 8 is secured. Further, in order to further disperse the local load and avoid stress concentration, an elastic sheet-shaped interposer 10 is interposed.

The hollow space 11 in the spoiler body 4 extends to a substantially middle portion in the vertical direction of the joint portion 6, and the lower portion thereof is solid, as shown in FIGS. 5, 6, and 2. . The joint portion 6 is formed with a water draining hole 12 opening from the lowermost end of the hollow space 11 or a position in the vicinity thereof to the joint surface 7 side, and the sheet-like interposer 10 has a water draining hole 12 formed therein. A slit 13 for draining water, which extends downward from the corresponding position and is opened to the outside in the vicinity of the lower end of the peripheral edge of the joint 6, is formed.
Instead of the slit 13, a groove having a thin wall may be used. In the illustrated example, the slit 13 is bent outward near the lower end thereof, and the open end is directed outward in the vehicle width direction.

Further, the sheet-like interposer 10 has an opening 14 corresponding to the mounting bolt 8 and an opening 15 corresponding to the fastening recess 9. In the illustrated example, the opening 15 and the slit 13 are continuously formed. A slit 16 is formed in the upper portion of the slit 13 along the longitudinal direction of the joint surface 7.

Further, when the back door 2 is lifted upward as shown in FIG. 7, rainwater collects between the outer surface of the back door 2 and the trailing edge of the joint portion 6 of the spoiler body 4, which causes the back door 2 to move. A drainage passage 17 is formed from the rear edge of the upper portion of the joint 6 to the front edge side so as not to fall to the front when closed. This drainage passage 17 has a joint surface 7
The groove 18 is formed by the groove 18, and the groove portion 19 is formed by bending the corresponding portion of the sheet-shaped interposer 10 so as to fit into the groove 18.

In the above configuration, the spoiler body 4 is attached to the back door 2
When it is mounted on the back door 2, the adhesive is applied to the joint surface 7 and the sheet-like interposer 10, and the sheet-like interposer 10 is interposed to join to the outer surface of the back door 2. The spoiler body 4 is fastened and fixed by a mounting bolt (not shown) inserted through the bolt hole 9a, but when the outer periphery of the sheet-like interposer 10 is joined to the outer periphery of the joint surface 7, the spoiler body 4 is joined.
Since the joint surface 7 and the outer surface of the back door 2 are formed into a three-dimensional curved surface, the deflection that is likely to occur inside the sheet-like interposer 10 can be absorbed by the slits 13 and 16, so that the sheet Wrinkles do not occur on the sheet-like interposer 10, and the joint surface 7 and the outer surface of the back door 2 can be brought into close contact with each other via the sheet-like interposer 10, and sufficient adhesive force can be obtained and the spoiler body 4 It does not come up and looks good.

Further, even if rainwater enters the spoiler body 4 from the mounting portion of the lamp unit 5 of the spoiler body 4 during rainy weather or when washing the car, the rainwater, etc. will be as shown by arrows in FIGS. 3 and 4. , Flows down through the bottom of the hollow space 11 to the lowermost end of the hollow space 11 in the joints 6 on both sides, and passes through the drain hole 12 to the outside of the joint surface 7 as shown by the arrow in FIG. Spilled,
Further, it passes through a drainage slit 13 formed in the sheet-shaped interposer 10 and is reliably discharged along the outer surface of the back door 2. Moreover, on the appearance, there is only an opening in the vicinity of the lower end edge of the joint portion 6 where a part of the peripheral edge of the sheet-like interposer 10 is absent, and there is no drain hole on the outer surface of the spoiler body 4. So it looks good.

Further, when the back door 2 is lifted upward as shown in FIG. 7 in case of rain or the like, a recess formed between the outer surface of the back door 2 and the rear edge of the joint portion 6 of the spoiler body 4, that is, Rainwater collects in the area A shown by the diagonal lines in FIG. 8, but since this rainwater is discharged forward through the drainage passage 17, the collected water overflows toward the front when the back door 2 is closed, and It does not cause any troubles such as

Although the spoiler 3 is attached to the upper end of the back door 2 in the above embodiment, the spoiler 3 may be attached to an appropriate place such as a bend in the rear end of the vehicle body 1, if necessary. It can also be applied to other than the rear spoiler.

(Effect of the Invention) According to the spoiler for an automobile of the present invention, when the joint surface of the spoiler body is formed into a three-dimensional concave curved surface corresponding to the outer surface of the vehicle body, the seat is formed on the outer periphery of the joint surface of the spoiler body. Even if the outer circumferences of the sheet-like interposer are joined together, since the bending that occurs in the sheet-like interposer at that time is absorbed by the slits, wrinkles do not occur in the sheet-like interposer, and As a result, the joint surface of the spoiler body is closely adhered to the outer surface of the vehicle body through the sheet-shaped interposer, sufficient adhesive force is obtained between them, and the joint portion does not float and a poor-looking joint state occurs. It has a great effect in practical use, such as being able to reliably prevent
