Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a mounting structure for an air spoiler provided at the lower part of a bumper, which is used in the technical field of vehicle body equipment.

(Prior Art) When a car is running, the front end of the car body lifts up due to the influence of a headwind, which causes a problem that impairs maneuverability. Therefore, air damp spoilers have been used in the past to prevent this kind of lifting phenomenon (for example,
-Refer to Publication No. 113279).

(Problem to be solved by the invention) However, since this air spoiler is integrally molded from synthetic resin material, the corner radius of the air spoiler may vary depending on the model change of the car or the difference in car type. If there is even a slight difference, it is necessary to prepare a wide variety of expensive molding molds, which increases production costs. Therefore, even if an air spoiler is manufactured by extrusion molding which does not require a molding die, there is a problem in that this molding method cannot be adopted because of the curved corners.

In view of these conventional problems, the present invention provides an automobile air spoiler mounting structure that reduces production costs by making the air spoiler made of synthetic resin material into a shape that can be extruded. With the goal.

(Means for Solving the Problems) In order to achieve the above object, the solving means of the present invention provides a plurality of inwardly openings along the longitudinal direction of the airdam spoiler at the bumper mating portion at each corner of the airdam spoiler. Notches are formed, and fastening parts are formed on the sides of the notches located at both ends of the notches at each corner. Then, a bracket extending over the plurality of notches is brought into contact with the lower surface of each corner of the airdam spoiler and is fastened to the bumper by a fastener via the fastening part, so that the airdam spoiler is connected to the bracket and the bumper. Assume that it is being held in place.

(Function) Accordingly, in the present invention, the airdam spoiler can be easily curved and deformed along the corner portions of the bumper by the plurality of notches opening inward formed in the bumper mating portions at each corner portion. can be adapted. Moreover, since the airdam spoiler is held between the bumper and the bracket and fastened with the fasteners through the fastening parts on the sides of both ends of the plurality of notches, the corner parts of the airdam spoiler are firmly fixed. Ru.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. Note that in this explanation, the left direction in FIGS. 1 to 3 is referred to as outside, and the right direction is referred to as inside.

FIG. 1 shows a mounting structure 3 of an airdam spoiler 2 provided at the lower end of a front bumper 1 of an automobile.
The front bumper 1 includes a shock absorbing member A, a reinforcing member R, and a bumper bracket B, and is fixed to a vehicle chassis C.

To explain the mounting structure 3 with reference to FIGS. 2 and 3, at each corner portion 4 of the air spoiler 2 where it meets the front bumper 1,
Along the longitudinal direction of the air spoiler 2, a plurality of notches 6 each having an open opening 5 opening inward;
6... (4 pieces in the figure) are formed, and a fastening part is formed on the side of each of the notches 6, 6... located at both ends of the plurality of notches 6, 6... in each corner portion 4. A mounting hole is formed. A bracket 7 that spans the plurality of notches 6, 6, etc. is abutted on the lower surface of each corner 4 of the air spoiler 2, and a fastener 8 made of a bolt, nut, etc. is inserted through the mounting hole. An air spoiler 2 is fastened to a front bumper 1 and is held between a bracket 7 and the front bumper 1.

In its cross-sectional shape, the airdam spoiler 2 includes a base plate 9 that is joined to the lower end flat plate portion 1a of the front bumper 1, and extends from the outer edge of the base plate 9 at an angle outward. It comprises a substantially U-shaped outer wall portion 10 that overhangs toward the outside, and an inner wall portion 11 that extends diagonally downward inward from the inner edge of the substrate portion 9, and is made of synthetic resin material or the like. It is formed into a long length by extrusion molding, and after being cut to a standard length determined by the vehicle type, etc., the necessary number of notches 6 are formed at the positions of the corner portions 4. the number of the notches 6;
The planar shape, notch depth D, etc. are set in consideration of the radius of the corner portion 4 and the hardness of the synthetic resin material.

The bracket 7 is formed into a curved shape along the corner portion 4 by press working using a steel material or the like, and has a main body that comes into contact with the lower surface of the base plate portion 9 of the air damp spoiler 1 in its cross-sectional shape. portion 12, and a locking rib portion 13 extending diagonally downward inward from the inner edge of the main body portion 12.
It consists of. The locking rib portion 13 is formed so as to be tightly bonded to the outside (left side in FIG. 2) of the air spoiler inner wall portion 11.

Next, the operation of this embodiment will be explained.

The air spoiler 2 can be easily curved and deformed along the shape of the corner portion of the front bumper 1 by the plurality of notches 6, and can be adapted to the shape without difficulty. Furthermore, even if the corner portions 4 of the airdam spoiler 2 are strongly fastened by the fasteners 8 on both sides of the plurality of notches 6, the inner wall portion 11 of the airdam spoiler 2 will not fit into the locking rib portion of the bracket 7. 13 and there is no risk of it slipping out, the corner portion 4
has a strong mounting structure.

(Effects of the Invention) With the above configuration of the present invention, the air spoiler can be adapted to various corner shapes of the bumper by forming cutouts in the extruded product. Therefore, if the curved shape of the bumper corner changes depending on the car model, etc., it is only necessary to replace only the bracket with one of the same curved shape, which not only significantly reduces manufacturing costs, but also reduces the need for air dams at the corner. The installed state of the spoiler has the effect of being firmly held by the bracket.
