Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a spoiler attachment structure that is attached to a vehicle body side member such as a bumper or fender of an automobile.

2. Description of the Related Art Generally, a spoiler made of rubber or synthetic resin is fixed to the end of a vehicle body side member such as a fender or a bumper of an automobile 1 shown in FIG.
For example, in the illustrated example, 2 indicates a front spoiler fixed to the front bumper, 3 indicates a side spoiler, and 4 indicates a rear spoiler fixed to the rear bumper. FIG. 4 shows an example of the above configuration in which the rear spoiler 2 is attached to the end 5a of the rear bumper 5. As shown in the figure, the flange 2a of the rear spoiler 2 is brought into contact with the end 5a of the rear bumper 5. The machine bolts 6 and spring nuts 7 are used to screw and fix the two together. Usually, the other ends 2b and 2c of the rear spoiler 2 are simply brought into contact with the surface of the rear bumper 5, and further, the other ends 2b and 2c are attached to the rear bumper 5 using double-sided tape or the like.
In some cases, adhesives are also used. In addition, a weld bolt 10 is installed near the lower end of the rear spoiler 2.
Hole 5 made in rear bumper 5 by standing 10
An example is also known in which the bolts are fitted into the holes d and 5d and screwed and fixed using a nut 11. Although the above embodiment shows an example of the connection structure between the rear spoiler 2 and the rear bumper 5, it is obvious that substantially the same structure can be adopted for other side spoiler and rear spoiler mounting structures. be.

Problems to be Solved by the Invention However, in such a conventional automobile spoiler mounting structure, the spoiler 2 and vehicle body side members such as the rear bumper 5 are basically connected to the tapping screw 6 and the weld bolt 10. ,10
Since the rear spoiler 2 is only screwed and fixed with equal screw members, the mounting strength of the rear spoiler 2 is insufficient, and the other ends 2b and 2c of the rear spoiler 2 may lift up from the vehicle body side member and vibrate, or heat shrinkage may occur. There was a problem that deformation occurred.

Therefore, the present invention solves the problems that conventional automobile spoiler mounting structures have, improves the mounting strength between various spoilers and vehicle body side members, and prevents vibrations or thermal deformation from occurring. The present invention provides a mounting structure for an automobile spoiler.

Means for Solving the Problem One end of a spoiler made of rubber or synthetic resin is screwed and fixed to the end of a vehicle body side member such as an automobile bumper or fender, while the other end of the spoiler is screwed and fixed to the end of a vehicle body side member such as an automobile bumper or fender. A plurality of bosses are erected at the portions that come into contact with the bosses, a plurality of holes are formed in the vehicle body side member corresponding to the erected positions of the bosses, and the bosses are fitted into the holes to form the holes. The boss and the vehicle body side member are screwed together and fixed using an open retainer and a screw member.

Function One end of the spoiler is screwed and fixed to the end of the vehicle body side member, while a plurality of bosses erected at the other end of the spoiler are fitted into holes of the plurality of vehicle body side members, Since the spoiler is screwed and fixed via the perforated retainer, the spoiler is supported and fixed to the vehicle body side member at multiple locations while being prevented from vibration and deformation.

Embodiments Hereinafter, a mounting structure for an automobile spoiler according to the present invention will be described in detail with reference to the drawings, with the same reference numerals attached to the same components as in the conventional structure. In the configuration shown in FIG. 1, 5 indicates a part of the rear bumper, and 2 is a rear spoiler fixed to the rear bumper 5. End 5 of rear bumper 5
Holes 5b, 5b are opened in the rear spoiler 2, and holes 2d, 5b are opened in the flange 2a of one rear spoiler 2.
2d is open, and the flange 2a of the rear spoiler 2 is brought into contact with the end 5a of the rear bumper 5, and the two are screwed and fixed using a tapping screw 6 and a spring nut 7. Furthermore, the other end of the rear spoiler 2 can be placed at any desired position.
In the illustrated example, a plurality of bosses 7, 7, . . . are provided upright near the flange 2e, and screw holes 7a, 7a, . Further, the rear bumper 5 has a plurality of holes 5c, 5c formed at positions facing the bosses 7, 7, and the bosses 7, 7 are fitted into the holes 5c, 5c. Using the perforated retainer 8 and screw members 9, 9... from the back surface of the rear bumper 5, the perforated retainer 8 is attached to the bosses 7, 7... of the rear spoiler 2.
Screw it into place. FIGS. 2A and 2B are cross-sectional views showing the main parts of the above-mentioned screwed fixing portion. In the case of the illustrated example, weld nuts 10, 10 are erected near the lower end of the rear spoiler 2, and the rear bumper 5 is
The nut 11 is fitted into the holes 5d, 5d opened in the
By screwing and fixing using screws, it is possible to further improve the ease of installation.

According to this mounting structure of the rear spoiler 2,
Since the rear spoiler 2 is supported and fixed to the rear bumper 5 at multiple locations, the attachment strength of the rear spoiler 2 is increased, and a structure is provided that has vibration damping properties and does not cause thermal deformation.

Effects of the Invention As explained in detail above, according to the mounting structure for an automobile spoiler according to the present invention, one end of the spoiler made of rubber or synthetic resin is screwed and fixed to the end of a vehicle body side member such as an automobile bumper or fender. On the other hand, a plurality of bosses are erected at the other end of the spoiler and at a portion that abuts the vehicle body side member, and a plurality of holes are formed in the vehicle body side member corresponding to the erected positions of the bosses. Then, the boss is fitted into the hole and the boss and the vehicle body side member are screwed and fixed using a perforated retainer and a screw member, so that the following effects can be obtained. That is, since various spoilers are supported and fixed to the vehicle body side member at multiple locations, the attachment strength of the spoiler to the vehicle body side member is increased, and deformation due to lifting phenomenon or heat shrinkage of the spoiler is prevented. This eliminates the need for reinforcing core metal inside the flange, reducing manufacturing costs. Therefore, it is possible to eliminate accidents such as the spoiler rattling or falling off due to vibrations during driving, and it is also possible to maintain a good appearance for a long time.
