Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to an improvement in the structure of a front spoiler that is attached to the lower end of a front bumper in order to improve aerodynamic characteristics when an automobile is running at high speed.

[Prior art]

The first type of front spoiler for automobiles.
As shown in the figure, there is a type in which a front spoiler 1 made of urethane elastomer and having a shape that protrudes forward and has an angle to scoop up air is attached to the lower end of a front bumper cover 2. Both the front spoiler 1 and the front bumper cover 2 are made of synthetic resin, so as shown in FIG. It is then tightened and fixed with a bolt 6. Reference numeral 7 in FIG. 2 indicates a clip. Therefore, when assembling the front spoiler 1 to the lower end of the front bumper cover 2, the worker supports the front spoiler 1 from below with his hands, aligns the lower retainer 5 in this state, and then tightens the bolts 6. However, as mentioned above, the front spoiler 1 is made of a soft material such as urethane elastomer and is long in the width direction of the vehicle body, so when the worker holds it with his/her hand, it bends in an arched manner. The front spoiler 1 will be in a curved state, making it difficult to set it on the front bumper cover 2 and to align the tightening holes with the front bumper cover 2.Furthermore, there is a risk that the front spoiler 1 will fall off during the work. The problem is that it can damage the. To solve this problem, it is conceivable to provide a large dedicated jig for assembling the front spoiler, but this poses new problems in that it is cumbersome to handle and increases costs.

[Purpose of invention]

This idea was made in view of the above-mentioned conventional problems, and allows the front spoiler to be assembled easily, quickly, and reliably without using a special assembly jig. The purpose is to provide a front spoiler structure for an automobile.

[Structure of the idea]

This invention provides a front spoiler structure for an automobile, which includes a resin front spoiler that is tightened and fixed together with a lower retainer at the lower end of a front bumper by bolts, and a front spoiler that protrudes in the direction of the lower retainer on a contact surface of the front spoiler with the lower retainer. a plurality of ribs integrally formed at appropriate intervals; a plurality of mounting holes formed on the lower retainer corresponding to the ribs and fitted into the ribs; and a plurality of mounting holes formed on the front spoiler and fitted with the ribs. a locking part that elastically fits and holds the lower retainer in a state where it is fitted to the rib;
The above object is achieved by providing a hook formed at the upper end of the front spoiler and hooked onto the front bumper side member.

[Effect of invention]

In this invention, the lower retainer is fitted into a rib integrally formed to protrude from the front spoiler, and this lower retainer is fixed to the locking part, and is made integral with the front spoiler by a clip, thereby increasing the rigidity. This increases the curvature during assembly, and furthermore, a hook provided on the front spoiler side is hooked onto the front bumper side member to prevent it from falling off.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, as shown in FIGS. 3 to 8, a front spoiler 11 made of urethane elastomer is secured together with a lower retainer 15 by bolts 16 to the lower end of a front bumper cover 12 of a front bumper (not shown). In the front spoiler structure for an automobile, a plurality of ribs 18 are integrally formed on the contact surface of the front spoiler 11 with the lower retainer 15, projecting toward the lower retainer 15 and spaced at appropriate intervals.
A plurality of mounting holes 19 are formed in the lower retainer 15 to correspond to the ribs 18 and are fitted into the ribs 18, and a plurality of mounting holes 19 are formed in the front spoiler 11 and the mounting holes 19 are fitted into the ribs 18. A locking part 20 that elastically fits and holds the lower retainer 15 in the suspended state, and a hook part 21 formed at the upper end of the front spoiler 11 and hooked to the front bumper cover 12. It is. The locking part 20 of the front spoiler 11 is formed at the lower part of the rear end of the front spoiler 11, as shown in an enlarged view in FIG.
The lower retainer 15 pushed in from A is elastically held. The rib 18 is formed so that the attachment hole 19 of the lower retainer 15 is fitted into it when the lower retainer 15 is pushed into the locking portion 20 (see FIG. 5). Further, as shown in FIG. 5, the lower retainer 15 is fitted into the rib 18 and is integrally attached to the front spoiler 11 by pushing the clip 17 into the rib 18. Ready to be installed. Here, the root portion of the rib 18 is higher than the plate thickness of the lower retainer 15, and the clip 17
The large-diameter stepped portion 18A is larger than the mounting hole 17A, thereby preventing the clip 17 from being pushed into the rib 18 too much. In this way, the front spoiler 11 has the lower retainer 15 held in the locking part 20 and is integrally attached to the rib 18 by the clip 17, thereby increasing the overall combined rigidity. In the state shown in FIGS. 7 and 8, the front bumper cover 1
The hook part 21 is hooked into the hook hole 22 formed on the second side, and temporarily fixed to the lower end of the front bumper cover 12. In this state, as shown in FIG. 6, the front spoiler 11 is fixed to the front by inserting the bolt 16 from below the lower retainer 15, attaching the upper retainer 14 to it from the opposite side, and screwing it into the nut 23. Finally, it is tightened and fixed to the lower end of the bumper cover 12. Therefore, in this embodiment, the combined rigidity of the front spoiler 11 can be increased by holding the lower retainer 15 in the locking part 20 of the front spoiler 11 in advance and connecting them together. front spoiler 1
When lifting the front bumper cover 1 to the lower side of the front bumper cover 12, it is less likely to curve into an arch, and alignment with the front bumper cover 12 side is easy. Also, at this time, the front spoiler 11 is tightened and fixed with the bolts 16 and nuts 23 after the hook portion 21 is hooked into the hook hole 22 on the front bumper cover 12 side, so that the front spoiler 11 is not assembled. There is no chance of it falling off over time, thus preventing it from being damaged. Further, by temporarily fixing it to the front bumper cover 12 side using the hook portion 21, the assembly work becomes easier. Also, of course, no special assembly jig is required. In the above embodiment, the lower retainer 15 is held by the locking part 20 and connected to the front spoiler 11 by the clip 17, but the holding force of the lower retainer 15 is sufficient by the locking part 20 and the rib 18. If so, the clip 17 is not necessarily necessary. Further, in the above embodiment, the front spoiler 11 is attached to the lower end of the front bumper cover 12, but the present invention is not limited to this, and the front spoiler 11 is attached to the front bumper including the front bumper cover 12. Therefore, the front spoiler 11 may be directly attached to the front bumper.

[Effect of the idea]

Since the present invention is configured as described above, the rigidity of the front spoiler is increased to suppress bending during assembly work, and by temporarily fixing it to the front bumper side, a dedicated assembly jig can be used. This has excellent effects in that the front spoiler can be prevented from falling off during work, and the assembly work can be made easier, faster, and more reliable.
