Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wing-type synthetic resin rear spoiler for an automobile.

[Conventional technology]

A wing-type rear spoiler that is attached to the rear end of an automobile body consists of a flat spoiler body that is horizontally elongated in the vehicle width direction, and legs that support the spoiler body by protruding from the lower surface of the spoiler body. The rear spoiler is known.

This rear spoiler is generally a molded product of relatively hard synthetic resin such as FRP or polypropylene resin, or a molded product of foamed soft synthetic resin such as urethane foam.

These conventional rear spoilers had the following drawbacks.

The former relatively hard synthetic resin rear spoiler is
Although it can be molded into a sharp external shape, it lacks a soft appearance.

In addition, rear spoilers made of foamed soft synthetic resin have the disadvantage that when they have a complicated shape, such as a wing-type rear spoiler, they have poor moldability and tend to cause air pockets during foam molding, resulting in molding defects.

To this end, by making a wing-type synthetic resin rear spoiler into a split structure, an automobile synthetic resin rear spoiler (unknown) which has a soft and luxurious appearance and has excellent moldability is obtained. is proposed.

As shown in FIGS. 7 to 9, the specific structure of this synthetic resin rear spoiler 1 is such that the spoiler main body 4 and leg portions 5 are molded from hard synthetic resin, and the spoiler main body 4 is positioned at the rear of the vehicle. An elongated buffer member 6 made of foamed soft synthetic resin is attached to the edge of the side R in the vehicle width direction along the edge.

[Problem that the invention attempts to solve]

This synthetic resin rear spoiler 1 has a mounting surface 4a of the buffer member 6 formed on the spoiler body 4 in order to attach the buffer member 6 to the spoiler body 4.
The portion where the attachment surface 6a formed on the buffer member 6 and the spoiler body 4 are joined is as follows:
It tends to spread due to the pressing force when touched by a person's hands or due to differences in thermal expansion and contraction, and as a result, there is a risk that voids may be created at the bonded portion and the appearance may be impaired.

The present invention has been devised in view of the above-mentioned conventional problems, and is aimed at improving the appearance of the joint portion in a wing-type synthetic resin rear spoiler having a split structure as described above.

[Means for solving problems]

To this end, the present invention provides a wing-type synthetic resin rear spoiler with a split structure as described above, in which the buffer member has a lip portion protruding from the peripheral edge of the surface to which it is attached to the spoiler body, and this lip portion is attached to the spoiler body. It is placed in close contact with the outer surface of the spoiler adjacent to the attachment surface, and covers the attachment joint portion between the spoiler main body and the buffer member, which are divided by the lip portion.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 2 is a perspective view showing the rear part of an automobile body equipped with a synthetic resin rear spoiler according to the present invention.

1 and 3 are an exploded sectional view and a sectional view of a portion corresponding to the - line in FIG. 2, respectively.

4 is a sectional view of a portion corresponding to the line - in FIG. 2, and FIG. 5 is a sectional view of a portion corresponding to the line - in FIG. 2.

In FIGS. 1 to 5, reference numeral 1 designates a wing-type synthetic resin rear spoiler fixed to the rear end of a trunk lid 2 of an automobile by means of mounting bolts 3. As shown in FIGS.

This synthetic resin rear spoiler 1 has a flat spoiler body 4 that is horizontally elongated in the vehicle width direction, and legs 5 that protrude from the lower surface of the spoiler body 4 and support and fix the spoiler body 4, and are made of, for example, hard urethane. It is integrally molded from hard synthetic resin such as resin, FRP, and ABS resin.

A mounting bolt 3 is provided protruding from the lower end surface of the leg portion 5, and the leg portion 5 is fixed to the upper surface of the trunk lid 2 by the mounting bolt 3.

An elongated buffer member 6 made of a foamed soft synthetic resin such as urethane foam is attached to the edge of the spoiler body 4 on the vehicle rear side R along the edge in the vehicle width direction.

That is, the rear spoiler 1 is divided into a spoiler main body 4 made of hard synthetic resin and a buffer member 6 made of foamed soft synthetic resin attached to the spoiler main body 4.

This buffer member 6 is attached to the rear side R of the spoiler body 4.
The structure for attaching it to the edge will be explained.

A notch (not shown) extending in the vehicle width direction is provided at the edge of the spoiler body 4 to which the buffer member 6 is attached, and the end face of this notch is an upwardly inclined surface to form a mounting surface 4a.

The buffer member 6 has a mounting surface 6a that is a downwardly inclined surface along the mounting surface 4a, a front surface 6b that is connected to the upper surface of the spoiler body 4 that reduces the rear lift force and air resistance of the vehicle, and The cross-sectional shape is formed into an inverted triangle with the rear end surface 6c facing diagonally downward on the rear side R.

In the split structure rear spoiler constructed in this manner, the buffer member 6 includes a peripheral portion of the mounting surface 6a, for example, an intersection region between the mounting surface 6a and the front surface 6b, and the mounting surface 6a. A lip portion 6d is formed to protrude from the intersection of the rear end surface 6c and the rear end surface 6c.

The lip portion 6d protrudes along the upper and lower surfaces of the spoiler main body 4 adjacent to the mounting surface 4a, and the tips of the lip portion 6d protrude from the upper and lower surfaces adjacent to the mounting surface 4a of the spoiler main body 4. It is formed to protrude in the direction of coming into close contact with.

When the shock absorbing member 6 is attached to the spoiler main body 4 by the fixing means described later, the lip portion 6d formed on the shock absorbing member 6 is attached to the spoiler main body 4, as shown in FIG. In order to attach the spoiler body 4, the portion where the attaching surface 4a of the spoiler body 4 and the attached surface 6a of the buffer member 6 are joined can be covered.

Therefore, even if a gap is created in the bonded area due to a pressing force when touched by a human hand or a difference in thermal expansion/contraction, this gap is covered by the lip portion 6d. Therefore, since it is not exposed to the outside at all, it is possible to maintain a good appearance.

Note that the buffer member 6 shown in FIG. 6 has only a lip portion 6d that is in close contact with the upper surface of the spoiler main body 4.

Further, as shown in FIG. 5, the cushioning member 6 is installed so that a gap G is formed between both ends in the vehicle width direction and the notch end surfaces 4b at both ends of the mounting surface 4a of the spoiler body 4. Thereby, for example, the difference in thermal expansion and contraction between the buffer member 6 and the spoiler main body 4 can be absorbed.

Since this gap G is closed and covered by the lip portions 6d that protrude from both ends of the buffer member 6 along the upper and lower surfaces of the spoiler main body 4, the appearance does not deteriorate. do not have.

Furthermore, since the tip of the lip portion 6d is protruded in a direction that comes into close contact with the upper surface and the lower surface,
By being in close contact with the upper and lower surfaces, it is possible to enhance the sense of unity with the spoiler main body 4, and it is also possible to improve the overall appearance quality of the split structure rear spoiler 1.

Here, an insert 11 to which a bolt 7 is fixed is embedded in the buffer member 6 along the mounting surface 6a.

Further, the bolts 7 are attached to the mounting surface 6.
a is protruded with an appropriate interval maintained.

Further, an insert 12 having a bolt hole 8 is embedded in the spoiler body 4 along the attachment surface 4a to which the attachment surface 6a of the buffer member 6 is joined.

The bolt hole 8 is connected to the mounting surface 6 of the buffer member 6.
A hole is formed at a position corresponding to the bolt 7 protruding from the spoiler body 4, and is penetrated from the lower surface side of the spoiler main body 4 to the mounting surface 4a. Furthermore, a recess 9a having a tightening seat surface 9a for a nut 9 is formed at the peripheral edge of the bolt hole 8 on the lower surface side of the spoiler main body 4.

With this structure, in order to attach the buffer member 6 to the spoiler main body 4, the bolts 7 of the buffer member 6 are inserted into the bolt holes 8 of the spoiler main body 4, and the buffer member 6 is inserted into the mounting surface 4a of the spoiler main body 4. The spoiler can be attached by bringing the mounting surfaces 6a of the member 6 into close contact with each other and fastening nuts 9 to bolts 7 that protrude into the recesses 9a on the lower surface side of the spoiler main body 4.

In such an attached state, the nut 9 can be made difficult to see by the lip portion 6d on the lower side of the buffer member 6, so that the appearance can be further improved.

In addition, since it has a split structure, if the buffer member 6 is damaged, such as when the surface of the buffer member 6 is scratched, only the buffer member 6 needs to be replaced, which is very convenient. Even when the shock absorbing member 6 is replaced at a later date, the aforementioned effect of improving the appearance due to the lip portion 6d of the shock absorbing member 6 can be obtained.

[Effect of idea]

In the present invention, in the split-structure wing-type synthetic resin rear spoiler as described above, in order to attach the buffer member to the spoiler main body, a lip portion is formed on the buffer member to cover the joining area of these two members. The gap created at the joint site is not exposed to the outside, and the appearance can be improved.
