本発明はテールランプの車体へのシール取付け
構造に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a structure for attaching a seal to a vehicle body for a tail lamp.
従来技術
近年、テールランプは横幅が大きくなり、また
厚さが薄くなつたためテールランプ自体の剛性が
低下してきた。従つて、従来、シール材として独
立気泡体が使用されていたため、これを介在させ

テールランプにゆがみが生じシール効果を低下さ
せていた。Prior Art In recent years, tail lamps have become wider and thinner, resulting in a decrease in the rigidity of the tail lamp itself. Therefore, since a closed-cell foam has conventionally been used as a sealant, a large amount of pressure is required to attach the tail lamp to the vehicle body through the closed-cell foam. Therefore, this pressure causes distortion in the tail lamp, reducing the sealing effect.
また、東南アジアや中近東などの高温地帯で
は、独立気泡内の気体が高温のために膨張し、テ
ールランプの剛性に勝ち、テールランプをゆがめ
シール効果が不良となる等の欠点があつた。 In addition, in high-temperature regions such as Southeast Asia and the Middle East, the gas inside the closed cells expands due to the high temperature, which overcomes the rigidity of the tail lamp, distorting the tail lamp and impairing the sealing effect.
そこで、硬度の小さい柔軟なシール材が要望さ
れていたが、この種のシール材は物理的強度も低

ルランプ取付け時にボルト座金囲りが破損し、シ
ール機能を果せ得ない欠点があつた。 Therefore, there was a need for a flexible sealing material with low hardness, but this type of sealing material also has low physical strength, so with the conventional sealing structure, the bolt washer area would be damaged when the tail lamp was installed on the car body, and the sealing material would be damaged. It had a flaw that made it unable to perform its functions.

As shown in FIGS. 2 and 3, the vehicle body mounting bolt 3 provided on the tail lamp 2 is embedded in the hole 10 of the trunk compartment 1 through the hole 6 of the packing 7 in the vehicle body (for example, trunk compartment) 1, and A sealing material 7 is installed around the entire circumference with a width wider than the seal rib width into which the hole for inserting the mounting bolt 3 is made, and is screwed from the body side. Note that Figure 1 is a perspective view of the tail lamp before installation, Figure 2 is a plan view of the tail lamp, and Figure 3 is A-A in Figure 2.
FIG. 4 is an enlarged view of the vehicle body mounting bolt 3 shown in FIG. 2 taken along line B-B'.

成されていた。 The conventional structure for attaching a seal to the vehicle body of a tail lamp is as shown in FIG.
and the surface height of the seal rib 4 are the same, and
There was little or no gap 8 between the two, and the sealing material was made of closed cell foam.

となる欠点があつた。 When the vehicle body mounting bolt 3 is inserted into the bolt insertion hole 6 and firmly tightened to the vehicle body 1, the lower surface of the sealing material 7 is compressed to the seat surface 5 of the vehicle body mounting bolt.
The gap 8 between the seal rib 4 and the seal rib 4 is pushed in and cut at the cutting end 9. As a result of this cutting, the pieces of sealing material remaining on the seat surface 5 of the vehicle body mounting bolts do not remain in a perfect shape, and as shown in FIG.
There was a drawback that the seal did not remain on the top and was shifted, resulting in poor sealing effect.

To provide a seal mounting structure that is easy to install, does not require large pressure, and has excellent workability.

7 are cutaway side views of the vicinity of a vehicle body mounting bolt showing an embodiment of the present invention, FIG. 6 showing the sealing material before cutting, and FIG. 7 showing the sealing material after cutting. The height of the seat surface 5 of the vehicle body mounting bolt is higher than the height of the seal rib 4, and the diameter of the gap 8 is 1 mm.
-10 mm, preferably 1 mm - 5 mm. If the diameter of the gap exceeds 10 mm, the nut will not work well when attaching to the vehicle body. Vehicle body mounting bolt 3
When tightened to the vehicle body 1, the height of the seat surface of the vehicle body mounting bolt is higher than the height of the seal rib 4, so
The sealing material is applied to the peripheral edge 11 of the seat surface of the vehicle body mounting bolt.
It is bent and cut when it becomes strong. but,
Due to the difference in height, the seal material on the seal rib is not damaged and the position of the seal material does not move, but is cut at the peripheral edge 11 of the seat surface of the vehicle body mounting bolt. Since the cut end 9 is separated from the seal rib, the sealing effect at the washer portion of the bolt is not reduced.

に示すようなものでもよい。 In the present invention, the term "seat surface" refers to a surface that makes it possible to set the embedding position of the mounting bolt 3 to the vehicle body in the tail lamp body 2, to ensure that the bolt adheres well to the resin, and to ensure good contact of the mounting nut to the vehicle body. For example, it may be as shown in FIG.

で、シール効果を低下させることがない。 Furthermore, it is possible to use an open-cell sealant as a sealing material, which requires less installation pressure than a closed-cell sealant, which requires less labor on the part of the operator and allows for efficient installation. . Furthermore, since the tail lamp is not distorted due to air expansion in hot regions, the sealing effect is not reduced.

あつてもよい。 The sealing material is made of rubber or synthetic resin foam, such as rubber (synthetic rubber, natural rubber), soft synthetic resin, such as polyethylene, polypropylene, ethylene, propylene copolymer, polyvinyl chloride, acrylic resin, polyurethane resin, etc. Examples include foams. Among these, foams of acrylic resin and polyurethane resin are preferred. The polyurethane foam is preferably a dimer acid polyurethane or a diene polyurethane using a hydrophobic raw material as the polyurethane raw material. Further, the synthetic resin may be added with an oil mainly composed of hydrocarbons, petroleum resin, polybutene, etc., which imparts hydrophobicity to the synthetic resin.

劣つてくる。 The foam density is preferably 0.3 to 0.02 g/mm 3 . If it exceeds 0.3g/ mm3 , the tail lamp will become distorted and it will be difficult to form a complete seal.
If it is less than mm 3 , durability will be poor and the force with which the sealing material presses between the members to be sealed will be small, resulting in poor sealing effect.

つてくる。 The hardness of the foam is preferably 40 to 1000 g/cm2, particularly 40 to 700 g/cm 2 at 50% compression hardness according to JIS6767 hardness test.
g/cm 2 is preferred. If it exceeds 1000 g/cm 2 , the tail lamp will be distorted when attached to the vehicle body, and if it is less than 40 g/cm 2 , the force with which the sealing material presses between the parts to be sealed becomes small, and the sealing effect becomes poor.

Furthermore, since it is possible to use an open cell material as the sealing material, it is flexible. Therefore, the tail lamp can be attached to the vehicle body with a small amount of force, which prevents shoulder and back pain from occurring to the worker and improves work efficiency. Further, since the sealing material is flexible, bolts can be sufficiently tightened, and the tail lamp will not be distorted due to tightening, and the number of bolts can be reduced. Furthermore, when the sealing material is an open-cell material, it has excellent effects such as not distorting the tail lamp due to gas expansion and deteriorating the sealing effect, as is the case with closed-cell material, even in hot southern regions. .
