[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary holding device for a rear lamp of an automobile.

[0002]

2. Description of the Related Art Assembling an automobile rear lamp to an automobile body is performed by attaching an automobile body mounting member 30 to the automobile body and then mounting a rear lamp stay 31 attached to the automobile rear lamp as shown in FIG. Although it is engaged with and held by the locking claw 32 of 30, the vehicle rear lamp does not have a degree of freedom with respect to its inclination. Therefore, when the vehicle rear lamp having molding distortion is assembled into the vehicle body, the misalignment is manually corrected. I had to do the installation work.

[0003]

For this reason, manpower is indispensable in the process of mounting the automobile rear lamp on the automobile body, and when attempting to automate the assembly process, the molding distortion of the automobile rear lamp and the automobile body Due to an assembly error, it was extremely difficult to install it with a robot or an automatic assembly machine that moved accurately, and automatic assembly of a rear lamp for an automobile was impossible.

[0004]

A temporary holding device for a rear lamp for an automobile according to the present invention, which has solved the above-mentioned problems, comprises:
Synthetic resin grommets in which a cylindrical spherical head is connected to the upper part of the mounting leg having a locking claw via a flange are fitted into grommet holding holes juxtaposed on the lamp mounting surface of the automobile body, respectively. The resin grommet is held in the grommet holding hole by a screw screwed into its center hole, while the rear side of the automobile rear lamp has a cross-sectional shape corresponding to the outer shape of the spherical head, and an expanded receiving portion. The elastic clips having the engaging groove portion having the are attached in parallel, and the elasticity of both the engaging groove portion of the elastic clip and the cylindrical spherical head is
The feature is that the rear lamp for an automobile is temporarily held in the automobile body by absorbing the error between the two by the engagement using the.

[0005]

In such a temporary holding device for a rear lamp for an automobile, the mounting leg is fitted into the grommet holding hole of the automobile body and the hole edge of the grommet holding hole is provided between the locking claw and the flange provided on the mounting leg. A spherical head of a synthetic resin grommet that is held on the side of the automobile body by holding it, and a rear portion of the rear lamp for the automobile that is attached in parallel on the back side of the elastic clip that has an expanded receiving portion. Since the mating groove is engaged, even if there is some molding distortion in the automobile rear lamp or there is an assembly error in the vehicle body, the error between the two will not be affected by the expansion of the engaging groove.
It is absorbed by elasticity and rotation of both the mouth portion and the cylindrical spherical head portion, and the rear lamp for a vehicle can be temporarily held on the vehicle body without requiring troublesome steps for error correction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the illustrated embodiments. Reference numeral 1 denotes a synthetic resin grommet made of a hard polyamide resin, and the synthetic resin grommet 1 is provided on the upper end of a hollow bottomed prismatic mounting leg 3 having locking claws 2 at opposing positions in an intermediate portion. A tubular spherical head 5 is formed via a flange 4 that is close to the pawl 2. The synthetic resin grommet 1 has a prismatic mounting leg 3
Is fitted into the square-shaped grommet holding hole 21 of the automobile body 20 and the edge of the grommet holding hole 21 is sandwiched between the locking claw 2 and the flange 4, so that the synthetic resin grommet 1 does not rotate and the automobile body Holds at 20. Reference numeral 6 denotes a central hole with a step portion 7 formed in the synthetic resin grommet 1. When a screw 8 is screwed into the central hole 6, the side wall of the mounting leg 3 of the synthetic resin grommet 1 swells outward to engage. The pawl 2 is expanded inward, and the synthetic resin grommet 1 is fixed to the automobile body 20.

On the other hand, 9 is an elastic clip made of polyacetal resin which is mounted in parallel with the rear lamp 22 for automobiles, and the elastic clip 9 has the spherical head 5 in cross section.
It is assumed that the mounting seat 12 with the screw hole 11 is integrally formed on the back side of the main body portion having the cross-section Ω shape which is followed by the receiving portion 10a which is expanded to the rim of the engaging groove portion 10 having the shape corresponding to There is. In the figure, 13 is an automobile body 20 and a synthetic resin grommet 1.
Is a seal rubber provided between the flange 4 and the flange 4.

With this construction, the mounting legs are formed by fitting the prismatic mounting legs 3 of the synthetic resin grommet 1 into the rectangular grommet holding holes 21 provided through the rear portion of the automobile body 20. 3 is engaged between the locking claw 2 and the flange 4, and then a screw 8 is screwed into the central hole 6 of the synthetic resin grommet 1 to inflate the side wall of the mounting leg 3 outwardly. 2 is expanded outwardly, the locking claw 2 is prevented from bending inward, the synthetic resin grommet 1 is fixedly held on the automobile body 20, and the elastic clip 9 is attached in parallel on the back surface. The rear lamp 22 for a car is
The engaging groove portion 10 of the elastic clip 9 is fitted and supported on the spherical head portion 5 of the synthetic resin grommet 1 along the rear portion thereof to be assembled.

At this time, due to the molding distortion of the automobile rear lamp 22 and the assembly error of the automobile body 20, the elasticity of the cylindrical spherical heads 5 of the synthetic resin grommets 1 arranged in parallel and the side of the automobile body 20 are juxtaposed. Engagement groove 10 of the elastic clip 9
Even if there is a slight deviation between the positions of and, the deviation between the spherical head portion 5 of the synthetic resin grommet 1 and the engagement groove portion 10 of the elastic clip 9 causes the engagement of the expanded receptacle portion 10a to continue. Groove 10 and
It is absorbed by the elasticity and rotation of both of the cylindrical spherical heads 5 described above, and the vehicle rear lamp 22 having molding distortion can be easily temporarily held on the vehicle body 20 having an assembly error, and Since it can be temporarily held by an automatic machine such as a robot having a high positioning accuracy, it can be automatically assembled by a robot or an automatic assembling machine.

[0010]

As is apparent from the above description, the present invention engages a synthetic resin grommet having a cylindrical spherical head with a grommet holding hole of an automobile body and then inserts a screw. It has good workability, can be tightened with a high torque, and has a grommet made of synthetic resin with a cylindrical spherical head, and a socket having an expanded opening with a cross-sectional shape corresponding to this cylindrical spherical head. since it is assembled by both the elasticity of the resilient clip having a coupling groove, the automobile body with the error assembling automobile rear lamps with molded strain can accurately easily temporarily held, therefore, using a robot or an automatic assembly machine Automatic assembly is also possible, which not only reduces labor costs and manufacturing costs, but also improves productivity, and uses a grommet holding hole between the locking claw and flange. This temporary holding device, which is made up of a synthetic resin grommet and an elastic clip that are held securely, does not rattle due to running vibration after fixing afterwards, so there is no abnormal noise during running, and mounting It also has many advantages such as no possibility of corrosion because the coating of the automobile body is not damaged by the temporary holding screw during the work.

Therefore, the present invention has an extremely great practical value as a solution to the problems in the automatic assembling of the conventional temporary holding device for the rear lamp of the automobile.
