Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for attaching and fixing an automobile headlamp to a vehicle body.

When the lamp body of an automobile headlamp is molded from a synthetic resin material, the mounting part to the vehicle body is also molded into the same body as the lamp body, and a mounting hole is drilled in the mounting part to insert the mounting bolt. In this case, the strength of the vehicle body mounting portion is insufficient, so it is necessary to install a metal mounting collar in the mounting hole to reinforce it.

However, four car body mounting parts are usually formed, and the mounting collars installed in the mounting holes of each car body mounting part are not formed to have the same diameter in consideration of errors in molding and assembling the car body and lamp body. In other words, one of the four mounting collars installed on the vehicle body mounting part is used for the reference hole, one adjacent to this is used for the sub-reference hole, and the mounting collar for that reference hole is used for the mounting bolt. However, the mounting collar for the auxiliary reference hole must be formed into a blank hole shape or an elongated hole shape with a larger diameter than that for the reference hole, and the mounting collar for the remaining two The collar is formed into a blank hole shape or an elongated hole shape with a larger diameter than the sub-reference hole. In this way, it is necessary to prepare four types of reinforcing mounting collars to be installed at each vehicle body attachment point, depending on the four vehicle body attachment points, which makes installation work difficult and increases costs. In addition, inventory management of the mounting collars is troublesome, and the mounting collars are relatively large so that they cannot be mounted on small vehicle body mounting sections.

In view of these inconveniences and shortcomings of the conventional vehicle body mounting structure, the present invention has been developed by requiring only one type of mounting collar for each of the four vehicle body mounting points, and at the same time allowing the mounting collars to be easily installed in the mounting holes. It is an object of the present invention to provide a vehicle body mounting structure for an automobile headlamp that can improve workability and reduce costs.

An example of implementing the present invention will be described below based on the drawings.

The lamp body 1 is made of a synthetic resin material and is formed into a substantially rectangular shape from the front, and a reflector 2 and a bulb 3 are installed inside the lamp body 1, and a lens 4 is installed on the front side to constitute a headlamp A for an automobile. Then, vehicle body mounting parts 5a, 5b, 5c, and 5d are formed projecting from the same body at four corners of the lamp body 1.

The vehicle body attachment parts 5a to 5d are for attaching the light body 1, that is, the automobile headlamp A, to the vehicle body B, and are provided at four corners of the light body 1, which is formed into a substantially rectangular shape from the front, for example, on both the left and right sides of the light body 1. The upper and lower parts of the edges 1' and 1' are formed to protrude from the same body at a total of four locations, and each of the vehicle body attachment portions 5a to 5d has bolts 6 for attachment to the vehicle body.
Attachment holes 7a, 7b, 7c, and 7d are bored through which the attachment collars 8 are inserted, and attachment collars 8 are installed.

The mounting holes 7a to 7d connect the automobile headlight A to the vehicle body B.
A mounting bolt 6 is inserted through the mounting bolt 6 for fixing the lamp body to the vehicle body, and a circular shape having a diameter larger than the outer diameter of the mounting bolt 6 is bored in each of the vehicle body mounting portions 5a to 5d of the lamp body 1. The diameters of the holes on the rear side 7' facing B are all circular with the same diameter, and the diameters of the holes on the front side 7'' are formed differently depending on the location.In other words, in FIG. When the mounting hole 7a is used as a reference hole, the mounting hole 7b of the vehicle body mounting part 5b is used as a sub-reference hole, and the remaining two mounting holes 7c and 7d are used as escape holes, each hole is Attach the hole diameter of the rear side 7' facing the co-vehicle body B to the mounting bolt 6.
The diameter of the reference hole 7a on the front side 7'' is approximately the same as the outer diameter of the mounting bolt 6, and the longer diameter of the sub-reference hole 7b is the same as that of the mounting bolt 8. It is formed into a long hole shape with approximately the same diameter as the inner diameter of the
The relief holes 7c and 7d are formed in a circular shape having the same diameter as the long diameter of the elongated hole of the sub-reference hole 7b.

Therefore, a mounting collar 8 is provided in each of the mounting holes 7a to 7b.
If the mounting collar 8 is press-fitted, the mounting collar 8 will not be visible from the front side 7''.

The mounting collar 8 is formed into a circular ring shape using a metal strip that is slightly narrower than the wall thickness of the vehicle body mounting portions 5a to 5d, and is expandable by abutting both ends 8' and 8''. Which mounting hole 7a has the outer diameter?
7d are also formed to have the same diameter, and have an inner diameter approximately the same as the escape holes 7c and 7d, and are press-fitted from the rear side 7' of the mounting holes 7a to 7d. or,
This mounting collar 8 is provided with an appropriate number of latching claws 9 protruding alternately upward and downward in order to prevent it from falling off when installed in the mounting holes 7a to 7d. By forming the hook 9 in this way, the mounting holes 7a to 7d
When installing by press-fitting, it is possible to eliminate the directionality of installation and improve work efficiency. Further, by forming the butt ends 8' and 8'' of the mounting collar 8 into a combination of a mountain and a valley shape as in the illustrated embodiment, the mounting collar 8 can be press-fitted into the mounting holes 7a to 7d. It is possible to prevent the mounting collars 8 from deforming into a non-lindrical shape, and also to prevent the mounting collars 8 from intertwining with each other before being installed in the mounting holes 7a to 7d.

In this way, the present invention integrally molds car body mounting parts at four corners of a resin light body formed into a substantially rectangular shape from the front, and drills a mounting hole through which a mounting bolt passes through each car body mounting part. Since a mounting collar formed in the shape of a circular ring with the same diameter that can be expanded is installed in each of the mounting holes, the mounting collar can easily fit not only the reference hole but also the sub-reference hole and escape hole. It can be easily attached to the vehicle body as before. Therefore, it becomes possible to attach the mounting collars to the vehicle body by using only one type of mounting collar for each of the four vehicle body mounting points, which simplifies inventory management of mounting collars and reduces the work required to install the mounting collars to the vehicle body mounting sections. This improves performance and reduces costs overall.

Moreover, since the mounting collar is formed in a circular ring shape, there is no directionality with respect to the mounting hole, and the workability of installing the mounting collar on the vehicle body mounting portion is further improved.

Furthermore, the mounting collar is extremely compact and can be easily incorporated into small vehicle body mounting sections.

Therefore, the intended purpose can be achieved.
