Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an end rubber mounting structure for the periphery of a vehicle lamp, which is related to the improvement of the area around the lamp of a vehicle or the like.

[Conventional technology]

As shown in FIG. 4, the structure of a vehicle lamp has conventionally been such that the front surface of a lamp body 51 fixed to a vehicle body 50 is covered with a front lens 52, and a light source 5 such as a bulb is mounted.
In some cases, a rim is formed on the periphery of the front lens 52, either integrally with the front lens 52 or separate from the front lens 52. In this type of vehicle lamp, the hard front lens and rim come into contact with the painted surface of the vehicle body 50, and if the paint film is damaged by vibrations while driving, rust will form in that area, resulting in a problem that spoils the appearance. It had For this reason, generally the rim 54 and the vehicle body 5
Although there is a gap between the 0 and 0 spaces to prevent contact, not only does the appearance deteriorate, but dirt, dust, etc. can enter through this gap and accumulate on the lamp rim, etc., and may be re-used when washing the car or raining. Since this type of vehicle light fixture may flow out onto the vehicle body surface and stain it, end rubber made of extruded vinyl chloride elastomer or vulcanized rubber is used in the gap between the edge of the rim 54 and the vehicle body 50. 55 (indicated by a broken line) to reduce the gap and prevent damage to the coating film, thereby attempting to solve the above problem.

[The problem that the idea aims to solve]

However, it is quite difficult to fix this end rubber 55 to the periphery of the rim 54, and currently it is temporarily fixed to the periphery of the rim 54 with adhesive or instant adhesive, so it easily comes off, and the lamp is assembled by the car manufacturer. However, there was a problem in that the parts were detached by the time the parts were removed, resulting in poor workability during assembly.

The present invention was devised in view of the above problems, and is an end rubber for the periphery of vehicle lamps that can be reliably attached to the rim so that it will not come off during work, and that improves assembly workability. The purpose is to provide a mounting structure.

[Means to solve the problem]

In order to achieve the above object, the mounting structure of the end rubber for the periphery of a vehicle lamp according to the present invention is provided in a lamp comprising a gap-filling end rubber between the periphery of the lamp fixed to a part of the vehicle body and the vehicle body. An end formed by coextruding a groove wall corresponding to a fitting groove formed on one side of the end rubber member with an electromagnetic induction heating adhesive on the outer edge of a rim formed integrally with or separately from the front lens. The gist is to fix and integrate rubber by electromagnetic induction heating.

[Effect]

The end rubber having the above structure is fixedly integrated with the outer edge of the rim via an electromagnetic induction heating adhesive that is coextruded with the end rubber member.
There is no problem of the lamp coming off before it is assembled by an automobile manufacturer, and work efficiency during assembly is extremely improved.

Further, not only does the rim not damage the painted surface of the vehicle body, but also there is no gap between the rim and the vehicle body, so a desirable appearance can be obtained.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a mounting structure for an end rubber for the peripheral edge of a vehicle lamp according to the present invention will be described with reference to the drawings.

This example shows an automobile taillight,
Reference numeral 1 denotes a lamp body whose rear half is fitted and fixed into a mounting hole 3 drilled in a vehicle body 2, and a fitting edge 6 of a front lens 5 is fitted into a fitting groove 4 formed at the front edge of the lamp body 1.
The light source 7 such as a bulb provided in the lamp body 1 is covered by the light source 7. A rim 8 is provided around the lamp body 1, and the rim 8 has an inner edge 9 integrated with the front lens 5, and an outer edge 10 of the rim 8 and the vehicle body 2. An end rubber 11, which constitutes the mounting structure of the present invention, is provided between them. The end rubber 11 is the third
As shown in the figure, the inner wall corresponding to the fitting groove 13 for fitting into the outer edge 10 of the rim 8 formed on one side of the end rubber member 12 is made of an electromagnetic induction heating adhesive. , end rubber member 1
When extrusion molding 2, it is molded by a coextrusion molding method. The electromagnetic induction heating adhesive 14 is made by kneading a magnetic material into synthetic resin, and after molding, the fitting groove 13 is fitted to the outer edge 10 of the rim 8, and the electromagnetic induction coil is inserted as shown in FIG. By heating the electromagnetic induction heating type adhesive 14 with the electromagnetic heating jig a, it is possible to bond and integrate the entire circumference.

The material of the end rubber member 12 to be coextruded with the electromagnetic induction heating adhesive may be an olefin-based, urethane-based, vinyl chloride-based, polyester-based, vulcanized rubber-based synthetic resin elastomer, or a composite resin material thereof. preferable. In addition, the material for the rim on the adhesive side is polypropylene, ABS,
All thermoplastic synthetic resins such as acrylic, SAN, styrene, polycarbonate, and polyester synthetic resins, all thermosetting synthetic resins such as unsaturated polyester and phenolic synthetic resins, or copper, aluminum, and chromium. , all metals such as iron or alloy materials such as stainless steel can be used.

When a lamp is fixed to the car body 2 with the end rubber 11 fixed to the outer edge 10 of the rim 8, the area around the lamp comes into close contact with the car body via the end rubber 11, allowing dirt, dust, etc. to enter. In addition, since the rim 8 does not come into direct contact with the painted surface of the vehicle body 2, damage to the paint film can be prevented.

Incidentally, in the above configuration, an example has been described in which the rim 8 is configured integrally with the front lens 5, but the rim 8 may be configured separately from the front lens 5 using a metal material or a synthetic resin material. It can also be implemented in the same way.

[Effect of idea]

Since the mounting structure of the end rubber for the peripheral edge of the vehicle lamp according to the present invention is constructed as described above, the end rubber formed on the rim part is electromagnetically attached to the outer edge of the rim to prevent soil, dust, etc. from entering through the gap. Because it is fixed using an induction heating adhesive, it has excellent features such as being able to improve assembly workability by eliminating problems such as detachment by the time automakers assemble the lamp. Therefore, the practical effects after implementing the present invention are extremely large.
