Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a reflector used in automobile lighting equipment such as automobile headlamps.

<Prior Art> Recently, as lighting fixtures have become smaller and thinner, reflecting mirrors have increasingly been molded from resin materials.

However, when a reflecting mirror is molded using the injection molding method using FRP material, gas from molding accumulates at the end of the mounting stay, which tends to cause welds. That is, as shown in Fig. 5, when FRP material is used for injection molding, the mounting stay a
, especially the mounting hole d in the opening c where there is no side wall b
Gas f during molding tends to accumulate in the upper end e of the opening, causing a weld to form.As a result, the part e tends to become extremely fragile, resulting in a high rate of defective products.

<Problems to be solved by the invention> The present invention was made in view of these conventional drawbacks, and even if FRP material is molded using the injection molding method, the rim of the mounting hole of the mounting stay is It is an object of the present invention to provide a reflector for an automobile lamp that can maintain sufficient strength and reduce the rate of defective products during molding, thereby reducing costs.

<Means for solving the problem> The reflector of the present invention automobile light that achieves the above purpose is a reflector molded using FRP material by the injection molding method, and a reinforcing rib is provided at the upper end of the mounting hole mouth edge of the mounting stay. It is characterized by having two protrusions formed on the same body.

<Example> Hereinafter, an example of implementing the present invention will be described based on the drawings.

The reflecting mirror 1 is molded into a desired shape by injection molding using FRP material, and a plurality of (usually three) mounting stays 2 are formed protruding from the same body on the back side thereof.

Further, a protrusion 8 for engaging a pressure spring 7 for press-supporting the bulb socket 6 is integrally formed on the edge 5' of the bulb mounting hole 5 of the reflecting mirror 1.

Therefore, the pressing spring 7 is movably engaged by the screw head 9 and the protrusion 8 fixed to the mouth edge 5' of the valve mounting hole 5, and the operating portion 7' is attached to the mouth edge 5' of the valve mounting hole 5. A hook portion 10 formed integrally and protrudingly on the edge
It can be hung and removed freely.

The mounting stay 2 is a member for attaching the reflector 1 to the light body by connecting the optical axis adjustment rod and fulcrum support rod supported by the light body (not shown). It is usually formed protruding from the same body in three places on the side. This mounting stay 2 is formed into a box shape with a part of the four peripheral walls 21 having an opening 22, and has a mounting hole at the upper end for inserting and connecting the optical axis adjustment rod and fulcrum support rod supported by the lamp body. 23 is formed with an opening. That is, the mounting hole 23 is formed between the upper end 21' and the opening 22 of the four peripheral walls 21 constituting the mounting stay 2.
The upper wall portion 22a is composed of the upper wall portion 22a. Then, a reinforcing rib 3 is integrally formed to protrude from the upper end of the mouth edge of the mounting hole 23, specifically, from the upper end of the upper wall portion 22a of the opening 22 constituting the mounting hole 23.

The reinforcing rib 3 is formed at the upper end of the upper wall portion 22a of the opening 22 constituting the mounting hole 23 of the mounting stay 2, and protrudes upward (towards the rear of the reflector) along the upper wall portion 22a in a gentle arc shape. It will be done.

The reinforcing rib 3 is molded simultaneously with the reflecting mirror 1 and its mounting stay 2 by an injection molding method using FRP material. At that time,
Gas 4 during molding passes through the upper wall portion 22a of the opening 22 forming the mounting hole 23 of the mounting stay 2 and is confined within the reinforcing rib 3.

<Effects of the invention> Since the reflector of the automotive lamp of the present invention is constructed in this way, the gas during molding passes through the upper wall of the opening that constitutes the mounting hole of the mounting stay and is confined within the reinforcing rib. I end up getting beaten up. Therefore, gas will not accumulate on the edge of the mounting hole of the mounting stay and welds will not occur, and together with the presence of the reinforcing ribs, the edge of the mounting hole of the mounting stay can maintain sufficient strength. , it becomes possible to reduce the rate of defective products during molding and reduce costs.

Thus, the intended purpose can be achieved.
