Description

A kind of double-colored light guide

Technical field

The utility model relates to automobile part production technique field more particularly to automobile decoration pieces.

Background technique

Automobile is the current most common vehicles, with the continuous improvement that people sample automobile, interior design atmosphere Lamp is more and more abundant, builds automobile interior decoration harmony atmosphere.

There are two types of forms for atmosphere lamp design at present, and one is atmosphere lamp effect is realized by reflection mode, i.e. light-strip is set Meter is irradiated in another outer missing part in trim panel by leaking out one small gap, which reflects atmosphere lamp band effect Fruit.Another kind is exposed atmosphere lamp, i.e. atmosphere lamp is mounted on light transmission part, and light transmission part, which refills, is fitted on the decoration back side, Do tiny hollow out among the decoration, light-strip by the tiny hollow out irradiate come.

The first above-mentioned form atmosphere lamp cannot shine through decoration, and second of form atmosphere lamp destroys decoration table The globality in face, decorative effect be not strong.

Therefore, how existing automobile atmosphere decorative element for lamp is improved, so that it is overcome the above problem, is art technology Personnel's problem urgently to be resolved.

Utility model content

A kind of good appearance that one of the utility model is designed to provide, technique add list, and structure is reliable, at low cost Double-colored light guide.

To achieve the above objectives, a kind of the technical solution adopted in the utility model are as follows: double-colored light guide, it is characterised in that: Including electroplating plastic substrate and guide-lighting plastic basis material, the leaded light plastic basis material is set on the inside of the electroplating plastic substrate, and The electroplating plastic substrate and the guide-lighting plastic basis material are mutually rabbeted by two-shot molding process, and the leaded light plastic basis material is Transparent material；Guide-lighting slot is offered on the electroplating plastic substrate, is color chromium portion below the leaded light slot, is applied in the coloured silk chromium portion It is covered with color layers of chrome, is plated portions above the leaded light slot, is electroplate with electroplated layer in the plated portions.

Preferably, the coloured silk layers of chrome is erosion line coloured silk layers of chrome.With better texture and sense of touch.

Preferably, the leaded light plastic basis material uses PC.PC is makrolon material.

Compared with prior art, it is the advantages of technical solutions of the utility model:

1, existing plated portions, color chromium portion and guide-lighting plastics are three individual parts.This programme will be originally with Shooting Technique Independent three parts part is combined into a part, reduces installation step, avoids fit-up gap error, simplifies technique； Injection molding switching is also reduced, working hour and material have been saved.

2, four kinds of characteristic techniques (including Common platings, erosion line, color chromium and leaded light) are combined together, and build special atmosphere It encloses and distinguished perception and sense of touch.

Specifically, plated portions and color layers of chrome portion use same electroplating plastic substrate, by two-shot molding process with lead The guide-lighting plastic basis material of light slot is mutually rabbeted, and reaches reliable steady bond strength, and form uniform gap --- it leads Light slot.The high intensity and high-temperature stability of guide-lighting plastic basis material ensure that not upper plating in the plating process, indeformable, each section Between binding force do not reduce.Retain former erosion line appearance after the plating of electroplating plastic substrate, after spray paint, reaches different from plating Color sensation and sense of touch have more beautiful shape.
