Abstract

The invention discloses a manufacturing method for an automobile sign capable of realizing a radar active cruise function. The manufacturing method includes obtaining a transparent plastic sign by means of manufacturing transparent polycarbonate plastics into a cambered panel with the thickness ranging from 5mm to 6mm by the aid of an injection molding machine; obtaining a transparent plastic sign with a metallic impression and a protecting layer by the aid of UV (ultraviolet) spraying materials; obtaining an indium-plated plastic sign by means of forming an indium metal film on the transparent plastic sign by an ion sputtering method; forming a seamless automobile sign finished product with uniform wall thickness ranging from 7cm to 8cm by means of assembling the indium-plated plastic sign with a plastic base; and finally detecting attenuation and obtaining the qualified automobile sign with the attenuation lower than 2.0DB (decibel) and the capability of realizing the radar active cruise function. The automobile sign has the advantages that the automobile sign has metallic luster, is penetrable by radar microwaves, can realize a function of radar measurement for front and rear automobile distances and the active cruise function, has an appearance decoration function and can meet safety requirements.

Description

technical field

[0001] The invention relates to a manufacturing method of an automobile signboard, in particular to a manufacturing method of an automobile signboard which can satisfy the functions of radar measuring the distance between front and rear vehicles and active cruise. Background technique

[0002] Car signs are widely used on various types of cars because of their appearance decoration and identification functions. At present, the production method of automobile signs is to inject the prototype of the car signs, then coat the metal layer and stick it on the body, which has the advantage of simple preparation process, but the various metals plated on the front and rear signs of the car hinder The normal emission of radar waves, as well as the uneven thickness of the produced car signs and the gaps inside, all make the microwave radar unable to transmit and receive electric waves smoothly, so the microwave radar cannot accurately measure the distance between the fr...
