Description

ACC sign

Technical Field

The utility model relates to the technical field of automobile parts, in particular to an ACC (adaptive cruise control) label.

Background

The current adaptive cruise ACC system has very strict requirements on the attenuation of radar waves, and in order to ensure the driving safety, an ACC label must ensure that the attenuation of the ACC system can be stably controlled within a required range; ACC tags are typically mounted on the front grille of a vehicle, cover the front radar of the ACC system, and require no obstruction to the transmission and reception of radar waves in the area through which they pass.

ACC signs are often required to have a three-dimensional appearance due to the design of the logo of the automobile brand, which results in uneven wall thickness of the ACC sign.

The existing ACC label mainly comprises two parts, namely a panel and a base, wherein the panel is made of transparent materials, the base is made of materials with good wave permeability, the panel and the base are both formed by injection molding, when the ACC label is produced, the position of the ACC label is larger than the thickness of other parts, when the ACC label is formed, the base is uneven in wall thickness, unevenness of the back surface is easily caused by shrinkage on the back surface of the ACC label, the inclination angles of the emitted radar waves in the horizontal direction and the vertical direction can be influenced, the radar waves can be refracted by steps in the unevenness area and exceed the required reference range, and therefore the risk of potential safety hazards can be caused.

an ACC tag comprises an outer layer, an intermediate layer and an inner layer, wherein the outer layer, the intermediate layer and the inner layer are sequentially arranged, and the intermediate layer and the inner layer are both formed by injection molding; the middle layer is provided with a car logo structure and a leveling part, the car logo structure is fixedly connected with the outer side layer, and the inner side layer is fixedly connected with the leveling part.

Through the scheme, in the cooling process after the injection molding of the intermediate layer, the intermediate layer has uneven wall thickness, and the shrinkage conditions at different positions cause the concave part of the flattening part of the intermediate layer (namely the back surface of the intermediate layer) to cause uneven back surface. Through the interior layer of moulding plastics on the basis in intermediate level afterwards, because the wall thickness on interior layer is comparatively even, the shrink at the back on interior layer is comparatively even, and interior layer is used for making the whole more level and smooth in back of ACC sign, has improved the roughness of base, has guaranteed the radar penetrability, has improved the product security.

As a further improvement of the above technical solution, the intermediate layer and the inner layer are made of AES material.

Through the scheme, the AES material is strong in wave permeability and low in price, production cost can be effectively reduced, and radar penetrability can be guaranteed.

As a further improvement of the above technical solution, the outer layer is made of PC material.

Through above-mentioned scheme, the transparent demand of outside layer can be satisfied to the PC material has certain wave-transparent performance for the PP material, is applicable to the preparation of ACC sign.

As a further improvement of the above technical solution, a surface of the outer layer remote from the intermediate layer is covered with a protective paint layer.

Through above-mentioned scheme, the outside layer can be protected to the protective paint layer, improves the resistant scratch resistance and the high temperature resistance on the bat printing layer and the PVD layer of ACC sign.

The utility model has the beneficial effects that: the inside layer is used for making the whole more level and smooth in the back of ACC sign, has improved the roughness of base, has guaranteed the radar penetrability.

The utility model is used in the technical field of automobile parts.
