Description

The present invention relates to a vehicle wheel having a display unit.

A vehicle wheel made of a light alloy such as an aluminum alloy has a display unit for displaying stylized / decorated characters, a logotype of a character string, a design figure, and the like. There is a technique of Patent Document 1 as a conventional technique in which this display portion is engraved.
The technique of Patent Document 1 is a part of a painted portion of a disc or rim including spokes after the entire wheel is painted in a light alloy vehicle wheel including a rim in an integral or split structure and a disc having a plurality of spokes. By cutting the coating film and the base metal by machining, a display unit including a concave or convex logo portion consisting of letters, figures, symbols, etc. is formed while exposing the metal surface, and the logo on the display portion is formed. An engraved portion is formed on the exposed metal portion other than the portion or the logo portion so that the surface is a continuous surface of the uneven streaks, leaving the blades of the machine tool. A transparent layer is formed by applying a colored or colorless clear paint, and the engraved part emphasizes the three-dimensional effect by utilizing the refraction and reflection of light due to the uneven streaks of the base metal and the layer thickness of the transparent layer. The present configuration is provided (claim 1).

Japanese Patent No. 6153437

In the above-mentioned conventional technique, uneven streaks are continuously processed by leaving the blades of a machine tool on the exposed metal portion of the wheel, and the uneven surfaces of the plurality of uneven streaks become light reflecting surfaces to change the light reflection direction. Since each uneven streak can be engraved by continuously moving the blade along the surface of the exposed metal part, it is easy to process, but each uneven streak has both convex and concave surfaces in the direction of blade movement. It has a streak (long line shape) light reflecting surface along the line, and the light reflection direction is constrained by the line shape, and the light reflection display effect is unsatisfactory because it is simple.

The transparent layer 9 of the clear paint is formed so as to cover the reference surface Sa and fill the inside of the small circular recess 6.

Even if the light reflecting surface S is covered with the transparent layer 9, the flat reference surface Sa on which the metal is exposed and the hemispherical bottom surface of the small circular recess 6 become the light reflecting surface S capable of reflecting light, and the light is transmitted by the reference surface Sa. In addition to simple flat surface reflection, spherical reflection scattered in multiple directions can be performed by the small circular recess 6.
