Description

Cover plate assembly for vehicle outer body part

Field of Invention

The present invention relates to a cover plate assembly for a vehicle outer body part.

Background

As for typical automobile models, a cover plate, as a separate single part, is usually assembled on a vehicle outer body part in a joint part for example between a bumper skin and a lower trim, or between a running board and a lateral and lower part adjacent to a wheel of a body part, or in a headlight washer area. Such a one-piece cover plate is usually monochromatic.

However, in view of the fashion and style of the entire body part, the cover plate shall be processed by two surface treatment manners to satisfy different requirements for appearance quality and matching. For instance, in case of a tow hook cover plate, the tow hook cover plate is juxtaposed both to a bumper skin and to a lower trim. A part of the tow hook cover plate, serving as a part of the bumper skin, needs to be textured as the bumper skin, whereas the other part of the tow hook cover plate, serving as a part of the colored and injection-molded lower trim, needs to be spray-painted. Since the two parts are integrally formed, if one part is spray-painted, the other part shall be shielded. However, the defect rate of such shielded spraying is relatively high, and there are always obvious chromatic aberration between the sprayed part and the colored and injection-molded lower trim, such that customers’ requirements for colour matching cannot be met and the painting cost will accrue accordingly.
