Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to multi-color automotive spoilers. Background Technology

[0002] A car spoiler is a component mounted on the rear hatch of a car, resembling an inverted aircraft tail fin; it's also commonly referred to as a "car rear wing." Some cars are equipped with front spoilers, often called air dams. On one hand, spoilers add a dynamic look to a car; on the other hand, their more important function is to effectively reduce air resistance at high speeds, thereby improving vehicle stability and fuel economy. Currently, most spoilers are blow-molded, then sanded and painted. Because blow-molded spoilers are one-piece designs, their colors are limited, lacking the diverse styles of modern car exterior designs. Utility Model Content

The body has an upper body snap-fit ​​structure on one side and a lower body snap-fit ​​structure on the other side. The upper outer panel has an upper snap-fit ​​structure on its inner side corresponding to the upper body snap-fit ​​structure of the body. The lower outer panel has a lower snap-fit ​​structure on its inner side corresponding to the lower body snap-fit ​​structure of the body. The upper outer panel, lower outer panel, and body are all different colors. Both the upper and lower outer panels are fixedly connected to the body using double snap-fit ​​and adhesive bonding. The upper outer panel is positioned and snap-fitted to the upper body snap-fit ​​structure on one side of the body via its inner upper snap-fit ​​structure, and is also fixedly connected to one side of the body via adhesive. The lower outer panel is positioned and snap-fitted to the lower body snap-fit ​​structure on the other side of the body via its inner lower snap-fit ​​structure, and is also fixedly connected to the other side of the body via adhesive.

[0006] The adhesive used to fix the inner side of the upper outer panel to one side of the main body is located in the middle of the inner side of the upper outer panel and near the outer contour, forming a discontinuous adhesive strip with a width of 8mm-12mm and a thickness of 0.8mm-1mm. The adhesive used to fix the inner side of the lower outer panel to the other side of the main body is located in the middle of the inner side of the lower outer panel and near the outer contour, forming a discontinuous adhesive strip with a width of 8mm-12mm and a thickness of 0.8mm-1mm.
