Description

Technical Field

[0001] The utility model relates to the technical field of upper decorative plate assemblies, in particular to an upper decorative plate assembly structure of a central channel. Background Art

[0002] The upper trim assembly structure is a part of the upper trim assembly of the central channel of the car, and it serves as a decoration and cup holder. The upper trim is a high-gloss spray-painted part, and has very strict requirements on the surface of the injection molded part, especially the problem of surface shrinkage. The conventional base wall thickness and the rib thickness ratio of the back rib is about 3:1, which can weaken and improve the surface shrinkage. The existing product has a cross-shaped rib structure, and the rib thickness at the intersection is greater than 1mm, which will produce obvious shrinkage on the surface of the high-gloss part, narrowing the injection molding process window. The obvious shrinkage will cause customer complaints and reduce the product rationality rate. The cup holder and the upper trim body are large products, and the matching circumference requirements are high. The current product structure has insufficient limit support, which will cause slight deformation of the product. The gap surface difference is uneven after matching, affecting product quality.

[0003] In general, the surface reduction quality of existing product structures cannot be guaranteed, there are few circumferential limits, and the product matching gap cannot be guaranteed. Utility Model Content
