Description

Technical Field

[0001] The utility model relates to a sunshade curtain structure, in particular to a car sunshade curtain structure, belonging to the technical field of car parts. Background Art

[0002] At present, most of the car sunshades on the market are motor-driven zippers, which then drive the sunshades to open or close. In this structure, since the zipper itself is soft, a specific track is usually required to limit the movement path of the zipper, and the outer side of the zipper is usually set as a spiral structure to facilitate the use of a motor with a turbine structure to drive it. When the zipper slides in the track, due to the rough structure of the outer side of the zipper, the zipper will generate a large friction with the track, and the sliding will produce noise. Especially after long-term use, when the internal grease fails, the noise will be higher, and the resistance will also greatly increase, causing the zipper to wear. Utility Model Content
