Sunshade roller blind device for car sunroof

Abstract

Provided is a roller blind device for an automobile sunroof, comprising a roller blind cloth (1), a winding guide assembly (2) and a guide rail (3). The winding guide assembly (2) comprises a guide passageway (202) having a deformation part (203). The deformation part (203) can guide and deform a reinforcing band (101) on two sides of the roller blind cloth (1) before it enters a matching rail, and can flip the reinforcing band (101) or separate it from the bottom roller blind cloth (1), thus preventing a situation whereby sliding in the guide rail is not smooth and the strength of the cloth in the fringe area of the roller blind cloth is not enough, leading to pulling not being smooth and even deformation and tearing after long-term use.

Description

technical field [0001] The invention relates to a roller blind device for an automobile, in particular to a sunshade roller blind device for an automobile sunroof, and belongs to the field of automobile spare parts. Background technique [0002] Sunshade roller blinds are installed on the sunroof of the car. When the sunroof does not need to be opened or the sun is directly exposed to the sun, the sunshade roller blind can be unfolded to prevent the sun from exposing the car to the sun; Roll up the roller sunblind to reveal the sunroof. The sunshade roller blind usually includes a roller blind and a winding device. One end of the roller blind is wound on the winding device, and the other end of the roller blind is driven by a pulling device through a motor or manually pulled, and the roller blind is pulled out or rewind. [0003] At present, when the existing winding device is applied to the rolling blind fabric, although there are also reinforcement belts on both sides of...

AI Technical Summary

Problems solved by technology

[0003] At present, when the existing winding device is applied to the rolling blind fabric, although there are also reinforcement belts on both sides of the rolling blind fabric, the reinforcing belt is directly wound on the winding device and pulled out along the main extension direction. In this way, in the process of winding and stretching, since the guide strips on the reinforcing strips on both sides of the roll curtain fabric are generally very thin and flat metal shrapnel with memory function, direct contact with the guide rail or the winding device will cause extension and retraction. The roll is not smooth, and at the same time, because the roll screen is pulled straight in and out during the extension process, the strength of the fabric in the edge area of ​​the roll screen is not enough. After long-term use, the pull will not be smooth or even deformed and torn.
