Technical Field
The invention relates to a skylight sunshade curtain cloth, in particular to a curtain cloth of an automobile skylight sunshade curtain.
Background
The sun-shading curtain for the automobile skylight mainly comprises curtain cloth, a scroll and a cross beam, wherein the front end of the curtain cloth is fixed on the cross beam, and the rear section of the curtain cloth is wound on the scroll. The opening and closing of the curtain is achieved by fitting the sun blind to the skylight frame. The front cross beam is assembled in the rails on two sides of the frame through the sliding feet at two ends, and the tail scroll is assembled on the frame through the fixing mechanisms at two ends. The motor drives the sliding foot to run in the track and drives the cross beam to move back and forth, so that the curtain cloth is opened and closed. The curtain cloth keeps a certain longitudinal tension by means of a force storage device in the reel, and passively uncoils and coils when the cross beam moves forwards and backwards.
The curtain cloth generates longitudinal and transverse tension due to the large tension accumulated on the reel, particularly the maximum tension when the curtain cloth is completely closed, the curtain cloth can generate longitudinal stripes under the action of the longitudinal tension, and the curtain cloth inwards extrudes the skylight frame under the action of the transverse force.
