The invention discloses a sunshade curtain rolling mechanism and an automobile skylight, and relates to the related technical field of automobile skylights. The rolling mechanism comprises two supports, a fixing shaft, an elastic piece arranged on the fixing shaft in a sleeving mode and an outer rotating shaft; the two supports are parallel to each other and are spaced by a preset distance. The two ends of the fixing shaft are connected to the two supports respectively; the elastic piece is fixed on the fixed shaft, and the two ends of the elastic piece are symmetrically arranged relative to the fixed position of the elastic piece and the fixed shaft and can rotate around the axis of the fixed shaft; the outer rotating shaft is arranged outside the elastic piece in a sleeving manner and isconfigured to drive the two ends of the elastic piece to rotate; and the sunshade curtain is rolled on the outer rotating shaft. The outer rotating shaft rotates by a preset angle when the sunshade curtain is unfolded, the two ends of the elastic piece rotate along with the outer rotating shaft, and deformation generated by the two ends of the elastic piece relative to the fixed position of the elastic piece forms rewinding torsion of the outer rotating shaft. The two ends of the outer rotating shaft wind the sunshade curtain with the same rewinding torque, the stability of the rolling mechanism is improved, and the problems that the sunshade curtain is stacked, wrinkled and even stuck are solved.
本申请公开了一种遮阳帘卷收机构及汽车天窗,涉及汽车天窗相关技术领域,卷收机构包括两个支座、固定轴、套设于固定轴的弹性件和外转轴;两个支座相对平行且间隔预定距离;固定轴的两端分别连在两个支座上;弹性件固定在固定轴上,弹性件的两端相对于弹性件与固定轴的固定位置对称布置,且可绕固定轴的轴心旋转;外转轴套设在弹性件的外部,并被配置为可带动弹性件的两端转动;遮阳帘卷设于外转轴上。外转轴在遮阳帘展开时旋转预定角度,弹性件的两端随外转轴转动,弹性件的两端相对于弹性件的固定位置产生的形变构成外转轴的回卷扭力;外转轴的两端以相同的回卷扭矩卷收遮阳帘提高了卷收机构的平稳性,改善遮阳帘堆积、褶皱、甚至卡死的问题。
