The invention discloses an anti-abrasion track of an automobile skylight, and belongs to the field of automobile skylight tracks, the anti-abrasion track comprises a track body, and a sliding block is installed in an inner cavity of the track body in a sliding mode; the device further comprises a crossing assembly, the crossing assembly comprises movable cavities evenly formed in the bottom of the sliding block, fixing frames are installed in inner cavities of all the movable cavities in a sealed and sliding mode, rolling shafts are rotatably installed on the two side walls of inner cavities of all the fixing frames, and rolling wheels are fixedly installed between every two adjacent rolling shafts. Each group of rollers are in contact with the bottom wall of the inner cavity of the track body; according to the skylight opening and closing device, original sliding friction can be changed into rolling friction, friction force can be remarkably reduced, the service life of the skylight opening and closing device can be prolonged, meanwhile, the roller can automatically move upwards to cross foreign matter, the situation that friction is generated between an original sliding block and the foreign matter, and the sliding block is clamped and damaged is avoided, and the opening and closing smoothness of a skylight can be effectively improved.
本发明公开了一种汽车天窗的防磨损式轨道,属于汽车天窗轨道领域,包括轨道本体,所述轨道本体的内腔滑动安装有滑块;还包括:越过组件,所述越过组件包括均匀开设在所述滑块底部的活动腔,各组所述活动腔的内腔均密封滑动安装有固定框,各组所述固定框的内腔两侧壁上均转动安装有滚轴,相邻两组所述滚轴之间固定安装有滚轮,各组所述滚轮均与所述轨道本体的内腔底壁接触设置;可以实现将以往的滑动摩擦改成滚动摩擦,可以显著减少摩擦力和提高其使用寿命,同时通过滚轮能够自行向上移动越过异物,避免了以往滑块与异物产生摩擦,还会导致其卡住损坏的情况,可有效的提高天窗开关的流畅性。
