摘　　要：Nowadays,in order to expand the roof view to bring passengers closer to nature,more and more new energy vehicles are opting for canopy designs without sunshades.However,after removing traditional sunshades,new solutions must be sought to address issues such as heat insulation,glaring sunlight,and interior reflections from the roof glass during the summer months.This paper conducts an in-depth analysis of the technical advantages and shortcomings of sunshade-free canopy in terms of heat insulation and interior reflections during summer,from both theoretical analysis and experimental comparison perspectives,and proposes improvement strategies.The research results indicate that although the panoramic roof enhances the vehicle's interior view and technological appeal,it still has shortcomings in terms of heat insulation and the problem of interior reflections caused by direct sunlight.The proposed improvement strategies can effectively mitigate these issues,and offers consumers more comfortable and intelligent driving experiences.目前,为了拓宽车顶视野,让乘客更贴近自然,越来越多的新能源车型选择采用无遮阳帘的全景天幕方案。这种设计去除了传统遮阳帘,并寻求新的解决方案来应对天幕玻璃在夏季的隔热、刺眼阳光以及车内倒影等问题。从理论分析和试验对比,深入研究了无遮阳帘天幕在夏季隔热和车内倒影方面的技术优势和缺陷,并提出改善策略。研究结果表明,虽然全景天幕提升了车内的视野和科技感,但在隔热和阳光直射引发的车内倒影问题上仍存在缺陷,提出的改善策略可有效缓解这些问题,为消费者带来更舒适、智能的驾乘体验。
