The invention provides a vehicle-mounted rear-row projection display system. The system comprises a vehicle-mounted display system screen which is used for displaying an image, is embedded into the front end of a vehicle-mounted navigation bridge, and is parallel to a vehicle roof, a reflection system which is used for transmitting the image light emitted by the screen of the vehicle-mounted system into the projection lens through reflection, the projection lens which is used for receiving the image light emitted by the reflection system and projecting the image light to a display screen, thedisplay screen which is used for reflecting the image light image projected by the projection lens, and an adjusting mechanism which is used for correspondingly adjusting the reflection system and theprojection lens according to the position of the image light image projected by the projection lens on the display screen, so that the image is displayed to passengers in the back row at the proper position of the display screen. Passengers in the back row can conveniently watch images in a comfortable posture. And fatigue caused by long-term watching of images in a fixed posture by passengers inthe back row is reduced.

    本发明提供了一种车载后排投影显示系统,包括:车载显示系统屏幕,用于显示图像,所述车载显示系统屏幕嵌入车载驾驶台前端,且与所述车顶平行;反射系统,所述反射系统用于将车载系统的屏幕发出的图像光线经过反射传入投影镜头;投影镜头,所述投影镜头用于接收反射系统发射的图像光线并投射到显示屏幕上;显示屏幕,所述显示屏幕用于反射投影镜头投射的图像光线图像;调整机构,所述调整机构用于根据所述投影镜头投射的图像光线图像在显示屏幕的位置对反射系统和投影镜头进行对应调整,以使得所述图像在显示屏幕的合适位置向后排乘客展示图像。便于后排乘客以较为舒适的姿态观看图像。减少了后排乘客长期以固定姿态观看图像造成的疲劳。
