The invention relates to the technical field of vehicle-mounted head-up displays, in particular to an auxiliary polarizer for a vehicle-mounted head-up display, and the auxiliary polarizer comprises a base which is used for being arranged in a sight line path which is a light propagation path between a driver and a projection picture; the polarized lens is a circular lens; the adjusting mechanism comprises a loading part connected with the base, and the polarized lens is rotationally connected with the loading part; the plurality of extrusion rollers are arranged on the side wall of the loading part; and the extrusion roller clamps the polarized lens, so that the polarized lens is in a vertical posture, and the polarized lens is rotationally connected with the loading component. By using the auxiliary polarizer, a driver can still see a projection picture of a head-up display clearly while wearing polarized sunglasses in any polarization direction to filter reflected light and glare.

    本发明涉及车载抬头显示器技术领域,尤其是一种用于车载抬头显示器的辅助偏振镜,包括,底座,用于设置于视线路径中,所述视线路径为,驾驶员与投影画面的光线传播路径;偏振镜片,所述偏振镜片为圆形透镜;调节机构,所述调节机构包括:与所述底座连接的装载部件,所述偏振镜片与所述装载部件转动连接;以及设置于所述装载部件侧壁的多个挤压辊;所述挤压辊夹持所述偏振镜片,以使所述偏振镜片处于竖直位姿,且使所述偏振镜片与所述装载部件转动连接。使用本申请的辅助偏振镜,司机能够在佩戴任意偏振方向的偏振墨镜过滤反光和眩光的同时,依然能够看清抬头显示器的投影画面。
