The invention relates to the technical field of head-up display, in particular to a reflecting mirror transmission system of a head-up display and the head-up display, and aims to improve the reliability of the head-up display. The reflecting mirror transmission system of the head-up display comprises a rotary reflecting mirror, a detection rod and a detection device, wherein the rotary reflecting mirror is provided with a reflecting surface and a back part deviating from the reflecting surface; the detection rod comprises a contact at one end; the detection device is adjacent to the detection rod; wherein the contact is attached to the back, so that the rotary reflecting mirror pushes the detection rod to move during rotation, the detection device is used for acquiring displacement information of the detection rod and sending the displacement information to a control module of the head-up display, and the control module is used for acquiring the displacement amount of the detection rod according to the displacement information. According to the reflecting mirror transmission system and the head-up display, the actual operation position of the rotating reflecting mirror can be obtained, so that the display function fault of the head-up display caused by the fact that the rotating reflecting mirror does not operate in place is monitored.
本公开涉及抬头显示技术领域,具体而言,涉及一种抬头显示器的反射镜传动系统与抬头显示器,目的在于提高抬头显示器的可靠性。抬头显示器的反射镜传动系统包括旋转反射镜、检测杆与检测装置,旋转反射镜具有反射面与背离反射面的背部;检测杆包括一端的触头;检测装置与检测杆相邻设置;其中,触头与背部相贴设置,以使旋转反射镜在旋转时推动检测杆移动,检测装置用于获取检测杆的位移信息,并发送至抬头显示器的控制模块,控制模块用于根据位移信息获取检测杆的位移量。本公开的反射镜传动系统与抬头显示器,能够获取旋转反射镜的实际运转位置,从而监测由于旋转反射镜运转不到位而引起的抬头显示器显示功能故障。
