The invention discloses a vehicle-mounted head-up display device and a vehicle, and the device is characterized in that a first waveguide comprises a first surface and a second surface which are oppositely arranged, and the first surface and/or the second surface are/is provided with a diffraction coupling-in structure and/or a diffraction coupling-out structure; the second waveguide comprises a third surface and a fourth surface which are oppositely arranged, a diffractive optical structure is arranged on the third surface and/or the fourth surface, and the diffractive optical structure and the diffractive coupling-out structure are correspondingly arranged; the first waveguide and the second waveguide are arranged oppositely, the second surface and the third surface are arranged adjacently, the diffraction coupling-in structure is used for coupling an image light beam emitted by an optical machine into the first waveguide, the diffraction coupling-out structure is used for coupling out the image light beam to the diffraction optical structure of the second waveguide, and the diffraction optical structure is used for coupling in the image light beam to the second waveguide. And the image light beam is coupled to a vehicle-mounted windshield and then is reflected to the visual field of a driver. According to the vehicle-mounted head-up display device provided by the invention, the space is saved, and a larger exit pupil can be realized.

    本发明公开了一种车载平视显示装置和车辆,装置包括:第一波导包括相对设置的第一表面和第二表面,第一表面和/或第二表面上设置有衍射耦入结构和/或衍射耦出结构;第二波导包括相对设置的第三表面和第四表面,第三表面和/或第四表面上设置有衍射光学结构,衍射光学结构与衍射耦出结构对应设置;第一波导与第二波导相对设置,第二表面与第三表面近邻设置,衍射耦入结构用于将光机出射的图像光束耦入至第一波导,衍射耦出结构用于耦出图像光束至第二波导的衍射光学结构,衍射光学结构用于耦入图像光束至第二波导,还耦出图像光束至车载挡风玻璃后反射至驾驶员视野。本发明提供的车载平视显示装置节省空间,还能实现较大的出瞳。
