Adjustable head-up display device

摘要

The invention relates to a head-up display device, including a projector for generating a light beam carrying information to be displayed, a combiner having a display position for displaying the information in the field of vision of a user, and an optical system defining an optical path between the projector and the combiner when the latter is in the display position thereof, for directing the light beam onto the combiner. The optical system includes a first and a second deflecting mirror. The first mirror is arranged for receiving the light beam from the projector and for sending said light beam to the second mirror, the latter being arranged for sending the light beam over the optical path toward the combiner. An actuation system is provided for adjusting the length of the optical path between the projector and the combiner by positioning the first and second deflecting mirrors.

主权项

1. A head-up display device, comprising:
a projector to generate a light beam conveying information to be displayed; a combiner having a display position to display the information in the field of view of a user; an optical system defining an optical path between the projector and the combiner when the combiner is in the display position, said optical system configured to direct the light beam at the combiner, wherein the optical system comprises at least a first deviation mirror and a second deviation mirror in the optical path, the first deviation mirror being arranged to receive the light beam from the projector and return it towards the second deviation mirror, the second deviation mirror being arranged to return the light beam on the optical path towards the combiner; and an actuation system configured to adjust the length of the optical path between the projector and the combiner by positioning of the first and second deviation mirrors the one relative to the other, wherein the actuation system comprises a mechanism coupled to the first deviation mirror and the second deviation mirror, and driven by a motor.
