Abstract
The invention relates to a driving assisting head-up device. The driving assisting head-up device mainly comprises a light source (1), a collecting mirror (3), a reflecting mirror (4), a lens (5), a lens assembly (6) and a projective display screen (7), wherein light emitted by the light source (1) is reflected to the lens (5) by the reflecting mirror (4) after passing through the collecting mirror (3), then reaches the projective display screen (7) via the lens assembly (6) after penetrating the lens (5), and is finally displayed by the projective display screen (7) to be projected into human eyes (8); the normal directions of both the lens assembly (6) and the projective display screen (7) form an angle of 45 degrees. According to the invention, owing to combined use of the lens, the lens assembly and the collecting mirror, the imaging quality is improved to provide clear display images for a driver, so that definite impurity-free navigation images can be provided for the driver driving at night.
