Description

Technical Field

[0001] This utility model belongs to the field of vehicle head-up display (HUD) technology, specifically relating to a PGU mounting structure for a head-up display. Background Technology

[0002] In the technological development of automotive head-up display (HUD) systems, the mounting structure and accuracy of the image generation unit (PGU) are key factors affecting the overall performance and reliability of the HUD. Traditional HUD architectures have revealed numerous problems with PGU installation. Traditional mounting structures are prone to installation accuracy errors. For example, traditional structures often result in significant horizontal installation errors, leading to left-right shifts in the projected image within the driver's field of vision. This shift is exacerbated by changes in vehicle driving posture or thermal expansion and contraction of components due to temperature variations. Furthermore, traditional mounting structures can cause vertical instability in the PGU, resulting in projected images that are positioned too high or too low, failing to meet user needs. For example, traditional installation structures can easily lead to installation errors in the angular accuracy of the PGU. These errors can cause deviations in the pitch and yaw angles of the PGU. Pitch angle deviations can make the projected image position inaccurate, affecting the driver's visual focus and reading efficiency. Yaw angle deviations can cause deviations in the correspondence between navigation and other directional information and the actual driving direction in the driver's field of vision when the vehicle is turning or changing lanes. This can lead to the driver misunderstanding the driving path and easily cause incorrect driving operations.
