Multi-view area head-up display device and its multi-sandwich imaging mirror

Abstract

The invention discloses multi-visual area head-up display equipment and a multi-sandwich imaging mirror thereof. The multi-visual area head-up display equipment comprises a projector generating a projection image to a reflector to reflect a reflection image to the multi-sandwich imaging mirror, the reflection image comprises at least two overlapped images which are mutually overlapped, a half-reflection surface of the overlapped image is relatively inclined to a half-reflection surface of the adjacent overlapped image, when the reflection image is projected to a half-reflection surface of theupper-most overlapped image, a virtual image can be reflected, the reflection image better penetrates through the upper-most overlapped image to the lower-layer overlapped image, so another virtual image is reflected by a half-reflection surface of the lower-layer overlapped image, and at least two virtual images at different visual areas are presented. The multi-visual area head-up display equipment is advantaged in that a driver is facilitated to view the vehicle body information projected by the multi-visual area head-up display equipment in multiple angles and heights, and driving convenience and safety of the driver are effectively improved.

Description

technical field [0001] The invention relates to a head-up display device, in particular to a multi-view zone head-up display device and a multi-interlayer imaging mirror thereof. Background technique [0002] The Head Up Display (HUD) was originally a flight aid instrument commonly used in aviation tools. As the name suggests, the Head Up Display means that the pilot can look up, and can directly see the important information needed on the Head Up Display without looking down. information. At present, many automobile manufacturers have spotted the convenience and safety advantages of the head-up display device, and have begun to install the head-up display device on the car to assist the driver in driving and improve the driving safety of the driver. [0003] With the continuous improvement and development of vehicle head-up displays, the current vehicle head-up display devices can display not only vehicle speed, tire pressure, navigation and other screens, but also have th...

Problems solved by technology

Therefore, due to the narrow projection range of the current existing head-up display device, it is easy to limit the degree of freedom of the driver's posture, so that the driver's movable posture is subject to many restrictions, which is quite inconvenient for the driver.
