Problems solved by technology

[0003] In vehicle-mounted applications, considering the impact of differences in sitting posture on HUD display, the existing technology generally increases the field of view of HUD so that the driver can observe in different postures; the disadvantage is that a larger projection screen is required , resulting in blocking the driver's line of sight and affecting driving safety
If a small projection screen is used, it needs a large adjustment range due to its narrow field of view; limited by its own structure, the existing HUD adjustment range is very limited, which is difficult to meet the application needs

Abstract

The invention discloses an HUD with a free adjustment function. The HUD comprises a bearing seat, a projection device and a semi-reflective semi-transmissive screen, wherein the bearing seat is provided with a bearing guiding plane; the projection device is arranged on the bearing seat and used for projecting image information; the semi-reflective semi-transmissive screen is used for displaying the image information projected by the projection device and is provided with a movable end which is magnetically attracted to the bearing guiding plane, and the semi-reflective semi-transmissive screencan slide along the bearing guiding plane and rotate around the normal of the bearing guiding plane through the movable end. Through the HUD with the free adjustment function, free adjustment of theposition of the semi-reflective semi-transmissive screen can be realized, it is not needed to increase the size of the semi-reflective semi-transmissive screen, and the HUD meets observation requirements of different drivers.

Description

technical field [0001] The invention belongs to the technical field of heads-up displays, in particular, it is a freely adjustable HUD. Background technique [0002] Head Up Display (Head Up Display), referred to as HUD. Head-up displays first appeared on military aircraft to reduce the frequency with which pilots had to look down at instruments to avoid distraction and loss of situational awareness. HUD can effectively improve driving convenience and safety, and it is also widely used in civil aviation airliners, and is gradually introduced into the automotive field. [0003] In vehicle-mounted applications, considering the impact of differences in sitting posture on HUD display, the existing technology generally increases the field of view of HUD so that the driver can observe in different postures; the disadvantage is that a larger projection screen is required , resulting in blocking the driver's line of sight, affecting driving safety. If a small projection screen is...
