Problems solved by technology

[0004] The current HUD can be divided into two types: built-in type and external type according to the installation position, but no matter whether it is a built-in type or an external type, there are some places that cannot meet people's needs.
[0005] In the existing structure of the head-up display, the projection distance of the HUD is often fixed and short, and the driver cannot adjust the projection distance, so he cannot freely choose the most comfortable projection distance according to his actual situation. Poor degree, not humanized enough

Abstract

The invention relates to a head-up display, which comprises at least one reflector and at least one adjustable reflector group, wherein the adjustable reflector group is set to have at least one projection state and at least one non-projection state. When the adjustable reflector group is in the projection state, the adjustable reflector group is matched with the reflector to reflect imaging light, reflects the imaging light to a light receiving surface and enables the imaging light to be reflected by the light receiving surface so as to enable a user to sense the imaging light reflected by the light receiving surface and a virtual image formed by the imaging light through the light receiving surface; and when the adjustable reflector group is in the non-projection state, the imaging lightis directly reflected by the reflector to form the virtual image, so that at least two selectable projection effects are formed.

Description

technical field [0001] The present invention relates to a vehicle-mounted device of a motor vehicle, and further relates to a Head-Up Display (HUD) with an adjustable projection distance. Background technique [0002] With the continuous development of the automobile industry, the number of automobiles and the performance of automobiles have been continuously improved. As for the most common means of travel for people, safety is an extremely important aspect that needs to be paid attention to in its development. [0003] As we all know, all kinds of traffic, such as cars and airplanes, are composed of various parts, and the information displayed on various dashboards, such as vehicle speed, engine RPM, temperature and fuel level, etc., can help drivers drive better. However, in the process of driving, people often need to pay attention to several places at the same time, such as the instrument panel, GPS, mobile phone, road conditions ahead, rearview mirror and so on. The ...
