Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0031] In addition, in t...

Abstract

The invention discloses a head-up display device, a head-up display instrument and a vehicle. The head-up display device comprises a light source, a polarization conversion piece and a first polaroid,and the light source emits first polarized light. The polarization converter has a first position away from the light source and a second position close to the light source. The first polaroid is arranged in a light path of light emitted by the light source. The polarization conversion piece is located at the first position, the first polarized light does not pass through the polarization converter, the polarization state of the first polarized light is not changed, and the first polarized light is emitted to the first polarizer to be reflected. When the polarization converter is located at the second position, the first polarized light passes through the polarization converter, the polarization state of the first polarized light is changed, the first polarized light emits second polarized light through the polarization converter, and the second polarized light is emitted to the first polaroid to be transmitted. According to the technical scheme, the projection module can be effectively prevented from integrally moving, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of vehicle displays, in particular to a head-up display device, a head-up display instrument and a vehicle. Background technique [0002] Head Up Display (HUD, Head Up Display) system, also known as parallel display system, the function of the head up display system is to project important driving information such as speed and navigation onto the windshield in front of the driver or other display devices. Let the driver try to see important driving information such as speed and navigation without bowing or turning his head. [0003] With the rapid development of intelligent driving technology, the head-up display technology of augmented reality is becoming more and more important. Therefore, it is necessary to adjust the size of the virtual image in the head-up display system, that is, the distance between the virtual image and the display device needs to be adjusted. The method of distance is to move the p...
