Example Embodiment

[0036] Example 1

[0037] In this example, the vehicle head-up display system provided by the present invention will be specifically explained, such as figure 1 As shown, it includes a display screen assembly 1 and a three-reflection optical assembly, which is located on the exit light path of the display screen assembly 1, and reflects the image projected by the display screen assembly 1 to the front windshield of the car 5 on; the car front windshield 5 reflects the image to the human eye;

[0038] Wherein, the three-reverse optical assembly includes a variable magnification lens assembly 2, an image quality compensation lens assembly 3, and a front stop compensation lens assembly 4 sequentially arranged on the optical path;

[0039] The variable power lens assembly 2 includes a variable power lens 21 for zooming in or out of the image projected by the display screen assembly 1 and folding the optical path, and a variable power lens 21 for adjusting the focal length of the variable...

Example Embodiment

[0108] Example 2

[0109] This example provides an automobile, including the on-vehicle head-up display system specifically explained in the above embodiments.

[0110] In this example, since only the on-board head-up display system on the car is improved, other parts of the car are not improved, and the on-board head-up display system has been specifically explained in the above embodiment 1, so it will not be Go into details.

[0111] The car provided by the present invention, on which the vehicle head-up display system disclosed by the present invention is installed, can adjust the focal length of the optical path of the entire vehicle head-up display system to achieve continuous zooming, and its conjugate distance remains unchanged. For the entire system, Both the distance and the image distance are unchanged, only the magnification of the system is changed, and the text information in the projected image is enlarged. The system can magnify the content of the projected image se...

Abstract

In order to solve the problems of the prior art such as the small sizes of the images projected by the conventional on-board head-up display systems and the limited information displayed by the projected images, the invention provides an on-board head-up display system comprising a display screen assembly and a three-reflection type optical assembly. The three-reflection type optical assembly comprises a zoom lens assembly, an image quality compensation lens assembly, and a front windshield compensation lens assembly, which are sequentially arranged on an optical path. The zoom lens assembly comprises a zoom lens body and a zoom lens focusing assembly. The image quality compensation assembly comprises an image compensation lens body and an image compensation lens focusing assembly. The on-board head-up display system is advantageous in that the continuous zooming can be realized, and the projected image can be magnified by a plurality of times even dozens of times, and the position of the image surface can be remained; the image surface quality is stable, and the image surface cannot be fuzzy or deformed because of the magnification; the abundant information can be provided for the driver in the limited space, and the technical guarantee can be provided for the enriching of the use functions of the on-board head-up display system.

Description

technical field [0001] The invention relates to the field of vehicle-mounted head-up display systems. Background technique [0002] With the improvement of people's living standards, the requirements for cars are higher. Some existing cars have been installed with head-up display systems (English abbreviation: HUD, English full name: HeadsUpDisplay), also known as head-up displays. On the platform, the vehicle head-up display system uses the principle of optical reflection to project information on the front windshield in the form of text and graphics. The height of the projected image is roughly at the same level as the driver's eyes. The driver can watch the virtual image formed by the image projected by the vehicle-mounted head-up display system after being reflected by the front windshield in front. In this way, the driver can easily integrate the external scene with the information displayed on the head-up display during driving, which is very comfortable to watch. The...
