Embodiment 1

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

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

[0039] The variable magnification lens assembly 2 includes a variable magnification lens 21 for enlarging or reducing the image projected by the display screen assembly 1 and reversing the optical path, and a variable magnif...

Embodiment 2

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

[0110] In this example, since only the vehicle-mounted head-up display system on the car is improved, and other parts on the car are not improved, and the vehicle-mounted head-up display system has been specifically explained in the above-mentioned embodiment 1, it is no longer repeat.

[0111] The automobile provided by the present invention is equipped with the vehicle-mounted head-up display system disclosed in the present invention, which can adjust the focal length of the optical path of the entire vehicle-mounted head-up display system to realize continuous zooming, and its conjugate distance remains unchanged. For the entire system, the object Both the distance and the image distance remain unchanged, only the magnification of the system is changed, and the text information and other content in the projected image are enlarged....

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...
