Problems solved by technology

However, this method of installation and adjustment has large errors, and at the same time, it has higher requirements on the equipment itself during the installation process.
The split-type head-up display installed according to the above method has a large angle error of the display module and is not suitable for quick installation
At the same time, the brightness of the image displayed in the split-type head-up display is reduced and there is a large deformation
In addition, the error of the split head-up display exceeds the design requirements, which may affect driving safety.

Embodiment 1

[0069] In this example, the center of the theoretically designed virtual image is located on the driver’s horizontal line of sight, and the imaging distance of the virtual image center from the driver’s viewing point is 2 meters. The corresponding viewing angle of the virtual image is α×β=6°×3° (horizontal×vertical). straight). α is the horizontal angle of view, the width of the virtual image in the horizontal direction, corresponding to the opening angle of the human eye, and represents the size of the virtual image in the horizontal direction. β is the vertical angle of view, the height of the virtual image in the vertical direction, corresponding to the opening angle of the human eye, and represents the size of the virtual image in the vertical direction. The virtual image has no rotation or tilt, that is, the virtual image plane is perpendicular to the driver's horizontal line of sight, the length direction of the virtual image is parallel to the horizontal plane, and the w...

Abstract

The invention provides an installation and adjustment method, and an installed and adjusted split type head-up display. The installation and adjustment method comprises the steps of: pre-installing animaging optical module and a display module to obtain a first pre-installation position and a second pre-installation position, adjusting a position and an angle of the display module according to the first pre-installation position to obtain a third pre-installation position, adjusting an angle of the display module according to an auxiliary light source image and the third pre-installation position to obtain a fourth pre-installation position, readjusting an angle of the display module according to the fourth pre-installation position, and completing the installation and adjustment. According to the split type head-up display obtained by adopting the installation and adjustment method, the installation precision of the display module is increased, the effect can be watched with eyes directly, and thus the rapid installation of the split type head-up display is realized.

Description

Technical field [0001] The invention relates to the field of automobile head-up displays, in particular to an assembly method and an assembled split head-up display. Background technique [0002] In order to facilitate the driver to view vehicle information, navigation information, etc., the image projected by the head-up display is reflected by the windshield into the eye box area for the driver to view. [0003] The split-type head-up display is generally deployed in the following way: the imaging optical module is installed on the car dashboard or embedded in the car dashboard, and the display module display is located above the car windshield. The imaging optical module and the display module are independent of each other, and there is no fixed connection mechanism. Therefore, when assembling to the car, a certain assembly and adjustment method is required. During the installation process, the angle accuracy of the display module is required to be high. When the angle of the ...
