Description

TECHNICAL FIELD

[0001] The utility model relates to a head-up display, in particular to a light reflection structure of head-up display. BACKGROUND

[0002] The light reflection structure of head-up display is mainly used for receiving the light of HUD module, and then reflecting the light into the eyes of the driver to realize the function of head-up display. The Japanese patent with the application date of June 15, 2007, the announcement number of JP2008308090A and the name of "vehicle head-up display" discloses a head-up display for a vehicle capable of obtaining display visibility with extremely high contrast, which mainly installs the HUD module at the bottom of the black printed area of the windshield, and the light emitted by the HUD module is reflected into the eyes of the driver after being irradiated to the black printed area of the windshield, thereby realizing the function of head-up display. However, as shown in the figure, the black area of the front windshield of the vehicle is limited by regulations. The standard of "GB11562-2014 requirements and measurement methods for the front field of view of the driver of the vehicle" regulates the field of view line V2 (commonly known as regulation line 6 in the industry) of the front field of view of the driver of the vehicle. The field of view line V2 is formed by the line of sight of the driver from the eye position, the front inclination, the tangency to the upper edge of the steering wheel and the extension to the front of the windshield. In order not to hinder the field of view of the driver, any line of sight obstruction must be located below the regulation line. Therefore, the top of the black area of the windshield also needs to be located below the regulation line. Figure 1

[0003] In order to enable the light emitted by the HUD module to be irradiated to the black printed area of the windshield of the vehicle, the HUD module needs to be installed close to the bottom of the black area of the windshield close to the engine compartment. However, this installation position is easily disturbed by the internal layout of the vehicle body such as the wiper motor and the steering wheel support, thereby causing certain difficulties in the installation of the HUD module.
