Description

TECHNICAL FIELD

[0001] The utility model belongs to stray light analysis technical field relates to a kind of stray light analysis devices of automobile HUD light shield. BACKGROUND

[0002] In the automotive industry, the application of Head-Up Display (HUD) technology has become an important part of vehicle intelligence and safety. The HUD system displays vehicle information, such as speed, navigation information and warning prompts, on a transparent screen within the driver's field of view, allowing the driver to maintain attention on the road while obtaining necessary information.

[0003] However, in practical applications, the HUD system may be affected by stray light, especially from environmental light and scattering of light from the front of the vehicle. This stray light can cause reflections, interference and glare on the display screen, reducing the visibility and readability of the HUD system, and negatively affecting the driving experience and safety of the driver. Therefore, it is very important to analyze the causes of the generation of dustproof plate stray light and the light path of stray light generation during the design stage, and to adjust the design to reduce the impact of stray light in a timely manner. SUMMARY

[0005] The stray light analysis device for automobile HUD dustproof plate provided by the utility model comprises: a light source, a windshield, an eye box, a dustproof plate and a light shield; wherein,

[0006] The windshield and the light shield are rotatably connected;

[0007] The dustproof plate is arranged below the windshield and can be adjusted in angle;

[0008] The eye box is arranged below the light shield;

[0009] The eye box is provided with a light receiver;

[0010] The light source is arranged above the windshield.

[0011] In the utility model, the rear of the eye box is also provided with a light shield.

[0012] In the utility model, the size of the receiver is 300*300mm.

[0013] Preferably, according to the size of the windshield, the dust shield and the light outlet and the principle that light propagates along a straight line, the upper boundary light ray and the lower boundary light ray of the light source are connected, a plane covering the windshield is stretched along the direction of the windshield, and the light source is arranged on the plane.

[0014] The stray light analysis device of the automobile HUD light shield plate provided by the utility model, which is adjusted according to the parameters of the windshield and the dust shield provided by the automobile manufacturer, can test whether the HUD dust shield has stray light, and can quickly and accurately analyze the stray light of the HUD dust shield, so as to ensure the continuous high-quality display of the system and improve the reliability and stability of the automobile.
