Design method of combination instrument, combination instrument and vehicle

Abstract

The invention provides a design method of a combination instrument, the combination instrument and a vehicle. The design method includes the following steps: obtaining an eye ellipse according to a vehicle model design hard spot, wherein the eye ellipse is located in a visible area of the combination instrument; adjusting the curvature radius and/or installation angle of a face cover of the combination instrument to make the curvature center of the face cover to be located above the visible upper limit of the visible area; selecting an incident point above the eye ellipse; adjusting the brim of the combination instrument to make reflected rays formed after the face cover of the combination instrument reflects the incident rays which are formed between the incident point and the lowest point of the face cover of the combination instrument are blocked by the brim of the combination instrument. The design method enables drivers to clearly observe information on dial plates, and accordingly avoids complaints from users and improves user experience.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a design method of a combination meter, the combination meter and a vehicle. Background technique [0002] The car combination meter cover is a part of the combination meter, and many models currently use a concave shape mask. When the driver is in the driving position, since the combination instrument cover is similar to a concave lens, according to the principle of reflection, the driver’s body parts or clothes will appear on the mask, especially some bright clothes, which will affect the driver’s understanding of the information displayed on the combination instrument. Reading will have a bad effect on the quality of the product. [0003] At present, some models use new materials to reduce the degree of mask imaging to achieve the purpose of reducing the impact. However, only some luxury models use new materials to reduce the impact of instrument mask imaging. Due to the...

When the driver is in the driving position, since the combination instrument cover is similar to a concave lens, according to the principle of reflection, the driver’s body parts or clothes will appear on the mask, especially some bright clothes, which will affect the driver’s understanding of the information displayed on the combination instrument. Reading, which will have a bad influence on the quality of the product

[0003] At present, some models use new materials to reduce the degree of mask imaging to achieve the purpose of reducing the impact. However, only some luxury models use new materials to reduce the impact of instrument mask imaging. Due to the high cost, and the impact of suppliers' technical capabilities and supply capabilities, many low-end and mid-end models have not been adopted, and the scope of application is limited.
