Automobile, checking method for reflected light of instrument panel of automobile on front door glass and manufacturing method for automobile

Abstract

The invention discloses a checking method for the reflected light of an instrument panel of an automobile on front door glass. The method comprises the steps that an eye ellipse is made; tangents of the eye ellipse are made through a point on the mirror surface of a rearview mirror; front door glass acts as a reflecting surface, and reflection lines of all the tangents are made; and when all the reflection lines are not intersected with an indication surface of the instrument panel or all the reflection lines are not intersected with the indication surface of the instrument panel due to the fact that the reflection lines are blocked by a light blocking part, the reflected light of the instrument panel on front door glass does not influence visual lines of a driver for observing the rearview mirror. The invention also provides a manufacturing method for the automobile and the automobile. The aforementioned checking method is simple and easy to operate, and the reflected light of the instrument panel on front door glass can be checked in the design process of the automobile so that optimization can be timely performed in the design process, the situation that the reflected light of the instrument panel on front door glass influences the visual lines of the driver for observing the rearview mirror of the side at night is prevented, driving comfort degree is facilitated for the driver and driving safety is enhanced.

Description

Technical field [0001] The present invention relates to the field of automobile design and manufacturing, in particular, to a method for checking the reflected light of an automobile dashboard on the front door glass, and also to a method for manufacturing an automobile and an automobile including the checking method. Background technique [0002] When the driver observes the rearview mirror on the driver's side, the line of sight needs to pass through the front door glass on the driver's side. Therefore, the corresponding area of ​​the front door glass must not have any obstructions and bright lights that affect the driver's vision. [0003] At present, automobile dashboards, pointers, scales, etc. usually have a self-luminous function, and some meters have background lights so that the driver can clearly see the display of the meters during driving at night. But in the process of driving at night, the light emitted by the instrument in the car will shine on the front door glass o...

Problems solved by technology

But in the process of driving at night, the light emitted by the instrument in the car will shine on the front door glass on the driver's side and form an image. It will make it difficult for the driver to observe the rearview mirror and affect driving safety.

[0004] Although there is a shield between the combined instrument and the front door glass of the car, such as an instrument cover to block the light, if the height of the instrument cover is improper, or the position of the instrument or rearview mirror is improperly set, the above-mentioned problems will still occur. The above factors are often ignored in the design process of some cars, which brings serious safety hazards to the driver's night driving safety.
