Problems solved by technology

Due to differences in lighting conditions and engineers’ development experience, the subjective evaluation of paint effects deviates greatly. It is impossible to scientifically and systematically evaluate the subjective perception effects of automotive paints. It is not until the actual vehicle spraying stage that the paint perception effects are found to be poor. The development cycle is long and the effect is not good.
At present, there is no systematic evaluation in the laboratory stage, and the subjective evaluation is based on the actual vehicle spraying

Embodiment 1

[0029] Installation of the evaluation device of embodiment 1

[0030] like figure 1 As shown, the evaluation device consists of three parts: the base box, the observation adjustment module and the lighting module;

[0031] like figure 2 As shown, the base box 1 is in the shape of a cube, the inner wall is sprayed with neutral gray paint, the upper end is open, and a corner is cut off from the upper front part as the observation window 11. The size of the lighting module is consistent with the opening of the upper end of the base box; The base box terminal installation hole 12 and the knob terminal installation hole 14 are arranged symmetrically;

[0032] like Figure 3-8 As shown, the observation adjustment module is composed of a color palette tray 2, an observation adjustment knob 7, a knob connection terminal 5, a base box connection terminal 3 and a fastening nut 4; A rectangular standard swatch slot 21 is symmetrically arranged, and a terminal interface 22 is respect...

Abstract

The invention belongs to the field of automobile coating development and particularly relates to a portable device for subjective assessment on an automobile coating effect. At an experimental stage, scientific and systematic subjective assessment on the automobile coating effect is achieved. The portable device for subjective assessment on the automobile coating effect is composed of a basic box, an observation adjusting module and an illuminating module. The basic box is in a cubic shape, and the upper end is open and is provided with an observation window. The observation adjusting module consists of a color palette tray, an observation adjusting rotary knob, a rotary knob connecting terminal, a basic box connecting terminal and a fastening nut. The illuminating module consists of a basic box cover plate, a batter box, an LED lamp and a light source switch knob. The portable device can simulate indoor and outdoor illuminating conditions and provide highlight, front-side and bottom-color observing visual angles and meanwhile achieves contrastive analysis of two gradient color palettes.

Description

technical field [0001] The invention belongs to the field of automobile paint development, and in particular relates to a portable subjective evaluation device for the effect of automobile paint. Background technique [0002] At present, in the experimental stage of automotive paint development, there is a lack of systematic methods and devices for subjective evaluation of paint effects. Due to differences in lighting conditions and engineers’ development experience, the subjective evaluation of paint effects deviates greatly. It is impossible to scientifically and systematically evaluate the subjective perception effects of automotive paints. It is not until the actual vehicle spraying stage that the paint perception effects are found to be poor. The development cycle is long and the effect is not good. . At present, there is no systematic evaluation in the laboratory stage, and the evaluation is based on subjective feeling when spraying the real car. Contents of the inv...
