[0032] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention and facilitating its implementation.

[0033] like Figure 1As shown, the present invention provides a method for processing characteristic lines of automobile appearance parts, comprising the steps of:

[0034] S1. Collect product parameters of automobile exterior parts;

[0035] S2, setting of edge parameters of automobile exterior parts;

[0036] S3. Check the edges of automobile exterior parts after sharpening.

[0037] Specifically, if Figure 2 As shown, in the above step S1, the collected parameters of the automobile appearance part product include the edge curvature comb and chord length of the automobile appearance part product, and the collected parameters are analyzed and recorded.

[0038] The above step S2 comprises:

[0039] S201, constraining parameters for sharpening edges;

[0040] S202. After styling, comparative analysis is performed on the curvature combs.

[0041] like Figure 3 As shown, in the above step S201, the chord length and continuity of the edge line of the automobile appearance part need to be constrained.

[0042] Chord length is usually used to measure the sharpness of an edge. By setting the constraint chord length, you can ensure that the sharpness of the edge meets the design requirements and avoid the edge being too smooth or too sharp, which affects the overall visual effect and aerodynamic performance of the vehicle.

[0043] Continuity refers to the smooth transition of the edge on the surface of the vehicle body, including position continuity, tangent continuity and curvature continuity. In the design of sharp edges, continuity is particularly important because it directly affects the smoothness and aesthetics of the vehicle body surface. By ensuring the continuity of the edge, abrupt turns or unevenness on the vehicle body surface can be avoided, thereby improving the overall quality and visual effect of the vehicle. At the same time, good continuity also helps to reduce the drag coefficient and improve the fuel economy of the vehicle.

[0044] like Figure 3 As shown, in the above step S202, after modeling, the curvature comb is compared and analyzed to ensure that the edge trend of the automobile appearance part model is consistent with the edge of the automobile appearance part product, and the edge is clearer than that of the automobile appearance part product.

[0045] The above step S3 includes:

[0046] S301, check the edge position;

[0047] S302, checking edge sharpening parameters;

[0048] S303, compare curvature combs.

[0049] like Figure 4 As shown, in the above step S301, it is necessary to check whether the edge position of the automobile appearance part model is offset to ensure that the position of the edge line is consistent with the design intention. Figure 1 To.

[0050] like Figure 5 As shown, in the above step S302, it is necessary to check whether the edge sharpening parameters of the automobile appearance model meet the design requirements. The edge sharpening parameters are important indicators for evaluating edge quality, including fillet radius, chord length (i.e., detecting chord length, used to measure the sharpness of the edge) and continuity. These parameters directly affect the appearance and aerodynamic performance of the edge. Therefore, after checking the edge position, it is necessary to further check the edge sharpening parameters.

[0051] like Figure 6 As shown, in the above step S303, after the curvature comb graph is generated, the edge curvature comb of the automobile appearance part model is compared and analyzed with the edge curvature comb of the automobile appearance part product to ensure that the two are consistent. The curvature comb graphs before and after the processing are compared and analyzed, focusing on the direction, height change and location of the mutation point of the curvature comb. Through comparison, it can be evaluated whether the edge processing has a negative impact on the surface quality, or whether the expected improvement effect has been achieved.

[0052] The curvature comb is an important tool for evaluating surface quality. It can intuitively display the curvature change and direction of each point on the surface. In the processing of feature lines of automotive exterior parts, comparing the curvature comb is an important step to check the effect of edge processing. By comparing the curvature comb graphics before and after processing, the impact of edge processing on surface quality can be evaluated.

[0053] If problems are found in the quality of the processed surface, such as the curvature comb pattern is significantly different from the original product or does not meet the design requirements, timely optimization and adjustment are required.

[0054] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
