[0002] With the rapid development of the automobile industry, good appearance and exquisite perception have gradually become one of the important factors affecting users' purchasing desire. The rounded corners of automobile appearance are a common feature in the styling design process. The size of the rounded corners directly affects the exquisiteness of the entire vehicle. Too large rounded corners will make the product look rough, while too small rounded corners will affect visual and tactile perception. Therefore, the design of the rounded corners of automobile appearance needs to find a balance between the manufacturing process of parts and the appearance perception, so that the final product reflects the exquisite manufacturing process and high-quality appearance quality.

[0029] Reference Figure 1 According to a first aspect of the present invention, a method for detecting the fillet of vehicle exterior parts includes but is not limited to the following steps: Step S100, obtaining the fillet parameters of two mating parts. For the mating fillets of two mating parts, the parameters such as the outer diameter, the distance between the inner and outer fillet roots, etc., will affect the visual effect of whether the fillets of the mating parts are exposed and the tactile effect of whether they are uncomfortable to the hand. Therefore, the fillet parameters of the two mating parts are obtained for subsequent visual and tactile evaluation.
[0030] Step S200, obtaining a visual score based on the fillet parameters. Gaps and exposure at the fillet positions of parts will affect the visual appearance. At this time, data is obtained from the fillet parameters, and the subjective visual appearance is quantitatively evaluated and analyzed through the data, which is conducive to unified guidance and control standards.
[0031] Step S300, obtaining a tactile score based on the fillet parameters. Whether the part matching position is sharp or uncomfortable will affect the tactile sense. Similarly, obtaining data from the fillet parameters at this time and quantitatively evaluating and analyzing the subjectively perceived tactile sense through the data is conducive to unified guidance and control standards.
[0032] Step S400, obtaining a regional score based on the visual score and the tactile score. By comprehensively analyzing the visual and tactile senses, unified comparative data, namely the regional score, is obtained. The regional score can be used for direct evaluation, comparative analysis, etc. of the fillet of the part fit.
[0033] Step S500, determine whether the regional score is not less than the preset target value. When the regional score is not less than the preset target value, execute step S600 to determine that the regional score is qualified. The detection of the fillet of the part can be based on different purposes, such as longitudinal comparison and improvement of itself, or horizontal comparison of different models. According to different purposes, different target values can be preset for comparison with the regional score.
[0034] From the above, it can be seen that when it is necessary to detect the fillet of parts in one area of the vehicle, the fillets of the two mating parts in this area are analyzed visually and tactilely. Specifically, the fillet parameters of the two mating parts in the area are obtained, and visual and tactile scores are performed based on the fillet parameters, thereby obtaining the scores of the two mating areas. At this time, the area score is compared with a preset target value. The target value can be a historical value compared with itself, or an expected value that needs to be improved. When it is determined that the area score is not less than the preset target value, the area score is determined to be qualified, and the fillet detection of the two mating parts meets the standards. In this way, the detection of the fillet of parts on the vehicle appearance is systematically scored visually and tactilely, which is conducive to unifying the detection standards, improving the accuracy of detection, and better realizing the improvement and control of the fillet of parts.
[0035] In step S100, the fillet parameters include the outer diameter of the mating fillet, the distance between the root of the mating inner fillet and the root of the mating outer fillet, and obtaining the fillet parameters of two mating parts includes but is not limited to the following steps: Get the outer diameter of the mating fillet, the distance between the root of the mating inner fillet and the straight line where the root of the mating outer fillet lies of the two mating parts respectively.
[0036] In this step S100, it is necessary to obtain the outer diameters of the fillets of the two mating parts on the mating side, that is, the outer diameter of the mating fillet, and for the fillets of the two mating parts, on the side of the mating connection, it is necessary to obtain the distance between the straight line where the inner fillet root and the outer fillet root are located, that is, the distance between the straight line where the mating inner fillet root and the mating outer fillet root are located, so as to be practical for subsequent visual and tactile scoring.
[0037] like Figure 2 As shown, in step S200, a visual score is obtained according to the rounded corner parameters, including but not limited to the following steps: Step S210, calculate the absolute value of the difference between the outer diameters of the two matching fillets to obtain the first absolute value. Determine whether the first absolute value is greater than 1. When the first absolute value is greater than 1, the final output of the visual score is defined as a low score interval; when the first absolute value is less than or equal to 1, the final output of the visual score is defined as a high score interval. The lower the interval, the lower the final visual score. Conversely, the higher the interval, the higher the final visual score. When the first absolute value is greater than 1, the final output visual score value still needs to be determined according to subsequent steps, but the score of the interval is lower; and when the first absolute value is less than or equal to 1, the final output visual score value also needs to be determined according to subsequent steps, but the score of the interval will be higher.
[0038] Step S220, compare the outer diameters of the two matching fillets, the distances between the two matching inner fillet roots and the straight line where the matching outer fillet roots are located, and obtain the fillet exposure state. The first absolute value can only be used to preliminarily determine the interval state of the visual score, so in this step, determine whether the fillet is exposed, whether there is a flange, whether the boundary is exposed, etc. The fillet exposure state can be further determined by the fillet exposure state. The score corresponding to the interval state can be further determined.
[0039] Step S230, obtaining a preset visual scoring model. The visual scoring model records the corresponding scores of different visual scores and different fillet exposure states, which can provide a scoring basis for the numerical results obtained in the above steps.
[0040] Step S240 , obtaining a visual score from a visual score model according to the first absolute value and the rounded corner exposure state.
[0041] like Figure 4 and Figure 5 As shown, the two matching fillet outer diameters are PR1 and PR2 respectively, and the distances between the two matching inner fillet roots and the straight line where the matching outer fillet roots are located are D1 and D2 respectively. When comparing, the same reference line must be used, and the reference line is not between the two inner fillet roots. For example, for parts A and B, the reference line can be the connecting line of the outer fillet roots of part A, or the connecting line of the outer fillet roots of part B. In step S220, the sizes of the two matching fillet outer diameters and the numerical values of the distances between the two matching inner fillet roots and the straight line where the matching outer fillet roots are located are compared, and the fillet exposure state is obtained, including but not limited to the following steps: Step S221: When PR1<PR2 and D1<D2, or PR1>PR2 and D1>D2, the rounded corner exposure state is a high risk of exposure. At this time, the part boundary with a smaller rounded corner is in an exposed state, with the risk of flange or boundary exposure. Regardless of whether it is in the low score interval or the high score interval, the final score determined is the low score value of the interval.
[0042] Step S222: When PR1≤PR2 and D1≥D2, or when PR1≥PR2 and D1≤D2, the rounded corner exposure state is low exposure risk. At this time, the part with a smaller rounded corner has an inner boundary, and there is no risk of flange or border exposure. Regardless of whether it is in the low score interval or the high score interval, the final score determined is the high score value of the interval.
[0043] In summary of the above step S200, taking the outputted visual score of 1 to 4 as an example, the visual score is obtained from the visual score model according to the first absolute value and the rounded corner exposure state: When |PR1-PR2|>1, the final visual score output is in the low score range; when PR1<PR2 and D1<D2, or PR1>PR2 and D1>D2, the boundary of the part with smaller rounded corners is exposed, with the risk of flanging or boundary exposure, and the output visual score is 1 point; when PR1≤PR2 and D1≥D2, or PR1≥PR2 and D1≤D2, the boundary of the part with smaller rounded corners is hidden, without the risk of flanging or boundary exposure, and the output visual score is 2 points; When |PR1-PR2|≤1, the final visual score output is in the high score range; when PR1<PR2 and D1<D2, or PR1>PR2 and D1>D2, the boundary of the part with smaller rounded corners is exposed, and there is a risk of flanging or boundary exposure but it is not large, and the output visual score is 3 points; when PR1≤PR2 and D1≥D2, or PR1≥PR2 and D1≤D2, the boundary of the part with smaller rounded corners is hidden, and there is no risk of flanging or boundary exposure, and the output visual score is 4 points.
[0044] like Figure 3 As shown, in step S300, a tactile score is obtained according to the fillet parameter, including but not limited to the following steps: Step S310, calculate the absolute value of the difference between the outer diameters of the two matching fillets to obtain a second absolute value. Similarly, determine whether the second absolute value is greater than 1. When the second absolute value is greater than 1, the tactile score is finally output as a low score interval; when the second absolute value is less than or equal to 1, the tactile score is finally output as a high score interval. The lower the interval, the lower the final tactile score. Conversely, the higher the interval, the higher the final tactile score. When the second absolute value is greater than 1, the final tactile score value output at this time still needs to be determined according to subsequent steps, but the score of the interval is lower; and when the second absolute value is less than or equal to 1, the final tactile score value output also needs to be determined according to subsequent steps, but the score of the interval will be higher.
[0045] Step S320, obtaining a preset tactile scoring model. The tactile scoring model records the scores corresponding to different tactile scores, which can provide a scoring basis for the numerical results obtained in the above steps.
[0046] Step S330, obtaining a tactile score from a tactile score model according to the second absolute value. Taking a tactile score of 1 to 4 as an example: When |PR1-PR2|>1, it is necessary to further determine the values of the two fillet values. When PR1<1mm or PR2<1mm, the part boundary has a high risk of scratching hands, and the output tactile score is 1 point; when PR1≥1mm and PR2≥1mm, the part boundary has a high risk of scratching hands, and the output tactile score is 2 points; When |PR1-PR2|≤1, it is necessary to further judge the size of the two fillet values. When PR1<1mm or PR2<1mm, there is a low scratch risk at the part boundary, and the output tactile score is 3 points; when PR1≥1mm and PR2≥1mm, there is no low scratch risk at the part boundary, and the output tactile score is 4 points.
[0047] In step S400, the region score is obtained according to the visual score and the tactile score, including but not limited to the following steps: Step S410, obtaining a preset part attention level model. Parts at different locations of the vehicle will have different levels of attention to the appearance of the vehicle. Some locations have a greater impact on the appearance of the vehicle, and the regional score obtained at this time needs to account for a larger weight. Conversely, locations with less impact on the appearance of the vehicle have a smaller weight for their regional score. For example: High concern level: headlights, hood, fenders, front bumpers, front doors, rear doors, front door frames, rear door frames, side and rear triangular windows, side lights, back door lights, back door, rear bumper, charging port cover or fuel filler cap, side panels, external opening handles, instrument panel, door guards, A-pillar upper guards, large screen, left lower guard periphery, right lower guard, glove box, and auxiliary instrument panel upper cover; Medium attention level: front windshield, side panel trim, rear windshield, side end panels of the sub-panel, sub-panel armrest, rear end panel, B-pillar guard plate; Low concern level: roof cover, front fog lamps, front door sills, rear door sills, rear fog lamps, front door sill trims, rear door sill trims, C-pillar guards, back door guards, back door sill trims.
[0048] Step S420, obtaining a scoring coefficient from the part attention level model according to the two mutually matched parts. Different attention levels can be preset to correspond to different scoring coefficients, for example, a scoring coefficient corresponding to a high attention level is 10 points, a scoring coefficient corresponding to a medium attention level is 5 points, and a scoring coefficient corresponding to a low attention level is 1 point.
[0049] Step S430, according to the calculation formula The regional score is calculated, where Score the region. is the rating coefficient, For visual rating, The visual score, tactile score and the scoring coefficient of the corresponding attention level of the part are input into this calculation formula to obtain the regional score.
[0050] The regional scoring is used to score the fillet of the parts at a single position in the whole vehicle. In practical applications, the appearance of the whole vehicle can also be analyzed by combining multiple regional scores. Therefore, the present invention also includes: Step S710, obtaining multiple areas to be inspected of the vehicle appearance that need to be inspected. For example, the locations listed in the above multiple different attention levels may be inspected.
[0051] Step S720, two mutually fitting parts at corresponding positions are obtained according to the plurality of areas to be inspected. In the area to be inspected, there are two parts that cooperate with each other to form a matching fillet, so the matching fillet to be inspected is determined.
[0052] Step S730, repeatedly obtain the fillet parameters of the two mating parts, obtain the visual score according to the fillet parameters, obtain the tactile score according to the fillet parameters, and obtain the regional score according to the visual score and the tactile score. Repeat steps S100 to S400 to obtain the regional score of the detection position.
[0053] Step S740, calculating the appearance score of the whole vehicle according to the multiple area scores. After the multiple area scores are superimposed, the appearance score of the whole vehicle can be obtained.
[0054] Step S750, obtaining the vehicle appearance information according to the vehicle appearance score. The higher the vehicle appearance score, the better the appearance of the matching fillet at each position of the vehicle. In actual production, when the vehicle appearance score is too low, it is necessary to improve the assembly and production processes at multiple positions of the vehicle.
[0055] A vehicle according to an embodiment of the second aspect of the present invention is obtained by detection using the above method. The vehicle can be a private car, such as a sedan, SUV, MPV or pickup truck. The vehicle can also be an operating vehicle, such as a van, bus, small truck or large trailer. The vehicle needs to have an electric motor that can output power or store mechanical energy as a generator. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.
[0056] The above method is used to detect the fillet of the parts on the vehicle, and systematically score them through vision and touch, which is conducive to unifying the inspection standards, improving the accuracy of inspection, and better realizing the improvement and control of the fillet of the parts. It can also achieve comparative improvement of the appearance of the vehicle itself, and compare the differences between different models to improve the overall appearance of the vehicle.
