[0075] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0076] The method, device, equipment and medium for determining the black area size of a vehicle side window corner according to an embodiment of the present application will be described below with reference to the accompanying drawings. In view of the problem mentioned in the above background technology that due to the lack of quantification in the black area design of the side window corner, the black area size needs to be repeatedly adjusted and corrected in the preliminary design, thereby reducing the design efficiency, the present application provides a method for determining the black area size of a vehicle side window corner. In this method, the dimension chains of the first to fourth sections are respectively decomposed. After obtaining the non-transparent area size influence factors and black area size influence factors in the first to fourth sections, based on the target styling structure of the vehicle side window corner, the minimum black area sizes of the first to fourth sections are respectively determined based on the non-transparent area size influence factors and black area size influence factors in the first to fourth sections, the difference between the minimum size and the maximum size among the minimum black area sizes of the first to fourth sections is calculated, and the final black area size and the final non-transparent area size of the first to fourth sections are determined according to the difference and a preset difference threshold. Thus, the problems that due to the lack of quantification in the black area design of the side window corner, the black area size needs to be repeatedly adjusted and corrected in the preliminary design, thereby reducing the design efficiency, etc. are solved. By decomposing the non-transparent area and the black area size of the side window corner to form a dimension chain, and by controlling the relationship between the dimension chains and determining the variables, the minimum non-transparent area size and the black area size are obtained, thereby improving the design efficiency and optimizing the visual effect.

[0077] Specifically, Figure 1 It is a schematic flowchart of a method for determining the black area size of a vehicle side window corner provided by an embodiment of the present application.

[0078] As Figure 1 shown, the vehicle side window corner includes the first to fourth sections. The first section is close to the front area of the vehicle, the second section is close to the top area, the third section is close to the bottom area of the vehicle, and the fourth section is close to the rear area of the vehicle. Among them, the method for determining the black area size of the vehicle side window corner includes the following steps:

[0079] In step S101, the dimension chains of the first to fourth sections are respectively decomposed to obtain the dimension influence factors of the first non-transparent area and the first black area in the first section, the dimension influence factors of the second non-transparent area and the second black area in the second section, the dimension influence factors of the third non-transparent area and the third black area in the third section, and the dimension influence factors of the fourth non-transparent area and the fourth black area in the fourth section.

[0080] According to an embodiment of the present application, the dimension chains of the first to fourth sections are respectively decomposed to obtain the dimension influence factors of the first non-transparent area and the first black area in the first section, the dimension influence factors of the second non-transparent area and the second black area in the second section, the dimension influence factors of the third non-transparent area and the third black area in the third section, and the dimension influence factors of the fourth non-transparent area and the fourth black area in the fourth section, including: performing a normal cutting along the boundary of the first section of the glass exposed part of the vehicle side window corner window, and decomposing the dimension chain based on the first segmentation result to obtain the gap width between the rear door trim and the corner window, the first corner window edge wrapping width, the first inner corner window edge wrapping length, the first outer corner window edge wrapping length, the distance from the first inner corner window edge wrapping to the glue application, the first glue application width, the distance from the first glue application to the sheet metal welding edge, the distance from the first sheet metal welding edge to the vehicle C-pillar trim, the thickness of the first vehicle C-pillar trim, the distance from the vehicle C-pillar trim to the black area edge of the first section, and the width of the first point area; determining the dimension influence factors of the first non-transparent area according to the gap width between the rear door trim and the corner window, the first corner window edge wrapping width, the first inner corner window edge wrapping length, the distance from the first inner corner window edge wrapping to the glue application, the first glue application width, the distance from the first glue application to the sheet metal welding edge, the distance from the first sheet metal welding edge to the vehicle C-pillar trim, the thickness of the first vehicle C-pillar trim, the distance from the vehicle C-pillar trim to the black area edge of the first section, and the width of the first point area, and obtaining the dimension influence factors of the first black area according to the first inner corner window edge wrapping length, the first outer corner window edge wrapping length, the distance from the first inner corner window edge wrapping to the glue application, the first glue application width, the distance from the first glue application to the sheet metal welding edge, the distance from the first sheet metal welding edge to the vehicle C-pillar trim, the thickness of the first vehicle C-pillar trim, the distance from the vehicle C-pillar trim to the black area edge of the first section, and the width of the first point area.

[0081] Specifically, as Figure 2As shown in the figure, the vehicle side window can be divided into four sections, namely the first section (section A), the second section (section B), the third section (section C), and the fourth section (section D). Among them, the first section is close to the front area of the vehicle side window, the second section is close to the top area of the side window, the third section is close to the bottom area of the vehicle side window, and the fourth section is close to the rear area of the vehicle side window. Thus, the size of the first non-transparent area and the first black area of the first section of the vehicle side window, the size of the second non-transparent area and the second black area of the second section, the size of the third non-transparent area and the third black area of the third section, and the size of the fourth non-transparent area and the fourth black area of the fourth section are defined respectively according to the first section, the second section, the third section, and the fourth section.

The size of the second non-transparent area of the second section is B1, which represents the distance from the lower boundary of the roof to the upper point area of the corner window. The size of the second black area of the second section is B2, which represents the distance from the upper boundary of the exposed part of the side window glass to the upper point area of the side window.

[0092] According to an embodiment of the present application, based on the target styling structure of the vehicle side window corner, the minimum black area size of the first section is determined according to the first non-transparent area size influencing factor and the first black area size influencing factor, the minimum black area size of the second section is determined according to the second non-transparent area size influencing factor and the second black area size influencing factor, the minimum black area size of the third section is determined according to the third non-transparent area size influencing factor and the third black area size influencing factor, and the minimum black area size of the fourth section is determined according to the fourth non-transparent area size influencing factor and the fourth black area size influencing factor, including: based on the target styling structure, the hemming structure of the first section, the area of the vehicle C-pillar sheet metal cavity, and the vehicle seat belt arrangement, the first influencing variable is determined according to the first non-transparent area size influencing factor and the first black area size influencing factor, and based on the target styling structure, the minimum black area size of the first section is determined according to the first influencing variable; based on the target styling structure, the hemming structure of the second section, the area of the vehicle roof sheet metal cavity, and the installation method of the seam between the vehicle C-pillar trim and the vehicle roof, the second influencing variable is determined according to the second non-transparent area size influencing factor and the second black area size influencing factor, and based on the target styling structure, the minimum black area size of the second section is determined according to the second influencing variable; based on the target styling structure, the hemming structure of the third section, the area of the vehicle C-pillar sheet metal cavity, and the installation method of the vehicle C-pillar trim, the third influencing variable is determined according to the third non-transparent area size influencing factor and the third black area size influencing factor, and based on the target styling structure and the hemming structure of the third section, the minimum black area size of the third section is determined according to the third influencing variable; based on the target styling structure, the hemming structure of the fourth section, the area of the vehicle C-pillar sheet metal cavity, and the installation method of the vehicle C-pillar trim, the fourth influencing variable is determined according to the fourth non-transparent area size influencing factor and the fourth black area size influencing factor, and based on the target styling structure and the hemming structure of the fourth section, the minimum black area size of the fourth section is determined according to the fourth influencing variable.

[0093] Specifically, based on the first non-transparent area size influencing factor A1 and the first black area size influencing factor A2 calculated above, further based on the target styling structure, the hemming structure of the first section, the area of the vehicle C-pillar sheet metal cavity, and the vehicle seat belt arrangement, the first influencing variable is determined according to the first non-transparent area size influencing factor A1 and the first black area size influencing factor A2, and based on the target styling structure, the minimum black area size of the first section is determined according to the first influencing variable. Among them, the target styling structure may include curable dimensions and non-curable dimensions. Among them, the curable dimensions in the design can be expressed as: a1 = 3.5, b1 = 3.5, e1 = 2, f1 = 8, h1 = 3, i1 = 2.5, j1 = 3, k1 = 6, and the non-curable dimensions can be expressed as: c1, d1, g1. Due to the change of the target styling structure, the dimensions of the inner hemming length c1 and the outer hemming length d1 of the first corner window of the first section will also change, such as Figure 11As shown, the hemming structure of the first section can include semi-hem and full-hem types. At the same time, affected by the area of the vehicle C-pillar sheet metal cavity and the vehicle seat belt layout, the distance g1 from the first glue application to the sheet metal welding edge will also change accordingly.

[0094] Therefore, based on the above-mentioned first non-transparent area size influence factor and first black area size influence factor of the first section, when designing the non-transparent area and black area at the front of the side window corner, it is necessary to focus on controlling the sizes of c1, d1, and g1, and try to make them the smallest sizes to obtain the smallest black area size of the first section.

Among them, the target styling structure can include curable sizes and non-curable sizes. Among them, the curable sizes in the design can be expressed as: b2 = 3.5, e2 = 2, f2 = 8, h2 = 3, i2 = 2.5, j2 = 3, k2 = 6, and the non-curable sizes can be expressed as: a2, c2, d2, g2. Due to the change of the target styling structure, the sizes of the distance a2 from the second section boundary to the hemming, the inner hemming length c2 of the second corner window, and the outer hemming length d2 of the second corner window of the second section will also change accordingly. As Figure 12 As shown, the hemming structure of the second section can include semi-hem and full-hem types. At the same time, affected by the area of the vehicle roof sheet metal cavity and the installation method of the vehicle C-pillar trim and the vehicle roof seam, the distance g2 from the second glue application to the sheet metal welding edge will also change accordingly.

[0096] Therefore, based on the above-mentioned second non-transparent area size influence factor and second black area size influence factor of the second section, when designing the non-transparent area and black area at the top of the side window corner, it is necessary to focus on controlling the sizes of a2, c2, d2, and g2, and try to make them the smallest sizes to obtain the smallest black area size of the second section.

[0097] Furthermore, based on the third non-transparent area size influence factor C1 and the third black area size influence factor C2 calculated above, further based on the target modeling structure, the edging structure of the third section, the influence of the cavity area of the C-pillar side panel of the vehicle and the installation method of the C-pillar guard plate of the vehicle, the third influencing variable is determined according to the third non-transparent area size influence factor C1 and the third black area size influence factor C2, and based on the target modeling structure, the minimum black area size of the third section is determined according to the third influencing variable, wherein the target modeling structure may include a curable size and an uncurable size, wherein the curable size during design can be expressed as: b3=3.5, e3=2, f3=8, h3=3, i3=2.5, j3=3, k3=6, and the uncurable size can be expressed as: a3, c3, d3, g3, due to the change of the target modeling structure, the size of the third section boundary to the edging distance a3, the inner edging length c3 of the third corner window and the outer edging length d3 of the third corner window of the third section will also change accordingly, such as Figure 13 As shown, the edging structure of the third section may include half-encapsulation and full-encapsulation types. At the same time, affected by the area of the vehicle's C-pillar side panel cavity and the installation method of the vehicle's C-pillar guard plate, the distance g3 from the third glue coating to the sheet metal welding edge will also change accordingly.

[0098] Therefore, based on the third non-transparent area size influencing factor and the third black area size influencing factor of the above-mentioned third segment, when designing the non-transparent area and black area in the lower part of the corner window, it is necessary to focus on controlling the sizes of a3, c3, d3 and g3, and try to achieve the smallest size to obtain the minimum black area size of the third segment.

[0099] Further, based on the fourth non-transparent area size influence factor D1 and the fourth black area size influence factor D2 calculated above, further based on the target modeling structure, the edging structure of the fourth section, the influence of the cavity area of the vehicle C-pillar side panel and the installation method of the vehicle C-pillar guard plate, the fourth influencing variable is determined according to the fourth non-transparent area size influence factor D1 and the fourth black area size influence factor D2, and based on the target modeling structure, the minimum black area size of the fourth section is determined according to the fourth influencing variable, wherein the target modeling structure may include a curable size and an uncurable size, wherein the curable size during design can be expressed as: b4=3.5, e4=2, f4=8, h4=3, i4=2.5, j4=4, k4=6, and the uncurable size can be expressed as: a4, c4, d4, g4, due to the change of the target modeling structure, the size of the fourth section from the fourth section boundary to the edging distance a4, the third corner window inner edging length c4 and the third corner window outer edging length d4 will also change accordingly, such as Figure 14 As shown, the edging structure of the fourth section may include half-encapsulation and full-encapsulation types. At the same time, affected by the area of the vehicle's C-pillar side panel cavity and the installation method of the vehicle's C-pillar guard plate, the distance g4 from the fourth glue coating to the sheet metal welding edge will also change accordingly.

[0100] Therefore, based on the fourth non-transparent area size influencing factor and the fourth black area size influencing factor of the above-mentioned fourth section, when designing the non-transparent area and the black area at the rear of the corner window, it is necessary to focus on controlling the sizes of a4, c4, d4, and g4, and try to make them the smallest sizes to obtain the smallest black area size of the fourth section.

[0101] In step S103, calculate the difference between the smallest size and the largest size among the smallest black area sizes of the first section, the second section, the third section, and the fourth section, and determine the final black area sizes and the final non-transparent area sizes of the first to fourth sections according to the difference and a preset difference threshold.

[0102] According to an embodiment of the present application, determining the final black area sizes and the final non-transparent area sizes of the first to fourth sections according to the difference and a preset difference threshold includes: determining whether the difference is greater than the preset difference threshold; if the difference is greater than the preset difference threshold, determining the target section corresponding to the smallest size, and re-adjusting the non-transparent area size influencing factor and the black area size influencing factor of the target section based on the target styling structure of the vehicle side corner window until the difference in the black area sizes between the first to fourth sections is less than the preset difference threshold, so as to obtain the final black area sizes and the final non-transparent area sizes of the first to fourth sections.

[0103] Among them, the preset difference threshold can be set by those skilled in the art according to actual test requirements, or can be obtained through a limited number of computer simulations, and no specific limitation is made here.

[0104] Specifically, among the smallest black area sizes of the first section, the second section, the third section, and the fourth section calculated above, take the difference X3 between the smallest size X2 and the largest size X1 from the first section to the fourth section, that is, X3 = X1 - X2, and determine whether the difference X3 is greater than the preset difference threshold (for example, 10). If the difference is greater than the preset difference threshold, determine the target section corresponding to the smallest size, and re-adjust the non-transparent area size influencing factor and the black area size influencing factor of the target section based on the target styling structure of the vehicle side corner window until the difference in the black area sizes between the first to fourth sections is less than the preset difference threshold, so as to obtain the final black area sizes and the final non-transparent area sizes of the first to fourth sections.

[0105] It should be noted that in order to make the black area size uniform and beautiful, it is necessary to satisfy X3 ≤ 10 during design, and the smaller X3 is, the better. When X3 is 0, the black area sizes around the side corner window are consistent, and the appearance effect is the best.

[0106] In summary, for the convenience of those skilled in the art to understand the present application more clearly, the following will be further described in conjunction with Figure 15 Next.

[0107] First, define the non-transparent area size and black area size of the first to fourth sections. The first section is close to the front area of the vehicle side window corner, the second section is close to the top area of the side window corner, the third section is close to the bottom area of the vehicle side window corner, and the fourth section is close to the rear area of the vehicle side window corner. Thus, define the first non-transparent area size and the first black area size of the first section of the vehicle side window corner, the second non-transparent area size and the second black area size of the second section, the third non-transparent area size and the third black area size of the third section, and the fourth non-transparent area size and the fourth black area size of the fourth section according to the first, second, third, and fourth sections respectively;

[0108] Secondly, perform dimension chain decomposition on the non-transparent area size and black area size of the first to fourth sections respectively, and then obtain the first non-transparent area size influence factor and the first black area size influence factor in the first section, the second non-transparent area size influence factor and the second black area size influence factor in the second section, the third non-transparent area size influence factor and the third black area size influence factor in the third section, and the fourth non-transparent area size influence factor and the fourth black area size influence factor in the fourth section. Determine the minimum black area size of the first section according to the first non-transparent area size influence factor and the first black area size influence factor, determine the minimum black area size of the second section according to the second non-transparent area size influence factor and the second black area size influence factor, determine the minimum black area size of the third section according to the third non-transparent area size influence factor and the third black area size influence factor, and determine the minimum black area size of the fourth section according to the fourth non-transparent area size influence factor and the fourth black area size influence factor;

[0109] Finally, perform integrated design on the non-transparent size and black area size of the side window corner. Based on the difference between the minimum size and the maximum size among the minimum black area size of the first section, the minimum black area size of the second section, the minimum black area size of the third section, and the minimum black area size of the fourth section, and determine the final black area size and the final non-transparent area size of the first to fourth sections according to the difference and the preset difference threshold.

[0110] In summary, according to the specific implementation manner of the embodiment of the present application, by decomposing the non-transparent area and black area size of the side window corner to form a dimension chain, and by controlling the relationship between the dimension chains and determining variables, relevant technicians can calculate the minimum non-transparent area and the minimum black area size through three-dimensional CAD (Computer-Aided Design) software, thereby improving the design efficiency of the black area of the corner window, and at the same time determining the minimum black area size of the corner window. Through integrated design, the aesthetics can be improved and the transparent area of the corner window can be increased to broaden the rear passenger's field of vision.

[0111] According to the method for determining the black area size of the vehicle side window corner of the present application, the dimension chains of the first to fourth sections are respectively decomposed. After obtaining the non-transparent area size influence factors and black area size influence factors in the first to fourth sections, based on the target styling structure of the vehicle side window corner, the minimum black area sizes of the first to fourth sections are respectively determined based on the non-transparent area size influence factors and black area size influence factors in the first to fourth sections, the difference between the minimum size and the maximum size among the minimum black area sizes of the first to fourth sections is calculated, and the final black area sizes and final non-transparent area sizes of the first to fourth sections are determined according to the difference and a preset difference threshold. Thus, the problems that the black area design of the side window corner lacks quantification, resulting in the need to repeatedly adjust and correct the black area size in the early design, and thus reducing the design efficiency are solved. By decomposing the non-transparent area and black area sizes of the side window corner to form a dimension chain, and by controlling the relationship between the dimension chains and determining variables, the minimum non-transparent area size and black area size are obtained, thereby improving the design efficiency and optimizing the visual effect.
