[0042] The present embodiment provides an edging member 1, which includes a first edging portion 11 and a second edging portion 12 connected to the first edging portion 11, wherein the first edging portion 11 is used to wrap a vehicle window glass 2, and the second edging portion 12 is used to overlap a vehicle body panel, and a peripheral side surface 121 of the second edging portion 12 is provided with a groove 122, and the groove 122 is used to reduce the bending force value of the second edging portion 12.

[0043] In one embodiment, the Shore A hardness of the edging piece 1 satisfies the following condition: 70 degrees ≤ A ≤ 110 degrees.

[0044] Optionally, the edge piece 1 is a plastic piece, and the material of the plastic piece includes polyurethane (PU). Specifically, the Shore A hardness of the plastic piece can be 70 degrees, or 75 degrees, or 80 degrees, or 85 degrees, or 90 degrees, or 95 degrees, or 100 degrees, or 110 degrees, etc.

[0045] The wrapping piece 1 provided in this embodiment includes a first wrapping portion 11, which is used to wrap the vehicle window glass 2. The first wrapping portion 11 can support the vehicle window glass 2 and play a sealing role. Among them, the vehicle window glass 2 can be a skylight glass, a front windshield, a rear windshield, or a side window glass, etc. The vehicle window glass 2 can be a single-piece glass, a double-piece laminated glass, or a hollow glass, etc.

[0046] The hemming piece 1 provided in this embodiment further includes a second hemming portion 12 for overlapping the vehicle body panel. The second hemming portion 12 can also be understood as a tongue of the hemming piece 1. Optionally, the second hemming portion 12 is bent and connected to the first hemming portion 11.

[0047] Alternatively, if Figure 1 As shown, the length H5 of the second hemming portion 12 satisfies the following condition: 5mm≤H5≤15mm. Specifically, the length H5 of the second hemming portion 12 can be 5mm, or 6mm, or 7mm, or 8mm, or 9mm, or 10mm, or 11mm, or 12mm, or 13mm, or 14mm, or 15mm, etc.

[0048] Alternatively, if Figure 1 As shown, the thickness H6 of the second hemming portion 12 satisfies the following condition: 1mm≤H6≤2mm. Specifically, the thickness H6 of the second hemming portion 12 can be 1mm, or 1.1mm, or 1.2mm, or 1.3mm, or 1.4mm, or 1.5mm, or 1.6mm, or 1.7mm, or 1.8mm, or 1.9mm, or 2mm, etc.

[0049] The peripheral side surface 121 includes an appearance surface 1211 and a mounting surface 1212 that are arranged opposite to each other, the appearance surface 1211 is used to face the outside, and the mounting surface 1212 is used to overlap the vehicle body panel. The peripheral side surface 121 of the second hemming portion 12 is provided with a groove 122. For example, the groove 122 is provided on the mounting surface 1212. For another example, the groove 122 is provided on the appearance surface 1211. For another example, the groove 122 is provided on the mounting surface 1212 and the appearance surface 1211.

[0050] In one embodiment, the groove 122 is provided on the mounting surface 1212. By providing the groove 122 on the mounting surface 1212, the resistance of the edging member 1 overlapping the vehicle body panel is reduced, the difficulty of assembly is reduced, and the appearance surface 1211 is avoided to be affected, thereby improving the appearance of the vehicle. In addition, the mounting surface 1212 needs to fit with the vehicle body panel. From the perspective of the mounting structure, the mounting surface 1212 needs to be deformed, so the groove 122 is provided on the mounting surface 1212, which can partially weaken the second edging portion 12, so that the mounting surface 1212 of the second edging portion 12 is more easily fitted with the vehicle body panel.

[0051] In one implementation, the opening width H3 of the groove 122 satisfies the following condition: H3 ≥ 0.5 mm; the depth H4 of the groove 122 satisfies the following condition: 0.2 mm ≤ H4 ≤ 0.6 mm.

[0052] Specifically, if Figure 3 As shown, the opening width H3 of the groove 122 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc. The depth H4 of the groove 122 can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, etc.

[0053] This embodiment limits the opening width H3 of the groove 122 to 0-0.5mm and the depth H4 of the groove 122 to 0.2mm-0.6mm, which not only reduces the bending force value of the second edging portion 12 and makes the second edging portion 12 easier to bend, but also ensures the strength of the second edging portion 12 itself and ensures the reliability of the edging piece 1.

[0054] The number of the grooves 122 is one or more. For example, one to four grooves 122 are provided on the second hemming portion 12. Optionally, the plurality of grooves 122 are arranged at intervals along the direction from the second hemming portion 12 to the first hemming portion 11. Optionally, the plurality of grooves 122 are arranged at intervals along the circumferential direction of the second hemming portion 12.

[0055] It should be noted that the lap force value is mainly determined by the bending deformation of the second edging portion 12. The edging piece 1 provided in this embodiment reduces the bending force value of the second edging portion 12 and increases the bending deformation of the second edging portion 12 by setting a groove 122 in the second edging portion 12, thereby reducing the lap resistance.

[0056] Specifically, since the peripheral side surface 121 of the second hemming portion 12 is provided with a groove 122, the groove 122 can reduce the bending force value of the second hemming portion 12, making the second hemming portion 12 easier to bend, thereby reducing the resistance of the second hemming portion 12 overlapping the body panel, reducing the installation force of the hemming piece 1 overlapping, and thus reducing the assembly difficulty of the hemming piece 1 overlapping the body panel, improving the assembly efficiency, improving the matching effect of the window glass 2, the hemming piece 1, and the body panel, and improving the appearance of the vehicle. In addition, it can also reduce the gap between at least part of the hemming piece 1 and the body panel, improve the wind noise phenomenon of the vehicle, and improve the use experience of the vehicle.

[0057] In addition, by providing a plurality of grooves 122, the second edging portion 12 is weakened in multiple sections, and the second edging portion 12 is more easily fitted with the vehicle body panel in multiple sections, further reducing the gap after at least part of the edging piece 1 is overlapped with the vehicle body panel, further improving the wind noise phenomenon of the vehicle, and further improving the vehicle's user experience.

[0058] Therefore, this embodiment reduces the resistance of the edging piece 1 overlapping the vehicle body panel by setting a groove 122 in the second edging portion 12 of the edging piece 1, reduces the difficulty of assembly, improves the matching effect between the edging piece 1 and surrounding components, and improves the wind noise phenomenon of the vehicle.

[0059] Please refer to Figure 1-Figure 5 In one embodiment, there is a connection between the first edge portion 11 and the second edge portion 12, and the groove 122 is arranged close to the connection.

[0060] The connection between the first hemming portion 11 and the second hemming portion 12 can also be understood as the root of the second hemming portion 12, and the end of the second hemming portion 12 away from the first hemming portion 11 can also be understood as the head of the second hemming portion 12. The groove 122 is arranged near the connection, which can also be understood as the groove 122 being arranged near the root of the second hemming portion 12.

[0061] By providing the groove 122 in the second hemming portion 12, the strength of the second hemming portion 12 itself is reduced, so that the strength of the second hemming portion 12 is weakened at the position where the groove 122 is provided. When the second hemming portion 12 overlaps the vehicle body panel, the force on the vehicle body panel starts from the head of the second hemming portion 12, and the vehicle body panel is deformed according to the moment. The larger the force arm, the easier it is to deform. Therefore, the farther the groove 122 is from the head of the second hemming portion 12, the easier it is to deform. In other words, the closer the groove 122 is to the root of the second hemming portion 12, the lower the bending force value of the second hemming portion 12 can be.

[0062] Therefore, this embodiment further reduces the resistance of the edging member 1 overlapping the vehicle body panel by arranging the groove 122 close to the connection, further reduces the difficulty of assembly, further improves the matching effect between the edging member 1 and surrounding components, and further improves the wind noise phenomenon of the vehicle.

[0063] In one embodiment, the distance H1 between the groove 122 and the connection portion satisfies the following condition: 0≤H1≤5mm. Figure 1 As shown, the spacing H1 between the groove 122 and the connection can be 0, or 0.1mm, or 0.2mm, or 0.3mm, or 0.4mm, or 0.5mm, or 0.6mm, or 0.7mm, or 0.8mm, or 0.9mm, or 1mm, or 1.1mm, or 1.2mm, or 1.3mm, or 1.4mm, or 1.5mm, or 1.6mm, or 1.7mm, or 1.8mm, or 1.9mm, or 2mm, or 2.5mm, or 3mm, or 3.5mm, or 4mm, or 4.5mm, or 5mm, etc.

[0064] There are multiple grooves 122 , and a distance H1 between the groove 122 closest to the first edge portion 11 and the connection portion satisfies the following condition: 0≤H1≤5mm.

[0065] Please refer to Figure 1-Figure 5 In one embodiment, the number of the grooves 122 is multiple, and the multiple grooves 122 are arranged at intervals along the direction from the second edge portion 12 to the first edge portion 11.

[0066] The plurality of grooves 122 are arranged at intervals along the direction from the second hemming portion 12 to the first hemming portion 11, which can also be understood as the plurality of grooves 122 being arranged at intervals along the axial direction of the second hemming portion 12. Among the plurality of grooves 122, the groove 122 closest to the connection is the end groove 122, and the spacing between the end groove 122 and the connection is 0-2 mm.

[0067] In this embodiment, a plurality of grooves 122 are arranged along the direction of the second edging portion 12 pointing to the first edging portion 11, so that the second edging portion 12 is weakened in multiple sections in the axial direction, further reducing the resistance of the edging member 1 overlapping the vehicle body panel, further reducing the difficulty of assembly, and making it easier for the second edging portion 12 to achieve multi-section bonding with the vehicle body panel, further reducing the gap after at least part of the edging member 1 overlaps the vehicle body panel, further improving the wind noise phenomenon of the vehicle, and further improving the vehicle use experience.

[0068] In one embodiment, the distance H2 between two adjacent grooves 122 satisfies the following condition: 0<H2≤1.5mm.

[0069] Optionally, the spacing between any two adjacent grooves 122 is equal. Figure 3 As shown, the distance H2 between two adjacent grooves 122 can be 0.1 mm, or 0.2 mm, or 0.3 mm, or 0.4 mm, or 0.5 mm, or 0.6 mm, or 0.7 mm, or 0.8 mm, or 0.9 mm, or 1 mm, or 1.1 mm, or 1.2 mm, or 1.3 mm, or 1.4 mm, or 1.5 mm, etc.

[0070] Please refer to Figure 1-Figure 5 In one embodiment, the groove 122 satisfies one of the following conditions: Figure 4 As shown, the groove 122 includes a first groove side wall and a second groove side wall that are oppositely disposed, and the first groove side wall and the second groove side wall are connected to form a sharp angle.

[0071] One end of the first groove sidewall away from the opening of the groove 122 is connected to one end of the second groove sidewall away from the opening of the groove 122 to form a sharp angle. The shape of the groove 122 can also be understood as a triangle, or a nearly triangle.

[0072] and / or, if Figure 5 As shown, the groove 122 includes a groove bottom wall, and the groove bottom wall is an arc surface that bulges in a direction away from the opening of the groove 122 .

[0073] The bottom wall of the groove is an arc-shaped curved surface, convex in a direction away from the opening of the groove 122. The shape of the groove 122 can also be understood as an arch, or a nearly arch.

[0074] This embodiment limits the shape of the groove 122 , which can reduce the bending force of the second edge portion 12 and make the second edge portion 12 easier to bend, while ensuring the strength of the second edge portion 12 itself and the reliability of the edge member 1 .

[0075] In order to make the purpose and advantages of the present application clearer, the effects of the edging member 1 of the present application are further described in detail below in conjunction with specific embodiments.

[0076] Verification 1:

[0077] like Figure 1 As shown, in embodiments 1-9, the grooves 122A, 122B, 122C, and 122D are obtained by different combinations. The grooves 122A, 122B, 122C, and 122D are arranged in sequence on the peripheral side surface 121 of the second hemming portion 12 along the arrangement direction of the second hemming portion 12 pointing to the first hemming portion 11. The groove 122A is farthest from the connection between the first hemming portion 11 and the second hemming portion 12, and the groove 122D is closest to the connection between the first hemming portion 11 and the second hemming portion 12. The opening widths of the grooves 122 of the grooves 122A, 122B, 122C, and 122D are all ≥0.5mm, and the depths of the grooves 122 are all 0.2mm. The length of the second hemming portion 12 is less than 10mm, and the thickness is 1mm-1.5mm.

[0079] The second hemming portion 12 in the first embodiment is provided with a groove 122A. The second hemming portion 12 in the second embodiment is provided with a groove 122B.

[0080] The second hemming portion 12 in the third embodiment is provided with a groove 122C. The second hemming portion 12 in the fourth embodiment is provided with a groove 122D.

[0083] The second hemming portion 12 in the ninth embodiment is provided with a groove 122A, a groove 122B, a groove 122C, and a groove 122D.

[0084] Specifically, the verification simulation results of the edge wrapping member 1 provided in Comparative Example 1 and Examples 1-9 are as follows: Figure 6-Figure 10As shown, the specific parameters of the hemming member 1 provided by the comparative example 1 and the embodiments 1-9 are shown in the following table 1. Among them, the bending force value of the second hemming portion 12 refers to the minimum force required to bend and deform the second hemming portion 12. The reduction rate refers to the percentage of the difference between the bending force value of the second hemming portion 12 of the embodiment and the bending force value of the second hemming portion 12 of the comparative example to the bending force value of the second hemming portion 12 of the comparative example.

[0085] Table 1 Specific parameters of the edge wrapping parts provided in Comparative Example 1 and Examples 1-9

[0086] Second hemming bending force value (N / 10mm) Reduction rate (%) Comparative Example 1 0.259 / Example 1 0.255 1.54 Example 2 0.252 2.70 Example 3 0.247 4.63 Example 4 0.236 8.88 Example 5 0.246 5.02 Example 6 0.218 15.83 Example 7 0.243 6.18 Example 8 0.216 16.60 Example 9 0.214 17.37

[0087] From the data of comparative example 1 and embodiments 1-4 in Table 1, it can be seen that the arrangement of the groove 122 near the connection between the first hemming portion 11 and the second hemming portion 12 can significantly reduce the lap resistance value. Moreover, the closer the position of the groove 122 is to the connection, the greater the impact on the second hemming portion 12. In addition, from the data of embodiments 4, 5, and 7 in Table 1, it can be seen that the position of the groove 122 has a greater impact on the force value than the number of grooves 122.

[0088] From the data of comparative example 1 and embodiments 1-9 in Table 1, it can be seen that the technical solution of embodiment 9 has the greatest improvement on the lap resistance value of the second hemming portion 12, with a reduction rate of up to 17.37%, which can effectively improve the lap resistance value.
