Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of design and manufacturing of automobile parts, in particular to an outer panel of a rear wheel housing and a vehicle. Background Art
[0002] For a body structure without an exterior wheel arch structure at the rear wheel housing part, for the aesthetic appearance of the styling, it is usually required that the outer panel of the side wall and the rear bumper have two flush surfaces, and the R angle at the seam part is relatively small. Generally, the R angle of the outer panel of the side wall is designed to be 1.25 mm. For the stability of the rear bumper after installation, the rear bumper bracket needs to have a certain thickness, generally about 30 mm to meet sufficient performance requirements. The outer CAS surface of the outer panel of the side wall and the outer CAS surface of the rear bumper are on the same smooth plane, and the bumper bracket mounting surface of the outer panel of the side wall is in contact with the lower plane of the rear bumper bracket. Therefore, the seam position between the outer panel of the side wall and the rear bumper wheel housing needs to have the same thickness as the rear bumper assembly.
[0003] To ensure the sealing performance after gluing at the joint between the outer panel of the side wall and the outer panel of the rear wheel housing, a bonding position design is adopted between the outer panel of the side wall and the outer panel of the rear wheel housing; at the seam part between the outer panel of the side wall and the rear bumper, the outer panel of the rear wheel housing is designed to follow the shape of the outer panel of the side wall as a whole, and the maximum gap at the upper and lower corner parts is ≤ 3 mm; a 1 mm gap is designed between the large surfaces for easy assembly.
[0004] The existing rear bumper installation structure has the following problems:
[0005] The upper and lower surfaces of the outer panel of the rear wheel housing are in contact with the outer panel of the side wall, and the forming depth and forming angle of the outer panel of the wheel housing at this position are the same as those of the outer panel of the side wall, which will cause difficulties in forming the outer panel of the rear wheel housing. Cracking or hidden cracking is likely to occur at this position, thus affecting the quality of the whole vehicle.
[0006] At the seam part between the outer panel of the side wall and the rear bumper, because the R angle of the outer panel of the side wall is 1.25 mm, the R at the upper and lower corner positions of the outer panel of the rear wheel housing needs to be R = 6 mm to meet the sealing requirements under the condition of ensuring glue application sealing; however, a 6 mm R angle will cause difficulties in forming the outer panel of the rear wheel housing. Cracking or hidden cracking is likely to occur at this position, thus affecting the quality of the whole vehicle.
[0007] In summary, at the seam between the outer panel of the side wall and the rear bumper, the glue application sealing performance and stamping formability between the outer panel of the rear wheel housing and the outer panel of the side wall cannot be ensured simultaneously. Summary of the Utility Model
[0008] The utility model aims to solve at least the technical problem that the glue application sealing performance and stamping formability between the outer panel of the rear wheel housing and the outer panel of the side wall cannot be ensured simultaneously at the seam between the outer panel of the side wall and the rear bumper in the prior art.
[0009] To this end, an object of the present utility model is to provide an outer panel of a rear wheel housing, which includes a main body of the outer panel of the rear wheel housing and a hemming surface, a bending surface, a transition vertical surface, and a rear bumper positioning avoidance surface provided on the inner side of the main body of the outer panel of the rear wheel housing;
[0010] The hemming surface and the bending surface are arranged in parallel, and the hemming surface is arranged outside the bending surface; the bending surface is connected to the inner side of the main body of the outer panel of the rear wheel housing, and the lower part of the bending surface is connected to the transition vertical surface through an R corner, and one side of the transition vertical surface is connected with the rear bumper positioning avoidance surface.
[0011] Furthermore, the outer edges of the hemming surface, the transition vertical surface, and the rear bumper positioning avoidance surface are connected to form a trimming line.
[0012] Furthermore, the trimming line at the transition vertical surface is parallel to the R corner line between the bending surface and the transition vertical surface.
[0013] Furthermore, the trimming line at the transition vertical surface is smoothly connected to the rear bumper positioning avoidance surface.
[0014] Furthermore, the trimming line at the rear bumper positioning avoidance surface forms a notch for setting a rear bumper positioning hole.
[0015] Furthermore, connection points for installing an outer panel of a side wall are provided on the upper and lower sides of the notch.
[0016] Furthermore, at the rear bumper split part, the gaps between the upper and lower corner parts of the outer panel of the rear wheel housing and the outer panel of the side wall are all ≤ 3 mm.
[0017] Furthermore, rear bumper positioning holes are provided on the outer panel of the side wall.
[0018] Furthermore, the distances between the trimming line at the rear bumper positioning avoidance surface and the rear bumper positioning holes are all ≥ 7 mm.
[0019] Furthermore, the distance between the trimming line at the rear bumper positioning avoidance surface and the boundary of the outer panel of the side wall is ≥ 7 mm.
[0020] The present utility model provides a vehicle, which includes the above-mentioned outer panel of the rear wheel housing.
[0021] The outer panel of the rear wheel housing and the vehicle of the present utility model have the following beneficial effects:
[0022] By connecting a bending surface inside the main body of the outer panel of the rear wheel housing, a positioning avoidance surface for the rear bumper is arranged on one side of the transition vertical surface. The trimming line at the transition vertical surface is parallel to the R-corner edge line between the bending surface and the transition vertical surface, and is smoothly connected between the trimming line at the transition vertical surface and the positioning avoidance surface for the rear bumper. The trimming line at the positioning avoidance surface for the rear bumper forms a notch for setting the positioning hole for the rear bumper, thereby reducing the size of the transition vertical surface and the forming depth, while ensuring the stamping forming process and the sealing performance after gluing.

[0047] The hemming surface 101 and the bending surface 102 are arranged in parallel with each other, and the hemming surface 101 is provided on the outer side of the bending surface 102; the bending surface 102 is connected to the inner side of the outer panel main body 106 of the rear wheel housing, the lower part of the bending surface 102 is connected to the transition vertical surface 103 through an R corner, and one side of the transition vertical surface 103 is connected with the rear bumper positioning avoidance surface 104.
[0048] Specifically, the R corner is used to represent the transition fillet at the intersection of the bending surface 102 and the transition vertical surface 103.
[0049] In the present utility model, a bending surface 102 is connected to the inner side of the outer panel body 106 of the rear wheel housing, and a positioning and avoiding surface 104 for the rear bumper is arranged on one side of the transition vertical surface 103, thereby reducing the size of the transition vertical surface, decreasing the forming depth, and ensuring the sealing performance after stamping and gluing.
[0050] Embodiment 2
[0051] As Figure 4 and Figure 5 shown, this embodiment provides an outer panel for a rear wheel housing, which includes an outer panel body 106 of the rear wheel housing and a hemming surface 101, a bending surface 102, a transition vertical surface 103, and a positioning and avoiding surface 104 for the rear bumper arranged on the inner side of the outer panel body 106 of the rear wheel housing;
[0052] The hemming surface 101 and the bending surface 102 are arranged in parallel, and the hemming surface 101 is arranged on the outer side of the bending surface 102; the bending surface 102 is connected to the inner side of the outer panel body 106 of the rear wheel housing, and the lower part of the bending surface 102 is connected to the transition vertical surface 103 through an R corner, and a positioning and avoiding surface 104 for the rear bumper is connected to one side of the transition vertical surface 103;
[0053] The outer edges between the hemming surface 101, the transition vertical surface 103, and the positioning and avoiding surface 104 for the rear bumper are connected to form a trimming line 105, and the trimming line 105 at the positioning and avoiding surface 104 for the rear bumper forms a notch for arranging a rear bumper positioning hole 201; the trimming line 105 at the transition vertical surface 103 is parallel to the R corner edge line between the bending surface 102 and the transition vertical surface 103, and the trimming line at the transition vertical surface 103 is smoothly connected to the positioning and avoiding surface 104 for the rear bumper.
[0054] In the present utility model, a bending surface 102 is connected to the inner side of the outer panel body 106 of the rear wheel housing, a positioning and avoiding surface 104 for the rear bumper is arranged on one side of the transition vertical surface 103, the trimming line 105 at the transition vertical surface 103 is parallel to the R corner edge line between the bending surface 102 and the transition vertical surface 103, the trimming line at the transition vertical surface 103 is smoothly connected to the positioning and avoiding surface 104 for the rear bumper, and the trimming line 105 at the positioning and avoiding surface 104 for the rear bumper forms a notch for arranging a rear bumper positioning hole 201, thereby reducing the size of the transition vertical surface, decreasing the forming depth, and ensuring the sealing performance after stamping and gluing.
[0055] In the prior art, the stamping forming depth of the outer panel of the rear wheel housing at the split seam between the outer panel of the side wall and the rear bumper is the depth from the hemming surface to the positioning and avoiding surface for the bumper. At this time, the depth is about 30 mm.
[0056] In the present utility model, the stamping depth is the distance from the R corner where the bending surface 102 intersects the transition vertical surface 103 to the trimming line. This R corner is designed to be 6 mm, and the R corner is parallel to the trimming line with a distance ≥ 5 mm (meeting the requirements of glue application and sealing). The minimum stamping depth can be achieved as 6 + 5 = 11 mm, greatly reducing the stamping depth of the outer panel of the rear wheel housing 100 at the seam between the outer panel of the side wall and the rear bumper; when the stamping depth is low enough, the hemming surface and the transition vertical surface can be designed to be 6 mm, and at this time, the glue application and sealing requirements of ≤ 3 mm at the upper and lower corners of the outer wheel housing can be met.
[0057] Specifically, at the seam of the rear bumper, the gaps between the main body 106 of the outer panel of the rear wheel housing and the upper and lower corners of the outer panel 200 of the side wall are all ≤ 3 mm, meeting the requirements of glue application and sealing.
[0058] It solves the problem that at the seam between the outer panel 200 of the side wall and the rear bumper, the glue application sealing performance and the stamping formability between the outer panel 100 of the rear wheel housing and the outer panel 200 of the side wall cannot be ensured simultaneously.
[0059] Embodiment 3
[0060] As Figure 4 and Figure 5 shown, this embodiment provides an outer panel of a rear wheel housing, including a main body 106 of the outer panel of the rear wheel housing and a hemming surface 101, a bending surface 102, a transition vertical surface 103, and a rear bumper positioning and avoiding surface 104 arranged inside the main body 106 of the outer panel of the rear wheel housing;
[0061] The hemming surface 101 and the bending surface 102 are arranged parallel to each other, and the hemming surface 101 is arranged outside the bending surface 102; the bending surface 102 is connected to the inside of the main body 106 of the outer panel of the rear wheel housing, and the lower part of the bending surface 102 is connected to the transition vertical surface 103 through an R corner, and one side of the transition vertical surface 103 is connected with a rear bumper positioning and avoiding surface 104;
[0062] The outer edges between the hemming surface 101, the transition vertical surface 103, and the rear bumper positioning and avoiding surface 104 are connected to form a trimming line 105, and the trimming line 105 at the rear bumper positioning and avoiding surface 104 forms a notch for arranging the rear bumper positioning hole 201; the trimming line 105 at the transition vertical surface 103 is parallel to the R corner edge line between the bending surface 102 and the transition vertical surface 103, and the trimming line at the transition vertical surface 103 is smoothly connected to the rear bumper positioning and avoiding surface 104.
[0063] In the present utility model, a bent surface 102 is connected to the inner side of the outer panel body 106 of the rear wheel housing. The rear bumper positioning avoidance surface 104 is arranged on one side of the transition vertical surface 103. The trimming line 105 at the transition vertical surface 103 is parallel to the R - corner edge line between the bent surface 102 and the transition vertical surface 103. The trimming line at the transition vertical surface 103 is smoothly connected to the rear bumper positioning avoidance surface 104. The trimming line 105 at the rear bumper positioning avoidance surface 104 forms a notch for setting the rear bumper positioning hole 201, thereby reducing the size of the transition vertical surface, lowering the forming depth, and at the same time ensuring the stamping forming process and the sealing performance after gluing.
[0064] In the prior art, the stamping forming depth of the outer panel of the rear wheel housing at the split seam between the outer panel of the side wall and the rear bumper is the depth from the hemming surface to the bumper positioning avoidance surface. At this time, the depth is about 30 mm.
[0065] In the present utility model, the stamping forming depth is the distance from the R - corner where the bent surface 102 intersects with the transition vertical surface 103 to the trimming line. This R - corner is designed to be 6 mm, the R - corner is parallel to the trimming line and the distance ≥ 5 mm (meeting the requirements of gluing and sealing). The minimum stamping forming depth can be achieved as 6 + 5 = 11 mm, greatly reducing the stamping forming depth of the outer panel 100 of the rear wheel housing at the split seam between the outer panel of the side wall and the rear bumper. When the stamping depth is low enough, the hemming surface and the transition vertical surface can be designed to be 6 mm, and at this time, the gluing and sealing requirements of ≤ 3 mm at the upper and lower corners of the wheel housing can be met.
[0066] At the split seam of the rear bumper, the gaps between the outer panel body 106 of the rear wheel housing and the upper and lower corner parts of the outer panel 200 of the side wall are all ≤ 3 mm, meeting the requirements of gluing and sealing.
[0067] The difference between this embodiment and the second embodiment lies in:
[0068] As Figures 1 - 3 shown, connection points for installing the outer panel 200 of the side wall are arranged on the upper and lower sides of the notch formed by the trimming line 105 at the rear bumper positioning avoidance surface 104. The radius of the connection points is preferably 6.5 mm.
[0069] Specifically, the rear bumper positioning avoidance surface 104 and the outer panel 200 of the side wall are connected by welding at the connection points, preferably spot welding, which can strengthen the connection strength between the outer panel 200 of the side wall and the outer panel 100 of the rear wheel housing.
[0070] The outer panel 200 of the side wall is provided with a rear bumper positioning hole 201 for positioning the rear bumper.
[0071] To ensure there is enough gluing surface, the distance between the trimming line 105 at the rear bumper positioning avoidance surface and the boundary of the outer panel 200 of the side wall needs to be ≥ 7 mm, and for the parts that cannot be avoided locally, the distance can be 5 mm; the distance between the trimming line 105 at the rear bumper positioning avoidance surface and the rear bumper positioning hole 201 needs to be ≥ 7 mm to avoid the phenomenon that the gluing contaminates the rear bumper positioning hole 201 due to too small a distance.
[0072] It solves the problem that the gluing sealing performance and stamping formability cannot be ensured simultaneously at the joint between the outer panel of the side wall and the rear bumper and between the outer panel of the rear wheel housing and the outer panel 200 of the side wall.
[0073] Embodiment 4
[0074] As Figure 4 and Figure 5 shown, this embodiment provides an outer panel of a rear wheel housing, which includes a main body 106 of the outer panel of the rear wheel housing and a hemming surface 101, a bending surface 102, a transition vertical surface 103 and a rear bumper positioning avoidance surface 104 arranged inside the main body 106 of the outer panel of the rear wheel housing;
[0075] The hemming surface 101 and the bending surface 102 are arranged in parallel, and the hemming surface 101 is arranged outside the bending surface 102; the bending surface 102 is connected to the inside of the main body 106 of the outer panel of the rear wheel housing, and the lower part of the bending surface 102 is connected to the transition vertical surface 103 through an R corner, and a rear bumper positioning avoidance surface 104 is connected to one side of the transition vertical surface 103;
[0076] The outer edges between the hemming surface 101, the transition vertical surface 103 and the rear bumper positioning avoidance surface 104 are connected to form a trimming line 105, and the trimming line 105 at the rear bumper positioning avoidance surface 104 forms a notch for setting the rear bumper positioning hole 201; the trimming line 105 at the transition vertical surface 103 is parallel to the R corner edge line between the bending surface 102 and the transition vertical surface 103, and the trimming line at the transition vertical surface is smoothly connected to the rear bumper positioning avoidance surface 104.
[0077] In the present utility model, by connecting the bending surface 102 inside the main body 106 of the outer panel of the rear wheel housing, arranging the rear bumper positioning avoidance surface 104 on one side of the transition vertical surface 103, making the trimming line 105 at the transition vertical surface 103 parallel to the R corner edge line between the bending surface 102 and the transition vertical surface 103, smoothly connecting the trimming line at the transition vertical surface to the rear bumper positioning avoidance surface 104, and forming a notch for setting the rear bumper positioning hole 201 at the trimming line 105 at the rear bumper positioning avoidance surface 104, the size of the transition vertical surface is reduced, the forming depth is lowered, and at the same time, the stamping formability and the sealing performance after gluing are ensured.
[0078] In the prior art, the stamping depth of the outer panel of the rear wheel housing at the joint between the outer panel of the side wall and the rear bumper is the depth from the hemming surface to the positioning and avoiding surface of the bumper. At this time, the depth is about 30 mm;
[0079] In the present utility model, the stamping depth is the distance from the R corner where the bending surface 102 intersects with the transition vertical surface 103 to the trimming line. This R corner is designed to be 6 mm, and the R corner is parallel to the trimming line and the distance ≥ 5 mm (meeting the requirement of glue application and sealing). The minimum stamping depth can be achieved as 6 + 5 = 11 mm, greatly reducing the stamping depth of the outer panel 100 of the rear wheel housing at the joint between the outer panel of the side wall and the rear bumper; when the stamping depth is low enough, the hemming surface and the transition vertical surface can be designed to be 6 mm, and at this time, the glue application and sealing requirement of ≤ 3 mm at the upper and lower corners of the wheel housing can be met.
[0080] At the joint part of the rear bumper, the gaps between the main body 106 of the outer panel of the rear wheel housing and the upper and lower corner parts of the outer panel 200 of the side wall are all ≤ 3 mm, meeting the requirement of glue application and sealing.
[0081] The difference between this embodiment and the above embodiments lies in:
[0082] The outer panel of the rear wheel housing is of an integral structure.
[0083] The bending surface 102 is a one-time bending surface.
[0084] Both the bending surface 102 and the hemming surface 101 are of arc-shaped structures, which are adapted to the shape of the vehicle tire.
[0085] Lifting lugs are provided on the main body 106 of the outer panel of the rear wheel housing. The number of lifting lugs is two. By providing the lifting lugs, it is easy to install the outer panel of the rear wheel housing onto the side wall assembly, avoiding the problem of inconvenient installation in the prior art.
[0086] The outer panel of the rear wheel housing is made of materials such as engineering plastics or aluminum alloy. Engineering plastics have strong wear resistance and impact resistance, and are relatively lightweight, with low manufacturing costs, and can be customized according to vehicle models and colors. Therefore, they are widely used in fields such as automobiles, electric vehicles, and motorcycles; the aluminum alloy outer panel of the wheel housing is lightweight, has strong oxidation resistance, and can fully display the high-quality design of the vehicle.
[0087] The outer panel 200 of the side wall is made of aluminum alloy outer panel. Aluminum alloy is a lightweight, high-strength, and corrosion-resistant material. Compared with steel, the density of aluminum alloy is smaller, and the weight is about 30% lighter, which is beneficial to the lightweight design of the vehicle and improving fuel economy.
[0088] The outer panel 200 of the side wall is made of high-strength steel outer panel. The high-strength steel outer panel has the characteristics of high strength and wear resistance, and can provide excellent collision safety protection. It has higher anti-bending and tensile properties, and can ensure the strength and stiffness of the vehicle body while achieving the lightweight of the vehicle body.
[0089] The outer side panel 200 is made of a composite material outer panel. Composite material outer panels are often made of materials such as carbon fiber, glass fiber, and organic polymers, and have the characteristics of light weight, high strength, good stiffness, and corrosion resistance. In the body design of some high-end vehicles, using a composite material outer side panel can improve the quality and performance of the entire vehicle.
