Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a side drainage channel assembly, a vehicle body, and a vehicle. Background Technology

[0002] The vehicle's side panel drainage system includes an outer side panel and a drainage channel. In the prior art, the outer side panel and the drainage channel are connected and fixed by a flange structure. Due to design and manufacturing limitations, the included angle between the top section and the side panel of the outer side panel deviates from the angle of the flange structure of the drainage channel. The overlap width is narrow, the structural dimensional tolerance requirements are high, and there is a risk of poor overlap and water leakage. In the installed state, there is a cavity in some areas between the outer side panel and the drainage channel, which requires the installation of cavity partitions and sealing, resulting in increased costs and weak overall structural strength. During road testing, this area is prone to structural cracking, water leakage, and abnormal noise.

[0003] Therefore, for side-mounted water channel components, how to simplify the overall structure, ensure structural stability and sealing, and reduce costs are technical problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this application is to provide a side drainage channel assembly, a vehicle body, and a vehicle that can simplify the overall structure of the side drainage channel assembly, ensure structural stability and sealing, and reduce costs.

[0005] To address the aforementioned technical problems, this application provides a side-mounted water channel assembly, comprising a side-mounted outer panel and a water channel assembly; the side-mounted outer panel encloses a top section and a side section, the rear end face of the top section forms a first overlapping surface, and the inner wall surface of the side section forms a second overlapping surface, the second overlapping surface being located on the rear side of the top section; the water channel assembly comprises a water channel body and an extension, the front end of the water channel body is provided with a third overlapping surface, and the extension includes a first mating surface, a second mating surface, and a third mating surface, the first mating surface being used to engage and fix with the first overlapping surface, the second mating surface being used to engage and fix with the second overlapping surface, and the third mating surface being used to engage and fix with the third overlapping surface.

[0006] The specific structure and angle of the three mating surfaces of the extension can be set according to the actual structure and angle of the first, second, and third overlapping surfaces. In other words, by adapting the extension to the structure of the side panel and the water trough body, the overlap width between the mating surfaces and overlapping surfaces that are fixed together can reach 10mm. Compared with the existing technology where the overlap width is no more than 5mm, the overlap stability is better. Furthermore, the mating surfaces and overlapping surfaces can be fixed by spot welding and sealant after mating, which is flexible and adaptable, and can ensure the overall sealing and structural stability of the side panel water trough assembly.

[0007] Compared to the existing technology where the side panel is directly fixed to the water trough body, this method avoids gaps between the overlapping and mating surfaces, eliminates the need for empty walls to seal the gaps and ensure the airtightness between the side panel and the water trough body, simplifies the overall structure, improves structural quality, reduces costs, and ensures the stability of the overall structure.

[0008] Optionally, the rear top of the side panel segment arches outward toward the outer side of the side panel to form a first reinforcement, and the inner wall surface of the first reinforcement forms the second overlapping surface.

The second reinforcing part is provided on the side facing the extension.

The fourth mating surface is used to cooperate and fix with the second overlapping surface, and the fourth mating surface is located behind the second mating surface.

[0014] Optionally, the flanged portion is provided with a fixing area, which is located on the side corner of the flanged portion away from the extension and the water trough body. The fixing area is fixed with a fixing bracket, and the side outer panel is also fixed with a connecting platform; the fixing bracket and the connecting platform are connected.

[0051] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] This application provides a side drainage channel assembly, a vehicle body, and a vehicle, wherein the vehicle includes a vehicle body, and the vehicle body includes the side drainage channel assembly, such as... Figure 1 As shown, the side wall water channel assembly includes a side wall outer plate 1 and a water channel assembly. The water channel assembly includes a water channel body 2 and an extension 3, with the extension 3 connected between the side wall outer plate 1 and the water channel body 2.

[0053] Specifically, such as Figure 2 As shown, the side panel 1 includes a top section 11 and a side panel section 12. The top section 11 is located above the side panel section 12, and the rear end of the side panel section 12 extends beyond the rear side of the top section 11 to form a mounting notch 13 at the top rear side of the side panel 1. The top section 11 and the rear end face form a first overlapping surface 14, that is, the side wall surface of the mounting notch 13 forms the first overlapping surface 14. The inner wall surface of the side panel section 12 forms a second overlapping surface 15, which is located behind the top section 11. Specifically, the bottom inner wall surface of the mounting notch 13 forms the second overlapping surface 15.

[0054] The front end of the water tank body 2 is provided with a third overlapping surface 21 (such as...). Figure 3 As shown), Figure 4 As shown, the extension 3 forms three mating surfaces on different side edges through a flange structure. These three mating surfaces are the first mating surface 31, the second mating surface 32, and the third mating surface 33. The first mating surface 31 is used to mate and fix with the first overlapping surface 14, the second mating surface 32 is used to mate and fix with the second overlapping surface 15, and the third mating surface 33 is used to mate and fix with the third overlapping surface 21.

[0055] The specific structure and angle of the three mating surfaces of the extension 3 can be set according to the actual structure and angle of the first overlapping surface 14, the second overlapping surface 15, and the third overlapping surface 21. That is to say, by adapting the structure of the extension 3 to the side panel 1 and the water trough body 2, the overlap width between the mating surfaces and the overlapping surfaces that are fixed to each other can reach 10mm. Compared with the existing technology where the overlap width is no more than 5mm, the overlap stability is better. Furthermore, after the mating surfaces and the overlapping surfaces are mated, they can be fixed by spot welding and sealant 8, which is flexible and adaptable, and can ensure the overall sealing and structural stability of the side panel water trough assembly.

[0056] Compared to the existing technology where the side panel 1 and the water trough body 2 are directly fixed, this method avoids gaps between the overlapping and mating surfaces, eliminates the need for empty walls to seal the gaps and ensure the airtightness between the side panel 1 and the water trough body 2, simplifies the overall structure, improves the perceived quality (PQ) of the structure, reduces costs, and ensures the stability of the overall structure.

[0057] like Figure 7 and Figure 8 As shown, the sidewall of the mounting notch 13 has a first face 141 and a second face 142. The first face 141 and the second face 142 form a preset angle and together form the first overlapping surface 14. The first mating surface 31 corresponding to the extension 3 includes a third face 311 and a fourth face 312. Specifically, the first face 141 and the third face 311 are fitted and fixed together by spot welding and sealant 8. A preset gap d is provided between the second face 142 and the fourth face 312. The size of the preset gap d is not required, such as 0.3mm-0.6mm, preferably 0.5mm. The preset gap d is filled with sealant to seal and fix the second face 142 and the fourth face 312 by sealant 8, so as to ensure the sealing and stability between them.

[0058] This configuration effectively ensures the connection strength and stability between the first overlapping surface 14 and the first mating surface 31. One set of surfaces is fitted and fixed, while the other set of surfaces has a preset gap d between them, which is sealed and fixed by filling with sealant. This effectively solves the problem of overlap interference caused by tolerance exceeding tolerance, and ensures the sealing performance of the connection between the first overlapping surface 14 and the first mating surface 31 and the overall vehicle PQ.

[0059] In this embodiment, the preset included angle is not limited, and can be 90°, 110°, 120°, etc. Preferably, the included angle between the third face 311 and the fourth face 312 is the same as the preset included angle to avoid excessively large local gaps and facilitate installation. Preferably, as... Figure 6 and Figure 7 As shown, the first face 141 is an upward-facing face, the second face 142 is a rearward-facing face, and the first overlapping face 14 is located outside the first mating face 31 to ensure the vehicle's NVH performance.

[0060] like Figure 2 , Figure 6 and Figure 8 As shown, the rear top of the side panel segment 12 arches outward toward the outer side panel 1 to form a first reinforcing part 16, that is, the bottom of the mounting notch 13 arches outward to form the first reinforcing part 16. The inner wall surface of the first reinforcing part 16 forms the aforementioned second overlapping surface 15. The provision of the first reinforcing part 16 can increase the structural strength of the outer side panel 1 at this location. Furthermore, due to the provision of the first reinforcing part 16, the second overlapping surface 15 is positioned further outward relative to the first overlapping surface 14. In this way, while ensuring that the mating area between the second overlapping surface 15 and the second mating surface 32 remains unchanged, the bottom of the second mating surface 32 also extends outward.

[0061] like Figure 5 As shown in the figure, the dashed line a1 represents the position of the front edge of the second mating surface 32 when the side outer panel 1 does not have the first reinforcing part 16, and the solid line a2 represents the position of the front edge of the second mating surface 32 when the side outer panel 1 has the first reinforcing part 16. The dimension h between the front edge of the first mating surface 31 and the front edge of the second mating surface 32 is clearly reduced when the side outer panel 1 has the first reinforcing part 16. This reduction in dimension h can effectively avoid the process problem of wrinkling during the molding of the extension 3. The specific reduction in dimension is related to the outward arching height of the first reinforcing part 16, which is not specifically limited here. Preferably, the outward arching height of the first reinforcing part 16 is set to 2mm.

[0062] like Figure 1 and Figure 2 As shown, the rear upper part of the side panel 1 is also provided with a rear corner window mounting area 18. The rear corner window mounting area 18 is used to install the rear corner window 4 and is provided with a hole structure 181. The rear corner window mounting area 18 is partially arched outward along the edge of the hole structure 181 to form a second reinforcing part 17. The second reinforcing part 17 is located on the side facing the extension 3, that is, on the side facing the mounting notch 13.

[0063] By providing the first reinforcing part 16 and the second reinforcing part 17, the structural strength of the side panel 1 in the rear top area can be increased, ensuring the overall structural stability of the side panel 1. This effectively avoids the problem of plastic deformation of the side panel 1 during installation and transportation.

[0064] The rear corner window mounting area 18 is provided with a snap-fit ​​structure 182, such as... Figure 1 and Figure 2 As shown, the snap-fit ​​structure 182 is used to fix the rear corner window 4 by snap-fit ​​engagement. When the rear corner window 4 is installed in the rear corner window mounting area 18, the rear corner window 4 can cover the rear corner window mounting area 18, the first reinforcing part 16 and the second reinforcing part 17, ensuring the overall structure of the side water channel assembly is neat and can also enhance the overall aesthetics.

[0065] like Figure 9 As shown, the rear corner window 4 is also provided with a lip 41, and the extension 3 is also provided with an overlap groove 34 (such as...). Figure 4 As shown), with the rear corner window 4 installed on the side outer panel 1 via the snap-fit ​​structure 182, the lip 41 overlaps with the overlapping groove 34. The arrangement of the lip 41 and the overlapping groove 34 facilitates the installation of the rear corner window 4.

[0066] like Figure 4 As shown, the extension 3 forms the first mating surface 31 by providing a first flange structure 35, the second mating surface 32 by providing a second flange structure 36, and the third mating surface 33 by providing a third flange structure 37. The first mating surface 31 is formed on the outer surface of the first flange structure 35, the second mating surfaces 32 are all formed on the outer surface of the second flange structure 36, and the third mating surface 33 forms the inner surface of the corresponding flange structure. Specifically, in this embodiment, the forming process of each flange structure is not limited. For example, the flange structure can be formed by folding the side of the extension 3, or the extension 3 can be integrally formed with the above-mentioned flange structures by stamping.

[0067] like Figure 2 As shown, the third overlapping surface 21 at the front end of the water tank body 2 is set to face rearward. During assembly, the third flange structure 37 is overlapped above the front end of the water tank body 2, so that the third mating surface 33 can mate with the third overlapping surface 21. The third mating surface 33 can be fixed to the third overlapping surface 21 by spot welding and sealant 8.

[0068] like Figure 1 As shown, when the third mating surface 33 and the third overlapping surface 21 are fixed together, a seam 9 is formed between the third flange structure 37 and the front end of the water channel body 2. Figure 10 As shown, the water channel assembly also includes a trim panel 5, which can be fixed to the water channel body 2. When the trim panel 5 and the water channel body 2 are in a fixed state, the trim panel 5 can cover the seam 9, ensuring the integrity and aesthetics of the overall structure and improving the overall vehicle quality.

[0069] like Figure 2As shown, the side of the water trough body 2 facing the outer side panel 1 is also provided with a flange 22. The outer wall surface of the flange 22 forms a fourth mating surface 221. The fourth mating surface 221 is used to cooperate and fix with the second overlapping surface 15, and the fourth mating surface 221 is located behind the second mating surface 32. That is, the front part of the second overlapping surface 15 is fixed with the second mating surface 32, and the rear part of the second overlapping surface 15 is fixed with the fourth mating surface 221. The front end of the water trough body 2 is fixed with the outer side panel 1 through the extension 3. At the same time, the water trough body 2 is also directly fixed with the second overlapping surface 15 of the outer side panel 1 through the fourth mating surface 221 formed by the flange 22. This arrangement can further ensure the fixation stability between the water trough body 2 and the outer side panel 1.

[0070] And, as Figure 3 As shown, a transition section 223 is also formed on the front side of the flanged portion 22. This transition section 223 is located inside the extension portion 3. The second flanged structure 36 can cover the transition section 223 from above, ensuring the sealing and connection stability of the joint. In this embodiment, there are no restrictions on the fixing method between the transition section 223 and the second flanged structure 36. For example, it can be fixed by spot welding and sealant 8, or it can be fixed by structural adhesive.

[0071] The flanged portion 22 of the water tank body 2 is also provided with a fixing area 222. The fixing area 222 is located on the side corner of the fourth mating surface 221 away from the extension 3 and the water tank body 2. The fourth mating surface 221 of the flanged portion 22 mates with the second overlapping surface 15 and is fixed by spot welding and sealant 8. The transition section 223 at the front end of the flanged portion 22 can mate with the second flanged structure 36 of the extension 3 to avoid warping and ensure stability. The fixing area 222 on the rear side of the flanged portion 22 can be fixed by welding or structural adhesive to ensure stability.

[0072] Specifically, it could be like this Figure 3 and Figure 11 As shown, a fixing bracket 23 is fixedly installed in the fixing area 222, and a connecting platform 19 is also fixedly installed in the outer side panel 1 (e.g., Figure 2 As shown), the fixed bracket 23 can be connected to the connecting platform 19 (as shown). Figure 12 As shown in the diagram, the fixing bracket 23 can be welded to the connecting platform 19, and the sealant 8 can be used to further ensure the stability and sealing of the fixing. In other words, by setting the fixing bracket 23 to the connecting platform 19 and fixing it with sealant 8 in the fixing area 222 of the flange 22, the connection strength between the flange 22 and the outer side panel 1 is ensured, preventing the flange from warping and ensuring the sealing of the area.

[0073] In this embodiment, the specific structure of the fixing bracket 23 is not limited; the fixing bracket 23 can be as follows: Figure 3 As shown, it includes a first connecting part 231 and a second connecting part 232, wherein one end of the second connecting part 232 is fixed to the first connecting part 231, and the fixing bracket 23 is approximately Y-shaped. The first connecting part 231 is fixed to the flanged part 22 of the water tank body 2 by spot welding and sealant 8. After the first connecting part 231 and the flanged part 22 are fixed by spot welding and sealant 8, the fourth mating surface 221 is welded to the second overlapping surface 15 and fixed, and the second connecting part 232 is fixed to the fixing bracket 23 by spot welding and sealant 8.

[0074] Or, it could also be like Figure 13 As shown, the flanged portion 22 does not have a fixing bracket 23, and the side panel 1 does not need a connecting platform 19. The fixing area 222 of the flanged portion 22 is directly connected to the side panel 1, such as by bonding the fixing area 222 to the side panel 1 with structural adhesive. That is to say, as Figure 14 As shown, the fixing area 222 of the flange 22 is bonded and fixed to the outer side panel 1 with structural adhesive to ensure the connection strength between the flange 22 and the outer side panel 1, prevent warping, and ensure the sealing of the area.

[0075] like Figure 15 As shown, the bottom of the water trough body 2 is also provided with a hinge mounting hole 24 for installing the tailgate hinge. The water trough body 2 is fixed to the side panel 1 by the flange 22. The hinge mounting hole 24 is away from the connection seam between the side panel 1 and the water trough body 2. During the opening and closing of the tailgate, the opening and closing force of the support rod is transmitted to the bottom of the water trough body 2 through the tailgate hinge, such as... Figure 15 As shown by the middle arrow, the water trough body 2 transmits force F to the D-pillar reinforcing plate 6, and through the three-way structure of the D-pillar reinforcing plate 6, the force is transmitted to the C-pillar, D-pillar, and the rear crossbeam of the top cover. This arrangement reduces the connection strength requirement between the water trough body 2 and the side panel 1. Compared to the scheme where the hinge mounting hole 24 is located on the side wall of the water trough body 2, this significantly reduces the strength requirement of the side wall of the water trough body 2, thereby reducing the thickness requirement of the side wall of the water trough body 2. For example, when the hinge mounting hole is located on the side wall of the water trough body 2 in the prior art, the side wall thickness of the water trough body 2 is about 0.9mm. However, in this embodiment, when the hinge mounting hole 24 is located on the bottom wall of the water trough body 2, the side wall thickness of the water trough body 2 can be set to 0.65mm, which effectively reduces the overall weight, facilitates lightweight design, and reduces costs.

[0076] like Figure 16 As shown, the main body 2 of the water tank is also equipped with a mounting bracket 25. In the installed state, as... Figure 18As shown, the mounting bracket 25 is located within the cavity formed between the water tank body 2, the side outer panel 1, and the D-pillar reinforcing plate 6. A cavity partition 10, formed by foaming, encloses the mounting bracket 25 within the cavity, effectively blocking airflow within the cavity formed by the D-pillar cavity, the C-pillar cavity, and the upper beam area. The airflow between these cavities is as follows: Figure 17 and Figure 19 As shown, this improves the overall NVH (Noise, Vibration, Harshness) performance of the vehicle.

[0077] Specifically, this embodiment does not limit the specific structure of the mounting bracket 25, such as... Figure 16 As shown, the mounting bracket 25 includes a first fixing part 251 and a second fixing part 252. The first fixing part 251 and the second fixing part 252 are generally L-shaped and can be formed by bending an integral structure. The first fixing part 251 is fixed to the water tank body 2, specifically by spot welding and sealant 8. The second fixing part 252 is used to snap and fix to each section of the cavity. The mounting bracket 25 has a simple structure and is convenient for arranging the cavity partition 10.

[0078] In the attached diagram, weld point 7 is located where fixation is achieved through spot welding. Figure 11 and Figure 13 As shown, the second overlapping surface 15 and the second mating surface 32 of the extension 3, as well as the second overlapping surface 15 and the fourth mating surface 221 of the flanged part 22 of the water tank body 2, are fixed by spot welding and sealant 8, and multiple welding points 7 are formed.
