Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a rear door side sealing strip structure and automobile. Background Technology

[0002] Currently, when the rear doors of automobiles have a door-wrapped side panel structure, wheel rim sealing strips are added for sealing to block rainwater and sand splashed by the rear wheels. However, the length of the wheel rim sealing strip only covers the circumference of the wheel arch, leaving the sheet metal exposed directly from the window frame to the upper end of the wheel rim without any sealing strip coverage. This exposed sheet metal edge, adhesive surface, and secondary step surface negatively impacts the perceived quality of opening the door, and the large gap between the door sheet metal and the outer side panel results in significant wind noise, hindering the improvement of the vehicle's overall NVH (noise, vibration, and harshness) performance. Furthermore, the lack of sealing strips at the B-pillar seam between the front and rear door outer panels affects the perceived quality of the appearance, contributing to increased wind noise and further hindering the improvement of the vehicle's NVH performance.

[0003] Therefore, there is an urgent need for a rear door side sealing strip structure and automobile to solve the above problems. Utility Model Content

The inner door panel 11 is fixed to the side of the outer door panel 12 facing the interior of the vehicle body 6.

[0039] The first sealing strip 2 is connected to the inner edge of the rear end of the rear door 1. Along the height direction of the rear door 1, the top end of the first sealing strip 2 extends above the outer water cut of the rear door 1, and the bottom end extends to the bottom end of the rear door 1. The second sealing strip 3 covers the front end of the rear door 1, and the bottom end extends to the bottom end of the rear door 1, while the top end extends upward to the middle of the B-pillar in the height direction.

[0040] The rear door side sealing strip structure provided in this embodiment has a first sealing strip 2 located on the inner edge of the rear end of the rear door 1. This seal is used to achieve a complete seal between the rear door 1 and the outer water-cutting edge when the rear door 1 is closed, solving the wind noise problem caused by the large gap between the outer side panel 61 of the vehicle body 6 and the rear door 1, thus improving the overall NVH (Noise, Vibration, Harshness) performance of the vehicle. Furthermore, the top of the first sealing strip 2 extends above the outer water-cutting edge of the rear door 1, providing some coverage to the fixing screws of the outer water-cutting edge and improving the aesthetics of the rear door 1. The second sealing strip 3 covers the front end of the rear door 1; that is, part of the second sealing strip 3 is located inside the front end of the rear door 1, and part is located outside the front end of the rear door 1. This seal is used to seal the gap between the front door 4 and the rear door 1 under the B-pillar when the front door 4 is closed, preventing wind noise problems caused by this gap and improving the aesthetics of the area.

[0041] Optionally, such as Figure 1 and Figure 2As shown, the first sealing strip 2 includes a first corner 21, a rear sealing section 22, a second corner 23, a wheel rim sealing section 24, and a third corner 25 connected to the inner door panel 11.

The first corner 21 serves to seal the top of the rear sealing section. Due to the different sheet metal structures of the rear sealing section 22 and the wheel rim sealing section 24, their cross-sections are different, and the second corner 23 serves as a transition connection between the rear sealing section 22 and the wheel rim sealing section 24. The third corner 25 seals the bottom of the wheel rim sealing section 24.

[0042] In this embodiment, both the rear sealing section 22 and the wheel rim sealing section 24 are extruded bubble tube structures. The first corner 21, the second corner 23, and the third corner 25 are all injection molded parts, and are all fixed to the inner door panel 11 by a third clip and 3M adhesive. Among them, the first corner 21 has a larger area to better cover the external water-cutting mounting screws and improve the perceived quality of the rear door 1 when the door is opened.

[0043] Furthermore, such as Figure 1 and Figure 2 As shown, the wheel rim sealing section 24 includes a Y-shaped tube 241 and a first lip 242. Both the Y-shaped tube 241 and the first lip 242 extend along the extension direction of the wheel rim sealing section 24. The Y-shaped tube 241 has three sharp corners, including a first sharp corner 2411, a second sharp corner 2412, and a third sharp corner 2413. The first lip 242 is connected to the first sharp corner 2411. A first buckle 243 is provided on the first lip 242, connecting the first lip 242 to the inner door panel 11. Multiple first buckles 243 are spaced apart along the extension direction of the wheel rim sealing section 24. The first lip 242 facilitates the connection between the wheel rim sealing section 24 and the rear door 1. The second sharp corner 2412 abuts against the inner rear edge of the rear door 1, and the third sharp corner 2413 abuts against the outer side panel 61 of the vehicle body 6 when the rear door 1 is closed. In other words, when the rear door 1 is closed, the second sharp corner 2412 and the third sharp corner 2413 of the Y-shaped tube 241 abut against the inner edge of the rear end of the rear door 1 and the outer side panel 61 of the body 6, respectively, thereby achieving a seal between the rear wheel flange area of ​​the rear door 1 and the body 6.

[0044] Furthermore, such as Figure 1 and Figure 3As shown, the rear sealing section 22 includes an O-ring 221 extending along the extension direction of the rear sealing section 22. A second latch 222 is provided on the O-ring 221, with one end of the second latch 222 located inside the O-ring 221 and the other end latched onto the inner door panel 11. When the rear door 1 is closed, the rear door 1 presses against the O-ring 221, sealing the gap between the wheel rim area of ​​the rear door 1 and the vehicle body 6. Multiple second latches 222 are spaced apart along the extension direction of the O-ring 221.

[0045] Furthermore, such as Figure 1 and Figure 3 As shown, the rear sealing section 22 also includes a second lip 223 connected to the O-ring 221 and extending along the extension direction of the O-ring 221. The second lip 223 is located on the side of the O-ring 221 near the rear edge of the rear door 1, and the end of the second lip 223 away from the O-ring 221 abuts against the inner door panel 11. When the rear door 1 is closed, the O-ring 221 abuts against the outer side panel 61, thereby achieving a seal between the area above the rear wheel flange of the rear door 1 and the vehicle body 6. The second lip 223 serves to cover the gap between the O-ring 221 and the inner door panel 11, and also to a certain extent covers the rounded corners of the inner door panel 11 sheet metal.

[0046] Optionally, such as Figure 4 and Figure 5 As shown, the second sealing strip 3 includes a fourth corner 31, a front sealing section 32, and a fifth corner 33. The fourth corner 31 is connected to the top end of the front sealing section 32, and the fifth corner 33 is connected to the bottom end of the front sealing section 32. The fourth corner 31 is used to seal the top end of the front sealing section 32, and the fifth corner 33 is used to seal the bottom end of the front sealing section 32.

[0047] In this embodiment, the front sealing section 32 is an extruded bubble tube, and the fourth corner 31 and the fifth corner 33 are both injection molded parts. The fourth corner 31 and the fifth corner 33 are both fixed to the inner door panel 11 by the fourth buckle.

[0048] Furthermore, such as Figure 4 and Figure 5As shown, the front sealing section 32 includes a covering portion 321 and a third lip 322 extending along the extending direction of the front sealing section 32. The covering portion 321 covers the front edge of the rear door 1.

That is, the third lip 322 is connected to the side of the covering portion 321 facing the outer side of the rear door 1 and is connected to the edge of the covering portion 321 on that side. The front sealing section 32 is configured such that when the front door 4 is closed, the other end of the third lip 322 extends to the inner side of the front door 4 and abuts against the rear end of the front door 4. The covering part 321 covers the front edge of the rear door 1 to connect the front sealing section 32 and the rear door 1. The third lip 322 covers the gap between the rear door 1 and the front door 4 under the B-pillar, that is, the gap between the front and rear doors. The rear door edge coating 13 is also covered to improve the appearance and the quality of the door opening perception, reduce wind advance, and improve the NVH performance of the whole vehicle.

[0049] Furthermore, such as Figure 4 and Figure 5 As shown, the third lip 322 abuts against the front end of the rear door 1 at one end, near the outer edge of the front end face of the rear door 1. This allows the third lip 322 to cover unsightly surfaces such as sheet metal folds, glued surfaces, and secondary step surfaces at the front end of the rear door 1, improving the aesthetics of the front end of the rear door 1 and reducing the noise when the rear door is opened.

[0050] Furthermore, such as Figure 4 and Figure 5 As shown, the front sealing section 32 also includes a fourth lip 323 extending along the extension direction of the front sealing section 32. One end of the fourth lip 323 in the width direction is fixedly connected to the portion of the covering part 321 located inside the rear door 1, and the other end abuts against the inner side of the rear door 1, thereby blocking the gap between the side of the covering part 321 away from the third lip 322 and the rear door 1.
