[0033] The door sheet metal 100 is the main structure of the door, and the door sheet metal 100 includes a door outer panel 101 and a door inner panel 102 , and the side panel metal 200 is the supporting structure of the entire vehicle.

[0034] The first embodiment of the present invention provides a vehicle door gap sealing structure, such as Figure 1 As shown, the door gap sealing structure is installed on the inner side of the door sheet metal 100, where the inner side refers to the side facing the interior of the vehicle. Compared with installing the door gap sealing structure at the joint 300 between the door sheet metal 100 and the side panel metal 200, the door gap sealing structure here is hidden inside the door sheet metal 100, which can protect it from direct sunlight and reduce the degree of erosion by rainwater. The door gap sealing structure is less affected by external factors, has a longer anti-aging life, and extends its service life, thereby improving the sealing effect. At the same time, the door gap sealing structure is hidden inside the door sheet metal 100, avoiding its exposure to the outside, which can improve the aesthetics of the joint 300 between the door sheet metal 100 and the side panel metal 200.

[0035] The door gap sealing structure includes a sealing strip body 1, with a first water retaining flange 2 and a second water retaining flange 3 provided on both sides of the top of the sealing strip body 1. The two sides of the top of the sealing strip here refer to the side close to the door sheet metal 100 and the side close to the side panel sheet metal 200. The first water retaining flange 2 extends toward the side panel sheet metal 200 and is connected to the side panel sheet metal 200, and the second water retaining flange 3 extends toward the door sheet metal 100 and is connected to the door sheet metal 100. Figure 2 As shown, the first water retaining flange 2 can reduce the possibility of rainwater and the like entering the vehicle along the door sheet metal 100, and the second water retaining flange 3 can also reduce the possibility of rainwater and the like entering the vehicle along the door sheet metal 100. In addition, the first water retaining flange 2 and the second water retaining flange 3 can also block mud and water stains that are incidental to driving, preventing them from being thrown into the door gap, thereby ensuring a good sealing effect.

[0036] The first water-retaining flange 2 and the second water-retaining flange 3 on the sealing strip body here form a first sealing area near the joint 300. Rainwater or dust can be blocked in the first sealing area between the first water-retaining flange 2 and the second water-retaining flange 3, and discharged from the bottom of the vehicle along the first sealing area under the action of gravity, thereby ensuring the sealing performance of the vehicle at the door frame stop between the door sheet metal 100 and the side panel sheet metal 200.

[0037] Among them, the first water retaining flange 2 and the second water retaining flange 3 are U-shaped structures, which can effectively prevent rain and dust outside the car door from entering the inside of the car door. In addition, when observed from the outside of the car, the first water retaining flange 2 and the second water retaining flange 3 are a black seam, which makes the car more streamlined and more beautiful.

[0038] In other embodiments, the first water retaining flange 2 and the second water retaining flange 3 are V-shaped structures.

[0039] The interference between the first water retaining flange 2 and the side panel 200 is 1-2 mm. For example, the interference between the first water retaining flange 2 and the side panel 200 is 1.3 mm. The interference between the second water retaining flange 3 and the door panel 100 is 2-4 mm. For example, the interference between the second water retaining flange 3 and the door panel 100 is 2.1 mm. Here, the first water retaining flange 2 and the side panel 200 are overlapped, and the second water retaining flange 3 and the door panel 100 are overlapped. When the first water retaining flange 2 is washed by rainwater, the overlap between the first water retaining flange 2 and the side panel 200 increases, the seal is tighter, and the sealing performance of the first water retaining flange 2 is ensured. When the second water retaining flange 3 is washed by rainwater, the overlap between the second water retaining flange 3 and the door panel 100 increases, and the sealing performance of the second water retaining flange 3 is ensured.

[0040] As for the interference between the first water retaining flange 2 and the second water retaining flange 3, due to the frequent opening and closing of the car door, the interference between the car door sheet metal and the second water retaining flange 3 is larger, ensuring that the second water retaining flange 3 can maintain a certain interference with the car door sheet metal when the car door is opened or closed.

[0041] A first water channel 4 is provided at the bottom of the first water retaining flange 2, and a second water channel 5 is provided at the bottom of the second water retaining flange 3. The bottom here refers to the side away from the door sheet metal 100. The provision of the first and second water channels 4 and 5 guides the flow of water in the first sealed area when it is high, facilitating its outflow without causing water accumulation within the first sealed area.

[0042] like Figure 1 and Figure 2As shown, to prevent failure of the first water-retaining flange 2, a third water-retaining flange 6 is provided on the side of the sealing strip body 1 near the door sheet metal 100. This flange extends from the bottom of the sealing strip body 1 toward the door sheet metal 100 and is connected to the door sheet metal 100. The bottom of the sealing strip body 1 here refers to the side of the sealing strip body 1 away from the door frame stop. This connection between the third water-retaining flange 6 and the door sheet metal 100 further enhances sealing, preventing rainwater and other substances from flowing along the inner side of the door sheet metal 100 and into the vehicle through the bottom of the sealing strip body 1.

[0043] The second and third water-retaining flanges 3 and 6 are spaced apart along the length of the door sheet metal 100 and form a second sealing area. If the second water-retaining flange 3 fails, rainwater will flow along the inside of the door sheet metal 100 and into the second sealing area, which will prevent water from entering the vehicle. The third water-retaining flange 6 creates a double seal on the inside of the door sheet metal 100, improving the sealing performance of the door gap sealing structure.

[0044] The interference amount between the third water retaining flange 6 and the door sheet metal 100 is 0.5-1 mm. For example, the interference amount between the third water retaining flange 6 and the door sheet metal 100 is 1 mm.

[0045] The bottom of the third water retaining flange 6 is provided with a third water guide groove 7. Here, by providing the third water guide groove 7, when the water flow in the second sealing area is large, it can play a guiding role, which is conducive to the water flow out of the second sealing area without forming a water accumulation area in the second sealing area.

[0046] The bottom of the sealing strip body 1 is connected to the door inner panel 102 of the vehicle door sheet metal 100 via a clip 8. A clipping cavity 9 is provided at the bottom of the sealing strip body 1, which engages with the clip 8. Connecting the sealing strip body to the door inner panel 102 via the clip 8 improves the reliability of the connection between the sealing strip body and the door inner panel 102. Specifically, one end of the clip 8 is positioned within the clipping cavity 9, while the other end is secured to the interior of the vehicle door. By providing the clipping cavity 9 at the bottom of the sealing strip body 1 and concealing one end of the clip 8 within the body 1, the space occupied by the clip 8 can be reduced.

[0047] Exemplarily, the clip 8 is a buckle.

[0048] The sealing strip body 1 is provided with weight-reducing holes, which reduce the weight while ensuring the functionality, and are conducive to achieving lightweighting of the vehicle. In addition, in this embodiment, weight-reducing holes are provided on the sealing strip body to form a bubble tube structure. The sealing strip body is made of EPDM material, which has better aging resistance.

[0049] At the same time, a weight-reducing hole is opened on the sealing strip body to form a bubble tube structure. The sealing strip body is made of EPDM material. When installing the fixing buckle, the clip 8 is first installed on the door inner panel 102, and then the sealing strip body is squeezed to make it elastically deformed and the sealing strip body is connected to the clip 8.

[0050] The bottom of the sealing strip body 1 here is provided with a connecting protrusion 10 connected to the door inner panel 102, which reduces the contact area between the sealing strip body and the door inner panel 102, improves the fit tightness between the sealing strip body and the door inner panel 102, thereby reducing the possibility of rainwater and the like flowing into the vehicle from the bottom of the sealing strip body, and improving the sealing performance of the sealing strip body.

[0051] Furthermore, the connecting protrusion 10 is located on both sides of the clip 8, and a storage space for accommodating part of the clip 8 is formed between the connecting protrusion 10 and the door inner panel 102, which reasonably optimizes the space layout and reduces the space occupied by the door gap sealing structure.

[0052] A second embodiment of the present invention provides a vehicle, comprising the above-mentioned vehicle door gap sealing structure.

[0053] like Figure 3 As shown, the vehicle further includes a door strip sealing structure 400 and a door frame strip sealing structure 500. The door gap sealing structure, the door strip sealing structure 400, and the door frame strip sealing structure 500 are arranged in sequence from the outside of the vehicle door to the inside of the vehicle door. Here, the outside of the vehicle door refers to the side facing the outside of the vehicle, and the inside of the vehicle door refers to the side facing the inside of the vehicle.

[0054] The door strip sealing structure 400 here is arranged between the door inner panel 102 and the side panel sheet metal 200, and the door frame strip sealing structure 500 here is arranged between the door inner panel 102 and the side panel sheet metal 200, forming a three-layer sealing structure between the door panel sheet metal 100 and the side panel sheet metal 200 to improve the sealing performance.
