As shown in
In the embodiment of the subject application, by adding a second sealing part 12 for filling the gap space between the glass piece 2 and the cover plate 3 on a side of the sealing strip body 1 facing the glass piece 2, compared to the prior art, the first sealing part 11 and the second sealing part 12 in the structure form two defensive lines for sealing and water-blocking, ensuring that even if the added second sealing part 12 fails, the first sealing part 11 will still serve as the second defensive line, thus provide better sealing and waterproofing function, ensuring that even when the amount of water is large, water will not easily enter into the vehicle through the glass piece 2 to form water leakage. At the same time, the gap space between the glass piece 2 and the cover plate 3 is filled through the second sealing part 12, which can effectively reduce the amount of water entering between the glass piece 2 and the cover plate 3, thereby effectively avoiding the excessive water amount that causes water to cross the glass piece 2 and enter into the vehicle and form water leakage.
As shown in
Considering that when the rain is heavy, water may enter into the gap between the glass piece 2 and the sealing strip body 1 through a position where the second sealing part 12 and the glass piece 2 abuts against and attaches to each other, and accumulate, causing water leakage in the vehicle; in some embodiments of the subject application, the portion of the sealing strip body 1 between the third sealing part 13 and the second sealing part 12 is configured as a first arc segment 14, and the second sealing part 12, the first arc segment 14 and the third sealing part 13 form a first water guide groove 15; by setting a portion of the sealing strip body 1 located between the third sealing part 13 and the second sealing part 12 as an arc segment to further expand the space of the first water guide groove 15, which not only facilitates the discharge of water that enters the first water guide groove 15 through a position where the second sealing part 12 and the glass piece 2 abuts against and attaches to each other, but also increasing the accumulation capacity of water entering through the position where the second sealing part 12 and the glass piece 2 abuts against and attaches to each other, and can more effectively prevent water from passing through the second defensive line formed by the third sealing part 13, and can play a better sealing and waterproof role.
Considering that the amount of water entering the first water guide groove 15 through a position where the second sealing part 12 and the glass piece 2 abuts against and attaches to each other is so large that the first water guide groove 15 cannot be discharged in time, water may enter into the gap between the glass piece 2 and a portion of the sealing strip body 1 between the first sealing part 11 and the second sealing part 13 through a position where the third sealing part 13 and the glass piece 2 abuts against and attaches to each other, and accumulate, causing water leakage in the vehicle; in some embodiments of the subject application, the portion of the sealing strip body 1 between the first sealing part 11 and the third sealing part 13 is configured as a second arc segment 16, and the first sealing part 11, the second arc segment 16 and the third sealing part 13 form a second water guide groove 17; by setting a portion of the sealing strip body 1 located between the first sealing part 11 and the third sealing part 13 as an arc segment to further expand the space of the second water guide groove 17, which not only facilitates the discharge of water that enters the second water guide groove 17 through the position where the third sealing part 13 and the glass piece 2 abuts against and attaches to each other, but also increasing the accumulation capacity of water entering through the position where the third sealing part 13 and the glass piece 2 abuts against and attaches to each other, and can more effectively prevent water from passing through the third defensive line formed by the first sealing part 11, and can play a better sealing and waterproof role.
In some embodiments of the subject application, the third sealing part 13 is configured as a third sealing lip distributed in a trend of gradually away from the center of the circle in the circumferential direction. The third sealing part 13 arranged in such a shape can further increase the area of abutting against and attaching with the glass piece 2, and can more effectively prevent water flow from passing through the defensive line formed by the third sealing part 13, and can play a better sealing and waterproof role. It should be noted that the trend distribution of gradually away from the center of the circle in the circumferential direction described in this embodiment is based on the perspective shown in
In some embodiments of the subject application, the second sealing part 12 includes an arc surface 121 distributed in a trend of gradually approaching the center of the circle in the circumferential direction. The arc surface 121 abuts against and is attached to the side, facing the cover plate 3, of the glass piece 2. The arc surface 121 further increases the area abutting against and attaching to the side, facing the cover plate 3, of the glass piece 2, which can more effectively prevent water flow from passing through the defensive line formed by the second sealing part 12, and achieve better sealing and waterproofing effect. It should be noted that the trend distribution of gradually approaching the center of the circle in the circumferential direction described in this embodiment is based on the perspective shown in
