[0030] Example 1
[0031] like Figure 1-9As shown, the lower seal 25 of the B-pillar-free door of this embodiment includes a vertical structural part, which is composed of a first structural surface 1 and a second structural surface 5, and the first structural surface 1 and the second structural surface 5 are arranged vertically adjacent. The side end of the first structural surface 1 is provided with a bubble-shaped profile 2, which conforms to the compression characteristics and forms a certain interference amount with the front door sheet metal to meet the sealing requirements. The upper end of the bubble-shaped profile 2 is connected to the rear door sealing strip. The lower end of the vertical structural part is provided with an avoidance opening, and the necessary opening can be used to install the rear door hinge, buffer block, body sheet metal, etc. The vertical structural part is provided with a sealing member outer surface 6, and the sealing member outer surface 6 is overlapped with the front and rear doors to form a smooth sealing surface, providing a sealing surface for the side door opening sealing strip. A support end 7 is provided below the sealing member outer surface 6, and a first sealing surface 8 of the door sheet metal is provided below the support end 7, and a second sealing surface 11 of the door sheet metal is provided on the side of the bubble-shaped profile 2. The side of the bubble-shaped profile 2 is also provided with a first sealing surface 9 of the rear door sheet metal and a second sealing surface 10 of the rear door sheet metal. The inner surface of the vertical structural part is provided with a first supporting structure 12 and a second supporting structure 13, wherein the first supporting structure 12 is a three-dimensional trapezoidal structure and the second supporting structure 13 is a sloped supporting structure. The first supporting structure 12 and the second supporting structure 13 are provided with crisscrossing supporting ribs. The inner surface of the sealing part outer surface 6 and the supporting end 7 is provided with an inlay frame 14. The upper end of the vertical structural part is provided with 3M glue 16. A plurality of mounting points 15 are also provided on the lower seal of the B-pillar-free door.
[0032] The open-mouth design and bubble tube structure adopted in this embodiment help to form a close contact between the seal and the door sheet metal, thereby improving the sealing performance, preventing moisture, dust and other impurities from entering the interior of the door, and improving the sealing performance; using 3M tape to stick the upper edge can improve the durability of the seal, because 3M tape usually has high bonding strength and environmental resistance, ensuring that the seal will not fall off or shift during vehicle operation, especially in high temperature and vibration environments, thereby enhancing durability; the three-dimensional trapezoidal and sloped support structures and the criss-crossing support ribs can enhance the structural stability of the seal, so that it can better adapt to the opening and closing of the door and temperature changes, thereby improving structural stability; by inlaying a steel plate skeleton at the key position of the seal, the supporting strength of the seal can be significantly improved, thereby improving the structural integrity and durability of the entire door, and enhancing the supporting strength; and the use of the lower seal of the B-pillar-free door of this embodiment omits the seal at the corner position of the front door under the seam, saving costs.
