Compared with the prior art, the vehicle door assembly provided by the embodiment has the advantages that the vehicle door sealing strip 200 is used for realizing the sealing fit between the conventional vehicle door assembly and the side wall sheet metal structure 400, the door seam sealing strip 300 of the embodiment is connected with the vehicle door sheet metal structure 100 through the upper base body 30a and the lower base body 30b, meanwhile, the abutting deformation between the two upper lip edges 30c is basically not influenced, the abutting deformation between the two lower lip edges 30d is basically not influenced, the two upper lip edges 30c and the two lower lip edges 30d can be effectively guaranteed to be in effective sealing abutting connection with the vehicle door sheet metal structure 100 or the side wall sheet metal structure 400 on the corresponding side, the sealing reliability of the door seam sealing strip 300 is guaranteed, and then, a double-pass seal is formed between the vehicle door and the side wall through the vehicle door sealing strip 200 and the door seam sealing strip 300; simultaneously through the position of reasonable setting crack sealing strip 300, make crack sealing strip 300 be close to the edge line of door sheet metal structure 100 as far as possible, can realize carrying out the function of shutoff to the crack of the peripheral formation of door sealing strip 200, one can avoid pollutants such as dust to bore into the crack, two still block the crack and the direct intercommunication of external space, avoid crack department to produce the problem of wind noise.

In some embodiments, the lower substrate 30b may have a structure as shown in fig. 5 to 7 and 10 to 13. Referring to fig. 5 to 7 and 10 to 13, the lower base 30b includes a lower main body 30b1 and an adapter 30b2 disposed on a side of the lower main body 30b1 facing the side gusset sheet metal structure 400, and the adapter 30b2 is a hollow structure. The lower body 30b1 is used for connection to the door panel structure 100. For the position with larger door seam width (generally, the door seam position corresponding to the middle lower part of the vehicle door), the lip with longer length needs to be arranged to be in contact with the vehicle door sheet metal structure 100 and the side wall sheet metal structure 400, but due to the limitation of the door seam size, the thickness of the lip is difficult to increase, on the premise of not increasing the thickness of the lip, the elastic deformation capability of the lip can be weakened due to the overlarge length of the lip, and the sealing performance of the lip is not favorably maintained, therefore, the hollow adapter 30b2 is arranged in the embodiment, even if the width of the adapter 30b2 is larger, the adapter has good elastic deformation capability, the adapter 30b2 is used as the arrangement base of the lower lip 30d, so that the adapter 30b2 adapts to the width of the corresponding position of the door seam (slightly smaller than the width of the corresponding position of the door seam), the distance between the two lower lips 30d can be larger, and on the premise that the lower lip 30d can still maintain the smaller width size, the lower lip 30d can also be effectively abutted against the vehicle door sheet metal structure 100 and the side wall sheet metal structure 400, and the sealing performance of the lower lip 30d is prevented from being influenced.

On the basis of the above embodiment, referring to fig. 5 to 7 and 10 to 13, in order to reduce the width of the lower lip 30d to the maximum extent and ensure that the lower lip 30d has high elastic deformation capability, the two lower lips 30d are respectively located at the inner edge and the outer edge of the adapter 30b 2.

In some embodiments, the above-mentioned aptamer 30b2 may adopt a structure as shown in fig. 6. Referring to fig. 6, the inner and outer widths of the lower body 30b1 are smaller than the inner and outer widths of the fitting body 30b2, and the inner and outer widths of the fitting body 30b2 are gradually increased in a direction toward the side wall sheet metal structure 400. In order to facilitate assembly, the width of the lower main body 30b1 is smaller, and the adapter 30b2 is set to be of a structure with gradually-changed inner and outer widths, so that the connection with the lower main body 30b1 can be met, and the width requirement of the corresponding door gap position can be met. In specific implementation, the lower body 30b1 and the adapter 30b2 are distributed along the front-back direction.

Some embodiments employ the structure shown in fig. 2-14. Referring to fig. 2 to 14, a sealing edge 30e is disposed on a side of the upper base 30a away from the side wall sheet metal structure 400 and a side of the lower main body 30b1 away from the side wall sheet metal structure 400. In specific implementation, the sealing edges 30e may be disposed at intervals, the sealing edges 30e are respectively located at two opposite sides of an assembly point, where the assembly point refers to a position where the upper base 30a and the lower main body 30b1 are connected to the vehicle door sheet metal structure 100, for example, a position where the fastening member 30j is located in the drawing is the assembly point. After the door sheet metal structure 100 is connected, the upper base body 30a and the lower main body 30b1 can generate certain elastic deformation under the influence of the assembly acting force, if the upper base body 30a and the lower main body 30b1 are in surface contact with the door sheet metal structure 100, the area outside the assembly point position can be warped to a certain degree, gaps are generated between the upper base body 30a and the lower main body 30b1 and the door sheet metal structure 100, on one hand, the sealing performance is influenced, and on the other hand, abnormal sound is easily generated in the vehicle driving process. In the embodiment, by arranging the sealing edge 30e, the contact area between the upper base body 30a and the lower main body 30b1 and the door sheet metal structure 100 is reduced, the tightness and reliability of the contact between the upper base body 30a and the lower main body 30b1 and the door sheet metal structure 100 are ensured, and the generation of abnormal sound can be avoided.

In order to achieve assembly with the door sheet metal structure 100, some embodiments employ a structure as shown in fig. 1, 8 to 13.
