Specifically, in the present embodiment, the overlapping structure 75 includes a first overlapping edge 751 and a second overlapping edge 752 disposed at the front end of the water retaining lip 72, wherein the first overlapping edge 751 is used for overlapping with the water retaining lip 72 of the first upper corner 11 to ensure the sealing effect; the second overlapping edge 752 is located at the overlapping position of the first overlapping edge 751 and the water retaining lip 72 of the first upper corner 11 and is abutted against the door frame 6, so that water penetrating between the first overlapping edge 751 and the water retaining lip 72 of the first upper corner 11 can be led out of a sealing element, and the water drainage effect is further ensured.

In the above embodiment, the second connecting corner 21 further includes the drain portion 76, the drain portion 76 is disposed at the front end of the bubble tube 71 of the second connecting corner 21, the drain portion 76 is provided with the drain groove 761 and the drain hole 762 facing the vehicle exterior side, and in particular, the drain groove 761 is disposed at a position corresponding to the overlapping structure 75, as shown in fig. 11 and 12, the drain groove 761 is disposed so that, when water enters the vehicle door along the overlapping structure 75, the entered water is guided to the drain hole 762 and discharged to the outside of the seal along the drain hole 762, thereby further ensuring the sealing performance of the vehicle door seal.

Furthermore, in this embodiment, the drainage portion 76 further includes a drainage bowl 763, a side wall of the drainage bowl 763 is used for abutting against the doorframe seal 3 provided on the doorframe 6, i.e., the second upper corner 21 is used for providing a sealing surface for the doorframe seal 3 to ensure the sealing performance of the doorframe seal 3. And drainage bowl 763 is used for guaranteeing to discharge the water that gets into along the overlap joint between second upper corner 21 and the door frame sealing member 3, and is concrete, and the sealed section 23 of the straight line of back door 5 still is equipped with the sealed tube of tubular structure, and drainage bowl 763's bottom and this sealed tube intercommunication, and the water that drainage bowl 763 collected can get into in this sealed tube along its bottom to drop to the bottom and discharge, and is concrete, can be that the bottom of sealed tube is equipped with the apopore, also can be that second lower corner 22 is equipped with above-mentioned apopore.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
