Thus, the defect of sharp transition, namely sharp curvature change, can be avoided by amplifying the arc radius value of the corner structure J, so that the possibility of collapse of the corner structure J position of the rear glass sealing bubble tube 6 can be reduced.

Certainly, matching with the increase of the arc radius of the corner connecting structure J, the arc radius of the arc sealing edge m on the convex structure 501 is also larger, so that reliable abutting between the two sealing structures can be ensured, and the sealing effect is further ensured.

In this embodiment, referring to fig. 10 and 8, the compression amount of each convex structure 501 and the corresponding corner connecting structure J in the abutting fit is the same as the compression amount of the front glass edge-covering rubber strip 5 and the rear glass sealing bubble tube 6 in other abutting positions. Therefore, the sealing performance between the convex structure 501 and the corner connecting structure J can be ensured to be the same as that of other positions between the front glass edge-wrapping rubber strip 5 and the rear glass sealing bubble tube 6, and the integral sealing effect can be further ensured.

In addition, in order to avoid the fatigue permanent deformation at the corner connecting structure J of the rear glass sealing bubble tube 6 caused by the repeated opening and closing of the front glass 2, a sponge tube 7 is further arranged in the rear glass sealing bubble tube 6 at the position of the corner connecting structure J in a penetrating manner. The sponge tube 7 is arc-shaped along with the arrangement of the corner connecting structure J, and the length of the sponge tube can cover the arc length range of the whole corner connecting structure J.
