[0037] a glass slide rail 2, the glass slide rail 2 is in a long strip structure, the outer side wall of the glass slide rail 2 is respectively provided with a fixed part 21, an elastic compensation part 22 and a guide support part 23, the fixed part 21 is fixed to the inner side wall of the vehicle door glass 1;

[0038] The glass guide groove 3 is fixed on the door body and wraps the outer side of the glass slide rail 2, and is used to guide the movement of the glass slide rail 2. The elastic compensation part 22 and the guide support part 23 are respectively in sliding contact with the inner side wall of the glass guide groove 3. The elastic compensation part 22 is used to compensate the assembly gap between the glass guide groove 3 and the glass slide rail 2, so as to ensure the stability of the door glass under static and lifting dynamic conditions.

[0039] The glass guide groove 3 is an open groove of a U-shaped structure, which is an important part for ensuring the normal lifting of the door glass 1 and plays a sealing role.

[0040] The glass guide groove 3 is provided with a glass supporting and abutting lip 31 in contact with the inner side wall of the door glass 1, an end side sealing lip 32 in sliding connection with the dynamic sealing of the end side of the door glass 1, and a slide rail sealing lip 33 in sliding connection with the dynamic sealing of the glass slide rail 2.
