Transmission mechanism of automobile panoramic sunroof, automobile sunroof assembly and vehicle

Technical Field

The utility model relates to an sunroof technical field especially relates to a drive mechanism and sunroof assembly and vehicle that is used for making up outer gliding style car panorama skylight down.

Background

Because the window visible width of the automobile panoramic sunroof is larger than that of a common sunroof, the automobile panoramic sunroof can be seen in a top view when a user sits in an automobile, and is popular among consumers. Most panoramic skylights are two pieces of independent front and back glass, and the front glass can move backwards and upwards relative to the back glass under the driving of a skylight transmission mechanism group so as to realize the opening and closing or other use states of the skylight.

At present, most of the existing skylight transmission mechanism sets mainly include a skylight guide rail, a glass panel support arm, a linkage lifting arm, a guide sliding block, a driving piece, a mechanism limiting piece, a sliding foot and the like, wherein a guide groove for raising and lifting skylight glass is formed on the guide sliding block, a pin shaft is arranged on the linkage lifting arm, the pin shaft is inserted into the guide groove, the guide sliding block moves on the skylight guide rail, so that the pin shaft slides in the guide groove, and the linkage lifting arm is driven to move in the vertical direction (Z direction) or the axial direction (X direction) of the skylight guide rail. The limitation of the linkage lifting arm in the width direction (Y direction) of the skylight guide rail is realized by the fact that the end part of the pin shaft is abutted against the bottom of the guide groove, and the end surface of the sliding foot or the guide protrusion on the other side (opposite to the other side of the pin shaft) of the linkage lifting arm is abutted against the side surface of the skylight guide rail, so that the limitation in the Y direction is realized. For example, chinese patent CN102910054A discloses a roof system of a vehicle, which adopts the technical scheme that the restriction in the Y direction is realized by the joint contact of the end surface of a pin shaft and the bottom of a guide groove and the end surface of a sliding foot and the end surface of a sunroof rail.
