[0005] Wherein, both ends of the hinge arm are respectively connected to the four-link hinge base and the vehicle body side sliding rail through bolts.
[0006] Wherein, the four-link hinge base is welded to the vehicle body.
[0007] Wherein, the sliding door hinge is installed on the door through bolts.
[0008] Wherein, both the door side sliding rail and the vehicle body side sliding rail have a U-shaped groove structure.
[0009] Compared with the prior art, the four-link mechanism device for a sliding door of the utility model has the following beneficial effects:
[0010] The four-link mechanism device for a sliding door of the utility model can effectively cancel the middle sliding rail of the conventional sliding door, improve the aesthetic appearance of the sliding door, and increase the space for second-row passengers. It reduces the intrusion amount of the lower sliding rail in the Y direction into the vehicle body, and is convenient for the vehicle body to achieve common platforms for different vehicle models.
