The invention discloses a bearing synchronizing mechanism of a wire-controlled automatic vehicle door, which comprises a left shifting fork 1, a left shifting rod 2, a left support 3, a bearing 4, a left connecting plate 5, a synchronizing rod 6, a guide rod 7, a guide rail 9, a right sliding barrel 10, a left sliding barrel 11, an optical axis 12, a right connecting plate 13, a right support 14, a right shifting rod 15, a right shifting fork 16, a left door panel 17 and a right door panel 18.

The left shifting fork 1 is fixed at the left end of the synchronizing rod 6, and drives the left shifting lever 2 and the left connecting plate 5 to move along with the rotation of the synchronizing rod 6. The left shift lever 2 is arranged on the left connecting plate 5 and can slide in a groove of the left shift fork 1. The left support 3 provides support for the synchronization rod 6 and the carrier bearing 4. Inner rings of the bearing bearings 4 are arranged at two ends of the optical axis 12, and outer rings are contacted with the left support 3 and the right support 14 and can move in the y direction of the left support 3 and the right support 14. The left connecting plate 5 provides a mounting position for the left shift lever 2, is connected with the optical axis 12, and can move along the y direction along with the bearing 4. The synchronizing bar 6 is mounted between the left support 3 and the right support 14 to be axially rotatable. One end of the guide rod 7 is fixed on the right sliding barrel 10, and the other end is provided with a guide bearing 8 which can move along the x direction along with the right sliding barrel 10. The guide bearing 8 is mounted on the guide bar 7 to be movable along the guide rail 9. The guide rail 9 provides directional guidance for the guide bearing 8. The right sliding cylinder 10 is connected with a right door plate 18, a guide rod 7 is fixed on the outer ring, and the inner ring is attached to the outer ring of the optical axis 12 and can move axially along the optical axis 12. The left sliding cylinder 11 is connected with the left door plate 17, and the inner ring is attached to the outer ring of the optical axis 12 and can move axially along the optical axis 12. Two ends of the optical axis 12 are respectively fixed with the left connecting plate 5 and the right connecting plate 13, and the outer ring is coated with the right sliding barrel 10 and the left sliding barrel 11. The right connecting plate 13 provides a mounting position for the right shift lever 15, connects the two optical axes 12, and can move along the y direction along with the bearing 4. The right support 14 provides support for the synchronization rod 6 and the carrier bearing 4. The right shift lever 15 is mounted on the right link plate 13 to be slidable in a groove of the right shift fork 16. The right shifting fork 16 is fixed at the right end of the synchronizing rod 6, and drives the synchronizing rod 6 to rotate along with the movement of the right connecting plate 13 and the right shifting rod 15. The left door plate 17 is mounted on the left slide 11, and the right door plate 18 is mounted on the right slide 10.

The working principle of the load-bearing synchronizing mechanism of the wire-controlled automatic vehicle door is as follows:

in the action process of the door, the left sliding cylinder 11 and the right sliding cylinder 10 respectively move leftwards and rightwards at the same speed along the x direction, the right sliding cylinder 10 drives the guide rod 7 to move rightwards, the guide bearing 8 on the fixed guide rod 7 is limited by the guide rail and moves forwards along the y direction except the right direction, and the guide bearing 8 drives the guide rod 7, the right sliding cylinder 10, the optical axis 12, the right connecting plate 13, the right deflector rod 15 and the bearing 4 to move forwards along the y direction; meanwhile, in the process of moving forward along the y direction, the right shift lever 15 on the right connecting plate 13 drives the right shift fork 16 to rotate, the right shift fork 16 drives the left shift fork 1 to rotate through the synchronizing rod 6, and the left shift fork 1 drives the left shift lever 2 and the left connecting plate 5 to move forward along the y direction through the bearing 4; the left slide cylinder 11 moves forward along the y direction through the optical axis 12, the left connecting plate 5 and the right connecting plate 13. At this time, the displacement of the left connecting plate 5 and the displacement of the right connecting plate 13 moving along the y direction are consistent, and the displacement of the left sliding tube 11 and the left door plate 117 moving along the y direction is consistent with the displacement of the right sliding tube 10 and the right door plate 18 moving along the y direction.
