[0020] Example 1

[0021] like Figure 2-6 As shown, the double slide rail assembly structure of the sliding door of this embodiment includes a sliding door body 1, a side panel 2, an upper slide rail 3, an upper hinge 4, an upper slide rail double guide roller 5, an upper slide rail bearing roller 6, a door side slide rail 8, a body side slide rail 7, a door side roller 9, a body side roller 10, a lower hinge 11, a hinge arm 14 and a four-link hinge seat 15. In this embodiment, the middle slide rail of the existing sliding door is eliminated, and the lower slide rail of the existing sliding door is changed into a double slide rail assembly 13 and a four-link mechanism 12. The double slide rails are the door side slide rail 8 and the body side slide rail 7, and two sets of roller supports are added, namely the door side roller 9 and the body side roller 10, to ensure that the sliding door forms a triangular stable support; due to the elimination of the middle slide rail, the upper slide rail is adjusted from a single guide wheel to an upper slide rail double guide roller 5 and an upper slide rail bearing roller 6 to bear the weight of the door; a four-link mechanism is added to the lower hinge to stabilize the door.

[0022] Specifically, in this embodiment, the upper slide rail 3 is arranged on the side wall 2, and the upper slide rail double guide roller 5 and the upper slide rail bearing roller 6 are installed on the upper slide rail 3, one end of the upper hinge 4 is connected to the upper slide rail double guide roller 5 and the upper slide rail bearing roller 6, and the other end of the upper hinge 4 is installed on the sliding door body 1.

[0023] The upper slide rail 3, the upper hinge 4, the upper slide rail double guide rollers 5, and the upper slide rail bearing rollers 6 constitute an upper slide rail assembly, which is installed on the vehicle door through the upper hinge 4 and works together to control the translation of the upper part of the vehicle door in the Y direction.

[0024] The door side slide rail 8, the body side slide rail 7, the door side roller 9, the body side roller 10, the lower hinge 11, the hinge arm 14 and the four-link hinge seat 15 constitute a double slide rail assembly 13. The four-link hinge seat 15 is installed on the body by bolts, the door side slide rail 8 and the four-link hinge seat 15 are movably connected through two hinge arms 14, and the hinge arms 14 are respectively connected to the door side slide rail 8 and the four-link hinge seat 15 by bolts.

[0025] The body side roller 10 is mounted on the body side lower rail 7, and the body side roller 10 is connected to one end of the lower hinge 11, and the other end of the lower hinge 11 is mounted on the sliding door body 1 through a bolt. One end of the door side roller 9 is mounted on the door side lower rail 8, and the other end is mounted on the body side lower rail 7 through a bracket 16.

[0026] In this embodiment, the double slide rail assembly controls the constraints of the door in the Y and Z directions, and acts together with the upper slide rail assembly on the door to ensure that the sliding door has only the degree of freedom in the X direction when moving, thereby realizing the opening of the sliding door.
