AI Technical Summary

Technical Problem

In the prior art, the sliding door support structure has reduced design freedom due to the configuration of a straight upper sliding track, and the lower sliding track affects the mounting of parts in the lower part of the vehicle body, while also making it difficult to effectively withstand the downward force of the door.

Method used

The system employs a first sliding support mechanism and a second sliding support mechanism, with first and second sliding tracks respectively positioned above and below the door opening. These tracks bear the weight of the door and the downward force, and limit the opening and closing trajectory of the door, thus eliminating the need for traditional upper or lower sliding tracks.

Benefits of technology

It increases the design freedom around the door opening and the component mounting capacity of the lower part of the vehicle body, effectively withstands the downward force of the door, and ensures the stable opening and closing of the door.

Abstract

In a sliding door support structure, the force in the downward direction of the door can be properly borne, and either the upper or lower sliding track can be discarded. A sliding door support structure is disclosed, comprising: a first sliding support mechanism having a first sliding track above and below the door opening in the vehicle body, which supports the door relative to the vehicle body and restricts the door's opening and closing trajectory by means of the first sliding track; and a second sliding support mechanism having second and third sliding tracks located below the upper end and above the lower end of the door opening in the vehicle body, supporting the door and restricting its opening and closing trajectory. The second and third sliding tracks are arranged separately in the vertical direction. The second sliding support mechanism bears the weight of the door and restricts its opening and closing trajectory by means of the second sliding track, and also bears the force in the downward direction of the door by means of the second and third sliding tracks.
