Problems solved by technology

[0004] 1. The size of the window frame is large due to the arrangement of the upper guide rail on the upper part of the door opening, which does not match the window frame of the front door. The joint between the sliding door and the side wall needs to go around the roof position, which destroys the integrity of the side wall and affects the side shape of the vehicle. ;
[0005] 2. The structure of the upper guide rail adopts a built-in structure. There will be a large space on the interior ceiling to hide the guide rail, and it will also affect the arrangement of the ceiling safety air curtain;
[0006] 3. Due to the relationship between the upper guide rail, the sliding door cannot be equipped with a complete set of secondary seals, which is not conducive to the improvement of the NVH performance of the vehicle

Abstract

The invention discloses an automobile sliding door system. The automobile sliding door system comprises a sliding door body, a middle guide rail and a lower guide rail, wherein a middle hinge matched with the middle guide rail is arranged in the middle of the sliding door body and a lower hinge matched with the lower guide rail is arranged at the lower part of the sliding door body; the lower guide rail comprises a lower guide rail upper transverse wall, a lower guide rail lower transverse wall and a lower guide rail vertical wall for connecting the lower guide rail upper transverse wall and the lower guide rail lower transverse wall; the lower guide rail further comprises a first vertical overturning edge which is connected with the lower guide rail upper transverse wall and a first guide groove which is formed by the first vertical overturning edge, the lower guide rail upper transverse wall and the lower guide rail vertical wall in a surrounding manner and has a downward opening; the lower hinge comprises a lower hinging part and a lower bearing part; the lower bearing part comprises a first bearing and a second bearing; the first bearing rolls along the lower guide rail vertical wall or the first vertical overturning edge by taking the vertical direction as the axial direction; the second bearing rolls along the upper surface of the lower guide rail lower transverse wall by taking the direction vertical to the lower guide rail vertical wall as the axial direction. According to the automobile sliding door system, an upper guide rail is not used under the condition of not influencing an original sliding function of the sliding door system, the integrity of a side wall structure is guaranteed and a good opening / closing performance is obtained.

Description

technical field [0001] The invention relates to the technical field of automobile design, in particular to an automobile and an electric sliding door system thereof. Background technique [0002] At present, the technical solutions of sliding doors used in traditional medium and large vehicles in China are mostly in the form of three guide rails. The upper guide rail and upper hinge provide ±Y-direction (perpendicular to the side door direction) freedom limit, the middle guide rail provides ±Y-direction freedom limit and auxiliary load-bearing, and the lower guide rail is responsible for the main load-bearing (limit +Z-direction freedom). The Y direction of the upper guide rail and the middle guide rail is always limited to the opposite direction, and the generated torque around the X direction (the moving direction of the side door) is used to offset the torsion during the opening process of the sliding door. [0003] The inventor of the present application found that the ...
