Mounting structure of upper guide rail of automobile sliding door

Abstract

The invention discloses a mounting structure of an upper guide rail of an automobile sliding door. The mounting structure comprises a first connecting plate and a second connecting plate, the left side and the right side of the first connecting plate are connected with a side wall outer plate, a cavity is formed between the outer wall of the first connecting plate and the side wall outer plate, the upper side of the second connecting plate is connected with the inner wall of the first connecting plate, and the lower portion of the second connecting plate is bent towards the outer side of a vehicle body to form a drainage plate; an open box body is formed between the outer wall of the second connecting plate and the first connecting plate, and an opening of the box body faces the outside ofthe vehicle body; the top face of the upper guide rail is fixedly connected with the middle of the inner wall of the first connecting plate, and the upper guide rail is located in the open box body.The sliding door upper guide rail assembly can reduce the assembling difficulty of the sliding door upper guide rail, improve the assembling precision of the sliding door upper guide rail assembly, guarantee the gap surface difference between a vehicle door and a side wall outer plate, improve the corrosion resistance of the sliding door upper guide rail and improve the influence of the sliding door upper guide rail arranged on the outer side of the side wall outer plate on the appearance. The invention further discloses an automobile with the mounting structure of the upper guide rail of theautomobile sliding door.

Description

technical field [0001] The invention relates to the installation of automobile parts, in particular to an installation structure of a guide rail on an automobile sliding door and an automobile. Background technique [0002] At present, the guide rail structure of most automobile sliding doors adopts the connection structure between the guide rail and the reinforcement, see figure 1 , the existing upper guide rail 100 forms a guide rail assembly with the first connecting bracket 101 and the second connecting bracket 102, and the first connecting bracket 101 and the second connecting bracket 102 are respectively located at the rear end and the front end of the existing upper guide rail 100. The upper reinforcement 108 of the middle door and window frame, the guide rail reinforcement ring 105, the upper reinforcement 106 and the lower reinforcement 107 form the upper reinforcement assembly of the middle door and window frame. After the guide rail assembly is welded on the outs...

AI Technical Summary

Problems solved by technology

After the guide rail assembly is welded on the outside of the side wall outer panel 3, the upper reinforcement assembly of the middle door and window frame is welded on the inner side of the side wall outer panel 3. The guide rail 100 is correspondingly matched, and after welding is completed, it is welded together with the B-pillar reinforcement 104 and the C-pillar reinforcement 103 to form a guide rail welding structure. This kind of guide rail welding structure needs to be divided into multiple assemblies before combined welding. Secondary positioning affects the accuracy and consistency of the guide rail, thereby affecting the gap between the door and the side wall

In addition, after the sliding door is opened, the guide rail assembly is located outside the side wall outer panel, which is not conducive to the anti-corrosion maintenance of the guide rail, and has adverse effects on the appearance and use.
