AI Technical Summary

Technical Problem

In the existing technology, the limiting structure of the tailgate is difficult to adapt to the deformation of the door body caused by long-term use, resulting in inconsistent changes in the gap between the door body and the door frame, which affects the aesthetics and service life. At the same time, the fixed limiting structure is difficult to adapt to different vehicle models and manufacturing and assembly errors.

Method used

An adjustable rear door limiting structure is designed by setting a limiting block on the door body and a limiting seat on the door frame. The limiting block can be adjusted to adjust the gap between the door body and the door frame. The limiting block is provided with a through hole and an abutment surface, and is equipped with scale lines and positioning posts to achieve precise adjustment. The limiting seat adopts a lightweight design and embedded bracket to improve support performance.

Benefits of technology

It enables precise adjustment of the gap between the door body and the door frame, improves the problem of non-standard gaps caused by door deformation and assembly errors, increases the service life and closing effect of the back door, reduces abnormal noise, and enhances the user experience.

Abstract

The utility model relates to a vehicle body technical field and provide a back door limiting structure and vehicle, the utility model discloses a back door limiting structure includes the door frame, is located on the door body of door frame and limiting piece and limiting seat. Among them, limiting piece is located at the part opposite of door body edge and door frame, and limiting seat is located on the position corresponding with limiting piece of door frame, and with the closing of door body, limiting seat and limiting piece abutment cooperation;Limiting piece position adjustablely is fixed on the door body, and the position of limiting piece is adjusted, can change the gap size between the door body and door frame under the closed state. The utility model discloses a back door limiting structure, through adjusting the position of limiting piece on the door body, can adjust the gap between the door body and door frame to the scale range required by assembly quality, help to improve the situation that the back door assembly gap is not standard due to the factors such as door body deformation, component manufacturing or assembly error.
