A buckle structure for fixing an integrated guide groove

Abstract

The invention discloses a buckle structure for fixing an integrated guide groove, which belongs to the field of automobile body accessories. The buckle structure at least includes: a wedge-shaped guide head, engaging legs, a cylindrical plug, a base, and a supporting rib. Through the wedge-shaped guide head set on the buckle, the buckle positioning hole of the side door sheet metal can be quickly identified, which is convenient for quickly and accurately fixing the positioning buckle of the corner window in the state of blind installation, and improves the convenience of the integrated guide groove assembly. The installation time is shortened, and the assembly efficiency is improved. The two raised reinforcing ribs are attached to the square window glass, which is similar to point contact, and the positioning of the buckle is relatively accurate, which reduces the shaking caused by poor profile matching and reduces the difficulty of assembly. Secure the channel to the side door by wedge-engaging the legs. The angle set by the end of the engaging leg is 30-45°, and the chamfer width is about 1mm, which facilitates the removal of the glass run channel for after-sales maintenance and saves rework time.

Description

Technical field [0001] The invention relates to the field of automobile body accessories, in particular to a buckle structure for fixing an integrated guide groove. Background technique [0002] With the rapid development of the automobile industry and the increase in demand for automobiles, the market has put forward higher requirements for the mass production method of automobile assembly line assembly. How to shorten and reduce the assembly time and process of parts and components has become the issue of the automobile industry. The key to improving assembly line assembly efficiency. [0003] The rear door guide groove is mainly used to seal the glass and the door of the vehicle. Generally, a four-corner fixed glass is added to the rear door so that the rear door glass can be lowered to the depth required by the design. The existing four-corner window is installed on the side door of the glass guide groove generally has two structural forms: one is the design of the rear door g...

AI Technical Summary

Problems solved by technology

[0005] Adopting the first segmented structure, there is a problem of overlap between the rear door guide groove and the four-corner window guide groove, which is prone to poor matching and affects the performance

Adopting the second type of integrated guide groove structure, it is necessary to add buckles to locate the corner window. Although the appearance matching and performance are greatly improved, when installing, the positioning buckles are blocked by the rear door guide groove and the black edge of the glass. , so the corner window buckle needs to be installed blindly, and it is difficult to find the positioning mounting hole of the body sheet metal during the operation, which brings a lot of inconvenience to the assembly, takes a long time, and the work efficiency is not high

[0006] Since the corner windows are all double-curved glass, and the existing base structure is that the entire plane is directly in contact with the surface of the square window glass, it is difficult to ensure the buckle base surface in consideration of glass tolerances, guide groove tolerances and sheet metal tolerances. It is fully matched with the hyperboloid of the glass, resulting in shaking back during snap-fit ​​assembly, which increases the difficulty of assembly

Moreover, the existing buckles are all cylindrical ends, and the gap between the positioning buckle plug and the mounting hole is only 0.5mm. It is difficult to quickly identify the buckle mounting hole on the sheet metal, and the work efficiency is low.
