Description

Technical Field

[0001] The present application relates to the field of automobile bodies, and in particular to a rear triangular window frame structure of a vehicle body and a vehicle. Background Art

[0002] The vehicle's rear triangular window body structure involves the matching and installation of the rear door, roof trim, rear triangular window and other parts. At present, the installation structure of the rear triangular window on the body-in-white side is welded with two layers of side panel outer panel and side panel inner panel. A notch is opened at the installation point on the inner panel to avoid the buckle. The buckle is clamped on the side panel outer panel. The rear triangular window comes with sealant and is connected to the sheet metal hole through the buckle.
