Assembly-welding type automobile rear wall window frame

Abstract

The invention discloses an assembly-welding type automobile rear wall window frame which is characterized by comprising a left-side wall welding assembly, a top cover welding assembly, a right-side wall welding assembly and a rear wall welding assembly that are assembled and welded to form a trapezoidal window frame, wherein the trapezoidal window frame comprises four parts, i.e. a left half part, an upper half part, a right half part and a lower half part. By virtue of the assembly-welding type automobile rear wall window frame, the restriction by a rear wall panel is broken, the area outside the rear wall panel is developed, thus the rear wall window frame is enlarged, the back view is expanded, and the driving safety is improved. By adopting an assembly-welding type rear wall window frame structure, a traditional mini-truck body-in-white assembly process and the structures of parts such as the traditional top cover, the rear wall panel and the like are changed. The rear part of thetop cover is in a circular arc surface structure, a visual welding flanging at the rear of the traditional top cover is removed, and thus the attractiveness of an automobile is increased. Moreover, the manufacturing difficulty is reduced because the rear wall panel is changed to an L shape from a box shape.

Description

technical field [0001] The invention relates to automobile body parts, in particular to an automobile assembled and welded rear wall window frame. Background technique [0002] At present, the rear wall window frame of the minivan is a boss part on the rear wall, which is a rectangle with rounded corners at four corners and is located on the top of the rear wall.
