Integral rolling rain gutter side top covering part

Abstract

The invention discloses an integral rolling rain gutter side top covering part, which includes an integral rain gutter side top skin covering part body, a first rib line, a second rib line, a seam allowance flange and a rain gutter. The integral rain gutter side top skin covering part body, a vehicle roof frame assembly, side window glass, a side wall frame and a glass pasting caulking compound form a side wall closed structure. The integral rolling rain gutter side top covering part has the beneficial effects that through a scheme of replacing a self-tapping screw with an integral rolling rain gutter for fixing aluminum alloy rain gutter, rainwater is prevented from entering a vehicle roof frame through a fixing hole of the self-tapping screw, and the possibility of the vehicle roof framecorroded by the rainwater is decreased. According to the integral rolling rain gutter side top covering part, through the built-in first rib line and second rib line, integral internal stress of theintegral rain gutter side top skin covering part is enhanced, the ability resistant to thermal deformation of high-temperature electrophoretic fluid applied to side top skin during vehicle electrophoresis is improved, the vehicle appearance quality of the side top skin is improved, and then the purpose of improving the reliability of parts by adjusting the process and tools of the parts is achieved.

Description

technical field [0001] The invention relates to a cover, in particular to an integral rolling rain gutter side roof cover, which belongs to the technical field of application of the rain gutter side roof cover. Background technique [0002] At present, in the domestic bus market, in the welding process of the side roof skin of the roof, the single side roof skin welding mode is still used in the welding first, and then the side roof skin is welded in the final assembly after electrophoresis of the white leather body. Craft tooling pattern fixed by screws on the top aluminum alloy sink. In such a process, after electrophoresis of the white leather body, the side roof skin is prone to deformation after electrophoresis caused by uneven heating; the aluminum alloy water tank on the side roof is fixed by screws, leaving the hidden danger of water leakage at the screw fixing points. As more and more school bus products have been put on the market, the product functions are still ...

AI Technical Summary

Problems solved by technology

The side top skin of the integral rain gutter is formed by one-time rolling, which completely solves the hidden danger of water leakage at the fixing point of the self-tapping screws of the aluminum alloy water tank. The overall internal stress of the side roof skin cover can improve the ability of the side roof skin to resist heat deformation before and after vehicle electrophoresis, and the appearance quality of the side roof skin can improve the reliability of parts through the adjustment of parts process tooling. The performance purpose also increases the internal stress of the side roof skin of the vehicle accordingly, avoiding the agitation of the side roof skin caused by the uneven heating of the electrophoretic fluid after the white leather body is electrophoresed
