Vehicle body false window structure and truck

Abstract

The invention discloses a vehicle body false window structure and a truck. The vehicle body false window structure comprises a false window plate (1) for covering a vehicle window (C), and an enclosure outer plate (2) and an enclosure inner plate (3) surrounding the vehicle window, wherein the false window plate comprises a center body part (11) and an outer periphery part (13); the outer periphery part is joined on the inner side wall of the enclosure inner plate; and the center body part is outwards projected from the internal of the vehicle window, so that a stop positioning structure is formed between the false window plate and the vehicle window. The false window plate dose not adopt a flat form anymore, but the stop positioning structure is formed between the false window plate and the vehicle window. The false window plate is mounted at the inner side; the center body part is outwards projected from the interior of the vehicle window; the stop positioning structure is clamped at the edge of the vehicle window; and the outer periphery part is welded on the inner wall surface of the enclosure inner plate. The stop positioning structure saves the labor force, is convenient for welding operation, and guarantees the welding consistency. The false window plate can preferably adopt a carbon dioxide arc welding mode to effectively prevent various surface quality problems caused by welding.

Description

technical field [0001] The invention relates to the field of vehicle structures, in particular to a blind window structure of a vehicle body. Background technique [0002] Clear glass windows are usually optional in vehicle types such as cargo vehicles. However, for the convenience of processing and assembling, the body structure does not usually change the design, and the blind window structure is generally formed by installing a cover plate on the vehicle window for this reason. [0003] like figure 1 As shown, in the prior art, the blind window panel 1 (that is, the cover panel) is usually sealed on the side wall outer panel 2 around the window C from the outside of the vehicle body. Since the outer contour of the blind window panel 1 needs to be larger than the outline of the window C, in the case of a larger area of ​​the window C, the blind window panel 1 has a larger size and weight, so that the blind window panel 1 is welded to the side wall It is not easy to supp...

AI Technical Summary

Problems solved by technology

However, whether it is spot welding or gas shielded welding, it is difficult to avoid defects such as weld penetration, pitting, outer plate distortion, etc.

As mentioned above, it is difficult to ensure the precision of tailor welding by making positioning tooling in the way of outer side panel, so that the consistency of body welding cannot be guaranteed

In addition, welding operators have high labor intensity, high operation complexity, and a large number of personnel involved in welding, which cannot guarantee production efficiency and increases production costs
