Embodiment Construction

[0024] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] Figure 1-Figure 3 Some embodiments according to the invention are shown.

[0026] Such as figure 1 As shown, a side wall skin structure of a passenger car body includes a side wall frame and a side wall skin. The side wall frame is formed by welding an upper beam 7, a lower beam 6, and several diagonal braces 8, wherein the upper beam 7 , The lower crossbeam 6 is arranged horizontally and parallel to each other, and the diagonal braces 8 are arranged obliquely and connected between the lower crossbeam 6 and the upper crossbeam 7, wherein the outer surfaces of the upper crossbeam 7, the lower crossbeam 6 and some diagonal braces 8 are coplanar, as Subsequent welding of the side skin p...

Abstract

The invention discloses a passenger car body side skin structure and a skin process. The passenger car body side skin structure is characterized in that a side frame comprises an upper cross beam, a lower cross beam and a plurality of inclined supports, expansion materials are arranged on the outer side walls of the inclined supports, the side skin comprises a skin main body, an upper spigot and a lower spigot, the upper spigot is connected with the step surface of the upper cross beam, and the lower spigot is connected with the outer side wall of the lower cross beam. According to the car body side skin structure and the skin process, an edge folding mechanism on a side skin can improve the strength of the end surface of the side skin, a fault-tolerant gap is formed after the side skin and a cross beam are welded so that the influence of splashing and deformation caused by unevenness of the cross beam and welding on the flatness of the skin can be reduced, in addition, the filling materials are arranged on the inclined supports so that the flatness of the appearance of the side skin of a passenger car can be improved, and the attractiveness of the appearance can be improved to meet the requirements of the current market.

Description

technical field [0001] The invention relates to the field of automobile and passenger car skin production process, in particular to a passenger car body side wall skin structure and skin technology. Background technique [0002] With the rapid development of my country's economy, my country's bus manufacturing industry has made great progress, and the quality of customers' buses has gradually shifted from satisfying the basic performance of use to more comfortable and beautiful appearance. Among them, the skin of the bus body is one of the appearance products of the bus, and its smoothness directly affects the overall aesthetics of the bus. Therefore, in the design and production process of the body skin, it needs to be improved to improve the smoothness of the skin . [0003] Among them, the passenger car skin in the prior art generally uses pure plane skin, the upper and lower seams of the skin are flat, and there is no gap between the skin and the beam after welding, and...
