As shown in FIG. 14 , the lower end of the middle column 22 is disposed opposite to the upper surface gap of the underframe side beam 30 , that is to say, the middle column 22 is not in direct contact with the underframe side beam 30 , as marked in FIG. 14 . The gap between the lower end of the middle column 22 and the upper surface of the underframe side beam 30 is a, as shown in FIG. 30 , that is, the middle column 22 and the side beam 30 of the underframe are connected by the connecting piece 80 . In this embodiment, the middle column 22 is not in contact with the side beam 30 of the chassis, and is connected by the connecting member 80, which solves the problem that the gap between the side wall column (the middle column 22) and the side beam 30 of the chassis is inconsistent in the past, and the gap between some positions is large and cannot be welded. technical issues.

According to a specific embodiment of the present invention, as shown in FIG. 15 to FIG. 17 , the connecting member 80 includes a first vertical rib 81 and a first vertical rib 81 that is bent to the same side along two vertical sides of the first vertical rib 81 . The two vertical ribs 82 form a similar C shape.

Specifically, the first vertical rib 81 and a pair of the second vertical ribs 82 form a groove, the size and shape of the groove match the outer surface of the middle column 22, and the groove is clamped in the middle After the upright post 22 is mounted, the inner sidewall of the groove is in contact with the outer surface of the middle upright post 22, so that the three surfaces of the connector 80 can be fitted and connected with the central upright post 22, and the structural strength is high; the first vertical rib 81 and a At least one of the second vertical ribs 82 is connected to the middle column 22 by welding, in other words, only the first vertical ribs 81 and the middle column 22 can be welded, or the first vertical ribs 81 and one of the The two vertical ribs 82 are welded to the central column 22 , the two second vertical ribs 82 can also be welded to the central column 22 , or the first vertical ribs 81 and the two second vertical ribs 82 can be welded to the central column 22 . Of course, for the reliability of the connection, in this embodiment, the first vertical rib 81 and the two second vertical ribs 82 are preferably welded to the central column 22 .

Further, the bottom ends of the first vertical rib 81 and a pair of the second vertical ribs 82 abut on and are welded on the bottom frame side beam 30 .

In order to facilitate welding, according to an embodiment of the present invention, openings 83 are formed on the surfaces of the first vertical rib 81 and a pair of the second vertical ribs 82, and the first vertical rib 81 and a pair of the The second vertical ribs 82 are welded to the central column 22 through the respective openings 83 . By adopting this form of welding, the vertical surface of the connector 80 can be connected more closely with the vertical surface of the middle column 22, and the structural strength can also be improved to a certain extent.

In one embodiment, the opening 83 may be an oblong hole, and the length direction of the oblong hole is along the vertical direction of the first vertical rib 81 and the second vertical rib 82 .

According to an embodiment of the present invention, a pair of vertical outer edges of the second vertical ribs 82 are respectively provided with notches 84, the surfaces of the notches 84 are inwardly concave arc surfaces, and the notches 84 and the second vertical The connection of the ribs 82 is an arc surface transition connection; reducing stress concentration.

In addition, in the current stainless steel car body manufacturing process, due to the need for upward deflection of the car body, the chassis will be prefabricated with the corresponding deflection as a whole, and the prefabrication of the overall deflection of the side wall is generally achieved by unit placement and door size adjustment. The wall element can only be prefabricated with small deflection or no deflection due to the influence of long side beams and inconsistent deflection change requirements, making it difficult for the side wall to achieve a curve change consistent with the deflection of the chassis. During the assembly process of the side wall and the chassis, due to the inability to fully match the deflection, the body of the lower side beam and the side beam of the chassis are poorly fitted, unable to meet the welding requirements, and it is difficult to adjust the height and size, and the assembly workload is large. In order to solve this problem, the embodiment of the present invention adopts the following technical solutions:

This embodiment also includes a side wall sill 10 installed between every two adjacent uprights 20, that is to say, a side wall sill 10 is installed between every two uprights 20, and all side wall sills 10 forms the main body of the lower side rail body 12 . The main body of the lower side beam body 12 adopts a segmented structure, which is more flexible and convenient for side wall assembly and deflection prefabrication.

The inclined plate 14 formed by slanting and bending on the side where 11 is located, and the horizontal plate 15 formed by extending horizontally from the end of the inclined plate 14; That is to say, after the rocker body 12 is installed, the horizontal plate 15 of the rocker body 12 abuts on the bottom frame side beam 30 . According to the required deflection requirements, the inclination angle of the inclined plate 14 is adjusted by applying different forces so that the rocker body 12 has corresponding deflection, thereby realizing flexible assembly. For example, if the required deflection is small, the side sill body 12 will be moved higher in the height direction of the vehicle body, so that the force on the inclined plate 14 is small, and the inclination of the inclined plate 14 is relatively small; on the contrary, if the required deflection is large , then the side rail body 12 is further lowered in the height direction of the vehicle body, that is, it is pressed downward, so that the sloping plate 14 is subjected to greater force, and the inclination of the sloping plate 14 is relatively large. The included angle between the horizontal plates 15 is 134°, and the angle will change accordingly according to the adjustment.

In this embodiment, by adding an oblique transitional bending to the rocker body 12, when rigidly connected to the bottom frame side beam 30, there is a certain amount of elastic adjustment, which makes it easier to realize the bonding and Flexible adjustment of the height of the car body; it is also easier to meet process requirements such as deflection changes.

It is understandable that, since one side of the door column 21 needs to be freed for installing the door body, only one side is connected to the lower beam 11 , and for the middle column 20 , both sides are connected to the lower beam 11 .

As shown in FIG. 3 , the connecting plate 40 is L-shaped or T-shaped, and the L-shaped connecting plate 41 is used to connect between the end of the lower beam 11 and the door column 21 ; the T-shaped connecting plate 42 is used for It is connected between the middle column 22 and the ends of the lower beam 11 located on both sides of the middle column 22 in the lateral direction. By designing different shapes of the connecting plates 40 to adapt to different connecting positions, of course, the middle column 22 and the lower beams 11 on both sides thereof can also be connected by a cross-shaped connecting plate 40.
