Problems solved by technology

However, due to the ever-changing appearance of the body and the diversification of the body shape, the external structure of the side wall may be very complicated.
Due to the limitations of the stamping process level and the performance limitations of the body materials, some parts of the outer panels of the body cannot be manufactured as a whole.
Especially for the side wall and rear external structure of some cars with changeable curved surface shape, the overall side wall design cannot be fully realized

Embodiment Construction

[0013] see figure 1 , the rear lower cover of the overall side wall outer panel of the car body is a box-shaped drawn part structure, and its four sides have four drawn flanges E, F, G, H formed by drawing. The corners of the cover surface are wrinkled, and the four corners A, B, C, and D of the box-shaped drawn part are designed to have openings, and the openings are still designed as partial tensile structures, and the tensile height h of the corners is much lower than that The height h` of a drawn flanging can ensure the integrity of the surface design of the cover.

[0014] see figure 2 , the drawing flange F is overlapped with the outer panel J of the side wall, and connected by spot welding, K is the spot welding part, I is the rear lower cover plate of the side wall, and the other three drawing flanges E, G, H are respectively connected to the side wall All relevant parts at the rear of the enclosure are connected by spot welding.

Abstract

The invention is a rear lower cover plate of whole side wall shell of a car body, and it is of a box drawn component structure, its four side surfaces have drawn flangings, the corners of the box draw component are designed with openings, locally drawn, the drawing heights of the corners are smaller than those of the four drawn flangings, one drawn flanging of the box drawn component is lap-jointed and spot-welded with the side wall shell and the other three drawn flangings are spot-welded with various accessories in the rear of the side wall.

Description

technical field [0001] The invention relates to the structure of the rear lower cover plate of the side wall of the outer cover of the car body. Background technique [0002] Integral side panels are widely used in the design of side panels for automotive exterior panels with steel sheet body structures. This provides a great guarantee for the integrity and beauty of the body shape, as well as the stability and reliability of the external quality. At present, most of the various cars in various countries in the world have adopted the overall side wall outer panel design. However, due to the ever-changing appearance of the body and the diversification of the body shape, the external structure of the side wall may be very complicated. Due to the limitations of the stamping process level and the performance limitations of the body materials, some parts of the outer panels of the body cannot be manufactured as a whole. Especially for the side wall and rear external structure ...
