[0036] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] See also Figure 1As shown, due to the configuration of rear quarter windows, the Z-dimension from the rear quarter windows to the rear wheels is small, resulting in limited space for the body interface layout, and the waistline cannot be avoided, so that the curved surface corresponding to the waistline position changes in size with the large surface of the quarter window area in the Y direction. The body interface can be set as a charging port or a fuel filler port. For example, if the body interface is set as a fuel filler port, due to the angle limitation of the fuel gun, the upward movement of the fuel filler port affects the turning radius of the fuel filler pipe from behind the tire. The position of the fuel filler port is limited to downward movement due to insufficient safety clearance with the tire. If the flange of the side outer panel is adjusted according to the normal The Y-axis straight punching is standard, and the angle between the side panel appearance surface and the stamping direction is less than 30°. The upper punch of the fuel filler port has a sharp-angle feature, which will result in insufficient mold strength, wrinkling of the side panel appearance surface, and cracking of the reshaped side wall. As a result, the distance between the fillet of the side panel appearance surface and the reshaped side wall cannot meet the size requirements of the fuel filler port. The flange of the side panel outer panel is changed to a bevel shaping at a certain angle. The flange of the side panel outer panel cannot be formed by straight punching along the Y axis, and the reshaped side wall of the flange cannot be tilted downward from the inside of the vehicle to the outside of the vehicle.
