Embodiment Construction

[0030] Below, according to Figure 1A ~ Figure 6B , a rear opening structure of a vehicle according to an embodiment that actualizes the present disclosure will be described. Figure 5A and Figure 5B Indicates a comparative example. In addition, when describing each drawing, front and rear represent the front-rear direction of the vehicle, up and down represent the vertical direction of the vehicle, and left and right represent left and right when the vehicle is viewed from behind.

[0031] The rear opening structure for attaching the rear door at the rear of the vehicle is composed of a plurality of stacked metal plates. In detail, such as Figure 1A As shown, the roof panel 11, the side member panel 12, and the trough 13 constitute the exterior design surface of the vehicle by the presence of the roof panel 11, the side member panel 12, and the trough 13 at the outermost sides of the rear opening structure of the vehicle.

[0032] The ceiling panel 11 is disposed at an u...

Abstract

In a rear opening structure of a vehicle, a roof panel and a trough are arranged on an upper end of an opening for coupling a back door. Each of left and right ends of a vertical wall of the roof panel in the width direction includes a welding point where the roof panel and the trough are welded to each other. Beads that extend in the vertical direction are provided such that each of the beads isarranged in a vicinity of one of the welding points of the left and right ends of the vertical wall and on an inner side of the one of the welding points of the left and right ends. An end of each bead in the vertical direction is connected to at least one of a rear end surface and a horizontal wall of the roof panel.

Description

technical field [0001] The present disclosure relates to a rear opening configuration of a vehicle and a method of manufacturing the same. Background technique [0002] The rear opening configuration at the rear of the body of the vehicle is formed by welding a plurality of metal sheets at welding spots at a plurality of locations. Japanese Unexamined Patent Application Publication No. 2015-147456 proposes an opening structure at the rear of the vehicle body that reduces the weight and ensures high rigidity while reducing the weight due to the torsion of the vehicle body by using fewer reinforcing components. [0003] However, in the vehicle, in order to prevent excessive force from the road surface from being applied to the vehicle body when the vehicle is running on the road, a shock absorber is provided between the vehicle body and the tires. Depending on the ride comfort of the vehicle, the characteristics of the shock absorber are adjusted. If the input from the shock...
