Abstract

The invention discloses a corner structure located above the tailgate of a vehicle. It includes: a roof panel, which constitutes the roof; a rear roof outer beam, which is arranged at the rear of the roof panel inside the compartment and extends along the width direction of the vehicle; a rear roof inner beam, which is connected to the rear roof outer beam and is connected with it A closed combined shape is formed; the door post reinforcement is integrally installed with the tailgate hinge reinforcement member on its outer side; the inner corner extension part is connected with the door post reinforcement and forms a closed combined shape with it.

Description

technical field [0001] The present invention relates to a rear body structure of a vehicle. Background technique [0002] Such as Figure 5 As shown, the corner position 50 (hereinafter referred to as the corner position 50) above the tailgate of the vehicle is as follows in the prior art figure 2 shown. exist figure 2 Among them, the upper end of the tailgate pillar reinforcement 20 along the inner side of the vehicle width is connected to the rear roof outer cross member 21 by welding. Moreover, in the corner portion 50, except that the tailgate pillar reinforcement 20 and the rear roof outer beam 21 are connected by welding, the upper end portion of the outer side panel 41 (see Figure 4 ) is also connected by welding. Figure 4 means along the figure 2 A cross-sectional view of line B-B in . [0003] Such as Figure 4 As shown, the tailgate hinge 44 on which the tailgate 51 is mounted is mounted on the rear roof outer cross member 21 . However, it is dangerous...
