Publication number: 20240066962Abstract: A trunk door is divided into two sub-doors to be folded in two steps. Even when it is difficult to open the trunk door due to a small distance between a vehicle and a wall, the trunk door can be easily and conveniently opened or closed. The sub-doors are formed to rotate in the same direction or rotate in the different directions. A length of a rotation radius along which the trunk door rotates is reduced. Thus, the trunk door can be conveniently opened or closed even in a small space. When there is a risk of coming into contact with the wall, since the outer sub-door is rotated in a backward direction to reduce a total rotation radius of the trunk door, the sub-door does not come into contact with the wall. Thus, the trunk door can be easily and conveniently opened or closed.Type: ApplicationFiled: July 20, 2023Publication date: February 29, 2024Applicant: DAEHAN SOLUTION CO., LTDInventors: Choong HO KWON, Moon-Sik JEONG
