Abstract: A folding unit for a foldable vehicle comprises a floor part configured including a front floor provided with a front wheel and a rear floor provided with a rear wheel. The front floor and the rear floor overlap each other or extend by being slid to each other to extend or contract a wheelbase of the vehicle. A rear cabin part is disposed at a rear side of the vehicle to form a dome shaped cabin and has a lower end hinge-coupled with the floor part to rotate in a front and rear direction of the vehicle. A folding driver includes a linear motor rotating while being hinge-coupled with the floor part. An operating rod is extended or contracted from the linear motor and has an end hinge-coupled with a lower end of the rear cabin part.

Abstract: A link unit for a foldable vehicle includes: a windshield part having a lower end hinge-coupled with a floor to rotate in a front and rear direction of a vehicle; a rear cabin part forming a dome-shaped cabin having a lower end hinge-coupled with the floor to rotate in the front and rear direction of the vehicle; a roof part having a rear end hinge-coupled with the rear cabin part and a front end provided with a slot in a longitudinal direction of the vehicle; a linear driver including a motor at an end of the slot, a ball screw extended along the slot, and a ball nut fastened with the ball screw to be slid along the slot; and a connection link having a front end hinge-coupled with an upper end of the windshield part and a rear end connected with the ball nut by a hinge pin.
