An embodiment of the present disclosure provides a swing-in type of door structure of a vehicle that includes a door disposed in parallel at both sides of an entrance of a vehicle, and a door arm mounted on one side of the door to open or close the door by rotation, including: a center door bracket of which one end is fixed to one surface of an upper center of the door and that extends in a direction perpendicular to the door; a roller bracket of which one end is coupled to the other end of the center door bracket in a direction perpendicular to the center door bracket; and a roller mounted on the other end of the roller bracket and coupled to be rolled and rotated while in contact with a rail formed on a vehicle body of an upper side of the door.

A door opening assembly is provided for moving a door of a vehicle between an open position and a closed position. The assembly includes a frame member coupled to the vehicle, a link is coupled to the frame member, and a link arm pivotally coupled to the link. A pivot arm is pivotally coupled to the frame member and a pivot bracket is pivotally coupled to the door and the pivot arm. The pivot bracket includes a slot such that a pin on the link arm slides therethrough. The assembly includes a gear rack and a gear operably coupled to the gear rack. The gear is driven by a motor as the door moves between its open and closed positions. The assembly further includes a guide track coupled to the vehicle and a roller rotatably driven along the guide track as the door moves between its open and closed positions.

A hinge structure may comprise a first assembly including a central post with an outer surface and a first connector element on the central post for mounting on a first structure, a second assembly pivotally coupled to the first assembly and including a ring extending about the central post, a ring connector connected to the ring, and a second connector element on the ring for mounting on a second structure. A braking element may apply a selectable amount of resistance to pivot movement of the second connector element with respect to the first connector element and including a friction pad extending about a portion of the central post, a pressure band for pressing the friction pad against the central post, and a connecting structure connecting the ends of the band and being adjustable to move the ends closer toward each other and to relax the ends away from each other.

An eccentric hinge includes a rail, a stop block arranged on a first end of the rail, a fixing rod parallel with the rail, a sliding block, a connecting rod and a transmission rod, where the sliding block is arranged on the rail; a first end of the connecting rod is connected with a second end of the rail; a second end of the connecting rod is connected with the fixing rod; a first end of the transmission rod is connected with the sliding bock; a second end of the transmission rod is connected with the connecting rod; when the eccentric hinge is in a closed state, a first centerline of the fixing rod and a second centerline of the rail are parallel lines in a same plane; and a distance between the parallel lines is greater than 0 mm and less than or equal to 10 mm.

The present disclosure relates to a hinged door for utilizing space. The hinged door includes a hinge installed at one side of an opening of a structure; a door of which one end is connected to the hinge to open and close the opening in a hinged manner, and configured to be divided into a plurality of unit panels, each unit panel connected slidably to an adjacent unit panel in an opening/closing direction to stretch/retract in the opening/closing direction; and a connection link of which a first hinge axis of one end is connected to the structure and of which a second hinge axis of the other end is connected to the unit panel of a distal end, of the plurality of unit panels, so that a length of the door is stretched/retracted in the process of hinge opening/closing the door, thereby providing a hinged door for utilizing space.

An extended range sliding door hinge may include a track bracket assembly and an intermediate bracket. The track bracket assembly is sized to be operatively received by a vehicle door track assembly. A first end of the intermediate bracket is movably mounted to the track bracket assembly so that the intermediate bracket may be moved with respect to the track bracket assembly between a retracted position and an extended position. A second end of the intermediate bracket is sized to operatively engage a vehicle sliding door. The extended range sliding door hinge allows the vehicle sliding door to be moved between a standard position when the intermediate bracket is in the retracted position and an extended position when the intermediate bracket is in the extended position.

A hinge assembly includes a first arm, a second arm, a rotatable pin coupling, and a power transfer conduit. The rotatable pin coupling rotationally couples the second arm to the first arm. The first arm defines a first portion of a channel, the second arm defines a second portion of the channel, and rotatable pin coupling defines a third portion of the channel. The power transfer conduit extends through the first portion of the channel at the first arm, the third portion of the channel at the rotatable pin coupling, and the second portion of the channel at the second arm.
