An embodiment driving apparatus for a swing door includes a drive shaft that is linearly movable, a drive casing rotatably disposed around the drive shaft, and a conversion mechanism configured to convert a linear movement of the drive shaft into a rotational movement of the drive casing, wherein the conversion mechanism includes a first spiral groove provided in an exterior surface of the drive shaft, a second spiral groove provided in an interior surface of the drive casing, and a plurality of balls interposed between the first spiral groove and the second spiral groove.

Doors on a vehicle may be controlled by a door positioning system that moves the doors freely and fluidly relative to the body of the vehicle. The doors may include front and rear doors on each side of the vehicle. The door positioning system may control the movement and positioning of each door using a door mechanism coupled between the door and the body of the vehicle. The door positioning system may determine a position or path of motion for each door based on sensor data and user input. The door positioning system may issue corresponding control signals to actuators in the door mechanism to position the door accordingly. For example, the front door may slide open at an angle to accommodate an angled tire. Front and rear doors may open in opposite directions to create a large, unobstructed space for passengers to enter and exit the vehicle.

Universal rotary actuators (URAs) and door assemblies having the URAs are disclosed. In some embodiments, the URA includes a motor, a worm gear driven by the motor, a worm wheel having teeth that mesh with threads of the worm gear, a pinion gear attached to the worm wheel, drive gear rotatably connected to the pinion gear, an output shaft attached to the drive gear, and a controller assembly disposed between the drive gear and the motor, the controller selectively controlling direction and speed of the motor. In some embodiments, the URA additionally includes a quick release assembly that moves the pinion gear between an engaged position in which the pinion gear is rotatably connected to the drive gear and a disengaged position in which the pinion gear is not rotatably connected to the drive gear.

Loading, shifting, and staging objects in automated or semi-automated fashion including systems, methods, and apparatuses for the same. The embodiments hereof enable automated and/or semi-automated loading, shifting, organizing, staging, and accessing of objects in different environments, e.g., those associated with a logistics network operation. For example, one such environment is a vehicle. In one aspect, a loading mechanism is used to load objects into a storage space of the vehicle. In another aspect, a shifting mechanism is used to shift objects in a storage space of the vehicle. In another aspect, a door assembly allows for automated opening and closing of a door into a storage space of a vehicle. In addition, methods of manufacturing and using the same are provided.

A door opening and closing device for a vehicle includes a door for opening and closing a door opening formed in a vehicle body, a spindle mounted in a longitudinal direction of the vehicle body and configured to rotate, and a door arm of which a first end portion thereof is rotatably connected to a first end portion of the door, and a second end portion may be configured to move and rotate according to a rotation of the spindle.
