Abstract: An embodiment mobility includes a frame unit, a traveling drive unit disposed at a front or rear side of the frame unit and including a traveling wheel and a suspension module configured to change a position of the traveling wheel relative to the frame unit, and a suspension assistant unit having a first side coupled to the frame unit and a second side coupled to the suspension module, the suspension assistant unit including a wire member configured to pull the suspension module and having a first side coupled to the suspension module.

Abstract: A moving object cabin includes a body having an opening open in a predetermined first direction and defining an internal space communicating with the opening, a cover provided to open or close the opening, and a cover moving part disposed in the internal space of the body and coupled to the cover to move the cover.

Abstract: A wheel structure includes a variable spoke configured to connect a wheel and a central shaft and having a length that varies in a radial direction of the wheel, a spoke driving unit configured to provide power for changing the length of the variable spoke in the radial direction, and a power transmission unit configured to transmit power from the spoke driving unit to the variable spoke. A plurality of variable spokes are spaced apart from one another in the circumferential direction. The power transmission unit includes an output shaft configured to rotate by receiving power from the spoke driving unit, and a clutch configured to connect the variable spoke and the output shaft and selectively transmit a rotational force of the output shaft to the variable spoke or cut off the transmission of the rotational force to the variable spoke.

Abstract: An embodiment seating device includes a frame unit including a chair region capable of supporting a user and a leg region extending downward from the chair region, a backrest unit disposed at a rear side of the frame unit, and a handle unit coupled to a first side of the frame unit, the handle unit including a fixing handle body region having a first side coupled to the frame unit and rotatable relative to the frame unit and a lifting handle body region having a first side coupled to the fixing handle body region and rectilinearly movable relative to the fixing handle body region.

Abstract: A driving wheel includes: a first disc provided to be rotatable with respect to a rotary shaft; a second disc provided to be rotatable with respect to the rotary shaft; a plurality of spokes each protruding outward and each having a first side rotatably coupled to the first disc and a second side rotatably coupled to the second disc; a first motor to rotate the first disc; and a second motor to rotate the second disc.

Abstract: A driving wheel includes: a hub body disposed in a central region of the driving wheel; a plurality of spoke members inserted into the hub body and movable in a radial direction R of the driving wheel relative to the hub body; and link members each having one side coupled to one of the spoke members and the other side coupled to another spoke member disposed adjacent to the spoke member to which the one side of the link member is coupled. In particular, when the spoke members move in the radial direction R, the link members are rotatable about regions coupled to the spoke members.

Abstract: A rear side entry type wheelchair includes a driving device comprising a pair of driving frames provided on left and right sides thereof and driving wheels provided in the driving frames, respectively, a seat device including a pair of horizontal frames coupled to the driving device and saddles configured to be rotated about a vertical shaft on surfaces of the horizontal frames, a back support device including a back support opening/closing interworker provided on a rear side of the seat device and a back support provided in the back support opening/closing interworker configured to be foldable so as to be opened and closed, and a handle device provided on a front side of the seat device.

Abstract: A driving wheel includes: a first disc provided to be rotatable with respect to a rotary shaft; a second disc provided to be rotatable with respect to the rotary shaft; a plurality of spokes each protruding outward and each having a first side rotatably coupled to the first disc and a second side rotatably coupled to the second disc; a first motor to rotate the first disc; and a second motor to rotate the second disc
