The present invention relates to an automatic vertical opening and closing device of a rear wing door of a truck, which vertically divides and separately forms a door for opening and closing an inlet of a loading box of a truck, automatically opens and closes a rear wing door of an upper portion in a vertical direction through an opening/closing unit to prevent the rear wing door from being reopened since the rear wind door is not fully closed or a locking device is not locked during operation, can open/close and lift a lower portion of the loading box through a lower door to easily perform operation when loading and unloading an article, and vertically opens/closes the rear wind door and the lower door to prevent obstruction of passage even in an open state or occurrence of an accident when loading and unloading the article. The automatic vertical opening and closing device of a rear wing door of a truck of the present invention comprises: a rear wing door formed to open and close a loading box of a truck in a vertical direction; an opening and closing unit formed inside the loading box to open and close the rear wing door; a support unit for supporting the rear wing door when the rear wing door is opened; a lower door formed at a lower side of the rear wing door to open and close a rear lower side of the loading box; a lifting unit formed on a rear surface of the loading box to rotate the lower door, and vertically lifting the lower door; a locking unit formed to be locked in a state that the lower door is closed; and a control unit for controlling operation of the opening/closing unit and the lifting unit, and detecting and displaying whether the rear wing door and the lower door are closed through a sensor.
본 발명은 탑차의 적재함 입구를 개폐하는 도어를 상하로 구분하여 따로 형성하고, 상부의 리어윙도어를 상하방향으로 개폐부를 통해 자동으로 개폐하므로, 리어윙도어가 운행중 완전히 닫히지 않거나 잠금장치가 잠겨지지 않아 다시 열리는 것을 방지할 수 있으며, 하부도어로 적재함의 하부를 개폐하며, 승강시킬 수 있으므로, 물건을 싣거나 내릴 때 쉽게 작업할 수 있고, 리어윙도어와 하부도어를 상하 방향으로 개폐하므로, 열린 상태에서도 통행에 방해가 되거나, 물건을 싣거나 내릴 때 안전사고가 발생되는 것을 방지할 수 있는 탑차의 리어윙도어 자동 상하 개폐장치에 관한 것으로서, 탑차의 적재함을 상하방향으로 개폐하도록 형성되는 리어윙도어; 상기 리어윙도어를 개폐시키도록 적재함의 내측에 형성되는 개폐부; 상기 리어윙도어의 개방시 리어윙도어를 지지하도록 형성되는 지지부; 상기 리어윙도어의 하측에 형성되어 적재함의 후방 하측을 개폐시키는 하부도어; 상기 적재함의 후면에 형성되어 하부도어가 회동되도록 하며, 하부도어를 상하 방향으로 승강시키는 승강부; 상기 하부도어가 닫힌 상태에서 잠기도록 형성되는 잠금부 및 상기 개폐부 및 승강부의 작동을 제어하며, 센서를 통해 리어윙도어와 하부도어의 닫힘여부를 감지하여 표시하는 제어부를 포함하는 것을 특징으로 한다.
