The invention discloses a door blade opening-closing structure. The door blade opening-closing structure comprises a door blade assembly and also comprises a sliding rail assembly; one end of the sliding rail assembly is hinged to the upper ridge of a door opening machine while a driving mechanism is arranged at the other end of the sliding rail assembly for driving the sliding rail assembly to swing up and down in a reciprocating mode; the door blade assembly comprises a bottom plate, a first blade, a second blade, a first connecting rod and a second connecting rod; the bottom plate is fixedon a car door hanging plate of a door opening machine; the two ends of the first connecting rod are hinged to the upper parts of the first blade and the second blade respectively; the two ends of thesecond connecting rod are hinged to the lower parts of the first blade and the second blade respectively; the middle parts of the first connecting rod and the second connecting rod are both hinged tothe bottom plate; the upper part of the first blade is hinged to a sliding block; the sliding block is in sliding connection with the sliding rail assembly; when the door is closed properly, the swinging end of the sliding rail assembly swings upwards, the first blade is pulled upwards through the sliding block, and the first blade and the second blade are closed; and when the door is opened, theswinging end of the sliding rail assembly swings downward until the sliding rail assembly is parallel to a motor driving belt, and the door blade assembly is opened.

    本发明公开了一种门刀开闭结构,包括门刀组件,还包括滑轨组件,滑轨组件一端铰接于开门机上坎,另一端设有驱动机构,驱动滑轨组件上下往复摆动,门刀组件包括底板、第一刀片、第二刀片、第一连杆和第二连杆,底板固定在开门机的轿门挂板上,第一连杆的两端分别铰接与第一刀片和第二刀片的上部,第二连杆的两端分别交接于第一刀片和第二刀片的下部,第一连杆和第二连杆的中部均铰接于底板,第一刀片的上部铰接有滑块,滑块与滑轨组件可滑动连接,关门到位时,滑轨组件的摆动端向上摆动,通过滑块向上拉动第一刀片,第一刀片和第二刀片闭合;开门时,滑轨组件的摆动端向下摆动至滑轨组件与电机传动带平行,门刀组件打开。
