The invention relates to the field of metro door leaf door opening mechanisms, in particular to an electric door opening mechanism which comprises a frame body assembly, a door leaf assembly and a door leaf assembly. An ejector rod and a rotating shaft; one end of the pushing assembly is hinged to the base, and the other end of the pushing assembly is hinged to the middle section of the ejector rod; one end of the manual rod is matched with the two ratchet wheels, and the other end of the manual rod extends by a preset distance in the direction away from the ejector rod. And the emergency ejection mechanism comprises a first driving part and a first telescopic rod, the first driving part is fixed on the first mounting plate and right faces the ejection rod, the first telescopic rod is connected with the first driving part, and the first driving part is arranged to be capable of driving the first telescopic rod to stretch out and draw back by a preset length. According to the invention, internal extrusion and external pulling can be realized by effectively utilizing the self structural configuration, whether the fully-open door leaf is stuck or not can be detected, and the probability of opening the fully-open door leaf can be improved in emergency.
本申请涉及地铁门扇开门机构领域,更具体地涉及一种电动开门机构,其中电动开门机构,包括:一架体组件;一顶杆,一转动轴;一推动组件,推动组件的一端与底座铰接,另一端与顶杆的中段铰接;一手动杆,手动杆的一端与两棘轮相配合,另一端往背离顶杆的方向延伸预定距离;以及一应急顶出机构,应急顶出机构包括一第一驱动部件和一第一伸缩杆,第一驱动部件被固定在第一安装板上,并正对顶杆,且第一伸缩杆与第一驱动部件相连,且第一驱动部件被设置能够带动第一伸缩杆伸缩预定长度。本发明能通过有效地利用其自身的结构配置实现内挤外拉、能够检测全开式门扇是否卡死、能在危急情况下提高打开全开式门扇几率的优势。
