The invention discloses an automatic door opening device for a vertical hinged door, and relates to the technical field of automatic door openers, the automatic door opening device comprises a door opening mechanism mounted in a door frame cross beam, the door opening mechanism comprises a gear motor, a flat spiral spring, a spring shell and a shaft connecting piece, the flat spiral spring is sleeved on an output shaft of the gear motor, the spring shell covers the outer side of the flat spiral spring, and the shaft connecting piece is connected with the spring shell. One end of the flat spiral spring is connected with the output shaft, the other end of the flat spiral spring is connected with the spring shell, the output shaft is connected with the door leaf through the shaft connecting piece, and the gear motor can drive the output shaft to rotate to open and close the door leaf. When the door leaf is in an open state, the flat spiral spring is in a tightened state, and otherwise, the flat spiral spring is in a loosened state. The automatic door opening device for the vertical hinged door has the power-off door closing function and can be installed in a door frame cross beam in a hidden mode, the service life is prolonged, and the overall shape of a door leaf is prevented from being damaged.
本发明公开一种平开门用自动开门装置，涉及自动开门器技术领域，包括安装于门框横梁内的开门机构，其包括减速电机、平面涡卷弹簧、弹簧壳体和轴连接件，平面涡卷弹簧套设于减速电机的输出轴上，弹簧壳体罩设于平面涡卷弹簧的外侧，且平面涡卷弹簧的一端与输出轴连接，另一端与弹簧壳体连接，输出轴通过轴连接件与门扇连接，减速电机能够带动输出轴转动以实现门扇的开关；当门扇处于打开状态时，平面涡卷弹簧处于缩紧状态，反之则处于放松状态。本发明平开门用自动开门装置具有断电关门功能，还能够隐藏安装在门框横梁内，延长使用寿命，且避免破坏门扇的整体造型。
