Door machine mechanism for rolling door having functions of fireproof, smokeproof, and fire escape
摘要：
A door machine mechanism for a rolling door has an electric machine mechanism, a brake mechanism and an output mechanism. In normal power supply condition, the rolling door is opened by the electric machine mechanism. In case of fire, the brake mechanism releases brake so that the rolling door moves downward by its own weight. However, in an emergency condition, if an external force is applied to push the door upward, the rolling door will be reopened by an assistance of spare electricity to the electric machine mechanism.
摘要（中）：

一种用于卷帘门的门机机构具有电机机构，制动机构和输出机构。 在正常供电状态下，滚动门由电机机构打开。 在发生火灾的情况下，制动机构释放制动器，使得滚动门以其自身的重量向下移动。 然而，在紧急情况下，如果施加外力以向上推动门，则通过辅助电力重新打开滚动门到电机机构。
