The invention relates to the technical field of enterprise management, and discloses a self-locking door capable of reducing door closing noise based on an electromagnetic principle. The self-lockingdoor comprises a door frame, wherein a door plate is movably hinged to the right end of the door frame, and a fixing frame is fixedly installed at the upper end of the interior of the door plate. According to the self-locking door, when the door plate is closed, a gear is rotated to drive a toothed plate to move rightwards in the fixing frame, the toothed plate drives a sliding rod at the left endto move rightwards together, meanwhile, a capacitor plate is driven to be opposite to an electrode plate, the area, opposite to the electrode plate, of the capacitor plate is reduced, the electric quantity passing through the capacitor plate is slowly reduced, then a signal is transmitted to an electromagnet, the voltage on the electromagnet is reduced, the magnetism is weakened, the repulsive force on a permanent magnet block is gradually reduced along with the increase of the distance, away from the electrode plate, of the capacitor plate, so that noise generated on the door frame loaded onthe door plate during door closing is avoided, and the magnetic repulsive force is used for replacing the buffering force of a spring so that the service life of an access control device can be better prolonged.
本发明涉及企业管理技术领域，且公开了一种基于电磁原理降低关门噪音的自锁门，包括门框，所述门框的右端活动铰接有门板，所述门板内部的上端固定安装有固定框。该装置通过在关闭门板时，转动齿轮转动的，带动齿板在固定框中向右运动，齿板带动左端的滑动杆一起向右运动，同时带动电容板原理电极板，电容板正对于电极板的面积变小，其上通过的电量缓慢减小，从而将这一个信号传递到电磁体上，电磁体上的电压减小，磁性减弱，对于永磁块的排斥力随着电容板远离电极板的距离增大而逐渐减小，避免了在关门中门板装载门框上产生噪音，而且利用磁性排斥力代替弹簧的缓冲力，从而可以实现了更好延迟门禁装置的使用寿命。
