Unlocking driving circuit, electric control lock and magnetic lock
The invention discloses an unlocking driving circuit, an electric control lock and a magnetic lock, wherein the unlocking driving circuit comprises a first relay, a first resistor, a first capacitor,a first diode and a first transient diode, wherein an anode of the first diode is electrically connected to a contact of the first relay; and a cathode of the first transient diode is electrically connected to a cathode of the first diode, an anode of the first transient diode is grounded, and the cathode and the anode of the first transient diode are connected to two signal input ends of the electric control lock respectively. According to the unlocking driving circuit, the electric control lock and the magnetic lock, power supply is realized at an instant when the electric control lock is powered on by the first capacitor, so that a voltage fluctuation of a power supply source caused by a large demand for a transient current can be avoided; circuit one-way breaking-over is realized by the first diode, so that an impact influence caused by a reverse electromotive potential of a coil of the electric-control lock on the circuit can be avoided; and the first transient diode can limit thevoltage of the reverse electromotive potential at a preset value or so.
本发明公开一种开锁驱动电路、电控锁以及磁力锁，其中，开锁驱动电路包括：第一继电器、第一电阻、第一电容、第一二极管以及第一瞬态二极管，所述第一二极管的阳极与所述第一继电器的触点电连接；所述第一瞬态二极管的阴极与所述第一二极管的阴极电连接，所述第一瞬态二极管的阳极接地，所述第一瞬态二极管的阴极以及阳极分别连接电控锁的两个信号输入端。本发明通过第一电容为电控锁通电瞬间供电，能够避免瞬时电流大需求而造成供电电源的电压波动，通过第一二极管使的电路单向导通，避免电控锁的线圈产生的反相电动势对电路的冲击影响，且能通过第一瞬态二极管把反向电动势的电压限制在预设值左右。
