Abstract

The present application relates to a door lock and a control circuit thereof. The door lock includes a switch means, a switch driving means capable of opening the switch means, and a driving slider. The driving slider is capable of driving the switch driving means. The driving slider is capable of being driven by a door hook. The switch driving means (that is, a swing lever) and a lock pin are capable of jointly controlling opening of the switch means. The switch driving means (that is, the swing lever) is driven by a mechanical structure (that is, the driving slider), and the lock pin can be driven by an electronic signal and a circuit structure (for example, a second current loop), thereby improving the sensitivity and reliability in disconnecting the power supply under abnormal working conditions.
