Abstract
A door lock with both manual and electric unlocking functions includes a lock body and a transmission rod. The lock body is provided with a latch for locking a door leaf. The transmission rod is in a transmission connection with the latch. When the transmission rod is manually or electrically driven to rotate forward or backward, the transmission rod is configured to drive the latch of the lock body to retract or extend, thereby achieving opening or closing of the door leaf. The door lock further includes a first housing, a rotating disc, and a rotating member. A misalignment device is arranged between the rotating disc and the rotating member. The misalignment device includes an idling area and a block, a controller, and a drive motor. The door lock further includes a positioning member fixedly arranged on the first housing.
