Door lock with both manual and electric unlocking functions

A door lock with both manual and electric unlocking functions, comprising a lock body and a transmission rod;

• wherein 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, wherein opening or closing of the door leaf is achieved;
• the door lock further comprises a first housing, a rotating disc rotatably arranged on the first housing, and a rotating member;
• wherein rotatory central lines of the transmission rod, the rotating disc, and the rotating member overlap;
• the transmission rod is in a transmission connection with the rotating member;
• a misalignment device is arranged between the rotating disc and the rotating member;
• the misalignment device comprises an idling area and a block extending into the idling area;
• the block is configured to move within the idling area;
• the idling area and the block are arranged at the rotating disc or the rotating member in an alternative manner;
• when the transmission rod is manually driven to rotate forward or backward, and the rotating member is driven to rotate forward or backward, the idling area provides a moving space for the block, enabling the rotating member to rotate relative to the rotating disc;
• the door lock further comprises a controller and a drive motor communicated with the controller;
• the drive motor is configured to drive the rotating disc to rotate and is fixed on the first housing;
• when the controller receives an indication signal for opening or closing a door, the controller is configured to control the drive motor to drive the rotating disc to rotate forward or backward;
• the rotating disc rotating forward or backward is configured to, with a help of the misalignment device, drive the rotating member to rotate forward or backward;
• the rotating member rotating forward or backward further drives the transmission rod to rotate forward or backward, wherein the opening or closing of the door is achieved;
• and
• the door lock further comprises a positioning member fixedly arranged on the first housing;
• wherein the rotating member is arranged between the rotating disc and the positioning member;
• and the rotating disc and the positioning member provide axial positioning for the rotating member, and the rotating disc or the positioning member provides radial positioning for the rotating member.
