Door locks mainly consist of mechanical components and electronic modules (smart locks). The core components include the lock cylinder, lock body, panel, and bolt. The mechanical parts are responsible for physical locking, while the electronic parts are responsible for intelligent recognition and operation.
1. Lock Cylinder and Lock Body: The lock cylinder is where the key is inserted. It is classified into A, B, and C levels, with C level being the most tamper-proof. The lock body is concealed inside the door and drives the bolt's extension and retraction.
2. Panel and Handle: The outer casing, commonly made of zinc alloy or stainless steel, protects the internal parts. The handle is used to press down to open the door.
3. Smart Module: Smart locks add a circuit board, fingerprint or facial recognition sensor, motor, and battery. The motor is responsible for driving the bolt's opening and closing.
