A driving mechanism for a door lock and a door lock are provided. The driving mechanism includes a motor, a planetary gear assembly, and a cage. The planetary gear assembly includes a ring gear, a planet gear, and a sun gear. The motor is rotatably connected to the ring gear. The planet gear is further rotatably connected to the sun gear. The planet gear is connected to the cage. When the sun gear is in a fixed state, the ring gear is driven by the motor to rotate. When the ring gear is in a fixed state, the sun gear, the planet gear, and the cage are configured to cooperate with one another, to make the planet gear rotates relative to the sun gear and the cage rotate.

A locking system is described. The locking system, includes a lock. The lock includes a semi-hard magnet and a hard magnet. The hard magnet is configured to move to open or close the lock, the lock is self-powered using near field communication (NFC), and the lock is digitally controlled using a mobile application.

Electromechanical lock utilizing magnetic field forces. An actuator is moved (1202) from a locked position (260) to an open position (400) by electric power. In the locked position (260), a permanent magnet arrangement directs (1204) a near magnetic field to block an access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1206) the near magnetic field towards a far magnetic break-in field originating from outside of the electromechanical lock. In the open position (400), the permanent magnet arrangement directs (1208) a reversed near magnetic field to release the access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1210) the reversed near magnetic field towards the far magnetic break-in field.

A lock cylinder including a plug, a plurality of key followers, a sensor assembly structured to sense positions of the key followers, and a controller in communication with the sensor assembly. The plug includes a keyway and a plurality of plug tumbler shafts. Each of the key followers is movably seated in a corresponding one of the plug tumbler shafts and includes a sensor interface. The sensor assembly includes a plurality of sensors, each of which includes at least one sensing region. Each of the key followers is associated with one of the sensors via an associative link formed between the sensor interface and the corresponding sensing region. The sensors are structured to generate an output signal indicative of the transverse position of the associated key follower, and the controller is structured to select and perform actions based upon the output signals.

Provided are a lock cylinder and an unlocking key. The lock cylinder includes: a lock housing; a lock core, herein the lock core is rotatably arranged in the lock housing; a locking member, herein the locking member is movably arranged between the lock core and the lock housing and provided with a locking position and an unlocking position; a locking blade, herein the locking blade is movably connected to the lock core and capable of stopping or avoiding the movement of the locking member so as to lock or unlock the locking member; a driving assembly, herein at least part of the driving assembly is movably arranged relative to the locking member, and the driving assembly is capable of stopping or avoiding the movement of the locking member so as to lock or unlock the locking member.

Disclosed is an automatically resettable passive swing bolt lock consisting of a lock body and a key. The key can be inserted into a locking hole of the lock body. In the present invention, the lock body comprises a lock housing, a rotary compartment, a lock cover, a reset spring, a pin spring, a pin, a lock body PCB, a motor, a cam, a reset pusher block, and two locking contacts. In the lock body, the rotary compartment is installed inside the lock housing. The lock body PCB, the motor and the cam are installed in an internal cavity of the rotary compartment formed by the lock cover and the rotary compartment. The invention has a small size and a simple structure, and the motor thereof has low power consumption.

The cylinder lock according to the invention includes a body and, inside it, an inner cylinder unit provided with an inner cylinder. The cylinder lock also includes a generator for generating electricity from the movement of a key inserted in the cylinder lock. The electricity generated is used to identify the key, and the electricity generated is also used in the electric device if opening the cylinder lock is allowed on the basis of the identification of the key. In connection with the generator are also generator shaft system, a channel axis and transmission parts from the channel axis to the generator.

Various embodiments that pertain to signal based arrangement of pin tumbler pins are described. A receiver can receive and process a signal. The signal can indicate an arrangement for the pins of the pin tumblers. With a proper signal, the pins can be placed so that the pin tumbler unlocks. Security measures can be put into place to make sure the signal is a valid signal, such as through employment of a hash function set (e.g., two hash functions).

A lock includes a housing assembly, an actuatable lock assembly and a latching assembly. The actuatable lock assembly is positionable in at least a closed orientation and an open orientation. The latching assembly further includes a latch, a cam and a motor. The latch, having a cam profile, is movable between a locked position and an unlocked position. In the locked position, the actuatable lock assembly is maintained in the closed orientation. In the unlocked position, the actuatable lock assembly is positionable into an open orientation. The cam is rotatably mounted and has a first follower configured to intermittently coact with the cam profile of the latch, to, in turn, move the latch between the locked position and the unlocked position. The motor is coupled to the cam. Actuation of the motor causes rotation of the cam, resulting in movement of the latch between the locked and unlocked positions.
