The present invention relates to an electromechanical lock assembly (1) comprising a lock body (15), a lock core (17), a lock bolt operating member (19), and an electronic access control device. The electromechanical lock assembly further comprises an annular element (27) which is rotatably and axially displaceably mounted on said lock core (17), a coupling device (25) arranged to communicate with said electronic access control device and, upon the insertion of an appropriate key (65) in a key receptacle (37) of the lock core (17), rotationally lock the annular element (27) to the lock core (17), thereby enabling rotation of the lock core (17) in a first direction and thereby enabling unlocking of a lock (3) with said appropriate key (65), and a blocking arrangement (63) arranged to prevent unauthorized unlocking of said lock (3).

A lock can include a motor assembly, a gear assembly, and an unlocking assembly. The motor assembly can include a motor and a drive shaft. The gear assembly can include a cam, a pinion gear, and a pinion. The pinion gear can include a plurality of teeth disposed along only a portion of a perimeter of the pinion gear. The pinion gear can be configured to engage the pinion. The pinion can be configured to translate laterally to release a biasing member to unlock a door of a container.

One embodiment provides an electrical key for locking and unlocking an electrical lock. The electrical key includes an energy-transfer unit that includes a magnetic core and a coil wrapped around the magnetic core, a pulse generator configured to generate a first pulse sequence including alternating pulse on and pulse off cycles and a second pulse sequence comprising a continuous pulse train, and a modulator driver configured to modulate a voltage or current on the coil using the generated first or second pulse sequence, a measurement module configured to measure a current or voltage on the coil excited by the modulated voltage or current, respectively, a key-position determination module configured to determine a relative position between the electrical key and the electrical lock based on the measured current or voltage, and a communication interface for communicating with the electrical lock to facilitate the locking and unlocking of the electrical lock.

Lock system, mobile device and method for indicating the location of a lock with a mobile device, which mobile device sends and receives a radio signal and communicates with the lock via radio-frequency communication, wherein the lock is a lock that is openable electrically and by radio-frequency communication. In the solution of the invention the direction and/or strength of a radio transmission sent by a lock is measured with a mobile device, the location and/or direction of the lock in relation to the mobile device is determined on the basis of the measurement, and the location of the lock and/or the direction towards the lock is indicated with the mobile device to the user of the mobile device.

A door lock includes a latch device and inner and outer operating devices operatively connected to the latch device. The inner operating device includes a control module and a first battery module electrically connected to the control module and supplying electricity for operation of the door lock. A detecting module is electrically connected between the first battery module and the control module. The outer operating device includes a first electric connecting device electrically connected to the detecting module and an unlocking information input module electrically connected to the control module. When the remaining electricity of the first battery module detected by the detecting module is lower than a preset alarm value and a second electric connecting device of a mobile device is in electrical connection with the first electric connecting device, the second battery module of the mobile device supplies electricity to the door lock for operation.

An electric lock system, includes an electric lock and an electric key. The electric lock includes a lock body and a lock core, and the lock body has a key limit slot and a key limit slide. The lock core includes a T-shaped magnet, a solenoid and a lock pin. The T-shaped magnet is fixed to the lock core, and the lock pin is connected to the solenoid, the solenoid can generate a magnet field when energized, and the magnet field generate a force with the T-shaped magnet, and drives the lock pin to stop limiting the lock body. The electric key includes a lithium battery and a metal housing, and the metal housing has a key limit head corresponding to a shape of the key limit slot. The electric key provides electric power to the lock core by contacting the key limit head to the key limit slot.

A lock can include a motor assembly, a gear assembly, and an unlocking assembly. The motor assembly can include a motor and a drive shaft. The gear assembly can include a cam, a pinion gear, and a pinion. The pinion gear can include a plurality of teeth disposed along only a portion of a perimeter of the pinion gear. The pinion gear can be configured to engage the pinion. The pinion can be configured to translate laterally to release a biasing member to unlock a door of a container.
