Electronic lock

Abstract

The invention discloses an electronic lock, comprising a lock body mechanical unit and an electronic control system, wherein the electronic control system comprises a circuit control unit, a power supply management unit and a vibration energy collection unit; the lock body mechanical unit, the power supply management unit and the vibration energy collection unit are electrically connected with the circuit control unit; the circuit control unit controls an unlocking or locking action of the lock body mechanical unit according to a received instruction; the power supply management unit comprises at least one battery and a charging unit; the power supply management unit supplies power to the circuit control unit, and cuts off power in a situation that the battery voltage is lower than a limiting value; the vibration energy collection unit converts mechanical energy to electric energy, and provides a working power supply for the circuit control unit. The electronic lock provided by the invention converts the vibration mechanical energy to the electric energy, and provides power for the circuit control unit, thereby avoiding an insufficient power phenomenon which occurs in the long-term use of the electronic lock.

Description

technical field [0001] The invention relates to the field of electronic locks, in particular to an electronic lock applied to transportation tools such as containers. Background technique [0002] In the process of cargo transportation, logistics companies generally install electronic locks on containers, tank trucks or other box-type vehicles for the safety of cargo transportation. At the same time, in order to meet the needs of intelligent monitoring, in addition to integrating the main control chip and motor control circuit, the internal circuit of the electronic lock also adds GPS modules, GPRS modules, etc., but the addition of more functional modules will increase the consumption of battery power and shorten the electronic life. In addition, the volume of the electronic lock is limited, and the capacity of the battery is fixed, so that the battery power supply is insufficient to complete the monitoring during the entire transportation, and the safety of the goods canno...
