PURPOSE: A bicycle lock using an acceleration sensor is provided to enhance the user convenience since if an acceleration sensor operates, then a lock function is operated and thus if acceleration is sensed, corresponding information is informed to an owner through a mobile phone. CONSTITUTION: A bicycle lock using an acceleration sensor comprises generators(11,12), a converter(13), a battery(14), an inverter(15), an acceleration sensor(20) and a controller(40). The generator converts the kinetic energy of a wheel to an electric energy. The converter the electric energy transferred from the generator to DC power supply. The battery charges the DC power supply supplied from the converter. The inverter regularly supplies the power from the battery. The acceleration sensor receives the power from the inverter and senses the acceleration of the bicycle. The controller receives the power from the inverter and supplied the acceleration information using the acceleration input from the acceleration sensor. |
