The output power of the power generating unit 32 is filtered and regulated for storing the power generated by the power generating unit 34 for use. Since the output power of the power generating unit 34 is rectified by the rectifying unit 33 and is a DC power source, the energy storage unit 34 can be configured using a conventional electric energy storage device such as a capacitor or a secondary battery. The energy storage unit 34 is further coupled to the identification module 2 to provide the power required by the identification module 2 .

With the above system, the preferred embodiment of the door lock system of the present invention authenticates the user by an identification module 2, and controls the state of locking or unlocking a door lock module 1; using an energy collecting module 3 The kinetic energy of the handle 111 of the door lock module 1 is recovered by the user, and is converted into electric energy by a power generating unit 32 and stored in an energy storage unit 34.
