ELECTRONIC DOOR LOCK HAVING BIDIRECTIONAL OVERRUNNING CLUTCH AND USE METHOD THEREOF

摘要

The present invention relates to an electronic door lock having a bidirectional overrunning clutch. In some embodiments, the electronic door lock having the bidirectional overrunning clutch comprises a first door locking mechanism, a second door locking mechanism, a third door locking mechanism, and a bidirectional overrunning clutch. A user uses the first door locking mechanism from the outside of a door to drive an inner rotary wheel by means of a first torque and to drive a rotary shaft to operate an electronic door lock mounted on the door. The user uses the second door locking mechanism from the inside of the door to drive the inner rotary wheel by means of the first torque and to drive the rotary shaft to operate the electronic door lock. The user uses the third door locking mechanism to drive an outer rotary wheel by using an electronic mode nearby the electronic door lock and operates the electronic door lock by means of the bidirectional overrunning clutch. The outer rotary wheel in the bidirectional overrunning clutch can coaxially rotate around the rotary shaft. When the outer rotary wheel rotates under the drive of a second torque, the outer rotary wheel drives the inner rotary wheel and the rotary shaft to rotate in same direction, so as to control locking and unlocking of the electronic door lock. The three door locking mechanisms do not interfere with each other.
