Intelligent door lock system with a torque limitor

摘要

An intelligent door lock system has a drive shaft of a lock device. A circuit is coupled to the drive shaft. A torque limiter is coupled to the circuit. The torque limiter is configured to reduce excessive force being applied to components of the intelligent door lock system. A motor is coupled to the circuit.

主权项

1. An intelligent door lock system with components at a dwelling, comprising:
a drive shaft of a lock; a position sensor coupled to the drive shaft, the position sensor configured to detect a position of the drive shaft; a processor coupled to a wireless communication system; an energy source coupled to a circuit; an engine with a memory coupled to the position sensor, the engine configured to execute software instructions relative to the position sensor; a motor coupled to the drive shaft; a torque limiter with an input from gears that are coupled to the motor and limits torque applied to the motor, a ramp-up speed being applied when a first component initially engages with a second component that provides an output, the steady state speed being applied following an initial engagement and is an operational speed during a standard operation mode, and the ramp down speed is applied as the first and second components begin a state of non-engagement; and wherein when a user's mobile device is at an exterior of the dwelling and in a close proximity to the dwelling the drive shaft is caused to rotate by the engine and the energy source to provide an unlocking of the door when the door is in a locked state.
