Abstract

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.

Claims

1. An intelligent door lock system with components, comprising:

a drive shaft of a lock device;

a processor coupled to a wireless communication device;

an energy source coupled to a circuit; and

a device that converts energy into mechanical energy coupled to the circuit and the drive shaft, the device that converts energy being coupled to the energy source to receive energy from the energy source; and

wherein a ramp-up speed, a steady state speed and a ramp down speed are applied to the device that converts energy into mechanical energy, the ramp-up speed being applied when a first component initially engages with a second component, the steady state speed is applied following the initial engagement and is a an operational speed that the device that converts energy uses during a standard operation mode, and the ramp down speed is applied as the first and second components begin a state of non-engagement.

2. The system of claim 1, wherein the steady state speed occurs when the energy source has an output energy that is sufficient to operate the intelligent door lock system.

3. The system of claim 1, wherein the steady state speed occurs when the energy source has an output energy less than 100%.

4. The system of claim 1, wherein the steady state occurs when the energy source has an output energy that is at a maximum energy output sufficient to operate the intelligent door lock system.

5. The system of claim 4, wherein the maximum energy output is less than 100%.

6. The system of claim 1, wherein the steady state speed occurs when the intelligent door lock system is subjected to a temperature range sufficient to operate the intelligent door lock system.

7. The system of claim 1, wherein the intelligent door lock system can only operate between a minimum and a maximum temperature.

8. The intelligent door lock system of claim 7, wherein the steady state speed occurs when the intelligent door lock system is at the temperature from the minimum to the maximum temperature range.

9. The system of claim 1, wherein the ramp-up speed includes a first speed and a second speed.

10. The system of claim 1, wherein the intelligent door lock system is installed to an existing lock system already mounted at a door.

11. The system of claim 1, wherein the intelligent door lock system is installed at a door without a pre-existing lock device.

12. The system of claim 1, further comprising:

a positioning sensing device.

13. The system of claim 1, wherein the position sensing device is an accelerometer.

14. The system of claim 13, wherein the accelerometer determines position of the drive shaft and at least one of, door knocking, picking of the lock, break-in and unauthorized entry, door open and closing motion.

15. The system of claim 13, Further wherein accelerometer does not require additional power than that required for determining the at least one of, door knocking, picking of the lock, break-in and unauthorized entry, door open and closing motion.

16. The system of claim 12, wherein the positioning sensing device in operation is coupled to the motor that provides for moving the bolt of the lock device to at least one of a locked or unlocked positioned.

17. The system of claim 1, wherein a lock of the intelligent door lock system can be manually locked and unlocked.

18. The system of claim 12, wherein the position sensing device is selected from at least one of, an accelerometer, optical encoder, magnetic encoder, mechanical encoder, Hall Effect sensor, potentiometers, contacts with ticks and an optical camera encoders.

19. The system of claim 1, wherein the lock device of the intelligent door lock system can be locked or unlocked wirelessly remotely.

20. The system of claim 19, wherein the lock device can be locked or unlocked using a mobile device.

21. An intelligent door lock system with components, comprising:

a drive shaft means of a lock device means;

a processor means coupled to a wireless communication device means;

an energy source means coupled to a circuit means; and

a device that converts energy into mechanical energy means coupled to the circuit means and the drive shaft means, the device that converts energy means being coupled to the energy source means to receive energy from the energy source means; and

wherein a ramp-up speed, a steady state speed and a ramp down speed are applied to the device that converts energy into mechanical energy means, the ramp-up speed being applied when a first component means initially engages with a second component means, the steady state speed is applied following the initial engagement and is an operational speed that the device that converts energy means uses during a standard operation mode, and the ramp down speed is applied as the first and second components means begin a state of non-engagement.

22. A method for locking and unlocking a door that has an intelligent door lock system with components, comprising:

providing a drive shaft of a lock device;

using a processor coupled to a wireless communication device;

using an energy source coupled to a circuit; and

using a device that converts energy into mechanical energy coupled to the circuit and the drive shaft, the device that converts energy being coupled to the energy source to receive energy from the energy source; and

operating at a ramp-up speed, a steady state speed and a ramp down speed, the ramp-up speed being applied when a first component initially engages with a second component, the steady state speed is applied following the initial engagement and is a an operational speed that the device that converts energy uses during a standard operation mode, and the ramp down speed is applied as the first and second components begin a state of non-engagement.
