Abstract

An intelligent door lock system is provided with a position sensing device configured to be coupled to a drive shaft of a lock device. The position sensing device senses position of the drive shaft and assists in locking and unlocking a lock of a lock device. An engine is provided with a memory coupled to the positioning sensing device. A circuit is coupled to the engine and an energy source is coupled to the circuit. A device converts energy into mechanical energy and is coupled to the circuit, positioning sensing device and the drive shaft. The device that converts energy is coupled to the energy source to receive energy from the energy source. A wireless communication bridge is in communication with a first wireless communication device that communicates with Network Systems, and a second wireless communication device in communication with the wireless communication bridge.

Claims

1. An intelligent door lock system at a dwelling with a door, comprising:

a position sensing apparatus configured to be coupled to a drive shaft of a lock, the position sensing apparatus sensing position of the drive shaft to assist in locking and unlocking a lock of a lock apparatus;

an engine with a memory coupled, the engine being coupled to the positioning sensing apparatus, the memory includes states of the door used with the position sensing device to determine if the lock is locked or unlocked;

a circuit coupled to the engine;

an energy source coupled to the circuit; and

an apparatus that converts energy into mechanical energy coupled to the circuit, positioning sensing apparatus and the drive shaft, the apparatus that converts energy being coupled to the energy source to receive energy from the energy source;

a wireless communication device coupled to the engine, the wireless communication device that utilizes audio and RF communication to communicate with a wireless device with the audio used to communicate a security key to the intelligent door lock system from the wireless device and the RF increases a wireless communication range to and from the wireless communication device;

wherein the wireless device is a mobile device of a user occupant of the dwelling is configured to be in communication with the wireless communication device and the door lock mechanism to provide locking or unlocking of the door; and

a non-user occupant third party is allowed controlled access to the dwelling when the user occupant grants access rights to the non-user occupant third party.

2. The system of claim 1, wherein the positioning sensing in operation is coupled to the apparatus that converts energy that provides for moving a bolt of tile lock apparatus to at least one of a locked or unlocked positioned.

3. The system of claim 1, wherein the lock can be manually locked and unlocked.

4. The system of claim 1, wherein the position sensing 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.

5. The system of claim 4, wherein the accelerometer provides

at least one of, a number of times a door is closed or opened, a degree of door physical swing, of the door, and distance of door swing.

6. The system of claim 5, wherein the accelerometer in operation provides a determination as to whether or not someone successfully swung the door open.

7. The system of claim 1, wherein the lock apparatus can be locked or unlocked wirelessly remotely.

8. The system of claim 1, wherein the circuit is coupled to at least one of, the processor, the power source, a communication apparatus for a mobile device, the positioning sensing device, a speaker, a temperature sensor, a battery voltage sensor, a current sensor that determines how hard the apparatus that converts energy is working, a protection circuit to protect the apparatus that converts energy from overheating and an LED array.

9. The system of claim 1, further comprising:

wing latches coupled to a chassis of the intelligent door lock system.

10. The system of claim 1, wherein the system is coupled to an intelligent door lock system cloud server.

11. The system of claim 1, wherein the position sensing apparatus is positioned on the drive shaft.

12. A method using an intelligent door lock system at a door, comprising:

coupling a circuit to an engine with a memory that includes states of the door;

using the memory the position sensing apparatus to determine if the lock is locked or unlocked;

providing a wireless communication device coupled to the engine, the wireless communication device utilizing audio and RF communication to communicate with a wireless device with the audio used to communicate a security key to the intelligent door lock system from the wireless device and the RF increases a wireless communication range to and from the wireless communication device;

using a wireless device that is a mobile device of a user occupant of the dwelling is to be in communication with the door lock mechanism to provide locking or unlocking of the door; and

grant to a non-user occupant third party controlled access to the dwelling when the user occupant grants access rights to the non-user occupant third party;

using a device that converts energy into mechanical energy that is coupled to the drive shaft; and

rotating the drive shaft to lock and unlock the lock apparatus.

13. The method of claim 12, further comprising:

installing the intelligent door lock system at a door without a pre-existing lock apparatus.

14. The method of claim 12, further comprising:

communicating using a wireless communication apparatus of the intelligent door lock system.
