Locking mechanism including energy storage
Certain aspects of the technology disclosed herein include an apparatus and method for storing energy in a electromechanical lock. The electromechanical lock can include a main housing and a deadbolt. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door. The deadbolt can have a hollow inner region configured to receive an energy storage device. The energy storage device within the deadbolt can be electrically connected to the main housing. The energy storage device can be used to power an actuator and/or accelerometer in the main housing.

5. The method of claim 1 , wherein the deadbolt includes a deadbolt cap configured to secure the battery within the deadbolt.
6. The method of claim 1 , further comprising:
disposing the deadbolt within a bolt sleeve; and
disposing the bolt sleeve within a bolt housing.
7. The method of claim 6 , wherein the bolt housing includes an attachment mechanism configured to attach to the main housing.
8. The method of claim 1 , wherein the deadbolt includes an attachment mechanism configured to attach to a bolt carriage of the main housing, wherein the bolt carriage is configured to move the deadbolt along the path.
9. The method of claim 8 , wherein the bolt carriage includes an electrical connection to the deadbolt.
10. The method of claim 9 , wherein the electrical connection to the deadbolt is configured to direct an electric current from the battery to the main housing.
11. The method of claim 8 , wherein the attachment mechanism is configured to move the deadbolt along the path to lock and/or unlock the door.
12. The method of claim 1 , wherein the deadbolt is mechanically connected to the main chassis via a male detent connector secured into a female groove of a bolt carriage, and wherein the deadbolt is electrically connected to the main chassis via one or more pogo pins connected to electrical receiver elements of the bolt carriage.
13. The method of claim 12 , further comprising:
aligning the one or more pogo pins with the electrical receiver elements of the bolt carriage by inserting the one or more pogo pins into the male detent connector.
14. The method of claim 1 , wherein the main housing includes an actuator configured to retract the deadbolt to operate in an unlocked state, and configured to extend the deadbolt into a deadbolt slot in a locked state.
15. The method of claim 14 , wherein the actuator is powered by the energy storage device within the hollow inner region of the deadbolt.
16. The method of claim 1 , wherein the main housing includes an accelerometer configured to rotate along a non-linear path as the electromechanical lock transitions between an unlocked state and a locked state, wherein the accelerometer is configured to determine a gravity vector representing an inclination of the accelerometer along the non-linear path.
17. The method of claim 16 , wherein the accelerometer is powered by the energy storage device within the hollow inner region of the deadbolt.
18. A method comprising:
connecting an actuator to a deadbolt via an electrical and mechanical connection;
powering the actuator with a battery disposed within a hollow inner region of the deadbolt; and
locking and/or unlocking a door by advancing the actuator connected to the deadbolt.
19. The method of claim 18 , wherein the actuator is disposed within a main housing, the deadbolt travelling along a path to lock and/or unlock the door.
20. The method of claim 19 , wherein the deadbolt includes an attachment mechanism configured to attach to a bolt carriage of the main housing,
wherein the bolt carriage is configured to move the deadbolt along the path,
wherein the bolt carriage includes an electrical connection to the deadbolt, and wherein the electrical connection is configured to direct an electric current from the energy storage device to the main housing.
21. A method comprising:
connecting a main housing to a deadbolt via an electrical and mechanical connection, wherein the main housing is configured to extend the deadbolt along a path to lock and/or unlock a door;
disposing a hollow inner region in the deadbolt, wherein the hollow inner region is configured to receive a battery;
disposing the deadbolt within a bolt sleeve; and
disposing the bolt sleeve within a bolt housing, wherein the bolt housing includes an attachment mechanism configured to attach to the deadbolt and to the main housing,
wherein the attachment mechanism includes an electrical connection to the deadbolt and is configured to extend the deadbolt along the path to lock and/or unlock the door, and
wherein the electrical connection is configured to direct an electric current from the energy storage device to the main housing.
22. The method of claim 21 , wherein the main housing includes an accelerometer configured to rotate along a non-linear path as the deadbolt transitions between an unlocked state and a locked state, wherein the accelerometer is configured to determine a gravity vector representing an inclination of the accelerometer along the non-linear path,
wherein the accelerometer is powered by the energy storage device within the hollow inner region of the deadbolt.
