초록 ▼

An electronic key may include a partial capacitor comprising a capacitive metal plate in communication with a processor. The capacitive metal plate of the partial capacitor is configured to form a capacitor with a corresponding capacitive metal plate of a lock when brought into proximity with the metal plate of the lock. Data may be transferred from the key to the lock using a capacitor formed by combining the two metal plates, wherein a common ground is established between the metal plate of the key and the metal plate of the lock through a parasitic capacitance present between the key and lock circuitry.

대표청구항 ▼

1. An electronic key comprising: a housing;a processor within the housing; anda first capacitive metal plate in electrical communication with the processor, the first capacitive plate forming a capacitor when brought into proximity with a corresponding second capacitive metal plate of a lock, the first capacitive metal plate comprising a ring-shaped disc, the ring-shaped disc including a slit formed from an outer perimeter edge of the ring-shaped disc to an inner perimeter edge of the ring-shaped disc, the slit preventing a short from occurring within the first capacitive metal plate. 2. The electronic key of claim 1, wherein the first capacitive metal plate comprises a single electrical connection to the processor. 3. The electronic key of claim 1, wherein the slit breaks an electrical connection between one part of the first capacitive metal plate and another part of the first capacitive metal plate. 4. The electronic key of claim 1, further comprising a key nose assembly disposed within an inner area of the first capacitive metal plate, the inner area bounded by the inner perimeter edge of the ring-shaped disc. 5. The electronic key of claim 4, further comprising a key power coil that is concentric with the first capacitive metal plate and is disposed at least partially within the key nose assembly. 6. The electronic key of claim 5, wherein the key nose assembly further comprises a magnetic core, the key power coil wrapping around a portion of the magnetic core. 7. The electronic key of claim 1, wherein the first capacitive metal plate is configured to transfer data between the electronic key and the lock when brought into proximity with the corresponding second capacitive metal plate of the lock. 8. The electronic key of claim 1, wherein the first capacitive metal plate further comprises a tab connector that is in electrical communication with the processor. 9. The electronic key of claim 1, wherein the first capacitive metal plate is in electrical communication with a common reference point provided by a key power coil. 10. An electronic lock comprising: a housing;a flexible circuit board within the housing;a first capacitive metal plate in electrical communication with the flexible circuit board, the first capacitive plate forming a capacitor when brought into proximity with a corresponding second capacitive metal plate of an electronic key, the first capacitive metal plate comprising a ring-shaped disc, the ring-shaped disc including a slit formed from an outer perimeter edge of the ring-shaped disc to an inner perimeter edge of the ring-shaped disc, the slit reducing the occurrence of eddy currents within the first capacitive metal plate. 11. The electronic lock of claim 10, wherein the first capacitive metal plate comprises a single electrical connection to the flexible circuit board. 12. The electronic lock of claim 10, wherein the slit breaks an electrical connection between one part of the first capacitive metal plate and another part of the first capacitive metal plate. 13. The electronic lock of claim 10, further comprising a lock cup assembly configured to receive a key nose assembly of the electronic key, the first capacitive metal plate positioned around a perimeter of an opening of the lock cup assembly configured to receive the key nose assembly. 14. The electronic lock of claim 13, wherein the lock cup assembly further comprises a cup formed from the housing and a magnetic core positioned beneath a base of the cup formed from the housing. 15. The electronic lock of claim 14, wherein the cup of the lock cup assembly is at least partially surrounded by a power coil and wherein at least one of the magnetic core or the power coil is at least partially surrounded by a mu-metal layer. 16. The electronic lock of claim 13, further comprising a power source, the power source configured to recharge a key power source of the electronic key when the key nose assembly of the electronic key is positioned within the lock cup assembly of the electronic lock. 17. The electronic lock of claim 10, further comprising a lock assembly within the housing, the lock assembly comprising a coil assembly for locking and unlocking the electronic lock. 18. The electronic lock of claim 17, wherein the flexible circuit board is at least partially wrapped around the coil assembly. 19. The electronic lock of claim 10, wherein the first capacitive metal plate further comprises a tab connector that is in electrical communication with the flexible circuit board. 20. The electronic lock of claim 10, wherein the first capacitive metal plate is configured to transfer data between the electronic lock and the electronic key when the corresponding second capacitive metal plate of the electronic key is brought into proximity with the first capacitive metal plate.
