Abstract
An NFC watch includes a metal shell, a support and an NFC antenna arranged at the top of the support, wherein the support is mounted at the bottom of the metal shell, and the NFC antenna is clamped between the metal shell and the support and exposed to the outside. The NFC watch further includes a PCB arranged in the support and electrically connected with the NFC antenna and a power supply arranged at the bottom of the support and used for supplying power to the PCB. The NFC watch is simple in structure and high in practicability.
Claims8
A NFC watch with a deactivatable and activatable NFC functionality and/or a controllable NFC transmission power, comprising:
- a metal shell, a support arranged in the metal shell and a switchable an NFC antenna is arranged at the top of the support disposed for controlling the NFC transmission power, wherein the support is mounted at the bottom of the metal shell, and the NFC antenna is clamped between the metal shell and the support and exposed to the outside of the support disposed for weakening eddy current effect between the metal shell and the NFC antenna;
- the NFC watch further comprises a PCB arranged in the support and electrically connected with the NFC antenna and functioned independently from the NFC antenna and having a NFC chip being switchable in response to a working state of the NFC watch and a power supply arranged at the bottom of the support and used for supplying power to the PCB;
- wherein the NFC watch is configured to enable the NFC antenna to be switchable between an activated state and a deactivated state;
- wherein when the NFC antenna is activated in the activated state, the power supply is, preferably configured to provide a first power, adapted for enabling activation and normal operation for NFC functionality of the PCB and the NFC antenna is configured to increase the NFC transmission power and wireless communication distance of the NFC watch, and reduce interference to NFC communication and ensure communication quality;
- and
- when the NFC antenna is deactivated in the deactivated state, the power supply is, preferably configured to provide a second power being much lower than the first power and, adapted for enabling deactivation of NFC functionality and normal operation for non-NFC functionality of the PCB and the NFC antenna is configured to increase endurance of the NFC watch;
- and/or wherein the support is configured to enable the NFC antenna, the power supply and the PCB to be separated in the metal shell in such a manner that the NFC antenna and the power supply are arranged at opposite ends of the support and the PCB is arranged inside the support preferably to structurally reduce interference to the NFC antenna from the power supply and the PCB when NFC functionality of the PCB is activated, so as to optimize a radiation path of the NFC antenna.
