The invention relates to a near field communication and wireless charging device and a near field communication and wireless charging switching method. The near field communication and wireless charging device comprises a coil, a frequency modulation module, a near field communication module, a wireless charging module and an electricity storage device, and is characterized in that the coil is used for receiving an electromagnetic wave; the frequency modulation module is electrically connected to the coil; the near field communication module comprises an attenuator and a near field communication control circuit; the attenuator is used for attenuating energy of the electromagnetic wave transmitted from the frequency modulation module; the near field communication control circuit is electrically connected to the attenuator; the electricity storage device is electrically connected to the wireless charging module; and the electromagnetic wave can perform magnetic coupling with the coil, a signal of the electromagnetic wave is transmitted to the near field communication module through the frequency modulation module by the aid of the coil, or the energy of the electromagnetic wave is transmitted to the electricity storage device through the frequency modulation module and the wireless charging module. The near field communication and wireless charging device can achieve functions of near field communication and wireless charging through the single coil, so that the overall thickness and the complexity in design of the near field communication and wireless charging device can be significantly reduced.
Description
technical field [0001] The invention relates to a near field communication and wireless charging device. Background technique [0002] With the development of wireless transmission technology, more and more portable (such as handheld or wearable) electronic products have the function of wireless transmission. Wireless transmission technology replaces traditional connecting wires, and transmits and receives electromagnetic waves through antennas, allowing electronic products to transmit signals or energy without physical contact with the transmission source. [0003] Among them, the wireless charging (Wireless Charging) technology and the near field communication (Near Field Communication) technology are both the main wireless transmission technologies at present, and basically require their own antennas to send and receive electromagnetic waves. Wireless charging is to receive electromagnetic waves to achieve the charging effect, while near-field communication transmits and...
