Problems solved by technology

However, the general wireless charging module needs to be aligned with the power transmitter to perform wireless charging. In addition, the use of wireless charging and NFC functions is limited to a very short distance. Therefore, it is suitable for small portable electronic devices such as electronic watches. The NFC function and wireless charging function of the device cannot fully realize its convenience of use

Abstract

A portable electronic device capable of extending near field communication distance comprises a watchband portion, a power supply module, an NFC module and a relay coil group arranged in the watchband portion. The power supply module comprises a wireless charging receiving coil, a charging circuit and a charging battery. The NFC module comprises an NFC antenna and an NFC circuit. The relay coil group receives external electromagnetic wave energy and transmits the external electromagnetic wave energy to the wireless charging receiving coil, so that the charging battery is charged through the charging circuit. The relay coil group also receives an external NFC read-write signal and forwards the external NFC read-write signal to the NFC antenna, or receives NFC data or an internal NFC read-write signal sent by the NFC antenna and forwards the NFC data and the internal NFC read-write signal to other electronic devices outside the electronic device. According to the electronic device in the invention, the transmission distance of signals is extended through the magnetic resonance between coils, and the positions of the coils do not need to be corresponding completely, so that positioning-free charging and NFC are realized, and the convenience and usage efficacy of wireless charging and NFC are improved.

Description

technical field [0001] The invention relates to the technical field of short-distance wireless communication, in particular to a portable electronic device capable of extending the distance of short-distance wireless communication. Background technique [0002] With the development of information technology, small, lightweight and powerful fashion consumer goods are more and more favored by consumers. At the same time, the watch industry has also undergone tremendous changes because of consumers' consumption concepts. As a result, there are more and more electronic watches with various functions, such as electronic notepad, GPS (Global Position System, global positioning system), MP3 (Moving Picture Experts Group Audio Layer III), Functions such as NFC (Near Field Communication, near-field communication technology) authentication are integrated into electronic watches to meet various needs of consumers. [0003] At the same time, electronic watches consume more and more ele...
