Bluetooth headset charging box and its charging method

Abstract

The invention provides a Bluetooth headset charging box and a charging method thereof. Through a first connector, a second connector, a charging control unit, a battery and a wireless electric power receiving unit used for receiving and converting a wireless electric power signal, a wired charging mode is realized when an external wired power input is available, a wireless charging mode is realized when wireless electric power signal transmission is available, and a battery charging mode is also realized when both the external wired power input and the wireless electric power signal transmission are unavailable; the wireless charging mode realizes that electric power can be received under the circumstance that no physical power cords are used, and cannot be limited by the socket position of the mains supply, an external connecting cable and the plugging-unplugging actions are completely omitted, and the charging process is enabled to be simpler and more convenient.

Description

technical field [0001] The invention relates to the technical field of charging devices, in particular to a Bluetooth earphone charging box and a charging method thereof. Background technique [0002] Bluetooth technology is a cutting-edge open wireless communication technology launched in 1998, and then the Bluetooth Technology Special Interest Group (SIG, Special Interest Group) was established, which is responsible for the development of Bluetooth technology and the formulation of technical protocols. Bluetooth technology can wirelessly connect computers, notebook computers, personal digital assistants (PDA, Personal Digital Assistant), mobile phones, digital cameras and other portable mobile terminals within a short distance, so that various mobile terminals can communicate wirelessly, making short-distance Data transfer is more convenient and faster. [0003] An important application of Bluetooth technology is Bluetooth headsets. The main advantage of Bluetooth headse...

Problems solved by technology

[0004] However, the bluetooth earphones in the prior art have at least the following defects: the common chargers used in the prior art bluetooth earphones are all to charge the bluetooth earphones after the mains voltage has been transformed and stabilized. Bluetooth earphones cannot be charged in other places; Bluetooth earphones generally use a built-in battery, which cannot be replaced at any time like a mobile terminal, and the battery capacity of a Bluetooth earphone is relatively small, and it usually requires frequent charging when the frequency of use is high, and the charging time is relatively short. Long, so the use of Bluetooth headsets is subject to certain restrictions; in addition, some Bluetooth headsets are equipped with a special charging box, the charging box has a built-in battery, which can not only be used as a mobile power supply to charge the Bluetooth headset, but also protect and store the Bluetooth headset. Function, at present, this kind of charging box generally needs an external power cord to take the mains to charge itself and the Bluetooth headset it contains. It can be seen that it is also impossible to charge itself in places where there is no mains socket
