Embodiment Construction
[0031] The invention provides a wireless charging device, system and method based on the back cover of a mobile power supply. Based on the wireless charging (electromagnetic induction mode) technology of an intelligent terminal, a one-to-many charging scheme is realized by using a power switching module, which can simultaneously charge intelligent The main battery of the terminal and the back cover of the mobile power supply can be charged efficiently and safely. When charging is not enabled, the back cover of the mobile power supply can supply power to the main power supply. In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The invention discloses a wireless charging device, system and method based on a rear cover of a mobile power supply. The wireless charging system comprises a wireless charger, the rear cover of the mobile power supply and an intelligent terminal, wherein a main battery and a wireless charging device are arranged in the intelligent terminal; when the wireless charger is connected with the power supply, a built-in induction coil is electrified and generates an electromagnetic field; the rear cover of the mobile power supply induces the electromagnetic field and generates current to the wireless charging device; when the wireless charging device detects the current, the intelligent terminal and the rear cover of the mobile power supply are controlled to enter a charging state and charging current is separately transmitted to the main battery of the intelligent terminal and the rear cover of the mobile power supply for charging, so that the intelligent terminal and the rear cover of the mobile power supply can be simultaneously charged when wireless charging is carried out, and the charging efficiency is improved. The problem that the intelligent terminal cannot be charged while the rear cover of the mobile power supply is charged in the prior art and the charging efficiency is low is solved.
Description
technical field [0001] The present invention relates to the technical field of charging, in particular to a wireless charging device, system and method based on a mobile power back cover. Background technique [0002] Wireless charging technology (electromagnetic induction method) is becoming more and more mature, and will be the mainstream charging method for smart terminals in the future. At present, there is a mobile power back cover (take a mobile phone as an example, the appearance is similar to the back cover of a mobile phone, and an output current interface is usually set at the bottom), which has a built-in back clip battery and a control circuit, and the mobile power back cover is covered on the smart terminal. On the back, the output current interface is directly plugged into the USB interface at the bottom of the smart terminal. Press the power switch on the back cover of the mobile power supply to control whether to charge the smart terminal. No need to use a da...
