Wireless charging system for charging shared power bank by charging cabinet

Abstract

The invention discloses a wireless charging system for charging a shared power bank by a charging cabinet. The wireless charging system comprises a transmitting end and a receiving end; the transmitting end comprises a PD decoy module, a voltage reduction module, an STM32 main control module, a driving module, a full-bridge module and an LC oscillation module; the transmitting end is connected with 220V commercial power; the commercial power is processed to 12V, then the commercial power is reduced to 3.3 V and 5V, and the final commercial power is supplied to the STM32 main control module, the driving module and the full-bridge module; the driving module controls and drives the full-bridge module to be switched on; and the full-bridge module converts direct current into alternating current and outputs the alternating current to the LC oscillation module; and the receiving end comprises a resonance module, a rectification module and a voltage regulation module; the receiving end obtains the induced electromotive force from the transmitting end, rectifies the induced electromotive force to obtain direct current, adjusts the direct current to charging voltage and outputs the charging voltage to charge a storage battery of the power bank. The system is low in cost, stable and reliable in performance and high in continuous charging efficiency and fully ensures the charging effect; and a good guarantee is well provided for popularization of the wireless charging technology in the aspect of shared power banks.

Description

technical field [0001] The invention relates to the technical field of shared charging treasures, in particular to a wireless charging system for realizing the charging of a shared charging treasure by a charging cabinet. Background technique [0002] With the continuous development and progress of social science and technology, many market management models have also been developed in a blowout style. For example, the sharing model includes a variety of products such as shared bicycles, shared battery cars, shared electric vehicles, and shared charging treasures. , and has gradually become one of the important public resources, deeply integrated into the lives of the people. [0003] Taking shared charging treasures as an example, the shared charging treasure rental facilities placed in existing public places (such as tourist attractions, large shopping malls, airports, railway stations, etc.) adopt the method of concentrating the charging treasures in the charging treasure...
