Abstract

The embodiment of the invention discloses a wireless charging receiving module and a wireless charging system. The wireless charging receiving module comprises a receiving antenna, an impedance matching unit, a rectifying unit and a power management unit. The receiving antenna is used for receiving electromagnetic wave signals. The impedance matching unit is electrically connected with the receiving antenna and used for carrying out impedance matching to make the electromagnetic wave signals transmitted at the maximum power. The rectifying unit is electrically connected with the impedance matching unit and used for converting the electromagnetic wave signals into DC signals. The power management unit is electrically connected with the rectifying unit and used for amplifying the DC signalsfor loads. By means of the technical scheme, the problems that an existing wearable device is limited in wireless charging distance and the charging position is limited can be solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless charging, and in particular to a wireless charging receiving module and a wireless charging system. Background technique [0002] Existing wearable devices are favored by more and more users because of their powerful functions. For wearable devices, the biggest challenge is how to properly and conveniently supply them with continuous power, and for many current wristband and watch designs, users must first take them off and plug them into wired chargers. Charging, charging is more troublesome. [0003] In order to solve the above problems, many products adopt an electromagnetic induction charging scheme. This solution utilizes resonant coils to conduct electrical energy. Specifically, a sending coil is set in the charger, and a receiving coil is set on the wearable device. By applying a changing current to the sending coil to generate a change in the electromagnetic field...
