Abstract
(EN)
A wireless charging apparatus, device, system, and method. The wireless charging device comprises: a transmitting coil (10); a first communication unit (20), configured to receive relative position information of a receiving coil (51) of a device to be charged; a plurality of prompting units (40), the plurality of prompting units (40) being arranged around the transmitting coil (10); and a control unit (30), configured to generate a trigger command of the prompting units (40) on the basis of the relative position information combined with the relative position relationship of the prompting units (40) and the transmitting coil (10) to control a prompting unit (40) in a corresponding position to turn on in order to indicate a placement position of the device to be charged, such that the transmitting coil (10) and the receiving coil (51) are aligned. The present wireless charging apparatus, device, system, and method can, to a certain extent, solve the problem of wireless charging coil alignment.

L'invention concerne un appareil, un dispositif, un système et un procédé de charge sans fil. Le dispositif de charge sans fil comprend : une bobine de transmission (10) ; une première unité de communication (20), conçue pour recevoir des informations de position relative d'une bobine de réception (51) d'un dispositif à charger ; une pluralité d'unités d'invite (40), la pluralité d'unités d'invite (40) étant agencées autour de la bobine de transmission (10) ; et une unité de commande (30), configurée pour générer une instruction de déclenchement des unités d'invite (40) sur la base des informations de position relative combinées à la relation de position relative des unités d'invite (40) et de la bobine de transmission (10) pour commander une unité d'invite (40) dans une position correspondante afin qu'elle tourne pour indiquer une position de placement du dispositif à charger, de telle sorte que la bobine de transmission (10) et la bobine de réception (51) soient alignées. L'appareil, le dispositif, le système et le procédé de charge sans fil selon l'invention peuvent, dans une certaine mesure, résoudre le problème de l'alignement de la bobine de charge sans fil.
