Title
(EN) WIRELESS CHARGING SYSTEM AND WIRELESS CHARGING METHOD
(FR) SYSTÈME DE CHARGE SANS FIL ET PROCÉDÉ DE CHARGE SANS FIL
(ZH) 一种无线充电系统和无线充电方法
Abstract
(EN) A wireless charging system and a wireless charging method. The wireless charging system comprises a first electronic device (2100), a wireless charging device (2200) and a second electronic device (2300), wherein the wireless charging device is located between the first electronic device and the second electronic device; the wireless charging device is an accessory device of the first electronic device and is physically connected to the first electronic device; the wireless charging device comprises a receiving circuit and a housing; the receiving circuit comprises a receiving coil, and the receiving coil is located on the inner side of the housing; and the first electronic device is used for charging the wireless charging device, charging the second electronic device by means of the wireless charging device, and receiving electric energy from the second electronic device by means of the wireless charging device. The wireless charging system and the wireless charging method solve the problem of a poor user experience due to the fact that a smart accessory needs to be removed when a wireless charging transmitting end device or receiving end device is changed.
(FR) La présente invention concerne un système de charge sans fil et procédé de charge sans fil. Le système de charge sans fil comprend un premier dispositif électronique (2100), un dispositif de charge sans fil (2200) et un second dispositif électronique (2300), le dispositif de charge sans fil étant situé entre le premier dispositif électronique et le second dispositif électronique ; le dispositif de charge sans fil étant un dispositif accessoire du premier dispositif électronique et étant physiquement connecté au premier dispositif électronique ; le dispositif de charge sans fil comprenant un circuit de réception et un boîtier ; le circuit de réception comprenant une bobine de réception, et la bobine de réception étant située sur le côté interne du boîtier ; et le premier dispositif électronique étant utilisé pour charger le dispositif de charge sans fil, charger le second dispositif électronique au moyen du dispositif de charge sans fil, et recevoir de l'énergie électrique provenant du second dispositif électronique au moyen du dispositif de charge sans fil. Le système de charge sans fil et le procédé de charge sans fil résolvent le problème d'une mauvaise expérience d'utilisateur due au fait qu'un accessoire intelligent doit être retiré lorsqu'un dispositif d'extrémité de transmission de charge sans fil ou un dispositif d'extrémité de réception est changé.
(ZH) 一种无线充电系统和无线充电方法,该无线充电系统包括第一电子设备(2100)、无线充电设备(2200)和第二电子设备(2300),无线充电设备位于第一电子设备和第二电子设备之间,其中,无线充电设备为第一电子设备的附属设备且与第一电子设备物理连接,无线充电设备包括接收电路和外壳,接收电路包括接收线圈,接收线圈位于外壳的内侧;第一电子设备用于对无线充电设备充电,用于透过无线充电设备对第二电子设备充电,以及用于透过无线充电设备接收来自第二电子设备的电能。该无线充电系统和无线充电方法解决了在更换无线充电发射端设备或接收端设备时,需要摘除智能配件,导致用户体验不佳的问题。
