The charging device performs wireless charging.
但目前这种电磁感应式的无线充电方式都存在一个缺陷，需要将发射线圈与接收线圈对准，才能实现高效的无线充电过程，当发射线圈与接收线圈稍有偏差，就会造成电能传输效率的大幅度下降，而当使用者对充电设备进行充电时，很难将接收线圈与发射线圈对准，需要花费不少时间将待充电设备放置在无线充电装置的指定位置，不仅给使用者带来了诸多不便，而且也无法将发射线圈与接收线圈对准，从而使得充电效率无法提高。However, the current electromagnetic induction wireless charging method has a defect. It is necessary to align the transmitting coil and the receiving coil to achieve an efficient wireless charging process. When the transmitting coil and the receiving coil are slightly deviated, the power transmission efficiency will be caused. When the user is charging the charging device, it is difficult to align the receiving coil with the transmitting coil. It takes a lot of time to place the device to be charged in the designated position of the wireless charging device, which not only brings the user There is a lot of inconvenience, and it is impossible to align the transmitting coil with the receiving coil, so that the charging efficiency cannot be improved.
为此，急需一种宽范围接触感应的无线充电装置，自动识别接收线圈位置，最后使得使用者可以方便的将接收线圈与发射线圈对准，提高无线充电效率。Therefore, there is an urgent need for a wide-range contact induction wireless charging device that automatically recognizes the position of the receiving coil, and finally allows the user to conveniently align the receiving coil with the transmitting coil, thereby improving the efficiency of wireless charging.
