The invention discloses a vehicle-mounted wireless charging system which comprises a ground transmitting end device and a vehicle receiving end device. The receiving end device is fixed below a vehicle chassis and comprises a secondary circuit, a receiving end controller and a power receiving coil; the ground transmitting end device comprises a main-stage circuit, a transmitting end controller, apower supply coil and a distance measuring device, the ground transmitting end device comprises a fixed bottom and a movable upper part, the fixed bottom is fixed on the ground, and the movable upperpart comprises a rotating mechanism and a telescopic mechanism; and the rotating mechanism and the telescopic mechanism are electrically connected with the sending end controller, and the distance measuring device is used for detecting the position of the receiving end device and calculating the distance between the receiving end device and the ground sending end device. According to the invention, the requirement for the accuracy of an automatic parking system or manual parking of a driver is lowered, the situations that the wireless charging efficiency is low and even charging cannot be performed due to inaccurate parking positions are reduced, and the vehicle-mounted wireless charging efficiency is improved.

    本发明公开了一种车载无线充电系统,包括地面发送端装置和车辆接收端装置,所述接收端装置固定于车辆底盘下方,所述接收端装置包括次级电路、接收端控制器和受电线圈,所述地面发送端装置包括主级电路、发送端控制器、供电线圈及测距装置,所述地面发送端装置包括固定底部和活动上部,所述固定底部固定于地面,所述活动上部包括一旋转机构和一伸缩机构,所述旋转机构和伸缩机构与发送端控制器电连接,所述测距装置用于检测接收端装置的位置,计算接收端装置与地面发送端装置的距离。降低了对自动泊车系统或驾驶员人工泊车精准度的要求,减少了因泊车位置不精准造成的无线充电效率低甚至未能充电情况的发生,提高了车载无线充电效率。
