Detailed Description
The technical solution of the present invention will be further explained with reference to the following embodiments and accompanying drawings.
Example 1
The embodiment provides a wireless charging positioning device for an electric vehicle, which comprises a charging control cabinet and a lateral positioning assembly arranged on at least one side of a ground power supply device.
That is, in this embodiment, the lateral positioning assembly may be one and disposed at one side of the ground power supply device; or the number of the lateral positioning assemblies is two, and the two lateral positioning assemblies are respectively arranged on two sides of the ground power supply device.
The charging control cabinet is provided with a first distance sensor for detecting the distance between the head or the tail of the vehicle and the charging control cabinet, and whether the charging coil of the vehicle is aligned with the ground power supply device in the length direction of the vehicle is obtained through the distance and the size parameters of the vehicle.
The lateral positioning assembly comprises an upright column and a second distance sensor installed on the upright column, the second distance sensor is used for detecting the distance between the side portion of the vehicle and the upright column, and whether the charging coil of the vehicle is aligned with the ground power supply device in the width direction of the vehicle or not is obtained through the distance and the size parameters of the vehicle.
Furthermore, when the lateral positioning assemblies are two, the connection line between the two second distance sensors passes through the center of the coil of the ground power supply device.
The charging control cabinet comprises a controller and a communication module, wherein the communication module can be a WiFi module, namely the controller can be connected to an IVU (vehicle-mounted communication control unit) of a vehicle through the communication module, the first distance sensor and the second distance sensor are in signal connection with the controller and send data detected by the first distance sensor and the second distance sensor to the IVU, and the IVU obtains a coordinate difference between a charging coil and a ground power supply device of the vehicle according to parameters of the vehicle and displays the coordinate difference on a display device (such as a vehicle central control screen); and the driver continues to adjust the position and the posture of the vehicle according to the information to guide the charging requirement to be met.
