Abstract

The invention discloses a device capable of automatically adjusting the position of a transmitting coil, being applied to adjustment of the position of the transmitting coil in the wireless charging process of an electric vehicle. The device comprises a circumferential adjusting device, a distance adjusting device, a radial adjusting device and a horizontal adjusting device, wherein the circumferential adjusting device is used for adjusting the circumferential position; the distance adjusting device is used for adjusting the vertical distance between the transmitting coil and the charging coil; the radial adjusting device is used for adjusting the position in the radial direction; and the horizontal adjusting device is used for maintaining the horizontal position of the transmitting coil.The device capable of automatically adjusting the position of a transmitting coil can automatically adjust the position of the transmitting coil so as to increase the energy transfer efficiency between the transmitting coil and the receiving coil.

Description

technical field [0001] The invention relates to the field of wireless charging of electric vehicles, in particular to a device capable of automatically adjusting the position of a transmitting coil. Background technique [0002] In recent years, under the situation of energy and environmental crisis, electric vehicles are favored by the masses because they use electric energy as the power source and have no exhaust gas to be discharged. Electric vehicle wireless charging technology has also emerged with the development of the electric vehicle industry. In the actual operation of electric vehicle wireless charging, the positional relationship between the receiving coil and the transmitting coil generally does not change after the electric vehicle is parked, and the positional relationship between the receiving coil and the transmitting coil affects the energy transmission efficiency and charging requirements during the wireless charging process. important factor of duration....
