Electric automobile wireless charging device with position of receiving electromagnet assembly adjustable

Abstract

The invention relates to the field of electric automobiles, in particular to an electric automobile wireless charging device with the position of a receiving electromagnet assembly adjustable. The electric automobile wireless charging device comprises an electric energy receiving end arranged in the center of an automobile chassis and an electric energy transmitting end arranged in the center of a parking place and under the ground and is characterized in that the electric energy receiving end comprises the receiving electromagnet assembly, an X-axis motor for controlling the receiving electromagnet assembly to horizontally move leftwards and rightwards, a Y-axis motor for controlling the receiving electromagnet assembly to horizontally move forwards and backwards and a Z-axis motor for controlling the receiving electromagnet assembly to be displaced upwards and downwards; the electric energy transmitting end comprises a transmitting electromagnet assembly; and the receiving electromagnet assembly and the transmitting electromagnet assembly are opposite in a spaced manner. Compared with the prior art, the electric automobile wireless charging device has the beneficial effects of being small in work amount, easy to implement, intelligent and user-friendly, time is saved, and the charging efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a wireless charging device for electric vehicles with an adjustable receiving electromagnet assembly, so as to realize efficient charging of electric vehicles. Background technique [0002] The development of electric vehicles is an effective strategy recognized by the world to alleviate energy shortage and environmental pollution, and it is very important to our country. Taking my country's oil consumption as an example, the net import of oil in 2009 was about 204 million tons, and the import dependence reached 52%, far exceeding the international warning line of 35%. Among them, vehicle fuel consumption accounts for 1 / 3 of the total oil consumption. Therefore, the development and promotion of automobile alternative fuels and electric vehicles, and the reduction of fuel consumption are of great strategic significance for mitigating environmental pollution in my country, ensurin...
