Abstract

The invention relates to an energy emission end of a multi protruded type magnetic coupling mechanism applied to wireless power supply of electromobile, belongs to the technical field of wireless energy transmission, and aims at solving the problems that there is no gap among magnetic cores of a present wireless power supply device of the electromobile, structure adjustment is inconvenient, and the using amount of magnetic cores is large. N magnetic poles are arranged successively along the length direction, and the distance between adjacent magnetic poles is q; each magnetic pole comprises at least one protruded magnetic core, two adjacent magnetic poles include at least three protruded magnetic cores, all protruded magnetic cores in one magnetic pole are arranged successively along the length direction, and the distance between adjacent protruded magnetic cores is d; each protruded magnetic core is composed of a long-strip-shaped bottom magnetic core part and a long-strip-shaped vertical magnetic core part, and the protruded magnetic core includes homocentric squares in the downward view; and a power supply cable is wound around all the long-strip-shaped vertical magnetic core part of each magnetic pole sequentially. The energy emission end is applied to wireless power supply of the electromobile.

Description

technical field [0001] The invention relates to an energy transmitting end of a multi-convex magnetic coupling mechanism applied to electric vehicle wireless power supply, and belongs to the technical field of wireless energy transmission. Background technique [0002] With the prominent environmental problems and energy pressure, the promotion of electric vehicles has been favored by countries all over the world. Compared with traditional plug-in charging technology, electric vehicle wireless charging technology has better security and flexibility, and its application prospect is very broad. Among them, dynamic wireless charging technology can effectively increase the cruising range of electric vehicles and reduce the number of battery packs, which not only reduces the cost of electric vehicles, but also prolongs their service life, making power supply safer and more reliable. [0003] At present, track-type wireless power supply equipment with a magnetic core structure ca...
