Abstract

The invention provides a box-type power supply rail applied to wireless power supply of mobile transportation equipment and power supply rail-based rail equipment, belongs to the technical field of magnetic coupling resonant wireless power transmission, and achieves the target of improving the performance of a system in achievement of wireless power supply for the mobile transportation equipment. The bottom parts of n magnetic poles all are fixed on a magnetic core; a power supply cable is wound along the outer surfaces of the magnetic poles, is wound to the middle position of the first magnetic pole from bottom to top along the outer surface of the first magnetic pole, further wound to the middle position of the second magnetic pole from bottom to top along the outer surface of the second magnetic pole, and so on; the power supply cable is wound to the top end of the nth magnetic pole from bottom to top along the outer surface of the nth magnetic pole, returns to the middle position of the outer surface of the (n-1)th magnetic pole to be wound to the bottom end from top to bottom until the power supply cable is wound on the outer surfaces of all magnetic poles; and the winding modes of the power supply cables on two adjacent magnetic poles are opposite. The box-type power supply rail is suitable for wireless power supply of electric vehicles.

Description

Technical field [0001] The invention belongs to the technical field of magnetic coupling resonance type wireless power transmission. Background technique [0002] With the increasing awareness of low-carbon environmental protection and green energy conservation, more and more mobile transportation equipment uses electric energy as their power source. Common power supply methods include sliding contact, cable drag chain and battery-powered. Among them, the sliding contact method has low safety and reliability and high maintenance cost. The cable drag chain type has strict restrictions on the moving distance, and the use environment is very limited. In occasions that require high equipment flexibility, battery power is usually used. There are two shortcomings of battery power supply. One is the size, weight, price, material, safety, charging speed, and life of the battery. The production process of the battery is highly polluting, consuming resources, and destroying the ecological...
