Embodiment Construction

[0028] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] figure 1 It is a structural schematic diagram of the magnetic coupling mechanism of the present invention, such as figure 1 As shown, a secondary winding 1, 2 is respectively wound on a secondary U-shaped iron core 3, 4, and the magnetic fluid 5 is affixed to both ends of the primary U-shaped iron core through a container 6. When a secondary winding 1 , When there is power exchange between 2, the magnetic fluid connects the two ends of the primary and secondary U-shaped iron cores 3 and 4 due to its magnetic properties and fluidity, thus greatly improving the energy transmission efficiency and transmission capacity in the device .

[0030] At the same time, the iron core material of the primary and secondary sides of the present invention is an amorphous nanocrystalline alloy, which has the same shape and size, and is obtained by s...

Abstract

The invention relates to a magnetic coupling mechanism based on magnetic fluid and an electric bus wireless charging system, and relates to the field of energy transmission and wireless charging. Themagnetic coupling mechanism comprises a primary side U-shaped core and a secondary side U-shaped core which are symmetrically arranged; the secondary side U-shaped core is arranged in an electric bus,a secondary side coil is wound around the secondary side U-shaped core, and the secondary side coil is used for charging a battery pack of the electric bus; the primary side U-shaped core is arrangedoutside the electric bus and used for being coupled with the secondary side U-shaped core, and a primary side coil is wound around the primary side U-shaped core and used for conducting power exchange with the secondary side coil; two magnetic fluid devices are arranged between the primary side U-shaped core and the secondary side U-shaped core, and when the primary side U-shaped core and the secondary side U-shaped core conduct energy transmission through magnetic coupling, flexible connection of both ends of the primary side U-shaped core and the secondary side U-shaped core is achieved through the magnetic fluid. The magnetic coupling mechanism based on the magnetic fluid and the electric bus wireless charging system have the advantages that in the condition that the number of turns and electric current of the primary side coil are not changed, a larger magnetic flux density is generated, and the magnetic coupling efficiency is improved on a large scale.

Description

technical field [0001] The invention relates to the fields of energy transmission and wireless charging, and relates to a magnetic coupling mechanism based on magnetic liquid and a wireless charging system for an electric bus. Background technique [0002] In the field of wireless energy transmission, large energy capacity and high-efficiency fast transmission have always been the pursuit goals of scientific researchers. Today's wireless energy transfer methods mainly include inductive coupling, magnetic resonance, electric field induction, microwave and laser. The electric field induction transmission method has a large radiation to the human body, and the application field is limited; microwaves and lasers are suitable for long-distance energy transmission, because the long-distance transmission of electromagnetic waves in the air will be greatly attenuated, so the transmission capacity is limited; due to induction Coupled and magnetic resonance wireless energy transfer m...
