Title:
MAGNETIC FIELD SCREENING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/141342
Kind Code:
A1
Abstract:
The present invention relates to a magnetic field screening device, and provided is a magnetic field screening device for a non-contact magnetic induction charging type electric car having mounted on the lower portion of a car body, a current collecting device for generating an organic electric power through the magnetic field of a power feeding device buried in a power feeding road, the magnetic field screening device comprising: actuators each placed on car body frames on both sides of the electric car, and equipped with a piston for moving vertically up and down according to pneumatics or hydraulics; and a screening member, which is connected to the piston of each of the actuators and moves up and down, has a structure of a plurality of screening plates made of a metallic material, separated from each other and laminated, so that when moving downwards, both sides of the current collecting device of the electric car are screened and an electromagnetic wave and the magnetic field generated between the current collecting device and the power feeding road are blocked from leaking outside.
