Abstract

A paved structure capable of feeding power to a traveling body in a noncontact manner. The paved structure feeding power to a power receiver provided in a traveling body through an electromagnetic wave, includes: a depression extending in the direction in which the traveling body runs; a magnetic member laid in the depression; a power feeding body laid on the upper surface of the magnetic member to feed power to the power receiver through an electromagnetic wave; and a power feeding body protector laid in the depression to cover the power feeding body.

Claims

1. A paved structure feeding power to a power receiver provided in a traveling body through an electromagnetic wave, comprising:

a depression extending in the direction in which the traveling body runs;

a magnetic member laid in the depression so that a flat upper surface is formed;

a power feeding body laid on the upper surface of the magnetic member to feed power to the power receiver through an electromagnetic wave; and

a power feeding body protector laid in the depression to cover the power feeding body, and

a reinforcement that is a mesh net having a predetermined constant width and a constant length laid in the depression, wherein the power feeding body is coiled and attached to the net.

2. The paved structure according to claim 1, wherein an electromagnetic wave shield is concaved on the inner surface of the depression, and the magnetic member is laid in the concave of the electromagnetic wave shield.

3. The paved structure according to claim 2, wherein the electromagnetic wave shield has a partition in the center of the depression to form two grooves in the depression, and the power feeding body is laid in each of the two grooves.

4. The paved structure according to claim 2, wherein the electromagnetic wave shield is formed from a stainless panel or net, an aluminum panel or net, or combination thereof.

5. The paved structure according to claim 1, wherein the power feeding body protector is the same magnetic body as or a different magnetic body from the magnetic member.

6. The paved structure according to claim 1, wherein the magnetic member contains magnetic slag.

7. The paved structure according to claim 1, further comprising:

a visible part visible from the traveling body, wherein

the visible part is provided on the upper surface of the power feeding body protector over the power feeding body.

8. The paved structure according to claim 7, wherein the visible part is colored in a color different from that of the power feeding body protector.

9. The paved structure according to claim 7, wherein the visible part is formed of a retro reflective material.

10. A method of constructing the paved structure according to claim 1, comprising the steps of:

forming a depression in the paved structure;

laying a magnetic member in the depression; and

laying a power feeding body on the magnetic member.
