Title:
COIL MEMBER, CONTACTLESS-TYPE POWER TRANSMISSION DEVICE, ELECTROMAGNETIC WAVE IRRADIATION/RECEPTION DEVICE, POWER TRANSMISSION/INFORMATION COMMUNICATION DEVICE, AND AUTONOMOUS MOBILE ROBOT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/225209
Kind Code:
A1
Abstract:
A first disclosure is a coil member (C) characterized in that a lead wire is wound in oval shape, with an oval shape cross section being curved along a major-axis direction of the oval shape cross section and having a curvature axis in a direction parallel to a minor-axis direction of the oval shape cross section. A second disclosure is a contactless-type power transmission device (P3) characterized by being provided with: a coil member (C) as a first coil (31); a second coil (32); and a tilting shaft (33) that makes variable, by means of the curvature axis as a rotating axis, an inclination between a central axis of the first coil (31), which is a rotational symmetric axis of the first coil (31), and a central axis of the second coil (32).
