Document Type and Number:
WIPO Patent Application WO/2021/230587
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a contactless power supply and data communication apparatus and a rotationally driven lidar system which applies the contactless power supply and data communication apparatus. The apparatus comprises: a main shaft which connects and fixes an upper assembly at the center while being supported by a lower assembly of a body housing; a motor which provides rotational power for rotating a rotating part about the main shaft; a wireless power unit which consists of a transmitting unit core bound and fixed to the outer circumferential surface of the main shaft and a receiving unit core rotating at an upper end spaced apart from the transmitting unit core, so as to supply and receive power by means of electromagnetic induction; and an optical communication unit in which a rotating communication device provided on a rotating substrate formed on the top thereof and rotating about the main shaft and a fixed communication device provided on a fixed substrate fixed to the bottom thereof are spaced apart from each other at a predetermined distance, so as to transmit and receive an optical signal.
