INTELLIGENT POWER WIRELESS CHARGING SYSTEM FOR ELECTRIC WHEELCHAIRS, ROBOTIC ARM AND RANGING SENSOR THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/156523
Kind Code:
A1
Abstract:
An intelligent power wireless charging system for electric wheelchairs, comprises: a wireless charging transmitter, the transmitter has a transmitter and a robotic arm with a transmitter pad; a wireless charging receiver installed in the electric wheelchair; when the electric wheelchair is driven to the transmitter within a certain area, the transmitter receives the signal from the wireless charging receiver, a laser sensor of the transmitter detects the position of the electric wheelchair, a laser sensor of the transmitter emits reference lines for guiding the electric wheelchair is parked within the predefined charging parking area; the robotic arm is activated and carries the transmitter pad from the standby position to move to the predefined waiting for charging position; the laser sensor of the transmitter pad is activated and detects the position of the electric wheelchair, the robotic arm automatically find the wireless charging receiver to charge; when the charging is completed, the robotic arm automatically returns to the standby position.
