POWER-ASSISTING DEVICE AND A POWER-ASSISTED ELECTRIC WHEELCHAIR, CAPABLE OF ACCURATELY JUDGING A DRIVING WILL AND HAVING LOW MANUFACTURING COSTS

摘要

PURPOSE: A power-assisting device and a power-assisted electric wheelchair are provided to accurately judge a driving will with regard to force applied by a user, thereby enabling a user to exercise for reinforcing upper muscles.;CONSTITUTION: A power-assisting device(2) comprises handrims(20L,20R) which are rotatably coupled to the wheel from the outer side of the wheelchair main body; sensor modules(30L,30R) which measure force of a user when the user applies force to the handrims and transfer the force toward the wheel; a control module(40) which outputs a motor control signal corresponding to the force of the user measured by the sensor modules; and motors(50L,50R) which rotate the wheel of the wheelchair main body by being operated by the motor control signal output from the control module.;COPYRIGHT KIPO 2013;[Reference numerals] (20L) Hand-rim L; (20R) Hand-rim R; (30L) Sensor module L; (30R) Sensor module R; (34L) FSR sensor L; (34R) FSR sensor R; (35L) AD converter L; (35R) AD converter R; (36L) First communication unit L; (36R) First communication unit R; (40) Control module; (41) Second communication unit; (42) Acceleration determination unit; (43) Wheel speed conversion unit; (44L) Motor control unit L; (44R) Motor control unit R; (50L) Motor L; (50R) Motor R; (60) Power supply unit
