Abstract

The invention discloses a rehabilitation wheel chair. The rehabilitation wheel chair comprises a wheel chair body and a pedal device arranged on the wheel chair body. The pedal device comprises pedalplates, a transmission box and cranks. The transmission box is provided with a chair force feedback device. One end of each crank is connected with a pedal shaft of the corresponding pedal plate, andthe other end of each crank is connected with a transmission shaft of the transmission box. The chair force feedback device comprises a motor and a linkage device, the motor is provided with an outputshaft, and the linkage device is in linkage with the output shaft. A strain sensing device electrically connected with a controller is arranged on the linkage device. The controller converts stress signals of the strain sensing device into torque signals. The rehabilitation wheel chair has the advantages that the pedal device is provided with the chair force feedback device, the strain sensing device is arranged on the linkage device which is in linkage with the motor in the chair force feedback device, and the technical effect of accurate torque measurement is realized, so that the problem that rehabilitation wheel chairs in related technologies cannot be used for refined rehabilitation training due to nonexistence of an integrated torque feedback device is solved.

Description

technical field [0001] The invention relates to the field of rehabilitation equipment, in particular to a rehabilitation wheelchair. Background technique [0002] Rehabilitation wheelchair is a kind of equipment used for rehabilitation training of the elderly and physically handicapped patients. Its characteristic is that the output shaft drives the crank to rotate. Purpose. At present, the rehabilitation wheelchairs on the market are relatively simple in structure. The motor directly drives the output shaft to rotate. There is no integrated force or torque sensor inside. Since there is no force or torque feedback, this kind of rehabilitation wheelchair cannot be used for refined rehabilitation. train. [0003] Therefore, there is an urgent need for a rehabilitation wheelchair to solve the problem that the rehabilitation wheelchair in the related art does not have an integrated torque feedback device and cannot be used for refined rehabilitation training. Contents of the ...
