With the aging of the population problem is becoming more and more serious, the elderly and disabled travel, there is a problem in any country. How to solve this problem, which reflectsthe developed degree of a society from the level of science and technology to the humanistic care and other aspects of the. Our attention to this situation or not, that is no easy installation in vehicles off disabilities on facilities, this concern degree. The arrangement oflifting system for disabled people in the car, can improve the above situation.The disabled to pedal accessibility, and realize the company by personnel, andtrained personnel to operate this set of machinery, control to complete the disabledspecial automobile seat lifting system, to enable the disabled smoothly on the trainobjective. Should first in-depth discussion from the feasibility scheme of the mechanism, through the hands of the power unit, and then after repeated and carefulfeasibility, safety analysis and correction of motion,.
