Based on the shortcomings of the present wheelchairs, this paper proposes a kind of portable and labour-saving wheelchairs. This wheelchair uses a new drive mechanism constructed by rocker, friction ratchet mechanism and four bar mechanism, through rocker driving the floor wheel turning to change the force form to achieve labour-saving. In addition, the fork lever mechanism, slide block mechanism and screw nut consisting the lift mechanism makes the wheelchair seat can be lifting, which improve the self-care ability of the disabled. In conclusion, the portable and labour-saving lift wheelchair in the traditional wheelchair basis further expands its use function and has high practical value.
