Multifunctional automatic wheelchair

Abstract

The invention relates to a multifunctional full-automatic wheelchair, which comprises four parts: an adjusting device, a lifting device, a moving device and a folding structure. The adjusting device realizes the angle adjustment of the wheelchair by controlling a steering gear to drive relevant gears, worm gears, racks and connecting rod parts, and has strong functionality. The lifting device controls the height of the wheelchair through the expansion and contraction of three push rod motors, and has strong adaptability. The moving device uses a single chip microcomputer to drive the motor andthe steering gear to realize forward moving, backward moving and steering of the wheelchair. The folding structure is connected with the push rod motors through a steel wire rope, and the push rod motors drive the steel wire rope and a spring to cooperate to drive the lifting and lowering of supporting wheels, so as to realize the function of the wheelchair from the contracted state under the bedto the state to be used at the bed side. In addition, the structure is novel.

Description

technical field [0001] The invention relates to the fields of machinery and electricity, in particular to a multifunctional full-automatic wheelchair device. Background technique [0002] According to relevant data, it is estimated that in 2030, the number of people over 65 years old in China will surpass that of Japan, becoming the country with the highest aging population in the world. The rapid development of aging has aroused the attention and concern of the United Nations and governments all over the world.
