Voice remote control intelligent wheelchair

Abstract

The embodiment of the invention discloses a voice remote control intelligent wheelchair. The wheelchair comprises a wheelchair base and a wheelchair backrest installed on the wheelchair base. The wheelchair base comprises a base frame plate used for bearing. The supporting leg rods on the same side are respectively arranged on two parallel side plates of the base frame plate in a crossed manner; arolling wheel is mounted at the lower end of each supporting leg rod on the same side; the base frame plate is provided with a servo motor used for adjusting and maintaining the cross angle of the supporting leg rods on the same side, a positioning anti-jolt mechanism is arranged between the supporting leg rods on the same side, the servo motor indirectly adjusts the height of the wheelchair baseby adjusting the included angle of the supporting leg rods on the same side which are arranged in a crossed mode, and the positioning anti-jolt mechanism indirectly ensures that the wheelchair stablywalks on the uneven ground by maintaining the four rolling wheels in the same plane. The gravity center of the wheelchair in the moving process is lowered according to the flat road surface, the overall stability of the wheelchair in the using process is improved, and rollover of the wheelchair in the using process is effectively avoided.
