| Abstract: | A center of gravity self-regulation style multifunctional medicinal vehicle was developed, using pinion and rack, make this product easily to switch among medicinal vehicle, sickbed and wheelchair, the chiefly characteristic is center of gravity self-regulation, the motion of the parallel link mechanism was drive by screw mechanism, and the parallel link mechanism coupling with pinion and rack through connecting rod, driving the trailing wheel moving back and forth to adjust the outreach of the universal wheel and the trailing wheel, for the purpose to keep security. By testing it, the bicycle performans nice, suitable for many occasions. |
