Universal motion switching mechanism for electric wheelchairs

Abstract

The invention relates to a universal motion switching mechanism for electric wheelchairs. The universal motion switching mechanism for electric wheelchairs comprises two rotating shaft fixing plates, universal bearing castor mounting members, universal bearing castors, two mounting tubes, support rods, foot plates, ejector blocks, and a rotating shaft. The universal motion switching mechanism for electric wheelchairs is characterized in that the rotating shaft fixing plates and the mounting tubes are respectively fixedly connected to a base of an electric wheelchair, the rotating shaft penetrates the rotating shaft fixing plates, two ends of the rotating shaft are fixedly connected with the foot plates respectively, one ejector block is disposed at the upper end of each mounting tube and fixedly connected to the rotating shaft, one support rod is connected to the inside of each mounting tube through a spring, the lower end of each support rod penetrates the corresponding mounting tube and is fixedly connected with the corresponding universal bearing castor mounting member, the upper end of each support rod is in contact connection with the corresponding ejector block, and one universal bearing castor is mounted below each universal bearing castor mounting member. The universal motion switching mechanism for electric wheelchairs allows the electric wheelchair to be conveniently switched from electric motion to universal motion.

Description

technical field [0001] The invention relates to a universal movement conversion mechanism for an electric wheelchair, and is particularly suitable for an electric wheelchair driven by a rear wheel. Background technique [0002] With the aging of my country's population and other accidents, more and more people have limb dysfunction and need to use wheelchairs as a means of transportation. In wheelchairs, more and more users tend to use electric wheelchairs. Electric wheelchairs have the characteristics of labor-saving and comfortable, but to a certain extent, there are problems such as inconvenient steering, difficulty in translation and lateral movement. It is very difficult to transfer the wheelchair and the wheelchair to a safe and suitable position, and it is difficult for one person to achieve it. And so far there is no electric wheelchair at home and abroad that can reasonably solve the above problems. Contents of the invention [0003] In order to solve the probl...
