Rear power-assisting intelligent driver

Abstract

The invention discloses a rear power-assisting intelligent driver. A universal wheel comprises a wheel hub, end covers are fixed to openings in the two ends of the wheel hub respectively, the two endsof an electric driving mechanism penetrate through the end covers respectively and are supported on the end covers, and at least two rows of running pulleys which are arranged in the circumferentialdirection of the wheel hub are movably assembled on the circumference of the wheel hub. The rear power-assisting intelligent driver further comprises a shell, supporting arms which extend in the axialdirection of the shell are symmetrically arranged at one end of the shell, an assembly space is formed between the two supporting arms, after the universal wheel enters the assembly space between thetwo supporting arms, the two ends of the electric driving mechanism are connected with the supporting arms respectively, the other end of the shell is used for being hinged to the rear portion of a wheelchair, and the universal wheel is in contact with the ground under the effect of gravity; a storage battery is arranged in the shell; a controller is located in the shell and is electrically connected with the storage battery, and the output end of the controller is electrically connected with the electric driving mechanism. The rear power-assisting intelligent driver is assembled at the rearportion of the wheelchair to assist the wheelchair in running, and does not influence the comfort of the wheelchair.

Description

technical field [0001] The invention relates to a rear power-assisted intelligent driver suitable for transportation tools such as wheelchairs or carts. Background technique [0002] The wheelchair is an important tool for rehabilitation. It is not only a means of transportation for the physically disabled, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of wheelchairs. Therefore, people have higher and higher requirements for the flexibility of wheelchairs. [0003] The traditional universal wheel is driven by external force, and the direction of the wheel needs to be changed to move, and when the external force changes the direction of movement, the wheel needs a process of adjusting the direction of the wheel, which is not flexible to use. Moreover, the direction in which the wheel is subjected to load deviates from the center of the wheel, causing the wheel frame to generate an eccentric moment, makin...

Problems solved by technology

[0005] For the above-mentioned universal wheel is used for the front wheel or the rear wheel of the wheelchair, although the two rows of rollers arranged in the circumferential direction of the hub are staggered, but because the Y-shaped projections of the supporting rollers are interrupted, there are wheelchairs on the wheel. There are undulations during driving, that is, bumps, which reduce the comfort of the wheelchair
