A trolley for assisting the elderly to walk

Abstract

The invention discloses a trolley assisting the elderly in walking. The trolley comprises a bottom frame and driven rollers, walking mechanisms are arranged on two sides of the bottom frame, each walking mechanism comprises a rear shaft, a front shaft, a transmission shaft, a first supporting plate, a second supporting plate, a third supporting plate and a motor. Shaft arms of the rear shaft, thefront shaft and the transmission shaft are all connected to a side face of the bottom frame in a limiting and rotating mode. The first supporting plate, the second supporting plate, the third supporting plate and the motor are all fixedly connected to the side face of the bottom frame. A rear driving wheel is fixedly connected to a shaft arm of the rear shaft, a front driving wheel is fixedly connected to a shaft arm of the front shaft, a rotating plate is hinged to one end, away from the bottom frame, of the first supporting plate, a rotating shaft is rotatably connected to one end, away fromthe bottom frame, of the rotating plate in a limited mode, and a pressure roller is fixedly connected to one end, away from the rotating plate, of the rotating shaft. Through cooperation of the structures, the technical problems proposed in the background technology are effectively solved.

Description

technical field [0001] The invention relates to the technical field of auxiliary trolleys, in particular to a trolley for assisting the elderly in walking. Background technique [0002] Due to the inconvenient legs and feet of the elderly, they often need to rely on wheelchairs when they go out for a walk. Traditional wheelchairs are mostly two-wheeled, so when encountering potholes, the wheels are easy to fall into the potholes and are inconvenient to move. Thus, as shown in Chinese patent CN201811448971.7 Disclosed is a walking trolley. The invention includes a storage frame. The storage frame includes a bottom plate and four side plates. The outer sides of the side plates on both sides of the storage frame are respectively connected with a walking track, and the two ends of the walking track are respectively sleeved on a front drive wheel and a On the rear driving wheel, the front driving wheel and the rear driving wheel are driven by the driving device arranged on the st...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a trolley for assisting the walking of the elderly, which can be driven by a mechanical structure at the initial stage when the pressure roller encounters a pothole and sinks, so that there is a speed difference between the front drive wheel and the rear drive wheel. In order to make the pressure roller press down on the track more smoothly, it solves the problem of using multiple motors to drive four wheels respectively, multiple pressure sensors to detect the surface pressure of the pressure roller and multiple speed regulators to adjust the speed in the prior art. Increased manufacturing cost and relatively high demand for control accuracy, and when multiple electrical components are damaged, the maintenance cost is also relatively high
