Abstract

The utility model relates to a folding electric wheelchair which is simple in structure and is easy to be used by the people with disabilities, comprising a base frame, a double-cross frame, an electric wheel and a hand-push wheel, the utility model is characterized in that: the middle part of each swing rod which constitutes the double-cross frame is fixedly provided with a steel pipe which is matched with the outer diameter of a middle shaft, thereby enabling the swing rods to rotate by taking the middle shaft as the shaft, the front part or the back part of the middle shaft is connected with a wheel frame, the electric wheel is arranged on the wheel frame; a fastener is fixedly arranged on the middle shaft, a fixed part is fixedly arranged on the steel pipe of the swing rod which is near to the fastener, and the fastener is fixed with the fixed part through a bolt.

Description

A kind of folding electric wheelchair

Technical field

This utility model relates to a kind of wheelchair, particularly a kind of folding electric wheelchair.

Background technology

Existing folding wheel chair is as Fig. 1, Fig. 2, shown in Figure 3; Wherein Fig. 1 is the axonometric chart of existing folding wheel chair, and Fig. 2 is the side view of Fig. 1, and Fig. 3 is the right view of Fig. 2; Two the less support wheels 17 of hand-pushing wheel 16 and mounting the place ahead that comprise mounting 13, diesis frame 12, mounting both sides, two crosses 12 are made of the fork that two middle parts are articulated on the pivot pin 14 respectively, when two forks can be folded into wheelchair portable structure when bearing pin 14 rotates.This wheelchair must respectively be provided with support 18 in order to support wheel 17 to be installed along two hand-pushing wheel sides, and its shortcoming is a complex structure, and does not have motor drive mechanism, is not easy to the individuals with disabilities and uses.

Summary of the invention

The purpose of this utility model is in order to solve the complex structure that exists in the existing foldable wheelchair, do not have motor drive mechanism, to be not easy to the problem that the individuals with disabilities uses, and provide a kind of simple in structure, be convenient to the folding electric wheelchair that the individuals with disabilities uses.

Technical scheme:

The purpose of this utility model is achieved in that a kind of folding electric wheelchair, comprise mounting, diesis frame, Electric Motor Wheel and hand-pushing wheel, the middle part that it is characterized in that constituting every fork of diesis frame is fixed with the steel pipe that matches with the axis external diameter, making fork can be that axle rotates with the axis, the front portion of axis or rear portion are connected with wheel carrier, and Electric Motor Wheel is installed on this wheel carrier.Two hand-pushing wheels and an Electric Motor Wheel land and support whole chaptrel chair, and Electric Motor Wheel is by driven by power, and the user can drive wheelchair by electrification at ordinary times, when battery is not electricity, can use the hand propelled hand-pushing wheel.

Described folding electric wheelchair is characterized in that being fixed with securing member on the described axis, is fixed with fixture on the steel pipe near the fork of this securing member, uses bolting between securing member and the fixture.Its effect is to prevent steel pipe and middle between centers circular runout, and in the time of wheelchair being folded, only need unload bolt and get final product.

Beneficial effect:

Owing to adopted technical scheme described in the utility model, Electric Motor Wheel is set on axis, made things convenient for individuals with disabilities's use, securing member and fixture are set respectively on steel pipe and axis, safe, and also this is simple in structure.
