Abstract
The present invention relates to a folded electric wheel-chair which is simple in structure and is convenient for handicapped. It comprises seat frame, double cross piece, electric wheel and hand-pushing wheel. A steel pipe is fixed on the middle portion of every pendulum arm formed into said double cross piece and is matched with outer diameter of the middle axle so as to make the pendulum arm be rotated by using the middle axle as shaft, the fornt portion of rear portion of the middle axle is connected with wheel frame, the electric wheel is mounted on said wheel frame, and on the middle axle a fastener is fixed, on the steel pipe of pendulum arm near by said fastener a fixture is fixed, between the fastener and fixture they are fixed by using bolt.
Description
Technical field
The present invention 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 objective of the invention 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 object of the present invention is achieved like this: 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 solutions according to the invention, 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.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the stereo appearance figure of existing foldable wheelchair.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the right view of Fig. 2.
Fig. 4 is the schematic perspective view of diesis frame of an embodiment of folding electric wheelchair of the present invention.
