Abstract

The utility model provides a power-driven wheel chair, which comprises a wheel chair chassis, an engine assembly, a wheel chair frame, a pedal, a shock absorber and a control device. Wherein, the engine assembly is embedded in the middle of the wheel chair chassis. An upper part of the engine assembly is connected with a bottom of the wheel chair frame. The control device is arranged on both sides of the wheel chair frame. In addition, the pedal is positioned at a front end of the wheel chair chassis. An upper part of the shock absorber is connected with the wheel chair frame and a lower part is respectively connected with the engine assembly and a front end of the wheel chair chassis. Compared with prior arts, the power-driven wheel chair of the utility model is characterized by rational design, simple structure, easy processing, small size, high safety, labor saving, flexible steering, novel shape, great stability, strong performance and adequate power, thus showing favorable promotion and utilization.

Description

Motorized wheel chair

1, technical field

This utility model relates to a kind of wheelchair, specifically a kind of motorized wheel chair that power is provided with electromotor.

2, technical background

At present, existing wheelchair has two kinds of hand propelled and electrodynamic types on the market.Hand propelled wheelchair style is old, poor stability, and effort is that patient or family members are not the part easy things if think to go for a trot easily again; Though electric wheelchair has solved above drawback, all be to do the influence that power is subjected to battery life with storage battery, ruggedness neither be very strong, and the charging interval is generally all very long, must have second people's help just passable if charge, and uses extremely inconvenient.

3, summary of the invention

The purpose of this utility model provide a kind of simple in structure, production cost is low, safety labor-saving, turn to flexibly, modern design, motorized wheel chair that stability is good.

The purpose of this utility model realizes in the following manner, the engine assembly inlay card is constituted the wheelchair chassis between both arms propons and back axle, to take turns seat support is arranged on the wheelchair seat supports frame, and on wheelchair seat supports frame mounting shock absorber, on special both arms propons, install the pedal that upwards to do 90 ° of rotations along turning cylinder additional, when patient need be with wheelchair, upwards rotate pedal, make pedal be in the engine assembly right-hand member of wheel below the seat support, patient puts down pedal after taking wheelchair again, just can carry out operation control of the present utility model.

Accompanying drawing 1 is the main TV structure sketch map of motorized wheel chair;

Accompanying drawing 2 is the structural representation of looking up of motorized wheel chair;

4, description of drawings

Explain below with reference to Figure of description motorized wheel chair of the present utility model being done.

Motorized wheel chair of the present utility model, its structure are by front-wheel 1, both arms propons 2, trailing wheel 3, back axle 4, engine Assembly 5, wheel seat support 6, wheelchair seat supports frame 7, back bar 8, pedal 9, damper 10, left joystick 11, Right joystick 12, handle coupling spindle 13, flame-out button 14, start button 15, control handwheel 16, controller 17 structures Become, front-wheel 1 is arranged on the both arms propons 2, and trailing wheel 3 is arranged on the back axle 4, and engine assembly 5 inlay cards are at both arms propons 2 And between the back axle 4, its upper end joins with wheelchair seat supports frame 7, and pedal 9 is arranged on the top of both arms propons 2, damping Device 10 1 ends and wheelchair seat supports frame 7 join, and the other end joins with both arms propons 2 and engine assembly 5 respectively, wheelchair Seat 6 is arranged on the top of wheelchair seat supports frame 7, and its both sides are provided with left joystick 11 and right joystick 12, steering gear 17 are arranged on wheel seat support 6 forequarters, and the top of steering gear 17 is provided with and turns to handwheel 16, and the lower end of steering gear 17 is passed through Connecting rod and both arms propons 2 join. The upper rear end of wheel seat support 6 is provided with back bar 8.

5, embodiment

Its processing and fabricating of motorized wheel chair of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.The both arms propons is welded into similar U type structure with steel processing, and back axle is processed into O type structure, and engine assembly is made with the motorcycle engine repacking.

Its concrete operations of motorized wheel chair of the present utility model are as follows:

Patient, particularly single leg disease people is before last wheelchair, earlier pedal is upwards gone under the wheel seat support, again pedal is put down and steps on thereon after patient gets on the bus, press the start button ato unit, promote left and right joystick oiling starting forward, in advancing, regulate the throttle size and turn to handwheel adjusting direct of travel according to road conditions, promote left and right joystick backward in order to brake, switch-off only need be pressed flame-out button and get final product.

Motorized wheel chair of the present utility model is compared with existing technology, have reasonable in design, simple in structure, be easy to processing, Volume is little, safety labor-saving, turn to flexibly, modern design, the characteristics such as stability is good, power is sufficient, thereby, have Good popularizing value.

Except the described technical characterictic of specification, be the known technology of those skilled in the art.
