Abstract
The utility model discloses an electric-control motor-drive chair used for handicapped people. The electric-control motor-drive chair used for handicapped people is composed of an operating handle and a control circuit plate which are arranged on the rack of an ordinary wheelchair and an electric control drive system composed of a double-sleeve battery, a motor, a speed reducer and a friction wheel. The utility model which can travel in wards, study rooms, living rooms, corridors, and stages has the advantages of small volume, flexible operation, one-hand control, and convenient maintenance.
Description
A kind of electricity powered chair coach is suitable for the vehicles that the people with disability uses.
Sell on the market now, can electro-tricycle, motor motor tricycle, hand-propelled tricycle and manual pulley Wheel-chair etc. be arranged for the vehicle that the people with disability uses.Above-mentioned four kinds of vehicles all need bimanualness.Operating physical force and operation amplitude are all bigger.Bring certain difficulty can for like this single armed disabled person's use.Electro-tricycle and motor motor tricycle travel speed are very fast, and general user of service's reaction is not come, and occurs accident easily.Hand-propelled tricycle and manual pulley Wheel-chair also need manpower to drive, and it is bigger to consume one's strength, and stroke is restricted, and in addition, four kinds of above-mentioned general volumes of vehicle are bigger, and inconvenience is used in indoor, stage or corridor.
The purpose of this utility model provides a kind of manipulated with one hand, realizes the electronic chair coach of miniaturization of automatically controlled turning.
The purpose of this utility model is achieved in that it is on the common basis of being made up of vehicle frame, seat, backrest, driving wheel and universal wheel of taking turns Wheel-chair commonly used, installs control crank, control circuit board again additional and the electric control driving system of the adjustable direction be made up of two cover storage batterys, motor, decelerator, friction pulley; The potentiometer of control crank and control circuit board links, after linking, storage battery and potentiometer link with the input of control circuit board again, the outfan and the motor of control circuit board link, the output shaft and the decelerator of motor link, on the output shaft of decelerator friction pulley is installed, friction pulley is pressed against on the excircle of driving wheel cover tire of chair coach; Entire circuit on the control circuit is made up of the identical pulse wide modulation circuit of two-way electric elements.The energized switch, chair coach can advance; Change the resistance value at potentiometer two ends by control crank, just can realize chair coach about turning.
Be described in detail structure of the present utility model as follows more in conjunction with the accompanying drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cutaway view at this utility model A-A place in Fig. 1.
Fig. 3 is that the electric elements of the control circuit board in this utility model connect sketch map.
From Fig. 1 and Fig. 2 as can be seen, on the common basis of taking turns Wheel-chair that the electricity powered chair coach that this utility model is recommended is made up of vehicle frame 1, seat 2, driving wheel 3 and universal wheel 4, on vehicle frame 1, install control crank 5, storage battery 6(6 ' again), control circuit board 7, motor 9(9 '), decelerator 10(10 ') and friction pulley 11(11 ') and constitute; Friction pulley 11(11 ') be installed in decelerator 10(10 ') output shaft on, and be pressed against driving wheel 3(3 ') the excircle of cover tire on, form frictional drive; The potentiometer W of control crank 5 and control circuit board 7 links, storage battery 6(6 ') and potentiometer W link with the input of control circuit board 7 again after linking, the outfan of control circuit board 7 and motor 9(9 ') input link motor 9(9 ') take-off (propeller) shaft and decelerator 10(10 ') link; Because decelerator 10(10 ') on the output shaft friction pulley 11(11 ' is installed), and friction pulley 11(11 ') be pressed against driving wheel 3(3 ') the cover tire circumference on, so high speed rotating motor 9(9 ') is through decelerator 10(10 ') deceleration after, by friction pulley 11(11 ') drag driving wheel 3(3 ') rotate, advance thereby drive the chair coach of recommending in this utility model.
It is pointed out that the control circuit board 7 that adopts in this utility model, as can be seen from Figure 3 it is by the identical alignment circuit of two-way electric elements, and its outfan and electric drive system separately link.In detail, be exactly to form a cover electric control driving system by the last lateral circuit in the control circuit board 7 and motor 9, decelerator 10, friction pulley 11, driving wheel 3; By the underside circuits in the control circuit board 7 and motor 9 ', decelerator 10 ', friction pulley 11 ', the another set of electric control driving system of driving wheel 3 ' form.Two cover electric control driving systems are by the potentiometer W control that links.
Electricity powered chair coach in this utility model is to handle like this and work: the potentiometer W swing arm in control crank 5 and the control circuit board 7 links, when control crank 5 during in the centre position, OA=OB, side a and b resistance equates, energized K switch 1(Fig. 3), the alignment circuit output voltage that two-way is identical equates, drive motor 9 and 9 ' rotation respectively, through decelerator 10 and 10 ' driving friction pulley 11 and 11 ', friction pulley 11 and 11 ' drive driving wheel 3 and 3 ' and the seat cathetus is advanced.
When needing to turn, pull control crank 5 towards respective direction and get final product.For example, control crank 5 is pulled left, the swing arm of the potentiometer W that links with it is shifted to A end (Fig. 3), and OA arm resistance reduces, and OB end resistance value increases.Two different signals input to the upper and lower both sides alignment circuit in the control circuit board respectively, the upside alignment circuit is received less voltage signal, through obtaining less voltage output after the processing of circuit, drive motor 9, decelerator 10, friction pulley 11, driving wheel 3 are to advance at a slow speed.The downside alignment circuit is received bigger voltage signal, through obtaining big voltage output after the processing of circuit, thereby drive motor 9 ', decelerator 10 ', friction pulley 11 ', driving wheel 3 ' advance fast.Two driving wheel 3,3 ' generation rotary speeds are turned car body.
The position of control crank 5, according to the user needs, can left-right reversed.
Little, the flexible operation of electricity powered chair coach volume in this utility model can start flexibly in indoor, corridor; Easy to maintenance, only needing regularly to charge in storage battery gets final product; Discharging waste gas not, no air pollution, what also should particularly point out is, and this utility model can one-hand control, and operating physical force is little; The speed of a motor vehicle can be regulated and control to walking speed, is suitable in the ward, study, room or stage etc. locate invalid personnel and use.For example hemiplegia personnel oneself can not use the common Wheel-chair of taking turns, and as using the electricity powered chair coach in this utility model, do not need other people just to help and can oneself solve the walking problem.
