Abstract
An electric wheelchair vehicle is composed of a wheelchair vehicle, a motor, a battery, a speed controlling regulator, and a charger. The invention relates to a portable vehicle which is designed on the basis of bicycles according to the special needs of disabled people with bad lower extremity and is especially used by disabled people, and some technical requirements of the invention are more difficult than those of electric bicycles, and the achievement of economical and practical objectives is more difficult than that of electric bicycles. The invention can be realized on present engineering level and the sample vehicle is being developed.
Description
Technical field
The present invention is by the hand Wheel-chair of taking turns.The electric wheel-chair vehicle of formations such as motor, accumulator, control speed regulator, charger is for special-purpose light the riding instead of walk with the vehicles (seeing accompanying drawing) of lower limb disability people individual.
Background technology
At present the lower limb disability people goes on a journey usually with crutch, handly takes turns special-purpose motor tricycle (its energy major part gasoline of people with disability that Wheel-chair (hand-propelled tricycle) is used for manned loading, some is that gasoline, accumulator are share, and seldom is to use accumulator) trip of riding instead of walk.
Summary of the invention
The lower limb disability people uses the crutch trip.It is ineffective to be slow in action: just.Can do riding instead of walk of longer distance though use the hand Wheel-chair of taking turns.But speed is slow and the people is under a strain.The people with disability's special use motor tricycle that uses in the urban district now: major part is the transport vehicle in manned loading for disabled persons.The utmost point: be used to the trip of riding instead of walk less.Promptly being used in the individual rides instead of walk.Also exist inconvenience and shortcoming: 1, volume is big, and it is big to take the road surface, parks inconvenience.The heavy manpower of car load is difficult to drive, and 2, to air pollution serious (most two-stroke or low-grade four-stroke gasoline engine of using); 3, noise is big; 4, individual cost of use is big, and 5, that gasoline leaves family in is dangerous with own interpolation gasoline.Dangerous big, 6, the car load maintenance of being out of order easily is inconvenient, 7, the car load price is expensive concerning the people of general income; 8, driving needs training, examination, just can obtain driver's license.More than all inconvenience that present lower limb disability people trip is described invariably and helpless.
The inventor is accommodating in order to help the lower limb disability people to go out.Collect a large amount of technical data through conscientiously studying, done a large amount of experiments.Finally finished the present invention.And basic verification its feasibility.
The objective of the invention is in order to provide a kind of light, quick to the lower limb people with disability, no atmospheric pollution, noiseless, convenient driving.Safety in utilization is big, and cost of use is little, and fault rate is low, and is easy to maintenance, the trip running vehicle of car load moderate cost.Another object of the present invention provides the basic skills of making above-mentioned electric wheel-chair vehicle.
The critical piece that the present invention uses has following several:
1, through not counting improved three-wheel wheel Wheel-chair again.The wheel Wheel-chair is formed (seeing accompanying drawing) by bicycle handle bar, front and back wheel brake handle, stepless speed regulation handle, front fork, single front-wheel, wheelchair frame (the vehicle frame requirement is made into can lay motor, accumulator, control wither fast device, charger etc. under the medicated cushion), medicated cushion, back pad, handrail, wind and actuating device (not essential), two trailing wheels, trailing wheel brake component etc.
2, dc motor is one: 24 volts of motor rated voltages, rated power about 200 watts (determining according to practical situation), rotors output rated speed are to sit fixed pattern at the bottom of the common cylinder formula less than 1500 rev/mins of (concrete rotating speed is determined as required), motors again.
3, lead-acid accumulator is two: single accumulator capacity be 12 volt of 17 ampere-hour (can look for as requested once distance that electricity need travel determine capacity greatly/little), general two 12 volts; The accumulator of 7 ampere-hours once charges and discharge about 40 kilometers of electric energy drivings.
4, battery charger: charge power supply is 220 volts 50 hertz a alternating current power supply.The output voltage electric current mates according to the accumulator practical situation.Charger need have safety precautions (promptly will protect personal safety, it is bad to protect accumulator not filled again).
5, control speed regulator: can capture to the stepless accent of direct current generator.Protection motor and accumulator are normally used, and under-voltage advance notice of accumulator and under-voltage outage (protection accumulator) are arranged.
More than five big parts be to constitute fundamental of the present invention and basic manufacture method.
The specific embodiment
The important technological parameters that the present invention's requirement reaches is as follows:
1, two 12 volts, the accumulator of 17 ampere-hours fill once electric continual mileage greater than more than 30 kilometers.Generally about 40 kilometers.、
2, max. speed is not more than 20 kilometers/hour.Or determine according to the regulation of public security traffic portion.It is more suitable that the inventor appraises and decides about 15 kilometers/hour of the normal speed of a motor vehicle.
3, maximum running noise is not more than 60 decibels.
4, can static starting under the situation of power-assisted not and do not damage motor and accumulator.
5, climbing capacity generally wishes the situation of power-assisted not be issued to 4 spend more than.
6, the life of storage battery is generally more than 1 year.
7, when electric wheel-chair vehicle travels with 18 kilometers/hour speed.Its dry state braking distance should be not more than 4 meters.
Owing to also do not have a this electric wheel-chair vehicle now, more than listed important technological parameters be that the inventor draws up.Technical situation and experimental result according to my grasp.If can reach above important technological parameters, electric wheel-chair vehicle then of the present invention brings convenience with economical and practical for lower limb disability people's trip.
