Description
Technical field
The present invention relates to a kind of electric wheelchair.Belong to technical field of medical instruments.
Background technology
Electric wheelchair is people's medical auxiliary implement in order to ride instead of walk in daily life of the shortage independent rows kinetic forces such as old man, physical handicaps and chronic sufferer of neuromuscular pathological changes person, functional degeneration.At present, in hospital and daily life, patient or old handicapped person generally adopt the wheel Wheel-chair as walking-replacing tool.Wherein, in the driving wheel electric wheel-chair vehicle be exactly a kind of more common a kind of, this Wheel-chair of taking turns includes preceding universal wheel, driving wheel, three groups of wheels of back universal wheel, front-wheel mainly play the guiding role, the middle driving wheel that drives links to each other with dynamical system, back universal wheel is used to keep whole balance of taking turns Wheel-chair, when climbing or topping bar, play the effect of stable support, because three groups of wheels are set altogether, therefore the ground ability of grabbing of driving wheel just becomes the sport technique segment that must be paid attention in, especially on the road surface comparatively smooth or the wheel Wheel-chair when climbing step, it is particularly outstanding that this problem just seems, skidding will appear in ability inadequately if middle driving wheel is grabbed ground, the phenomenon that can't pass through smoothly, until causing operational hazards, and the force-bearing situation of middle driving wheel and to grab the ground ability closely related with the high and low position of preceding universal wheel moves after the center of gravity of the higher then car load in preceding universal wheel position, before universal wheel is stressed reduces, middle driving wheel then is subjected to bigger pressure, climbs and grab the ground ability to be enhanced.In order to increase climbing and to grab the ground ability, existing person in the industry realizes by dual mode, and a kind of is that preceding universal wheel is liftoff and make micromatic setting, adjusts according to the requirement of road conditions; Another kind is between preceding universal wheel liftoff and pro-universal wheel and the vehicle frame shock absorption buffering mechanism to be set, and this structure only just can play effect on specific road conditions, and it grabs the ground ability in the time of on the road surface of level and smoother just significant limitation.
Electric wheelchair all is to be controlled by microcomputer controller, and dynamical system is driven by two AC permanent magnet motors, and two AC permanent magnet motors are realized the straight line moving and the turning action of wheelchair by the electronic differential principle.Because the variation of turning acceleration and turning deceleration during the electric wheelchair operation, the deviation of gravity center driving wheel axis center of electric wheelchair far can produce dizzy impression to the occupant, even cause occupant's the secondary injury old man of diseases such as hypertension (especially for), so the sport technique segment that must be paid attention to of the center of gravity of electric wheelchair.Especially take turns electric wheelchair for six, wherein back universal wheel, middle driving wheel land, the preceding liftoff electric wheelchair of universal wheel, it is particularly important that this problem seems, the position relation of adjusting center of gravity and middle driving wheel guarantees occupant's comfortableness, this problem very contradiction that just seems simultaneously with assurance electric wheelchair stability.
Travel when taking the electric wheelchair leaping over obstacles or on rugged road surface, the stability and the comfortableness of wheelchair operation are most important, and to taking the personage who uses electric wheelchair, its health can't be born the vibrations that cause owing to jolting mostly; Electric wheelchair requires to have the automatically load compensating function so that electric wheelchair stable travelling on rugged road surface.Therefore the damping design and the automatically load compensating of electric wheelchair are the another sport technique segments that must be paid attention to of electric wheelchair.Wherein the damping design can realize in the chassis structure of electric wheelchair, and the automatically load compensating functional requirement is dynamo-electric in conjunction with just making the occupant reach best ride effects.
Because all having height, general road rises and falls, the indefinite situation of jolting, ladder for example, or the road surface of projection etc., therefore electric wheelchair need have the ability of leaping over obstacles, simultaneously necessary shock-absorbing function to be arranged, for improving above-mentioned defective, a kind of electric wheelchair is disclosed in Chinese patent CN 201042485Y, it distinguishes pivot in the same position of vehicle frame with preceding universal wheel and driving wheel, replaced preceding universal wheel and be connected rigid structure with driving wheelchair one, and an elastic component is set between preceding universal wheel and driving wheel, replace complicated linked component, so that the buffering of relative this vehicle frame pivot pendulum with this driving wheel of this preceding universal wheel to be provided.Above-mentioned technology provides a kind of electric wheelchair, so that preceding universal wheel and middle driving wheel are distinguished pivot in the vehicle frame same position, to replace the one rigid structure of known preceding universal wheel and driving wheel, and between preceding universal wheel and middle driving wheel, an elastic component is set, to replace the linked component of known complexity, so that the preceding universal wheel buffering of this vehicle frame pivot pendulum relatively to be provided, to have the member exquisiteness, design and produce advantages such as easy, that cost of manufacture is low, the assembling maintenance is easy and durable.But pass through the stage clip damping before this wheelchair between universal wheel and the middle driving wheel, under the effect of wheelchair at gravity, the angle of front driving wheel and middle driving wheel can reduce, when center of gravity is amesiality, lateral tilt can take place in wheelchair, can not guarantee that the occupant is in a kind of comfortable state all the time.Simultaneously this electric wheelchair is connected making elastic component between preceding universal wheel and the middle driving wheel, then middle driving wheel grab ability will be weakened corresponding climbing capacity and climb up and over the ability that hinders and decrease.
A kind of wheelchair Herba Plantaginis castor micro-adjusting mechanism is disclosed among the Chinese patent CN 2839006Y, comprise forward foot in a step wheels, middle wheels, rear foot wheels and drive system assembly, middle wheels link to each other with the clutch end of drive system assembly, rear foot wheels are fixed on the top of drive system assembly, forward foot in a step wheels are provided with the support arm towards rear truckle, the top of drive system assembly is provided with mount pad, offer chute hole on the mount pad, the support arm end of forward foot in a step wheels offers installing hole, this installing hole is passed in one rotating shaft and chute hole is hinged with front truckle and mount pad, also is provided with on the mount pad to be used for adjusting the clamp device of rotating shaft at the chute hole sliding position.Adjust the universal wheel terrain clearance by this device.When this mechanism was applied on the electric wheelchair, front-wheel was liftoff in the process of normally travelling, and only front-wheel just can land when climbing, the ground ability of grabbing of driving wheel in the increase, the climbing capacity of lifting electric wheelchair.When on slick road surface, travelling, adjust the terrain clearance of front-wheel again, can not reach the function of self adaptation road conditions, user has been brought very big inconvenience.
Summary of the invention
