Technical solution：The present invention is to reach goal of the invention by following measure, using completely different with the prior art Separated movable axis is flexibly connected framework, and the six sufficient Round-backed armchair of steel tube for carrying movable castor are pulled with intelligent transmission base, realize nothing The all-around mobile pattern or 360 degree of zero turn radius patterns in situ that need to be turned to.Managed with four identical H hinged in chair framework part Three groups of chair frame components with movable castor, then surround hexagon seat surface with a grafting H pipe and form positive six squares base；With flexibility Take brain, fupport arm, handrail, controller and the saucer part of joint connection form hexagon chair circle；With more on three groups of chair frame components The night bolt installed on layer partition plate or seat board hexagonal is inserted into height adjusting holes to adjust the height of seat；Foreleg is rotated to both sides (lower section) can widen the big side of seat surface and change chair circle angle, with the height of height adjusting holes adjustable handrail；Below seat Latch fixes backboard lower end；Six chairs select universal caster wheel enough.Coupling arrangement is by Revolving chair chassis, gas bar lifting shaft, adjustment gas Bar height pulls handle, and chair body rotates latch, collector ring (power supply and signal between connection controller and motor) group with axis Into driving device is the two hub-type motors (Electric Motor Wheel) and battery pack that rocker-type intelligence Universal direction controller manipulates.

Different from the axle steer structure of rigidly connected Integral electric wheelchair, separate type omnidirectional electric wheelchair is by carrying Formula seat and the whole load of movable castor carrying, the horizontally tracting of two Electric Motor Wheels offers is obtained by hinged swivel chair lifting shaft Power.The mutually reverse vertical rotaries of two motors can make horizontal any degree zero turn radius of 360 degree of stationary spindle, and chair body can be with Need not be with CircOlectric to the direction of seat also need not be consistent with the trend of Electric Motor Wheel when mobile, similar to the rotation of tank Holder on formula gun turret or movies-making railcar, without turning to for moved seat or being moved for seat stearing It is dynamic, so as to greatly improve the mobility of wheelchair, it can promptly pass in and out narrow and small indoor place.Pulling lifting shaft handle can To adjust the state that lands of movable castor and Electric Motor Wheel.Gradient that fupport arm handrail and back pad are formed with seat surface, backboard institute are S-shaped Curvature is all identical with round-backed armchair, and six fold-type chair circle moulding and the bending shape of human body arm coincide substantially, fully meet Comfort, stability and passability requirement, upper lower part of the body appropriateness ratio is adjustable, is more in line with base of principle of human engineering.Appearance forrns On remain the style moulding of traditional classical circle chair with back substantially, the lines brevity and lucidity of six square frameworks, harmonious line style is sane Steady and sure rule, three dimensions perfect adaptation, straight line (vertical line, horizontal line, broken line, oblique line) aesthetic feeling of collection saliency building geometry, The humanism connotation said of square-outside and round-inside is contained in rotating circular wheel built in collocation, the moulding that Fang Yuyuan is combined.Can be with minimum Floor space obtain the convolution space of maximum driving wheel and universal wheel, it is steady that the pitch difference of diagonal sum opposite side can take into account statement The requirement of qualitative and arrow path passability, minimum radius of gyration and minimum commutation width are significantly better than professional standard.It is outgoing carry or Folding can be easily and quickly dismantled during accumulating.It can also be used when driving device is not required as common round-backed armchair.

Omnidirectional's electric wheelchair has pushed the mobility of indoor type electric wheelchair, agility and vision ornamental value to ultimate attainment, is Multifunctional seat in smart home, is not only suitable for handicapped and elderly's residential use, is more suitable for Healthy People in multiple indoor Public place uses.
