The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, electrical salf-walking stair climbing wheelchair car described in the utility model, comprise wheelchair frame 1, seat 2 and be arranged on the running gear of wheelchair frame 1 bottom, on described wheelchair frame 1, be provided with the horizontal automatic regulating apparatus of seat, the horizontal automatic regulating apparatus of described seat comprises two rear bearing blocks 3 that are symmetricly set on wheelchair frame 1 rear portion, on described rear bearing block 3, be connected with swing arm 5 by rear swinging axle 4, in described swing arm 5 upper ends, be connected with amortisseur 6, described amortisseur 6 upper ends are hinged by suspension ring 7 and seat 2 sidewalls, in described swing arm 5 lower ends, be provided with accumulator battery 10, at described accumulator battery 10 side of being provided with, bottom taper balancing weights 11, described running gear comprises the electronic climbing walking mechanism that is symmetricly set on wheelchair frame 1 rear end, the electronic level walking mechanism that is arranged on wheelchair frame 1 front end and ensures the climbing walking mechanism, and correspondence is provided with forward and backward control crank 8,9 respectively in the rear and front end of described seat 2, described electronic climbing walking mechanism comprises that being symmetricly set on wheelchair frame 1 rear end is driven two five combination wheels of cranking arm of its rotation through worm-gear speed reducer by motor by accumulator battery 10, described five crank arm, and combination wheel comprises rear-wheel hub 12 and along its peripheral radial uniform five jib 13 after arc-shaped bend in the same way, scroll wheel 14 after the end of jib 13 after described arc-shaped bend is provided with, scroll wheel 14 inboards are provided with special-shaped eccentric 15 after on jib 13 after described arc-shaped bend, being positioned at, described electronic level walking mechanism comprises with the motor wheel 16 of brake device and is arranged on the front-end bearing pedestal 17 of wheelchair frame 1 front portion, described motor wheel 16 is connected with wheel fork pipe spreader 19 by wheel fork 18, described wheel fork pipe spreader 19 is connected with front-end bearing pedestal 17 by front swinging axle 20, and the wheel fork shaft upper end in described wheel fork pipe spreader 19 is provided with the steering operation bar 21 be connected with front operating grip 8 elasticity, described guarantee climbing walking mechanism comprises two three curved boom combination wheels that are symmetricly set on wheelchair frame 1 front end, described three curved boom combination wheels comprise front hub 22 and along its peripheral radial uniform three jib 23 before bending shape in the same way, before described bending shape jib 23 middle parts be provided with before scroll wheel 24, the end of jib 23 is provided with auxiliary wheel 25 before described bending shape, and the diameter of described auxiliary wheel 25 is less than the diameter of front scroll wheel 24.Front scroll wheel 24 diameters are less than rear scroll wheel 14 diameters, and jib 23 length are less than jib 13 length after arc-shaped bend before bending shape.In use, it is separate at level walking and the electric walking controlling organization of walking on stair that this utility model possesses two covers simultaneously, when level walking, motor wheel 16 and five is cranked arm on combination wheel after two scroll wheel 14 on same level, the occupant is sitting on wheel-chair and just as driving electro-tricycle, freely travels, very convenient, during the stair climbing slope, the occupant drives electrical salf-walking stair climbing wheelchair car back and is falling back and going upstairs facing to the stair slope, five crank arm on combination wheel connects electric power switch after scroll wheel 14 after two that contact with ground is close to the risers of stairway step, five combination wheels of cranking arm rotate simultaneously, wherein after arc-shaped bend, the special-shaped eccentric 15 of two on jib 13 first contacts ledge surface simultaneously, because rocking before and after doing, 15 of special-shaped eccentrics do not do the circumference rolling, so at first it the five combination wheel smooth rotation of cranking arm as basic fulcrum support, secondly can also automatically adjust to the different stairway step of width size, make five scroll wheels 14 after each of cranking arm on combination wheel in the motion of climbing step, be close to the risers of step, being arranged on the three curved boom combination wheels that ensure the climbing walking mechanism cranks arm under the power traction of combination wheel five, auxiliary wheel 25 and front scroll wheel 24 on two three curved boom combination wheels carry out rotation and revolution on the surface of stairway step in succession, with the athletic posture that continues to climb, rotate, supporting the walking reposefully on the stair slope of whole wheel-chair.While going downstairs slope, taking the people drives downstairs facing to the stair slope, the walking states of wheel-chair is the same when going upstairs slope, it is only direction of motion difference, because motor power passes to five combination wheels of cranking arm through worm-gear speed reducer, so the auto-lock function of worm and gear can make the wheel-chair can be with walking with stopping in climbing and descending process, fool proof reliably, be arranged on the level walking mechanism of wheelchair frame 1 front portion, when wheel-chair stair activity slope, because the action of gravity of motor wheel 16 self makes its break away from the ledge surface on stair slope, it provides power only for wheel-chair when level walking, be arranged on the horizontal automatic regulating apparatus of seat on wheelchair frame 1, under the force action of occupant's self gravitation and accumulator battery 10 and square taper balancing weight 11 gravity, the rear swinging axle 4 that is arranged on two swing arm 5 upper positions of the left and right sides can be along with wheelchair frame 1 tilts forward and back the variation of angle and rotates in rear bearing block, thereby make swing arm 5 all keep all the time state straight down, and then the seat 2 that makes to be lifted on amortisseur 6 remains level, occupant's comfort and safety have greatly been increased, and before being arranged on two couple of seat 2 front and back ends, rear operating grip 8, the 9th, for different occupants respectively, the strong disabled people person of brain uses the operating grip 8 of front can oneself drive electrical salf-walking stair climbing wheelchair car and travels, without the personnel of driving ability, taking other adults in nurse Shi Keyou or family uses the operating grip 9 of back to help operation electrical salf-walking stair climbing wheelchair cars to travel.
