Description
Affiliated field
This utility model belongs to mechanical field, is specifically related to a kind of structure of multifunctional electric wheel Wheel-chair.
Background technology
Wheelchair generally all is manually, as hand wheelchair, swing wheelchair, implementation wheelchair etc.Electric wheel-chair vehicle is on the basis of old tricycle, adds that the drive system of electric bicycle forms, and it can only travel on level road.The old man who lives upstairs must have the place of parking specially.Charging also will be taken battery upstairs and fill, and is very inconvenient.Still there is not a kind of multifunctional electric wheel Wheel-chair to come into the market at present.
Summary of the invention
This utility model purpose is a kind of multifunctional electric of a design wheel Wheel-chair, solves people with disability and old people's trip difficulty and the heavy patient that the lives upstairs difficult problem of curing the disease.
Technical solutions of the utility model are: multifunctional electric wheelchair is interconnected it by vehicle frame and is formed by travel one group of star-wheel of the front-wheel of motor and band upset motor of band, seat is positioned on the star-wheel support, connect a deflecting roller at the car rear portion, handgrip links to each other with front-wheel by front fork, and the upset motor connects turbine and worm decelerator provides driving force for star-wheel.
Adopt the principle of tri-star wheel upset and star-wheel rotation, make wheelchair upwards soaring forward, the power of star-wheel upset drives direct current generator by accumulator, utilizes worm and gear to slow down and makes the main shaft slow rotation.
When multifunctional wheelchair when travel in the level land, the front-wheel motor that travels provides power, star-wheel to keep normal transport condition under without hindrance situation for advancing, when the wheel Wheel-chair is gone upstairs, parallelogram vehicle frame distortion back front-wheel lifts, star-wheel will be at the transport condition that stops the down conversion star-wheel of stair, realize the action of climbing, the duty in the time of downstairs is with similar upstairs.
This utility model has solved the needs that people's stair activity of people with disability or old walking disorder carries out outdoor activities preferably.
