Description
Technical field
This utility model belongs to a kind of small vehicles, but the dual-purpose electric wheelchair of particularly a kind of stair activity and level road walking belongs to lower limb disability and old, weak, patient's special equipment technical field.
Background technology
Lower limb disability and walking old, weak, patient for convenience, meeting the tendency has produced wheelchair, and to there being three kinds, a kind of is the wheelchair that does not have power to wheelchair greatly, walks by guardian's implementation or by taking advantage of a person oneself to operate, but is only limited to the level road walking; Second kind is electric wheelchair, equally also is only limited to the level road walking; The third is the electric stair climbing chair, uses but be only limited to stair activity again, and level road can only carry out push-and-pull by manpower, can not use electric walking, many Related products are arranged at present, but price is high abroad.Therefore, but a kind of moderate cost, diverse in function, simple in structure, a kind of stair activity of smooth running and the dual-purpose electric wheelchair of level road walking need to be proposed.
The utility model content
Of the present utility model is in order to address the above problem, and provides a kind of and can help lower limb disability and old, weak, patient to realize light stair activity, level road walking and further alleviate a kind of stair activity of household's burden and the dual-purpose electric wheelchair of level road walking.
This utility model is achieved through the following technical solutions: but the dual-purpose electric wheelchair of a kind of stair activity and level road walking, be provided with seat frame, be provided with motor in the seat frame, driving chain, battery, decelerator, bottom, seat frame back is provided with the differential driving and takes out, differential driving shaft two ends are equipped with combination and drive wheel body, combination drives on the wheel body and is connected with circular star-wheel, combination drives in the wheel body brake is installed, seat frame top is provided with back of the body frame and headrest, charging socket back of the body frame both sides are provided with handrail, and handrail is provided with battery main switch, speed adjusting lever, left and right sides braking in a turn handle and two-direction switch, headrest are provided with the braking lock, be connected with foot rest below the seat frame front end, the foot rest middle part is provided with deflecting roller, is provided with stretcher cleat above, and front end is equipped with bumper.
This utility model further improves and the additional project of enforcement is:
Battery is powered to motor by battery main switch, motor drives decelerator by driving chain, decelerator rotates together by the combination driving wheel body that driving chain drives on differential driving shaft and the differential driving shaft, at described differential driving shaft, it is characterized in that: the differential driving shaft is when turning, can one side brake differential turning operation principle identical with the automotive rear axle differential gear of rear bridge driven, described combination drives wheel body, it is characterized in that: combination drives wheel body and is made of six or seven circular star-wheels and six or seven fanning strips combination assemblings.Pull down fanning strip during stair activity, load onto fanning strip during the level road walking circular wheel body realization level road of its formation or stair activity are steadily walked.
The beneficial effects of the utility model are: because this utility model adopted power parts such as battery, motor, decelerator, driving chain to drive, as long as by simple dismounting fanning strip, can realize that stair activity and level road steadily walk.The utlity model has rational in infrastructurely, flexible operation is light, safe and reliable and cheap advantage.
